Avaliação dos fatores associados a tromboembolismo pulmonar (TEP), em uma série de autópsias de dez anos / Evaluation on factors associated to pulmonary thromboembolism (PE) in a series of ten years of autopsies

Bricola, Solange Aparecida Petilo de Carvalho 11 December 2009 (has links)
INTRODUÇÃO: A literatura demonstra que tromboembolismo venoso permanece como uma doença subdiagnosticada entre os pacientes hospitalizados, com aproximadamente 25% dos casos associados à internação. OBJETIVOS: Avaliar as doenças associadas ao desenvolvimento de tromboembolismo pulmonar (TEP) diagnosticado em autópsias, e demonstrar a frequência de TEP como causa do óbito ou fator contributivo. MÉTODOS: Estudo caso-controle retrospectivo, realizado no Instituto Central do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, no período de 1995 a 2004. Revisamos os relatórios diagnósticos das autópsias, identificando TEP fatal, quando TEP foi a causa de morte, e TEP não fatal, quando TEP foi doença associada. RESULTADOS: 1.506 pacientes (502 casos e 1.004 controles), 18.359 óbitos no período, média 2.040; 71,2% desses submetidos a autópsias. Observou-se importante declínio nas taxas de autópsias. De 1995-1999 (87,2%) e 2000-2004 (54,4%); p = 0,016. Dos 502 casos (3,8%), em 328 (2,5%) TEP foi causa de morte e 174 (1,3%), causa contributiva. Gênero: 51,6% homens e 48,4% mulheres. Idade: TEP fatal (328) vs controles (1.004), diferença estatisticamente significativa (p = 0,013). Condições prevalentes: câncer grupo, 31,4%, pós-operatório grupo, 17,2%, infecção grupo, 11,7%, e AVC grupo, 11%. Câncer de pulmão, 3,5%, câncer de cérebro e linfoma, 2,8%. Tempo de internação foi utilizado como indicador de imobilização. Outras doenças: AVCH (7,7%), pós-operatório de abdome (6,7%), pneumonia (5,9%), AVCI (3,1%) e pós-operatório vascular (4%) foram frequentes no grupo controle. Em contrapartida, aterosclerose (1,4%), ITU (1,2%), pós-operatório de ginecologia (0,8%), pós-operatório de obstetrícia (0,6%) e doença falciforme (0,6%) foram frequentes no grupo TEP. Cirrose, média de 14,9 dias de internação dos controles vs TEP com 4,4 dias (p < 0,001). Análise multivariada incluiu as condições com p 0,20 da univariada, idade e tempo de internação. Fator protetor para TEP: aneurisma de aorta (OR 0,02, IC 95% 0,46-0,56; p = 0,004), cirrose (OR 0,16, IC 95% 0,08-0,34; p < 0,001) e SIDA (OR 0,44, IC 95% 0,23-0,84; p = 0,013). Entretanto, AVCI (OR 1,82, IC 95% 1,04-3,19; p = 0,035), câncer de cérebro (OR 2,47, IC 95% 1,28-4,78; p = 0,007), câncer indeterminado (OR 3,12, IC 95% 1,01-9,68; p = 0,049), DPOC (OR 2,83, IC 95% 1,47-5,43; p = 0,002), ICC (OR 1,71, IC 95% 1,11-2,62; p = 0,015) e ITU (OR 4,34, IC 95% 1,05-17,82; p = 0,042) mostraram associação positiva com TEP. Idade vs TEP (OR 1,10, IC 95% 1,04-1,16; p = 0,001). Tempo de internação vs TEP (OR 1,19, IC 95% 1,05-1,36; p = 0,008). DISCUSSÃO: A porcentagem dos pacientes com TEP permanece inalterada, ocorrência de 4,1% e 3,4% no primero e no segundo períodos, com uma média de 3,8%. Em 50,4% dos pacientes não foi realizado o diagnóstico clínico de TEP. CONCLUSÃO: Constatou-se AVCI, câncer de cérebro indeterminado, DPOC, ICC e ITU com significância estatística e associação com TEP. Algumas fraquezas do presente estudo devem ser apuradas, e talvez explicarão as discordâncias com a literatura para algumas doenças. A identificação de fatores associados a TEP auxiliarão no diagnóstico precoce / INTRODUCTION: Literature shows that venous thromboembolism (VTE) remains as a sub-diagnostic disease among hospitalized patients, approximately 25% of all cases are associated to hospitalization. PURPOSE: Evaluate diseases associated to pulmonary thromboembolism (PE) development diagnosed in autopsies, and demonstrate the frequency of PE as cause of death or as a contributive factor. METHOD: The reports performed from 1995 to 2004 in a Brazilian tertiary referral medical school we reviewed for a retrospective study the autopsies diagnosis, identified as fatal PE, when PE was the cause of death and nonfatal PE, when PE was an associated disease. RESULTS: 1,506 patients (502 cases and 1004 controls), 18,359 deaths during the period, average 2,040; 71.2% of these were submitted to autopsies. It was observed an important decline in the autopsies rates. From 1995-1999 (87.2%) and 2000-2004 (54.4%) p = 0.016. From 502 cases (3.8%), 328 (2.5%) PE was the cause of death and 174 (1.3%) PE was contributive cause. Gender: 51.6% males and 48.4% females. AGE: fatal PE (328) vs controls (1,004) significant statistic difference (p = 0.013). Prevalent Conditions: cancer group, 31.4%, postsurgical group, 17.2%, infectious group, 11.7%, and CVA group, 11%. Pulmonary Cancer, 3.5%, Brain cancer and Lymphoma, 2.8%. Hospitalization period was taken as immobilization indicator. Other diseases: HCVA (7.7%), abdomen postsurgical (6.7%), pneumonia (5.9%), ICVA (3.1%) and vascular postsurgical (4%) were frequent in the control group. On the other hand, atherosclerosis (1.4%), UTI (Urinary Tract Infection) (1.2%), gynecology postsurgical (0.8%), obstetrics postsurgical (0.6%) and sickle cell anemia (0.6%) were frequent in the PE group. Cirrhosis, average of 14.9 hospitalization days of the controls vs PE with 4.4 days (p < 0.001). Logistic regression analysis includes the in univariated analysis with p 0.20, age and the hospitalization period. Protector factor for PE: Aortic aneurysm (OR 0.02, 95% CI 0.46-0.56; p = 0.004), cirrhosis (OR 0.16, 95% CI 0.08-0.34; p < 0.001) and SIDA (OR 0.44, 95% CI 0.23-0.84; p = 0.013). However, ICVA (OR 1.82, 95% CI 1.04-3.19; p = 0.035); brain cancer (OR 2.47, 95% CI 1.28-4.78; p = 0.007); undetermined cancer (OR 3.12, 95% CI 1.01-9.68, p= 0.049), COPD (OR 2.83, 95% CI 1.47-5.43; p = 0.002), CHF (OR 1.71, 95% CI 1.11-2.62; p = 0.015) and UTI (OR 4.34, 95% CI 1.05-17.82; p = 0.042), showed positive association with PE. Age vs PE (OR 1.10, 95% CI 1.04-1.16; p = 0.001). Hospitalization Period vs PE (OR 1.19, 95% CI 1.05-1.36; p = 0.008). DISCUSSION: The percentage of patients with PE remains unchanged, occurrence of 4.1% and 3.4% in the first and second periods, with an average of 3.8%. In 50.4% of the patients, the clinical diagnosis of TEP was not performed. CONCLUSION: We certified ICVA, brain cancer, undetermined cancer, COPD, CHF and UTI with significant association with PE. Some weaknesses of the present study should be refined, and maybe will explain the disagreement with the literature to some diseases. The identification of factors associated to PE will help in precocious diagnosis

Minimizing Risks and Morbidity in Live Kidney Donors

Biglarnia, Ali-Reza January 2010 (has links)
Live kidney donors are healthy volunteers who are exposed to major surgical procedure and physical harms with no direct therapeutic benefits. Efforts to minimize their risks and morbidity are therefore of utmost importance. The current thesis describes studies on donor evaluation, surgical procedure and postoperative management of live kidney donors. The overall purpose is to evaluate and possibly improve routines and treatments in order to reduce risks and the overall morbidity of live kidney donors. In Study I, we evaluated the assessment of kidney function during donor evaluation and found that the accuracy of iohexol glomerular filtration rate (GFR) is compromised by large variations in repeated measurements in presumably healthy donors. We proposed that there is a need for improvement of GFR measurements and that the assessment of predonation kidney function should be more comprehensive, involving GFR, laboratory investigations, functional and morphological examinations and sound clinical judgment. In Study II, we addressed the risk of perioperative venous thromboembolism (VTE) and concluded that expanding the standard screening protocol for VTE to include perioperative venous duplex can potentially decrease the VTE-related morbidity. In studies III and IV, we investigated the impact of hand-assisted retroperitoneoscopic (HARS) nephrectomy on donor safety and perioperative morbidity. The HARS nephrectomy uses the hand-assisted approach, which enables immediate manual compression for hemostasis in case of sudden and severe bleeding. Additionally, the pure retroperitoneal access further increases the safety margin of laparoscopic donor nephrectomy by 1) minimizing the risk of intestinal injury, and 2) exposure of the retroperitoneal nerves, making HARS suitable for continuous infusion of local anesthetics (CILA). CILA effectively reduces the need for opioid consumption and has the potential to totally obviate opiate analgesics postoperatively. Consequently, CILA in combination with HARS reduces morphine-related morbidity and promotes postoperative recovery. In accordance with these data, we recommend improvement and modification of the donor evaluation process as well as a broad introduction of HARS nephrectomy in combination with CILA to increase the safety margin for live kidney donors.

New Therapeutic Approaches in Pulmonary Embolism

Schellong, Sebastian M., Schmidt, Benjamin A. 12 February 2014 (has links) (PDF)
Pulmonary embolism as a part of venous thromboembolic disease has a broad spectrum of clinical presentations from minimal disease to life-threatening right heart failure. Therapy has to be guided by the risk associated with the individual clinical state of the patient. As long as hemodynamics are entirely stable, anticoagulation is given in order to prevent early or late recurrence, thereby allowing for endogeneous thrombolysis and recovery. In hemodynamically instable patients, i.e. patients under cardiopulmonary resuscitation or in shock, there is the need for a rapid reduction of thrombus mass in order to restore right ventricular function. Systemic thrombolysis is the most feasible modality to reduce the thrombus burden of the pulmonary circulation in the short term. For hemodynamically stable patients with right ventricular dysfunction as assessed by echocardiography, there is still some controversy as to whether thrombolysis improves the long-term outcome. At the least, thrombolysis may positively modify the short-term course of acute disease in patients with an extremely low risk of bleeding. When the acute phase has been overcome, secondary prophylaxis with vitamin K antagonists has to be given. The duration of secondary prophylaxis requires an individual assessment of both the risk of recurrence and the risk of bleeding. In the near future, new anticoagulant drugs such as direct thrombin and factor Xa inhibitors will offer new treatment modalities for the acute phase as well as for secondary prophylaxis. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.

The incidence of venous thromboembolism : a prospective, community-based study

Ho, Wai Khoon January 2009 (has links)
Venous thromboembolism (VTE), comprising deep venous thrombosis (DVT) and pulmonary embolism (PE), is a common and preventable cause of morbidity among individuals and hospital in-patient mortality. Further, it imposes a substantial burden upon the community and its health care system and economy. Studies performed in Western societies suggest that the annual incidence of DVT is about 0.8 to 1.2 per 1,000, PE about 0.3 to 0.6 per 1,000, and VTE about 1.0 to 1.8 per 1,000. However, it is not known if these estimates can be generalised to the Australian population because of differences in ethnic composition and other risk factors for VTE among the different populations. In this thesis, I undertook a prospective, community-based cohort study over a 13-month period in 2003 – 2004 to determine the incidence and crude event rate of symptomatic, objectively verified VTE in north-east metropolitan Perth. The study population was broadly representative of the national Australian population in terms of age, sex and ethnic distribution. Cases were identified through multiple overlapping sources. The incidence of DVT, PE and VTE in the community were 0.52 (95% confidence interval, CI: 0.41 – 0.63), 0.31 (95% CI: 0.22 – 0.40) and 0.83 (95% CI: 0.69 – 0.97) per 1000 per year, respectively. The annual incidence of DVT, adjusted to the World Standard population, was 0.35 (95% CI: 0.26 – 0.44) per 1000, PE 0.21 (95% CI: 0.14 – 0.28) per 1000 and VTE 0.57 (95% CI: 0.47 – 0.67) per 1000. The crude event rate for VTE was 0.85 (95% CI: 0.71 – 0.99) per 1000 per year. These findings suggest that the incidence of DVT, PE and VTE are lower than in other Western societies studied. Possible reasons include a lower prevalence of exposure to causal risk factors (genetic and environmental) and incomplete case ascertainment. Knowledge of the local incidence and event rate allows health planners to allocate appropriate resources and evaluate cost-effective preventive measures.

A profilaxia farmacológica foi adequada para 68% dos pacientes. Os pacientes cirúrgicos receberam profilaxia farmacológica com maior frequência em relação aos clínicos (76% vs 60%). Em relação à profilaxia geral, os pacientes cirúrgicos receberam menor taxa de profilaxia adequada em relação aos clínicos (15% vs 64%). Apesar disso, a taxa de sangramento decorrente de profilaxia farmacológica foi maior entre os pacientes clínicos em relação aos cirúrgicos (9% vs 3%). Entretanto, os episódios de sangramento foram considerados como menores e não houve nenhum óbito associado ao evento adverso. Conclusão: O uso de anticoagulantes para fins profiláticos e/ou terapêuticos é o fator significante para tempo de internação em UTI. A profilaxia farmacológica do estudo é de 68%, com taxa maior entre os pacientes cirúrgicos em relação aos clínicos (76% vs 60%); O nível de profilaxia farmacológica do estudo mostra a taxa acima da média nacional de 51%, mas ainda aquém do ideal de 100%. A conscientização dos profissionais de saúde, sobretudo de UTI deve ser reforçada para melhor identificação dos pacientes de risco para TEV. / Introduction: Venous Thromboembolism (VTE) includes deep vein thrombosis (DVT) and pulmonary thromboembolism (PTE) which are diseases with the most common avoidable cause of death especially in critical patients, whether surgical or clinical. Objective: Analyze the level of VTE prophylaxis in patients in the Intensive Care Unit (ICU) due to clinical and surgical conditions. Verify clinical factors associated with the development of VTE in the ICU and reduce the scarcity of studies in the literature that evaluate the practices of VTE prophylaxis in ICUs in Brazil. Methods: an observational cross-sectional study of descriptive character performed through electronic medical records analysis. Patients admitted to the ICU during the period from March 2016 to March 2017 had their risks of venous thromboembolism stratified according to the 9th American College of Chest Physicians (ACCP) Guidelines for VTE Prophylaxis. The adequacy of thromboprophylaxis was determined according to the concordance between the established procedure and the recommended behavior in the guidelines. Results: from the 182 patients analyzed, 60% were female. The mean age was 61.8 ± 18.0 years and 77% of the patients were older than 50 years. The mean age of the surgical patients was significantly higher in comparison with clinicians and the patients of the study (p = 0.046), as well as the length of hospital stay (p = 0.005) and in the ICU (p = 0.010). Pharmacological prophylaxis was adequate for 68% of the patients. Surgical patients received pharmacological prophylaxis more frequently than clinicians (76% vs 60%). Regarding prophylaxis, surgical patients received a lower adequate prophylaxis rate than clinicians (15% vs 64%). Despite this, the bleeding rate due to pharmacological prophylaxis was higher among the clinical patients compared to the surgical ones (9% vs 3%). However, the episodes of bleeding were considered as minor and there were no deaths associated with the adverse event. Conclusion: The use of anticoagulants for prophylactic and/or therapeutic purposes is the significant factor for the length ICU stay. The pharmacological prophylaxis of the study is 68%, with a higher rate among the surgical patients compared to the clinical ones (76% vs 60%); The level of pharmacological prophylaxis in the study shows the rate above the national average of 51%, but still below the ideal of 100%. The awareness of health professionals, especially ICUs, shall be reinforced in order to better identify patients at risk for VTE.

Prevenção de riscos de tromboembolismo venoso: estratégias para redução da morbimortalidade / Risk Prevention of Venous Thromboembolism: strategies to reduce morbidity and mortality

Ronilson Gonçalves Rocha 23 January 2014 (has links)
Estudo prospectivo com abordagem quantitativa envolvendo 3 grupos distintos de sujeitos. Grupo 1 constituído por 56 pacientes avaliados para o risco de tromboembolismo venoso (TEV) em um acompanhamento de 30 meses para verificar os desfechos morte, reinternação e profilaxia de TEV. Grupo 2 constituído por 50 enfermeiros assistenciais que responderam questionários sobre TEV, com o propósito de avaliar seus conhecimentos sobre os riscos e profilaxia dessa doença em pacientes clínicos internados. Grupo 3 constituído por 100 enfermeiros assistenciais que responderam questionários similares aos respondidos pelo grupo 2, antes e após treinamento sobre profilaxia de TEV. O objetivo geral foi verificar o grau de conhecimento de enfermeiros sobre tromboembolismo venoso considerando sua inserção no processo de prevenção de riscos; Os objetivos específicos foram: propor e implantar uma estratégia de treinamento para capacitação de enfermeiros no rastreamento de riscos de TEV em pacientes internados; verificar o impacto do treinamento sobre TEV no conhecimento dos enfermeiros para identificação de fatores de risco dessa doença; descrever os desfechos relacionados à TEV em pacientes internados por mais de 24 horas em um hospital quaternário num seguimento de 30 meses. No grupo 1 identificou-se que o evento TEV apresenta alta mortalidade 63,6% para pacientes que não receberam profilaxia. Identificou-se também que a maioria 89,2% desses sujeitos é acompanhada de seus médicos, 53,6% passaram por reinternações e 28,6% continuam usando alguma profilaxia para TEV. No grupo 2 verificou-se que os profissionais não sabem identificar corretamente os fatores de risco para TEV, havendo grande déficit de conhecimento em relação aos fatores de risco e profilaxia da doença, pois 90% da amostra não consegue apontar mais que 5 fatores de risco para TEV considerando-se 24 fatores contemplados por consensos internacionais, demonstrando um grau de conhecimento insuficiente pela utilização de uma escala intervalar proposta nesse estudo. No grupo 3, assim como identificado no grupo 2, houve similaridade no déficit de conhecimento, pois 100% não conseguiram apontar mais que 4 fatores de risco para a doença. Identificou-se que a realização de um treinamento sobre profilaxia de TEV para esses enfermeiros apresenta alto impacto em relação ao grau de retenção de informações sobre TEV, sendo uma ação facilmente replicável para profissionais de instituições hospitalares. Concluiu-se que o uso de um algoritmo/protocolo de avaliação voltado para rastreamento de riscos de TEV por enfermeiros representa uma ferramenta importante no processo de rastreamento e prevenção dessa doença em pacientes clínicos, como proposto nesse estudo, pois nos resultados demonstrou-se que 97% dos enfermeiros do grupo 3 não conhecem qualquer tipo de protocolo relacionado a prevenção de riscos de TEV. Os sujeitos apresentaram excelente nível de conhecimento sobre meios de profilaxia mecânica, mas identificou-se que a maioria 63% nunca deu orientações sobre a profilaxia enquanto cuidam, reforçando o entendimento de que não estão inseridos no processo de prevenção de riscos de TEV para pacientes internados. A inserção dos enfermeiros nesse processo de identificação de riscos deve ser capaz de reduzir a alta taxa de morbimortalidade e reduzir a incidência dessa doença em unidades hospitalares. / This was a prospective quantitative study involving 3 distinct subject groups. Group 1 consisted of 56 patients evaluated for the risk of venous thromboembolism (VTE) in a 30-month follow-up. The outcomes of interest were death, rehospitalization and VTE prophylaxis. Group 2 consisted of 50 assistential nurses who answered VTE questionnaires with the purpose of evaluating their knowledge regarding risks and prophylaxis of VTE in hospitalized nonsurgical patients. The third group consisted of 100 assistential nurses who answered similar questionnaires, before and after VTE prophylaxis training. The general objective of this study was to verify nurses knowledge degrees about VTE considering their immersion in the process of risk prevention. Specific objectives were: to propose and implement a training strategy to capacitate nurses on VTE risk screening in hospitalized patients; verify the training impact about VTE on their knowledge to correctly identify VTE risk factors; to describe the VTE related outcomes in patients admitted for more than 24 hours in a quaternary hospital during a 30-month follow-up. In group 1, VTE event presented high mortality 63.6% in patients who did not receive prophylaxis. Moreover, many of these subjects 89.2% had been followed up by their physicians, 53.6% had been rehospitalized at some point and 28.6% had been taking VTE prophylaxis. In group 2, it was verified that nursing staff did not know how to correctly identify VTE risk factors, establishing considerable knowledge deficit related to VTE risk factors and prophylaxis. In view of the fact that 90% of the sample could not recognize more than 5 of the 24 risk factors stated by international consensus, it was demonstrated an insufficient knowledge degree according to the interval scale used in this study. In group 3, similarly to group 2, there was knowledge deficit related to VTE, since 100% of the group could not recognize more than 4 risk factors. After a VTE prophylaxis training, it was identified that this training provides high impact on the degree of information retention about VTE by the subjects, and this action is easily replicable in hospital institutions. It was concluded that the use of an evaluation algorithm/protocol about VTE risk screening by nurses could be an important tool to screen and prevent VTE in nonsurgical patients, which was the purpose of this study, given that the results showed that 97% of group 3 did not know any VTE risk prevention protocol. The subjects had excellent knowledge levels about mechanical prophylaxis, but it was identified that most of them 63% never gave orientations about prophylaxis during patient care, emphasizing the understanding that they are not fully engaged in the process of VTE risk prevention in hospitalized patients. The immersion of nurses in the process of identifying VTE risks must be capable of reducing the high VTE incidence and mortality and morbidity rates in hospital unities.

O objetivo geral foi verificar o grau de conhecimento de enfermeiros sobre tromboembolismo venoso considerando sua inserção no processo de prevenção de riscos; Os objetivos específicos foram: propor e implantar uma estratégia de treinamento para capacitação de enfermeiros no rastreamento de riscos de TEV em pacientes internados; verificar o impacto do treinamento sobre TEV no conhecimento dos enfermeiros para identificação de fatores de risco dessa doença; descrever os desfechos relacionados à TEV em pacientes internados por mais de 24 horas em um hospital quaternário num seguimento de 30 meses. No grupo 1 identificou-se que o evento TEV apresenta alta mortalidade 63,6% para pacientes que não receberam profilaxia. Identificou-se também que a maioria 89,2% desses sujeitos é acompanhada de seus médicos, 53,6% passaram por reinternações e 28,6% continuam usando alguma profilaxia para TEV. No grupo 2 verificou-se que os profissionais não sabem identificar corretamente os fatores de risco para TEV, havendo grande déficit de conhecimento em relação aos fatores de risco e profilaxia da doença, pois 90% da amostra não consegue apontar mais que 5 fatores de risco para TEV considerando-se 24 fatores contemplados por consensos internacionais, demonstrando um grau de conhecimento insuficiente pela utilização de uma escala intervalar proposta nesse estudo. No grupo 3, assim como identificado no grupo 2, houve similaridade no déficit de conhecimento, pois 100% não conseguiram apontar mais que 4 fatores de risco para a doença. Identificou-se que a realização de um treinamento sobre profilaxia de TEV para esses enfermeiros apresenta alto impacto em relação ao grau de retenção de informações sobre TEV, sendo uma ação facilmente replicável para profissionais de instituições hospitalares. Concluiu-se que o uso de um algoritmo/protocolo de avaliação voltado para rastreamento de riscos de TEV por enfermeiros representa uma ferramenta importante no processo de rastreamento e prevenção dessa doença em pacientes clínicos, como proposto nesse estudo, pois nos resultados demonstrou-se que 97% dos enfermeiros do grupo 3 não conhecem qualquer tipo de protocolo relacionado a prevenção de riscos de TEV. Os sujeitos apresentaram excelente nível de conhecimento sobre meios de profilaxia mecânica, mas identificou-se que a maioria 63% nunca deu orientações sobre a profilaxia enquanto cuidam, reforçando o entendimento de que não estão inseridos no processo de prevenção de riscos de TEV para pacientes internados. A inserção dos enfermeiros nesse processo de identificação de riscos deve ser capaz de reduzir a alta taxa de morbimortalidade e reduzir a incidência dessa doença em unidades hospitalares. / This was a prospective quantitative study involving 3 distinct subject groups. Group 1 consisted of 56 patients evaluated for the risk of venous thromboembolism (VTE) in a 30-month follow-up. The outcomes of interest were death, rehospitalization and VTE prophylaxis. Group 2 consisted of 50 assistential nurses who answered VTE questionnaires with the purpose of evaluating their knowledge regarding risks and prophylaxis of VTE in hospitalized nonsurgical patients. The third group consisted of 100 assistential nurses who answered similar questionnaires, before and after VTE prophylaxis training. The general objective of this study was to verify nurses knowledge degrees about VTE considering their immersion in the process of risk prevention. Specific objectives were: to propose and implement a training strategy to capacitate nurses on VTE risk screening in hospitalized patients; verify the training impact about VTE on their knowledge to correctly identify VTE risk factors; to describe the VTE related outcomes in patients admitted for more than 24 hours in a quaternary hospital during a 30-month follow-up. In group 1, VTE event presented high mortality 63.6% in patients who did not receive prophylaxis. Moreover, many of these subjects 89.2% had been followed up by their physicians, 53.6% had been rehospitalized at some point and 28.6% had been taking VTE prophylaxis. In group 2, it was verified that nursing staff did not know how to correctly identify VTE risk factors, establishing considerable knowledge deficit related to VTE risk factors and prophylaxis. In view of the fact that 90% of the sample could not recognize more than 5 of the 24 risk factors stated by international consensus, it was demonstrated an insufficient knowledge degree according to the interval scale used in this study. In group 3, similarly to group 2, there was knowledge deficit related to VTE, since 100% of the group could not recognize more than 4 risk factors. After a VTE prophylaxis training, it was identified that this training provides high impact on the degree of information retention about VTE by the subjects, and this action is easily replicable in hospital institutions. It was concluded that the use of an evaluation algorithm/protocol about VTE risk screening by nurses could be an important tool to screen and prevent VTE in nonsurgical patients, which was the purpose of this study, given that the results showed that 97% of group 3 did not know any VTE risk prevention protocol. The subjects had excellent knowledge levels about mechanical prophylaxis, but it was identified that most of them 63% never gave orientations about prophylaxis during patient care, emphasizing the understanding that they are not fully engaged in the process of VTE risk prevention in hospitalized patients. The immersion of nurses in the process of identifying VTE risks must be capable of reducing the high VTE incidence and mortality and morbidity rates in hospital unities.

Avaliação dos fatores associados a tromboembolismo pulmonar (TEP), em uma série de autópsias de dez anos / Evaluation on factors associated to pulmonary thromboembolism (PE) in a series of ten years of autopsies

Solange Aparecida Petilo de Carvalho Bricola 11 December 2009 (has links)
INTRODUÇÃO: A literatura demonstra que tromboembolismo venoso permanece como uma doença subdiagnosticada entre os pacientes hospitalizados, com aproximadamente 25% dos casos associados à internação. OBJETIVOS: Avaliar as doenças associadas ao desenvolvimento de tromboembolismo pulmonar (TEP) diagnosticado em autópsias, e demonstrar a frequência de TEP como causa do óbito ou fator contributivo. MÉTODOS: Estudo caso-controle retrospectivo, realizado no Instituto Central do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, no período de 1995 a 2004. Revisamos os relatórios diagnósticos das autópsias, identificando TEP fatal, quando TEP foi a causa de morte, e TEP não fatal, quando TEP foi doença associada. RESULTADOS: 1.506 pacientes (502 casos e 1.004 controles), 18.359 óbitos no período, média 2.040; 71,2% desses submetidos a autópsias. Observou-se importante declínio nas taxas de autópsias. De 1995-1999 (87,2%) e 2000-2004 (54,4%); p = 0,016. Dos 502 casos (3,8%), em 328 (2,5%) TEP foi causa de morte e 174 (1,3%), causa contributiva. Gênero: 51,6% homens e 48,4% mulheres. Idade: TEP fatal (328) vs controles (1.004), diferença estatisticamente significativa (p = 0,013). Condições prevalentes: câncer grupo, 31,4%, pós-operatório grupo, 17,2%, infecção grupo, 11,7%, e AVC grupo, 11%. Câncer de pulmão, 3,5%, câncer de cérebro e linfoma, 2,8%. Tempo de internação foi utilizado como indicador de imobilização. Outras doenças: AVCH (7,7%), pós-operatório de abdome (6,7%), pneumonia (5,9%), AVCI (3,1%) e pós-operatório vascular (4%) foram frequentes no grupo controle. Em contrapartida, aterosclerose (1,4%), ITU (1,2%), pós-operatório de ginecologia (0,8%), pós-operatório de obstetrícia (0,6%) e doença falciforme (0,6%) foram frequentes no grupo TEP. Cirrose, média de 14,9 dias de internação dos controles vs TEP com 4,4 dias (p < 0,001). Análise multivariada incluiu as condições com p 0,20 da univariada, idade e tempo de internação. Fator protetor para TEP: aneurisma de aorta (OR 0,02, IC 95% 0,46-0,56; p = 0,004), cirrose (OR 0,16, IC 95% 0,08-0,34; p < 0,001) e SIDA (OR 0,44, IC 95% 0,23-0,84; p = 0,013). Entretanto, AVCI (OR 1,82, IC 95% 1,04-3,19; p = 0,035), câncer de cérebro (OR 2,47, IC 95% 1,28-4,78; p = 0,007), câncer indeterminado (OR 3,12, IC 95% 1,01-9,68; p = 0,049), DPOC (OR 2,83, IC 95% 1,47-5,43; p = 0,002), ICC (OR 1,71, IC 95% 1,11-2,62; p = 0,015) e ITU (OR 4,34, IC 95% 1,05-17,82; p = 0,042) mostraram associação positiva com TEP. Idade vs TEP (OR 1,10, IC 95% 1,04-1,16; p = 0,001). Tempo de internação vs TEP (OR 1,19, IC 95% 1,05-1,36; p = 0,008). DISCUSSÃO: A porcentagem dos pacientes com TEP permanece inalterada, ocorrência de 4,1% e 3,4% no primero e no segundo períodos, com uma média de 3,8%. Em 50,4% dos pacientes não foi realizado o diagnóstico clínico de TEP. CONCLUSÃO: Constatou-se AVCI, câncer de cérebro indeterminado, DPOC, ICC e ITU com significância estatística e associação com TEP. Algumas fraquezas do presente estudo devem ser apuradas, e talvez explicarão as discordâncias com a literatura para algumas doenças. A identificação de fatores associados a TEP auxiliarão no diagnóstico precoce / INTRODUCTION: Literature shows that venous thromboembolism (VTE) remains as a sub-diagnostic disease among hospitalized patients, approximately 25% of all cases are associated to hospitalization. PURPOSE: Evaluate diseases associated to pulmonary thromboembolism (PE) development diagnosed in autopsies, and demonstrate the frequency of PE as cause of death or as a contributive factor. METHOD: The reports performed from 1995 to 2004 in a Brazilian tertiary referral medical school we reviewed for a retrospective study the autopsies diagnosis, identified as fatal PE, when PE was the cause of death and nonfatal PE, when PE was an associated disease. RESULTS: 1,506 patients (502 cases and 1004 controls), 18,359 deaths during the period, average 2,040; 71.2% of these were submitted to autopsies. It was observed an important decline in the autopsies rates. From 1995-1999 (87.2%) and 2000-2004 (54.4%) p = 0.016. From 502 cases (3.8%), 328 (2.5%) PE was the cause of death and 174 (1.3%) PE was contributive cause. Gender: 51.6% males and 48.4% females. AGE: fatal PE (328) vs controls (1,004) significant statistic difference (p = 0.013). Prevalent Conditions: cancer group, 31.4%, postsurgical group, 17.2%, infectious group, 11.7%, and CVA group, 11%. Pulmonary Cancer, 3.5%, Brain cancer and Lymphoma, 2.8%. Hospitalization period was taken as immobilization indicator. Other diseases: HCVA (7.7%), abdomen postsurgical (6.7%), pneumonia (5.9%), ICVA (3.1%) and vascular postsurgical (4%) were frequent in the control group. On the other hand, atherosclerosis (1.4%), UTI (Urinary Tract Infection) (1.2%), gynecology postsurgical (0.8%), obstetrics postsurgical (0.6%) and sickle cell anemia (0.6%) were frequent in the PE group. Cirrhosis, average of 14.9 hospitalization days of the controls vs PE with 4.4 days (p < 0.001). Logistic regression analysis includes the in univariated analysis with p 0.20, age and the hospitalization period. Protector factor for PE: Aortic aneurysm (OR 0.02, 95% CI 0.46-0.56; p = 0.004), cirrhosis (OR 0.16, 95% CI 0.08-0.34; p < 0.001) and SIDA (OR 0.44, 95% CI 0.23-0.84; p = 0.013). However, ICVA (OR 1.82, 95% CI 1.04-3.19; p = 0.035); brain cancer (OR 2.47, 95% CI 1.28-4.78; p = 0.007); undetermined cancer (OR 3.12, 95% CI 1.01-9.68, p= 0.049), COPD (OR 2.83, 95% CI 1.47-5.43; p = 0.002), CHF (OR 1.71, 95% CI 1.11-2.62; p = 0.015) and UTI (OR 4.34, 95% CI 1.05-17.82; p = 0.042), showed positive association with PE. Age vs PE (OR 1.10, 95% CI 1.04-1.16; p = 0.001). Hospitalization Period vs PE (OR 1.19, 95% CI 1.05-1.36; p = 0.008). DISCUSSION: The percentage of patients with PE remains unchanged, occurrence of 4.1% and 3.4% in the first and second periods, with an average of 3.8%. In 50.4% of the patients, the clinical diagnosis of TEP was not performed. CONCLUSION: We certified ICVA, brain cancer, undetermined cancer, COPD, CHF and UTI with significant association with PE. Some weaknesses of the present study should be refined, and maybe will explain the disagreement with the literature to some diseases. The identification of factors associated to PE will help in precocious diagnosis

Factors affecting outcome after primary intracerebral hemorrhage

Tetri, S. (Sami) 08 May 2009 (has links)
Abstract Primary intracerebral hemorrhage (ICH) accounts for 10–15% of all strokes. ICH is the most devastating subtype of stroke with high mortality and morbidity; 35–52% of patients die during the first month after the bleeding. The most important risk factor for onset of ICH is hypertension, especially untreated hypertension, and the well-known predictors for early death after ICH are a low GCS (i.e low level of consciousness) score on admission, the size of the hematoma, and the precence of intraventricular blood. Preceeding use of anticoagulants and advanced age further impair the outcome. Thromboembolic complications after the bleed are common and difficult to prevent. The present cohort study included all patients (n = 453) with verified primary ICH admitted to the stroke unit of Oulu University Hospital within a period of 11 years (from January 1993 to January 2004). The impacts of previous diseases, including ischemic heart disease, atrial fibrillation on admission, hypertension, and diabetes as well as of high admission blood pressure and plasma glucose levels on outcome were evaluated. The safety and efficacy of prevention of venous thromboembolism with enoxaparin, a low molecular weight heparin (LMWH), was investigated. In a population-based study covering a 3-year period, the risk factors and seasonal distribution of ICH were investigated. Independent of the severity of bleeding and patients’ age, ischemic heart disease, diabetes, and atrial fibrillation were found to be significant predictors for early death after ICH. High blood pressure on admission predicted early death, whereas elevated admission plasma glucose level was associated with the severity of bleeding but was not an independent predictor for early death. Treatment with enoxaparin (20 mg per day subcutaneously) for prevention of venous thromboembolism was not associated with increased mortality but did not seem to prevent venous thromboembolic complications. The incidence of ICH was higher during the winter among patients with untreated hypertension but not in normotensive and treated hypertensive patients.
