What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

Researchers are studying whether daily step counts and other smartwatch measurements can predict which cancer patients will be readmitted to the hospital after discharge. Adults who have just left an oncology ward wear a Huawei smartwatch for 30 days to track steps, heart rate, and sleep through a phone app. They also answer quality-of-life and sleep questionnaires during follow-up visits that last up to 90 days. The goal is to see if lower mobility at home is linked to a higher chance of returning to the hospital.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
smartwatch monitoring of step count, heart rate, and sleep
What this could lead to
If a link emerges, doctors could one day use simple step counts from a smartwatch to flag discharged cancer patients who need extra support before they get readmitted.
What could go wrong
This is an observational study, so it can show a connection but cannot prove that low step counts cause readmission. Results may not hold for patients who differ from those enrolled, and smartwatch data can be incomplete or inaccurate.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study includes oncology patients discharged from the inpatient ward after completing their treatment regimen. Eligible participants are adults (≥18 years) with various cancer types and an Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2, indicating the ability to perform basic ambulatory activities. The cohort will be analyzed for the relationship between post-discharge physical activity-assessed through daily step counts, heart rate, and sleep duration-and the risk of readmission within 90 days. Exclusion criteria include patients with significant mobility limitations, cognitive or psychiatric impairments, or those admitted only for outpatient or same-day treatments.

Inclusion Criteria: * Age: 18 years and older. * Oncology Ward Discharge: Patients who have been discharged from the oncology ward following inpatient treatment. * Cancer Diagnosis: Patients diagnosed with any form of cancer who received treatment in the oncology ward. * Treatment Completion: Patients who have completed their scheduled inpatient oncology treatment and have been discharged. * Performance Status: Patients with an ECOG (Eastern Cooperative Oncology Group) performance status of 0, 1, or 2, indicating they are ambulatory and capable of basic physical activity. * Follow-Up Availability: Patients who are willing and able to participate in a 90-day follow-up period after discharge. * Technology Compliance: Patients who agree to wear a Huawei Watch Fit 2 smartwatch for the first 30 days post-discharge to track daily step count, heart rate, and sleep duration, and have access to a compatible smartphone for remote data monitoring. * Survey Participation: Patients willing to complete the FACT Quality of Life Survey and Pittsburgh Sleep Quality Index before discharge and during follow-up visits. Exclusion Criteria: * Day Treatment Admissions: Patients admitted exclusively for day treatments or outpatient procedures, lacking a full inpatient admission in the oncology ward. * Severe Mobility Limitations: Individuals with substantial mobility impairments, rendering them unable to perform basic ambulatory activities such as walking. * Incompatibility with Technology Requirements: Patients who are unable or unwilling to wear the Huawei Watch Fit 2 smartwatch for data collection purposes or who lack access to a compatible smartphone for remote monitoring. * Non-Adherence to Follow-Up Protocol: Patients who are unwilling or unable to comply with the 90-day follow-up requirements post-discharge. * Incomplete Oncology Treatment Course: Individuals who have not completed the intended course of oncology treatment within the oncology ward prior to discharge. * Cognitive or Psychiatric Impairments: Patients with significant cognitive or psychiatric disorders that impair their ability to provide informed consent or adhere to study protocols.
