Evaluation of a multifaceted medication review in older patients in the outpatient setting: a before-and-after study.

BACKGROUND: The prevalence of medication-related emergency department visits and acute hospital admissions in older patients is rising due to the ageing of the population and increasing prevalence of multimorbidity and associated polypharmacy. AIM: To explore whether a combined medication review performed in the outpatient setting reduces the number of medication-related emergency department visits and hospital (re)admissions. METHOD: All consecutive patients visiting the geriatric outpatient clinic underwent a multifaceted medication review (i.e. evaluation by at least a geriatrician, and/or pharmacist and use of clinical decision support system). Subsequently, we analysed the number of, and reason for, emergency department visits, acute hospital admissions and readmissions in the year prior to and the year following the index-date (date of first presentation and medication review). RESULTS: A multifaceted medication review reduced the number of potentially medication-related emergency department visits (38.9% vs. 19.6%, p < 0.01), although the total number of ED visits or acute hospital admissions per patient in the year before and after medication review did not differ. CONCLUSION: A multifaceted medication review performed in the outpatient clinic reduced the number of potentially medication-related emergency department visits and could therefore reduce negative health outcomes and healthcare costs.

Additional value of a triggerlist as selection criterion in identifying patients at high risk of medication-related hospital admission: a retrospective cohort study.

BACKGROUND: Of all hospital admissions in older patients, 10-30% seem to be medication-related. However, medication-related admissions are often unidentified in clinical practice. To increase the identification of medication-related hospital admissions in older patients a triggerlist is published in the Dutch guideline for polypharmacy. AIM: To assess whether the triggerlist has value as selection criterion to identify patients at high risk of medication-related hospital admissions. METHOD: This retrospective cohort study was carried out in 100 older (≥ 60 years) patients with polypharmacy and having two triggers from the triggerlist. The admissions were assessed as either possibly or unlikely medication-related according to the Assessment Tool for identifying Hospital Admissions Related to Medications. RESULTS: Of all the admissions 48% were classified as possibly medication-related. Patients with a possible medication-related hospital admission were more likely to have an impaired renal function (p = 0.015), but no differences with regard to age, sex, comorbidity or number of medicines were found. CONCLUSION: The high prevalence of medication-related hospital admissions, suggests the triggerlist may have added value as selection criterion in a cohort of older patients with polypharmacy and can be used to improve the identification of a population at high risk of medication-related hospital admissions.

Medication-related hospital admissions and readmissions in older patients: an overview of literature.

Background The number of medication related hospital admissions and readmissions are increasing over the years due to the ageing population. Medication related hospital admissions and readmissions lead to decreased quality of life and high healthcare costs. Aim of the review To assess what is currently known about medication related hospital admissions, medication related hospital readmissions, their risk factors, and possible interventions which reduce medication related hospital readmissions. Method We searched PubMed for articles about the topic medication related hospital admissions and readmissions. Overall 54 studies were selected for the overview of literature. Results Between the different selected studies there was much heterogeneity in definitions for medication related admission and readmissions, in study population and the way studies were performed. Multiple risk factors are found in the studies for example: polypharmacy, comorbidities, therapy non adherence, cognitive impairment, depending living situation, high risk medications and higher age. Different interventions are studied to reduce the number of medication related readmission, some of these interventions may reduce the readmissions like the participation of a pharmacist, education programmes and transition-of-care interventions and the use of digital assistance in the form of Clinical Decision Support Systems. However the methods and the results of these interventions show heterogeneity in the different researches. Conclusion There is much heterogeneity in incidence and definitions for both medication related hospital admissions and readmissions. Some risk factors are known for medication related admissions and readmissions such as polypharmacy, older age and additional diseases. Known interventions that could possibly lead to a decrease in medication related hospital readmissions are spare being the involvement of a pharmacist, education programs and transition-care interventions the most mentioned ones although controversial results have been reported. More research is needed to gather more information on this topic.
