Decreasing Trauma Readmission Rates by Implementing a Callback Program

Transitional care programs for trauma patients: A scoping review

BACKGROUND

Transitional care programs establish comprehensive outpatient care after hospitalization. This scoping review aimed to define participant characteristics and structure of transitional care programs for injured adults as well as associated readmission rates, cost of care, and follow-up adherence.

METHODS

We conducted a scoping review in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews standard. Information sources searched were Medline, the Cochrane Library, CINAHL, and Scopus Plus with Full Text. Eligibility criteria were systematic reviews, clinical trials, and observational studies of transitional care programs for injured adults in the United States, published in English since 2000. Two independent reviewers screened all full texts. A data charting process extracted patient characteristics, program structure, readmission rates, cost of care, and follow-up adherence for each study.

RESULTS

A total of 10 studies described 9 transitional care programs. Most programs (60%) were nurse/social-worker-led post-discharge phone call programs that provided follow-up reminders and inquired regarding patient concerns. The remaining 40% of programs were comprehensive interdisciplinary case-coordination transitional care programs. Readmissions were reduced by 5% and emergency department visits by 13% among participants of both types of programs compared to historic data. Both programs improved follow-up adherence by 75% compared to historic data.

CONCLUSION

Transitional care programs targeted at injured patients vary in structure and may reduce overall health care use.

A multicenter, citywide report on recurrent violent injury

INTRODUCTION

The incidence of and risk factors for recurrent violent trauma are not well known. This information is needed to focus violence prevention efforts on at-risk cohorts. The purpose of this study was to determine the incidence of and risk factors for recurrence following violent injury in a large urban setting. We hypothesize that the overall incidence of recurrent violent injury is low but there are specific at-risk cohorts.

METHODS

A retrospective, citywide study of patients who sustained blunt assault or penetrating trauma from 2013 to 2019 was performed. Patients were tracked across all trauma centers using their name and date of birth. The primary outcome was incidence of recurrent violent injury, which was calculated by dividing the number of readmitted patients by the number who survived previous admissions due to penetrating trauma or blunt assault. Associations between readmission and injury severity score, abbreviated injury score, age, sex, hospital, mechanism of injury (MOI), and disposition were determined. Kaplan-Meier curves were plotted to determine the incidence of recurrent injury over time. A multivariable Cox proportional hazard model was used to examine the relationships between characteristics at first admission and time-to-readmission.

RESULTS

The recurrent injury rate was 836 patients (6.33%) out of 13,211 injured patients. Male, age 14-45 years old, discharge to jail or left against medical advice, and moderate/severe head injury were associated with re-injury. There was no association between recurrence and mechanism of injury or overall injury severity. Discharge to home was associated with a lower re-injury rate.

CONCLUSION

The low recurrent injury rate despite high injury prevalence suggests injury prevention efforts should target this demographic and their non-injured peers.

Post-Trauma Follow-up Phone Call Shows Lower Readmission Rates for Patients Discharged From Emergency Department Compared to Inpatient Stay

BACKGROUND

Studies show follow-up phone calls decrease readmission rates (RR) in trauma patients and social vulnerabilities may play a role as well. Minimal literature exists comparing RR of trauma patients who required an inpatient stay to those whose treatment was limited to the Emergency Department (ED), as they are at high risk of recidivism. We hypothesized post-trauma follow-up calls would show higher RR for ED patients than those requiring inpatient stay, as well as potentially differing outcomes for minorities.

STUDY DESIGN

A retrospective analysis from 2019-2020 of 1328 trauma patients from UCI Medical Center, discharged from inpatient facilities or the ED. A questionnaire script read by a nurse practitioner to patients via phone call following discharge. Data associated with readmission were captured. Multivariable logistic regression analysis was performed, controlling for patient factors including severity of injury.

RESULTS

Patients discharged from the ED were 47.4% less likely to be readmitted than those who required an inpatient stay (P < .01). However, ED patients were 88.7% less likely to receive a prescription than inpatient stay patients (P < .01). No difference between ED and inpatient discharge contact rates was noted (P < .99). Furthermore, no difference in readmission rates was noted for minorities.

CONCLUSION

Post-trauma follow-up calls showed lower RR for index ED visit patients than those requiring inpatient stay, contrary to expectations. However, ED visit patients were also less likely to receive/fill prescriptions compared to those requiring inpatient stay. Ongoing analysis is warranted to further validate and improve follow-up call programs to ensure equitable health care.

Targeting zero preventable trauma readmissions

BACKGROUND

Nearly 1-in-10 trauma patients in the United States are readmitted within 30 days of discharge, with a median hospital cost of more than $8,000 per readmission. There are national efforts to reduce readmissions in trauma care, but we do not yet understand which are potentially preventable. Our study aims to quantify the potentially preventable readmissions (PPRs) in trauma care to serve as the anchor point for ongoing efforts to curb hospital readmissions and ultimately, bring preventable readmissions to zero.

METHODS

We identified inpatient hospitalizations after trauma and readmissions within 90 days in the 2017 National Readmissions Database (NRD). Potentially preventable readmissions were defined as the Agency for Healthcare Research and Quality-defined Ambulatory Care Sensitive Conditions, in addition to superficial surgical site infection, acute kidney injury/acute renal failure, and aspiration pneumonitis. Mean costs for these admissions were calculated using the NRD. A multivariable logistic regression model was used to characterize the relationship between patient characteristics and PPR.

RESULTS

A total of 1,320,083 patients were admitted for trauma care in the 2017 NRD, and 137,854 (10.4%) were readmitted within 90 days of discharge. Of these readmissions, 22.7% were potentially preventable. The mean cost was $10,001/PPR, resulting in $313,802,278 in cost to the US health care system. Of readmitted trauma patients younger than 65 years, Medicaid or Medicare patients had 2.7-fold increased odds of PPRs compared with privately insured patients. Patients of any age with congestive heart failure had 2.9 times increased odds of PPR, those with chronic obstructive pulmonary disease or complicated diabetes mellitus had 1.8 times increased odds, and those with chronic kidney disease had 1.7 times increased odds. Furthermore, as the days from discharge increased, the proportion of readmissions due to PPRs increased.

CONCLUSION

One-in-five trauma readmissions are potentially preventable, which account for more than $300 million annually in health care costs. Improved access to postdischarge ambulatory care may be key to minimizing PPRs, especially for those with certain comorbidities.

Association of Psychosocial Factors and Hospital Complications with Risk for Readmission After Trauma

BACKGROUND

Unplanned hospital readmissions are associated with morbidity and high cost. Existing literature on readmission after trauma has focused on how injury characteristics are associated with readmission. We aimed to evaluate how psychosocial determinants of health and complications of hospitalization combined with injury characteristics affect risk of readmission after trauma.

MATERIALS AND METHODS

We conducted a retrospective cohort study of adult trauma admissions from July 2015 to September 2017 to Harborview Medical Center in Seattle, Washington. We assessed patient, injury, and hospitalization characteristics and estimated associations between risk factors and unplanned 30-d readmission using multivariable generalized linear Poisson regression models.

RESULTS

Of 8916 discharged trauma patients, 330 (3.7%) had an unplanned 30-d readmission. Patients were most commonly readmitted with infection (41.5%). Independent risk factors for readmission among postoperative patients included public insurance (adjusted Relative Risk (aRR) 1.34, 95% CI 1.02-1.76), mental illness (aRR 1.39, 1.04-1.85), and chronic renal failure (aRR 2.17, 1.39-3.39); undergoing abdominal, thoracic, or neurosurgical procedures; experiencing an index hospitalization surgical site infection (aRR 4.74, 3.00-7.50), pulmonary embolism (aRR 3.38, 2.04-5.60), or unplanned ICU readmission (aRR 1.74, 1.16-2.62); shorter hospital stay (aRR 0.98/d, 0.97-0.99), and discharge to jail (aRR 4.68, 2.63-8.35) or a shelter (aRR 4.32, 2.58-7.21). Risk factors varied by reason for readmission. Injury severity, trauma mechanism, and body region were not independently associated with readmission risk.

CONCLUSIONS

Psychosocial factors and hospital complications were more strongly associated with readmission after trauma than injury characteristics. Improved social support and follow-up after discharge for high-risk patients may facilitate earlier identification of postdischarge complications.
