As of now, 29 provinces (autonomous regions, municipalities directly under the central government) and Xinjiang Production and Construction Corps have launched a designated pharmacy price comparison mini program, which can realize one click query, real-time comparison, and location navigation of drug prices on mobile phones. This means that if you want to know where a certain medicine can be bought or the selling price of a certain medicine in different pharmacies, you don't have to go to the store in person, just swipe your phone and it will be clear at a glance. Users can access it through the local medical insurance bureau's App, WeChat applet, WeChat official account, Alipay applet and other channels, without registering for instant use. The role of the medical insurance drug comparison mini program, from local pilot to regional promotion, and then to comprehensive popularization, will continue to rise with the continuous expansion of the promotion scope. After entering the drug name in the "Price Comparison Tool", the public can click to view nearby pharmacies for sale. Not only can they see the drug code, specification and dosage form, production enterprise, approval number and other content that the public is concerned about, but they can also sort and filter according to distance and price. Drug prices are spread out in the sunshine, and consumers can compare prices from three different sources. Pharmacies can only sell drugs included in the comparison range at low profits, and dare not raise prices under the guise of information asymmetry like in the past, resulting in consumers buying high priced drugs without realizing it. In the past, there were also "comparison tools", how is it different from this one? The greater significance of the unified promotion of the "price comparison tool" in multiple provinces and cities lies in smoothing the inter provincial price differences of drugs. At present, there are unfair and discriminatory high prices of drugs among provinces. For example, the commonly used medicine folic acid tablets of a certain enterprise have a listed price of 12 yuan per bottle in most provinces across the country, but in some provinces, the listed price has reached over 30 yuan. If the "price comparison artifact" is only used for local comparisons within the city or province, it will be difficult to detect phenomena such as inter provincial discriminatory high prices. Comprehensively popularizing the "price comparison tool" for drugs is expected to achieve fair drug prices nationwide. From a developmental perspective, in the future, the "price comparison tool" for drugs can also expand other functions. For example, if the "price comparison tool" can be combined with drug traceability codes, it can allow the public to scan codes to supervise drugs while comparing prices, achieving the integration of price supervision and quality supervision. For example, adding a home delivery service function to the pharmacy comparison mini program allows people to quickly purchase the cheapest medical insurance drugs from nearby pharmacies at home. In addition, online drug purchases have already been reimbursed by medical insurance in many places, and in the future, online comparison and drug purchases can also achieve one click reimbursement by medical insurance. Despite the powerful and promising role of the "price comparison tool" for drugs, promotion still faces some challenges. At present, the price comparison mainly targets drugs within the medical insurance catalog, while patients' demand for price comparison of drugs and medical devices outside the catalog has not yet been met. In some places and for some drugs, the timeliness of updating drug price data is poor, and some pharmacies selectively report low-priced drugs and conceal high priced drugs. More importantly, many elderly people do not know how to use this mini program, so it is necessary to make aging friendly modifications to the "comparison tool" or launch an elderly version. By integrating functions to empower the drug "price comparison tool" once again, continuously expanding the coverage of price comparison, simplifying software operation processes... This convenient "tool" will be more down-to-earth, using its unique "divine power" to further squeeze out the moisture of drug prices, and combined with other convenient measures to build an integrated service system of "check compare purchase payment delivery", making the convenience and benefits obtained by the public in purchasing drugs more comprehensive and diverse.
