Situational analysis of diabetic retinopathy treatment Services in Ghana.

BACKGROUND: Although the equitable distribution of diabetic retinopathy (DR) services across Ghana remains paramount, there is currently a poor understanding of nationwide DR treatment services. This study aims to conduct a situation analysis of DR treatment services in Ghana and provide evidence on the breadth, coverage, workload, and gaps in service delivery for DR treatment. METHODS: A cross-sectional study was designed to identify health facilities which treat DR in Ghana from June 2018 to August 2018. Data were obtained from the facilities using a semi-structured questionnaire which included questions identifying human resources involved in DR treatment, location of health facilities with laser, vitreoretinal surgery and Anti-vascular endothelial growth factor therapy (Anti-VEGF) for DR treatment, service utilisation and workload at these facilities, and the average price of DR treatment in these facilities. RESULTS: Fourteen facilities offer DR treatment in Ghana; four in the public sector, seven in the private sector and three in the Christian Health Association of Ghana (CHAG) centres. There was a huge disparity in the distribution of facilities offering DR services, the eye care cadre, workload, and DR treatment service (retinal laser, Anti-VEGF, and vitreoretinal surgery). The retinal laser treatment price was independent of all variables (facility type, settings, regions, and National Health Insurance Scheme coverage). However, settings (p = 0.028) and geographical regions (p = 0.010) were significantly associated with anti-VEGF treatment price per eye. CONCLUSION: Our results suggest a disproportionate distribution of DR services in Ghana. Hence, there should be a strategic development and implementation of an eye care plan to ensure the widespread provision of DR services to the disadvantaged population as we aim towards a disadvantaged population as we aim towards a universal health coverage.

Effectiveness of peer support to increase uptake of retinal examination for diabetic retinopathy: study protocol for the DURE pragmatic cluster randomized clinical trial in Kirinyaga, Kenya.

BACKGROUND: All patients with diabetes are at risk of developing diabetic retinopathy (DR), a progressive and potentially blinding condition. Early treatment of DR prevents visual impairment and blindness. The natural history of DR is that it is asymptomatic until the advanced stages, thus annual retinal examination is recommended for early detection. Previous studies show that the uptake of regular retinal examination among people living with diabetes (PLWD) is low. In the Uptake of Retinal Examination in Diabetes (DURE) study, we will investigate the effectiveness of a complex intervention delivered within diabetes support groups to increase uptake of retinal examination. METHODS: The DURE study will be a two-arm pragmatic cluster randomized clinical trial in Kirinyaga County, Kenya. Diabetes support groups will be randomly assigned to either the intervention or usual care conditions in a 1:1 ratio. The participants will be 700 PLWD who are members of support groups in Kirinyaga. To reduce contamination, the unit of randomization will be the support group. Peer supporters in the intervention arm will receive training to deliver the intervention. The intervention will include monthly group education on DR and individual member reminders to take the eye examination. The effectiveness of this intervention plus usual care will be compared to usual care practices alone. Participant data will be collected at baseline. The primary outcome is the proportion of PLWD who take up the eye examination at six months. Secondary outcomes include the characteristics of participants and peer supporters associated with uptake of eye examination for DR. Intention-to-treat analysis will be used to evaluate the primary and secondary outcomes. DISCUSSION: Eye care programs need evidence of the effectiveness of peer supporter-led health education to improve attendance to retinal screening for the early detection of DR in an African setting. Given that the intervention combines standardization and flexibility, it has the potential to be adopted in other settings and to inform policies to promote DR screening.

A tool for planning retinoblastoma services in sub-Saharan Africa.

BACKGROUND: Cancer care remains inadequate in low-middle income countries (LMICs). Children with cancer have 80% chance of surviving in high-income countries compared to 20% in LMICs. Retinoblastoma (RB), an aggressive eye cancer of childhood and top childhood cancer in sub-Saharan Africa (SSA), has a low survival rate, due to a delay in diagnosis and abandonment of treatment. The purpose of this study is to provide a tool for planning human resources required to manage RB in SSA. PROCEDURE: Online tool was developed with 19 modifiable fields and 23 estimates. Routine data were used to populate modifiable fields: population, birthrate, infant mortality rate, and total fertility rate. Values were held constant: frequency, 1:17,000; familial cases, 8%; unilateral RB, 74%; extraocular disease, 70%; and survival postextraocular treatment, 10%. RESULTS: One thousand twenty-three RB incident and familial cases are estimated each year across Ethiopia, Ghana, Malawi, Nigeria, Tanzania, Uganda, Zambia, and Zimbabwe: 75 familial, 700 unilateral, 717 extraocular disease, and 645 palliative. Nigeria represents 431 cases and Zimbabwe 33 cases. Over the eight countries, a total of 41,558 patient visits are estimated each year consisting of unilateral enucleation, follow-up visits, intensive treatment, and familial screening, with a total of 2,802 prosthetic eyes being required each year. CONCLUSIONS: In the absence of data, estimates are essential for planning countrywide medical services. More attention is needed around planning for services from the Ministry level including emphasis on building multidisciplinary teams for diseases such as RB, including countrywide database and integrated clinical practice guidelines among all levels of care.

Analysis of an international collaboration for capacity building of human resources for eye care: case study of the college-college VISION 2020 LINK.

BACKGROUND: There is an extreme health workforce shortage in Eastern, Central, and Southern Africa. Shortage of eye care workers impedes effective implementation of prevention of blindness programs. The World Health Organization has identified education, partnership, leadership, financing, and policy as intertwined interventions that are critical to resolving this crisis on the long term. CASE PRESENTATION: The VISION 2020 LINK between the College of Ophthalmology of Eastern, Central, and Southern Africa and the Royal College of Ophthalmologists in the United Kingdom aims to increase the quantity and quality of eye care training in East, Central, and Southern Africa through a focus on five strategic areas: fellowship examination for ophthalmologists, training the trainers, curriculum development for residents in ophthalmology and ophthalmic clinical officers, continuous professional development (CPD), and mentoring program for young ophthalmologists. This study examined how education and partnership can be linked to improve eye care, through an evaluation of this north-south link based on its own targets and established frameworks to guide north-south links. METHODS: An exploratory qualitative case study design was used. Twenty-nine link representatives were recruited through purposive sampling and snowballing. Face-to-face interviews were conducted using a semi-structured interview schedule that incorporated the components of a successful link from an existing framework. Documents pertaining to the link were also examined. Thematic analysis was used for data analysis. RESULTS: The findings revealed that the perception to the contribution of the link to eye care in the region is generally positive. Process indicators showed that the targets in three strategic objectives of the link have been achieved. Framework-based evaluation also showed that the link is successful. Mutual learning and development of friendships were the most commonly identified success factors. Inadequate awareness of the link by college members is a key challenge. CONCLUSION: The study concludes that the link is active and evolving and has achieved most of its targets. Further developments should be directed to influence health system strengthening in Eastern, Central, and Southern Africa more strategically. The study recommends expansion of the scope of collaboration to involve multiple health system building blocks.

Visual health screening by schoolteachers in remote communities of Peru: implementation research.

OBJECTIVE: To describe the adaptation and scaling-up of an intervention to improve the visual health of children in the Apurimac region, Peru. METHODS: In a pilot screening programme in 2009-2010, 26 schoolteachers were trained to detect and refer visual acuity problems in schoolchildren in one district in Apurimac. To scale-up the intervention, lessons learnt from the pilot were used to design strategies for: (i) strengthening multisector partnerships; (ii) promoting the engagement and participation of teachers and (iii) increasing children's attendance at referral eye clinics. Implementation began in February 2015 in two out of eight provinces of Apurimac, including hard-to-reach communities. We made an observational study of the processes and outcomes of adapting and scaling-up the intervention. Qualitative and quantitative analyses were made of data collected from March 2015 to January 2016 from programme documents, routine reports and structured evaluation questionnaires completed by teachers. FINDINGS: Partnerships were expanded after sharing the results of the pilot phase. Training was completed by 355 teachers and directors in both provinces, belonging to 315 schools distributed in 24 districts. Teachers' appraisal of the training achieved high positive scores. Outreach eye clinics and subsidies for glasses were provided for poorer families. Data from six districts showed that attendance at the eye clinic increased from 66% (45/68 children referred) in the pilot phase to 92% (237/259) in the implementation phase. CONCLUSION: Adaptation to the local context allowed the scaling-up of an intervention to improve visual health in children and enhanced the equity of the programme.

What is the coverage of retina screening services for people with diabetes? Protocol for a systematic review and meta-analysis.

INTRODUCTION: Diabetic retinopathy is a leading cause of vision impairment globally. Vision loss from diabetic retinopathy can generally be prevented by early detection and timely treatment. The WHO included a measure of service access for diabetic retinopathy as a core indicator in the Eye Care Indicator Menu launched in 2022: retina screening coverage for people with diabetes. The aim of this review is to provide a comprehensive global and regional summary of the available information on retina screening coverage for people with diabetes. METHODS AND ANALYSIS: A search will be conducted in five databases without language restrictions for studies from any country reporting retina screening coverage for adults with any type of diabetes at the national or subnational level using data collected since 1 January 2000 until the search date. We will also seek reports and coverage statistics from government websites of all WHO member states. Two investigators will independently screen studies, extract relevant data and assess risk of bias of included studies. The results of the review will be reported using the Preferred Reporting Items for Systematic Review and Meta-Analysis guideline. We will summarise the range of coverage definitions reported across included studies and present the median retina screening coverage in WHO regions and by World Bank country income level. Depending on the availability of data, we will conduct meta-analysis to assess disparities in retina screening coverage for people with diabetes by factors in the PROGRESS framework (Place of residence, Race/ethnicity/culture/language, Occupation, Gender/sex, Religion, Education, Socioeconomic status and Social capital). ETHICS AND DISSEMINATION: This review will only include published data thus no ethical approval will be sought. The findings of this review will be published in a peer-reviewed journal and presented at relevant conferences. PROTOCOL REGISTRATION NUMBER: OSF registration 17/10/2023: https://osf.io/k5p69.

Prevalence of hypertension, diabetes, obesity, multimorbidity, and related risk factors among adult Gambians: a cross-sectional nationwide study.

BACKGROUND: As countries progress through economic and demographic transition, chronic non-communicable diseases (NCDs) overtake a previous burden of infectious diseases. We investigated the prevalence of hypertension, diabetes, obesity, and multimorbidity in older adults in The Gambia. METHODS: We embedded a survey on NCDs into the nationally representative 2019 Gambia National Eye Health Survey of adults aged 35 years or older. We measured anthropometrics, capillary blood glucose, and blood pressure together with sociodemographic information, personal and family health history, and information on smoking and alcohol consumption. Hypertension was defined as systolic blood pressure of 140 mmHg or more, diastolic blood pressure of 90 mmHg or more, or receiving treatment for hypertension. Diabetes was defined as fasting capillary blood glucose of 7 mmol/L or more, random blood glucose of 11·1mmol/L or more, or previous diagnosis or treatment for diabetes. Overweight was defined as BMI of 25-29·9 kg/m2 and obesity as 30 kg/m2 or more. Multimorbidity was defined as the coexistence of two or more conditions. We calculated weighted crude and adjusted estimates for each outcome by sex, residence, and selected sociodemographic factors. FINDINGS: We analysed data from 9188 participants (5039 [54·8%] from urban areas, 6478 [70·5%] women). The prevalence of hypertension was 47·0%; 2259 (49·3%) women, 2052 (44·7%) men. The prevalence increased with age, increasing from 30% in those aged 35-45 years to over 75% in those aged 75 years and older. Overweight and obesity increased the odds of hypertension, and underweight reduced the odds. The prevalence of diabetes was 6·3% (322 [7·0%] women, 255 [5·6%] men), increasing from 3·8% in those aged 35-44 years to 9·1% in those aged 65-75 years, and then declining. Diabetes was much more common among urban residents, especially in women (peaking at 13% by age 65 years). Diabetes was strongly associated with BMI and wealth index. The prevalence of obesity was 12·0% and was notably higher in women than men (880 [20·2%] vs 170 [3·9%]). Multimorbidity was present in 932 (10·7%), and was more common in women than men (694 [15·9] vs 238 [5·5]). The prevalence of smoking was 9·7%; 5 (0·1%) women, 889 (19·3%) men. Alcohol consumption in the past year was negligible. INTERPRETATION: We have documented high levels of NCDs and associated risk factors in Gambian adults. This presents a major stress on the country's fragile health system that requires an urgent, concerted, and targeted mutisectoral strategy.

Sight impairment registration in Trinidad: trend in causes and population coverage in comparison to the National Eye Survey of Trinidad and Tobago.

BACKGROUND: Little was known about the population coverage and causes of sight impairment (SI) registration within the Caribbean, or the extent to which register studies offer insights into population eye health. METHODS: We compared causes of SI registration in the Trinidad and Tobago Blind Welfare Association (TTBWA) register with findings from the 2014 National Eye Survey of Trinidad and Tobago (NESTT), and estimated registration coverage. Cross-sectional validation studies of registered clients included interviews, visual function and cause ascertainment in July 2013, and interviews and visual function in July 2016. RESULTS: The TTBWA register included 863 people (all ages, 48.1%(n = 415) male) registered between 1951 and 2015. The NESTT identified 1.1%(75/7158) people aged ≥5years eligible for partial or severe SI registration, of whom 49.3%(n = 37) were male. Registration coverage was approximately 7% of the eligible population of Trinidad. Nevertheless, there was close agreement in the causes of SI comparing the register and population-representative survey. Glaucoma was the leading cause in both the register (26.1%,n = 225) and population-based survey (26.1%, 18/69 adults), followed by cataract and diabetic retinopathy. In the validation studies combined, 62.6%(93/151) clients had severe SI, 28.5%(43/151) had partial SI and 9.9%(15/151) did not meet SI eligibility criteria. SI was potentially avoidable in at least 58%(n = 36/62) adults and 50%(n = 7/14) children. CONCLUSION: We report very low register coverage of the SI population, but close agreement in causes of SI to a contemporaneous national population-based eye survey, half of which resulted from preventable or treatable eye disease.

Artificial intelligence-supported diabetic retinopathy screening in Tanzania: rationale and design of a randomised controlled trial.

INTRODUCTION: Globally, diabetic retinopathy (DR) is a major cause of blindness. Sub-Saharan Africa is projected to see the largest proportionate increase in the number of people living with diabetes over the next two decades. Screening for DR is recommended to prevent sight loss; however, in many low and middle-income countries, because of a lack of specialist eye care staff, current screening services for DR are not optimal. The use of artificial intelligence (AI) for DR screening, which automates the grading of retinal photographs and provides a point-of-screening result, offers an innovative potential solution to improve DR screening in Tanzania. METHODS AND ANALYSIS: We will test the hypothesis that AI-supported DR screening increases the proportion of persons with true referable DR who attend the central ophthalmology clinic following referral after screening in a single-masked, parallel group, individually randomised controlled trial. Participants (2364) will be randomised (1:1 ratio) to either AI-supported or the standard of care DR screening pathway. Participants allocated to the AI-supported screening pathway will receive their result followed by point-of-screening counselling immediately after retinal image capture. Participants in the standard of care arm will receive their result and counselling by phone once the retinal images have been graded in the usual way (typically after 2-4 weeks). The primary outcome is the proportion of persons with true referable DR attending the central ophthalmology clinic within 8 weeks of screening. Secondary outcomes, by trial arm, include the proportion of persons attending the central ophthalmology clinic out of all those referred, sensitivity and specificity, number of false positive referrals, acceptability and fidelity of AI-supported screening. ETHICS AND DISSEMINATION: The London School of Hygiene & Tropical Medicine, Kilimanjaro Christian Medical Centre and Tanzanian National Institute of Medical Research ethics committees have approved the trial. The results will be submitted to peer-reviewed journals for publication. TRIAL REGISTRATION NUMBER: ISRCTN18317152.

Differences in Childhood Growth Parameters Between Patients With Somatic and Heritable Retinoblastoma.

Purpose: Little is known regarding differences in childhood growth between somatic and heritable retinoblastoma (Rb) populations. We aimed to compare childhood growth parameters between somatic and heritable Rb cohorts at birth and at time of diagnosis with Rb. Methods: A multinational, longitudinal cohort study was conducted with patients from 11 centers in 10 countries who presented with treatment naïve Rb from January to December 2019. Variables of interest included age, sex, and size characteristics at birth and at time of presentation, as well as germline mutation status. After Bonferroni correction, results were statistically significant if the P value was less than 0.005. Results: We enrolled 696 patients, with 253 analyzed after exclusion criteria applied. Between somatic (n = 39) and heritable (n = 214) Rb cohorts, with males and females analyzed separately, there was no significant difference in birth weight percentile, weight percentile at time of diagnosis, length percentile at time of diagnosis, weight-for-length percentile at time of diagnosis, or change of weight percentile from birth to time of diagnosis. Patients with heritable Rb had a smaller mean weight percentile at birth and smaller mean weight and length percentiles at time of diagnosis with Rb, although this difference was not statistically significant. All cohorts experienced a slight negative change of weight percentile from birth to time of diagnosis. No cohort mean percentiles met criteria for failure to thrive, defined as less than the 5th percentile. Conclusions: Children with Rb seem to have normal birth and childhood growth patterns. There is no definitive evidence that somatic or heritable Rb has a biological or environmental impact on childhood growth parameters.

Eye Health Integration in Southern and Eastern Africa: A Scoping Review.

Integrated health systems are deemed necessary for the attainment of universal health coverage, and the East, Central, and Southern Africa Health Community (ECSA-HC) recently passed a resolution to endorse the integration of eye health into the wider health system. This review presents the current state of integration of eye health systems in the region. Eight hundred and twelve articles between 1946 and 2020 were identified from four electronic databases that were searched. Article selection and data charting were done by two reviewers independently. Thirty articles met the eligibility criteria and were included in the narrative synthesis. Majority were observational studies (60%) and from Tanzania (43%). No explicit definition of integration was found. Eye health was prioritized at national level in some countries but failed to cascade to the lower levels. Eye health system integration was commonly viewed in terms of service delivery and was targeted at the primary level. Eye care data documentation was inadequate. Workforce integration efforts were focused on training general health-care cadres and communities to create a multidisciplinary team but with some concerns on quality of services. Government funding for eye care was limited. The findings show eye health system integration in the ECSA-HC region has been in progress for about four decades and is focused on the inclusion of eye health services into other health-care programs. Integration of comprehensive eye care into all the health system building blocks, particularly financial integration, needs to be given greater emphasis in the ECSA-HC.

Artificial intelligence for diabetic retinopathy in low-income and middle-income countries: a scoping review.

Diabetic retinopathy (DR) is a leading cause of blindness globally. There is growing evidence to support the use of artificial intelligence (AI) in diabetic eye care, particularly for screening populations at risk of sight loss from DR in low-income and middle-income countries (LMICs) where resources are most stretched. However, implementation into clinical practice remains limited. We conducted a scoping review to identify what AI tools have been used for DR in LMICs and to report their performance and relevant characteristics. 81 articles were included. The reported sensitivities and specificities were generally high providing evidence to support use in clinical practice. However, the majority of studies focused on sensitivity and specificity only and there was limited information on cost, regulatory approvals and whether the use of AI improved health outcomes. Further research that goes beyond reporting sensitivities and specificities is needed prior to wider implementation.

Real-world evaluation of smartphone-based artificial intelligence to screen for diabetic retinopathy in Dominica: a clinical validation study.

OBJECTIVE: Several artificial intelligence (AI) systems for diabetic retinopathy screening have been validated but there is limited evidence on their performance in real-world settings. This study aimed to assess the performance of an AI software deployed within the diabetic retinopathy screening programme in Dominica. METHODS AND ANALYSIS: We conducted a prospective, cross-sectional clinical validation study. Patients with diabetes aged 18 years and above attending the diabetic retinopathy screening in primary care facilities in Dominica from 5 June to 3 July 2021 were enrolled.Grading was done at the point of care by the field grader, followed by counselling and referral to the eye clinic. Images were then graded by an AI system. Sensitivity, specificity with 95% CIs and area under the curve (AUC) were calculated for comparing the AI to field grader as gold standard. RESULTS: A total of 587 participants were screened. The AI had a sensitivity and specificity for detecting referable diabetic retinopathy of 77.5% and 91.5% compared with the grader, for all participants, including ungradable images. The AUC was 0.8455. Excluding 52 participants deemed ungradable by the grader, the AI had a sensitivity and specificity of 81.4% and 91.5%, with an AUC of 0.9648. CONCLUSION: This study provides evidence that AI has the potential to be deployed to assist a diabetic screening programme in a middle-income real-world setting and perform with reasonable accuracy compared with a specialist grader.

The role of maternal age & birth order on the development of unilateral and bilateral retinoblastoma: a multicentre study.

BACKGROUND/OBJECTIVES: Retinoblastoma is a common childhood intraocular malignancy, the bilateral form of which most commonly results from a de novo germline pathogenic variant in the RB1 gene. Both advanced maternal age and decreasing birth order are known to increase the risk of de novo germline pathogenic variants, while the influence of national wealth is understudied. This cohort study aimed to retrospectively observe whether these factors influence the ratio of bilateral retinoblastoma cases compared to unilateral retinoblastoma, thereby inferring an influence on the development of de novo germline pathogenic variants in RB1. SUBJECTS/METHODS: Data from 688 patients from 11 centres in 10 countries were analysed using a series of statistical methods. RESULTS: No associations were found between advanced maternal age, birth order or GDP per capita and the ratio of bilateral to unilateral retinoblastoma cases (p values = 0.534, 0.201, 0.067, respectively), indicating that these factors do not contribute to the development of a de novo pathogenic variant. CONCLUSIONS: Despite a lack of a definitive control group and genetic testing, this study demonstrates that advanced maternal age, birth order or GDP per capita do not influence the risk of developing a bilateral retinoblastoma.

Perspectives on the provision of diabetic retinopathy screening: Survey of eye health care professionals in Haryana.

Purpose: To examine the current provision and practice patterns of diabetic retinopathy screening (DRS) in Haryana. Methods: This was a descriptive cross-sectional survey in Haryana. All ophthalmologists registered with Haryana Ophthalmological Society in Haryana state were invited to participate on an online survey comprised of twenty questions exploring diabetic retinopathy screening provision, and barriers to screening services in Haryana. Results: The response rate was 82% (153/186). The majority (84%) of the eye care providers practiced in urban areas. Most ophthalmologists (89%, 136/153), considered diabetic retinopathy screening by non-ophthalmic human resource inappropriate because of technical feasibility issues (62%) followed by non-availability of trained staff (33%). Only half (54%) of the respondents had access to written protocols for the diagnosis and management of diabetic retinopathy in their practice. Barriers to optimize diabetic retinopathy screening were lack of knowledge or awareness among patients (95.5%), perception that eye complications were unlikely (76%) and cost of care (30%). Conclusion: Diabetic retinopathy screening practices are mainly opportunistic and urban-centric, likely delivering inequitable services for the rural populations in the state. The inclusion of other personnel in screening will require stakeholder engagement from all health professions and changing the perceptions of ophthalmologists about task shifting.

Assistive technology for visual impairment and trainers at schools for the blind in Delhi.

The aim of the study was to assess the availability of assistive technology (AT) for visual impairment and trainers in schools for the blind in Delhi. A cross-sectional study was conducted in 22 of the 24 schools in Delhi. The headteacher of each school was asked about availability of 52 ATs divided into writing, reading, math, sciences, sports, mobility, and daily living, using a questionnaire. Information on availability of trainers was also collected. Of the 52 ATs, the most frequently available were Braille slate with stylus and abacus (>90% of schools), followed by Taylor frame, long cane and talking watch (80% to 90% of schools). Only 11 of 52 AT devices were available in 60% or more of the schools. Tactile-based ATs were more available than vision-based ATs. In the 22 schools, 63 trainers for reading & writing were available (80% of posts), 18 for sciences (59%), 25 for math (70%), and 11 for mobility (50% of posts). Except Braille slate and stylus, there is a huge shortage of AT in these schools. The educational needs and performance of students could be helped by developing and using a list of priority Assistive Products for example, the WHO AP list.

Waiting Time and Patient Satisfaction in a Subspecialty Eye Hospital Using a Mobile Data Collection Kit: Pre-Post Quality Improvement Intervention.

BACKGROUND: Waiting time can considerably increase the cost to both the clinic and the patient and be a major predictor of the satisfaction of eye care users. Efficient management of waiting time remains as a challenge in hospitals. Waiting time management will become even more crucial in the postpandemic era. A key consideration when improving waiting time is the involvement of eye care users. This study aimed at improving patient waiting time and satisfaction through the use of Plan-Do-Study-Act (PDSA) quality improvement cycles. OBJECTIVE: The objectives of this study were to determine the waiting time and patient satisfaction, measure the association between waiting time and patient satisfaction, and determine the effectiveness of the PDSA model in improving waiting time and satisfaction. METHODS: This was a pre-post quality improvement study among patients aged 19 to 80 years, who are consulting with the Magrabi International Council of Ophthalmology Cameroon Eye Institute. We used PDSA cycles to conduct improvement audits of waiting time and satisfaction over 6 weeks. A data collection app known as Open Data Kit (Get ODK Inc) was used for real-time tracking of waiting, service, and idling times at each service point. Participants were also asked whether they were satisfied with the waiting time at the point of exit. Data from 51% (25/49) preintervention participants and 49% (24/49) postintervention participants were analyzed using Stata 14 at .05 significance level. An unpaired 2-tailed t test was used to assess the statistical significance of the observed differences in times before and after the intervention. Logistic regression was used to examine the association between satisfaction and waiting time. RESULTS: In total, 49 participants were recruited with mean age of 49 (SD 15.7) years. The preintervention mean waiting, service, and idling times were 450 (SD 96.6), 112 (SD 47), and 338 (SD 98.1) minutes, respectively. There was no significant association between patient waiting time and satisfaction (odds ratio 1, 95% CI 0.99-1; P=.37; χ23=0.4). The use of PDSA led to 15% (66 minutes/450 minutes) improvement in waiting time (t47=2; P=.05) and nonsignificant increase in patient satisfaction from 32% (8/25) to 33% (8/24; z=0.1; P=.92). CONCLUSIONS: Use of PDSA led to a borderline statistically significant reduction of 66 minutes in waiting time over 6 weeks and an insignificant improvement in satisfaction, suggesting that quality improvement efforts at the clinic have to be made over a considerable period to be able to produce significant changes. The study provides a good basis for standardizing the cycle (consultation) time at the clinic. We recommend shortening the patient pathway and implementing other measures including a phasic appointment system, automated patient time monitoring, robust ticketing, patient pathway supervision, standard triaging, task shifting, physician consultation planning, patient education, and additional registration staff.
