Infection from hospitals, causes

Risk factors for developing an infection caused by a resistant pathogen generally are related to the prior use of antibiotics, insertion of catheters or other invasive devices, and hospitalization in a unit contaminated/colonized with resistant organisms. The following is a more complete list of factors influencing infection from a resistant organism ... 

Insomnia can have a serious impact on a person s quality of life. Acute insomnia can lead to daytime sleepiness and reduced ability to concentrate, remember things, use logical reasoning, and even impair your ability to drive a car. Chronic insomnia can have major health consequences, such as an increased susceptibility to depression and some forms of heart disease and a reduced ability to fight off colds or infections. There is also a tremendous cost to society caused by insomnia—billions of dollars are spent each year on treatment, healthcare services, and hospital costs. An equal cost can be attributed to lost productivity at work and property and personal damage from accidents caused by sleepy insomniacs. 

PenicBlins Resistant to Pemditnase. Modification of the penicillin structure produced a group of drugs including methicillin, oxacillin, cloxacillin, dicloxacillin, and nafcillin that are not susceptible to staphylococcal penicillinase. Their appropriate use is in the treatment of infections caused by strains of Staphylococcus aureus and Staphylococcus epidermidis that produce penicillinase. These include most strains isolated from hospital settings and the general commimity. 

Over the last six decades, however, increased use of antimicrobial drugs, not only in human medicine, but in other areas, such as veterinary medicine, agriculture, and fish farming, has had an enormous impact on the microbial society. Nearly everywhere, the numbers of susceptible strains have reduced and resistant strains or variants have increased in numbers. It has been repeatedly reported that the susceptibility profile of bacteria in any human compartment, such as the skin, intestine, and respiratory tract, is very different from what it was in the pre-antibiotic era, and even 15 years ago. The same trend is reported from hospitals and homes. Multidrug resistance, that is resistance to several antimicrobial drugs, is commonly found in bacteria that cause infections as well as in commensal organisms. 

The use of an indwelling catheter frequently is associated with infection of the urinary tract and represents the most common cause of hospital-acquired infection. The incidence of catheter-associated infection is related to a variety of factors, including method and duration of catheterization, the catheter system (open or closed), the care of the system, the susceptibility of the patient, and the technique of the health care personnel inserting the catheter. The incidence of infection from a single catheterization in a healthy ambulatory patient is 1%. Bacteria may enter the bladder in a number of ways. During the catheterization, bacteria may be introduced directly into the bladder from the urethra. Once the catheter is in place, bacteria may pass up the lumen of the catheter via the movement of air bubbles, by motility of the bacteria, or by capillary action. In addition, bacteria may reach the bladder from around the exudative sheath that surrounds... 

Staphylococcus species are prominent pathogenic microorganisms encountered in postsurgical infections of normal individuals, in immunocompromised patients, and in elderly hospitalized medical patients [1], Staphylococcus species were among the earliest pathogenic bacteria characterized, and, aside from hospital-acquired infections, they are the most common cause of localized suppurative infections in humans. 

Over the years, incidence of hospital-acquired S. aureus infections has increased. It is the causative agent in about 50% of the catheter-related bacteremias, the majority of hospital-acquired infections from the insertion of prosthetic devices, and the majority of cases of septic arthritis and osteomyelitis [7]. 

As the success of this and related programmes became apparent, a much wider intervention was launched led by the Michigan Health and Hospital Keystone Association for Patient Safety and Quality. 108 Michigan ICUs took part in an 18-month intervention programme aimed particularly at decreasing catheter related bloodstream infections, a common, costly and potentially lethal complication of ICU care. In the United States, 80 000 patients each year were affected, with up to 28 000 deaths in intensive care units from this cause. 

Infections caused by methicillin-resistant Staphylococcus aureus (MRSA) in already hospitalised patients or with week immune systems pose a serious problem all over the world because MRSA strains are resistant to numerous antibiotics and can be transmitted from patient to patient via transiently colonised hands of hospital personnel (Mulligan et al. 1993). Vancomycin is the most used antibiotic for MRSA infections, but some problems can occur, such as side effects or infections from vancomycin resistant enterococci (Schouten et al. 2000). For these reasons, use of flavonoids alone or in combination with traditional antibiotics has been considered as an alternative for treating MRSA infections (Pathak et al. 1991). 

Stoll et al. (2002b) examined provider costs in a German monocentric cohort of HIV-infected patients after the introduction of HA ART. According to their findings, mean provider costs per capita decreased from US 31,812 in 1997 to US 21,926 in 2001. The costs of HA ART per capita decreased significantly from US 15,739 in 1997 to US 14,336 in 2001. Also quite impressive was the continuous decrease of expenditures for additional drug therapy (-43.3%) and hospitalization (-52.1%), respectively. However, the costs caused by HAART increased from 49.5% of all provider costs in 1997 to 65.4% in 2001. 

Pneumonia is inflammation of the lung with consolidation. The cause of the inflammation is infection, which can result from a wide range of organisms. There are five classifications of pneumonia community-acquired, aspiration, hospital-acquired, ventilator-associated, and health care-associated. Patients who develop pneumonia in the outpatient setting and have not been in any health care facilities, which include wound care and hemodialysis clinics, have community-acquired pneumonia (CAP). Aspiration is of either oropharyngeal or gastrointestinal contents. Hospital-acquired pneumonia (HAP) is defined as pneumonia that occurs 48 hours or more after admission.1,2 Ventilator-associated pneumonia (VAP) requires endotracheal intubation for at least 48 to 72 hours before the onset of... 

The primary goals of treatment are correction of the intraabdominal disease processes or injuries that have caused infection and drainage of collections of purulent material (abscess). A secondary objective is to resolve the infection without major organ system complications (e.g., pulmonary, hepatic, cardiovascular, or renal failure) or adverse drug effects. Ideally, the patient should be discharged from the hospital with full function for self-care and routine daily activities.
