18 Severity Assessment The key to deciding initial site of care Outpatient Medical ward Critical care ward / ICU Severity assessment is made on the basis of prognostic criteria: patients age comorbidities physical, laboratory and radiographic findings

19 Severity assessment & Prognostication Severity of illness score (e.g., CURB-65) Prognostic models (e.g., PSI) can be used to identify patients who may be treated as outpatients (Strong recommendation; level I evidence) IDSA / ATS Consensus Guidelines on the management of CAP in adults. Clin Infect Dis 2007; 44:S27-72

20 Severity Assessment Pneumonia Severity Index (PSI) Requires computation of a score based on 20 variables Fine MJ, et al. A prediction rule to identify low-risk patients with CAP. N Engl J Med 1997;336:243-50

21 Severity Assessment Pneumonia Severity Index (PSI) stratifies patients into 5 mortality risk classes: Risk Risk class Score 30-day mortality Low I No predictors 0.1% Low II < % Low III % Moderate IV % High V > % Fine MJ, et al. A prediction rule to identify low-risk patients with CAP. N Engl J Med 1997;336:243-50

22 Severity Assessment Pneumonia Severity Index (PSI) On the basis of associated mortality rates, patients in Risk class 30-day mortality I 0.1% II 0.6% III 0.9% IV 9.3% V 27.0% Treat as outpatients Treat in an observation unit or short hospitalisation Treat as inpatients Fine MJ, et al. A prediction rule to identify low-risk patients with CAP. N Engl J Med 1997;336:243-50

23 Severity Assessment CURB-65 score (6-point) adopted by BTS Score 1 point for each feature present Confusion Urea > 7 mmol/l Respiratory rate > 30/min Blood pressure (SBP < 90 mmhg or DBP < 60 mmhg) Age > 65 yrs Lim WS, et al. Thorax 2003;58:

24 CURB-65 score Risk of mortality Score 0 0.7% Score 1 3.2% Recommendations Patients who have a CURB-65 score of 0 or 1 are at low risk of death - can be treated as having non-severe pneumonia and may be suitable for home treatment Score 2 13% Score 3 17% Score % Score 5 57% At increased risk of death - should be considered for short stay inpatient treatment or hospital supervised outpatient treatment (use clinical judgement) Patients who have a CURB-65 score of 3 or more are at high risk of death and should be managed as severe pneumonia Lim WS, et al. Thorax 2003;58:

25 There is growing evidence that CURB, CURB-65 and CRB-65 all allow for similar predictions of death from CAP as compared to the PSI

26 A prospective observational study of 1016 consecutive inpatients with CAP in an Emergency Department mean (SD) age: 72 (+ 17) yrs The ability of the three rules to predict 30 day mortality was compared Yan Man S, et al. Prospective comparison of 3 predictive rules (PSI, CURB-65, CRB-65) for assessing severity of CAP (and to predict 30-day mortality) in Hong Kong. Thorax 2007; 62:

27 PSI class 30-day mortality (%) I 0 II 0.8 III 5 IV 9.3 V 22.1 CURB CRB All 3 predictive rules showed the same trend of increasing mortality with worsening risk groups (p <0.001) 4 40 Yan Man S, et al. Prospective comparison of 3 predictive rules for assessing severity of CAP in Hong Kong. Thorax 2007; 62:

28 Sensitivity, specificity, positive and negative predictive values of 30 day mortality of the different predictive rules All 3 clinical decision rules had high negative predictive values but low positive predictive values at all cut-off points and are therefore more useful in ruling out serious illness Yan Man S, et al. Prospective comparison of 3 predictive rules for assessing severity of CAP in Hong Kong. Thorax 2007; 62:

29 Sensitivity, specificity, positive and negative predictive values of 30 day mortality of the different predictive rules PSI : complicated computation of a score may not be practical for routine application in busy hospital emergency departments or primary care settings CURB-65 : simpler to apply CRB-65 : is also easily applicable in primary care settings All 3 clinical decision rules had high negative predictive values but low positive predictive values at all cut-off points and are therefore more useful in ruling out serious illness Yan Man S, et al. Prospective comparison of 3 predictive rules for assessing severity of CAP in Hong Kong. Thorax 2007; 62:

30 ICU admission rates also increased with the risk levels of each rule, but were only statistically significant in CURB-65 and CRB-65 Yan Man S, et al. Prospective comparison of 3 predictive rules for assessing severity of CAP in Hong Kong. Thorax 2007; 62:

31 Sensitivity and specificity for high-risk group of the 3 predictive rules in identifying ICU admission Sensitivity (%) Specificity (%) PSI CURB CRB Because of their low sensitivities, none of the 3 rules appears to be useful for identifying patients requiring ICU care Modified ATS rule Ewig S, et al. Severe CAP: assessment of severity criteria. Am J Respir Crit Care Med 1998;158: Yan Man S, et al. Prospective comparison of 3 predictive rules for assessing severity of CAP in Hong Kong. Thorax 2007; 62:

32 Sensitivity and specificity for high-risk group of the 3 predictive rules in identifying ICU admission Sensitivity (%) Specificity (%) PSI CURB CRB Although far from being perfect, the modified American Thoracic Society score is currently the best tool in identifying Because of their low sensitivities, none of the 3 rules appears to be useful for identifying patients requiring patients ICU for care ICU admission Modified ATS rule Ewig S, et al.

33 Site-of-care decisions 1 Prediction rules give an indication of disease severity Prediction rules have not been found to be useful in predicting ICU admission Generally, patients of higher risk classes have higher rates of ICU admission Unlike 30 day mortality, the association is not strong enough to allow for individual predictions and decisions Criteria for ICU admission vary from country to country and from hospital to hospital Criteria for ICU admission: disease severity is not the only factor to consider; other factors to consider: disease prognosis, pre-morbid status, age of patient, and the availability of ICU resources

34 Site-of-care decisions 2 All predictive rules serve only as a guide to clinical management Severity of illness is not the only factor to be considered when deciding on admission Social and home circumstances must be considered as well Physicians should always exercise clinical judgment and common sense in making these decisions

35 Criteria for severe CAP Major criteria Need for mechanical ventilation Septic shock requiring vasopressors 2007 IDSA / ATS Consensus Guidelines

36 Criteria for severe CAP Major criteria Need for mechanical ventilation Septic shock requiring vasopressors Minor criteria Respiratory rate >30 breaths/min PaO 2 /FiO 2 ratio <250 Multilobar infiltrates Confusion/disorientation Uraemia (BUN level, >20 mg/dl) Leukopenia (WBC count, <4 x 10 9 /L) Thrombocytopenia (platelet count, <100 x 10 9 /L) Hypothermia (core temperature, <36ºC) Hypotension requiring aggressive fluid resuscitation 2007 IDSA / ATS Consensus Guidelines

37 ICU admission decision Direct admission to an ICU is required for patients with septic shock requiring vasopressors or with acute respiratory failure requiring intubation and mechanical ventilation (Strong recommendation; level II evidence) Direct admission to an ICU or high-level monitoring unit is recommended for patients with 3 of the minor criteria for severe CAP (Moderate recommendation; level II evidence) Mandell LA, et al.

Arch Intern Med 2004; 164: In the 2003 IDSA guidelines (also JRS guidelines 2005), initiating antibiotic therapy within 4 hrs after registration for hospitalised patients was a performance indicator 2007 IDSA / ATS Consensus Guidelines: Rather than designating a specific window in which to initiate treatment, hospitalized patients with CAP should receive the first antibiotic dose in the ED

46 Antibiotic Resistance Issues Resistance to commonly used antibiotics for CAP is major consideration in choosing empirical therapy Resistance patterns vary by geography Therefore, antibiotic recommendations must be modified based on local susceptibility patterns

76 Adjusted OR for 30-day all-cause mortality plotted against compliance with guideline-recommended antibiotics at Intermountain Healthcare hospitals Adjusted OR for 30-day all-cause mortality Circle area reflects the number of admissions per hospital The odds of mortality are 0.92 (p = 0.007) for each 10% increase in compliance Dean, N. C. et al. Chest 2006;130:

77 Any advantages in following guidelines? Reduction in hospital admission rate Shortens length of hospital stay (LOS) Reduction in in-hospital and 30-day mortality? Help control bacterial resistance in the community (minimise use of excessive antibiotics and improves accuracy of therapy) However, the impact of guidelines on resistance remains to be shown
