Failure to Monitor and Respond to Lithium Toxicity Leading to Resident Death
Summary
A resident with a history of schizoaffective disorder and diabetes was admitted to the facility on lithium therapy, a medication with a narrow therapeutic range requiring regular blood level monitoring. Prior to admission, the resident had been receiving monthly lithium level checks during a prolonged hospital stay, with levels remaining mostly within the therapeutic range. Upon admission to the facility, a physician ordered a baseline lithium level, and nursing staff documented that the blood draw was completed; however, there was no evidence that the lab was actually obtained, and a late entry note was added to the record over a month later indicating unsuccessful attempts to draw blood. Despite the absence of lithium level results, the resident continued to receive daily doses of lithium. Over the following weeks, the resident exhibited multiple signs and symptoms consistent with lithium toxicity, including altered mental status, agitation, hallucinations, delusions, and eventually unresponsiveness and seizure activity. Nursing documentation showed that these changes in condition were not consistently reported to the physician, and there was no documentation of holding the lithium or seeking urgent evaluation as recommended in the presence of such symptoms. Multiple attempts to obtain a lithium level were unsuccessful, and the facility did not send the resident to an outside facility for the required blood draw, despite this being an available option. The resident continued to receive lithium without laboratory confirmation of safe levels, even after telemedicine consultation recommended obtaining a lithium level prior to further recommendations. Ultimately, the resident's condition deteriorated to the point of requiring emergency transfer to the hospital, where severe lithium toxicity, acute renal failure, and toxic encephalopathy were diagnosed. The resident's lithium level was found to be critically elevated, and the resident expired after a period of unresponsiveness and seizure activity. Interviews with facility leadership confirmed that critical lab monitoring was not completed as ordered, that there was a lack of timely physician notification regarding changes in the resident's condition, and that the facility failed to hold the medication or seek alternative means of obtaining necessary laboratory data.
