✅ PICO Analysis

Type of Study:

Narrative clinical review (expert synthesis of incidence, diagnosis, management, and prevention of NHAP)

---

P – Population

• Setting:Nursing home residents in the United States and Canada
• Population Characteristics:
  • Older adults in long-term care
  • Frail, often with dementia, dysphagia, functional impairment
  • High rates of aspiration risk and comorbidities
  • Annual NHAP incidence ranges from 0.3 to 2.5 episodes per 1000 resident-days

---

I – Intervention

While this is not a comparative study, the review explores diagnostic, therapeutic, and preventive interventions, including:

1. Diagnosis recommendations (from guidelines):
   • WBC count, pulse oximetry (if RR >25), chest radiography
   • Respiratory specimen culture (when feasible)
   • Avoid routine blood cultures
2. Treatment considerations:
   • Route: oral vs parenteral (IM injection commonly used)
   • Empirical therapy advised due to limited diagnostics
   • Use of oral quinolones (e.g., levofloxacin) supported by Canadian guidelines
   • Avoid unnecessary parenteral therapy and overtreatment of aspiration pneumonitis
3. Clinical criteria for hospitalisation:
   • Elevated RR, evening onset, dementia, change in mental status
   • Recommends home-based treatment for stable cases
4. Prevention strategies:
   • Pneumococcal and influenza vaccination
   • Oral hygiene improvement (supported by Japanese RCT)
   • Head-of-bed elevation, reflux control
   • Avoidance of feeding tubes in advanced dementia (limited evidence of benefit)

C – Comparison

• No explicit comparator group, but the article synthesises:
  • Home-based vs hospital-based treatment outcomes
  • Oral vs parenteral antibiotic use
  • Vaccination vs non-vaccination
  • NHAP-specific vs community-acquired pneumonia (CAP) approaches

---

O – Outcomes

Person-Centred Outcomes:

• Mortality:
  • 13–41% in hospitalised NHAP patients
  • 7–19% in residents treated in the nursing home
  • Risk factors include dementia, increased RR or pulse, aspiration, and comorbidities 
• Functional outcomes:
  • Residents with “mild” NHAP treated in nursing homes had better 2-month function compared to those hospitalised

Process Outcomes:

• Poor diagnostic workup prior to antibiotic prescribing is common
• Variability in initial treatment decisions and route of administration
• Empirical antibiotic use dominates, with inconsistent adherence to existing guidelines
• Median IM antibiotic course in NHs = 3 days vs IV course in hospital = 5 days

Health System Outcomes:

• Most NHAP cases managed in nursing homes (63%–78%)
• Cost and quality implications of avoiding unnecessary hospital transfers
• Influenza vaccination reduces NHAP risk and hospitalisations
• Oral care interventions reduce pneumonia incidence (RCT in Japan)
• Potential cost-savings and resistance mitigation if aspiration pneumonitis is not misclassified as bacterial pneumonia

Summary Conclusion

This comprehensive review highlights the high burden of NHAP, ongoing challenges in accurate diagnosis, and wide variability in treatment practices. It advocates for empirical use of oral quinolones, supports non-hospital management for stable patients, and underscores the need for improved prevention through vaccination and oral care. Despite the lack of RCTs for NHAP, available evidence suggests that more nuanced, guideline-aligned approaches can reduce morbidity and costs, though implementation barriers persist in many nursing homes .
