This study investigated whether providing a document template for patients to describe their values and preferences to their physician improves shared decision making when deciding to start a new medication. The study found that the template did not significantly reduce decision conflict or regret, but did increase agreement between the physician's recommendation and the patient's final decision. It also increased the rate of patients carefully considering the physician's opinion rather than immediately agreeing or refusing. The template may enhance dialogue and encourage patients to consider their physician's professional advice.

2. Background and Purpose
• Although there are several decision-support tools for
empowering patients at Shared Decision Making (SDM),
their effectiveness is limited.
• We have developed a document template for patients to
describe their own values and preferences, etc., in the
context of making a decision with their physician to start
drug medication.
• We investigated if any conflict in the decision process, the
decision making and the patient’s own decision could be
influenced by giving a written document with patient’s
preferences and values to her/his physician.

16. Discussion
• Templates were not significantly associated with Decision
Conflict or Decision Regret after the decision agenda was
introduced. Communicating patient’s preferences and
situations to his/her physician does not affect the conflicts and
regrets of the decisions made.
• Templates may have promoted awareness of interactive
context. With understanding beyond yes-no answer, the
patient may eventually choose a medically recommended
option.
• Physicians who read the template may have made adherence
and professional recommendations for patient preferences.
17. CONCLUSION
SUBMITTING WRITTEN DOCUMENTS
WITH PATIENT'S VALUES TO HIS/HER
PHYSICIAN IN ADVANCE OF A CLINICAL
DECISION MAKING MAY ENHANCE THE
DIALOGUE PROCESS ON SDM AND MAY
ENCOURAGE THE PATIENT TO
CAREFULLY LISTEN TO HIS/HER
PHYSICIAN’S PROFESSIONAL OPINION.
18. Abstract
• Purpose: Although there are several decision-support tools for empowering patients at Shared Decision Making
(SDM), their effectiveness is limited. We have developed a document template for patients to describe their own
values and preferences, etc., in the context of making a decision with their physician to start drug medication. We
investigated if any conflict in the decision process, the decision making and the patient’s own decision could be
influenced by giving a written document with patient’s preferences and values to her/his physician.
• Method: We examined a comparative study before and after setting a control period and an intervention period.
Study targets were patients who were in a situation where their physicians were considering the commencement
of any new antihypertensive, antihyperlipid or diabetes agents. For study intervention, there was a single-sheet
template that provided spaces to describe the following; patient’s worry; expectation of outcomes; expectation of
the efficacy of the medicine; self-care plan; things want to be avoid. The documented template was attached to
the electronic medical record so that the patient's physician could read it before the next consultation. A chart
review of the medical record after 3 months of registration examined the content of the actual decision and the
degree of agreement between the doctor's recommended option at the patient registration and the decision
actually made. We also compared the mean values of the Decision Conflict Scale (DCS) and the Decision Regret
Scale (DRS) two months after the study registration.
• Result: Seventy-nine controls and 73 intervention groups participated in the study. The mean value of the DCS in
the control and intervention groups was 35.3 ± 12.2, 38.9 ± 17.1 (p = 0.19) and 21.8 ± 12.6, 22.0 ± 14.5 (p =
0.96) for the DRS. Three months after registration, the percentage of those who started the drug, those who did
not start, and those who delayed their decision to start in the control group were 39%, 49%, and 11%, respectively.
While in the intervention group, it was 47%, 28%, and 24%, respectively (p = 0.015). Seventy-five percent of
controls and 89% of the intervention group were in agreement with the recommendations that their physicians
had in mind regarding the decision to take medications at the time of the patient’s registration.
• Conclusion: Submitting written documents with patient's values to his/her physician in advance of a clinical
decision making may enhance the dialogue process on SDM and may encourage the patient to carefully listen to
his/her physician’s professional opinion.
