Description
In the retrospective survey of the sensitivity of clinical isolates reported in this journal, patients' backgrounds were also investigated. Some findings are summarized below.<BR>1. Age distribution by sex: Patients with ages 50 years and older accounted for a majority, irrespective of their sexes amounting 67.6% for both sexes combined.<BR>2. Annual distribution of sexes by age group: Females accounted for a majority in younger age brackets, but the proportion of males increased with age, accounting for a majority in patients 70 years or older. This pattern has been repeated practically every year.<BR>3. Distribution of infection types by sex: Complicated urinary tract infections were predominant in males, while simple urinary tract infections were more frequent in females.<BR>4. Annual distribution of sexes by type of infection: Complicated and simple urinary tract infections combined accounted for approximately 70% in both males and females. This pattern has been repeated practically every year.<BR>5. Distribution of infection types by age: Patients of advanced ages were predominant as a whole but this trend was particularly pronounced in complicated urinary tract infection cases.<BR>6. Annual distribution of infection types by age: The frequency of simple urinary tract infections among patients older than 20 years of age declined with age and this pattern has been repeated practically every year. Among patients older than 20 years of age, annual frequencies of complicated urinary tract infections heve been on the decrease.<BR>7. Distribution of isolated bacteria by sex: Escherichia coli was more frequent in females, while Enterococcus faecalis and Pseudomonas aeruginosa were more frequent in males. Compared with the previous year, the frequencies of coagulase-negative staphylococci, Enterococcus spp., and E. coli increased, while that of P. aeruginosa decreased.<BR>8. Distribution of isolated bacteria by age: E. coli was most frequent on the whole, followed by E.faecalis, P. aeruginosa, Klebsiella spp., and coagulase-negative staphylococci, in that order. By age group, E. coli was frequent in younger patients and the frequencies of E. faecalis and P. aeruginosa increased with age.<BR>9. Annual distribution of isolated bacteria by infection type: Coagulase-negative staphylococci increased as a whole and P. aeruginosa and Serratia marcescens decreased compared to 1986, but E.coli continued to be the most frequent. E. coli was isolated from a majority of simple urinary tract infection cases. The frequencies of E. faecalis and P. aeruginosa were high in cases of complicated urinary tract infections.<BR>10. Relationship between duration of treatment with different antibacterial or antibiotic agents and isolated bacteria: The frequency of E. coli had been high before administration but decreased as treatment duration increased; whereas, E. faecalis and P. aeruginosa were found with increased frequencies. Compared to 1986, the frequencies of E. coli and P. aeruginosa declined on the whole, while those of E. faecalis and coagulase-negative staphylococci increased.
