Outcomes of LGBTQ culturally sensitive training among civilian and military healthcare personnel.

BACKGROUND: Lesbian, gay, bisexual, transgender, or queer (LGBTQ) military servicemembers are at higher risk of developing health problems compared to heterosexual peers. To improve outcomes and address negative attitudes, previous literature has recommended education of healthcare personnel. The purpose of our study was to evaluate the knowledge and skill outcomes of an LGBTQ cultural sensitivity training program. METHODS: We used a pretest/posttest design. Participants completed the Ally Identity Measure (AIM) to assess three subscales: knowledge and skills, openness and support, and oppression awareness. Participants included both military and civilian healthcare personnel from multiple disciplines. Descriptive statistics and pairwise analyses were used. RESULTS: A total of 101 participants answered both pretest and posttest. Across all AIM subscales, posttest scores demonstrated statistically significant (P < 0.001) increases from mean pretest scores. Completion rates for the pretest and posttest were 99% and 93%, respectively. The majority of participants were female (75%) and non-Hispanic (87%), composed of Caucasians (39%) and Asians (33%). Over one-third (39%) of participants were aged 30-39. Fifty percent were active-duty military and more than half (58%) of all participants did not have prior training in LGBTQ patient care. Statistically significant differences were found between the pretest and posttest scores for the knowledge and skills subscale (M = 2.64-3.70). The most significant increases were observed in Item 12 and Item 15 (M = 2.72-3.70) regarding awareness of theories and skill development to provide proper support, respectively. CONCLUSION: These significant findings contribute to the currently limited research exploring LGBTQ cultural sensitivity training in both civilian and military settings. To our knowledge, this is the first time a cultural sensitivity training of this depth has been provided to active-duty servicemembers. Further research and development of similar educational programs integrating interactive participation can potentially aid in the delivery of improved care and military readiness for all servicemembers.

Prevalence and Epidemiology of Mycoplasma genitalium in a Pacific-Region Military Population.

BACKGROUND: Mycoplasma genitalium is an important emerging sexually transmitted pathogen commonly causing urethritis in men, cervicitis, and pelvic inflammatory disease in women with potential of infertility. Accumulating evidence identifies the prevalence of M. genitalium similar to long recognized pathogens, Chlamydia trachomatis and Neisseria gonorrhoeae. The purpose of this study was to establish the prevalence and epidemiology of M. genitalium in a mid-Pacific military population. METHODS: A prospective analysis was conducted from routine specimens collected as standard of care for sexually transmitted infection (STI) testing at Tripler Army Medical Center on Oahu, HI. The prevalence of M. genitalium was determined using the Aptima M. genitalium assay, a transcription-mediated amplification test. A multivariate analysis was performed to assess the associations for this infection with other STIs and demographic factors. RESULTS: A total of 1876 specimens were tested in a 6-month period including 6 sample types from 1158 females and 718 males. Subject ages ranged from 18 to 76 years, with a median of 24 years (interquartile range, 21-29 years). The prevalence of M. genitalium was 8.8% overall (n = 165), 7.1% in females and 11.6% in males. Coinfection with M. genitalium occurred with another sexually-transmitted pathogen in 43 patients (18.3%), with C. trachomatis as the most common organism (n = 38). CONCLUSIONS: These data contribute to the evidence base for M. genitalium and STI screening in an active-duty military.

Ureteral injuries in colorectal surgery and the impact of laparoscopic and robotic-assisted approaches.

BACKGROUND: Ureteral injury is a feared complication in colorectal surgery that has been increasing over the past decade. Some have attributed this to an increased adoption of minimally invasive surgery (MIS), but the literature is hardly conclusive. In this study we aim to further assess the overall trend of ureteral injuries in colorectal surgery, and investigate propensity adjusted contributions from open and MIS to include robotic-assisted surgery. METHODS: This is a retrospective analysis of colorectal surgeries from 2006 to 2016 using the Nationwide Inpatient Sample (NIS) database. Multivariable logistic regression was performed to identify predisposing and protective factors. Demographics, hospital factors, and case-mix differences for open and MIS were accounted for via propensity analysis. The NIS coding structure changed in 2015, which could introduce a potential source of incongruity in complication rates over time. As a result, all statistical analyses included only the first nine years of data, or were conducted before and after the change for comparison. RESULTS: Of 514,162 colorectal surgeries identified there were 1598 ureteral injuries (0.31%). Ureteral injuries were found to be increasing through 2015 (2.3/1000 vs 3.3/1000; p < 0.001) and through the coding transition to 2016 (4.8/1000; p < 0.001). This trend was entirely accounted for by injuries made during open surgery, with decreasing injury rates for MIS over time. Adjusted odds ratio (OR) for ureteral injury with all MIS vs. open cases was 0.81 (95% CI 0.70-0.93, p = 0.003) and for robotic-assisted surgery alone versus open cases was 0.50 (95% CI 0.33-0.77, p = 0.001). CONCLUSIONS: The incidence rate of ureteral injuries during open colorectal surgery is increasing over time, but have been stable or decreasing for MIS cases. These findings hold even after using propensity score analysis. More research is needed to further delineate the impact of MIS and robotic-assisted surgery on ureteral injuries.

Usability of and Satisfaction With Vocera Wireless Communication.

Qualitative reports of hands-free communication devices highlight numerous improvements in communication. The purpose of this study was to assess both usability and satisfaction scores at approximately 1 year after the implementation of a hands-free communication device at two different large military facilities. To do this, a survey that included the System Usability Scale and questions to assess satisfaction with regard to use, quality, and user satisfaction was provided to staff at both of these facilities. System usability scores indicated moderate satisfaction (61.7 at facility A, 63.8 at facility B). User satisfaction rated highest levels of agreement with the hands-free devices as an important system and being useful (35%-37% at facility A, 46% at facility B). Scores regarding improving the quality of work (A = 12%, B = 16%); safety of patients (A = 23%, B = 29%); and ability to do their job in a timely manner (A = 23%, B = 29%) were the lowest. The results highlight the potential benefits of Vocera for improving communication within the healthcare team. Given the large percentage of staff turnover at both of these facilities, the sustained benefit of hands-free devices will require ongoing training and continued evaluation of workflow processes.

Bacterial Contamination of Military and Civilian Uniforms in an Emergency Department.

INTRODUCTION: The emergency department is a fast-paced, high-volume environment, serving patients with diverse and evolving acuities. Personnel providing direct care are continually exposed to pathogenic microorganisms from patients and everyday surfaces, to which the organisms may spread. Indeed, hospital items-such as electronic devices, stethoscopes, and staff clothing-have demonstrated high rates of contamination. Despite this, policies governing the use, disinfection, and wear of various environmental surfaces remain relaxed, vague, and/or difficult to enforce. This study aimed to examine the bacterial contamination on 2 hospital uniform types in a large military hospital within the emergency department. METHODS: Environmental sampling of military and civilian nursing staff uniforms was performed on 2 separate occasions. Emergency nurses wore hospital-provided freshly laundered scrubs on the first sampling day and home-laundered personally owned uniforms complicit with ED policy on the second sampling day. Samples were collected by impressing of contact blood agar growth medium at arrival (0 hour), 4 hours, and 8 hours of wear. Microbiological methods were used to enumerate and identify bacterial colonies. RESULTS: Bacterial contamination of personally owned uniforms was significantly higher than freshly laundered hospital-provided scrubs on 4 different sampling sites and across the span of an 8-hour workday. No significant differences were observed between military and civilian personally owned uniforms. However, several risk factors for nosocomial infection were increased in the military subgroup. DISCUSSION: Re-evaluating organizational factors (such as uniform policies) that increase the propensity for pathogenic contamination are critical for mitigating the spread and acquisition of multidrug-resistant organisms in the emergency department.

Open versus laparoscopic unilateral inguinal hernia repairs: defining the ideal BMI to reduce complications.

OBJECTIVES: Open inguinal hernia repair is felt to be a less expensive operation than a laparoscopic one. Performing open repair on patients with an obese body mass index (BMI) results in longer operative times, longer hospital stay, and complications that will potentially impose higher cost to the facility and patient. This study aims to define the ideal BMI at which a laparoscopic inguinal hernia repair will be advantageous over open inguinal hernia repair. METHODS: The NSQIP database was analyzed for (n = 64,501) complications, mortality, and operating time for open and laparoscopic inguinal hernia repairs during the time period from 2005 to 2012. Bilateral and recurrent hernias were excluded. Chi-square tests and Fisher's exact tests were used to assess associations between type of surgery and categorical variables including demographics, risk factors, and 30-day outcomes. Multivariable regression analyses were performed to determine whether odds ratios differed by level of BMI. The HCUP database was used for determining difference in cost and length of stay between open and laparoscopic procedures. RESULTS: There were 17,919 laparoscopic repairs and 46,582 open repairs in the study period. The overall morbidity (across all BMI categories) is statistically greater in the open repair group when compared to the laparoscopic group (p = 0.03). Postoperative complications (including wound disruption, failure to wean from the ventilator, and UTI) were greater in the open repair group across all BMI categories. Deep incisional surgical site infections (SSI) were more common in the overweight open repair group (p = 0.026). The return to the operating room across all BMI categories was statistically significant for the open repair group (n = 269) compared to the laparoscopic repair group (n = 70) with p = 0.003. There was no difference in the return to operating room between the BMI categories. The odds ratio (OR) was found to be statistically significant when comparing the obese category to both normal and overweight populations for the open procedure. CONCLUSION: Open hernia repairs have more complications than do laparoscopic ones; however, there does not appear to be a difference in treating obese patients with hernias using a laparoscopic approach versus an open one. One may consider using a laparoscopic approach in overweight patients (BMI 25-29.9) as there appears to be fewer deep SSI.

Restoring Volar Tilt in AO Type C2 Fractures of the Distal Radius With Unilateral External Fixation.

PURPOSE: To determine whether unilateral external fixation using a staged multiplanar reduction technique restores anatomic volar tilt in a distal radius fracture model. METHODS: We used radiographic images to obtain baseline measurements in 20 fresh-frozen cadaveric wrists. Through a standard dorsal approach to the radius, we performed osteotomies to simulate displaced AO/ASIF type C2 fractures. After placement of a unilateral external fixator, a stepwise technique of applying longitudinal traction followed by a volar translational maneuver was performed. Radiographic imaging was obtained after each step of the multiplanar reduction technique. RESULTS: Standard longitudinal traction did not restore volar tilt angles to their baseline measurements. The addition of a volar translation maneuver had a significant effect on restoring baseline volar tilt. There was a statistically significant difference in volar tilt measurements between straight longitudinal traction and volar translation. Radial inclination, radial height, and ulnar variance did not differ significantly between longitudinal traction and the addition of volar translation. CONCLUSIONS: A criticism of traditional external fixation is the inability of longitudinal ligamentotaxis to attain sagittal plane (volar tilt) reduction of the articular surface. This study demonstrates that a multiplanar reduction technique using unilateral external fixation devices on cadaveric distal radius fractures can achieve an acceptable reduction. CLINICAL RELEVANCE: External fixation of distal radius fractures may be favorable in situations where soft tissue loss, wound contamination, and comorbid medical factors preclude the use of internal fixation techniques. A multiplanar reduction technique using a unilateral external fixation device may facilitate fracture reduction in acceptable alignment.

A National Database Analysis Comparing the Nationwide Inpatient Sample and American College of Surgeons National Surgical Quality Improvement Program in Laparoscopic vs Open Colectomies: Inherent Variance May Impact Outcomes.

BACKGROUND: Clinical and administrative databases each have fundamental distinctions and inherent limitations that may impact results. OBJECTIVE: This study aimed to compare the American College of Surgeons National Surgical Quality Improvement Program and the Nationwide Inpatient Sample, focusing on the similarities, differences, and limitations of both data sets. DESIGN: All elective open and laparoscopic segmental colectomies from American College of Surgeons National Surgical Quality Improvement Program (2006-2013) and Nationwide Inpatient Sample (2006-2012) were reviewed. International Classification of Diseases, Ninth Revision, Clinical Modification coding identified Nationwide Inpatient Sample cases, and Current Procedural Terminology coding for American College of Surgeons National Surgical Quality Improvement Program. Common demographics and comorbidities were identified, and in-hospital outcomes were evaluated. SETTINGS: A national sample was extracted from population databases. PATIENTS: Data were derived from the Nationwide Inpatient Sample database: 188,326 cases (laparoscopic = 67,245; open = 121,081); and American College of Surgeons National Surgical Quality Improvement Program: 110,666 cases (laparoscopic = 54,191; open = 56,475). MAIN OUTCOME MEASURES: Colectomy data were used as an avenue to compare differences in patient characteristics and outcomes between these 2 data sets. RESULTS: Laparoscopic colectomy demonstrated superior outcomes compared with open; therefore, results focused on comparing a minimally invasive approach among the data sets. Because of sample size, many variables were statistically different without clinical relevance. Coding discrepancies were demonstrated in the rate of conversion from laparoscopic to open identified in the National Surgical Quality Improvement Program (3%) and Nationwide Inpatient Sample (15%) data sets. The prevalence of nonmorbid obesity and anemia from National Surgical Quality Improvement Program was more than twice that of Nationwide Inpatient Sample. Sepsis was statistically greater in National Surgical Quality Improvement Program, with urinary tract infections and acute kidney injury having a greater frequency in the Nationwide Inpatient Sample cohort. Surgical site infections were higher in National Surgical Quality Improvement Program (30-day) vs Nationwide Inpatient Sample (8.4% vs 2.6%; p < 0.01), albeit less when restricted to infections that occurred before discharge (3.3% vs 2.6%; p < 0.01). LIMITATIONS: This is a retrospective study using population-based data. CONCLUSION: This analysis of 2 large national databases regarding colectomy outcomes highlights the incidence of previously unrecognized data variability. These discrepancies can impact study results and subsequent conclusions/recommendations. These findings underscore the importance of carefully choosing and understanding the different population-based data sets before designing and when interpreting outcomes research.

Risk of postoperative urinary tract infections following midurethral sling operations in women undergoing hysterectomy.

INTRODUCTION AND HYPOTHESIS: Urinary tract infections (UTIs) are the most common complication following hysterectomy and mid-urethral sling procedures (MUS). As a MUS is often placed at the time of hysterectomy, we sought to determine if the addition of an MUS procedure significantly increases the risk of UTI in the first 30 days following hysterectomy. METHODS: This retrospective cohort study utilizes the National Surgical Quality Improvement Program (NSQIP) data bank for the years 2006-2012. The database collects data on all enrolled patients preoperatively and in the first 30 days postoperatively. The database was searched using procedural codes for various types of hysterectomies and MUS procedures. We assessed the incidence of postoperative UTIs following hysterectomy (HYST) only, MUS only, and hysterectomy combined with MUS (HYST + MUS). Adjusted logistic regression analyses were performed to evaluate the effects of individual risk factors and models of interaction. RESULTS: The NSQIP cohort included 3,757 in the HYST + MUS group, 9,851 in the MUS-only group, and 57,398 in the HYST-only group. The rates of postoperative UTI, which was the most common postoperative morbidity, were 5.3, 3.4, and 2.5 % respectively. Multivariate logistic regression analysis showed a persistent significant increase in rates of UTI (p < 0.001) between the MUS + HYST group and the HYST-only group. This significance was not maintained between the MUS-only group and the MUS + HYST group. CONCLUSIONS: Data from the NSQIP databank indicate that performing an MUS in combination with hysterectomy nearly doubles the risk of postoperative UTI over a hysterectomy alone.

Do the advantages of a minimally invasive approach remain in complex colorectal procedures? A nationwide comparison.

BACKGROUND: Since the introduction of laparoscopic colectomy, experience and technology continue to improve. Although accepted for many colorectal conditions, its use and outcomes in complex procedures are less understood. OBJECTIVE: The purpose of this work was to compare the perioperative outcomes of laparoscopic transverse colectomy and total abdominal colectomy (study group) with an open approach (comparative group) and the more established laparoscopic right, left, and sigmoid colectomies (control group). DESIGN: This was a retrospective review of the Nationwide Inpatient Sample (2008-2011) of all patients undergoing elective right, left, sigmoid, total, or transverse colectomy as identified by International Classification of Diseases, Ninth Revision, Clinical Modification procedure codes. Risk-adjusted 30-day outcomes were assessed using regression modeling accounting for patient characteristics, comorbidities, and surgical procedures. SETTINGS: The study included a national sample from a population database. PATIENTS: There were 45,771 admissions: 2946 in the study group, 36,949 in the control group, and 5876 in the open comparative group. MAIN OUTCOME MEASURES: Mortality was the primary outcome. Secondary outcomes included in-hospital complications, length of stay, and hospital charges. RESULTS: The patients were predominantly white (73%), had private insurance (64%), and underwent surgery at urban centers (92%). Mortality was similar between the study and control groups (0.42% vs 0.51%; p = 0.52), with a higher complication rate in the study group (19% vs 14%; p < 0.01). The study group was also associated with a lower mortality rate compared with the open group (0.51% vs 2.20%; p < 0.01), which remained consistent after adjusting for covariates (OR, 0.38 [95% CI, 0.20-0.71]; p < 0.01). The study group had fewer complications overall compared with the open group (19% vs 27%; p < 0.01) and a shorter median length of stay (4.6 vs 6.3 days; p < 0.01). LIMITATIONS: This was a retrospective study using an administrative database. CONCLUSIONS: A laparoscopic approach for total abdominal and transverse colectomies has similar mortality rates and slightly higher complications than the more established laparoscopic colectomy procedures and improved perioperative outcomes when compared with an open technique (see Video, Supplemental Digital Content 1, http://links.lww.com/DCR/A178).

Sonographic evaluation of hydronephrosis in the pediatric population: is well-tempered sonography necessary?

OBJECTIVES: Standardized protocols exist for diuretic renography. There are no specific guidelines regarding hydration before renal sonography. This study assessed the importance of the hydration status by sonographic measurements of the anteroposterior diameter and its effect on Society for Fetal Urology (SFU) hydronephrosis grading. METHODS: Children aged 6 weeks to 16 years (mean age, 22 months) with unilateral SFU grade 3 or 4 hydronephrosis requiring diuretic renal scintigraphy were recruited to undergo prehydration and posthydration renal sonography. Hydrated diuretic renal scintigraphy, or "well-tempered" renography, was then performed. Renal sonograms were reviewed by a blinded pediatric radiologist and pediatric urologist. Two-sided statistical tests assessed whether SFU grades and the anteroposterior diameter changed significantly after hydration. RESULTS: Among 67 kidneys, the pediatric urologist (L.P.M.) and pediatric radiologist (V.J.R.) reported no SFU grade change in 45 (67%) and 52 (78%) kidneys after hydration. In kidneys that changed, the posthydration grade was more likely to be higher. This difference was statistically significant (14 of 22 and 13 of 15 differences were higher grades after hydration for L.P.M. and V.J.R., respectively; P= .06; P= .007). Most kidneys that changed with hydration differed by only 1 SFU grade. Differences greater than 1 grade were seen in 5 control kidneys, which increased from SFU grade 0 to 2. The mean anteroposterior diameter increased significantly between prehydration and posthydration sonography for both hydronephrotic kidneys (1.46 versus 1.72 cm; P< .001) and control kidneys (0.22 versus 0.39 cm; P= .019), but did not correlate with increased SFU grades. CONCLUSIONS: Hydration does have a substantial effect on the anteroposterior diameter, but it does not correlate with a substantial effect on the SFU grade; therefore, well-tempered sonography seems unnecessary.

Multiplanar wrist joint proprioception: The effect of anesthetic blockade of the posterior interosseous nerve or skin envelope surrounding the joint.

STUDY DESIGN: Randomized clinical trial. PURPOSE: Contribution of the posterior interosseous nerve (PIN) and surrounding skin envelope to wrist proprioception is a topic of debate and the primary focus of this research. METHODS: We performed a double-blinded, placebo control study in which subjects underwent baseline multiplanar testing of wrist proprioception. They were randomized to receive either anesthetic blockade of the PIN within the fourth dorsal compartment, or circumferential topical anesthetic blockade of skin surrounding the wrist. Corresponding opposite wrists underwent placebo intervention with saline injection or inert ultrasound gel. Subjects repeated proprioceptive testing. RESULTS: Eighty subjects, 45 male and 35 female, mean age 33 years (range, 19-64 years), completed testing. The percentage of measurements falling outside a ±18° range did not differ between pre-treatment and post-treatment PIN blockade or for circumferential skin anesthesia. CONCLUSIONS: Wrist proprioception appears to be a multifactorial phenomenon. Surgeons may sacrifice the PIN without concern for effect on joint proprioception. LEVEL OF EVIDENCE: Level I.

Newborn pulse oximetry screening to detect critical congenital heart disease.

OBJECTIVES: To describe current practice and clarify provider opinion in the US with regard to newborn pulse oximetry screening (NPOx) for critical congenital heart disease. STUDY DESIGN: An internet-based questionnaire was forwarded to general pediatricians, neonatologists, and family medicine physicians. Physicians were surveyed regarding involvement in newborn medicine, knowledge of NPOx recommendations, and opinions regarding screening. NPOx protocol specifics were also queried. RESULTS: Survey responses (n = 481) were received with 349 respondents involved in newborn medicine. Forty-nine percent (95% CI 44%-54%) of those involved in newborn medicine practice at a hospital with a NPOx protocol. Sixty-six percent of providers endorsed it as an effective tool, 20% required more education, 11% questioned its sensitivity, and 3% had no opinion. Sixty-five percent of providers were aware of recent state legislation mandating its use and 46% reported awareness of the addition of NPOx to the Recommended Uniform Screening Panel. Eighty-four percent of providers who practice at a hospital without a NPOx protocol were interested in its implementation. NPOx protocols varied and were not uniform with differences in time of test, location of probe, and values considered positive. CONCLUSIONS: NPOx has grown in its prevalence and acceptance in clinical practice, yet is far from universal in its application and design despite the recent American Academy of Pediatrics endorsement and its addition to the Recommended Uniform Screening Panel. The majority of physicians involved in newborn medicine deemed it an effective tool.

Seasonality and Climatic Factors Associated With Human Rhinovirus/Enterovirus Nasopharyngeal Sample Positivity on Oahu, Hawai'i, 2016-2019.

INTRODUCTION: Globally, human rhinoviruses/enteroviruses (HRVs/ENTs), indistinguishable on many widely available molecular platforms, are among the leading causes of the common cold. Geographic and climatic factors impact the peak activity of these viruses. In temperate climates, the peak activity of HRV occurs during autumn and spring whereas that of ENT occurs during autumn and summer. Both viruses are thought to peak during the rainy season in tropical climates like Hawai'i; however, data remain limited. We describe HRV/ENT seasonality and evaluate the climatic factors associated with peak activity among respiratory viral samples processed on Oahu, Hawai'i. MATERIALS AND METHODS: We conducted a retrospective analysis of all respiratory specimens submitted to Tripler Army Medical Center for multiplex polymerase chain reaction testing between May 2016 and May 2019. Among HRV/ENT-positive samples, we recorded the month and year of positivity. Summative monthly positive detection was calculated with peak months above the mean. Associations between temperature, precipitation levels, relative humidity, and wind speed by week and the number of positive samples for HRV/ENT were evaluated using Poisson regression. This analysis was conducted via IRB exempt protocol number 19R18. RESULTS: During our study period, there were 7,143 nasopharyngeal respiratory samples sent for multiplex polymerase chain reaction testing, with 1,572 positive for HRV/ENT (22%). Nineteen percent of respiratory samples positive for HRV/ENT were additionally positive for one or more respiratory pathogens. The majority of HRV/ENT-positive samples arose from children < 5 years of age (n = 959, 61%). Peak months were February, March, May, August, November, and December. After controlling for lagged count and year, average wind speed was the only climatic factor significantly associated with HRV/ENT sample positivity. CONCLUSIONS: The peak monthly activity of HRV/ENT was similar to temperate climates with the exception of peak activity in February. Unlike other tropical climates, lower wind speed was associated with increased weekly HRV/ENT positivity and should be further explored as a transmission factor. Our study contributes to understanding the annual variability of HRV/ENT activity in tropical environments, which can inform clinician expectations regarding respiratory viral symptomatology in this region.

Effects of hyperglycemia and continuous intravenous insulin on outcomes of surgical patients.

BACKGROUND: Hyperglycemia in critically ill patients has been associated with increased morbidity and mortality. It is unclear to what degree hyperglycemia should be regulated in a mixed surgical population. STUDY DESIGN: A retrospective chart review of 210 surgical patients in the intensive care unit (ICU) was performed. All patients were placed on an intravenous insulin protocol targeted to a blood glucose (BG) of 80-140 mg/dL. Outcomes were compared between surgical patients with controlled BG levels (80-140 mg/dL) versus uncontrolled levels (>140 mg/dL). RESULTS: The mortality rate of this population was 12%, 5% in the controlled BG group compared with 18% in the uncontrolled BG group (P < 0.01). After adjusting for covariates, the mortality rate of the uncontrolled blood glucose group was significantly greater (OR = 4.8, 95% CI 1.4-20; P = 0.02). The overall hypoglycemic rate was <1%, and was not associated with a higher mortality, P = 0.60. A greater mortality rate was associated with patients who spent a greater time with blood glucose values >181 mg/dL (OR = 1.3, 95% CI 1.1-1.6; P = 0.01). CONCLUSIONS: Increased mortality was associated with surgical patients in the uncontrolled blood glucose group compared with patients who were well controlled with insulin therapy. These results are comparable to previous studies and indicate that surgical patients are a population who may benefit from tighter glycemic control. Further investigations through prospective randomized studies are needed to fully evaluate the effects of hyperglycemia in a diverse surgical population as well as specific surgical subspecialties.

Limited impact of an ultraviolet disinfection intervention on hygienic behaviors of nursing staff in a military hospital.

Ultraviolet disinfection (UV-C), though effective, has not been thoroughly evaluated at the level of the clinical end user. We assessed behavioral outcomes related to environmental hygiene among 60 nursing staff in a medical-surgical section after introduction of a UV-C tool aimed at disinfecting 4 high-touch surfaces, and we noted limited changes.

Pre-Pregnancy Physical Fitness, Body Mass Index and Gestational Weight Gain as Risk Factors for Cesarean Delivery: A Study of Active Duty Women.

INTRODUCTION: The World Health Organization considers the optimal rate of delivery by Cesarean among healthy nulliparous women to be <15%. In 2020, the rate of primary Cesarean delivery (CD) in the US among nulliparous women with singleton, vertex pregnancies was 26%. An enhanced understanding of factors associated with women undergoing CD may assist in reducing this rate. One potential factor is the level of physical fitness in women before pregnancy. Active duty (AD) soldiers provide a cohort of women who begin pregnancy while actively pursuing physical fitness. The research team sought to assess the effects of pre-pregnancy physical fitness of AD soldiers as measured by the Army Physical Fitness Test (APFT) on the incidence of CD in AD women, in addition to examining known demographic and pregnancy risk factors in this cohort. MATERIALS AND METHODS: We conducted a retrospective study of healthy AD nulliparous women who delivered their singleton pregnancy of >32 weeks at a tertiary medical center between 2011 and 2016. Soldiers undergoing non-labored CD were excluded. Demographics, pre-pregnancy APFT results, antepartum and labor and delivery data were collected from the Digital Training Management System, the outpatient, and inpatient medical records respectively. Weight gain in pregnancy was assessed using the Institute of Medicine Guidelines for pregnancy. Fisher's exact tests and chi-squared tests assessed associations between categorical outcomes, and unpaired t-tests assessed differences in APFT scores between women who underwent CD vs. vaginal delivery. Multivariable logistic regression analysis was used to assess for independent risk factors among all collected variables. The protocol was approved by the Regional Health Command-Pacific Institutional Review Board. RESULTS: Five-hundred-and-twenty-three women delivering singleton pregnancies between 2011 and 2016 were reviewed for this study. Three-hundred ninety women met inclusion criteria: 316 in the vaginal delivery cohort, and 74 in the CD cohort, with a CD rate of 19%. Twenty non-labored CDs were excluded. Neither total APFT performance nor performance on the individual push-up, sit-up or run events in the 15 months prior to pregnancy was associated with mode of delivery. Excessive gestational weight gain (EWG) and neonatal birth weight were the only two factors independently associated with an increased rate of cesarean delivery. Women who had excessive gestational weight gain, were twice as likely to undergo CD as those who had adequate or insufficient weight gain (24% vs. 12%, p = 0.004). Soldiers delivering a neonate ≥4,000 g were 2.8 times as likely to undergo CD as those delivering a neonate <4,000 g (47% vs. 17%, p < 0.001). Age, race, and rank, a surrogate marker for socioeconomic status, were not associated with mode of delivery. CONCLUSION: Pre-pregnancy fitness levels as measured by the APFT among healthy physically active nulliparous AD women showed no association with the incidence of labored CD. EWG is one modifiable factor which potentially increases the risk for CD in this cohort and has been documented as a risk factor in a recent metanalysis (RR-1.3). Counseling on appropriate weight gain in pregnancy may be the most effective way to reduce the rate of CD among this population of healthy and physically active women.

Effect of SARs-CoV-2 pandemic on infection prevention behaviors and bacterial burden of high touch surfaces in a medical/surgical setting.

This study aimed to determine the longitudinal efficacy of ultraviolet germicidal disinfection (UV-C) in a non-terminal disinfection context. Moreover, factors influencing enhanced infection prevention behaviors during the SARS-CoV-2 pandemic were evaluated. Sixty nursing staff from three medical/surgical wards in a large military hospital were recruited for a survey and microbiological sampling of high-touch surfaces (stethoscope, personal electronic device, common access card, and hospital ID badge) and portable medical equipment (wheelchairs and mobile commodes). Surveys included hand hygiene estimates, frequency/method of cleaning items of interest, perception of UV-C, and factors influencing the use of enhanced disinfection tools. Surveys and microbiological samples were performed prior to and after the installation of a rapid, automated ultraviolet disinfection enclosure for staff use. Both time points preceded the SARS-CoV-2 pandemic in the United States. A final survey/sampling time point was carried out eight months after the declaration of the COVID-19 pandemic. Participants' hand hygiene frequency did not increase throughout the study, with > 80% reporting a minimum of 4 hand hygiene events per patient hour. The cleaning frequency of high-touch surfaces (non-clinical) but not portable medical equipment increased after installation of a UV-C disinfection tool and was sustained eight months into the COVID-19 pandemic. While a modest decrease in bacterial burden was observed after UV-C intervention, a more significant reduction was observed across all surfaces during pandemic time sampling, though no detectable decrease in pathogenic contamination was observed at either time point. Motivators of UV-C use included fear of SARS-CoV-2 contamination and transmission, ease of device use, and access to rapid, automated disinfection tools while deterrents reported included technical concerns, lack of time, and preference for other disinfection methods. Automated, rapid-cycle UV-C disinfection can be efficacious for high-touch surfaces not currently governed by infection prevention and control guidelines. The introduction of enhanced disinfection tools like UV-C can enhance the overall cleaning frequency and is correlated with mild decreases in bacterial burden of high-touch surfaces, this is enhanced during periods of heightened infection threat. Evidence from this study offers insights into the factors which prompt healthcare workers to internalize/dismiss enhanced infection prevention procedures.

Respiratory Viral Pathogens Among U.S. Military Personnel at a Medical Treatment Facility in Hawaii From 2014 to 2019.

INTRODUCTION: Acute respiratory diseases account for a substantial number of outpatient visits and hospitalizations among U.S. military personnel, significantly affecting mission readiness and military operations. We conducted a retrospective analysis of respiratory viral pathogen (RVP) samples collected from U.S. military personnel stationed in Hawaii and tested at Tripler Army Medical Center from January 2014 to May 2019 in order to describe the etiology, distribution, and seasonality of RVP exposure in a military population. MATERIALS AND METHODS: Samples were analyzed by viral culture or multiplex PCR. Distribution of respiratory viruses over time was analyzed as well as subject demographic and encounter data. Presenting signs and symptoms were evaluated with each RVP. RESULTS: A total of 2,576 military personnel were tested, of which 726 (28.2%) were positive for one or more RVP. Among positive tests, the three most common viral pathogens detected were influenza A (43.0%), rhinovirus (24.5%), and parainfluenza (7.6%). Symptoms were generally mild and most frequently included cough, fever, and body aches. CONCLUSION: Our study evaluated respiratory virus prevalence, seasonality, and association with clinical symptoms for military personnel in an urban tropical setting in Oahu, HI, over a 5-year period. We show that viral prevalence and seasonality in Hawaii are distinct from those of the CONUS. Results contribute to the broader understanding of seasonality, clinical manifestation, and demographics of RVP among active duty military personnel stationed in Hawaii.

Incidence of postoperative intraabdominal abscesses in open versus laparoscopic appendectomies.

BACKGROUND: Risk for intraabdominal abscess (IAA) after laparoscopic appendectomy (LA) remains controversial. A 2008 Cochrane Review suggests almost a threefold increase in the incidence of IAA after LA compared with open appendectomy (OA). METHODS: The authors conducted a retrospective chart review of all appendicitis patients 18 years and older undergoing appendectomy from 1996 to 2007 at one military treatment facility and one civilian hospital in Hawaii. Data collection included demographics, procedure, presence of complicated appendicitis (defined as perforated or gangrenous appendicitis at surgical or pathologic assessment), and presence of postoperative IAA on computed axial tomography (CAT) scan. RESULTS: The review identified 2,464 patients with appendicitis. A total of 1,924 LAs (78%) and 540 OAs (22%) were performed. The comparison of laparoscopic and open appendectomies showed no significant differences in the number of postoperative abscesses (2.2% vs 1.9%; p = 0.74). The patients with a diagnosis of complicated appendicitis were significantly associated with a higher incidence of postoperative abscess formation (67% vs 25%; p < 0.01), which had an unadjusted odds ratio of 6.1 (95% confidence interval [CI], 3.4-11.0; p < 0.01). No significant difference in the development of abscess in patients with complicated appendicitis could be found between LA and OA (5.9% vs 4.1%; p = 0.44). CONCLUSIONS: No significant difference in the occurrence of IAA after LA versus OA was found. The patients with complicated appendicitis experienced a greater number of IAA than the patients with uncomplicated appendicitis.
