6Assessment activity C: Quality assurance assessment of PMTCT HIV testing at ANC HSS sites

This section describes methods for the conduct of a QA assessment of PMTCT HIV testing at ANC HSS sites (Figure 10). This activity addresses assessment area 5 (the state of QA practices for PMTCT HIV testing at ANC HSS sites).

Assessment Activity C.

In order for PMTCT data to serve as the basis for HSS, it is important to maintain a robust QA system to support routine PMTCT HIV testing, including training, supervision, adequate supplies and storage, appropriate record-keeping, infrastructure, available standards and guides, and external quality assurance.(42,43,44)

6.1. Data collection for a QA assessment of PMTCT HIV testing

A sample QA checklist for PMTCT HIV testing has been developed to assess QA of all areas of PMTCT HIV testing (Appendix E). The checklist records the presence of QA elements in PMTCT HIV testing in three phase categories: pre-testing phase, testing phase and post-testing phase.

It is suggested that the QA checklist for PMTCT HIV testing be completed by an assessment study staff member (not a site staff member) with laboratory training. The study staff member completes the checklist by examining site PMTCT HIV testing procedures and interviewing site staff involved in conducting HIV rapid testing. Optimally, the checklist would be completed outside of the ANC HSS period to avoid any bias associated with improved resources, training and supervision provided during the ANC HSS period. The sample QA checklist for PMTCT HIV testing may be adapted to the local country context and piloted before implementation.

6.2. Analysis of data derived from a QA assessment of PMTCT HIV testing

The sample QA checklist for PMTCT HIV testing contains a built-in analysis function. Every QA element that meets the defined standard is worth one point. Within each of the checklist's three phase categories (pre-testing phase, testing phase and post-testing phase), the points are added and divided by the total number of possible points in that phase category to produce a phase category assessment score. As a general standard, if the assessment score is at least 80% in each of the three phase categories, site PMTCT HIV testing may be considered to be within acceptable QA parameters.
