Failure to Manage Legionella in Water System and Report Positive Findings
Summary
The facility failed to provide and implement its infection prevention and control program in relation to Legionella bacteria found in the water system. Multiple Annual Analytical Validation Viable Legionella Bacteria Reports dated from 2/26/2024 through 3/17/2025 showed detectable Legionella in domestic water samples, including samples from resident rooms and Bathtub 1. The reports included recommendations to flush positive fixtures and adjacent taps, verify hot water temperature, replace affected showerheads and hose lines, descale or disinfect fixtures, re-test positive locations after corrective actions, and consider additional control measures when repeated positives continued. The facility’s Water Management Program Water Safety Plan also stated that affected fixtures could be isolated and that water should be re-sampled after corrective actions, but the report states the facility did not follow or act on these recommendations and there was no documented evidence that the actions were implemented. The Infection Preventionist Nurse stated she did not carry out her role in managing Legionella and did not maintain logs showing whether residents were monitored for potential exposure. She also stated she was not aware the facility’s water tested positive on 2/26/2024 and only learned of later results after the previous administrator informed her. The DON stated she was not aware of the 3/17/2025 positive water test and that there was no documented evidence the facility monitored residents for Legionella exposure. The DON and IP Nurse also stated the facility failed to implement and follow the water management plan recommendations, and the DON stated the presence of Legionella in the water system was not reported to CDPH. Resident 1 was admitted with COPD and type 2 DM and was severely impaired in thought processes and dependent for ADLs. On 10/25/2025, Resident 1 had a change in condition with altered mental status, fever, shortness of breath, and unresponsiveness, and was transferred to a GACH. The hospital record showed Resident 1 underwent a Legionella pneumoniae sputum procedure that detected Legionella bacteria. The report also states the facility failed to ensure communication between the previous and current administrators regarding the positive Legionella findings, and the current administrator stated he was not aware of the water test results because they had been reported to the previous administrator.
