Thyroid Function and Cognitive Decline: A Narrative Review.

OBJECTIVE: As the population of older adults in the United States continues to rise, understanding modifiable risk factors that contribute to cognitive decline and dementia becomes increasingly important. This narrative review summarizes existing literature on the association between thyroid function in the euthyroid range, hypothyroidism and hyperthyroidism, and cognitive outcomes in older adults. METHODS: A comprehensive literature search of the PubMed and Ovid/Medline databases was conducted. Randomized controlled trials, systematic reviews, meta-analyses, and observational studies published in English between January 2000 and December 2023 were included. RESULTS: Overall, existing studies yielded conflicting results, failing to delineate a concrete relationship between thyroid function and cognitive outcomes and/or dementia in older adults. There may be a possible association between higher thyroid stimulating hormone in the reference range and lower risk of incident dementia, which may be more pronounced in women. Majority of studies elucidated a possible association between low thyroid stimulating hormone and incident dementia, with suggestion that duration of hyperthyroidism may contribute to increasing dementia risk. Even though evidence on the association of hypothyroidism and cognitive decline are disparate, current data do not support treatment of subclinical hypothyroidism to improve cognitive outcomes in older adults. CONCLUSION: Despite numerous studies, there is no conclusive evidence that supports a direct relationship between hyperthyroidism or hypothyroidism and cognitive decline. Study limitations include heterogeneity in study designs, measurement methodologies, and cognitive assessment tools. Future research is needed to better delineate whether an association exists and whether treatment of thyroid dysfunction ameliorates cognitive impairment.

Post-acute and long-term care: a practical and novel curriculum for medical students.

Most physicians will not practice in post-acute or long-term care (PALTC), yet many will care for older adults who transition across these settings. However, medical student education on PALTC is extremely limited. This is a pilot study of a curriculum on PALTC. The curriculum was developed by a geriatrician and social worker. Students participated in a case-based, didactic lecture with interactive components to learn about various care settings, then engaged in a small group exercise to evaluate a challenging transition of care scenario. 168 students participated in the lecture and 145 provided feedback (86.9%). On average, students scored a 1.8/5 (35%) on the pre-course knowledge assessment and 4.3/5 (86%) at the conclusion of the course. Qualitative feedback was analyzed thematically. Students reported positive sentiments regarding the clarity, relevance, engagement, and practicality of the session. Furthermore, students anticipated that the course would improve their own practice patterns and care of older adults. Students felt more empowered to work with interprofessional colleagues because of this course. Opportunities for improvement included a desire for more interactivity and additional reference resources. The course was well-received; students indicated that it would positively influence their practice patterns. This course structure is both highly practical and replicable.

Guardianship: The Implications of Resident Physician Perceptions of Caring for Incapacitated Older Adults Without Advocates.

As the incidence of dementia rises, increased utilization of surrogate decision-makers, including legal guardians, is anticipated. This manuscript presents an analysis of resident physicians' experiences and perceptions regarding requirements, roles, and responsibilities of caring for older adults in need of, or already under, legal guardianship. This is a cross-sectional study, conducted at a tertiary academic medical center. A survey was sent, via Qualtrics, to all emergency medicine, family medicine, internal medicine, general surgery, and medicine-pediatric resident physicians. Eighty-eight out of three hundred thirty-three (26.4%) eligible residents physicians completed the survey. Most (98.9%) reported caring for patients under guardianship, yet many resident physicians reported significant uncertainty regarding the roles and responsibilities of guardianship, including its potential benefits and limitations. They also displayed misconceptions and overconfidence about guardians' abilities to facilitate disposition, ensure financial security, and assign code status, among other matters. Our study highlights the importance of structured and directed education on the topic of guardianship for medical trainees.

Prioritizing geriatrics in medical education improves care for all.

Within the United States, there is a deficit of Geriatricians providing care for older adults, and this deficit will only grow as the population continues to age, meaning all clinicians, particularly Internal Medicine (IM) and Family Medicine (FM) trained physicians, will provide the bulk of primary care for older adults. However, geriatric training requirements for clinicians fall short, and in the case of IM were reduced as of 2022). Serving as a call to action, this article provides insight on ways to enhance geriatric education for all graduate medical trainees, utilizing both conventional teaching and newer, non-traditional media, such as national online journal clubs, podcasts, and online teaching curricula, as well as expanding sites of training to include evidence-based models of care, such as the Program of All-Inclusive Care for the Elderly (PACE). Providing geriatric education improves care for older adults and our future selves, ensuring trainees are prepared to care and advocate for this diverse and often vulnerable population.

Guardianship: A medicolegal review for clinicians.

Guardianship may pose an ethical dilemma for physicians, who must balance protecting vulnerable patients from potential safety concerns with respecting their autonomy. Older adults with dementia are particularly susceptible to loss of independence and the ability to participate in medical decision making. To have the capacity for medical decision making, individuals must understand relevant information, appreciate their circumstances, demonstrate reasoning, and express a consistent choice free from coercion. Although capacity assessments are usually task-specific, geriatricians and other specialists may be asked to comment on capacity more globally. These determinations may be used to support a Petition for the Appointment of a Guardian of a Legally Incapacitated Adult, the legal process of pursuing guardianship in probate court. Assigned guardians may be known to the incapacitated individual (e.g., a family member or friend) or may be professional guardians with no prior relationship to the ward. Guardians are encouraged to use substituted decision-making, taking into account the ward's previously expressed values and preferences. Although a number of viable alternatives to guardianship exist, numerous systemic barriers may prevent these from being fully explored. The ongoing need for guardianship should be periodically revisited and reassessed. Data about guardians and wards is shockingly sparse, as there are no centralized databases. Laws and regulations for guardianships vary significantly between states. Physicians can serve as important allies and advocates for patients with cognitive impairment at risk of incapacity, can help preserve their autonomy for as long as possible, and ensure appropriate protections are in place if the patient does lose their decision-making ability.

Geriatric Preoperative Optimization: A Review.

This review summarizes best practices for the perioperative care of older adults as recommended by the American Geriatrics Society, American Society of Anesthesiologists, and American College of Surgeons, with practical implementation strategies that can be readily implemented in busy preoperative or primary care clinics. In addition to traditional cardiopulmonary screening, older patients should undergo a comprehensive geriatric assessment. Rapid screening tools such as the Mini-Cog, Patient Health Questionnaire-2, and Frail Non-Disabled Survey and Clinical Frailty Scale, can be performed by multiple provider types and allow for quick, accurate assessments of cognition, functional status, and frailty screening. To assess polypharmacy, online resources can help providers identify and safely taper high-risk medications. Based on preoperative assessment findings, providers can recommend targeted prehabilitation, rehabilitation, medication management, care coordination, and/or delirium prevention interventions to improve postoperative outcomes for older surgical patients. Structured goals of care discussions utilizing the question-prompt list ensures that older patients have a realistic understanding of their surgery, risks, and recovery. This preoperative workup, combined with engaging with family members and interdisciplinary teams, can improve postoperative outcomes.

Perioperative Optimization of Senior Health (POSH): A Descriptive Analysis of Cancelled Surgery.

BACKGROUND: Geriatric collaborative care models improve postoperative outcomes for older adults. However, there are limited data exploring how preoperative geriatric assessment may affect surgical cancellations. METHODS: This is a single-center retrospective cohort analysis. Patients enrolled in the Perioperative Optimization of Senior Health (POSH) program from 2011 to 2016 were included. POSH is a collaborative care model between geriatrics, surgery, and anesthesiology. Baseline demographic and medical data were collected during the POSH pre-op appointment. Patients who attended a POSH pre-op visit but did not have surgery were identified, and a chart review was performed to identify reasons for surgical cancellation. Baseline characteristics of patients who did and did not undergo surgery were compared. RESULTS: Of 449 eligible POSH referrals within the study period, 33 (7.3%) did not proceed to surgery; cancellation rates within the POSH program were lower than institutional cancellation rates for adults over age 65 who did not participate in POSH. Patients who did not have surgery were significantly older, more likely to have functional limitations, and had higher rates of several comorbidities compared with those who proceeded to surgery (P < 0.05). Reasons for surgical cancellations included a similar number of patient- and provider-driven causes. CONCLUSIONS: Many reasons for surgical cancellation were related to potentially modifiable factors, such as changes in goals of care or concerns about rehabilitation, emphasizing the importance of shared decision-making in elective surgery for older adults. These results highlight the important role geriatric collaborative care can offer to older adults with complex needs.

Characteristics and Outcomes of Dementia Patients Who Receive Inpatient Palliative Care Consultation.

BACKGROUND/OBJECTIVES: Acute hospitalization may be an ideal opportunity to introduce palliative care to dementia patients, who may benefit from symptom management and goals of care discussions. We know little about patients who receive inpatient palliative care consultations (IPCCs). DESIGN: Retrospective analysis using electronic medical record. SETTING: Tertiary academic medical center and affiliated community hospital. PARTICIPANTS: Patients with dementia by International Classification of Diseases diagnosis, 65 years or older, hospitalized between July 1, 2015, and December 31, 2015. MEASUREMENTS: We used χ2 and t-test/Mann-Whitney U test to compare characteristics (living arrangement, advanced dementia markers, diagnoses of delirium and dementia with behavior disturbance, and admitting diagnosis) and outcomes (change in code status, length of stay [LOS], discharge disposition, and discharge medications for symptom management) of patients who did and did not receive IPCC. Patients were matched on sex, age, and race. RESULTS: Among 927 hospitalized patients with dementia, 17% received IPCC (N = 157). Patients who received IPCC were more likely to be admitted from a nursing facility (35.7% vs 12.7%; P < .0001), experience delirium (71.3% vs 57.3%; P = .01), have behavior disturbance (23.6% vs 13.4%; P = .02), have a pressure ulcer at admission (26.1% vs 11.5%; P = .001), have hypernatremia (12.7% vs 3.2%; P = .002), and be bedbound (20.4% vs 3.2%; P < .000). Patients who received IPCC had a longer LOS (median = 5.9 vs 4.3 days; P = .004) and were more likely to be discharged to hospice (56% vs 3.1%; P < .0001). Patients with IPCC were more likely to have a discharge code status of do not attempt resuscitation (89% vs 46%). There was no significant difference in comfort medications at discharge between groups. CONCLUSIONS: Patients who received IPCC had evidence of more advanced dementia. These patients were more likely to change their code status and enroll in hospice. IPCC may be useful to prioritize patient-centered care and discuss what matters most to patients and families.

Planning for a Safe Discharge: More Than a Capacity Evaluation.

Discharge decision making for hospitalized older adults can be a complicated process involving functional assessments, capacity evaluation, and coordination of resources. Providers may feel pressured to recommend that an older adult with complex care needs be discharged to a skilled nursing facility rather than home, potentially contradicting the patient's wishes. This can lead to a professional and ethical dilemma for providers, who value patient autonomy and shared decision making. We describe a discharge decision-making framework focused on interprofessional evaluation and management, longitudinal follow-up, and education and support for patients and families. By gathering and synthesizing information, eliciting goals and preferences, and identifying community resources, the healthcare team can help maximize independence for vulnerable older adults.

Delaying Elective Surgery in Geriatric Patients: An Opportunity for Preoperative Optimization.

Deciding whether to pursue elective surgery is a complex process for older adults. Comprehensive geriatric assessment (CGA) can help refine estimates of benefits and risks, at times leading to a delay of surgery to optimize surgical readiness. We describe a cohort of geriatric patients who were evaluated in anticipation of elective abdominal surgery and whose procedures were delayed for any reason. Themes behind the reasons for delay are described, and a holistic framework to guide preoperative discussion is suggested.

A novel curriculum to train physician assistant students how to write effective discharge summaries.

Background: Physician assistants (PAs) are an integral part of inpatient care teams, but many PAs do not receive formal education on authoring discharge summaries. High-quality discharge summaries can mitigate patient risk during transitions of care by improving inter-provider communication. Objective: To understand the current state of discharge summary education at our institution, and describe a novel curriculum to teach PA students to write effective discharge summaries. Design: Students completed a pre-survey to assess both knowledge and comfort levels regarding discharge summaries. They wrote a discharge summary and received feedback from two evaluators, an inpatient provider (IPP) familiar with the described patient and a simulated primary care provider (PCP). Students completed a post-survey reassessing knowledge and comfort. Results: Prior to instituting this curriculum, the majority of students (92.9%) reported rarely or never receiving feedback on discharge summaries. Eighty-four of 88 (95.5%) eligible students participated. There was discordance between IPP and simulated PCP feedback on their assessment of the quality of discharge summaries; simulated PCPs gave significantly lower global quality ratings (7.9 versus 8.5 out of 10, p = 0.006). Key elements were missing from >10% of discharge summaries. Student response was favorable. Conclusion: Clinically relevant deficiencies were common in students' discharge summaries, highlighting the need for earlier, structured training. IPPs and simulated PCPs gave discordant feedback, emphasizing differing needs of different providers during transitions of care. This novel curriculum improved students' knowledge and confidence.

Discharge summary training curriculum: a novel approach to training medical students how to write effective discharge summaries.

BACKGROUND: Resident physicians at teaching hospitals write many discharge summaries (DCSs), but receive little formal training or feedback. Poor DCS quality poses a potential patient safety risk. METHODS: We developed a curriculum to train fourth-year medical students (MS4s) how to write DCSs and integrated this curriculum into a transition-to-residency course. An inpatient attending physician (IPA) and non-inpatient physician (coach) used structured tools to assess for the presence of key elements within the DCS, evaluate the overall quality of the DCS, and judge the student's progression towards entrustable professional activities and transitional year milestones. We identified overall areas of weakness and correlated scores between IPAs and coaches. Improvements in student knowledge and DCS writing confidence were determined using pre- and post-curriculum surveys. RESULTS: Of 102 eligible students, 78 completed the assignment, 61 wrote a new DCS and 17 reviewed previously written DCSs. Patient condition at discharge was missing in more than 20.0% of DCSs. Coaches were less likely than IPAs to assess students as entrustable (58.3% versus 95.8%; p = 0.0027). IPAs assigned higher overall quality ratings than coaches (8.0 versus 6.0 out of 10.0, p< 0.0001). Post-intervention, 82.2% of students reported they learned how to write high-quality DCSs and 93.3% of students reported they would change the way they write DCSs. CONCLUSIONS: Graduating medical students have limited skill and comfort in writing DCSs. Structured training on how to write DCSs before postgraduate residency training is a key step towards ultimately improving transitions of care. Training should teach learners to write high-quality DCSs that serve the needs of both inpatient and outpatient providers. Resident physicians at teaching hospitals are expected to independently author [discharge summaries] DCSs, yet few receive formal training.

Preoperative Cognitive Impairment As a Predictor of Postoperative Outcomes in a Collaborative Care Model.

OBJECTIVES: To compare postoperative outcomes of individuals with and without cognitive impairment enrolled in the Perioperative Optimization of Senior Health (POSH) program at Duke University, a comanagement model involving surgery, anesthesia, and geriatrics. DESIGN: Retrospective analysis of individuals enrolled in a quality improvement program. SETTING: Tertiary academic center. PARTICIPANTS: Older adults undergoing surgery and referred to POSH (N = 157). MEASUREMENTS: Cognitive impairment was defined as a score less than 25 out of 30 (adjusted for education) on the St. Louis University Mental Status (SLUMS) Examination. Median length of stay (LOS), mean number of postoperative complications, rates of postoperative delirium (POD, %), 30-day readmissions (%), and discharge to home (%) were compared using bivariate analysis. RESULTS: Seventy percent of participants met criteria for cognitive impairment (mean SLUMS score 20.3 for those with cognitive impairment and 27.7 for those without). Participants with and without cognitive impairment did not significantly differ in demographic characteristics, number of medications (including anticholinergics and benzodiazepines), or burden of comorbidities. Participants with and without cognitive impairment had similar LOS (P = .99), cumulative number of complications (P = .70), and 30-day readmission (P = .20). POD was more common in those with cognitive impairment (31% vs 24%), but the difference was not significant (P = .34). Participants without cognitive impairment had higher rates of discharge to home (80.4% vs 65.1%, P = .05). CONCLUSION: Older adults with and without cognitive impairment referred to the POSH program fared similarly on most postoperative outcomes. Individuals with cognitive impairment may benefit from perioperative geriatric comanagement. Questions remain regarding the validity of available measures of cognition in the preoperative period.

Familial Adenomatous Polyposis Manifesting as Lactococcus Endocarditis: A Case Report and Review of the Association of Lactococcus with Underlying Gastrointestinal Disease.

A 45-year-old male with a prosthetic aortic valve presented to the hospital with several months of generalized malaise. On admission, he was noted to have anemia of unclear etiology and subsequently became febrile with multiple blood cultures growing Lactococcus garvieae. Inpatient workup was concerning for infectious endocarditis (IE) secondary to Lactococcus. The patient was discharged home with appropriate antimicrobial therapy; however, he was readmitted for persistent, symptomatic anemia and underwent colonoscopy, which revealed innumerable colonic polyps consistent with Familial Adenomatous Polyposis (FAP) that was later confirmed with genetic testing. Surveillance computed tomography (CT) imaging of the aortic repair later demonstrated valve dehiscence with surrounding fluid collection; he underwent redo surgery and was found to have destruction of the aortic annulus and a large pseudoaneurysm. Histopathology of the valve prosthesis confirmed IE. It is suspected that the patient developed Lactococcus IE from enteric translocation. Review of the literature provides several reports of Lactococcus infections in association with underlying gastrointestinal disease, including colorectal cancer. Given this association, we raise the question of whether the diagnosis of Lactococcus IE should evoke suspicion and encourage evaluation for gastrointestinal pathology, as occurs with Streptococcus bovis.

Diagnosing pulmonic valve infective endocarditis with positron emission tomography-CT.

Infective endocarditis (IE) affects the pulmonic valve in less than 2% of cases. Not only is pulmonary valve IE rare, it is also challenging to visualise with commonly used imaging modalities. In this vignette, we present a 50-year-old patient with a history of repaired Tetralogy of Fallot who underwent a prolonged hospitalisation and extensive work up for fever of unknown origin. Although we suspected IE as the source of his fevers, he had persistently negative transthoracic and transoesophageal echocardiograms. We were ultimately able to establish the diagnosis with the use of positron emission tomography-CT (PET-CT). Although PET-CT is not part of the traditional work up for IE, it can be a useful imaging modality when there is a high index of suspicion for IE with negative echocardiography findings.
