Quality of life and decision regret in patients with late‐hypothyroidism after radioiodine treatment for Graves' disease

Abstract

AbstractObjectivePatients with Graves' disease often engage in shared decision‐making to select an individualised treatment regimen from multiple options. Radioactive iodine (RAI) is one of the treatment choices for their condition, aims to improve quality of life and well‐being. Likewise, dissatisfaction with treatment outcomes can result in decision regret. We employed validated questionnaires to assess the prospective quality of life, decision regret and relative factors involved in decision‐making of patients with late hypothyroidism after RAI therapy.MethodsA questionnaire survey was conducted among patients in hypothyroidism status for more than 1 year after RAI therapy. Disease‐specific and generic QoL were assessed using the short form of thyroid‐related patient‐reported outcome (ThyPRO‐39) questionnaire. Patient satisfaction regarding their decision to undergo RAI was assessed using the Decision Regret Scale (DRS) and patients were asked about the importance of relative factors in decision‐making.ResultsOf 254 patients who responded to the survey, the mean age of patients was 45.3 years (range: 18–78 years) and the median time from RAI therapy to survey was 4 years (range: 1–30 years). Patients' median and mean DRS score were 34.4 and 38.8 (range: 0–100), respectively. A total of 100 (39.4%) patients express absent‐to‐mild regret (score: 0–25), 154 (60.6%) patients express moderate‐to‐severe regret (score: >25). The mean score of the absent‐to‐mild regret group were significantly higher than those of the moderate‐to‐severe regret group on most ThyPRO‐39 scales. A statistically significant positive correlation was observed between DRS score and most ThyPRO‐39 scale score. There was a significant positive association between higher DRS score and longer time intervals after RAI treatment, a brief duration of hyperthyroidism, and the significance of long‐time outpatient follow‐up. More decision regret was negatively associated Iodine‐free diet, ineffectiveness of ATD, fear of surgery.ConclusionImpairment of quality of life was positively correlated with decision regret in patients with late‐hypothyroidism after radioiodine therapy. Patients with insufficient information support before decision‐making are more likely to have higher decision regret after treatment. Our findings suggest that health providers should fully communicate with patients and provide information support in multiple dimensions during the shared‐decision‐making process.
