Compliance to spectacle use in children with refractive errors- a systematic review and meta-analysis.

BACKGROUND

Primary objective of this review was to measure compliance with spectacle use in children with refractive errors. Secondary objective was to understand the reasons for non-compliance.

METHODS

The databases searched were Ovid, EMBASE, CINAHL and Pubmed. All studies up to March, 2018 were included. The search terms were- ((((((Compliance [Title/Abstract]) OR Adherence [Title/Abstract]) OR Compliant [Title/Abstract]) OR Adherent [Title/Abstract])) AND (((Spectacle [Title/Abstract]) OR Spectacles [Title/Abstract]) OR Eye Glasses [Title/Abstract])) AND ((((Child [Title/Abstract]) OR Children [Title/Abstract]) OR Adolescent [Title/Abstract]) OR Adolescents [Title/Abstract]). Two researchers independently searched the databases and initial screening obtained 33 articles. The PRISMA guidelines were followed for conducting and writing the systematic review. Two reviewers assessed data quality independently using the Quality Assessment tool for systematic reviews of observational studies (QATSO). Poor quality studies were those, which had a score of less than 33% on the QATSO tool. Sensitivity analysis was done to determine if poor quality studies effected compliance. Galbraith plot was used to investigate statistical heterogeneity amongst studies. A random effects model was used to pool compliance.

RESULTS

Twenty-three studies were included in the review, of which 20 were included in the quantitative analysis. All the studies were cross sectional. The overall compliance with spectacle use was 40.14% (95% CI- 32.78-47.50). The compliance varied from 9.84% (95% CI = 2.36-17.31) to 78.57% (95% CI = 68.96-88.18). The compliance derived in sensitivity analysis was 40.09%. Reasons for non-compliance were broken/lost spectacles, forgetfulness, and parental disapproval.

CONCLUSION

Appropriate remedial measures such as health education and strengthening vision care services will be required to address poor compliance with spectacle use among children.
