RESUMO
OBJECTIVE: Guidelines from the Society for Vascular Surgery and the Choosing Wisely campaign recommend that peripheral vascular interventions (PVIs) be limited to claudication patients with lifestyle-limiting symptoms only after a failed trial of medical and exercise therapy. We sought to explore practice patterns and physician characteristics associated with early PVI after a new claudication diagnosis to evaluate adherence to these guidelines. METHODS: We used 100% Medicare fee-for-service claims to identify patients diagnosed with claudication for the first time between 2015 and 2017. Early PVI was defined as an aortoiliac or femoropopliteal PVI performed within 6 months of initial claudication diagnosis. A physician-level PVI utilization rate was calculated for physicians who diagnosed >10 claudication patients and performed at least one PVI (regardless of indication) during the study period. Hierarchical multivariable logistic regression was used to identify physician-level factors associated with early PVI. RESULTS: Of 194,974 patients who had a first-time diagnosis of claudication during the study period, 6286 (3.2%) underwent early PVI. Among the 5664 physicians included in the analysis, the median physician-level early PVI rate was low at 0% (range, 0%-58.3%). However, there were 320 physicians (5.6%) who had an early PVI rate ≥14% (≥2 standard deviations above the mean). After accounting for patient characteristics, a higher percentage of services delivered in ambulatory surgery center or office settings was associated with higher PVI utilization (vs 0%-22%; 23%-47%: adjusted odds ratio [aOR], 1.23; 48%-68%: aOR, 1.49; 69%-100%: aOR, 1.72; all P < .05). Other risk-adjusted physician factors independently associated with high PVI utilization included male sex (aOR, 2.04), fewer years in practice (vs ≥31 years; 11-20 years: aOR, 1.23; 21-30 years: aOR, 1.13), rural location (aOR, 1.25), and lower volume claudication practice (vs ≥30 patients diagnosed during study period; ≤17 patients: aOR, 1.30; 18-29 patients: aOR, 1.35; all P < .05). CONCLUSIONS: Outlier physicians with a high early PVI rate for patients newly diagnosed with claudication are identifiable using a claims-based practice pattern measure. Given the shared Society for Vascular Surgery and Choosing Wisely initiative goal to avoid interventions for first-line treatment of claudication, confidential data-sharing programs using national benchmarks and educational guidance may be useful to address high utilization in the management of claudication.

BACKGROUND: The risk assessment profile (RAP) score has been used to determine patients who would most benefit from lower extremity duplex ultrasound screening (LEDUS). We hypothesized that revising our LEDUS protocol to perform screening ultrasound examinations in patients with an RAP ≥8 within 48 h of admission would reduce the number of LEDUS performed without changing outcomes. METHODS: A retrospective review was conducted on trauma patients admitted from July 1, 2014, to June 30, 2015, and July 1, 2016, to June 30, 2017. In 2014-2015, patients with an RAP score ≥5 underwent weekly LEDUS examinations starting on hospital day 4. In 2016-2017, the protocol was changed to start screening patients with an RAP score ≥8 by hospital day 2. Both protocols screened with weekly ultrasounds after the first examination. Demographic data, injury characteristics, LEDUS examination findings, chemoprophylaxis type, and venous thromboembolism incidence were collected. RESULTS: A total of 602 patients underwent LEDUS examination in 2014-2015, whereas only 412 underwent LEDUS in 2016-2017. No significant difference was seen in the number of patients diagnosed with deep vein thrombosis (DVT) or pulmonary embolism. DVTs were most often identified on the first LEDUS examination in both cohorts. Of patients diagnosed with a DVT on an LEDUS examination, a significantly higher RAP score (12 versus 10), and a shorter time to first duplex (1 versus 3 d), and DVT diagnosis (2 versus 4 d) were observed in the 2016-2017 cohort. In patients diagnosed with a pulmonary embolism, no significant differences were demonstrated between cohorts. CONCLUSIONS: Refinement of LEDUS protocols can decrease overutilization of hospital resources without compromising trauma patient outcomes.

BACKGROUND: Concern over high false-positive rates and the potential for unintended harm to patients is a critical component of the lack of widespread adoption of lung cancer screening. METHODS: An institutional database was used to identify patients who underwent lung cancer screening between 2/2015 and 2/2018 at Rush University Medical Center and Rush Oak Park Hospital. Reads were executed by dedicated thoracic radiologists and communicated using the Lung Imaging Reporting and Data System (Lung-RADS V.1). RESULTS: Six hundred and four patients were screened over the study period. We identified 21 primary lung cancers and 8 incidental cancers. We identified a false-positive rate of 17.5%. Only 9 patients underwent further investigative workup for benign disease (5.3%); however, only 4 (2.9%) of those patients were found to have inflammatory or infectious lesions, which are common mimickers of lung cancer. Excluding Lung-RADS category 3 for the purpose of quantifying risk of unintended harm from unnecessary procedures, we found a 6.9% false-positive rate, while diagnosing 25% of all Lung-RADS category 4 patients with primary lung cancer. CONCLUSION: False-positive rates in lung cancer screening programs continue to decline with improved radiologic expertise. Additionally, false-positive reporting overestimates the risk of unintended harm from further investigative procedures as only a percentage of positive findings are generally considered for tissue diagnosis (i.e., Lung-RADS category 4).

BACKGROUND: The diagnostic cascade in the emergency department (ED) has not been fully elucidated. Aim To inspect whether the usage of consulting medicine and imaging contributes to hospital outcomes. We also propose a theoretical model for better understanding the diagnostic cascade of needless medical testing. METHODS: A two-level study was conducted. The first local phase was a retrospective archive study that was conducted between 2014 and 2017 in a tertiary hospital. We extracted the number of requested imaging and consultations for each patient, and main time lags were calculated. The second-phase (January-April 2018) was conducted on a national level. We examined 22 hospitals with the emphasis on five hospital outcomes: recurrent ED visits (within 24â¯h), median waiting time at the ED, rate of early discharge at the same day and day after and percentage of patients spending >4â¯h in the ED. RESULTS: A 5% upsurge in CT scans was observed (pâ¯=â¯.032), and a significant increase was found in the number of consultations (14%, pâ¯=â¯.002). On a national level, a linear regression model found that the proportion of patients discharged from the hospital on the same day and on the day after and the proportion of patients staying in the EDâ¯>â¯4â¯h predict ED recurrence visits within 24â¯h (pâ¯=â¯.025; R2â¯=â¯46.3%). CONCLUSIONS: Upsurge in resource usage in the ED leads to a diagnostic cascade of health consumption. Further study is necessary to examine the proposed model in a global scale.

BACKGROUND: Over the past few years, a significant overuse of radiological investigations influenced the quality and cost of healthcare of the country as it may lead to non-compliance of the patient due to non-affordability and also may harm the patient in terms of radiation hazards. Pakistan, being a low-income, resource-constraint country, is facing financial impact on families as well as health system due to multiple reasons. OBJECTIVES: The purpose of study is to identify reasons of unnecessary use of radiological diagnostic modalities in Pakistani hospitals as perceived by radiologists. METHODS: A cross-sectional study was conducted on a total of all 105 radiologists, having at least 1 year experience of working in radiology, working in five tertiary care hospitals in Lahore. A self-constructed, self-administered, pretested 5-point Likert scale opinion-based questionnaire was administered after taking informed consent. It includes questions about excessive radiological use that may be attributed to the physicians, investigations, patients and other non-categorized causes. Results were analyzed using SPSS version 23. RESULTS: Since the assessment forms were handed over and collected from the radiologists in person, the response rate was 100%. Of a total of 105 respondents, 78 (74.28%) respondentsagreed that there is an actual increase, 25 (23.80%) respondents disagreed and 2 (1.90%) respondents were unsure. Most important reasons for increased usage of radiological investigations are 'need of accuracy of diagnosis' (P = 0.009), 'trend of physicians to repeat tests in order to confirm preset diagnoses' (P-value = 0.03), 'lack of knowledge about proper usage of radiological advances' (P-value = 0.005) and 'lack of proper clinical examination' (P-value = 0.04). CONCLUSION: Unnecessary use of radiological investigations is actually there as perceived by radiologists, which is attributed to inadequate knowledge, attitude and training of physicians to refer patients to radiological resources. This research can be a stepping stone for future researchers as it can be used for elaborating these causes individually and finding ways as to how each of these causes can be controlled and minimized to bring about a decline in excessive usage of these modalities for the betterment of the patients.

BACKGROUND: A large proportion of endovascular aortic aneurysm repair (EVAR) patients are routinely admitted to the intensive care unit (ICU) for postoperative observation. In this study, we aimed to describe the factors associated with ICU admission after EVAR and to compare the outcomes and costs associated with ICU vs non-ICU observation. METHODS: All patients undergoing elective infrarenal EVAR in the Premier database (2009-2015) were included. Patients were stratified as ICU vs non-ICU admission according to location on postoperative day 0. Both patient-level (sociodemographics, comorbidities) and hospital-level (teaching status, hospital size, geographic location) factors were analyzed using univariate and multivariable logistic regression to determine factors associated with ICU vs non-ICU admission. Overall outcomes and hospital costs were compared between groups. RESULTS: Overall, 8359 patients underwent elective EVAR during the study period, including 4791 (57.3%) ICU and 3568 (42.7%) non-ICU admissions. Patients admitted to ICU were more frequently nonwhite and had more comorbidities, including congestive heart failure, coronary artery disease, chronic kidney disease, chronic obstructive pulmonary disease, diabetes, and hypertension, than non-ICU patients (all, P < .03). ICU admissions were more common in small (<300 beds), urban, and nonteaching hospitals and varied greatly depending on surgeon specialty and geographic region (P < .001). A pattern emerged when admission location was clustered by hospital; ICU patients were treated at hospitals where 96.7% (interquartile range, 84.5%-98.9%) of patients were admitted to ICU after EVAR, whereas non-ICU patients were treated at hospitals where only 7.5% (interquartile range, 4.9%-25.8%) were admitted to ICU after EVAR. A multivariable logistic regression model accounting for patient-, operative-, and hospital-level differences had a significantly lower area under the curve for predicting ICU admission after EVAR than a model accounting only for hospital factors (area under the curve, 0.76 vs 0.95; P < .001). The overall rate of adverse events was higher for ICU vs non-ICU patients (16.3% vs 13.7%; P < .001). Failure to rescue (2.9% vs 3.9%; P = .42) and in-hospital mortality (0.4% vs 0.4%; P = .81) were similar between groups. After adjusting for patient and hospital factors as well as for postoperative adverse events, ICU admission after EVAR cost $1475 (95% confidence interval, $768-2183) more than non-ICU admission (P < .001). CONCLUSIONS: Among patients undergoing elective EVAR, postoperative ICU admission is more closely associated with hospital practice patterns than with individual patient risk. Routine ICU admission after EVAR adds significant cost without reducing failure to rescue or in-hospital mortality.

The aims of this study was to determine the trends in rates of caesarean sections in Turkey. The data source for this study was the Turkey Demographic and Health Survey (TDHS) 1993-1998-2003-2008-2013 conducted by Hacettepe University, Institute of Population Studies. Cross tables and binary logistic regression were used for analysis. It was found that the caesarean section rate, which was 14.3% in 1993, increased to 51.9% in 2013. The rate increased with maternal age and educational level at childbirth. The Caesarean section rate was higher in women who were under health insurance coverage, first time mothers, childbirth in the private health institutions, those staying in the Western region and urban areas, and having the highest level of wealth. This study aims to contribute to the literature of caesarean sections especially in developing countries, in which caesarean section has become a major healthcare issue. Impact Statement What is already known on this subject: Caesarean section is among the most widely practiced obstetric surgery worldwide. Previous studies have suggested that the rates of caesarean section were affected by the biological, genetic and medical factors. What the results of this study add: Besides the biological, genetic and medical factors, it is believed that social factors (income and social status, education, employment, etc.) play an important role on the caesarean section in developing countries. Although the laws on caesarean sections have been enforced since 2012 in Turkey, this study shows that there has been a significant increase in caesarean section between the 1993 and 2013 periods. The study also reveals that prohibiting caesarean sections, except in cases of medical necessity, is a problematic issue in the health system despite all efforts. What the implications are of these findings for clinical practice and/or further research: This study may be of interest for authorities and researchers in terms of showing the social factors associated with the caesarean section.

BACKGROUND: The performance of prostate health index (phi) in predicting prostate biopsy outcomes has been well established for patients with prostate-specific antigen (PSA) values between 2 and 10 ng/mL. However, the performance of phi remains unknown in patients with PSA >10 ng/mL, the vast majority in Chinese biopsy patients. We aimed to assess the ability of phi to predict prostate cancer (PCa) and high-grade disease (Gleason Score ≥7) on biopsy in a Chinese population. METHODS: This is a prospective, observational, multi-center study of consecutive patients who underwent a transrectal ultrasound guided prostate biopsy at four hospitals in Shanghai, China from August 2013 to December 2014. RESULTS: In the cohort of 1538 patients, the detection rate of PCa was 40.2%. phi had a significantly better predictive performance for PCa than total PSA (tPSA). The areas under the receiver operating characteristic curve (AUC) were 0.90 and 0.79 for phi and tPSA, respectively, P < 0.0001. A considerable proportion of patients in the cohort had PSAs >10 ng/mL (N = 838, 54.5%). The detection rates of PCa were 35.9% and 57.7% in patients with tPSA 10.1-20 and 20.1-50 ng/mL, respectively. The AUCs of phi (0.79 and 0.89, for these two groups, respectively) were also significantly higher than tPSA (0.57 and 0.63, respectively), both P < 0.0001. If a phi ≤35 was used as the cutoff, 599/1538 (39%) biopsies could have been avoided at a cost of missing small numbers of PCa patients: 49 (7.93%) PCa patients, including 18 (3.69%) high-grade tumors. CONCLUSIONS: Results from this study suggest that phi can be used to predict PCa and high-grade disease in Chinese men with high PSA levels (>10 ng/mL).

This study assessed the prescribing pattern of irrational use of antibiotic among children under age of 12 years in public and private sector hospitals in Pakistan. The prospective clinical evaluation of drug utilization pattern of antimicrobials from Patient Bedside File (PBF) of in-patients and Culture Sensitivity Test (CST) reports were evaluated to determine the antibiotic resistance. Two indicators recorded to assess antibiotic prescribing were; dose of prescribed antibiotic (low-dose, rational and high -dose) and Indication (valid or invalid). Antibiotics resistance for 25 selected antibiotics was determined by culture sensitivity test. This study showed that in Private Sector Hospital 77.7% neonates, 13.3% infants and 9% children admitted in ICU were receiving antibiotics, among them only 57.3% neonates, 62% infants and 59.9% children were found valid that is prescribed antibiotics for right indication. 27% neonates, 19% infants and 22.1% children were prescribed under dose of antibiotics, which may lead to antimicrobial resistance and increased cost of hospital stay. Only 29.1% neonates, 30% infants and 36.8% children were receiving rational dosing. In Public Sector Hospital, 65.6% neonates, 19.4% infants and 15% children were receiving antibiotics. Among them valid indication was found in 35.3% neonates, 35.6% infants and 39.8% in children. 33.3% neonates, 26.6% infants and 28.2% children were receiving under dose that may lead to resistance not only among those who were prescribed under dose but also such bacteria become resistant and spread to other population to increase antimicrobial resistance. The irrational prescribing of antibiotics was found very high (above 50%) in Public sector hospital (Hospital-B) for every age group whereas in Private sector hospital (Hospital-A) this practice was found near to 50%. In this study the prescribing frequency of Amikacin, Cefixime, Cefotaxime, Meropenem, Amoxicillin, Vancomycin, Azithromycin, Levofloxacin and Clarithromycin was found above 80% in both hospitals (A and B). Among these, Amoxicillin, Penicillin, Erythromycin and Cephalexin showed higher resistance i.e. 49.2%.

BACKGROUND: The relationship between inappropriate MPI and cardiovascular outcomes is poorly understood. We sought to systematically review the literature on appropriate use criteria (AUC) for MPI, including temporal trend of inappropriate testing and resulting cardiovascular outcomes. METHODS: We searched the MEDLINE database for studies related to AUC and MPI. The co-primary outcomes were abnormal test results and the presence of cardiac ischemia. Random effects odds ratios (OR) were constructed using DerSimonian-Laird method. RESULTS: A total of 22 studies with 23,443 patients were included. The prevalence of inappropriate testing was 14.8% [95% confidence interval (CI) 11.6%-18.7%]. Inappropriate MPI studies were less likely to be abnormal (OR 0.41 95% CI 0.35-0.49, P < .0001) and to demonstrate ischemia (OR 0.40, 95% CI 0.24-0.67, P < .0001) compared to appropriate testing. No difference in the rate of inappropriate tests was detected based on the midpoint of the enrollment year (P = .54). The pattern of ordering inappropriate studies was not different between cardiology and non-cardiology providers (OR 0.74, 95% CI 0.51-1.06, P = .10). CONCLUSION: Inappropriate MPI studies are less likely to yield abnormal results or demonstrate myocardial ischemia. The rate of inappropriate MPI has not decreased over time.

INTRODUCTION: Doctors are unfamiliar with diagnostic accuracy parameters despite routine clinical use of diagnostic tests to estimate disease probability. METHODS: Trainee doctors completed a questionnaire exploring their understanding of diagnostic accuracy parameters; ability to calculate post-test probability of a common surgical condition (appendicitis) and their perceptions on training in this area. To determine whether the method of information provision altered interpretation, trainees were randomised to receive diagnostic test information in three ways: positive test only; positive test with specificity and sensitivity; positive test with positive likelihood ratio in layman terms. RESULTS: 326 candidates were recruited across 30 training sessions. Trainees scored a median of three out of seven in questions concerning knowledge of diagnostic accuracy parameters. This was affected neither by training level (P = 0.737) nor by experience in acute general surgery (P = 0.738). 30 (11.8%) candidates correctly estimated post-test probability; with 86.6% overestimating this value. Neither level of training (P = 0.180) nor experience (P = 0.242) influenced the accuracy of the estimate. Provision of the ultrasound scan results in different ways was not associated with likelihood of a correct response (P = 0.857). CONCLUSION: This study highlights the deficiencies in trainee doctors' understanding and application of diagnostic tests results. Most trainees over-estimated disease probability, increasing the risk of unnecessary intervention and treatment.

The World Health Organization guidelines for screening and management of cervical precancerous lesions updated in 2013 made an emphasis on the use of the 'screen-and-treat' approach for cervical cancer prevention. In order to facilitate scaling-up in low income settings, most of these screen-and-treat strategies do not involve confirmatory biopsy. This yields a certain rate of overtreatment. In other words, a majority of people undergoing screen-and-treat intervention who are treated does not necessarily benefit from the treatment. Therefore, the issue of potential short term and long term complications of the recommended treatment procedures (cryotherapy and Loop Electrosurgical Excision Procedure) arises. This question has seldom been studied in resource poor countries, particularly in Sub-Saharan Africa where Human Immunodeficiency Virus infection is rampant in an epidemic fashion and where the procreative capacities are socially rewarding for women. We draw the attention of the scientific community and policy makers to the fact that the lack of evidence supporting the safety of these treatment procedures in African populations may have an impact on the acceptability of these strategies and therefore on the effectiveness of screening programs.

OBJECTIVE: Examine women's perceptions of what is 'normal' and 'desirable' in female genital appearance. DESIGN: Experiment with random allocation across three conditions. SETTING: Community. SAMPLE: A total of 97 women aged 18-30 years. METHODS: Women were randomly assigned to view a series of images of (1) surgically modified vulvas or (2) nonmodified vulvas, or (3) no images. They then viewed and rated ten target images of surgically modified vulvas and ten of unmodified vulvas. MAIN OUTCOME MEASURES: Women used a four-point Likert scale ('strongly agree' to 'strongly disagree'), to rate each target image for 'looks normal' and 'represents society's ideal'. For each woman, we created two summary scores that represented the extent to which she rated the unmodified vulvas as more 'normal' and more 'society's ideal' than the modified vulvas. RESULTS: For ratings of 'normality,' there was a significant effect for condition (F2,94 = 2.75 P = 0.007, radj2 = 0.082): women who had first viewed the modified images rated the modified target vulvas as more normal than the nonmodified vulvas, significantly different from the control group, who rated them as less normal. For ratings of 'society's ideal', there was again a significant effect for condition (F2,92 = 7.72, P < 0.001, radj2 = 0.125); all three groups rated modified target vulvas as more like society's ideal than the nonmodified target vulvas, with the effect significantly strongest for the women who had viewed the modified images. CONCLUSIONS: Exposure to images of modified vulvas may change women's perceptions of what is normal and desirable. This may explain why some healthy women seek labiaplasty.

OBJECTIVE: To individualize prostate-specific antigen threshold values to avoid overdiagnosis of prostate cancer and reduce unnecessary biopsy in elderly men. METHODS: A total of 406 men aged over 70 years old with prostate-specific antigen levels between 4.0 and 20.0 ng/ml, normal digital rectal examination results and diagnosed by transrectal needle biopsy were retrospectively analyzed. The patients were divided into a no/favorable-risk cancer group or an unfavorable-risk cancer group based on their Gleason score and the number of positive cores. Prostate-specific antigen levels, percent free prostate-specific antigen level, prostate transition zone volume and the number of previous biopsies were used to discriminate between the two groups. The optimal individualized prostate-specific antigen threshold values based on the other variables that gave a sensitivity of 95% for the detection of unfavorable-risk cancer were calculated using a boosting method for maximizing the area under the receiver operating characteristic curve. RESULTS: A total of 66 men had favorable-risk cancer, and 139 had unfavorable-risk cancer. The area under the receiver operating characteristic curve of the combination model determined by the boosting method for maximizing the area under the receiver operating characteristic curve was 0.852. The sensitivity and specificity of the threshold values for the detection of unfavorable-risk cancer were 95 and 36%, respectively. By using the threshold values, 100 (25%) of the subjects with no/favorable-risk cancer could have avoided undergoing biopsies, with a <5% risk of missing the detection of unfavorable-risk cancer. CONCLUSIONS: These individualized prostate-specific antigen threshold values may be useful for determining an indication of prostate biopsy for elderly men to avoid overdiagnosis of prostate cancer and reduce unnecessary biopsy.

Diverticulitis is a common disease in western countries and its incidence is increasing especially among young patients. Colonic diverticulosis, incidentally diagnosed by endoscopy or CT-scanning, has no immediate clinical consequences. Progression to diverticulitis develops in only 4 % of cases. In the last decades management of diverticular disease evolved and expectative treatment and less invasive techniques have gained importance. Elective resection has traditionally been advised after a second episode of diverticulitis or after a first episode if the patient was less than 50 years of age or complicated disease occurred. Recent changes in understanding the natural history of diverticular disease have substantially modified treatment paradigms. Elective resection in case of recurrent diverticular disease should be performed on a individual basis and in cases with complications like intestinal obstruction or fistulas. Primary anastomosis is an option even in emergency surgery due to colonic perforation, while diverting operations are indicated for selected patient groups with a high risk profile. Several prospective studies showed good results for laparoscopic drainage and lavage in the setting of perforated diverticulitis with generalized peritonitis, though this concept needs to be controlled with randomized clinical trials before application into the daily practice. This article should provide a short overview of trends in the surgical treatment of diverticulitis, help to understand the natural history of the disease and thereby explain the currently lower frequency of surgical interventions for diverticulitis.

After the general morbidity reduction at the beginning of the century and the routine use of prophylactic antibiotics, a hysterectomy was generously, sometimes to generously indicated in the middle of the 20th century. This might be one of the major reasons why the procedure got a bad reputation. Furthermore, in the last decade, several new treatments for benign uterine pathologies have been developed which can be proposed to the patients instead of performing a hysterectomy. Therefore, the question might be asked, if nowadays there are still some indications for a hysterectomy or if the procedure is obsolete.

Caesarean section is one of the most frequently performed operations in human medicine. It has become a routine procedure with a very low morbidity and mortality. Over the centuries, it has emerged an essential achievement in obstetric medicine. In the presence of cephalo-pelvic-disproportion, cervical dystocia, malpresentation, preterm birth, macrosomia, placental insufficiency, placenta praevia or fetal distress it is crucial to improve the perinatal morbiditiy and mortality of mother and child. The procedure has become much more frequent over the past 20 years for multiple reasons. There is variety in incidence between countries but also regional differences. It's occurrence is being influenced by level of education and socio-economic status of the pregnant woman. In the meantime, also the longterm consequences of cesarean section are well known. The potential hazards for future pregnancies and deliveries are well described. Actual controversy addresses cesarean section on demand without any medical indication, which in fact is only seldom performed in Switzerland. The ethical justification of this procedure needs to be discussed in view of the current tendency towards autonomy and self-determination of the pregnant woman.

OBJECTIVE: To determine the frequency and predictors of cardiac stress testing before elective noncardiac surgery in Medicare patients with no indications for cardiovascular evaluation. BACKGROUND: The American College of Cardiology/American Heart Association guidelines indicate that patients without class I (American Heart Association high risk) or class II cardiac conditions (clinical risk factors) should not undergo cardiac stress testing before elective noncardiac, nonvascular surgery. METHODS: We used 5% Medicare inpatient claims data (1996-2008) to identify patients aged ≥ 66 years who underwent elective general surgical, urological, or orthopedic procedures (N = 211,202). We examined the use of preoperative stress testing in the subset of patients with no diagnoses consistent with cardiac disease (N = 74,785). Bivariate and multivariate analyses were used to identify predictors of preoperative cardiac stress testing. RESULTS: Of the patients with no cardiac indications for preoperative stress testing, 3.75% (N = 2803) received stress testing in the 2 months before surgery. The rate of preoperative stress testing increased from 1.72% in 1996 to 6.44% in 2007 (P < 0.0001). A multivariate analysis adjusting for patient and hospital characteristics showed a significant increase in preoperative stress testing over time. Female sex [odds ratio (OR) 1.11; 95% CI: 1.02-1.21], presence of other comorbidities [OR 1.22; 95% confidence interval (CI): 1.09-1.35], high-risk procedure (OR 2.42; 95% CI: 2.04-2.89), and larger hospital size (OR 1.17; 95% CI: 1.03-1.32) were positive predictors of stress testing. Patients living in regions with greater Medicare expenditures (OR 1.24; 95% CI: 1.05-1.45) were also more likely to receive stress tests. CONCLUSIONS: In a 5% sample of Medicare claims data, 2803 patients underwent preoperative stress testing without any indications. When these results were applied to the entire Medicare population, we estimated that there are over 56,000 patients who underwent unnecessary preoperative stress testing. The rate of testing in patients without cardiac indications has increased significantly over time.
