Depression IssuesDepression Issues

• Depression exists on a continuum• Major depression is quite common

• Lifetime prevalence rates range from 5.2% to 17.1%• Women are twice as likely to develop depression as are men• Higher rates in young adults and among individuals in lower

socioeconomic groups. • Depression prevalence varies across cultures

• Prevalence of depression has been increasing over the last 50 years

20% of those with major depression have symptoms that

persist beyond 2 years

Depression In Primary Care

• Prevalence of depression in Medically ill patients is twice that of General populations

• Medical Disease is a risk factor itself for Depression

• Rates of Depression increases with Acuity of care from low 9% in general population to 30% in acutely hospitalized patients

‘Presenteeism’ is a greater problem than absenteeism

Absenteeism• Time spent away from the job due to illness

Presenteeism• Impaired job performance and productivity while at work

Depression has huge impact on workplace productivity

What are the clinical milestones for treatment of depression?

• Onset of response (≥20% improvement from baseline) • Response (≥50% improvement from baseline)• Different grades of remission:

Is remission the optimal outcome?

• Remission (as measured by symptom scales) is an important target for treatment

• Residual symptoms are predictors of relapse, chronicity and suicidality

• There are various remission criteria

• But, does remission = ‘health’ or functional recovery?

‘Health’ is a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity.

Many depressed patients are still depressed.

Depressed patients continue to have needs that are not being fully addressed1

• Depressed patients present with emotional and physical symptoms.

• Approximately 30% of depressed patients achieve remission in clinical trials2*

• Up to 70% of patients who respond fail to remit2*

• Incomplete relief from symptoms may increase the risk of relapse2,3

• Emotional and physical symptoms may delay achieving remission.

*In antidepressant clinical drug trials.

What is a ‘good enough’ outcome for the treatment of depression?

Physician perspective: Signs Adverse events

Patient perspective: Symptoms Adverse events Wellbeing Quality of life Functioning Economic aspects

Society perspective: Functioning Economic aspects

34

Factors identified by depressed outpatients as very important in defining remission

In rank order: Presence of positive mental health

(e.g. optimism, self-confidence) Feeling like your usual, normal self Return to usual level of functioning at work, home

or school Feeling in emotional control Participating in, and enjoying, relationships with

family and friends Absence of symptoms of depression

Zimmerman et al. Am J Psychiatry 2006: 163 (1): 148–150

35

Sick leave – the patient’s perspective

Potential benefits Removal from occupational stresses and under-performing More time and opportunity to engage in activities conducive to

recovery

Drawbacks Patient inactivity, retreats to bed Isolation, without the usual social contacts afforded by the

workplace Development of a secondary anxiety pattern whereby patient

becomes more apprehensive about returning to work The longer the disability leave, the less likely it is that the patient

will ever return to gainful employment

Bilsker et al. Can J Psychiatry 2006; 51 (2): 76–83

Impact of depression on sick leave duration

• Choose appropriate treatments

• Enhance adherence

• Monitor outcomes

• Manage non-responders

Take Home Message

• ‘Symptom free’ is a realistic remission outcome, however success rates differ among antidepressants

• Recovery of functionality – especially work functioning – is important to patients (and should be for clinicians)

• Remission of symptoms is not always associated with functional improvement

• Escitalopram superiorly improves daily living and functional outcomes compared to other SSRIs & SNRIs.
