Guangdong Uptake of Surgery Trial
Summary
The purpose of this study is:
1. To investigate the effect of patient counseling for cataract patients on (a) subsequent attendance at hospital for examination (b) acceptance of cataract surgery and (c) recommended follow-up after surgery;
2. To examine predictors of hospital attendance, surgery acceptance, and follow-up attendance;
3. To investigate the effect of patient counseling on satisfaction with surgery.
Description
China is home to the 18% of the world's blind people, an estimated 6.6 million. In China, cataract is the leading cause of blindness. In Guangdong, current counseling measures for patients diagnosed with cataract are minimal and often lack adequate descriptions of what cataract is, what causes cataract, and benefits/risks of surgery. A counseling session for cataract patients and family members, conducted by a trained nurse during outreach screening, may increase subsequent attendance at pre-operative examination, acceptance of cataract surgery, and attendance at follow-up examinations. An integral part of this counseling is a short movie consisting of testimony from a former cataract patient who underwent surgery ("pseudophakic motivator"). The use of pseudophakic motivators have been shown to be effective in increasing surgical uptake. In addition, a previously validated "Barriers Questionnaire" will be used to assess predictors of of hospital attendance, surgery acceptance, and follow-up attendance in the categories of cost, transportation, knowledge, and concerns about quality.

Pseudophakia
