  Purpose
The purpose of this study is to determine how health literacy impacts glaucoma patient adherence (as measured by following up with the doctor) in Tamil Nadu, India. We hypothesize that individuals with better health literacy will have higher rates of follow-up with their ophthalmologist.

Condition
Patient Noncompliance Health Literacy Glaucoma

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective

Primary Outcome Measures:
  • Association between TOFHLA and REALM and the probability of return for follow-up visit [ Time Frame: 1 year from enrollemnt ]

Secondary Outcome Measures:
  • Association between religion, caste, education, socio-economic status, employment, and available time for doctor visits and the probability of return for follow-up visit. [ Time Frame: 1 year from enrollment ]
  • Association between marital status, number of dependents, family history of glaucoma, travel, need for an escort, understanding of glaucoma, and paying status and the probability of return for follow-up visit. [ Time Frame: 1 year from enrollment ]

Enrollment: 250
Study Start Date: June 2008
Study Completion Date: October 2010
Primary Completion Date: October 2010 (Final data collection date for primary outcome measure)
Groups/Cohorts
1
Adequate Health Literacy (as determined by TOFHLA)
2
Inadequate Health Literacy (as determined by TOFHLA)

Detailed Description:

Many studies have shown the importance of health literacy on patient adherence in the United States (Juzych, M, et al., 2008; Muir, KW, et al., 2006). Low adherence in glaucoma patients leads to increased intraocular pressure, optic nerve damage, and blindness. To date, no research has been done with health literacy and patient adherence in the developing world.

We will use TOFHLA and REALM to assess the health literacy of glaucoma patients in Tamil Nadu, India. We will also survey other demographic information and patient knowledge of glaucoma. This information will be compared with follow-up rates to identify barriers to patient adherence.
