Risk factors for surgical site infection in cardiac surgery

Abstract

Objective: To analyze the occurrence of surgical site infection (SSI) in patients undergoing cardiac surgery in the period between July 2005, and July 2010. Methods: A quantitative, historical cohort study that evaluated 384 patients in a public teaching hospital. The Statistical Package for the Social Sciences software was used for data analysis and for descriptive analysis, measures of association in contigency tables and logistic regression were used. Results: It was found that 36 (9.4%) patients developed a SSI and that mortality occurred in 14 (38.9%). Staphylococcus aureus was the prevalent microorganism (12, 27.3%) In the multivariate analysis, the risk factors identified as predictors of SSI were male gender, intubation for more than 24 hours, and reintubation. Conclusion: The risk factors predictive of the occurence of SSI (p<0.05) were: male gender, reintubation, and intubation for more than 24 hours. Keywords: Surgical wound infection; Cardiac surgical procedures/adverse effects; Risk factors ResumoObjetivo: Analisar a ocorrência de infecção de sítio cirúrgico (ISC) nos pacientes submetidos à cirurgia cardíaca no período ente julho de 2005 e julho de 2010. Métodos: Estudo de abordagem quantitativa, coorte histórica que avaliou 384 pacientes de um hospital público de ensino. Foi utilizado o software Statistical Package for the Social Sciences para a análise dos dados e para a análise descritiva, foram usadas medidas de associação em tabelas de contingência e regressão logística. Resultados: Verificou-se que 36 (9,4%) pacientes evoluíram com ISC e que a mortalidade foi de 14 (38,9%). O Staphylococcus aureus foi o micro-organismo prevalente 12 (27,3%). Na análise multivariada, os fatores de risco identificados como preditores da ISC foram gênero masculino, tempo de intubação maior que 24 horas e reintubação. Conclusão: Os fatores de risco preditores para ocorrência de ISC (p<0,05) foram: gênero masculino, reintubação e tempo de intubação maior que 24 horas.

(14)(15)(16)(17)(18) For statistical analysis, patients in the study were divided into two groups: ASA I and II (combined), ASA III. This variable showed a statistically significant difference between the group with infection and the group with no infection when tested association with SSI, and this result is corroborated by other researches.…”

“…This result was also shown in other researches that have investigated this association. (15,24,25) The long period of hospitalization increase hospital costs, both to the hospital and patient care, as with the diagnosis and complications. (13,15,25,26) As already pointed out, the occurrence of SSI was 17.2% (n = 16), which shows high percentage, as the expected rate of SSI to the type of surgical procedure studied (clean surgery) is from 1% to 5% according to the parameters established by the CDC.…”

Dressings Indicated in the Treatment of Mediastinitis After Cardiac Surgery: Integrative Review

“…2 There are several factors that contribute to the onset of SSI, which are usually related to the patient, such as malnutrition, obesity, diabetes mellitus, chronic obstructive pulmonary disease (COPD), prolonged corticosteroid therapy, and long intensive care (ICU). 3 In the case of cardiac surgery, the infection that affects organ/space is defined as mediastinitis, being considered a serious complication of the postoperative period, and its prevalence varies in the literature from 0.2% to 5%. 4 Sternal wound infections can be divided into superficial and deep.…”
