Nutritional risk predicts postoperative complications and length of stay, whereas sarcopenia risk predicts need for step-down care in a mixed elective surgery population.

BACKGROUND

Malnutrition and poor functional reserves place patients at risk for negative surgical outcomes. In this prospective study we aimed to measure preoperative nutritional and sarcopenia risk and evaluate their impact on postoperative outcomes.

METHODS

Adults scheduled to undergo elective general and gastrointestinal surgery were screened for nutrition risk using the Malnutrition Universal Screening Tool screening tool. Sarcopenia risk was measured using the SARC-F tool and hand-grip strength. Patients were followed postoperatively. Incidence of complications, length of stay (LOS), readmission rates, and need for step-down care were recorded.

RESULTS

One hundred and twenty-two patients were included. Mean age was 53.8 years (standard deviation [SD] 16.44). Sixty-six (54%) were scheduled for day-case procedures, and 56 (46%) for nonday-case procedures. About 18.9% (n = 23) were at nutritional risk preoperatively. Ten patients (8.2%) had probable sarcopenia based on SARC-F, whereas seven (5.7%) had measurably reduced HG. Incidence of postoperative complications was 23.8% (n = 29). Nutrition risk was associated with the development of complications (p = 0.018). In the nonday-case group, nutritional risk was associated with greater LOS (p = 0.013). Older age was associated with need for step-down care (p = 0.002) as was SARC-F (p = 0.003).

CONCLUSIONS

Preoperative nutritional screening can predict postoperative complications and LOS, whereas sarcopenia screening is predictive of the need for step-down care after discharge. Screening tools are quick and inexpensive and could provide valuable information to clinicians and allow patients the opportunity to enhance their physical preparedness for surgery thereby mitigating their risk for negative surgical outcomes.
