Surface cleaning is a well-known control procedure against the dissemination of microorganisms in the hospital environment. This prospective study, carried out in an intensive care unit over the course of 14 days, describes the cleaning/disinfection conditions of four surfaces near patients. In total, 100 assessments of the surfaces were carried out after they were cleaned. Three methods were used to evaluate cleanliness: a visual inspection, an adenosine triphosphate (ATP) bioluminescence assay and testing for the presence of A inspeção visual não se mostrou medida confiável para avaliar a limpeza das superfícies.Os resultados demonstram que a rotina de limpeza adotada precisa ser revista. no se mostró una medida confiable para evaluar la limpieza de las superficies. Los resultados demostraron que la actual rutina de limpieza precisa ser modificada.

This study aimed to understand the profile and severity of patients in physiotherapy treatment after their admission to the intensive care unit (ICU) by applying the APACHE II index. One hundred and forty six subjects, with a mean age of 60.5 ± 19.2 years, were evaluated. The APACHE II index was applied in the first 24 hours to evaluate the severity and mortality risk score. Patients were monitored until hospital discharge or death. The mean APACHE II score was 20±7.3 with an estimated risk of death of 32.4% and observed mortality of 58.2%. The mean hospital stay was 27.8±25.2 days. The patients in physiotherapy at the institution studied were predominantly male, elderly, from the emergency service for treatment (non-surgical), and had clear severity, suggested by the APACHE II score and the observed mortality.Descriptors: APACHE; Mortality; Intensive Care Units. Perfil y gravedad de los pacientes de las unidades de terapia intensiva: aplicación prospectiva del puntaje APACHE IIEste estudio tuvo como objetivo conocer el perfil y la gravedad de pacientes asistidos por la fisioterapia, después de su ingreso en las unidades de terapia intensiva (UTI), a través de la aplicación del puntaje APACHE II. Se evaluaron 146 individuos con promedio de edad de 60,5±19,2 años. El puntaje APACHE II fue aplicado en las primeras 24h para evaluar la gravedad y dar puntuación al riesgo de mortalidad. Los pacientes fueron acompañados hasta el momento del alta hospitalaria o de la muerte. El puntaje APACHE II promedio fue de 20±7,3 con riesgo estimado de muerte de 32,4% y mortalidad observada de 58,2%. El promedio de permanencia hospitalaria fue de 27,8±25,2 días.En los pacientes asistidos por la fisioterapia de la institución investigada, el predominio fue del sexo masculino, ancianos, provenientes de la atención rápida para tratamiento clínico (no quirúrgico) y que presentan nítida gravedad, sugerida por el puntaje APACHE II y por la mortalidad observada.

“…Many studies have reported the presence of MRSA strains in the nasal mucosa, even at low levels, (2,(4)(5)(6)10,20) associated with greater morbidity and mortality. In the present study, the prevalence of MRSA was almost 10%, a value similar to that obtained in other studies involving hospitalized patients or health professionals.…”

“…(2) Staphylococcus sp., mainly S. aureus, is commonly found in the skin and mucosa of humans (especially in the anterior region of the nasal passages), being among the microorganisms most resistant to antibiotics. (3) It is one of the main pathogens that colonizes healthy individuals in the community, leading to infection in patients admitted in hospitals.…”

Objective: To analyze nasal colonization by Staphylococcus sp. its resistance to methicillin, and associated factors in inpatients. Methods: Nasal sample collection, antimicrobial susceptibility tests, and analysis of medical records of inpatients (n=71) were performed, and a questionnaire was applied. Data were analyzed by descriptive and inferential statistics using the chi-square, Student's t, and Mann-Whitney tests (α=5%). Results: Nearly half (44.4%) of the patients who were significantly associated with prolonged antibiotic treatment (p=0.02) was infected with methicillin-resistant Staphylococcus sp.. A significant association was observed between patients with sensitive strains and absence of antibiotic treatment prior to sample collection (p=0.02) or absence of wounds (p=0.003). Conclusion: Strains of methicillin-resistant Staphylococcus sp. were found, and there was no significant difference between the S. aureus species and the coagulase-negative Staphylococci groups, which indicates the degree of spread of methicillin resistance among different species of Staphylococcus. ResumoObjetivo: Analisar a colonização nasal por Staphylococcus sp., sua resistência à meticilina e fatores associados em pacientes internados. Métodos: Foram realizados coleta de amostra nasal, testes de susceptibilidade antimicrobiana e análise de prontuários médicos de pacientes internados (n=71), e foi aplicado um questionário. Os dados foram analisados por meio de estatística descritiva e inferencial usando os testes c 2 , t de Student e Mann-Whitney (α=5%). Resultados: Cerca de metade (44,4%) dos pacientes, significativamente associados ao tratamento antibiótico prolongado (p=0,02) estavam infectados por Staphylococcus sp resistentes à meticilina. Observou-se uma associação significativa entre pacientes com cepas sensíveis e ausência de tratamento com antibiótico antes da coleta (p=0,02) ou ausência de feridas (p=0,003). Conclusão: Foram encontradas cepas de Staphylococcus sp. resistentes à meticilina e não houve diferença significativa entre a espécie S. aureus e os grupos de estafilococos coagulase negativos, o que indica o grau de disseminação da resistência à meticilina entre diferentes espécies de Staphylococcus.
