Factors Associated With Attainment of Glycemic Targets Among Adults With Type 1 and Type 2 Diabetes in Canada: A Cross-sectional Study Using Primary and Specialty Care Electronic Medical Record Data

OBJECTIVE

Using a new database combining primary and specialty care electronic medical record (EMR) data in Canada, we determined attainment of glycemic targets and associated predictors among adults with diabetes.

METHODS

We conducted a cross-sectional observational study combining primary and specialty care EMR data in Canada. Adults with diabetes whose primary care provider contributed to the National Diabetes Repository or who were assessed at a diabetes specialty clinic (LMC Diabetes and Endocrinology) between July 3, 2015, and June 30, 2019, were included. Diabetes type was categorized as type 2 diabetes (T2D) not prescribed insulin, T2D prescribed insulin, and type 1 diabetes (T1D). Covariates were age, sex, income quintile, province, rural/urban location, estimated glomerular filtration rate, medications, and insulin pump use. Associations between predictors and the outcome (glycated hemoglobin [A1C] of ≤7.0%) were assessed by multivariable logistic regressions.

RESULTS

Among 122,106 adults, consisting of 91,366 with T2D not prescribed insulin, 25,131 with T2D prescribed insulin, and 5,609 with T1D, attainment of an A1C of ≤7.0% was 60%, 25%, and 23%, respectively. Proportions with an A1C of ≤7.5% and ≤8.0% were 75% and 84% for those with T2D not prescribed insulin, 41% and 57% for those with T2D prescribed insulin, and 37% and 53% for those with T1D. Highest vs lowest income quintile was associated with greater odds of meeting the A1C target (adjusted odds ratio [95% confidence interval] for each diabetes category: 1.15 [1.10 to 1.21], 1.21 [1.10 to 1.33], and 1.29 [1.04 to 1.60], respectively). Individuals in Alberta and Manitoba had less antihyperglycemic medication use and attainment of A1C target than other provinces.

CONCLUSIONS

Attainment of glycemic targets among adults with diabetes was poor and differed by income and geographic location, which must be addressed in national diabetes strategies.

Training the Next Generation of Diabetes Researchers: Evaluation of the Diabetes Action Canada Training and Mentoring Program

BACKGROUND

The Diabetes Action Canada Training and Mentoring (DAC-TM) Program launched in June 2017, with the goal of building capacity in the next generation of diabetes researchers in Canada in patient-oriented research (POR).

METHODS

We conducted a program evaluation of the DAC-TM program using a sequential, mixed-methods research design.

RESULTS

Our analysis of 82 surveys and 22 in-depth interviews from a wide range of DAC-TM Program stakeholders revealed consistent patterns in experience with the program. The training sessions were perceived to be well-organized, convenient educational opportunities to gain new knowledge about POR and become integrated into a community of practice of POR researchers who study diabetes and its complications in Canada. The content of the training was perceived to be useful and relevant to participants, although improvements could be made to help address the training needs of the broader DAC community. There is broad support for and appreciation of the mentorship awards, which were perceived to be appropriately targeted to early-career investigators. The mentor-mentee relationships were perceived to be positive, productive and career-advancing overall, but could benefit from a more strategic design and promote better connectivity to foster mentor-mentee relationships. In addition, feedback about opportunities to network and forge new connections was mixed and represents another opportunity for improvement to strengthen capacity building.

CONCLUSIONS

Findings from this formative evaluation study show key strengths and opportunities to improve the DAC-TM Program, which can be used to help enhance its function and promote its long-term sustainability.

Prevalence and health effects of communicable and non-communicable disease comorbidity in rural KwaZulu-Natal, South Africa

OBJECTIVES

To describe changes in prevalence of hypertension, diabetes, HIV and tuberculosis, and prevalence of comorbidity, and to investigate associations between each condition, and combinations of conditions, with self-reported general health and hospital admission.

METHODS

This study used data from a longitudinal population-based HIV and health surveillance cohort, conducted by the Africa Health Research Institute in Umkhanyakude district of rural KwaZulu-Natal, South Africa.

RESULTS

Prevalence of hypertension, HIV and diabetes increased from 2009 to 2015, and prevalence of tuberculosis decreased. 81% of the 47 334 participants were female; hypertension and diabetes were the commonest conditions in people over age 50, whereas HIV was most common in those younger than 50 years. Comorbidity of communicable and non-communicable conditions was commonest in 40- to 60-year-olds. The adjusted odd ratios (OR) for better self-reported general health with multimorbidity were 0.53 (95% CI 0.51-0.56), 0.29 (95% CI 0.27-0.29), 0.25 (95% CI 0.21-0.37) and 0.21 (95% CI 0.12-0.37) for one, two, three and four conditions, respectively, vs. no conditions. Tuberculosis was most strongly and inversely associated with better general health (OR 0.34 (0.31-0.37) and most strongly associated with hospital admission (OR 3.26 (2.32-2.99)).

CONCLUSION

The high prevalence of communicable and non-communicable conditions in this rural South African population is giving rise to a burden of multimorbidity, as increased access to antiretroviral treatment has reduced mortality in people with HIV. Healthcare systems must adapt by working towards integrated primary care for HIV/AIDS and non-communicable diseases.

Stock-outs of essential health products in Mozambique - longitudinal analyses from 2011 to 2013

OBJECTIVES

To assess the relationship between health system factors and facility-level EHP stock-outs in Mozambique.

METHODS

Service provisions were assessed in 26 health facilities and 13 district warehouses in Sofala Province, Mozambique, from July to August in 2011-2013. Generalised estimating equations were used to model factors associated with facility-level availability of essential drugs, supplies and equipment.

RESULTS

Stock-out rates for drugs ranged from 1.3% for oral rehydration solution to 20.5% for Depo-Provera and condoms, with a mean stock-out rate of 9.1%; mean stock-out rates were 15.4% for supplies and 4.1% for equipment. Stock-outs at the district level accounted for 27.1% (29/107) of facility-level drug stock-outs and 44.0% (37/84) of supply stock-outs. Each 10-km increase in the distance from district distribution warehouses was associated with a 31% (CI: 22-42%), 28% (CI: 17-40%) or 27% (CI: 7-50%) increase in rates of drug, supply or equipment stock-outs, respectively. The number of heath facility staff was consistently negatively associated with the occurrence of stock-outs.

CONCLUSIONS

Facility-level stock-outs of EHPs in Mozambique are common and appear to disproportionately affect those living far from district capitals and near facilities with few health staff. The majority of facility-level EHP stock-outs in Mozambique occur when stock exists at the district distribution centre. Innovative methods are urgently needed to improve EHP supply chains, requesting and ordering of drugs, facility and district communication, and forecasting of future EHP needs in Mozambique. Increased investments in public-sector human resources for health could potentially decrease the occurrence of EHP stock-outs.
