Interactions between age, sex and visceral adipose tissue on brain ageing.

AIM: To examine the associations between visceral adipose tissue (VAT) and brain structural measures at midlife and explore how these associations may be affected by age, sex and cardiometabolic factors. METHODS: We used abdominal and brain magnetic resonance imaging data from a population-based cohort of people at midlife in the UK Biobank. Regression modelling was applied to study associations of VAT volume with total brain volume (TBV), grey matter volume (GMV), white matter volume, white matter hyperintensity volume (WMHV) and total hippocampal volume (THV), and whether these associations were altered by age, sex or cardiometabolic factors. RESULTS: Complete data were available for 17 377 participants (mean age 63 years, standard deviation = 12, 53% female). Greater VAT was associated with lower TBV, GMV and THV (P < .001). We found an interaction between VAT and sex on TBV (P < .001), such that the negative association of VAT with TBV was greater in men (ß = -2.89, 95% confidence interval [CI] -2.32 to -10.15) than in women (ß = -1.32, 95% CI -0.49 to -3.14), with similar findings for GMV. We also found an interaction between VAT and age (but not sex) on WMHV (P < .001). The addition of other cardiometabolic factors or measures of physical activity resulted in little change to the models. CONCLUSIONS: VAT volume is associated with poorer brain health in midlife and this relationship is greatest in men and those at younger ages.

Healthcare consumer acceptability of routine use of the EQ-5D-5L in clinical care: a cross-sectional survey.

PURPOSE: Patient reported outcome measures, such as the EQ-5D-5L, provide a measure of self-perceived health status or health-related quality of life. Understanding the consumer acceptability of a patient reported outcome measure can help to decide about its implementation across a healthcare organisation and possibly increase the likelihood of its use in clinical care. This study established the acceptability of the EQ-5D-5L from the perspective of clients receiving healthcare, and determined if acceptability varied by client sub-types. METHODS: A cross-sectional survey explored clients' experience of the EQ-5D-5L. Eligible clients were aged ≥ 18 years and completed the EQ-5D-5L on admission and discharge to one of two multi-disciplinary community health services. Likert scale items explored acceptability, and open-ended questions determined if the EQ-5D-5L reflects experience of illness. Associations between acceptability and client characteristics were established using χ2 test. Open-ended questions were analysed using content analysis. RESULTS: Most of the 304 clients (mean age 70 years, SD 16) agreed that the EQ-5D-5L: was easy to use/understand (n = 301, 99%) and useful (n = 289, 95%); improved communication with their therapist (n = 275, 90%); and made them feel more in control of their health (n = 276, 91%). Most clients also agreed that they wished to continue using the EQ-5D-5L (n = 285, 93%). Clients aged ≥ 60 years reported lower acceptability. Clients noted that the EQ-5D-5L did not capture experience of illness related to fatigue, balance/falls, cognition, and sleep. CONCLUSION: The EQ-5D-5L is acceptable for use in care but does not capture all aspects of health relevant to clients, and acceptability varies by subgroup.

The eye of the beholder: how do public health researchers interpret regression coefficients? A qualitative study.

BACKGROUND: Calls for improved statistical literacy and transparency in population health research are widespread, but empirical accounts describing how researchers understand statistical methods are lacking. To address this gap, this study aimed to explore variation in researchers' interpretations and understanding of regression coefficients, and the extent to which these statistics are viewed as straightforward statements about health. METHODS: Thematic analysis of qualitative data from 45 one-to-one interviews with academics from eight countries, representing 12 disciplines. Three concepts from the sociology of scientific knowledge and science studies aided analysis: Duhem's Paradox, the Agonistic Field, and Mechanical Objectivity. RESULTS: Some interviewees viewed regression as a process of discovering 'real' relationships, while others indicated that regression models are not direct representations, and others blended these perspectives. Regression coefficients were generally not viewed as being mechanically objective, instead interpretation was described as iterative, nuanced, and sometimes depending on prior understandings. Researchers reported considering numerous factors when interpreting and evaluating regression results, including: knowledge from outside the model, whether results are expected or unexpected, 'common-sense', technical limitations, study design, the influence of the researcher, the research question, data quality and data availability. Interviewees repeatedly highlighted the role of the analyst, reinforcing that it is researchers who answer questions and assign meaning, not models. CONCLUSIONS: Regression coefficients were generally not viewed as complete or authoritative statements about health. This contrasts with teaching materials wherein statistical results are presented as straightforward representations, subject to rule-based interpretations. In practice, it appears that regression coefficients are not understood as mechanically objective. Attempts to influence conduct and presentation of regression models in the population health sciences should be attuned to the myriad factors which inform their interpretation.

Symptoms of depression and risk of emergency department visits among people aged 70 years and over.

BACKGROUND: Older people experiencing depression and anxiety have higher rates of health service utilisation than others, but little is known about whether these influence their seeking of emergency care. The aim was to examine the associations between symptoms of depression and the use of emergency health care, in an Australian context, among a population of people aged 70 years and over initially free of cardiovascular disease, dementia or major physical disability. METHODS: We undertook secondary analyses of data from a large cohort of community-dwelling Australians aged [Formula: see text]70 years. Multivariable logistic regression was used to compare the association of symptoms of depression (measured using the Center for Epidemiological Studies Depression Scale 10 question version, CESD at baseline) with subsequent episodes of emergency care, adjusting for physical and social factors of clinical interest. Marginal adjusted odds ratios were calculated from the logistic regression. RESULTS: Data were available for 10,837 Australian participants aged at least 70 years. In a follow-up assessment three years after the baseline assessment, 17.6% of people self-reported an episode of emergency care (attended an ED of called an emergency ambulance) in the last 12 months. Use of emergency healthcare was similar for men and women (17.8% vs. 17.4% p = 0.61). A score above the cut-off on the CESD at baseline was associated with greater use of emergency health care (OR = 1.35, 95% CI 1.11,1.64). When modelled separately, there was a greater association between a score above the cut-off on the CESD and emergency healthcare for women compared with men. CONCLUSIONS: This study is unique in demonstrating how depressive symptoms among healthy older persons are associated with subsequent increased use of emergency healthcare. Improved understanding and monitoring of mental health in primary care is essential to undertake effective healthcare planning including prevention of needing emergency care.

Benralizumab and mepolizumab treatment outcomes in two severe asthma clinics.

BACKGROUND AND OBJECTIVE: This study compared the clinical outcomes of severe asthmatics treated with mepolizumab and benralizumab in a tertiary care severe asthma service setting. METHODS: Patient data at baseline, six and 12 months were collected prospectively at two large tertiary hospital severe asthma clinics following treatment initiation. Two hundred and four patients received treatment with mepolizumab (117) or benralizumab (87). Baseline characteristics between groups were similar in regard to age, gender, body mass index, steroid dose and blood eosinophil count. However, the mepolizumab cohort had a higher Asthma Control Questionnaire Score (ACQ) at baseline (4.0 ± 1.1 vs. 3.6 ± 0.9, p = 0.018), accompanied by more frequent reliever medication usage and lower prebronchodilator FEV1 % (56.0 ± 20.1 vs. 63.8 ± 18.9, p = 0.008). RESULTS: After 6 months treatment, both treatments induced significant improvements in (i) ACQ of 2.3 ± 0.1 (p < 0.001), (ii) oral steroid requiring exacerbations (incident rate ratio 0.26 (0.18-0.37), p < 0.001) and (iii) FEV1 . However, the improvement in FEV1 was 0.18 (0.05-0.30) litres greater with benralizumab than with mepolizumab (p = 0.002) even when adjusting statistically for baseline differences between groups. These differences were even more pronounced at 12 months post-treatment initiation, when the improvement in exacerbation frequency with benralizumab was 64% greater than with mepolizumab (p = 0.01). Whilst both treatments significantly reduced the blood eosinophil count at 6 and 12 months, this reduction was substantially greater with benralizumab than mepolizumab (-260 cells/µL [-400 to -110, p = 0.001]). CONCLUSION: In this large group of severe eosinophilic asthmatics, mepolizumab and benralizumab both improved disease parameters. However, benralizumab treatment appeared significantly more effective than mepolizumab in reducing exacerbations, improving FEV1 and depleting blood eosinophils.

The Role of Daily Step Count in Determining Risk Factors for Falls.

Falls risk is often assessed without considering exposure to risk. We examined the risk factors associated with falls in those with greater and lower levels of daily step count. Falls were recorded over 12 months using bimonthly calendars in community-dwelling older people (mean age 72.0, SD 6.9). Daily step count was measured using a pedometer worn consecutively for 7 days. A cut score of <5,575.5 steps/day was used to identify people with lower step count. Negative binominal models were used to identify cognitive, medical, and sensorimotor factors associated with falls in those with higher versus lower levels of daily step count. In those with lower daily step count, poorer executive function, slower gait speed, and lower steps per day were associated with increased falls risk. In those with higher step count, only mood was associated with increased falls risk. Considering daily step count is important when assessing falls risk in older people.

Stroke and emergency department re-presentation after outpatient TIA management: An interrupted time series study.

OBJECTIVES: To assess the effects of a non-admitted management pathway following emergency department (ED) presentation with suspected TIA on: 90-day stroke and ED re-presentations, overnight admission, length of stay (LOS) and costs. METHODS: We implemented a management pathway across an Australian regional health service (4 hospitals; 2 rural, 10,000 km2) including ED protocols followed by urgent outpatient review or telemedicine consultation to one rural hospital. Interrupted time series analysis was conducted on linked hospital administrative datasets for all ED TIA diagnoses 5 years before and 2 years after intervention (2015). We assessed whether pathway introduction was associated with immediate change (level) or subsequent rate of change (slope) in outcomes. RESULTS: There were 2031 presentations: 1,467 before, 564 after implementation. Against background declining trends, overnight admissions decreased by 12.4% (95%CI 5.0, 19.7) and total LOS decreased 6 hours (95%CI 1.5, 10.4). Hospital costs reduced by AUD683 per patient with implementation. Outpatient review occurred for 36% at median 5 days (IQR 3, 9), including 19/87 (22%) telemedicine reviews. Pathway adherence was incomplete: 29% had no specialist review. Recurrent stroke increased by 1.3/100 presentations (95%CI 0.6, 2.1) with implementation, then returned to baseline of 0.9/100. ED re-presentations rose at a significant rate after implementation (extra 1.69/100 patients re-presenting/quarter; 95%CI 0.8, 2.6) reaching 32/100. CONCLUSIONS: An ED TIA management pathway designed to avoid hospital admission resulted in decreased hospital use and costs; but an initial increase in recurrent stroke and sustained rise in ED re-presentation, possibly related to delayed and incomplete follow-up.

Association between frailty and clinical outcomes in hospitalised patients requiring Code Blue activation.

BACKGROUND: Code Blues allow a rapid, hospital wide response to acutely deteriorating patients. The concept of frailty is being increasingly recognised as an important element in determining outcomes of critically ill patients. We hypothesised that increasing frailty would be associated with worse outcomes following a Code Blue. AIMS: To investigate the association between increasing frailty and outcomes of Code Blues. METHODS: Single-centre retrospective design of patients admitted to Frankston Hospital in Australia between 1 January 2013 and 31 December 2017 who triggered a Code Blue. Frailty evaluation was made based on electronic medical records as were the details and the outcomes of the Code Blue. The primary outcome measure was a composite of hospital mortality or Cerebral Performance Categories scale ≥3. Secondary outcomes included the immediate outcome of the Code Blue and hospital mortality. RESULTS: One hundred and forty-eight of 911 screened patients were included in the final analysis. Seventy-three were deemed 'frail' and the remainder deemed 'fit'. Seventy-eight percent of frail patients reached the primary outcome, compared with 41% of fit patients (P < 0.001). Multivariable analysis demonstrated frailty to be associated with primary outcome (odds ratio = 2.87; 95% confidence interval (CI) 1.28-6.44; P = 0.01). A cardiac aetiology for the Code Blue was also associated with an increased odds of primary outcome (OR = 3.52; 95% CI 1.51-8.05; P = 0.004). CONCLUSIONS: Frailty is independently associated with the composite outcome of hospital mortality or severe disability following a Code Blue. Frailty is an important tool in prognostication for these patients and might aid in discussions regarding treatment limitations.

Delegation of patient related tasks to allied health assistants: a time motion study.

BACKGROUND: Allied health assistants (AHAs) are support staff who complete patient and non-patient related tasks under the delegation of an allied health professional. Delegating patient related tasks to AHAs can benefit patients and allied health professionals. However, it is unclear whether the AHA workforce is utilised optimally in the provision of patient care. The purpose of this study was to determine the proportion of time AHAs spend on patient related tasks during their working day and any differences across level of AHA experience, clinical setting, and profession delegating the task. METHODS: A time motion study was conducted using a self-report, task predominance work sampling method. AHAs were recruited from four publicly-funded health organisations in Victoria, Australia. AHAs worked with dietitians, occupational therapists, physiotherapists, podiatrists, social workers, speech pathologists, psychologists, and exercise physiologists. The primary outcome was quantity of time spent by AHAs on individual task-categories. Tasks were grouped into two main categories: patient or non-patient related activities. Data were collected from July 2020 to May 2021 using an activity capture proforma specifically designed for this study. Logistic mixed-models were used to investigate the extent to which level of experience, setting, and delegating profession were associated with time spent on patient related tasks. RESULTS: Data from 51 AHAs showed that AHAs spent more time on patient related tasks (293 min/day, 64%) than non-patient related tasks (167 min/day, 36%). Time spent in community settings had lower odds of being delegated to patient related tasks than time in the acute hospital setting (OR 0.44, 95%CI 0.28 to 0.69, P < 0.001). Time delegated by exercise physiologists and dietitians was more likely to involve patient related tasks than time delegated by physiotherapists (exercise physiology: OR 3.77, 95% 1.90 to 7.70, P < 0.001; dietetics: OR 2.60, 95%CI 1.40 to 1.90, P = 0.003). Time delegated by other professions (e.g. podiatry, psychology) had lower odds of involving patient related tasks than physiotherapy (OR 0.37, 95%CI 0.16 to 0.85, P = 0.02). CONCLUSION: AHAs may be underutilised in community settings, and by podiatrists and psychologists. These areas may be targeted to understand appropriateness of task delegation to optimise AHAs' role in providing patient care.

A Cohort Study of Anticholinergic Medication Burden and Incident Dementia and Stroke in Older Adults.

BACKGROUND: Anticholinergic medications may increase risk of dementia and stroke, but prospective studies in healthy older people are lacking. OBJECTIVE: Compare risk of incident dementia and stroke by anticholinergic burden among initially healthy older people. DESIGN: Prospective cohort study. SETTING: Primary care (Australia and USA). PARTICIPANTS: 19,114 community-dwelling participants recruited for the ASPREE trial, aged 70+ years (65+ if US minorities) without major cardiovascular disease, dementia diagnosis, or Modified Mini-Mental State Examination score below 78/100. MEASUREMENTS: Baseline anticholinergic exposure was calculated using the Anticholinergic Cognitive Burden (ACB) score. Dementia was adjudicated using Diagnostic and Statistical Manual of Mental Disorders volume IV criteria, and stroke using the World Health Organization definition. RESULTS: At baseline, 15,000 participants (79%) had an ACB score of zero, 2930 (15%) a score of 1-2, and 1184 (6%) a score of ≥ 3 (indicating higher burden). After a median follow-up of 4.7 years and adjusting for baseline covariates, a baseline ACB score of ≥ 3 was associated with increased risk of ischemic stroke (adjusted HR 1.58, 95% CI 1.06, 2.35), or dementia (adjusted HR 1.36, 95% CI 1.01, 1.82), especially of mixed etiology (adjusted HR 1.53, 95% CI 1.06, 2.21). Results were similar for those exposed to moderate/highly anticholinergic medications. LIMITATIONS: Residual confounding and reverse causality are possible. Assessment of dose or duration was not possible. CONCLUSIONS: High anticholinergic burden in initially healthy older people was associated with increased risk of incident dementia and ischemic stroke. A vascular effect may underlie this association. These findings highlight the importance of minimizing anticholinergic exposure in healthy older people.

Recruiting general practice patients for large clinical trials: lessons from the Aspirin in Reducing Events in the Elderly (ASPREE) study.

OBJECTIVE: To assess the factors that contributed to the successful completion of recruitment for the largest clinical trial ever conducted in Australia, the Aspirin in Reducing Events in the Elderly (ASPREE) study. DESIGN: Enrolment of GPs; identification of potential participants in general practice databases; screening of participants. SETTING, PARTICIPANTS: Selected general practices across southeast Australia (Tasmania, Victoria, Australian Capital Territory, New South Wales, South Australia). MAJOR OUTCOMES: Numbers of patients per GP screened and randomised to participation; geographic and demographic factors that influenced screening and randomising of patients. RESULTS: 2717 of 5833 GPs approached (47%) enrolled to recruit patients for the study; 2053 (76%) recruited at least one randomised participant. The highest randomised participant rate per GP was for Tasmania (median, 5; IQR, 1-11), driven by the high rate of participant inclusion at phone screening. GPs in inner regional (adjusted odds ratio [aOR], 1.45; 95% CI, 1.14-1.84) and outer regional areas (aOR, 1.86; 95% CI, 1.19-2.88) were more likely than GPs in major cities to recruit at least one randomised participant. GPs in areas with a high proportion of people aged 70 years or more were more likely to randomise at least one participant (per percentage point increase: aOR, 1.10; 95% CI, 1.05-1.15). The number of randomised patients declined with time from GP enrolment to first randomisation. CONCLUSION: General practice can be a rich environment for research when barriers to recruitment are overcome. Including regional GPs and focusing efforts in areas with the highest proportions of potentially eligible participants improves recruitment. The success of ASPREE attests to the clinical importance of its research question for Australian GPs.

Three Metaphors to Aid Interdisciplinary Dialogue in Public Health.

Within this journal, authors have recently called for or discussed the benefits of interdisciplinary collaboration. However, in practice such collaborations are extremely challenging, and little guidance is available to support researchers' efforts to communicate with colleagues from other disciplines. This article presents three metaphors from the sociology of scientific knowledge that can inform and support consideration and discussion of disciplinary issues. Disciplinary training acts as a "flashlight," highlighting certain features of reality and leaving others in shadow. Our disciplinary sense of normal science is the metaphorical "box" into which we hope nature will fit, determining the manner in which we advance the frontier by recognizing the familiar in the unfamiliar. Finally, scientific training is a "lens" through which the world is perceived and understood. In interdisciplinary and some multidisciplinary contexts, researchers are encouraged to (1) identify the set of fundamental concepts underpinning their approach to public health, (2) discuss methodological choices in terms that do not depend on familiarity with a common tradition of research excellence, and (3) maintain awareness that colleagues from other fields potentially hold different understandings of key public health concepts.

Accuracy of transcutaneous bilirubinometry in term infants after phototherapy: a prospective observational study.

OBJECTIVE: To test the accuracy of transcutaneous bilirubinometry (TcB) in neonates 12 h after discontinuing phototherapy. STUDY DESIGN: In a prospective study of 91 neonates at ≥35 weeks of gestation, paired measurements of total serum bilirubin (TSB) and TcB were obtained 12 h after discontinuation of phototherapy. TcB measurements were obtained on the uncovered skin of the sternum and the covered skin of the lower abdomen. Bland-Altman plots were used to evaluate agreement between TSB and TcB. RESULTS: TcB was found to systematically underestimate TSB on both covered and uncovered skin. The smallest but statistically significant difference between TSB and TcB was found on the covered lower abdomen (-1.03, p < .0001) compared with the uncovered skin of the sternum (-1.44, p < .0001). The correlation between TSB and TcB was excellent on both covered (r = 0.86, p < .001) and uncovered skin (r = 0.90, p < .001). Bland and Altman plots showed poor agreement between TcB and TSB. CONCLUSIONS: This study demonstrated excellent correlation between TcB and TSB 12 h after phototherapy but poor TcB-TSB agreement. TcB cannot be reliably used in neonates exposed to phototherapy.

Interactive clinical supervision training added to self-education leads to small improvements in the effectiveness of clinical supervision of physiotherapists: a randomised trial.

QUESTION: Does adding an interactive clinical supervision training program to self-education improve the effectiveness of clinical supervision of physiotherapists, reduce burnout, decrease intention to leave and increase participation in clinical supervision? DESIGN: Randomised controlled trial with concealed allocation, assessor blinding and intention-to-treat analysis. PARTICIPANTS: Physiotherapists (n = 58) working at a publicly funded health service. INTERVENTION: Participants in both groups received a self-education clinical supervision training package. In addition, participants in the experimental group received interactive clinical supervision training consisting of three 90-minute workshops. OUTCOME MEASURES: The primary outcome measure was effectiveness of clinical supervision 4 months after training measured using the Manchester Clinical Supervision Scale (MCSS-26). Secondary outcomes were the Maslach Burnout Inventory, the Intention to Leave Scale, and participation in supervision. Focus groups were also used to gauge impressions of the intervention. RESULTS: The addition of interactive clinical supervision training slightly improved effectiveness of clinical supervision, with a between-group mean difference of 6.3 units (95% CI 0.3 to 12.3) on the MCSS-26. The estimate of the effect on the proportion of physiotherapists reporting effective clinical supervision (ie, MSCC-26 score ≥ 73) was unclear (OR 1.97, 95% CI 0.50 to 7.81). Physiotherapists in the experimental group reported slightly lower levels of depersonalisation (MD -3.0 units, 95% CI -4.6 to -1.3). There were negligible or uncertain effects on the other burnout domains, intention to leave and participation in clinical supervision. Qualitatively, participants reported that the workshops made them realise that supervisees could take greater ownership of where supervision focused. CONCLUSION: Adding interactive clinical supervision training to self-education leads to small improvements in the effectiveness of clinical supervision of physiotherapists.

Consumer perspectives of allied health involvement in a public hospital setting: cross-sectional survey and electronic health record review.

Objective Consumer-centred care is fundamental to high-quality health care, with allied health professionals playing a pivotal role in hospital settings. Allied health typically operates within standard weekday working-hours. Consumer preferences for receiving allied health services are largely unexplored but could inform whether weekend and/or out-of-hours services are required. This study aims to understand consumer preferences for hospital-based inpatient and outpatient allied health services. Methods Using a cross-sectional survey and convenience sampling approach, consumers of a public health service in Melbourne, Australia were surveyed about preferences for allied health service delivery. Electronic health record reviews compared the accuracy of self-reported service delivery times. Descriptive statistics, concordance and predictive values were calculated. Responses to free-text survey items were analysed using content analysis. Results Of 120 participants (79% response rate), most (69%) received allied health services, however, almost half of inpatient responders (44%) were unsure of the specific allied health professional involved. Audit results found moderate-high concordance overall (range, 77-96%) between self-reported and audit-identified allied health services by profession. Most inpatient responders had no strong day of week preference, equally selecting weekdays and weekend days, with most preferring services between 8 am and 4 pm. Outpatient responders (81%) preferred a weekday appointment between 8 am and 12 pm or before 8 am (29%) to complete scheduled activities early in the day. Conclusion While provision of allied health services during standard working-hours was preferred by most consumers, some inpatient and outpatient consumers are receptive to receiving weekend and out-of-hours services, respectively. Decisions about offering these services should consider operational capacity and research evidence.

Allied health assistant management of people with hip fracture is feasible and may improve patient adherence to hip fracture mobilisation guidelines: a feasibility randomised controlled trial.

OBJECTIVES: Determine the feasibility of allied health assistant (AHA) management of people with hip fracture an acute hospital. DESIGN: Assessor-blind, parallel, feasibility randomised controlled trial with qualitative component. SETTING: Acute orthopaedic ward. PARTICIPANTS: People with surgically-managed hip fracture, who walked independently pre-fracture and had no cognitive impairment. INTERVENTIONS: Rehabilitation from an AHA, under the supervision of a physiotherapist, compared with rehabilitation from a physiotherapist. MAIN OUTCOME MEASURES: Feasibility was evaluated according to focus areas of demand, acceptability, practicality and implementation. Secondary outcomes included estimates of effect of adherence to hip fracture mobilisation guidelines, discharge destination, 30-day readmission, functional activity, and length of stay. RESULTS: Fifty people were allocated to receive rehabilitation from an AHA (n = 25) or physiotherapist (n = 25). AHA rehabilitation had high demand with 60% of eligible participants recruited. Satisfaction with AHA rehabilitation was comparable with physiotherapy rehabilitation (acceptability). The AHA group received an average of 11 min (95% CI 4 to 19) more therapy per day than the physiotherapy group (implementation). The AHA group may have had lower cost of acute care (MD -$3 808 95% CI -7 651 to 35) and adverse events were comparable between groups (practicality). The AHA group may have been 22% (HR 1.22, 95% CI 0.92 to 1.61) more likely to walk on any day and may have had a shorter length of stay (MD -0.8 days, 95% CI -2.3 to 0.7). CONCLUSIONS: AHA management of patients with hip fracture was feasible and may improve adherence to mobilisation guidelines and reduce cost of care and length of stay.

Staying Active with Multimorbidity In Acute hospital settings (StAMInA) trial: protocol for a feasibility randomised controlled trial of allied health assistant mobility rehabilitation for patients with multimorbidity.

INTRODUCTION: Key to improving outcomes for patients with multimorbidity is increasing mobility through prescription of a physical activity programme, but this can be difficult to achieve in acute hospital settings. One approach that would assist physiotherapists to increase levels of physical activity is delegation of rehabilitation to allied health assistants. We aim to conduct a randomised controlled trial to determine the feasibility of an allied health assistant providing daily inpatient mobility rehabilitation for patients with multimorbidity. METHODS AND ANALYSIS: Using a parallel group randomised controlled design, participants will be allocated to allied health assistant mobility rehabilitation or physiotherapist mobility rehabilitation. Adult inpatients (n=60) in an acute hospital with a diagnosis of multimorbidity who walked independently preadmission will be included. The experimental group will receive routine mobility rehabilitation, including daily mobilisation, from an allied health assistant under the supervision of a physiotherapist. The comparison group will receive routine rehabilitation from a physiotherapist. Feasibility will be determined using the following areas of focus in Bowen's feasibility framework: Acceptability (patient satisfaction); demand (proportion of patients who participate); implementation (time allied health assistant/physiotherapist spends with participant, occasions of service); and practicality (cost, adverse events). Staff involved in the implementation of allied health assistant rehabilitation will be interviewed to explore their perspectives on feasibility. Secondary outcomes include: Physical activity (daily time spent walking); daily mobilisation (Y/N); discharge destination; hospital readmission; falls; functional activity (Modified Iowa Level of Assistance Scale); and length of stay. Descriptive statistics will be used to describe feasibility. Secondary outcomes will be compared between groups using Poisson or negative binomial regression, Cox proportional hazards regression, survival analysis, linear regression or logistic regression. ETHICS AND DISSEMINATION: Ethics approval was obtained from Peninsula Health (HREC/97 431/PH-2023). Findings will be disseminated in peer-reviewed journals and conference presentations.

Impact of pay-for-performance for stroke unit access on mortality in Queensland, Australia: an interrupted time series analysis.

Background: Stroke unit care provides substantial benefits for all subgroups of patient with stroke, but consistent access has been difficult to achieve in many healthcare systems. Pay-for-performance incentives have been introduced widely in attempt to improve quality and efficiency in healthcare, but there is limited evidence of positive impact when they are targeted at hospitals. In 2012, a pay-for-performance program targeting stroke unit access was co-designed and implemented within a clinical quality improvement network across public hospitals in Queensland, Australia. We assessed the impact on access to specialist care and mortality following stroke. Methods: We used interrupted time series analysis on linked hospital and death registry data to compare changes in level (absolute proportions) and trends in outcomes (stroke/coronary care unit admission, 6-month mortality) for stroke, and a control condition of myocardial infarction (MI) without pay-for-performance incentive, from 2009 before, to 2017 after introduction of the pay-for-performance scheme in 2012. Findings: We included 23,572 patients with stroke and 39,511 with MI. Following pay-for-performance introduction, stroke unit access increased by an absolute 35% (95% CI 29, 41) more than historical trend prediction, with greater impact for regional/rural residents (41% vs major city 24%) where baseline access was lowest (18% vs major city residents 53%). Historical upward 6-month mortality trends following stroke (+0.11%/month) reversed to a downward slope (-0.05%/month) with pay-for-performance; difference -0.16%/month (95% CI -0.29, -0.03). In contrast, access to coronary care and mortality trends for MI controls were unchanged, difference-in-difference for mortality -0.18%, (95% CI -0.34, -0.02). Interpretation: This clinician led pay-for-performance incentive stimulated significant improvements in stroke unit access, reduced regional disparities; and resulted in a sustained decline in 6-month mortality. As our findings contrast with lack of effect in most hospital directed pay-for-performance programs, differences in design and context provide insights for optimal program design.

Potentially inappropriate medication use is associated with increased risk of incident disability in healthy older adults.

BACKGROUND: Efforts to minimize medication risks among older adults include avoidance of potentially inappropriate medications (PIMs). However, most PIMs research has focused on older people in aged or inpatient care, creating an evidence gap for community-dwelling older adults. To address this gap, we investigated the impact of PIMs use in the ASPirin in Reducing Events in the Elderly (ASPREE) clinical trial cohort. METHODS: Analysis included 19,114 community-dwelling ASPREE participants aged 70+ years (65+ if US minorities) without major cardiovascular disease, cognitive impairment, or significant physical disability. PIMs were defined according to a modified 2019 AGS Beers Criteria. Cox proportional-hazards regression models were used to estimate the association between baseline PIMs exposure and disability-free survival, death, incident dementia, disability, and hospitalization, with adjustment for sex, age, country, years of education, frailty, average gait speed, and comorbidities. RESULTS: At baseline, 7396 (39% of the total) participants were prescribed at least one PIM. Compared with those unexposed, participants on a PIM at baseline were at an increased risk of persistent physical disability (adjusted hazard ratio [HR] 1.47, 95% confidence interval [CI] 1.21, 1.80) and hospitalization (adjusted HR 1.26, 95% CI 1.20, 1.32), but had similar rates of disability-free survival (adjusted HR 1.02; 95% CI 0.93, 1.13) and death (adjusted HR 0.92, 95% CI 0.81, 1.05). These effects did not vary by polypharmacy status in interaction analyses. PIMs exposure was associated with higher risk of disability followed by hospitalization (adjusted HR 1.92, 95% CI 1.25, 2.96) as well as vice versa (adjusted HR 1.54, 95% CI 1.15, 2.05). PPIs, anti-psychotics and benzodiazepines, were associated with increased risk of disability. CONCLUSIONS: PIMs exposure is associated with subsequent increased risk of both incident disability and hospitalization. Increased risk of disability prior to hospitalization suggests that PIMs use may start the disability cascade in healthy older adults. Our findings emphasize the importance of caution when prescribing PIMs to older adults in otherwise good health.

Association of Dual Decline in Cognition and Gait Speed With Risk of Dementia in Older Adults.

Importance: Dual decline in gait speed and cognition has been found to be associated with increased dementia risk in previous studies. However, it is unclear if risks are conferred by a decline in domain-specific cognition and gait. Objective: To examine associations between dual decline in gait speed and cognition (ie, global, memory, processing speed, and verbal fluency) with risk of dementia. Design, Setting, and Participants: This cohort study used data from older adults in Australia and the US who participated in a randomized clinical trial testing low-dose aspirin between 2010 and 2017. Eligible participants in the original trial were aged 70 years or older, or 65 years or older for US participants identifying as African American or Hispanic. Data analysis was performed between October 2020 and November 2021. Exposures: Gait speed, measured at 0, 2, 4, and 6 years and trial close-out in 2017. Cognitive measures included Modified Mini-Mental State examination (3MS) for global cognition, Hopkins Verbal Learning Test-Revised (HVLT-R) for memory, Symbol Digit Modalities (SDMT) for processing speed, and Controlled Oral Word Association Test (COWAT-F) for verbal fluency, assessed at years 0, 1, 3, 5, and close-out. Participants were classified into 4 groups: dual decline in gait and cognition, gait decline only, cognitive decline only, and nondecliners. Cognitive decline was defined as membership of the lowest tertile of annual change. Gait decline was defined as a decline in gait speed of 0.05 m/s or greater per year across the study. Main Outcomes and Measures: Dementia (using Diagnostic and Statistical Manual of Mental Disorders [Fourth Edition] criteria) was adjudicated by an expert panel using cognitive tests, functional status, and clinical records. Cox proportional hazard models were used to estimate risk of dementia adjusting for covariates, with death as competing risk. Results: Of 19 114 randomized participants, 16 855 (88.2%) had longitudinal gait and cognitive data for inclusion in this study (mean [SD] age, 75.0 [4.4] years; 9435 women [56.0%], 7558 participants [44.8%] with 12 or more years of education). Compared with nondecliners, risk of dementia was highest in the gait plus HVLT-R decliners (hazard ratio [HR], 24.7; 95% CI, 16.3-37.3), followed by the gait plus 3MS (HR, 22.2; 95% CI, 15.0-32.9), gait plus COWAT-F (HR, 4.7; 95% CI, 3.5-6.3), and gait plus SDMT (HR, 4.3; 95% CI, 3.2-5.8) groups. Dual decliners had a higher risk of dementia than those with either gait or cognitive decline alone for 3MS and HVLT-R. Conclusions and Relevance: Of domains examined, the combination of decline in gait speed with memory had the strongest association with dementia risk. These findings support the inclusion of gait speed in dementia risk screening assessments.
