Optimizing anticoagulation therapy for in-hospital patients on direct oral anticoagulants: a single-centre modified Delphi study.

AIMS: The management of patients treated with direct oral anticoagulants (DOACs) during hospitalization is a common challenge in clinical practice. Although bridging is generally not recommended, too often DOACs are switched to parenteral therapy with low molecular weight heparins. Our objectives were to update a local guideline for perioperative DOAC management and to develop a guideline for the anticoagulation management in non-surgical patients regarding temporary DOAC discontinuation. METHODS: We executed a two-step modified Delphi study in a 1000-bed university hospital in Belgium. The Delphi questionnaires were developed based on a literature review and a telephone survey of prescribers. Two expert panels were established: one dedicated to perioperative DOAC management and the other to DOAC management in non-surgical patients. Both panels completed two rounds, commencing with an individual and online round, followed by a face-to-face group session. RESULTS: After the two-round Delphi process, the updated perioperative guideline on DOAC management included reasons for delaying the resumption of DOACs following surgery, such as oral intake not possible, the probability of re-intervention within 3 days, and insufficient haemostasis (e.g. active clinically significant haematoma, haemorrhagic drains or wounds). Furthermore, a guideline for non-surgical hospitalized patients was developed, outlining possible reasons for interrupting DOAC therapy. Both guidelines offer clear anticoagulation therapy strategies corresponding to the identified scenarios. CONCLUSIONS: We have updated and developed guidelines for DOAC management in surgical and non-surgical patients during hospitalization, which aim to support prescribers and to enhance targeted prescription review by hospital pharmacists.

Pharmacodynamic Drug-Drug Interactions and Bleeding Outcomes in Patients with Atrial Fibrillation Using Non-Vitamin K Antagonist Oral Anticoagulants: a Nationwide Cohort Study.

PURPOSE: Pharmacodynamic drug-drug interactions (PD DDIs) may influence the safety of non-vitamin K antagonist oral anticoagulants (NOACs), but the extent to which PD DDIs increase bleeding risks, remains unclear. Therefore, the impact of PD DDIs on bleeding outcomes in NOAC-treated patients with atrial fibrillation (AF) was investigated. METHODS: Using Belgian nationwide data, NOAC-treated AF patients were included between 2013-2019. Concomitant use of PD interacting drugs when initiating NOAC treatment was identified. RESULTS: Among 193,072 patients, PD DDIs were identified in 114,122 (59.1%) subjects. After multivariable adjustment, concomitant use of PD interacting drugs was associated with significantly higher risks of major or clinically-relevant non-major bleeding (adjusted hazard ratio (aHR) 1.19, 95% confidence interval (CI) (1.13-1.24)), gastrointestinal (aHR 1.12, 95%CI (1.03-1.22)), urogenital (aHR 1.21, 95%CI (1.09-1.35)) and other bleeding (aHR 1.28, 95%CI (1.20-1.36)), compared to NOAC-treated AF patients without PD interacting drug use. Increased bleeding risks were most pronounced with P2Y12 inhibitors (aHR 1.62, 95%CI (1.48-1.77)) and corticosteroids (aHR 1.53, 95%CI (1.42-1.66)), followed by selective serotonin or serotonin and norepinephrine reuptake inhibitors (SSRI/SNRI, aHR 1.26, 95%CI (1.17-1.35)), low-dose aspirin (aHR 1.14, 95%CI (1.08-1.20)) and non-steroidal anti-inflammatory drugs (NSAID, aHR 1.10, 95%CI (1.01-1.21)). Significantly higher intracranial bleeding risks in NOAC users were observed with SSRI/SNRIs (aHR 1.50, 95%CI (1.25-1.81)) and corticosteroids (aHR 1.49, 95%CI (1.21-1.84)). CONCLUSION: Concomitant use of PD interacting drugs, especially P2Y12 inhibitors and corticosteroids, was associated with higher major, gastrointestinal, urogenital, and other bleeding risks in NOAC-treated AF patients. Remarkably, higher intracranial bleeding risks were observed with SSRI/SNRIs and corticosteroids.

Community pharmacists' evaluation of potentially inappropriate prescribing in older community-dwelling patients with polypharmacy: observational research based on the GheOP³S tool.

Background: In this study, we aimed to (i) determine the prevalence of potentially inappropriate prescribing (PIP) in community-dwelling older polypharmacy patients using the Ghent Older People's Prescriptions community-Pharmacy Screening (GheOP³S) tool, (ii) identify the items that account for the highest proportion of PIP and (iii) identify the patient variables that may influence the occurrence of PIP. Additionally, pharmacist-physician contacts emerging from PIP screening with the GheOP³S tool and feasibility of the GheOP³S tool in daily practice were evaluated. Methods: A prospective observational study was carried out between December 2013 and July 2014 in 204 community pharmacies in Belgium. Patients were eligible if they were (i) ≥70 years, (ii) community-dwelling, (iii) using ≥5 chronic drugs, (iv) a regular visitor of the pharmacy and (v) understanding Dutch or French. Community pharmacists used a structured interview to obtain demographic data and medication use and subsequently screened for PIP using the GheOP³S tool. A Poisson regression was used to investigate the association between different covariates and the number of PIP. Results: In 987 (97%) of 1016 included patients, 3721 PIP items were detected (median of 3 per patient; inter quartile range: 2-5). Most frequently involved with PIP are drugs for the central nervous system such as hypnosedatives, antipsychotics and antidepressants. Risk factors for a higher PIP prevalence appeared to be a higher number of drugs (30% extra PIPs per 5 extra drugs), female gender (20% extra PIPs), higher body mass index (BMI, 20% extra PIPs per 10-unit increase in BMI) and poorer functional status (30% extra PIPs with 6-point increase). The feasibility of the GheOP³S tool was acceptable although digitalization of the tool would improve implementation. Despite detecting at least one PIP in 987 patients, only 39 physicians were contacted by the community pharmacists to discuss the items. Conclusion: A high prevalence of PIP in community-dwelling older polypharmacy patients in Belgium was detected which urges for interventions to reduce PIP.

Older patients' prescriptions screening in the community pharmacy: development of the Ghent Older People's Prescriptions community Pharmacy Screening (GheOP³S) tool.

BACKGROUND: Ageing of the population often leads to polypharmacy. Consequently, potentially inappropriate prescribing (PIP) becomes more frequent. Systematic screening for PIP in older patients in primary care could yield a large improvement in health outcomes, possibly an important task for community pharmacists. In this article, we develop an explicit screening tool to detect relevant PIP that can be used in the typical community pharmacy practice, adapted to the European market. METHODS: Eleven panellists participated in a two-round RAND/UCLA (Research and Development/University of California, Los Angeles) process, including a round zero meeting, a literature review, a first written evaluation round, a second face-to-face evaluation round and, finally, a selection of those items that are applicable in the contemporary community pharmacy. RESULTS: Eighteen published lists of PIP for older patients were retrieved from the literature, mentioning 398 different items. After the two-round RAND/UCLA process, 99 clinically relevant items were considered suitable to screen for in a community pharmacy practice. A panel of seven community pharmacists selected 83 items, feasible in the contemporary community pharmacy practice, defining the final GheOP³S tool. CONCLUSION: A novel explicit screening tool (GheOP³S) was developed to be used for PIP screening in the typical community pharmacy practice.

Potentially inappropriate prescribing in community-dwelling older people across Europe: a systematic literature review.

BACKGROUND: Potentially inappropriate prescribing (PIP) is one of the main risk factors for adverse drug events (ADEs) in older people. PURPOSE: This systematic literature review aims to determine prevalence and type of PIP in community-dwelling older people across Europe, as well as identifying risk factors for PIP. METHODS: The PubMed and Web of Science database were searched systematically for relevant manuscripts (January 1, 2000-December 31, 2014). Manuscripts were included if the study design was observational, the study participants were community-dwelling older patients in Europe, and if a published screening method for PIP was used. Studies that focused on specific pathologies or that focused on merely one inappropriate prescribing issue were excluded. Data analysis was performed using R statistics. RESULTS: Fifty-two manuscripts were included, describing 82 different sample screenings with an estimated overall PIP prevalence of 22.6 % (CI 19.2-26.7 %; range 0.0-98.0 %). Ten of the sample screenings were based on the Beers 1997 criteria, 19 on the Beers 2003 criteria, 14 on STOPP criteria (2008 version), 8 on START-criteria (2008 version), and 7 on the PRISCUS list. The 24 remaining sample screenings were carried out using compilations of screening methods or used country-specific lists such as the Laroche criteria. It appears that only PIP prevalence calculated from insurance data significantly differs from the other data collection method categories. Furthermore, risk factors most often positively associated with PIP prevalence were polypharmacy, poor functional status, and depression. Drug groups most often involved in PIP were anxiolytics (ATC-code: N05B), antidepressants (N06A), and nonsteroidal anti-inflammatory and anti-rheumatic products (M01A). CONCLUSION: PIP prevalence in European community-dwelling older adults is high and depends partially on the data collection method used. Polypharmacy, poor functional status, and depression were identified as the most common risk factors for PIP.

The Productive Ward program™: a longitudinal multilevel study of nurse perceived practice environment, burnout, and nurse-reported quality of care and job outcomes.

OBJECTIVE: The objective of this study was to investigate the impact of The Productive Ward-Releasing Time to Care™ program implemented in a hospital transformation process on nurse perception related to practice environment, burnout, quality of care, and job outcomes. BACKGROUND: To address the continuously evolving complex challenges of patient care, high-performance nursing care is necessary. METHODS: A longitudinal survey design was used to conduct a study in a 600-bed acute care university hospital with 3 measurement periods: T0: base line in 2006, T1 in 2011, and T2 in 2013. As part of the hospital transformation process, the productive ward program was introduced between T1 and T2. RESULTS: Relevant impact on nurse-physician relations, nurse management, hospital management-organizational support, nurse-reported quality of care, and job outcomes were identified. CONCLUSION: Hospital strategies and policies should be aligned with daily practices so that engaged and committed staff can promote excellent outcomes.

Impact of model-informed precision dosing in adults receiving vancomycin via continuous infusion: a randomized, controlled clinical trial.

BACKGROUND: Vancomycin is a commonly prescribed antibiotic to treat gram-positive infections. The efficacy of vancomycin is known to be directly related to the pharmacokinetic/pharmacodynamic (PK/PD) index of the area under the concentration-time curve (AUC) divided by the minimal inhibitory concentration (MIC) of the pathogen. However, in most countries, steady-state plasma concentrations are used as a surrogate parameter of target AUC/MIC, but this practice has some drawbacks. Hence, direct AUC-guided monitoring of vancomycin using model-informed precision dosing (MIPD) tools has been proposed for earlier attainment of target concentrations and reducing vancomycin-related nephrotoxicity. However, solid scientific evidence for these benefits in clinical practice is still lacking. This randomized controlled trial (RCT) aims to investigate the clinical utility of MIPD dosing of vancomycin administered via continuous infusion in hospitalized adults. METHODS: Participants from 11 wards at two Belgian hospitals are randomly allocated to the intervention group or the standard-of-care comparator group. In the intervention group, clinical pharmacists perform dose calculations using CE-labeled MIPD software and target an AUC24h of 400 to 600 mg × h/L, whereas patients in the comparator group receive standard-of-care dosing and monitoring according to the institutional guidelines. The primary endpoint is the proportion of patients reaching the target AUC24h/MIC of 400-600 between 48 and 72 h after start of vancomycin treatment. Secondary endpoints are the proportion of patients with (worsening) acute kidney injury (AKI) during and until 48 h after stop of vancomycin treatment, the proportion of patients reaching target AUC24h/MIC of 400-600 between 72 and 96 h after start of vancomycin treatment, and the proportion of time within the target AUC24h/MIC of 400-600. DISCUSSION: This trial will clarify the propagated benefits and provide new insights into how to optimally monitor vancomycin treatment. TRIAL REGISTRATION: EudraCT number: 2021-003670-31. Registered June 28, 2021. CLINICALTRIALS: gov identifier: NCT05535075. Registered September 10, 2022. Protocol version 3, protocol date: April 21, 2023.

Strategies to reduce the risk of iatrogenic illness in complex older adults.

Older patients are particularly vulnerable to adverse drug reactions (ADRs) because age is associated with changes in pharmacokinetics and pharmacodynamics that may alter drug metabolism. In addition, other conditions, commonly observed in older adults, may increase the risk of ADRs in the older population (including polypharmacy, comorbidity, cognitive and functional limitations). ADRs in older adults are frequently preventable, suggesting that screening and prevention programmes aimed at reducing the rate of iatrogenic illness are necessary in this population. The present study reviews available approaches that may be used to screen and prevent the occurrence of ADRs in older adults, including medication review, avoiding the use of potentially inappropriate medications, computer-based prescribing systems and comprehensive geriatric assessment. Available evidence on these approaches is mixed and controversial, and none of them showed a clear beneficial effect on patients' health outcomes. Limitation of these interventions is the lack of standardisation, and these differences may give reason for the variability of the results documented in randomised clinical studies. Interestingly, most of the available research is focused on a single intervention targeting either clinical or pharmacological factors causing ADRs. When these approaches are combined, positive effects on patients health outcomes can be shown, suggesting that integration of skills from different health care professionals is needed to address medical complexity of the older adults. The challenge for future research is to integrate valuable information obtained by existing instruments and methodologies in a complete and global approach targeting all potential factors involved in the onset of ADRs.

Therapeutic dilemmas with benzodiazepines and Z-drugs: insomnia and anxiety disorders versus increased fall risk: a clinical review.

PURPOSE: The aim of this clinical review was to summarise the existing knowledge on fall risk associated with benzodiazepines (BZDs) and Z-drugs in older people with focus on appropriate prescribing, including deprescribing. METHODS: We conducted a literature search in June 2021 in PubMed and Embase with citation and reference checking. Personal reference libraries and international websites were also used. Keywords for the searches included "benzodiazepines", "Z-drugs", "falls", "deprescribing", "fall-risk-increasing-drugs", "inappropriate prescribing", "older people" and matching synonyms. We discuss use of BZDs and Z-drugs, potential fall-related adverse reactions, alternatives for and deprescribing of BZDs and Z-drugs in older persons. RESULTS: BZDs and Z-drugs differ in fall-related adverse effect profile. They contribute to fall risk through orthostatic hypotension, dizziness and/or imbalance, sedation, muscular weakness, ataxia, etc. Fall incidents contribute significantly to mortality and morbidity. Therefore, there is a need for appropriate prescribing and use of BZDs and Z-drugs in older people. In practice, this means pertaining to a strict indication, strongly consider to non-pharmacological alternatives, limit use to the lowest dose and the shortest duration possible. Judicious deprescribing should be considered and encouraged as well. Practical resources, tools and algorithms are available to guide and assist clinicians in deprescribing BZDs and Z-drugs. CONCLUSIONS: Prescribing BZDs and Z-drugs should be done in a well-considered way in fall-prone older people. A good overview and insight in the fall-related adverse effects of these drugs, as well as the availability of different strategies to increase the appropriate use, including deprescribing initiatives, can assist clinicians in clinical decision-making.

Model-informed precision dosing of vancomycin via continuous infusion: a clinical fit-for-purpose evaluation of published PK models.

BACKGROUND: Model-informed precision dosing is an innovative approach used to guide bedside vancomycin dosing. The use of Bayesian software requires suitable and externally validated population pharmacokinetic (popPK) models. OBJECTIVES: This study aimed to identify suitable popPK models for a priori prediction and a posteriori forecasting of vancomycin in continuous infusion. Additionally, model averaging (MAA) and model selection approach (MSA) were compared with the identified popPK models. METHODS: Clinical pharmacokinetic data were retrospectively collected from patients receiving continuous vancomycin therapy and admitted to a general ward of three large Belgian hospitals. The predictive performance of the popPK models, identified in a systematic literature search, as well as the MAA/MSA were evaluated for the a priori and a posteriori scenarios using bias, root mean square errors, normalised prediction distribution errors and visual predictive checks. RESULTS: The predictive performance of 23 popPK models was evaluated based on clinical data from 169 patients and 923 therapeutic drug monitoring samples. Overall, the best predictive performance was found using the Okada et al. model (bias < -0.1 mg/L) followed by the Colin et al. MODEL: The MAA/MSA predicted with a constantly high precision and low inaccuracy and were clinically acceptable in the Bayesian forecasting. CONCLUSION: This study identified the two-compartmental models of Okada et al. and Colin et al. as most suitable for non-ICU patients to forecast individual exposure profiles after continuous vancomycin infusion. The MAA/MSA performed equally as well as the individual popPK models; therefore, both approaches could be used in clinical practice to guide dosing decisions.

Variation in vancomycin dosing and therapeutic drug monitoring practices in neonatal intensive care units.

Background Vancomycin is a frequently used antibiotic in neonates. However, there is no consensus guideline on the optimal dosing regimen and therapeutic drug monitoring (TDM) practices in this patient population. Objective To document the variability in the current dosing and TDM practices in neonatal intensive care units (NICU). Setting Belgian and Dutch NICUs. Method An online questionnaire was disseminated by e-mail to potential respondents. Main outcome measure Differences in vancomycin dosing and TDM practices in comparison with a reference source, the Dutch Paediatric Formulary. Results Eighteen NICUs (response rate 62%) participated. Eleven different dosing regimens are applied, with 83% using intermittent dosing regimens. Stratifying covariates used to determine the (initial) dosage include gestational age, postnatal age, serum creatinine, concurrent use of non-steroidal anti-inflammatory drugs, birth weight and current weight. Large variability is observed with regard to TDM practice as well, both for the concentration target range and the times of (re)sampling. Dosing calculators are more commonly used in the Netherlands than Belgium. Conclusion Significant inter-centre variability in dosing and TDM practices was found. The development of international consensus guidelines is required to optimize therapy. Dosing calculators to guide dosing are not yet considered as part of standard-of-care.

The use of hypnosedative drugs in a university hospital: has anything changed in 10 years?

AIM: Our goal was to investigate the use of hypnosedatives (HSs) before and during hospitalization, explore the relationship between their use and various demographic and clinical variables, and compare the results with data from a similar 2000 study with particular interest in adherence to hospital formulary guidelines. METHODS: A cross-sectional observational survey of 326 hospitalized patients recruited from ten wards of the Ghent University Hospital, Gent, Belgium, with a patient interview and by evaluating medical and nursing files. RESULTS: In 30.7% of patients, the use of a HS before admission was reported. According to the patient interview, 33.1% used a HS during hospitalization. However, according to medical and nursing files, use of HSs in the hospital was 10% higher (43.3%). In 19.4% of patients who took HSs before admission, their use was discontinued in the hospital. In 15.6% of patients who took no HS before admission, a HS was started in the hospital, according to the formulary guidelines (data from files). There was a positive correlation between HS use in the hospital and older age, longer hospitalization, not coming from home, higher number of HSs taken before hospitalization, sleeping problems emerging during hospitalization, and central nervous system (CNS) disorders. In comparison with 2000, we registered a slight decrease in HS use during hospitalization and a decrease in the number of newly started patients. CONCLUSIONS: The prevalence of HS use in our university hospital is high, mostly as a result of continuation of HSs started before admission, as there seems to be no general policy of active cessation. Compared with the survey performed 10 years ago, fewer hospitalized patients are newly started on HSs, and when this is the case, the formulary guidelines are followed.

Guidance for appropriate use of psychotropic drugs in older people.

Psychotropic drugs are widely prescribed in older people although their use is associated with important risks. In this position paper, we discuss the appropriateness of using these medications in older people in terms of different aspects such as indications, contraindications, dosing, adverse drug reactions, interactions and duration of therapy. Consequently, we discuss different strategies to increase the appropriateness of therapy while formulating some practical recommendations to keep in mind when (de)prescribing psychotropic drugs in older people.

Ghent Older People's Prescriptions Community Pharmacy Screening (GheOP3S)-Tool Version 2: Update of a Tool to Detect Drug-Related Problems in Older People in Primary Care.

BACKGROUND: The Ghent Older People's Prescriptions community Pharmacy Screening (GheOP3S)-tool was developed in 2016 as a screening tool to detect drug-related problems (DRPs) and to help in performing medication reviews in older people (≥ 65 years). OBJECTIVE: This study aimed to revise and update the GheOP3S-tool. METHODS: Users' comments were collected to improve the usability and appropriateness of the original GheOP3S-tool, followed by a two-round modified Delphi process according to the RAND/UCLA appropriateness method. This included a literature review, a round zero meeting, a first written round (with 15 international and multidisciplinary experts) and a second face-to-face round (with 11 experts) to change, delete or add GheOP3S-criteria. An additional third round with 14 community pharmacists was organised to preserve criteria applicable in the current community pharmacy practice. RESULTS: The updated GheOP3S-tool consists of five lists of DRPs and a new addendum containing medications that should be avoided or used with caution in older people with reduced renal function. During the first two rounds, related criteria were grouped, 14 criteria were added and 17 criteria were deleted from the original tool. All criteria were deemed applicable in round 3. This led to a final tool (version 2) with 64 GheOP3S-criteria. CONCLUSION: GheOP3S-criteria were revised and updated according to experts' agreement on their clinical relevance and recent scientific evidence. Future studies should investigate the impact of pharmacist-led medication reviews with GheOP3S-tool version 2 on clinical, humanistic and economic outcomes in primary care.

Vancomycin dosing and therapeutic drug monitoring practices: guidelines versus real-life.

Background Correct dosing and therapeutic drug monitoring (TDM) practices are essential when aiming for optimal vancomycin treatment. Objective To assess target attainment after initial dosing and dose adjustments, and to determine compliance to dosing and TDM guidelines. Setting Tertiary care university hospital in Belgium. Method A chart review was performed in 150 patients, ranging from preterm infants to adults, treated intravenously with vancomycin. Patient characteristics, dosing and TDM data were compared to evidence-based hospital guidelines. Main outcome measures Target attainment of vancomycin after initial dosing and dose adjustments. Results Subtherapeutic concentrations were measured in 68% of adults, in 76% of children and in 52% of neonates after treatment initiation. Multiple dose adaptations (median 2, Q1 1-Q3 2) were required for target attainment, whilst more than 20% of children and neonates never reached targeted concentrations. Regarding compliance to the hospital guideline, some points of improvement were identified: omitted dose adjustment in adults with decreased renal function (53%), delayed sampling (16% in adults, 31% in children) and redundant sampling (34% of all samples in adults, 12% in children, 13% in neonates). Conclusion Target attainment for vancomycin with current dosing regimens and TDM is poor in all age groups. Besides, human factors should not be ignored when aiming for optimal treatment. This study reflects an ongoing challenge in clinical practice and highlights the need for optimization of vancomycin dosing strategies and improvement of awareness of all health care professionals involved.

Application of the GheOP3S-tool in nursing home residents: acceptance and implementation of pharmacist recommendations.

Background and objective: The prevalence of potentially inappropriate prescribing (PIP) among nursing home (NH) residents is high. This study aimed to investigate the acceptance and implementation of pharmacist recommendations based on a screening tool for PIP, the Ghent Older People's Prescriptions community Pharmacy Screening (GheOP3S)-tool. Setting and method: Prospective observational study in NH residents (≥ 70 years, using ≥ 5 medications) with a 3-month follow-up period. A pharmacist screened the medication lists using the GheOP3S-tool and formulated recommendations to reduce PIP. The acceptance of recommendations discussed during face-to-face pharmacist-general practitioner (GP) meetings was recorded. Implementation was examined by comparing baseline and follow-up medication lists. A pre-post comparison of the number of chronic medications and GheOP3S-criteria; the anticholinergic and sedative burden quantified by the Drug Burden Index (DBI); and medication costs was performed. Results: Screening with the GheOP3S-tool resulted in 168 pharmacist recommendations for 50 NH residents, mainly to stop (78.0%) and to substitute (14.3%) medications. Ninety-three % (156/168) of recommendations were considered relevant. GPs acceptance rate was 44.9%. Fifty-four % of all accepted recommendations were implemented. At follow-up, the number of chronic medications (p = 0.007), and DBI scores (p = 0.004) significantly differed from baseline. There was no significant decrease in the number of GheOP3S-criteria (p = 0.075) and medication costs (p > 0.05). Conclusion: The acceptance and implementation of pharmacist recommendations were relatively low. Future studies should increase the involvement of patients and all health-care providers. Interdisciplinary collaboration with sufficient education for all disciplines and patients is essential.

Medication Counselling in Older Patients Prior to Hospital Discharge: A Systematic Review.

BACKGROUND: Older patients are regularly exposed to multiple medication changes during a hospital stay and are more likely to experience problems understanding these changes. Medication counselling is often proposed as an important component of seamless care to ensure appropriate medication use after hospital discharge. OBJECTIVES: The purpose of this systematic review was to describe the components of medication counselling in older patients (aged ≥ 65 years) prior to hospital discharge and to review the effectiveness of such counselling on reported clinical outcomes. METHODS: Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology (PROSPERO CRD42019116036), a systematic search of MEDLINE, EMBASE and CINAHL was conducted. The QualSyst Assessment Tool was used to assess bias. The impact of medication counselling on different outcomes was described and stratified by intervention content. RESULTS: Twenty-nine studies were included. Fifteen different components of medication counselling were identified. Discussing the dose and dosage of patients' medications (19/29; 65.5%), providing a paper-based medication list (19/29; 65.5%) and explaining the indications of the prescribed medications (17/29; 58.6%) were the most frequently encountered components during the counselling session. Twelve different clinical outcomes were investigated in the 29 studies. A positive effect of medication counselling on medication adherence and medication knowledge was found more frequently, compared to its impact on hard outcomes such as hospital readmissions and mortality. Yet, evidence remains inconclusive regarding clinical benefit, owing to study design heterogeneity and different intervention components. Statistically significant results were more frequently observed when counselling was provided as part of a comprehensive intervention before discharge. CONCLUSIONS: Substantial heterogeneity between the included studies was found for the components of medication counselling and the reported outcomes. Study findings suggest that medication counselling should be part of multifaceted interventions, but the evidence concerning clinical outcomes remains inconclusive.

A shared medication scheme for community dwelling older patients with polypharmacy receiving home health care: role of the community pharmacist.

Background and objective: An accurate medication scheme may be a useful tool to improve medication safety in primary care. This study aimed to identify (1) pharmacists' alterations to nurse medication schemes and (2) potential improvements to the contribution of the community pharmacist to a shared medication scheme within a multidisciplinary collaboration. Dosing frequency, potentially incorrect moments of intake, drug-drug interactions and medication complexity (quantified by the Medication Regimen Complexity Index, MRCI) were investigated. Setting and method: Observational study in community dwelling older patients (≥70 years) with polypharmacy receiving home health care (i.e. medications being prepared and/or administered by home care nurses). Home care nurses provided the community pharmacist with the original medication scheme ('nurse medication scheme'), subsequently the community pharmacist generated a standardized 'pharmacist medication scheme' which was uploaded on an electronic health platform (Vitalink). The researcher recorded all pharmacists' alterations and looked for possible additional improvements ('researcher medication scheme'). Results: Pharmacists made 482 alterations to the nurse medication schemes of 31 patients. Most important alterations included adding indication (61%), generic or brand name (18%) and moment of intake (9%). Pharmacists did not reduce dosing frequency. MRCI scores (median [IQR]) significantly differed between pharmacist (38 [15]) and nurse medication schemes (32 [11]) (p < 0.001) and between nurse (32 [11]) and researcher medication schemes (40 [15]) (p < 0.001). Conclusion: Alterations made by the community pharmacists enable more complete and accurate medication schemes; however, there is room for improvement in optimizing the patient's medication scheme in a multidisciplinary collaboration.

The Introduction of a Full Medication Review Process in a Local Hospital: Successes and Barriers of a Pilot Project in the Geriatric Ward.

For the majority of Belgian hospitals, a pharmacist-led full medication review process is not standard care and, therefore, challenging to introduce. With this study, we aimed to evaluate the successes and barriers of the implementation of a pharmacist-led full medication review process in the geriatric ward at a local Belgian hospital. To this end, we carried out an interventional study, performing a full medication review on older patients (≥70 years) with polypharmacy (≥5 drugs) who had an unplanned admission to the geriatric ward. The process consisted of 3 steps: (1) medication reconciliation upon admission; (2) medication review using an explicit reviewing tool (STOPP/START criteria or GheOP³S tool), followed by a discussion between the pharmacist and the geriatrician; and (3) medication reconciliation upon discharge. Ethical approval was obtained from the Ethical Commission of the Ghent University Hospital. Outcomes included objective data on the interventions (e.g., number of drug discrepancies; number of potentially inappropriate prescriptions (PIP)); as well as subjective experiences (e.g., satisfaction with service; opinion on inter-professional communication). There was a special focus on communication aspects within the introduction of this process. In total, 52 patients were included in the study, taking a median of 10 drugs (IQR 8-12). Upon admission, 122 drug discrepancies were detected. During medication review, 254 PIPs were detected and discussed, leading to an improvement in the appropriateness of medication use. The satisfaction of community pharmacists concerning additional communication and the satisfaction of the patients after counselling at discharge were positive. However, several barriers were encountered, such as the time-consuming process to gather necessary information from different sources, the non-continuity of the service due to the lack of trained personnel or the lack of safe, electronic platforms to share information. The communicative and non-communicative successes and hurdles encountered during this project need to be addressed in order to improve the full medication review process and to strengthen the role of the clinical pharmacist.

Development and Application of the GheOP3S-Tool Addendum on Potentially Inappropriate Prescribing (PIP) of Renally Excreted Active Drugs (READs) in Older Adults with Polypharmacy.

BACKGROUND: Renal function progressively worsens with age. Potentially inappropriate prescribing (PIP) of renally excreted active drugs (READs) is common in older adults, leading to an increased rate of iatrogenic illness. The Ghent Older People's Prescription community Pharmacy Screening (GheOP3S-) tool is an effective, explicit instrument that was developed for community pharmacists (CPs) to detect PIP. So far, this tool does not assess PIP of the frequently used READs in older patients with renal impairment. OBJECTIVES: This study aimed to expand the GheOP3S-tool with the first addendum to screen for PIP of frequently used READs, and to perform a cross-sectional analysis using the addendum and the medication history of a group of older adults with polypharmacy. METHODS: The addendum was developed in three steps: (1) collection of individual and combined READs, (2) collection of dose-adjustment recommendations, and (3) expert panel evaluation. Consequently, the addendum was applied retrospectively on the medication list of 60 older adults with polypharmacy and with four renal function-estimating equations. RESULTS: The addendum includes 61 READs recommendations for dose/drug-adjustment alternatives, laboratory test follow-ups, and patients' referral to specialists' care. In the cross-sectional analysis, 35-78% of patients were diagnosed with renal impairment, depending on the equations used for renal function estimation. Among patients with renal impairment, 21-46% of the prescribed READs were deemed potentially inappropriate by the GheOP3S-tool addendum. CONCLUSION: The GheOP3S-tool was expanded with an addendum on PIP of READs in renal impairment for older patients. The cross-sectional analysis using the addendum suggests that PIP of READs is common in older patients with polypharmacy and renal impairment. Using this addendum, CPs might contribute to diminishing PIP of READs.
