Establishment of a Decision Aid Tool for Asymptomatic Small Leiomyoma and Analysis of Influencing Factors for Clinical Decision-making Using HIFU

Study Overview
=================
Brief Summary
-----------------
With the younger patients diagnosed with asymptomatic leiomyoma, delay in the reproductive age of women, the advancement of medical technology, and the rapid development of treatment methods, there are many choices between gynecologists, gynecologists and patients because of experience and knowledge. It is not easy to make the most favorable choice for patients. This study is mainly led by a committee composed of designers, doctors, nurses and patients, and based on clinical guidelines and evidence-based medicine. Co-operating with patients with asymptomatic small leiomyoma, we want to find the influencing factors of clinical decision-making, and to establish a patient decision aid tool. We use prospective trial to verify that the use of this tool can improve patients' decision-making efficacy and further improve patient-reported outcomes.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| communication without PADs<br>We use traditional communication ways to discuss the conditions with patients. | |
| communication with PADs<br>The committee, composed of designers, doctors, nurses and patients, bases on guidelines and evidence-based medicine to make a tool. And we use this tool to discuss the conditions with patients. | Other: Patients Decision Aids<br>* Patient Decision Aids (PDAs) are an important way to facilitate making decision by patients, helping patients make specific and prudent choices by providing information about treatment options and corresponding outcomes, including benefits and risks, related to their health status. The purpose of PDAs is to encourage patients to participate in decision-making. It makes it easier for patients and doctors to discuss treatment options. It effectively promotes communication between patients and doctors. It can help patients combine their own needs and professional advice to make better, more individualized diagnosis and treatment options.<br>|
