Utilizing cloud technology, the National Health Insurance Administration (NHIA) established the patient-oriented "PharmaCloud System" in July 2013, which collects and stores patient medication records in cloud-based databases and provides doctors and pharmacists with real-time access to patients' detailed medication records over the previous three months. The system enables doctors to reach diagnoses while avoiding duplicate prescriptions and preventing patients from taking duplicate medication, thereby greatly enhancing patient medication safety.

Following the implementation of the "PharmaCloud System," the 2015 rates of cross-hospital duplicate medication for patients administered with the six major outpatient medications (hypotensors, hypolipidemics, hypoglycemics, medication for schizophrenia, depression and hypnotic tranquilizers) were down 30% to 50% from 2014, according to the NHIA. It is estimated that around NTD 10.4 billion in medication expenditure has been saved in 2015, thanks to the synergy of outpatient doctors provided with access to the "PharmaCloud System" as well as routine audits and the screening and deduction of duplicate medication. Patients achieve better health by taking correct medications and are alleviated from the strain of excess medication, which also contributes to the anti-waste mechanism.

Effective from 2016, the "PharmaCloud System" has been expanded into the "Health Insurance Medical Information Cloud Inquiry System" in order to achieve continuous advancement, expand the scope of accessible medical care information as well as enhance system functionality. In addition to the existing categories of "Patient Medication Records" and "Controlled Substances," new inquiry items including "Examinations and Tests," "Surgical Operation Details," "Medication Records for Coagulation Factors," "Medication Records for Allergies," "Cautionary Medication Substances for Patients over 65 Years Old," "Dental Treatment & Surgical Operation Items," "Rehabilitation Medical Care Items," and " Medication Records of Chinese Medicine" have been added to provide additional safeguards as well as to ensure the comprehensive medical safety of the general public.

Medical institutions in Taiwan are highly concentrated in terms of geographical location, making it easier for people to seek medical assistance. It is quite common for patients to seek medical advice from multiple institutions, resulting in incomplete personal medical records that are scattered among different institutions. The NHIA would like to remind individuals who seek medical help as well as relatives of patients to proactively ask their doctors or pharmacists to access the "Health Insurance Medical Information Cloud Inquiry System" in order to fully utilize the medical records and inquiry outcome data saved on the NHIA cloud-based database to safeguard their personal health.
