Clinical Stability

The soluble form of the suppression of tumorigenicity-2 (sST2) is a biomarker for risk classification and prognosis of heart failure, and its production and secretion in the alveolar epithelium are significantly correlated with the inflammation-inducing in pulmonary diseases. However, the predictive value of sST2 in pulmonary disease had not been widely studied. This study investigated the potential value in prognosis and risk classification of sST2 in patients with community-acquired pneumonia. Clinical data of ninety-three CAP inpatients were retrieved and their sST2 and other clinical indices were studied. Cox regression models were constructed to probe the sST2’s predictive value for patients’ restoring clinical stability and its additive effect on pneumonia severity index and CURB-65 scores. Patients who did not reach clinical stability within the defined time (30 days from hospitalization) have had significantly higher levels of sST2 at admission ( P <  0.05). In univariate and multivariate Cox regression analysis, a high sST2 level (≥72.8 ng/mL) was an independent reverse predictor of clinical stability ( P < 0.05). The Cox regression model combined with sST2 and CURB-65 (AUC: 0.96) provided a more accurate risk classification than CURB-65 (AUC:0.89) alone (NRI: 1.18, IDI: 0.16, P < 0.05). The Cox regression model combined with sST2 and pneumonia severity index (AUC: 0.96) also provided a more accurate risk classification than pneumonia severity index (AUC:0.93) alone (NRI: 0.06; IDI: 0.06, P < 0.05). sST2 at admission can be used as an independent early prognostic indicator for CAP patients. Moreover, it can improve the predictive power of CURB-65 and pneumonia severity index score.

Clinical Stability

Early clinical stability has been proven to be vital for the treatment of community-acquired pneumonia (CAP). This research retrospectively analyzed the predictive implication of neutrophil–lymphocyte ratio (NLR) and confusion, urea >7 mmol/L, respiratory rate ⩾30 breaths/min, low blood pressure, and age ⩾65 years (CURB-65) score to predict early clinical stability of the adult CAP. Clinical data, CURB-65 scores, pneumonia severity index (PSI) scores, NLR on admission (within 24 h) of 230 patients between January 2012 and June 2015 were obtained from the Affiliated Hospital of Chengdu University. Instable patients had significantly higher CURB-65, PSI, white blood cell (WBC), neutrophil, and NLR than the stable patients ( P < 0.05); NLR was positively correlated with CURB-65 (r = 0.270, P < 0.001) and PSI (r = 0.316, P < 0.001). NLR and CURB-65 were screened as risk factors through the discriminant analysis. The area under the curve (AUC) was 0.662 (95% confidence interval (CI): (0.569, 0.756), P = 0.002) for NLR, 0.670 (95% CI (0.569, 0.772) P = 0.001) for CURB-65. The enhanced predictive power was observed for combining NLR-CURB-65 with the AUC of 0.704 (95% CI (0.606, 0.802), P < 0.001). The risk of early clinical instability rose significantly in patients with NLR (odds ratio (OR) = 3.440, 95% CI (1.741, 6.798) with the cut-off value of NLR = 6.161) and higher CURB-65 (OR = 3.797, 95% CI (1.801, 8.005), with the CURB-65 cut-off value of 1.5). Both NLR and CURB-65 are qualitatively accurate for predicting early clinical stability of CAP, an accuracy-enhanced predicting power was observed in the NLR-CURB-65 combined test, further large-sample studies are required to validate the conclusion.

BACKGROUND: Patients admitted to Lions Gate Hospital, North Vancouver, British Columbia, with a primary diagnosis of community-acquired pneumonia (CAP) have a mean length of stay (LOS) of 9.1 days compared with 7.9 days for peer group hospitals. This difference of 1.2 days results in an annual potential savings of 406 bed days and warranted an investigation into the management of CAP.OBJECTIVE: To characterize and provide recommendations for the management of CAP.METHODS: A retrospective chart review of patients admitted with a primary diagnosis of CAP between May 1, 2000 and August 31, 2000.RESULTS: Fifty-one patients were included in the study, with a mean LOS of 9.9 days and a median LOS of five days. Based on pneumonia severity index scores calculated for each patient, eight patients (16%) were admitted inappropriately. Initial empirical antibiotic choices were consistent with the Canadian CAP guidelines in 27 patients (53%), with inconsistencies arising mainly because cephalosporin or azithromycin monotherapy regimens were prescribed. Step-down from intravenous to oral antibiotics occurred in approximately 20 patients (39%). An additional 12 patients (24%) could have undergone step-down, and step-down was not applicable in 19 patients (37%). The potential annual cost avoidance from implementing admission criteria based on a pneumonia severity index score, applying step-down criteria and promoting early discharge criteria was estimated to be $220,000.CONCLUSIONS: Considerable variability exists in the treatment of CAP. A CAP preprinted order sheet was developed to address the issues identified in the present study and provide consistency in the management of CAP at Lions Gate Hospital.
