Pitfalls and Unexpected Benefits of an Electronic Hand Hygiene Monitoring System.

BACKGROUND

No single strategy is more effective than proper hand hygiene (HH) in reducing the spread of nosocomial infections. Unfortunately, health care worker compliance with HH is imperfect. We sought to improve HH compliance using an electronic hand hygiene monitoring system (EHHMS) in 2 units to collect unbiased data and provide feedback.

METHODS

In this prospective, quasi-experimental study, the Hyginex EHHMS was installed in 2 units at Tufts Medical Center. Ninety-one bracelets were assigned, and electronic data were collected over 8 months. Human observations continued. We compared HH compliance as measured by human observation before, during, and after EHHMS implementation. Pre- and post-implementation surveys were distributed to staff.

RESULTS

The number of electronically captured HH compliance observations was small due to infrequent bracelet use after month 2 of the intervention. HH compliance, as determined by human observation, increased by an average of 1.3 percentage points per month (P = .0005). Survey responses revealed negative attitudes about the EHHMS before and after its implementation.

CONCLUSIONS

Despite poor EHHMS participation and negative attitudes toward its implementation, HH compliance, as measured by human observation, significantly improved. Hospitals considering implementing an EHHMS should look to refine the intervention to encourage health care worker participation.
