词条 | Workplace health surveillance |
释义 |
The concept is new to occupational health and is frequently confused with medical screening. Health screening refers to the early detection and treatment of diseases associated with particular occupations, while workplace health surveillance refers to the removal of the causative factors. AspectsMedical surveillanceThe mission of a medical surveillance program is to keep workers healthy and ensure that employers are meeting OSHA standards in health and safety.[4] Medical surveillance has an emphasis on prevention: it is designed to detect potential workplace hazards before irreversible health effects can occur.[5] Clinicians with expertise in occupational health, industrial exposures, and respiratory protection screen workers with physical examinations, blood testing, spirometry (a measurement lung function), and audiometry. Screenings are performed at set intervals, often annually. The clinicians providing medical surveillance services include board-certified occupational and environmental medicine physicians, mid-level practitioners, nurses, and NIOSH-certified spirometry technicians.[4][5] Medical surveillance targets actual health events or a change in a biologic function of an exposed person or persons. Medical surveillance is a second line of defense behind the implementation of direct hazard controls such as engineering controls, administrative controls, and personal protective equipment. NIOSH recommends the medical surveillance of workers when they are exposed to hazardous materials. The elements of a medical surveillance program generally include the following:[6]
When the purpose of a medical surveillance program is to detect early signs of work-related illness and disease, it is considered a type of medical screening, to detect preclinical changes in organ function or changes before a person would normally seek medical care and when intervention is beneficial The establishment of a medical screening program should follow established criteria, and specific disease endpoints must be able to be determined by the test selected.[6] Medical examinations and tests are used in many workplaces to determine whether an employee is able to perform the essential functions of the job. Medical surveillance of workers is also required by law in the United States when there is exposure to a specific workplace hazard, and OSHA has a number of standards that require medical surveillance of workers In addition to substance-specific standards, OSHA has standards with broader applicability. For example, employers must follow the medical evaluation requirements of OSHA’s respiratory protection standard ({{CodeFedReg|29|1910|134}}) when respirators are necessary to protect worker health. Likewise, the OSHA standard for occupational exposure to hazardous chemicals in laboratories ({{CodeFedReg|29|1910|1450}}) requires medical consultation following the accidental release of hazardous chemicals. NIOSH also recommends medical surveillance, including screening, of workers when there is exposure to certain occupational hazards.[6] Hazard surveillanceHazard surveillance involves identifying potentially hazardous practices or exposures in the workplace and assessing the extent to which they can be linked to workers, the effectiveness of controls, and the reliability of exposure measures. Workplace hazards can be chemical, biological, physical, ergonomic, psychosocial, or safety-related in nature.[7] Hazard surveillance is an essential component of any occupational health surveillance effort and is used for defining the elements of the risk management program. Critical elements of a risk management program include recognizing potential exposures and taking appropriate actions to minimize them (for example, implementing engineering controls, employing good work practices, and using personal protective equipment). Hazard surveillance should include the identification of work tasks and processes that involve the production and use of hazardous materials, and should be viewed as one of the most critical components of any risk management program.[6] Hazard surveillance includes elements of hazard and exposure assessment. The hazard assessment involves reviewing the best available information concerning toxicity of materials. Such an assessment may come from databases, texts, and published literature or available regulations or guidelines. Human studies, such as epidemiologic investigations and case series or reports, and animal studies may also provide valuable information. The exposure assessment involves evaluating relevant exposure routes (inhalation, ingestion, dermal, and/or injection), amount, duration, and frequency (i.e., dose), as well as whether exposure controls are in place and how protective they are. When data are not available, this will be a qualitative process.[1] Occupational Health Indicators (OHIs)In 1998, the Council of State and Territorial Epidemiologists (CSTE) joined the CDC's National Institute for Occupational Safety and Health (NIOSH) to form the Occupational Health Surveillance Work Group in order to prioritize occupational health conditions to be placed under surveillance.[8] The Work Group recommended that states use 19 occupational health indicators based on the availability of easily obtainable statewide data, the public health importance of the occupational health effect or exposure, and the potential for intervention activities.[8] These indicators are useful in assessing the ongoing policies and preventive measures but they also have some limitations. Among the major limitations are the underreporting of occupational health disorders, the inability to recognize potential occupational association of the disorder by health care workers, difficulties in attributing diseases with long latency or multiple causes (such as lung cancer) to occupational exposures, exclusion of special populations (such as self-employed or military personnel), and differences between state-specific databases.[8] Data SourcesData for the OHIs come from multiple sources including:
Tools{{Unreferenced section|date=April 2017}}The usefulness of a surveillance tool may depend on what hazards are present in the workplace and the health effects those hazards may cause. For example, hearing tests will be helpful when noise exposures are present, while tests assessing lung function or biomonitoring may be useful when airborne agents are present. It is also important to distinguish between tools using medical surveillance (measuring health effects) and hazard surveillance/exposure assessment (physical measurements of the type and severity of hazard present). Periodic testing, including a baseline exam when an employee is hired, can often help detect a decline in function by comparing previous results. Medical surveillance tools
The Occupational Health Safety Network (OHSN)The [https://www.cdc.gov/niosh/topics/ohsn/ Occupational Health Safety Network (OHSN)] is a secure electronic surveillance system developed by the National Institute for Occupational Safety and Health (NIOSH) to address health and safety risks among health care personnel.[21] Hospitals and other healthcare facilities can upload the occupational injury data they already collect to the secure database for analysis and benchmarking with other de-identified facilities. NIOSH works with OHSN participants in identifying and implementing timely and targeted interventions. OHSN modules currently focus on three high risk and preventable events that can lead to injuries or musculoskeletal disorders among healthcare personnel: sharps injuries; blood and body fluid exposures; musculoskeletal injuries from patient handling activities; slips, trips, and falls; and workplace violence.[21] OHSN enrollment is currently open to all U.S. healthcare facilities. OHSN may be expanded to other industry sectors in the future. Confidentiality of informationMost countries have specific regulations for individual health data, which require that the worker be informed if this information is ever shared with any third party. Occupational Health Records (OHR) have the same protections as any medical record that has confidential health information. Employers must store OHR in a secured area free from unauthorized access, use, or disclosure. Workers should have the right to access this information whenever they wish.
