Community Health Workers for Prevention of Corneal Ulcers in South India: A Cluster-Randomized Trial.

PURPOSE: To determine whether a community health worker (CHW) program increases referrals to local eye care providers and ultimately reduces the incidence of corneal ulcers. DESIGN: Cluster-randomized trial performed from 2014 to 2017 in rural South India. METHODS: This was a community-based study that included all inhabitants of 42 rural South Indian communities. CHWs were trained to diagnose corneal abrasions and assist participants in seeking care at a local vision center. Given the nature of the intervention, the trial was not masked. The main outcome measure was incident corneal ulcer, defined as an active infiltrate or evidence of a new opacity, as assessed by means of penlight examination during an annual door-to-door census. RESULTS: Twenty-one study clusters were randomized to the CHW intervention and 21 to no intervention. Vision centers diagnosed 195 corneal abrasions from the intervention clusters during the 2-year study (rate, 223 per 100,000 person-years; 95% CI, 28-1743) and 62 from the control clusters (rate, 62 per 100,000 person-years; 95% CI, 8-496; incidence rate ratio, 3.57; 95% CI, 2.01-6.35; P < .001). The estimated incidence of corneal ulceration during the study period was 60 per 100,000 person-years (95% CI, 25-141) in the intervention group and 32 per 100,000 person-years (95% CI, 13-80) in the control group (incidence rate ratio, 1.86; 95% CI, 0.5-6.4; P = .32). CONCLUSIONS: A CHW program resulted in 3.5 times more referrals to local eye care providers for corneal abrasions, but no difference could be detected in the incidence of corneal ulceration. CHW programs provide a mechanism for increasing referrals to eye hospitals. TRIAL REGISTRATION: ClinicalTrials.gov ID: NCT02284698.

Diabetes mellitus in the Tamil Nadu State-Noncommunicable diseases nurse model in diabetic retinopathy screening.

Tamil Nadu is one of the states in India, where the diabetic retinopathy (DR) project was implemented in the Tirunelveli District. Aravind Eye Hospital, Tirunelveli was the mentoring institution and ophthalmology department of Tirunelveli Medical College and Hospital (TVMCH) was the implementing partner. The objective of the project was to develop a district level model for building capacity at the government health system for effective screening, diagnosis and management (primary to tertiary) of diabetic retinopathy. The DR screening, counseling, referral and follow-up tasks were included in the scope of Non- Communicable Disease (NCD) nurses at the respective Community Health Centres and Primary Health Centres using the tele-medicine platform. During the project period (December 2016 to June 2019), 8,574 people with diabetes were registered at the 18 CHCs/PHCs. 6,462 (75.4% of those registered) were screened by NCD staff. The government has agreed to scale up services in 3 more districts.

Quality of life after community-based rehabilitation for blind persons in a rural population of South India.

This study aimed to determine the impact of community-based rehabilitation on the quality of life of blind persons in a rural south Indian population. We performed a population-based survey followed by clinical examinations to identify blind persons in a rural south Indian population. Pre-and-post rehabilitation quality of life of 159 blind persons aged 15 years or above was ascertained through a questionnaire previously validated for use in this population. Post-rehabilitation quality-of-life scales showed some improvement for 151 (95.0%) subjects. The additional benefit from rehabilitation was greatest for the self-care and mobility subscales, ranging from 24.6% to 30.0% for the self care subscale and 37.6% to 44.3% for the mobility subscale with effect sizes of 21.5 and 2.38 respectively. Overall quality of life scores were not significantly different between those who did and did not receive economic rehabilitation (P = 0.1). Blind persons in this rural population benefited considerably from rehabilitation services even if economic rehabilitation is not provided. Initiatives against blindness need to consider rehabilitation of the blind as a priority.

Utilization of community-based rehabilitation services for incurably blind persons in a rural population of southern India.

PURPOSE: To identify barriers in utilisation of community based rehabilitation (CBR) services for incurably blind persons in rural South India. METHODS: A community-based rehabilitation programme for incurably blind persons was initiated in Theni district of southern Tamil Nadu in south India. After door-to-door enumeration and preliminary ocular screening by trained workers at the village, identified blind persons were categorised as either curable or incurable by an ophthalmologist. Trained workers provided rehabilitation, including mobility training (OM), training to perform activities of daily living (ADL), and economic rehabilitation for the incurably blind in their respective villages. RESULTS: Of the 460,984 persons surveyed, 400 (0.09%) were certified as incurably blind including 156 (39.00%) persons blind from birth. Social rehabilitation was provided for 268 (67.00%) incurably blind persons. Economic rehabilitation was provided to 96 persons, and integrated education to 22 children. Nearly one-fifth (n=68, 17.00%) of incurably blind persons refused the services provided. The major reasons for refusal included old age and other illnesses (41.18%), and multiple handicaps (19.12%). Twenty-seven (6.75%) persons had either migrated or died, and 29 (7.25%) persons were already able to function independently. CONCLUSION: Although CBR programmes provide useful services to the incurably blind, a better understanding of barriers is required to improve service utilisation. Developing a standardised data collection format for every CBR programme can result in the creation of a national database of ophthalmic diseases.
