An observational study in Chronic Lung Diseases, sponsored by Fondazione IRCCS Ca' Granda, Ospedale Maggiore Policlinico. Recruiting at 68 sites in 33 countries. Per ClinicalTrials.gov, last updated 2026-10-14.
Sponsored by Fondazione IRCCS Ca' Granda, Ospedale Maggiore Policlinico · Observational
This observational, multicentric prospective study aims to understand the prevalence and burden of antimicrobial resistance (AMR) in people with chronic lung diseases (CLD) across the globe, understanding also geographical variability and the risk factors for acquiring AMR.
The primary objective is to understand the prevalence and burden of AMR in CLD both at a local and gloval level.
Secondary objectives include: 1) understanding susceptibilities models of high priority pathogens in people with CLD; 2) understanding geographic variability in the prevalence of AMR in CLD; 3) analysing risk factors for AMR in CLD Participants will be recruited
This is an observational prospective, non-pharmacological, multicentre, international, non-profit study. Data will be collected at all participating centres during two separate two-week periods every year over the course of five consecutive years. Patients with underlying chronic lung diseases in an inpatient or outpatient setting with at least one respiratory sample collected over the prior 12 months will be included. The diagnostic criteria will follow standard clinical procedures. The data will be pseudonymized before being entered into the electronic case report form (eCRF) prepared with RedCap. After signing the informed consent, clinical, demographic, and microbiological variables will be collected. To facilitate the collection of some demographic and clinical variables, a questionnaire will be administered at recruitment.
All procedures whose data will be collected for this protocol fall within normal clinical practice and are in accordance with the standard operating procedures in place at the centre. No procedures, diagnostic tests, or interventions outside the usual clinical practice will be performed for this protocol.
Fondazione IRCCS Ca' Granda, Ospedale Maggiore Policlinico is the lead sponsor of 232 studies on the registry; 83 are open to participants now.
Counted across the registry records on this site, refreshed daily.
The study will include patients of all ages with all kinds of chronic lung disease who underwent testing of at least one respiratory sample in the previous 12 months who attend a respiratory outpatient clinic or are hospitalized during the yearly two two-weeks recruitment windows.
