MedicalResearch.com: What is the background for this study? What are the main findings?

 Response: The D-Prescribe trial was driven by the need to show that seniors can cut down on their medication in a safe and effective manner. Pharmacists intervened in a proactive way to flag patients who were on potentially risky meds such as sleeping pills, NSAIDs and glyburide and to inform them of the risks, using an educational brochure. Pharmacists also communicated with their physician using an evidence-based pharmaceutical opinion to spark conversations about deprescribing. As a result, 43% of patients succeeded in discontinuing at least one medication over the next 6 months.

MedicalResearch.com: What is the background for this study?

Response: The World Organisation (WHO) estimate that one-third of older adults aged 65 and over have a disabling hearing loss. Increasingly, research is finding that age-related hearing loss (ARHL) may be associated with other negative health outcomes, including dementia which currently affects 50 million people worldwide.

A study recently published in The Lancet reported that of nine possible modifiable risk factors, addressing age-related hearing loss (ARHL) could potentially lead to the largest reduction in the prevalence of dementia globally.

MedicalResearch.com: What is the background for this study?

 

Response: This study was a true team effort. It was funded by AARP and AARP Services, INC and the research was a collaboration of representatives from Johns Hopkins University, OptumLabs, University of California – San Francisco, and AARP Services, INC. Given all of the resent research on downstream effects of hearing loss on important health outcomes such as cognitive decline, falls, and dementia, the aim was to explore how persons with hearing loss interacted with the healthcare system in terms of cost and utilization.

MedicalResearch.com: What are the main findings? 

Response: Over a 10 year period, untreated hearing loss (hearing aid users were excluded from this study as they are difficult to capture in the claims database) was associated with higher healthcare spending and utilization. Specifically, over 10 years, persons with untreated hearing loss spent 46.5% more, on average, on healthcare (to the tune of approximately $22000 more) than those without evidence of hearing loss. Furthermore, persons with untreated hearing loss had 44% and 17% higher risk for 30-day readmission and emergency department visit, respectively.

Similar relationships were seen across other measures where persons with untreated hearing loss were more likely to be hospitalized and spent longer in the hospital compared to those without evidence of hearing loss.  Continue reading

MedicalResearch.com: What is the background for this study? What are the main findings? 

Response: Very old adults, those aged 85 and older, are the fastest growing age group in most western societies and are more likely to develop disability. Dietary protein is a sensible candidate because it may slow decreases in muscle mass and functional decline with aging. Although we know that protein intake is, on average, lower in older adults (a mean of 66 grams per day) compared to younger adults (a mean of 91 grams per day), research exploring protein intake and disability progression in very old adults is limited. We found that our participants from North-East England had four different disability trajectories between the ages of 85 and 90: a) a constant very low disability trajectory (difficulty with none or 1 activity of daily living (ADL))  over the 5 years; b) a low disability trajectory (difficulty with 2 ADLs) that steadily progressed to mild disability (5 ADLs); c) a mild disability score (4 ADLs) at 85 that increased to moderate disability (10 ADLs) by age 90; and d) a moderate disability score (9 ADLs) at baseline that progressed to severe disability (14 ADLs) after 5 years. We found that those with higher protein intake, especially those at or above 1 g per kg of body weight per day (70g of protein per day for a 70 kg person), were less likely to belong to a worse disability trajectory.

MedicalResearch.com: What is the background for this study?

Response: Loneliness is associated with poor health, reduced quality of life, and increased mortality. Loneliness typically worsens with age. We were curious to learn what the prevalence of loneliness was among older New Zealanders, if there were age-specific associations with loneliness, whether there were any associations between demographic and psychosocial variables and loneliness, and we also wanted to compare centenarians (100 years or older) with elderly people (aged 65-99 years). Centenarians are a particularly interesting group to study because they are a model of successful ageing.

The international Resident Assessment Instrument-Home Care (interRAI-HC) assessment has been mandatory in New Zealand for anyone undergoing assessment for publically funded support services or residential care since 2012, providing us with a comprehensive data set. We conducted a retrospective, observational, cross-sectional review of the interRAI-HC data from over 70,000 people living in the community who had their first assessment during the study period (January 2013-November 2017). We analysed eight items from the interRAI-HC data set to describe the population and evaluate the core psychosocial components of aging; age, gender, ethnicity, marital status, living arrangements, family support, depression and loneliness.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Older adults commonly take multiple medications. All medications carry the potential for both benefit and harm. When a medication is started a decision has been made between the healthcare professional and the patient that the likely benefits outweigh the potential risks. But over time the potential benefits and harms can change. So, part of good clinical care is discontinuation of medications when the benefit no longer outweighs the risks – for example when it is no longer needed or high risk. This is called “deprescribing”.

Previously we knew that older adults could have mixed feelings about their medications, that is, they believe that all their medications are necessary but also feel that they are a burden to them. Qualitative research has explored this further, finding that there are a number of barriers and enablers to deprescribing from the patient perspective. For example, someone might have fear of deprescribing because they are worried that their symptoms may come back. But if they know that deprescribing is a trial and they will be monitored and supported by their physician or other healthcare professional they might be more open to deprescribing.

From the physician perspective, there were concerns that older adults and their families were resistant to deprescribing and so there was fear that discussing possible medication discontinuation could damage the doctor-patient relationship.

In this study of almost 2000 older adults in the United States, we found that over 90% were willing to stop one of more of their medications if their doctor said it was possible. Additionally, one third of participants wanted to reduce the number of medications that they were taking.  Continue reading

Critical Illness Linked To Brain Changes Associated with Cognitive Decline

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: This study was conducted in response to anecdotal accounts and scientific evidence which suggests that major medical conditions, such as critical illness and severe infections, can have a long-term neurological effect on some individuals.

There are quite a few studies to date which have found that critical illnesses, such as severe sepsis, are associated with long-term cognitive impairment. Based on this evidence, we wanted to figure out to what degree critical illness and major infection may affect later brain structure and to determine whether the structural changes associated with these events were similar to those observed in Alzheimer’s disease.

Our main finding was that individuals who had one or more critical illness or major infection major infection during the decades leading up to older adulthood were more likely to have smaller brain volumes in brain regions most vulnerable to Alzheimer’s disease.

Most Health Care Costs Associated With Osteoporotic Fractures Occur in First Year

Pardee RAND Graduate School 

MedicalResearch.com: What is the background for this study? What are the main findings? 

Response: The economic burden of osteoporotic fractures is substantial with studies estimating the annual healthcare cost burden between $10 to 17 billion. Although estimates from individual studies vary, most studies assessing costs after a fracture only explore up to twelve months following a fracture. There is little investigation of how fracture patients’ costs evolve over a longer post-fracture period.

As osteoporotic fractures are one of the most common causes of disability among older adults and can translate into greater medical costs, we focused on studying Medicare beneficiaries. In fact, previous research has suggested that most of the increase in Medicare spending over time can be explained from costs associated with treating higher risk Medicare beneficiaries.

Our objective in this study was to compare health care costs over a 3-year period of those who experienced a fracture to those who did not among a sample of Medicare beneficiaries who were at an increased risk of having a fracture.

Consistent with previous studies, we found a significant increase in expenditures in the year immediately following a fracture relative to controls: almost $14,000 higher for fractures relative to controls. However, at 2 and 3-years post-fracture, there were no significant differences in the change in expenditures between fracture cases and controls. We note that these findings may be different for beneficiaries living in skilled nursing facilities or other non-community-based settings.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Previous studies have shown that offspring of long-lived parents are not only likely to live longer but to also avoid major chronic diseases (e.g., coronary heart disease), have fewer chronic disease risk factors, and to have better cognitive and physical function in late life. However, few studies have examined parental longevity in relation to an overall measure of successful aging that included reaching old age free of both major diseases and disabilities.

The objective of our study was to determine if parental longevity predicted healthy aging, defined as survival to age 90 without any major age-related diseases (coronary heart disease, stroke, diabetes, cancer, or hip fracture) or physical limitations. The participants of our study were from the Women’s Health Initiative, a large, longitudinal study among postmenopausal women from the United States.

We observed that women whose mothers survived to at least age 90 years were 25% more likely to achieve healthy aging. We also observed that women whose fathers only lived to age 90 did not have increased likelihood of healthy aging. However, women whose mother and father both lived to age 90 were the most likely to achieve healthy aging.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Randomized trials are the best evidence basis we have to treat patients. It is known for more than 20 years that older adults and women are disproportionately excluded from randomized trials in cardiology diseases. As the current US population is fast aging, we examined whether this underrepresentation improved or worsened in the last 20 years in the most influential studies published between 1996 and 2015.

The main finding is that the women and older adults continue to be underrepresented in cardiology trials. Overall, the mean age was 63 years and the percentage of women was 29%. For coronary heart disease, women comprise 54% of the US population in need of treatment, yet are only 27% of the trial population. For heart failure, the median age of older adults in the US population is 70 years whereas it is only 64 years in the trial population.

Our results indicate that the gap has very slowly narrowed in the last 2 decades. However, based on current trends, reaching proportionate enrollment would require between 3 and 9 decades. This persistent lack of representation has significant impacts on the ability of clinicians to provide evidenced based care for these segments of the population. Physicians and other health care professionals are forced to extrapolate study results from younger and male-predominant populations. This is problematic since we know that older adults and women may react differently to medications and to interventions.  Continue reading

MedicalResearch.com: What is the background for this study? What are the main findings? 

Response: As a clinician in older adult care and as a health economist, I’ve been following the news and research studies on older patients unable to pay for their medications and consequently not getting the treatment they require. Our goal was to measure how spending on the medications Part D spends the most on, has been increasing over time and to figure out what prices patients are facing out-of-pocket to get these medications.

In 2015 US dollars, Medicare Part D spent on the ten highest spend medications increased from $21.5 billion in 2011 to $28.4 billion in 2015.  The number of patients that received one of the ten highest spend medications dropped from 12,913,003 in 2011 to 8,818,471— a 32% drop in that period.

A trend of spending more tax dollars on fewer patients already presents societal challenges, but more troubling is that older adults are spending much more of their own money out-of-pocket on these medications.  For patients without a federal low income subsidy, the average out-of-pocket cost share for one of the ten highest spend medications increased from $375 in 2011 to $1,366 in 2015.  This represented a 264% increase and an average 66% increase per year.  For patients receiving the low income subsidy, the average out-of-pocket cost share grew from $29 in 2011 to $44 in 2015 an increase of 51% and an average increase of 12.7% per year.  This may not sound like much, but for those living close to the federal poverty level this can be the difference between foregoing necessities to afford your medications or choosing not to take your medications.   Continue reading

Brighton and Sussex Medical School, UK 

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Older people are more like to have more than one chronic condition (multi-morbidity), and as such as are more likely to be prescribed several medications (poly pharmacy) to treat those conditions. At the point of hospital discharge, older people are given different / new medications in addition to their old ones, and this puts them at higher risk of harm related to medicines. Our study led by  Brighton and Sussex Medical School (BSMS) and King’s College London involved five hospitals and 1,280 patients (average age 82 years) in South England. Senior pharmacists interviewed patients and carers, reviewed GP records and analysed hospital readmission to determine medication-related harm.

The study found that more than one in three patients (37%) experienced harm from their medicines within two months of hospital discharge, and that this was potentially preventable in half of the cases. Medication-related harm was most commonly found to occur from the toxicity of the medicine itself and in a quarter of cases from poor adherence.  The medicines found to pose the highest risk were opiates, antibiotics and benzodiazepines. Patients suffered a range of side effects including serious kidney injury, psychological disturbance, irregular heart rhythms, confusion, dizziness, falls, diarrhoea, constipation and bleeding.

Rate of End-of-Life Medicare Spending Falls

William B Weeks, MD, PhD, MBA The Dartmouth Institute

Dr. Weeks

William B Weeks, MD, PhD, MBA

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: The background for the study is that a common narrative is that end-of-life healthcare costs are driving overall healthcare cost growth.  Growth in end-of-life care has been shown, in research studies through the mid 2000’s, to be attributable to increasing intensity of care at the end-of-life (i.e., more hospitalizations and more use of ICUs).

The main findings of our study are that indeed there have been substantial increases in per-capita end-of-life care costs within the Medicare fee-for-service population between 2004-2009, but those per-capita costs dropped pretty substantially between 2009-2014.  Further, the drop in per-capita costs attributable to Medicare patients who died (and were, therefore, at the end-of-life) accounts for much of the mitigation in cost growth that has been found since 2009 in the overall Medicare fee-for-service population.

How To Prevent the Elderly From Falling?

MedicalResearch.com Interview with:

Dr. Alex Krist

Dr. Krist

Dr. Alex Krist, M.D., M.P.H.

Dr. Krist is is a professor of family medicine and population health at Virginia Commonwealth University and active clinician and teacher at the Fairfax Family Practice residency.

What is the background for these recommendation statements? What are the main findings?

Response: Falls are the leading cause of injuries in adults age 65 and older and can lead to serious disability and even death. Bone fractures—which may result from a fall—can also cause serious disability and death in older adults.

The U.S. Preventive Services Task Force looked into the most recent evidence on the best ways to prevent falls and fractures in older adults. We found that clinicians should recommend exercise or physical therapy to help prevent falls by older adults who live at home and are at higher risk for falling.

Additionally, we concluded that taking a low dose of vitamin D and calcium does not help prevent fractures due to osteoporosis, but we don’t know if taking a higher dose is effective or not, so we are calling for more research.

Boston  MA  02131-1097

MedicalResearch.com: What is the background for this study?

Response: Previous studies have shown that higher milk intake is associated with higher bone mineral density. In one of our previous studies, we reported that higher dairy food intake was protective against bone loss especially among older adults who used vitamin D supplements. Older adults are at high risk of vitamin D deficiency because recommended intakes are difficult to achieve without fortified foods (such as dairy) or supplements. Vitamin D stimulates calcium absorption, which is beneficial for building bones. However, it is unclear if the effect of vitamin D on calcium absorption is substantial enough to translate into beneficial effects on bone.

Therefore, the current study determined the association of dairy food intake with bone health. We further examined whether these associations would be modified by vitamin D status.

MedicalResearch.com: What is the background for this study?

Response: The estimates in this study provide a more robust indicator of the economic impact falls have on the U.S. economy.  Previous studies focused on Medicare spending. This study includes Medicare, Medicaid and out-of-pocket spending.

MedicalResearch.com: What are the main findings? 

Response: Our study found that older adult (65 years and over) falls impose a large economic burden on the U.S. healthcare system. In 2015, with a total medical cost $50 billion for non-fatal and fatal falls.  About three-quarters of the total cost was paid by government-funded programs.  Medicare paid nearly $29 billion for non-fatal falls, Medicaid $8.7 billion, and $12 billion was paid for by Private/Out-of-pocket expenses.  For fatal falls, $754 million was spent in 2015.

Fellow, Department of Medicine
Weill Cornell Medical College – New York Presbyterian Hospital

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Heart Failure currently affects 5.8 million people in the United States and is becoming increasingly common as the population ages. Because it has no cure and tends to get progressively worse, physicians recommend that patients control their symptoms by taking multiple medications, maintain a diet low in salt, monitor their weight and blood pressure, and watch for changes in their symptoms.

At the most basic level, in order to understand and follow these instructions, heart failure patients must be able to hear them.  Hearing loss, however, had not been studied in heart failure.  There are a lot of chronic diseases in which hearing loss is more common than in the general population, including coronary heart disease, hypertension, and diabetes. And many adults with heart failure also have these conditions. So, we thought it would be important to understand if hearing loss was prevalent among adults with heart failure, especially since so much of heart failure management revolves around effective communication between patients and their healthcare providers.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: As part of a larger study (MODEM – modelling outcome and cost impacts of interventions for dementia) we have developed a microsimulation model called PACSim which forecasts the number of older people aged 65 years and over along with their health and lifestyle factors as they age over the next 20 years. Crucially these are the first projections that include the health and lifestyle profiles of younger people as they age into to older population, rather than just assuming they have the same health profiles as existing young-old.

Other studies have already reported that the proportion of older people with multimorbidity (two or more concurrent diseases) has increased. Our study shows that not only will this continue but that the largest increase over the next 20 years will be for complex multimorbidity (four or more diseases). Much of the gain in life expectancy over the next 20 year for a 65 year old will be years spent with complex multimorbidity. And more importantly the future cohorts of young-old entering the older population will have successively more multimorbidity. Continue reading

Good Relationship With Grandparents Mitigates Feelings Of Ageism

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Ageism—stereotypes that lead to prejudice and discrimination against older people— occurs frequently in young adults and can even be seen in children as young as 3.

Ageism has deleterious consequences on older people in our aging Western societies. However, the factors influencing this phenomenon in the young are not well known.

To answer this question, we have asked 1151 Belgian children and adolescents to provide their views of the elderly, using especially designed questionnaires and open questions. We found four main influences on their views of the elderly: gender and age of the child, quality of contact with grandparents, and grandparents’ health. Girls had slightly more positive views than boys. Ageist stereotypes fluctuated with age, with 7- to 9-year-olds expressing the most prejudice and 10- to 12-year-olds expressing the least. This finding mirrors other forms of discrimination (e.g., those related to ethnicity or gender) and is in line with cognitive-developmental theories. For example, acquiring perspective-taking skills around age 10 reduces previous stereotypes. With regard to ageism, prejudice seemed to reappear when the participants in this study reached their teen years: 13- to 16-year-olds had higher levels of ageism compared with younger children. Moreover, youths who described their contact with grandparents as good or very good had more favorable feelings toward the elderly than those who described the contact less positively.

Finally, children and adolescents with grandparents in poor health were more likely to hold ageist views than youths with grandparents in better health.

MedicalResearch.com: What is the background for this study?

Response: Micronutrients, which include vitamins, minerals (e.g. calcium) and trace elements (e.g. iron), are essential nutrients that are required in minute amounts by the organism for proper growth and good health. Results from the last German National Nutrition Survey (NVS II)* uncovered a high prevalence of insufficient dietary intake of micronutrients in older adults aged 65 years and over in Germany. By means of blood analyses, our study has confirmed these critical results. This is a highly relevant issue, particularly in light of our growing aging population and the high societal relevance of successful healthy aging.

MedicalResearch.com: What is the background for this study? 

Response: The mapping of the Human Genome 14 years ago ushered in a new era of precision medicine. Many people are familiar with advances in oncology using precision medicine, but recently, new developments in precision medicine in cardiology have allowed us to develop a tool to differentiate patients likely to have obstructive coronary artery (CAD) from those who have non-cardiac causes of their symptoms.

Diagnosing CAD in the elderly is challenging. Aging individuals often present with atypical symptoms of CAD which can complicate the evaluation process. The typical diagnostic pathway for possible CAD often starts with less invasive testing and progresses to invasive testing, especially in older patients. Invasive procedures pose greater risk in the elderly population than they do in younger patients because of the higher risk of side effects, including bleeding, vascular complications and kidney injury.

Elderly adults evaluated for CAD have a higher pretest probability of CAD and are also at higher risk of experiencing procedure-related complications during their evaluation.[i],[ii] It is also important to note that elderly patients are often underrepresented in clinical trials and other types of comparative effectiveness research.[iii],[iv] For example, the 2013 American College of Cardiology/American Heart Association Atherosclerotic Cardiovascular Disease Risk Algorithm is only formally approved to be used in individuals up to the age of 75, despite the fact that individuals exceeding this threshold in age experience higher rates of adverse cardiovascular events.[v]

All of this means that the elderly population may have the most to gain from timely and accurate determination of their currently likelihood of obstructive CAD.
This precision medicine tool, the age, sex and gene expression score (ASGES), and its clinical utility in the elderly population is the focus of this study. It was based on patient data from the PRESET Registry, a prospective, multicenter, observational study enrolling stable, symptomatic outpatients from 21 U.S. primary care practices from August 2012 to August 2014.

Response: Elderly represent the fastest growing segment of incident dialysis patients in Unites States. The annual mortality in end stage renal disease (ESRD) patients is very high ~ 20%.

Since most of the deaths occur in the first year of dialysis, it is possible that health conditions present prior to initiation of dialysis may impact long-term outcomes. In this study, we determined the impact of poor functional status at the time of dialysis initiation and pre-dialysis health status on type of dialysis modality, type of hemodialysis access and one-year mortality in elderly dialysis patients. We evaluated 49,645 adult incident dialysis patients (1/1/2008 to 12/31/2008) from the United Data Renal Data System (USRDS) with linked Medicare data for at least 2 years prior to dialysis initiation. Mean age of our study population was 72 years. At dialysis initiation, 18.7% reported poor functional status, 88.9% has pre-dialysis hospitalization, and 27.8% did not receive pre-dialysis nephrology care. Patients with poor functional status had higher odds of being initiated on hemodialysis than peritoneal dialysis, lower odds of using arteriovenous access as compared to central venous catheter for dialysis and higher risk of one-year mortality.

Focusing on Physical Activity Can Help Avoid Unnecessary Later Life Social Care Expenses

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: There are vast differences between older people in their abilities and their number of medical conditions. Many people confuse ageing with loss of fitness. Ageing has specific effects (reduction in hearing and skin elasticity for example) but the loss of fitness is not inevitable. Genetics contributes only 20% to diseases. There is abundant evidence that adults who take up physical activity improve their fitness up to the level of someone a decade younger, with improvements in ‘up and go’ times. Physical activity can reduce the severity of most conditions, such as heart disease or the risk of onset or recurrence of many cancers. Inactivity is one of the top four risk factors for most long-term conditions. There is a dose-effect curve. Dementia, disability and frailty can be prevented, reduced or delayed.

The need for social care is based on an individual’s abilities; for example, being unable to get to the toilet in time may increase the need for care from twice daily care givers to needing residential care or live-in care, which increases costs five-fold.

Hospitals contribute to people reducing their mobility, with the ‘deconditioning syndrome’ of bed rest, with 60% of in-patients reducing their mobility.

The total cost of social care in the UK is up to £100 billion, so even modest changes would reduce the cost of social care by several billion pounds a year.
