About this study

Official title: Effectiveness of a Patient Decision Aid for Patients With Superficial Basal Cell Carcinoma: a Pre- and Post-implementation Study

A patient decision aid (PDA) was tested in a population of patients with superficial basal cell carcinoma. This study evaluates whether the use of a PDA improved outcomes like decisional conflict and knowledge.

Read the detailed description

Background Patients with a superficial basal cell carcinoma (sBCC) can choose between several treatment options with specific advantages and disadvantages. A patient decision aid (PDA) might facilitate a personalized decision.

Objectives This study evaluates whether the use of a PDA results in a decreased level of decisional conflict, improved satisfaction with the treatment decision, and increased knowledge on prevention, recognition of BCC, and treatment options.

Methods A prospective multicentre pre- and post-implementation study was performed amongst patients with a newly diagnosed sBCC comparing a group that did not use the PDA (control group) with a group that did (PDA group). The primary outcome was the level of decisional conflict measured by the total mean score on the 'decisional conflict scale' (DCS) directly before treatment. Higher scores correspond with higher levels of decisional conflict (scale 0-100). Knowledge of disease and treatment options was evaluated by using a questionnaire.

Results Questionnaires were completed by 103 patients in the control group and 109 patients in the PDA group. The mean total score on the DCS in the control group was 22.78 (SD 14.76) compared to 22.34 (SD 14.54) in the PDA group. The adjusted mean difference was -0.39 (95% CI -4.47-3.70, p=0.851). Cohen's effect size for the total score on the DCS was 0.03. Use of the PDA resulted in a significant increase of knowledge on recognition of BCC (p<0.001) and treatment options for sBCC (p=0.005). According to exploratory subgroup analyses the unadjusted mean difference in DCS score was higher in patients with sBCC in the head and neck area (-4.53, p=0.378), patients without a history of BCC (-3.76, p=0.251), and patients with higher educational level (-4.71, p=0.196).

Conclusion In the total study population with newly diagnosed sBCC, use of a PDA increased knowledge on relevant issues, but had no significant effect on the level of decisional conflict when compared with a control group. Exploratory subgroup analyses suggest that specific subgroups of patients may benefit from the use of a PDA, but these results need to be verified in larger studies.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Decisional conflict

    The primary outcome was the level of decisional conflict measured by the total mean score on the 'decisional conflict scale' (DCS) directly before treatment. Higher scores correspond with higher levels of decisional conflict (scale 0-100).

    Measured: Before treatment

Secondary outcomes (2)
  1. Knowledge

    To evaluate patient knowledge, we used a questionnaire adapted by our research group from a knowledge assessment for melanoma. [14, 15] (Appendix B) The questionnaire included items on sun-protection (7 statements), risk factors for developing a BCC (10 statements), treatment options for sBCC (7 statements), and ways to recognize a BCC (6 statements). The proportions of patients with correct answers (true/false) for all statements within a domain were compared between the two groups.

    Measured: Before treatment

  2. Patient satisfaction

    Patient satisfaction with treatment decision was measured using the mean scores on the subscale 'effective decision making' and separate questions of this subscale of the DCS at 3 months post-treatment

    Measured: 3 Months post-treatment

Questions about this trial

What is this clinical trial studying?

An observational study of Superficial Basal Cell Carcinoma, run by Maastricht University Medical Center at 1 site in Netherlands.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 Nov 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Decisional conflict (time frame: Before treatment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Nov 2022.
