Surgical site infection not only brings morbidity and mortality to patients, but it also bring substantial financial burden to the hospital and the healthcare system. To minimize the clinical consequences of surgical site infection, it is crucial that all appropriate measures for reduction of surgical site infection should be implemented. Since patient’s skin is a potential source of pathogens, normal skin flora is a common cause of surgical site infections. Preoperative skin disinfection of the surgical site with an antiseptic agent is an effective method to remove the soil and transient organisms from the skin. Currently, there are different skin antiseptics available and the most commonly used agents are povidone iodine and chlorhexidine gluconate. Although povidone iodine has a long-standing recommendation and it is widely used in various surgical procedures, it has several limitations. On the other hand, there is an increasing interest of the use of chlorhexidine in indwelling catheter placement and care, surgical hand scrubbing, as well as wound dressing. In view of this, there is a potential of replacing povidone iodine by chlorhexidine as preoperative skin antiseptic agent. As there is no existing guideline supportingthis innovative movement, this dissertation aimed to review the currently available evidence on preoperative skin preparation and to develop an evidence-based guideline of using chlorhexidine in preoperative skin preparation for reducing surgical site infection in patients undergoing general surgery. Five randomized controlled studies were identified from MEDLINE, CINAHL and PUBMED and evaluated by a critical appraisal tool, the Scottish Intercollegiate Guidelines Network. All studies reported that preoperative skin preparation with chlorhexidine is more effective than the use of povidone iodine in reducing surgical site infection. An evidence-based guideline is developed according to the guideline development process from the Scottish Intercollegiate Guideline Network. Patient characteristics, local clinical setting, organizational infrastructure and staff competency is congruent with the proposed innovation. The new protocol not only can minimize the risk of postoperative surgical site infection but also save costs. The cost-benefit analysis showed that the new protocol can help to save $675,552 to $1,097,772 (HK dollars) in six-month period after implementation. To facilitate a more comprehensive plan in actual implementation of the proposed guideline, stakeholders at administrative, managerial, and operational levels would be invited to take part in the 12-week pilot test. Surgical site infection, staff satisfaction and compliance, as well as cost and benefit ratio of the guideline would be measured in the evaluation plan. The refined guidelines would then be implemented for one year. The effectiveness of the guideline would be determined by reduction in postoperative surgical site infection, increase in staff knowledge and satisfaction, and the overall expenditure. / published_or_final_version / Nursing Studies / Master / Master of Nursing

Submitted in partial compliance with the requirements of the Master’s Degree in Technology: Homoeopathy, Department of Homeopathy, Durban University of Technology, Durban, South Africa, 2016. / Introduction This research study investigated the efficacy of a homoeopathic protocol in the post-surgical wound management of medical male circumcision (MMC) in the KwaZulu-Natal region. The study had 30 male participants from 10 of the 11 district municipalities of the KwaZulu-Natal province. The study consultations took place at the Durban University of Technology Health Sciences Clinic. Aim of the study The aim of the study was to determine the efficacy of a topical application of a homoeopathic protocol using; Calendula officinalis (mother tincture (M.T.)), Hypericum perforatum (M.T.) and Delphinum staphysagria 30CH (orally) as an adjunct to the standard care of the post-surgical effects of circumcision and to assess the wounds post-surgically in terms of time taken to heal and associated signs and symptoms. Methodology The data for this study was collected from 30 male participants who had undergone MMC from various hospitals within KwaZulu-Natal. The participants were aged between 18 to 30 years. All participants underwent a medical examination and were given a pain rating scale and a pain and sleep diary. They were instructed to keep a daily record using the data collection tools mentioned above for the study period of six weeks. Descriptive statistics were employed in the form of tables and graphs. The data analysis methods used in the study are: independent samples t-test and the non-parametric Spearman’s Correlation test. Results Group statistics in relation to ‘time to heal’ showed a statistically significant reduction in the time taken for the group on the homoeopathic protocol. Analysis of ‘time to heal’ by group shows that on average, Group 1 (active group: homoeopathic protocol + standard care) (M = 31.4, SD = 7.49) healed in a significantly shorter time than Group 2 (control group: standard care) (M = 38.6667, SD = 1.99), t (28) = -2.617, p=.014. There was no other statistical significance noted except for the results of the Spearman’s rho, where table 4.8 shows there is a significant positive correlation between average quality sleep until healing and the proportion of days across healing NOT feeling refreshed (rho = .676, p<.0005). / M

This research project investigated the impact of an action research intervention implemented to reducing surgical wound infection in one of the acute care hospitals in India. The study aimed to develop and implement a clinical practice improvement program in reducing surgical wound infection by improving the hand washing and wound dressing practices of nurses. The study also aimed to identify the important contributing factors to a model that predicts surgical wound infection. Pre-post evaluation measures were taken to compare the results of surgical wound infection rate before and after the implementation of the intervention. Surgical wounds of two thousand patients (one thousand before the intervention and another one thousand after) were assessed to determine the wound infection rate and severity of wound infection. The hand washing and wound dressing practices of forty nurses were observed. These same nurses were involved in the intervention using a participatory action research process. The results of the study suggest that there was a marked, significant reduction in the rate and severity of wound infection following the implementation of the intervention. By increasing the hand washing facilities in the ward, educating nurses on the importance of better hygiene, pre-operative shaving and post-operative wound care, the hand washing and wound dressing practices of nurses improved considerably. These improvements resulted in a reduction in the number and severity of patients' surgical wound infections. The study also examined the contribution of different factors to surgical wound infection in a Indian hospital. Significant predictive factors were the patients' age, longer pre-operative hospital stay, extended pre-operative shaving time before surgery, wound class, and co-morbidity of the patient. The identification of risk factors that contributed to increased surgical wound infection for example pre-operative skin preparation, pre-operative hospital stay of the patient would help in taking appropriate measures at the ward level and organisation as a whole. Nosocomial infections extends to an unnecessary lengthy hospital stay, additional treatment increased mortality and morbidity, and increased cost to the patients and the nation as a whole. This project proved that educational mentoring, data surveillance processes and involving the nurses in an action research process were effective in enabling participants to improve their clinical practice and thereby reduce the incidence of patients' surgical wound infections. Establishing infection control teams, ongoing surveillance and feedback to staff of nosocomial infection rates is an urgent need in all Indian hospitals. Organisational management, as a priority, need to provide funding and staff dedicated to undertaking this essential work. Health care professionals can no longer plead ignorance of a situation for which all have a moral and professional responsibility.
