ABSTRACT

BACKGROUND: Timely follow-up after cardiovascular hospitalization is recommended to monitor recovery, titrate medications, and coordinate care. OBJECTIVE: To describe trends and disparities in follow-up after acute myocardial infarction (AMI) and heart failure (HF) hospitalizations. DESIGN: Retrospective cohort study. SETTING: Medicare. PARTICIPANTS: Medicare fee-for-service beneficiaries hospitalized between 2010 and 2019. MEASUREMENTS: Receipt of a cardiology visit within 30 days of discharge. Multivariable logistic regression models were used to estimate changes over time overall and across 5 sociodemographic characteristics on the basis of known disparities in cardiovascular outcomes. RESULTS: The cohort included 1 678 088 AMI and 4 245 665 HF hospitalizations. Between 2010 and 2019, the rate of cardiology follow-up increased from 48.3% to 61.4% for AMI hospitalizations and from 35.2% to 48.3% for HF hospitalizations. For both conditions, follow-up rates increased for all subgroups, yet disparities worsened for Hispanic patients with AMI and patients with HF who were Asian, Black, Hispanic, Medicaid dual eligible, and residents of counties with higher levels of social deprivation. By 2019, the largest disparities were between Black and White patients (AMI, 51.9% vs. 59.8%, difference, 7.9 percentage points [pp] [95% CI, 6.8 to 9.0 pp]; HF, 39.8% vs. 48.7%, difference, 8.9 pp [CI, 8.2 to 9.7 pp]) and Medicaid dual-eligible and non-dual-eligible patients (AMI, 52.8% vs. 60.4%, difference, 7.6 pp [CI, 6.9 to 8.4 pp]; HF, 39.7% vs. 49.4%, difference, 9.6 pp [CI, 9.2 to 10.1 pp]). Differences between hospitals explained 7.3 pp [CI, 6.7 to 7.9 pp] of the variation in follow-up for AMI and 7.7 pp [CI, 7.2 to 8.1 pp]) for HF. LIMITATION: Generalizability to other payers. CONCLUSION: Equity-informed policy and health system strategies are needed to further reduce gaps in follow-up care for patients with AMI and patients with HF.

ABSTRACT

BACKGROUND: Management of elevated blood pressure (BP) during hospitalization varies widely, with many hospitalized adults experiencing BPs higher than those recommended for the outpatient setting. PURPOSE: To systematically identify guidelines on elevated BP management in the hospital. DATA SOURCES: MEDLINE, Guidelines International Network, and specialty society websites from 1 January 2010 to 29 January 2024. STUDY SELECTION: Clinical practice guidelines pertaining to BP management for the adult and older adult populations in ambulatory, emergency department, and inpatient settings. DATA EXTRACTION: Two authors independently screened articles, assessed quality, and extracted data. Disagreements were resolved via consensus. Recommendations on treatment targets, preferred antihypertensive classes, and follow-up were collected for ambulatory and inpatient settings. DATA SYNTHESIS: Fourteen clinical practice guidelines met inclusion criteria (11 were assessed as high-quality per the AGREE II [Appraisal of Guidelines for Research & Evaluation II] instrument), 11 provided broad BP management recommendations, and 1 each was specific to the emergency department setting, older adults, and hypertensive crises. No guidelines provided goals for inpatient BP or recommendations for managing asymptomatic moderately elevated BP in the hospital. Six guidelines defined hypertensive urgency as BP above 180/120 mm Hg, with hypertensive emergencies requiring the addition of target organ damage. Hypertensive emergency recommendations consistently included use of intravenous antihypertensives in intensive care settings. Recommendations for managing hypertensive urgencies were inconsistent, from expert consensus, and focused on the emergency department. Outpatient treatment with oral medications and follow-up in days to weeks were most often advised. In contrast, outpatient BP goals were clearly defined, varying between 130/80 and 140/90 mm Hg. LIMITATION: Exclusion of non-English-language guidelines and guidelines specific to subpopulations. CONCLUSION: Despite general consensus on outpatient BP management, guidance on inpatient management of elevated BP without symptoms is lacking, which may contribute to variable practice patterns.

ABSTRACT

We previously performed a genome-wide association study (GWAS) to identify the genetic basis of praziquantel (PZQ) response in schistosomes, identifying two quantitative trait loci situated on chromosomes 2 and 3. We reanalyzed this GWAS using the latest (version 10) genome assembly showing that a single locus on chromosome 3, rather than two independent loci, determines drug response. These results reveal that PZQ response is monogenic and demonstrates the importance of high-quality genomic information.

ABSTRACT

The human malaria parasite Plasmodium falciparum is globally widespread, but its prevalence varies significantly between and even within countries. Most population genetic studies in P. falciparum focus on regions of high transmission where parasite populations are large and genetically diverse, such as sub-Saharan Africa. Understanding population dynamics in low transmission settings, however, is of particular importance as these are often where drug resistance first evolves. Here, we use the Pacific Coast of Colombia and Ecuador as a model for understanding the population structure and evolution of Plasmodium parasites in small populations harboring less genetic diversity. The combination of low transmission and a high proportion of monoclonal infections means there are few outcrossing events and clonal lineages persist for long periods of time. Yet despite this, the population is evolutionarily labile and has successfully adapted to changes in drug regime. Using newly sequenced whole genomes, we measure relatedness between 166 parasites, calculated as identity by descent (IBD), and find 17 distinct but highly related clonal lineages, six of which have persisted in the region for at least a decade. This inbred population structure is captured in more detail with IBD than with other common population structure analyses like PCA, ADMIXTURE, and distance-based trees. We additionally use patterns of intra-chromosomal IBD and an analysis of haplotypic variation to explore past selection events in the region. Two genes associated with chloroquine resistance, crt and aat1, show evidence of hard selective sweeps, while selection appears soft and/or incomplete at three other key resistance loci (dhps, mdr1, and dhfr). Overall, this work highlights the strength of IBD analyses for studying parasite population structure and resistance evolution in regions of low transmission, and emphasizes that drug resistance can evolve and spread in small populations, as will occur in any region nearing malaria elimination.

ABSTRACT

BACKGROUND: Disparities in opioid prescribing among racial and ethnic groups have been observed in outpatient and emergency department settings, but it is unknown whether similar disparities exist at discharge among hospitalized older adults. OBJECTIVE: To determine filled opioid prescription rates on hospital discharge by race/ethnicity among Medicare beneficiaries. DESIGN: Retrospective cohort study. PARTICIPANTS: Medicare beneficiaries 65 years or older discharged from hospital in 2016, without opioid fills in the 90 days prior to hospitalization (opioid-naïve). MAIN MEASURES: Race/ethnicity was categorized by the Research Triangle Institute (RTI), grouped as Asian/Pacific Islander, Black, Hispanic, other (American Indian/Alaska Native/unknown/other), and White. The primary outcome was an opioid prescription claim within 2 days of hospital discharge. The secondary outcome was total morphine milligram equivalents (MMEs) among adults with a filled opioid prescription. KEY RESULTS: Among 316,039 previously opioid-naïve beneficiaries (mean age, 76.8 years; 56.2% female), 49,131 (15.5%) filled an opioid prescription within 2 days of hospital discharge. After adjustment, Black beneficiaries were 6% less likely (relative risk [RR] 0.94, 95% CI 0.91-0.97) and Asian/Pacific Islander beneficiaries were 9% more likely (RR 1.09, 95% CI 1.03-1.14) to have filled an opioid prescription when compared to White beneficiaries. Among beneficiaries with a filled opioid prescription, mean total MMEs were lower among Black (356.9; adjusted difference - 4%, 95% CI - 7 to - 1%), Hispanic (327.0; adjusted difference - 7%, 95% CI - 10 to - 4%), and Asian/Pacific Islander (328.2; adjusted difference - 8%, 95% CI - 12 to - 4%) beneficiaries when compared to White beneficiaries (409.7). CONCLUSIONS AND RELEVANCE: Black older adults were less likely to fill a new opioid prescription after hospital discharge when compared to White older adults and received lower total MMEs. The factors contributing to these differential prescribing patterns should be investigated further.

ABSTRACT

BACKGROUND: Timely primary care follow-up after acute care discharge may improve outcomes. OBJECTIVE: To evaluate whether post-discharge follow-up rates differ among patients discharged from hospitals directly affiliated with their primary care clinic (same-site), other hospitals within their health system (same-system), and hospitals outside their health system (outside-system). DESIGN: Retrospective cohort study. PATIENTS: Adult patients of five primary care clinics within a 14-hospital health system who were discharged home after a hospitalization or emergency department (ED) stay. MAIN MEASURES: Primary care visit within 14 days of discharge. A multivariable Poisson regression model was used to estimate adjusted rate ratios (aRRs) and risk differences (aRDs), controlling for sociodemographics, acute visit characteristics, and clinic characteristics. KEY RESULTS: The study included 14,310 discharges (mean age 58.4 [SD 19.0], 59.5% female, 59.5% White, 30.3% Black), of which 57.7% were from the same-site, 14.3% same-system, and 27.9% outside-system. By 14 days, 34.5% of patients discharged from the same-site hospital received primary care follow-up compared to 27.7% of same-system discharges (aRR 0.88, 95% CI 0.79 to 0.98; aRD - 6.5 percentage points (pp), 95% CI - 11.6 to - 1.5) and 20.9% of outside-system discharges (aRR 0.77, 95% CI [0.70 to 0.85]; aRD - 11.9 pp, 95% CI - 16.2 to - 7.7). Differences were greater for hospital discharges than ED discharges (e.g., aRD between same-site and outside-system - 13.5 pp [95% CI, - 20.8 to - 8.3] for hospital discharges and - 10.1 pp [95% CI, - 15.2 to - 5.0] for ED discharges). CONCLUSIONS: Patients discharged from a hospital closely affiliated with their primary care clinic were more likely to receive timely follow-up than those discharged from other hospitals within and outside their health system. Improving care transitions requires coordination across both care settings and health systems.

ABSTRACT

Higher therapy session frequency has been found to result in faster recovery, but few studies have considered that clients follow diverse trajectories of change in psychotherapy. It is unknown how session frequency may affect the sizes and shapes of change trajectories. The present study examined clients' change trajectories in weekly and biweekly therapy in a naturalistic setting, as well as predictors of these trajectories. Using a sample of 5,102 clients receiving 3-10 therapy sessions at a university counseling center, we identified 886 clients attending approximately weekly therapy and 1,753 clients attending approximately biweekly therapy. We examined the change trajectories of the weekly and biweekly samples using latent growth mixture modeling (LGMM). Three trajectories were identified in weekly therapy: slow change (78.33%), early improvement (17.61%), and worse before better (4.06%), and in biweekly therapy: slow change (80.38%), early improvement (13.52%), and worse before better (6.1%). The worse before better subgroup in weekly therapy experienced greater deterioration than those in biweekly therapy. The slow change and early improvement subgroups in weekly therapy showed treatment outcome comparable to those of their respective counterparts in biweekly therapy. Clients' intake symptoms, including eating concerns, frustration/anger, depression, and academic concerns, significantly predicted change trajectories. Compared to biweekly therapy, weekly therapy leads to higher chances of early improvement and shortens the duration of suffering but results in greater deterioration for individuals who deteriorate in therapy. The impact of session frequency on treatment outcome varies across clients, and session frequency should be adjusted individually. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

ABSTRACT

Little is known about encouraging help-seeking in non-English speaking settings and relatively little research has been directed to facilitate help-seeking among Chinese-speaking people. This study examined the effects of a multimedia intervention on barriers, attitudes, and intentions for seeking counseling in China. The multimedia intervention was informed by prior empirical research on models of help-seeking for counseling. A total of 200 participants were randomly assigned to one of the two conditions: (1) a help-seeking media-exposed intervention group and (2) a control group, who watched a hospital advertisement that was unrelated to mental health help-seeking. Results indicated that the intervention was effective at increasing both positive attitudes toward therapy and intentions to seek therapy. The intervention also improved participants' perceptions about treatment accessibility. This intervention is available and can be a resource for Chinese language populations (both within China and other countries), especially for immigrants, rural, and persons who might benefit from mental health treatments such as psychotherapy.

ABSTRACT

More than 60 zoonoses are linked to small mammals, including some of the most devastating pathogens in human history. Millions of museum-archived tissues are available to understand natural history of those pathogens. Our goal was to maximize the value of museum collections for pathogen-based research by using targeted sequence capture. We generated a probe panel that includes 39,916 80-bp RNA probes targeting 32 pathogen groups, including bacteria, helminths, fungi, and protozoans. Laboratory-generated, mock-control samples showed that we are capable of enriching targeted loci from pathogen DNA 2,882‒6,746-fold. We identified bacterial species in museum-archived samples, including Bartonella, a known human zoonosis. These results showed that probe-based enrichment of pathogens is a highly customizable and efficient method for identifying pathogens from museum-archived tissues.

ABSTRACT

BACKGROUND: Geographic variation in high-cost medical procedure utilization in the USA is not fully explained by patient factors but may be influenced by the supply of procedural physicians and marketing payments. OBJECTIVE: To examine the association between physician supply, medical device-related marketing payments to physicians, and utilization of knee arthroplasty (KA) and percutaneous coronary interventions (PCI) within hospital referral regions (HRRs). DESIGN: Cross-sectional analysis of data from the 2018 CMS Open Payments database and procedural utilization data from the CMS Provider Utilization and Payment database. PARTICIPANTS: Medicare-participating procedural cardiologists and orthopedic surgeons. MAIN MEASURES: Regional rates of PCIs and KAs per 100,000 Medicare fee-for-service (FFS) beneficiaries were estimated after adjustment for beneficiary demographics. KEY RESULTS: Across 306 HRRs, there were 109,301 payments (value $17,554,728) to cardiologists for cardiac stents and 68,132 payments (value $40,492,126) to orthopedic surgeons for prosthetic knees. Among HRRs, one additional interventional cardiologist was associated with an increase of 12.9 (CI, 9.3-16.5) PCIs per 100,000 beneficiaries, and one additional orthopedic surgeon was associated with an increase of 20.6 (CI, 16.9-24.4) KAs per 100,000 beneficiaries. A $10,000 increase in gift payments from stent manufacturers was associated with an increase of 26.0 (CI, 5.1-46.9) PCIs per 100,000 beneficiaries, while total and service payments were not associated with greater regional PCI utilization. A $10,000 increase in total payments from knee prosthetic manufacturers was associated with an increase of 2.9 (CI, 1.4-4.5) KAs per 100,000 beneficiaries, while a similar increase in gift and service payments was associated with an increase of 14.5 (CI, 5.0-24.1) and 3.4 (CI, 1.6-5.2) KAs, respectively. CONCLUSIONS: Among Medicare FFS beneficiaries, regional supply of physicians and receipt of industry payments were associated with greater use of PCIs and KAs. Relationships between payments and procedural utilization were more consistent for KAs, a largely elective procedure, compared to PCIs, which may be elective or emergent.

ABSTRACT

Characterising connectivity between geographically separated biological populations is a common goal in many fields. Recent approaches to understanding connectivity between malaria parasite populations, with implications for disease control efforts, have used estimates of relatedness based on identity-by-descent (IBD). However, uncertainty around estimated relatedness has not been accounted for. IBD-based relatedness estimates with uncertainty were computed for pairs of monoclonal Plasmodium falciparum samples collected from five cities on the Colombian-Pacific coast where long-term clonal propagation of P. falciparum is frequent. The cities include two official ports, Buenaventura and Tumaco, that are separated geographically but connected by frequent marine traffic. Fractions of highly-related sample pairs (whose classification using a threshold accounts for uncertainty) were greater within cities versus between. However, based on both highly-related fractions and on a threshold-free approach (Wasserstein distances between parasite populations) connectivity between Buenaventura and Tumaco was disproportionally high. Buenaventura-Tumaco connectivity was consistent with transmission events involving parasites from five clonal components (groups of statistically indistinguishable parasites identified under a graph theoretic framework). To conclude, P. falciparum population connectivity on the Colombian-Pacific coast abides by accessibility not isolation-by-distance, potentially implicating marine traffic in malaria transmission with opportunities for targeted intervention. Further investigations are required to test this hypothesis. For the first time in malaria epidemiology (and to our knowledge in ecological and epidemiological studies more generally), we account for uncertainty around estimated relatedness (an important consideration for studies that plan to use genotype versus whole genome sequence data to estimate IBD-based relatedness); we also use threshold-free methods to compare parasite populations and identify clonal components. Threshold-free methods are especially important in analyses of malaria parasites and other recombining organisms with mixed mating systems where thresholds do not have clear interpretation (e.g. due to clonal propagation) and thus undermine the cross-comparison of studies.

ABSTRACT

We studied whether counseling self-efficacy increases after taking a helping skills course as well as whether trainer (instructor) effects are associated with postclass self-efficacy. We surveyed 551 undergraduate students and 27 trainers in helping skills courses across three semesters at one large mid-Atlantic U.S. public university. We found that students reported greater counseling self-efficacy after taking the course. In addition, trainers accounted for small but significant amount of the variance (7%) in changes in counseling self-efficacy. There was evidence that the instructors' authoritative teaching style but not their facilitative interpersonal skills were associated with increases in students' counseling self-efficacy. Implications for helping skills training are discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

ABSTRACT

OBJECTIVE: We aim to examine how different trajectories of symptom change and working alliance in early psychotherapy predict treatment outcomes. METHOD: We performed a growth mixture model (GMM) to examine trajectories of symptom change and working alliance in the first five therapy sessions in a sample of 272 outpatients and tested the association of early symptom trajectories and alliance patterns with treatment outcome. RESULTS: We identified two symptom trajectories: high symptom/steady change (63.2%) and early improving (36.8%), and four alliance development patterns: undeveloped alliance (40.1%), strengthening moderate alliance (31.6%), optimal alliance (17.3%), and improved alliance (11%) in early psychotherapy. The symptom trajectories and alliance patterns both independently and interactively predicted treatment outcomes. The optimal alliance was generally associated with the best outcome. The effect of improved alliance on treatment outcome was moderated by symptom trajectories: for high symptom/steady change subgroup, the improved alliance was related to better treatment outcome, whereas for early improving subgroup, the improved alliance was associated with poorer outcome. CONCLUSIONS: Patients fell into different trajectories regarding symptom reduction and alliance development in early psychotherapy that affected final treatment outcome. Combining early symptom trajectories and alliance trajectories simultaneously can facilitate routine outcome monitoring and contribute to the prediction of treatment outcome.

ABSTRACT

OBJECTIVE: Text-based communication is becoming an increasingly salient feature of the psychotherapeutic landscape. Yet little is known about the factors distinguishing high- and low-quality therapeutic conversations taking place over this modality. Prior research on therapist effects has outlined several common factors associated with better clinical outcomes. But these common factors can only be researched in the context of text-based communication if they can be measured. Accordingly, we developed and validated a new behavioral task and coding system: the Facilitative Interpersonal Skills Performance Task for Text (FIS-T) to measure therapists' messaging quality across eight dimensions of facilitative interpersonal skill. METHODS: 1150 survey-takers rated the interpersonal dynamics and response difficulty of the FIS-T Task's text-based stimuli. The FIS-T was then administered to 64 therapists. RESULTS: The FIS-T stimuli displayed similar interpersonal dynamics to those elicited by the original FIS task, demonstrated a similar range of difficulties to those of the video-based stimuli of the original FIS Task, and showed high inter-rater reliability. CONCLUSIONS: The text-based FIS-T Task demonstrates high reliability and convergent validity with the original FIS Task, making it appropriate for use in assessing the common factors in text-based therapy. Future directions in the quality assessment of internet-delivered psychotherapies are discussed.

ABSTRACT

Schistosoma mansoni, a snail-borne, blood fluke that infects humans, was introduced into the Americas from Africa during the Trans-Atlantic slave trade. As this parasite shows strong specificity to the snail intermediate host, we expected that adaptation to South American Biomphalaria spp. snails would result in population bottlenecks and strong signatures of selection. We scored 475,081 single nucleotide variants in 143 S. mansoni from the Americas (Brazil, Guadeloupe and Puerto Rico) and Africa (Cameroon, Niger, Senegal, Tanzania, and Uganda), and used these data to ask: (i) Was there a population bottleneck during colonization? (ii) Can we identify signatures of selection associated with colonization? (iii) What were the source populations for colonizing parasites? We found a 2.4- to 2.9-fold reduction in diversity and much slower decay in linkage disequilibrium (LD) in parasites from East to West Africa. However, we observed similar nuclear diversity and LD in West Africa and Brazil, suggesting no strong bottlenecks and limited barriers to colonization. We identified five genome regions showing selection in the Americas, compared with three in West Africa and none in East Africa, which we speculate may reflect adaptation during colonization. Finally, we infer that unsampled populations from central African regions between Benin and Angola, with contributions from Niger, are probably the major source(s) for Brazilian S. mansoni. The absence of a bottleneck suggests that this is a rare case of a serendipitous invasion, where S. mansoni parasites were pre-adapted to the Americas and able to establish with relative ease.

ABSTRACT

BACKGROUND: Patients with dementia are frequently hospitalized and may face barriers in post-discharge care. OBJECTIVE: To determine whether patients with dementia have an increased risk of adverse outcomes following discharge. DESIGN: Retrospective cohort study. SUBJECTS: Medicare beneficiaries hospitalized in 2016. MAIN MEASURES: Co-primary outcomes were mortality and readmission within 30 days of discharge. Multivariable logistic regression models were estimated to assess the risk of each outcome for patients with and without dementia accounting for demographics, comorbidities, frailty, hospitalization factors, and disposition. KEY RESULTS: The cohort included 1,089,109 hospitalizations of which 211,698 (19.3%) were of patients with diagnosed dementia (median (IQR) age 83 (76-89); 61.5% female) and 886,411 were of patients without dementia (median (IQR) age 76 (79-83); 55.0% female). At 30 days following discharge, 5.7% of patients with dementia had died compared to 3.1% of patients without dementia (adjusted odds ratio (aOR) 1.21; 95% CI 1.17 to 1.24). At 30 days following discharge, 17.7% of patients with dementia had been readmitted compared to 13.1% of patients without dementia (aOR 1.02; CI 1.002 to 1.04). Dementia was associated with an increased odds of readmission among patients discharged to the community (aOR 1.07, CI 1.05 to 1.09) but a decreased odds of readmission among patients discharge to nursing facilities (aOR 0.93, CI 0.90 to 0.95). Patients with dementia who were discharged to the community were more likely to be readmitted than those discharged to nursing facilities (18.9% vs 16.0%), and, when readmitted, were more likely to die during the readmission (20.7% vs 4.4%). CONCLUSIONS: Diagnosed dementia was associated with a substantially increased risk of mortality and a modestly increased risk of readmission within 30 days of discharge. Patients with dementia discharged to the community had particularly elevated risk of adverse outcomes indicating possible gaps in post-discharge services and caregiver support.

ABSTRACT

BACKGROUND: In 2014, hypertension guidelines for older adults endorsed increased use of fixed-dose combinations, prioritized thiazide diuretics and calcium channel blockers (CCBs) for Black patients, and no longer recommend beta-blockers as first-line therapy. OBJECTIVE: To evaluate older adults' antihypertensive use following guideline changes. DESIGN: Time series analysis. PATIENTS: Twenty percent national sample of Medicare Part D beneficiaries aged 66 years and older with hypertension. INTERVENTION: Eighth Joint National Committee (JNC8) guidelines MAIN MEASURES: Quarterly trends in prevalent and initial antihypertensive use were examined before (2008 to 2013) and after (2014 to 2017) JNC8. Analyses were conducted among all beneficiaries with hypertension, beneficiaries without chronic conditions that might influence antihypertensive selection (hypertension-only cohort), and among Black patients, given race-based guideline recommendations. KEY RESULTS: The number of beneficiaries with hypertension increased from 1,978,494 in 2008 to 2,809,680 in 2017, the proportions using antihypertensives increased from 80.3 to 81.2%, and the proportion using multiple classes and fixed-dose combinations declined (60.8 to 58.1% and 20.7 to 15.1%, respectively, all P<.01). Prior to JNC8, the use of angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, and CCBs was increasing. Use of CCBs as initial therapy increased more rapidly following JNC8 (relative change in quarterly trend 0.15% [95% CI, 0.13-0.18%), especially among Black beneficiaries (relative change 0.44% [95% CI, 0.21-0.68%]). Contrary to guidelines, the use of thiazides and combinations as initial therapy consistently decreased in the hypertension-only cohort (13.8 to 8.3% and 25.1 to 15.7% respectively). By 2017, 65.9% of Black patients in the hypertension-only cohort were initiated on recommended first-line or combination therapy compared to 80.3% of non-Black patients. CONCLUSIONS: Many older adults, particularly Black patients, continue to be initiated on antihypertensive classes not recommended as first-line, indicating opportunities to improve the effectiveness and equity of hypertension care and potentially reduce antihypertensive regimen complexity.

ABSTRACT

The outbreak of COVID-19 has resulted in increasing needs for mental health treatments and yet simultaneously posed great challenges to the delivery of in-person psychological services. The standard clinical practice suddenly shifted to the use of telepsychology. This study aimed to identify how therapists have been responding to the public health crisis and the rapid transition to telepsychology. We distributed a survey to 502 mental health providers to investigate the challenges and concerns of the delivery of clinical work during the pandemic. Our study found that most therapists (75.9%) transitioned to telepsychology without suspension of services. Therapists reported varied concerns regarding telepsychology, clinical practice, and their personal lives. The most common concerns identified were the use of therapeutic techniques in telepsychology, provision of remote services, and the practitioner's own health. Our findings also indicated that therapists who are students, female, sexual minorities, unpartnered, and working in public settings experienced relatively greater concerns. It may imperative to allocate more resources to those subgroups of therapists to facilitate their clinical work in telepsychology. This study contributed to our understanding of how the pandemic has impacted clinical work and may inform practitioners in coping with the current and any future public crises.

ABSTRACT

Importance: Medicare Advantage health plans covered 37% of beneficiaries in 2018, and coverage increased to 48% in 2022. Whether Medicare Advantage plans provide similar care for patients presenting with specific clinical conditions is unknown. Objective: To compare 30-day mortality and treatment for Medicare Advantage and traditional Medicare patients presenting with acute myocardial infarction (MI) from 2009 to 2018. Design, Setting, and Participants: Retrospective cohort study that included 557 309 participants with ST-segment elevation [acute] MI (STEMI) and 1 670 193 with non-ST-segment elevation [acute] MI (NSTEMI) presenting to US hospitals from 2009-2018 (date of final follow up, December 31, 2019). Exposures: Enrollment in Medicare Advantage vs traditional Medicare. Main Outcomes and Measures: The primary outcome was adjusted 30-day mortality. Secondary outcomes included age- and sex-adjusted rates of procedure use (catheterization, revascularization), postdischarge medication prescriptions and adherence, and measures of health system performance (intensive care unit [ICU] admission and 30-day readmissions). Results: The study included a total of 2 227 502 participants, and the mean age in 2018 ranged from 76.9 years (Medicare Advantage STEMI) to 79.3 years (traditional Medicare NSTEMI), with similar proportions of female patients in Medicare Advantage and traditional Medicare (41.4% vs 41.9% for STEMI in 2018). Enrollment in Medicare Advantage vs traditional Medicare was associated with significantly lower adjusted 30-day mortality rates in 2009 (19.1% vs 20.6% for STEMI; difference, -1.5 percentage points [95% CI, -2.2 to -0.7] and 12.0% vs 12.5% for NSTEMI; difference, -0.5 percentage points [95% CI, -0.9% to -0.1%]). By 2018, mortality had declined in all groups, and there were no longer statically significant differences between Medicare Advantage (17.7%) and traditional Medicare (17.8%) for STEMI (difference, 0.0 percentage points [95% CI, -0.7 to 0.6]) or between Medicare Advantage (10.9%) and traditional Medicare (11.1%) for NSTEMI (difference, -0.2 percentage points [95% CI, -0.4 to 0.1]). By 2018, there was no statistically significant difference in standardized 90-day revascularization rates between Medicare Advantage and traditional Medicare. Rates of guideline-recommended medication prescriptions were significantly higher in Medicare Advantage (91.7%) vs traditional Medicare patients (89.0%) who received a statin prescription (difference, 2.7 percentage points [95% CI, 1.2 to 4.2] for 2018 STEMI). Medicare Advantage patients were significantly less likely to be admitted to an ICU than traditional Medicare patients (for 2018 STEMI, 50.3% vs 51.2%; difference, -0.9 percentage points [95% CI, -1.8 to 0.0]) and significantly more likely to be discharged to home rather than to a postacute facility (for 2018 STEMI, 71.5% vs 70.2%; difference, 1.3 percentage points [95% CI, 0.5 to 2.1]). Adjusted 30-day readmission rates were consistently lower in Medicare Advantage than in traditional Medicare (for 2009 STEMI, 13.8% vs 15.2%; difference, -1.3 percentage points [95% CI, -2.0 to -0.6]; and for 2018 STEMI, 11.2% vs 11.9%; difference, 0.6 percentage points [95% CI, -1.5 to 0.0]). Conclusions and Relevance: Among Medicare beneficiaries with acute MI, enrollment in Medicare Advantage, compared with traditional Medicare, was significantly associated with modestly lower rates of 30-day mortality in 2009, and the difference was no longer statistically significant by 2018. These findings, considered with other outcomes, may provide insight into differences in treatment and outcomes by Medicare insurance type.

ABSTRACT

Objectives: This study examined the combined effect of therapist Facilitative Interpersonal Skills (FIS) and Training Status on experiential processes within therapy sessions. In this randomized trial of FIS and Training Status, we predicted that in-session experiential processes would be highest for the high FIS and trained therapist group and lowest for the low FIS and untrained therapists. Methods: Forty-five clients were selected from 2,713 undergraduates using a screening and clinical interview procedure. Twenty-three therapists were selected for their level of FIS (high vs. low) and Training (trainee vs. untrained) and each were assigned two clients for seven sessions each. Two different coder teams independently rated experiencing and narrative process from the third therapy session and computer analysis identified affect words from transcripts. Results: FIS×Training Status significantly interacted on the set of experiential process measures. Relative to all others, therapists who were in the low FIS / no training group had lower experiencing and reflexive content, but higher external content. Conclusions: The findings highlight the importance of therapist characteristics within therapy sessions. Therapists without training and with low interpersonal skills have sessions that are nearly devoid of content that focuses on client experiential processes and emotion.
