New Metric Determines Adequacy of VA Primary Care Staffing


BACKGROUND:
Improving patient access to care necessitates balancing patient demand with provider availability. "Panel size" (i.e., the number of patients a primary care provider (PCP) is responsible for), is associated with patient satisfaction, provider burnout, clinical quality, access, and efficiency. In VA primary care (PC), PCPs lead four-person Patient Aligned Care Teams (PACTs) that include a nurse care manager, a clinical associate, and an administrative clerk. PACTs have a panel size of 1,200 patients per 1.0 full-time equivalent (FTE) physician-led team and 900 patients per 1.0 FTE APP (Advanced Practice Provider)-led team. This study created a PCP staffing measure using clinic-level provider FTE and number of assigned patients to identify PC clinics at risk of insufficient staffing and describe rural-urban staffing variation. Using VA administrative data from 2017-2021, investigators created the following equation to calculate a monthly gap-staffing metric in 916 VA PC clinics.
Gap Staffing Metric

FINDINGS:

  • Over the 3.5-year study period at the 916 clinics, 38 (4%) were always under-staffed, 21 (2%) were always marginally staffed, and 200 (22%) were always fully staffed.
  • At the end of the study period (March 2021), 351 PC clinics (39%) were not fully staffed and 179 of these clinics (51%) had a gap of at least 0.5 APP FTE, representing a potential minimum threshold for hiring a new provider. But 559 clinics were fully staffed with excess clinic capacity of 11-15%.
  • Depending how FTE is distributed (e.g., across clinics vs. within each clinic) and the provider type, 228 to 521 PCP FTE are needed to fully staff all PC clinics as of March 2021. This represents a 4-8% provider staffing deficit.
  • Over the entire study period, rural clinics, on average, were under-staffed for 21% of months compared to 14% of months for urban clinics, a 50% higher rate.

IMPLICATIONS:

  • The gap staffing metric may be a beneficial tool to identify PC clinics that are persistently over- or under-staffed, facilitating strategic workforce planning and allowing better distribution of provider FTE to address patient care needs.

LIMITATIONS:

  • Calculations used in this study depended on data accuracy, including VA provider FTE and assigned patient data.

What are HSR&D Publication Briefs?

HSR&D requires notification by HSR&D-funded investigators about all articles accepted for publication. These journal articles are reviewed by HSR&D and publication briefs or summaries are written for a select number of articles that are then forwarded to VHA Central Office leadership to keep them informed about important findings or information. Articles to be summarized are selected by HSR&D based on timeliness of the findings, interest of leadership, or potential impact on the organization. Publication briefs are written for only a small number of HSR&D published articles. Visit the HSR&D citations database for a complete listing of HSR&D articles and presentations.
