Finally, hospitals may be held liable for failing to protect patients from harm, adequately perform clinical tests, keep accurate medical records, and properly admit and discharge patients. In the area of admissions, hospitals are generally required to treat seriously injured or ill people on an emergency basis, and the refusal to do so may result in hospital liability. Additionally, federal and state statutes prohibit hospitals from refusing to treat or admit people based on their race, color, religion or national origin, or on their inability to pay for treatment.

Vicarious Liability

When a hospital employee's malpractice injures a patient, the hospital itself may be held vicariously liable under the legal doctrine of "respondeat superior." Under this doctrine, an employer may be held liable for the negligent acts of its employee, if the employee was acting within the scope of his or her employment when the negligent act or omission occurred. This doctrine is very important to plaintiffs in medical malpractice cases, because it helps ensure there will be a financially responsible party to compensate an injured plaintiff.

In some situations, health care providers such as physicians are considered independent contractors rather than hospital employees, and the doctrine of "respondeat superior" will not be applicable. What this means is, if a doctor or other health care professional is an independent contractor, and commits malpractice while treating a patient in a hospital, the hospital cannot be held liable for the doctor's negligence. However, the hospital can be held liable for its own negligence, for example, in granting attending privileges to an unlicensed or incompetent physician.

Finally, in certain situations, a hospital may be vicariously or directly liable for the acts or omissions of contractors it retains to operate emergency rooms and outpatient facilities.

Pharmaceutical Companies

In some cases, a pharmaceutical manufacturer may be liable where a drug caused a patient injuries, but only if the manufacturer failed to warn physicians of the drug's potential side effects or dangers.
