Can supporting health literacy reduce medication-related harm in older adults?

Enhancing the quality of medicine handover at hospital discharge: a priority setting workshop

BACKGROUND

When a patient is discharged from hospital it is essential that their general practitioner (GPs) and community pharmacist are informed of changes to their medicines. This necessitates effective communication and information-sharing between hospitals and primary care clinicians.

OBJECTIVE

To identify priority medicine handover issues and solutions to inform the co-design and development of a multifaceted intervention.

METHOD

A modified nominal group technique was used to reach consensus on medicine handover priority areas. The first hour of an interactive 2-hr workshop focused on ranking pre-identified issues drawn from literature. In the second hour, participants identified solutions that they then ranked from highest to lowest priority through an online platform. Descriptive statistics were used to analyse workshop data.

RESULTS

In total 32 participants attended the workshop including hospital doctors (n = 8, 25.0%), GPs and hospital pharmacists (n = 6 each, 18.8%), consumers and community pharmacists (n = 4 each, 12.5%), and both hospital and aged care facility nurses (n = 2 each 6.3%). From the list of 23 issues, the highest ranked issue was high workload and time pressures impacting the discharge process (22/32). From the list of 36 solutions, the participants identified two solutions that were equally ranked highest (12/27 each). They were mandating that patients leave hospital with a discharge summary, including medication reconciliation information and, developing an integrated information technology system where medication summary and notes are accessible for primary, secondary and tertiary health provider.

CONCLUSION

The consensus process highlighted challenges in hospital procedures where potential solutions may be implemented through co-design of a multifaceted intervention to improve medicine handover quality.

Keeping patients safe through medication review and management in the community

BACKGROUND

There are numerous publications on inpatient medication errors. However, little focus is given to medication errors that occur at home.

AIMS

To describe and analyse the types of medication errors among community-dwelling patients following their discharge from an acute care hospital in Singapore.

METHOD

This is a retrospective review of a 'good catch' reporting system from December 2018 to March 2022. Medication-related errors were extracted and analysed.

FINDINGS

A total of 73 reported medication-related error incidents were reviewed. The mean age of the patients was 78 years old (SD=9). Most patients managed their medications independently at home (45.2%, n=33). The majority of medications involved were cardiovascular medications (51.5%, n=50). Incorrect dosing (41.1%, n=39) was the most common medication error reported. Poor understanding of medication usage (35.6%, n=26) and lack of awareness of medication changes after discharge (24.7%, n=18) were the primary causes of the errors.

CONCLUSION

This study's findings provide valuable insights into reducing medication errors at home. More attention must be given to post-discharge care, especially to preventable medication errors. Medication administration and management education can be emphasised using teach-back methods.

Medication errors by caregivers in the homes of children discharged from a pediatric department in Ghana

Background

Medication errors (MEs) by caregivers at home are a cause of morbidity and mortality, shortly after discharge from the hospital.

Objectives

The objective of this study was to determine the rate and types of MEs at the homes of children discharged from a hospital in Ghana and to explore the factors associated with these errors.

Design

This was a cross-sectional study of infants and children discharged from the hospital to review medication administration practices.

Methods

Caregivers of children discharged from the hospital after at least 24 hours of admission were interviewed at their homes about medication administration practices. The study assessed potential harm associated with MEs made by caregivers using the Harm Associated with Medication Error Classification tool. The Least Absolute Shrinkage and Selection Operator regression were used to identify the variables associated with MEs.

Results

A total of 95 children (mean age: 28.6 months, 52.6% female) and their caregivers were included. Overall, 65 (68.4%) children experienced one or more MEs. Out of a total of 232 medications reviewed, 102 (44.0%) (95% CI: 37.6-50.4) were associated with a ME. The top two errors, wrong time errors and errors in the frequency of dosing were, 45.1% and 21.6%, respectively. Understanding the information on the disease condition being treated and the medicines dispensed was associated with committing fewer MEs. The number of medicines prescribed was associated with a higher likelihood of MEs. Out of 102 MEs, 48 (47.1%) were assessed as posing potentially no harm, 26 (25.5%) minor harm, 15 (14.7%) moderate harm, and 13 (12.8%) serious harm to the patients. Importantly, none of the MEs were assessed as posing potentially severe or life-threatening harm to the patients.

Conclusion

MEs in children following discharge are high, and systems should be developed to prevent these errors.

Impact of Limited English Proficiency on Medication-Related Problems and Emergency Room Visits Among Community-Dwelling Older People

Background Older people have higher risk of experiencing medication-related problems (MRPs), leading to increased morbidity, health care use, and mortality. Few studies have examined the pathway between limited English proficiency (LEP) among older people and health service use through MRPs. Objective This study aimed to explore the association of LEP among Latino older people with MRPs and their relationship to emergency room (ER) visits. Methods Researchers used secondary enrollment data from a community medication program for older people (N = 180). Researchers conducted linear regression to examine the relationship between ethnicity/English proficiency and MRPs, and logistic regression to explore the association between MRPs and ER visits. Generalized structural equation modeling (GSEM) with bootstrapping was used to test the indirect effect between LEP Latino through MRPs to ER visits. Results The sample included 70% non-Latino participants, 12% English-speaking Latinos, and 18% LEP Latinos. Analysis LEP Latinos were associated with having 3.4 more MRPs than non-Latino participants, after controlling for covariates. Additionally, each additional MRP was associated with a 10% increased probability of having an ER visit. The GSEM results illustrated there was a significant indirect effect between LEP through MRPs to ER visits (β = 0.27, 95% CI 0.07-0.61). Conclusion Though LEP was not directly related to increased ER visits, it may have inhibited the ability of Latinos to read and understand medication instructions, contributing to their elevated risk of experiencing MRPs, thus indirectly increasing potential risks of having ER visits.

Development of a patient-centred medication management model for polymedicated home-dwelling older adults after hospital discharge: results of a mixed methods study

OBJECTIVE

This study aimed to investigate medication management among polymedicated, home-dwelling older adults after discharge from a hospital centre in French-speaking Switzerland and then develop a model to optimise medication management and prevent adverse health outcomes associated with medication-related problems (MRPs).

DESIGN

Explanatory, sequential, mixed methods study based on detailed quantitative and qualitative findings reported previously.

SETTING

Hospital and community healthcare in the French-speaking part of Switzerland.

PARTICIPANTS

The quantitative strand retrospectively examined 3 years of hospital electronic patient records (n=53 690 hospitalisations of inpatients aged 65 years or older) to identify the different profiles of those at risk of 30-day hospital readmission and unplanned nursing home admission. The qualitative strand explored the perspectives of older adults (n=28), their informal caregivers (n=17) and healthcare professionals (n=13) on medication management after hospital discharge.

RESULTS

Quantitative results from older adults' profiles, affected by similar patient-related, medication-related and environment-related factors, were enhanced and supported by qualitative findings. The combined findings enabled us to design an interprofessional, collaborative medication management model to prevent MRPs among home-dwelling older adults after hospital discharge. The model comprised four interactive fields of action: listening to polymedicated home-dwelling older adults and their informal caregivers; involving older adults and their informal caregivers in shared, medication-related decision-making; empowering older adults and their informal caregivers for safe medication self-management; optimising collaborative medication management practices.

CONCLUSION

By linking the retrospective and prospective findings from our explanatory sequential study involving multiple stakeholders' perspectives, we created a deeper comprehension of the complexities and challenges of safe medication management among polymedicated, home-dwelling older adults after their discharge from hospital. We subsequently designed an innovative, collaborative, patient-centred model for optimising medication management and preventing MRPs in this population.

Patient safety as a global health priority

Patient safety is a discipline that has arisen in response to the increasing complexity of health care delivery and the associated increase in patient harm. Adverse health care events are a serious problem, causing significant harm to the patient and increasing health care costs. The World Health Organization has identified patient safety as one of the key priorities for world health. The current review presents the historical background that led to the formation of the discipline of patient safety, the determinants of adverse events in medical practice, and the main tools for dealing with them.

Consumers' self-reported adherence to directions for non-prescription medicines and the role of risk perception

BACKGROUND

Non-prescription medicines (NPMs), while relatively safe, are responsible for a small but significant proportion of medication misadventure and inappropriate use may lead to avoidable healthcare cost. Some consumers vary their use of NPMs from the directions provided on packaging or advice from healthcare professionals. Consumers may use NPMs at lower doses or less frequently than directed because of the risk of side effects.

PURPOSE

This study aimed to develop and validate a self-report measure for the extent to which consumers' follow directions (FDs) for NPMs. Secondly, it aimed to explore the relationship between risk perception towards NPMs and following directions.

METHODS

A cross-sectional study was administered online to participants who belong to an Australian agency which conducts consumer research. Participants were Australian adults who had used NPMs within the last month. Items for the FD-NPM scale were developed and validated. Exploratory factor analysis and confirmatory factor analysis were used to validate the FD-NPM scale. Structural equation modelling (SEM) was employed to explore the relationships between risk perception, covariates, and FDs.

RESULTS

There were 403 participants recruited. Less than 20% "always" or "often" self-reported following directions for dose, frequency, or duration of use. Factor analyses confirmed that there are two moderately positively correlated dimensions of FD-NPM (r = 0.46), which were named underuse and overuse. That is, consumers who self-reported underuse of non-prescription medicines were also more likely to self-report overuse. Consumers with high-risk perception towards NPMs, those who were younger and those who were more educated had a greater tendency to not follow directions.

CONCLUSION

A new self-report measure, the FD-NPM scale was developed and validated. That people who perceives NPMs to be harmful, tend to underuse and more concerningly, overuse them, is of great interest to clinicians and policymakers who are required to manage risk communications.

Low health literacy and multiple medications in community-dwelling older adults: a population-based cohort study

OBJECTIVES

Adequate health literacy is important for patients to manage chronic diseases and medications. We examined the association between health literacy and multiple medications in community-dwelling adults aged 50 years and older in England.

DESIGN, SETTINGS AND PARTICIPANTS

We included 6368 community-dwelling people of median age 66 years from the English Longitudinal Study of Ageing. Health literacy was assessed at wave 5 (2010/11) with 4 questions concerning a medication label. Four correct answers were categorised as adequate health literacy, otherwise low. Data on medications were collected at wave 6 (2012/13). To examine the difference in the number of medications between low and adequate health literacy, we used zero-inflated negative binomial regression, estimating odds ratio (OR) for zero medication and incidence rate ratios (IRR) for the number of medications, with 95% CIs. Associations were adjusted for demographic, socioeconomic and health characteristics, smoking and cognitive function. We also stratified the analysis by sex, and age (50-64 and ≥65 years). To be comparable with preceding studies, multinomial regression was fitted using commonly used thresholds of polypharmacy (0 vs 1-4, 5-9, ≥10 medications).

RESULTS

Although low health literacy was associated with a lower likelihood of being medication-free (OR=0.64, 95% CI: 0.45 to 0.91), health literacy was not associated with the number of medications among those at risk for medication (IRR=1.01, 95% CI: 0.96 to 1.05), and this finding did not differ among younger and older age groups or women. Among men, low health literacy showed a weak association (IRR=1.06, 95% CI: 0.99 to 1.14). Multinomial regression models showed graded risks of polypharmacy for low health literacy.

CONCLUSIONS

Although there was no overall association between health literacy and the number of medications, this study does not support the assertion that low health literacy is associated with a notably higher number of medications in men.

The Source of Purchased Medications and Its Impact on Medication Mistakes and Hospitalizations

Older adults self-administer prescribed medication regimens to treat chronic diseases, which can lead to mismanagement, medication-related harm, and hospitalization. Using the National Health and Aging Trends Study (NHATS) dataset, we examined the extent to which the medication source could impact the occurrence of self-reported medication mistakes and hospitalizations in community-dwelling adults aged ≥65 years who managed medications independently (N = 3,899). The majority (65%) picked up medications, 18% had medications delivered, and 17% used both methods. Compared to those picking up their medications, those using delivery only were less likely to have a hospital stay (odds ratio [OR] = 0.61, 95% confidence interval [CI] [0.51, 0.94]) but had no difference in odds of medication mistakes (OR = 1.13, 95% CI [0.57, 2.23]). Those using both methods were more likely to report hospital stays (OR = 1.43, 95% CI [1.11, 1.85]) and medication mistakes (OR = 1.65, 95% CI [1.00, 2.73]). Health care providers should consider medication source when assessing older adults' ability to safely self-manage medications. [Research in Gerontological Nursing, 15(2), 69-75.].

Ideal instruments used to measure health literacy related to medication use: A systematic review

BACKGROUND

Prior studies showed the association between inadequate health literacy (HL) and poor medication-related skills, while none of the published studies have reviewed and compared the existing instruments used to measure medication-related HL. This systematic review comprehensively summarizes the existing instruments that assess medication-related HL.

OBJECTIVES

To identify appropriate HL instruments related to medication use as screening tools for enhancing patients' ability to use medications correctly.

METHODS

This review retrieved medication-related HL instruments that were published between 2000 and 2019 from three databases (i.e., PubMed, Scopus, EMBASE) and by hand-searching. The PRISMA procedure was followed as well as the SURGE guideline to assess the quality of studies. Psychometric properties, HL dimensions, and types of medication information gleaned from the items in three types of HL instruments (i.e., general, disease-specific, medication-specific) were compared to identify appropriate medication-related HL instruments.

RESULT

Forty-eight instruments were identified from 44 studies, whereas 70.8% instruments were either disease- or medication-specific HL instruments. Most instruments with different sample sizes showed certain an extent of reliability and validity. The distributions of HL dimensions and types of medication information among the relevant items were varied across different types of instruments. The five instruments (named as the 16SQ, AKQ-CQ, DHLKI, AKT, and ChMLM) were identified as the most appropriate instruments for three types of medication-related HL, respectively. These appropriate instruments consistently covered items related to HL dimensions of literacy and comprehension and medication-related information regarding dosing, treatment indication, and side effects/precautions.

CONCLUSION

Of 48 identified instruments mainly derived from disease- or medication-specific studies, the five most appropriate medication-related HL instruments were identified to support clinicians in facilitating patients' correct medication use. Further confirmation to explore the usefulness among these instruments are needed.

Suitability of patient education materials on proton-pump inhibitors deprescribing: a focused review

PURPOSE

Engaging patients in the process of deprescribing is a necessity. Several patient education materials have been developed for this purpose. The aim of this study was to assess the suitability of the existing patient education materials for proton-pump inhibitors deprescribing.

METHODS

We conducted a targeted inventory of the available materials on scientific literature and known repositories. We evaluated their suitability with the Suitability Assessment of Materials (SAM) instrument. Materials were rated independently by two researchers and then discussed until consensus was reached.

RESULTS

Seven patient education materials were identified. Three materials (42.9%) were deemed "superior" and 4 (57.1%) were deemed "adequate". Ratings were generally good in the categories of content, learning stimulation, motivation, typography and layout. The major weaknesses included the use of inappropriate graphics and the too demanding required reading grade level. These may decrease patient attention and comprehension and therefore the effectiveness of education materials.

CONCLUSIONS

Suitability of the patient education materials on proton-pump inhibitors deprescribing is overall satisfactory. Greater attention on readability, graphics and inclusion of summaries will be needed for development of future materials.

Antidepressant use and its relationship with current symptoms in a population-based sample of older Australians

BACKGROUND

Australia has the second highest per capita users of antidepressants globally, and their use is pronounced in older Australians. A better understanding of antidepressant use in older adults is important because the elderly are often prescribed multiple drugs, without review, for long periods.

METHODS

This study analysed questionnaire data obtained from the Personality and Total Health through life project. Individual respondent data was linked to Pharmaceutical Benefits Scheme (PBS) records. Associations between self-reported medicine use and current symptoms with antidepressant dispensing were examined.

RESULTS

1275 participants aged over 65 were included in the final analysis. One hundred and forty-six (11.5%) participants were dispensed an antidepressant within the specified timeframe. Of those, 38.4% self-reported that they use medicine for depression, 12.3% for anxiety, 17.8% for both depression and anxiety, 6.2% for sleep problems and 3.4% for pain. One fifth of those dispensed an antidepressant did not self-report use of the medicine. Being female or reporting symptoms of depression, anxiety or suicidality were significant predictors of being on an antidepressant. Increasing pain severity was also associated with increased likelihood of being on an antidepressant.

LIMITATIONS

We have presented a cross-sectional analysis, which can only provide associations between current symptoms and medicine use. We have only assessed respondents who received their scripts with PBS concession, which limits generalizability.

CONCLUSION

Our analysis highlights the high use of antidepressants in the elderly for various reasons. Our findings also uncovered a high amount of under-reporting of antidepressant use by respondents.

Availability and readability of patient education materials for deprescribing: An environmental scan

AIMS

To identify and evaluate content and readability of freely available online deprescribing patient education materials (PEMs).

METHODS

Systematic review of PEMs using MEDLINE, Embase, CINAHL, PsycINFO and The Cochrane Library of Systematic Reviews from inception to 25 September 2017 to identify PEMs. Additionally, deprescribing researchers and health professionals were surveyed to identify additional materials. Known repositories of materials were searched followed by a systematic Google search (22-28 January 2018). Materials were evaluated using an approach informed by the Patient Education Material Assessment Tool and the International Patient Decision Aids Standards Inventory. Readability of text-based materials was assessed using the US-based Gunning-Fog Index and Flesch-Kincaid Grade level.

RESULTS

Forty-eight PEMs were identified. PEMs addressing deprescribing of medications for symptom control (81%) were most common. Preventative medications were rarely addressed and material (39%) focused on older people. Only 37% of PEMs provided information about both potential benefits (e.g. reducing risk of side effects) and harms (e.g. withdrawal symptoms, increased risk of disease) of deprescribing, while 40% focussed on benefits only. Readability indices indicated an average minimum reading level of Grade 12. Option Grids and Decision Aids (mean reading level below Grade 10) were most suitable for people with average literacy levels.

CONCLUSIONS

Over 1/3 of deprescribing PEMs present potential benefits and harms of deprescribing indicating most of the freely available materials are not balanced. Most PEMs are pitched above average reading levels making them inaccessible for low health literacy populations.

Medication Adherence and Its Association with Health Literacy and Performance in Activities of Daily Livings among Elderly Hypertensive Patients in Islamabad, Pakistan

Background and Objective: Medication non-adherence is a preventable reason for treatment failure, poor blood pressure control among hypertensive patients and the geriatric population owing to poor physical activity is more vulnerable strata. The objective of this study is to investigate medication adherence and its associated factors among Pakistani geriatric hypertensive patients. Methods: A cross-sectional survey-based study was conducted at the out-patient department of the cardiac center from May 2018 to August 2018. A universal sampling technique was used to approach patients and 262 eligible consented patients were interviewed to collect information about socio-demographics, health, and disease-related characteristics using a structured questionnaire. The Morisky Levine Green test was used for the assessment of medication adherence. The Barthel index and single item literacy screener (SILS) was used to measure performance in activities of daily living and health literacy respectively. Chi-square tests and multivariate binary logistic regression analysis were performed to find factors by using SPSS version 20. Results: Of the total 262 participants, about 38.9% (n = 102) were scored 4 and considered adherent while 61.1% (n = 160) were considered as non-adherent. In logistic regression analysis, self-reported moderate (OR = 3.538, p = 0.009) and good subjective health (OR = 4.249, p = 0.008), adequate health literacy (OR = 3.369, p < 0.001) and independence in performing activities of daily living (OR = 2.968, p = 0.002) were found to be independent predictors of medication adherence among older hypertensive patients. Conclusion: Medication adherence among the older hypertensive population in Pakistan is alarmingly low. This clearly requires patient-centered interventions to overcome barriers and educating them about the importance of adherence.

Patient-focused interventions to support vulnerable people using oral anticoagulants: a narrative review

The aim of this review was to identify patient-focused interventions that have been trialed to support vulnerable patient populations taking oral anticoagulants (warfarin and the direct-acting oral anticoagulants (DOACs)) such as older persons (65 years and over), those with limited health literacy, and those from culturally and linguistically diverse (CALD) backgrounds. This review also aimed to report on the effects of these interventions on outcomes relevant to the use of anticoagulant therapy. Original articles published between 1 January 1995 and 30 June 2017 were identified using several electronic databases such as Medline, Ovid, Embase, Scopus, Cochrane, and Google Scholar. The following terms were used for the three-tiered search: Tier 1, elderly, aged, older adult, geriatrics; Tier 2, health literacy, literacy, low health literacy, low English proficiency, patient literacy; and Tier 3, ethnicity, ethnic, ethnic groups, CALD, culturally and linguistically diverse, NESB, non-English speaking background, race, racial groups, religion, religious groups, and minority groups. The terms for each tier were combined with the following terms: anticoagulants, anticoagulation, warfarin, apixaban, dabigatran, rivaroxaban, DOACS, new oral anticoagulants, novel oral anticoagulants, patient care, patient knowledge, comprehension, patient education, patient participation, and communication. A total of 41 studies were identified. Most of the interventions identified included older persons taking warfarin who were monitored using the international normalized ratio (INR) and who received patient education. Many interventions reported a significant positive impact on patients' knowledge, reduction in the number of adverse events caused by hemorrhage, and better INR control. More research on patient-focused interventions is needed that includes patients with limited health literacy, those from CALD backgrounds, and family members and caregivers of patients taking oral anticoagulants.

Race/Ethnicity, Socioeconomic Status, and Polypharmacy among Older Americans

Background: Very few studies with nationally representative samples have investigated the combined effects of race/ethnicity and socioeconomic position (SEP) on polypharmacy (PP) among older Americans. For instance, we do not know if prevalence of PP differs between African Americans (AA) and white older adults, whether this difference is due to a racial gap in SEP, or whether racial and ethnic differences exist in the effects of SEP indicators on PP. Aims: We investigated joint effects of race/ethnicity and SEP on PP in a national household sample of American older adults. Methods: The first wave of the University of Michigan National Poll on Healthy Aging included a total of 906 older adults who were 65 years or older (80 AA and 826 white). Race/ethnicity, SEP (income, education attainment, marital status, and employment), age, gender, and PP (using 5+ medications) were measured. Logistic regression was applied for data analysis. Results: Race/ethnicity, age, marital status, and employment did not correlate with PP; however, female gender, low education attainment, and low income were associated with higher odds of PP among participants. Race/ethnicity interacted with low income on odds of PP, suggesting that low income might be more strongly associated with PP in AA than white older adults. Conclusions: While SEP indicators influence the risk of PP, such effects may not be identical across diverse racial and ethnic groups. That is, race/ethnicity and SEP have combined/interdependent rather than separate/independent effects on PP. Low-income AA older adults particularly need to be evaluated for PP. Given that race and SEP have intertwined effects on PP, racially and ethnically tailored interventions that address PP among low-income AA older adults may be superior to universal interventions and programs that ignore the specific needs of diverse populations. The results are preliminary and require replication in larger sample sizes, with PP measured directly without relying on individuals’ self-reports, and with joint data collected on chronic disease.

EuGMS Task and Finish group on Fall-Risk-Increasing Drugs (FRIDs): Position on Knowledge Dissemination, Management, and Future Research

Falls are a major public health concern in the older population, and certain medication classes are a significant risk factor for falls. However, knowledge is lacking among both physicians and older people, including caregivers, concerning the role of medication as a risk factor. In the present statement, the European Geriatric Medicine Society (EuGMS) Task and Finish group on fall-risk-increasing drugs (FRIDs), in collaboration with the EuGMS Special Interest group on Pharmacology and the European Union of Medical Specialists (UEMS) Geriatric Medicine Section, outlines its position regarding knowledge dissemination on medication-related falls in older people across Europe. The EuGMS Task and Finish group is developing educational materials to facilitate knowledge dissemination for healthcare professionals and older people. In addition, steps in primary prevention through judicious prescribing, deprescribing of FRIDs (withdrawal and dose reduction), and gaps in current research are outlined in this position paper.

Strategies to promote public engagement around deprescribing

Many seniors remain unaware that certain medications may be harmful, despite high rates of polypharmacy and inappropriate medication use among community-dwelling older adults. Patient education is an effective method for reducing the use of inappropriate medications. Increasing public awareness and engagement is essential for promoting shared decision-making to deprescribe. The Canadian Deprescribing Network was created to address the lack of a systematic pan-Canadian initiative to implement deprescribing among older Canadians. The Canadian Deprescribing Network deliberately included patient advocates in its organization from the outset, in order to ensure a key strategic focus on public awareness and education. In this paper, we present the processes and activities rolled out by the Canadian Deprescribing Network as a blueprint model for engaging the public on deprescribing. Embedded within the structure of the network, the subcommittee on public awareness and engagement implements an action plan that includes needs assessments, population surveys, focus groups, deprescribing fairs, national stakeholders' meetings, public lectures and monthly exchanges with community champions and seniors' organizations. Educational materials and online media have been developed based on the answers to the questions: what information do seniors need about deprescribing? who should this information be delivered to? who needs to deliver the message? and how should seniors be engaged in deprescribing? In conjunction with seniors' organizations, members of the Network have iteratively refined key deprescribing messages, disseminated information about deprescribing, engaged the press and created a grass roots-driven public awareness and education campaign across Canada. Over 3000 seniors and seniors' organizations are involved, with over 25,000 educational tools being distributed across the country.

Can doctors identify older patients at risk of medication harm following hospital discharge? A multicentre prospective study in the UK

AIMS

Medication-related harm (MRH) is common in older adults following hospital discharge. In resource-limited health systems, interventions to reduce this risk can be targeted at high-risk patients. This study aims to determine whether (1) doctors can predict which older patients will experience MRH requiring healthcare following hospital discharge, (2) clinical experience and confidence in prediction influence the accuracy of the prediction.

METHODS

This was a multicentre observational prospective study involving five teaching hospitals in England between September 2013 and November 2015. Doctors discharging patients (aged ≥65 years) from medical wards predicted the likelihood of their patient experiencing MRH requiring healthcare (hospital readmission or community healthcare) in the initial 8-week period post-discharge. Patients were followed up by senior pharmacists to determine MRH occurrence.

RESULTS

Data of 1066 patients (83%) with completed predictions and follow-up, out of 1280 recruited patients, were analysed. Patients had a median age of 82 years (65-103 years), and 58% were female. Most predictions (85%) were made by junior doctors with less than 5 years' clinical experience. There was no relationship between doctors' predictions and patient MRH (OR 1.10, 95% CI 0.82-1.46, P = 0.53), irrespective of years of clinical experience. Doctors' predictions were more likely to be accurate when they reported higher confidence in their prediction, especially in predicting MRH-associated hospital readmissions (OR 1.58, 95% CI 1.42-1.76, P < 0.001).

CONCLUSIONS

Clinical judgement of doctors is not a reliable tool to predict MRH in older adults post-discharge.
