Effectiveness of an intervention for improving drug prescription in primary care patients with multimorbidity and polypharmacy:Study protocol of a cluster randomized clinical trial (Multi-PAP project)

This study was funded by the Fondo de Investigaciones Sanitarias ISCIII (Grant Numbers PI15/00276, PI15/00572, PI15/00996), REDISSEC (Project Numbers RD12/0001/0012, RD16/0001/0005), and the European Regional Development Fund ("A way to build Europe").Background: Multimorbidity is associated with negative effects both on people's health and on healthcare systems. A key problem linked to multimorbidity is polypharmacy, which in turn is associated with increased risk of partly preventable adverse effects, including mortality. The Ariadne principles describe a model of care based on a thorough assessment of diseases, treatments (and potential interactions), clinical status, context and preferences of patients with multimorbidity, with the aim of prioritizing and sharing realistic treatment goals that guide an individualized management. The aim of this study is to evaluate the effectiveness of a complex intervention that implements the Ariadne principles in a population of young-old patients with multimorbidity and polypharmacy. The intervention seeks to improve the appropriateness of prescribing in primary care (PC), as measured by the medication appropriateness index (MAI) score at 6 and 12months, as compared with usual care. Methods/Design: Design:pragmatic cluster randomized clinical trial. Unit of randomization: family physician (FP). Unit of analysis: patient. Scope: PC health centres in three autonomous communities: Aragon, Madrid, and Andalusia (Spain). Population: patients aged 65-74years with multimorbidity (≥3 chronic diseases) and polypharmacy (≥5 drugs prescribed in ≥3months). Sample size: n=400 (200 per study arm). Intervention: complex intervention based on the implementation of the Ariadne principles with two components: (1) FP training and (2) FP-patient interview. Outcomes: MAI score, health services use, quality of life (Euroqol 5D-5L), pharmacotherapy and adherence to treatment (Morisky-Green, Haynes-Sackett), and clinical and socio-demographic variables. Statistical analysis: primary outcome is the difference in MAI score between T0 and T1 and corresponding 95% confidence interval. Adjustment for confounding factors will be performed by multilevel analysis. All analyses will be carried out in accordance with the intention-to-treat principle. Discussion: It is essential to provide evidence concerning interventions on PC patients with polypharmacy and multimorbidity, conducted in the context of routine clinical practice, and involving young-old patients with significant potential for preventing negative health outcomes.

Traducción al español y validación del cuestionario de retroalimentación en educación médica (FEEDME-Cultura) durante rotaciones clínicas

Introducción: El cuestionario Cultura de retroalimentación en educación médica es una escala validad que determina la percepción de la cultura de retroalimentación en países de habla inglesa. El objetivo de este trabajo es validar este cuestionario en su versión espanola ̃ en estudiantes de medicina peruanos durante una rotación clínica. Métodos: Un estudio observacional, analítico de tipo instrumental fue realizado en 139 estu- diantes de medicina. La validez de la escala fue determinada por V-de-Aiken e intervalos de confianza. Se realizaron pruebas de análisis factorial y alfa de Cronbach. Resultados: Todos los valores fueron estadísticamente significativos cuando se evaluaron con el coeficiente V-de-Aiken. Además, la asimetría y curtosis de todos los ítems son adecuados ya que no exceden el rango >± 1.5. La significancia de la prueba de esfericidad de Barlett (1521.8; gl = 120; p = 0.001) y el coeficiente Kaiser Meyer-Olkin (KMO= .953) fueron adecuados y el análisis factorial exploratorio reveló una estructura de dos factores. El coeficiente de Cronbach de la escala total y sus factores, fue superior a 0,80. Conclusiones: El cuestionario Cultura de retroalimentación en educación médica en espanol ̃ es una escala válida para evaluar la percepción sobre la cultura de retroalimentación en estudi- antes de medicina que están realizando rotación clínica

Resultados da cirurgia de catarata em pacientes diabéticos : resultados do Pan-American Collaborative Retina Study Group

Purpose: This study was designed to evaluate the visual and anatomical outcomes after cataract surgery in diabetic patients with different intraoperative therapeutic strategies. Methods: The research design comprised of a multicentric, retrospective, interventional study conducted at 6 centers in Argentina, Brazil, Costa Rica, Puerto Rico, Spain, and Venezuela. We included 138 diabetic patients with at least 6-month follow-up following phacoemulsification and intraocular lens implantation. Best-corrected visual acuity (BCVA) and central subfield thickness were collected at baseline and at 1-, 2-, 3-, and 6-month follow-up. Of these, 42 cases were not treated with any intraoperative coadjuvant medication (Group 1), 59 patients received intraoperative bevacizumab (Group 2) and 37 patients received intraoperative triamcinolone (4 mg/0.1 ml) (Group 3). Results: The mean logMAR [± standard deviation (SD)] BCVA improved from 0.82 (± 0.43) at baseline, to 0.14 (± 0.23) at 6-month follow-up (p<0.001) in Group 1; from 0.80 (± 0.48) to 0.54 (± 0.45) (p<0.001) in Group 2; and from 1.0 (± 0.40) to 0.46 (± 0.34) (p<0.001) in Group 3. The mean central subfield thickness increased from 263.57 μm (± 35.7) at baseline to 274.57 μm (± 48.7) at 6-month follow-up (p=0.088) in Group 1; from 316.02 μm (± 100.4) to 339.56 μm (± 145.3) (p=0.184) in Group 2; and from 259.18 μm (± 97.9) to 282.21 μm (± 87.24) (p=0.044) in Group 3. Conclusions: Diabetic patients may significantly benefit from cataract surgery. This study provides evidence to support the use of intravitreal triamcinolone or bevacizumab at the time of cataract surgery in cases with pre-existent diabetic macular edema or moderate-severe non-proliferative diabetic retinopathy
