Frailty in older inpatients: what physicians need to know

Exercise as a falls prevention strategy in the care of older people

Older people who sustain a fall may experience a range of adverse outcomes, such as distress, injury and loss of independence. Falls increase the risk of frailty and frailty increases the risk of falls. Regular exercise is a pillar of falls prevention and can have extensive benefits for older people's health, well-being and ability to undertake activities they enjoy. As part of the multidisciplinary team, nurses have a pivotal role in implementing exercise-based falls prevention strategies for older people and in encouraging their patients to exercise. This article discusses exercise as a falls prevention strategy in hospital and in the community and supports nurses to develop their knowledge and confidence in promoting exercise in older people.

Perspectives on the representation of frailty in the electronic frailty index

BACKGROUND

Frailty is a state of increased vulnerability from physical, social, and cognitive factors resulting in greater risk of negative health-related outcomes and increased healthcare expenditure. A 36-factor electronic frailty index (eFI) developed in the United Kingdom calculates frailty scores using electronic medical record data. There is currently no standardization of frailty screening in Canadian primary care. In order to implement the eFI in a Canadian context, adaptation of the tool is necessary because frailty is represented by different clinical terminologies in the UK and Canada. In considering the promise of implementing an eFI in British Columbia, Canada, we first looked at the content validation of the 36-factor eFI. Our research question was: Does the eFI represent frailty from the perspectives of primary care clinicians and older adults in British Columbia?

METHODS

A modified Delphi using three rounds of questionnaires with a panel of 23 experts (five family physicians, five nurse practitioners, five nurses, four allied health professionals, four older adults) reviewed and provided feedback on the 36-factor eFI. These professional groups were chosen because they closely work as interprofessional teams within primary care settings with older adults. Older adults provide real life context and experiences. Questionnaires involved rating the importance of each frailty factor on a 0-10 scale and providing rationale for ratings. Panelists were also given the opportunity to suggest additional factors that ought to be included in the screening tool. Suggested factors were similarly rated in two Delphi rounds.

RESULTS

Thirty-three of the 36 eFI factors achieved consensus (> 80% of panelists provided a rating of ≥ 8). Factors that did not achieve consensus were hypertension, thyroid disorder and peptic ulcer. These factors were perceived as easily treatable or manageable and/or not considered reflective of frailty on their own. Additional factors suggested by panelists that achieved consensus included: cancer, challenges to healthcare access, chronic pain, communication challenges, fecal incontinence, food insecurity, liver failure/cirrhosis, mental health challenges, medication noncompliance, poverty/financial difficulties, race/ethnic disparity, sedentary/low activity levels, and substance use/misuse. There was a 100% retention rate in each of the three Delphi rounds.

CONCLUSIONS AND NEXT STEPS

Three key findings emerged from this study: the conceptualization of frailty varied across participants, identification of frailty in community/primary care remains challenging, and social determinants of health affect clinicians' assessments and perceptions of frailty status. This study will inform the next phase of a broader mixed-method sequential study to build a frailty screening tool that could ultimately become a standard of practice for frailty screening in Canadian primary care. Early detection of frailty can help tailor decision making, frame discussions about goals of care, prevent advancement on the frailty trajectory, and ultimately decrease health expenditures, leading to improved patient and system level outcomes.

Factors Determining the Occurrence of Frailty Syndrome in Hospitalized Older Patients

Frailty syndrome (FS) is a condition characterized by a decline in reserves, observed with aging. The most important consequences of the frailty syndrome include disability, hospitalization, fractures, institutionalization, and early mortality. The aim of this study was to identify the most important risk factors for FS in a group of older hospitalized patients in Poland. A total of one hundred and forty-one (78 women, 63 men) elderly patients from the Departments of Internal Medicine of the Medical University of Lodz (Poland) were recruited for this study. Frailty Instrument of the Survey of Health, Aging and Retirement in Europe (SHARE-FI), handgrip strength (HGS), depressive symptoms using the Geriatric Depression Scale (GDS), and functional ability (FA) using the Instrumental Activities of Daily Living (IADL) were assessed. According to SHARE-FI score, participants were divided into control group, frail, and pre-frail patients. Out of all 141 tested patients, FS was confirmed in 55 patients, and pre-frailty was observed in 52 patients. The occurrence of FS in the group of studied patients was related to age (p < 0.001), widowhood (p < 0.001), comorbidities (p < 0.001), heart diseases (p = 0.04), more medications taken (p < 0.001), lower FA (p < 0.001), weaker HGS, and depression (p < 0.001). The strongest positive correlations were between Share-FI score and the number of diseases (rS = 0.31), GDS (rS = 0.32), while negative correlations with IADL (rS = -0.47) and HGS (rS = -0.35). The study shows that FS is associated with age, comorbidities, number of medications taken, and widowhood. The present study has also demonstrated that FA, depression, and especially HGS are essential determinants of FS of elderly hospitalized people.

Low muscle mass and early hospital readmission post-kidney transplantation

PURPOSE

Patients exhibiting features of frailty and sarcopenia increasingly are presenting for kidney transplantation (KT) assessment. Sarcopenia, when ascertained by radiological measures, is associated with a higher transplant waiting list mortality; but studies on post-operative outcomes are lacking. We aimed to determine the clinical significance of low muscle mass in chronic kidney disease (CKD) patients subsequently receiving KT.

METHODS

We retrospectively analyzed 63 patients with Stage 4-5 CKD who, between 2012 and 2020, had undergone abdominal computed tomography (CT) scanning up to 2 years before KT. The degree of skeletal muscle loss was assessed using the total cross-sectional skeletal muscle area at the third lumbar vertebral level (L3). Cox proportional-hazards regression and Frailty models were used to identify risk factors for early hospital readmission post KT.

RESULTS

Thirty-four patients (54%) displayed low muscle mass, which was independently associated with a lower serum creatinine and phosphate, lower body mass index, lower mean muscle attenuation of the L3 cross-sectional area, and higher serum parathyroid hormone (for all p < 0.05). Deceased donor transplant recipients (n = 45) with low muscle mass demonstrated greater hospital readmissions within 30 days of KT [adjusted hazard ratio (HR) = 4.24, 95% CI 1.40-12.90, p = 0.01].

CONCLUSION

Low muscle mass is highly prevalent in the pre-transplant CKD population and is associated with increased hospital readmission in the early post-transplant period.

Sarcopenia and Frailty: Challenges in Mainstream Nephrology Practice

Sarcopenia and frailty are prevalent in the chronic kidney disease (CKD) population. Sarcopenia is characterised by the loss of muscle mass and function, while frailty is defined as a multi-system impairment associated with increased vulnerability to stressors. There is substantial overlap between the 2 conditions, particularly with regards to physical aspects: low grip strength, gait speed and low muscle mass. Both sarcopenia and frailty have been associated with a wide range of adverse health outcomes. Although there is no recommended pharmacological treatment as yet, it is widely accepted that exercise training and nutritional supplementation are the key interventions to maintain skeletal muscle mass and strength. This review aims to present a comprehensive overview of sarcopenia and frailty in patients with CKD.

Utility of Frailty Assessment in Urologic Stone Surgery: A Review of the Literature

Introduction & Objective As life expectancy continues to rise, the prevalence of frailty is also increasing. The idea of frailty and its effect on the operative patient has been previously studied, but not regularly incorporated into routine practice. We present a review on frailty metrics in the literature, validated assessment methods, and simplified screening tools, to better predict and optimize patient outcomes. Methods An online Pubmed search was conducted by 3 authors (TA, TB, MM) for all frailty, frailty assessment, and pre-operative risk assessment. Only English publications were included in the analysis. Full text analysis was then conducted by all three authors to validate the data. Results An abundance of literature was found on frailty. Even though some methods are validated as very effective for assessing frailty, they may be time consuming and require a specialist. various quick screening methods are also present, many already validated, and should be utilized by urologist more regularly. Conclusions Multiple studies demonstrate the relationship between frailty and surgical patients' outcome. Many quick, office based, validated tools to screen for frailty are described, and should be incorporated into our practice in appropriate patients. Future research is now focused on the concept of "prehabilitation" to improve patient frailty status in the pre-operative setting, and consequently operative outcomes.

Frailty and kidney transplant candidates

Frailty is a concept that has been mainly developed in geriatrics and it came from the need of identifying subjects at risk to develop complications when they faced a stressful event. Frail patients have higher risk of mortality, poor outcomes and disability, and this is independent from their age or comorbidities. Chronic kidney disease patients present with high prevalence of frailty, especially those who are in renal replacement therapy. Frail or pre-frail patients on the kidney transplant waiting list represent 20-30%, and these patients are proven to have poorer results after the transplant, which is a stressful event itself. Tools for frailty assessment, both scales or indexes, may be useful to identify which subjects might be at risk for complications after transplant, and this is necessary to adapt our clinical practice and minimize morbidity. The most used frailty scale in kidney patients is Fried scale, which is based in five phenotypic items. Besides that, knowing frail population allows potential interventions such as prehabilitation while the patient is waiting for the kidney transplant, which the aim of improving their vulnerability prior to transplant and, therefore, optimizing results after transplant. More studies are needed amongst kidney patients to improve and prevent frailty.

Effects of physical exercise on the cognition of older adults with frailty syndrome: A systematic review and meta-analysis of randomized trials

OBJECTIVES

To analyze the effects of physical exercise on the cognition of community-dwelling older adults with frailty syndrome, through randomized clinical trials.

DATA SOURCES

Articles published until March 2020 were searched in the databases Science Direct, Scopus, Web of Science, PubMed, Lilacs, Cochrane, IEEE, EMBASE, and SciELO. Search terms included frailty, aged, exercise, rehabilitation, and cognition. For the Portuguese language, equivalent terms were used.

STUDY SELECTION

Only randomized clinical trials that used physical exercise as an intervention method in community-dwelling older adults (≥ 60y.) with frailty syndrome, and which performed cognitive assessments before and after the intervention were included.

DATA EXTRACTION

Two authors performed data extraction using predefined data fields. The risk of bias of the six included studies was assessed using the PEDro scale.

DATA SYNTHESIS

In total, 4501 studies were found. After the selection process, 6 studies were included in the systematic review and 4 studies in the meta-analysis, all with a low risk of bias. The studies included 655 community-dwelling older adults with frailty syndrome. The types of intervention varied, with multicomponent physical exercise being the most frequent. The cognitive assessments were diverse, and the Mini-mental State Examination, Trail Making Test forms A and B, and Digit Span test were the most frequently applied. A meta-analysis was performed with Global Cognition and Trail Making Test forms A and B. The data from the meta-analysis showed that physical exercise improves Global Cognition (Mean Difference = 2.26; 95% CI, 0.42 - 4.09; P = 0.02) and mental flexibility (Trail Making Test B) (Mean Difference = -30.45; 95% CI; - 47.72 - -13.19; P = 0.0005).

CONCLUSION

Interventions with physical exercise promote benefits in global cognition and mental flexibility of older adults with frailty syndrome.

Effects of participatory art-based painting workshops in geriatric inpatients: results of a non-randomized open label trial

BACKGROUND

Art-based activities like painting workshops demonstrated health benefits in older individuals living in home care facilities. Few studies examined the effects of painting workshops in geriatric inpatients.

AIM

The study aims to examine whether the participation in painting workshops performed in patients admitted to a geriatric acute care ward reduced the number of medications taken daily, use of psychoactive medications, the length of stay and inhospital mortality.

METHODS

Based on a non-randomized open label trial, 79 inpatients who participated in painting workshops and 79 control inpatients were recruited in the geriatric acute care ward of the Jewish general hospital (Montreal, Quebec, Canada). Four outcomes were used: the number of medications taken daily and use of psychoactive medications the day of discharge to geriatric acute care ward, the length of hospital stay and inhospital mortality.

RESULTS

The participation in Painting workshops were associated with a lower number of medications taken daily at discharge (Coefficient of regression β =  - 1.35 with P = 0.001) and lower inhospital mortality (odd ratio (OR) = 0.09 with P = 0.031). No significant association was reported with use of psychoactive medications and length of stay.

CONCLUSION

The participation in painting workshops reduced the number of medications taken daily and incident inhospital mortality in geriatric inpatients admitted to a geriatric acute care ward, suggested a positive effect on health condition of this participatory art-based activity.

Frailty status and increased risk for falls: The role of anticholinergic burden

PURPOSE OF THE STUDY

Frailty leads to serious adverse outcomes including falls. The relationship between frailty and falls has not been evaluated in the context of the side effects of drugs with anticholinergic properties. The aim of this study was to examine the potential association of anticholinergic burden (ACB) with the risk of falls among frail older adults.

DESIGN AND METHODS

Community-dwelling older adults were consecutively selected from the geriatrics outpatient clinic. Based on a fall history in the last 12 months, the participants were grouped as fallers and non-fallers. Frailty status was assessed by Fried's phenotype method. Exposure to anticholinergic medications was estimated using the ACB scale, and the participants were classified into ACB_0 (none), ACB_1 (possible) and ACB_2+ (definite).

RESULTS

The study included 520 older adults (mean age 77.7 years, 62.7 % female), with a fall prevalence of 25.8 % 12 months past. The proportions of frailty and pre-frailty were 33.1 % and 57.4 %, respectively. After adjustment for study confounders, receiving at least 1 drug with either possible or definite anticholinergic properties was independently associated to falls in frail [OR = 3.84 (1.48-9.93), p = 0.006] and pre-frail participants [OR = 2.71 (1.25-5.89); p = 0.012], but not in robust subjects. Moreover, ACB was significantly associated with the frailty components on adjusted analysis (p's<0.05).

IMPLICATIONS

Current study showed that the use of any drugs with possible or definite anticholinergic properties was associated with an increased risk of falls in frail older adults. The results emphasize the importance of medication management with respect to fall prevention in these patients.

Prevalence and associated factors for frailty among elder patients in China: a multicentre cross-sectional study

Background

To date, most previous studies of frailty among hospitalized elderly Chinese patients have been conducted based on small samples, which cannot represent the elderly patient population. The aim of this study was to identify the prevalence of and risk factors for frailty among elderly patients in China.

Study design and setting

This cross-sectional study surveyed 9996 elderly patients from 6 tertiary-level hospitals in China. The prevalence of frailty among patients from selected wards was surveyed by trained investigators. A mixed-effects Poisson regression model was used to analyse the factors associated with frailty among elderly patients.

Results

The mean age of all subjects was 72.47 ± 5.77 years. The prevalence rate of frailty in this study was 18.02%. After adjustments were made for the confounding effect of the clustering of hospital wards, a mixed-effects Poisson regression model showed that the associated factors of frailty included the following: age (OR: 1.016, 95% CI: 1.012–1.020), BMI < 18.5 (OR: 1.248, 95% CI: 1.171–1.330), female gender (OR: 1.058, 95% CI: 1.004–1.115), ethnic minority (OR: 1.152, 95% CI: 1.073–1.236), admission to hospital by the emergency department (OR: 1.104, 95% CI: 1.030–1.184), transit from another hospital (OR: 1.159, 95% CI: 1.049–1.279), former alcohol use (OR: 1.094, 95% CI: 1.022–1.171), fall history in the past 12 months (OR: 1.257, 95% CI: 1.194–1.323), vision dysfunction (OR: 1.144, 95% CI: 1.080–1.211), cognition impairment (OR: 1.182, 95% CI: 1.130–1.237), sleeping dysfunction (OR: 1.215, 95% CI: 1.215–1.318), urinary dysfunction (OR: 1.175, 95% CI: 1.104–1.251), and defecation dysfunction (OR: 1.286, 95% CI: 1.217–1.358). The results also showed some of the following protective effects: BMI > 28 (OR: 0.897, 95% CI: 0.856–0.940); higher education level, including middle school (OR: 0.915, 95% CI: 0.857, 0.977) and diploma and above (OR: 0.891, 95% CI: 0.821, 0.966); and current alcohol use (OR: 0.869, 95% CI: 0.815, 0.927).

Conclusion

We identified a relatively high prevalence of frailty among elderly patients, and there are several associated factors among the population derived from this investigation of a large-scale, multicentre, nationally representative Chinese elderly inpatient population.

Association between frailty and life satisfaction among older people in Shandong, China: the differences in age and general self-efficacy

BACKGROUND

Frailty and other functional declines may be related to life satisfaction (LS) in the general elderly population. This study aims to investigate the association between frailty and LS among older individuals (age ≥60) and the impacts of age and general self-efficacy on the relationships.

METHODS

Using data from the 2017 Survey of the Shandong elderly Family Health Service, a cross-sectional study was conducted and 7070 older people aged 60+ were analysed. LS was measured using the Satisfaction with Life Scale. A Frailty Index (ranged 0~1) was determined as a proportion of accumulated deficits over 51 categories. General self-efficacy was measured using the Chinese version of the General Self-Efficacy Scale. Multiple weighted linear regression was used to examine possible relationships between the research variables.

RESULTS

There was a negative association between frailty and LS. A dose-response-type relationship between net income and LS was observed. The interaction between frailty and age was found to be significantly associated with LS. Frailty has a stronger negative impact on LS among the young-old (60-69 years) than among the middle-old (70-79 years) and old-old (80+ years), which suggests a protective effect of ageing on LS reduction due to frailty. However, this protective effect was observed among individuals with low and medium level self-efficacy.

CONCLUSIONS

The relationship between frailty and LS generally weaken with age. The higher level of general self-efficacy may provide a partial buffer against the negative impact of frailty on LS. Interventions that target to prevent and manage frailty should consider being prioritised among the young-old population. Development of self-efficacy could serve as an important strategy to buffer the negative effect of frailty on LS among older people.

Evaluation of clinical frailty screening in geriatric acute care

BACKGROUND

While frailty status is an attractive risk stratification tool, the evaluation of frailty in acute care can be challenging as some inpatients are unable to complete performance-based tests as part of frailty assessment and some tools may lack discriminative ability and categorize majority of cohorts as "frail". In this study, we evaluated the feasibility of frailty screening with the simple clinical frailty scale (CFS) by different clinicians, and its association with mortality and rehospitalization in a geriatric acute care setting.

METHODS

This study took place in Geriatric Medicine Department of a General Hospital in Singapore. We analysed records of 314 inpatients aged 70 years and older. At baseline, premorbid frailty was assessed using the CFS of the Canadian Study on Health and Aging. Demographic characteristics and other variables were retrieved from their medical records. Primary outcomes were mortality and rehospitalization during the 6-month follow-up. Survival analysis was used to compare the time to death and rehospitalization among CFS categories (1-4: nonfrail, 5-6: mild-moderate frail, and 7-8: severe frail).

RESULTS

CFS showed a high inter-rater reliability when used by different clinicians. In the Cox proportional hazard model controlling for age, gender, Charlson comorbidity index, modified severity of illness index, and discharge placements, severe frailty determined by CFS (HR = 2.09, 95% CI = 1.01-4.33, P = 0.047) and CFS scores (HR = 1.27, 95% CI = 1.05-1.53, P = 0.012) were significantly associated with higher mortality until 6-month postdischarge, but not rehospitalization.

CONCLUSION

Frailty status determined by CFS adds to disease severity and comorbidity in predicting short-term mortality but not rehospitalization in older inpatients who received geriatric acute care in our setting. CFS is reliable and has the potential to be incorporated into routine screening to better identify, communicate, and address frailty in the acute settings.

Comprehensive Geriatric Assessment for Frail Older People in Swedish Acute Care Settings (CGA-Swed): A Randomised Controlled Study

The aim of the study is to evaluate the effects of the Comprehensive Geriatric Assessment (CGA) for frail older people in Swedish acute hospital settings – the CGA-Swed study. In this study protocol, we present the study design, the intervention and the outcome measures as well as the baseline characteristics of the study participants. The study is a randomised controlled trial with an intervention group receiving the CGA and a control group receiving medical assessment without the CGA. Follow-ups were conducted after 1, 6 and 12 months, with dependence in activities of daily living (ADL) as the primary outcome measure. The study group consisted of frail older people (75 years and older) in need of acute medical hospital care. The study design, randomisation and process evaluation carried out were intended to ensure the quality of the study. Baseline data show that the randomisation was successful and that the sample included frail older people with high dependence in ADL and with a high comorbidity. The CGA contributed to early recognition of frail older people’s needs and ensured a care plan and follow-up. This study is expected to show positive effects on frail older people’s dependence in ADL, life satisfaction and satisfaction with health and social care.

The clinical features and prognosis of infective endocarditis in the elderly from 2007 to 2016 in a tertiary hospital in China

BACKGROUND

Infective endocarditis (IE) especially in the elderly is a serious disease, with a worse prognosis.

METHODS

A retrospective cohort study was conducted. A total of 405 patients with definite IE were divided into three groups: 205 patients under 50 years old, 141 patients between 50 and 64 years old and 59 patients over 65 years old.

RESULTS

For older patients, clinical symptoms such as fever, anemia, and heart murmur were as common as the younger patients. IE in old patients had more frequent nosocomial origin (P = 0.007) and tended to be more frequent with bad oral hygiene (p = 0.008). The most frequent isolated pathogens in the old groups was streptococci and coagulase-negative staphylococci. The old patients had a lower operation rate (40.7% vs 58.9% vs 62.4%, P = 0.012) and higher in-hospital mortality (20.3% vs 10.6% vs 8.8%, P = 0.044) compared with the younger patients. Surgical treatment was a significant predictor of one-year mortality even after adjusting for the confounders (HR = 2.45, 95% CI 1.027-10.598, P = 0.009). The one-year survival rate was higher for older patients with surgical intervention than those without (95.8% vs 68.6%, P = 0.007).

CONCLUSIONS

Older patients with IE presented with more comorbidities, bad oral hygiene, more nosocomial origin and a more severe prognosis than younger patients. Streptococci was the most frequent micro-organisms in this group. Surgery were underused in old patients and those with surgical treatment had better prognosis.

Quantifying sit-to-stand and stand-to-sit transitions in free-living environments using the activPAL thigh-worn activity monitor

PURPOSE

Standing up, sitting down and walking require considerable effort and coordination, which are crucial indicators to rehabilitation (e.g. stroke), and in older populations may indicate the onset of frailty and physical and cognitive decline. Currently, there are few reports robustly quantifying sit-to-stand and stand-to-sit transitions in free-living environments. The aim of this study was to identify and quantify these transitions using the peak velocity of sit-to-stand and stand-to-sit transitions to determine if these velocities were different in a healthy cohort and a mobility-impaired population.

METHODS

Free-living sit-to-stand and stand-to-sit acceleration data were recorded from 21 healthy volunteers and 34 stroke survivors using activPAL3™ monitors over a one-week period. Thigh inclination velocity was calculated from these accelerometer data. Maximum velocities were compared between populations.

RESULTS

A total of 10,299 and 11,392 sit-to-stand and stand-to-sit transitions were recorded in healthy volunteers and stroke survivors, respectively. Healthy volunteers had significantly higher overall mean peak velocities for both transitions compared with stroke survivors [70.7°/s ± 52.2 versus 44.2°/s ± 28.0 for sit-to-stand, P < 0.001 and 74.7°/s ± 51.8 versus 46.0°/s ± 31.9 for stand-to-sit; P < 0.001]. Mean peak velocity of transition was associated with increased variation in peak velocity across both groups.

CONCLUSION

There were significant differences in the mean peak velocity of sit-to-stand and stand-to-sit transitions between the groups. Variation in an individual's mean peak velocity may be associated with the ability to perform these transitions. This method could be used to evaluate the effectiveness of interventions following injury such as stroke, as well as monitor decline in functional ability.

Utility of minimal preparation computed tomography colonography in detecting colorectal cancer in elderly and frail patients

BACKGROUND

Colorectal cancers result in substantial morbidity and mortality to the Australian society each year. The usual investigation for bowel malignancy is optical colonoscopy (OC), with computed tomography colonography (CTC) used as an alternative investigation. The catharsis and colon insufflation associated with these investigations pose a higher risk in the elderly and frail. Risks include perforation, serum electrolyte disturbance and anaesthesia/sedation risks. Minimal preparation computed tomography colonography (MPCTC) eliminates these risks.

AIMS

To audit the accuracy of a MPCTC programme for the investigation of colonic masses in symptomatic elderly and frail patients.

METHODS

This paper audits a 6-year period of MPCTC in an Australian tertiary referral hospital. A total of 145 patients underwent MPCTC during the study period.

RESULTS

There were seven true positives, two false positives and two false negatives. Analysis of this population indicates a sensitivity of 0.78 (95% CI 0.51-1.05), specificity of 0.99 (95% CI 0.97-1.01), positive predictive value (PPV) of 0.78 (95% CI 0.51-1.05) and negative predictive value (NPV) of 0.99 (95% CI 0.97-1.01). These findings are concordant with other published studies.

CONCLUSIONS

This audit confirms that minimal preparation CT colonography is a reasonable alternative to OC and CTC in detecting colorectal cancer in symptomatic elderly and frail patients, without the procedural risks inherent in more invasive investigations. For most patients, MPCTC ruled out significant colorectal carcinoma with a high NPV.

Frailty and nutritional status in older people: the Mini Nutritional Assessment as a screening tool for the identification of frail subjects

INTRODUCTION

Frailty is a condition characterized by reduced resistance to low-level stress events, resulting from the progressive decline of multiple physiological systems observed with aging. Many factors can contribute to the pathogenesis of frailty, and nutritional status appears to play a key role. The objective of the study was to investigate the relationship between nutritional status, evaluated using Mini Nutritional Assessment (MNA), and frailty among older people.

PATIENTS AND METHODS

An observational study was carried out at the University Hospital "Tor Vergata" in Rome among patients aged 65 years or older, with or without hip fracture. The study sample included 62 patients hospitalized for a hip fracture and 50 outpatients without fracture. All subjects underwent blood sampling for laboratory assays and received a multidimensional geriatric evaluation comprising Activity of Daily Living (ADL), Instrumental Activity of Daily Living (IADL), Mini-Mental State Examination (MMSE), Geriatric Depression Scale (GDS), and MNA. Comorbidity was assessed using the Cumulative Illness Rating Scale for Geriatrics (CIRS-G). Muscle strength was measured by handgrip dynamometry, and frailty score was calculated using the Survey of Health, Ageing and Retirement in Europe-Frailty Index (SHARE-FI).

RESULTS

Approximately 38% of the study population was frail, with the prevalence of frailty being greater among hospitalized older patients. Among frail subjects, 65% were at risk of malnutrition (RMN) and 10% were malnourished. The prevalence and RMN progressively diminished in the pre-frail group and not frail group. Nutritional status was closely associated with the degree of frailty, and in a logistic regression, MNA was the best variable predicting both pre-frailty and frailty.

DISCUSSION AND CONCLUSION

Malnutrition contributes to the development of frailty. MNA can generate vital information to help identify a substantial part of both frail and pre-frail patients at low cost and care.

The relationship between different settings of medical service and incident frailty

BACKGROUND

Some studies have reported a potential association between usual source of health care and disability, but no one has explored the association with frailty, a state of early and potential reversible disability. We therefore aimed to explore the association between older persons' self-reported usual source of health care at baseline and the onset of frailty.

METHODS

Information regarding usual source of health care was captured through self-report and categorized as 1) private doctor's office, 2) public clinic, 3) Health Maintenance Organization (HMO), or 4) hospital clinic/emergency department (ED). Frailty was defined using the Study of Osteoporotic Fracture (SOF) index as the presence of at least two of the following criteria: (i) weight loss ≥5% between baseline and any subsequent follow-up visit; (ii) inability to do five chair stands; and (iii) low energy level according to the SOF definition. Multivariable Cox's regression analyses, calculating hazard ratios (HRs) with 95% confidence intervals (CIs), were undertaken.

RESULTS

Of the 4292 participants (mean age: 61.3), 58.7% were female. During the 8-year follow-up, 348 subjects (8.1% of the baseline population) developed frailty. Cox's regression analysis, adjusting for 14 potential confounders showed that, compared to those using a private doctor's office, people using a public clinic for their care had a significantly higher risk of developing frailty (HR = 1.56; 95%CI: 1.07-2.70), similar to those using HMO (HR = 1.48; 95%CI: 1.03-2.24) and those using a hospital/ED (HR = 1.76; 95%CI: 1.03-3.02).

CONCLUSION

Participants receiving health care from sources other than private doctors are at increased risk of frailty, highlighting the need for screening for frailty in these health settings.

Frailty in elderly ICU patients in Greece: a prospective, observational study

Background

Of particular interest is the study of frailty syndrome in older patients in recent years. This syndrome is characterized by weight loss and muscle mass, a change in eating habits, movement and endurance, and a decline in cognitive function. The purpose of the study was the prevalence of frailty syndrome in subjects aged 65 years who were hospitalized in an intensive care unit (ICU) in Greece.

Methods

This is a prospective, observational study. The study sample consisted of families or carers of 36 patients over 65 years of age. The study was conducted in a General Hospital in Greece, over a period of 1 year. The Clinical Frailty Scale (CFS) and the 5 criterions frailty phenotype were used. In addition, the severity of the patients with the APACHE II, SAPS II and SOFA scales was assessed. For the analysis of the data, the SPSS 19 for windows statistical package was used and more specifically descriptive statistics and correlations with parametric methods were performed.

Results

Thirty-six severely ill patients aged 65 years and over (22 women, 14 men) were studied. 25% of the patients had a positive frailty phenotype, 44% were at an early stage, while 30.6% had a frailty negative phenotype. A significant correlation between CFS and APACHE (P=0.041), age (P=0.033), sex (P=0.049) and ADL mobility index (P=0.001) was found to be significant. Concerning mortality, 36.1% of patients died in ICU, 11.1% died within the next 6 months and 38.9% were alive.

Conclusions

The findings of the study highlighted the onset of frailty syndrome in ICU patients. The objective assessment of the frailty syndrome of the seriously ill patient as well as the prognostic markers provides a clearer picture of its out-of-hospital condition and contributes to the collection of information on the outcomes of the in-hospital treatment.

Physical activity and frailty as indicators of cardiorespiratory reserve and predictors of surgical prognosis: General and digestive surgery population characterization

INTRODUCTION

Frailty and low physical activity and cardiorespiratory reserve are related to higher perioperative morbimortality. The crucial step in improving the prognosis is to implement specific measures to optimize these aspects. It is critical to know the magnitude of the problem in order to implement preoperative optimization programmes.

OBJECTIVE

To characterize surgical population in a university hospital.

METHODS

All patients undergoing preoperative evaluation for abdominal surgery with admission were prospectively included during a 3-month period. Level of physical activity, functional capacity, frailty and emotional state were assessed using score tests. Additionally, physical condition was evaluated using 5 Times Sit-to-Stand Test. Demographic, clinical and surgical data were collected.

RESULTS

One hundred and forty patients were included (60±15yr-old, 56% male, 25% ASA III or IV). Forty-nine percent of patients were proposed for oncologic surgery and 13% of which had received neoadjuvant treatment. Seventy percent of patients presented a low functional capacity and were sedentary. Eighteen percent of patients were considered frail and more than 50% completed the 5 Times Sit-to-Stand Test at a higher time than the reference values adjusted to age and sex. Advanced age, ASA III/IV, sedentarism, frailty and a high level of anxiety and depression were related to a lower functional capacity.

CONCLUSIONS

The surgical population of our area has a low functional reserve and a high index of sedentary lifestyle and frailty, predictors of postoperative morbidity. It is mandatory to implement preoperative measures to identify population at risk and prehabilitation programmes, considered highly promising preventive interventions towards improving surgical outcome.

The GesTIO protocol experience: safety of a standardized order set for subcutaneous insulin regimen in elderly hospitalized patients

BACKGROUNDS

In non-critical hospitalized patients with diabetes mellitus, guidelines suggest subcutaneous insulin therapy with basal-bolus regimen, even in old and vulnerable inpatients.

AIM

To evaluate safety, efficacy, and benefit on clinical management of the GesTIO protocol, a set of subcutaneous insulin administration rules, in old and vulnerable non-ICU inpatients.

METHODS

Retrospective, observational study. Patients admitted to Geriatric Clinic of Padua were studied. 88 patients matched the inclusion criteria: type 2 diabetes or hospital-related hyperglycemia, ≥65 years, regular measurements of capillary glycemia, and basal-bolus subcutaneous insulin regimen managed by "GesTIO protocol" for five consecutive days.

MAIN OUTCOME MEASURES

ratio of patients with blood glucose (BG) <3.9 mmol/l; number of BG per patient in target range (5-11.1 mmol/l); daily mean BG; and calls to physicians for adjusting insulin therapy.

RESULTS

Mean age was 82 ± 7 years. 9.1% patients experienced mild hypoglycaemia, and no severe hypoglycaemia was reported. The median number of BG per patients in target range increased from 2.0 ± 2 to 3.0 ± 2 (p < 0.001). The daily mean BG decreased from 11.06 ± 3.03 to 9.64 ± 2.58 mmol/l (-12.8%, p < 0.005). The mean number of calls to physicians per patient decreased from 0.83 to 0.45 (p < 0.05).

CONCLUSIONS

Treatment with GesTIO protocol allows a safe and effective treatment even in very old and vulnerable inpatients with a faster management insulin therapy.

Operationalizing a frailty index using routine blood and urine tests

Background

Uncomplicated frailty instruments are desirable for use in a busy clinical setting. The aim of this study was to operationalize a frailty index (FI) from routine blood and urine tests, and to evaluate the properties of this FI compared to other frailty instruments.

Materials and methods

We conducted a secondary analysis of a prospective cohort study on 306 patients aged ≥65 years hospitalized on geriatric wards. An FI comprising 22 routine blood parameters and one standard urine parameter (FI-Lab), a 50-item FI based on a comprehensive geriatric assessment (FI-CGA), a combined FI (FI-combined [items from the FI-Lab + others from the FI-CGA]), the Clinical Frailty Scale, rule-based frailty definition, and frailty phenotype were operationalized from data obtained during patients’ hospital stays (ie, before discharge [baseline examination]). Follow-up data were obtained up to 1 year after the baseline examination.

Results

The mean FI-Lab score was 0.34±15, with an upper limit of 0.74. The FI-Lab was correlated with all the other frailty instruments (all P<0.001). The FI-Lab revealed an area under the receiver-operating characteristic curve (AUC) for 6-month and 1-year mortality of 0.765 (0.694–0.836) and 0.769 (0.706–0.833), respectively (all P<0.001). Each 0.01 increment in FI-Lab increased the risk (adjusted for age and sex) for 6-month and 1-year mortality by 7.2% and 7.1%, respectively (all adjusted P<0.001). When any of the other FIs (except the FI-combined) were also included in the models, each 0.01 increment in FI-Lab score was associated with an increase in the risk of 6-month and 1-year mortality by 4.1%–5.4% (all adjusted P<0.001).

Conclusion

The FI-Lab showed key characteristics of an FI. The FI-Lab can be applied as a single frailty measure or in combination with/in addition to other frailty instruments.

How to lower postoperative complications after radical cystectomy - a review

Introduction

Lowering morbidity and mortality after RC is subject of considerable interest. Lately, many evidence-based data on improvements in operative technique, anesthetic management, and patient care have been published.

In this article, we present a review of literature on how to lower postoperative complications after RC.

Material and methods

The Medline, and Web of Science databases were searched without a time limit on February 2016 using the terms ‘cystectomy’ in conjunction with ‘radical’, ‘bladder cancer’, ‘complications’ or ‘management’. Boolean operators (NOT, AND, OR) were also used in succession to narrow and broaden the search. The search was limited to the English, Polish and Spanish literature.

Results

Many complications may be avoided by appropriate patient selection and meticulous introduction of care protocols.

Conclusions

RC as treatment free of complications, even in the hands of an experienced urologist, does not exist. A large number of complications are acceptable in the name of good long-term results. Optimum results are possible with proper surgical technique, good patients and urinary diversion selection and proper patient management in the pre-, peri, and postoperative period.

Frailty and chronic kidney disease: A systematic review

OBJECTIVE

Frailty is associated with increased vulnerability to poor health. There is growing interest in understanding the association between frailty and chronic kidney disease (CKD). This systematic review explored how frailty is measured in patients with CKD and the association between frailty and adverse outcomes across different stages of renal impairment.

STUDY DESIGN

Systematic analysis of peer reviewed articles.

DATA SOURCES

Pubmed, Medline, Web of Science and Cochrane were used to identify the articles.

DATA SYNTHESIS

Articles published before the 17th of September 2016, that measured frailty in patients with CKD was eligible for the systematic review. Two independent researchers assessed the eligibility of the articles. Quality of the articles was assessed using the Epidemiological Appraisal Instrument.

RESULTS

The literature search yielded 540 articles, of which 32 met the study criteria and were included in the review (n=36,076, age range: 50-83 years). Twenty-three (72%) studies used or adapted the Fried phenotype to measure frailty. The prevalence of frailty ranged from 7% in community-dwellers (CKD Stages 1-4) to 73% in a cohort of patients on haemodialysis. The incidence of frailty increased with reduced glomerular filtration rate. Frailty was associated with an increased risk of mortality and hospitalization.

CONCLUSION

Frailty is prevalent in patients with CKD and it is associated with an increased risk of adverse health outcomes. There are differences in the methods used to assess frailty and this hinders comparisons between studies.

Minimizing bleeding risk in patients receiving direct oral anticoagulants for stroke prevention

Many primary care physicians are wary about using direct oral anticoagulants (DOACs) in patients with nonvalvular atrial fibrillation (AF). Factors such as comorbidities, concomitant medications, and alcohol misuse increase concerns over bleeding risk, especially in elderly and frail patients with AF. This article discusses strategies to minimize the risk of major bleeding events in patients with AF who may benefit from oral anticoagulant therapy for stroke prevention. The potential benefits of the DOACs compared with vitamin K antagonists, in terms of a lower risk of intracranial hemorrhage, are discussed, together with the identification of reversible risk factors for bleeding and correct dose selection of the DOACs based on a patient’s characteristics and concomitant medications. Current bleeding management strategies, including the new reversal agents for the DOACs and the prevention of bleeding during preoperative anticoagulation treatment, in addition to health care resource use associated with anticoagulation treatment and bleeding, are also discussed. Implementing a structured approach at an individual patient level will minimize the overall risk of bleeding and should increase physician confidence in using the DOACs for stroke prevention in their patients with nonvalvular AF.

Feasibility and construct validity of a Frailty index for patients with chronic kidney disease

AIM

To determine whether the frailty status of patients with chronic kidney disease (CKD) can be measured using a Frailty index (FI).

METHODS

One hundred and eleven attending a nephrology clinic were approached to complete a one-page questionnaire evaluating cognitive, psychological and functional status. Data were coded as deficits, summed and divided by the total number of deficits considered, to derive an FI-CKD.

RESULTS

One hundred and ten (mean age 65.2 years) agreed to participate and assessments took approximately 10 minutes to complete. Mean FI-CKD was 0.25 (SD 0.12). The FI-CKD increased with age at 3% per year, correlated with a modified Fried phenotype (P < 0.001) and increased significantly across CKD stages (P = 0.04).

CONCLUSIONS

The FI-CKD is feasible in the outpatient setting and has good construct validity. The greater granularity of a continuous measure has the potential to inform decision-making regarding appropriate interventions for patients at the 'frail' end of the health spectrum.

Premature and preventable deaths in frail, older people: a new perspective

The concept and potential implications of a premature death of an older person are under-recognised and misunderstood by society. Clinical, forensic and public health practitioners need to redress this gap to prepare society better for a future where an increasing proportion of the population are vulnerable older people. Reliable and valid information is paramount for understanding how many older people have premature, preventable deaths, with implications for aged care services, health-care expenditure, quality and safety, and human rights. Our aim is to: (a) provide discourse on the limitations and challenges to the use of the concepts ‘premature’ and ‘preventable’ deaths, examining the situation for nursing home residents; and (b) propose the use of a novel classification system of ‘treated’, ‘un-treated’ and ‘untreatable’ causes of death that is more sophisticated and reflects the demographic reality of our ageing population. Accepting that preventable, premature deaths may happen to older people and adopting a new classification is a novel approach that has considerable benefits for health and life care of older persons. Improved assessment of the quality of care provided, including identification of health or life care practices that are unsafe or deleterious, can be identified and addressed.

The Charlson Comorbidity Index (CCI) as a Mortality Predictor after Surgery in Elderly Patients

The increasing range of surgery in elderly patients reflects the changing demography where in the next 10 years one quarter of the population will be 65 years of age or older. There is presently no consensus concerning the optimal predictive markers for postoperative morbidity and mortality after surgery in older patients with an appreciation that physical frailty is more important than chronological age. In this retrospective analysis, we have compared the impact of age and the calculated preoperative Charlson Comorbidity Index (CCI) on early (30-day) and late (one-year) mortality in a group of patients >75 years of age dividing them into an “older old” cohort (75–84 years of age, Group A) and an “oldest old” group (≥85 years of age, Group B). Increased age was associated with a higher death rate after emergency surgery, with late deaths after elective surgery exceeding those after emergency operations. A higher mean CCI was noted in both age groups in early nonsurvivors after both elective and emergency surgery with a more significant effect of the preoperative CCI than chronological age for the prediction of late postoperative death for both groups after elective and emergency operations. Although the CCI was not designed to predict perioperative mortality in surgical cohorts, it correlates with a greater risk than age for perioperative death in the elderly.

Managing infective endocarditis in the elderly: new issues for an old disease

The incidence of infective endocarditis (IE) rises in industrialized countries. Older people are more affected by this severe disease, notably because of the increasing number of invasive procedures and intracardiac devices implanted in these patients. Peculiar clinical and echocardiographic features, microorganisms involved, and prognosis of IE in elderly have been underlined in several studies. Additionally, elderly population appears quite heterogeneous, from healthy people without past medical history to patients with multiple diseases or who are even bedridden. However, the management of IE in this population has been poorly explored, and international guidelines do not recommend adapting the therapeutic strategy to the patient's functional status and comorbidities. Yet, if IE should be treated according to current recommendations in the healthiest patients, concerns may rise for older patients who suffer from several chronic diseases, especially renal failure, and are on polypharmacy. Treating frailest patients with high-dose intravenous antibiotics during a prolonged hospital stay as recommended for younger patients could also expose them to functional decline and toxic effect. Likewise, the place of surgery according to the aging characteristics of each patient is unclear. The aim of this article is to review the recent data on epidemiology of IE and its peculiarities in the elderly. Then, its management and various therapeutic approaches that can be considered according to and beyond guidelines depending on patient comorbidities and frailty are discussed.

Risk Factors for Emergency Department Short Time Readmission in Stratified Population

Background. Emergency department (ED) readmissions are considered an indicator of healthcare quality that is particularly relevant in older adults. The primary objective of this study was to identify key factors for predicting patients returning to the ED within 30 days of being discharged. Methods. We analysed patients who attended our ED in June 2014, stratified into four groups based on the Kaiser pyramid. We collected data on more than 100 variables per case including demographic and clinical characteristics and drug treatments. We identified the variables with the highest discriminating power to predict ED readmission and constructed classifiers using machine learning methods to provide predictions. Results. Classifier performance distinguishing between patients who were and were not readmitted (within 30 days), in terms of average accuracy (AC). The variables with the greatest discriminating power were age, comorbidity, reasons for consultation, social factors, and drug treatments. Conclusions. It is possible to predict readmissions in stratified groups with high accuracy and to identify the most important factors influencing the event. Therefore, it will be possible to develop interventions to improve the quality of care provided to ED patients.

Analysis of Rockwood et Al's Clinical Frailty Scale and Fried et Al's Frailty Phenotype as Predictors of Mortality and Other Clinical Outcomes in Older Patients Who Were Admitted to a Geriatric Ward

OBJECTIVES

There are few data regarding the accuracy of short frailty tools as predictors of mortality and other clinical outcomes of older patients admitted to a geriatric ward. We therefore analyzed the accuracy of Rockwood et al's Clinical Frailty Scale and an easy and quick to perform operationalization of Fried et al's frailty phenotype, as predictors of mortality and other clinical outcomes in our cohort of patients.

DESIGN

Prospective analysis with a follow-up period of 6 months.

SETTING AND PARTICIPANTS

307 patients who were 65 years of age or older were included in the study. The patients were assessed in terms of the two frailty measures during their stay in a geriatric ward.

RESULTS

The Clinical Frailty Scale and the frailty phenotype were both suitable for differentiating between patients who died due to any cause from those who survived during follow-up (primary outcome) (area under the ROC curves (AUC) values 0.867 (95% CI 0.807-0.926), p<0.001 and 0.754 (95% CI 0.688-0.821), p<0.001, respectively). Regarding the secondary outcomes: 1. unplanned admission to hospital and 2. a fall during follow-up, the Clinical Frailty Scale discriminated or tended to discriminate between patients to whom these criteria applied and those to whom they did not (AUC=0.569 (95% CI 0.502-0.636), p=0.046 and AUC=0.574 (95% CI 0.501-0.647), p=0.071, respectively). The frailty phenotype did not show such a differentiation when applied to secondary outcomes (AUC=0.500 (95% CI 0.432-0.568), p=0.994 and AUC=0.518 (95% CI 0.439-0.598), p=0.658, respectively).

CONCLUSIONS

Both short frailty instruments are suitable predictors of mortality in older patients who were admitted to a geriatric ward. The Clinical Frailty Scale, but not the frailty phenotype, predicted at least some of the secondary outcomes, i.e., the outcome unplanned admission to hospital during follow-up.

Systematic review of clinical practice guidelines recommendations about primary cardiovascular disease prevention for older adults

BACKGROUND

Clinical care for older adults is complex and represents a growing problem. They are a diverse patient group with varying needs, frequent presence of multiple comorbidities, and are more susceptible to treatment harms. Thus Clinical Practice Guidelines (CPGs) need to carefully consider older adults in order to guide clinicians. We reviewed CPG recommendations for primary cardiovascular disease (CVD) prevention and examined the extent to which CPGs address issues important for older people identified in the literature.

METHODS

We searched: 1) two systematic reviews on CPGs for CVD prevention and 2) the National CPG Clearinghouse, G-I-N International CPG Library and Trip databases for CPGs for CVD prevention, hypertension and cholesterol. We conducted our search between April and December 2013. We excluded CPGs for diabetes, chronic kidney disease, HIV, lifestyle, general screening/prevention, and pregnant or pediatric populations. Three authors independently screened citations for inclusion and extracted data. The primary outcomes were presence and extent of recommendations for older people including discussion of: (1) available evidence, (2) barriers to implementation of the CPG, and (3) tailoring management for this group.

RESULTS

We found 47 eligible CPGs. There was no mention of older people in 4 (9 %) of the CPGs. Benefits were discussed more frequently than harms. Twenty-three CPGs (49 %) discussed evidence about potential benefits and 18 (38 %) discussed potential harms of CVD prevention in older people. Most CPGs addressed one or more barriers to implementation, often as a short statement. Although 27 CPGs (58 %) mentioned tailoring management to the older patient context (e.g. comorbidities), concrete guidance was rare.

CONCLUSION

Although most CVD prevention CPGs mention the older population to some extent, the information provided is vague and very limited. Older adults represent a growing proportion of the population. Guideline developers must ensure they consider older patients' needs and provide appropriate advice to clinicians in order to support high quality care for this group. CPGs should at a minimum address the available evidence about CVD prevention for older people, and acknowledge the importance of patient involvement.

Redefining the Economics of Geriatric Orthopedics

Introduction:

The heath care system in the United States is in the midst of a transition, in large part to help accommodate an older and more medically complex population. Central to the current evolution is the reassessment of value based on the cost utility of a particular procedure compared to alternatives. The existing contribution of geriatric orthopedics to the societal burden of disease is substantial, and literature focusing on the economic value of treating elderly populations with musculoskeletal injuries is growing.

Materials and Methods:

A literature review of peer-reviewed publications and abstracts related to the cost-effectiveness of treating geriatric patients with orthopedic injuries was carried out.

Results:

In our review, we demonstrate that while cost-utility studies generally demonstrate net society savings for most orthopedic procedures, geriatric populations often contribute to negative net society savings due to decreased working years and lower salaries while in the workforce. However, the incremental cost-effective ratio for operative intervention has been shown to be below the financial willingness to treat threshold for common procedures including joint replacement surgery of the knee (ICER US$8551), hip (ICER US$17 115), and shoulder (CE US$957) as well as for spinal procedures and repair of torn rotator cuffs (ICER US$12 024). We also discuss the current trends directed toward improving institutional value and highlight important complementary next steps to help overcome the growing demands of an older, more active society.

Conclusion:

The geriatric population places a significant burden on the health care system. However, studies have shown that treating this demographic for orthopedic-related injuries is cost effective and profitable for providers under certain scenarios.

Nature and extent of external-cause deaths of nursing home residents in Victoria, Australia

OBJECTIVES

To describe the nature and extent of external-cause deaths of residents of nursing homes in Victoria, Australia.

DESIGN

A retrospective cohort study of all decedents using routinely collected data contained within the National Coronial Information System.

SETTING

Accredited nursing homes in Victoria.

PARTICIPANTS

Nursing home residents who had died from external causes and whose deaths were reported to the Coroners Court between July 1, 2000, and December 31, 2012.

MEASUREMENTS

Basic descriptive analysis was conducted to measure frequencies and proportion of exposures within each outcome group, and rates were calculated using population data.

RESULTS

One thousand two hundred ninety-six external cause deaths of nursing home residents were identified. Deaths were due to falls (n=1,155, 89.1%), choking (n=89, 6.9%), suicide (n=17, 1.3%), complications of clinical care (n=8, 0.6%) and resident-on-resident assault (n=7, 0.5%). Deaths occurred more frequently in women (n=814, 62.8%), in keeping with the sex distribution in nursing homes, and residents aged 85 and older (n=923, 71.2%). The number of inquests held to investigate a death as a matter of public interest was small (n=24, 1.9%).

CONCLUSION

A significant proportion of nursing home resident deaths are from external causes and are potentially preventable. A shift in community attitudes is required toward an understanding that premature death of a resident from injury is not a natural part of life.

The concept of frailty in geriatric chronic kidney disease (CKD) patients

Frailty, which is a geriatric syndrome characterized by weakness, impaired mobility, balance, and minimal reserve, is highly prevalent in the renal population. While distinct from disability and comorbidity, some of the simplest and most clinically useful scales incorporate both the burden of medical symptoms and the effect on functional independence into the evaluation of frailty. In the renal population, the frailty phenotype has been shown to correlate with important outcomes such as hospitalization and survival. Further work is required to establish if the presence of, and the treatments used for renal disease, promote the sick role and decreased participation in exercise with overestimation of frailty or if the frailty phenotype identifies people who may benefit from rehabilitation and other interventions.

[Frailty syndrome: an old new friend]

Frailty syndrome is defined as extreme stress vulnerability and decreased potential to adapt. The elderly and chronically ill patients are affected mostly. This condition increases the risk of adverse health outcomes as infections, falls, delirium, institutionalization, progression of comorbidities and mortality. The pathophysiological mechanism is a complex immune and neuroendocrine dysregulation. According to the phenotype model, frailty presents when three of the followings occur: weakness, exhaustion, slowness, weight loss and decreased activity, while cumulative model counts the number of health deficits. Aging, frailty, dementia and depression are independent clinical entities; they may present separately but may also potentiate each other. Hence most of the frailty scales assess the physical, mental and social dimensions as well. Mild or moderate frailty is potentially reversible with an individualised caring plan. Given short, easy-to-use screening tools, risk groups can be identified in the primary care and referred to a specialised team for further treatment. Here the authors summarise the literature of a re-discovered, current clinical phenomena, frailty syndrome, focusing on the practical issues in primary care.

Frailty in an Older Inpatient Population

Objective: To evaluate the impact of frailty, measured using the Canadian Study of Health and Aging Clinical Frailty Scale, on outcomes of older people hospitalized with acute illness. Method: Consecutive patients were randomly allocated to a model development sample or a model validation sample. Multivariate analyses were used to model in-hospital mortality, new nursing home placement, and length of stay. Variables selected in the development samples were tested in the validation samples. Results: The mean age of all 2,125 patients was 82.9 years. Most (93.6%) were admitted through the emergency department. Frailty predicted in-hospital mortality (odds ratio [OR] = 2.97 [2.11, 4.17]), new nursing home placement (OR = 1.60 [1.14, 2.24]), and length of hospital stay (hazard ratio = 0.87 [0.81, 0.93]). Discussion: Frailty is a strong predictor of adverse outcomes in older people hospitalized with acute illness. An increased awareness of its impact may alert clinicians to screen for frailty.

A systematic review of prescribing criteria to evaluate appropriateness of medications in frail older people

This study systematically reviews the published literature regarding inappropriate prescribing in frail individuals aged at least 65 years. Twenty-five of 466 identified studies met the inclusion criteria. All papers measured some surrogate indicators of frailty, such as performance-based tests, cognitive function and functional dependency. Beers criteria were used in 20 studies (74%) to evaluate inappropriate medication use and 36% (9/25) studies used more than one criterion. The prevalence of inappropriate medications ranged widely from 11 to 92%. Only a few studies reported the relationship between potentially inappropriate medication use and surrogate measures of frailty. These diverse findings indicate the need for a standardized measure for assessing appropriateness of medication in frail older individuals. Prescribing tools should address both medication and patient-related factors such as life expectancy and functional status to minimize inappropriate prescribing in frail individuals.

A pragmatic triage system to reduce length of stay in medical emergency admission: feasibility study and health economic analysis

BACKGROUND

Departments of Internal Medicine tend to treat patients on a first come first served basis. The effects of using triage systems are not known.

METHODS

We studied a cohort in an Acute Medical Unit (AMU). A computer-assisted triage system using acute physiology, pre-existing illness and mobility identified five distinct risk categories. Management of the category of very low risk patients was streamlined by a dedicated Navigator. Main outcome parameters were length of hospital stay (LOS) and overall costs. Results were adjusted for the degree of frailty as measured by the Clinical Frailty Scale (CFS). A six month baseline phase and intervention phase were compared.

RESULTS

6764 patients were included: 3084 in the baseline and 3680 in the intervention phase. Patients with very low risk of death accounted for 40% of the cohort. The LOS of the 1489 patients with very low risk of death in the intervention group was reduced by a mean of 1.85days if compared with the 1276 patients with very low risk in the baseline cohort. This was true even after adjustment for frailty. Over the six month period the cost of care was reduced by £250,158 in very low patients with no increase in readmissions or 30day mortality.

CONCLUSIONS

Implementation of an advanced triage system had a measurable impact on cost of care for patients with very low risk of death. Patients were safely discharged earlier to their own home and the intervention was cost-effective.

Quality indicators for hip fracture patients: a scoping review protocol

INTRODUCTION

Hip fractures are a significant cause of morbidity and mortality and care of hip fracture patients places a heavy burden on healthcare systems due to prolonged recovery time. Measuring quality of care delivered to hip fracture patients is important to help target efforts to improve care for patients and efficiency of the health system. The purpose of this study is to synthesise the evidence surrounding quality of care indicators for patients who have sustained a hip fracture. Using a scoping review methodology, the research question that will be addressed is: "What patient, institutional, and system-level indicators are currently in use or proposed for measuring quality of care across the continuum for individuals following a hip fracture?".

METHODS AND ANALYSIS

We will employ the methodological frameworks used by Arksey and O'Malley and Levac et al. The synthesis will be limited to quality of care indicators for individuals who suffered low trauma hip fracture. All English peer-reviewed studies published from the year 2000-most recent will be included. Literature search strategies will be developed using medical subject headings and text words related to hip fracture quality indicators and the search will be peer-reviewed. Numerous electronic databases will be searched. Two reviewers will independently screen titles and abstracts for inclusion, followed by screening of the full text of potentially relevant articles to determine final inclusion. Abstracted data will include study characteristics and indicator definitions.

DISSEMINATION

To improve quality of care for patients and create a more efficient healthcare system, mechanisms for the measurement of quality of care are required. The implementation of quality of care indicators enables stakeholders to target areas for improvement in service delivery. Knowledge translation activities will occur throughout the review with dissemination of the project goals and findings to local, national, and international stakeholders.

Psychosocial factors modify the association of frailty with adverse outcomes: a prospective study of hospitalised older people

BACKGROUND

Frailty increases the risk of adverse outcomes in older people. The impact of psychosocial factors on frailty and adverse clinical outcomes associated with frailty has not yet been examined in the hospital setting. The aims of this study were to: i) investigate the association between psychosocial factors and frailty, and ii) to establish whether psychosocial factors impact on the association between frailty and adverse outcomes.

METHODS

Data was collected from a Geriatric Evaluation and Management Unit (GEMU) in Australia. Frailty was identified using Fried's frailty criteria. Psychosocial factors included wellbeing, sense of control (mastery), social activities, home/neighbourhood satisfaction, social relationships, anxiety and depression. Outcome measures were: mortality at 12 months, long length of GEMU stay (LOS), 1-month emergency rehospitalisation, and a higher level of care needed on discharge. Covariates adjusted for were age, gender and comorbidity.

RESULTS

The mean (SD) age of participants (n = 172) at admission was 85.2 (6.4) years, with 129 (75%) female patients. 96 (56%) patients were classified as frail, with 64 (37%) pre-frail and 12 (7%) robust. Frail patients had an increased likelihood of 12-month mortality (HR, 95% CI = 3.16, 1.36-7.33), discharge to a higher level of care (OR, 95% CI = 2.40, 1.21-4.78), long LOS (OR, 95% CI = 2.04, 1.07-3.88) and 1-month emergency rehospitalisation (OR, 95% CI = 2.53, 1.10-5.82). Psychosocial factors associated with frailty included poor wellbeing, anxiety, depression, and a low sense of control. Several psychosocial factors increased the likelihood of adverse outcomes associated with frailty, including anxiety and low ratings for: wellbeing, sense of control, social activities and home/neighbourhood satisfaction.

CONCLUSIONS

Our results indicate that frail older adults with low psychosocial resources had an elevated risk of mortality, discharge to higher level care, long LOS and rehospitalisation. Consideration of psychosocial factors in comprehensive geriatric assessments will assist in patient care planning.
