RESUMO
Primary hypothyroidism, the most common form of hypothyroidism, requires effective patient understanding and management for successful long-term treatment. This study aimed to investigate the influence of patient knowledge, attitude, practice (KAP), depression, and medication adherence on treatment response in primary hypothyroidism. A cross-sectional observational study was conducted at Al Hassan Metabolism, Endocrine, and Diabetes Center (HMEDC) in Iraq between September 2022 and March 2023. We enrolled 111 patients with signs and symptoms of primary hypothyroidism over 6 months. A validated questionnaire assessed patient knowledge, attitude, practice (KAP), depression, and medication adherence. Thyroid-stimulating hormone (TSH) levels were measured to assess treatment response. Data were analyzed using SPSS v26, with categorical variables presented as percentages. The student's t-test was used to assess statistical significance, with P - valuess below 0.05 considered significant and P - values below 0.01 considered highly significant. The mean age of patients was 45 ± 11.9 years. Approximately 34% of patients had insufficient knowledge, and 30% indicated a positive attitude towards their treatment. A total of 35% of patients had excellent practice. There was no statistically significant association between KAP and age or gender. There was a significant positive correlation between higher levels of education and improved KAP scores. A total of 44.1% of participants reported moderate depression, and 58% demonstrated adherence to levothyroxine (LT4) treatment. Despite good adherence, the combination of fair knowledge and moderate-to-severe depression resulted in suboptimal outcomes for replacement treatment.
