Study Protocol for the Evaluation of Multidisciplinary Medication Reconciliation Service in Adult Patients Undergoing Thoracic and Cardiovascular Surgery (The MERITS Study): A Single-Center Controlled before-and-after Study.

Medication reconciliation (MR), which is widely implemented worldwide, aims to improve patient safety to reduce the medication errors during care transition. Despite its widespread use, MR has not yet been implemented in the Republic of Korea, and its effectiveness has not been studied. We aimed to evaluate the impact of a multidisciplinary MR service in older patients undergoing thoracic and cardiovascular surgery. This is a single-center, prospective, controlled, before-and-after study of adult patients taking at least one chronic oral medication. Depending on the period of each patient's participation, they will be allocated to an intervention group or control group. Patients in the intervention group will receive multidisciplinary MR, and those in the control group will receive usual care. The primary outcome is to assess the impact of the MR service on medication discrepancies between the best possible medication history and medication orders at care transition. Secondary outcomes include the incidence rate of medication discrepancies at each transition, the discrepancy rate between the sources of information, the impact of MR on medication appropriateness index score, drug-related problems, 30-day mortality, the emergency department visit rate, readmission rate after discharge, the rate and acceptability of pharmacists' intervention during hospitalization, and patients' satisfaction.

Medication Review in Turkish Older Adults at Community Pharmacy: A Pilot Study by Using Medication Appropriateness Index

Objective: The study aimed to evaluate medication review in older adults (≥65 years) at a community pharmacy by identifying the prevalence of potentiality inappropriate medication and calculating medication appropriateness index.
 
 Methods: This descriptive study was carried out in a community pharmacy for six months. The older adults (≥65 years) using one or more medications were included. During clinical pharmacist-led medication review; the medication appropriateness index was calculated for each medication of older adults. Potentially inappropriate medications were evaluated according to the 2019 American Geriatrics Society Beers Criteria®.
 
 Result: Among a hundred older adults, 46.0% were female. The median age of the patients was 75.5 (IQR, 68.0-78.8). The median number of medications was 9.0 (7.0-10.0). Polypharmacy has been detected in 97.0% of the patients. At least one potentially inappropriate medication was detected in 63.0% of them. The median score of medication appropriateness index score was 53.0 (IQR: 38.6-67.9).
 
 Conclusion: To best our knowledge, this is the first study of clinical pharmacist-led medication review by calculating the medication appropriateness index carried out at a community pharmacy in Turkey. There was a high rate of potentially inappropriate medication with a higher score of medication appropriateness in older adults. This study highlights the importance of medication review led by the clinical pharmacist at community pharmacy to optimize medication usage in older adults.

Minding the gap-an examination of a pharmacist case management medicines optimisation intervention for older people in intermediate care settings.

Whilst attention has been paid within the literature to examining potentially inappropriate prescribing (PIP) for older adults in a variety of care settings, less is known about the extent within intermediate care. Furthermore, few studies have examined the utility of clinical pharmacist involvement in this care context. Determine the prevalence of PIP in intermediate care (IC) settings in Northern Ireland (NI), explore the utility of a novel pharmacist case management model at reducing PIP and to examine the association with subsequent healthcare utilisation. Secondary analysis of prospective data (N=532) collected during a medicines optimisation pharmacist case management model in three intermediate care sites in NI. Independent prescriber pharmacists delivered the intervention. Variability in Medication Appropriateness Index score change (ΔMAI) from admission to discharge was examined using multivariate linear regression analysis. Multivariate logistic and Poisson regressions were used to examine the association between ΔMAI and likelihood and numbers of unplanned hospital readmissions within 30 and 90 days of IC discharge. PIP was highly prevalent (89.5%) at baseline with significant reductions in MAI score achieved from admission (Median=14) to discharge (Median=0) (Z=-18.28, p<.001). The prevalence of PIP at discharge was 7.8%. No relationship was observed between ΔMAI score and unplanned hospital readmission. Those who received at least one educational intervention were less likely to be readmitted within 30 days of IC discharge (OR=0.15, 95% CI 0.03, 0.71, p<.001). Baseline healthcare utilisation consistently predicted healthcare utilisation post-IC discharge. Drug-related problems persist for many older adults following acute care discharge and intermediate care may provide an ideal location for medicines optimisation interventions.

Improving Appropriate Prescribing For Geriatric Patients Using a Clinical Decision Support System.

Purpose: Polypharmacy is a known risk factor for potentially inappropriate prescribing. Recently there is an increasing interest in clinical decision support systems (CDSS) to improve prescribing. The objective of this study was to evaluate the impact of a CDSS, with the START-STOPP criteria as main content in the setting of a geriatric ward. Endpoints were 1) appropriateness of prescribing and 2) acceptance rate of recommendations. Methods: This prospective study comparing the use of a CDSS with usual care involved patients admitted to geriatric wards in two teaching hospitals in the Netherlands. Patients were included from January to May 2017. The medications of 64 patients in the first six weeks was assessed according to the current standard, whereas the medications of 61 patients in the second six weeks were also assessed by using a CDSS. Medication appropriateness was assessed with the Medication Appropriateness Index (MAI). Results: The medications of 125 patients (median age 83 years) were reviewed. In both the usual care group and the intervention group MAI scores decreased significantly from admission to discharge (within group analyses, p<0.001). This effect was significantly larger in the intervention group (p<0.05). MAI scores at discharge in the usual care group and the intervention group were respectively 9.95±6.70 and 7.26±5.07. The CDSS generated 193 recommendations, of which 71 concerned START criteria, 45 STOPP criteria, and 77 potential interactions. Overall, 31.6% of the recommendations were accepted. Conclusion: This study shows that a CDSS to improve prescribing has additional value in the setting of a geriatric ward. Almost one third of the software-generated recommendations were interpreted as clinically relevant and accepted, on average one per patient.

Clinical pharmacist evaluation of medication inappropriateness in a geriatric hospital

Potentially inappropriate prescribing (PIP) in elderly patients is highly prevalent and is associated with an increased risk of adverse drug events, morbidity, and mortality. Accordingly, this study aimed to evaluate the PIP encountered in a geriatric setting and to highlight the role of the clinical pharmacists in this context. A retrospective observational study was conducted during March and April 2018 in an elderly daycare in Beirut area. Patients' files were screened to evaluate each patient's clinical status using a developed tool that included the Medication Appropriateness Index. Statistical analysis was performed using SPSS (version 20). The results were considered significant at P<0.05. The results showed a high incidence of hypertension, schizophrenia, and diabetes among the studied sample with percentages of 41.7%, 35.3%, and 26.6%, respectively. As for the PIP, drug therapy duration and cost were the most encountered problems followed by medication indication, dosage, and drug-drug interaction. Moreover, PIP increased with the number of prescribed medications (P<0.05). Proton pump inhibitors, low dose aspirin, and antidiabetic medications' users had a significantly higher Medication Appropriateness Index score as compared to non-users. As a conclusion, suboptimal care is proved in this study empowering the collaboration between clinical pharmacists and physicians in minimizing the PIPs in elderly daycares.

Influence of a ward-based pharmacist on the medication quality of geriatric inpatients: a before\u2013after study

Background Despite several international studies demonstrating that ward-based pharmacists improve medication quality, ward pharmacists are not generally established in German hospitals. Aim We assessed the effect of a ward-based clinical pharmacist on the medication quality of geriatric inpatients in a German university hospital. Method The before-after study with a historic control group was conducted on the geriatric ward. During the control phase, patients received standard care without the involvement of a pharmacist. The intervention consisted of a clinical pharmacist providing pharmaceutical care from admission to discharge. Medication quality was measured on admission and discharge using the Medication Appropriateness Index (MAI). A linear regression analysis was conducted to calculate the influence of the intervention on the MAI. Results Patients in the intervention group (n = 152, mean 83 years) were older and took more drugs at admission compared to the control group (n = 159, 81 years). For both groups, the MAI per patient improved significantly from admission to discharge. Although the intervention did not influence the summated MAI score per patient, the intervention significantly reduced the MAI criteria Dosage (p = 0.006), Correct Directions (p = 0.016) and Practical Directions (p = 0.004) as well as the proportion of overall inappropriate MAI ratings (at least 1 of 9 criteria inappropriate) (p = 0.015). Conclusion Although medication quality was already high in the control group, a ward-based clinical pharmacist could contribute meaningfully to the medication quality on an acute geriatric ward.

How to Improve Healthcare for Patients with Multimorbidity and Polypharmacy in Primary Care: A Pragmatic Cluster-Randomized Clinical Trial of the Multipap Intervention

Background: key problem in multimorbidity (MM) is polypharmacy (PP), which is associated with increased risks for partly preventable adverse outcomes. The Ariadne principles support primary care consultations that aim to prioritize and share appropriate treatment goals in MM. The aim of this study is to evaluate the effectiveness of the complex MULTIPAP intervention, which implements the Ariadne principles in a primary care population of young-elderly patients with MM&PP, at improving the appropriateness of prescription. Methods: We conducted a pragmatic cluster randomized clinical trial in 38 family practices in Spain. Family physicians (FPs) were randomly allocated to continue usual care or to provide the MULTIPAP intervention based on the Ariadne principles. The latter consisted of two key components: FP training (eMULTIPAP) and FP–patient interviews. Patients aged 65-74 years with MM&PP were recruited. The primary outcome was the baseline-adjusted Medication Appropriateness Index (MAI) score at 6 months. Participants were not blinded to group assignment, but the analysis of outcomes was blinded. Secondary outcomes were quality of life (EQ-5D-5 L), patient perceptions of shared decision making (collaboRATE), use of health services, treatment adherence, and incidence of drug adverse events (all at 1 year). We analysed the primary outcome in the intention-to-treat population, the missing data being multiply imputed. We analysed outcomes using multi-level regression models, with FP as a random effect. Findings: Between 8 Nov 2016 and 31 Dec 2017, we recruited 117 FPs and 593 of their patients. Mean patient age was 69.7 (2.7) years, 55.8% were women, 60.5% belonged to social classes V-VI, and 28.7% had low self-reported income. In the intention-to-treat analysis, the between-group difference in mean MAI score after 6 months’ follow-up was -2.42 (95% CI -4.27 to -0.59) and between baseline and 12 months’ follow-up was -3.40 (95% CI -5.45 to -1.34). There were no significant differences in another secondary outcomes. Interpretation: The MULTIPAP intervention improved medication appropriateness stably over time. Differences in secondary outcomes were not significant.

Use of potentially inappropriate medications among older outpatients and inpatients in a tertiary care hospital in Malaysia.

Older individuals are seemingly having more medical conditions, which predispose them to a greater risk of polypharmacy. Potentially inappropriate medications (PIMs), including those having anticholinergic and sedative properties, are common in their prescriptions, often associated with functional decline and negative health outcomes. Thus, this study reports proportions of inappropriate drugs and drug burden exposures and its correlation with patient-reported outcomes (PROs) among cognitively intact older adults admitted to a ward or visiting the outpatient clinic at a tertiary care hospital in Malaysia. This cross-sectional study included data from 344 older (173 inpatients and 171 outpatients) patients, aged 60years and above, through validated questionnaires. Medication appropriateness was assessed via Medication Appropriateness Index (MAI) tool, whereas Beers and Screening Tool of Older Person's Potentially Inappropriate Prescribing (STOPP) criteria were used to evaluate PIMs and potentially inappropriate prescribing (PIP), respectively. The Drug Burden Index (DBI) and polypharmacy, as well as PROs, included Groningen Frailty Indicator (GFI), Katz Index of Independence in Activities of Daily Living (Katz ADL) and Older People's Quality of Life (OPQOL) were also evaluated. Overall, inpatients received significantly higher medications (6.90±2.70 vs 4.49±3.20) than outpatients. A significantly higher proportion of inpatients received at least one PIM (65% vs 57%) or PIP (57.4% vs 17.0%) and higher mean MAI score (1.76±1.08 and 1.10±0.34) and DBI score (2.67±1.28 vs 1.49±1.17) than outpatients. Inpatients had significantly higher total OPQOL (118.53 vs 79.95) and GFI score (5.44 vs 3.78) than outpatients. We only found significant correlations between GFI and DBI and total OPQOL and the number of PIMs. Proportions of PIMs and DBI exposure were significantly higher in an inpatient setting. No significant correlations between exposures to inappropriate medications or drug burden and PROs were observed.

Improvements in Antibiotic Appropriateness for Cystitis in Older Nursing Home Residents: A Quality Improvement Study With Randomized Assignment

ObjectiveTo determine the impact of an educational quality improvement initiative on the appropriateness of antibiotic prescribing restricted to uncomplicated cystitis in older noncatheterized nursing home residents. DesignQuality improvement study with randomized assignment. Settings and ParticipantsTwenty-five nursing homes in United States were randomized to the intervention or usual care group by strata that included state, urban/rural status, bed size, and geographic separation. MethodsA 12-month trial of a low-intensity multifaceted antimicrobial stewardship intervention focused on uncomplicated cystitis in nursing home residents vs usual care. The outcome was the modified Medication Appropriateness Index as assessed by a blinded geriatric clinical pharmacist and consisted of an assessment of antibiotic effectiveness, dosage, drug-drug interactions, and duration. ResultsThere were 75 cases (0.15/1000 resident days) in intervention and 92 (0.22/1000 resident days) in control groups with a probable cystitis per consensus guidelines. Compared with controls, there was a statistically nonsignificant 21% reduction in the risk of inappropriate antibiotic prescribing (nonzero Medication Appropriateness Index score rate 0.13 vs 0.21/1000 person days; adjusted incident rate ratio 0.79; 95% confidence interval 0.45‒1.38). There was a favorable comparison in inappropriateness of duration (77% vs 89% for intervention vs control groups, respectively; P = .0394). However, the intervention group had more problems with drug-drug interactions than the control group (8% vs 1%, respectively; P = .0463). Similarly, the intervention group had a nonsignificant trend toward more problems with dosage (primarily because of the lack of adjustment for decreased renal function) than the control group (32% vs 25%, respectively; P = .3170). Both groups had similar rates of problems with choice/effectiveness (44% vs 45%; P = .9417). The most common class of antibiotics prescribed inappropriately was quinolones (25% vs 23% for intervention versus control groups, respectively; P = .7057). Conclusions and ImplicationsA low-intensity intervention showed a trend toward improved appropriate antibiotic prescribing in nursing home residents with likely uncomplicated cystitis. Efforts to improve antibiotic prescribing in addition to the low-intensity intervention might include a consultant pharmacist in a nursing home to identify inappropriate prescribing practices.

Medication appropriateness on an acute geriatric care unit: the impact of the removal of a clinical pharmacist.

evidence is largely available indicating benefits to adding a pharmacist on acute care wards. The benefits of maintaining pharmacotherapeutic consultant services on a geriatric ward remain unexplored. to determine the impact of the removal of a clinical pharmacist from an acute geriatric ward on patients' Medication Appropriateness Index (MAI) scores, admission-related outcomes and drug burdens. researchers consulted the archives for records of patients admitted to the geriatric care unit before and after the pharmacist's withdrawal. The primary outcome of differential MAI scores and secondary outcomes of rehospitalisations, emergency department visits, durations of hospitalisation and differential drug count were compared pre- and post-intervention. An interrupted time series analysis regression model was used for the primary outcome. a total of 305 patients admitted before (n= 208) and after (n= 97) the pharmacist's withdrawal were included in the study. The intervention had a significant impact on the primary outcome, increasing the relative differential MAI score (adjusted mean) by 9.3 points (95% confidence interval 3.9-14.6). As for the secondary outcomes, differences in admission-related outcomes were non-significant but the mean differential drug count significantly increased post-intervention from 0.02 to 1.36 (P< 0.001). the removal of the pharmacist led to an increase in inappropriate drug prescription. Careful consideration should be given to decisions regarding the removal of the pharmacist from acute geriatric care teams.

MULTIPAP Study: Improving healthcare for patients with multimorbidity.

The steady rise in multimorbidity entails serious consequences for our populations, challenges healthcare systems, and calls for specific clinical approaches of proven effectiveness. The MULTIPAP Study comprises three sequential projects (MULTIPAP and MULTIPAP Plus RCTs, and the MULTIPAP Cohort). Results of MULTIPAP RCT are presented. To evaluate the effectiveness of a complex, patient-centred intervention in young-old patients with multimorbidity and polypharmacy. Pragmatic cluster-randomised clinical trial in a primary healthcare setting. GPs were randomly allocated to either conventional care or the MULTIPAP intervention based on the Ariadne Principles with two components: GPs e-training (that is, eMULTIPAP addresses specific, key concepts on multimorbidity, polypharmacy and shared decision-making) and GP-patient-centred interview. Young-old patients aged 65-74 years with multimorbidity and polypharmacy were included. difference in the Medication Appropriateness Index (MAI) after 6-month follow-up between groups. MAI, quality of life, patient perception, health services use, treatment adherence and cost-effectiveness after 12-month follow-up. 117 GPs from 38 Spanish primary health care recruited 593 patients randomly assigned to the intervention/control groups. Difference in MAI scores between groups in the intention-to-treat analysis after 6 months' follow-up: -2.42 (-4.27 to -0.59), P = 0.009 (adjusted difference in mean MAI score -1.81(-3.35 to -0.27), P = 0.021). not significant, including quality of life (adjusted difference in mean EQ-5D-5L (VAS) 2.94 (-1.39 to 7.28), P = 0.183, EQ-5D-5L (index) -0.006(-0.034 to 0.022), P = 0.689). The intervention significantly improved medication appropriateness. The observed quality of life improvement was not significant. GPs e-training in multimorbidity has shown to be feasible and well accepted by the professionals. Future studies may test whether this format facilitates implementation.

A Collaborative Medication Review Including Deprescribing for Older Patients in an Emergency Department: A Longitudinal Feasibility Study.

Medication review for older patients with polypharmacy in the emergency department (ED) is crucial to prevent inappropriate prescribing. Our objective was to assess the feasibility of a collaborative medication review in older medical patients (≥65 years) using polypharmacy (≥5 long-term medications). A pharmacist performed the medication review using the tools: Screening Tool of Older Persons’ potentially inappropriate Prescriptions (STOPP) criteria, a drug–drug interaction database (SFINX), and Renbase® (renal dosing database). A geriatrician received the medication review and decided which recommendations should be implemented. The outcomes were: differences in Medication Appropriateness Index (MAI) and Assessment of Underutilization Index (AOU) scores between admission and 30 days after discharge and the percentage of patients for which the intervention was completed before discharge. Sixty patients were included from the ED, the intervention was completed before discharge for 50 patients (83%), and 39 (61.5% male; median age 80 years) completed the follow-up 30 days after discharge. The median MAI score decreased from 14 (IQR 8-20) at admission to 8 (IQR 2-13) 30 days after discharge (p < 0.001). The number of patients with an AOU score ≥1 was reduced from 36% to 10% (p < 0.001). Thirty days after discharge, 83% of the changes were sustained and for 28 patients (72%), 1≥ medication had been deprescribed. In conclusion, a collaborative medication review and deprescribing intervention is feasible to perform in the ED.

An evaluation of medication appropriateness in pregnant women with coexisting illness in a tertiary care hospital.

Aim:Prescribing drugs during pregnancy needs careful consideration of benefit to the mother and risk to the fetus. Therefore, this study was conducted to evaluate the appropriateness of medications among pregnant women with coexisting illness in a tertiary care hospital, Western India.Materials and Methods:It was a hospital-based cross-sectional study conducted in the obstetrics and gynecology department of a tertiary care hospital. The study was conducted over a period of 12 months wherein data from 800 pregnant women suffering from any co-existing illness and being prescribed any medication apart from routine supplementation were analyzed. The Medication Appropriateness Index (MAI) was used to assess the appropriateness of medications. Higher MAI scores indicate more inappropriate prescribing.Results:Drugs which were most inappropriately prescribed with the highest average MAI scores were albendazole, itraconazole, injection amikacin, oxcarbazepine, warfarin, domperidone, propylthiouracil, and combiflam (ibuprofen + paracetamol). Diseases with the highest average MAI scores were anemia, Grave's disease, umbilical hernia, urinary tract infection, urticaria, allergic rhinitis, and preeclampsia. The MAI criteria which had the highest percentage of inappropriately prescribed medications were “cost of drugs,” “duration of therapy,” and “indication.”Conclusion:Potentially inappropriate prescribing was seen in the study with some of the common coexisting illness being treated with drugs which fared poorly on the MAI. The study has also highlighted areas in drug prescribing where scope for improvement exists. Further, it can act as a benchmark for comparison of future studies to evaluate medication appropriateness in pregnant women.

43 Addressing Polypharmacy in the Frail Older Person - the WIDE (Wholistic, Integrated, Deprescribing, Evaluation) Review

Abstract Background People are living longer, with more chronic conditions and are prescribed more medications according to disease specific guidelines. The WIDE Review is an innovative model of comprehensive medication review devised to treat the whole patient. Frail patients are twice as likely to be prescribed inappropriate medications and are more vulnerable to their harmful effects. Use of the STOPP/START criteria and the Medication Appropriateness Index (MAI) have been shown to improve patient outcomes. This study examined the impact and cost effectiveness of pharmacist led WIDE Reviews. Methods This quantitative prospective cohort study was conducted over 8 weeks in a Model 3 hospital. Inclusion criteria: inpatients age &gt; 65 years; prescribed &gt; 6 regular medications and screened positive for frailty (PRISMA 7 score &gt;3). Critically ill patients were excluded. Eligible patients were randomly allocated to intervention or control group. The intervention group received a pharmacist led WIDE Review: Wholistic (establishing patients' priorities), Integrated (collaborating with primary care providers), Deprescribing Evaluation of medication harms versus benefits. Medications were screened using the STOPP/START criteria and the MAI was calculated. In conjunction with the patients and their consultants, deprescribing plans were devised and communicated to their GPs and community pharmacists Results A total of 20 intervention and 20 control group patients were enrolled. Patient characteristics (age, sex and length of stay) were similar for both groups. 65% of STOPP and 62% of START criteria were addressed in the intervention group versus 12% and 5% respectively in the control group. In the intervention group 83 medications were stopped, 23 dose reduced and the total MAI score was reduced by 64%. Cost savings to the annual drug budget alone represented a 9:1 return on investment of hospital pharmacist time. Conclusion Pharmacists performing WIDE Reviews significantly improved medication appropriateness and realised compelling cost savings. A larger scale study of this innovative approach to medication review is planned.

Effect of pharmacist‐led medication review on medication appropriateness in older adults with chronic kidney disease

AbstractThis study evaluated the effect of pharmacist‐led review on medication appropriateness in 204 older patients with chronic kidney disease (CKD) admitted to an Australian hospital. Medication appropriateness was evaluated using the Medication Appropriateness Index (MAI) prior to medication review, after review (assuming all recommendations were accepted by physicians) and after outcome (acceptance/non‐acceptance) of recommendations. Overall, 95 patients (46%) received a medication review by pharmacists. The median (interquartile range) MAI score decreased significantly from a baseline of 7 (3–12) to 5 (2–10) after medication review (p &lt; 0.001) and to 6 (2–10) after the outcome of recommendations (p &lt; 0.01). The MAI score also decreased in patients with no medication review by a pharmacist from 6 (3–11) at admission to 5 (2–9) at discharge (p &lt; 0.001). MAI scores declined markedly in people with all pharmacist‐conducted medication review recommendations accepted (from 7 to 3; p &lt; 0.05). Reassuringly, hospitalisation alone improved medication appropriateness. However, pharmacist‐led medication review can further optimise medication appropriateness in older CKD patients, particularly when the recommendations are implemented.

Evaluation of a Pharmacist-Based Intervention to Reduce Readmissions in Geriatric High-Utilizer Patients: A Pilot Study.

The goal of this study was to determine if a pharmacist-led intervention to improve medication safety at hospital discharge reduced the number of hospital readmissions among geriatric high-utilizer patients. This study is the first to test a pharmacist-based intervention in a high-utilizer population. This was a quasi-experimental pilot study done at a safety-net hospital in the southeastern US. Fifty-seven patients 65 years old and older who were in the 95th percentile for number of hospital admissions in a year were included. On the day of discharge, one of the study pharmacists reviewed the discharge medication list and calculated the Medication Appropriateness Index (MAI) for each medication and reviewed for Beers Criteria. Any medication identified as potentially high-risk or inappropriate was flagged by the pharmacist and discussed with the team. The primary outcome was the number of admissions in the year following the intervention in the intervention group versus the control group. There were no statistically significant differences in the number of admissions, the MAI scores, or the number of medications meeting Beers Criteria between the two groups. Although this study did not demonstrate a decrease in hospital admissions, it shows that pharmacist review of medications at discharge can identify potentially unnecessary medications that could lead to confusion or adverse events. Further research is necessary to identify interventions to prevent readmissions in this high-risk population.

The effect of hospitalization on potentially inappropriate medication use in older adults with chronic kidney disease

Objectives: Potentially inappropriate medication (PIM) use is associated with increased morbidity and mortality in chronic kidney disease (CKD). However, there is a paucity of data on how hospitalization affects PIM use in older adults with CKD. Therefore, we aimed to measure the impact of hospitalization on PIM use in older CKD patients, and identify factors predicting PIM use.Methods: A retrospective cohort study was conducted in older adults (≥65 years) with CKD admitted to an Australian tertiary care hospital over a 6 month period. PIM use was measured, upon admission and at discharge, using the Medication Appropriateness Index (MAI) and Beers criteria (2015 version) for medications recommended to be avoided in older adults and under certain conditions.Results: The median age of the 204 patients was 83 years (interquartile range (IQR): 76–87 years) and most were men (61%). Overall, the level of PIM use (MAI) decreased from admission to discharge (median [IQR]: 6 [3–12] to 5 [2–9]; p < .01]). More than half of the participants (55%) had at least one PIM per Beers criterion on admission, which was reduced by discharge (48%; p < .01). People admitted with a higher number of medications (β 0.72, 95% CI 0.56–0.88) and lower eGFR values (β − 0.11, 95% CI −0.18 to −0.04) had higher MAI scores after adjusting for age, sex and Charlson’s comorbidity index.Conclusions: PIMs were commonly used in older CKD patients. Hospitalization was associated with a reduction in PIM use, but there was considerable scope for improvement in these susceptible individuals.

Influence of pharmacist intervention on drug safety of geriatric inpatients: a prospective, controlled trial.

Background:Demographic shift leads to an increasing number of geriatric patients suffering from multimorbidity and resulting polypharmacy. Polypharmacy is shown to be associated with drug-related problems (DRPs) and increased morbidity. For Germany, a hospital-based intervention may be successful optimizing of polypharmacy. The aim of this study was to reduce DRPs in geriatric inpatients by a structured pharmacist’s intervention and to measure the acceptance rate of pharmaceutical recommendations.Methods:This study followed an open, prospective, quasi-randomized, controlled design and was conducted in a geriatric department in a teaching hospital in Germany. Patients of all sexes were included, with a minimum age of 70 years, a written informed consent and a regular intake of at least five drugs daily. Primary outcome was the percentage of patients having a DRP at admission and discharge. A DRP was defined as a prescription without indication or a relevant drug–drug interaction or prescription of a potentially inappropriate medication or presence of an adverse drug reaction. Recommendations were classified and discussed face to face. Statistical analyses were performed using a full-set analysis and a matched-pairs design.Results:Within 12 months, 411 patients were recruited with median age of 82 years (intervention: n = 209; control: n = 202). Median number of drugs at admission was 10 (range 5–24), at discharge 9 (range 3–21). In the intervention group, the percentage of patients with a DRP was reduced from 86.6% to 56.0%; in the control group, from 76.7% to 76.2% (p value < 0.001). Medication appropriateness index score was reduced by 56% in the intervention group and by 0.2% in the control group (p value < 0.001). Implementation rate of the pharmaceutical recommendation was 80%.Conclusion:This prospective controlled trial showed that a pharmacist’s intervention was successful in optimizing polypharmacy in geriatric inpatients.

Effects of a multifaceted intervention in psychogeriatric patients: one-year prospective study.

The aetiology of behavioural and psychological symptoms (BPSD) could be related to inadequate treatment in patients with dementia. The aim of this study was to determine how a multifaceted intervention based on a medication review and multidisciplinary follow-up could improve treatment and minimise risk in these patients. A prospective interventional study was undertaken between July 2015 and July 2016 of patients with dementia admitted to control BPSD. Patients with previous psychiatric illness or palliative care were excluded. Prescription information was obtained from Aegerus and the Catalonia clinical record HC3. The intervention was conducted by a multidisciplinary team. The Medication Appropriateness Index (MAI) was used to assess the intervention. 65 patients (60% women, mean age 84.9±6.7 years) with mild-moderate cognitive impairment (mean 4.5±1.8), moderate-severe functional dependence (mean 43.8±23.9) and a high prevalence of geriatric syndromes and comorbidity were included in the study. 87.7% of the patients were taking ≥5 drugs (mean 9.0±3.1) and 38.5% were taking ≥10. Patients presented with BPSD values of 1.9±0.8 at admission. Common symptoms prompting admission were agitation (47.7%) and irritability (43.1%). A total of 175 drug-related problems (DRPs) were detected (2.97 per patient). Significant differences (p<0.001) were found between the MAI score at admission (4±4.6) and post-intervention (0.5±2.6). Most prevalent MAI criteria were related to interactions (40%), dosage (38.5%) and duplication (26.2%). 55 patients (84.6%) were taking anticholinergic drugs at admission (2.6±1.2 anticholinergic drugs per patient), and the post-intervention reduction was significant (p<0.016). The balance between effective treatment and safety is complex in these patients. Medication review in interdisciplinary teams is an essential component to optimise interventions and assessment of safety.
