Ophthalmology, ENT and Sensory Care Risk Assessment: Safety, Handover and Control Risks

A worked example of how an eye and ear clinic with day procedures finds, scores and controls the clinical, people, equipment and information risks that could cause avoidable sight or hearing harm.

Updated November 2026 8 hazards assessed Review every 3 months Highest risk: High to Medium
See the Ophthalmology, ENT and Sensory Care course

Executive summary

This assessment shows how an eye and ear clinic with day procedures can find, rate and control the risks that could cause avoidable sight or hearing harm. Eight risks were chosen because they are plausible in everyday outpatient and theatre work, including wrong site errors, medication mistakes, delayed recognition of urgent symptoms, handover and staffing gaps, infection control, consent and records, equipment and system failure, and the care of people with sensory impairment. Each risk is scored before controls and again after existing and added controls. Most risks fall to Medium or Low once added controls are in place, but wrong site and medication risks remain at Medium because the harm is severe. The first actions are a two person check for high risk injections, a structured handover template, a red flag symptom checklist and a calibration register. This is a teaching example, so the scores illustrate method, not a real service, and clinical decisions remain with qualified staff.

Focus area
Ophthalmology, ENT and sensory care
Setting
Outpatient eye and ear clinic with day procedure theatre and community sensory support, in a healthcare setting
Method
Five by five clinical risk register

Scope

This assessment covers outpatient and day procedure services in ophthalmology and ENT, plus support for people with sight or hearing loss, from referral and triage through consent, treatment, follow up and record keeping. It covers risks to patients, staff, equipment, records and the service. It does not give clinical advice. Jurisdiction, regulator, staffing levels and systems are assumptions made for teaching.

Context

The service has consultant ophthalmologists and ENT surgeons, nurses, optometrists, a pharmacist, theatre staff, administrators and a small sensory support team. Patients attend clinics for refraction, hearing tests, injections and minor procedures, with a list of day cases in theatre each week. Records are kept in an electronic clinical system, with paper consent forms and imaging stored on local equipment. Each risk is scored before controls to show its natural level, then again after existing controls and the additional controls proposed here.

Objectives, assets and stakeholders

The objective is to deliver safe, timely and respectful eye and ear care, prevent avoidable harm to sight and hearing, keep consent and records accurate, and keep the trust of patients, families and referring clinicians. The assets in scope are the patients themselves, clinical skills, theatre and clinic equipment, medicines and implants, the electronic clinical record and the sensory support service. Stakeholders include patients and carers, consultants, nurses, optometrists, the pharmacist, administrators, the service manager, referring general practitioners, commissioners and the regulator. Each risk has one owner role, and the clinical director keeps the register current and reports to the governance group each quarter.

H01

Wrong site or wrong procedure error in eye or ear surgery

Safety Before 15 After 8

A procedure is performed on the wrong eye or ear, or the wrong lens or implant is selected, because the site marking, consent record or checklist is incomplete or rushed during a busy list.

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

Causes

Busy lists, similar looking records, skipped time out and verbal instructions given under pressure.

Consequences

Permanent harm to sight or hearing, further surgery, complaint and an external review.

Existing controls

  • Surgical site marking is done before sedation with the patient awake.
  • A written time out checklist is completed before every incision.

Control gaps

Time out is sometimes completed from memory and marking is not checked against the consent form.

Additional controls

  • Prevent: Require the patient to confirm the site aloud against the signed consent form before any sedation.
  • Detect: Audit a sample of lists each month for marking and time out completion.
Likelihood 3 x impact 5 before; 2 x 4 after Owner: Clinical director for surgery Target: Within 30 days Early warning: A list where the time out or site marking record is incomplete or completed after the start.
H02

Medication and dosing errors with eye drops, injections and ototoxic drugs

Safety Before 16 After 6

The wrong drug, strength, eye or dose is given, or a drug with known effects on hearing or the optic nerve is prescribed without review, because labels, orders and allergy records are unclear.

Who or what is affected: Patients, nurses, prescribers and pharmacy staff

Causes

Look alike bottles, verbal orders, rushed clinics and incomplete allergy and kidney function history.

Consequences

Allergic reaction, eye injury, hearing loss, infection after injection and medication incident reporting.

Existing controls

  • Prescriptions are electronic and state the eye or ear to be treated.
  • Pharmacist review is required for high risk injections.

Control gaps

Drops are sometimes prepared at the chair without a second check of the eye and label.

Additional controls

  • Prevent: Use a two person check of drug, eye and dose for intravitreal and other high risk injections.
  • Respond: Reconcile stock and record any near miss within one working day.
Likelihood 4 x impact 4 before; 2 x 3 after Owner: Pharmacy lead Target: Within 45 days Early warning: Near miss reports for wrong eye or wrong strength in any clinic over one month.
H03

Delayed recognition of sudden sight loss, hearing loss or deterioration

Safety Before 15 After 8

A patient with sudden vision loss, severe pain, sudden deafness or dizziness is booked as routine, so urgent treatment or referral is delayed and the damage becomes permanent.

Who or what is affected: Patients, referring clinicians, triage staff and carers

Causes

Triage based on telephone summaries, unclear urgency criteria and high demand on urgent slots.

Consequences

Permanent sight or hearing loss, avoidable admission and complaint.

Existing controls

  • Triage nurse reviews referrals marked urgent within one working day.
  • Patients are given written advice on warning symptoms.

Control gaps

Urgent symptom lists are not on the booking screen and no one checks cancellations for escalation.

Additional controls

  • Prevent: Add a red flag symptom checklist to the booking and referral screen.
  • Detect: Review missed urgent slots each week and report patterns to the clinical lead.
Likelihood 3 x impact 5 before; 2 x 4 after Owner: Clinical lead for urgent access Target: Within 30 days Early warning: Urgent referrals waiting more than the agreed time without a triage decision.
H04

Handover gaps and staffing shortfalls across clinic and theatre

People Before 12 After 6

Staff leave, cover is thin or a handover omits a pending result, a drop regime or a patient's sensory needs, so the next clinician acts on incomplete information.

Who or what is affected: Patients, clinicians, nurses and support staff

Causes

Short notice absence, rota gaps, verbal handovers and no standard template.

Consequences

Missed follow up, repeated tests, delayed care, staff stress and clinical errors.

Existing controls

  • A rota is agreed monthly with named cover.
  • Shift handover is given at the start of each session.

Control gaps

Handover notes are kept in personal files and are not checked at shift end.

Additional controls

  • Prevent: Use a structured handover template that lists pending results, drops and allergies.
  • Respond: Escalate unfilled shifts to the service manager before the session starts.
Likelihood 4 x impact 3 before; 2 x 3 after Owner: Service manager Target: Within 60 days Early warning: Two or more shifts in a month filled at short notice by agency or bank staff.
H05

Infection and exposure control failures in procedures and instrument handling

Safety Before 12 After 6

Instruments are not fully cleaned or sterilized, single use items are reused, or hand hygiene and skin preparation are missed, so infection is passed to patients or staff.

Who or what is affected: Patients, theatre and clinic staff, cleaners and sterile services staff

Causes

Tight turnaround between lists, worn instruments and reliance on individual reminders.

Consequences

Serious infection in the eye or ear, further treatment, closure of a service and staff exposure.

Existing controls

  • Instruments are processed in a validated sterilizer cycle.
  • Hand hygiene audits are reported each quarter.

Control gaps

Cleaning logs are sometimes signed in advance and instrument trays are not checked before release.

Additional controls

  • Prevent: Check each tray against its manifest before release and reject any with damage.
  • Detect: Review sterilizer records and sample tray completeness each month with the infection control lead.
Likelihood 3 x impact 4 before; 2 x 3 after Owner: Infection prevention and control lead Target: Within 30 days Early warning: Any unexplained post procedure infection or a failed sterilizer cycle record.
H06

Consent, privacy and documentation failures in clinical records

Legal and compliance Before 9 After 4

Consent is recorded without a full explanation of risks, or notes and images are shared with the wrong person or stored insecurely, so the patient's choices and privacy are not respected.

Who or what is affected: Patients, families, clinicians and the service

Causes

Pressure to start lists, shared printers and records copied to personal devices.

Consequences

Invalid consent, breach of privacy, complaint and regulatory review.

Existing controls

  • Written consent is taken before each procedure.
  • Records are accessed with individual log ins.

Control gaps

Consent forms are not checked for interpreter or sensory aid needs before treatment.

Additional controls

  • Prevent: Check that consent records the patient's sensory communication needs and a suitable format.
  • Respond: Report and investigate any disclosure or misfiled record within the agreed time.
Likelihood 3 x impact 3 before; 2 x 2 after Owner: Information governance lead Target: Within 60 days Early warning: Records printed or exported outside the clinical system without a logged reason.
H07

Failure of diagnostic equipment and clinical information systems

Technology and data Before 8 After 4

Imaging, audiometry or refraction equipment, or the patient record system, fails or gives wrong readings, so tests are delayed, cancelled or interpreted incorrectly.

Who or what is affected: Patients, clinicians, technicians and administrative staff

Causes

Ageing devices, missed calibration, software updates and network outages.

Consequences

Cancelled clinics, wrong diagnoses, rebooking and loss of records.

Existing controls

  • Equipment is serviced under a maintenance contract.
  • Daily backups of the clinical record are kept.

Control gaps

Calibration dates are recorded on paper and are not reviewed against due dates.

Additional controls

  • Prevent: Keep a calibration register with due dates and block use of any overdue device.
  • Recover: Test a restore of clinical records each quarter and keep a paper downtime form.
Likelihood 2 x impact 4 before; 2 x 2 after Owner: Clinical engineering lead Target: Within 45 days Early warning: Any calibration overdue or repeated system log outs during clinics.
H08

Communication and mobility risks for people with sensory impairment in care

Safety Before 9 After 4

People with poor sight or hearing are not given accessible information, guidance or assistance, so they miss instructions, fall, or feel isolated and cannot raise concerns.

Who or what is affected: Patients with sensory impairment, carers, care staff and visitors

Causes

No standard for large print or hearing loops, staff not trained in guiding people with sight loss, and busy waiting areas.

Consequences

Falls, missed appointments, distress, avoidable harm and complaints.

Existing controls

  • Large print and interpreter support are available on request.
  • Waiting areas have clear signs with high contrast.

Control gaps

Accessible formats are offered on request only and are not recorded in the booking system.

Additional controls

  • Prevent: Record sensory needs on the booking and set the preferred format before the visit.
  • Detect: Ask patients about access at each visit and log any missing aid or support.
Likelihood 3 x impact 3 before; 2 x 2 after Owner: Patient experience lead Target: Within 90 days Early warning: Repeat complaints or missed appointments linked to sensory access in a month.

Rating method and evaluation

Each risk is rated on two five point scales. Likelihood runs from Rare to Almost certain, and impact runs from Insignificant to Catastrophic, with the top of the scale used for permanent loss of sight or hearing. Multiplying the two gives a score from 1 to 25, which falls into 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. The score orders work and is not a measurement. Inherent risk is the score before any controls. Residual risk is the score after existing and additional controls, and it must never be higher than the inherent score. Impact is judged on harm to the patient, including permanent loss of function, the effect on care and the effect on trust, and a clinical risk is never rated down only because it has not happened yet. Anything still High needs senior clinical attention and a dated plan, anything Medium needs routine controls with a named owner, and anything Low is accepted and watched. Staff who do the work should challenge the ratings, and any risk is re-scored when an indicator reaches its threshold or after a significant incident. Specialist clinical and governance review is needed before any rating is used in a real service.

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
Near miss reports for wrong eye, wrong site or wrong strength in any clinic.Escalate to the clinical director when any event is reported, and to the governance group if two occur in one month.
Urgent referrals waiting beyond the agreed time without a triage decision.Escalate to the clinical lead for urgent access when any referral waits beyond the agreed time, and to the service manager if this repeats within a week.
Shifts filled at short notice by agency or bank staff in a month.Escalate to the service manager when more than two shifts are filled at short notice, and to the operations director if cover is still short after a week.
Instrument trays released without a completed manifest check or with a failed sterilizer record.Escalate to the infection prevention and control lead at once, and hold the tray set until it has been checked.
Calibration overdue on any device or repeated system log outs during clinics.Escalate to the clinical engineering lead at once, block use of the device, and report to the clinical director if clinics are cancelled.

Contingency arrangements

If serious harm occurs, such as a wrong site procedure, a severe medication reaction or a sudden loss of sight or hearing, the clinician in charge makes the patient safe, gives urgent treatment and informs the patient and family openly. The clinical director is told at once, the incident is reported in the local system and the open disclosure process is followed. If clinical records or systems fail, the downtime form is used, paper records are secured and the IT lead restores data from the latest tested backup. Clinics that cannot run are rebooked with the referring team, and urgent patients are redirected to the nearest suitable service.

Prioritized action plan

  1. Introduce a two person check of drug, eye and dose for high risk injections, owner pharmacy lead, within 45 days.
  2. Add a red flag symptom checklist to the urgent booking and referral screen, owner clinical lead for urgent access, within 30 days.
  3. Adopt a structured handover template with pending results, drops and allergies, owner service manager, within 60 days.
  4. Confirm site marking and time out before every list, owner clinical director for surgery, within 30 days.
  5. Set up a calibration register with due dates and block overdue devices, owner clinical engineering lead, within 45 days.

Conclusion

Safe eye and ear care depends on a few steady habits: a structured check before every procedure, clear handover, a red flag process for urgent symptoms, calibrated equipment and careful consent. The highest scores sit with wrong site and medication errors, delayed recognition, handover gaps and infection control, and each has actions that lower the residual score. Treat the register as a living record, review it on the stated cycle, and seek qualified clinical and governance advice for any real decision about care, consent, privacy or regulation.

Assumptions and limitations

Assumptions

  • The service is an outpatient and day case unit with no overnight inpatient beds.
  • Clinicians are registered professionals who work within their own scope of practice and local clinical guidelines.
  • Jurisdiction and the governing health regulator are not specified, so legal duties are described in general terms only.
  • Equipment is serviced by a contractor, and records are held in a single electronic clinical system with daily backups.

Limitations

  • The scores are examples for learning and do not describe any real clinic, hospital or patient group.
  • Clinical standards, consent law and privacy rules differ by country and change over time, so specialist review is needed.
  • This is educational content and does not replace a formal site-specific risk assessment or licensed clinical advice.
