Who Should Deliver Primary Care in Long-term Care Facilities to Optimize Resident Outcomes? A Systematic Review

Objective: Across the world, health care for residents in long-term care facilities (LTCFs) is provided by a range of different professionals, and there is no consensus on which professional group(s) deliver the best outcomes for residents. The objective of this review is to investigate how the health outcomes of older adults in LTCFs vary according to which professional group(s) provides first-line medical care.

Design: A systematic review and narrative synthesis were performed. Medline, Embase, the Cochrane Central Register of Controlled Trials, and Scopus were searched for studies from high-income countries, of any design, published after 2000. Quality was assessed using the Cochrane Risk of Bias and ROBINS-I tools. The exposure of interest was the professional group(s) involved in the delivery of first-line primary care.

Setting and participants: Older adults living in LTCFs.

Measures: The principal outcomes were unplanned transfer to hospital, prescribing quality, and mortality.

Results: Searches identified 10,532 citations after removing duplicates. Twenty-six publications (across 24 studies) met the inclusion criteria. A narrative synthesis was conducted of the 20 experimental and 4 observational studies, involving approximately 98,000 residents. Seven studies were set in the USA, 6 in Australia, 3 in Canada, 2 in New Zealand, and 6 in European countries. Interventions were varied, complex and multi-faceted. Nineteen interventional studies, including 4 randomized trials, involved the addition of a specialist practitioner, either a doctor or nurse, to supplement usual primary care. The most commonly reported outcomes were unplanned hospital transfer and prescribing quality. Interventions based on specialist nurses were associated with reductions in unplanned hospital transfers in 10 out of 12 publications. There was no consistent evidence of a positive impact of specialist doctor interventions on unplanned hospital transfers. However, specialist doctors were associated with improvements in prescribing quality in all 7 relevant studies. There was a paucity of evidence on the impact of specialist nurse interventions on prescribing, and of specialist practitioners on mortality, and no improvements were reported.

Conclusions: Addition of specialist doctors or nurses to the first-line medical team has the potential to improve key health outcomes for residents in LTCFs.
