Failure to oversee water management program and respond to Legionella exposure
Summary
The facility administration failed to provide effective oversight to ensure ongoing implementation of its water management program after a resident was diagnosed with Legionnaires’ Disease and was believed by the Department of Health to have been symptomatic while staying at the facility for the entire incubation period. The Administrator, DON/Infection Preventionist, and Maintenance Director were identified as key staff responsible for operations, infection prevention, and maintenance, and the facility’s own Water Management Program assigned responsibility to a committee including the Administrator, DON, Medical Director, and Maintenance Supervisor. The report states that the DON did not oversee the water management program as part of infection prevention and did not initiate preventive measures when notified of the diagnosis, and the Administrator did not implement the interventions listed in the facility’s Water Management Plan when informed of the diagnosis. The facility’s water system had multiple deficiencies identified during the survey. The facility had 3 mixing valves for 7 water heaters, and all 3 mixing valves were non-operational. Five of the 7 water heater temperature gauges were non-functional. The circulation pump on the Tarpon Unit was unplugged, and water temperatures in the tanks ranged from 114 degrees F to 117 degrees F. The Maintenance Director stated that the mixing valves had been non-operational since he began working at the facility 6 years earlier and that no attempts had been made during that time to repair them. Documentation of a water system risk assessment and monitoring such as visual inspection, temperature checks, and disinfectant checks was requested but not provided. The facility also did not promptly implement the Department of Health’s recommendations after being notified of the possible Legionella exposure. The DOH informed the facility that the resident became symptomatic while staying there and that environmental conditions could support Legionella growth in the plumbing. The DOH recommended professional consultation, maintaining domestic hot water at a minimum of 140 degrees F, flushing shower and sink faucets, and allowing showerheads to hang to fully drip out. The facility’s Safety Committee did not meet until 14 days after the diagnosis notification, and the Performance Improvement Plan did not include all of the DOH recommendations. The room occupied by the resident had a showerhead tucked between the wall and handrail rather than hanging to drip out, and later environmental testing from the resident’s room and another room was positive for Legionella pneumophila.
