From toy to tool: Using water beads for insulin storage in Haiti.

Diabetes prevalence within the global population has nearly doubled since 1980, with the most rapid growth occurring in low- and middle-income countries. Diabetes management in resource-limited settings such as Haiti presents many challenges, including the storage of insulin. Despite a lack of published data on insulin thermostability, storage at 2-8°C or at room temperature (25°C) is recommended. In Haiti, access to refrigeration and thereby proper insulin storage is severely limited. Commercial storage devices such as the FRIO cooling wallet are cost-prohibitive and not available locally, and alternatives such as small clay pots are fragile and nonportable. Here, we designed and tested the cooling efficacy of a homemade wallet made of acrylate polymer beads and a hand-sewn cotton pouch compared to a FRIO wallet and a clay pot. All studies were conducted over a ten-day period at the Kay Mackenson Clinic in Montrouis, Haiti. Temperature and humidity values were continuously collected using wireless monitors placed inside each device, and hourly ambient temperature and humidity values were manually recorded. Evaporative cooling efficacy was calculated using collected data. The homemade wallet and FRIO cooling wallet demonstrated comparable cooling efficacy with an average of 71% and 73%, respectively. The clay pot demonstrated significantly decreased efficacy with an average of 27% (p < 0.05). The homemade insulin wallet is a promising alternative for the storage of insulin in low-resource settings without the financial and physical barriers of commercial and locally sourced devices. Additionally, this wallet could be readily adapted for the storage of other perishable medical supplies in low-income countries.

High rates of ocular complications in a cohort of Haitian children and adolescents with diabetes.

BACKGROUND: Ophthalmic complications of pediatric diabetes are rare, and rates are unknown in Haitian youth. OBJECTIVES: To determine the prevalence and predictors of diabetic retinopathy (DR) and cataracts in a cohort of Haitian youth with insulin-treated diabetes. METHODS: We performed a cross-sectional retrospective review of pediatric patients with diabetes from a pediatric chronic disease center in Haiti, from December 1, 2012 to November 1, 2016. Data collection included demographic and anthropometric information, total daily insulin dose and result of eye examination by a local ophthalmologist. RESULTS: Of 67 patients (54% female, mean age at diagnosis 14.6 ± 3.9 years, mean diabetes duration 3.3 ± 3.0 years, mean HbA1c 84 ± 22 mmol/mol (9.8% ± 2.0%), mean current insulin requirement 0.49 ± 0.28 IU/kg/day), DR was diagnosed in 10/57 (18%) and cataracts in 10/62 (16%), at a mean age of 19.0 ± 4.3 and 19.1 ± 3.3 years, respectively. Diabetes duration was 4.9 ± 5.4 and 3.0 ± 1.5 years at the time of diagnosis of DR and cataracts, respectively. Age at complication, insulin requirement, sex, body mass index, family history, mean HbA1c and diabetes duration were not significant predictors of an ocular complication. CONCLUSIONS: In this cohort of Haitian youth, DR and cataracts occur prematurely. Low-insulin requirements years after diagnosis, possibly allowing for prolonged undetected hyperglycemia prediagnosis, may explain complication risk. The phenotypes of diabetes in pediatric populations of African ancestry may be distinct. Ophthalmologic evaluation should possibly start at diagnosis, and screening guidelines may need to be adapted.

Validation Study and Outcomes of the Diabetes Quality of Life in Youth Instrument in Haitian Youth With Type 1 Diabetes Residing in Haiti.

OBJECTIVES: Health-related quality of life (HRQL) in type 1 diabetes is a critical health outcome but has not been studied in many low-income countries. In this study we evaluated the validity of 2 HRQL instruments, measured the HRQL and explored the association between HRQL and glycemic control. METHODS: This was a cross-sectional study of Haitian youth with diabetes between 0 and 25 years of age and living in Haiti. We administered the 51-item Diabetes Quality of Life for Youth (DQOLY) questionnaire and the EuroQol Visual Analogue Scale (EQ-VAS). Psychometric analyses evaluated internal consistency and construct validity of the DQOLY and its 21-item short form, the DQOLY-SF. Linear regression was used to identify predictors of HRQL and glycated hemoglobin (A1C). RESULTS: In 85 youth (59% female; mean age, 17.5 years; mean diabetes duration, 3.7 years; mean A1C, 11.3%), DQOLY and DQOLY-SF had adequate internal consistency with Cronbach's alpha values of 0.86 and 0.84, respectively. Confirmatory factor analysis revealed adequate validity for the DQOLY-SF and DQOLY Satisfaction subscale. HRQL, as measured using the DQOLY-SF, was 62±16 (mean ± standard deviation) out of 100. Mean EQ-VAS score was 78±24 out of 100. Older age (p=0.004), female sex (p=0.02) and lower socioeconomic status (SES) (p=0.03) were risk factors for lower DQOLY score, and older age (p=0.02) and marginally female sex (p=0.06) for lower DQOLY-SF score. No predictors of EQ-VAS were identified. HRQL measures were not associated with glycemic control. CONCLUSIONS: The DQOLY-SF and DQOLY Satisfaction subscale are valid measures of HRQL in Haitian youth with diabetes. HRQL is low and was worse in older, female and low-SES youth, but was not associated with glycemic control.

Valuation of Life With Disability: An International Comparison Study in Vietnam, Peru, and Haiti.

The authors measured perceived quality of life for 4 disabilities among 450 adults in 3 resource-limited countries, measuring mean utilities using time trade-off, and surveying participants on 35 sociocultural characteristics to compare utilities for disabilities by country and examine associated sociocultural characteristics. Mean utilities were >0 for mild and moderate, but <0 for severe and profound. Utilities differed across countries (P = .007, .000, .017, .000 for mild, moderate, severe, profound, respectively). Vietnamese utilities correlated with residence (P = .03, moderate), education (P = .03, severe), and number of children (P = .03, moderate). Peruvian utilities correlated with education (P = .05, mild; P = .05, severe), experience with disability (P = .001, mild), gender (P = .04, moderate; P = .03, profound), number of hospitalizations (P = .04, severe). In Haiti, the only correlate was rejection (P = .02, moderate). Culture-specific variables differentially shape perceptions of disability in developing countries, thereby affecting cost-effectiveness calculations. Given substantially negative perceptions, reducing major disability would improve cost-effectiveness of health-policy decisions more than reducing mortality.
