OBJETIVO: mapear evidências científicas sobre a prevenção e o manejo precoce de infecção de sítio cirúrgico por telemonitoramento em pacientes cirúrgicos após alta hospitalar. MÉTODO: revisão de escopo desenvolvida conforme proposto pelo Instituto Joanna Briggs (JBI). Foi realizada a pesquisa nas bases de dados PubMed, Literatura Latino-americana e do Caribe em Ciências da Saúde (LILACS), Cochrane Collaboration, Scopus, CINAHL, MEDLINE, Web of Science e Embase. Os estudos foram adicionados ao gerenciador Endnote Basic e Rayyan por três pesquisadores independentes. RESULTADOS: foram identificados 1.386 estudos e incluídos 31, os quais apresentaram relevância em relação a sinais de alerta precoce e tardio da infecção de sítio cirúrgico, complicações, fatores de risco, prevenção e utilização do telemonitoramento. CONCLUSÃO: observou-se que, embora os estudos abordem a infecção de sítio cirúrgico e o telemonitoramento, faz-se necessário a formulação dos instrumentos utilizados nas consultas telefônicas, contemplando com maior especificidade os critérios indispensáveis a serem abordados.

OBJECTIVE: This study aims to map scientific evidence regarding the prevention and early management of surgical site infection through telemonitoring in surgical patients after discharge from the hospital. METHOD: A scoping review was conducted following the guidelines proposed by the Joanna Briggs Institute (JBI). The search was performed across PubMed, Latin American and Caribbean Health Sciences Literature (LILACS), Cochrane Collaboration, Scopus, CINAHL, MEDLINE, Web of Science, and Embase databases. Three independent researchers collect the identified studies using Endnote Basic and Rayyan. RESULTS: A total of 1,386 studies were identified, of which 31 were included in the analysis. These selected studies demonstrated significance regarding early and late warning signs of surgical site infection, complications, risk factors, prevention strategies, and the utilization of telemonitoring. CONCLUSION: While the studies address surgical site infection and telemonitoring, it is imperative to formulate the instruments employed in telephonic consultations, incorporating a more specific consideration of essential criteria to be addressed.

Microbiological profile and antibiotic sensitivity of maxillofacial infections in an emergency hospital

Aim: To investigate the bacteriological profile of oral and maxillofacial infections and the pattern of sensitivity to a specific group of antibiotics in a reference emergency hospital in Brazil. Methods: This is a prospective cohort institutional study that studied patients affected by oral and/ or maxillofacial infections in a Brazilian emergency hospital, over a 12-month period, of different etiologies, through data collection, culture and antibiogram tests, and monitoring of the process of resolution of the infectious condition. The variables were analyzed using the chi-square and Mann-Whitney tests, using a significance level of 5%. Results: The sample consisted of 61 patients, 62.3% male. The mean age of participants was 34.3 years. Odontogenic infection was the most frequent etiology and the submandibular space was the most affected. The bacterial species Streptococcus viridans was isolated in 21.6% of cases. Levofloxacin, vancomycin and penicillin were the antibiotics with the highest frequency of bacterial sensitivity, while clindamycin and erythromycin showed the highest percentages of resistance. Conclusions: The results suggest that, among the most used antibiotics for the treatment of these infections, penicillin remains an excellent option of choice for empirical therapy

Removal Rate of the Tomofix® System after High Tibial Osteotomy is Higher Than Reported / A taxa de remoção do sistema Tomofix® após a osteotomia tibial alta é superior à relatada

Abstract Objective Medial open wedge high tibial osteotomy (MOWHTO) significantly relieves pain in the medial joint line in medial compartment osteoarthritis of the knee. But some patients complain of pain over the pes anserinus even 1 year after the osteotomy, which may require implant removal for relief. This study aims to define the implant removal rate after MOWHTO due to pain over the pes anserinus. Methods One hundred and three knees of 72 patients who underwent MOWHTO for medial compartment osteoarthritis between 2010 and 2018 were enrolled in the study. Knee injury and osteoarthritis outcome score (KOOS), Oxford knee score (OKS), and visual analogue score (VAS) were assessed for pain in the medial knee joint line (VAS-MJ) preoperatively, 12 months postoperatively, and yearly thereafter; adding VAS for pain over the pes anserinus (VAS-PA). Patients with VAS-PA ≥ 40 and adequate bony consolidation after 12 months were recommended implant removal. Results Thirty-three (45.8%) of the patients were male and 39 (54.2%) were female. The mean age was 49.4 ± 8.0 and the mean body mass index was 27.0 ± 2.9. The Tomofix medial tibial plate-screw system (DePuy Synthes, Raynham, MA, USA) was used in all cases. Three (2.8%) cases with delayed union requiring revision were excluded. The KOOS, OKS, and VAS-MJ significantly improved 12 months after MOWHTO. The mean VAS-PA was 38.3 ± 23.9. Implant removal for pain relief was needed in 65 (63.1%) of the103 knees. The mean VAS-PA decreased to 4.5 ± 5.6 3 months after implant removal (p < 0.0001). Conclusion Over 60% of the patients may need implant removal to relieve pain over the pes anserinus after MOWHTO. Candidates for MOWHTO should be informed about this complication and its solution.

Resumo Objetivo A osteotomia tibial alta com cunha de abertura medial (MOWHTO, do inglês medial open wedge high tibial osteotomy) alivia de forma significativa a dor na linha articular medial em casos de osteoartrite do compartimento medial do joelho. Alguns pacientes, porém, se queixam de dor nos tendões dos músculos sartório, grácil e semitendinoso (pata de ganso) mesmo 1 ano após a osteotomia, o que pode exigir a remoção do implante. Este estudo define a taxa de remoção do implante após a MOWHTO devido à dor nos tendões dos músculos sartório, grácil e semitendinoso. Métodos Cento e três joelhos de 72 pacientes submetidos à MOWHTO para tratamento da osteoartrite do compartimento medial entre 2010 e 2018 foram incluídos no estudo. A pontuação de desfecho de lesão no joelho e osteoartrite (KOOS, do inglês Knee Injury and Osteoarthritis Outcome Score), a pontuação dejoelho de Oxford (OKS, do inglês Oxford Knee Score) e a escala visual analógica (EVA) de dor na linha articular medial do joelho (EVA-MJ) foram avaliados antes da cirurgia. A EVA nos tendões dos músculos sartório, grácil e semitendinoso (EVA-PA) foi adicionada a essas avaliações, também realizadas 12 meses após o procedimento e, a seguir, anualmente. A remoção do implante foi recomendada em pacientes com EVA-PA ≥ 40 e consolidação óssea adequada em 12 meses. Resultados Trinta e três (45,8%) pacientes eram homens e 39 (54,2%), mulheres. A média de idade foi de 49,4 ±8,0, e o índice de massa corpórea (IMC) médio foi de 27,0 ± 2,9. O sistema placa-parafuso tibial medial Tomofix (DePuy Synthes, Raynham, MA, EUA) foi utilizado em todos os casos. Três (2,8%) casos foram excluídos devido ao retardo de consolidação e à necessidade de revisão. Os resultados nas escalas KOOS, OKS e EVA-MJ melhoraram significativamente 12 meses após a MOWHTO. A EVA-PA média foi de 38,3 ± 23,9. A remoção do implante para alívio da dor foi necessária em 65 (63,1%) dos 103 joelhos. Três meses após a remoção do implante, a EVA-PA média diminuiu para 4,5 ± 5,6 (p < 0,0001). Conclusão A remoção do implante pode ser necessária em mais de 60% dos pacientes para alívio da dor nos tendões dos músculos sartório, grácil e semitendinoso após a MOWHTO. Os candidatos à MOWHTO devem ser informados sobre esta complicação e sua resolução.

Prevalencia y análisis de factores de infección de sitio quirúrgico en clínica de heridas / Prevalence and Analysis of Surgical Site Infection Factors in Wound Clinic

Introducción: La infección de herida quirúrgica causa altas tasas de morbilidad y repercute sobre los índices de mortalidad. Constituye la primera infección intrahospitalaria entre pacientes quirúrgicos del total de infecciones nosocomiales y la primera entre los pacientes quirúrgicos. Existen factores de riesgo como la clasificación ASA, la diabetes mellitus, la hipertensión arterial y los días de estancia hospitalaria, los cuales influyen en su desarrollo. Objetivo: Determinar la prevalencia de infecciones de sitio quirúrgico por cirugías realizadas en el Hospital Dr. Carlos Canseco de Tampico, ciudad del estado mexicano de Tamaulipas. Métodos: Diseño observacional, analítico, transversal y retrospectivo de 54 pacientes con diagnóstico de infección de sitio quirúrgico. Las variables de estudio se clasificaron como dependientes (género, edad, lugar de origen, días de estancia hospitalaria, peso, índice de masa corporal) e independientes (diagnóstico, procedimiento quirúrgico realizado y clasificación ASA otorgada). Resultados: La población de 40 a 50 años fue la más afectada, con mayor predominancia sobre el género femenino. La Clasificación ASA II y III presentaron mayor prevalencia de infección de sitio quirúrgico, sobre todo en cirugías electivas (28 por ciento). Mientras mayor fue la estancia hospitalaria, mayor fue la probabilidad de desarrollar infección de sitio quirúrgico. Conclusiones: La prevalencia de infección en el sitio quirúrgico en pacientes operados por los distintos servicios quirúrgicos no es similar a la reportada por otros autores. La Clasificación ASA II y III presentaron infección del sitio quirúrgico con más frecuencia, mientras que la comorbilidad más llamativa de este estudio fue el índice de masa corporal como factor de riesgo que no debe pasar desapercibido(AU)

Introduction: Surgical wound infection causes high morbidity rates and impacts mortality rates. It is the first in-hospital infection among surgical patients of all nosocomial infections and the first among surgical patients. There are risk factors that influence its development, such as the ASA classification, diabetes mellitus, arterial hypertension and days of hospital stay. Objective: To determine the prevalence of surgical site infections from surgeries performed at Hospital Dr. Carlos Canseco, of Tampico, a city in the Mexican state of Tamaulipas. Methods: An observational, analytical, cross-sectional and retrospective study was carried out with 54 patients with a diagnosis of surgical site infection. The study variables were classified as dependent variables (gender, age, place of origin, days of hospital stay, weight and body mass index) and independent variables (diagnosis, surgical procedure performed, and given ASA classification). Results: The population aged 40 to 50 years was the most affected, with a greater predominance of the female gender. ASA classification II and III had a higher prevalence of surgical site infection, above all in elective surgeries (28 %). The longer the hospital stay, the higher the probability of developing surgical site infection. Conclusions: The prevalence of surgical site infection in patients operated on by the different surgical services is not similar to that reported by other authors. ASA Classification II and III presented surgical site infection more frequently, while the most remarkable comorbidity in this study was body mass index as a risk factor that should not go unnoticed(AU)

Risk factors associated with surgical site infection in patients with musculoskeletal cancer / Fatores de risco associados à infecção de sítio cirúrgico em portadores de câncer musculoesquelético / Factores de riesgo asociados a la infección del sitio quirúrgico en pacientes con cáncer musculoesquelético

Background and objectives: surgical site infections (SSI) continue to be a major concern in orthopedic oncology and pose as great a challenge as cancer recurrence, despite the preventive potential of surgery. SSI can be avoided if evidence-based measures are taken. The objective was to assess the frequency of infections in oncological orthopedic surgeries and associated risk factors and inflammatory markers in a reference hospital in the state of Pernambuco. Methods: the frequency of SSI, the identification of isolated microorganisms, the risk factors and the profile of Th1 and Th2 inflammatory markers (IL-2, IL-4, IL-6, IL-10, TNF and IFN-Ƴ) in patients with musculoskeletal cancer were analyzed. Results: SSI were found in 9.1% of patients undergoing orthopedic surgery. Bivariate analysis revealed that a surgical team comprising more than five members (p=0.041) and the need for intraoperative transfusion (p=0.012) were correlated with a higher risk of SSI. The measurement of ultrasensitive C-reactive protein levels to assess the inflammatory response after SSI showed results that were superior to the reference values for each sample, ranging from >5 to >200mg/dl by the immunoturbidimetric method. Of the IL-2, INFγ and TNF (Th1) and IL-4, IL-6, IL-10 (Th2) levels, only interleukin 6 showed high levels, between 6.68 and 58.76 pg/mL. Conclusion: the study found that surgical team with five or more members and blood transfusion were factors associated with the development of SSI in orthopedic surgery in patients with musculoskeletal cancer. Among the inflammatory markers, interleukin 6 (IL-6) showed the highest correlation with the outcome.(AU)

Justificativa e objetivos: as infecções do sítio cirúrgico (ISC) continuam sendo uma grande preocupação na oncologia ortopédica e representam um desafio tão grande quanto a recorrência do câncer, apesar do potencial preventivo da cirurgia. As ISC podem ser evitadas se forem tomadas medidas baseadas em evidências. O objetivo foi avaliar a frequência de infecções em cirurgias ortopédicas oncológicas e os fatores de risco e marcadores inflamatórios associados em um hospital de referência no estado de Pernambuco. Métodos: foram analisados a frequência de ISC, a identificação de microrganismos isolados, os fatores de risco e o perfil de marcadores inflamatórios Th1 e Th2 (IL-2, IL-4, IL-6, IL-10, TNF e IFN-Ƴ) em pacientes portadores de câncer musculoesquelético. Resultados: as ISC foram encontradas em 9,1% dos pacientes submetidos à cirurgia ortopédica. A análise bivariada revelou que uma equipe cirúrgica composta por mais de cinco membros (p=0,041) e a necessidade de transfusão intraoperatória (p=0,012) foram correlacionadas com maior risco de ISC. A dosagem dos níveis de proteína C reativa ultrassensível para avaliação da resposta inflamatória após ISC apresentou resultados superiores aos valores de referência para cada amostra, variando de >5 a >200mg/dl pelo método imunoturbidimétrico. Dos níveis de IL-2, INFγ e TNF (Th1) e IL-4, IL-6, IL-10 (Th2), apenas a interleucina 6 apresentou níveis elevados, entre 6,68 e 58,76 pg/mL. Conclusão: o estudo constatou que equipe cirúrgica com cinco ou mais membros e transfusão sanguínea foram fatores associados ao desenvolvimento de ISC em cirurgia ortopédica em pacientes com câncer musculoesquelético. Entre os marcadores inflamatórios, interleucina 6 (IL-6) apresentou maior correlação com o desfecho.(AU)

Justificación y objetivos: las infecciones del sitio quirúrgico (ISQ) siguen siendo una preocupación importante en la oncología ortopédica y representan un desafío tan grande como la recurrencia del cáncer, a pesar del potencial preventivo de la cirugía. Las ISQ se pueden prevenir si se toman medidas basadas en la evidencia. El objetivo fue evaluar la frecuencia de infecciones en cirugías ortopédicas oncológicas y los factores de riesgo y marcadores inflamatorios asociados en un hospital de referencia en el estado de Pernambuco.

Resultados: se encontraron ISQ en el 9,1% de los pacientes sometidos a cirugía ortopédica. El análisis bivariado reveló que un equipo quirúrgico compuesto por más de cinco miembros (p=0,041) y la necesidad de transfusión intraoperatoria (p=0,012) se correlacionaron con un mayor riesgo de ISQ. La medición de los niveles de proteína C reactiva ultrasensible para evaluar la respuesta inflamatoria después de la ISQ presentó resultados superiores a los valores de referencia para cada muestra, variando de >5 a >200 mg/dl por el método inmunoturbidimétrico. De los niveles de IL-2, INFγ y TNF (Th1) e IL-4, IL-6, IL-10 (Th2), solo la interleucina 6 mostró niveles elevados, entre 6,68 y 58,76 pg/mL. Conclusión: el estudio encontró que el equipo quirúrgico con cinco o más miembros y la transfusión el estudio encontró que un equipo quirúrgico con cinco o más miembros y transfusión de sangre fueron factores asociados con el desarrollo de ISQ en cirugía ortopédica en pacientes con cáncer musculoesquelético. Entre los marcadores inflamatorios, la interleucina 6 (IL-6) mostró la mayor correlación con el resultado.(AU)

Regional analgesia and surgical site infections after colorectal surgery: a retrospective cohort analysis

Abstract Background The effect of regional analgesia on perioperative infectious complications remains unknown. We therefore tested the hypothesis that a composite of serious infections after colorectal surgery is less common in patients with regional analgesia than in those given Intravenous Patient-Controlled Analgesia (IV-PCA) with opiates. Methods Patients undergoing elective colorectal surgery lasting one hour or more under general anesthesia at the Cleveland Clinic Main Campus between 2009 and 2015 were included in this retrospective analysis. Exposures were defined as regional postoperative analgesia with epidurals or Transversus Abdominis Plane blocks (TAP); or IV-PCA with opiates only. The outcome was defined as a composite of in-hospital serious infections, including intraabdominal abscess, pelvic abscess, deep or organ-space Surgical Site Infection (SSI), clostridium difficile, pneumonia, or sepsis. Logistic regression model adjusted for the imbalanced potential confounding factors among the subset of matched surgeries was used to report the odds ratios along with 95% confidence limits. The significance criterion was p < 0.05. Results A total of 7811 patients met inclusion and exclusion criteria of which we successfully matched 681 regional anesthesia patients to 2862 IV-PCA only patients based on propensity scores derived from potential confounding factors. There were 82 (12%) in-hospital postoperative serious infections in the regional analgesia group vs. 285 (10%) in IV-PCA patients. Regional analgesia was not significantly associated with serious infection (odds ratio: 1.14; 95% Confidence Interval 0.87‒1.49; p-value = 0.339) after adjusting for surgical duration and volume of intraoperative crystalloids. Conclusion Regional analgesia should not be selected as postoperative analgesic technique to reduce infections.

Abstract Objective This study assessed the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of serological tests, synovial fluid markers, microbiological tissue culture, and histopathological examination of the periprosthetic membrane in diagnosing periprosthetic knee infection. Methods This study is prospective, and it includes patients undergoing total knee arthroplasty revision surgery from November 2019 to December 2021. The analysis consisted of serological tests (erythrocyte sedimentation rate [ESR], C-reactive protein [CRP], and D-dimer), synovial fluid markers (leukocyte and polymorphonuclear cell counts), periprosthetic tissue culture, and histopathological examination of the periprosthetic membrane of all patients. Results Sixty-two patients had periprosthetic joint infection (PJI) according to the 2018 International Consensus Meeting criteria (infection group), while 22 subjects had no infection. ESR sensitivity and specificity were 83.6% and 45.4%, respectively. CRP sensitivity and specificity were 64.5% and 100%, whereas D-dimer sensitivity and specificity were 78.9% and 25%, respectively. Leukocyte count sensitivity and specificity were 75.6% and 100%, polymorphonuclear cell count sensitivity and specificity were 33% and 100%, respectively. Periprosthetic tissue culture sensitivity and specificity culture were, respectively, 77.4% and 100%. Histopathological examination sensitivity and specificity were 43.7% and 100%, respectively. Conclusions In our study, the total blood cell count in synovial fluid and microbiological cultures of periprosthetic tissues were the most accurate tests for PJI diagnosis. In contrast, polymorphonuclear cell percentage was the least accurate test for PJI diagnosis.

Accuracy of Hip Pericapsular Nerve Block (PENG) without Ultrasound Aid in Patients with Hip Pain / Acurácia do bloqueio dos nervos pericapsulares (PENG) do quadril sem auxílio de ultrassonografia em pacientes com dor no quadril

Abstract Objective To describe and evaluate the accuracy of the pericapsular nerve group (PENG) block technique with no ultrasound guidance. Method Series of 40 infiltrations in patients with hip pain undergoing outpatient follow-up in the hip surgery group or admitted to the emergency room from a hospital in São Paulo, SP, Brazil. The hip PENG technique was guided by palpable anatomical pelvic structures, with no ultrasound orientation for needle positioning, using the equipment only to check the correct location after an unguided puncture. Results In the 40 hips infiltrated from 35 patients with a mean age of 59.2 years, the success rate was 85%. Among the mispositioned cases, 71.4% occurred in the first 13 applications and 28.6% in the subsequent 27 applications. In all patients, the neurovascular bundle was in the medial third of the pen-made demarcation. Even in cases with a failed needle location, the distance from the neurovascular bundle was safe. A single adverse effect occurred, with spontaneous improvement of the femoral nerve apraxia within two days. Conclusion Unguided PENG block is a viable technique for a physician knowledgeable about its application in services with no ultrasound availability.

Resumo Objetivo Descrever e avaliar a acurácia da técnica do bloqueio PENG realizado sem auxílio de ultrassonografia. Método Série de 40 infiltrações em pacientes com dor no quadril, em acompanhamento ambulatorial no grupo de cirurgia do quadril ou admitidos no pronto atendimento de um hospital na cidade de São Paulo. Utilizada a técnica de bloqueio nervoso pericapsular do quadril (PENG) guiado por estruturas anatômicas palpáveis da pelve e sem auxílio de ultrassonografia no posicionamento da agulha, usando o aparelho apenas para conferência da localização correta após punção não guiada. Resultados Nos 40 quadris infiltrados em 35 pacientes com idade média de 59,2 anos, obtivemos um índice de acerto de 85%. Dos casos mal posicionados 71,4% ocorreram nas primeiras 13 aplicações e 28,6% nas 27 aplicações subsequentes. Em todos os pacientes o feixe neurovascular estava situado no terço medial da marcação realizada à caneta e mesmo nos casos em que houve falha da localização da agulha havia distância segura ao feixe neurovascular. Obtivemos apenas 1 caso de efeito adverso, onde ocorreu apraxia do nervo femoral com melhora espontânea em 2 dias. Conclusão O bloqueio PENG não guiado é uma técnica viável e pode ser realizada por um médico que já possui conhecimento na aplicação, em serviços onde não haja disponibilidade do aparelho de ultrassonografia.

Esta investigación busca explorar los beneficios del cierre primario diferido en la reducción de infecciones, estancia hospitalaria y costos, mejorando los resultados clínicos en cirugías abdominales. Objetivos. Evaluar el cierre primario diferido en pacientes laparotomizados de emergencia que acuden Hospital Universitario de Mérida ­Venezuela, con índice SENIC ≥ 3 puntos. Métodos. Se llevó a cabo un estudio experimental prospectivo para evaluar los efectos del cierre primario diferido en comparación con el cierre primario en laparotomías exploradoras. La muestra consistió en 160 pacientes. Se analizaron la presencia de infecciones, la duración de la estancia hospitalaria y la evolución temporal de las infecciones como desenlaces del estudio. Resultados. Se encontró que el cierre primario diferido redujo la presencia de infecciones en comparación con el cierre primario. La limpieza trans-operatoria y el diagnóstico de abdomen agudo quirúrgico infeccioso fueron factores beneficiosos. La antibioticoterapia continua en el postoperatorio también fue más efectiva. Se observó una disminución del riesgo de infección en el grupo experimental en un 37% en comparación con el grupo de control. Conclusiones. El cierre primario diferido de la herida reduce significativamente la probabilidad de infección del sitio operatorio en cirugías abdominales con heridas contaminadas. Es una técnica beneficiosa para pacientes con abdomen agudo quirúrgico infeccioso. Además, el cierre primario diferido resulta rentable al disminuir tanto la incidencia de ISO como la duración de la estancia hospitalaria

Surgical site infections pose a challenge in the hospital setting. Delayed primary closure has emerged as a technique to prevent such infections. This research aims to explore the benefits of delayed primary closure in reducing infections, hospital stay, and costs, thus improving clinical outcomes in abdominal surgeries. Objectives. To evaluate delayed primary closure in emergency laparotomized patients with SENIC index ≥ 3 points at the University Hospital of Mérida, Venezuela. Methods. A prospective experimental study was conducted to assess the effects of delayed primary closure compared to primary closure in exploratory laparotomies. The sample consisted of 160 patients. The presence of infections, duration of hospital stay, and temporal evolution of infections were analyzed as study outcomes. Results. Delayed primary closure was found to reduce the presence of infections compared to primary closure. Transoperative cleaning and the diagnosis of infectious surgical acute abdomen were beneficial factors. Continuous postoperative antibiotic therapy was also more effective. A 37% reduction in the risk of infection was observed in the experimental group compared to the control group. Conclusions. Delayed primary closure significantly reduces the probability of surgical site infection in abdominal surgeries with contaminated wounds. It is a beneficial technique for patients with infectious surgical acute abdomen. Additionally, delayed primary closure proves cost-effective by reducing both the incidence of surgical site infections and the duration of hospital stay(AU)

Patient participation in surgical site infection prevention: perceptions of nurses, physicians and patients / Participación del paciente en la prevención de la infección del sitio quirúrgico: percepciones de enfermeras, médicos y pacientes / Participação do paciente na prevenção de infecção do sítio cirúrgico: percepções de enfermeiros, médicos e pacientes

ABSTRACT Objective: To analyze the perception of patients and health professionals regarding patients' participation in surgical site infection prevention. Methods: Cross-sectional study conducted in two hospitals in the city of São Paulo, with a convenience sample of 123 patients in the postoperative period of elective surgeries and 92 health professionals (physicians and nurses) acting in direct care of surgical patients. Results: Patients (78.9%) and professionals (79.4%) fully agreed with the importance of patient participation to prevent surgical site infection. The impact of patient participation on infection rates was significant for those undergoing previous surgery (p = 0.021).

The burden of healthcare-associated infection in Moroccan hospitals: systematic review and meta-analysis

Healthcare-associated infections (HAI), also referred to as nosocomial infections, is defined as an infection acquired in a hospital setting. This infection is considered a HAI if it was not present or incubating at the time of admission. This includes infections acquired in the hospital but appearing after discharge, and also occupational infections among staff of the facility. HAI are a major patient safety measure to be considered in hospitals.

Surgical Site Infection (SSI) Rate after Colorectal surgery at the Philippine General Hospital

OBJECTIVE@#Surgical site infection (SSI) is one of the most common healthcare-associated infections. This study aimed to determine SSI rate and the associated factors among colorectal surgery patients.@*METHODS@#This included adult patients who underwent surgery under the Division of Colorectal Surgery from January to May 2018. Clinico-demographic, operative, and SSI outcome data were reviewed. Occurrence of SSI during admission until discharge, and up to 30 days after the surgery was analyzed. @*RESULTS@#A total of 172 surgeries were performed. Majority were elective procedures (68.0%), and performed via open approach (67.4%). Most were malignant cases (62.6%). Sixty-three colorectal resections were done (41 colon and 22 rectal). SSI rate prior to discharge was 6.4%, and 15.7% at 30 days. Among colorectal resections, 18 (28.6%) patients had SSI at 30 days. SSI rates were significantly higher among patients who were ASA 2 or 3; received chemotherapy 12 weeks prior to surgery; had malignant pathology; underwent emergency surgery; received perioperative transfusion; had stapled skin closure; had low anterior resection for rectal cancer; and had multivisceral resection. @*CONCLUSION@#The Division of Colorectal Surgery at the Philippine General Hospital had a higher SSI rate as compared to literature. Although this could be partly explained by the differences in patient and surgeon population, improving on SSI rates will be the unit's goal. Continued SSI surveillance with more patient accrual may provide better insight to the associated risk factors.

Elective incisional hernia repair: lower risk of postoperative wound infection with laparoscopic versus open repair

INTRODUCTION@#The superiority of laparoscopic repair over open repair of incisional hernias (IHs) in the elective setting is still controversial. Our study aimed to compare the postoperative outcomes of laparoscopic and open elective IH repair in an Asian population.@*METHODS@#This retrospective study was conducted in an acute general hospital in Singapore between 2010 and 2015. Inclusion criteria were IH repair in an elective setting, IHs with diameter of 3-15 cm, and location at the ventral abdominal wall. We excluded patients who underwent emergency repair, had recurrent hernias or had loss of abdominal wall domain (i.e. hernia sac containing more than 30% of abdominal contents or any solid organs). Postoperative outcomes within a year such as recurrence, pain, infection, haematoma and seroma formation were compared between the two groups.@*RESULTS@#There were 174 eligible patients. The majority were elderly Chinese women who were overweight. Open repair was performed in 49.4% of patients, while 50.6% underwent laparoscopic repair. The mean operation time for open repair was 116 minutes (116 ± 60.6 minutes) and 139 minutes (136 ± 64.1 minutes) for laparoscopic repair (P = 0.079). Within a year after open repair, postoperative wound infection occurred in 15.1% of the patients in the open repair group compared to 1.1% in the laparoscopic group (P = 0.0007). Postoperative pain, recurrence and haematoma/seroma formation were comparable.@*CONCLUSION@#Elective laparoscopic IH repair has comparable outcomes with open repair and may offer the advantage of reduced postoperative wound infection rates.

Chinese Medicine Plaster as A New Treatment for Surgical Site Infection in Patients with Cesarean Delivery: A Randomized, Double-Blind, Controlled Trial / 中国结合医学杂志

OBJECTIVE@#To evaluate the efficacy of Chinese plaster containing rhubarb and mirabilite on surgical site infection (SSI) in patients with cesarean delivery (CD) by performing a randomized controlled trial.@*METHODS@#This randomized controlled trial included 560 patients with CD due to fetal head descent enrolled at a tertiary teaching center between December 31, 2018 and October 31, 2021. Eligible patients were randomly assigned to a Chinese medicine (CM) group (280 cases) or a placebo group (280 cases) by a random number table, and were treated with CM plaster (made by rhubarb and mirabilite) or a placebo plaster, respectively. Both courses of treatment lasted from the day 1 of CD, followed day 2 until discharge. The primary outcome was the total number of patients with superficial, deep and organ/space SSI. The secondary outcome was duration of postoperative hospital stay, antibiotic intake, and unplanned readmission or reoperation due to SSI. All reported efficacy and safety outcomes were confirmed by a central adjudication committee that was unaware of the study-group assignments.@*RESULTS@#During the recovery process after CD, the rates of localized swelling, redness and heat were significantly lower in the CM group than in the placebo group [7.55% (20/265) vs. 17.21% (47/274), P<0.01]. The durution of postoperative antibiotic intake was shorter in the CM group than in the placebo group (P<0.01). The duration of postoperative hospital stay was significantly shorter in the CM group than in the placebo group (5.49 ± 2.68 days vs. 8.96 ± 2.35 days, P<0.01). The rate of postoperative C-reactive protein elevation (≽100 mg/L) was lower in the CM group than in the placebo group [27.6% (73/265) vs. 43.8% (120/274), P<0.01]. However, there was no difference in purulent drainage rate from incision and superficial opening of incision between the two groups. No intestinal reactions and skin allergies were found in the CM group.@*CONCLUSIONS@#CM plaster containing rhubarb and mirabilite had an effect on SSI. It is safe for mothers and imposes lower economic and mental burdens on patients undergoing CD. (Registration No. ChiCTR2100054626).
