Perception of health workers on the use of 30-day temperature recorders

The ability to monitor vaccines for optimal temperatures throughout the supply chain is a cornerstone of successful immunization programmes. As stated in the WHO Vaccine Management Handbook, in \"How to monitor temperatures in the vaccine supply chain\", it is considered best practice to use 30 day temperature recorders (30 DTRs) as temperature monitoring devices for vaccine refrigerators. 30 DTR devices not only provide spot temperature readings at the time of inspection, they can also store the excursions and provide evidence of what occurred between the manual readings. This evidence brief provides supply chain managers in low and middle-income countries with a summary of how health workers throughout Africa perceive the use of 30 DTR devices.
