Patient-centered medical home implementation effects on emergency room utilization: a case study.

Area of Science:

• Health Services Research
• Primary Care Models
• Healthcare Delivery Systems

Background:

• The Patient-Centered Medical Home (PCMH) is a healthcare model aimed at improving primary care access, quality, and outcomes.
• While PCMH benefits like reduced emergency room (ER) visits are noted, empirical evidence on its effectiveness is still developing.
• The Military Health System implemented PCMHs, necessitating evaluation of their impact.

Purpose of the Study:

• To evaluate the effectiveness of a Patient-Centered Medical Home (PCMH) implemented by the Army Medical Command in reducing emergency room (ER) visits.
• To compare ER visit rates between PCMH enrollees and standard primary care clinic enrollees.

Main Methods:

• A quasi-experimental study was conducted at Ft. Campbell, Kentucky, comparing ER visits of PCMH enrollees to standard care enrollees.
• Statistical analysis controlled for demographic factors (age, gender, race, beneficiary category, marital status) and healthcare utilization (outpatient visits).

Main Results:

• PCMH enrollees were 67% less likely to visit the ER compared to standard care enrollees, after controlling for covariates.
• Men were significantly less likely to visit the ER than women within the PCMH population.
• High outpatient users were more likely to visit the ER, regardless of care model.

Conclusions:

• The findings provide empirical support for the PCMH model's effectiveness in reducing ER utilization within the Military Health System.
• The PCMH model shows promise for enhancing primary care delivery and potentially lowering healthcare costs.
• Further research is recommended to explore limitations and long-term impacts of PCMH implementation.
