About this study
The goal of this clinical trial is to evaluate whether an electronic patient-reported outcome measure (ePROM)-guided flexible scheduling system can improve outpatient clinic resource utilisation in patients attending dermatology outpatient clinics for routine follow-up. The main questions it aims to answer are:
- Does the intervention reduce the number of actualised outpatient visits over 12 months compared with standard fixed scheduling?
- Does the intervention group achieve higher adherence to monthly ePROM monitoring, as measured by the proportion of completed ePROM submissions?
- Conditions
- Chronic Dermatological Conditions, Eczema, Urticaria, Psoriasis, Acne
- Being tested
- Flexible ePROM-guided Scheduling System, electronic patient reported outcome measures (ePROMs)

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Flexible ePROM-guided Scheduling SystemBehavioural
Monthly ePROM responses will feed a Bayesian decision system to determine appointment need, which will then be used to make recommendations to patients for scheduling of appointments.
electronic patient reported outcome measures (ePROMs)Behavioural
Monthly electronic patient reported outcome measures (ePROMs) surveys will be sent to patients' mobile devices to capture self-reported disease severity data.
| Study group | Role | What they receive |
|---|---|---|
| Intervention Arm | Experimental | Participants in the intervention arm will not receive routine follow-up appointments at the end of their consultation. Instead, their monthly ePROM responses will feed a two-layer Bayesian decision system to determine appointment need. Receives: Behavioral: Flexible ePROM-guided Scheduling System; Behavioral: electronic patient reported outcome measures (ePROMs) |
| Control Arm | Active comparator | Participants in the control arm will continue standard care, with follow-up appointments scheduled at the end of each consultation. The ePROM responses may be used by patients for self-tracking and will be available to clinicians to inform decision-making at subsequent visits. Receives: Behavioral: electronic patient reported outcome measures (ePROMs) |

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 1 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

How can a doctor refer a patient or contact the research team?
Contact Ellie Choi, MBBS (65 6908 2222, dermatology@nuhs.edu.sg), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of actualised outpatient visits (time frame: baseline to week 52). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Jul 2026.
