Abstract/Introduction

Purpose

To evaluate knowledge, attitudes, and environment of primary care providers, and to develop a conceptual framework showing their impact on self-reported pre-school vision screening (PVS) behaviors.

Methods

Eligible primary care providers were individuals who filed claims with Medicaid agencies in Alabama, South Carolina, or Illinois, for at least eight well child checks for children aged 3 or 4 years during 1 year. Responses were obtained on-line from providers who enrolled in the intervention arm of a randomized trial to improve PVS. We calculated a summary score per provider per facet: (1) for behavior and knowledge, each correct answer was assigned a value of +1; and (2) for attitudes and environment, responses indicating support for PVS were assigned a value of +1, and other responses were assigned −1.


Conclusion/Results

Results

Responses were available from 53 participants (43 of 49 enrolled pediatricians, 8 of 14 enrolled family physicians, one general physician, and one nurse practitioner). Recognizing that amblyopia often presents without outward signs was positively related to good PVS: [odds ratio (OR) = 3.9; p = 0.06]. Reporting that “preschool VS interrupts patient flow” posed a significant barrier (OR = 0.2; p = 0.05). Providers with high summed scores on attitudes (OR = 6.0; p = 0.03), or knowledge and attitudes (OR = 11.4; p < 0.001) were significantly more likely to report good PVS behavior. There was a significant trend between the number of “good” scores on knowledge, attitudes or environment, and “good” PVS behavior (p = 0.04).

Conclusions

PVS is influenced by positive attitudes, especially when combined with knowledge about amblyopia. Interventions to improve PVS should target multiple facets, emphasizing (1) asymptomatic children are at risk for amblyopia, (2) specific evidence-based tests have high testability and sensitivity for amblyopia in pre-school children, and (3) new tests minimize interruptions to patient flow.


Testimonials


  • I haven't actually used the optometrist side, so my review is limited to the vision therapy offered.  This office was recommended by my occupational therapist for the treatment of my double vision following a stroke.

  • Love this location. I had a brain injury accident from day one one. All the team make you feel you still important and hope in the horizon after when the medical system fell you miserably. Dr. Ikeda very professional and very understanding about your issue. Two tombs up.


    Jim K.

  • My husband and I were immediately impressed with Dr Ikeda. I was hit by a car while cycling which caused broken bones and three brain injuries. The brain injuries caused double vision. Dr. Ikeda examined my eyes and got me started on vision therapy with his occupational therapist who specializes in vision therapy.  She (Chris) is absolutely great.  I am impressed with the array of tools used to help recover my binocular vision.  I am doing things I never thought were possible (balance boards etc).  Chris pushes me and keeps me motivated. I really enjoy my sessions with her.  The office staff is always friendly and they have a wonderful appointment reminder tool that makes it easy to keep my calendar up to date. I am happy the rehab center at Little Co. of Mary recommended them!!


    Teresa S.

  • The Vision Therapy is handled in a separate office through a different door from the shared waiting room. Chris, the vision therapist, has a wide and varied assortment of tools, equipment and resources to best evaluate and treat most vision issues. After just a few visits, my double vision became easier to control, using exercises developed during the therapy process. It was time well-spent.


    Joe M.

  • I have been coming here since I can remember. I love it here. The staff is so amazing and nice. They explain everything they gonna do and never make you feel rushed. Dr. Ikeda has always been my doctor and I would never want another one. He is the doctor for my whole family and is always asking how everyone is doing. I am also so crazy about picking out my frames and have to try so many and each person who helps me take the time and lets me try them all on. I would never want to go anywhere else! I definitely would recommend this office to anyone looking for a great eye doctor.
