The aim of our study reported here was to examine how nutritional status and dietary intake impact the postoperative ADL of patients presenting with hip fractures.
The sample included 51 patients more than 75 years old who had been hospitalized with hip fractures. Measurements included age, sex, length of hospitalization, presence of dementia, functional independence measure (FIM) at admission and 2 weeks postoperatively, hand grip strength, vitality index (VI), calf circumference, MNA-SF, body mass index (BMI), dietary intake preoperatively and 2 weeks postoperatively, albumin and hemoglobin levels, C-reactive protein levels, and destination at discharge. Statistical analysis involved calculating Spearman’s correlation coefficient or Pearson’s product–moment correlation coefficient for each item. Meanwhile, multiple regression analysis was performed stepwise with FIM scores from 2 weeks postoperatively as the dependent variable and other factors as independent variables. The study was approved by the Ethics Committee of Minamitama Hospital.
Correlation analysis revealed that MNA-SF score, BMI, albumin level, hand grip strength, and VI were significantly correlated with FIM scores at admission and 2 weeks postoperatively. By contrast, preoperative and postoperative dietary intake showed no association with FIM scores. The results of multiple regression analysis indicated that hand grip strength, VI, and MNA-SF score were significant variables.
Corroborating past findings, the study’s results suggest that MNA-SF scores influence FIM in the early postoperative period more than albumin or BMI. That result highlights the MNA-SF’s utility as a preoperative evaluation index. Although dietary intake typically takes more than 3 weeks to improve muscle mass with diet and exercise therapy, it appears to have minimal impact on early improvement in postoperative ADL. Patients with low preoperative dietary intake are likely to have poor postoperative intake, which warrants further investigation into dietary intake’s long-term effects on FIM at discharge.
Understanding factors that affect early improvement in postoperative ADL in acute care can help to shorten hospital stays and lead to more favorable destinations at discharge.
