RESUMEN
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.

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.

OBJECTIVE: Temporary intravascular shunts (TIVSs) are commonly used as a damagecontrol procedure in trauma settings. Currently, there is scarce literature in the civilian field, and what there is is limited to large trauma centers with multiple resources. Therefore, we aimed to describe TIVS usage, and the outcomes of that usage, at Puerto Rico Trauma Hospital. MATERIALS AND METHODS: This is a case series conducted from 2009 to 2013 with 32 patients who suffered vascular trauma, of which 13 needed TIVSs. Data related to age, trauma mechanism, injured vessel, type of shunt, Glasgow Coma Scale, vital signs, and mortality were collected. The analysis was carried out using descriptive statistics. This protocol was approved by the IRB of the Medical Sciences Campus. RESULTS: The most frequent mechanism of injury was a gunshot (11/13; 84.6%). The most commonly injured vessel was the superficial femoral artery. Indwelling time ranged from 6 to 96 hours. Only 2 of the 13 (15.4%) patients with shunts reported thrombosis. Furthermore, we performed 4 (30.7% of the patients) prophylactic fasciotomies and 4 (30.7% of the patients) amputations; 4 of the 13 (30.7%) patients died from unrelated causes. CONCLUSION: Our results are consistent with those in the literature, which supports our contention that a TIVS can be an effective component of damage-control vascular surgery and can, in both military and civilian settings, aid in extremity amputation prevention. Furthermore, it has been established that a TIVS can be fashioned from any available hollow tube. However, further research is needed to evaluate the safety of an improvised catheter of this nature.

OBJECTIVE: Recent literature has suggested that trauma is heterogenic and that physiological response to it differs between sexes. The study represented in this manuscript aimed to describe gender differences in the mortality rates of trauma patients at the Puerto Rico Trauma Hospital (PRTH). MATERIALS AND METHODS: This was a cross-sectional study performed at PRTH. A total of 14,874 injured patients admitted to the hospital from 2002 to 2011 were included in the sample and divided into 2 groups, based on sex. Pearson's chi-square test was employed for categorical variables and the Mann-Whitney U test for continuous ones. A logistic regression model was undertaken to estimate the association between gender and study outcomes, after adjusting for confounders. A p-value lower than 0.05 was an indication of statistical significance. IRB approval was received. RESULTS: The most common injury areas for women were the chest (32.50%), followed by the extremities (25.83%) and the head/neck (21.51%). Road traffic collisions (RTCs) (45.08%), falls (19.62%), and pedestrian accidents (16.08%) were the most common injury mechanisms for women. The highest frequency of RTC injuries (57.52%) among females occurred in patients who were from 18 to 39 years old. Females 65 years old and older exhibited the highest frequency of falls (39.78%) and pedestrian injuries (25.14%). Males 17 years and under were more likely to have an Injury Severity Score (ISS) of 15 or greater (AOR = 1.56; 95% CI: 1.19-2.03) than were their female counterparts; and, overall, males were more likely to have a Glasgow coma score (GCS) under 9 (AOR = 1.30; 95% CI: 1.11-1.53) than females were. Despite these results, there were no differences between gender mortality rates (AOR = 1.04; 95% CI: 0.86-1.25). CONCLUSION: Our results suggest that there is no sex dimorphism conferring protection on females. Future studies should be conducted to assess this issue.

PURPOSE: Substance misuse has long been recognized as a major predisposing risk factor for traumatic injury. However, there still exists no clear scientific consensus regarding the impact of drug use on patient outcomes. Therefore, this study aims to evaluate the demographic profile, hospital-course factors, and outcomes of trauma patients based on their toxicology. METHODS: This is a non-concurrent cohort study of 3709 patients treated at the Puerto Rico Trauma Hospital during 2002-2018. The sample was divided into four groups according to their toxicology status. Statistical techniques used included Pearson's chi-square test, Spearman correlation, and negative binomial and logistic regressions. RESULTS: Admission rates for marijuana (rho = 0.87) and marijuana and cocaine positive (rho = 0.68) patients increased. Positive toxicology patients underwent surgery more often than negative testing patients (marijuana: 68.7%, cocaine: 65.6%, marijuana & cocaine: 69.8%, negative: 57.0%). Among patients with non-penetrating injuries, a positive toxicology for cocaine or marijuana was linked to a 48% and 42% increased adjusted risk of complications, 37% and 27% longer TICU LOS, and 32% and 18% longer hospital LOS, respectively. CONCLUSION: Our results show an association between positive toxicology for either marijuana, cocaine, or both with higher need for surgery. Additionally, our results show an increase in complications, TICU LOS, and hospital LOS among non-penetrating trauma patients testing positive for marijuana or cocaine. Therefore, this study provides valuable information on the clinical profile of patients with positive toxicology, suggesting they might benefit from more aggressive management.

PURPOSE: Although trauma represents a leading cause of morbidity and mortality worldwide, there is limited and heterogeneous evidence regarding trauma recidivism and its outcomes. This analysis determined the rate and independent risk factors of trauma recidivism and compared the first and second injury episode among recidivists. METHODS: An IRB-approved retrospective cohort study was performed with data from the Puerto Rico Trauma Hospital Registry. Bivariate analyses were done using Pearson's Chi squared, Wilcoxon rank-sum, McNemar, Stuart-Maxwell or Wilcoxon signed-rank tests, as appropriate. Independent predictors for recidivism were determined through a logistic regression model. Statistical significance was set at p < 0.05. RESULTS: 24,650 patients were admitted to the hospital during 2000-2017. Recidivism rate was 14 per 1,000 patients discharged alive. Males and individuals aged 15-24 years old were 3.88 (95% CI: 2.21-6.80) and 3.80 (95% CI: 2.24-6.46) times more likely to be recidivists, respectively. Contrariwise, an ISS [Formula: see text] 25 [adjusted odds ratio (AOR) = 0.44; 95% CI: 0.28-0.68] and a GCS [Formula: see text] 8 (AOR = 0.56; 95% CI 0.34-0.92) were protective factors. Furthermore, recidivists exhibited less in-hospital mortality than their non-recidivist counterparts (7.2% vs. 10.7%; p = 0.045). For recidivists, the median (interquartile range) time to reinjury was 42 (59) months; and the second injury episode was more severe than the first one, as the proportion of patients with ISS [Formula: see text] 25 increased (7.9% vs. 14.1%; p = 0.022). CONCLUSION: The independent predictors of trauma recidivism and the median time to reinjury identified in this study provide valuable information to the development of prevention strategies aimed at reducing the burden of injury.

Objectives: We aimed to explore the influence of mental disorders on the risk of developing complications and in-hospital mortality after trauma. Methods: We conducted an institutional review board-approved cohort study of 23 500 adult patients admitted to the Puerto Rico Trauma Hospital from 2002 to 2019. Participants were divided into 2 groups according to the presence or absence of psychiatric illnesses. Logistic regressions were employed to investigate the effect of mental illness on study outcomes. Results: Psychiatric illness was associated with higher risk of complications; this risk increased with age. The pattern was accentuated for those with substance use disorders (SUD) and attenuated for those with non-substance-related diagnoses (NSRD). Psychiatric patients with Glasgow Coma Scale (GCS) scores of 15 had a 42% (95% CI 1.17 to 1.73) higher risk of dying, while the opposite was seen for those with scores <15 (adjusted OR=0.79; 95% CI 0.64 to 0.99). SUD was associated with a 51% (95% CI 1.21 to 1.88) higher risk of death in patients with GCS scores of 15, while NSRD was linked to a 49% (95% CI 0.33 to 0.79) lower odds of death among subjects with scores <15. Conclusions: Our results suggest that trauma patients with SUD are at increased risk of developing complications and those with SUD and GCS scores of 15 are at increased risk of death. Mental health screening is an essential component of the management of trauma patients. Stratifying based on mental health disorders may be helpful during the clinical management of trauma patients, as those with SUD may benefit from more aggressive management. Level of evidence: Level 4, prognostic and epidemiological study. Study type: Original retrospective cohort study.
RESUMEN
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.
RESUMEN
OBJECTIVES: The hazardous environmental conditions hurricanes create might increase injury incidence almost 7 times. Therefore, a cohort study was performed at the Puerto Rico Trauma Hospital to compare morbidity and mortality patterns of patients after Hurricane Maria with a control period. METHODS: Admissions from September 20, 2017, through January 20, 2018, constituted the post-Maria period (473 patients); the corresponding months of the previous year comprised the pre-Maria period (439 patients). Comparisons were done using Pearson's chi-square or Mann-Whitney U-tests, as appropriate. A logistic regression was performed to assess the association between mortality and the study period. RESULTS: Postlandfall admissions among patients aged 40-64 y increased by 6.6%, while among subjects between ages 18 and 39 y dropped by 7.0% (P = 0.03). Falls, gunshots, and burns were the injury mechanisms that varied the most across the exposure period. The median Injury Severity Score (13 vs 12; P = 0.05) and the frequency of Glasgow Coma Scale scores ≤8 (17.1% vs 10.9%; P = 0.03) were higher among poststorm patients. Moreover, a 2-fold (odds ratio = 1.93; 95% CI: 1.07-3.47) increase in mortality was observed after Maria, when adjusting for covariates. CONCLUSIONS: Following a hurricane, trauma centers might expect an older population, with more severe injuries and a 2-fold increased mortality risk.
RESUMEN
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.
RESUMEN
This study aimed to describe the distribution of injury mechanisms and to assess the impact of those mechanisms on the morbidity and mortality of trauma. All patients admitted to Puerto Rico Trauma Hospital (2002-2011) for road-traffic collisions (RTCs, 5,371), gunshot wounds (GSWs, 2,946), falls (2,319), pedestrian accidents (1,652), and stab wounds (SWs, 1,073) were selected. Gunshot victims were 1.19 (95%CI: 1.07-1.33) times as likely as road-traffic victims to have an ISS ≥25. Pedestrians were 1.76 (95%CI: 1.49-2.09) times more likely to have a GCS ≤8 than road-traffic victims were. The risk of dying was 2.64 (95%CI: 2.20-3.16) times higher for gunshot victims and 1.51 (95%CI: 1.23-1.86) times higher for pedestrians compared to patients who had had RTCs. Gunshot victims and pedestrians had the worst clinical outcomes. Accordingly, these patients should receive the most aggressive clinical management. Furthermore, it is imperative to develop public health campaigns on trauma prevention.
