Tracking Clinical Deterioration

Before initiating deterioration tracking, confirm:

1. Which early warning scoring system does the institution use — NEWS2, MEWS, or a proprietary system? (Default: NEWS2)
2. What is the vital sign monitoring frequency — Q4h, Q2h, Q1h, continuous? (Default: Per acuity level and current orders)
3. What are the institution's escalation thresholds and corresponding actions? (Default: See NEWS2 escalation protocol below)
4. Does the patient have baseline abnormalities that affect scoring — chronic hypoxia (COPD on home O2), baseline tachycardia (autonomic dysfunction), chronic hypotension? (Default: Document baselines to prevent alarm fatigue)
5. Is there a rapid response team (RRT) or medical emergency team (MET) available? (Default: 24/7 coverage required)
6. What is the patient's code status — does it affect the escalation pathway? (Default: Full code escalation; modified for DNR/CMO)
7. Has the patient had any sentinel events in the past 24 hours — falls, medication errors, procedures, new symptom onset? (Default: Review event log)

Documents to Request

• Vital sign flowsheet with 24-48 hour trends
• Current NEWS2 or MEWS scores (if auto-calculated by EMR)
• Medication administration record (sedatives, antihypertensives, opioids that affect vitals)
• Recent lab results (lactate, WBC, creatinine, troponin)
• Active problem list with baseline physiologic parameters
• Code status documentation
• Prior rapid response or code blue records (if applicable)

Step 1: Calculate the NEWS2 Score

The National Early Warning Score 2 uses seven physiologic parameters:

SpO2 Scale 2 is used for patients with hypercapnic respiratory failure (e.g., COPD with target SpO2 88-92%).

Total score range: 0-20

Step 2: Apply Escalation Protocols Based on Score

Rapid Response Team (RRT) activation criteria (in addition to NEWS2 ≥ 7):

• Acute change in mental status (new confusion, lethargy, agitation)
• Respiratory distress not responsive to current oxygen delivery
• New-onset chest pain with hemodynamic changes
• Systolic BP < 80 mmHg despite fluid resuscitation
• Urine output < 0.5 mL/kg/hr for > 4 hours
• Staff or family "worried" about patient (gut instinct criterion)

Step 3: Document Deterioration Events

When clinical deterioration is identified, document the following:

CLINICAL DETERIORATION NOTE

Date/Time of recognition: [Timestamp]
NEWS2 Score: [Score] (prior score [X] at [time] — change of [+/-Y])
Triggering parameters: [List specific abnormal vitals]

Assessment:
- Clinical presentation: [Describe current status]
- Likely etiology: [Differential for deterioration — sepsis, PE, ACS, 
  hemorrhage, respiratory failure, medication effect]
- Interventions initiated: [Specific actions taken]

Escalation:
- RRT activated: Yes/No — if no, document rationale
- ICU consulted: Yes/No
- Attending notified: Yes/No — time and method
- Family notified: Yes/No (per patient preference)

Orders placed:
- [List new orders — labs, imaging, medications, monitoring changes]

Plan:
- Continue monitoring at [frequency]
- Reassess in [timeframe]
- Escalation threshold for next action: [Specific parameter]

Step 4: Prevent Failure to Rescue

Implement these proactive monitoring strategies:

High-risk populations requiring enhanced monitoring:

• Post-procedure patients (first 24 hours)
• Patients on opioid PCA or IV opioids (respiratory depression risk)
• Patients with new or escalating oxygen requirements
• Patients transferred from ICU within 48 hours ("ICU bounce-back" risk)
• Patients receiving blood products (transfusion reactions)
• Patients with sepsis or suspected infection on antibiotics < 48 hours
• Patients with active GI bleeding

Afferent limb optimization (detection):

• Ensure vital signs are taken at ordered frequency — audit compliance
• Use continuous pulse oximetry for high-risk patients
• Implement capnography monitoring for patients on opioid infusions
• Encourage nursing to escalate "gut feeling" concerns without objective threshold

Efferent limb optimization (response):

• RRT must arrive at bedside within 5 minutes of activation
• Pre-built order sets for common deterioration scenarios (sepsis bundle, STEMI protocol, stroke code)
• ICU bed availability confirmed within 30 minutes of transfer decision

Checkpoint B: Post-Draft Alignment (Mandatory)

After any deterioration event or monitoring review:

1. Is the NEWS2 score accurately calculated and documented?
2. Was the escalation protocol followed for the score level?
3. Are new orders and monitoring frequency changes in place?
4. Has the attending been notified of all Medium and High risk scores?
5. Is there a reassessment plan with specific timeline and parameters?

Quality Audit

• NEWS2 score is calculated at every vital sign assessment
• Baseline abnormalities are documented to contextualize scoring
• Escalation protocol matches the score level
• RRT activation criteria are posted and accessible to nursing staff
• Deterioration events are documented with the structured note template
• Time from recognition to physician assessment is within protocol limits
• ICU transfer decision time is documented
• Code status is confirmed before escalation actions
• Medication effects on vitals are considered (beta-blockers, opioids, sedatives)
• Post-deterioration debrief is conducted for RRT activations
• Score trending is documented (not just current score, but trajectory)
• Family/patient notification occurs per preference documentation
• High-risk populations have enhanced monitoring orders in place

Guidelines

• Trending is more important than absolute values — a NEWS2 score of 4 that was 1 yesterday is more concerning than a stable 4
• Never dismiss single-parameter scores of 3 — these are clinically significant even if the total score is low
• Baseline documentation prevents alarm fatigue — a COPD patient with chronic SpO2 of 90% should not trigger the same response as a previously healthy patient
• Respiratory rate is the most sensitive early indicator of deterioration and the most commonly inaccurately measured vital sign — encourage actual counting for 60 seconds
• Family and nursing concern ("something is wrong") should be treated as a valid escalation trigger per The Joint Commission Condition H standards
• Document the clinical reasoning for NOT escalating when a score would otherwise trigger action (e.g., "NEWS2 = 5 due to chronic baseline tachycardia; patient at clinical baseline per nursing assessment")
• After every RRT activation, conduct a brief debrief: Was escalation timely? Were there earlier signs that were missed?
• Patients transferred from ICU should have enhanced monitoring (Q2h vitals minimum) for the first 24-48 hours on the floor
