Ability of 3 Frailty Measures to Predict Short-Term Outcomes in Older Patients Admitted for Post-Acute Inpatient Rehabilitation

ObjectivesTo evaluate the ability of 3 commonly used frailty measures to predict short-term clinical outcomes in older patients admitted for post-acute inpatient rehabilitation.DesignObservational cohort study.Setting and ParticipantsConsecutive patients (n = 207) admitted to a geriatric inpatient rehabilitation facility.MethodsFrailty on admission was assessed using a frailty index, the physical frailty phenotype, and the Clinical Frailty Scale (CFS). Predictive capacity of the frailty instruments was analyzed for (1) nonhome discharge, (2) readmission to acute care, (3) functional decline, and (4) prolonged length of stay, using multivariate logistic regression models and receiver operating characteristic (ROC) curves.ResultsThe number of patients classified as frail was 91 (44.0%) with the frailty index, 134 (64.7%) using the frailty phenotype, and 151 (73.0%) with the CFS. The 3 frailty measures revealed acceptable discriminatory accuracy for nonhome discharge (area under the curve ≥ 0.7) but differed in their predictive ability: the adjusted odds ratio (OR) for nonhome discharge was highest for the CFS [6.2, 95% confidence interval (CI) 1.8-21.1], compared to the frailty index (4.1, 95% CI 2.0-8.4) and the frailty phenotype (OR 2.9, 95% CI 1.2-6.6). For the other outcomes, discriminatory accuracy based on ROC tended to be lower and predictive ability varied according to frailty measure. Readmission to acute care from inpatient rehabilitation was predicted by all instruments, most pronounced by the frailty phenotype (OR 5.4, 95% CI 1.6-18.8) and the frailty index (OR 2.5, 95% CI 1.1-5.6), and less so by the CFS (OR 1.4, 95% CI 0.5-3.8).Conclusions and ImplicationsFrailty measures may contribute to improved prediction of outcomes in geriatric inpatient rehabilitation. The choice of the instrument may depend on the individual outcome of interest and the corresponding discriminatory ability of the frailty measure.     

Predictors for the Transitions of Poor Clinical Outcomes Among Geriatric Rehabilitation Inpatients

ObjectiveTo investigate the associations of morbidity burden and frailty with the transitions between functional decline, institutionalization, and mortality.DesignREStORing health of acutely unwell adulTs (RESORT) is an ongoing observational, longitudinal inception cohort and commenced on October 15, 2017. Consented patients were followed for 3 months postdischarge.Setting and ParticipantsConsecutive geriatric rehabilitation inpatients admitted to geriatric rehabilitation wards.MethodsPatients’ morbidity burden was assessed at admission using the Charlson Comorbidity Index (CCI) and Cumulative Illness Rating Scale (CIRS). Frailty was assessed using the Clinical Frailty Scale (CFS) and modified Frailty Index based on laboratory tests (mFI-lab). A multistate model was applied at 4 time points: 2 weeks preadmission, admission, and discharge from geriatric rehabilitation and 3 months postdischarge, with the following outcomes: functional decline, institutionalization, and mortality. Cox proportional hazards regression was applied to investigate the associations of morbidity burden and frailty with the transitions between outcomes.ResultsThe 1890 included inpatients had a median age of 83.4 (77.6-88.4) years, and 56.3% were female. A higher CCI score was associated with a greater risk of transitions from preadmission and declined functional performance to mortality [hazard ratio (HR) 1.28, 95% CI 1.03-1.59; HR 1.32, 95% CI 1.04-1.67]. A higher CIRS score was associated with a higher risk of not recovering from functional decline (HR 0.80, 95% CI 0.69-0.93). A higher CFS score was associated with a greater risk of transitions from preadmission and declined functional performance to institutionalization (HR 1.28, 95% CI 1.10-1.49; HR 1.23, 95% CI 1.04-1.44) and mortality (HR 1.12, 95% CI 1.01-1.33; HR 1.11, 95% CI 1.003-1.31). The mFI-lab was not associated with any of the transitions. None of the morbidity measures or frailty assessment tools were associated with the transitions from institutionalization to other outcomes.Conclusions and ImplicationsThis study demonstrates that greater frailty severity, assessed using the CFS, is a significant risk factor for poor clinical outcomes and demonstrates the importance of implementing it in the geriatric rehabilitation setting.     

Associations of Handgrip Strength and Handgrip Strength Asymmetry With Depression in the Elderly in Korea: A Cross-sectional Study

ObjectivesRecent studies have suggested that assessing handgrip strength (HGS) asymmetry together with HGS may be helpful for evaluating problems in geriatric patients. This study aimed to identify whether HGS asymmetry, weakness, or both were associated with depression in Korean older adults.MethodsThis study included 4274 subjects from the sixth and seventh Korea National Health and Nutrition Examination Survey. Depression was measured using the Patient Health Questionnaire-9. The maximum HGS of the dominant hand was used as a representative value. HGS symmetry was categorized by the ratio of the HGS of the dominant hand to that of non-dominant hand. The odds ratio (OR) for depression was calculated according to the HGS and its symmetry.ResultsIn total, 240 (12.5%) men and 534 (22.7%) women had depression. HGS or HGS asymmetry showed no statistically significant associations with depression in elderly men. Elevated odds of depression were observed in elderly women with low HGS (OR, 1.93; 95% confidence interval [CI], 1.33 to 2.81) or prominent HGS asymmetry (OR, 1.46; 95% CI, 1.02 to 2.08). There was a positive additive interaction between asymmetric HGS and weakness, as women with low and prominently asymmetric HGS showed higher odds of depression (OR, 3.77; 95% CI, 2.16 to 6.59) than women with high and symmetric HGS.ConclusionsDepression in elderly Korean women was associated with both low and asymmetric HGS. Our findings support the potential value of HGS asymmetry as an indicator of HGS.     

Combinations of Sarcopenia Diagnostic Criteria by Asian Working Group of Sarcopenia (AWGS) 2019 Guideline and Incident Adverse Health Outcomes in Community-Dwelling Older Adults

ObjectivesThis study aimed to investigate the association between combinations of sarcopenia criteria by the Asian Working Group of Sarcopenia (AWGS) 2019 guideline and incident adverse health outcomes.DesignLongitudinal analyses of a cohort study.Setting and ParticipantsWe conducted prospective 2-year follow-up analyses (N = 1959) among community-dwelling older adults enrolled in the nationwide Korean Frailty and Aging Cohort Study (KFACS).MethodsFrom the KFACS, 1959 older adults (52.8% women; mean age = 75.9 ± 3.9 years) who underwent assessments for appendicular skeletal mass using dual-energy X-ray absorptiometry, handgrip strength, usual gait speed, 5-times sit-to-stand test, and Short Physical Performance Battery (SPPB) at baseline were included. Participants with each adverse health outcome [mobility disability, falls, and instrumental activities of daily living (IADL) disabilities] at baseline were excluded for each corresponding analysis. Multivariable logistic regression was performed to examine whether sarcopenia defined by different diagnostic criteria was associated with incident adverse health outcomes after 2 years.ResultsA total of 444 participants (22.7%) were diagnosed with sarcopenia as defined by AWGS 2019. In the multivariable analysis, sarcopenia defined as both low muscle mass and low physical performance increased the risk of mobility disability (OR 2.14, 95% CI 1.35-3.38) and falls (1.74, 95% CI 1.21-2.49). Only the criterion defined as both low muscle mass and physical performance using the SPPB increased the risk of falls with fracture (2.53, 95% CI 1.01-6.35) and IADL disabilities (2.77, 95% CI 1.21-6.33). However, sarcopenia defined as both low muscle mass and low hand grip strength showed no associations with the incidence of any of the adverse health outcomes.Conclusions and ImplicationsOur study suggests that the predictive value of adverse health outcomes for community-dwelling older adults is better when diagnosed with sarcopenia based on low muscle mass and physical performance. Furthermore, using the SPPB as a diagnostic tool for low physical performance may improve the predictive validity for falls with fracture and IADL disability. Our findings may be helpful for the early detection of individuals with sarcopenia who have a higher risk of adverse health outcomes.     

Urinary Incontinence and Indwelling Urinary Catheters in Acutely Admitted Elderly Patients: Relationship With Mortality,Institutionalization, and Functional Decline

ObjectivesTo study differences in functional status at admission in acutely hospitalized elderly patients with urinary incontinence, a catheter, or without a catheter or incontinence (controls) and to determine whether incontinence or a catheter are independent risk factors for death, institutionalization, or functional decline.DesignProspective cohort study conducted between 2006 and 2008 with a 12-month follow-up.SettingEleven medical wards of 2 university teaching hospitals and 1 teaching hospital in the Netherlands.ParticipantsParticipants included 639 patients who were 65 years and older, acutely hospitalized for more than 48 hours.MeasurementsBaseline characteristics, functional status, presence of urinary incontinence or catheter, length of hospital stay, mortality, institutionalization, and functional decline during admission and 3 and 12 months after admission were collected. Regression analyses were done to study a possible relationship between incontinence, catheter use, and adverse outcomes at 3 and 12 months.ResultsOf all patients, 20.7% presented with incontinence, 23.3% presented with a catheter, and 56.0% were controls. Patients with a catheter scored worst on all baseline characteristics. A catheter was an independent risk factor for mortality at 3 months (odds ratio [OR] = 1.73, 95% confidence interval [CI] 1.10–2.70), for institutionalization at 12 months (OR = 4.03, 95% CI 1.67–9.75), and for functional decline at 3 (OR = 2.17, 95% CI 1.32–3.54) and 12 months (OR = 3.37, 95% CI 1.81–6.25). Incontinence was an independent risk factor for functional decline at 3 months (OR = 1.84, 95% CI 1.11–3.04).ConclusionThere is an association between presence of a catheter, urinary incontinence, and development of adverse outcomes in hospitalized older patients.     

Malnutrition in Relation to Muscle Mass,Muscle Quality,and Muscle Strength in Hospitalized Older Adults

ObjectivesMuscle quality is an essential muscle metric, which can be assessed by measuring intermuscular adipose tissue (IMAT) and skeletal muscle radiodensity (SMD) via computed tomography (CT) images. We aimed to explore the associations of Global Leadership Initiative on Malnutrition (GLIM)–defined malnutrition with muscle mass, muscle quality, and muscle strength in hospitalized older adults.DesignA cross-sectional study.Setting and participantsHospitalized older patients.MethodsMalnutrition was defined by the GLIM criteria after screening by the Mini Nutrition Assessment–Short Form (MNA-SF). Chest CT images were used to segment skeletal muscle area (SMA) and IMAT, and to measure SMD. Skeletal muscle index (SMI) was calculated by SMA (cm²)/body height squared (m²). Handgrip strength (HGS) was measured using a digital dynameter. Univariate and multivariate logistic regression models were performed to calculate odds ratios (ORs) and 95% CIs.ResultsWe included 1135 patients. The MNA-SF score is positively associated with SMI, SMD, and HGS, but negatively associated with IMAT. Compared to patients with normal nutrition, patients with malnutrition had significantly lower SMD and HGS in both men and women. Women with malnutrition had significantly higher IMAT than women with normal nutrition, whereas men with malnutrition had significantly lower SMI than men with normal nutrition. After adjustment for confounders, SMI (adjusted OR 0.95, 95% CI 0.93, 0.98), SMD (adjusted OR 0.94, 95% CI 0.93, 0.98), and HGS (adjusted OR 0.91, 95% CI 0.89, 0.94) were significantly and negatively associated with malnutrition. IMAT appeared to be positively associated with malnutrition, but the result was not statistically significant (adjusted OR 1.03, 95% CI 1.00, 1.07).Conclusions and ImplicationsOur study provides new evidence regarding the association between handgrip strength and malnutrition in older inpatients. Moreover, a small association of chest CT-–derived muscle quality and mass with malnutrition is identified.     

Delirium Superimposed on Dementia Strongly Predicts Worse Outcomes in Older Rehabilitation Inpatients

ObjectiveDelirium superimposed on dementia (DSD) is common in many settings. Nonetheless, little is known about the association between DSD and clinical outcomes. The study aim was to evaluate the association between DSD and related adverse outcomes at discharge from rehabilitation and at 1-year follow-up in older inpatients undergoing rehabilitation.DesignProspective cohort study.SettingHospital rehabilitation unit.ParticipantsA total of 2642 patients aged 65 years or older admitted between January 2002 and December 2006.MeasurementsDementia predating rehabilitation admission was detected by DSM-III-R criteria. Delirium was diagnosed with the DSM-IV-TR. The primary outcome was that of walking dependence (Barthel Index mobility subitem score of <15) captured as a trajectory from discharge to 1-year follow-up. A mixed-effects multivariate logistic regression model was used to analyze the association between DSD and outcome, after adjusting for relevant covariates. Secondary outcomes were institutionalization and mortality at 1-year follow-up, and logistic regression models were used to analyze these associations.ResultsThe median age was 77 years (interquartile range: 71–83). The prevalence of DSD was 8%, and the prevalence of delirium and dementia alone were 4% and 22%, respectively. DSD at admission was found to be significantly associated with almost a 15-fold increase in the odds of walking dependence (odds ratio [OR] 15.5; 95% Confidence Interval [CI] 5.6–42.7; P < .01). DSD was also significantly associated with a fivefold increase in the risk of institutionalization (OR 5.0; 95% CI 2.8–8.9; P < .01) and an almost twofold increase in the risk of mortality (OR 1.8; 95% CI 1.1–2.8; P = .01).ConclusionsDSD is a strong predictor of functional dependence, institutionalization, and mortality in older patients admitted to a rehabilitation setting, suggesting that strategies to detect DSD routinely in practice should be developed and DSD should be included in prognostic models of health care.     

Multiparticipant Rehabilitation in Skilled Nursing Facilities: An Observational Comparison Study

ObjectivesPost-acute care reform creates an impetus for skilled nursing facilities (SNFs) to reevaluate care delivery to promote value. One method to contain costs is to deliver rehabilitation with multiple individuals and 1 therapist. Our preliminary investigation proposed to identify clinical prescribing patterns for multiparticipant therapy and evaluate the impact on functional change.DesignThe study design was observational with prospective data collection.Setting and ParticipantsData were collected on 458 individuals admitted to 1 SNF.MeasuresTherapists administered the Short Physical Performance Battery (SPPB) and gait speed at admission and discharge. Unadjusted binomial logistic regression models analyzed the odds ratio for receiving multiparticipant therapy. Linear regression models analyzed the impact of multiparticipant therapy on functional outcomes.ResultsThe odds of receiving multiparticipant therapy were greater with private pay or managed care compared with Medicare A [odds ratio (OR) 2.542; 95% confidence interval (CI) 1.631–3.960 and OR 2.182; 95% CI 1.812–2.629] or a Medicare priority diagnosis (OR 1.333; 95% CI 1.176–1.511). The odds of not receiving multiparticipant therapy were greater with pain that affects activity and sleep (OR 0.836; 95% CI 0.710–0.984; OR 0.809; 95% CI 0.662–0.989). The amount of multiparticipant therapy sessions did not affect adjusted functional change in the SPPB or gait speed (P > .195). Irrespective of care delivery mode, individuals demonstrated levels of function predictive of adverse events at discharge.Conclusions and ImplicationsPayer source, diagnosis, and presence of significant pain may play a role in selection for multiparticipant therapy, with no differences in functional outcomes related to rehabilitation delivery. Importantly, individuals discharge from the SNF at alarmingly low levels of function, prompting the need to assess SNF rehabilitation and transition to the community, regardless of care delivery mode. Further research will inform an evidence-based decision guide regarding different modes and quality of SNF rehabilitation care delivery.     

Muscle Strength Definitions Matter: Prevalence of Sarcopenia and Predictive Validity for Adverse Outcomes Using the European Working Group on Sarcopenia in Older People 2 (EWGSOP2) Criteria

EWGSOP2 criteria for sarcopenia recommends the use of either handgrip strength (GS) or 5-times repeated chair stand test (RCS) as a muscle strength measure. We aim to compare the impact of different muscle strength definitions on sarcopenia prevalence and predictive validity for 2-year outcomes, using the EWGSOP2 clinical algorithm. We studied 200 community-dwelling older adults, comparing sarcopenia prevalence using three muscle strength definitions: 1) maximum GS (Asian Working Group cutoffs); 2) RCS-1 (standard cutoff >15s); and 3) RCS-2 (ROC-derived cutoff >12.5s). Two-year outcomes include: 1) Incident frailty (modified Fried criteria); 2) Physical performance [Short Physical Performance Battery (SPPB) score <10]; and 3) Quality of life [EuroQol-5 dimension (EQ-5D) <25th percentile]. We performed logistic regression on 2-year outcomes adjusted for age, gender, cognition and mood. Prevalence of confirmed sarcopenia was 14.5%, 4% and 9% for GS, RCS-1 and RCS-2 respectively. For 2-year outcomes (N=183), RCS-2 predicted incident frailty (OR: 5.7, 95% CI 1.4–22.8, p=0.013), low SPPB (OR: 4.4, 95% CI 1.4–13.1, p=0.009), and trended towards predicting low QOL (OR: 2.1, 95% CI 0.9–4.9, p=0.095). In contrast, GS and RCS-1 did not predict frailty nor low QOL, but predicted low SPPB only (GS: OR 3.8, 95% CI 1.3–10.6, p=0.01; RCS-1: OR: 8.8, 95% CI 2.2–35.0, p=0.002). Sarcopenia prevalence varies with muscle strength definitions, with GS being significantly higher vis-á-vis RCS definitions. Our results also support the use of population-specific over standard cutoffs for RCS to obtain intermediate estimates of sarcopenia prevalence and the best predictive validity for two-year outcomes.     

Implementation of discharge management for geriatric patients at risk of readmission or institutionalization.

OBJECTIVE: To evaluate whether implementation of discharge management by trained social workers or nurses reduces hospital readmissions and institutionalizations of geriatric patients in a real-world setting. DESIGN: Quasi-experimental design. SETTING: Six general hospitals in Belgium. PARTICIPANTS: A representative sample of 824 patients, 355 of whom were assigned to the experimental group receiving comprehensive discharge management and 469 to the control group receiving usual care. Inclusion criteria were patients admitted to a geriatric, rehabilitation, or internal medicine ward, not residing in a nursing home, and showing risk of readmission or institutionalization on admission in the hospital. INTERVENTION: In-hospital discharge planning according to a case management protocol allowing for adjustment to participating hospitals' case mix and patients' and families' specific needs. MAIN OUTCOME MEASURES: Hospital readmission within 15 and 90 days post discharge; institutionalization at discharge and within 15 and 90 days post discharge. RESULTS: Discharge management resulted in fewer institutionalizations (n = 53; 14.9%) compared with usual care (n = 130; 23.7%) (adjusted odds ratio = 0.47; CI 95% = 0.31-0.70). Readmission rates between the intervention and usual care group were not significantly different. CONCLUSIONS: This implementation project showed that a discharge planning intervention can reduce institutionalization rates of elderly patients in real-life settings.     

Predicting cause-specific mortality of older men living in the veterans home by handgrip strength and walking speed: a 3-year, prospective cohort study in Taiwan

ObjectiveTo determine prognostic value of handgrip strength (HGS) and walking speed (WS) in predicting the cause-specific mortality for older men.DesignProspective cohort study.SettingBanciao Veterans Care Home.Participants558 residents aged 75 years and older.MeasurementsAnthropometric data, lifestyle factors, comorbid conditions, biomarkers, HGS, and WS at recruitment; all-cause and cause-specific mortality at 3 years after recruitment.ResultsDuring the study period, 99 participants died and the baseline HGS and WS were significantly lower than survivors (P both <.001). Cox survival analysis showed that subjects with slowest quartile of WS were at significantly higher risk of all-cause mortality and cardiovascular mortality (hazard ratio [HR] 3.55, 95% confidence interval [CI] 1.69–7.43; HR 11.55, 95% CI 2.30–58.04, respectively), whereas the lowest quartile of HGS significantly predicted a higher risk of infection-related death (HR 5.53, 95% CI 1.09–28.09). Participants in the high-risk status with slowest quartile for WS but not those in the high-risk status with weakest quartile for HGS had similar high risk of all-cause mortality with the group with combined high-risk status (HR 2.96, 95% CI 1.68–5.23; HR 2.58, 95% CI 1.45–4.60, respectively) compared with the participants without high-risk status (reference group).ConclusionsSlow WS predicted all-cause and cardiovascular mortality, whereas weak HGS predicted a higher risk of infection-related death among elderly, institutionalized men in Taiwan. Combining HGS with WS simultaneously had no better prognostic value than using WS only in predicting all-cause mortality.     

Effects of Nutritional Interventions on Nutritional and Functional Outcomes in Geriatric Rehabilitation Patients: A Systematic Review and Meta-Analysis

ObjectivesIt has been recognized that nutritional interventions play a role in improving the nutritional and functional status of older persons. This systematic review summarizes the evidence on nutritional and functional outcomes of nutritional interventions alone or in combination with physical exercise in geriatric rehabilitation patients.DesignEight electronic databases were searched until July 1, 2019 to identify nutritional intervention studies in patients aged ≥60 years who were admitted to geriatric rehabilitation. A meta-analysis was performed to quantify intervention effects on serum albumin, muscle mass, and hand grip strength (HGS).ResultsA total of 1962 studies were screened and 13 included in the systematic review. Studies were heterogeneous in interventions (4 nutritional interventions, 6 physical exercise + nutritional intervention, 1 timing of protein provision, 1 exercise + dietary advice, 1 nutrition-related nursing care) and outcomes. Among the 9 interventions that tested oral nutritional supplements (ONS) with protein, with or without exercise, 7 studies reported protein intake and 6 showed increased protein intakes, 2 of 5 studies showed increased albumin levels, and 5 of 9 reported an improvement in functional outcomes (BI, Functional Independence Measure, mobility). Meta-analyses showed no significant intervention effects on albumin [standardized mean difference (SMD) 0.45, 95% confidence interval (CI) −0.14, 1.04 (4 studies)], muscle mass [mean difference (MD) 2.14 kg, 95% CI –2.17, 6.45 (3 studies)], and HGS [SMD –0.04, 95% CI –0.55, 0.63 (3 studies)], but was based on a very limited number of studies.Conclusions and ImplicationsOnly a limited number of studies with heterogeneous nutritional interventions and outcomes were available in the geriatric rehabilitation population. Studies that included ONS improved nutritional outcomes, especially protein intake and albumin levels. Functional outcomes improved in the majority of reporting studies. This indicates benefits of protein supplementation, with or without exercise, in this population. Future well-designed and well-powered clinical trials are needed to clarify existing controversial aspects.     

After a stroke,ability with daily tasks of living improves after therapy based rehabilitation services

QuestionDo post-discharge rehabilitation services change recovery after stroke?Study designSystematic review with meta-analysis.Main resultsFourteen trials met inclusion criteria; 12 trials comparing therapy-based rehabilitation services were included in the meta-analysis (occupational therapy = 6 trials, physiotherapy = 2 trials and mixed services = 4 trials). At a median follow-up of 6 months, therapy-based rehabilitation services reduced the risk of deterioration in ability to undertake daily living tasks compared with control, (OR 0.72, 95% CI 0.57 to 0.92). Ability to carry out extended activities of daily living significantly improved in people undergoing therapy-based rehabilitation services compared with control (mean difference 0.17 95% CI 0.04 to 0.30). When similar categories of therapy were compared, only occupational therapy significantly reduced deterioration rate (occupational therapy: OR 0.73, 95% CI 0.55 to 0.96; physiotherapy OR 0.67, 95% CI 0.24 to 1.89; mixed services OR 0.72, 95% CI 0.41 to 1.27). Data were inconclusive with respect to mood, quality of life, need for long-term care and hospital readmission.Authors’ conclusionsPeople discharged to their homes after stroke are less likely to deteriorate if therapy-based rehabilitation services are provided compared with usual care or no routine intervention.     

Sarcopenia,Low Handgrip Strength,and Low Absolute Muscle Mass Predict Long-Term Mortality in Older Hospitalized Patients: An Observational Inception Cohort Study

ObjectiveSarcopenia is highly prevalent in hospitalized older patients and associated with short-term mortality. This study aimed to investigate whether sarcopenia and its measures handgrip strength (HGS) and muscle mass at hospital admission were associated with long-term mortality in a cohort of hospitalized older patients.DesignObservational, prospective, longitudinal inception cohort study.Setting and ParticipantsAcademic teaching hospital; patients age ≥70 years admitted to the internal medicine, acute admission, trauma, or orthopedic wards.MethodsHGS and muscle mass were measured at admission using a hand dynamometer and bioelectrical impedance analysis. Sarcopenia was determined based on the European Working Group on Sarcopenia in Older People definition. HGS and muscle mass (skeletal muscle mass index, appendicular lean mass, relative skeletal muscle mass) were expressed as sex-specific tertiles. The associations of sarcopenia, HGS, and muscle mass with mortality (during a follow-up of 3.4-4.1 years) were analyzed using Cox regression, adjusted for age, sex, comorbidity, and weight or height. Associations of HGS and muscle mass were stratified by sex.ResultsOut of 363 patients [mean age: 79.6 years (standard deviation: 6.4), 49.9% female] 49% died. Probable sarcopenia (prevalence of 53.7%) and sarcopenia (prevalence of 20.8%) were significantly associated with long-term mortality [hazard ratio (HR) 1.53, 95% confidence interval (CI) 1.08?2.17 and 1.71 95% CI 1.12?2.61, respectively]. Low HGS, skeletal muscle mass index, and appendicular lean mass were associated with a higher mortality risk (lowest tertile vs highest tertile: HR 2.660, 95% CI 1.40?5.05; HR 1.95, 95% CI 1.06?3.58 and HR 1.99 (95% CI 1.12?3.53) in male patients. No statistically significant associations of relative muscle mass with mortality were found.Conclusions and ImplicationsSarcopenia and its measures (low HGS and low absolute muscle mass at admission) predict long-term mortality in older hospitalized patients.     

Routinely Assessed Biochemical Markers Tested on Admission as Predictors of Adverse Outcomes in Hospitalized Elderly Patients

Abstract

Aim: To explore whether routinely assessed biochemical markers tested on admission will predict 3 predefined adverse outcomes for hospitalized elderly patients: discharge to a long-term care facility, in-hospital mortality, and prolonged hospital length of stay (> 14 days). Methods: A prospective observational study of elderly patients (aged ≥ 75 years) admitted to an acute-care geriatric ward over a 6-month period. Patients were assessed on admission and baseline characteristics were collected. Activities of daily living were assessed by the Barthel Index and cognitive function by the abbreviated mental test. Results from biochemical markers tested on admission were downloaded from the pathology laboratory database using patient details. Patients were folio wed-up with until discharge or in-hospital mortality. Results: A total of 392 patients formed the study population. Mean (standard deviation) age was 83.2 (± 5.5) years and 283 (72%) patients were men. Thirty-eight (10%) patients were discharged to a long-term care facility, 134 (34%) had a prolonged hospital length of stay, and 33 (8%) died in the hospital. Results from testing 5 biochemical markers independently predicted in-hospital mortality: hypoalbuminemia (adjusted odds ratio [OR], 2.5; 95% CI, 0.9–6.7; P = 0.04), low total cholesterol level (adjusted OR, 2.9; 95% CI, 1.3–6.3; P = 0.01), hyperglycemia (adjusted OR, 2.9; 95% CI, 1.2–7.4; P = 0.02), high C-reactive protein level (adjusted OR, 4.2; 95% CI, 1.3–13.4; P = 0.01), and renal impairment (adjusted OR, 3.8; 95% CI, 1.7–8.7; P = 0.002). High C-reactive protein level independently predicted prolonged hospital length of stay (OR, 1.7; 95% CI, 1.1–2.9; P = 0.03). Hypoalbuminemia predicted discharge to a long-term care facility independent of confounding factors except for physical dysfunction (OR, 2.4; 95% CI, 1.1–5.1; P = 0.03). Significance was reduced after adjustment for Barthel Index score (OR, 1.9; 95% CI, 0.9–4.1; P = 0.08). Conclusion: Testing of routinely assessed biochemical markers on admission predicted adverse hospital outcomes for elderly patients. Their inclusion in a standardized prediction tool may help to create interventions to improve such outcomes.     

Potential Risk Factors for,and Clinical Implications of,Delirium during Inpatient Rehabilitation: A Matched Case-Control Study

ObjectivesTo investigate the association between a wide set of baseline characteristics (age, sex, rehabilitation discipline), functional scores [Functional Independence Measure (FIM), cumulative Illness Rating Scale (CIRS)], diseases, and administered drugs and incident delirium in rehabilitation inpatients and, furthermore, to assess clinical implications of developing delirium during rehabilitation.DesignMatched case-control study based on electronic health record data.Setting and participantsWe studied rehabilitation stays of inpatients admitted between January 1, 2015, and December 31, 2018, to ZURZACH Care, Rehaklinik Bad Zurzach, an inpatient rehabilitation clinic in Switzerland.MethodsWe conducted unconditional logistic regression analyses to estimate adjusted odds ratios (AORs) with 95% CIs of exposures that were recorded in ≥5 cases and controls.ResultsAmong a total of 10,503 rehabilitation stays, we identified 125 validated cases. Older age, undergoing neurologic rehabilitation, a low FIM, and a high CIRS were associated with an increased risk of incident delirium. Being diagnosed with a bacterial infection (AOR 2.62, 95% CI 1.06-6.49), a disorder of fluid, electrolyte, or acid-base balance (AOR 2.76, 95% CI 1.19-6.38), Parkinson's disease (AOR 5.68, 95% CI 2.54-12.68), and administration of antipsychotic drugs (AOR 8.06, 95% CI 4.26-15.22), antiparkinson drugs (AOR 2.86, 95% CI 1.42-5.77), drugs for constipation (AOR 2.11, 95% CI 1.25-3.58), heparins (AOR 2.04, 95% CI 1.29-3.24), or antidepressant drugs (AOR 1.88, 95% CI 1.14-3.10) during rehabilitation, or an increased anticholinergic burden (ACB ≥ 3) (AOR 2.59, 95% CI 1.41-4.73) were also associated with an increased risk of incident delirium.Conclusions and ImplicationsWe identified a set of factors associated with an increased risk of incident delirium during inpatient rehabilitation. Our findings contribute to detect patients at risk of delirium during inpatient rehabilitation.     

Level of Medical Intervention in Geriatric Settings: Decision Factors and Correlation With Mortality

ObjectivesLevel of medical intervention (LMI) has to be adapted to each patient in geriatric care. LMI scales intend to help nonintensive care (NIC) decisions, giving priority to patient choice and collegial discussion. In the present study, we aimed to assess the parameters associated with the NIC decision and whether these parameters differ from those associated with in-hospital mortality.DesignProspective observational study.Setting and ParticipantsAll consecutive patients from a French 62-bed acute geriatric unit over 1 year.MethodsFactors from the geriatric assessment associated with the decision of NIC were compared with those associated with in-hospital and 1-year mortality, in univariate and multivariate analyses.ResultsIn total, 1654 consecutive patients (median age 87 years) were included. Collegial reflection led to NIC decision for 532 patients (32%). In-hospital and 1-year mortality were 22% and 54% in the NIC group vs 2% and 27% in the rest of the cohort (P < .001 for both). In multivariable analysis, high Charlson Comorbidity Index [odds ratio (OR) 1.15, 95% confidence interval (CI) 1.06-1.23, per point], severe neurocognitive disorders (OR 2.78, 95% CI 1.67-4.55), dependence (OR 1.92, 95% CI 1.45-2.59), and nursing home residence (OR 2.38, 95% CI 1.85-3.13) were highly associated with NIC decision but not with in-hospital mortality. Conversely, acute diseases had little impact on LMI despite their high short-term prognostic burden.Conclusions and ImplicationsNeurocognitive disorders and dependence were strongly associated with NIC decision, even though they were not significantly associated with in-hospital mortality. The decision-making process of LMI therefore seems to go beyond the notion of short-term survival.     

Passing the SNF Test: A Secondary Analysis of a Sepsis Transition Intervention Trial Among Patients Discharged to Post-Acute Care

ObjectivesSepsis survivors discharged to post-acute care facilities experience high rates of mortality and hospital readmission. This study compared the effects of a Sepsis Transition and Recovery (STAR) program vs usual care (UC) on 30-day mortality and hospital readmission among sepsis survivors discharged to post-acute care.DesignSecondary analysis of a multisite pragmatic randomized clinical trial.Setting and ParticipantsSepsis survivors discharged to post-acute care.MethodsWe conducted a secondary analysis of patients from the IMPACTS (Improving Morbidity During Post-Acute Care Transitions for Sepsis) randomized clinical trial who were discharged to post-acute care. IMPACTS evaluated the effectiveness of STAR, a nurse-navigator-led program to deliver best practice post-sepsis care. Subjects were randomized to receive either STAR or UC. The primary outcome was 30-day readmission and mortality. We also evaluated hospital-free days alive as a secondary outcome.ResultsOf 691 patients enrolled in IMPACTS, 175 (25%) were discharged to post-acute care [143 (82%) to skilled nursing facilities, 12 (7%) to long-term acute care hospitals, and 20 (11%) to inpatient rehabilitation]. Of these, 87 received UC and 88 received the STAR intervention. The composite 30-day all-cause mortality and readmission endpoint occurred in 26 (29.9%) patients in the UC group vs 18 (20.5%) in the STAR group [risk difference −9.4% (95% CI −22.2 to 3.4); adjusted odds ratio 0.58 (95% CI 0.28 to 1.17)]. Separately, 30-day all-cause mortality was 8.1% in the UC group compared with 5.7% in the STAR group [risk difference −2.4% (95% CI −9.9 to 5.1)] and 30-day all-cause readmission was 26.4% in the UC group compared with 17.1% in the STAR program [risk difference −9.4% (95% CI −21.5 to 2.8)].Conclusions and ImplicationsThere are few proven interventions to reduce readmission among patients discharged to post-acute care facilities. These results suggest the STAR program may reduce 30-day mortality and readmission rates among sepsis survivors discharged to post-acute care facilities.     

Eating Behaviors Are Associated With Physical Fitness and Body Composition Among US Army Soldiers

ObjectiveExamine associations between soldiers’ eating behaviors, compliance with body composition and fitness standards, and physical performance.DesignCross-sectional study.SettingEight Army installations.ParticipantsUS Army Soldiers (n = 1,591; 84% male).Main Outcome MeasuresCharacteristics, eating behaviors, compliance with body composition and physical fitness standards, and fitness level were assessed via questionnaire.AnalysisBivariate and multivariable logistic regression.ResultsEating mostly at a dining facility was associated with lower odds of body composition failure (odds ratio [OR], 0.44; 95% confidence interval [CI], 0.26–0.73); whereas, eating at a fast rate (OR, 1.51; 95% CI, 1.05–2.17) or often/always ignoring satiety cues (OR, 2.12; 95% CI, 1.06–4.27) was associated with higher odds of body composition failure. Eating mostly fast-food/convenience meals (OR, 1.75; 95% CI, 1.19–2.59) and eating at a fast rate (OR, 1.42; 95% CI, 1.04–1.93) was associated with higher odds of physical fitness failure. Skipping breakfast was associated with lower odds of high physical performance (OR, 0.41; 95% CI, 0.23–0.74); whereas, nutrition education was associated with higher odds of high physical performance (OR, 1.02; 95% CI, 1.01–1.04).Conclusions and ImplicationsAs eating behaviors are modifiable, findings suggest opportunities for improving the specificity of Army health promotion and education programs.
