Background: Medications are used to treat, cure, or relieve symptoms of diseases, but there is a risk with the use of medications. Drug-related-problems are known to increase morbidity and mortality. Incorrect medical list and discrepancies in these lists can lead to drug-related problems as side effects, hospitalization, non-compliance, drug interactions and overtreated or undertreated patients. Discrepancies can be for example: more prescriptions than necessary, outdated prescriptions, i.e., medicines that will not be used, prescriptions with incorrect dosing and missing prescriptions i.e., medicines used by patients that cannot be seen in the medication list.
Purpose: The aim of this study was to investigate discrepancies in the Swedish prescription list "My saved prescriptions at the pharmacy". The secondary aim was to investigate how common it is to use this prescription list or the dosage label on the medicine packaging to know which medicines to use and which dosage.
Methods: The data collection was performed by four pharmacy students at seven pharmacies in Sweden over a period of three weeks during Jan-Feb. 2021 where the prescription list was investigated together with patients to identify any discrepancies. The study included patients who was over 18 years old, spoke Swedish, had three or more prescribed drugs, and agreed to participate.
Results A total of 215 patients were interviewed, where 61% had one or more discrepancies in their medication list. A total of 1717 prescriptions were analyzed, of which 10% were double prescriptions (n = 167), 8% outdated prescriptions (n = 141) and 3% prescriptions with the wrong dosage (n = 42). When analyzing the primary sources of information used by patients to know which medicine to use, the printout of the list "my saved prescriptions at the pharmacy” dominated (n = 72). Most used information source to know drug dosage was the dosage label on the medicine packaging (n = 112).
Conclusions: It is important to have an updated and correct information in the medication list, to prevent drug-related-problems caused by discrepancies. It becomes even more important when we see that the medication list "My saved prescriptions at the pharmacy" and dosage label (containing the same information in the medication list), are the most used primary sources by patients to know which drug to use and in what dosage. Finally, results show a relationship between the number of prescribed drugs and the number of discrepancies that occur, and therefore we see more discrepancies in elderly patients who are usually ill and are being treated for several diseases.
There are opportunities for further research to study e.g., which drug-related-problems are caused by discrepancies in the medication list as well as the degree of danger in these problems.
