Health-related quality of life and long-term morbidity and mortality in patients hospitalised with systolic heart failure.

ABSTRACT: BACKGROUND:Health-related quality of life has been shown to impact prognosis in chronic heart failure, however with limited long-term follow-up. We analysed data spanning 8-12 years to assess the impact of health-related quality of life using the Nottingham Health Profile on first hospitalisation and mortality, for cardiovascular and all causes. METHODS:We included 208 patients aged ?60 years with New York Heart Association class II-IV and left ventricular systolic dysfunction hospitalised in Stockholm during 1996-99. Data on hospital admissions, discharge diagnoses and date and cause of death were collected from administrative databases and medical records until 2007. Cox proportional hazard models were employed to analyse the time to event for mortality and hospitalisations. RESULTS:Mean age was 76 years, 58% were male and mean ejection fraction was 34%. Median survival was 4.6 years (range 6 days-11.9 years); 148 patients died. All-cause and cardiovascular mortality were determined by physical mobility (by Nottingham Health Profile), age, gender, diuretic dose and haemoglobin level. Glomerular filtration rate was significant for all-cause mortality, while atrioventricular plane displacement was predictive of cardiovascular mortality. Median time to first all-cause and cardiovascular hospitalisation was 5.7 and 11.2 months, respectively. Time to first all-cause hospitalisation was determined by physical mobility, emotional reactions, age, gender and haemoglobin level, while only physical mobility and diuretic dose predicted time to first cardiovascular hospitalisation. CONCLUSIONS:In conclusion, in patients with systolic chronic heart failure, physical mobility as part of health-related quality of life is an independent prognostic marker for cardiovascular and all-cause readmissions and mortality over 12 years.

Project description:ObjectivesA companion article reports the trajectory of long-term mortality and significant health-related quality of life disability among children encountering septic shock. In this article, the investigators examine critical illness factors associated with these adverse outcomes.DesignProspective, cohort-outcome study, conducted 2013-2017.SettingTwelve United States academic PICUs.PatientsCritically ill children, 1 month to 18 years, with community-acquired septic shock requiring vasoactive-inotropic support.InterventionsIllness severity, organ dysfunction, and resource utilization data were collected during PICU admission. Change from baseline health-related quality of life at the month 3 follow-up was assessed by parent proxy-report employing the Pediatric Quality of Life Inventory or the Stein-Jessop Functional Status Scale.Measurements and main resultsIn univariable modeling, critical illness variables associated with death and/or persistent, serious health-related quality of life deterioration were candidates for multivariable modeling using Bayesian information criterion. The most clinically relevant multivariable models were selected among models with near-optimal statistical fit. Three months following septic shock, 346 of 389 subjects (88.9%) were alive and 43 of 389 had died (11.1%); 203 of 389 (52.2%) had completed paired health-related quality of life surveys. Pediatric Risk of Mortality, cumulative Pediatric Logistic Organ Dysfunction scores, PICU and hospital durations of stay, maximum and cumulative vasoactive-inotropic scores, duration of mechanical ventilation, need for renal replacement therapy, extracorporeal life support or cardiopulmonary resuscitation, and appearance of pathologic neurologic signs were associated with adverse outcomes in univariable models. In multivariable regression analysis (odds ratio [95% CI]), summation of daily Pediatric Logistic Organ Dysfunction scores, 1.01/per point (1.01-1.02), p < 0.001; highest vasoactive-inotropic score, 1.02/per point (1.00-1.04), p = 0.003; and any acute pathologic neurologic sign/event, 5.04 (2.15-12.01), p < 0.001 were independently associated with death or persistent, serious deterioration of health-related quality of life at month 3.Conclusions and relevanceBiologically plausible factors related to sepsis-associated critical illness organ dysfunction and its treatment were associated with poor outcomes at month 3 follow-up among children encountering septic shock.

Project description:BackgroundWe aimed to develop a multivariable statistical model for risk stratification in patients with chronic heart failure with systolic dysfunction, using patient data that are routinely collected and easily obtained at the time of initial presentation.Methods and resultsIn a cohort of 2331 patients enrolled in the HF-ACTION (Heart Failure: A Controlled Trial Investigating Outcomes of Exercise TraiNing) study (New York Heart Association class II-IV, left ventricular ejection fraction ≤0.35, randomized to exercise training and usual care versus usual care alone, median follow-up of 2.5 years), we performed risk modeling using Cox proportional hazards models and analyzed the relationship between baseline clinical factors and the primary composite end point of death or all-cause hospitalization and the secondary end point of all-cause death alone. Prognostic relationships for continuous variables were examined using restricted cubic spline functions, and key predictors were identified using a backward variable selection process and bootstrapping methods. For ease of use in clinical practice, point-based risk scores were developed from the risk models. Exercise duration on the baseline cardiopulmonary exercise test was the most important predictor of both the primary end point and all-cause death. Additional important predictors for the primary end point risk model (in descending strength) were Kansas City Cardiomyopathy Questionnaire symptom stability score, higher serum urea nitrogen, and male sex (all P<0.0001). Important additional predictors for the mortality risk model were higher serum urea nitrogen, male sex, and lower body mass index (all P<0.0001).ConclusionsRisk models using simple, readily obtainable clinical characteristics can provide important prognostic information in ambulatory patients with chronic heart failure with systolic dysfunction.Clinical trial registrationURL: http://www.clinicaltrials.gov.
