Abstract:Objective To investigate the effect of medication knowledge popularization on patients with differentiated thyroid cancer post-surgery.Methods A total of 100 patients who underwent thyroid cancer surgery between April 2020 and June 2021 were selected in this study and randomly divided into the observation group and the control group, each group with 50 patients. Patients in the control group received the standard health education, while those in the observation group received medication knowledge popularization intervention on the base of the control group. Comparison was made between the two groups based on Morisky Medication Adherence Scale (MMAS) scores at the first day of hospitalization and 6 months post-discharge, the percentage of patients with satisfied serum thyroid-stimulating hormone (TSH) levels at 1 month and 6 months post-discharge, tumor recurrence rate at one year after surgery, and the incidence rate of adverse drug reactions during treatment.Results There was no significant difference in MMAS scores between the two groups at the first day of hospitalization (P>0.05). However, at 6 months post-discharge, the MMAS scores of the observation group were significantly higher than those of the control group (P<0.05). At 1 month post-discharge, there was no significant difference in the percentages of patients with satisfied TSH levels between the two groups (P>0.05). But at 6 months post-discharge, the observation group had a higher percentage of patients who maintained TSH level at the recommended level than the control group (P<0.05). After 1 year of follow-up, no tumor recurrence was observed in the observation group, and there was less cases of adverse drug reactions observed in the observation group than in the control group.Conclusion The popularization of medication knowledge for thyroid cancer patients after surgery can improve their medication compliance, maintain their serum TSH levels in a recommended level, and reduce the incidence of tumor recurrence and adverse drug reactions.
