Barreras y facilitadores para el uso de las guías de práctica clínica por residentes de Medicina Familiar y Comunitaria: estudio cualitativo con grupos focales / Barriers and facilitators for the use of clinical practice guidelines by Family and Community Medicine residents: qualitative study with focus groups

Objetivo: identificar barreras y facilitadores para el uso de las guías de práctica clínica (GPC) por residentes de Medicina Familiar y Comunitaria.Métodos: metodología cualitativa. Se formaron tres grupos focales, total 28 residentes de tercer y cuarto año de las siete unidades docentes multiprofesionales de Atención Familiar y Comunitaria de Madrid. Los temas explorados fueron: conocimiento, comprensión, utilidad y uso de GPC. Las categorías elegidas para agrupar el discurso se elaboraron siguiendo el Manual metodológico de GuíaSalud. Análisis sociológico bajo la perspectiva fenomenológica.Resultados: las barreras relacionadas con la formación fueron el modelo de formación recibida para adquirir las habilidades necesarias, la falta de conocimientos para evaluar la calidad de las guías y un limitado conocimiento de los buscadores. Entre las barreras del contexto social y del sistema sanitario, se identificaron el conflicto con las expectativas del paciente, con las recomendaciones de otros especialistas, las características de los pacientes que consultan en Atención Primaria (AP) y la limitación de tiempo en las consultas. Como facilitadores se identificaron la motivación personal, los conocimientos y el modelo de práctica profesional del tutor y que las GPC fueran claras, breves y en diversos formatos.Conclusiones: los residentes dan valor a las GPC como herramientas docentes, de ayuda a la toma de decisiones y para desempeñar un mejor ejercicio profesional, aunque encuentran dificultades y limitaciones en su uso. El papel del tutor se identifica como clave; la formación, motivación y el modelo de práctica del tutor son considerados como los mayores facilitadores.(AU)

Aim: to identify barriers and facilitators for the use of Clinical Practice Guidelines (CPG) by Family and Community Medicine residents.Method: qualitative methodology. Three focus groups were set up, with a total of 28 participants, 3rd and 4th year residents of the 7 Multiprofessional Family and Community Care Teaching Units of Madrid. The topics explored were based on knowledge, understanding, usefulness and use of CPG. The categories chosen for discussion were drawn up according to the GuiaSalud Methodological Manual. Sociological analysis was performed using a phenomenological approach.Results: the barriers related to training were the training model received to acquire the necessary skills, the lack of knowledge to evaluate the quality of guidelines and a limited knowledge of the search engines. Among the barriers related to social context and health system, conflict with the patient's expectations or with the recommendations of other specialists, the characteristics of patients who consult in primary care and the limited time available for consultations were all identified. Personal motivation, the tutor’s knowledge and professional practice model and clear, brief CPGs and in various formats were all identified as facilitators. Conclusions: residents value CPGs as teaching and decision-making tools, as well as a tool to improve their professional practice. However, they detect difficulties and limitations in their use. Training, motivation and the tutor's practice model are considered to be among the greatest facilitators.(AU)

Burden in caregivers of primary care patients with dementia: influence of neuropsychiatric symptoms according to disease stage (NeDEM project).

BACKGROUND: Caregiver burden is related to personal factors and patient characteristics and is greater when neuropsychiatric symptoms (NPSs) are present. OBJECTIVE: Estimate the prevalence of burden among caregivers of dementia patients and its association with NPSs and identify NPSs causing greater caregiver distress according to dementia stage. METHODS: A cross-sectional observational study in caregivers of noninstitutionalized dementia patients was conducted. Caregiver variables were sociodemographic, time of care, NPS-associated distress based on the Neuropsychiatric Inventory Caregiver Distress Scale (NPI-D) and burden based on the Zarit Burden Interview (ZBI). Patient variables were time since disease onset, Global Deterioration Scale (GDS) disease stage, functional assessment and NPS presence and intensity according to the Neuropsychiatric Inventory (NPI). The mean ZBI score, prevalence of burden and NPI-D score with 95% CIs at each dementia stage were estimated. Factors associated with burden were identified by multivariate analysis. RESULTS: Of the 125 caregivers included, 77.6% were women, with a mean age of 60.7 (± 14.3) years; 78.4% (95%CI: 71.0; 86.0) experienced burden. The mean ZBI score was 12.3 (95%CI: 11.6; 12.9) and increased according to NPS number (p = 0.042). The NPSs causing the most burden were disinhibition (93.5%), irritability (87.3%) and agitation (86.1%). Agitation, apathy, and sleep disorders were the NPSs generating the greatest overall caregiver distress; depression (max NPI-D 1.9), hyperactivity (max NPI-D 2.1), and psychosis symptoms (max NPI-D 1.6) generated the greatest distress at stage GDS 3, stages GDS 4-5, and stages GDS 6-7, respectively. The NPI score (OR = 1.0, 95%CI 1.0; 1.1), intensity of irritability (OR = 1.2, 95%CI 1.0; 1.6), disinhibition (OR = 2.6, 95%CI 1.1; 5.8) and hyperactivity subsyndrome (OR = 1.1, 95%CI 1.0; 1.2) were associated with caregiver burden. Other associated factors were female gender (OR = 6.0, 95%CI 1.6; 22.8), ≥ 8 h daily care (OR = 5.6, 95%CI 1.4; 22.8), working outside the home (OR = 7.6, 95%CI 1.8; 31.8), living with the patient (OR = 4.5, 95%CI 1.1; 19.6), kinship (OR = 5.4, 95%CI 1.0; 28.2) and lower patient education (OR = 8.3, 95%CI 2.3; 30.3). CONCLUSIONS: The burden on caregivers of dementia patients is high and associated with NPS presence and intensity. Disinhibition and irritability caused the highest burden. Depression, hyperactivity and psychosis produce more distress in mild, mild-moderate and severe dementia, respectively.

Impact of hypertension diagnosis on morbidity and mortality: a retrospective cohort study in primary care.

BACKGROUND: Hypertension is responsible for a huge burden of disease. The aim of this study was to evaluate the impact of newly diagnosed hypertension on the occurrence of kidney or cardiovascular events (K/CVEs) and on mortality among community dwellers. METHODS: Retrospective cohort study, conducted from January, 2007, to December, 2018. All patients (age > 18) newly diagnosed with hypertension and no previous K/CVEs in 2007 and 2008, in the primary care centers of Madrid (Spain) (n = 71,770), were enrolled. The control group (n = 72,946) included patients without hypertension, matched by center, sex and age. The occurrence of kidney or CV events, including mortality from these causes and total mortality were evaluated using Cox regression and multistate models. Data were collected from three sources: personal data from administrative records, clinical data from medical records, and mortality data from regional and national databases. RESULTS: The median follow-up was 138.61 months (IQR: 124.68-143.97 months). There were 32,896 K/CVEs (including 3,669 deaths from these causes) and 12,999 deaths from other causes. Adjusted for sex, smoking, diabetes and socioeconomic status, K/CVEs HR was 4.36 (95% CI: 3.80-5.00) for diagnoses before 45 years of age, 2.45(95% CI: 2.28- 2.63) for diagnosis between 45 to 54 years, and HR decreased to 1.86 (95% CI: 1.64-210) for diagnoses over age 85. Total mortality risk was only higher for hypertension diagnosed before 55 years of age (HR: 2.47, 95% CI: 1.90-3.19 for ages 18 to 44; and HR: 1.14, 95% CI: 1.02-1.28 for ages 45 to 54). CONCLUSION: The diagnosis of hypertension in the community environment, in patients without evidence of previous kidney or CV disease, is associated with a large increase in the risk of K/CVEs, but especially in individuals diagnosed before the age of 55. This diagnosis is only associated with an increase in kidney or cardiovascular mortality or overall mortality when it occurs before age 55.

Effectiveness of a game-based educational strategy e-EDUCAGUIA for implementing antimicrobial clinical practice guidelines in family medicine residents in Spain: a randomized clinical trial by cluster.

BACKGROUND: Clinical practice guidelines (CPGs) have teaching potential for health professionals in training clinical reasoning and decision-making, although their use is limited. The objective was to evaluate the effectiveness of a game-based educational strategy e-EDUCAGUIA using simulated clinical scenarios to implement an antimicrobial therapy GPC compared to the usual dissemination strategies to improve the knowledge and skills on decision-making of family medicine residents. Additionally, adherence to e-EDUCAGUIA strategy was assessed. METHODS: A multicentre pragmatic cluster-randomized clinical trial was conducted involving seven Teaching Units (TUs) of family medicine in Spain. TUs were randomly allocated to implement an antimicrobial therapy guideline with e-EDUCAGUIA strategy ( intervention) or passive dissemination of the guideline (control). The primary outcome was the differences in means between groups in the score test evaluated knowledge and skills on decision-making at 1 month post intervention. Analysis was made by intention-to-treat and per-protocol analysis. Secondary outcomes were the differences in mean change intrasubject (from the baseline to the 1-month) in the test score, and educational game adherence and usability. Factors associated were analysed using general linear models. Standard errors were constructed using robust methods. RESULTS: Two hundred two family medicine residents participated (104 intervention group vs 98 control group). 100 medicine residents performed the post-test at 1 month (45 intervention group vs 55 control group), The between-group difference for the mean test score at 1 month was 11 ( 8.67 to 13.32) and between change intrasubject was 11,9 ( 95% CI 5,9 to 17,9). The effect sizes were 0.88 and 0.75 respectively. In multivariate analysis, for each additional evidence-based medicine training hour there was an increase of 0.28 points (95% CI 0.15-0.42) in primary outcome and in the change intrasubject each year of increase in age was associated with an improvement of 0.37 points and being a woman was associated with a 6.10-point reduction. 48 of the 104 subjects in the intervention group (46.2%, 95% CI: 36.5-55.8%) used the games during the month of the study. Only a greater number of evidence-based medicine training hours was associated with greater adherence to the educational game ( OR 1.11; CI 95% 1.02-1.21). CONCLUSIONS: The game-based educational strategy e-EDUCAGUIA shows positive effects on the knowledge and skills on decision making about antimicrobial therapy for clinical decision-making in family medicin residents in the short term, but the dropout was high and results should be interpreted with caution. Adherence to educational games in the absence of specific incentives is moderate. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02210442 . Registered 6 August 2014.

Health Related Quality of Life in Major Depressive Disorder: evolution in time and factors associated.

Major Depressive Disorder (MDD) is the most prevalent mental disorder. We aimed to analyze which factors were associated to their Health-Related Quality of Life (HRQoL) perception in patients diagnosed of MDD and how they evolved over six months.

Neuropsychiatric symptoms and subsyndromes in patients with different stages of dementia in primary care follow-up (NeDEM project): a cross-sectional study.

BACKGROUND: The objective was to describe the prevalence and intensity of neuropsychiatric symptoms (NPSs) isolated and grouped into subsyndromes in patients with dementia in primary care (PC) to analyse their distribution based on stages of dementia and the relationship between them and the intensity of symptoms. METHODS: Design: Cross-sectional study. SETTING AND POPULATION: Patients with dementia, not institutionalized, in a PC follow-up. VARIABLES: Sociodemographic and clinical variables. Assessment instruments: The frequency and intensity of NPSs were measured with the Neuropsychiatric Inventory (NPI), and the stages of dementia with the Global Deterioration Scale (GDS). STATISTICAL ANALYSIS: The number of NPSs per patient, the mean NPI value, and the prevalence and intensity of NPSs isolated and grouped into subsyndromes were calculated, as were their 95% confidence intervals (CIs). The analyses were performed on an overall basis and by GDS scores. To analyse the association between the NPI and GDS scores, multivariate analysis was performed with a generalized linear model. RESULTS: Overall, 98.4% (95% CI 94.5;99.8) of the patients presented some type of NPS, with an average of five symptoms per patient. The most frequent symptoms were apathy [69.8% (95% CI 61.1;77.5)], agitation [55.8% (95% CI 46.8;64.5)] and irritability [48.8% (95% CI 39.9;57.8)]. The more intense NPSs were apathy [NPI 3.2 (95% CI 2.5;3.8)] and agitation [NPI 3.2 (95% CI 2.5;4.0)]. For subsyndromes, hyperactivity predominated [86.0% (95% CI 78.8;91.5)], followed by apathy [77.5% (95% CI 69.3;84.4]). By phase of dementia, the most common isolated symptom was apathy (60.7-75.0%). Affective symptoms and irritability predominated in the initial stages, and psychotic symptoms predominated in advanced stages. The mean NPI score was 24.9 (95% CI 21.5;28.4) and increased from 15.6 (95% CI 8.2;23.1) for GDS 3 to 28.9 (95% CI 12.6;45.1) for GDS 7. Patients with in the most advanced stages of dementia presented an NPI score 7.6 (95% CI 6.8;8.3) points higher than the score for mild dementia with adjustment for the other variables. CONCLUSIONS: A high prevalence of NPSs was found among patients with dementia treated in PC. Symptoms change and increase in intensity as the disease progresses. Scales such as the NPI allow these symptoms to be identified, which may facilitate more stage-appropriate management.

La calidad de vida relacionada con la salud en el trastorno depresivo mayor: factores asociados con su evolución / Health-related quality of life in major depressive disorder: factors associated with its evolution

Introducción. La Depresión Mayor (DM) es el trastorno de salud mental más prevalente. Se pretende analizar el peso de los factores asociados a la percepción de la Calidad de Vida Relacionada con la Salud (CVRS) en pacientes con diagnóstico de DM y su evolución durante seis meses. Metodología. Se incluyeron 432 sujetos con DM (DSMIV-TR) de consultas hospitalarias, centros de salud mental y centros de atención primaria en País Vasco, Madrid y Canarias. Se siguió a los pacientes durante 6 meses. Se recogieron variables clínicas, sociodemográficas y de abordaje terapéutico. La CVRS se midió mediante el EQ-5D-5L, expresado como “utilidades”. Se construyeron Modelos Lineales Generalizados para responder los objetivos. Resultados. Las mujeres, las personas de mayor edad, los grupos sociales menos favorecidos y aquellos con mayor comorbilidad “orgánica” expresaron una peor CVRS inicial. A los 6 meses permanecían en seguimiento 305 sujetos. El cambio medio en las “utilidades” fue de 0,033 (IC95%: 0,008-0,059), y de 0,132 (IC95%: 0,093-0,171) en los 109 sujetos (35,51%) que expresaron mejoría en su estado de salud. Se asociaron negativamente con la evolución de la CVRS la comorbilidad “orgánica”, la presencia de trastornos de la conducta alimentaria, una mayor edad, el pertenecer a grupos socioeconómicos desfavorecidos o la necesidad de un mayor esfuerzo terapéutico. Conclusiones. La DM se asocia con un gran impacto en la CVRS, que revierte parcialmente en el grupo con buena evolución clínica. La mayor edad, la comorbilidad y el grupo socioeconómico se asocian a una peor evolución de la CVRS.(AU)

Introduction. Major Depressive Disorder (MDD) is the most prevalent mental disorder. We aimed to analyze which factors were associated to their Health-Related Quality of Life (HRQoL) perception in patients diagnosed of MDD and how they evolved over six months. Methods. We included 432 subjects with MDD (DSM-IVTR) from hospital consultations, mental health centres and primary care centres in Basque Country, Madrid and Canary Islands. Patients were followed for 6 months. Clinical, sociodemographic and therapeutic variables were collected. HRQoL was measured by EQ-5D-5L, expressed as “utilities”. Generalized Linear Models were constructed to meet the objectives. Results. Women, older people, disadvantaged social groups and those with higher “physical comorbidity” expressed a worse HRQoL at inclusion. At 6 months, 305 subjects remained in follow-up. The average change in “utilities” was 0.033 (CI95%: 0.008-0.059), and 0.132 (CI95%: 0.093-0.171) in the 109 subjects (35.51%) who expressed improvement in their health status. “Physical comorbidity”, the presence of eating disorders, older age, belonging to disadvantaged socioeconomic groups or the need for greater therapeutic effort were negatively associated with HRQoL evolution. Conclusion. MDD is associated with a great impact on HRQoL, which partially reverts when the patients showed good clinical evolution. Older age, comorbidity and disadvantaged socioeconomic group are associated with a worse evolution of HRQOoL.(AU)

Risk aversion, trust in institutions and contingent valuation of healthcare services: trying to explain the WTA-WTP gap in the Dutch population.

BACKGROUND: The preferences of citizens are a basic element to incorporate into the decision-making process when planning health policies. Contingent valuation (CV) is a common method for calculating the value for citizens that new technologies, interventions, and the provision of services or policies have. However, choosing the correct CV tool may not be a neutral decision. This work aims to assess the substitution of a healthcare service by comparing valuation differences between the willingness to pay (WTP) for the maintenance of the service versus the willingness to accept compensation (WTA) for its substitution, both of which are related to subject characteristics, with a particular focus on trust in institutions and risk aversion. METHODS: A CV study was designed to study Dutch population preferences when physician assistants replace anaesthesiologists. Differences between the distributions of WTA and WTP were compared through full decomposition methods, and conditional quantile regression was performed. RESULTS: Nearly two-thirds of surveyed citizens expressed null values for WTA and WTP. The other third systematically reported a value of WTA higher than that of WTP, which increased further with lower income and the possible presence of a strategic bias. In contrast, being more than 65 years old, having trust in government, and preferring anaesthesiologists decreased the WTA-WTP difference. Risk aversion had no clear association with the WTA-WTP gap. CONCLUSIONS: Known differences between the perceived value of health services from the perspective of gains and losses could be related to people's characteristics. Trust in government but not aversion to risk was related to the WTA-WTP differences. Identifying a profile of citizens who are averse to losing health services should be considered when designing and implementing health services or interventions or making disinvestment decisions.

Objetivo: Analizar el papel de las unidades docentes (UD) de atención familiar y comunitaria como agentes facilitadores de la implementación de guías de práctica clínica (GPC) y los factores asociados a un mayor esfuerzo en esta tarea. Material y métodos: Diseño: estudio descriptivo transversal con enfoque analítico. Participantes: UD en España (n=94). Mediciones principales: Variables recogidas mediante encuesta autocumplimentada en 5 dominios: características de las UD, actividad formativa dirigida a la práctica clínica basada en pruebas, importancia atribuida a esta actividad, responsabilidad sobre implementación de GPC y percepción sobre barreras y facilitadores para su uso. Análisis descriptivo y multivariante siendo la variable dependiente el esfuerzo percibido de las UD para implementar GPC. Resultados: Respondieron 45 UD (47,9%). El 42,2% (IC 95%: 27,8-56,6) de sus responsables ha dirigido proyectos de investigación y el 31,1% (IC 95%:17,6- 44,6) ha participado en elaborar GPC. Organizaban una media de 51horas (DE 47,2) de formación en práctica clínica basada en pruebas. El 97,7% (IC 95%:93,3-100) consideraba fundamental que los residentes conozcan y apliquen GPC y el 93,3% (IC 95%: 86,0-100) consideran los tutores responsables de implementarlas. Se relacionaron con un mayor esfuerzo de las UD la participación del responsable en GPC (coef.: 0,58; IC 95%: 0,00-1,16), la importancia dada a que los residentes las conozcan (coef.: 0,89; IC 95%: 0,24-1,54) y que estas parezcan aplicables (coef.: 0,35; IC 95%: –0,01-0,70). Conclusiones: Las UD reconocen la importancia de las GPC y consideran a los tutores responsables de su implementación. El esfuerzo de las UD para implementar GPC se relacionó con la experiencia previa de los responsables, la percepción de aplicabilidad y de necesidad de los residentes.(AU)

Mapping WOMAC Onto the EQ-5D-5L Utility Index in Patients With Hip or Knee Osteoarthritis.

OBJECTIVES: To map the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) onto the EQ-5D-5L in patients with hip or knee osteoarthritis (OA). METHODS: A prospective observational study was conducted on 758 patients with hip or knee OA who completed the EQ-5D-5L and WOMAC questionnaires, of whom 644 completed them both again 6 months later. Baseline data were used to derive mapping functions. Generalized additive models were used to identify to which powers the WOMAC subscales should be raised to achieve a linear relationship with the response. For the modeling, general linear models (GLM), Tobit models, and beta regression models were used. Age, sex, and affected joints were also considered. Preferred models were selected based on Akaike and Bayesian information criteria, adjusted R2, mean absolute error (MAE), and root mean squared error (RMSE). The functions were validated with the follow-up data using MAE, RMSE, and the intraclass correlation coefficient. RESULTS: The preferred models were a GLM with Pain2+Pain3+Function+Pain·Function as covariates and a beta model with Pain3+Function+Function2+Function3 as covariates. The adjusted R2 were similar (0.6190 and 0.6136, respectively). The predictive performance of these models in the validation sample was similar and both models showed an overprediction for health states worse than death. CONCLUSION: To our knowledge, these are the first functions mapping the WOMAC onto the EQ-5D-5L in patients with hip or knee OA. They showed an acceptable fit and precision and could be very useful for clinicians and researchers when cost-effectiveness studies are needed and generic preference-based health-related quality of life instruments to derive utilities are not available.

Impact of lower limb osteoarthritis on health-related quality of life: A cross-sectional study to estimate the expressed loss of utility in the Spanish population.

OBJECTIVE: Osteoarthritis of the lower limb (OALL) worsens health-related quality of life (HRQL), but this impact has not been quantified with standardized measures. We intend to evaluate the impact of OALL on HRQL through measures based on individual preferences in comparison to the general population. METHODS: A cross-sectional study was designed. A total of 6234 subjects aged 50 years or older without OALL were selected from the Spanish general population (National Health Survey 2011-12). An opportunistic sample of patients aged 50 years or older diagnosed with hip (n = 331) or knee osteoarthritis (n = 393), using the American Rheumatism Association criteria, was recruited from six hospitals and 21 primary care centers in Vizcaya, Madrid and Tenerife between January and December 2015. HRQL was measured with the EQ-5D-5L, and the results were transformed into utility scores. Sociodemographic variables (age, sex, social group, cohabitation), number of chronic diseases, and body mass index were considered. The clinical stage of OALL was collected using the Western Ontario and McMaster Universities Osteoarthritis Index and the Oxford hip score and Oxford knee score. Generalized linear models were constructed using the utility index as the dependent variable. RESULTS: HRQL expressed by OALL patients was significantly worse than this of the general population. After adjustment for sociodemographic and clinical characteristics, the mean utility loss was -0.347 (95% CI: -0.390, -0.303) for osteoarthritis of the hip and -0.295 (95% CI: -0.336, -0.255) for osteoarthritis of the knee. OALL patients who were treated at a hospital had an additional utility loss of -0.112 (95% CI: -0.158, -0.065). CONCLUSION: OALL has a great impact on HRQL. People with OALL perceive a utility loss of approximately 0.3 points compared to the general population without osteoarthritis, which is very high in relation to the utility loss reported for other chronic diseases and for arthritis in general.

Análisis de la consulta enfermera de Atención Primaria en la Comunidad de Madrid (España) / An analysis of primary nurse consultation in the Community of Madrid

Objetivo: Analizar las características de la consulta enfermera en Atención Primaria e identificar los factores asociados a los diferentes tipos de actividad. Método: Estudio observacional multicéntrico transversal sobre 662 consultas de 164 enfermeras diferentes (23 centros de salud, Comunidad de Madrid). La consulta se clasificó según una propuesta de consenso en: «actividades de prevención» (AdP), «déficit de autocuidados» (DA), «afrontamiento y adaptación» (AyA) y «procedimientos diagnósticos y terapéuticos» (PDyT). Se recogieron características sociodemográficas, de necesidad en salud y relativas a la consulta. Se hizo un análisis inferencial bivariante y se construyeron modelos multivariantes explicativos. Resultados: El 63,6% (IC del 95%: 59,9-67,3%) de las consultas fueron PDyT. En el 24,3% (IC del 95%: 21,0- 27,7%) de los casos la consulta era a demanda. No hubo diferencias en el tipo de consultas por género (p = 0,858), ni para inmigrantes (p = 0,428). Los sujetos de clases sociales superiores ocuparon con más frecuencia consultas de AdP (p = 0,007). No había otras diferencias en accesibilidad. Las consultas de PDyT se relacionaron con la existencia de hospitalizaciones previas (OR: 1,191; IC del 95%: 1,088-1,304), o el uso previo de servicios (consulta enfermera OR: 1,002, IC del 95%: 1,000-1,003; consulta médica OR: 1,003, IC del 95%: 1,000-1,006). Conclusiones: La consulta enfermera en nuestro medio se dirige preferentemente a la realización de procedimientos y predomina la consulta autoconcertada respecto a la demanda. No se detectan inequidades en la accesibilidad, pero el tipo de atención para diferentes grupos sociales no fue homogéneo

Objective: to analyse the characteristics of primary care nurse consultation and to identify the factors associated with different types of activity. Method: A cross-sectional multicentre observational study in 23 health centres (Community of Madrid), on 164 different nurses. The consultation was classified according to a consensus proposal in: "preventive activities" (PA), "self-care deficit" (SD), "coping and adaptation" (CA) and "diagnostic and therapeutic procedures" (DTP). Sociodemographic characteristics, health needs, and consultation characteristics were collected. A bivariate inferential analysis was made, and explanatory multivariate models were constructed. Results: Of the total consultations 63.6% (95% CI: 59.9-67.3%) were classified as DTP. The consultation was directly requested by the patient in 24.3% (95% CI: 21.0- 27.7%) of the cases. There were no differences in the type of consultations by gender (P=.858), or for immigrants (P=.428). Subjects from higher social classes more frequently attended PA consultations (P=.007). There were no other differences in accessibility. The DTP consultations related to previous hospitalizations (OR: 1.191, 95% CI: 1.088-1.304), or the previous use of services (nurse consultation OR: 1.002, 95% CI: 1.000-1.003, medical consultation OR: 1.003, 95% CI: 1.000-1.006). Conclusions: The nurse consultation is mainly aimed at carrying out procedures and previously arranged consultation prevails over patient demanded consultation. No inequities in accessibility were detected, but the type of care for different social groups was not homogeneous

An analysis of primary nurse consultation in the Community of Madrid. / Análisis de la consulta enfermera de Atención Primaria en la Comunidad de Madrid (España).

OBJECTIVE: to analyse the characteristics of primary care nurse consultation and to identify the factors associated with different types of activity. METHOD: A cross-sectional multicentre observational study in 23 health centres (Community of Madrid), on 164 different nurses. The consultation was classified according to a consensus proposal in: "preventive activities" (PA), "self-care deficit" (SD), "coping and adaptation" (CA) and "diagnostic and therapeutic procedures" (DTP). Sociodemographic characteristics, health needs, and consultation characteristics were collected. A bivariate inferential analysis was made, and explanatory multivariate models were constructed. RESULTS: Of the total consultations 63.6% (95% CI: 59.9-67.3%) were classified as DTP. The consultation was directly requested by the patient in 24.3% (95% CI: 21.0- 27.7%) of the cases. There were no differences in the type of consultations by gender (P=.858), or for immigrants (P=.428). Subjects from higher social classes more frequently attended PA consultations (P=.007). There were no other differences in accessibility. The DTP consultations related to previous hospitalizations (OR: 1.191, 95% CI: 1.088-1.304), or the previous use of services (nurse consultation OR: 1.002, 95% CI: 1.000-1.003, medical consultation OR: 1.003, 95% CI: 1.000-1.006). CONCLUSIONS: The nurse consultation is mainly aimed at carrying out procedures and previously arranged consultation prevails over patient demanded consultation. No inequities in accessibility were detected, but the type of care for different social groups was not homogeneous.

Explaining differences in perceived health-related quality of life: a study within the Spanish population / Explicar las diferencias en cuanto a la calidad de vida percibida relacionada con la salud: estudio realizado en la población española

Objective: To assess the burden of several determinants on health-related quality of life (HRQOL) and to study its heterogeneity among the different Spanish regions. Method: Cross-sectional study. Data were obtained from the Spanish National Health Survey (2012), and HRQOL was measured using the EQ-5D-5L questionnaire (utility and visual analogue scale -VAS- scores). Demographic variables, physical health condition, social variables, mental health status, and lifestyle were also analysed. Tobit regression models were employed to study the relationships between expressed HRQOL and personal characteristics. Results: A total of 20,979 surveys were obtained. Of them, 62.4% expressed a utility score of 1, corresponding to perfect health (95%CI: 61.8%-63.2%), and 54.2% showed VAS scores ≥80 (95%CI: 53.5%-54.9%). HRQOL was mainly described as a function of age, chronic limitation in daily activities, and mental health status. Belonging to a higher-class strata and physical activity were related to better self-perceived HRQOL. Ageing worsened perceived HRQOL, but did not influence its determinants, and differences in HRQOL by regions were also not significant after model adjustment. Conclusion: HRQOL perception in the Spanish population varied slightly depending on the measure used (utilities index or VAS). Age, chronic limitations in daily life, and mental health status best explained the variability in perception, and no meaningful differences in HRQOL perception among regions were found after adjustment

Objetivo: Evaluar la carga de ciertos determinantes de la calidad de vida relacionada con la salud (CVRS) y su heterogeneidad entre diferentes regiones españolas. Métodos: Estudio transversal. Utilizando datos de la Encuesta Nacional de Salud (2012), se midió la CVRS con el cuestionario EQ5D-5L (utilidad y escala visual analógica [EVA]). Se analizaron variables demográficas, estado de salud, variables sociales, salud mental y estilos de vida, utilizando modelos Tobit. Resultados: Se incluyeron 20.979 encuestas. El 62,4% de los sujetos expresó una utilidad de 1, perfecta salud (intervalo de confianza del 95% [IC95%]: 61,8% -63,2%), y el 54,2% mostró puntuaciones en la EVA ≥80 (IC95%: 53,5%-54,9%). La CVRS se vio modificada fundamentalmente por la edad, la limitación crónica en las actividades diarias y el estado de salud mental. La clase social alta y la actividad física aparecían relacionadas con una mejor CVRS. La edad empeoró la percepción de la CVRS, pero no se asoció con un cambio en la influencia de sus determinantes. Después de ajustar los modelos, no había diferencias en la CVRS en las diferentes regiones. Conclusión: La percepción de la CVRS en la población española varió dependiendo de la medida utilizada (utilidades o EVA). La edad, las limitaciones crónicas en la vida diaria y el estado de salud mental explicaban fundamentalmente las diferencias en la CVRS, y las diferencias entre regiones se explicaron principalmente por diferentes características poblacionales

Psychometric properties of the EQ-5D-5L in patients with hip or knee osteoarthritis: reliability, validity and responsiveness.

PURPOSE: To study the psychometric properties, including reliability, validity and responsiveness, of the Spanish EQ-5D-5L questionnaire for patients with hip or knee osteoarthritis (OA). METHODS: We included 758 patients with hip or knee OA who completed the EQ-5D-5L and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) at baseline, of whom 644 also did 6 months later. The EQ-5D-5L contains five questions from which a utility index is derived. The WOMAC covers three dimensions: pain, stiffness and physical function. Floor and ceiling effects were calculated. Reliability was assessed using Cronbach's alpha. Convergent validity was tested using the Spearman correlation coefficient between EQ-5D-5L and WOMAC. We examined known-groups validity by comparing the EQ-5D-5L between subgroups defined by WOMAC scores using ANOVA or the Kruskal-Wallis test. Effect sizes were calculated to assess responsiveness, and minimal clinically important difference (MCID) was estimated. RESULTS: The EQ-5D-5L showed minimal floor and ceiling effects (< 3%). Cronbach's alpha was 0.86. The EQ-5D-5L index was strongly correlated with WOMAC pain and function scores (- 0.688 and - 0.782). Patients with higher WOMAC scores had significantly (p < 0.0001) lower EQ-5D-5L index. The 20.19% had hip or knee replacement during the follow-up. Effect sizes were small among non-surgical patients, but > 0.80 among "improved" surgical patients, being the MCID for improvement 0.32 points. CONCLUSIONS: The results support the reliability, validity and responsiveness of the EQ-5D-5L, overcoming the limitations of the EQ-5D-3L in these patients. Therefore, the EQ-5D-5L could be very useful as an outcome measure, at least in patients with hip or knee OA.

"Gaining or losing": The importance of the perspective in primary care health services valuation.

RATIONALE AND OBJECTIVES: Economic theory classifies an intervention as socially beneficial if the total Willingness to Pay (WTP) of those who gain exceeds the total Willingness to accept (WTA) of those who are harmed. This paper examines the differences in health system users' valuation of a health care service in primary care setting based on the WTP and WTA perspectives, discussing the impact of personal and service variables, including risk attitudes, on these disparities. METHOD: Six hundred and sixty two subjects who asked for care in health centres in the Region of Madrid (Spain) were interviewed, using the contingent valuation method to estimate WTP and WTA. Patient sociodemographic characteristics, health needs, satisfaction with the service and risk attitude and behaviour under risk (measured by self-reported scales and lottery games respectively) were collected. Generalised Linear Models were used to estimate the association between the explanatory variables and the WTA/WTP ratio. RESULTS: We obtained the WTA/WTP ratio for 570 subjects (mean 1.66 CI 95%: 1.53-1.79; median 1, interquartile range 1-2). People with higher education or in high social groups expressed WTA values closest to WTP. The opposite occurred in patients with the greatest health needs or who were born abroad. Self-reported expression of risk aversion appeared also related to increases in the WTA/WTP ratio. Satisfaction with the service evaluated was the most influential factor in the WTA/WTP ratio. CONCLUSION: Health need, difficulty in obtaining substitutes and satisfaction with the service could serve for profiling people averse to loss for health care services in primary care setting. Self-reported expression of risk aversion could also be related to increases in the WTA/WTP ratio. This would mean that these characteristics should be taken into account both in the design and implementation of new healthcare interventions, as in the making decision for disinvestment.

Effectiveness of a strategy that uses educational games to implement clinical practice guidelines among Spanish residents of family and community medicine (e-EDUCAGUIA project): a clinical trial by clusters.

BACKGROUND: Clinical practice guidelines (CPGs) have been developed with the aim of helping health professionals, patients, and caregivers make decisions about their health care, using the best available evidence. In many cases, incorporation of these recommendations into clinical practice also implies a need for changes in routine clinical practice. Using educational games as a strategy for implementing recommendations among health professionals has been demonstrated to be effective in some studies; however, evidence is still scarce. The primary objective of this study is to assess the effectiveness of a teaching strategy for the implementation of CPGs using educational games (e-learning EDUCAGUIA) to improve knowledge and skills related to clinical decision-making by residents in family medicine. The primary objective will be evaluated at 1 and 6 months after the intervention. The secondary objectives are to identify barriers and facilitators for the use of guidelines by residents of family medicine and to describe the educational strategies used by Spanish teaching units of family and community medicine to encourage implementation of CPGs. METHODS/DESIGN: We propose a multicenter clinical trial with randomized allocation by clusters of family and community medicine teaching units in Spain. The sample size will be 394 residents (197 in each group), with the teaching units as the randomization unit and the residents comprising the analysis unit. For the intervention, both groups will receive an initial 1-h session on clinical practice guideline use and the usual dissemination strategy by e-mail. The intervention group (e-learning EDUCAGUIA) strategy will consist of educational games with hypothetical clinical scenarios in a virtual environment. The primary outcome will be the score obtained by the residents on evaluation questionnaires for each clinical practice guideline. Other included variables will be the sociodemographic and training variables of the residents and the teaching unit characteristics. The statistical analysis will consist of a descriptive analysis of variables and a baseline comparison of both groups. For the primary outcome analysis, an average score comparison of hypothetical scenario questionnaires between the EDUCAGUIA intervention group and the control group will be performed at 1 and 6 months post-intervention, using 95 % confidence intervals. A linear multilevel regression will be used to adjust the model. DISCUSSION: The identification of effective teaching strategies will facilitate the incorporation of available knowledge into clinical practice that could eventually improve patient outcomes. The inclusion of information technologies as teaching tools permits greater learning autonomy and allows deeper instructor participation in the monitoring and supervision of residents. The long-term impact of this strategy is unknown; however, because it is aimed at professionals undergoing training and it addresses prevalent health problems, a small effect can be of great relevance.

Risk-Taking Attitudes of Patients who Seek Health Care: An Exploratory Approach through Lottery Games. / La valoración de la actitud ante el riesgo en personas que demandan cuidados en salud: una aproximación mediante juegos de loterías utilizando generalized estimating equations.

BACKGROUND: The characterization of the risk-taking attitude of individuals may be useful for planning health care interventions. It has been attempted to study expressions of risk-taking attitude and evaluate characteristics of a standard lottery game in a population that seeks health care to elicit these attitudes. METHODS: Multicentric cross-sectional study. Demographic and socioeconomic characteristics, quality of life (EuroQol-5D), and health risk behaviors were collected from 662 users of 23 health centers selected by random sampling. Risk-taking attitude was evaluated by means of a self-evaluation scale and two lottery games, (L1 and L2; L2 included the possibility of economic losses). Generalized estimating equations (GEE) explicative models were used to evaluate the variability of risk-taking attitude. RESULTS: Nineteen percent out of interviewed people (CI95%: 15.6-22.6%) expressed a high risk appetite, but only 10.0% (CI95% 7.0 to 13.0) were classified as risk-seeking by L2. It was found association between increased risk appetite and having a better perception of health status (0.110, CI95%: 0,007-0,212) or a higher income (0.010, CI95%: 0.017- 0.123) or smoking status (0.059, CI95%: 0.004- 0.114). Being Spanish was associated with lower risk appetite (-0.105, CI95%: -0.005 --0.205), as being over 65 (-0.031, CI95%:- 0.061- -0.001) or a woman (-0.038, CI95%:-0.064- -0.012). The intraclass correlation coefficient for self-evaluation scale was 0.511 (95% CI: 0.372 to 0.629), 0.571 (95% CI: 0.441 to 0.678) for L1 and 0.349 (95% CI: 0.186-0.493) to L2. CONCLUSIONS: People who seek health care express certain inclination to risk, but this feature is attenuated when methodologies involving losses are used. Risk appetite seems greater in young people, males, people with better health, or more income, and in immigrants. Lottery games such as the proposed ones are a simple and useful tool to estimate individuals' inclination to risk.

OBJETIVO: La caracterización de la actitud ante el riesgo puede ser útil en la planificación de las intervenciones sanitarias. El objetivo fue estudiar la actitud ante el riesgo de una población que demanda cuidados de salud y evaluar la capacidad de un juego de loterías para evidenciar dicha actitud. METODOS: Estudio multicéntrico transversal. Se recogieron características demográficas, socioeconómicas, de calidad de vida y conductas de riesgo en salud de 662 personas usuarias de 23 centros de salud seleccionadas mediante muestreo aleatorio. La actitud ante el riesgo se evaluó mediante una escala subjetiva y mediante dos juegos de azar (L1 y L2; L2 incluía la posibilidad de pérdidas económicas). Se realizaron modelos explicativos para valorar la variabilidad de la propensión al riesgo utilizando Generalized Estimating Equations (GEE). RESULTADOS: El 19,1% (IC95%:15,6-22,6%) de los sujetos expresaron una propensión al riesgo alta, el 10,0% (IC95%:7,0-13,0) fueron clasificados como propensos al riesgo con L2. Se encontró asociación entre una mayor propensión al riesgo y tener mejor percepción del estado de salud (0,110; IC95%:0,007- 0,212) o mayor renta (0,010; IC95%: 0,017- 0,123) o ser fumador (0,059; IC95%: 0,004-0,114). Ser español se relacionaba con menor propensión al riesgo (-0,105; IC95%: -0,205- -0,005), al igual que ser mayor de 65 años (-0,031; IC95%:-0,061- -0,001) o ser mujer (-0,038, IC95%:-0,064- -0,012). El coeficiente de correlación intraclase para la escala subjetiva fue 0,511 (IC95%:0,372-0,629), 0,571 (IC95%:0,441-0,678) para L1 y 0,349 (IC95%:0,186-0,493) para L2. CONCLUSIONES: Las personas que demandan cuidados de salud presentan con frecuencia propensión al riesgo, la cual se atenúa cuando se caracteriza mediante metodologías que implican pérdidas. La propensión al riesgo parece mayor en personas jóvenes, varones, con mejor estado de salud, con mayor renta y en inmigrantes.
