Introdução: A profilaxia antimicrobiana cirúrgica tem se demonstrado como uma das mais importantes medidas para redução das infecções de sítio cirúrgico. O momento da administração dessa profilaxia é essencial para atingir concentrações terapêuticas nos tecidos durante o procedimento cirúrgico, condição freqüentemente não observada. O objetivo deste estudo foi caracterizar o lapso de tempo transcorrido entre a profilaxia antimicrobiana e o início da incisão cirúrgica. Métodos: Amostra de procedimentos cirúrgicos eletivos realizados em um hospital geral acompanhada mediante observação direta do momento de administração da antibioticoprofilaxia e da incisão. Resultados: Foram analisados 130 procedimentos. A maioria dos pacientes da amostra era do sexo feminino (64,6%). Em 60% dos procedimentos avaliados, os pacientes internaram no mesmo dia da cirurgia e o antimicrobiano mais utilizado foi cefazolina (91,5%). O antimicrobiano profilático foi administrado com uma mediana de 8 minutos antes da incisão, sendo que em 18 (13,8%) procedimentos foi aplicado num tempo maior que 30 min e em 37 (28,5%), foi administrado após a incisão. Em apenas 13,8% a profilaxia foi administrada conforme o protocolo da instituição. As especialidades cujos procedimentos cirúrgicos apresentaram menor freqüência de adequação do horário de administração foram cirurgias plástica (4,5%), urologia (6,7) e vascular (9,1%). Conclusão: Apesar de consagrada, a administração da profilaxia em tempo adequado ainda permanece longe do ideal no nosso meio. As instituições devem adotar medidas eficazes para minimizar a inadequação desta medida. / Introduction: Antimicrobial surgical prophylaxis has been demonstrated as one of the most important steps to reduce surgical site infections. The timing of administration of prophylaxis is essential to achieve therapeutic concentrations in tissues during the surgical procedure, which is frequently not observed. The aim of this study was to characterize the lapse of time between antimicrobial prophylaxis and beginning of surgical incision. Methods: A sample of elective surgeries performed in a general hospital accompanied by direct observation of the timing of administration of antibiotic prophylaxis and the incision. Results: We analyzed 130 procedures. Most of the patients were female (64.6%). In 60% of the procedures evaluated, patients hospitalized on the same day of surgery and antimicrobial more used was cefazolin (91.5%). The antibiotic prophylaxis was administered with a median of 8 minutes before incision, and in 18 (13.8%) procedures were applied to a time longer than 30 min and 37 (28.5%) was administered after the incision. In only 13.8% prophylaxis was administered according to institutional protocol. Whose specialty surgical procedures had lower rates of appropriateness of administration time were plastic surgery (4.5%), urology (6.7) and vascular (9.1%). Conclusion: Although established, the administration of prophylaxis in a timely manner remains far from ideal in our midst. Institutions should adopt effective measures to minimize the inadequacy of this measure.

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.

Between 12% and 84% those infections are detected after the patient leaves hospital, hence the importance of post-discharge surveillance. OBJECTIVES: The post-discharge surveillance woman service implementation who underwent gynecological surgery in school hospital in Teresina - PI; monitor the occurrence of ISC and association with risk factors; characterizing the socio-demographic profile; appoint incidence rate (SSI) in gynecological ambulatory for surveillance method, and identify the profile of SSI misdiagnosed after discharge. METHODS: Prospective and quantitative study, accomplished in gynecological ambulatory in Getulio Vargas Hospital, which is for public education, and a large general hospital, and the health reference for the state of Piauí and further the North and Northeast regions of Brazil. The population was 1026 patient women which has undergone gynecological surgery in period from june 2011 to march 2013. The project was approved for the UFPI Research Ethics Committee, under the CAAE: 0059 045 000.11. RESULTS: It was used SSI epidemiologic surveillance, type active report for 30 days in gynecological ambulatory, by face or telephonic contact. Return rate of women to gynecological ambulatory was 86,6% and SSI incidence was 5,8%, those 71,1% was classed in superficial incisional and 28,3% deep incisional. The average time betwixt surgery and SSI diagnosis was 12,9 days; the highest incidence is in the age group 25-44 years (44.3%); came from the city (57,8%) e countryside of the State (42,2%), 63% married women, had basic education 61%, 46,4% declare having minimum wage. The risk factors to SSI development was: OP Time (days), neoplasm and Diabetes mellitus. CONCLUSION: Highlighted the increased incidence of SSI notification, pointing to the importance of accompanying the women in post-discharge surveillance, using a systematic strategy.

Background: The aim of surgical antibiotic prophylaxis (SAP) is to prevent surgical site infection (SSI) by administering an appropriate antimicrobial agent perioperatively. However, SAP may be associated with adverse effects and incurs added costs. The primary objective of this prospective study is to establish whether clinicians are adhering to existing perioperative antibiotic prophylaxis guidelines in terms of indication, dosage and timing of SAP. Secondary objectives are to determine the proportion of patients receiving inappropriate antibiotics; and to evaluate correct practice concerning re-dosing and duration of SAP. Methods: A cross-sectional prospective audit of the anaesthetic records and prescription charts of surgical patients was conducted at Groote Schuur Hospital, a tertiary level teaching hospital in Cape Town, South Africa, over a period of one week. Data were collected by anaesthetists – blinded to the study objectives – and the investigators; then captured on Excel spread sheets and compared to existing SAP guidelines. Descriptive statistics and binary logistic regression were used for analysis. Results: Of the 192 patients consented, 180 questionnaires were completed for data analysis. The median age of participants was 44.5 years (IQR: 31.5-58), with a preponderance of females (58.7%). SAP was administered in 149 cases (82.8%) and withheld in 31 (17.2%). This was appropriate in 91.9% (137/149) and 77.4% (24/31) respectively. Twelve patients (6.7%) received inappropriate antibiotics and in seven (3.9%) it was inappropriately withheld. Of the 156 patients who should have received SAP, choice of drug was correct in 121 (77.6%), dosage in 110 (70.5%) and timing in 87 (55.8%). Absolute compliance was achieved in 44.4% (80/180). Errors were mostly related to timing, re-dosing and duration of SAP. Conclusion: Anaesthetists and surgeons at Groote Schuur Hospital demonstrate variable adherence to surgical antibiotic prophylaxis guidelines. Interventions aimed at improving compliance are warranted.

Introduction The year 2020 marked the first year in which a match under single accreditation took place. Both osteopathic (DO) and allopathic (MD) students would participate in the first match cycle without a dedicated DO match system. Our primary objective was to investigate how single accreditation has impacted the DO applicants attempting to match into surgical specialties. Our secondary objective was to investigate the impact of single accreditation at the program director (PD) level and whether or not this process would see a change in DO PD distribution in previously American Osteopathic Association (AOA)-approved programs. Method Information on number of applicants and post-match positions was gathered from AOA and National Residency Match Program (NRMP) websites. Credentials of PDs were obtained from the Accreditation Council on Graduate Medical Education website. Based on the available data, the following surgical specialties were compared for the years 2020, 2018, and 2016: General Surgery, Neurological Surgery (NSGY), Orthopedic Surgery, Otolaryngology/ENT (ENT), Plastic Surgery, and Thoracic Surgery. Data from 2016 were not included in the results as the AOA match results analysis was insufficient and unable to be directly compared to the NRMP data. Results of matched DO and MD applicants were compared using bivariate analysis. A p-value of <0.05 was considered significant. Results From the year 2018 to 2020, the DO applicants saw a decrease of 3% in the total number of matched postgraduate year 1 spots in surgical specialties. NRMP results from 2020 saw that 51.7% of DO applicants matched and 67.7% (p < 0.001) of MD applicants matched for the specialties examined. Percent of matched:applied for DO applicants was lower than MD applicants in the fields of NSGY (p < 0.001), ENT (p < 0.001), Plastic Surgery (p < 0.001), General Surgery (p < 0.001), and Thoracic Surgery (p = 0.011). After evaluating 60 former AOA General Surgery programs, 56% were found to have MD as PD. Another 26 former AOA surgical programs were investigated, and 58% were found to have MD PD. Conclusion Single accreditation has impacted the match process now that a large number of both MD and DO applicants are using the NRMP match system for postgraduate placement. Based on the available data, our results indicate that in the examined surgical specialties, there is a statistically significant difference in the number of MD and DO residents.
