Effects of patient participation -based dietary intervention on nutritional status for patients with severe burns

Objective To explore the influence of patient participation-based dietary intervention on nutritional status for patients with severe burn. Methods From September 2017 to January 2019, 60 severe burn patients hospitalized in the department of burn and plastic surgery of Qingdao Municipal Hospital were recruited and divided into the experimental group (n=30) and the control group (n=30) according to the random number table method. The control group received a regular diet. While the experimental group received a patient participation-based dietary intervention(PPDI), The wound healing time and the value of nutritional status index, such as height, body mass index(BMI), serum albumin, serum prealbumin, in the two groups on admission, at 2 weeks after intervention, 4 weeks after intervention were compared. The nutritional knowledge questionnaire of burn patients and "3-day diet diary" were used for investigation. Results The score of nutritional knowledge showed no significant difference between the two groups before intervention. After intervention, the score of nutritional knowledge in the experimental group was 21.40±2.42, significantly higher than that in the control group (19.00±2.26) (t value was 3.975, P<0.01). For time effect and between-group effect, there were significant difference in serum albumin between two groups (F values were 9.232, 4.651, P<0.05); the time effect and between-group effect of serum prealbumin were statistically significant (F values were 11.592, 6.228, P < 0.05). The wound healing time in the experimental group was significantly lower than that in the control group (t value was -3.801, P<0.01). Conclusions Patient participation-based dietary intervention can effectively enhanced the level of nutritional knowledge, improved nutritional status, shortened wound healing time among patients with severe burn.
