Impact of a pilot multimodal intervention to decrease antibiotic use for respiratory infections in a geriatric clinic.

Background: More than 80% of antibiotics are prescribed in the outpatient setting, of which 30% are inappropriate. The National Action Plan for Combating Antimicrobial Resistance called for a 50% decrease in outpatient antibiotic use by 2020. Inappropriate antibiotics are associated with adverse reactions and Clostridioides difficile infection, especially among older adults. Study design: Before and after study. Methods: We performed a quality improvement initiative at the University of Colorado Seniors Clinic. Providers received education on antibiotic guidelines, electronic antibiotic order sets were introduced with standardized stop dates. Antibiotic use data were collected for 6 months before and 6 months after the intervention, from December to May to avoid seasonal variation. Descriptive statistics and linear mixed-effects regression models were used for this comparison. Results: Total antibiotic prescriptions for acute respiratory conditions decreased from 137 prescriptions before the intervention (December 1, 2017, to May 31, 2018) to 112 prescriptions after the intervention (December 1, 2018, to May 31, 2019), driven primarily by decreases in antibiotic prescriptions for pneumonia, sinusitis, and bronchitis. Prescriptions for broad-spectrum antibiotics declined following the intervention including decreases in levofloxacin from 12 (9%) to 3 (3%) and amoxicillin-clavulanate from 15 (12%) to 7 (7%). We detected significant reductions in prescribed antibiotic durations (days) after the intervention for sinusitis (estimate, -2.0; 95% CI, -3.1 to -1.0; P = .0003), pharyngitis (estimate, -2.5; 95% CI, -4.6 to -0.5; P = .018), and otitis (-3.2; 95% CI, -5.2 to -1.3; P = .008). Conclusions: Low-cost interventions were initially successful in changing patterns of antibiotic use and decreasing overall antibiotic prescribing among older patients in the outpatient setting. Long-term follow-up studies are needed to determine the sustainability and clinical impact of these interventions.

Interprofessional student-led outreach to high-risk older adults during the COVID-19 pandemic.

In response to a statewide stay-at-home order during the COVID-19 pandemic, the Seniors Clinic launched an interprofessional student-led, telephone-based outreach initiative targeting older adults deemed high risk for social isolation. The initiative primarily aimed to enhance students' geriatric and interprofessional education during a time when clinical learning opportunities were limited, as well as supporting geriatric patients and providers through outreach during the COVID-19 quarantine period. Nurse practitioner, medical, and pharmacy students participated in virtual patient contact, geriatric case-based learning, and team-based interprofessional development. We conducted pre-and post-outreach assessments with students and geriatric providers to determine the effects of this initiative. After participating in the 3-month outreach initiative, interprofessional students reported increased confidence in conducting outreach calls, participating in interdisciplinary team discussions, and reviewing geriatric cases. This student-led telephone-based outreach to older adults improved students' exposure to and confidence with interprofessional teamwork and geriatric medicine. Our experience can inform future interprofessional initiatives to improve outreach to populations affected by public health emergencies.

Lesbian, Gay, Bisexual, and Transgender Older Adults' Experiences With Elder Abuse and Neglect.

BACKGROUND/OBJECTIVES: Little is known about elder abuse and neglect in the lesbian, gay, bisexual, and transgender (LGBT) community; however, this population faces a greater risk of abuse and likely experiences abuse differently and needs different resources. We conducted focus groups to investigate LGBT older adults' perspectives on and experience with elder mistreatment. METHODS: We conducted three focus groups with 26 participants recruited from senior centers dedicated to LGBT older adults. A semistructured questionnaire was developed, and focus groups were audio recorded, professionally transcribed, and analyzed using grounded theory. RESULTS: Key themes that emerged included: definitions and etiologies of abuse, intersectionality of discrimination from multiple minority identities, reluctance to report, and suggestions for improving outreach. Participants defined elder abuse in multiple ways, including abuse from systems and by law enforcement and medical providers. Commonly reported etiologies included: social isolation due to discrimination, internalization of stigma, intersection of discrimination from multiple minority identities, and an abuser's desire for power and control. Participants were somewhat hesitant to report to police; however, most felt strongly that they would not report abuse to their medical provider. Most reported that they would feel compelled to report if they knew someone was being abused; however, they did not know who to report to. Strategies participants suggested to improve outreach included: increasing awareness about available resources and researchers engaging with the LGBT community directly. CONCLUSION: LGBT older adults conceptualize elder abuse differently and have different experiences with police and medical providers. Improved outreach to this potentially vulnerable population is critical to ensuring their safety. J Am Geriatr Soc 67:2338-2345, 2019.

Characteristics and Patterns of Marijuana Use in Community-Dwelling Older Adults.

OBJECTIVES: To understand patterns of marijuana use in community-dwelling older adults in Colorado. DESIGN: Anonymous survey. SETTING: Two academic geriatric primary care clinics. PARTICIPANTS: English-speaking individuals. MEASUREMENTS: We assessed self-reported characteristics and patterns of marijuana use and effect on targeted symptoms. Survey analysis focused on current users, defined as individuals who had used marijuana in the past 3 years. RESULTS: Three hundred forty-five individuals completed the survey (55% response rate); 113 (32%) had used marijuana in the past, of whom 55 (16%) had used since legalization. More than half of current users were aged 75 and older, and one-quarter were aged 85 and older. Most current users were white women. Of current users, 44% used marijuana products at least weekly for common conditions including chronic pain, depression, anxiety, and insomnia, and most found marijuana helpful for these conditions. Most respondents reported obtaining marijuana recreationally (67%) without a prescription. Nine respondents reported negative side effects attributable to marijuana use. CONCLUSION: To our knowledge, this is the first study to characterize marijuana use of older adults in a state in which it is legal for medical and recreational use. Marijuana was used for several common geriatric conditions, and respondents reported few side effects. The small number of survey respondents, the lack of generalizability in states where marijuana sales are illegal, and participation bias were the main study limitations. Further research is needed to better understand useful or harmful effects in this population. J Am Geriatr Soc 66:2167-2171, 2018.

Teaching Medical Students About "The Conversation": An Interactive Value-Based Advance Care Planning Session.

BACKGROUND: Advance care planning (ACP) promotes care consistent with patient wishes. Medical education should teach how to initiate value-based ACP conversations. OBJECTIVE: To develop and evaluate an ACP educational session to teach medical students a value-based ACP process and to encourage students to take personal ACP action steps. DESIGN: Groups of third-year medical students participated in a 75-minute session using personal reflection and discussion framed by The Conversation Starter Kit. The Conversation Project is a free resource designed to help individuals and families express their wishes for end-of-life care. SETTING AND PARTICIPANTS: One hundred twenty-seven US third-year medical students participated in the session. MEASUREMENTS: Student evaluations immediately after the session and 1 month later via electronic survey. RESULTS: More than 90% of students positively evaluated the educational value of the session, including rating highly the opportunities to reflect on their own ACP and to use The Conversation Starter Kit. Many students (65%) reported prior ACP conversations. After the session, 73% reported plans to discuss ACP, 91% had thought about preferences for future medical care, and 39% had chosen a medical decision maker. Only a minority had completed an advance directive (14%) or talked with their health-care provider (1%). One month later, there was no evidence that the session increased students' actions regarding these same ACP action steps. CONCLUSION: A value-based ACP educational session using The Conversation Starter Kit successfully engaged medical students in learning about ACP conversations, both professionally and personally. This session may help students initiate conversations for themselves and their patients.

Evaluation and management of the elderly patient presenting with cognitive complaints.

Cognitive complaints are common in the geriatric population. Older adults should routinely be asked about any concerns about their memory or thinking, and any cognitive complaint from the patient or an informant should be evaluated rather than be attributed to aging. Several screening instruments are available to document objective impairments and guide further evaluation. Management goals for patients with cognitive impairment are focused on maintaining function and independence, providing caregiver support, and advance care planning. There are currently no treatments to effectively prevent or treat dementia. Increasing appreciation of the heterogeneity of Alzheimer disease may lead to novel treatment approaches.

Postoperative falls in the acute hospital setting: characteristics, risk factors, and outcomes in males.

BACKGROUND: Hospital falls are an important cause of morbidity in older surgical patients. The objectives of this study were to describe the characteristics, risk factors, and outcomes for postoperative falls. METHODS: A retrospective study was performed on patients who were admitted to the hospital for more than 23 hours after surgery. Patients who fell within 30 days of their surgery were considered to have experienced a postoperative fall. RESULTS: Over 5 years and 9,625 inpatient surgical procedures, 154 patients experienced 190 falls. Injuries resulting from postoperative falls included major injury (hip fracture), less than 1%; injury requiring intervention, 2%; injury not requiring intervention, 27%; and no injury, 70%. Variables associated with postoperative falls included older age, functional dependence, lower albumin level, and higher American Society of Anesthesia score. CONCLUSIONS: One or more postoperative falls occurred in 1.6% of surgical inpatients and can lead to significant morbidity. Recognition of fall risk factors will help design postoperative fall prevention programs by identifying patients at highest risk for postoperative falls.

Redefining geriatric preoperative assessment using frailty, disability and co-morbidity.

OBJECTIVES: (1) Determine the relationship of geriatric assessment markers to 6-month postoperative mortality in elderly patients. (2) Create a clinical prediction rule using geriatric markers from preoperative assessment. BACKGROUND: Geriatric surgery patients have unique physiologic vulnerability requiring preoperative assessment beyond the traditional evaluation of older adults. The constellation of frailty, disability and comorbidity predict poor outcomes in elderly hospitalized patients. METHODS: Prospectively, subjects > or =65 years undergoing a major operation requiring postoperative intensive care unit admission were enrolled. Preoperative geriatric assessments included: Mini-Cog Test (cognition), albumin, having fallen in the past 6-months, hematocrit, Katz Score (function), and Charlson Index (comorbidities). Outcome measures included 6-month mortality (primary) and postdischarge institutionalization (secondary). RESULTS: One hundred ten subjects (age 74 +/- 6 years) were studied. Six-month mortality was 15% (16/110). Preoperative markers related to 6-month mortality included: impaired cognition (P < 0.01), recent falls (P < 0.01), lower albumin (P < 0.01), greater anemia (P < 0.01), functional dependence (P < 0.01), and increased comorbidities (P < 0.01). Similar statistical relationships were found for all 6 markers and postdischarge institutionalization. Logistic regression identified any functional dependence (odds ratio 13.9) as the strongest predictor of 6-month mortality. Four or more markers in any one patient predicted 6-month mortality with a sensitivity of 81% (13/16) and specificity of 86% (81/94). CONCLUSIONS: Geriatric assessment markers for frailty, disability and comorbidity predict 6-month postoperative mortality and postdischarge institutionalization. The preoperative presence of > or =4 geriatric-specific markers has high sensitivity and specificity for 6-month mortality. Preoperative assessment using geriatric-specific markers is a substantial paradigm shift from the traditional preoperative evaluation of older adults.
