Assessment of cold chain equipments and their management in government health facilities in a District of Delhi: A cross-sectional descriptive study

摘要

Background: Cold chain equipments (CCEs) at health facilities (HFs) are an essential part of the immunization supply chain (ISC). The CCEs in government HFs of Delhi were never assessed using the World Health Organization-United Nations Children's Fund (WHO-UNICEF) Effective Vaccine Management (EVM) tool except that of state vaccine store during National EVM assessment 2013. Objectives: The objective of the study was to assess the CCEs and their management in government HFs using the WHO-UNICEF EVM tool in a district of Delhi. Methods: The assessment was done during December 2017-March 2018 in one randomly selected district of Delhi. Sample size and site selection were done using the WHO EVM site selection tool. A total of 29 HFs were assessed along with District Vaccine Store. Questions on CCEs in EVM tool 1.0.9 were used for data collection. Results: Out of 56 electrical CCEs, 8.9% were nonfunctional, 48.2% were noncompliant with WHO standards, 5.4% were not chlorofluorocarbon free, 4.7% did not have temperature monitoring device, and 18.8% did not have stabilizer. Eighty-six percent of passive containers were compliant with the WHO standards. The storage capacity of electrical vaccine storage equipment was insufficient in 3.4%, passive container capacity in 65.5%, and ice packs preparation and storage capacity in 24.1% of HFs. There was no planned preventive maintenance of CCEs and no standard operating procedures for emergency event management. Conclusion: There was a shortage of vaccine storage, ice packs preparation and storage, and passive container capacity. Many CCEs used in ISC of assessed sites were noncompliant to the WHO standards. There was no PPM of CCEs and no guidelines for emergency event management.
