Costs of eye care services: prospective study from a faith-based hospital in Zambia

The economics of vision impairment and its leading causes: A systematic review

Vision impairment (VI) can have wide ranging economic impact on individuals, households, and health systems. The aim of this systematic review was to describe and summarise the costs associated with VI and its major causes. We searched MEDLINE (16 November 2019), National Health Service Economic Evaluation Database, the Database of Abstracts of Reviews of Effects and the Health Technology Assessment database (12 December 2019) for partial or full economic evaluation studies, published between 1 January 2000 and the search dates, reporting cost data for participants with VI due to an unspecified cause or one of the seven leading causes globally: cataract, uncorrected refractive error, diabetic retinopathy, glaucoma, age-related macular degeneration, corneal opacity, trachoma. The search was repeated on 20 January 2022 to identify studies published since our initial search. Included studies were quality appraised using the British Medical Journal Checklist for economic submissions adapted for cost of illness studies. Results were synthesized in a structured narrative. Of the 138 included studies, 38 reported cost estimates for VI due to an unspecified cause and 100 reported costs for one of the leading causes. These 138 studies provided 155 regional cost estimates. Fourteen studies reported global data; 103/155 (66%) regional estimates were from high-income countries. Costs were most commonly reported using a societal (n = 48) or healthcare system perspective (n = 25). Most studies included only a limited number of cost components. Large variations in methodology and reporting across studies meant cost estimates varied considerably. The average quality assessment score was 78% (range 35-100%); the most common weaknesses were the lack of sensitivity analysis and insufficient disaggregation of costs. There was substantial variation across studies in average treatment costs per patient for most conditions, including refractive error correction (range $12-$201 ppp), cataract surgery (range $54-$3654 ppp), glaucoma (range $351-$1354 ppp) and AMD (range $2209-$7524 ppp). Future cost estimates of the economic burden of VI and its major causes will be improved by the development and adoption of a reference case for eye health. This could then be used in regular studies, particularly in countries with data gaps, including low- and middle-income countries in Asia, Eastern Europe, Oceania, Latin America and sub-Saharan Africa.

Funding paediatric surgery procedures in sub-Saharan Africa

Background

In sub-Saharan Africa, there is a growing awareness of the burden of paediatric surgical diseases. This has highlighted the large discrepancy between the capacity to treat and the ability to afford treatment, and the effect of this problem on access to care. This review focuses on the sources and challenges of funding paediatric surgical procedures in sub-Saharan Africa.

Methods

We undertook a search for studies published between January 2007 and November 2016 that reported the specific funding of paediatric surgical procedures and were conducted in sub-Saharan Africa. Abstract screening, full-text review and data abstraction were completed and resulting data were analysed using Statistical Package for Social Sciences (SPSS) software.

Results

Thirty-five studies met our inclusion criteria and were reviewed. The countries that were predominantly emphasized in the publications reviewed were Nigeria, South Africa, Kenya, Ghana and Uganda. The paediatric surgical procedures involved general paediatric surgery/urology, cardiac surgery, neurosurgery, oncology, plastics, ophthalmology, orthopaedics and otorhinolaryngology. The mean cost of these procedures ranged from 60 to 21,140 United States Dollars (USD). The source of funding for these procedures was mostly out-of-pocket payments (OOPs) by the patient's family in 32 studies, (91.4%) and medical mission/non-governmental organizations (NGOs) in 21 (60%) studies. This pattern did not differ appreciably between the articles published in the initial and latter 5 years of the study period, although there was a trend towards a reduction in OOP funding. Improvements in healthcare funding by individual countries supported by international organizations and charities were the predominant suggested solutions to challenges in funding.

Conclusion

While considering the potential limitations created by diversity in study design, the reviewed publications indicate that funding for paediatric surgical procedures in sub-Saharan Africa is mostly by OOPs made by families of the patients. This may result in limited access to some procedures. Coordinated efforts, and collaboration between individual countries and international agencies, may help to reduce OOP funding and thus improve access to critical procedures.

Direct non-medical costs double the total direct costs to patients undergoing cataract surgery in Zamfara state, Northern Nigeria: a case series

Background

Cost is frequently reported as a barrier to cataract surgery, but few studies have reported costs of accessing surgery in Africa. The purpose of this prospective, facility based study was to compare direct non-medical cost with total direct cost of cataract surgery to patients, and to assess how money was found to cover costs.

Methods

Participants were those aged 17 years and above attending their first post-operative visit after first eye, subsidised, day case cataract surgery. Systematic random sampling was used to select participants who were interviewed to obtain data on socio-demographic details, and on expenditure during the assessment visit, the surgical visit, and the first follow-up visit. Costs were a) direct medical costs (patients’ costs for registration, investigations, surgery, medication), and b) direct non-medical costs (patients’ and escorts’ costs for transport, accommodation, meals). The source of funds to pay for the services received was also assessed.

Results

Almost two thirds (63%) of the 104 participants were men. The mean age of men was 64 (±12.5) years, being 63 (±12.9) years for women. All men were married and 35% of women were widows. 84% of men were household heads compared with 6% of women. The median total direct cost for all visits by all participants was N8,245 (US$51), being higher for men than women (N9,020; US$56 and N7,620; US$47) (p < 0.09) respectively. Direct non-medical cost constituted 49% of total direct cost. 92% of participants had adequate money to pay, but 8% had to sell possessions to raise the money. 20% of unmarried women sold possessions or took out a loan.

Conclusion

Despite the subsidy, cost is still likely to be a barrier to accessing cataract surgery, as the total direct costs represented at least 50 days income for 70% of the local population. Provision of transport would reduce direct non-medical costs.

A cost analysis of pediatric cataract surgery at two child eye health tertiary facilities in Africa

PURPOSE

To determine the direct cost of pediatric cataract surgery at two child eye health tertiary facilities (CEHTFs) in Africa.

METHODS

The direct cost of pediatric cataract surgery was determined by reviewing data collected from two CEHTFs in Zambia and Malawi. Inventory, cost, and usage data of all durable medical equipment, consumable equipment, personnel, and medications were collected and the direct cost per child calculated.

RESULTS

For cataract surgery and related treatment during 2011, the total cost per child was calculated to be $202 for Malawi and $277 for Zambia using figures derived from estimating labor cost allocation proportional to employee time devoted to pediatric cataract management. The one-time equipment cost totaled $178,121 for Malawi and $179,832 for Zambia.

CONCLUSIONS

These cost estimates may serve as a basis for economic decisions aimed at improving access to care, management, and follow-up for children with cataract and provide useful insights for programs dedicated to promoting organizational and financial sustainability for CEHTFs in Africa.
