Knowledge and Practice of Aseptic Techniques among Nurses

1.1 Introduction

Aseptic technique is defined as the set of clinical practices and procedures designed to prevent contamination by pathogens during medical and nursing care, thereby reducing the risk of healthcare-associated infections (HAIs) among patients and healthcare workers (World Health Organization, 2016). It involves strict adherence to infection prevention principles such as hand hygiene, use of sterile instruments, proper wound care, and maintenance of a sterile field during procedures (Centers for Disease Control and Prevention, 2019). In nursing practice, aseptic technique is a fundamental component of patient safety and quality care delivery because it minimizes the transmission of microorganisms within healthcare environments (Pittet et al., 2000).

In hospital settings such as Okwe General Hospital, Asaba, Delta State, nurses play a central role in implementing aseptic procedures during routine and emergency care. The effectiveness of these practices is highly dependent on the nurses' level of knowledge, continuous training, availability of materials, and adherence to infection prevention guidelines (World Health Organization, 2016).

As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are significance of the study, scope of work, research hypothesis and questions, limitation of the study and definition of terms.

1.2 Background of Study

Aseptic techniques evolved into structured infection prevention and control (IPC) guidelines that are now globally implemented in healthcare systems. According to the World Health Organization (WHO, 2016), aseptic technique is a fundamental infection prevention practice that involves a set of clinical procedures aimed at maintaining sterility and preventing the entry of pathogenic microorganisms into the body during clinical care. It includes hand hygiene, use of sterile gloves and instruments, proper cleaning and disinfection of equipment, and adherence to sterile field protocols during invasive procedures. WHO (2016) further reported that healthcare-associated infections (HAIs) remain one of the most significant challenges in global healthcare systems, particularly in low- and middle-income countries where compliance with infection prevention standards is often inconsistent.

CDC (2019) asserted that hand hygiene alone, when properly practiced, is the single most effective measure for preventing HAIs. However, lapses in compliance among healthcare workers, especially nurses who have continuous patient contact, continue to contribute to preventable infections in hospitals worldwide. Pittet et al. (2000) stated that even when healthcare workers are aware of infection control guidelines, actual adherence is often suboptimal due to workload pressure, inadequate staffing, and lack of continuous reinforcement of training. This indicates that knowledge alone does not always translate into effective practice in clinical environments.

Ogoina (2011) affirmed that these limitations contribute to inconsistent application of aseptic techniques, thereby increasing the risk of hospital-acquired infections among patients. In many tertiary and secondary healthcare institutions in Nigeria, the burden of HAIs remains high due to systemic weaknesses in infection prevention and control systems. According to Allegranzi and Pittet (2009), adherence to aseptic technique is strongly linked to institutional commitment to infection prevention programs, including the provision of adequate supplies such as alcohol-based hand rubs, sterile gloves, and disinfectants. They contended that without institutional support, even well-trained nurses may struggle to maintain consistent aseptic practices in busy clinical settings.

World Health Organization (2016) reported that structured infection prevention programs, regular audits, and feedback mechanisms significantly improve adherence rates among nurses and other healthcare professionals.

Loveday et al. (2014) stated that nursing practices such as wound dressing, catheter insertion, and medication administration require strict adherence to aseptic technique to prevent cross-contamination. However, variations in training quality and clinical supervision often lead to differences in practice standards among nurses across different healthcare facilities. According to Apisarnthanarak et al. (2015), gaps between knowledge and practice in infection control are common in healthcare settings, particularly in developing countries. They affirmed that despite awareness of aseptic procedures, many nurses fail to consistently apply them due to behavioral, environmental, and institutional barriers.

In the context of Okwe General Hospital, Asaba, Delta State, nurses are expected to implement aseptic techniques effectively as part of their daily clinical responsibilities. However, like many healthcare institutions in Nigeria, challenges such as limited resources, high patient load, and varying levels of professional training may affect adherence to standard infection prevention practices. On the other hand, the increasing rate of hospital-acquired infections in some healthcare facilities suggests that compliance with aseptic procedures may not be optimal, thereby raising concerns about the effectiveness of current practices.

This study is set against the backdrop of increasing global concern over healthcare-associated infections and the need to ensure that nurses consistently apply aseptic techniques in clinical practice to improve patient safety and healthcare outcomes.

1.3 Statement of Problems

Aseptic technique remains a critical aspect of nursing care, yet healthcare-associated infections continue to persist in many hospitals, particularly in developing regions where compliance with infection prevention standards is inconsistent (World Health Organization, 2016). Nurses at Okwe General Hospital, Asaba, Delta State are expected to maintain strict adherence to aseptic procedures during patient care to reduce infection risks; however, observed clinical outcomes suggest possible gaps between knowledge and actual practice of these techniques.

Furthermore, nurses demonstrate varying levels of understanding regarding aseptic procedures such as hand hygiene, sterilization of equipment, and maintenance of sterile fields during invasive procedures (Ogoina, 2011). On the other hand, even when knowledge of aseptic technique is present, adherence during routine clinical duties is often compromised due to time constraints and environmental limitations within hospital wards.

Furthermore, the persistence of hospital-acquired infections in healthcare facilities suggests that the expected standards of aseptic practice are not fully achieved, thereby posing significant risks to patient safety and recovery outcomes (CDC, 2019). It is against this backdrop that this study seeks to examine the knowledge and practice of aseptic techniques among nurses in Okwe General Hospital, Asaba, Delta State.

1.4 Aim and Objectives of Study

The aim of this study is to assess the knowledge and practice of aseptic techniques among nurses in Okwe General Hospital, Asaba, Delta State. In achieving this aim, the following specific objectives were laid out as follows:

1. To assess the level of knowledge of aseptic techniques among nurses.
2. To evaluate the practice of aseptic techniques among nurses during clinical procedures.
3. To identify factors affecting adherence to aseptic techniques among nurses.
4. To determine the relationship between knowledge and practice of aseptic techniques.
5. To examine the impact of aseptic practice on infection prevention in the hospital.
