Using sales data from 22 Canadian pharmacies and historical drug shortage data, we built machine learning models predicting shortages for the majority of the drugs in the most-dispensed interchangeable groups in Canada. The models consider many variables, including the average days of a drug supply per patient, the total days of a drug supply, previous shortages, and the hierarchy of drugs within different drug groups and therapeutic classes. Once in production, the models will allow pharmacists to optimize their orders and inventories, and ultimately reduce the impact of drug shortages on their patients and operations. Drug shortages are a complex, global problem [ 1 , 2 ] with negative impacts on patients, pharmacists, and the entire health care system.

FDA News. There are two main data limitations, both related to historical shortage data. The models consider many variables, including the average days of a drug supply per patient, the total days of a drug supply, previous shortages, and the hierarchy of drugs within different drug groups and therapeutic classes. Multiple pharmacists making the same interpretation could, hypothetically, place several orders and increase demand enough to create a drug shortage that would not have occurred otherwise. Int J Forecasting. Figure 1 illustrates how this reported data fits into the hierarchy of drugs and therapeutics. Springer, pp — Information on baseline serum potassium and creatinine concentrations, concurrent medications, demographic information, and ejection fractions was obtained. Impact of drug shortages on US health systems. We will refer to the outcome in the holdout set as forecasts in the rest of this paper. Drug Shortages Canada Drug shortages Canada database. Figure 5 shows an example of a validation configuration for a set of five resamples. The dots represent the monthly quantities for each measure, while the solid line represents the three-month exponential moving average.

The pills are not being discontinued according to the company. The first of these factors was not in the data, thus we assumed that all different pack sizes of a given DIN are equally important to the pharmacies e. We had access to anonymized data covering 22 pharmacies across Ontario. To avoid such a scenario, converting the score to a qualitative scale as we did before is desirable e. Table 3 Importance of the variables seen in the models, separated by lagged month, and averaged across all IGs. Figure 5 shows an example of a validation configuration for a set of five resamples. Another feature that may be indicative of drug shortage is the month-to-month variation in the ratio of DINs being dispensed within an IG over time. Such sourcing of alternative medication can occur multiple times a day [ 13 ] and the labor cost incurred can be significant median of 3 hours per week per pharmacist [ 14 ]. They also have access to historical shortage data from public databases such as Drug Shortages Canada [ 17 ] or its FDA equivalent [ 19 ]. References 1.
