Neighborhood Deprivation is Associated With Hospital Length of Stay, Discharge Disposition, and Readmission Rates for Patients Who Survive Hospitalization With Traumatic Brain Injury

Neighborhood Deprivation and Recovery Following Traumatic Brain Injury Among Older Adults

OBJECTIVE

Understanding the extent to which neighborhood impacts recovery following traumatic brain injury (TBI) among older adults could spur targeting of rehabilitation and other services to those living in more disadvantaged areas. The objective of the present study was to determine the extent to which neighborhood disadvantage influences recovery following TBI among older adults.

Setting and Participants: Community-dwelling Medicare beneficiaries aged ≥65 years hospitalized with TBI 2010-2018.

DESIGN AND MAIN MEASURES

In this retrospective cohort study, the Area Deprivation Index (ADI) was used to assess neighborhood deprivation by linking it to 9-digit beneficiary zip codes. We used national-level rankings to divide the cohort into the top 10% (highest neighborhood disadvantage), middle 11-90%, and bottom 10% (lowest neighborhood disadvantage). Recovery was operationalized as days at home, calculated by subtracting days spent in a care environment or deceased from monthly follow-up over the year post-TBI.

RESULTS

Among 13,747 Medicare beneficiaries with TBI, 1713 (12.7%) were in the lowest decile of ADI rankings and 1030 (7.6%) were in the highest decile of ADI rankings. Following covariate adjustment, beneficiaries in neighborhoods with greatest disadvantage [rate ratio (RtR) 0.96; 95% confidence interval (CI) 0.94, 0.98] and beneficiaries in middle ADI percentiles (RtR 0.98; 95% CI 0.97, 0.99) had fewer days at home per month compared to beneficiaries in neighborhoods with lowest disadvantage.

CONCLUSION

This study provides evidence that neighborhood is associated with recovery from TBI among older adults and highlights days at home as a recovery metric that is responsive to differences in neighborhood disadvantage.

Does Variation in Hospital Density and Social Deprivation Across Small Geographic Areas Play a Role in Perceived Barriers to Care Among People With Traumatic Brain Injury?

OBJECTIVE

To examine the role of area-level variables (hospital density and social deprivation) in the experience of health care access and quality among individuals with traumatic brain injury.

SETTING

Online questionnaire of community dwelling individuals Participants: 300 individuals with a history of traumatic brain injury with loss of consciousness.

DESIGN

Cross-sectional observational survey.

MAIN MEASURES

Barriers to Care Questionnaire, Social Deprivation Index, Hospital Density.

RESULTS

In an unadjusted regression model, less social deprivation and higher hospital density were associated with better perceived health care access and quality. After adjusting for personal factors of race, ethnicity, age, injury severity, food insecurity, and housing insecurity, the effect of social deprivation was fully attenuated whereas the effect of hospital density on health care access and quality remained significant. A model containing only the personal factors demonstrated reduced health care access and quality among individuals identifying as Hispanic. However, this effect was non-significant with the inclusion of the area-level contextual factors in a fully adjusted model.

CONCLUSIONS

Higher area-level hospital density is associated with a reduction in perceived barriers to care among individuals with TBI. In addition, contextual, area-level data accounted for the reduced health care access and quality among Hispanic participants. Area-level data can provide explanatory value in the study of health disparities for people with TBI from underrepresented racial and ethnic groups.

Mechanism of injury, resource utilisation and outcomes for patients admitted with head injuries under General Surgery

BACKGROUND

There has been a noticeable change in Irish hospitals in the demographics of patients sustaining head injuries that now includes many older patients suffering head injuries from low impact trauma.

AIMS

This study sought to define the demographic nature of patients admitted with head injuries over a 3-month period to Beaumont Hospital and to determine the mechanisms of head injuries sustained, resource utilisation during the inpatient admission and the outcomes for these patients.

METHODS

All head injuries admitted between December 1, 2023, and February 29, 2024, were captured and data pertaining to patient demographics, mechanism of injury, resource utilisation and outcomes were assessed. A comparison between patients under the age of 70 and over the age of 70 was also undertaken.

RESULTS

Thirty six patients were admitted in the 3-month period. 52.8% (n = 19) were over the age of 70. The mechanism of injury in the older cohort had a tendency to be low impact trauma, often with mechanical falls from standing height The median length of stay was 4.5 days. The older cohort was more likely to have a history of previous falls, to require input from allied health and social care professionals and were less likely to be discharged directly home.

CONCLUSIONS

Older patients requiring hospital admission for head injuries have significantly different care needs to younger patients admitted with head injuries. A national pathway for older patients who sustain head injuries needs to be implemented to ensure they get timely access to the investigations and specialists required.
