Article #1: Prevention and Control of Clostridium Difficile Infection

Clostridium difficile (C. diff) is an anaerobic Gram-Positive bacillus. Infection with C. diff usually happens when the normal flora in the colon is altered because of broad-spectrum antibiotic use. Symptoms of C. diff  range from mild diarrhea to profuse, watery diarrhea. Instances of large areas of intestinal epithelium becoming necrosed with ulceration and life-threatening perforation have occurred.
Transmission of C. diff is by the fecal-oral route. Transmission can take place in the hospital from the workers and environmental reservoirs (urinals, bedpans). Spores can live month or years if not properly destroyed by detergent. Treatment of C. diff can be done by IV vancomycin or oral metronidazole. Infection prevention and control can be accomplished through meticulous hand hygiene, isolating the patient, and environmental cleaning. Hand hygiene (using soap, water and friction and avoiding alcohol products as they are not effective and do not kill the spores) and Personal Protective clothing (such as gown, gloves, and shoe covers) can help to prevent and control the spread of the disease.

Article #2: Clostridium Difficile Infection: Risk factors, diagnosis and control

Clostridium difficile (C. diff) is one of the most common causes of nosocomial diarrhea in humans. Morbidity and mortality rates for C. diff have increased in many developed countries and is estimated to be responsible for about 3 million cases of diarrhea and colitis each year. C. diff spores pass through the gastric acid in the stomach and germinate in the small intestine.. C. diff may be accompanied by toxic mega colon, electrolyte imbalance and occasional bowel perforation. There are several risk factors associated with C. diff. Age, immunoglobulin level, antibiotic treatment, surgical manipulation, and antacid and other treatment regimes. C. Diff is transmitted by commonly  touched surfaces in hospitals such as bed rails, telephones, call buttons, door knobs, toilet seats and bedside tables of rooms in which the patient has C. diff. Treatment and control include metronidazole and vancomycin, and avoiding unnecessary proton pump inhibitors. Health care workers must wear gloves, appropriate chemicals need to be used to clean and disinfect.  Disinfection with 10% bleach and chlorine-based compounds are shown to inactivate C. diff spores.

Article #3: Clostridium difficile: Implications for nursing

Clostridium difficile is a health care challenge due to the many complications it can cause (hypovolemia, sepsis, pain, peritonitis). C. difficile colonizes in approximately 40% of hospitalized patients due to the spores frequently present in the environment on the floors, side rails, bathroom and health care worker’s hands. Signs and symptoms of C. difficile include abdominal fullness, abdominal discomfort, malodorous frequent loose stool, elevated white blood count, elevated temperature, and signs of dehydration. Nursing management includes discontinuing the prescribed antibiotic, administering a different antibiotic to treat the infection, assessment of temperature, WBC count, skin care, assistance with bowel elimination. Also important is the use of contact precautions, keeping surfaces disinfected with hypochlorite-based cleanser or household bleach diluted with water (1:10)/. It is important to teach patients and their families to wash their hands with soap and water and not use alcohol based cleansers as they are not effective.

Article #4: Hospital infection control strategies for vancomycin-resistant Enterococcus, methicillin-resistant Staphylococcus aureus and Clostridium difficile

Four key hospital interventions are the cornerstone for infection control of Clostridium difficile among other diseases. These cornerstones are hand hygiene, environmental cleaning, barrier precautions and screening. Patients who have an infections serve as reservoirs for microorganisms. Risk factors for colonization include age, severity of illness and the use of antibiotics. Although alcohol based cleansers are an important part of hand hygiene they are not effective in killing C. difficile, only the use of soap and water is. Keeping a clean environment and using disinfectant solutions known to kill the virus. Barrier precautions to use include gloves and gown and placing the patient in contact precaution and a private room. Screening ill patients who show symptoms of C. diff and identifying patients who are ill in a timely manner so treatment can begin is imperative to treating and reducing the spread of the disease.

Article #5: Clostridium difficile- Associated Disease Diagnosis, Prevention, Treatment, and Nursing care

Clostridium difficile-associated disease (CDAD) includes diarrhea, pseudomembranous colitis, toxic megacolon, perforation of the colon, and in some cases, sepsis. The use of high-risk antibiotics, reduction in housekeeping staff, increased nursing workloads, antiquated facilities and general changes in hospital populations (increased number of immunocompromised, debilitated, and elderly patients) and contributing factors. C. diff spores are resistant to many types of disinfectants, heat and dryness and may remain on surfaces for months. Transmission is via the fecal-oral route. Healthy people are able to keep C. diff at bay due to the healthy flora in the gut. The use of antibiotics and medications and decrease stomach acidity, such as proton pump inhibitors cause the bacteria to proliferate. To prevent the spread of C. diff hands must be washed with an antimicrobial soap for at least 15 seconds. Hands should be washed before and after contact with a patient and after glove removal. Cleaning with 1:10 bleach solution is recommended. High touch surfaces such as doorknobs, light switches, call lights, television remote control, soap dispensers, faucets, bed rails and telephones need frequent cleaning. Nursing care includes preventing dehydration, promoting comfort, and maintaining skin integrity.

Article #6: In the Clinic: Clostridium difficile Infection

Transmission occurs through the fecal-oral route, usually by person-to-person transmission. Contaminated fomites and the hands of health care workers are another source of transmission. The primary means of prevention are to limit the use and type of antibiotics and to adhere to infection control measures. This includes using the appropriate environmental cleaning solutions, limiting the use of antibiotics, and strict hand washing. Conventional hand washing with soap and water should be adhered to when caring for patients during an outbreak or suspected outbreak. Wearing gloves and gowns if contact with patient is to occur is also necessary (the use of gowns has not had any trials however is recommended because C. diff has been cultured from the uniforms of workers).

Article #7: Preventing healthcare-associated infections: risks, healthcare systems and behaviour.

Modern health care generates a wide range of infection risks for patients through practices that compromise the patient against infection. To prevent infections from spreading the use of hand hygiene is important. During the normal work activities of the healthcare provider, they transfer a patient’s own microorganisms from one body site to another, they transfer microorganisms from one patient to another patient, they transfer microorganisms to and from the equipment they are working with. Portable equipment must be cleaned and disinfected prior to contact with a patient and their environment.

Article #8: Role of hand hygiene in healthcare-associated infection prevention

Healthcare workers’ hands are the most common vehicle for the transmission of healthcare-associated pathogens from patient to patient. Optimal hand hygiene is considered the cornerstone of healthcare-associated infection prevention. Following the widespread use of alcohol-based hand rubs concern has been raised about their lack of efficacy against spore forming pathogens. Friction while washing hands with soap and water may help to physically remove spores from the surface of contaminated hands. The use of alcohol based hand rubs has been blamed for the increase in C. diff associated disease rates although there has not been a study to prove this to date of this article. The improvement of healthcare workers compliance to hand hygiene will decrease the spread of infection within the hospital setting.
