title: [Pharmacy Department standard procedures for clinical trial development].
abstract: BACKGROUND
  Regulations on good clinical practice in the execution of clinical trials require the establishment and compliance of normalised working procedures by the hospital Pharmacy Department. These procedures must indicate precisely each one of the processes involved in their development, e.g. the reception, custody, storage, preparation and dispensing of research samples.
  
  
  OBJECTIVE
  The aim of the present study is to analyse the information included in clinical trial protocols involved in the circulation of drug samples during the research stage and, based on the results obtained, to develop normalised working procedures for our hospital Pharmacy Department in order to carry out these clinical trials.
  
  
  METHODS
  Eleven items were defined in order to describe key processes involved in identification, storage, receipt, preparation, dispensation, administration, maintenance and return of research samples, as well as those related to the beginning and end or closing of a clinical trial. Information included in 39 clinical trial protocols that had been sent to the Hospital Ethics Committee for evaluation between January and August of 2002 and was analysed in terms of the items previously defined.
  
  
  RESULTS
  46% of the protocols included data from the monitor or person representing the sponsor. 64% adequately described conservation and storage conditions of the research samples; but in 39% of the studied cases external labelling descriptions did not comply with legislation. Only 15% of the cases included clear instructions on research sample reception and its acknowledgement. 25.6% reported correct handling and/or preparation instructions for research samples with parenteral administration. Sample dispensation procedures were correctly described in no more than 5.1% of the protocols analyzed. 41% included information for patients, relatives or nurses on administration and handling of research samples, but none of them included specific information pamphlets or three-page leaflets. Procedures for either returning research samples to the sponsor or for their maintenance and replacement were not specified in the 71.8 and 100% of the cases, respectively. Likewise, trial ending or closing dates as well as procedures that must be followed by the Hospital Pharmacy Department during these processes were not stated in 89.7% of the protocols. Finally, only 30.8% of the cases explicitly cite the hospital Pharmacy Department.
  
  
  CONCLUSIONS
  These results support and justify the need to improve clinical trial protocols in order for them to be performed in a secure, effective and efficient way. Besides, they have been the starting point to devise the normalised working procedures of the hospital Pharmacy Department for the development of the clinical trials.
