Objective To explore the impact of nutritional support decision-making program based on Internet big data on perioperative patients with colorectal cancer.

Methods A total of 120 patients with colorectal cancer were selected as the research subjects.The patients were divided into the control group(n=60) and observation group(n=60) according to the random number table method.The control group received routine care, while the observation group was implemented using a nutritional support decision-making program based on Internet big data on the basis of the control group.On the day of admission and one week after intervention, the nutritional knowledge, attitude and practice, decision readiness and decision regret between two groups were compared.On the day of admission and one month after intervention, the serological nutritional indicators between two groups were compared.

Results On the day of admission, there was no statistical significance in the knowledge, attitude and practice of nutritional support, decision readiness, decision regret and serological nutritional indicators between two groups(P>0.05).One week after the intervention, the score of nutrition knowledge, attitude and practice in the observation group was higher than that in control group, the score of decision readiness was higher than that in control group, and the score of decision regret was lower than that in control group(P < 0.05 to P < 0.01).One month after the intervention, the levels of serum hemoglobin, prealbumin and albumin in the observation group were higher than those in control group(P < 0.05 to P < 0.01).

Conclusions The nutritional support decision-making program based on Internet big data is conducive to improving patients′ knowledge, attitude and practice of nutrition and their readiness for nutritional support decision-making, reducing patients′ remorse for decision-making, and improving patients′ nutritional levels.
