Although the slower driving habits of some seniors often steam impatient younger motorists, researchers at Johns Hopkins School of Medicine have found that elders who stay behind the wheel are less likely to enter nursing homes or assisted living centers than those who have never driven or who have given up driving altogether.
The Hopkins study findings, published in the July issue of the American Journal of Public Health, included extensive interviews conducted over a 10-year period with 1,593 seniors between 65 and 84 years of age who live in the small, Eastern Shore town of Salisbury, Md.
"We are not recommending continuation of driving for seniors who are a threat to themselves or others on the road," said Ellen Freeman, Ph.D., an epidemiological researcher now working with the Johns Hopkins Wilmer Eye Institute and the study's lead author. "Instead, we hope that understanding the very real health impact that losing the ability to drive has on seniors will encourage families to plan contingencies to assist elderly members with transportation issues."
The researchers also pointed out that losing the ability to drive poses an especially significant hardship to seniors living in isolated rural areas or any place without good, accessible public transportation for the elderly.
"We set out to learn whether or not the loss of driving ability played a measurable role in an older person's eventual need for long-term care," said Sheila West, Ph.D., a professor of ophthalmology at the Johns Hopkins School of Medicine. "The independence that accompanies a driver's license and car has long been linked anecdotally to a better quality of life for seniors."
Freeman and others on the Hopkins team stressed that from both a personal and public policy standpoint, the need is greater than ever to figure out what best and safely helps older people keep an independent lifestyle. "The average annual cost of nursing home admission is $69,000, and the price tag associated with entry into assisted living is roughly $30,000," she noted. "That's a public policy issue of huge dimensions as our population ages."
"This probably isn't so much about the process of driving but rather the larger issue of mobility as it relates to a person's independence," added Freeman. "When someone becomes a shut-in due to the loss of their primary transportation, the likelihood that they will require living assistance categorically increases."
Non-drivers across the entire age group studied had four times the risk of long-term care entry compared to drivers, and the absence of other drivers in the home doubled the risk of entering long-term care. Nine percent of those studied entered long-term care for three months or more. By the end of the study, 29 percent of men and 58 percent of women had no other drivers in the household, and 22 percent of people who were driving at the beginning of the study reported that they stopped driving during the study.
Freeman and her colleagues said their study methods took into account and factored out many other causes of "long-term care entry," including age, race, marital status and such health problems as frailty, dementia and stroke damage. There were no significant differences in outcomes between men and women.
"These findings point to the importance of research into how to keep seniors driving and independent as long as is safely possible," said West, director of the Johns Hopkins Initiative for Translational Research on Driving and the study's senior author.
Salisbury, the site of the 10-year study, is a semirural town of about 40,000 people. Freeman cautioned that because no formal public transportation system was available to the residents of the town, the findings of the study should only be interpreted as meaningful for communities of similar size that also lack public transportation infrastructure.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
