Patient-controlled analgesia (PCA) appears to be the preferred modality for treatment of pain associated with vaso-occlusive crisis (VOC) and is the current standard of therapy at most institutions. With limited data available, this study analyzed the effectiveness of PCA vs intravenous push (IVP) hydromorphone for pain management of VOC. The primary objective was to determine whether PCA or IVP hydromorphone is more effective in controlling VOC pain determined by a reduction in mean absolute difference pain intensity (MPI) from baseline to discharge. This retrospective single-center study evaluated differences in outcomes between patients treated with PCA vs those treated with IVP hydromorphone for VOC during hospital admission. Those 18 years or older admitted with one of the following International Classification of Diseases, Tenth Revision codes were included: D57.0 (Hb-SS disease with crisis), D57.2 (sickle cell/Hb-C disease), and D57.4 (sickle cell thalassemia), and administered PCA or IVP hydromorphone. The observed difference in absolute pain scores were not statistically significant ( p  = 0.753). The use of IVP hydromorphone resulted in a significant reduction in length of stay (LOS) and morphine milligram equivalent (MME) use compared to PCA, but was associated with a numerical increase in treatment failures. This study was limited by its retrospective nature, uneven distribution of groups, and only reviewed use of IVP and PCA hydromorphone at one institution.
