Pharmacovigilance is the subject that deals with the detection, assessment, understanding, and prevention of adverse effects of drugs, or any other drug-related problems. Ecopharmacovigilance is the science & activity concerning detection, assessment, understanding and prevention of adverse effects or other problems related to the presence of pharmaceuticals in the environment, which affect human & other animal Ministry of Health and Family Welfare, Govt. of India has set up National Pharmacovigilance Programme (NPP) with the aim use of medicine and outweighs the risks and thus protecting the health of the people of the country. It was observed in our institution Pharmacovigilance Programme that the problems of underreporting and lack of awareness were prevalent in the community of health professionals. This study shows poor knowledge, attitude and practices of pharmacovigilance among medical professionals so that there is urgent need to improve the awareness of Pharmacovigilance among the healthcare professionals in the institute. Our ADR reporting should be intensively taught during undergraduate study, and this should be start of internships as well as periodically thereafter through con education programs.

In the year 2004, to ensure the benefits of reinforced at the tinuous PAPER-QR CODE Research Article ISSN: 2277-8713 Sanjeev Sharma, IJPRBS, 2013; Volume 2(3): 234-247 IJPRBS Available Online At www.ijprbs.com Introduction: The safety of patients and the safe use of medicines are high priorities in the modern world. The first practical international cooperation in drug monitoring started in 1968. The ideas came up as a consequence of the so-called thalidomide tragedy. In the 1960s it was discovered limb deformities in babies may occur if thalidomide is ingested by mothers during pregnancy. This incident became the modern starting point of a science focusing on patient problems caused by the use of medicines. Pharmacovigilance, according to WHO is defined as the science and activities relating to the detection, assessment, understanding, and prevention of adverse effects of drugs, or any other drug-related problems 1 . Newly emerging Ecopharmacovigilance is the subject that deals with the sources of entry of pharmacoceuticals into environment, consequences of environmental pollution by pharmaceuticals and its remedial measures 2 . It starts from the clinical stage and continues throughout the product life cycle of the drug, mainly divided as premarketing pharmacovigilance (that is clinical trial phase) and post-marketing pharmacovigilance. Pharmacovigilance is particularly concerned with adverse drug reactions (ADRs) which are defined as an unintentional noxious response by a drug that occurs at doses normally used for the prophylaxis, diagnosis, treatment of diseases and for the modification of physiological function 3 . In the year 2004, Ministry of Health and Family Welfare, Govt of India set up National Pharmacovigilance Programme (NPP) with the aim to ensure that the benefits of use of medicine and outweighs the risks and thus safeguard the health of the people of the country. India is now regarded as one of the countries where a vast number of new drugs are being introduced every year and also a ‘big market for Generic Drugs, Clinical trials & Drug Discovery & Development’, which throw up the challenges of monitoring ADRs over large population base in the country. All medicines (pharmaceuticals and vaccines) as a rule have known or unknown side effects. However many adverse drug reactions (ADRs) are preventable but it demands a good knowledge of Research Article ISSN: 2277-8713 Sanjeev Sharma, IJPRBS, 2013; Volume 2(3): 234-247 IJPRBS Available Online At www.ijprbs.com pharmacology and good prescribing practices. 3 It is important to monitor every undesirable effect of medicines to get any new information in relation to their ADR’s profile. In a country like India with big population load, with vast ethnic diversity, differences in disease prevalence patterns among different regions, various systems of medicines like Ayurveda, Homeopathy, Unani & Allopathy and different socioeconomic status, it become important to have a proper pharmacovigilance and drug safety monitoring programme for the country. Collection of ADR’s information and its analysis to reach a meaningful conclusion on the continued use of these medicines is the aim of Pharmacovigilance. The results thus obtained will be useful in changing the labeling of medicines indicating restriction in use or issue of statutory warning, precautions, or even withdrawal of the drug from the market. This also helps in educating doctors about ADRs, and in the official regulations of drug. In India the whole programme is controlled by the Central Drugs Standard Control Organization (CDSCO), Ministry of Health and Family Welfare, Govt. of India with the objectives of: 1. To monitor Adverse Drug Reactions (ADRs) 2. To increase awareness among health care professionals about the importance of reporting an ADR. 3. To have an eye on the benefit-risk profile on the use medicines in particular disease. 4. To create independent, evidence based recommendations regarding the safe use of medicines in the country. 5. To help the Drug control organization of the country to formulate safety related guidelines for the use of the medicines. 6. Exchange information with all key stakeholders. 7. Establishment of national center of excellence which works at par with global drug safety monitoring standards The core data in the pharmacovigilance programme is generated through the identification & spontaneous reporting of Research Article ISSN: 2277-8713 Sanjeev Sharma, IJPRBS, 2013; Volume 2(3): 234-247 IJPRBS Available Online At www.ijprbs.com any suspected ADR by the healthcare professionals or in some countries by the consumer himself to their national pharmacovigilance centers or to the drug manufacturing company. The ADR report is almost submitted voluntarily. It is highly unfortunate that the ADR reporting is underreported in many countries including the developed countries and rarely exceeds 10% for the serious ADRs though the data vary greatly between countries and in relation to minor & serious ADRs. Overall underreporting of ADRs is a common problem in pharmacovigilance programs 5,6 . The overlooking of ADRs by the healthcare professionals is a common problem encountered in the pharmacovigilance programme. The reason for the problem may vary from the heavy workload, pathetic attitude towards ADR reporting, lack of knowledge about ADR reporting or the fear that reporting may affect their career. After observing the Pharmacovigilance programme of our institution we found that the problems of underreporting and lack of awareness were prevalent in the community of health professionals. It was found that in the year 2012 only 30 ADRs were reported by the health professionals. This inspires us to conduct a study to know the awareness of Pharmacovigilance among health professionals of our institute. Aim of our study is to create awareness of pharmacovigilance among health professionals and to uncover the causes of underreporting. In this study we also aimed to know the suggestions to improve the ADRs reporting in our institute. Material and Methods: The present study is a randomized questionnaire-based survey, conducted at a 750-bedded tertiary care teaching hospital in Indore, India. This questionnaire survey was conducted during March 2013 and approval from Institutional Ethical Committee was obtained prior to administering the questionnaire survey. The questionnaire, contains 16 questions regarding knowledge, attitude and practices of Pharmacovigilance and Ecopharmacovigilance along with suggestions to improve ADR reporting, was designed based on similar previous studies. 7, 8 Factors that discouraged reporting and demographics of participants were also included in questionnaire. Study Research Article ISSN: 2277-8713 Sanjeev Sharma, IJPRBS, 2013; Volume 2(3): 234-247 IJPRBS Available Online At www.ijprbs.com was done on health professionals (doctors, nursing staff & pharmacists) working in the medical college & hospital. Pretesting of questionnaire was done on 5 randomized selected health professionals of the institute to identify any potential bias and mistakes. The name of the health professional was kept optional to avoid potential bias and to increase the number of responders but designation asked. The aim of study & questionnaire were discussed among the members of Pharmacovigilance committee and to the participants. For submission of questionnaire time of 1 day was given and for those who had lost the questionnaire, we didn’t resupplied the questionnaire. The information was recorded and analyzed using the Microsoft Excel worksheet (Microsoft Office 2010) and the ANOVA test. P value less than 0.05 was considered to be statistically significant. Result: The questionnaire was supplied to 200 health professionals and we got back 146 responses making a 73% of responses. The response rate was 56% among senior faculty members (Professor and Associate Professor), 84% among junior faculty members (assistant professor, senior resident and junior resident) and 92% were among paramedics (pharmacist and nursing staff). The demographic profile of responders is shown in table1. Awareness about pharmacovigilance based on our assumption of response to question number 1 of the questionnaire were calculated and it was found that 77% were aware and remaining 23 % were unaware. Awareness of pharmacovigilance among senior faculty members was 88.8%, junior faculty members 91.6%, while in paramedics were 59%. We did not include the responses of unaware respondents in further statistical analysis of questionnaire. We assess the knowledge of respondents on the basis of question number 2-6 and gave maximum 10 marks. The mean knowledge of senior faculty members was 7, junior faculty members Research Article ISSN: 2277-8713 Sanjeev Sharma, IJPRBS, 2013; Volume 2(3): 234-247 IJPRBS Available Online At www.ijprbs.com were 8.5 and paramedical staff was 6.69. Knowledge of junior faculty was significantly higher (p<0.05) as compared to senior faculty. When we talked about existence of pharmacovigilance committee in the institute only 62.5% senior faculty and 23.07% paramedical staff knew that such a committee existed, while among junior faculty 81.8% were aware of pharmacovigilance committee. 87.5% senior faculty members, 91% junior faculty members and 77% paramedical staff thought that ADR reporting is a professional obligation. Only 15% respondents receive training on how to report ADR to pharmacovigilance committee and 5% respondents had guided others on importance of ADR reporting but it is interesting that all respondents thinks that Pharmacovigilance should be taught in detail. Source of knowledge about ADRs of drugs of respondents are given in table II. Only 30% senior faculty and 25% paramedical staff had recorded ADRs while in case of junior faculty 45% had recorded ADRs. It was found that none of the respondent were aware about the Ecopharmacovigilance.
