Observations on the prevalence of protein-calorie undernutrition in VA nursing homes

To determine the prevalence of underweight and hypoalbuminemia in Veterans Affairs nursing home residents and the frequency with which physicians, nurses, and dietitians documented their awareness of the presence of underweight and hypoalbuminemia.

Retrospective survey of medical records.

Twenty-six Department of Veterans Affairs nursing homes located in the Department's Central Region.

2811 residents.

(1) Prevalence of underweight (defined as body weight less than 80% of standard) and hypoalbuminemia (defined as serum albumin less than 3.5 g/dl); (2) frequency with which physicians, nurses, and dietitians documented the prevalence of underweight and hypoalbuminemia in the records.

Three hundred thirty-two (11.8%) of the patients were underweight and 772 (27.5%) were hypoalbuminemic. The prevalence of the two conditions varied widely across nursing homes. The prevalence of low serum albumin ranged from 5% to 58% in the 26 institutions, and the prevalence of body weight less than 80% of standard ranged from 2% to 20%. In the Region as a whole, the dietician's notes in the medical charts mentioned underweight in an average of 95% of affected cases but mentioned the suboptimal albumin level in only 82% of the hypoalbuminemic individuals. In the nurses's notes, these figures were only 80% and 45%, respectively, and in the physician's notes, only 62% and 46%, respectively. The frequency of documented awareness of underweight and hypoalbuminemia by nurses and physicians varied tremendously across the 26 facilities (as few as 7% of the undernourished cases in one nursing home, 100% of the affected individuals in another).

This study showed a high prevalence of calorie and protein undernutrition in the nursing home residents of VA nursing homes, wide variation in the prevalence across nursing homes, and frequent lack of documentation of these nutritional deficiencies by physicians and nurses.
