Evaluation of cold chain system in rural areas of Haryana.
Evaluation of cold chain system was done in a time bound study during August and September months of 1992 in two districts of Haryana as there were frequent breakdowns of icelined refrigerators during the previous year. The study revealed that defective stabilizers and electricity plugs and sockets were the reason of breakdown in many cases. Temperature maintenance and functioning of deep freezers was satisfactory. Retrospective analysis showed that the polio vaccine samples picked up during 1990-92 were found to be satisfactory by CRI, Kasauli. Use of two ice-pick carrier and thermos flasks was associated with poor temperature maintenance. Seven vaccine carriers out of 25 examined had cracked wall lining. Lids of carriers were also not kept tight during vaccination sessions. Response lag of the health workers and medical officers in case of breakdowns was delayed. A one day refresher course exclusively on cold chain maintenance at community health centre level is recommended.
