Abstract

Background: During the course of health care of patients, thousands of health care workers suffer occupational exposures among which nurses have high chances of exposure to blood-borne pathogens as they are the primary health care providers to patients in hospitals. Post-exposure prophylaxis has become routine following the occupational exposure of HCWs to HIV and HBV. So it is important that nurses keep their knowledge updated regarding handling of HIV and HBV patients and how to manage occupational exposure.
Method: A training programme for nurses was conducted by a tertiary care hospital and their knowledge regarding occupational exposure management and handling of HIV and HBV patients was assessed through pre-test and post-test questionnaire.
Result: Total 36 clinically registered nurses participated. The mean score of pre-test was 8.7 which increased to 10.1 in post-test. The knowledge related to PEP and handling of HIV and HBV patients improved significantly after the training class (p=0.0001 and 0.002 respectively).
Conclusion: The nurses are quite prone for occupational exposure to HIV and HBV and the findings of this study highlight the importance of continuous training of nurses so that they have a comprehensive understanding of PEP and standard precautions. Thorough orientation to the PEP procedure will help them access appropriate medical advice in a timely manner.

Introduction

Health care workers (HCWs) are constantly at risk of occupational exposure to blood borne pathogens especially HIV (Human immunodeficiency virus) and HBV (Hepatitis B virus) via needle stick injuries, percutaneous /mucosal/ non-intact skin contact with blood and body fluid [1]. 2.5% of HIV cases and 40% HBV and HCV (Hepatitis C virus) are due to occupational exposure among HCWs as reported by WHO [2]. The risk of transmission of HIV is 0.3%, after exposure to HIV-infected blood while it is much more (100 times) for HBV [3]. The prevalence of HBV and HIV in India is 2.4%-15.9%and 0-35% respectively [4,5]. As nurses are the frontline providers of healthcare, they represent the greatest proportion of exposed HCWs who take care of patients with HIV and HBV infection [6]. HCWs have a significant role in the prevention and management of HIV and HBV infected patients. There are many opportunities when HCWs, especially nurses, provide information to patients and their attendants regarding behavior changes that are required to prevent the spread of these infectious diseases. Therefore, it is essential that nurses should have adequate knowledge about Post Exposure Prophylaxis (PEP) and risk of transmission of HIV and HBV after occupational exposure to blood and body fluids. Thus training is an important interventional measure to protect them from professional exposure to HIV and HBV infections. Studies from other countries suggest that a lack of knowledge and negative attitudes among HCWs may serve as barriers to provide effective health education and disease management of these infectious diseases CDC recommends that nurses and all HCWs should follow universal precautions which are a set of important guidelines like use of Personal Protective Equipments (PPE)-gloves, masks, gowns etc. to protect patients and HCWs from exposure to blood borne pathogens [7]. In 1996, the healthcare infection control practices advisory committee (HICPAC) formulated certain revised guidelines, termed ‘standard precautions’, which included all major features of universal precautions and body substance isolation precautions to be taken for all patients at all times [8]. It is also important to assess the handling of HIV and HBV patients by the nurses. Various studies have shown that negative attitude and lack of knowledge among HCWs serves as a key barrier in the proper management of such patients [9,10]. In resource limited settings where the burden of HIV and HBV infections is huge, the data regarding occupational exposure and use of personal protective equipment’s (PPE) is limited. Many a times there PPE and safe devices are not available for use and proper sharp disposal methods are not followed. All these factors pose a high risk for the nurses working in such settings to occupational exposures. Few studies are available addressing the issues of occupational exposures and handling of HIV and HBV patients by nurses from developing countries. The present study was conducted with the aim of studying the existing knowledge of nurses about HIV and HBV patient care and effectiveness of a training programme as an intervention to improve patient care as well as reduce occupational exposure incidences.

Methods

Setting and participants

The study was conducted in a super speciality hospital which is a post graduate Institute at New Delhi after taking approval from the ethical and research committee of the Institute. A training programme was organized by the hospital specifically targeting the nurses working in tertiary care setting. The participants were clinical registered nurses working across various tertiary care hospitals in Delhi. Out of the total 36 clinically registered nurses who participated in the training programme, 23 were from same institute and 13 were from different institutes.

Study procedure, data collection and analysis

A self-administered pre–test questionnaire was developed. The questionnaire was used to test the knowledge related to handling of HIV and HBV patients and Post Exposure Prophylaxis (PEP) of HIV and HBV. All the participants answered the pre-test questionnaire. Their identity was kept anonymous. Then a training class was taken for all the nurses about handling of HIV and HBV patients and PEP against HIV and HBV, with the goal to increase their knowledge about HIV/HBV. The session included a power point presentation on standard precautions and PEP management of HIV and HBV, followed by discussion of case studies in small groups of 5-6 members each measuring their attitude as regards caring for individuals with HIV and HBV and management of occupational exposures. The session concluded with a knowledge contest (quiz). Participants were asked to share their experiences while caring for HIV and HBV patients. A post-test questionnaire was filled up by the participants. All questions in pre-test questionnaire were repeated in the post-test questionnaire. For questions related to PEP, the participants were supposed to choose the right answer and for questions related to handling of HIV and HBV patients, the participants had to agree or disagree. Improvement in knowledge was assessed by making a comparative analysis of the correct responses before and after the training class. For scoring, one mark was allotted to correct answer and zero to incorrect answer. Percentage of all correct answers before and after the training were calculated and compared. Statistical analysis was done by using the © 2018 Graphpad software, manufactured in San Diego, California. Fisher’s exact test was used to calculate significant P value (<0.05).

Results

A total of 36 nurses participated in the training programme. All of them answered the pre-test and post-test questionnaire. The mean score of pre-test was 8.7 which increased to 10.1 in post-test. Out of the 36, only 5 participants had experienced needle stick injury/ occupational exposure to blood and body fluids. Three of them had followed hand washing with soap and water immediately after exposure while one of them first reported to the concerned authorities while one of them irst took the patient for testing for HIV and HBV. Tables 1 and 2 depicted the comparative analysis of correct answers before and after training class. The knowledge related to PEP and handling of HIV and HBV patients improved significantly after the training class (p=0.0001 and 0.002 respectively).

Nurses’ awareness and knowledge regarding infectious body fluids and PEP (Table 1) significantly improved after the post test. They had become more aware about standard precautions and the importance of hand hygiene. Their knowledge on HIV infection and its transmission and HIV patient care improved significantly (Table 2).

Discussion

Nurses working in hospital settings encounter a lot of challenges in dealing with the HIV and HBV patients due to the high workload, staff shortage, lack of basic patient care items and PPE etc. Many a times they are also not vaccinated against HBV. In present study, we found that most of the nurses i.e. (60-70%) had knowledge about the standard precautions and PEP as detected by pre-test, which significantly improved after training to 85-90%. Regarding the participant’s knowledge about PEP, <50% had the knowledge about the ideal timing of starting of PEP and which body fluids are to be considered as potentially infectious. After the training class, this knowledge significantly improved and >80% nurses gave the correct answer (p=0.001) as to the ideal timing of starting PEP and what potentially infectious body fluids are (p=0.0006). This finding is concordant with another study done in China in 2016 [11] where before intervention 28% HCWs knew the ideal timing of starting PEP and which further increased to 50% after intervention while 70% who knew about infectious body fluids their knowledge increased to 80% after intervention. In another study in Bharatpur from India, 60% of the HCWs knew that the best time to start PEP is within 2 hours of occupational exposure [12].

Out of 36 participants, 5 nurses shared their experience of occupational exposure. Their exposure was mainly due to sharps or a needle stick injury. Three out of them had washed the site of exposure immediately with soap and water. Due to panic reaction, one out of them first reported the incident to the concerned authorities and the other took the patient’s sample first, for testing for HIV and HBV although both these nurses were aware of the first aid management after exposure. Most of the nurses (>70%) were aware of the fact that HBV vaccine is routinely available to HCWs and they all should be vaccinated in their hospital set up so they got themselves vaccinated. All the nurses were even aware of their antibody titres against HBV. All of them (100%) knew that the first step to minimize risk of infection after exposure is washing the site with soap and water. In contrast to present study, Dhital et al. [12] in their study found that only 39.39% of nurses had the knowledge of first aid management after getting needle stick injury. Surprisingly <50% knew that discarded needle, device/ instruments should not be tested for HIV/HBV after exposure. However, post-training the level of knowledge improved significantly (p=0.0031) as 80% had answered the questions correctly. More than 50% were aware that pregnancy is not a contraindication for PEP. They also knew the percentage transmission of HIV/HBV in needle stick injury and the correct method of sharp disposal.

There was significant improvement (p=0.0002) regarding the knowledge about handling of HIV/HBV infected patients. Their previous knowledge on hand hygiene was extremely good as 90% nurses knew that hand washing is the first priority in preventing infections. The nurses were well aware of standard precautions. All of them (100%) were aware of the fact that gloves should be changed between cares of different patients. The correct knowledge regarding route of transmission of HIV and HBV was 60% before training which significantly improved (p=0.0130) to 89%. The nurses became aware that HIV infected patients do not need isolation unless until they have some co-infection which may require isolation/transmission based precaution.

Since the burden of HIV/HBV infection in India is huge with increasing prevalence, nursing personnel are more prone to be at risk and lack of knowledge and training will further place the nurses at risk for occupational exposure. Therefore, regular interventions by conducting training programmes are essential for occupational safety. A study [13,14] showed that 62-88% of the needle stick injuries can be prevented through technology and training. In another study in Iran by Joukar et al., 52% of the HCW participants had unsatisfactory knowledge regarding HCV and HBV and they recommended that In service training about universal and standard precaution and also improvement in work condition can decrease the probable risk for health professional [15].

Updating the knowledge about standard precautions on a regular basis, safe injection practices, proper sharp disposal and PEP are effective measures in preventing occupational exposures among the nurses. Study done by Ishimaru et al. in Vietnam suggested that confidence in protecting oneself against infection was a positive factor associated with willingness to care for patients infected with HIV or HBV/HCV. A positive safety culture, such as strict infection control, not only protects healthcare workers but also improves the quality of patient care [16]. A well designed training programme implemented in this study included appropriate training content, lecture with group discussions, case studies to deal with different situations along with pre and post-test. A quiz contest in the end encouraged the nurses to recall all important facts about PEP and handling of HIV/HBV patients. Thus, present training session showed statistically significant improvement in the overall knowledge of nurses.

Conclusion

Understanding the attitude and knowledge of Nurses towards patients with HIV and HBV is the first step in improving health education and health care services. This study helps to develop interventions for HIV, HBV and HCV-related knowledge and attitudes for HCWs, which further will guide prevention strategies for HIV, HBV and HCV infection. It is recommended that more studies should be conducted at a larger scale, to assess the effectiveness of training interventions on occupational safety.
