The RHD allele, RHD*148+1T, results in a partial Del phenotype, and the anti-D formed in pregnant women with this phenotype is capable of causing severe HDFN.
Adenoviral‐vector based vaccines for coronavirus disease 2019 (COVID‐19) have been linked with a thrombotic syndrome, vaccine‐induced thrombotic thrombocytopenia (VITT). A key clinical question is whether VITT can be reliably ruled out by the absence of thrombocytopenia. We report on three patients who presented to our institute with this syndrome. Noteworthy in our presentations are two patients who presented for medical assessment of thrombotic symptoms with a normal platelet count, one preceding and one following a period of thrombocytopenia. Prompt diagnosis of VITT is critical to prevent rapid patient decline. We provide herein a new diagnostic algorithm that we believe will help optimally capture case presentations of VITT. These cases broaden and refine our understanding of the disease process and highlight to practitioners that VITT cannot be adequately ruled out by thrombocytopenia alone.
Background
Laboratory stewardship programs aim to improve the use of laboratory resources, including reducing inappropriate testing. These programs should engage all healthcare stakeholder groups, including all levels of laboratory staff. Medical laboratory technologists (MLTs) are highly skilled professionals and are well positioned to play a supportive role in stewardship but may be overlooked. The aim of this study is to identify the barriers to MLT participation in stewardship activities.
Methods
We developed and disseminated a self-administered survey to MLTs in Canada to assess their knowledge and attitudes toward inappropriate laboratory utilizatioz and explore perceived barriers to taking on an active role in stewardship initiatives. Themes were identified in open-ended responses and mapped to the Theoretical Domains Framework (TDF).
Results
MLTs feel accountable for helping ensure appropriate resource use and recognize that it is an important issue to address. However, they experience significant barriers and have low intention to act. The self-reported barrier most frequently described was lack of time arising from excessive workloads, but other constraints exist. Themes mapped to the TDF most strongly in the domain of environmental context and resources, supporting evidence that workplace structure and culture play key roles in impacting this group.
Conclusions
To meaningfully engage MLTs in stewardship activities, these barriers should be addressed. Highlighting MLT expertise and creating communication structures and opportunities for their unique contributions may be fruitful.
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.
