Prevalence and Resistance Patterns of Urinary Tract Infection in Al-Madinah Al-Munawarah, Saudi Arabia: A Retrospective Study.

BACKGROUND: Urinary tract infections (UTIs) are among the most common infections and can cause numerous complications of the renal system. This study aimed to assess the prevalence of uropathogens and their antibiotic susceptibility patterns in Al-Madinah Al-Munawarah, Saudi Arabia. METHODS: Data was collected from patients with UTIs presented at King Fahad General Hospital in Al-Madinah Al-Munawarah, Saudi Arabia. In this retrospective cross-sectional study, UTI microbial-causing agents and antimicrobial resistance profiles identified using automated systems, Phoenix and VITEK2, were collected between July 2022 and June 2023. In addition, minimal demographic data, including date of collection and sex and age of patients were collected and analyzed using Chi-square test. RESULTS: The study included 1394 patients positive for UTI, comprising 50.57% males and 49.43% females (chi-square goodness-of-fit, p > 0.999). Microbial identification and antimicrobial susceptibility tests were performed on UTI-positive cultures. Among UTIs, mono-infection, caused by a single pathogen, was the most prevalent, accounting for 88.16% of cases, whereas poly-infection (caused by multiple pathogens) presented at 11.9%. The most prevalent UTIs' pathogens were E. coli (30.59%), followed by Klebsiella pneumoniae (21.40%), Enterococcus faecalis (8.46%), Pseudomonas aeruginosa (7.81%), Streptococcus agalactiae (6.35%), Enterococcus faecium (3.01%), Proteus mirabilis (3.01%), Enterobacter cloacae (2.52%), Candida sp. (2.44%), Acinetobacter calcoaceticus-baumannii (1.95%), Staphylococcus aureus (1.79%), and Enterobacter aerogenes (1.30%). The most dominant pathogens that coexisted with other uropathogens to cause UTIs were K. pneumoniae and P. mirabilis (9.32%, chi-square 5.550, p = 0.018), K. pneumoniae and P. aeruginosa (8.07%, chi-square 6.285, p = 0.012), K. pneumoniae and E. faecalis (7.45%, chi-square 5.785, p = 0.016), Candida sp. and Enterococcus faecium (4.97%, chi-square 9.176, p = 0.002, and Candida sp. and Acinetobacter calcoaceticus-baumannii (3.11%, chi-square 4.312, p=0.038)). Among the uropathogens, gram-negative pathogens showed resistance to most of the tested antimicrobials (ampicillins, cephalosporins, fluoroquinolones, trimethoprim-sulfamethoxazole, aztreonam, and nitrofurantoin). High rates of resistance were identified to cephalosporins, amoxicillin-clavulanic acid, and trimethoprim-sulfamethoxazole. CONCLUSION: This study reported UT mono-infection and poly-infection in Al-Madinah Al-Munawarah, Saudi Arabia, with a predominant representation from gram-negative bacteria, Enterobacteriaceae. Most of the UT microbial strains showed a highly resistant profile.

Impact of Tracheostomy on COVID-19 ICU Patients in Saudi Arabia: A Retrospective Analysis.

Introduction The COVID-19 pandemic has prompted the development of novel medical interventions, including tracheostomy, a surgical procedure for a direct airway. This study investigates the intricacies of managing critically ill patients in the ICU, focusing on its debated utility in the global crisis. Methods The study assessed the impact of tracheostomy on COVID-19 patients at Al-Ahsa Hospital, Saudi Arabia, using a retrospective cohort design and data from electronic health records and databases. It aimed to provide insights into treatment outcomes and practices. Results The findings of this study shed light on the significant impact of tracheostomy on the course of ICU treatment for COVID-19 patients. Total number of participants were 1389. The study cohort consisted of predominantly non-pregnant individuals with an average body mass index reflective of the regional population. Among the COVID-19 patients, only a small percentage, 63 (4.5%), required tracheostomy, while the majority, 1326 (95.5%), did not undergo this procedure. Analysis of ICU outcomes revealed that a substantial proportion of patients, 223 (16.1%), achieved total cure, while the remaining patients did not. After a 28-day ICU stay, the majority of individuals, 1287 (92.7%), were discharged, while a smaller percentage remained in the ICU, with 77 (5.5%) still requiring mechanical ventilation. Notably, patients who underwent tracheostomy had a significantly longer ICU stay compared to those who did not, with an average of 59 days versus 19 days, respectively. Furthermore, the study found that tracheostomy did not significantly impact ICU discharge outcomes, including death, discharge home, and transfer to another facility. However, it did influence hospital discharge outcomes, with lower mortality rates and a higher rate of transfer to another facility among patients who underwent tracheostomy. These results provide valuable insights into the management and outcomes of critically ill COVID-19 patients in the ICU, particularly in relation to the use of tracheostomy as a treatment intervention. Conclusion The study highlights the dual benefits of tracheostomy in COVID-19 care, extending hospital stays but not increasing ICU discharge rates, emphasizing the need for tailored clinical strategies.
