Knowledge of glaucoma and associated factors among primary glaucoma patients in Kunming, China.

ABSTRACT

BACKGROUND: To investigate the level of knowledge, attitude, and practices about glaucoma and associated factors among primary glaucoma patients in Kunming, China. METHODS: A hospital-based study was conducted on 93 patients from the First Affiliated Hospital of Kunming Medical University. Interviewer-administered questionnaires were used to collect data after written informed consent. Data were analyzed by SPSS 19.0. Univariate and multivariate logistic regression models were used to identify factors. A Chi-square test was used to analyze the association between knowledge of glaucoma and medication compliance, Mann-Whitney U test was performed to assess the relationship between knowledge of glaucoma and quality of life in patients with glaucoma. P-value < 0.05 was considered statistically significant. RESULTS: Among 93 patients, 55 (59.14%) were aware of glaucoma, 48 (51.61%) had good knowledge of glaucoma, while 45 (48.39%) had poor knowledge. Younger age and duration of glaucoma were associated positively with knowledge of glaucoma. 87 (93.54%) patients got knowledge of their disease from doctors. 79.17% of respondents could use all the anti-glaucoma medications on time, out of which 54.17% had good knowledge of glaucoma while 25.00% had poor knowledge of glaucoma. 30.56% of respondents used to stop anti-glaucoma medications on their own out of which only 9.72% had good knowledge of glaucoma while 20.83% had poor knowledge of glaucoma. Patients with good knowledge of glaucoma had lower scores on the Glaucoma Quality of Life-15 questionnaire. Thus, the compliance to anti-glaucoma medications and glaucoma-related quality of life were better in patients with good knowledge. CONCLUSIONS: The level of knowledge of glaucoma among patients in Kunming is relatively low. Improving knowledge with suitable content for patients through effective multiple means such as the mass media rather than relying only on ophthalmologists may be a veritable first step in combating blindness from glaucoma and enhancing patients' quality of life.
