  1. P steps relate to procedural aspects, S steps relate to test safety and A steps relate to test accuracy. Of the 103 participating CHWs, baseline checklists for 13 CHWs were unable to be located and were not included in baseline data analysis; 90 baseline observations exist, although some checklists (n = 14) had incomplete observation data resulting missing scores for no more than two steps.
