The identification of older nursing home residents vulnerable for deterioration of grade 1 pressure ulcers

Abstract

Aims and objective: The objective of this study was to identify prognostic factors associated with the development of pressure ulcer lesions (grade 2-4) in nursing home patients with non-blanchable erythema.

Background: No studies could be found that identify risk factors for further development of pressure ulcer in patients with non-blanchable erythema. For some patients with non-blanchable erythema, standard preventive measures do not suffice to prevent pressure ulcers from deterioration. Identifying these patients beforehand can considerably contribute to the efficiency of pressure ulcer prevention.

Design: Secondary data analyses of a previously conducted randomised controlled trial were performed.

Methods: Eighty-four wards of 16 Belgian nursing homes participated in the study. In total, 235 nursing home residents with a grade 1 pressure ulcer (non-blanchable erythema) were included. All the residents received standard preventive care. Potential prognostic factors were collected using a standardised form. The incidence of pressure ulcers was recorded according to the European pressure ulcer classification system.

Results: The cumulative pressure ulcer incidence was 18.7% (44/235). Hypotension (relative risk = 3.42, 95% CI = 1.56-7.49), a history of a cerebral vascular accident (relative risk = 1.94, 95% CI = 1.10-3.70) and contractures (relative risk = 2.02, 95% CI 1.03-3.95) were identified as independent predictive factors for developing pressure ulcers. Remarkably, being urinary incontinent decreased the risk of developing a pressure ulcer by 76%.

Conclusions: In nursing home residents with non-blanchable erythema, hypotension, contractures, and a history of cerebral vascular accident were independent risk factors for the development of pressure ulcer lesions.

Relevance to clinical practice: Patients with non-blanchable erythema who have hypotension, contractures or a history of cerebral vascular accident are in need of more intensive preventive measures. Identifying these patients can contribute considerably to a more efficient pressure ulcer prevention policy, resulting in a lower pressure ulcer lesion incidence and in lower costs.
