Abstract Background Drug shortages significantly threaten public health and medical service provision worldwide. Research evidence on the complete picture of drug shortages is currently scant in China. This study aimed to provide a descriptive overview and a reference for alleviating of drug shortages in China. Methods National and provincial lists of drug shortages issued in China from 2018 to 2021 were collected and summarized. The information on essential medicines, medical insurance drugs, emergency drugs, and volume-based purchasing drugs was then matched with a drug shortage list to analyse the characteristics, proportion and incidence of drug shortage on each list based on the analysis of information such as dosage form, shortage frequency, and Anatomical Therapeutic Chemical (ATC) classification of the drugs in shortage. Results A total of 24 provinces issued drug shortages lists involving 408 drugs from 2018 to 2021. All 58 drugs in the national drug list were included on the provincial drug shortage list. Among all the drugs in shortage, the most significant shortage involved injections, accounting for 45.3% (185/408). Ninety-five drugs (23.3%) were in shortage 5 times (annual shortage > 1 time) or more in the provincial lists, and 199 drugs (48.8%) were on the shortage list only once. In terms of therapeutic property, nearly all categories of drugs had been reported in shortage, among which cardiovascular drugs, nervous system drugs, anti-tumor and immunomodulatory drugs, and blood and hematopoietic organ drugs accounted for more than 10%. There is no significant difference in drug shortage among economic regions. Comparing drugs in shortage and various lists, 81.9% (334/408), 51.0% (208/408) and 67.9% (277/408) fell on the National Medical Insurance Drug List, National Essential Medicines List, and WHO Model List of Essential Medicines, respectively, while the volume-based purchasing drugs accounted for 3.4% (14 drugs). The incidence of drug shortages on NEML, WHO Model List of Essential Medicines and medical insurance category A was significantly higher than that of medical insurance category B and volume-based purchasing drugs (P |
