Abstract

Health systems face multimorbidity as the leading cause of the burden of disease and demand for healthcare services. Although non-communicable diseases are well known, and countries in Latin America have implemented strategies to its approach, tackling multimorbidity is still a challenge and an emerging topic. In response to this, Centro de Innovación en Salud ANCORA UC, in association with Servicio de Salud Metropolitano Sur Oriente and the National Health Fund, implemented a pilot study a Multimorbidity Patient-Centered Care Model in the health network. The objective was to evaluate the health care services utilization and mortality. The authors performed a cohort study with adults with non-communicable diseases, stratified by ACG® System. Analysis used logistic regression, adjusted by confounding variables. The intervened group had a significantly lower incidence of hospital admissions, length of stay, number of consultancies to hospital emergency, and number of consultancies to primary care emergency than the control group. Further, it was associated with significantly less mortality (OR 0.54; 95% CI 0.47 – 0.63). Barriers and facilitators proper from a complex intervention were approached. The model showed positive results in mortality and health services utilization. A description is provided to contribute to this emerging topic and facilitate its reproducibility.

Key words: Multimorbidity, patient-centered care, risk stratification, impact analysis.
