Green LA, Chang HC, Markovitz AR, Paustian ML. The reduction in ED and hospital admissions in medical home practices is specific to primary care–sensitive chronic conditions. Health services research. 2018 Apr;53(2):1163-79.
To determine whether the PCMH transformation reduces hospital and ED utilization, and whether the effect is specific to chronic conditions targeted for management by the PCMH in our setting. Results indicate that PCMH transformation reduces hospital and ED use, and the majority of the effect is specific to PCMH-targeted conditions. Over a 3‐year period, PCMH score was negatively associated with inpatient admissions and ED visits: as PCMH score increased, inpatient admissions and ED visits decreased
by 3.8% and 3.7%, respectively. Patients with chronic conditions had greater reductions (13.9% for inpatient admissions and 11.2% ED visits).
