RESUMO
Objective:To investigate the status quo of potentially inappropriate medication (PIM) among elderly hypertensive patients in community general practice clinic and related influencing factors.Methods:A total of 767 prescriptions for elderly hypertensive patients in a community health service center in Beijing from October 2020 to August 2021 were reviewed. The prevalence of PIM was assessed based on the criteria of potentially inappropriate medications for older adults in China(2017). Logistic regression analysis was employed to analyze the influencing factors for PIM. Results:The survey showed that 198 elderly patients had PIM with 244 person-doses. The top three drugs with high rate of PIM were benzodiazepine-estazolam (64 person-doses), clopidogrel (53 person-doses) and insulin (35 person-doses). Univariate analysis showed that PIM was significantly associated with types of medication;and underlying diseases hypertension with hyperlipidemia, coronary heart disease, type 2 diabetes, osteoarthritis, upper respiratory tract infection and insomnia (χ 2=82.58, 13.65, 17.74, 7.52, 10.34, 68.19,respectively,all P<0.05). Multivariate logistic regression analysis showed that the types of medication, hypertension complicated with upper respiratory tract infection, and insomnia were independent influencing factors for PIM ( OR=1.55, 2.47, 9.05; P<0.05). Conclusion:The study shows that PIM is more common in elderly hypertensive patients in community general practice clinics,which is associated with types of medication, hypertension complicated with upper respiratory tract infection and insomnia. It is suggested that general practitioner working in community clinics should be aware of PIM, minimize the number of prescription drugs, and choose new drugs or non-drug treatments to reduce the occurrence of PIM.
RESUMO
OBJECTIVE: To investigate and analyze the potential inappropriate medication(PIM) in elderly hospitalized patients in our hospital, explore the related risk factors, and analyze the use of PIM involved drugs in different departments, so as to provide reference for the formulation of medication manuals for the elderies in different departments and for further standardizing the use of drugs in elderly patients. METHODS: The medical advice for elder patients(≥65 years old)hospitalised from January to October 2017 in our hospital was collected. Beers criteria of American Geriatrics Association 2019 was used as the reference to investigate and analyze PIM. And the risk factors of PIM were analyzed by logistic regression. RESULTS: The average age of 12 756 elderly hospitalized patients was (74.13±6.88) years and the average number of diseases per patient was (3.22±2.09). For each patient, (4.79±3.76) kinds of medicines were used. According to the 2019 Beers criteria, the incidence of PIM was 20.00%. Among them, the central nervous system medications(6.41%, 818/12 756) (estazolam tablets, alprazolam tablets) were the most frequently used. Data of PIM occurrence in different departments showed that the PIM incidence was higher in rheumatology, geriatrics, rehabilitation, anesthesia surgery and oncology departments. In addition, logistic regression analysis showed that gender, age, the number of combined medications and diseases, and length of stay were all potential risk factors for PIM. CONCLUSION: The incidence of PIM in elderly hospitalized patients in our hospital is high. The rational drug use in elderly patients needs to be improved.
RESUMO
Objective The proportion of multiple drugs and the irrational use of drugs increased significantly in the elderly patients (over 80 years). This study aimed to investigate the occurrence of potentially inappropriate medication (PIM) and analyzed the possible reasons related to PIM in elderly patients. Methods In this study,918 cases from Cadre Ward I of Research Center for Geriatrics of Nanjing General Hospital of Nanjing Military Region were selected from January to December in 2016. According to the Beers Criteria (Version 2015),we evaluated PIM in four subtypes,type 1 that is not related to the state of disease in elderly patients, type 2 that is related to the state of disease in elderly patients,type 3 which should be used carefully,and type 4 which is the inappropriate combination of non-anti-infective Drugs. The PIM influence factors were analyzed by logistic regression analysis. Results There are 521 cases (56.75%) of type 1 PIM. The first 3 drugs are Short and medium acting benzodiazepams,PPI and long acting benzodiazepams. There are 206 cases (22.4%) of type 2 PIM. The first 2 drugs are drugs associated with insomnia (oral hyperemia, stimulants, theo-phylline and caffeine) and drugs associated with dementia or cognitive impairment (anti-cholinergic drugs and H2 receptor antago-nists). There are 834 cases (90.85%) of type 3 PIM,which should be used carefully and 45 cases(4.90%) of type 4 PIM.45 cases (4.90%) of non-anti-infective drugs should be avoid or reduced as much as possible in consideration of renal function. The number of combined drug use(OR=5.331,95% CI:3.549-8.009),the age(OR=1.171,95% CI:1.093-1.249),the Chalson's comorbidity index (OR=1.964,95% CI:1.477-2.450) are risk factors of PIM. Conclusion The incidence of potentially inappropriate use of drugs is high among the elderly patients. Reducing the number of combined drugs is an important measure to avoid the occurrence of PIM in elderly patients.
