Why the study?

The study investigated the correlation between preoperative Short Physical Performance Battery (SPPB) scores and 30-day postoperative pulmonary complications in elderly patients undergoing elective major abdominal surgery.

Does a high preoperative SPPB score predict a lower risk of 30-day postoperative pulmonary complications in elderly patients undergoing elective major abdominal surgery?

Population

645 patients aged 65 years and above scheduled for major abdominal surgery

Comparison

High SPPB score (scores of 10 or above) vs low SPPB score (scores below 10)

Design

Cohort study

Follow-up

30 days post-surgery

Key result

A preoperative SPPB score of 10 or higher was independently associated with a 37% lower risk of 30-day postoperative pulmonary complications (OR 0.63) compared to lower scores.

Structured PICO

Does a high preoperative SPPB score predict a lower risk of 30-day postoperative pulmonary complications in elderly patients undergoing elective major abdominal surgery?

P
Population
645 elderly patients (aged 65 years and older) undergoing elective major abdominal surgery, assessed for frailty using SPPB and followed for 30 days.
E
Exposure
High preoperative Short Physical Performance Battery (SPPB) score (≥ 10)
C
Comparator
Low preoperative Short Physical Performance Battery (SPPB) score (< 10)
O
Outcome
Incidence of 30-day postoperative pulmonary complications (PPCs)hard clinical

Main Result

Odds Ratio: 0.63 (95% CI 0.42–0.94)

Absolute Event Rate: 21.6% vs 32.7%

Absolute Risk Reduction: 11.1%

Number Needed to Treat: 9

p-value: p=0.025

Elevated preoperative SPPB scores (≥10) are independently associated with a decreased risk of 30-day postoperative pulmonary complications in elderly patients undergoing major abdominal surgery.

Limitations

  • Limited to elderly patients (aged 65 years and older) undergoing major elective abdominal surgery
  • SPPB is susceptible to a ceiling effect
  • Discriminative capability of SPPB remains moderate
  • Single-center observational design restricts causal inference
  • Exclusion of 23 patients due to missing preoperative SPPB data and lack of detailed preoperative pulmonary function tests may introduce selection bias
  • Limited to elderly patients undergoing major elective abdominal surgery, restricting generalizability
  • Moderate discriminative capability of the SPPB
  • Exclusion of patients due to missing data and lack of detailed preoperative pulmonary function tests may introduce selection bias

Cite This Study

Zhang et al. (2025) conducted a cohort in Elective major abdominal surgery (n=645). High preoperative SPPB score (≥ 10) vs. Low preoperative SPPB score (< 10) was evaluated on 30-day postoperative pulmonary complications (PPCs) (OR 0.63, 95% CI 0.42-0.94, p=0.025). A preoperative SPPB score of 10 or higher was independently associated with a 37% lower risk of 30-day postoperative pulmonary complications (OR 0.63) compared to lower scores.
