Establish systematic collaboration with employer agencies and enterprises as effectiveness measures of mental health care systems. However, only around half of people with severe mental disorders are treated, and treatment rates are substantially lower for individuals with milder mental illnesses. This is an important shortcoming, because adequate or enhanced treatment can improve work outcomes. One critical aspect is the involvement of mental health specialists. If seeking treatment, people mostly seek help from general practitioners; only one in four are treated by a specialist. A more extensive use of specialist mental health care, as therapists or consultants to other health care providers, would improve health care outcomes.
