AbstractOBJECTIVES
To examine the effect of individual and area-level characteristics on the probability of public-private mix (PPM) support (PPM coverage) for tuberculosis (TB).METHODSThis study is a retrospective cohort design using TB reporting and treatment management data in Korea. We analyzed PPM coverage through multilevel logistic regression and empirical Bayesian estimation according to individual and area-level characteristics and their interaction.RESULTSPatients aged 0-29 years, women, of Korean nationality, treated at a general hospital, a one-time reporting, urban areas, and the lowest deprivation index (DI) showed higher PPM coverage. Due to the cross-level interaction, PPM coverage in the urban areas (slope=-0.048, p<0.001) had a higher level but a steeper negative deprivation gradient than in rural areas (slope= -0.015, p<0.001). For a general hospital, the PPM coverage in urban is high but more significantly decreased than in rural areas with the higher DI (urban: slope=-0.047, p<0.001; rural: slope=-0.031, p<0.001). For clinics and hospitals, the effect of DI did not appear in urban areas, but in rural areas, the higher the DI, the higher the PPM coverage with a slope of 0.046 (p<0.001) and 0.063 (p<0.001), respectively.CONCLUSIONSThe PPM program created a significant disparity in PPM coverage between urban-rural areas and type of healthcare provider according to DI. Considering the high risk of TB incidence in areas with higher DI, institutional improvement and program redesign are needed to improve accessibility and equity. -
SummaryKorean summary
다수준 분석을 통해 시행하여 PPM(Public-Private Mix) 사업의 주요한 평가 지표인 PPM coverage를 접근성과 형평성 관점에서 검토하였다. PPM 사업은 전반적으로 치료지원 수준을 높이는 효과가 있었지만, 도시화수준, 박탈 수준과 치료지원기관 선택의 3원 교차수준 교호작용의 결과로 지역간 PPM coverage에 지역박탈지수에 따른 큰 기울기를 가진 격차를 만들었다. 지역박탈수준이 큰 지역의 높은 결핵 발생 위험을 고려하면 효율성과 함께 형평성 수준을 향상시킬 수 있는 제도적 개선과 프로그램의 보완이 필요하다.Key Message
This study analyzed the effect of individual and area-level characteristics on the probability of public-private mix (PPM) coverage for tuberculosis (TB) in Korea. The PPM program created a significant disparity in PPM coverage between urban-rural areas and type of healthcare provider according to deprivation index (DI). Given the high TB risk in areas with high DI, there is a need for institutional improvement and program redesign to improve accessibility and equity.
