To analyze the alarm information of monitoring platform for vaccine cold chain in Shandong Province and to provide scientific basis for improving the cold chain guarantee level of vaccines.
We have collected data on overtemperature and blackout alarms from January 1 to December 31, 2024 in Shandong Province through the cold chain monitoring platform, and descriptive analysis was conducted by season, region, and unit type.
The cold chain monitoring platform in Shandong Province is equipped with 5 463 data recording devices and 25 159 data collection devices, which monitor in real-time the temperature of vaccine storage and transportation in 16 cities’ Centers for Disease Control and Prevention and vaccination units throughout the province. The summer month of July has the highest number of alarm information, with an average of 4.2 for overtemperature and 2.0 for blackout alarm. The winter month of December has the lowest number of alarm information, with an average of 1.1 for both overtemperature and blackout alarms. The average number of overtemperature alarms in Tai’an City, Rizhao City, and Heze City exceeds 40, while the average number of overtemperature alarms in Jining City is at least 17.6. The average number of blackout alarms in Binzhou City, Liaocheng City, Heze City, and Dezhou City exceeds 20, while Jinan City has the lowest number of blackout alarms, with an average of 10.1. The CDC has the highest number of overtemperature alarms, with an average of 59.7 alarms. The routine vaccination clinic has the highest number of blackout alarms, with an average of 19.8 alarms. The average number of overtemperature alarms and blackout alarms in the rabies exposure prevention and treatment outpatient department are relatively high, with 48.2 and 18.8 alarms, respectively.
There are seasonal, regional, and unit type differences in vaccine cold chain alarms, and targeted measures should be taken to strengthen vaccine cold chain management and ensure vaccine safety.
