何に支えられ、何に崩されうるか
事業が頼っているもの
- 1A large share of testing is paid for by health plans and government programs, so payment rates, coverage rules and test-use policies affect revenue.
- 2Physician referrals and hospital relationships influence how much testing Quest receives; hospitals and physician groups may instead use their own laboratories.
- 3Laboratory testing depends on trained staff, collection and courier networks, laboratory equipment, supplies and information systems.
うまくいかなくなる可能性
- 1Medicare, Medicaid and commercial health plans may lower payment rates, limit covered tests or steer testing to selected providers, reducing revenue or payment per test.
- 2Hospitals and physician groups may bring more testing into their own laboratories, while commercial labs and new testing methods compete for referrals and patients.
- 3Errors in testing, failures to meet quality or regulatory requirements, or interruptions or security breaches in information systems could disrupt laboratory work and harm patient data or customer relationships.
