Optimizing antibiotic management for patients with acute appendicitis: A quality improvement study.

BACKGROUND: To decrease surgical site infections after appendectomy for acute appendicitis, preoperative broad-spectrum antibiotics are often used in clinical practice. However, this treatment strategy has come under scrutiny because of increasing rates of antibiotic-resistant infections. METHODS: The aim of this multisite quality improvement project was to decrease the treatment of uncomplicated acute appendicitis with piperacillin-tazobactam without increasing the rate of surgical site infections. Our quality improvement intervention had 2 distinct components: (1) updating electronic health record orders to encourage preoperative administration of narrow-spectrum antibiotics and (2) educating surgeons and emergency department clinicians about selecting appropriate antibiotic therapy for acute appendicitis. Patient demographics, clinical characteristics, and outcomes were compared 6 months before and after implementation of the quality improvement intervention. RESULTS: A total of 352 laparoscopic appendectomies were performed during the 6-month preintervention period, and 369 were performed during the 6-month postintervention period. The preintervention period and postintervention period groups had similar baseline demographics, vital signs, and laboratory test values. The rate of preoperative piperacillin-tazobactam administration significantly decreased after the intervention (51.4% preintervention period vs 20.1% postintervention period, P < .001). The rate of surgical site infections was similar in both groups (superficial surgical site infections = 1.4% preintervention period vs 0.8% postintervention period, P = .50; deep surgical site infections = 1.1% preintervention period vs 0.0% postintervention period, P = .06; and organ space surgical site infections = 3.1% preintervention period vs 3.0% postintervention period, P > .99). Rates of 30-day readmission, reoperation, and Clostridioides difficile infection also did not differ between groups. CONCLUSION: Our quality improvement intervention successfully decreased piperacillin-tazobactam administration without increasing the rate of surgical site infections in patients with acute appendicitis.

Novel Prostate Biopsy Technique Using Imaging Fusion in a Patient With Absent Rectum.

INTRODUCTION: A 70-year-old male with prior total colectomy for ulcerative colitis was referred for elevated prostate specific antigen (PSA) (8.01) with PIRADS 4 lesion on magnetic resonance imaging (MRI). Described is a novel technique using pre-operative multi-parametric prostate MRI and intraoperative computed tomography (CT) 3D/3D fusion for systematic and targeted prostate biopsy in a patient lacking a rectum. TECHNICAL CONSIDERATIONS: Under general anesthesia, an ultra-low-dose (ULD) cone beam CT was performed in supine position using a robotic-armed fluoroscopy system (Artis Zeego Care+Clear, Siemens). 3D/3D auto-registration of the femoral heads and prostate from the MRI and ULD CT was performed. The prostate edges and two areas of concern were marked. Then, reduced-dose fluoroscopy-guided prostate biopsy was performed transperineally using triangulation technique. 27 prostate biopsy cores were obtained. Grade group 5 (Gleason 4+5=9) prostate cancer was identified in two cores from the targeted lesion and one core from the prostate base. The remaining twenty-four biopsies were negative for malignancy. Surgical time was 81 minutes. PSMA scan demonstrated no metastasis or lymphadenopathy. Robotic-assisted laparoscopic radical prostatectomy was performed without complications. Final pathology demonstrated T3a, grade group 5 prostate adenocarcinoma involving 10% of the prostate volume with negative surgical margins. CONCLUSION: This is the initial report of fluoroscopy-guided prostate biopsy using imaging fusion techniques in a patient without a rectum. This technique allowed precise identification of localized, very high-risk prostate cancer with over three times the number of cores, and much lower radiation dose, than typical CT-guided biopsies. Our technique could provide a new paradigm in targeted prostate biopsy.

Gel Rolls Increase Percutaneous Nephrolithotomy Radiation Exposure.

Introduction: Despite increasing interest in reducing radiation doses during endoscopic stone surgery, there is conflicting evidence as to whether percutaneous nephrolithotomy (PCNL) positioning (prone or supine) impacts radiation. We observed clinically that a patient placed prone on gel rolls had higher than expected radiation with intraoperative CT imaging and that gel rolls were visible on the coaxial imaging. We hypothesized that gel rolls directly increase radiation doses. Methods: Anthropomorphic experiments to simulate PCNL positions were performed using a robotic multiplanar fluoroscopy system (Artis Zeego Care+Clear, Siemens) and a 5-second coaxial imaging protocol (5s BODY). A fluoroscopy phantom was placed in various positions, including prone on a gel roll; prone on blankets of equal thickness; prone and supine directly on the table; and modified supine (MS) positions using a thin gel roll or rolled blanket. Impacts of C-arm direction and use of a 1 L saline bag were also evaluated. Measured dose area product (DAP) was compared for the groups. Results: Measured DAP was found to increase by 146 µGy*m2 (287%) when prone on gel rolls compared with only 62.29 (23%) when placed on blankets of equal thickness, although the model likely both overstates the relative impact and understates the absolute impact that would be seen clinically. Measured DAP between experimental groups also varied considerably despite fluoroscopy time being held constant. Conclusions: Our experiments support our hypothesis that gel rolls directly increase radiation dose, which has not been previously reported, using an anthropomorphic model. Surgeons should consider radiolucent materials for positioning to limit radiation exposure to patients and the surgical team.

Ultralow-Dose Intraoperative Computed Tomography During Endoscopic Stone Surgery: A Quality Improvement Project.

Objectives: To improve care in patients with large kidney stones using advanced intraoperative imaging techniques to reduce perioperative radiation exposure, improve stone-free rates (SFRs), and reduce the number of surgical interventions in a quality improvement project. Patients and Methods: Patients with kidney stones appropriate for percutaneous nephrolithotomy (PCNL) treatment were scheduled into a hybrid operating room for endoscopic surgery (PCNL and/or ureteroscopy) with intent to perform intraoperative CT (ICT). Imaging was performed using an Artis Zeego Care+Clear™ (Siemens) robotic-armed multiplanar fluoroscopy system with collimation to the level of the affected kidney(s). After the initial case, the proprietary CARE™ (combined applications to reduce exposure) protocol was used. When the hybrid room was unavailable, a mobile CT scanner (O-Arm; Medtronics) was used in the traditional room (n = 2). Results: Thirty-one ICTs were performed in 23 consecutive patients during endoscopic stone procedures with a median effective radiation dose of 1.39 mSv per scan, significantly less than the preoperative noncontrast CT (12.02 mSv) in the same patients (p < 0.001). Longitudinal radiation exposure associated with stone treatment significantly decreased by 83% (15.80 to 2.68 mSv, p < 0.001) compared with a similar historical PCNL cohort. Clinically significant residual stones (≥3 mm) were identified at initial ICT in eight patients (35%) and further treated in six patients. One patient had missed residual stone diagnosed 34 days after surgery, which was apparent on re-review of the ICT. Thus, final verified SFR was 87% for all stages. Mean number of procedures improved from 1.77 to 1.30 (p = 0.05) and rate of postoperative CT scans improved from 82% to 26% (p < 0.001). Conclusion: Ultralow-dose ICT was demonstrated to simultaneously improve SFR and number of staged treatments, and greatly reduce the perioperative radiation dose for our patients. The findings support the continued use of this modality to benefit all patients with large stones.

Pharmacist adjustment of preoperative antibiotic orders to the preferred preoperative antibiotic cefazolin for patients with penicillin allergy labeling.

PURPOSE: Emerging literature has detailed the safe use of cefazolin in patients with immunoglobulin E-mediated penicillin allergy labeling (PAL) such as hives and anaphylaxis. The purpose of this article is to detail efforts led by an antimicrobial stewardship pharmacist working with an interdisciplinary team to optimize preoperative antimicrobials in patients with PAL. METHODS: A pharmacist-led, interdisciplinary collaborative practice agreement (CPA) was activated in January 2020 to permit pharmacists to independently optimize preoperative antibiotics to the preferred cefazolin in patients with PAL if nonsevere or severe reactions had been reported. A patient registry was established covering the timeframe between January 8, 2020, and January 6, 2022. Reaction during surgery was assessed via 2-provider documentation, which included surgeon and anesthesiology staff documentation of any complications during the procedure related to a suspected allergic safety event. Utilization of cefazolin, clindamycin, and vancomycin for preoperative prophylaxis was monitored before and after implementation of the CPA. RESULTS: During the stated timeframe, 10,182 procedures and/or surgeries were completed on 1,572 (15.4%) patients with PAL and 659 (41.9%) patients previously reporting at least one reaction categorized as a severe reaction, which was hives for 71.2% of these patients. Of the 659 patients with PAL reporting a severe reaction, 356 received a preoperative cephalosporin (cefazolin, 98.8%; ceftriaxone, 1.2%) and tolerated it without a reported safety event, including 52 patients with PAL previously reporting anaphylaxis. An increase in preferred preoperative antimicrobial prophylaxis utilization was noted (cefazolin: 86% to 96.3%, P < 0.001; 2019 to 2021) with reductions noted in the use of nonpreferred preoperative antibiotics (clindamycin: 2.1% to 0.2%, P < 0.001; vancomycin: 3.2% to 0.4%, P < 0.001; 2019 to 2021). CONCLUSION: A pharmacist-led, interdisciplinary CPA increased preferred preoperative antimicrobial use in patients with PAL reporting severe allergic reactions, including hives and anaphylaxis, without reported safety events.

Carbon Dioxide Pyelography: A Convenient and Safe Alternative to Both Room Air and Iodinated Contrast Pyelography During Endourologic Procedures.

Introduction/Background: There are increasing reports of serious complications related to the air pyelography technique, which raise concerns about the safety of room air (RA) injection into the renal collecting system. Carbon dioxide (CO2) is much more soluble in blood than nitrogen and oxygen and thus considerably less likely to cause gas emboli. Iodinated contrast medium (ICM) is expensive, and supplies may not be as reliable as previously assumed. CO2 pyelography (CO2-P) techniques using standard fluoroscopy and digital subtraction fluoroscopy (CO2 digital subtraction pyelography [CO2-DSP]) are described. Materials and Methods: During the endourologic stone cases, 15 to 20 mL of CO2 gas was typically injected into the renal pelvis through a catheter or sheath. Imaging was usually obtained with endovascular CO2 digital subtraction angiography settings using either a traditional fluoroscopy system (TFS) or robotic arm multiplanar fluoroscopy system (RMPFS) (Artis Zeego Care+Clear®; Siemens). Results: CO2-P was performed in 22 endoscopic stone treatment cases between March 2021 and August 2022, primarily using digital subtraction settings in 20 cases. CO2-DSP overall provided higher quality images of the renal pelvis and collecting system than CO2-P, but with a relatively higher radiation dose. Following a quality intervention, fluoroscopy doses for CO2-DSP cases were decreased by 81% overall. The use of CO2-P avoided fluoroscopic or intraoperative CT (ICT) artifacts seen with intraluminal ICM. Conclusions: CO2-P allows the urologist to obtain imaging of the renal collecting system without ICM and with much lower risk of air embolism compared with RA pyelography. CO2 is a nearly cost-free alternative to ICM. Because CO2 is widely available and the technique is easy to perform, we propose that CO2-P should be favored over traditional air pyelography to improve patient safety.

Evaluation of Piperacillin-Tazobactam for Antibiotic Prophylaxis in Traumatic Grade III Open Fractures.

Background: Broad-spectrum antibiotic agents are sometimes utilized for prophylaxis of Gustilo grade III open fractures. However, this practice is not recommended by current guidelines, and it is unknown how patient outcomes are impacted. This study aimed to determine if prophylaxis with piperacillin-tazobactam (PT) results in different rates of infection versus guideline-concordant therapy (GCT). Patients and Methods: This was a single-center, retrospective cohort study of adult trauma patients with Gustilo grade III open long bone fractures admitted between January 2008 and August 2018. The primary outcome of infection (superficial or deep) at six weeks and secondary outcomes of delayed union, nonunion, Clostridioides difficile, and development of resistant organisms were abstracted from medical records. Guideline-concordant therapy was defined as a first-generation cephalosporin with or without an aminoglycoside. Univariable and multivariable analyses controlling for injury severity score (ISS) were performed. Results: One hundred twenty patients were included; 97 (81%) received PT, 23 (19%) received GCT. Common injury mechanisms were motor vehicle/motorcycle accident (57%) and falls (17%), and a majority involved a lower extremity (65%). Baseline characteristics were similar except higher median ISS in PT (14; interquartile range [IQR], 9-22) versus GCT (9; IQR, 9-14). Guideline-concordant therapy was given for a median of four (range, 2-8) days and PT for six (range, 3-11) days (p = 0.078). On univariable analysis, PT patients had more infections at six weeks (23.7% vs. 4.3%; p = 0.042), but multivariable analysis demonstrated no difference (odds ratio [OR], 5.81; 95% confidence interval [CI], 0.73-46.25; p = 0.096). Patients receiving prophylaxis with PT had a longer median length of stay at 16 days (range, 10-22) versus nine days (range, 4-16). No statistically significant differences in delayed union, non-union, Clostridioides difficile, or development of resistant organisms were observed. Conclusions: Broad-spectrum antibiotic prophylaxis with PT did not improve infection rates compared to GCT, suggesting it may not be warranted.

Development of a culturally and linguistically sensitive virtual reality educational platform to improve vaccine acceptance within a refugee population: the SHIFA community engagement-public health innovation programme.

OBJECTIVES: To combat misinformation, engender trust and increase health literacy, we developed a culturally and linguistically appropriate virtual reality (VR) vaccination education platform using community-engaged approaches within a Somali refugee community. DESIGN: Community-based participatory research (CBPR) methods including focus group discussions, interviews, and surveys were conducted with Somali community members and expert advisors to design the educational content. Co-design approaches with community input were employed in a phased approach to develop the VR storyline. PARTICIPANTS: 60 adult Somali refugees and seven expert advisors who specialise in healthcare, autism research, technology development and community engagement. SETTING: Somali refugees participated at the offices of a community-based organisation, Somali Family Service, in San Diego, California and online. Expert advisors responded to surveys virtually. RESULTS: We find that a CBPR approach can be effectively used for the co-design of a VR educational programme. Additionally, cultural and linguistic sensitivities can be incorporated within a VR educational programme and are essential factors for effective community engagement. Finally, effective VR utilisation requires flexibility so that it can be used among community members with varying levels of health and technology literacy. CONCLUSION: We describe using community co-design to create a culturally and linguistically sensitive VR experience promoting vaccination within a refugee community. Our approach to VR development incorporated community members at each step of the process. Our methodology is potentially applicable to other populations where cultural sensitivities and language are common health education barriers.

Survey of medical center employees' willingness and availability to donate blood in support of a civilian warm fresh whole blood program.

OBJECTIVES: In military settings, utilizing warm fresh whole blood (WFWB) was associated with reduced mortality; however, there are multiple challenges for administering WFWB to civilians. The authors aimed to determine barriers to hospital employees emergently donating to civilian WFWB programs. METHODS: We surveyed hospital employee willingness to donate emergently, familiarity with blood donation, and queried baseline demographics. The electronic survey was disseminated to a random sample of employees. Descriptive and univariate analyses were performed. RESULTS: Three thousand surveys were sent; 883 were returned (28 percent). The majority of respondents were female (n = 630, 71 percent). Respondent familiarity with WFWB donation included very/somewhat familiar (n = 381, 43 percent) and somewhat-not/not-at-all familiar (n = 356, 40 percent). Most were definitely or somewhat willing to emergently donate (n = 660, 75 percent). Four hundred and sixty would drive from home to donate (52 percent). The majority worked day-time shifts (n = 754, 85 percent). In regards to donation history, 366 (41 percent) had donated blood more than ten times, but 138 (16 percent) had never donated. Barriers to emergent donation were identified (55 percent), with the most common being childcare responsibilities (n = 242; 27 percent). CONCLUSIONS: Hospital employees are willing to donate WFWB emergently, but program implementation must address donor availability and logistical barriers. Future research should assess feasibility of a civilian WFWB program by determining regulatory challenges, development of a quality system for emergency donations, assessment of optimal workforce structure, potential impact to the general blood inventory, as well as patient and community perspectives regarding untested blood units.

Is Your Career Hurting You? The Ergonomic Consequences of Surgery in 701 Urologists Worldwide.

Purpose: Our objective was to seek correlations between the type, volume, and duration of surgical work performed, surgeon habits and characteristics, and the prevalence of neck and back musculoskeletal complaint and intervention across career from training to retirement. Materials and Methods: An anonymous web-based multinational survey of urologists was conducted. The primary outcome measured was pain. Secondary outcomes included pain requiring intervention and surgery. Responses were subgrouped according to geography, practice patterns, and demographics. Student t test, Fisher's exact test, and chi-square test were used for analysis. Results: A total of 701 complete responses were received from this multinational survey. Gender, pain distribution, and private or academic practice did not correlate with pain, whereas exercise, lower weight, and body mass index (BMI) were protective. Dose-response of surgical type was assessed with high- and low-volume density quartiles and frequency of each pain severity; no correlation was found. Secondary analysis showed that female practitioners seek invasive therapy less than male counterparts, and practitioners of direct optical cystoscopy report no more neck trouble than others. Length of career since residency shows little relationship to pain or pain-free rates. Conclusions: In this, the largest surgical ergonomic study to date: surgical type, duration, volume, setting, and physician gender were unrelated to surgeon pain throughout career. Exercise was associated with lower prevalence of pain in a dose-related manner; increasing weight and BMI were positively associated with pain. Although 47% of urologists with spinal pain blame their career, we are unable to identify any dose-response relationship that supports that assumption.

A Brief Provider Training Video Improves Comfort With Recommending the Human Papillomavirus Vaccine.

The American Academy of Pediatrics California Chapter 3 created a 20-minute training video targeting barriers to strong provider recommendation of the human papillomavirus (HPV) vaccine. The video included clinical vignettes featuring pediatricians modeling counseling techniques with vaccine-hesitant families. Ninety-six multidisciplinary providers (including pediatric residents) at 6 sites viewed the video and completed baseline and posttest questionnaires assessing their vaccine knowledge, attitudes toward vaccination, and comfort with skills needed to facilitate vaccination. Following the intervention, providers had substantial and statistically significant ( P < .05) improvements in multiple areas assessed, particularly knowledge of the burden of HPV-related disease in males and changes in vaccine response with age; likelihood of "strongly agreeing" that vaccination should not be delayed beyond preadolescence and that HPV vaccine is safe; and feeling "very comfortable" counseling vaccine-hesitant parents and facilitating vaccine completion. This cost-effective and easily disseminated training modality shows promise in increasing provider comfort with HPV vaccine counseling.

Prevention of Pertussis, Tetanus, and Diphtheria with Vaccines in the United States: Recommendations of the Advisory Committee on Immunization Practices (ACIP).

This report compiles and summarizes all recommendations from CDC's Advisory Committee on Immunization Practices (ACIP) regarding prevention and control of tetanus, diphtheria, and pertussis in the United States. As a comprehensive summary of previously published recommendations, this report does not contain any new recommendations and replaces all previously published reports and policy notes; it is intended for use by clinicians and public health providers as a resource. ACIP recommends routine vaccination for tetanus, diphtheria, and pertussis. Infants and young children are recommended to receive a 5-dose series of diphtheria and tetanus toxoids and acellular pertussis (DTaP) vaccines, with one adolescent booster dose of tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) vaccine. Adults who have never received Tdap also are recommended to receive a booster dose of Tdap. Women are recommended to receive a dose of Tdap during each pregnancy, which should be administered from 27 through 36 weeks' gestation, regardless of previous receipt of Tdap. After receipt of Tdap, adolescents and adults are recommended to receive a booster tetanus and diphtheria toxoids (Td) vaccine every 10 years to assure ongoing protection against tetanus and diphtheria.

Voluntarily Reported Immunization Registry Data: Reliability and Feasibility to Predict Immunization Rates, San Diego, California, 2013.

OBJECTIVES: Accurate data on immunization coverage levels are essential to public health program planning. Reliability of coverage estimates derived from immunization information systems (IISs) in states where immunization reporting by medical providers is not mandated by the state may be compromised by low rates of participation. To overcome this problem, data on coverage rates are often acquired through random-digit-dial telephone surveys, which require substantial time and resources. This project tested both the reliability of voluntarily reported IIS data and the feasibility of using these data to estimate regional immunization rates. METHODS: We matched telephone survey records for 553 patients aged 19-35 months obtained in 2013 to 430 records in the San Diego County IIS. We assessed concordance between survey data and IIS data using κ to measure the degree of nonrandom agreement. We used multivariable logistic regression models to investigate differences among demographic variables between the 2 data sets. These models were used to construct weights that enabled us to predict immunization rates in areas where reporting is not mandated. RESULTS: We found moderate agreement between the telephone survey and the IIS for the diphtheria, tetanus, and acellular pertussis (κ = 0.49), pneumococcal conjugate (κ = 0.49), and Haemophilus influenzae type b (κ = 0.46) vaccines; fair agreement for the varicella (κ = 0.39), polio (κ = 0.39), and measles, mumps, and rubella (κ = 0.35) vaccines; and slight agreement for the hepatitis B vaccine (κ = 0.17). CONCLUSIONS: Consistency in factors predicting immunization coverage levels in a telephone survey and IIS data confirmed the feasibility of using voluntarily reported IIS data to assess immunization rates in children aged 19-35 months.

Added Value of Early Literacy Screening in Preschool Children.

The Early Literacy Screener (ELS) is a brief screen for emergent literacy delays in 4- and 5-year-olds. Standard developmental screens may also flag these children. What is the value of adding the ELS? Parents of children aged 4 (n = 45) and 5 (n = 26) years completed the Ages and Stages Questionnaire-3 (ASQ-3), the Survey of Well-Being in Young Children (SWYC), and the ELS. Rates of positive agreement (PA), negative agreement (NA), and overall agreement (Cohen's κ) across the various screening tools were calculated. Early literacy delays were detected in 51% of those who passed the ASQ and 38% of those who passed the SWYC. For ELS versus ASQ, κ = 0.18, PA = 0.36 (95% CI = 0.23-0.51), and NA = 0.83 (95% CI = 0.66-0.92). For ELS versus SWYC, κ = 0.42, PA = 0.61 (95% CI = 0.45-0.75), and NA = 0.82 (95% CI = 0.65-0.92). The ELS adds value by flagging early literacy delays in many children who pass either the ASQ-3 or SWYC.

Research prioritization of men's health and urologic diseasess

ABSTRACT Objectives We sought to determine whether disease representation in the Cochrane Database of Systematic Reviews (CDSR) reflects disease burden, measured by the Global Burden of Disease (GBD) Study as disability-adjusted life-years (DALYs). Materials and Methods Two investigators performed independent assessment of ten men’s health and urologic diseases (MHUDs) in CDSR for systematic review and protocol representation, which were compared with percentage of total 2010 DALYs for the ten conditions. Data were analyzed for correlation using Spearman rank analysis. Results Nine of ten MHUDs were represented by at least one CDSR review. There was a poor and statistically insignificant positive correlation between CDSR representation and disease burden (rho = 0.42, p = 0.23). CDSR representation was aligned with disease burden for three conditions, greater than disease burden for one condition, and less than disease burden for six conditions. Conclusions These results yield high-quality estimates to inform future research prioritization for MHUDs. While prioritization processes are complex and multi-faceted, disease burden should be strongly considered. Awareness of research priority setting has the potential to minimize research disparities on a global scale.
