Secondary care is specialist care reached by referral rather than by first contact, usually delivered in a hospital. It is the level most medical travel actually competes with, and it is also the level that turns out, on inspection, to have no positive definition in the systems that use the term most.
A residual category
Section 3 of the National Health Service Act 2006 sets out what an integrated care board must arrange: hospital accommodation, other accommodation, medical services other than primary medical services, dental services other than primary dental services, ophthalmic services other than primary ophthalmic services, nursing and ambulance services, maternity and young children’s services, palliative care, prevention, care and after-care, and services for the diagnosis and treatment of illness.[1] The Act never uses the phrase secondary care. What English law describes is everything that is not primary, which makes secondary care a residue rather than a defined level.
The data standards behave the same way. The NHS Data Model and Dictionary defines consultant-led activity as activity in which a consultant retains overall clinical responsibility, noting that the consultant need not be present at each appointment.[5] The dictionary carries no entry for secondary care, and its referral model records the direction, type and destination of a referral without reference to any care-level ladder. Claims that the NHS Data Dictionary defines secondary care do not survive a look at it.
Defined by the referral route
What England does define precisely is the moment of entry. NHS England’s referral-to-treatment guidance starts a consultant-led pathway when a permitted care professional or service refers a patient to a consultant-led service, or to an interface or referral-management service that may onward-refer, with the intent of assessment and if appropriate treatment before care returns to the referrer. The clock starts when the provider receives the referral, and a self-referral starts one only where commissioners and providers have agreed the pathway and a permitted care professional has ratified it.[2] The same guidance describes interface services as sitting between traditional primary and secondary care, which is an admission inside the operational rules that the boundary is occupied rather than sharp.
What crosses borders instead of the term
European Union law governing cross-border care does not use the word secondary. Where a member state wishes to require prior authorisation for care obtained in another member state, Article 8 of Directive 2011/24/EU permits it only for care subject to planning requirements which additionally either involves an overnight hospital stay of at least one night or requires highly specialised and cost-intensive medical infrastructure or equipment, for treatments presenting a particular risk to the patient or the population, or for providers raising serious and specific quality or safety concerns.[3] The operative test for what most systems would call secondary care is therefore a night in a bed, which is a counting rule rather than a clinical category.
Nor does the term appear in the statistics. The Eurostat metadata for health care expenditure records that spending is reported on classifications of function, provider and financing scheme, with functions divided into inpatient, day, outpatient and home-based curative and rehabilitative care and their long-term equivalents, and providers divided into hospitals, residential long-term care facilities, ambulatory providers, retailers of medical goods and providers of preventive care.[6] There are no care tiers in it.
National usage varies
Where the three-tier ladder is used as a description of how services are organised, the content differs by country. An Indian government encyclopaedia entry sets out the Indian arrangement, in which secondary care means district hospitals and block-level community health centres receiving referrals to specialists, with named population catchments at the levels beneath it.[7] WHO’s own glossary uses the term without defining it, referring to counter-referral back to primary care after treatment in secondary or tertiary care, and describing service delivery platforms as primary level, first referral level and second referral level.[8] The referral-level vocabulary is the more exact of the two, and it is the one WHO uses when it needs to be precise.
Relevance to medical travel
Most treatment sought across borders is work a home system would deliver at this level: joint replacement, bariatric surgery, cardiac procedures, fertility treatment. The practical consequence of the term’s vagueness is that there is no agreed category against which to compare a foreign hospital’s activity to a domestic one, and no published series that counts the same thing in both places. Where a comparison is offered, the counting unit is usually the provider’s own.

Sourcing note: three separate searches were made for a published definition of secondary care from a statute, a statistical classification or a national health authority, and none was found. The Arthapedia entry is a signed encyclopaedia article hosted on an Indian government site rather than a statutory instrument, and is cited here as an example of national usage. The claim that no WHO glossary defines secondary care rests on the glossary of the 2020 operational framework, which uses the term without defining it.
