Three predictive scores compared in a retrospective multicenter study of nonunion tibial shaft fracture

BACKGROUND Delayed union,malunion,and nonunion are serious complications in the healing of fractures.Predicting the risk of nonunion before or after surgery is challenging.AIM To compare the most prevalent predictive scores of nonunion used in clinical practice to determine the most accurate score for predicting nonunion.METHODS We collected data from patients with tibial shaft fractures undergoing surgery from January 2016 to December 2020 in three different trauma hospitals.In this retrospective multicenter study,we considered only fractures treated with intramedullary nailing.We calculated the tibia FRACTure prediction healING days(FRACTING)score,Nonunion Risk Determination score,and Leeds-Genoa Nonunion Index(LEG-NUI)score at the time of definitive fixation.RESULTS Of the 130 patients enrolled,89(68.4%)healed within 9 months and were classified as union.The remaining patients(n=41,31.5%)healed after more than 9 months or underwent other surgical procedures and were classified as nonunion.After calculation of the three scores,LEG-NUI and FRACTING were the most accurate at predicting healing.CONCLUSION LEG-NUI and FRACTING showed the best performances by accurately predicting union and nonunion.

Delta shock index predicts injury severity,interventions,and outcomes in trauma patients:A 10-year retrospective observational study

BACKGROUND Most trauma occurs among young male subjects in Qatar.We examined the predictive values of the delta shock index(DSI),defined as the change in the shock index(SI)value from the scene to the initial reading in the emergency unit(i.e.,subtracting the calculated SI at admission from SI at the scene),at a Level 1 trauma center.AIM To explore whether high DSI is associated with severe injuries,more interventions,and worse outcomes[i.e.,blood transfusion,exploratory laparotomy,ventilator-associated pneumonia,hospital length of stay(HLOS),and in-hospital mortality]in trauma patients.METHODS A retrospective analysis was conducted after data were extracted from the National Trauma Registry between 2011 and 2021.Patients were grouped based on DSI as low(≤0.1)or high(>0.1).Data were analyzed and compared usingχ2 and Student’s t-tests.Correlations between DSI and injury severity score(ISS),revised trauma score(RTS),abbreviated injury scale(AIS),Glasgow coma scale(GCS),trauma score-ISS(TRISS),HLOS,and number of transfused blood units(NTBU),were assessed using correlation coefficient analysis.The diagnostic testing accuracy for predicting mortality was determined using the validity measures of the DSI.Logistic regression analysis was performed to identify predictors of mortality.RESULTS This analysis included 13212 patients with a mean age of 33±14 years,and 24%had a high DSI.Males accounted for 91%of the study population.The trauma activation level was higher in patients with a high DSI(38%vs 15%,P=0.001).DSI correlated with RTS(r=-0.30),TRISS(r=-0.30),NTBU(r=0.20),GCS(r=-0.24),ISS(r=0.22),and HLOS(r=0.14)(P=0.001 for all).High DSI was associated with significantly higher rates of intubation,laparotomy,ventilator-associated pneumonia,massive transfusion activation,and mortality than low DSI.For mortality prediction,a high DSI had better specificity,negative predictive value,and negative likelihood ratio(77%,99%,and 0.49%,respectively).After adjusting for age,emergency medical services time,GCS score,and ISS,multivariable regression analysis showed that DSI was an independent predictor of mortality(odds ratio=1.9;95%confidence interval:1.35-2.76).CONCLUSION In addition to sex-biased observations,almost one-quarter of the study cohort had a higher DSI and were mostly young.High DSI correlated significantly with the other injury severity scores,which require more time and imaging to be ready to use.Therefore,DSI is a practical,simple bedside tool for triaging and prognosis in young patients with trauma.

Application of pediatric ocular trauma score in pediatric open globe injuries

AIM:To evaluate the predictive value of pediatric penetrating ocular trauma score(POTS)on the visual outcome in children with open globe injury.METHODS:A retrospective study in 90 children(60 males and 30 females)aged 1-15 y(average,7.48±2.86 y)with penetrating ocular trauma was performed.Each patient’s POTS was calculated.The effects of POTS on final visual acuity(FVA)were examined.Correlation between factors affecting POTS and the FVA was established.RESULTS:All patients presented with single-eye trauma.The follow-up time was 3-21 mo(average,10.23±3.54 mo).Among the 90 cases of penetrating wounds,71 eyes(78.89%)were injured in Zone I(wound involvement limited to the cornea,including the corneoscleral limbus),17 eyes(18.89%)were injured in Zone II(wound involving the sclera and no more posterior than 5 mm from the corneoscleral limbus),and 2 eyes(2.22%)were injured in Zone III(wound involvement posterior to the anterior 5 mm of the sclera).Analysis of POTS and FVA showed important correlation between them(r=0.414,P=0.000).Initial visual acuity(P=0.00),age(P=0.02),injury location(P=0.002),traumatic cataract(P=0.00),vitreous hemorrhage(P=0.027),retinal detachment(P=0.003),and endophthalmitis(P=0.03)were found to be statistically significant factors for the FVA outcome.CONCLUSION:Ocular trauma presents serious consequences and poor prognosis in children.The POTS may be a reliable prognostic tool in children with open globe injury.

Reliability of the ocular trauma score for the predictability of traumatic and post-traumatic retinal detachment after open globe injury

AIM: To elucidate the question of whether the ocular trauma score(OTS) and the zones of injury could be used as a predictive model of traumatic and post traumatic retinal detachment(RD) in patients with open globe injury(OGI).METHODS: A retrospective observational chart analysis of OGI patients was performed. The collected variables consisted of age, date, gender, time of injury, time until repair, mechanism of injury, zone of injury, injury associated vitreous hemorrhage, trauma associated RD, post traumatic RD, aphakia at injury, periocular trauma and OTS in cases of OGI. RESULTS: Totally 102 patients with traumatic OGI with a minimum of 12 mo follow-up and a median age at of 48.6 y(range: 3-104 y) were identified. Final best corrected visual acuity(BCVA) was independent from the time of repair, yet a statistically significant difference was present between the final BCVA and the zone of injury. Severe trauma presenting with an OTS score Ⅰ(P<0.0001) or Ⅱ(P<0.0001) revealed a significantly worse BCVA at last follow up when compared to the cohort with an OTS score >Ⅲ. OGI associated RD was observed in 36/102 patients(35.3%), whereas post traumatic RD(defined as RD following 14 d after OGI) occurred in 37 patients(36.3%). OGI associated RD did not correlate with the OTS and the zone of injury(P=0.193), yet post traumatic RD correlated significantly with zone Ⅲ injuries(P=0.013). CONCLUSION: The study shows a significant association between lower OTS score and zone Ⅲ injury with lower final BCVA and a higher number of surgeries, but only zone Ⅲ could be significantly associated with a higher rate of RD.

Predictive value and applicability of ocular trauma scores and pediatric ocular trauma scores in pediatric globe injuries

AIM: To evaluate the predictive value and applicability of Ocular Trauma Score(OTS) and Pediatric Ocular Trauma Score(POTS) for closed and open globe injuries in the pediatric group.METHODS: A retrospective study of closed and open globe injuries in children age of 0-18-year-old between 2012-2019 was conducted.Medical records were collected,and injuries were classified using Birmingham Eye Trauma Terminology System(BETTS).The predictive value and applicability of both OTS and POTS to final visual acuity(VA) were analyzed.RESULTS: Of 84 patients,59(70.2%) presented with closed globe injuries(CGI) and 25(29.8%) with open globe injuries(OGI).The mean of initial VA was 0.832±0.904 log MAR.OTS and POTS was calculated.Initial VA(P<0.001) and traumatic cataract(P<0.001) were significantly associated with visual outcome,followed by organic/unclean wound (P=0.001),delay of surger y(P=0.001),iris prolapse(P=0.003),and globe rupture(P=0.008).A strong correlation between OTS and POTS and final VA(r=-0.798,P<0.001;r=-0.612,P<0.001) was found.OTS was more applicable in all age group of pediatric and in contrast to POTS,it was designed for 0-15 years old.POTS requires eleven parameters and OTS six parameters.Even though initial VA was not available,we could still calculate into POTS equation.CONCLUSION: OTS and POTS are highly predictive prognostic tools for final VA in CGI and OGI's in children.

Impact of lockdown policies during the COVID-19 outbreak on a trauma center of a tertiary hospital in China

BACKGROUND Coronavirus disease 2019(COVID-19)is a major and costly public health emergency.AIM To investigate the impact of China’s lockdown policies during the COVID-19 outbreak on the level I trauma center of a tertiary comprehensive hospital of Traditional Chinese Medicine.METHODS All patients admitted to our trauma center during a lockdown in 2020 and the same period in 2019 were enrolled.We collected data on demographics,daily visits,injury type,injury mechanism,injury severity score,and patient management for comparative analysis.RESULTS The total number of patients in the trauma center of our hospital decreased by 50.38%during the COVID-19 Lockdown in 2020 compared to the same period in 2019.The average number of trauma visits per day in 2019 was 47.94,compared to 23.79 in 2020.Comparing the patients’demographic data,loss of employment was the most predominate characteristic in 2020 compared to 2019,while there was no significant difference in gender,age,and marital status between both periods.During the lockdown period,the proportion of traffic accident-related injuries,injuries due to falls greater than 1.5 m,and mechanical injuries decreased significantly,whereas the proportion of injuries caused by falls less than 1.5 m,cuts,assault,bites,and suicidal tendencies and other injuries increased relatively.In addition,the proportion of patients with minor injuries increased and serious injuries decreased during the lockdown.The hospitalization rate increased significantly,and there was no significant difference in emergency surgery and death rates.CONCLUSION The lockdown policies during the COVID-19 outbreak significantly altered the number and mechanism of traumatic events in our hospital,which can be monitored regularly.Our results suggest that mandatory public health prevention and control measures by the government can reduce the incidence of traumatic events and the severity of traumatic injuries.Emergency surgery and mortality rates remain high,increased because of factors such as family injury and penetrating injury,and hospitalization rates have increased significantly.Therefore,our trauma center still needs to be fully staffed.Finally,from the perspective of the injury mechanism,indoor trauma is a major risk during a lockdown,and it is particularly important to develop prevention strategies for such trauma to reduce the medical burden of the next catastrophic epidemic.

Initial suction drainage decreases severe postoperative complications after pancreatic trauma:A cohort study

BACKGROUND Few studies have addressed the question of which drain types are more beneficial for patients with pancreatic trauma(PT).AIM To investigate whether sustained low negative pressure irrigation(NPI)suction drainage is superior to closed passive gravity(PG)drainage in PT patients.METHODS PT patients who underwent pancreatic surgery were enrolled consecutively at a referral trauma center from January 2009 to October 2021.The primary outcome was defined as the occurrence of severe complications(Clavien-Dindo grade≥Ⅲb).Multivariable logistic regression was used to model the primary outcome,and propensity score matching(PSM)was included in the regression-based sensitivity analysis.RESULTS In this study,146 patients underwent initial PG drainage,and 50 underwent initial NPI suction drainage.In the entire cohort,a multivariable logistic regression model showed that the adjusted risk for severe complications was decreased with NPI suction drainage[14/50(28.0%)vs 66/146(45.2%);odds ratio(OR),0.437;95%confidence interval(CI):0.203-0.940].After 1:1 PSM,44 matched pairs were identified.The proportion of each operative procedure performed for pancreatic injury-related and other intra-abdominal organ injury-related cases was comparable in the matched cohort.NPI suction drainage still showed a lower risk for severe complications[11/44(25.0%)vs 21/44(47.7%);OR,0.365;95%CI:0.148-0.901].A forest plot revealed that NPI suction drainage was associated with a lower risk of Clavien-Dindo severity in most subgroups.CONCLUSION This study,based on one of the largest PT populations in a single high-volume center,revealed that initial NPI suction drainage could be recommended as a safe and effective alternative for managing complex PT patients.
