Advanced Center: Legionella Testing Failures - CT

Advanced Center for Nursing & Rehabilitation botched its response when notified of a positive legionella case, according to a March 31 state inspection. The facility's Director of Nursing admitted they had been testing with only 250 milliliters of water when guidelines required 1,000 milliliters for each sample.

The volume error persisted through December and January testing rounds. Even after staff learned they needed larger water samples, the facility continued missing testing frequency requirements from January through March, conducting monthly tests instead of the required bi-weekly schedule.

"I did not think they had to continue testing every two weeks because their first test was negative," the Director of Nursing told inspectors. She was wrong. Guidelines required bi-weekly testing for three months from the start of proper volume testing.

The facility installed point-of-use filters on all sinks and showers when the positive case was discovered, along with bringing in bottled water for residents. But those safety measures also failed proper maintenance protocols.

Filters expired ninety days after installation, but staff never replaced them. The Director of Maintenance said the facility "had not changed the filters but was going to replace them since they were expiring." He noted the filters were actually installed when the facility was first notified of the positive legionella case, meaning they had been operating with expired filtration for an unknown period.

The Director of Nursing explained staff had been following expiration dates printed on filter boxes, which showed a 2028 use-by date, rather than the manufacturer's ninety-day operational limit from installation. She told inspectors she would contact the manufacturer for guidance and ensure future replacements followed proper timelines.

Legionella bacteria can cause severe pneumonia and death, particularly in elderly residents with compromised immune systems. Proper water testing and filtration are critical safety measures in nursing homes, where residents may have limited ability to avoid contaminated water sources.

The facility's own policies required robust infection control measures. Their Infection Prevention and Control Program, last revised in September 2025, directed staff to "implement an ongoing, data-driven infection prevention and control program" and "maintain ongoing infection surveillance using standardized definitions."

The policy specifically required staff to "initiate immediate control measures, notify Connecticut DPH, the medical director and administrator immediately upon suspicion" and "maintain a line list, exposure log, and documentation of interventions and outcomes."

But the facility's Water Management Policy failed to specify proper volume and frequency requirements for surveillance testing after confirmed positive legionella cases, leaving staff without clear guidance during the crisis response.

The testing failures meant the facility couldn't accurately assess whether their mitigation efforts were working. Insufficient water samples could miss bacteria present in the system, while infrequent testing created gaps where contamination might go undetected for weeks.

State inspectors found the problems affected many residents, though the specific number wasn't detailed in the report. The facility serves as both a nursing home and rehabilitation center, housing residents who may stay for extended periods or shorter-term recovery.

The Administrator and Director of Nursing told inspectors they began "immediate mitigation strategies" when notified of the positive case, including water testing, bottled water distribution, and filter installation. But their execution of those strategies fell short of safety requirements designed to protect vulnerable residents.

The facility's response revealed gaps in staff understanding of legionella protocols. The Director of Nursing's assumption that one negative test meant reduced monitoring showed a fundamental misunderstanding of infection control principles for this dangerous bacteria.

Inspectors classified the violations as causing minimal harm or potential for actual harm to residents. But the months-long testing failures created ongoing risk that proper protocols are designed to prevent.

The facility now faces questions about whether other infection control procedures meet required standards, and whether staff training adequately prepares them to respond to future health emergencies that could threaten resident safety.
