ABSTRACT
OBJECTIVE:
Practice arrangements in physician offices were characterised by examining the share of visits that involved physician assistants (PAs) and nurse practitioners (NPs). The hypothesis was that collaborative practice (ie, care delivered by a dyad of physician-PA and/or physician-NP) was increasing.DESIGN:
Temporal ecological study.SETTING:
Non-federal physician offices.PARTICIPANTS:
Patient visits to a physician, PA or NP, spanning years 2007-2016.METHODS:
A stratified random sample of visits to office-based physicians was pooled through the National Ambulatory Medical Care Survey public use linkage ï¬le. Among 317 674 visits to physicians, PAs or NPs, solo and collaborative practices were described and compared over two timespans of 2007-2011 and 2012-2016. Weighted patient visits were aggregated in bivariate analyses to achieve nationally representative estimates. Survey statistics assessed patient demographic characteristics, reason for visit and visit specialty by provider type.RESULTS:
Within years 2007-2011 and 2012-2016, there were 4.4 billion and 4.1 billion physician office visits (POVs), respectively. Comparing the two timespans, the rate of POVs with a solo PA (0.43% vs 0.21%) or NP (0.31% vs 0.17%) decreased. Rate of POVs with a collaborative physician-PA increased non-significantly. Rate of POVs with a collaborative physician-NP (0.49% vs 0.97%, p<0.01) increased. Overall, collaborative practice, in particular physician-NP, has increased in recent years (p<0.01), while visits handled by a solo PA or NP decreased (p<0.01). In models adjusted for patient age and chronic conditions, the odds of collaborative practice in years 2012-2016 compared with years 2007-2011 was 35% higher (95% CI 1.01 to 1.79). Furthermore, in 2012-2016, NPs provided more independent primary care, and PAs provided more independent care in a non-primary care medical specialty. Preventive visits declined among all providers.CONCLUSIONS:
In non-federal physician offices, collaborative care with a physician-PA or physician-NP appears to be a growing part of office-based healthcare delivery.Palavras-chave
