Diagnosis and treatment of (disease-related) in-hospital malnutrition: the performance of medical and nursing staff

Abstract

Background & aims: Malnutrition continues to be an important problem in health care which is still under recognized and underrated in developed countries. This study aims to describe current practice in diagnosing and treating malnutrition by medical doctors, medical students and nurses prior, during and after hospitalisation.

Methods: Prospective analysis of current practice in assessing nutritional status and prescribing treatment by medical and nursing staff in a cohort of hospitalised patients from the general medical wards of the VU University Medical Center, Amsterdam. Comparison of objective identification of malnutrition by an independent observer with subjective identification by the medical and nursing staff. Quantification of diagnosing, treating and communicating malnutrition before, during and following hospital stay by medical doctors, medical students and nurses by evaluating the written information in medical and nursing charts, and referral and discharge letters.

Results: Three hundred and ninety-five women and men, aged 19-96 years, were included from June to September 2005. The prevalence of malnutrition was 31.9%. Nutritional information was not mentioned in written referrals. Medical doctors performed nutritional assessment in 15.3%, medical students in 52.8%, and nurses in 29.9% of their patients. Medical doctors were the most capable of differentiating between malnourished and well-nourished patients as a basis for undertaking nutritional assessment, although this was still inadequate. Little nutritional intervention was applied during hospital stay. Information on nutritional status was lacking in most discharge letters. Nutritional follow-up was appointed in 1.2%.

Conclusions: Nutritional assessment and intervention were not sufficiently applied by any professional at any stage of the pre-, actual and post-hospitalisation period.
