RESUMO
BACKGROUND: Acute kidney injury (AKI) during pregnancy is a public health problem and is associated with maternal and fetal morbidity and mortality. Clinical outcomes and health care utilization in pregnancy-related AKI, especially in women with diabetes, are not well studied. METHODS: Using data from the 2006 to 2015 Nationwide Inpatient Sample, we identified 42,190,790 pregnancy-related hospitalizations in women aged 15-49 years. We determined factors associated with AKI, including race/ethnicity, and associations between AKI and inpatient mortality, and between AKI and cardiovascular (CV) events, during pregnancy-related hospitalizations. We calculated health care expenditures from pregnancy-related AKI hospitalizations. RESULTS: Overall, the rate of AKI during pregnancy-related hospitalizations was 0.08%. In the adjusted regression analysis, a higher likelihood of AKI during pregnancy-related hospitalizations was seen in 2015 (OR 2.20; 95% CI 1.89-2.55) than in 2006; in older women aged 36-40 years (OR 1.49; 95% CI 1.36-1.64) and 41-49 years (OR 2.12; 95% CI 1.84-2.45) than in women aged 20-25 years; in blacks (OR 1.52; 95% CI 1.40-1.65) and Native Americans (OR 1.45; 95% CI 1.10-1.91) than in whites, and in diabetic women (OR 4.43; 95% CI 4.04-4.86) than in those without diabetes. Pregnancy-related hospitalizations with AKI were associated with a higher likelihood of inpatient mortality (OR 13.50; 95% CI 10.47-17.42) and CV events (OR 9.74; 95% CI 9.08-10.46) than were hospitalizations with no AKI. The median cost was higher for a delivery hospitalization with AKI than without AKI (USD 18,072 vs. 4,447). CONCLUSION: The rates of pregnancy-related AKI hospitalizations have increased during the last decade. Factors associated with a higher likelihood of AKI during pregnancy included older age, black and Native American race/ethnicity, and diabetes. Hospitalizations with pregnancy-related AKI have an increased risk of inpatient mortality and CV events, and a higher health care utilization than do those without AKI.

BACKGROUND: Pregnancy in women with ESKD undergoing dialysis is uncommon due to impaired fertility. Data on pregnancy in women on dialysis in the United States is scarce. METHODS: We evaluated a retrospective cohort of 47,555 women aged 15-44 years on dialysis between January 1, 2005 and December 31, 2013 using data from the United States Renal Data System with Medicare as primary payer. We calculated pregnancy rates and identified factors associated with pregnancy. RESULTS: In 47,555 women on dialysis, 2352 pregnancies were identified. Pregnancy rate was 17.8 per thousand person years (PTPY) with the highest rate in women aged 20-24 (40.9 PTPY). In the adjusted time-to-event analysis, a higher likelihood of pregnancy was seen in Native American (HR, 1.77; 95% CI, 1.33 to 2.36), Hispanic (HR, 1.51; 95% CI, 1.32 to 1.73), and black (HR, 1.33; 95% CI, 1.18 to 1.49) women than in white women. A higher rate of pregnancy was seen in women with ESKD due to malignancy (HR, 1.64; 95% CI, 1.27 to 2.12), GN (HR, 1.38; 95% CI, 1.21 to 1.58), hypertension (HR, 1.32; 95% CI, 1.16 to 1.51), and secondary GN/vasculitis (HR, 1.18; 95% CI, 1.02 to 1.37) than ESKD due to diabetes. A lower likelihood of pregnancy was seen among women on peritoneal dialysis than on hemodialysis (HR, 0.47; 95% CI, 0.41 to 0.55). CONCLUSIONS: The pregnancy rate is higher in women on dialysis than previous reports indicate. A higher likelihood of pregnancy was associated with race/ethnicity, ESKD cause, and dialysis modality.

BACKGROUND: Racial minorities and women constitute substantial portions of the incident and prevalent end-stage renal disease (ESRD) population in the United States. Although ESRD is characterized by high mortality, temporal trends, and race and sex differences in mortality have not been studied. METHODS: We evaluated 944,650 adult patients who initiated dialysis between January 1, 2005 and December 31, 2014, using the United States Renal Data System, for sex-related and race-related trends in mortality. Logistic regression models adjusted for pre-dialysis health status were used to examine associations among the predictors' sex, race, and year of incident dialysis, and the outcome all-cause mortality at 1-year post ESRD. RESULTS: The mean age was 65 ± 14 years. The 1-year crude mortality rates in incident ESRD patients decreased by 28% from 2004 to 2015. Risk-adjusted 1-year mortality decreased by 3% for each later year of incident ESRD (p < 0.001). In general, from 2005 to 2014, mortality rates decreased across both sexes, and all races. White patients experienced the lowest reduction in adjusted 1-year mortality rates (16%). While women experienced a survival advantage over men in 2005, by 2014 it was reversed to survival advantage for men. Combining all years, the adjusted risk of dying at 1-year after initiating dialysis was lower in women than men (OR 0.98; 95% CI 0.97-0.99), and as compared to whites, was lower in blacks (OR 0.73; 95% CI -0.72-0.74), Hispanics (OR 0.64; 95% CI 0.63-0.65), Asians (OR 0.55; 95% CI 0.53-0.56), and Native Americans (OR 0.67; 95% CI 0.63-0.71). CONCLUSION: The 1-year mortality rates among patients with ESRD have decreased steadily during a recent 10-year period across both men and women, and in all 5 races. Women have only a 2% lower risk of dying at 1-year after dialysis initiation than men. White patients had higher mortality as compared to other races. Our results suggest the need for sex, and race-specific treatment strategies in ESRD care.

BACKGROUND: Arteriovenous (AV) access confers survival benefits over central venous catheters (CVC) in hemodialysis patients. Although chronic kidney disease disproportionately affects women and racial minorities, disparities in the -utilization of hemodialysis access across Asians, Native Americans, Hispanics, blacks, and whites among males and females after accounting for pre-dialysis health are not well studied. METHODS: We evaluated 885,699 patients with end-stage renal disease who initiated hemodialysis between January 1, 2004 and December 31, 2014 using the US Renal Data System. Multivariable logistic regression models -adjusted for pre-dialysis health were used to test the associations between gender and race on type of vascular access (AV access vs. CVC, and AV fistula vs. AV graft) at hemodialysis initiation as primary outcome, and on 1-year mortality as a secondary outcome. RESULTS: Mean age was 65 ± 14 years. Females were less likely to use AV access for hemodialysis initiation than were males (OR 0.85; 95% CI 0.84-0.86). Compared to whites, adjusted odds of AV access for hemodialysis initiation were higher in blacks (OR 1.08; 95% CI 1.07-1.70), Asians (OR 1.11; 95% CI 1.07-1.14); and lower in Hispanics (OR 0.89; 95% CI 0.87-0.90). There was no -significant difference in mortality between males and females. Compared to whites, 1-year adjusted mortality was lower in Asians (OR 0.55; 95% CI 0.53-0.56), blacks (OR 0.67; 95% CI 0.66-0.68), Hispanics (OR 0.62; 95% CI 0.61-0.63), and Native Americans (OR 0.62; 95% CI 0.58-0.66). CONCLUSION: Females had lower odds of using AV access than do males for hemodialysis initiation. As compared to whites, blacks and Asians were more likely, and Hispanics were less likely to use AV access for first outpatient hemodialysis. Further investigation of biological and process of care factors may help in developing ways to reduce these disparities.

This study used the National Epidemiological Survey on Alcohol and Related Conditions, a longitudinal adult sample, to estimate the rates of prevalent, acquired, and persisting anxiety disorders by nativity and racial-ethnic origin while adjusting for acculturation, stress, social ties, and sociodemographics. Prevalent and acquired anxiety disorders were less likely among foreign-born than US-born, except Puerto-Rican- and Mexican-born who had higher risks. Persisting cases were similar between foreign-born and US-born, except Asian/Pacific Islanders who had lower risk. Stress and preference for socializing outside one's racial-ethnic group were associated with higher while close ties were associated with lower rates of acquired/persisting anxiety disorders.

BACKGROUND AND PURPOSE: Our objective was to study nationwide utilization trends of computed tomographic (CT) angiogram (CTA) and CT perfusion (CTP) in acute ischemic stroke and particularly in the context of use of reperfusion therapies. METHODS: We reviewed the Premier Perspective Database for ischemic stroke-related hospitalizations of adult patients during a 5-year period, 2006 to 2010. Use of multimodal CT-based imaging and reperfusion therapies was determined through the procedure and billing codes. Logistic regression was used to identify predictors of utilization of imaging studies and reperfusion treatments. RESULTS: An increasing proportion of ischemic strokes received CTA each year: 3.8% in 2006, 5.6% in 2007, 6.5% in 2008, 7.5% in 2009, and 9.1% in 2010 (P<0.0001). The proportion of acute strokes that were imaged with CTP imaging also increased each year: 0.05% in 2006, 0.05% in 2007, 0.9% in 2008, 2.2% in 2009, and 2.9% in 2010 (P<0.0001). Reperfusion treatment was more common among those who were imaged with CTA (13.0%) and CTP (17.6%) compared with those with CT head alone (4.0%; P<0.0001). Specifically, higher rates of recombinant tissue-type plasminogen activator were observed in CTA (10.2%) and CTP (11.4%) compared with those with CT head alone (3.8%; P<0.0001). Similarly, higher rates of mechanical embolectomy were observed in CTA (2.8%) and CTP (6.3%) compared with those with CT head alone (0.2%; P<0.0001). CONCLUSIONS: There was a marked increase in the rate of CTA and CTP studies in setting of acute ischemic stroke from 2006 to 2010, and both modalities were associated with increased reperfusion therapy use.

OBJECTIVE: Quantify the evolution and severity of neonatal skin injury, specifically diaper skin compromise, by embedding a validated skin integrity evaluation into the electronic health record (EHR). METHODS: Retrospective longitudinal cohort analysis of 747 patients stratified by gestation: 22-27, 28-31, 32-24, and 35-37 weeks, from birth to discharge. Primary outcomes were time to first perineal erythema, duration as percent days with erythema, and severity as maximum score. Data were analyzed using generalized linear models and multiple linear regression methods. RESULTS: Seventy percent had erythema and, of these, 34% had at least one high score with bleeding. Days with erythema ranged from 34-44% (p < 0.05). Days to first erythema were inversely correlated with gestational age. Risks for severe injury included short time to first erythema, 5 or more stools/day, infection, and Caucasian race/ethnicity. CONCLUSIONS: The EHR-based scale can be readily implemented to mitigate diaper skin compromise in premature infants.

BACKGROUND: Cardiovascular disease is the leading cause of mortality in patients with kidney failure, and their risk of cardiovascular events is 10 to 20 times higher as compared with the general population. METHODS AND RESULTS: We evaluated 508 822 patients who initiated dialysis between January 1, 2005 and December 31, 2014 using the United States Renal Data System with linked Medicare claims. We determined hospitalization rates for cardiovascular events, defined by acute coronary syndrome, heart failure, and stroke. We examined the association of sex with outcome of cardiovascular events, cardiovascular death, and all-cause death using adjusted time-to-event models. The mean age was 70±12 years and 44.7% were women. The cardiovascular event rate was 232 per thousand person-years (95% CI, 231-233), with a higher rate in women than in men (248 per thousand person-years [95% CI, 247-250] versus 219 per thousand person-years [95% CI, 217-220]). Women had a 14% higher risk of cardiovascular events than men (hazard ratio [HR], 1.14 [95% CI, 1.13-1.16]). Women had a 16% higher risk of heart failure (HR, 1.16 [95% CI, 1.15-1.18]), a 31% higher risk of stroke (HR, 1.31 [95% CI, 1.28-1.34]), and no difference in risk of acute coronary syndrome (HR, 1.01 [95% CI, 0.99-1.03]). Women had a lower risk of cardiovascular death (HR, 0.89 [95% CI, 0.88-0.90]) and a lower risk of all-cause death than men (HR, 0.96 [95% CI, 0.95-0.97]). CONCLUSIONS: Among patients undergoing dialysis, women have a higher risk of cardiovascular events of heart failure and stroke than men. Women have a lower adjusted risk of cardiovascular mortality and all-cause mortality.

Background: Acute kidney injury (AKI) is a major contributor to end-stage kidney disease (ESKD). About one-third of patients with ESKD due to AKI recover kidney function. However, the inability to accurately predict recovery leads to improper triage of clinical monitoring and impacts the quality of care in ESKD. Methods: Using data from the United States Renal Data System from 2005 to 2014 (n = 22 922), we developed a clinical score to predict kidney recovery within 90 days and within 12 months after dialysis initiation in patients with ESKD due to AKI. Multivariable logistic regressions were used to examine the effect of various covariates on the primary outcome of kidney recovery to develop the scoring system. The resulting logistic parameter estimates were transformed into integer point totals by doubling and rounding the estimates. Internal validation was performed. Results: Twenty-four percent and 34% of patients with ESKD due to AKI recovered kidney function within 90 days and 12 months, respectively. Factors contributing to points in the two scoring systems were similar but not identical, and included age, race/ethnicity, body mass index, congestive heart failure, cancer, amputation, functional status, hemoglobin and prior nephrology care. Three score categories of increasing recovery were formed: low score (0-6), medium score (7-9) and high score (10-12), which exhibited 90-day recovery rates of 12%, 26% and 57%. For the 12-month scores, the low, medium and high groups consisted of scores 0-5, 6-8 and 9-11, with 12-month recovery rates of 16%, 33% and 62%, respectively. The internal validation assessment showed no overfitting of the models. Conclusion: A clinical score derived from information available at incident dialysis predicts renal recovery at 90 days and 12 months in patients with presumed ESKD due to AKI. The score can help triage appropriate monitoring to facilitate recovery and begin planning long-term dialysis care for others.
RESUMO
Congregations are well positioned to address HIV in their communities, but their response to HIV has been mixed. An emerging literature describes HIV programming in urban, predominantly black congregations, but population-based data remain limited. This study examined the levels of HIV prevention and counseling programs and associated factors (e.g., religious, organizational) by using data from a phone census of congregations in the Greater Cincinnati area (N = 447). Over 10 % of congregations (36 % of Black Protestant and 5-18 % of other types of congregations) offered HIV education/prevention alone or in combination with counseling or with counseling and testing. Path analysis results showed notable significant (p < 0.05) total effects of theology-polity on HIV prevention/counseling programs, but these effects were fully mediated by other factors, including other community work and racial composition. The levels of HIV programming in this study were high by national standards, but further outreach is needed in high-risk African American communities.

INTRODUCTION: Cardiac conduction system injury is a cause of postoperative cardiac morbidity following repair of congenital heart disease (CHD). The national occurrence of postoperative complete heart block (CHB) following surgical repair of CHD is unknown. We sought to describe the occurrence of and costs related to postoperative CHB following surgical repair of common forms of CHD using a large national database. METHODS AND RESULTS: Retrospective, observational analysis performed over a 10-year period (2000-2009) using the Kids' Inpatient Database (KID). Visits for patients ≤24 months of age were identified who underwent surgical repair of ventricular septal defects (VSD), atrioventricular canal defects (AVC), and tetralogy of Fallot (TOF). Patients were identified who were diagnosed with postoperative CHB, further identifying those requiring a new pacemaker placement during the same hospitalization. Costs associated with visits were calculated. There were 16,105 surgical visits: 7,146 VSD, 3,480 AVC, and 5,480 TOF. There was a decrease in postoperative mortality (P = 0.0001) with no significant change in postoperative CHB. Hospital stay and cost were higher with CHB and placement of a permanent pacemaker. Repair of AVC (OR 1.77; [1.32-2.38]) was associated with a higher rate of postoperative CHB. Length of hospital stay and total cost were significantly increased with the development of postoperative CHB and increased further with placement of a permanent pacemaker. CONCLUSION: There has been little change over time in the frequency of postoperative CHB in patients undergoing repair of VSD, AVC, and TOF. Postoperative CHB results in major added cost to the healthcare system.

OBJECTIVE: : To document the development of geriatric psychiatry (GP) fellowship training in the United States through 2008. METHODS: : A cross-sectional survey of the 56 U.S. GP fellowship programs was conducted in summer 2007. Longitudinal data from the American Medical Association and the Association of American Medical Colleges' National Graduate Medical Education Census and data from the Accreditation Council for Graduate Medical Education were also analyzed. RESULTS: : Thirty-seven (66%) of 56 program directors responded. The number of fellowship programs has decreased over the past 7 years. During 2006/07, 72 fellows were in training, as compared with 94 fellows in 2001/02. Application rates declined significantly with a mean of 4.3 applications per program in 2006/07 as compared with the mean of 10 applications per program in 2001/02. The fill rate for first-year GP fellowship positions dropped from 61% in 2001/02 to 48% in 2006/07. During 2006/07, 67% of programs reported having two or fewer first-year fellows and 16% had no first-year fellows. Seventeen programs reported having no United States medical school graduates as first-year fellows. CONCLUSION: : The number of GP fellows in training has declined by 23% from 2001/02 to 2006/07. This decline has occurred at the same time when the number of older adults continues to expand rapidly. It is critical that an adequate number of geriatric psychiatrists be trained to support and educate general psychiatrists in the care of the elderly. Specific strategies need to be developed urgently to stimulate interest in careers in clinical and academic GP.

BACKGROUND: Syncope is a common problem in children and adolescents. The diagnostic yield for most tests commonly used in the evaluation of pediatric patients with syncope is low. STUDY OBJECTIVE: To examine the epidemiology of pediatric patients presenting to United States (US) emergency departments (EDs) with a complaint of syncope and compare their initial management to published guidelines. METHODS: ED visits from the National Hospital Ambulatory Medical Care Survey for 2003-2007 for patients aged 7-18 years were analyzed. Outcome variables were diagnostic tests and management of patients presenting with syncope. RESULTS: There were 627,489 (95% confidence interval [CI] 527,237-727,722) ED visits for syncope (0.9% of all ED visits for patients aged 7-18 years). Patients presenting to the ED for syncope were more commonly female (p<0.01), adolescent (13-18 years) (p<0.01), covered by private insurance (p=0.01), and more likely to arrive to the ED by ambulance (p<0.01), compared to those presenting with other complaints. Only 58.1% (95% CI 50.3-66.0%) of syncope patients received an electrocardiogram, and 26.5% (95% CI 18.2-34.7%) received a computed tomography (CT) or magnetic resonance imaging (MRI) scan as part of their diagnostic work-up. CONCLUSIONS: When evaluating pediatric patients presenting with syncope, there should be an increased use of the electrocardiogram to screen for underlying cardiac abnormalities. There should also be a tempered use of CT/MRI imaging in this population.

Acute antibody-mediated rejection (AMR) is mediated by the activation of the classical complement system in addition to noncomplement-dependent inflammatory pathways. Complement fixation by donor-specific antibodies leads to cleavage of the complement proteins C4, C3, and C5 to produce multiple complement split-products (CSP) and the end-effector membrane attack complex, C5b-9. In this study, we investigate CSP as potential biomarkers for AMR. Methods: In an Institutional Review Board-approved, prospective, controlled study, CSP levels were measured in blood and urine samples from consecutive kidney transplant recipients with biopsy-proven AMR (n = 10), acute cellular rejection (ACR) (n = 5), or no rejection (n = 5). After obtaining informed consent, samples were collected at the time of biopsy (day 0) and days 15 (end of rejection treatment) and 30 postbiopsy for AMR and ACR patients. ELISA was used to measure C5a, C4d, and soluble C5b-9 concentrations in blood and urine, in addition to factor Bb (Bb) concentration in blood only. Kidney transplant histopathology was evaluated using the Banff 2013 classification. Rejection treatment and follow-up were performed per standard of care. Results: Blood and urine CSP levels adjusted to urine creatinine were not elevated in AMR compared to no rejection and ACR arms. There was significant variability in CSP concentration within each of the study groups. Conclusion: Our study does not support the utility of CSP as surrogate biomarkers of AMR; however, it is limited by the small sample size and larger studies may be warranted.
RESUMO
BACKGROUND: The level of work intensity associated with patient encounters has implications for quality of care, patient safety, practice management, and reimbursement. The utility of available instruments for clinical work intensity assessment is unknown. OBJECTIVE: We assessed, in the clinical setting, the performance of existing measures of work intensity that are valid for nonclinical contexts. RESEARCH DESIGN: A cross-sectional, multimeasure design involving work intensity assessments for the last patient encounter and for an entire half-day clinic session. SUBJECTS: A convenience sample of 14 providers from the following 4 specialties: family medicine, general internal medicine, neurology, and surgery. MEASURES: Perceived clinical work intensity was measured by the following 3 instruments: National Aeronautic and Space Administration-Task Load Index, Subjective Workload Assessment Technique, and Multiple Resources Questionnaire; stress was measured by the Dundee Stress State Questionnaire. Convergent validity was assessed by correlation among the instruments. RESULTS: For the last patient encounter, there was a moderate to high correlation between the work intensity instruments' scores (Pearson's r ranged from 0.41 to 0.73) and low to moderate correlation with the distress subscale of the Dundee Stress State Questionnaire (Pearson's r ranged from -0.11 to 0.46), reflecting their stress dimension. Provider personality was associated with reported levels of work intensity and stress. Similar results were obtained when the entire clinic session was the unit of reference. CONCLUSION: Existing measures of work intensity and stress appear to be valid for use in the clinical setting to generate evidence on perceived intensity and stress experienced by providers in the performance of medical services.

BACKGROUND: Similarities and differences in physician work intensity among specialties are poorly understood but have implications for quality of care, patient safety, practice organization and management, and payment. OBJECTIVE: To determine the magnitude and important dimensions of physician work intensity for 4 specialties. RESEARCH DESIGN: Cross-sectional assessment of work intensity associated with actual patient care in the examination room or operating room. SUBJECTS: A convenience sample of 45 family physicians, 20 general internists, 22 neurologists, and 21 surgeons, located in Kansas, Kentucky, Maryland, Ohio, and Virginia. MEASURES: Work intensity measures included the National Aeronautics and Space Administration-Task Load Index (NASA-TLX), Subjective Work Assessment Technique (SWAT), and Multiple Resource Questionnaire. Stress was measured by the Dundee Stress State Questionnaire. RESULTS: Physicians reported similar magnitude of work intensity on the NASA-TLX and Multiple Resource Questionnaire. On the SWAT, general internists reported work intensity similar to surgeons but significantly lower than family physicians and neurologists (P=0.035). Surgeons reported significantly higher levels of task engagement on the stress measure than the other specialties (P=0.019), significantly higher intensity on physical demand (P < 0.001), and significantly lower intensity on the performance dimensions of the NASA-TLX than the other specialties (P=0.003). Surgeons reported the lowest intensity for temporal demand of all specialties, being significantly lower than either family physicians or neurologists (P=0.014). Family physicians reported the highest intensity on the time dimension of the SWAT, being significantly higher than either general internists or surgeons (P=0.008). CONCLUSIONS: Level of physician work intensity seems to be similar among specialties.

Alternatives and/or supplements to animal dissection are being explored by educators of human anatomy at different academic levels. Clay modeling is one such alternative that provides a kinesthetic, three-dimensional, constructive, and sensory approach to learning human anatomy. The present study compared two laboratory techniques, clay modeling of human anatomy and dissection of preserved cat specimens, in the instruction of muscles, peripheral nerves, and blood vessels. Specifically, we examined the effect of each technique on student performance on low-order and high-order questions related to each body system as well as the student-perceived value of each technique. Students who modeled anatomic structures in clay scored significantly higher on low-order questions related to peripheral nerves; scores were comparable between groups for high-order questions on peripheral nerves and for questions on muscles and blood vessels. Likert-scale surveys were used to measure student responses to statements about each laboratory technique. A significantly greater percentage of students in the clay modeling group "agreed" or "strongly agreed" with positive statements about their respective technique. These results indicate that clay modeling and cat dissection are equally effective in achieving student learning outcomes for certain systems in undergraduate human anatomy. Furthermore, clay modeling appears to be the preferred technique based on students' subjective perceptions of value to their learning experience.

The contribution of computer-aided detection (CAD) systems as an interpretive aid in screening mammography can be hampered by a high rate of false positive detections. Specificity, false positive rate, and ease of dismissing false positive marks from two CAD systems are retrospectively evaluated. One hundred screening mammographic studies with a BI-RADS assessment code of 1 or 2 and at least 2-year normal mammographic follow-up were retrospectively reviewed using two CAD systems. Breast density, CAD marks, and radiologist's ease of dismissing false positive marks were recorded. Specificities from the two CAD versions considering all marks were 23% and 15% (p value = 0.07); mass marks, 35% and 17% (p value < 0.01); and calcification marks 62% and 75% (p value = 0.01). The two CAD versions did not differ regarding mean and median marks per case for all marks (2.3, 2.0 and 2.3, 2.0, p value = 0.65) or mass marks (1.6, 1.0 and 1.8, 2.0, p value = 0.15), but differed for calcification marks (0.8, 0 and 0.5, 0, p value < 0.01). Slightly higher specificity and fewer marks per case observed in dense breasts did not reach statistical significance. The reviewing radiologist classified most marks from both CAD systems (84% and 88%) as very easy/easy to dismiss. The two CAD versions had small differences in specificity and false positive marks. Differences, although not statistically significant, in specificities and false positive rates between dense and non-dense breasts warrant further research. Most false positive marks are easily dismissed and should not affect clinical performance.

The education mission of the Department of Veterans Affairs (VA) is to train health professionals to benefit VA and the United States. One approach for achieving that mission, along with VA's research and clinical missions, was the establishment of Geriatric Research, Education and Clinical Centers (GRECCs) in 1975. These were developed at VA hospital sites that had existing strong partnerships with schools of medicine already engaged in research on aging. GRECCs were funded to enhance those research enterprises, to expand health professions education in geriatrics, to expand interest in geriatrics among medical faculty and to support them to become more expert in geriatrics, to develop new approaches to care of the aging, and to disseminate the lessons learned within VA and beyond. Using 2001 and 2008 data from two surveys of U.S. medical schools' geriatrics programs, this article explores the impact of GRECCs on geriatric programs at their affiliated schools of medicine. It demonstrates how VA's academic mission through GRECCs has benefited VA and its affiliates and how it has benefited the nation through the growth of geriatric medicine as an academic enterprise and a legitimate clinical specialty.

INTRODUCTION: We determined the rate of cystoscopy with hydrodistention (CH) before and after the 2011 American Urological Association (AUA) amended clinical guideline, "Diagnosis and Treatment of Interstitial Cystitis/Bladder Pain Syndrome." METHODS: Clinical encounters with a diagnosis of interstitial cystitis/bladder pain syndrome (IC/BPS) where cystoscopy with and without hydrodistention was performed were identified in the Vizient® Clinical Data Base between January 2009 and February 2020. Demographic and clinical information such as patient age, gender, race, treating physician specialty, insurance type and type of hospital (teaching vs nonteaching) was recorded. Descriptive statistics, Wilcoxon 2-sample test and chi-square test were used to compare variables. An interrupted time series analysis was used to assess the change in CH rate following the June 2011 AUA guideline. RESULTS: From January 2009 to February 2020, 69,983 encounters were identified to have an IC/BPS diagnosis and to have undergone outpatient cystoscopy, of which 7,502 (10.7%) were CH. Compared to those not undergoing CH, subjects with IC/BPS undergoing CH were younger, predominantly female, Caucasian and had commercial insurance. Before the guideline, across all medical specialties, the base rate of CH was rising from 16.6% at a rate of 0.12% per month. Following guideline release, the CH rate dropped by 6.8%, declining 0.07% per month until February 2020. This pattern was most pronounced in urology relative to all other medical specialties. CONCLUSIONS: The monthly average rate of CH among individuals with IC/BPS undergoing an outpatient CH dropped from nearly 17% before the 2011 AUA guideline to less than 10% in early 2020.
