Summary

Background and Rationale:

Vitamin D deficiency is a major public health concern. While clinical guidelines provide treatment protocols, medication adherence remains a significant barrier to achieving target serum levels. This study aims to evaluate whether a structured patient education program can improve health beliefs and adherence, ultimately leading to better clinical outcomes.

Study Procedures:

Participants identified with Vitamin D levels \<30 ng/mL will be randomized into two groups.

Intervention Group:

Patients will receive a face-to-face education session covering the importance of Vitamin D, correct usage, and potential side effects. They will also receive informative brochures and monthly follow-up phone calls to support adherence.

Control Group:

Patients will receive standard clinical care without additional structured education.Evaluation:Adherence will be monitored using the Medication Possession Ratio (MPR). Serum 25(OH)D levels and Vitamin D Health Belief Scale scores will be reassessed at the 3-month mark to compare the effectiveness of the intervention against the control group.

Conditions

Interventions

BEHAVIORAL

Educational with vitamin D

This study implements a pharmacist-led patient education program designed to improve treatment adherence and health beliefs in individuals with vitamin D deficiency (25(OH)D \< 30 ng/mL). The intervention begins with the collection of sociodemographic data and the administration of the Vitamin D Health Belief Scale to establish a baseline. The core intervention involves providing the intervention group (n=30) with structured oral counseling and written educational materials (patient brochures) regarding the clinical importance and proper usage of vitamin D. In contrast, the control group receives standard care. Three months post-intervention, follow-up assessments are conducted via telephone to re-evaluate health beliefs and measure treatment adherence using the Medication Possession Ratio (MPR). The primary success criteria are achieving an MPR ≥ 8
