Insights

Pharmacist-involved collaborative care significantly improved glycated haemoglobin (HbA1c) in Type 2 diabetes patients. Health education and medication adjustments were key drivers of this improvement.

Area of Science:

  • Endocrinology
  • Pharmacotherapy
  • Cardiovascular Medicine

Background:

  • Type 2 diabetes management requires continuous monitoring of glycated haemoglobin (HbA1c).
  • Pharmacist-involved collaborative care (PCC) models are emerging as a strategy to improve patient outcomes.
  • The association between PCC, clinical activities, and HbA1c changes needs further elucidation.

Purpose of the Study:

  • To evaluate the change in HbA1c in patients receiving PCC compared to cardiologist care (CC).
  • To identify clinical activities associated with HbA1c improvement.
  • To explore moderators influencing the PCC-HbA1c relationship.

Main Methods:

  • Retrospective cohort study of 420 adults with Type 2 diabetes and cardiovascular disease over 12 months.
  • 1:1 matching of PCC patients with CC patients based on baseline HbA1c.
  • Linear mixed models and linear regression analyzed HbA1c changes and associated clinical activities.

Main Results:

  • The PCC group showed a significant mean HbA1c decrease of -0.4% at 6 and 12 months, compared to -0.1% and -0.2% in the CC group (P<0.001).
  • Higher frequencies of lifestyle counseling, health education, medication adherence reinforcement, and problem resolution were observed in the PCC group (P<0.001).

Conclusions:

  • Pharmacist-involved collaborative care leads to significant improvements in HbA1c for Type 2 diabetes patients.
  • Health education and medication adjustments are critical components driving HbA1c reduction within PCC.
  • PCC offers a valuable model for enhancing diabetes management and cardiovascular health.

Diabetes: Management and Pharmacotherapy

The therapy for diabetes aims to alleviate hyperglycemia-related symptoms, prevent acute metabolic decompensation, and reduce chronic end-organ complications. Glycemic control is evaluated through short-term (self-monitoring, continuous glucose monitoring) and long-term (A1c, fructosamine) metrics, enabling near real-time tracking of blood glucose levels and reflecting glycemic control over specific time frames.
Insulin remains the cornerstone of treatment for most patients with type 1 and many...
