Complex interventions to implement a diabetic retinopathy care pathway in the public health system in Kerala: the Nayanamritham study protocol

Voices of care: unveiling patient journeys in primary care for hypertension and diabetes management in Kerala, India

Background

Diabetes and hypertension are leading public health problems, particularly affecting low- and middle-income countries, with considerable variations in the care continuum between different age, socio-economic, and rural and urban groups. In this qualitative study, examining the factors affecting access to healthcare in Kerala, we aim to explore the healthcare-seeking pathways of people living with diabetes and hypertension.

Methods

We conducted 20 semi-structured interviews and one focus group discussion (FGD) on a purposive sample of people living with diabetes and hypertension. Participants were recruited at four primary care facilities in Malappuram district of Kerala. Interviews were transcribed and analyzed deductively and inductively using thematic analysis underpinned by Levesque et al.'s framework.

Results

The patient journey in managing diabetes and hypertension is complex, involving multiple entry and exit points within the healthcare system. Patients did not perceive Primary Health Centres (PHCs) as their initial points of access to healthcare, despite recognizing their value for specific services. Numerous social, cultural, economic, and health system determinants underpinned access to healthcare. These included limited patient knowledge of their condition, self-medication practices, lack of trust/support, high out-of-pocket expenditure, unavailability of medicines, physical distance to health facilities, and attitude of healthcare providers.

Conclusion

The study underscores the need to improve access to timely diagnosis, treatment, and ongoing care for diabetes and hypertension at the lower level of the healthcare system. Currently, primary healthcare services do not align with the "felt needs" of the community. Practical recommendations to address the social, cultural, economic, and health system determinants include enabling and empowering people with diabetes and hypertension and their families to engage in self-management, improving existing health information systems, ensuring the availability of diagnostics and first-line drug therapy for diabetes and hypertension, and encouraging the use of single-pill combination (SPC) medications to reduce pill burden. Ensuring equitable access to drugs may improve hypertension and diabetes control in most disadvantaged groups. Furthermore, a more comprehensive approach to healthcare policy that recognizes the interconnectedness of non-communicable diseases (NCDs) and their social determinants is essential.

Evaluation of an offline, artificial intelligence system for referable glaucoma screening using a smartphone-based fundus camera: a prospective study

BACKGROUND/OBJECTIVES

An affordable and scalable screening model is critical for undetected glaucoma. The study evaluated the performance of an offline, smartphone-based AI system for the detection of referable glaucoma against two benchmarks: specialist diagnosis following full glaucoma workup and consensus image grading.

SUBJECTS/METHODS

This prospective study (tertiary glaucoma centre, India) included 243 subjects with varying severity of glaucoma and control group without glaucoma. Disc-centred images were captured using a validated smartphone-based fundus camera analysed by the AI system and graded by specialists. Diagnostic ability of the AI in detecting referable Glaucoma (Confirmed glaucoma) and no referable Glaucoma (Suspects and No glaucoma) when compared to a final diagnosis (comprehensive glaucoma workup) and majority grading (image grading) by Glaucoma specialists (pre-defined criteria) were evaluated.

RESULTS

The AI system demonstrated a sensitivity and specificity of 93.7% (95% CI: 87.6-96.9%) and 85.6% (95% CI:78.6-90.6%), respectively, in the detection of referable glaucoma when compared against final diagnosis following full glaucoma workup. True negative rate in definite non-glaucoma cases was 94.7% (95% CI: 87.2-97.9%). Amongst the false negatives were 4 early and 3 moderate glaucoma. When the same set of images provided to the AI was also provided to the specialists for image grading, specialists detected 60% (67/111) of true glaucoma cases versus a detection rate of 94% (104/111) by the AI.

CONCLUSION

The AI tool showed robust performance when compared against a stringent benchmark. It had modest over-referral of normal subjects despite being challenged with fundus images alone. The next step involves a population-level assessment.

Diabetes Health Literacy, Drug Adherence and Factors Associated with Them among Urban Patients in Kerala, India

Aims

The study aimed to assess diabetes health literacy, adherence to diabetes medication, and its associated factors in Kerala, India, the most advanced Indian state in epidemiological transition with the highest literacy level in India.

Materials and methods

We conducted a community-based cross-sectional study among 280 diabetes patients (mean age 62 years, male 42%) selected by multistage cluster sampling. Information on sociodemographic variables was collected using a pretested structured interview schedule. Diabetes health literacy was assessed using the revised Michigan Diabetes Knowledge test. Adherence to diabetes medication was assessed using the Hill-Bone subscale. Binary logistic regression analysis was done to find out the factors associated with diabetes health literacy and medication adherence.

Results

Good diabetes health literacy was reported by 35.7% [95% confidence interval (CI): 30.1-41.6] of the patients. Perfect adherence to diabetes medication was reported by 33.2% of patients (CI: 27.7-39.1). Patients who reported regular newspaper reading [adjusted odds ratio (AOR) 3.16; CI: 1.57-6.30], using the internet (AOR 2.23; CI: 1.11-4.50) and insulin use (AOR 2.60; CI: 1.35-5.00) were more likely to report good diabetes health literacy compared to their counterparts. Patients who reported reading health magazines (AOR 2.75; CI: 1.01-7.60) were more likely to report perfect medication adherence compared to those who did not.

Conclusion

Why diabetes health literacy and medication adherence were low among diabetes patients in the most literate state needs further investigation. Interventions to enhance diabetes health literacy and medication adherence may be undertaken among diabetes patients encouraging them to read newspapers and health magazines regularly and use the internet.

Estimating the costs of blindness and moderate to severe visual impairment among people with diabetes in India

OBJECTIVES

This study provides an estimate of the annual cost of blindness and moderate to severe visual impairment (MSVI) among people with diabetes aged 40 years and above in India in the year 2019.

DESIGN

A cost of illness study.

SETTING

India.

PARTICIPANTS

People with diabetes aged 40 years and above in India in the year 2019.

PRIMARY AND SECONDARY OUTCOME MEASURES

Estimates are provided for the total costs of screening for most common vision-threatening eye conditions, treatment of these conditions, economic activity lost by these people and their family carers whose ability to work is affected, and loss of quality of life experienced by people with diabetes and blindness or MSVI.

RESULTS

It is estimated that for people with diabetes aged 40 years or above, annual screening followed by eye examination where required would cost around 42.3 billion Indian rupees (INR) (4230 crores) per year; treating sight problems around 2.87 billion INR (287 crores) per year if 20% of those needing treatment receive it; and lost economic activity around 472 billion INR (47 200 crores). Moreover, 2.86 million (0.286 crores) quality-adjusted life years (QALYs) are lost annually due to blindness and MSVI. The estimate of lost production is highly sensitive to the proportion of people with MSVI able to work and how their output compares with that of a person with no visual impairment.

CONCLUSIONS

This is the first study to estimate the cost of blindness and MSVI for people aged 40 years and over with diabetes in India. The annual cost to the Indian economy is substantial. This cost will be expected to fall if a successful screening and treatment plan is introduced in India. Further work is suggested using more robust data, when available, to estimate the loss of productivity and loss of QALYs, as this would be worthwhile.

R. L, S. S, Panniyammakal J, Lavis A. Patients', carers' and healthcare providers' views of patient-held health records in Kerala, India: A qualitative exploratory study

INTRODUCTION

Poor medical information transfer across healthcare visits and providers poses a potential threat to patient safety. Patient-held health records (PHRs) may be used to facilitate informational continuity, handover communication and patient self-management. However, there are conflicting opinions on the effectiveness of PHRs, other than in maternal and child care. Moreover, the experiences of users of PHRs in low- and middle-income countries are critical in policy decisions but have rarely been researched.

AIM

This study aimed to explore similarities and differences in the perspectives of patients, carers and healthcare providers (HCPs) on the current PHRs for diabetes and hypertension in Kerala.

METHODS

A qualitative design was used comprising semistructured interviews with patients with diabetes/hypertension (n = 20), carers (n = 15) and HCPs (n = 17) in Kerala, India. Data were analysed using thematic analysis.

RESULTS

Themes generated regarding the experiences with PHRs from each user group were compared and contrasted. The themes that arose were organized under three headings: use of PHRs in everyday practice; the perceived value of PHR and where practice and value conflict. We found that in the use of PHRs in everyday practice, multiple PHRs posed challenges for patients carrying records and for HCPs locating relevant information. Most carers carried all patients' past PHRs, while patients made decisions on which PHR to take along based on the purpose of the healthcare visit. HCPs appreciated having PHRs but documented limited details in them. The perceived value of PHRs by each group for themselves was different. While HCPs placed value on PHRs for enabling better clinical decision-making, preventing errors and patient safety, patients perceived them as transactional tools for diabetes and hypertension medications; carers highlighted their value during emergencies.

CONCLUSION

Our findings suggest that users find a variety of values for PHRs. However, these perceived values are different for each user group, suggesting minimal functioning of PHRs for informational continuity, handover communication and self-management.

PATIENT AND PUBLIC INVOLVEMENT

Patients and carers were involved during the pilot testing of topic guides, consent and study information sheets. Patients and carers gave their feedback on the materials to ensure clarity and appropriateness within the context.

Of primary health care reforms and pandemic responses: understanding perspectives of health system actors in Kerala before and during COVID-19

BACKGROUND

In 2016, the Government of the southern Indian state of Kerala launched the Aardram mission, a set of reforms in the state's health sector with the support of Local Self Governments (LSG). Primary Health Centres (PHCs) were slated for transformation into Family Health Centres (FHCs), with extended hours of operation as well as improved quality and range of services. With the COVID-19 pandemic emerging soon after their introduction, we studied the outcomes of the transformation from PHC to FHC and how they related to primary healthcare service delivery during COVID-19.

METHODS

A qualitative study was conducted using In-depth interviews with 80 health system actors (male n = 32, female n = 48) aged between 30-63 years in eight primary care facilities of four districts in Kerala from July to October 2021. Participants included LSG members, medical and public health staff, as well as community leaders. Questions about the need for primary healthcare reforms, their implementation, challenges, achievements, and the impact of COVID-19 on service delivery were asked. Written informed consent was obtained and interview transcripts - transliterated into English-were thematically analysed by a team of four researchers using ATLAS.ti 9 software.

RESULTS

LSG members and health staff felt that the PHC was an institution that guarantees preventive, promotive, and curative care to the poorest section of society and can help in reducing the high cost of care. Post-transformation to FHCs, improved timings, additional human resources, new services, fully functioning laboratories, and well stocked pharmacies were observed and linked to improved service utilization and reduced cost of care. Challenges of geographical access remained, along with concerns about the lack of attention to public health functions, and sustainability in low-revenue LSGs. COVID-19 pandemic restrictions disrupted promotive services, awareness sessions and outreach activities; newly introduced services were stopped, and outpatient numbers were reduced drastically. Essential health delivery and COVID-19 management increased the workload of health workers and LSG members, as the emphasis was placed on managing the COVID-19 pandemic and delivering essential health services.

CONCLUSION

Most of the health system actors expressed their belief in and commitment to primary health care reforms and noted positive impacts on the clinical side with remaining challenges of access, outreach, and sustainability. COVID-19 reduced service coverage and utilisation, but motivated greater efforts on the part of both health workers and community representatives. Primary health care is a shared priority now, with a need for greater focus on systems strengthening, collaboration, and primary prevention.

Burden of Diabetic Retinopathy amongst People with Diabetes Attending Primary Care in Kerala: Nayanamritham Project

Background: The burden of diabetic retinopathy (DR) in people attending the public health sector in India is unclear. Thirty percent of the population in India is reliant on public healthcare. This study aimed to estimate the prevalence of DR and its risk factors in people with diabetes in the non-communicable disease registers who were attending the family health centres (FHCs) in the Thiruvananthapuram district in Kerala. Methods: This cross-sectional study was conducted over 12 months in 2019 within the framework of a pilot district-wide teleophthalmology DR screening programme. The age- and gender-adjusted prevalence of any DR and sight-threatening DR (STDR) in the whole sample, considering socio-demography, lifestyle and known clinical risk groups, are reported. Results: A total of 4527 out of 5307 (85.3%) screened in the FHCs had gradable retinal images in at least one eye. The age and gender standardised prevalence for any DR was 17.4% (95% CI 15.1, 19.7), and STDR was 3.3% (95% CI 2.1, 4.5). Ages 41–70 years, males, longer diabetes duration, hyperglycaemia and hypertension, insulin users and lower socio-economic status were associated with both DR outcomes. Conclusions: The burden of DR and its risk factors in this study highlights the need to implement DR screening programs within primary care to reduce health inequality.
