Provider practice characteristics that promote interpersonal continuity.

Area of Science:

• Primary Care
• Health Services Research
• Medical Practice Management

Background:

• Patient-centered medical home certification necessitates measuring continuity of care.
• Understanding factors influencing Usual Provider Continuity (UPC) is crucial for improving patient care.
• Interpersonal continuity is a key metric for effective primary care delivery.

Purpose of the Study:

• To investigate the association between provider practice characteristics and interpersonal continuity (UPC).
• To identify modifiable factors influencing continuity of care in primary care settings.
• To compare continuity of care provided by different provider types.

Main Methods:

• Mixed-methods study in 4 university-based family medicine clinics.
• Quantitative analysis of provider performance data (July 2009-June 2010) for 63 primary care providers (PCPs).
• Qualitative validation through provider focus groups using sequential thematic coding.

Main Results:

• Clinic frequency and patient load showed strong linear associations with UPC.
• Clinic frequency, patient load, duration in practice, and provider type explained over 60% of UPC variation.
• Nurse practitioners and physician assistants demonstrated continuity of care comparable to physicians, with higher dependence on clinic frequency.

Conclusions:

• Provider variability in UPC is linked to practice characteristics manageable by practice managers.
• Interpersonal continuity can be enhanced by optimizing clinic frequency and patient load.
• Nurse practitioners and physician assistants offer similar continuity of care as physicians, supporting team-based care models.
