  1. 1. IDSP – Integrated Disease Surveillance Programme Dr. Dharmendra Gahwai ( MD- Community Medicine, DAE ) DD/State Epidemiologist (IDSP) Directorate of Health Services Raipur (C.G.)
  2. 2. Surveillance
  3. 3. Surveillance • Surveillance is a French word meaning - “ Watch with attention, suspicion and authority” • Surveillance is defined as – “ongoing systematic collection, collation, analysis and interpretation of data and dissemination of information to those who need to know in order that action be taken.”
  4. 4. Surveillance is – “Information for Action”
  5. 5. Why do we need to do surveillance? • To determine incidence of disease • To know the geographical distribution or spread of disease • To identify population at risk of that disease • To monitor trend of disease over a long time period • To capture the factors and condition responsible for occurrence and spread of disease • To predict the occurrence of epidemic and control of epidemic • To evaluate the effectiveness of an intervention or programme
  6. 6. What are the Key Elements of Surveillance System? • Detection and notification of health event • Investigation and confirmation (epidemiological, clinical, laboratory) • Collection of data • Analysis and interpretation of data • Feed back and dissemination of results
  7. 7. Health Care System................Public Health Authority
  8. 8. • The disease burden of the people of India is one of the highest in the world. • India have dual burden of Infectious Disease and NCD. • Planning for disease prevention and controls depends upon the disease frequency, distribution and determinants that can be made available through proper surveillance. • Surveillance has been identified as backbone of any health delivery system.
  9. 9. History • NSPCD(National Surveillance Programme for Communicable Diseases) Launched in • 1997 - 5 districts • 1998 - 20 more districts • 1999 - 20 more districts • 2003 - more 101 districts  Nov. 2004 - IDSP launched  (up to 2010) • 2010 - Extended for 2 more years  2012- Integrated Disease Surveillance Programme The IDSP proposes a comprehensive strategy for improving disease surveillance and response through an integrated approach.
  10. 10. Phases of implementation • Phase I (2004-05) – Madhya Pradesh, Andhra, Himachal, Karnataka, Kerala, Maharashtra, Mizoram, Tamil Nadu & Uttaranchal • Phase II (2005-06) – Chattisgarh, Goa, Gujarat, Haryana, Orissa, Rajasthan, West Bengal, Manipur, Meghalaya, Tripura, Chandigarh, Pondicherry, Nagaland, Delhi • Phase III (2006-07) – UP, Bihar, J&K, Punjab, Jharkhand, Arunachal, Assam, Sikkim, A&N Island, D&N Haveli, Daman & Diu, Lakshadweep
  11. 11. • IDSP was formally launched in Chhattisgarh on 19th of November 2005.
  12. 12. Mission • To strengthen the disease surveillance in the country by establishing a decentralized State based surveillance system for epidemic prone diseases to detect the early warning signals, so that timely and effective public health actions can be initiated in response to health challenges in the country at the Districts, State and National level.
  13. 13. Objectives • To establish a decentralized district based system of surveillance for communicable and non-communicable diseases, so that timely and effective public health actions can be initiated in response to health changes in the urban and rural areas. • To integrate existing surveillance activities to avoid duplication and facilitate sharing of information across all disease control programmes and other stake holders, so that valid data is available for health decision making in the district, state and national levels
  14. 14. Components • Integration and decentralization of surveillance activities through establishment of surveillance units at Centre, State and District level. • Human Resource Development – Training of State Surveillance Officers, District Surveillance Officers, Rapid Response Team and other Medical and Paramedical staff on principles of disease surveillance. • Information Communication Technology - for collection, collation, compilation, analysis and dissemination of data. • Strengthening of public health laboratories
  15. 15. What is integration? • Sharing of surveillance information of various disease control programmes. • Developing effective partnership with heath and non health sectors in surveillance. (Inter-sectoral Coordination). • Including communicable and non communicable diseases in the surveillance system. • Working with the private sector and non governmental organization . • Bringing academic institutions and medical colleges into disease surveillance.
  16. 16. Conditions under regular surveillance Type of disease Disease Vector borne diseases Malaria Water borne diseases Diarrhoea, Cholera, Typhoid Respiratory diseases Tuberculosis Vaccine preventable diseases Measles Disease under eradication Polio Other conditions Road traffic accidents International commitment Plague Unusual syndromes (Causing death/hospitalization) Meningo-encephalitis Respiratory distress Hemorrhagic fever Other undiagnosed condition

  18. 18. State-Specific Diseases Chhattisgarh 1. Leprosy 2. Viral Hepatitis 3. Neonatorum Tetanus 4. Diphtheria
  19. 19. State-specific diseases • Madhya Pradesh, Uttaranchal – Diphtheria, neonatal tetanus, leprosy • Maharashtra – Diphtheria, neonatal tetanus, leptospirosis • Andhra Pradesh – Filariasis • Karnataka – Filariasis, KFD & HGS, leptospirosis • Tamil Nadu – Leprosy, leptospirosis • Kerala – Leptospirosis • Mizoram – Cancer, substance abuse, acid peptic disease, pneumonia
  20. 20. Classification of surveillance in IDSP • Syndromic – Diagnosis made on the basis of clinical pattern by paramedical personnel and members of community . – By Health Workers, at Village/ SHC level on the basis of symptoms. • Presumptive – Diagnosis is made on typical history and clinical examination by medical officers. (Health Facilities- PHC/CHC/DH etc. ) • Confirmed/Laboratory – Clinical diagnosis confirmed by appropriate laboratory identification. – at CHC, District Hospital and Medical Colleges Labs for confirmation.
  21. 21. Types of Weekly Reports under IDSP 1. Syndromic Surveillance report in “S” form, collected by Health Workers, at Village level and submitted at CHC. 2. Presumptive Surveillance report in “P” form, generated by Medical Officers, collected by Pharmacist/ Health Workers, 3. Lab Surveillance report generated by Lab Technicians, at CHC and District Hospital Labs. 4. Compiled reports are entered online on IDSP portal by BADAs at block level. 5. Reports are analyzed at District & State level, Reported to higher level, feed back to lower levels. 6. Outbreak & Early Warning Signals report at District and State level.
