P1.07 External Peer Review of the Western New South Wales Lung Cancer Service – A Unique Regional and Rural AUN Experience

Abstract

using "breast cancer" and "national cancer database" and another using "lung cancer" and "national cancer database." The data was combined to determine each variables' association with journal impact factor using both univariate and multivariate analyses. P< 0.05 was considered as statistically significant. Results: A total of 191 published studies were identified. We found that a journal impact factor > 5 was associated with a publication year prior to 2017 (univariate analysis OR 2.68, 95% CI 1.38-5.21, p-value 0.004 and multivariate analysis OR 3.47, 95% CI 1.62-7.42, p-value 0.001) and a sample size > 10,000 (univariate analysis OR 3.27, 95% CI 1.43-7.50, p-value 0.005 and multivariate analysis OR 4.68, 95% CI 1.89-11.6, p-value 0.0008). Variables such as number of authors (5 vs. >5), region (US vs. non-US), cancer type (lung vs. breast), stage (including vs. excluding stage IV), treatment outcome (yes vs. no) and treatment incidence (yes vs. no) were not significant for an association with an impact factor > 5. Conclusion: Based on our data, studies published after 2017 using the NCDB were associated with a lower impact factor. This could suggest that the quality of the NCDB data may be declining over time.
