Download - Drug information final
Introduction ; It is the current, relevant, critically examined data
about drug and drug use for given patient or situation.
Many institutes run DIC(Drug Information Center) for the provision of drug information, to every group/kind of people from any place
First DIC was developed in University of Kentucky in 1960. In United states 80% of the Hospitals having DIC.
Nepal, in infancy stage with a few centers.
In Nepal DDA has started this type of services.
Need of drug information The no of drugs in the international market has increased very much
The newer drugs are generally more potent & selective, and formulations becoming increasingly complex
The literature on drugs has also expanded and covers a wide range of information
To introduce a new drug into the practice, the professionals need to evaluate the given information.
A simple,quick reference to a pharmacopoeia or formulary is no longer sufficient.
Aims and objectives of drug information services The provision of information to health professionals on
specific problems related to the use of drugs in particular patients;
The provision of information to officials in government agencies to optimize the decision making process;
The preparation and development of guidelines and formularies;
To improve patient compliance and to provide a guide to responsible self medication;
To develop and participate in continuing education programs;
To participate in undergraduate and graduate teaching programs;
To develop educational activities regarding the appropriate use of drugs for patients in the community;
To prepare and distribute material on drugs to health personnel in the form of a drug Information bulletin and/or other media;
To develop and participate in research programs;
The Sources of information/Resources available
Primary Source: Information is presented by authors without any evaluation by a second party. Provides must current information about drugs. Examples; articles published in journals(eg British Medical Journal), thesis etc.
Secondary source The original source has been evaluated by second party other than the publisher. Modified and rearranged form Examples; review articles like lexis-nexis, Medline etc
Tertiary source Information obtained from primary and secondary source and arranged in a
manner to represent a composite of the available information. Examples; Representative form Pharmacopeias - BP, USP, IP, BNF etc.,
Encyclopedia Dictionaries Guides, text books
Other Sources:
The DIC also receives information from The public and hospitals about the Adverse effects of any drug Local drug lists National Formularies Hospital Formularies Internet Phone calls to Manufacturers Government and Non-government organizations and also to other DIC’s.
Drug informer should understand the nature of the question and should ask all the needed questions to get the ultimate question
Most specialists today use the modified systematic approach designed by ‘Host and Kirkwood’, these are;
Step I ; Secure demographics of the requestorsStep I ; Secure demographics of the requestors Who requests? Med/non med personnel Educated/un educated personnel Name/location/phone/email etc of requestor This determines the type of response that will be given
Step II; Obtain background informationStep II; Obtain background information Where the requestor heard/read about the drug? Is he/she taking medicine? Why? Is he/she a caregiver/wants to take medicine? This helps determining what additional information should be
provided.
Step III; Determine and categorize the ultimate questionStep III; Determine and categorize the ultimate question Putting the pieces of information together to form ultimate
question and once it has been determined, the next step is to categorize the question.
Step IV;Develop strategy and conduct researchStep IV;Develop strategy and conduct research Strategies should be developed with a typical algorithm with three
essential components; tertiary-secondary-primary literature
Step V;Perform evaluation, analysis & synthesisStep V;Perform evaluation, analysis & synthesis Provider should take time to evaluate the info, analyze and then
synthesize it into a good reply
Step VI;Formulate and provide responseStep VI;Formulate and provide response An outline should be established to help formulate a
response to the drug info request.
Its important to have; introduction, body and conclusion
Step VII;Conduct follow-up and documentationStep VII;Conduct follow-up and documentation Checking with the requestor to make sure his/her
question has been sufficiently and completely answered.
Of vital importance is to document all the steps taken in this process.
Among the skills of drug information is a knowledge of drug literature evaluation which allows one to provide a critical analysis of the literature and have a better understanding of the studies done in health and medicine.
It is a key component to provide a good quality answer to a requester
Being able to separate good data from poor data is essential
Knowing the limitations of any study can help in evaluating the usability of its data
Drug information specialists will often use some standard questions to help in this process
Several references provide guides to evaluate the medical and pharmacy literature.
Do not guess
Take several ethical issues into account◦ Patient privacy must be maintained
◦ Patient-physician relation cannot be breached
◦ Response is not necessary if the inquirer intends to misuse or abuse the information that is provided.
Organize information before attempting to communicate the response to the inquirer.
Tailor the response to the inquirer’s background.
Tell the inquirer where the information was found.
Alert the inquirer of a possible delay when it takes longer than anticipated to answer the question.
Ask if the inquirer’s question is answered by the information.
Research the Facts, gather information(from the resources available i.e. tertiary- secondary- primary resources)about the question of oral report.
List the facts and interesting information accurately. Remember that relevant details and vivid descriptions will make
oral report more interesting
Organize the Information/oral report in three parts. ◦ Introduction ◦ Body (main part)◦ Conclusion
Practice Giving the Oral Report Speak clearly and deliberately Make A Final Copy of Report Notes.
Drug information centersDrug information centers Drug information centers (DICs) in general, are service
providers, which provide drug information relating to therapies, pharmacoeconomics, education, and research programs.
It provides unbiased information to health care professionals and/or patients and consumers.
Many centers also provide workshops or other forms of training to enhance the skills of healthcare professionals.
A drug information center is usually a unit located within and/or affiliated with a larger organization (i.e., a pharmaceutical association, a hospital etc).
Pharmacist; specialists with proper knowledge of drug and actions associated with it with academic degree. ƒ
(they provide drug information)
Pharmacy Technicians & Students(they assist pharmacists in providing drug information like
literature searching,retrieval of data,resources updating etc)
People trained in library science with computer knowledge
(they are supporting staffs in DIC for their own expertise)
ƒ
The center should have specific hours of operation(24hrs preferably) and adequate technological resources (i.e., computers, phone lines, faxes, etc.)
The drug information center should have the latest publications and ideally publish a newsletter or other informational updates.
Role of Pharmacist: Must be a part of DIC,should be “ready to go” for
information all the time. ‘The Drug-Information Pharmacist’ is at interface of vast
amount knowledge on onside and the persons needing the knowledge on other.
Should provide proper information irrespective of the informer’s status,but accordingly with informer’s status.
Drug Information Centers in Nepal Four organizations in Kathmandu were initially identified as potential
sites for drug information centers:
Department of Drug Administration (DDA), Ministry of Health Drug Information Unit(DIU), Tribhuvan University Teaching
Hospital Resource Centre for Primary Health Care (RECPHEC), a local non-
governmental organization Nepal Chemists and Druggists Association (NCDA), a professional
association for retailers and wholesalers A fifth organization, the Nepal Health Research Council(NHRC),
also expressed an interest in establishing a drug information center. NHRC is a relatively new, quasi-governmental body whose mission is to review and approve all proposals for medical and health research to be conducted in Nepal.
Drug Information Network of Nepal (DINoN)Drug Information Network of Nepal (DINoN) The Drug Information Network of Nepal (DINoN) was established on
23rd September, 1996 with multi-sectoral participation including government, academic and non-government institutions to provide unbiased information on drugs to various constituency groups.
A single organization may not have enough expertise, resources and capacity to satisfactorily meet the drug information needs of a wide range of target groups
DINoN is an initiative to develop and disseminate information about the proper use of drugs, possible adverse reactions, contraindications, toxicity, drug standards and efficacy, precautions, and proper storage and handling to health care professionals in the public and private sector, and to consumers.

Note; The primary role of a DIC in a developing country is to give clear anddefinitive information on well-established essential drugs andpromote their rational use.
A secondary role would be to keep up-to-date with pharmacological and therapeutic literature and to disseminate relevant
information, as it becomes available.
Drug information bulletin It publishes the latest developments in medical sciences, the newly introduced
drugs, new indication and other information regarding drugs.
One of the PTCs duties is to assist the pharmacist in conducting a teaching program within the hospital through a pharmacy publication.
The methods employed to disseminate interdepartmental information are usually bulletins, bulletin board notices and committee meetings.
The bulletin normally publishes the latest development in the medical sciences, the newly introduced drugs, new indications for certain drugs, newer drug delivery systems, updates on drug interactions and ADRs.
Pharmacist is normally held responsible for its publication however; contributions are obtained from pharmacists, physicians and nursing and other interested groups like therapeutic dietician for food drug interactions for publishing the bulletin.
The contents should however be educative and informative.
