Early and long-term outcomes of heart failure in elderly persons, 2001-2005.

ABSTRACT:

Background

The treatment of chronic heart failure has improved during the past 2 decades, but little is known about whether the improvements are reflected in trends in early and long-term mortality and hospital readmission.

Methods

In a retrospective cohort study of 2 540 838 elderly Medicare beneficiaries hospitalized with heart failure between January 1, 2001, and December 31, 2005, we examined early and long-term all-cause mortality and hospital readmission and patient- and hospital-level predictors of these outcomes.

Results

Unadjusted in-hospital mortality declined from 5.1% to 4.2% during the study (P < .001), but 30-day, 180-day, and 1-year all-cause mortality remained fairly constant at 11%, 26%, and 37%, respectively. Nearly 1 in 4 patients were readmitted within 30 days of the index hospitalization, and two-thirds were readmitted within 1 year. Controlling for patient- and hospital-level covariates, the hazard of all-cause mortality at 1 year was slightly lower in 2005 than in 2001 (hazard ratio, 0.98; 95% confidence interval, 0.97-0.99). The hazard of readmission did not decline significantly from 2001 to 2005 (hazard ratio, 0.99; 95% confidence interval, 0.98-1.00).

Conclusions

Early and long-term all-cause mortality and hospital readmission rates remain high and have improved little with time. The need to identify optimal management strategies for these clinically complex patients is urgent.

Project description:ImportanceApproximately 23 700 US children undergo invasive mechanical ventilation for acute respiratory failure annually, with unknown long-term effects on neurocognitive function.ObjectiveTo evaluate neurocognitive outcomes of children who survive pediatric intensive care unit (PICU) hospitalization for acute respiratory failure compared with their biological siblings.Design, setting, and participantsProspective sibling-matched cohort study conducted at 31 US PICUs and associated neuropsychology testing centers. Patients were 8 years or younger with a Pediatric Cerebral Performance Category score of 1 (normal) before PICU admission and less than or equal to 3 (no worse than moderate neurocognitive dysfunction) at PICU discharge, excluding patients with a history of neurocognitive deficits or who were readmitted and underwent mechanical ventilation. Biological siblings were aged 4 to 16 years at testing, with Pediatric Cerebral Performance Category score of 1 and no history of mechanical ventilation or general anesthesia. A total of 121 sibling pairs were enrolled from September 2, 2014, to December 13, 2017, and underwent neurocognitive testing starting March 14, 2015. The date of the final follow-up was November 6, 2018.ExposuresCritical illness and PICU treatment for acute respiratory failure.Main outcomes and measuresThe primary outcome was IQ, estimated by the age-appropriate Vocabulary and Block Design subtests of the Wechsler Intelligence Scale. Secondary outcomes included measures of attention, processing speed, learning and memory, visuospatial skills, motor skills, language, and executive function. Evaluations occurred 3 to 8 years after hospital discharge.ResultsPatients (n = 121; 55 [45%] female patients) underwent PICU care at a median (IQR) age of 1.0 (0.2-3.2) years, received a median (IQR) of 5.5 (3.1-7.7) days of invasive mechanical ventilation, and were tested at a median (IQR) age of 6.6 (5.4-9.1) years. Matched siblings (n = 121; 72 [60%] female siblings) were tested at a median (IQR) age of 8.4 (7.0-10.2) years. Patients had a lower mean estimated IQ than matched siblings (101.5 vs 104.3; mean difference, -2.8 [95% CI, -5.4 to -0.2]). Among secondary outcomes, patients had significantly lower scores than matched siblings on nonverbal memory (mean difference, -0.9 [95% CI, -1.6 to -0.3]), visuospatial skills (mean difference, -0.9 [95% CI, -1.8 to -0.1]), and fine motor control (mean difference, -3.1 [95% CI, -4.9 to -1.4]) and significantly higher scores on processing speed (mean difference, 4.4 [95% CI, 0.2-8.5]). There were no significant differences in the remaining secondary outcomes, including attention, verbal memory, expressive language, and executive function.Conclusions and relevanceAmong children, survival of PICU hospitalization for respiratory failure and discharge without severe cognitive dysfunction was associated with significantly lower subsequent IQ scores compared with matched siblings. However, the magnitude of the difference was small and of uncertain clinical importance.
