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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 testing a three-part routine to make needle insertion easier for hemodialysis patients whose veins are hard to access. Before each session, participants receive an ultrasound map of their blood vessels, do handgrip exercises, and apply local cold therapy. The trial compares this approach with usual care to see if it reduces pain and anxiety and improves first-attempt cannulation success. Sixty-nine adults who have needed multiple needle sticks in recent sessions are taking part.

What this could mean

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

Active substance
A combination of pre-cannulation ultrasound vascular mapping, handgrip exercise, and local cryotherapy
What this could lead to
If it works, this could offer a simple, low-risk way to make needle insertion less painful and more reliable for dialysis patients with difficult veins.
What could go wrong
This is a small pilot study, so any benefits may be modest or not hold up in larger trials. The combination approach also requires extra time and equipment, which may not suit every clinic.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Aged 20 years or older. * Receiving maintenance hemodialysis for at least 3 months. * Having an arteriovenous fistula or arteriovenous graft for hemodialysis vascular access. * Having difficult vascular access cannulation, defined as requiring two or more cannulation attempts during at least one of the two most recent hemodialysis sessions. * Able to understand the study information and provide written informed consent. Exclusion Criteria: * Newly created vascular access that had not yet matured or was not clinically stable for routine cannulation. * Acute or clinically unstable medical condition. * Cognitive or language impairment that prevented completion of the study questionnaires. * Contraindication to local cryotherapy or handgrip exercise. * Previous participation in this study or in the study pretest.
