103 Background: Prostate biopsy is a common procedure that many U.S. men endure during their lifetime. Evidence suggests that the risk of post-biopsy infections is increasing. We aimed to characterize risk factors for post-biopsy infections using nationally representative data. Methods: We analyzed Surveillance, Epidemiology and End Results (SEER)-Medicare data to identify 246,299 male Medicare beneficiaries aged over 65 years who underwent prostate biopsy between 2001 and 2013. Multivariable logistic regression was used to assess risk factors for post-biopsy infection.The primary outcomes were any infection within 30 days of prostate biopsy, and infections requiring hospital admission within 30 days of biopsy. Results: In this cohort, 7.0% of men developed an infection within 30 days and 1.0% required hospital admission for infection. The vast majority of biopsies were performed transrectally (99.5%) without a rectal swab culture performed prior to biopsy to direct antimicrobial prophylaxis (99.7%). Risk factors for post-biopsy infection and hospitalization on multivariable analysis included age over 80 years, odds ratio (OR) 1.23 (95% confidence interval (CI) 1.17 to 1.29, for any infection, and OR 1.71 (95% CI 1.52 to 1.92) for infection requiring hospitalization, Black race, OR 1.29 (95% CI 1.23 to 1.35) for any infection, and OR 1.41 (95% CI 1.25 to 1.58) for hospitalization, and Hispanic ethnicity, OR 1.61 (95% CI 1.46 to 1.77) for any infection, and OR 1.92 (95% CI 1.52 to 2.42) for hospitalization. The risk of infection also increased with Charlson score of 3 or greater, OR 1.32 (95% CI 1.25 to 1.39), and OR 2.04 (95% CI 1.73 to 2.40) for any infection or hospitalization, respectively. High surgeon volume (>11.6 cases) was protective, OR 0.92 (95% CI 0.88 to 0.96) for any infection, and OR 0.76 (95% CI 0.69 to 0.85) for hospitalization. Conclusions: Among other factors, we identify patient age, Charlson score, race, ethnicity, and surgeon volume as significant predictors of post-prostate biopsy infection and hospitalization. These results should aid in identifying patients who may benefit from alternative techniques, such as targeted or augmented antimicrobial prophylaxis, or transperineal biopsy, to minimize this common source of morbidity.

Abstract Background Mastectomy is the most common procedure for treatment of mammary tumours. Dogs undergoing mastectomy have a risk of developing surgical site infections (SSI) and other postoperative complications. However, potential risk factors associated with such complications have been sparsely investigated. Thus, the objective of this retrospective study was to determine the incidence of, and identify risk factors for, SSI and non-SSI postoperative complications after mastectomy performed without perioperative antimicrobial prophylaxis in privately owned otherwise clinically healthy dogs. Results Medical records were reviewed retrospectively for 135 client-owned female dogs, 10–35 kg in weight and three to 10 years of age, which had undergone mastectomy due to mammary tumours at three referral animal hospitals in Sweden over a 3-year period. Twelve (8.9%) dogs developed SSI, and 21 dogs (17.1%) dogs suffered a non-SSI postoperative complication. The incidence of SSI and all complications (SSI and non-SSI) were higher in dogs that had two to three (SSI: P = 0.036 and all complications: P = 0.0039) and four to five (SSI and all complications: P = 0.038) mammary glands excised, compared to dogs that had one mammary gland excised. The incidence of SSI was 1.7% (n = 1/60) in dogs that had one gland removed. The incidence of non-SSI postoperative complications was higher in dogs with a higher body weight (P = 0.02). Conclusions The incidence of SSI was lower than or similar to previously reported incidences of SSI in dog populations that have undergone tumour excisional surgery, despite the fact that dogs in the present study had not received perioperative antibiotics. Dogs that had two or more glands excised had an increased risk of developing SSI and non-SSI complications compared to dogs that had one gland excised. Furthermore, higher BW was associated with an increased risk of non-SSI complications. Results from the study indicate that routine use of perioperative antibiotics in tumour excisional surgery can be questioned, at least in single gland mastectomy in otherwise clinically healthy dogs.

Objectives To determine if changes in public behaviours, developments in COVID-19 treatments, improved patient care, and directed policy initiatives have altered outcomes for minority ethnic groups in the second pandemic wave. Design Prospectively defined observational study using registry data. Setting Four acute NHS Hospitals in east London. Participants Patients aged ≥16 years with an emergency hospital admission with SARS-CoV-2 infection between 1st September 2020 and 17th February 2021. Main outcome measures Primary outcome was 30-day mortality from time of index COVID-19 hospital admission. Secondary endpoints were 90-day mortality and need for ICU admission. Multivariable survival analysis was used to assess associations between ethnicity and mortality accounting for predefined risk factors. Age-standardised rates of hospital admission relative to the local population were compared between ethnic groups. Results Of 5533 patients, the ethnic distribution was White (n=1805, 32.6%), Asian/Asian British (n=1983, 35.8%), Black/Black British (n=634, 11.4%), Mixed/Other (n=433, 7.8%), and unknown (n=678, 12.2%). Excluding 678 patients with missing data, 4855 were included in multivariable analysis. Relative to the White population, Asian and Black populations experienced 4.1 times (3.77-4.39) and 2.1 times (1.88-2.33) higher rates of age-standardised hospital admission. After adjustment for various patient risk factors including age, sex, and socioeconomic deprivation, Asian patients were at significantly higher risk of death within 30 days (HR 1.47 [1.24-1.73]). No association with increased risk of death in hospitalised patients was observed for Black or Mixed/Other ethnicity. Conclusions Asian and Black ethnic groups continue to experience poor outcomes following COVID-19. Despite higher-than-expected rates of admission, Black and Asian patients experienced similar or greater risk of death in hospital, implying a higher overall risk of COVID-19 associated death in these communities.

Abstract Background Little is known about risk factors for readmission after COVID-19 hospitalizations. Knowledge of these factors may help to identify patients at increased risk and may help to prevent these rehospitalizations. Methods This historical cohort study was conducted at a tertiary care academic medical center. We included COVID-19 cases diagnosed by reverse-transcriptase polymerase-chain-reaction (RT-PCR) assay between March 8th and June 14th, 2020. Patients readmitted within 30 days were identified. Using the electronic medical record, we collected data on demographic and clinical information. Data were analyzed using Student’s t-test, the chi-squared test and multivariable logistic regression. Results We included 391 patients who survived after the index hospitalization for COVID-19. The readmission rate was 13.3% (52/391). The mean time to readmission was 9.2 ± 7.9 days. The mean age (±SD) was 66.3 ± 18.6 years, 44.2% were male, and 78.8% were black/African-American. The most common presenting complaint was shortness of breath (50%). The most frequent diagnosis during the readmission was infectious process (57.7%). The mortality rate on readmission was 11.5%. Patients with a 30-day readmission were older than those not readmitted, mean age (±SD) 66.3 ± 18.6 vs. 61.0 ± 16.0, respectively (p=0.03). Readmitted patients also had a higher prevalence of heart failure and renal disease as comorbidities. Elevated alanine aminotransferase (AST) and low albumin level were also associated with readmission (Table 1). Intensive care unit (ICU) admission or mechanical ventilation during the index admission did not increase the risk of readmission. From multivariable analysis, independent predictors of 30-day readmission were higher Charlson score (p=0.004), higher creatinine on admission in the index hospitalization (p=0.009), and presence of rhabdomyolysis during the index hospitalization (p=0.039) (Table 2). Table 1. Univariable Analysis of Predictors for Readmission within 30 days from COVID-19 Infection Table 2. Multivariable Analysis of Predictors for Readmission within 30 days from COVID-19 Infection Conclusion In our cohort, infectious etiologies were common among those readmitted within 30 days of COVID-19. A higher Charlson score, acute renal failure, and rhabdomyolysis during the index admission were independent predictors of a 30-day readmission. Further studies are required to investigate these contributing factors. Disclosures All Authors: No reported disclosures

Endoscopic Dacryocystorhinostomy

Background Endoscopic dacryocystorhinostomy (EN-DCR) is an increasingly common procedure performed by otolaryngologists. While EN-DCR has a high rate of success at relieving blockage of the lacrimal system, little is known regarding associated postoperative infection (POI) rates and risk factors. Objective The purpose of this study was to identify factors associated with the occurrence of postoperative orbital and rhinologic infection in a large cohort of patients undergoing EN-DCR. Methods A retrospective review of 582 patients who underwent EN-DCR was performed. All patients received antibiotic prophylaxis as a single intraoperative intravenous administration and a ten-day postoperative oral course. Clinical and demographic information was reviewed, including the occurrence of acute orbital or rhinologic infection within 30 days of surgery. Multivariable analysis was performed to identify risk factors associated with POI. Results Fifteen of 582 patients (2.6%) developed POI following EN-DCR. The most common POI was acute rhinosinusitis (10/15, 66.7%), followed by acute dacryocystitis (2/15, 13.3%), preseptal cellulitis (2/15,13.3%), and acute bacterial conjunctivitis (1/15, 6.7%). The majority of patients (464/582, 79.7%) underwent concurrent endoscopic sinus surgery (ESS). In most cases (302/464, 65.1%), ESS was performed to address comorbid rhinosinusitis, whereas 7.8% (36/464) of patients underwent surgery to enhance surgical access to the lacrimal sac. Patients who underwent concurrent ESS were less likely to develop POI (OR: 0.17, CI: 0.04-0.80, p < 0.05). Evidence of mucopurulence at surgery increased the likelihood of POI (OR: 6.24, CI: 1.51-25.84, p < 0.05). Conclusion Mucopurulence at the time of surgery significantly increased the risk of POI, whereas concurrent ESS, performed most commonly to address comorbid rhinosinusitis, significantly decreased the risk of POI. Awareness of risk factors for POI and appropriate surgical management of concurrent rhinosinusitis can lead to reduced infectious complications after EN-DCR.

Background: Transrectal ultrasound biopsy is the preferred method for diagnosing prostate cancer, but it can cause infectious complications as a result of fluoroquinolone resistance. We aimed to explore the potential protective effect of a second rectal enema before biopsy. Methods: Between January 2015 and December 2020, 419 patients were assessed retrospectively. Patients with a history of anticoagulant use, uncontrolled diabetes, urological surgery, prostate biopsy, or recent hospitalization or overseas travel, as well as those with previous prostatitis, were excluded from the study. The patients were subsequently divided into two groups: Group 1 (n=223) had received one enema, on the morning of the biopsy, and Group 2 (n=196) had received two, with the additional enema administered half an hour before the procedure. Results: There was no significant difference between the groups in terms of age, BMI, diabetes, prostate-specific antigen (PSA) level, and prostate size (p=0.076, p=0.489, p=0.265, p=0.193, and p=0.661, respectively) or in relation to cancer detection (p=0.428). The median hospitalization date was significantly higher in Group 1 (p=0.003) as was UTI development (p=0.004). However, there was no significant difference in terms of fever and sepsis (p=0.524 and p=0.548, respectively). Additionally, subgroup analysis demonstrated that UTI was significantly lower in patients with diabetes mellitus who had received a second enema (p=0.004), though there was no significant difference in UTI between the groups in those without diabetes mellitus (p=0.215). Multivariable analysis showed that age and diabetes were significant risk factors for the development of UTI (p=0.002andp=0.003, respectively). Furthermore, the second enema was a significant protective factor for preventing UTI (p<0.001). Conclusion: Older age and the presence of diabetes mellitus are independent risk factors for UTI after prostate biopsy. A second enema procedure before biopsy may protect patients from related infectious complications and could therefore be used as an alternative preventative method.

OBJECTIVETo identify risk factors for surgical site infections (SSIs) after spine operations.DESIGNCase-control study of SSIs among patients undergoing spine operations.SETTINGAn academic health center.PATIENTSWe studied patients undergoing spinal fusions or laminectomies at the University of Iowa Hospitals and Clinics from January 1, 2007, through June 30, 2009. We included patients who acquired SSIs meeting the National Healthcare Safety Network definition. We randomly selected controls among patients who had spine operations during the study period and did not meet the SSI definition.RESULTSIn total, 54 patients acquired SSIs after 2,309 spine operations (2.3 per 100 procedures). SSIs were identified a median of 20 days after spinal fusions and 17 days after laminectomies; 90.7% were identified after discharge and 72.2% were deep incisional or organ-space infections. Staphylococcus aureus caused 53.7% of SSIs. Of patients with SSIs, 64.9% (fusion) and 70.6% (laminectomy) were readmitted and 59.5% (fusion) and 64.7% (laminectomy) underwent reoperation. By multivariable analysis, increased body mass index, Surgical Department A, fusion of 4–8 vertebrae, and operation at a thoracic or lumbar/sacral level were significant risk factors for SSIs after spinal fusions. Lack of private insurance and hypertension were significant risk factors for SSIs after laminectomies. Surgeons from Department A were more likely to use nafcillin or vancomycin for perioperative prophylaxis and to do more multilevel fusions than surgeons from Department B.CONCLUSIONSSSIs after spine operations significantly increase utilization of healthcare resources. Possible remediable risk factors include obesity, hypertension, and perioperative antimicrobial prophylaxis.Infect Control Hosp Epidemiol 2016;1458–1467

Abstract Background We created a retrospective and prospective database of SOT recipients using innovative data mining tools. This study describing the epidemiology of BSI in SOT serves as a proof of concept of such techniques in clinical research. Methods The design of the study was a retrospective, single-center, cohort study. Data mining tools were used to extract information from the electronic medical record and merged it with data from the SRTR (Figure 1). First SOT from January 1, 2010 to December 31, 2015 were included. Charts of subjects with positive blood cultures were manually reviewed and adjudicated using CDC/NHSN and SCCM/ESICM criteria. The 1-year cumulative incidence was calculated using the Kaplan–Meier method. Cox proportional hazards models were used to identify risk factors for BSI and 1-year mortality. BSI was analyzed as a time-dependent covariate in the mortality model. Fisher’s exact test and chi-square were used to identify risk factors for 30-day mortality and MDRO. Results A total of 917 SOT recipients met inclusion criteria. Seventy-five patients experienced at least one BSI. The cumulative incidence was 8.4% (95% CI 6.8–10.4) (Figure 2). The onset of the first BSI episode was: 30 episodes (40%) &lt;1 month, 33 (44%) 1–6 months, and 12 (16%) &gt;6 months. The most common pathogens were Klebsiella sp. (16%), Vancomycin-resistant E. faecium (12%), E. coli (12%), CoNS (12%), and Candida sp. (9.3%). Nineteen isolates (25%) were identified as MDRO; the risk of MDRO was highest &lt;1 month compared with 1–6 and &gt;6 months (44.8 vs. 12.1 vs. 16.7; P = 0.01). The most common source of BSI was CLABSI (29%) (Figure 3). In multivariable analysis, the risk of BSI was associated with organ type (HR [95% CI] = Multiorgan 3.5 [1.1–11.6], liver 2.5 [1.1–5.4], heart 2.4 [1.1–5.1]) and acquisition of a BSI was associated with a higher 1-year mortality (HR = 8.7 [5.1–14.7]). In univariable analysis, a polymicrobial BSI (14.7 vs. 57.1%; P = 0.02), qSOFA ≥ 2 (0.0 vs. 25.5%; P = 0.02) and septic shock (3.9 vs. 52.2%; P &lt; 0.001) were associated with an increased risk of death at 30 days. Conclusion A BSI significantly affects the 1-year survival of SOT recipients. A qSOFA ≥ 2 can be used to identify patients at risk for death. Additionally, this study illustrates the potential of data mining tools to study infectious complications. Disclosures All authors: No reported disclosures.

Abstract Background Outpatient parenteral antimicrobial therapy (OPAT) carries risk of vascular access complications, antimicrobial adverse effects, and worsening of infection. Both OPAT-related and unrelated events may lead to emergency department (ED) visits. The purpose of this study was to describe adverse events that result in ED visits and risk factors associated with ED visits during OPAT. Methods OPAT courses between January 1, 2013 and December 31, 2016 at Cleveland Clinic were identified from the institution’s OPAT registry. ED visits within 30 days of OPAT initiation were reviewed. Reasons and potential risk factors for ED visits were sought in the medical record. Results Among 11,440 OPAT courses during the study period, 603 (5%) were associated with 1 or more ED visits within 30 days of OPAT initiation. Mean patient age was 58 years and 57% were males. 379 ED visits (49%) were OPAT-related; the most common visit reason was vascular access complication, which occurred in 211 (56%) of OPAT-related ED visits. The most common vascular access complications were occlusion and dislodgement, which occurred in 99 and 34 patients (47% and 16% of vascular access complications, respectively). In a multivariable logistic regression model, at least one prior ED visit in the preceding year (prior ED visit) was most strongly associated with one or more ED visits during an OPAT course (OR 2.96, 95% CI 2.38 – 3.71, p-value &lt; 0.001). Other significant factors were younger age (p 0.01), female sex (p 0.01), home county residence (P &lt; 0.001), and having a PICC (p 0.05). 549 ED visits (71%) resulted in discharge from the ED within 24 hours, 18 (2%) left against medical advice, 46 (6%) were observed up to 24 hours, and 150 ED visits (20%) led to hospital admission. Prior ED visit was not associated with hospital admission among patients who visited the ED during OPAT. Conclusion OPAT-related ED visits are most often due to vascular access complications, especially line occlusions. Patients with a prior ED visit in the preceding year have a 3-fold higher odds of at least one ED visit during OPAT compared with patients without a prior ED visit. A strategy of managing occlusions at home and a focus on patients with prior ED visits could potentially prevent a substantial proportion of OPAT-related ED visits.

<b><i>Background:</i></b> Thromboembolic events (TEEs) may significantly complicate the clinical management of patients with testicular germ cell tumours (GCTs). We analysed a cohort of GCT patients for the occurrence of TEEs and looked to possible pathogenetic factors. <b><i>Patients, Methods:</i></b> TEEs occurring within 6 months after diagnosis were retrospectively analysed in 317 consecutive patients with testicular GCT (median age 37 years, 198 seminoma, 119 nonseminoma). The following factors were analysed for association with TEE: histology, age, clinical stage (CS), chemotherapy, use of a central venous access device (CVA). Data analysis involved descriptive statistical methods with multivariable analysis to identify independent risk factors. <b><i>Results:</i></b> Twenty-three TEEs (7.3%) were observed, 18 deep vein thromboses, 4 pulmonary embolisms, and 1 myocardial infarction. Univariable risk calculation yielded the following odds ratios (ORs) : &#x3e;CS1 OR = 43.7 (95% confidence intervals [CIs] 9.9–191.6); chemotherapy OR = 7.8 (95% CI 2.3–26.6); CVA OR = 30.5 (95% CI 11.0–84.3). Multivariable analysis identified only CS &#x3e; 1 (OR = 16.9; 95% CI 3.5–82.4) and CVA (OR = 9.0; 95% CI 2.9–27.5) as independent risk factors. <b><i>Conclusions:</i></b> Patients with CSs &#x3e;CS1 are at significantly increased risk of TEEs even without chemotherapy. Particular high risk is associated with the use of CVA devices for chemotherapy. Caregivers of GCT patients must be aware of the particular risk of TEEs.

Abstract Background Ibrutinib is a tyrosine kinase inhibitor used to treat hematologic malignancies that may increase the risk of serious infection including invasive fungal infections (IFI). In a study of 378 patients with hematologic malignancy on ibrutinib, serious infection and IFI occurred in 11% and 4% respectively (Varughese et al. Clin Infect Dis). The primary aims of our study were to determine the incidence of serious infection and associated risk factors in patients on ibrutinib. Methods We performed a retrospective analysis of patients with hematologic malignancy prescribed ibrutinib for ≥ 1 week at Yale New Haven Hospital from 2014 to 2019 to identify serious infections defined as those requiring inpatient management. We collected demographic, clinical and oncologic data. Chi-squared tests were used to determine factors associated with an increased risk of infection. Results A total of 254 patients received ibrutinib including 156 with CLL, 89 with NHL and 9 with other leukemias. Among these, 21 underwent HSCT, 9 complicated by GVHD. There were 51 (20%) patients with serious infections including 45 (17.7%) bacterial, 9 (3.5%) viral and 5 (2%) IFI (1 pulmonary cryptococcosis, 4 pulmonary aspergillosis). Anti-mold prophylaxis was prescribed to 7 (2.8%) patients, none of whom developed IFI. Risk factors associated with serious infection included ECOG score ≥ 2 (OR 4.6, p &lt; 0.001), concurrent steroid use (≥ 10 mg prednisone daily for ≥ 2 weeks; OR 3.0, p &lt; 0.001), neutropenia (OR 3.6, p &lt; 0.01), lymphopenia (OR 2.4, p &lt; 0.05) and maximum ibrutinib dose of 560 mg (OR 2, p &lt; 0.05). There was a dose dependent increase in infections based on number of chemotherapy regimens prior to ibrutinib initiation: 14.3% with 0, 19.7% with 1-2 and 28.7% with ≥ 3 prior treatments. Conclusion The incidence of serious infection in hematologic patients on ibrutinib was higher than previously reported (20% versus 11%) but the rate of IFI was lower (2% versus 4%). High ECOG score, leukopenia, steroids, and higher ibrutinib doses were associated with an increased risk for serious infection. Targeted antimicrobial prophylaxis should be considered for patients on ibrutinib with these risk factors. Improving functional status may also reduce the risk of infection in patients on ibrutinib.
