A Cross-Sectional Examination of the Association Between Dyspnea and Distress as Experienced by Palliative Home Care Clients and Their Informal Caregivers

Prevalence and Risk Factors of Breathlessness Across Canada: A National Retrospective Cohort Study in Home Care and Nursing Home Populations

CONTEXT

Breathlessness is a symptom associated with poor clinical outcomes and prognosis. Little is known about its long-term trends and associations with social factors including decline in social activities and caregiver distress.

OBJECTIVES

To describe factors associated with the prevalence of clinician-reported breathlessness across Canada among cohorts receiving home care or nursing home care.

METHODS

A retrospective observational cohort study of cross-sectional intake assessment data from Canadian interRAI Home Care and Nursing Home data sets. In each data set, we examined covariates associated with the presence of clinician-reported breathlessness using multivariate regression.

RESULTS

Between 2007 and 2018, we identified 1,317,117 and 469,709 individuals from the home care and nursing home data sets, respectively. Over two-thirds were aged >75 and over 60% were women. Breathlessness was present at intake in 26.0% of the home care and 8.2% of the nursing home cohorts. Between 2007 and 2018, prevalence of breathlessness increased by 10% for the home care cohort, while remaining relatively constant in nursing homes. Covariates associated with increased odds of having clinician-reported breathlessness at intake in both cohorts were moderate-severe impairment with activities of daily living, being male, older age, high pain scores, signs of depression, and decline in social activities. In the home care cohort, the presence of breathlessness was associated with a greater odds of caregiver distress (odds ratio = 1.19, 95% CI: 1.18-1.20).

CONCLUSION

The prevalence of clinician-reported breathlessness is higher in home care than in nursing home populations, the former having risen by 10% over the decade. Prevalence of breathlessness is associated with decline in social activities and caregiver distress. Enhanced supports may be required to meet increasing patient need in the community.

Predictors of Caregiver Distress in the Community Setting Using the Home Care Version of the Resident Assessment Instrument

PURPOSE OF STUDY

The purpose of this study was to identify factors predictive of new onset and improved caregiver distress among informal caregivers providing assistance for clients receiving home care.

PRIMARY PRACTICE SETTINGS

Home care.

METHODOLOGY AND SAMPLE

The sample included 323,409 clients receiving home care from a Community Care Access Centre between March 2002 and March 2015 for whom data were available from two subsequent Resident Assessment Instrument-Home Care (RAI-HC) assessments. Separate multivariate logistic regression models were created for onset of and improvement in caregiver distress.

RESULTS

Variables that increase the odds in onset of caregiver distress included primary caregiver is not satisfied with support received from family and friends; client lives with primary caregiver; 65 years and older; has Alzheimer and other related dementia; has condition or disease that makes cognition, activities of daily living, mood, or behavior patterns unstable; took sedatives in the last 7 days; Method for Assigning Priority Levels (MAPLe) score 4 or more; demonstrates persistent anger; has difficulty using the telephone; is married; requires 20 hr or more of informal help weekly; and Clinical Risk Scale score 4 or more. Variables that increased the odds of improved caregiver distress include client now lives with other persons (as compared with 90 days ago); demonstrates good prospects for recovery; treatment changes in last 30 days; surgical wound; female; one or more hospital visits in last 90 days; greater number of months between RAI-HC assessments; and two or more hours of physical activities in the last 3 days. Variables that decreased the odds of improved caregiver distress (i.e., persistent distress) include MAPLe score 4 or more; persistent anger; difficulty using telephone; Alzheimer, related dementia; requires interpreter; and lives with primary caregiver.

IMPLICATIONS FOR CASE MANAGEMENT PRACTICE

Informal caregivers provide essential support for home care clients. Factors predictive of new onset and improved caregiver distress can be used by case managers for comprehensive care planning that addresses the collective needs of the client-caregiver dyad.
