When Is a Hospital Liable for a Doctor's Mistake?
Corporate negligence and ostensible agency mean a hospital can answer for a physician it never formally employed. What the doctrine actually requires — and how facilities can manage the exposure.
"Our doctors are independent contractors, so the hospital isn't liable." I hear that often, and as a starting point it's correct. As a conclusion, it's frequently wrong.
The default rule in Philippine practice is that an attending or consultant physician is an independent professional, not an employee — so a hospital is not automatically answerable for every act of every doctor who practices within its walls. But the Supreme Court has built two doctrines that reach past that default, and a hospital relying on the "contractor" label without understanding them is exposed without knowing it.
The default: the independent contractor
Most consultants are credentialed to practice at a hospital without being employed by it. They bill independently, exercise their own clinical judgment, and aren't subject to the hospital's control the way an employee is. On that basis, vicarious liability usually doesn't attach. Residents, fellows, and other staff the hospital actually employs are a different matter — for them, ordinary employer liability can apply.
The first bridge: ostensible agency
The first doctrine is apparent or ostensible agency — agency by estoppel. If a hospital holds a physician out to the public as though the doctor were its agent, and a patient reasonably relies on that in accepting treatment, the hospital may be estopped from later disowning the doctor. The classic case is the patient who comes to the institution — not to a doctor they chose — and is treated by whoever the hospital provides. In Nogales v. Capitol Medical Center and again in Professional Services, Inc. v. Agana, the Court found hospitals answerable on exactly this reasoning.
What creates the "holding out" is often mundane: signage, the hospital's name and logo, ID badges and uniforms, the absence of any clear notice that the doctor is independent. The patient sees the institution, not a businessperson renting space.
The second bridge: corporate negligence
The second doctrine is more direct, and for hospitals the more important. Under corporate negligence, a hospital owes duties to its patients in its own right — not derived from the doctor's fault at all. It must exercise reasonable care in selecting and credentialing the professionals it allows to practice, in supervising the care rendered in its facilities, and in maintaining systems adequate to protect patients. When it fails in those duties and a patient is harmed, the hospital answers for its own negligence. Professional Services, Inc. v. Agana is the leading Philippine statement of this principle — and it's why "the doctor was independent" is not, by itself, a defense.
What this means in practice
The exposure is real, but manageable — and the steps that manage it are the same steps that improve care. I advise hospitals to:
Make the independent-contractor relationship genuinely clear to patients — in admission and consent documents, and in practice, not just in a contract the patient never sees;
Credential and re-credential rigorously, and document it; the duty is to select competent practitioners and to act when there's reason for concern;
Supervise and monitor care through functioning committees, incident reporting, and follow-through, so that "systems adequate to protect patients" is true and provable;
Respond to adverse events in a way that preserves the facts and the institution's position, rather than improvising in the moment.
None of this makes a hospital an insurer of every outcome. What it does is line up the institution's actual conduct with the duties the law already imposes — so that if a claim comes, the hospital is defending what it did, not explaining what it failed to do.
