title: Validating a hospital medicines formulary survey in the Western Pacific Region--a global hospital pharmacy initiative based on the Basel Statements.
abstract: BACKGROUND
  In 2008, the Basel Statements were developed to reflect the future of hospital pharmacy worldwide. Included were a key set of statements regarding the expanding role of hospital pharmacists' influence on prescribing from the management of medicines formularies to being an active member of the therapeutic decision-making process.
  
  
  OBJECTIVE
  This study aimed to validate a survey to measure Basel Statement 26 regarding the role of medicines formularies and the factors that affect its use in the Western Pacific Region (WPR).
  
  
  METHODS
  The survey was developed in consultation with a WPR advisory group and current literature. The survey was translated using the forward-backward method into Chinese (simplified) and Vietnamese. The instrument was pilot tested in a stratified random sample of 260 hospital pharmacy directors in the WPR. Principal components analysis (PCA) was applied to the data to assess construct validity of the Medicines Formulary Scale that assessed responders' perceptions of their formulary and impact on utilization.
  
  
  RESULTS
  The Medicines Formulary Survey was completed by 107 hospital pharmacy directors or equivalent. The survey contained the Medicines Formulary Scale in addition to questions regarding the content and review process of the hospital's formulary as well as demographic questions. Application of the PCA procedures resulted in a parsimonious 2-factor solution in which 33.8% of the variance was explained. The Cronbach alpha for the 17-item scale was found to be 0.70. The Cronbach alpha values for the first and second factor/subscales were 0.76 and 0.68, respectively.
  
  
  CONCLUSIONS
  The Medicines Formulary Survey appears reliable and valid for assessing hospital pharmacy directors' perceptions of hospital medicine formularies in the WPR. Further development of validated instruments to assess other areas of hospital pharmacy practice will help track the progression of hospital pharmacy and aid in globalization of the profession.
