Cambios en el modelo de atención de personas con multimorbilidad crónica: una revisión narrativa / Changes in the care model of people with chronic multimorbidity: a narrative review

Introducción: Muchos países deben enfrentarse al rápido aumento de personas viviendo con alguna condición crónica de salud. En Chile, según datos entregados por la última encuesta nacional de salud, se ha estimado que la población con alguna condición crónica es de 11 millones de personas, de las cuales un 81% presenta multimorbilidad. Este grupo tiene una menor calidad de vida, una mayor mortalidad ajustada por edad, mayor utilización de recursos del sistema de salud, así como un mayor riesgo de hospitalización y una estadía hospitalaria más prolongada. Metodología: revisión narrativa de la literatura para lograr identificar como se ha organizado el cuidado de los pacientes con multimorbilidad a lo largo del tiempo y como se han ido desarrollando estrategias que buscan un abor-daje distinto. Resultados: los sistemas de salud se han organizado con un enfoque centrado en la enfermedad, lo que genera que los pacientes reciban un cuidado fragmentado, ineficiente e inefectivo, sin lograr dimensionar la complejidad de la persona y su contexto biopsicosocial. Los sistemas de salud, principalmente en Europa han desarrollado diversas iniciativas que buscan cambiar la perspectiva desde el cuidado centrado en la enfermedad al cuidado centrado en la persona Conclusiones: se puede concluir que la multimorbilidad es un problema que afecta a millones de personas en el mundo y que los servicios y sistemas de salud necesitan hacer un cambio hacia un modelo centrado en la persona de forma de dar respuestas a las necesidades de este grupo de pacientes.

Red Europea de Seguridad del Paciente y Calidad (Eupean Network for Patient Safety and Quality of Care). Desarrollo y resultados preliminares en Europa y en el Sistema Nacional de Salud / European Union Network for Patient Safety and Quality of Care (PASQ). Development and preliminary results in Europe and in the Spanish National Health System

Antecedentes: La acción cooperativa conocida como European Union Network for Patient Safety and Quality of Care (PaSQ) pretende promover la seguridad del paciente (SP) en la Unión Europea (UE) y facilitar el intercambio de experiencias entre los Estados Miembros y otras organizaciones interesadas en aspectos relacionados con la calidad asistencial (CA), la SP y la participación de los pacientes. En este artículo se presentan el desarrollo y los resultados preliminares de esta iniciativa, especialmente en el Sistema Nacional de Salud español (SNS). Desarrollo y metodología de trabajo: PaSQ se desarrolló a través de 7 paquetes de trabajo, liderados por diferentes países, que estaban orientados prioritariamente a: a) el intercambio de buenas prácticas sobre CA y SP que habían sido identificadas a través de cuestionarios específicos y seleccionadas a través de criterios explícitos consensuados, y b) la implementación de prácticas clínicas seguras (PCS) de comprobada efectividad, acordadas por los Estados Miembros de la Unión Europea. Evolución de la acción cooperativa: Se identificaron 482 buenas prácticas (39% remitidas por profesionales españoles). Se realizaron un total de 34 eventos en la UE, 11 con participación española, que permitieron compartir algunas de estas buenas prácticas. Un total de 194 centros sanitarios (49% españoles) están implementando las 4 PCS acordadas (higiene de manos, cirugía segura, conciliación de la medicación y escala de detección temprana de deterioro clínico en pediatría). Logros alcanzados y perspectivas futuras: PaSQ está facilitando reforzar la colaboración entre organizaciones y profesionales a nivel de la UE y del SNS en torno a la SP y la CA (AU)

Background: The joint action, European Union Network for Patient Safety and Quality of Care: PaSQ, aims to promote patient safety (PS) in the European Union (EU) and to facilitate the exchange of experiences among Member States (MS) and stakeholders on issues related to quality of care, PS, and patient involvement. The development and preliminary results are presented here, especially as regards the Spanish National Health System (SNHS). Development and methodology: PaSQ is developed through 7 work packages, primarily aimed at sharing good practices (GP), which were identified using specific questionnaires and selected by means of explicit criteria, as well as to implement safe clinical practices (SCP) of proven effectiveness and agreed among MS. Evolution of the joint action: A total of 482 GP (39% provided by Spanish professionals) were identified. The 34 events organised in the EU, 11 including Spanish participation, facilitate sharing these practices. A total of 194 Health Care centres (49% in Spain) are implementing SCP (hand hygiene, safe surgery, medication reconciliation, and paediatric early warning scores). Achievements and future perspectives: PaSQ is making it possible to strengthen collaboration between organizations and professionals at EU and SNHS level regarding PS and quality of care (AU)

Prevalence of adverse events in the hospitals of five Latin American countries: results of the 'Iberoamerican Study of Adverse Events' (IBEAS).

BACKGROUND: Interest in patient safety (PS) is growing exponentially, fuelled by epidemiological research unveiling the extent of unsafe care. However, there is little information about the frequency of harm in developing and transitional countries. To address this issue, the authors performed a study known as the Iberoamerican Adverse Event Study, through a collaborative between the governments of Argentina, Colombia, Costa Rica, Mexico and Peru, the Spanish Ministry of Health, Social Policy and Equality, the Pan American Health Organization and the WHO Patient Safety. METHODS: The study used a cross-sectional design, involving 58 hospitals in the five Latin American countries, to measure the point prevalence of patients presenting an adverse event (AE) on the day of observation. All inpatients at the time of the study were included. RESULTS: A total of 11 379 inpatients were surveyed. Of these, 1191 had at least one AE that the reviewer judged to be related to the care received rather than to the underlying conditions. The estimated point prevalence rate was 10.5% (95% CI 9.91 to 11.04), with more than 28% of AE causing disability and another 6% associated with the death of the patient. Almost 60% of AE were considered preventable. CONCLUSIONS: The high rate of prevalent AE found suggests that PS may represent an important public-health issue in the participating hospitals. While new studies may be needed to confirm these results, these may already be useful to inspire new PS-improvement policies in those settings.

Diseño del estudio IBEAS: prevalencia de efectos adversos en hospitales de Latinoamérica / IBEAS design: adverse events prevalence in Latin American hospitals

Objetivos. Describir las características y metodología del estudio IBEAS: prevalencia de efectos adversos en hospitales de Latinoamérica, que persigue realizar una aproximación a la magnitud, trascendencia e impacto de los eventos adversos (EA); identificar áreas y problemas prioritarios de la seguridad del paciente; incrementar la masa crítica de profesionales involucrados en la seguridad del paciente e incorporar a la agenda de los países objetivos y actividades para mejorar la seguridad del paciente. Método. Estudio sobre la seguridad de los pacientes. Ámbito: 35 hospitales de 5 países: Argentina, Colombia, Costa Rica, México y Perú, a través del análisis de los efectos adversos identificados. Diseño de prevalencia utilizando la revisión de la historia clínica. Resultados. Se describen las implicaciones en el uso del diseño transversal en el estudio de EA, tanto en los recursos necesarios como en la validez interna y en la utilidad para la gestión de riesgos sanitarios. Conclusiones. El diseño transversal es eficiente en tiempo y recursos y fácil de realizar, y aunque no permite estudiar la totalidad del episodio de hospitalización, ha demostrado ser capaz para sostener un sistema de vigilancia. Debido a un posible sesgo de supervivencia, los EA que ocasionen un ingreso se verán sobrerrepresentados, y también aquellos relacionados con la infección nosocomial o los que sean difícilmente identificables si no se ve al paciente. La comunicación con el personal de planta (mientras el paciente está hospitalizado) favorece el juicio de la causalidad del efecto adverso y de su evitabilidad(AU)

Objectives. To describe the methodological characteristics of the IBEAS study: adverse events prevalence in Latin American hospitals, with the aim of analysing the magnitude, significance and impact of adverse events (AE); to identify the main problems associated with patient safety AE; to increase the capacity of professionals involved in patient safety; and the setting up of patient safety agendas in the participating countries. Methods. A patient safety study launched in 35 Latin American hospitals through the analysis of AE in 5 countries: Argentina, Colombia, Costa Rica, Mexico and Peru, using a cross-sectional study using a review of clinical records as the main method. Results. The implications of using a cross-sectional design when studying AE are described, in terms of resources required, internal validity and usefulness related to risk management. Conclusions. The cross-sectional design seems an efficient methodology in terms of time and resources spent, as well as being easy to carry out. Although the cross-sectional design does not review the all hospital episodes, it is able to provide a reliable estimate of prevalence and to support a surveillance system. Because of a possible survival bias, it is likely that the AE which led to hospital admissions will be overestimated, as well as the health related infections or those adverse events which are difficult to identify if the patient is not examined (e.g. contusions). Communication with the ward staff (if the patient is still hospitalised) help in finding the causality and their prevention(AU)

Prevención de la bacteriemia relacionada con catéteres en UCI mediante una intervención multifactorial. Informe del estudio piloto / Prevention of bacteriema related with ICU catheters by multifactorial intervention: A report of the pilot study

Objetivo: Evaluar la aplicabilidad a nivel nacional de las intervenciones propuestas en el estado de Michigan por Peter Pronovost et al para la prevención de B-CVC en pacientes ingresados en UCI. Diseño: Estudio piloto, prospectivo y comparativo. Ámbito: Han participado 18 UCI (nueve control y nueve intervención) de tres comunidades autónomas de España a lo largo de tres meses en el año 2007. Intervención Incluyó las actividades siguientes: a) programa de formación del personal sanitario; b) introducción de medidas específicas relacionadas con la inserción y manejo de los CVC (lista de comprobación durante la inserción de los CVC, carro exclusivo para accesos venosos, cartel informativo con los cinco procedimientos propuestos para disminuir las bacteriemias: higiene de manos, uso de barreras asépticas máximas durante la inserción, asepsia de la piel del punto de inserción con clorhexidina, evitar la vía de acceso femoral y retirar todos los CVC innecesarios, y c) medidas dirigidas a promover la cultura de seguridad en el trabajo diario (objetivos diarios, aprender de los errores, rondas de seguridad). Resultados: La tasa de B-CVC expresada en medias ha disminuido a la mitad en comparación con los registros históricos. Se identificaron diferentes problemas en la implantación de las medidas específicas relacionadas con los catéteres y en las herramientas de seguridad. Conclusiones: El proyecto de intervención evaluado en el estudio piloto puede ser viable a nivel nacional. Es necesario modificar y adaptar a la realidad española las herramientas propuestas (AU)

Objective: To assess the applicability on a national level of the interventions proposed by Peter Pronovost et al in Michigan state for the prevention of central vascular catheter-related bacteremia (B-CVC) in patients admitted to the ICU. Design: Pilot, prospective and comparative study. Setting: Eighteen ICUs (9 control and 9 intervention) from three autonomous communities in Spain during 3 months in 2007 participated in the study. Intervention: The following activities were included: a) training program for health care personnel, b) introduction of specific measures related to the insertion and care of CVC (catheter insertion checklist, basic recommendations for maintenance of central catheters, dedicated cart for venous accesses, information poster with the five procedures proposed to reduce bacteremias: hands hygiene, use of maximal aseptic barriers during insertion, asepsis of the skin at the insertion point with chlorhexidine, avoidance of the femoral access, and removal of all CVC) and c) measures aiming to promote the culture of safe daily work (daily objectives, learning from mistakes, safety rounds). Results: The rate of B-CVC expressed as mean values has shown a half reduction as compared with historical registers. Different problems in the implementation of specific measures related to catheters and safety tools were identified. Conclusions: The intervention project assessed in the pilot study may be viable on the national level. It is necessary to modify and adapt to the Spanish reality the interventions proposed (AU)

A prospective randomized comparison of laparoscopic appendectomy with open appendectomy: Clinical and economic analyses.

BACKGROUND: Previous randomized studies of laparoscopic appendectomy produced conflicting recommendations, and the adequacy of sample sizes is generally unknown. We compared clinical and economic outcomes after laparoscopic and open appendectomy in a sample of predetermined statistical power. METHODS: A pre-study power analysis suggested that 200 randomized patients would yield 80% power to show a mean decrease of 1.3 days' hospitalization. One hundred ninety-eight patients with a preoperative diagnosis of acute appendicitis were randomized prospectively to laparoscopic or open appendectomy. Economic analysis included billed charges, total costs, direct costs, and indirect costs associated with treatment. RESULTS: Laparoscopic appendectomy took longer to perform than open appendectomy (median, 107 vs 91 minutes; P <.01) and was associated with fewer days to return to a general diet (mean, 1.6 versus 2.3 days; P <.01), a shorter duration of parenteral analgesia (mean, 1.6 versus 2.2 days; P <.01), fewer morphine-equivalent milligrams of parenteral narcotic (median, 14 mg versus 34 mg; P =.001), a shorter postoperative hospital stay (mean, 2.6 versus 3.4 days; P <.01), and earlier return to full activity (median, 14 versus 21 days; P <.02). However, operative morbidity and time to return to work were comparable. Billed charges and direct costs were not significantly different in the 2 groups ($7711 versus $7146 and $5357 versus $4945, respectively), but total costs (including indirect costs) of laparoscopic appendectomy were, on average, nearly $2400 less, given the shorter length of stay and abbreviated recuperative period ($11,577 versus $13,965). Subgroup analyses suggested the benefit of a laparoscopic approach for uncomplicated appendicitis and for patients with active lifestyles. CONCLUSIONS: While laparoscopic appendectomy is associated with statistically significant but clinically questionable advantages over open appendectomy, a laparoscopic approach is relatively less expensive. The estimated difference in total costs of treatment (direct and indirect costs) was at least $2000 in more than 60% of the bootstrapped iterations. The economic significance and implications favoring a laparoscopic approach cannot be ignored.

Trauma in pregnancy.

OBJECTIVE: To determine whether the severity of maternal injury or other maternal and fetal variables will predict the outcome of pregnancy in the injured pregnant patient. PATIENTS AND METHODS: In this retrospective review of pregnant patients hospitalized at a level 1 trauma center from 1986 to 1996, we analyzed the maternal Injury Severity Score, maternal mortality, fetal-neonatal mortality, maternal hypotension, and fetal heart rate. RESULTS: Sixty-one pregnant women were identified who were hospitalized after trauma. The mean +/- SD maternal age was 26.6 +/- 6.6 years. The distribution of trauma per gestational age was 21%, 20%, and 59% for the first, second, and third trimester, respectively. The most common mechanism of injury was motor vehicle crashes. Long-term pregnancy outcome was available in 53 patients (87%). There was 1 maternal death. Fetal-neonatal death occurred in 8 (15%) of 53 pregnancies. Most maternal physiologic variables were not predictors of pregnancy outcome. We were unable to detect a difference in the distribution of Injury Severity Scores between viable and nonviable pregnancies. However, maternal hypotension and low fetal heart rate were common in nonviable pregnancies (P = .02). CONCLUSIONS: Maternal hypotension and fetal heart rate are potential predictors of pregnancy outcome after trauma. Other maternal and fetal physiologic variables are poor measures of fetal well-being and are unable to predict fetal outcome. Fetal-neonatal death does not necessarily correlate with severity of maternal injury.

Death related to propofol use in an adult patient.

OBJECTIVE: To report an adult trauma patient fatality related to propofol administration. DESIGN: Retrospective case review. SETTING: Trauma intensive care unit (ICU) in a level one trauma center. PATIENT: An 18-yr-old man involved in a motor vehicle crash. INTERVENTIONS: Treatment for multiple trauma injuries and propofol sedation. MEASUREMENTS AND MAIN RESULTS: Posttrauma ICU monitoring was performed. The patient developed cardiac arrhythmia, metabolic acidosis, and cardiac failure, which resulted in death. CONCLUSION: Death related to propofol infusion can occur in adults as well as in pediatric patients.

Management of necrotizing pancreatitis by repeated operative necrosectomy using a zipper technique.

METHODS: From 1983 to 1995, 72 patients with necrotizing pancreatitis were treated with a general approach involving planned reoperative necrosectomies and interval abdominal wound closure using a zipper. RESULTS: Hospital mortality was 25%. Multiple organ failure without sepsis caused early mortality in 3 of 4 patients and sepsis caused late mortality in 11 of the remaining 14. The mean number of reoperative necrosectomies/debridements was 2 (0 to 7). Fistulae developed in 25 patients (35%); 64% were treated conservatively. Recurrent intraabdominal abscesses developed in 9 patients (13%) but were drained percutaneously in 5. Hemorrhage required intervention in 13 patients (18%). Prognostic factors included APACHE-II score on admission < 13 (P = 0.005), absence of postoperative hemorrhage (P = 0.01), and peripancreatic tissue necrosis alone (P < 0.05). CONCLUSIONS: The zipper approach effectively maximizes the necrosectomy and decreases the incidence of recurrent intraabdominal infection requiring reoperation. APACHE-II score > or = 13, extensive parenchymal necrosis, and postoperative hemorrhage signify worse outcome.

Serosurveillance of susceptibility to rubella in a Mexican female group.

The susceptibility to rubella of a group of Mexican females of childbearing age was determined. Members of the group were selected based on the highest probability of having been exposed to the virus they were older than 15, and from a low socio-economic urban stratum. Anti-viral antibodies were determined by hemagglutination inhibition. Concentration was expressed as International Units of IgG anti-rubella hemagglutinin (IU). Antibody concentrations lower than 15.6 IU/ml were regarded as non-protective. A 16% susceptibility was found.

Purification of rubella virus by isopycnic gradients: continuous Percoll versus discontinuous sucrose.

Concentrated viral suspensions were purified by isopycnic gradients: discontinuous sucrose, continuous Percoll. With Percoll, homogenous buoyant density virus were obtained; hemagglutinating titer, concentration factor, specific activity, and reproducible yield were higher than with sucrose.

Quantitation of rubella virus by competitive enzyme immunosorbent assay.

A simple and rapid technique for quantification of rubella virus is described. The specificity of the competitive enzyme linked immunosorbent assay (ELISA) was quantified by comparing the slopes and the Y intercepts of the curves obtained when viral antigen vs. control antigen was used. The curves were derived by plotting the absorbance ratio against the logarithm of the antigen concentration. The technique was reproducible, its sensitivity depending on the purity of the antigen used. In ELISA, when an antigen precipitated by ammonium sulfate was used, the sensitivity expressed in protein/ml was 7 micrograms and when an antigen purified by sucrose gradient was used, 70 ng, whereas the limit of sensitivity in the standard technique of hemagglutination was only 38 micrograms.
