Codman & Shurtleff Identifier:
First received: October 4, 2005
Last updated: February 5, 2010
Last verified: October 2008
The overall aim of the registry is to develop a longitudinal, observational database that is focused on adult patients with Normal Pressure Hydrocephalus (NPH) that can be used as a source of clinical information for individual surgeons, as well as a national data repository for scientific inquiry and publications.

Condition Phase
Normal Pressure Hydrocephalus Phase 4

Study Type: Observational
Study Design: Time Perspective: Prospective
Official Title: Normal Pressure Hydrocephalus (NPH) Registry

Further study details as provided by Codman & Shurtleff:

Primary Outcome Measures:
  • Database to describe the population of patients with NPH presenting for treatment (assessed at baseline/no safety assessment) [ Time Frame: End of trial ]

Secondary Outcome Measures:
  • To determine frequency of the various treatments for NPH and the outcomes of those treatment (assessed during surgery and at follow-up/no safety assessment) [ Time Frame: End of trial ]

Enrollment: 343
Study Start Date: October 2004
Study Completion Date: September 2008
Primary Completion Date: September 2008 (Final data collection date for primary outcome measure)
Detailed Description:
This is a prospective, multi-center, observational database to collect data on the characteristics, management practices, and patient outcomes of NPH patients. It will be offered to a geographically representative group of U.S. physicians who will enroll NPH patients. The physician makes his/her own clinical decisions; thus, the data captured provides current practice patterns related to diagnosis, management, and results. The registry may also assist physicians in patient follow-up and certain practice management tasks. The data collected will serve to inform the medical community on optimal care for this patient population

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
