Advances in public health in this first decade of the 21st Century have contributed to a record low death rate in the U.S. and the continuation of a steady downward trend.
From 1999 to 2009, the age-adjusted death rate in the United States declined from 881.9 per 100,000 population to 741.0, a record low.
Contributing factors for the advances in public health include the development of new vaccines, awareness campaigns, health screening, new legislation and preparedness.
Public health scientists at the Centers for Disease Control and Prevention, were asked to nominate noteworthy public health achievements that occurred in the United States during 2001 – 2010. From those nominations, 10 achievements, not ranked in any order, have been identified.
Vaccine-Preventable Diseases
The past decade has seen substantial declines in cases, hospitalizations, deaths, and health-care costs associated with vaccine-preventable diseases. New vaccines were introduced, bringing to 17 the number of diseases targeted by U.S. immunization policy.
A recent economic analysis indicated that vaccination of each U.S. birth cohort with the current childhood immunization schedule prevents approximately 42,000 deaths and 20 million cases of disease, with net savings of nearly $14 billion in direct costs and $69 billion in total societal costs.
Prevention and Control of Infectious Disease
Improvements in state and local public health infrastructure along with innovative and targeted prevention efforts yielded significant progress in controlling infectious diseases. Examples include a 30 percent reduction from 2001 to 2010 in reported U.S. tuberculosis cases and a 58 percent decline from 2001 to 2009 in central line–associated blood stream infections.
Other major advances include the capacity to identify contaminated foods rapidly and accurately and prevent further spread; expanded HIV screening of persons aged 13–64 years, and new blood donor screening for the West Nile virus. To date, such screening has interdicted 3,000 potentially infected U.S. donations, removing them from the blood supply.
Tobacco Control
By 2009, 20.6 percent of adults and 19.5 percent of youths were current smokers, compared with 23.5 percent of adults and 34.8 percent of youths 10 years earlier. However, progress in reducing smoking rates among youths and adults appears to have stalled in recent years.
Although no state had a comprehensive smoke-free law (i.e., prohibit smoking in worksites, restaurants, and bars) in 2000, that number increased to 25 states and the District of Columbia (DC) by 2010, with 16 states enacting comprehensive smoke-free laws following the release of the 2006 Surgeon General’s Report.
In 2009, the largest federal cigarette excise tax increase went into effect, bringing the combined federal and average state excise tax for cigarettes to $2.21 per pack, an increase from $0.76 in 2000. By 2010, FDA had banned flavored cigarettes, established restrictions on youth access, and proposed larger, more effective graphic warning labels that are expected to lead to a significant increase in quit attempts.
Maternal and Infant Health
The past decade has seen significant reductions in the number of infants born with neural tube defects (NTDs) and expansion of screening of newborns for metabolic and other heritable disorders. Mandatory folic acid fortification of cereal grain products labeled as enriched in the United States beginning in 1998 contributed to a 36 percent reduction in NTDs from 1996 to 2006 and prevented an estimated 10,000 NTD-affected pregnancies in the past decade, resulting in a savings of $4.7 billion in direct costs.
Improvements in technology and endorsement of a uniform newborn-screening panel of diseases have led to earlier life-saving treatment and intervention for at least 3,400 additional newborns each year with selected genetic and endocrine disorders. Newborn screening for hearing loss increased from 46.5 percent in 1999 to 96.9 percent in 2008.
Motor Vehicle Safety
Motor vehicle crashes are among the top 10 causes of death for U.S. residents of all ages and the leading cause of death for persons aged 5 to 34 years. In terms of years of potential life lost before age 65, motor vehicle crashes ranked third in 2007, behind only cancer and heart disease.
From 2000 to 2009, the death rate related to motor vehicle travel declined from 14.9 per 100,000 population to 11.0, and the injury rate declined from 1,130 to 722; among children, the number of pedestrian deaths declined by 49 percent, from 475 to 244, and the number of bicyclist deaths declined by 58 percent, from 178 to 74.
These successes largely resulted from safer vehicles, safer roadways, and safer road use. Behavior was improved by protective policies, including effective seat belt and child safety seat legislation; 49 states and the DC have enacted seat belt laws for adults, and all 50 states and DC have enacted legislation that protects children riding in vehicles.
Cardiovascular Disease Prevention
Preliminary data from 2009 indicate that stroke is now the fourth leading cause of death in the United States. During the past decade, the age-adjusted coronary heart disease and stroke death rates declined from 195 to 126 per 100,000 population and from 61.6 to 42.2 per 100,000 population. Factors contributing to these reductions include declines in the prevalence of cardiovascular risk factors such as uncontrolled hypertension, elevated cholesterol, and smoking, and improvements in treatments, medications, and quality of care.
Occupational Safety
Significant progress was made in improving working conditions and reducing the risk for workplace-associated injuries. For example, patient lifting has been a substantial cause of low back injuries among the 1.8 million U.S. health-care workers in nursing care and residential facilities. In the late 1990s, an evaluation of a best practices patient-handling program that included the use of mechanical patient-lifting equipment demonstrated reductions of 66 percent in the rates of workers’ compensation injury claims and lost workdays and documented that the investment in lifting equipment can be recovered in less than 3 years.
The annual cost of farm-associated injuries among youth has been estimated at $1 billion annually. A comprehensive childhood agricultural injury prevention initiative was established to address this problem, resulting in a 56 percent decline in youth farm injury rates from 1998 to 2009.
Cancer Prevention
Evidence-based screening recommendations have been established to reduce mortality from colorectal cancer and female breast and cervical cancer. From 1998 to 2007, colorectal cancer death rates decreased from 25.6 per 100,000 population to 20.0 (2.8 percent per year) for men and from 18.0 per 100,000 to 14.2 (2.7 percent per year) for women. During this same period, smaller declines were noted for breast and cervical cancer death rates (2.2 percent per year and 2.4 percent, respectively).
Childhood Lead Poisoning Prevention
In 2000, childhood lead poisoning remained a major environmental public health problem in the United States, affecting children from all geographic areas and social and economic levels. In 1990, five states had comprehensive lead poisoning prevention laws; by 2010, 23 states had such laws. Findings of the National Health and Nutrition Examination Surveys from 1976 to 1980 to 2003 to 2008 reveal a steep decline, from 88.2 percent to 0.9 percent, in the percentage of children aged 1 to 5 years. The economic benefit of lowering lead levels among children by preventing lead exposure is estimated at $213 billion per year.
Public Health Preparedness and Response
After the international and domestic terrorist actions of 2001 highlighted gaps in the nation’s public health preparedness, tremendous improvements have been made. In the first half of the decade, efforts were focused primarily on expanding the capacity of the public health system to respond (e.g., purchasing supplies and equipment). In the second half of the decade, the focus shifted to improving the laboratory, epidemiology, surveillance, and response capabilities of the public health system.
During the 2009 H1N1 influenza pandemic, these improvements in the ability to develop and implement a coordinated public health response in an emergency facilitated the rapid detection and characterization of the outbreak, deployment of laboratory tests, distribution of personal protective equipment from the Strategic National Stockpile, development of a candidate vaccine virus, and widespread administration of the resulting vaccine. These public health interventions prevented an estimated 5 to 10 million cases, 30,000 hospitalizations, and 1,500 deaths (CDC, unpublished data, 2011).
