Brief summary
This behavioral clinical trial assesses the efficacy of a educational intervention to increase shared decision making about prostate-specific antigen (PSA)-based screening for prostate cancer among African American males. Half of participants will receive a multimedia educational intervention, while the other half will receive usual care.
Detailed description
The 2018 U.S. Preventive Services Task Force (USPSTF) final recommendation states that male patients and their providers engage in a shared-decision making process about the benefits and harms of PSA-based screening. As characterized by the USPSTF, these conversations are particularly important for African American men given increased ambiguity due to the lack of PSA-based research specific to this population and increased risk of prostate cancer mortality attributed to late stage at diagnosis and more aggressive prostate cancer phenotypes seen in African American men. The goal of this randomized behavioral clinical trial is to advance the translation path of implementing the decision-making process in clinical encounters by evaluating the efficacy of an educational intervention for African American males to increase shared decision making about PSA-screening versus usual care. The intervention will use multimedia educational training materials to increase understanding of prostate cancer, PSA-based screening, and shared decision making among patients and their primary care providers (PCPs).
Interventions
The intervention includes a web-based patients' decision aid about PSA-based prostate cancer screening, risks and preferences. The providers receive a summary of the USPSTF 2018 guidelines and main components of the Agency for Healthcare Research and Quality (AHRQ) SHARE curriculum, a link to a video of a prototypical shared decision making conversation, and a laminated shared decision making reminder card.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Shared Decision-making | One month after audio-recorded visit | The Observing Patient Involvement (OPTION) Scale was used for the coding of the SDM. The total OPTION scale ranges from 0 to 48. Higher values on the scale mean higher patient involvement in the decision-making process. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Quality of Decision (QD) | Up to 24 weeks after the audio-recorded visit | The total QD score ranges from 0 to 100. Higher percentage scores mean higher quality of the decision made. |
| Preference-Congruent Decision Making | Through study completion, an average of 1 year | The Intention-to-Screen score ranges from 0 to 1. Score = 0 means no intention to receive the PSA test while score = 1 means intention to receive the PSA test. Preference-concordant decision making will be scored as 1 (POSITIVE) for those patients with Intention-to-Screen value = 1 who actually receive the PSA test during the study timeframe, or for those patients with Intention-to-Screen value = 0 who did not receive it. Preference-concordant decision making will be scored as 0 (NEGATIVE) for those patients with Intention-to-Screen value = 1 who did not receive the PSA test during the study timeframe, or for those patients with Intention-to-Screen value = 0 who did receive it. A congruence score of 1 means congruence between patient intention and real action, while a congruence score of 0 means patient in congruence between intention and real action. |

| Measure | Time frame | Description |
|---|---|---|
| Acceptability | Through study completion, an average of 1 year | Participants complete a structured questionnaire to rate the acceptability of the enrollment process, study procedures, and their overall satisfaction with the study. The score ranges from 10 to 50. Higher scores mean higher acceptability of study procedures. |

Outcome results
Shared Decision-making
The Observing Patient Involvement (OPTION) Scale was used for the coding of the SDM. The total OPTION scale ranges from 0 to 48. Higher values on the scale mean higher patient involvement in the decision-making process.
Time frame: One month after audio-recorded visit
Population: The OPTION Scale was applied only to patients who had attended the medical appointment (62 in the intervention group, and 64 in the control group). Because one recording in the control group could not be completed (the audio-recording device was damaged), only 63 recordings were evaluated in that group.
| Arm | Measure | Value (MEAN) | Dispersion |
|---|---|---|---|
| Intervention | Shared Decision-making | 12.54 Units on a scale | Standard Deviation 11.0198 |
| Usual Care | Shared Decision-making | 12.15 Units on a scale | Standard Deviation 10.4026 |
Preference-Congruent Decision Making
The Intention-to-Screen score ranges from 0 to 1. Score = 0 means no intention to receive the PSA test while score = 1 means intention to receive the PSA test. Preference-concordant decision making will be scored as 1 (POSITIVE) for those patients with Intention-to-Screen value = 1 who actually receive the PSA test during the study timeframe, or for those patients with Intention-to-Screen value = 0 who did not receive it. Preference-concordant decision making will be scored as 0 (NEGATIVE) for those patients with Intention-to-Screen value = 1 who did not receive the PSA test during the study timeframe, or for those patients with Intention-to-Screen value = 0 who did receive it. A congruence score of 1 means congruence between patient intention and real action, while a congruence score of 0 means patient in congruence between intention and real action.
Time frame: Through study completion, an average of 1 year
Population: Congruence was assessed only for patients who completed the follow-up (60 in the intervention group, and 53 in the control group).
| Arm | Measure | Group | Value (NUMBER) |
|---|---|---|---|
| Intervention | Preference-Congruent Decision Making | Participants with Congruence Score = 1 | 36 Number of participants |

Quality of Decision (QD)
The total QD score ranges from 0 to 100. Higher percentage scores mean higher quality of the decision made.
Time frame: Up to 24 weeks after the audio-recorded visit
Population: The QD was assessed only for patients who completed the follow-up (60 in the intervention group, and 53 in the control group).
| Arm | Measure | Value (MEAN) | Dispersion |
