The source of infection may be suggested by the instrumentation, as follows: Sinusitis, tracheitis, pneumonia Intravascular catheter: Phlebitis, line infection Foley catheter: UTI Patients with pneumonia may have the following: Fever, cough, purulent sputum Abnormal chest auscultatory findings eg, decreased breath sounds, crackles, wheezes Patients with UTI may have the following: Fever or normal temperature Tenderness, suprapubic cystitis or costovertebral pyelonephritis Cloudy, foul-smelling urine See Clinical Presentation for more detail.

Hospital-Acquired Infections: Practice Essentials, Background, Pathophysiology

Diagnosis Because not all bacterial or fungal growth on a culture is pathogenic and because such growth may reflect simple microbial colonization, interpretation of cultures should take into account the following: Clinical presentation of the patient Reason for obtaining the test Process by which the specimen was obtained Presence or absence of other supporting evidence of infection Methods used to diagnose and characterize BSIs include the following: Differential time to positivity of paired blood cultures simplest [ 8 ] Thesis about nosocomial infection quantitative culture of blood obtained from the catheter and peripheral vein; quantitative culture of catheter segment Suspected fungal infection: Imaging studies such as echocardiography Immunocompromised patients: Occasional special studies eg, cultures for Nocardia, atypical mycobacteria, cytomegalovirus [CMV], and CMV antigenemia Tests used to identify pneumonia include the following: Acute-phase reactants Oxygen saturation and hemodynamic studies Chest radiography Sputum Gram stain and culture if necessary, samples can also be obtained through bronchoalveolar lavage or thoracocentesis Rapid diagnostic tests eg multiplex PCR capable of identifying multiple pathogens in a specimen Urinalysis and urine culture, along with clinical findings, are essential for differentiating between asymptomatic bacteriuria, cystitis, and pyelonephritis.

The following factors should be kept in mind in the interpretation of urine cultures: Number of colonies and species isolated Method of sample collection Time from collection to laboratory processing Sex of the patient Most experts recommend imaging studies in evaluating children with first-time UTI.

See Workup for more detail. Management of BSI may include the following: Line removal as appropriate [ 8 ] Antibiotic therapy covering gram-positive and gram-negative organisms, started empirically and then tailored according to specific susceptibility patterns Antifungal therapy as appropriate Prevention through use of catheter disinfection caps Management of pneumonia includes the following: Initial empiric broad-spectrum antibiotic therapy, later streamlined on the basis of identified organisms and susceptibilities, with attention to the risk of multidrug-resistant MDR pathogens Antiviral medications against influenza for symptomatic patients and patients with immunodeficiency or chronic lung diseases to limit morbidity and mortality Management of UTI includes the following: Removal of indwelling catheters if possible Empiric antibiotic and antifungal therapy Management of SSI includes the following: Surgical debridement See Treatment and Medication for more detail.

Examples include visitors, medical personnel, equipment and the healthcare environment. Inthe Centers for Disease Control and Prevention CDC released a pair of reports on healthcare-associated infections, with one indicating that significant progress has been made in their prevention.Nosocomial Infections Project instructions: complete a literature search, and identify at least three research studies (nursing research preferred) about NOSOCOMIAL INFECTIONS.
