Brownspeed Health Care (BHC), based in Orlando, Florida, provided a wide range of consultative services
to the US health care industry. Recent social and political issues in the US health care system, along with
near-record employment levels, led to a high rate of employee turnover throughout the industry. Employee
n
turnover cost the health care sector billions of dollars each year in direct replacement expenditures (e.g.,
recruiting, training, and integration). These estimates did not include the added financial impact associated

1. What are some of the key challenges associated with time series forecasting, especially as they
apply to the dynamic health care sector?
Time series forecasting is a subset of predictive analytics. It consists of a family of mathematics-based
e
techniques that can be used to predict future events using past data. Time series forecasting is based on the
pl
fundamental assumption that future patterns will be like historical trends.
Making predictions about future events based on the past is often referred to as extrapolation. The accuracy
m
of time series forecasting models tends to degrade when structural changes occur in the underlying data.
For example, the transition to national health care insurance could significantly alter patterns in the number
Sa
of new hospital admissions.6 In these situations, more sophisticated modelling techniques are often
required, such as relational predictive analytics.
Some specific challenges associated with health care forecasting include the reliability and limitations of
