Incidence of Hospitalization-Associated Disability in Older Patients With Heart Failure.

BACKGROUND: This study determined the incidence of hospitalization-associated disability (HAD) and its characteristics in older patients with heart failure in Japan. METHODS AND RESULTS: Ninety-six institutions participated in this nationwide multicenter registry study (J-Proof HF). From December 2020 to March 2022, consecutive heart failure patients aged ≥65 years who were prescribed physical rehabilitation during hospitalization were enrolled. Of the 9,403 patients enrolled (median age 83.0 years, 50.9% male), 3,488 (37.1%) had HAD. Compared with the non-HAD group, the HAD group was older and had higher rates of hypertension, chronic kidney disease, and cerebrovascular disease comorbidity. The HAD group also had a significantly lower Barthel Index score and a significantly higher Kihon checklist score before admission. Of the 9,403 patients, 2,158 (23.0%) had a preadmission Barthel Index score of <85 points. Binomial logistic analysis revealed that age and preadmission Kihon checklist score were associated with HAD in patients with a preadmission Barthel Index score of ≥85, compared with New York Heart Association functional classification and preadmission cognitive decline in those with a Barthel Index score <85. CONCLUSIONS: This nationwide registry survey found that 37.1% of older patients with HF had HAD and that these patients are indicated for convalescent rehabilitation. Further widespread implementation of rehabilitation for older patients with heart failure is expected in Japan.

Exploring the Frailty Components Related to Hospitalization-Associated Disability in Older Patients After Cardiac Surgery Using a Comprehensive Frailty Assessment.

BACKGROUND: We investigated the components of frailty associated with hospitalization-associated disability (HAD) after cardiac surgery.Methods and Results: This retrospective, observational study evaluated 1,446 older patients after elective cardiac surgery at the Sakakibara Heart Institute. We examined the association between HAD and 7 domains of frailty assessed by the Kihon Checklist. HAD was defined as a decline in the ability to perform activities of daily living (ADL) between admission and discharge, as assessed by the Barthel Index. Logistic regression and decision tree analysis were used to identify associations between the number and type of frailty components and HAD. Of the 1,446 patients, 190 were excluded, and 90 (7%) developed HAD. An increase in the number of frailty components was a risk factor for HAD (odds ratio: 1.88, 95% confidence interval: 1.62-2.17). Decision tree analysis identified physical functional decline, depression, and cognitive dysfunction as factors associated with HAD. The incidence of HAD was highest in cases of physical functional decline (21%) and lowest for cases in which the 3 aforementioned factors were absent (2.8%). CONCLUSIONS: An increased number of frailty factors increased the risk of HAD and the findings also reaffirmed the importance of a comprehensive assessment to evaluate the risk of HAD, including evaluation of physical function, cognitive function, and depression.

Research progress in the hospitalization-associated disability among elderly patients. / è€å¹´æ‚£è€ ä½é™¢ç›¸å ³æ€§å¤±èƒ½çš„ç ”ç©¶è¿›å±•.

Hospitalized patients who lose one or more activities of daily living at the time of discharge compared with 2 weeks before admission (before acute onset) are referred to as hospitalization-associated disability (HAD). The incidence of HAD is high among elderly patients, which leads to the increased readmission rates, long-term care rates, and mortality, bringing a huge burden on patients, families, and society. It is vital for doctors and nurses to identify the risk factors of HAD of the elderly patients and take targeted intervention measures to prevent and improve HAD. At present, the research on HAD in foreign countries is relatively perfect, while the research on HAD in China is still in its infancy, and there is still lack of systematic research and reports on the incidence, influencing factors, and intervention measures of HAD. Domestic clinical nursing practice can learn from foreign mature interventions, carry out cultural adjustment, create a friendly environment in the hospital for elderly patients, pay attention to the assessment of the influencing factors of HAD in elderly patients, and provide personalized and patient-centered nursing measures for hospitalized elderly patients according to the assessment results, maintain their function during hospitalization and prevent the occurrence of HAD.

Physical function examination at intensive care unit as predictive indicators for hospitalization-associated disability in patients after cardiovascular surgery.

BACKGROUND: Following cardiovascular surgery, patients are at high risk of requiring systemic management in the intensive care unit (ICU), resulting in hospitalization-associated disability (HAD). Predicting the risk of HAD during the postoperative course is important to prevent susceptibility to cardiovascular events. Assessment of physical function during the ICU stay may be useful as a prediction index but has not been established. METHODS: This prospective observational study conducted at a high-volume cardiovascular center included 236 patients (34% female; median age, 73 years) who required an ICU stay of at least 72 hours after surgery and underwent postoperative rehabilitation. HAD was defined as a decrease in the discharge Barthel index (BI) score of at least 5 points relative to the preadmission BI score. Physical Function ICU Test-scored (PFIT-s), Functional Status Score for the ICU (FSS-ICU), and Medical Research Council (MRC)-sumscore were used to assess physical function at ICU discharge. RESULTS: HAD occurred in 58 (24.6%) of the 236 patients following cardiovascular surgery. The cut-off points for HAD were 7.5 points for the PFIT-s (sensitivity 0.80, specificity 0.59), 24.5 points for the FSS-ICU (sensitivity 0.57, specificity 0.66), and 59.5 points for the MRC-sumscore (sensitivity 0.93, specificity 0.66). Multivariate logistic regression analysis revealed a PFIT-s of >7.5 points (odds ratio [OR], 4.84; 95% CI, 2.39-9.80; p < 0.001) and an MRC-sumscore of >59.5 points (OR, 2.43; 95% CI, 1.22-4.87; p = 0.012) as independent associated factors. CONCLUSIONS: We demonstrate that the PFIT-s and MRC-sumscore at ICU discharge may be helpful as a predictive indicator for HAD in patients having undergone major cardiovascular surgery.

Frailty and hospitalization-associated disability after pneumonia: A prospective cohort study.

BACKGROUND: Pneumonia is a major cause of morbidity and mortality in older adults. The role of frailty assessment in older adults with pneumonia is not well defined. Our purpose of the study was to investigate 30-day clinical course and functional outcomes of pneumonia in older adults with different levels of frailty. METHODS: A prospective cohort was conducted at a university hospital in Seoul, Korea with 176 patients who were 65 years or older and hospitalized with pneumonia. A 50-item deficit-accumulation frailty index (FI) (range: 0-1; robust < 0.15, pre-frail 0.15-0.24, mild-to-moderately frail 0.25-0.44, and severely frail ≥ 0.45) and the pneumonia severity CURB-65 score (range: 0-5) were measured. Primary outcome was death or functional decline, defined as worsening dependencies in 21 daily activities and physical tasks in 30 days. Secondary outcomes were intensive care unit admission, psychoactive drug use, nasogastric tube feeding, prolonged hospitalization (length of stay > 15 days), and discharge to a long-term care institution. RESULTS: The population had a median age 79 (interquartile range, 75-84) years, 68 (38.6 %) female, and 45 (25.5 %) robust, 36 (47.4 %) pre-frail, 37 (21.0 %) mild-to-moderately frail, and 58 (33.0 %) severely frail patients. After adjusting for age, sex, and CURB-65, the risk of primary outcome for increasing frailty categories was 46.7 %, 61.1 %, 83.8 %, and 86.2 %, respectively (p = 0.014). The risk was higher in patients with frailty (FI ≥ 0.25) than without (FI < 0.25) among those with CURB-65 0-2 points (75 % vs. 52 %; p = 0.022) and among those with CURB-65 3-5 points (93 % vs. 65 %; p = 0.007). In addition, patients with greater frailty were more likely to require nasogastric tube feeding (robust vs. severe frailty: 13.9 % vs. 60.3 %) and prolonged hospitalization (18.2 % vs. 50.9 %) and discharge to a long-term care institution (4.4 % vs. 59.3 %) (p < 0.05 for all). Rates of intensive care unit admission and psychoactive drug use were similar. CONCLUSIONS: Older adults with frailty experience high rates of death or functional decline in 30 days of pneumonia hospitalization, regardless of the pneumonia severity. These results underscore the importance of frailty assessment in the acute care setting.

Hospitalization-Associated Disability in Adults Admitted to a Safety-Net Hospital.

BACKGROUND: Little is known about hospitalization-associated disability (HAD) in older adults who receive care in safety-net hospitals. OBJECTIVES: To describe HAD and to examine its association with age in adults aged 55 and older hospitalized in a safety-net hospital. DESIGN: Secondary post hoc analysis of a prospective cohort from a discharge intervention trial, the Support from Hospital to Home for Elders. SETTING: Medicine, cardiology, and neurology inpatient services of San Francisco General Hospital, a safety-net hospital. PARTICIPANTS: A total of 583 participants 55 and older who spoke English, Spanish, or Chinese. We determined the incidence of HAD 30 days post-hospitalization and ORs for HAD by age group. MEASUREMENTS: The outcome measure was death or HAD at 30 days after hospital discharge. HAD is defined as a new or additional disability in one or more activities of daily living (ADL) that is present at hospital discharge compared to baseline. Participants' functional status at baseline (2 weeks prior to admission) and 30 days post-discharge was ascertained by self-report of ADL function. RESULTS: Many participants (75.3 %) were functionally independent at baseline. By age group, HAD occurred as follows: 27.4 % in ages 55-59, 22.2 % in ages 60-64, 17.4 % in ages 65-69, 30.3 % in ages 70-79, and 61.7 % in ages 80 or older. Compared to the youngest group, only the adjusted OR for HAD in adults over 80 was significant, at 2.45 (95 % CI 1.17, 5.15). CONCLUSIONS: In adults at a safety-net hospital, HAD occurred in similar proportions among adults aged 55-59 and those aged 70-79, and was highest in the oldest adults, aged ≥ 80. In safety-net hospitals, interventions to reduce HAD among patients 70 years and older should consider expanding age criteria to adults as young as 55.

Home Based Exercise Rehabilitation Programs to Prevent Physical Frailty and Hospitalization-Associated Disability.

Daily health management and exercise are important for staying healthy and avoiding the need for long-term care. However, it is not easy to maintain regular exercise. Therefore, exercise needs to be done efficiently. In recent years, due to the aging population and increasing severity of illness, older patients often experience a significant decline in physical function, even with minimal rest, which often interferes with their daily life after discharge from the hospital. Frailty not only affects ADLs, but also strongly influences prognosis, including the development of atherosclerotic disease and rehospitalization. This perspective is a summary of the 51st Metropolitan Public Lecture held on June 17, 2023, and discusses exercise-based rehabilitation programs that can be delivered at home to prevent physical frailty and avoid hospitalization-related disability.

Effect of comorbid heart failure assessed by plasma B-type natriuretic peptide level on the activities of daily living in patients with hospitalization-associated disability after aspiration pneumonia.

PURPOSE: We investigated the effects of comorbid heart failure on rehabilitation outcomes in patients with hospitalization-associated disability after aspiration pneumonia (AP). METHODS: This study included 134 patients with hospitalization-associated disability after AP. Patients were classified into heart failure (B-type natriuretic peptide (BNP) ≧100 pg/ml, n = 39) and non-heart failure (BNP < 100 pg/ml, n = 95) groups, and the rehabilitation outcomes of both groups were compared. RESULTS: Rehabilitation effectiveness was lower in heart failure group than in non-heart failure group (21.1 ± 22.6% vs 36.2 ± 30.8, p < 0.01). The rate of independent walking at discharge in heart failure group (28.2%) was significantly lower than in non-heart failure group (53.7%). Multiple linear regression analysis revealed that age, male, handgrip strength, quadriceps strength, functional oral intake scale, Mini Nutritional Assessment Short Form, and BNP were significantly associated with rehabilitation effectiveness. DISCUSSION: Results suggest that comorbid heart failure has a negative impact on rehabilitation outcomes in patients with hospital-associated disability after AP.

The Effectiveness of Frailty Intervention for Older Patients with Frailty during Hospitalization.

OBJECTIVES: This study aims to assess the effectiveness of a multidomain intervention program on the change in functional status of hospitalized older adults. DESIGN: This single-arm, prospective, non-randomized interventional study investigates the efficacy of a multidomain interventional program including cognitive stimulation activity, simple exercises, frailty education, and nutrition counseling. SETTING AND PARTICIPANTS: At a tertiary hospital in southern Taiwan, 352 eligible patients were sequentially enrolled. Included patients were aged ≥65 years (mean age, 79.6 ± 9.0 years; 62% male), scored 3-7 on the Clinical Frailty Scale (CFS), and were hospitalized in the geriatric acute ward. INTERVENTION: Those receiving standard care (physical rehabilitation and nutrition counseling) during January-July 2019 composed the historical control group. Those receiving the multidomain intervention during August-December 2019 composed the intervention group. MEASUREMENTS: The primary outcome was the change in activities of daily life (ADL) and frailty status, as assessed by Katz Index and Clinical Frailty Scale, with using the generalized estimating equation model. The length of hospital stay, medical costs, and re-admission rates were secondary outcomes. RESULTS: Participants undergoing intervention (n = 101; 27.9%) showed greater improvements in the ADL and CFS during hospitalization (ADL adjusted estimate, 0.61; 95% CI, 0.11-1.11; p = 0.02; CFS adjusted estimate, -1.11; 95% CI, -1.42- -0.80; p < 0.01), shorter length of hospital stay (adjusted estimate, -5.00; 95% CI, -7.99- -2.47; p < 0.01), lower medical costs (adjusted estimate, 0.58; 95% CI, 0.49-0.69; p < 0.01), and lower 30- and 90-day readmission rates (30-day adjusted OR [aOR], 0.12; 95% CI, 0.27-0.50; p < 0.01; 60-day aOR, 0.04; 95% CI, 0.01-0.33; p < 0.01) than did controls. CONCLUSIONS: Participation in the multidomain intervention program during hospitalization improved the functional status and decreased the hospital stay length, medical costs, and readmission rates of frail older people.

Adherence to Mediterranean Diet and Response to an Exercise Program to Prevent Hospitalization-Associated Disability in Older Adults: A Secondary Analysis from a Randomized Controlled Trial.

OBJECTIVES: To investigate the relationship between Mediterranean diet (MedDiet) adherence and response to an exercise and health education program to prevent hospitalization-associated disability (HAD) in acutely hospitalized older adults. DESIGN: Randomized controlled trial. SETTING AND PARTICIPANTS: Secondary analysis of a subset of 109 participants from AGECAR-PLUS study with available data on MedDiet adherence (mean age 87, and range 75-98). INTERVENTION: Participants were randomized into the control group (n = 46, usual care) or the intervention group (n = 63, supervised exercise and health education) at admission. MEASUREMENTS: MedDiet adherence was measured with MEDAS and through urinary total polyphenols (UTP). Functional status was assessed with the Barthel Index. RESULTS: At discharge, patients in the intervention group who had low levels of MedDiet or UTP showed an increase in functional status [adjusted mean (95% CI) = 77.8 (70.8-84.8) points, p = 0.005, and adjusted mean (95% CI) = 78.0 (68.3-87.7) points, p = 0.020, respectively]. CONCLUSION: Older individuals over age 75 with low MedDiet adherence were likely to benefit more from a physical exercise and health education intervention.

Predictive Value of the Hemoglobin-Geriatric Nutritional Risk Index in Patients with Heart Failure.

Malnutrition prevails among patients with heart failure (HF), increasing the likelihood of functional decline. We assessed the predictive value of the Hemoglobin-Geriatric Nutritional Risk Index (H-GNRI)-combining hemoglobin and the Geriatric Nutritional Risk Index (GNRI)-on prognosis in older patients with HF. We used the JMDC multicenter database to examine the potential associations between malnutrition risk and other outcome measures. The patients were categorized as low- (H-GNRI score = 0), intermediate- (H-GNRI score = 1), or high-risk (H-GNRI score = 2) based on their H-GNRI scores. The primary outcome measure was the Barthel Index (BI) gain; the secondary outcomes included the BI at discharge, the BI efficiency, length of hospital stay, in-hospital mortality, discharge to home or a nursing home, and hospitalization-associated disability. We analyzed 3532 patients, with 244 being low-risk, 952 being intermediate-risk, and 2336 being high-risk patients. The high-risk group of patients had significantly lower BI values at discharge, lower BI gains, reduced BI efficiency values, and prolonged hospital stays compared to those in the low-risk group. The high-risk patients also had higher in-hospital mortality rates, lower rates of discharge to home or a nursing home, and greater incidences of a hospitalization-associated disability in comparison to the low-risk group. The H-GNRI may serve as a valuable tool for determining prognoses for patients with HF.

Hospitalization-Associated Disability After Cardiac Surgery in Elderly Patients　- Exploring the Risk Factors Using Machine Learning Algorithms.

Background: Hospitalization-associated disability (HAD) is associated with prolonged functional decline and increased mortality after discharge. Therefore, we examined the incidence and risk factors associated with HAD in elderly patients undergoing cardiac surgery in Japan. Methods and Results: We retrospectively examined 2,262 elderly patients who underwent elective cardiac surgery at Sakakibara Heart Institute. HAD was defined as a functional decline between time of admission and discharge measured by the Barthel Index. We analyzed clinical characteristics using machine learning algorithms to identify the risk factors associated with HAD. After excluding 203 patients, 2,059 patients remained, of whom 108 (5.2%) developed HAD after cardiac surgery. The risk factors identified were age, serum albumin concentration, estimated glomerular filtration rate, Revised Hasegawa's Dementia Scale, N-terminal pro B-type natriuretic peptide, vital capacity, preoperative Short Physical Performance Battery (SPPB) score, operation times, cardiopulmonary bypass times, ventilator times, length of postoperative intensive care unit stay, and postoperative ambulation start day. The highest incidence of HAD was found in patients with an SPPB score ≤9 and in those who started ambulation >6 days after surgery (76.9%). Conclusions: Several risk factors for HAD are components of frailty, suggesting that preoperative rehabilitation to reduce the risk of HAD is feasible. Furthermore, the association between HAD and a delayed start of ambulation reaffirms the importance of early mobilization and rehabilitation.

The Severity of Acute Illness and Functional Trajectories in Hospitalized Older Medical Patients.

BACKGROUND: Acute diseases and hospitalization are associated with functional deterioration in older persons. Although most of the functional decline occurs before hospitalization in response to the acute diseases, the role played by comorbidity in the functional trajectories around hospitalization is unclear. METHODS: Observational prospective study of 696 elderly individuals hospitalized in two Italian general medicine wards. Functional status of the elderly patients at 2 weeks before hospitalization (baseline), at hospital admission, and at discharge was measured by the Barthel Index. Comorbidity was measured at admission by the Geriatric Index of Comorbidity (GIC), a tool mostly based on illness severity. The association of GIC with changes in functional status before hospitalization (between baseline and admission), during hospitalization (between admission and discharge), and in the overall period between baseline and discharge was assessed by logistic regression analyses. Hospitalization-associated disability (HAD) was defined as a functional decline between baseline and discharge. RESULTS: Illness severity (GIC 3-4 vs 1-2: odds ratio [OR] 2.2, 95% CI [confidence interval] 1.5-3.3, p < .0001) and older age significantly predicted prehospital functional decline (between baseline and admission). Illness severity (OR 1.9, 95% CI 1.2-3, p = .004) and older age were also predictive of HAD, even after adjustment for each coded primary discharge diagnosis. After adjustment for the occurrence of prehospital functional decline, however, illness severity and older age were not predictive of HAD anymore. CONCLUSIONS: The severity of illnesses was strongly associated with adverse functional outcomes around hospitalization, but frailty, intended as functional vulnerability to the acute disease before hospitalization, was a stronger predictor of HAD than illness severity and age.
