Making the case for spirometry as part of the perioperative multidisciplinary team assessment.

Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality and is significantly underdiagnosed in the community. Respiratory impairment is a key risk factor for perioperative morbidity and mortality. The National Institute for Health and Care Excellence (NICE) does not recommend routine spirometry before major surgery. However, in this article, we present the potential benefits of targeted spirometry in high-risk patient groups. Of 183 patients who underwent targeted preoperative spirometry, 25/70 (35.7%) of those with airflow obstruction had no previously known respiratory diagnosis. Of patients with known COPD, 20/46 (43.5%) were not prescribed optimum inhaled therapies for their degree of lung function deficit. Knowledge of lung function in respiratory disease helps to optimise patients perioperatively and facilitate shared decision making regarding the benefits and risk of surgeries. We propose that targeted spirometry should be used as part of the perioperative multidisciplinary team assessment of selected patients.
