Recurrent traumatic brain injury

This article reviews, analyses and provides commentary on the most recent literature concerning recurrent traumatic brain injury (RTBI) case histories. It is revealed that a significant proportion of TBI sufferers survive and recover most of the functions of daily living. However, relatively little is known about the epidemiology, effects, or causes of a new phenomenon: recurrent TBI.

Thermographic observations in unilateral carpal tunnel syndrome: Report of 61 cases

This study was undertaken to assess the sensitivity and specificity of thermographic diagnosis of unilateral carpal tunnel syndrome in a patient population large enough to permit meaningful statistical analysis. Sixty-one persons with clinical diagnoses of unilateral carpal tunnel syndrome confirmed by electrodiagnostic examination and 40 symptom-free volunteers underwent standard thermographic examinations. The thermographic images were then randomly sorted and interpreted by an experienced physician thermographer. Fifty-seven of the 61 patients with carpal tunnel syndrome were found to have thermographic abnormalities, while only one of the control group was found to have such an abnormality. Individual area sensitivity was highest in the dorsal area, but addition of other regions increased this measure; specificity ranged between 98% and 100%. These findings would appear to confirm the value of thermography in the diagnosis of unilateral carpal tunnel syndrome.

Disparities in work‐related injuries associated with worker compensation coverage status

BACKGROUND This exploratory study addresses patterns of injury in an emerging population of contingent workers who are not covered by either workers compensation (WC) or health insurance. The primary purpose is to improve the information base regarding the entire population of uninsured, injured workers. Because Latino workers are over-represented in the uninsured group, we include additional characterization of their patterns of injury. Recent studies have found that worker compensation claims and reports address a shrinking proportion of occupational injury and exposure, and about two-thirds of occupational injuries are not captured in the U.S. national surveillance system. METHODS Following the NEISS methodology, a work-relatedness indicator was retrieved for emergency department (ED) visits to an academic health center in fiscal year 2005. RESULTS Twenty percent of self-declared work-related injuries were not associated with self-reported WC coverage. Parametric and non-parametric statistical analysis found several significant disparities in workers without WC. These disparities included a higher proportion of Latinos, workers under age 25, and construction workers. In the uninsured group, Latino workers had a higher proportion of moderate and severe injuries. Nearly all (92 percent) workers without WC also lacked health insurance. Injured low-income workers who lack access to both WC and employer-sponsored health insurance comprise an increasing percentage of the occupationally injured. Our exploratory study found this to be particularly true in high-risk populations. CONCLUSIONS Work-relatedness indicators collected routinely in ED and outpatient settings should be incorporated into standard reporting systems to facilitate more accurate and comprehensive surveillance and better-targeted interventions.

Effects of Premium Increases on Enrollment in SCHIP: Findings from Three States

This study examines the effects of new and higher premiums on SCHIP enrollment in Kansas, Kentucky, and New Hampshire—three states that implemented premium changes in 2003. We used state administrative enrollment records from 2001 to 2004–2005 to track changes in total caseloads, new enrollments, and disenrollment timing in premium-paying categories of SCHIP before and after the premium changes were implemented. Premium hikes were associated with lower caseloads in all three states and with earlier disenrollment in Kentucky and New Hampshire. Premium increases appeared to have greater disenrollment effects for lower-income children in New Hampshire and for nonwhite children in Kentucky.

Heroin and fentanyl overdoses in Kentucky: Epidemiology and surveillance

BACKGROUND The study aims to describe recent changes in Kentuckys drug overdose trends related to increased heroin and fentanyl involvement, and to discuss future directions for improved drug overdose surveillance. METHODS The study used multiple data sources (death certificates, postmortem toxicology results, emergency department [ED] records, law enforcement drug submissions, and prescription drug monitoring records) to describe temporal, geographic, and demographic changes in drug overdoses in Kentucky. RESULTS Fentanyl- and heroin-related overdose death rates increased across all age groups from years 2011 to 2015 with the highest rates consistently among 25-34-year-olds. The majority of the heroin and fentanyl overdose decedents had histories of substantial exposures to legally acquired prescription opioids. Law enforcement drug submission data were strongly correlated with drug overdose ED and mortality data. The 2016 crude rate of heroin-related overdose ED visits was 104/100,000, a 68% increase from 2015 (62/100,000). More fentanyl-related overdose deaths were reported between October, 2015, and September, 2016, than ED visits, in striking contrast with the observed ratio of >10 to 1 heroin-related overdose ED visits to deaths. Many fatal fentanyl overdoses were associated with heroin adulterated with fentanyl; <40% of the heroin overdose ED discharge records listed procedure codes for drug screening. CONCLUSIONS The lack of routine ED drug testing likely resulted in underreporting of non-fatal overdoses involving fentanyl and other synthetic drugs. In order to inform coordinated public health and safety responses, drug overdose surveillance must move from a reactive to a proactive mode, utilizing the infrastructure for electronic health records.

Public health preparedness and response capacity inventory validity study.

The Centers for Disease Control and Preventions Public Health Practice Program Office has issued a Public Health Preparedness and Response Capacity Inventory to help state and local public health systems assess their progress towards achievement of the critical capacities and benchmarks specified in the federal Supplemental Funds for Public Health Preparedness and Response for Bioterrorism. The criterion validity of the capacity inventory was assessed by comparing selected state and local agency responses with documentation provided by the agencies to corroborate their answers. Content validity assessment took the form of a mailed survey that also identified the most important questions from the perspective of a separate set of state and local officials. Responses generally upheld the validity of the capacity inventory, although circumstantial threats to validity were identified in the testing process. The instruments use has been reported to the Centers for Disease Control and Prevention by approximately half the states and over 800 local public health entities. An interactive electronic version includes a scoring mechanism that allows agencies to judge progress towards the critical capacities and benchmarks over time.

Restraint Use in Inpatient Rehabilitation: Incidence, Predictors, and Implications

The use of mechanical restraints in rehabilitation facilities focuses attention on the conflict between patient safety and independent physical function. To evaluate restraint use, we reviewed records of 323 inpatient rehabilitation admissions. Restraint orders were written for 78.3% of admissions, but used in only 32.2% of cases (mean duration of use was 16 days). Posey vests were most commonly used (78.2%). Reasons for restraint were previous fall (26.8%), impulsivity (23.7%), and inappropriate self-transfers (19.6%). Male sex, decreased mental status, low admission functional independence measure (FIM) score, stroke, or traumatic brain injury were closely associated with restraint use. Falls occurred in 25% of restrained and 10.1% of unrestrained patients. Conclusions are as follows: (1) although physician orders are required to apply restraints, nursing staff initiate, monitor, and discontinue restraint use independently; (2) traumatic brain injury or stroke, decreased admission mental status, lower FIM scores, and male sex are indicators of restraint use; (3) age is not associated with restraint use; and (4) restraints may not prevent falls.

Public Health Financial Management Competencies

The absence of appropriate financial management competencies has impeded progress in advancing the field of public health finance. It also inhibits the ability to professionalize this sector of the workforce. Financial managers should play a critical role by providing information relevant to decision making. The lack of fundamental financial management knowledge and skills is a barrier to fulfilling this role. A national expert committee was convened to examine this issue. The committee reviewed standards related to financial and business management practices within public health and closely related areas. Alignments were made with national standards such as those established for government chief financial officers. On the basis of this analysis, a comprehensive set of public health financial management competencies was identified and examined further by a review panel. At a minimum, the competencies can be used to define job descriptions, assess job performance, identify critical gaps in financial analysis, create career paths, and design educational programs.

Using Enforcement and Adjudication Data to Assess the Impact of a Primary Safety Belt Law

Background: Identification of effective implementation strategies for motor vehicle injury prevention law is an important priority for research in public health law and policy. Extensive literature in related fields demonstrates the relationship between enforcement activities and achievement of safety objectives. Purpose: We conducted this study to determine the role of enforcement and adjudication in the implementation of a primary safety belt law, including the level and sustainability of safety belt–related conviction rates, using newly available data from the state judicial administrative authority. A secondary goal was to assess the contribution of the administrative data set to the analysis of the primary safety belt law. Methods: The analysis used an interrupted time series design to evaluate the longitudinal effect of the primary safety belt law implementation in 2007 on safety belt infractions and convictions in Kentucky, 2003–2012. Segmented regression analysis was used to estimate changes in the level and trend of safety belt nonuse conviction rate after the full implementation of the law, while controlling for the baseline level and trend. The association between the safety belt–related conviction rates and other expected outcomes of the laws implementation was studied. Results: Safety belt citations doubled and convictions nearly tripled during the decade studied, most dramatically in the first year. Increases were sustained throughout the study period. There was a strong positive linear association between the safety belt nonuse conviction rate and the observed safety belt use in the state, as well as a strong negative association between the safety belt nonuse conviction rate and the number of nonrestrained motor vehicle crash fatalities. Discussion: Our analysis demonstrates that Kentuckys public safety and judicial systems took the new law seriously and enforced it effectively and that the increased level of enforcement persisted for at least 5 years after implementation. We also find that data from judicial system administrative agency reports make an important contribution to public policy analysis. In the face of persistent antiregulatory forces and public-sector budget cuts, it is critically important to document the relationship between enforcement activities and the achievement of legislative goals.

Coded statutory data sets for evaluation of public health law.

Background and objectives: The evaluation of public health law requires reliable accounts of underlying statutes and regulations. States often enact public health-related statutes with nonuniform provisions, and variation in the structure of state legal codes can foster inaccuracy in evaluating the impact of specific categories of law. The optimal format for empirical analysis is a machine-readable 50-state coded data set. This study provides a comprehensive assessment of these resources and related materials with a focus on statutory data sets. Research design: An exhaustive literature search was followed by a “pearling” or “snowball” approach to assure the most complete inventory of this very diverse and diffuse information. We also interviewed three leading investigators to identify barriers to wider use and availability of coded legal data sets. Results: We identified relatively few accessible coded statutory data sets, and others that are not available for use outside the group or individual that compiled them. The Robert Wood Johnson Foundation-funded Public Health Law Research Program has made funding available for the development and dissemination of additional data sets, as well as extensive guidance regarding their use in the evaluation of public health law. Investigators reported serious obstacles to these activities in the past. Conclusions: Compilation of coded statutory data sets requires a focused investment of resources that has only recently become available. Funders should require grantees to make their work accessible to other investigators so as to assure development of public health law research and evaluation.
