Role of 24-hour Helpline Service in the Management of Diabetes During the Holy Month of Ramadan

Objective To assess the role of the 24-hour helpline service in the management of diabetes during the holy month of Ramadan. Methodology This prospective study was conducted at the Baqai Institute of Diabetology & Endocrinology, Baqai Medical University, Karachi, Pakistan, between December 2017 and August 2018. Patients with type 1 and type 2 diabetes who were willing to observe the fast in Ramadan 2018 were included. Pre-Ramadan education on a one-to-one basis was given and the 24-hour helpline number was provided to each patient. Details of baseline characteristics, anthropometric measurements, and biochemical parameters (lipid profile, serum creatinine, urine D/R (protein), and glycated hemoglobin A1c pre- and post-Ramadan) were noted. Self-monitoring blood glucose (SMBG) recording books were provided to each patient to record blood sugar levels during Ramadan. Results A total of 102 patients, 41 (40.2%) with type 1 diabetes and 61 (59.8%) with type 2 diabetes were included. The mean age of patients with type 1 diabetes was 17.02±5.22 years and that of patients with type 2 diabetes was 49.48±9.68 years. Most of the patients were male in both groups. By using the 24-hour helpline service, 912 calls were made to patients, 502 calls for type 1, and 410 calls for type 2 diabetes. Mean HbA1c (%) level before and after Ramadan was 8.94±1.72 and 8.70±2.03 in patients with type 1 diabetes and 8.59±1.73 and 7.71±1.27 in patients with type 2 diabetes, respectively. In the last 10 days of Ramadan, the decreasing trends of mean self-monitoring of blood glucose (SMBG) in patients with type 1 diabetes was observed for pre-dawn meal (suhoor), pre-sunset meal (iftar), and before sleeping while this trend in type 2 diabetes was found in the pre-dawn meal (suhoor)and two hours after iftar. Conclusion Pre-Ramadan diabetes education and treatment adjustment by using a station-based, 24-hour helpline service during the holy month of Ramadan have a significant role in controlling blood sugar levels, thus minimizing the complications of diabetes, facilitating timely adjustments in treatment, and reducing unnecessary hospital visits and admissions.


Introduction
Diabetes is one of the most alarming public health issues, especially for lower-middle-income countries [1]. In Pakistan, 7.5 million people have diabetes as reported by the International Diabetes Federation (IDF) atlas [2]. A recent second National Diabetes Survey of Pakistan (NDSP 2016(NDSP -2017 has estimated that the prevalence of diabetes is 26.3% [3]. Fasting (abstaining from food and drink from dawn to sunset) during the month of Ramadan is one of the five main pillars of Islam [4]. Most Muslims are passionate about fasting during this month, although sick people are exempted. However, many diabetics may not perceive themselves as sick and a high proportion fasts [5][6]. A large epidemiology study of Muslims with diabetes in 13 Islamic countries -the Epidemiology of Diabetes and Ramadan (EPIDAR) study -showed 43% of patients with type 1 and 79% of those with type 2 diabetes fasting during Ramadan [7].
Patients with diabetes who intend to fast should have proper knowledge to fast and receive counseling about change in medication timings and dose, dietary changes, and the role of SMBG in order to avoid developing acute complications [8]. Diabetes is a condition that requires constant monitoring and adjustments of medication, resulting in frequent visits to the clinic. To minimize these visits and provide ongoing support, a system is available in the form of the 24-hour helpline service. This is an easily accessible and low-cost medium, which is considered an effective alternative [9]. If prompt advice is given, the frequency of complications can be significantly reduced, leading to a decrease in morbidity and mortality [10].
In Karachi, Pakistan, the Baqai Institute of Diabetology and Endocrinology (BIDE), Baqai Medical University (BMU), pioneered the concept of a station-based 24-hour helpline service in 1996. A randomized trial was conducted to determine the effect of helpline service intervention on HbA1c in patients with diabetes from rural areas of Pakistan, which showed a significant improvement in HbA1c levels [9]. To the best of our knowledge, no such records were found for managing diabetes during Ramadan at the national and international levels. Therefore, the aim of our study is to assess the role of the 24-hour helpline service in the management of diabetes during the holy month of Ramadan.

Materials And Methods
This prospective study was conducted at BIDE-BMU, a tertiary care diabetes unit in Karachi, Pakistan. The duration of the study was from December 2017 to August 2018. Ethical approval for the study was obtained by the Institutional Review Board (IRB) of BIDE. Informed consent was obtained from each study participant. Patients with type 1 and type 2 diabetes who were willing to observe the fast in Ramadan 2018 were included. Patients with poorly controlled type 1 and type 2 diabetes, a history of diabetic ketoacidosis in the last two months, pregnant women with diabetes, and those who were not willing to observe the fast were excluded from the study.
Baseline demographic parameters (gender, age, marital status, smoking habit, duration of diabetes, family history of diabetes) and anthropometric measurements (body mass index (BMI) and systolic and diastolic blood pressure) were obtained. Details of biochemical parameters, including the lipid profile, serum creatinine, urine D/R (protein), and glycated hemoglobin A1c of pre-and post-Ramadan were also recorded. Pre-Ramadan diabetes education related to blood glucose targets, self-monitoring blood glucose (SMBG), nutrition, medication regimens, insulin handling, hypoglycemia, hyperglycemia, alteration of insulin dose, diet changes during Ramadan. Diabetes self-management education on a one-to-one basis was given to each patient. The 24-hour helpline service has been functioning at BIDE since 1996 and is facilitating its registered patients through qualified and trained diabetes educators. Each participant was provided the 24-hour helpline number for queries and support regarding their medical conditions. SMBG recording books were provided to study participants, and they were asked to record their blood glucose level before the pre-dawn meal (suhoor), two hours after suhoor, at mid-day, before the pre-sunset meal (iftar), two hours after iftar, before sleeping, and at any time when the symptoms of hypoglycemia/hyperglycemia or acute illnesses occur during Ramadan. Each patient was given a call by the helpline service (every fifth day of Ramadan) and SMBG records were noted. Calls were also received from patients for their arising complaints and were facilitated with appropriate advice. All data were collected through the health management system (HMS) of BIDE.
Patients were guided to break the fast, if they felt unwell, or if their blood glucose reached <70 mg/dL (3.9 mmol/L) or >300 mg/dL (16.7 mmol/L) [11]. Glycemic control was assessed by checking HbA1c one month before the start of Ramadan and one month after the end of Ramadan using the high-performance liquid chromatography (HPLC) method on Bio-Rad D-10 (Bio-Rad Laboratories, Inc., Hercules, CA). To determine triglycerides, the glucose oxidasephenol and phenol + aminophenazone (GOD-PAP) method on a fully automated analyzer was used. Serum total cholesterol was analyzed by the cholesterol oxidase and phenol + aminophenazone (CHOD-PAP) method on Selectra Pro S (ELITech Group SAS, Puteaux • France), a fully automated analyzer. The homogeneous enzymatic colorimetric method was used for high-density lipoprotein (HDL) cholesterol and the direct method used for low-density lipoprotein (LDL) cholesterol measurement. Nephropathy was defined as protein > 1+ on dipstick (Combur 10, Roche Diagnostics, Basel, Switzerland) with no other abnormal findings on urinary examination [12]. Height was measured to the nearest 0.1 cm, with the subject standing in the erect posture, and weight was measured with a portable weighing scale to the nearest 0.1 kg. Body mass index (BMI) was measured as the ratio of weight (kg) to height squared (m2). As per Asian guidelines, people having BMI ≥ 25 (kg/m2) were labeled obese [13]. The blood pressure of the participants was monitored by the mercury sphygmomanometer in a sitting position by using the standard method. Hypertension was defined as blood pressure ≥140/90mmHg [11].

Statistical analysis
Data were analyzed using Statistical Package for Social Sciences (SPSS), version 20.0 (IBM Corp. Armonk, NY). The student's t-test, chi-square test, paired t-test, and two proportion ztest were used where applicable. Continuous variables were presented as mean ± SD. Similarly, categorical variables were presented in the form of numbers and percentages. Pvalue <0.05 was considered statistically significant.

and type 2 diabetes
Data presented as mean ± SD or n (%); *p-value < 0.05 was considered statistically significant Student's t-test and chi-square test were applied.   Data presented as mean ± SD; P-value < 0.05 was considered as statistically significant.
Paired t-test was applied.
HbA1c: glycated hemoglobin Figure 1, Figure 2, and Figure 3 show the trends of mean SMBG readings during the first 10 days, the second 10 days, and the last 10 days of Ramadan at different meal timings between both groups. Blood glucose level readings were noted by most of the patients (96%) during Ramadan. In the last 10 days of Ramadan, decreasing trends of mean SMBG in patients with type 1 diabetes were observed for pre-Seher, pre-Iftar, and post-dinner while this trend in type 2 diabetes was found for pre-Seher and post-Iftar.  Figure 4 shows the frequency of incoming and outgoing calls to both types of diabetics during Ramadan. A total of 912 calls was made to patients using the 24-hour helpline service. Out of which, type 1 calls were 527 (57.7%) -462 outgoing calls and 65 incoming calls. Type 2 calls were 385 (42.21%) -a total of 370 outgoing calls and 15 incoming calls.
