Ethical issues in geriatrics: a guide for clinicians

Influences on the duration and success of out-of-hospital resuscitation of geriatric patients over 80 years of age - a retrospective evaluation

BACKGROUND

Society is experiencing an increasing shift in the age distribution and accordingly, increased resuscitation rates of patients over 80 years and older. In 2022, more than 34% of people resuscitated in Germany were older than 80 years, although older age is considered a poor predictor for the outcome of cardiopulmonary resuscitation (CPR). Professional societies provide ethical recommendations on when resuscitation may be considered futile and should be terminated. However, the extent to which these recommendations are implemented is unclear.

METHODS

Retrospective evaluation of pre-hospital documentation of out-of-hospital resuscitations in patients ≥ 80 years of age in the period 01/01/2014-12/31/2022 in one German county combined with data of the German Resuscitation Registry. For statistical testing, the significance level was set at p < 0.05.

RESULTS

In total 578 cases were analyzed. Return of spontaneous circulation (ROSC): 26% (n = 148). Survival to discharge: 6.1% (n = 35). Median CPR duration: 17 min (10-28 min). The older the patients were, the worse the survival rate (p = 0.05) and the shorter the time to termination (p < 0.0001). No patient over 90 years of age was discharged alive. Resuscitation was also significantly shorter until termination with poorer ASA (American Society of Anesthesiologists) score (p < 0.001). Residents resuscitated significantly longer than specialists (p = 0.02). In surviving patients, there was a significant correlation between short CPR duration and good cerebral performance category (CPC) value: Median CPC1/2 = 5 min [3-10 min] vs. CPC 3/4 = 18 min [10-21 min]; p = 0.01.

INTERPRETATION

Old age and poor health status is associated with shorter CPR duration until termination and older age is associated with poorer prognosis in out-of-hospital cardiac arrest (OHCA) concerning the possibility of return of spontaneous circulation (ROSC) and survival. A short resuscitation time is associated with a better CPC value. Therefore, when resuscitating patients over 80 years of age, even greater care should be taken to ensure that reversible causes are quickly corrected in order to achieve a ROSC and a good neurological outcome. Alternatively, resuscitation should be terminated promptly, as good survival can no longer be guaranteed. Resuscitation lasting more than 20 min should be avoided in any case, in line with the termination of resuscitation (ToR) criteria.

Methodological and ethical challenges in designing and conducting research at the end of life: A systematic review of qualitative and textual evidence

AIM

This systematic review aims to identify methodological and ethical challenges in designing and conducting research at the end of life from the perspective of researchers and provide a set of recommendations.

BACKGROUND

Conducting research with patients and family carers facing end-of-life issues is ethically and methodologically complex.

DESIGN

A systematic review was conducted.

DATA SOURCES

Four databases (MEDLINE, EMBASE, CINAHL, PsycInfo) were searched from inception until the end of 2021 in February 2022.

REVIEW METHODS

The Preferred Reporting Items for Systematic Reviews was followed, and the JBI Approach to qualitative synthesis was used for analysis.

RESULTS

Seventeen of 1983 studies met inclusion criteria. Data were distilled to six main themes. These included (1) the need for flexibility at all stages of the research process; (2) careful attention to timing; (3) sensitivity in approach; (4) the importance of stakeholder collaboration; (5) the need for unique researcher skills; and (6) the need to deal with the issue of missing data.

CONCLUSION

The findings illuminate several considerations that can inform training programmes, ethical review processes and research designs when embarking on research in this field.

Prevalence and factors of discordance attitudes toward advance care planning between older patients and their family members in the primary medical and healthcare institution

Background

This study aimed at investigating the prevalence and factors of the discordant attitudes toward advance care planning (ACP) among older patients and their family members toward patients' engagement in ACP in the primary medical and healthcare institution.

Methods

In a cross-sectional study, a total of 117 older patients and 117 family members from Jinhua Fifth Hospital in China were enrolled. The questionnaire included sociodemographic characteristics, functional capacity assessment, and attitudes toward patients' engagement in ACP. Functional capacity assessment scales included the Modified Barthel Index (MBI), the Short-Form Mini-Nutritional Assessment (MNA-SF), the 15-item Geriatric Depression Scale (GDS-15), the Mini-Mental State Examination (MMSE), the Clinical Frailty Scale (CFS), and the SARC-F questionnaire.

Results

The discordance attitudes toward patients' engagement in ACP between patients and family members accounted for 41(35.0%). In the multivariate logistic analysis, factors associated with higher odds of discordance attitudes toward patients' engagement in ACP included greater age differences between patients and family members (OR = 1.043, 95% CI: 1.007-1.081), lower educational level for family members (OR = 3.373, 95% CI: 1.239-9.181), the patient's higher GDS-15 score (OR = 1.437, 95% CI: 1.185-1.742), and patient's higher MNA-SF score (OR = 1.754, 95% CI: 1.316-2.338).

Conclusion

Older patients and their family members had little ACP knowledge, and factors that influence discordance attitudes toward patients' engagement in ACP included the age gaps between patients and family members, family members' educational level, patients' depressive symptoms, and patients' nutritional status.

Perspective of geriatric patients on advance care planning in Denmark: a qualitative study

OBJECTIVE

Most previous studies on advance care planning (ACP) have focused on patients with specific diseases and only a few on frail ageing individuals. We therefore decided to examine the perspective of geriatric patients on ACP. Our research questions include if, when, with whom and with which content geriatric patients wish to have ACP conversations.

DESIGN

Participants were interviewed either in the hospital or in their own home. The interviewer followed a semistructured interview guide. Interviews were transcribed and analysed using the systemic text condensation method.

SETTING

Geriatric department in a regional hospital in a rural area in Region Zealand, Denmark.

PARTICIPANTS

We included 11 geriatric patients aged above 65 who had been referred for geriatric inpatient or outpatient assessment. Participants were clinically judged by experienced geriatricians to have sufficient physical and mental capacity to take part in an interview.

RESULTS

This study's main finding is that geriatric patients have varying preferences and feelings towards ACP. Some expressed concerns about ACP, especially regarding personal fear to talk about end-of-life (EOL) decisions, and whether a busy healthcare system has the resources to conduct ACP. Proper timing of ACP seemed unrelated to specific age but related to perception of health situation. The health professional involved should be well trained and a person the participant could trust. Most participants wanted family members to participate. Concerning content, participants mentioned quality of life, fear of losing their spouse, earlier experience with death, and practical concerns regarding funeral and will.

CONCLUSION

Among geriatric patients, feelings towards ACP are mixed. Even participants who were generally positive towards the concept uttered concerns about the circumstances when talking about EOL topics. Health professionals therefore should approach ACP discussions with caution. Further studies aiming to develop guidelines describing the proper way to introduce and perform ACP in this patient group are needed.

Ethical issues in geriatric cranial neurosurgery

The global demographic shift to an older population has led to the emergence of the new field of geriatric neurosurgery. Beyond the complexities of disease states and multimorbidity, advanced age brings with it intricate ethical issues pertaining to both the practice and provision of medical and surgical care. In this paper, the authors describe the central ethical themes seen across the spectrum of common neurosurgical conditions in the elderly and highlight the use of foundational ethical principles to help guide treatment decision-making.

Navigating the Minefield of QTc Interval-Prolonging Therapy in Nursing Facility Residents

BACKGROUND

The exponential increase in the number of medications associated with clinically important prolongation of the heart rate-corrected QT interval (QTc) places older adults at increased risk of arrhythmias including life-threatening torsade de pointes (TdP) and sudden death. Risk factors, other than age older than 65 years and female sex, include multiple concurrent drugs that prolong QTc and a variety of underlying predisposing conditions. Although electronic medical records and pharmacy dispensing systems can alert clinicians to the risk of QTc-prolonging therapy, more than 95% of safety alerts are overridden, and many systems have deactivated QTc drug interaction alerts. The clinical consequences, magnitude of the effect, mitigation strategies, and recommended monitoring are not well defined for nursing facility (NF) residents.

DESIGN

Narrative review.

SETTING

NFs in the United States.

PARTICIPANTS

NF residents.

RESULTS

Medications known to prolong QTc include selected anti-infectives, antidepressants, urinary anticholinergics, antipsychotics, and cholinesterase inhibitors (eg, donepezil), used commonly in NFs. Drug-drug interactions are a risk when adding a medication that exaggerates the effect or inhibits the metabolism of a QTc-prolonging medication. The vast majority of patients in whom TdP is induced by noncardiac drugs have risk factors that are easily identifiable.

CONCLUSIONS

Recommendations are provided to improve standardization and use of drug interaction alerts, evaluate the risk of QTc-prolonging drugs in older adults receiving generally lower doses, validate a QTc risk score addressing complex multimorbidity, garner evidence to guide clinical decision making, avail NFs of access to electrocardiograms and interpretive recommendations, and develop standards of practice for hosting risk discussions with residents and their families.

A Medical Incapacity Hold Policy Reduces Inappropriate Use of Involuntary Psychiatric Holds While Protecting Patients From Harm

BACKGROUND

The use of involuntary psychiatric holds (IPH) to detain patients who lack the capacity to make health care decisions due to nonpsychiatric conditions is common. While this practice prevents patient harm, it also deprives civil liberties, risks liability for false imprisonment, and may hinder disposition. Medical incapacity hold (MIH) policies, which establish institutional criteria and processes for detaining patients who lack capacity but do not meet criteria for an IPH, provide a potential solution.

METHODS

A retrospective chart review was conducted on adult medical/surgical inpatients placed on an IPH or MIH over the 1-year periods before and after implementation of a MIH policy at an academic medical center. The primary outcome was frequency of IPH utilization in patients who did not qualify for an IPH as determined by 2 independent physician reviewers. A Cohen's kappa was calculated to determine inter-rater reliability. Differences in patient demographics and outcomes were compared using a Student's t-test, Wilcoxon rank-sum test, and Pearson chi-square test (α = 0.05).

RESULTS

The Cohen's kappa was 0.72 indicating substantial agreement. Seventy MIHs were placed after implementation (mean duration 4.3 days). Before MIH implementation, 17.6% of IPHs were placed on non-qualifying patients, which decreased to 3.9% following MIH implementation (p < 0.01). The average length of stay for patients on an IPH or MIH did not change following MIH implementation. No instances of patient elopement, grievances, or litigation were found.

CONCLUSION

MIH policies benefit both patients lacking capacity and the health care systems seeking to protect them while avoiding inappropriate use of IPHs.

Relational autonomy in action: Rethinking dementia and sexuality in care facilities

Background:

Caregivers and administrators in long-term facilities have fragile moral work in caring for residents with dementia. Residents are susceptible to barriers and vulnerabilities associated with the most intimate aspects of their lives, including how they express themselves sexually. The conditions for sexual agency are directly affected by caregivers’ perceptions and attitudes, as well as facility policies.

Objective:

This article aims to clarify how to approach capacity determinations as it relates to sexual activity, propose how to theorize about patient autonomy in this context, and suggest some considerations for finding an ethically responsible and practically feasible way to respect the sexual rights of this population.

Research Design:

The focus is on residents with early to moderate dementia in states of daily dependency on professional caregivers. The article critically examines existing empirical research on sexuality among persons with dementia, caregivers’ attitudes, and institutional roadblocks to enabling residents’ sexuality. A relational lens and insights from disability studies are used in the philosophical analysis.

Participants and Research Context:

No research participants were part of this analysis.

Ethical Considerations:

This article offers a conceptual analysis and normative framework only.

Findings:

The analysis highlights the delicate balance that capacity assessments for sexual activity have to strike; while caregivers should protect those who cannot give adequate consent, the denial of sexuality among residents can cause deep, long-ranging harms. Sexual agency features into an ongoing sense of self for many individuals with dementia, and the imposition of inappropriate standards and expectations for sexual autonomy can lead to unwarranted obstacles to sexual activity.

Discussion:

Recommendations include developing clear and inclusive institutional policies and practices of care, providing education for caregivers on how to discuss and document residents’ sexual preferences over time, and taking advantage of ethics consultation services.

Conclusion:

This analysis establishes the need for more research and discussion on this sensitive topic. Future research should investigate the specific responsibilities of caregivers in furthering the sexual interests of residents, how exactly to modify existing capacity instruments, and how best to support historically marginalized patients in their sexual identities.

Oral drug therapy in elderly with dysphagia: between a rock and a hard place!

Demographic indicators forecast that by 2050, the elderly will account for about one-third of the global population. Geriatric patients require a large number of medicines, and in most cases, these products are administered as solid oral solid dosage forms, as they are by far the most common formulations on the market. However, this population tends to suffer difficulties with swallowing. Caregivers in hospital geriatric units routinely compound in solid oral dosage forms for dysphagic patients by crushing the tablets or opening the capsules to facilitate administration. The manipulation of a tablet or a capsule, if not clearly indicated in the product labeling, is an off-label use of the medicine, and must be supported by documented scientific evidence and requires the patient's informed consent. Compounding of marketed products has been recognized as being responsible for an increased number of adverse events and medical errors. Since extemporaneous compounding is the rule and not the exception in geriatrics departments, the seriousness and scope of issues caused by this daily practice are probably underestimated. In this article, the potential problems associated with the manipulation of authorized solid oral dosage forms are discussed.

The development and implementation of a decision-making capacity assessment model

Background

Decision-making capacity assessment (DMCA) is an issue of increasing importance for older adults. Current challenges need to be explored, and potential processes and strategies considered in order to address issues of DMCA in a more coordinated manner.

Methods

An iterative process was used to address issues related to DMCA. This began with recognition of challenges associated with capacity assessments (CAs) by staff at Covenant Health (CH). Review of the literature, as well as discussions with and a survey of staff at three CH sites, resulted in determination of issues related to DMCA. Development of a DMCA Model and demonstration of its feasibility followed.

Results

A process was proposed with front-end screening/problem- solving, a well-defined standard assessment, and definition of team member roles. A Capacity Assessment Care Map was formulated based on the process. Documentation was developed consisting of a Capacity Assessment Process Worksheet, Capacity Interview Worksheet, and a brochure. Interactive workshops were delivered to familiarize staff with the DMCA Model. A successful demonstration project led to implementation across all sites in the Capital Health region, and eventual provincial endorsement.

Conclusions

Concerns identified in the survey and in the literature regarding CA were addressed through the holistic interdisciplinary approach offered by the DMCA Model.

Features and outcomes of patients who underwent cardiac device deactivation

IMPORTANCE

Little is known about patients who undergo cardiovascular implantable electronic device deactivation.

OBJECTIVE

To describe features and outcomes of patients who underwent cardiovascular implantable electronic device deactivation.

DESIGN, SETTING, AND PARTICIPANTS

Retrospective review of medical records of 150 patients at a tertiary academic medical center (Mayo Clinic, Rochester, Minnesota). EXPOSURE Cardiovascular implantable electronic device deactivation.

MAIN OUTCOMES AND MEASURES

Demographic and clinical data and information regarding advance directives, ethics consultations, palliative medicine consultations, and cardiovascular implantable electronic device deactivations.

RESULTS

Of the 150 patients (median age, 79 years; 67% were male), 149 (99%) had poor or terminal prognoses. Overall, 118 patients (79%) underwent deactivation of tachycardia therapies only, and 32 (21%) underwent deactivation of bradycardia therapies with or without tachycardia therapies (6 patients [4%] were pacemaker-dependent). Half of the deactivation requests (51%) were made by surrogates. A majority of deactivations (55%) were carried out by nurses. Although 85 patients (57%) had advance directives, only 1 mentioned the device in the directive. Ethics consultations occurred in 3 patients (2%) and palliative medicine consultations in 64 (43%). The proportions of patients who died within 1 month of device deactivation were similar for those who underwent deactivation of tachycardia therapies only and those who underwent deactivation of bradycardia therapies with or without tachycardia therapies (85% vs 94%; P = .37).

CONCLUSIONS AND RELEVANCE

Most requests for cardiovascular implantable electronic device deactivation were for implantable cardioverter-defibrillator-delivered tachycardia therapies only. Many of these requests were made by surrogates. Advance directives executed by patients with these devices rarely addressed device management. Regardless of device therapy, most patients died shortly after device deactivation. Hence, a device deactivation decision may reflect the seriousness of a given patient's underlying illness. Patients with devices should engage in advance care planning to ensure that future care is consistent with their preferences.

Geriatric chest imaging: when and how to image the elderly lung, age-related changes, and common pathologies

Even in a global perspective, societies are getting older. We think that diagnostic lung imaging of older patients requires special knowledge. Imaging strategies have to be adjusted to the needs of frail patients, for example, immobility, impossibility for long breath holds, renal insufficiency, or poor peripheral venous access. Beside conventional radiography, modern multislice computed tomography is the method of choice in lung imaging. It is especially important to separate the process of ageing from the disease itself. Pathologies with a special relevance for the elderly patient are discussed in detail: pneumonia, aspiration pneumonia, congestive heart failure, chronic obstructive pulmonary disease, the problem of overlapping heart failure and chronic obstructive pulmonary disease, pulmonary drug toxicity, incidental pulmonary embolism pulmonary nodules, and thoracic trauma.

Health related quality of life in older Mexican Americans with diabetes: a cross-sectional study

BACKGROUND

The older Hispanic population of the U.S. is growing at a tremendous rate. While ethnic-related risk and complications of diabetes are widely-acknowledged for older Hispanics, less is known about how health related quality of life is affected in this population.

METHODS

Cross-sectional study assessing differences in health related quality of life between older Mexican Americans with and without diabetes. Participants (n = 619) from the Hispanic Established Population for the Epidemiological Study of the Elderly were interviewed in their homes. The primary measure was the Medical Outcomes Study Short Form (SF-36).

RESULTS

The sample was 59.6% female with a mean age of 78.3 (SD = 5.2) years. 31.2% (n = 193) of the participants were identified with diabetes. Individuals with diabetes had significantly (F = 19.35, p < .001) lower scores on the Physical Composite scale (mean = 37.50, SD = 12.69) of the SF-36 compared to persons without diabetes (mean = 43.04, SD = 12.22). There was no significant difference between persons with and without diabetes on the Mental Composite scale of the SF-36.

CONCLUSION

Diabetes was associated with lower health related quality of life in older Mexican Americans. The physical components of health related quality of life uniformly differentiated those with diabetes from those without, whereas mental component scores were equivocal.

The state of advance care planning: one decade after SUPPORT

The Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatment (SUPPORT) was a landmark study regarding end-of-life decision making and advance care planning. Phase I of the study looked at the state of end of life in various hospitals, and phase II implemented a nurse-facilitated intervention designed to improve advance care planning, patient-physician communication, and the dying process. The observational phase found poor quality of care at the end of life and the intervention failed to improve the targeted outcomes. The negative findings brought public attention to the need to improve care for the dying and spawned a wealth of additional research on decision-making at the end of life. In the decade since SUPPORT, researchers have defined the attributes of a "good death," addressed the role of advance directives in advance care planning, and studied the use of surrogate decision-making at the end of life. This rekindled the discussion on advance care planning and challenged health care providers to design more flexible approaches to end of life care.

Effect of ethics consultations in the intensive care unit

Although evidence-based research is limited, results suggest that ethics consultations are associated with reductions in hospital days and intensive care unit days and in life-sustaining treatments in those patients who ultimately will not survive to discharge. Furthermore, the majority of healthcare providers and patients/surrogates agreed that ethics consultations in the intensive care unit were helpful in addressing treatment conflicts. Ethics consultations also reduce hospital costs without diminishing the quality of care. Hence, ethics consultations seem to be useful in resolving conflicts that may be inappropriately prolonging nonbeneficial or unwanted treatments at the end of life. Further research on whether ethics consultations are beneficial in other settings is needed to establish the optimal scope of this intervention. Also, the benefits described above were achieved by highly skilled and experienced consultants. It is not certain, therefore, how successful other hospitals will be when adopting this intervention.

Resuscitation of the Elderly

The changing demographics of America's population over the past couple of decades have propelled geriatric medicine into the fore-front. Due to this, emergency medicine physicians will face numerous challenges managing an increasing number of critically ill elderly patients. This article will focus on success of resuscitation in this population, important pathophysiologic changes that occur with aging, as well as ethical considerations in end-of-life care.

Ethics consultation in the intensive care unit

PURPOSE OF REVIEW

To review the medical literature for recent reports of the role of ethics consultations in the intensive care setting.

RECENT FINDINGS

Ethical principles can provide important guidelines for dealing with value conflicts in medical treatment decisions, particularly treatment decisions to limit life-sustaining treatment in the intensive care unit. Until recently, advocates of ethics consultations have had to rely on inconclusive supporting data. In the past few years, however, a single-site and multi-site prospective randomized controlled trial of the ethics consultations offered in response to treatment conflicts in the intensive care unit demonstrated significant reductions in hospital days, hospital costs, and ventilator days in patients who did not survive to hospital discharge. The consultations were very well received by all the parties.

SUMMARY

Ethics consultations seem to be useful in resolving conflicts that may be inappropriately prolonging nonbeneficial or unwanted treatments at the end of life. Further research on whether ethics consultations are beneficial in other settings is needed to establish the optimal scope of this intervention. Also, because these benefits were achieved by highly skilled and experienced consultants, it is not certain how successful other hospitals will be when adopting this intervention.

Medical and ethical aspects of long-term enteral tube feeding

Clinicians frequently care for patients in whom long-term enteral tube feeding is being considered. The substantial increase in the use of endoscopically placed tubes for long-term feeding reflects the aging population, advances in medicine and technology, and inadequate advance care planning. Physicians should address advance care planning with all patients at the earliest opportunity. Prospective randomized trials measuring clinical outcomes for patients receiving long-term tube feeding are understandably limited. In addition, confusion regarding medical and ethical guidelines for long-term tube feeding often exists among clinicians, patients, and surrogate decision makers. Therefore, we discuss the physiology and clinical tolerance of limited oral nutritional intake, the prevalence of and Indications for long-term tube feeding, the endoscopic procedures and their complications, the reported medical and quality-of-life outcomes, and the critical importance of advance care planning. We present our multidisciplinary approach that combines medical, nutritional, and ethical principles for the care of these patients.

Colorectal cancer in geriatric patients: Endoscopic diagnosis and surgical treatment

AIM: To investigate the prevalence of colorectal cancer in geriatric patients undergoing endoscopy and to analyze their outcome.

METHODS: All consecutive patients older than 80 years who underwent lower gastrointestinal endoscopy between January 1995 and December 2002 at our institution were included. Patients with endoscopic diagnosis of colorectal cancer were evaluated with respect to indication, localization and stage of cancer, therapeutic consequences, and survival.

RESULTS: Colorectal cancer was diagnosed in 88 patients (6% of all endoscopies, 55 women and 33 men, mean age 85.2 years). Frequent indications were lower gastrointestinal bleeding (25%), anemia (24%) or sonographic suspicion of tumor (10%). Localization of cancer was predominantly the sigmoid colon (27%), the rectum (26%), and the ascending colon (20%). Stage Dukes A was rare (1%), but Dukes D was diagnosed in 22% of cases. Curative surgery was performed in 54 patients (61.4%), in the remaining 34 patients (38.6%) surgical treatment was not feasible due to malnutrition and asthenia or cardiopulmonary comorbidity (15 patients), distant metastases (11 patients) or refusal of operation (8 patients). Patients undergoing surgery had a very low in-hospital mortality rate (2%). Operated patients had a one-year and three-year survival rate of 88% and 49%, and the survival rates for non-operated patients amounted to 46% and 13% respectively.

CONCLUSION: Nearly two-thirds of 88 geriatric patients with endoscopic diagnosis of colorectal cancer underwent successful surgery at a very low perioperative mortality rate, resulting in significantly higher survival rates. Hence, the clinical relevance of lower gastrointestinal endoscopy and oncologic surgery in geriatric patients is demonstrated.
