[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.

Factors Associated with Diagnostic Delays among Tunisian Breast Cancer Patients.

BACKGROUND: Breast cancer (BC) remains one of the most common and deadliest cancer among women worldwide and in Tunisia. The lethality of BC is particularly high in developing countries, such as Tunisia, due to late diagnosis in the majority of cases. The objective of this study was to analyze factors associated with delayed presentation among women followed at the Salah Azaiez institute of Tunis during the year 2021. METHODS: It was a retrospective cohort study, including patients with primary BC, consulting at the Salah Azaeiz institute of Tunis over a period of six months, from january 1st to june, 30th, 2021. The total diagnostic interval (DI) was divided into patient interval (PI) and healthcare system interval (HSI). Diagnosis delay due to patient (PD) was defined as a delay more than three months between the discovery of symptoms and the first medical consultation. Data were collected using a valid questionnaire "the breast cancer questionnaire delay" and from patients' medical records. The calculation of crude and adjusted Odds Ratios using a stepwise descending binary logistic regression model was performed to measure the association of the studied factors with the delayed presentation. RESULTS: A total, 146 patients were included. The mean age of the patients was 50.1 ± 10.9 years.  More than a half of patients had a primary education (56.8%). Majority of patients were married (86.3%) and unemployed (90.4%).  The median of patient interval (PI) and HSI were 31 days [IQR: 12.5-151.5] and 53 days [IQR: 33.0-88.7] respectively. About three quarter of patients (76.4%) presented a healthcare system delay (HSD). After univariate analysis, factors significantly associated with PD were the low level of education (illiterate/primary) (RR: 2.7; 95% CI [1.1-6.4]; p=0.02) and the lack of knowledge about BC symptoms by patients (RR: 15.0; 95% CI [6.0-37.4]; p<10-3). The only variable that remained associated with PD, after multivariate analysis, was lack of initial knowledge of symptoms (OR: 15.0; 95% CI [6.0-37.4]; p<10-3). CONCLUSION: Lack of knowledge of symptoms was the main factor associated with delayed presentation among BC women.This study shows the need to inform women about performing breast self-examination as well as clinical signs of BC.

[Evaluating the performance of Tunisian regional hospitals. Study Protocol of management delays of ST elevation myocardial infarction].

RESEARCH PROBLEM: ST Elevation Myocardial Infarction (STEMI+) is an absolute emergency. The young age of patients and the difficulty of access to care remain the main characteristics of STEMI+ management in Tunisia. In the governorate of Béja, located in the Northwestern region of Tunisia, given the lack of a cardiology interventional room in the hospital and in the private establishments of the region and the distance from the specialized centers of at least 127 km, the patient is beyond 90 min of the transfer. This delay in care generates a heavy burden of morbidity and mortality. The main objective of this study will be to audit the delays of management of patients presenting STEMI+ at the regional hospital of Béja (Tunisia) in accordance with the recommendations of learned societies. Secondarily, we will identify factors associated with delayed presentation after the onset of clinical symptoms. Investigation process : it will be a descriptive, exhaustive and prospective study, including patients admitted to the emergency and/or the cardiology department of the regional hospital of Béja for STEMI+ during the study period. For each patient admitted for STEMI, the following data will be collected : sociodemographic characteristics; medical history; cardiovascular risk factors; diagnostic and therapeutic management modalities; intra-hospital evolution; survival at 01 months in relation to the current coronary episode and the estimation of the different management delays. RESEARCH PLAN: ethical considerations will be respected, as well as the confidentiality and anonymity of the data. The study will last one year from the 1st september 2022 to 31 august 2023. The results will allow us to describe the delays of management of patients with STEMI+ in the region of Béja (Tunisia). At least 2 publications in international scientific journals are planned.

Barriers affecting patient adherence to intermittent self-catheterisation.

Intermittent self-catheterisation (ISC) is now considered the standard of care for most patients with neurological conditions and associated lower urinary tract disorders. Numerous societies, led by the International Continence Society, are in agreement on the effectiveness of ISC. Use of intermittent catheters is reported to reduce the risk of catheter-associated urinary tract infection compared with indwelling urinary catheters while improving patient comfort and quality of life. However, previous studies have shown that, despite the benefits of ISC, it will not guarantee behavior change and the integration of this procedure into the daily life of patients. Patients may encounter internal (related to the patient themselves) and external (related to their environment) difficulties. Identifying these obstacles early will help promoting ISC success. This review aims to identify internal and external barriers related to ISC and to propose adequate solutions to avoid them.

Intermittent catheterisation: the common complications.

Intermittent catheterisation (IC) has been in practice for more than 40 years and is considered the gold standard in the management of urinary retention in the neurological bladder. IC has many advantages over indwelling urethral or suprapubic catheterisation, including reducing the risk of infection, protecting the bladder and improving quality of life. However, complications can be caused by the practice of this technique, the most common of which is infection. This review discusses some of the common complications that can occur with the use of intermittent catheterisation, including urinary tract infection (UTIs) and urethral complications. It also highlights the role of the nurse in the management of its complications.

Teaching patients clean intermittent self-catheterisation: key points.

Intermittent self-catheterisation (ISC) is recognised as the gold standard for the treatment of neurological bladders. ISC involves the introduction of a catheter by the patient into the bladder and its immediate removal when drainage stops. This process needs to be repeated four to six times a day. Therapeutic patient education (TPE) is commonly used nowadays to treat and care for patients with chronic disease. Community nurses can play an active role in introducing ISC to patients and teaching them to perform it. This review emphasises the important points to consider when teaching patients ISC.

Effectiveness of ECG educational workshops among undergraduate medical students.

BACKGROUND: The electrocardiogram (ECG) remains one of the most important and commonly used diagnostic tools in medicine. At the faculty of Medicine of Tunis (FMT), teaching ECG interpretation to undergraduate medical students is an important part of the curriculum. AIMS: To assess the effectiveness of pedagogical workshops in ECG learning among students of First-year of the primary cycle of medical studies (PCMS 1). In addition, we aimed to assess the students' perceptions of the tutorials. METHODS: It was an exhaustive cross-sectional study that was carried out at the FMT during the academic year 2017-2018 and that included students from PCMS 1. All participants completed a pre-test, a workshop session and a post-test. Each of the tests consists of five Multiple Choice Questions (MCQs) covering the same topics. An evaluation of students' satisfaction with the tutorial was made at the end of the session. RESULTS: Ten workshops were held at the FMT, including 160 students. The overall score increased from 4 out of 10 points in the pre-test to 6.8 out of 10 points in the post-test (p <0.001). A statistically significant improvement was noted in all tests questions (p<0.001). Sixty-one learners (39.3%) were "Not satisfied" with the number of students per group. On the whole, 83.8% (n=130) of students found the session beneficial. CONCLUSIONS: Students indicated a positive attitude toward the workshop and its utility. More research among similar populations is needed to support these conclusions and to assess the effectiveness of medium- and long-term educational workshops on medical students.
