Patient-reported outcome is associated with health care costs in patients with ischaemic heart disease and arrhythmia.

AIMS: Systematic use of patient-reported outcomes (PROs) have the potential to improve quality of care and reduce costs of health care services. We aimed to describe whether PROs in patients diagnosed with heart disease are directly associated with health care costs. METHODS AND RESULTS: A national cross-sectional survey including PROs at discharge from a heart centre with 1-year follow-up using data from national registers. We included patients with either ischaemic heart disease (IHD), arrhythmia, heart failure (HF), or valvular heart disease (VHD). The Hospital Anxiety and Depression Scale, the heart-specific quality of life, the EuroQol five-dimensional questionnaire, and the Edmonton Symptom Assessment Scale were used. The economic analysis was based on direct costs including primary, secondary health care, and medical treatment. Patient-reported outcomes were available from 13 463 eligible patients out of 25.241 [IHD (n = 7179), arrhythmia (n = 4322), HF (n = 987), or VHD (n = 975)]. Mean annual total direct costs in all patients were €23 228 (patients with IHD: €19 479, patients with arrhythmia: €21 076, patients with HF: €34 747, patients with VDH: €48 677). Hospitalizations contributed overall to the highest part of direct costs. For patients discharged with IHD or arrhythmia, symptoms of anxiety or depression, worst heart-specific quality of life or health status, and the highest symptom burden were associated with increased economic expenditure. We found no associations in patients with HF or VHD. CONCLUSION: Patient-reported outcomes at discharge from a heart centre were associated with direct health care costs in patients with IHD and arrhythmia.

Supplementing prediction by EuroSCORE with social and patient-reported measures among patients undergoing cardiac surgery.

OBJECTIVES: The risk of poor outcomes is traditionally attributed to biological and physiological processes in cardiac surgery. However, evidence exists that other factors, such as emotional, behavioral, social, and functional, are predictive of poor outcomes. Objectives were to evaluate the predictive value of several emotional, social, functional, and behavioral factors on four outcomes: death within 90 days, prolonged stay in intensive care, prolonged hospital admission, and readmission within 90 days following cardiac surgery. METHODS: This prospective study included adults undergoing cardiac surgery 2013-2014, including information on register-based socioeconomic factors and self-reported health in a nested subsample. Logistic regression analyses to determine the association and incremental value of each candidate predictor variable were conducted. Multiple regression analyses were used to determine the incremental value of each candidate predictor variable, as well as discrimination and calibration based on the area under the curve (AUC) and Brier score. RESULTS: Of 3217 patients, 3% died, 9% had prolonged intensive care stay, 51% had prolonged hospital admission, and 39% were readmitted to hospital. Patients living alone (odds ratio, 1.19; 95% confidence interval, 1.02-1.38), with lower educational levels (1.27; 1.04-1.54) and low health-related quality of life (1.43; 1.02-2.01) had prolonged hospital admission. Analyses revealed living alone as predictive of prolonged intensive care unit (ICU) stay (Brier, 0.08; AUC, 0.68), death (0.03; 0.71), and prolonged hospital admission (0.24; 0.62). CONCLUSION: Living alone was found to supplement EuroSCORE in predicting death, prolonged hospital admission, and prolonged ICU stay following cardiac surgery. Low educational level and impaired health-related quality of life were, furthermore, predictive of prolonged hospital admission.

Predictors of patient-reported outcomes at discharge in patients with heart failure.

BACKGROUND: It is well-established that heart failure has a negative impact on quality of life. However, little is known about patient-related predictors of health-related quality of life, anxiety and depression, symptoms and illness perception among patients with heart failure. AIM: To study the association between patient-related predictors and patient-reported outcome measures at discharge from hospital in a cohort of patients with heart failure. METHODS: We used data from 1506 patients with heart failure, participating in the national DenHeart Survey of patient-reported outcome measures in patients with heart disease. The potential patient-related predictors included demographic, administrative, clinical and socioeconomic factors. The patient-reported outcome measures included six questionnaires: the Short Form-12, the Hospital Anxiety and Depression Scale, the EuroQol five-dimensional, five-level questionnaire, the HeartQoL, the Brief Illness Perception Questionnaire and the Edmonton Symptom Assessment Scale. Data were linked to national patient registry data and medical records. We performed multivariable linear and logistic regression analyses. RESULTS: In adjusted linear regression analyses we found that a length of hospital stay of >2 days was associated with worse scores across questionnaires, except for the Brief Illness Perception Questionnaire. Higher comorbidity level was associated with worse scores across all questionnaires, whereas low social support was associated with worse scores across questionnaires, except for the physical domain of the Short Form-12 and the HeartQoL global score. CONCLUSIONS: This study identified length of hospital stay > 2 days, a higher comorbidity level and low social support to be associated with worse scores across questionnaires at discharge from a cardiac-related hospitalisation in patients with heart failure.

Educational inequality in patient-reported outcomes but not mortality among cardiac patients: Results from the national DenHeart survey with register follow-up.

Aims: This study aimed to explore whether educational level is associated with mental and physical health status, anxiety and depression symptoms and quality of life at hospital discharge and predicts cardiac events and all-cause mortality 1 year after hospital discharge in patients with ischaemic heart disease, arrhythmias, heart failure or heart valve disease. Methods: The DenHeart survey is cross-sectional and combined with data from national registers. Information on educational level and co-morbidity at hospital discharge and cardiac events and mortality 1-year post-discharge was obtained from registers. Patient-reported outcomes included SF-12, Hospital Anxiety and Depression Scale and HeartQoL. Multivariate linear and logistic regression and Cox proportional hazards regression models were used. Results: A total of 13,145 patients were included. A significant educational gradient was found in patient-reported mental and physical health status, anxiety and depression symptoms and quality of life, with lower educational groups reporting worse outcomes in adjusted analyses. No association was found between educational level and risk of cardiac events or all-cause mortality within 1 year after hospital discharge in adjusted analyses. Conclusions: In a large population of patients with cardiac disease a significant educational gradient was found in mental and physical health and quality of life at hospital discharge. There was, however, no association between educational level and risk of cardiac events or mortality 1 year after hospital discharge.

Cognitive behavioural therapy significantly reduces anxiety in patients with implanted cardioverter defibrillator compared with usual care: Findings from the Screen-ICD randomised controlled trial.

AIM: The aim of this study was to investigate the effect of a cognitive behavioural therapy intervention provided by trained cardiac nurses plus usual care compared with usual care alone in patients with an implanted cardioverter defibrillator who, prior to randomization, had presented with symptoms of anxiety measured by the Hospital Anxiety and Depression Scale. BACKGROUND: Around 20-25% of all patients with an implanted cardioverter defibrillator experience anxiety. Among these patients anxiety is associated with mortality, presumably explained by risk behaviour and activation of the autonomic nervous system. We hypothesised that cognitive behavioural therapy provided by cardiac nurses in an out-patient setting would be an effective treatment of anxiety. METHODS: This was an investigator-initiated randomised clinical superiority trial with blinded outcome assessment, with 1:1 randomisation to cognitive behavioural therapy plus usual care or to usual care. The primary outcome was Hospital Anxiety and Depression Scale-Anxiety mean score at 16 weeks. Secondary outcomes included Hospital Anxiety and Depression Scale-Depression, Becks Anxiety Inventory, HeartQoL and Hamilton Anxiety Scale. Primary outcome analysis was based on the intention-to-treat principle. RESULTS: A total of 88 participants were included, 66% men, mean age 64.3 years and 61% had primary indication implantable cardioverter defibrillator. A significant difference after 16 weeks was found between groups: intervention group (Hospital Anxiety and Depression Scale-A mean (standard deviation) 4.95 points (3.30) versus usual care group 8.98 points (4.03) (p < 0.0001)). Cohen's d was -0.86, indicating a strong clinical effect. The effect was supported by secondary outcomes. CONCLUSION: Cognitive behavioural therapy provided by cardiac nurses to patients with a positive screening for anxiety had a statistically and clinically significant effect on anxiety compared with patients not receiving cognitive behavioural therapy.

Patient-reported outcomes are independent predictors of one-year mortality and cardiac events across cardiac diagnoses: Findings from the national DenHeart survey.

AIMS: Patient-reported quality of life and anxiety/depression scores provide important prognostic information independently of traditional clinical data. The aims of this study were to describe: (a) mortality and cardiac events one year after hospital discharge across cardiac diagnoses; (b) patient-reported outcomes at hospital discharge as a predictor of mortality and cardiac events. DESIGN: A cross-sectional survey with register follow-up. METHODS: Participants: All patients discharged from April 2013 to April 2014 from five national heart centres in Denmark. MAIN OUTCOMES: Patient-reported outcomes: anxiety and depression (Hospital Anxiety and Depression Scale); perceived health (Short Form-12); quality of life (HeartQoL and EQ-5D); symptom burden (Edmonton Symptom Assessment Scale). Register data: mortality and cardiac events within one year following discharge. RESULTS: There were 471 deaths among the 16,689 respondents in the first year after discharge. Across diagnostic groups, patients reporting symptoms of anxiety had a two-fold greater mortality risk when adjusted for age, sex, marital status, educational level, comorbidity, smoking, body mass index and alcohol intake (hazard ratio (HR) 1.92, 95% confidence interval (CI) 1.52-2.42). Similar increased mortality risks were found for patients reporting symptoms of depression (HR 2.29, 95% CI 1.81-2.90), poor quality of life (HR 0.46, 95% CI 0.39-0.54) and severe symptom distress (HR 2.47, 95% CI 1.92-3.19). Cardiac events were predicted by poor quality of life (HR 0.71, 95% CI 0.65-0.77) and severe symptom distress (HR 1.58, 95% CI 1.35-1.85). CONCLUSIONS: Patient-reported mental and physical health outcomes are independent predictors of one-year mortality and cardiac events across cardiac diagnoses.

Sociodemographic, Clinical and Patient-Reported Outcomes and Readmission After Heart Valve Surgery.

BACKGROUND: Readmissions after heart valve surgery represent a significant burden for both the patient and the healthcare system. The study aim was to identify independent predictors of readmission within 180 days after surgery in a population of patients undergoing heart valve surgery. METHODS: Demographic and clinical information was obtained from national registers. Patient-reported outcomes (PROs) including Short Form 12 (SF-12) and EuroQol 5D (EQ-5D) were measured at discharge as part of a national, cross-sectional study (DenHeart). Predictors of first readmission were investigated. RESULTS: Among a total of 1,084 patients (65% men; mean age 68 years; 354 responded to questionnaires), 534 (49%) were readmitted. Responding patients who were readmitted were younger and a greater proportion had undergone mitral valve surgery. A significantly higher proportion of non-responders was readmitted. No significant differences were found in PROs between patients readmitted and those not readmitted, and receiver operating characteristic (ROC) curves showed no predictive effect of SF-12 and EQ-5D. Survival analysis using Cox proportional hazard models showed that prior percutaneous coronary intervention (PCI) (HR 1.50, CI 1.10; 2.05, p = 0.010) and a history of heart failure (HR 1.37, CI 1.10; 1.72, p = 0.006) were predictive of readmission. CONCLUSIONS: Readmission rates after heart valve surgery are high and often seen in patients who have undergone PCI and heart failure before surgery. Predictors for these high readmissions rates are difficult to establish based on medical history and type of surgery. PROs at discharge contribute information regarding a patient's perception of their often poor quality of life, but do not predict readmission.

Patient-reported outcomes after aortic and mitral valve surgery - results from the DenHeart Study.

BACKGROUND: Clinical course, co-morbidity and age often differs between patients undergoing aortic and mitral valve surgery and this might affect patient-reported outcomes. AIMS: The purpose of this study was to describe differences in patient-reported physical and mental health and health-related quality of life after aortic valve or mitral valve surgery, and to identify demographic and clinical characteristics associated with worse patient-reported physical and mental health, and health-related quality of life. METHODS: Patient-reported outcomes were measured at discharge as a part of a national, cross-sectional study (DenHeart). Patient-reported outcome measures included: Short-Form-12, Hospital Anxiety and Depression Scale, EuroQol-5D-5L, HeartQol and Edmonton Symptom Assessment System. Demographic and clinical information was obtained from national registers. RESULTS: Of 354 patients (65% men, mean age: 68 years), 79% underwent aortic valve surgery. Patients who had undergone aortic valve surgery had more symptoms of anxiety compared with patients who had undergone mitral valve surgery (34% vs 17%, p=0.003, Hospital Anxiety and Depression Scale anxiety cut-off score of eight). Being female was associated with worse patient-reported outcomes on all measures, whereas being unmarried was associated with worse physical health (Physical Component Score Short-Form-12) and symptom burden (Edmonton Symptom Assessment System). Length of stay was associated with worse symptoms on EuroQol-5D-5L Visual Analogue Scale. Age and comorbidity were not associated with patient-reported outcomes. CONCLUSION: Patients who had undergone aortic valve and mitral valve surgery did not significantly differ in patient-reported health at discharge, except for symptoms of anxiety. Being female was the only characteristic associated with overall worse patient-reported outcomes at discharge.

Cardiac rehabilitation versus usual care for patients treated with catheter ablation for atrial fibrillation: Results of the randomized CopenHeartRFA trial.

BACKGROUND: To assess the effects of comprehensive cardiac rehabilitation compared with usual care on physical activity and mental health for patients treated with catheter ablation for atrial fibrillation. METHODS: The patients were randomized 1:1 stratified by paroxysmal or persistent atrial fibrillation and sex to cardiac rehabilitation consisting of 12 weeks physical exercise and four psycho-educational consultations plus usual care (cardiac rehabilitation group) versus usual care. The primary outcome was Vo2 peak. The secondary outcome was self-rated mental health measured by the Short Form-36 questionnaire. Exploratory outcomes were collected. RESULTS: 210 patients were included (mean age: 59 years, 74% men), 72% had paroxysmal atrial fibrillation prior to ablation. Compared with usual care, the cardiac rehabilitation group had a beneficial effect on Vo2 peak at four months (24.3mL kg-1 min-1 versus 20.7mL kg-1 min-1, p of main effect=0.003, p of interaction between time and intervention=0.020). No significant difference between groups on Short Form-36 was found (53.8 versus 51.9 points, P=.20). Two serious adverse events (atrial fibrillation in relation to physical exercise and death unrelated to rehabilitation) occurred in the cardiac rehabilitation group versus one in the usual care group (death unrelated to intervention) (P=.56). In the cardiac rehabilitation group 16 patients versus 7 in the usual care group reported non-serious adverse events (P=.047). CONCLUSION: Comprehensive cardiac rehabilitation had a positive effect on physical capacity compared with usual care, but not on mental health. Cardiac rehabilitation caused more non-serious adverse events.

Cardiac rehabilitation increases physical capacity but not mental health after heart valve surgery: a randomised clinical trial.

OBJECTIVE: The evidence for cardiac rehabilitation after valve surgery remains sparse. Current recommendations are therefore based on patients with ischaemic heart disease. The aim of this randomised clinical trial was to assess the effects of cardiac rehabilitation versus usual care after heart valve surgery. METHODS: The trial was an investigator-initiated, randomised superiority trial (The CopenHeartVR trial, VR; valve replacement or repair). We randomised 147 patients after heart valve surgery 1:1 to 12 weeks of cardiac rehabilitation consisting of physical exercise and monthly psycho-educational consultations (intervention) versus usual care without structured physical exercise or psycho-educational consultations (control). Primary outcome was physical capacity measured by VO2 peak and secondary outcome was self-reported mental health measured by Short Form-36. RESULTS: 76% were men, mean age 62 years, with aortic (62%), mitral (36%) or tricuspid/pulmonary valve surgery (2%). Cardiac rehabilitation compared with control had a beneficial effect on VO2 peak at 4 months (24.8 mL/kg/min vs 22.5 mL/kg/min, p=0.045) but did not affect Short Form-36 Mental Component Scale at 6 months (53.7 vs 55.2 points, p=0.40) or the exploratory physical and mental outcomes. Cardiac rehabilitation increased the occurrence of self-reported non-serious adverse events (11/72 vs 3/75, p=0.02). CONCLUSIONS: Cardiac rehabilitation after heart valve surgery significantly improves VO2 peak at 4 months but has no effect on mental health and other measures of exercise capacity and self-reported outcomes. Further research is needed to justify cardiac rehabilitation in this patient group. TRIAL REGISTRATION NUMBER: NCT01558765, Results.
