Five nurses have been disciplined by the state Board of Examiners for Nursing for misconduct ranging from sleeping on the job to abusing heroin or stealing from patients. The board last Wednesday suspended the registered nursing license of Adrian Kozikowski of New Britain because, state records show, he left a shift in July at Autumn Lake Healthcare in New Britain and fell asleep or lost consciousness due to drug use. Between April and July, he abused alcohol, marijuana and Ecstacy, records show, so the state Department of Public Health concluded his practice as a nurse posed a “clear and immediate danger” to the public. The board also suspended the license of Lisa Fabrizio, an RN from Monroe after concluding that she posed a danger as well. While working at Lighthouse Home Healthcare in Old Saybrook, she took property from the home and residents between March and May, records show.
