Dietitians working in primary health care are cost effective

 

Based on a review of the literature of trials conducted between 2000-2014, “Dietitians working in primary health care can also have significant economic benefits, potentially saving the health care system $5.50–$99 for every $1 spent on dietetic intervention.” (based on New Zealand dollars).1

There is no hard and fast rule when it comes to a recommended ratio of full time dietitians per patient population – it has been reported that 20-25% of all visits to a family doctor are for nutrition-related conditions such as diabetes.2
 

Dietitians deliver cost-effective nutrition interventions 

  • Nutrition counselling improves general eating behaviours associated with good health such as increased fruit, vegetable, and fibre intake and decreased fat intake3
  • Dietitians can reduce malnutrition in seniors leading to fewer hospitalizations, shorter stays and fewer readmissions4
  • Lifestyle interventions (nutrition counselling, physical activity and behaviour modification)5 can:
    • reduce the risk of developing type 2 diabetes by up to 70% in adults at risk
    • improve blood pressure and cholesterol levels (after at least 3 months)
    • decrease body weight by about 3-6 kg (after at least 12 months)
    • be associated with reversal of metabolic syndrome and has the potential to improve clinical outcomes, such as the risk of acute myocardial events6.
