At two on a Tuesday afternoon, theatre three is made up, lit and empty. The nurses are rostered, the trays have been through the steriliser, the anaesthetist is on site, and the surgeon who had that session has taken his list to a hospital eight miles away because he was offered a Thursday morning there and Thursday mornings suit his clinic better.
Nothing has gone wrong. Nobody has been dismissed. The hospital has simply lost a session's theatre income for the rest of the year, because the person who generated it was never its employee.
That is the private hospital business in one room.
The surgeons do not work for you
A private hospital generally does not employ its consultants. It grants them practising privileges: permission to admit and treat patients on its premises, subject to their registration, their indemnity and the hospital's own scrutiny of what they are competent to do. The consultant bills the patient or the insurer for the medical work. The hospital charges separately for the theatre, the bed, the nursing, the drugs and the imaging.
So the people who bring in the revenue are suppliers and sources of demand at the same time, and they can leave. A busy orthopaedic surgeon is worth a great deal to a small hospital, and in most units a handful of consultants account for a disproportionate share of theatre income. They are kept by the things that make a list easy to run: sessions at the time they want them, the nurses they like working with, a scrub team that knows their instruments, and administration that does not lose the paperwork.
Granting privileges is a risk decision rather than a sales one. The hospital carries responsibility for what happens on its premises, so the scrutiny before privileges are granted, and the review of them afterwards, is a governance matter, and the first thing a regulator asks about when something has gone wrong.
The price is largely set by somebody else
The income mix is roughly half insured work, a share of health service contract work, and the rest self-pay.
Insured work comes at tariffs agreed with the insurers, who maintain recognition lists for hospitals and for consultants. A hospital that loses recognition from a major insurer loses the patients attached to it and does not get to argue about the price. Health service contract work comes at a price set by the commissioner. Self-pay, which grows whenever waiting lists lengthen, is the only part you price yourself, and it is increasingly sold as a fixed package rather than an itemised bill.
Then there is the VAT position, which is unusual and permanent. Medical care by a registered health professional in an approved institution is exempt: VAT Act 1994, Schedule 9, Group 7. Exempt is not the same as zero rated. It means no VAT is charged on the treatment, and none of the VAT on the hospital's own costs comes back. Fit out sixty thousand square feet at well over a hundred pounds a foot, buy twelve million pounds of theatre kit and scanners, and the VAT on all of it is part of the cost of the building rather than a reclaim. Every capital decision in this trade is taken on a gross number while the trade next door takes its decisions on a net one.
Theatre utilisation is the number
An empty theatre costs what a full one costs. The nurses are rostered, the room is heated, cleaned and stocked, and the depreciation runs whether or not anybody is on the table.
So the figure the whole business turns on is theatre utilisation: the share of the sessions let that are actually used. A hospital running high utilisation on a moderate case mix beats one half empty on glamorous work, because the fixed cost of a session does not care what happens in it.
That is what makes the monthly decision hard. Sessions are finite. Giving Tuesday afternoon to one consultant is refusing it to another, and either of them could take their work elsewhere. The hospital ends up running its diary as a portfolio: a reliable high-volume surgeon who fills every session, set against a specialist who brings prestige and cancels.
Diagnostics behave better. Imaging pays back more predictably than a theatre, because demand is steadier, the slot is shorter, and the referral does not depend on one person's loyalty.
The year has a shape of its own. Winter pressure and the new year are busy, and August is quiet because the consultants are away and so are the patients. Staffing is heavy and skilled throughout, with a theatre nurse at around £42,000 forming the core of the payroll and ratios that are clinical rather than commercial. Gross margin sits near sixty-two per cent, and the capital is enormous: setting up runs between £12,000,000 and £90,000,000.
The sector is substantial. Something like £12 billion of private acute care in Britain, in the order of ninety thousand people employed, and roughly five hundred and seventy independent hospitals. Those are estimates of the size rather than a published count.
The rating is the business, and it can be taken away
In England a hospital is registered with the Care Quality Commission for each regulated activity it carries out. Scotland and Wales have their own inspectorates.
The Commission's powers are the ones that belong in a business plan. It can impose conditions on a registration, which can be as narrow as a restriction on admitting a particular kind of patient or as wide as stopping admissions altogether. It can suspend a regulated activity. And it publishes a rating, which the insurers read, which referrers read, and which a consultant deciding where to take a list reads.
Around the registration sits the rest of the compliance. Every clinician registered with their own professional regulator. Arrangements for controlled drugs, including a named accountable officer and the registers. Separate rules and duty holders for the imaging. A clinical waste contract, safeguarding policies, disclosure checks on staff, and a data protection fee.
The failure is a chain rather than an event. A serious incident in theatre. An inspection that follows it. Conditions imposed on the registration, which stop part of the work. Insurers suspending recognition while it is resolved. And then the two consultants who between them brought a fifth of the theatre income quietly moving their lists to the hospital ten miles away, which is the part that does not come back when the conditions are lifted.
No other trade has quite this shape. Its capacity is sold to its own suppliers, and those suppliers can walk out with the demand.
Where this shows up in the game
Business Baron runs a private hospital as a diary. The monthly decision is which consultants get which sessions, and there are never enough good sessions to go round. Favour the surgeon who fills every list and you annoy the one who brings the complex work. Favour the specialist and your utilisation falls.
Theatre utilisation is the number on the screen, and it moves because of decisions you took two months earlier. The Care Quality Commission arrives when it arrives. Conditions on a registration stop admissions in the same week they are imposed, and the rating that follows is read by the insurers and by every consultant weighing up where to operate. The ending is the chain above: an incident, an inspection, conditions, a recognition suspended, and the lists that leave.
It is one of the specialist trades, made to sit on top of the full game rather than replace it. The Private Hospital Group page sets out the utilisation model, the exempt VAT position and the setup range.
