Abstract
Objective Pneumonia is a common and serious infectious disease that affects the older adult population. Severe pneumonia can lead to high mortality and morbidity in this group. Therefore, it is important to identify the risk factors and develop a prediction model for severe pneumonia in older adult patients. Method In this study, we collected data from 1,000 older adult patients who were diagnosed with pneumonia and admitted to the intensive care unit (ICU) in a tertiary hospital. We used logistic regression and machine learning methods to analyze the risk factors and construct a prediction model for severe pneumonia in older adult patients. We evaluated the performance of the model using accuracy, sensitivity, specificity, area under the receiver operating characteristic curve (AUC), and calibration plot. Result We found that age, comorbidities, vital signs, laboratory tests, and radiological findings were associated with severe pneumonia in older adult patients. The prediction model had an accuracy of 0.85, a sensitivity of 0.80, a specificity of 0.88, and an AUC of 0.90. The calibration plot showed good agreement between the predicted and observed probabilities of severe pneumonia. Conclusion The prediction model can help clinicians to stratify the risk of severe pneumonia in older adult patients and provide timely and appropriate interventions.

Abstract
IMPORTANCE This study on bacteremic nosocomial pneumonia (bNP) demonstrates the importance of this condition both in patients undergoing and not undergoing mechanical ventilation. Staphylococcus aureus, Enterobacterales, and non-fermenting Gram-negative bacilli are all causative agents in ventilator-associated pneumonia (VAP) and hospital-acquired pneumonia (HAP), with a predominance of S. aureus in HAP and of Pseudomonas aeruginosa in VAP. Mortality in this condition is very high. Therefore, new therapeutic and preventive approaches should be sought.

Am J Infect Control 2023; 51:1324-1328. [PMID: 37295678 DOI: 10.1016/j.ajic.2023.06.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2023] [Revised: 05/31/2023] [Accepted: 06/03/2023] [Indexed: 06/12/2023]
Abstract
BACKGROUND Our aim was to evaluate the effectiveness of an intervention to reduce the incidence of non-ventilator-associated hospital-acquired pneumonia (NV-HAP) and determine compliance with preventive measures. METHODS This was a quasi-experimental before-after study involving patients in the 53-bed Internal Medicine ward in a university hospital in Spain. The preventive measures included hand hygiene, dysphagia detection, head-of-bed elevation, withdrawal of sedatives in the event of confusion, oral care, and sterile or bottled water use. A prospective post-intervention study of the incidence of NV-HAP was carried out from February 2017 to January 2018 and compared with baseline incidence (May 2014 to April 2015). Compliance with preventive measures was analyzed with 3-point-prevalence studies (December 2015, October 2016, and June 2017). RESULTS The rate of NV-HAP decreased from 0.45 cases (95% confidence interval 0.24-0.77) in the pre-intervention period to 0.18 cases per 1,000 patient-days (95% confidence interval 0.07-0.39) in the post-intervention period (P = .07). Compliance with most preventive measures improved after intervention and remained stable over time. CONCLUSIONS The strategy improved the adherence to most of the preventive measures, with a decrease in the incidence of NV-HAP. Efforts to enhance adherence to such fundamental preventive measures are critical to lowering the incidence of NV-HAP.

Non-ventilator-associated ICU-acquired pneumonia (NV-ICU-AP) in patients with acute exacerbation of COPD: From the French OUTCOMEREA cohort. Crit Care 2023; 27:359. [PMID: 37726796 PMCID: PMC10508006 DOI: 10.1186/s13054-023-04631-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Accepted: 08/30/2023] [Indexed: 09/21/2023] Open
Abstract
BACKGROUND Non-ventilator-associated ICU-acquired pneumonia (NV-ICU-AP), a nosocomial pneumonia that is not related to invasive mechanical ventilation (IMV), has been less studied than ventilator-associated pneumonia, and never in the context of patients in an ICU for severe acute exacerbation of chronic obstructive pulmonary disease (AECOPD), a common cause of ICU admission. This study aimed to determine the factors associated with NV-ICU-AP occurrence and assess the association between NV-ICU-AP and the outcomes of these patients. METHODS Data were extracted from the French ICU database, OutcomeRea™. Using survival analyses with competing risk management, we sought the factors associated with the occurrence of NV-ICU-AP. Then we assessed the association between NV-ICU-AP and mortality, intubation rates, and length of stay in the ICU. RESULTS Of the 844 COPD exacerbations managed in ICUs without immediate IMV, NV-ICU-AP occurred in 42 patients (5%) with an incidence density of 10.8 per 1,000 patient-days. In multivariate analysis, prescription of antibiotics at ICU admission (sHR, 0.45 [0.23; 0.86], p = 0.02) and no decrease in consciousness (sHR, 0.35 [0.16; 0.76]; p < 0.01) were associated with a lower risk of NV-ICU-AP. After adjusting for confounders, NV-ICU-AP was associated with increased 28-day mortality (HR = 3.03 [1.36; 6.73]; p < 0.01), an increased risk of intubation (csHR, 5.00 [2.54; 9.85]; p < 0.01) and with a 10-day increase in ICU length of stay (p < 0.01). CONCLUSION We found that NV-ICU-AP incidence reached 10.8/1000 patient-days and was associated with increased risks of intubation, 28-day mortality, and longer stay for patients admitted with AECOPD.

Mao X, Yang Z. Association between hospital-acquired pneumonia and proton pump inhibitor prophylaxis in patients treated with glucocorticoids: a retrospective cohort study based on 307,622 admissions in China. J Thorac Dis 2022; 14:2022-2033. [PMID: 35813745 PMCID: PMC9264073 DOI: 10.21037/jtd-21-1886] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2021] [Accepted: 05/12/2022] [Indexed: 11/06/2022]
Abstract
Background Prophylaxis with proton pump inhibitor (PPI) in patients treated with glucocorticoid therapy is a common phenomenon in the general wards of Chinese hospitals. Many of these prescriptions are inappropriate and lead to overuse. Hospital-acquired pneumonia (HAP) is a possible adverse effect for this combination but remains controversial. Methods We designed a retrospective cohort study using electronic medical record databases from multiple hospitals to investigate whether PPI prophylaxis increases the risk of HAP in hospitalized patients receiving glucocorticoid therapy. The study population was adult patients who were not critical and treated with at least 1 dose of glucocorticoid during hospitalization and the exposure factor was PPIs prophylaxis. The odds ratio of HAP between the exposed and unexposed groups was calculated based on the cohort which was established by propensity score matching. The dose-effect relationship between PPI prophylaxis and HAP was also evaluated. Results Among the 307,622 admissions eligible for the study, a total of 217,460 (70.7%) admissions had a record of PPI prophylaxis. After reconstructed the cohort by propensity score matching, the exposed and unexposed groups both included 83,786 admissions. The incidence of HAP in the exposed group was higher than that in the unexposed group (2.1% vs. 1.5%, OR: 1.4, 95% CI: 1.3 to 1.5). The risk of HAP increased when the cumulative dose of PPI during hospital was more than 2 defined drug doses. Compared to the unexposed group, the adjusted odds ratio was 1.3 (95% CI: 1.2 to 1.4) in the medium-dose group (2-7 defined drug doses) and 1.9 (95% CI: 1.8 to 2.1) in the high-dose group (>7 defined drug doses). Conclusions PPI prophylaxis increased the risk of HAP in hospitalized patients treated with glucocorticoid therapy and the risk of HAP increased as the dose of PPIs accumulated.
