Abstract
The role of the urinalysis (UA) in the management of young, febrile infants is controversial. To assess how frequently infants are treated for urinary tract infection (UTI) despite having normal UA values and to compare the characteristics of infants treated for UTI who have positive versus negative UAs, we reviewed 20,570 wellappearing febrile infants 7-60 days of age evaluated at 124 hospitals in the United States who were included in a national quality improvement project. Of 19,922 infants without bacteremia and meningitis, 2,407 (12.1%) were treated for UTI, of whom 2,298 (95.5%) had an initial UA performed. UAs were negative in 337/2,298 (14.7%) treated subjects. The proportion of infants treated for UTI with negative UAs ranged from 0%-35% across hospitals. UA-negative subjects were more likely to have respiratory symptoms and less likely to have abnormal inflammatory markers than UA+ subjects, indicating that they are mounting less of an inflammatory response to their underlying illness and/or might have contaminated specimens or asymptomatic bacteriuria.

Abstract
1. We recommend that ultrasound guidance should be used for paracentesis to reduce the risk of serious complications, the most common being bleeding. 2. We recommend that ultrasound guidance should be used to avoid attempting paracentesis in patients with an insufficient volume of intraperitoneal free fluid to drain. 3. We recommend that ultrasound guidance should be used with paracentesis to improve the success rates of the overall procedure. 4. We recommend that ultrasound should be used to assess the volume and location of intraperitoneal free fluid to guide clinical decision making of where paracentesis can be safely performed. 5. We recommend that ultrasound should be used to identify a needle insertion site based on size of the fluid collection, thickness of the abdominal wall, and proximity to abdominal organs. 6. We recommend that the needle insertion site should be evaluated using color flow Doppler ultrasound to identify and avoid abdominal wall blood vessels along the anticipated needle trajectory. 7. We recommend that a needle insertion site should be evaluated in multiple planes to ensure clearance from underlying abdominal organs and detect any abdominal wall blood vessels along the anticipated needle trajectory. 8. We recommend that a needle insertion site should be marked with ultrasound immediately before performing the procedure, and the patient should remain in the same position between marking the site and performing the procedure. 9. We recommend that using real-time ultrasound guidance for paracentesis should be considered when the fluid collection is small or difficult to access. 10. We recommend that dedicated training sessions, including didactics, supervised practice on patients, and simulation-based practice, should be used to teach novices how to perform ultrasound-guided paracentesis. 11. We recommend that simulation-based practice should be used, when available, to facilitate acquisition of the required knowledge and skills to perform ultrasoundguided paracentesis. 12. We recommend that competence in performing ultrasound-guided paracentesis should be demonstrated prior to independently performing the procedure on patients.

Abstract
Many hospitalists incorporate point-of-care ultrasound (POCUS) into their daily practice to answer specific diagnostic questions or to guide performance of invasive bedside procedures. However, standards for hospitalists in POCUS training and assessment are not yet established. Most internal medicine residency training programs, the major pipeline for incoming hospitalists, have only recently begun to incorporate POCUS in their curricula. The purpose of this document is to inform a broad audience on what POCUS is and how hospitalists are using it. This document is intended to provide guidance for the hospitalists who use POCUS and administrators who oversee its use. We discuss POCUS 1) applications, 2) training, 3) assessments, and 4) program management. Practicing hospitalists must continue to collaborate with their local credentialing bodies to outline requirements for POCUS use. Hospitalists should be integrally involved in decision-making processes surrounding POCUS program management.

Abstract
Ultrasound guidance is used increasingly to perform the following 6 bedside procedures that are core competencies of hospitalists: abdominal paracentesis, arterial catheter placement, arthrocentesis, central venous catheter placement, lumbar puncture, and thoracentesis. Yet most hospitalists have not been certified to perform these procedures, whether using ultrasound guidance or not, by specialty boards or other institutions extramural to their own hospitals. Instead, hospital privileging committees often ask hospitalist group leaders to make ad hoc intramural certification assessments as part of credentialing. Given variation in training and experience, such assessments are not straightforward "sign offs." We thus convened a panel of experts to conduct a systematic review to provide recommendations for credentialing hospitalist physicians in ultrasound guidance of these 6 bedside procedures. Pathways for initial and ongoing credentialing are proposed. A guiding principle of both is that certification assessments for basic competence are best made through direct observation of performance on actual patients.

Abstract
Executive Summary: 1) We recommend that ultrasound should be used to guide thoracentesis to reduce the risk of complications, the most common being pneumothorax. 2) We recommend that ultrasound guidance should be used to increase the success rate of thoracentesis. 3) We recommend that ultrasound-guided thoracentesis should be performed or closely supervised by experienced operators. 4) We suggest that ultrasound guidance be used to reduce the risk of complications from thoracentesis in mechanically ventilated patients. 5) We recommend that ultrasound should be used to identify the chest wall, pleura, diaphragm, lung, and subdiaphragmatic organs throughout the respiratory cycle before selecting a needle insertion site. 6) We recommend that ultrasound should be used to detect the presence or absence of an effusion and approximate the volume of pleural fluid to guide clinical decision-making. 7) We recommend that ultrasound should be used to detect complex sonographic features, such as septations, to guide clinical decision-making regarding the timing and method of pleural drainage. 8) We suggest that ultrasound be used to measure the depth from the skin surface to the parietal pleura to help select an appropriate length needle and determine the maximum needle insertion depth. 9) We suggest that ultrasound be used to evaluate normal lung sliding pre- and postprocedure to rule out pneumothorax. 10) We suggest avoiding delay or interval change in patient position from the time of marking the needle insertion site to performing the thoracentesis. 11) We recommend against performing routine postprocedure chest radiographs in patients who have undergone thoracentesis successfully with ultrasound guidance and are asymptomatic with normal lung sliding postprocedure. 12) We recommend that novices who use ultrasound guidance for thoracentesis should receive focused training in lung and pleural ultrasonography and hands-on practice in procedural technique. 13) We suggest that novices undergo simulation-based training prior to performing ultrasound-guided thoracentesis on patients. 14) Learning curves for novices to become competent in lung ultrasound and ultrasound-guided thoracentesis are not completely understood, and we recommend that training should be tailored to the skill acquisition of the learner and the resources of the institution.

Abstract
OBJECTIVES Variability exists in the treatment of neonates with urinary tract infection (UTI), potentially reflecting an overuse of resources. A cross-sectional vignette survey was designed to examine variability in physician preferences for intravenous (IV) antibiotic duration, genitourinary imaging, and prophylactic antibiotics and to evaluate drivers of resource use. METHODS The survey was administered to a random sample of pediatricians through the American Medical Association's Physician Masterfile. Respondents were provided with a case vignette of a 2-week-old neonate with a febrile UTI and asked to indicate preferences for IV antibiotic duration and rank drivers of this decision. Respondents were also asked whether they would obtain a voiding cystourethrogram (VCUG) and, regardless of preference, randomly presented with a normal result or bilateral grade II vesicoureteral reflux. The survey was delivered electronically to facilitate skip logic and randomization. RESULTS A total of 279 surveys were completed. Preference for total IV antibiotic duration differed significantly (P < .001) across specialty, with a median duration of 2 days for general pediatricians/hospitalists, 7 days for neonatologists, and 5 days for infectious disease pediatricians. For the 47% (n = 131) who did not want a VCUG, 24/61 (39%) wanted prophylactic antibiotics when presented with grade II vesicoureteral reflux (P < .001). CONCLUSIONS Subspecialty status appeared to be the most influential driver of IV antibiotic duration in the treatment of UTI. A substantial proportion of pediatricians who initially expressed a preference against ordering a VCUG wished to prescribe prophylactic antibiotics when results were abnormal, which suggests that even unwanted diagnostic test results drive treatment decisions.

Abstract
PURPOSE Central vein point-of-care ultrasonography must be reproducible to detect intravascular volume changes. We sought to determine which measurement step, image acquisition or interpretation, could be more compromising for reproducibility. METHODS Three investigators each acquired inferior vena cava (IVC) and internal jugular (IJV) vein ultrasonographic sequences (US) from a convenience sample of 21 hospitalized general medicine participants and then interpreted each US three separate times. We partitioned the random errors of acquisition and interpretation, attributing wider dispersions of each to larger reductions in reproducibility. RESULTS We analyzed 351 interpretations of 39 IVC and 432 interpretations of 48 IJV US. Reproducibility of the maximum (standard error of measurement 3.3 mm [95% confidence interval, CI 2.7-4.2 mm]) and minimum (4.8 mm [3.9-6.3 mm]) IVC diameter measurements were worse than that of the mediolateral (2.5 mm [2.0-3.2 mm]) and anteroposterior (2.5 mm [2.0-3.1 mm]) IJV diameters. The dispersions of random measurement errors were wider among acquisitions than interpretations. CONCLUSIONS Among our investigators, central vein diameter measurements obtained by point-of-care ultrasonography are not sufficiently reproducible to distinguish clinically meaningful intravascular volume changes from measurement errors. Reproducibility could be most effectively improved by reducing the random measurement errors of acquisition. © 2017 Wiley Periodicals, Inc. J Clin Ultrasound 45:488-496, 2017.

Abstract
Many hospitalists are routinely granted hospital privileges to perform invasive bedside procedures, but criteria for privileging are not well described. We conducted a survey of 21 hospitalist procedure experts from the Society of Hospital Medicine Point-of-Care Ultrasound Task Force to better understand current privileging practices for bedside procedures and how those practices are perceived. Only half of all experts reported their hospitals require a minimum number of procedures performed to grant initial (48%) and ongoing (52%) privileges for bedside procedures. Regardless, most experts thought minimums should be higher than those in current practice and should exist alongside direct observation of manual skills. Experts reported that the use of ultrasound guidance was nearly universal for paracentesis, thoracentesis, and central venous catheter placement, but only 10% of hospitals required the use of ultrasound for initial privileging of these procedures.

Abstract
BACKGROUND Evaluation of the clinical importance of outcomes in research studies is an essential element of clinical decision making. OBJECTIVE To understand how clinicians and trainees weigh the importance of different types of clinical outcomes in drug trials. METHODS A self-administered paper survey contained 4 scenarios asking participants to rate (1, "no proof" to 10, "good proof") the extent to which 4 study outcomes provided "proof that the new drug might help people." Outcomes included (1) a surrogate outcome; (2) a surrogate-enriched composite outcome; (3) stroke mortality; and (4) all-cause mortality. The primary study metrics were mean ratings for each of the 4 outcome types, and the proportion ranking outcome importance of all-cause mortality > stroke mortality > surrogate-enriched composite or surrogate alone. RESULTS A convenience sample of 549 clinicians and trainees at 2 medical centers completed the survey (response rate: 87% medical students, 80% internal medicine residents, 69% general medicine faculty, and 41% physician experts). The surrogate-enriched composite outcome and stroke mortality were rated the most important evidence for benefit (6.6 and 6.4, respectively), with all-cause mortality and a surrogate outcome being rated significantly lower (5.2 and 4.6, respectively). In addition, 48% of clinicians rated improvement in all-cause mortality as more valuable than an improvement in a surrogate marker. Only 21% rated all-cause mortality as more valuable than a surrogate-enriched composite outcome. CONCLUSIONS These findings raise concerns that clinicians and trainees may not interpret trial evidence in a way that promotes the best care for patients.

Abstract
PURPOSE Measurement of the inferior vena cava (IVC) diameters may improve decision-making for patients hospitalized with acute decompensated heart failure. Nevertheless, little is known about how the IVC is affected by loop diuretics. We sought to determine if bolus infusions of intravenous furosemide affect IVC diameters measured by hand-carried ultrasonography. METHODS We conducted a prospective cohort study at a public teaching hospital from September 2009 through June 2010. Physician investigators performed IVC ultrasonography on a convenience sample of 70 hospitalized adults who were prescribed intravenous furosemide for the diagnosis of acute decompensated heart failure. RESULTS Participants' median baseline IVC diameter was 2.38 cm (interquartile range, 1.91-2.55 cm). At 1-2 hours after furosemide, IVC diameters decreased an average of 0.21 cm (95% CI, 0.13-0.29 cm) and remained significantly below baseline at 2-3 hours after furosemide by an average of 0.15 cm (95% CI, 0.07-0.22 cm). CONCLUSIONS IVC diameters of adults diagnosed with acute decompensated heart failure become measurably smaller after single doses of intravenous furosemide. Whether this represents a true change in volume status has not been studied.

Abstract
We review the literature on diagnostic point-of-care ultrasound applications most relevant to hospital medicine and highlight gaps in the evidence base. Diagnostic point-of-care applications most relevant to hospitalists include cardiac ultrasound for left ventricular systolic function, pericardial effusion, and severe mitral regurgitation; lung ultrasound for pneumonia, pleural effusion, pneumothorax, and pulmonary edema; abdominal ultrasound for ascites, aortic aneurysm, and hydronephrosis; and venous ultrasound for central venous volume assessment and lower extremity deep venous thrombosis. Hospitalists and other frontline providers, as well as physician trainees at various levels of training, have moderate to excellent diagnostic accuracy after brief training programs for most of these applications. Despite the evidence supporting the diagnostic accuracy of point-of-care ultrasound, experimental evidence supporting its clinical use by hospitalists is limited to cardiac ultrasound.

Abstract
BACKGROUND Risk interpretation affects decision making. Yet, there is no valid assessment of how clinicians interpret the risk data that they commonly encounter. OBJECTIVE To establish the reliability and validity of a 20-item test of clinicians' risk interpretation. METHODS The Critical Risk Interpretation Test (CRIT) measures clinicians' abilities to 1) modify the interpretation based on meaningful differences in the outcome (e.g., disease specific v. all-cause mortality) and time period (e.g., lifetime v. 10-year mortality), 2) maintain a stable interpretation for different risk framings (e.g., relative v. absolute risk), and 3) correctly interpret how diagnostic testing modifies risk. There were 658 clinicians and medical trainees who participated: 116 nurse practitioners (NPs) at a national conference, 273 medical students at 1 institution, 148 residents in internal medicine at 2 institutions, and 121 internists at 1 institution. Participants completed a self-administered paper test during educational conferences. Seventeen evidence-based medicine experts took the test online and formally assessed content validity. Eighteen second-year medical students were recruited to take the test and a retest 3 weeks later to explore test-retest correlation. RESULTS Expert review supported test clarity and content validity. Factor analysis supported that the CRIT identifies at least 3 separable areas of clinician knowledge. Test-retest correlation was fair (intraclass correlation coefficient = 0.65; standard error = 0.15). Scores on our test correlated with other tests of related abilities. Mean test scores varied among groups, with differences in prior evidence-based medicine training and experience (93 for NPs, 101 for medical students, 101 for residents, 103 for academic internists, and 110 for physician experts; P < 0.001). CONCLUSIONS Our results provide supporting evidence for the reliability and validity of the CRIT as an index of critical risk interpretation abilities, which is acceptable and feasible to administer in an educational setting.

Abstract
CONTEXT Data are sparse on the effect of varying the durations of internal medicine attending physician ward rotations. OBJECTIVE To compare the effects of 2- vs 4-week inpatient attending physician rotations on unplanned patient revisits, attending evaluations by trainees, and attending propensity for burnout. DESIGN, SETTING, AND PARTICIPANTS Cluster randomized crossover noninferiority trial, with attending physicians as the unit of crossover randomization and 4-week rotations as the active control, conducted in a US university-affiliated teaching hospital in academic year 2009. Participants were 62 attending physicians who staffed at least 6 weeks of inpatient service, the 8892 unique patients whom they discharged, and the 147 house staff and 229 medical students who evaluated their performance. INTERVENTION Assignment to random sequences of 2- and 4-week rotations. MAIN OUTCOME MEASURES Primary outcome was 30-day unplanned revisits (visits to the hospital's emergency department or urgent ambulatory clinic, unplanned readmissions, and direct transfers from neighboring hospitals) for patients discharged from 2- vs 4-week within-attending-physician rotations. Noninferiority margin was a 2% increase (odds ratio [OR] of 1.13) in 30-day unplanned patient revisits. Secondary outcomes were length of stay; trainee evaluations of attending physicians; and attending physician reports of burnout, stress, and workplace control. RESULTS Among the 8892 patients, there were 2437 unplanned revisits. The percentage of 30-day unplanned revisits for patients of attending physicians on 2-week rotations was 21.2% compared with 21.5% for 4-week rotations (mean difference, -0.3%; 95% CI, -1.8% to +1.2%). The adjusted OR of a patient having a 30-day unplanned revisit after 2- vs 4-week rotations was 0.97 (1-sided 97.5% upper confidence limit, 1.07; noninferiority P = .007). Average length of stay was not significantly different (geometric means for 2- vs 4-week rotations were 67.2 vs 67.5 hours; difference, -0.9%; 95% CI, -4.7% to +2.9%). Attending physicians were more likely to score lower in their ability to evaluate trainees after 2- vs 4-week rotations by both house staff (41% vs 28% rated less than perfect; adjusted OR, 2.10; 95% CI, 1.50-3.02) and medical students (82% vs 69% rated less than perfect; adjusted OR, 1.41; 95% CI, 1.06-2.10). They were less likely to report higher scores of both burnout severity (16% vs 35%; adjusted OR, 0.39; 95% CI, 0.26-0.58) and emotional exhaustion (19% vs 37%; adjusted OR, 0.45; 95% CI, 0.31 to 0.64) after 2- vs 4-week rotations. CONCLUSIONS The use of 2-week inpatient attending physician rotations compared with 4-week rotations did not result in an increase in unplanned patient revisits. It was associated with better self-rated measures of attending physician burnout and emotional exhaustion but worse evaluations by trainees.

Abstract
BACKGROUND Hospitalists can use hand-carried echocardiography for accurate point-of-care information, but patient outcome data for its application are sparse. METHODS We performed an unblinded, parallel-group randomized trial between July 2008 and March 2009 at one teaching hospital in Chicago, Illinois. We randomly assigned adult general medicine inpatients referred for standard echocardiography with indications investigatable by hand-carried echocardiography to care guided by hand-carried echocardiography or usual care. The main outcome measure was length of stay on the referring hospitalist's service. Secondary outcomes included a before-after analysis of reported changes in management due to hand-carried echocardiography and the diagnostic accuracy of hand-carried echocardiography. RESULTS The difference in length of stay between 226 participants randomized to care guided by hand-carried echocardiography (geometric mean 46.1 hours, interquartile range 29.0-70.9 hours) and 227 participants randomized to usual care (46.9 hours, interquartile range 34.1-68.3 hours) corresponded to a 1.7% reduction in length of stay that was not statistically significant (95% confidence interval, -12.1 to 9.8%). In post hoc subgroup analyses, care guided by hand-carried echocardiography reduced length of stay in participants who were referred for heart failure (P=.0008). Among participants who underwent both hand-carried and standard echocardiography, hospitalists changed management due to hand-carried echocardiography in 37%. Despite the favorable diagnostic accuracy of hand-carried echocardiography, most changes to the timing of hospital discharge occurred after standard echocardiography. CONCLUSION Hospitalist care guided by hand-carried echocardiography for unselected general medicine patients does not meaningfully affect length of stay. Whether or not it affects care quality remains unstudied.

Abstract
Atherosclerosis is a risk factor for dementia. However, little is known about the association between cognitive performance and a widely used indicator of coronary heart disease, at rest electrocardiography. We identified 839 older residents (mean age 81 years, 58% black) from a geographically defined biracial community in Chicago, Illinois, who had undergone extensive cognitive performance testing and met the electrocardiographic eligibility criteria, including a QRS duration of < 120 ms. We then examined multivariate regression coefficients that described the associations between global cognitive performance and 4 novel descriptors of ventricular repolarization waveforms. All analyses were adjusted for age, gender, education, and race. The T wave nondipolar voltage had a significant association with global cognitive performance (p = 0.01), and this association largely remained after adjustment for cardiovascular disease risk factors (p = 0.03). In contrast, global cognitive performance was not significantly associated with the rate-adjusted QT interval, the voltage change from the beginning to end of the ST segment in lead V(5), or the spatial angle between the mean QRS and T wave vectors. In conclusion, the strengths of the associations varied between the novel electrocardiographic descriptors of ventricular repolarization and global cognitive performance. Nevertheless, the significant association observed with T wave nondipolar voltage suggests that the cardiac effects of heart disease are associated with cognitive declines.

Abstract
BACKGROUND The duration of training needed for hospitalists to accurately perform hand-carried ultrasound echocardiography (HCUE) is uncertain. OBJECTIVE To determine the diagnostic accuracy of HCUE performed by hospitalists after a 27-hour training program. DESIGN Prospective cohort study. SETTING Large public teaching hospital. PATIENTS A total of 322 inpatients referred for standard echocardiography (SE) between March and May 2007. INTERVENTION Blinded to SE results, attending hospitalist physicians performed HCUE within hours of SE. MEASUREMENTS Diagnostic characteristics of HCUE as a test for 6 cardiac abnormalities assessed by SE: left ventricular (LV) systolic dysfunction; severe mitral regurgitation (MR); moderate or severe left atrium (LA) enlargement; moderate or severe LV hypertrophy; medium or large pericardial effusion; and dilatation of the inferior vena cava (IVC). RESULTS A total of 314 patients underwent both SE and HCUE within a median time of 2.8 hours (25th to 75th percentiles, 1.4 to 5.1 hours). Positive and negative likelihood ratios for HCUE increased and decreased, respectively, the prior odds by 5-fold or more for LV systolic dysfunction, severe MR regurgitation, and moderate or large pericardial effusion. Likelihood ratios changed the prior odds by 2-fold or more for moderate or severe LA enlargement, moderate or severe LV hypertrophy, and IVC dilatation. Indeterminate HCUE results occurred in 2% to 6% of assessments. CONCLUSIONS The diagnostic accuracy of HCUE performed by hospitalists after a brief training program was moderate to excellent for 6 important cardiac abnormalities.

Abstract
BACKGROUND Short-stay units (SSUs) provide an alternative to traditional inpatient services for patients with short anticipated hospital stays. Yet little is known about which patient types predict SSU success. OBJECTIVE To describe patients admitted to our hospitalist-run SSU and explore predictors of length-of-stay (LOS) and eventual admission to traditional inpatient services. DESIGN Prospective observational cohort study. SETTING Large public teaching hospital. PATIENTS Consecutive admissions (n = 755) to the SSU over 4 months. INTERVENTION Hospitalist attending physicians prospectively collected data from patients' histories, physical exams, and medical records upon admission and discharge. MEASUREMENTS Risk assessments were made for patients with our most common provisional diagnoses: possible acute coronary syndrome (ACS) and heart failure. Patient stays were considered successful when LOS was less than 72 hours and eventual admission to traditional inpatient services was not required. RESULTS Of 738 eligible patients, 79% (n = 582) had successful SSU stays. In a multivariable model, the provisional diagnosis of heart failure predicted stays longer than 72 hours (P = 0.007) but risk assessments were unimportant. Patients who received specialty consultations were most likely to need eventual admission (odds ratio [OR], 13.1; 95% confidence interval [CI], 6.9-24.9), and the likelihood of long stays was inversely proportional to the accessibility of diagnostic tests. CONCLUSIONS In our hospitalist-run SSU, the inaccessibility of diagnostic tests and the need for specialty consultations were the most important predictors of unsuccessful stays. Designs for other SSUs that care for mostly low-risk patients should focus on matching patients' diagnostic and consultative needs with readily accessible services.

Abstract
BACKGROUND Procedure services may improve the training of bedside procedures. However, little is known about how procedure services may affect the demand for and success of procedures performed on general medicine inpatients. OBJECTIVE Determine whether a procedure service affects the number and success of 4 bedside procedures (paracentesis, thoracentesis, lumbar puncture, and central venous catheterization) attempted on general medicine inpatients. DESIGN Prospective cohort study. SETTING Large public teaching hospital. PATIENTS Nineteen hundred and forty-one consecutive admissions to the general medicine service. INTERVENTION A bedside procedure service was offered to physicians from 1 of 3 firms for 4 weeks. This service then crossed over to physicians from the other 2 firms for another 4 weeks. MEASUREMENTS Data on all procedure attempts were collected daily from physicians. We examined whether the number of attempts and the proportion of successful attempts differed based on whether firms were offered the beside procedure service. RESULTS The number of procedure attempts was 48% higher in firms offered the service (90 versus 61 per 1000 admissions; RR 1.48, 95% CI 1.06-2.10; P = .030). More than 85% of the observed increase was a result of procedures with therapeutic indications. There were no differences between firms in the proportions of successful attempts or major complications. CONCLUSIONS The availability of a procedure service may increase the overall demand for bedside procedures. Further studies should refine the indications for and anticipated benefits from these commonly performed invasive procedures.

Abstract
OBJECTIVE Previous studies have shown that most medical inpatients receive treatment supported by strong evidence (evidence-based treatment), but they have not assessed whether and how physicians actually use evidence when making their treatment decisions. We investigated whether physicians would change inpatient treatment if presented with the results of a literature search. DESIGN Before-after study. SETTING Large public teaching hospital. PARTICIPANTS Random sample of 146 inpatients cared for by 33 internal medicine attending physicians. INTERVENTIONS After physicians committed to a specific diagnosis and treatment plan, investigators performed standardized literature searches and provided the search results to the attending physicians. MEASUREMENTS AND MAIN RESULTS The primary study outcome was the number of patients whose attending physicians would change treatment due to the literature searches. These changes were evaluated by blinded peer review. A secondary outcome was the proportion of patients who received evidence-based treatment before and after the literature searches. Attending physicians changed treatment for 23 (18%) of 130 eligible patients (95% confidence interval, 12% to 24%) as a result of the literature searches. Overall, 86% of patients (112 of 130) received evidence-based treatments before the searches and 87% (113 of 130) after the searches. Changes were not related to whether patients were receiving evidence-based treatment before the search (P =.6). Panels of peer reviewers judged the quality of patient care as improved or maintained for 18 (78%) of the 23 patients with treatment changes. CONCLUSIONS Searching the literature could improve the treatment of many medical inpatients, including those already receiving evidence-based treatment.
