Bipolar disorder associated with high absence-related costs
Lost time, absence costs, and reduced productivity output for employees with bipolar disorder. Kleinman NL, Brook RA, Rajagopalan K, Gardner HH, Brizee TJ, Smeeding JE. J Occup Environ Med. 2005. 47: 1117-1124.
Aim
To analyze the impact of bipolar disorder (BPD, often referred to as manic depression) on lost work time (absenteeism) and at-work productivity.
Looked at
230,000 employees from a large US-based insurance claims database.
How?
Diagnosis and treatment data, and health-related absence and real productivity information from employees with BPD were compared with those from employees without BPD.
Results
-
Over the period of a year, employees with BPD had significantly lower work productivity than the other groups, a 20-22% productivity decrement.

What does this mean?
A diagnosis of BPD is strongly associated with raised costs for absenteeism and resulting loss of productivity.
