This research project investigated the impact of an action research intervention implemented to reducing surgical wound infection in one of the acute care hospitals in India. The study aimed to develop and implement a clinical practice improvement program in reducing surgical wound infection by improving the hand washing and wound dressing practices of nurses. The study also aimed to identify the important contributing factors to a model that predicts surgical wound infection. Pre-post evaluation measures were taken to compare the results of surgical wound infection rate before and after the implementation of the intervention. Surgical wounds of two thousand patients (one thousand before the intervention and another one thousand after) were assessed to determine the wound infection rate and severity of wound infection. The hand washing and wound dressing practices of forty nurses were observed. These same nurses were involved in the intervention using a participatory action research process. The results of the study suggest that there was a marked, significant reduction in the rate and severity of wound infection following the implementation of the intervention. By increasing the hand washing facilities in the ward, educating nurses on the importance of better hygiene, pre-operative shaving and post-operative wound care, the hand washing and wound dressing practices of nurses improved considerably. These improvements resulted in a reduction in the number and severity of patients' surgical wound infections. The study also examined the contribution of different factors to surgical wound infection in a Indian hospital. Significant predictive factors were the patients' age, longer pre-operative hospital stay, extended pre-operative shaving time before surgery, wound class, and co-morbidity of the patient. The identification of risk factors that contributed to increased surgical wound infection for example pre-operative skin preparation, pre-operative hospital stay of the patient would help in taking appropriate measures at the ward level and organisation as a whole. Nosocomial infections extends to an unnecessary lengthy hospital stay, additional treatment increased mortality and morbidity, and increased cost to the patients and the nation as a whole. This project proved that educational mentoring, data surveillance processes and involving the nurses in an action research process were effective in enabling participants to improve their clinical practice and thereby reduce the incidence of patients' surgical wound infections. Establishing infection control teams, ongoing surveillance and feedback to staff of nosocomial infection rates is an urgent need in all Indian hospitals. Organisational management, as a priority, need to provide funding and staff dedicated to undertaking this essential work. Health care professionals can no longer plead ignorance of a situation for which all have a moral and professional responsibility.

Métodos: Foi realizado um ensaio clínico piloto duplo cego controlado aleatorizado. Mulheres com indicação de cesárea, com até uma cesárea prévia, que fizeram pré-natal foram aleatorizadas na hora da cirurgia para uso ou não de eletrocautério para coagulação. As 224 voluntárias que participaram foram examinadas na alta hospitalar (3o dia) e pós-alta, no 7°.ao 10° dia e 30° ao 40° dia. Foram avaliados sinais infecciosos, hematoma, seroma e deiscência. A amostra foi calculada baseada em uma prevalência de infecção pós-alta de 14,4%, estimando-se um risco adicional de 15% para o grupo com uso de eletrocautério, totalizando 224 voluntárias. Os dados foram analizados por intenção de tratamento e a razão de risco foi calculada. Resultados: Os grupos foram similares quanto à demografia, paridade, consultas de pré-natal, índice de massa corporal e cesárea prévia. Durante a internação, apenas 2,8% das mulheres com uso de eletrocautério apresentaram complicações na ferida operatória. As taxas de complicações alcançaram 15,4% no grupo sem cautério, chegando a 23% no outro grupo, 7-10 dias pós-alta (RR=1,50 0,84-2,60). Foram observadas poucas complicações no 30° ao 40°dia e no grupo sem cautério (RR=1,15, 95% IC=0,61-2,16). A cesárea durou 105 e 100 minutos sem e com cautério, respectivamente (p=0,54). Não foi observada nenhuma arritmia cardíaca neonatal. Conclusão: O uso de cautério não se mostrou de maior risco para complicações na ferida operatória de cesárea, sendo necessários mais estudos que deem continuidade e ampliem os conhecimentos em procedimentos realizados em gestantes / Abstract: Purpose: To estimate the risk for wound complications when electrocautery is available for coagulation during cesarean section. Methods: A randomized controlled trial of using electrocautery for coagulation was performed among 224 women with none or one previous cesarean who had their pregnancy terminated with an abdominal delivery. Volunteers who accepted to participate were examined before discharge (3rd day), when the skin suture was removed (7-10 days), and 30-40 days after surgery. Infection signs, haematoma, seroma, and scar dehiscence were searched during visits. Sample size was calculated based on 14.4% prevalence of infection after discharge, estimating 15% added risk for the group using electrocautery, totalizing 224 volunteers. Unadjusted and adjusted prevalence risk (age, schooling, obesity, previous cesarean) were calculated. Results: Both groups were similar regarding demographics, parity, antenatal care, body mass index, and previous cesarean. During hospital stay, none among 96 women without electrocautery, and 2.8% of 97 women using electrocautery showed wound complications. The figures reached 15.4% and 23% respectively after 7-10 days (unadjusted RR = 1.50, 0.84-2.60). Few other complications were observed later, only among the non-intervention group (RR=1.15, 95% CI = 0.61-2.16). The lack of effect was maintained after adjusting for age, schooling, obesity, and previous cesarean (RR=1.47, 0.77-2.81). Surgical procedure lasted 105 and 100 minutes for both groups (p=0.54). No neonatal arrhythmia was observed. Conclusion: There is no evidence to recommend the use of electrocautery for coagulation during cesarean delivery. Wound complications were concentrated on post-discharge period for both groups / Mestrado / Tocoginecologia / Mestre em Tocoginecologia

Entre 12% e 84% dessas infecções são detectadas depois que o paciente deixa o hospital, daí a importância da realização da vigilância pós-alta hospitalar. OBJETIVOS: Implementar um serviço de vigilância pós-alta de ISC em mulheres que realizaram cirurgia ginecológica em um Hospital de Ensino em Teresina-PI; monitorizar a ocorrência de ISC e sua associação com fatores de risco; caracterizar o perfil sociodemográfico desse contingente; determinar a taxa de incidência de ISC no ambulatório de ginecologia por meio da vigilância; e identificar o perfil das ISC diagnosticadas após a alta hospitalar. MÉTODO: Estudo quantitativo e prospectivo, realizado no ambulatório de ginecologia do Hospital Getúlio Vargas, o qual é de ensino público, geral, de grande porte e de referência em saúde para o Estado do Piauí e demais regiões do Norte e Nordeste do Brasil. A população foi de 1.026 mulheres egressas do hospital de ensino, que realizaram cirurgia ginecológica, no período de junho de 2011 a março de 2013. O projeto foi aprovado pelo Comitê de Ética e Pesquisa da UFPI, sob o CAAE: 0059. 045. 000.11. RESULTADOS: Utilizou-se a vigilância epidemiológica às ISC do tipo busca ativa, por 30 dias, no ambulatório de ginecologia, por meio de contato presencial e telefônico. A taxa de retorno das mulheres para o ambulatório foi de 86,6% e a incidência de ISC foi de 5,8%, destas, 71,7% foram classificadas como incisional superficial e 28,3% como incisional profunda. O tempo médio entre a cirurgia e o diagnóstico de ISC foi de 12,9 dias; a maior incidência se encontra na faixa etária de 25 a 44 anos (44,3%) de idade; procediam da capital 57,8% e, do interior do Estado, 42,2%; 63% são casadas, 61% tinham até o ensino fundamental; economicamente, 46,4% declararam renda familiar de 1 (um) salário mínimo. Os fatores de risco para o desenvolvimento de ISC foram: Tempo PO (dias), Neoplasia e Diabetes mellitus. CONCLUSÃO: Evidenciou-se o incremento da notificação de incidência de ISC, o que aponta para a importância do acompanhamento das mulheres sob vigilância pós-alta, utilizando uma estratégia sistematizada.

Because of the high cost of some wound management regimens, payors may require that moist wound therapies be used before other treatment approaches, such as negative pressure wound therapy (NPWT), are implemented but few studies have investigated the effect of delayed initiation of NPWT on patient outcomes. To examine the impact of early versus late initiation of NPWT on patient length of stay in home health care, a nonrandomized, retrospective analysis was performed on the Outcome and Assessment Information Set (OASIS) information for home care patients with NPWT-treated Stage III or Stage IV pressure ulcers (N = 98) or surgical wounds (N = 464) gathered between July 2002 and September 2004. Early initiation of NPWT following the start of home care was defined as <30 days for pressure ulcers and <7 days for surgical wound patients. Median duration of NPWT was 31 days (range 3 to 169) for pressure ulcers and 27 days (range 5 to 119) for the surgical wound group. Median lengths of stay in the early treatment groups were 85 days (range 11 to 239) for pressure ulcers and 57 days (range 7 to 119) for the surgical group versus 166 days (range 60 to 657) and 87 days (range 31 to 328), respectively, for the late treatment pressure ulcer and surgical groups (P <0.0001). After controlling demographic patient variables, regression analysis indicated that for each day NPWT initiation was delayed, almost 1 day was added to the total length of stay (β = 0.96, P <0.0001 [pressure ulcers]; β = 0.97, P <0.0001 [surgical wounds]). Early initiation of NPWT may be associated with shorter length of stay for patients receiving home care for Stage III or Stage IV pressure ulcers or surgical wounds. Additional studies to ascertain the cost-effectiveness of treatments and treatment approaches in home care patients are needed.

O avental cirúrgico, um dos principais componentes de barreira antimicrobiana, é confeccionado com materiais de tecido e não-tecido. A Sociedade Norte-Americana de Enfermeiros do Centro Cirúrgico - AORN e a Norma Européia - EN 13795-3 recomendam que os aventais cirúrgicos devam prover uma barreira apropriada contra microrganismos, sangue e outros fluidos corpóreos (seco ou molhado). Tais recomendações, no entanto, não definem o que consideram como \"barreira apropriada\". O que ainda não foi comprovado, porém, é se o uso de materiais de não-tecido realmente interfere, isoladamente, tanto na contaminação da ferida operatória, quanto na ocorrência de ISC. O presente estudo teve como objetivo verificar se há evidências científicas, pela revisão sistemática de literatura, que fundamentem a prática do uso de aventais em cirurgias, conforme seu material de confecção. Foram considerados para a revisão sistemática apenas estudos básicos de intervenção, que investigaram a contaminação e ou a infecção do sítio cirúrgico com uso de aventais cirúrgicos reutilizáveis e ou de uso-único, utilizando como população pessoas submetidas a cirurgias, em situações reais ou simuladas, em qualquer período, sem limitação de idioma. Para localizar os estudos, utilizou-se a estratégia: P (pacientes) = pacientes cirúrgicos - surgical patients, I (intervenção) = roupa hospitalar ou roupa de proteção – clothing / protective clothing, C (comparação) = uso-único ou reutilizável - single-use or reusable, O (desfecho) = contaminação ou infecção da ferida operatória – surgical wound infection/contamination. A busca dos estudos orientou-se pelas bases de dados eletrônicas: LILACS, CINAHL, EMBASE, COCHRANE, PubMed/MEDLINE, pesquisa manual na revista da Sociedade Brasileira de Enfermeiros de Centro Cirúrgico (SOBECC) e referências dos estudos incluídos. Os dados analisados foram apresentados em três fases: Fase 1: Caracterização do processo de seleção dos estudos; Fase 2: Caracterização dos estudos incluídos; Fase 3: Avaliação da evidência dos estudos incluídos, a partir de duas escalas de qualidade, sendo uma delas a de Jadad e outra a de Controle de Infecção Cirúrgica (EQCIC), adaptada de Nobre e Bernardo. A amostra desta revisão sistemática constituiu-se de 12 estudos, sendo que apenas um deles investigou o avental isoladamente. Os demais investigaram principalmente os campos cirúrgicos juntamente com os aventais. Constata-se, com isso, dificuldade de isolar o objeto de intervenção de outros inúmeros fatores que podem interferir nos desfechos, em estudos desta natureza. Dois estudos (E1, E2) obtiveram forte evidência de recomendação, concluindo pela não diferença de contaminação e infecção do sítio cirúrgico entre aventais e campos de tecido e não-tecido. Devido à ausência de estudos semelhantes não houve a possibilidade de realizar a metanálise. A verificação isolada de aventais cirúrgicos depende de mais pesquisas bem controladas e delineadas. A contribuição desta investigação para a implementação de prática baseada em evidências mostrou-se relevante não somente para responder especificamente à questão da pesquisa, mas também para identificar qualidade, lacunas, falhas e recomendar aspectos a serem considerados nas próximas pesquisas desta natureza / The surgical gown, one of the main components of the antimicrobial barrier, is confectioned with woven and non-woven materials. The American Operating Room Nursing - AORN and The European Norm - EN 13795-3 recommend that the surgical gowns should provide an appropriate barrier against microorganisms, blood and other organic fluids (dry or wet). These recommendations, however, do not define, yet, what to consider an \"appropriate barrier\".. What has not been proved yet is if the use of non-woven materials influence, in an isolated way, both the contamination of an operation wound, and the occurrence of ISC. It was the objective of this present study to investigate if there is scientific evidence, by means of systematic revision, that founded the practice of use of gowns in surgery, according to its material of confections. Only basic studies of intervention that investigated the contamination and or surgical site infection with the use of surgical gowns reusable or single-use were considered in the systematic revision, which used as population people who underwent surgery, in real or simulated situations, in any period, without idiom limitation. To locate the studies, we used the PICO strategy: P (patients): surgical patients, I (intervention) = clothing/protective clothing, C (comparison) = single-use or reusable, O (outcome) = contamination or surgical wound infection. The search of studies was guided by the following electronic data bases: LILACS, PubMed/MEDLINE, EMBASE, COCHRANE, CINAHL, manual research in the magazine of Brazilian Society Operating Room Nursing (SOBECC) and references of included studies. The data analyses were shown in three phases: Phase 1: characterization of process of select studies; Phase 2: characterization of included studies; Phase 3: evaluation of the evidence found in the included studies, using two quality scales, being one this The Jadad and other Surgical Infection Control (EQCIC), adapted from Nobre and Bernardo. The sample of this systematic revision comprises 12 studies, being only one of them analyzed only gowns. The remainder investigated mainly the surgical fields together with the gowns. We can see thereby the difficulty in isolating the object of intervention from other countless factors that can influence outcomes, in studies of this nature. Two studies (E1, E2) found strong evidence of recommendation, concluding that there is no difference in terms of contamination and surgical wound infection between woven and non-woven gowns and drapes. Due to the absence of similar studies it is not possible to do some metanalysis. The isolated verification of surgical gowns needs more well controlled and delineated research. The contribution of this investigation to the implementation of practices based on evidences in showed relevant not only to answer specifically the question of research, but also to identify quality, gaps and flaws and recommend aspects to be considered in future research of this nature

Introdução: As infecções do sítio cirúrgico (ISC) estão entre as principais complicações em pacientes submetidos ao transplante de fígado, com incidências que variam de 10,4% a 23,6%. Ademais, recente revisão da literatura aponta lacunas entre os fatores de risco para esta população específica. Objetivo: Analisar a incidência e os fatores de risco para o desenvolvimento de ISC entre pacientes adultos submetidos ao transplante de fígado. Método: Coorte histórica, realizada por meio de consulta a prontuários de pacientes adultos submetidos ao transplante de fígado entre os anos de 2009 e 2015, em um hospital filantrópico do interior do Estado de São Paulo. O projeto foi aprovado pelo Comitê de Ética em Pesquisa da Escola de Enfermagem da Universidade de São Paulo. Para análise dos dados utilizou-se medidas de tendência central e de variabilidade, os testes 2 de Pearson, teste exato de Fisher, Mann-Whitney e Wilcoxon-Mann-Whitney. Após análise bivariada, as variáveis foram incluídas em um modelo de regressão Classification and Regression Tree. Resultados: Foram investigados os prontuários de 156 pacientes submetidos ao transplante de fígado, dos quais 26,9% desenvolveram ISC. Verificou-se que elevado tempo cirúrgico (>487 minutos) associado a diferenças de índice de massa corporal entre doador e receptor (>1,3 kg/m2) aumentaram a chance de ISC em aproximadamente 5,5 vezes (OR 5,5; IC 95% 2,5-11,8); e glicemia capilar (>175 mg/dl) nas primeiras 96 horas de pós-operatório elevou a chance de ISC em aproximadamente três vezes (OR 2,97; IC 95% 1,43-6,17). Os principais micro-organismos isolados em sítios de coleta diretamente relacionados à ISC foram Staphylococcus sp., P. aeruginosa, Klebsiella sp., A. baumanii e C. albicans. Conclusão: Encontrou-se elevada incidência de ISC entre a população estudada. Os fatores de risco encontrados para esta categoria de pacientes diferem dos amplamente apontados pela literatura científica em outras categorias ou especialidades cirúrgicas. / Introduction: Surgical site infections (SSI) are one of the main liver transplantation complications with incidence varying between 10.4% to 23.6%. Recent literature review shows gaps between risk factors within this specific population. Objective: To analyze the incidence and the risk factors in the development of SSI among adults submitted to liver transplantation. Methods: Historical cohort done through records of adults submitted to liver transplant between 2009 and 2015 in a philanthropic hospital in the countryside of Sao Paulo state. The Research Ethics Committee of School of Nursing of University of Sao Paulo approved the project. Data was analyzed by central tendency and variability measures, Pearson X2-test, Fisher exact test, Mann Whitney test and Wilcoxon-Man Whitney test. After the bivariate analyzes, the variables were included in the Classification and Regression Tree model. Results: The records of 156 patients submitted to liver transplant were investigated, of which 26.9% developed SSI. Prolonged operative time (>487 minutes) associated with Body Mass Index differences between donator/receptor (>1.3kg/m2) increased the chance of SSI in approximately 5.5 times (OR 5,5; CI 95% 2,5 - 11,8); and in the first 96 postoperative hours capillary glycemia (>175 mg/dl) increased the chance of SSI in approximately three times (OR 2.97; CI 95% 1.43 6.17). The main microorganisms isolated in collection sites related to SSI were Staphylococcus sp., P. aeruginosa, Klebsiella sp., A. baumanii and C. albicans. Conclusion: There is high incidence of SSI among the studied population and the identified risk factors for this patients category are highly diverse from the ones indicated by scientific literature in other categories or surgical specialties.
