RESUMEN
ABSTRACT Purpose: This study aimed to evaluate the mechanisms of injury and types of orbital fractures and their relation to concurrent commotio retinae. Methods: This retrospective study evaluated the records of patients with orbital fractures whose diagnoses had been confirmed by computer tomography between July 2017 and September 2019. Patient demographics, the circumstances of injury, ophthalmic examination results, and radiological findings were tabulated. Statistical analysis of the data used two-tailed student's t-tests, chi-squared tests, and odds ratio calculations. Statistical significance was set at p<0.05. Results: Of the 204 patients with orbital fractures included in this study, 154 (75.5%) were male. The mean age was 42.1 years. Orbital fractures involving one orbital wall (58.8%) were more common than those affecting multiple walls (41.2%). The majority of fractures affected the inferior wall (60.3%), with the medial walls being the next most frequently affected (19.6%). The most common cause of injury was assault (59.3%), and the second most common was falls (24%). Commotio retinae was observed in 20.1% of orbital fracture cases and was most associated with injuries caused by assault (OR=5.22, p<0.001) and least associated with those caused by falls (OR=0.06, p<0.001). Eye movement restrictions were more common in central than peripheral commotio (OR=3.79, p=0.015) and with medial wall fractures than fractures to other orbital walls (OR=7.16, p<0.001). The odds of commotio were not found to be higher in patients with multi-walled orbital fractures than in those with single-walled fractures (p=0.967). Conclusions: In the study population, assault was the most common cause of orbital fractures and resulted in commotio retinae than other causes. Ophthalmologists should be aware of the likelihood of commotio retinae in patients with orbital fractures resulting from assault, regardless of the extent of the patient's injuries.
RESUMO Objetivo: Este estudo visou avaliar os mecanismos da lesão e os tipos de fraturas orbitárias e sua relação com commotio retinae simultânea. Métodos: Este estudo retrospectivo avaliou registros de pacientes com fraturas orbitárias cujos diagnósticos foram confirmados por tomografia computadorizada entre julho de 2017 e setembro de 2019. Foram registrados os dados demográficos, circunstâncias da lesão, os resultados do exame oftalmológico e achados radiológicos. A análise estatística dos dados usou os testes de t-Student bicaudal, qui-quadrado e cálculos de odds ratio. O significado estatístico foi fixada em p<0,05. Resultados: Dos 204 pacientes com fraturas orbitárias incluídos neste estudo, 154 (75,5%) eram sexo masculino (75,5%). A média de idade foi de 42,1 anos. As fraturas orbitárias envolvendo uma parede orbital (58,8%) foram mais comuns do que as que acometeram várias paredes (41,2%). A maioria das fraturas acometeu a parede inferior (60,3%), sendo as paredes mediais as próximas mais frequentemente afetadas (19,6%). A causda mais comum de lesão foi agressão (59,3%), e a segunda mais comum foi queda (24%). A commotio retinae foi observada em 20,1% dos casos de fratura orbital e foi mais associada a lesões causadas por agressão (OR=5,22, p<0,001) e menos associada com aquelas causadas por quedas (OR=0,06, p<0,001). As restrições de movimentos oculares eram mais comuns na comoção central do que na periférica (OR=3,79, p=0,015) e com fraturas da parede medial do que com fraturas de outras paredes orbitais (OR=7,16, p<0,001). As chances de comoção não foram maiores em pacientes com fraturas orbitais de paredes múltiplas do que naqueles com fraturas de parede simples (p=0,967). Conclusões: Na população do estudo, a agressão foi a causa mais comum de fraturas orbitais e resultou em commotio retinae mais grave do que qualquer outra causa. Os oftalmologistas devem estar cientes da probabilidade de commotio retinae em pacientes com fraturas orbitais resultantes de agressão, independentemente da extensão das lesões do paciente.

RESUMEN
ABSTRACT Purpose: We aimed to study the characteristics of ocular trauma, an important but largely preventable global cause of blindness, in the United States. Methods: Retrospective chart review of the National Trauma Data Bank (2008-2014) was performed. All patients with ocular trauma were identified using ICD-9CM codes. The collected data were statistically analyzed with student's t-test, Chi-squared test, and logistic regression analysis performed using the SPSS software. The significance was set at p<0.05. Results: It was found that 316,485 (5.93%) of the 5,336,575 admitted trauma patients had ocular injuries. Their mean (SD) age was 41.8 (23) years, and most of them were men (69.4%). Race/ethnicity distribution was White 66.1%, Black 15.1%, and Hispanic 12.3%. The common injuries were orbital 39.5% and eye/adnexa contusions 34%. Associated traumatic brain injury was present in 58.2%. The frequent mechanisms were falls 25.5%, motor vehicle accident-occupant 21.8%, and struck by/against 17.6%. Patients <21 years of age had higher odds of cut/pierce injuries (OR=3.29, 95%CI=3.07-3.51) than the other age groups, those aged 21-64 years had higher odds of motor vehicle accident-cyclist (OR=4.95, 95%CI=4.71-5.19), and those >65 years had higher odds of falls (OR=16.75, 95%CI=16.39-17.12); p<0.001. The Blacks had a greater likelihood of firearm injuries (OR=3.24, 95%CI=3.10-3.39) than the other racial/ethnic groups, the Hispanics experienced more of cut/pierce injuries (OR=2.01, 95%CI=1.85-2.18), and the Whites experienced more of falls (OR=2.3, 95%CI=2.3-2.4); p<0.001. The Blacks (OR=3.41, 95%CI=3.34-3.48) and Hispanics (OR=1.75, 95%CI=1.71-1.79) mostly suffered assaults, while the Whites suffered unintentional injuries (OR=2.78 95%CI=2.74-2.84); p<0.001. Optic nerve/visual pathway injuries had the greatest association with very severe injury severity scores (OR=3.27, 95%CI=3.05-3.49) and severe Glasgow Coma Scores (OR=3.30, 95%CI=3.08-3.54); p<0.001. The mortality rate was 3.9%. Conclusions: Male preponderance and falls, motor vehicle accident-occupant, and struck by/against mechanisms agree with the previous reports. The identified demographic patterns underscore the need to develop group-specific preventive measures.
RESUMO Objetivo: O trauma ocular é uma causa importante e amplamente evitável de cegueira em todo o mundo. Nosso objetivo é estudar suas características nos EUA. Métodos: Revisão retrospectiva do National Trauma Data Bank (2008-2014). Todos os pacientes com trauma ocular foram identificados com códigos CID-9CM. Os dados coletados foram analisados estatísticamente e o teste t de student foi utilizado. As análises qui-quadrado e de regressão logística foram realizadas com o software SPSS. A significância foi estabelecida em p<0,05. Resultados: 316.485 (5,93%) de 5.336.575 pacientes internados com trauma, apresentaram lesões oculares. A média (DP) de idade foi de 41,8 (23) anos. A maioria era do sexo masculino (69,4%). A distribuição raça/etnia foi branca: 66,1%, negra; 15,1% e hispânica: 12,3%. As lesões comuns foram orbitárias: 39,5% e contusões dos olhos/anexos: 34%. A maioria (58,2%) teve lesão cerebral traumática. Os mecanismos frequentes foram: quedas: 25,5%, acidente com veículos motorizados: 21,8% e acidentes atingidos por algo/contra algo: 17,6%. Os pacientes <21 anos apresentaram chance aumentada de lesões com corte/perfuração (RC=3,29; IC95% = 3,07-3,51) do que outras faixas etárias, aqueles entre 21-64 anos responderam por acidente automobilístico-ciclista: (RC=4,95; IC95% = 4,71-5,19) e aqueles >65 anos foram vítimas de quedas (RC=16,75; IC 95% = 16,39-17,12); p<0,001. Os negros apresentaram maior probabilidade de lesões por arma de fogo (RC=3,24; IC95% = 3,10-3,39) do que outras raças/etnias e os hispânicos tiveram mais lesões de corte/perfuração (RC=2,01; IC95%= 1,85-2,18) enquanto os brancos tiveram mais quedas: (RC=2,3; IC95%= 2,3-2,4); p<0,001. Os negros (RC=3,41; IC95% = 3,34-3,48) e os hispânicos (RC=1,75; IC95% = 1,71-1,79) sofreram principalmente agressões e os brancos tiveram lesões não intencionais (RC=2,78; IC95% 2,74-2,84); p<0,001. Lesões do nervo óptico/via visual apresentaram maior associação com escore de gravidade de lesão muito grave (RC=3,27; IC95%= 3,05-3,49) e escores graves de Coma de Glasgow (RC=3,30; IC95%= 3,08-3,54); p<0,001. A taxa de mortalidade foi de 3,9%. Conclusões: Houve preponderância masculina a quedas, a acidentes com veículo motorizado atingidos por algo/contra algo conforme os relatos anteriores. Os padrões demográficos identificados realçam a necessidade de desenvolver medidas de prevenção específicas para os diferentes grupos.

BACKGROUND AND AIMS: Increasing demand for inpatient endoscopic services results in performing more non-emergent endoscopic cases after-hours, which poses risks to patient safety and negatively impacts patient and provider satisfaction. This study sought to quantify the existing state using quality improvement (QI) methodology, design targeted interventions, and determine their effectiveness. METHODS: We conducted an existing state evaluation through a process map, time-series study, and caseload analysis from 7/2017-12/2018. Using end-of-workday (EOW) as a proxy for patient/provider dissatisfaction and risk for patient safety events, we performed a prospective evaluation of a staged interdisciplinary multimodal intervention aimed to decrease the proportion of days with EOW after 7PM, decrease the proportion of cases begun after 5PM, and decrease EOW variability. The post-intervention period was 6/2019-2/2020. RESULTS: Based on existing state analyses, we implemented a series of targeted interventions: (1) provider workflow tips, (2) expedited transport for select patients, (3) pathway to reschedule appropriate cases to outpatient endoscopy, and (4) increased staffing for high caseload days through resource pooling. The proportion of days with EOW after 7PM decreased from 42.4% to 29.3% (caseload-adjusted odds ratio of 0.39, p< 0.001). Despite increased caseload, cases begun after 5PM decreased from 17.5% to 14.2% (OR 0.75, p = 0.009). EOW SD decreased from 2:20 hours to 1:36 hours. CONCLUSIONS: The multimodal intervention reduced days with EOW after 7PM and the proportion of cases begun after 5PM, despite increased caseload. This study shows how applying research methods to implement QI interventions successfully decreases late inpatient endoscopic cases.
RESUMEN
PURPOSE: The United States of America has the highest gun ownership rate of all high-income nations, and firearms have been identified as a leading cause of ocular trauma and visual impairment. The purpose of this study was to characterize firearm-associated ocular injury and identify at-risk groups. METHODS: Patients admitted with firearm-associated ocular injury were identified from the National Trauma Data Bank (2008-2014) using the International Classification of Diseases, Ninth Revision, Clinical Modification diagnostic codes and E-codes for external causes. Statistical analysis was performed using the SPSS 24 software. Significance was set at p<0.05. RESULTS: Of the 235,254 patients, 8,715 (3.7%) admitted with firearm-associated trauma had ocular injuries. Mean (standard deviation) age was 33.8 (16.9) years. Most were males (85.7%), White (46.6%), and from the South (42.9%). Black patients comprised 35% of cases. Common injuries were orbital fractures (38.6%) and open globe injuries (34.7%). Frequent locations of injury were at home (43.8%) and on the street (21.4%). Black patients had the highest risk of experiencing assault (odds ratio [OR]: 9.0; 95% confidence interval [CI]: 8.02-10.11; p<0.001) and street location of injury (OR: 3.05; 95% CI: 2.74-3.39; p<0.001), while White patients had the highest risk of self--inflicted injury (OR: 10.53; 95% CI: 9.39-11.81; p<0.001) and home location of injury (OR: 3.64; 95% CI: 3.33-3.98; p<0.001). There was a steadily increasing risk of self-inflicted injuries with age peaking in those >80 years (OR: 12.01; 95% CI: 7.49-19.23; p<0.001). Mean (standard deviation) Glasgow Coma Scale and injury severity scores were 10 (5.5) and 18.6 (13.0), respectively. Most injuries (53.1%) were classified as severe or very severe injury, 64.6% had traumatic brain injury, and mortality occurred in 16% of cases. CONCLUSION: Most firearm-associated ocular injuries occurred in young, male, White, and Southern patients. Blacks were disproportionally affected. Most firearm-associated ocular injuries were sight--threatening and associated with traumatic brain injury. The majority survived, with potential long-term disabilities. The demographic differences identified in this study may represent potential targets for prevention.

RESUMO Objetivo: Os Estados Unidos têm a maior taxa de posse de armas de fogo de todos os países de alta renda e essas armas foram identificados como uma das maiores causas de trauma ocular e deficiência visual. O objetivo deste estudo foi caracterizar as lesões oculares associadas a armas de fogo e identificar grupos de risco. Métodos: Foram identificados pacientes hospitalizados com lesões oculares associadas a armas de fogo no período de 2008 a 2014, a partir do Banco de Dados Nacional de Trauma (National Trauma Data Bank), usando os códigos de diagnósticos da CID9MC e códigos "E" para causas externas. A análise estatística foi efetuada usando o programa SPSS. O nível de significância considerado foi de p<0,05. Resultados: De um total de 235.254 pacientes hospitalizados com trauma associado a armas de fogo, 8.715 (3,7%) tinham lesões oculares. A média de idade foi de 33,8 (DP 16,9) anos. A maioria foi de homens (85,7%), brancos (46,6%) e da região Sul (42,9%); 35% dos pacientes eram negros. As lesões mais comuns foram fraturas de órbita (38,6%) e lesões de globo aberto (34,7%). Os locais mais frequentes foram a residência (43,8%) e a rua (21,4%). Pacientes negros tiveram maior probabilidade de sofrer agressões (RP=9,0, IC 95%=8,02-10,11; p<0,001) e da ocorrência ser na rua (RP=3,05, IC 95%=2,74-3,39; p<0,001), enquanto pacientes brancos tiveram maior probabilidade de lesões autoprovocadas (RP=10,53, IC 95%=9,39-11,81; p<0,001) e da ocorrência ser na residência (RP=3,64, IC 95%=3,33-3,98; p<0,001). A probabilidade de lesões autoprovocadas aumentou com a idade de forma consistente, atingindo o máximo em pacientes com mais de 80 anos (RP=12,01, IC 95%=7,49-19,23; p<0,001). A pontuação média na escala de coma de Glasgow foi 10 (DP 5,5) e na escala de severidade da lesão foi 18,6 (DP 13,0). A maioria das lesões (53,1%) foi classificada como severa ou muito severa. Dentre os pacientes, 64,6% tiveram lesão cerebral traumática e 16% evoluíram a óbito. Conclusão: A maior parte das lesões oculares relacionadas a armas de fogo ocorreu em pacientes jovens, do sexo masculino, brancos e sulistas. Negros foram afetados desproporcionalmente. A maior parte das lesões oculares relacionadas a armas de fogo apresentou riscos à visão e foi associada a lesões cerebrais traumáticas. A maioria dos pacientes sobreviveu, mas com potencial para invalidez no longo prazo. As diferenças demográficas identificadas podem ser potencialmente alvos de ações preventivas.
