Introduction
Ø Costs for health care increase faster than GDP, health
insurance premiums increase faster than personal net
income.
GDP = Gross domestic product
The Impact of Demographic Change on Health Insurance Costs

Introduction
Ø Causes of this development
• Increasing supply of health care due to - More frequent claims - Augmented treatment costs- Medical progress- Increasing number of health care professionals and
facilities
• Increasing demand of health care due to- Demographic change- Claims inflation.

Introduction
The Impact of Demographic Change on Health Insurance Costs
Ø Focus on relation between demographic change and health insurance outlays.
Ø Examination of the following thesis:An increased life expectancy does not have any influenceon the costs of health insurance due to the following reason: a large share of total life-time individual health care expenditure is spent during the last months of life. It is irrelevant for health care spending if such costs appear for a person at the age of 60 or 90.

The Impact of Demographic Change on Health Insurance Costs
Consequences of Demographic Change
Ø Two opposing theses:
• Compression of morbidity:Life expectancy increases, but the period of time of morbidity before death decreases.
• Extension of morbidity:Life expectancy increases, but the period of time of morbidity increases as well.

The Impact of Demographic Change on Health Insurance Costs
Consequences of Demographic Change
Ø Steeper cost/expenditure profiles in health insurance.
A cost/expenditure profile indicates the - on a fixed age -standardized claim per capita paid for health care. The escalation of those costs over time shows that elderly insureds become more cost-intensive than younger age-groups.

Consequences of Demographic Change
Ø Steeper cost/expenditure profiles in health insurance have three main reasons:
• Higher medical costs in particular for elderly patients.
• Higher incidence of geriatric diseases e. g. Dementia (Alzheimer’s disease), Parkinson’s disease, Cancer.
• Deterioration of the state of elderly people’s health.

The Impact of Demographic Change on Health Insurance Costs
Consequences of Demographic Change
Ø Connection between the two theses and steeper cost/expenditure profiles in health insurance (SCP):
• Compression of morbidity ó SCP- Constant health costs in the period of time: No (negative) effect on cost
profiles and decrease in health insurance costs of elderly people.- Increasing health costs over the course of time: Net effect on cost
profiles uncertain (either reduction of duration of treatment (morbidity) or increase in intensification and in price of medical treatment).
• Extension of morbidity ó SCP- Increase in duration of treatment ⇒ higher health costs
⇒ negative effect on cost profiles.

Analysis of Two DKV Portfolios
Ø Study of two medical expenses insurance tariffs for out-patient and in-patient treatment.
Ø Study of a section of both portfolios meeting the following three conditions:• People have been insured with DKV since before 1990.• People were insured with the same tariff between 1993 and
1999.• The moment of death on average was in the middle of
the year 1999.
The Impact of Demographic Change on Health Insurance Costs
12
Analysis of Two DKV Portfolios
Ø Study of three different portfolios:survivors, deceased in 1999 and the entire portfolios.• 5-year age-groups from age 40 to 99.• Large number of insured people representative of the entire
population (1999) concerning distribution among age, region and deceased, apart from sex.
Ø Comparison of health costs caused by the insureds who survived with those who died in 1999.

13
Analysis of Two DKV Portfolios
Ø Claims per capita over the course of time anddependent on age
• Analysis in two dimensions: time and age.• Claims per capita standardized on the age-group
45 to 49.• Comparison of the portfolio with and without the
deceased.• Calculation of the gradient-coefficient of a straight
regression line.

Analysis of Two DKV Portfolios
Ø Claims per capita over the course of time anddependent on age
Interpretation of the results:• No significant differences between the development of the
cost profiles over the course of time for the portfolio with or without the deceased (for the in-patient and out-patient tariff).⇒ Unchanged high level of health insurance costs
even if the intensive medical treatment of the elderlyinsureds immediately before death is not taken intoaccount.

Analysis of Two DKV Portfolios
Ø Claims per capita over the course of time anddependent on age of the two tariffsInterpretation of the results:
⇒ Proves thesis of extension of morbidity.⇒ No shift of health insurance costs into the future
in case of rising life expectancy.(Disproportionate rise of health insurance costs).
⇒ Steeper cost profiles reduce the financialstability of the health insurance systems as a result ofdemographic change.

Analysis of Two DKV Portfolios
Ø Claims per capita of the portfolio with and without deceased dependent on age
Results: • In-patient tariff:
- Health costs with deceased are always higher than without deceased.
- The cost profile is steeper.• Out-patient tariff:
- The cost profile with deceased is flatter than without deceased.

Ø Claims per capita of the portfolio with and without deceased dependent on age
Interpretation of the results: • Insignificant differences between the cost profiles of the
portfolio with and without deceased for the in-patient and the out-patient tariff.⇒ Elderly insureds cause high claims independent of
proximity to death due to typical geriatric diseases and improved possibilities of medical treatment. .
⇒ Increase in frequency of geriatric diseases because ofhigher life expectancy.

Analysis of Two DKV Portfolios
Ø Claims per capita of insureds who submitted a claim in entire portfolio according to age and over the course of time
Interpretation of the results: • In-patient treatment of deceased became more expensive
than of survivors for all age-groups over the course of time⇒ Intensification of medicine especially in the field
of hospital treatment and for critically ill people shortly before death.
⇒ Proves thesis of extension of morbidity(not detectable in the field of out-patient treatment).

Ø Calculation of ratio of claims per capita of deceased and survivors who submitted a claim per age-group in 1999.
Results: • Decrease of the ratio of deceased and survivors who
submitted a claim with advancing years with the consequence of adjustment of claims for both groups.

Analysis of Two DKV Portfolios
Ø Claims per capita of insureds who submitted a claim in entire portfolio according to age:Comparison of deceased and survivors
Results: • The claims of survivors exceed the claims of deceased
especially for the insureds of advanced years in 1999 ⇒ Less efforts for treatment of critically ill elderly people.
• Development of claims of survivors contrary to the development of claims of deceased with advancing years.

Ø Claims per capita of insureds who submitted a claim in entire portfolio according to age:Comparison of deceased and survivors
Interpretation of the results: • The ratio of claims per capita of deceased and survivors
converges to one with advancing years; considerably high health costs generated even by less seriously ill survivors.⇒ Deceased claim in-patient benefits in particular;
not only deathly sick insureds cause enormoushealth insurance costs.
⇒ Financial stress for health insurance systems.

Analysis of Two DKV Portfolios
Ø Development of claims of deceased in 1999
Ø Closer examination of the development of claims per capita of two older age-groups (75 to 79, 85 to 89 respectively).
Results:• In-patient tariff: Deceased in 1999 generated considerably higher
health costs within the last six years before death – especially in the 75 to 79 age-group.
• Examination of the claims only of deceased in 1999; we left out of consideration that some survivors certainly died within the following years (examination of the moment).

Analysis of Two DKV Portfolios
Ø Development of claims of deceased in 1999
Interpretation of the results:• Deceased in 1999 generated considerably higher health
costs not only in the last two but also within the last six years before death. The claims per capita of the elderly survivors increase evidently with advancing years.⇒ Rising life expectancy has a raising effect on
health insurance costs.
The Impact of Demographic Change on Health Insurance Costs
41
Conclusions
Ø High health insurance costs are not primarily influenced by the deceased.
Ø Disproportionate inflation of health insurance costs with advancing years is particularly dependent on age and not on the proximity to death.
Ø Steeper cost profiles over the course of time(especially for the in-patient tariffs)• Effect is not only caused by insureds shortly before death.• Comparable development for the portfolio with and without
deceased.
The Impact of Demographic Change on Health Insurance Costs
42
Conclusions
Ø Insignificant difference between the claims per capita of the portfolio with and without deceased.• Out-patient tariff: Difference independent of age.• In-patient tariff: Slight increase with advancing years.
Ø Increase in share of insureds who submitted a claim over the course of time – especially for the in-patient tariff.
Ø Increase in share of all insureds – survivors and deceased -who submitted a claim with advancing years – for the in-patient tariff in particular.
The Impact of Demographic Change on Health Insurance Costs
43
Conclusions
Ø Out-patient tariff:The claims per capita of the survivors who submitted a claim are considerably higher than the claims per capita of the deceased who submitted a claim.
Ø In-patient tariff:The deceased who submitted a claim cause lower claims per capita than the survivors who submitted a claim.
Ø Disproportionate increase in health insurance costs of the treated deceased compared with the treated survivors over the course of time (observation period 1993 to 1999).
The Impact of Demographic Change on Health Insurance Costs
44
Conclusions
Ø In-patient tariff:Deceased in 1999 already generated considerably higher health costs several years before death.
Ø Out-patient tariff:Nonuniform picture.
Ø Out-patient tariff:Financial stress due to higher life expectancy cannotbe directly derived from the above-mentioned results.
Ø In-patient tariff:Longer life expectancy and other factors like progress in medical technology pose a severe threat to the financial stability of health insurance.
