3.7. Sampling Procedures 
An electronic sampling frame of women aged from 25 to 49 years would be obtained via the Luweero district hospital HIV clinic. The women’s history of CC screening could be reviewed in their files. All women who had not been screened at all, not been screened within the last three years, had abnormal screening results, or had been screened more than 1 year ago with normal results, attending the HIV clinic, could be included in the sampling frame. The first participant would be randomly selected, and the subsequent women would be systematically selected using an interval of 2. Purposive sampling would be used to allocate women for IDIs, and expert opinions would be used to collect cost data from key informants and documents.
