A comparison of two distribution methods on response rates to a patient safety questionnaire in nursing homes.
BACKGROUND
Survey research focusing on patient safety issues in the nursing home sector poses challenges owing to nursing staff turnover rates, and the adversarial and punitive nature of US nursing home regulation which may promote a negative culture of distrust. Using a patient safety questionnaire, we compared two methods of survey distribution on response rates, respondent sample characteristics, and resident safety ratings. We hypothesized that employees may provide overly positive perceptions when the surveys are distributed on-site as opposed to distribution to employees' homes, as has been reported by studies evaluating patient satisfaction in other settings.


METHODS
In August 2003, 26 nursing homes indicated their distribution method preference (mail directly to staff members' homes vs. distributed at work) for a survey determining perceptions of resident safety. Facilities provided lists of currently employed nurses (n=721) and nursing assistants (n=1,233). The survey process included an initial mailing of the survey packet, a reminder postcard, a re-mail of the survey packet to non-respondents to the initial survey, and a final reminder postcard. Return envelopes were addressed to the research team.


RESULTS
In nursing facilities where surveys were distributed at work, a greater proportion of respondents were identified as no longer currently employed. Response rates were similar regardless of distribution method, but with greater variability in the facility-specific response rate in surveys distributed at work. Regardless of staffing type, yield of the first mailing was lower and yield of the second mailing higher in homes with surveys distributed at work than those mailed directly to respondents' homes. While characteristics of nurses were similar regardless of wave, nursing assistant responders to second mailing were more likely to be black relative to responders to the first wave.


CONCLUSIONS
Distributing surveys at the workplace may not result in a reduction of response rate, but may provide overly positive perceptions of patient safety issues. Mailing directly to homes may result in less facility-level variability in response rates. Multiple mailings may increase the diversity of the respondent pool.
