Failure to Monitor and Respond to Lithium Toxicity Leading to Resident Death
Summary
A deficiency occurred when the facility failed to ensure that services provided met professional standards of quality for a resident receiving lithium carbonate for schizoaffective disorder. Upon admission, the resident was alert and oriented, with a history of regular monthly blood work to monitor lithium levels during a prior hospital stay. The physician at the facility ordered a baseline lithium level, but the required blood draw was not completed as ordered. Nursing staff documented the blood draw as completed, but there was no evidence that it was actually performed, and no lab results were available. Attempts to obtain the blood sample were not documented in a timely manner, and late entries were added to the medical record over a month later, after the resident had been transferred out of the facility. There was also no documentation that the physician was notified of the failed blood draws or that any action was taken to address the lack of lab results. Despite the absence of required lithium level monitoring, the resident continued to receive daily doses of lithium. Over time, the resident exhibited multiple signs and symptoms consistent with lithium toxicity, including altered mental status, agitation, hallucinations, delusions, low blood pressure, nystagmus, and eventually unresponsiveness and seizure activity. These symptoms were documented in the medical record, but there was no evidence that the physician was notified of these significant changes in condition or that the medication was held in response to the observed symptoms. The facility had the option to send the resident to a hospital for the blood draw but did not do so after multiple failed attempts. Ultimately, the resident was transferred to the hospital in a severely compromised state, where laboratory testing revealed a critically high lithium level and acute renal failure. The resident was diagnosed with severe lithium toxicity, experienced multiple seizures, and suffered irreversible brain injury, leading to death. The facility's Director of Nursing Services confirmed failures in following physician orders, monitoring for toxicity, timely and accurate documentation, and appropriate communication with the physician regarding the resident's condition and lab work.
