HCRN Core Data Project: Characterizing Patient Populations in the Hydrocephalus Clinical Research Network (HCRN)

May 11, 2026 updated by: richard holubkov, University of Utah
The Hydrocephalus Clinical Research Network (HCRN) has been established by philanthropic funding to conduct multi-institutional research (clinical trials and observational studies) on pediatric hydrocephalus. In addition to philanthropic funding, the HCRN has also received an NIH NINDS Challenge Grant to support the network infrastructure which allows for the conduct of this and other network studies. The HCRN consists of multiple Clinical Centers and the Data Coordinating Center (DCC). The HCRN Core Data Project will obtain data about all neurosurgical hydrocephalus events from the network Clinical Centers, and create a database to be used by HCRN investigators. The ongoing maintenance of the Core Data Project serves two main purposes: 1) it will help investigators understand the variability, progression, and current treatment practices for hydrocephalus in children, with an ultimate goal of better guiding and assessing therapeutic intervention and providing recommendations on patient care and, 2) it will provide pilot and descriptive data necessary for hypothesis generation and study design (i.e. preliminary power analyses, recruitment projections) for studies under development by the HCRN. This multi-institutional database will be maintained throughout the lifetime of the HCRN, and may be useful for tracking trends in pediatric hydrocephalus over time. The Core Data Project will be an invaluable resource to the HCRN and will help stimulate new research protocols, identify potential need for future expansion of the network to incorporate additional patient populations, and provide a descriptive understanding of children with hydrocephalus cared for within the network.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

No older than 18 years (Child, Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Pediatric Hydrocephalus patients.

Description

Inclusion Criteria:

Information for all neurosurgical hydrocephalus patient events will be obtained from each HCRN Clinical Center and will be placed continuously into the Core Data Project. The first calendar year will be 2008, and data collection will continue for the duration of the existence of the HCRN. Neurosurgical hydrocephalus patient events include any operation for the treatment of documented hydrocephalus including the following:

  • Ventriculoperitoneal shunt

Design Details

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
To describe the number and characteristics of neurosurgical hydrocephalus patient events to HCRN Clinical Centers such as patient demographics, etiology of hydrocephalus, diagnostic information, as well as surgical and medical management decisions.
Time Frame: 5+ years
5+ years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
To provide this data to HCRN investigators to support hypothesis generation and study design development for clinical trials and observational studies to be carried out by the HCRN.
Time Frame: 5+ years
5+ years

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
