PRIMARY outcome

Timeframe: From hospital admission until the date of first documented delirium, assessed up to 28 days post-transplant

Population: Only 20 bright light therapy and 18 sham light participants were analyzed because 2 participants (one from each arm) only had one assessment. Consequently, no change could be documented to analyze change of delirium scales. They did not drop out; they just completed their transplant before more data could be gathered.

Monday, Wednesday, and Friday assessments will begin after beginning light therapy and include the Delirium Rating Scale-Revised-98 (DRS-98)and Memorial Delirium Assessment Scale (MDAS)

0 Participants

SECONDARY outcome

Timeframe: From first documented episode of delirium until discharge from the hospital, assessed up to 28 days post-transplant

Population: Only one case of delirium developed, and only an MDAS score was collected for this participant.

Monday, Wednesday, and Friday assessments of the Memorial Delirium Assessment Scale (MDAS); Patients will receive assessments after beginning light therapy until day 28 post-transplant or discharge, whichever comes first. 10 item scale Items are rated on a four-point scale from 0 (none) to 3 (severe) depending on the level of impairment, rendering a maximum possible score of 30. A score of 13 has been recommended as a cut-off for establishing the diagnosis of delirium

SECONDARY outcome

Timeframe: From admission to hospital to discharge, an expected average of 28 days post-transplant

Population: Only one case of delirium developed, and we did not collect data on antipsychotic medication use for this one participant.

SECONDARY outcome

Timeframe: From admission to hospital to discharge, an expected average of 28 days post-transplant

Population: One participant in the sham light arm was missing date of discharge, so only 18 hospital lengths of stay were able to be calculated in that arm.
