Prevalence, characteristics and predicting risk factors of adverse drug reactions among hospitalized older adults: A systematic review and meta-analysis. SAGE Open Med 2021; 9:20503121211039099. [PMID: 34422271 PMCID: PMC8377309 DOI: 10.1177/20503121211039099] [Citation(s) in RCA: 23] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2021] [Accepted: 07/23/2021] [Indexed: 11/22/2022] Open
Abstract
BACKGROUND Occurrence of adverse drug reactions is a major global health problem mostly affecting older adults. Identifying the magnitude and predictors of adverse drug reactions is crucial to developing strategies to mitigate the burden of adverse drug reactions. This study's objectives were to estimate and compare the prevalences of adverse drug reactions, to characterize them and to identify the predictors among hospitalized older adults. METHODS A comprehensive systematic literature search including both prevalence and risk factors of adverse drug reactions in hospitalized older adults was conducted using PubMed, Scopus and Google Scholar, involving all articles published in English. Descriptive statistics and comparison of means was performed using SPSS version 20.0 and metaprop command was performed in STATA version 13.0. Heterogeneity was assessed using I 2 statistic. RESULTS A total of 18 studies, involving 80,695 participants with a median age of 77 years, were included in this study. The pooled prevalence of adverse drug reaction was 22% (95% confidence interval: 17%, 28%; I 2 = 99.23%). Among high-income countries, the prevalence of adverse drug reactions was 29% (95% confidence interval: 16%, 42%) as compared to 19% (95% confidence interval: 14%-25%) in low and middle-income countries (p value = 0.176). Of the 620 adverse drug reactions categorized, most were type A (89%), which are generally predictable and preventable. Two-thirds (795, 67%) of the adverse drug reactions were probable and most (1194, 69%) were mild or moderate. The majority (60%) of the categorized adverse drug reactions were preventable and less than one-third (31%) were severe. The most consistently reported predictors of adverse drug reactions in hospitalized older patients were medication-related factors, including polypharmacy and potentially inappropriate medications followed by disease-related factors-renal failure, complex comorbidity, heart failure and liver failure. CONCLUSION Almost one-quarter of all hospitalized older adults experienced at least one adverse drug reaction during their hospital stay. The majority of the adverse drug reactions were preventable. Medication-related factors were the most consistently reported predictors of adverse drug reactions followed by disease-related factors.

Abstract
Background Medication harm can lead to hospital admission, prolonged hospital stay and poor patient outcomes. Reducing medication harm is a priority for healthcare organisations worldwide. Recent Australian studies demonstrate cardiovascular (CV) medications are a leading cause of harm. However, they appear to receive less recognition as ‘high risk’ medications compared with those classified by the medication safety acronym, ‘APINCH’ (antimicrobials, potassium, insulin, narcotics, chemotherapeutics, heparin). Our aim was to determine the scale and type of medication harm caused by CV medications in healthcare. Methods A narrative review of adult (>16 years) medication harm literature identified from PubMed and CINAHL databases was undertaken. Studies with the primary outcome of measuring the incidence of medication harm were included. Harm caused by CV medications was described and ranked against other medication classes at four key stages of a patient’s healthcare journey. Where specified, the implicated medications and type of harm were investigated. Results A total of 75 studies were identified, including seven systematic reviews and three meta-analyses, with most focussing on harm causing hospital admission. CV medications were responsible for approximately 20% of medication harm; however, this proportion increased to 50% in older populations. CV medications were consistently ranked in the top five medication categories causing harm and were often listed as the leading cause. Conclusion CV medications are a leading cause of medication harm, particularly in older adults, and should be the focus of harm mitigation strategies. A practical approach to generate awareness among health professionals is to incorporate ‘C’ (for CV medications) into the ‘APINCH’ acronym. Plain language summary

Abstract
Background Little is known about the epidemiology of medication errors and medication-related harm following transition from secondary to primary care. This systematic review aims to identify and critically evaluate the available evidence on the prevalence and nature of medication errors and medication-related harm following hospital discharge. Methods Studies published between January 1990 and March 2019 were searched across ten electronic databases and the grey literature. No restrictions were applied with publication language or patient population studied. Studies were included if they contained data concerning the rate of medication errors, unintentional medication discrepancies, or adverse drug events. Two authors independently extracted study data. Results Fifty-four studies were included, most of which were rated as moderate (39/54) or high (7/54) quality. For adult patients, the median rate of medication errors and unintentional medication discrepancies following discharge was 53% [interquartile range 33–60.5] (n = 5 studies) and 50% [interquartile range 39–76] (n = 11), respectively. Five studies reported adverse drug reaction rates with a median of 27% [interquartile range 18–40.5] and seven studies reported adverse drug event rates with a median of 19% [interquartile range 16–24]. For paediatric patients, one study reported a medication error rate of 66.3% and another an adverse drug event rate of 9%. Almost a quarter of studies (13/54, 24%) utilised a follow-up period post-discharge of 1 month (range 2–180 days). Drug classes most commonly implicated with adverse drug events were antibiotics, antidiabetics, analgesics and cardiovascular drugs. Conclusions This is the first systematic review to explore the prevalence and nature of medication errors and adverse drug events following hospital discharge. Targets for future work have been identified.

Abstract
Concomitant treatment with drugs that inhibit drug metabolising enzymes and/or transporters, such as commonly prescribed statins and nonsteroidal anti-inflammatory drugs (NSAIDs), has been associated with prolonged drug exposure and increased risk of adverse drug reactions (ADRs) due to drug-drug interactions. The risk is further increased in patients with chronic diseases/comorbidities who are more susceptible because of their genetic setup or external factors. In that light, we present a case of a 46-year-old woman who had been experiencing acute renal and hepatic injury and myalgia over two years of concomitant treatment with diclofenac, atorvastatin, simvastatin/fenofibrate, and several other drugs, including pantoprazole and furosemide. Our pharmacogenomic findings supported the suspicion that ADRs, most notably the multi-organ toxicity experienced by our patient, may be owed to drug-drug-gene interactions and increased bioavailability of the prescribed drugs due to slower detoxification capacity and decreased hepatic and renal elimination. We also discuss the importance of CYP polymorphisms in the biotransformation of endogenous substrates such as arachidonic acid and their modulating role in pathophysiological processes. Yet even though the risks of ADRs related to the above mentioned drugs are substantially evidenced in literature, pre-emptive pharmacogenetic analysis has not yet found its way into common clinical practice.

Abstract
Through pharmacogenomics testing, identifying genetic variants that influence how individuals respond to medications could potentially decrease the "trial and error" approach to prescribing medications, maximize beneficial effects, and reduce risks of adverse drug events. Yet, pharmacogenomics testing is still subject to an ongoing debate over its clinical validity and utility. The purpose of the current integrative review was to examine and synthesize evidence on the clinical application of pharmacogenomics in medication management among older adults. Gaps were found, such as lack of studies investigating the prospective use of pharmacogenomics testing to improve clinical outcomes and lack of strong evidence on the clinical validity and utility of pharmacogenomics testing in the medication management of older adults. However, the review identified evidence for the potential benefits of pharmacogenomics testing to improve older adults' clinical outcomes that warrant further investigation.

Abstract
No studies to investigate the effect of a deprescribing intervention on the occurrence of potential prescribing omissions (PPOs) among elderly patients with polypharmacy have been conducted. Therefore, the effect of deprescribing on PPOs among elderly patients with polypharmacy was investigated. All 121 consecutive elderly patients who received in-hospital deprescribing interventions were evaluated. The primary outcome was any occurrence of PPOs based on the 2015 STOPP/START criteria. The proportion of patients who had any PPOs significantly increased after the deprescribing interventions (52.9% vs 77.7%, p < 0.001). In the multivariable analysis, older age was the only independent risk factor associated with an increased risk of any PPOs after the deprescribing interventions (OR 1.08, 95% CI 1.01 to 1.16). In-hospital deprescribing interventions for elderly patients with polypharmacy may increase the occurrence of PPOs. Further study is warranted to investigate the effects on clinical outcomes of the increased occurrence of PPOs due to the deprescribing intervention.

Abstract
INTRODUCTION Adverse drug events (ADEs) are a major cause of mortality. OBJECTIVE We examined long-term trends for ADE-related deaths in Japan. METHODS This observational study was conducted using the Japanese Vital Statistics from 1999 to 2016. Data for all ADE-related deaths were extracted using International Classification of Diseases, Tenth Revision codes. We analysed ADE-related deaths by age and sex and calculated crude and age-standardised mortality rates (ASMR) per 100,000 people. We used Joinpoint regression analysis to identify significant changing points in mortality trends and to estimate annual percentage change (APC). RESULTS In total, 16,417 ADE-related deaths were identified. The crude mortality rate for individuals aged ≥ 65 years was higher than that of young individuals. The ASMR per 100,000 people increased from 0.44 in 1999 to 0.64 in 2016. The crude mortality rate increased from 0.44 in 1999 to 1.01 in 2016. The APC of ASMR increased at a rate of 2.8% (95% confidence interval [CI] 1.4-4.2) throughout the study period. In addition, crude mortality increased at a rate of 5.7% (95% CI 4.2-7.3) annually from 1999 to 2016. The ADE-related mortality rate was higher for men than for women during the study period. CONCLUSIONS The number of and trend in ADE-related deaths increased in Japan from 1999 to 2016, particularly in the older population.

Abstract
PURPOSE To lay the fundamentals of drug-related problems (DRPs) in older adults, and to organize them according to a logical process conciliating medical and pharmaceutical approaches, to better identify the causes and consequences of DRPs. MATERIALS AND METHODS A narrative overview. RESULTS The causes of DRPs may be intentional or unintentional. They lie in poor prescription, poor adherence, medication errors (MEs) and substance use disorders (SUD). Poor prescription encompasses sub-optimal or off-label drug choice; this choice is either intentional or unintentional, often within a polypharmacy context and not taking sufficiently into account the patient's clinical condition. Poor adherence is often the consequence of a complicated administration schedule. This review shows that MEs are not the most frequent causes of DRPs. SUD are little studied in older adults and needs to be more investigated because the use of psychoactive substances among older people is frequent. Prescribers, pharmacists, nurses, patients, and caregivers all play a role in different causes of DRPs. The potential deleterious outcomes of DRPs result from adverse drug reactions and therapeutic failures. These can lead to a negative benefit-risk ratio for a given treatment regimen. DISCUSSION/CONCLUSION Interdisciplinary pharmacotherapy programs show significant clinical impacts in preventing or resolving adverse drug events and, suboptimal responses. New technologies also seem to be interesting solutions to prevent MEs. Better communication between healthcare professionals, patients and their caregivers would ensure greater safety and effectiveness of treatments.

Abstract
AIM To explore UK professionals' interpretations of medicines optimization and expansion of nurses' roles. DESIGN This mixed-methods study sought professionals' views on nurses' involvement, competency and engagement in monitoring patients for adverse effects of medicines, monitoring adherence, prescribing and patient education. METHOD An online survey and interviews were undertaken with nurses, doctors and pharmacists in Wales and England, May 2018 to July 2019. RESULTS In all, 220 nurses, 17 doctors and 62 pharmacists responded to the online survey, and 24 professionals were interviewed. Nurses were divided over extending their roles, with 123/220 (55.9%) wishing to extend roles in monitoring patients for possible adverse drug reactions (ADRs), 111/220 (50.5%) in adherence monitoring, 121/220 (55.0%) in prescribing and 122/220 (55.4%) in patient education. The best-qualified nurses were the most willing to increase involvement in monitoring patients for ADRs (aOR 13.00, 1.56-108.01). Interviews revealed that both nurses and doctors assumed the other profession was undertaking this monitoring. Respondents agreed that increasing nurses' involvement in medicines optimization would improve patient care, but expressed reservations about nurses' competencies. Collaboration between nurses and doctors was suboptimal (rated 7/10 at best) and between nurses and pharmacists even more so (6/10 at best). CONCLUSION Juxtaposition of datasets identified problems with medicines optimization: although most respondents agreed that increasing nurses' involvement would positively impact practice, their educational preparation was a barrier. Only ~50% of nurses were willing to expand their roles to fill the hiatus in care identified and ensure that at least one profession was taking responsibility for ADR monitoring. IMPACT To improve multiprofessional team working and promote patient safety, nurse leaders should ensure patients are monitored for possible ADRs by at least one profession. Initiatives expanding nurses' roles in medicines optimization and prescribing might be best targeted towards the more educated nurses, who have multidisciplinary support.

Abstract
Older people are frequently exposed to polypharmacy, inappropriate prescribing, and adverse drug events. Two clinical processes can help geriatricians to optimize and increase the safety of drug prescriptions for older adults: medication reconciliation and medication review. Medication reconciliation provides the best possible medication history and identifies and resolves discrepancies in drug prescriptions. During the medication review, the best possible medication history is crosschecked against other data, including morbidities, patient's preferences, or geriatric syndromes, to produce a personalized medication strategy. Alignment of treatment recommendations with patient preferences and goals through shared decision-making is particularly important in medication review. Medication reconciliation and medication review have proven to be effective, but their broad implementation remains difficult. Indeed, these procedures are time-consuming and require specific skills, coordination between different healthcare professionals, organizations and dedicated means. The involvement of geriatricians therefore remains essential for the successful implementation of medication reconciliation and medication review in geriatric settings and among frail older people.

Abstract
Aging is accompanied by changes in organ degeneration, and susceptibility to multiple diseases, leading to the frequent occurrence of adverse drug reactions resulting from polypharmacy (PP) and potentially inappropriate medications (PIM) in older patients. This study employs a retrospective cohort design and investigates the association of PP with PIM among older patients with high rates of medical utilization. Using records from a national pharmaceutical care database, an experimental group is formed from patients meeting these criteria, who are then offered home pharmaceutical care. Correspondingly, a control group is formed by identifying older patients with regular levels of use of medical services who had been dispensed medications at community pharmacies. Multivariate logistic regression is performed to assess the association between the rate of PIM and variables, including age, gender, and PP. The study finds that experimental PP participants had a higher rate of PIM prescription (odds ratio (OR) = 5.4) than non-PP control participants (all p < 0.001). In clinical practice, additional caution is required to avoid PIMs. Patients engaged in continuously using long-term medication should take precautions in daily life to alleviate related discomforts. Pharmacists should serve as a bridge between patients and physicians to enhance their health and improve their quality of life.

Abstract
Background Medication reconciliation prevents medication errors at care transition points. This process improves communication with general practitioners regarding the reasons for therapeutic changes, allowing those changes to be maintained after hospital discharge. Objective To investigate the impact of medication reconciliation in geriatrics on the sustainability of therapeutic optimization after hospital discharge. Setting This study was conducted in a geriatric unit in a University Hospital Centre in France. Method This was a retrospective study. For 6 months, all patients over 65 years who underwent the process of medication reconciliation performed by a clinical hospital pharmacist and a physician at admission and discharge, were included. A comparison between drug prescriptions at hospital discharge and the first prescription made outside the hospital was made to identify any differences. Main outcome measure The main outcome measures were the provision of the results of the medication reconciliation performed in the hospital to the relevant general practitioner, the subsequent acceptance of that information, the type of medication discrepancies one month after discharge and the therapeutic classes affected by the modifications. Results Among the 112 patients, medication reconciliation allowed us to identify and correct 87 unintentional discrepancies at admission (88% corrected) and 54 at discharge (92% corrected). Patients were discharged to homes or nursing homes (61%), geriatric rehabilitation units (38%) or psychiatric clinics (1%). A general practitioner wrote the first prescription renewal a mean of 36 ± 23 days after discharge, having been made aware of the medication reconciliation in only 24% of the cases (received and taken into account). The impact was a decrease in the number of patients with at least one discrepancy. Twenty-five percent of general practitioners who were aware about the medication reconciliation process accepted all therapeutic changes, while only 7% of those who were not informed did so (p = 0.02). The number of medication discrepancies observed was correlated with the number of medications for which prescriptions were renewed (p < 0.01). Conclusion Medication reconciliation involving therapeutic optimization and the justification of changes is essential to ensure the safety of the prescriptions written for patients. However, its impact after discharge is hampered by the fact that the results are often not received or taken into account by general practitioners. Taking medication reconciliation into account was associated with a significant increase in prescriptions that maintained therapeutic changes made in the hospital, confirming the positive impact of communication between care providers on therapeutic optimization.

Abstract
Schwere Arzneimittelnebenwirkungen stellen mit 5–7 % einen häufigen Grund für eine Krankenhauseinweisung dar. Die Prävalenz von unerwünschten Arzneimittelwirkungen (UAW) während eines stationären Aufenthaltes liegt sogar bei etwa 11,5 %. Die Ursache sind oftmals Medikamentenwechselwirkungen, bedingt durch die Polypharmazie der multimorbiden älteren Patienten. So nimmt ein 65-jähriger Patient im Durchschnitt 5 Medikamente gleichzeitig ein. Aufgrund des zunehmenden Einsatzes von Systemtherapeutika in der Dermatologie und der gleichzeitig zunehmenden Polypharmazie ist das Wissen um Medikamenteninteraktionen für den Dermatologen zur Vermeidung schwerer Arzneimittelnebenwirkungen wesentlich. Dieser Beitrag soll eine Hilfestellung bieten, Patienten und Medikamente mit einem hohen Risiko für schwerwiegende Interaktionen zu identifizieren und dadurch das Auftreten unerwünschter Wirkungen oder auch die Verminderung des therapeutischen Effektes von Wirkstoffen zu vermeiden. Wir möchten darauf hinweisen, dass die folgende Arbeit einzelne Aspekte behandelt und nicht von der Überprüfung einzelner Arzneimittelinteraktionen mittels Interaktionsprogrammen entbindet. Nicht außer Acht gelassen werden sollte, dass neben verschreibungspflichtigen Medikamenten auch Nahrungsmittel, Nahrungsergänzungsmittel und Kräuter zu Interaktionen mit Medikamenten führen können.

Abstract
BACKGROUND Aging populations are often accompanied by comorbidity and polypharmacy, leading to increases in adverse drug reactions (ADRs). We sought to evaluate the causes and characteristics of ADRs in older Korean adults (≥65 years) in comparison to younger individuals (< 65 years). METHODS Of 37,523 cases reported at a Korean pharmacovigilance center from 2011 to 2018, we reviewed 18,842 ADRs of certain or probable causality on the basis of WHO-UMC criteria. We estimated the number of ADRs per 1000 patients exposed to the major culprit drugs, and incidence rate ratios were obtained to assess high- and low-risk medications in older adults. RESULTS In total, 4152 (22.0%) ADRs were reported for 3437 older adults (mean age, 74.6 years and 57.3% female). Tramadol (rate ratio, 1.32; 95% confidence interval [CI], 1.21-1.44; P < 0.001) and fentanyl (1.49, 1.16-1.92, P = 0.002) posed higher risks of ADRs in the older adults, whereas nonsteroidal anti-inflammatory drugs (NSAIDs) (0.35, 0.30-0.40, P < 0.001) and iodinated contrast media (ICM) (0.82, 0.76-0.89, P < 0.001) posed lower risks. Ratios of serious ADRs to NSAIDs (odds ratio, 2.16; 95% CI, 1.48-3.15; P < 0.001) and ICM (2.09, 1.36-3.21, P = 0.001) were higher in the older adults than in the younger patients. Analgesics primarily elicited cutaneous ADRs in the younger patients and gastrointestinal reactions in the older adults. ICM more commonly led to anaphylaxis in the older adults than the younger patients (3.0% vs. 1.6%, P = 0.019). CONCLUSION For early detection of ADRs in older adults, better understanding of differences in the causes and characteristics thereof in comparison to the general population is needed.

A study of medication errors during the prescription stage in the pediatric critical care services of a secondary-tertiary level public hospital. BMC Pediatr 2020; 20:549. [PMID: 33278900 PMCID: PMC7718655 DOI: 10.1186/s12887-020-02442-w] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/24/2020] [Accepted: 11/23/2020] [Indexed: 11/10/2022] Open
Abstract
Background Medication Errors (MEs) are considered the most common type of error in pediatric critical care services. Moreover, the ME rate in pediatric patients is up to three times higher than the rate for adults. Nevertheless, information in pediatric population is still limited, particularly in emergency/critical care practice. The purpose of this study was to describe and analyze MEs in the pediatric critical care services during the prescription stage in a Mexican secondary-tertiary level public hospital. Methods A cross-sectional study to detect MEs was performed in all pediatric critical care services [pediatric emergency care (PEC), pediatric intensive care unit (PICU), neonatal intensive care unit (NICU), and neonatal intermediate care unit (NIMCU)] of a public teaching hospital. A pharmacist identified MEs by direct observation as the error detection method and MEs were classified according to the updated classification for medication errors by the Ruíz-Jarabo 2000 working group. Thereafter, these were subclassified in clinically relevant MEs. Results In 2347 prescriptions from 301 patients from all critical care services, a total of 1252 potential MEs (72%) were identified, and of these 379 were considered as clinically relevant due to their potential harm. The area with the highest number of MEs was PICU (n = 867). The ME rate was > 50% in all pediatric critical care services and PICU had the highest ME/patient index (13.1). The most frequent MEs were use of abbreviations (50.9%) and wrong speed rate of administration (11.4%), and only 11.7% of the total drugs were considered as ideal medication orders. Conclusion Clinically relevant medication errors can range from mild skin reactions to severe conditions that place the patient’s life at risk. The role of pharmacists through the detection and timely intervention during the prescription and other stages of the medication use process can improve drug safety in pediatric critical care services.

Abstract
BACKGROUND/OBJECTIVES Medication review is an important component of the management of older hospital patients. Deprescribing (supervised withdrawal of inappropriate medicines) is one outcome of review. This study aimed to iteratively develop and test the usability of deprescribing guides, which support multidisciplinary clinicians to reduce inappropriate polypharmacy in older inpatients. METHODS Deprescribing guides for hospital clinicians were developed using a novel mixed-methods, ten-step process. Iterative development and usability testing were applied. This included content development through review of the literature; expert consensus through five rounds of feedback using a modified Delphi approach; and usability testing by 16 multidisciplinary hospital clinicians on hypothetical clinical scenarios involving observations, semi-structured interviews, and administration of the System Usability Scale. RESULTS This novel process was used to develop deprescribing guides that facilitate implementation of evidence on deprescribing in routine hospital care. The guides present evidence-based information in a format that aligns with workflows of multidisciplinary hospital clinicians. The guides were adapted for various clinical roles to navigate efficiently to suit differing workflow needs. Guides include unique communication support in the form of "preferred language". Clinicians can use the "preferred language" to apply the evidence to the individual patient and relay decisions between health providers and with patients/carers. The total System Usability Scale score was 80.6 ± 2.0 (mean ± standard error of the mean), indicating excellent usability. Guides have been developed using consistent format for nine medication classes that are common targets for deprescribing and are publicly available. CONCLUSION This study demonstrates a novel approach to the development and implementation of evidence-based recommendations that support deprescribing in routine hospital care.

Abstract
Background Acutely ill older persons are more likely to suffer adverse drug reactions, increasing morbidity, and mortality. The incident adverse drug reactions and their consequences on the length of hospital stay (LOS) in older persons have been little explored. Objective To determine the incident adverse drug reactions in acutely ill older inpatients and their effect on the LOS. Setting Internal medicine service in a Chilean teaching hospital. Method A prospective cohort study was conducted in patients aged ≥ 60 years admitted into the internal medicine service of the Hospital from University of Chile. Characteristics, severity, and causality of adverse drug reactions were assessed. Effect of incident adverse drug reactions on the LOS was determined using multiple Cox regression. A secondary analysis was conducted in patients aged ≥ 65 years. Main outcome measure Incident adverse drug reactions (new events occurring in hospital) and their effect on the LOS in older inpatients. Results A total of 229 acutely ill older persons ≥ 60 years were followed-up. Fifty-six of them suffered 77 adverse drug reactions (incident rate 24.5%; 95% CI: 19.0, 30.5), 70.1% type A. Adverse drug reactions were severe in 5.4% of cases. Causality assessment indicated the majority were probable (57.1%) and 3.9% certain. Cardiovascular agents were the therapeutic class more frequently involved. The most frequent adverse drug reaction was hypotension (19.5%). Patients with adverse drug reactions had a significantly prolonged LOS than those without adverse drug reactions (12.4 ± 11.0 versus 7.3 ± 6.4 days; p < 0.0001) (adjusted Hazard Ratio 0.63; 95% CI: 0.46, 0.87; p < 0.01), respectively. The incidence rate of adverse drug reactions in patients ≥ 65 years was 25.1% (95% CI: 19.0; 32.1), and their occurrence was significantly associated with a prolonged LOS (p < 0.05). Conclusion One in four acutely ill older persons hospitalized in the internal medicine service suffered at least one incident adverse drug reaction, which prolonged the LOS by 5 days. There is a potential to optimize the use of hospital beds and medication safety by preventing adverse drug reactions in geriatric patients.

Abstract
BACKGROUND AND OBJECTIVE The use of multiple medications and altered pharmacokinetics/pharmacodynamics may lead to drug-related problems in members of the older population. The aim of this study is to evaluate the prevalence of, and factors related to, drug-related problems in older urban-living Thai people. METHODS We conducted a cross-sectional study involving 466 participants (aged ≥ 65 years) whose first-time health screening at the Geriatric Excellence Center, King Chulalongkorn Memorial Hospital, Bangkok was between May and October 2019. Participants were interviewed and assessed for drug-related problems by clinical pharmacists. RESULTS In total, 54.5% (254) of the participants were aged 65-69 years and 77.0% (359) of the participants were women. Of the participants, 56.7% had three or more health conditions such as hyperlipidemia (62%), hypertension (46%), and cataract (18%). Fifty-five percent of the participants took five or more health products (polypharmacy) and 16% took ten or more products on a regular basis. Of the 2633 products used, 68% were prescription drugs and 32% were over-the-counter products. The prevalence of drug-related problems according to the criteria suggested by Cipolle-Strand-Morley (2012) was 63.3% (587 drug-related problems). Most of the problems came from: (a) non-adherence (28.6%); (b) needs for additional drug therapy (26.4%); and (c) adverse drug reactions (17.4%). Factors associated with drug-related problems were polypharmacy (odds ratio 2.50, 95% confidence interval 1.60-3.89) and multiple comorbidities [three or more conditions] (odds ratio 2.20, 95% confidence interval 1.41-3.43). CONCLUSIONS The prevalence of drug-related problems in urban-living older people at King Chulalongkorn Memorial Hospital in Bangkok was high. Polypharmacy and multiple comorbidities were significantly related to drug-related problems. To decrease the number of drug-related problems, pharmacists should collaborate with healthcare teams and suggest how to correctly reduce the number of health products being consumed by older people.

Abstract
Purpose To investigate the characteristics of ADRs in patients admitting at the emergency room of a tertiary hospital. Methods We collected the patient records of 1600 emergency room visits of a university hospital in 2018. The patient files were studied retrospectively and all possible ADRs were identified and registered. Patient characteristics, drugs associated with ADRs, causality, severity, preventability, and the role of pharmacogenetics were assessed. Results There were 125 cases with ADRs, resulting in a 7.8% overall incidence among emergency visits. The incidence was greatest in visits among elderly patients, reaching 14% (men) to 19% (women) in the 80–89 years age group. The most common causative drugs were warfarin, acetylsalicylic acid (ASA), apixaban, and docetaxel, and the most common ADRs were bleedings and neutropenia and/or severe infections. Only two of the cases might have been prevented by pharmacogenetic testing, as advised in Clinical Pharmacogenetics Implementation Consortium (CPIC) guidelines. Conclusion The same ATC classes, antithrombotics and cytostatics, were involved in ADRs causing university clinic hospitalizations as those identified previously in drug-related hospital fatalities. It seems difficult to prevent these events totally, as the treatments are vitally important and their risk-benefit-relationships have been considered thoroughly, and as pharmacogenetic testing could have been useful in only few cases.

Abstract
BACKGROUND One of the prevalent treatment modalities for cancer is chemotherapy. Adverse drug reactions, however, are becoming the world's major public health problem. More than half (54.5 percent) of cancer patients need hospitalization for further management, in addition to the increased health-care costs of treatment. The aim of this study was to evaluate adverse drug reactions associated with chemotherapy and related factors in hospitalized paediatric cancer patients in Ethiopia's north-west hospitals. METHODS From July 1, 2017, to August 13, 2019, a cross-sectional study was carried out among 311 paediatric cancer patients at Gondar Comprehensive University, Specialized Hospital and Felegehiwot referral hospital. The data were entered into Epi Info version 7 and exported for further analysis to Statistical Product and Service Solutions (SPSS). To identify associated variables, both the bi-variate and multi-variate logistic regression analyses were computed. Variables with a P-value of less than 0.05 were considered statistically significant in the multivariate logistic regression analysis. RESULTS The overall adverse drug reaction in this study was 41.5 percent ((95% CI: 35.8-47.2%)). Patients who received concomitant medications were at higher risk of experiencing adverse drug reactions (AOR: 2.60 (95% CI: 1.54-4.40)), according to the multivariate logistic regression analysis. Similarly, there was a risk of developing adverse drug reactions in patients taking four or more chemotherapy agents (AOR: 2.67 (95% CI: 1.52-4.68)). In addition, regimens based on etoposide (AOR: 1.99 (95% CI: 0.93-4.27)), mercaptopurine (AOR: 3.91 (95% CI: 1.06-14.46)) and doxorubicin (AOR: 2.32 (95% CI: 1.30-4.15)) were at higher risk for adverse drug reactions in patients. CONCLUSION Adverse drug reactions developed in a significant proportion of the study patients (2 out of 5 patients). Therefore, for pediatric cancer patients on concomitant medications and for patients on etoposide, mercaptopurine and doxorubicin drug regimens, efficient prevention and management of adverse drug reactions should be sought.

Abstract
OBJECTIVES Considering the growing use of imaging modalities and contrast agents, radiologists are prone to encounter adverse drug reactions (ADR). In the current study, we mainly aim to evaluate the knowledge of radiologists regarding pharmacovigilance (PV). Also, we intend to gather information about their previous ADR experiences. Secondarily, we hope to increase the awareness about contrast-medium-related ADRs and attract attention to the importance of properly reporting these ADRs. METHODS A survey was generated by using an online survey webpage, and the relevant link was e-mailed to radiologists and radiology residents. The survey begins with a short explanation about the study. The second section contains questions about PV knowledge level, and the final section aims to gather information about the experienced ADRs. RESULTS The survey was completed by 202 participants. 65.3% stated that they were aware of PV. 24.8% of the participants said that they know the national PV program. 97% told that they knew the term ADR. 66.3% of the participants encountered an ADR. 53.7% of them reported these ADRs. 70.8% of them reported these ADRs to a clinician. CONCLUSIONS Radiologists encounter ADRs almost as frequently as the other doctors. Their awareness about PV is similar with other healthcare professionals. They have fewer information about TUFAM and PvCPs. Radiologists generally prefer to communicate with a clinician about an ADR. Overall condition of radiologists about PV is quite similar with other healthcare professionals and education can improve it, as for the others. ADVANCES IN KNOWLEDGE Radiologists encounters ADRs almost as frequently as the other doctors. Overall condition of radiologists about PV is quite similar with other healthcare professionals and education can improve it, as for the others.

Abstract
Advances in medicines have increased the effectiveness of treatments and the social and cultural authority of doctors. However, as prescribing has become the dominant modality of treatment, the “pharmaceuticalization” of medical practice has often resulted in treatment “at a distance”, with doctors having limited contact with patients. Older and poorer people, who are socially distanced from medical prescribers, suffer more adverse drug reactions (ADRs) than the general population. A team approach to checking patients systematically for ADRs, as detailed in manufacturers’ literature, can minimise medication errors, but regular review is rare. This paper explains the benefits of medicines monitoring to protect older patients from iatrogenic harm, such as over-sedation, falls, or drug-induced Parkinsonism. We show how multidisciplinary initiatives to optimise prescribing can be supported by using a recognised resource—the adverse drug reaction profile (ADRe). The profile identifies and documents patients’ signs and symptoms of putative ADRs. Better monitoring allows professionals to adjust prescribing and respond to identified problems with agility. Implementation of systematic monitoring will require changes to the regulatory regime and better inter-professional cooperation. Providing carers, nurses and pharmacists with a structured system to monitor patients would democratise relevant medical knowledge and help address ageism and the socio-economic health divide.

Abstract
INTRODUCTION Drug-related problems (DRPs) are a major cause of unplanned hospital admissions among elderly people, and transitions of care have been emphasised as a key area for improving patient safety. We have designed a complex clinical pharmacist intervention that targets people ≥75 years of age undergoing transitions of care from hospital to home and primary care. The main objective is to investigate if the intervention can reduce the risk of unplanned drug-related readmission within the first 180 days after the person is discharged from hospital. METHODS AND ANALYSIS This is a randomised, controlled, superiority trial with two parallel arms. A total of 700 people ≥75 years will be assigned to either intervention or routine care (control). The intervention, which aims to find and manage DRPs, is initiated within a week of the person being discharged from hospital and combines repeated medical chart reviews, phone interviews and in some cases medication reviews. People in both study arms may have been the subject of a medication review during their ward stay. As the primary outcome, we will measure time until unplanned drug-related readmission within 180 days of leaving hospital and use log rank tests and Cox proportional hazard models to analyse differences between the groups. Further investigations of subgroup effects and adjustments of the regression models will be based on heart failure and cognitive impairment as prognostic factors. ETHICS AND DISSEMINATION The study has been approved by the Regional Ethical Review Board in Umeå (registration numbers 2017-69-31M, 2018-83-32M and 2018-254-32M). We intend to publish the results with open access in international peer-reviewed journals and present our findings at international conferences. The trial is expected to result in more than one published article and form part of two PhD theses. TRIAL REGISTRATION NUMBER NCT03671629.

Abstract
Objective To undertake a systematic review and meta-analysis examining the impact of polypharmacy on health outcomes in atrial fibrillation (AF). Data sources PubMed and Embase databases were searched from inception until 31 July 2019. Studies including post hoc analyses of prospective randomised controlled trials or observational design that examined the impact of polypharmacy on clinically significant outcomes in AF including mortality, hospitalisations, stroke, bleeding, falls and quality of life were eligible for inclusion. Results A total of six studies were identified from the systematic review, with three studies reporting on common outcomes and used for a meta-analysis. The total study population from the three studies was 33 602 and 37.2% were female. Moderate and severe polypharmacy, defined as 5–9 medicines and >9 medicines, was observed in 42.7% and 20.7% of patients respectively, and was associated with a significant increase in all-cause mortality (Hazard ratio [HR] 1.36, 95% CI 1.20 to 1.54, p<0.001; HR 1.84, 95% CI 1.40 to 2.41, p<0.001, respectively), major bleeding (HR 1.32, 95% CI 1.14 to 1.52, p<0.001; HR 1.68, 95% CI 1.35 to 2.09, p<0.001, respectively) and clinically relevant non-major bleeding (HR 1.12, 95% CI 1.03 to 1.22, p<0.01; HR 1.48, 95% CI 1.33 to 1.64, p<0.01, respectively). There was no statistically significant association between polypharmacy and stroke or systemic embolism or intracranial bleeding. Among other examined outcomes, polypharmacy was associated with cardiovascular death, hospitalisation, reduced quality of life and poorer physical function. Conclusions Polypharmacy is highly prevalent in the AF population and is associated with numerous adverse outcomes. PROSPERO registration number CRD42018105298.

Abstract
Background An adverse drug reaction (ADR) is a response to a medicine that is not intended and is harmful, and which occurs at normal dose levels for humans. Currently, there are no estimates of the population-based prevalence of ADRs in the Kingdom of Saudi Arabia (KSA). Objective The aims of this study were to (1) estimate the population-based prevalence of ADRs in KSA, (2) describe the ADRs experienced by survey respondents, and (3) investigate the level of awareness of the ADR reporting system. Patients and Methods This was a cross-sectional survey using stratified, population-based sampling conducted at a chain of community pharmacies. Results Analysis was conducted on 5228 surveys; 50.17% of respondents were males, and the mean age was 39 ± 15 years (min = 18, max = 98). The sample prevalence of ADRs was 23.45% (95% CI 22.30–24.60%, P < 0.001). The estimated population prevalence (after weighting) was 28.00% (26.10–30.00%). Gastrointestinal disorders were the most commonly reported ADRs (58.73%), followed by general disorders and administration site conditions (19.74%). The largest drug class that was reported to lead to ADRs was nonsteroidal anti-inflammatory drugs (NSAIDs) (11%). Over 19% of the respondents who experienced an ADR required medical intervention to control the suffering induced by the ADR. Of the respondents who experienced an ADR, 371 (30.26%) were aware of the ADR reporting system but only 53 (14.29%) said that they had filed a report in the system. Conclusions Our study estimated that 28% of the population experienced an ADR over a 1-year period in KSA. Risk factors for ADR included certain chronic disease groups and the use of certain classes of medications. Regulatory authorities in KSA intend to conduct more research and deploy educational interventions to reduce ADR rates in KSA. This will hopefully occur in an international context that promotes the standardized measurement of ADRs in the community. A subset of findings from this report was presented in an oral presentation at the Saudi Food and Drug Authority (SFDA) Annual Conference, September 27, 2018. In addition, a subset of findings from this report were presented on a poster at the International Conference of Pharmacoepidemiology and Therapeutic Risk Management (ICPE), August 27, 2019. Electronic supplementary material The online version of this article (10.1007/s40801-020-00186-8) contains supplementary material, which is available to authorized users.

Abstract
BACKGROUND Adverse drug reactions (ADRs) are common, often preventable, and a leading cause of morbidity and mortality. Pharmacovigilance (PV) involves detection, assessment, understanding, and prevention of adverse effects or any other drug-related problem. Education of healthcare professionals (HCPs) involved in drug prescription, dispensing and administration is essential to help prevent and mitigate both ADRs and medication errors and has to be focused on 3 pivotal aspects: •Awareness: All medicines can produce adverse effects. ADRs should always be considered as part of the differential diagnosis if any new adverse condition, symptoms or signs appear after a drug administration or during or after pharmacological treatment. •Knowledge: HCPs must have a sound understanding of the most frequently prescribed drugs and over-the-counter medications, factors that make patients more likely to benefit or more susceptible to harm, as well as of causes of medication errors. •Reporting: HCPs should know how to report ADRs and the role of reporting on regulatory aspects and scientific knowledge. Undergraduate curricula must provide, at a minimum, sufficient skills that warrant the appropriate and safe prescription/dispensing/administration of medications in clinical practice, focusing both on therapeutic effects and prevention of harm. Clinical appraisal skills must include ADRs as differential diagnosis, taking accurate medication history, basic individual causality assessment, identification and proper management of ADRs, and informing patients of possible ADRs. Postgraduate periodic PV training should be mandatory as part of continuing education. Specialised postgraduate education should include advanced contents.

Abstract
OBJECTIVES To develop and validate a tool to predict the risk of an older adult experiencing medication-related harm (MRH) requiring healthcare use following hospital discharge. DESIGN, SETTING, PARTICIPANTS Multicentre, prospective cohort study recruiting older adults (≥65 years) discharged from five UK teaching hospitals between 2013 and 2015. PRIMARY OUTCOME MEASURE Participants were followed up for 8 weeks in the community by senior pharmacists to identify MRH (adverse drug reactions, harm from non-adherence, harm from medication error). Three data sources provided MRH and healthcare use information: hospital readmissions, primary care use, participant telephone interview. Candidate variables for prognostic modelling were selected using two systematic reviews, the views of patients with MRH and an expert panel of clinicians. Multivariable logistic regression with backward elimination, based on the Akaike Information Criterion, was used to develop the PRIME tool. The tool was internally validated. RESULTS 1116 out of 1280 recruited participants completed follow-up (87%). Uncertain MRH cases ('possible' and 'probable') were excluded, leaving a tool derivation cohort of 818. 119 (15%) participants experienced 'definite' MRH requiring healthcare use and 699 participants did not. Modelling resulted in a prediction tool with eight variables measured at hospital discharge: age, gender, antiplatelet drug, sodium level, antidiabetic drug, past adverse drug reaction, number of medicines, living alone. The tool's discrimination C-statistic was 0.69 (0.66 after validation) and showed good calibration. Decision curve analysis demonstrated the potential value of the tool to guide clinical decision making compared with alternative approaches. CONCLUSIONS The PRIME tool could be used to identify older patients at high risk of MRH requiring healthcare use following hospital discharge. Prior to clinical use we recommend the tool's evaluation in other settings.

Abstract
Background: Hospital-acquired medication errors (MEs) are common in health care. Although voluntary reporting is criticized for not producing reliable estimates on ME frequency, it provides valuable knowledge on errors occurring in the medication process. Objective: The purpose of this study was to analyze and determine the risks and outcomes resulting from MEs related to the TOP15 medicines in the Finnish tertiary care units from July 2016 to July 2017. Methods: The data consisting of 1,447 ME reports was organized according to ATC classification, after which TOP15 medicines involved in the reports were selected. Inductive content analysis was performed to the reports. After this, the reports were categorized by ME outcome into five categories and further analyzed accordingly. Results: The most common ME outcome in the reports was "omitted medicine" (33.9%). More than a quarter (27.1%) of ME reports were estimated to cause moderate or severe risk to the patient. When compared with each other, none of the outcome groups were more susceptible to high-risk events (p = 0.71). Of the TOP15 medicines, only Norepinephrine had significantly higher risk of being involved in high-risk events (OR 2.43, 95%CI 1.35-4.61). Conclusion: Voluntary reporting has an important role in the development of medication safety and the overall medication process within organizations. Although majority of the TOP15 medicines were involved in MEs resulting in seemingly high-risk outcomes, they were estimated to be insignificant or minor within the reporting unit. In the future, more emphasis will be needed for the assessment and analysis of the reports for more efficient, real-time detection and response to signals from health care units.

Abstract
BACKGROUND The community pharmacist is a key player in medication reviews of older outpatients. However, it is not always clear which individuals require a medication review. The objective of the present study was to identify high-priority older patients for intervention by a community pharmacist. METHODS As part of their final-year placement in a community pharmacy, pharmacy students conducted 10 interviews each with older adults (aged 65 or over) taking at least five medications daily. The student interviewer also offered to examine the patient's home medicine cabinet. An interview guide was developed by an expert group to assess the difficulties in managing and taking medications encountered by older patients. RESULTS The 141 students interviewed a total of 1370 patients (mean age: 81.5; mean number of medications taken daily: 9.3). Of the 1370 interviews, 743 (54.2%) were performed in the patient's home, and thus also included an examination of the home medicine cabinet. Adverse events were reported by 566 (42.0%) patients. A total of 378 patients (27.6%) reported difficulties in preparing, administering and/or swallowing medications. The inspections of medicine cabinets identified a variety of shortcomings: poorly located cabinets (in 15.0% of inspections), medication storage problems (21.7%), expired medications (40.7%), potentially inappropriate medications (15.0%), several different generic versions of the same drug (19.9%), and redundant medications (20.4%). CONCLUSIONS In a community pharmacy setting, high-priority older patients for intervention by a community pharmacist can be identified by asking simple questions about difficulties in managing, administering, taking or storing medications.

[PMID: 31309522 PMCID: PMC6825075 DOI: 10.1007/s13181-019-00719-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2018] [Revised: 12/30/2018] [Accepted: 12/31/2018] [Indexed: 12/14/2022] Open
Abstract
INTRODUCTION Adverse drug events/reactions (ADE/ADRs) cost more than $30 billion annually and are among the leading causes of death in the USA. Little is known about patients treated at the bedside for ADE/ADR by medical toxicologists. METHODS We conducted a retrospective study of ADE/ADR cases reported to the Toxicology Investigators Consortium (ToxIC) registry between January 1, 2010, and December 31, 2016. Clinical and demographic data were collected including age, sex, circumstances surrounding exposure, suspected offending substance, clinical manifestations, treatment, disposition, and outcome. RESULTS Among 51,440 ToxIC cases during this time period, 673 ADE/ADR cases were reported (337 females). By age, ADE/ADRs were seen most commonly among adults age 19-65 years (442/673, 65.7% of ADE/ADR) and older adults age 65-89 years (134/673, 19.9% of ADE/ADR). 222/673 (33%) of consults for ADE/ADR were seen in the emergency department (ED); 181/673 (26.9%) were seen in the hospital ward; and 160/673 (23.8%) were seen in the intensive care unit (ICU). The most commonly reported sign for ADE/ADR was tachycardia: 51/673 (7.6%), followed by bradycardia: 49/673 (7.3%). Most commonly reported agents associated with ADE/ADR were as follows: 97/673 (14.4%) due to cardiovascular medications; 76/673 (11.3%) due to antipsychotic medications; and 61/673 (9.1%) due to antidepressants. 429/673 (63.7%) of ADE/ADR were reported as due to a single agent, and 212/673 (31.5%) were reported as due to multiple agents. CONCLUSIONS 4.2% of cases managed at the bedside by a consulting toxicologist and reported to the ToxIC registry between 2010 and 2016 had ADE/ADR as the reason for consultation. Agents most commonly involved in ADE/ADRs included cardiovascular medications, antipsychotic medications, and antidepressants.

Nurse-led medicines' monitoring in care homes, implementing the Adverse Drug Reaction (ADRe) Profile improvement initiative for mental health medicines: An observational and interview study. PLoS One 2019; 14:e0220885. [PMID: 31509537 PMCID: PMC6738583 DOI: 10.1371/journal.pone.0220885] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2019] [Accepted: 07/25/2019] [Indexed: 11/28/2022] Open
Abstract
Introduction Preventable adverse effects of medicines often pass unnoticed, but lead to real harm. Intervention Nurse-led monitoring using the structured Adverse Drug Reaction (ADRe) Profile identifies and addresses adverse effects of mental health medicines. Objectives This study investigated the implementation and clinical impact of ADRe, and barriers to and facilitators of sustained utilisation in routine practice. Methods Administration of ADRe was observed for 30 residents prescribed mental health medicines in ten care homes. The study pharmacist reviewed completed ADRes against medication records. Policy context was explored in 30 interviews with service users, nurse managers and strategic leads in Wales. Results Residents were aged 60–95, and prescribed 1–17 (median 9 [interquartile range (IQR) 7–13]) medicines. ADRe identified a median of 18 [IQR 11.5–23] problems per resident and nurses made 2 [1–2] changes to care per resident. For example: falls were reported for 9 residents, and care was modified for 5; pain was identified in 8 residents, and alleviated for 7; all 6 residents recognised as dyspnoeic were referred to prescribers. Nurses referred 17 of 30 residents to prescribers. Pharmacists recommended review for all 30. Doubts about administering ADRe, sometimes expressed by people who had not yet used it, diminished as it became familiar. ADRe was needed to bridge communication between resident, nurses and prescribers. When barriers of time, complacency, and doctors’ non-availability were overcome, reporting with ADRe made prescribers more likely to heed nurses’ concerns regarding residents’ welfare. Clinical gains were facilitated by one-to-one time, staff-resident relationships, and unification of documentation. Implications To our knowledge, ADRe is the only instrument that brings a full account of patients’ problems to medication reviews. This juxtaposition of signs and symptoms against prescriptions facilitates dose adjustments and de-prescribing and leads to: reduced pain and sedation; early identification of problems linked to ADRs, such as falls; and timely medication reviews e.g. for dyspnoea.

Abstract
OBJECTIVES Few studies have investigated the prevalence of adverse drug reactions (ADRs) leading to hospitalisation in Japan. The aim of this study was to determine the prevalence of ADRs leading to hospitalisation and to evaluate the preventability of these ADRs in Japan. DESIGN A single-centre cross-sectional study using electronic medical records. SETTING Acute care hospital. PARTICIPANTS All 1545 consecutive hospital admissions to an internal medicine ward due to acute medical illnesses from April 2017 to May 2018. The median patient age was 79 years (IQR 66-87), and the proportion of women was 47.9%. OUTCOME MEASURES The primary outcome was the proportion of hospitalisations caused by ADRs among all hospitalisations. All suspected cases of ADRs were independently evaluated by two reviewers, and disagreements were resolved by discussion. The causality assessment for ADRs was performed by using the WHO-Uppsala Monitoring Committee criteria. The contribution of ADRs to hospitalisation and their preventability were evaluated based on the Hallas criteria. RESULTS Of the 1545 hospitalisations, 153 hospitalisations (9.9%, 95% CI 8.4% to 11.4%) were caused by 200 ADRs. Cardiovascular agents (n=46, 23.0%), antithrombic agents (n=33, 16.5%), psychotropic agents (n=29, 14.5%) and non-steroidal anti-inflammatory drugs (n=24, 12.0%) accounted for approximately two-thirds of all ADRs leading to hospitalisation. Of 153 hospitalisations caused by ADRs, 102 (66.7%) were judged to be preventable. CONCLUSIONS Similar to other countries, one in every ten hospitalisations is caused by ADRs according to data from an internal medicine ward of a Japanese hospital. Most of these hospitalisations are preventable. Some efforts to minimise hospitalisations caused by ADRs are needed.

Abstract
Objective: The association between polypharmacy and dementia is controversial. This systematic review and meta-analysis aims to summarize existing literature concerning the association between polypharmacy and dementia. Methods: A systematic literature review was performed by searching the EMBASE, PubMed, Scopus and International Pharmaceutical Abstract databases using terms related to polypharmacy and dementia. A meta-analysis was performed using random effect models. Results: Seven studies were included in this meta-analysis. The included studies were of medium to high quality with a potential for publication bias. A strong association between polypharmacy and dementia was found (pooled adjusted risk ratio (aRR) = 1.30 (95% CI: 1.16-1.46), I2 = 68%). Excessive polypharmacy was also strongly associated with dementia (pooled aRR = 1.52 (95% CI: 1.39-1.67), I2 = 24%). Conclusion: Pooled risk estimates from this meta-analysis showed that polypharmacy was associated with dementia. Although the causality of the relationship cannot be concluded from this analysis, the finding encourages the use of multidimensional assessment tools for dementia that includes the number of medications as a component.

Abstract
PURPOSE Multi-morbidity and polypharmacy are common among older people. It is essential to provide a better understanding of the complexity of prescription drug use among older adults to optimise rational pharmacotherapy. Population-based utilisation data in this age group is limited. Using the Danish nationwide health registries, we aimed to characterise drug use among Danish individuals ≥ 60 years. METHODS This is a descriptive population-based study assessing drug prescription patterns in 2015 in the full Danish population aged ≥ 60 years. The use of specific therapeutic subgroups and chemical subgroups and its dependence on age were described using descriptive statistics. Profiles of drug combination patterns were evaluated using latent class analysis. RESULTS We included 1,424,775 residents (median age 70 years, 53% women). Of all the older adults, 89% filled at least one prescription during 2015. The median number of drug groups used was five per person. The most used single drug groups were paracetamol and analogues (34%), statins (33%) and platelet aggregation inhibitors (24%). Eighteen drug profiles with different drug combination patterns were identified. One drug profile with expected use of zero drugs and 11 drug profiles expected to receive more than five different therapeutic subgroup drugs were identified. CONCLUSION The use of drugs is extensive both at the population level and increasing with age at an individual level. Separating the population into different homogenous groups related to drug use resulted in 18 different drug profiles, of which 11 drug profiles received on average more than five different therapeutic subgroup drugs.

Abstract
Background: Prescription and use of inappropriate medications have been identified as a major cause of morbidity among the elderly. Several screening tools have been developed to identify inappropriate medications prescribed for elderly patients. There is dearth of information about the knowledge of Nigerian physicians regarding these screening tools and appropriate prescribing for the elderly in general. The primary objective of this study was to assess the knowledge of Nigerian physicians about these screening tools and appropriate prescribing of medications for the elderly. Methods: The study was a cross-sectional questionnaire-based study conducted among physicians working in Family Medicine and Internal Medicine departments of four tertiary health care facilities in Nigeria. The questionnaire consisted of sections on general characteristics of respondents and their knowledge of four selected screening tools for inappropriate medications in the elderly. Ten clinical vignettes representing different therapeutic areas (using the best option type questions) about medicine use in the elderly were included with a score of 1 and 0 for correct and wrong answers, respectively. The knowledge of respondents was classified as (total score, over 10): poor (score, < 5), average (score, 5-6), and good (score, 7-10). Results: One hundred and five physicians returned completed questionnaires. Twenty percent of respondents knew about Beers criteria, whereas 15.6% were familiar with the STOPP criteria. Majority (83; 84.7%) of the respondents were confident of their ability to prescribeappropriately for elderly patients. The mean knowledge score was 5.3 ± 2.0 with 32 (30.5%), 41 (39%), and 32 (30.5%) having low, average, and good scores, respectively. The association between the knowledge score, duration of practice, and seniority was statistically significant (OR, 3.6, p = .004 and OR, 3; p = .012), respectively. Conclusion: There are significant gaps in the knowledge of Nigerian physicians about screening tools for inappropriate medications. There is a need for stakeholders involved in the care of elderly Nigerian patients to develop new strategies to improve services being offered. These may include introduction of modules on appropriate prescribing in the curriculum of undergraduate and postgraduate medical education and the routine use of some screening tools for inappropriate medications in daily clinical practice.

Abstract
Purpose Aging increases the prevalence of diseases. The elderly population is consequently often exposed to complex medication regimens. Increased drug use is one of the main reasons for drug-related problems (DRPs). The primary objective of this study was to define and classify DRPs, pharmacist interventions, and frequently prescribed medications in relation to possible DRPs in patients admitted to the geriatric ward of a teaching hospital in Turkey. Patients and methods Pharmacist medication review reports for 200 orders of 91 patients (mean age: 80.33±0.46) were analyzed retrospectively. Results A total of 1,632 medications were assessed and 329 interventions were proposed for possible DRPs in 156 orders. A total of 87.5% of the patients used five or more drugs (mean: 8.17±0.23). The number of DRPs per order was higher when polypharmacy was present (1.04±0.15 vs 1.66±0.11, P<0.05). In 71.31% of the cases, adverse drug events were recognized as the problem. The principal cause of possible DRPs was determined as drug interactions (40.12%). Only 22 potentially inappropriate medications were prescribed. The most common interventions included monitoring drug therapy (31.0%), stopping the drug (20.06%), and changing dosage (13.98%). The acceptance rate of pharmacist interventions by treating geriatrician was 85.41%. The most frequently prescribed drugs were for the nervous system, alimentary tract and metabolism, and cardiovascular system (n=358, 314, and 304, respectively). The pharmaceutical forms of 23 drugs were deemed inappropriate by pharmacists. Conclusion Clinical pharmacy services are still not properly implemented in Turkey. The study highlights ways in which clinical pharmacy services can be instrumental in a geriatric ward. The high acceptance rates of pharmacist recommendations concerning a wide variety of DRPs and different classes of drugs indicate that advanced collaboration among geriatricians and pharmacists is possible in interdisciplinary geriatric assessment teams in Turkey.

Abstract
Older people usually present with adverse drug events (ADEs) with nonspecific symptoms such as cognitive decline, recurrent falls, reduced mobility, and/or major deterioration. The aims of this study were to assess the ADEs of patients with dementia and presenting neuropsychiatric/behavioral, and psychological symptoms in dementia (BPSD) and to categorize and identify the principal factors that allow to prevent ADEs, and separately ADEs that result in falls. To that end, a one-year prospective study in a psychogeriatric ward (July 2015 to July 2016) was performed. All patients admitted to this ward were eligible for enrolment. Patients who met any of the following criteria were excluded from the study: Patients without cognitive impairment, a length of stay under 7 days, and palliative or previous psychiatric pathology. We included 65 patients (60% women, 84.9 years ± 6.7) with mild to moderate cognitive impairment, moderate to severe functional dependence, and a high prevalence of geriatric syndromes and comorbidity. A total of 87.7% were taking five or more drugs (mean 9.0 ± 3.1). ADEs were identified during the interdisciplinary meeting and the follow up by clinical record. Sixty-eight ADEs (81.5% patients) were identified, of which 73.5% were not related to falls. From these, 80% were related to drugs of the nervous system. The Naranjo algorithm determined that 90% of ADEs were probable. The severity of the ADEs was Category E in 34 patients (68%). The number of preventable ADE according to the Schumork⁻Thornton test was 58%. The main ADE was drowsiness/somnolence (27.7%). ADEs related to falls represented a 26.5%. The balance between effective treatment and safety is complex in these patients. A medication review in interdisciplinary teams is an essential component to optimize safety prevention.

Abstract
PURPOSE Cardiovascular diseases (CVDs) are extremely common among the elderly, but information on the use of potentially inappropriate medications (PIMs) with cardiovascular risk is scarce. We aimed to determine the prevalence of PIMs with risk of cardiac and cerebrovascular adverse events (CCVAEs), including major adverse cardiac and cerebrovascular events (MACCE). PATIENTS AND METHODS A cross-sectional study was performed using a convenience sample from four long-term care facilities and one community pharmacy in Portugal. Patients were included if they were aged 65 or older and presented at least one type of medication in their medical and pharmacotherapeutic records from 2015 until December 2017. The main outcome was defined as the presence of PIMs with risk of MACCE and was assessed by applying a PIM-MACCE list that was developed from a previous study. All medications included in this list were assessed for their availability in Portugal. RESULTS A total of 680 patients were included. Of those, 428 (63%) were female with a mean age of 78.4±8.1 years. Four-hundred and four (59.4%) patients were taking medications associated with CCVAEs risk (mean =1.7±1.0 drugs/patient), including 264 patients (38.8%) who used drugs with MACCE risk (mean =1.4±0.8 drugs/patient). Fifty percent of patients with a previous history of CVD (n=521) were taking PIMs with risk of CCVAEs, including 30.0% with risk of MACCE. CONCLUSION Our findings show that 50% of patients with previous history of CVD were taking drugs with risk of CCAVEs and 30% with risk of MACCE. More tailored tools for the management of drug therapy in elderly patients with CVD are of major importance in clinical practice.

Abstract
BACKGROUND Our goal was to determine (a) the prevalence of multimorbidity and polypharmacy in patients with cancer and (b) the prevalence, predictability, and preventability of adverse drug reactions (ADRs) causing/contributing to hospitalization. MATERIALS AND METHODS We conducted a 12-month prospective observational study of patients aged ≥16 years admitted to an oncology center. Older adults were aged ≥70 years. RESULTS We enrolled 350 patients: 52.3% (n = 183) female, mean age 63.6 years (SD 12.1), 36.6% (n = 121) aged ≥70 years. Multimorbidity (≥2 conditions) was identified in 96.9%; 68% had ≥5 conditions. The median number of medications was 6 (interquartile range [IQR] 4-8); 47% were prescribed ≥6 medications and 11.4% ≥11 medications. Older adults had higher numbers of comorbid conditions (7 [IQR 5-10] vs. 5 [IQR 3-7]) and were prescribed more medications (median 7 [IQR 4-9] vs. 4 [IQR 2-7]). ADRs caused/contributed to hospitalization in 21.5% (n = 75): 35.8% (n = 72) of emergency admissions and 4.7% (n = 3) of elective admissions. The most common ADRs were neutropenia with infection (25.3%), dyspepsia/nausea/vomiting (20%), and constipation (20%). Causative medications included systemic anticancer therapies (SACTs; 53.3%), opioids (17.3%), corticosteroids (6.7%), and nonsteroidal anti-inflammatory drugs (5.3%). ADR prevalence was similar in older and younger adults secondary to SACTs (8.3% vs. 13.1%), non-cancer medications (10.7% vs. 8.3%), and both (0% vs. 1.3%). ADRs were predictable in 89.3% (n = 67), definitely avoidable in 29.3% (n = 22), and possibly avoidable in 33.3% (n = 25). No association was identified between ADRs and age, gender, daily medication number, length of stay, or death. No ADR predictor variables were identified by logistic regression. CONCLUSION More than 21% of admissions to an oncology service are ADR-related. ADRs are caused by both SACTs and non-cancer-specific medications. The majority are predictable; ≥60% may be preventable. Patients with cancer have high levels of multimorbidity and polypharmacy, which require vigilance for related adverse outcomes. IMPLICATIONS FOR PRACTICE A diagnosis of cancer often occurs in patients with multimorbidity and polypharmacy. Cancer can cause an altered physiological environment, placing patients at risk of drug-drug interactions, drug-disease interactions, and adverse drug reactions (ADRs). This study identified that ADRs caused or contributed to one in five hospital admissions of patients with cancer. ADRs were caused by systemic anticancer therapies (SACTs) in 53.3% of cases and non-cancer medications in 45.4% of cases, and a combination of both in 1.3%. ADRs occurred in similar frequencies in older and younger patients secondary to SACTs (8.3% vs. 13.1%, p = .295), non-SACTs (10.7% vs. 8.3%, p = .107), and a combination of both (0% vs. 1.3%, p = .240). The majority of ADRs were predictable (89.3%) and potentially preventable (62.6%). These findings support the need for increased awareness of medication-related adversity in patients with cancer and interventions to minimize their occurrence, thus supporting the American Society of Clinical Oncology guidelines that recommend adults ≥65 years of age receiving chemotherapy have geriatric assessment to identify medical and medication issues.

The effect of SENATOR (Software ENgine for the Assessment and optimisation of drug and non-drug Therapy in Older peRsons) on incident adverse drug reactions (ADRs) in an older hospital cohort - Trial Protocol. BMC Geriatr 2019; 19:40. [PMID: 30760204 PMCID: PMC6375169 DOI: 10.1186/s12877-019-1047-9] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2018] [Accepted: 01/24/2019] [Indexed: 12/02/2022] Open
Abstract
Background The aim of this trial is to evaluate the effect of SENATOR software on incident, adverse drug reactions (ADRs) in older, multimorbid, hospitalized patients. The SENATOR software produces a report designed to optimize older patients’ current prescriptions by applying the published STOPP and START criteria, highlighting drug-drug and drug-disease interactions and providing non-pharmacological recommendations aimed at reducing the risk of incident delirium. Methods We will conduct a multinational, pragmatic, parallel arm Prospective Randomized Open-label, Blinded Endpoint (PROBE) controlled trial. Patients with acute illnesses are screened for recruitment within 48 h of arrival to hospital and enrolled if they meet the relevant entry criteria. Participants’ medical history, current prescriptions, select laboratory tests, electrocardiogram, cognitive status and functional status are collected and entered into a dedicated trial database. Patients are individually randomized with equal allocation ratio. Randomization is stratified by site and medical versus surgical admission, and uses random block sizes. Patients randomized to either arm receive standard routine pharmaceutical clinical care as it exists in each site. Additionally, in the intervention arm an individualized SENATOR-generated medication advice report based on the participant’s clinical and medication data is placed in their medical record and a senior medical staff member is requested to review it and adopt any of its recommendations that they judge appropriate. The trial’s primary outcome is the proportion of patients experiencing at least one adjudicated probable or certain, non-trivial ADR, during the index hospitalization, assessed at 14 days post-randomization or at index hospital discharge if it occurs earlier. Potential ADRs are identified retrospectively by the site researchers who complete a Potential Endpoint Form (one per type of event) that is adjudicated by a blinded, expert committee. All occurrences of 12 pre-specified events, which represent the majority of ADRs, are reported to the committee along with other suspected ADRs. Participants are followed up 12 (+/− 4) weeks post-index hospital discharge to assess medication quality and healthcare utilization. This is the first clinical trial to examine the effectiveness of a software intervention on incident ADRs and associated healthcare costs during hospitalization in older people with multi-morbidity and polypharmacy. Trial registration number Clinicaltrials.gov NCT02097654, 27 March 2014.

Can screening tools for potentially inappropriate prescriptions in older adults prevent serious adverse drug events? Eur J Clin Pharmacol 2019; 75:627-637. [PMID: 30662995 DOI: 10.1007/s00228-019-02624-1] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2018] [Accepted: 01/02/2019] [Indexed: 01/06/2023]
Abstract
PURPOSE The purpose of the study is to identify and explore risk factors of serious adverse drug events (SADE) and SADE-related admissions in acutely hospitalized multimorbid older adults and assess whether these could have been prevented by adherence to the prescription tools Screening Tool of Older Persons' Prescriptions (STOPP) and The Norwegian General Practice (NORGEP) criteria. METHODS Cross-sectional study of acutely admitted patients to a medical department in a Norwegian regional hospital. Eligible patients were community-dwelling, receiving home care services, and aged 75+, with ≥ 3 chronic diseases. Medications and information regarding the admission were retrieved from the referral letter and medical records, while an expert panel identified SADE using the Common Terminology Criteria for Adverse Events and SADE-related admissions. RESULTS We included 232 patients. Mean (SD) age was 86 (5.7) years, 137 (59%) were female, 121 (52%) used 5-9 drugs whereas 65 (28%) used ≥ 10. We identified SADEs in 72 (31%) of the patients, and in 49 (68%) of these cases, the SADE was considered to cause the hospital admission. A low body mass index (BMI) and a high Cumulative Illness Rating Scale-Geriatrics (CIRS-G) score were independent risk factors for SADEs. Among the SADEs identified, 32 (44%) and 11 (15%) were preventable by adherence to STOPP and NORGEP, respectively. CONCLUSIONS We found a high prevalence of SADE leading to hospitalization. Risk factors for SADE were high CIRS-G and low BMI. STOPP identified more SADEs than NORGEP, but adherence to the prescription tools could only to a limited degree prevent SADEs in this patient group.

Abstract
Background The Beers Criteria were developed with the aim of improving the safety of medicines among older persons. While the association between the Beers' list of potentially inappropriate medicines (PIMs) and adverse drug reactions (ADRs) among older Caucasians is contentious, the ability of the Criteria to predict ADRs among older persons in Africa remains unexplored. Objectives This study aimed to compare the prevalence of PIMs and ADRs among hospitalized older persons in Nigeria and South Africa, and to determine the association between the 2015 American Geriatrics Society-Beers (AGS-Beers) PIMs and ADRs. Methods The medical records of older persons aged ≥60 years who were hospitalized in teaching hospitals in Nigeria and South Africa were randomly selected, and retrospectively evaluated for ADRs by two clinical pharmacists using the Naranjo algorithm. The PIMs were assessed using the 2015 AGS-Beers Criteria. A multivariate logistic regression was used to determine the associated factors for ADRs among the hospitalized older persons, with P<0.05 being considered significant. Results The samples which comprised 268 and 339 hospitalized older persons (mean age 70.53±8.22; 95% CI -0.21 to 2.32 vs mean age 69.49±7.64; 95% CI -0.25 to 2.34, P=0.11) were evaluated in Nigeria and South Africa, respectively. The PIMs among the older persons in Nigeria were 32.1% (86/268) and 30.1% (102/339, OR=0.91, 95% CI 0.64-1.29, P=0.6) for South Africa; 13.8% (37/268) of the hospitalized older persons in Nigeria experienced 43 cases of ADRs compared to 9.1% (31/339) in South Africa (95% CI 0.38-1.04, P=0.07). The multivariate analysis showed no association between PIMs and ADRs among the hospitalized older persons in Nigeria (OR=1.48 95% CI 0.70-3.17, P=0.31) and South Africa (OR=1.09, 95% CI 0.48-2.49, P=0.83). Conclusion The 2015 AGS-Beers PIMs were not associated with ADRs among the hospitalized older persons in Nigeria and South Africa. However, physicians should be cautious when prescribing certain medications in the AGS-Beers list.

Abstract
Improving the quality of medication use and medication safety in older adults is an important public health priority and is of paramount importance for clinicians who care for them. We selected four important articles from 2017 that address these issues to annotate and critique, and we discuss the broader implications for optimizing medication use. A longer list of articles is given in an online appendix. The first study provides national data on the prevalence of central nervous system-active medication polypharmacy in older adults and how this has changed over a 9-year period (2004-2013). The second study characterizes prevalence of and factors associated with nonadherence to antiepileptic drugs in 36,912 older adults with epilepsy, with an emphasis on minorities. The third study describes the extent of antibiotic use in residents of 381 long-term care facilities (LTCF) in British Columbia, Canada, from 2007 to 2014. Finally, we discuss a meta-analysis of 42 studies that evaluated the prevalence of hospital admissions caused by adverse drug reactions in older adults. This article is intended to provide a narrative review of important publications on medication use quality and safety for clinicians and researchers committed to optimizing medication use in older adults.

Incidence, causes, and consequences of preventable adverse drug reactions occurring in inpatients: A systematic review of systematic reviews. PLoS One 2018; 13:e0205426.

Abstract
BACKGROUND Preventable adverse drug reactions (PADRs) in inpatients are associated with harm, including increased length of stay and potential loss of life, and result in elevated costs of care. We conducted an overview of reviews (i.e., a systematic review of systematic reviews) to determine the incidence of PADRs experienced by inpatients. Secondary review objectives were related to assessment of the effects of patient age, setting, and clinical specialty on PADR incidence. METHODS The protocol was registered in PROSPERO (CRD42016043220). We performed a search of Medline, Embase, and the Cochrane Library, limiting languages of publication to English and French. We included published systematic reviews that reported quantitative data on the incidence of PADRs in patients receiving acute or ambulatory care in a hospital setting. The full texts of all primary studies for which PADR data were reported in the included reviews were obtained and data relevant to review objectives were extracted. Quality of the included reviews was assessed using the AMSTAR-2 tool. Both narrative summaries of findings and meta-analyses of primary study data were undertaken. RESULTS Thirteen systematic reviews encompassing 37 unique primary studies were included. Across primary studies, the PADR incidence was highly varied, ranging from 0.006 to 13.3 PADRs per 100 patients, with a pooled incidence estimate of 0.59 PADRs per 100 patients. Substantial heterogeneity was present across both reviews and primary studies with respect to review/study objectives, patient age, hospital setting, medical discipline, definitions and assessment tools used, event detection methods, endpoints of interest, and units of measure. Thirteen primary studies used prospective event detection methods and had a pooled PADR incidence of 3.13 (2.87-3.38) PADRs per 100 patients; however, extreme statistical heterogeneity (I2 = 97%) indicated this finding should be considered with caution. Subgroup meta-analyses demonstrated that PADR incidence varied significantly with event detection method (prospective > retrospective > voluntary reporting methods), hospital setting (ICU > wards), and medical discipline (medical > surgical). High statistical heterogeneity (I2 > 80%) was present across all analyses, indicating results should be interpreted with caution. Effects of patient age could not be assessed due to poor reporting of age groups used in primary studies. DISCUSSION The method of event detection appeared to significantly influence PADR incidence, with prospective methods having the highest reported PADR rate. This finding is in agreement with the background literature. High methodological and statistical heterogeneity across primary studies evaluating adverse drug events reduces the validity of the overall PADR incidence derived from the meta-analyses of the pooled data. Data pooled from studies using only prospective methods of event detection should provide an overall estimate closest to the true PADR incidence; however, our estimate should be considered with caution due to the statistical heterogeneity found in this group of studies. Future studies should employ prospective methods of detection. This review demonstrates that the true overall incidence of PADRs is likely much greater than the overall pooled incidence estimate of 0.59 PADRs per 100 patients obtained when event detection method was not taken into consideration.

Abstract
INTRODUCTION Improved medicines' management could lead to real and sustainable improvements to the care of older adults. The overuse of mental health medicines has featured in many reports, and insufficient patient monitoring has been identified as an important cause of medicine-related harms. Nurse-led monitoring using the structured adverse drug reaction (ADRe) profile identifies and addresses the adverse effects of mental health medicines. Our study investigates clinical impact and what is needed to sustain utilisation in routine practice in care homes. METHODS AND ANALYSIS This process evaluation will use interviews and observations with the participants of all five homes involved in earlier research, and five newly recruited homes caring for people prescribed mental health medicines. The ADRe profile is implemented by nurses, within existing resources, to check for signs and symptoms of ADRs, initiate amelioration and share findings with pharmacists and prescribers for medication review. Outcome measures are the numbers and nature of problems addressed and understanding of changes needed to optimise clinical gain and sustain implementation. Data will be collected by 30 observations and 30 semistructured interviews. Clinical gains will be described and narrated. Interview analysis will be based on the constant comparative method. ETHICS AND DISSEMINATION Ethical approval was conferred by the National Health Service Wales Research Ethics Committee. If the ADRe profile can be sustained in routine practice, it has potential to (1) improve the lives of patients, for example, by reducing pain and sedation, and (2) assist in early identification of problems caused by ADRs. Therefore, in addition to peer-reviewed publications and conferences, we shall communicate our findings to healthcare professionals, policy-makers and sector regulators.

Abstract
The power and influence of healthcare systems comes largely from the ability to prescribe efficacious medicine. However, medicine can sometimes cause harm rather than bring benefits. Systematically checking patients for the adverse effects of medicines, as listed in manufacturers' literature, would protect patients from iatrogenic harm, but this is rarely undertaken. We argue for the benefits of this approach using the example of the prescription of antipsychotics to older adults. Prescribing antipsychotics to control challenging behaviours associated with dementia is a controversial matter, and regulatory intervention is under discussion. Improved regulatory systems could protect against iatrogenic harm, such as over-sedation, falls, tremor, or drug-induced Parkinsonism. However, measuring the impact and outcomes of regulatory interventions has proved difficult, not least because there are rarely systematic records of all adverse effects of medicines. We indicate how regulatory initiatives to reduce antipsychotic prescribing can be supported by systematic monitoring and documentation of patients' signs and symptoms of putative adverse drug reactions. Monitoring documentation then provides the rationale and support for professionals' responses to identified problems. Longitudinal monitoring records would improve understanding of the impact and outcomes of adverse drug reactions (ADRs) on health and wellbeing, and the many costs of ADRs.

Abstract
Background: In adulthood, depression is the most common type of mental illness and will be the second leading cause of disease by 2020. Major depression dramatically affects the function of the central nervous system and degrades the quality of life, especially in old age. Several mechanisms underlie the pathophysiology of depressive illness, since it has a multifactorial etiology. Human and an-imal studies have demonstrated that depression is mainly associated with imbalances in neurotransmitters and neurotrophins, hypothalamic-pituitary-adrenal axis alterations, brain volume changes, neurogenesis dysfunction, and dysregulation of in-flammatory pathways. Also the gut microbiota may influence mental health outcomes. Although depression is not a consequence of normal aging, depressive disorders are common in later life, even if often undi-agnosed or mis-diagnosed in old age. When untreated, depression reduces life expectancy, worsens medical illnesses, en-hances health care costs and is the primary cause of suicide among older people. To date, the underpinnings of depression in the elderly are still to be understood, and the pharmacological treatment is the most commonly used therapy. Objective: Since a sedentary lifestyle and poor eating habits have recently emerged as crucial contributors to the genesis and course of depression, in the present review, we have focused on the effects of physical activity and omega-3 fatty acids on depressive illness in the elderly. Results: A growing literature indicates that both exercise and dietary interventions can promote mental health throughout one’s lifespan. Conclusion: There thus emerges the awareness that an active lifestyle and a balanced diet may constitute valid low-cost pre-vention strategies to counteract depressive illness in the elderly.

Abstract
AIMS We aimed to develop a standardized chart review method to identify drug-related hospital admissions (DRA) in older people caused by non-preventable adverse drug reactions and preventable medication errors including overuse, underuse and misuse of medications: the DRA adjudication guide. METHODS The DRA adjudication guide was developed based on design and test iterations with international and multidisciplinary input in four subsequent steps: literature review; evaluation of content validity using a Delphi consensus technique; a pilot test; and a reliability study. RESULTS The DRA adjudication guide provides definitions, examples and step-by-step instructions to measure DRA. A three-step standardized chart review method was elaborated including: (i) data abstraction; (ii) explicit screening with a newly developed trigger tool for DRA in older people; and (iii) consensus adjudication for causality by a pharmacist and a physician using the World Health Organization-Uppsala Monitoring Centre and Hallas criteria. A 15-member international Delphi panel reached consensus agreement on 26 triggers for DRA in older people. The DRA adjudication guide showed good feasibility of use and achieved moderate inter-rater reliability for the evaluation of 16 cases by four European adjudication pairs (71% agreement, κ = 0.41). Disagreements arose mainly for cases with potential underuse. CONCLUSIONS The DRA adjudication guide is the first standardized chart review method to identify DRA in older persons. Content validity, feasibility of use and inter-rater reliability were found to be satisfactory. The method can be used as an outcome measure for interventions targeted at improving quality and safety of medication use in older people.
