Trends in the use of psychotropic drugs in people with intellectual disability in Taiwan: a nationwide outpatient service study, 1997-2007.

Hsu et al. (2014) tracked every outpatient prescription for people with intellectual disability in Taiwan. They used the national health insurance claims from 1997 through 2007.

The team counted how many people filled psychotropic medicines each year. They looked at antipsychotics, sleeping pills, antidepressants, and mood drugs.

Psychotropic use rose from 17.8% to 23.2% in ten years. The biggest jumps were in antipsychotics and sleeping pills.

More doctors wrote these scripts outside of hospitals. The climb hints at wider off-label use for behavior or sleep issues.

Yen et al. (2009) saw a similar rate in Taiwanese teens with ID: 23.8% used daily meds. Their snapshot lines up with the 2007 end point, so the trend looks real.

de Kuijper et al. (2010) found 32% of Dutch residents with ID took antipsychotics, mostly for challenging behavior, not psychosis. The Dutch numbers are higher, but both studies flag the same red light: behavior drives the script.

Boswell et al. (2023) in Finland saw 83% of adults with ID fill any medicine and antipsychotic use was 12× the norm. The Finnish rate tops Taiwan’s, yet both countries show the same upward pull toward heavy psychotropic load.

If you serve adults or teens with ID, check your own caseload. Count who is on antipsychotics or sleeping pills and ask why. Pair medication reviews with functional behavior assessments. Push for sleep-hygiene or skill-building plans before reflex scripts. Your watch can curb silent polypharmacy growth.
