About this study

Official title: Pilot Validation Study of Computer Administration of Vision Targeted Quality of Life Instruments

This study will test and compare computerized and paper versions of eye questionnaires. Questionnaires are used in medicine to gain a better understanding of how a disease can impact a person's quality of life. Computerized versions of such questionnaires are often as good as or better than paper versions, but there has been no direct comparison of the two. This study may help in the development of eye questionnaires used to understand symptoms and monitor patients in clinical trials.

People 21 years of age and older with ocular surface disease (OSD) and matched control subjects without OSD may be eligible for this study. All participants undergo the following procedures:

  • Medical and eye history.
  • Vision test and examination of the front part of the eye.
  • Tear measurement: A small piece of paper is placed on the surface of the eye to measure the amount of tears produced. The consistency of the tears is measured by looking at how fast they evaporate from the surface of the eye.
  • Completion of either paper-based or computer-based version of a questionnaire 15 minutes after the eye examination and completion of the other version within 1 week at home. (Subjects who complete the paper version in the clinic are told how to access the computer version online at home or on a library computer; those who complete the computer version in the clinic are given a paper version to take home.)
Read the detailed description

The purpose of this protocol is to compare the health-related quality of life (visual function) reported by participants when using web-based questionnaires versus their responses obtained when using standard paper versions of the questionnaires. This comparison will be performed in a population of patients diagnosed with ocular surface disease (OSD) and in age- and gender-matched controls by using a randomized, cross-over study design. This type of comparative study of patient-reported outcomes has been reported for rheumatology, cardiology, psychiatry, asthma, alcoholism, pain assessment, gastrointestinal disease, diabetes, and allergy populations; however, to our knowledge there have been no reports of such a study from patients with ocular disease. The study will evaluate the agreement between scores reported via two modes of administration: a web-based version and a paper-and-pencil version. Components of three questionnaires commonly used to evaluate visual function, symptoms, and vision-related quality of life in OSD will be included: the initial 5 questions of the Ocular Surface Index (OSDI), question #15 of the National Eye Institute Visual Functioning Questionnaire - 25 (VFQ-25), and specified domains of the National Eye Institute Refractive Error Quality Of Life Instrument-42 (RQL-42) (clarity of vision, near vision, far vision, glare, symptoms, worry, and satisfaction with correction).

The study will also evaluate whether there are differences in mean overall score by age, gender, order of administration, or disease severity.

Ocular surface disease, which includes dry eye disease secondary to a variety of etiologies, is an ophthalmic condition which places a burden not just on functional vision, but also on overall health related quality of life (HRQoL), with an impact similar to that of moderate angina3. This study will add to the body of knowledge in the field of patient-reported outcome measures (PROs), and will be the first to compare the computerized, web-based and paper-based versions of previously validated questionnaires used to assess QoL in subjects with ocular disease.

There has been an increasing interest in assessing PROs in many fields of medicine, especially in the context of clinical trials where HRQoL is an important component of the overall evaluation of an intervention or treatment. As the use of computers increases and accessibility to the internet broadens, there is a tremendous potential in harnessing this technology in the future as a cost-effective, efficient way to gather clinical data on PROs for future ophthalmic clinical trials and studies.

Questions about this trial

What is this clinical trial studying?

An observational study of Eye Disease, run by National Eye Institute (NEI) at 1 site in United States.

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 11 inclusion and 18 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 2 Jul 2017. 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 United States. 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.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00678860, which also lists 3 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 2 Jul 2017.
