Guidelines for preventive activities in general practice 9th edition

10.1 Depression

Age 0-9 10-14 15-19 20-24 25-29 30-34 35-39 40-44 45-49 50-54 55-59 60-64 65-69 70-79+

While there is evidence that depression screening instruments have reasonable sensitivity and specificity, the evidence for improved health outcomes and cost-effectiveness of screening for depression in primary care remains unclear. There is evidence for routine screening for depression in the general adult population in the context of staff-assisted support to the GP in providing depression care, case management and coordination (eg via practice nurses; B).31 There is insufficient evidence to recommend routine screening in adults or adolescents where case management and coordination is not available (C).31 There is insufficient evidence to recommend screening in children.32 Clinicians should maintain a high level of awareness for depressive symptoms in patients at high risk of depression and make appropriate clinical assessments wherever the risk is high.33

Table 10.1.1. Depression: Identifying risk
Who is at risk?What should be done?How often?
Average risk
Adult population aged ≥18 years, where no risk factors for depression are identified 31 Be alert to possible depression, but do not routinely screen unless staff-assisted depression care supports are in place (C) Opportunistically
Increased risk
  • Past history of depression31
  • Family history of depression 33
  • Other psychiatric disorders, including substance misuse 34
  • Chronic medical conditions
  • Unemployment 35
  • Low socioeconomic status (SES)
  • Older adults with significant life events (eg illness, cognitive decline, bereavement or institutional placement) 36
  • All family members who have experienced family violence
  • Lesbian, gay and bisexual peoples
  • Experience of child abuse
Recurrent screening may be more useful in people deemed to be at higher risk of depression (B); however, in the case of people with chronic diseases (eg diabetes, heart failure, coronary heart disease), a screen-and-treat strategy for depression has not been shown to improve chronic disease symptoms nor reduce health service use

Maintain a high level of clinical awareness of those at high risk of depression and consider depression when a person presents with suggestive symptoms such as low mood, insomnia, anhedonia, suicidal thoughts
Pregnant and postpartum women 31

Risk factors for depression during pregnancy and postpartum include poor self-esteem, child care stress, prenatal anxiety, life stress, decreased social support, single/unpartnered relationship status, history of depression, difficult infant temperament, previous postpartum depression, lower SES, and unintended pregnancy
Recurrent screening may be more useful in people deemed to be at higher risk of depression (B) 31 Opportunistically
Adolescents aged 12–18 years, particularly with32, 37–39:
  • family history of depression
  • deliberate self-harm
  • comorbid mental health or chronic medical conditions
  • experience of a major negative life event (including being bullied)
The benefits of screening alone have not been established, but screening is recommended where access to effective treatment and follow up is available

Be alert for signs of depression in this age group (B)40, 41

Consider use of HE2ADS3 assessment tool (refer to Practice Point m in Table 3.2)
At every encounter
SES, socioeconomic status
Table 10.1.2. Test to detect depression
Question regarding mood and anhedonia Asking two simple questions may be as effective as longer instruments42:
  • ‘Over the past two weeks, have you felt down, depressed or hopeless?’
  • ‘Over the past two weeks, have you felt little interest or pleasure in doing things?’
Asking a patient if help is needed in addition to these two screening questions improves the specificity of a GP diagnosis of depression (IV) 33

In adolescents, consider use of HE2ADS3 assessment tool (refer to Chapter 3. Preventive activities in children and young people) 43

In women in the perinatal period, the Edinburgh Postnatal Depression Scale (EPDS) can be used to detect women requiring further assessment of possible major depression (B in the postnatal period) at Black Dog Institute or Beyond Blue

Refer to Section 10.3. Identification of intimate partner violence, as depression is a common reason for presentation in those experiencing violence
