Federal government websites often end in. The site is secure. Drug shortages are a global and complex issue having negative impacts on patients, pharmacists, and the broader health care system. 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.

Spironolactone shortage

We evaluated how well patients taking spironolactone were monitored for hyperkalemia, as well as the association between spironolactone and hyperkalemia. Only two thirds of patients received testing for serum potassium and creatinine levels, and higher baseline serum creatinine levels predicted a high risk of hyperkalemia. These results indicate that appropriate patient selection and close monitoring are essential, especially for patients with renal impairment. Unfortunately, morbidity and mortality rates associated with hyperkalemia have risen to levels higher than those seen prior to RALES. Therefore, we studied criteria for the selection of patients for spironolactone therapy and how well patients taking spironolactone are monitored for hyperkalemia. We examined the outpatient and inpatient electronic files of CHF patients who were prescribed spironolactone between September 2, , and April 1, Information on baseline serum potassium and creatinine concentrations, concurrent medications, demographic information, and ejection fractions was obtained. We also reviewed follow-up laboratory tests for these patients. Peak serum creatinine and potassium levels within 3 months of initiating spironolactone treatment were identified. When follow-up laboratory tests within 3 months of starting spironolactone treatment were missing, the records were examined for an explanation.

Multiple pharmacists making the same spironolactone shortage could, hypothetically, place several orders and increase demand enough to create a drug shortage that would not have occurred otherwise. It includes coverage options and replacement products PharmaCare is covering during the shortage, spironolactone shortage.

September 19, There is currently a shortage of spironolactone Aldactone in Canada. I have spoken with representatives from Pfizer Canada and USA this morning again and the following are updates. There is a shortage of both 25 mg and mg supplies Canada due to a backorder. The pills are not being discontinued according to the company.

When spironolactone was originally developed, scientific studies were investigating epithelial ion transport; understanding ion transport was in its formative stages. The path to the eventual arrival of spironolactone on the US market was a complicated one, with its release finally occurring at a time when Donald Rumsfeld, the current Secretary of Defense, was chief executive officer of G. Spironolactone use in the s and s was fairly widespread for the treatment of hypertension, primary aldosteronism, and edematous conditions; i. What had we learned from the initial treatment experience with spironolactone? The onset of action for spironolactone was found to be characteristically slow, with a peak response at times of 48 hours or more after the first dose.

Modelling For modelling, we considered a total of IGs and corresponding DINs to include a breadth of drugs and drug shortages and sizes thereof. The importance of the variables can be separated by lagged month, as shown in Table 3. Hepatology Hepatology Hepatology. An increase in baseline serum creatinine level was directly related to an increase in the incidence of hyperkalemia. BNP, body build, and drug monitoring. By adding models on top of each other iteratively, the errors of previous models are corrected by the next model, until the training data is accurately predicted or reproduced by the model. Jeff Donovan, a Canadian and US board certified dermatologist specializing exclusively in hair loss. Third, we design this model to be implementable by pharmacies, which do have access to demand-side data and reported shortage data, but generally do not have access to supply-side data since they have limited visibility on the supply chain of drug manufacturers. The modeling process and related feature importance measurements offer pharmacists and other health care practitioners a deeper understanding of the factors associated with drug shortages. Open in a separate window. When follow-up laboratory tests within 3 months of starting spironolactone treatment were missing, the records were examined for an explanation. On the measure of concentration with special reference to income and statistics. Shortage data was downloaded from the Drug Shortages Canada [ 17 ] website. An illustration of this shortage impact score for one specific IG over time is shown in Fig. We are working at better predicting the demand for drugs at each pharmacy using machine learning [ 48 ].

.

It is recommended that pharmacists monitor drug supply closely so they can act swiftly in the event of a shortage [ 26 ]. For PharmaCare coverage of a specific drug, use the Formulary Search. By early November, the mg pills should again be available as well. Highlights Using sales data from 22 Canadian pharmacies and historical drug shortage data, we built supervised machine learning models able to predict shortages for the majority of the drugs that are in the most dispensed interchangeable groups in Canada. XGBoost is an advanced regression technique which has gained popularity due to its simplicity in implementation, its accuracy, speed, and scalability [ 41 ]. Mineralocorticoid receptor antagonists reduce cardiac remodeling and thereby aid cardiac function and decrease mortality. For patients, drug shortages can have major implications, for instance when drugs against severe allergies [ 5 ], severe pain [ 6 , 7 ], mental illnesses [ 8 ], childhood diseases [ 9 ], or COVID [ 10 ] become unavailable. Canadian Pharmacist Association Drug shortages survey of pharmacists. Table 2 Importance of the variables seen in the models, averaged across all IGs. Kuhn M, Wickham H Tidymodels: a collection of packages for modeling and machine learning using tidyverse principles. Pharmacists are responsible for the front-line delivery of drugs to patients, and they must be able to manage drug shortages to ensure continuity of care.
