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.

The barriers to interprofessional care for cancer cachexia among Japanese healthcare providers: A nationwide survey.

BACKGROUND: Cancer cachexia is a severe complication of advanced malignancy, with few therapeutic options. To promote interprofessional care for cancer cachexia, healthcare providers' needs should be addressed in detail. This pre-planned subgroup analysis of the Global Educational Needs Evaluation: a systemic interprofessional study in cancer cachexia (GENESIS-CC) survey aimed to identify barriers to interprofessional care of cancer cachexia in Japan. METHODS: A nationwide survey was electronically conducted for healthcare providers in oncological or general healthcare facilities from January to March 2021 in Japan. The Japanese Regional Advisory Board developed a barrier scoring system with 33 from the 58 original survey items to quantify six domains of barriers: (1) lack of confidence, (2) lack of knowledge, (3) barriers in personal practice, (4) barriers in perception, (5) barriers in team practice and (6) barriers in education. The largest possible barrier score was set at 100 points. We compared the scores by profession. RESULTS: A total of 1227 valid responses were obtained from 302 (24.6%) physicians, 252 (20.5%) pharmacists, 236 (19.2%) nurses, 218 (17.8%) dietitians, 193 (15.7%) rehabilitation therapists and 26 (2.0%) other professionals. Overall, 460 (37.5%) were not very or at all confident about cancer cachexia care, 791 (84.1%) agreed or strongly agreed that care was influenced by reimbursement availability and 774 (81.9%) did not have cancer cachexia as a mandatory curriculum. The largest mean barrier score (± standard deviation) was 63.7 ± 31.3 for education, followed by 55.6 ± 21.8 for team practice, 43.7 ± 32.5 for knowledge, 42.8 ± 17.7 for perception and 36.5 ± 16.7 for personal practice. There were statistically significant interprofessional differences in all domains (P < 0.05), especially for pharmacists and nurses with the highest or second highest scores in most domains. CONCLUSIONS: There is a need to improve the educational system and team practices of cancer cachexia for most Japanese healthcare providers, especially pharmacists and nurses. Our study suggests the need to reform the mandatory educational curriculum and reimbursement system on cancer cachexia to promote interprofessional care for cancer cachexia in Japan.

Effect of in-patient cardiac rehabilitation at rehabilitation hospital for cardiology patients: two-center trial.

The effectiveness of cardiac rehabilitation (CR) in patients with cardiovascular disease requiring continuous CR from an acute care hospital to a convalescent rehabilitation hospital is unknown. Therefore, we compared the effect of CR in a rehabilitation hospital for patients with cardiovascular disease with that of those who underwent cardiovascular surgery. Sixty-nine consecutive patients were admitted to two rehabilitation hospitals for CR. Patients were classified by primary disease into two groups: patients with cardiovascular disease (cardiology group, 26 patients) and patients who underwent cardiovascular surgery (surgery group, 43 patients). Clinical information, physical function, cognitive function, activities of daily living (ADL), quality of life (QOL), amount of CR, and length of hospital stay were compared between the two groups. Compared with clinical features, age was significantly higher in the cardiology group (P < 0.001), and the preadmission Barthel index was significantly lower in the cardiology group (P = 0.025). Physical function at the time of transfer was significantly lower in the cardiology group than in the surgery group for the short physical performance battery (P < 0.001), gait speed (P = 0.005), and 6-min walking distance (P = 0.042). No significant difference was found in the amount of CR performed or the length of hospital stay, and no interaction effects were observed in improvements in physical function, exercise tolerance, or QOL. In conclusion, in rehabilitation hospitals, patients with cardiovascular disease were older, had lower preadmission ADL, and had lower a physical function at transfer than those who underwent cardiovascular surgery, but CR improved physical function and QOL to the same extent. The results suggest that the recovery of patients with cardiovascular disease may be similar to those who undergo cardiovascular surgery.

Association of Postexercise Vagal Dysfunction With Protein-Energy Wasting and Noncardiovascular Outcomes in Patients Receiving Hemodialysis: A Retrospective Cohort Study.

OBJECTIVE: Postexercise vagal dysfunction is linked to noncardiovascular mortality in hemodialysis patients, but the mechanism is unknown. This study aimed to determine the association of cardiovagal neuropathy with systemic inflammation, protein-energy wasting, and noncardiovascular hospitalization. METHODS: This 2-center retrospective cohort study analyzed data from 280 hemodialysis patients who underwent exercise test. Patients were assessed for heart rate (HR) recovery (bpm) for 1 minute after exercise, a marker of vagal function, and were divided into 3 categories (Low: ≤ 6, Mid: 7-11, High: ≥ 12 bpm). We followed 1-year changes in the systemic inflammation-based prognostic score (Glasgow Prognostic Score [GPS]), body weight, and creatinine generation rate (CGR), an indicator of muscle mass, as well as 2-year hospitalization. RESULTS: The HR recovery category was associated with serum C-reactive protein and albumin levels and GPS. After 1 year, the low HR recovery category was associated with worsening in GPS (low, 0 [0-0.5]; mid, 0 [0-1]; high, 0 [0-0]), weight (low, 100.0 [96.1-102.5]; mid, 101.3 [98.9-105.0]; high, 100.5 [98.2-102.9]%), and CGR (low, 97.0 [88.5-111.4]; mid, 110.2 [90.9-124.8]; high, 106.2 [95.5-115.5]%), and the correlations with GPS and CGR remained consistent after adjusting for confounders such as exercise capacity and hospitalization during the follow-up period. There were 117 patients hospitalized. Compared to the high HR recovery category, the mid (hazard ratio: 1.8, 95% confidence interval [CI]: 1.1-3.1, P = .02) and low (hazard ratio: 2.4, 95% CI: 1.5-4.0, P = .001) categories were independently associated with an increased risk of all-cause hospitalization. For noncardiovascular disease hospitalization, the low HR recovery category was independently associated with increased risk of hospitalization (hazard ratio: 2.1, 95% CI: 1.2-3.7, P = .007). CONCLUSIONS: Vagal neuropathy in this population can contribute to adverse outcomes associated with systemic inflammation and protein-energy wasting.

Comparison of intradialytic continuous and interval training on hemodynamics and dialysis adequacy: A crossover randomized controlled trial.

AIM: Circulating blood volume (BV) during exercise changes depending on the intensity and duration, and post-exercise hypotension is observed after continuous exercise. We investigated the safety and efficacy of both interval and continuous IDE at anaerobic threshold (AT) levels with respect to hemodynamic stability and dialysis efficiency. METHODS: In this crossover randomized controlled trial, 16 patients on haemodialysis were subjected to three trial arms, including non-IDE, interval-IDE, and continuous-IDE arms. Systolic blood pressure (SBP), BV, and ultraviolet absorbance - an indicator of dialysis efficiency - were continuously measured, and each change was compared between the three arms by two-way analysis of variance. RESULTS: Continuous IDE decreased SBP from post-exercise to the end of dialysis compared with baseline (pre 142.8 ± 19.0 vs. post 127.5 ± 24.5 mmHg, p = .02), whereas interval IDE maintained better SBP levels post-exercise (pre 139.9 ± 17.1 vs. post 140.1 ± 15.8 mmHg, p = 1.0) than continuous IDE (non-IDE 133.2 ± 19.9 vs. interval 140.1 ± 15.8 vs. continuous 127.5 ± 24.5 mmHg, p = .04). Moreover, interval IDE caused less tiredness and few symptoms (p < .05), despite reaching higher intensity than continuous IDE (p = .001). The BV of each IDE arm decreased during exercise and recovered post-exercise to the same level as non-IDE. Ultraviolet absorbance was not different between each arm (p = .16). CONCLUSION: AT-level interval IDE maintains better hemodynamic stability from post-exercise to the end of dialysis and may represent a novel approach that can be effectively performed with fewer symptoms.

Japanese Clinical Practice Guidelines for Rehabilitation in Critically Ill Patients 2023 (J-ReCIP 2023).

Providing standardized, high-quality rehabilitation for critically ill patients is a crucial issue. In 2017, the Japanese Society of Intensive Care Medicine (JSICM) promulgated the "Evidence-Based Expert Consensus for Early Rehabilitation in the Intensive Care Unit" to advocate for the early initiation of rehabilitations in Japanese intensive care settings. Building upon this seminal work, JSICM has recently conducted a rigorous systematic review utilizing the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) methodology. This endeavor resulted in the formulation of Clinical Practice Guidelines (CPGs), designed to elucidate best practices in early ICU rehabilitation. The primary objective of this guideline is to augment clinical understanding and thereby facilitate evidence-based decision-making, ultimately contributing to the enhancement of patient outcomes in critical care settings. No previous CPGs in the world has focused specifically on rehabilitation of critically ill patients, using the GRADE approach. Multidisciplinary collaboration is extremely important in rehabilitation. Thus, the CPGs were developed by 73 members of a Guideline Development Group consisting of a working group, a systematic review group, and an academic guideline promotion group, with the Committee for the Clinical Practice Guidelines of Early Mobilization and Rehabilitation in Intensive Care of the JSICM at its core. Many members contributed to the development of the guideline, including physicians and healthcare professionals with multiple and diverse specialties, as well as a person who had been patients in ICU. Based on discussions among the group members, eight important clinical areas of focus for this CPG were identified. Fourteen important clinical questions (CQs) were then developed for each area. The public was invited to comment twice, and the answers to the CQs were presented in the form of 10 GRADE recommendations and commentary on the four background questions. In addition, information for each CQ has been created as a visual clinical flow to ensure that the positioning of each CQ can be easily understood. We hope that the CPGs will be a useful tool in the rehabilitation of critically ill patients for multiple professions.

Diagnosis and outcomes of cachexia in Asia: Working Consensus Report from the Asian Working Group for Cachexia.

Chronic diseases often lead to metabolic disorders, causing anabolic resistance and increased energy consumption, which result in cachexia. Cachexia, in turn, can lead to major clinical consequences such as impaired quality of life, shortened life expectancy, and increased healthcare expenditure. Existing international diagnostic criteria for cachexia employ thresholds derived from Western populations, which may not apply to Asians due to differing body compositions. To address this issue, the Asian Working Group for Cachexia (AWGC) was initiated. The AWGC comprises experts in cachexia research and clinical practice from various Asian countries and aims to develop a consensus on diagnostic criteria and significant clinical outcomes for cachexia in Asia. The AWGC, composed of experts in cachexia research and clinical practice from several Asian countries, undertook three-round Delphi surveys and five meetings to reach a consensus. Discussions were held on etiological diseases, essential diagnostic items for cachexia, including subjective and objective symptoms and biomarkers, and significant clinical outcomes. The consensus highlighted the importance of multiple diagnostic factors for cachexia, including chronic diseases, either or both weight loss or low body mass index, and at least one of the following: anorexia, decreased grip strength (<28 kg in men and <18 kg in women), or elevated C-reactive protein levels (>5 mg/L [0.5 mg/dL]). The AWGC proposed a significant weight change of 2% or more over a 3-6 month period and suggested a tentative cut-off value of 21 kg/m2 for low body mass index in diagnosing cachexia. Critical clinical outcomes were determined to be mortality, quality of life as assessed by tools such as EQ-5D or the Functional Assessment of Anorexia/Cachexia Therapy, and functional status as measured by the Clinical Frailty Scale or Barthel Index, with significant emphasis on patient-reported outcomes. The AWGC consensus offers a comprehensive definition and user-friendly diagnostic criteria for cachexia, tailored specifically for Asian populations. This consensus is set to stimulate future research and enhance the multidisciplinary approach to managing cachexia. With plans to develop further guidelines for the optimal treatment, prevention, and care of cachexia in Asians, the AWGC criteria are expected to drive research across chronic co-morbidities and cancer in Asia, leading to future refinement of diagnostic criteria.

Diaphragm Dysfunction and ICU-Acquired Weakness in Septic Shock Patients with or without Mechanical Ventilation: A Pilot Prospective Observational Study.

Sepsis is a risk factor for diaphragm dysfunction and ICU-acquired weakness (ICU-AW); however, the impact of mechanical ventilation (MV) on these relationships has not been thoroughly investigated. This study aimed to compare the incidence of diaphragm dysfunction and ICU-AW in patients with septic shock, with and without MV. We conducted a single-center prospective observational study that included consecutive patients diagnosed with septic shock admitted to the ICU between March 2021 and February 2022. Ultrasound measurements of diaphragm thickness and manual measurements of limb muscle strength were repeated after ICU admission. The incidences of diaphragm dysfunction and ICU-AW, as well as their associations with clinical outcomes, were compared between patients with MV and without MV (non-MV). Twenty-four patients (11 in the MV group and 13 in the non-MV group) were analyzed. At the final measurements in the MV group, eight patients (72.7%) had diaphragm dysfunction, and six patients (54.5%) had ICU-AW. In the non-MV group, 10 patients (76.9%) had diaphragm dysfunction, and three (23.1%) had ICU-AW. No association was found between diaphragm dysfunction and clinical outcomes. Patients with ICU-AW in the MV group had longer ICU and hospital stays. Among patients with septic shock, the incidence of diaphragm dysfunction was higher than that of ICU-AW, irrespective of the use of MV. Further studies are warranted to examine the association between diaphragm dysfunction and clinical outcomes.

Safety and Feasibility of Tele-Cardiac Rehabilitation Using Remote Biological Signal Monitoring System: A Pilot Study.

Background: Cardiac rehabilitation (CR) is categorized as a class I recommendation in the guidelines for the management of patients with cardiovascular disease (CVD). However, the penetration rate of outpatient CR is low in Japan. We designed a pilot study to evaluate the safety and feasibility of tele-CR using a remote biological signal monitoring system. Methods: A total of nine patients (median aged 70.0 (66.0 - 76.0) years (male = 6) with CVD who participated in phase II CR for 1 month under the exercise prescription using the cardiopulmonary exercise test (CPET) were analyzed. They participated in the tele-CR program with a remote biological signal monitoring system (Nipro HeartLineTM, Osaka, Japan, and Duranta, Miyagi, Japan) in the CR room and were instructed by the CR staff from a separate room in the hospital. We evaluated the occurrence and degree of remote biological signal monitoring defects as safety evaluation items, i.e., whether the patients could set the remote biological signal monitoring equipment, as a feasibility evaluation item during a 3-month period. We also performed CPET at the baseline and follow-up. Following the 3-month tele-CR program, a total of 122 remote CR programs were performed using the remote biological signal monitoring system. Results: No patient experienced a lack of remote biological signal monitoring during exercise therapy. Significant improvement was noted in the exercise capacity, as assessed using the cardiopulmonary test (from 19.5 (16.7 - 20.2) mL/kg/min to 21.1 (17.3 - 22.8) mL/kg/min, P = 0.01, age ratio from 86% (75-96%) to 99% (78-104%), P = 0.01). One patient required support using the remote biological signal monitoring system, including information technology literacy. Conclusions: This study suggests the safety and feasibility of tele-CR using the remote biological signal monitoring system. However, further investigations are required to explore the suitability, effects, and cost-effectiveness of tele-CR as an alternative to center-based CR in the future.

Relationship Between Skeletal Muscle Quality and Hospital-Acquired Disability in Patients With Sepsis Admitted to the ICU: A Pilot Study.

Early risk assessment of functional decline in patients with sepsis is clinically challenging. Recently, there is increasing interest in the nonvolitional evaluation of skeletal muscle quality. OBJECTIVES: The aim of this study was to assess the relationship between skeletal muscle quality and functional decline after intensive care. DESIGN SETTING AND PARTICIPANTS: This pilot study was a single-center prospective observational study conducted from March 2021 to February 2022. We included consecutive patients with sepsis who were admitted to our ICU. MAIN OUTCOMES AND MEASURES: The primary outcome was hospital-acquired disability (HAD), which is defined as a decrease in the Barthel index score of at least 5 points from pre-hospital to hospital discharge. Muscle quality was assessed by: 1) muscle echogenicity with ultrasound and 2) phase angle (PhA) with bioelectrical impedance analysis, both of which were measured on ICU days less than 3, 3-5, 5-7, 7-10, and 10-14. We compared longitudinal changes in muscle echogenicity and PhA between the HAD and non-HAD groups using two-way repeated measures analysis of variance with mixed models. RESULTS: Among the 22 patients, 7 (31.8%) had HAD. Muscle echogenicity was higher in the HAD group than in the non-HAD group (p < 0.001); however, no interaction effects were found between the two groups (p = 0.189). PhA showed a main effect on each evaluation day in patients (p = 0.040) and a significant interaction effect between the groups, including an early decreased pattern in the HAD group (p = 0.036). CONCLUSIONS AND RELEVANCE: Higher muscle echogenicity and a decreased PhA pattern are related to HAD. Noninvasive assessment of muscle quality using ultrasound and bioelectrical impedance analysis may be useful in predicting the functional prognosis of patients with sepsis.

Association between hospital-acquired functional decline and 2-year readmission or mortality after cardiac surgery in older patients: a multicenter, prospective cohort study.

BACKGROUND: Hospital-acquired functional decline (HAFD) is a new predictor of poor prognosis in hospitalized older patients. AIMS: We aimed to assess the impact of HAFD on the prognosis of older cardiac surgical patients 2 years after discharge. METHODS: This multicenter prospective cohort study assessed 293 patients with cardiac disease aged ≥ 65 years who underwent cardiac surgery at 7 Japanese hospitals between June 2017 and June 2018. The primary endpoint was the composite outcome of cardiovascular-related readmission and all-cause mortality 2 years after discharge. HAFD was assessed using the total Short Physical Performance Battery at hospital discharge. RESULTS: The primary outcome was observed in 17.3% of the 254 included patients, and HAFD was significantly associated with the primary outcome. Female sex (hazard ratio [HR], 2.451; 95% confidence interval [CI] 1.232-4.878; P = 0.011), hemoglobin level (HR, 0.839; 95% CI 0.705-0.997; P = 0.046), preoperative frailty (HR, 2.391; 95% CI 1.029-5.556; P = 0.043), and HAFD (HR, 2.589; 95% CI 1.122-5.976; P = 0.026) were independently associated with the primary outcome. The incidence rate of HAFD was 22%, with female sex (odds ratio [OR], 1.912; 95% CI 1.049-3.485; P = 0.034), chronic obstructive pulmonary disease (OR, 3.958; 95% CI 1.413-11.086; P = 0.009), and the time interval (days) between surgery and the start of ambulation (OR, 1.260, 95% CI 1.057-1.502; P = 0.010) identified as significant factors. DISCUSSION: HAFD was found to be an independent prognostic determinant of the primary outcome 2 years after discharge. CONCLUSION: HAFD prevention should be prioritized in the hospital care of older cardiac surgery patients.

Factors Related to Hospitalisation-Associated Disability in Patients after Surgery for Acute Type A Aortic Dissection: A Retrospective Study.

The in-hospital mortality rate among patients after surgery for acute type A aortic dissection (ATAAD) has improved chronologically. However, the relationship between the incidence of hospitalisation-associated disability (HAD) and acute cardiac rehabilitation in patients after surgery for ATAAD has not been reported. Therefore, this study evaluated factors related to HAD in patients after surgery for ATAAD. This single-centre retrospective observational study included 483 patients who required emergency surgery for ATAAD. HAD occurred in 104 (21.5%) patients following cardiovascular surgery. Factors associated with HAD were age (odds ratio [OR], 1.05; 95% confidence interval [CI], 1.02-1.09; p = 0.001), noninvasive positive pressure ventilation (NPPV; OR, 2.15; 95% CI, 1.10-4.19; p = 0.025), postoperative delirium (OR, 2.93; 95% CI, 1.60-5.37; p = 0.001), and timing of walking onset (OR, 1.29; 95% CI, 1.07-1.56; p = 0.008). Furthermore, a late walking onset was associated with a higher risk of developing HAD and more severe functional decline. Early rehabilitation based on appropriate criteria has possibility of preventing HAD.

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.

The Potential Application of Commercially Available Active Video Games to Cardiac Rehabilitation: Scoping Review.

BACKGROUND: Commercially available active video games (AVGs) have recently been used for rehabilitation in some specific patient populations but rarely in those with cardiovascular disease (CVD). Commercially available AVGs are designed to increase motivation for continuous play, which could be applicable to the long-term cardiac rehabilitation process. OBJECTIVE: The objective of this scoping review was to assess the effectiveness of AVG-induced physical exercise, safety management, and patient adherence by applying commercially available AVGs to cardiac rehabilitation. METHODS: Four databases (CINAHL, MEDLINE, PubMed, and SPORTDiscus) were searched for all years up to August 12, 2020. Articles were retained if they were written in English, included patients with CVD who were aged 18 years or older, and used AVGs as part of a physical exercise program. The included studies were then evaluated from the viewpoints of effectiveness as physical exercise, safety, and adherence management. RESULTS: Among 120 nonduplicate articles reviewed, 5 (4.2%) were eligible for inclusion, of which 3 (2.5%) were reported by the same research group. The AVG consoles used were Xbox Kinect and Nintendo Wii, and sports-related programs were adopted for the intervention. No adverse cardiac events occurred in the identified studies, and dropout rates tended to be low. CONCLUSIONS: AVGs appear to be safe and feasible for promoting an active lifestyle in patients with CVD. However, the effectiveness of AVGs alone as a therapeutic exercise to improve physical function may be limited.

Quality Indicators in Patient Referral Documents for Heart Failure in Japan.

This study examined quality indicators (QIs) for heart failure (HF) in patients' referral documents (PRDs).We conducted a nationwide questionnaire survey to identify information that general practitioners (GPs) would like hospital cardiologists (HCs) to include in PRDs and that HCs actually include in PRDs. The percentage of GPs that desired each item included in PRDs was converted into a deviation score, and items with a deviation score of ≥ 50 were defined as QIs. We rated the quality of PRDs provided by HCs based on QI assessment.We received 281 responses from HCs and 145 responses from GPs. The following were identified as QIs: 1) HF cause; 2) B-type natriuretic peptide (BNP) or N-terminal pro-BNP concentration; 3) left ventricular ejection fraction or echocardiography; 4) body weight; 5) education of patients and their families on HF; 6) physical function, and 7) functions of daily living. Based on QI assessment, only 21.7% of HCs included all seven items in their PRDs. HCs specializing in HF and institutions with many full-time HCs were independently associated with including the seven items in PRDs.The quality of PRDs for HF varies among physicians and hospitals, and standardization is needed based on QI assessment.

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.

Association of cardiac autonomic neuropathy assessed by heart rate response during exercise with intradialytic hypotension and mortality in hemodialysis patients.

The heart rate (HR) reflects the dynamic behavior of the autonomic nervous system, and HR profiles during the exercise test provide prognostic information. However, there are no reports of these factors in hemodialysis patients. Data from 256 patients (mean 68.8 years old) who underwent an exercise test were statistically analyzed. Patients were evaluated for the percent HR reserve from HR at peak exercise, HR recovery for one minute after peak exercise, and exercise capacity, as well as intradialytic hypotension (IDH). The prevalence of chronotropic incompetence (96.1%), defined as under 80% HR reserve, and abnormal HR recovery (60.5%), defined as under 12 beats, were very common. Eighty-four deaths occurred during the follow-up period (median, 3.8 years). A slow HR recovery under 7 beats was associated with IDH after adjustment (odds ratio 2.7, 95% confidence interval 1.1-6.4). HR recovery under 12 beats (hazard ratio over study period 5.1, 95% confidence interval 2.5-10.5), HR reserve under 26.2% (3.4, 1.7-6.8), and IDH (1.7, 1.1-2.8) were associated with all-cause mortality after adjustment. Considering the confounding of all three variables, only HR recovery under 12 beats remained associated with the all-cause and cause-specific mortality ("cardiovascular" and "non-cardiovascular"). This association was consistent even in subgroup analyses based on the presence of diabetes and cardiovascular disease. Thus, HR profiles during the exercise can reflect potential health conditions related to cardiac autonomic neuropathy in hemodialysis patients that affect IDH and their survival.

Hospital-Acquired Functional Decline and Clinical Outcomes in Older Cardiac Surgical Patients: A Multicenter Prospective Cohort Study.

This study aimed to determine the effect of hospital-acquired functional decline (HAFD) on prognosis, 1-year post-hospital discharge, of older patients who had undergone cardiac surgery in seven Japanese hospitals between June 2017 and June 2018. This multicenter prospective cohort study involved 247 patients with cardiac disease aged ≥65 years. HAFD was defined as a decrease in the short physical performance battery at hospital discharge compared with before surgery. Primary outcomes included a composite outcome of frailty severity, total mortality, and cardiovascular readmission 1-year post-hospital discharge. Secondary outcomes were changes in the total score and sub-item scores in the Ki-hon Checklist (KCL), assessed pre- and 1-year postoperatively. Poor prognostic outcomes were observed in 33% of patients, and multivariate analysis identified HAFD (odds ratio [OR] 3.43, 95% confidence interval [CI] 1.75-6.72, p < 0.001) and low preoperative gait speed (OR 2.47, 95% CI 1.18-5.17, p = 0.016) as independent predictors of poor prognosis. Patients with HAFD had significantly worse total KCL scores and subscale scores for instrumental activities of daily living, mobility, oral function, and depression at 1-year post-hospital discharge. HAFD is a powerful predictor of prognosis in older patients who have undergone cardiac surgery.

Remote Cardiac Rehabilitation in Older Cardiac Disease: A Randomized Case Series Feasibility Study.

BACKGROUND: Cardiac rehabilitation (CR) in the long term is fundamental to achieve better outcomes. However, most patients may find it difficult to maintain healthy lifestyle behavior after ambulatory CR program. We aimed to investigate the feasibility on remote CR support program (Remote-CR) in older patients with cardiac disease. METHODS: Between October 2020 and February 2021, we enrolled older patients with cardiac disease after at least over 5 months of ambulatory CR program. The study was conducted as a randomized controlled case series to compare Remote-CR vs. center-based CR (CB-CR) after ambulatory CR in older patients with cardiac disease. The core component of Remote-CR is a web application, which evaluates vital sign and receives feedback through real-time video consultation once a week. We evaluated the satisfaction of Remote-CR, and impact of Remote-CR on adherence to exercise and physical activity management. Moreover, we assessed the change in functional status using handgrip strength, usual gait speed, short physical performance battery (SPPB), and Kihon checklist (KCL) before the intervention, at the end of the 4-week intervention, and cardiovascular-related hospital discharge within 6 months after completion of ambulatory CR. RESULTS: Eleven patients were enrolled (six for Remote-CR and five for CB-CR). All participants completed the intervention without serious adverse event in each group. After the on-site initial remote system set up, all the patients completed the Remote-CR session without on-site assistance. Patients' satisfaction with Remote-CR was generally high. Remote-CR helps to maintain healthy lifestyle behavior. In addition, Remote-CR and CB-CR seem to be equally successful in maintaining functional status and preventing cardiovascular-related hospital readmission. CONCLUSIONS: This trial suggested the Remote-CR comprising a hybrid of information and communication technology and strategy for health behavior change may be a feasible and safe intervention option in selected older patients with cardiac disease after completion of ambulatory CR.

Multidomain Frailty as a Therapeutic Target in Elderly Patients with Heart Failure.

Heart failure and frailty share aging as a strong risk factor. The prevalence of frailty has been shown to be particularly high in elderly patients with heart failure. Moreover, it is important not to confine frailty to physical aspects. Rather, it should be considered to consist of multiple domains, including physical disability, psychiatric disorders, cognitive impairment, depression, and social disconnection. Development of interventions that can improve frailty domains are not well established, although observational studies have evaluated the association of various frailty domains and their prognostic impact. Some interventions, including resistance exercise, functional exercise, and respiratory muscle training have been demonstrated to hold potential for improving physical frailty. In terms of cognitive dysfunction, previous studies have demonstrated that exercise therapy is also effective for cognitive dysfunction. The social domain of frailty is one of the least investigated domains, particularly in patients with heart failure. However, heart failure is also strongly associated with physical frailty and cognitive impairment and has a poor prognosis in old patients. The prevalence of social frailty in elderly patients who need hospitalization due to heart failure is higher than previously thought. Very few studies have tested interventions targeting social frailty. Frailty and heart failure affect each other, and both are becoming increasingly important in society. In this article, we review the physical, cognitive, and social domains of frailty and the possible interventions to improve them in patients with heart failure.
