ABSTRACT
Surgical aseptic technique is the application of those strict principles and procedures aimed at preventing the invasion of surgical sites by micro organisms. Prevention of surgical site infection (SSI) has become a priority worldwide. Approximately 50,000 deaths are estimated to occur annually across Europe, as a consequence of surgical site infection. In some university teaching hospitals in Nigeria, the rate of SSI ranges from 10 to 20%. This was linked to non compliance with standard practice due to poor theatre workers’ attitude to work. Compliance to surgical aseptic standard in this study entails theatre workers’ readiness and obedience to carry out the correct procedure in the area of surgical hand scrub, proper use of personal protective device and maintenance of sterile field during surgery. The purpose of this study is to determine the attitude and compliance of theatre workers towards the practice of surgical aseptic standard in tertiary health institutions in Enugu state. The specific objectives were to: (i) elicit theatre workers’ attitude towards various aspects of surgical aseptic standard, (ii) determine theatre workers’ practice of surgical aseptic standard, (iii) determine the relation between attitude and compliance in the practice of surgical aseptic standard and (iv)compare the practice of standard aseptic technique across tertiary health institution in Enugu State. The study adopted a descriptive cross sectional survey design. It was conducted at the three tertiary health institutions in Enugu State, Nigeria. Using purposive sampling technique and observing the following inclusion criteria: (a) participants must be doctors and nurses working in the operating theatre, (b) must be certified, registered, and licensed to practice in the operating theatre, (c) must be physically fit to operate or assist during surgery and (d) willingness to participate in the study. A total of 272 theatre workers were recruited from the population of 660 theatre worker. Instruments for data collection were the pre tested, 20 item researcher developed questionnaire on attitude of theatre workers and 40 item observational checklist. The instruments were validated by the researcher’s supervisor and two experts in the Department of Nursing in University of Nigeria Enugu Campus. Reliability of the questionnaire was established using test retest method at two weeks interval that yielded Cronbach’s alpha correlation coefficient of 0.88. The observational checklist, inter rater scores showed high degree of agreement. Data collected were subjected to descriptive statistics and analysed using Pearson’s Product Moment Correlation and analysis of variance (ANOVA) at p < 0.05 significant level. The significant means decision point for attitudinal item is >2.5 and >2 for observational checklist. The perceived attitude of theatre workers to surgical aseptic technique was positive with overall mean of 3.40 ± 0.81, while SHS had 3.79 ± 0.18, use of PPD 3.1 ± 0.18, and MSF had 3.43 ± 0.81.Theatre workers’ compliance to surgical standard practices were as follows: surgeons and peri operative nurses consistently had higher mean score, for SHS (2.89 ± 0.19, 2.78 ± 0.18), use of PPD (2.84 ± 0.12, 2.81 ± 0.22) and MSF(2.75 ± 0.20, 2.84 ± 0.19) respectively, than physician and nurse anesthetists score SHS (2.34 ± 0.45, 2.39 ± 0.40), use of PPD (2.43 ± 0.35, 2.71 ± 0.31) and MSF (2.29 ± 0.42, 2.61 ± 0.41) respectively. There were significant relationship (r= 0.86, r= 0.81, r= 083) between attitude and compliance. There were no significant variations (p> 0.05) in the practices across the three health institutions. Surgeon and physician anesthetists showed less compliance to the practice of wearing theatre outfit within the restricted area, with mean score of 1.67 and 1.56 respectively.
CHAPTER ONE
INTRODUCTION
Background to the Study
Surgical aseptic technique is the application of those strict principles, practices, and procedures aimed at preventing the invasion of surgical sites by microorganisms during intra and post-operative period (Briggs, 2013). This according to Albany, (2010) is achieved by ensuring that only uncontaminated equipment, fluid, and items come in contact with the sterile field during clinical procedures. Albany, (2010) refers to this procedure as Aseptic Non Touch Technique (ANTT). However, ineffective application of these clinical procedures and protocols according to Briggs, (2013) usually result to surgical site infection which in turn gives rise to long periods of hospitalization and high cost of hospital bill to both patient and hospital
The prevention of surgical site infection has become a priority worldwide. Approximately 50,000 deaths are estimated to occur annually across Europe as a consequence of surgical site infection (Jones, 2012). In New York, the national infection average per 1000 is 2.7% (National Infection Control, 2010). Albany (2010) in a study in a New York hospital recorded 3.7% infection rate per 1000 in the surgical intensive care unit. If the infection rate is that high in developed economies, the situation may be expected to be worse in developing countries like Nigeria, where challenges to compliance to surgical aseptic standards are definitely more.(Infection Control Policy (2010) A descriptive study carried out in the University Hospital Lagos by Afolabi, (2012) showed about 15% to 20% infection rate in male surgical ward. This was linked to non- compliance due to poor attitude of theatre workers to surgical aseptic standard in the area of surgical hand scrub, use of personal protective device and maintenance of sterile field during surgery observed by Berkeley (20012).
Compliance in this regard implies the readiness of theatre workers to practice various aspects of surgical aseptic standard in the area of surgical hand scrub, use of personal protective device and maintenance of surgical field during surgery. In other word, it involves willingness of theatre workers to stick firmly in practice to the rules and principles of standard aseptic technique. Previous studies according to Ginasekara (2010) have shown that compliance to the surgical aseptic standard among theatre workers has been generally unstable and increase in compliance has been difficult to sustain. Nevertheless, He noted that poor attitude is responsible for substandard practice as far as compliance to the surgical aseptic practice is concerned. Several reasons for noncompliance have been identified, including staff attitude and lack of interest to work. Relationship among theatre users has also been identified as an important factor in improving compliance (WHO, 2013). Sidon (2011) also stated that the designing and establishment of a practicable evidence-based surgical aseptic standard coupled with a positive attitude to work has been known to improve compliance to surgical aseptic standard practice.
Macleod, (2010) defines attitude as a predisposition, a tendency or a propensity to respond positively or negatively to a certain idea, object, person or situation. Attitude is therefore a serious variable in compliance (Leon, 2011).This is precisely because attitude influences individual’s choice of action either positively or negatively. A positive attitude is sure to affect compliance positively with a low rate of surgical site infection as collateral, while poor attitude is associated with noncompliance to the protocol and corresponding increase of rate of surgical site infection.
Despite application of the standard aseptic technique in recent times as required by WHO (2013) coupled with National and International recommendations for good practice in infection prevention and control in many health institutions, compliance has been low leading to surgical site infection. Surgical site infection has remained the third most common hospital acquired infection responsible for longer hospitalization with increased cost for both the patient and hospital (Briggs, 2013).
This study therefore wishes to assess theatre workers’ attitude and compliance towards various aspects of surgical aseptic standard as practice in the three Tertiary Health Institutions in Enugu State.
