About this study

Official title: A Multicenter Retrospective Survey of Hyperkalemia Clinical Burden on Hemodialysis Facility-level in China

This study aim to describe hyperkalemia clinical burden and investigate the risk factors associated with the burden on HD facility level.

Read the detailed description

This study is an observational survey study. We estimate 300 hemodialysis (HD) centres will be enrolled in the study. Summarized data on serum potassium (sK) after long interdialytic interval (LIDI), facility practice pattern and patient characteristics which may be related with sK management, and death records information including number of deaths for each centre will be collected. All the data collected and analysed are on HD facility level, not on patient-level. We are aiming to describe hyperkalemia clinical burden and investigate the risk factors associated with the burden on HD facility level. Association between sK management and long-term outcome will also be explored.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To investigate the risk factors associated with hyperkalemia clinical burden on HD facility level

    Examine the association of risk factors at current status to hyperkalemia prevalence on HD facility level

    Measured: 3 years

Secondary outcomes (3)
  1. To describe hyperkalemia clinical burden on HD facility level

    Constitution ratio of different sK levels after LIDI in ranges: (0, 3.5], (3.5, 5.0], (5.0, 5.5], (5.5, 6.0], (6.0, 6.5], (6.5, 7.0], (7.0~) mmol/L in HD centers

    Measured: 3 years

  2. To describe sK management pattern on HD facility level

    Proportion of patients on 3 times/week, 5 times/2 weeks, 2 times/week, less than 2 times/week, and other frequencies of HD treatment Proportion of patients with dialysate potassium concentration at 2.0 mmol/L, 2.5 mmol/L, 3.0 mmol/L and others Proportion of patients with sK testing on monthly, once per 3 months, once per > 3 months and others

    Measured: 3 years

  3. To investigate the risk factors associated with crude mortality on HD facility level

    Examine the association of risk factors back to 3 years ago to crude mortality on HD facility level, risk factors back to 3 years ago including:

    Constitution ratio of different sK levels after LIDI in ranges: (0, 3.5], (3.5, 5.0], (5.0, 5.5], (5.5, 6.0], (6.0, 6.5], (6.5, 7.0], (7.0~) mmol/L in HD centers back to 3 years ago.

    Constitution ratio of last sK levels before death in ranges: (0, 3.5], (3.5, 5.0], (5.0, 5.5], (5.5, 6.0], (6.0, 6.5], (6.5, 7.0], (7.0~) mmol/L in HD centers Key sK management factors (dialysis frequency, dialysate potassium concentration, sK testing frequency) Other factors (length of dialysis/session, patients dialysis vintage, residual renal function, etiology of ESRD, comorbidities, medication use)

    Measured: 3 years

Questions about this trial

What is this clinical trial studying?

An observational study of Hemodialysis Complication, run by Peking University People's Hospital at 1 site in China.

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 8 inclusion and 3 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: status not confirmed, as of the sponsor's last update on 25 Aug 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

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.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Li Zuo (+86(10)88324008, zuoli@bjmu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To investigate the risk factors associated with hyperkalemia clinical burden on HD facility level (time frame: 3 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05020717, which also lists 2 linked publications.

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 25 Aug 2021; AzTrials last refreshed its copy on 8 Nov 2026.
