Clinical Report: Nomogram for Predicting Early Pulmonary Recovery Failure

Overview

This study developed and validated a prehabilitation-enhanced nomogram to predict early postoperative pulmonary recovery failure within 7 days after lung tumor surgery.

Background

Postoperative pulmonary complications are common after lung tumor resection, leading to increased morbidity and healthcare costs. Traditional risk assessment methods often fail to capture dynamic perioperative changes.

Data Highlights

Key Findings

• The prehabilitation-enhanced nomogram included five predictors: intraoperative blood loss, DLCO% predicted, preoperative resting SpO2, incentive spirometry target-achieved days, and breathing training target-achieved days.
• Adding prehabilitation indicators improved discrimination in all cohorts, with AUCs increasing significantly.
• The nomogram outperformed any single predictor in terms of predictive capability.
• Calibration was acceptable across cohorts.
• Decision curve analysis supported the clinical usefulness of the nomogram.

Clinical Implications

The nomogram provides a tool for individualized risk stratification of early postoperative pulmonary recovery failure, which can guide targeted interventions and resource allocation. Incorporating prehabilitation indicators may enhance postoperative care strategies.

Conclusion

The development of a prehabilitation-enhanced nomogram represents a tool for predicting early postoperative pulmonary recovery failure.
