Incidencia de infección de localización quirúrgica en cirugía de colon y adecuación de la profilaxis antibiótica: estudio de cohortes prospectivo / Incidence of surgical site infection in colon surgery and antibiotic prophylaxis adequacy: prospective cohort study

Fundamento: La infección de localización quirúrgica (ILQ) tiene un considerable impacto clínico y económico a nivel hospitalario, por lo que se consideran prioritarios su prevención y seguimiento. El objetivo de este estudio fue la evaluación del cumplimiento del protocolo de profilaxis antibiótica en la cirugía de colon y el efecto de su inadecuación en la incidencia de ILQ. Material y métodos: Se realizó un estudio de cohortes prospectivo desde julio de 2008 a julio de 2016. Se evaluó el grado de cumplimiento de la profilaxis antibiótica y las causas de incumplimiento en cirugía de colon: duración e inicio, elección, vía de administración y dosis de antibiótico. Se estudió la incidencia de ILQ después de un período máximo de incubación de 30 días. Para evaluar el efecto del incumplimiento de la profilaxis en la ILQ se usó el riesgo relativo (RR). Resultados: El estudio incluyó 771 pacientes. La incidencia acumulada de ILQ fue del 5,8%, la mayoría (67%) infecciones incisionales superficiales. La etiología más frecuente de ILQ fue Escherichia coli (28%). La profilaxis antibiótica se administró en el 97,8% de los pacientes, con un cumplimiento global del protocolo del 91,9%. La causa principal de incumplimiento fue la elección del antibiótico (58,2%). No se encontró relación entre inadecuación de la profilaxis e incidencia de infección de localización quirúrgica (RR=0,5; IC95% 0,1-1,8). Conclusiones: La tasa global de adecuación al protocolo de profilaxis antibiótica fue alta. No se encontró asociación significativa entre adecuación de la profilaxis e incidencia de ILQ en cirugía de colo (AU)

Background: Surgical site infection (SSI) has a considerable clinical and economic impact at the hospital level, so prevention and monitoring are considered a high priority. The objective of this study was to assess compliance with the protocol of antibiotic prophylaxis in colon surgery and the effect of its inadequacy for the incidence of SSI. Methods: Prospective cohort study from July 2008 to July 2016. Compliance with antibiotic prophylaxis protocol and the causes of non-compliance were evaluated in colon surgery: duration and starting, choice, route of administration and dose of the antibiotic. The incidence of SSI was studied after a maximum incubation period of 30 days. Relative risk (RR) was used to evaluate the non-compliance causes of prophylaxis. Results: The study included 771 patients. The cumulative incidence of SSI was 5.8% (n=45), of which 2/3 were superficial incisional infections. The most common cause of SSI was Escherichia coli (28%). Antibiotic prophylaxis was administered in 97.8% of patients, with an overall protocol compliance of 91.9%. The principle cause of non-compliance was the choice of antibiotic (58.2%). No relationship between the inadequacy of prophylaxis and incidence of surgical site infection was found (RR=0.5; CI95% 0.1-1.8). Conclusions: The overall adequacy rate to antibiotic prophylaxis protocol was high. No significant association between the adequacy of prophylaxis and incidence of surgical site infection in colon surgery was foun (AU)

[Assessment of antibiotic prophylaxis adequacy in rectal surgery]. / Evaluación de la adecuación de la profilaxis antibiótica en la cirugía de recto.

OBJECTIVE: Antibiotic prophylaxis is the most suitable tool for preventing surgical site infection (SSI), so the development of guidelines and assessment of its monitoring is essential. In this study protocol compliance of antibiotic prophylaxis in rectal surgery and the effect of its adequacy in terms of pre-ention of SSI was assessed. METHODS: Prospective cohort study was conducted from 1 January 2009 to 30 December 2015. The degree of compliance with antibiotic prophylaxis and causes of non-compliance in rectal surgery was evaluated. The incidence of SSI was studied after a maximum period of 30 days of incubation. To assess the effect of prophylaxis non-compliance on SSI the relative risk (RR) adjusted with the aid of a logistic regression model was used. RESULTS: The study covered a total of 244 patients. The patients infected reached 20 cases with a SSI cumulative incidence of 8.2% (CI95%: 4.8-11.6). Antibiotic prophylaxis was indicated in all patients and was administered in 98% of cases, with an overall protocol compliance 92.5%. The principal cause of non-compliance was the choice of antibiotic 55.6% (n=10). The effect of inadequacy of antibiotic prophylaxis on surgical infection was RR=0.58, CI95%: 0.10-4.10 (P>0.05). CONCLUSIONS: Compliance with antibiotic prophylaxis was high. No relationship between the adequacy of prophylaxis and incidence of surgical site infection in rectal surgery was found.

Objetivo. Hay varios métodos para determinar hemoglobina glucosilada A1c (HbA1c), tanto rápidos para punto de uso en la consulta como de laboratorio. Nuestro objetivo ha sido comparar la concordancia diagnóstica entre 2 métodos de detección de HbA1c. Material y métodos. Se realizó un estudio descriptivo transversal de concordancia diagnóstica en el Centro de Salud Los Cármenes. Se incluyeron de forma consecutiva 2 grupos de pacientes con y sin diabetes mellitus tipo 2. Se compararon un método en punto de uso para consulta externa (DCATM Systems Siemens®) con otro de laboratorio (análisis cromatográfico). Se estudiaron la concentración de HbA1c y la concordancia entre los métodos con el coeficiente de correlación intraclase (CCI, A1) y con el método de Bland-Altman. Resultados. Se estudió a 102 pacientes, 62 diabéticos (60,8%) y 40 no diabéticos (39,2%). La media global ± desviación estándar de porcentaje de HbA1c fue de 6,46 ± 0,88 en el análisis con sangre capilar mediante sistema DCA(TM) y de 6,44 ± = 0,86 en el análisis del laboratorio (p > 0,05). El grado de acuerdo entre las 2 pruebas fue de 0,975 (intervalo de confianza del 95%, 0,963-0,983). La media de la diferencia entre las determinaciones de las 2 pruebas evaluadas fue de 0,024 ± 0,27. El porcentaje de puntos fuera de los límites de acuerdo óptimo definidos en el gráfico de Bland-Altman fue del 2,5%. Conclusiones. La concordancia diagnóstica entre un método para punto de uso en consulta y uno de laboratorio ha sido muy alta. La detección en punto de uso permite una rápida y sencilla valoración de la concentración de HbA1c (AU)

Objective. Several methods are available for measuring glycosylated A1c hemoglobin (HbA1c), all rapid methods for point of care use in a clinical or laboratory setting. This study attempts to compare the diagnostic agreement between two methods for detection of HbA1c. Material and methods. A descriptive cross-sectional study of diagnostic agreement was carried out in the Los Carmenes Health Centre. Two groups of patients -with and without type 2 diabetes- were consecutively included. A method for point-of-care use in a Primary Care Clinic setting (DCATM Systems Siemens®) was compared with a laboratory test (chromatographic analysis). An analysis was made of the mean concentration of HbA1c, the agreement between methods, using the intra-class correlation coefficient (CCLA1) and the Bland-Altman method. Results. A total of 102 patients were included, 62 diabetic (60.8%) and 40 non-diabetic (39.2%). The overall mean HbA1c was 6.46% (SD = 0.88) in the analysis using capillary blood in the clinic with the DCA(TM) system, and 6.44% (SD = 0.86) using the laboratory test (P>.05). The degree of agreement between the two tests was 0.975 (95% CI: 0.963-0.983). The mean of the differences between the results of the two assessed tests was 0.024 (SD = 0.27). The percentage of points outside the limits of optimal agreement, as defined in the Bland-Altman graph, was 2.5%. Conclusions. Diagnostic agreement between a method for point-of-care use in a Primary Health Care Clinic and a laboratory test was very high. Detection at the point-of-care allows a quick and simple assessment of HbA1c (AU)

Laparoscopic colectomy for transverse colon carcinoma: a surgical challenge but oncologically feasible.

AIM: The aim of the study was to assess the safety and feasibility of laparoscopic surgery for transverse colon cancer and to compare the clinicopathological outcome with that of conventional open surgery. METHOD: From March 1998 to December 2009, 1253 patients with colorectal tumours were operated on, 564 laparoscopically. There were 154 cases of transverse colon cancer, 86 of which were included in the study. Details were collected on age, sex, body mass index (BMI), operation time, blood loss, time to first flatus, time to resume a liquid diet, postoperative length of hospital stay, complications, TNM stage, tumour size, distal resection margin, proximal resection margin, number of nodes harvested and surgical procedure. Laparoscopic and open surgical removal was compared. RESULTS: No significant differences were found between laparoscopic and conventional groups in age, sex, BMI, operation time or postoperative length of hospital stay. The mean blood loss during the operations was significantly less in the laparoscopic group (105.9 ± 140.9 ml vs 305.7 ± 325.3 ml; P = 0.05). The time to the first flatus was shorter (2.1 ± 0.3 days vs 3.8 ± 3.0 days; P = 0.043) and diet was started earlier (3.1 ± 1.4 days vs 3.4 ± 1.5 days) in the laparoscopic group. No significant differences in tumour size, proximal resection margin or number of lymph nodes were observed. The mean distal resection margin was not statistically different (10.3 ± 4.5 cm vs 8.8 ± 4.9 cm). At a mean follow up of 33 ± 2.3 months, nonport-site metastases occurred in eight patients and locoregional recurrence occurred in three, with no significant difference between the groups. The 3-year cumulative overall survival rate was 78%, and the disease-free survival rate was 69%. CONCLUSION: There was no difference in the outcome of laparoscopic and open surgery for transverse colon cancer, including the cancer-specific outcome.
