Measurement properties of utility-based health-related quality of life measures in cardiac rehabilitation and secondary prevention programs: a systematic review.

PURPOSE: To identify utility-based patient-reported outcome measures (PROMs) for assessing health-related quality of life (HRQoL) in cardiac rehabilitation and secondary prevention programs (CR) and appraise existing evidence on their measurement properties. Secondly, to link their items to the International Classification of Functioning Disability and Health (ICF) and the International Consortium of Health Outcome Measures (ICHOM) domains for cardiovascular disease (CVD). METHODS: Eight databases were searched. The review followed the COSMIN and JBI guidelines for measurement properties systematic reviews and PRISMA 2020 reporting guidelines. Non-experimental and observational empirical studies of patients ≥ 18 years of age with CVD undergoing CR and assessed quality of life (QoL) or HRQoL using utility-based PROMs or one accompanied by health state utilities were included. RESULTS: Nine PROMs were identified with evidence on measurement properties for three measures: the German translations of SF-12, EQ-5D-5L, and MacNew heart disease HRQoL questionnaire. There was moderate quality evidence for responsiveness and hypothesis testing of the SF-12 and EQ-5D-5L, and high-quality evidence for responsiveness and hypothesis testing for the MacNew. All items of SF-12 and EQ-5D were linked to ICF categories, but four items of the MacNew were not classified or defined. All the PROM domains were mapped onto similar constructs from the ICHOM global sets. CONCLUSION: Three utility-based PROMs validated in CR were identified: the German versions of the EQ-5D and SF-12 and the MacNew questionnaire. These PROMs are linked to a breadth of ICF categories and all ICHOM global sets. Additional validation studies of PROMs in CR are required.

Clinical effectiveness of cardiac rehabilitation and barriers to completion in patients of low socioeconomic status in rural areas: A mixed-methods study.

OBJECTIVE: To investigate cardiac rehabilitation utilisation and effectiveness, factors, needs and barriers associated with non-completion. DESIGN: We used the mixed-methods design with concurrent triangulation of a retrospective cohort and a qualitative study. SETTING: Economically disadvantaged areas in rural Australia. PARTICIPANTS: Patients (≥18 years) referred to cardiac rehabilitation through a central referral system and living in rural areas of low socioeconomic status. MAIN MEASURES: A Cox survival model balanced by inverse probability weighting was used to assess the association between cardiac rehabilitation utilization and 12-month mortality/cardiovascular readmissions. Associations with non-completion were tested by logistic regression. Barriers and needs to cardiac rehabilitation completion were investigated through a thematic analysis of semi-structured interviews and focus groups (n = 28). RESULTS: Among 16,159 eligible separations, 44.3% were referred, and 11.2% completed cardiac rehabilitation. Completing programme (HR 0.65; 95%CI 0.57-0.74; p < 0.001) led to a lower risk of cardiovascular readmission/death. Living alone (OR 1.38; 95%CI 1.00-1.89; p = 0.048), having diabetes (OR 1.48; 95%CI 1.02-2.13; p = 0.037), or having depression (OR 1.54; 95%CI 1.14-2.08; p = 0.005), were associated with a higher risk of non-completion whereas enrolment in a telehealth programme was associated with a lower risk of non-completion (OR 0.26; 95%CI 0.18-0.38; p < 0.001). Themes related to logistic issues, social support, transition of care challenges, lack of care integration, and of person-centeredness emerged as barriers to completion. CONCLUSIONS: Cardiac rehabilitation completion was low but effective in reducing mortality/cardiovascular readmissions. Understanding and addressing barriers and needs through mixed methods can help tailor cardiac rehabilitation programmes to vulnerable populations and improve completion and outcomes.

Clinical Effectiveness and Utilisation of Cardiac Rehabilitation After Hospital Discharge: Data Linkage Analysis of 84,064 Eligible Discharged Patients (2016-2021).

BACKGROUND: Despite the highest levels of evidence on cardiac rehabilitation (CR) effectiveness, its translation into practice is compromised by low participation. AIM: This study aimed to investigate CR utilisation and effectiveness in South Australia. METHODS: This retrospective cohort study used data linkage of clinical and administrative databases from 2016 to 2021 to assess the association between CR utilisation (no CR received, commenced without completing, or completed) and the composite primary outcome (mortality/cardiovascular re-admissions within 12 months after discharge). Cox survival models were adjusted for sociodemographic and clinical data and applied to a population balanced by inverse probability weighting. Associations with non-completion were assessed by logistic regression. RESULTS: Among 84,064 eligible participants, 74,189 did not receive CR, with 26,833 of the 84,064 (31.9%) participants referred. Of these, 9,875 (36.8%) commenced CR, and 7,681 of the 9,875 (77.8%) completed CR. Median waiting time from discharge to commencement was 40 days (interquartile range, 23-79 days). Female sex (odds ratio [OR] 1.12; 95% CI 1.01-1.24; p=0.024), depression (OR 1.17; 95% CI 1.05-1.30; p=0.002), and waiting time >28 days (OR 1.15; 95% CI 1.05-1.26; p=0.005) were associated with higher odds of non-completion, whereas enrolment in a telehealth program (OR 0.35; 95% CI 0.31-0.40; p<0.001) was associated with lower odds of non-completion. Completing CR (hazard ratio [HR] 0.62; 95% CI 0.58-0.66; p<0.001) was associated with a lower risk of 12-month mortality/cardiovascular re-admissions. Commencing without completing was also associated with decreased risk (HR 0.81; 95% CI 0.73-0.90; p<0.001), but the effect was lower than for those completing CR (p<0.001). CONCLUSIONS: Cardiac rehabilitation (CR) attendance is associated with lower all-cause mortality/cardiovascular re-admissions, with CR completion leading to additional benefits. Quality improvement initiatives should include promoting referral, women's participation, access to telehealth, and reduction of waiting times to increase completion.

Development and evaluation of a co-designed website for delivering interactive self-directed cardiac rehabilitation.

AIMS: The aim of this study is to report on the development and evaluation of the co-designed website for delivering interactive self-directed cardiac rehabilitation (CR). METHODS AND RESULTS: Multi-method user experience design framework was used to co-design the web application and complete usability testing. Participants were recruited based on their eligibility for CR. Thematic analysis collected the participants' design specifications and lived experiences. The System Usability Scale (SUS) was administered at the completion of the website development and the usability testing workshops. This collected the participants' perceptions of the website's effectiveness, efficiency, and their satisfaction. Website development and usability testing workshops included 39 and 35 participants with a mean age of 66.5 (SD 11.7) and 68.6 (SD 11.2), respectively. Both genders were equally represented across both workshops with 19 (48.7%) and 16 (45.7%) women. Workshop themes guided the design process. The mean SUS scores increased from 66.7 (SD 16.8) to 73.6 (21), P = 0.26. Easiness of use (P = 0.03), integration of the website functions (P ≤ 0.001), and consistency (P = 0.038) significantly improved from website development to usability testing. The proportion of participants rating it as excellent increased from 20.5% to 42.9%, P = 0.11. CONCLUSION: The evolution of our CR website development was completed with an improvement in usability. Upcoming evaluation of this intervention will report on its effectiveness.

An innovative business model using established Medicare items for delivery of cardiac rehabilitation: A value proposition for primary care.

BACKGROUND: Approximately 70% of Australians do not attend cardiac rehabilitation (CR). A potential solution is integrating CR into primary care OBJECTIVE: To propose a business model for primary care providers to implement CR using current Medicare items. DISCUSSION: Using the chronic disease management plan, general practitioners (GPs) complete four clinical assessments at 1-2 weeks, 8-12 weeks, and 6 and 12 months after discharge. The net benefit of applying this model, compared with claiming the most used standard consultation Item 23, in Phase II CR is up to $505 per patient and $543 in Phase III CR. The number of rural GPs providing CR in partnership with the Country Access To Cardiac Health (CATCH) through the GP hybrid model has increased from 28 in 2021 to 32 in 2022. This increase might be attributed to this value proposition. The biggest limitation is access to allied health services in the rural areas.

Effectiveness of alternative vs traditional exercises on cardiac rehabilitation program utilization in women with or at high risk of cardiovascular disease: a systematic review protocol.

OBJECTIVE: This review will evaluate the effectiveness of alternative vs traditional forms of exercise on cardiac rehabilitation program utilization and other outcomes in women with or at high risk of cardiovascular disease. INTRODUCTION: Exercise-based cardiac rehabilitation programs improve health outcomes in women with or at high risk of cardiovascular disease. However, such programs are underutilized worldwide, particularly among women. Some women perceive traditional gym-based exercise in cardiac rehabilitation programs (eg, typically treadmills, cycle ergometers, traditional resistance training) to be excessively rigorous and unpleasant, resulting in diminished participation and completion. Alternative forms of exercise such as yoga, tai chi, qi gong, or Pilates may be more enjoyable and motivating exercise options for women, enhancing engagement in rehabilitation programs. However, the effectiveness of these alternative exercises in improving program utilization is still inconsistent and needs to be systematically evaluated and synthesized. INCLUSION CRITERIA: This review will focus on randomized controlled trials of studies measuring the effectiveness of alternative vs traditional forms of exercise on cardiac rehabilitation program utilization as well as clinical, physiological, or patient-reported outcomes in women with or at high risk of cardiovascular disease. METHODS: The review will follow the JBI methodology for systematic reviews of effectiveness. Databases including MEDLINE (Ovid), CINAHL (EBSCOhost), Cochrane CENTRAL, Embase (Ovid), Emcare (Ovid), Scopus, Web of Science, LILACS, and PsycINFO (Ovid) will be searched. Two independent reviewers will screen articles and then extract and synthesize data. Methodological quality will be assessed using JBI's standardized instruments. GRADE will be used to determine the certainty of evidence. REVIEW REGISTRATION: PROSPERO CRD42022354996.

Effectiveness of nurse-led interventions versus usual care to manage hypertension and lifestyle behaviour: a systematic review and meta-analysis.

AIMS: This review aimed to investigate the effectiveness of nurse-led interventions vs. usual care on hypertension management, lifestyle behaviour, and patients' knowledge of hypertension and associated risk factors. METHODS: A systematic review with meta-analysis was conducted following Joanna Briggs Institute (JBI) guidelines. MEDLINE (Ovid), EmCare (Ovid), CINAHL (EBSCO), Cochrane library, and ProQuest (Ovid) were searched from inception to 15 February 2022. Randomized controlled trials (RCTs) examining the effect of nurse-led interventions on hypertension management were identified. Title and abstract, full text screening, assessment of methodological quality, and data extraction were conducted by two independent reviewers using JBI tools. A statistical meta-analysis was conducted using STATA version 17.0. RESULTS: A total of 37 RCTs and 9731 participants were included. The overall pooled data demonstrated that nurse-led interventions may reduce systolic blood pressure (mean difference -4.66; 95% CI -6.69, -2.64; I2 = 83.32; 31 RCTs; low certainty evidence) and diastolic blood pressure (mean difference -1.91; 95% CI -3.06, -0.76; I2 = 79.35; 29 RCTs; low certainty evidence) compared with usual care. The duration of interventions contributed to the magnitude of blood pressure reduction. Nurse-led interventions had a positive impact on lifestyle behaviour and effectively modified diet and physical activity, but the effect on smoking and alcohol consumption was inconsistent. CONCLUSION: This review revealed the beneficial effects of nurse-led interventions in hypertension management compared with usual care. Integration of nurse-led interventions in routine hypertension treatment and prevention services could play an important role in alleviating the rising global burden of hypertension.

Cardiac rehabilitation, physical activity, and the effectiveness of activity monitoring devices on cardiovascular patients: an umbrella review of systematic reviews.

AIMS: To consolidate the evidence on the effectiveness of activity-monitoring devices and mobile applications on physical activity and health outcomes of patients with cardiovascular disease who attended cardiac rehabilitation (CR) programmes. METHODS AND RESULTS: An umbrella review of published randomized controlled trials, systematic reviews, and meta-analyses was conducted. Nine databases were searched from inception to 9 February 2022. Search and data extraction followed the JBI methodology for umbrella reviews and PRISMA guidelines. Nine systematic reviews met the inclusion criteria, comparing outcomes of participants in CR programmes utilizing devices/applications, to patients without access to CR with devices/applications. A wide range of physical, clinical, and behavioural outcomes were reported, with results from 18 712 participants. Meta-analyses reported improvements in physical activity, minutes/week [standardized mean difference (SMD) 0.23, 95% confidence interval (CI) 0.10-0.35] and activity levels (SMD 0.29, 95% CI 0.07-0.51), and a reduction in sedentariness [risk ratio (RR) 0.54, 95% CI 0.39-0.75] in CR participants, compared with usual care. Of clinical outcomes, the risk of re-hospitalization reduced significantly (RR 0.49, 95% CI 0.27-0.89), and there was reduction (non-significant) in mortality (RR 0.27, 95% CI 0.05-1.54). From the behavioural outcomes, reviews reported improvements in smoking behaviour (RR 0.87, 95% CI 0.67-1.13) and total diet quality intake (RR 0.79, 95% CI 0.66-0.94) among CR patients. CONCLUSIONS: The use of devices/applications was associated with increase in activity, healthy behaviours, and reductions in clinical indicators. Although most effect sizes indicate limited clinical benefits, the broad consistency of the narrative suggests devices/applications are effective at improving CR patients' outcomes.

Measurement properties of utility-based health-related quality-of-life measures in cardiac rehabilitation: a systematic review protocol.

OBJECTIVE: This review will identify and appraise existing evidence on the measurement properties of utility-based health-related quality-of-life (HRQoL) measures used in cardiac rehabilitation programs. The review will map the measure domains against the International Classification of Functioning, Disability and Health and the International Consortium of Health Outcome Measures domains for cardiovascular disease. INTRODUCTION: Improving HRQoL is an international key indicator for delivering high-quality and person-centered secondary prevention programs. Many instruments and measures assess HRQoL in individuals undergoing cardiac rehabilitation. Utility-based measures are suitable for calculating quality-adjusted life years, a required outcome metric in cost-utility analysis. Cost-utility analysis requires the use of utility-based HRQoL measures. However, there is no consensus on which utility-based measure is best for populations undergoing cardiac rehabilitation. INCLUSION CRITERIA: Eligible studies will include patients aged ≥18 years with cardiovascular disease who are undergoing cardiac rehabilitation. Empirical studies that assess quality of life or HRQoL using a utility-based, health-related, patient-reported outcome measure or a measure accompanied by health state utilities will be eligible. Studies must report at least 1 of the following measurement properties: reliability, validity, responsiveness. METHODS: This review will follow the JBI methodology for systematic reviews of measurement properties. The following databases will be searched from inception to the present: MEDLINE, Emcare, Embase, Scopus, CINAHL, Web of Science Core Collection, Informit, PsyclNFO, REHABDATA, and the Cochrane Library. Studies will be critically appraised using the The COnsensus-based Standards for the selection of health status Measurement INstruments (COSMIN) risk of bias checklist. The review will be reported in line with the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) guidelines. REVIEW REGISTRATION: PROSPERO CRD42022349395.

The effectiveness of interactive cardiac rehabilitation web applications versus usual care on programme completion in patients with cardiovascular disease: A systematic review and meta-analysis of randomised controlled trials.

INTRODUCTION: Although available evidence demonstrates positive clinical outcomes for patients attending and completing cardiac rehabilitation, the effectiveness of interactive cardiac rehabilitation web applications on programme completion has not been systematically examined. METHODS: This JBI systematic review of effects included studies measuring effectiveness of interactive cardiac rehabilitation web applications compared to telephone, and centre-based programmes. Outcome data were pooled under programme completion and clinical outcomes (body mass index, low-density lipoproteins, and blood pressure). Databases including MEDLINE (via Ovid), Cochrane Library, Scopus (via Elsevier) and CINAHL (via EBSCO) published in English were searched. Articles were screened and reviewed by two independent reviewers for inclusion, and the JBI critical appraisal tool and Grading of Recommendations Assessment, Development and Evaluation tool were applied to appraise and assess the certainty of the findings of the included studies. A meta-analysis of the primary and secondary outcomes used random effects models. RESULTS: In total, nine studies involving 1175 participants who participated in web-based cardiac rehabilitation to usual care were identified. The mean critical appraisal tool score was 76 (standard deviation: 9.7) with all (100%) studies scoring >69%, and the certainty of evidence low. Web-based programmes were 43% more likely to be completed than usual care (risk ratio: 1.43; 95% confidence interval: 0.96, 2.13) There was no difference between groups for clinical outcomes. DISCUSSION: Despite the relatively small number of studies, high heterogeneity and the limited outcome measures, the results appeared to favour web-based cardiac rehabilitation with regard to programme completion.

Effectiveness of activity-monitoring devices in patients with cardiovascular disease participating in cardiac rehabilitation programs: an umbrella review protocol.

OBJECTIVE: The objective of the review is to investigate the effect of activity-monitoring devices and mobile applications on physical activity and health outcomes of patients with cardiovascular disease who are participating in cardiac rehabilitation programs. INTRODUCTION: Supporting patients with cardiovascular conditions to achieve and maintain healthy physical activity levels is the cornerstone of cardiac rehabilitation programs. The effectiveness of activity-monitoring devices and mobile applications (such as physical activity interventions) utilizing consumer-grade monitoring devices and applications to support patients to improve exercise levels during and after program completion has been investigated. Several systematic reviews evaluating the effectiveness of monitoring devices and applications have indicated varying clinical impact, depending on patient characteristics, stage of rehabilitation, and type of intervention. INCLUSION CRITERIA: This review will consider systematic reviews and/or meta-analyses of randomized controlled trials of patients who participated in cardiac rehabilitation programs that included a physical activity intervention that incorporated activity monitoring using electronic devices and/or mobile applications and reported activity and patient health outcomes. METHODS: MEDLINE, Embase, Sport Discus, the Cochrane Database of Systematic Reviews, Scopus, CINAHL, the International Network of Agencies for Health Technology Assessment database, Epistemonikos, and Web of Science will be searched from inception to the present. PROSPERO will be searched for unpublished reviews. Articles will be screened by two independent reviewers for inclusion, and methodological quality will be assessed using a JBI critical appraisal tool. Data will be extracted from systematic reviews and a data synthesis of findings will be presented. The certainty will be assessed using the Grading of Recommendations Assessment, Development and Evaluation approach. SYSTEMATIC REVIEW REGISTRATION NUMBER: PROSPERO CRD42022298877.

Effectiveness of cardiac rehabilitation programs in improving medication adherence in patients with cardiovascular disease: a systematic review protocol.

OBJECTIVE: The objective of this review is to measure the effectiveness of cardiac rehabilitation programs versus standard care on medication adherence in patients with cardiovascular disease. INTRODUCTION: Poor adherence to long-term medications increases the risk of morbidity and mortality, and decreases quality of life in patients with cardiovascular diseases. Several strategies have been trialed to improve medication adherence, one of which is cardiac rehabilitation programs. Although evidence has indicated that such programs increase medication adherence, the extent of their effectiveness and translation into clinical practice is not well documented. Our systematic review will collect and analyze the available evidence for clinical practice implementation. INCLUSION CRITERIA: The search will aim to locate randomized controlled trials. Where randomized controlled trials are not available, quasi-experimental studies, case-control studies, observational studies, and other study designs will be included. Studies that measure effectiveness of cardiac rehabilitation programs compared with standard care on medication adherence in cardiovascular disease patients will be included. METHODS: Databases, including MEDLINE (Ovid), Emcare (Ovid), Embase (Ovid), Cochrane CENTRAL, Scopus, CINAHL (EBSCO), and unpublished sources will be searched. Articles in English and non-English-language articles with an English abstract, published from database inception to the present, will be included. Articles will be screened and reviewed by 2 independent reviewers for inclusion. Critical appraisal tools will be applied to the included studies. Data will be extracted using the appropriate extraction tools and synthesized for the objectives of the study. SYSTEMATIC REVIEW REGISTRATION NUMBER: PROSPERO CRD42021284705.

Effectiveness of telehealth versus standard care on health care utilization, health-related quality of life, and well-being in homebound populations: a systematic review protocol.

OBJECTIVE: The objective of the review is to determine the effectiveness of telehealth versus in-person care on health care utilization, health-related quality of life, and well-being in homebound populations. INTRODUCTION: Globally, an increasing number of people are becoming homebound. These individuals experience high levels of social isolation and deterioration of their well-being. Reports from homebound people and recent publications suggest that this cohort may benefit from accessing telehealth solutions from their homes to treat and prevent serious issues affecting their health and well-being. This review will synthesize the evidence on the effectiveness of telehealth compared to standard care (in-person care) on health care utilization, health-related quality of life, and well-being in homebound populations. INCLUSION CRITERIA: Studies including people living in community settings, whose daily life is physically limited to the boundary of their homes because of their ongoing health, energy, and psychosocial or socio-functional impairments will be considered for inclusion. METHODS: This review will consider relevant, peer-reviewed primary experimental and quasi-experimental studies, with no limit on language or date. Databases to be searched include MEDLINE, Embase, PsycINFO, CINAHL, the Cochrane Central Register of Controlled Trials (CENTRAL), Scopus, LILACS, JBI Evidence Synthesis (hand-searched for further studies), and Web of Science. Two independent reviewers will be involved in study selection and data extraction. Eligible studies will be critically appraised for methodological quality using the relevant JBI critical appraisal checklists, and statistical meta-analysis will be done (where possible). Findings will be presented in narrative form. SYSTEMATIC REVIEW REGISTRATION NUMBER: PROSPERO CRD42021289578.

Efficacy and safety of statins in ethnic differences: a lesson for application in Indigenous Australian patient care.

Although statins are effective in treating high cholesterol, adverse effects do occur with their use. Efficacy and tolerability vary among statins in different ethnic groups. Indigenous Australians have a high risk for cardiovascular and kidney diseases. Prescribing statins to Indigenous Australians with multi-morbidity requires different strategies to increase efficacy and reduce their toxicity. Previous studies have reported that Indigenous Australians are more susceptible to severe statin-induced myopathies. However, there is a lack of evidence in the underlying genetic factors in this population. This review aims to identify: inter-ethnic differences in the efficacy and safety of statins; major contributing factors accounting for any identified differences; and provide an overview of statin-induced adverse effects in Indigenous Australians.

Opioid prescribing and risk of drug-opioid interactions in older discharged patients with polypharmacy in Australia.

Background Opioids are commonly prescribed to managing chronic pain in older persons. However, these patients are often at risk of drug-opioid interactions due to polypharmacy. Objectives To identify the prevalence of opioid prescribing and drug-opioid interactions in poly-medicated older patients and factors associated with opioid prescribing. Setting Patients were included if they were admitted to the Royal Adelaide Hospital between September 2015 and August 2016, aged ≥ 75 years and took ≥ 5 medications at discharge. Methods After ethics approval, data of were retrospectively collected from case notes. The Charlson Comorbidity Index and Drug Burden Index were determined and opioids were classified as strong or weak. The association between opioid use and concurrent medications was computed using logistic regression and the results presented as odds ratios (OR) and 95% confidence intervals (95% CI), adjusted for age, sex, Charlson Comorbidity Index, number of prescribed medications and modified-Drug Burden Index. Main outcome measure Association between concurrent medications and opioid prescribing. Results 15,000 geriatric admissions were identified, of which 1192 were included. A total of 283 (23.7%) patients were prescribed opioids, with oxycodone accounting for 56% of these prescriptions. Opioid users were prescribed more medications (11.2 vs. 9.0, P < 0.001) and had higher Drug Burden Index (1.2 vs. 0.14, P < 0.001) compared to non-users. Opioid use was associated with concurrent prescription of antiepileptics (OR = 1.7, 95% CI 1.1-2.6), and negatively associated with Charlson Comorbidity Index (OR = 0.9, 95% CI 0.8-0.98) and concurrent use of antipsychotics (OR = 0.5, 95% CI 0.3-0.9) and beta blocking agents (OR = 0.4, 95% CI 0.3-0.6). Conclusions Strong opioids were prescribed more often than weak opioids and opioid users presented with characteristics and concurrent medications which increased the risk of opioid related adverse drug effects.

Prevalence and Factors Associated with Analgesic Prescribing in Poly-Medicated Elderly Patients.

BACKGROUND: Pain is common in older patients and management guidelines rarely consider the effect of multiple comorbidities and concurrent medications on analgesic selection. OBJECTIVES: The objectives of this study were to identify the prevalence and pattern of analgesic prescribing and associated factors in older patients with polypharmacy. METHODS: Older patients (aged ≥ 75 years) admitted to the Royal Adelaide Hospital between September 2015 and August 2016 and with polypharmacy were included and their comorbidities and medications prescribed at discharge were recorded. Drug Burden Index and Charlson Comorbidity Index were calculated. The number of medications that increased the risk of orthostatic hypotension were recorded. Logistic regression was used to compute the association between analgesic use and participant characteristics, and results were presented as odds ratios and 95% confidence intervals, adjusted for age, sex, Charlson Comorbidity Index, Drug Burden Index and orthostatic hypotension. RESULTS: Over 15,000 admissions were identified, of which 1192 patients were included, 824 (69%) of whom were prescribed an analgesic medication. Paracetamol (used by 89% of analgesic users), opioids (34%) and adjuvants (17%) were used more frequently than non-steroidal anti-inflammatory drugs (8%). Analgesic users had a higher Drug Burden Index, were prescribed more medications and were less likely to be male compared with non-users. Charlson Comorbidity Index across the cohort was high (7.3 ± 1.9) but there was no difference between analgesic users and non-users, but analgesic users were more likely to have a documented diagnosis of osteoarthritis, osteoporosis and falls. Opioid use was associated with the Drug Burden Index, while adjuvant use was associated with orthostatic hypotension. Opioid use was associated with having a diagnosis of osteoporosis and falls. CONCLUSIONS: In our cohort of poly-medicated elderly patients, prescription of analgesic medications was common, and these patients are likely to have an increased rate of adverse drug reactions and falls compared with those who were not prescribed analgesic medications.
