Two articles in this month's issue focus on nursing homes. Legislation enacted in 1987 mandated provision of necessary mental health services to residents, although research in the 1990s found poor compliance. In this month's lead article, Yue Li, Ph.D., presents findings of an analysis of data from four National Nursing Home Surveys—1995, 1997, 1999, and 2004 (the most recent survey)—that identified which of three models of on-site service delivery was used by the surveyed facilities: provision on a regular basis, on an on-call basis, and on both a regular and an on-call basis. About 80% of facilities provided on-site mental health services each survey year. In 2004 services were provided regularly in 25%, on an on-call basis in 24%, and on both a regular and an on-call basis in 28%. The remaining 22% of nursing homes provided no on-site mental health services (page 349). The second study, by Sonne P. Lemke, Ph.D., and Jeanne A. Schaefer, Ph.D., R.N., looked at changes in the prevalence of psychiatric disorders from the 1990s to 2006 among residents of the approximately 130 facilities operated by the Department of Veterans Affairs. First, the authors used data from admission and census samples to document overall changes. However, more detailed analyses by birth cohort and age group revealed interesting trends that might have been overlooked ottherwise. The authors encourage use of their approach to provide policy makers and planners with a better understanding of the complexity of changing prevalence patterns (page 356). In Taking Issue, Martha Sajatovic, M.D., cites several reasons for inadequate mental health service provision in nursing homes and calls for collaboration among policy makers, insurers, and health care professionals to head off a major problem (page 335).
