The Pharmacovigilance Programme of India (PvPI) aims at sensitizing the healthcare professionals towards strengthening the Spontaneous reporting system in order to protect the lives of millions of people living in a vast country like India. Currently India’s contribution to global drug safety database is about 3%, which is meagre in comparison with the huge population. In terms of number India has reported 1,81,656 ADR’s over the period from April 2011 – March 2016 to National Coordination Center (NCC) for Pharmacovigilance Programme of India (PvPI).This present study was done to identify the possible factors responsible for underreporting (UR) of adverse drug reactions (ADRs) and encourage the healthcare professionals to substantiate the Pharmacovigilance Programme of India (PvPI). The present study was a cross-sectional questionnaire-based study to assess the knowledge, attitude, and practice (KAP) of pharmacovigilance among practicing healthcare professionals working in the Saveetha Medical College & Hospital, Thandalam, Chennai. The statistical analysis was done using Statistical Package for Social Sciences (SPSS) version 23 software. The result shows difference in explicit knowledge and tacit knowledge among healthcare professionals. Attitude questions have identified the affective behaviour of the respondents and practice questions shows evidence of a paradigm shift towards an organized pharmacovigilance constructivism. KAP of the healthcare professionals highlights the under-reporting of ADR, Multimodality interventions are needed to improve spontaneous ADR reporting.

Pharmacovigilance is the pharmacological science relating to the collection, detection, assessment, monitoring and prevention of adverse effects or any other drug-related problem, mainly long term or short term side effects of pharmaceutical products1. Pharmacovigilance Programme of India (PvPI) was formed in July 2010. A combined initiated by Central Drugs Standard Control Organization (CDSCO), New Delhi, MoHFW, Government of India. The All India Institute of Medical Sciences (AIIMS) was established as the National Coordinating Centre (NCC) under which 22 ADR monitoring centers (AMCs) all over India were formed for monitoring Adverse Drug Reactions (ADR) in India. In order to strengthen the programme , and for better implementation , the National Coordinating Centre was relocated to Indian Pharmacopoeia Commission (IPC), Ghaziabad, (U.P.) from the All India Institute of Medical Sciences (AIIMS)2.
The committees under the National Coordinating Centre (NCC-PvPI) are the Steering committee, working group, Quality review panel, Signal review panel and the Core training panel (Fig.1). At present, there are 202 ADR monitoring centers under Pharmacovigilance Programme of India (PvPI). The eventuality of ADR’s contributes significant burden to the country’s economy and also loss of quality of life. The foremost responsibility of the Health care professionals is to report the ADR’s arising out of the drugs promptly and efficiently. In our country, there is a huge divergence in the population with regard to genetic and cultural traditions. So these in formations shape the future of the government policies to protect the well-being of the people 3.
The Uppsala Monitoring Centre (UMC) in Sweden has the international database of suspected adverse drug reaction reports from all over the world4. Studies conducted among hospitalized patient populations have revealed staggering facts of incidence of serious ADR’s. These studies judged that 6.7% of hospitalized patients of the total admissions incidence of serious adverse drug reaction with a fatality rate of 0.32% 5. The present issue of concern is underreporting of ADR’s due to various confounding factors6. The knowledge, attitude, and practice (KAP) is the best tool to assess ADR reporting among healthcare professionals and their perspective towards Pharmacovigilance and patient’s safety7, 8, 9. Hence there is a need for spontaneous reporting habit among healthcare professionals as a long term goal in order to strengthen the PvPI8.

Materials and Methods
This study was conducted at Saveetha Medical College Hospital, Thandalam, a multispecialty tertiary care hospital in Chennai. The approval for conducting this study was obtained from the Institutional Ethics Committee [012/01/2016/IEC/SU] prior to the study. The study was conducted during the period from April 2016 to September 2016.
This was a cross-sectional questionnaire-based study. The study participants consisted of all the practicing healthcare professionals (doctors, nurses and pharmacists) who gave their informed consent and who were working at the hospital during the study period7, 8, 9.KAP questionnaire was designed to assess the demographic details of the healthcare professionals, their knowledge of pharmacovigilance, attitudes towards pharmacovigilance, and their practice on ADR reporting7, 8, 9. There were 20 questions in the questionnaire to assess the knowledge on ADR, attitude towards pharmacovigilance and their practice on reporting ADR. The study instrument was a self-administered KAP questionnaire designed by the faculty of the Department of Pharmacology based on previous studies.
Study Data Collection
A total of 230 healthcare professionals participated in this cross sectional questionnaire based study. A time period of one day was given for the participants to read, understand and answer the questions.
Information from the returned questionnaire were entered and analyzed by Statistical Package for Social Sciences (SPSS) version 23 software.
Results and Discussion
Of the 300 KAP questionnaires circulated, a total of 230 healthcare professionals (Doctors 147, Nurses 83) gave consent to participate in this study and responded to the questionnaire. The demographic details of the healthcare professionals with baseline characteristics are summarized in (Table 1)

Healthcare Professionals Knowledge Regarding ADR Reporting
Healthcare professionals knowledge was gauged based on important parameters, 53.4 % of the respondents gave correct response regarding the definition of Pharmacovigilance. 51.7 % of the respondents were aware of the importance of pharmacovigilance. 61.7 % of the healthcare professionals had knowledge about Post Marketing Surveillance (PMS). 59.5 % of the respondents were aware of the regulatory body responsible for monitoring ADR’s in India (Table 2). The results of the present study are slightly lower with regard to knowledge when compared to a similar study done by Gupta et al9 and Dharmadhikari PP et al10. Response rate was around 72.1 % regarding banned drugs due to ADR. The awareness about Pharmacovigilance Programme of India (PvPI) was around 83.1 % among healthcare professionals which leads to constructivism towards pharmacovigilance (Table 3), this value is slightly higher than the similar study done by Gupta et al9.

This study concludes that the health care professionals knowledge towards ADR reporting is better and their commendable attitude towards a uniform structured system of ADR reporting. It identified the factors discouraging ADR reporting and emphasized on spontaneous ADR reporting. The under-reporting issues can be corrected by conducting periodic educational interventional15 programs and sensitizing programs for the health care professionals working in a tertiary care hospital13,14.The health care professionals practice towards ADR reporting showed positive trend towards improving ADR reporting and safeguarding the safety of the patients16.
We would like to express our gratitude to all the health care professionals who participated in this study.
