…so that, function is improved…

… and quality of life improves…

…and health care cost and utilization reduces

The approach is to…

If you maintain the health and well being of currently healthy members (employees, patients)…

…quality of life stays high

…health care cost and utilization stays low

…disability is prevented

…productivity stays high

…excess costs are avoided.

Furthermore…

So, why is it so hard to prove the value of

prevention?

LOOKING BACK…focused on the futureLOOKING BACK…focused on the future

Disease is preventable;

Modifiable health risk factors occur prior to disease onset;

Many modifiable health risks are associated with increased health care costs;

Modifiable health risks can be improved;

Improvements in health risks can lead to reductions in health costs;

Improvements in health risks can lead to improvements in productivity;

Well-designed and well-implemented programs can save more money than they cost (positive ROI)

The Logic Flow

Page 9: St. John’s, Newfoundland, Canada June 28-29, 2005

LOOKING BACK…focused on the futureLOOKING BACK…focused on the future

1. A large proportion of diseases and disorders is preventable. Modifiable health risk factors are precursors to a large number of diseases and disorders and to premature death (Healthy People 2000, 2010, Amler & Dull, 1987, Breslow, 1993, McGinnis & Foege, 1993).

2. Many modifiable health risks are associated with increased health care costs within a relatively short time window (Milliman & Robinson, 1987, Yen et al., 1992, Goetzel, et al, 1998, Anderson et al., 2000, Bertera, 1991, Pronk, 1999).

3. Modifiable health risks can be improved through workplace sponsored health promotion and disease prevention programs (Wilson et al., 1996, Heaney & Goetzel, 1997, Pelletier, 1999).

4. Improvements in the health risk profile of a population can lead to reductions in health costs (Martinson, et al., 2003, Edington et al., 2001, Goetzel et al., 1999).

5. Worksite health promotion and disease prevention programs save companies money in health care expenditures and produce a positive ROI (Johnson & Johnson 2002,Citibank 1999-2000, Procter and Gamble 1998, Chevron 1998, California Public Retirement System 1994, Bank of America 1993, Dupont 1990).

Medical STD

• Improving health risks contains escalating medical costs and improves productivity (esp. STD costs)

• Largest reduction in costs experienced in those moving from high-risk to low-risk

• Total 2-year costs for groups was follows:

• H-H = $6,942• H-L = $3,919• L-H = $3,897• L-L = $2,477

• Those who remain at low risk maintain the best cost and productivity profile

• Note: Risk assessed by HRA; linked to medical and STD costs for the years 1998-1999 compared to 2000-2001

• Statistical adjustment for age, gender, co-morbidity, smoking, BMI

Change in Mean Annual Total Charges

• Increased PA among older adults is associated with lower annual health care charges within 2 years (1994-1995 to 1996-1997) as compared to continuously inactive controls

• Among those who increase PA from 0-1 to 3+ days per week, decline in costs is as much as ~$2,200

• Such cost savings easily justify investments in PA programs
