Abstract:
Background and objectives: Bathing services are available under long-term care insurance for the elderly. However, care workers have difficulty assessing safety for bathing in the absence of concrete criteria and guidelines. Currently, the pre-bathing health condition of care receivers is assessed mainly by blood pressure and body temperature measurements. This study aimed to identify the relationship of pre-bathing health condition assessed by blood pressure and body temperature measurements with illness and incidents related to bathing care.
Methods:
1. Design: A case-control study (prospective registry study).
2. Subjects: All registered service providers of long-term care (2,330 in total) offering at-home bathing support.
3. Methods: Cases were defined as community-dwelling residents who had a bathing care-related illness or incident. As controls, two care receivers for each service provider were randomly extracted from the collected data. The study period was 1 year, from June 2012 to May 2013. A simple comparative analysis between the two groups was conducted for age, sex, degree of independence in daily life of disabled elderly individuals (degree to which they were bedbound), degree of long-term care needed, modified Rankin Scale score, level of alertness, degree of independence in daily life of patients with dementia, blood pressure before bathing, and body temperature before bathing. Univariate and multivariate logistic regression analyses were performed, with illness and all incidents or illness and incidents excluding elevated body temperature and elevated or reduced blood pressure as objective variables, and other factors as explanatory variables. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated.
Results: A total of 596 cases and 1,511 controls were analyzed. Simple comparative analysis revealed more care receivers had elevated body temperature before bathing in the case group than in the control group. Multivariate analysis with illness and incidents excluding elevated body temperature and blood pressure changes as objective variables showed significant relationships when systolic blood pressure was 160-179 mmHg (OR, 3.63; 95%CI, 1.39-9.50), diastolic blood pressure was 100-109 mmHg (OR, 14.71; 95%CI, 1.31-165.77), body temperature was 37.5-37.9°C(OR, 16.47; 95%CI, 3.30-82.40), and body temperature was ≥38.0°C (OR, 6.57; 95%CI, 1.40-30.81) before bathing.
Conclusion: High blood pressure (≥160/100 mmHg) and elevated body temperature (≥37.5°C) before bathing are possible risk factors of bathing-care-related illness and incidents.
