A selective placement strategy for surgical feeding tubes benefits trauma patients

Defining the Mortality Rate of Elderly Trauma Patients With Operative Feeding Tubes

INTRODUCTION

Placement of feeding tubes in elderly patients has not been studied in elderly trauma patients. The objectives of this study were to determine in-hospital mortality in elderly trauma patients receiving operative feeding tubes and to identify factors associated with in-hospital mortality.

METHODS

A retrospective study utilizing 2017 National Trauma Data Bank data was conducted. Trauma patients aged 65 and older with operative feeding tubes were included. Demographic, injury, comorbidity, and general hospital course data were analyzed. Two cohorts were constructed: survival and non-survival to hospital discharge. Bivariate analysis and logistic regression were performed to determine factors independently associated with in-hospital mortality.

RESULTS

A total of 3,398 patients were analyzed with 331 (9.7%) dying during hospitalization. Patients had a median age of 75 years and sustained severe injuries (median ISS 17). Patients who died were older (76 vs. 75 years, p = .03), more severely injured (ISS 22 vs. 17, p < .001), had a higher geriatric trauma outcome score (134 vs. 121, p < .001), and had lower rates of dementia (8 vs. 13%, p = .01). Multivariate regression showed male sex, lower admission GCS, higher Charlson Comorbidity Index, and an Advance Directive Limiting Care (ADLC) were independently associated with in-hospital mortality. Dementia diagnosis was negatively associated with in-hospital mortality.

CONCLUSIONS

The in-hospital mortality rate for elderly trauma patients with operative feeding tubes placed was notably high. Identifying factors associated with in-hospital mortality will serve to assist providers in counseling patients and caregivers about the outcomes of operative feeding tube placement in this patient population.
