Microbiological Contamination Risk Prevention in Infusion Therapy sionth www.safeinfu erapy.com Microbiological Contamination Definition Definition: Microbiological contamination Microbiological contamination refers to the nonintended or accidental introduction of infectious material like bacteria, yeast, mould, fungi, virus, prions, protozoa or their toxins and by-products [1, 2]. “A nosocomial infection — also called “hospital-acquired infection” is defined as: An infection occurring in a patient in a hospital or other healthcare facility in whom the infection was not present or incubating at the time of admission. This includes infections acquired in the hospital but appearing after discharge, and also occupational infections among staff of the facility.” [3] Types of microbiological pathogens There is a broad range of microbiological pathogens, which can cause contamination and thus infections. Within these groups, several different types of pathogens exist: 1.Bacteria: are microorganisms with a size of up to 5 μm and re- present the most important group of pathogens when discussing microbiological contamination. According to the constitution of their cell wall, bacteria can be distinguished into Gram-positive and Gram-negative bacteria (see Figure 2, MeningococcusBacteria). Bacteria can be further distinguished as follows: 1.1 “Commensal” bacteria: belong to the normal flora of healthy humans. They are usually harmless to healthy people or even have a significant protective role by preventing colonization by pathogenic microorganisms. Some commensal bacteria may however cause infection, if the natural host is compro- mised or if they are brought into the host’s tissue. 1.2 Pathogenic bacteria: have greater virulence and cause infections regardless of the host’s status. 2.Viruses: subcellular biological objects with a size of 20-200 nm. They exist with and without envelopes (shells mostly derived from host membranes covering the virus) and can cause serious infections (see Figure 3, HI-Virus). 3. Prions: infectious protein particles. They are the smallest pathogens, which are below 5 nm in size. Both prions and viruses are particles without own metabolism and are thus not regarded as living organisms. For reproduction, they depend on the metabolism of a host organism. 4. Fungi, yeasts and protozoa with up to 200 μm in diameter are three further groups of infection sources [3]. A Mycelium, the vegetative part of a fungus, is shown in Figure 4, Penicillium digitatum. 2 Toxic by-products of microorganisms Endotoxin: The most common example for endotoxins are the lipopolysaccharides (LPS) found in the outer membrane of the group of Gram-negative bacteria. If this membrane degenerates, e.g. when the bacteria dies, LPS’s are released. LPS are heat stable and cause serious fever, chills, sepsis and irreversible shock. Exotoxin: Exotoxins are toxic substances, which are actively excreted or released by a microorganism, like bacteria, fungi, algae, and protozoa. They can cause major damage to the host by destroying cells or disrupting normal metabolism, but they are mostly destroyed by heat. For example, Clostridium tetani produces the tetanospasmin which leads to the symptoms of tetanus; Vibrio cholerae produces the choleratoxin and leads to the symptoms of cholera. Under normal circumstances, one single bacterium will not cause any harm. However, even one bacterium can quickly replicate itself into millions: Under optimal conditions, bacteria like Escherischia coli can double their population every 20 minutes. Time Quantity of Escherichea coli 20 min. 2 40 min. 4 1h 8 2h 64 3h 512 4h 4.096 5h 32.768 6h 262.144 6 h 40 min. 1.048.576 It is also important to know that several pathogens can survive under extreme environments, e.g. Hepatitis C virus is still infectious after 7 days on dry surfaces [4].

They are important contributors to morbidity and mortality. They will become even more important as a public health problem with increasing economic and human impact because of: Increasing numbers and crowding of people n More frequent impaired immunity (age, illness and treatments) n New microorganims n Increased bacterial resistance to antibiotics” [5] n Microbiological contamination is most dangerous for patients when it affects parenteral therapy and the intravenous catheters used. In this case, pathogens can directly reach the systemic circulation and cause catheter-related blood stream infection (CR-BSI) or travel to various organs and induce organ failure. Therefore, prevention of CR-BSI is crucial. In the mid-90s the Centers for Disease Control and Prevention (CDC) published a standard definition for CR-BSI, which is the most widely accepted definition for CR-BSI [6]. Bacterial infections can mostly be treated with antibiotic drugs. However, there are cases where this is extremely difficult or even impossible because the bacteria have become multidrug resistant. Against most viruses and all prion diseases, there are also no effective drugs available. Thus, prevention of such infections is crucial. Definition of Catheter-Related Blood Stream Infection (CR-BSI) The definition of CR-BSI helps with the decision whether a catheter is the primary source of bacteremia in a patient. They include exit site or tunnel infections and are defined as: nErythema or induration within 2 cm of the catheter exit site, in the absence of concomitant bloodstream infection and without concomitant purulence n For tunnel infections, presence of tenderness, erythema, or site induration >2 cm from the catheter site along the subcutaneous tract of a tunneled catheter in the absence of concomitant blood stream infection is required [7]. Legend no data <1% 1-5% 5 - 10 % 10 - 25 % 25 - 50 % > 50 % Fig. 4: Prevalence of MRSA in Europe 2008 [7] 4 Incidence and Prevalence of MRSA Methicillin resistant Staphylococcus aureus (MRSA) infection is a serious worldwide health concern. MRSA is defined as any strain of Staphylococcus aureus that has developed resistance to beta-lactam antibiotics which include the penicillins (methicillin, dicloxacillin, nafcillin, oxacillin, etc.) and the cephalosporins. According to the Centers for Disease Control and Prevention (CDC), MRSA currently causes about 1 % of all staphylococcus infections and more than 50 % of health-care associated staphylococcus infections. After Staphylococcus epidermidis, Staphylococcus aureus is the second most common pathogen causing health care-associated infections in the United States, and 49 % of those infections are caused by the highly antibiotic resistant bacteria MRSA. A strain called USA100 is the most common type of MRSA involved in health care-associated infections in U.S. hospitals [8]. MRSA is especially troublesome in hospitals and nursing homes where patients with open wounds, invasive devices and weakened immune systems are at greater risk of infection than the general public. Each year in the United States, more than 290,000 hospitalized patients are infected with Staphylococcus aureus. Of these staphylococcal infections, approximately 126,000 are related to MRSA [9]. Definition of multidrug resistant bacteria Multidrug resistance is a condition enabling a disease-causing organism to resist distinct drugs or chemicals of a wide variety of structure and function targeted at eradicating the organism [10]. Important multidrug resistant organisms are n Methicillin resistant Staphylococcus aureus (MRSA) n Vancomycin resistant Enterococci (VRE) n Extended spectrum ß-lactamase (ESBLs) producing Gram-negative bacteria n Klebsiella pneumoniae carbapenemase (KPC) producing Gram-negatives n Imipenem resistant Acinetobacter baumannii n Imipenem resistant Pseudomonas aerginosa n Multidrug resistant Mycobacterium tuberculosis (MDR-TB) and extremely drug resistant Mycobacterium tuberculosis (XDR-TB) 5 Microbiological Contamination Causes How does contamination occur? Contamination may occur if pathogens are carried unintendedly from a source to an orifice or an artificial body opening of the host where they then start growing and exerting their harm. There are several possible sources, entry routes and ways for transmission. n Sources: Natural body orifices or artificial openings due to injury or disease n Entry portals: Natural body orifices or artificial openings due to injury or disease n Direct transmission via contact or droplet spread n Indirect transmission via surfaces or instruments n Indirect transmission via vectors, mosquitoes, flies, rats transmitting the infection n Indirect transmission via intermediate host [e.g. human, animal or insect, e.g. transmission of malaria through mosquitoes]. In a health care setting, important ways of contamination are hands of health care personnel and via droplets in the air. Causes Generally speaking, contamination occurs if any part of a system, product or medicine gets in touch with microbiological pathogens where it should be sterile. For example, if a surgical instrument is contaminated with pathogens, the result might be a surgical wound infection. Typical pathogens of such infections are shown below. Contamination in infusion settings may occur, when pathogens are carried inside of the infusion system, mostly happening during manipulation (see Figures 7, 8). With regards to infusion-related infections, there are two separate routes: the extra- and the intraluminal route [12]. Intraluminal contamination is the consequence of improper handling of the infusion system, e.g. of the catheter hub at the time of connection and disconnection of the administration set. It is the most common origin of catheter infections after the first week of catheter placement [13, 14]. Extraluminal catheter seeding results from bacterial invasion from the catheter entry site along the external surface of the catheter and leads to bacteremia most often during the week following catheter placement [15, 16].

Infections acquired in health care settings are among the major causes of death and increased morbidity among hospitalized patients. They are a significant burden both for the patient and for public health. A prevalence survey conducted under the auspices of WHO in 55 hospitals of 14 countries representing 4 WHO Regions (Europe, Eastern Mediterranean, South-East Asia and Western Pacific) showed an average of 8.7 % of hospital patients had nosocomial infections. At any time, over 1.4 million people worldwide suffer from infectious complications acquired in hospital [18]. The highest frequencies of nosocomial infections were reported from hospitals in the Eastern Mediterranean and South-East Asia Regions (11.8 and 10.0 % respectively), with a prevalence of 7.7 and 9.0 % respectively in the European and Western Pacific Regions [19]. The most frequent nosocomial infections are infections of surgical wounds, urinary tract infections and lower respiratory tract infections. Fig. 9: Local infection at catheter entry site 8 The WHO study, and others, have also shown that the highest prevalence of nosocomial infections occurs in intensive care units and in acute surgical and orthopaedic wards. Infection rates are higher among patients with increased susceptibility because of old age, underlying disease, or chemotherapy [3]. Contamination and subsequent infection can occur locally or systemically. n In case of a local infection, surgical wound infections, skin irrit- ations and catheter entry site infections may occur. n In case of a systemical inflammation with pathogens reaching the systemic circulation, septicemia, sepsis and septic shock may be the result, as well as pathogens might be transported to organs or extremities and cause organ infection and failure as well as endocarditis or osteomyelitis which might possible result in amputation [20, 21]. Fig. 10: Ecchymosis, cutaneous manifestation of sepsis Fig. 11: Septic shock In all cases, additional diagnostic investigation and treatment will be necessary, leading to discomfort, emotional stress for the patient and potential side effects and pain. In some cases, they might even lead to disabling conditions that reduce the quality of life. Along with this, the hospital stay might be prolonged. One study [12] showed that the overall increase in the duration of hospitalization for patients with surgical wound infections was 8.2 days, ranging from 3 days for gynaecology to 9.9 days for general surgery and 19.8 days for orthopaedic surgery. In ICU patients, MRSA infection is therefore independently associated with an almost 50 % higher likelihood of hospital death compared with MSSA infection [22]. Others have found the mortality rate for blood-stream-infections to be 10-25 %, that of septic shock was even higher with 40-60 % [23]. Thus, nosocomial infections are one of the leading causes of death [24]. The EPIC II point-prevalence study of infection in critically ill patients performed on 8th May 2007 assessed the role of methicillin resistance in survival of patients with Staphylococcus aureus infection. On the study day, 7,087 (51 %) of the 13,796 patients were classified as infected. There were 494 patients with MRSA infections and 505 patients with MSSA (Methicillin-susceptible Staphylococcus aureus) infections. ICU mortality rates were 29.1 % and 20.5 %, respectively (P<0.01) and corresponding hospital mortality rates were 36.4 % and 27.0 % (P<0.01). Multivariate analysis of hospital mortality for MRSA infection showed an adjusted OR* of 1.46 (95 % CI 1.03-2.06) (P=0.03). *Odds Ratio 9 Microbiological Contamination Consequences Economical consequences Impact of nosocomial infections Uslusoy et al. [17] have estimated more than two million cases of nosocomial infections every year (5.7 infections per 100 admissions) with an average cost of $ 13,973. They state that in case of MRSA this can be up to € 35,367. Nosocomial infections occur in more than two million hospitalizations each year [25]. The economic costs of nosocomial infections are considerable [26, 16]. The increased length of stay for infected patients is the greatest contributor to cost [6, 27, 13]. Additionally, increased morbidity and increased total cost per patient who survived is approximately $ 40,000 [27, 28]. In their study evaluating the outcome of intravenous catheter related infections in critically ill patients, Rello et al. [29] found that among the survivors, the hospital stay was increased by 19.6 days. This added cost of € 3,124 per episode of catheter related infection based on the additional days only, not taking diagnostic and treatment expenses into account. Vandijck et al. [30] investigated the daily cost of antimicrobial therapy in patients with ICU-aquired bloodstream infection. The mean overall daily antimicrobial cost was € 114.25 per patient. As the average duration of antimicrobial therapy for infected patients ranges from 7 to 14 days, the total cost of antimicrobial therapy per patient ranged between € 800 & € 1,200. In special cases of infections from bacteria resistant to comon antibiotics, it has been identified a potential extra cost of $ 8,480/patient (approx. € 5,000) [31]. 10 A systematic literature review covering 1990-2000 calculated the following average attributable costs (costs calculated with a control group of patients and including only costs directly resultant from nosocomial infestion) to the hospital for nosocomial infections (see Figure 12): Average nosocomial infection, mean cost = $ 13,973 Bloodstream infection, mean cost = $ 36,441 n Methicillin resistant Staphylococcus aureus infections (MSRA), mean cost = $ 35,367 n Surgical site infection, mean cost = $ 25,546 n Pneumonia, mean cost = $ 9,969 n n For the following infections, no studies were done to determine attributable costs but treatment costs are known (see Figure 13): Urinary tract infection, mean cost = $ 1,008 Varicella zoster virus, mean cost = $ 27,377 n Tuberculosis, mean cost = $ 61,446 n Measles, mean cost = $ 41,087 n n Since the literature review, Roberts et al. [33] created an economic model based upon a sample of patients at Rush University Hospital that controlled for severity of illness and intensive care unit to calculate the average attributable cost of an average nosocomial infection at $ 15,275 [28]. Another recent study utilized national data and a case-control matching method to control DRG, sex, race, age, and comorbidity to calculate that the average excess costs attributable to the national indicator “selected infection due to medical care” are $ 38,656 [29]. Hospital-acquired infections add to the imbalance between resource allocation for primary and secondary health care by diverting scarce funds to the management of potentially preventable conditions. On October 1st 2008, the Centers for Medicare and Medicaid Services (CMS) decided to cease paying hospitals for some of the care made necessary by “preventable complications” — conditions that result from medical errors or improper care and that can reasonably be expected to be averted [35]. The costs of a nosocomial infection outbreak can easily reach millions of dollars [34]. 40 30 20 10 Costs in thsd. $ Costs in thsd. $ Prolonged stay not only increases direct costs to patients or payers but also indirect costs due to lost work. The need for isolation and the use of additional laboratory and other diagnostic studies also contributes to the costs. 70 60 50 40 30 20 10 0 Average nosocomial infection Bloodstream infection Methicillin resistant Staphylococcus aureus infections (MSRA) Surgical site infection Pneumonia Fig. 12: Costs caused by infections, proven by studies 0 Urinary tract infection Varicella zoster virus Tuberculosis Measles Fig. 13: Costs caused by infections, not proven 11 Microbiological Contamination Consequences Risk related Costs for the Healthcare Institution Even non-fatal episodes of microbiological contamination lead to additional involvement for diagnostic (e.g. blood cultures, laboratory work, X-ray) and therapeutic interventions (e.g. antibiotics, catecholamines) as well as an increased length of stay and the average daily cost [36, 37, 38] of the expected clinical treatment. The table below shows the results of such a calculation for selected examples of complications. Patients with severe infections and sepsis are generally treated in intensive care units (ICUs) where close supervision and intensive care treatment by a competent team with adequate equipment can be provided. Staffing costs represent from 40 % to > 60 % of the total ICU budget. Because of the high proportion of fixed costs in ICU treatment, the total cost of ICU care is mainly dependent on the length of ICU stay (ICU-LOS). The average total cost per ICU day is estimated at approximately € 1,200 for countries with a highly developed healthcare system (based on various studies conducted between 1989 and 2001 and converted at 2003 currency rates). Those patients require a prolonged ICU-LOS, resulting in higher costs of treatment compared with other ICU patients. US costof-illness studies focusing on direct costs per sepsis patient have yielded estimates of € 34,000, whereas European studies have given lower cost estimates, ranging from € 23,000 to € 29,000. Direct costs, however, make up only about 20–30 % of the cost of illness of severe sepsis. Indirect costs associated with severe sepsis account for 70–80 % of costs and arise mainly from productivity losses due to mortality [39].

In the case of severe sepsis, which requires full ICU treatment, a hospital may save up to € 56,670 per single case.

Fig. 16: Hands disinfection – disinfection fluid. Prevention of microbiological contamination and thus nosocomial infection has gained increasing importance and attention throughout the last years because of the dramatic consequences for health and economy. Medical societies, hospitals and government agencies have invested in development of evidence based guidelines for prevention of nosocomial infections [3, 6, 10, 11, 41, 42, 49]. Education and training Proper education of health care workers with requisite knowledge, skills and attitudes for good infection control practices is the most important measure for infection prevention. Awareness programmes, in-service education and on-the-job training with periodic re-training or orientation of staff should be provided [41, 42]. Among all measures, hand hygiene has the biggest impact in infection prevention and gloves as well as other personal safety equipment should always be used (see Figure 15, 16). The WHO and CDC have launched a campaign named “Wash your hands”, along with posters, trainings, websites and guidelines on hand hygiene [43, 44, 45, 46]. Proper hand hygiene cuts MRSA rates by 50 % [47]. It is important to stress that use of gloves does not obviate the need for hand hygiene [6]. 16 Fig. 17: Using sterile disposables. Fig. 18: Routine replacement of IV administration sets according to CDC or local hospital / institutional guideline. Monitoring and surveillance The implementation of surveillance systems on ICUs and for other patient populations at risk to determine infusion related complication rates, monitor trends and correct lapses in infection control practice have been proven to be successful. E.g. the infection surveillance strategy in the Netherlands were able to reduce MRSA prevalence below 1 % of all clinical isolates and is thus one of the lowest worldwide [48, 49, 50]. Handling issues n All intravenous solution containers must be carefully inspected for cracks, defects, turbidity, and particulate matter before preparation and use. n Intravenous catheters should never be re-inserted. n Routine replacement of IV administration set (see Figure 18) [41]. n As less manipulations as possible should be done on infusion systems as every manipulation bears the risk of contamination. n Maximum sterile barriers should be used whenever possible. Engineerial and technical solutions Use of sterile disposables (see Figure 17) n Use of closed systems and devices n Use of transparent dressings to secure the cannula / catheter n Commercially available intravascular solutions are manufactured and provided sterile. Contamination of infusate solutions rarely occurs during the manufacturing process [46], but is more likely during manipulation and contamination in course of manual preparation [6, 23, 1, 45, 51, 52, 53] n Definition of a Closed System “A device that does not exchange unfiltered air or contaminants with the adjacent environment.” [54] 17 Microbiological Contamination Risk prevention Ecoflac® plus Closed system IV solution container that offers safe and convenient application of all IV procedures from drug admixture to drug delivery.
