Sickle Cell Disease Associated Pain, Diagnosed

The concept set was generated by searching for terms that related to pain in a SCD subset population. The code set is a part of a clinical variable definition for inpatient hospitalization. To be classified with pain hospitalization, a patient needs to have at least one occurrence of diagnosis code in the inpatient visit OR two exposures to opioids on separate days. Face validity was checked using manual review on a small subset of patient. 100% specificity and sensitivities were seen. <br> NOTE : This code set is only application for pain hospitalizations in SCD population. The code sets should be expanded to explore coding practices at other institutions as it was validated against CHOP's data only.
