P1.12-001 - Trends in Accuracy and Comprehensiveness of Pathology Reports of Resected Non-Small Cell Lung Cancer (NSCLC) in a High Mortality Area of the US (ID 1571)
09:30 - 09:30 | Author(s): D. Spencer
- Abstract
Background:
Pathologic examination of NSCLC resection specimens is vital to optimal treatment. In 2004, the College of American Pathologists (CAP) issued guidelines for NSCLC reporting, which were most recently updated in 2013. We evaluated the adoption of CAP reporting elements in a regional database.
Methods:
The Mid-South Quality of Surgical Resection (MS-QSR) database includes detailed information on 2,593 NSCLC resections in 11 institutions in 5 Dartmouth Hospital Referral Regions in Eastern Arkansas, North Mississippi and Western Tennessee from 2009-2014. In 2009, we started a multifaceted educational intervention: 1. Analyzed 2004-2008 pathology reports demonstrating the quality deficit in pathology reporting. 2. Recommended adoption of synoptic reporting of CAP checklist items. 3. Embedded a surgical intervention to improve mediastinal lymph node examination at some institutions. To allow for comparisons between eras and across the post-intervention era by intervention and type of hospital, we evaluated 4 groups: pre-intervention (pre-int), post-intervention participating hospital with surgical intervention (post-int/surg), post-intervention participating hospital without surgical intervention (post-int/non-surg), and non-participating non-surgical intervention hospital (post-int/non-part). We evaluated the inclusion of each CAP checklist item and the percent of cases with all items and 6 key items reported. We also evaluated the accuracy of T and N-stage categorization. Proportions reporting each item were compared between groups using Fisher’s Exact test.
Results:
Details of the completeness of pathology reporting are shown in Table 1 by group. The percent reporting the 6 key checklist items improved significantly from 63% pre-int to 76% post-int/non-part, 86% post-int/non-surg, and 95% post-int/surg (p-value<0.0001). A similar pattern of improvement was observed for N-stage (p-value<0.0001) and T-stage (p-value<0.0001) reporting. However, we observed significant decreases in the reporting of M-stage, and therefore all key items, post-intervention (p-value<0.0001). The accuracy of N-stage reporting improved significantly from 66% pre-int to 72% post-int/non-part, 86% post-int/non-surg, and 97% post-int/surg (p-value<0.0001). A similar trend was observed for T-stage accuracy (p-Value<0.0001).%Reporting Pre-Int (N=1390) Post-Int/ Non-Part (N=271) Post-Int/ No-Surg (N=645) Post-Int/ With-Surg (N=310) P-Value Specimen* 98.4 100 100 100 <0.0001 TumorSize* 97.2 99.6 98.1 99.4 0.0094 Histology* 99.8 99.6 99.5 99.7 0.59 MarginStatus* 97.1 98.5 92.6 98.7 <0.0001 T-Stage* 67.8 76.4 92.1 97.1 <0.0001 N-Stage* 66.3 76.8 89.8 97.7 <0.0001 *All Key-Items 62.7 75.7 85.7 94.8 <0.0001 Laterality 99.8 100 99.5 100 0.56 HistologicGrade 99.9 100 99.5 100 0.18 M-Stage 75.8 31.4 25 21.6 <0.0001 VascularInvasion 28.6 10.7 25 11.9 <0.0001 All Items 10.7 4.1 6.2 3.2 <0.0001 %Accurate N-Stage 66.2 71.6 86.2 96.8 <0.0001 T-Stage 55.3 61.6 83 84.8 <0.0001
Conclusion:
There was significant improvement in reporting of CAP checklist items and the accuracy of pT- and pN-categorization. After the introduction of synoptic reporting, we observed a secular trend of improvement, shown by our post-int/non-part external control. Direct educational intervention in 2009-2010 further improved the completeness and accuracy of reports in participating hospitals. The surgical intervention provided additional benefit. Interventions to improve the quality of reporting for NSCLC are impactful on accuracy and thoroughness of reporting, thereby improving the quality of care.
