Survival Before and After Direct Surgical Quality Feedback in a Population-Based Lung Cancer Cohort.

BACKGROUND: Surgical resection is the main curative modality for non-small cell lung cancer (NSCLC), but variation in the quality of care contributes to suboptimal survival rates. Improving surgical outcomes by eliminating quality deficits is a key strategy for improving population-level lung cancer survival. We evaluated the long-term survival effect of providing direct feedback on institutional performance in a population-based cohort. METHODS: The Mid-South Quality of Surgical Resection cohort includes all NSCLC resections at 11 hospitals in four contiguous Dartmouth Hospital Referral Regions in Arkansas, Mississippi, and Tennessee. We evaluated resections from 2004 to 2013, before and after onset of a benchmarked performance feedback campaign to surgery and pathology teams in 2009. RESULTS: We evaluated 2,206 patients: 56% preintervention (pre-era) and 44% postintervention (post-era). Preoperative positron emission tomography/computed tomography (46% vs 82%, p < 0.0001), brain scans (6% vs 21%, p < 0.0001), and bronchoscopy (8% vs 27%, p < 0.0001) were more frequently used in the post-era. Patients had 5-year survival of 47% (44% to 50%) in the pre-era compared with 53% (50% to 56%) in the post-era (p = 0.0028). The post-era had an adjusted hazard ratio of 0.85 (95% confidence interval [CI], 0.75 to 0.97; p = 0.0158) compared with the pre-era. This differed by extent of resection (p = 0.0113): compared with the pre-era, the post-era adjusted hazard ratio was 0.49 (95% CI, 0.33 to 0.72) in pneumonectomy, 0.91 (95% CI, 0.79 to 1.05) in lobectomy/bilobectomy, and 0.85 (95% CI, 0.63 to 1.15) in segmentectomy/wedge resections. CONCLUSIONS: Overall survival after surgical resection improved significantly in a high lung cancer mortality region of the United States. Reasons may include better selection of patients for pneumonectomy and more thorough staging.

Evolution in the Surgical Care of Patients With Non-Small Cell Lung Cancer in the Mid-South Quality of Surgical Resection Cohort.

Surgery is the most important curative treatment modality for patients with early-stage non-small cell lung cancer (NSCLC). We examined the pattern of surgical resection for NSCLC in a high incidence and mortality region of the United States over a 10-year period (2004-2013) in the context of a regional surgical quality improvement initiative. We abstracted patient-level data on all resections at 11 hospitals in 4 contiguous Dartmouth Hospital Referral Regions in North Mississippi, East Arkansas, and West Tennessee. Surgical quality measures focused on intraoperative practice, with emphasis on pathologic nodal staging. We used descriptive statistics and trend analyses to assess changes in practice over time. To measure the effect of an ongoing regional quality improvement intervention with a lymph node specimen collection kit, we used period effect analysis to compare trends between the preintervention and postintervention periods. Of 2566 patients, 18% had no preoperative biopsy, only 15% had a preoperative invasive staging test, and 11% underwent mediastinoscopy. The rate of resections with no mediastinal lymph nodes examined decreased from 48%-32% (P < 0.0001), whereas the rate of resections examining 3 or more mediastinal stations increased from 5%-49% (P < 0.0001). There was a significant period effect in the increase in the number of N1, mediastinal, and total lymph nodes examined (all P < 0.0001). A quality improvement intervention including a lymph node specimen collection kit shows early signs of having a significant positive effect on pathologic nodal examination in this population-based cohort. However, gaps in surgical quality remain.

Initial multicenter community robotic lobectomy experience: comparisons to a national database.

BACKGROUND: In pulmonary lobectomy, video-assisted thoracoscopic surgery (VATS) offers advantages compared with open thoracotomy. However, various issues have limited its adoption, especially in community settings. Single surgeon studies suggest that completely portal robotic lobectomy (CPRL) may address such limitations. This multicenter study evaluates early CPRL experience in 6 community cardiothoracic surgeons' practices. METHODS: Perioperative data from each surgeon's initial 20, consecutive and unselected cases of CPRL were retrospectively gathered (total n = 120) and compared with the 2009 and 2010 Society of Thoracic Surgeons database for VATS (n = 4,612) and open (n = 5,913) lobectomy. The χ(2) and t test procedures were used and significance was defined at the 95% confidence level (p < 0.05). RESULTS: One hundred sixteen lobectomies (96.7%) were completed robotically with a conversion rate of 3.3%. Preoperative patient characteristics were comparable across the CPRL, VATS, and open groups. The CPRL was equivalent to VATS on all intraoperative and postoperative outcomes, and resulted in significantly lower postoperative blood transfusion rates (0.9% vs 7.8%; p = 0.002), air leaks greater than 5 days (5.2% vs 10.8%; p = 0.05), chest tube duration (3.2 days vs 4.8 days; p < 0.001), and length of stay (4.7 days vs 7.3 days; p < 0.001) when compared with open. For these outcomes, results trended favorably for CPRL over VATS. CONCLUSIONS: This early CPRL experience reveals a minimally invasive lobectomy technique that is safe and reproducible in varied practice settings. Outcomes were equivalent between CPRL and VATS, trending in favor of robotics. The CPRL was superior in several measures compared with open. The absence of patient selection and low conversion rates suggest a broad applicability of this technique.
