Summary

Increased availability of family and general practice physicians is linked to fewer hospitalizations for avoidable conditions. This suggests family physicians improve primary care access and reduce preventable admissions.

Area of Science:

  • Health Services Research
  • Public Health Policy
  • Primary Care Medicine

Background:

  • Avoidable hospitalizations (AHCs) indicate population-level healthcare access.
  • Primary care physician availability is a potential determinant of AHC rates.

Purpose of the Study:

  • To investigate the association between primary care physician supply and AHC rates in Pennsylvania.
  • To determine if physician type influences avoidable hospitalization rates.

Main Methods:

  • Analysis of statewide hospital discharge data for age- and sex-adjusted AHC rates across 26 health service areas (HSAs).
  • Correlation analysis of physician numbers (family/general practice, general internal medicine, general pediatrics) and per capita income with AHC rates.

Main Results:

  • Higher numbers of family and general practice physicians (FPs/GPs) per capita correlated with lower adult and pediatric AHC rates.
  • This association persisted after controlling for per capita income.
  • No significant correlation was found between general internists/pediatricians and AHC rates.

Conclusions:

  • FP/GP availability is associated with reduced hospitalizations for specific conditions.
  • Family physicians may offer superior first-contact healthcare access compared to internists or pediatricians in Pennsylvania.
  • Further research is warranted on the cost-effectiveness of family physician care in reducing AHCs.
