Evaluating the Effectiveness of a Local Primary Care Incentive Scheme: A Difference-in-Differences Study.

Area of Science:

• Health Services Research
• Public Health
• Primary Care Medicine

Background:

• National financial incentive schemes for primary care quality improvement face criticism in the UK.
• There is a growing need for localized alternatives to national schemes.

Purpose of the Study:

• To investigate the association between a local incentive-based quality improvement scheme and all-cause emergency hospital admissions.
• To assess the impact of the scheme on socioeconomic inequalities in emergency admissions.

Main Methods:

• Difference-in-differences analysis was employed.
• Compared changes in emergency admission rates in an intervention city with a matched comparison population.
• The intervention was a local general practice incentive-based quality improvement scheme launched in 2011.

Main Results:

• Emergency admission rates decreased by 19 per 1,000 people in the intervention city relative to the comparison population (95% CI [17, 21]).
• The reduction in admissions was more pronounced in more disadvantaged populations.
• The scheme contributed to narrowing socioeconomic inequalities in emergency admissions.

Conclusions:

• Local incentive-based quality improvement schemes can be effective in reducing unplanned hospital admissions.
• Such localized approaches may help mitigate socioeconomic disparities in healthcare.
• Findings support the potential for similar strategies in other regions to improve primary care outcomes.
