Handheld office-based spirometry versus laboratory spirometry in low-risk patients undergoing lung resection

Area of Science:

• Pulmonary Medicine
• Respiratory Diagnostics
• Surgical Pre-assessment

Background:

• Pulmonary function tests are crucial for assessing surgical risk in patients undergoing lung resection.
• Traditional laboratory spirometry is time-consuming and resource-intensive for routine pre-operative evaluations.

Purpose of the Study:

• To compare the accuracy and efficiency of handheld office spirometry against standard laboratory spirometry.
• To evaluate the utility of office spirometry in identifying high-risk patients for pulmonary resection.

Main Methods:

• A prospective study enrolled low-risk patients undergoing evaluation for lung resection.
• Patients underwent both office spirometry and laboratory spirometry, with laboratory results serving as the gold standard.
• Pre-defined criteria (FEV1 <1.5 L or FEV1% <60%) were used to classify patients as high risk.

Main Results:

• Office and laboratory spirometry yielded comparable Forced Expiratory Volume in 1 second (FEV1) and FEV1% values.
• Office spirometry demonstrated 100% sensitivity and 93% specificity in identifying high-risk patients.
• Office spirometry added only 1 minute to clinic visits, compared to 42 minutes for laboratory spirometry.

Conclusions:

• Handheld office spirometry provides clinically comparable results to laboratory spirometry for pre-operative lung resection assessment.
• Office spirometry offers a time-efficient and potentially cost-effective alternative for patient evaluation.
• This method can aid in streamlining the pre-operative workup process.
