Survey responses regarding pulmonary assessment prior to elective lung resection.

Preoperative Pulmonary Assessment	n (%)
Order spirometry
Always	200 (98.5)
Usually	3 (1.5)
Calculate ppoFEV 1
Always	156 (77.2)
Usually	16 (7.9)
Sometimes	23 (11.4)
Rarely	5 (2.5)
Never	2 (1.0)
Order DLCO
Always	172 (84.7)
Usually	19 (9.4)
Sometimes	10 (4.9)
Rarely	2 (1.0)
Calculate ppoDLCO
Always	117 (57.6)
Usually	31 (15.3)
Sometimes	31 (15.3)
Rarely	13 (6.4)
Never	11 (5.4)
Repeat PFTs after neoadjuvant therapy
Always	57 (28.1)
Usually	30 (14.8)
Sometimes	53 (26.1)
Rarely	51 (25.1)
Never	12 (5.9)
If ppoFEV1 or ppoDLCO is __ I further evaluate the patient
< 60%	20 (9.9)
<40%	121 (59.6)
<30%	15 (7.4)
My threshold varies by surgical approach	47 (23.2)
My further evaluation consists of
Cardiopulmonary exercise testing (CPET) - VO2 max testing	116 (57.1)
Stair climbing test	36 (17.7)
Shuttle walk test	0 (0.0)
6-minute walk test	26 (12.8)
I do not order additional tests; If the FEV1 and/or DLCO are less than my threshold, I will not operate.	18 (8.9)
Other	7 (3.4)
I refer my patients with borderline pulmonary function for preoperative pulmonary rehabilitation
Always	13 (6.4)
Usually	42 (20.7)
Sometimes	69 (34.0)
Rarely	56 (27.6)
Never	23 (11.3)
I refer my patients with borderline pulmonary function for postoperative pulmonary rehabilitation
Always	43 (21.2)
Usually	52 (25.6)
Sometimes	69 (34.0)
Rarely	27 (13.3)
Never	12 (5.9)

FEV₁: forced expiratory volume in 1 second; DLCO: diffusion capacity of the lungs for carbon monoxide; ppoFEV₁: predicted postoperative forced expiratory volume in 1 second; ppoDLCO: predicted postoperative diffusion capacity of the lungs for carbon monoxide; PFTs: pulmonary function tests
