SHORT ESSAY 3: 'Targeted Interventions' in HIV Control
Definition
Targeted Interventions (TIs) are focused HIV prevention and care programmes directed specifically at High Risk Groups (HRGs) who are most vulnerable to HIV infection and most likely to transmit it to the general population.
Rationale
- HIV transmission is not uniform - it clusters in specific populations
- High Risk Groups serve as a "bridge" to the general population
- Targeting these groups gives maximum impact per rupee spent
High Risk Groups (HRGs) under NACP (National AIDS Control Programme)
| Group | Abbreviation |
|---|
| Female Sex Workers | FSWs |
| Men who have Sex with Men | MSM |
| Intravenous Drug Users | IDUs |
| Truckers | TRs |
| Migrants | |
| Bridge populations | |
Components of Targeted Interventions
1. Outreach:
- Peer-led outreach to reach HRGs in their natural settings
- Building trust, distributing Information, Education and Communication (IEC) materials
- Condom promotion and distribution
2. STI Services:
- Diagnosis and treatment of Sexually Transmitted Infections (STIs)
- STIs increase HIV transmission risk 3-10 times
- Syndromic management of STIs
3. Behaviour Change Communication (BCC):
- Promoting consistent condom use
- Reducing number of sexual partners
- Needle/syringe exchange for IDUs
4. Needle Syringe Programme (NSP)/Opioid Substitution Therapy (OST):
- Clean needles and syringes for IDUs
- Buprenorphine/methadone substitution therapy
5. HIV Testing and Counselling:
- Integrated Counselling and Testing Centres (ICTCs)
- Regular HIV testing for HRGs
6. Linkage to Care:
- Referral to ART centres for HIV-positive individuals
- Follow-up and retention in care
Implementation in India (NACP)
- Implemented under National AIDS Control Programme (NACP)
- NACO (National AIDS Control Organization) oversees
- State AIDS Control Societies (SACS) implement at state level
- NGOs are the primary implementing agencies
- Scaling up TIs was a key strategy in NACP-III and NACP-IV
SHORT ESSAY 4: Yellow Fever Vaccine
Yellow Fever - Brief Overview
- Causative agent: Flavivirus fibricus (Group B arbovirus, Togavirus family)
- Vector: Aedes aegypti (urban) and forest mosquitoes (jungle)
- Reservoir: Monkeys (jungle), Man (urban)
- Endemic zones: 47 countries in Africa and Latin America; ~900 million at risk
The 17D Vaccine
Nature
- Live attenuated vaccine prepared from a non-virulent 17D strain

Important Drug Interaction
- Cholera vaccine and yellow fever vaccine interfere with each other
- Should be given 3 weeks or more apart
International Health Regulations
- Yellow fever vaccination certificate required by many countries for travelers
- Compulsory vaccination for travelers going to/from endemic areas
- Vaccination must be recorded in International Certificate of Vaccination (Yellow Card)
SHORT ESSAY 5: Levels of Health Care
Introduction
Health services are organized at three levels, each supported by a higher level to which patients are referred. This is also called the "Referral system".
Three Levels of Health Care
(a) Primary Health Care (First Level)
- First level of contact between individual and health system
- Provides "essential" health care - the most basic and fundamental care
- A majority of health complaints can be satisfactorily dealt with at this level
- Closest to the people - community-based
- In India: Primary Health Centres (PHCs) and Sub-Centres (SCs)
- Services: Preventive, promotive, curative, rehabilitative for common conditions
- Community participation is key
- Population served: 1 PHC per 30,000 population (rural); 1 Sub-centre per 5,000 population
(b) Secondary Health Care (Second Level / First Referral Level)
- Deals with more complex problems that cannot be managed at primary level
- Essentially curative services
- Serves as the First Referral Level in the health system
- In India: District Hospitals and Community Health Centres (CHCs)
- Services: Specialist consultations, surgeries, investigations, inpatient care
- Population served: 1 CHC per 1,00,000 population; 1 District Hospital per district
(c) Tertiary Health Care (Third Level)
- Offers super-specialist care
- Provided by regional/central level institutions
- Provides: Highly specialized care, planning and managerial skills, teaching for specialized staff
- Supports and complements actions at primary level
- In India: Medical college hospitals, AIIMS, PGI, regional specialized hospitals
Summary Table
| Level | Facility (India) | Services |
|---|
| Primary | Sub-centre, PHC | Basic/essential care, preventive, MCH |
| Secondary | CHC, District Hospital | Specialist, first referral, inpatient |
| Tertiary | Medical College, AIIMS | Super-specialist, teaching, research |
Importance of Referral System
- Ensures appropriate care at each level
- Prevents overburdening of higher-level facilities
- Promotes continuity of care
- Makes health services cost-effective and efficient
SHORT ESSAY 6: Elements of Evaluation of Health Services
Definition of Evaluation
Evaluation is "the process of determining the value or degree of success in achieving a predetermined objective. It includes recommending needed change." (WHO)
Steps of Evaluation (General)
- Determine what is to be evaluated
- Establish standards and criteria
- Plan the methodology
- Gather information
- Analyze the results
- Take action
- Re-evaluate
Types of Evaluation
(a) Evaluation of Structure: Whether facilities, equipment, manpower, and organization meet accepted standards
(b) Evaluation of Process: How activities of the programme are carried out - compared with predetermined standards. "Medical Audit" (or "Nursing Audit") evaluates physician/nurse performance
(c) Evaluation of Outcome: End results - whether persons experience measurable health benefits. Traditional outcomes = "5 Ds" - Disease, Discomfort, Dissatisfaction, Disability, Death
Elements (Components) of Evaluation
(a) Relevance - Is the service needed at all? Appropriateness to the problem. (e.g., smallpox vaccination is now irrelevant)
(b) Adequacy - Has sufficient attention been paid to a course of action? Is the quantum of work/targets adequate?
(c) Accessibility - What proportion of the population can use the service? Barriers may be:
- Physical (distance, travel, time)
- Economic (travel cost, fees charged)
- Social and cultural (caste, language barriers)
(d) Acceptability - The service may be accessible but not acceptable to all (e.g., male sterilization, rectal cancer screening)
(e) Effectiveness - The extent to which the underlying problem is prevented or alleviated. Measures degree of attainment of objectives. Ultimate measures = reduction in morbidity and mortality rates
(f) Efficiency - How well resources (money, men, material, time) are utilized to achieve effectiveness. Examples: immunizations per year vs. accepted norm; percentage bed occupancy; cost per hospital day
(g) Impact - The overall effect of the programme on the health of the community and the socioeconomic development of the society
Key Indicators of Evaluation
- Structure indicators: staff strength, equipment availability
- Process indicators: ANC coverage %, vaccination rates
- Outcome indicators: MMR, IMR, disease prevalence
SHORT ESSAY 7: Health Problems of the Aged
