Evaluation of a Pharmacist-Led Levothyroxine Monitoring and Management Program at the Salisbury VA Health Care SystemAuthors: Kendra G. Hofler, Camille P. Robinette, Meghan Mark, and Aashish A. ShahBackground:Hypothyroidism is an endocrine disorder and can contribute to fatigue, weight gain, cognitive impairment, and cardiovascular complications if inadequately managed.1 Veterans are at increased risk for this disease due to certain environmental exposures, frequency of iodine exposure, and having post-traumatic stress disorder. 2-4 Appropriate levothyroxine dosing and regular thyroid function test (TFT) monitoring are essential for optimizing therapy, yet patients may experience delayed dose adjustments or overdue labs due to limited follow-up and provider workload. Pharmacist involvement in chronic disease management has demonstrated benefits in improving medication adherence, lab monitoring, and patient outcomes in various therapeutic areas.5 However, a structured, pharmacist-led hypothyroidism management process has not been formally implemented or evaluated at the Salisbury VA Health Care System (SVAHCS). The purpose of this quality improvement project is to assess the impact of pharmacist-led levothyroxine monitoring on treatment optimization, laboratory follow-up rates, and patient education within the SVAHCS.
Methods:This project will be conducted as a quality improvement initiative involving Veterans with a diagnosis of hypothyroidism and active levothyroxine prescription at the SVAHCS. Pharmacists will identify patients who are overdue for TFTs (>6 months) using population management tools within the Computerized Patient Record System (CPRS). Interventions will include recommending and/or ordering TFTs, evaluating laboratory results, making evidence-based dose adjustment recommendations, and providing patient education on proper levothyroxine administration (e.g., timing, drug–food interactions, and adherence). Pharmacists will also recommend endocrinology referral for complex or refractory cases. Primary outcomes will include the proportion of patients achieving euthyroid status (TSH within target range) and improvement in TFT follow-up compliance. Secondary outcomes will assess number of Veterans educated on proper levothyroxine administration, dosing, and side effects, number educated on signs and symptoms of hypothyroidism, and number of patients referred to endocrinology clinic. Data will be analyzed to determine the effectiveness and feasibility of pharmacist-led hypothyroidism management at the SVAHCS and to identify opportunities for broader implementation across the VA system.
Results:A total of 35 patients were included in the analysis, all of which received counseling on appropriate levothyroxine administration. Prior to intervention, 32 patients (91.4%) were identified as taking levothyroxine incorrectly. Pharmacist-led interventions were made in 9 cases (25.7%), including 3 dose decreases, 5 dose increases, and 1 discontinuation of levothyroxine therapy. Only 1 patient required referral to endocrinology for further management.
Discussion:The high proportion of patients taking levothyroxine incorrectly highlights a significant gap in patient understanding of proper administration, which may impact therapeutic outcomes. Pharmacist-led counseling appears to play an important role in identifying and addressing these issues. The relatively low number of medication interventions suggests that improper administration, rather than inappropriate dosing, may be a primary contributor to suboptimal therapy in this population. Additionally, the minimal need for endocrinology referral indicates that most patients can be effectively managed within a primary care or pharmacy setting.
Conclusion:This study demonstrates that incorrect levothyroxine administration is common among patients but can be effectively addressed through targeted counseling. Pharmacist involvement can improve medication use and optimize therapy, potentially reducing the need for specialist referral. Further studies are warranted to evaluate the long-term impact of counseling on clinical outcomes.
