Arsenic Exposure, Assessment, Toxicity, Diagnosis, and Management: Guidance for Occupational and Environmental Physicians.

: Arsenic is ubiquitous in the environment and human exposure can occur from multiple possible routes including diet. Occupational medicine physicians asked to evaluate workers with elevated urine arsenic levels may be unaware that many sources of arsenic exposure are not work related. In this paper, we address arsenic exposure sources and pathways, adverse health effects of arsenic exposure and those subpopulations at increased risk, and the evaluation and treatment of those exposed to elevated arsenic levels.

Occupational Noise-Induced Hearing Loss.

: Occupational hearing loss is preventable through a hierarchy of controls, which prioritize the use of engineering controls over administrative controls and personal protective equipment. The occupational and environmental medicine (OEM) physician plays a critical role in the prevention of occupational noise-induced hearing loss (NIHL). This position statement clarifies current best practices in the diagnosis of occupational NIHL.

Responsibilities of the Occupational and Environmental Medicine Provider in the Treatment and Prevention of Climate Change-Related Health Problems.

: Workers are uniquely susceptible to the health hazards imposed by environmental changes. Occupational and environmental medicine (OEM) providers are at the forefront of emerging health issues pertaining to working populations including climate change, and must be prepared to recognize, respond to, and mitigate climate change-related health effects in workers. This guidance document from the American College of Occupational and Environmental Medicine focuses on North American workers health effects that may occur as a result of climate change and describes the responsibilities of the OEM provider in responding to these health challenges.

Fitness-for-Duty Assessments of Industrial Firefighters: Guidance for Occupational Medicine Physicians.

: Industrial firefighters share many characteristics with municipal firefighters; however, employers frequently have not addressed or characterized the unique job duties, hazards, and specific physical/mental demands associated with industrial firefighting. In addition, gaps exist in the medical literature with regard to industrial firefighter demographics, behavioral risk factors, and chronic diseases. Finally, the proper methodologies for fitness-for-duty assessment of employees acting in this capacity are lacking. To address these gaps, the American College of Occupational and Environmental Medicine (ACOEM) convened a Task Force in 2014, to develop fitness-for-duty guidance for industrial firefighters. This document highlights these gaps and suggests research opportunities to enhance the health and safety of this population. While an extensive literature review found a lack of studies for this population-thus excluding the development of an evidence-based document-sufficient materials were available from which to draw preliminary conclusions, considerations for best practices, and recommendations for future studies.

S1 guideline on occupational skin products: protective creams, skin cleansers, skin care products (ICD 10: L23, L24)--short version.

Job-related hand dermatitis heads up the list of reported occupational diseases. So-called skin products - understood to mean protective creams, skin cleansers and skin care products - are used for the primary and secondary prevention of job- related hand dermatitis. In the interests of evidence-based medicine, the only preventive measures and/or occupational skin products that should be used are those whose potential uses and efficacy are underpinned by scientific research. To this end, the Arbeitsgemeinschaft für Berufs- und Umweltdermatologie e.V. (Working Group for Occupational and Environmental Dermatology, ABD) of the DDG (German Dermatological Society) and the Deutsche Gesellschaft für Arbeits- und Umweltmedizin (German Society for Occupational and Environmental Medicine, DGAUM) have summed up the latest scientific findings and recommendations in the updated guideline. The benefit of the combined application of protective creams and skin care products in the primary and secondary prevention of work-related contact dermatitis has been widely confirmed by recent clinical-epidemiological studies. The guideline clearly explains the necessity of demonstrating the efficacy of protective creams and cleansing products by means of in vivo methods in the sense of repetitive applications. Transferable standardised testing systems designed to examine the irritation potential and thus the compatibility of occupational skin cleansers and the reduction of irritation by protective skin creams have now been developed and validated by multicentre studies for skin protection creams and cleansers. The status of the current assessment of the safety of occupational skin products is also summarised.

[Standardization of spirometry: 2015 update. Published by German Atemwegsliga, German Respiratory Society and German Society of Occupational and Environmental Medicine]. / Leitlinie zur Spirometrie. Leitlinie der Deutschen Atemwegsliga, der Deutschen Gesellschaft für Pneumologie und Beatmungsmedizin und der Deutschen Gesellschaft für Arbeitsmedizin und Umweltmedizin zur Spirometrie.

Spirometry is a simple test and considered the gold standard in lung function. An obstructive ventilatory defect is a disproportionate reduction of maximal airflow from the lung in relation to the maximal volume that can be displaced from the lung. It implies airway narrowing and is defined by a reduced FEV1/FVC ratio below the 5th percentile of the predicted value (lower limit of normal, LLN). A restrictive disorder may be suspected when vital capacity (FVC) is reduced and FEV1/FVC is normal. It is definitely proven, however, only by a decrease in TLC below the 5th percentile of predicted value (LLN). The measurement of TLC by body plethysmography is necessary to confirm or exclude a restrictive defect or hyperinflation of the lung when FVC is below the LLN. 2012 a task force of the ERS published new reference values based on 74,187 records from healthy non-smoking males and females from 26 countries. The new reference equations for the 3-95 age range are now available that include appropriate age-dependent mean values and lower limits of normal (LLN). This presentation aims at providing the reader with recommendations dealing with standardization and interpretation of spirometry.

ACOEM practice guidelines: opioids and safety-sensitive work.

OBJECTIVE: ACOEM has updated the treatment guidelines concerning opioids. This report highlights the safety-sensitive work recommendation that has been developed. METHODS: Comprehensive literature reviews were accomplished with article abstraction, critiquing, grading, evidence table compilation, and guideline finalization by a multidisciplinary expert panel to develop evidence-based guidance. A total of 12 moderate-quality studies were identified to address motor vehicle crash risk, and none regarding other work among opioid-using patients. RESULTS: Acute or chronic opioid use is not recommended for patients who perform safety-sensitive jobs. These jobs include operating motor vehicles, other modes of transportation, forklift driving, overhead crane operation, heavy equipment operation and tasks involving high levels of cognitive function and judgment. CONCLUSION: Quality evidence consistently demonstrates increased risk of vehicle crashes and is recommended as the surrogate for other safety-sensitive work tasks.

[Efficacy and appropriateness in updating and validating the activities of the occupational health physician]. / Strumenti di aggiornamento ed orientamento delle attività del medico del lavoro, efficacia ed appropriatezza.

BACKGROUND: We reviewed the Italian tools for updating and validating the activities of occupational health physicians (guidelines, consensus documents, technology assessment, good practices, etc.) from the point of view of efficacy and appropriateness. RESULTS AND CONCLUSIONS: We examined more than 20 guidelines produced since 2003 by the Italian Society of Occupational Health and Industrial Hygiene (SIMLII), the procedures issued by the National System of Guidelines in Medicine/SNLG) by the Italian National Health Institute (ISS) and the new law on occupational safety and health "Decreto Legislativo 81/08", which for the first time includes and defines in specific legislation the different possible instruments for guiding the activities of the occupational health physician, not only to improve the effectiveness of interventions but also aimed at constantly adopting rigorous methodologies based on evidence.

Reassessment of evidence synthesis of occupational medicine practice guidelines for interventional pain management.

BACKGROUND: Appropriately developed practice guidelines present statements of best practice based on a thorough evaluation of the evidence from published studies on the outcomes of treatments, which include the application of multiple methods for collecting and evaluating evidence for a wide range of clinical interventions and disciplines. However, the guidelines are neither infallible, nor a substitute for clinical judgment. While the guideline development process is a complex phenomenon, conflict of interest in guideline development and inappropriate methodologies must be avoided. It has been alleged that the guidelines by the American College of Occupational and Environmental Medicine (ACOEM) prevent injured workers from receiving the majority of medically necessary and appropriate interventional pain management services. An independent critical appraisal of both chapters of the ACOEM guidelines showed startling findings with a conclusion that these guidelines may not be applied in patient care as they scored below 30% in the majority of evaluations utilizing multiple standardized criteria. OBJECTIVE: To reassess the evidence synthesis for the ACOEM guidelines for the low back pain and chronic pain chapters utilizing an expanded methodology, which includes the criteria included in the ACOEM guidelines with the addition of omitted literature and application of appropriate criteria. METHODS: For reassessment, randomized trials were utilized as it was in the preparation of the guidelines. In this process, quality of evidence was assessed and recommendations were made based on grading recommendations of Guyatt et al. The level of evidence was determined utilizing the quality of evidence criteria developed by the U.S. Preventive Services Task Force (USPSTF), as well as the outdated quality of evidence criteria utilized by ACOEM in the guideline preparation. Methodologic quality of each individual article was assessed utilizing the Agency for Healthcare Research and Quality (AHRQ) methodologic assessment criteria for diagnostic interventions and Cochrane methodologic quality assessment criteria for therapeutic interventions. RESULTS: The results of reassessment are vastly different from the conclusions derived by the ACOEM guidelines. The differences in strength of rating for the diagnosis of discogenic pain by provocation discography and facet joint pain by diagnostic facet joint nerve blocks is established with strong evidence. Therapeutic cervical and lumbar medial branch blocks and radiofrequency neurolysis, therapeutic thoracic medial branch blocks, cervical interlaminar epidural steroid injections, caudal epidural steroid injections, lumbar transforaminal epidural injections, percutaneous and endoscopic adhesiolysis, and spinal cord stimulation qualified for moderate to strong evidence. Additional insight is also provided for evidence rating for intradiscal electrothermal therapy (IDET), automated percutaneous disc decompression, and intrathecal implantables. CONCLUSION: The reassessment and reevaluation of the low back and chronic pain chapters of the ACOEM guidelines present results that are vastly different from the published and proposed guidelines. Contrary to ACOEM's conclusions of insufficient evidence for most interventional techniques, the results illustrate moderate to strong evidence for most diagnostic and therapeutic interventional techniques.

A critical appraisal of 2007 American College of Occupational and Environmental Medicine (ACOEM) Practice Guidelines for Interventional Pain Management: an independent review utilizing AGREE, AMA, IOM, and other criteria.

BACKGROUND: Today, with the growing interest of the medical community and others in practice guidelines, there is greater emphasis on formal procedures and methods for arriving at a widely scrutinized and endorsed consensus than ever before. Conflicts in terminology and technique are notable for the confusion that guidelines create and for what they reflect about differences in values, experiences, and interests among different parties. While public and private development activities continue to multiply, the means for coordinating these efforts to resolve inconsistencies, fill in gaps, track applications and results, and assess the soundness of particular guidelines continue to be limited. In this era of widespread guideline development by private organizations, the American College of Occupational and Environment Medicine (ACOEM) has developed guidelines that evaluate areas of clinical practice well beyond the scope of occupational medicine and yet fail to properly involve physicians expert in these, especially those in the field of interventional pain management. As the field of guidelines suffers from imperfect and incomplete scientific knowledge as well as imperfect and uneven means of applying that knowledge without a single or correct way to develop guidelines, ACOEM guidelines have been alleged to hinder patient care, reduce access to interventional pain management procedures, and transfer patients into a system of disability, Medicare, and Medicaid. OBJECTIVE: To critically appraise occupational medicine practice guidelines for interventional pain management by an independent review utilizing the Appraisal of Guidelines for Research and Evaluation (AGREE), American Medical Association (AMA), Institute of Medicine (IOM), and other commonly utilized criteria. METHODS: Revised chapters of ACOEM guidelines, low back pain and chronic pain, developed in 2007 and 2008 are evaluated, utilizing AGREE, AMA, IOM instruments, and Shaneyfelt et al's criteria, were independently reviewed by 4 appraisers. RESULTS: Critical appraisal utilizing the AGREE instrument found that both chapters scored less than 10% in 3 of the 6 domains, less than 20% in one domain, over 30% in one domain, and over 70% in one domain. Global assessment also scored below 30% with a recommendation from AGREE, "not recommended or suitable for use in practice." Based on AMA key attributes, both chapters of ACOEM guidelines met only one of the 6 key attributes, only 3 of the 8 attributes were met by IOM criteria, and based on the criteria described by Shaneyfelt et al, overall only 28% of criteria were met. CONCLUSION: Both the low back pain and chronic pain chapters of the ACOEM guidelines may not be ideal for clinical use based on the assessment by the AGREE instrument, AMA attributes, and criteria established by Shaneyfelt et al. They also scored low on IOM criteria (37.5%). These guidelines may not be applicable for clinical use.
