METHODS: Prospective, surveillance study on PVCR-BSI conducted from September 1, 2013, to May 31, 2019, in 727 intensive care units (ICUs), by members of the International Nosocomial Infection Control Consortium (INICC), from 268 hospitals in 141 cities of 42 countries of Africa, the Americas, Eastern Mediterranean, Europe, South East Asia, and Western Pacific regions. For this research, we applied definition and criteria of the CDC NHSN, methodology of the INICC, and software named INICC Surveillance Online System.
RESULTS: We followed 149,609 ICU patients for 731,135 bed days and 743,508 short-term peripheral venous catheter (PVC) days. We identified 1,789 PVCR-BSIs for an overall rate of 2.41 per 1,000 PVC days. Mortality in patients with PVC but without PVCR-BSI was 6.67%, and mortality was 18% in patients with PVC and PVCR-BSI. The length of stay of patients with PVC but without PVCR-BSI was 4.83 days, and the length of stay was 9.85 days in patients with PVC and PVCR-BSI. Among these infections, the microorganism profile showed 58% gram-negative bacteria: Escherichia coli (16%), Klebsiella spp (11%), Pseudomonas aeruginosa (6%), Enterobacter spp (4%), and others (20%) including Serratia marcescens. Staphylococcus aureus were the predominant gram-positive bacteria (12%).
CONCLUSIONS: PVCR-BSI rates in INICC ICUs were much higher than rates published from industrialized countries. Infection prevention programs must be implemented to reduce the incidence of PVCR-BSIs in resource-limited countries.
Methods: Based on the raw data collected from the Statistical Center of Iran, we studied the population of never-married older adults in the past 25 years and evaluated the growth pattern in different parts of Iran, using ArcGIS software. We also examined the association of singlehood in late life with education in men and women residing in rural and urban areas, using the Chi-square test in SPSS version 22.
Results: A sharp increase was observed in the population of never-married older adults, particularly women, in the past 10 years. Women with formal education from urban and rural areas were more likely to be never married in late life (χ2 = 10455.35, P < 0.001 and χ2 = 271.31, P < 0.001, respectively). Older men with formal education from urban areas were more likely to be never married (χ2 = 35.44, P < 0.001), while men with formal education from rural areas were less likely to be never married (χ2 = 179.13, P < 0.001).
Conclusion: The rate of increase in the population of never-married older women was much higher than the overall growth of older population. Women with formal education, particularly those with university and pre-university degrees, were more likely to be single in late life. It is strongly suggested to determine the causes and process of singlehood in old age in future research, including qualitative studies.
