Abstract
Background: Reorientation programmes have been an important component of neurotrauma reha-
bilitation for adults who suffer from post-traumatic amnesia (PTA) after traumatic brain injury (TBI);
however, research testing the efficacy of acute programmes is limited.
Objective: This study aimed to determine if it is feasible to provide a standardized environmental
reorientation programme to adults suffering from PTA after TBI in an acute care hospital setting,
and whether it is likely to be beneficial.
Methods: We conducted a randomized controlled trial with concealed allocation and intention-to-
treat analysis. A total of 40 participants suffering from PTA after TBI were included. The control
group received usual care; the experimental group received usual care plus a standardized ori-
entation programme inclusive of environmental cues. The primary outcome measure was time
to emergence from PTA measured by the Westmead PTA Scale, assessed daily from hospital
admission or on regaining consciousness.
Results: Adherence to the orientation programme was high, and there were no study-related
adverse responses to the environmental orientation programme. Although there were no statis-
tically significant between-group differences in time to emergence, the median time to emergence
was shorter for those who received the standardized reorientation programme (9.0 (6.4–11.6) versus
13.0 (4.5–21.5) days). Multivariate analysis showed that the Glasgow Coma Scale (GCS) at scene
(P = 0.041) and GCS at arrival at hospital (P = 0.0001) were significant factors contributing to the
longer length of PTA.
Conclusion: Providing an orientation programme in acute care is feasible for adults suffering from
PTA after TBI. A future efficacy trial would require 216 participants to detect a between-group
difference of 5 days with an alpha of 0.05 and a power of 80%.
