Methods: The project used a quantitative research method with a quasi-experimental nonequivalent control group to test the effectiveness of a web-based influenza virus and vaccination professional educational module in HealthStream®. Because both the comparison group and the intervention group were convenience (non-randomized) samples, a quasi-experimental design was necessary. The participants self-selected. The groups were pre-existing and nonequivalent. The selection of this design was most appropriate for this study because it offered a larger cross section of nurses. This design also limited the potential for interaction between the two groups of participants and limited any potential bias. A brief anonymous paper survey method limited the participant’s time commitment required for completion but allowed for collection of sufficient data to gain insight into similarities, differences, and trends to make predictions about the sample population. The anonymous survey also allowed for data collection from a large population without cumbersome effort on my part. Lastly, the selection of this method will allow continued data collection with the same methodology with other groups of participants in future studies.
The web-based educational module was developed to address knowledge gaps identified from the literature. The program was made available to all RNs through an existing internal web-based computerized program, HealthStream®. This approach was a familiar learning method for the participants and a standard education delivery method in the project setting. The educational program was made available during the employee influenza vaccination campaign. Nurses in the intervention group (IHNV) had access to the educational program and were notified about the program through a flyer (Appendix C), which was distributed in both printed and digital format. Nurses at IHNV were also invited to participate in the program through an email announcement (Appendix D). Finally, the nursing leaders at the IHNV site were encouraged to include the availability of the educational program in their routine staff meeting agendas. Nurses in the comparison group (IHNE), who did not receive the educational program, were made aware of the study when they presented for vaccination or declination.
A four-question survey was used to collect data from two nonequivalent groups: (a) RNs at IHNV who received the intervention (web-based education) and (b) RNs working at IHNE, who did not. The use of a comparison group located in another hospital limited the risk of bias related to information sharing between nurses who participated in the education and their colleagues who may not have participated. As each RN presented to the IHNV or IHNE influenza vaccine clinic or occupational health office, he or she was provided the standard vaccine consent or declination form.
After vaccine administration or completion of the declination form, participants were asked to complete the study tool. The tool allowed participants to self-select whether or not they participated in the intervention and to indicate whether they opted to receive or decline the seasonal influenza vaccine. Other pertinent influenza and demographic information was also collected; however, anonymity was maintained. Surveys for data collection were returned immediately following completion to the secured lock box located at the site of vaccine administration.
Results: A total of 192 surveys were returned during the data collection period of approximately 3 weeks. During this time, both sites conducted “amnesty” days on which
Vaccine acceptance rates, overall, were similar between the two campuses. In fact, acceptance rates at IHNV (where the education was made available) were slightly lower (81.1%) than acceptance rates at IHN (84.2%; x2=0.318, p=0.573). However, vaccine acceptance rates among participants who reported completing the educational program were significantly higher (91.1%) than among those who reported not having viewed the education program (76.1%; x2=7.210, p=0.007). A significant difference in the vaccine acceptance rate was not seen in relation to any of the other demographic variables (nursing specialty, nursing role, academic degree). When comparing the prior year’s decision to vaccinate or not, a significant difference was seen in the percentage of RNs who chose vaccination this year. Specifically, 87% of RNs who received the vaccine the previous year were revaccinated this year, while only 12.4% of those who were previously vaccinated refused vaccination this year (x2=14.465, p<0.01). Only 11 RNs reported having had influenza in the previous 2 years; of those, 10 were vaccinated this year, and one was not.
Discussion:The current literature suggests that the most common reason for influenza vaccine refusal involves misconceptions regarding the safety and efficacy of the influenza vaccine. As such, the program was designed to address these misconceptions by providing factual information about influenza severity, vaccination safety, and historical efficacy. This information appears to have addressed the reasons previously unvaccinated RNs chose vaccination. In total, 39 RNs reported not having received the vaccine last year; of those, 11 completed the education and all but one chose to receive the vaccination this year. In addition, all of the individuals who previously had the flu and who participated in education accepted the vaccination this year.
The findings demonstrate that the educational program effectively addressed the most common barriers to vaccination in that individuals who participated in the educational program were vaccinated at a significantly higher rate than those who did not. Interestingly, the vaccination rates at the IHNE campus (comparison site) were slightly higher than the IHNV campus (intervention site). The findings suggest that the educational program influenced the individual’s vaccination choice; however, the impact on vaccine decision did not spread from these educated individuals to the overall hospital population One possible explanation is that individuals thoughtfully considered the program’s effectiveness and benefit to patients yet did not share or discuss their choice with others.
Conclusion: This project demonstrated a simple but tailored web-based educational program is effective in converting RNs to vaccination acceptance. Increased vaccination produces societal change by reducing nosocomial and community influenza transmission. Reduced influenza infection improves community health as well as patient safety. Future work should address community-wide HCW education initiatives and evaluate their impact on quality and financial indicators at the hospital and community levels.
