Conjoint analyses | |||||||
Fraenkel [18] | USA | 2006 | ACA | 212 | NR | 4 | Patients’ treatment preferences were strongly influenced by route of administration. Patients’ preferred treatment option, across all simulations, was bisphosphonates |
de Bekker-Grob [17] | Netherlands | 2008 | DCE | 120 | Public | 5 | All attributes (effectiveness, side effects (nausea), total treatment duration, route of drug administration, and out-of-pocket costs) were important Patients preferred a tablet once a month than tablet once a week or injection once a month or every 4 months |
Darba [16] | Spain | 2011 | DCE | 166 | NR | 3 | All attributes (route of administration, place of administration and costs) were important Patients preferred subcutaneous injection one per day rather than intravenous injection once per year |
Hiligsmann [19••] | Belgium | 2014 | DCE | 257 | Amgen | 5 | All attributes (effectiveness, side effects, mode and frequency of administration and costs) were important Patients preferred either an oral monthly tablet or 6-month subcutaneous injection above weekly oral tablets, 3-month subcutaneous, 3-month intravenous or yearly intravenous injections Patients disliked being at risk of gastrointestinal disorders more than being at risk of skin reactions and flu-like symptoms |
Structured interviews | |||||||
Gold [23] | USA | 2006 | 617 women currently using bisphosphonates | Interviews | Alliance for Better Bone Health | Two medications: weekly vs. monthly bisphosphonate therapy | More patients preferred weekly therapy over monthly therapy (82 vs. 18 %), after receiving information about fracture efficacy differences |
Keen [22] | UK, Germany, France, Spain and Italy | 2006 | 1253 currently taking a weekly bisphosphonate or had no current or prior history of bisphosphonate therapy | Interviews | NR | Two medications: weekly vs. monthly bisphosphonate therapy | 82 % preferred weekly bisphosphonate and 18 % monthly therapy Efficacy was the most commonly cited reason for this preference Overall, 69 % of patients intended to ‘definitely/probably’ use the weekly therapy compared with 34 % of women who rated the monthly therapy similarly |
