The cost and cost efficiency of conducting a 24-h dietary recall using INDDEX24, a mobile dietary assessment platform, compared with pen-and-paper interview in Viet Nam and Burkina Faso.

The INDDEX24 Dietary Assessment Platform (INDDEX24) was developed to facilitate the collection of 24-h dietary recall (24HR) data. Alongside validation studies in Viet Nam and Burkina Faso in 2019-2020, we conducted activity-based costing studies to estimate the cost of conducting a 24HR among women of reproductive age using INDDEX24 compared with the pen-and-paper interview (PAPI) approach. We also modelled alternative scenarios in which: (1) 25-75 % of dietary reference data were borrowed from the INDDEX24 Global Food Matters Database (FMDB); (2) all study personnel were locally based and (3) national-scale surveys. In the primary analysis, in Viet Nam, the 24HR cost US $111 004 ($755/respondent, n 147) using INDDEX24 and $120 483 ($820/respondent, n 147) using PAPI. In Burkina Faso, the 24HR cost $78 105 ($539/respondent, n 145) using INDDEX24 and $79 465 ($544/respondent, n 146) using PAPI. In modelled scenarios, borrowing dietary reference data from the FMDB decreased the cost of INDDEX24 by 17-34 % (Viet Nam) and 5-15 % (Burkina Faso). With all locally based personnel, INDDEX24 cost more than PAPI ($498 v. $448 per respondent in Viet Nam and $456 v. $410 in Burkina Faso). However, at national scales (n 4376, Viet Nam; n 6500, Burkina Faso) using all locally based personnel, INDDEX24 was more cost-efficient ($109 v. $137 per respondent in Viet Nam and $123 v. $148 in Burkina Faso). In two countries and under most circumstances, INDDEX24 was less expensive than PAPI. Higher INDDEX24 survey preparation costs (including purchasing equipment) were more than offset by higher PAPI data entry, cleaning and processing costs. INDDEX24 may facilitate cost-efficient dietary data collection.

Increasing Incidence of Type 1 and Type 2 Diabetes Among Canadian Children.

BACKGROUND: Diabetes mellitus is one of the most common pediatric chronic illnesses. Although a rising incidence of childhood type 1 diabetes (T1D) has frequently been documented, an almost 400-fold variation in incidence has been seen worldwide. We aimed to describe the trends in incidence of diabetes (type 1, type 2, all types) among children and adolescents living in the Greater Montréal area of Québec, Canada. METHODS: Using health administrative data (Québec Integrated Chronic Disease Surveillance System) and medical records from the 3 major pediatric diabetes centres in the Greater Montréal area, we conducted serial cross-sectional studies of children aged 1 to 15 years during the period from 2002 to 2010. We conducted a trend analysis of diabetes incidence over time using multivariate Poisson regression models. RESULTS: We identified 696 new cases of diabetes between 2002 and 2010. The age-standardized incidence of diabetes (all types) increased from 16.3 (95% confidence interval [CI], 12.4 to 21.2) to 27.8 (95% CI, 22.5 to 34.0) per 100,000, with annual incidence increasing, on average, by 5.2% per year (adjusted rate ratio [aRR], 1.052; 95% CI, 1.022 to 1.083). This was driven predominantly by the T1D annual increase of 5.4% (aRR, 1.054; 95% CI, 1.023 to 1.086). A low number of incident cases of type 2 diabetes limited trend analysis in this group. There were no significant interactions between year and sex or age. CONCLUSIONS: The annual incidence of T1D is increasing in Québec children and does not vary by sex or age. Further research into etiologic factors is indicated.

Validation of the INDDEX24 mobile app v. a pen-and-paper 24-hour dietary recall using the weighed food record as a benchmark in Burkina Faso.

Effective nutrition policies require timely, accurate individual dietary consumption data; collection of such information has been hampered by cost and complexity of dietary surveys and lag in producing results. The objective of this work was to assess accuracy and cost-effectiveness of a streamlined, tablet-based dietary data collection platform for 24-hour individual dietary recalls (24HR) administered using INDDEX24 platform v. a pen-and-paper interview(PAPI) questionnaire, with weighed food record (WFR) as a benchmark. This cross-sectional comparative study included women 18-49 years old from rural Burkina Faso (n 116 INDDEX24; n 115 PAPI). A WFR was conducted; the following day, a 24HR was administered by different interviewers. Food consumption data were converted into nutrient intakes. Validity of 24HR estimates of nutrient and food group consumption was based on comparison with WFR using equivalence tests (group level) and percentages of participants within ranges of percentage error (individual level). Both modalities performed comparably estimating consumption of macro- and micronutrients, food groups and quantities (modalities' divergence from WFR not significantly different). Accuracy of both modalities was acceptable (equivalence to WFR significant at P < 0·05) at group level for macronutrients, less so for micronutrients and individual-level consumption (percentage within ±20 % for WFR, 17-45 % for macronutrients, 5-17 % for micronutrients). INDDEX24 was more cost-effective than PAPI based on superior accuracy of a composite nutrient intake measure (but not gram amount or item count) due to lower time and personnel costs. INDDEX24 for 24HR dietary surveys linked to dietary reference data shows comparable accuracy to PAPI at lower cost.

Identifying pediatric diabetes cases from health administrative data: a population-based validation study in Quebec, Canada.

BACKGROUND: Type 1 diabetes is one of the most common chronic diseases in childhood with a worldwide incidence that is increasing by 3-5% per year. The incidence of type 2 diabetes, traditionally viewed as an adult disease, is increasing at alarming rates in children, paralleling the rise in childhood obesity. As the rates of diabetes increase in children, accurate population-based assessment of disease burden is important for those implementing strategies for health services delivery. Health administrative data are a powerful tool that can be used to track disease burden, health services use, and health outcomes. Case validation is essential in ensuring accurate disease identification using administrative databases. AIM: The aim of our study was to define and validate a pediatric diabetes case ascertainment algorithm (including any form of childhood-onset diabetes) using health administrative data. RESEARCH DESIGN AND METHODS: We conducted a two-stage method using linked health administrative data and data extracted from charts. In stage 1, we linked chart data from a large urban region to health administrative data and compared the diagnostic accuracy of various algorithms. We selected those that performed the best to be validated in stage 2. In stage 2, the most accurate algorithms were validated with chart data within two other geographic areas in the province of Quebec. RESULTS: Accurate identification of diabetes in children (ages ≤15 years) required four physician claims or one hospitalization (with International Classification of Disease codes within 1 year (sensitivity 91.2%, 95% confidence interval [CI] 89.2-92.9]; positive predictive value [PPV] 93.5%, 95% CI 91.7-95.0) or using only four physician claims in 2 years (sensitivity 90.4%, 95% CI 88.3-92.2; PPV 93.2%, 95% CI 91.7-95.0). Separating the physician claims by 30 days increased the PPV of all algorithms tested. CONCLUSION: Patients with child-onset diabetes can be accurately identified within health administrative databases providing a valid source of information for health care resource planning and evaluation.

Improving the transition from pediatric to adult diabetes care: the pediatric care provider's perspective in Quebec, Canada.

OBJECTIVES: The transition from pediatric to adult care is a high-risk period for the emerging adult with diabetes. We aimed to determine adequacy of pediatric transition care structures and explore the pediatric diabetes care provider's perceptions of transition care. RESEARCH DESIGN AND METHODS: In-depth interviews with pediatric diabetes care providers from 12 diabetes centers in Quebec were conducted. We queried alignment with Got Transition's six core elements of healthcare transition, experiences, and barriers to transition care. Interview transcripts were reviewed for themes. RESULTS: Three centers (25%) reported having any elements of formal and structured transition care preparation and planning. When referrals were within center (n=8), pediatric providers perceived that transition was smoother; information sharing relied heavily on verbal communication rather than documented medical summaries. Barriers included lack of adult providers, less flexibility in adult care scheduling, patient struggles with multiple new adult responsibilities, and insufficient understanding by adult providers of these challenges. There was a perception that the quality of pediatric care was better than adult care. Moving out of the pediatric care geographical region appeared to increase risk for poor follow-up. Patient satisfaction and regular follow-up in adult care were thought to be good measures of transition success. Programs that included overlap between pediatric and adult care were perceived as ideal. CONCLUSIONS: Important gaps in transition care practices persist. Efforts should focus on improving education in transition practices for pediatric care providers and establishing formal transition policies and structures at the institutional level.

Experiences of caregivers of children with inherited metabolic diseases: a qualitative study.

BACKGROUND: We sought to understand the experiences of parents/caregivers of children with inherited metabolic diseases (IMD) in order to inform strategies for supporting patients and their families. We investigated their experiences regarding the management of disease, its impact on child and family life, and interactions with the health care system. METHODS: From four Canadian centres, we conducted semi-structured telephone interviews with parents/caregivers of children with an IMD who were born between 2006 and 2015 and who were participating in a larger cohort study. Participants were selected with the aim of achieving a diverse sample with respect to treatment centre, IMD, and age of the child. Interviews emphasized the impacts of the disease and its treatment on the child and family and explicitly queried perceptions of interactions with the health care system. We identified emergent themes from the interview data. RESULTS: We completed interviews with 21 parents/caregivers. The 21 children were aged <1 to 7 years old with IMD that included amino acid disorders, urea cycle disorders, fatty acid oxidation disorders, and organic acid disorders or 'other' IMD. Most parents reported that they and their families had adapted well to their child's diagnosis. Parents used proactive coping strategies to integrate complex disease management protocols into routine family life. An important source of stress was concern about the social challenges faced by their children. Participants reported positive interactions with their most involved health care providers within the metabolic clinic. However, they reported challenges associated with the health care system outside of disease-specific metabolic care, when encountering systems and providers unfamiliar with the child's disease. CONCLUSIONS: The successful use of proactive coping strategies among parents of children with IMD in this study suggests the potential value of promoting positive coping and is an important direction for future study. Parents' social concerns for their children were important stressors that warrant consideration by health care providers positioned to support families. Our results with respect to experiences with care highlight the important role of specialized metabolic clinics and point to a need for better coordination of the care that takes place outside the disease-specific management of IMD.

Improving the Transition from Pediatric to Adult Diabetes Healthcare: A Literature Review.

Effective transition to adult care is a significant component of an emerging adult's diabetes care. Poor transition places them at risk for disengagement with the health care system and for poor diabetes-related outcomes. The purpose of this paper was to review the literature to date on existing methods of transition care delivery for emerging adults with diabetes. We conducted a literature review using MEDLINE via OvidSP and searching the grey literature. Papers published in English between January 1, 2000 and March 25, 2015 that evaluated transition care programs for emerging adults with diabetes were included. 16 original studies, 1 study protocol and 1 technical brief describing transition programs were reviewed. Common components of care included transition care coordination, young adult clinics, transition preparation, familiarity with adult health care providers and support groups. Overall, when emerging adults are supported during the transition period, clinic attendance and glycemic control can be maintained or improved, and diabetes-related complications reduced. Despite widespread support in the literature for the need for structured transition care delivery, methodologically strong research evaluating transition care services remains limited. The literature to date encompasses a variety of care models that lack consistency in outcome measurements as well as lacking frameworks describing the interventions, which impedes comparison across studies. Further research, using a consistent framework for transition care program design, delivery and evaluation as well as reporting of outcomes, is needed to inform how best to deliver transition care services to this vulnerable population.
