Early warning indicators
Monitoring the extent to which ART sites function to minimize preventable HIV drug resistance (HIVDR) is the highest priority. The HIVDR early warning indicators (EWI) are ART site-based indicators associated with HIVDR prevention. Data are abstracted from medical and pharmacy records for a limited time period each year; ARV prescribing practices, on-time ART drug pick-up and clinic appointment-keeping, percentages of patients lost to follow-up and still on first-line ART at 12 months, and ARV drug stock-outs and shortages, are monitored. Data collection may be integrated with other monitoring of ART or assessing ART data quality.
