Background: Despite frequent recommendations from the World Health Organization (WHO), hand hygiene compliance (HHC) is an ongoing challenge among health care workers (HCWs). Objectives: This study aimed to evaluate the HHC in Iranian nurses and midwives during the COVID-19 pandemic. Methods: This observational study was conducted on 200 nurses and midwives working in two hospitals in Jiroft, Iran in 2021. Data were collected using a demographic information checklist and the WHO Hand Hygiene Observation Form. Data analysis was performed using the MannWhitney U, Chi-square, Kruskal-Wallis, and Spearman correlation coefficient tests. Results: The average percentage of HHC in the nurses and midwives was 51.3%. HHC before touching the patient and before doing a clean/aseptic procedure was at the lowest rate (33.5% and 49%, respectively) but was at the highest rate (81.8%) after a body fluid exposure risk. Conclusions: The HHC rates were low among nurses and midwives during the COVID-19 pandemic. It is essential to implement interventions to promote HHC in HCWs, especially in pandemic conditions.

The hands of health care providers are the most common route of pathogen transmission.[1] Hand hygiene is therefore accepted worldwide as an essential principle in the prevention of COVID-19.[2] COVID-19 first started in December 2019 in Wuhan, China, and quickly spread to other countries.[3] With the outbreak of the disease, the Centre for Disease Control (CDC) warned that COVID-19 spreads through direct and indirect contact with contaminated droplets. It was also announced that wearing a mask, keeping a social distance of at least two meters, and washing the hands frequently with soap and water for at least 20 s are the most effective ways to prevent virus transmission.[4]
Since the mid-eighteenth century, hand washing has been considered a necessary medical standard before performing any procedure. Then, in the early 19th century, hand hygiene was introduced as a universal standard.[5] Hand hygiene is the simplest and most cost-effective measure to prevent and control nosocomial infections[1],[6] and can reduce the risk of the COVID-19 outbreak by 24%31%.[2] Many studies have demonstrated the relationship between infection control, patient and staff safety, and hand hygiene.[5],[6],[7],[8] Thus, the World Health Organization (WHO) and studies conducted in this field have recommended various strategies to promote hand hygiene among health care professionals.[7],[9] Despite the WHO's recommendations, health care workers (HCWs) have poor compliance with hand hygiene protocols.[10] Hand hygiene compliance (HHC) rates among HCWs are estimated at 20%-40%.[11] Although some studies have examined hand hygiene among HCWs, none have examined hand hygiene among nurses and midwives in Iran during the COVID-19 pandemic. Investigating the extent of HHC provides a basis for identifying areas of weakness, providing feedback to HCWs, and developing effective interventions to promote hand hygiene in healthcare settings.[12]
Objectives
This study aimed to assess HHC among nurses and midwives working in the teaching hospitals of Jiroft University of Medical Sciences in 2021.
MethodsStudy setting and participants
A cross-sectional study was conducted on all midwives and nurses working in two teaching hospitals of Jiroft University of Medical Sciences in southern Iran. The data were collected from May to July 2021. Participants were recruited using a convenience sampling. Inclusion criteria were working in hospital wards, at least six months of work experience, and direct involvement in patient care. Nurses and midwives who were informed of the covert observation and those working in the COVID-19 wards were excluded from the study. The sample size was determined using the data provided by Seyed Nematian et al.,[13] where 39% of nurses complied with the hand hygiene protocol. Accordingly, using the formula for calculating the proportion in a limited population [Figure 1], with a Type I error of 0.05, d = 0.05, P = 0.39, and given that a total of 350 nurses and midwives were available, the sample size was estimated at 200 (130 nurses and 70 midwives).
Data collection instruments
Data were collected using a demographic information checklist and the WHO Hand Hygiene Observation Form.[14] The demographic information checklist assesses the participants' age, work experience, gender, marital status, and education level. This checklist was completed using the data available in the nursing offices of each hospital. The WHO Hand Hygiene Observation Form assesses hand hygiene at five mandatory moments, namely, before touching a patient, before a clean/aseptic procedure, after a body fluid exposure risk, after touching a patient, and after touching patient surroundings.[14] The percentage of HHC is calculated by dividing the number of acceptable health care actions performed by the total number of hand hygiene opportunities ×100.[15] The hand hygiene observation form has been used in many earlier studies.[1],[13],[15],[16],[17] We used inter-rater reliability[18] to examine the reliability of the hand hygiene form. For this purpose, two observers were asked to complete the hand hygiene form in a pilot study. Then, the percentage of agreement between the raters was calculated at 90%. Disagreements were then resolved by negotiation.
Data collection
The senior researcher selected two volunteer observers with master's degrees among the supervisors (one observer in each hospital) and instructed them to use the hand hygiene observation form to evaluate HHC. To start data collection, the hospital wards were first selected by lottery (i.e. Emergency Department, Intensive Care Unit, Inpatient, Surgical, Midwifery, and Maternity Care Units). The observers attended the selected wards on morning and evening shifts upon the full observance of health protocols. They identified eligible nurses and midwives and assessed their HHC via direct but covert observations during the care activities. The observations were made following the WHO's recommendations and the protocols used in previous studies.[13],[14],[16] The average time to complete each checklist was about 20 min.
Ethical considerations
The study protocol was approved by the ethics committee of Jiroft University of Medical Sciences under the code IR.JMU.REC.1400.003. We also sought permission from the hospital officials and the infection control departments. The observers were instructed about the confidentiality and anonymity of the participants' data, and each questionnaire was only identified with a unique code. As this study posed no risk to the participants, compliance with the hand hygiene protocol was assessed through direct but covert observations. To avoid the Hawthorne effect, we also conducted the observations without participant consent. All steps were performed in accordance with the relevant guidelines of the Helsinki Declaration.
Statistical analysis
Continuous variables were reported using mean and standard deviation, and the categorical variables were reported using frequency and percentage. Normality of the quantitative variables (i.e. HHC, age, and work experience) was rejected by the Kolmogorov–Smirnov test (P < 0.001). Therefore, the quantitative variables of the two groups were compared using the Mann–Whitney U and the Kruskal-Wallis tests. The Chi-square test was used to compare the subgroups in terms of categorical variables. P < 0.05 was considered statistically significant and the data were analyzed by SPSS software (IBM, Armonk, New York, version 16).
ResultsThe age range of the participants was 24-52 years. A total of 109 and 91 participants were observed in the morning and evening shifts, respectively. [Table 1] shows other demographic characteristics. Due to the nature of their work, nurses and midwives worked in different wards and also differed in terms of gender (P < 0.05). However, no statistically significant difference was found between the two groups for other personal characteristics (P > 0.05) [Table 1]. The average percentage of HHC was 51.3%.
[Table 2] presents hand hygiene opportunities and attempts and shows that HHC rates did not differ significantly between nurses and midwives in terms of gender, education, marital status, work shifts, hospital ward, and work experience (P > 0.05) [Table 2]. HHC rates differed significantly between the different situations. The lowest HHC rates were observed before touching a patient and before doing a clean/aseptic procedure (33.5% and 49%, respectively) whereas the highest rate (81.8%) was observed after a body fluid exposure risk [Table 3]. The post hoc dunn's test showed that the differences in HHC were significant only at two moments, i.e. before touching a patient and before a clean/aseptic procedure [Table 4].
Table 2: The descriptive statistics for hand hygiene compliance in the two groupsTable 3: The average hand hygiene compliance rate in different situation of hand hygieneTable 4: Multiple comparison of hand hygiene adherence rates in different situations DiscussionThe results of this study showed that about half of our participants were compliant with the hand hygiene protocol. This rate is low especially during the COVID-19 pandemic, however, the HHC rate in this study was higher than those in studies conducted before the COVID-19 pandemic in Isfahan (12.8%)[19] and northeast Iran (43%).[20] Nonetheless, the HHC rate in our study was similar to a study conducted in the United States (US) where the HHC rate was estimated using automated hand hygiene monitoring systems installed in 90 hospitals. The HHC rate was 46% before the pandemic and rose to 60% immediately after the pandemic. However, it gradually declined, reaching 54% four weeks after the pandemic.[12] Our findings also differed from the results of a recent study in China where the HHC in a pediatric ward increased from 83% to 100% after an audit and training program was implemented in another ward.[21] The reasons for the low HHC rate in our study were possibly the increased workload of the HCWs during the COVID-19 pandemic, lack of knowledge,[1] inefficiency of infection control programs implemented in the hospitals, and lack of adequate supervision and feedback.[22] In addition, nurses' desire to reduce contact time with patients during the COVID-19 pandemic could negatively affect their HHC.
Our results indicated that HHC was at the lowest rates before touching the patient and before a clean/aseptic procedure. This finding shows that self-protection is the main motive for hand hygiene in HCWs.[23],[24],[25] It appears that our participants prioritized self-protection over patient safety. Although self-protectionis is critical, the WHO highlights the critical role of nurses and midwives in saving millions of lives,[21],[26] especially in the fight against COVID-19. Thus, officials in the healthcare system need to take effective measures to improve the education, awareness, and motivation of HCWs to comply with hand hygiene, especially before touching patients. The current study showed no significant differences in HHC rates by gender, education, work experience, ward type, and shift. Another study in Iran also showed that education and work experience did not predict HHC.[13] Contrarily, a study in the US showed that emergency room nurses had lower HHC than other nurses.[27] A study in Saudi Arabia also showed that nurses with more experience and higher education had higher HHC rates.[15] The conflicting results can be attributed to differences in clinical settings, organizational guidelines, and how and when data were collected.
This study was a cross-sectional study. Thus, longitudinal studies should be performed to investigate the impact of the epidemic on the HHC of medical staff's, especially those working night shifts. Moreover, to prevent the participants' awareness of direct observation, it was not possible to closely monitor them. Thus, observers may have not noticed instances such as contamination of the participants' hands when performing procedures. However, assessing hand hygiene through direct but covert observation was the main strength of this study.
ConclusionThis study showed that the HHC rates among nurses and midwives were low, especially before touching patients and before doing a clean/aseptic procedure. It is suggested to design hand hygiene promotion interventions for nurses and midwives to prevent the transmission of the disease to them and to create a safe environment for patients, especially during the COVID-19 pandemic. Regular and frequent auditing and feedback on the hand hygiene practices of nurses, midwives, and other HCWs are recommended to promote hand hygiene practices in hospitals.
