Evaluation of Dynamic Effects of Depressive Symptoms on Physical Function in Knee Osteoarthritis.

OBJECTIVE: To assess how changes in depressive symptoms influence physical function over time among those with radiographic knee osteoarthritis (OA). METHODS: Participants from the Osteoarthritis Initiative with radiographic knee OA (n = 2,212) and complete data were identified at baseline. Depressive symptoms were assessed as a time-varying score at baseline and the first three annual follow-up visits using the Center for Epidemiological Studies Depression Scale (CES-D) Scale. Physical function was measured at the first four follow-up visits using 20-meter gait speed meters per second. The following two marginal structural models were fit: one assessing the main effect of depressive symptoms on gait speed and another assessing time-specific associations. RESULTS: Time-adjusted results indicated that higher CES-D scores were significantly associated with slower gait speed (-0.0048; 95% confidence interval -0.0082 to -0.0014), and time-specific associations of CES-D were largest during the first follow-up interval (-0.0082; 95% confidence interval -0.0128 to -0.0035). During subsequent follow-up time points, the influence of depressive symptoms on gait speed diminished. CONCLUSION: The negative effect of depressive symptoms on physical function may decrease over time as knee OA progresses.

Time-varying treatment effect modification of oral analgesic effectiveness by depressive symptoms in knee osteoarthritis: an application of structural nested mean models in a prospective cohort.

BACKGROUND: Depressive symptoms are common in knee osteoarthritis (OA), exacerbate knee pain severity and may influence outcomes of oral analgesic treatments. The aim was to assess whether oral analgesic effectiveness in knee OA varies by fluctuations in depressive symptoms. METHODS: The sample included Osteoarthritis Initiative (OAI) participants not treated with oral analgesics at enrolment (n = 1477), with radiographic disease at the first follow-up visit (defined as the index date). Oral analgesic treatment and depressive symptoms, assessed with the Center for Epidemiological Studies Depression [(CES-D) score ≥16] Scale, were measured over three annual visits. Knee pain severity was measured at visits adjacent to treatment and modifier using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscale (rescaled range = 0-100). Structural nested mean models (SNMMs) estimated causal mean differences in knee pain severity comparing treatment versus no treatment. RESULTS: The average causal effects of treated versus not treated for observations without depressive symptoms showed negligible differences in knee pain severity. However, causal mean differences in knee pain severity comparing treatment versus no treatment among observations with depressive symptoms increased over time from -0.10 [95% confidence interval (CI): -9.94, 9.74] to -16.67 (95% CI: -26.33, -7.01). Accordingly, the difference in average causal effects regarding oral analgesic treatment for knee pain severity between person-time with and without depressive symptoms was largest (-16.53; 95% CI: -26.75, -6.31) at the last time point. Cumulative treatment for 2 or 3 years did not yield larger causal mean differences. CONCLUSIONS: Knee OA patients with persistent depressive symptoms and chronic pain may derive more analgesic treatment benefit than those without depressive symptoms and less pain.

Duloxetine plus exercise for knee osteoarthritis and depression: A feasibility study.

Objective: To assess the feasibility of a 24-week, center-based, aerobic exercise program plus duloxetine to treat symptomatic knee osteoarthritis (OA) and major depression. Design: Patients with symptomatic knee OA and major depression were recruited between August 2021 and November 2022 from the University of Maryland and VA Maryland Health Care Systems and Baltimore metropolitan area using medical records and advertisements. The intervention included 1) supervised treadmill walking 3 times weekly and 2) duloxetine starting at 30 â€‹mg each day and titrating up to the optimal dosage of 60 â€‹mg daily. Data collection occurred at baseline and 12- and 24-weeks follow-up. Feasibility was evaluated from recruitment rates, reasons for drop out, and treatment adherence. Clinical measures included the Knee Injury and Osteoarthritis Outcome Score (KOOS) and the Hamilton Depression Rating Scale (HAM-D). Results: Among 377 interested participants, 9 patients were enrolled, and 1 completed treatment. The most common reason reported for not prescreening was time commitment (n â€‹= â€‹39), many patients did not satisfy depression screening criteria (n â€‹= â€‹45), and most enrolled participants were not experiencing a major depressive episode (n â€‹= â€‹6). The single treated participant was 100 â€‹% adherent to duloxetine and depression severity decreased (HAM-D â€‹= â€‹25 to 1), but compliance to supervised exercise was only 26 â€‹%, and knee pain severity changed little (KOOS â€‹= â€‹41.7 to 44.4). Conclusions: This intervention had low feasibility. Time commitment to supervised exercise sessions reduced accessibility, and depression defined by diagnostic criteria precluded knee OA patients with depressive symptoms not a meeting case-level diagnosis from receiving treatment. Clinical trial registration number: NCT04111627.

"Caregiving is teamwork " Information sharing in home care for older adults with disabilities living in the community.

AIM: We examined information sharing between direct care workers, family caregivers, and clinicians involved in the care of older adults with disabilities. METHODS: Semi-structured interviews with N = 11 representatives of home care agencies ("residential service agencies" in Maryland). RESULTS: Work system and process characteristics relevant to information sharing included: (1) using electronic management systems and patient portals to communicate within agencies and with clinicians, (2) implementing tools to gather information about client goals, preferences, and routines, and (3) relying on family members for information about clients' needs. Participants did not report differences in dementia-related care coordination; however, dementia-related adaptations involved additional considerations for navigating relationships with family and standardizing processes to communicate with clinicians. CONCLUSION: Findings highlight care demands experienced by direct care workers and support calls to better coordinate information sharing between interdisciplinary care teams.

Mobile Health School Screening and Telemedicine Referral to Improve Access to Specialty Care in Rural Alaska: Integrating Mixed Methods Data to Contextualize Trial Outcomes.

OBJECTIVES: To understand factors associated with outcomes in a cluster-randomized controlled trial that evaluated a telemedicine specialty referral intervention for school hearing screenings in 15 rural Alaskan communities. DESIGN: Hearing Norton Sound was a mixed methods cluster-randomized controlled trial that compared a telemedicine specialty referral pathway (intervention) to a standard primary care referral pathway (control) for school hearing screenings. As a mixed methods trial, both quantitative and qualitative data were collected, analyzed, and integrated. Main trial results are published elsewhere, but integration of community-specific quantitative outcomes and qualitative results have not yet been reported. The constant comparative method was used to analyze qualitative data from semistructured interviews with six stakeholder groups across all 15 communities. Descriptive statistics were used to describe community-specific proportions of follow-up in both trial years. Qualitative and quantitative results were integrated to reveal relationships between contextual factors and follow-up outcomes across communities. RESULTS: The Hearing Norton Sound trial enrolled 1481 children from October 2017 to March 2019, with a total of 790 children requiring referral. Of the children who referred in the telemedicine specialty referral pathway communities (intervention), 68.5% received follow-up (268/391), compared to 32.1% (128/399) in primary care referral communities (control)(previously reported). When broken down by community, the mean proportion receiving follow-up was 75.26% (SD 22.5) and 37.9% (SD 11.4) for the telemedicine specialty referral communities and primary care referral communities, respectively. For qualitative data collection, semistructured interviews were conducted with 101 individuals between December 2018 and August 2019. Six stakeholder groups participated: elders (n = 14), parents (n = 25), children (n = 11), teachers/school staff (n = 18), principals (n = 6), and healthcare providers/clinic staff (n = 27). Six overall factors related to the outcomes of the telemedicine specialty referral pathway emerged during analysis: clinic capacity, personnel ownership and engagement, scheduling, telemedicine equipment/processes, communication, and awareness of the need for follow-up. We integrated these factors with the community-specific follow-up percentages and found associations for four of the six qualitative factors: clinic capacity, personnel ownership and engagement, communication, and awareness. An association was not seen for scheduling and telemedicine equipment/processes, which had variable relationships with the follow-up outcome. CONCLUSIONS: The Hearing Norton Sound trial demonstrated that a telemedicine specialty referral pathway can close the gap on children lost to follow up after school hearing screening. As a whole, the intervention profoundly increased the proportion of children receiving follow-up, but there was variability in outcomes within and between communities. To understand this variability, we analyzed community-specific intervention outcomes alongside community member feedback on factors related to the intervention. We identified four key factors that contributed to the success of the intervention. Attention to these factors will be essential to successful adaptation and implementation of this telemedicine specialty referral intervention and other similar interventions in future work in rural Alaska and beyond.

Prevalence of Childhood Hearing Loss in Rural Alaska.

OBJECTIVES: Childhood hearing loss has well-known lifelong consequences. Certain rural populations are at higher risk for infection-related hearing loss. For Alaska Native children, historical data on hearing loss prevalence suggest a higher burden of infection-related hearing loss, but updated prevalence data are urgently needed in this high-risk population. DESIGN: Hearing data were collected as part of two school-based cluster-randomized trials in 15 communities in rural northwest Alaska over two academic years (2017-2019). All enrolled children from preschool to 12th grade were eligible. Pure-tone thresholds were obtained using standard audiometry and conditioned play when indicated. The analysis included the first available audiometric assessment for each child (n = 1634 participants, 3 to 21 years), except for the high-frequency analysis, which was limited to year 2 when higher frequencies were collected. Multiple imputation was used to quantify the prevalence of hearing loss in younger children, where missing data were more frequent due to the need for behavioral responses. Hearing loss in either ear was evaluated using both the former World Health Organization (WHO) definition (pure-tone average [PTA] > 25 dB) and the new WHO definition (PTA ≥ 20 dB), which was published after the study. Analyses with the new definition were limited to children 7 years and older due to incomplete data obtained on younger children at lower thresholds. RESULTS: The overall prevalence of hearing loss (PTA > 25 dB; 0.5, 1, 2, 4 kHz) was 10.5% (95% confidence interval [CI], 8.9 to 12.1). Hearing loss was predominately mild (PTA >25 to 40 dB; 8.9%, 95% CI, 7.4 to 10.5). The prevalence of unilateral hearing loss was 7.7% (95% CI, 6.3 to 9.0). Conductive hearing loss (air-bone gap of ≥ 10 dB) was the most common hearing loss type (9.1%, 95% CI, 7.6 to 10.7). Stratified by age, hearing loss (PTA >25 dB) was more common in children 3 to 6 years (14.9%, 95% CI, 11.4 to 18.5) compared to children 7 years and older (8.7%, 95% CI, 7.1 to 10.4). In children 7 years and older, the new WHO definition increased the prevalence of hearing loss to 23.4% (95% CI, 21.0 to 25.8) compared to the former definition (8.7%, 95% CI, 7.1 to 10.4). Middle ear disease prevalence was 17.6% (95% CI, 15.7 to 19.4) and was higher in younger children (23.6%, 95% CI, 19.7 to 27.6) compared to older children (15.2%, 95% CI, 13.2 to 17.3). High-frequency hearing loss (4, 6, 8kHz) was present in 20.5% (95% CI, 18.4 to 22.7 [PTA >25 dB]) of all children and 22.8% (95% CI, 20.3 to 25.3 [PTA >25 dB]) and 29.7% (95% CI, 27.0 to 32.4 [PTA ≥ 20 dB]) of children 7 years and older (limited to year 2). CONCLUSIONS: This analysis represents the first prevalence study on childhood hearing loss in Alaska in over 60 years and is the largest cohort with hearing data ever collected in rural Alaska. Our results highlight that hearing loss continues to be common in rural Alaska Native children, with middle ear disease more prevalent in younger children and high-frequency hearing loss more prevalent with increasing age. Prevention efforts may benefit from managing hearing loss type by age. Lastly, continued research is needed on the impact of the new WHO definition of hearing loss on field studies.

Intersection of multiple factors shape Korean American caregiver experience in dementia caregiving.

BACKGROUND AND OBJECTIVES: Studies have shown that cultural norms such as filial responsibility and familism operate in the Korean American caregiving context. The purpose of our study is to understand the practice of Korean American caregivers who provide care to a family member living with dementia and their dementia care support needs. MATERIALS AND METHODS: We conducted 2 focus groups and individual semi-structured interviews with a total of 20 Korean American caregivers. We used inductive thematic analysis to guide coding and generation of themes. RESULTS: Three themes were identified; 1) intersectionality in the Korean American caregiver experience, 2) complex family dynamics, and 3) dementia care barriers and caregiver support needs. Within the dyadic relationship and the family, cultural identity, generational, acculturational, and language factors shaped the caregiver experience. The need to navigate bicultural norms could lead to tensions but also provide opportunity for caregivers to consider self-care and use external supports to decrease the work of caregiving. Family was the unit of caregiving and caregiving was divided among family members based on acculturation and language fluency. Caregivers desired both medical information combined with knowledge that experienced lay support could provide. Support that reflects their cultural context was valued. DISCUSSION: Findings suggest the importance of understanding the diversity of response to strong elder care norms among Korean American caregivers and the intersection of multiple factors that influence their caregiving experience. Integrating acculturation and generational assessments may be useful as a way to tailor interventions to optimize engagement in dementia care interventions.

Telemedicine Referral to Improve Access to Specialty Care for Preschool Children in Rural Alaska: A Cluster-Randomized Controlled Trial.

OBJECTIVES: Preschool programs provide essential preventive services, such as hearing screening, but in rural regions, limited access to specialists and loss to follow-up compound rural health disparities. We conducted a parallel-arm cluster-randomized controlled trial to evaluate telemedicine specialty referral for preschool hearing screening. The goal of this trial was to improve timely identification and treatment of early childhood infection-related hearing loss, a preventable condition with lifelong implications. We hypothesized that telemedicine specialty referral would improve time to follow-up and the number of children receiving follow-up compared with the standard primary care referral. DESIGN: We conducted a cluster-randomized controlled trial in K-12 schools in 15 communities over two academic years. Community randomization occurred within four strata using location and school size. In the second academic year (2018-2019), an ancillary trial was performed in the 14 communities that had preschools to compare telemedicine specialty referral (intervention) to standard primary care referral (comparison) for preschool hearing screening. Randomization of communities from the main trial was used for this ancillary trial. All children enrolled in preschool were eligible. Masking was not possible because of timing in the second year of the main trial, but referral assignment was not openly disclosed. Study team members and school staff were masked throughout data collection, and statisticians were blinded to allocation during analysis. Preschool screening occurred once, and children who were referred for possible hearing loss or ear disease were monitored for follow-up for 9 months from the screening date. The primary outcome was time to ear/hearing-related follow-up from the date of screening. The secondary outcome was any ear/hearing follow-up from screening to 9 months. Analyses were conducted using an intention-to-treat approach. RESULTS: A total of 153 children were screened between September 2018 and March 2019. Of the 14 communities, 8 were assigned to the telemedicine specialty referral pathway (90 children), and 6 to the standard primary care referral pathway (63 children). Seventy-one children (46.4%) were referred for follow-up: 39 (43.3%) in the telemedicine specialty referral communities and 32 (50.8%) in the standard primary care referral communities. Of children referred, 30 (76.9%) children in telemedicine specialty referral communities and 16 (50.0%) children in standard primary care referral communities received follow-up within 9 months (Risk Ratio = 1.57; 95% confidence interval [CI], 1.22 to 2.01). Among children who received follow-up, median time to follow-up was 28 days (interquartile range [IQR]: 15 to 71) in telemedicine specialty referral communities compared with 85 days (IQR: 26 to 129) in standard primary care referral communities. Mean time to follow-up for all referred children was 4.5 (event time ratio = 4.5; 95% CI, 1.8 to 11.4; p = 0.045) times faster in telemedicine specialty referral communities compared with standard primary care referral communities in the 9-month follow-up time frame. CONCLUSIONS: Telemedicine specialty referral significantly improved follow-up and reduced time to follow-up after preschool hearing screening in rural Alaska. Telemedicine referrals could extend to other preventive school-based services to improve access to specialty care for rural preschool children.

The Context of Caregiving in Heart Failure: A Dyadic, Mixed Methods Analysis.

BACKGROUND: Caregiving for persons with heart failure (HF) varies based on the individual, family, and home contexts of the dyad, yet the dyadic context of HF caregiving is poorly understood. OBJECTIVE: The aim of this study was to explore dyadic perspectives on the context of caregiving for persons with HF. METHODS: Family caregivers and persons with HF completed surveys and semistructured interviews. Investigators also photographed caregiving areas to complement home environment data. Descriptive qualitative analysis resulted in 7 contextual domains, and each domain was rated as strength, need, or neutral. We grouped dyads by number of challenging domains of context, categorizing dyads as high (≥3 domains), moderate (1-2 domains), or minimal (0 domains) needs. Quantitative instruments included the 36-item Short Form Health Survey, ENRICHD Social Support, HF Symptom Severity, and Zarit Burden Interview. We applied the average score of each quantitative measure to the groups derived from the qualitative analysis to integrate data in a joint display. RESULTS: The most common strength was the dyadic relationship, and the most challenging domain was caregiving intensity. Every dyad had at least 2 domains of strengths. Of 12 dyads, high-needs dyads (n = 3) had the worst average score for 7 of 10 instruments including caregiver and patient factors. The moderate-needs dyads (n = 6) experienced the lowest caregiver social support and mental health, and the highest burden. CONCLUSION: Strengths and needs were evident in all patient-caregiver dyads with important distinctions in levels of need based on assessment of multiple contextual domains. Comprehensive dyadic and home assessments may improve understanding of unmet needs and improve intervention tailoring.

Racial Disparity in Outcomes Among Prostate Cancer Patients in the Post-Affordable Care Act Period.

INTRODUCTION: Our objective was to assess whether Medicaid expansion is associated with reduced racial disparity in quality of care measured as 30-day mortality, 90-day mortality, and 30-day readmission in prostate cancer patients receiving surgery. METHODS: We used the National Cancer Database to extract a cohort of African American and White men diagnosed with prostate cancer between 2004 and 2015 and surgically treated. We used 2004-2009 data to observe preexisting racial disparity in outcomes. We used 2010-2015 data to assess racial disparity in outcomes and the interaction of race and Medicaid expansion status. RESULTS: Between 2004 and 2009, 179,762 men met our criteria. In this period, African American patients reported higher hazard of 30- and 90-day mortality and higher odds of 30-day readmission compared to White patients. Between 2010 and 2015, 174,985 men met our criteria. Of these 84% were White and 16% were African American. Main effects models showed that compared to White men, African American men had higher odds of 30-day mortality (OR=1.96, 95% CI = 1.46, 2.67), 90-day mortality (OR=1.40, 95% CI = 1.11, 1.77), and 30-day readmission (OR=1.28, 95% CI = 1.19, 1.38).The interactions between race and Medicaid expansion were not significant (P = .1306, .9499, and .5080, respectively). CONCLUSIONS: Improved access to care via Medicaid expansion may not translate into reduced racial disparity in quality-of-care outcomes in prostate cancer patients treated surgically. System-level factors such as availability of and referrals to care, and complex socioeconomic structure may also play a role in improving quality of care and reducing disparities.

Trajectory of Depression among Prostate Cancer Patients: A Secondary Analysis of a Randomized Controlled Trial.

Background: While psychological difficulties, such as depression, among prostate cancer patients are known, their longitudinal burden remains understudied. We assessed the burden of depression across low-, intermediate- and high-risk prostate cancer groups, and the association between regret and long-term depression. Methods: Secondary analysis of data from a multi-centered randomized controlled study among localized prostate cancer patients was carried out. Assessments were performed at baseline, and at 3-, 6-, 12- and 24-month follow-up. Depression was assessed using the Center for Epidemiologic Studies Depression (CES-D) scale. A CES-D score ≥ 16 indicates high depression. Regret was measured using the regret scale of the Memorial Anxiety Scale for Prostate Cancer (MAX-PC). The proportion of patients with high depression was compared over time, for each risk category. Logistic regression was used to assess the association between regret, and long-term depression after adjusting for age, race, insurance, smoking status, marital status, income, education, employment, treatment, number of people in the household and study site. Results: The study had 743 localized prostate cancer patients. Median depression scores at 6, 12 and 24 months were significantly larger than the baseline median score, overall and for the three prostate cancer risk groups. The proportion of participants with high depression increased over time for all risk groups. Higher regret at 24-month follow-up was significantly associated with high depression at 24-month follow-up, after adjusting for covariates. Conclusions: A substantial proportion of localized prostate cancer patients continued to experience long-term depression. Patient-centered survivorship care strategies can help reduce depression and regret, and improve outcomes in prostate cancer care.

Analysis of action planning, achievement and life purpose statements in an intervention to support caregivers of persons with heart failure.

BACKGROUND: Caregivers of persons living with heart failure (HF) experience uncertainty related to heart failure trajectory and caregiving demands. Caregiver Support is a nurse-led intervention consisting of a well-being assessment, development of a life purpose statement, and action planning related to self-care and support for caregivers. OBJECTIVES: The goal of this study was to describe the caregivers' action plans, action plan achievement and life purpose statements. METHODS: We used inductive content analysis to code life purpose statements and action plans by 2 coders. Descriptive statistics were used to describe the average number of action plans set per caregiver, the average number of themes coded per action plan and life purpose statement, and the status of goal achievement (i.e., by thematic domain, subdomains). Goal achievement was defined categorically: Achieved, not achieved, and not assessed. The achievement rate was calculated as the proportion of achieved action plans out of the total number of assessed action plans. RESULTS: The sample (n = 22) was predominantly women, spousal caregivers, and an average age of 62±14.2 years. Thirty-six percent of caregivers were Black and 41% reported financial strain. Action plans comprised five categories: personal health and well-being, social support, home environment, instrumental support and other. The most common topics of life purpose statements were faith and self-care/actualization. Of 85 action plans, 69 were assessed and 66.7% were achieved. CONCLUSIONS: These findings highlight the diversity of values and needs of caregivers and provides insights for additional person-centered support.

Agency and Mental Health Among Peruvian Older Adults During the COVID-19 Lockdown.

OBJECTIVES: To explore the experiences of older Peruvian adults living in urban areas of Lima under lockdown due to the National COVID-19 Emergency, this study analyzes how older adults (aged 60 and older) exercise agency while also living with the negative impacts of coronavirus disease 2019 (COVID-19) and related control measures. METHODS: Between August and December 2020, our research team conducted a telephone-based, qualitative study, in which we undertook semistructured interviews with a purposive sample of low-income older adults living with chronic multimorbidities and limited resources. Forty older adults, 24 women and 16 men, with a mean age of 72 years, participated in the study. For data analysis, we employed thematic analysis with a predominantly inductive approach. RESULTS: Older adults demonstrated several forms of agency to regulate emotions, maintain crucial bonds, foster social relationships, and seek economic and food security. Older adults experienced entertainment and support by caring for pets, undertaking farm work, and practicing their religious beliefs. For several participants and their families, quarantine was an opportunity to strengthen family relationships and learn new technologies. Older adults and their families reorganized themselves to assume new roles and perform activities that improved self-worth and confidence, thereby improving their well-being and mental health. DISCUSSION: Peruvian older adults exerted agency in different ways to respond to and sustain their mental health during the COVID-19 lockdown. Policymakers should value and recognize the agency of older adults when planning future health responses.

Changing the Paradigm for School Hearing Screening Globally: Evaluation of Screening Protocols From Two Randomized Trials in Rural Alaska.

OBJECTIVES: Diagnostic accuracy was evaluated for various screening tools, including mobile health (mHealth) pure-tone screening, tympanometry, distortion product otoacoustic emissions (DPOAE), and inclusion of high frequencies to determine the most accurate screening protocol for identifying children with hearing loss in rural Alaska where the prevalence of middle ear disease is high. DESIGN: Hearing screening data were collected as part of two cluster randomized trials conducted in 15 communities in rural northwest Alaska. All children enrolled in school from preschool to 12th grade were eligible. Analysis was limited to data collected 2018 to 2019 (n = 1449), when both trials were running and measurement of high frequencies were included in the protocols. Analyses included estimates of diagnostic accuracy for each screening tool, as well as exploring performance by age and grade. Multiple imputation was used to assess diagnostic accuracy in younger children, where missing data were more prevalent due to requirements for conditioned responses. The audiometric reference standard included otoscopy, tympanometry, and high frequencies to ensure detection of infection-related and noise-induced hearing loss. RESULTS: Both the mHealth pure-tone screen and DPOAE screen performed better when tympanometry was added to the protocol (increase in sensitivity of 19.9%, 95% Confidence Interval (CI): 15.9 to 24.1 for mHealth screen, 17.9%, 95% CI: 14.0 to 21.8 for high-frequency mHealth screen, and 10.4%, 95% CI: 7.5 to 13.9 for DPOAE). The addition of 6 kHz to the mHealth pure-tone screen provided an 8.7 percentage point improvement in sensitivity (95% CI: 6.5 to 11.3). Completeness of data for both the reference standard and the mHealth screening tool differed substantially by age, due to difficulty with behavioral testing in young children. By age 7, children were able to complete behavioral testing, and data indicated that high-frequency mHealth pure-tone screen with tympanometry was the superior tool for children 7 years and older. For children 3 to 6 years of age, DPOAE plus tympanometry performed the best, both for complete data and multiply imputed data, which better approximates accuracy for children with missing data. CONCLUSIONS: This study directly evaluated pure-tone, DPOAE, and tympanometry tools as part of school hearing screening in rural Alaskan children (3 to 18+ years). Results from this study indicate that tympanometry is a key component in the hearing screening protocol, particularly in environments with higher prevalence of infection-related hearing loss. DPOAE is the preferred hearing screening tool when evaluating children younger than 7 years of age (below 2nd grade in the United States) due to the frequency of missing data with behavioral testing in this age group. For children 7 years and older, the addition of high frequencies to pure-tone screening increased the accuracy of screening, likely due to improved identification of hearing loss from noise exposure. The lack of a consistent reference standard in the literature makes comparing across studies challenging. In our study with a reference standard inclusive of otoscopy, tympanometry, and high frequencies, less than ideal sensitivities were found even for the most sensitive screening protocols, suggesting more investigation is necessary to ensure screening programs are appropriately identifying noise- and infection-related hearing loss in rural, low-resource settings.

"At least we finally found out what it was": Dementia diagnosis in minoritized populations.

BACKGROUND: Disparities in diagnosis persist among persons living with dementia (PLWD); most research on delayed diagnosis relies on medical records or administrative claims. This study aimed to identify factors that delay or facilitate dementia diagnoses in racial or ethnic minoritized PLWD and elicit care partner perspectives on timing and effects of diagnosis. METHODS: Maryland-based participants cared for a PLWD age 60 or older, self-identified as Black/African/African-American, Asian, or Hispanic/Latino, and spoke English. Nineteen care partner in-depth, semi-structured interviews were conducted and analyzed using conventional qualitative content analysis methods. RESULTS: Biological, sociocultural, and environmental factors delayed dementia diagnosis. Memory loss was the most common early symptom, but the onset was often subtle or perceived as normal aging. Stigma and secrecy surrounding dementia influenced recognition and discussion of dementia among families and communities. Diagnoses were family-initiated and started in primary care. Care partners were divided in their perceptions of diagnosis timeliness and whether earlier diagnosis would have changed outcomes. Family reactions to dementia diagnoses varied; most participants expressed a strong sentiment of service and duty to care for older family members. Participants overwhelmingly felt the benefits of obtaining a dementia diagnosis outweighed harms. CONCLUSIONS: Numerous factors affect dementia diagnosis in racial and ethnic minoritized PLWD. Normalization of brain health discussions and systematic, proactive discussion and detection of dementia in primary care may address multilevel barriers and facilitators to diagnosis. Systems-level and community-led public health interventions may also help address disparities in brain health education and dementia diagnosis.

Community Perspectives on Hearing Loss in Rural Alaska.

OBJECTIVES: The aim of this study is to present an explanatory model of hearing loss in the Bering Strait region of Alaska in order to contextualize the results of a cluster randomized trial and propose implications for regional hearing-related health care. DESIGN: To promote ecological validity, or the generalizability of trial findings to real world experiences, qualitative methods (focus groups and interviews) were used within a mixed methods cluster randomized trial evaluating school hearing screening and follow-up processes in 15 communities in the Bering Strait region of Alaska. Focus groups were held between April and August 2017, and semistructured interviews were conducted between December 2018 and August 2019. Convenience sampling was used for six of the 11 focus groups to capture broad community feedback. Purposive sampling was used for the remaining five focus groups and for all interviews to capture a variety of experiences with hearing loss. Audio recordings of focus groups and interviews were transcribed, and both notes and transcripts were deidentified. All notes and transcripts were included in the analysis. The constant comparative method was used to develop a codebook by iteratively moving between transcripts and preliminary themes. Researchers then used this codebook to code data from all focus groups and interviews using qualitative analysis software (NVIVO 12, QSR International) and conducted thematic analyses to distill the findings presented in this article. RESULTS: Participants in focus groups (n = 116) and interviews (n = 101) shared perspectives in three domains: etiology, impact, and treatment of hearing loss. Regarding etiology, participants emphasized noise-induced hearing loss but also discussed infection-related hearing loss and various causes of ear infections. Participants described the impact of hearing loss on subsistence activities, while also detailing social, academic, and economic consequences. Participants described burdensome treatment pathways that are repetitive and often travel and time intensive. Communication breakdowns within these pathways were also described. Some participants spoke positively of increased access via onsite hearing health care services in "field clinics" as well as via telemedicine services. Others described weaknesses in these processes (infrequent field clinics and communication delays in telemedicine care pathways). Participants also described home remedies and stigma surrounding the treatment for hearing loss. CONCLUSIONS: Patient-centered health care requires an understanding of context. Explanatory models of illness are context-specific ways in which patients and their networks perceive and describe the experience of an illness or disability. In this study, we documented explanatory models of hearing loss to foster ecological validity and better understand the relevance of research findings to real-life hearing-related experiences. These findings suggest several areas that should be addressed in future implementation of hearing health care interventions elsewhere in rural Alaska, including management of repetitious treatments, awareness of infection-mediated hearing loss, mistrust, and communication breakdowns. For hearing-related health care in this region, these findings suggest localized recommendations for approaches for prevention and treatment. For community-based hearing research, this study offers an example of how qualitative methods can be used to generate ecologically valid (i.e., contextually grounded) findings.

Continuity of care and advanced prostate cancer.

BACKGROUND: Continuity of care is an important element of advanced prostate cancer care due to the availability of multiple treatment options, and associated toxicity. However, the association between continuity of care and outcomes across different racial groups remains unclear. OBJECTIVE: To assess the association of provider continuity of care with outcomes among Medicare fee-for-service beneficiaries with advanced prostate cancer and its variation by race. DESIGN: Retrospective cohort study using Surveillance, Epidemiology, and End Results (SEER)-Medicare data. SUBJECTS: African American and white Medicare beneficiaries aged 66 or older, and diagnosed with advanced prostate cancer between 2000 and 2011. At least 5 years of follow-up data for the cohort was used. MEASURES: Short-term outcomes were emergency room (ER) visits, hospitalizations, and cost during acute survivorship phase (2-year post-diagnosis), and mortality (all-cause and prostate cancer-specific) during the follow-up period. We calculated continuity of care using Continuity of Care Index (COCI) and Usual Provider Care Index (UPCI), for all visits, oncology visits, and primary care visits in acute survivorship phase. We used Poisson models for ER visits and hospitalizations, and log-link GLM for cost. Cox model and Fine-Gray competing risk models were used for survival analysis, weighted by propensity score. We performed similar analysis for continuity of care in the 2-year period following acute survivorship phase. RESULTS: One unit increase in COCI was associated with reduction in short-term ER visits (incidence rate ratio [IRR] = 0.65, 95% confidence interval [CI] 0.64, 0.67), hospitalizations (IRR = 0.65, 95% CI 0.64, 0.67), and cost (0.64, 95% CI 0.61, 0.66) and lower hazard of long-term mortality. Magnitude of these associations differed between African American and white patients. We observed comparable results for continuity of care in the follow-up period. CONCLUSIONS: Continuity of care was associated with improved outcomes. The benefits of higher continuity of care were greater for African Americans, compared to white patients. Advanced prostate cancer survivorship care must integrate appropriate strategies to promote continuity of care.

Association of caregiver strain with the trajectory of quality of life in Parkinson's disease.

We aimed to identify caregiver characteristics associated with the trajectory of quality of life (QoL) in Parkinson's disease (PD). We fit a growth mixture model to longitudinal data from the Parkinson Foundation Parkinson's Outcomes Project (POP) to identify the heterogeneity of QOL trajectories in PD. We then used multinomial logistic regression to model baseline factors that predicted class membership. Baseline growth models were fit to QOL scores measured over 4 disease duration time points. A random intercept and slope model was determined to best fit the data. Next, growth mixture models (1, 2, 3, 4, and 5-class) were fit with covariates (Hoehn & Yahr, sex, and depression) and a three-class model was found to provide the best fit. Class 1 (problematic class (10.0%)) represented individuals with poor QOL at baseline and minor improvement over time. Class 2 (moderate class (32.6%)) represented individuals with moderate QOL at baseline with slight worsening over time. Class 3 (favorable class (56.9%)) represented individuals with good QOL at baseline and slight worsening over time. Multinomial regression revealed that lower caregiver strain, better mobility, and better verbal fluency at baseline predicted membership in the favorable compared to the moderate class. Worse mobility and younger age predicted membership in the problematic compared to the moderate class. While previous studies have reported on the association between mobility and cognition, the novel finding of an association between caregiver strain and PD QOL trajectory suggests caregiver strain is important to measure and address in future research and practice.
