Plain English Summary

Background and study aims
Women with breast cancer want to participate in treatment decision making. SDM includes a mutual decision making process between patients and healthcare professionals considering all relevant information on treatment options and patients´ preferences. It enables patients to make informed decisions. Up to now implementation of SDM has failed due to e.g. limited resources of physicians and lack of evidence-based decision aids. We developed an SDM programme for women with primary ductal carcinoma in situ (DCIS). It includes an evidence-based patient decision aid, training of specialized breast care and oncology nurses, workshop for physicians, and decision coaching for women. The programme aims at supporting involvement in decision making and informed choices.
In this study we investigate if women receiving evidence based decision aids and decision coaching by specialised nurses will be more involved in treatment decision making than women receiving standard care.

Who can participate?
Women are eligible if they are at least 18 years old, have no known BRCA1/2-mutation, are not pregnant and have a primary DCIS. All participants need sufficient German language skills.

What does the study involve?
The trial compares the SDM programme with standard care. 16 certified breast care centres will be included recruiting 192 women with primary DCIS. Two study groups (intervention and control group) are compared. The intervention includes a four day training programme in SDM for specialised nurses, a two hour-lasting workshop in SDM for physicians and an evidence-based patient decision aid and decision coaching for women. Women in the control group receive standard care.

What are the possible benefits and risks of participating?
It is expected that the provision of an evidence-based patient decision aid combined with decision coaching will increase women´s involvement in decision making and informed choices. The intervention will reduce women’s decisional conflicts and the duration of physician encounters. We expect no harm for participating women.

Where is the study run from?
The study will include 16 certified breast care centres in the following federal states of Germany: Schleswig-Holstein, Hamburg, Bremen, North Rhine-Westphalia, Hessen, Saxony-Anhalt, Mecklenburg-West Pomerania and Lower Saxony.

When is the study starting and how long is it expected to run for?
October 2014 to March 2016

Scientific titleInformed shared decision making supported by decision coaches for women with ductal carcinoma in situ: a cluster-randomized-controlled trial
Study acronymSPUPEO
Study hypothesisThe main hypothesis is that patients facing a primary treatment decision on ductal carcinoma in situ (DCIS) who receive an evidence-based decision aid combined with decision coaching by specialized nurses are more involved in treatment decision making compared to patients receiving standard care. The extent of physicians’, patients’ and nurses’ shared decision making-behaviour will be assessed using the observer-based rating of the `multifocal approach to the sharing in shared decision making´ (MAPPIN-SDM). In addition, we hypothesize that in the intervention group informed choices will increase, decisional conflict will decrease and the duration of physician consultations will be shortened.

ConditionBreast cancer, ductal carcinoma in situ, primary treatment decision, shared decision making
Intervention1. Intervention group: SPUPEO programme comprising:
1.1. Evidence-based decision aid on the primary treatment of ductal carcinoma in situ
1.2. Nurse training (four days divided into two modules)
1.3. Workshop for physicians (two hours) and
1.4. At least one decision coaching session for the participating patients.
2. Control group: The health care professionals in the control group receive no intervention and will deliver standard care.
Intervention typeOther
Primary outcome measureThe primary outcome is defined as the extent of informed shared decision making-behaviour (SDM-behaviour) of physicians, nurses and patients during the consultations and the decision coaching sessions. We will measure SDM-behaviour using the observer based instrument MAPPIN-O of the “multifocal approach to the ‘sharing’ in shared decision-making” (MAPPIN). It assesses the mutual SDM-behaviour of health care professionals and patients based video-recordings. In the control group the physician consultations will be rated, whereas in the intervention group nurse and physician encounters will be summed up. All ratings will be performed independently by two trained observers.
Secondary outcome measures1. Observer based rating of SDM-behaviour of patients alone (MAPPIN-Opatient)
2. Observer based rating of SDM-behaviour of physicians alone (MAPPIN-Ophysician)
3. Observer based rating of SDM-behaviour of nurses alone (MAPPIN-Onurses)
4. Patient based judgment about perceived SDM-behaviour
5. Nurse based judgment about perceived SDM-behaviour (only in the intervention group)
6. Physician based judgment about perceived SDM-behaviour
7. Concordance between professionals (nurses or physicians) and patient based judgment of SDM-behaviour
8. Informed choice (including the three subdimensions attitude, knowledge and uptake)
9. Decisional conflict
10. Duration of consultations
