Background: Do-not-resuscitate (DNR) orders for critically ill patient
s are frequently miscommunicated between attending physicians, house s
taff, and nurses. A computer-based system was developed to improve the
communication of a procedure-specific DNR order form. Methods: Concor
dance of understanding of patients' DNR status was measured with the u
se of unstructured DNR orders (period 1), procedure-specific DNR order
forms (period 2), and procedure-specific DNR order forms administered
with a computer-based communication system (period 3). The 3 componen
ts of the DNR order assessed were (1) the clinical events to which the
DNR order applied, (2) whether the DNR order withheld all elements of
cardiopulmonary resuscitation, and (3) whether other treatments were
to be withheld. Results: For the 147 patients, the computer-based syst
em in period 3 (n = 71) improved concordance for attending physicians
and nurses or residents for all 3 of the DNR components compared with
period 1 (n = 40) and some of the DNR components compared with period
2 (n = 36). Concordance was ''substantial'' or ''almost perfect'' as m
easured by the kappa statistic during period 3. The proportion of agre
ement for the composite of all 3 components of the DNR order increased
during each period (P<.001, period 3 vs period 1). Overall agreement
be between all caregivers for the composite DNR order also improved fr
om period 1 (22.2%) to period 2 (47.8%) and period 3 (61.9%; P<.001 vs
period 1). Errors in order entry were detected by physicians because
of the computer system and corrected in 9.9% of DNR orders in period 3
. Progress note documentation of DNR status did not improve during per
iod 3. The procedures of period 3 were considered acceptable by the ph
ysician and nursing staff. Conclusion: A computer-based system combine
d with a procedure-specific DNR order form improves communication of p
atients' DNR status in a critical care setting.
