Caregiver status: a simple marker to identify cardiac surgery patients at risk for longer postoperative length of stay, rehospitalization, or death.

BACKGROUND: Patients who have undergone cardiac surgery, especially those with greater comorbidities, may be cared for by family members or paid aides. OBJECTIVE: The purpose of this study was to evaluate the association between having a caregiver among patients who underwent cardiac surgery and clinical outcomes at 1 year. We hypothesized that patients with a caregiver would have longer lengths of stay and higher rehospitalization or death rates 1 year after surgery. METHODS: We studied 665 patients consecutively admitted for cardiac surgery as part of the Family Cardiac Caregiver Investigation To Evaluate Outcomes sponsored by the National Heart, Lung, and Blood Institute. The participants (mean age, 65 years; women, 35%; racial/ethnic minorities, 21%) completed an interviewer-assisted questionnaire to determine caregiver status. Outcomes were documented by a hospital-based information system; demographics/comorbidities, by electronic records. Associations between having a caregiver and outcomes were evaluated by logistic regression, adjusted for demographic and comorbid conditions. RESULTS: At baseline, 28% of the patients (n = 183) had a caregiver (8%, paid; 20%, informal only). Having a caregiver was associated with longer (>7 days) postoperative length of stay in univariate analysis among the patients with paid (odds ratio [OR], 3.00; 95% confidence interval [CI], 1.57-5.74) or informal (OR, 1.55; 95% CI, 1.04-2.31) caregivers versus none; the association remained significant for the patients with paid (OR, 2.13; 95% CI, 1.00-4.55) but not with informal (OR, 1.12; 95% CI, 0.70-1.80) caregivers after adjustment. Having a paid caregiver was significantly associated with rehospitalization/death at 1 year in univariate analysis (OR, 2.09; 95% CI, 1.18-3.69); having an informal caregiver was not (OR, 1.39; 95% CI, 0.94-2.06). Increased odds of rehospitalization/death associated with having a paid caregiver attenuated after adjustment (OR, 1.39; 95% CI, 0.74-2.62). CONCLUSIONS: The patients who underwent cardiac surgery who had a paid caregiver had a significantly longer length of stay independent of comorbidity. The increased risk of rehospitalization/death associated with having a paid caregiver was explained by demographics and comorbidity. These data suggest that caregiver status assessment may be a simple method to identify cardiac surgery patients at increased risk for adverse clinical outcomes.

Patterns of caregiving among patients hospitalized with cardiovascular disease.

BACKGROUND AND OBJECTIVES: Cardiac caregivers may represent a novel low-cost strategy to improve patient adherence to medical follow-up and guidelines and, ultimately, patient outcomes. Prior work on caregiving has been conducted primarily in mental health and cancer research; few data have systematically evaluated caregivers of cardiac patients. The purpose of this study was to evaluate the patterns of caregiving and characteristics of caregivers among hospitalized patients with cardiovascular disease (CVD) to assess disparities in caregiver burden and to determine the potential for caregivers to impact clinical outcomes. SUBJECTS AND METHODS: Consecutive patients admitted to the cardiovascular service line at a university medical center during an 11-month period were included in the Family Cardiac Caregiver Investigation To Evaluate Outcomes (FIT-O) study. Patients (n=4500; 59% white, 62% male, 93% participation rate) completed a standardized interviewer-assisted questionnaire in English or Spanish regarding assistance with medical care, daily activities, and medications in the past year and plans for posthospitalization. In univariate and multiple variable analyses, caregivers were categorized as either paid/professional (eg, nurse/home aide) or nonpaid (eg, family member/friend). RESULTS AND CONCLUSIONS: Among CVD patients, 13% planned to have a paid caregiver and 51% a nonpaid caregiver at discharge. Planned paid caregiving was more prevalent among racial/ethnic minority versus white patients (odds ratio, 1.5; 95% confidence interval, 1.2-1.8); planned nonpaid caregiving prevalence did not differ by race/ethnicity. Most nonpaid caregivers were female (78%). Patients who had nonpaid caregivers in the year prior to hospitalization (28%) reported grocery shopping/meal preparation (32%), transport to/arranging doctor visits (30%), and medication adherence/medical needs (25%) as top tasks caregivers assisted with. Following hospitalization, a majority of patients expect nonpaid caregivers, primarily women, to assist with tasks that have the potential to improve CVD outcomes such as medical follow-up, medication adherence, and nutrition, suggesting that these are important targets for caregiver education.
