Optimizing the Diagnostic Journey in Interstitial Lung Disease: The OPTIMIZE-ILD-1 Trial
OPTIMIZE-ILD-1: A Randomized, Pragmatic, Parallel-Group Trial Evaluating the Impact of an Optimized Diagnostic Circuit on Time to Diagnosis in Patients With Suspected Interstitial Lung Disease
Source: ClinicalTrials.gov · Last updated 21 Oct 2026
Brief summary (registry, in English)
The OPTIMIZE-ILD-1 trial is a prospective, randomized, open-label clinical trial designed to evaluate the impact of a coordinated diagnostic pathway on patients with suspected interstitial lung disease (ILD). In routine clinical practice, diagnostic workflows for ILD are frequently fragmented, involving multiple independent appointments that can lead to significant delays and increased burden for patients and caregivers. This study compares the standard diagnostic pathway against an optimized circuit where core diagnostic procedures-such as high-resolution CT, pulmonary function tests, and laboratory panels-are pre-bundled and scheduled within a coordinated and compressed timeframe. All eligible patients referred for suspected ILD are included consecutively to ensure a pragmatic, real-world representation of the referral population. The primary objective is to measure the time to diagnostic communication, defined as the duration from randomization to the date the patient is formally informed of the final diagnosis following a multidisciplinary team (MDT) consensus. Secondary objectives include assessing the time to MDT diagnosis, the time to treatment initiation (when clinically indicated), socioeconomic cost-burden, and the environmental carbon footprint of the diagnostic journey. Furthermore, the study evaluates health-related quality of life, psychological distress, and clinical frailty, while exploring factors such as language proficiency as determinants of diagnostic equity. Caregiver-related outcomes, including burden and experience measures, are contingent upon the presence of a primary caregiver and the provision of their independent informed consent. The design of this protocol was informed by a patient focus group and is officially endorsed by the 'AIRE' Associació Catalana de Malalts i Trasplantats Pulmonars, ensuring a patient-centered approach that prioritizes the diagnostic journey's efficiency and human impact.

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Prior treatment
- Established diagnosis of ILD previously assigned by another center or specialist.
Other illness
- Clinical instability or acute illness that would prevent reliable completion of diagnostic procedures (e.g., respiratory infection, suspected acute ILD exacerbation, acute heart failure).
- Acute iatrogenic pneumonitis (drug-, chemotherapy- or radiation-induced) with a clear temporal relationship to the offending agent.
- Medical, functional, psychiatric or logistical limitations that, in the investigators' opinion, would interfere with the diagnostic process or data collection.
- Cognitive impairment that prevents informed consent or completion of study questionnaires.
Lab values
- Complete ILD diagnostic work-up already performed (chest CT plus full pulmonary function testing including six-minute walk test plus complete ILD laboratory panel).
Other
- Participation in another interventional clinical trial that may alter the frequency or timing of diagnostic procedures.
- Refusal to participate or to allow the collection or use of clinical data.
Who the study is looking for
- Age 18 years or older.
- Referral for suspected or undiagnosed interstitial lung disease (ILD).
- At least one of the following:
- A finding suggestive of ILD (such as reticulation, ground-glass opacities, traction bronchiectasis or honeycombing) not attributable to another disease, on a CT available at referral that includes the lung parenchyma, regardless of its indication; or
- Persistent or progressive shortness of breath or chronic cough not attributable to another disease, accompanied by at least one of the following: an interstitial or reticular pattern on chest radiograph; reduced forced vital capacity; persistent bibasilar crackles or digital clubbing; a relevant environmental or occupational exposure, autoimmune disease, or suspected drug or radiation toxicity; or a first-degree family history of ILD.
- Ability to provide informed consent.
