BackgroundDespite the advantages of the electronic registry which has been explained in other areas of health and other parts of the world, there has been no empirical research conducted with the aim of assessing the impact of the electronic immunization registry practices on the availability of immunization commodities.ObjectivesTo assess the effect of electronic immunization registry practices on the availability of immunization commodities.MethodsA cross-sectional study was carried out to health facilities providing vaccination services in Tanga City Council. A total of 27 health care workers in 27 health facilities were interviewed for availability of vaccines and their experience in using electronic immunization system in supply chain system functioning using structured questionnaires. The data from the vaccines manual ledger and electronic TImR system were also collected administered in April-June, 2019 specifically for Bacillus-Calmette Guerin (BCG), Diphtheria-Pertussis-Tetanus-Hepatis B-Haemophilus influenza type b (DPT-HepB-Hib), bi-oral polio vaccine (bOPV), Measles-Rubella and Human Papilloma Virus Vaccine (HPV). These data were analyzed by statistical software SPSS using one sample T test and 95% confidence interval.ResultsThe study affirmed that the mean numbers of children registered at the health facilities using electronic immunization registry was 1.5-3 times higher than the target population for the three months preceding the study given by the National Bureau of Statistics (NBS). The number of doses for the studied vaccines (DPT-HepB-Hib, measles rubella, HPV, BCG and bOPV) were found to be different in the manual and electronic TImR systems. Also, the number of doses available at the health facilities increased significantly with the number of the electronic system registered children.ConclusionThis study found that the adoption of Electronic immunization registry has improved the health supply chain in terms of improving the vaccines availability.

The effect of solar direct derive (SDD) from cold chain equipment on the quality and equity of health facilities’ immunization services is assessed using descriptive and explanatory research design by collecting data using a structured questionnaire from health workers in health centres and health posts of 56 purposely selected health facilities in Ethiopia. Quantitative data were collected from the EPI registry for the year 2014 as a baseline, and a follow-up review was made for the year 2018 performances. It was found that the new cold chain equipment, SDD refrigerators have a positive and significant effect on improving equity (Penta 3 coverage) and quality (Penta 3 -Measles dropout rate) of the immunization service. This helps to reduce the number of zero dose children.

BACKGROUND: A cold chain is a temperature-controlled supply chain with uninterrupted chain of activities that maintain a given temperature range that keep and maintain the quality of vaccines. Vaccines move through complex procedures and processes that require special attention and care. Effective cold chain systems require efficient end-to-end vaccine storage, handling, and stock management to maintain vaccines under strict temperature control of between 2 °C and 8 °C (for almost all vaccines). METHODS: A descriptive cross-sectional study design and mixed (qualitative and quantitative) research approach is employed to conducting the research. Data were collected through face to face in-depth interviews and questionnaires from Vaccinators and key persons from IPs. Prior to data collection, ethical approval was obtained from national Ministry of Health, Directorate of planning and M&E, and the University of Rwanda, Research Committee Board. Accordingly, data were collected after seeking the personal consent sought from the participants. RESULTS: The key findings from this study showed that the cold chain coverage has been improved compared to the result obtained in EPI coverage survey conducted in 2017. The results revealed that inadequate availability of EPI cold technicians, lack of fridge spare parts, trained staff, and adequate vaccine forecasting was the major challenges at county and the health facility level. CONCLUSIONS: The main factor that contributed positively in strengthening vaccines supply chain system in the Upper Nile State was the substantive increase in cold chain coverage. However, the role of the CCEOP in improving immunization coverage is still doubted due to lack of regular preventive maintenance, spare parts, and EPI technicians. The major challenges that affect the vaccines relevance, effectiveness, efficiency and sustainability were found to be mainly poor vaccines handling, due to inadequate knowledge on cold chain management.
