RESUMO
Antimicrobial resistance is a major global problem that is primarily driven by the excessive and inappropriate utilization of antibiotics. Urinary tract infections (UTIs) are frequent in primary health care (PHC) and are typically treated with antibiotics. There is ample evidence on the management of this condition in women but not in men. The aim of this study was to describe the epidemiology of UTIs in men in Catalonia, Spain. We conducted a population-based observational cohort study that included male patients diagnosed with UTI within our SIDIAP and CMBD database during the period from 2012 to 2021. UTI diagnoses were grouped into five main groups (cystitis, prostatitis, orchitis and epididymitis, urethritis, and pyelonephritis). Of the 316,762 men with at least one recorded UTI episode, the majority were registered with a diagnosis of cystitis in PHC (212,958 patients). Quinolones were the most commonly recorded treatment for UTIs (between 18.3% and 38.6%, depending on the group), except for urethritis in which a combination of antibiotics (36.7%) was most frequently used. The treatment duration period was between 9 days and 18 days, except for the prostatitis group, in which treatment was extended to 21 days. Urine cultures were documented in up to 30% in the cystitis group. Pyelonephritis was the category linked to most septicemia cases (3.0%). Conclusions: This is the first study to assess UTIs in men using a large PHC database in Spain. The sociodemographic characteristics of our sample are similar to other studies in the literature. In our setting, the use of quinolones for the treatment of UTIs is the most registered, and its duration was between 9 days and 18 days, despite the fact that resistance to quinolones exceeds 20% of the strains in our area.
RESUMO
BACKGROUND: Antibiotic resistance is an individual and public health problem; multidrug-resistant infections could cause an estimated 10 million deaths worldwide by 2050. Unnecessary use of antimicrobials is the most important cause of resistance generation in the community, and an estimated 80% of antimicrobials are prescribed in primary health care, frequently for urinary tract infections (UTIs). OBJECTIVE: This paper presents the protocol for the first phase of the Urinary Tract Infections in Catalonia (Infeccions del tracte urinari a Catalunya) project. We aim to examine the epidemiology of the different types of UTIs in Catalonia (an autonomous community in Spain) and their diagnostic and therapeutic management by health professionals. Furthermore, we aim to evaluate the correlation between types and total consumption of antibiotics for recurrent UTIs in 2 cohorts of women with the presence and severity of infectious complications of urological origin, especially pyelonephritis and sepsis, and 2 potentially serious infections: pneumonia and COVID-19. METHODS: The study is a population-based observational cohort study including adults with a diagnosis of UTI registered in the Information System for the Development of Research in Primary Care (in Catalan: Sistema d'informació per al desenvolupament de la investigació en atenció primària), the Minimum Basic Data Sets of Hospital Discharges and Emergency Departments (in Catalan: Conjunt mínim bàsic de dades a l'hospitalització d'aguts i d'atenció urgent), and data from the Hospital Dispensing Medicines Register (in Catalan: Medicació hospitalària de dispensació ambulatòria) of Catalonia from the period between 2012 and 2021. We will evaluate the variables obtained from the databases to analyze the proportion of different types of UTIs, the percentage of adequate antibiotic treatments prescribed or received for recurrent UTIs according to the national guidelines, and the proportion of UTIs with complications. RESULTS: We expect to describe the epidemiology of UTIs in Catalonia from 2012 to 2021, as well as describe the diagnostic and therapeutic management of UTIs by health professionals. CONCLUSIONS: We expect to find a high percentage of UTI cases with inadequate management according to the national guidelines, considering that on many occasions UTIs are treated with second- or third-line antibiotic therapies with a preference for the longest regimens. Furthermore, the use of antibiotic suppressive therapies, or prophylaxis, in recurrent UTIs will likely be highly variable. Moreover, we aim to determine whether women with recurrent UTIs treated with antibiotic suppressive therapies have a higher incidence and severity of potentially serious future infections, with special attention to acute pyelonephritis, urosepsis, COVID-19, and pneumonia, compared to women who receive antibiotic treatment after they present with a UTI. This is an observational study of data from administrative databases that will not allow causality analysis. The limitations of the study will be handled according to the appropriate statistical methods.
