Physician related barriers towards insulin therapy at primary care centres in Trinidad: a cross-sectional study

A Hybrid Model of In-Person and Telemedicine Diabetes Education and Care for Management of Patients with Uncontrolled Type 2 Diabetes Mellitus: Findings and Implications from a Multicenter Prospective Study

Background

Patients with uncontrolled type 2 diabetes mellitus (T2DM) require close follow-up, support, and education to achieve glycemic control, especially during the initiation or intensification of insulin therapy and self-care management. This study aimed to describe and evaluate the impact of implementing a hybrid model of in-person and telemedicine care and education on glycemic control for patients with uncontrolled T2DM (hemoglobin A1c [HbA1c] ≥9%) during the coronavirus disease pandemic.

Methods

This prospective multicenter-cohort pre-/post-intervention study was conducted on patients with uncontrolled T2DM. This study included three chronic illness centers affiliated with the Family and Community Medicine Department at Prince Sultan Military Medical City in Riyadh, Saudi Arabia. A hybrid model of in-person (onsite) and telemedicine care and education was developed. This involved implementing initial in-person care at the physicians' clinic and initial in-person education at the diabetes education clinic, followed by telemedicine services of tele-follow-ups, support, and education for an average 4-month follow-up period.

Results

Of the enrolled 181 patients, more than half of the participants were women (n = 103, 56.9%). The mean age of participants (standard deviation) was 58.64 ± 11.23 years and the mean duration of diabetes mellitus was 13.80 ± 8.55 years. The majority of the patients (n = 144; 79.6%) were on insulin therapy. Overall, in all three centers, the hybrid model had significantly reduced HbA1c from 10.47 ± 1.23% to 7.87 ± 1.59% (mean difference of reduction 2.59% [95% confidence interval (CI) = 2.34-2.85%], p < 0.001). At the level of each center, HbA1c was reduced significantly with mean differences of 3.17% (95% CI = 2.81-3.53%), 2.49% (95% CI = 1.92-3.06%), and 2.16% (95% CI = 1.76-2.57%) at centers A, B, and C, respectively (all p < 0.001).

Conclusion

The findings showed that the hybrid model of in-person and telemedicine care and education effectively managed uncontrolled T2DM. Consequently, the role of telemedicine in diabetes management could be further expanded as part of routine diabetes care in primary settings to achieve better glycemic control and minimize nonessential in-person visits when appropriate.

Barriers and Attitudes of Primary Healthcare Physicians to Insulin Initiation and Intensification in Saudi Arabia

Saudi Arabia is a country with high prevalence of diabetes, uncontrolled diabetes, and diabetes-related complications. Poor glycemic control is multifactorial and could be explained in part by physician and patient reluctance toward insulin or insulin inertia. This study aimed to address physician barriers toward insulin therapy in primary care settings. It included 288 physicians from 168 primary healthcare centers (PHC) in the Jazan region of Saudi Arabia. Participants responded to questionnaire investigating physicians' attitude and barriers to insulin initiation and intensification in PHCs. In physician opinion, the most common barriers among their patients were fear of injection, lack of patient education, fear of hypoglycemia, and difficult administration. Physicians were reluctant to initiate insulin for T2D patients mostly due to patient non-adherence to blood sugar measurement, non-adherence to appointment or treatment, elderly patients, or due to patient refusal. Physicians' fear of hypoglycemia, lack of staff for patient education, and lack of updated knowledge were the primary clinician-related barriers. Exaggerated fears of insulin side effects, patient non-adherence, limited staff for patient's education, patient refusal, and inadequate consultation time were the main barriers to insulin acceptance and prescription.
