Abstract

Background: Structured diagnosis (DX) are crucial for secondary use of electronic health record (EHR) data. However, they are often suboptimally recorded. Our previous work showed initial evidence of variable DX recording patterns in oncology charts even after biopsy records are available. Objective: We verified this finding's internal and external validity. We hypothesized that this recording pattern would be preserved in a larger cohort of patients for the same disease. We also hypothesized that this effect would vary across subspecialties. Methods: We extracted DX data from EHRs of patients treated for brain, lung, and pancreatic neoplasms, identified through clinician-led chart reviews. We used statistical methods (i.e., binomial and mixed model regressions) to test our hypotheses. Results: We found variable recording patterns in brain neoplasm DX (i.e., larger number of distinct DX- OR=2.2, P<0.0001, higher descriptive specificity scores-OR=1.4, P<0.0001-and much higher entropy after the BX-OR=3.8 P=0.004 and OR=8.0, P<0.0001), confirming our initial findings. We also found strikingly different patterns for lung and pancreas DX. Although both seemed to have much lower DX sequence entropy after the BX-OR=0.198, P=0.015 and OR=0.099, P=0.015, respectively compared to OR=3.8 P=0.004). We also found statistically significant differences between the brain dataset and both the lung (P<0.0001) and pancreas (0.009<P<0.08). Conclusion: Our results suggest that disease-specific DX entry patterns exist and are established differently by clinical subspecialty. These differences should be accounted for during clinical data reuse and data quality assessments but also during EHR entry system design to maximize accurate, precise and consistent data entry likelihood.
