Trends in full-time working in general practice: a repeated cross-sectional study.

Abstract

There is little evidence and no agreement on what constitutes full-time working for GPs. This is essential for workforce planning, resource allocation, and accurately describing GP activity. To clarify the definition of full-time working for GPs, how this has changed over time, and whether these changes are explained by GP demographics. Data were obtained from repeated cross-sectional national surveys for GPs, which were conducted between 2010 and 2021. A comparison was undertaken of three measures of working time commitments (hours and sessions per week and hours per session) plus a measure of workload intensity across survey years. Multiple regression was used to adjust the changes over time for age, sex, ethnicity, contract type, area deprivation, and rurality. Unadjusted hours and sessions per week were compared with definitions of full-time working. Average hours and sessions per week reduced from 40.5 (95% confidence interval [CI] = 38.5 to 42.5) to 38.0 (95% CI = 36.3 to 39.6) and 7.3 (95% CI = 7.2 to 7.3) to 6.2 (95% CI = 6.2 to 6.3) between 2010 and 2021, respectively. In 2021, 54.6% of GPs worked at least 37.5 hours per week and 9.5% worked at least nine sessions. Hours per session increased from 5.7 (95% CI = 5.7 to 5.7) to 6.2 (95% CI = 6.2 to 6.3) between 2010 and 2021. Partners worked more hours, sessions, and hours per session. Adjustments expanded the increase in hours per session from 0.54 to 0.61. At the current average duration of sessions, six sessions per week aligns with the NHS definition of full-time hours. However, hours per week is a more consistent way to define full-time work for GPs.
