Creating a Stronger Healthcare Community.

Supporting Providers and Their Patients

• Governance - We strive to always have a seat at the table where decisions are being made, specifically as those choices relate to the unique circumstances facing independent community providers.
•  Advocacy - We are a voice representing and advocating for independent practices, providing support and facilitation to resolve issues.
•  Communication - We assume the role of “translator,” clarifying communications to our independent providers. We keep them informed on critical issues and provide analyses and/or syntheses of external or key communications,
•  Performance - We aim to benefit POSS members and their patients, IDN, and the South Shore Health System. We coordinate with and support IDN's efforts and facilitate improved provider performance (quality and total medical cost).  
•  Practice Support - We're providing an arena for our members to share critical insights about their administrative and patient-care best practices, and supporting our members directly through vendor discounts, resource synthesizing, and practice advocacy.

Founded in 1995, POSS is governed by a Board of Directors comprised of local community physicians serving the South Shore of Massachusetts.

POSS providers are affiliated with South Shore Health System and other hospitals. Partnering together, POSS primary care physicians and specialist physicians have built strong relationships and share best practices to drive quality care for the greater healthcare community.

In 2021, POSS realigned our structure to enhance the deep connection with independent community physicians.

POSS provider membership is now focused on independent practices that serve the local community of the South Shore of Massachusetts. Currently, POSS has over 35 practices with over 100 local providers, primary care physicians, and specialists, all of whom are dedicated to providing exemplary medical care for their patients.

POSS local primary care physicians work collaboratively with local specialists to refer their patients to colleagues, collectively contributing to quality care and a better patient experience.
