碩士 === 高雄醫學院 === 公共衛生學研究所 === 86 === AbstractVaccines will be harmful because of improper storage and handling.Since there are 12 % to 19% of 260000 to 270000 newborns in Taiwanprovince are vaccinated in the hospitals and clinics which arecontracted by the government health bureaus, it is very importantto understand whether the vaccines cold chain in this level are wellhandled.In this study, we sample some 200 from 600 hospitals and clinics inone-third ratio systematically, which are contracted to providevaccination services with the health bureaus or health centers. Wesurvey their refrigerators with the cold chain monitors (3M''s product)from Jan. 1998 to May. 1998. Since the health centers'' cold chainsystems had been proved effectiveness, we sample 100 from 299 healthcenters in the same way for comparison.The questionnaires are made for the persons of the hospitals and clinicswho are in charged of the vaccine management. There are two parts in thisquestionnaire, one is completed by the vaccine managers of the hospitalsand clinics. This part contains the basic information of the hospitalsand clinics in operating vaccination services, their equipment for vaccinestorage, the way they handle the vaccines, the managers'' knowledge onhandling vaccines and how they get the information about handling the cold chain. The other part is completed by the workers of the health bureaus andthe health centers in charged of vaccine management. It contains how thehospitals manage the vaccines, whether the refrigerators contain food ordrugs, the record of the refrigerator temperature, the vaccine positionsin the refrigerators. The visitors also had to check the hospitals andclinics vaccine managers on how they read the refrigerators'' temperature,cold chain monitors, freeze watches, and how they do the shake test of thevaccine. 41 hospitals'' questionnaires and 135 clinics'' were collected andanalyzed, the results show: 1. Most the hospitals and clinics'' OPD time isvery frequent that can offer the parents in taking their babies to getvaccination. 2. The vaccines'' transportation from the health bureaus orhealth centers to the hospitals and clinics is safe since all thetransportation''s finished in less than 30 minutes and the vaccines are allstored in closed containers with ice bags. 3. The hospitals and the clinics''vaccines at orage equipment are not good enough because 34% hospitals and 48%clinics use one- door refrigerators in which the temperature control is thoughtto be much unstable. At the meantime there are also 95% hospitals and 48%clinics don''t have any electric power suppliers to supply power when theoutside one is broke. And this will increase the potential dangers ofvaccine storage. 4. Part of the hospitals and clinics vaccine mangers''knowledge does not enough, and this may harm the vaccines'' potency inmistaking handling it.There are 42 hospitals, 142 clinics and 95 health centers finished in therefrigerator monitoring using the cold chain monitors. The result shows36.4% hospitals'' cold chain monitors and clinics'' changed colors at Adegree, 4.5% at B degree, and there is only one clinic at C degree. Thereare 24.2% health centers (the control group) changed color in A degree, andno one changed in B and C degree. The odds ratio for hospitals and clinicsare 2.348 (1.086 - 5.074) and 1.979 (1.110 - 3.528) respectively usingthe health centers as the reference. Because there are only few hospitalsand clinics'' cold chain monitors changed color in B and C degree and thepotency of vaccines is qualified in a reasonable short times changed colorin A degree. We consider the vaccines used in the hospitals and clinics aresafe If the health bureaus can control the interval of the pick-up andquality of vaccines without any of the following situations such as thelong period shortcut of electric power, severe mechanic problems numbersand ergonomic errors, the potency of vaccines will not be reduced too muchas to affect the normal function of the vaccines.
