Anesthesiology, Pain and Palliative Medicine Risk Assessment: Medication, Equipment and Handover Hazards

A worked example showing how a clinical teaching unit finds, scores and controls risks in anesthesia, pain management and palliative care, from drug errors and equipment failure to handover gaps and delayed escalation.

Updated November 2026 8 hazards assessed Review every 6 months Highest risk: Critical to Medium
See the Anesthesiology, Pain and Palliative Medicine course

Executive summary

This assessment shows how a teaching anesthesia, pain and palliative service can find, rate and control the risks that matter most to patient safety. Eight risks were chosen because they are plausible in theatre, on acute pain rounds and in palliative care. Medication errors, equipment and monitoring failure, and delayed escalation of deterioration carry the highest inherent scores because harm can be serious and quick. Each risk is scored before controls and again after existing and added controls. Most risks fall to Medium or Low once controls are in place, but high-risk medicines and monitoring failure stay at Medium because the potential harm remains severe. The first actions are independent checks for high-risk drugs, a daily equipment check, a structured handover tool and a clear palliative escalation route. The scores illustrate method only and must be reviewed by licensed clinicians.

Five by five likelihood and impact risk register with clinical review

Scope

This assessment covers anesthesia care in theatre and recovery, acute and chronic pain services, and palliative care delivered in hospital and the community. It looks at risks to patients, staff, equipment, records and continuity of care. It does not replace local clinical governance, protocols or the judgment of licensed clinicians. Country, service model and local protocols are assumptions made for teaching.

Context

The example service has consultant anesthetists, anesthesia nurses, pain specialists, palliative care physicians and nurses, pharmacists, and support staff who run theatre lists, an acute pain team and a community palliative team. Patients receive general and regional anesthesia, opioid and adjuvant analgesia, infusions and end of life symptom control. Equipment includes anesthesia workstations, monitors, infusion pumps and a records system. Each hazard is scored before controls to show its natural level, then again after existing and added controls. Scores are for learning and do not describe any real service.

Objectives, assets and stakeholders

The objective is to deliver safe anesthesia, effective pain relief and compassionate palliative care, while protecting patients from avoidable harm, infection and distress, and keeping records accurate and private. The assets in scope are patients and their safety, medicines and controlled drug stocks, anesthesia and monitoring equipment, clinical records and the staff who deliver care. Stakeholders include patients and families, clinicians and nurses, pharmacists, theatre and ward managers, the clinical governance committee, regulators and the service's own funders. Every risk has one owner role. The clinical governance lead keeps the register current and reports to the service board each quarter.

H01

Medication dosing and high-risk drug error

Safety Before 16 After 8

Wrong drug, dose, concentration or rate is given during anesthesia, pain relief or symptom control, particularly with opioids, neuromuscular blockers, local anesthetics and infusions, causing overdose, underdosing or harm.

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

Causes

Time pressure in theatre, look alike drug labels, interruptions and unfamiliar concentrations.

Consequences

Respiratory depression, hypotension, awareness under anesthesia, serious harm and legal action.

Existing controls

  • Controlled drugs are counted and signed at each handover.
  • Infusion pumps have dose limits for common high-risk drugs.

Control gaps

Double checks are skipped during emergencies and pump limits do not cover every drug.

Additional controls

  • Prevent: Require independent double checks for high-risk infusions and labelled prepared syringes before use.
  • Detect: Review infusion pump alarms and dose error reports each week.
Likelihood 4 x impact 4 before; 2 x 4 after Owner: Clinical director of anesthesia Target: Within 30 days Early warning: A controlled drug dose given without an independent check or an unexplained pump alarm.
H02

Anesthesia equipment and monitoring failure

Safety Before 20 After 8

Anesthesia machine, ventilator, gas supply, suction or patient monitor fails or gives false readings during a case, so oxygenation, ventilation or depth of anesthesia is not seen in time.

Who or what is affected: Anesthetized patients, theatre team and recovery staff

Causes

Wear on tubing and sensors, skipped checks, alarms set too low and equipment used beyond its service life.

Consequences

Hypoxia, delayed rescue, cardiac arrest and a serious incident review.

Existing controls

  • Machine checks are run before the first case of the day.
  • Backup oxygen cylinders and a manual ventilation bag are kept in each room.

Control gaps

Checks are recorded on paper and not reviewed, and drill outcomes are not fed back to the team.

Additional controls

  • Prevent: Replace equipment that fails a check and log every fault with a removal date.
  • Respond: Rehearse a failed machine drill with the team each quarter and record the time taken.
Likelihood 4 x impact 5 before; 2 x 4 after Owner: Theatre manager Target: Within 30 days Early warning: Repeated alarms on the same machine or a daily check signed off with a known fault.
H03

Infection transmission and exposure to body fluids

Safety Before 12 After 6

Staff or patients are exposed to blood, body fluids or respiratory droplets through needles, contaminated equipment, poor hand hygiene or unsafe handling of airways, cannulas and drains, causing infection or needle stick injury.

Who or what is affected: Clinical staff, patients, cleaners and visitors

Causes

Busy lists, reusable equipment that is not cleaned correctly, and uncovered sharps during handover.

Consequences

Staff or patient infection, sick leave, legal claims and loss of trust in the service.

Existing controls

  • Single use cannulas and needles are used for each procedure.
  • Sharps bins are placed in each room and staff receive hand hygiene training.

Control gaps

Equipment cleaning is checked only at audit and not at each turnover between cases.

Additional controls

  • Prevent: Use a safer sharps device for each cannula and check hand hygiene at each case.
  • Respond: Follow a written post exposure plan with occupational health contact within the hour.
Likelihood 3 x impact 4 before; 2 x 3 after Owner: Infection prevention and control lead Target: Within 45 days Early warning: Needle stick or splash reports, or cleaning checks missed in a turnover sample.
H04

Undertreated pain and poor pain assessment

Safety Before 12 After 6

Pain is not assessed in a consistent way, so analgesia is delayed, too low or not reviewed, leading to distress, poor recovery, delirium and longer stays, particularly in patients who cannot describe pain.

Who or what is affected: Patients with limited communication, surgical patients and palliative patients

Causes

Reliance on verbal scores, fear of opioids and gaps in staff training on pain tools.

Consequences

Prolonged suffering, chronic pain development, complications and complaints.

Existing controls

  • Pain scores are recorded at each ward round.
  • An acute pain team reviews patients referred for uncontrolled pain.

Control gaps

Tools are not matched to patients who cannot speak, and charts are not audited for quality.

Additional controls

  • Prevent: Use a validated pain tool suited to each patient group and set a review time for each analgesic plan.
  • Detect: Audit a sample of charts each month for pain scores and documented reviews.
Likelihood 4 x impact 3 before; 2 x 3 after Owner: Acute pain service lead Target: Within 60 days Early warning: Pain scores above the agreed threshold with no documented plan change within two hours.
H05

Consent, privacy and documentation lapses

Legal and compliance Before 12 After 4

Consent is not recorded or is not fully informed, patient information is viewed or shared without need, or anesthetic and palliative records are incomplete, leaving care unsafe to follow and patients' rights unprotected.

Who or what is affected: Patients, families, clinicians and information governance staff

Causes

Rushed consent discussions, shared logins and paper records that are copied between teams.

Consequences

Breach of trust, complaints, regulatory investigation and unsafe care from missing information.

Existing controls

  • Consent forms are signed before each procedure.
  • Records are accessible only through named logins.

Control gaps

Access logs are not reviewed and consent is not rechecked when the plan changes.

Additional controls

  • Prevent: Check consent and capacity against a written checklist before the list starts.
  • Detect: Review access logs for records viewed by staff not involved in the patient's care each month.
Likelihood 3 x impact 4 before; 2 x 2 after Owner: Information governance lead Target: Within 60 days Early warning: A consent form missing on the day of procedure or an access log showing unexpected viewing.
H06

Handover and staffing gaps across shifts

People Before 16 After 6

Patients move between theatre, recovery, wards and community teams, and key details such as allergies, infusions and plans are lost or unclear when staff change, or when rotas leave a shift short of competent cover.

Who or what is affected: Patients, nurses, junior doctors and on call teams

Causes

Night and weekend shifts, locum staff, high workload and unstructured handover notes.

Consequences

Missed doses, delayed review, wrong procedures and avoidable harm to patients.

Existing controls

  • Written handover notes are shared at the end of each shift.
  • A rota lists the consultant on call for each day.

Control gaps

Handover notes vary in quality and short staffing is not reported consistently across areas.

Additional controls

  • Prevent: Use a structured handover tool that covers allergies, infusions and escalation plans.
  • Respond: Escalate short staffing to the on call consultant within 30 minutes and record the decision.
Likelihood 4 x impact 4 before; 2 x 3 after Owner: Nurse manager for anesthesia and recovery Target: Within 60 days Early warning: Handover notes missing key items or a shift starting below the agreed staffing minimum.
H07

Delayed escalation of deterioration in palliative care

Safety Before 20 After 9

Symptoms such as breathlessness, agitation, bleeding or uncontrolled pain worsen at home or on the ward, and there is no clear route to a specialist, so patients suffer or die without the planned care.

Who or what is affected: Patients near the end of life, families and community nurses

Causes

Out of hours gaps, unclear roles between teams and families who cannot reach help quickly.

Consequences

Avoidable distress, unplanned admission, poor end of life experience and complaints.

Existing controls

  • A palliative care team reviews inpatients on weekdays.
  • Families are given a contact number for advice.

Control gaps

The advice line is not tested under load and symptom plans are not reviewed after discharge.

Additional controls

  • Prevent: Agree a written symptom plan with each patient and family before discharge.
  • Respond: Provide a 24 hour palliative advice line with a named clinician on call.
Likelihood 4 x impact 5 before; 3 x 3 after Owner: Palliative care lead Target: Within 45 days Early warning: Advice calls not answered within 30 minutes or uncontrolled symptoms lasting over four hours.
H08

Drug and supply shortage or supplier failure

Supplier Before 12 After 4

Essential anesthetic drugs, opioids, blood products or disposable supplies run short because a supplier fails, a product is recalled or a delivery is late, forcing changes to planned care or use of unfamiliar alternatives.

Who or what is affected: Patients, theatre and ward staff and pharmacy teams

Causes

Single source products, delays in supply chains and poor forecasting of demand.

Consequences

Cancelled lists, unsafe substitutions and delayed pain relief.

Existing controls

  • Pharmacy keeps a minimum stock level for key drugs.
  • Two approved suppliers are listed for common items.

Control gaps

Alternatives have not been checked by clinicians and stock forecasts are not reviewed against use.

Additional controls

  • Prevent: Keep a tested alternative list for each critical drug and check it against current stock monthly.
  • Recover: Agree a rapid resupply route and a plan for postponing non urgent lists.
Likelihood 3 x impact 4 before; 2 x 2 after Owner: Pharmacy manager Target: Within 90 days Early warning: Stock of a critical drug below the agreed minimum or a supplier notice of delayed delivery.

Rating method and evaluation

Each risk is rated on two five-point scales. Likelihood runs from Rare to Almost certain, and impact runs from Negligible to Catastrophic, with harm to patients weighted most heavily. 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. Low means accept and monitor. Medium means routine controls with a named owner. High means senior clinical attention and a dated plan. Critical means immediate action, and the activity is paused or changed until the risk is reduced. Inherent risk is the score before any controls. Residual risk is the score after existing and added controls, and it must never be higher than inherent. Ratings are challenged in three ways: frontline clinicians review each score, incident and near miss reports are compared against the register, and any indicator that reaches its threshold triggers a fresh review. Specialist clinical review is needed before any real service uses these scores, and no score is reduced only because an event has not yet happened.

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 6 months, and sooner when an indicator below reaches its threshold.

Early-warning indicators and escalation thresholds
Indicator to watchEscalate when
Controlled drug or high-risk infusion doses given without an independent check.Escalate to the clinical director of anesthesia at once, and to the governance lead if this happens more than once in a month.
Daily equipment checks not signed off before the first list of the day.Escalate to the theatre manager on the same day, and to the clinical director if two lists start unchecked in one week.
Handovers recorded as incomplete or delivered without a structured tool.Escalate to the nurse manager within the shift, and to the governance lead if the rate stays above the agreed threshold for a month.
Palliative patients with uncontrolled symptoms waiting more than four hours for a clinical review.Escalate to the palliative care lead at once, and to the medical director if any patient waits beyond this threshold twice in a month.
Records with missing consent or unexpected access flagged in a monthly sample.Escalate to the information governance lead for review within five working days, and to the governance lead if the rate exceeds the agreed threshold.

Contingency arrangements

If a serious event occurs, such as a drug error, an equipment failure during an anesthetic or an unexpected deterioration in palliative care, the responsible clinician stops the activity, gives immediate clinical care and calls for senior help. The incident is reported, the patient and family are told openly, and records are preserved. Equipment is removed from use and a backup is brought in. Pharmacy and the governance lead are informed the same day, and the clinical team decides how to restart safely.

Prioritized action plan

  1. Introduce independent double checks for high-risk infusions and controlled drugs, owner clinical director of anesthesia, within 30 days.
  2. Add a daily anesthesia machine and monitor check with a signed record, owner theatre manager, within 30 days.
  3. Adopt a structured handover tool for theatre, recovery and ward transfers, owner nurse manager for anesthesia and recovery, within 60 days.
  4. Publish a palliative escalation route with named out of hours contacts, owner palliative care lead, within 45 days.
  5. Review consent and record access rights and set a standard for documentation audits, owner information governance lead, within 90 days.

Conclusion

Safe anesthesia, pain relief and palliative care rest on steady habits: independent checks for high-risk medicines, daily equipment checks, structured handovers, clear escalation and honest documentation. The highest scores sit with medication error, equipment failure and delayed escalation, and each has controls that bring the residual score down. Treat the register as a living record, review it on the stated cycle, and seek specialist clinical advice for any real patient decision or protocol change.
