The relationship between elderly suicide rates, population density and room density.

The data in this letter provide some insights into the complex needs of older adult psychiatric patients. If this sample is representative of a typical older adult population, then other services providing psychiatric care for older adults with similarly high levels of aggressive and challenging behavior may consider adopting a similar model in the safe practice of physical interventions. As this letter reveals, failure to do so may increase the probability of the application of standard physical intervention techniques causing pain and/or injury. Clearly this is something all mental healthcare staff should seek to avoid.
