Healthcare Economics: Why Prevention Costs Less Than Treatment
Healthcare Economics: Why Prevention Costs Less Than Treatment.
The adage that an ounce of prevention is a pound of cure has become a cliche in the health policy. However, most of the health systems in the world use more money on the treatment of sickness rather than prevention of sickness. Such a mismatch demonstrates that there is more to cost-saving arguments than meets the economic eye. In order to establish rational health policy and maintain medical expenditure sustainable we need to understand when prevention is actually cost reduction, when it leads to better outcomes at an affordable rate, and when treatment remains the optimal strategy to pursue.
The Economic Rationality of Prevention.
Preventive health care encompasses a great variety of activities: vaccines, screenings, counseling, environmental modifications, and health-related education. All these are meant to prevent the occurrence of disease or to detect it at an early stage when it is rather simple and cheap to treat. Prevention is economical because it prevents the need to spend money on advanced disease treatment, loss of work time and it provides individuals with a longer healthy life that contributes to the economy.
The vaccination demonstrates how prevention will save money. Vaccination of children against measles, polio and diphtheria prevents serious diseases that would require intensive treatment and leave them incapacitated. Research determines that vaccination initiatives are always profitable many folds, U.S. child immunizations save between 16 and 44 dollars on every dollar spent. Eradication of smallpox which was an international vaccination project eliminated the costs of treatment and created enormous humanitarian advantages.
This is more complex in preventing chronic disease. Approximately 75 percent of U.S. expenditure in healthcare goes to heart disease, diabetes, and cancer. Drugs such as statins or blood-pressure medications, lifestyle changes such as food, exercise and quitting smoking make the frequency and severity of these diseases less frequent and less serious. Prevention, though, can also enable people to live longer and living longer can create more conditions that need care in the future which can counteract the savings.
The compression of morbidity concept states that with healthy lifestyles, the onset of morbidity is delayed, reducing the period that an individual will be in ill health until the death of the body. In case this occurs, it is associated with obvious economic benefits: human beings will work more, less expensive end-of-life care will be required, and the quality of life is going to be better. It has been demonstrated that healthy individuals live long and healthier lives, although they consume considerable amounts of health care throughout their long lives. The saving of money or not depends on the way in which we measure the benefits of the future, the possibilities of increase of the costs of the treatment and the efficiency of the particular prevention programs.
Increasing costs where prevention is vital.
All prevention strategies are not cost-efficient and they actually increase expenditure of health care and yet increase the outcome. Screening is a good example. Breast cancer to mammograms, colon cancer to colonoscopies, and prostate cancer to PSA tests are the tests that decrease death, but at the same time, they generate high expenses due to the false positive, overdiagnosis, and treatments of tumors that otherwise would not have caused any problems. In cost-effectiveness analyses, such screenings are about to cost between $50,000 and $100,000 per quality-adjusted life year which is acceptable but not a net savings.
Behavioural prevention is not usually cost efficient. Diabetes can be prevented using intensive programs that assist individuals in losing weight, though consistent counseling, monitoring, and support. The fact that they have increased the number of years of healthy life results in decades of additional health spending. Such programs increase wellbeing and could be affordable with conventional willingness-to-pay levels, yet they do not reduce overall health expenditure as many people would imagine.
This is complicated by the fact that prevention paradox exists. Mass prevention requires a big number of individuals to take part, yet the share of risk decrease to each individual does not appear significant. Healthy citizens would be willing to pay health prevention as benefits will be primarily enjoyed by the few. This poses a challenge to any tax or insurance requirement that covers prevention. The most at risk people are the ones whose interests will benefit the most; they tend to engage the least due to poverty levels, lack of health literacy and mistrust on health institutions.
Market Failures and Barriers to implementation.
There are systematic barriers to even established cost-effective prevention. Prevention benefits are manifested in years or decades, whereas the costs are observed in the near future. Budgets and politics prefer acute care that can be seen instead of prevention on a long-term basis. Care is paid by health insurers and governments but not by patients who are the ultimate beneficiaries. It is a principal-agent problem that implies that the individuals who incur the expenses do not enjoy the benefits later.
Further hurdles are explained in behavioral economics. The current bias of people is that they are concerned with immediate expenses and inconveniencing instead of future health benefits. The tendency is optimism bias, which makes them see their risk of diseases as less than it is. Status-quo bias makes the wrong decisions the default. This is the reason that rational behaviors like exercise, diet, screening are rare, despite a person being aware that it will help.
Preventive capacity is restricted by the health work force and infrastructure. Medical training focuses on treatment and diagnosis but not on population health and counseling. Reimbursement mechanisms are based on the volume of procedures rather than on health results. Drug and equipment manufacturers are spending fortunes in advertising new therapies, which give greater returns than preventive strategies that have lesser returns.
Evidence-based Prevention Priorities.
Economic prudence suggests prevention measures which pay off most. Childhood interventions such as nutrition, vaccines, and early education are proven to be exceptionally cost-effective as children are more flexible and the gains are lifelong. Taxes on tobacco and smoke free legislation reduce the smoking rates inexpensively and upsurge tax income. Minimal investment is required to reduce drinking and its associated harms through brief alcohol counseling in primary care.
High-value preventive care services The services recommended by the U.S. Preventive Services Task Force have solid evidence. These are blood-pressure screening, colorectal cancer screening (age between 50-75), and intensive cardiovascular risk reduction counseling. They enhance results with expenses that are reasonable to the society, although they do not necessarily save money directly.
Low-value prevention- screening of prostate cancer to all men, annual physical exams of healthy adults, screening by whole-body images of individuals without symptoms- utilizes resources with no proportional benefit and may harm by over-diagnosis and overtreatment. This can be used to increase efficiency by reducing low-value care and increasing high-value prevention.
System Level Reform and Investment.
The health system should change in order to achieve the economic potential of prevention. Reforms of payment such as global budgets, capitation and shared savings will position incentives around population health rather than volume. The ACOs and integrated delivery systems assume the full patient cost, which motivates prevention discouraged in the fee-for-service systems.
Even with tightening of the budget, there must be consistent funding on the public health infrastructure. Surveillance of diseases, environmental surveillance, health education, and community health workers result in the benefits that cannot be realized by clinical medicine. These up-stream interventions address social determinants of health like housing, nutrition, education, employment, which are more influencing factors on the health than medical care itself.
A health in all policies system incorporates prevention in every aspect of the government. Non-health measures such as transportation that encourages walking and biking, agricultural policies that encourage healthy food, and urban design that encourages pollution prevention all help in prevention of disease. These healthy-by-design policies in many cases come with co-benefits, such as reduced emissions, improved social cohesion, and increased productivity, that make prevention investment a focus of political support.
