Adjusted morbidity groups and survival: a retrospective cohort study of primary care patients with chronic conditions.

BACKGROUND: Chronic conditions are one of the main determinants of frailty, functional disability, loss of quality of life and the number one cause of death worldwide. This study aimed to describe the survival of patients with chronic conditions who were followed up in primary care according to the level of risk by adjusted morbidity groups and to analyse the effects of sex, age, clinician and care factors on survival. METHODS: This was a longitudinal observational study of a retrospective cohort of patients with chronic conditions identified by the adjusted morbidity group stratifier of the electronic medical records in a primary health centre of the Region of Madrid, which has an assigned population of 18,107 inhabitants. The follow-up period was from June 2015 to June 2018. A description of survival according to the Kaplan-Meier method and Cox proportional hazards multivariate regression model was used to analyse the effects of sex, age, clinician and care factors. RESULTS: A total of 9,866 patients with chronic conditions were identified; 77.4% (7,638) had a low risk, 18.1% (1,784) had a medium risk, and 4.5% (444) had a high risk according to the adjusted morbidity groups. A total of 477 patients with chronic conditions died (4.8%). The median survival was 36 months. The factors associated with lower survival were age over 65 years (hazard ratio [HR] = 1.3; 95% confidence interval [CI] = 1.1-1.6), receiving palliative care (HR = 3.4; 95% CI = 2.6-4.5), high versus low risk level (HR = 2.4; 95% CI = 1.60-3.7), five chronic conditions or more (HR = 1.5; 95% CI = 1.2-2), complexity index (HR = 1.01; 95% CI = 1.02-1.04) and polymedication (HR = 2.6; 95% CI = 2.0-3.3). CONCLUSIONS: There was a gradual and significant decrease in the survival of patients with chronic conditions according to their level of risk as defined by adjusted morbidity groups. Other factors, such as older age, receiving palliative care, high number of chronic conditions, complexity, and polymedication, had a negative effect on survival. The adjusted morbidity groups are useful in explaining survival outcomes and may be valuable for clinical practice, resource planning and public health research.

Use of hospital care services by chronic patients according to their characteristics and risk levels by adjusted morbidity groups.

BACKGROUND: In-hospital care of chronic patients is based on their characteristics and risk levels. Adjusted morbidity groups (AMG) is a population stratification tool which is currently being used in Primary Care but not in Hospitals. The objectives of this study were to describe the use of hospital services by chronic patients according to their risk levels assigned by AMG and to analyze influencing variables. MATERIAL AND METHODS: In this cross-sectional study, patients aged ≥18 years from a healthcare service area classified as chronically ill by the AMG classification system who used their referral hospital services from June 2015 to June 2016 were included. Predisposing and needs factors were collected. Univariate, bivariate and multiple linear regressions were performed. RESULTS: Of the 9,443 chronic patients identified (52.1% of the population in the selected area), 4,143 (43.9%) used hospital care services. Their mean age was 62.1 years (standard deviation (SD) = 18.4); 61.8% were female; 9% were high risk; 30% were medium risk, and 61% were low risk. The mean number of hospital service contacts was 5.0 (SD = 6.2), with 3.8 (SD = 4.3) visits to outpatient clinic, 0.7 (SD = 1.2) visits to emergency departments, 0.3 (SD = 2.8) visits to day hospital, and 0.2 (SD = 0.5) hospitalizations. The factors associated with greater service use were predisposing factors such as age (coefficient B (CB) = 0.03; 95% confidence interval (CI) = 0.01-0.05) and Spanish origin (CB = 3.9; 95% CI = 3.2-4.6). Among the needs factors were palliative care (CB = 4.8; 95% CI = 2.8-6.7), primary caregiver status (CB = 2.3; 95% CI = 0.7-3.9), a high risk level (CB = 2.9; 95% CI = 2.1-3.6), multimorbidity (CB = 0.8, 95% CI = 0.4-1.3), chronic obstructive pulmonary disease (COPD) (CB = 1.5, 95% CI = 0.8-2.3), depression (CB = 0.8, 95% CI = 0.3-1.3), active cancer (CB = 4.4, 95% CI = 3.7-5.1), and polymedication (CB = 1.1, 95% CI = 0.5-1.7). CONCLUSIONS: The use of hospital services by chronic patients was high and increased with the risk level assigned by the AMG. The most frequent type of contact was outpatient consultation. Use was increased with predisposing factors such as age and geographic origin and by needs factors such as multimorbidity, risk level and severe diseases requiring follow-up, home care, and palliative care.

Use of primary and hospital care health services by chronic patients according to risk level by adjusted morbidity groups.

BACKGROUND: Patients with chronic diseases have increased needs for assistance and care. The objective of this study was to describe the characteristics and use of primary care (PC) and hospital care (HC) health services by chronic patients according to risk level based on adjusted morbidity groups (AMG) and to analyze the associated factors. METHODS: Cross-sectional descriptive observational study. Patients from a basic health area classified as chronically ill by the AMG classification system of the Madrid PC electronic medical record were included. Sociodemographic, clinical-care characteristics (classified as predisposing factors or need factors) and service utilization variables were collected. Univariate, bivariate and simple linear regression analyses were performed. RESULTS: The sample consisted of 9866 chronic patients and 8332 (84.4%) used health services. Of these service users, 63% were women, mean age was 55.7 (SD = 20.8), 439 (5.3%) were high risk, 1746 (21.2%) were medium risk, and 6041(73.4%) were low risk. A total of 8226 (98.7%) were PC users, and 4284 (51.4%) were HC users. The average number of annual contacts with PC was 13.9 (SD = 15); the average number of contacts with HC was 4.8 (SD = 6.2). Predisposing factors associated with services utilization at both care levels were: age (B coefficient [BC] = 0.03 and 0.018, 95% CI = 0.017-0.052 and 0.008-0.028, respectively, for PC and HC) and Spanish origin (BC = 0.962 and 3.396, 95% CI = 0.198-1.726 and 2.722-4.070); need factors included: palliative care (BC = 10,492 and 5047; 95% CI = 6457-14,526 and 3098-6995), high risk (BC = 4631 and 2730, 95% CI = 3022-6241 and 1.949-3.512), number of chronic diseases (BC = 1.291 and 0.222, 95% CI = 1.068-1.51 and 0.103-0.341) and neoplasms (BC = 2.989 and 4.309, 95% CI = 1.659-4.319 and 3.629-4.989). CONCLUSIONS: The characteristics and PC and HC service utilization of chronic patients were different and varied according to their AMG risk level. There was greater use of PC services than HC services, although utilization of both levels of care was high. Service use was related to predisposing factors such as age and country of origin and, above all, to need factors such as immobility, high risk, and number and type of chronic diseases that require follow-up and palliative care.

Chronic diseases in the geriatric population: morbidity and use of primary care services according to risk level.

BACKGROUND: Geriatric patients have significant morbidity and greater needs for care and assistance. The objective of this study was to describe the characteristics, morbidity, and use of services in primary care (PC) of patients with chronic diseases older than 65 years according to their risk level assigned by the adjusted morbidity groups (AMG) and to analyse the factors associated with the use of PC services. METHODS: This was a cross-sectional descriptive observational study. Patients older than 65 years from a healthcare service area, classified as chronically ill by the AMG classification system of the PC electronic medical record of the Community of Madrid, were included. Sociodemographic, clinical-care, and PC service utilization variables were collected. Univariate, bivariate and multivariate analyses were done. RESULTS: A total of 3292 chronic patients older than 65 years were identified, of whom 1628 (49.5%) were low risk, 1293 (39.3%) were medium risk and 371 (11.3%) were high risk. Their mean age was 78.1 (SD = 8.1) years and 2167 (65.8%) were women. Their mean number of chronic diseases was 3.8 (SD = 2), 89.4% had multimorbidity and 1550 (47.1%) were polymedicated. The mean number of contacts/year with PC was 19.5 (SD = 18.2) [men: 19.4 (SD = 19.8); women: 19.5 (SD = 17.4)]. The mean number of contacts/year in people over 85 years was 25.2 (SD = 19.6); in people 76-85 years old, it was 22.1 (SD = 20.3); and in people 66-75 years old, it was 14.5 (SD = 13.9). The factors associated with greater use of services were age (B coefficient [BC] = 0.3; 95%CI = 0.2-0.4), high risk level (BC = 1.9; 95%CI =0.4-3.2), weight of complexity (BC = 0.7; 95%CI = 0.5-0.8), and ≥ 4 chronic diseases (BC = 0.7; 95%CI = 0.3-1.1). CONCLUSIONS: In the geriatric population, we found a high number of patients with chronic diseases and there were three levels of risk by AMG with differences in characteristics, morbidity, and use of PC services. The greatest use of services was by patients with older age, high risk level, greater weight of complexity and ≥ 4 chronic diseases. Further research is needed to develop an intervention model more adapted to the reality of the geriatric population based on risk levels by AMG.

[Health services utilization in Primary Care in patients with chronic conditions according to risk levels]. / Utilización de los servicios de salud de Atención Primaria en los pacientes crónicos según nivel de riesgo.

OBJECTIVE: Chronic patients suffer a greater number of health problems and have greater needs for assistance and care. The objective was to describe the use of health services in Primary Care in patients with chronic conditions according to risk level by adjusted morbidity groups (AMG) and analyze the associated factors. METHODS: Cross-sectional study. We included patients ≥18 years-old identified as chronic by the stratification tool according to AMG in a basic health area in the Community of Madrid with an assigned population of 18,107 inhabitants. Sociodemographic, clinical-care and use of services variables were collected and were classified according to the "behavioral" model in predisposing, need or facilitators factors. Univariate, bivariate and multiple linear regression adjusted with robust estimators was performed. RESULTS: 9,443 chronic patients (52.1% of the population in the selected zone) were identified, mean age of 57.8 (SD=18.7); 62.1% women. According to their risk level 4.7% were high risk, 18.7% medium risk and 76.6% low risk. The mean number of contacts per year was 14.1 (SD=15.2); 34.4 (SD=27.9) in high risk; 21.8 (SD=17.2) in medium risk and 10.1 (SD=10.2) in low risk. 7.5 (SD=7.1) contacts were with the doctor and 12.9 (SD=12.9) were face-to-face. The factors associated with higher use of services were high risk (Coefficient B[CB]=12.6; IC95%=11-14.2), immobilization (CB=8.8; IC95%=7.3-10.4), polypharmacy (CB=6; IC95%=5-8.6), female sex (CB=1; IC95%=0.4-1.5), number of chronic diseases (CB=1; IC95%=0.8-1.2) and age (CB=0.03; IC95%=0.01-0.05). CONCLUSIONS: The health services utilization in Primary Care in chronic patients is high and increased according with the risk level by AMG. The contact with the doctor is superior to nurse and the most frequent type is face-to-face. The greater utilization of services responds to predisposing factors (female sex and age) and above all to need factors (high risk, immobility, multimorbidity and polypharmacy).

OBJETIVO: Los pacientes crónicos sufren mayor número de problemas de salud y tienen mayores necesidades de asistencia y cuidados. El objetivo de este estudio fue describir la utilización de servicios de salud de Atención Primaria en los pacientes crónicos según el nivel de riesgo asignado por los grupos de morbilidad ajustados (GMA), así como analizar los factores asociados. METODOS: Se realizó un estudio transversal. Se incluyeron pacientes ≥ 18 años identificados como crónicos por el estratificador GMA en una zona básica de salud de la Comunidad de Madrid, con una población adscrita de 18.107 habitantes. Se recogieron variables sociodemográficas, clínico-asistenciales y de utilización de servicios, y se clasificaron según el modelo "conductual" en "factores predisponentes", "factores de necesidad" o "factores facilitadores". Se empleó un análisis univariado, bivariado y multivariante, ajustando un modelo de regresión lineal múltiple con estimadores robustos. RESULTADOS: Se incluyeron 9.443 pacientes crónicos (el 52,1% de la población de la zona seleccionada), con una edad media de 57,8 años (Desviación estándar [DE]=18,7), siendo mujeres el 62,1%. El 4,7% eran pacientes de alto riesgo, el 18,7% de medio riesgo y el 76,6% presentaba bajo riesgo. La media de contactos/año fue de 14,1 (DE=15,2). 34,4 (DE=27,9) en alto riesgo, 21,8 (DE=17,2) en riesgo medio y 10,1 (DE=10,2) en bajo riesgo. De estos contactos, 7,5 (DE=7,1) fueron con médico y 12,9 (DE=12,9) presenciales. Los factores asociados a mayor utilización fueron el riesgo alto (Coeficiente B [CB]=12,6; IC95%=11,1-14,2), el estar inmovilizado (CB=8,8; IC95%=7,3-10,4), la polimedicación (CB=6; IC95%=5,1-6,9), el ser mujer (CB=1; IC95%=0,4-1,5), el número de enfermedades crónicas (CB=1; IC95%=0,8-1,2) y la edad (CB=0,03; IC95%=0,01-0,05). CONCLUSIONES: La utilización de servicios de Atención Primaria en los pacientes crónicos es elevada y aumenta según el nivel de riesgo asignado por los GMA. El contacto con el médico es superior frente al de la enfermería, y el tipo más frecuente es presencial. La mayor utilización responde a factores predisponentes (ser mujer y la edad) y, sobre todo, de necesidad clínica (alto riesgo, multimorbilidad, polimedicación e inmovilidad).
