Americans are living longer and the average age of the population is growing. These factors are leading to an increased demand for healthcare.
A new study has found that some of the nation’s elderly are more prone to health issue than others.
“In America, nearly 4 in 5 elderly people have multiple chronic medical conditions,” reports Medical News Today. “Now, a new analysis assessing the burden of these multiple conditions on life expectancy finds that the more ailments a person has after retirement age, the shorter their life expectancy.”
The study, which was conducted by researchers at Johns Hopkins Bloomberg School of Public Health and published in the journal Medical Care, could shed some light on why life expectancies among older Americans are decelerating, MNT reported.
Here are some highlights from the study and MNT article:
· To conduct their analysis, the researchers, led by Eva H. DuGoff, used a nationally representative sample of Medicare beneficiaries who were enrolled as of January 1st, 2008. This involved the records of nearly 1.4 million people over the age of 67 with 21 defined chronic conditions. The team explains that in the US, life expectancy is rising more slowly than in other parts of the world. The obesity epidemic is largely to blame, as well as its associated health conditions, the researchers note. “Though a 75-year-old woman in the US with no chronic conditions will live an additional 17.3 years on average, the team found that a 75-year-old woman with five chronic conditions will only live an average of 12 years and a woman with more than 10 conditions will only live 5 more years.”
· Additionally, the analysis revealed that women still live longer than men, and white people live longer than black people. Commenting on their findings, DuGoff says: “Living with multiple chronic diseases such as diabetes, kidney disease and heart failure is now the norm and not the exception in the US. The medical advances that have allowed sick people to live longer may not be able to keep up with the growing burden of chronic disease.”
· The team found that what type of disease a person has plays a role. For example, a 67-year-old individual with heart diseasewill live an additional 21.2 years, whereas someone with Alzheimer’s disease is only expected to live an additional 12 years. Though life expectancy decreases by 1.8 years with each additional condition, the researchers say the impact increases with more diseases. “We tend to think about diseases in isolation,” says senior author Prof. Gerard F. Anderson, from Johns Hopkins. “You have diabetes or you have heart failure. But many people have both, and then some.”
Prof. Anderson adds:
“The balancing act needed for care for all of those conditions is complicated, more organ systems become involved as do more physicians prescribing more medications. Our system is not set up to care for people with so many different illnesses. Each one adds up and makes the burden of disease greater than the sum of its parts.”
The researchers conclude their study by noting that Social Security and Medicare planners may find their results helpful in making population and cost predictions for the future, adding that they “should account for the growing number of beneficiaries with multiple chronic conditions when determining projections and trust fund solvency.”
According to the team, 60 percent of Americans who are 67 and older have three or more chronic diseases.
At The Healthcare Institute, students of the Medical Assistant training program are prepared to work in a variety of settings, ranging from hospitals and doctor offices, to surgical centers and urgent care centers. Students are trained to prepare patients for examinations and other minor procedures, assist with treatments and record vital signs, and they also perform administrative tasks.
Students of The Healthcare Institute Medical Assistant training program are often able to start their new career in less than a year, and with the high demand for professionally trained Medical Assistants the prospects of landing a long-term career in this field have never been better.
The growth of urgent care facilities and the lack of doctors have put more clinical responsibilities on Medical Assistants, which is why it is extremely important for today’s Medical Assistants to receive the best training and experience. Medical Assistants have a lot of responsibilities and employers are most interested in student that have completed a professional training program, such as the Medical Assistant training program at The Healthcare Institute.
If you are looking for a career that offers good pay, is in high demand and is expected to grow, then becoming a Medical Assistant could be the right fit for you, especially as facilities like urgent care centers continue to increase across the country. However, the best way to enter this profession and establish a long-term career as a Medical Assistant is to receive professional training and instruction.
