Ethical Information Transparency and Sexually Transmitted Infections

Area of Science:

• Medical Ethics
• Health Psychology
• Decision Science

Background:

• Shared decision-making (SDM) aims to balance patient autonomy and beneficence.
• Information sharing in SDM presents challenges regarding transparency and potential for subtle manipulation.
• Paternalistic strategies, or 'nudges,' can influence patient choices.

Purpose of the Study:

• To investigate the impact of message framing on patient judgments in SDM.
• To evaluate the effectiveness of decision aids and additional information in mitigating framing effects.
• To explore the influence of nudges versus non-nudging interventions on decision-making.

Main Methods:

• Two experiments were conducted with participants (N=146 and N=492).
• Experiment 1 examined the effect of positively vs. negatively framed messages on surrogate designation decisions for an HIV patient.
• Experiment 2 replicated findings and tested the impact of providing additional information on surrogate decision-making accuracy.

Main Results:

• Positively framed messages significantly increased the likelihood of judging that a patient with HIV should designate a surrogate compared to negatively framed messages.
• A simple decision aid did not consistently reduce this framing effect.
• Providing additional information about surrogate decision-making accuracy reduced the tendency to believe a surrogate designation was necessary.

Conclusions:

• Framing effects (nudges) can influence patient judgments in ways that simple decision aids do not.
• While nudges can be persuasive, non-nudging interventions, like providing comprehensive information, are generally preferable for preserving patient autonomy.
• Careful consideration of information transparency and persuasion tactics is crucial in SDM.
