Introduction The traditional classification of Pneumonia as either community acquired (CAP) or hospital acquired (HAP) reflects deep differences in the etiology, pathogenesis, approach and prognosis between the two entities. Health-Care Associated Pneumonia (HCAP) develops in a heterogeneous group of patients receiving invasive medical care or surgical procedures in an outpatient setting. For epidemiology and outcomes, HCAP closely resembles HAP and possibly requires an analogous therapeutic regimen effective against multidrug-resistant pathogens. Materials and methods We reviewed the pertinent literature and the guidelines for the diagnosis and management of HCAP to analyze the evidence for the recommended approach. Results Growing evidence seems to confirm the differences in epidemiology and outcome between HCAP and CAP but fails to confirm any real advantage in pursuing an aggressive treatment for all HCAP and CAP patients. Discussion Further investigations are needed to establish the optimal treatment approach according to the different categories of patients and the different illness severities.

Hospital Acquired

Pneumonia can be classified as: community-acquired pneumonia (CAP), hospital-acquired pneumonia (HAP), ventilator-associated pneumonia (VAP), healthcare-associated pneumonia (HCAP), and pneumonia in immunosuppressed patients. Although the above are similar pathologically, they are very different from a clinical perspective. Chest radiography is often performed to support the diagnosis and to determine the extent of involvement prior to the onset of therapy. Radiography should not be performed in the short term in patients who are improving clinically as it can lead to the misdiagnosis of treatment failure. Chest radiography in patients treated for pneumonia should only be obtained before 4-6 weeks after the onset of therapy if there is a failure of clinical response or if complications of pneumonia are clinically suspected. The majority of pneumonias will resolve after 6 weeks of appropriate antibiotic therapy.

Abstract Background We aimed to compare the clinical characteristics of patients with community-acquired pneumonia (CAP), healthcare-associated pneumonia (HCAP), and hospital-acquired pneumonia (HAP) caused by Klebsiella pneumoniae and analyze the antimicrobial resistance and proportion of hypervirluent strains of the microbial isolates. Methods We conducted a retrospective study on patients with pneumonia caused by K. pneumoniae at the Taipei Veterans General Hospital in Taiwan between January 2014 and December 2016. To analyze the clinical characteristics of these patients, data was extracted from their medical records. K. pneumoniae strains were subjected to antimicrobial susceptibility testing, capsular genotyping and detection of the rmpA and rmpA2 genes to identify hypervirulent strains. Results We identified 276 patients with pneumonia caused by K. pneumoniae, of which 68 (24.6%), 74 (26.8%), and 134 (48.6%) presented with CAP, HCAP, and HAP, respectively. The 28-day mortality was highest in the HAP group (39.6%), followed by the HCAP (29.7%) and CAP (27.9%) groups. The HAP group also featured the highest proportion of multi-drug resistant strains (49.3%), followed by the HCAP (36.5%) and CAP groups (10.3%), while the CAP group had the highest proportion of hypervirulent strains (79.4%), followed by the HCAP (55.4%) and HAP groups (41.0%). Conclusion Pneumonia caused by K. pneumoniae was associated with a high mortality. Importantly, multi-drug resistant strains were also detected in patients with CAP. Hypervirulent strains were prevalent in all 3 groups of pneumonia patients, even in those with HAP.

Symptoms And Signs

Pneumonia is defined as acute infection of the pulmonary parenchyma, presenting with consistent symptoms and signs and associated with new radiographic shadowing. It may be acute or chronic in onset and involve either one area of a lung (e.g. lobar pneumonia) or be multifocal in nature. It may be community acquired or hospital acquired. Community- acquired pneumonia is defined as pneumonia occurring in an individual with no recent contact with a healthcare setting, or in a patient admitted to hospital with development of symptoms and/or signs of pneumonia within 48 hours of admission. Hospital-acquired pneumonia or nosocomial pneumonia occurs when a patient develops symptoms or signs of pneumonia after 48 hours of admission to a healthcare setting or in the context of a long-term nursing home resident. A subtype of nosocomial pneumonia is ventilator-associated pneumonia, defined as pneumonia occurring at least 48–72 hours post intubation.

IntroductionTo describe the incidence and compare in-hospital outcomes of community-acquired pneumonia (CAP), ventilator-associated pneumonia (VAP) and non-ventilator hospital-acquired pneumonia (NV-HAP) among patients with or without type 2 diabetes mellitus (T2DM) using propensity score matching.Research design and methodsThis was a retrospective observational epidemiological study using the 2016–2017 Spanish Hospital Discharge Records.ResultsOf 245 221 admissions, CAP was identified in 227 524 (27.67% with T2DM), VAP was identified in 2752 (18.31% with T2DM) and NV-HAP was identified in 14 945 (25.75% with T2DM). The incidence of pneumonia was higher among patients with T2DM (CAP: incidence rate ratio (IRR) 1.44, 95% CI 1.42 to 1.45; VAP: IRR 1.24, 95% CI 1.12 to 1.37 and NV-HAP: IRR 1.38, 95% CI 1.33 to 1.44). In-hospital mortality (IHM) for CAP was 12.74% in patients with T2DM and 14.16% in matched controls (p<0.001); in patients with VAP and NV-HAP, IHM was not significantly different between those with and without T2DM (43.65% vs 41.87%, p=0.567, and 29.02% vs 29.75%, p=0.484, respectively). Among patients with T2DM, older age and dialysis were factors associated with IHM for all types of pneumonia. In patients with VAP, the risk of IHM was higher in females (OR 1.95, 95% CI 1.28 to 2.96).ConclusionThe incidence rates of all types of pneumonia were higher in patients with T2DM. Higher mortality rates in patients with T2DM with any type of pneumonia were associated with older age, comorbidities and dialysis.

Common Infection

: One of the most dangerous respiratory diseases is pneumonia, one of the ten leading causes of death globally. Hospital-acquired pneumonia (HAP) is a common infection in hospitals, which is the second most common nosocomial infection and causes inflammation parenchyma. In Community-acquired pneumonia (CAP), we have various risk factors, including age and gender, and also some specific risk factors. Ventilator-associated pneumonia (VAP) is one of the deadliest nosocomial infections. According to the Centers for Disease Control and Prevention, VAP is pneumonia that develops about 48 hours of an artificial airway. Bacterial, viral, parasitic, primordial, and other species can cause these diseases. We discuss bacterial factors. Our goal is to gather information about HAP, CAP, and VAP to give people specific information. In this study, these three issues have been examined together, but in similar studies, each of them has been examined separately, and our type of study will be more helpful in diagnosis and treatment.

This study of ventilated patients investigated pneumonia risk factors and outcome predictors in 476 episodes of pneumonia (48% community-acquired pneumonia, 24% hospital-acquired pneumonia, 28% ventilator-associated pneumonia) using a prospective survey in 14 intensive care units within Australia and New Zealand. For community acquired pneumonia, mortality increased with immunosuppression (OR 5.32, CI 95% 1.58–17.99, P<0.01), clinical signs of consolidation (OR 2.43, CI 95% 1.09–5.44, P=0.03) and Sepsis-Related Organ Failure Assessment (SOFA) scores (OR 1.19, CI 95% 1.08–1.30, P<0.001) but improved if appropriate antibiotic changes were made within three days of intensive care unit admission (OR 0.42, CI 95% 0.20–0.86, P=0.02). For hospital-acquired pneumonia, immunosuppression (OR 6.98, CI 95% 1.16–42.2, P=0.03) and non-metastatic cancer (OR 3.78, CI 95% 1.20–11.93, P=0.02) were the principal mortality predictors. Alcoholism (OR 7.80, CI 95% 1.20–17.50, P<0.001), high SOFA scores (OR 1.44, CI 95% 1.20–1.75, P=0.001) and the isolation of “high risk” organisms including Pseudomonas aeruginosa, Acinetobacter spp, Stenotrophomonas spp and methicillin resistant Staphylococcus aureus (OR 4.79, CI 95% 1.43–16.03, P=0.01), were associated with increased mortality in ventilator-associated pneumonia. The use of non-invasive ventilation was independently protective against mortality for patients with community-acquired and hospital-acquired pneumonia (OR 0.35, CI 95% 0.18–0.68, P=0.002). Mortality was similar for patients requiring both invasive and non-invasive ventilation and non-invasive ventilation alone (21% compared with 20% respectively, P=0.56). Pneumonia risks and mortality predictors in Australian and New Zealand ICUs vary with pneumonia type. A history of alcoholism is a major risk factor for mortality in ventilator-associated pneumonia, greater in magnitude than the mortality effect of immunosuppression in hospital-acquired pneumonia or community-acquired pneumonia. Non-invasive ventilation is associated with reduced ICU mortality. Clinical signs of consolidation worsen, while rationalising antibiotic therapy within three days of ICU admission improves mortality for community-acquired pneumonia patients.
