A Qualitative Study of Doxycycline Post-Exposure Prophylaxis Knowledge, Attitudes and Practices Among Healthcare Providers in New York City

Abstract Background Three randomized controlled trials have demonstrated the efficacy of doxycycline for bacterial sexually transmitted infection post-exposure prophylaxis (Doxy PEP). Few studies have assessed provider knowledge, attitudes, and practices (KAP) regarding Doxy PEP implementation. Between July of 2023 and January 2024, this study qualitatively assessed KAP and intention to prescribe Doxy PEP among healthcare providers in the New York City area. Methods In-depth, semi-structured individual interviews were conducted with 18 healthcare provider key informants including physicians, nurse practitioners and physician assistants from various practice settings. Transcripts were analyzed using inductive KAP codes, with additional deductive coding used to identify emergent subthemes. Results The following themes were identified: (1) STI Disparities, (2) Doxy PEP Experience, (3) Doxy PEP Benefits, (4) Doxy PEP Concerns, and (5) Doxy PEP Implementation. Doxy PEP knowledge was high, with all providers being aware and most (78%) having prescribed it to at least one patient at the time of interview. Providers were knowledgeable of factors contributing to high rates of STIs. Benefits included reducing STI anxiety. Concerns included contributing to antimicrobial resistance and impacts on microbiota. Practice implications included challenges getting Doxy PEP approved by the pharmacy. These factors were shown to affect Doxy PEP’s perceived acceptability. Conclusions To ensure that Doxy PEP is implemented safely and equitably, KAP factors that may influence provider decision-making should be examined. Understanding providers’ knowledge, attitudes, and practices and how they affect intention to prescribe Doxy PEP, and to what patients, has important implications for successful implementation.

Clinical practice pattern of Pneumocystis pneumonia prophylaxis in systemic lupus erythematosus: a cross-sectional study from lupus registry of nationwide institutions (LUNA)

BackgroundPneumocystis jirovecii pneumonia (PCP) is an opportunistic infection in patients undergoing immunosuppressive therapy, such as glucocorticoid (GC) medication, for systemic autoimmune diseases like systemic lupus erythematosus (SLE). Despite the confirmed effectiveness of PCP prophylaxis, its clinical administration, especially in conjunction with GC dosage, remains unclear. We aimed to describe the clinical practice of PCP prophylaxis in association with SLE in Japan, evaluate the relationship between GC dosage and PCP prophylaxis, and explore the practice patterns associated with PCP prophylaxis.MethodsThis cross-sectional study used data from the Lupus Registry of Nationwide Institutions in Japan from 2016 to 2021 and included patients diagnosed with SLE. Using descriptive statistics, multivariate analysis, and decision tree analysis, we examined the prevalence of PCP prophylaxis and its association with the GC dosage.ResultsOut of 1,460 patients, 21% underwent PCP prophylaxis. The frequency of prophylaxis decreased with a decrease in GC dosage. After adjusting for confounders, logistic regression revealed the odds ratio of PCP prophylaxis increased with higher prednisolone (PSL) doses: 3.7 for 5 ≤ PSL < 7.5 mg, 5.2 for 7.5 ≤ PSL < 10 mg, 9.0 for 10 ≤ PSL < 20 mg, and 43.1 for PSL ≥ 20 mg, using PSL < 5 mg as the reference. Decision tree analysis indicated that a PSL dosage of < 11 mg/day and immunosuppressant use were key determinants of PCP prophylaxis.ConclusionThis study provides valuable insights into PCP prophylaxis practices in patients with SLE in Japan, underscoring the importance of GC dosage and concomitant immunosuppressant use.

Liver transplantation for HBV-related liver disease: impact of prophylaxis for HBV on HCC recurrence.

Background and aimsConflicting data exist regarding optimal prophylaxis for HBV recurrence (HBV-R) after liver transplantation (LT), particularly in patients with hepatocellular carcinoma (HCC). We assessed current practices for HBV-R prophylaxis in Italy, evaluating rates, risk factors, and clinical impact of HBV-R and HCC-R. MethodsMulticentric, retrospective study involving 20 Italian LT centers. All patients who underwent LT for HBV-related liver diseases between 2010 and 2021 were included. Logistic regression was used to identify predictors of HBV-R and HCC-R. Survival curves were estimated with Kaplan-Meier method and compared with log-rank test. ResultsWe included 1205 LT recipients (60.8% HCC). HBV prophylaxis was prescribed in 99.7% recipients, mostly with lifelong HBIG+NUCs (83.9%). Rates of HBV-R were 2.1% and 3.1% in patients transplanted without and with HCC, respectively. Median times from LT were 60 [9.5–77.5] and 5.5 [1–13] months, respectively. Recipients on lifelong HBIG+NUCs experienced lower rates of HBV-R than those in whom HBIG were withdrawn, used only during LT, or received NUCs alone (2.3% vs. 6.2% vs. 1.9% vs. 8%, respectively; p=0.042). In HCC recipients, HCC-R rate was 10.8% (median time from LT: 18 months). At multivariate analysis, HBV-R (OR: 10.329; 95%CI: 3.665-29.110), Child-Pugh C (OR: 3.519; 95%CI: 1.305-9.484), and microvascular invasion (OR: 3.088; 95%CI: 1.692-5.634) were independently associated with HCC-R. Five-year survival was lower in recipients who experienced HCC-R (32.5% vs. 92.4% in those who did not; p<0.001). ConclusionIn Italy, HBV prophylaxis is mostly based on lifelong HBIG+NUCs. HBV-R was rare and not associated with survival in patients transplanted for decompensated cirrhosis. In patients transplanted for HCC, HBV-R was independently associated with HCC-R. The clinical implications of these findings deserve further investigation.

Antiseizure medication practices in the adult traumatic brain injury patient population

BackgroundAntiseizure medication (ASM) use in traumatic brain injuries (TBI) reduces the risk of early post-traumatic seizure (PTS). Agent selection and dosing strategies remain inconsistent among trauma centers in the United States. ObjectiveThe purpose of this study was to identify and characterize the most common PTS prophylaxis regimens among adult trauma centers in brain injured patients throughout the United States. MethodsA survey assessing PTS prophylaxis practices of trauma centers was created and distributed in March 2023. Data was then evaluated based on practice site demographics and various sub-group analyses including academic vs. non-academic centers, trauma center designation, geographic practice location, and total number of TBI activations annually. ResultsA total of 84 different trauma centers responded of which, 82 (97.6 %) respondents reporting levetiracetam (LEV) as their ASM of choice for PTS prophylaxis. The most reported dosing regimen included an initial dose of 1000 mg (n = 24, 46.2 %) followed by a maintenance dose of 500 mg BID (n = 39, 48.8 %). There were no statistically significant differences in practice between sub-group analyses evaluated. Conclusion and relevanceThis multicenter, survey study, identified variances in practice for PTS prophylaxis for brain injured patients throughout the U.S. Interestingly, the overwhelming majority of trauma centers do not conform to the Brain Trauma Foundation guidelines and utilize LEV as their agent of choice. Further studies should evaluate ideal patient selection for PTS prophylaxis, optimal agent, and dosing schemes within this cohort.

Venous Thromboembolism Risk Assessment and Thromboprophylaxis Practice in Hospitalized Medical Patients: The Experience of a Singapore Teaching Hospital

AbstractDespite the availability of institutional guidelines, the practice of venous thromboembolism (VTE) risk assessment and thromboprophylaxis remains inadequate in Singapore. With hospital-associated VTE (HA-VTE) being a common cause of preventable mortality for medical patients, it is vital for prompt, appropriate prescription of thromboprophylaxis after VTE risk assessment. This study aimed to (1) assess the local practice of VTE risk assessment and prophylaxis according to institutional guidelines, (2) study the risk factors of potential preventable HA-VTE among hospitalized medical patients, and (3) improve the quality of care with respect to early prevention of HA-VTE. An audit was performed on daily new admissions to two general medical wards in a teaching hospital in Singapore (total capacity of 76 beds) over 2 weeks. Each new admission's medical records were reviewed to examine whether (1) VTE risk assessment was performed by the managing medical teams, (2) thromboprophylaxis was prescribed during admission in high VTE risk patients, and (3) any contraindications to pharmacological thromboprophylaxis for cases with high VTE risk but no pharmacological thromboprophylaxis prescribed was present. Only 1 out of 52 cases had VTE risk assessment performed. Thirty-one cases (59.1%) were identified to have high VTE risk using the Padua Prediction Score. However, only 1 out of the 31 cases (3.2%) had VTE prophylaxis prescribed. Adherence to local institutional guidelines remains poor despite increasing awareness of the importance of VTE risk assessment and prophylaxis in the prevention of associated morbidity and mortality. Certain patient profiles should prompt clinicians to perform VTE risk assessment.

Practice variation in venous thromboembolism prophylaxis in adolescent trauma patients: A comparative analysis of pediatric, adult, and mixed trauma centers

IntroductionAdolescent trauma patients are at increased risk of venous thromboembolism (VTE). It is unclear whether VTE prophylaxis practice patterns differ across trauma center types. MethodsThe ACS-TQP database was queried for patients aged 12-17 admitted to a pediatric, adult, or mixed level I/II trauma center. VTE prophylaxis was compared between center types. Preplanned subgroup analyses were performed to evaluate guideline adherence. ResultsOf 101,010 patients included, 35 ​% were treated at a pediatric trauma center (PTC), 43 ​% at a mixed trauma center (MTC), and 22 ​% at an adult trauma center (ATC). VTE prophylaxis was more common at ATCs and MTCs compared to PTCs (51.0 ​% vs 24.9 ​% vs 5.0 ​%,p ​< ​0.001). This trend persisted in subgroup analyses of patients aged 16–17 (63.8 ​% vs 40.5 ​% vs 6.4 ​%,p ​< ​0.001) and with injury severity score greater than 25 (83.8 ​% vs 74.0 ​% vs 35.1 ​%,p ​< ​0.001). ConclusionVTE prophylaxis is administered more frequently to adolescent trauma patients treated at ATCs and MTCs compared to PTCs despite published guidelines. Prospective studies are needed to assess the clinical utility of VTE prophylaxis in the adolescent trauma population.

Evaluating chemical venous thromboembolism prophylaxis in trauma patients at a single Australian center.

Trauma patients are at an elevated risk of developing venous thromboembolism (VTE), with the subsequent mortality in patients requiring intensive care unit admission ranging from 25% to 38%. There remains significant variability in clinical practice related to VTE prophylaxis in trauma patients due to the frequent presence of contraindications impacting the timing and consistency of application. This study aimed to assess the effectiveness of the current practice of chemical VTE prophylaxis in trauma patients at a single Australian center. A prospective review was conducted on patients admitted to the ACT Trauma Service (Canberra, Australia) from July to November 2022. The included patients were 18 years or older, without a direct contraindication to anticoagulation, who received chemical VTE prophylaxis with low-molecular-weight heparin (enoxaparin) for at least three doses and underwent subsequent testing of anti-factor Xa (aFXa) levels. During the study period, 187 patients were admitted, of whom 63 were included in the study. Of these, 47 patients achieved therapeutic levels of anticoagulation as determined by their aFXa levels, while 16 were subtherapeutic. The only statistically significant difference between the two groups was in weight, with patients in the subtherapeutic group weighing an average of 91.9 kg compared to 79.1 kg in the therapeutic group (P<0.05). A fixed-dose enoxaparin regimen was utilized, with limited individualization based on patient factors, such as injuries, comorbidities, and other biological factors. Sixteen patients (25%) had subtherapeutic VTE prophylaxis, as measured by aFXa levels. Higher weight was significantly correlated with inadequate VTE prophylaxis dosing. While age, sex, and smoking status might play important roles in clinical decision-making, weight-based dosing of low-molecular-weight heparin may be more effective in achieving adequate VTE prophylaxis.

Antibiotic prophylaxis practice in gastrointestinal surgery in five hospitals in southern Benin

BackgroundBenin’s healthcare system is characterized by a lack of local guidelines for surgical antibiotic prophylaxis (SAP), which is essential to prevent surgical site infection. AimTo audit compliance for SAP practices in gastrointestinal surgery. MethodsData were prospectively collected from gastrointestinal surgery departments in five hospitals. Over a four month period, SAP was assessed using five conventional criteria (indication, choice of antibiotic, dosage, timing, and duration of administration) among patients admitted for Altemeier class 1 or 2 procedures. Three guidelines were used as reference: World Health Organization (WHO), American Society of Health-System Pharmacists (ASHP)and French Society of Anaesthesia and Intensive Care Medicine (SFAR). FindingsOf 68 surgical interventions, overall compliance with WHO, ASHP, and SFAR was observed in zero (0.0%), one case (1.5%) and two cases (2.9%), respectively. Compliance with indication varied according to the guidelines: 65 (95.6%) were compliant with WHO and ASHP and 47 cases (69.11%) with SFAR. Among compliant cases, the antibiotics administered were rarely selected according to guidelines: WHO, 2 (2.9%) and ASHP, 2 (2.9%), and SFAR, 3 (4.4%). Drug dosage compliance varied from 20 (29.4%) (SFAR) to 49 (72.0%) (ASHP). Timings were respected in 47 (69.1%; WHO), 45 (66.2%; ASHP) and 9 cases (13.2%; SFAR). The number of cases compliant with antibiotic prophylaxis duration were 13 (19.1%; WHO), 17 (25.0%; ASHP) and 16 (23.5%; SFAR). ConclusionThe SAP compliance rate in gastrointestinal surgery based on the five conventional criteria was very low. SAP guidelines must be implemented appropriately for local bacteriological epidemiology.

EP51 - Uses of pharmaceutical and mechanical VTE prophylaxis - A clinical audit

Abstract Aim Venous thromboembolism (VTE) is a serious global health care safety concern for both patients and staff. Although it has been amply demonstrated that pharmaceutical and mechanical methods of prophylaxis against VTE are effective, their application has been uneven and insufficient. The purpose of this audit was to assess junior physicians working in general surgery, regarding their adherence to local and NICE guidelines regarding the pharmacological VTE prophylaxis practice as well as the mechanical prophylaxis Methodology Pre-intervention audit took place for two weeks. Throughout the course, it covered every adult general surgical emergency inpatient admission at conquest hospital who were deemed indicated for VTE prophylaxis. Each evening while the patients were still in the hospital, data was collected using the prescription charts, nursing and medical notes. The proforma used for data collection detailed the characteristics of VTE risk, the prophylactic medication prescribed for each patient, TED stockings and whether or not this aligned with the NICE clinical guideline (CG) 46,6.8. Post intervention took place for two weeks after teaching of junior doctors and the same as above was carried out, using the new proforma Results Pre-intervention showed that 87% of patients had the proforma filled in and 100% of patients received the appropriate dose of pharmaceutical prophylaxis. However, less than 40% of patients received the appropriate mechanical prophylaxis. Therefore, intervention was made in the form of a new proforma and teaching to junior. Post intervention data is currently being carried out Conclusion Implementation was necessary to ensure that at-risk patients receive appropriate prophylaxis.

Lubratex eye ointment with polyethylene cover significantly reduces corneal abrasion in ICU patients: a randomized controlled trial

Corneal abrasion is a frequent complication in critically ill, intubated patients, potentially leading to visual impairment. This study compares the efficacy of three ocular care methods in preventing corneal abrasion among this vulnerable population. We conducted a randomized controlled trial involving 156 intubated adult patients admitted to the ICU. Participants were randomly allocated to one of three intervention groups (n = 52 per group): (1) polyethylene cover only, (2) polyethylene cover with artificial tear drops, and (3) polyethylene cover with Lubratex eye ointment. One eye per patient was randomly assigned as the control, receiving standard ICU eye care. Daily assessments over five days included a standardized dryness and corneal abrasion checklist, graded strip evaluation of eye dryness, and documentation of corneal abrasion incidence. Data were analyzed using descriptive and inferential statistics (SPSS-18). The incidence of corneal abrasion was significantly lower in the group receiving polyethylene cover with Lubratex eye ointment (4%) compared to the polyethylene cover with artificial tears group (36%, p < 0.001) and the polyethylene cover only group (60%, p < 0.001). The combined application of a polyethylene cover with Lubratex eye ointment effectively prevents corneal abrasion in intubated ICU patients. This method demonstrates superior efficacy compared to polyethylene covers used alone or with artificial tears. We recommend its implementation as standard practice for corneal abrasion prophylaxis in this high-risk population.Trial Registration.

Live Vaccine and Varicella Postexposure Prophylaxis in Pediatric Liver Transplant Recipients: A Survey of Practice in Australia and New Zealand.

Administration of live vaccines following liver transplant (LT) has historically not been recommended due to concerns regarding risk of vaccine-attenuated disease. However, there is evidence suggesting that in select transplant recipients live vaccinations can be administered safely. Studies in other regions have indicated that despite this evidence many clinicians remain hesitant to administer live vaccinations. A REDCap survey was distributed to gastroenterologists, pediatricians, and infectious diseases physicians at pediatric centers across Australia and New Zealand via email between September and November 2023. The survey included a series of questions regarding live vaccine and varicella postexposure prophylaxis (PEP) practices in pediatric LT recipients and barriers to live vaccine administration in this cohort. There was a total of 16 responses to the survey, from 10 different pediatric centers, including 10/11 pediatric gastroenterology centers and all four pediatric LT centers in the region. Only 31% (5/16) of respondents (from 3/10 different centers) offer live vaccines. The main barrier to live vaccine administration was clinician reluctance and the main reason for not offering live vaccines was insufficient safety data. Sixty-nine percent (11/16) of respondents take vaccination status and/or serology into account when deciding whether to offer varicella PEP to this cohort. Respondents universally offer varicella zoster immunoglobulin as PEP, though 31% (5/16) also offer antiviral medication. Many clinicians in our region remain hesitant to provide live vaccines to pediatric LT recipients, with concerns regarding insufficient safety data. Updated local guidelines may help to address this.

Infections and antimicrobial prophylaxis in patients with myelodysplastic syndromes

Infectious complications are an important cause of morbidity and mortality in patients with myelodysplastic syndromes (MDS). Preventing infections could significantly improve both survival and quality of life. Unfortunately, both infections and antimicrobial prophylaxis in patients with MDS are incompletely assessed due to the heterogeneity of disorders included in each publication, changing definitions over time, and lack of standardized prophylaxis practices. Despite these limitations, some basic statements can be made. Infections in MDS are associated with neutropenia. Patients with lower-risk (LR) MDS tend to have fewer infections compared to patients with higher-risk (HR) MDS, which may be related to the different prevalence of neutropenia in the 2 groups. Pneumonia is the most common infection, and bacteria are the most common pathogens. Invasive fungal infections (IFI) are uncommon. Reactivation of latent viruses are rare. With the limited data available, we agree that antibacterial prophylaxis can be considered in patients with HR-MDS during severe neutropenia and early cycles of therapy when infections are most likely to occur. Given the low prevalence of IFI and viral reactivation, antimicrobial prophylaxis for these pathogens is less likely to be advantageous for most patients, although antifungal prophylaxis with activity against mold is commonly used in patients with persistent, profound neutropenia. Ultimately, improved data collection regarding infections and antimicrobial prophylaxis is needed to improve care for patients with MDS.

Variance in Pneumocystis jirovecii prophylaxis practice for pediatric patients undergoing hematopoietic cell transplantation.

Pneumocystis jirovecii pneumonia (PJP) in hematopoietic cell transplant (HCT) recipients can be prevented by efficient prophylaxis. We surveyed HCT centers in North America to assess their PJP prophylaxis practices. Most institutions used intravenous (IV) pentamidine (29.6%) or inhaled pentamidine (14.8%); 37% institutions changed from trimethoprim/sulfamethoxazole (TMP-SMX) to another medication after conditioning; and 44% administered no PJP prophylaxis during the pre-engraftment period. Most institutions avoided using TMP-SMX during the pre-engraftment period, mainly because of concerns about myelotoxicity, despite this being the preferred PJP prophylaxis agent. There is a need to evaluate the effects of TMP-SMX on engraftment.

Risk factors of peritoneal dialysis-related peritonitis in the Japan Peritoneal Dialysis Outcomes and Practice Patterns Study (PDOPPS).

Peritoneal dialysis (PD)-related peritonitis is a major complication of PD. Wide variations in peritonitis prevention, treatment strategies and consequences are seen between countries. These between-country differences may result from modifiable risk factors and clinical practices. A total of 1225 Japanese PD patients were included and prospectively followed in the Peritoneal Dialysis Outcomes and Practice Patterns Study phase 1 (2014-2018) and phase 2 (2018-2022). Associations between PD-related peritonitis and various risk factors were assessed by Cox proportional hazards survival models. During follow-up (median 1.52years), 539 peritonitis episodes were experienced by 364 patients. The country crude peritonitis rate was 0.27 episodes/patient-year. In the fully adjusted model, noticeable patient-level factors associated with experiencing any peritonitis included age {hazard ratio [HR] 1.07 per 5-year increase [95% confidence interval (CI) 1.01-1.14]}, serum albumin level [HR 0.63 per 1g/dl higher (95% CI 0.48-0.82)] and continuous ambulatory peritoneal dialysis (PD) [HR 1.31 versus automated PD (95% CI 1.05-1.63)]. The adoption of antibiotic prophylaxis practice at the time of PD catheter insertion [HR 0.63 (95% CI 0.51-0.78)] or when having complicated dental procedures [HR 0.74 (95% CI 0.57-0.95)] or lower endoscopy [HR 0.69 (95% CI 0.54-0.89)] were associated with lower hazards of any peritonitis, while a routine facility practice of having more frequent regular medical visits was associated with a higher hazard. Identification of risk factors in Japan may be useful for developing future versions of guidelines and improving clinical practices in Japan. Investigation of country-level risk factors for PD-related peritonitis is useful for developing and implementing local peritonitis prevention and treatment strategies.

Challenges for the improvement of valganciclovir prophylaxis in solid organ transplantation and the possible role of therapeutic drug monitoring in adults.

Cytomegalovirus (CMV) infection frequently occurs after solid organ transplantation and is associated with an increased morbidity and mortality. Fortunately, the development of valganciclovir prophylaxis has lowered the incidence of CMV infection and its complications in immunosuppressed solid organ transplant recipients. However, breakthrough infections during valganciclovir prophylaxis and late CMV infection after cessation of valganciclovir prophylaxis still occur with the current prophylactic strategy. Additionally, valganciclovir resistance has emerged among CMV strains, which complicates the treatment of CMV infections. Furthermore, the use of valganciclovir is associated with myelotoxicity, which can lead to the premature withdrawal of prophylaxis. It is important to address these current issues in order to improve the standard care after solid organ transplantation. This paper will therefore discuss the clinical practice of valganciclovir prophylaxis, elaborate on its issues and suggest how to improve the current prophylactic strategy with a possible role for therapeutic drug monitoring.

VTE prophylaxis for major abdominal surgery: A hospital audit and nurses' survey for quality improvement

Objective: The objective of this study is to assess and improve VTE prophylaxis practices in major abdominal surgery through a hospital audit and nurses' survey. Primary aims: Evaluate adherence to VTE prophylaxis guidelines in abdominal surgery, identify improvement opportunities in VTE prevention and assess the effectiveness of current prophylactic measures. Nurses’ survey: Evaluate surgical nurses' knowledge and implementation of VTE prophylaxis and identify educational gaps to improve VTE prevention. Secondary aims: Integrate audit and survey insights: Gain insight into VTE management practices, to develop quality improvement programs for better prophylaxis and outcomes. Background: Guidelines for the prevention of venous thromboembolism (VTE) in surgical patients involve risk assessment, followed by chemical and mechanical prophylaxis. Often, VTE risk assessments are not completed which leads to inappropriate or inadequate prophylaxis. The current guidelines suggest that a healthcare provider, such as a nurse or physician, should conduct the VTE risk assessment for each patient. Study design and methods: Initially, a prospective audit was conducted to examine VTE prophylaxis practices at a tertiary hospital. This VTE audit was conducted alongside a nurses' survey to assess current VTE prophylaxis practices. Both measures were taken to review the quality of care provided to surgical patients. Results: The practice of VTE prophylaxis shows high utilisation of all three prophylactic modalities but a lack of risk assessment documentation in the medical records. Nurses, although perceiving it as their responsibility, do not conduct assessments for venous thromboembolism risk. Conclusion: Based on the audit and survey results, the hospital has not fully adopted the guidelines for venous thromboembolism prophylaxis in major abdominal surgery cases. There is a lack of proper risk assessment documentation, and nurses are not consistently engaged in conducting these. Implications for research, policy, and practice: This paper presents valuable insights into the current prescribing practices for VTE prophylaxis after major abdominal surgery, as gleaned from a clinical audit and a survey of nurses. The hospital audit indicates that overall, all three are being used, instead of two. While this approach does not contravene current guidelines, the use of both stockings and compression devices is not needed, instead adding new risks, unnecessary nursing workload and financial cost to health services. Further, this approach may prolong recovery with patients unable to mobilise while wearing compression devices to take part in rehabilitation programs. What this paper adds: This paper adds to the existing literature by highlighting the gap between recommended guidelines and the actual implementation of VTE prophylaxis practices in the context of major abdominal surgery. These results provide meaningful clinical relevance about VTE prophylaxis practice for nurses and surgeons involved major abdominal surgery. The continuing education of Australian nurses should include an emphasis on VTE risk assessment and prevention.

Malaria prevention practices among patients attending the NTOUM departmental hospital, Northwest Gabon

Introduction: In Gabon, a territory located in Central Africa, prevention is an essential measure in the fight against malaria. The aim of this study was to evaluate, in the Komo-Mondah department, the prophylaxis practices employed by the inhabitants of the commune of Ntoum and the prevalence of anti-malarial drugs prescribed by local doctors. Methods: We carried out a prospective, cross-sectional study over a 3-month period, on patients of both sexes and of all ages who came for consultation to the departmental hospital of Ntoum. Patients who had a prescription for malaria drugs at the end of their medical visit were included in the study. Results: Of the 248 subjects enrolled, children under 5 years of age were the main victims (84%).Indeed, children under 5 were two (2) and three (3) times more likely to test positive to malaria than the age group 16-24 (OR = 2.44 [1.05 - 5.63]; P ˂ 0.05) , 25 and over (OR= 3.10 [1.46 - 6.59]; P ˂ 0.05), respectively. Anti-malaria prophylaxis was practiced by 80% of the study population. Patients who declared sleeping under a bed net appear to be protected compare to those who did not (OR= 0.53 [0.28 - 0.97] ; P ˂ 0.05). Self-medication was recorded in 29% of patients, and the drugs most commonly prescribed by doctors were artemisinin-based combinations, including Artefan (51%), Coartem (30%) and Eurartesim (2%). Conclusion: Although conventional prophylaxis measures (vector control and chemoprevention) are adopted by many Gabonese, careful pharmacological management and the implementation of targeted, long-term prevention-surveillance and health education strategies will enable effective malaria control in this part of Gabon.

(182) MULTICENTER EXAMINATION OF CONTEMPORARY PENILE PROTHESIS SURGERY INFECTION PROPHYLAXIS PRACTICES

Abstract Introduction High-level evidence to guide antimicrobial prophylaxis or irrigation solution usage in penile prosthesis surgery remains unclear. This results in variability in prophylaxis practice patterns among prosthetic urologists. Objective This study aims to investigate infection prevention prophylaxis patterns among penile prosthesis surgeons. Methods Following IRB approval, an anonymous online survey was distributed to prosthetic urologists within the Sexual Medicine Society of North America (SMSNA), the Society of Urologic Prosthetic Surgeons (SUPS), and the Society of Genitourinary Reconstructive Surgeons (GURS). The survey collected data on preoperative, perioperative, and postoperative antimicrobial prophylaxis measures. This included antibiotic types, duration, antifungal usages, implant dipping, and irrigation in a variety of common clinical scenarios. Results Of 107 responses, most respondents were male (86.9%), with 10-15 years (10.3%) or over 15 years (21.5%) of experience. The majority worked at academic centers (56.1%), and 31.8% were fellowship trained in andrology, while 49.5% were fellowship trained in reconstructive urology. For primary IPP insertion, 23.4% of surgeons prescribed oral preoperative antibiotics. The most common preoperative oral antibiotic type was trimethoprim/sulfamethoxazole (TMP/SMX) in 60.0%. Perioperative IV antibiotics were most commonly a combination of vancomycin and gentamicin dosed by weight (80 mg 6.5%, weight-based 64.5%). Implant dipping was common (61.7%), most often with vancomycin and gentamicin (34.8%). Postoperative oral antibiotics were prescribed by most surgeons (77.6%) for 6-7 days, primarily TMP/SMX (67.6%). In diabetic or immunosuppressed primary IPP insertion, preoperative antibiotics were prescribed by 28%, mostly with TMP/SMX (50.0%). All surgeons administered perioperative IV antibiotics, mainly vancomycin and gentamicin (10.3% 80 mg, 54.2% weight-based). Implant dipping was common (62.6%), most often with vancomycin and gentamicin (44.8%). Postoperative antibiotics were prescribed by most surgeons (81.3%) for 6-7 days, primarily TMP/SMX (65.5%). In revision IPP surgery, oral preoperative antibiotics were prescribed by 27.1%, with TMP/SMX a frequently selected option (51.7%). Perioperative IV antibiotics were administered by all surgeons, vancomycin and gentamicin (5.6% 80 mg and 58.9% weight-based). Implant dipping was common (63.6%), often with a combination of vancomycin and gentamicin (33.8%).Postoperative antibiotics were prescribed by most surgeons (87.9%) for 6-7 days, primarily TMP/SMX (66.0%). In salvage IPP surgery, 32.7% of surgeons prescribed preoperative oral antibiotics, mostly TMP/SMX (42.9%). Vancomycin and gentamicin (5.6% 80 mg and 50.4% weight-based) were most commonly given as IV perioperative prophylaxis. Implant dipping was common (66.4%), often with vancomycin and gentamicin (32.4%). 89.7% prescribed postoperative antibiotics, mostly for 6-7 days, primarily with TMP/SMX (58.3%). In each scenario, irrigation of the implant with 0.05% Chlorhexidine Gluconate was a common practice (range 57.9% to 60.7%). However, dipping the implant in it was less common (range 29.9% to 30.8%). Conclusions This study highlights variations in antimicrobial prophylaxis patterns among penile prosthesis surgeons. It shows prevalence of oral TMP/SMX for preoperative and postoperative oral prophylaxis, and IV vancomycin and gentamicin combination for perioperative intravenous prophylaxis. Further studies are needed to standardize IPP antimicrobial prophylaxis practices to improve patient outcomes and reduce the risk of postoperative infections.

In-hospital thromboprophylaxis variation and the risk of venous thromboembolism after lung cancer surgery: a nationwide cohort study.

Venous thromboembolic event (VTE) is a severe complication in patients with lung cancer undergoing thoracic surgery. Nevertheless, because of insufficient evidence, there are no clear guidelines, and VTE prophylaxis practices vary widely. This nationwide cohort study was a comparative study investigating VTE risk in surgical departments that routinely administered in-hospital thromboprophylaxis with low-molecular-weight heparin compared to those that did not. We identified all patients with non-small-cell lung cancer (NSCLC) who underwent surgery in Denmark during 2010-2021. Thoracic surgery was exclusively performed in the 4 university hospitals. Three hospitals implemented in-hospital thromboprophylaxis as standard care since 2000, while the fourth adopted this practice in September 2016. VTE events were assessed at 6-month follow-up according to hospital and study period, using an inverse probability of treatment weighting approach. We identified 9615 patients. During 6-month follow-up, a total of 190 VTE events were observed, resulting in a weighted rate of 4.5 events per 100 person-years and an absolute risk of 2.2%. There was no clear trend according to hospital site or use of in-hospital thromboprophylaxis with a 2.2% risk in the hospital not using thromboprophylaxis compared to 1.7-3.1% in those that did. Use of in-hospital thromboprophylaxis did not affect the risk of VTE after surgery for NSCLC, suggesting that relying solely on in-hospital thromboprophylaxis may be insufficient to mitigate VTE risk in these patients. Further research is warranted to investigate the potential benefits of extended thromboprophylaxis in reducing VTE risk in selected NSCLC surgical patients.
