Germ Sensor | Standard Prevention and Hand Hygiene

With the development of medicine and science, more and more attention has been paid to the problem of nosocomial infection, which has become a prominent public health problem. As we all know, there are many factors that cause virus transmission and infection in the hospital. Hand hygiene is a very important measure to prevent and control hospital infection and must be highly valued by medical staff.

Hand is one of the main ways of spread of germs

Foreign reports: 80% of hospital infections caused by the hand

Domestic statistics: 30% of nosocomial infections transmitted by hand

Hand hygiene has always been the most economical, convenient and effective preventive and control virus infection. At a recent academic conference, Professor Hu Guoqing, chief physician of Zhejiang Provincial CDC, explained the importance of standard prevention and hand hygiene through "standard prevention and hand hygiene".

【1】 What is standard prevention?

Standard prevention was proposed by the CDC in 1995 in the United States and implemented in the whole of the United States in 1996. China introduced it in 1999 and stipulated in the Norm of Nosocomial Infection Management that the hospital should, on the basis of implementing standard prevention and according to different situations, Infection patients to take appropriate isolation measures. Standard prevention for the patient diagnosis, treatment, nursing operation of the whole process for each patient.

[2] the role of standard prevention

SARS outbreak in 2003, Ebola outbreak in 2014-2015, MERS outbreak in South Korea in 2015, AIDS and hepatitis B and hepatitis C outbreak. Standard precaution is always on the prevention and control of epidemic situation.

Standard prevention avoids more infections and can avoid major nosocomial events.

[3] The standard prevention of the core idea: treat everyone equally, two-way protection, three isolation

1. Non-discriminatory: all patients with blood, body fluids, secretions, excretions are contagious;

Bi-directional protection: medical staff between patients;

3. Three kinds of isolation: for the three modes of communication between doctors and patients. According to the route of transmission on the basis of the standard precautionary approach to contact isolation, foam isolation, air isolation.

[4] How to implement the eight standard preventive measures?

Hand hygiene

Wear gloves

3. Proper use of masks, goggles and face masks

4. Real-time wear gown, protective clothing, shoe cover

5. Treatment of contaminated medical equipment or articles

6 Resuscitation sites may require resuscitation with a simple breathing bladder (resuscitation bag) or other ventilation instead of mouth-to-mouth resuscitation methods

7. Medical Waste According to the "Medical Waste Management Regulations" and its relevant laws and regulations for harmless disposal

8. Environment, the surface of objects, clothing, food and beverage disinfection

[5] hand hygiene

Hand hygiene is the simplest, most economical and effective measure for nosocomial infection control, which is the basis of the hospital's control work. Since 2009, the WHO initiative has launched World Handwashing Day on May 5 each year, which aims to emphasize hand hygiene of medical staff and reduce the incidence of iatrogenic infection during medical care. This year's World Hand Day theme is "to stop the fight against antibiotics, in your hands and I."

[6] How to implement hand hygiene?

Medical staff hand hygiene requirements:

Health hand disinfection of medical staff after the surface of the total number of colonies ≤ 10cfu / c ㎡

Surgical hand disinfection of medical staff surface colony total ≤ 5cfu / c ㎡

Only on the operating table before surgical disinfection it?

In addition to the operating table, PICC, endoscopic center, hemodialysis fistula need surgical disinfection

Is surgical hand disinfection necessary?

WHO guidelines: Use of brushes not recommended as a surgical hand sanitizer (IB)

AORN: Using a brush as a surgical hand sanitizer to reduce the number of colonies is not necessary

Do you have to use a sterile hand towel after disinfecting the hand?

The United States use no hand disinfection generally do not dry hands. Hand towels can also be used if the paper towels meet the requirements.

WHO recommendations for disinfection of surgical staff:

It is advisable to prepare the hand before wearing sterile gloves or by rubbing with an antibacterial soap solution and running water or with a hand sanitizer.

Under what circumstances choose to wash your hands?

Do not wash hands with contaminated soap or soap when hands have contaminants or spore contamination.

What kind of dry hand should be chosen after hand washing?

Disposable tissue is the best way to dry your hands.

Why promote instant dry disinfectant?

Fast hand (20-30 seconds) when not spotting contaminants, easy to accept, good compliance. Press a tap to dry.

Why do we hand hygiene is not high compliance?

The reasons are: inadequate hand hygiene supplies, hand hygiene facilities are not standardized, hand hygiene is not standardized, there is not enough awareness of medical staff and management attention is not enough and so on. In 2014, the passing rate of hand hygiene facilities for flight check in the country was less than 60%, and qualified hand hygiene facilities were also necessary for improving hand hygiene compliance.

Multiple strategies for improving hand hygiene in WHO

a: change the way, nursing time using alcohol hand rub

b: The supply of safe and sustainable soap, paper towels, flowing water. Nurses station non-taps, hand soap, paper towels and so on

Training and Education: Various training methods are provided to different employees such as working medical staff, new employees, cleaning workers and care workers according to local conditions and at different occasions, lectures, lectures and symposiums.

Assessment and feedback: Assessment and feedback on training and practice

Workplace tips: reminders and publicity anywhere, such as the pool next to the elevator, computer screensavers remind anytime, anywhere

Medical Institutional Safety: Creating a Safe Environment, Patient-Centered, and Hand-Health Priority. From management to individuals, raise awareness and collaborate with patients.

【7】 Foreign multi-drug resistant bacteria to deal with prevention and control measures

1. Hand hygiene and environmental cleaning and disinfection

2. Isolate and reduce equipment common

3. Comprehensive prevention of hospital infection

4. Active monitoring and training

5. Chlorhexidine bath

6. Rational use of anti-bacterial drugs

【8】 Use of protective equipment and requirements

1 wear gloves requirements

Wear gloves when touching the patient's blood, body fluids, secretions, excretions, vomit and contaminated items.

Between the two patients must be replaced gloves, glove replacement hand hygiene, gloves can not replace hand hygiene.

2 Proper use of masks

Gauze masks can not be used for medical protection. Disposable medical masks for general protection. Medical surgical mask used to spray isolated. N95 ≠ medical protective masks.

3 Goggles and face shields: Use goggles or face shields in the following situations:

A) In the treatment, nursing operations, may occur in patients with blood, body fluids, secretions and other splashes.

B) close contact with the spread of infectious droplets of patients.

C) Patients with respiratory diseases tracheotomy, endotracheal intubation and other close operations, may occur in patients with blood, body fluids, secretions splashing, should use a full-size protective mask.

Before wearing should check for damage, wear devices without slack.

4 gown: the following conditions should wear gowns

A) Exposure to contact-infected patients with infectious diseases such as infectious patients, patients with multiple drug-resistant bacteria, etc.

B) In the case of patient's protective isolation, such as large-area burned patients, patients with bone marrow transplantation and other patients during treatment and care.

C) may be affected by the patient's blood, body fluids, secretions, excretion splashed.

5 protective clothing: waterproof impermeable

Should be consistent with GB19082-2009 "medical disposable protective clothing technical requirements", the choice should pay attention to the overall protective clothing protective clothing (Type-3B) above, at the same time check the artificial blood penetration test, blood-borne pathogen penetration test, resistance Wet bacterial penetration test, resistance to dry microbial penetration test grade meets the requirements. Choose protective clothing need to consider whether the thumb to ensure that the cuff can cross the inner glove.

【9】 Why should implement three kinds of isolation protection?

Isolation based on route of transmission is intended for the prevention of infectious or suspicious infectious or pathogenic bacterial infections of epidemiological significance. Isolation measures other than standard precautions must be prevented by cutting off the route of transmission. . Isolation protection includes contact isolation, foam isolation, air isolation. They can work together to provide isolation protection against the spread of infectious diseases in a variety of ways.

[10] three kinds of isolation protection of specific measures?

1. Air isolation:

For tuberculosis, measles, chickenpox. Isolation measures: Negative pressure wards, medical respirators (no need to wear medical respirators for measles and chickenpox), tertiary protection, hand hygiene and gloves, wear gowns to carry out spitting diagnosis and treatment operations, and not allow patients to go out At any time disinfection and terminal disinfection, air disinfection.

2. Droplet isolation:

For most respiratory diseases, H1N1, H9N9, SARS and so on. Respiratory mucosal secretions, spread no more than 1 meter. Isolation measures: Isolation of wards, medical surgical masks, hand hygiene and gloves, gowns (with isolation clothing when touching the patient within 1 meter), limiting the patient's out-going activities, wearing a surgical mask when going out, disinfecting and terminating at any time.

3. Contact isolation:

For intestinal infections, multiple drug-resistant bacterial infections, skin infections. Spread through direct or indirect contact, such as hands / gloves, environmental surfaces, medical supplies / equipment, etc. Isolation: Isolation wards, medical surgical masks, hand hygiene and gloves, gowns (expect your clothes to come into contact with the patient or on the surface of the environment, or to care for patients with diarrhea and incontinence, or oozing of infected wounds Contact wear gown), limit the scope of patient out activities, wearing a surgical mask when going out, at any time disinfection and terminal disinfection.

summary:

Professor Hu suggested: medical institutions and medical staff should follow the "clean hands, health care (2015-2018)" special work guidance program requirements (medical and health institutions hand hygiene facilities and equipment configuration pass rate ≥ 80%, key departments Hand hygiene facilities and supplies configuration pass rate of 100%; medical and health institutions medical staff hand hygiene training coverage of 100%; hand hygiene knowledge awareness rate of ≥ 90%; medical and health institutions medical staff hand hygiene compliance rate of 60% Rate of ≥ 75%; key departments compliance and correct rate reached 75% and 90% respectively), to ensure the quality of medical care and patient safety.
