Primary care team and its association with quality of care for people with multimorbidity: a systematic review.

Abstract

Multimorbidity is posing an enormous burden to health systems, especially for primary healthcare system. While primary care teams (PCTs) are believed to have potentials to improve quality of primary health care (PHC), less is known about their impact on the quality of care for people with multimorbidity. We assessed the characteristics of PCTs and their impact on the quality of care for people with multimorbidity and the mechanisms.  METHODS: We searched PubMed, MEDLINE, EMBASE, ProQuest for published studies from January 2000 to October 2021 for studies in English. Following through PRISMA guidelines, two reviewers independently abstracted data and reconciled by consensus with a third reviewer. Titles, abstracts, and full texts were evaluated to identify relevant studies. Studies were categorized by types of interventions, the impact of interventions on outcome measures, and mechanisms of interventions.  RESULTS: Seventeen studies (13 RCT, 3 cohort studies, and 1 non-randomized trial) were identified. PCTs were summarized into three types-upward PCTs, downward PCTs and traditional PCTs according to the skill mix. The upward PCTs included primary care workers and specialists from upper-level hospitals, downward PCTs involving primary care workers and lay health workers, and traditional PCTs involving physicians and care managers. PCTs improved patients' mental and psychological health outcomes greatly, and also improved patients' perceptions towards care including satisfaction with care, sense of improvement, and patient-centeredness. PCTs also improved the process of care and changed providers' behaviors. However, PCTs showed mixed effects on clinical outcome measures. PCTs have improved mental and psychological health outcomes, the process of care, patients' care experiences, and satisfaction towards care for patients with multimorbidity. The effect of PCTs on clinical outcomes and changes in patient behaviors need to be further explored.
