To evaluate the cold chain in the vaccination points of a health department in the autonomous region of Valencia, including training of the staff responsible for the cold chain.
We performed a crosssectional study to review all the vaccination points (n = 50, with 68 refrigerators) of a health department in the autonomous region of Valencia. A structured questionnaire was used to gather information on the characteristics of the vaccination center, the staff responsible for the cold chain, the infrastructure and control of the elements composing the cold chain, the procedures used in vaccine conservation and handling, and knowledge of the staff.
The response rate was 100%. Most of the refrigerators were domestic refrigerators without alarm systems to alert staff to technical failure or electrical cuts (76.7%), open door alarm (98.5%), external thermometer (92.6%), automatic defrosting facilities (76.5%), internal temperature sensors or connection to emergency circuits (85.3%). Temperatures were mostly in the correct range (83.9%) and the vaccines were correctly located (88.2%). At least one staff member was responsible for the vaccines in all centers. Food was found in 33.8% of the refrigerators, vaccines were conserved on the vaccination table on the day of vaccination in 32.4%, and the temperature chart was not recorded daily in 75%.
The appropriate temperature was maintained in five out of every six refrigerators. However, the vaccine infrastructure in primary care centers, as well as training of the staff responsible for the cold chain, should be improved.
评估巴伦西亚自治区某卫生部门疫苗接种点的冷链情况，包括对负责冷链的工作人员的培训。
我们开展了一项横断面研究，以审查巴伦西亚自治区某卫生部门的所有疫苗接种点（n = 50，配有68台冰箱）。使用结构化问卷收集有关疫苗接种中心的特征、负责冷链的工作人员、构成冷链的要素的基础设施和控制、疫苗保存和处理所采用的程序以及工作人员知识等方面的信息。
应答率为100%。大多数冰箱是没有警报系统来提醒工作人员技术故障或停电的家用冰箱（76.7%），有开门警报（98.5%）、外置温度计（92.6%）、自动除霜设施（76.5%）、内部温度传感器或与应急电路连接（85.3%）。温度大多在正确范围内（83.9%），疫苗存放正确（88.2%）。所有中心至少有一名工作人员负责疫苗。33.8%的冰箱里发现有食物，32.4%在接种当天疫苗保存在接种台上，75%没有每日记录温度图表。
每六台冰箱中有五台保持了适宜温度。然而，基层医疗中心的疫苗基础设施以及负责冷链的工作人员的培训仍需改进。
