RATIONALE: This study aimed to explore whether a computer-based training in eating and nutrition for hospital nursing staff can influence the precision in nutritional treatment and care.

METHOD: A pre-intervention and post-intervention study was conducted with a cross-sectional design at each time point. The settings were one intervention (IH) and two control hospitals (CH1 and CH2). Hospital inpatients >18 years old at baseline (2012; n = 409) and follow-up (2014; n = 456) were included. The computer-based training was implemented during a period of 3 months in the IH with 297 (84%) participating registered nurses and nurse assistants. Nutritional risk was screened for using the Minimal Eating Observation and Nutrition Form. Nutritional treatment and care was recorded using a standardized protocol RESULTS: In the IH, there was an increase in the share of patients at UN risk that received energy-dense food (+16.7%) and dietician consultations (+17.3%) between baseline and follow-up, while fewer received feeding assistance (-16.2%). There was an increase in the share of patients at UN risk that received energy-dense food (+19.5%), a decrease in oral nutritional supplements (-30.5%) and food-registrations (-30.6%) in CH1, whereas there were no changes in CH2. 'Overtreatment' (providing nutritional treatment to those not at UN risk) was significantly higher in CH2 (52.7%) than in CH1 (14.3%) and in the IH (25.2%) at follow-up.

CONCLUSION: The computer-based training seemed to increase the probability for patients at UN risk in the IH to receive nutritional treatment without increasing overtreatment.
