A structured abstraction tool was used to extract secondary data to measure primary and secondary outcome data at baseline and endline. The primary data included the total number of children under-one-year (target population) obtained through the house-to-house registration. A CHW register was developed and used to collect primary data on the target population (denominator) at baseline and was used to update the respective health facility target population in both the control and intervention arms. Health facilities adopted the house-to-house registration population data instead of the estimated projections from the district office because it was believed to be a more accurate representation. The key components of the CHW register included: location; age; vaccination status of the child; and telephone contacts of the caregiver(s).The secondary data included the number of children that received BCG, DPT3, MR, PCV3, OPV3 and Rota2 antigens/vaccines. Data was abstracted from child immunization registers and tally sheets three months before and three months after the intervention in 5 health facilities. At both time points (baseline and endline), secondary data was abstracted from health facility records (child immunization registers, tally sheets and health facility based monthly reports and the district health management information system (DHIS). The denominator (target population) used in measurement of coverage in both arms at baseline and endline considered the data from the house-to-house registration and not the projected district population estimates.The child immunization register is a paper-based ministry of health data collection tool found in all health facilities offering vaccination services and captures the following information; health facility name; child’s name; mother’s name; father’s name; contact information for mother/father; address of the child; sex; date of birth; age; weight of child; dates when particular vaccines, deworming and vitamin A supplementation are administered; and status of infant screening for Human immunodeficiency virus (HIV). First time registration of children occurs as and when they attend vaccination services at the health facility.The Ugandan vaccination schedule for children under-one-year as of the year 2020 included the following vaccines: Oral Polio vaccine (OPV); Bacille Calmette-Guérin (BCG); Diphtheria, Pertussis, Tetanus, Hepatitis B and Haemophilus Influenza vaccine (DPT-HepB-Hib); Pneumococcal conjugate vaccine (PCV); Rotavirus vaccine; Inactivated polio vaccine (IPV); and Measles-Rubella vaccine (MR). Vaccination services are offered for free in all the Ugandan government health facilities.
