Hand hygiene is the most important component to reducing the spread of infection and is known in healthcare as one of the basic necessities.1, 2 The current recommendation for hand hygiene is to wash hands with soap and water when visibly soiled, to use an anti-germicidal hand sanitizer or soap and water before and after all patient contact – before and after removing gloves – and after having contact with a known contaminant.2
When utilizing an alcohol-based hand sanitizer, the product should be placed onto the hands directly and hands should be rubbed together; all surfaces should be covered, and hands should be rubbed until the hands feel dry. The entire process should take approximately 20 seconds.3 Washing hands with soap and water requires the individual to initially wet the hands with water, then apply the soap to the hands.

Next, rub the hands together for at least 15 seconds ensuring all surfaces are covered including under the nails. The soap is rinsed off, hands are dried with a disposable towel, and the water is turned off with a towel.3 The compliance of healthcare workers washing their hands continues to be a problem in and out of the healthcare system.2 The overall average compliance rate of hand hygiene is 40%.2 Appropriate hand hygiene can decrease the spread of transmissible disease and decrease mortality.
Significance of the Problem
Prehospital providers, regardless of the situation, do not excel in hand hygiene.1 First responders, emergency medical technicians (EMTs), and paramedics work in unique environments such as homes, workplaces, and in the community. While entering these environments, emergency service personnel are in close contact with patients and increase the transmission risk of healthcare associated infections (HCAI) to the patient or hospital setting.1 Hand hygiene is of utmost importance in order to reduce disease transmission. However, there are gaps in compliance, access to equipment, and education.2 In a recent study (n=53) completed in an urban Minnesota region, only 62.8% of paramedics sanitized their hands after patient contact. Only 1.1% sanitized their hands prior to patient contact. Gloves were not worn 12.4% of the time while paramedics were caring for patients. Lastly, hand hygiene only occurred 19% of the time prior to eating and only 59.5% after eating a meal.2
The World Health Organization (WHO) reports that insufficient use of standard precautions puts individuals at risk for infections in healthcare settings. Therefore, healthcare professionals who do not use proper hand hygiene, or only use gloves, potentially increase the spread of infection. Healthcare associated infections (HCAI) can be caused by EMS personnel who do not use proper hand hygiene or those who lack education regarding appropriate hand hygiene. It is estimated at any point in time, 1.4 million individuals worldwide are affected by HCAI.4
HCAI can cause an increase in the length of hospital stays for patients, cause an increase in the number of resistant microorganisms such as methyl-resistant Staphylococcus aureus, increase the cost of healthcare, and increase patient mortality.4 These factors can be significant to both the health system as well as patients.5 All individuals receiving inpatient treatment at hospitals are at risk for HCAI.5 Therefore, any patient transported by EMS will have an increased risk for a HCAI. The goal of this education program was to create a practice improvement project which could be continued for years to come within the EMS community.
Purpose of This Project
The primary goal and purpose of this project was to create and implement a creative and interactive education program related to hand hygiene and infection prevention by targeting individuals working in a prehospital setting and EMS. B-EMS providers need to have continuous education at various points in their careers regarding the importance of the material as well as education of appropriate times for hand hygiene.2 Additionally, it is important to educate B-EMS providers regarding other vectors in which infections can be transmitted.
For instance, placing a mask on individuals with respiratory symptoms, such as a cough – especially if a fever is present – can help to reduce the transmission of infection.6 Additionally, proper hand hygiene after coughing or sneezing, or tissue use in addition to disposing tissues after use, can help to reduce the spread of transmissible infections.6
The PICOT question formulated for this DNP Project was: In basic emergency medical service providers (B-EMS providers) (P), does a formal education program focused on hand hygiene and infection prevention (I) affect knowledge, feelings of competence, and intent to use hand hygiene and infection prevention practices (O) at the completion of the education program (T)? One group enrolled in this project completed the post-tests immediately after the education program (Group 1); the remaining group completed the post-tests one month after the education (Group 2).
The sample was emergency medical responders (EMRs), fire fighters and emergency medical technicians providing EMS in a prehospital setting. For the purpose of this project, the term basic-emergency medical service provider (B-EMS) was used to define EMRs and EMTs. These individuals had already obtained or were working on obtaining their EMT certification or EMR. A non-randomized convenience sample was used to obtain participants for the sample population.
The project used a pre- and post-test design to examine whether a formal education program changed knowledge, feelings of competency and intent to use hand hygiene and infection prevention practices in B-EMS providers. In addition to a pre- and post-test participants completed a Likert Survey related to hand hygiene and infection prevention practices (HH-IPP) along with a demographic survey.
The HH-IPP was developed to determine participant’s feelings of competence and their intent to use hand hygiene and infection prevention practices at the completion of the education program. Ready-made tools offered through the WHO were used to provide education, lasting approximately one hour, with an emphasis on hand hygiene with regards to basic hand hygiene facts, appropriate times to perform hand hygiene, the type of hand hygiene that is necessary, glove usage including properly donning and doffing gloves, identification and discussion of antimicrobial resistance organisms, and discussion of appropriate mask usage.7
A slide presentation was adapted from the WHO ready-made tools. Next, an interactive learning portion of the hand hygiene and infection prevention formal education program occurred using GloGerm© lotion. GloGerm© is visible under a black light and allowed participants to identify the quality of hand washing that occurred.8
Statistical experts were consulted after data collection for the completion of the statistical analysis. A paired t-test was used to complete the statistical analysis of the two participant groups; the one month follow up group in addition to the group that took their post-test immediately after receiving the formal education. The paired t-test, which was a comparison of the pre- and post-test scores of each participant, was utilized to analyze both the pre- and post-test scores.
Reliability testing can determine if similar results would be produced with similar conditions, but was not completed on the individual pre- and post-test questions due to a small sample size. An analysis of covariance (ANCOVA) statistical analysis was completed to analyze the HH-IIP pre-and post-total scores.
Group 1 completed the written exam immediately after completing the formal education program while Group 2 completed the written exam at a one-month follow-up session. The pre- and post HH-IPP surveys were all completed immediately after receiving the formal education regarding hand hygiene and infection prevention. A matched pair t-test was used to determine if there was a statistically significant change in mean test scores (for the written exam) after the formal education program. The significance level was set at p < 0.05. An ANCOVA statistical model was utilized to analyze the pre-and post HH-IPP survey results.
Both groups (Group 1 and Group 2) had statistically significant increased mean scores on both the written exam test scores as well as the survey after receiving formal education about hand hygiene and infection prevention specific to EMS (p < .000). Therefore, the education program was effective in affecting knowledge, feelings of competence, and intent to use hand hygiene and infection prevention practices.
EMS personnel have some of the lowest compliance rates with hand hygiene due to limited access to running water, often eating in the same environment in which they work, working in chaotic situations, and the high demands of the job.9, 1, 10 Wearing and changing gloves is another important component to decreasing the transmission of communicable diseases. The failure of EMS personnel to change gloves at appropriate times, to wear gloves, or not use hand hygiene techniques after doffing gloves can increase the incidence of disease transmission.9, 10, 11
In a recent study with EMS workers (n= 1,494), gloves were only worn an average of 4.4% of the time for every patient encounter.1 Gloves are also put on too early and taken off too late.12, 11 This causes cross-contamination risks which were present 36.8% of the time when gloves were worn.12 Additionally, EMS personnel transmitted infections through cross-contamination even when gloves were utilized.12, 11 Although there is limited or no education, EMS personnel who have received formal education have an increased compliance and understanding of appropriate hand hygiene.10, 12 Limited access to products may also be a barrier to completing appropriate hand hygiene.9, 1, 13, 10
Alcohol based hand rubs have become the gold standard in healthcare;4 however, a barrier to some alcohol-based hand rubs is the inability to be effective against some sporous agents such as Clostridium difficile (C. difficile).4 All prehospital care providers who were provided with personalized hand sanitizer had increased use of reported hand hygiene.1 Therefore, if individuals had hand sanitizers in emergency response bags and on themselves, they may have an increased use of reported hand hygiene.
HCAI continue to be a growing concern within healthcare systems and for patients globally.9, 1, 11, 14 Through a proper understanding of handwashing and utilization of alcohol hand rubs, HCAI can be minimized.9 Hand hygiene continues to be the number one way at preventing and transmitting infections to others.1, 2
The results of this project support the implementation of a formal education program related to hand hygiene and infection prevention in B-EMS providers to increase knowledge, feelings of competence, and likelihood to use hand hygiene and infection prevention measures. Standardization of hand hygiene and infection prevention education for B-EMS providers could help to improve the quality of care to patients which therefore would help to decrease the transmission of disease.
