Purpose
There is increasing pressure on mental health providers to reduce the duration of treatments, while retaining level of quality and effectiveness. The risk is that the population is underserved and therefore needs new treatment episodes. The primary aim of this study was to investigate whether duration of treatment and return into mental health care were related.
Methods
This study examined Dutch patients with an initial treatment episode in 2009 or 2010 in specialized mental health settings for depressive disorder (N = 85,754). Follow-up data about treatment episodes were available up until 2013. The data set included demographic (age, gender), and clinical factors (comorbidity with other DSM-IV Axis; scores on the ‘Global Assessment of Functioning’). Cox regression analyses were used to assess whether duration of treatment and relapse into mental health care were related.
Results
The majority of patients did not return into mental health care (86 %). Patients with a shorter duration of treatment (5–250 min; 251–500 min and 751–1000 min) were slightly more likely to return (reference group: >1000 min) (HR 1.19 95 % CI 1.13–1.26; HR 1.11 95 % CI 1.06–1.17; HR 1.18 95 % CI 1.11–1.25), adjusted for demographic and clinical variables.
Conclusions
The results suggest that a longer duration of treatment may prevent return into mental health care in some groups. However, because of the design of the study, no causal inference can be drawn. Further research, preferably in a RCT, is needed to determine whether the trend towards lower intensity treatments is associated with repeated mental health care use.
