Insights
Childhood maltreatment (CM) significantly increases the risk of post-traumatic stress disorder (PTSD). This study found substantial excess costs for healthcare and absenteeism in Germany, with absenteeism comprising about half of the total burden.
Area of Science:
- Public Health
- Health Economics
- Psychiatry
Background:
- Childhood maltreatment (CM) is a significant risk factor for post-traumatic stress disorder (PTSD).
- PTSD prevalence in Europe is higher than previously estimated.
- The economic burden of PTSD is substantial, but costs specific to PTSD with CM in Germany are under-researched.
Purpose of the Study:
- To determine the excess healthcare and absenteeism costs associated with PTSD in individuals with a history of childhood maltreatment (PTSD-CM) in Germany.
- To compare these costs to individuals without PTSD.
Main Methods:
- Utilized baseline data from a multi-center randomized controlled trial for individuals with PTSD-CM (n=361) and data from individuals without PTSD (n=4760).
- Employed entropy balancing to ensure sociodemographic comparability between groups.
- Calculated six-month excess costs from a societal perspective in 2022 using two-part models.
Main Results:
- The total six-month excess costs for PTSD-CM were €8864 per person.
- Excess healthcare costs were €4647 and excess absenteeism costs were €4217 per person.
- Individuals with severe to extreme PTSD symptoms incurred higher excess costs (€11,433) compared to those with mild to moderate symptoms (€6038).
Conclusions:
- Excess healthcare and absenteeism costs linked to PTSD-CM are substantial in Germany.
- Absenteeism represents approximately half of the total excess costs associated with PTSD-CM.
- These findings highlight the significant economic impact of childhood maltreatment on individuals with PTSD.
Background:
Childhood maltreatment (CM) significantly increases the risk of developing post-traumatic stress disorder (PTSD) for which the prevalence in Europe is higher than initially assumed. While the high economic burden of PTSD is well-documented, little is known about the health care cost differences between individuals with PTSD-CM and those without PTSD in Germany. This study aimed to determine the excess health care and absenteeism costs associated with PTSD-CM in Germany.
Methods:
Baseline data from a multi-center randomized controlled trial on individuals with PTSD-CM (n = 361) were combined with data from individuals without PTSD (n = 4760). Entropy balancing was used to balance the data sets with regard to sociodemographic characteristics. Six-month excess health care costs from a societal perspective were calculated for 2022, using two-part models with logit specification for the first part and a generalized linear model for the second part.
Results:
The total six-month excess costs associated with PTSD-CM were €8864 (95% CI: €6855 to €10,873) per person. Of this, the excess health care costs accounted for €4647 (95% CI €3296 to €5997) and the excess costs of absenteeism for €4217 (95% CI: €3121 to €5314). Individuals with mild to moderate PTSD symptoms incurred total excess costs of €6038 (95% CI: €3879 to €8197), while those with severe to extreme symptoms faced €11,433 (95% CI: €8220 to €14,646).
Conclusions:
Excess health care and absenteeism costs associated with PTSD-CM were substantial, with absenteeism accounting for roughly half of the total excess costs.
