Background:
Viral load (VL) scale-up efforts have largely focused on laboratory systems, with less attention on facility-level strengthening of staff who facilitate VL testing. To address this gap we implemented a quality improvement (QI) program at 13 health facilities in central and southern Malawi.
Methods:
QI program tools focused on patient and provider VL knowledge and clarification of site-level roles and responsibilities, including the designation of a VL 'focal person' to oversee all VL activities. T-tests were used to compare differences in VL testing before (November 2016-April 2017) and after (May 2017-November 2017) the intervention.
Results:
The mean number of VL tests performed significantly increased after implementation of the QI program. Overall there was a 164% increase in the mean number of routine VL tests performed per month (p<0.001). Increased VL testing was sustained during the 6 months of follow-up.
Conclusions:
A simple QI program focused on improving VL knowledge among patients and providers, and clarifying staff roles at a facility level increased VL testing over a 6-month period. Further investigation is needed on whether this program can be scaled in different settings across sub-Saharan Africa and on the duration of follow-up required for sustained improvements in VL testing.

Quality Control
Quality control helps track data, visualize trends, and identify variations, making it easier to detect deviations that may affect the accuracy of an analysis. One way to do this is by generating a quality control chart, which...
