PurposeChronic diseases such as hypertension, diabetes mellitus, and hyperlipidemia are public health concerns. However, little is known about how these affect patient-level health measures. The aim of the study was to examine the impact of a chronic care model (CCM) on the participant’s health-related quality of life (QoL).Patients and methodsParticipants received either usual care or CCM by a team of health care professionals including pharmacists, nurses, dietitians, and general practitioners. The participants in the intervention group received medication counseling, adherence, and dietary advice from the health care team. The QoL was measured using the EQ-5D (EuroQoL-five dimension, health-related quality of life questionnaire) and comparison was made between usual care and intervention groups at the beginning and end of the study at 6 months.ResultsMean (standard deviation) EQ-5D index scores improved significantly in the intervention group (0.92±0.10 vs 0.95±0.08; P≤0.01), but not in the usual care group (0.94±0.09 vs 0.95±0.09; P=0.084). Similarly, more participants in the intervention group reported improvements in their QoL compared with the usual care group, especially in the pain/discomfort and anxiety/depression dimensions.ConclusionThe implementation of the CCM resulted in significant improvement in QoL. An interdisciplinary team CCM approach should be encouraged, to ultimately result in behavior changes and improve the QoL of the patients.
