<p>Postoperativ sårinfektion är en komplikation som var tionde patient drabbas av efter ett kirurgiskt ingrepp. Det medför inte bara lidande och förlängd vårdtid för patienten utan kan även vara direkt livshotande.

Abstrakt Bakgrund: Länge har man varit medveten om vikten av god hygien och dess inverkan på smittspridning. Det mest effektiva sättet att minska postoperativa sårinfektioner (SSI) är att arbeta förebyggande och att ha en god hygien. Frekvensen av SSI ökar, och som en del av den förebyggande vården ingår den preoperativa förberedelsen. Att inte ha kunskap och stöd till att utföra en sådan åtgärd korrekt är en stor brist och kan leda till att patienter drabbas av SSI och därmed ett ökat postoperativt lidande. Syfte: Studiens syfte var att beskriva vårdpersonalens syn på betydelsen av hygienisk preoperativ förberedelse hos ortopedpatienter. Metod: Studien genomfördes på ett länssjukhus i mellersta norrland under våren 2008, där alla ortopedavdelningar på sjukhuset deltog. En kvalitativ intervjumetod användes med manifest innehållsanalys av materialet. Resultat: All personal som ingått i studien anser att den hygieniska preoperativa förberedelsen är av stor vikt. Trots faktorer som stress, personalbrist och hög arbetsbelastning kände personalen att de ville vara noggrann i sitt arbete och göra det bästa för patienten, även genomföra en bra förberedelse innan operation. Den största orsaken till att de frångick de skrivna rutinerna var att patienterna hade ont, samt vid akuta situationer då det var svårt att planera sitt arbete. Diskussion: Trots att personalen visste om förberedelsens betydelse för frekvensen av SSI och att de tyckte att riktlinjerna inte förändrats på många år, valde de medvetet att vissa gånger frångå de rutiner som finns och de tog inget eget ansvar för att hålla sig uppdaterad kring ny forskning. / Abstract Background: Long has one been aware about the importance of good hygiene and its effect on infection control. The most effective way to decrease surgical site infections (SSI) is to work preventive and to have a good hygiene. The frequency of SSI increases and as a part of the preventive care the hygienic preoperative preparation is included. To not have knowledge and aids to carrying out such a measure correct is a big deficiency and can lead to patients being hit of SSI and with that increased postoperative suffering Aim: The study's aim was to describe the care personnel's view on the importance of hygiene preoperative preparation at orthopaedic patients. Method: The study was implemented on a county hospital in the north central part of Sweden during the spring of 2008, where all orthopaedic departments on the hospital participated. A qualitative interview method was used with a manifest content analysis of the material. Results: All personnel as been included in the study were unanimous that hygienic preoperative preparation was of big importance. Despite factors like stress, lack of personnel and high workload, they wanted to be accurate in their work and do what’s best for the patient. That also implemented a good preparation before operation. The major reason to not follow the guidelines where that the patients was in acute pain, and in emergency situations when it were impossible to plan its work. Discussion: Despite the knowledge about the importance of preparation for the frequency of SSI and they thought that the guideline not been changed on many years, they sometimes deliberately chose not to follow the guideline. The nurses took no responsibility in order to keep updated around new research.

Made available in DSpace on 2015-07-22T20:49:30Z (GMT). No. of bitstreams: 0 Previous issue date: 2009-10-28 / Introdução: Altas taxas de infecção podem refletir a qualidade de um serviço de saúde. Considerando-se que as taxas de infecção de sítio cirúrgico (ISC) encontradas em estudos prévios no local do presente estudo variaram de 14,1% a 22%, questionou-se se a estrutura e o processo assistencial de enfermagem estariam influenciando estas taxas. Uma vez obtida esta resposta, outra indagação relacionou-se à capacidade de um programa educativo de gerar a construção de propostas ou projetos de mudanças por parte dos seus participantes, a partir e uma dinâmica que prime pela interatividade. Objetivo: Avaliar a estrutura e processo assistencial de enfermagem e um programa educativo para os enfermeiros, com o uso de estratégias educacionais interativas, para a prevenção e controle de ISC. Método: Estudo de intervenção, aprovado pelo Comitê de Ética em Pesquisa da UNIFESP sob o número 1486/07, desenvolvido em duas etapas. A primeira consistiu de um estudo observacional e de análise documental, realizado por meio de auditorias de estrutura e processo, na Unidade de Ginecologia e Setor de Oncomastologia do Hospital São Paulo (HSP), entre agosto de 2007 e março de 2008. Esta fase do estudo foi descrita no primeiro artigo que compõe o corpo desta tese. A segunda, de abordagem quali-quantitativa, foi realizada no período de outubro de 2008 a setembro de 2009 e compreende a estruturação, desenvolvimento e avaliação do projeto educacional em ambiente virtual voltado para as enfermeiras dos setores acima mencionados, para controle de ISC, baseado no Modelo Skopos e organizado a partir dos recursos do ambiente Moodle. O conjunto de dados desta etapa foi descrito nos três artigos subsequentes que compõem a tese. Resultados: A avaliação da estrutura e processo assistencial de enfermagem evidenciou que os documentos normativos estavam em consonância com o preconizado na literatura, porém, a estrutura física e os processos assistenciais dos locais pesquisados apresentavam limitações importantes com impacto negativo para o desenvolvimento dos processos assistenciais adequados à prevenção de ISC. No que se refere à estruturação e utilização de um ambiente virtual de aprendizagem na educação continuada em enfermagem, o Moodle mostrou-se valioso para estruturação de um programa educativo de enfermagem, que buscou distanciar-se do modelo de comunicação unilateral e hierárquico. A avaliação do alcance dos objetivos e da adequação dos conteúdos propostos pelo referido programa, por parte das quatro enfermeiras que participaram do processo, mostrou que as mesmas têm clareza dos benefícios e dos principais fatores limitantes atrelados aos programas educativos. E, ainda, embora novas estratégias pedagógicas, particularmente interativas, sejam bem-vindas, as profissionais preferiram os encontros presenciais para verbalização e organização das reflexões. Finalmente, a aplicação das ferramentas HFMEA® e diagrama de Ishikawa possibilitou a análise de quatro processos assistenciais de enfermagem e seus modos de falha: 1) Agendar cirurgia via Setor de Oncomastologia; 2) Fluxo de Admissão e Alta de Paciente Cirúrgico na Unidade de Internação de Ginecologia; 3) Realização de Procedimentos Cirúrgicos Ambulatoriais; 4) Retorno Ambulatorial de Pacientes Cirúrgicos. Possibilitou, ainda, a elaboração de ações de melhoria que foram iniciadas a partir das discussões realizadas no programa. Conclusões: Os resultados do estudo evidenciaram a necessidade de revisão do processo assistencial de enfermagem e adequação da estrutura, a fim de que os padrões de prevenção e controle da ISC fossem atendidos. Em relação ao programa educativo, a experiência de uso de tecnologia educacional na instituição em questão mostrou-se factível e propiciou a reflexão conjunta sobre a situação-problema vivenciada, bem como a proposta de ações para sua solução. Porém, como todo processo inovador, há uma trajetória a ser construída para que os enfermeiros habituados ao estilo expositivo, presencial e focado em objetos previamente determinados, sejam capazes de se beneficiarem de estratégias interativas, colaborativas e baseadas em projetos. / Introduction: High rates of infection can reflect low health service quality. The fact that previous studies performed at the same location of the present study found surgical site infection rates (SSI) ranging from 14.1% to 22% raised questions about the possibility of the nursing care structure and process to affect those rates. After obtaining this first answer, another question emerged, concerning the capacity of an inservice training program be able to encourage the participants, by means of an interactive dynamics, to develop proposals or projects from making changes. Objectives: To evaluate nursing care structure and process in preventing and managing SSI; and evaluate an inservice training program for nurses involved in the context of the identified problems, using interactive educational strategies aiming at the prevention and control of this complication. Method: This intervention study was approved by the UNIFESP Research Ethics Committee under register 1486/07, and was developed in two stages. The first stage consisted of and observation and analysis study, performed by means of inspections of the structure and process at the Gynecology Oncomastology Units at Hospital São Paulo (HSP), between August 2007 and March 2008. This stage was described in the first article that composes this dissertation. The second stage used a quali-quantitative approach and was performed from October 2008 to September 2009. It consisted of the structure, development, and evaluation of the educational project in a virtual environment for the Training Program at Work for nurses of the referred hospital units, in SSI control, based on the Skopos Model, and organized based on the resources of the Moodle environment. The data regarding this stage was described in the three subsequent articles that comprise the dissertation. Results: The evaluation of the nursing care structure and process showed that the normative document were in agreement with the literature; however, the physical structure and the nursing care processes of the studied locations presented important limitations, which had a negative impact on the development of adequate health care processes to prevent SSI. In terms of the structure and use of a virtual learning environment in continuing nursing education, Moodle showed to be valuable in structuring a nursing training program, which sought to stand apart from a unilateral and hierarchical communication model. The evaluation of goal achievement and content adequacy of the referred program was performed by four nurses who participated in the process. The nurses found that the program presents clear benefits and the main limiting factors associated with inservice training. In addition, although new educational strategies, particularly if interactive, are welcome, the professionals preferred in-person meetings. Finally, using the HFMEA® and the Ishikawa diagram permitted to analyze four nursing care processes and their forms of failure: 1) scheduling a surgery through the Oncomastology Unit; 2) Surgery Patient Admission and Discharge Flow at the Gynecology Hospitalization Unit; 3) Performing Outpatient Surgical Procedures; 4) Outpatient Return Appointments for Surgery Patients. In addition, it was possible to make a list of improvement actions that were initiated based on the discussions held during the training program. Conclusions: The study results evidenced the need to review the nursing care process and to make the structure adequate with a view to meet the standards for SSI prevention and control. As for the inservice training program, the experience of using educational technology at the referred institution was feasible and provided the chance for group analyses about the problematic situation, as well as the proposal of actions for its solution. However, just as any innovative process, there is a pathway to be constructed so that nurses, who are used to training programs that are expositive, performed on-site and focused on previously determined objectives become capable of benefiting from interactive, collaborative, and project-based strategies. / TEDE

No. of bitstreams: 0 Previous issue date: 2010-08-25 / Introdução: o cuidado com a ferida operatória é controverso na literatura, com recomendações diversas, desde não se colocar curativo, mantê-lo por 24 a 48h, ou mantê-lo até a retirada das suturas. Objetivo: Avaliar a influência do tempo de permanência do curativo após mamoplastia redutora na colonização cutânea, na infecção da ferida operatória e na opinião das pacientes. Métodos: 70 pacientes com indicação para mamoplastia redutora foram distribuídas aleatoriamente em dois grupos. No grupo PO1 o curativo foi retirado no 1o dia pós-operatório e no grupo PO6 o curativo foi retirado no 6º dia pós-operatório. A colonização cutânea foi verificada por meio de culturas de coletas em momentos padronizados. A avaliação da ferida operatória quanto à infecção seguiu os critérios definidos pelo Centers for Disease Control and Prevention (CDC). A opinião das pacientes quanto ao curativo foi verificada no 13º dia pós- operatório. Resultados: no 6º dia pós-operatório houve um maior número de unidades formadoras de colônias, no grupo PO1. Nove pacientes (12,9%) apresentaram infecção, sete no grupo PO1 (20%) e duas no grupo PO6 (6%). Das pacientes do grupo PO1, 66% prefeririam manter o curativo por um dia e do grupo PO6, 83% prefeririam manter o curativo por seis dias. Conclusões: a colonização no 6º dia pós-operatório foi maior no grupo PO1. Não houve diferença entre os grupos quanto à ocorrência de infecção da ferida operatória. As pacientes demonstraram preferência e acharam mais seguro a permanência do curativo até o sexto dia pós-operatório. / Background: There is controversy in the literature regarding the treatment of surgical wounds, which includes different approaches to wound management, such as “not to dress the wound” to “leave the dressing in place for 24-48 hours” or “until sutures are removed”. Objective: To evaluate the effect of the length of time the dressings were left in place after reduction mammaplasty on skin colonization, surgical site infection, and patient opinion. Methods: Seventy patients undergoing reduction mammaplasty were randomly divided into two groups: group PO1 (dressing was removed on the first postoperative day) and group PO6 (dressing was removed on the sixth postoperative day). Skin colonization was detected by culture of samples collected at predefined time points. Surgical site infections were classified according to the guidelines of the Centers for Disease Control and Prevention (CDC). Patient satisfaction was assessed on postoperative day 13. Results: A larger number of colony-forming units were measured in group PO1 on postoperative day 6. Nine (12.9%) patients had surgical site infection (seven from group PO1, and two from group PO2). In group PO1, 66% of the patients chose to keep the dressing for one day, while 83% of the patients in group PO6 chose to keep the dressing for six days. Conclusions: Higher colonization levels were observed in group PO1 on the sixth postoperative day. There was no difference in surgical site infection between groups. Most of the patients chose to keep the dressing in place for six days postoperatively, and felt it was safer. / TEDE / BV UNIFESP: Teses e dissertações

Introdução: Os eventos adversos relacionados à assistência à saúde estão associados ao aumento da morbimortalidade e as IRAS correspondem entre 15% a 25% desses eventos. Há escassez de novos antimicrobianos, aumento de cepas resistentes e alto consumo dessas drogas. A adesão às diretrizes de antibioticoprofilaxia cirúrgica é pouco satisfatória e no Brasil há poucos dados sobre o assunto. Objetivo: reconhecer as características e iniciativas institucionais que aprimoram as práticas de uso de antibioticoprofilaxia em neurocirurgia. Objetivos específicos: identificar a conformidade; verificar a associação da conformidade com características de pacientes, cirurgias, hospitais, SCIH e processos relacionados à prevenção de ISC e uso de antibioticoprofilaxia; reconhecer a percepção de anestesiologistas e neurocirurgiões sobre as diretrizes institucionais. Método: Estudo observacional transversal, com população formada por hospitais, prontuários de pacientes neurocirúrgicos, profissionais dos SCIH, anestesiologistas e neurocirurgiões. A amostra de hospitais, anestesiologistas e neurocirurgiões foi tomada por conveniência e o número de prontuários para cada hospital foi calculado com base em 40% de conformidade geral. Resultados: Entre os nove hospitais avaliados, seis são privados, sete de grande porte e cinco tinham certificação de qualidade em 2010. O tempo médio de existência das CCIH foi de 21,9 anos e o dos SCIH de 19,4 anos. A média de horas semanais de profissionais do SCIH/leito hospitalar e por leito crítico foi 0,7 e 3,8, respectivamente. Oito hospitais divulgavam taxas de ISC, sete estratificada por especialidade cirúrgica. Seis hospitais construíram as diretrizes de antibioticoprofilaxia com anuência dos cirurgiões; em quatro deles as recomendações estavam completamente disseminadas e a taxa de adesão era monitorada e divulgada. As 1.011 neurocirurgias (craniotomias, artrodeses, laminectomias outras cirurgias), foram realizadas predominantemente em pacientes do sexo masculino, sendo a média de idade 49,6 anos. Foram excluídos da análise 38 procedimentos por falta de registro. A conformidade geral foi 10,0%; os maiores índices ocorreram nos hospitais 3 (28,9%), 1 (18,2%) e 8 (16,4%), ficando abaixo de 5% nos demais. No Hospital 9 a conformidade geral foi zero. A via administração estava conforme em 100% das neurocirurgias, dose em 90,6%, indicação em 90,0% e momento de início em 77,1%. Houve menor conformidade quanto à duração (26,1%), em 62,2% dos casos, mais longa que o recomendado. Houve associação estatisticamente significativa entre horas de profissionais do SCIH/leito de UTI (p 0,048), divulgação das diretrizes de uso de antibioticoprofilaxia cirúrgica (p 0,035), monitoramento da adesão (p 0,024), divulgação (p 0,015) dos resultados e a conformidade geral; período do dia em que a cirurgia ocorreu, dose (IC 1,72-6,65) e momento de início (IC 1,12-3,01) e tipo de cirurgia, momento de início (IC 1,24-4,25) e duração (IC 1,09-2,59). Foram entrevistados 43 profissionais de seis hospitais. Mais de 80% conheciam e concordavam as diretrizes institucionais e mais da metade referiu sempre segui-las; 37,0% dos anestesiologistas e 50,0% dos cirurgiões acreditavam que as diretrizes eram quase sempre seguidas por outros profissionais. Um cirurgião referiu nunca seguir e acreditar que outros profissionais nunca seguiam as diretrizes. As principais observações dos entrevistados foram falta de disciplina no centro cirúrgico e não divulgação das diretrizes de uso de antibioticoprofilaxia. Foi sugerido ao SCIH realizar treinamentos, disponibilizar amplamente as diretrizes, monitorar e divulgar a adesão às mesmas. Conclusão: O número de profissionais do SCIH/leito crítico, a divulgação das diretrizes, o monitoramento e a divulgação de resultados estão associados a maior conformidade quanto ao uso antibioticoprofilaxia cirúrgica. As inadequações identificadas parecem ter maior relação com resistência microbiana do que com ISC. Os SCIH tinham estrutura conforme exigido pela legislação, mas apresentavam lacunas quanto ao processo de implantação das diretrizes, monitoramento e divulgação de resultados. É imprescindível maior aproximação dos SCIH, especialmente, com os indivíduos envolvidos no processo cirúrgico, bem como a busca por soluções inovadoras, uma vez que os métodos convencionais de intervenção não estão produzindo os resultados desejados. / Introduction: healthcare-related adverse events are associated with increased morbidity and mortality and the Healthcare-associated Infections (HAI) account for 15% to 25% of these events. There is a shortage of new antimicrobials, increase in resistant strains and high consumption of these drugs. Adherence to surgical antibiotic prophylaxis guidelines is poor and there is little data on the subject in Brazil. Objective: to recognize the characteristics and institutional initiatives to improve antibiotic prophylaxis practices in neurosurgery. Specific objectives: identify adherence; verify the association of adherence with characteristics of patients, surgeries, hospitals, Hospital Infection Control Team (ICT) and processes related to prevention of Surgical Site Infection (SSI) and use of antibiotic prophylaxis; recognize the perception of anesthesiologists and neurosurgeons on institutional guidelines. Method: Cross-sectional observational study, carried out with a population consisting of hospitals, medical records of neurosurgical patients, ICT professionals, anesthesiologists and neurosurgeons. The sample of hospitals, anesthesiologists and neurosurgeons was used for convenience and the number of records for each hospital was calculated based on 40% of overall adherence. Results: Among the nine assessed hospitals, six are private, seven are large and five achieved quality certification in 2010. The mean time of Hospital Infection Control Committee (HICC) was 21.9 years and of ICT was 19.4 years. The mean weekly hours of ICT professionals per hospital bed and per critical bed was 0.7 and 3.8, respectively. Eight hospitals disclosed SSI rates, seven stratified by surgical specialty. Six hospitals created the antibiotic prophylaxis guidelines with the surgeons approval; the recommendations were fully disseminated in four and the rate of adherence was monitored and disclosed. The 1,011 neurosurgeries (craniotomy, arthrodesis, laminectomy and other surgeries), were performed predominantly in male patients with a mean age of 49.6 years. A total of 38 procedures were excluded from the analysis due to lack of records. Overall adherence was 10.0%; the highest rates were observed in Hospitals 3 (28.9%), 1 (18.2%) and 8 (16.4%), being <5% in the others. Overall adherence was zero in Hospital 9. The administration route was appropriate in 100% of the neurosurgeries, dose was appropriate in 90.6%, indication in 90.0% and time of onset in 77.1%. There was a lower adherence regarding duration (26.1%), in 62.2% of cases, longer than recommended. There was a statistically significant association between hours of ICT professional / ICU bed (p = 0.048), dissemination of surgical antibiotic prophylaxis use guidelines (p 0.035), adherence monitoring (p 0.024), disclosing of results (p 0.015) and the period of the day when the surgery occurred (CI = 1.7 to 6.6). A total of 43 professionals from six hospitals were interviewed. More than 80% knew about and agreed with the institutional guidelines and more than 50% reported they always followed them; 37.0% of anesthesiologists and 50.0% of surgeons believed that the guidelines were almost always followed by other professionals. One surgeon reported he never followed and believed that other professionals never followed the guidelines. The main observations of the respondents were lack of discipline in the operating room and lack of dissemination of antibiotic prophylaxis use guidelines. It was suggested to the ICT to carry out training, make the guidelines broadly available, monitor and promote adherence to them. Conclusion: The number of ICT professionals/critical bed, dissemination of guidelines, monitoring and disclosing of results are associated with higher adherence regarding antibiotic prophylaxis use; period of surgery, dose (IC 1,72-6,65) and initial time (IC 1,12-3,01) and surgery type, initial time (IC 1,24-4,25) and duration (IC 1,09-2,59). The identified inadequacies seem more related to microbial resistance than with SSI. The ICT had structure as required by law, but had shortcomings regarding the process of guideline implementation, monitoring and dissemination of results. It is of the utmost importance to promote better approach to ICT, especially with the individuals involved in the surgical process as well as the search for innovative solutions, as the conventional methods of intervention are not yielding the expected results.
