Risk factors of carbapenem-resistant Klebsiella pneumoniae infection: a serious threat in ICUs.

BACKGROUND: Nosocomial infections caused by Carbapenem-resistant Klebsiella pneumoniae (CRKP) are increasing. Our aim in this study was to investigate the risk factors of CRKP infections. MATERIAL/METHODS: A retrospective cohort study was performed between 1 January and 31 December 2012 in ICU patients. Data was taken from the hospital infection control database for CRKP. The clinical samples collected from the patients were tested by an automatized system and disk diffusion. SPSS software v11.5 was used for statistical analysis. RESULTS: Totally, 105 Klebsiella pneumoniae isolates were found in 2012 and the carbapenem resistance rate was 48%. The first episode of infection was taken into risk factor analysis. Of the 98 patients, 61 (62.2%) were male and the mean and median ages were 30.4±29.8 and 25 (0-93). The length of stay was longer in the resistant group (p=0.026). Mortality was 48% in the whole group and similar between groups (p=0.533). There was a relationship between meropenem and third-generation cephalosporin use and resistance (OR 3.244 (1.193-8.819) and OR: 3.590 (1.056-12.209). The other risk factors in univariate analysis were: Immunosuppression OR: 2.186 (1.754-2.724), nasogastric catheter OR: 3.562 (1.317-9.634), peripheral arterial catheter OR: 2.545 (1.027-6.307), and being admitted to the neurosurgical unit OR: 4.324 (1.110-16.842). CONCLUSIONS: Restriction of third-generation cephalosporin and carbapenem use and invasive procedures, along with infection control precautions and disinfection policies, may be effective in reducing the carbapenem resistance in ICUs.

Measurement of the knowledge level about breast self-exam among the female employees of a university hospital, Turkey.

OBJECTIVE: Periodic mammography, clinical breast examination and breast self-exam (BSE) facilitate getting a therapeutic response and improve disease prognosis, by leading to early diagnosis of the breast cancer. METHODS: The study included a total of 618 women working in Çukurova University, Faculty of Medicine, as technician, secretary, staff, midwife and doctor. They answered a 22-items questionnaire consisting of questions about general knowledge, 8 of these were about BSE. RESULTS: While it was statistically significant that the education was not correlated with the age of onset of BSE and timing of BSE, the education was significantly efficient in terms of knowing the aim of the BSE, its frequency, post-menopausal BSE time, nipple discharge properties in the case of breast cancer, diagnostic methods and the risks. While it was statistically significant that the profession was not related to age of onset of BSE and knowing the right day of the month on which BSE should be performed, the education was likely to be efficient in knowing the frequency, post-menopausal BSE time, aim of the BSE, nipple discharge properties in the case of breast cancer, diagnostic methods and the risks. When the percentage of giving right answers to the questions and educational background and professional groups were compared, it was seen that the difference of the number of right answers and professional groups was significant. CONCLUSION: Based on our results, we concluded that the education about BSE is warranted in order to increase the likelihood of female healthcare personnel to diagnose breast cancer at an earlier stage, given their role in raising the awareness of the population.
