Pay-for-performance in Taiwan: A systematic review and meta-analysis of the empirical literature

Objectives

This study aimed to assess the impact of pay-for-performance (P4P) programmes on healthcare in Taiwan.

Study design

This was a systematic review and meta-analysis.

Methods

A systematic literature search was performed using the PubMed, Medline, Embase, Cochrane review, Scopus, Web of Science and PsycINFO databases up to July 2023. Meta-analysis of the available outcomes was conducted using a random-effects model.

Results

The search yielded 85 studies, of which 58 investigated the programme for diabetes mellitus (DM), eight looked at the programme for chronic kidney disease (CKD), and the remaining studies examined programmes for breast cancer, tuberculosis, schizophrenia and chronic obstructive pulmonary disease. The DM P4P programme was a cost-effective strategy associated with reduced hospitalisation and subsequent complications. The CKD P4P was associated with a lower risk of dialysis initiation. The P4P programme also improved outcomes in breast cancer, cure rates in tuberculosis, reduced admissions for schizophrenia and reduced acute exacerbation in chronic obstructive pulmonary disease. The meta-analysis revealed that the P4P programme for DM (odds ratio [OR] = 0.59; 95% confidence interval [CI] = 0.48–0.73) and CKD (OR = 0.73; 95% CI = 0.67–0.81) significantly reduced mortality risk. However, participation rate in the DM P4P programme was only 19% in 2014.

Conclusions

P4P programmes in Taiwan improve quality of care. However, participation was voluntary and the participation rate was very low, raising the concern of selective enrolment of participants (i.e. ‘cherry-picking’ behaviour) by physicians. Future programme reforms should focus on well-designed features with the aim of reducing healthcare disparities.
