Community Health Nursing: Definition, Principles, Qualities of a Nurse, and Scope

1. Definition of Community Health Nursing

• American Nurses Association (ANA): "A synthesis of nursing practice and public health practice applied to promote and protect the health of populations... with the goal of preserving, protecting, and improving the health of all people through collective or social action."
• American Public Health Association (APHA): Community health nursing is directed toward the health of the total community. It is not limited to any particular age group or diagnosis, and it includes all people regardless of race, class, or social standing.
• Park's Preventive and Social Medicine describes the evolution: Public health nursing was "a direct offshoot" of the health promotional concept (1920-1960), when it was realized that personal health services - including maternal and child health, school health, and mental health - required nurses working beyond clinical walls and into communities.
• The term community health nurse emerged in the 1960s to describe nurses working with individuals in community settings (home health care, case management). By the 21st century, the focus shifted back to "public health nursing" - emphasizing population-level work within communities, not just care setting.

2. Principles of Community Health Nursing

• Continuity of care - providing ongoing rather than episodic care
• Evidence-based practice - grounding all decisions in research
• Empowerment - building the capacity of individuals, families, and communities for self-care
• Partnership - community participation in planning and evaluation of health services

Question 2(a) - Detailed Answer

Define Non-Communicable Disease. Explain Epidemiology of Cancer and National Tobacco Control Programme.

PART 1: Non-Communicable Diseases (NCDs) - Definition

WHO Classification of Major NCDs:

Key Characteristics of NCDs:

1. Non-infectious - not transmitted by contact, droplets, or vectors
2. Chronic and long-lasting - persist for years or decades
3. Multifactorial etiology - caused by multiple interacting risk factors
4. Largely preventable - through lifestyle modifications and risk factor control
5. Major risk factors: Tobacco use, Harmful alcohol use, Unhealthy diet, Physical inactivity, Air pollution

NCD Risk Factor Statistics (Global):

• Tobacco: Nearly 7 million deaths/year; causes 71% of lung cancer, 42% of chronic respiratory disease, 10% of CVD
• Physical inactivity: ~1.6 million deaths/year; 20-30% increased all-cause mortality
• Harmful alcohol: ~3.3 million deaths/year (5.9% of all deaths globally)
• Raised blood pressure: 9.4 million deaths/year (12.8% of all deaths) (Park's Preventive & Social Medicine, p. 413)

PART 2: Epidemiology of Cancer

Definition of Cancer

1. Abnormal uncontrolled growth of cells
2. Ability to invade adjacent tissues and distant organs (metastasis)
3. Death of the patient if the tumour progresses beyond a treatable stage

Types/Categories of Cancer:

Global Burden of Cancer (2020)

• New cases: 19.29 million
• Deaths: 9.96 million
• Most common cancer diagnosed: Breast > Lung > Prostate > Colon > Stomach
• Leading cause of cancer death: Lung > Liver > Stomach > Breast
• Risk of developing cancer before age 75: 20.4% (Males 22.6%, Females 18.6%)

India - Cancer Statistics (2020)

• New cases: 13,24,413
• Deaths: 8,51,678
• 5-year prevalent cases: 27,20,251
• Top cancers in Males: Lip/oral cavity, Lung, Stomach, Colorectum, Oesophagus
• Top cancers in Females: Breast, Cervix uteri, Ovary, Lip/oral cavity, Colorectum
• Cancer in males is mostly tobacco-related; cervical cancer in females is linked to poor genital hygiene and HPV

Causes/Etiology of Cancer (Multifactorial)

1. Environmental Factors (responsible for 80-90% of cancers)

2. Genetic Factors

• Retinoblastoma (hereditary), Down syndrome (leukemia risk elevated)

3. Host Factors

• Age, sex, race, immune status, nutritional state

Cancer Control Strategies (5 Components):

• Tobacco cessation programs
• Dietary modification
• Hepatitis B vaccination (prevents liver cancer)
• HPV vaccination (prevents cervical cancer)
• Limiting occupational exposures
• Sun protection

• Hospital-based registries - treat patients in that institution
• Population-based registries - cover entire geographic area (ideal size: 2-7 million people)
• India's National Cancer Registry Programme (NCRP) by ICMR - 28 population-based + 5 hospital-based registries

• Screening = "search for unrecognized malignancy by means of rapidly applied tests"
• Cervical cancer: Pap smear, VIA (Visual Inspection with Acetic acid)
• Breast cancer: Breast self-examination (BSE), mammography
• Oral cancer: Visual inspection

• Surgery, radiotherapy, chemotherapy (multi-modality approach)
• Pain management for advanced cases (WHO guidelines)

• Physical, psychological, and social rehabilitation of cancer survivors

PART 3: National Tobacco Control Programme (NTCP)

Background:

1. Implement tobacco control laws
2. Raise awareness about harmful effects of tobacco
3. Fulfill obligations under WHO - Framework Convention on Tobacco Control (FCTC)

Coverage:

• Pilot phase started in 2007-08 in 16 districts across 9 states
• Now covers 108 districts in 31 states

Legal Framework - COTPA 2003:

1. Prohibition of smoking in public places (effective 2nd October 2008)
2. Prohibition of direct and indirect advertisement of tobacco products
3. Prohibition of sale to persons below 18 years
4. Prohibition of sale near educational institutions
5. Mandatory statutory/pictorial health warnings on tobacco packs (85% of principal display area from April 2016)
6. Mandatory display of tar and nicotine content on packs

9 Main Components of NTCP:

Role of CHC (Community Health Centre) Under NTCP:

• Health education and IEC activities on harmful effects of tobacco and secondhand smoke
• Promoting quitting of tobacco in the community
• Brief advice to all smokers and tobacco users
• Making CHC premises tobacco free and displaying mandatory signages

• Setting up a Tobacco Cessation Clinic by training counselors in cessation
