Diabetic retinopathy screening barriers among Palestinian primary health care patients: a qualitative study.

PURPOSE: Diabetic Retinopathy (DR) screening among Palestinian diabetic patients is limited. To improve the care of our patients, we explored the barriers to DR screening with a qualitative study. METHODS: Three focus groups were conducted in the northern West Bank. Patients noncompliant with DR screening were recruited from Primary Health Care clinics. Questions were adapted from similar published studies. Informed consent was obtained and group discussions were audio recorded, transcribed, and analyzed for themes by three researchers. RESULTS: Most patients reported financial barriers including the costs of the exam and additional treatments, and transportation to the referral clinic. System related issues were the difficulty of getting appointments and long wait times due to inadequate numbers of ophthalmologists or screening facilities, and physicians failing to recommend screening. Personal concerns related to patients having other priorities, fears about the results, and the negative experiences of family members. Finally, cultural aspects included the stigma of wearing glasses and not doing a test for a condition without symptoms. CONCLUSIONS: Barriers to completing retinopathy screening are multidimensional with financial, personal, educational, health system, and cultural factors. These should be taken into consideration by policy makers in order to increase the uptake and quality of service.

Bilateral Symmetry of Distortions of Tactile Size Perception.

The perceived distance between touches on the limbs is generally bigger for distances oriented across the width of the limb than for distances oriented along the length of the limb. The present study aimed to investigate the coherence of such distortions of tactile size perception across different skin surfaces. We investigated distortions of tactile size perception on the dorsal and palmar surfaces of both the left and right hands as well as the forehead. Participants judged which of two tactile distances felt larger. One distance was aligned with the proximodistal axis (along the body), the other with the mediolateral axis (across the body). Clear distortions were found on all five skin surfaces, with stimuli oriented across the width of the body being perceived as farther apart than those oriented along the length of the body. Consistent with previous results, distortions were smaller on the palmar than on the dorsal hand surface. Distortion on the forehead was intermediate between the dorsal and palmar surfaces. There were clear correlations between distortion on the left and right hands, for both the dorsal and palmar skin surfaces. In contrast, within each hand, there was no significant correlation between the two skin surfaces. Distortion on the forehead was not significantly correlated with that on any of the other skin surfaces. These results provide evidence for bilaterally symmetric representations underlying tactile size perception.
