Background

Financial ties between physicians and the pharmaceutical and medical device industry are common, but little is known about how patient trust is affected by these ties.

Objective

The purpose of this study was to evaluate how viewing online public disclosure of industry payments affects patients' trust ratings for physicians, the medical profession, and the pharmaceutical and medical device industry.

Design

This was a randomized experimental evaluation.

Participants

There were 278 English-speaking participants over age 18 who had seen a healthcare provider in the previous 12 months who took part in the study.

Interventions

Participants searched for physicians on an online disclosure database, viewed payments from industry to the physicians, and assigned trust ratings. Participants were randomized to view physicians who received no payment ($0), low payment ($250-300), or high payment (>$13,000) from industry, or to a control arm in which they did not view the disclosure website. They also were asked to search for and then rate trust in their own physician.

Main measures

Primary outcomes were trust in individual physician, medical profession, and industry. These scales measure trust as a composite of honesty, fidelity, competence, and global trust.

Key results

Compared to physicians who received no payments, physicians who received payments over $13,000 received lower ratings for honesty [mean (SD): 3.36 (0.86) vs. 2.75 (0.95), p < 0.001] and fidelity [3.19 (0.65) vs. 2.89 (0.68), p = 0.01]. Among the 7.9% of participants who found their own physician on the website, ratings for honesty and fidelity decreased as the industry payment to the physician increased (honesty: Spearman's ρ = -0.52, p = 0.02; fidelity: Spearman's ρ = -0.55, p = 0.01). Viewing the disclosure website did not affect trust ratings for the medical profession or industry.

Conclusions

Disclosure of industry payments to physicians affected perceptions of individual physician honesty and fidelity, but not perceptions of competence. Disclosure did not affect trust ratings for the medical profession or the pharmaceutical and medical device industry.

Spurred on by recent health care reforms and the Triple Aim's goals of improving population health outcomes, reducing health care costs, and improving the patient experience of care, emphasis on population health is increasing throughout medicine. Population health has the potential to improve patient care and health outcomes for individual patients. However, specific population health activities may not be in every patient's best interest in every circumstance, which can create ethical tensions for individual physicians and other health care professionals. Because individual medical professionals remain committed primarily to the best interests of individual patients, physicians have a unique role to play in ensuring population health supports this ethical obligation. Using widely recognized principles of medical ethics-nonmaleficence/beneficence, respect for persons, and justice-this article describes the ethical issues that may arise in contemporary population health programs and how to manage them. Attending to these principles will improve the design and implementation of population health programs and help maintain trust in the medical profession.
