[Knowledge and practices of the steps prior to the sterilization of heat-resistant medical devices: Study at University Hospital Centre of Sahloul, Sousse-Tunisia - 2022]. / Connaissances et pratiques des étapes préalables à la stérilisation des dispositifs médicaux thermorésistants : étude au centre hospitalo-universitaire Sahloul, Sousse-Tunisie ­ 2022.

OBJECTIVES: The standard process of central sterilization is crucial for the optimal functioning of the operating room. The outcome of this process is closely linked to the steps preceding the steps prior to the sterilization step itself. These steps include pre-disinfection carried out in the operating rooms and other stages, namely washing, drying and packaging, which must be performed in the central sterilization unit. In this context, this study aimed to describe the knowledge of the staff in the operating rooms and the central sterilization unit at Sahloul University Hospital in Sousse (Tunisia) in 2022, regarding the steps prior to the sterilization of reusable thermoresistant medical devices and to describe their practices in terms of compliance with these steps. METHOD: A descriptive study was conducted from January 2022 to June 2022 with the aforementioned staff, using a self-administered questionnaire to assess their knowledge of the pre-sterilization steps and a direct observation audit of their practices with regard to these steps. Both measurement instruments were pre-tested. RESULTS: Out of 102 self-administered questionnaires (knowledge assessment) distributed to the staff concerned, only 80 were returned and correctly filled out, giving a response rate of 78.4%. Participants' responses regarding the order of steps prior to the sterilization were incorrect in 64% of cases. With regard to the evaluation of professional practices, 224 observations were made in the study area (practice audit). In 82% of these observations, the pre-disinfection step was confused with the washing step. The use of Betadine brushes and scrubbing pads for device washing was noted in 89.3%, along with the absence of swabbing of the canals and hollow parts in 9.4% of cases and the absence of drying of the canals with compressed air. CONCLUSION: Mastery of the steps prior to sterilisation of reusable thermoresistant medical devices was insufficient in our institution, suggesting the importance of reinforcing the implementation of the procedure through a continuous training program followed by action plans.

A retrospective analysis of adverse events reported by Tunisian intensive care units' professionals.

INTRODUCTION: Adverse events (AEs) that occur in hospitals remain a challenge worldwide, and especially in intensive care units (ICUs) where they are more likely to occur. Monitoring of AEs can provide insight into the status and advances of patient safety. This study aimed to examine the AEs reported during the 20 months after the implementation of the AE reporting system. METHODS: We conducted a retrospective analysis of a voluntary ICU AE reporting system. Incidents were reported by the staff from ten ICUs in the Sahloul University Hospital (Tunisia) between February 2020 and September 2021. RESULTS: A total of 265 reports were received, of which 61.9% were deemed preventable. The most frequently reported event was healthcare-associated infection (30.2%, n = 80), followed by pressure ulcers (18.5%, n = 49). At the time of reporting, 25 patients (9.4%) had died as a result of an AE and in 51.3% of cases, the event had resulted in an increased length of stay. Provider-related factors contributed to 64.2% of the events, whilst patient-related factors contributed to 53.6% of the events. As for criticality, 34.3% of the events (n = 91) were unacceptable (c3) and 36.3% of the events (n = 96) were 'acceptable under control' (c2). CONCLUSIONS: The reporting system provided rich information on the characteristics of reported AEs that occur in ICUs and their consequences and may be therefore useful for designing effective and evidence-based interventions to reduce the occurrence of AEs.

Educational effectiveness of simulation in teaching health science students Smoking cessation: A Systematic Review.

BACKGROUND: Simulation is one of the educational tools that can be used in the learning process to help with smoking cessation. AIM: To synthesize all the publications studying the contribution of simulation as an educational tool in the acquisition of skills to help with smoking cessation. METHODS: We performed a systematic review of the Francophone and Anglophone literature over the past 24 years (1997 to 2020) using the PubMed, Science Direct and Cochrane Library databases. RESULTS: A total of 14 articles were included. The most used methods were thestandardized patient, role play and video projection with discussion. The simulation hasnot only proved its effectiveness in terms of acquiring knowledge and self-confidencein the management of the smoking patient in the short term, but also in the acquisition of verbal and non-verbal skills in the long term. CONCLUSION: This review highlighted the interest of simulation as an educational tool to acquire skills to help with smoking cessation regardless of the method used.

[Therapeutic education in patients with coronary artery disease: impact on smoking cessation]. / Éducation thérapeutique chez les patients coronariens : impact sur le sevrage tabagique.

AIM OF THE STUDY: To describe the results of a therapeutic education program (cessation rate and success factors) among smoking coronary patients followed in the smoking cessation clinic at Sahloul University Hospital in Sousse during the period from 2015 to 2020. PATIENTS AND METHODS: A descriptive cross-sectional study was conducted among smokers with coronary artery disease who presented to the smoking cessation clinic at Sahloul University Hospital during the period from 2015 to 2020. The data collection was done by reviewing the records of smokers. We defined cessation as complete and continuous abstinence at 1 week, at 3 months, at 6 months and at 12 months and more. The study of cessation success factors involved subjects whose cessation was maintained for 1 year or more. RESULTS: Among 93 patients with coronary artery disease, the prevalences of smoking cessation rates were 54.8% (n = 51), 44.1% (n = 41), 35.5% (n = 33), 31.2% (n = 29), and 24.7% (n = 23) at 1 week, 1 month, 3 months, 6 months, and 12 months respectively. In univariate analysis, the number of visits greater than or equal to three (p = 0.000) and nicotine treatment (p = 0.018) were significantly associated with successful smoking cessation at 12 months. In multivariate analysis, being non-active (p = 0.028) with a Fagerstrom score <7 (p = 0.040) and three or more visits (p = 0.005) were the independent factors associated with successful smoking cessation at 12 months. CONCLUSION: The evaluation of the smoking cessation axis of therapeutic education of the coronary patient with tobacco addiction at the Sahloul University Hospital, allowed us to note that the cessation rate is comparable or even higher than that of other studies. However, the rate of maintenance of this cessation at 1 year and more proved to be low despite the strong motivation of the consultants. This observation allows us to better orientate the areas of improvement in the management of our consultants.

Assessing patient safety culture in 15 intensive care units: a mixed-methods study.

BACKGROUND: Within hospitals, intensive care units (ICUs) are particularly high-risk areas for medical errors and adverse events that could occur due to the complexity of care and the patients' fragile medical conditions. Assessing patient safety culture (PSC) is essential to have a broad view on patient safety issues, to orientate future improvement actions and optimize quality of care and patient safety outcomes. This study aimed at assessing PSC in 15 Tunisian ICUs using mixed methods approach. METHODS: A cross-sectional mixed methods approach using a sequential explanatory design was conducted from December 2019 to January 2020. The first quantitative stage was conducted in 15 ICUs belonging to the two university hospitals in the region of Sousse (Tunisia). All the 344 healthcare professionals (clinical staff) working for more than 1 month in these ICUs were contacted in order to take part in the study. In the second qualitative stage 12 participants were interviewed based on purposive sampling. RESULTS: All of the PSC dimensions had a score of less than 50%. The developed dimension was 'teamwork within units' (48.8%). The less developed dimensions were 'frequency of event reporting' (20.8%), 'communication openness' (22.2%) and 'non-punitive response to error' (19.7%). Interviews' thematic analysis revealed four main themes including "Hospital management/system failure", "Teamwork and communication", "Error management" and "Working conditions". CONCLUSION: This research revealed that PSC is still in need of improvement and provided a clearer picture of the patient safety issues that require specific attention. Improving PSC through the use of quality management and error reporting systems may help to improve patient safety outcomes.

Radical versus conservative surgical treatment of liver hydatid cysts: A paired comparison analysis.

BACKGROUND: The management of liver hydatid cysts (LHC) is complex and includes surgery, percutaneous drainage, chemotherapy and observation. Broadly, there are two types of surgical treatment for LHC - conservative surgery (CS) and radical surgery (RS). The purpose of this study was to compare the outcome of RS and CS. METHODS: Data from all patients with LHC treated in Sahloul Hospital, between January 2000 and December 2019, were retrieved. To minimize selection bias, paired comparison analysis (PCA) was performed. RESULTS: A total of 914 patients were included in this study. RS and CS were performed in 284 and 630 patients, respectively. After PCA, 206 patients were included in each group. The incidence of intraoperative bleeding was significantly higher in the RS group. The overall morbidity was significantly lower in the RS group. Thity-four patients developed recurrence with significantly higher recurrence in CS group. CONCLUSION: RS is associated with fewer postoperative complications and lower recurrence rate compared to CS. RS may be the preferred procedure for LHC if the expertise is available.

Trends of Healthcare-associated Infections in a Tuinisian University Hospital and Impact of COVID-19 Pandemic.

BACKGROUND: Although efforts to manage coronavirus disease 2019 (COVID-19) pandemic have understandably taken immediate priority, the impacts on traditional healthcare-associated infection (HAI) surveillance and prevention efforts remain concerning. AIM: To describe trends in HAIs in a Tunisian university hospital through repeated point prevalence surveys over 9 years, assess the impact of measures implemented for COVID-19 pandemic, and to identify associated factors of HAI. METHODS: The current study focused on data collected from annual point prevalence surveys conducted from 2012 to 2020. All types of HAIs as defined by the Centers for Disease Control and Prevention (CDC) were included. Data collection was carried out using NosoTun plug. Univariate and multivariate logistic analysis were used to identify HAI risk factors. RESULTS: Overall, 2729 patients were observed in the 9 surveys; the mean age was 48.3 ± 23.3 years and 57.5% were male. We identified 267 infected patients (9.8%) and 296 HAIs (10.8%). Pneumonia/lower respiratory tract infections were the most frequent HAI (24%), followed by urinary tract infection (20.9%).The prevalence of infected patients increased from 10.6% in 2012 to 14.9% in 2020. However, this increase was not statistically significant. The prevalence of HAIs increased significantly from 12.3% to 15.5% (P =.003). The only decrease involved is bloodstream infections (from 2% to 1%). Independent risk factors significantly associated with HAI were undergoing surgical intervention (aOR = 1.7), the use of antibiotic treatment in previous 6 months (aOR = 1.8), peripheral line (aOR=2), parenteral nutrition (aOR=2.4), urinary tract within 7 days (aOR=2.4), central line (aOR = 6.3), and prosthesis (aOR = 12.8), length of stay (aOR = 3), and the year of the survey. Young age was found as protective factor (aOR = .98). CONCLUSION: Contrary to what was expected, we noticed an increase in the HAIs rates despite the preventive measures put in place to control the COVID-19 pandemic. This was partly explained by the vulnerability of hospitalized patients during this period.

Multimodal intervention program to improve hand hygiene compliance: effectiveness and challenges.

BACKGROUND: Hand hygiene (HH) is considered the most important measure to tackle the transmission of healthcare-associated pathogens. However, compliance with recommendations is usually low and effective improvement strategies are needed. We aimed to assess the effectiveness of an intervention targeting hand hygiene promotion among healthcare workers (HCWs). METHODS: We conducted a pre-post interventional study design in the university hospital Sahloul, Sousse, Tunisia, from January 2015 to December 2016. The intervention program consisted of training sessions and distribution of posters of hand hygiene guidelines. To assess the evolution of HH observance at pre- and post-intervention, the same observation form was distributed and collected at healthcare workers' workplace. RESULTS: Of the 1201 and 1057 opportunities for hand hygiene observed among all categories of HCWs, overall compliance enhanced significantly from 32.1 to 39.4% (p < 0.001) respectively at pre- and post-intervention. Nurses were the most compliant with a significant improvement from 34.1 to 45.7% (p < 0.001) respectively at pre- and post-intervention. Furthermore, analysis by department showed significant improvement of compliance in orthopedic department (p < 0.001), maxillofacial-surgery department (p < 0.001), pediatrics department (p = 0.013), and emergencies (p = 0.038). CONCLUSION: This study showed the feasibility and effectiveness of a health-setting-based intervention to enhance hand hygiene observance in the context of a developing country.

Effect of a school-based intervention in eating habits among school children: quasi experimental study, Tunisia.

OBJECTIVE: The present study aimed to assess whether six months intervention program with parents' implication in primary schools is able to decrease morning snack consumption among children aged 6-12 years. METHODS: We carried out a quasi-experimental study with two groups of schoolchildren in the region of Sousse (Tunisia) from 2015 to 2016. One primary school in each group was selected. In each school, we randomly selected a sample size of schoolchildren and their parents. The intervention was based on healthy eating habits promotion. RESULTS: The consumption of morning snacks the day before data collection, reported by children, decreased significantly in post-intervention in both intervention and control groups. The decrease of consumption of morning snacks was significantly higher in intervention group (p=0.009). According to parents, the proportion of children who had the habit of eating morning snack decreased significantly from pre to post-intervention in intervention group (p<0.001). CONCLUSION: A healthy environment should be created through effective school policies to prevent obesity.

[Perceptions of a healthcare-associated infections reporting system in a Tunisian university hospital]. / Perceptions d'un système de signalement des infections associées aux soins dans un hôpital universitaire tunisien.

Objective: The implementation of a healthcare-associated infections reporting system is a principal component of infection control and quality improvement policies in healthcare institutions. This study was designed to determine the perceptions of health professionals concerning implementation of a healthcare-associated infections reporting system and to analyse factors influencing these perceptions.Methods: A descriptive cross-sectional study conducted in 2012 using a predefined, pre-tested and self-administered questionnaire in 380 health professionals working in 16 different departments of Farhat Hached University Hospital, Tunisia.Results: The majority of respondents (71.8%) reported that no healthcare-associated infections surveillance procedure had been implemented in their departments. However, most respondents (93%) recognised the value of implementation of a healthcare-associated infections reporting system in order to provide them with corrective actions (77%), to support the investigation of epidemic and emerging phenomena (49%) and to share experiences about the prevalence of healthcare-associated infections and their risk factors (44%).Conclusion: Staff training and development of a regulatory framework are essential to implementation and correct functioning of a healthcare-associated infections reporting system.

[Incidence of device-associated infections in a Tunisian intensive care unit]. / Incidence des infections associées aux dispositifs médicaux dans un service de réanimation tunisien.

INTRODUCTION: Healthcare-associated infections represent a real public health problem. They are particularly frequent and severe in intensive care units due to the serious diseases presented by patients and the almost systematic use ofvarious medical devices. A study of the incidence of device-associated infections was conducted in the ICU of CHU Farhat Hached Sousse (Tunisia) to estimate the incidence and to identify risk factorsfor DAI METHODS: This prospective incidence study was conducted during the first quarter of 2012, with anonymous and standardized data collection for all patients hospitalized for at least 48 hours. RESULTS: Out of a total of 105 patients hospitalizedfor more than 48 hours during the study period, 17 cases of DAI were identified. The incidence density was 16.9 infected patients / 1,000 days of hospitalization. The infections most frequently identified were central and peripheral venous catheter-associated infections. Independent riskfactorsfor DAI in the ICUwere length of ICU stays which increased the risk of DAI by 1.10 per day (95% CI [1.03 - 1.17]; p=0.002), and the use of CVC, which increased the risk by 3.29 (95% CI [1.36 - 7.95]; p=0.031). CONCLUSION: The implementation of continuous surveillance of healthcare-associated infection in the intensive care unit should be encouraged in order to guide the actions of prevention and control of nosocomial infection risk.

Healthcare-associated infections in a Tunisian university hospital: from analysis to action.

INTRODUCTION: Our study was conducted, in university hospital center (UHC) Farhat Hached of Sousse (city in Tunisian center-east), within healthcare-associated infections (HAI) epidemiological surveillance (ES) program, based, among others, on HAI regular prevalence surveys. Our objectives are to resituate HAI prevalence rate and to identify their risk factors (RF) in order to adjust, in our hospital, prevention programs. METHODS: It is a transversal descriptive study, including all patients who had been hospitalized for at least 48 hours, measuring prevalence of HAI a "given day", with only one passage by service. Risk factors were determined using Epiinfo 6.0, by uni-varied analysis, then, logistic regression stepwise descending for the variables whose p. RESULTS: The study focused on 312 patients. Infected patients prevalence was 12.5% and that of HAI was 14.5%. Infections on peripheral venous catheter (PVC) dominated (42.2%) among all HAI identified. HAI significant RF were neutropenia (p < 10(-4)) for intrinsic factors, and PVC for extrinsic factors (p = 0,003). CONCLUSION: Predominance of infections on PVC should be subject of specific prevention actions, including retro-information strategy, prospective ES, professional practices evaluation and finally training and increasing awareness of health personnel with hygiene measures. Finally, development of a patient safety culture with personnel ensures best adherence to hygiene measures and HAI prevention.

Risk of mortality due to device associated infection.

BACKGROUND: Intensive care unit -acquired infections constitute an important worldwide health problem. AIM: Our aim was to determine the incidence and risk factors of device-associated infection and those of mortality in a Tunisia ICU. METHODS: We conducted a prospective observational cohort study over a six months period in the adult medical intensive care unit of University Hospital-Farhat Hached (Sousse-Tunisia). Patients admitted to the unit were included in the study if they stayed in the ICU for more than 48 hours. RESULTS: During the study period, 105 patients were surveyed; 16 of them (15.2%) developed 17 episodes of device associated infections (16.9 DAI/1000 days of hospitalization). The most frequently identified infections were central and peripheral venous catheter -associated infection (respectively, 21.4 CVC-AI/ 1000 CVC-days and 10.2 PVCAI / 1000 PVC-days). At ICU discharge, overall mortality was 40%. Independent risk factors for acquiring infection in ICU were the use of central venous catheter (p=0.031) and length stay (0.002), those of mortality in ICU were immunosuppression (p=0.013), DAI (p=0.002) and the use of central venous catheter (p = 0.001). CONCLUSION: Even if DAI rates in Tunisian ICU were lower than those published in some reports from other North African countries, DAI data and mortality rate, dominated by the use of catheter associated infections show the need for more-effective infection control interventions in our hospital.

[Measuring patient safety awareness among physicians in a Tunisian hospital]. / Mesure de la culture sécurité des soins auprès des médecins dans un hôpital tunisien.

AIMS: The objective of this study was to measure the level of awareness of patient safety among physicians at Farhat Hached hospital in Sousse (Tunisia). METHODS: A cross-sectional descriptive study was conducted in 2012 using a validated survey based on pervious studies. This self-administered questionnaire was distributed to 116 physicians working in 16 different departments of Farhat Hached university hospital. This survey explores 10 dimensions of patient safety and each of these dimensions is composed of several items. The percentage of positive (positive attitudes) and negative responses for each item was calculated and a score was calculated for each dimension, corresponding to the mean percentages of positive answers to the respective items of the dimension. RESULTS: The response rate was 74.1%. The overall positive response rate of patient safety awareness ranged from 13.9% to 84%. The dimensions with the lowest positive response rates were "Hospital management support for patient safety" (13.9%) and "Teamwork within units" (45.4%). The highest percentage of positive responses was observed for "Supervisor expectations and safety-promoting actions" (82.3%) and "Frequency of event reporting" (84%). CONCLUSION: This study measured the level of awareness of patient safety among physicians at Farhat Hached university hospital. The results obtained will be used to guide safety-promoting actions.
