Epidemiologic changes in bloodstream infections in Andalucía (Spain) during the last decade.

OBJECTIVES: During the last decade, some changes in the epidemiology of invasive infections have been reported; however, specific studies with patient-level data are scarce. The aim of this study was to describe and evaluate the epidemiologic changes in bloodstream infections (BSI) during the last decade in Andalucía, Spain. METHODS: Data from two prospective cohorts of BSI in adults with the same methodology performed 10 years apart in 11 hospitals (eight tertiary and three community) in Andalucía, Spain, were compared; the 2006-7 cohort study was performed between October 2006 and March 2007, and the 2016-17 cohort study was performed between October 2016 and March 2017. Population-based incidence rates were calculated and extrapolated for 1 year. Relative risk ratios were calculated between the 2 periods. Multivariate analyses were performed by logistic regression. RESULTS: Overall, 1262 episodes of BSI were included, 563 (44.6%) in 2006-7 and 699 (55.3%) in 2016-17. Multivariate models selected the following changes in patients' features in 2016-17, after controlling for type of acquisition: higher age (odds ratio (OR) = 1.02; 95% confidence interval [CI] 1.01-1.03), lower urinary catheter (OR = 0.37; 95% CI, 0.26-0.48) and lower Pitt score (OR = 0.76; 95% CI, 0.71-0.82). Adjusted estimations considering patients' features and exposure to procedures showed a reduction in coagulase-negative staphylococci (OR = 0.47; 95% CI, 0.32-0.69), and an increase in Proteus spp. (OR = 3.12; 95% CI, 1.18-8.23) and Candida spp. (OR = 3.01; 95% CI, 1.03-8.86). CONCLUSIONS: We found relevant epidemiologic changes in BSI in our area, including rates, frequency of acquisition types, changes in patient's profiles and aetiologic agents.

Health-related quality of life of patients with HIV: impact of sociodemographic, clinical and psychosocial factors.

OBJECTIVES: This study aims to analyse how a wide group of clinical, social, demographic and psychological factors are related to both physical and mental quality of life in HIV + patients. DESIGN: A cross-sectional study was carried out of 320 HIV + patients in antiretroviral treatment who attended infectious diseases units in four hospitals in the region of Andalusia (Spain). METHODS: Health-Related Quality of Life was measured by the MOS-HIV. Included as independent variables were: sociodemographic variables, variables related to antiretroviral therapy, psychosocial variables like social support (Duke-UNC-11) and psychological morbidity (GHQ-28), variables related to main risk behaviours and clinical variables. RESULTS: In the multiple linear regression analysis, a better PHS quality of life was found to be associated with the absence of mental illness, social support, not being an intravenous drug user and using more than one type of non-injectable drug. A better quality of life, in mental terms, was found to be associated with fewer years as a non-intravenous drug user, having social support, absence of mental illness, not being an intravenous drug user taking only one additional pill, not having any difficulty in taking the medication, and being female. CONCLUSIONS: The study of other non-biological factors that may be related to quality of life has been limited practically to social support and the emotional state. This study highlights the importance of these factors independently from the clinical state, as well as the existence of other psychological and behavioural factors that are also related.
