Monitoring adherence to cold chain storage of vaccines in 2014 in the Malopolska province

BACKGROUND AND AIM OF THE STUDY: The principles of "cold chain" have been developed for the safe transport and storage of vaccines because of their sensitivity to temperature and are guidelines for use in all countries. Available information on adherence to the principles of the "cold chain" by healthcare providers in Poland is insufficient. The aim of the study was to assess compliance with these rules in storing vaccines by vaccination centers implementing an immunization program in 2014 in the Malopolska province MATERIAL AND METHODS: The study was conducted in 111 vaccination centers in 19 districts of Malopolska, which represents 12% of all vaccination centers in the Malopolska province in 2014. The selection of vaccination centers for the study was not random. During a routine inspection of vaccination centers, an employee of the District Sanitary-Epidemiological Station conducted a study using a specially-prepared questionnaire. Inspections in vaccination centers which qualified for the study were conducted from March to September 2015. RESULTS: Among the analyzed vaccinations centers 90% had a refrigerator or refrigerator-freezer, and 10% a pharmaceutical refrigerator. 3.6% of refrigerators were produced before 2000. A 24-hour recording of the temperature was conducted in 67.6% vaccination centers. 40.5% of vaccination centers had a 24-hour system of recording and notification when temperature parameters had been exceeded in refrigeration devices. 22.5% of vaccination centers had emergency power supply. 13.5% of vaccination centers a power failure occurred in refrigerators, including 40% of the vaccination centers which had a text message notification system.. Total cost of destroyed vaccines amounted to over 20 thousand zl. SUMMARY: Correct storage conditions are needed for vaccines to maintain their full effectiveness, which is why it is necessary to intensify efforts to ensure compliance with the principles of the cold chain in the storage of vaccines by healthcare providers.
