Design: Stepped wedge, cluster randomised controlled trial over 90 weeks (31 December 2012 - 21 September 2014), with a 54-week pre-trial retrospective data period (start: 19 December 2011) and a 54-week post-trial prospective data collection period (to 4 October 2015).
Participants, setting: Fifteen residential aged care facilities operated by Bupa Aged Care in metropolitan and regional cities in four Australian states.
Intervention: Residential aged care facilities sought to recruit general practitioners as staff members; care staff roles were redefined to allow registered nurses greater involvement in care plan development.
Main (primary) outcome measures: Numbers of falls; numbers of unplanned transfers to hospital; polypharmacy.
Results: The new model of care could be implemented in all facilities, but four could not recruit in-house GPs at any time during the trial period. Intention-to-treat analyses found no statistically significant effect of the intervention on the primary outcome measures. Contamination-adjusted intention-to-treat analyses identified that the presence of an in-house GP was associated with reductions in the numbers of unplanned hospital transfers (incidence rate ratio [IRR], 0.53; 95% CI, 0.43-0.66) and admissions (IRR, 0.52; 95% CI, 0.41-0.64) and of out-of-hours GP call-outs (IRR, 0.54; 95% CI, 0.36-0.80), but also with an increase in the number of reported falls (IRR, 1.37; 95% CI, 1.20-1.58).
Conclusions: Recruiting GPs to work directly in residential aged care facilities is difficult, but may reduce the burden of unplanned presentations to hospitals and increase the reporting of adverse events.
