BackgroundDespite the use of ‘patient ownership’ as an embodiment of professionalism and increasing concerns over its loss among trainees, how its development in residents has been affected by duty hour regulations has not been well described. In this qualitative study, we aim to outline the key features of patient ownership in internal medicine, factors enabling its development, and how these have been affected by the adoption of a night float system to comply with duty hour regulations.MethodsIn this qualitative descriptive study, we interviewed 18 residents and 12 faculty internists at one university centre and conducted a thematic analysis of the data focused on the concept of patient ownership.ResultsWe identified three key features of patient ownership: personal concern for patients, professional capacity for autonomous decision-making, and knowledge of patients’ issues. Within the context of a night float system, factors that facilitate development of patient ownership include improved fitness for duty and more consistent interactions with patients/families resulting from working the same shift over consecutive days (or nights). Conversely, the increase in patient handovers, if done poorly, is a potential threat to patient ownership development. Trainees often struggle to develop ownership when autonomy is not supported with supervision and when role-modelling by faculty is lacking.DiscussionThese features of patient ownership can be used to frame discussions when coaching trainees. Residency programs should be mindful of the downstream effects of shift-based scheduling. We propose strategies to optimize factors that enable trainee development of patient ownership.Electronic supplementary materialThe online version of this article (10.1007/s40037-019-00540-9) contains supplementary material, which is available to authorized users.
Introduction: Hypervitaminosis D is a relatively uncommon etiology of hypercalcemia. Toxicity is usually caused by very high doses, mostly secondary to erroneous prescription or administration of Vitamin D, and less commonly, contaminated foods or manufacturing errors of vitamin D-containing supplements. Case description: 16 year old male, previously healthy, presented with 2-week history of non specific symptoms (fatigue, gastrointestinal complaints). Investigations showed acute kidney injury and hypercalcemia (total calcium 3.81 mmol/L). Further diagnostic workup revealed markedly elevated 25-hydroxy-vitamin D levels (1910 nmol/L). He denied taking any vitamin D supplements; however, he reported consumption of creatine and protein supplements. Mass spectrometry analysis of the creatine supplement estimated a vitamin D content of 425,000 IU per serving (100 times the upper tolerable daily dose). A few months later, another previously healthy adolescent presented with severe hypercalcemia and acute kidney injury secondary to hypervitaminosis D. He was also using a creatine supplement from the same manufacturer brand and lot. Both patients were treated with IV hydration, calcitonin and pamidronate. They maintained normocalcemia after their initial presentation but required low-calcium diets and laboratory testing for months after this exposure. Discussion: We present 2 cases of hypervitaminosis D caused by a manufacturing error of a natural health product which did not claim to contain vitamin D. The use of dietary supplements is highly prevalent; their use should be incorporated in anamnesis and considered a potential source of toxicity when an alternative source cannot be found, regardless of the product label.
