Randomized Controlled Trial Multicenter Study
The effect of guided care teams on the use of health services: results from a cluster-randomized controlled trial.
The effect of interdisciplinary primary care teams on the use of health services by patients with multiple chronic conditions is uncertain. This study aimed to measure the effect of guided care teams on multimorbid older patients' use of health services. ⋯ Guided care reduces the use of home health care but has little effect on the use of other health services in the short run. Its positive effect on Kaiser-Permanente patients' use of skilled nursing facilities and other health services is intriguing. Trial Registration clinicaltrials.gov Identifier: NCT00121940.
