The current health care system

Health Care system can take credit for improving the life span of people through advances in medical technology, science, and the pharmaceutical industry in relation with the issues related to cost, quality and access to health care

Three trends that affecting health care:

Cost

Access

Quality

Trends affecting the health care system:

Demographic trends

Social trends

Economic trends

Health workforce trends

Technology trends

Primary health care (PHC)

The PHC movement officially began in 1977 .

Is essential health care; based on practical, scientifically sound, and socially acceptable method and technology; universally accessible to all in the community through their full participation; at an affordable cost; and geared toward self-reliance and self-determination (WHO & UNICEF, 1978).

The setting for primary health care is within all communities of country and permeates all aspects of society.

The PHC workforce:

Team members include many professionals such as generalist and public health physician, nurses, dentists, pharmacists, optometrists, nutritionists, community outreach workers, mental health counselors, and other allied health professionals, and community members are considered to the team.

Self-care and self management in the health and social welfare aspects of daily life.

People are educated to use their knowledge, attitudes, and skills in activities that improve health for themselves, their families, and their neighbors.

The desired outcome from the PHC strategy is individual, family and community self reliance and competence.

The PHC encourage:

Principles of Primary Health Care

Equitable distribution

Health services should be shared or distributed equally to all areas irrespective of city (urban/village (rural), rich/poor, caste/ color etc

Accessibility - People should have reasonable access to essential health services with no financial or geographical barriers.


Community participation

Involving individual, family and community in promotion of their own health is an essential aspect of PHC.

The public should be encouraged to participate in planning and making decisions about their own health care.


Inter-sectoral coordination

Alone, health sector or department can not work out for the benefit of the community health. E.g. Agricultural, animal husbandry, food, industry, education, housing, public works, communication. To get all of these sectors to work for the common goal like health care system strong political involvement is needed.

Professionals from various sectors, including the health sector, work independently with community members to promote the health of the community.


Appropriate technology:

The meaning of the term “Appropriate technology" is : Scientifically sound Adaptable to local needs and acceptable to those who

uses Maintained by people Resources that community and country can afford

Focus on prevention

The focus of care should be on prevention rather than cure

Elements/ essential components of primary health care (WHO & UNICEF, 1978)

1. Education concerning prevailing health problems and methods of preventing and controlling them

2. Promotion of food supply and proper nutrition

3. An adequate supply of safe water and basic sanitation

4. Maternal and child health care, including family planning

5. Immunization against the major infectious diseases

6. Prevention and control of locally endemic diseases

7. Appropriate treatment of common diseases and injuries

8. Provision of essential drugs

PHC – element No.1Health education

Education for promotion of health and prevention of

disease is an essential factor mentioned in Alma-Ata declaration

The individual should decide to be healthily or not , to accept health measures and to create a healthily environment .

PHC – element No.2Promotion of food supply and proper nutrition

Nutrition is a basic factor influencing the quality of human life.

Under nutrition is still one of the greatest health hazards. Child and maternal malnutrition is widespread.

Community health workers should be responsible for the promotion of better nutrition.

Correction of faulty feeding practices and prevention infectious diseases which are nutrition – related , eg. Diarrhea

PHC – element No.3An adequate supply of safe water and basic sanitation

The main objectives of this PHC elements are to prevent diseases and improve the quality of life and well-being of the population by promoting personal and community hygiene

Ensuring the availability of safe water supply and sanitation facilities through self reliant, community action and also by associating water supply and sanitation with other health and/or development programs

PHC – element No.4Maternal and child health care, including family planning

Maternal and child health care (MCH/FP) as part of PHC aims at promoting and protecting the health of children and women of childbearing age

So that all children have the possibility for healthily growth and development

and so that reproductive life of women is compatible with a state of health and well being

PHC – element No.4Maternal and child health care, including family planning

MCH/FP (Maternal and Child Health/Family Planning) care includes at five main functions

Antenatal care Delivery care Post natal care Child care Family planning care

PHC – element No.5Immunization against the major infectious diseases

Immunization programs seeks to reduce morbidity and mortality by providing immunization against the major killers of children.

In the developing world, priority is usually given to the following diseases:

Diphtheria, Whooping cough, Tetanus Measles, Rubella, Poliomyelitis Tuberculosis, Hepatitis B Tetanus immunization for pregnant mothers

PHC – element No.6Prevention and control of locally endemic diseases

Malaria Malaria remains one of the most important

widespread endemic diseases. There are about 120 -150 million cases annually

The objectives may range from reduction of mortality in some areas to full-scale country wide malaria eradication

Hypertension High blood pressure is another health problem and

form 8 – 18 % of adults in most countries both developed and developing, have pressures above 160mm/Hg systolic and 95mm/Hg diastolic.

The long term objectives are;

-To prevent hypertension if possible

-To reduce the mortality and morbidity due the

consequences of high blood pressure

PHC – element No.6Prevention and control of locally endemic diseases

PHC – element No.7: Appropriate treatment of common diseases and injuries

Accidents are among the highest causes of death in most countries

The aims, therefore must be not only to provide first aid on the spot and adequate treatment at the appropriate level of care, but also to prevent the occur of similar accidents in the future and to provide program for active rehabilitation of disabled persons, children as well as adults

Three types of home accidents have been chosen as examples; Cuts, Burn, and Poisoning

PHC – element No.7: Appropriate treatment of common diseases and injuries

PHC – element No.8Provision of essential drug

The provision of essential drugs aims at making these drugs available to the users of the health systems at all levels of PHC, all over the country, at all times by instituting an efficient system of drug acquisition, storage, distribution and utilization

Aims of primary health care

•Promotion of health

•Prevention of diseases(primary, secondary and tertiary levels)


Promotion of health

Action related to lifestyles and choices that maintain or enhance a populations health

(WHO) "Any combination of educational, organizational, economic, and environmental supports for behavior and conditions of living conductive to health".

Health promotion includes all efforts that seek to move people closer to optimal well-being or higher levels of wellness. Nursing, in particular, has a social mandate for engaging in health promotion.


Promotion of health

The goal of health promotion is to raise levels of wellness for individuals, families, populations, and communities.

Community health efforts accomplish this goal through a three-pronged effort to:1. Increase the span of healthy life for all citizens2. Reduce health disparities among population groups3. Achieve access to preventive services for everyone


Promotion of health

Health promotion programs and activities include many forms of health education—for example,

Physical activity and fitness. Nutrition. Tobacco use.Teaching the dangers of alcohol and drug use.Family planningMental health and mental disordersViolent and abusive behaviorEducational and community-based programs


Prevention of diseases

Nursing care oriented to health promotion, wellness and illness prevention can be understood in terms of health activities on primary, secondary and tertiary levels. Prevention means anticipating and averting problems or discovering them as early as possible to minimize potential disability and impairment


Prevention of diseases-Primary Prevention

Any effort done before or to prevent the problem to occur.

Primary prevention obviates the occurrence of a health problem; it includes measures taken to keep illness or injuries from occurring. It is applied to a generally healthy population and precedes disease or dysfunction.

It can be provided to an individuals or to general population, or it can focus on individuals at risk for developing specific diseases. Wellness activities are synonymous with the activities identified for primary prevention.


Prevention of diseases-Secondary Prevention

It focuses on individuals who are experiencing health problems or illness and who are at risk for developing complications or worsening conditions.



Early diagnosis and prompt treatment:Involves efforts to detect and treat existing health problems at the earliest possible stage when disease or impairment already exist.

Hypertension and cholesterol screening programs in many communities help to identify high-risk individuals and encourage early treatment to prevent heart attacks or stroke.

Other examples are teaching breast and testicular self-examination, encouraging regular mammograms and Pap smears for early detection of possible cancer



Disability limitation Secondary prevention attempts to discover a health

problem at a point when intervention may lead to its control or eradication.

This is the goal behind testing of water and soil samples for contaminants and hazardous chemicals in the field of community environmental health.

It also prompts community health nurses to watch for early signs of child abuse in a family, emotional disturbances in a group of alcohol and drug abuse among adolescents


Prevention of diseases- tertiary Prevention

Involves efforts to reduce disability and, as much as possible, restore function.

This focuses on helping people manage complicated, long-term health problems such as diabetes, heart disease, cancer and chronic musculoskeletal pain. The goals include preventing further physical deterioration and maximizing quality of life. For example:cardiac or stroke rehabilitation programschronic pain management programspatient support groups

PRIMARY HEALTH CARE IN Saudi Arabia

Primary health care (PHC) is defined by the World Health Organization (WHO) as essential health care made universally accessible to individuals and families in the community by means acceptable to them through their full participation and at a cost the community and the country can afford

Saudi Arabia started implementing this approach in 1980 by the Ministry of Health (MOH).

PRIMARY HEALTH CARE IN Saudi Arabia

The MOH provides primary health care (PHC) services through a network of health care centers throughout the kingdom.

It also adopts the referral system which provides curative care for all members of society from the level of general practitioners at health centers to advanced technology specialist curative services through a broad base of general and specialist hospitals

Health For All

In 1977, it was decide in the world health assembly to lunch a movement known as "health for all by the year 2000".

The fundamental principle of HFA strategy is equity , that is an equal health status for people and countries, ensured by an equitable distribution of health resources.

The member countries of WHO at the World Health Assembly defined health for all as:

Attainment of a level of health that will enable every individual to lead as socially and economically productive life

Health For All

In 1981, after identifying the goal of HFA and the PHC strategy for realizing that goal, the WHO established global indictors for monitoring and evaluating the achievement of HFA.

These indicators are grouped into four categories. Health PoliciesSocial and Economic DevelopmentProvision of Health CareHealth Status.

Health Indicator

A health indicator is a characteristic of an individual, population, or environment which is subject to measurement (directly or indirectly) and can be used to describe one or more aspects of the health of an individual or population (quality, quantity and time). (WHO, 1998)

General Indicator-related definitions

Proportion: The relation of a subgroup to the entire group; that is the subgroup divided by the entire group.

Rate: The frequency of events in a population during a specified time period (usually a year) divided by the population ‘at risk’ of the event occurring during that time period.

Or a rate is: A statistical measures expressing the proportion of persons with a given health problem among a population at risk.


Ratio: The relation of one population subgroup to the total population or to another subgroup; that is, one subgroup divided by another.

Which is simply the comparison of one number with another

A ratio: is often used to compare one at-risk population with another.

The number of females: The number of males


Incidence and Prevalence Rates

Incidence: Refers to the rate at which a specific disease develops in a population. An incidence rate is the number of new cases of an illness or injury that occurs in a specific time.

Prevalence: The number of cases in a defined population at a specified point in time.Prevalence: measures all of the existing cases at a given point of time.Prevalence includes the incidence (new cases) plus all of the existing cases.


Life expectancy at birth: The average number of additional years a person could expect to live if current mortality trends were to continue for the rest of that person’s life.

Maternal mortality ratio: The number of women who die as a result of childbearing or within 42 days of termination of pregnancy in one year, per 100 000 live births during that year.
