Patient- and hospital-level adherence to Thoracic Surgery Outcomes Research Network quality measures

		Patient-level		Hospital-level
Measure No.	Measure	Measure-adherent	Patients eligible	Measure-adherent	Hospitals eligible
1	If a patient has known/suspected non–small cell lung cancer, clinical American Joint Committee on Cancer stage should be documented before initiation of treatment	219,181 (93.0)	235,642	1164 (87.9)	1324
2	If a patient undergoes lobectomy or larger resection, pre- or intraoperative tissue diagnosis should be confirmed or reasons for not achieving documented	119,757 (99.0)	120,937	1292 (98.7)	1309
3	If a resection is performed, there should be an attempt at lymph node sampling	140,852 (90.5)	155,565	996 (76.0)	1311
4	If a patient undergoes resection for stage T1b or greater tumor, an anatomic pulmonary resection should be performed	68,573 (88.6)	77,387	906 (69.4)	1305
5	If surgical resection is performed, an R0 resection should be achieved	148,085 (96.2)	153,976	1259 (96.1)	1310
6	If a patient has pathologic stage II or higher, chemotherapy should be recommended or reason for no recommendation documented	26,898 (69.3)	38,790	297 (23.2)	1279
7	If a patient receives radiation therapy to the lung (excluding adjuvant radiation), then pathologic diagnosis should be confirmed or attempted before treatment	41,031 (83.1)	49,373	808 (64.4)	1255

Values are presented as n (%) or n. Number of patients eligible reflects the number of patients in any hospital nationally who met inclusion criteria for that specific measure. A hospital was eligible for the hospital-level analysis if at least 1 patient treated at that hospital met inclusion criteria for a specific measure. Total cohort: N = 253,182 patients and N = 1324 hospitals. American Joint Committee on Cancer seventh edition staging was used (T1b = tumors 2-3 cm).¹³
