We examined the charts of 911 nursing home patients in Hennepin County, Minnesota, to determine the prevalence of written do-not-resuscitate (DNR) orders. Information regarding demographic characteristics, and whether a surrogate decisionmaker was available and participated in the decision, was also collected. Twenty-seven percent of patients had DNR orders. ⋯ Univariate analysis identified female sex; increased age, level of care (skilled versus intermediate), presence of a potential surrogate decisionmaker, and increasing length of time since nursing home admission as factors associated with presence of DNR orders. When a logistic regression model was used, increased age, increased length of time since nursing home admission, skilled versus intermediate level of care, and presence of a surrogate decisionmaker were independently associated with presence of DNR status. Several variables are independently associated with written DNR orders; their relationship to the factors physicians use in decision making requires further study.

Height is an essential variable when assessing renal clearance, nutritional status, and absorption. Standard methods of estimating height are impractical in the nonambulant. One hundred sixty-five elderly inpatients were studied. ⋯ Total arm, upper arm, and forearm measurements were obtained in both erect and supine positions. Measured height correlated best with supine total arm length (R2 = .69), knee-to-floor height (R2 = .63), and erect forearm length (R2 = .61). A nomogram relating both supine total arm length and knee-to-floor height with the patient's measured height has been prepared.
