Le taux de survie des patients souffrant d’un arrêt cardiaque extrahospitalier est inférieur à 10% même avec les meilleures pratiques en réanimation. Une nouvelle technique de réanimation, soit la réanimation par circulation extracorporelle, a été mise à l’essai et s’avère prometteuse pour améliorer le pronostic chez cette population. Par contre, des réponses à plusieurs enjeux doivent être obtenues avant de tester de façon prospective les avantages de cette technique, notamment quant aux impacts collatéraux sur les pratiques de réanimation préhospitalière qu’elle impliquerait, à la sélection des patients et aux potentielles stratégies de monitorage à utiliser chez ces patients. Cette thèse vise à répondre à ces questions avant d’éventuellement démontrer la valeur ajoutée de cette technique de réanimation et ainsi améliorer la survie pour ces patients. Le premier volet présente les résultats de trois études de cohorte explorant les impacts qu’aurait l’incorporation de la réanimation par circulation extracorporelle sur les protocoles de soins. Les résultats d’une première étude de cohorte ont démontré que la durée des manœuvres de réanimation avancées pratiquées en préhospitalier pourrait être réduite pour permettre un départ plus rapide vers un centre hospitalier pouvant initier la réanimation par circulation extracorporelle puisqu’il n’y avait pas d’association positive entre la durée de ces manœuvres et la survie chez ces patients. Les résultats d’une deuxième étude ont démontré que de rediriger les patients en arrêt cardiaque vers les centres hospitaliers pouvant pratiquer la réanimation par circulation extracorporelle pourrait augmenter leur taux de survie. Ce bénéfice potentiel subsistait jusqu’à un ajout de 14 minutes de la durée du trajet par ambulance dû à la redirection. Troisièmement, la modification de ces deux protocoles de soins permettrait à potentiellement trois fois plus de patients de bénéficier d’une réanimation par circulation extracorporelle. Le second volet présente les résultats de deux études visant à optimiser la sélection des patients pour une réanimation par circulation extracorporelle. Les résultats d’une première étude de cohorte descriptive ont démontré que les patients nécessitant plus de 10 défibrillations conservaient un pronostic de survie adéquat, et ainsi devraient demeurer éligible à une réanimation par circulation extracorporelle. Dans une deuxième étude de cohorte, nous avons étudié l’impact pronostique d’une conversion de rythme pendant la réanimation et avons démontré que le rythme initial était un meilleur marqueur de pronostic que la conversion du rythme. Ainsi, les patients ayant une conversion d’un rythme non-défibrillable à un rythme défibrillable ne devraient pas être retenus en première intention pour une réanimation par circulation extracorporelle, contrairement à ceux dont le rythme initial était déjà défibrillable. Les études du troisième volet visaient à explorer l’usage d’une technologie de monitorage de l’oxymétrie tissulaire, la spectroscopie proche-infrarouge, en raison de son potentiel pour mesurer en continu le degré d’oxygénation des candidats à une réanimation par circulation extracorporelle. Une revue systématique de la littérature a démontré l’utilité pronostique de cette technologie pour les patients en arrêt cardiaque. Ensuite, nous avons décrit à l’aide d’une cohorte prospective les propriétés métrologiques de deux appareils et les facteurs associés permettant d’optimiser leur utilité dans le contexte de patients en arrêt cardiaque. Les connaissances développées par l’entremise des études composant la présente thèse ont déjà été intégrées aux protocoles de prise en charge des patients souffrant d’un arrêt cardiaque extrahospitalier ce qui jette des bases solides pour poursuivre des recherches pour ultimement améliorer leur pronostic. / Despite advances in medical care, survival amongst out of hospital cardiac arrest patients remains low, with only 10% of patients surviving. The use of extracorporeal cardiopulmonary resuscitation, a novel resuscitation procedure, has recently garnered interest and showed promise to improve resuscitation outcomes. However, questions remain to be answered before this technology can be prospectively evaluated, notably regarding the collateral impacts of its implementation, appropriate patient selection and the monitoring strategies to use for these patients. The main objective of this thesis is to answer these questions to eventually improve the outcome of patients suffering from an out-of-hospital cardiac arrest. In the first part, the results of three cohort studies exploring the potential impact of the implementation of extracorporeal resuscitation on prehospital resuscitation protocols are presented. A first cohort study showed that the duration of prehospital advanced cardiac life support could be reduced to allow for an earlier transport to an extracorporeal resuscitation centre. A second cohort study showed that patients being transported to specialized resuscitation centres might have increased survival. This increase in survival would remain despite an additional 14 minutes of prehospital transport time due to the redirection. A third study showed that prehospital redirection could triple the number of patients who could benefit from extracorporeal resuscitation. In the second part, the results of two studies aiming to improve the selection of adequate patients for extracorporeal resuscitation are presented. A first cohort study showed that patients requiring more than 10 defibrillations still had an adequate chance at survival and should remain eligible for an extracorporeal resuscitation. A second cohort study showed that the initial rhythm was a much better prognosticating factor than subsequent rhythms. Patients with an initial non- shockable rhythm who experience a conversion to a shockable rhythm should not be considered first-line candidates for extracorporeal resuscitation. In the third part, three studies exploring the potential uses of near-infrared spectroscopy for the monitoring of extracorporeal resuscitation patients are presented. A systematic review was first performed and showed the prognosticating ability of this technology for patients suffering from a cardiac arrest. Then, using a prospective cohort, the metrological properties and their determinants of two frequently used near-infrared spectroscopy devices were described, in order to optimize their uses in the context of cardiac arrest. The knowledge acquired by the studies comprised in this thesis has already been integrated in protocols guiding the care for patients suffering from an out-of-hospital cardiac arrest and has laid the foundation for the prospective evaluation of extracorporeal resuscitation for this population, which will hopefully ultimately lead to improvement in their prognosis.

This thesis engages in its theoretical part description of the process of pursuance and assurance of quality in emergency medical dispatch centre. There is also a comprehensive description of key quality parameters used in this environment in this part. The content of the empiric section is an organizational case study, which aim was to evaluate an extensive organizational change in emergency medical dispatch centre of the Emergency Medical Service of the Central Bohemian region and its impacts on the quality of care. The first phase of centralization of emergency medical dispatch centres in the Central Bohemian region went through during the first half of 2011. Four local emergency medical dispatch centres were gradually brought together into one entity. The aim of the research was to evaluate impacts of the organizational change on key quality parameters. The observational retrospective study consists of two groups of data, collected from identical area during two equivalent periods. Group A contains data from the period of six months before and group B contains data from the period of six months after the centralization. Key quality indicators were compared in both groups: response time; call processing times; safety of classification and indication of calls; use of dispatch life support and...

Triage assessment of patients on arrival at the emergency unit is an essential function in quality emergency care provision. Triage is the process of sorting and prioritising patients according to their level of acuity. This study was performed within an emergency unit that experienced serious problems with the sorting of patients on their arrival. After implementation of the Cape Triage Score, a questionnaire was distributed amongst staff utilising the new triage system. The investigation sought to answer specific questions concerning the triage nurse's roles, competencies required and strengths and weaknesses of the implemented system. The study also suggests guidelines to improve the triage system within the unit. The triage system was received well by participants. The roles of the triage nurse are multifaceted and extensive competencies are required. The strengths of the implemented triage system outweighed the weaknesses as perceived by the respondents. Guidelines for implementing triage in emergency units are provided. / Health Studies / M.A. (Health Studies)

Serious illness in childhood is a rare occurrence, but accounts for 20% of childhood deaths. Early recognition and treatment of serious illness is vital if the child is to recover without long-term disability. It is known that vital signs such as heart rate, respiratory rate, temperature, and oxygen saturation can be used to identify children who are at high risk of serious illness. This thesis presents research into the development of a vital signs monitor, designed for use in the initial assessment of unwell children at their first point of contact with a medical practitioner. Child-friendly monitoring techniques are used to obtain vital signs, which can then be combined using data fusion techniques to assist clinicians in identifying children with serious illness. Existing normal ranges for heart rate and respiratory rate in childhood vary considerably, and do not appear to be based on clinical evidence. This thesis presents a systematic meta-analysis of heart rate and respiratory rate from birth to 18 years of age, providing evidence-based curves which can be used to assess the degree of abnormality in these important vital signs. Respiratory rate is particularly difficult to measure in children, but is known to be predictive of serious illness. Current methods of automated measurement can be distressing, or are time-consuming to apply. This thesis therefore presents a novel method for estimating the respiratory rate from an optical finger sensor, the pulse oximeter, which is routinely used in clinical practice. Information from multiple vital signs can be used to identify children at risk of serious illness. A number of data fusion techniques were tested on data collected from children attending primary and emergency care, and shown to outperform equivalent existing scoring systems when used to identify those with more serious illness.

Objetivo: comparar o perfil lipídico de em crianças e adolescentes, com e sem inflamação, atendidas num pronto atendimento geral de pediatria de um hospital universitário de nível de atendimento secundário, segundo estado nutricional, sexo e idade. Métodos: Estudo transversal, realizado entre outubro de 2012 e agosto de 2013, avaliou 124 crianças e adolescentes (3 meses a 14 anos de idade) em atendimento na unidade de emergência do Hospital Universitário da Universidade de São Paulo, com queixa relacionada a processo inflamatório/infeccioso. Os pacientes foram separados em dois grupos de acordo com os níveis de proteína C reativa (PCR): grupo I se maior ou igual a 5 mg/L, e grupo II se menor que 5mg/L. Dosagens de colesterol total, lipoproteína de alta densidade (HDL) e baixa densidade (LDL), triglicerídeos e albumina foram comparadas entre os dois grupos, levando em conta o estado nutricional (avaliado através de medidas antropométricas), gênero e idade. Resultado: A mediana de idade foi de 51 meses, com maioria dos pacientes classificados como eutróficos (76,5%). Do total da amostra, 34,7% dos pacientes apresentaram colesterol total e/ou triglicerídeos alterados e 67% apresentaram baixos níveis de HDL. Não houve diferença significativa do perfil lipídico entre os dois grupos de pacientes separados de acordo com PCR. Dentre os pacientes com PCR >= 5mg/L, a PCR apresentou correlação inversa com HDL [r= (-)0,363 e p=0,001], com LDL [r= (-) 0,235 e p=0,034], com albumina [r= (-) 0,308 e p=0,005] e correlação direta com TG (r=0,426 e p > 0,001). Na analise de regressão linear, se evidenciou que para cada aumento de 1mg/L nos valores da PCR espera-se uma redução média de 0,072 mg/dL da HDL, de 0,083 mg/dL da LDL, de 0,002g/dL de albumina, e um aumento médio de 0,564 mg/dL do triglicerídeo. Conclusão: Pacientes com processo inflamatório apresentam alterações nos níveis séricos do HDL, LDL e triglicerídeos que se relacionam com o grau de inflamação, de forma independente do estado nutricional / Aim: To compare the lipid profile in children and adolescents with and without inflammation, met a ready general pediatric service of a university hospital secondary care level, according to nutritional status, gender and age. Methods: Cross-sectional study conducted between October 2012 and August 2013, assessed 124 children and adolescents (3 months to 14 years old) in the emergency department of the University Hospital of the University of São Paulo, with reports of inflammatory/ infectious process. The patients were divided into two groups according to the C reactive protein (CRP) levels: group I is higher than or equal to 5 mg/L, and Group II was lower than 5 mg/L. Total cholesterol, high density lipoprotein (HDL) and low density lipoprotein (LDL), triglycerides and albumin were compared between the two groups, taking into account the nutritional status (assessed by anthropometric measurements), gender and age. Results: The median age was 51 months, with patients mostly classified as well-nourished (76.5%). Of the overall sample, 34.7% of patients had total cholesterol and/or triglycerides altered and 67% had low levels of HDL. There was no significant difference in lipid profile between the two groups of PCR. For the patients with CPR > 5mg/L, CPR presented an inverse correlation with HDL [r = (-) 0.363 and p = 0.001], with LDL [r = (-) 0.235 and p = 0.034], with [r = albumin (-) 0.308 and p = 0.005] and direct correlation with TG (r = 0.426 and p < 0.001). Linear regression analysis it became clear that for each increase of 1 mg/L in the values of CRP expected an average reduction of 0,072 mg/dL of HDL, the 0,083 mg/dL of LDL, the 0,002 g /dL albumin, and an average increase of 0,564 mg/dL of triglycerides. Conclusion: Patients with an inflammatory process exhibit changes in the serum levels of the lipids HDL, LDL and TG that are related to the degree of inflammation. These changes occurred regardless of nutritional status

Introdução: Ainda que o uso de Sondas Nasoentéricas (SNE) pareça ser frequente em hospitais, são raros os estudos dimensionando a prevalência do procedimento e o tempo despendido entre indicação e seu uso, especialmente em Emergências. Nestes espaços assistenciais, os atrasos podem contribuir para a manutenção da superlotação e, também, configurarem-se como incidentes no processo assistencial. Objetivo: Conhecer o tempo entre a indicação da SNE e seu efetivo uso e entre as etapas intermediárias desse processo, além de dos fatores associados a atrasos. Método: Entre abril e junho de 2015, foram incluídos adultos admitidos em uma Emergência de um hospital universitário brasileiro em uma coorte prospectiva. Os pacientes foram acompanhados do momento da indicação ao efetivo uso da SNE, mesurando-se os tempos demandados em cada etapa e os possíveis fatores associados ao tempo despendido até a utilização da sonda (variáveis relacionadas à clínica do paciente ou ao processo de trabalho). Para avaliar os fatores associados a ao tempo despendido, adotou-se o modelo de Equações de Estimações Generalizadas (Generalized Estimating Equations – GEE), respeitando-se a distribuição Gamma da variável diferença de tempo. Para a comparação intrafatores foi adotado o teste de Bonferroni como teste Post Hoc. Resultados: Houve 150 inserções de SNE em 115 pacientes. A mediana de tempo entre a indicação e o uso da sonda foi 573 (IQR: 360 - 1093; mínimo: 63 – máximo: 3120) minutos. Analisando-se as diferentes subetapas do processo, foram identificados como fatores independentes de risco para maior tempo entre a indicação e o uso da SNE: inserção de SNE em paciente que não a utilizava antes do atendimento na Emergência, médico não entregar a prescrição de inserção de sonda ao enfermeiro, inserção de SNE na jornada de trabalho noturna, alocação do paciente na sala de cuidados intensivos, retardos na rotina médica, da nutrição e de enfermagem, uso de ventilação mecânica, noradrenalina e necessidade de jejum. Conclusão: O tempo entre a indicação e o uso de sonda nasoentérica foi elevado, excedendo 10 horas em metade dos casos. Fatores relacionados às condições clínicas dos pacientes e à gestão da assistência contribuiriam para o aumento neste tempo. / Background: Although the use of Nasoenteric tubes (NET) appears to be common in hospitals, few studies measure the prevalence of the procedure and the time between the indication and its use, especially in Emergencie Departement. In the Emergency Departament, delays may contribute to the maintenance of overcrowding and also being configured as incidents in the care process. Objective: Knowing the time spent between the indication of the NET and its effective use, as well as the times and factors associated to delays in sub-steps of process. Method: Between April and June 2015, patients adults admitted to an Emergency Departament of a Brazilian university hospital were included in a prospective Cohort. Patients were followed-up from the NET indication until its effective use. The spent time in each sub-step and the possible associated factors with the time taken to use the NET (variables related to the patient's clinical or work process) were analised. To evaluate the associated factors with time spent, the Generalized Estimating Equations model was adopted, respecting the Gamma distribution of variable "time difference". For intrafatores comparison was adopted Bonferroni test as a post hoc test. Results: There were 150 insertions NET in 115 patients. The median time between the NET indication and its use was 573 (IQR: 360-1093; minimum: 63 - maximum: 3120) minutes. Analyzing the different sub-steps of the process, were identified as independent risk factors for increased time between the NET indication and its use: NET insertion in patients who do not used before the Emergency Departement, doctor does not deliver the NET insert prescription to the nurse, NET insertion in the night working hours, patient allocation in intensive care room, delays in medical, nutrition and nursing routine, patients undergoing mechanical ventilation, norepinephrine and need fasting. Conclusion: The time between the NET indication and its use was high, exceeding 10 hours in half the cases. Factors related to the patients' clinical conditions and the management of the assistance would contribute to the increase at this time lapse. / Introducción: Aunque el usio de Sondas Nasoentericas (SNE) parezca frequenteen Hospitales, son raros los estudios dimensionando el predominio el procedimiento y el tiempo dispensado entre indicación y el uso, especialmente em Emergencias.

Factores relacionados a lãs condiciones clinicas de los pacientes y de la gestion de la Asistencia contribuyeron para el aumento en este tiempo.

<p>Тешка траума се може дефинисати на неколико различитих начина. Најчешће коришћена дефиниција укључује коришћење Injury Severity Score ( ISS скор). Ако је вредност ISS скор &gt;15, ради се о тешкој трауми. Траума је временски осетљиво стање, због тога је за збрињавање тешко повређених пацијената неопходна добра сарадња различитих нивоа здравствене заштите и здравствених стручњака различитих специјалности. У претходних неколико деценија, због сложенијег процеса лечења и великих трошкова, дошло је до потребе за што објективнијом проценом стања повређеног и исхода лечења. Циљ: Упоредити сензитивност и специфичност T-RTS скорa (Triage Revised Trauma Score), CRAMS скалe (Circulation, Respiration, Abdomen, Motor and Speech), МGAP скора (Mechanism, Glasgow coma scale, Age, and arterial Pressure) и GAP скора (Glasgow coma scale, Age, and arterial Pressure) примењених на прехоспиталном нивоу, проценити могућности прехоспитално примењених RTS, CRAMS, МGAP и GAP скорова у предикцији исхода лечења повређеног пацијента и утврдити значај појединачних фактора, одређиваних на прехоспиталном нивоу током иницијалног прегледa повређеног, за процену тежине повреде и предикцију исхода лечења повређеног. Истраживање је проспективног, опсервационог карактера. У истраживање су укључени пацијенти старији од 18 година, које су лекари Заводa за хитну медицинску помоћ Нови Сад (ЗЗХМП НС) и Службe хитне медицинске помоћи Дома здравља Бечеј (СХМП ДЗ Бечеј) збрињавали на терену након трауме, а потом их транспортовали у Ургентни центар Клиничког центра Војводине (УЦ КЦВ). На основу вредности ISS скора пацијенти су сврстани у једну од две групе: група А- пацијенти код којих је ISS скор након завршене дијагностике изнад 15- тешка траума и група Б -пацијенти код којих је након завршене дијагностике ISS скор &le;15- лака траума. У групи А је било 50, а у групи Б 257 пацијената. За граничне вредности скорова које означавају да траума није лака, највећу сензитивност у оцени тежине трауме је имао GAP скор 98,8%, а највећу специфичност MGAP скор 62%. У предвиђању исхода лечења, највећу сензитивност је имао RTS скор за предикцију 95,2%, а специфичност GAP скор и CRAMS скала 87,5%. MGAP скор, а пошто је у снажној корелацији са њим и GAP скор, мерени прехоспитално, су се издвојили као независни предиктор у оцени тежине трауме и предвиђању исхода лечења повређеног. Т- RTS скор и CRAMS скала су се издвојили као појединачни предиктори у оцени тежине трауме, али не и као независни предиктори. RTS скор за предикцију нема статистичку значајност у предвиђању исхода лечења повређеног, за разлику од CRAMS скале која има, али се није издвојила као независни предиктор исхода лечења. Осим наведених траума скорова, као независни предиктори у оцени тежине трауме издвојили су се: систолни крвни притисак, SaO2 у периферној крви мерена пулсном оксиметријом, повреда главе и врата и повреда грудног коша. За предвиђање исхода лечења повређеног само се SaO2 у периферној крви мерена пулсном оксиметријом издвојила као појединачни предиктор, али не и као независни предиктор исхода.</p> / <p>Teška trauma se može definisati na nekoliko različitih načina. Najčešće korišćena definicija uključuje korišćenje Injury Severity Score ( ISS skor). Ako je vrednost ISS skor &gt;15, radi se o teškoj traumi. Trauma je vremenski osetljivo stanje, zbog toga je za zbrinjavanje teško povređenih pacijenata neophodna dobra saradnja različitih nivoa zdravstvene zaštite i zdravstvenih stručnjaka različitih specijalnosti. U prethodnih nekoliko decenija, zbog složenijeg procesa lečenja i velikih troškova, došlo je do potrebe za što objektivnijom procenom stanja povređenog i ishoda lečenja. Cilj: Uporediti senzitivnost i specifičnost T-RTS skora (Triage Revised Trauma Score), CRAMS skale (Circulation, Respiration, Abdomen, Motor and Speech), MGAP skora (Mechanism, Glasgow coma scale, Age, and arterial Pressure) i GAP skora (Glasgow coma scale, Age, and arterial Pressure) primenjenih na prehospitalnom nivou, proceniti mogućnosti prehospitalno primenjenih RTS, CRAMS, MGAP i GAP skorova u predikciji ishoda lečenja povređenog pacijenta i utvrditi značaj pojedinačnih faktora, određivanih na prehospitalnom nivou tokom inicijalnog pregleda povređenog, za procenu težine povrede i predikciju ishoda lečenja povređenog. Istraživanje je prospektivnog, opservacionog karaktera. U istraživanje su uključeni pacijenti stariji od 18 godina, koje su lekari Zavoda za hitnu medicinsku pomoć Novi Sad (ZZHMP NS) i Službe hitne medicinske pomoći Doma zdravlja Bečej (SHMP DZ Bečej) zbrinjavali na terenu nakon traume, a potom ih transportovali u Urgentni centar Kliničkog centra Vojvodine (UC KCV). Na osnovu vrednosti ISS skora pacijenti su svrstani u jednu od dve grupe: grupa A- pacijenti kod kojih je ISS skor nakon završene dijagnostike iznad 15- teška trauma i grupa B -pacijenti kod kojih je nakon završene dijagnostike ISS skor &le;15- laka trauma. U grupi A je bilo 50, a u grupi B 257 pacijenata. Za granične vrednosti skorova koje označavaju da trauma nije laka, najveću senzitivnost u oceni težine traume je imao GAP skor 98,8%, a najveću specifičnost MGAP skor 62%. U predviđanju ishoda lečenja, najveću senzitivnost je imao RTS skor za predikciju 95,2%, a specifičnost GAP skor i CRAMS skala 87,5%. MGAP skor, a pošto je u snažnoj korelaciji sa njim i GAP skor, mereni prehospitalno, su se izdvojili kao nezavisni prediktor u oceni težine traume i predviđanju ishoda lečenja povređenog. T- RTS skor i CRAMS skala su se izdvojili kao pojedinačni prediktori u oceni težine traume, ali ne i kao nezavisni prediktori. RTS skor za predikciju nema statističku značajnost u predviđanju ishoda lečenja povređenog, za razliku od CRAMS skale koja ima, ali se nije izdvojila kao nezavisni prediktor ishoda lečenja. Osim navedenih trauma skorova, kao nezavisni prediktori u oceni težine traume izdvojili su se: sistolni krvni pritisak, SaO2 u perifernoj krvi merena pulsnom oksimetrijom, povreda glave i vrata i povreda grudnog koša. Za predviđanje ishoda lečenja povređenog samo se SaO2 u perifernoj krvi merena pulsnom oksimetrijom izdvojila kao pojedinačni prediktor, ali ne i kao nezavisni prediktor ishoda.</p> / <p>Severe trauma could be defined in several ways. The most commonly used definition includes Injury Severity Score (ISS) and severe trauma is determined if ISS &gt;15. Trauma management is a time sensitive issue and a coordination between different levels of health system and many specialists is vital in the treatment of severe trauma. In the last decades, a need for the objective evaluation of the severity of trauma and its outcome was perceived due to the complex management and treatment of trauma and its costs. Aim of the study: to compare the sensitivity and specificity between prehospital scores T-RTS (Revised Trauma Score), CRAMS (Circulation, Respiration, Abdomen, Motors, Speech), MGAP (Mechanism, Glasgow Coma Scale, Age, Arterial Pressure) and GAP (Glasgow Coma Scale, Age, Arterial Pressure), to assess the predictability of prehospital scores (RTS, CRAMS, MGAP and GAP) in the outcome of traumatized patients, to determine the significance of individual factors, initially determined during the prehospital evaluation, in evaluating the severity of trauma and the outcome of treatment. Patients enrolled into this prospective observational study were older than 18, prehospitally treated on the trauma site by the doctors of the Institute of the Emergency Medicine Novi Sad and Health Centre Bečej &ndash; Emergency Medical Service and afterward transported into the Emergency Centre Novi Sad. Based on ISS values, patients were divided into two groups: Group A &ndash; severe trauma (50 patients; ISS&gt;15) and Group B &ndash; mild trauma (257 patients; ISS&le;15). For the broder values of scores, determining the severity of trauma, GAP had the highest sensitivity (98%), while MGAP had the highest specificity (62%). RTS had the highest sensitivity in predicting the outcome (95.2%), while GAP and CRAMS had specificity of 87.5%. Prehospital MGAP score, in strong correlation with GAP, was singled out for its independent predictive value in determining the severity of trauma and its outcome. T-RTS and CRAMS stood out to be individual &ndash; but not independent &ndash; predictors in evaluating the severity of trauma. RTS was not statistically significant in predicting the outcome, in contrast with CRAMS. However, CRAMS was not singled out as an independent predictor of the outcome. In addition to the scores, independent predictors of the severity of trauma were: systolic blood pressure, arterial oxygen saturation (SaO2) by using the pulse oximeter, head, neck and thorax injuries. Only SaO2 proved to be a single &ndash; but not independent &ndash; predictor of the outcome.</p>

O trauma é uma das principais causas de morte no mundo. Estima-se que mais de cinco milhões de pessoas morrem anualmente por algum tipo de trauma e que outras milhões que sobrevivem aos ferimentos ficam com sequelas temporárias ou permanentes, o que implica em custos diretos e indiretos de bilhões de reais. Desta forma, o problema do trauma envolve questões de ordem epidemiológica, social, assistencial, financeira e de gestão. Uma das maneiras de minimizar este problema é avaliar as fases do atendimento por meio de programas de melhoria de qualidade. O Comitê de Trauma do Colégio Americano de Cirurgiões criou uma base de dados única de registros de traumas de diversos centros nos Estados Unidos e Canadá na base de dados única do National Trauma Data Bank (NTDB). Após coletados, os dados são processados e transformados em relatórios anuais com indicadores que fornecem uma visão da situação geral do atendimento ao trauma em todo o país. Muitos países investem recursos para construir registros de trauma ou base de dados regionais, que são importantes fontes de dados para construção de indicadores de qualidade. No Brasil não existe a notificação sistemática dos pacientes traumatizados nos serviços de saúde. O presente estudo tem por finalidade desenvolver um software com módulo de notificação e vigilância epidemiológica dos traumas associado à monitorização e análise dos dados consolidados utilizando indicadores de qualidade. Para teste do software foi utilizado o banco de dados de pacientes traumatizados atendidos na Unidade de Emergência do Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto - Universidade de São Paulo (UE-HCFMRP/USP) no período de 2006 a 2014. No software desenvolvido há duas maneiras de inserir dados de trauma: manualmente por meio do preenchimento do formulário eletrônico de notificação ou por meio da importação direta de arquivo Excel com a mesma sequência de dados. Desta forma, os indicadores são gerados automaticamente e podem ser visualizados em gráficos e tabelas. Os resultados obtidos através do uso da ferramenta foram utilizados para analisar a situação da assistência ao trauma na região de Ribeirão Preto. A análise destes resultados também foi essencial para verificar a capacidade da ferramenta em prover informações relevantes para a gestão hospitalar. A partir da análise dos resultados obtidos, concluímos que a ferramenta pode auxiliar a avaliação da qualidade do atendimento ao trauma. Uma possibilidade de expansão do sistema é incluir novos indicadores e coletar dados de outras instituições para permitir benchmarking externo. / Trauma is a leading cause of death worldwide. It is estimated that more than five million people die annually from some sort of trauma and millions more who survive their injuries are left with temporary or permanent sequelae, which leads to billions of Reais in direct and indirect costs. Thus, the question of trauma involves epidemiological, social, healthcare, financial and management issues. One way to lessen such problems is to evaluate the phases of medical care through quality improvement programs. The American College of Surgeons Committee on Trauma has created a unique aggregation of trauma registry data from several centers in the United States and Canada in a single database, the National Trauma Data Bank (NTDB). After collected, the data are processed into annual reports with indicators that provide a view of the overall situation of trauma care nationwide. Many countries invest resources on gathering trauma registries or building regional databases, which are important sources of data for generating care quality indicators. In Brazil there is no systematic notification of trauma patients in health services. The present study aims to develop a software with a trauma notification and epidemiological surveillance module associated with the monitoring and analysis of the consolidated data using care quality indicators. To test the software we used the database of trauma patients treated at the Emergency Unit of the Clinics Hospital at the Ribeirão Preto Medical School - University of São Paulo (UE HCFMRP/USP) from 2006 to 2014. There are two ways to feed the software with the trauma data: manually, by completing an electronic notification form or by directly importing an Excel file with the same data stream. The indicators are then generated automatically and can be viewed in charts and tables. The results yielded from the software were used to assess the situation of trauma healthcare in the Ribeirão Preto region. The analysis of such results was also crucial to determine the software capacity to provide relevant information for hospital management. The results analysis led us to conclude that the software can help assess the quality of trauma healthcare. A possibility of system expansion is to include new indicators and collect data from other institutions to allow external benchmarking.
