Frailty and body composition predict adverse outcomes after emergency general surgery admission: a multicentre observational cohort study.

Emergency surgical admissions represent the most unwell patients admitted to any hospital. Frailty and body composition independently identify risk of adverse outcomes but are seldom combined to predict outcomes in emergency patients. We aim to determine the relationships between frailty, body composition analyses (BCA) and mortality in an undifferentiated emergency general surgical patient population. A prospective, multicentre observational cohort study of patients admitted with emergency surgical pathology was conducted in eight hospitals. BCA were performed at L3 vertebrae using computed tomography images to quantify sarcopenia and myosteatosis. Sex-specific BCA cut-off values were determined by our previous study. Reported Edmonton Frail Scale (REFS) values ≥8 identified frailty. The primary outcomes were all-cause 30-day and 1-year mortality. Multivariable logistic regression was utilised to explore predictive relationships between frailty, BCA, mortality and independent discharge. A total of 194 patients were included; 24% were frail, 25% were sarcopenic and 23% myosteatotic. Some 61% of patients underwent an emergency laparotomy. Frail patients were more likely to be sarcopenic (20.4% vs 40.4%; p = 0.011) and myosteatotic (27.2% vs 51.1%; p = 0.004). Thirty-day and 1-year mortality was 5.2% and 15.5%, respectively; 30-day mortality was two times higher in the frail group (4.1% vs 8.5%; p = 0.414), and three times higher at 1 year (10.2% vs 31.9%; p = 0.001). Age (odds ratio [OR] 1.06; p = 0.001), sarcopenia (OR 2.88; p = 0.047) and frailty (OR 4.13; p = 0.001) were associated with 1-year mortality. Only 55.3% of frail patients were discharged home independently compared with 88.4% non-frail patients (p < 0.001). One-year mortality was greater in those with frailty and/or BCA abnormalities than in those without (28.8% vs 9.6%; p = 0.003). Frailty, sarcopenia and myosteatosis contribute significantly to adverse outcomes. NCT03534765.

Prognostic accuracy of eight frailty instruments for all-cause mortality in Australian primary care

AimTo investigate the ability of eight frailty instruments to accurately predict all-cause mortality and other adverse outcomes in Australian primary care patients. MethodsStudy participants included adults aged ≥75 years attending one of three primary care clinics in South Australia. Frailty instruments studied were Fried's frailty phenotype (FFP), the Frailty Index (FI) of cumulative deficits, Kihon Checklist (KCL), the Fatigue Resistance Ambulation Illness and Loss of weight (FRAIL) scale, Groningen Frailty Indicator (GFI), PRISMA-7, Reported Edmonton Frail Scale (REFS), and gait speed. Primary outcomes were all-cause mortality at 12- and 24-months. Secondary outcomes included falls, general practice attendance, hospital admission and emergency department (ED) presentation at 12-months. Results243 participants (55.6 % female) with a mean (SD) age of 80.2 (4.6) years were included. 29 participants (16.6 %) were classified as frail at baseline by FFP. All frailty instruments demonstrated a significant ability to predict 12- and 24-month mortality. The REFS showed the highest auROC for both 12- and 24-month mortality. The REFS, Frailty Index, Kihon Checklist, FRAIL scale, and gait speed showed excellent discriminative ability for 12-month mortality (auROC ≥ 0.8 - >0.9), while the remainder showed acceptable discrimination. All frailty instruments, with the exception of the GFI, showed an excellent discriminative ability for 24-month mortality (auROC 0.8-<0.9). ConclusionsAll frailty instruments possessed adequate discriminative ability for all-cause mortality predicting in older primary care patients. Frailty measurement is thus a valuable strategy to identify older patients at risk of mortality and can guide clinical decision-making in primary care settings.

Prevalence and Factors Associated With Frailty Among Older Adults Living With HIV Compared to Their Uninfected Peers From the Kenyan Coast.

Objectives: a) To document the prevalence and correlates of frailty among older adults living with HIV (OALWH) and their uninfected peers, and b) Investigate HIV status as an independent predictor of frailty. Methods: This cross-sectional study was conducted between 2020 and 2021 at the Kenyan coast among 440 older adults aged ≥50years (257 OALWH). Frailty was assessed using the Reported Edmonton Frail Scale. Logistic regression was used to examine the correlates of frailty. Results: The prevalence of frailty was significantly higher among OALWH (24%) than their uninfected peers (13%). HIV seropositivity was not independently associated with frailty. Sleeping difficulties, ageism, higher waist/hip ratio, visiting traditional healers, HIV treatment change/interruption, prolonged illness following HIV diagnosis, and self-reported diabetes were significantly associated with higher odds of frailty. Residing in larger households, having higher income, having friends, being male and light physical activities were significantly associated with reduced odds of frailty. Conclusion: The prevalence of frailty is elevated among OALWH; however, factors other than HIV are predominant, particularly psychosocial factors. Multicomponent interventions are needed to prevent/delay and manage frailty in this setting.

Preoperative Frailty Is an Independent Risk Factor for Postinduction Hypotension in Older Patients Undergoing Noncardiac Surgery: A Retrospective Cohort Study.

Intraoperative hypotension is a risk factor for perioperative adverse outcomes and is highly prevalent in older patients. Frailty has been associated with hemodynamic instability but its impact on postinduction hypotension is unclear. Therefore, we assessed the association between frailty and postinduction hypotension in older patients. We retrospectively evaluated electronic medical records of patients aged ≥65 years who were assessed for preoperative frailty and underwent noncardiac surgery under general anesthesia. Reported Edmonton Frail Scale (REFS) scores were used to stratify patients into a nonfrail (REFS scores 0-5), prefrail (6-7), and frail (8-18) groups. Postinduction hypotension was defined as a mean blood pressure below 65 mmHg or 20% from baseline occurring within the first 20 minutes after anesthesia induction and evaluated using multivariate logistic regression analysis. Independent factors related to postinduction hypotension in our sample (421 patients) were status of frail (REFS score ≥8) compared to nonfrail (odds ratio [OR], 2.73; 95% confidence interval [CI], 1.44-5.18; p = .002), lower baseline mean blood pressure in the operating room (OR, 0.98; 95% CI, 0.96-0.999; p = .034) and at the presurgical center (OR, 0.96; 95% CI, 0.94-0.99; p = .003), and orthopedic (compared to urologic) surgery (OR, 2.22; 95% CI, 1.14-4.30; p = .019). Preoperative frail status based on REFS scores is associated with postinduction hypotension. Frailty screening tool for older patients may enhance traditional risk calculators and improve patient selection for noncardiac surgery under general anesthesia.

Frailty and pain in an acute private hospital: an observational point prevalence study

Frailty and pain in hospitalised patients are associated with adverse clinical outcomes. However, there is limited data on the associations between frailty and pain in this group of patients. Understanding the prevalence, distribution and interaction of frailty and pain in hospitals will help to determine the magnitude of this association and assist health care professionals to target interventions and develop resources to improve patient outcomes. This study reports the point prevalence concurrence of frailty and pain in adult patients in an acute hospital. A point prevalence, observational study of frailty and pain was conducted. All adult inpatients (excluding high dependency units) at an acute, private, 860-bed metropolitan hospital were eligible to participate. Frailty was assessed using the self-report modified Reported Edmonton Frail Scale. Current pain and worst pain in the last 24 h were self-reported using the standard 0–10 numeric rating scale. Pain scores were categorised by severity (none, mild, moderate, severe). Demographic and clinical information including admitting services (medical, mental health, rehabilitation, surgical) were collected. The STROBE checklist was followed. Data were collected from 251 participants (54.9% of eligible). The prevalence of frailty was 26.7%, prevalence of current pain was 68.1% and prevalence of pain in the last 24 h was 81.3%. After adjusting for age, sex, admitting service and pain severity, admitting services medical (AOR: 13.5 95% CI 5.7–32.8), mental health (AOR: 6.3, 95% CI 1. 9–20.9) and rehabilitation (AOR: 8.1, 95% CI 2.4–37.1) and moderate pain (AOR: 3.9, 95% CI 1. 6–9.8) were associated with increased frailty. The number of older patients identified in this study who were frail has implications for managing this group in a hospital setting. This indicates a need to focus on developing strategies including frailty assessment on admission, and the development of interventions to meet the care needs of these patients. The findings also highlight the need for increased pain assessment, particularly in those who are frail, for more effective pain management.Trial registration: The study was prospectively registered (ACTRN12620000904976; 14th September 2020).

Prevalence and health outcomes of polypharmacy and hyperpolypharmacy in older adults with frailty: A systematic review and meta-analysis.

Polypharmacy is a prevalent issue in older adults, associated with a wide range of adverse health outcomes, amplified in those with frailty. This review aims to synthesize current literature on the prevalence and health outcomes of polypharmacy and hyperpolypharmacy in older adults with frailty. A systematic search was carried out within ten databases till December 2021. Data was extracted using a piloted data extraction form, and methodological quality was assessed using JBI critical appraisal checklists. Meta-analyses were conducted for prevalence, and narrative synthesis was conducted for the health outcomes of polypharmacy and hyperpolypharmacy in older adults with frailty. Heterogeneity was assessed using Chi2 and I2 statistics, with sensitivity and subgroup analyses performed to explore sources of heterogeneity. Sixty-six studies were included for this review. The overall pooled prevalence of polypharmacy and hyperpolypharmacy was 59% and 22% respectively. When stratifying the studies by setting, WHO regions, in eighteen frailty assessment instruments, and by its year of publication, subgroup analysis found the highest rates of prevalence in the hospital setting (71%), in the European region (68%), when Reported Edmonton Frail Scale was used (96%), and in studies published in 2015 (86%). Additionally, frail older adults with polypharmacy were less likely to experience an improvement in frailty states, had higher risks of mortality, were more likely to suffer adverse hospital-related outcomes, and required additional assistance compared to those without polypharmacy. Therefore, the high prevalence and poorer health outcomes urges the healthcare providers and health policymakers to develop and implement preventative and restorative measures targeted at the adverse outcomes associated with polypharmacy and hyperpolypharmacy in older adults with frailty.

Frailty in the over 65’s undergoing elective surgery (FIT-65) – a three-day study examining the prevalence of frailty in patients presenting for elective surgery

BackgroundFrailty increases the risk of perioperative complications, length of stay, and the need for assisted-living after discharge. As the UK population ages the number of frail patients presenting for elective surgery in the UK is likely to grow. Despite the potential benefits of early diagnosis, frailty is not uniformly screened for in UK elective surgical patients and its prevalence remains unclear. The primary aim of this study was to assess the prevalence of frailty in patients aged over 65 years undergoing elective surgery.MethodsWe performed a prospective cross-sectional observational study in eight UK hospitals. Data were collected over three consecutive days with follow-up at 30 days. HRA approval was obtained (REC 20/SC/0121) and signed informed consent obtained. Participants were eligible for inclusion if they were 65 years or older and undergoing elective surgery. Pre-operative data were collected from hospital notes by anaesthetic trainees. A member of the research team blinded to the pre-operative dataset screened each participant for frailty pre-operatively using the Reported Edmonton Frail Scale (REFS). Post-operative data were collected from the notes on day of surgery and at 30 days. Participants were defined as “frail” if they scored 8 or more on the REFS.ResultsTwo hundred twenty eight participants were recruited during the study period of whom 218 proceeded to surgery. There were 103 females and 115 males. Median age was 75 years (interquartile range 70–80). Thirty-seven participants (17.0%) were identified as frail. Frail patients were older, had a higher ASA score, were more likely to have carers and were more likely to be anaemic or present with ECG abnormalities. There were no differences in gender, BMI, place of residence or smoking status for patients identified as frail versus non-frail. There was no difference in length-of-stay between frail and non-frail patients, although those identified as frail were less likely to be discharged to their own home.ConclusionWe found the prevalence of frailty in a mixed population of elective surgical patients aged 65 or over to be 17.0%. Furthermore, we found the REFS to be a practical tool for pre-operative frailty screening. Frail patients presented for elective surgery with modifiable co-morbidities which could have been optimised pre-operatively. Early screening could highlight frail patients, allowing time for pre-operative planning and evidence-based optimisations of comorbidities. We therefore encourage the adoption of frailty assessment as a routine part of pre-operative assessment.

Walking Speed Assessed by 4-Meter Walk Test in the Community-Dwelling Oldest Old Population in Vietnam.

This study aims to provide data on usual walking speed in individuals aged 80 years or older and determine the association between walking speed and related factors in community-dwelling older adults. A cross-sectional study design was conducted to measure walking speed on community-dwelling elders aged 80 years or older in Soc Son district, Vietnam. Walking speed was assessed by a 4-Meter Walk Test with a usual-pace walking mode. Health-related characteristics of participants including risk of falls (The Timed Up and Go test, activities of daily living (ADL), instrumental activities of daily living (IADLs), cognitive impairment (Mini-Cog test) and frailty syndrome (The Reported Edmonton Frail Scale (REFS)). Multiple logistic regression was used to analyze the association between a slow walking speed and selected factors. A total of 364 older people were recruited, and the majority were female (65.4%). The overall average walking speed was 0.83 ± 0.27 m/s. The proportion of participants with a slow walking speed (<0.8 m/s) was 40.4%. Multiple logistic regression analyses showed that age, female, high fall risk (assessed by TUG test), ADL/IADL dependence and frailty syndrome had a negative effect on slow walking speed in this population. The results could provide useful reference data for further investigations and measures in clinical practice.

Development and validation of a frailty index based on data routinely collected across multiple domains in NSW hospitals.

To develop and validate a frailty index (FI) that covers multiple domains, using routine hospital data. To investigate the FI's validity, after excluding medication-related items (FI-ExMeds), for studies of frailty and polypharmacy. A FI was derived from routine NSW hospital data following standard published guidance. In a development cohort (151 inpatients≥70years), the FI was correlated with the Reported Edmonton Frail Scale (REFS) using Pearson's R. Validity and distribution of FI and FI-ExMeds, and correlation with each other, were evaluated in a validation cohort (999 inpatients≥75years). The mean FI for the development cohort was 0.27 (SD 0.09). The FI showed moderate linear correlation with the REFS (n=148, R=0.52, P<.001). In the validation cohort, mean FI (n=993) and FI-ExMeds (n=990) were both 0.28 (SD 0.11). FI-ExMeds showed high linear correlation with the FI (n=990, R=0.99, P<.001). This multi-domain FI is comparable to REFS, with adequate redundancy to exclude deficits for specific analyses.

The Effect of Minimally Invasive Surgery and Sternotomy on Physical Activity and Quality of Life

The aim of this study was to compare minimally invasive surgery (MI) and median sternotomy (MS) in terms of post-procedure health-related quality of life (HRQoL) and functional outcome. We conducted a multicentre prospective cohort study that enrolled patients from January 2015 until February 2017. Combined cardiac procedures were performed with MS and isolated valve procedures with either MS or MI, depending on patient preference and surgeon experience. HRQoL was measured using the five-level version of the EQ-5D (EQ-5D-5L) and physical activity before and after surgery was evaluated using a wearable accelerometer. Activity patterns and intensity recorded by the accelerometer in each period were classified as "sedentary", "light physical activity", "moderate physical activity", and "vigorous physical activity" for each patient. We also conducted a sub-analysis of frail patients in each group, as identified by the Reported Edmonton Frail Scale (>10 points). Patients were followed for 1 year. The study included 100 consecutive patients who underwent MI (n=50) or MS (n=50) during the study period. Patients in the MI group showed a faster recovery of physical activity in the immediate postoperative period and superior HRQoL in the first 3 months (both p<0.001) versus the MS group. Differences between the MI and MS group were indistinguishable over a longer follow-up. A similar correlation was observed in the frailty subanalysis. Overall, the MS group had a higher cumulative incidence of events than the MI group (p<0.001). Compared to conventional MS, MI was associated with better HRQoL and early functional outcome, even in frail patients.

The Utility of Psoas Muscle Assessment in Predicting Frailty in Patients Undergoing Transcatheter Aortic Valve Replacement.

Background The rise in an ageing population has resulted in an increase in the prevalence of aortic stenosis. With the advent and rapid expansion in the use of transcatheter aortic valve replacements (TAVRs), patients with severe aortic stenosis, traditionally thought too high risk for surgical intervention, are now being treated with generally favourable results. Frailty is an important factor in determining outcome after a TAVR, and an assessment of frailty is fundamental in the identification of appropriate patients to treat. Objective The objective of the study was to identify if the psoas muscle area is associated with frailty in TAVR patients and outcome after intervention. Method In this prospective study, we measured outcomes of 62 patients who underwent TAVR procedures against the psoas muscle area and the Reported Edmonton Frail Scale (REFS). Our aim was to assess if psoas muscle assessment can be used as a simple method to predict frailty in our population group. Results A total of 60 patients met the study criteria. Mean psoas-lumbar vertebral index was 0.61, with a lower value in the frail group. There was not a statistically significant correlation between the psoas measures, REFS score (indicative of frailty), and mortality. However, there was a statistically significant relationship between the psoas size and REFS score (p=0.043). Conclusion Psoas assessment can be useful in providing additional information when planning for patients to undergo a TAVR and can be used as a screening tool to help identify frail patients within this high-risk group.

Direct oral anticoagulants for patients aged over 80 years in nonvalvular atrial fibrillation: the impact of frailty.

In patients aged at least 80 years, atrial fibrillation is responsible for significant morbidity and mortality, with a high incidence of stroke. Four new direct oral anticoagulants (DOACs) have been introduced in Italy for the prevention of thromboembolism. Their safety and efficacy in the elderly have already been confirmed. Frailty is frequently associated with aging, but only a few studies have paid attention to interactions between frailty and anticoagulation therapy. We retrospectively evaluated the effectiveness and safety of DOACs in a population aged at least 80 years. Frailty was appraised using an adaptation of the Reported Edmonton Frail Scale, considering a value at least 8 (on a scale from 0 to 18). The majority (644/731) of patients remained on DOACs for more than 1 year. A total of 19 patients experienced a thrombotic event while on anticoagulation (1.11 events per 100 person-years) and 26 patients a major bleeding episode (1.52 events per 100 person-years). The probability of interrupting therapy increased significantly with frailty [hazard ratio 2.91 with confidence interval (CI) 2.15-3.92 at univariate analysis, hazard ratio 2.80 with CI 2.03-3.86 at multivariate]; frailty showed a significant impact also on major bleeding (hazard ratio 3.28 with CI 1.45-7.37 at univariate analysis, hazard ratio 3.56 with CI 1.58-8.01 at multivariate). Our study highlights how DOACs are a safe and effective option for anticoagulation, even in frail elderly people; the introduction of these drugs is leading to an increased use of anticoagulation therapy in this population. Prospective trials will be needed to reinforce these results and to consider new variables in the thrombotic and hemorrhagic risk scores underlying the prescription of DOACs.

Preoperative Frailty Predicts Postoperative Neurocognitive Disorders After Total Hip Joint Replacement Surgery.

Frailty is a reduced capacity to recover from a physiologically stressful event. It is well established that preoperative frailty is associated with poor postoperative outcomes, but it is unclear if this includes cognitive decline following anesthesia and surgery. This retrospective observational study was a secondary analysis of data from a previous study (the Anaesthesia, Cognition, Evaluation [ACE] study). We aimed to identify if preoperative frailty or prefrailty is associated with preoperative and postoperative neurocognitive disorders or postoperative cognitive dysfunction. The ACE study enrolled 300 participants aged ≥60 scheduled for elective total hip joint replacement and who underwent a full neuropsychological assessment at baseline and 3 and 12 months postoperatively. We applied patient data to 2 frailty models; both were based on an accumulation of deficits score: the reported Edmonton frail scale (REFS) and the comprehensive geriatric assessment-frailty index (CGA-FI) based on the comprehensive geriatric assessment. We calculated these 2 scores using baseline data collected from the medical history, demographic and clinical data as well as self-reported questionnaires. Some items on the REFS (3 of 18 or 17%) and the CGA-FI (37 of 51 or 27%) did not have an equivalent item in the ACE data. The mean age (standard deviation [SD]) was 70.1 years (6.6) with more women (197 [66%]). Using the REFS model, 40 of 300 (13.3%) patients were classified as vulnerable, mild, or moderately frail. Using the CGA-FI model, 69 of 300 (23%) were classified as intermediate or high frailty. The REFS and the CGA-FI were strongly correlated (r = 0.75; P < .01) with 34 of 300 (11%) meeting criteria for frailty by both the REFS and the CGA-FI.Frailty or prefrailty was associated with cognitive decline at 3 and 12 months using the REFS (odds ratio [OR], 1.51, 95% confidence interval [CI], 1.02-2.23 and OR, 2.00, 95% CI, 1.26-3.17, respectively) after adjusting for baseline mini-mental state examination (MMSE), smoking, hypertension, diabetes, history of acute myocardial infarction (AMI), and estimated intelligence quotient (IQ). Age did not modify this association. After adjusting for multiple comparisons, 3-month cognitive decline was no longer significantly associated with baseline frailty. This retrospective analysis demonstrates an association between baseline frailty and postoperative neurocognitive disorders, particularly using the more extensive REFS scoring method. This supports preoperative screening for frailty to risk-stratify patients, and identify and implement preventive strategies and to improve postoperative outcomes for older individuals.

Feasibility and acceptability of commonly used screening instruments to identify frailty among community-dwelling older people: a mixed methods study

BackgroundFrailty exposes older people to an elevated risk of a range of negative outcomes. Emerging evidence that frailty can be effectively treated within community settings has stimulated calls for more proactive screening within primary care. Assessing feasibility is a critical preliminary step in assessing the efficacy of interventions such as screening. However, few studies have explored the feasibility and acceptability of administering frailty screening instruments within general practice, and even fewer have incorporated patient perspectives. Our study had three objectives: To 1) assess overall feasibility of the instruments (completion time and rate); 2) assess patient acceptability towards the instruments; and 3) assess the feasibility and acceptability of the instruments to administering nurses.MethodsThe feasibility and acceptability of several frailty screening instruments (PRISMA-7, Edmonton Frail Scale, FRAIL Scale Questionnaire, Gait Speed, Groningen Frailty Indicator, Reported Edmonton Frail Scale and Kihon Checklist) was explored within the context of a larger diagnostic test accuracy (DTA) study. Completion time and rate was collected for all participants (N = 243). A sub-sample of patients (n = 30) rated each instrument for ease of completion and provided comment on perceived acceptability. Lastly, five of six administering nurses involved in the DTA study participated in semi-structured face-to-face interviews, rating the instruments against several feasibility and acceptability criteria (time, space, equipment, skill required to implement, acceptability to patients and nurses, ease of scoring) and providing comment on their responses.ResultsThe PRISMA-7 returned the highest overall feasibility and acceptability, requiring minimal space, equipment, skills and time to implement, and returning the fastest completion rate and highest patient and nurse acceptability rating. All screening instruments were faster to implement than the two reference standards (Fried’s Frailty Phenotype and Frailty Index). Self-administered instruments were subject to lower rates of completion than nurse-administered instruments.ConclusionsThis study has demonstrated that a number of commonly used frailty screening instruments are potentially feasible for implementation within general practice. Ultimately, more research is needed to determine how contextual factors, such as differences in individual patient and clinician preferences, setting and system factors, impact on the feasibility of screening in practice.

The Reported Edmonton Frail Scale-Thai version: Development and Validation of a Culturally-Sensitive Instrument.

Frailty may lead to increased vulnerability, disability, and adverse health outcomes in older adults. Early detection has been described as the best approach to manage frailty; however, frailty instruments are not widely available, particularly in the Thai language. The purpose of this cross‐sectional study was to develop a culturally adapted Thai version of the Reported Edmonton Frail Scale and to validate the psychometric properties of the new instrument in hospitalized older Thai adults. Reliability and validity were examined. Participants completed questionnaires that included demographic and health information, and the Reported Edmonton Frail Scale–Thai version. Results revealed that the new instrument was reliable and had good content validity. Inter‐rater reliability was strong. Confirmatory factor analysis showed a fair fit for the whole model, but most domains were strongly associated with frailty. On average, the instrument was completed under 7 minutes. The Thai version of the frailty instrument may be a practical tool for frailty evaluation, and could inform inpatient care, both locally and internationally; future research is needed to confirm predictability and feasibility in other clinical settings and populations.

Frailty and Co-Prescribing of Potentially Interacting Drugs in New Users of Warfarin.

BackgroundWarfarin is underutilised in frail older people because of the fear of bleeding complications. Drug interactions are an independent bleeding risk factor. However, the extent to which potential drug interactions are taken into account at warfarin therapy initiation in frail patients is not known.ObjectiveThe objective of this study was to investigate the use of potentially interacting drugs increasing the bleeding risk before and after warfarin initiation in frail and non-frail patients.MethodsWe conducted an observational study including inpatients aged ≥ 60 years initiated on warfarin in a tertiary hospital in Adelaide, South Australia. Frailty status was assessed with the Reported Edmonton Frail Scale. Medication charts were reviewed before and after warfarin initiation.ResultsIn total, 151 patients (102 non-frail and 49 frail) were included. Before warfarin initiation, the use of clopidogrel and acetaminophen was more common in frail patients compared with non-frail patients (25.5% vs 10.2%, p = 0.0135, 63.8% vs 35.7% p = 0.0014, respectively). The use of non-steroidal anti-inflammatory drugs, 9.2% in non-frail patients and 6.4% in frail patients before warfarin initiation, was completely stopped after warfarin initiation in both groups. The use of antiplatelet drugs decreased from 56.1% in non-frail patients and 66.0 % in frail patients to 12.2% and 14.9%, respectively. Instead, the use of drugs affecting the metabolism of warfarin or vitamin K increased in both groups. No statistically significant difference was seen in the exposure to interacting drugs between study groups after warfarin initiation. Acetaminophen, senna glycosides and cytochrome P450 2C9 inhibiting drugs were the most common interacting drugs at discharge used in 49.0%, 18.4% and 20.4% of non-frail patients and 53.2%, 29.8% and 19.1% of frail patients, respectively.ConclusionsThe overall frequency of potential drug interactions was moderate and frail patients were not exposed to warfarin drug interactions more often than non-frail patients. Further studies in larger study populations are required to verify these results.Electronic supplementary materialThe online version of this article (10.1007/s40266-020-00755-0) contains supplementary material, which is available to authorized users.

Frailty in Older Patients with Acute Coronary Syndrome in Vietnam.

BackgroundThere has been limited evidence about frailty in older patients with acute coronary syndrome (ACS) in Vietnam.Aim(1) To investigate the prevalence of frailty in older patients hospitalised with ACS and its associated factors; (2) To investigate the impact of frailty on percutaneous coronary intervention (PCI) and adverse outcomes in this population.MethodsPatients aged ≥60 with ACS admitted to two teaching hospitals in Vietnam were recruited from 9/2017 to 4/2018. Frailty was defined by the Reported Edmonton Frail Scale. Multivariate logistic regression was applied to investigate the associated factors of frailty and the impact of frailty on PCI and adverse outcomes.ResultsThere were 324 participants, mean age 73.5±8.3, 39.2% female. The prevalence of frailty was 48.1%. Advanced age, female gender, history of hypertension, heart failure, stroke and chronic kidney disease were significantly associated with a frailty status. Overall, 50.3% of the participants received PCI (58.3% in the non-frail vs 41.7% in the frail, p=0.003). However, frailty did not have an independent impact on PCI (adjusted OR 0.66, 95% CI 0.41–1.08). Frailty was significantly associated with increased risk of having arrhythmia during hospitalisation (adjusted OR 2.24, 95% CI 1.32–3.80), hospital-acquired pneumonia (adjusted OR 2.27, 95% CI 1.24–4.17), in-hospital mortality (adjusted OR 3.02, 95% CI 1.35–6.75), 30-day mortality (adjusted OR 3.28, 95% CI 1.59–6.76), and 30-day readmission (adjusted OR 2.53, 95% CI 1.38–4.63).ConclusionIn this study, frailty was present in nearly half of older patients with ACS and was associated with increased adverse outcomes. These findings suggest that frailty screening should be performed in older patients with ACS in Vietnam.

Commonly Used Screening Instruments to Identify Frailty Among Community-Dwelling Older People in a General Practice (Primary Care) Setting: A Study of Diagnostic Test Accuracy

Rapid frailty screening remains problematic in primary care. The diagnostic test accuracy (DTA) of several screening instruments has not been sufficiently established. We evaluated the DTA of several screening instruments against two reference standards: Fried's Frailty Phenotype [FP] and the Adelaide Frailty Index [AFI]), a self-reported questionnaire. DTA study within three general practices in South Australia. We randomly recruited 243 general practice patients aged 75+ years. Eligible participants were 75+ years, proficient in English and community-dwelling. We excluded those who were receiving palliative care, hospitalized or living in a residential care facility.We calculated sensitivity, specificity, predictive values, likelihood ratios, Youden Index and area under the curve (AUC) for: Edmonton Frail Scale [EFS], FRAIL Scale Questionnaire [FQ], Gait Speed Test [GST], Groningen Frailty Indicator [GFI], Kihon Checklist [KC], Polypharmacy [POLY], PRISMA-7 [P7], Reported Edmonton Frail Scale [REFS], Self-Rated Health [SRH] and Timed Up and Go [TUG]) against FP [3+ criteria] and AFI [>0.21]. We obtained valid data for 228 participants, with missing scores for index tests multiply imputed. Frailty prevalence was 17.5% frail, 56.6% prefrail [FP], and 48.7% frail, 29.0% prefrail [AFI]. Of the index tests KC (Se: 85.0% [70.2-94.3]; Sp: 73.4% [66.5-79.6]) and REFS (Se: 87.5% [73.2-95.8]; Sp: 75.5% [68.8-81.5]), both against FP, showed sufficient diagnostic accuracy according to our prespecified criteria. Two screening instruments-the KC and REFS, show the most promise for wider implementation within general practice, enabling a personalized approach to care for older people with frailty.
