Value-Based Care and Resource Stewardship
Measuring value: registries and patient-reported outcomes
You cannot improve value you do not measure. The measurement half of value-based care rests on outcomes, and the gold-standard outcomes are those the patient experiences β pain, function and quality of life captured by validated patient-reported outcome measures (PROMs) such as the Oxford Hip and Knee scores, HOOS/KOOS, and the generic PROMIS β tracked alongside the cost and the time taken to deliver them. The full value picture for an orthopaedic episode is therefore outcomes plus cost plus time, measured across the whole care cycle.
National arthroplasty registries are the clearest working example of value measurement in orthopaedics. They capture every joint replacement in a country and report implant survival and revision rates against a common yardstick, which lets the system detect underperforming implants early, drive them out, and standardise high-value pathways:
- Scope
- England, Wales, Northern Ireland, Isle of Man
- How it creates value
- Flags implants and techniques with high revision risk; benchmarking for surgeons and units
- Scope
- Australia β one of the longest-running
- How it creates value
- Annual report of implant survivorship and outlier prostheses; informs implant selection
- Scope
- United States
- How it creates value
- Growing national capture; tracks revision burden and unwarranted variation
- Scope
- Hip and knee arthroplasty
- How it creates value
- Pioneering registry model; links outcomes to patient factors and surgical technique
What registries expose is unwarranted variation β differences in practice and outcome that cannot be explained by patient need. Variation without a clinical reason is, by definition, waste: some patients are getting too much of something and others too little, with no difference in need to justify it. Measuring outcomes across a whole population turns stewardship from an opinion into a discipline, because it lets you show, with data, where the low-value practice actually sits. Using registry and outcome data ethically β protecting patient identity, reporting honestly, and acting on the signal β sits within the broader research-ethics tradition of the Declaration of Helsinki, which insists that evidence used to guide care be generated and reported honestly. [10]
Resource allocation and distributive justice
When a resource is genuinely scarce β a single emergency theatre at night, a limited stock of a specific implant, a finite number of inpatient beds, or the next trauma list β the question stops being about cost-effectiveness and becomes one of distributive justice: how is a fair share decided? Examiners want you to separate the level at which the decision is made from the criteria used to make it.
- Who decides
- Government, insurer, society
- Typical decision
- Fund one implant package over another; establish a national joint registry
- Stewardship lever
- Transparency, cost-effectiveness analysis, democratic mandate
- Who decides
- Hospital, department, network
- Typical decision
- Theatre scheduling, implant formulary, adopting an enhanced-recovery pathway
- Stewardship lever
- Standardised pathways, peer review, audit of variation
- Who decides
- Clinician at the bedside
- Typical decision
- Ordering the right imaging, choosing the right implant, de-prescribing an opioid
- Stewardship lever
- Shared decision-making, appropriate-use criteria
Most of the choices you will defend in a viva are micro-allocation decisions, and the criteria that make them fair are well established. A defensible allocation weighs need (how badly the patient requires the resource), expected benefit (how much good the resource is likely to do), urgency (how soon it must be given to matter), and equity (giving similar patients similar chances). When patients are otherwise indistinguishable on these criteria, a lottery or first-come basis is used as an explicit, transparent tiebreaker β not because it is perfect, but because it is fair in the only remaining sense and is open to scrutiny. Tools such as the quality-adjusted life-year and cost-effectiveness analysis offer one quantitative input into these judgements, but they are contested on equity grounds β they can undervalue the elderly, the disabled and those with shorter baseline life expectancy β so they inform rather than replace the clinician's moral judgement.
What makes an allocation defensible is not only the outcome but the process. Procedural justice demands that the rule be transparent, consistent (the same rule for everyone), relevant to the purpose (allocating by need, not by status), and appealable (a patient can ask for a decision to be reviewed). Patients and colleagues will accept an outcome they disagree with if they can see the rule was applied fairly; they will not accept an outcome β however efficient β that looks arbitrary or self-serving. Say the rule out loud, apply it the same way every time, and you can defend any individual decision.
Systems, checklists and communication: value through reliable design
Much of what we call stewardship is delivered not by individual heroism but by reliable systems β because reliable systems prevent the complications, readmissions and revisions that are the most expensive form of waste. Two ideas anchor this section.
The first is the WHO Surgical Safety Checklist, a short, low-cost tool that teams run through before anaesthesia, before skin incision, and before the patient leaves theatre. [2] Its importance to value is that a virtually costless intervention produces large outcome gains β in a global multi-site study its introduction was associated with a fall in complications and inpatient deaths β exactly the kind of high-value change that improves outcomes while lowering the downstream cost of harm.
11% to 7%complications fell after the WHO checklist (global study, Haynes 2009)The second is the systems model of human error: harm rarely comes from a single reckless individual; it comes from the alignment of latent gaps in several defensive layers, the "Swiss-cheese" model. [4] The implication for stewardship is that value is built by design β checklists, standardised pathways, team training, briefings and debriefings β rather than by exhorting individuals to try harder. A well-designed system wastes less, because it catches errors before they become complications, and complications are where the money and the harm both concentrate.
Reliable communication is part of the same system. Structured handover using ISBAR β Identify, Situation, Background, Assessment, Recommendation β cuts the information loss at shift changes and transfers that drives delay, duplicated investigation and error. Honest communication extends to disclosure when things go wrong: the professional duty of candour (and its equivalents, such as open-disclosure frameworks) requires telling a patient promptly and fully when they have been harmed, which is both an ethical obligation and the precondition for the system learning that prevents the next patient being harmed the same way.

Hook:A clear handover is cheap, fast, and prevents the expensive failures β missed information, duplicated tests, delay β that waste resource and harm patients.
Conflicts of interest and speaking up
Stewardship cannot be separated from conflicts of interest and the duty to speak up. A surgeon who gains financially from using a particular implant, from the volume of surgery performed, or from ownership of an imaging or rehabilitation facility has an interest that may diverge from the patient's, and that interest must be disclosed and managed β not because the surgeon is assumed dishonest, but because transparency is the safeguard that keeps trust intact. The AAOS and royal-college codes place disclosure and management of conflicts squarely within professional conduct. [9]
The same obligation runs towards the conduct of colleagues. If a clinician believes a colleague is delivering care that is consistently low-value, unnecessary, or below standard, the professional duty is to act proportionately β raising the concern through the local pathway first, escalating if patient safety is at risk, and always in the patient's interest rather than from personal grievance. Speaking up about waste and about unsafe practice is the same duty seen from two sides: stewardship is, in the end, accountability for the resource and the trust placed in the profession.
What value-based care is, and why it matters
In its modern form, value is the patient health outcomes achieved per unit of cost over the full cycle of care for a condition. [1] The crucial move in this definition is that it puts outcomes in the numerator and cost in the denominator, so the way to raise value is either to improve outcomes or to lower the total cost of care β and it judges cost over the whole episode, not the sticker price of a single implant. A cheaper prosthesis that fails early and needs revision is low-value, however little it cost to buy; a more expensive implant with measurably better long-term survival and patient-reported function may be high-value.
The cost that matters for value is the total cost of looking after the condition β the implant, the theatre time, the length of stay, the complications, the readmissions, the revision surgery. Cutting one line item in a way that pushes cost elsewhere or harms the patient does not create value, it destroys it. This is why examiners are wary of a candidate who equates "value" with "cheap": that is cost-containment, not value-based care, and the two diverge whenever a saving is bought at the expense of an outcome.
Resource stewardship is the ethical and professional half of the same idea. Orthopaedic care draws on finite shared resources β theatre hours, inpatient beds, blood, implants, imaging, and the working time and attention of the team. A steward holds something in trust for others and is accountable for using it well. The surgeon is a steward of the resources society has invested in health care, and that role is now written into the professional codes of every major system: the GMC tells doctors to make good use of the resources available to them, the AAOS places stewardship within its standards of professional conduct, and equivalent obligations run through AO Foundation, EFORT and royal-college guidance worldwide. [9]
Examiners test this domain because every health system is cost-pressured and because a surgeon who cannot frame a decision in terms of value is unprepared for modern practice β and for the professionalism viva. The candidate who wins marks names the value equation, separates overuse from underuse, distinguishes necessary cost-reduction from value-destroying rationing, and can allocate a scarce resource out loud using a fair and defensible rule.
Outcomes Γ· CostThe value equationThe single idea to carry through the rest of the page: higher valuevia better outcomes or lower total cost is the goal β and waste, the resource spent without benefit or with net harm, is the common enemy of patients and systems alike.
The framework an examiner wants: principles and aims
A viva answer on stewardship is built on a recognised ethical scaffold, not on personal opinion. The scaffold examiners expect is the four-principles approach of Beauchamp and Childress, [7] applied with the population-health aims of the Triple Aim (better care for individuals, better health for populations, and lower per-capita cost β later extended by a fourth aim, clinician wellbeing). The four principles give you a shared moral vocabulary; the aims give you the system-level outcomes to steer towards.
- Core meaning
- Honour the patient's informed, voluntary choices
- What it asks of you at the bedside
- Present options honestly; a patient may decline a low-value test, but cannot demand one you judge harmful
- Core meaning
- Act in the patient's best interest
- What it asks of you at the bedside
- Provide evidence-indicated care even when it costs the system more
- Core meaning
- Avoid causing harm
- What it asks of you at the bedside
- Do not expose patients to the risks of unnecessary imaging, injections or surgery
- Core meaning
- Distribute benefits and burdens fairly
- What it asks of you at the bedside
- Allocate theatre time, implants and beds on need and expected benefit, not on influence or convenience
Justice is the spine of stewardship β it is the principle that asks how a fair share of a finite resource is determined β but it never acts alone. Autonomy stops you withholding information to steer a patient towards a cheaper option. Beneficence and non-maleficence stop you substituting cost for quality. The four principles are designed to be balanced and specified against the case in front of you, and a strong answer names which principles are in tension before it resolves them.
A common viva error is to treat "justice" as a licence to ration. It is not. Justice must be balanced against beneficence and non-maleficence β the duty to the patient in front of you does not evaporate because resources are scarce. The defensible position is to deliver the right care to each patient and to attack the low-value care that wastes resource without benefit; you do not balance the budget by denying a patient treatment they genuinely need. When principles conflict, say so explicitly, then justify how you weighted them.
Appropriate use and Choosing Wisely
The part of waste a surgeon controls most directly is overuse β care that offers no benefit or net harm to the patient. Overuse is one of the recognised categories of health-system waste, alongside failures of care delivery and coordination, administrative complexity, pricing failures and fraud. [3] The bedside instruments for cutting overuse are appropriate-use criteria and the Choosing Wisely movement.
Appropriate-use criteria match an intervention to a specific clinical situation, so that a test or operation is recommended when the expected benefit justifies the risk and cost, and discouraged when it does not. Choosing Wisely, launched by the ABIM Foundation, asks each specialty to publish a short list of tests and treatments that clinicians and patients should question because the evidence shows no benefit or net harm. [8] The orthopaedic and musculoskeletal lists are explicitly clinician-owned β they are stewardship delivered by the profession rather than imposed on it β and they target the exact overuse that destroys value.
Representative Choosing Wisely recommendations for orthopaedic practice include avoiding an intra-articular corticosteroid injection in the months immediately before an elective arthroplasty (because of the infection risk), avoiding advanced imaging for uncomplicated acute low back pain before assessment for red flags, limiting postoperative antibiotic prophylaxis to the shortest evidence-based course, and prescribing opioids for musculoskeletal pain only with a risk-mitigation plan. [8] Each removes a measured harm from the patient and a measured cost from the system at the same time β the definition of high-value change.
The mirror image of overuse is underuse β failing to provide care that would clearly benefit the patient. Underuse is just as much a value failure as overuse: a displaced femoral neck fracture in a fit patient that is left in pain rather than operated, or a high-energy plateau fracture managed on plain films alone without the CT that changes the plan, sacrifices outcomes and often costs more in the long run through avoidable complications. Stewardship cuts both ways; the surgeon who "conserves resource" by under-treating is not a steward, just a different kind of poor-value provider.
Stewardship is never a licence to deny care a patient needs. Withholding or delaying an evidence-indicated investigation or operation purely to save money, or to hit a throughput target, is a breach of the duty of care and falls below the standard the law requires. The defensible position is to deliver the right care, to the right patient, at the right time β and to strip out only the low-value care that harms patients and wastes resource. If you are pressured to ration necessary care, document the clinical reasoning, escalate to the person accountable for the resource decision, and act in the patient's interest.
Exam and revision
Everything below condenses the topic for revision and viva practice β the points that win marks, the memory hooks, three worked vivas, and a one-screen cheat sheet.
- Value = outcomes per unit of cost over the full care cycle β raise it by improving outcomes or lowering total cost; it is not the same as "cheap". [1]
- Stewardship is a professional duty, written into the GMC, AAOS and AO codes β it is not optional or a favour to the budget. [9]
- Waste has named categories; roughly thirty percent of spend is waste, and overtreatment is the part surgeons control directly via Choosing Wisely and appropriate-use. [3,8]
- Underuse is also a value failure β conserving resource by under-treating sacrifices outcomes and often costs more later.
- Justice governs allocation, but it is balanced against beneficence and non-maleficence β never ration necessary care. [7]
- Montgomery makes appropriate-use a shared decision; Bolam/Bolitho set the floor of care below which cost-cutting cannot go. [5,6]
- Reliable systems create value β the WHO checklist cut complications from about eleven to seven percent; design beats exhortation. [2,4]
- Say the allocation rule out loud β need, expected benefit, urgency, equity β and apply it consistently.

Viva practice
Practise clinical reasoning and management decisions out loud
βA fit sixty-five-year-old is listed for an elective total hip replacement. Your hospital's management asks you to use a lower-cost implant whose ten-year revision rate in the national registry is measurably worse than the prosthesis you usually use. How do you respond?β
βA forty-year-old with two weeks of non-specific lower back pain and no red flags requests an MRI, which they have read about online and believe is needed to rule out serious disease. How do you counsel them, and what is the ethical basis for your approach?β
βYou are the on-call consultant. A multiple-casualty incident has produced two patients who both need the single available emergency theatre within the next hour: a young adult with a mangled limb from a severe open fracture, and an older patient with an unstable pelvic ring injury and haemodynamic compromise. Walk me through how you decide who goes first, and the ethical basis for your decision.β
The core idea
- Value = patient health outcomes achieved per unit of cost over the full care cycle (Porter)
- Raise value by improving outcomes OR lowering total cost β not by buying the cheapest item
- Waste is the common enemy; roughly thirty percent of health spend is waste, and overtreatment is the part surgeons control
- Underuse is also a value failure β stewardship cuts both ways
The ethical scaffold
- Four principles (Beauchamp and Childress): autonomy, beneficence, non-maleficence, justice
- Justice governs fair allocation, but is balanced against beneficence and non-maleficence β never ration necessary care
- Stewardship is a professional duty (GMC, AAOS, AO codes), not optional
- Triple Aim: better care, better health, lower per-capita cost (plus clinician wellbeing)
Tools and law
- Appropriate-use criteria and Choosing Wisely target low-value care at the bedside
- Registries (NJR, AOANJRR, AJRR, SHAR/SKAR) and PROMs measure outcomes and expose unwarranted variation
- Allocation by need, expected benefit, urgency, equity β with a transparent, consistent, appealable process
- Montgomery: shared decision-making, material risks and reasonable alternatives
- Bolam and Bolitho: standard of care is a responsible body of opinion that withstands logical scrutiny
Systems and professionalism
- WHO Surgical Safety Checklist cut complications from about eleven to seven percent (Haynes 2009)
- Swiss-cheese model: build defences in depth; value by design, not exhortation
- ISBAR handover and duty of candour reduce error, waste and harm
- Disclose and manage conflicts of interest; speak up proportionately about low-value or unsafe practice
Evidence
What is value in health care?
- Defines value as the patient health outcomes achieved per dollar spent over the full cycle of care for a medical condition
- Argues that the unit of analysis should be the patient's condition over the full care cycle, not an individual service or the price of a device
- Warns that cost-reduction which sacrifices outcomes destroys value, and that containing costs without regard to outcomes is a strategic error
A surgical safety checklist to reduce morbidity and mortality in a global population
- Across eight hospitals in high-, middle- and low-income settings, introduction of the WHO Surgical Safety Checklist was associated with a fall in major complications from 11.0% to 7.0% and in inpatient death from 1.5% to 0.8%
- Surgical-site infection and unplanned return to theatre also fell after checklist introduction
Eliminating waste in US health care
- Estimated that roughly 30% of United States health-care spending is waste, distributed across six categories: failures of care delivery, failures of care coordination, overtreatment, administrative complexity, pricing failures, and fraud and abuse
- Identified overtreatment as the category most amenable to direct clinician action
Human error: models and management
- The Swiss-cheese model: harm occurs when latent gaps in multiple defensive layers momentarily align
- Contrasts the person approach (blame individuals) with the system approach (engineer safer defences), and argues for building systems in which error is inevitable but harm is preventable
Montgomery v Lanarkshire Health Board [2015] UKSC 11
- Replaced the Bolam test for the disclosure of risk with a patient-centred materiality test
- A doctor must take reasonable steps to warn of any material risk and to explain all reasonable alternatives, including no treatment
- A risk is material when a reasonable person in the patient's position would be likely to attach significance to it, or the doctor is or should reasonably be aware the particular patient would
Bolam v Friern Hospital Management Committee (1957); Bolitho v City and Hackney Health Authority (1997)
- Bolam: a practitioner is not negligent if acting in accordance with a practice accepted as proper by a responsible body of relevant medical opinion
- Bolitho: that body of opinion must also be capable of withstanding logical analysis β the court may reject a practice that is not reasonable or responsible
Principles of Biomedical Ethics
- Sets out the four-principles approach β respect for autonomy, beneficence, non-maleficence and justice β as a shared moral language for clinical ethics
- Provides methods of specification and balanced judgement for resolving conflicts between principles in concrete cases
Choosing Wisely β clinician-led campaigns against low-value care
- Specialty societies publish lists of tests and treatments clinicians and patients should question, where evidence shows no benefit or net harm
- Orthopaedic and musculoskeletal entries include avoiding corticosteroid injection shortly before elective arthroplasty, avoiding advanced imaging for uncomplicated acute low back pain before red-flag assessment, limiting postoperative antibiotic prophylaxis to the shortest evidence-based course, and prescribing opioids only with a risk-mitigation plan
Professional codes on resource stewardship and conflicts of interest
- Good Medical Practice requires doctors to make good use of the resources available to them and to protect patients from financial or commercial exploitation
- AAOS Standards of Professionalism and Code of Medical Ethics and Professionalism set out duties around conflicts of interest, disclosure and the responsible use of health-care resources
- Equivalent obligations run through AO Foundation professional conduct standards and royal-college codes worldwide
