PREhabilitation of CAndidates for REnal Transplantation (PreCareTx) study: protocol for a hybrid type I, mixed method, randomised controlled trial.

INTRODUCTION: Kidney transplant candidates (KTCs) need to be in optimal physical and psychological condition prior to surgery. However, KTCs often experience compromised functional capacity which can be characterised as frailty. Prehabilitation, the enhancement of a person's functional capacity, may be an effective intervention to improve the health status of KTCs. The PREhabilitation of CAndidates for REnal Transplantation (PreCareTx) study aims to examine the effectiveness of a multimodal prehabilitation programme on the health status of KTCs, and to explore the potential of implementation of prehabilitation in daily clinical practice. METHODS AND ANALYSIS: This study uses a single centre, effectiveness-implementation hybrid type I study design, comprised of a randomised controlled trial and a mixed-methods study. Adult patients who are currently on the transplant waiting list or are waitlisted during the study period, at a university medical centre in The Netherlands, will be randomly assigned to either prehabilitation (n=64) or care as usual (n=64) groups. The prehabilitation group will undergo a 12-week home-based, tailored prehabilitation programme consisting of physical and/or nutritional and/or psychosocial interventions depending on the participant's deficits. This programme will be followed by a 12-week maintenance programme in order to enhance the incorporation of the interventions into daily life. The primary endpoint of this study is a change in frailty status as a proxy for health status. Secondary endpoints include changes in physical fitness, nutritional status, psychological well-being, quality of life and clinical outcomes. Tertiary endpoints include the safety, feasibility and acceptability of the prehabilitation programme, and the barriers and facilitators for further implementation. ETHICS AND DISSEMINATION: Medical ethical approval was granted by the Medical Ethics Committee Groningen, Netherlands (M22.421). Written informed consent will be obtained from all participants. The results will be disseminated at international conferences and in peer-reviewed journals. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov, NCT05489432.

Prehabilitation in elective patients undergoing cardiac surgery: a randomised control trial (THE PrEPS TRIAL) - a study protocol.

INTRODUCTION: Prehabilitation prior to surgery has been shown to reduce postoperative complications, reduce length of hospital stay and improve quality of life after cancer and limb reconstruction surgery. However, there are minimal data on the impact of prehabilitation in patients undergoing cardiac surgery, despite the fact these patients are generally older and have more comorbidities and frailty. This trial will assess the feasibility and impact of a prehabilitation intervention consisting of exercise and inspiratory muscle training on preoperative functional exercise capacity in adult patients awaiting elective cardiac surgery, and determine any impact on clinical outcomes after surgery. METHODS AND ANALYSIS: PrEPS is a randomised controlled single-centre trial recruiting 180 participants undergoing elective cardiac surgery. Participants will be randomised in a 1:1 ratio to standard presurgical care or standard care plus a prehabilitation intervention. The primary outcome will be change in functional exercise capacity measured as change in the 6 min walk test distance from baseline. Secondary outcomes will evaluate the impact of prehabilitation on preoperative and postoperative outcomes including; respiratory function, health-related quality of life, anxiety and depression, frailty, and postoperative complications and resource use. This trial will evaluate if a prehabilitation intervention can improve preoperative physical function, inspiratory muscle function, frailty and quality of life prior to surgery in elective patients awaiting cardiac surgery, and impact postoperative outcomes. ETHICS AND DISSEMINATION: A favourable opinion was given by the Sheffield Research Ethics Committee in 2019. Trial findings will be disseminated to patients, clinicians, commissioning groups and through peer-reviewed publication. TRIAL REGISTRATION NUMBER: ISRCTN13860094.

PREPARE trial: a protocol for a multicentre randomised trial of frailty-focused preoperative exercise to decrease postoperative complication rates and disability scores.

INTRODUCTION: Frailty is a strong predictor of adverse postoperative outcomes. Prehabilitation may improve outcomes after surgery for older people with frailty by addressing physical and physiologic deficits. The objective of this trial is to evaluate the efficacy of home-based multimodal prehabilitation in decreasing patient-reported disability and postoperative complications in older people with frailty having major surgery. METHODS AND ANALYSIS: We will conduct a multicentre, randomised controlled trial of home-based prehabilitation versus standard care among consenting patients >60 years with frailty (Clinical Frailty Scale>4) having elective inpatient major non-cardiac, non-neurologic or non-orthopaedic surgery. Patients will be partially blinded; clinicians and outcome assessors will be fully blinded. The intervention consists of >3 weeks of prehabilitation (exercise (strength, aerobic and stretching) and nutrition (advice and protein supplementation)). The study has two primary outcomes: in-hospital complications and patient-reported disability 30 days after surgery. Secondary outcomes include survival, lower limb function, quality of life and resource utilisation. A sample size of 750 participants (375 per arm) provides >90% power to detect a minimally important absolute difference of 8 on the 100-point patient-reported disability scale and a 25% relative risk reduction in complications, using a two-sided alpha value of 0.025 to account for the two primary outcomes. Analyses will follow intention to treat principles for all randomised participants. All participants will be followed to either death or up to 1 year. ETHICS AND DISSEMINATION: Ethical approval has been granted by Clinical Trials Ontario (Project ID: 1785) and our ethics review board (Protocol Approval #20190409-01T). Results will be disseminated through presentation at scientific conferences, through peer-reviewed publication, stakeholder organisations and engagement of social and traditional media. TRIAL REGISTRATION NUMBER: NCT04221295.

Prehabilitation-Driven Changes in Frailty Metrics Predict Mortality in Patients With Advanced Liver Disease.

INTRODUCTION: Frailty is a predictor of morbidity and mortality in cirrhosis. Although evidence for prehabilitation is promising, the data for liver transplant (LT) candidates are limited. The primary aim of this study was to evaluate the effect of a novel prehabilitation strategy on changes in frailty metrics and survival in LT candidates. The secondary aim was to determine liver-related and extrahepatic conditions associated with frailty. METHODS: In this ambispective cohort study, all patients underwent frailty assessment using the liver frailty index (LFI), 6-minute walk test, and gait speed test performed by a dedicated physical therapist. Home-based exercise prescription was individualized to each patient's baseline physical fitness. RESULTS: We included 517 patients (59% men, median age 61 years, and a model for end-stage liver disease score of 12) evaluated during 936 PT visits. Frailty metrics were affected by age, sex, and liver-related parameters, but not by model for end-stage liver disease. Patients with nonalcoholic fatty liver disease and alcohol-related cirrhosis had worse frailty metrics by all tools. We demonstrated the feasibility of prehabilitation in improving both LFI and 6-minute walk test, particularly in adherent patients. A median LFI improvement of 0.3 in frail patients was associated with improved survival in univariate analysis. Compliance with physical therapist visits (hazards ratio = 0.35 [0.18-0.67] for 2 visits and hazards ratio = 0.54 [0.31-0.94] for ≥3 visits) was independently associated with increased survival. DISCUSSION: Prehabilitation improves frailty metrics in LT candidates and is associated with a survival advantage. Our findings provide a framework for the standardized prehabilitation program in LT candidates while prioritizing compliance, adherence, and on-training LFI goal accomplishment.

Prehabilitation for Hepatopancreatobiliary Surgical Patients: Interim Analysis Demonstrates a Protective Effect From Neoadjuvant Chemotherapy and Improvement in the Frailty Phenotype.

BACKGROUND: Prehabilitation encompasses multidisciplinary interventions to improve health and lessen incidence of surgical deterioration by reducing physiologic stress and functional decline. This study presents an interim analysis to demonstrate prehabilitation for hepatopancreatobiliary (HPB) surgical patients. METHODS: In 2018, a structured prehabilitation pilot program was implemented. Eligibility required HPB malignancy, neoadjuvant chemotherapy, and residence within hour drive. Patients were enrolled into the 4-month program. The fitness component was composed of timed up and go test and grip strength with exercise recommendations. Nutrition involved evaluation of sarcopenic obesity, glucose management, and smoking and alcohol counseling. Psychological services included psychosocial assessments and advanced care planning, with social work referrals. Component were evaluated monthly by a physician using laboratory results, nutritional data and questionnaires, psychological assessments, and validated fitness tests. Nurse navigators spoke with patients weekly to monitor compliance. RESULTS: At 12 months, nineteen patients were enrolled. Ten completed prehabilitation, neoadjuvant chemotherapy and underwent their surgical procedure. There were no differences found after prehabilitation in functional status, physical performance, psychosocial assessments, or nutrition. Frailty, as assessed by Fried frailty criteria, improved significantly after prehabilitation (P < .0001). Symptom severity and laboratory values did not change. Length of stay was 6.5 days and all patients were discharged to home. There was 1 readmission for transient ischemic attack and 90-day mortality rate was 0%. DISCUSSION: Prehabilitation to improve recovery is a promising concept encompassing a wide array of multidisciplinary assessments and interventions. It may demonstrate a protective effect on physiologic decline from chemotherapy and may reverse frailty phenotypes.

Increased care at discharge from COVID-19: The association between pre-admission frailty and increased care needs after hospital discharge; a multicentre European observational cohort study.

BACKGROUND: The COVID-19 pandemic has placed significant pressure on health and social care. Survivors of COVID-19 may be left with substantial functional deficits requiring ongoing care. We aimed to determine whether pre-admission frailty was associated with increased care needs at discharge for patients admitted to hospital with COVID-19. METHODS: Patients were included if aged over 18 years old and admitted to hospital with COVID-19 between 27 February and 10 June 2020. The Clinical Frailty Scale (CFS) was used to assess pre-admission frailty status. Admission and discharge care levels were recorded. Data were analysed using a mixed-effects logistic regression adjusted for age, sex, smoking status, comorbidities, and admission CRP as a marker of severity of disease. RESULTS: Thirteen hospitals included patients: 1671 patients were screened, and 840 were excluded including, 521 patients who died before discharge (31.1%). Of the 831 patients who were discharged, the median age was 71 years (IQR, 58-81 years) and 369 (44.4%) were women. The median length of hospital stay was 12 days (IQR 6-24). Using the CFS, 438 (47.0%) were living with frailty (≥ CFS 5), and 193 (23.2%) required an increase in the level of care provided. Multivariable analysis showed that frailty was associated with an increase in care needs compared to patients without frailty (CFS 1-3). The adjusted odds ratios (aOR) were as follows: CFS 4, 1.99 (0.97-4.11); CFS 5, 3.77 (1.94-7.32); CFS 6, 4.04 (2.09-7.82); CFS 7, 2.16 (1.12-4.20); and CFS 8, 3.19 (1.06-9.56). CONCLUSIONS: Around a quarter of patients admitted with COVID-19 had increased care needs at discharge. Pre-admission frailty was strongly associated with the need for an increased level of care at discharge. Our results have implications for service planning and public health policy as well as a person's functional outcome, suggesting that frailty screening should be utilised for predictive modelling and early individualised discharge planning.

Prehabilitation: finally utilizing frailty screening data.

The elderly colorectal cancer patients tend to be frail, at nutrition risk with multiple comorbidities. In view of the stress on the body by surgery and recovery, it makes sense if patients are prepared before appropriately so that they can recover earlier and better. Prehabilitation prior to major surgery has attracted the attention of clinicians recently, and this review highlights the steps that need to be taken to implement a multidisciplinary program. Such programs requires a paradigm shift in the sense that all players need to be working in team for the benefit of patinets' outcome.

Modified frailty index and hypoalbuminemia as predictors of adverse outcomes in older adults presenting to acute general surgical unit.

INTRODUCTION: Health professionals are progressively drawing on the concept of frailty as a determinant of adverse surgical outcomes in of older adults. We aimed to determine the prevalence of frailty and the correlation between frailty and mortality among older adults admitted to the acute surgical unit. MATERIALS AND METHODS: This prospective cohort study was conducted in the acute general surgical unit over a two month period. We recruited 150 consecutive patients aged 65yrs and above. The modified frailty index was employed to measure frailty and the albumin levels on admission were obtained from electronic medical records. The patients were followed up for a period of thirty days. RESULTS: We found that more than 40% of the older adults admitted to the acute general surgical unit were frail and frailty was associated with higher rate of mortality at 30 days. Hypoalbuminemia was associated with a longer length of stay, higher rate of complications, and an increased likelihood of discharge to a rehabilitation facility. There was also a significant univariate correlation between frailty and the presence of hypoalbuminemia on admission. CONCLUSION: Frailty and hypoalbuminemia are common in older general surgical patients and predict the likelihood of some of the adverse outcomes relevant to older adults and health economy such as mortality, increased length of stay, rate of complications, and likelihood of discharge to a rehabilitation facility. Further studies should investigate a possible causal association between frailty and low albumin levels in an acute surgical setting.

Tapentadol prolonged release for pain control in a frail obese patient: a case report.

We present the case of a 59-year-old woman with third-grade obesity and severe comorbidities including osteoporosis, dyslipidemia, diabetes mellitus, hypertension, night eating following bariatric biliary-intestinal bypass surgery, severe fibromyalgia, poly-arthrosis, lumbar disc herniation in L5S1, sleep disorders and sleep apnea syndrome, and emotional disorders with anxiety and depression, who suffered from chronic pain unresponsive to a combination of multiple analgesics. After a period of metabolic and nutritional rehabilitation, analgesic treatment with tapentadol prolonged release (PR) was started and gradually increased to a daily dose of 300 mg with optimal pain control and a marked improvement in the quality of life and autonomy. Therapy suspension was followed by rebound pain with a worsening in functional capacity, and thus, the patient requested a new rehabilitation treatment, with new benefits. Analgesia is of paramount importance in fragile patients who are undergoing a rehabilitation period, in order to improve compliance with the rehabilitation protocols and increase the success of behavioral therapy. Tapentadol PR can be an effective analgesic therapy for pain control in several settings. Its peculiar tolerability profile improves the acceptability of tapentadol, even in patients with multiple previous analgesic treatments.

[Interest of follow-up of recommendations over a period of 6 months for elderly subjects who have been screened for frailty]. / Intérêt du suivi des préconisations sur une période de 6 mois pour des sujets âgés ayant bénéficié d'un dépistage de la fragilité.

Frailty is a partially reversible geriatric syndrome. Its prevention requires a structured screening, and is a major public health issue given the increasing life expectancy of the population. The observance of the recommendations made after a screening of the frailty patients is not well known. The objective of our research was to describe the characteristics of patients evaluated in a frailty-day-hospital and followed up recommendation adherence at 3 and 6 months. METHODS: patients aged over 65 years old with an ADL score of at least 5 out of 6, were evaluated according to the Fried score to classify patients into pre-frailty or frailty patients. According to the standardized geriatric assessment, recommendations were prescribed for each medico-social situation according to HAS recommendations. A follow-up assessment of these measures was carried out at home basis at 3 and 6 months. RESULTS: 82 patients were included, with mean age of 83.7±5.7 years. 99% were pre-frail or frail and received an average of 3.7±1.7 recommendations. At 3 months, there is an inverse correlation between number and follow-up compliance (r=-0.340, p=0.008), as well as at 6 months (r=-0.352, p=0.006). Between 3 and 6 months, there is a significant increase recommendation number followed (r=0.707, p=0.000). CONCLUSION: at 6 months, 74.3% recommendations were realized, with a significant increase of recommendation number between the 3rd and 6th month. This result is encouraging by showing the benefit of home support in recommendations follow-up.

25(OH) vitamin D and functional outcomes in older adults admitted to rehabilitation units: the safari study.

Vitamin D (25(OH)D) deficiency is associated with poor physical performance; little is known about its impact on geriatric rehabilitation. We found a positive non-linear relationship between 25(OH)D and functional gain, stronger in levels < 16 ng/ml (below the cutoff for "deficiency"). An early 25(OH)D dosage may be advisable for this population. INTRODUCTION: Vitamin D (25(OH)D) deficiency is highly prevalent in older people, and it is associated with poor muscular strength and physical performance. Its impact on functional outcomes during geriatric rehabilitation has been poorly studied. We aim to analyze the association between 25(OH)D and functional recovery in geriatric rehabilitation units. METHODS: We conducted a prospective multi-center cohort study including patients ≥ 65 years old admitted to 3 geriatric rehabilitation units in Italy and Spain, after orthopedic events or stroke. Outcomes were absolute functional gain (AFG, discharge-admission Barthel index) and ability to walk (AW) at 3 months after admission. The association between 25(OH)D quartiles (Q1-Q2-Q3-Q4) and outcomes was explored using linear or logistic regression models. RESULTS: We included 420 patients (mean age = 81.2 years [SD = 7.7], 66.4% females, mean 25(OH)D concentration = 13.5 ng/ml [SD = 8.7]) (to convert to nmol/l multiply by 2.496). A non-linear relationship between 25(OH)D and AFG was found, with a stronger association for 25(OH)D levels < 16 ng/ml. Compared to Q1 (25(OH)D ≤ 6 ng/ml), participants in Q3 (25(OH)D 11.5-18.2 ng/ml) had the best AFG and AW (mean AFG [SD], Q1 = 28.9 [27.8], Q2 = 32.5 [23.5], Q3 = 43.1 [21.9], Q4 = 34.5 [29.3], R2 = 7.3%; AW, Q1-Q2 = 80%, Q3 = 91%, Q4 = 86%). Regression models adjusted for potential confounders confirmed these results (AGF Q2, ß = 2.614, p = 0.49; Q3, ß = 9.723, p < 0.01; Q4, ß = 4.406, p = 0.22; AW Q2, OR [95% CI] = 1.84 [0.67-5.33]; Q3, OR [95% CI] = 4.01 [1.35-13.48]; Q4, OR [95% CI] = 2.18 [0.81-6.21]). CONCLUSIONS: In our study, 25(OH)D concentration showed a positive association with functional outcomes at 3 months. The association is stronger below the usual cutoff for "deficiency." Dosage of 25(OH)D concentration may help identify geriatric rehabilitation patients at risk for a worse functional recovery.

Prehabilitation is better than cure.

PURPOSE OF REVIEW: With a continuously growing number of older patients undergoing major surgical procedures, reliable parameters practicable in perioperative routine revealing those patients at risk are urgently needed. Recently, the concept of 'prehabilitation' with its key elements exercise, nutrition and psychological stress reduction especially in frail patients is attracting increasing attention. RECENT FINDINGS: Literature search revealed a huge amount of publications in particular within the last 12 months. Although a single definition of both frailty and prehabilitation is still to be made, various players in the perioperative setting obviously are becoming increasingly convinced about a possible benefit of the program - referring to different components and measures performed. Although physiologically advantages seem obvious, there is hardly any reliable data on clinical outcomes resulting from properly performed studies. This applies especially to octogenarians; thus those at risk for adverse events the concept originally addresses. SUMMARY: Identifying high-risk patients at the earliest possible stage and increasing their physiological reserve prior to surgery is a promising approach that seems to result in remarkable improvements for older patients. However, further studies on effectiveness in a highly heterogeneous population and agreement on a common concept are mandatory before a final judgement can be given.

Frailty Related Factors as Predictors of Functional Recovery in Geriatric Rehabilitation: The Sarcopenia And Function in Aging Rehabilitation (SAFARI) Multi-Centric study.

BACKGROUND: Frailty-related characteristics, such as sarcopenia, malnutrition and cognitive impairment, are often overlooked, both in clinical practice and research, as potential contributors to functional recovery during geriatric rehabilitation. OBJECTIVE: The aim of the study was to identify frailty-related characteristics associated with functional recovery in a cohort of post-orthopedic surgery and post-stroke older adults. DESIGN: Multi-centric cohort study. Participanst and Settings: Patients over 65 years, admitted to three geriatric rehabilitation units, in Spain and Italy, after an orthopedic event or a stroke, from December 2014 to May 2016. MEASUREMENTS: The Absolute Functional Gain (AFG) defined as the difference between Barthel Index score at discharge and at admission, and the Relative Functional Gain (RFG) that represents the percentage of recovery of the function lost due to the event, were selected as outcomes. Both outcomes were analyzed as continuous and dichotomous variables. Analyses were also stratified as diagnostic at admission. RESULTS: We enrolled 459 patients (mean age±SD=80.75±8.21 years), 66.2% women, 69.5% with orthopedic conditions and with a length of stay of 28.8±9.1 days. Admission after a stroke (Odds Ratio=0.36, 95% Confidence Interval=0.22-0.59]) and a better functional status at admission (OR=0.96, 95% CI=0.94-0.97), were associated with a lower likelihood of AFG, while a better pre-event Barthel index (OR=1.03 for each point in score, 95% CI=1.01-1.04), being able to walk (OR=2.07, 95% CI=1.16-3.70), and a better cognitive status at admission (OR=1.05, 95% CI=1.01-1.09), were associated with a higher chance of AFG. Post-stroke patients with delirium at admission had a re-duced chance of AFG (OR=0.25, 95% CI=0.07-0.91]). Patients admitted after an ortho-pedic event with better pre-event functional status (OR=1.04, 95% CI=1.02-1.06) and able to walk at admission (OR=2.79, 95% CI=1.29-6.03]) had an increased chance of AFG. Additionally, in both diagnostics groups, a better handgrip strength increased the chance of RFG. CONCLUSIONS: Among frailty-related variables, physical, cognitive and muscular function at admission could be relevant for functional improvement during geriatric reha-bilitation. If confirmed, this data might orient targeted interventions.

PREHAB study: a protocol for a prospective randomised clinical trial of exercise therapy for people living with frailty having cancer surgery.

INTRODUCTION: Exercise prehabilitation may improve outcomes after surgery. Frailty is a key predictor of adverse postoperative outcomes in older people; the multidimensional nature of frailty makes this a population who may derive substantial benefit from exercise prehabilitation. The objective of this trial is to test the efficacy of exercise prehabilitation to improve postoperative functional outcomes for people living with frailty having cancer surgery with curative intent. METHODS AND ANALYSIS: We will conduct a single-centre, parallel-arm randomised controlled trial of home-based exercise prehabilitation versus standard care among consenting patients >60 years having elective cancer surgery (intra-abdominal and intrathoracic) and who are frail (Clinical Frailty Scale >4). The intervention consists of > 3 weeks of exercise prehabilitation (strength, aerobic and stretching). The primary outcome is the 6 min walk test at the first postoperative clinic visit. Secondary outcomes include the short physical performance battery, health-related quality of life, disability-free survival, complications and health resource utilisation. The primary outcome will be analysed by intention to treat using analysis of covariance. Outcomes up to 1 year after surgery will be ascertained through linkage to administrative data. ETHICS AND DISSEMINATION: Ethical approval has been granted by our ethics review board (Protocol Approval #2016009-01H). Results will be disseminated through presentation at scientific conferences, through peer-reviewed publication, stakeholder organisations and engagement of social and traditional media. TRIAL REGISTRATION NUMBER: NCT02934230; Pre-results.

Feasibility and validity of frailty measurement in geriatric rehabilitation.

OBJECTIVES: The measurement of frailty using a Frailty Index (FI) has been criticised as too time-consuming for use in hospital settings. We aimed to assess the feasibility and characteristics of an FI derived from routinely collected data. METHODS: A total of 258 participants aged 65 and older were included in a single-centre prospective cohort study conducted in inpatient geriatric rehabilitation wards. The functional independence measure (FIM™), medication count and comorbidities were coded as deficits. RESULTS: An FI could be derived in all participants. It was normally distributed with a mean (SD) of 0.42 (0.13) and reached a submaximal limit of 0.69. Adjusting for age and sex, the odds ratio of a poor outcome (death/discharge to higher care) was 1.38 (confidence interval 1.11-1.70) per unit (0.1) increase in FI. CONCLUSION: Derivation of an FI from routinely collected data is feasible in geriatric rehabilitation settings and is predictive of poor outcomes.

Evaluation of a physiatrist-directed prehabilitation intervention in frail patients with colorectal cancer: a randomised pilot study protocol.

INTRODUCTION: Prehabilitation interventions have shown efficacy in the orthopaedic and cardiothoracic surgical populations, but there has been limited evidence for general surgical patients. We present the protocol for a pilot trial of a novel prehabilitation intervention, consisting of a physiatrist-directed preoperative assessment and treatment programme. METHODS AND ANALYSIS: This is a single-centre pilot randomised controlled trial investigating physiatrist-directed prehabilitation for a 4 to 6-week preoperative period. We will block randomise 40-50 participants awaiting surgery for colorectal cancer to prehabilitation versus control. Participants in the prehabilitation arm will undergo assessment by a physiatrist and enrol in a supervised exercise programme. The control group will not undergo any prehabilitation interventions in the preoperative period. Our primary outcome is feasibility, measured by examining recruitment, refusal, retention and adherence rates as well as participant satisfaction and feedback. Secondary outcomes include physical fitness, functional ability, health-related quality of life, postoperative complications, mortality, readmissions, length of stay, prehabilitation interventions performed and exercise complications. ETHICS AND DISSEMINATION: This study has been approved by the Hamilton Integrated Research Ethics Board (HIREB reference number 2015-0090-GRA). The results of this pilot study will be used to design a full-scale study and published in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT02531620; Pre-results.

Prevalence of frailty and its association with sociodemographic and clinical characteristics, and resource utilization in a population of Singaporean older adults.

AIM: The present study examined the prevalence of frailty and its association with sociodemographic, clinical and social characteristics, and service utilization in a representative general population sample of Singaporean older adults. METHODS: A single-phase, cross-sectional survey was carried out in a nationally representative sample of 2102 Singapore residents aged 60 years and older. Five frailty parameters (weakness, slowness, exhaustion, low physical activity and/or unintentional weight loss) were measured to assess Fried's frailty phenotype to identify frail (meeting 3/5 criteria), prefrail (meeting 1 or 2 criteria) and non-frail (absence of all 5) older adults. On testing independent associations, multiple backward stepwise logistic regression analyses were carried out to identify the strongest correlates of frail states. RESULTS: The prevalence of frailty among the older adult population was found to be 5.7%. Sociodemographic, clinical and social characteristics differed significantly at an independent level by frailty status. A higher proportion of frail older adults had care needs (54.5%) compared to pre-frail (13.5%) and non-frail (2.2%), and poor social networks (58.8% vs prefrail [36.6%] and non-frail [28.6%]). Frail older adults also had significantly higher service utilization. Significant correlates of frail state were older age, poor social networks, having any care need, and a history of dementia, diabetes, cancer, respiratory problems or paralysis. CONCLUSIONS: Frailty is common among older adults in Singapore, and it correlates with many components at the person, health and societal levels, thus highlighting the importance of individual- and population-level frailty detection and interventions in this population.
