Prognostic impact of hospital-acquired disability in elderly patients with heart failure

Association between phase angle and hospital-associated disability in hospitalized patients in the internal medicine ward: A prospective observational study

OBJECTIVE

This study aimed to evaluate the association between the phase angle (PhA) and hospital-associated disability (HAD) in older patients admitted to an internal medicine ward.

METHODS

This was a prospective observational study in a single acute care hospital. HAD was defined as a decrease of at least five points in the Barthel index at discharge compared to pre-admission. Multiple logistic regression analysis was used to determine the association between PhA and HAD. The cut-off point for PhA was evaluated using a receiver operating characteristic curve.

RESULTS

This study included 215 patients (113 males; mean age: 80.8 years). The HAD incidence rate was 27.9 %. Multiple logistic regression analysis showed that PhA was associated with HAD (odds ratio: 3.47, 95 % confidence interval: 1.95-6.18, p < 0.001). The PhA cut-off points for predicting HAD were 3.7° for men and 3.6° for women.

CONCLUSION

PhA was associated with HAD in older patients admitted to the internal medicine ward and may be a useful indicator for predicting HAD.

Hospitalization-Associated Disability and 1-Year Mortality Risk in Older Patients With Heart Failure

OBJECTIVES

Hospitalization-associated disability (HAD) is the loss of the ability to perform one of the basic activities of daily living (ADLs) required for independent living during hospitalization. This study aimed to determine whether HAD is a significant prognostic risk factor in older patients with heart failure (HF) and independent ADLs.

DESIGN

Prospective, nationwide, multicenter registry study conducted between December 2020 and March 2022.

SETTING AND PARTICIPANTS

This study was conducted across 96 centers in Japan and included 6519 older patients (aged ≥65 years) with HF who were independent in ADL before hospitalization.

METHODS

HAD was defined as a drop of at least 5 points in the Barthel Index (BI) at discharge, relative to a stable score before hospitalization. Subgroup analysis classified HAD as mild (a decrease of 5-15 points in the BI) and severe (a decrease of ≥20 points in the BI). The primary outcome was all-cause mortality within 1 year after hospital discharge, and the secondary outcomes were HF-related mortality and rehospitalization.

RESULTS

All-cause mortality, HF-related mortality, and rehospitalization rates within 1 year were 12%, 5%, and 41%, respectively. Multivariate Cox regression analysis revealed that HAD increased the risk of 1-year all-cause mortality after hospital discharge (adjusted hazard ratio, 1.749; 95% CI, 1.475-2.075). Subgroup analysis showed a significantly higher risk of all-cause mortality among patients with severe HAD than among those with mild HAD (1.388; 1.109-1.739). HAD was a significant risk factor for HF-related mortality (1.556; 1.216-2.017). However, no relationship was observed between HAD and readmission (1.062; 0.970-1.163).

CONCLUSIONS AND IMPLICATIONS

The development of HAD was identified as a significant risk factor for 1-year post-discharge mortality among older patients with HF who were independent in ADLs before hospitalization. Preventing minor declines in ADL and mitigating any ADL impairments during hospitalization are crucial to avoiding a worsening prognosis.

Length of stay and prior heart failure admission in frailty and heart failure: A systematic review and meta-analysis

AIMS

The aim of this study was to compare the differences in length of stay (LoS) and prior hospitalization due to heart failure (HHF) in patients with HF and frailty versus without frailty.

METHODS AND RESULTS

From inception until August 2024, PubMed, Scopus, Web of Science and Cochrane Library were searched. To examine the association related to LoS and HHF in patients with HF, a meta-analysis using a random-effects model was conducted (CRD42024570604). Our main analysis demonstrated a significantly increased LoS in patients with frailty versus those without frailty [n = 10; mean difference (MD): 3.67; 95% CI: 2.26-5.08, I2 = 93%, P < 0.01]. Likewise, patients with frailty had significantly increased odds of HHF [n = 17; odds ratio (OR): 1.76; 95% CI: 1.50-2.07, I2 = 81%, P < 0.01]. Risk of bias assessment of the included studies was overall fair, while Egger's test showed publication bias regarding studies that examined LoS (P = 0.02).

CONCLUSIONS

Patients with frailty have longer LoS and more frequent HHF, underscoring the need for early, targeted interventions to manage frailty that may be attributed primarily to ageing and comorbidity-related status.

Dysphagia development in heart failure patients: A scoping review

OBJECTIVE

Dysphagia significantly affects older adults, particularly those with heart failure (HF). This scoping review aimed to delineate the development of dysphagia and its contributing factors in patients with HF.

METHODS

We systematically searched MEDLINE, EMBASE, CINAHL, and CENTRAL databases up to September 2023, focusing on studies involving HF patients aged 60 and above, particularly those assessing post-hospitalization dysphagia.

RESULTS

Of 1,076 identified studies, nine were relevant. The prevalence of dysphagia at admission was 23.6 % (14.1 - 32.9), with 9.4 % (4.5 - 13.8) persisting until discharge. The evaluation of dysphagia primarily relies on oral intake assessments, highlighting several risk factors, including high inflammation, low energy intake, advanced age, low Barthel Index scores, poor oral health, antipsychotic usage, and low maximum tongue pressure. It is important to note potential author bias and overlap among study populations.

CONCLUSIONS

This review highlights the significant development of dysphagia in patients with HF, and the prevalence of newly developed dysphagia was 23.6 % (14.1 - 32.9). Key risk factors include older age, high inflammation, low activities of daily living, and sarcopenia, which is suggested as a pathogenic mechanism in dysphagia. Future research should focus on diverse samples, investigate the impact of sarcopenia and cachexia, and objectively assess swallowing function.

Age-Specific Changes in Physical Function in Patients with Acute Decompensated Heart Failure

Cardiac rehabilitation (CR) improves physical function in patients with acute decompensated heart failure (ADHF) and frailty. However, few studies have assessed physical function through multiple measures during hospitalization; moreover, the effect of age remains unclear. This study aimed to evaluate age-specific changes in physical function during the acute-phase treatment period in patients with ADHF. Patients with ADHF hospitalized between June 2018 and June 2023, who were aged ≥ 60 years and underwent CR, were included in the study. Physical function assessments at admission and discharge included grip strength, quadriceps isometric strength, short physical performance battery (SPPB), gait speed, and frailty. Changes in physical function from admission to discharge were assessed. The mean age of the 531 patients was 79.8 ± 9.0 years and 58% were male. Physical function at admission and discharge significantly decreased with age according to all measures. In patients aged ≥ 90 years, quadriceps isometric strength (0.27 ± 0.11 kgf/BW kg) and the SPPB score (4.5 ± 3.6 points) were severely impaired at admission. However, no significant differences were observed in changes in physical function according to age; the improvement in the SPPB score tended to increase with age (+1.7 ± 1.9, +2.3 ± 2.1, +2.2 ± 2.4, and +2.3 ± 1.8, in the 60-69-, 70-79-, 80-89-, and ≥ 90-year age groups, respectively). The improvement in frailty was similar in all groups. Although physical function declined with age, the changes in physical function were similar in patients with ADHF at any age above 60 years who underwent CR.

Effect of basic activities of daily living independence on home discharge and long-term outcomes in patients hospitalized with heart failure

Patients hospitalized for heart failure (HF) experience impairments in functional status, primarily affecting basic activities of daily living (ADL). We investigated the independent effect of functional status for ADL on patient-centered outcomes (i.e., home discharge) and conventional clinical outcomes in HF. We analyzed 2936 consecutive hospitalized patients with HF from a prospective multicenter registry. The functional status of ADL was assessed before discharge by using the Barthel index (BI). Patients were categorized into the lower BI group (≤85; the lowest tertile) and higher BI group (>85). We evaluated the risk-adjusted association between BI and non-home discharge, as well as the two-year all-cause mortality. Exploratory subgroups included patients categorized by age, sex, HF hospitalization, left ventricular ejection fraction, body mass index, and estimated glomerular filtration rate (eGFR). Of the participants (age: 79 [69-85] years; 41.1% women), 86.3% were discharged home. A lower BI was independently associated with non-home discharge (OR: 5.12, 95% CI 3.86-6.80) and higher all-cause mortality rates (HR: 1.96, 95% CI 1.58-2.45). Two-year cardiac and non-cardiac mortality rates were higher in the lower BI group; however, the proportion of cardiac causes in two-year deaths did not differ between the lower and higher BI groups (48.8% vs. 49.5%, P = 0.891). Subgroup analyses consistently demonstrated an association between two-year mortality and lower BI; however, this association was stronger among patients with a higher eGFR (P-value for interaction = 0.004). A lower BI was independently associated with non-home discharge and higher mortality rates because of cardiac- and non-cardiac-related causes in hospitalized patients with HF.

Relationship Between the Frequency and Duration of Physical Therapy and Hospitalization-associated Disability Among Geriatric Patients with Heart Failure

OBJECTIVE

The aim of this study was to examine the relationship between the frequency and duration of physical therapy (PT) and the development of hospitalization-associated disability (HAD) in hospitalized geriatric patients with heart failure (HF).

METHODS

This single-center, retrospective, observational study included hospitalized patients with HF aged 65 years or older who had received PT. Data regarding demographics, comorbidities, laboratory findings, medications, rehabilitation, and activities of daily living (ADLs) status were collected from electronic medical records. Based on the average frequency and duration of PT, patients were divided into three groups: Group 1, ≥3 days/week and ≥120 minutes/week; Group 2, ≥3 days/week and <120 minutes/week; and Group 3, <3 days/week and <120 minutes/week. Logistic regression analysis was performed to identify the association between the average frequency and duration of weekly PT and the incidence of HAD.

RESULTS

In all, 105 patients (mean age, 84.8 years; proportion of women, 59%) were enrolled in the study, and 43 (41.0%) patients exhibited HAD at discharge. In the multivariate logistic regression analysis, Group 2 (odds ratio [OR], 3.66) and Group 3 (OR, 6.71) had a significantly elevated risk of developing HAD using Group 1 as the reference, even after adjusting for age, ADLs before admission, cognitive function, and severity of HF.

CONCLUSION

This study showed that a lower frequency and shorter duration of PT are associated with developing HAD in hospitalized geriatric patients with HF. However, further prospective studies are required to confirm these findings.

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.

Kinesiophobia and associated variables in patients with heart failure

AIMS

Patients with heart failure (HF) can exhibit kinesiophobia, an excessive, debilitating, and irrational fear of movement. This study aimed to enhance the understanding of kinesiophobia in patients with HF by analysing associations with the following variables: musculoskeletal pain, quality of life, quality of sleep, functional capacity, disability, frailty, sex, and age.

METHODS AND RESULTS

In this cross-sectional study, 107 participants were included, with ages ranging from 28 to 97 years (57% men, mean age 73.18 ± 12.68 years). Multiple regression analyses were performed with all variables, including polynomial regressions for variables with a non-linear relationship. Kinesiophobia was significantly correlated (P < 0.01) with musculoskeletal pain, quality of life, quality of sleep, functional capacity, disability, and being at risk of frailty, while age and sex were not statistically significant. Frailty disability and musculoskeletal pain intensity were variables linearly associated with kinesiophobia, while quality of sleep and disability had a non-linear relationship with kinesiophobia.

CONCLUSION

Kinesiophobia needs to be evaluated and better understood in patients with HF to improve physical activity and exercise adherence. This study found that musculoskeletal pain intensity, quality of sleep, disability, and frailty risk have a significant association with kinesiophobia in patients with HF. Our results suggest multi-dimensional associations of kinesiophobia in patients with HF, which require further examination and understanding.

The association between oral health status and physical function in elderly patients with acute heart failure

OBJECTIVES

Oral health problems are common and are associated with various geriatric conditions in older adults. The importance of oral health has not been fully highlighted in the assessment and management of patients with heart failure. Here, we investigated the association between oral health status and the decline in physical function during hospitalization in elderly patients with acute heart failure.

MATERIALS AND METHODS

We evaluated oral health using the revised oral assessment guide in 77 patients aged 65 years or older who were admitted to hospital for acute heart failure. Oral health problems were defined as a revised oral assessment guide score ≥9.

RESULTS

Oral health problems were identified in 66.2% of the patients. Patients with oral health problems had high prevalence of decreased physical function, undernutrition, and cognitive impairment. A reduction in the Barthel Index, as an indicator of activities of daily living during hospitalization, was significant in the enrolled patients. The Barthel Index decreased more in patients with oral health problems than those with normal oral health. Furthermore, the revised oral assessment guide score on admission was found to be the only independent predictor of changes in the Barthel Index during hospitalization in the multivariate analyses.

CONCLUSIONS

Oral assessment using the revised oral assessment guide during hospitalization could provide useful information for the management of elderly heart failure patients.

Early mobilization for acute heart failure: A scoping and a systematic review

Early mobilization of hospitalized patients is beneficial under certain circumstances. This has been applied in clinical practice for patients with acute heart failure (HF). However, its current definition, effectiveness, and safety are not well established. This review aimed to clarify the current definition of "early mobilization," and summarize its effectiveness and safety in acute HF. We conducted a scoping review to define early mobilization (Part 1) and a systematic review and meta-analysis (Part 2) to evaluate its effectiveness and safety. For Part 1, we searched MEDLINE (Ovid), and for Part 2, we searched the Cochrane Central Register of Controlled Trials, MEDLINE (Ovid), Embase (ProQuest Dialog), CINAHL, and PEDro. We included 12 studies in Part 1 and defined early mobilization as protocol-based interventions or walking within 3 days of admission. Based on this definition, two observational studies were included in Part 2, with no randomized controlled trials. Early mobilization may result in a large reduction in the readmission rate compared with that of the control (two studies, 283 participants: odds ratio 0.25, 95 % confidence interval 0.14 to 0.42; I2 = 0 %; low certainty evidence). We could not define frequency, intensity, or quantity because many of the included studies did not describe them. In conclusions, our review suggests that early mobilization, defined as protocol-based interventions or walking within 3 days of admission, may be associated with a low readmission rate in patients with acute HF. Future studies are essential, to investigate the causal relationship between early mobilization and possible outcomes.

Geriatric Nutritional Risk Index Predicts High Activities of Daily Living at Discharge in Older Patients with Heart Failure after Cardiac Rehabilitation

BACKGROUND

Hospitalization often leads to a decline in activities of daily living (ADL) in older patients with heart failure. Although cardiac rehabilitation (CR) improves ADL, it can be difficult to perform CR due to the deconditioning of these patients. This study aimed to examine the factors associated with ADL at discharge in older patients with heart failure who underwent CR.

METHODS

A total of 86 of 110 older heart failure patients aged ≥ 75 years (average age, 86.9 ± 5.7 years) transferred to our institution for CR were enrolled and classified into high ADL at discharge (n = 54) and low ADL at discharge (n = 32) groups. Physical characteristics, comorbidities, medications, blood test data, echocardiographic data, and nutritional status (Geriatric Nutritional Risk Index [GNRI]) were retrospectively examined from medical records. ADL were assessed using the Barthel Index (BI) at admission and discharge. Considering multicollinearity, the relationship between high ADL (BI ≥ 60) at discharge and these assessments at admission was analyzed using multiple logistic regression analysis. The receiver operating characteristic curve was analyzed to calculate the cutoff values for the parameters identified by the multiple logistic regression analysis.

RESULTS

The GNRI was the only independent factor predicting high ADL at discharge (p = 0.041; odds ratio [OR], 1.125; 95% confidence interval [CI], 1.005-1.260). The area under the receiver operating characteristic curve for the GNRI was 0.770 (95% CI, 0.664-0.876). The cutoff value for the GNRI was 83.4 (sensitivity, 85.2%; specificity, 62.5%).

CONCLUSION

These findings suggest that the GNRI score at admission predicts high ADL at discharge in older patients with heart failure who underwent CR.

In-Hospital Fall Risk Prediction by Objective Measurement of Lower Extremity Function in a High-Risk Population

OBJECTIVES

Limited data exist regarding association between physical performance and in-hospital falls. This study was performed to investigate the association between physical performance and in-hospital falls in a high-risk population.

DESIGN

Retrospective cohort study.

SETTING AND PARTICIPANTS

The study population consisted of 1200 consecutive patients with a median age of 74 years (50.8% men) admitted to a ward with high incidence rates of falls, primarily in the departments of geriatrics and neurology, in a university hospital between January 2019 and December 2021.

METHODS

Short Physical Performance Battery (SPPB) was measured after treatment in the acute phase. As the primary end point of the study, the incidence of in-hospital falls was examined prospectively based on data from mandatory standardized incident report forms and electronic patient records.

RESULTS

SPPB assessment was performed at a median of 3 days after admission, and the study population had a median SPPB score of 3 points. Falls occurred in 101 patients (8.4%) over a median hospital stay of 15 days. SPPB score showed a significant inverse association with the incidence of in-hospital falls after adjusting for possible confounders (adjusted odds ratio for each 1-point decrease in SPPB: 1.19, 95% CI 1.10-1.28; P < .001), and an SPPB score ≤6 was significantly associated with increased risk of in-hospital falls. Inclusion of SPPB with previously identified risk factors significantly increased the area under the curve for in-hospital falls (0.683 vs. 0.740, P = .003).

CONCLUSION AND IMPLICATIONS

This study demonstrated an inverse association of SPPB score with risk of in-hospital falls in a high-risk population and showed that SPPB assessment is useful for accurate risk stratification in a hospital setting.

Association between Hospital-acquired Disability and Clinical Outcomes in Older Patients Who Underwent Cardiac Surgical

OBJECTIVE

This study aimed to clarify the association between hospital-acquired disability (HAD) and prognosis in older patients who underwent cardiac surgery.

METHODS

This single-center, retrospective, observational study included 141 patients aged ≥65 years who underwent cardiac surgery at our hospital from November 2016 to August 2021. The primary endpoint of this study was the occurrence of major adverse cardiac and cerebrovascular events (MACCEs) within 2 years of hospital discharge. HAD was defined as a score of ≤5 on any one of the functional independence measure (FIM) subitems at discharge compared to preoperatively.

RESULTS

MACCE was observed in 16.3%, and the incidence of MACCE was significantly higher in the HAD group than that in the non-HAD group (12.1 vs. 34.5%, log-rank, p = 0.003). HAD was also significantly associated with the MACCE (hazard ratio [HD]: 2.575, 95% confidence interval [CI]: 1.001-9.655, p = 0.046). The incidence rate of HAD was 20.6%, with age (odds ratio [OR]: 1.260, 95% CI: 1.080-1.470, p = 0.004), preoperative short physical performance battery (SPPB) score (OR: 0.462, 95% CI: 0.301-0.708, p <0.001), and postoperative delirium (OR: 6.660, 95% CI: 1.480-30.000, p = 0.014) identified as significant factors.

CONCLUSION

HAD is an independent predictor of MACCE in older patients who underwent cardiac surgery.

Radiological lung sequelae, functional status and symptoms in older patients 3 and 6 months after hospitalization for COVID-19 pneumonia

The aim of our study was to assess the lung sequelae and clinical consequences 3 and 6 months after hospitalization for COVID-19 pneumonia in older patients. An observational study was conducted on 55 patients aged 65 years and older. Activities of daily living (ADL) and clinical frailty scale (CFS) were assessed at baseline and after 3 months. Both quantitative assessment at chest high-resolution computed tomography (CT) and semi-quantitative severity score (CTSS) were performed at baseline and after 3 and 6 months. Mean age: 82.3 ± 7.1 years. Male prevalence: 56.4%. After 6 months, ground-glass opacities (GGO) were still detectable in 22% of subjects, while consolidations were no longer appreciable. During follow-up, CTSS reached an overall median score of zero after 6 months. Fibrotic-like changes were found in 40% of subjects with an overall median score of 0 (0-5) points, being more prevalent in males. Patients reporting worsening ADL and CFS were 10.9% and 45.5%, respectively. They were associated with the burden of comorbidities, especially history of heart failure and chronic obstructive pulmonary disease at baseline. Amnesic disorders, exertional dyspnea, and fatigue were the most relevant symptoms reported. No association emerged between persistent or new-onset symptoms and evidence of fibrotic-like changes. The typical chest CT abnormalities of the COVID-19 pneumonia acute phase resolved in most of our older patients. Mild fibrotic-like changes persisted in less than half of the patients, especially males, without significantly affecting the functional status and frailty condition, which instead were more likely associated with pre-existing comorbidities.

Relationship between instrumental activities of daily living decline during hospitalization and one-year mortality in elderly patients with heart failure: A multi-center prospective cohort study

BACKGROUND

It remains unclear whether instrumental activities of daily living (IADL) decline during hospitalization is related to mortality rates. This study examined the relationship between IADL decline during hospitalization and the one-year mortality rate in elderly heart failure (HF) patients.

METHODS

Five hundred seventy-six consecutive patients who were hospitalized for acute decompensated HF and underwent rehabilitation were divided into groups based on changes in IADL during hospitalization: IADL maintained and IADL decline. IADL was assessed by the National Center for Geriatrics and Gerontology-Activities of Daily Living Scale (NCGG-ADL). IADL decline was defined as Δ NCGG-ADL ≤ -1 point. The primary outcome was one-year all-cause mortality rate after discharge. Outcomes were examined using the Kaplan-Meier method with the log-rank test and Cox proportional hazards models using the existing prognostic risk factors for HF.

RESULTS

Of 576 patients, 20% (n = 113) had IADL decline during hospitalization, and 9.2% (n = 35) and 6.0% (n = 18) died of all-cause and cardiovascular disease within one year after discharge, respectively. The IADL-decline group had significantly higher one-year all-cause mortality rates after adjusting for risk factors (hazard ratio: 1.923, 95% confidence interval 1.085-3.409; P = 0.023). Among the IADL subcategories, outdoor activity items such as "go out by oneself," "take a bus or train," and "shop for necessities" were more likely to change from independent to dependent during hospitalization.

CONCLUSION

IADL decline during hospitalization was associated with an increased all-cause mortality rate at one-year after discharge in elderly HF patients.

Impact of Early Ambulation on the Prognosis of Coronary Artery Bypass Grafting Patients

BACKGROUND

The effect of delayed ambulation on the outcome of coronary artery bypass grafting (CABG) remains to be clarified.

METHODS AND RESULTS

The long-term and in-hospital outcomes of 887 patients who underwent isolated CABG (455 off-pump cases, 135 urgent cases) were evaluated, with a focus on the timing of first ambulation. In-hospital mortality cases were excluded. Early ambulation (first ambulation within 3 days after operation) was achieved in 339 (38%) patients. In the multivariable logistic regression analysis, longer operation time and urgent case, EuroSCORE II, re-thoracotomy, and respiratory time were associated with delayed (≥4 days) ambulation. Delayed ambulation was associated with a high incidence of postoperative complications, such as pneumonia, and stroke (P<0.01). Following discharge, 22.2% of patients experienced major cardiac events and 13.8% died during the follow-up period (median follow-up 60 months). Cox hazards analysis revealed that delayed ambulation was associated with long-term adverse events (hazard ratio 1.04 per day, P<0.001). With adjustment for preoperative factors, the estimated future risk of adverse events was found to be increased day-by-day during the delay until initial ambulation.

CONCLUSIONS

In isolated CABG patients, delayed ambulation was associated with poor outcomes, even in the long-term period. The results support the current guideline recommending early ambulation protocol after cardiac surgery.

Dysphagia is an independent predictor of hospital-acquired disability in older patients with heart failure: a propensity score-matched analysis : Predictors of HAD in older HF patients

This study aims to identify the relationship between dysphagia and developing hospital-acquired disability (HAD) in older patients with heart failure (HF). This single-center retrospective cohort study included 360 patients (median age, 84 years: 58.1% female, 41.9% male) who had undergone rehabilitation and were aged 65 years and older. Patients were divided into dysphagia and non-dysphagia groups and compared based on the Functional Oral Intake Scale score. HAD was defined as a decline in the Barthel Index score (indication of daily activity levels) at discharge relative to that before admission. The relationship between dysphagia and HAD was analyzed using bivariate analysis after adjusting for age, sex, body mass index, medical history, clinical and laboratory data, short physical performance battery (SPPB), and cognitive function at the start of rehabilitation, using propensity score matching. HAD was observed in 38.1% of the patients. Patients with dysphagia were significantly older, and had lower body mass index and physical and cognitive function than those without. After propensity score matching, the prevalence of HAD was significantly higher in the dysphagia group than in the non-dysphagia group (61.9% vs. 42.9%, P = 0.032). Dysphagia at the start of rehabilitation was an independent predictor of HAD. The results of this study may contribute to risk stratification of HAD.

Association between hospital acquired disability and post-discharge mortality in patients after living donor liver transplantation

BACKGROUND

Hospital-acquired disability (HAD) in patients who undergo living donor liver transplantation (LDLT) is expected to worsen physical functions due to inactivity during hospitalization. The aim of this study was to explore whether a decline in activities of daily living from hospital admission to discharge is associated with prognosis in LDLT patients, who once discharged from a hospital.

METHODS

We retrospectively examined the relationship between HAD and prognosis in 135 patients who underwent LDLT from June 2008 to June 2018, and discharged from hospital once. HAD was defined as a decline of over 5 points in the Barthel Index as an activity of daily living assessment. Additionally, LDLT patients were classified into four groups: low or high skeletal muscle index (SMI) and HAD or non-HAD. Univariate and multivariate Cox proportional hazard models were used to evaluate the association between HAD and survival.

RESULTS

HAD was identified in 47 LDLT patients (34.8%). The HAD group had a significantly higher all-cause mortality than the non-HAD group (log-rank: p < 0.001), and in the HAD/low SMI group, all-cause mortality was highest between the groups (log-rank: p < 0.001). In multivariable analysis, HAD was an independent risk factor for all-cause mortality (hazard ratio [HR]: 16.54; P < 0.001) and HAD/low SMI group (HR: 16.82; P = 0.002).

CONCLUSION

HAD was identified as an independent risk factor for all-cause mortality suggesting that it could be a key component in determining prognosis after LDLT. Future larger-scale studies are needed to consider the overall new strategy of perioperative rehabilitation, including enhancement of preoperative physiotherapy programs to improve physical function.

Improvements in sleep quality and fatigue are associated with improvements in functional recovery following hospitalization in older adults

Study objectives

Poor sleep quality, a frequent problem in older adults, has been shown to be associated with reduced physical function and wellbeing. However, little is known about the relationship between sleep quality and the recovery of physical function following hospitalization. Thus, we conducted this study to examine the association between sleep quality and functional recovery after an acute hospitalization in community dwelling older adults.

Methods

Older adult patients (N = 23, mean age = 74 ± 9 years) were recruited during an acute hospitalization (average length of stay 3.9 days) with a cardiovascular (56%), pulmonary (22%), or metabolic (13%) admission diagnosis. Objective physical function was measured using the Short Physical Performance Battery (SPPB) and self-reported function was assessed with Katz Index of Independence in Activities of Daily Living (ADL) and Lawton Instrumental Activities of Daily Living Scale (IADL). Sleep quality was measured using Pittsburgh Sleep Quality Index (PSQI) global score and Iowa Fatigue Score (IFS). Testing was performed prior to discharge (baseline) and 4-weeks post-discharge (follow-up).

Results

Regression models showed PSQI Subjective Sleep Quality change scores from baseline to 4-week follow-up predicted a change in ADL (β = -0.22); PSQI Use of Sleep Medications change scores predicted a change in SPPB Total (β = 1.62) and SPPB Chair Stand (β = 0.63); IFS change scores predicted SPPB Total (β = -0.16) and SPPB Chair Stand performance (β = -0.07) change scores.

Conclusions

For older adults, changes in sleep medication use, daytime dysfunction, and fatigue were associated with improvements in functional recovery (including physical performance and independence) from acute hospitalization to 4-week follow-up. These results suggest that interventions focused on improving sleep quality, daytime consequences, and fatigue might help enhance physical functioning following hospitalization.

Hospital-associated disability and hospitalization costs for acute heart failure stratified by body mass index- insight from the JROAD/JROAD-DPC database

BACKGROUND

The impact of body mass index (BMI) on hospital mortality in patients with acute heart failure has been well documented in Asian populations. However, the relationship between BMI, hospital-associated disability (HAD), and hospitalization costs in patients with heart failure is poorly understood. This study aimed to explore the impact of BMI on HAD and hospitalization costs for acute heart failure in Japan.

METHODS

From April 2012 to March 2020, the Japanese Registry of All Cardiac and Vascular Disease Diagnosis Procedure Combination (JROAD-DPC) database was used to identify patients with acute heart failure. All patients were categorized into five groups according to the World Health Organization Asian BMI criteria. The hospitalization costs and HAD were evaluated.

RESULTS

Among the 238,160 eligible patients, 15.7% were underweight, 42.2% were normal, 16.7% were overweight, 19.3% were obese I, and 6.0% were obese II, according to BMI. The prevalence of HAD was 7.43% in the total cohort, and the risk of HAD increased with a lower BMI. Restricted cubic spline analysis showed a U-shaped relationship between BMI and hospitalization costs for all ages. Furthermore, developing HAD was associated with greater costs compared with non-HAD, regardless of BMI category.

CONCLUSIONS

We found that the lower the BMI, the higher the incidence of HAD. A U-shaped association was confirmed between BMI and hospitalization costs, indicating that hospitalization costs increased for both lower and higher BMI regardless of age. BMI could be an important and informative risk stratification tool for functional outcomes and economic burdens.

Effectiveness and Approach of Rehabilitation in Patients With Acute Heart Failure: A Review

Acute heart failure is associated with high mortality and frequent rehospitalization, resulting in enormous healthcare costs and declining physical function, activities of daily living, and quality of life. Cardiac rehabilitation has been recommended as one of the non-pharmacologic treatments for patients with heart failure. However, much of the evidence for cardiac rehabilitation interventions reported to date has been limited to chronic heart failure. In recent years, the effectiveness of rehabilitation intervention in patients with acute heart failure has been reported, led by the Rehabilitation Therapy in Older Acute Heart Failure Patients (REHAB-HF) trial. This review overviews the recent evidence of rehabilitation in patients with acute heart failure.

Discharge disposition and 1-year readmission in acute-phase hospitalized patients with heart failure: a retrospective observational multi-center study

Patients hospitalized for acute heart failure (HF) tend to experience declines in physical function and activities of daily living (ADL) due to bed rest and restricted mobilization. This could result in some patients being transferred to rehabilitation hospitals. This study aims to examine the relationship between discharge disposition and 1-year readmission and mortality rates in HF patients. Nine hundred fifty six consecutive HF patients who were hospitalized for acute decompensated HF and underwent rehabilitation were divided into two groups: home (returned home) or transfer (transferred to rehabilitative or long-term care hospital units due to decline in physical function and/or ADL) groups. The primary and secondary outcomes were 1-year readmission and mortality rates after discharge, respectively. Of the 956 patients, 8.6% (n = 82) were transferred to rehabilitative or long-term care hospital units. Over a 1-year follow-up period, all-cause and HF readmission rates were 50.1% (n = 479) and 27.2% (n = 260), respectively. The transfer group had significantly lower readmission rates compared to home group after adjusting for the pre-existing risk factors (hazard ratio for all-cause and HF readmission: 0.600 and 0.552, 95% CI 0.401-0.897 and 0.314-0.969; P = 0.013 and P = 0.038, respectively). There was no significant relationship between discharge disposition and all-cause mortality rate. Low ADL defined as Barthel index < 60 points was identified as a predictor of all-cause and HF readmission among the home group (odds ratio for all-cause and HF readmission rates: 2.156 and 1.847, 95% CI 1.026-4.531 and 1.036-2.931; P = 0.043 and P = 0.037, respectively). This multi-center study demonstrated that HF patients transferred to rehabilitative or long-term care hospital units after an acute hospitalization had a significantly decreased 1-year all-cause and HF readmission rates compared to patients who returned to their home. These findings may help in selecting a discharge disposition for older HF patients with ADL decline.

Associations of body mass index and hospital-acquired disability with post-discharge mortality in older patients with acute heart failure

OBJECTIVES

To investigate the effect of hospital-acquired disability (HAD) on all-cause mortality after discharge according to the body mass index (BMI) in older patients with acute decompensated heart failure.

METHODS

We included 408 patients aged ≥ 65 years who were hospitalized for acute decompensated heart failure and had undergone an acute phase of cardiac rehabilitation at the Sakakibara Heart Institute between April 2013 and September 2015 (median age: 82 years, interquartile range (IQR): 76-86; 52% male). Patients were divided into three groups based on BMI at hospital admission: underweight (< 18.5 kg/m²), normal weight (18.5 to 25 kg/m²), and overweight (≥ 25 kg/m²). HAD was defined as a decrease of at least five points at discharge compared to before hospitalization according to the Barthel Index.

RESULTS

The median follow-up period was 475 (IQR: 292-730) days, and all-cause mortality during the follow-up period was 84 deaths (21%). According to multivariate Cox regression analysis, being underweight (HR: 1.941, 95% CI: 1.134-3.321,P = 0.016) or overweight (HR: 0.371, 95% CI: 0.171-0.803,P = 0.012), with normal BMI as the reference, and HAD (HR: 1.857, 95% CI: 1.062-3.250,P = 0.030) were independently associated with all-cause mortality. Patients with HAD exhibited a significantly lower cumulative survival rate in the underweight group (P = 0.001) and tended to have a lower cumulative survival rate in the normal weight group (P = 0.072). HAD was not significantly associated with cumulative survival in the overweight group (P = 0.392).

CONCLUSIONS

BMI and HAD independently predicted all-cause mortality after discharge in older patients with acute decompensated heart failure. Furthermore, HAD was significantly associated with higher all-cause mortality after discharge, especially in the underweight group.

Efficacy and Safety of Acute Phase Intensive Electrical Muscle Stimulation in Frail Older Patients with Acute Heart Failure: Results from the ACTIVE-EMS Trial

As frailty in older patients with acute heart failure (AHF) has an adverse effect on clinical outcomes, the addition of electrical muscle stimulation (EMS) to exercise-based early rehabilitation may improve the effects of treatment. Post hoc analysis was performed on a randomized controlled study for clinical outcomes and prespecified subgroups (ACTIVE-EMS: UMIN000019551). In this trial, 31 AHF patients aged ≥ 75 years with frailty (Short Physical Performance Battery [SPPB] score 4–9) were randomized 1:1 to receive treatment with an early rehabilitation program only (n = 16) or early rehabilitation with add-on EMS therapy (n = 15) for 2 weeks. Changes in physical function and cognitive function between baseline and after two weeks of treatment were assessed. There were no adverse events during the EMS period. The EMS group showed significantly greater changes in quadriceps’ isometric strength and SPPB compared to the control group, and EMS therapy showed uniform effects in the prespecified subgroups. There were no significant differences in the changes in other indexes of physical function and cognitive function between groups. There was no significant difference in the rate of heart failure hospitalization at 90 days between groups. In conclusion, older AHF patients with frailty showed greater improvement in lower extremity function with the addition of EMS therapy to early rehabilitation without adverse events.

Protocol for a multicentre, prospective observational cohort study in Japan: association among hospital-acquired disability, regular exercise and long-term care dependency in older patients after cardiac surgery

INTRODUCTION

Cardiac surgery for older patients, postoperative functional decline and the need for long-term care have received increasing attention as essential outcomes in recent years. Therefore, prevention of functional decline and long-term care dependency after cardiac surgery are important; however, our current understanding of postoperative functional trajectory and effects of postoperative regular exercise on long-term functional decline and long-term care dependency is limited. Therefore, we will conduct a multicentre, prospective cohort study to (1) examine the effect of hospital-acquired disability on long-term functional decline and long-term care dependency and (2) investigate the favourable effect of postoperative regular exercise on long-term functional decline and long-term care dependency in older patients after cardiac surgery.

METHODS AND ANALYSIS

We designed a prospective, multicentre cohort study to enrol older patients aged≥65 years undergoing elective coronary artery bypass graft or valve surgery. We will conduct medical record reviews to collect data on patient demographics, comorbidities, operative details, progression of in-hospital postoperative cardiac rehabilitation and functional trajectory from a few days before cardiac surgery to the day before hospital discharge. They will be followed up for 2 years to obtain information on their health status including functional status, regular exercise and clinical events by mail. Primary endpoints of this study are long-term functional decline and long-term care dependency after cardiac surgery. Secondary endpoints are readmission due to cardiac events or all-cause mortality.

ETHICS AND DISSEMINATION

The study protocol was approved by the Ethics Committee of the Department of Physical Therapy, Faculty of Health Science, Juntendo University, and of each collaborating hospital. We obtained written informed consent from all study participants after the description of the study procedures. Publication of the study results is anticipated in 2025.

Clinical Characteristics of Older Heart Failure Patients With Hospital-Acquired Disability: A Preliminary, Single-Center, Observational Study

Background

This study investigated the clinical factors related to hospital-acquired disability (HAD) among 70 patients (median age, 78 years; interquartile range (IQR), 78 - 83) who were hospitalized for heart failure (HF) at Ayase Heart Hospital between December 2019 and October 2020.

Methods

HAD was defined as a ≥ 5-point decrease in Barthel Index (BI) scores from admission to discharge. Twenty-nine HF patients (41%) developed HAD after admission.

Results

Compared to the non-HAD group, the HAD group had higher Kihon Checklist scores (14 points (IQR, 11 - 17) vs. 9 points (IQR, 6 - 13); P < 0.01) and prevalence of multi-faceted frailty (90% vs. 29%; P < 0.01), a longer urinary-catheter-placement period (3 days (IQR, 1 - 5] vs. 1 day (IQR, 0 - 2), P < 0.05), less daily number of steps (457 steps (IQR, 301 - 997) vs. 1,692 steps (IQR, 1,227 - 2,418); P < 0.01), and moderate-intensity physical activity time (0 min (IQR, 0 - 2] vs. 1 min (IQR, 0 - 3); P < 0.05).

Conclusion

In conclusion, lower physical function and general physical activity and longer urinary-catheter-placement are associated with HAD.

Prognostic impact of hospital-acquired disability in elderly patients with heart failure

Aims

Functional decline is associated with worse outcomes in patients with elderly heart failure (HF), but little is known about the prognostic impact of hospital‐acquired disability (HAD) during hospital stay after acute HF. The present study examines the prognostic significance of HAD in the prediction of all‐cause mortality in elderly patients who admitted for acute HF.

Methods and results

This retrospective study was performed in 1941 elderly patients aged ≥65 years or older from the cardiovascular physiotherapy for acute HF patients in the Tokyo metropolitan area registry and excluded those who died in hospital. HAD was defined as any decline in the Barthel index (BI) before discharge compared with the BI within 1 month before hospital admission. The primary outcome of this study was all‐cause death and HF readmission. A total of 565 (29%) deaths and 789 (41%) HF readmission occurred over a median follow‐up period of 1.7 years. A total of 476 patients (25%) had HAD during hospital stay after acute HF. In multivariable analysis, HAD predicted all‐cause death [hazard ratio (HR): 1.772; 95% confidence interval (CI): 1.450–2.167; P < 60; 0.001] and with risk of HF readmission (HR: 1.193; 95% CI: 1.005–1.416; P = 0.043) after adjusting for the Meta‐analysis Global Group in Chronic Heart Failure risk score.

Conclusions

Hospital‐acquired disability is associated with an increased risk of all‐cause death and readmission for HF in elderly patients with acute HF.
