One nit: The article switches back and forth between incorrect schizophrenia diagnosis (11% of residents) and prescription antipsychotics (21% of residents), but those should be treated as separate topics. Antipsychotics can be beneficial in many conditions beyond schizophrenia, such as insomnia (at low doses), bipolar disorder, or depression (to boost efficacy of primary antidepressant treatments). The "antipsychotic" label is an unfortunate holdover from long ago, but the drugs are actually much more useful than they sound. Current generation antipsychotics also have significantly fewer risks than first-generation antipsychotics. The article's attempt to call them "chemical straightjackets" is a cheap shot at a class of medications that can be very beneficial for several conditions. Overprescription is a problem, but that doesn't mean all prescriptions are bad.
The truly alarming stat is buried deeper in the article: The fact that 1 in 9 nursing home residents is diagnosed with schizophrenia is way too high. Schizophrenic patients will be overrepresented in nursing homes because they are less able to care for themselves in old age, but that's still an unbelievably high number. These misdiagnoses are what we should be focused on.
