Effectiveness of a case management model for people with multimorbidity: Mixed methods study.

A comprehensive and integrated approach to patients with multiple diseases in a health insurance context marked by access barriers and fragmentation of health services. The study provides quantitative and qualitative evidence of the benefits of the case management model in Colombia for patients with multiple diseases and their family caregivers, particularly in terms of the psychosocial dimensions of health-related quality of life and dependence assessment. A significant impact on the caregiver role, as well as an improvement in perception and trust in the health system, was observed as a result of the overcoming of administrative barriers achieved by the nurse case manager. The findings are considered to be extremely useful for decision-makers and insurers in developing a case management model focused on comprehensive and individualized care plans, as well as for individuals with multiple diseases and their caregivers.
