CHAPTER TWO: LITERATURE REVIEW
2.0 Introduction
This chapter reviews existing literature relevant to the study and its objectives. It is organized into three main sections: the level of compliance with infection control precautions among healthcare workers, institutional factors influencing compliance, and individual factors affecting adherence to infection control practices. The literature reviewed was obtained from various scholarly journals, including those focusing on infectious diseases, public health, nursing, and healthcare practice.
2.1 Level of Compliance with Infection Control Precautions among Health Workers
Numerous studies indicate that adherence to standard infection prevention precautions among healthcare workers remains below recommended levels. Despite the availability of established guidelines and awareness of the risks associated with non-compliance—such as exposure to blood-borne infections like hepatitis B, hepatitis C, and HIV—compliance is still inadequate. In many settings, adherence rates are reported to be below 50%, although slightly higher rates have been observed in some countries.
Hand hygiene is widely recognized as the most effective component of infection control, as hands are the primary mode of transmission for pathogens. However, global reports show that healthcare workers perform hand hygiene less frequently than recommended. To address this, the World Health Organization introduced the “Five Moments for Hand Hygiene” to guide healthcare workers on when to clean their hands during patient care.
In addition to hand hygiene, respiratory hygiene practices—such as covering the mouth when coughing or sneezing and proper disposal of tissues—are emphasized to reduce infection spread. Healthcare facilities are encouraged to provide adequate resources, including hand sanitizers, soap, and designated waiting areas for patients with respiratory symptoms.
Despite these guidelines, compliance with hand hygiene remains low across many healthcare settings, often ranging between 20% and 50%. Studies show variations across hospital units, with lower compliance in high-intensity areas like intensive care units and relatively higher rates in pediatric wards. Other infection control practices, such as the use of gloves, masks, and safe handling of sharps, also demonstrate inconsistent adherence.
Research further reveals that unsafe practices, including needle-stick injuries and improper waste disposal, are common, particularly in developing countries. While some healthcare workers demonstrate high compliance in specific practices, others, such as proper waste segregation and avoiding needle recapping, show significantly lower adherence rates.
Overall, findings consistently highlight that although awareness of infection control measures exists, actual practice remains suboptimal across different healthcare settings and professional groups.
2.2 Institutional Factors Associated with Compliance to Infection Control Precautions
Institutional or organizational factors play a significant role in influencing compliance with infection control guidelines. Challenges such as inadequate resources, lack of personal protective equipment (PPE), insufficient staffing, time constraints, and absence of clear protocols can hinder adherence.
Studies indicate that improving organizational systems—through standardization of procedures, provision of adequate supplies, and implementation of clinical audits—can enhance compliance. Access to infection prevention materials, continuous training, and supportive supervision are identified as key motivators for healthcare workers.
Conversely, barriers such as heavy workloads, lack of training, limited access to water and sanitation facilities, and poor management support contribute to non-compliance. Environmental constraints, including lack of infrastructure and insufficient monitoring systems, further complicate adherence.
Social and behavioral influences within healthcare settings also affect compliance. While peer influence may not always directly enforce adherence, positive role modeling and repeated demonstration of correct practices can gradually establish a culture of compliance among healthcare workers.
2.3 Individual Factors Associated with Compliance to Infection Control Precautions
Individual characteristics and perceptions significantly influence adherence to infection control practices. Factors such as knowledge, attitudes, beliefs, and risk perception determine whether healthcare workers follow recommended guidelines.
Some healthcare workers fail to comply due to misconceptions, such as underestimating infection risks, perceiving procedures as time-consuming, or experiencing discomfort from protective equipment. Skin irritation from handwashing agents, forgetfulness, and reliance on gloves as a substitute for hand hygiene are also commonly reported reasons for non-compliance.
Studies show that training and education improve compliance levels, as healthcare workers with adequate knowledge of infection prevention are more likely to adhere to guidelines. Additionally, demographic factors such as gender, professional cadre, and work experience have been associated with variations in compliance levels.
Other research highlights that healthcare workers with higher risk perception, better access to PPE, and strong institutional support are more likely to follow infection control precautions. However, gaps between knowledge and actual practice persist, indicating the need for continuous training and behavioral change interventions.
Furthermore, personality traits and behavioral tendencies, such as risk-taking attitudes, may negatively influence adherence. Occupational roles also play a part, with certain cadres—particularly nurses—being more exposed to risks such as needle-stick injuries due to the nature of their duties.
In summary, compliance with infection control precautions is influenced by a complex interplay of institutional and individual factors. Addressing these challenges requires a comprehensive approach that includes adequate resource provision, continuous training, supportive supervision, and promotion of a safety-oriented workplace culture.
