Adherence to WHO vaccine storage codes and vaccine cold chain management practices at primary healthcare facilities in Dalocha District of Silt'e Zone, Ethiopia

Abstract

Background The main elements of effective vaccine cold chain management at the immunization service delivery point are well-trained vaccine cold chain handlers, vaccine storage equipment, and appropriate vaccine management procedures. Vaccine cold chain handlers must have enough expertise to provide the correct vaccine at the right time, maintain vaccine potency, and minimize vaccination failures. The study assessed knowledge of vaccine cold chain handlers on vaccine cold chain management, adherence to the WHO vaccine storage codes and vaccine cold chain management practice at primary health facilities in Dalocha district of Silt'e zone. Method Institutional-based cross-sectional study was done at twenty-eight primary health facilities. One hundred forty primary health workers were drawn from four health centers and twenty-four health posts operating in Dalocha woreda of Silt'e zone, SNNPR, Ethiopia. A self-administered questionnaires and on-spot observation checklists were adapted from the WHO and WHO-UNICEF-effective vaccine management assessment tools to collect data from cold chain unit of the primary healthcare facilities. Data were entered to EPI data version 3.1; exported and analyzed using SPSS version 22. Statistical analysis was carried out to determine the level of knowledge, adherence to WHO cold chain management guideline and vaccine handling practice. The relationship that the knowledge of primary healthcare workers, primary healthcare workers training status, primary healthcare facilities' adherence to WHO vaccine storage codes, and length of work experience of primary health care workers have with the vaccine management practice were also explored Result Above Half (54%) of the respondents have satisfactory knowledge of vaccine cold chain management. One hundred (71.4%) vaccine cold chain handlers did point correctly to the recommended range of temperature (2°C -8°C) for vaccine storage. Around two-thirds (63.6%) of them were aware of the twice-daily temperature recordings. Nearly half, (46.2%) of primary healthcare facilities have experienced poor adherence to the WHO storage practice codes. Around three-fifths of the observed primary healthcare facilities have registered undesirable vaccine management practices. The primary healthcare workers who received training on vaccine cold chain management (χ2 = 0.058, p=0.015), served at primary health care facilities for more five years (χ2 =18.545, p≤0.001), shown good adherence to WHO vaccine storage code (χ2 =18.545, p≤0.001), have sufficient knowledge on vaccine cold chain management (χ2=4.210, p≤0.031) were all significantly associated with desirable vaccine cold chain management practice. Conclusion There is a gap in vaccine cold chain handlers’ knowledge about vaccine cold chain management and less than desirable adherence to WHO vaccine storage codes at primary healthcare facilities in Dalocha district. The majority of the observed primary health facilities have registered poor vaccine management practices. Everyone who has a stake in the cold chain management of vaccines should do their share, individually and collectively, to guarantee that everyone reaps the benefits of an effective cold chain.

Vaccine Management Knowledge and Practice of Health workers in Yemen

“…In this study, 94.6% of the respondents demonstrated good knowledge of shake test for suspected frozen vaccines. This result is by far higher than those reported in similar studies in Ethiopia ranging from (36.2% to 53.3%) [7,16,22], India (40%) [26] and Nigeria (51.6%) [20] and Dalocha District of Silt'e Zone, Ethiopia (56.4%) [12].…”

“…Vaccine cold chain handlers are the most crucial personnel at a cold chain point as their correct knowledge and cold chain practices, vaccine management, and handling are immensely vital for the success of the Universal Immunization Programme [12]. In this study, 80% of the health workers had good knowledge of vaccine management and 43.7% knew that vaccine forecasting is the first step in vaccine management.…”

“…Emphasis has long been placed on keeping vaccines cold, with less attention devoted to the prevention of vaccine damage from freezing. Freezing of vaccines in the cold chain is commonplace, potentially resulting in the widespread delivery of vaccines whose potency has been compromised [12].…”

“…Jurnal Keperawatan Padjadjaran, Volume 10, Issue 3, December 2022 need additional training in vaccine governance to effectively manage immunisation activities, from injection techniques and reporting to vaccine storage (Feyisa et al, 2022;Nicol et al, 2019). Sustained policies to vaccinate children must continue in the changing healthcare environment.…”

Vaccine management practices among healthcare workers in Morogoro, Tanzania: a cross-sectional study

“…Healthcare systems worldwide rely on a competent supply chain system for the storage and transportation of health supplies at the right time, to the right place and in the proper condition equitably to all children for the welfare of all communities against vaccine-preventable diseases [17]. To ensure the effectiveness of vaccine supply, the health supply chains require effective management systems to handle vaccines and prevent wastage through providing healthcare workers with the necessary training and devices for vaccine management at all storage points [18][19][20].…”
