Unmet need for recognition of common mental disorders in Australian general practice

Abstract

Objective: To determine the rate and predictors of unmet need for recognition of common mental disorders in Australian general practice. Design and setting: Cross‐sectional national audit of general practices throughout Australia in 1998–1999. Participants: 46515 ambulatory care patients attending 386 GPs. Screening tools: Prevalence of common mental disorders — 12 items from the 34‐item SPHERE self‐report questionnaire and associated classification system; prevalence of recognition of mental disorders by GPs — GPs reporting whether patients had depression, anxiety, mixed depression/anxiety, somatoform, or other psychological disorder; predictors of unmet need for recognition of mental disorders — self‐report questions about demography for patients and GPs, and about practice organisation for GPs. Main outcome measures: Reported recognition of psychological disorders by GPs; actual prevalence of disorders; and patient, GP and practice characteristics predicting the failure to recognise disorders. Results: GPs did not recognise mental disorder in 56% (11 922/21 210) of patients. These comprised 46% (5134/11 060) of patients in the higher level of mental disorders, and (in the second level of disorders) 58% (2906/5036) of patients with predominantly psychological symptoms, and 76% (3882/5114) of those with predominantly somatic symptoms. Patients more likely to have their need for psychological assessment met had the following characteristics: middle‐aged (odds ratio [OR], 1.76; 95% CI, 1.59–1.96), female (OR, 1.19; 95% CI, 1.12–1.27), Australian‐born (OR, 1.16; 95% CI, 1.08–1.24), unemployed (OR, 1.75; 95% CI, 1.64–1.89), single (OR, 1.52; 95% CI, 1.41–1.61), presenting with mainly psychological symptoms (OR, 3.54; 95% CI, 3.28–3.81), and presenting for psychological reasons (OR, 4.20; 95% CI, 3.02–5.82). Characteristics of doctors associated with meeting patients' need for assessment were being aged over 35 years (OR, 1.51; 95% CI, 1.09–2.08), having an interest in mental health (OR, 1.27; 95% CI, 1.15–1.41), having had previous mental health training (OR, 1.29; 95% CI, 1.15–1.45), being in part‐time practice (OR, 1.23; 95% CI, 1.09–1.39), seeing fewer than 100 patients per week (OR, 1.29; 95% CI, 1.13–1.47), working in practices with fewer than 2000 patients (OR, 1.28; 95% CI, 1.13–1.45) and working in regional centres (OR, 1.16; 95% CI, 1.05–1.28). Conclusion: Unmet need for recognition of common mental disorders remains high. Predictors of unmet need include a somatic symptom profile and practitioner and organisational characteristics which impede the provision of high quality mental health services.
