Guide to Preventing Central Line-Associated Bloodstream Infections 5 Introduction Prevention of device-associated infection represents a complex challenge for the infection prevention team as well as the many stakeholders involved in those prevention activities. Furthermore, as the characteristics of the host patient become increasingly compromised, it is vital that there be an attention to basic practice coupled with knowledge of process improvement opportunities. A strength of this implementation guide is demonstrated by the collaborative efforts of the many contributors and reviewers who have worked together to compose a document that has been peer-reviewed and is immediately useful in practice. Unlike the short, temporary catheters inserted into the peripheral vasculature, these central devices access major vessels that are most often located in the neck or adjacent to the heart. However, central lines are indicates that it will continue to grow in the years also used in other areas of the hospital and across ahead, with a total value that may surpass $2 billion the continuum of care, as patientstransition to by 2022. It was estimated that 5,520 to 20,239 lives would be saved annually with best practice implementation. The use of checklists and the promotion of safety culture were integral to the success achieved here as well. This project demonstrated not only significant improvements but also sustainability. Forty-four states, the District of Columbia, and Puerto Rico enrolled hospital units in the program. Collectively, more than 1,000 hospitals and 1,800 hospital unit teams participated in the initiative. Estimating the proportion of healthcare-associated infections that are reasonably preventable and the related mortality and costs. The opportunity estimator uses current evidence from multiple studies, and the list of references can be found on the opportunity estimator website. This has allowed the opportunity to collect feedback from tool users and identify opportunities to clarify definitions and update material. It is a measurement (not outcomes reporting) system and can be integrated into an existing quality/performance improvement program. For additional information, including a toolkit, web-based training, and other resources, visit The aim of the 5 Million Lives Campaign was to support the improvement of medical care in the United States, significantly reducing levels of morbidity (illness or medical harm, such as adverse drug events or surgical complications) and mortality. Partnership for Patients Physicians, nurses, hospitals, employers, patients and their advocates, and the federal and state governments have joined together to form the Partnership for Patients (PfP). A reference list of resources, based on those recommended by PfP, is located in the appendix. In the second phase, high-risk post-acute areas were added, specifically, ambulatory surgery centers and hemodialysis centers. Influenza vaccination participation target for healthcare personnel was also included. Ongoing meetings and engagement from a wide variety of stakeholders have been used not only to establish appropriate targets and metrics, but also to improve surveillance and monitor results. Expert committees made up of varied stakeholders, including patients, participate in the standard development process. Nursing care structure is affected by the supply of nursing staff, the skill level of the nursing staff, and the education of nursing staff. Process indicators measure aspects of nursing care, such as assessment, intervention, and registered nurse job satisfaction. Patient outcomes that are determined to be nursing sensitive are those that improve if there is a greater quantity or quality of nursing care. With the Deficit Reduction Act of 2005, the federal government began looking to improve healthcare quality and reduce healthcare spending by limiting Medicare payments for certain adverse impacts. Funding for incentive payments comes from across-the-board reductions of base-operating diagnosis-related group payments for all hospitals. Higher scores indicate worse performance and the 25 percent of hospitals with the highest score will be subject to the 1-percent reduction in Medicare reimbursement.

Other clinical conditions associated with catheter use include mycotic aneurysms and suppurative thromboembolism. In both cases the catheter causes inflammation or damage to the vessel wall that eventually leads to infection. Shortly after insertion, intravascular catheters are coated with the polymeric matrix which consists of fibrin, plasma proteins, and cellular elements, such as platelets and red blood cells. Microbes interact with the conditioning film, resulting in colonization of the catheter. Formation of these sessile communities and their inherent resistance to antimicrobial agents are at the root of many persistent and chronic bacterial infections and often prompt the removal of central lines when organisms are cultured. Although biofilms occur naturally, the current increased association between biofilms and disease reflects changes in medical practices. Biofilms are the preferred method used by microorganisms for survival, especially when environmental selective pressures are present. For example, naturally occurring biofilms are found in drinking water lines, urban water systems, oil recovery equipment, food processing areas, ship hulls, and at any interface between a solid and nonsolid surface. The increased impact of biofilms in medicine is a result of the explosive growth in the past decade or so in the use of both simple and complex indwelling medical devices. However, there is no absolute method for mitigating the risk; all indwelling medical devices are associated with biofilm formation. Various experiments have been conducted to eliminate intraluminal biofilms through the use of antibiotics, ethanol, and thrombolytics, but no best practice for catheter salvage has yet been identified. Venous Thrombosis Increasing attention is being paid to the risk of deep vein thrombosis associated with central venous access. Infection prevention practices seek to minimize the risk for the routes of spread. Hematogenous Spread Organisms can be carried hematogenously to the indwelling catheter from remote sources of local infection, such as pneumonia. Hematogenously spread flora from a distant site, such as the urinary tract, are thought of in theory rather than in fact when looking for a source of catheter infection. Due to the rare occurrence of hematogenous seeding of catheters, a catheter is usually not removed in the presence of a bloodstream infection from a well-documented secondary source. Potential pathogens, such as Pseudomonas aeruginosa, enterococci, and Candida, as well as staphylococci, are commonly identified in these cases. Careful hand hygiene, attention to aseptic technique with all infusion-related procedures, minimal manipulation of the central catheter and adjunct administration components, and rigorous disinfection practices when the system must be manipulated represent the core measures for reducing the risk of intraluminal contamination. Extraluminal spread occurs when skin organisms, most commonly coagulase-negative staphylococci and Staphylococcus aureus, incite an infection through portals of entry, including skin and catheter hubs. This is the mostly likely source of an incubating infection for catheters in place for < 14 days.

It is basically a localized form of suppurative (purulent) inflammation, which is associated with pyogenic bacteria and is characterized by edema fluid admixed with neutrophils and necrotic cells (liquefactive necrosis or pus). Other morphologic patterns of inflammation include serous inflammation, fibrinous inflammation, and pseudomembranous inflammation. Fibrinous inflammation is associated with the deposition of fibrin in body cavities, which subsequently stimu lates coagulation. Fibrinous inflammation within the pericardial cavity (fibrinous pericarditis) produces a characteristic bread-and-butter appearance grossly. Serous inflammation produces a thin fluid, such as is present in skin blisters or body cavities. In contrast to fibrinous inflammation, there is not enough fibrinogen present in serous inflammation to form fibrin. Pseudomembranous inflammation refers to the formation of necrotic mem branes on mucosal surfaces. Two infections classically associated with pseudomembrane formation are Clostridium difficile, which produces a characteristic mushroom-shaped pseudomembrane in the colon of peo ple taking broad-spectrum antibiotics, and C. In contrast to an abscess, an ulcer is a defect of epithelium in which the epithelial lining is sloughed and is replaced by inflammatory necrotic material. A localized proliferation of fibroblasts and small blood vessels describes granulation tissue, while an aggregate of two of more activated macrophages refers to a granuloma. The excessive secretion of mucus from a mucosal surface refers to catarrhal (phlegmonous or coryzal) inflamma tion, such as seen with a runny nose. These deficiencies are associated with recurrent thromboembolism in early adult life and recurrent spontaneous abortions in women. The causes of secondary hypercoagulable states are numerous and include severe trauma, burns, disseminated cancer, and pregnancy. Lower risk factors for the development of secondary hypercoagulable states include age, smoking, and obesity. Some patients with high titers of autoantibodies against anionic phospholipids such as cardiolipin (the anti body being called a lupus anticoagulant) have a high frequency of arterial and venous thrombosis. To summarize, it is important to remember that the differential diagnosis of recurrent spontaneous abortions in women includes deficiencies of protein C and protein S, and the presence of the lupus anticoagulant, which is part of the anti-phospholipid syndrome. Also with autosomal dominant inheritance, children with one affected parent have one chance in two of having the disease (50%). Horizontal transmis sion refers to finding the disease in siblings but not parents. That is, with General Pathology Answers 85 autosomal recessive disorders, parents are usually heterozygous and are clinically normal, while symptoms occur in one-fourth of siblings. X-linked patterns of inheritance are seen with disorders involving genes located on the X chromosome. The key point about X-linked disor ders is that there is no male-to-male transmission. Note that in males the terms dominant and recessive do not apply (since they have only one X chromosome). Also note that X-linked inheritance is different from sex influenced autosomal dominant inheritance, an example of which is bald ness. Characteristics of X-linked dominant disorders, which are quite rare, include no skipped generations (dominant inheritance) and no male-to male transmission (x-linked inheritance). Affected females transmit the disease to 50% of their daughters and 50% of their sons. Affected males transmit the disease to all of their daughters and none of their sons. A sub type of X-linked dominant disease is seen when the condition is lethal in utero in hemizygous males. Therefore the condition is seen clinically in heterozygous females, who also have an increase in the number of abor tions. Affected females are rare and may be homozygous for the disease or may have an unfavorable lyonization. These genes are all of maternal origin, possibly because ova have mitochondria within the large amount of cytoplasm while sperm do not. Other examples of mito chondrial inheritance include mitochondrial myopathies, which are char acterized by the presence in muscle of mitochondria having abnormal sizes and shapes. These abnormal mitochondria may result in the histologic appearance of the muscle as ragged red fibers. Electron microscopy reveals the presence within large mitochondria of rectangular crystals that have a parking lot appearance. Some types of sphingolipids are typically found within the central nervous system, and therefore abnormal accumulation of these sub stances produces neurologic signs and symptoms. For example, ganglion cells within the retina, particularly at the periphery of the macula, may become swollen with excess sphingolipids. The affected area of the retina appears pale when viewed through an ophthalmoscope. In contrast, the normal color of the macula, which does not have accumulated substances, appears more red than normal. Autosomal recessive disorders tend to be more common in areas in which inbreeding is more common. An example of this is the increased fre quency of several autosomal recessive genes in Ashkenazi Jews. Ashkenazi denotes an ethnic group, mostly of the Jewish faith, from Eastern Europe. Two storage diseases that have a higher incidence in Ashkenazi Jews are Tay-Sachs dis ease and type I Gaucher disease. General Pathology Answers 87 Patients with Tay-Sachs disease have a deficiency of the subunit. There fore, they have a deficiency of hexosaminidase A, but not hexosaminidase B. Electron microscopy reveals cytoplasmic whorled lamellar bod ies within lysosomes. There are several clinical forms of Tay-Sachs disease, but the most severe is the infantile type. Patients develop mental retarda tion, seizures, motor incoordination, and blindness (amaurosis), and usu ally die by the age of 3 years. Patients may have increased serum levels of acid phosphatase (an enzyme that is typically found in the prostate), erythrocytes, and platelets. Several of these biochemical steps involve transferring methyl groups from folate. This disorder is charac terized by excess uric acid production, which may produce symptoms of gout, mental retardation, spasticity, self-mutilation, and aggressive behavior. The extra X is from the mother in most cases, and therefore this disorder is associated with increased maternal age. The hypogonadism causes decreased testosterone levels, which leads to eunuchoidism, lack of secondary male characteristics, and a female distri bution of hair. Patients are tall due to delayed fusion of the epiphysis from a lack of testosterone. Patients also develop a high voice and gynecomastia, and they have an increased incidence of breast cancer. Patients have small, firm, atrophic testes, histo logic sections of which reveal atrophy, Leydig cell hyperplasia, sclerosis of the tubules, and lack of sperm production. The fragile X syndrome, which is more common in males than females, is one of the most common causes of familial mental retardation. Additional clinical features of this dis order include developmental delay, a long face with a large mandible, large everted ears, and large testicles (macroorchidism). Normally these repeats average up to 50 in number, but in patients with fragile X syndrome there are more than 230 repeats. During oogenesis, but not spermatogenesis, premutations can be converted to mutations by amplification of the triplet repeats. An additional find ing associated with these repeat units is anticipation, which refers to the fact that the disease is worse in subsequent generations. Glomerular lesions are very rare, but a mild tubulointerstitial nephritis is quite common and may result in renal tubular acidosis. In addition to the usual dense, lymphoplasmacytic infiltrate of salivary glands, the lymph nodes may show a pseudolymphomatous appearance. This abnormality results from defective maturation of B lympho cytes beyond the pre-B stage. This maturation defect leads to decreased or absent numbers of plasma cells, and therefore immunoglobulin levels are markedly decreased. Most patients are asymptomatic, but some develop chronic sinopulmonary infections. These individuals have frequent infections that are caused by catalase-positive organisms, such as S. The parathyroid glands are also abnormal, and these individuals develop hypocalcemia and tetany. Wiskott-Aldrich syndrome is also an X-linked recessive disorder, but it is characterized by thrombocytopenia, eczema, and immune deficiency. The immune abnormalities are characterized by progressive loss of T cell func tion and decreased IgM. There are decreased numbers of lymphocytes in the peripheral blood and paracortical (T cell) areas of lymph nodes. Both cellular and humoral immunity are affected, and, because patients fail to produce anti bodies to polysaccharides, they are vulnerable to infections with encapsu lated organisms. First of all, these terms are applied to malignant neoplasms and not to benign neoplasms. Grading of a malignant tumor is based on the his tologic degree of differentiation of the tumor cells and on the number of mitoses that are present. These histologic features are thought to be indica tors of the aggressiveness of the malignant neoplasm. In con trast to grading, the staging of cancers is based on the size of the primary lesion, the presence of lymph node metastases, and the presence of blood borne metastases. Lower stages are smaller, are localized, and have a better prognosis, General Pathology Answers 91 while higher stages are larger, are widespread, and have a worse prognosis. Although there are direct-acting chemical car cinogens, such as the direct-acting alkylating agents that are used in chemotherapy, most organic carcinogens first require conversion to a more reactive compound. Vinyl chloride is metabolized to an epoxide and is associated with angiosarcoma of the liver, not hepatocellu lar carcinoma. Azo dyes, such as butter yellow and scarlet red, are metabo lized to active compounds that have induced hepatocellular cancer in rats, but no human cases have been reported. In the past there has been an increase in bladder cancer in workers in the aniline dye and rubber industries who have been exposed to these compounds. Aflatoxin B1, a natural product of the fungus Aspergillus flavus, is metabolized to an epoxide. The fungus can grow on improperly stored peanuts and grains and is associated with the high incidence of hepatocellular carcinoma in some areas of Africa and the Far East. Bronchogenic carcinomas are associated with the development of many different types of paraneoplastic syndromes. These syndromes are usually associated with the secretion of certain substances by the tumor cells. Hypertrophic osteoarthropathy is a syndrome consisting of periosteal new bone forma tion with or without digital clubbing and joint effusion. It is most com monly found in association with lung carcinoma, but it also occurs with other types of pulmonary disease.
