Blunt cardiac injury in the hemodynamically stable patient.

ABSTRACT: Blunt cardiac injury (BCI) describes a spectrum of problems including severe, potentially life-threatening injuries from trauma. Pericardial effusion is an example of a BCI that has generally been assumed to imply serious underlying injury to the heart and should be considered hemopericardium until proven otherwise. A standard of care has been established to screen for BCI and treat hemodynamically unstable patients with an acute pericardial effusion presumably related to BCI. Less agreement exists on definitive treatment for hemodynamically stable patients with pericardial effusion after blunt cardiac trauma. This case study explores a new treatment for small to moderate hemopericardium in a stable patient after BCI.

Emotion regulation relates to clinical characteristics and quality of life but not daily functioning in psychosis spectrum outpatients.

Difficulties in emotion regulation (ER) can negatively impact the clinical course and outcomes of a range of psychiatric conditions, including psychosis spectrum disorders. Individuals with psychosis may exhibit poorer ER abilities, which have been associated with increased severity and distress of psychotic symptoms. A paucity of research has investigated the clinical correlates of ER in psychosis and the influence of these difficulties on indices of recovery, such as daily functioning and quality of life. In the present study, 59 outpatients presenting for Cognitive Behaviour Therapy for psychosis (CBTp) in a large psychiatric hospital completed an intake assessment of clinician-rated and self-reported measures prior to treatment. Poor ER abilities were positively correlated with positive symptoms (overall and delusions), social anxiety, depression, and self-reflectiveness and negatively correlated with quality of life and personal recovery. Multiple regression analyses showed ER was a significant predictor of quality of life but not daily functioning, which was predicted most by cognition and psychiatric symptoms. Overall, findings support the clinical utility of assessing emotion dysregulation in psychosis and provide a more nuanced understanding of how such challenges differentially influence recovery in psychosis, which can further inform treatment planning and intervention.

Validation of the American Association for the Surgery of Trauma Emergency General Surgery Grading System for Colorectal Resection: An EAST Multicenter Study.

BACKGROUND: The American Association for the Surgery of Trauma (AAST) has developed a grading system for emergency general surgery (EGS) conditions. We sought to validate the AAST EGS grades for patients undergoing urgent/emergent colorectal resection. METHODS: Patients enrolled in the "Eastern Association for the Surgery of Trauma Multicenter Colorectal Resection in EGS-to anastomose or not to anastomose" study undergoing urgent/emergent surgery for obstruction, ischemia, or diverticulitis were included. Baseline demographics, comorbidity severity as defined by Charlson comorbidity index (CCI), procedure type, and AAST grade were prospectively collected. Outcomes included length of stay (LOS) in-hospital mortality, and surgical complications (superficial/deep/organ-space surgical site infection, anastomotic leak, stoma complication, fascial dehiscence, and need for further intervention). Multivariable logistic regression models were used to describe outcomes and risk factors for surgical complication or mortality. RESULTS: There were 367 patients, with a mean (± SD) age of 62 ± 15 years. 39% were women. The median interquartile range (IQR) CCI was 4 (2-6). Overall, the pathologies encompassed the following AAST EGS grades: I (17, 5%), II (54, 15%), III (115, 31%), IV (95, 26%), and V (86, 23%). Management included laparoscopic (24, 7%), open (319, 87%), and laparoscopy converted to laparotomy (24, 6%). Higher AAST grade was associated with laparotomy (P = .01). The median LOS was 13 days (8-22). At least 1 surgical complication occurred in 33% of patients and the mortality rate was 14%. Development of at least 1 surgical complication, need for unplanned intervention, mortality, and increased LOS were associated with increasing AAST severity grade. On multivariable analysis, factors predictive of in-hospital mortality included AAST organ grade, CCI, and preoperative vasopressor use (odds ratio (OR) 1.9, 1.6, 3.1, respectively). The American Association for the Surgery of Trauma emergency general surgery grade was also associated with the development of at least 1 surgical complication (OR 2.5), while CCI, preoperative vasopressor use, respiratory failure, and pneumoperitoneum were not. CONCLUSION: The American Association for the Surgery of Trauma emergency general surgery grading systems display construct validity for mortality and surgical complications after urgent/emergent colorectal resection. These results support incorporation of AAST EGS grades for quality benchmarking and surgical outcomes research.

Increasing Access to CBT for Psychosis: Development, Feasibility, and Acceptability of a Specialized Outpatient Service.

Despite the increasing demand for cognitive behavioural therapy for psychosis (CBTp), the existing literature is lacking in terms of models for sustainable implementation. The aims of this study were to: (a) describe the development of a specialized CBTp Service; (b) report demographic characteristics and referral patterns over 1 year to examine feasibility; and (c) review feedback from participants in group-based CBTp to examine acceptability. Data were analyzed from 126 referrals (M = 35.52, SD = 13.06, 59.5% men) to an outpatient CBTp Service at the Centre for Addiction and Mental Health (Toronto, Ontario) between January 2019 to January 2020. Anonymous feedback was obtained from 54 individuals who completed group-based CBTp. Positive symptoms and distressing emotions were the main reasons for referral. Over half of eligible referrals scheduled an intake assessment and 70% of individuals who completed this assessment attended further treatment. Primary reasons for service refusal were scheduling conflicts and illness-related barriers. The total service wait-time was two months, with the longest delay between dates of referral and initial contact. Satisfaction with the quality of CBTp and its components was rated high among group members. Although variable wait-times and engagement levels were identified across stages of the referral process, the CBTp Service demonstrates preliminary feasibility and acceptability, and provides a model of service delivery to incorporate within future CBTp implementation efforts in Canada.

Money talks: The influence of extrinsic motivators on social cognition in early episode psychosis.

Amotivation is a central feature of psychosis that can lead to underperformance on a variety of tasks, including neurocognitive testing; however, there is some evidence that neurocognitive impairments resulting from low effort can be ameliorated with the use of monetary reinforcement. While cross-sectional data has also shown that amotivation is associated with social cognitive performance, limited research has examined the directionality of this relationship, and whether monetary reinforcement can similarly reduce these impairments. In the present study, 35 patients with early psychosis and 35 community controls were randomized to either a reward condition in which they received monetary reinforcement for every correct response on a theory of mind (ToM) task, or a non-reward condition in which no feedback was provided. A significant group by condition interaction emerged after adjusting for premorbid intelligence and global neurocognition, F(1, 63) = 7.76, p = .007. Post-hoc analyses revealed that performance on the ToM task was similar across conditions for controls, whereas early psychosis patients in the reward condition had clinically and statistically significant differences in ToM performance compared to patients in the non-reward condition. These results suggest that social cognitive task performance may underrepresent actual ability in the early stages of psychosis. Future research is needed to discriminate the relative effects of monetary reinforcement, corrective feedback, and/or a combination of these factors to better understand performance differences between conditions, which appeared to be unique to early psychosis patients.

The Effect of Changes in Alcohol Tax Differentials on Alcohol Consumption.

We show that tax-induced increases in alcohol prices can lead to substantial substitution and avoidance behavior that limits reductions in alcohol consumption. Causal estimates are derived from a natural experiment in Illinois where spirits and wine taxes were raised sharply and unexpectedly in 2009. Beer taxes were increased by only a trivial amount. We construct representative and consistent measures of alcohol prices and sales from scanner data collected for hundreds of products in thousands of stores across the US. Using several difference-in-differences models, we show that alcohol excise taxes are instantly over-shifted. That is, a $1 tax increase translates into a price increase of up to $1.50. We find evidence suggesting that consumers react by switching to less expensive products. In particular, they increase purchases of beer, thus significantly moderating any tax-induced reductions in total ethanol consumption. Our study highlights the importance of tax-induced substitution, the implications of differential tax increases by beverage group and the impacts on public health of alternative types of tax hikes whose main aims are to increase revenue.

Association of e-cigarette advertising with e-cigarette and cigarette use among US adults.

AIMS: To estimate the association of e-cigarette advertisement exposure with e-cigarette and cigarette use behavior among US adults. DESIGN: Data from the 2013-14 National Adult Tobacco Survey (NATS) were linked to Kantar Media and National Consumer Study data to construct measures of e-cigarette advertisements on TV and in magazines. The relationship between advertisement measures and outcomes was estimated using logistic and Poisson regressions, controlling for socio-demographics, state cigarette taxes and state and year fixed-effects. SETTING: United States. PARTICIPANTS/CASES: A total of 98 746 adults aged ≥ 18 years who responded to the 2013-14 NATS. MEASUREMENTS: The independent variables of interest were the number of e-cigarette advertisements in magazines to which an adult was exposed in the past 6 months and the number of e-cigarette advertisements on TV to which an adult was exposed in the past 6 months. Outcomes were awareness of e-cigarettes, ever e-cigarette use, current e-cigarette use, current cigarette use and number of cigarettes smoked per month. FINDINGS: Exposure to one additional e-cigarette advertisement on TV was associated with a 0.18, 0.13 and 0.03 percentage point increase, respectively, in awareness, ever use and current use of e-cigarettes among all adults (P < 0.05). This exposure also was associated with a 0.11 percentage point increase in current cigarette use among all adults and an increase in cigarette consumption of 2.24 cigarettes per month among adults aged ≥ 45 (P < 0.05). CONCLUSIONS: Exposure to e-cigarette advertising appears to be positively associated with the use of e-cigarettes and cigarettes among adults of all ages, and with increased cigarette consumption among older adults.

Colorectal resection in emergency general surgery: An EAST multicenter trial.

OBJECTIVE: Evidence comparing stoma creation (STM) versus anastomosis after urgent or emergent colorectal resection is limited. This study examined outcomes after colorectal resection in emergency general surgery patients. METHODS: This was an Eastern Association for the Surgery of Trauma-sponsored prospective observational multicenter study of patients undergoing urgent/emergent colorectal resection. Twenty-one centers enrolled patients for 11 months. Preoperative, intraoperative, and postoperative variables were recorded. χ, Mann-Whitney U test, and multivariable logistic regression models were used to describe outcomes and risk factors for surgical complication/mortality. RESULTS: A total of 439 patients were enrolled (ANST, 184; STM, 255). The median (interquartile range) age was 62 (53-71) years, and the median Charlson Comorbidity Index (CCI) was 4 (1-6). The most common indication for surgery was diverticulitis (28%). Stoma group was older (64 vs. 58 years, p < 0.001), had a higher CCI, and were more likely to be immunosuppressed. Preoperatively, STM patients were more likely to be intubated (57 vs. 15, p < 0.001), on vasopressors (61 vs. 13, p < 0.001), have pneumoperitoneum (131 vs. 41, p < 0.001) or fecal contamination (114 vs. 33, p < 0.001), and had a higher incidence of elevated lactate (149 vs. 67, p < 0.001). Overall mortality was 13%, which was higher in STM patients (18% vs. 8%, p = 0.02). Surgical complications were more common in STM patients (35% vs. 25%, p = 0.02). On multivariable analysis, management with an open abdomen, intraoperative blood transfusion, and larger hospital size were associated with development of a surgical complication, while CCI, preoperative vasopressor use, steroid use, open abdomen, and intraoperative blood transfusion were independently associated with mortality. CONCLUSION: This study highlights a tendency to perform fecal diversion in patients who are acutely ill at presentation. There is a higher morbidity and mortality rate in STM patients. Independent predictors of mortality include CCI, preoperative vasopressor use, steroid use, open abdomen, and intraoperative blood transfusion. Following adjustment by clinical factors, method of colon management was not associated with surgical complications or mortality. LEVEL OF EVIDENCE: Therapeutic study, level IV.

E-Cigarettes and Adult Smoking: Evidence from Minnesota.

E-cigarettes provide nicotine in a vapor form, which is considered less harmful than the smoke from combustible cigarettes because it does not contain the toxins that are found in tobacco smoke. E-cigarettes may be effective in helping smokers to quit or they might simply provide smokers a method of bypassing smoking restrictions. There is very little causal evidence to date on how e-cigarette use impacts smoking cessation among adults. Minnesota was the first to impose a tax on e-cigarettes. This tax provides a plausibly exogenous deterrent to e-cigarette use. We utilize data from the Current Population Survey Tobacco Use Supplements from 1992 to 2015 to assess how the Minnesota tax increase impacted smoking cessation among adult smokers. Estimates suggest that the e-cigarette tax increased adult smoking and reduced smoking cessation in Minnesota, relative to the control group, and imply a cross elasticity of current smoking participation with respect to e-cigarette prices of 0.13. Our results suggest that in the sample period about 32,400 additional adult smokers would have quit smoking in Minnesota in the absence of the tax. If this tax were imposed on a national level about 1.8 million smokers would be deterred from quitting in a ten year period. The taxation of e-cigarettes at the same rate as cigarettes could deter more than 2.75 million smokers nationally from quitting in the same period. The public health benefits of not taxing e-cigarettes, however, must be weighed against effects of this decision on efforts to reduce vaping by youth.

Non-Trauma Service Admissions: Should We Care?

The American College of Surgeons Committee on Trauma requires that trauma centers with greater than 10 per cent injured patients admitted to non-trauma services (NTSs) have processes to review these for appropriateness of care. We previously described an algorithm to determine the appropriateness of NTS admissions. Our objective was to determine if the outcome and process of care was similar between TS- and NTS-admitted patients. We conducted a retrospective analysis of our trauma registry. NTS-appropriate patients by algorithm were included. Differences between patients admitted to a TS and an NTS were compared. Nine hundred forty-one patients met the algorithm criteria as appropriate for the NTS; 694 were admitted to TS and 247 to NTS. Contact with TS was the most common association with admission to TS. NTS patients were older and had similar Injury Severity Scores, and a similar proportion had three or greater pre-existing comorbidities. NTS-admitted patients had similar risk for mortality and complications, but longer length of stay, and were less likely to have a desirable discharge disposition. Minimally injured elderly patients constitute most of NTS and a large proportion of TS admissions. NTS admission seems appropriate with respect to mortality and complications. Differences in the care process may have accounted for longer length of stay and differences in disposition destination.

Jumping to social conclusions?: The implications of early and uninformed social judgements in first episode psychosis.

Although social cognition is now understood to be a key determinant of functional outcome in psychosis, the factors associated with impaired performance on tasks of social cognition still remain unclear. Jumping to conclusions (JTC) is a cognitive bias that is commonly observed in psychosis, and features of this bias may be implicated in the accurate processing of social information. In the present study, a sample of patients in the early stages of psychosis (n = 35) and demographically matched community controls (n = 35) were presented with a modified version of the Interpersonal Perception Task in which video clips of naturalistic social scenarios were paused at 3 predetermined time points. All participants were prompted to answer a series of questions during these time points to examine the processes by which individuals arrive at social judgments. A JTC response pattern was defined as endorsing overconfident responses and a low need for additional social information at the beginning time points of the video clips when limited social cues were available. Compared with controls, a greater proportion of patients exhibited a response pattern suggestive of JTC, which was also strongly associated with poorer overall task accuracy, regardless of group status. Results from this study provide evidence that overconfidence in premature and uninformed social judgments has direct consequences for the accurate processing of social information. Furthermore, this response pattern, which was more characteristic of early psychosis patients, may represent JTC in real-world social contexts, and could be an important therapeutic target for social cognition in the early stages of illness.

Patterns and perceptions of face-to-face and digital communication in the clinical high risk and early stages of psychosis.

Digital communication can mitigate some of the challenges inherent in face-to-face communication; however, it is unclear whether this communication format is preferred among youth with emerging psychosis. Therefore, we examined characteristics of face-to-face and digital communication in youth at clinical high risk for psychosis (CHR; n = 19) or in the first episode of psychosis (FEP; n = 57), as well as age-matched community comparisons (n = 51). Participants completed a 25-item self-report questionnaire to assess between- and within-group differences in the frequency of, satisfaction with, and barriers to face-to-face and digital communication. Compared to controls, both clinical groups endorsed a lower frequency of face-to-face and digital interactions across a range of communication partners. Controls reported higher satisfaction and fewer challenges with both communication formats than CHR and FEP groups. No between-group differences were identified among clinical participants in characteristics of face-to-face and digital interactions. Youth at clinical high risk for, or in the first episode of, psychosis exhibited similar communication patterns and perceptions that significantly diverged from community controls. These findings highlight that reductions in the quality and quantity of social interactions extend to digital contexts, and that both communication formats are relevant clinical targets in the high risk and early stages of psychosis.

Does e-cigarette advertising encourage adult smokers to quit?

We provide the first causal evidence on whether e-cigarette advertising on television and in magazines encourages adult smokers to quit. We find the answer to be yes for TV advertising but no for magazine advertising. Our results indicate that a policy banning TV advertising of e-cigs would have reduced the number of smokers who quit in the recent past by approximately 3%. If the FDA were not considering regulations and mandates, e-cig ads might have reached the number of nicotine replacement therapy TV ads during that period. That would have increased the number of smokers who quit by around 10%.

Atrioventricular conduction in patients undergoing pacemaker implant following self-expandable transcatheter aortic valve replacement.

BACKGROUND: Heart block requiring a pacemaker is common after self-expandable transcatheter aortic valve replacement (SE-TAVR); however, conduction abnormalities may improve over time. Optimal device management in these patients is unknown. OBJECTIVE: To evaluate the long-term, natural history of conduction disturbances in patients undergoing pacemaker implantation following SE-TAVR. METHODS: All patients who underwent new cardiac implantable electronic device (CIED) implantation at Michigan Medicine following SE-TAVR placement between January 1, 2012 and September 25, 2017 were identified. Electrocardiogram and device interrogation data were examined during follow-up to identify patients with recovery of conduction. Logistic regression analysis was used to compare clinical and procedural variables to predict conduction recovery. RESULTS: Following SE-TAVR, 17.5% of patients underwent device placement for new atrioventricular (AV) block. Among 40 patients with an average follow-up time of 17.1 ± 8.1 months, 20 (50%) patients had durable recovery of AV conduction. Among 20 patients without long-term recovery, four (20%) had transient recovery. The time to transient conduction recovery was 2.2 ± 0.2 months with repeat loss of conduction at 8.2 ± 0.9 months. On multivariate analysis, larger aortic annular size (odds ratio: 0.53 [0.28-0.86]/mm, P = 0.02) predicted lack of conduction recovery. CONCLUSIONS: Half of the patients undergoing CIED placement for heart block following SE-TAVR recovered AV conduction within several months and maintained this over an extended follow-up period. Some patients demonstrated transient recovery of conduction before recurrence of conduction loss. Larger aortic annulus diameter was negatively associated with conduction recovery.

Comparison of the neurocognitive profiles of individuals with elevated psychotic or depressive symptoms.

AIM: Neurocognitive deficits are pervasive and enduring features of severe mental illness that appear before the onset of clinical symptoms and contribute to functional disability. However, it remains unclear how individuals who display warning signs for psychotic or mood disorders compare on their neurocognitive profiles since previous studies have separately examined neurocognition in both groups. Therefore, the purpose of this study was to directly compare performance on a range of neurocognitive tasks in individuals with emerging psychotic or mood symptoms. METHODS: Participants were drawn from a database of individuals who completed a comprehensive assessment at a university-based assessment centre. We examined 3 groups: individuals who endorsed elevated psychotic symptoms (EPS; n = 64), individuals who endorsed elevated depressive symptoms (EDS; n = 58), or non-clinical comparisons (NCC; n = 57) without any elevated psychiatric symptoms or diagnoses. RESULTS: EPS participants performed worse than NCC and EDS groups on verbal comprehension, working memory and cognitive flexibility, and worse than NCC, but not EDS, on perceptual reasoning. There were no significant differences between groups on processing speed, verbal fluency and set-shifting. EDS performed worse than both EPS and NCC groups on psychomotor speed. Dimensionally, poorer cognitive functioning was more strongly related to EPS than depressive symptoms. CONCLUSIONS: These findings highlight the distinct yet overlapping neurocognitive profiles of both groups with emerging psychiatric symptoms, and suggest that, despite having no formal diagnosis, individuals with EPS exhibit observable cognitive impairment and may still benefit from interventions within academic and workplace contexts.

Nonsurgical Admissions With Traumatic Injury: Medical Patients Are Trauma Patients Too.

Nontrauma service (NTS) admissions are an increasing problem as ground-level falls in elderly patients become more common. The admission and evaluation of trauma patients to nontrauma services in trauma centers seeking American College of Surgeons (ACS) verification, must follow the ACS mandates for performance improvement requiring some method of evaluating this population when admitted to services other than trauma, orthopedics, and neurosurgery. The purpose of this study and performance improvement project was to improve our process for the definition and evaluation of trauma patients who were being admitted to nontrauma services. We designed an algorithm to evaluate appropriateness of NTS admission and evaluated outcomes for NTS admissions utilizing that algorithm.We created a scoring algorithm and evaluated appropriateness of NTS admission over 2 years in a community-teaching ACS Level II trauma center. We reviewed trauma registry data using χ and Fisher exact tests to determine differences in outcome for NTS versus trauma service (TS) admissions.From December 2014 to December 2016, NTS admission rate fell from maximum of 28% to 4% stabilizing between 8% and 10%. Mortality and overall complication rate between NTS and TS were similar (p = .40 and .66, respectively), but length of stay was lower for TS admissions (p < .0001).A scoring system of algorithm can be used to determine appropriateness of NTS admissions, and validity of the tool can be confirmed using registry-based outcome data for TS versus NTS admissions.

Occupational exposure during emergency department thoracotomy: A prospective, multi-institution study.

BACKGROUND: Occupational exposure is an important consideration during emergency department thoracotomy (EDT). While human immunodeficiency virus/hepatitis prevalence in trauma patients (0-16.8%) and occupational exposure rates during operative trauma procedures (1.9-18.0%) have been reported, exposure risk during EDT is unknown. We hypothesized that occupational exposure risk during EDT would be greater than other operative trauma procedures. METHODS: A prospective, observational study at 16 US trauma centers was performed (2015-2016). All bedside EDT resuscitation providers were surveyed with a standardized data collection tool and risk factors analyzed with respect to the primary end point, EDT occupational exposure (percutaneous injury, mucous membrane, open wound, or eye splash). Provider and patient variables and outcomes were evaluated with single and multivariable logistic regression analyses. RESULTS: One thousand three hundred sixty participants (23% attending, 59% trainee, 11% nurse, 7% other) were surveyed after 305 EDTs (gunshot wound, 68%; prehospital cardiopulmonary resuscitation, 57%; emergency department signs of life, 37%), of which 15 patients survived (13 neurologically intact) their hospitalization. Overall, 22 occupational exposures were documented, resulting in an exposure rate of 7.2% (95% confidence interval [CI], 4.7-10.5%) per EDT and 1.6% (95% CI, 1.0-2.4%) per participant. No differences in trauma center level, number of participants, or hours worked were identified. Providers with exposures were primarily trainees (68%) with percutaneous injuries (86%) during the thoracotomy (73%). Full precautions were utilized in only 46% of exposed providers, while multiple variable logistic regression determined that each personal protective equipment item utilized during EDT correlated with a 34% decreased risk of occupational exposure (odds ratio, 0.66; 95% CI, 0.48-0.91; p = 0.010). CONCLUSIONS: Our results suggest that the risk of occupational exposure should not deter providers from performing EDT. Despite the small risk of viral transmission, our data revealed practices that may place health care providers at unnecessary risk of occupational exposure. Regardless of the lifesaving nature of the procedure, improved universal precaution compliance with personal protective equipment is paramount and would further minimize occupational exposure risks during EDT. LEVEL OF EVIDENCE: Therapeutic/care management study, level III.

The Clinical Impact of Cardiology Consultation Prior to Major Vascular Surgery.

OBJECTIVE: To understand statewide variation in preoperative cardiology consultation prior to major vascular surgery and to determine whether consultation was associated with differences in perioperative myocardial infarction (poMI). SUMMARY BACKGROUND DATA: Medical consultation prior to major vascular surgery is obtained to reduce perioperative risk. Despite perceived benefit of preoperative consultation, evidence is lacking specifically for major vascular surgery on the effect of preoperative cardiac consultation. METHODS: Patient and clinical data were obtained from a statewide vascular surgery registry between January 2012 and December 2014. Patients were risk stratified by revised cardiac risk index category and compared poMI between patients who did or did not receive a preoperative cardiology consultation. We then used logistic regression analysis to compare the rate of poMI across hospitals grouped into quartiles by rate of preoperative cardiology consultation. RESULTS: Our study population comprised 5191 patients undergoing open peripheral arterial bypass (n = 3037), open abdominal aortic aneurysm repair (n = 332), or endovascular aneurysm repair (n = 1822) at 29 hospitals. At the patient level, after risk-stratification by revised cardiac risk index category, there was no association between cardiac consultation and poMI. At the hospital level, preoperative cardiac consultation varied substantially between hospitals (6.9%-87.5%, P <0.001). High preoperative consulting hospitals (rate >66%) had a reduction in poMI (OR, 0.52; confidence interval: 0.28-0.98; P <0.05) compared with all other hospitals. These hospitals also had a statistically greater consultation rate with a variety of medical specialties. CONCLUSIONS: Preoperative cardiology consultation for vascular surgery varies greatly between institutions, and does not appear to impact poMI at the patient level. However, reduction of poMI was noted at the hospitals with the highest rate of preoperative cardiology consultation as well as a variety of medical services, suggesting that other hospital culture effects play a role.
