2.5. Analysis
To identify the characteristics of the nursing homes that
had a high proportion of deaths within the facility, we standardized
by dividing the annual number of deaths within
the nursing home by the number of beds. We dichotomized
the facility characteristics, except for the policy on EOL
which was divided into three, and used Mann–Whitney’s
test. To compare the characteristics of the residents who
died in the nursing home with those who died in hospitals,
the unadjusted Odd’s ratio was calculated.
Next, the statistically significant facility and resident
variables were inputted into a multivariate, step-wise
logistic regression analysis to calculate the adjusted Odd’s
ratio for dying in the nursing home. Except for age and
length of stay, which were treated as continuous variables,
items were collapsed into dichotomous variables.
To analyze the preferences of the resident or the family
and whether they had been adhered, we divided our sample
into those who had died in nursing homes, and those
who had died in hospitals. We then used Chi-square test
to calculate the statistical significance between the two
groups for the LST procedures they had received, for the
LST that they had received despite their preference not to,and for the LST they did not receive despite their preference
to receive them. We excluded those residents whose
preferences were not known.
All analyses were conducted using SPSS (version 17.0).
The level of significance was set at p < 0.05.
