Surgical Rib Fixation is Associated With Lower Mortality in Patients With Traumatic Rib Fractures.

INTRODUCTION: Nonoperative management (NOM) along with supportive care has been the adopted approach for traumatic rib fractures; however, surgical approaches have emerged recently to treat this common pathology. Despite this, there are no guidelines for surgical rib fixation in patients with traumatic rib fractures. METHODS: An institutional review board-approved retrospective cohort study was performed at the Puerto Rico Trauma Hospital aiming to compare the outcomes and complications between patients with traumatic rib fractures who undergo surgical fixation and their counterparts with NOM. The study period comprised from January 2016 through July 2020. Outcomes were evaluated with negative binomial and logistic regressions. RESULTS: Fifty patients were identified for the surgical rib fixation group, who were matched to 150 patients who received NOM. The majority of patients were male (91.5%), with a median (interquartile range) age of 53 (29) years. Concomitant chest injuries were significantly more prevalent in the operative group, such as flail segment (P < 0.001), number of fractures (P < 0.001), and displaced rib fractures (P < 0.001). Although hospital length of stay was 25% (95% confidence interval: 1.02-1.54) longer in the surgical group, this intervention was associated with an 85% (95% confidence interval: 0.03-0.70) lower mortality rate when compared to conservative management. CONCLUSIONS: Rib fixation may offer some benefits in selected patients with traumatic rib fractures, such as those with bilateral rib fractures, multiple displaced rib fractures, flail segment, and concomitant thoracic injuries. This study may serve as a guide for treatment strategy and patient selection regarding the surgical management of traumatic rib fractures.

Elderly Admission Trends at the Puerto Rico Trauma Hospital: A Time-Series Analysis.

INTRODUCTION: The aging process places the elderly, a worldwide increasing age group, at an increased risk for trauma. This study aims to explore changes over time in admission rates, sociodemographical, clinical, and injury-related data in elderly patients (aged ≥65 y) admitted to the Puerto Rico Trauma Hospital (PRTH) during 2000-2019. MATERIALS AND METHODS: A time-series analysis was conducted. Admission rates were analyzed by fitting an exponential growth curve model. Trends were assessed using the Cochrane-Armitage and Cuzick tests for categorical and continuous data, respectively. RESULTS: Elderly admission rates to the PRTH have shown growth over the past 2 decades, from 6.2 cases per 100 overall admissions in 2000 to 18.2 in 2019. This trend is projected to continue with estimated 24.8 (95% CI: 21.7-27.8) cases per 100 overall admissions in 2023. Trends for mechanisms of injury such as motor vehicle accidents and pedestrians showed a significant decrease, whereas falls presented a clear positive trend, showing an increase from 25.6% in 2000-2004 to 46.2% in 2015-2019. Both Injury Severity Score ≥25 and Glasgow Coma Scale ≤8 declined significantly through time. Finally, in-hospital mortality presented a decreasing trend from 31.7% in 2000-2004 to 21.5% in 2015-2019. CONCLUSIONS: Our analysis demonstrates an increase over time in elderly admissions, especially fall-related trauma. Also, it projects this upward trend will continue. This imposes new challenges for PRTH and other healthcare services and is a gateway for the implementation of adapted clinical management.

The effect of the lockdown executive order during the COVID-19 pandemic in recent trauma admissions in Puerto Rico.

BACKGROUND: The COVID-19 pandemic led to world-wide restrictions on social activities to curb the spread of this disease. Very little is known about the impact of these restrictions on trauma centers. Our objective was to determine the effect of the pandemic-associated lockdown on trauma admissions, patient's demographics, mechanisms of injury, injury severity, and outcomes in the Puerto Rico Trauma Hospital. METHODS: An IRB-approved quasi-experimental study was performed to assess the impact of the restrictions by comparing trauma admissions during the lockdown (March 15, 2020 - June 15, 2020) with a control period (same period in 2017-2019). Comparisons were done using the Pearson's chi-square test, Fisher exact test, or Mann-Whitney U test, as appropriate. A negative binomial model was fitted to estimate the incidence rate ratio for overall admissions among pre-lockdown and during-lockdown periods. Statistical significance was set at p < 0.05. RESULTS: A total of 308 subjects were admitted during the quarter of study for 2017; 323, for 2018; 347, for 2019; and 150, for 2020. The median (interquartile range) age of patients rose significantly from 40 (33) years to 49 (30) years (p < 0.001) for the lockdown period compared to the historical period. Almost all mechanisms of injury (i.e., motor vehicle accident, assault, pedestrian, burn, suicide attempt, other) had a slight non-significant reduction in the percentage of patients presenting with an injury. Instead, falls experienced an increase during the lockdown period (18.9% vs. 26.7%; p = 0.026). Moreover, the proportion of severe cases decreased, as measured by an injury severity score (ISS) > 15 (37.3% vs. 26.8%; p = 0.014); while there were no differences in the median hospital length of stay and the mortality rate between the comparison groups. Finally, the decrease in overall admissions registered during the lockdown accounts for a 59% (IRR 0.41; 95% CI 0.31-0.54) change compared to the pre-lockdown period, when controlling for sex, age, mechanism of injury, and ISS. CONCLUSIONS: Following periods of social isolation and curfews, trauma centers can expect drastic reductions in their overall patient volume with associated changes in trauma patterns. Our findings will help inform new interventions and improve healthcare preparedness for future or similar circumstances.

Epidemiology of traumatic falls after Hurricane Maria in Puerto Rico.

BACKGROUND: Hurricanes are among the most devastating natural disasters, playing a significant role in public health. Currently, the epidemiology of fall-related injuries after the occurrence of a tropical storm is not well described. This study aims to compare the demographical patterns, clinical profile, hospital course, and costs of patients admitted to the Puerto Rico Trauma Hospital before and after Hurricane Maria. METHODS: A retrospective study was performed to compare fall-related injuries after the hurricane (September 20, 2017 - January 20, 2018) with a control period (same period in 2014-2016). Comparison between the groups was done using chi-square, Mann-Whitney test, and logistical regression. RESULTS: After the hurricane, there was an increase in the proportion of fall-related admissions in subjects aged 40-64 years (39.2% vs. 50.6%) and a decrease among those aged 18-39 years (16.0% vs. 5.9%), when compared with the previous years. A greater proportion of patients presented with work related injuries (3.9% vs. 9.4%). No significant differences were identified for sex, Glasgow Coma Scale, Injury Severity Score, and hospital outcomes (hospital and intensive care unit days, mechanical ventilation, and mortality). Intracranial injuries were marginally higher post-Maria (p = 0.06). In multivariate analysis, during the post-Maria period, an increased risk of fall-related injuries was observed among subjects ≥40 years (OR: 3.20) and injuries related to recovery work (OR: 2.64) (p < 0.05). CONCLUSIONS: Our study shows that there is an increased risk of fall-related injuries among middle-aged individuals after a hurricane, causing significant changes in epidemiology. This study helps to elucidate the health consequences of falls and, in doing so, improves healthcare preparedness, interventions, and planning for future natural disasters.
