ABSTRACT
Introducción: La detección y descolonización del Staphylococcus aureus previo a la cirugía, se postula como la opción para disminuir el riesgo de infección en artroplastias. El objetivo de este estudio fue evaluar la efectividad de un programa de cribado de S. aureus en la artroplastia total de rodilla (ATR) y en la artroplastia total de cadera (ATC), la incidencia de infección respecto a una cohorte histórica y su viabilidad económica. Material y métodos: Estudio pre-postintervención en pacientes intervenidos de ATR y ATC en al año 2021. Se realizó protocolo de detección de colonización nasal por S. aureus y erradicación si procedía, con mupirocina intranasal, cultivo postratamiento con el resultado de 3 semanas entre cultivo postratamiento y cirugía. Se evalúan medidas de eficacia, se analizan costes y se comprara la incidencia de infección respecto a una serie histórica de pacientes intervenidos entre enero y diciembre de 2019, realizando análisis estadístico descriptivo y comparativo. Resultados: Los grupos fueron comparables estadísticamente. Se realizó el cultivo en el 89%, siendo 19 (13%) pacientes positivos. Se confirmó el tratamiento en 18, cultivo control en 14, todos descolonizados; ninguno sufrió infección. Un paciente con cultivo negativo sufrió infección por S. epidermidis. En cohorte histórica: 3 sufrieron infección profunda por S. epidermidis, E. cloacae y S. aureus. El coste del programa fue de 1.661,85. Conclusión: El programa de cribado detectó el 89% de los pacientes. La prevalencia de infección en el grupo intervención era menor que en la cohorte, siendo S.epidermidis el microorganismo causante, diferente a S. aureus descrito en la literatura y en la cohorte. Consideramos que este programa es económicamente viable, siendo sus costes reducidos y asumibles.(AU)
Introduction: Detection and decolonization of Staphylococcus aureus prior to surgery is postulated as an option to reduce the risk of infection in arthroplasties. The aim of this study was to evaluate the effectiveness of a screening program for S. aureus in total knee arthroplasty (TKA) and total hip arthroplasty (THA), the incidence of infection with respect to a historical cohort, and its economic viability. Material and methods: Pre-post intervention study in patients undergoing primary knee and hip prostheses in 2021, a protocol was carried out to detect nasal colonization by S. aureus and eradication if appropriate, with intranasal mupirocin, post-treatment culture with results three weeks between post-treatment culture and surgery. Efficacy measures are evaluated, costs are analyzed and the incidence of infection is compared with respect to a historical series of patients operated on between January and December 2019, performing a descriptive and comparative statistical analysis. Results: The groups were statistically comparable. Culture was performed in 89%, with 19 (13%) positive patients. Treatment was confirmed in 18, control culture in 14, all decolonized; none suffered infection. One culture-negative patient suffered from Staphylococcus epidermidis infection. In historical cohort: 3 suffered deep infection by S. epidermidis, Enterobacter cloacae, S. aureus. The cost of the program is 1661.85. Conclusion: The screening program detected 89% of the patients. The prevalence of infection in the intervention group was lower than in the cohort, with S. epidermidis being the main microorganism, different from S. aureus described in the literature and in the cohort. We believe that this program is economically viable, as its costs are low and affordable.(AU)
