  36. Beware of the internet! • Some websites may contain information which is poorly evaluated, inaccurate and/or biased • Always consider: • Who are the authors? • Are key statements referenced? • Are the references reputable? • Is the information current? • Who owns or sponsors the site? • Is the site referred to by another authoritative site? • Always try and check an answer in another resource

  37. The internet may be good for... • Branded or foreign products • Identification of drugs and herbal products • Hospital guidelines or formulary evaluations • News regarding ‘unusual’ treatments • Street drugs and substance misuse

  38. The internet is not good for... • Drug interactions • ADRs • Formulation and compatibility queries • Pharmacoeconomics

  39. Tablet identification We all love role-play! Volunteers please?

  40. Communication skills

  41. Communication skills • The tablet identification role-play shows the importance of clear, concise, accurate communication • When handling an MI enquiry, do not make any assumptions and, if in any doubt, ask for further clarification on any aspect of the query • When dealing with an MI enquiry, it is important to control the conversation in order to extract all relevant background information to view the query in context

  42. Communication skills • Use a conversational tone (not a checklist!) • If necessary, consider explaining why you require the additional details you are requesting • Before ending the call, summarise the query to the enquirer (to ensure you & they agree what is being asked) • Agree a timescale for the answer (not “ASAP”)

  43. Communication skills • Consider the format in which the answer is to be given • Verbal (face to face or telephone) • Written (email v.s. letter) • If giving an answer by telephone, the quality of your enquiry answering service is likely to be judged on the 2-3 minutes when giving the answer • Spending a few minutes summarising the main points of your answer e.g. using bullet points, ensures all relevant information is provided and helps to keep the conversation ‘on track’ • Recapping (you to the enquirer, or vice versa) may be helpful to ensure the message is delivered accurately

  44. Communication skills • Verbal v.s. written answer? • Complexity of advice given? • How is the information going to be used? • Sometimes a verbal answer will require written confirmation • Email v.s. letter? • Style (formal v.s. less formal v.s. informal?) • Consider how the information is going to be used! • References? • Be aware of patient confidentiality issues • Patient identifiers & email addresses

  45. Communication skills • When writing (or speaking), consider using phrases such as: • “As you will know,...” • “As you will be aware,...” • Avoid using phrases such as: • “There are no reports of ...” • Instead, use phrases like: • “Following a detailed literature search, I have been unable to locate any reports of...”

  46. Over to you!

  47. Ethical dilemmas

  48. Ethical dilemmas – general points • You do not have to answer every question that you are asked. • Always give yourself thinking time before replying. • Consult with appropriate colleagues and/or managers before answering. • There is no one “right” answer to most ethical dilemmas, but you should be able to justify what you do.

  49. Ethical dilemmas – general points • Do not answer queries that are beyond your sphere of expertise or available resources. • Research your answers thoroughly, and document carefully everything that you do. • Patients - Risk, product licences and healthcare politics, consequences, the Public Domain, fairness, appropriate, patient confidentiality
