Efectividad de las intervenciones basadas en telemedicina sobre resultados en salud en pacientes con multimorbilidad en atención primaria: revisión sistemática

OBJECTIVE: To evaluate the effectiveness of telemedicine interventions to improve health outcomes in patients with multiple morbidities in Primary Health Care. DESIGN: A systematic review. DATA SOURCES: INAHTA, Health Guidelines, NICE, Cochrane Library, Medline/PubMed and EMBASE up to April 2018. STUDY SELECTION: Inclusion criteria: patients (adults with 2 or more chronic diseases or a Charlson index greater than three); intervention (telemedicine intervention developed entirely in Primary Health Care); comparator (usual care); health outcomes (mortality, hospital admissions, emergency department visits, health-related quality of life, and satisfaction); study design(clinical practice guideline, systematic review, meta-analysis, randomised controlled clinical trial),and quasi-experimental design). English and Spanish language publication. A total of236 references were located. DATA EXTRACTION: Duplicated articles were removed. Titles, abstracts, and full text of references identified were assessed using the selection criteria; methodological quality assessment; data extraction, and qualitative analysis. RESULTS: Five articles, corresponding to 3 studies, were included, with 2 randomised controlled clinical trials and one quasi-experimental design. No significant results were observed in reducing mortality or improving health-related quality of life. The effectiveness of telemedicine on the number of hospital admissions or emergency visits showed contradictory results. Satisfaction was not measured in the studies included. CONCLUSIONS: The relatively small number of studies, heterogeneity characteristics, and methodological limitations did not confirm the effectiveness of telemedicine intervention on the improvement of mortality, number of hospital admissions, emergency department visits, and health-related quality of life, compared to usual care.
