We estimated the cumulative incidence of suicide among adults aged 65 years and older in nursing homes by abstracting resident census data published in the Nursing Home Compendium, which reported that 85.3% of nursing home residents in Virginia were aged 65 years or older.We estimated the range for the annual incidence of suicide among adults aged 65 years and older in nursing homes with this resident census data under scenarios that 80%, 85% and 90% of the resident population were in this age group from 2006 to 2011. We compared this to cumulative incidence of suicide in the community among the population aged 65 years and older in 2010 in data from the US Census.Finally, although we did not use this variable in our main analysis, we calculated the sensitivity and specificity of the VVDRS indicator for supervised residential facility as an identifier of decedents in LTC.
