A total of 172 responses to questionnaires was returned, 34 of which are not included in the analysis for the following reasons. First, 18 respondents had never seen or read the Guidelines. For those who provided an address a copy of the Guidelines was sent with a further questionnaire requesting that it be filled in and returned; some complied with this request. Four pharmaceutical companies returned forms that were not filled in either because "The Company doesn't give donations" or because there was "No point in filling in the questionnaire as the company has its own donation policy". E-mail correspondence from a pharmaceutical company representative started with "We do not use your Guidelines" and continued with "We have our own guidelines". When asked gently if it was possible to see a copy, the representative replied "This guideline is an internal document, and therefore not subject to external distribution". Lastly, 14 largely identical replies from field offices of one organization were consolidated into one donor and one recipient reply. Data from the remaining 138 questionnaires were entered in the database and analysed.
