Performance characteristics of an HIV risk screening tool in Uganda

Introduction: Improving HIV testing efficiency has been documented to save financial and material resources for health.  In October 2019, the Ministry of HealthH Uganda deployed an HIV risk screening tool for use in 24 health facilities targeting clients aged 15 years and above in both outpatient and Voluntary Counselling and Testing departments.
Methods: We conducted a retrospective secondary data analysis of routinely collected HIV risk screening program data in Uganda, collected from October to November 2019, to determine the performance characteristics of the adolescent and adult HIV risk screening tool in public health facility settings. Statistical measures for the risk screening tool performance included sensitivity, specificity, positive and negative predictive values, and cost analysis. 
Results: A total of 19,854 clients were screened for HIV testing eligibility; we excluded 150 records with incomplete testing information. The overall positivity rate (cluster-weighted prevalen..., We conducted a secondary data analysis, of DHIS2 data from 24 health facilities in Uganda, on clients who were screened for HIV testing eligibility using a risk screening tool, and tested for HIV. All clients that were screened were tested irrespective of their screening outcome. The data had been collected and de-identified before being reported in the DHIS2. 
We received approval from Ministry of Health Uganda to access the DHIS2 data from district Biostatiscians, and we cleaned the dataset by removing entries with missing values, suing the excel sheet, Excel,
