Abstract

Objectives: To assess the status of outpatient prescriptions in elderly patients using the STOPP tool and to investigate some factors related to the PIM index at Vinh Medical University Hospital. Methods: A cross-sectional prospective study, the research materials are prescriptions, outpatient medical records of patients with aged 60 years and older at the medical examination department of Vinh Medical University Hospital. Results: The rate of encountering potentially inappropriate drugs according to STOPP 2014 on outpatient prescriptions in the study was 18.35%, of which 21 types of PIM were recorded, the most common was using Aspirin in patients with a history of peptic ulcer without PPIs (20.34%), sulphonylureas with long duration of action such as glibenclamide, glimepiride (13.65%), PPI for treatment of uncomplicated peptic ulcer or ulcer oesophagitis at full dose >8 weeks (11.86%). Factors that increase the likelihood of encountering PIM according to STOPP 2014 include multiple pharmacology OR=2,308 (CI95%=1,130-4.711, p=0.022), digestive system disease OR=2.694 (CI95%=1,353-5,364, p=0.005 ) and circulatory disease OR=2,828 (CI95%=1.287-6.215, p=0.010). In which cardiovascular disease is the factor that has the strongest influence on the likelihood of having PIM according to STOPP 2014, the group of patients with cardiovascular disease has a 2.8 times higher risk of PIM than the group without cardiovascular disease. Conclusion: The study indicated that the rate of potentially inappropriate prescription (PIM) was 18.35%. Limit multidrug prescribing in elderly patients, especially 5 or more drugs due to the increased likelihood of PIM. Patients with cardiovascular or gastrointestinal disease are more likely to experience PIM.
