BACKGROUND: Sports-related concussion has received increasing awareness due to short- and long-term neurologic sequelae seen among athletes. The King-Devick (K-D) test captures impairment of eye movements and other correlates of suboptimal brain function. We investigated the K-D test as a screening for concussion when administered by layperson sports parents in a cohort of amateur boxers. METHODS: The K-D test was administered pre-fight and post-fight by laypersons masked to the head trauma status of each athlete. Matches were watched over by a ringside physician and boxing trainer. Athletes with suspected head trauma received testing with the Military Acute Concussion Evaluation (MACE) by the ringside physician to determine concussion status. Athletes sustaining concussion were compared to the athletes screened using the K-D test. RESULTS: Post-fight K-D scores were lower (better) than the best baseline score (41 vs. 39.3 s, P=0.34, Wilcoxon signed-rank test), in the absence of concussion. One boxer sustained a concussion as determined by the ringside physician. This boxer was accurately identified by the layperson K-D testers due to a worsening in K-D test compared to baseline (3.2 seconds) and an increased number of errors. High levels of test-retest reliability were observed (intraclass correlation coefficient 0.90 [95% CI 0.84-0.97]). Additionally, 6 boxers who participated in multiple bouts showed no worsening of their K-D times further supporting that scores are not affected by the fatigue associated with sparring. CONCLUSION: The K-D test is a rapid sideline screening tool for concussion that can be effectively administered by non-medically trained laypersons.

BACKGROUND: Industrialization in the northwest provinces of the People's Republic of China is accelerating rapid increases in early life environmental exposures, yet no publications have assessed health care provider capacity to manage common hazards. METHODS: To assess provider attitudes and beliefs regarding the environment in children's health, determine self-efficacy in managing concerns, and identify common approaches to managing patients with significant exposures or environmentally-mediated conditions, a two-page survey was administered to pediatricians, child care specialists, and nurses in five provinces (Gansu, Shaanxi, Xinjiang, Qinghai, and Ningxia). Descriptive and multivariable analyses assessed predictors of strong self-efficacy, beliefs or attitudes. RESULTS: 960 surveys were completed with <5% refusal; 695 (72.3%) were valid for statistical analyses. The role of environment in health was rated highly (mean 4.35 on a 1-5 scale). Self-efficacy reported with managing lead, pesticide, air pollution, mercury, mold and polychlorinated biphenyl exposures were generally modest (2.22-2.52 mean). 95.4% reported patients affected with 11.9% reporting seeing >20 affected patients. Only 12.0% reported specific training in environmental history taking, and 12.0% reported owning a text on children's environmental health. Geographic disparities were most prominent in multivariable analyses, with stronger beliefs in environmental causation yet lower self-efficacy in managing exposures in the northwestern-most province. CONCLUSIONS: Health care providers in Northwest China have strong beliefs regarding the role of environment in children's health, and frequently identify affected children. Few are trained in environmental history taking or rate self-efficacy highly in managing common hazards. Enhancing provider capacity has promise for improving children's health in the region.

A major focus in urologic research is the identification of new biomarkers with improved specificity for clinically-significant prostate cancer. A promising new test based on prostate-specific antigen (PSA) is called the Prostate Health Index (PHI), which has recently been approved in the United States, Europe and Australia. PHI is a mathematical formula that combines total PSA, free PSA and [-2] proPSA. Numerous international studies have consistently shown that PHI outperforms its individual components for the prediction of overall and high-grade prostate cancer on biopsy. PHI also predicts the likelihood of progression during active surveillance, providing another noninvasive modality to potentially select and monitor this patient population. This article reviews the evidence on this new blood test with significant promise for both prostate cancer screening and treatment decision-making.

The time required to conduct drug and alcohol screening has been a major barrier to its implementation in mainstream healthcare settings. Because patient self-administered tools are potentially more efficient, we translated the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) into an audio guided computer assisted self interview (ACASI) format. This study reports on the test-retest reliability of the ACASI ASSIST in an adult primary care population. Adult primary care patients completed the ACASI ASSIST, in English or Spanish, twice within a 1-4week period. Among the 101 participants, there were no significant differences between test administrations in detecting moderate to high risk use for tobacco, alcohol, or any other drug class. Substance risk scores from the two administrations had excellent concordance (90-98%) and high correlation (ICC 0.90-0.97) for tobacco, alcohol, and drugs. The ACASI ASSIST has good test-retest reliability, and warrants additional study to evaluate its validity for detecting unhealthy substance use.

BACKGROUND AND OBJECTIVES: This analysis aims to: (1) compare induction experiences among participants who self-reported using one of the four most commonly reported POs, and (2) examine factors associated with difficult bup-nx induction. Our hypothesis, based on previous research and current guidelines, is that those on longer-acting opioids will have experienced more difficult inductions. METHODS: The Prescription Opioid Addiction Treatment Study (POATS) was a multi-site, randomized clinical trial, using a two-phase adaptive treatment research design. This analysis examines bup-nx induction of participants who self-reported primary PO use of methadone, ER-oxycodone, IR-oxycodone, and hydrocodone (n = 569). Analyses examined characteristics associated with difficult induction, defined as increased withdrawal symptoms measured by the Clinical Opiate Withdrawal Scale (COWS) after the first bup-nx dose with higher scores denoting greater withdrawal symptoms/severity. RESULTS: Contrary to our hypothesis, difficult induction experiences did not differ by primary PO type. Those who experienced a post-induction increase in COWS score had lower pre-dose COWS scores compared to those who did not experience a post-induction increase in COWS score (10.09 vs. 12.77, t(624) = -13.56, p < .001). Demographics characteristics, depression, and pain history did not predict a difficult induction. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: Difficult bup-nx inductions were not associated with participants' primary PO. Severity of withdrawal, measured with the COWS, was an important variable, reminding clinicians that bup-nx should not be commenced prior to evidence of moderate opioid withdrawal. These findings add to the evidence that with careful procedures, bup-nx can used with few difficulties in PO-dependent patients. (Am J Addict 2013;XX:000-000).

Optimizing the health of populations, whether defined as persons receiving care from a health care delivery system or more broadly as persons in a region, is emerging as a core focus in the era of health care reform. To achieve this goal requires an approach in which preventive care is valued and "nonmedical" determinants of patients' health are engaged. For large, multimission systems such as academic medical centers, navigating the evolution to a population-oriented paradigm across the domains of patient care, education, and research poses real challenges but also offers tremendous opportunities, as important objectives across each mission begin to align with external trends and incentives. In clinical care, opportunities exist to improve capacity for assuming risk, optimize community benefit, and make innovative use of advances in health information technology. Education must equip the next generation of leaders to understand and address population-level goals in addition to patient-level needs. And the prospects for research to define strategies for measuring and optimizing the health of populations have never been stronger. A remarkable convergence of trends has created compelling opportunities for academic medical centers to advance their core goals by endorsing and committing to advancing the health of populations.

In October 2012, Bellevue Hospital Center (Bellevue) in New York City was temporarily closed as a result of Hurricane Sandy, the largest hurricane in US history. Bellevue's primary care office-based buprenorphine program was temporarily closed and later relocated to an affiliate public hospital. Previous research indicates that the relationships between disaster exposure, substance use patterns, psychiatric symptoms, and mental health services utilization is complex, with often conflicting findings regarding post-event outcomes (on the individual and community level) and antecedent risk factors. In general, increased use of tobacco, alcohol, and illicit drugs is associated with both greater disaster exposure and the development or exacerbation of other psychiatric symptoms and need for treatment. To date, there is limited published information regarding post-disaster outcomes among patients enrolled in office-based buprenorphine treatment, as the treatment modality has only been relatively approved recently. Patients enrolled in the buprenorphine program at the time of the storm were surveyed for self-reported buprenorphine adherence and illicit substance and alcohol use, as well as disaster-related personal consequences and psychiatric sequelae post-storm. Baseline demographic characteristics and insurance status were available from the medical record. Analysis was descriptive (counts and proportions) and qualitative, coding open-ended responses for emergent themes. There were 132 patients enrolled in the program at the time of the storm; of those, 91 were contacted and 89 completed the survey. Almost half of respondents reported disruption of their buprenorphine supply. Unexpectedly, patients with psychiatric comorbidity were no more likely to report increased use/relapse as a result. Rather, major risk factors associated with increased use or relapse post-storm were: (1) shorter length of time in treatment, (2) exposure to storm losses such as buprenorphine supply disruption, (3) a pre-storm history of red flag behaviors (in particular, repeat opioid-positive urines), and (4) new-onset post-storm psychiatric symptoms. Our findings highlight the relative resilience of buprenorphine as an office-based treatment modality for patients encountering a disaster with associated unanticipated service disruption. In responding to future disasters, triaging patient contact and priority based on a history of red-flag behaviors, rather than a history of psychiatric comorbidity, will likely optimize resource allocation, especially among recently enrolled patients. Additionally, patients endorsing new-onset psychiatric manifestations following disasters may be an especially high-risk group for poor outcomes, warranting further study.

Object Civilian gunshot wounds to the head (GSWH) are often deadly, but some patients with open cranial wounds need medical and surgical management and are potentially good candidates for acceptable functional recovery. The authors analyzed predictors of favorable clinical outcome (Glasgow Outcome Scale scores of 4 and 5) after GSWH over a 24-month period. Methods The authors posited 2 questions: First, what percentage of civilians with GSWH died in the state of Maryland in a given period of time? Second, what were the predictors of favorable outcome after GSWH? The authors examined demographic, clinical, imaging, and acute care data for 786 civilians who sustained GSWH. Univariate and logistic regression analyses were used to analyze the data. Results Of the 786 patients in this series, 712 (91%) died and 74 (9%) completed acute care in 9 trauma centers. Of the 69 patients admitted to one Maryland center, 46 (67%) eventually died. In 48 patients who were resuscitated, the Injury Severity Score was 26.2, Glasgow Coma Scale (GCS) score was 7.8, and an abnormal pupillary response (APR) to light was present in 41% of patients. Computed tomography indicated midline shift in 17%, obliteration of basal cisterns in 41.3%, intracranial hematomas in 34.8%, and intraventricular hemorrhage in 49% of cases. When analyzed for trajectory, 57.5% of bullet slugs crossed midcoronal, midsagittal, or both planes. Two subsets of admissions were studied: 27 patients (65%) who had poor outcome (25 patients who died and 2 who had severe disability) and 15 patients (35%) who had a favorable outcome when followed for a mean period of 40.6 months. Six patients were lost to follow-up. Univariate analysis indicated that admission GCS score (p < 0.001), missile trajectory (p < 0.001), surgery (p < 0.001), APR to light (p = 0.002), patency of basal cisterns (p = 0.01), age (p = 0.01), and intraventricular bleed (p = 0.03) had a significant relationship to outcome. Multivariable logistic regression analysis indicated that GCS score and patency of the basal cistern were significant determinants of outcome. Exclusion of GCS score from the regression models indicated missile trajectory and APR to light were significant in determining outcome. Conclusions Admission GCS score, trajectory of the missile track, APR to light, and patency of basal cisterns were significant determinants of outcome in civilian GSWH.

Recent changes in the global climate system have resulted in excess mortality and morbidity, particularly among susceptible individuals with preexisting cardiopulmonary disease. These weather patterns are projected to continue and intensify as a result of rising CO2 levels, according to the most recent projections by climate scientists. In this Pulmonary Perspective, motivated by the American Thoracic Society Committees on Environmental Health Policy and International Health, we review the global human health consequences of projected changes in climate for which there is a high level of confidence and scientific evidence of health effects, with a focus on cardiopulmonary health. We discuss how many of the climate-related health effects will disproportionally affect people from economically disadvantaged parts of the world, who contribute relatively little to CO2 emissions. Last, we discuss the financial implications of climate change solutions from a public health perspective and argue for a harmonized approach to clean air and climate change policies.

BACKGROUND: Organizational culture is an important but underinvestigated feature of the work environment that can impact provider behavior, including adherence to clinical practice guidelines. There is substantial evidence that physician assistance to smokers can produce significant reductions in tobacco use. However, this evidence has not been well translated into practice, as only a small proportion of smokers receive recommended treatment during medical visits. PURPOSE: This study examines organizational culture as a contextual feature of primary care clinics and its impact on adherence to evidence-based guidelines for treating tobacco use. METHODOLOGY: Cross-sectional survey data were collected from 500 primary care providers in 60 community clinics located in New York City. Relationships between provider adherence to "5A" clinical guidelines, as recommended by the U.S. Public Health Service, and both provider and organizational covariates were described. We used hierarchical linear modeling to examine the associations between clinic culture and provider treatment patterns. FINDINGS: Providers in clinics with stronger "group/clan," "hierarchical," and "rational" culture types, as compared with a "developmental" culture, reported greater adherence to 5A guidelines (p < .05). System-level structures and care processes were positively associated (p < .01), whereas number of ongoing quality initiatives was negatively associated with 5A delivery (p < .05). Provider familiarity with guidelines (p < .01), confidence with cessation counseling (p < .05), and perceived effectiveness in helping smokers quit were associated with more frequent 5A intervention (p < .01). PRACTICE IMPLICATIONS: Findings suggest that organizational culture can influence provider adherence to cessation treatment guidelines, even when controlling for other factors known to affect practice patterns. Specifically, cultures that emphasize human resources and performance standards are conducive to integrating 5A guidelines into routine practice. Understanding the role of organizational culture enables healthcare managers and practitioners to be strategic when implementing, and also sustaining, use of evidence-based guidelines.
