Healthcare care providers and health plan organizations involved in accountable care consider analytics applications their top investment priority, according to a new report by IDC Health Insights. In IDC's survey of 40 hospitals and 30 insurers, 50% of respondents said their highest investment priority was advanced analytics. Forty-six percent were placing their chips on data warehousing, which is closely associated with the use of analytics. The latter figure is higher than that in a 2011 survey by HIMSS Analytics, which found that only 30% of healthcare providers had data warehouses. But the IDC number includes health insurers, most of whom have data warehouses, noted Cynthia Burghard, IDC's research director of accountable care IT strategies, in an interview with Information Week Healthcare.
