AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Appointments scheduled for outpatient medical care across all settings and specialties from January 1, 2016, to December 31, 2023 Exclusion Criteria: * Cancelled appointments, including cancellations made by the patient, medical team, and the appointment management system. * Appointments that do not correspond to scheduled in-person care (Teleconsultations, * Appointments for walk-in demand). * Scheduled appointments that are not for medical care (Health coverage or specialties that do not correspond to scheduled medical care, Appointments for procedures, * Appointments for complementary exams, Appointments for treatments such as speech therapy, physiotherapy, or other therapies). * Spontaneous overflow appointments where the patient spontaneously presents for care at that moment. These appointments cannot be absent as the present and the appointment are assigned simultaneously. * System errors that do not correspond to actual patient medical care appointments (Duplicate cancellations, Appointments where patient and physician coincide).

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

Describe the behavior over time of the nonattendance proportion in scheduled outpatient medical appointments for in-person medical care over an 8-year period (globally and by subgroups: gender, age, medical specialty, and medical coverage).

Timeframe: 2016 to 2023

Evaluate temporal trends and changes (joinpoints) in the absenteeism proportion in scheduled outpatient medical appointments for in-person medical care over the same period.

Timeframe: 2016 to 2023
