Additional specific examples of success associated with reductions targeting a particular antibiotic class can also be found in the United States and Canada purchase 25mg lamotrigine with mastercard medications jamaica. For example 100mg lamotrigine fast delivery medications xr, in Quebec buy discount lamotrigine 200 mg on-line treatment notes, eliminating cephalosporin use in broiler chicken eggs led to precipitous declines in cephalosporin-resistant Enterobacteriaceae in both retail chicken meat and humans buy lamotrigine 50mg with visa symptoms vitamin b deficiency, even though human use of antibiotics held constant (Dutil et al. When the chicken industry partially resumed injecting cephalosporin in broiler chicken eggs in 2006–2007, cephalosporin resistance began to increase again in both animals and humans. These experiences are critical to understanding the potential for policy interventions. Radical skeptics who continue to ask for ever-more scientific precision may quibble and point out that in some instances restriction efforts have not reverted resistance rates. Yet, given the complex dynamics of resistance selection and transmission, failure in some interventions is not unexpected, and even slowing or halting an upward climb in resistance should be counted as a success. The fact that national policies of banning growth- promotional and routine prophylactic use of antibiotics have led to reversions in antibiotic resistance rates in people reinforces the argument that feeding antibiotics to animals contributes to the spread of antibiotic resistance to human populations. We may bicker and quibble over what proportion of resistant infections in humans is caused by feeding antibiotics to animals. We may disagree over the extent and severity with which restrictions should be used. We may wish to understand more precisely at the molecular genetic level how bacteria spread from animals to people. But two facts are unassailable: (1) adding antibiotics to animals’ feed and water contributes to the spread of antibiotic-resistant bacteria to human beings; and (2) many parties promote the routine use of antibiotics in livestock specifically because they perceive (possibly incorrectly) that it enables the meat, poultry, and drug industries to maximize production and profits. Thus, a group of people in society are using antibiotics injudiciously to mask inferior management practices for perceived gains in short-term profits, contributing to the spread of antibiotic-resistant bacteria to other people in society. Here are some of the usual justifications proffered by agricultural and pharmaceutical industry spokespersons to prevent even modest restrictions on antibiotic use in livestock production. Livestock will die at alarming rates if we don’t allow antibiotics to be used for growth promotion or routine disease prophylaxis. They have only been exposed to antibiotics at appreciable levels in their feed for less than 0. Clearly they are capable of procreating and expanding their numbers without us feeding them antibiotics. A counterargument may be that modern factory farming houses the animals so closely together, and in such unsanitary conditions, that antibiotics are necessary to keep them from getting sick. The solution then is self-evident: raise the animals in more humane, more sanitary conditions. These countries rely on improved husbandry and nonantibiotic techniques such as vaccines to keep their animals healthy, and they have done so in a way in which profits have been maintained and no economic injury to farmers has been apparent (Netherlands Ministry of Economic Affairs, 2014, 2016). Imagine the reaction of patients and the public if hospitals adopted a similar model for patients and crammed 10 patients into a hospital room to save money, giving them all broad- spectrum antibiotics to try to prevent the infections that would inevitably follow. Similarly, the Netherlands reduced antibiotic use in livestock by 50 percent between 2009 and 2013, while banning use for both growth promotion and disease prevention (Netherlands Ministry of Economic Affairs, 2014, 2016). Their businesses have not suffered from the restriction, nor have farmers’ or consumers’ costs risen significantly. In addition, a growing number of farmers in the United States are successfully raising food animals while using antibiotics only for treating sick animals. California recently took an important step forward by prohibiting the regular use of antibiotics in livestock (whether for growth promotion or disease prevention) starting in 2018 and is also requiring the collection of data on antibiotic use for the first time in the United States, which could further advance the conversation if done 4 well. Do we truly have such little confidence in our American farmers outside of California that we believe they cannot be as successful as Danish or Dutch farmers? Furthermore, as mentioned above, the assumption that routine use of antibiotics substantially enhances economic viability of livestock production may no longer be valid. The public will not tolerate any increase in meat cost associated with withdrawing antibiotics from livestock. Quite to the contrary, the public is increasingly demanding meat from animals raised without antibiotics. Many food companies have begun to respond to this market force by moving toward purchasing meat from antibiotic-free vendors. These very large businesses/purchasers include Chipotle, Chick-fil-A, Costco, McDonalds, and Subway (Robinson et al. Within the last year, chicken companies such as Perdue, Tyson, and Foster Farms have made commitments to eliminate the routine use of medically important antibiotics. In 2012, a Consumer Reports survey found that 86 percent of consumers polled said that meat and poultry raised without antibiotics should be available in their local supermarket; more than 60 percent said they would be willing to pay at least $0. As the public has become more educated and aware of the antibiotic resistance crisis, they are increasingly voting with their wallets. Sales estimates of meat raised without any antibiotics increased 25 percent from 2009 to 2011 (Perrone, 2012). In 2013, sales of organic meat, poultry, and fish were up 11 percent over the prior year, to $675 million (Organic Trade Association, 2014). Ultimately, market forces may well be a significant part of the solution to this societal conundrum in the United States. Furthermore, some of the drugs that are not considered “medically important” are similar in mechanism to antibiotics used in humans and have the substantial potential to trigger cross-resistance (Marshall and Levy, 2011). In addition, the currently used definition of which antibiotics are medically important is incomplete and evolving. One antibiotic that is not considered medically important is bacitracin, but it is used in patients quite commonly, albeit topically rather than systemically. If we lose bacitracin for topical use, we will be forced to use other antibiotics in its place. Therefore, some of the agents that are described as “not medically important” are in fact medically important to physicians. Finally, because many antibiotic resistance mechanisms are genetically linked (physically connected) in genomes or mobile genetic elements, use of one antimicrobial agent can select for resistance to another, even if the agents are unrelated with respect to chemical structure, target, or resistance mechanism (Marshall and Levy, 2011). Thus, exposure to antimicrobial agents that are not used in human medicine has the potential to select for resistance to agents that are used in human medicine. We should not allow this risk to be dismissed categorically by those who have a vested interest in continuing current farming practices. We cannot count on new antibiotics to save us from this crisis—the pipeline is inadequate. We must do a much better job of preserving the effectiveness of the antibiotics we have now. Because nearly 80 percent of antimicrobial use in the United States is in livestock, we must do a much better job of reducing antibiotic use in livestock as well as in humans. It is important that we not be bogged down or distracted by quibbles over the minutiae of the molecular mechanisms by which antibiotic resistance spreads from animals to humans or the precise proportion of antibiotic-resistant infections in humans that is caused by antibiotic use in animals. The fundamental point is that antibiotic-resistant microbes can move from livestock fed antibiotics to humans, that patients are harmed as a result of this process, and that, in some countries, national policies eliminating growth promotion and routine prophylactic use have reverted or slowed antibiotic resistance rates. Thus, from a policy perspective, the real question is, what is the “pro” of antimicrobial use in animals that might cause society to agree to take on the corresponding “con”—the risk of harming humans by this use? The pro is the ability of industrial farms to take shortcuts in animal husbandry to increase the potential for profit. Do we, as a society, believe that livestock producers should be afforded the right to profligate antimicrobial use by growing animals in unsanitary and crowded conditions despite the clear associated risk of transmission of antibiotic-resistant bacteria from animals to humans, resulting in harm to humans? If we reduce the amount of antibiotics fed to animals by 50 percent per animal, but we grow twice as many animals, we still will be exposing the bacteria in the food production environment to the same amount of antibiotics, driving antibiotic resistance.
She was uncomfortable being examined and undergoing tests and best 50mg lamotrigine medicine on time, to some extent lamotrigine 25 mg visa medications 25 mg 50 mg, was afraid she might find out she had a problem that she didn’t know she had generic 100 mg lamotrigine amex rust treatment. She wasn’t sure why she didn’t like hospitals cheap 50 mg lamotrigine fast delivery treatment ibs, but she avoided them at all costs, even if it meant not visiting friends and relatives in the hospital. Now, at age fifty-five, Ella had become increasingly con- cerned about her phobia. She was at an age when it seemed more important than ever to have regular medical checkups. Also, her parents were older, and she worried that they might soon need to spend time in a hospital and thatshewouldn’tbeabletovisitthem. Shefinally decided to seek treatment when her husband was sched- uled to have his hip replaced. Ella’s treatment began with developing two hierar- chies—one for doctor visits and the other for hospitals. The hierarchy took into account the variables confronting your fear 95 that contributed to her fear, including the sex of the doc- tor (female doctors were easier than males), the age of the doctor (doctors younger than forty and older than sixty made her more anxious), the type of procedure being done (she was most nervous about procedures used to detect cancer, such as a mammogram), and the type of doctor (family doctors were easier than specialists). The hospital hierarchy included items ranging in difficulty from relatively easy (for example, spending time in the lobby or cafeteria of a hospital) to more difficult (for example, walking through the halls in the emergency room or visiting someone in a hospital room). She made appointments for physical exams three times per week over a two-week period. The next four exams were with other doctors (recommended by her family doctor), starting with female physicians and working up to male physicians. Ella also arranged to have a number of tests done, including blood work, a mammogram, and a colonoscopy. Over the course of these two weeks, her fear of doctors decreased to a mod- erate level. Ella decided to continue her exposure prac- tices with doctors about once per week over the next month while also starting to confront her fear of hospitals. During the next few weeks, Ella made a point of vis- iting hospitals about four times per week for an hour or two, usually on her way home from work. She visited the hospital where her husband was scheduled to have his 96 overcoming medical phobias surgery, as well as several others. She began with the eas- ier items on her hierarchy (for example, visiting her fam- ily doctor, who was a woman in her early fifties) and worked her way up to the more difficult items (for exam- ple, seeing a young male dermatology resident for a spe- cialist appointment). Eventually, she had practiced all of the items on her hierarchy except for visiting a loved one in the hospital; at the time, she had no friends or rela- tives who were hospital patients. However, when her hus- band had his surgery, she was able to visit him daily with only minimal anxiety. It requires time and patience, as well as a willingness to feel uncomfortable, at least temporarily. Unlike some of the other exercises in this book, this is not an exercise you can complete in a few minutes. Instead, you’ll need to practice for several hours over the course of a few days or a few weeks to complete this exercise. If you have a history of fainting upon encountering blood, needles, or related situations, don’t complete this exercise until you have read chapter 6. For those who faint or even just feel faint, we recommend only confronting your fear 97 completing this exercise in conjunction with the applied tension techniques described in chapter 6. Essentially, this exercise involves exposing yourself to the situations on your hierarchy, using the strategies described in this chapter along with those in chapters 3 and 4. Remember, your exposures should be planned, structured, predictable, frequent (at least several times per week), and prolonged (ideally lasting until your fear has decreased to a mild or moderate level). The case examples in this chapter illustrate how you might orga- nize your own exposure practices. Each time you complete an exposure practice, record in your journal how anxious you were before beginning the practice, your anxiety level every five or ten minutes during the practice, and your anxiety level at the end. In addition, record what practice you completed (for example, “watching a cardiac surgery video for thirty minutes”), how long it took for your dis- comfort to decrease, and any other relevant details (for example, whether you fainted during the practice). Here are 98 overcoming medical phobias some strategies for dealing with four of the most common obstacles. You may be busy with work, school, raising children, or any number of other activities, making it difficult to find an hour or two to devote to exposure on a given day. If so, we recommend that you schedule your exposure practices just as you would any other activity or appoint- ment in your day. If it’s too difficult to prac- tice during the week, increase the amount of practice you do on the weekend. Fortunately, exposure-based treatments tend to work quickly for phobias of blood, needles, doctors, and dentists. Following a few hours of exposure, you will likely notice a reduction in your fear. If you can’t complete a specific exercise, ask yourself, “How can I change this exercise to make it more manageable? Specifically, some people have small veins that are hard to find, making it difficult to take blood. As a result, nurses, doctors, and others often try unsuccessfully to take blood from various locations and may end up causing considerable pain and bruising with each attempt. If you have small veins, you should take steps to minimize the “trauma” that normally occurs when you have blood taken. First, make sure that the person drawing your blood is experienced in drawing blood from people with small veins. Second, let the person know that it’s generally very difficult to draw your blood from the usual places. If there’s another location that tends to work better (for example, your hand), suggest that the person drawing your blood try that location first. If your fear is staying high, make sure you have given it an adequate opportunity to come down. Another factor that may pre- vent your fear from decreasing is significant life stress (for example, a hectic work schedule, frequent marital con- flict, or parenting pressures). If you’ve had a stressful day 100 overcoming medical phobias and your fear doesn’t decrease during practice, try again another day. Finally, it’s best not to engage in safety behaviors or subtle avoidance behaviors, such as distrac- tion, during your exposures. These behaviors may keep your anxiety higher over the course of your exposure practice. For people who faint, exposure should be combined with applied muscle tension exercises, which are described in chapter 6. This chapter included four case examples to illustrate how exposure therapy plays out in real life, and we also presented strategies for dealing with some of the most common obstacles that may arise during treatment. As mentioned earlier, a lit- tle more than 50 percent of people with needle phobias have a history of fainting during injections and almost 70 percent of people with blood phobias report fainting upon exposure to blood (Öst 1992). The tendency of these pho- bias to be associated with fainting is unique; it is very unusual for people with other types of phobias (for exam- ple, fears of heights, animals, or flying) to report fainting in the feared situation. If you tend to faint in your feared situations, practic- ing exposures can be especially challenging. We’ll also teach you a proven technique to help reduce 102 overcoming medical phobias the possibility of fainting. One is the cardiovascular system, which includes the heart and blood vessels, and the other is the nervous system, which includes the brain, the spinal cord, and all of the nerves that control the muscles and organs. Because the brain is above the heart when we are standing upright, gravity tends to pull blood away from the brain.
Registries are most successful in improving care delivery when they are augmented by client management software that generates automatic reminders and other follow-up discount 100 mg lamotrigine visa medicine measurements. The use of registries and reminders to maintain surveillance of patients with hypertension generic lamotrigine 100 mg amex pretreatment, for example lamotrigine 25mg online treatment table, has consistently been shown to 17 improve care for clients with high blood pressure order lamotrigine 25 mg free shipping medications grapefruit interacts with. As many clients with chronic 27 disease suffer from co-morbid conditions, information systems must be capable of linking data across different disease registries. Practice teams can also use registries to map their client population’s health needs and set service priorities in the practice. If their registry showed that most of their clients smoked, for example, a practice team might increase smoking cessation counseling during visits, or increase referrals to community cessation classes. Although registries need not be electronic, well designed electronic registries are easiest to use. Registries can play an important role in identifying unmet local health needs and underserved populations. Comparing clients’ characteristics recorded in the registry and population level socio-demographic and health status data, for example, can reveal populations at high risk or who are not accessing care. Client registries are most useful to population level prevention/promotion when they record clients’ socio-demographic and lifestyle risk factors. Provider Portals Information systems need to be fully integrated to ensure client information is accessible to all members of the practice team in order to support case management and care coordination; and to improve decisions about preventative care, diagnosis and treatment. Information systems within clinical practices and within the community need to be linked effectively to tertiary care centres and other external health care services that provide acute, primary, rehabilitation, long-term, and palliative care. Such links assure clients continuity of care, help in care planning and follow-up, and enable practice teams (and community providers) to direct clients to the services they need, while at the same time avoiding duplicate procedures. Provider portals at all care sites that access client data are necessary so that all 28 providers have the same information about the client’s care in real time. This will require establishing data standards that all software vendors must adopt if their products are to be used across the health care environment. Information systems employed in various telehealth initiatives use technology to link providers and individuals in remote locations, link providers to one another, decision support resources, specialist care and to community resources. Many jurisdictions now give consumers access to their personal health records, lab data, prescriptions, and prevention and treatment plans. Two way portals let clients book visits and let providers book check-ups and tests with patients as well as provide reminders for self-management follow-up, immunization and screening. Some client portals provide access to information on best practices guidelines, community resources, educational tools and reference materials to support self-management. Population Health Data Effective outreach to underserved populations, and rational allocation of health and social resources within a region or other geographical area, requires information systems that capture data on the population, and integrate it with clinical and other client information systems. Population health data includes demographic and health status data such as: rates of chronic diseases; data on lifestyle risk factors such as smoking, physical activity and fruit and vegetable consumption; data on environmental health risks, such as air, water, and soil quality; and social and economic trends such as literacy, employment rates, income, and housing status. Neither clinical practices nor community providers can be expected to generate all this data, but both should have the capacity to use it to set priorities and shape programs. The system developed in Saskatchewan’s Saskatoon Regional Health Authority is an exemplar of a population health data system developed collaboratively, and used collaboratively, by local health and social service organizations to improve the health of, and reduce health inequalities among, the population in the region. It refers to the development and implementation of policies aimed at improving individual and population health and to address inequities among groups within the general population. Public policy refers to legislation, regulation, administrative and organizational policies. Healthy public policies created to prevent chronic diseases Healthy Public Policy often focus on individual behaviours such as smoking, • Legislation and regulations unhealthy diet, lack of physical • Fiscal policies activity and alcohol and drug • Guidelines use. These policies include, for • Organizational policies and programs example, smoking bans, healthy menus in school cafeterias, workplace fitness facilities, improved food labeling and zoning by-laws to create bike lanes. However, preventing chronic disease through healthy public policy also requires a focus on the social determinants of health. There is considerable evidence that this broader focus can reduce inequalities in chronic disease among different population groups, and reduce the overall incidence of chronic disease in population groups with low socio-economic status. Developing and promoting healthy public policies is a shared responsibility of individuals, communities, the private sector and governments. Implicit in this is the recognition that the health status of individuals and population groups are due to factors and conditions that extend beyond the health care system. The responsibility crosses many sectors: health, education, labour, social services, housing, transportation, recreation and the justice system. To deal effectively with chronic disease, health care organizations and community organizations need to work together to understand the key determinants affecting the health of their population and advocate for healthy public policies. Legislation and regulations Legislation and regulations have been proven to be effective tools. For example, legislation to reduce smoking rates was found to be more effective than 45 individual-level interventions such as physician counseling. Legislation and regulations, including by-laws that prohibit smoking in public places, that provide good facilities, such as bike lanes and green spaces, and provide affordable 30 housing and transportation have helped reduce threats to health, improve living 46 conditions, and encourage healthier behaviours. Fiscal policies Fiscal policies are an effective tool to reduce social inequities and remove economic barriers to healthier choices. Findings indicate that policies that led to changing the economics of food choices in schools and other environments can 47 have positive effects on healthy eating. Financial incentives can be used to encourage the use of public transit, to encourage the private sector to reduce pollution, to increase participation in sports and recreational activities and to persuade tobacco farmers to switch to other crops. Economic interventions such as reducing the price of whole wheat flour and lowering duty on imported fruits can make healthy eating more accessible. Financial disincentives can be created to make it more costly to partake in unhealthy behaviours, such as raising taxes on cigarettes, junk food or driving fuel-inefficient automobiles. Guidelines Guidelines that encourage healthier choices help to set the standards for healthy living. Examples of these guidelines include the Canada Food Guide, Canada’s Physical Activity Guide and low-risk drinking guidelines. Easy to use tools and programs, such as the ‘5 to 10 a day’ vegetables and fruits campaign and ‘activ8’ to promote physical activity in schools that are based on guidelines, support individuals and families to make consistently healthier choices. The translation of the Canada Food Guide into several languages, as well as ensuring that it is culturally appropriate, is an example of how guidelines can also reduce inequities in access to new immigrants. Organizational policies and programs Organizations can develop policies and programs to support individuals and families in their efforts to maintain their health. Examples of this include workplaces that offer fitness programs, car pooling, flexible hours, elder care leaves and Employee Assistance Programs. Private sector policies that lead to supermarkets and other services being available in lower income neighborhoods, as well as community policies and programs such as day care, at-risk youth outreach, employment retraining, immigration and re-settlement initiatives, all promote health and the reduction of inequalities. The creation of healthy public policy requires cooperation and support among a diversity of stakeholders. Individuals, communities, institutions and organizations can be expected to lead or to be full participants in the development of most healthy public policies. For example, a coalition of over 25 agencies serving homeless young parents in downtown Toronto were effective in securing funding for the development of social housing for their clients. The health care sector can play an important role in fostering healthy public policies that help reduce chronic diseases and enable clients to self-manage chronic conditions. It can do so in several ways: by implementing policies within the sector that ensure genuinely equal access to universal health services; by taking a lead role in advocating for public policies with clear links to risks for chronic diseases, such as anti-smoking bylaws and healthy school nutrition policies; and by lending its support to public policy initiatives to address the broader determinants of health such as income, education, working conditions and social and physical environments. It can also provide community groups, individuals and health care workers with information needed for effective advocacy for healthy public policy such as population level data on health status and socio-economic inequities, understanding of the determinants of health, and understanding of the links between existing policies and health outcomes.

Within a decade of its development, 9 methicillin resistance to Staphylococcus aureus emerged. Most of the resistance was secondary to production of beta-lactamase enzymes or intrinsic resistance with alterations in penicillin-binding proteins. Staphylococcus aureus is the most frequent cause of nosocomial pneumonia and surgical- wound infections and the second most common cause of nosocomial bloodstream 12 infections. Other risk factors include intravascular catheters, tracheostomy, gastrostomy, indwelling urinary catheters and decubitus ulcers. Another important consideration is careful evaluation of culture and sensitivity reports. Infection is often confused with colonization and can lead to unnecessary utilization of antimicrobial agents. Potential anatomical sites of colonization include the anterior nares, axillae, upper extremities, urinary tract and perineum. Consultation with an infectious-disease specialist is advised regarding management when there is question as to infection versus colonization. However, some strains remain sensitive to minocycline and recently, strains acquired outside of health-care settings remain susceptible to agents, such as clindamycin and gentamicin. Clindamycin, co-trimoxazole, fluoroquinolones or minocycline may be useful when patients do not have life-threatening infections caused by strains susceptible to these agents. For serious infections caused by strains that are susceptible to rifampin, adding this agent to vancomycin or fluoroquinolone may contribute to improved outcomes. The infecting strain always should 17 be tested for susceptibility prior to initiating any of these therapies. Enterococci are generally not particularly pathogenic in humans and have traditionally been classified as relatively harmless commensals. Enterococci alone rarely colonize or cause infection of the respiratory tract or cause primary cellulitis, unlike other gram-positive organisms such as Staphylococcus 19 aureus. Though over a dozen different species of enterococci have been identified, two species, Enterococcus faecalis and Enterococcus faecium, are the most prevalent in human infections. Enterococcus faecalis, which comprises 85%-90% of all human enterococcal infections, is typically considered the most pathogenic. The remaining 5%-10% of enterococcal infections are due to Enterococcus faecium, which is increasingly resistant 19 to vancomycin and is now considered a major nosocomial pathogen. Enterococci typically are associated with causing urinary tract infections, intra-abdominal and pelvic sepsis, surgical wound infections and bacteremia, in descending order of frequency. However, they now are emerging as highly-resistant 19 organisms and nosocomial pathogens. Enterococci have been identified as the third most common cause of nosocomial, 20 hospital-acquired pneumonia. Enterococci are intrinsically resistant to a number of antibiotics and antibiotic classes. They do not possess exotoxins or enzymes that allow invasion and destruction of tissues. They can, however, readily acquire resistance genes that are capable of transfer to other bacteria. Resistant enterococcus can be isolated from patients who have been institutionalized for long periods of time. Other risk factors for acquiring a resistant enterococcal infection include severity of underlying illness, presence of invasive devices, prolonged antibiotic use and prior colonization. Those at higher risk include immunosuppressed hosts such as renal dialysis, transplant and oncology patients. Treatment of serious infections due to beta-lactam resistant gram-positive organisms. Treatment of serious infections due to gram-positive organisms in patients with serious beta-lactam allergies. Prophylaxis for endocarditis for certain procedures based on American Heart Association recommendations. Routine surgical prophylaxis unless the patient has a severe allergy to beta- lactam antibiotics. Treatment of one positive blood culture for coagulase-negative staphylococcus if other blood cultures drawn at the same time are negative (i. Continued empiric use in patients whose cultures are negative for beta-lactam resistant gram-positive organisms. Prophylaxis for infection or colonization of indwelling central or peripheral intravenous catheters. Routine prophylaxis for patients on continuous ambulatory peritoneal dialysis or hemodialysis. Treatment of infection due to beta-lactam sensitive gram-positive microorganisms in patients with renal failure (for ease of dosing schedule). Enterococcus has developed intrinsic resistance to many antibiotics, including cephalosporin antibiotics. They exhibit low-level resistance to aminoglycosides, which can be overcome by adding a cell-wall active agent such as ampicillin or vancomycin. These combinations can provide a bactericidal effect, sometimes referred to as a synergistic effect. Resistance to beta-lactams occurs secondary to either enzyme production or altered penicillin-binding proteins. Beta-lactamase producing strains for Enterococcus faecalis, which are typically rare, can be treated with ampicillin/sulbactam + an aminoglycoside. Enterococcus faecium, which produce an enzyme different from penicillinase that is not inhibited by penicillin, are now commonly resistant to many beta-lactams although there are reports of success with combination 20, 26 therapy using double and or triple combination regimens. Enterococci develop 19, 27 resistance via three phenotypes, which are outlined in Table 2. Steps may include: • A comprehensive antimicrobial utilization plan that includes education of all staff (medical, nursing and other ancillary services). A comprehensive group of individuals, which may consist of infection control, infectious disease, medical, surgical, nursing, microbiology, pharmacy, epidemiology, quality assurance, administration staff and all other pertinent entities, should develop its own protocols for each individual institution. For line-related bacteremia, simply removing the intravenous device may be sufficient. Surgical debridement and drainage may be adequate for cases of soft tissue infections, surgical site infections and abscesses.
