Medical Occupational Health Consulting Services

Occupational Health is the promotion and maintenance, to the highest degree, of physical, mental, and social well-being of workers in all occupations by promoting the healthiest environment possible, controlling risks, and adapting work to people and people to their jobs. Occupational Health and Safety Consultants analyze many types of work environments and work procedures. Consultants inspect workplaces for adherence to regulations on safety, health, and the environment. They also design programs to prevent illness and injury to workers and damage to the environment.

MDOHC is concerned with keeping people well at work — physically and mentally. This includes advising about workplace safety and the prevention of occupational injuries and illness, assessing fitness for work, and helping rehabilitate employees who have suffered injury or sickness back into work. MDOHC’s services are also used to assist organizations in managing absence situations, both short and long term.

Being out of work has significant, negative effects on the physical and mental health of individuals. There is good evidence that getting back to work not only improves self-esteem but also aids recovery and rehabilitation for the person. Forty million working days are lost every year to occupational poor health. A third of people claiming incapacity benefit have come from work.

MDOHC is, therefore, important for the economy, for society, and for the individual.

Primary Responsibilities of MDOHC Consultants

  • Focus on the prevention, evaluation, treatment, and resolution of health conditions caused by the workplace environment

  • Assess the origin of worker injury and illness, taking past history, work conditions, and other factors into consideration so that injuries and illnesses are properly classified and treated appropriately to ensure workers’ safe return to work

  • Manage and monitor the health of employees and improve their well-being through health promotion and education in the workplace

  • Address business-related issues for medical facilities and healthcare providers so they can prioritize providing care

  • Gather and analyze data and then draw conclusions and present findings in the form of recommendations to their clients

  • Help doctors or healthcare facilities with a range of regulatory issues, such as complying with insurance and safety plans, keeping patient information confidential, and disposing of hazardous waste

  • Suggest ways that a client can lower exposure to malpractice lawsuits or address such lawsuits when they come up

  • Improve the human condition at the macro level, one business at a time

  • Use critical thinking and problem solving skills to identify an issue or apply medical knowledge in industries that are not led by physicians

  • Focus around the industry-client relationship
