Information on actual medication use and drug-related problems in older patients: questionnaire or interview?

ABSTRACT: Information on medication use and drug-related problems is important in the preparation of clinical medication reviews. Critical information can only be provided by patients themselves, but interviewing patients is time-consuming. Alternatively, patient information could be obtained with a questionnaire.In this study the agreement between patient information on medication use and drug-related problems in older patients obtained with a questionnaire was compared with information obtained during an interview.General practice in The Netherlands.A questionnaire was developed to obtain information on actual medication use and drug-related problems. Two patient groups ?65 years were selected based on general practitioner electronic medical records in nine practices; I. polypharmacy and II. ?1 predefined general geriatric problems. Eligible patients were asked to complete the questionnaire and were interviewed afterwards.Agreement on information on medication use and drug-related problems collected with the questionnaire and interview was calculated.Ninety-seven patients participated. Of all medications used, 87.6 % (95 % CI 84.7-90.5) was reported identically in the questionnaire and interview. Agreement for the complete medication list was found for 45.4 % (95 % CI 35.8-55.3) of the patients. On drug-related problem level, agreement between questionnaire and interview was 75 %. Agreement tended to be lower in vulnerable patients characterized by ?4 chronic diseases, ?10 medications used and low health literacy.Information from a questionnaire showed reasonable agreement compared with interviewing. The patients reported more medications and drug-related problems in the interview than the questionnaire. Taking the limitations into account, a questionnaire seems a suitable tool for medication reviews that may replace an interview for most patients.

Project description:BackgroundCompared with those without dementia, older patients with dementia admitted to acute care settings are at higher risk for triad combination of polypharmacy (PP), potentially inappropriate medication (PIM), and drug-drug interaction (DDI), which may consequently result in detrimental health. The aims of this research were to assess risk factors associated with triad combination of PP, PIM and DDI among hospitalized older patients with dementia, and to assess prevalence and characteristics of PP, PIM and DDI in this population.MethodsIn this retrospective cross-sectional study, 416 older inpatients diagnosed with dementia and referred for specialist geriatric consultation at a tertiary hospital in Brisbane, Australia during 2006-2016 were enrolled. Patients were categorized into two groups according to their exposure to the combination of PP, PIM and DDI: 'triad combination' and 'non-triad combination'. Data were collected using the interRAI Acute Care (AC) assessment instrument. Independent risk factors of exposure to the triad combination were evaluated using bivariate and multivariate logistic regression analyses.ResultsOverall, 181 (43.5%) were classified as triad combination group. The majority of the population took at least 1 PIM (56%) or experienced at least one potential DDI (76%). Over 75% of the participants were exposed to polypharmacy. The most common prescribed PIMs were antipsychotics, followed by benzodiazepines. The independent risk factors of the triad combination were the presence of atrial fibrillation diagnosis and higher medications use in cardiac therapy, psycholeptics and psychoanaleptics.ConclusionsThe exposure to triad combination of PP, PIM and DDI are common among people with dementia as a result of their vulnerable conditions and the greater risks of adverse events from medications use. This study identified the use of cardiac therapy, psycholeptics and psychoanaleptics as predictors of exposure to PP, PIM and DDI. Therefore, use of these medications should be carefully considered and closely monitored. Furthermore, comprehensive medication reviews to optimize medication prescribing should be initiated and continually implemented for this vulnerable population.

Project description:Medication-related problems (MRPs) are an important healthcare problem. This study aimed at reviewing the published literature in Ethiopia to estimate the prevalence of MRPs and to summarize associated factors. A comprehensive systematic search was conducted in PubMed, EMBASE, CINAHL, Scopus, Google Scholar, and Google databases from inception to April 2020. Articles that addressed MRPs were eligible for inclusion. Article screening, data extraction, and study quality analysis were performed independently by two reviewers. Studies targeting specific disease condition were considered as specific, while the remaining were nonspecific. The prevalence of MRPs was then computed in medians and interquartile ranges (IQR), while associated factors were summarized in a table. Of the thirty-two studies included in this review, the majority of them (n = 24) targeted MRPs, while the remaining studies (n = 8) investigated adverse drug reactions (ADRs). Studies varied in the study design, study population, and definition of MRPs and ADRs used. The overall median prevalence was 70.8% (IQR = 61.0-80.2) with a range of 16.0% to 88.7%. The median prevalence of MRPs in specific and nonspecific patients was 71.2% (IQR = 60.7-71.2) and 69.3% (IQR = 60.7-82.0), respectively. In addition, a median of 36.6% (IQR = 10.0-85.7) of patients experienced ADRs. Indication-related and effectiveness-related MRPs were commonly reported in both specific and nonspecific patients, while noncompliance MRPs were more prevalent among specific patients than nonspecific patients. Increasing age, presence of co-morbidity, and an increasing number of drugs were the commonly identified contributing factors of MRPs. The review showed that more than two-thirds of the study participants developed MRPs. Hence, an integrated approach should be designed to improve the optimal use of pharmacotherapy to reduce the burden of MRPs. Further, future research should be undertaken to prepare cost-effective and efficient prevention mechanisms to reduce or halt the development of MRPs.

Project description:ObjectivesThe Drug-Associated Risk Tool (DART) has been developed as a self-administered questionnaire for patients with the aim of stratifying patients according to their risk of drug-related problems (DRPs). We aimed to validate the ability of the questionnaire to distinguish between hospitalised patients showing lower and higher numbers of DRPs.DesignCross-sectional study assessing the questionnaire's concurrent criterion validity.SettingFive geriatric and the associated physical and neurological rehabilitation wards of a Swiss regional secondary care hospital with 617 beds.ParticipantsWe recruited 110 patients from a total of 437 admissions. Exclusion criteria were insufficient knowledge in spoken or written German, medical conditions preventing meaningful conversations and already receiving pharmacy services.InterventionsComprehensive pharmacist-led clinical medication reviews were performed, including patient interviews, to identify potential and manifest DRPs. A cluster analysis was conducted to assess the discriminatory potential of the DART to group patients according to number (low and high) of identified DRPs. A subsequent discriminatory function analysis was performed to reduce the number of items. We determined which DART items may be used to trigger what type of medication review.ResultsRecruited patients had a median age of 79 years and were prescribed a median of 11 drugs. Patients with a median DART score of 10 and a median of 3 DRPs represented one cluster, whereas patients with a median DART score of 15 and a median of 8 DRPs represented another cluster. Discriminatory function analysis reduced the questionnaire to five items with a moderate to strong correlation with the number of DRPs per patient (Spearman's rank correlation ?=0.44). Additional items were associated with patients benefiting from interviews.ConclusionsAs a self-administered questionnaire for patients, the DART may be used to stratify hospitalised non-acute older patients in groups of having low and high likelihood of DRPs. The analyses showed that a short form of the DART can be used instead of the full tool to identify older inpatients at risk for DRPs. Additional eight items from the DART may be used to initiate additional clinical pharmacy services. The linkage between certain DART questions and type of medication review enables pharmacist resource allocation.
