BACKGROUND

Diabetic Retinopathy (DR) is an emerging public health issue. DR may lead to severe visual impairment or blindness. Referral communication and tracking system is helpful to monitor patients flow, timeliness and compliance; ensures a close relationship across health facilities and improves patient’s satisfaction. The aim of the study is to improve timely referral flow and compliance of patients diagnosed with DR.

OBJECTIVE

Primary objective: To assess the effect of intervention on timely referral compliance
Secondary objectives: To assess the determinants and cost effectiveness of the intervention for timely referral compliance.

METHODS

This is an operational research study using cluster randomized controlled health facility-based trial. A situational analysis was conducted and problem tree was developed to identify different barriers to referral compliance (long waiting time, lack of knowledge about diabetic retinopathy, its impact on vision and different treatment options).Appropriate solutions were identified through comprehensive literature review and addressing individual barriers to improve poor referral and compliance of patients diagnosed with DR from peripheral centres (referring centre). These solutions were systemically arranged in the form of an intervention package, which will be tested using a cluster-based randomized controlled trial. Ten eligible peripheral hospitals out of 19will be randomly selected and allocated (lottery method); five each in intervention and control groups. Structured counselling and referral communication linkage will be implemented to the intervention group. Structured counselling, health educational material, and telephonic follow-up will be provided by a trained counsellor at the referring centre; patients will be told in detail about DR, its impact on eyes and vision, treatment options available and the treatment cost for different procedures. They will be explained process at LEIRC (referral centre) and a contact person shall facilitate their treatment at the referral centre. Patients in Control group will receive ongoing routine counselling and health education material. We collected data on referral and compliance, and their determinants using referral-and DR-registers, and structured questionnaires for 1.demographic and socioeconomic profile of patients, 2.telephonicfollow-up with noncompliant patients,3.Feedback of those referred, and 4.Performa for clinical information. Compliance is considered when the referred participant reports at referral centre within one month of counselling. Referral compliance between the two groups will be compared using appropriate statistical tests. Adjusted analysis will be conducted.

RESULTS

Due to COVID-19 pandemic the inflow of patients is reduced, thus the duration of the data collection will be increased. In the first 6 months of pilot data collection73 in intervention and 34 in control group were screened for referral; 12(21.82%) and 15(27,2%) already had severe NPDR or PDR at the time of screening.

CONCLUSIONS

Early stage of DR is asymptomatic and can go unnoticed until it affects vision leading to visual impairment and blindness. This study will assess the feasibility and effectiveness of a referral intervention package for improving early diagnosis and treatment with preservation of vision among DR patients.
