The challenges of drug shortages in the Canadian hospital pharmacy supply chain — a systematic literature review.

Aim: The aim of this paper is to highlight current knowledge gaps that exist with regard to the factors which affect the supply chain, and the inventory management strategies that are utilized by hospital pharmacies in Canada which could lead to drug shortages. Subject and method: This research implements an optimal SLR (systematic literature review) method on drug shortages based on CHPSC (Canadian hospital pharmacy supply chain) literature and databases. This makes it possible to perform a wide review of Canadian hospital pharmacies and understand how continued disruption occurred in this process and caused drug shortages. Results and conclusion: The result of this research is contained in a systematic search methodology which consists of four main tasks, namely: a) building an optimal review process, b) defining search procedures, c) validating the search procedures, and d) conducting literature search. Furthermore, the researchers conducted a SLR which unveiled issues and factors such as raw materials availability and increases in demand which cause drug shortages. In conclusion, the proposed systematic methodology seeks to highlight possible solutions to the supply chain management issues which could cause drug shortages in Canada. Various solutions are proposed and explored, with the relevant information being obtained from studies conducted on how to mitigate the impact on supply chain management. [ABSTRACT FROM AUTHOR]
