- 6. Why are Dialysis Patients at Risk for Infection? • Patients who undergo hemodialysis have a higher risk of infection, due to the following factors: – Frequent use of catheters or insertion of needles to access the bloodstream – Weakened immune systems – Frequent hospital stays and surgery
- 7. • Dialysis patients are at risk of getting hepatitis B and C infections and bloodstream infections – Hepatitis B and C are bloodborne viral infections that can cause chronic (life-long) disease involving inflammation (swelling) of the liver • Hepatitis B and C viruses can live on surfaces and be spread without visible blood – A bloodstream infection is a serious infection that can occur when bacteria or other germs get into the blood • One way bacteria can enter the bloodstream is through a vascular access (catheter, fistula, or graft) Infections in Dialysis Patients
- 8. • Bloodstream infections are a dangerous complication of dialysis • 1 in 4 patients who get a bloodstream infection caused by S. aureus (staph) bacteria can face complications such as: – Endocarditis (infected heart valve) – Osteomyelitis (infected bone) • Total costs for each infection can be more than $20,000 • Bloodstream infections can cause sepsis (a potentially deadly condition) • Up to 1 in 5 patients with an infection die within 12 weeks Infections in Dialysis Patients
- 9. National Burden of Dialysis Infections • In the US, there are about 370,000 people relying on hemodialysis • About 75,000 people receive hemodialysis through a central line • Central lines have a higher risk of infection than a fistula or graft • CDC estimates 37,000 central line- associated bloodstream infections may have occurred in U.S. hemodialysis patients in 2008 A Cause for Concern
- 10. How Do Infections Happen? Three elements must be present for an infection to occur: 1.A source of germs (like bacteria or viruses) 2.A susceptible host, meaning a person who is at risk of getting an infection from the germs 3.A way for the germs to move from the source to the host – There are three ways in which germs move from the source to the host: Contact, Droplet, and Airborne Transmission Contact Droplet Airborne SOURCE HOST

Clean area Photo provided by Stephanie Booth, used with permission
- 31. Dedicate Supplies to a Single Patient • Any item taken to a patient’s dialysis station could become contaminated • Items taken into the dialysis station should either be: – Disposed of, or – Cleaned and disinfected before being taken to a common clean area or used on another patient • Unused medications or supplies taken to the patient’s station should not be returned to a common clean area (e.g., medication vials, syringes, alcohol swabs) Photo provided by Marshia Coe and Teresa Hoosier, used with permission
- 32. Safe Use of Medication Vials • Prepare all individual patient doses in a clean area away from dialysis stations • Prepare doses as close as possible to the time of use • Do not carry medications from station to station • Do not prepare or store medications at patient stations • CDC recommends that dialysis facilities: – Use single-dose vials whenever possible and dispose of them immediately after use
- 33. Guidelines for Carrying Medications • Do not use the same medication cart to deliver medications to multiple patients • Do not carry medication vials, syringes, alcohol swabs, or supplies in pockets • Be sure to prepare the medication in a clean area away from the patient station and bring it to the patient station for that patient only at the time of use
- 34. • Cleaning and disinfection reduce the risk of spreading an infection • Cleaning is done using cleaning detergent, water and friction, and is intended to remove blood, body fluids, and other contaminants from objects and surfaces • Disinfection is a process that kills many or all remaining infection-causing germs on clean objects and surfaces – Use an EPA-registered hospital disinfectant – Follow label instructions for proper dilution • Wear gloves during the cleaning/disinfection process Cleaning and Disinfecting the Dialysis Station
- 35. • All equipment and surfaces are considered to be contaminated after a dialysis session and therefore must be disinfected • After the patient leaves the station, disinfect the dialysis station (including chairs, trays, countertops, and machines) after each patient treatment – Wipe all surfaces – Surfaces should be wet with disinfectant and allowed to air dry – Give special attention to cleaning control panels on the dialysis machines and other commonly touched surfaces – Empty and disinfect all surfaces of prime waste containers Disinfecting the Dialysis Station Photo provided by Stephanie Booth, used with permission
- 36. Safe Handling of Dialyzers and Blood Tubing • Before removing or transporting used dialyzers and blood tubing, cap dialyzer ports and clamp tubing • Place all used dialyzers and tubing in leak-proof containers for transport from station to reprocessing or disposal area • If dialyzers are reused, follow published methods (e.g., AAMI standards) for reprocessing AAMI is the Association for the Advancement of Medical Instrumentation Photo provided by Stephanie Booth, used with permission
- 37. Lesson 4: Policies and Practices Infection Control Policies and Practices for Outpatient Hemodialysis Facilities
- 38. Infection Control Policies and Practices for Dialysis Facilities • Vaccination of dialysis staff and patients • Preventing the spread of hepatitis B • Preventing the spread of bacterial infections
- 39. • Influenza – Influenza or the “flu” is a respiratory infection that infects the nose, throat, and lungs – The flu is spread mainly by droplets that are made when people with flu cough, sneeze or talk – The single best way to prevent the flu is to get a flu vaccine each year • Hepatitis B – Hepatitis B is a serious infection that affects the liver. It can cause acute (short-term) or chronic (long-term) infection and liver cancer – Hepatitis B virus is easily spread through contact with the blood or other body fluids of an infected person – Hepatitis B vaccine can prevent hepatitis B infection Vaccine-Preventable Infections
- 40. Take Care of Yourself Get Vaccinated • Get the flu vaccine each year • Complete the hepatitis B vaccine series
- 41. Vaccination and Routine Testing of Hemodialysis Patients • Vaccinate all susceptible patients against: – Hepatitis B • Recommended vaccines for patients include: – Influenza (inactivated) – Pneumococcal • Conduct routine testing for: – Hepatitis B virus – Hepatitis C virus
- 42. Preventing the Spread of Hepatitis B • Dialyze hepatitis B (HBsAg+) patients in a separate room using separate machines, equipment, instruments, and supplies – Be sure to use a separate gown when treating these patients • Staff members caring for patients with hepatitis B (HBsAg+) should not care for HBV-susceptible patients at the same time (e.g., during the same shift or during patient changeover) • HBsAg+ means hepatitis B surface antigen (a lab test for hepatitis B virus) was positive • HBV-susceptible means anyone who has never been infected and lacks immunity to hepatitis B virus
- 43. Preventing the Spread of Bacterial Infections • Hemodialysis patients who might be at increased risk for spreading germs to other patients include those with: – An infected skin wound with drainage that is not contained by dressings – Fecal incontinence or uncontrolled diarrhea • For these patients use the following precautions: – Wear a gown and gloves when you are caring for the patient and remove the gown and gloves when you are finished caring for the patient – Do not wear the same gown when caring for other patients – Dialyze the patient at a station with as few adjacent stations as possible (e.g., at the end or corner of the room) • Patients with respiratory illness and a fever are at risk of spreading bacterial and viral respiratory infections – These patients should be dialyzed at least 6 feet away from other patient stations or any shared supplies
- 44. Lesson 5: Education Educating your Patients and their Caregivers
- 45. • Advise patients to inform you if they notice any of the following possible signs of infection: – Fever – The access site is: • Swollen (bulging), • red, • warm, or • has pus – Severe pain at the access site Remember: infections of the vascular access site can be life threatening How to Recognize an Infection
- 46. Training and Education of Patients and their Caregivers • When a new patient starts dialysis and on an annual basis, review: – Personal hygiene and hand hygiene technique – Patient responsibility for proper care of the access site and recognition of signs of infection – Recommended vaccinations (including hepatitis B, influenza, and pneumococcal) – Reasons for selecting a fistula or graft over a catheter to lower the risk of infection
- 47. Recap Preventing Infections in Hemodialysis Settings Photo provided by Stephanie Booth, used with permission
- 48. Key Infection Prevention Practices • Perform hand hygiene frequently and change gloves • Maintain separate clean areas for supplies and medications and separate contaminated areas for used items • Practice proper handling and delivery of patient supplies and medications • Perform effective cleaning and disinfection of dialysis equipment and environmental surfaces • Carefully handle medications and the patient’s vascular access to avoid contamination Remember: Use aseptic technique every time!
- 49. Conclusion • Infections that patients can get while receiving dialysis are serious and preventable! • Healthcare workers like you following infection control precautions and other safe care practices are the key to prevention • Infection prevention is everyone’s responsibility

There are instructions at the end of the course that will direct you on how to receive CE credit.
- This course is comprised of the following lessons: Lesson 1: Infections that Patients Can Get from Hemodialysis Lesson 2: Standard Precautions for all Healthcare Workers in all Healthcare Settings Lesson 3: Specific Infection Control Recommendations for Outpatient Hemodialysis Healthcare Workers Lesson 4: Infection Control Policies and Practices for Outpatient Hemodialysis Facilities Lesson 5: Educating your Patients and their Caregivers Following these lessons there is a brief recap of course material, followed by the course assessment.
- In the first lesson, we will discuss infections that patients can get from hemodialysis. We will begin with a patient’s story, followed by the reasons dialysis patients are at risk for infection, and some statistics on dialysis infections. Then we will review how infections happen in general, how they can be spread in outpatient hemodialysis facilities, and what you can do to prevent the spread of infections.
- First we’d like to share a personal story about Brian Hess, a 22 year old patient receiving outpatient hemodialysis. At the time of his infection he was new to living on his own and trying to finish a college degree. His central venous access port became infected and once the port and the connecting lines became infected, his healthcare workers could not seem to get rid of the infection. They tried to eliminate the infection for several weeks using antibiotics, but in the end, they were only able to clear the infection by removing the port and all parts of his infected access. Brian learned very well how central venous access ports are so likely to become infected and stay that way. He writes, “the entire year was very taxing for me both physically and mentally.” Brian’s story shows how an infection can cause loss of the vascular access, which is the patient’s lifeline.
- So why are dialysis patients like Brian at risk for infection? Hemodialysis patients are at a high risk for infection because the process of hemodialysis requires the frequent use of catheters or insertion of needles to access the bloodstream. Also, hemodialysis patients have weakened immune systems, which increases their risk for infection, and they require frequent hospitalizations and surgery where they might acquire an infection.
- This slide describes the kinds of infections that hemodialysis patients are at risk of getting, including Hepatitis B and Hepatitis C infections, and bloodstream infections. Hepatitis B and C are bloodborne viral infections that can cause lifelong disease involving swelling of the liver. Of particular concern in the dialysis setting is the fact that the hepatitis B and C viruses can live on surfaces like dialysis chairs and machines and can be spread even when you don’t see any blood. A bloodstream infection is a serious infection that can occur when bacteria or other germs get into the blood. One way bacteria can enter the bloodstream is through a vascular access.
- Bloodstream infections are a dangerous complication of dialysis. As many as one in four or 25% of patients who get a bloodstream infection caused by staph bacteria will face complications such as endocarditis, which is an infected heart valve, or osteomyelitis, which is an infection of the bone. The total costs to treat an infection can be more than $20,000 for hospitalized patients. Bloodstream infections can also lead to sepsis, a potentially deadly condition, and up to one in five or 20% of hospitalized patients with an infection die within 12 weeks.
- In this slide we consider just how common infections are among dialysis patients, especially those with central lines. In the United States, there are about 370,000 people relying on hemodialysis care. About 75,000 people receive hemodialysis through a central line. Central lines have a higher risk of infection than a fistula or graft. The CDC estimates that 37,000 central line associated bloodstream infections may have occurred in U.S. hemodialysis patients in 2008. Healthcare workers and dialysis facilities can do several things to prevent bloodstream infections and protect patients.
- First it’s important to understand how these infections are happening in order to prevent them. Three elements must be present for an infection to occur: The first is a source of germs like bacteria or viruses. Often the source is a person who may or may not appear to be sick, but the source can also be surfaces in the environment. The second is a susceptible host, meaning a person who is at risk of getting an infection from the germs. This person must have a way for the germs to enter the body like vascular access ports, other cuts or breaks in the skin, and even mucous membranes like the eyes, nose, and mouth. The third is a way for the germs to move from the source to the host in healthcare settings. There are three ways in which germs move from the source to the host, shown above in the red arrows: Contact, Droplet, and Airborne Transmission. On the next slide we will review these three transmission routes in detail.
- During dialysis, infections like Hepatitis B and C and bloodstream infections, like those caused by staph bacteria, are spread most commonly by contact transmission. Contact transmission occurs when a person with germs, known as the source, touches an object or surface which contaminates that object or surface, or is touched by a healthcare worker, which contaminates the healthcare worker. Another person, known as the host, touches the contaminated object or surface, or is touched by the same healthcare worker, and germs enter their body through their mucous membranes or breaks in the skin and cause infection. A common mode of transmission is by healthcare worker hands. For example, healthcare workers may spread germs after touching an infected body site on one patient and then touching another patient’s catheter port for example, if they do not perform hand hygiene. Also, patient-care devices like blood pressure cuffs or glucometers may transmit pathogens if they are contaminated with blood or body fluids and then shared between patients without first cleaning and disinfecting.
- Respiratory infections are typically spread through Droplet or Airborne transmission. With Droplet Transmission, an infected person, known as the source, coughs, sneezes or talks, which creates droplets that carry germs from the infected person to another person known as the host. These droplets only travel a short distance and enter through the mucous membranes such as the eyes, nose, or mouth of the host to cause infection. With Airborne Transmission, an infected person known as the source coughs or sneezes, which creates particles of germs in the air that can remain contagious over time and travel long distances. Another person known as the host inhales or breathes in these particles, possibly without ever being in the same room with the source, and can get the infection. Certain infections are spread primarily by certain routes. For example, the flu is spread primarily by droplet transmission while tuberculosis is spread by airborne transmission. Although not as common as germs spread by contact transmission, germs like the flu and tuberculosis can be spread in dialysis units.
- Now that we know how infections can be spread, we turn our attention to what healthcare workers like you can do to prevent the spread of infections. The answer is simple – understand and follow the basics of infection control as a routine part of your practice. All healthcare workers, no matter where they practice, are expected to follow Standard Precautions for infection control. In lesson 2 we will review the main concepts of Standard Precautions. In addition, CDC has developed specific recommendations that are tailored for hemodialysis healthcare workers that take into account the increased risks for infection that are present in outpatient hemodialysis facilities. In lesson 3 we will review the main concepts of the dialysis-specific recommendations to prevent infections.
- In this lesson, we will review Standard Precautions. Standard Precautions are a set of CDC recommendations that assume that any patient can have an infection. They are intended to be applied to the care of all patients in all healthcare settings.
- All healthcare workers are expected to follow Standard Precautions for infection control. This includes performing hand hygiene, using personal protective equipment or PPE, and following safe injection practices. We will review these concepts in more detail in the next few slides.
- The first concept of Standard Precautions is to perform hand hygiene. Hand hygiene is one of the most important ways to prevent the spread of infections. Hand hygiene is a general term that applies to either washing hands with soap and water or using an alcohol-based hand rub product. When your hands are visibly dirty, especially with blood or other body fluids, it is best to wash them with soap and water. To wash your hands properly, wet your hands with water and use liquid soap if possible. Rub your hands together until the soap forms a lather and then rub all over the top of your hands, in between your fingers and the area around and under the fingernails. Continue rubbing your hands for at least 15 seconds. Rinse your hands well under running water and dry them using a paper towel if possible. If your hands are not visibly dirty, use an alcohol-based hand rub. Follow the directions on the bottle for how much of the product to use. Rub your hands together and rub the product all over the top of your hands, in between your fingers and the area around and under the fingernails. Continue rubbing until your hands are dry. If enough product was used, it should take at least 15 seconds of rubbing before your hands feel dry. When using an alcohol-based hand rub, you should not rinse your hands with water or dry them with a towel. Remember that hand hygiene is one of the most important ways for you to prevent the spread of infections.
- There are many times in the course of patient care that it is necessary for you to perform hand hygiene, including: Before you touch a patient Before you inject or infuse a medication Before you cannulate a fistula or graft or access a catheter After you touch a patient After you touch blood, body fluids, mucous membranes, wound dressings, or dialysis fluids like spent dialysate After you touch medical equipment or other items at the dialysis station After you remove gloves If you follow these guidelines for performing hand hygiene, you will greatly reduce the chances of spreading an infection from one patient to another.
- The next concept within Standard Precautions is using personal protective equipment or PPE. Using PPE is for your own protection from infections and using it correctly will also protect your patients. In all healthcare settings, you are expected to wear gloves, a gown, or face protection such as a face shield, or goggles and a face mask when you think you may come into contact with blood or other potentially infected body fluids, mucous membranes, or nonintact skin. Because of the risk for blood exposure in hemodialysis settings, glove use is recommended for all patient care in outpatient dialysis facilities. We will discuss this more in detail in the next lesson. While using PPE is for your own protection from infections, you need to be mindful to change your PPE, especially gloves, at certain times so that your gloves do not spread infections from patient to patient. Change your gloves if you will be touching a clean body site after a contaminated body site. Remove your gloves after contact with a patient and/or the surrounding environment, including medical equipment. And finally, do not wear the same pair of gloves for the care of more than one patient. These practices will help you use personal protective equipment properly.
- The last concept within Standard Precautions is following safe injection practices. Safe injection practices are a basic expectation any time injections are administered. Over the last decade, syringe reuse and misuse of medication vials have resulted in dozens of outbreaks of bloodborne viruses such as hepatitis B and hepatitis C, including in dialysis centers. Medications are injected directly or indirectly into the patient’s bloodstream, therefore any germs that have entered the medication vial or syringe can cause serious infections in the patient. Germs also can be introduced at the time of injection, for example, through a contaminated injection port.
- Here are the three things you should know about safe injection practices: First, needles and syringes are single use devices. You should never use them for more than one patient or reuse them to draw up additional medication. Second, do not administer medications from a single-dose vial or IV bag to multiple patients. Bags of saline or medication are single-use items. And finally, perform hand hygiene and cleanse any catheter or IV access port before injecting into it or withdrawing from it. These practices will help prevent the spread of bloodborne viruses and other germs.
- Now that we have reviewed the main concepts of Standard Precautions, in this lesson we will review the specific infection control recommendations for outpatient hemodialysis settings. Healthcare workers are expected to follow these recommendations in addition to Standard Precautions to help prevent the spread of infections in dialysis facilities.
- Some of the specific infection control recommendations for outpatient hemodialysis healthcare workers include: Wear gloves and other personal protective equipment or PPE for all patient care Promote vascular access safety Clean and disinfect the dialysis station between patients Separate clean areas from contaminated areas Use medication vials safely Perform safe handling of dialyzers We will learn more about each of these concepts in the following slides.
- The first dialysis specific infection control recommendation is to wear gloves during patient care. You should wear gloves for your own protection from infections, and you have to use them correctly to protect your patients from infections. During the process of hemodialysis, exposure to blood and contaminated items can be expected; therefore, gloves are required in the dialysis environment whenever caring for a patient or touching equipment or surfaces at the dialysis station. Gloves should also be worn when cleaning surfaces in the environment or medical equipment. Remember to remove your gloves and perform hand hygiene between each patient or station and if moving from a contaminated to a clean area of the same patient or within the same dialysis station. These practices will help prevent the spread of infections.
- Similarly, while personal protective equipment is a concept of Standard Precautions, it is also a concept of dialysis-specific infection control recommendations. You should wear gloves, gowns, and face protection such as a face shield or goggles and a face mask to protect yourself when performing procedures during which blood splashes might occur. This includes during initiation and termination of dialysis, when cleaning dial yzers, and when spinning blood samples. Personal protective equipment should be changed if it becomes soiled with blood, body fluids, secretions, or excretions.
- The next concept in the dialysis-specific infection control recommendations is practicing vascular access safety. As we learned in lesson 1, infections are all too common, particularly with central lines. In the next four slides, we will review the cannulation and decannulation procedures for patients who have fistulas or grafts, followed by the connection and disconnection procedures for patients who have catheters. One concept that we will mention in these next several slides is aseptic technique. When performing a procedure such as cannulating a fistula or graft, aseptic technique means taking great care not to contaminate the fistula or graft site before or during the procedure. Here we describe the cannulation procedure for patients with fistulas or grafts: Have the patient wash the site with soap and water Perform hand hygiene Put on a new, clean pair of gloves Wear proper face protection Apply skin antiseptic such as chlorhexidine, povidone iodine, or alcohol to the site and allow it to dry Perform cannulation being careful not to contaminate the area that has been cleansed Remove gloves and perform hand hygiene CDC recommends using safety needles to decrease your chances of getting a needlestick.
- When the patient has completed treatment, here are the steps for the decannulation procedure in patients with fistulas or grafts:\ Perform hand hygiene Put on a new, clean pair of gloves Wear proper face protection Activate the safety devices on the needles to prevent a needlestick, remove needles using aseptic technique and dispose of them in a proper sharps container Apply clean gauze or a bandage to site Compress the site with clean gloves Remove gloves and perform hand hygiene
- Practicing vascular access safety is of particular importance in patients with catheters or central lines, as the risk of infection is highest in these patients. To properly perform a catheter connection procedure, use the following steps: Perform hand hygiene. Put on a new, clean pair of gloves. Some centers may choose to use sterile gloves. Wear proper face protection. A face mask may be required in your center. While keeping the catheter clamped, apply antiseptic to the catheter hub, which is the end of the catheter, and allow it to dry. Be careful not to contaminate the catheter hub after applying the antiseptic. Connect the catheter to blood lines using aseptic technique. Keep the catheter clamped until after it’s connected to avoid allowing air to enter the catheter. Unclamp the catheter once it is connected. Remove gloves and perform hand hygiene.
- When the patient has completed treatment, here are the steps for the disconnection procedure in patients with catheters: Perform hand hygiene. Put on a new, clean pair of gloves. Some centers may choose to use sterile gloves. Wear proper face protection. A face mask may be required in your center. After clamping the catheter, disconnect the catheter from the blood lines using aseptic technique. Apply antiseptic to the catheter hub and allow it to dry. Replace caps using aseptic technique. Check to make sure the catheter remains properly clamped. Remove gloves and perform hand hygiene.
- Here are the additional steps for caring for a catheter exit site. This can be done anytime prior to, during, or after dialysis treatment: Perform hand hygiene Put on a new, clean pair of gloves. Some centers may choose to use sterile gloves. Wear a face mask if required in your center. Apply antiseptic to catheter exit site and allow it to dry Apply antimicrobial ointment Apply clean dressing to exit site Remove gloves and perform hand hygiene
- The next concept in the dialysis-specific infection control recommendations is keeping clean areas separate from contaminated areas. Clean areas should be clearly designated and used only for the preparation, handling and storage of medications and unused supplies and equipment. In your center, there should be clean medication and clean supply areas. Ideally these are in a separate room, physically separate from the rest of the treatment area, which allows you to better maintain the cleanliness of the area. Clean areas should be clearly separated from contaminated areas where used supplies and equipment are handled. Do not handle or store medications or clean supplies in the same area as where used equipment or blood samples are handled. Remember: treatment stations are contaminated areas!
- The next concept in the dialysis-specific infection control recommendations is to dedicate supplies to a single patient. Any item taken to a patient’s dialysis station could become contaminated with blood or other body fluids. Patient care items taken into the dialysis station should either be: Disposed of, or Cleaned and disinfected before being taken to a common clean area or used on another patient. Unused medications or supplies, for example, medication vials, syringes, or alcohol swabs, that are taken to the patient’s station should not be returned to a common clean area.
- The next concept in the dialysis-specific infection control recommendations is to practice safe use of medication vials. These recommendations are part of safe injection practices under standard precautions for all healthcare workers. Most of your patients will require injected medications such as heparin, saline, or erythropoietin. When preparing these medications: Prepare all individual patient doses in a clean area away from dialysis stations. Prepare doses as close as possible to the time of use, meaning, do not draw up medications in advance. Do not carry medications from station to station. Do not prepare or store medications at patient stations. CDC recommends that dialysis facilities: Use single-dose vials whenever possible and dispose of them immediately after use.
- The next concept in the dialysis-specific infection control recommendations is to carry medications properly in order to avoid spreading infections. These guidelines include: Do not use the same medication cart to deliver medications to multiple patients. Do not carry medication vials, syringes, alcohol swabs, or supplies in pockets. Be sure to prepare the medication in a clean area away from the patient station and bring it to the patient station for that patient only at the time of use.
- The next concept in the dialysis-specific infection control recommendations is cleaning and disinfecting the dialysis station. Both cleaning and disinfection are performed to reduce the risk of spreading an infection. Cleaning is done using cleaning detergent and water and is intended to remove blood and body fluids from objects and surfaces. Disinfection is a process that kills many or all of the remaining germs on clean objects and surfaces. To properly perform disinfection, use an EPA-registered hospital disinfectant. Follow the label instructions for proper dilution. Note that different disinfectants will have different instructions for making up the solution and this can vary for routine disinfection versus cleaning up a blood spill. Be sure to check the label. Also, be sure to wear gloves and other PPE that is recommended on the product’s label during the cleaning and disinfection process.
- Disinfection is performed specifically because blood and germs can contaminate surfaces and spread infections without being visible to the naked eye. It is important to follow thorough disinfection procedures even when you don’t see blood. The disinfection process should not begin until the patient has completed treatment and has left the station. Disinfect the dialysis station including chairs, trays, countertops, and machines after each patient treatment Wipe all surfaces Surfaces should be wet with disinfectant and allowed to air dry Give special attention to cleaning control panels on the dialysis machines and other commonly touched surfaces Empty and disinfect all surfaces of prime waste containers and make sure these are dry before using them Be careful not to contact the surfaces with used or contaminated items once the disinfectant is applied.
- The last concept in the dialysis-specific infection control recommendations is to practice safe handling of used dialyzers and blood tubing. Before removing or transporting used dialyzers and blood tubing, cap dialyzer ports and clamp tubing. Place all used dialyzers and tubing in leak-proof containers for transport from station to reprocessing or disposal area. If dialyzers are reused, initiate reprocessing immediately after use and follow published methods, for example, AAMI standards, for reprocessing the dialyzers.
- We have reviewed how infections are spread from patient to patient in dialysis facilities, as well as standard precautions for all healthcare workers and the dialysis-specific infection control recommendations. In this lesson, we will review the infection control policies and practices for outpatient hemodialysis facilities. These are important for dialysis nurses and technicians to be aware of.
- Infection control policies and practices for dialysis facilities include the following concepts: Vaccination of dialysis staff and patients Preventing the spread of Hepatitis B Preventing the spread of bacterial infections We will review these concepts in greater detail in the next few slides.
- First we’d like to review two infections that dialysis patients and staff are at a high risk of spreading. Influenza or the “flu” is a respiratory infection that infects the nose, throat, and lungs. Every year, thousands of people die from the flu. The flu is spread mainly by droplets that are made when people with flu cough, sneeze or talk. The single best way to prevent the flu is to get a flu vaccine each year. Hepatitis B is a serious infection that affects the liver. It can cause acute short-term or chronic long-term infection as well as liver cancer. Hepatitis B virus is easily spread through contact with the blood or other body fluids of an infected person. Hepatitis B vaccine can prevent hepatitis B infection. Because it can be easily spread due to all of the blood in the dialysis environment, it is important to vaccinate anyone who has never been vaccinated and lacks immunity. This applies to both patients and dialysis healthcare workers.
- It is important to take care of yourself and be a role model for your patient while working in a dialysis center. All dialysis healthcare workers should get the flu vaccine each year and complete the Hepatitis B vaccine series to protect themselves from these infections. Healthcare workers can have the flu and spread it even if they don’t feel sick. Getting the flu vaccine lessens your chances of spreading the flu to your patients or family members such as older adults or infants.
- In addition to taking care of yourself, it is important to vaccinate and perform routine testing of hemodialysis patients. This includes: Vaccinate all susceptible patients against Hepatitis B. In this case, susceptible means any patient who has never been vaccinated and lacks immunity to hepatitis B virus. Ideally, patients should be vaccinated against Hepatitis B before they require dialysis. In addition, it is recommended that dialysis patients receive the inactivated influenza vaccine each year and the pneumococcal vaccine. Hemodialysis patients should be routinely tested for: Hepatitis B and Hepatitis C virus. In addition, all healthcare workers should receive the influenza vaccine annually and dialysis healthcare workers also should receive the Hepatitis B vaccine series.
- The next infection control policy for dialysis facilities is to properly manage patients who have Hepatitis B in order to prevent the spread of the infection. With these patients, follow the same infection control recommendations, including standard precautions and the dialysis-specific infection control recommendations, as you would for all patients.In addition, dialyze patients with Hepatitis B in a separate room using separate machines, equipment, instruments, and supplies. Be sure to use a separate gown when treating these patients. Staff members who are caring for patients with Hepatitis B should not care for patients who are susceptible to hepatitis B at the same time, for example during the same shift or during patient changeover. Some centers have designated one person to care for Hepatitis B patients to help prevent the spread of hepatitis B virus from patient to patient.
- The last infection control policy for dialysis facilities is to properly manage dialysis patients with bacterial infections to prevent the spread of these infections. This applies to patients who have an infected skin wound with drainage that is not contained by dressings and patients with fecal incontinence or uncontrolled diarrhea. Of course these patients will come for their dialysis treatment when they are sick, and they pose a risk to other patients. You should alert your clinic or nurse manager if you notice a patient with any of these symptoms. And, remember you should always follow standard precautions and the dialysis-specific infection control recommendations, including strict attention to hand hygiene. In addition, you should wear a gown when you are caring for the patient and remove the gown when you are finished caring for the patient. Make sure you do not wear the same gown or gloves when caring for other patients. Patients with these conditions should be dialyzed at a station with as few adjacent stations as possible, for example at the end or corner of the room. Patients with respiratory illness and a fever are at risk of spreading bacterial and viral respiratory infections. Because these infections are often spread by droplet transmission, these patients should be dialyzed at least 6 feet away from other patient stations or any shared supplies, including computer keyboards for example. They should be encouraged to follow proper cough etiquette like coughing into a tissue, discarding it, and performing frequent hand hygiene. If tissues are not available, patients can cough into their elbow. For all of these patients, it is essential that staff perform hand hygiene and change gloves between patients.
- In this final lesson we will review important concepts to discuss with your patients and their caregivers.
- First, please advise all patients and their caregivers on how to recognize an infection. They should tell you or another healthcare worker if they notice any of the following signs of infection: Fever The access site is swollen or bulging, red, warm, or there is pus at the site Severe pain at the access site Remember that infections of the vascular access site can be life threatening.
- As a matter of routine, when a new patient starts dialysis and on an annual basis, please review: Personal hygiene and hand washing technique. Patient responsibility for proper care of the access site and recognition of signs of infection. Recommended vaccinations including hepatitis B, influenza, and pneumococcal. And if the patient is a potential candidate for a fistula or graft, the reasons they should choose these access types instead of a catheter. These practices will help lower their risk of infections.
- In the following slides we will briefly review what you have learned in this course.
- The following are key infection prevention practices to keep in mind: Perform hand hygiene frequently and change your gloves at appropriate times Maintain separate clean and contaminated areas Practice proper handling and delivery of patient supplies and medications Perform effective cleaning and disinfection of dialysis equipment and environmental surfaces Carefully handle medications and the patient’s vascular access to avoid contamination
- In conclusion, infections that patients can get while receiving dialysis are serious and preventable! Healthcare workers like you following infection control precautions and other safe care practices are the key to prevention. Infection prevention is everyone’s responsibility.
