'Epidemiology of surgical site infection in a neurosurgery department'.

OBJECTIVE: To know the rates of infection of the surgical wound in the Department of Neurosurgery between 2011 and 2014. METHODS: An observational, prospective study was conducted of the rates of surgical wound infection among patients admitted for more than 48 h to the Neurosurgery Department of a tertiary-level university hospital between July 2011 and December 2014. RESULTS: The study surveyed a total of 536 surgical procedures performed in 521 patients. The rate of diagnosed surgical site infection (SSI) was 4.85% (26 infections), below the established acceptable threshold of 5%. Of these, 65.38% were organ-space infections, 30.77% deep infections, and 7.69% superficial infections. Infection rates for each type of surgical procedure were 4.35% for spinal fusion, 0.00% for refusion of spine, 2.08% for laminectomy, 5.95% for ventricular shunt, and 5.14% for craniotomy. Antibiotic prophylaxis was evaluated as suitable in 80.22% of surgical procedures. DISCUSSION AND CONCLUSIONS: Infection rates were lower when the surgery was elective, clean, the patient had a lower ASA, and when suitable antimicrobial prophylaxis was administered. The rate of suitable antimicrobial prophylaxis shows that there is room for improvement. In order to minimize the risk of surgical wound infection, all professionals involved in patient care need to know and apply current recommendations, especially those relating to proper hand hygiene and suitable antibiotic prophylaxis.

Impact of the coronavirus disease 2019 (COVID-19) pandemic on nosocomial Clostridioides difficile infection.

OBJECTIVES: The coronavirus disease 2019 (COVID-19) pandemic has induced a reinforcement of infection control measures in the hospital setting. Here, we assess the impact of the COVID-19 pandemic on the incidence of nosocomial Clostridioides difficile infection (CDI). METHODS: We retrospectively compared the incidence density (cases per 10,000 patient days) of healthcare-facility-associated (HCFA) CDI in a tertiary-care hospital in Madrid, Spain, during the maximum incidence of COVID-19 (March 11 to May 11, 2020) with the same period of the previous year (control period). We also assessed the aggregate in-hospital antibiotic use (ie, defined daily doses [DDD] per 100 occupied bed days [BD]) and incidence density (ie, movements per 1,000 patient days) of patient mobility during both periods. RESULTS: In total, 2,337 patients with reverse transcription-polymerase chain reaction-confirmed COVID-19 were admitted to the hospital during the COVID-19 period. Also, 12 HCFA CDI cases were reported at this time (incidence density, 2.68 per 10,000 patient days), whereas 34 HCFA CDI cases were identified during the control period (incidence density, 8.54 per 10,000 patient days) (P = .000257). Antibiotic consumption was slightly higher during the COVID-19 period (89.73 DDD per 100 BD) than during the control period (79.16 DDD per 100 BD). The incidence density of patient movements was 587.61 per 1,000 patient days during the control period and was significantly lower during the COVID-19 period (300.86 per 1,000 patient days) (P < .0001). CONCLUSIONS: The observed reduction of ~70% in the incidence density of HCFA CDI in a context of no reduction in antibiotic use supports the importance of reducing nosocomial transmission by healthcare workers and asymptomatic colonized patients, reinforcing cleaning procedures and reducing patient mobility in the epidemiological control of CDI.

Local prevalence of extended-spectrum beta-lactamase (ESBL) producing Enterobacteriaceae intestinal carriers at admission and co-expression of ESBL and OXA-48 carbapenemase in Klebsiella pneumoniae: a prevalence survey in a Spanish University Hospital.

OBJECTIVE: To assess the prevalence of extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae (ESBL-E) faecal carriers at admission in a University Hospital in Spain. DESIGN: Prevalence survey. SETTING: Pneumology, gastroenterology, urology and neurosurgery units at a university tertiary hospital in Madrid (Spain). PARTICIPANTS: A total of 10 643 patients aged 18 and older admitted from March 2014 to April 2016 with a rectal swab taken at admission or as soon as possible within the first 48 hours. PRIMARY AND SECONDARY OUTCOME MEASURES: Prevalence of ESBL-E faecal carriers and prevalence of ESBL-E infections at admission. RESULTS: The prevalance of ESBL-E carriers at admission was 7.69% (CI 95% 7.18 to 8.19). Most of the isolates were Escherichia coli (77.51%), followed by Klebsiella pneumoniae (20.71%). Eighty-eight (10.41%) of ESBL-E were simultaneous ESBL and carbapenemase (CP) producers, 1.83% in the case of E. coli and 42.86% among K. pneumoniae isolates. Of the ESBL typed, 52.15% belonged to the cefotaximases (CTX-M-15) type and 91.38% of the CP were oxacillinase (OXA-48) type. Only 0.43% patients presented an active infection by ESBL-E at admission. CONCLUSIONS: The prevalence found in our study is very similar to that found in literature. However, we found a high percentage of simultaneous ESBL and CP producers, particularly in K. pneumoniae. Despite the high prevalence of colonised patients, the ESBL-infection rate at admission was very low.

[Patient Safety Culture and teaching: an ins- trument to evaluate knowledge and perceptions among different health professionals of the Madrid Region health system]. / Cultura de Seguridad del Paciente y Docencia: un instrumento para evaluar conocimientos y percepciones en profesionales del sistema sanitario de la Comunidad de Madrid

OBJECTIVE: The patient safety culture (PSC) in health institutions depends on various organizational and human factors. Our aim was to evaluate, as a teaching strategy, the knowledge in patient safety and perceptions about the PSC. METHODS: A convenience sample, with 122 health professionals from Regional Minister of Health's patient safety courses attendees in 2015. Be- fore each course, were delivered a knowledge questionnaire about patient safety (own elaboration) and a validated PSC questionnaire (estimating 3 dimensions: managerial support, perception of safety and expectations / actions). Valuations on CSP were recategorized in positive, negative and neutral, identifying strengths (greater than or equal to 75% of positive evaluations) and opportunities for improvement (greater than or equal to 50% of negative evaluations). At the end of each course an anonymous satisfaction questionnaire was delivered. RESULTS: 60% responded correctly to questions about knowledge in patient safety, identifying areas for improvement in safe practices (hand hygiene and microorganisms resistant to antibiotics, with 66% and 61% of incorrect answers, respectively), and in management of health risks (investigation and identification of adverse events, with 62% and 56% of incorrect answers, respectively). 80% considered the institutional PSC positive, and the perception of safety as an opportunity for improvement (63.9% of negative evaluations). Thus, 88% admitted worrying about patient safety only after adverse incidents, and 65% felt afraid to talk about them. The satisfaction with the teaching methodology was 9.3 points out of 10. CONCLUSIONS: The overall assessment of PSC was mostly positive, identifying specific areas for improvement that allowed orienting the training in patient safety, motivating the participants and suggesting intervention strategies to improve patient safety in our organizations.

OBJETIVO: La cultura de seguridad del paciente (CSP) en las instituciones sanitarias depende de diversos factores organizativos y humanos. Nuestro objetivo fue evaluar, como estrategia docente, los conocimientos y percepciones sobre la CSP. METODOS: Muestra de conveniencia, con 122 profesionales sanitarios y no sanitarios, que asistieron en 2015 a cursos sobre seguridad del paciente organizados por la Consejería de Sanidad de Madrid. Antes de cada curso, autocompletaron un cuestionario de conocimientos sobre seguridad del paciente (elaboración propia) y otro cuestionario validado sobre CSP (estimando 3 dimensiones: apoyo directivo, percepción de seguridad y expectativas/ acciones). Las valoraciones sobre la CSP se recategorizaron en positivas, negativas y neutras, identificando fortalezas (mayor o igual al 75% de valoraciones positivas) y oportunidades de mejora (mayor o igual al 50% de valoraciones negativas). Al finalizar cada curso, cumplimentaron un cuestionario anónimo de satisfacción. RESULTADOS: El 60% respondió correctamente a las preguntas sobre conocimientos en seguridad del paciente, identificando áreas de mejora en prácticas seguras (higiene de manos y microorganismos resistentes a antibióticos, con 66% y 61% de respuestas incorrectas, respectivamente), y en gestión de riesgos sanitarios (investigación e identificación de eventos adversos, con el 62% y 56% de respuestas incorrectas, respectivamente). El 80% consideró positiva la CSP institucional, y la percepción de seguridad como oportunidad de mejora (63,9% de valoraciones negativas). Así, el 88% reconocía preocuparse por la seguridad del paciente sólo tras incidentes adversos, y el 65% sentía miedo a hablar sobre estos. La satisfacción con la metodología docente fue de 9,3 puntos sobre 10. CONCLUSIONES: La valoración global de la CSP fue mayoritariamente positiva, identificándose áreas de mejora específicas utilizadas como estrategia docente para ilustrar conceptos, motivar a los participantes y sugerir estrategias de intervención para mejorar la cultura de seguridad del paciente en nuestras organizaciones.
