Background:
Most research has focused on recognition by GPs of the common mental disorders: depression and anxiety. However, less is known about the factors that determine whether patients with those disorders that are recognised receive any active treatment.
Aim:
To investigate factors associated with receiving active treatment among consecutive attenders identified by GPs as having a common mental disorder.
Setting:
Data were collected as part of a cluster randomised controlled trial in 30 general practices in the south of Bristol, UK, on the impact of mental health guidelines in primary care.
Method:
We studied 439 consecutive general practice attenders aged 16-64 years who were given a diagnosis of depression, anxiety, or chronic mixed anxiety and depression by their GP. The main outcome measure was the provision of any active treatment, whether pharmacological or psychological, for these disorders. Patient, GP, and practice level data, including sociodemographic, clinical, and administrative data were explored as predictors in a logistic regression model. Huber White variance estimates were used to account for hierarchical clustering.
Results:
Of those patients identified as having a common mental disorder by the GP, 54% were offered active treatment. Higher symptom score, as measured by the General Health Questionnaire (GHQ) (odds ratio [OR] = 1.09; 95% confidence interval [CI] = 1.06 to 1.13; P<0.001) and being male (OR = 1.54; 95% CI = 1.13 to 2.09; P = 0.006), were both associated with an increased likelihood of being offered active treatment. Patients with anxiety (OR = 0.24; 95% = CI 0.14 to 0.41; P<0.001), or chronic mixed anxiety/depression (OR = 0.41; 95% CI = 0.23 to 0.73; P = 0.003) were less likely to be offered active treatment than those considered to have depression.
Conclusion:
When deciding to offer active treatment for common mental disorders, GPs appear to be influenced by the severity of symptoms rather than their 'understandability' in relation to recent life stresses or the social context of distress. Further research is needed to investigate why men are more likely and those with an anxiety disorder less likely, to be offered active treatment.
