Shocking Study Reveals That Only 6.9% of People With Mental Health Disorders Get Effective Treatment
Only 6.9% of people with mental health or substance use disorders receive effective treatment, largely due to lack of recognition and inadequate care. A global study highlights the need for better-trained general practitioners and policy-driven mental health investments.
A new study estimates that globally, only 6.9% of individuals with mental health or substance use disorders receive effective treatment.
Researchers from the University of British Columbia and Harvard Medical School analyzed survey data from nearly 57,000 participants across 21 countries over a 19-year period. Their findings provide the most comprehensive insight yet into where people disengage from the path to effective treatment for nine common anxiety, mood, and substance use disorders.
The study identified the greatest barrier to treatment as a lack of recognition that help is needed. However, even among those who seek medical care, many do not receive effective treatment.
Lack of Data-Driven Policy in Mental Health
“This survey data has allowed us to create the only effective treatment indicator that exists for mental health and substance use,” said lead author Dr. Daniel Vigo, associate professor at UBC’s department of psychiatry and school of population and public health. “Policy decisions and allocative decisions for funding should be guided by data, and this hasn’t always been the case in the realm of mental health and substance use.”
The World Health Organization-World Mental Health Surveys Initiative collects data on the prevalence, severity, and treatment of mental disorders worldwide. This study focused on survey participants who met the criteria for a disorder under the Diagnostic and Statistical Manual of Mental Disorders-IV, a standardized classification system used by mental health professionals from 1994 to 2013.
Where Patients Drop Off in the Treatment Process
The team, led by Dr. Vigo and Dr. Ronald Kessler of Harvard, was interested in how close participants got to receiving effective treatment that met evidence-based guidelines—and where they might have dropped off along the way.
They analyzed four key steps, and the percentage of people who proceeded from each step to the next:
- Recognize their need for treatment
- Make contact with the healthcare system about it
- Receives a minimum level of adequate treatment
- Receives effective treatment
They found:
- Only 46.5 percent of people who met the criteria for a disorder recognized their need for treatment.
- Of those who did recognize their need, only 34.1 percent turned to the medical system for help.
- Most who sought help (82.9 percent) received a minimum level of adequate treatment.
- About 47 percent of people who received minimally adequate treatment ended up receiving effective treatment.
Attrition at various points along this pathway meant that only 6.9 percent ended up receiving effective treatment.
Bottlenecks in the Healthcare System
“Understanding where the bottlenecks are for each of these disorders provides a unique and previously unavailable blueprint for decision makers to understand problems objectively and try to adjust the system,” said Dr. Vigo.
The study revealed a significant drop-off after patients contacted the healthcare system but before they received effective treatment. Since general practitioners and family doctors are typically their first point of contact with the system, it’s essential to make sure those doctors have appropriate training, said Dr. Vigo.
“Improving the ability of these general practitioners and family doctors to diagnose and treat the mild to moderate forms, and to know when to refer more severely affected folks to specialists, becomes the cornerstone of the system,” he said.
The research provides decision-makers with a base of evidence to guide policy and funding decisions in mental health and substance use. By highlighting gaps in service needs and outcomes for disorders ranging from bipolar disorders to addiction, it identifies where targeted investments could potentially yield the greatest impact. Armed with these insights, policymakers worldwide can prioritize interventions that result in improvements in care.
