Orthopedic Surgery and Sports Medicine Risk Assessment: Patient Safety, Infection, Deterioration and Return to Play Controls

A worked example of how an orthopedic surgery and sports medicine service finds, scores and controls risks to patients, from surgical infection and missed deterioration to equipment, consent and return to play decisions.

Updated November 2026 8 hazards assessed Review every 3 months Highest risk: Critical to Medium
See the Orthopedic Surgery and Sports Medicine course

Executive summary

This assessment shows how a teaching orthopedic surgery and sports medicine service can find, rate and control the risks that most affect patient safety. Eight hazards were chosen because they are plausible in theatre, the fracture clinic and the sports medicine team. Missed deterioration after surgery carries the highest inherent score, because a delayed response to compartment syndrome or a blood clot can cause permanent harm. Wrong-site surgery, medication errors and surgical site infection follow closely. Each hazard is scored before controls and again after existing and added controls, and most fall to Medium or Low. The first actions are a structured post-operative observation plan, a recorded time-out before every incision and a written standard for return to play. This is an educational example, so every score illustrates method only. It does not replace a formal site-specific clinical risk assessment, and specialist review is needed for any real service.

Scope

This assessment covers an orthopedic surgery and sports medicine service, from pre-operative assessment and theatre to recovery, clinic follow-up and return to play advice. It looks at risks to patients, staff, equipment, records and trust. It does not give clinical instruction. Jurisdiction, staffing levels, systems and case mix are assumptions made for teaching.

Context

The service runs elective and trauma orthopedic lists in a hospital theatre, a fracture clinic and a sports medicine clinic that treats athletes for injury and rehabilitation. Surgeons, anesthetists, theatre nurses, physiotherapists and a sports physician share care. Implants, imaging, powered instruments and an electronic patient record are used daily. Each hazard is scored before controls to show its natural level, then again after existing controls and the additional controls that should be added.

Objectives, assets and stakeholders

The objective is to deliver safe surgery and sports medicine care, prevent avoidable harm, protect the privacy of patients and keep clinical records accurate. The assets in scope are patients, the theatre and clinic teams, surgical instruments and implants, imaging and monitoring equipment, the electronic patient record and the reputation of the service. Stakeholders include patients and their families, surgeons, anesthetists, nurses, physiotherapists, athletes and their coaches or clubs, hospital governance leads, the infection prevention team, suppliers of implants and equipment, and the regulators that oversee clinical care. Every risk has one owner role, and the clinical governance lead reports the register to the service board each quarter. Patient harm is treated as the top priority in every decision.

H01

Surgical site infection after orthopedic procedures

Safety Before 12 After 6

Bacteria enter the surgical wound during or after an operation, or from implants and dressings, leading to infection that may need further surgery and antibiotics.

Who or what is affected: Patients, theatre staff and the infection prevention team

Causes

Breaks in sterile technique, long operations and patient factors such as smoking or diabetes.

Consequences

Further surgery, prolonged antibiotics, longer hospital stays and lasting disability.

Existing controls

  • Theatre airflow and clothing standards are followed for every list.
  • Skin preparation and prophylactic antibiotics are given on a documented schedule.

Control gaps

Surveillance relies on patients returning to clinic, so late infections are missed.

Additional controls

  • Prevent: Audit theatre hand hygiene and sterile field breaches each month and feed results back to staff.
  • Detect: Track wound infection rates against the local baseline and review every case within 30 days.
Likelihood 3 x impact 4 before; 2 x 3 after Owner: Infection prevention lead Target: Within 45 days Early warning: Surgical site infection or wound discharge reported within 30 days of surgery.
H02

Wrong-site or wrong-procedure surgery

Safety Before 10 After 4

The operation is performed on the wrong limb, side, level or implant because the marked site, consent or patient identity is not checked properly before the incision.

Who or what is affected: Patients, surgeons and the theatre team

Causes

Pressure in busy lists, unclear imaging, interruptions during the time-out and rushed consent.

Consequences

Permanent harm, a second operation, legal claims and loss of trust in the service.

Existing controls

  • Site marking is done by the operating surgeon before sedation.
  • A surgical safety time-out is held before incision.

Control gaps

Time-outs are sometimes completed from memory rather than read aloud from the checklist.

Additional controls

  • Prevent: Mark the operative site on the awake patient and check the marking against the imaging on the list.
  • Detect: Record every time-out and audit a sample of cases against the consent form each month.
Likelihood 2 x impact 5 before; 1 x 4 after Owner: Consultant surgeon lead Target: Within 14 days Early warning: Time-out checks not recorded before an incision.
H03

Anesthetic and medication errors

Safety Before 12 After 6

A wrong drug, dose, route or patient is given during sedation, anesthesia or pain relief, or a known allergy is missed, causing harm or delayed recovery.

Who or what is affected: Patients, anesthetists and recovery nurses

Causes

Look-alike drugs, interruptions and changes to the plan during a case.

Consequences

Respiratory depression, allergic reaction, prolonged recovery or death.

Existing controls

  • Medicines are checked against the prescription before administration.
  • Allergy status is recorded on the patient record before surgery.

Control gaps

Double checks are skipped for routine doses given during emergency lists.

Additional controls

  • Prevent: Use labeled, pre-filled syringes and a single shared drug chart for every theatre list.
  • Respond: Keep an antidote and reversal agent kit checked daily, with a named nurse in charge.
Likelihood 3 x impact 4 before; 2 x 3 after Owner: Consultant anesthetist Target: Within 30 days Early warning: Medication incidents or near misses logged in the theatre safety system each month.
H04

Missed deterioration after surgery

Safety Before 20 After 8

A complication such as compartment syndrome, blood clot, bleeding or infection develops after surgery but is not recognized and escalated in time, so the patient deteriorates.

Who or what is affected: Patients, ward nurses and on-call doctors

Causes

Pain relief masking symptoms, staff unfamiliar with limb checks and night time staffing.

Consequences

Limb loss, organ failure, sepsis and death.

Existing controls

  • Observations are recorded at set intervals after surgery.
  • Patients are reviewed by a doctor within a set time after surgery.

Control gaps

Limb neurovascular checks are not always recorded at the agreed frequency.

Additional controls

  • Prevent: Use a structured post-operative observation plan with agreed escalation thresholds on every ward.
  • Respond: Train staff to call a senior review at once for pain out of proportion, cold or pale limbs and falling urine output.
Likelihood 4 x impact 5 before; 2 x 4 after Owner: Clinical lead for surgical wards Target: Within 30 days Early warning: Patients whose observations cross the early warning threshold without a documented review.
H05

Staffing gaps and unsafe handovers

People Before 12 After 6

Short staffing, inexperienced cover or incomplete handover between theatre, recovery, ward and clinic means that tasks, risks or results are missed.

Who or what is affected: Patients, clinical teams and cover staff

Causes

Sickness, vacancies, reliance on locum cover and busy lists.

Consequences

Delayed treatment, missed results, medication errors and staff burnout.

Existing controls

  • Rotas are planned and reviewed each week by the service manager.
  • Handover is given at shift change using a standard template.

Control gaps

Handover content is not checked, and cover staff rarely receive a formal induction.

Additional controls

  • Prevent: Set minimum competence and supervision rules for cover staff working on orthopedic wards.
  • Recover: Hold a same-day debrief after any shift where a task was missed and update the handover template.
Likelihood 4 x impact 3 before; 2 x 3 after Owner: Service manager Target: Within 60 days Early warning: Shifts running with fewer nurses than the agreed safe minimum.
H06

Equipment, implant and record system failure

Technology and data Before 8 After 3

Powered instruments, imaging, monitors, implants or the electronic patient record fail, are mislabeled or become unavailable during a list, delaying care or causing harm.

Who or what is affected: Patients, theatre staff and the information team

Causes

Ageing equipment, software updates, power or network outages and mislabeled implants.

Consequences

Cancelled surgery, delayed diagnosis, wrong implant use and lost records.

Existing controls

  • Equipment is serviced on a planned schedule.
  • Implants are checked against the order before use.

Control gaps

Downtime forms are not practiced, and implant trace checks are done only at the end of lists.

Additional controls

  • Detect: Log every equipment fault and check implant traceability labels at the start of each list.
  • Recover: Keep a tested downtime procedure with paper forms and restore the record from the latest backup.
Likelihood 2 x impact 4 before; 1 x 3 after Owner: Clinical engineering lead Target: Within 45 days Early warning: Equipment faults or system outages logged during a list.
H07

Consent, privacy and documentation failures

Legal and compliance Before 9 After 4

Consent is taken without full information, the wrong form is used, records are incomplete or altered, or patient data is viewed by staff without a valid clinical reason.

Who or what is affected: Patients, clinicians and the information governance team

Causes

Rushed consent, outdated forms, shared logins and convenience access to records.

Consequences

Legal claims, complaints, loss of trust and regulatory action.

Existing controls

  • Consent forms are signed before the list begins.
  • Access to the patient record requires a personal login.

Control gaps

Access logs are not reviewed, and consent is not rechecked when the planned procedure changes.

Additional controls

  • Prevent: Use a current consent form for each procedure and check it against the booked operation before sedation.
  • Detect: Review record access logs each quarter and follow up any view with no clinical reason.
Likelihood 3 x impact 3 before; 2 x 2 after Owner: Information governance lead Target: Within 60 days Early warning: Consent forms missing or incomplete on the morning of a list.
H08

Premature return to play decisions

Safety Before 12 After 4

An athlete returns to training or competition before tissue healing, strength and movement tests are met, or pressure from a club leads to a decision not supported by clinical findings, raising the risk of re-injury.

Who or what is affected: Athletes, coaches, sports physicians and physiotherapists

Causes

Pressure to play, incomplete testing and short timeframes before competitions.

Consequences

Re-injury, longer absence, chronic pain and loss of athlete trust.

Existing controls

  • Return to play is discussed in clinic before clearance.
  • Physiotherapists record strength and movement test results.

Control gaps

Test thresholds vary between clinicians, and clubs receive decisions without reasons.

Additional controls

  • Prevent: Agree a written return to play standard with objective test thresholds signed off by a sports physician.
  • Respond: Allow the sports physician to withhold clearance without pressure and record the reason.
Likelihood 4 x impact 3 before; 2 x 2 after Owner: Lead sports physician Target: Within 60 days Early warning: Clearance given without a complete set of recorded test results.

Rating method and evaluation

Each hazard is rated on two five-point scales. Likelihood runs from Rare to Almost certain, and impact runs from Minimal to Catastrophic, where Catastrophic means death or permanent harm to a patient. Multiplying the two gives a score from 1 to 25 in one of four bands: Low from 1 to 4, Medium from 5 to 9, High from 10 to 16 and Critical from 17 to 25. Low risks are accepted and watched. Medium risks need routine controls with a named owner. High risks need senior clinical attention and a dated plan. Critical risks pause the affected activity until controls are in place or the service lead formally accepts the risk. Inherent risk is scored before any controls, as if nothing protected the patient. Residual risk is scored after the existing and additional controls. A residual score must never be higher than the inherent score, and a risk that starts at 10 or more must fall below its starting score. Ratings are challenged by the staff who do the work, by a patient safety reviewer who did not write the score, and by a review of recent incidents. Any rating is reopened when a warning indicator reaches its threshold or when an incident occurs. The scores guide the order of work and are not a measurement of real harm.

Likelihood, impact and rating bands

Likelihood

  • 5 Almost certain: Expected to happen in most circumstances.
  • 4 Likely: Will probably happen in many circumstances.
  • 3 Possible: Could happen at some time.
  • 2 Unlikely: Not expected, but it could happen.
  • 1 Rare: Only in exceptional circumstances.

Impact

  • 1 Insignificant: No lasting effect. Handled within routine work.
  • 2 Minor: Small effect that is quickly corrected.
  • 3 Moderate: Noticeable effect that needs managed effort to correct.
  • 4 Major: Serious effect on people, delivery or reputation.
  • 5 Catastrophic: Severe or lasting effect that threatens the whole activity.

Bands (likelihood x impact)

  • Low (1 to 4): Accept and monitor.
  • Medium (5 to 9): Manage with routine controls.
  • High (10 to 16): Senior attention and a treatment plan.
  • Critical (17 to 25): Act first. Do not proceed until reduced.

Monitoring, escalation and review

Review this assessment every 3 months, and sooner when an indicator below reaches its threshold.

Early-warning indicators and escalation thresholds
Indicator to watchEscalate when
Patients whose temperature, pulse or pain scores cross the agreed early warning threshold without a documented review.Escalate to the on-call senior clinician at once, and to the clinical lead if no review is documented within 30 minutes.
Surgical site infections or wound complications reported within 30 days of surgery.Escalate to the infection prevention lead within one working day, and to the service lead if the rate rises above the agreed local level.
Time-out checks not recorded before incision.Escalate to the theatre manager the same day, and pause the list if two are missed in one week.
Equipment or implant faults logged, or instruments found out of date.Escalate to the sterile services manager at once, and remove the item from use until it is checked.
Consent forms missing or record access reviews overdue.Escalate to the information governance lead when any form is missing, and to the medical director if a review is overdue after 30 days.

Contingency arrangements

If a serious event occurs, such as a retained item, a wrong-site procedure, sepsis after surgery or a major equipment failure, the theatre lead pauses the list and secures the patient first. Clinical care is handed to the on-call senior clinician, and the family is told promptly and honestly. The incident is recorded and reported through the local safety system, and the clinical governance lead informs the medical director. Affected equipment is removed from use and replaced from backup stock. The information team restores the electronic record from the latest tested copy if needed. Staff receive support after any serious event.

Prioritized action plan

  1. Introduce a structured post-operative observation plan with escalation thresholds, owner clinical lead for surgical wards, within 30 days.
  2. Confirm that the surgical safety time-out is completed and recorded before every incision, owner theatre manager, within 14 days.
  3. Set a written return to play standard with sports physician sign-off, owner lead sports physician, within 60 days.
  4. Check spare instruments and implants and test a restore of the patient record from backup, owner sterile services manager, within 45 days.
  5. Review consent forms and record access rights each quarter, owner information governance lead, within 90 days.

Conclusion

Safe orthopedic and sports medicine care depends on a few steady habits: a checked time-out before every incision, structured observation after surgery, clear handovers, tested equipment, valid consent and accurate records. The highest scores sit with missed deterioration, wrong-site surgery and infection, and each has actions that lower the residual score. Treat the register as a living record, review it on the stated cycle, and seek specialist clinical and legal advice for any real decision about a patient or service.
