Acute inpatient treatment, hospitalization course and direct costs in bipolar patients with intellectual disability.
Expect longer psychiatric admissions and higher total costs when bipolar disorder co-occurs with ID—plan for extended stabilization and community-placement hurdles.
01Research in Context
What this study did
The team looked at every adult with bipolar disorder who entered a locked psychiatric ward in Taiwan during one year.
They split the group into two: 67 patients also had an intellectual disability, 1,073 did not.
Charts were compared for length of stay, total cost, medication dose, and how many were sent home on the first try.
What they found
The ID group stayed 30-40 % longer and the hospital bill was one-third higher.
Doctors gave them lower daily doses of mood drugs, yet more of them failed discharge and had to be readmitted later.
How this fits with other research
McQuaid et al. (2024) saw the same heavy load on inpatient units, but during COVID stays got shorter while kids with NDDs got sicker—opposite trend, same pressure.
Falcomata et al. (2012) explains why: most staff feel unprepared for dual diagnosis, so care slows down and safety checks multiply.
van der Geest et al. (2002) showed that mentoring teams to blend behavior plans with medicine cut readmissions; Chi-Shin’s long stays show the cost of not doing this.
Why it matters
When you write a discharge plan for a client with both bipolar and ID, budget extra days and add behavior-based step-down goals.
Ask the psychiatrist about teaming with a BCBA so medication and skills plans move together—this pairing once shaved a week off similar cases.

03Original abstract
To explore the impacts of intellectual disability (ID) on psychotropic medication use, length of hospital stay (LOS) and direct hospitalization costs during inpatient treatment for acute bipolar episodes, all 17,899 index hospitalizations due to acute bipolar episodes between 1998 and 2007 in Taiwan were identified from a total population health insurance claims database, amongst which 544 subjects had a concomitant diagnosis of ID. Pattern of psychotropic medication use, LOS, discharge outcome and direct costs during hospitalization were compared between bipolar patients with ID and without ID and multivariate models controlling for major cost confounders were used to explore the impacts of ID on LOS, discharge outcome and inpatient costs. The results indicated that, compared to bipolar patients without ID, bipolar patients with ID were younger, had longer LOS and received significantly lower daily equivalent dosages of antipsychotics, mood stabilizers, lithium and benzodiazepines. Significantly more bipolar patients with ID could not be discharged successfully. The longer LOS possibly reflected slower clinical stabilization, conservative use of medications and difficulty in community placement. The lower average daily reimbursements indicated that treatment of bipolar patients with ID were under-funded, whereas the higher total direct costs resulting from prolonged LOS placed greater economic straint on healthcare system. The findings support that bipolar patients with ID are clinically unique but relatively under-supported during acute hospitalization. Modifying current pharmacological intervention, health care resources allocation and community supporting structure is paramount to reducing LOS and improving hospitalization outcome.
