Clinical Reasoning Cycle (CRC) – Stages 5-8, Errors, Escalation, Case Study, and Learning points

Stage 1: Notice the person's current situation

  • Consider salient features about the person and their situation and anticipate emergent issues or concerns.

Stage 2: Collect cues/information

  • Review current information (e.g. handover reports, patient history, medical records, results of investigations and nursing/medical assessments previously undertaken).

  • When reviewing the person’s background, consider characteristics such as gender identity, sex assigned at birth, neurodivergence, ethnicity, etc.

  • Gather new information (e.g. subjective and objective assessment data and concerns of the person and their family and/or significant others as appropriate).

  • Recall knowledge (e.g. physiological, pharmacological, cultural, spiritual, environmental, ethical and legal factors).

Stage 3: Process information

  • Analyse cues and determine whether the person’s signs and symptoms are within expected ranges.

  • Discriminate: Differentiate relevant from irrelevant information; recognise inconsistencies; refine information to what is most important; recognise gaps in cues collected.

  • Relate: Discover new relationships or patterns; cluster cues together to identify relationships between them.

  • Infer: Form opinions by interpreting subjective and objective cues; consider alternatives and consequences.

  • Recognise the potential for one’s biases and preconceptions to influence opinions and thought processes.

  • Match current situation to previous situations.

  • Predict an outcome.

Stage 4: Synthesize facts and inferences to formulate a nursing diagnosis

  • Example: "Risk of impaired ventilation (concern) related to acute upper airway obstruction (related etiology) evidenced by swollen tongue and altered appearance (supporting evidence/cues)." extNursingdiagnosisexample:Riskofimpairedventilationrelatedtoacuteupperairwayobstructionevidencedbyswollentongueandalteredappearanceext{Nursing diagnosis example: Risk of impaired ventilation related to acute upper airway obstruction evidenced by swollen tongue and altered appearance}

Stage 5: Describe desired outcomes and engage in shared decision making

  • Describe what you want to happen, a desired outcome and a time frame.

  • Engage in shared decision making with the person, their family and/or significant others as appropriate.

Stage 6: Prioritize actions

  • Prioritise action/s based on the different alternatives available.

  • This may include consultation with other members of the healthcare team and collaboration with the person, their family and/or significant others.

Stage 7: Escalating concerns (communication strategies)

  • Escalating concerns using graded assertiveness:

    • CUS: I’m Concerned, I’m Uncomfortable, this is not Safe.

    • PACE: Probe, Alert, Challenge, Emergency.

  • Example escalation framework (Summary):

    • Probe: Recognise and articulate the concern (e.g., signs of deterioration such as pain, hypotension, tachycardia, tachypnoea, oligoanuria).

    • Alert: Indicate you believe the patient may be sepsis and requires full assessment and escalation.

    • Challenge: Assert that the current plan is insufficient and that escalation is needed (e.g., involve consultant).

    • Emergency: If deterioration continues, call rapid response and contact the consultant.

    • Practical dialogue snapshot (from the scenario):

    • Probe: Nurse notes severe pain, hypotension, tachycardia, tachypnoea, mother’s concern.

    • Alert: Nurse flags possible sepsis and need for bloods and consultant evaluation; senior staff resists.

    • Challenge: Nurse asserts deterioration, red flag status, and necessity of consultant involvement.

    • Emergency: Nurse initiates rapid response and calls consultant (as needed).

Stage 8: Evaluate progress and outcomes

  • Evaluate progress and the effectiveness of actions.

  • Consider whether the person’s situation has improved from both a clinical perspective and the person’s perspective.

  • Evaluate Outcomes (after initiation of a rapid response and appropriate medical care):

    • extBP,HR,andRRwithinnormalrangesext{BP, HR, and RR within normal ranges}

    • ext{Urine output > 30}\,\text{mL/hr}

    • extPain3/10ext{Pain ≤ 3/10}

    • extAbletowalktothebathroomindependentlyext{Able to walk to the bathroom independently}

  • Reflection: Contemplate what you have learnt, what you could have done differently, and how this informs future practice.

The Clinical Reasoning Cycle: Errors, biases, and safeguarding practice

Common clinical reasoning errors and biases

  • Anchoring: Locking onto salient features early and failing to adjust with new information.

  • Ascertainment bias: Thinking shaped by prior assumptions/preconceptions (e.g., ageism, stigmatism, stereotyping).

  • Diagnostic momentum: Once a label is attached, it tends to persist and other possibilities are excluded.

  • Overconfidence bias: Belief that we know more than we do; acting on incomplete information or hunches.

  • Premature closure: Accepting a nursing diagnosis without sufficient evidence.

Skipping steps (risks)

  • Skipping steps undermines the CRC; reflect, evaluate, and ensure the cycle is followed from notice through to synthesis and evaluation.

Case study: Lewis (2 days post-surgery)

  • Presentation: Acute upper abdominal pain (possible constipation), diaphoresis, nausea, tachypnoea, tachycardia, hypotension, oliguria.

  • Working hypothesis: Signs consistent with hypovolaemic and/or septic shock.

  • Probable actions to take:

    • Reassess vitals and pain; obtain urgent investigations (bloods, cultures, imaging as indicated).

    • Administer fluids as indicated and reassess response.

    • Notify/consult surgery and pediatric specialists; prepare for rapid response if deterioration continues.

    • Monitor urine output, fluid balance, and hemodynamics closely; ensure airway and breathing support as needed.

    • Review analgesia and NSAID/narcotic use; consider opioid-sparing strategies if hemodynamically unstable.

Escalating concerns in practice: detailed example (Lewis case)

  • Probe: Identify severe pain, hypotension, tachycardia, tachypnoea, and oliguric status; acknowledge family concern.

  • Alert: Propose sepsis workup and consultant involvement; resistance from senior staff (perceived constipation).

  • Challenge: State deteriorating condition, red zone on the Between the Flags chart, need for consultant input.

  • Emergency: Initiate rapid response and contact consultant immediately if condition worsens or does not improve.

Evaluation of outcomes in the Lewis scenario

  • Key cues for improvement after rapid response and medical care: stabilization of vital signs, improved urine output, tolerance of fluids, reduced pain, and functional mobility improvements.

Closing thought

  • "UNLESS someone like you cares a whole awful lot, nothing is going to get better. It’s not." — The Lorax (motivational reminder of responsibility in care)

The Clinical Reasoning Cycle (CRC) is an eight-stage process for nurses to ensure patient safety and effective care:

  1. Notice: Identify the patient's current situation and potential issues.

  2. Collect Cues: Gather information from existing records, new assessments, and relevant knowledge (e.g., physiological, pharmacological, cultural).

  3. Process Information: Analyze cues, differentiate relevant from irrelevant, cluster information, infer conclusions, recognize biases, match situations, and predict outcomes.

  4. Synthesize Diagnosis: Formulate a nursing diagnosis, e.g., Risk of impaired ventilation related to acute upper airway obstruction evidenced by swollen tongue and altered appearance

  5. Desired Outcomes: Describe desired outcomes and engage in shared decision-making.

  6. Prioritize Actions: Select and prioritize actions, often in consultation with the healthcare team.

  7. Escalate Concerns: Communicate concerns using graded assertiveness (CUS: Concerned, Uncomfortable, Safe; PACE: Probe, Alert, Challenge, Emergency).

    • Example escalation: Probe (recognize deterioration), Alert (suggest condition like sepsis), Challenge (assert need for consultant), Emergency (initiate rapid response).

  8. Evaluate & Reflect: Evaluate progress and outcomes (e.g., \text{BP, HR, and RR within normal ranges; Urine output > 30}\,\text{mL/hr; Pain \le 3/10}); reflect on learning.

Common Clinical Reasoning Errors:
  • Anchoring: Sticking to initial features without adjusting to new information.

  • Ascertainment bias: Opinions shaped by prior assumptions (e.g., ageism).

  • Diagnostic momentum: A diagnosis persists, excluding other possibilities.

  • Overconfidence bias: Acting on incomplete information.

  • Premature closure: Accepting a diagnosis without enough evidence.

Case Study: Lewis (2 days post-surgery)
  • Presentation: Acute upper abdominal pain, diaphoresis, nausea, tachypnoea, tachycardia, hypotension, oliguria.

  • Hypothesis: Hypovolaemic and/or septic shock.

  • Actions: Reassess vitals, obtain investigations, administer fluids, notify specialists, monitor vitals, review analgesia.

  • Escalation Example: Nurse probes severe pain, alerts to possible sepsis, challenges senior staff resistance, and initiates rapid response if needed.

Key Takeaways:
  • The CRC is crucial for patient safety, preventing an estimated 50−80%50−80% of adverse events.

  • Nurses' clinical reasoning skills directly impact patient outcomes.
