Abstract.

Background. Hand hygiene is recognized as the leading measure to prevent cross-transmission of microorganisms. Regarding hospital acquired infections, the compliance of nurses with hand washing guidelines seems to be vital in preventing the disease transmission among patients. There is a paucity of studies exploring this subject in Asia. Especially medical and nursing student’s knowledge of standard hand hygiene precautions is rarely compared. Methods. A cross-sectional study was conducted among 98 medical and 46 nursing students in a tertiary medical college in India. Knowledge was assessed using WHO hand hygiene questionnaire. Attitude and practices were evaluated by using another self-structured questionnaire. test was used to compare the percentage of correct responses between medical and nursing students. A value less than 0.05 was considered significant. Results. Only 9% of participants (13 out of 144) had good knowledge regarding hand hygiene. Nursing students knowledge () , attitude (), and practices () were significantly better than medical students.

1. Introduction

Hand hygiene is recognized as the leading measure to prevent cross-transmission of microorganisms and to reduce the incidence of health care associated infections [1, 2]. Despite the relative simplicity of this procedure, compliance with hand hygiene among health care providers is as low as 40% [3–5]. To address this problem, continuous efforts are being made to identify effective and sustainable strategies. One of such efforts is the introduction of an evidence-based concept of “My five moments for hand hygiene” by World Health Organization. These five moments that call for the use of hand hygiene include the moment before touching a patient, before performing aseptic and clean procedures, after being at risk of exposure to body fluids, after touching a patient, and after touching patient surroundings. This concept has been aptly used to improve understanding, training, monitoring, and reporting hand hygiene among healthcare workers [6].

Nurses constitute the largest percentage of the health care workers (HCW) [7] and they are the “nucleus of the health care system” [8]. Because they spend more time with patients than any other HCWs, their compliance with hand washing guidelines seems to be more vital in preventing the disease transmission among patients.

In Asia there is a paucity of studies [7–10] exploring this subject, although the prevalence of health care associated infections is high in this region; especially medical and nursing student’s knowledge of standard precautions is rarely compared [11]. The observance of hygiene by students is reported as being weak [12, 13]. Therefore, it is absolutely essential to investigate and know nurse’s knowledge, attitudes, and practices about hand washing so that appropriate strategies can be developed to promote hand washing compliance.

2. Material and Method

This cross-sectional study was conducted in Navodaya Medical College (NMC), one of the biggest teaching hospitals in Raichur, India. This district is one of the 30 most backward places in India. NMC provides tertiary medical care for residents of Raichur and patients referred from neighboring states.

Ethical clearance was obtained from the Ethical Review Committee of Navodaya Medical College. Medical and nursing students were explained the content and nature of the study. Verbal consent was obtained from 98 medical and 46 nursing students who volunteered to participate. A self-administered questionnaire containing a set of questions regarding hand-hygiene knowledge, attitudes, and practices was distributed to all participants.

Knowledge was assessed using WHO’s hand hygiene questionnaire for health care workers. This proforma of 25 questions includes multiple choice and “yes” or “no” questions. Attitude and practice were assessed using another self-structured questionnaire which consists of 10 and 6 questions, respectively. Respondents were given the option to select on a 1- to 7-point scale between strongly agree and strongly disagree. A score of 0 was given for negative attitudes and puny practices. 1 point was given for each correct response to positive attitudes and good practices so that maximum score for attitude is 10 and for practice it is 6. A score of more than 75% was considered good, 50–74% moderate, and less than 50% was taken as poor. Data was analyzed using SPSS version software. Descriptive statistics was used to calculate percentages for each of the responses given. test was used to compare the percentage of correct responses between medical and nursing students. A value less than 0.05 was considered significant.

3. Results

There were a total of 144 study participants (46 nursing students and 98 medical students). In this a majority (79%, 114 out of 144) had claimed to have received formal training in hand washing. A significant difference was observed between medical (73 out of 98, (74.2%)) and nursing (44 out of 46, (95.4%)) students who had received formal training in hand hygiene. When asked about the correct technique of hand washing, 89 out of 98 medical students (91.3%) and 45 of 46 nursing students (97.8%) said they knew the correct technique of hand washing.

4. Knowledge on Hand Hygiene

The knowledge on hand hygiene was moderate (107 out of 144, 74%) among the total study population. Only 9% of participants (13 out of 144) had good knowledge regarding hand hygiene. Nursing students had significantly better knowledge than medical students. The percentages of correct responses of the two groups of students to the individual questions on hand hygiene knowledge are given in Table 1.

7. Discussion

In our study, both study groups had moderate knowledge on hand hygiene, which was a positive finding. Feather et al. [12] studied the hand hygiene practices of 187 candidates during final MBBS OSCE (Objective Structured Clinical Examination) at The Royal London Hospital School of Medicine and Dentistry in UK and found that only 8.5% of candidates washed their hands after patient contact, although the figure rose to 18.3% when hand hygiene signs were displayed. The situation in healthcare centers of developing countries is even more unacceptable [9]. In an earlier study from Saudi Arabia [14], adherence to hand hygiene was seen in 70% of medical students, 18.8% of nurses, and 9.1% of senior medical staff, but the technique was suboptimal in all. Like most previous studies, our study showed that the overall compliance of hand hygiene by HCWs was less than 50% [15]. However, compliance with hand hygiene practice differed among different professional categories of HCWs. Compliance among the physician category was low, compared to nursing groups. Van de Mortel et al. in 2010 [16] compared the hand hygiene knowledge, beliefs, and practices between nursing and medical students. They found that the nursing students hand hygiene knowledge was significantly higher than that of medical students which is consistent with our study.

Our study shows the importance of improving the current training programs targeting hand hygiene practices among medical and nursing students. Hand hygiene training sessions may need to be conducted more frequently for medical students with continuous monitoring and performance feedback to encourage them to follow correct hand hygiene practices.
