Definition
A hospital is an institution organized for the reception, care, and treatment of sick, injured, infirm, or aged persons. In legal contexts, the term carries layered significance: it describes not merely a physical facility but a recognized legal entity with defined obligations, regulatory status, and liability exposure.
Modern law treats hospitals across several distinct frameworks:
1. As regulated entities. Hospitals operating in the United States are subject to federal and state licensure, accreditation requirements, and — for those receiving Medicare or Medicaid — federal Conditions of Participation administered by the Centers for Medicare & Medicaid Services (CMS). The regulatory definition of "hospital" in this context is precise and determines eligibility for reimbursement, scope of required services, and compliance obligations.
2. As corporate persons. Hospitals are almost universally incorporated as legal entities — either nonprofit charitable corporations, for-profit corporations, or, in some cases, public entities operated by governmental bodies. Their corporate status governs governance structure, tax treatment, liability exposure, and the application of charitable immunity doctrines (now largely abolished or limited).
3. As defendants in tort. The hospital as an institution — distinct from individual physicians — can be held directly liable for negligence in staffing, supervision, credentialing, and systemic failures. This is the domain of institutional malpractice doctrine.
Common Language
Modern common usage (Wiktionary): Wiktionary's primary entry flags "hospital" principally as a surname, which reflects the limits of that source for common English. In ordinary modern usage, a hospital is understood as a building or complex where sick and injured people receive medical care.
Historical common usage (Webster's 1913): "A building in which the sick, injured, or infirm are received and treated; a public or private institution founded for reception and cure, or for the refuge, of persons diseased in body or mind, or disabled, infirm, or dependent." Webster's also notes an obsolete meaning: a place of shelter or entertainment, an inn.
The gap matters for legal research. The ordinary understanding of a hospital as a place — a building — understates what the law is asking when it defines "hospital." Legally, the critical questions are not about walls and beds but about corporate structure, licensure, the scope of duties owed, and whether the institution qualifies as a charitable, governmental, or for-profit entity. Each of those classifications changes the law that applies.
Recognized Forms
/SUBTYPES
Nonprofit/charitable hospital: Incorporated as a tax-exempt charitable organization. Historically shielded by charitable immunity; today subject to community benefit requirements and IRS oversight of tax-exempt status.
For-profit (proprietary) hospital: Operated for shareholder return. Subject to full tort liability; no charitable immunity defense.
Public/governmental hospital: Operated by a government entity. Sovereign immunity principles apply, though most jurisdictions have waived immunity in whole or in part for public hospital negligence.
Teaching hospital: A recognized subtype with additional regulatory obligations and, in malpractice contexts, specific questions about the supervision of residents and the allocation of liability between the hospital and affiliated medical schools.
Critical access hospital: A federal designation for rural hospitals meeting specific criteria under Medicare, conferring different reimbursement rules and regulatory requirements.
Why It Matters in Research
The term "hospital" appears to be self-evident but is one of the more definition-dependent terms in health law research. Several traps await the unwary researcher.
First, regulatory definitions vary by statutory purpose. The definition of "hospital" for Medicare Conditions of Participation purposes is not the same as the definition used in a state tort statute, a certificate-of-need law, or a tax-exemption provision. A facility may qualify as a hospital under one framework and not another. Always identify the governing definition for the legal question at issue.
Second, the charitable/nonprofit status of a hospital has changed dramatically in legal significance. Older sources — including all historical dictionaries represented here — treat the hospital as presumptively a charitable eleemosynary corporation. This was legally significant because charitable immunity once shielded hospitals from most tort liability. Most U.S. jurisdictions have abolished or severely limited charitable immunity for hospitals. Research in pre-1960s sources should be read with this shift in mind.
Third, institutional liability versus physician liability is a live and evolving area. The historical sources reflect a period when hospitals were primarily understood as the place where a physician practiced, not as an independently liable actor. The modern doctrine of corporate negligence — holding hospitals directly liable for credentialing failures and systemic dysfunction — is absent from all historical dictionaries here. Researchers working on malpractice questions must not assume the historical framework governs.
Fourth, the public hospital raises sovereign immunity questions that are entirely absent from the historical record as presented here. Whether a plaintiff can sue a county or state hospital, and under what conditions, requires jurisdiction-specific research.
Fifth, certificate-of-need (CON) laws in states that retain them make "hospital" a gatekeeping term: whether a facility qualifies determines whether it needed prior regulatory approval to operate. This is a pure regulatory definition question.
Historical Dictionary Support
All four historical sources define hospital in nearly identical language: an institution for the reception and care of sick, wounded, infirm, or aged persons, generally incorporated as an eleemosynary or charitable corporation. Black's (both editions) and Bouvier's use verbatim language. Anderson's declines to define independently and simply cross-references the entry on charity.
The consensus reflects the dominant legal reality of the period: hospitals were understood primarily as charitable institutions, incorporated for public benefit, and their legal significance flowed from that charitable character — particularly for purposes of trust law, the law of charitable uses, and the limited tort liability that came with charitable status.
What the historical sources collectively miss is substantial. There is no treatment of licensure or regulatory compliance (a 20th-century development), no discussion of for-profit hospital structures, no concept of institutional malpractice liability, no reference to governmental hospitals and sovereign immunity, and no anticipation of the federal regulatory infrastructure that now largely defines what a hospital is and must do. The Webster's 1913 note that "hospital" once meant a place of general shelter or inn is a useful reminder that the modern specialized meaning is relatively recent.
Jurisdictional Note
State law governs hospital licensure, and definitions vary. Federal law — through Medicare and Medicaid Conditions of Participation — imposes a separate and in some respects more demanding definitional framework for participating institutions. States retaining certificate-of-need laws add another layer of regulatory definition. Charitable immunity for hospitals has been abolished in most but not all jurisdictions; researchers should not assume any uniform rule.
