CONTEXT Traditionally, pneumonia developing in patients outside the hospital is categorized as community acquired, even if these patients have been receiving health care in an outpatient facility. Accumulating evidence suggests that health-care-associated infections are distinct from those that are truly community acquired. OBJECTIVE To characterize the microbiology and outcomes among patients with culture-positive community-acquired pneumonia (CAP), health-care-associated pneumonia (HCAP…

Outcomes of patients hospitalized with community-acquired, health care-associated, and hospital-acquired pneumonia.
Health care-associated pneumonia should be considered a distinct subset of pneumonia associated with more severe disease, longer hospital stay, and higher mortality rates, according to international guidelines.
Health Care-Associated Pneumonia and Community-Acquired Pneumonia: a Single-Center Experience
The study found that the incidence of HCAP was greater than that of CAP among patients with culture-positive pneumonia requiring hospitalization at Barnes-Jewish Hospital, and patients with HCAP were more likely to initially receive inappropriate antimicrobial treatment and had a greater risk of hospital mortality.
Health Care-Associated Pneumonia
A greater recognition of HCAP as a new class of pneumonia with a distinct epidemiologic, microbiologic, and clinical profile should lead physicians to initiate appropriate empiric antibiotic therapy more often, thereby improving the likelihood for optimal clinical outcomes and patient care.
Health care-associated pneumonia requiring hospital admission: epidemiology, antibiotic therapy, and clinical outcomes.
At present, a substantial number of patients initially seen with pneumonia in the emergency department have HCAP, and these patients require a targeted approach when selecting empirical antibiotic therapy.

Since the causative organisms of HCAP were closely related to those of hospital-acquired pneumonia and not to community- Acquired pneumonia, it is believed that aggressive chemotherapy using broad-spectrum antimicrobials is needed in the initial treatment.

It is essential for physicians to be capable of recognizing risk factors for HCAI and HCAP as well as competently select and implement appropriate treatment strategies.
Health-care-associated pneumonia among hospitalized patients in a Japanese community hospital.
The present study provides additional evidence that HCAP should be distinguished from CAP, and suggests that the therapeutic strategy for HCAP in the moderate class holds the key to improving mortality.
Health care-associated pneumonia: an evidence-based review.


Epidemiology and outcomes of ventilator-associated pneumonia in a large US database.
It is demonstrated that VAP is a common nosocomial infection that is associated with poor clinical and economic outcomes and strategies to prevent the occurrence of VAP may not reduce mortality, but they may yield other important benefits to patients, their families, and hospital systems.
Health CareAssociated Bloodstream Infections in Adults: A Reason To Change the Accepted Definition of Community-Acquired Infections
A new classification scheme for bloodstream infections is sought that distinguishes among and compares patients with community-acquired, health careassociated, and nosocomial infections.
Community-acquired pneumonia: the annual cost to the National Health Service in the UK.
Community-acquired pneumonia in the UK incurs a direct healthcare cost of 440.7 million pounds annually at 1992/1993 prices, and developing and implementing strategies to prevent and minimize hospitalization will significantly reduce this annual cost.
A prediction rule to identify low-risk patients with community-acquired pneumonia.
A prediction rule that stratifies patients into five classes with respect to the risk of death within 30 days accurately identifies the patients with community-acquired pneumonia who are at low risk for death and other adverse outcomes and may help physicians make more rational decisions about hospitalization for patients with pneumonia.
Prognosis and outcomes of patients with community-acquired pneumonia. A meta-analysis.
Mortality for patients hospitalized with CAP was high and was associated with characteristics of the study cohort, pneumonia etiology, and a variety of prognostic factors.
Guidelines for community-acquired pneumonia in the ICU
These guidelines have developed prediction tools to direct clinicians in the management of community-acquired pneumonia, including when to admit a patient to the ICU and selecting appropriate investigations and antimicrobial therapy.

Community-acquired Pneumonia: Compliance with Centers for Medicare and Medicaid Services, National Guidelines, and Factors Associated with Outcome
Using the most recent CAP guidelines as a benchmark may lower compliance unless providers are reeducated, and antibiotics should be started within 4 hours in patients with CAP.
Comparison of community- and health care-associated methicillin-resistant Staphylococcus aureus infection.
It is suggested that most community-associated MRSA strains did not originate in health care settings, and that their microbiological features may have contributed to their emergence in the community.
