Pay-for-performance programmes reduce stroke risks in patients with type 2 diabetes: a national cohort study

Area of Science:

• Health Services Research
• Cardiovascular Epidemiology
• Diabetes Management

Background:

• Pay-for-performance (P4P) programs incentivize healthcare providers to improve care quality.
• Taiwan's P4P program for diabetes voluntarily enrolls patients with type 2 diabetes.
• Stroke is a significant complication for individuals with type 2 diabetes mellitus (DM).

Purpose of the Study:

• To compare the risk of stroke in type 2 diabetes patients enrolled in a P4P program versus those not enrolled.
• To identify factors associated with stroke risk within the P4P program framework.

Main Methods:

• Retrospective cohort study (2002-2013) in Taiwan involving 459,726 patients with type 2 DM.
• Propensity score matching was used to create comparable P4P and non-P4P groups.
• Cox proportional hazards models analyzed stroke risk, stratifying by sex.

Main Results:

• P4P participants had a significantly lower overall stroke risk (HR=0.97).
• A significantly reduced risk of hemorrhagic stroke was observed in P4P participants (HR=0.87).
• No significant difference in ischemic stroke risk was found; reduced risk was noted in males but not females.

Conclusions:

• Taiwan's Diabetes P4P program is associated with a significant reduction in stroke risk, especially hemorrhagic stroke.
• The findings support the continued promotion of this P4P program for type 2 diabetes management.
• Further research may explore sex-specific benefits and mechanisms of risk reduction.
