Health services in older psoriasis patients before and after nursing home admission. A retrospective analysis of health insurance data

BACKGROUND AND OBJECTIVE: Demographic change confers significance to healthcare management of chronic diseases like psoriasis. There are few studies on the care of older people with psoriasis, particularly for the nursing home setting. It was investigated whether the number of psoriasis patients with specialist contact changes before vs. after nursing home admission.

MATERIAL AND METHODS: We analyzed claims data of a German health insurance company including a cohort of newly admitted nursing home residents aged 65 years and older between 2011 and 2014, who received a diagnosis of psoriasis 1 year before nursing home admission. Outpatient care was compared between the years before vs. after nursing home admission. We conducted a multivariate regression analysis for identifying predictors for dermatological care.

RESULTS: The study cohort included 718 insured persons (Ø83 years). Proportion of patients who had contact to a dermatologist significantly decreased after nursing home entry (44.6% before vs. 40.1% after nursing home entry). Strongest predictors for dermatological care after entry were a previously existing dermatological contact (odds ratio, OR 3.87, 95% confidence interval, CI 2.70-5.54) and prescription for topical steroids (OR 1.61, 95% CI 1.14-2.28).

CONCLUSION: The analysis of health insurance data showed a pertinent decrease in the use of outpatient dermatological care after institutionalization. The evaluation of the adequacy of care is difficult due to the used database without clinical information. As long as no further investigations of this vulnerable patient group are available, the care of psoriasis patients of old age should be closely monitored. Dermatological knowledge of the skin in old age is an essential prerequisite for this.
