RESUMO

Objectives: This study aims to examine the change in financial strain, health behaviors, and psychological well-being of family caregivers of older adults during the COVID-19 pandemic and explore the differences in mental health outcomes by gender, race, and relationship status. Methods: Using the 2020 National Health and Aging Trends Study COVID-19 supplement, our sample included 2026 family caregivers of older adults. Structural equation modeling was conducted. Results: Caregivers with financial strain showed worse mental health than those with no financial strain. Female or adult children caregivers reported significantly less time walking, more financial strain, and a higher level of negative mental health outcomes compared to male or spouse caregivers; non-White caregivers reported greater positive mental health outcomes compared to White caregivers during the pandemic. Discussion: Health professionals should consider the financial and mental health impact of COVID-19 among family caregivers when designing and delivering caregiver support programs. Innovation: This study provides nationally representative estimates of several important health behaviors and health outcomes for caregivers of older adults during and after the COVID-19 pandemic, helping to fill the knowledge gap about the characteristics of caregivers whose health and well-being were most affected by the pandemic.

RESUMO

INTRODUCTION: Acute right iliac fossa (RIF) pain is a common presenting symptom in surgical patients, with a wide range of differentials, particularly in premenopausal females. This study explores ultrasound usage in the management of women aged 16-55 years presenting with RIF pain. METHODS: A total of 1,082 patients who presented to a tertiary hospital over 12 months were included. Data were collected from patients' electronic records, including initial clinical impression, imaging, management, operative findings, histology and subsequent hospital attendances within 6 weeks and within 6 months. RESULTS: Following clinical assessment, 607 (56%) of patients underwent an ultrasound. Of these, 280 (25.9%) patients received no radiological imaging on initial presentation, and 252 (42%) had pathology identified on ultrasound. The most common finding was an ovarian cyst, closely followed by unexplained free pelvic fluid. Of the 607 patients scanned, 29 (4.8%) had an ultrasound diagnosis of appendicitis; 254 of 1,082 (23.5%) patients underwent operative management. Of the 254 patients who had surgery, 179 (70.5%) had preoperative imaging. Of the 29 (11.4%) cases where the intraoperative finding was gynaecological, 15 (51.7%) cases had not had any preoperative imaging. The negative appendicectomy rate was 21.3% (45/211). Of the 45 patients who had a histologically normal appendix, 22 (48.9%) had not had any previous imaging. Ultrasound had a specificity of 78% for diagnosing appendicitis. CONCLUSIONS: In patients who underwent operative management, a negative finding or finding not requiring surgical management was associated with no preoperative imaging. This supports the use of ultrasound scans as an adjunct in a multimodal approach to the assessment of women presenting with RIF pain.

RESUMO

OBJECTIVES: The incidence of hospital-acquired conditions (HACs) is a serious public health issue with implications ranging from patient morbidity and mortality to negative financial impacts on patients and health care systems. Despite substantial efforts to address and reduce HACs, research into the effect of quality improvement programs is inconclusive. This study seeks to better understand the relationship between repeated reimbursement penalties and improvement in HAC quality scores. METHODS: A quantitative comparative analysis of U.S. health care data was conducted. Data on quality outcomes and hospital characteristics were sourced from the Hospital-Acquired Condition Reduction Program from fiscal years 2018 and 2019 and the Centers for Medicare & Medicaid Services Inpatient Prospective Payment System impact files, respectively. RESULTS: In total, 3123 U.S. hospitals were analyzed to compare differences between total HAC scores of hospitals with and without penalties in consecutive years. Hospitals with repeated penalties had significantly greater improvement in scores ( t497.262 = -13.00, P < 0.001), and the impact was greatest in small hospitals (<100 beds). Repeated penalties had a smaller impact on disproportionate share hospitals (Cohen d = 0.73). Among all hospitals, the effect of repeated penalties was large (Cohen d = 0.75). CONCLUSIONS: This study suggests that repeated penalties can improve quality scores in U.S. hospitals. However, the effect may be exaggerated for smaller hospitals and those that serve patient populations with a relatively higher socioeconomic status. The reason disproportionate share hospitals did not show as much improvement as nondisproportionate hospitals may be because hospitals serving vulnerable populations often have fewer resources.

RESUMO

General inpatient (GIP) hospice care is used only minimally for hospice patients, and more than a quarter of Medicare hospice facilities do not provide GIP care. To determine the impact of hospices' capacity to provide on emergency department use during hospice enrollment and live discharge from hospice, we used Surveillance, Epidemiology, and End Results-Medicare linked data and CMS Provider of Services data from 2007 to 2013 from ten states and two metropolitan regions. Grouping hospices into three GIP care provision categories: 1) no-GIP; 2) GIP-contract; and 3) GIP-IHF where hospices directly provide GIP care in their own inpatient hospice facility (IHF), we built a multilevel logistic model that accounted for unobserved hospice characteristics. Nearly 9% of the study sample received GIP care, of which 82% received such care in the last week of discharge. GIP-IHF hospices had lower live discharge rates than no-GIP hospices (AOR: .61; 95% CI: .47-.79; P < .001) and GIP-contract hospices (AOR: .84; 95% CI: .70-1.00; P < .05). Similarly, GIP-contract hospices were also associated with a decreased risk of live discharge, compared to no-GIP hospices (AOR: .76; CI: .62-.92; P < .05). There was no difference in emergency department use between no-GIP hospices and hospices with such capacity. Our results suggest that hospices capable of providing GIP care have lower live discharge rates than their counterparts. However, the fact that GIP care tends to be provided too close to death limits its effectiveness in preventing avoidable emergency department use.

RESUMO

Background: COVID-19 deeply affected the health and well-being of older adults. This study examines health behavior change and the interrelationships between health behaviors, financial difficulties, and depressive symptoms among older adults across gender and race during the pandemic. Methods: Using Rounds 1, 5, and 10 of the National Health and Aging Trends Study (NHATS) linked with the NHATS COVID-19 dataset, our sample included Medicare beneficiaries aged 65 or older in the U.S. (N = 3,118). We modeled the interrelationships between health behaviors, financial difficulties, and depressive symptoms using a structural equation model. Results: Female participants reported less walking, more changes in eating habits, less sleeping, and less alcohol consumption during the pandemic than before the pandemic compared to male participants. Compared to White, Non-White participants showed higher proportions of experiencing financial difficulties, less walking, less vigorous activity, and changes in time spent eating and sleeping during than before the pandemic. Financial difficulties was positively associated with depressive symptoms and sedentary behavior. Active behavior was negatively associated with depressive symptoms, while sedentary behavior was positively associated with more depressive symptoms. Discussion: Health professionals should consider health behaviors and financial difficulties when intervening on depressive symptoms experienced by older adults since the pandemic.

RESUMO

BACKGROUND: Telehealth was expanded worldwide during the COVID-19 pandemic to deliver essential care remotely to patients, including those receiving palliative care. Bipartisan groups of politicians in the United States call for continuing the expanded Medicare coverage of telehealth services beyond the pandemic period. The aim was to understand telehealth's benefits and risks to hospice and palliative care patients and their families. METHODS: We conducted a cross-sectional survey of 595 caregivers of seriously ill patients and interviewed 25 hospice leaders across the United States. We used multiple linear regression to analyze the survey data and qualitative methods to determine themes from the interview data. RESULTS: Our survey showed that a good internet connection, better access to video, and the patient being younger than 65 years old were associated with greater satisfaction with telehealth. The hospice leader interviews highlighted that telehealth can enhance or detract from quality care, depending on the function; confusion over telehealth policies and concern for abuse exists; and telehealth during the pandemic has spurred on technology-enabled innovation and improvements, especially for resource-constrained hospice and palliative care organizations. CONCLUSIONS: Telehealth used during the pandemic showed that it may work for certain hospice and palliative care services. As telehealth coverage expands, it is important to address its risks and shortcomings upfront. When designed and implemented with the patient and equity in mind, telehealth has the potential to improve access to hospice and palliative care for all.

RESUMO

Early diagnosis and access to behavioral health services can improve the health outcomes for young children suffering from mental illness. Often, children and their families' behavioral health needs are not met due to a broken local system of care. Developing a deep understanding of the situation by exploring all stakeholders' needs across a community in conjunction with a comprehensive review of the existing scientific literature prepared one rural midwestern county to build a better local system of care. This study's unique aspects include visual mapping using art in focus groups and close collaboration between a public mental health board, academic faculty, student researchers, local behavioral health organizations, and schools. Major themes found about the existing barriers were dysfunctional patterns in families, lack of resources, reliance on the school system, and lack of access to healthcare professionals. Other communities can use this approach as a model for a local needs assessment.

RESUMO

OBJECTIVE: To examine hospices' approaches to improving the current racial/ethnic hospice utilisation disparity. METHODS: During June and July 2020, we conducted in-depth, semistructured interviews with 22 hospice leaders from across the USA. The interviews focused on inclusive strategy approaches. We analysed the data using qualitative methods. RESULTS: Multiple themes emerged about racial/ethnic minority inclusion strategies: (1) hospices tailor strategies to the local communities they serve; (2) improvement involves addressing social determinants of health that extend beyond end-of-life care; (3) costs of strategies are not a primary concern and the benefits are worth the costs; and (4) hospices want to do more to improve their efforts. CONCLUSIONS: Hospices want to improve racial/ethnic minority inclusion and can take specific action steps to educate community members about hospice and provide an environment within hospice care that is welcoming to all. Hospice-targeted programmes and policies that facilitate language translation, diversity in staffing, enhanced community outreach, and leadership and staff collaboration regarding inclusion may help hospices achieve success in their efforts toward racial/ethnic minority inclusion.

RESUMO

Background: Racial/ethnic minority populations in the United States are less likely to utilize hospice services nearing their end of life, potentially diminishing their quality of care while also increasing medical costs. Objective: Explore the minority hospice utilization gap from the hospice perspective by examining perceived barriers and facilitators as well as practices and policies. Method: Qualitative surveys were conducted with 41 hospices across the United States. Qualitative data analysis included performing a limited content analysis, including the identification of themes and representative quotations. Results: Commonly reported barriers to hospice care for racial/ethnic minorities included culture/beliefs, mistrust of the medical system, and language barriers. A major theme pertaining to successful minority hospice enrollment was an inclusive culture that provided language services, staff cultural training, and a diverse staff. Another major theme was the importance of community outreach activities that extended beyond the medical community and forming relationships with churches, racial/ethnic minority community leaders, and Native American reservations. Conclusion: The importance of incorporating a culture of inclusivity by forming committees, providing language services, and offering culturally competent care emerged in this qualitative study. Building strong external relationships with community groups such as churches is a strategy used to increase racial/ethnic minority utilization of hospice.

RESUMO

BACKGROUND: Parkinson's disease (PD) affects approximately 145,519 people in the UK. Speech impairments are common with a reported prevalence of 68%, which increase physical and mental demands during conversation, reliance on family and/or carers, and the likelihood of social withdrawal reducing quality of life. In the UK, two approaches to Speech and Language Therapy (SLT) intervention are commonly available: National Health Service (NHS) SLT or Lee Silverman Voice Treatment (LSVT LOUD®). NHS SLT is tailored to the individuals' needs per local practice typically consisting of six to eight weekly sessions; LSVT LOUD® comprises 16 sessions of individual treatment with home-based practice over 4 weeks. The evidence-base for their effectiveness is inconclusive. METHODS/DESIGN: PD COMM is a phase III, multicentre, three-arm, unblinded, randomised controlled trial. Five hundred and forty-six people with idiopathic PD, reporting speech or voice problems will be enrolled. We will exclude those with a diagnosis of dementia, laryngeal pathology or those who have received SLT for speech problems in the previous 2 years. Following informed consent and completion of baseline assessments, participants will be randomised in a 1:1:1 ratio to no-intervention control, NHS SLT or LSVT LOUD® via a central computer-generated programme, using a minimisation procedure with a random element, to ensure allocation concealment. Participants randomised to the intervention groups will start treatment within 4 (NHS SLT) or 7 (LSVT LOUD®) weeks of randomisation. PRIMARY OUTCOME: Voice Handicap Index (VHI) total score at 3 months. Secondary outcomes include: VHI subscales, Parkinson's Disease Questionnaire-39; Questionnaire on Acquired Speech Disorders; EuroQol-5D-5 L; ICECAP-O; resource utilisation; adverse events and carer quality of life. Mixed-methods process and health economic evaluations will take place alongside the trial. Assessments will be completed before randomisation and at 3, 6 and 12 months after randomisation. The trial started in December 2015 and will run for 77 months. Recruitment will take place in approximately 42 sites around the UK. DISCUSSION: The trial will test the hypothesis that SLT is effective for the treatment of speech or voice problems in people with PD compared to no SLT. It will further test whether NHS SLT or LSVT LOUD® provide greater benefit and determine the cost-effectiveness of both interventions. TRIAL REGISTRATION: International Standard Randomised Controlled Trials Number (ISRCTN) Registry, ID: 12421382. Registered on 18 April 2016.

RESUMO

BACKGROUND: Prader-Willi syndrome (PWS) is a neurogenetic syndrome with an associated behavioural phenotype and a high incidence of behaviours of concern and psychiatric co-morbidity. These associated behaviours and co-morbidities are not well addressed by existing interventions, and they impact significantly on affected individuals and their caregivers. METHODS: We undertook a national survey of the needs of individuals with PWS and their families in Ireland. In this paper, we report on the parent/caregiver-reported mental health, behavioural and access to services. RESULTS: Over 50% of individuals with PWS in this survey had at least one reported psychiatric diagnosis, the most common diagnosis was anxiety. The most commonly reported behaviours in children were skin picking, repetitive questioning, difficulty transitioning and non-compliance. The same four behaviours were reported by caregivers as being the most commonly occurring in adolescents and adults in addition to food-seeking behaviours. Increased needs for mental health services were also reported by caregivers. Individuals with PWS had an average wait of 22 months for an appointment with a psychologist and 4 months for an appointment with a psychiatrist. CONCLUSION: This study highlighted high levels of psychiatric co-morbidities and behavioural concerns in individuals with PWS in Ireland. The findings of this study suggest that there is an urgent need to provide specialist psychiatric and behavioural interventions to manage complex mental health and behavioural needs to better support individuals with PWS and reduce caregiver burden.

RESUMO

Background: Medicare spends about 20% more on the last year of life for Black and Hispanic people than White people. With lower hospice utilization rates, racial/ethnic minorities receive fewer hospice-related benefits such as lesser symptoms, lower costs, and improved quality of life. For-profit hospices have higher dropout rates than nonprofit hospices, yet target racial/ethnic minority communities more through community outreach. This analysis examined the relationship between hospice utilization and for-profit hospice status and conducted an economic analysis of racial/ethnic minority utilization. Method: Cross-sectional analysis of 2014 Centers for Medicare & Medicaid Services (CMS), U.S. Census, and Hospice Analytics data. Measures included Medicare racial/ethnic minority hospice utilization, for-profit hospice status, estimated cost savings, and several demographic and socioeconomic variables. Results: The prevalence of for-profit hospices was associated with significantly increased hospice utilization among racial/ethnic minorities. With savings of about $2,105 per Medicare hospice enrollee, closing the gap between the White and racial/ethnic minority populations would result in nearly $270 million in annual cost savings. Discussion: Significant disparities in hospice use related to hospice for-profit status exist among the racial/ethnic minority Medicare population. CMS and state policymakers should consider lower racial/ethnic minority hospice utilization and foster better community outreach at all hospices to decrease patient costs and improve quality of life.

RESUMO

Health care providers are in a unique position to address patients' health behaviors and social determinants of health, factors like income and social support that can significantly impact health. There is a need to better understand the risk behaviors of a population that providers may counsel (i.e., those who are insured and have a provider.) Using the 2015 and 2016 CDC's Behavioral Risk Factor Surveillance System, we examine the prevalence of health behaviors and the existence of disparities in health behaviors based on social determinants among American adults. Our sample included noninstitutionalized adults aged 18 to 64 years, in the U.S. (N > 300,000). We used multivariate logistic regression analysis to assess the independent effects of income, education, sex, race, and metropolitan status on nine key health behaviors. Among adults with insurance and a provider (n > 200,000): 1) rates of engaging in poor health behaviors ranged from 6.4% (heavy drinking) to 68.1% (being overweight or obese), 2) rural residence, lower income, and lower education were associated with decreased clinical preventive services, 3) lower income and lower education were associated with lifestyle-related risks, and 4) being black was associated with receiving more cancer screenings, no influenza vaccination, inadequate physical activity, and being overweight or obese. Insured adults, with a provider, are not meeting recommended guidelines for health behaviors. Significant disparities in health behaviors related to social factors exist among this group. Health care providers and organizations may find it helpful to consider these poor health behaviors and disparities when determining strategies to address SDOH.

RESUMO

BACKGROUND/PURPOSE: Duchenne Mmuscular Ddystrophy (DMD) related cardiomyopathy is associated with significant perioperative mortality. Cardiac MRI (CMR) has not previously been systematically evaluated as pre-operative assessment tool for heart function in DMD. Our aim was to establish whether CMR versus echocardiography contributes to pre-operative DMD assessment. METHODS: Case records were retrospectively reviewed of 35 consecutive DMD boys who underwent evaluation for surgical procedures between 2010 and 2013. RESULTS: Echocardiography revealed a median left ventricular (LV) shortening fraction (SF) of 29/% (range: 7-44). 37% of boys (13/35) had abnormal SF <25%, 66% (23/35) showed hypokinesia and 26% (9/35) had LV dilatation. CMR revealed a median left ventricular ejection fraction (LVEF) of 52% (range: 27-67%). 57% of boys (20/35) had abnormal LVEF <55%, 71% (25/35) had hypokinesia, and 82% late gadolinium enhancement. Extensive versus minimal late gadolinium enhancement was associated with reduced left ventricular ejection fraction (48% vs 58%; p = 0.003) suggesting more severe cardiomyopathy. Although echocardiography shortening fraction correlated with CMR ejection fraction (rs = 0.67; p < 0.001), three-quarter of echocardiography studies had suboptimal scanning windows and in 26% measurements significantly over- or underestimated left-ventricular function compared to CMR. CONCLUSION: Our findings clearly demonstrate the added value of CMR versus echocardiography in assessing DMD-cardiomyopathy. Particularly when echocardiographic scanning windows are suboptimal, CMR should be considered to allow accurate pre-operative cardiac assessment.

RESUMO

PURPOSE: The management of rectal cancer relies on accurate MRI staging. Multi-modal treatments can downstage rectal cancer prior to surgery and may have an effect on MRI accuracy. We aim to correlate the findings of MRI staging of rectal cancer with histological analysis, the effect of neoadjuvant therapy on this and the implications of circumferential resection margin (CRM) positivity following neoadjuvant therapy. METHODS: An analysis of histological data and radiological staging of all cases of rectal cancer in a single centre between 2006 and 2011 were conducted. RESULTS: Two hundred forty-one patients had histologically proved rectal cancer during the study period. One hundred eighty-two patients underwent resection. Median age was 66.6 years, and male to female ratio was 13:5. R1 resection rate was 11.1%. MRI assessments of the circumferential resection margin in patients without neoadjuvant radiotherapy were 93.6 and 88.1% in patients who underwent neoadjuvant radiotherapy. Eighteen patients had predicted positive margins following chemoradiotherapy, of which 38.9% had an involved CRM on histological analysis. CONCLUSIONS: MRI assessment of the circumferential resection margin in rectal cancer is associated with high accuracy. Neoadjuvant chemoradiotherapy has a detrimental effect on this accuracy, although accuracy remains high. In the presence of persistently predicted positive margins, complete resection remains achievable but may necessitate a more radical approach to resection.

RESUMO

Improved antiretroviral therapies are needed for the treatment of HIV-infected infants, given the rapid progression of the disease and drug resistance resulting from perinatal exposure to antiretrovirals. We examined longitudinal pharmacokinetics (PK) data from a clinical trial of lopinavir/ritonavir (LPV/r) in HIV-infected infants in whom therapy was initiated at less than 6 months of age. A population PK analysis was performed using NONMEM to characterize changes in lopinavir (LPV) PK relating to maturational changes in infants, and to assess dosing requirements in this population. We also investigated the relationship between LPV PK and viral dynamic response. Age and ritonavir concentrations were the only covariates found to be significant. Population PK of LPV was characterized by high apparent clearance (CL/F) in young infants, which decreased with increasing age. Although younger infants had lower LPV concentrations, the viral dynamics did not correlate with initial LPV exposure. Monte Carlo simulations demonstrated that WHO weight band-based dosing recommendations predicted therapeutic LPV concentrations and provided drug exposure levels comparable to those resulting from US Food and Drug Administration (FDA)-suggested dosing regimens.

RESUMO

INTRODUCTION: Little research exists on the prevalence of evidence-based tobacco cessation practices in workplaces, employer promotion of state-sponsored quitlines and predictors of these practices. METHODS: Cross-sectional analysis of the 2008 Healthy Worksite Survey, a telephone survey administered to Washington employers with 50 or more employees (n=693). The objectives were to describe workplaces' implementation of evidence-based tobacco cessation practices and identify key predictors of implementation in order to highlight opportunities for interventions. RESULTS: Among these employers, 38.6% promoted quitting tobacco, and 33.8% offered insurance coverage for cessation medications and counselling, 27.5% referred no-smoking violators to cessation services, and 5.7% included the state-sponsored quitline in health promotion messages. Larger workplaces and workplaces with a wellness staff, committee or coordinator had greater insurance coverage for tobacco cessation, communications promoting tobacco cessation, and promotion of the state-sponsored quitline (p<0.01). Workplaces with a wellness staff, committee or coordinator referred more violators of no-smoking policies to cessation services (p<0.01). CONCLUSIONS: In Washington State workplaces do little to promote tobacco cessation by their employees. The lack of tobacco cessation promoting practices at small businesses, restaurants and bars, and businesses without wellness personnel indicates an opportunity for finding and reaching current smokers at businesses with limited resources. By adopting inexpensive prevention efforts, such as promoting the state-sponsored tobacco cessation quitline, employers can help employees quit smoking and, thereby, assist in improving employee health and lower medical costs.

RESUMO

AIM: The purpose of this study was to determine from a range of vertical jump and rebound tests, which were the most suitable to measure different forms of stretch-shortening cycle function, and whether such tests could be used interchangeably. METHODS: Two hundred and fifty male youths (age, 12.26 ± 2.94 years; body mass, 47.11 ± 16.91 kg; standing height, 152.98 ± 17.40 cm; and sitting height, 76.89 ± 9.32 cm) were tested for squat and countermovement jump height, reactive strength index (during a maximal hopping test), and leg stiffness (during a sub-maximal hopping test). Stepwise multiple regressions were used to examine the relationships between different measures of SSC function in youths. RESULTS: Absolute leg stiffness was best predicted by body mass (r2=62%), however the explained variance was significantly reduced when normalized to leg length and body mass (r2=15.3%). Squat jump height best explained the total variance for reactive strength index (r2=53.9%), whilst countermovement and squat jump height were the best predictors of each other (r2=86%). CONCLUSION: Results would suggest that the test protocols used in this study were representative of different forms of SSC performance.
