Improving Value of US Healthcare ExpendituresIncreased purchaser focus on:• Improving value of expenditures

• Reducing waste

• Improving health outcomes for beneficiaries

• Preventing chronic illness and complications

Two main levers • Health plan design

• Delivery system design

Cost-Sharing and HealthImpact of larger cost-shares on chronic disease self-management

Chronic disease the major driver in health care costs

Re-consideration of indiscriminate cost-sharing

• Consumer holds the early short term risk

• Purchaser/health plan holds the longer term risk

Value-based Cost-SharingFirst iterations:• Preventive service coverage

• Tiered pharmacy benefits

Generics

Brand-name

Non-preferred and non-formulary

Most recent efforts focused on pharmacy cost-sharing: reducing cost-shares• Pitney Bowes

• University of Michigan employees

Science of Value-Based DesignLarge body of evidence on impact of increased cost-shares• Tends to be focused on discrete services

Much smaller literature on impact of reducing cost sharesEven smaller literature on impact of cost-sharing on health outcomes and productivityTiny literature using control group with multiple outcomes

Worksite WellnessAnother approach to reducing costs and improving health• Focus on lifestyle change

Incenting health behavior

Healthy work environments

Change of work culture

• Outcomes of interest

Health status and utilization

Absenteeism and presenteeism

Productivity

• 77% of large employers offer these services

• Health risk assessments are entry portal for engagement

Group Health’s Total Health Plan for EmployeesEmployer Aims• Improve productivity through

Better health of staff

Decreased absences

Improved on-the-job productivity

• Decrease health expenditure trend rate

Mechanism• Incent healthy behaviors and improved chronic disease control through

monetary incentives and value-based health benefit pricing

• Reinforce culture of self-awareness, accountability and reporting of health and health behaviors through monetary incentives and culture change

Specific AimsTo assess the impact of the new value-based insurance design on:

PRIMARY: changes over time in employee self-reported:

• health status

• absenteeism due to illness and disability

• presenteeism (i.e. lost productivity time at the workplace)

SECONDARY: • clinical quality scores for chronic illness care and preventive

screenings,

• lifestyle behavioral risk factors,

• employee satisfaction with health benefits,

• health services utilization by employees, and

• employer-paid health costs for the employee population.

Total Health – participation• >80% of all staff and spouses/domestic partners on the TH medical plan have taken the HRA•73% are earning points on the wellness website

Progress to DateBaseline survey completed early 2010• Group Health: 70% response rate• KPCO: 60% response rate

Permissions to link survey data• Approximately 60-64% agree to linkage with HR and/or medical

data

Challenges and StrengthsPrivacy issues/concerns• Employer is also provider of care

• Key engagement of organized labor units

Validity of self-reported dataStudy design and potential for confounding• Use of highly similar control group external to Group Health
