Need for Surveillance The Government of India realized the importance of Disease surveillance after the Cholera outbreak in Delhi and the Plague outbreak in Surat, which not only had significant mortality and morbidity but also significant economic consequences.

National Surveillance Programme for Communicable Diseases (NSPCD) NSPCD was therefore launched by the Centre

National Surveillance Programme for Communicable Diseases (NSPCD) NSPCD was therefore launched by the Centre in 1997 -98 in five pilot districts of the country (centrally sponsored scheme) and over the years extended to cover 101 Districts in the country in all 35 states and UTs in the country.

NSPCD n n In this programme the states are the implementing agencies and NICD

NSPCD n n In this programme the states are the implementing agencies and NICD Delhi is the Nodal agency for coordinating the activities. This programme is based on outbreak reporting (as and when outbreaks occur) with weekly reporting of epidemic prone diseases directly from Districts (including nil reporting) to the Centre.

Main strategy To establish Early Warning System (EWS) so as to institute appropriate and timely response for prevention & control of outbreaks n Every state/UT and all the 101 districts has a trained multi-disciplinary Rapid Response Team n Rapid communications (through e-mails & fax) n Strengthening of state and district laboratories for rapid confirmation of diagnosis n Capacity development of health staff in the districts n IEC (information, education and communication)

NSPCD n n NSPCD has significantly improved the capacity of these districts and states to detect investigate and respond to outbreaks, yet It was not case based reporting and did not give a complete picture of disease burden in the country especially in respect of epidemic prone diseases Go.

National Issues n n n Political considerations based on Centre-state relations Central assistance proportionate to political affiliations Media attention an important consideration for response Time constraints-inadequate time given for outbreak investigation Hesitancy for international assistance either in Outbreak Investigation or Lab support

National Issues cont’d n n Reduced attendance in public health system and increased in

National Issues cont’d n n Reduced attendance in public health system and increased in private sector almost 40: 60 or more Wide-spread quackery in the name of alternate medicine (ayurveda, unani, homeopathy, etc) ‘Overworked’ clinicians so poor maintenance of medical records like case sheets/prescription slips/provisional diagnosis/etc Lack of ownership by states of central vertical programmes

State issues n n n n State RRT not utilized to full potential Regional

State issues n n n n State RRT not utilized to full potential Regional labs strengthened but lab diagnosis not enhanced & increasing dependence on Centre Insufficient epidemiological analysis No clear IEC strategy Frequent transfer/retirements of trained staff so programme invariably suffers Shortage of staff so multi-tasking for state and district level functionaries. Fund issues and Utilization certificates

State issues cont’d n n Lack of competent staff especially Public Health Professionals and

State issues cont’d n n Lack of competent staff especially Public Health Professionals and Microbiologists in majority of the states. Short trainings not likely to build the necessary capacity. Clear demarcation between the Directorate of Health Services and Directorate of Medical Education so difficulties in integrating Medical colleges

District issues n n n Programme is focused on district epidemic preparedness and response

District issues n n n Programme is focused on district epidemic preparedness and response but some districts yet to get their act together Reporting from periphery needs improvement. If media first reporting then SURVEILLANCE FAILURE Weekly reports incomplete and irregular (and under reporting) Monthly reports also irregular (CBHI has to increase its role & responsibility) Communication ‘failure’ CMO-CMS-DSO lack of co-ordination

District issues cont’d n n Overworked peripheral staff to whom all programmes are dependent

District issues cont’d n n Overworked peripheral staff to whom all programmes are dependent on Multiple formats for different programmes Rapid Response Teams usually composed of specialists from District hospital/ Medical college and problem in rapid mobilization as from different agencies Concept of Nil reporting/routine reporting difficult for the peripheral staff to understand, compounded by lack of feedback from the higher levels

District lab issues n n District labs few established and functioning satisfactorily Many labs

District lab issues n n District labs few established and functioning satisfactorily Many labs in a district: • Public health lab-testing water samples • Hospital lab-testing for NCDs and clinical requirements • Medical College lab-testing for majority of the diseases • Surveillance lab-testing for few diseases • District blood bank –with ELISA reader • Peripheral labs-Microscopy only Co-ordination between these labs so that overall district lab capacity enhanced
