Letter to the Editor, September 2009

Dear Editor,

First, I wish to congratulate you and your team for a superb magazine. I much enjoy the reading and find the articles of high quality.

I am surprised, however, by seeing in this Canadian publication frequent use of non-SI units. For example, in a recent publication (July 2009), the serum-ascites albumin gradient is reported in g/dl, while I would expect the units to be in g/L; the serum creatinine is reported in mg/dl, while in Canada we are familiar with µmol/L. As you know, the conversion from one unit to the other is not always an easy calculation. I recommend universal use of SI units in documents, for easier knowledge translation and adaptation to clinical practice. If needed, the other unit values could be put in parentheses.

Thanks again for the great publication.

Editor’s Reply

Dear Dr. Léger-Nolet,

Thank you for your kind words about our journal. We agree that SI units are the preferred unit of measurement, and we will do our best to ensure that they are the standard in our future issues.

Letter to the Editor, June 2009

To the Editor:

I must congratulate Glaser and Rolita on covering an important and challenging area of medication practice in the March 2009 issue of Geriatrics & Aging. However, I do have a couple of questions/comments:

  1. The authors mentioned simethicone within the class of antacid medications, but my understanding is that its mechanism of action is to alter the surface tension of gas bubbles produced during the digestion of food. It is safe in older adults but has no impact on gastric acid or heartburn per se.
  2. Could you please clarify which drug interactions are similar between proton pump inhibitors and H2-blockers? My understanding was that the latter, particularly older drugs such as cimetidine, had significantly more drug interactions than PPIs.
  3. I understood loperamide had anticholinergic properties and might not be very safe in patients with moderate dementia.
  4. Among laxatives, lactulose is an osmotic laxative but is it not safe in renal failure? Plus a previous article in Geriatrics & Aging suggested that docusate sodium is not very effective in the treatment of constipation.

Please comment.

Sincerely,
A Physician*

The authors respond:

In response to the query on Educating the Older Adult in Over-the-Counter Medication Use, simethicone is a surfactant and may modulate gas handling. Simethicone is taken to reduce gas, as it acts in the stomach and intestines to change the surface tension of gas bubbles. Although it is generally considered to be of no specific value in functional dyspepsia, recent trials have shown that it helps with the overall improvements of functional dyspepsia. When compared to cisapride, simethicone was superior in the treatment of patients with functional dyspepsia.1

Proton pump inhibitors are generally well tolerated with few side effects. However, they have the same drug interactions as H2RAs but are less reported. These are listed under H2RAs in Table 4 of Educating the Older Adult in Over-the-Counter Medication Use, and include fluoxetine, chemotherapy drugs, theophylline, warfarin, carbamazepine, phenytoin, isoniazid, ciprofloxacin, ketoconazole, and valproic acid. Cimetidine has been associated with acute liver disease more frequently than other H2RAs.2 The most serious interaction is the risk of parkinsonism with a combination of fluoxetine and cimetidine.3

The nonopioid actions of loperamide contributes to the reduction of acetylcholine release from human cholinergic nerves.4 Older adults are at greater risk for increased cholinergic load when multiple drugs with anticholinergic activity are used.5 Taking other medications with anticholinergic properties or having an underlying cognitive dysfunction, such as moderate dementia, makes an older adult particularly susceptible to these side effects.

Docusate sodium is a surfactant laxative. Controlled clinical trials of docusate sodium are limited. The mechanism of action is to allow penetration of water and fat into feces. It is generally slow to work6 yet is generally safe and a good first line of therapy, especially for patients who suffer from hard stools as the underlying cause of their constipation. The inquirer is right in pointing out that docusate sodium is not the most effective agent for the treatment of constipation, but it is safe and works well with hard stools. Psyllium has been shown to be superior to docusate sodium in the treatment of chronic constipation, as it results in significant improvement in evacuation completeness.7 Polyethylene glycol is also relatively safe to use and is now available over the counter as Miralax. Lactulose is an established therapy for hepatic encephalopathy and shows effectiveness for constipation. Lactulose can result in electrolyte abnormalities in high doses and more so in patients of renal failure so this should be closely monitored by a physician if the patient takes it regularly.

What's in a Name? A Call to Arms!

It is well known that older adults consume many more prescription drugs than would be expected from their proportion of the population. In Ontario, where about 13% of the population is over age 65, about 40% of prescription drugs are consumed by that group.

I therefore find it strange when some media agencies advise us that pharmaceutical companies they represent do not advertise in journals such as ours because they do not target physicians who provide geriatric care. They cite the “negative” connotations of the word geriatrics in the title as a justification for not supporting the journal with advertising. I have always found this to be counterintuitive: advertising should be directed at those doctors who actually see and prescribe for older adults. Advertising is an important source of revenue that allows our journal to keep publishing the timely information that physicians need, but it’s also a tool for introducing physicians to medications that may help their patients.We value the support provided by the progressive companies and agencies that regularly advertise with Geriatrics & Aging.

What can we do to eliminate the stigma that not only prevents advertisers from investing in journals that serve health professionals who care for aging adults, but also undermines the appeal of geriatric medicine in our medical schools and the agencies and institutions we must work with to improve elder care? The comments you see in this issue are a few responses we were able to include, sent in by our partners in the Canadian Geriatrics Society and Canadian Academy of Geriatric Psychiatrists, but we’d like to hear from you, our eleven thousand (!) readers, who are also working on the front lines with many aging adults. I strongly encourage you to add your thoughts to our online forum at www.geriatricsandaging.ca/links/calltoarms/

One final note: as a founding member of the Canadian Geriatrics Society, I’m inviting all our readers to attend the CGS 2009 Annual General Meeting, a great opportunity to talk with peers, learn the latest research in geriatric care, and develop new skills for offering the best possible care for older adults. As the population ages, these skills will become all the more valuable: why not join CGS now and add your name to the list of professionals working to improve the care of aging Canadians?

Peptic Ulcer Disease in Older Adults - letter


To the Editor:

Could the authors of the February 2007 article “Peptic Ulcer Disease in Older Adults” (Geriatrics Aging 2007;vol. 10, no. 2:77-83) please comment in a bit more detail on the evidence supporting the statement that “it would be prudent not only to switch to a COX-2 inhibitor but also to add a PPI” (p. 82, section on NSAIDs, last sentence).

Toronto Physician

Drs. Constantine A. Soulellis and Carlo A. Fallone respond:

To our knowledge, the issue of concurrent usage of COX-2 inhibitors and proton pump inhibitors (PPIs) has been explored in the literature only once before;1,2 this was a negative study that failed to demonstrate superiority of COX-2 inhibitors/PPIs over nonselective NSAIDs/PPIs in high-risk GI patients. However, we would like to disclose that we are privy to the results of a large retrospective cohort study conducted at McGill University and the University of Montreal that included over two million registered prescriptions for COX-2 inhibitors, nonselective NSAIDS, PPIs, and every combination thereof. The findings, to be published in an upcoming issue of Arthritis and Rheumatism (July 2007),3 demonstrate a clear reduction in the studied outcome (hospitalizations from perforated or bleeding ulcers) for COX-2 inhibitors plus PPIs compared to COX-2 inhibitors alone for ages greater than 75. COX-2 inhibitors and PPIs were also found to be superior to nonselective NSAIDs and PPIs for the same measured outcomes.

I hope this explanation is satisfactory for your readers. Again, thank you kindly for affording us the opportunity to contribute to Geriatrics & Aging.

Regards,
C. A. Fallone and C. A. Soulellis

Visual Hallucinations among Older Adults: The Charles Bonnet Syndrome

Nages Nagaratnam, MD, FRCP, FRACP, FRCPA, FACC, Consultant Physician in Geriatric Medicine, Department of Geriatric Medicine, Blacktown-Mt-Druitt Health, Blacktown, NSW, AUS.

A 73-year-old woman was seen in hospital troubled with visual hallucinations for over a year. They had increased in both frequency and intensity in the past few months, necessitating hospitalization. To her annoyance, the visual images took the form of people watching her through the glass windows. She less frequently saw animals. The hallucinations occurred both during the day and night but were worse as evening approached.

New Horizons for Geriatrics & Aging

I am always excited when a new edition of Geriatrics & Aging is coming to press, but this month I am particularly enthusiastic. Geriatrics & Aging now has a formal agreement with the Canadian Geriatrics Society (CGS) to publish its journal, the Journal of the Canadian Geriatrics Society. From the perspective of the team at G&A, this is a wonderful opportunity to further our educational mandate by having a journal that will appeal to specialists in the field. The possibilities of synergy, particularly in on-line educational programs, are unlimited. As a founding member of CGS, and having served multiple roles including executive member, secretary-treasurer, president, annual meeting program chair, and currently as chair of the education committee, I feel this will be a wonderful opportunity for the Society. Their research-oriented journal will benefit enormously from the committed and experienced publishing and editorial team at G&A, and their relationship with G&A will help them better fulfill their constitution’s mandate to improve care of older adults in Canada by providing continuing education. This new alignment has the potential to help doctors in Canada provide better care to their older patients.

My enthusiasm also extends to the focus of this issue. Our opening articles fall under the theme of endocrinology and metabolic issues such as obesity. When I started my practice in geriatrics, I thought that nutrition was one of those “soft” areas of endocrinology and metabolism, not of great interest to doctors. Modern medicine no longer believes that, and it seems that most complex geriatric cases have major nutritional issues. These issues span the entire spectrum of nutrition, from affording food, being able to shop and prepare food, the taste and textures of food, the amount eaten, the ability to chew, and the ability to swallow, just to name the most obvious.

The series begins with our CME article, concerning the “Diagnosis and Management of Hyperthyroidism in Older Adults” by Drs. Shakaib U. Rehman, Jan Basile, and Florence N. Hutchison. Geriatricians, internists, and family physicians often see older adults who have lost weight unintentionally. Karen L. Smith and Drs. Carol Greenwood, Helene Payette, and Shabbir M.H. Alibhai, who is G&A’s Senior Editor, address this common problem in their article “Unintentional Weight Loss among Older Adults: Diagnosis, Epidemiology, and Importance.” Even though weight loss is a common problem in an individual doctor’s office, from a public health perspective, obesity is even more dire. The article “Obesity among Older Adults” by Drs. Dennis Villareal and Krupa Shah addresses this important issue.

As well, we have numerous articles on other topics pertaining to the care of older adults. Our Cardiovascular column is contributed by Dr. Jagdish Butany, Gursharan S. Soor, Moyukh Chakrabarti, Iva Vukin, and Shaun W. Leong, who offer the first of a two-part article on “Prosthetic Heart Valves: Identification and Potential Complications.” At one time, most valvular lesions were caused by rheumatic fever and congenital abnormalities; today, degenerative age-related problems are a frequent cause of valvular disease. For our Dementia theme, Dr. Sudeep Gill provides an “Update on Delirium.” There has recently been growing attention to prevention and treatment of this life-threatening syndrome among older adults. Our column on Ear, Nose, & Throat Disorders is authored by Dr. Clodagh Ryan, who provides us with an approach to “Chronic Cough in Older Adults.” Finally, Dr. Mary Beth Jennings and Frances Richert write about “Hearing Rehabilitation for Older Adults: An Update on Hearing Aids, Hearing Assistive Technologies, and Rehabilitation Services” for our Technology in Medicine column, which will be particularly helpful to me in my dealings with my mother, who has two hearing aids!

Lost in Transition: Medication Errors at the Time of Hospital Admission, Transfer, and Discharge

Edward Etchells,MD, MSc, FRCP, Division of General Internal Medicine and Patient Safety Service, Sunnybrook & Women’s College Health Sciences Centre; Associate Professor, Department of Medicine, University of Toronto,Toronto, ON.
Tasnim Vira, BScPhm, Medical Student, Faculty of Medicine,University of Toronto, Toronto, ON.
Vincent C.Tam,MD, BSc(Hon), Internal Medicine Resident, Department of Medicine, McMaster University, Hamilton, ON; Thunder Bay, ON.

Medication errors at the time of acute care transition (admission, transfer, and discharge) are common. Health care providers can reduce these errors by obtaining an insightful medication history, documenting medication changes in medication orders and on discharge prescriptions, and promoting close teamwork among physicians, nurses, and pharmacists. The patient and family can also play an active role in reducing these errors. Medication reconciliation is a method for identifying and rectifying medication errors at transition. Reconciliation is a safe medication practice promoted by the Safer Healthcare Now campaign and is an accreditation requirement by the Canadian Council on Health Services Accreditation (CCHSA). Debates about the need for better studies examining the impact of reconciliation are ongoing.

The Clinician’s Role in the Treatment of Bathing Disability

Meera George, JD, Postgraduate Fellow, Houston Center for Quality of Care and Utilization Studies, Michael E. DeBakey VA Medical Center, Houston,TX, USA.
Aanand D. Naik,MD, Assistant Professor, Health Services Research and Geriatrics, Baylor College of Medicine; Houston Center for Quality of Care and Utilization Studies, Michael E. DeBakey VA Medical Center, Houston,TX, USA.

Many older adults have difficulty bathing.Those unable to bathe are more likely to need formal home care and to be admitted to long-term care than those who can bathe without help. Disability with bathing function is complex, involving multiple subtasks; inability to perform those subtasks has many attributable causes. Bathing disability can be remediated through timely diagnosis and prescription of appropriate assistive devices and adaptations to the home bathing environment. Clinicians have an important role in the diagnosis of bathing disability, and collaborative planning of bathing remediation with patients, caregivers, and allied health providers is key.
Keywords: activities of daily living, assessment, disability, assistive devices.

The Significance of Gender in Treating Aging Adults



This month’s issue of Geriatrics & Aging focusses on Gender and Health. Because there are more women than men among the aging population, geriatricians have often considered themselves by virtue of practical experience to be up-to-date on gender-based issues. As well, geriatrics was the first specialty or subspecialty certified by the Royal College to achieve gender parity between men and women.

Not only do women predominate in the older age groups, they may also survive longer with serious diseases and disability, frequently presenting challenging diagnostic and management issues. The investigators in the New England centenarian project have long observed that while a 100-year-old woman may be sick and/or disabled, a 100-year-old man who develops serious disability usually dies rapidly. Of course, men also have distinct age-related problems (prostatic disease being the obvious example). The particular example of the under-recognition of osteoporosis in older men reminds me of when I was an intern and told my staff physician, “I have never seen that disease.” He gently corrected me, saying, “Barry, you might have seen it, but just not recognized it!”

The first article in this issue’s Gender and Health series, “Benign Breast Disease in Older Women” by Drs. Nehmat Houssami and Michael Dixon, is also our featured CME article. The article “Living with Ovarian Cancer: Perspectives of Older Women” by Dr. Margaret Fitch approaches this difficult topic from the patient’s point of view. As a contrast to the old view that Women’s Health was primarily a concern for obstetricians/gynecologists, we have the article “Postmenopausal Health” by Drs. Lynne T. Shuster, Sharonne N. Hayes, Mary L. Marnach, and Virginia M. Miller, which takes a broader view of women’s health concerns. Currently, almost half of a woman’s life spans the postreproductive years, and there are many more health concerns for older women than younger ones.

We also have our usual collection of articles on other topics. Cholesterol levels are a topic of concern and Dr. Patrick Couture and Nancy Gilbert provide an update on “Significance and Treatment of Hypertriglyceridemia.” Our Arthritis column by Marie D. Westby and Dr. Linda Li addresses the role of physiotherapy in maintaining the physical well-being of older adults living with arthritis. This issue’s Drugs & Aging column, “Alcohol and Prescription Drug Interactions Among Aging Adults” by Drs. Kristine E. Pringle, Frank M. Ahern, and Debra A. Heller, presents a key yet all-too-often neglected issue: the prevalence of older adults combining medication with alcohol usage, the consequences of which may be severe. Bathing and hygiene are critical issues for frail older people, particularly those with cognitive impairment who may be resistant to care. This topic is addressed by Meera George and Dr. Aanand D. Naik in their article “The Clinician’s Role in the Treatment of Bathing Disability in Older Adults.”

All of us are concerned with patient safety, but few of us have devoted our careers to this topic the way Dr. Ed Etchells has. Dr. Etchells, Tasnim Vira, and Dr. Vincent Tam contribute the article on “Medication Errors.” Every year the spectre of an influenza outbreak frightens all of us who care for older people. This year is particularly concerning because of the recent (as of late September) report that this year’s vaccine delivery will be delayed. This important issue is addressed in the article “Influenza Prevention and Treatment” by Dr. Roger Thomas. Finally, the journal’s Editorial Director, Kristin Casady, reports on results of a recent study aimed at improving medication compliance with telephone counselling.

Compassionate Care in the ICU: Creating a Humane Environment

Jeffrey Farber, MD, Brookdale Department of Geriatrics and Adult Development Mount Sinai School of Medicine, New York, NY, USA.

An educational video entitled “Compassionate Care in the ICU,” funded by Ortho Biotech and produced by the Society of Critical Care Medicine, aims to improve end-of-life care for patients dying in the intensive care unit (ICU). It is a well-paced, well-filmed video that alternates between advice and opinions from experts in the field of critical care, and poignant, still, black-and-white and colour photographs of common scenes in the ICU. There are two distinct videos: a shorter version intended for professional use, and a second for families of patients being cared for in the ICU. While overlapping in core content, there are significant differences between the two.

The professional video begins with recognition by experts that good communication is both lacking and needed in the ICU. Common barriers to effective communication are discussed, such as deficiencies in the physical environment, physician-family misunderstandings and conflicts, and the paucity of formal staff training in communication skills. Specific examples, such as noise, bright light, and a busy and fast-paced environment are noted, but advice on how to deal with these impediments is lacking. While the video stresses the importance of listening, of “putting down your stethoscope” and “being with a dying patient,” it does not sufficiently address how to establish goals of care with a patient’s family. Indeed, the term “goals of care” is not introduced until the very end of the 25-minute video.

The professional video does a nice job of discussing the need to guide families through the transition from the aggressive, curative approach of a critically ill patient to the symptom-focussed, palliative care approach. It clearly highlights the importance of treating the patient-family unit and credits the physician’s role in providing good palliative care. A highlight of the video features an ICU physician clearly explaining the necessary skills involved in organizing and carrying out an effective family meeting, from preparation to finding a quiet setting, to having a focussed agenda and summarizing and establishing a clear follow-up plan for the family. This is followed by another expert’s recommendation to have physicians train to communicate via professional actors playing family member roles.

While the video makes a convincing argument for the need to better care for dying patients in the ICU, it unfortunately fails to touch upon common specific scenarios that would help its intended audience. Shifting from a curative to a palliative approach often occurs in stages over time. The best tool to help this transition along is a clear and frank discussion of the goals of care. When it becomes clear that the goal is comfort, then the plan of care needs to be reviewed and revised so that all interventions and therapies accord with this goal of care. It is common for clinicians and families to decide together for example that no further blood draws or diagnostic radiographic imaging be performed. Likewise, commonplace, almost standard, ICU monitoring such as telemetry, urinary catheters, and continuous intra-arterial blood pressure need to be reviewed and discontinued if not achieving the goals of care. Unfortunately, there is not one photo in the video of an ICU patient that is not connected to a telemetry monitor and various intravenous catheters.

Likewise, the option of having dying patients transferred out of the ICU to a more appropriate setting is not mentioned. As one clinician described in the video, ICU care is best considered a “therapeutic trial” of a clinical strategy. When this trial fails, then one valid option is to transfer the patient out of the ICU setting to an environment where the goals of care can be better achieved. The ICU is indeed a busy and fast-paced environment with an invasive and aggressive approach to curative care, and it is not feasible to expect the professionals working there to easily shift gears and embrace and excel in providing expert palliative care. While it is important for intensivists to acknowledge the importance of palliative care and good communication skills, it is also important to recognize that optimal end-of-life care more often and readily occurs outside of the ICU setting.

While the expert opinions and still photos are effective, what’s missing in this professional version of the video are the personal and the patient-family unit’s voice. There is no physician account of a specific memorable case, nor a deceased patient’s loved one discussing her experience with end-of-life care in the ICU. This stands in sharp contradistinction to the more touching and personal family version of the video.

In the family version of the video, similar issues such as good communication and the importance of effective symptom management are well-addressed. In addition, establishing goals of care through ongoing communication over time is much better emphasized. There is a wonderfully moving account by a critical care physician of a previously healthy patient who became quadriplegic and ventilator-dependent after a motor vehicle accident. He expertly describes the patient’s eventual transition to palliative care, removal of mechanical ventilatory support, and dying with his family present, drinking a glass of red wine, and being kept free from dyspnea with the appropriate administration of morphine. There is a similarly well-done piece discussing the importance of advanced care planning, specifically highlighting the need to designate a health care proxy and to discuss with the proxy what is an acceptable functional state and quality of life.

The family version does a much better job of clearly stating that there is always something we as professionals can do for patients, that withholding life support does not equal withholding care, and that technologies can be correctly described as death-prolonging as opposed to life-extending when used inappropriately. Families are encouraged to initiate conversations with critical care staff and are assured that dying does not have to be painful nor isolating. There is an effective scene of a critical care expert advising family members on how to achieve closure with a dying loved one. She specifically addresses forgiving the dying person, asking for forgiveness, saying, “I love you,” and then saying goodbye. Likewise, there is a powerful still black-and-white photograph of a patient in the ICU sitting up in a chair with a neck dressing covering what is likely a recently discontinued central venous catheter, shaking hands with a physician. This photo masterfully shows the potential of the ICU to be a place where a person can die a good death. Nearly all that is lacking in the professional version exists in the family version. I would advise critical care units to use both versions to help educate staff to improve care for dying patients and their loved ones.
