Lead me not into temptation: drug price regulation and dispensing physicians in Switzerland

While most countries separate drug prescription and dispensation to ensure independent drug choice, some allow this combination to increase pharmaceutical access in rural areas or to increase the utilization of pharmacist skills. A drawback of this approach is that dispensing physicians or prescribing pharmacists may be incentivized to increase their own profits through the prescription of cost-inefficient drug packages, leading to an increase in pharmaceutical spending. Switzerland constitutes an interesting example of where dispensing and non-dispensing physicians coexist, permitting a comparison of their prescribing behavior. The present study shows that drug margin optimization is possible under the current drug price regulation scheme in Switzerland. Using drug claims data, empirical findings indicate a 5-10% higher margin per dose for dispensing physicians compared to pharmacists. Cost per dose is 3-5% higher when dispensed by physicians instead of pharmacists
