Adherence to referrals from preschool vision screening and identification of barriers for non-adherence in Israel.

Clinical Relevance: Preschool vision screening is essential for the early detection and treatment of eye and vision problems.

Background: The rate of parental adherence to referrals for comprehensive examination was assessed and factors and potential barriers associated with adherence were identified.

Methods: In a prospective cohort study design, parents were offered to bring their 3-6 year old aged children to free-of-charge vision screening tests at community-based Mother Child Health Centers. Children with abnormal findings were referred to an ophthalmologist examination. Parents were interviewed three to six months after the referral to evaluate adherence and barriers. Barriers were organised into a conceptual framework of parental predisposing and health system factors. Adherence and barriers were assessed by sex, age, ethnic group and socio-economic-status.

Results: Altogether 1283 children (mean age 4.5 ± 0.6 years, 47.8% girls) were screened in the Jerusalem district, Israel. The ethnic groups, Jewish (ultra-Orthodox 51.4%, secular/religious 33.2%) and Arab (15.4%), were similar by age and sex, but not by socio-economic status. The overall referral rate was 23.0% (N = 295). Referral rate was not associated with demographic factors. Overall, 54.3% (N = 160) of parents adhered to the referral to bring the child for a full eye examination. Adherence did not differ with sex, ethnicity or socio-economic-status. Parents of 5-6-year-old children were significantly more likely to adhere than parents of younger children. Of parents who did not adhere, 79.3% were attributed to predisposing factors, 16.3% to system factors and 4.4% to other reasons.

Conclusions: Only half the parents proceeded with the recommended full eye examination. Parents of older children were more likely to adhere to referral. In contrast with vaccinations provided by Mother Child Health Centers, adherence to vision screening did not vary based on ethnicity or socio-economic factors. Since most barriers were associated with predisposing factors of parents, interventions to improve adherence should include parental education.
