Bilirubin Elevation Caused by Naproxen Overdose: A Case Report Highlighting Laboratory Interference.

BACKGROUND Overdoses on over-the-counter (OTC) drugs are increasing in the United States, which includes widely available non-steroidal anti-inflammatory drugs (NSAIDs) like naproxen. Symptoms of NSAID toxicity are well known and nonspecific, including nausea, vomiting, abdominal pain, and headaches. Extreme cases can present with confusion, seizures, and renal failure. CASE REPORT We present the case of 63-year-old man with a history of hyperthyroidism and polysubstance use who had an elevated total bilirubin level after attempting suicide via ingestion of 16 tablets of naproxen. The patient presented with vague abdominal pain and nausea in the setting of 2 weeks of worsening psychiatric symptoms, including suicidal ideation. Vital signs, physical examination, and review of systems revealed no significant findings. Medical workup was notable only for an elevated total bilirubin level; workup for hemolysis, biliary stasis, hepatic dysfunction was all within normal limits. Direct bilirubin was not elevated. The patient received intravenous fluids and antiemetic medications, and indirect hyperbilirubinemia resolved by the following day. After ruling out other causes of hyperbilirubinemia, it was determined that his elevated bilirubin was due a naproxen metabolite, O-desmethylnaproxen (ODMN), that has been shown to interfere with certain bilirubin assays when naproxen is ingested over the therapeutic dose. CONCLUSIONS Supratherapeutic naproxen ingestion can lead to laboratory findings of elevated total bilirubin in some assays due to ODMN interference. With the rise in suicide attempts in the United States with OTCs, clinicians should consider laboratory error in such clinical circumstances where the clinical data does not fit the history and physical examination.

Does Psychological Safety Impact the Clinical Learning Environment for Resident Physicians? Results From the VA's Learners' Perceptions Survey.

BACKGROUND: Psychological safety (PS) is the perception that it is safe to take interpersonal risks in the work environment. In teaching hospitals, PS may influence the clinical learning environment for trainees. OBJECTIVE: We assessed whether resident physicians believe they are psychologically safe, and if PS is associated with how they rate satisfaction with their clinical learning experience. METHODS: Data were extracted from the Learners' Perceptions Survey (LPS) of residents who rotated through a Department of Veterans Affairs health care facility for academic years 2011-2014. Predictors of PS and its association with resident satisfaction were adjusted to account for confounding and response rate biases using generalized linear models. RESULTS: The 13 044 respondents who completed the LPS (30% response rate) were comparable to nonpediatric, non-obstetrics-gynecology residents enrolled in US residency programs. Among respondents, 11 599 (89%) agreed that ". . . members of the clinical team of which I was part are able to bring up problems and tough issues." Residents were more likely to report PS if they were male, were in a less complex clinical facility, in an other medicine or psychiatry specialty, or cared for patients who were aged, had multiple illnesses, or had social supports. Nonpsychiatric residents felt safer when treating patients with no concurrent mental health diagnoses. PS was strongly associated with how residents rated their satisfaction across 4 domains of their clinical learning experience (P < .001). CONCLUSIONS: PS appears to be an important factor in resident satisfaction across 4 domains that evaluators of graduate medical education programs should consider when assessing clinical learning experiences.

"Page Me if You Need Me": The Hidden Curriculum of Attending-Resident Communication.

BACKGROUND: Discrepancies exist between what resident and attending physicians perceive as adequate supervision. We documented current practices in a university-based, categoric, internal medicine residency to characterize these discrepancies and the types of mixed messages that are communicated to residents, as well as to assess their potential effect on resident supervision and patient safety. METHODS: We surveyed residents and attending physicians separately about their current attitudes and behaviors regarding resident supervision. Both groups responded to 2 different measures of resident supervision: (1) 6 clinical vignettes that involved patient safety concerns, and (2) 9 frequently reported phrases communicated by attending physicians to residents before leaving the hospital during on-call admission days. RESULTS: There were clear and substantial differences between the perceptions of resident and attending physicians about when the supervising attending physician should be notified in each of the 6 vignettes. For example, 85% of attending physicians reported they wanted to be notified of an unexpected pneumothorax that required chest tube placement, but only 31% of resident physicians said they would call their attending physician during those circumstances. Common phrases, such as "page me if you need me," resulted in approximately 50% of residents reporting they would "rarely" or "never" call and another 41% reporting they would only "sometimes" call their attending physicians. CONCLUSIONS: Our study found that attending physicians reported they would want more frequent communication and closer supervision than routinely perceived by resident physicians. Although this discrepancy exists, commonly used phrases, such as "page me if you need me," rarely resulted in a change in resident behavior, and attending physicians appeared to be aware of the ineffectiveness of these statements. These mixed messages may increase the difficulty of balancing the dual goals of appropriate attending supervision and progressive independence during residency training.
