PURPOSE: The
purpose of the study is to identify various factors that affect the change in
pre- and post-operative health self-assessments (Health Change) of
ostomates. METHODOLOGY: This retrospective study uses a subset of data
from the 125-question Ostomy Comprehensive Health and Life Assessment survey (n
= 545). Data taken from the ongoing, nationally distributed survey
include ostomates with single colostomy or ileostomy stomas less than three
years post-operative at time of survey. Life Effect is derived from
self-assessments of pre- and post-operative health. Data were analyzed
using chi-square and exact tests of association, odds ratios and
Mantel-Haenszel statistics. RESULTS: Factors found to have an
association with Health Change were age at surgery, (p < .01) and
whether surgery was expected (p < .01). Positive Health Change
was more likely for ostomates who expected surgery (Odds Ratio = 4.23)
and were 50 years of age or younger at the time of surgery (Odds Ratio =
3.54). The diagnosis leading to surgery was found to interact with type
of stoma in its effect on Health Change. For colostomates, no association
between diagnosis leading to surgery and Health Change was found, while
ileostomates treated for gastrointestinal disease reported a positive Health
Change more frequently than those treated for cancer. CONCLUSIONS:
The data suggest that ostomates who are younger and expect to have surgery are
more likely to report a positive change between pre- and post- health
self-assessments. Among ileostomates, those treated for gastrointestinal
disease were more likely to report a positive change between pre- and
post-operative health self-assessments than those treated for cancer.
