Development of a four-day service-learning rotation for third-year medical students.

Background: Despite the proven benefits of service-learning, its use in medical school curricula has been inconsistent. The effect of service-learning on students' primary care residency choices is largely unknown.

Description: Fifty-three students completed a 4-day service-learning experience, which included homeless clinics, homeless shelter, and street outreach, then completed surveys and wrote reflection essays.
