Physicians’ acceptance of pharmacists’ interventions in daily hospital practice

Background The physicians’ acceptance rate of pharmacists’ interventions to improve pharmacotherapy can vary depending on the setting. The acceptance rate of interventions proposed by pharmacists located in the hospital pharmacy over the telephone and factors associated with acceptance are largely unknown. Objective To determine the physicians’ acceptance rate of pharmacists’ interventions proposed over the telephone in daily hospital practice and to identify factors associated with acceptance. Setting A retrospective case–control study was performed concerning adult patients admitted to a university hospital in the Netherlands. Method Pharmacists’ interventions, based on alerts for drug–drug interactions and drug dosing in patients with renal impairment, recorded between January 2012 and June 2013 that were communicated over the telephone were included. Factors associated with physicians’ acceptance were identified with the use of a mixed-effects logistic model. Main outcome measure The primary outcome was the proportion of accepted interventions. Results A total of 841 interventions were included. Physicians accepted 599 interventions, resulting in an acceptance rate of 71.2%. The mixed-effects logistic model showed that acceptance was significantly associated with the number of prescribed drugs (16 to ≤ 20 drugs ORadj 1.88; 95% CI 1.05–3.35, > 20 drugs ORadj 2.90; 95% CI 1.41–5.96, compared to ≤ 10 drugs) and the severity of the drug-related problem (problem without potential harm ORadj 6.36; 95% CI 1.89–21.38; problem with potential harm OR 6.78; 95% CI 2.09–21.99, compared to clinically irrelevant problems), and inversely associated with continuation of pre-admission treatment (ORadj 0.55; 95% CI 0.35–0.87). Conclusion Over the study period, the majority of pharmacists’ interventions proposed over the telephone were accepted by physicians. The probability for acceptance increased for patients with an increasing number of medication orders, for clinically r

A cost-benefit analysis of hospital-wide medication reviews: a period prevalence study

Background For specific medical specialties it has been shown that clinical pharmacists can have a beneficial effect on the reduction of drug-related problems by performing medication reviews. However, little is known on the cost–benefit ratio of hospital-wide implementation of medication reviews. Aim To investigate the effect of conducting hospital-wide medication reviews on the detection and resolution of drug-related problems, and to calculate the cost–benefit ratio of the intervention. Method In this observational prospective period prevalence study, medication reviews were conducted during five consecutive working days in a Dutch university hospital. Patients admitted for more than 24 h were included. The cost–benefit ratio of conducting the medication reviews was calculated by dividing the total costs by the total savings. Results In 622 medication reviews, 709 potential drug-related problems (1.1 per patient) were detected. T

Prescription errors in older individuals with an intellectual disability: Prevalence and risk factors in the Healthy Ageing and Intellectual Disability Study

Prescribing pharmacotherapy for older individuals with an intellectual disability (ID) is a complex process, possibly leading to an increased risk of prescription errors. The objectives of this study were (1) to determine the prevalence of older individuals with an intellectual disability with at least one prescription error and (2) to identify potential risk factors for these prescription errors (age, gender, body mass index (BMI), frailty index, level of intellectual disability and living situation). The study population consisted of 600 older (≥50 years) individuals with an ID using one or more drugs who were randomly selected from the study cohort of the Healthy Ageing and Intellectual Disability (HA-ID) Study. The medication used at the time of measurement was screened for errors by a hospital pharmacist/clinical pharmacologist and a Master's student pharmacy using consensus methodology. Participants with one or more prescription errors were compared to participants without prescription errors by multivariate logistic regression to identify potential risk factors. The prevalence of individuals with one or more prescription errors was 47.5% (285 of 600 individuals; 95% confidence interval (CI) 43-52%). Relevant errors, defined as errors that actually do require a change of pharmacotherapy, were identified in 26.8% of the individuals (161 of 600 individuals; 95% CI 23-30%). Higher age (adjusted odds ratio (ORadj) 1.03; 95% CI 1.01-1.06), less severe intellectual disability (moderate: ORadj0.48; 95% CI 0.31-0.74 and severe: ORadj0.56; 95% CI 0.32-0.98), higher BMI (ORadj1.04; 95% CI 1.01-1.08), higher frailty index (0.39-0.54: ORadj2.4; 95% CI 1.21-4.77 and ≥0.55: ORadj3.4; 95% CI 1.03-11.02), polypharmacy (ORadj8.06; 95% CI 5.59-11.62) and use of medicines acting on the central nervous system (ORadj3.34; 95% CI 2.35-4.73) were independently associated with the occurrence of prescription errors. Interventions targeted to high risk patients should be designed and implemented to improve pharmacotherapy in older individuals with an intellectual disability

Medication review using a Systematic Tool to Reduce Inappropriate Prescribing (STRIP) in adults with an intellectual disability: A pilot study

A Systematic Tool to Reduce Inappropriate Prescribing (STRIP), which includes the Screening Tool to Alert doctors to Right Treatment (START) and the Screening Tool of Older Peoples' Prescriptions (STOPP), has recently been developed in the Netherlands for older patients with polypharmacy in the general population. Active involvement of the patient is part of this systematic multidisciplinary medication review. Although annual review of pharmacotherapy is recommended for people with an intellectual disability (ID), a specific tool for this population is not yet available. Besides, active involvement can be compromised by ID. Therefore, the objective of this observational pilot study was to evaluate the process of medication review using STRIP in adults with an ID living in a centralized or dependent setting and the identification of drug-related problems using this tool. The study was performed in three residential care organizations for ID. In each organization nine clients with polypharmacy were selected by an investigator (a physician in training to become a specialized physician for individuals with an ID) for a review using STRIP. Clients as well as their legal representatives (usually a family member) and professional caregivers were invited to participate. Reviews were performed by an investigator together with a pharmacist. First, to evaluate the process time-investments of the investigator and the pharmacist were described. Besides, the proportion of reviews in which a client and/or his legal representative participated was calculated as well as the proportion of professional caregivers that participated. Second, to evaluate the identification of drug-related problems using STRIP, the proportion of clients with at least one drug-related problem was calculated. Mean time investment was 130 minutes for the investigator and 90 minutes for the pharmacist. The client and/or a legal representatives were present during 25 of 27 reviews (93%). All 27 professional caregivers (100%) were involved. For every client included at least one drug-related problem was identified. In total 127 drug-related problems were detected, mainly potentially inappropriate or unnecessary drugs. After six months, 15.7% of the interventions were actually implemented.Medication review using STRIP seems feasible in adults with an ID and identifies drug-related problems. However, in this pilot study the implementation rate of suggested interventions was low. To improve the implementation rate, the treating physician should be involved in the review process. Besides, specific adaptations to STRIP to address drug-related problems specific for this population are required
