An Exploratory Study of Physician Decision-Making When Treating Uncontrolled COPD.

Purpose: Current guidelines recommend triple therapy maintenance inhalers for patients with recurrent exacerbations of chronic obstructive pulmonary disease (COPD); however, these maintenance therapies are underutilized. This study aimed to understand how physicians make COPD treatment decisions, and how combination maintenance therapies are utilized in a real-world setting. Patients and Methods: This exploratory, hypothesis-generating, non-interventional study used a cross-sectional online survey that was administered to a sample of practicing physicians in the United States. The survey included five fictitious vignettes detailing common symptoms experienced by patients with COPD. Survey questions included factors physicians consider in their decisions, and perceived barriers to prescribing treatments. Repeated measures multivariable analyses were conducted to evaluate how likely physicians were to switch to triple therapy versus no change to patient's current maintenance therapy or change to another maintenance therapy. Results: In total, 200 physicians completed the survey. Cost of treatment and patient access to treatment were reported as the most common barriers physicians consider in their prescribing decisions. Physicians were more likely to switch a patient's maintenance inhaler to triple therapy versus no change to maintenance inhaler if they considered the patient's history of new symptoms, insurance status, and clinical guidelines in their decision. Physicians with more experience treating patients with COPD, and those who treat more patients with COPD per week, were more likely to switch to triple therapy versus no change to maintenance inhaler. Conclusion: This study demonstrates the complexity of factors that can influence physicians' decisions when prescribing treatments for patients with COPD, including considerations of treatment cost, patient access and adherence, patient comorbidities, efficacy of current treatment, clinical guidelines, and provider's level of experience treating COPD. Further research may help elucidate the relative importance of the factors influencing physicians' decisions and inform what types of decision-support tools would be most beneficial.

Chronic obstructive pulmonary disease (COPD) symptoms can be effectively managed with maintenance therapies, which are treatments that are taken routinely to help improve symptoms. A combination of three different therapies (triple therapy maintenance) has been shown to be more effective than a combination of two different therapies (dual therapy maintenance) in patients with moderate-to-severe COPD. However, maintenance therapies, including triple therapy, are underutilized. This study aimed to explore how physicians make their treatment decisions for patients with COPD, and how combination maintenance therapies are utilized. To do so, we administered a survey to a sample of practicing physicians in the United States. The survey included five clinically based, fictitious profiles, or vignettes, of patients with COPD, with common symptoms and patient characteristics being described. Physicians were then asked to answer questions about what treatment they would prescribe for each patient, and any factors they considered when deciding on a treatment for a patient. We found that cost of treatment and patient access to treatment were the most common barriers that physicians considered when choosing a treatment. Physicians were also more likely to switch a patient's maintenance inhaler to a triple therapy maintenance inhaler if they considered the patient's history of new symptoms, patient's insurance status, and clinical guidelines when making their decisions. Our study shows that there are many complex factors that influence physicians' decisions when deciding on a treatment for patients with COPD.

Comparison of Healthcare Costs for Women with Treated Versus Untreated Vasomotor Symptoms Due to Menopause.

INTRODUCTION: The study objective was to estimate all-cause healthcare resource utilization (HCRU) and medical and pharmacy costs for women with treated versus untreated vasomotor symptoms (VMS) due to menopause. METHODS: A retrospective study was conducted using US claims data from Optum Research Database (study period: January 1, 2012-February 29, 2020). Women aged 40-63 years with a VMS diagnosis claim and ≥ 12 and ≥ 18 months of continuous enrollment during baseline and follow-up periods, respectively, were included. Women treated for VMS were propensity score matched 1:1 to untreated controls with VMS. Standardized differences (SDIFF) ≥ 10% were considered meaningful. A generalized linear model (gamma distribution, log link, robust standard errors) estimated the total cost of care ratio. Subgroup analyses of on- and off-label treatment costs were conducted. RESULTS: Of 117,582 women diagnosed with VMS, 20.5% initiated VMS treatment and 79.5% had no treatment. Treated women (n = 24,057) were matched to untreated VMS controls. There were no differences in HCRU at follow-up (SDIFF < 10%). Pharmacy ($487 vs $320, SDIFF 28.4%) and total ($1803 vs $1536, SDIFF 12.6%) costs were higher in the treated cohort. Total costs were 7% higher in the treated cohort (total cost ratio 1.07, 95% CI 1.05-1.10, P < 0.001). The on-label treatment pharmacy costs ($546 versus $315, SDIFF 38.6%) were higher in the treated cohort. Off-label treatment had higher medical costs ($1393 versus $1201, SDIFF 10.4%). CONCLUSIONS: Most women with VMS due to menopause were not treated within 6 months following diagnosis. While both on- and off-label treatment increased the total cost of care compared with untreated controls, those increases were modest in magnitude and should not impede treatment for women who report symptom improvement as a result of treatment.

Use of Rheumatologic Testing in Patients Who Eventually Receive a Diagnosis of Rheumatoid Arthritis.

OBJECTIVES: Anti-cyclic citrullinated peptide antibody (ACPA) has excellent specificity and prognostic value in patients with early rheumatoid arthritis (RA). The American College of Rheumatology included ACPA in their 2010 classification criteria for RA, but we hypothesize that primary care physicians (PCPs) underuse ACPA, even when clinical suspicion for RA is high. We aimed to describe their use of diagnostic testing in patients who were referred to a rheumatologist and eventually diagnosed as having RA. METHODS: In this retrospective cohort study, a systematic abstraction tool was used to review the medical records of patients seen between January 1, 2010 and June 15, 2014 in two rheumatology clinics: one private practice and one community health center associated with an academic medical center. For purposes of hypothesis generation, we compared the characteristics of patients with and without testing using unpaired t tests or Fisher exact tests. RESULTS: We identified 173 patients with RA referred from 141 different PCPs: 82.7% were women with a mean ± standard deviation age of 55.5 ± 18.6 years. ACPA and rheumatoid factor were ordered in 28.9% (95% confidence interval 22.6-36.2) and 41.0% (95% confidence interval 33.9-48.6) of patients, respectively. Imaging was underused. Almost half (45.7%, or 37/81) of the patients with documented symptom duration had a delay of at least 1 year before referral; however, ACPA utilization was not associated with the delay to treatment initiation. CONCLUSIONS: Most PCPs failed to order diagnostic tests for RA before referring a patient with polyarthritis who eventually received a diagnosis of RA. We also observed delays in diagnosis, with half of the patients waiting >1 year from symptom onset to diagnosis. These findings suggest educational efforts for PCPs should focus on emphasizing earlier diagnostic workups, especially ACPA, in patients suspected to have RA.

A Case-Control Study of Sonographic Maximum Ovarian Diameter as a Predictor of Ovarian Torsion in Emergency Department Females With Pelvic Pain.

BACKGROUND: Color and power Doppler ultrasound are commonly used in the evaluation of ovarian torsion but are unreliable. Because normal-sized ovaries are unlikely to cause torsion, maximum ovarian diameter (MOD) could theoretically be used as a screening test in the ED. Identification of MOD values below which torsion is unlikely would be of benefit to providers interpreting radiology department or point-of-care pelvic ultrasound. OBJECTIVES: The objective was to determine if sonographic MOD can be used as a screening tool to rule out torsion in selected patients. METHODS: Via a retrospective case-control study spanning a 14-year period, we examined the ultrasound characteristics of patients with torsion and age-matched controls, all presenting to the emergency department with lower abdominal pain and receiving a radiology department pelvic ultrasound for "rule-out torsion." Standardized data collection forms were utilized. Distributions of MOD were compared and sensitivity, specificity, and likelihood ratios were calculated for multiple cutoffs. RESULTS: We identified 92 cases of surgically confirmed ovarian torsion and selected 92 age-matched controls. In postmenarchal patients the sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio of 3- and 5-cm MODs were 100% (96%-100%), 30% (20%-41%), 1.4 (1.3-1.7), and 0 and 91% (83%-97%), 92% (83%-97%), 11.2 (5.5-22.9), and 0.09 (0.04-0.19), respectively. The 5-cm MOD, however, excluded an additional 52 of 84 (62%) postmenarchal patients. CONCLUSIONS: A threshold MOD of 5 cm on pelvic ultrasound may be useful to rule out ovarian torsion in postmenarchal females presenting with lower abdominal and pelvic pain.

A Predictive Model Facilitates Early Recognition of Spinal Epidural Abscess in Adults.

INTRODUCTION: Spinal epidural abscess (SEA), a highly morbid and potentially lethal deep tissue infection of the central nervous system has more than tripled in incidence over the past decade. Early recognition at the point of initial clinical presentation may prevent irreversible neurologic injury or other serious, adverse outcomes. To facilitate early recognition of SEA, we developed a predictive scoring model. METHODS: Using data from a 10-year, retrospective, case-control study of adults presenting for care at a tertiary-care, regional, academic medical center, we used the Integrated Discrimination Improvement Index (IDI) to identify candidate discriminators and created a multivariable logistic regression model, refined based on p-value significance. We selected a cutpoint that optimized sensitivity and specificity. RESULTS: The final multivariable logistic regression model based on five characteristics -patient age, fever and/or rigor, antimicrobial use within 30 days, back/neck pain, and injection drug use - shows excellent discrimination (AUC 0.88 [95% confidence interval {0.84, 0.92}]). We used the model's ß coefficients to develop a scoring system in which a cutpoint of six correctly identifies cases 89% of the time. Bootstrapped validation measures suggest this model will perform well across samples drawn from this population. CONCLUSION: Our predictive scoring model appears to reliably discriminate patients who require emergent spinal imaging upon clinical presentation to rule out SEA and should be used in conjunction with clinical judgment.

Feasibility, safety, and patient satisfaction of same-day discharge following peripheral arterial interventions: A randomized controlled study.

OBJECTIVE: To assess feasibility, safety, and patient satisfaction of same-day discharge (SD) following peripheral arterial interventions. BACKGROUND: Although diagnostic angiography is routinely performed as a same-day procedure, same-day percutaneous trans-luminal angioplasty is less common. Because there is very low incidence of peri-procedural complications after 4 hr, discharge after this window is possible provided the patient is able to ambulate and has necessary social support. To-date, safety and patient satisfaction related to SD has not been studied systematically in this population. METHOD: After providing informed consent, patients undergoing out-patient peripheral arterial interventions in a single institution between 2011 and 2015 were randomized to usual care (overnight stay, OS) or SD following successful interventions. Patient satisfaction, complications, and readmission status was ascertained by blinded telephone interviewers at 48-72 hr and 10 days post-procedure. RESULTS: A total of 24 patients consented. Of these, 5 (21.7%) failed screening, leaving 19 patients for randomization to control (n = 10) and experimental group (n = 9) conditions. The SD group experienced zero complications, however their Likert scale rating scores were significantly lower than OS for perceived level of safety (P = 0.02) and likelihood of having the procedure again (P = 0.004). CONCLUSION: This small, single-center randomized study found that among carefully selected peripheral arterial interventions, SD may be feasible and safe. However, patient satisfaction and perceived safety were significantly lower among SD compared to the OS condition. Larger prospective studies are warranted to confirm these findings.

High flow nasal oxygen therapy utilization: 7-year experience at a community teaching hospital.

OBJECTIVE: To examine the use of high flow nasal cannula oxygen therapy (HFNC) between 2008 and 2014 in patients 18 years or older at a community teaching hospital. METHODS: Yearly utilization rates of HFNC, noninvasive ventilation (NIV) and invasive mechanical ventilation (IMV) were calculated among admissions with a set of cardiopulmonary diagnoses (heart failure, COPD, asthma or pneumonia). RESULTS: Among the 41,711 admissions with at least one of the above cardiopulmonary condition, HFNC was utilized in 1,128 or 27.0/1000; NIV was used in an average of 169/1000 and IMV in 231/1000. HFNC was accompanied by IMV or NIV 71.3% of the time. From 2008 to 2014 HFNC utilization increased an average of 17.5% annually; NIV increased by 10.2% annually while IMV's utilization increased by 1.6% annually. The highest rate of change in HFNC use was among admissions with pneumonia and those with COPD. CONCLUSION: HFNC utilization increased steadily over a 7-year period at our hospital. Frequently, HFNC therapy was used in combination with other ventilatory modes to support patients' respiration. Similar with other technologies in healthcare, the uptake of HFNC has preceded the evidence from robust clinical trials.

Characteristics of Successful Internal Medicine Resident Research Projects: Predictors of Journal Publication Versus Abstract Presentation.

PURPOSE: To identify the characteristics of successful research projects at an internal medicine residency program with an established research curriculum. METHOD: The authors collected data about all research projects initiated by or involving medicine residents from 2006 to 2013 at Baystate Medical Center, using departmental files and institutional review board applications. Resident and mentor characteristics were determined using personnel files and Medline searches. Using multivariable models, the authors identified predictors of successful completion of projects using adjusted prevalence ratios (PRs). The primary outcome was manuscript publication, and secondary outcome was publication or regional/national presentation. Finally, residents were surveyed to identify barriers and/or factors contributing to project completion. RESULTS: Ninety-four research projects were identified: 52 (55.3%) projects achieved the primary outcome and 72 (76.5%) met the secondary outcome, with overlap between categories. Most study designs were cross-sectional (41; 43.6%) or retrospective cohort (30; 31.9%). After adjustment, utilization of the epidemiology/biostatistical core (PR = 2.09; 95% CI: 1.36, 3.21), established publication record of resident (PR = 1.54; 95% CI: 1.14, 2.07), and resident with U.S. medical education (PR = 1.39; 95% CI: 1.02, 1.90) were associated with successful project completion. Mentor publication record (PR = 3.13) did not retain significance because of small sample size. Most respondents (65%) cited "lack of time" as a major project barrier. CONCLUSIONS: Programs seeking to increase resident publications should consider an institutional epidemiology/biostatistical core, made available to all residency research projects, and residents should choose experienced mentors with a track record of publications.

A Multicenter Evaluation of Adherence to 4 Major Elements of the Baveno Guidelines and Outcomes for Patients With Acute Variceal Hemorrhage.

GOALS: To determine the rate of and outcomes associated with guideline adherence in the care of acute variceal hemorrhage (AVH). BACKGROUND: Four major elements of high-quality care for AVH defined by the Baveno consensus (VI) include timely endoscopy (≤12 h), antibiotics, and somatostatin analogs before endoscopy and band ligation as primary therapy for esophageal varices. STUDY: We retrospectively evaluated 239 consecutive admissions of 211 patients with AVH admitted to 2 centers in Massachusetts from 2010 to 2015. The primary outcome was 6-week mortality; secondary outcomes included treatment failure (shock, hemoglobin drop by 3 g/dL, hematemesis, death ≤5 d), length of stay, and 30-day readmission. RESULTS: Guideline adherence was variable: endoscopy ≤12 hours (79.9%), antibiotics (84.9%), band ligation (78.7%), and somatostatin analogs (90.8%). However, only 150 (62.8%) received care that was adherent to all indicated criteria. The 6-week mortality rate was 22.6%. Treatment failure occurred in 50 (21.0%) admissions. Among the 198 patients who survived to discharge, 41 (20.7%) were readmitted within 30 days. Octreotide before endoscopy was associated with a reduction in 30-day readmission (18.4% vs. 42.1%; P=0.03), whereas banding of esophageal varices was associated with a reduced risk of treatment failure (15.0% vs. 50.0%; P≤0.001). However, adherence to quality metrics did not significantly reduce the risk of death within 6 weeks. CONCLUSIONS: Adherence to quality metrics may not reduce the risk of mortality but could improve secondary outcomes of AVH. Variation in practice should be addressed through quality improvement interventions.

Radiologists' Recommendations for Additional Imaging on Inpatient CT Studies: Do Referring Physicians Follow Them?

OBJECTIVES: Studies have found that recommendations for additional imaging (RAI) accompany up to 31% of index computed tomography (CT) scans. In this study we assessed the frequency with which recommendations are accepted by the referring physician and the impact of AI on case management. METHODS: We performed a cross-sectional study of all index CT scans of the chest, abdomen, and pelvis performed on adult inpatients during a 1-month period at a tertiary medical center. Each radiology report was examined for mention of RAI. We used a standardized abstraction tool to review medical records for the indication for the RAI (related to original diagnosis vs incidental finding), the clinician's rationale for pursuing or discarding the RAI, and the impact of the AI on the inpatient treatment plan. RESULTS: Among the 430 scans reviewed, most (57.7%) were of the abdomen/pelvis. RAI was recommended in 67 cases (odds ratio [OR] 15.6%; 95% confidence interval [CI] 12.4-19.3) and AI was completed in 24 of 67 cases (35.8%). Factors associated with a recommendation for AI were the presence of an incidental finding (OR 3.5, 95% CI 1.7-6.8) and verbal communication of the result to the ordering provider (OR 2.09, 95% CI 1.23-3.5). When performed, AI altered the treatment plan 75% (18/24) of the time. Among the 43 cases in which AI was not performed, 34.1% were deferred to outpatient, 13.6% underwent alternative clinical intervention, and 13.6% were judged unnecessary by the primary team. No rationale was documented in the chart for the remaining 38.6%. CONCLUSIONS: Despite concerns about autoreferral by radiologists for AI studies, we found a lower rate than in many prior studies, which may reflect a change in clinical practice. One-third of these recommendations were implemented and verbal communication was strongly associated with the likelihood of second image ordering. In the majority of the cases, the AI affected patient management. Based on these findings, radiologists should consider calling the ordering provider to increase the likelihood that the primary team will follow their recommendations.

The association between insurance type and cost-related delay in care: a survey.

OBJECTIVES: Massachusetts has insurance rates similar to those projected under the Affordable Care Act, but many of the state's patients are insured through private insurance plans with high out-of-pocket costs. We aimed to explore the relationship between insurance type (private vs public) and delays in care due to cost, stratified by income. STUDY DESIGN: Cross-sectional study. METHODS: We conducted a study of English-speaking adults recruited from the waiting rooms of the emergency department or outpatient clinics of a large healthcare system in western Massachusetts. Our primary outcome was the association between insurance type and cost-related delay in care, stratified by income. RESULTS: Of 800 individuals approached, 619 (77%) completed the survey. Participants were 60.6% male and 40.2% white, 37.2% Hispanic, and 12.6% black. The majority (61.4%) of those surveyed had public insurance, 34.1% had private insurance, and 4.5% were uninsured. Overall, 13.3% reported delays in seeking care that were related to cost. The impact of insurance on delay of care differed significantly by income tertile (P = .02): in the middle-income group ($12,500 to <$25,000 per person annually), privately insured respondents were more likely to delay care due to cost compared with publicly insured subjects (15.6% vs 8.1%; odds ratio [OR], 4.4; 95% confidence interval [CI], 1.9-10.2, unadjusted; OR, 2.2; 95% CI, 0.9-5.8, adjusted). CONCLUSIONS: Cost-related delays in care are prevalent despite the presence of an insurance mandate. Middle-income, privately insured patients report more cost-related delays in care compared with publicly insured patients with similar incomes.

Quality of Care of Hospitalized Infective Endocarditis Patients: Report from a Tertiary Medical Center.

OBJECTIVE: There have been no recent studies describing the management and outcomes of patients with infective endocarditis (IE). PATIENTS AND METHODS: We conducted a retrospective cohort study of adult patients admitted to a tertiary medical center from 2007 to 2011 with a Duke criteria consistent discharge diagnosis of IE. We examined concordance with guideline recommendations. Outcomes included embolic events, inhospital and 1-year mortality, length of stay (LOS) and cardiac surgery. We used descriptive statistics to describe the cohort and Fisher exact and unpaired t tests to compare native valve endocarditis (NVE) with prosthetic valve endocarditis (PVE). RESULTS: Of 170 patients, definite IE was present in 135 (79.4%) and possible IE in 35 (20.6%); 74.7% had NVE, and 25.3% had PVE. Mean ± standard deviation age was 60.0 ± 17.9 years. Comparing PVE to NVE, patients with PVE were less likely to have embolic events (14.0% vs. 32.3%; P = 0.03), had shorter LOS (median 12.0 days vs. 14.0 days; P = 0.047), but they did not show a statistically significant difference in inhospital mortality (20.9% vs. 12.6%; P = 0.21). Of 170, patients 27.6% (n = 47) underwent valve surgery. Most patients received timely blood cultures and antibiotics. Guideline-recommended consults were underused, with 86.5%, 54.1%, and 47.1% of patients receiving infectious disease, cardiac surgery, and cardiology consultation, respectively. As the number of consultations increased (from 0 to 3), we observed a nonsignificant trend toward reduction in 6-month readmission and 12-month mortality. CONCLUSION: IE remains a disease with significant morbidity and mortality. There are gaps in the care of IE patients, most notably underuse of specialty consultation.

Perioperative Use of Focused Transthoracic Cardiac Ultrasound: A Survey of Current Practice and Opinion.

BACKGROUND: The advent of portable ultrasound machines in recent years has led to greater availability of focused cardiac ultrasound (FoCUS) in the perioperative and critical care setting. To our knowledge, its use in the perioperative setting among anesthesiologists remains undefined. We sought to assess the use of FoCUS by members of the Society of Cardiovascular Anesthesiologists (SCA) in clinical practice, to identify variations in its application, to outline limits to its use, and to understand the level of training of physicians using this technology. METHODS: A 26-question anonymous and voluntary online survey assessing the participants' training level with FoCUS, frequency of use, and opinions regarding incorporating it into residency training and developing a pathway to basic certification. The survey was distributed to the members of the SCA via email. RESULTS: The survey was completed by 379 of 3660 members of the SCA (10%). Of the respondents, the majority (67%) had completed a cardiovascular anesthesiology fellowship with 58% identifying their practice as academic, while 37% stated they were in private practice, and 6% were military/Veterans Administration. Most (84%) of the respondents practiced in North America. Eighty-one percent reported familiarity with FoCUS, while 47% stated they use it in their clinical practice. Those practicing in North America were significantly less likely to utilize FoCUS in their practice as compared to other respondents. With regard to training and certification, 88% believe FoCUS education should be integrated into residency training programs and 74% believe there should be a pathway to basic certification for FoCUS. CONCLUSIONS: While most cardiovascular anesthesiologists are familiar with FoCUS, a minority have integrated it into their practice. Roadblocks such as lack of training, the fear of missing diagnoses, lack of resources, and the lack of a formal certification process must be addressed to allow for more widespread use of perioperative cardiac ultrasound.

Spinal Epidural Abscess in Adults: A 10-Year Clinical Experience at a Tertiary Care Academic Medical Center.

Background. Delayed recognition of spinal epidural abscess (SEA) contributes to poor outcomes from this highly morbid and potentially lethal infection. We performed a case-control study in a regional, high-volume, tertiary care, academic medical center over the years 2005-2015 to assess the potential changing epidemiology, clinical and laboratory manifestations, and course of this disorder and to identify factors that might lead to early identification of SEA. Methods. Diagnostic billing codes consistent with SEA were used to identify inpatient admissions for abstraction. Subjects were categorized as cases or controls based on the results of spinal imaging studies. Characteristics were compared using Fisher's exact or Kruskal-Wallis tests. All P values were 2-sided with a critical threshold of <.05. Results. We identified 162 cases and 88 controls during the study period. The incidence of SEA increased from 2.5 to 8.0 per 10 000 admissions, a 3.3-fold change from 2005 to 2015 (P < .001 for the linear trend). Compared with controls, cases were significantly more likely to have experienced at least 1 previous healthcare visit or received antimicrobials within 30 days of admission; to have comorbidities of injection drug use, alcohol abuse, or obesity; and to manifest fever or rigors. Cases were also more likely to harbor coinfection at a noncontiguous site. When available, inflammatory markers were noted to be markedly elevated in cases. Focal neurologic deficits were seen with similar frequencies in both groups. Conclusions. Based on our analysis, it appears that selected factors noted at the time of clinical presentation may facilitate early recognition of SEA.

Open access colonoscopy: Critical appraisal of indications, quality metrics and outcomes.

INTRODUCTION: In an era of cost containment and measurement of value, screening for colon cancer represents a clear target for better accountability. Bundling payment is a real possibility and will likely have to rely on open-access colonoscopy (OAC). OAC is a method to allow patients to undergo endoscopy without prior evaluation by a gastroenterologist. We conducted a cross-sectional study to evaluate the indications and outcomes among patients scheduled for OAC or traditional colonoscopy at a tertiary medical center. We hypothesized that outcomes in OAC patients would be similar to those from traditional referral modes. METHOD: Using a standardized data abstraction form, we documented indications for colonoscopy, clinical outcomes (complications, emergency room visits, phone calls), and compliance with quality indicators (QI) in a random sample of 1000 patients who underwent an outpatient colonoscopy at an academic medical center in 2013. We compared baseline characteristics and outcomes between two cohorts: OAC vs. patients who were scheduled after previous evaluation by a gastroenterologist or physician assistant or non-open access colonoscopy (NOAC). RESULTS: Patients in the OAC group were more likely to be male, non-Hispanic, to be privately insured, and to have screening (vs. diagnostic) indication. However they were significantly less likely than those in the NOAC group to have a procedure performed once scheduled, (45.5% vs. 66.9%, p<0.001), due to no-show (24/178 or 13.5% vs. 60/822 or 7.3%), cancellation (56/178 or 31.5 vs. 156/822 or 19.0%), and non-compliance (9/178 or 5.1% vs. 20/822 or 2.4%). There were no clinically meaningful differences between groups with respect to outcomes such as polyp detection (35.6% OE vs. 39.5% NOE, p=0.54), postoperative call to GI practice (5.5% vs. 2.5%, p=0.41), or QI metrics such as documentation of prep quality (99.8% vs. 98.8%, p=0.24). CONCLUSION: Patients undergoing OAC are more likely to have a screening colonoscopy but with overall similar clinical outcomes and compliance with QI to patients scheduled as NOAC. OAC remains handicapped by high cancellation and no-show rates.

Operative vs Nonoperative Management of Pediatric Blunt Pancreatic Trauma: Evaluation of the National Trauma Data Bank.

BACKGROUND: Traumatic pancreatic injury is associated with significant morbidity and mortality. We evaluated the differences in outcomes among children with blunt pancreatic injuries managed operatively and nonoperatively. STUDY DESIGN: The National Trauma Data Bank was evaluated from 2002 to 2011. Patients less than18 years of age with blunt pancreatic injuries and Abbreviated Injury Scale (AIS) scores ≥ 3 were identified. Patients were divided into nonoperative (NO), operative (O), and delayed operative (DO; operation performed 48 hours or more after admission) groups. Outcomes evaluated were total length of stay (LOS), ICU use/LOS, complications, and death. Univariate comparisons were performed using Fisher's exact and Kruskal-Wallis rank tests. Multivariable analyses were performed using robust regression and logistic regression. RESULTS: There were 424 cases analyzed. Mean (± SD) age was 10.6 ± 5.3 years, and mean Injury Severity Score (ISS) was 23.4 ± 13.4. Operative groups differed by age (p = 0.002), AIS severity (p = 0.04), and concomitant head injury (p = 0.01), but were similar with regard to sex, race, and ISS. Length of stay was significantly higher in the DO group compared with the NO or O groups; the NO group had the lowest LOS (covariate-adjusted: 18.7 days vs 11.8 days, p < 0.001 and 12.6 days, p < 0.001, respectively) and infection rates (10.2% vs 1.6% and 6.2%, respectively, p = 0.04). The ICU LOS was greatest in the DO group (vs NO, p = 0.03; O, p = 0.29), as was the likelihood of ICU use (vs NO, p = 0.02; O, p = 0.75). Groups did not differ with respect to outcomes including death (p = 0.94) and overall complication rate (p = 0.63). CONCLUSIONS: Overall, children managed nonoperatively have equivalent or better outcomes when compared with operative and delayed operative management in regard to death, overall complications, LOS, ICU LOS, and ICU use.

Focused Transthoracic Cardiac Ultrasound: A Survey of Training Practices.

OBJECTIVE: The role of focused assessment by transthoracic echocardiography or focused cardiac ultrasound (FoCUS) in the perioperative setting is uncertain and evolving. To the authors' knowledge, there are no studies that evaluate the current teaching practices regarding FoCUS in US anesthesiology residencies. The authors surveyed residents and residency program directors to examine the frequency, type, and variability of instruction regarding training of FoCUS. DESIGN: A survey study. SETTING: Anesthesiology residency programs in the United States. PARTICIPANTS: All 133 Accreditation Council for Graduate Medical Education anesthesiology program directors and their residents were invited to participate in an anonymous electronic survey. MEASUREMENTS AND MAIN RESULTS: In all, 292 respondents replied to the survey, and 245 were included in the analysis. Overall response rate was 30% for program directors. The majority of the respondents were trainees (83.7%). FoCUS training was reported to be present by 36% of respondents. Respondents from institutions in which>10% of attending physicians used FoCUS were nearly 3 times as likely as those in which fewer attending physicians used FoCUS to report presence of FoCUS training program. The most common training mode is lectures with simulation (34%), followed by bedside training (31%). The most frequently reported responsible training parties were anesthesiologists (75%), followed by cardiologists (14%). Although FoCUS training is relatively rare, most respondents (187 of 205 residents and 26 of 40 program directors) said that FoCUS should be the standard in training for anesthesia residents. CONCLUSIONS: Despite the increasing availability and use of ultrasound in clinical practice, FoCUS-related use and training remain uncommon in anesthesiology. Trainees in anesthesiology are not receiving adequate instruction in FoCUS despite their desire to acquire this skill.

Mobile vitreous opacities on ocular ultrasonography are not always pathologic: a cross-sectional survey in an asymptomatic population.

BACKGROUND: Ultrasonography is often used in the evaluation of patients with ocular concerns; however, several pathologic conditions and even some age-related changes can have similar sonographic appearances. One approach that clinicians use is to assume that unilateral findings visible at normal gain are acute, whereas bilateral findings requiring high gain are chronic, especially in the elderly population. To date, no studies have systematically evaluated this assumption. OBJECTIVES: The objectives are to determine the prevalence of monocular and binocular mobile vitreous opacities (MVOs) in the vitreous chamber in an asymptomatic population at normal and high gain levels and to determine its prevalence with higher age stratifications. METHODS: We conducted a cross-sectional survey using 2-dimensional ultrasonography with a high-frequency transducer of 105 asymptomatic subjects aged 20-89 years and evaluated each subject's eyes for the presence of MVOs at both normal and high gain levels in progressive age stratifications. RESULTS: Ultrasonographic scans were obtained on 105 subjects. At normal gain levels, MVO was present in only 1 subject (0.95%; 95% confidence interval, 0.0%-5.0%). At high gain levels, MVO was present in 28.6% (30/105) of subjects. Of the subjects with MVO at high gain, 60% (18/30) had unilateral MVO. Mobile vitreous opacity was found more frequently with advancing age, being present in 23 subjects older than 59 years, compared with 7 subjects 59 years and younger (51.1% vs 11.7%, P < .001). CONCLUSIONS: Mobile vitreous opacity in the vitreous chamber visualized at high gain levels is relatively common and may not be pathologic, even if unilateral and occurring at a relatively young age.

Reappearance and treatment of penicillin-susceptible Staphylococcus aureus in a tertiary medical centre.

OBJECTIVES: The purpose of this study was to describe trends in the prevalence and treatment patterns of penicillin-susceptible Staphylococcus aureus (SA) infections. METHODS: This was a cross-sectional study of MSSA isolates from blood cultures at a tertiary-care centre between 1 January 2003 and 31 December 2012. All blood cultures positive for MSSA drawn during the study period were used to calculate the prevalence of penicillin-susceptible SA. Repeat cultures were excluded if they were isolated within 6 weeks of the index culture. The analysis was then restricted to inpatient blood cultures to assess treatment patterns. Antibiotics administered 48-96 h after the culture were analysed. RESULTS: A total of 446 blood cultures positive for MSSA were included in the analysis. There was a distinct trend showing an increase in the percentage of penicillin-susceptible SA over 10 years from 13.2% (95% CI 4.1%-22.3%) in 2003 to 32.4% (95% CI 17.3%-47.5%) in 2012 (P trend <0.001). During the study period, penicillin use for penicillin-susceptible SA bacteraemia increased from 0.0% in 2003-04 to 50.0% in 2011-12 (P trend = 0.007). CONCLUSIONS: Over a decade, there was an ∼3-fold increase in penicillin susceptibility among MSSA blood cultures at a large tertiary-care facility. Although treatment with penicillin increased over the study period, only 50% of penicillin-susceptible SA was treated with penicillin in the final study period. This study suggests that while susceptibility to penicillin appears to be returning in SA, the use of penicillin for penicillin-susceptible SA bacteraemia is low.

Heart rate response to a caudal block in children anesthetized with sevoflurane after ultrasound confirmation of placement.

INTRODUCTION: Previous studies identified decreasing heart rate (HR) as a predictor of successful caudal placement in children using halothane and isoflurane. No changes were found in HR in the one study using sevoflurane. We documented HR changes in children following a caudal block during sevoflurane anesthesia utilizing ultrasound to confirm successful caudal placement. METHODS: Seventy-one children (1-82 months) were anesthetized with sevoflurane. A caudal block was placed with confirmation by ultrasound. Four aliquots of bupivacaine 0.2% with epinephrine 5 µg · cc(-1) were administered for a total volume of 1 cc · kg(-1) with HR recorded for 4 min. The outcomes measured were HR changes from the initial baseline and during each 1-min interval. The age-related differences in HR were also analyzed. RESULTS: Heart rate change from the initial baseline after placing the caudal needle and allowing for equilibration ranged from -10.2% to +8.9% and the HR change from the baseline at the start of each aliquot injection ranged from -9.5% to +8.9%. Most participants (n = 60, 84.5%) experienced at least one HR reduction over the observation period. For patients < 36 months, the HR change ranged from -11 to +12 b · min(-1) (mean -0.3); for patients aged ≥ 36 months, the HR change ranged from -10 to +6 b · min(-1) (mean -1.1). CONCLUSIONS: Heart rate changes following a caudal block in children ≤ 82 months of age anesthetized with sevoflurane is not a reliable indicator of a successful block. Despite 100% caudal success, many children had no decrease in HR, and in those that did, the decline was of a magnitude indeterminate from beat-to-beat variability.
