Background:Patients with severe hemophilia A and inhibitors are at risk of bleeding during invasive procedures. The standard of care for preventing perioperative bleeding has been replacement therapy with FVIII concentrates or for patients with high-titer inhibitors, bypassing agents. However, there is no consensus on the appropriate management of surgery in patients receiving the novel agent emicizumab. The aim of this study was to demonstrate a case of a patient on emicizumab undergoing major surgery with bypassing agents with preoperative use of the thrombin generation assay (TGA) and thromboelastography (TEG).Methods:We report a patient with hemophilia A with inhibitors who had undergone a total knee replacement while on emicizumab combined with a bypassing agent. We utilized TEG and TGA to determine which bypassing agent to choose as well as to inform about the ideal dose.Results:We elected to use recombinant FVIIa as a bypassing agent for the surgery based upon the TGA results.Conclusion:The TGA can be utilized to support decision-making in patients on emicizumab undergoing major surgery to both predict efficacy and potentially minimize the risk of thrombotic events.
Objective
Electronic consultation (eConsult) communications between primary care physicians (PCPs) and rheumatologists may reveal common knowledge gaps and educational opportunities. The aim of our study was to identify content themes in PCP questions and rheumatology recommendations through analysis of eConsult and the need for rheumatology appointments and facilitated urgent visits post‐eConsult.
Methods
A descriptive cross‐sectional study involving qualitative and quantitative analysis of rheumatology eConsults in a single center was performed from May 1, 2019, to January 9, 2020. Conventional content analysis was used to derive content themes in PCP questions and rheumatology recommendations. We evaluated the proportion of eConsults, which included a need for rheumatology appointments and expedited visits through frequency counts.
Results
Among 120 rheumatology eConsults, six PCP questions and five rheumatology recommendation content themes were identified. The most common PCP question themes were the following: 1) joint pain, 2) suspected rheumatic disease differential, and 3) abnormal laboratory tests. The most common rheumatology recommendation or teaching themes were the following: 1) education on differential diagnoses of rheumatic diseases, 2) education on the specific rheumatic disease, and 3) laboratory test interpretation. The majority of eConsults (82%) recommended a subsequent rheumatology appointment, and 27% facilitated an expedited appointment.
Conclusion
In this analysis of eConsults, we identified common knowledge gaps in PCPs and rheumatology educational topics, including differentiating inflammatory from noninflammatory arthritis, using caution in interpreting abnormal laboratory tests without clinical manifestations, managing chronic gout, evaluating elevated creatine phosphokinase levels, and differentiating C‐reactive protein (CRP) from high‐sensitivity CRP. Timely feedback through eConsult recommendations may allow for focused educational opportunities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
