ABSTRACT

OBJECTIVE: To determine whether severity of head and extracranial injuries (ECI) is associated with suicidal ideation (SI) or suicide attempt (SA) after traumatic brain injury (TBI). DESIGN: Factors associated with SI and SA were assessed in this inception cohort study using data collected 1, 2, and 5 years post-TBI from the National Trauma Data Bank and Traumatic Brain Injury Model Systems (TBIMS) databases. SETTING: Level I trauma centers, inpatient rehabilitation centers, and the community. PARTICIPANTS: Participants with TBI from 15 TBIMS Centers with linked National Trauma Data Bank trauma data (N=3575). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: SI was measured via the Patient Health Questionnaire 9 (question 9). SA in the last year was assessed via interview. ECI was measured by the Injury Severity Scale (nonhead) and categorized as none, mild, moderate, or severe. RESULTS: There were 293 (8.2%) participants who had SI without SA and 109 (3.0%) who had SA at least once in the first 5 years postinjury. Random effects logit modeling showed a higher likelihood of SI when ECI was severe (odds ratio=2.73; 95% confidence interval, 1.55-4.82; P=.001). Drug use at time of injury was also associated with SI (odds ratio=1.69; 95% confidence interval, 1.11-2.86; P=.015). Severity of ECI was not associated with SA. CONCLUSIONS: Severe ECI carried a nearly 3-fold increase in the odds of SI after TBI, but it was not related to SA. Head injury severity and less severe ECI were not associated with SI or SA. These findings warrant additional work to identify factors associated with severe ECI that make individuals more susceptible to SI after TBI.

ABSTRACT

OBJECTIVE: Authors sought to use a cognitive assessment instrument validated for assessing low-functioning patients to broaden knowledge about the rate and correlates of functional decline. METHODS: Patients were examined across a wide range of baseline cognitive and functional status, and changes in cognitive and functional status were examined. A group of 424 elderly patients with schizophrenia were followed up over a 6-year period; 280 of these manifested severe cognitive impairment at baseline. Patients were examined with an instrument designed for cognitive and functional assessment of severe cognitive impairment: the Alzheimer's Disease Assessment Scale-Late (ADAS-L). RESULTS: Patients with higher and lower baseline scores manifested equivalent declines in the ADAS-L cognitive subscale, but differences in decline on basic activities of daily living. Random-effects regression analysis indicated that functional changes were significantly correlated with cognitive changes for the sample as whole and that cognitive changes were the best predictor of changes in functional status over time. Baseline cognitive status was not a statistically significant covariate for functional change, nor was the course of negative symptoms over the follow-up period. CONCLUSIONS: Cognitive change appears very similar in magnitude across older, poor-outcome patients with different baselines of cognitive impairment. In contrast, functional decline was limited to patients with lower levels of functioning at baseline. These findings suggest that cognitive thresholds for impairments in different aspects of functional status may exist in patients with schizophrenia. Basic activities of daily living decline only in patients with very low levels of baseline cognitive functioning.
