Costs and Cost Drivers of Providing Option B+ Services to Mother-Baby Pairs for PMTCT of HIV in Health Centre IV Facilities in Jinja District, Uganda.

The average total cost of Option B+ services per HC was 66,512.7 (range: 32,168.2-102,831.1) USD over the 2-year period. The average unit cost of Option B+ services per mother-baby pair was USD 441.9 (range: 422.5-502.6). ART for mothers was the biggest driver of total mean costs (percent contribution: 62.6%; range: 56.0%-65.5%) followed by facility personnel (percent contribution: 8.2%; range: 7.7%-11.6%), and facility-level monitoring and quality improvement (percent contribution: 6.0%; range: 3.2%-12.3%). Conclusions and Recommendations. ART for mothers was the major cost driver. Efforts to lower the cost of ART for PMTCT would make delivery of Option B+ affordable and sustainable.
