Impact of a disease management program upon caregivers of chronically critically ill patients

Few studies have examined the effects of caregiving on the caregivers of chronically critically ill (CCI) patients, and no one has examined the impact of a disease management program (DMP) on physical and psychological outcomes for the caregivers of CCI patients. The purposes of this study of caregivers of CCI patients were as follows: (1) to describe the characteristics of CCI patients and caregivers and to examine the frequency of depression, subjective burden, and physical health; (2) to examine factors related to depression after hospital discharge; and (3) to examine the effects of a DMP on the physical health, depression, and burden of caregivers 2 months post-hospital discharge.

Prospective experimental design.

Caregivers of 290 patients who had received > 3 days of mechanical ventilation while in the ICU of a university medical center.

Sociodemographics, caregiver burden, physical health status, and depression were measured using established tools.

Interviews of caregivers were conducted at hospital discharge and 2 months later. Seventy-three percent of patients survived, completed the study period, and required caregiving 2 months later. Caregivers of patients residing in an institution reported higher depression (p = 0.0001), higher burden (ie, disrupted schedule, p = 0.0001; lack of family support, p = 0.036), and greater health problem scores (p = 0.0001) than did caregivers of patients residing at home. The DMP did not have a statistically significant impact on any of the outcome variables. However, by 2 months, 54% of caregivers in the experimental group had no depression or mild depression compared with 34.5% of the control group.

Two months after hospital discharge, approximately 25% of caregivers were classified as depressed with 16.7% of the depressed group classified as moderately or severely depressed. The caregivers of CCI patients are at risk for post-hospital discharge depression, and the caregivers of institutionalized CCI patients are at highest risk of long-term negative effects from caregiving.
