Patients with severe depression show at least as good clinical benefit from 'low-intensity' interventions, such as self help books and interactive websites, as less severely ill patients, according to new research by The University of Manchester.
Depression is a major cause of disability worldwide and effective management of this is a key challenge for health care systems.
The study, funded by the National Institute for Health Research (NIHR), confirmed evidence that 'low-intensity' interventions provide significant clinical benefit. Initial severity of depression is one of the key variables determining who gets 'low' or 'high' intensity treatment, but this is largely based on epidemiological studies and clinical experience rather than high quality evidence.
Researchers from an international collaboration carrid out a meta-analysis of several studies involving 2470 patients with depression, all treated in a non-hospital setting. All studies were from the year 2000 or later with a sample size of more than 50 patients. The mean age in all studies was 35-45, and studies included patients with lower levels of depressive symptoms, as well as those with quite severe depression.
'Low-intensity' treatment was defined as interventions designed to help patients manage depressive symptoms such as self-help books or interactive websites, often with limited guidance and support from a health professional. Self-help groups were excluded.
The researchers found that patients with more severe depression at baseline derive "at least as good clinical benefit from 'low-intensity' interventions as less severely ill patients." They recommend including 'low-intensity' interventions in the first step of treating severely ill patients and encouraging the majority of patients to use them as the initial treatment option.http://www.sciencedaily.com/releases/20 ... 194010.htm
