Experts say a basic health necessity — proper nutrition — is being largely overlooked in Canadian hospitals, with patients and the health care system paying the high price.
A study in the Jan. 26 issue of Journal of Parenteral & Enteral Nutrition found that 45% of Canadian adults are malnourished upon admission to hospitals.
“Many of these patients never got better. They were just discharged early and still malnourished,” says Bridget Davidson, executive director of the Canadian Malnutrition Task Force (CMTF), a group of interested clinicians, investigators and advocates. The study, which was authored by CMTF members, monitored 1015 patients during a three-year period. The results indicated that malnourished patients were nearly twice as likely to be readmitted within 30 days “costing the system a lot of money.”
But a greater cost still, says Davidson, is the effect of malnutrition on mortality and morbidity. Malnourished patients are 6.4 times more likely to die than well-nourished patients, according to the same study. Malnutrition was also associated with a three times greater risk of complications.
The United Kingdom’s National Institute for Health and Care Excellence found that screening for malnutrition was third in terms of cost-effectiveness among health care interventions, exceeded only by treating hypertension and using birth control pills, says Dr. Leah Gramlich, provincial medical advisor for Nutrition Services in Alberta Health Services. “It’s a low-cost investment, with high return.”
“Hospital malnutrition is an unacknowledged, public health crisis,” she adds.
A survey of the 428 Canadian physicians working in 18 hospitals showed that most think nutrition assessment of patients is important, but it is not performed on a regular basis.
Davidson says medical school and nursing curricula do not spend enough time on nutrition, let alone malnutrition.
And those who are well educated are not being used efficiently, adds Gramlich. “Dietitians see well-nourished patients two-thirds of the time. Key nutrition people aren’t spending the time with the sickest people.”
One of the underlying problems in Canadian hospitals is that there are no standard methodologies to go about identifying and treating malnutrition. Counries such as the Netherlands and Britain “are far more advanced than us,” says Davidson.
With screening and detection, Gramlich says staff can target malnourished patients in hospital and encourage them to eat. The Jan. 26 study showed that a third of patients in hospital ate less than 50% of the food provided to them.
Based on surveys, patients are, for the most part, satisfied with how their food tasted, said Davidson. It seemed that access to food, such as opening packages and being properly positioned to eat, was the biggest barrier.
“Let’s set the patients up, protect their meal times. Let’s get them to eat, so if they come in malnourished, they leave nourished.”
