Failure to Follow CDC Legionella Water Testing Protocols and Filter Replacement Guidelines
Penalty
Summary
The facility failed to follow CDC guidance for environmental water testing and manufacturer instructions for point-of-use sink filters after a resident was reported positive for Legionella while hospitalized. After notification of the positive Legionella case, the DON communicated with a state epidemiologist and was informed that water cultures should be collected every two weeks for three months, followed by monthly testing for three additional months if no Legionella was detected. CDC guidance also specified that each water sample from sinks, showers, and other sites should be 1 liter (1000 ml). However, the facility initially collected water samples using only 100 ml per site, which was 900 ml less than the recommended volume, and this occurred on multiple testing dates. In addition to using insufficient sample volumes, the facility did not adhere to the required testing frequency. Although the facility believed it was testing every two weeks in December and January, it was doing so with the wrong sample volume. From January through March, the facility tested only monthly instead of every two weeks as directed by CDC guidance. Communication from the state infectious disease assistant director later confirmed that the early tests with 100 ml volumes and the later tests performed almost a month apart were inadequate and would not count toward the required monitoring sequence. The facility’s Water Management Policy did not specify the required volume and frequency of surveillance testing after a confirmed positive Legionella case. The facility also failed to replace point-of-use Nephros S100 sink filters within the 90-day operational period specified by the manufacturer. Observations showed that the filters were installed when the facility was first notified of the positive Legionella case and had not been changed by the time of survey, despite the manufacturer’s instructions that the filters should operate for up to three months of normal use. The Director of Maintenance confirmed that the filters had remained in place since installation and had expired based on the 90-day use guidance. The DON further explained that the facility relied on the “use by” date on the filter box (2028) rather than the 90-day operational limit, and the facility’s Infection Prevention and Control Program, although generally outlining surveillance and outbreak response expectations, did not provide specific direction on Legionella testing volume and frequency after a confirmed case.
