Nearly all thirty most frequently used emergency department drugs experienced shortages from 2006-2019

The empty code cart: Drug shortages over time

PURPOSE

In high-acuity situations such as cardiac arrest, clinicians rely on prepared medications stocked in code carts to provide timely and accurate pharmacotherapy. We examined shortage trends for medications commonly used in code carts.

METHODS

Drug shortage data from 2001 to 2022 were retrieved from the University of Utah Drug Information Service (UUDIS) to characterize shortages reported for commonly used code cart medications. Data extracted included the number of shortages, shortage duration, drug characteristics, and reason for the shortage.

RESULTS

From 2001 to 2022, 71 drug shortages for code cart medications were reported. The number of new shortages peaked in 2010, and the number of total shortages peaked in 2010. At the end of the study period, 61 (84.7%) shortages had been resolved. For resolved shortages, the mean shortage duration was 18.2 months. The drug with the greatest number of reported shortages was dextrose (10 total), the drug with the longest resolved shortage was calcium chloride injection (116 months), and the drug with the longest active shortage was atropine injection (165 months at the end of the study period). Throughout the entire study period, only 2 suppliers provided commercially available prefilled syringes of dextrose for stocking on code carts. The most common reason for shortages, when reported, was manufacturing delays.

CONCLUSION

Medications commonly used in code carts were frequently impacted by drug shortages, which have the potential to impact patient care. Institutional protocols for mitigation and larger efforts to promote a more resilient drug supply chain are critical to ensure patient safety and quality care.

Drug supply and assurance: a cross-sectional study of drug shortage monitoring varieties in China

BACKGROUND

Drug shortage is a worldwide problem that seriously threatens public health. China released the most comprehensive list of key drug shortage monitoring varieties ever in 2022. We aim to analyze the attributes and characteristics of the medicines within the list to provide a reference for improving China's supply security of shortage drugs.

METHODS

We used public data to extract information on drug types, dosage forms, indications, classification of clinical uses, whether they were included in medical catalogs such as the National Essential Drugs, and the number of drug and active pharmaceutical ingredient (API) manufacturers. A descriptive statistical analysis was used.

RESULTS

Of the 980 drugs on the list, 99.59% were chemicals and 92.65% were injectables. Drugs for blood and hematopoietic organs, the cardiovascular system, and the digestive tract and metabolism ranked among the top three shortages. Verification of the medical catalogs showed that 90.41% of the drugs belonged to the national essential drugs, 95.10% were medicare drugs, 2.55% were volume-based procurement drugs, and 14.70% were for rare diseases, and 42.04% were for children. In terms of drug supply capacity, 21.33% of drug approvals are less than 10, and there were even 26 drugs for exclusive production, close to 90% of manufacturers need to purchase APIs from outside. Among the 256 APIs included in the list, 152 APIs had less than 10 manufacturers, and there were even 5 APIs produced by only one enterprise nationwide.

CONCLUSIONS

The situation of drug shortages in China was severe and complex, with serious shortages of medicines adapted to basic medical and healthcare needs and clinically necessary medicines, and a need to improve the production capacity of drugs and the ability to supply APIs. We recommend strengthening drug monitoring and stockpiling and accelerating the approval of shortage drugs to improve drug supply security.

Drug shortages in China: a cross-sectional study

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 < 0.05). Of the Emergency Drugs List, 72.0% (36/50) also experienced shortages, significantly higher than all the above categories (P < 0.05).

CONCLUSIONS

In China, drug shortages were severe and complicated. Drug shortages vary among economic regions but are not significant. In comparison, the national procurement pattern of volume-based drug purchasing may be conducive to alleviating the drug shortage problem. Collaboration of all partners was recommended to ensure the supply of clinically necessary drugs.

The Effect of an Iodinated Contrast Material Shortage on Ordering Patterns in the Emergency Department

Introduction Iodinated contrast media (ICM) is essential to emergency department care in differentiating and delineating life-threatening pathologies. In May 2022, due to the COVID-19 outbreak, there was an unprecedented disruption in the manufacturing of iodinated contrast. The primary goal of this study was to describe the effects of an ICM shortage on the ordering patterns of emergency medicine physicians. Methods This was a retrospective, observational study with a pre-/post-test design. The study included two 28-day periods. All subjects who underwent a CT were included in the study. The subgroup of patients who underwent a repeat CT with ICM contrast within 1-24 hours was identified. Results During the pre- and post-implementation study periods, 4,574 and 3,973 CT studies were performed. The median length of stay (p=0.013) and time to first CT (p<0.001) both decreased during the post-implementation period. During the post-implementation period, more non-contrast CTs were ordered (p<0.001). During the post-implementation period, there was an increase in non-contrast studies followed by a repeat study with contrast (p=0.003). Conclusions A global ICM shortage resulted in a shift in the ordering patterns of Emergency Medicine (EM) physicians. More non-contrast CT scans were ordered. However, there was also an increase in repeat imaging with ICM material.
