Great Sanitary Awakening (1800s-1900s)Growth in scientific knowledgeHumanitarian idealsConnection between povertyand diseaseWater supply , sewage removalMonitor community health status
15anupama krishnan vpsv ayurveda collegee kottakkal
The great sanitary awakening is the birth of modern public health:Great strides in scientific knowledge to help understand the origin and treatment of disease.Interest in humanitarian idealsAcknowledgement of the connection between poverty and disease.Even today, poverty is the single best predictor of poor health.Returning to what the Romans had figured out, new infrastructure for clean water and sewage removal Birth of a system to monitor the health status of communities
BackgroundAshton (1990) describes four phases of the development of modern-day public health:An initial environmentally-focused phase which addressed infectious diseases related to urbanization, poverty and squalor. This phase lasted from the 1840s to the late 19th century.A second phase of personal preventive medical services related to immunization, family hygiene, health education and family planning which began with the development of vaccines in the late 19th century and lasted until the 1930s.A therapeutic era that began with the development of insulin and antibiotics in the 1930s and persists until today. Its focus is on improving population health through the provision of organized medical services deploying effective therapeutic technologies.A recognition that the environment is also social, economic and psychological and that healthy public policy (Hancock, 1982) is an appropriate part of this new public health.
Sanitary revolutionClean water; water treatmentFood inspectionSoaps, disinfectants, pharmaceuticalsPersonal hygiene (bathing)Public works departments; garbage collection, landfills, street cleaningPublic health departments and regulation16anupama krishnan vpsv ayurveda collegee kottakkal
The death rate in children drops and the average life span increases over the years from less than 40 to 74.
By 1900 -- Greater acceptance of the germ theory of disease begins to shift the job of garbage removal from health departments to public works departments. Health officers, it is felt, should spend their time battling infectious diseases, not cleaning up "public nuisances" such as garbage.

Article 246 of Constitution of India21anupama krishnan vpsv ayurveda collegee kottakkal
Coverage
2.6 billion people lack access to improved sanitationTwo thirds of whom live in Asia and Saharan Africa More than half live in India, lack even an unimproved sanitation facility and must defecate in the open22anupama krishnan vpsv ayurveda collegee kottakkal
Consequence Every year, 1.5 million children die due to diarrhea caused by combined effects of inadequate sanitation, unsafe water supply, and poor personal hygiene Lack of sanitation contributes to about 10% of the global disease burden
23anupama krishnan vpsv ayurveda collegee kottakkal
1 billion people regularly defecate in the open (United Nations) Dramatic consequences on the human health, dignity and security One out of three women around the world lack access to safe toilets24anupama krishnan vpsv ayurveda collegee kottakkal

105 This iceberg graphically represents colonization versus infection. Those patients that are infected with an organism represent just the tip of the iceberg of patients that are colonized or infected. Just because a patient is not infected, or showing signs of infection, does not mean that they do not carry organisms that could be transferred to another patient if proper hand hygiene and other infection control precautions are not taken.
Bacteria that colonize patients can be transmitted from one patient to another by the hands of healthcare workers
Bacteria can be transmitted even if the patient is not infected

Effective Hand HygieneAlcohol-based hand rub (ABHR)Should contain 70 90% alcoholTakes less time than hand washingMore effective than hand washing with soap and water when hands are not visibly soiled132anupama krishnan vpsv ayurveda collegee kottakkal
Common types of alcohols used include ethanol,isopropanol or combinations Antimicrobial action of ethanol and isopropanol similarEthanol has greater activity against viruses than isopropanolWHO recommended formulations contain either 75% v/v isopropanol, or 80% v/v ethanol
133anupama krishnan vpsv ayurveda collegee kottakkal
Mechanical rubbing action is important to kill transient microorganisms Less drying to hands than soap and water
134anupama krishnan vpsv ayurveda collegee kottakkal
Efficacy of ABHRDepends on the quality of product, the amount of product used, timeSpent rubbing ,hand surface rubbedNOT be used with water, water willDilute alcohol and reduce its effectivenessABHR should NOT used immediately after hand washing with soap and water
135anupama krishnan vpsv ayurveda collegee kottakkal
Hand washing with soap and running waterPreferred when hands are visibly soiled alcohol is inhibited by organic matterMechanical action of washing, rinsing and drying removes most transient microorganisms
136anupama krishnan vpsv ayurveda collegee kottakkal
Efficacy of Soaps
Plain soaps act on hands by emulsifying dirt and organic substances (e.g., blood, mucous), which are then flushed away with rinsing
Atleast 15 seconds of lathering with soap is required to remove transient flora
137anupama krishnan vpsv ayurveda collegee kottakkal
Antimicrobial agents in plain soaps are only present as a preservative.137
Antimicrobial soaps have residual antimicrobial activity Not deactivated by presence of organic materialAntimicrobial soap may be considered for use in critical care areas138anupama krishnan vpsv ayurveda collegee kottakkal

What is the single most important reason for healthcare workers to practice good hand hygiene?
To remove visible soiling from handsTo prevent transfer of bacteria from the home to the hospitalTo prevent transfer of bacteria from the hospital to the home To prevent infections that patients acquire in the hospital184anupama krishnan vpsv ayurveda collegee kottakkal
184 The correct answer is #4, to prevent infections that patients acquire in the hospital. All answers are good reasons to practice good hand hygiene. Improved adherence to hand hygiene has been shown to terminate outbreaks in healthcare facilities, reduce the transmission of antimicrobial resistant organisms, and reduce overall infection rates.
Healthcare-associated organisms are commonly resistant to alcohol.Strongly agreeAgreeDont knowDisagreeStrongly disagree185anupama krishnan vpsv ayurveda collegee kottakkal
185 The correct answer is disagree, or strongly disagree. To date, there have been no reported cases of organisms resistant to alcohol.
When a healthcare worker touches a patient who is COLONIZED, but not infected with resistant organism HCWs hands are a source for spreading resistant organisms to other patients.Strongly agreeAgreeDont knowDisagreeStrongly disagree186anupama krishnan vpsv ayurveda collegee kottakkal

When a healthcare worker touches a patient who is COLONIZED, but not infected with resistant organisms the HCWs hands are a source for spreading resistant organisms to other patients.Strongly agreeAgreeDont knowDisagreeStrongly disagree187anupama krishnan vpsv ayurveda collegee kottakkal
187 The correct answer is strongly agree or agree. Patients that are colonized but not infected with bacteria can still contaminate the hands of healthcare workers, who can then spread the organisms to other patients unless proper hand hygiene is practiced.
Use of artificial nails by healthcare workers poses no risk to patients.Strongly agreeAgreeDont knowDisagreeStrongly disagree
188anupama krishnan vpsv ayurveda collegee kottakkal
188
Use of artificial nails by healthcare workers poses no risk to patients.Strongly agreeAgreeDont knowDisagreeStrongly disagree
189anupama krishnan vpsv ayurveda collegee kottakkal
189 The correct answer is disagree, or strongly disagree. Even after careful handwashing, healthcare workers often harbor substantial numbers of potential pathogens in the subungual spaces. A growing body of evidence suggests that wearing artificial nails may contribute to transmission of certain healthcare-associated pathogens. Healthcare workers who wear artificial nails are more likely to harbor gram-negative pathogens on their fingertips than are those who have natural nails, both before and after handwashing.
Glove use for all patient care contacts is a useful strategy for reducing risk of transmission of organisms.Strongly agreeAgreeDont knowDisagreeStrongly disagree
190anupama krishnan vpsv ayurveda collegee kottakkal
190
Glove use for all patient care contacts is a useful strategy for reducing risk of transmission of organisms.Strongly agreeAgreeDont knowDisagreeStrongly disagree
191anupama krishnan vpsv ayurveda collegee kottakkal
191 The correct answer is strongly agree, or agree. For many years, authorities have recommended that healthcare workers wear gloves for three reasons: to reduce the risk of healthcare workers acquiring infections from patients, to prevent flora from being transmitted from healthcare workers to patients, and to reduce contamination of the hands of healthcare workers by flora that can be transmitted from one patient to another.
It is acceptable for healthcare workers to supply their own lotions to relieve dryness of hands in the hospital.Strongly agreeAgreeDont knowDisagreeStrongly disagree192anupama krishnan vpsv ayurveda collegee kottakkal
192 The correct response would be to either disagree, or strongly disagree. According to the HICPAC hand hygiene guideline, only hospital-supplied lotions should be used, as some lotions may affect the integrity of latex gloves and the efficacy of antimicrobial soaps or alcohol-based handrubs used in the facility.
Hygiene
193anupama krishnan vpsv ayurveda collegee kottakkal
Hygiene is healthy habits that include bathing, keeping the mouth clean, keeping the skin protected from the sun and washing hands frequentlyHygei GreekIndustrial revolution 1750- 1850
194anupama krishnan vpsv ayurveda collegee kottakkal
Hygiene and BehaviorHygiene is a key factor in reducing risk of sanitation-related diseasesHygiene behaviorMaking behavior changes requires actions Information about how and why personal and community behaviors will reduce disease transmission risks Encouragement to make positive changes in their hygiene behavior Hygiene education is essential to achieve hygiene behavior change

However, for behavioral change to occur and be sustained there is a need to continue hygiene promotion until the new behavior has become entrenched199anupama krishnan vpsv ayurveda collegee kottakkal
Hygiene Promotion Key PrinciplesTarget a small number of risk practicesTarget specific audiences Identify the motives for changed behavior Hygiene messages need to be positive Identify appropriate channels of communication Decide on a cost-effective mix of channels Hygiene promotion needs to be carefully planned, executed, monitored and evaluated.

Washing HandsOne of the most effective behaviors to prevent diarrhoea, roundworm and whipworm. Rarely done at the most crucial times and rarely done most effectively (with soap). (Is soap really needed?)Hands get most dangerously contaminated fron human faces and soil (possibly containing worm eggs). Crucial times for handwashing to reduce transmissions are: after defecation and after contact with childrens faeces before handling food and after handling high risk food such as raw meatbefore eating and before feeding childrenbefore handling water. Effective handwashing requires thorough rubbing of the hands while using soap and sufficient water to rinse it off. If soap is not available, ash or earth is nearly as effectiveWater alone is effective, especially of water is clean223anupama krishnan vpsv ayurveda collegee kottakkal
