Nursing care time in the Intensive Care Unit: evaluation of the parameters proposed in COFEN Resolution Nº 293/04

This study aimed to evaluate the parameters established in COFEN Resolution 293/04 concerning nursing staff dimensioning in adult intensive care units (AICU). The research was conducted in six hospitals in São Paulo City. The daily quantitative average of professionals needed for patient care was calculated according to the parameters established by COFEN. The obtained results were compared with the existing number of daily staff members in these units. It was observed that the proportions recommended by COFEN for the nurse category are superior to those used in the hospitals studied, which represents a challenge for Brazilian nursing. Mean care time values were found appropriate and represent important standards for dimensioning the minimum number of professionals in AICU. This study contributed to the validation of the parameters indicated in Resolution 293/04 for nursing staff dimensioning in the AICU.

Assessment of cardiovascular risk of patients with arterial hypertension of a public health unit

OBJECTIVE: To assess the cardiovascular risk, using the Framingham risk score, in a sample of hypertensive individuals coming from a public primary care unit. METHODS: The caseload comprised hypertensive individuals according to criteria established by the JNC VII, 2003, of 2003, among 1601 patients followed up in 1999, at the Cardiology and Arterial Hypertension Outpatients Clinic of the Teaching Primary Care Unit, at the Faculdade de Medicina de Ribeirão Preto, Universidade de São Paulo. The patients were selected by draw, aged over 20 years, both genders, excluding pregnant women. It was a descriptive, cross-sectional, observational study. The Framingham risk score was used to stratify cardiovascular risk of developing coronary artery disease (death or non-fatal acute myocardial infarction). RESULTS: Age range of 27-79 years ( = 63.2 ± 9.58). Out of 382 individuals studied, 270 (70.7%) were female and 139 (36.4%) were characterized as high cardiovascular risk for presenting diabetes mellitus, atherosclerosis documented by event or procedure. Out of 243 stratified patients, 127 (52.3%) had HDL-C < 50 mg/dL; 210 (86.4%) had systolic blood pressure > 120 mmHg; 46 (18.9%) were smokers; 33 (13.6%) had a high cardiovascular risk. Those added to 139 enrolled directly as high cardiovascular risk, totaled up 172 (45%); 77 (20.2%) of medium cardiovascular risk and 133 (34.8%) of low risk. The highest percentage of high cardiovascular risk individuals was aged over 70 years; those of medium risk were aged over 60 years; and the low risk patients were aged 50 to 69 years. CONCLUSION: The significant number of high and medium cardiovascular risk individuals indicates the need to closely follow them up.

Infecções de corrente sanguínea por bactérias multirresistentes em UTI de tratamento de queimados: experiência de 4 anos

INTRODUÇÃO: O conhecimento do perfil de resistência aos antibióticos das bactérias de um nosocômio é essencial para orientar tratamento adequado dos pacientes. Isso é especialmente importante para os pacientes mais graves, já que o tratamento deve ser instituído antes do resultado das culturas. O objetivo deste estudo foi analisar o perfil das bactérias multirresistentes encontradas nas hemoculturas de pacientes admitidos na Unidade de Tratamento Intensivo (UTI) da Unidade de Queimados do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo. MÉTODO: Foram analisados 178 pacientes internados na UTI para tratamento de queimados, no período de 2009 a 2011, sendo 131 do sexo masculino, com média de idade de 29,2 anos. RESULTADOS: Entre os pacientes analisados, 80 (44,9%) apresentaram hemocultura periférica positiva, sendo 66 (82,5%) casos com bactérias multirresistentes. Em 48 pacientes, foram isoladas Staphylococcus sp., que se apresentaram resistentes à oxacilina em 33 deles. Em 11 pacientes, foram isoladas Acinetobacter baumanii, que se apresentaram resistentes a imipenem em 8 casos. Em 19 pacientes, foram isoladas Pseudomonas sp., resistentes a imipenem em 16 casos. Em 10 pacientes foram isoladas Enterobacter sp., resistentes a amicacina e ciprofloxacina em 2 casos. A presença de bactérias multirresistentes não foi associada a maior ocorrência de óbitos, porém foi verificado maior tempo de internação (52,6 dias vs. 36,3 dias para os grupos com e sem bactérias multirresistentes, respectivamente; P = 0,0306). Não foi encontrada interação significante entre superfície corpórea queimada e presença de bactérias MR. CONCLUSÕES: A presença de bactérias multirresistentes é um problema grave, tanto pela prevalência como pela morbidade e mortalidade associadas.
