About this study

Official title: Development of a Mortality Prediction Model for Patients Receiving Maintenance Hemodialysis

This prospective, single-center observational cohort study evaluates cardiovascular mortality risk in adults receiving maintenance hemodialysis. During the first year after enrollment, four scheduled assessments are used to characterize demographic factors, dialysis treatment, medication use, routine laboratory measures, and the proportion of serum phosphate measurements within the protocol-defined target range. Participants are subsequently followed for cardiovascular mortality. The study evaluates factors associated with serum phosphate target achievement and develops a cardiovascular mortality prediction model in the overall cohort, with a prespecified subgroup analysis among participants who undergo parathyroidectomy. No treatment or procedure is assigned by the study investigators.

Read the detailed description

This is a prospective observational cohort study conducted at the Hemodialysis Center of Huashan Hospital, Fudan University. Adults aged 18 to 85 years who have received maintenance hemodialysis for at least 3 months and meet the eligibility criteria are enrolled after providing written informed consent.

During the first year after enrollment, four scheduled assessments are performed. Data collected include demographic and clinical characteristics, dialysis treatment parameters, medication use, complete blood count, routine biochemical measurements, immunologic measurements, and other clinically relevant indicators. The principal exposure is the one-year serum phosphate target achievement rate, defined as the number of evaluable serum phosphate measurements within the protocol-defined target range divided by the total number of evaluable scheduled measurements during the one-year assessment period.

Following the one-year exposure-assessment period, participants are followed for cardiovascular mortality for up to 5 years. The primary objective is to evaluate the association between the one-year serum phosphate target achievement rate and cardiovascular mortality and to develop a cardiovascular mortality prediction model. Secondary objectives include identifying factors associated with serum phosphate target achievement and developing a mortality prediction model in the prespecified subgroup of participants who undergo parathyroidectomy as part of routine clinical care.

Descriptive analyses and appropriate parametric or nonparametric tests are used to summarize and compare participant characteristics. Multivariable regression is used to evaluate factors associated with serum phosphate target achievement. Cox proportional hazards regression and prespecified statistical or machine-learning methods are used to evaluate cardiovascular mortality risk and develop prognostic models. All statistical tests are two-sided with an alpha level of 0.05. No study-specific treatment is assigned, and clinical management is determined independently by the treating physicians.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • One-Year Serum Phosphate Target Achievement RateOther

    The one-year serum phosphate target achievement rate is calculated as the number of evaluable scheduled serum phosphate measurements within the protocol-defined target range divided by the total number of evaluable scheduled measurements during the first year after enrollment. Four scheduled assessments are planned. Serum phosphate management is determined by routine clinical care and is not assigned by the study investigators.

  • ParathyroidectomyProcedure or surgery

    Parathyroidectomy received as part of routine clinical care is recorded for prespecified subgroup analysis. The decision to perform parathyroidectomy is made by the treating clinical team and is not assigned by the study investigators.

Study groupRoleWhat they receive
Maintenance Hemodialysis CohortAdults receiving maintenance hemodialysis for at least 3 months at Huashan Hospital are observed without a study-assigned intervention. Demographic, clinical, medication, laboratory, and dialysis-treatment data are recorded during a one-year assessment period, followed by longitudinal ascertainment of cardiovascular mortality. Participants may be classified according to serum phosphate target achievement and parathyroidectomy status for prespecified analyses.

What is being measured

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

  1. Cardiovascular Mortality

    Occurrence and date of death attributed to cardiovascular disease during follow-up, ascertained through study follow-up and available clinical or death records.

    Measured: Up to 5 years after completion of the 1-year exposure-assessment period

Secondary outcomes (2)
  1. One-Year Serum Phosphate Target Achievement Rate

    The number of evaluable scheduled serum phosphate measurements within the protocol-defined target range divided by the total number of evaluable scheduled measurements during the first year after enrollment. Four scheduled assessments are planned for each participant.

    Measured: During the first year after enrollment

  2. Mortality in the Parathyroidectomy Subgroup

    Occurrence and date of death during follow-up among participants who undergo parathyroidectomy as part of routine clinical care. These data are used for prespecified subgroup prognostic modeling.

    Measured: Up to 5 years after completion of the 1-year exposure-assessment period

Questions about this trial

What is this clinical trial studying?

An observational study of End-Stage Kidney Disease (ESKD) and Cardiovascular Disease, run by Huashan 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 3 inclusion and 5 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: finished, as of the sponsor's last update on 17 Aug 2026. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cardiovascular Mortality (time frame: Up to 5 years after completion of the 1-year exposure-assessment period). 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 17 Aug 2026.
