Knowledge gaps and perceptions of future research directions on management of diabetes during Ramadan fasting: An online survey of physicians

A Systematic Review of Insulin Management Recommendations to Improve Glycemic Control and Reduce Hypoglycemic Events During Ramadan Fasting in Patients With Insulin-Requiring Type 2 Diabetes

Background

Muslims with insulin-requiring type 2 diabetes are at high risk of hypo- and hyperglycemia while fasting during the month of Ramadan. Although a few reviews on diabetic management during Ramadan have been published, surveys reveal knowledge gaps remain among physicians.

Aim

This systematic review qualitatively analyzes what insulin dosing recommendations are likely to reduce hypoglycemic events and improve glycemic control during the Ramadan fasting for this high-risk group.

Methods

A comprehensive search in six databases and gray sources was performed from August 10, 2001, to August 10, 2021, for studies assessing which types of insulin and/or what dosing recommendations reduce hypoglycemic events and improve glycemic control during Ramadan. We excluded studies focusing mainly on oral antihyperglycemic medications, type 1 diabetes, persons with insulin pumps, and studies older than 20 years. Hypoglycemic event rates, pre-, and post-iftar blood glucose levels, overall average blood glucose, and hemoglobin A1c were analyzed, and a narrative synthesis was performed.

Results

Out of 1,101 collected articles, 14 eligible studies including 2,969 participants with an average age of 54.8 years, we found that insulin dose reduction may prevent hypoglycemia without causing subsequent hyperglycemia, and rapid-acting insulin analogs may improve post-iftar and overall blood glucose without incurring hypoglycemia.

Conclusions

Though initial findings are promising, more research is needed to confirm the benefits of insulin dose reduction, rapid-acting insulin analogs, and ultra-long-acting insulins.

Comprehensive Care for Patients with Diabetes in Ramadan: A Module for Pharmacy Students and Pharmacists

Introduction

Prior studies show that many patients with diabetes whose health maybe impacted by fasting, choose to fast during Ramadan. This study describes the implementation and evaluation of an online module targeting bachelor of pharmacy (BPharm) and doctor of pharmacy (PharmD) students that aims to improve participants' knowledge, communication, and self-efficacy concerning proper care for patients with diabetes in Ramadan.

Methods

An online module consisting of two phases targeting both BPharm and PharmD students was implemented over two semesters in fall 2020 and spring 2021. Participants were directed to fill pre-module and post-module assessments to evaluate the change in their knowledge and self-efficacy using two scales. Pre- and post-survey data for participants’ knowledge and self-efficacy were analyzed for significance using paired sample t-tests. Qualitative data analysis was performed to assess participants’ responses to the open-ended question concerning what they liked and disliked about the module.

Results

All BPharm and PharmD students taking the lesson responded to both the baseline survey and the follow-up one resulting in 92 responses (participation rate of 100%). The average score for participants in the pre-module self-efficacy section was 1.5 (SD = 1) and increased post-module to 3.5 (SD = 0.7), t (91) = 20.2, p < 0.001. Further, the average score for participants in the pre-module knowledge section was 14 (SD = 3), which similarly increased to 22 (SD = 3) post-module t (91) = 19.7, p < 0.001. Qualitative analysis provided insights on how participants perceived the module design, content, and its impact on practice. Participants described the module as an informative one that addresses a much-needed issue they haven’t been exposed to before. They emphasized how the module addresses the cultural needs of patients in their communities. They particularly appreciated seeing instructor videos depicting real-life scenarios and the focus on their communication skills, but some preferred learning about this topic through live sessions.

Conclusion

An online module positively impacted both self-efficacy and knowledge in relation to caring for patients with diabetes considering fasting in Ramadan. Future studies should explore how different versions of this module can be integrated into educational activities for pharmacy students, pharmacists in different settings, and for other health care professionals.

Ramadan Fasting and Maternal and Fetal Outcomes in Pregnant Women with Diabetes Mellitus: Literature Review

There is an emerging Muslim and diabetic population in the United States and other Western countries and majority of pregnant women and patients with diabetes mellitus choose to fast during Ramadan. Fasting during Ramadan in pregnant women with diabetes may represent a 'perfect storm' of metabolic disturbances including hyperglycemia, hypoglycemia and ketosis. Recent continuous and flash glucose monitoring data suggests increased glycemic variability (fasting hypo- and post-Iftar hyperglycemia) in non-pregnant patients with diabetes during Ramadan. Only five small-scale studies, predominantly focused on women with gestational diabetes mellitus in Muslim-majority nations have explored maternal glycemic outcomes during Ramadan which is associated with lower mean blood glucose levels and higher frequency of fasting hypoglycemia. Data is limited however on important clinical outcomes such as symptomatic and serious hypoglycemia requiring hospitalization. Results have been conflicting regarding maternal Ramadan fasting and association with fetal outcomes in women without diabetes. Only one recently published study reported on perinatal outcomes in pregnant women with gestational diabetes which found no effect of Ramadan exposure on mean birthweight or macrosomia frequency but lower neonatal hypoglycemia prevalence, however a significant limitation was lack of documentation of maternal fasting status. At this stage, due to paucity of data, the current medical recommendation is against Ramadan fasting for pregnant Muslim women with diabetes. Large-scale population-based studies are warranted regarding maternal and fetal outcomes in pregnant fasting women with diabetes and such studies should characterize maternal fasting status and have meaningful and consistent clinical outcomes. High-quality data derived from these studies can assist clinicians in providing more evidence-based advice to safely navigate both mother and fetus through a potentially challenging pregnancy.
