Validation of the Combined Comorbidity Index of Charlson and Elixhauser to Predict 30-Day Mortality Across ICD-9 and ICD-10
OBJECTIVES: To validate and compare performance of an International Classification of Diseases, tenth revision (ICD-10) version of a combined comorbidity index merging conditions of Charlson and Elixhauser measures against individual measures in the prediction of 30-day mortality. To select a weight derivation method providing optimal performance across ICD-9 and ICD-10 coding systems. RESEARCH DESIGN: Using 2 adult population-based cohorts of pa…
Near Real-time Surveillance for Consequences of Health Policies Using Sequential Analysis
BACKGROUND: New health policies may have intended and unintended consequences. Active surveillance of population-level data may provide initial signals of policy effects for further rigorous evaluation soon after policy implementation. OBJECTIVE: This study evaluated the utility of sequential analysis for prospectively assessing signals of health policy impacts. As a policy example, we studied the consequences of the widely publicized Food and Dr…
Adaptation and Validation of the Combined Comorbidity Score for ICD-10-CM
BACKGROUND: The combined comorbidity score, which merges the Charlson and Elixhauser comorbidity indices, uses the ninth revision of the International Classification of Diseases, Clinical Modification (ICD-9-CM). In October 2015, the United States adopted the 10th revision (ICD-10-CM). OBJECTIVE: The objective of this study is to examine different coding algorithms for the ICD-10-CM combined comorbidity score and compare their performance to the …

Privacy-preserving Analytic Methods for Multisite Comparative Effectiveness and Patient-centered Outcomes Research
BACKGROUND: For privacy and practical reasons, it is sometimes necessary to minimize sharing of individual-level information in multisite studies. However, individual-level information is often needed to perform more rigorous statistical analysis. OBJECTIVES: To compare empirically 3 analytic methods for multisite studies that only require sharing of summary-level information to perform statistical analysis that have traditionally required access…
The Prevalence and Trends of Antiviral Medication Use During Pregnancy in the US
Data Quality Assessment for Comparative Effectiveness Research in Distributed Data Networks
BACKGROUND: Electronic health information routinely collected during health care delivery and reimbursement can help address the need for evidence about the real-world effectiveness, safety, and quality of medical care. Often, distributed networks that combine information from multiple sources are needed to generate this real-world evidence. OBJECTIVE: We provide a set of field-tested best practices and a set of recommendations for data quality c…
Confounding Adjustment in Comparative Effectiveness Research Conducted Within Distributed Research Networks
BACKGROUND: A distributed research network (DRN) of electronic health care databases, in which data reside behind the firewall of each data partner, can support a wide range of comparative effectiveness research (CER) activities. An essential component of a fully functional DRN is the capability to perform robust statistical analyses to produce valid, actionable evidence without compromising patient privacy, data security, or proprietary interest…
