Objectives: To develop and validate a survey that can be used to measure key infection prevention and control (IP&C) structures and processes in LTC facilities. Methods: This study was designed using a three-phase methodology. In Phase I, six structural and process composite indices were developed based on the 2004 PHAC recommendations for IP&C in LTC and other literature. During the second phase of the study, a group of 7 experts in LTC IP&C used the Delphi methodology to validate and further develop the survey based on group consensus. Five Safety Principles published by the Institute of Medicine were also provided to the experts so they could be used to complement and further develop the concepts covered by the survey. The Delphi phase began in April and ended in October 2007; 114 worksheets were sent to experts to support the consensus-reaching process. Once the validity of a survey draft had been established based on expert-group consensus, it was pilot-tested in Phase III using 20 randomly selected LTC facilities in Fraser Health. Findings: The three-phase methodology used in this study was very useful and innovative way to further develop and validate the literature-based survey developed in Phase I for IP&C in long term care. In addition, by merging two bodies of knowledge and thought into the process, concepts and components that are not explicitly described in IP&C literature yet were felt to be key in program success, were incorporated into the measurement tool. Using Delphi, the experts expressed a need for IP&C professionals working in LTC to increase their knowledge, understanding and use of safety theory and strategies. They also felt that interdisciplinary work, the development of a culture of safety, and the development clear and simple IP&C systems are key ways in which infections can be prevented and outbreaks quickly controlled. In Phase III, the pilot-study analysis demonstrated the utility, validity and reliability of the survey. In addition, the analysis showed that there is a tendency for facilities to have lower levels of components within the Leadership Index and the ICP Index. / Medicine, Faculty of / Population and Public Health (SPPH), School of / Graduate

The objectives of this thesis are : 1) To provide a review of the literature on the significance, pathogenesis, diagnosis and management of secondary infections in the Intensive Care Unit. 2) To present the findings of a study of the technique of selective parenteral and enteral antisepsis regimen (SPEAR) in the patient population of the Respiratory ICU at Groote Schuur Hospital, aimed at reducing the incidence of secondary infection and, further to evaluate the study in terms of the effect of SPEAR on the incidence of secondary infection and its influence on the mortality due to secondary infection. 3) To present the findings of the effect of SPEAR on patient bacterial colonisation in the ICU, and to evaluate its longterm influence on the microbial flora of the ICU.

Master of Public Health - MPH / Hospital acquired infections are a huge public health concern, contributing to increased hospitalisation and death in developing countries. Infection prevention and control (IPC) is a discipline which relies on practical evidence-based approaches to preventing both patients and health workers from hospital avoidable infections. However, most of these infections, in many developing countries including Zimbabwe can be attributed to lack of compliance with infection prevention and control measures by health care workers. / 2023

INTRODUCTION: For persons with diabetes, surgery is fraught with complications; of primary concern is postoperative infection. A postoperative infection rate of up to 13% has been noted in patients with diabetes undergoing elective surgical procedures compared with less than 3% in nondiabetic populations. OBJECTIVE: The objective of this study was to provide preliminary evaluation of the efficacy of a novel bioresorbable microfilm matrix (20 µm thick) containing very low amounts of silver (0.16 mg/in²) in preventing surgical site infections when placed at the level of subcutaneous tissue and dermis prior to primary closure in the patient with diabetes undergoing elective surgery. MATERIALS AND METHODS: Twenty-two patients with diabetes undergoing nonemergent or elective foot or ankle surgery and who met at least 1 of the following 6 criteria were included in the study: neuropathy, infection, open wound, history of recurrent infection, nonhealing wound, or peripheral vascular disease. Patients underwent amputation, removal of exostosis, midfoot bone removal, Achilles tendon repair, bunionectomy, or an elevating osteotomy with primary closure of the wound. After hemostasis was obtained and subcutaneous closure achieved, if applicable, the bioresorbable microfilm matrix was applied just deep to the incision at the level of subcutaneous tissue and dermis, and the incision primarily closed. A nonadherent cover dressing was applied over the suture line, and routine follow-up was scheduled for 3 to 5 days later. RESULTS: No patient exhibited signs of infection at initial follow-up, and all adherent patients achieved complete healing during the 3-month follow-up period. Eighteen patients healed at a rate typical for the respective procedure. In 2 patients, time to healing was delayed secondary to weight-bearing dehiscence. Two patients were not included in the results secondary to multiple infractions of nonadherence with the postoperative protocol. CONCLUSIONS: The application of microfilm matrix in surgical incisions at the level of subcutaneous tissue and dermis prior to primary closure is safe for and has the potential to prevent postoperative surgical site infections in at-risk patients with diabetes..

Objectives: To assess in the undergraduate nursing course with active methodologies, the approach of the subject infections in Health Services; identify through the perspective of professors and students the approach of infections in Health Services and verify the teaching and learning methods that include this subject. Materials and Methods: A descriptive and exploratory, documentary and quanti-qualitative study held at the Undergraduate Nursing Course at the Pontifical Catholic University of São Paulo. The documentary research covered the Bank of Tutorials Problems and Material Support of the virtual environment. Participated in 12 (66.6%) teachers and 60 students (57.6%) who answered a questionnaire containing a Likert Scale and open questions. Results: The documentary study showed that the content is approached gradually, and meets the specificities of the axis of each year of graduation. The instruments are reliable, Cronbach's alpha value of 0.90 for professors and 0.91 for students. In characterizing the sample, teachers were 100% female. Students were 95% female and 5% male. 24 (40%) of the students are workers and eight (13.3%) perform paid internship. In the Structure dimension professors feel prepared to address the issue and do not provide material in the virtual environment. In Process they agreed that the practical activities allow the learning and there was no consensus for the approach of the subject as a learning objective in the study of problems. In Results they indicated that the student performs procedures applying the concepts. Students claimed that the structure of the materials used in practical activities are sufficient for learning and internship sites offer learning opportunities. In Process they agreed that the time spent on the subject is sufficient and had participated in activities addressing the subject. In the Result dimension they recognize that are applying the concepts in practice and claim that teaching activities developed in the course lead to the improvement of care quality. In comparing the three dimensions (analysis students instrument), the one that obtained the highest favorability score was Process (64%) and the worst, Structure (36%). Professors and students converged their views on the importance of the theme approach and suggest it to be further explored in the learning objectives and further deepening of the subject, respectively.

Healthcare personnel (HCP) frequently wear gloves when they care for patients in Standard Precautions to prevent contact with potentially infectious blood or body fluids. When HCP use gloves appropriately they reduce the risk of cross-contamination and decrease the risk of healthcare-associated infections (HAI). However, if HCP use gloves inappropriately they may inadvertently spread pathogens to patients and the patients’ environment. This study used a descriptive structured observational design to investigate three aspects of HCP glove use in a United States long-term care facility (LTCF). First, the PI examined the degree of inappropriate HCP glove use in a random sample of 76 HCP. Results indicate that the HCP used gloves inappropriately, failing to change gloves 66% of the time when a glove change was indicated. Over 44% of the HCP gloved touch points were defined as contaminated. Second, the PI examined the reliability of a new glove use tool (GUST). Results indicate the GUST is a reliable tool when used by trained observers documenting HCP glove use during toileting and perineal care events in LTCF, with intraclass correlation coefficients (ICC 2,1) over 0.75 for indicators of inappropriate glove use. Third, exploratory analysis indicated significant differences between inappropriate glove use in females and males. Female HCP had significantly more failed glove changes and contaminated touch points than male HCP in this study (p = 0.003). Future research studies should assess US HCP glove use to provide data needed for development of strategies to improve HCP glove use and reduce HAI.

Thesis (MPH.) --University of Limpopo, 2019. / Background: The purpose of this study was to investigate the extent of adherence to Infection Prevention and Control (IP&C) practices and programs amongst healthcare workers (HCWs) in the neonatal ward at Charlotte Maxeke Central Hospital (CMCH). Methods: Quantitative research was conducted on 57 Clinicians directly providing care to the patients and 5 Health Care Workers indirectly providing care to the patients by means of supporting the environment and logistics where patients are being taken care. Data collection was done using structured questionnaires. Because the population was so small, all available HCWs, who were willing to participate in the study were selected to participate in the study. Furthermore, the SAS statistical software was used to describe and analyse data received from the data collection tools. Results: Two groups of respondents participated in the study which were (n=57) who in the neonatal ward at CMCH and Health Care Workers (n=5), most of the clinicians were having 1 – 4 years’ experience working in the neonatal unit at 54.6% followed by 5 – 9 years at 21.8%. Participants were in the age group ≤ 30 years at 39.3% followed by 31 – 40 years (32.1%) and least being at ≥ 51 years (5.4%). Clinicians included 46% of professional nurses, 28.6% Auxiliary Nursing Assistant, 16.1% student nurses and 8.9% medical doctors. The findings revealed that there are some areas where there’s inconsistent in using gloves when anticipating exposure to blood or body fluids, drying of hands after washing and removing jewellery during clinical care among clinicians particularly doctors, professional nurses and student nurses about IPC practices during clinical care. In Conclusion: There was inadequate compliance with IPC standards and there’s a need for regular trainings to improve the knowledge about IPCs and awareness of its importance among clinicians and health care workers in the neonatal unit. The IPC committee need to be revitalized by the hospital management to be able to undertake its mandate. Furthermore, the Hospital administration should provide copies of IPPC policy Guidelines in all wards/units and ensure effective implementation through vi constant supervision and adequate supplies and conduct regular audits to enhance compliance and implementation of IPPC policy. The study concluded that there was inadequate compliance with IPC and there’s a need for regular trainings to improve the knowledge about IPCs and awareness of its importance among clinicians and health care workers in the neonatal unit.

As infecções de corrente sanguíneas relacionadas a cateter venoso central (ICS-CVC) são as causas mais freqüentes de morbidade e mortalidade em unidade de terapia intensiva (UTI). Muitos estudos mostram que educação e treinamento dos profissionais da área da saúde (PAS) sobre as práticas do cuidado com o CVC é uma importante ferramenta na prevenção e redução das ICS-CVC, entretanto o melhor modelo de educação ainda não está bem estabelecido. O objetivo desse estudo foi avaliar o impacto de dois modelos de intervenção educacional na redução das taxas de ICS-CVC, avaliar o conhecimento de boas práticas do cuidado com o CVC pelos profissionais da área da saúde (PAS) e avaliar a aderência às recomendações do cuidado com o CVC pelos PAS após aplicação dos diferentes modelos de intervenção. Realizou-se um estudo observacional, prospectivo, no período de Janeiro de 2005 a Junho de 2007 em duas unidades médicas de terapia intensiva (UTI A e UTI B) em um grande hospital escola (976 leitos sendo 120 leitos de UTI). O estudo foi dividido em três períodos: basal (somente as taxas de ICS-CVC e densidade de utilização do CVC foram avaliadas), diagnóstico (aplicação de questionário para avaliar o conhecimento dos PAS, seguido de observação das práticas realizado pelos PAS de cuidado durante a inserção, manipulação e curativo do CVC em ambas UTIs) e período de intervenção. Na UTI A, baseado nos problemas encontrados na observação, foram aplicadas aulas, dinâmicas, divulgação mensal das taxas de ICS-CVC, cartazes e etiquetas nos CVCs com lembretes sobre práticas de cuidado com esses dispositivos. Essa intervenção ocorreu para todos os PAS da unidade além de novos funcionários e residentes de medicina. Na UTI B uma única aula foi aplicada. Essa aula continha informações sobre cuidados durante a inserção, manipulação e curativo do CVC. Uma tabela foi criada e os dados foram armazenados no programa Epidata-2.1. Qui-quadrado foi calculado comparando o período de diagnóstico e de intervenção. Durante esses dois períodos, 940 e 843 CVCdias foram avaliados respectivamente na UTI A e 2175 e 1694 na UTI B. Questões sobre inserção CVC, desinfecção da conexão e curativo com solução alcoólica foi respondido corretamente por 70% a 100% dos PAS, entretanto a aderência as praticas de cuidados com o CVC durante a observação foi baixa, especialmente para a higiene das mãos (6%-35%) e desinfecção da conexão do CVC (45-68%). Após a intervenção das taxas de ICS-CVC caíram nas duas UTIs, entretanto na UTI A que ocorreu intervenção contínua, o decréscimo das taxas foi progressivo e sustentado. Na UTI B, onde uma única intervenção foi aplicada (aula) as taxas de ICS-CVC caíram inicialmente e voltaram a subir ao longo do tempo. Na UTI A, foram identificados 12 ICS-CVC por 1000 cateteresdias no período basal e nove meses após o início da intervenção contínua, não foi identificado nenhuma ICS-CVC. Na UTI B, 16,2 ICS por 1000 cateteres-dias no período basal caiu para 6,7 ICS por 1000 cateteres-dias. Em conclusão, programa educacional contínuo e personalizado parece desenvolver uma cultura de prevenção e é mais efetivo que uma única intervenção, com sustentação dos índices baixos de ICS-CVC / Central venous catheter-related bloodstream infections (CVC-BSI) are a frequent cause of morbidity and mortality in intensive care unit (ICU). Many studies have shown that education and training of health-care workers (HCW) on practices concerning CVCs are important tools to decrease and prevent CVC-BSI but the best educational model has yet to be established. The aim of this study was to evaluate the impact of two models of educational intervention on the rates of CVC-BSI in the intensive care units (ICUs), to evaluate the knowledge of HCWs regarding the recommendations of CVC care and to evaluate the adherence to practices concerning CVC for each ICU, comparing the preintervention and interventions periods. This prospective observational study was conducted from January 2005 to June 2007 in two medical intensive care units (ICU A and ICU B) in a large teaching hospital. The study was divided in 3 periods: Baseline (only CVC-BSI rates and DU were evaluated) Pre-intervention (questionnaire to evaluate the knowledge of HCWs and observation phase of CVC insertion, handling and dressing practices by the HCWs in both ICUs) and Intervention periods (in ICU A, the tailored and continuous intervention was started, in ICU B a single intervention lecture was given. A database was created using the program Epi info. Chi-square was calculated comparing the pre-intervention and intervention periods. During the pre-intervention and intervention periods 940 and 843 CVC-days were evaluated respectively in ICU A and 2175 and 1694 CVC-day in ICU B. Questions regarding CVC insertion, disinfection during manipulation and the use of an alcohol-based product during dressing were answered correctly by 70- 100% of the HCWs. Notwithstanding the compliance of HCWs to these practices in the pre-intervention period was low, especially to hand hygiene (6%-35%) and disinfection of hub (45-68%). After the intervention CVC-BSI rates declined in both units, however in the ICU in which continuous intervention was used, this decrease was progressive and sustained. In the ICU B in which a single lecture was given, the rates dropped initially and increased over time. In ICU A, 12 CVC-BSI per 1000 catheters-days in baseline period to zero after 9 months intervention. In ICU B 16.2 CVC-BSI per 1000 catheters -days in baseline period dropped to 6.7 CVC-BSI per 1000 catheters-day. In conclusion, personal customized continuous education seems to develop a culture of prevention and is more effective than single intervention, it leading to a sustained reduction of infection rates

O objetivo desta dissertação foi descrever a investigação de um surto de Klebsiella pneumoniae em uma unidade de terapia intensiva neonatal cujo elo entre os casos foi a mão, persistentemente colonizada pelo agente, de uma técnica de enfermagem que apresentava onicomicose em primeiro quirodáctilo esquerdo. Revisou-se a história da aplicação do método epidemiológico na investigação de surtos de infecção relacionada à assistência à saúde. Foi revisada também a literatura pertinente à investigação de surtos na busca de situações semelhantes. Embora seja bem conhecido o papel das mãos de profissional de saúde na transmissão cruzada de agentes causadores de infecção nosocomial, poucos surtos foram publicados em que estes profissionais atuaram como fonte comum e persistente de infecção. É mais freqüente Gram-positivos envolvidos, havendo cinco relatos de Gram-negativos neste contexto. A contribuição desta dissertação é alertar para o risco que profissionais de saúde com alterações tróficas em mãos e anexos podem representar quando atuam em unidades críticas de assistência, assim como durante investigações de surto em que a evidências apontam para uma fonte comum, a busca de profissional com tais alterações deve ser considerada / The aim of this study was to describe the investigation of an outbreak of Klebsiella pneumoniae at a neonatal intensive care unit, associated with the persistently colonized hands of a nurse who had onychomycosis on her left thumb. We reviewed the use of the epidemiological method for investigating healthcare related outbreaks of infections. We also reviewed the literature concerning the hands of health care personnel. Although the hands of healthcare workers (HCW) play a role in the cross-transmission of nosocomial pathogens, there are few reports in which the persistently colonized hands act as a common source perpetuating an outbreak. In this setting, Gram-positive outbreaks are frequently reported and five Gramnegative outbreaks were reported. By means of this work, we have sought to draw attention to the role of the healthcare professional with chronic lesions on the hand skin and/or fingernails. They may pose a risk of persistent transmission of nosocomial pathogens, especially for critical patients with invasive devices. During healthcare infection outbreaks, examination of the hands of HCW should be included in the investigation
