The objective of this study was to evaluate the accuracy of the social work
er estimation (SWE) of the length of survival of patients who were seen at
the end stage of their terminal illness, in home-based palliative care trea
tment. Estimates were filled out on a form every 2 weeks during the time of
the visits until the patient's discharge or death. The wording used by the
social worker was the 'average survival period'. Survival was measured fro
m the time of each survival prognostication until death from any cause. Bot
h SWE and actual survival were categorized into less than or equal to4, 5-8
, 9-12 and > 12 weeks. Then, 29 estimates were analyzed using the SPSS stat
istical software package. The mean and median actual survivals of the total
cohort were 6.5 and 5.1 weeks, respectively. The minimum and maximum weeks
of actual survival were 0.1 and 23.1, respectively. The mean and median di
fferences between SWE and actual survival were 2.1 and 1.6 weeks, respectiv
ely (range: 18.7, minimum and maximum differences of -7.3 and 11.4 weeks, r
espectively). The Pearson correlation coefficient between actual survival a
nd SWE was 0.827 (P < 0.001). Overall, 59% (17/29) were correctly assigned
by social worker to the correct survival categories. Our study suggests tha
t the oncology social worker can be a valuable resource for information abo
ut the patient's prognosis of life span. (C) 2001 Elsevier Science Ireland
