Objectives To assess the efficacy of haloperidol in reducing postoperative delirium in individuals undergoing thoracic surgery. Design Randomized double‐blind placebo‐controlled trial. Setting Surgical intensive care unit (ICU) of tertiary care center. Participants Individuals undergoing thoracic surgery (N=135). Intervention Low‐dose intravenous haloperidol (0.5 mg three times daily for a total of 11 doses) administered postoperatively. Measurements The primary outcome was delirium incidence during hospitalization. Secondary outcomes were time to delirium, delirium duration, delirium severity, and ICU and hospital length of stay. Delirium was assessed using the Confusion Assessment Method for the ICU and delirium severity using the Delirium Rating Scale‐Revised. Results Sixty‐eight participants were randomized to receive haloperidol and 67 placebo. No significant differences were observed between those receiving haloperidol and those receiving placebo in incident delirium (n=15 (22.1%) vs n=19 (28.4%); p = .43), time to delirium (p = .43), delirium duration (median 1 day, interquartile range (IQR) 1‐2 days vs median 1 day, IQR 1‐2 days; p = .71), delirium severity, ICU length of stay (median 2.2 days, IQR 1–3.3 days vs median 2.3 days, IQR 1‐4 days; p = .29), or hospital length of stay (median 10 days, IQR 8–11.5 days vs median 10 days, IQR 8‐12 days; p = .41). In the esophagectomy subgroup (n = 84), the haloperidol group was less likely to experience incident delirium (n=10 (23.8%) vs n=17 (40.5%); p = .16). There were no differences in time to delirium (p = .14), delirium duration (median 1 day, IQR 1‐2 days vs median 1 day, IQR 1‐2 days; p = .71), delirium severity, or hospital length of stay (median 11 days, IQR 10‐12 days vs median days 11, IQR 10‐15 days; p = .26). ICU length of stay was significantly shorter in the haloperidol group (median 2.8 days, IQR 1.1–3.8 days vs median 3.1 days, IQR 2.1–5.1 days; p = .03). Safety events were comparable between the groups. Conclusion Low‐dose postoperative haloperidol did not reduce delirium in individuals undergoing thoracic surgery but may be efficacious in those undergoing esophagectomy.

Background: Postoperative delirium affects up to 50% of patients undergoing esophagectomy and is associated with negative outcomes. The perioperative risk factors for delirium in this population are not well understood. We conducted this study to assess perioperative risk factors for postoperative delirium among esophagectomy patients. Methods:We performed a secondary data analysis of patients enrolled in a randomized controlled trial evaluating the efficacy of haloperidol prophylaxis postoperatively in reducing delirium among esophagectomy patients. Postoperative delirium was assessed twice daily using the Confusion Assessment Method for the ICU. Univariate and logistic regression analyses were performed to examine the association between perioperative variables and development of postoperative delirium. Results:Of 84 consecutive esophagectomy patients, 27 (32%) developed postoperative delirium. Patients who developed postoperative delirium had higher APACHE II scores [22.1 (6.5) versus 17.4 (6.8); p=0.003], longer mechanical ventilation days [1.7 (1.4) versus 1.0 (1.1); p=0.001], and longer ICU days [5.1 (2.6) versus 2.6 (1.6); p<0.001]. In a logistic regression model, only ICU length of stay was found to have significant association with postoperative delirium [OR 1.65; 95% CI 1.21-2.25].Conclusions: ICU length of stay was significantly associated with postoperative delirium. Other perioperative factors including duration of surgery, blood loss, and hemoglobin levels were not significantly associated with postoperative delirium.Abstract: 207 words

Objective: To compare differences in baseline depression and anxiety screenings between older injured patients with pre-existing diagnoses and those without. Background: Little is known about the prevalence and impact of psychiatric comorbidities on early postinjury depression and anxiety in nonneurologically injured older adults. Methods: This was a retrospective post-hoc analysis of data from the Trauma Medical Home, a multicenter randomized controlled trial (R01AG052493-01A1) that explored the effect of a collaborative care model on postinjury recovery for older adults compared to usual care. Results: Nearly half of the patients screened positive for at least mild depressive symptoms as measured by the Patient Health Questionnaire-9. Forty-one percent of the patients screened positive for at least mild anxiety symptoms as measured by the Generalized Anxiety Disorder Scale. Female patients with a history of concurrent anxiety and depression, greater injury severity scores, and higher Charlson scores were more likely to have mild anxiety at baseline assessment. Patients with a history of depression only, a prior history of depression and concurrent anxiety, and higher Charlson scores (greater medical comorbidity) had greater odds of at least mild depression at the time of hospital discharge after traumatic injury. Conclusions: Anxiety and depression are prevalent in the older adult trauma population, and affect women disproportionately. A dual diagnosis of depression and anxiety is particularly morbid. Mental illness must be considered and addressed with the same importance as other medical diagnoses in patients with injuries.
