Effects of different storage and transportation devices on the temperatures of"internet plus drug delivery"in hospital under high-temperature conditions in summer
OBJECTIVE To explore suitable storage and transportation conditions for"internet plus drug delivery"under high-temperature conditions.METHODS A survey on high-temperature conditions in summer in Beijing was conducted;a retrospective analysis was conducted on"internet plus drug delivery"orders in our hospital from July 2021 to June 2022,summarizing the proportion and delivery range of drugs under different storage and transportation conditions.Additionally,simulation and validation experiments were performed to investigate optimal drug storage and transportation devices for"internet plus drug delivery"in Beijing under high-temperature conditions in summer.RESULTS The monthly average temperature in Beijing from June to August consistently exceeded 25.0℃between 1991 and 2022.From July 2021 to June 2022,a total of 104 drugs were required to be stored below 25.0℃,accounting for 31.23%of the 333 drugs listed in our hospital's"internet plus drug delivery"catalog in Beijing.These drugs were delivered 1 058 times,accounting for 19.63%of the total deliveries.Simulation and validation experiments demonstrated that the average maximum temperature during the next-day delivery process of"carton + foam box + composite aluminum film pearl cotton + 500 g ice bag×2 + gas column bag"was 9.6℃,the average minimum temperature was 2.7℃,and all the temperatures remained below 15.0℃,which could effectively ensure the quality of drugs.CONCLUSIONS Under the high-temperature conditions in summer in Beijing,the storage and transportation device of"carton + foam box + composite aluminum film pearl cotton + 500 g ice bag×2 + gas column bag"can meet the temperature requirements specified in the drug storage instructions for Beijing intra-city drug delivery.
