Chain of Infection

Dirty equipment – having dirty equipment which is not cleaned between patients can spread infection very fast lots of bacteria can be spread on a blood pressure cuff for example.

Before I started the assessment I used alcohol gel to decontaminate my hand. NICE (2006) states that hand must be decontaminated before each and every episode of direct patient care. It is important to decontaminate my hand to prevent cross-infection of micro-organisms from staff to patient, for example Hospital Acquired Infection. I realised that I am going to have contact with body fluid and blood therefore I put on a pair of latex gloves and disposable plastic apron. Wandsworth Teaching Primary Care Trust May (2008) states that ‘Personal Protective Equipment is designed to protect the healthcare worker from coming into contact with potentially infectious body fluids. It may also protect the patient from the healthcare workers own microbial flora’.

All areas that are being used for healthcare activities should be cleaned with either disinfectant wipes each morning and in between patients/procedures. Equipment should be all new out of the packets and clean. For things more major such as vasectomy’s, minor surgery or family planning clinics, areas should be cleaned everywhere with a disinfectant fluid and also with wipes, gloves should always be worn as well as other PPE such as aprons and hats. All equipment should be new from the packet and only touched by the person who is using

Germs and many other diseases spread primarily through airborne particles, skin to skin contact, and or touching objects such as door handles, hospital buttons, or by sharing patient possessions. Nurses and other health care clinicians are constantly in physical contact with many different patients, who all have varying illness’ and diseases themselves. Many may also carry a

The standard precautions are implemented at all times to decrease the risk of transmitting infectious agents. Assuming that all patients could carry an infection, this minimises the potential spread of HAI’s. These standard precautions include routine hand hygiene, the use of personal protective equipment, safe handling and disposure of sharps and routine environmental cleaning.4,5 In this situation, where blood is present, this is considered a biohazard. Hand hygiene must be performed before touching the patient, before and after any procedures or exposure to bodily substances and after touching the patient or any of the patient’s surroundings. The use of Personal protective equipment should be used when attending to the patient. This includes protective eye wear, a surgical mask and an apron for protection from any splashes or sprays of blood generated by the patient. Gloves should also be worn for single use only when coming in contact with open skin and bodily fluids. To minimise the spread of blood, the bystander with visibly soiled hands should also be advised to thoroughly clean them with soap and

Your own personal conduct; by wearing the appropriate clothes, jewellery and protective clothing to ensure that risks of cross contamination and risks of harm are reduced.

Contact precautions include: the patients being placed in private rooms, performing proper hand hygiene with antimicrobial soap and water, using friction for 15 seconds, and using gloves and gowns during patient care (Keske and Letizia 332). “One should also ensure adequate cleaning and disinfection of environmental surfaces and reusable devices. The uses of both buffered and buffered phosphate hypochlite solutions (bleach) have been shown to decrease the rate of C. difficile contamination and helps in reducing Clostridium Difficile associated disease (CDAD) rates” (Patel 104).

A campaign called, “Clean Hands Save Lives” endorsed by the CDC in the year 2015 put an emphasis on five simple steps to avoid or reduce illnesses. The steps are the following and to be carried out in that order: wet, lather, scrub, rinse, and dry (Potter, Perry, Stockert, & Hall, pg. 458). In addition to performing hand hygiene, gloves must also be used when handling any type of specimen. The use of PPE or Personal protective equipment is important as it protects the wearer from any type of injury or infection. (PPE) Healthcare facilities disclose the type of contact precaution outside a patient’s door. For example, a label for Airborne Precautions indicate that a respiratory protection device (N95 respirator) must be worn in order to enter the room and while interacting with the patient. A room with Droplet Precautions requires the use of a mask or respirator. On the other hand, a room with Contact Precautions indicates the use of gloves and gowns, and a room with category Protective Environment requires protection with HEPA filtration, mask, gloves, and gowns (Potter et al., pg 459).

Infection control practices and procedures should be followed at all times to control infections and prevent them from spreading. Most infection control policies include: wearing the appropriate personal protective equipment for each situation, carrying out risk assessment to reduce risk of exposure to infections for all individuals, disposing of waste properly, and hand hygiene before and after any physical contact. By following these policies in residential care settings, residents are less likely to contract an

The hospital is compliant with infection control protocol according to the CDC standard guidelines. “Hand hygiene, contact precautions, as well as cleaning and disinfecting patient care equipment and the patient’s environment are essential strategies for preventing the spread of health care–associated infections. Hand hygiene is addressed in NPSG.07.01.01. Contact precautions for patients with

There are six elements in the chain of infection. 1. Infectious agent (an organism was the ability to cause disease). 2. A reservoir (a place where organism reproduced such as animals, humans etc.).

A communicable disease chain is the mechanism by which an infective agent or pathogen is transmitted. The chain requires an infective agent, a source of infection, a mode of transmission and a host. An example of an infective agent could be bacteria, a virus, fungus, protozoan or helminth. The source of infective agents can be transmission from host to host, an infected human or animal, insects, soil or livestock. The mode of transmission is how the infective agent is carried from host to host. Transmission can be by air, ingestion or physical contact. To complete a life cycle or to replicate, the infective agent requires a host.

Relating back to my previous work I noted that it was essential that nurses wore aprons during patient care, ensuring that they discarded of them after patient contact. Not only does wearing an apron act as a barrier it is also recognised as a type of PPC (Personal protective clothing). Cadlin J, Stark S (2005) suggests that the Health and Safety Executive (HSE) (1991, 1992) says “Health and Safety Regulations require that all healthcare employees are provided with personal protective clothing”. However McCullough (1998) suggests that nurses’ uniforms are not considered protective clothing and that protection within the NHS is provided by the use of disposable aprons. Surprisingly some healthcare workers and qualified nurses were not discarding aprons after patient contact, not only is this bad practice but it increases the risk of cross infection between patients. Babb et al (1983) within Candlin J, Stark S (2005) article found that “although micro-organisms can survive for varying lengths of time and adhere to plastic aprons, they do not multiply and are difficult to redistribute”.
