Patient Safety & Error 06

Patient safety studies how healthcare can reduce preventable harm. Errors rarely arise from one isolated cause. Workload, interruptions, confusing interfaces, staffing, equipment, communication and organizational culture can combine with human limitations.

Systems thinking asks why defences failed. If two medicines have nearly identical packaging, repeated selection errors may persist despite telling staff to “be careful.” Redesigning storage or labelling can create a stronger defence.

Systems analysis does not eliminate individual accountability. Deliberate reckless behaviour differs from a reasonable human error within a poorly designed process.

A mature safety culture can hold people accountable while still learning from the conditions that made an error possible.

Human attention and memory are limited. Fatigue, multitasking, noise and time pressure increase the chance of omission and misinterpretation. Safe systems should not assume perfect concentration for every task.

Cognitive biases also affect diagnosis. Anchoring occurs when early information receives excessive weight; premature closure occurs when alternatives stop being considered too soon; confirmation bias favours evidence supporting an existing belief.

Checklists, deliberate diagnostic pauses, second opinions and structured handovers can reduce some vulnerabilities, but tools work only when used thoughtfully.

Personal wellbeing becomes a safety issue when impairment affects performance. Seeking help for fatigue, illness or distress can be a professional action rather than a failure of resilience.

A near miss is an event that could have caused harm but did not, sometimes because of chance or a final safety barrier. Near misses are valuable because they reveal hazards without requiring a patient to be injured first.

When an incident occurs, immediate clinical care comes first. Then preserve an accurate record and use the institution's reporting process. Incident reports are for organizational learning and should not replace the clinical record.

Reporting systems can identify recurring patterns across many small events. A single omitted dose may appear isolated; dozens of similar reports may reveal a workflow defect.

Fear-based cultures suppress reporting. A learning culture encourages appropriate reporting while maintaining proportionate accountability for genuinely unsafe conduct.

Medication errors can occur during prescribing, transcription, dispensing, administration and monitoring. High-risk medicines, look-alike names, decimal points, allergies, renal function and drug interactions require particular attention.

Before prescribing or administering, verify patient identity, medicine, dose, route, timing, indication and relevant contraindications according to role and policy. Medication reconciliation at transitions of care can identify omissions and duplications.

A dose that is mathematically correct can still be clinically wrong if the indication, organ function or formulation has been misunderstood. Calculation and clinical reasoning must therefore be combined.

When uncertain, stop and verify. Time pressure is not a justification for guessing with a high-risk medicine.

When care has gone wrong, the patient needs accurate information about what is known, the immediate consequences and what is being done next. Open disclosure should be timely, compassionate and coordinated with appropriate senior staff and institutional procedures.

An apology can express regret and respect without inventing facts before investigation is complete. Avoid speculation about blame. Distinguish what is established from what remains under review.

Concealment creates additional harm: treatment may be delayed, records become unreliable and trust is damaged. Falsifying a record is especially serious because it corrupts both care and later investigation.

Learning should lead to concrete prevention where possible. “Be more careful” is weaker than redesigning a vulnerable process.

Infection prevention is a professional and patient-safety duty. Hand hygiene, appropriate personal protective equipment, safe sharps practice and aseptic technique interrupt routes of transmission.

The correct precaution depends on the clinical situation and institutional guidance. Protective equipment should not become a substitute for hand hygiene or correct technique.

Students must not conceal an exposure or sharps injury. Prompt reporting enables risk assessment, testing and prophylactic measures where indicated.

Professional behaviour also includes protecting colleagues and patients by not working unsafely when an infectious illness or exposure requires occupational-health advice.
