Geriatric Dermatology-A Framework for Caring for Older Patients With Skin Disease

Antihistamine safety in older adult dermatologic patients

Twenty percent of Americans will be older than 65 years by 2030, and without a dedicated geriatrics curriculum in many residency trainings programs, dermatologists may be less familiar with age-associated adverse effects of common dermatologic medications. Herein, we provide a practical guide and clinical safety pearls for the use of antihistamines in older adults. This Review aims to address the risks of antihistamines, anticholinergic burden and polypharmacy, pertinent preexisting medical conditions, and safe alternatives for aging adult patients.

Pressure Injury Prevention Considerations for Older Adults

There are well-documented physiologic changes that occur in the human body during the aging process, such as decreased body fat, decreased muscle mass, cellular senescence, changes in skin pH, decreased metabolism, decreased immune function, vascular changes, altered tissue perfusion, nutritional status changes, and poor hydration. These changes affect skin integrity and wound healing, and raise the risk of pressure-related skin injury. This article discusses aging as a risk factor for pressure injury (PrI). Topics include evidence for advancing age as a significant PrI risk factor, identifying pathophysiologic changes/mechanisms of aging, and specific PrI preventive interventions to consider in older adults.

Palliative care in dermatology: A clinical primer, review of the literature, and needs assessment

Palliative care has been shown to improve quality of life, symptoms, and caregiver burden for a range of life-limiting diseases. Palliative care use among patients with severe dermatologic disease remains relatively unexplored, but the limited available data suggest significant unmet care needs and low rates of palliative care use. This review summarizes current palliative care patterns in dermatology, identifying areas for improvement and future investigation.

Frailty screening in dermato-oncology practice: a modified Delphi study and a systematic review of the literature

Background

Appropriate management and prevention of both under‐ and overtreatment in older skin cancer patients can be challenging. It could be helpful to incorporate frailty screening in dermato‐oncology care, since frailty is associated with adverse health outcomes.

Objectives

This study aimed to identify and prioritize the requirements a frailty screening tool (FST) should fulfil in dermato‐oncology practice and to select the best existing FST(s) for this purpose.

Methods

A modified two‐round Delphi procedure was performed among 50 Italian and Dutch specialists and patients to review and prioritize a list of potential FST requirements, using a 5‐point Likert scale. Consensus was defined as a mean score of ≥4.0. A systematic literature search was performed to identify existing multidomain FSTs, which were then assessed on the requirements resulting from the modified Delphi procedure.

Results

Consensus was achieved on evaluation of comorbidities (4.3 ± 0.7), polypharmacy (4.0 ± 0.9) and cognition (4.1 ± 0.8). The FST should have appropriate measurement properties (4.0 ± 1.0), be quickly executed (4.2 ± 0.7), clinically relevant (4.3 ± 0.7), and both easily understandable (4.1 ± 1.2) and interpretable (4.3 ± 0.7). Of the 26 identified FSTs, four evaluated the content‐related domains: the Geriatric‐8 (G8), the modified Geriatric‐8 (mG8), the Groningen Frailty Indicator (GFI) and the Senior Adult Oncology Program 2 (SAOP2) screening tool. Of these, the G8 was the most extensively studied FST, with the best psychometric properties and execution within 5 min.

Conclusions

The G8 appears the most suitable FST for assessing frailty in older adults with skin cancer, although clinical studies assessing its use in a dermato‐oncology population are needed to further assess whether or not frailty in this particular patient group is associated with relevant outcomes (e.g. complications and mortality), as seen in previous studies in other medical fields.

A multiyear cross-sectional study of U.S. national prescribing patterns of first-generation sedating antihistamines in older adults with skin disease

BACKGROUND

First-generation antihistamines (FGAs) are classified as 'potentially inappropriate' for use in older patients (patients aged ≥ 65 years). However, the prevalence of and factors associated with FGA prescription have not been studied.

OBJECTIVES

To examine FGA prescription rates for older patients who visited dermatology offices, and compare them to those for younger patients (patients aged 18-65 years) who visited dermatology offices and those for older patients who visited primary-care physicians (PCPs).

METHODS

This was a multiyear cross-sectional observational study using data from the U.S. National Ambulatory Medical Care Survey (2006-2015). Visits by patients aged 18 years or older were included in the study; the data comprised 15 243 dermatology office visits and 66 036 PCP office visits. The main outcome was FGA prescription. Other variables included physician specialty (dermatologist or PCP), patient's age, diagnosis of dermatological conditions and reason for visit.

RESULTS

For dermatology visits, the overall FGA prescription rate for older patients was similar to that for younger patients (1·5% vs. 1·2%; P = 0·19), even when the diagnosis was dermatitis or pruritus (3·7% vs. 4·8%; P = 0·21) or when itch was a complaint (7·6% vs. 6·7%; P = 0·64). However, the rate of FGA prescription for dermatology visits was lower than that for PCP visits, in analyses matched for patient and visit characteristics (3·9% vs. 7·4%; P = 0·02).

CONCLUSIONS

Our findings suggest that FGAs are overprescribed to older patients but that dermatologists are less likely to prescribe FGAs than PCPs. What's already known about this topic? First-generation antihistamines (FGAs) have been shown to pose substantial risks to older adults, including cognitive impairment, falls, confusion, dry mouth and constipation. Therefore, FGAs have been classified as 'potentially inappropriate' for use in older patients by the American Geriatrics Society. It has also been shown that dermatologists do not always take patient characteristics (e.g. age or life expectancy) into account when deciding on a treatment, instead following a 'one-size-fits-all' approach. What does this study add? FGAs are often prescribed during dermatology visits, and prescription rates do not differ between older and younger patients. There were no significant differences in prescription rates when comparing younger and older adults with the same diagnosis or symptom (e.g. dermatitis, pruritus or itch). FGAs are prescribed at higher rates in primary-care offices than in dermatology offices.

Pigmentation Disorders in the Elderly

Aging skin is subject to morphological change due to both intrinsic (skin tone, genetics, endogenous hormones) and extrinsic (chronic sun exposure, medications, exogenous pigments) factors. The broad spectrum of transformation includes both hypo- and hyperpigmentation. Although cutaneous pigmentary disorders are common in younger individuals, certain disorders are more prevalent in the geriatric population. This article reviews the epidemiology, pathophysiology, clinical appearance, treatment, and prognosis of pigmentary lesions that are predominant in the elderly.
