We found a continuing trend towards conducting DCEs across a broader range of countries .
However , the trend towards including fewer attributes was reversed , whilst the trend towards interview-based DCEs reversed because of increased computer administration .
The trend towards using more flexible econometric models , including mixed logit and latent class , has also continued .
Reporting of monetary values has fallen compared with earlier periods , but the proportion of studies estimating trade-offs between health outcomes and experience factors , or valuing outcomes in terms of utility scores , has increased , although use of odds ratios and probabilities has declined .
The reassuring trend towards the use of more flexible and appropriate DCE design s and econometric methods has been reinforced by the increased use of qualitative methods to inform DCE processes and results .
However , qualitative research methods are being used less often to inform attribute selection , which may make DCEs more susceptible to omitted variable bias if the decision framework is not known prior to the research project .
Background Discrete choice experiments ( DCEs ) are increasingly used in health economics to address a wide range of health policy-related concerns .
Objective Broadly adopting the methodology of an earlier systematic review of health-related DCEs , which covered the period 2001–2008 , we report whether earlier trends continued during 2009–2012 .
Patients', physicians', and pharmacists' preferences towards coagulation factor concentrates to treat haemophilia with inhibitors: results from the COHIBA Study.
Despite modern highly efficacious technologies , there is still a lack of consensus on how to optimally treat haemophilia patients with inhibitors . The aim of the study was to evaluate preferences towards the characteristics of different coagulation factor concentrates for haemophilia inhibitors patients , from the perspective of patients or their caregivers , haematologists and pharmacists . A discrete choice study was conducted . Potential products were described with eight selected characteristics : perceived viral safety , risk of anamnestic response , possibility of undergoing major surgery , frequency of infusions in prophylaxis , number of infusions to stop bleeding , time to stop bleeding , time to pain recovery and cost . Participants received 16 pairs of potential products and chose from each pair the option they considered better . Data were analysed with a r and om-effects conditional logistic model . Totally 1614 observations were obtained from 37 patients /caregivers , 39 physicians and 25 pharmacists from Italy . Cost was the most important characteristic to every group . For patients /caregivers , the next most important factors were : risk of anamnestic response , possibility of undergoing major surgery and perceived viral safety . For physicians , the next most important characteristics were : risk of anamnestic response , number of infusions to stop bleeding and possibility of undergoing major surgery . For pharmacists , the next most important factors were : time to stop bleeding , time to pain recovery and possibility of undergoing major surgery . Decisions on treatments must take into account patients clinical needs ; however , preferences can also play an important role in the choice and success of treatments . The results of this study could , therefore , help decision-makers to optimize the overall benefits of treatments
