Patients with Major Depressive Disorders (MDD)
Even among patients with MDD who do respond to a first treatment, as many as two thirds do not recover fully, and continue to experience residual symptoms.1,2
What’s more, the proportion of MDD patients who achieve remission decreases significantly after each treatment failure, from 31% with a second treatment, to 14% with a third and 13% with a fourth.*2
MDD: A Global illness
Depression, or MDD, affects approximately 40.3 million people across Europe, causing substantial disability.3
Between the years 2005 and 2015, the number of people living with depression increased by almost a fifth (18.4%)3 and it now represents the leading cause of disability worldwide.4,5
This disability causes a wide range of physical, emotional and cognitive symptoms, including:6,7
Loss of pleasure in all/almost all activities
Fatigue and sleep disruption
Difficulties with thinking, concentrating or making decisions
The management of MDD is in urgent need of reform; at its worst it can be fatal, with
patients at a 20-fold higher risk of suicide than the general population.8
In 2004, depression cost
In addition to its effect on patients’ quality of life,11,12 MDD has a significant socio-economic impact on Europe, with the highest number of days absent for any physical or mental disorder.13 This contributes to the substantial costs associated with the condition: in 2004, depression cost Europe approximately €118 billion – roughly 1% of the total economy of Europe.10
The current treatment paradigm
Achieving response and remission in MDD requires patients to wait weeks and even months.14,15
The impact of lengthy and ineffective treatment
Lengthy and ineffective treatments can prolong patient suffering, reduce expectations
and reinforce negative emotions such as hopelessness.12
A number of factors contribute to this, including:
With MDD patients already at a 20-fold greater risk of suicide than the general population,**8 a delay in finding an effective treatment may prove
Earlier recognition of inadequate treatment response
Remission rates for patients can be as low as 14% and 13% on their third and fourth antidepressant therapies respectively.*2
Helping Patients to step out of MDD
Despite the low levels of remission that patients are currently experiencing after their third and fourth treatments,2 the need to continue to fight and achieve remission is as pressing as ever: acting with urgency to optimise treatment may reduce patient suffering, increase the likelihood of both asymptomatic remission and functional recovery.16-19
Steps urgently need to be taken to help make achieving this remission a reality, including:
Early recognition of inadequate response to treatment, which could offer patients the opportunity to achieve improved response and remission rates as soon as possible16,20
Early treatment switch if there is an inadequate response to treatment, which could give patients the opportunity to achieve a meaningful response, and potentially remission, sooner16
Early identification of patients needing specialised care, which may reduce the number of treatment steps needed to achieve response, and ultimately benefit their quality of life21
* From a report comparing acute and longer-term treatment outcomes associated with each of four successive steps in the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) trial. Remission was defined as a score of ≤5 on the Quick Inventory of Depressive Symptomatology–Self-Report (QIDS-SR16) (equivalent to ≤7 on the 17-item Hamilton Rating Scale for Depression [HRSD17]).2
** Determined by application of Bayes’s Rule, which states that the probability of suicide is equal to the probability of suicide given death (proportionate mortality prevalence) times the probability of death (general mortality prevalence).
