Show moreAims and ObjectivesStudies in adult medicine have shown that physicians base testing decisions on the patient's clinical condition but also consider other factors, including local practice or patient expectations. In pediatrics, physicians and parents jointly decide on behalf of a (young) child. This might demand more explicit and more complex deliberations, with sometimes conflicting interests. We explored pediatricians' considerations in diagnostic test ordering and the factors that influence their deliberation. MethodWe performed in-depth, semistructured interviews with a purposively selected heterogeneous sample of 20 Dutch pediatricians. We analyzed transcribed interviews inductively using a constant comparative approach, and clustered data across interviews to derive common themes. ResultsPediatricians perceived test-related burden in children higher compared with adults, and reported that avoiding an unjustified burden causes them to be more restrictive and deliberate in test ordering. They felt conflicted when parents desired testing or when guidelines recommended diagnostic tests pediatricians perceived as unnecessary. When parents demanded testing, they would explore parental concern, educate parents about harms and alternative explanations of symptoms, and advocate watchful waiting. Yet they reported sometimes performing tests to appease parents or to comply with guidelines, because of feared personal consequences in the case of adverse outcomes. ConclusionWe obtained an overview of the considerations that are weighed in pediatric test decisions. The comparatively strong focus on prevention of harm motivates pediatricians to critically appraise the added value of testing and drivers of low-value testing. Pediatricians' relatively restrictive approach to testing could provide an example for other disciplines. Improved guidelines and physician and patient education could help to withstand the perceived pressure to test. Show less

Show moreBackground The diagnostic accuracy of clinical probability assessment and D-dimer testing for clinically suspected recurrent deep vein thrombosis (DVT) is largely unknown. Aim To evaluate the safety of ruling out acute recurrent DVT based on an unlikely Wells score for DVT and a normal D-dimer test. Methods This was a predefined endpoint of the Theia study in which the diagnostic accuracy of magnetic resonance direct thrombus imaging in acute recurrent ipsilateral DVT was validated. The Wells rule and D-dimer test, performed as part of the study protocol, were not used for management decisions. The primary outcome of this analysis was the incidence of recurrent DVT at baseline or during 3-month follow-up for patients with an unlikely Wells score and a normal D-dimer test. Results Results of both Wells score and D-dimer tests were available in 231 patients without anticoagulant treatment. The recurrent DVT prevalence was 45% (103/231). Forty-nine patients had an unlikely Wells score and normal D-dimer test, of whom 3 (6.1%, 95% confidence interval [CI] 1.3%-18%) had recurrent DVT at baseline/follow-up, yielding a sensitivity of 97% (95% CI 92%-99%) and specificity of 36% (95% CI 28%-45%). Thus, if clinical probability scoring and D-dimer testing would have been applied, radiological imaging could have been omitted in 21% of patients with a diagnostic failure rate of 6.1%. Conclusion By applying clinical probability scoring and D-dimer testing, radiological imaging could be spared in one fifth of patients with suspected recurrent ipsilateral DVT. However, the high failure rate does not support implementation of this strategy in daily practice. Show less

Show moreOBJECTIVES As a person's age increases and his/her health status declines, new challenges arise that may lead physicians to consider deprescribing statins. We aimed to provide insight into recommendations available in international cardiovascular disease prevention guidelines regarding discontinuation of statin treatment applicable to older adults. DESIGN We systematically searched PubMed, EMBASE, EMCARE, and the websites of guideline development organizations and online guideline repositories for cardiovascular disease prevention guidelines aimed at the general population. We selected all guidelines with recommendations (instructions and suggestions) on discontinuation of statin treatment applicable to older adults, published between January 2009 and April 2019. In addition, we performed a synthesis of information from all other recommendations for older adults regarding statin treatment. Methodological quality of the included guidelines was appraised using the appraisal of guidelines for research & evaluation II (AGREE II) instrument. RESULTS Eighteen international guidelines for cardiovascular disease prevention in the general adult population provided recommendations for statin discontinuation that were applicable to older adults. We identified three groups of instructions for statin discontinuation related to statin intolerance, and none was specifically aimed at older adults. Three guidelines also included suggestions to consider statin discontinuation in patients with poor health status. Of the 18 guidelines included, 16 made recommendations regarding statin treatment in older adults, although details on how to implement these recommendations in practice were not provided. CONCLUSION Current international cardiovascular disease prevention guidelines provide little specific guidance for physicians who are considering statin discontinuation in older adults in the context of declining health status and short life expectancy.
