ABSTRACT
INTRODUCTION: The GOAL Cluster Randomised Controlled Trial (NCT04538157) is now underway, investigating the impact of comprehensive geriatric assessment (CGA) for frail older people with chronic kidney disease (CKD). The primary outcome is the attainment of patient-identified goals at 3 months, assessed using the goal attainment scaling process. The protocol requires a dedicated process evaluation that will occur alongside the main trial, to investigate issues of implementation, mechanisms of impact and contextual factors that may influence intervention success. This process evaluation will offer novel insights into how and why CGA might be beneficial for frail older adults with CKD and provide guidance when considering how to implement this complex intervention into clinical practice. METHODS AND ANALYSIS: This process evaluation protocol follows guidance from the Medical Research Council and published guidance specific for the evaluation of cluster-randomised trials. A mixed methodological approach will be taken using data collected as part of the main trial and data collected specifically for the process evaluation. Recruitment and process data will include site feasibility surveys, screening logs and site issues registers from all sites, and minutes of meetings with intervention and control sites. Redacted CGA letters will be analysed both descriptively and qualitatively. Approximately 60 semistructured interviews will be analysed with a qualitative approach using a reflexive thematic analysis, with both inductive and deductive approaches underpinned by an interpretivist perspective. Qualitative analyses will be reported according to the Consolidated criteria for Reporting Qualitative research guidelines. The Standards for Quality Improvement Reporting Excellence guidelines will also be followed. ETHICS AND DISSEMINATION: Ethics approval has been granted through Metro South Human Research Ethics Committee (HREC/2020/QMS/62883). Dissemination will occur through peer-reviewed journals and feedback to trial participants will be facilitated through the central coordinating centre. TRIAL REGISTRATION NUMBER: NCT04538157.

Frailty may represent a modifiable risk factor for dementia, but the direction of that association remains uncertain. We investigated frailty trajectories in the years preceding dementia onset using data from 23,672 participants (242,760 person-years of follow-up, 2,906 cases of incident dementia) across four cohort studies in the United States and United Kingdom. Bayesian non-linear models revealed accelerations in frailty trajectories 4-9 years before incident dementia. Among participants whose time between frailty measurement and incident dementia exceeded that prodromal period, frailty remained positively associated with dementia risk (adjusted hazard ratios ranged from 1.20 [95% confidence interval, CI = 1.15-1.26] to 1.43 [95% CI = 1.14-1.81]). This observational evidence suggests that frailty increases dementia risk independently of any reverse causality. These findings indicate that frailty measurements can be used to identify high-risk population groups for preferential enrolment into clinical trials for dementia prevention and treatment. Frailty itself may represent a useful upstream target for behavioural and societal approaches to dementia prevention.
ABSTRACT
BACKGROUND: Hospital patients with behavioural and psychological symptoms of dementia (BPSD) are vulnerable to a range of adverse outcomes. Hospital-based Special Care Units (SCUs) are secure dementia-enabling environments providing specialised gerontological care. Due to a scarcity of research, their value remains unconfirmed. OBJECTIVE: To compare hospital based SCU management of BPSD with standard care. DESIGN: Single-case multiple baseline design. SETTING AND PARTICIPANTS: One-hundred admissions to an 8-bed SCU over 2 years in a large Australian public hospital. METHODS: Repeated measures of BPSD severity were undertaken prospectively by specialist dementia nurses for patients admitted to a general ward (standard care) and transferred to the SCU. Demographic and other clinical data, including diagnoses, medication use, and care-related outcomes were obtained from medical records retrospectively. Analysis used multilevel models to regress BPSD scores onto care-setting outcomes, adjusting for time and other factors. RESULTS: When receiving standard care, patients' BPSD severity was 6.8 (95% CI 6.04-7.64) points higher for aggression, 15.6 (95% CI 13.90-17.42) points higher for the neuropsychiatric inventory, and 5.8 (95% CI 5.14-6.50) points higher for non-aggressive agitation compared to SCU. Patients receiving standard care also experienced increased odds for patient-to-nurse violence (OR 2.61, 95% CI 1.67-4.09), security callouts (OR 5.39 95% CI 3.40-8.52), physical restraint (OR 17.20, 95% CI 7.94-37.25) and antipsychotic administration (OR 3.41, 95% CI 1.60-7.24). CONCLUSION: Clinically significant reductions in BPSD and psychotropic administration were associated with SCU care relative to standard ward care. These results suggest more robust investigation of hospital SCUs, and dementia-enabling design are warranted.

BACKGROUND: Preoperative frailty is associated with increased risk of adverse outcomes. In 2017, McIsaac and colleagues' systematic review found that few interventions improved outcomes in this population and evidence was low-quality. We aimed to systematically review the evidence for multicomponent perioperative interventions in frail patients that has emerged since McIsaac et al.'s review. METHODS: PUBMED, EMBASE, Cochrane, and CINAHL databases were searched for English-language studies published since January 1, 2016, that evaluated multicomponent perioperative interventions in patients identified as frail. Quality was assessed using the National Institute of Health Quality Assessment Tool. A narrative synthesis of the extracted data was conducted. RESULTS: Of 2835 articles screened, five studies were included, all of which were conducted in elective oncologic gastrointestinal surgical populations. Four hundred and thirteen patients were included across the five studies and the mean/median age ranged from 70.1 to 87.0 years. Multicomponent interventions were all applied in the preoperative period. Two studies also applied interventions postoperatively. All interventions addressed exercise and nutritional domains with variability in timing, delivery, and adherence. Multicomponent interventions were associated with reduced postoperative complications, functional deterioration, length of stay, and mortality. Four studies reported on patient-centred outcomes. The quality of evidence was fair. CONCLUSIONS: This systematic review provides evidence that frail surgical patients undergoing elective oncologic gastrointestinal surgery may benefit from targeted multicomponent perioperative interventions. Yet methodological issues and substantial heterogeneity of the interventions precludes drawing clear conclusions regarding the optimal model of care. Larger, low risk of bias studies are needed to evaluate optimal intervention delivery, effectiveness in other populations, implementation in health care settings and ascertain outcomes of importance for frail patients and their carers.

OBJECTIVES: To determine the strength and nature of the association between delirium and incident dementia in a population of older adult patients without dementia at baseline. DESIGN: Retrospective cohort study using large scale hospital administrative data. SETTING: Public and private hospitals in New South Wales, Australia between July 2001 and March 2020. PARTICIPANTS: Data were extracted for 650 590 hospital patients aged ≥65 years. Diagnoses of dementia and delirium were identified from ICD-10 (international classification of diseases, 10th revision) codes. Patients with dementia at baseline were excluded. Delirium-no delirium pairs were identified by matching personal and clinical characteristics, and were followed for more than five years. MAIN OUTCOME MEASURES: Cox proportional hazards models and Fine-Gray hazard models were used to estimate the associations of delirium with death and incident dementia, respectively. Delirium-outcome dose-response associations were quantified, all analyses were performed in men and women separately, and sensitivity analyses were conducted. RESULTS: The study included 55 211 matched pairs (48% men, mean age 83.4 years, standard deviation 6.5 years). Collectively, 58% (n=63 929) of patients died and 17% (n=19 117) had a newly reported dementia diagnosis during 5.25 years of follow-up. Patients with delirium had 39% higher risk of death (hazard ratio 1.39, 95% confidence interval 1.37 to 1.41) and three times higher risk of incident dementia (subdistribution hazard ratio 3.00, 95% confidence interval 2.91 to 3.10) than patients without delirium. The association with dementia was stronger in men (P=0.004). Each additional episode of delirium was associated with a 20% increased risk of dementia (subdistribution hazard ratio 1.20, 95% confidence interval 1.18 to 1.23). CONCLUSIONS: The study findings suggest delirium was a strong risk factor for death and incident dementia among older adult patients. The data support a causal interpretation of the association between delirium and dementia. The clinical implications of delirium as a potentially modifiable risk factor for dementia are substantial.

BACKGROUND: Goals generated by Goal Attainment Scaling (GAS) can be used as an outcome measure to promote person-centred research and care. There are no training packages which support its use outside of the rehabilitation discipline. This paper describes the development and evaluation of a training package to support the implementation of GAS as an outcome measure in healthcare research. The training package consisted of classroom teaching, a training manual for self-directed learning, one-on-one simulation and hot reviews. It was developed for the GOAL Trial, a randomised controlled trial assessing a Comprehensive Geriatric Assessment's effectiveness in enabling frail older people living with chronic kidney disease to attain their goals. Training participants were invited to complete pre- and post-training online evaluation surveys. RESULTS: Forty-two healthcare professionals attended an initial online classroom teaching, with 27 proceeding to administer GAS to GOAL Trial patients. Response rates for the online pre- and post-training surveys were 95% and 72%, respectively. Prior to training, only 15% of participants reported being able to appropriately scale and troubleshoot GAS goals. Post-training this was 92%. There was 100% participant satisfaction for the training manual, one-on-one simulation, and hot reviews. CONCLUSIONS: This training package helps ensure healthcare professionals administering GAS have adequate knowledge and skills. It has the potential for adoption as a guide to support the implementation of GAS by other researchers seeking to embrace persont-centred principles in their work.

INTRODUCTION: Frailty is associated with adverse outcomes among patients attending emergency departments (EDs). While multiple frailty screens are available, little is known about which variables are important to incorporate and how best to facilitate accurate, yet prompt ED screening. To understand the core requirements of frailty screening in ED, we conducted an international, modified, electronic two-round Delphi consensus study. METHODS: A two-round electronic Delphi involving 37 participants from 10 countries was undertaken. Statements were generated from a prior systematic review examining frailty screening instruments in ED (logistic, psychometric and clinimetric properties). Reflexive thematic analysis generated a list of 56 statements for Round 1 (August-September 2021). Four main themes identified were: (i) principles of frailty screening, (ii) practicalities and logistics, (iii) frailty domains and (iv) frailty risk factors. RESULTS: In Round 1, 13/56 statements (23%) were accepted. Following feedback, 22 new statements were created and 35 were re-circulated in Round 2 (October 2021). Of these, 19 (54%) were finally accepted. It was agreed that ideal frailty screens should be short (<5 min), multidimensional and well-calibrated across the spectrum of frailty, reflecting baseline status 2-4 weeks before presentation. Screening should ideally be routine, prompt (<4 h after arrival) and completed at first contact in ED. Functional ability, mobility, cognition, medication use and social factors were identified as the most important variables to include. CONCLUSIONS: Although a clear consensus was reached on important requirements of frailty screening in ED, and variables to include in an ideal screen, more research is required to operationalise screening in clinical practice.

BACKGROUND: Developing effective strategies for reducing dementia risk requires a detailed understanding of the risk and protective factors associated with the progression of mild cognitive impairment (MCI) to dementia. OBJECTIVE: We aimed to systematically review the evidence for sex differences in these factors. METHODS: Five online databases (PubMed/CINAHL/EMBASE/PsycINFO/Cochrane) were searched from inception until 17 October 2022 for cohort studies that focused on sex differences in risk and protective factors in the progression of MCI to dementia. RESULTS: A total of 2,972 studies were identified, of which 12 studies from five countries were included in the systematic review. There was substantial variability in study designs, study populations and outcome measures. Sex differences were present in the associations of sociodemographic, health, psychological factors, genetic and other biomarkers with the progression of MCI to dementia. APOE É4 status and depression appeared to increase the risk of progression for females, whereas history of stroke, MRI markers and cerebrospinal fluid biomarkers appeared to increase the risk of progression for males. APOE É2 status and marital status (unmarried) were observed to reduce risk of progression in males and females, respectively. CONCLUSIONS: The ability of studies to accurately detail risk factors for dementia are likely limited when solely controlling for the effects of sex. Although the heterogeneity and underpowered nature of the studies made it difficult to synthesize the findings for each risk factor, this study highlights the apparent need for further research examining risk factors for dementia in males and females with MCI separately.

BACKGROUND: Frailty is prevalent in older people with chronic kidney disease (CKD) and robust evidence supporting the benefit of dialysis in this setting is lacking. We aimed to measure frailty and quality of life (QOL) longitudinally in older people with advanced CKD and assess the impact of dialysis initiation on frailty, QOL and mortality. METHODS: Outpatients aged ≥65 with an eGFR ≤ 20ml/minute/1.73m2 were enrolled in a prospective observational study and followed up four years later. Frailty status was measured using a Frailty Index (FI), and QOL was evaluated using the EuroQol 5D-5L instrument. Mortality and dialysis status were determined through inspection of electronic records. RESULTS: Ninety-eight participants were enrolled. Between enrolment and follow-up, 36% of participants commenced dialysis and 59% died. Frailty prevalence increased from 47% at baseline to 86% at follow-up (change in median FI = 0.22, p < 0.001). Initiating dialysis was not significantly associated with change in FI. QOL declined from baseline to follow-up (mean EQ-5D-5L visual analogue score of 70 vs 63, p = 0.034), though commencing dialysis was associated with less decline in QOL. Each 0.1 increment in baseline FI was associated with 59% increased mortality hazard (HR = 1.59, 95%CI = 1.20 to 2.12, p = 0.001), and commencing dialysis was associated with 59% reduction in mortality hazard (HR = 0.41, 95%CI = 0.20 to 0.87, p = 0.020) irrespective of baseline FI. CONCLUSIONS: Frailty increased substantially over four years, and higher baseline frailty was associated with greater mortality. Commencing dialysis did not affect the trajectory of FI but positively influenced the trajectory of QOL from baseline to follow-up. Within the limitations of small sample size, our data suggests that frail participants received similar survival benefit from dialysis as non-frail participants.

Background: Clinical Practice Guidelines suggest that frailty be measured during kidney transplant eligibility assessments. Yet it is not known how frailty is best assessed in this setting or whether its assessment is acceptable to patients. We aimed to examine the construct validity and feasibility of Frailty Index (FI) assessment among patients attending a kidney transplant assessment clinic and to explore patients' perspectives on frailty and the acceptability of its routine assessment. Methods: A 58-item FI was calculated for 147 clinic patients. Semistructured interviews were conducted with a subgroup of 29 patients. The FI was validated against normative FI characteristics (mean, distribution, limit), age, and the Estimated Post-Transplant Survival Score. Feasibility was assessed using descriptive statistics. Qualitative data were analyzed using reflexive thematic analysis. Results: The mean FI was 0.23 (±0.10, normal distribution, limit 0.53). FI increased with age and Estimated Post-Transplant Survival score. The FI was completed for 62.8% of eligible patients (147/234). The median completion time was 10 min, and completion rate (with no missing data) was 100%. Four themes were identified: perceptions of frailty, acceptability, perceived benefits, and risks of frailty measurement. Patients linked frailty with age and adverse outcomes, and most did not consider themselves frail. Patients reported that the FI was quick, simple, and efficient. They felt that frailty assessment is relevant to transplant eligibility and should be used to address potentially reversible factors. Conclusions: The FI demonstrated construct validity and was feasible and acceptable in this clinic setting. The challenge is ensuring that routine assessments lead to better care.
ABSTRACT
BACKGROUND: Incontinence is common in hospitalised older adults but few studies report new incidence during or following hospitalisation. OBJECTIVE: To describe prevalence and incidence of incontinence in older inpatients and associations with clinical outcomes. DESIGN: Secondary analysis of prospectively collected data from consecutive consenting inpatients age 65 years and older on medical and surgical wards in four Australian public hospitals. METHODS: Participants self-reported urinary and faecal incontinence 2 weeks prior to admission, at hospital discharge and 30 days after discharge as part of comprehensive assessment by a trained research assistant. Outcomes were length of stay, facility discharge, 30-day readmission and 6-month mortality. RESULTS: Analysis included 970 participants (mean age 76.7 years, 48.9% female). Urinary and/or faecal incontinence was self-reported in 310/970 (32.0%, [95% confidence interval (CI) 29.0-35.0]) participants 2 weeks before admission, 201/834 (24.1% [95% CI 21.2-27.2]) at discharge and 193/776 (24.9% [95% CI 21.9-28.1]) 30 days after discharge. Continence patterns were dynamic within the peri-hospital period. Of participants without pre-hospital incontinence, 74/567 (13.1% [95% CI 10.4-16.1) reported incontinence at discharge and 85/537 (15.8% [95% CI 12.8-19.2]) reported incontinence at 30 days follow-up. Median hospital stay was longer in participants with pre-hospital incontinence (7 vs. 6 days, P = 0.02) even in adjusted analyses and pre-hospital incontinence was significantly associated with mortality in unadjusted but not adjusted analyses. CONCLUSION: Pre-hospital, hospital-acquired and new post-hospital incontinence are common in older inpatients. Better understanding of incontinence patterns may help target interventions to reduce this complication.

OBJECTIVE: To examine factors that may influence the risk of discharge to a residential aged care facility (RACF) in a population of frail older inpatients. METHODS: We analysed data from 5846 inpatients aged over 60 years from 27 hospitals in Queensland, Australia, admitted from independent living and referred for geriatric consultation. Patients underwent an interRAI Acute Care Comprehensive Geriatric Assessment by trained nurses. Frailty was assessed using a 52-item frailty index (FI). Risk/protective factors were determined a priori. Logistic regression assessed the relationship between factors and discharge destination, adjusted for FI, age, sex and hospital. Frailty × risk/protective factor interactions were performed. RESULTS: Patients had a mean (SD) age of 79.7 (8.2) years and a mean (SD) FI of 0.44 (0.14). Twenty-nine per cent (n = 1678) of patients were discharged to an RACF. Each 0.1 increment in FI increased the risk of discharge to an RACF by 54% (OR 1.54, 95% CI 1.40-1.68, p < 0.01). Being married or in a de facto relationship had protective effects up to an FI of 0.7, whereas behavioural and psychological symptoms of dementia (BPSD) increased the risk of RACF discharge up to an FI of 0.7. Female sex, faecal incontinence and living alone did not influence the relationship between frailty and discharge destination. CONCLUSIONS: The association between frailty and discharge to RACF has previously been recognised but here we found that risk and protective factors can influence this association. Whether early identification and management of mutable factors can reduce discharge to RACF should be addressed in future studies.

OBJECTIVE(S): To understand Australian health professionals' perceptions of their knowledge and previous training about frailty, as well as barriers to frailty assessment and management in their practice. METHODS: A cross-sectional online survey was developed and distributed to health professionals (medical, nursing and allied health) engaged in clinical practice in Australia through convenience and snowball sampling techniques from March to May 2022. The survey consisted of five sections: frailty training and knowledge; confidence in recognising and managing adults with frailty; the importance and relevance of frailty; barriers to assessing and managing frailty in practice; and interest in further frailty training. Responses were analysed using descriptive statistics. RESULTS: The survey was taken by 736 health professionals. Less than half of respondents (44%, 321/733) reported receiving any training on frailty, with 14% (105/733) receiving training specifically focussed on frailty. Most respondents (78%, 556/712) reported 'good' or 'fair' understanding of frailty. The majority (64%, 448/694) reported being 'fairly' or 'somewhat' confident with identifying frailty. Almost all respondents (>90%) recognised frailty as having an important impact on outcomes and believed that there are beneficial interventions for frailty. Commonly reported barriers to frailty assessment in practice included 'lack of defined protocol for managing frailty' and 'lack of consensus about which frailty assessment tool to use'. Most respondents (88%, 521/595) were interested in receiving further education on frailty, with a high preference for online training. CONCLUSIONS: The findings suggest frailty is important to health professionals in Australia, and there is a need for and interest in further frailty education.
ABSTRACT
OBJECTIVES: Early identification of inpatients at risk of developing delirium and implementing preventive measures could avoid up to 40% of delirium cases. Machine learning (ML)-based prediction models may enable risk stratification and targeted intervention, but establishing their current evolutionary status requires a scoping review of recent literature. METHODS: We searched ten databases up to June 2022 for studies of ML-based delirium prediction models. Eligible criteria comprised: use of at least one ML prediction method in an adult hospital inpatient population; published in English; reporting at least one performance measure (area under receiver-operator curve (AUROC), sensitivity, specificity, positive or negative predictive value). Included models were categorised by their stage of maturation and assessed for performance, utility and user acceptance in clinical practice. RESULTS: Among 921 screened studies, 39 met eligibility criteria. In-silico performance was consistently high (median AUROC: 0.85); however, only six articles (15.4%) reported external validation, revealing degraded performance (median AUROC: 0.75). Three studies (7.7%) of models deployed within clinical workflows reported high accuracy (median AUROC: 0.92) and high user acceptance. DISCUSSION: ML models have potential to identify inpatients at risk of developing delirium before symptom onset. However, few models were externally validated and even fewer underwent prospective evaluation in clinical settings. CONCLUSION: This review confirms a rapidly growing body of research into using ML for predicting delirium risk in hospital settings. Our findings offer insights for both developers and clinicians into strengths and limitations of current ML delirium prediction applications aiming to support but not usurp clinician decision-making.

AIMS: The frailty index (FI) is one way in which frailty can be quantified. While it is measured as a continuous variable, various cut-off points have been used to categorise older adults as frail or non-frail, and these have largely been validated in the acute care or community settings for older adults without cancer. This review aimed to explore which FI categories have been applied to older adults with cancer and to determine why these categories were selected by study authors. METHODS: This scoping review searched Medline, EMBASE, Cochrane, CINAHL, and Web of Science databases for studies which measured and categorised an FI in adults with cancer. Of the 1994 screened, 41 were eligible for inclusion. Data including oncological setting, FI categories, and the references or rationale for categorisation were extracted and analysed. RESULTS: The FI score used to categorise participants as frail ranged from 0.06 to 0.35, with 0.35 being the most frequently used, followed by 0.25 and 0.20. The rationale for FI categories was provided in most studies but was not always relevant. Three of the included studies using an FI > 0.35 to define frailty were frequently referenced as the rationale for subsequent studies, however, the original rationale for this categorisation was unclear. Few studies sought to determine or validate optimum FI categorises in this population. CONCLUSION: There is significant variability in how studies have categorised the FI in older adults with cancer. An FI ≥ 0.35 to categorise frailty was used most frequently, however an FI in this range has often represented at least moderate to severe frailty in other highly-cited studies. These findings contrast with a scoping review of highly-cited studies categorising FI in older adults without cancer, where an FI ≥ 0.25 was most common. Maintaining the FI as a continuous variable is likely to be beneficial until further validation studies determine optimum FI categories in this population. Differences in how the FI has been categorised, and indeed how older adults have been labelled as 'frail', limits our ability to synthesise results and to understand the impact of frailty in cancer care.

OBJECTIVE: To examine the relationship between sublingual microcirculatory measures and frailty index in those attending a kidney transplant assessment clinic. METHODS: Patients recruited had their sublingual microcirculation taken using sidestream dark field videomicroscopy (MicroScan, Micro Vision Medical, Amsterdam, the Netherlands) and their frailty index score using a validated short form via interview. RESULTS: A total of 44 patients were recruited with two being excluded due to microcirculatory image quality scores exceeding 10. The frailty index score indicated significant correlations with total vessel density (p < .0001, r = -.56), microvascular flow index (p = .004, r = -.43), portion of perfused vessels (p = .0004, r = -.52), heterogeneity index (p = .015, r = .32), and perfused vessel density (p < .0001, r = -.66). No correlation was shown between the frailty index and age (p = .08, r = .27). CONCLUSIONS: There is a relationship between the frailty index and microcirculatory health in those attending a kidney transplant assessment clinic, that is not confounded by age. These findings suggest that the impaired microcirculation may be an underlying cause of frailty.

Social frailty refers to an inability to meet basic social needs and has been identified as a threat to physical and mental health. Although social frailty has been linked with many adverse health and well-being outcomes, potential mediators of the relationship between social frailty and well-being remain poorly understood. Emotion regulation refers to the capacity to alter the experience of emotions to behave in accordance with a desired goal. The present study was designed to provide the first direct test of whether emotion regulation mediates the relationships between social frailty and important well-being outcomes (stress, anxiety, and depression). A total of 790 participants completed validated measures of social frailty, stress, anxiety, depression, and emotion regulation. In line with our preregistered hypotheses, higher social frailty predicted increased stress, anxiety, and depression, and each of these relationships were partially mediated by emotion regulation capacity. These data provide novel evidence that emotion regulation abilities may serve as a protective factor against the negative consequences of social frailty.

INTRODUCTION: Individuals with severe mental illness are at risk of becoming prematurely frail. There is a critical unmet need for an intervention that reduces the risk of frailty and minimises the associated negative outcomes in this population. This study aims to provide novel evidence on the feasibility, acceptability and preliminary effectiveness of Comprehensive Geriatric Assessment (CGA) to improve health outcomes among people with co-occurring frailty and severe mental illness. METHODS AND ANALYSIS: Twenty-five participants with frailty and severe mental illness, aged 18-64 years, will be recruited from Metro South Addiction and Mental Health Service outpatient clinics and provided with the CGA. Primary outcome measures will include the feasibility and acceptability of the CGA embedded in routine healthcare. Other variables of interest will include frailty status, quality of life, polypharmacy, and a range of mental and physical health factors. ETHICS AND DISSEMINATION: All procedures involving human subjects/patients were approved by Metro South Human Research Ethics Committee (HREC/2022/QMS/82272). Study findings will be disseminated through peer-reviewed publications and conference presentations.

Frailty, a state of reduced physiological reserve, has not been studied in consumers with treatment-resistant schizophrenia, despite known elevated rates of comorbidity and psychosocial impairment. This study applies a frailty index to the electronic medical records of 78 adults with treatment-resistant schizophrenia, aged 18-64 years, to determine the prevalence and characteristics of frailty (defined as a frailty index score > 0.21). The mean frailty index score was 0.24 (SD = 0.091, range = 0.061-0.54), with 52.6% of the population categorised as frail (40.0% in those aged 18-39 years). Frailty was positively correlated with age and psychiatric illness severity. This study provides novel evidence that individuals with treatment-resistant schizophrenia have a high rate of frailty and become frail at a younger age. Routine frailty assessments could be used to trigger the delivery of appropriate interventions, which have the potential to improve life expectancy and quality of life.
