Hypertension is the most significant risk factor for cardiovascular disease and mortality worldwide, affecting 1.3 billion adults. Global disparities in hypertension control are widening with low- and middle-income countries (LMIC) having the fastest growing rates of hypertension and low rates of control.

Background: The drug supply chain is global and at risk of disruption and subsequent drug shortages, especially during unanticipated events.

Objective: Our objective was to determine the impact of coronavirus disease 2019 (COVID-19) on drug purchases overall, by class, and for specific countries.

Methods: A cross-sectional time series analysis of country-level drug purchase data from August 2014 to August 2020 from IQVIA MIDAS was conducted.

Background: Opioid analgesics play a key role in pain management but providing access while mitigating risk of misuse and dependence remains a challenge. Tracking global consumption of all opioids over time can help identify emerging patterns and drivers of use.

Methods: Prescription opioid analgesic consumption was estimated for 76 countries between 2009 and 2019 using IQVIA MIDAS data.

Rising health care spending has sparked new efforts to constrain health care expenditures. To explore how health care spending is distributed across consumers and how utilization patterns compare across health care resource expenditures (eg, hospital, outpatient care). Using the IQVIA PharMetrics Plus database, we conducted a retrospective claims analysis for the 2018 plan year to examine commercial health care spending and utilization across 5 settings of care: ambulatory services, inpatient services, office visits, pharmacy services, and additional services.

A large proportion of biomedical research and the development of therapeutics is focused on a small fraction of the human genome. In a strategic effort to map the knowledge gaps around proteins encoded by the human genome and to promote the exploration of currently understudied, but potentially druggable, proteins, the US National Institutes of Health launched the Illuminating the Druggable Genome (IDG) initiative in 2014. In this article, we discuss how the systematic collection and processing of a wide array of genomic, proteomic, chemical and disease-related resource data by the IDG Knowledge Management Center have enabled the development of evidence-based criteria for tracking the target development level (TDL) of human proteins, which indicates a substantial knowledge deficit for approximately one out of three proteins in the human proteome.
