Social engagement and cognitive impairment among nursing home residents: The role of sensory impairment

BACKGROUND AND OBJECTIVES

Using US national nursing home data, this cross-sectional study sought to evaluate 1) the association between lack of social engagement and level of cognitive impairment; and 2) the extent to which this association differs by hearing and visual impairment.

RESEARCH DESIGN AND METHODS

Our sample included 793,846 nursing home residents aged ≥ 50 years. The Index of Social Engagement was categorized as none/lower (0, 1, 2) or higher levels (3 through 6). Cognitive Performance Scale was grouped as intact/mild (0, 1, 2), moderate (3, 4), or severe (5, 6). Multinomial models provided adjusted odds ratio (aOR) and 95 % confidence intervals (CI) between none/lower social engagement and cognitive impairment. We estimated relative excess risk due to interaction (RERI) to quantify the joint effects of social engagement and sensory impairment types.

RESULTS

Overall, 12.6 % had lower social engagement, 30.3 % had hearing impairment, and 40.3 % had visual impairment. Compared to residents with high social engagement, those with lower social engagement were more likely to have moderate/severe cognitive impairment (aORmoderate = 2.21, 95 % CI 2.17-2.26; aORsevere = 6.49, 95 % CI 6.24-6.74). The impact of low social engagement on cognitive impairment was more profound among residents with hearing impairment and/or visual impairment (RERIhearing = 3.89, 95 % CI 3.62-4.17; RERIvisual = 25.2, 95 % CI 23.9-26.6)).

DISCUSSION AND IMPLICATIONS

Residents with lower social engagement had higher levels of cognitive impairment. Residents with sensory impairments are potentially more susceptible to the negative impact of lower levels of social engagement on level of cognitive impairment.

Antidementia Medication Use in Nursing Home Residents

BACKGROUND

Antidementia medication can provide symptomatic improvements in patients with Alzheimer's disease, but there is a lack of consensus guidance on when to start and stop treatment in the nursing home setting.

METHODS

We describe utilization patterns of cholinesterase inhibitors (ChEI) and memantine for 3,50,197 newly admitted NH residents with dementia between 2011 and 2018.

RESULTS

Overall, pre-admission use of antidementia medications declined from 2011 to 2018 (ChEIs: 44.5% to 36.9%; memantine: 27.4% to 23.2%). Older age, use of a feeding tube, and greater functional dependency were associated with lower odds of ChEI initiation. Coronary artery disease, parenteral nutrition, severe aggressive behaviors, severe cognitive impairment, and high functional dependency were associated with discontinuation of ChEIs. Comparison of clinical factors related to anti-dementia drug treatment changes from pre to post NH admission in 2011 and 2018 revealed a change toward lower likelihood of initiation of treatment among residents with more functional dependency and those with indicators of more complex illness as well as a change toward higher likelihood of discontinuation in residents having 2 or more hospital stays.

CONCLUSIONS

These prescribing trends highlight the need for additional research on the effects of initiating and discontinuing antidementia medications in the NH to provide clear guidance for clinicians when making treatment decisions for individual residents.

Eating Disorder Specialist Views on Gender Competency and Education for Treating Gender Minority Patients

Studies exploring patient experience with eating disorder specialists have reported poor gender competency among clinicians, as revealed through patient-clinician interactions. Through interviews with eating disorder specialists, the authors sought to (1) clarify how and why current practice and clinical training may not meet the needs of transgender and gender-diverse patients, (2) assess where and how clinicians received education on gender identity, and (3) how changes can be made to meet educational and patient needs. Specialists were recruited, and semi-structured interviews were conducted. Narratives were coded by two independent coders, using thematic analysis. Four key themes emerged from 19 completed interviews: Training and education received, importance of receiving training or education, self-education, and improvements recommended by clinicians. Only ~ 16% (n = 3) of clinicians reported sufficient training both in graduate school and through their place of employment. Most with sufficient education received it at their clinic/practice. Despite lacking formal training, all clinicians engaged in some form of self-education on gender. These findings support the need for standardized and comprehensive graduate curricula, in-service training, and continuing education requirements. Advocacy is required to encourage accrediting organizations to mandate training on gender among mental health clinicians.

Social Contact, Social Participation, and Emotional Well-Being Among Older Adults During the COVID-19 Pandemic: The Roles of Giving and Receiving Social Support

This study examined whether social contact, social participation, and social support during the COVID-19 pandemic were associated with depression and anxiety. Data were taken from the 2020 COVID-19 Supplement of the National Health and Aging Trends Study (N = 2,778). Depression and anxiety were regressed on social contact frequency, social participation, and social support. Path analyses were also performed. The results showed that in-person contact was related to lower levels of depression, while in-person contact and attending religious services were related to lower levels of anxiety. Giving and receiving support were associated with higher levels of depression and anxiety. Giving support mediated the link between virtual contact, volunteering, and depression, while receiving support mediated the link between virtual contact and depression. Receiving and giving support mediated the association between virtual social contact, volunteering, and anxiety. During the pandemic, being socially connected provided some benefits in terms of emotional well-being, but in some cases being socially connected did not provide salubrious effects.

Sex Differences in Time to Initiate Nonsteroidal Anti-Inflammatory Drugs or Biologic Disease-Modifying Antirheumatic Drugs Among Patients With Axial Spondyloarthritis

OBJECTIVE

We evaluated sex differences in time to initiation of receiving nonsteroidal anti-inflammatory drugs (NSAIDs) or biologic disease-modifying antirheumatic drugs (bDMARDs) among patients with axial spondyloarthritis (axSpA).

METHODS

Using the 2013 to 2018 IBM MarketScan Database, we identified 174,632 patients with axSpA aged ≥18 years. We evaluated the time between axSpA diagnosis and the first prescription NSAID dispensing (among those with no baseline NSAIDs reception) or bDMARDs infusion/procedure claim (among those who were dispensed two or more different prescription NSAIDs in the baseline period). Adjusted hazard ratios (aHRs) for time to initiation of patients receiving NSAIDs or bDMARDs were computed using survival analyses. Cox proportional hazard models estimated associations between sex and predictors of treatment initiation.

RESULTS

Average age at diagnosis was 48.2 years, 65.7% were female, and 37.8% were dispensed one or more NSAIDs before axSpA diagnosis. Of those who did not receive two or more different prescription NSAIDs before diagnosis, NSAID reception was initiated earlier in female patients than in male patients (NSAID reception initiators: female patients (32.9%), male patients (29.3%); aHR 1.14, 95% confidence interval [CI] 1.11-1.16). Among those who received two or more different prescription NSAIDs in the baseline period, 4.2% received a bDMARD, whereas 77.9% continued receiving NSAIDs after diagnosis. Time to bDMARD reception initiation was longer for female patients than for male patients (aHR 0.61, 95% CI 0.52-0.72), but bDMARDs were received sooner among those who received NSAIDs in the baseline period.

CONCLUSION

Prescription NSAID reception was more common than initiation of receiving bDMARDs among patients newly diagnosed with axSpA. Female patients appeared more likely to continue receiving NSAIDs after diagnosis, and the time to initiation of receiving bDMARDs was longer for female patients than for male patients.

Self- and staff-reported pain in relation to contextual isolation in long-term nursing home residents with Alzheimer's disease and related dementias

We evaluated the degree to which contextual isolation in nursing home residents with Alzheimer's disease and related dementias is associated with documented pain using the Minimum Data Set 3.0, a comprehensive resident assessment required of all nursing home residents in the United States. Contextual isolation was defined as having a socially salient characteristic (demographics, habits and interests, and clinical and care dimensions) shared by fewer than 20% of other residents in the same nursing home. Thirteen percent were contextually isolated on multiple characteristics. Among residents self-reporting pain, residents contextually isolated with respect to multiple characteristics were 8% more likely (95% confidence interval: 7% to 9%) to have pain relative to residents who were not contextually isolated on any characteristics. Long-stay nursing home residents with ADRD who live in settings where they were contextually isolated were more likely to have pain relative to those without contextually isolation on any characteristic.

Changes in Antidementia Medications upon Admission to the Nursing Home: Who Decides and Why? Results From a National Survey of Nursing Home Administrators

OBJECTIVE

Little is known about who is involved and what factors influence changes in antidementia medications for older adults living in nursing homes. The study sought to describe factors associated with initiation and discontinuation of antidementia medications in nursing home residents with dementia.

DESIGN

National survey of nursing homes with ≥30 beds; homes with dementia units were oversampled.

SETTINGS AND PARTICIPANTS

Nursing home administrators [eg, Directors of Nursing (DoNs)].

METHODS

In 2022, 1293 homes were surveyed (response rate: 26.6%, n = 340). Weighted analyses provided nationally representative results corrected for nonresponse (n = 14,455).

RESULTS

DoNs reported that people always/almost always involved in antidementia medication decisions included nursing home prescriber (84.4%), nursing staff (33.2%), family (23.4%), resident (13.8%), community primary care provider (12.1%), and dementia specialist (5.8%). DoNs reported that antidementia medications were much more likely to be initiated if residents (55.8%) and family members (53.2%) wanted antidementia medications, a dementia specialist was involved (51.9%), resident had aggressive behaviors (44.8%), resisted care (31.6%), or had severe physical/cognitive impairment (22.3%). DoNs reported that antidementia medications were much more likely to be discontinued with dementia specialist involvement (46.5%), progression to severe impairment (39.2%), hospice involvement (31.5%), <6 months' prognosis (28.5%), emergence of aggressive behaviors (25.2%), or resisting care (19.0%) and much less likely to be discontinued if residents (30.2%) and family (27.3%) were reluctant to discontinue. One in 6 homes reported that residents had no immediate family/caregivers usually or almost always/always.

CONCLUSIONS AND IMPLICATIONS

DoNs report that family/caregivers and dementia specialists have significant influence on antidementia medication decisions in nursing homes, but many residents lack their involvement. Real-world evidence on the risks and benefits of antidementia medications in nursing homes is needed to inform clinical guidance about appropriate use of antidementia medications in nursing homes.

Association Between Patient and Facility Characteristics and Rehabilitation Outcomes After Joint Replacement Surgery in Different Rehabilitation Settings for Older Adults: A Systematic Review

BACKGROUND AND PURPOSE

In the United States, an exponential increase in total hip arthroplasty (THA) and total knee arthroplasty (TKA) demand has occurred over the last 2 decades. Evidence suggesting patients receiving inpatient rehabilitation following a TKA or THA experience similar outcomes as those with rehabilitation in other settings led to dramatic shifts in postsurgical care settings owing to Centers for Medicare & Medicaid Services (CMS) payment reforms. A contemporary synthesis of evidence about the association between patient and facility factors and outcomes from older adults undergoing THA or TKA in the United States is needed.

METHODS

To identify eligible studies, we searched PubMed, Scopus, and CINAHL. We followed PRISMA guidelines to identify articles evaluating either patient or facility factors associated with outcomes after THA or TKA for older adults who may have been cared for in inpatient settings (ie, inpatient rehabilitation or skilled nursing facility [SNF]). Eligible articles were conducted in the United States and were published between January 1, 2000, and December 31, 2021.

RESULTS

We included 8 articles focused on patient factors and 9 focused on facility factors. Most included older adults and the majority were White (in those reporting race/ethnicity). Most studies evaluated outcomes at discharge and showed that patients admitted to inpatient rehabilitation facilities had either similar or better functional outcomes (mobility, self-care, and functional independence measure (FIM) score) and lower length of stay compared with those in SNFs. Few studies focused on home health care.

CONCLUSIONS

The systematic review focused on older adults showed that findings in these patients are consistent with previous research. Older adults undergoing THA/TKA had acceptable outcomes regardless of postsurgical, inpatient setting of care. Research conducted after CMS payment reforms, in home health care settings, and in more diverse samples is needed. Given the known racial/ethnic disparities in THA/TKA and the shifts to postsurgical home health care with little regulatory oversight of care quality, contemporary research on outcomes of postsurgical THA/TKA outcomes is warranted.

U.S. nursing home leadership experiences with COVID-19 and its impact on residents and staff: A qualitative analysis

OBJECTIVES

To explore experiences of U.S. (United States) nursing home leadership during the COVID-19 pandemic in their efforts to address resident loneliness and social isolation and to elicit stories about personal and professional impacts on themselves and staff.

DESIGN

Qualitative inquiry via three optional open-ended questions appended to a national self-administered survey of American nursing home leaders was employed. Textual data was analyzed using an iterative reflexive thematic approach.

SETTING AND PARTICIPANTS

A stratified sample frame defined by facility size (beds: 30-99, 100+) and quality ratings (1, 2-4, 5) was employed. Web survey links and paper surveys were sent to 1,676 nursing home directors of nursing between February and May 2022.

RESULTS

Open text responses were collected from 271 nursing homes. Broad themes included: 1) Addressing needs of residents & families; 2) Challenges; and 3) Personal experiences of nursing home leadership/staff. Respondents described trauma to residents, staff, and leadership. Resident loneliness was addressed using existing and newer technologies and innovative indoor and outdoor activities. Residents experienced fear, illness, loss, and sometimes death. Isolation from family and lack of touch were particularly difficult. Regulations were seen as punitive while ignoring emotional needs of residents. Staffing challenges and pressures to do more with less created additional stress. Leadership and staff made significant sacrifices resulting in physical, social, and emotional consequences. Beneficial outcomes included staff bonding, professional growth, and permanent implementation of new interventions.

CONCLUSIONS AND IMPLICATIONS

New and creative interventions were successfully implemented to address social isolation and loneliness. Improved Wi-Fi and other nursing home infrastructure upgrades are needed to maintain them. Reimagining often conflicting overlapping federal, state, and local regulations, grounding them in good clinical judgement, and incentivizing performance improvement should be considered. Trauma experienced by staff needs to be addressed to deal with current and future workforce needs.

Frailty, cognitive impairment, and depressive symptoms in Chinese older adults: an eight-year multi-trajectory analysis

BACKGROUND

Frailty, cognitive impairment, and depressive symptoms are closely interrelated conditions in the aging population. However, limited research has longitudinally analyzed the concurrent trajectories of these three prominent conditions in older adults in China. This study aimed to explore the eight-year trajectories of frailty, cognitive impairment, and depressive symptoms, and to identify individual-level and structural-level factors associated with the trajectories.

METHODS

Four waves of data from the China Health and Retirement Longitudinal Study (2011-2018) were used to identify 6,106 eligible older adults. The main measures included frailty by the frailty index constructed using 30 indicators, cognitive impairment by the summary score of immediate and delayed word recall, figure drawing, serial subtraction, and orientation, and depressive symptoms by the Center for Epidemiologic Studies Depression Scale. Multi-trajectory models identified the trajectories of frailty, cognitive impairment, and depressive symptoms over time. Multinomial logistic regression was employed to estimate the associations between individual-level capital factors and one structural factor (hukou and geographic residency) with the identified trajectories, adjusting for demographic characteristics.

RESULTS

Four trajectories emerged: (1) worsening frailty, worsening cognitive impairment, depression (14.0%); (2) declining pre-frailty, declining cognition, borderline depression (20.0%); (3) pre-frailty, worsening cognitive impairment, no depression (29.3%); and (4) physically robust, declining cognition, no depression (36.7%). Using the "physically robust, declining cognition, no depression" as the reference, not working, no social activity participant, worse childhood family financial situation, and poorer adult health were most strongly associated with the "worsening frailty, worsening cognitive impairment, depression" trajectory; worse health during childhood had the highest association with the "declining pre-frailty, declining cognition, borderline depression" trajectory; less education, lower household consumption, and rural hukou had the greatest association with the increased likelihood of the "pre-frailty, worsening cognitive impairment, no depression" trajectory.

CONCLUSIONS

Findings could inform the understanding of the interrelationship of frailty, cognitive impairment, and depressive symptoms in older adults in China and may help practitioners detect adults at risk for adverse trajectories to implement strategies for proper care.

Differences in chronic obstructive pulmonary disease among US nursing home residents with heart failure according to sex and type of heart failure

BACKGROUND

Heart failure and chronic obstructive pulmonary disease (COPD) are leading cause of death throughout the world. Few recent studies have, however, examined possible sex and type of heart failure (HFpEF, HFrEF, and unspecified/other heart failure) differences in the prevalence of these chronic conditions among nursing home residents.

OBJECTIVES

The aim of this study is to examine the magnitude of concomitant COPD and differences according to sex and heart failure type, in terms of the prevalence of COPD among nursing home residents with heart failure.

METHODS

The principal study outcomes were examined in a cross-sectional study of 97 495 US nursing home residents with heart failure using the 2018 Minimum Data Set. The diagnoses of heart failure and COPD were operationalized through a review of nursing home admission, progress notes, and physical examination findings.

RESULTS

The average age of this study population was 81.3 ± 11.0 years, 67.3% were women, and 53.8% had COPD. A slightly higher prevalence of COPD was found among men than women. A higher proportion of unspecified heart failure type was found in both men and women, than reduced and preserved ejection fractions, respectively. In both men and women, there was a higher prevalence of COPD among those with various chronic conditions and current tobacco users.

CONCLUSIONS

COPD is highly prevalent among medically complex middle-aged and older nursing home residents with heart failure. Future research should focus on increasing our understanding of factors that influence the risk and optimal management of COPD and heart failure to improve the quality of life for nursing home residents.

Comparative safety of adding serotonin and norepinephrine reuptake inhibitors (SNRIs) versus nonsteroidal anti-inflammatory drugs (NSAIDs) to short-acting opioids for non-malignant pain in nursing homes

BACKGROUND

The comparative safety of serotonin and norepinephrine reuptake inhibitors (SNRIs) as adjuvants to short-acting opioids in older adults is unknown even though SNRIs are commonly used. We compared the effects of SNRIs versus nonsteroidal anti-Inflammatory drugs (NSAIDs) on delirium among nursing home residents when SNRIs or NSAIDs were added to stable regimens of short-acting opioids.

METHODS

Using 2011-2016 national Minimum Data Set (MDS) 3.0 and Medicare claims data to implement a new-user design, we identified a cohort of nursing home residents receiving short-acting opioids who initiated either an SNRI or an NSAID. Delirium was defined from the Confusion Assessment Method in MDS 3.0 assessments and ICD9/10 codes using Medicare hospitalization claims. Propensity score matching balanced underlying differences for initiating treatments on 39 demographic and clinical characteristics (nSNRIs  = 5350; nNSAIDs  = 5350). Fine and Gray models provided hazard ratios (HRs) and 95% confidence intervals (CIs) adjusting for the competing risk of death.

RESULTS

Hydrocodone was the most commonly used short-acting opioid (48%). Residents received ~23 mg daily oral morphine equivalent at the time of SNRIs/NSAIDs initiation. The majority were women, non-Hispanic White, and aged ≥75 years. There were no differences in any of the confounders after propensity matching. Over 1 year, 10.8% of SNRIs initiators and 8.9% of NSAIDs initiators developed delirium. The rate of delirium onset was similar in SNRIs and NSAID initiators (HR(delirium in nursing home or hospitalization for delirium):1.10; 95% CI: 0.97-1.24; HR(hospitalization for delirium): 1.06; 95% CI: 0.89-1.25), and were similar regardless of baseline opioid daily dosage.

CONCLUSIONS

Among nursing home residents, adding SNRIs to short-acting opioids does not appear to increase risk of delirium relative to initiating NSAIDs. Understanding the comparative safety of pain regimens is needed to inform clinical decisions in a medically complex population often excluded from clinical research.

Postpartum Depression in Reproductive-Age Women With and Without Rheumatic Disease: A Population-Based Matched Cohort Study

OBJECTIVE

To examine postpartum depression (PPD) among women with axial spondyloarthritis (axSpA), psoriatic arthritis (PsA), or rheumatoid arthritis (RA) in comparison with a matched population without rheumatic disease (RD).

METHODS

A retrospective analysis using the 2013-2018 IBM MarketScan Commercial Claims and Encounters Database was conducted. Pregnant women with axSpA, PsA, or RA were identified, and the delivery date was used as the index date. We restricted the sample to women ≤ 55 years with continuous enrollment ≥ 6 months before date of last menstrual period and throughout pregnancy. Each patient was matched with 4 individuals without RD on: (1) maternal age at delivery, (2) prior history of depression, and (3) duration of depression before delivery. Cox frailty proportional hazards models estimated the crude and adjusted hazard ratios (aHR) and 95% CI of incident postpartum depression within 1 year among women with axSpA, PsA, or RA (axSpA/PsA/RA cohort) compared to the matched non-RD comparison group.

RESULTS

Overall, 2667 women with axSpA, PsA, or RA and 10,668 patients without any RD were included. The median follow-up time in days was 256 (IQR 93-366) and 265 (IQR 99-366) for the axSpA/PsA/RA cohort and matched non-RD comparison group, respectively. Development of PPD was more common in the axSpA/PsA/RA cohort relative to the matched non-RD comparison group (axSpA/PsA/RA cohort: 17.2%; matched non-RD comparison group: 12.8%; aHR 1.22, 95% CI 1.09-1.36).

CONCLUSION

Postpartum depression is significantly higher in women of reproductive age with axSpA/PsA/RA when compared to those without RD.

Anxiety and Depression Among US Nursing Home Residents with Chronic Obstructive Pulmonary Disease

Background

Chronic obstructive pulmonary disease (COPD) is highly prevalent among nursing home residents; however, few studies have focused on the psychological impact of this clinically significant condition on nursing home residents.

Objective

We examine the prevalence of, and factors associated with, anxiety and depression in nursing home residents with COPD.

Methods

Using the US 2018 Minimum Dataset (MDS), we conducted a cross-sectional study among 239,615 residents aged ≥50 years old in US Medicare/Medicaid certified nursing homes with COPD. Anxiety and depression were diagnosed based on clinical diagnoses, physical examination findings, and treatment orders. Multivariable adjusted Poisson models with a generalized estimating equations approach account for the clustering among residents within nursing homes.

Results

The average age of the study population was 79 years (SD: 10.6), 62.0% were women, and 43.7% had five or more comorbid conditions. In this population, 37.2% had anxiety, 57.6% had depression, and 27.5% had both mental health conditions. Women, current tobacco users, persons 50-64 years old, those who reported having moderate or severe pain, and nursing home residents with multimorbidity were more likely to have anxiety or depression than respective comparison groups.

Conclusion

Anxiety and depression are common among US nursing home residents with COPD. Women, medically complex patients, and those who report having moderate-to-severe pain appear to be more likely to have anxiety and depression. Clinical teams should be aware of these findings when managing nursing home residents with COPD and use various nonpharmacological and medical interventions for the effective management of anxiety and depression. Longitudinal studies evaluating how anxiety and depression affect the management of COPD and related outcomes, and how best to improve the quality of life of nursing home residents with COPD, are warranted.

Rising to the Occasion: A National Nursing Home Study Documenting Attempts to Address Social Isolation During the COVID-19 Pandemic

OBJECTIVES

COVID-19-related policies introduced extraordinary social disruption in nursing homes. In response, nursing facilities implemented strategies to alleviate their residents' loneliness. This study sought to describe interventions nursing homes used, document the perceived effectiveness of efforts, and determine barriers to implementing strategies to mitigate social isolation and loneliness.

DESIGN

National survey of nursing homes sampled in strata defined by facility size (beds: 30-99, 100+) and quality ratings (1, 2-4, 5).

SETTINGS AND PARTICIPANTS

US Nursing Home Directors of Nursing/Administrators (n = 1676).

METHODS

The survey was conducted between February and May 2022 (response rate: 30%; n = 504, weighted n = 14,506). Weighted analyses provided nationally representative results.

RESULTS

One-third were extremely concerned about their home's ability to meet residents' medical and social needs during COVID-19 before vaccines were available and 13% after vaccines. Nearly all reported trying to mitigate residents' social isolation during the pandemic. Efforts tried, and perceived as most useful, included using technology (tablets, phones, emails), assigning staff as a family contact, and more staff time with residents. Most frequently cited barriers to implementation were related to staffing issues.

CONCLUSIONS AND IMPLICATIONS

Despite multiple challenges, nearly all nursing homes tried to implement many different approaches to address residents' social needs, with some (eg, having an assigned family contact, use of tablets and phones) perceived as more useful than others. Staffing issues presented barriers for addressing the social needs of nursing home residents. Many strategies for addressing social isolation placed more demands on a workforce already stretched to the limit. While concerns about resident social isolation reduced after vaccine availability, administrators remained extremely concerned about staff burnout and mental health.

Pediatrician and Child Adolescent Psychiatrist Perspectives of Coordinated Care for Emerging Adults

PURPOSE

To explore pediatrician and child/adolescent psychiatrists' perspectives of the role of coordinated care for emerging adults with serious mental health conditions, particularly as they transition to adult care.

METHODS

Semi-structured individual interviews of a purposive sample of 10 pediatricians and 11 child/adolescent psychiatrists in Massachusetts were used to explore coordinated care for emerging adults. Following verbatim transcription and double coding, we conducted a thematic analysis to identify key themes. Care coordination concepts explored included a case discussion, teamwork, communication methods, medication management, transition to adult care, the healthcare home, and youth and family role. Organizational and societal barriers were also discussed.

RESULTS

Providers described key barriers to continuous, coordinated care for youth with serious mental health conditions, including poor communication systems between providers, no organized process for the transition from pediatric to adult care, state licensing laws (particularly impacting college-age youth), inadequate connection to community supports, and poor reimbursement rates for psychiatric care. Termination of primary care in young adults and inadequate medication side effect monitoring were described as key gaps in care.

DISCUSSION

The current system of coordinated care for emerging adults with serious mental health conditions is a perfect storm of challenges that creates a vicious cycle of interconnected barriers which lead to fragmented, discontinuous, and sub-par care for this population.

Trends and Factors Associated with Fecal Occult Blood Test Utilization among Hispanic Adults in Puerto Rico and the United States: BRFSS 2012-2020

Identifying factors associated with colorectal cancer screening utilization is important to guide colorectal cancer prevention and control programs. We evaluated trends and factors associated with previous-year fecal occult blood test (FOBT) use among Hispanic adults living in Puerto Rico and the U.S. mainland. Using data from the Behavioral Risk Factor Surveillance System (2012-2020), trends in FOBT use were analyzed using joinpoint regression to estimate annual percentage change (APC). Logistic regression stratified by location identified factors associated with FOBT use. FOBT was more common among Hispanic adults ages 50 to 75 years living in Puerto Rico than in the U.S. mainland [Puerto Rico: 20.5%[2012] to 45.6%[2020], APC = 11.4%; U.S. mainland: 9.9%[2012] to 16.7%[2020], APC = 5.9%]. Factors inversely associated with FOBT use were similar in Puerto Rico and the U.S. mainland, including lack of health insurance, not having a personal doctor, having a checkup >12 months ago, and not being able to see a doctor due to cost, as were factors associated with higher FOBT use, including older age, retirement, or having two or more chronic diseases. Among Hispanics living in the U.S. mainland, lack of exercise and less education were inversely associated with FOBT. Factors related to poor access to healthcare were associated with lower use of FOBT among Hispanics. Efforts to improve colorectal cancer screening in Hispanics are necessary to address health disparities across the colorectal cancer care continuum.

PREVENTION RELEVANCE

Colorectal cancer screening reduces cancer incidence and mortality. All screening modalities, including less invasive FOBT tests, are underutilized, especially in non-White and low-income populations. Evaluation of trends and factors associated with the increase in the use of colorectal cancer screening can inform programs to address the lack of screening among racial minorities.

Provider perceptions of barriers and facilitators to care in eating disorder treatment for transgender and gender diverse patients: a qualitative study

BACKGROUND

The prevalence of eating disorders is higher in transgender and non-binary compared to cisgender people. Gender diverse people who seek eating disorder treatment often report struggling to find affirming and inclusive treatment from healthcare clinicians. We sought to understand eating disorder care clinicians' perceptions of facilitators of and barriers to effective eating disorder treatment for transgender and gender diverse patients.

METHODS

In 2022, nineteen US-based licensed mental health clinicians who specialized in eating disorder treatment participated in semi-structured interviews. We used inductive thematic analysis to identify themes around perceptions and knowledge of facilitators and barriers to care for transgender and gender diverse patients diagnosed with eating disorders.

RESULTS

Two broad themes were identified: (1) factors affecting access to care; and (2) factors affecting care while in treatment. Within the first theme, the following subthemes were found: stigmatization, family support, financial factors, gendered clinics, scarcity of gender-competent care, and religious communities. Within the second theme, prominent subthemes included discrimination and microaggressions, provider lived experience and education, other patients and parents, institutions of higher education, family-centered care, gendered-centered care, and traditional therapeutic techniques.

CONCLUSION

Many barriers and facilitators have potential to be improved upon, especially those caused by clinicians' lack of knowledge or attitudes towards gender minority patients in treatment. Future research is needed to identify how provider-driven barriers manifest and how they can be improved upon to better patient care experiences.

Descriptive Epidemiology of Chronic Obstructive Pulmonary Disease in US Nursing Home Residents With Heart Failure

Chronic obstructive pulmonary disease (COPD) is highly prevalent in older adults with heart failure and heart failure is highly prevalent in older adults with COPD. Information is presently lacking about the extent to which COPD and heart failure co-occur among nursing home residents. The objective of this study was to describe the epidemiology of, and factors associated with, COPD among nursing home residents with heart failure. This cross-sectional study included 97,495 long-term stay nursing home residents with heart failure in 2018. The Minimum Data Set 3.0 (MDS) provided information on sociodemographic characteristics, comorbid conditions, and activities of daily living. Heart failure and COPD were defined based on notes at admission, hospitalizations, progress notes, and through physical examination findings. The majority of the study population were ≥75 years old (74.1%), women (67.3%), and Non-Hispanic Whites (77.4%). Nearly 1 in 5 residents had reduced ejection fraction findings, 23.1% had a preserved ejection fraction, and 53.8% of nursing home residents with heart failure had COPD. This pulmonary condition was less frequently noted in women, residents of advanced age, and racial/ethnic minorities and more frequently diagnosed in residents with comorbid conditions such as pneumonia, anxiety, obesity, diabetes mellitus, and coronary artery disease. We found a high prevalence of COPD, and identified several factors associated with COPD, in nursing home residents with heart failure. Our findings highlight challenges in the clinical management of COPD in nursing home residents with heart failure and how best to meet the care needs of this understudied population.

Unhealed Pressure Ulcers Among Nursing Home Residents with Diabetes

INTRODUCTION

Nearly a third of US nursing home residents have diabetes mellitus. These residents have an increased risk of pressure ulcer (PU) development and progression; however, little is known about the characteristics of their PUs or the role of other risk factors. This study estimates the prevalence of PUs, describes characteristics of PUs, and quantifies associations between risk factors and PUs in nursing home residents with diabetes.

METHODS

We conducted a cross-sectional study of nursing home residents aged ≥50 years with diabetes mellitus using national 2016 Minimum Data Set 3.0 data. Pressure ulcers were defined as the presence of any stage PU and by subgroups of stage and tissue type. Prevalence estimates of PUs were calculated overall and by covariate subgroups. Unadjusted and adjusted odds ratios were calculated using logistic regression.

RESULTS

The prevalence of any unhealed PU was 8.1%. Of those with a PU, 19.4% had at least two ulcers and the most common subtypes were identified as unstageable and stage 2 ulcers. These were most often treated by pressure reducing devices. In our fully adjusted model, risk factors that were strongly associated with PUs were related to mobility, nutrition, incontinence, and infections.

CONCLUSION

We observed that the prevalence of PUs remains high in nursing home residents with diabetes and that higher stage ulcers were common in this population. Our adjusted model highlights the importance of suspected risk factors in the development of PUs. Further research is needed to understand the unique needs of nursing home residents with diabetes.

Physical Frailty and Cognitive Function among Older Chinese Adults: The Mediating Roles of Activities of Daily Living Limitations and Depression

BACKGROUND

Physical frailty and cognitive impairment are prevalent globally, particularly in China, which is experiencing an unprecedented aging of its large population.

OBJECTIVES

Examine the association between physical frailty and the level and rate of change of cognitive function, globally and by domain, among community-dwelling Chinese older adults, and quantify the mediation effects from activities of daily living (ADL) limitations and depressive symptoms.

DESIGN

Longitudinal.

SETTING

China Health and Retirement Longitudinal Study (2011-2018).

PARTICIPANTS

5,431 eligible adults aged ≥ 60 years with valid information on physical frailty.

MEASUREMENTS

Physical frailty, cognitive function, ADL limitations, and depressive symptoms were respectively assessed by frailty phenotypes, the Telephone Interview for Cognitive Status (episodic memory, executive function, and orientation), performance in six daily tasks, and the eight-item Center for Epidemiological Studies Depression Scale. Latent growth curve models were used to address the objectives.

RESULTS

Compared to adults who were non-frail, those who were pre-frail (β = -0.06) and frail (β = -0.13) reported significantly worse global cognitive function and episodic memory (pre-frail: β = -0.05; frail: β = -0.14), executive function (pre-frail: β = -0.04, frail: β = -0.10), and orientation (pre-frail: β = -0.06; frail: β = -0.07) at baseline; those who were frail were more likely to experience faster decline in global cognitive function (β = 0.12) and episodic memory (β = 0.08). ADL limitations (β = -0.07) and depressive symptoms (β = -0.14) significantly mediated the association between physical frailty and the level of cognitive function, but not its rate of decline.

CONCLUSIONS

Intervention strategies that help maintain cognitive function may benefit from early screening and assessment of physical frailty. For pre-frail and frail older Chinese adults, programs designed to help improve or maintain activities of daily living and reduce number of depressive symptoms may contribute to better cognitive performance.

Established Outpatient Care and Follow-Up After Acute Psychiatric Service Use Among Youths and Young Adults

OBJECTIVE

This study explored follow-up after hospitalization and emergency room (ER) use for mental health among youths and young adults with private insurance.

METHODS

The IBM MarketScan commercial database (2013-2018) was used to identify people ages 12-27 with a mental health hospitalization (N=95,153) or ER use (N=108,576). Factors associated with outpatient mental health follow-up within 7 and 30 days of discharge were determined via logistic models with generalized estimating equations that accounted for state variation.

RESULTS

Of those hospitalized, 42.7% received follow-up within 7 days (67.4% within 30 days). Of those with ER use, 28.6% received follow-up within 7 days (46.4% within 30 days). Type of established outpatient care predicted follow-up after hospitalization and ER use. Compared with people with no established care, the likelihood of receiving follow-up within 7 days was highest among those with mental health and primary care (hospitalization, adjusted odds ratio [AOR]=2.81, 95% confidence interval [CI]=2.68-2.94; ER use, AOR=4.06, 95% CI=3.72-4.42), followed by those with mental health care only (hospitalization, AOR=2.57, 95% CI=2.45-2.70; ER use, AOR=3.48, 95% CI=3.17-3.82) and those with primary care only (hospitalization, AOR=1.20, 95% CI=1.15-1.26; ER use, AOR=1.22, 95% CI=1.16-1.28). Similar trends were observed within 30 days of discharge.

CONCLUSIONS

Follow-up rates after acute mental health service use among youths and young adults were suboptimal. Having established mental health care more strongly predicted receiving follow-up than did having established primary care. Improving engagement with outpatient mental health care providers may increase follow-up rates.

Comanagement with rheumatology and prescription biologics filled during pregnancy in women with rheumatic diseases: a retrospective analysis of US administrative claims data

OBJECTIVES

To evaluate comanagement with rheumatology and biological prescriptions filled during pregnancy among women with axial spondyloarthritis (axSpA), rheumatoid arthritis (RA) or psoriatic arthritis (PsA) and to examine factors associated with receiving comanagement with rheumatology during pregnancy.

DESIGN

A retrospective analysis of US claims data.

SETTING

Commercially insured enrollees using data from the 2013-2018 IBM MarketScan Commercial Claims and Encounters Database.

PARTICIPANTS

We identified 4131 pregnant women aged ≤55 years from the 2013-2018 IBM MarketScan Commercial Claims and Encounters Database with an International Classification of Disease, 9th Revision/10th Revision codes for RA, axSpA or PsA, with continuous enrolment at ≥3 months before the date of the last menstrual period (LMP) (index date) and throughout pregnancy.

PRIMARY OUTCOMES

Filled biologics (prescriptions and infusions) claims were categorised by 90 days before the LMP and trimester, as were primary care, obstetrician and rheumatological claims.

RESULTS

The prevalence of axSpA, RA and PsA was 0.7%, 0.2% and 0.04% among reproductive age women. The average maternal age was 32.7 years (SD 5.7). During pregnancy, 9.1% of those with axSpA (n=2,410) and 56.4% of those with RA/PsA (n=1,721) had a rheumatological claim. Biologics claims were less common among those with axSpA (90 days before LMP: 1.6%, during pregnancy: 1.1%) than those with RA/PsA (90 days before LMP: 11.9%, during pregnancy: 6.9%). Medications during pregnancy included corticosteroids (axSpA: 0.3%, RA/PsA: 2.2%), non-biological disease-modifying antirheumatic drugs (axSpA: 0.2%, RA/PsA: 1.7%), non-steroidal anti-inflammatory drugs (axSpA: 0.2%, RA/PsA: 1.3%) and opioids (axSpA: 0.2%, RA/PsA: 0.6%). Established rheumatological care and biologics claims during the 90 days before LMP showed good prediction accuracy for receiving comanagement with rheumatology during pregnancy (axSpA: area under the receiver operator curve (AUC) 0.73, RA/PsA: AUC 0.70).

CONCLUSION

Comanagement with rheumatology during pregnancy occurs infrequently, especially for women with axSpA. Biologics claims during pregnancy may not align with published guidelines. Future research is warranted to improve comanagement with rheumatology during pregnancy.

Health profiles of older nursing home residents by suicidal ideation: A latent class analysis

OBJECTIVES

Identify the health profiles of older nursing home residents with and without at-admission self-reported suicidal ideation (SI) and examine the association between the identified profiles and self-reported SI at 90 days.

METHODS

Using the Minimum Data Set 3.0 and the ninth Patient Health Questionnaire-9 (PHQ-9) item, we identified 15,277 older residents with and 562,184 without self-reported SI at nursing home admission. Latent class analysis, using frailty, cognitive impairment, palliative care index, pain, and remaining PHQ-9 items as indicators, identified health profiles by at-admission SI and the BCH method estimated their association with SI at 90 days.

RESULTS

Profiles identified for residents without at-admission SI were: (1) frail and depressedNoSI (prevalence: 33.9%); (2) frail and severe cognitive impairmentNoSI (38.1%); (3) pre-frailNoSI (28.0%). Residents in the frail and depressedNoSI group had greater odds [adjusted OR: 2.80; 95% Confidence Interval: 2.60-3.00] while those in the frail and severe cognitive impairmentNoSI group had lower odds [aOR: 0.79; 95% CI: 0.71-0.86] of 90-day SI than those in the pre-frailNoSI group. Profiles identified for residents with at-admission SI were: (1) frail and all depressive symptomsSI (22.8%); (2) frail and some depressive symptomsSI (32.2%); (3) frail and severe cognitive impairmentSI (22.9%); (4) pre-frailSI (22.0%). Compared to those in the pre-frailSI group, residents in the frail and all depressive symptomsSI group had greater odds of continuing reporting SI at 90 days [aOR: 1.22; 95% CI:1.09-1.35].

CONCLUSIONS

Findings indicated unique health profiles of nursing home residents at higher risk of new onset of or continued SI.

Social Connectedness among Long-Stay Nursing Home Residents with Alzheimer's and Dementia: Exploring Individual and Facility-Level Variation

INTRODUCTION

This study sought to explore individual and facility-level variation in social connectedness among long-stay nursing home residents with Alzheimer's or other dementias (ADRD).

METHODS

We identified 721,074 long-stay residents with ADRD using 2016 Minimum Data Set 3.0 data. Social connectedness was defined using the social connectedness index (SCI) (high: SCI = 5, lower: 0 < SCI ≤ 4). Adjusted odds ratios (aOR) provided estimates of the associations between resident-level and facility-level characteristics, and high SCI was derived from logistic models.

RESULTS

The SCI Cronbach's alpha was 0.69; 78.6% had high SCI scores. Men were less likely than women to have higher SCI scores (aOR = 0.97; 95% CI: 0.97-0.98). Increasing age was associated with higher SCI scores (e.g., aOR [85-94 vs. 40-64 years]: 1.07; 95% CI: 1.06-1.07). Those with moderate cognitive impairment (aOR: 0.87) and severe cognitive impairment (aOR: 0.85) had reduced odds of SCI = 5 relative to those with mild/intact cognitive function. Residents living in homes with special care dementia units and with higher percentage of residents with dementia had decreased odds of high social connectedness.

DISCUSSION/CONCLUSION

Understanding resident- and nursing home-level variation in social connectedness may be important for targeting interventions that reduce isolation among residents with ADRD.

Multi-trajectory models of serum biomarkers among patients with monoclonal gammopathy of undetermined significance

Understanding the progression of monoclonal gammopathy of undetermined significance (MGUS) to multiple myeloma (MM) is needed to identify patients who would benefit from closer clinical surveillance. Given that two of the defining criteria of MM are renal failure and anemia, we described the trajectories of creatinine (Cr) and hemoglobin (Hgb) over time in patients with a diagnosis of MGUS. Patients diagnosed with MGUS (n = 424) were identified by a previously validated case-finding algorithm using health claims and electronic health record data (2007-2015) and followed through 2018. Group-based trajectory modeling identified patients with distinct laboratory value trajectories of Cr (mg/dl) and Hgb (g/dl). Most patients were non-Hispanic White (97.6%) with a mean age of 75 years at MGUS diagnosis. Three multi-trajectory groups were identified: (1) Normal Cr/Hgb (n = 225; 53.1%)-stable serum Cr levels and decreasing, normal Hgb levels; (2) Normal Cr/lower-normal Hgb group (n = 188; 44.3%)-stable, slightly elevated levels of Cr and decreasing levels of Hgb; and (3) High Cr/borderline Hgb group (n = 11; 2.6%)-increased Cr levels and stable low levels of Hgb. Patients with MGUS in Group 2 were older than patients in other groups, and patients in group 3 had more comorbidities than participants in all other groups. Few patients developed MM during the study period. We were able to identify distinct biomarker trajectories in patients with MGUS over time. Future research should investigate how these trajectories may be related to the risk of progression to MM, including M-protein levels.

Development and test–retest reliability of a screening tool for axial spondyloarthritis

Background

People with axial Spondyloarthritis (axSpA) suffer from lengthy diagnostic delays of ~7 years. The usage of screening tools to identify axSpA patients in primary care can reduce diagnostic delays by facilitating early referral to rheumatologic care. The purpose of this study was to examine the psychometric properties of a potential screening tool for patients with axSpA.

Method

Content validity was evaluated by soliciting feedback from 7 rheumatologists regarding the relevance and content representativeness of the proposed screening questions. For the test-retest study, participants ≥18 years of age with chronic back pain (≥3 months) without a diagnosis of mechanical or inflammatory back pain (n = 91) were e-recruited through ResearchMatch. Participation included completing identical baseline and follow-up questionnaires ~14 days apart. Weighted quadratic kappa was used to measure test-retest reliability between the two ratings of the ordinal scales. Construct validity was examined using exploratory factor analysis (EFA) and items with factor loadings ≥0.6 were extracted. Scale dimensionality and simplified factorial solutions were measured using Kaiser’s criteria (Eigenvalue >1). Cronbach’s alpha was used to measure internal consistency.

Results

Most participants were women, non-Hispanic white, and had at least some college education, with a mean age of 45 years. On average, the age at onset of back pain was 31 years. Eleven questions yielded test–retest reliabilities ranging from 0.6 to 0.76. Results from EFA extracted two factors relating to: 1) how pain affects daily life functioning and 2) whether pain improves with movement. Internal consistency was high for questions evaluating how pain affects life, with a Cronbach’s alpha of 0.81. Following assessment for validity and reliability, the questionnaire was revised to create the 6-item screening tool.

Conclusions

The 6-item SpA-SED screening tool designed to identify potential cases of axSpA was found to have good test–retest reliability and high internal consistency.

Prevalence and treatment of neuropathic pain diagnoses among U.S. nursing home residents

ABSTRACT

Neuropathic pain is a common condition experienced by older adults. Prevalence estimates of neuropathic pain and descriptive data of pharmacologic management among nursing home residents are unavailable. We estimated the prevalence of neuropathic pain diagnoses and described the use of pain medications among nursing home residents with possible neuropathic pain. Using the Minimum Data Set 3.0 linked to Medicare claims for residents living in a nursing home on November 30, 2016, we included 473,815 residents. ICD-10 codes were used to identify neuropathic pain diagnoses. Identification of prescription analgesics/adjuvants was based on claims for the supply of medications that overlapped with the index date over a 3-month look-back period. The prevalence of neuropathic pain was 14.6%. Among those with neuropathic pain, 19.7% had diabetic neuropathy, 27.3% had back and neck pain with neuropathic involvement, and 25.1% had hereditary or idiopathic neuropathy. Among residents with neuropathic pain, 49.9% received anticonvulsants, 28.6% received antidepressants, 19.0% received opioids, and 28.2% had no claims for analgesics or adjuvants. Resident characteristics associated with lack of medications included advanced age, dependency in activities of daily living, cognitive impairment, and diagnoses of comorbid conditions. A diagnosis of neuropathic pain is common among nursing home residents, yet many lack pharmacologic treatment for their pain. Future epidemiologic studies can help develop a more standard approach to identifying and managing neuropathic pain among nursing home residents.

Quality of Nursing Homes Admitting Working-Age Adults With Serious Mental Illness

OBJECTIVE

This cross-sectional study examined the association between nursing home quality and admission of working-age persons (ages 22-64 years) with serious mental illness.

METHODS

The study used 2015 national Minimum Data Set 3.0 and Nursing Home Compare (NHC) data. A logistic mixed-effects model estimated the likelihood (adjusted odds ratios [AORs] and 95% confidence intervals [CIs]) of a working-age nursing home resident having serious mental illness, by NHC health inspection quality rating. The variance partition coefficient (VPC) was calculated to quantify the variation in serious mental illness attributable to nursing home characteristics. Measures included serious mental illness (i.e., schizophrenia, bipolar disorder, and other psychotic disorders), health inspection quality rating (ranging from one star, below average, to five stars, above average), and other sociodemographic and clinical covariates.

RESULTS

Of the 343,783 working-age adults newly admitted to a nursing home in 2015 (N=14,307 facilities), 15.5% had active serious mental illness. The odds of a working-age resident having serious mental illness was lowest among nursing homes of above-average quality, compared with nursing homes of below-average quality (five-star vs. one-star facility, AOR=0.78, 95% CI=0.73-0.84). The calculated VPC from the full model was 0.11.

CONCLUSIONS

These findings indicate an association between below-average nursing homes and admission of working-age persons with serious mental illness, suggesting that persons with serious mental illness may experience inequitable access to nursing homes of above-average quality. Access to alternatives to care, integration of mental health services in the community, and improving mental health care in nursing homes may help address this disparity.

Prevalence of diagnosed eating disorders in US transgender adults and youth in insurance claims

OBJECTIVE

We estimated the prevalence of diagnosed eating disorders, overall and by select demographics, among commercially insured individuals identified as transgender in a national claims database.

METHODS

From the 2018 IBM® MarketScan® Commercial Database, there were 10,415 people identifiable as transgender based on International Classification of Disease (ICD-10) codes and procedure codes, specific to gender-affirming care, from inpatient and outpatient claims. Eating disorders were identified from ICD-10 codes and included anorexia nervosa, bulimia nervosa, binge eating disorder, eating disorder not otherwise specified, avoidant restrictive feeding and intake disorder, and other specified feeding and eating disorders. We estimated the prevalence of specific eating disorders diagnoses by selecting patient characteristics.

RESULTS

Of individuals receiving some form of gender-affirming care, 2.43% (95% confidence interval: 2.14%-2.74%) were diagnosed with an eating disorder: 0.84% anorexia nervosa, 0.36% bulimia nervosa, 0.36% binge eating disorder, 0.15% avoidant restrictive feeding and intake disorder, 0.41% other specified feeding and eating disorders, and 1.37% with an unspecified eating disorder. Among transgender-identifiable patients aged 12-15 years, 5.60% had an eating disorder diagnosis, whereas 0.52% had an eating disorder diagnosis in patients aged 45-64 years.

DISCUSSION

In patients identifiable as transgender, with receipt of gender-affirming care, the prevalence of diagnosed eating disorders was low compared to extant self-reported data for eating disorder diagnosis in transgender individuals. Among this population, eating disorders were highest in adolescents and young adults. Clinically verified prevalence estimates for eating disorder diagnosis in transgender people with a history of gender-affirming care warrant further investigation.

PUBLIC SIGNIFICANCE

The present study aims to provide clinically validated, contemporary prevalence estimates for diagnosed eating disorders among a medically affirmed population of transgender adults and children in the United States. We report low prevalence of having any eating disorder relative to prevalence estimates reported in prior literature without clinical validation. These findings may be explained by access to affirming care and medical care generally.

An algorithm to identify gabapentin misuse and/or abuse in administrative claims data

BACKGROUND

Despite gabapentin's misuse and abuse potential and associated adverse events, few algorithms are available to detect gabapentin misuse and/or abuse in claims data. This study aims to develop an algorithm to identify gabapentin misuse and/or abuse in administrative claims data.

METHODS

We developed an algorithm to identify gabapentin misuse and/or abuse over a 12-month period based on input from 21 clinical experts. We implemented the algorithm among 334,128 patients with at least one dispensed prescription of gabapentin between December 1, 2017 and December 1, 2018 in the IBM® MarketScan® Research Databases. We described the characteristics of patients who potentially misused and/or abused gabapentin and assessed factors associated with misuse and/or abuse using logistic regression.

RESULTS

The algorithm identified 17.6% of patients with gabapentin use who potentially misused and/or abused gabapentin. Factors associated with potential gabapentin misuse and/or abuse included men (adjusted odds ratio (aOR): 1.08; 95% confidence interval (CI): 1.06-1.10), comorbid conditions (e.g., drug and alcohol dependence (aOR: 1.31; 95% CI: 1.24-1.39); bipolar disorder (aOR: 1.34; 95% CI: 1.27-1.41)), and medication use (e.g., opioids (aOR: 1.23; 95% CI: 1.20-1.26), muscle relaxants (aOR: 1.24; 95% CI: 1.21-1.27), or serotonin-norepinephrine reuptake inhibitors (aOR: 1.33; 95% CI: 1.29-1.36)).

CONCLUSIONS

Approximately one in six patients with gabapentin use potentially misused and/or abused gabapentin in a large commercial claims database. Multiple comorbidities and drug use were associated with gabapentin misuse and/or abuse. Monitoring requirements and individualized safety measures should be put in place for patients at elevated risks of gabapentin misuse and/or abuse.

Antihyperglycemic Drug Use in Long-Stay Nursing Home Residents with Diabetes Mellitus

BACKGROUND

About 29.2% of American adults ≥ 65 years of age have diabetes mellitus, but details regarding diabetes management especially among nursing home residents are dated.

OBJECTIVES

Evaluate the prevalence of antihyperglycemic agents in residents with diabetes mellitus and describe resident characteristics using major drug classes.

DESIGN

cross-sectional study.

SETTING

virtually all United States nursing homes.

PARTICIPANTS

141,636 residents with diabetes mellitus.

MEASUREMENTS

Minimum Data Set (2016) and Medicare Part D claims determined use of metformin, sulfonylureas, meglitinide analogs, alpha-glucosidase inhibitors, TZDs, DPP4 inhibitors, SGLT2 inhibitors, GLP1 agonists, as monotherapy and with basal insulin.

RESULTS

Seventy-two percent received antihyperglycemic drugs [most common: basal insulins (53.9% total; 46.9% with other non-insulin agents), metformin (35.5% total; 14.2% monotherapy), sulfonylureas (19.6% total; 6.3% monotherapy), and DPP4 inhibitors (12.2% total; 2.2% monotherapy)]. Sixty-three percent of meglitinide monotherapy versus 34.1% of metformin monotherapy users; and 38.3% meglitinide-basal insulin versus 22.2% metformin-basal insulin users were ≥85 years. Obesity was greater among users of GLP1 agonists compared to those receiving other agents (monotherapy: 60.5% versus 33-42%; with basal insulin: 76.2% versus 50-58%). End-stage renal disease was least prevalent among metformin users (monotherapy: 6.6%; with basal insulin: 8.8%) and most common among meglitinide monotherapy (19.6%) and GLP1 agonists with basal insulin (22%) users.

CONCLUSIONS

There is heterogeneity of diabetes treatment in nursing homes. Use of antihyperglycemic drugs with a higher risk of hypoglycemia, such as insulin with sulfonylureas or meglitinides, continue in nursing home residents.

Cumulative exposure to state-level structural sexism and risk of disordered eating: Results from a 20-year prospective cohort study

BACKGROUND

Gendered inequities in disordered eating are well-documented, yet few studies have examined their structural drivers. To help fill this gap, we investigated whether cumulative exposure to state-level structural sexism from childhood through young adulthood potentiates differences in disordered eating risk between cisgender girls/women and boys/men.

METHODS

Participants came from the Growing Up Today Study (N = 16,875), a cohort of children aged 9-14 years in 1996 who we followed through 2016. Using a composite index of relevant state policies and social inequalities from the Institute for Women's Policy Research, we categorized states as having high or low levels of structural sexism and summed the number of years participants had lived in a high structural sexism state during the study period to quantify their cumulative exposure. We fit sequential conditional mean models to estimate the effect of cumulative exposure on risk of four outcomes (chronic dieting, purging, binge eating, and overeating), controlling for individual- and state-level confounders via propensity scores. We then tested whether effects differed between girls/women and boys/men by including cumulative-exposure-by-gender-identity interaction terms and calculating the relative excess risk due to interaction (RERI).

RESULTS

In the full sample, each additional year of living in a high structural sexism state was associated with a 5% increased risk of purging (95% confidence interval (CI): 3%, 7%), an 8% increased risk of binge eating (95% CI: 6%, 10%), and a 9% increased risk of overeating (95% CI: 8%, 11%). Risk increases were larger on average for girls/women than for boys/men, and girls/women who had lived in a high structural sexism state for four or more years had excess risk of chronic dieting (RERI: 0.64, 95% CI: 0.18, 1.10), purging (RERI: 2.64, 95% CI: 1.24, 4.30), and binge eating (RERI: 2.21, 95% CI: 0.93, 3.50).

CONCLUSIONS

Structural sexism may contribute to inequities in disordered eating between cisgender girls/women and boys/men. Future research should include transgender and gender diverse participants, explore intersectional effects, and identify underlying mechanisms to inform policy-oriented interventions.

Association Between Body Mass Index and Cancer Screening Adherence Among Latinas in the United States and Puerto Rico

Background

Research on the role of body size on cancer screening is mixed with few studies among Latinas in the United States. We evaluated the association between body size and cancer screening adherence among Latinas living in Puerto Rico and the rest of the United States.

Methods

We conducted a cross-sectional study using 2012-2018 Behavioral Risk Factor Surveillance System data among Latinas 50-64 years of age (n = 16,410). Breast, cervical, and colorectal cancer screening (guideline adherent: yes/no), height and weight were self-reported. Prevalence ratios (PRs) derived from Poisson models were estimated for each cancer screening utilization for Puerto Rico versus rest of the United States by body mass index (BMI) category.

Results

Nearly a quarter of women lacked adherence with breast and cervical cancer screening and 43.6% were nonadherent to colorectal cancer screening. Latinas with BMI ≥40.0 kg/m² in both groups were more likely to lack adherence to cervical cancer screening than women with BMI 18.5-24.9 kg/m². For those with BMI ≥40.0 kg/m², Latinas in Puerto Rico were more likely to lack adherence to colorectal cancer screening recommendations than Latinas living in the rest of the United States (adjusted PR: 1.38; 95% confidence interval = 1.12-1.70).

Conclusions

The role of body size in cancer screening utilization among Latinas differs in women living in Puerto Rico versus in the rest of the United States and varies by cancer type. Understanding Latinas' experience can inform culturally adapted interventions to promote cancer screening.

Trajectories of physical frailty and cognitive impairment in older adults in United States nursing homes

Background

U.S. nursing homes provide long-term care to over 1.2 million older adults, 60% of whom were physically frail and 68% had moderate or severe cognitive impairment. Limited research has examined the longitudinal experience of these two conditions in older nursing home residents.

Methods

This national longitudinal study included newly-admitted non-skilled nursing care older residents who had Minimum Data Set (MDS) 3.0 (2014–16) assessments at admission, 3 months, and 6 months (n = 266,001). Physical frailty was measured by FRAIL-NH and cognitive impairment by the Brief Interview for Mental Status. Separate sets of group-based trajectory models were fitted to identify the trajectories of physical frailty and trajectories of cognitive impairment, and to estimate the association between older residents’ characteristics at admission with each set of trajectories. A dual trajectory model was used to quantify the association between the physical frailty trajectories and cognitive impairment trajectories.

Results

Over the course of the first six months post-admission, five physical frailty trajectories [“Consistently Frail” (prevalence: 53.0%), “Consistently Pre-frail” (29.0%), “Worsening Frailty” (7.6%), “Improving Frailty” (5.5%), and “Consistently Robust” (4.8%)] and three cognitive impairment trajectories [“Consistently Severe Cognitive Impairment” (35.5%), “Consistently Moderate Cognitive Impairment” (31.8%), “Consistently Intact/Mild Cognitive Impairment” (32.7%)] were identified. One in five older residents simultaneously followed the trajectories of “Consistently Frail” and “Consistently Severe Cognitive Impairment”. Characteristics associated with higher odds of the “Improving Frailty”, “Worsening Frailty”, “Consistently Pre-frail” and “Consistently Frail” trajectories included greater at-admission cognitive impairment, age ≥ 85 years, admitted from acute hospitals, cardiovascular/metabolic diagnoses, neurological diagnoses, hip or other fractures, and presence of pain. Characteristics associated with higher odds of the “Consistently Moderate Cognitive Impairment” and “Consistently Severe Cognitive Impairment” included worse at-admission physical frailty, neurological diagnoses, hip fracture, and receipt of antipsychotics.

Conclusions

Findings provided information regarding the trajectories of physical frailty, the trajectories of cognitive impairment, the association between the two sets of trajectories, and their association with residents’ characteristics in older adults’ first six months post-admission to U.S. nursing homes. Understanding the trajectory that the residents would most likely follow may provide information to develop a comprehensive care approach tailored to their specific healthcare goals.

Heart failure among US nursing home residents with diabetes mellitus

BACKGROUND

Type 2 diabetes mellitus is associated with an increased risk of developing heart failure. However, few recent studies have examined the characteristics of older adults living in US nursing homes with heart failure and diabetes mellitus. This study is important for clinical practice and public health action plans for heart failure.

OBJECTIVE

To estimate the prevalence of, and factors associated with, heart failure in long-stay nursing home residents with diabetes mellitus.

METHODS

We conducted a cross-sectional study using the US 2016 Minimum Data Set data consisting of all residents with diabetes aged ≥65 years in Medicare/Medicaid certified nursing homes (n = 297,570). Diabetes mellitus and heart failure were operationalized using the resident's transfer notes at admission and the progress notes during admission through physical examination findings and current treatment orders.

RESULTS

Among all residents with diabetes, 26.4% had heart failure. Increasing age of residents, and comorbidities including coronary artery disease (aOR: 1.34; 95% CI: 1.31-1.37), end stage renal disease (aOR: 1.30; 95% CI: 1.26-1.35), and chronic obstructive pulmonary disease (aOR: 1.60; 95% CI: 1.57-1.63) were associated with a higher odds of heart failure.

CONCLUSIONS

This is one of the first U.S studies to examine the prevalence and factors associated with heart failure in nursing home residents with diabetes mellitus. It highlights a clinically complex population with multiple comorbid conditions. Future research is needed to understand the pharmacological management of these residents and the extent to which appropriate management can improve quality of life for a medically vulnerable population.

Geographic Variation in the Use of Gabapentinoids and Opioids for Pain in a Commercially Insured Adult Population in the United States

Background

Gabapentinoids have been prescribed off-label for almost all types of pain. The geographic variation in the use of gabapentinoids as analgesics remains unknown.

Objective

To describe the geographic variation in gabapentinoids, opioids and concurrent use of both for pain by US state and metropolitan statistical area (MSA).

Methods

We conducted a cross-sectional study on December 1, 2018, among commercially insured adults aged 18–64 years without epilepsy or opioid use disorders using IBM^® MarketScan^® Research Databases. We described the geographic variation in the analgesic regimens (gabapentinoids, opioids and concurrent use of both) by state and MSA, and assessed factors associated with the geographic variation using multilevel logistic regression.

Results

We included 9,314,197 beneficiaries; 1.4% had gabapentinoids, 1.5% had opioids and 0.3% had concurrent use of both. The majority of gabapentinoid use lacked an FDA-approved indication. Use of the analgesic regimens varied across states (gabapentinoids (median (interquartile range)): 1.4% (1.2–1.7%); opioids: 1.5% (1.2–1.9%); both: 0.3% (0.2–0.4%)) and MSAs (gabapentinoids: 1.6% (1.3–2.0%); opioids: 1.8% (1.3–2.3%); both: 0.3% (0.2–0.5%)). Demographics explained the largest proportion of the between-state and between-MSA variation. The pattern of the geographic variation in gabapentinoids was similar to that of opioids across states and MSAs.

Conclusion

Gabapentinoids were as commonly used as opioids for pain in a commercially insured population (mostly off-label). The geographic variation in gabapentinoids was similar to that of opioids, which suggests that gabapentinoids may be widely used as alternatives or adjuvants to opioids across the US.

Differences in Hospital, Emergency Room and Outpatient Visits Among Adults With and Without Monoclonal Gammopathy of Undetermined Significance

INTRODUCTION

This study evaluated the impact of receiving a monoclonal gammopathy of undetermined significance (MGUS) diagnosis on healthcare utilization from patients at a community-based multispecialty provider organization.

METHODS

A cohort of patients with MGUS (n = 429) were matched on sex, age, and length of enrollment to a cohort of patients without MGUS (n = 1286). Healthcare utilization was assessed: 1-12 months before, 1 month before and after, and 1-12 months after diagnosis/index date. Multivariable conditional Poisson models compared change in utilization of each service in patients with and without MGUS.

RESULTS

During the 2 months around diagnosis/index date, the rates of emergency room, hospital and outpatient visits were higher for patients with MGUS than patients without MGUS. In the year before MGUS diagnosis, the association was still elevated, although attenuated.

CONCLUSION

Understanding the care of MGUS patients is important given that multiple myeloma patients with a pre-existing MGUS diagnosis may have a better prognosis.

Patient perspectives on health care provider practices leading to an axial spondyloarthritis diagnosis: an exploratory qualitative research study

BACKGROUND

The average time to a diagnosis for people with axial spondyloarthritis (axSpA) is 7-10 years. Delayed diagnosis may result in increased structural damage, worse physical function, and worse quality of life relative to patients with a timely axSpA diagnosis. Understanding patient experiences may provide insights for how to reduce diagnostic delays.

OBJECTIVE

To provide foundational knowledge about patient experiences with healthcare providers leading to an axSpA diagnosis.

METHODS

We conducted an exploratory qualitative research study with six focus groups interviews with participants recruited from three rheumatology clinics within the United States (MA (n = 3); CO (n = 2); PA (n = 1)) that included a total of 26 adults (10 females, 16 males) with rheumatologist confirmed diagnosis of axSpA in 2019. Focus groups were ~ 2 h, audio recorded, transcribed, and subject to dual coding. The codes reviewed were in relation to the patients' diagnostic experiences.

RESULTS

Patients described frustrating and lengthy diagnostic journeys. They recognized that the causes of diagnostic delays in axSpA are multifactorial (e.g., no definitive diagnostic test, disease characteristics, lack of primary care provider's awareness about axSpA, trust). Patients described how doctors minimized or dismissed complaints about symptoms or told them that their issues were psychosomatic. Patients believed the healthcare system contributed to diagnostic delays (e.g., lack of time in clinical visits, difficulty accessing rheumatologists, health insurance challenges). Advice to physicians to reduce the diagnostic delay included allowing time for patients to give a complete picture of their illness experience, listening to, and believing patients, earlier referral to rheumatology, provision of HLA-B27 gene testing, and that physicians need to partner with their patients.

CONCLUSIONS

Patients desire a definitive test that could be administered earlier in the course of axSpA. Until such a test is available, patients want clinicians who listen to, believe, and partner with them, and who will follow them until a diagnosis is reached. Educating primary care clinicians about guidelines and referral for diagnosis of axSpA could reduce diagnostic delay.

Characteristics of Working-Age Adults With Schizophrenia Newly Admitted to Nursing Homes

OBJECTIVES

Persons aged <65 years account for a considerable proportion of US nursing home residents with schizophrenia. Because they are often excluded from psychiatric and long-term care studies, a contemporary understanding of the characteristics and management of working-age adults (22-64 years old) with schizophrenia living in nursing homes is lacking. This study describes characteristics of working-age adults with schizophrenia admitted to US nursing homes in 2015 and examines variations in these characteristics by age and admission location. Factors associated with length of stay and discharge destination were also explored.

DESIGN

This is a cross-sectional study using the Minimum Data Set 3.0 merged to Nursing Home Compare.

SETTING AND PARTICIPANTS

This study examines working-age (22-64 years) adults with schizophrenia at admission to a nursing home.

METHODS

Descriptive statistics of resident characteristics (sociodemographic, clinical comorbidities, functional status, and treatments) and facility characteristics (ownership, geography, size, and star ratings) were examined overall, stratified by age and by admission location. Generalized estimating equation models were used to explore the associations of age, discharge to the community, and length of stay with relevant resident and facility characteristics. Coefficient estimates, adjusted odds ratios, and 95% CIs are presented.

RESULTS

Overall, many of the 28,330 working-age adults with schizophrenia had hypertension, diabetes, and obesity. Those in older age subcategories tended to have physical functional dependencies, cognitive impairments, and clinical comorbidities. Those in younger age subcategories tended to exhibit higher risk of psychiatric symptoms.

CONCLUSIONS AND IMPLICATIONS

Nursing home admission is likely inappropriate for many nursing home residents with schizophrenia aged <65 years, especially those in younger age categories. Future psychiatric and long-term care research should include these residents to better understand the role of nursing homes in their care and should explore facility-level characteristics that may impact quality of care.

Risk factors associated with suicidal ideation in newly admitted working-age nursing home residents

INTRODUCTION

Suicide is a leading cause of mortality in the United States and recent initiatives have sought to increase monitoring of suicide risk within healthcare systems. Working-age adults (22-64 years) admitted to nursing homes may be at risk for suicidal ideation, yet little is known about this population.

METHODS

The national nursing home database, Minimum Dataset 3.0, was used to identify 323,436 working-age adults newly admitted to a nursing home in 2015. This cross-sectional study sought to describe sociodemographic and clinical characteristics, examine behavioral health treatment received, and determine resident characteristics associated with suicidal ideation at nursing home admission using logistic regression and reports adjusted odds ratios (aOR).

RESULTS

Suicidal ideation was present among 1.27% of newly admitted working-age residents. Almost 25% of those with suicidal ideation had no psychiatric diagnosis. Factors associated with increased odds of suicidal ideation included younger age (aOR 1.90), admission from the community (aOR 1.92) or a psychiatric hospital (aOR 2.38), cognitive impairments (aOR 1.46), pain (aOR 1.40), rejection of care (aOR 1.91), and psychiatric comorbidity (aOR depression: 1.91, anxiety disorder: 1.11, bipolar disorder: 1.62, schizophrenia: 1.32, post-traumatic stress disorder: 1.17).

LIMITATIONS

Due to the cross-sectional nature of this study, no causal inferences about suicidal ideation and the explored covariates can be made. The Minimum Dataset 3.0 has only one measure of suicidal ideation the Patient Health Questionnaire.

CONCLUSION

Factors other than psychiatric diagnosis may be important in identifying newly admitted working-age nursing home residents who require on-going suicide screening and specialized psychiatric care.

Changes in depressive symptoms and cognitive impairment in older long-stay nursing home residents in the USA: a latent transition analysis

OBJECTIVES

To longitudinally examine the latent statuses of depressive symptoms and their association with cognitive impairment in older U.S. nursing home (NH) residents.

METHOD

Using Minimum Data Set 3.0, newly-admitted, long-stay, older NH residents with depression in 2014 were identified (n = 88,532). Depressive symptoms (Patient Health Questionnaire-9) and cognitive impairment (Brief Interview of Mental Status) were measured at admission and 90 days. Latent transition analysis was used to examine the prevalence of and the transition between latent statuses of depressive symptoms from admission to 90 days, and the association of cognitive impairment with the statuses at admission.

RESULTS

Four latent statuses of depressive symptoms were identified: 'Multiple Symptoms' (prevalence at admission: 17.3%; 90 days: 13.6%), 'Depressed mood' (20.0%; 19.5%), 'Fatigue' (27.4%; 25.7%), and 'Minimal Symptoms' (35.3%; 41.2%). Most residents remained in the same status from admission to 90 days. Compared to residents who were cognitively intact, those with moderate impairment were more likely to be in 'Multiple Symptoms' and 'Fatigue' statuses; those with severe impairment had lower odds of belonging to 'Multiple Symptoms', 'Depressed Mood', and 'Fatigue' statuses.

CONCLUSION

By addressing the longitudinal changes in the heterogeneous depressive symptoms and the role of cognitive impairment, findings have implications for depression management in older NH residents.

Physical frailty and cognitive impairment in older nursing home residents: a latent class analysis

BACKGROUND

Little is known about the heterogeneous clinical profile of physical frailty and its association with cognitive impairment in older U.S. nursing home (NH) residents.

METHODS

Minimum Data Set 3.0 at admission was used to identify older adults newly-admitted to nursing homes with life expectancy ≥6 months and length of stay ≥100 days (n = 871,801). Latent class analysis was used to identify physical frailty subgroups, using FRAIL-NH items as indicators. The association between the identified physical frailty subgroups and cognitive impairment (measured by Brief Interview for Mental Status/Cognitive Performance Scale: none/mild; moderate; severe), adjusting for demographic and clinical characteristics, was estimated by multinomial logistic regression and presented in adjusted odds ratios (aOR) and 95% confidence intervals (CIs).

RESULTS

In older nursing home residents at admission, three physical frailty subgroups were identified: "mild physical frailty" (prevalence: 7.6%), "moderate physical frailty" (44.5%) and "severe physical frailty" (47.9%). Those in "moderate physical frailty" or "severe physical frailty" had high probabilities of needing assistance in transferring between locations and inability to walk in a room. Residents in "severe physical frailty" also had greater probability of bowel incontinence. Compared to those with none/mild cognitive impairment, older residents with moderate or severe impairment had slightly higher odds of belonging to "moderate physical frailty" [aOR (95%CI)moderate cognitive impairment: 1.01 (0.99-1.03); aOR (95%CI)severe cognitive impairment: 1.03 (1.01-1.05)] and much higher odds to the "severe physical frailty" subgroup [aOR (95%CI)moderate cognitive impairment: 2.41 (2.35-2.47); aOR (95%CI)severe cognitive impairment: 5.74 (5.58-5.90)].

CONCLUSIONS

Findings indicate the heterogeneous presentations of physical frailty in older nursing home residents and additional evidence on the interrelationship between physical frailty and cognitive impairment.

A Latent Approach to Understanding Pain in Nursing Home Residents Who are Unable to Self-Report Pain

Context

Pain assessment in people with cognitive impairment is challenging.

Objective

The study sought to 1) identify pain subgroups based on staff-assessed pain, agitated and reactive behavior, functional status, and symptoms of depression; and 2) understand if cognitive impairment was associated with transitions between pain subgroups at nursing home admission, 3 months, and 6 months.

Methods

Using national Minimum Data Set 3.0 data (2011–2016), we included 26,816 newly admitted residents with staff-assessed pain at admission, 3 months, and 6 months. Pain subgroups were identified by latent class analysis at each time point. Transitions between pain subgroups were described using latent transition analysis.

Results

Five latent statuses of pain were identified at admission: “Behavioral and Severe Depression” (prevalence stable, severe or worsening cognitive impairment: 11%, mild/moderate or improved cognitive impairment: 10%), “Functional” (21%; 25%), “Physical” (22%; 23%), “Behavioral” (23%, 19%), and “Low” (23%; 24%). Regardless of change in cognitive status, most residents remained in the same pain latent class. Among residents with stable, severe or worsening cognitive impairment, 11% in the “Behavioral” class transitioned to the “Behavioral and Severe Depression” class by 3 months. Fewer residents transitioned between latent classes in the 3- to 6-month period (>80% remained in their 3-month class).

Conclusion

For nursing home residents unable to self-report pain, consideration of additional indicators including functioning, depressive symptoms, and agitation may be useful in identifying pain subgroups. Longitudinal changes in the pain subgroups over 6 months post-admission highlight that residents with severe cognitive impairment may be at risk for worsening pain.

Development and psychometric evaluation of the Social Connectedness Index in nursing home residents with Alzheimer's disease and dementia using the Minimum Data Set 3.0

OBJECTIVES

To develop a reliable and valid measure of social connectedness among nursing home residents with Alzheimer's disease and related dementias (ADRD) using items available in the Minimum Dataset 3.0 (MDS).

METHODS

We conducted a retrospective scale development study using the 2016 MDS with two populations of nursing home residents with ADRD: (1) new admissions (not post-acute care) (n = 146,694); (2) residents with comprehensive annual assessments (n = 294,704). Twenty-nine items were included for consideration. Psychometric evaluation included content validity, item analysis, internal consistency reliability, criterion-related validity, and exploratory factor analysis. Analyses were stratified by self- or staff-assessed pain.

RESULTS

The resulting five item Social Connectedness Index (SCI) has good content (Fleiss Kappa = 0.67), criterion-related and construct validity and adequate internal consistency reliability (Kuder Richardson-20: 0.63-0.74) in persons with ADRD. As anticipated, younger residents, men, and those with severe cognitive impairment, anxiety, and depression were more likely to be categorized in the low social connectedness group.

CONCLUSION

The SCI is a promising measure for estimating the amount of social connectedness present for nursing home residents with ADRD. Further work needs to be done to evaluate the usefulness of the SCI for evaluating health and well-being among this population over time.

Abstract 895: Multi-trajectory models of multiple myeloma progression among patients with monoclonal gammopathy of undetermined significance

Background: Understanding the progression of monoclonal gammopathy of undetermined significance (MGUS) to multiple myeloma is needed to identify patients who would benefit from closer clinical surveillance. Given that two of the defining criteria of multiple myeloma are renal failure and anemia, we described the trajectories of creatinine and hemoglobin over time in patients with a diagnosis of MGUS.

Methods: We analyzed data from 429 patients who were diagnosed with MGUS at a large provider group in central Massachusetts between 2007 and 2015 and were followed up through 2018. Patients diagnosed with MGUS were identified by a previously validated case-finding algorithm using health claims and electronic health record data. Group-based trajectory modeling was used to identify groups of patients with distinct laboratory value trajectories of creatinine (mg/dL) and hemoglobin (mg/dL).

Results: The study sample was mostly non-Hispanic white (85.1%) with a mean age of 75 years at MGUS diagnosis. Three multi-trajectory groups were identified. Patients in Group 1 (54.3%) and Group 2 (43.1%) had increasing serum levels of creatinine and decreasing levels of hemoglobin over time, with group 2 having higher increments. Group 3 (2.6%) patients had increasing levels of creatinine and stable low levels of hemoglobin. Patients with MGUS in group 2 were older, less likely to have a prior cancer diagnosis, and had fewer comorbidities than other groups. Twenty-one patients (4.9%) developed multiple myeloma during the study period, with incidence proportions of 0.5%, 1.5%, and 1.6%, respectively for patients in groups 1, 2, and 3.

Conclusion: The data suggest that certain subpopulations of patients with MGUS can be characterized by biomarker trajectories over time. Future research should further investigate how these trajectories may be related to risk of progression to multiple myeloma.

Eating-related pathology at the intersection of gender identity and expression, sexual orientation, and weight status: An intersectional Multilevel Analysis of Individual Heterogeneity and Discriminatory Accuracy (MAIHDA) of the Growing Up Today Study cohorts

The objective of this study was to investigate how gender identity, the overwhelmingly prioritized dimension of social identity/position in eating-related pathology research, intersects with gender expression, sexual orientation, and weight status to structure the social patterning of eating disorders and disordered eating behaviors among young people in the U.S. Data were drawn from the 2010/2011 Growing Up Today Study (GUTS; N = 11,090-13,307). We conducted an intersectional Multilevel Analysis of Individual Heterogeneity and Discriminatory Accuracy (MAIHDA) by nesting participants within social strata defined by intersecting gender identity, gender expression, sexual orientation, and weight status categories in a series of multilevel logistic models for four outcomes (past-year purging, overeating, and binge eating; lifetime eating disorder diagnosis). To illustrate the advantages of intersectional MAIHDA, we compared the results to those from unitary and conventional intersectional analyses. The intersectional MAIHDA revealed a complex social patterning of eating-related pathology characterized by heterogeneity and outcome-specificity. Several multiply marginalized strata (e.g., those including gender nonconforming, sexual minority, and/or larger-bodied girls/women) had disproportionately elevated prevalence, although all estimates were driven by additive effects. Notably, these patterns were obscured within the unitary and conventional intersectional analyses. Future epidemiologic research on eating-related pathology should continue to adopt an intersectional approach through the use of appropriate methodologies.

Geographic Variation in Anticoagulant Use and Resident, Nursing Home, and County Characteristics Associated With Treatment Among US Nursing Home Residents

OBJECTIVES

To quantify geographic variation in anticoagulant use and explore what resident, nursing home, and county characteristics were associated with anticoagulant use in a clinically complex population.

DESIGN

A repeated cross-sectional design was used to estimate current oral anticoagulant use on December 31, 2014, 2015, and 2016.

SETTING AND PARTICIPANTS

Secondary data for United States nursing home residents during the period 2014-2016 were drawn from the Minimum Data Set 3.0 and Medicare Parts A and D. Nursing home residents (≥65 years) with a diagnosis of atrial fibrillation and ≥6 months of Medicare fee-for-service enrollment were eligible for inclusion. Residents in a coma or on hospice were excluded.

METHODS

Multilevel logistic models evaluated the extent to which variation in anticoagulant use between counties could be explained by resident, nursing home, and county characteristics and state of residence. Proportional changes in cluster variation (PCVs), intraclass correlation coefficients (ICCs), and adjusted odds ratios (aORs) were estimated.

RESULTS

Among 86,736 nursing home residents from 11,860 nursing homes and 1694 counties, 45% used oral anticoagulants. The odds of oral anticoagulant use were 18% higher in 2016 than 2014 (aOR: 1.18; 95% confidence interval: 1.14-1.22). Most states had counties in the highest (51.3-58.9%) and lowest (31.1%-41.4%) deciles of anticoagulant use. Compared with the null model, adjustment for resident characteristics explained one-third of the variation between counties (PCV: 34.8%). The full model explained 65.5% of between-county variation. Within-county correlation was a small proportion (ICC < 2.2%) of total variation.

CONCLUSIONS AND IMPLICATIONS

In this older adult population at high risk for ischemic stroke, less than half of the residents received treatment with anticoagulants. Variation in treatment across counties was partially attributable to the characteristics of residents, nursing homes, and counties. Comparative evidence and refinement of predictive algorithms specific to the nursing home setting may be warranted.
