Medicare Advantage Health Risk Assessments Contribute Up To $12 Billion Per Year To Risk-Adjusted Payments.

With Medicare Advantage (MA) enrollment surpassing 50 percent of Medicare beneficiaries, accurate risk-adjusted plan payment rates are essential. However, artificially exaggerated coding intensity, where plans seek to enhance measured health risk through the addition or inflation of diagnoses, may threaten payment rate integrity. One factor that may play a role in escalating coding intensity is health risk assessments (HRAs)-typically in-home reviews of enrollees' health status-that enable plans to capture information about their enrollees. In this study, we evaluated the impact of HRAs on Hierarchical Condition Categories (HCC) risk scores, variation in this impact across contracts, and the aggregate payment impact of HRAs, using 2019 MA encounter data. We found that 44.4 percent of MA beneficiaries had at least one HRA. Among those with at least one HRA, HCC scores increased by 12.8 percent, on average, as a result of HRAs. More than one in five enrollees had at least one additional HRA-captured diagnosis, which raised their HCC score. Potential scenarios restricting the risk-score impact of HRAs correspond with $4.5-$12.3 billion in reduced Medicare spending in 2020. Addressing increased coding intensity due to HRAs will improve the value of Medicare spending and ensure appropriate payment in the MA program.

Post-hospitalization Care Transition Strategies for Patients with Substance Use Disorders: A Narrative Review and Taxonomy.

Hospitalizations represent important opportunities to engage individuals with substance use disorders (SUD) in treatment. For those who engage with SUD treatment in the hospital setting, tailored supports during post-discharge transitions to longitudinal care settings may improve care linkages, retention, and treatment outcomes. We updated a recent systematic review search on post-hospitalization SUD care transitions through a structured review of published literature from January 2020 through June 2023. We then added novel sources including a gray literature search and key informant interviews to develop a taxonomy of post-hospitalization care transition models for patients with SUD. Our updated literature search generated 956 abstracts not included in the original systematic review. We selected and reviewed 89 full-text articles, which yielded six new references added to 26 relevant articles from the original review. Our search of five gray literature sources yielded four additional references. Using a thematic analysis approach, we extracted themes from semi-structured interviews with 10 key informants. From these results, we constructed a taxonomy consisting of 10 unique SUD care transition models in three overarching domains (inpatient-focused, transitional, outpatient-focused). These models include (1) training and protocol implementation; (2) screening, brief intervention, and referral to treatment; (3) hospital-based interdisciplinary consult team; (4) continuity-enhanced interdisciplinary consult team; (5) peer navigation; (6) transitional care management; (7) outpatient in-reach; (8) post-discharge outreach; (9) incentivizing follow-up; and (10) bridge clinic. For each model, we describe design, scope, approach, and implementation strategies. Our taxonomy highlights emerging models of post-hospitalization care transitions for patients with SUD. An established taxonomy provides a framework for future research, implementation efforts, and policy in this understudied, but critically important, aspect of SUD care.

Palmer Station, Antarctica: A ground-based spaceflight analog suitable for validation of biomedical countermeasures for deep space missions.

Astronauts are known to exhibit a variety of immunological alterations during spaceflight including changes in leukocyte distribution and plasma cytokine concentrations, a reduction in T-cell function, and subclinical reactivation of latent herpesviruses. These alterations are most likely due to mission-associated stressors including circadian misalignment, microgravity, isolation, altered nutrition, and increased exposure to cosmic radiation. Some of these stressors may also occur in terrestrial situations. This study sought to determine if crewmembers performing winterover deployment at Palmer Station, Antarctica, displayed similar immune alterations. The larger goal was to validate a ground analog suitable for the evaluation of countermeasures designed to protect astronauts during future deep space missions. For this pilot study, plasma, saliva, hair, and health surveys were collected from Palmer Station, Antarctica, winterover participants at baseline, and at five winterover timepoints. Twenty-six subjects consented to participate over the course of two seasons. Initial sample processing was performed at Palmer, and eventually stabilized samples were returned to the Johnson Space Center for analysis. A white blood cell differential was performed (real time) using a fingerstick blood sample to determine alterations in basic leukocyte subsets throughout the winterover. Plasma and saliva samples were analyzed for 30 and 13 cytokines, respectively. Saliva was analyzed for cortisol concentration and three latent herpesviruses (DNA by qPCR), EBV, HSV1, and VZV. Voluntary surveys related to general health and adverse clinical events were distributed to participants. It is noteworthy that due to logistical constraints caused by COVID-19, the baseline samples for each season were collected in Punta Arenas, Chile, after long international travel and during isolation. Therefore, the Palmer pre-mission samples may not reflect a true normal 'baseline'. Minimal alterations were observed in leukocyte distribution during winterover. The mean percentage of monocyte concentration elevated at one timepoint. Plasma G-CSF, IL1RA, MCP-1, MIP-1ß, TNFα, and VEGF were decreased during at least one winterover timepoint, whereas RANTES was significantly increased. No statistically significant changes were observed in mean saliva cytokine concentrations. Salivary cortisol was substantially elevated throughout the entire winterover compared to baseline. Compared to shedding levels observed in healthy controls (23%), the percentage of participants who shed EBV was higher throughout all winterover timepoints (52-60%). Five subjects shed HSV1 during at least one timepoint throughout the season compared to no subjects shedding during pre-deployment. Finally, VZV reactivation, common in astronauts but exceptionally rare in ground-based stress analogs, was observed in one subject during pre-deployment and a different subject at WO2 and WO3. These pilot data, somewhat influenced by the COVID-19 pandemic, do suggest that participants at Palmer Station undergo immunological alterations similar to, but likely in reduced magnitude, as those observed in astronauts. We suggest that winterover at Palmer Station may be a suitable test analog for spaceflight biomedical countermeasures designed to mitigate clinical risks for deep space missions.

Mobilising context as complex and dynamic in evaluations of complex health interventions.

BACKGROUND: The relationship between healthcare interventions and context is widely conceived as involving complex and dynamic interactions over time. However, evaluations of complex health interventions frequently fail to mobilise such complexity, reporting context and interventions as reified and demarcated categories. This raises questions about practices shaping knowledge about context, with implications for who and what we make visible in our research. Viewed through the lens of case study research, we draw on data collected for the Triple C study (focused on Case study, Context and Complex interventions), to critique these practices, and call for system-wide changes in how notions of context are operationalised in evaluations of complex health interventions. METHODS: The Triple C study was funded by the Medical Research Council to develop case study guidance and reporting principles taking account of context and complexity. As part of this study, a one-day workshop with 58 participants and nine interviews were conducted with those involved in researching, evaluating, publishing, funding and developing policy and practice from case study research. Discussions focused on how to conceptualise and operationalise context within case study evaluations of complex health interventions. Analysis focused on different constructions and connections of context in relation to complex interventions and the wider social forces structuring participant's accounts. RESULTS: We found knowledge-making practices about context shaped by epistemic and political forces, manifesting as: tensions between articulating complexity and clarity of description; ontological (in)coherence between conceptualisations of context and methods used; and reified versions of context being privileged when communicating with funders, journals, policymakers and publics. CONCLUSION: We argue that evaluations of complex health interventions urgently requires wide-scale critical reflection on how context is mobilised - by funders, health services researchers, journal editors and policymakers. Connecting with how scholars approach complexity and context across disciplines provides opportunities for creatively expanding the field in which health evaluations are conducted, enabling a critical standpoint to long-established traditions and opening up possibilities for innovating the design of evaluations of complex health interventions.

Medicare Advantage Enrollment and Disenrollment Among Persons With Alzheimer Disease and Related Dementias.

Importance: Large enrollment growth has been observed in the Medicare Advantage program, but less is known about enrollment patterns among persons with Alzheimer disease and related dementias (ADRD). Objective: To evaluate patterns in Medicare Advantage enrollment and disenrollment among beneficiaries with or without ADRD. Design, Setting, and Participants: This cross-sectional study used 6 national data sources between January 1, 2011, and December 31, 2018. Analyses were performed between June 2021 and August 2022. The cohort comprised US Medicare beneficiaries with acute or postacute care utilization between 2013 and 2018. Exposure: ADRD diagnosis from an acute or postacute care encounter Medicare data source. Main Outcomes and Measures: Enrollment in Medicare Advantage, disenrollment from Medicare Advantage to traditional Medicare, and contract exit (leaving a Medicare Advantage contract for traditional Medicare or a different Medicare Advantage contract). Results: The 32 796 872 Medicare beneficiaries in the cohort had a mean (SD) age of 74.0 (12.5) years and included 18 228 513 females (55.6%). Enrollment in Medicare Advantage among beneficiaries with ADRD increased from 24.7% (95% CI, 24.7%-24.8%) in 2013 to 33.0% (95% CI, 32.9%-33.1%) in 2018, an absolute increase of 8.3 percentage points and a 33.4% relative increase after adjusting for demographic characteristics, comorbid conditions, and utilization and including county fixed effects. Among beneficiaries without ADRD, enrollment in Medicare Advantage increased by 8.2 percentage points from 27.6% (95% CI, 27.6%-27.6%) in 2013 to 35.8% (95% CI, 35.8%-35.8%) in 2018, a 29.7% relative increase over the study period. Beneficiaries with ADRD were 1.4 times as likely to disenroll from their Medicare Advantage contract to traditional Medicare (4.4% vs 3.2% in 2017-2018; P < .001) in adjusted analyses. Regardless of ADRD status, beneficiaries had similar rates of switching to a new Medicare Advantage contract. Differences in contract exit rates were associated with higher rates of disenrollment from Medicare Advantage to traditional Medicare among beneficiaries with ADRD vs those without ADRD (16.3% [95% CI, 16.2%-16.3%] vs 15.1% [95% CI, 15.1%-15.1%]). Beneficiaries with ADRD and dual eligibility for Medicaid enrollment had higher rates of contract exit than those without dual eligibility (19.7% [95% CI, 19.6%-19.7%] vs 14.9% [95% CI, 14.8%-14.9%]), and these differences were even greater than those among beneficiaries without ADRD and with and without dual-eligibility status, respectively (18.3% [95% CI, 18.2%-18.3%] vs 13.8% [95% CI, 13.7%-13.8%]). Conclusions and Relevance: In this cross-sectional study of the Medicare population with acute and postacute care use, beneficiaries with ADRD had increasing enrollment in the Medicare Advantage program, proportional to the growth in overall enrollment, but their disenrollment from Medicare Advantage in the following year remained higher compared with beneficiaries without ADRD. The findings highlight the need to understand the factors associated with higher disenrollment rates and determine whether such rates reflect access or quality challenges for beneficiaries with ADRD.

Provision of evaluation and management visits by nurse practitioners and physician assistants in the USA from 2013 to 2019: cross-sectional time series study.

OBJECTIVE: To examine the proportion of healthcare visits are delivered by nurse practitioners and physician assistants versus physicians and how this has changed over time and by clinical setting, diagnosis, and patient demographics. DESIGN: Cross-sectional time series study. SETTING: National data from the traditional Medicare insurance program in the USA. PARTICIPANTS: Of people using Medicare (ie, those older than 65 years, permanently disabled, and people with end stage renal disease), a 20% random sample was taken. MAIN OUTCOME MEASURES: The proportion of physician, nurse practitioner, and physician assistant visits in the outpatient and skilled nursing facility settings delivered by physicians, nurse practitioners, and physician assistants, and how this proportion varies by type of visit and diagnosis. RESULTS: From 1 January 2013 to 31 December 2019, 276 million visits were included in the sample. The proportion of all visits delivered by nurse practitioners and physician assistants in a year increased from 14.0% (95% confidence interval 14.0% to 14.0%) to 25.6% (25.6% to 25.6%). In 2019, the proportion of visits delivered by a nurse practitioner or physician assistant varied across conditions, ranging from 13.2% for eye disorders and 20.4% for hypertension to 36.7% for anxiety disorders and 41.5% for respiratory infections. Among all patients with at least one visit in 2019, 41.9% had one or more nurse practitioner or physician assistant visits. Compared with patients who had no visits from a nurse practitioner or physician assistant, the likelihood of receiving any care was greatest among patients who were lower income (2.9% greater), rural residents (19.7%), and disabled (5.6%). CONCLUSION: The proportion of visits delivered by nurse practitioners and physician assistants in the USA is increasing rapidly and now accounts for a quarter of all healthcare visits.

Hip fracture surgery performed by cadaveric simulation-trained versus standard-trained orthopaedic trainees: a preliminary multicentre randomized controlled trial.

Aims: To evaluate if, for orthopaedic trainees, additional cadaveric simulation training or standard training alone yields superior radiological and clinical outcomes in patients undergoing dynamic hip screw (DHS) fixation or hemiarthroplasty for hip fracture. Methods: This was a preliminary, pragmatic, multicentre, parallel group randomized controlled trial in nine secondary and tertiary NHS hospitals in England. Researchers were blinded to group allocation. Overall, 40 trainees in the West Midlands were eligible: 33 agreed to take part and were randomized, five withdrew after randomization, 13 were allocated cadaveric training, and 15 were allocated standard training. The intervention was an additional two-day cadaveric simulation course. The control group received standard on-the-job training. Primary outcome was implant position on the postoperative radiograph: tip-apex distance (mm) (DHS) and leg length discrepancy (mm) (hemiarthroplasty). Secondary clinical outcomes were procedure time, length of hospital stay, acute postoperative complication rate, and 12-month mortality. Procedure-specific secondary outcomes were intraoperative radiation dose (for DHS) and postoperative blood transfusion requirement (hemiarthroplasty). Results: Eight female (29%) and 20 male trainees (71%), mean age 29.4 years, performed 317 DHS operations and 243 hemiarthroplasties during ten months of follow-up. Primary analysis was a random effect model with surgeon-level fixed effects of patient condition, patient age, and surgeon experience, with a random intercept for surgeon. Under the intention-to-treat principle, for hemiarthroplasty there was better implant position in favour of cadaveric training, measured by leg length discrepancy ≤ 10 mm (odds ratio (OR) 4.08 (95% confidence interval (CI) 1.17 to 14.22); p = 0.027). There were significantly fewer postoperative blood transfusions required in patients undergoing hemiarthroplasty by cadaveric-trained compared to standard-trained surgeons (OR 6.00 (95% CI 1.83 to 19.69); p = 0.003). For DHS, there was no significant between-group difference in implant position as measured by tip-apex distance ≤ 25 mm (OR 6.47 (95% CI 0.97 to 43.05); p = 0.053). No between-group differences were observed for any secondary clinical outcomes. Conclusion: Trainees randomized to additional cadaveric training performed hip fracture fixation with better implant positioning and fewer postoperative blood transfusions in hemiarthroplasty. This effect, which was previously unknown, may be a consequence of the intervention. Further study is required.

Ankle fracture internal fixation performed by cadaveric simulation-trained versus standard-trained orthopaedic trainees: a preliminary, multicentre randomized controlled trial.

Aims: Ankle fracture fixation is commonly performed by junior trainees. Simulation training using cadavers may shorten the learning curve and result in a technically superior surgical performance. Methods: We undertook a preliminary, pragmatic, single-blinded, multicentre, randomized controlled trial of cadaveric simulation versus standard training. Primary outcome was fracture reduction on postoperative radiographs. Results: Overall, 139 ankle fractures were fixed by 28 postgraduate year three to five trainee surgeons (mean age 29.4 years; 71% males) during ten months' follow-up. Under the intention-to-treat principle, a technically superior fixation was performed by the cadaveric-trained group compared to the standard-trained group, as measured on the first postoperative radiograph against predefined acceptability thresholds. The cadaveric-trained group used a lower intraoperative dose of radiation than the standard-trained group (mean difference 0.011 Gym2, 95% confidence interval 0.003 to 0.019; p = 0.009). There was no difference in procedure time. Conclusion: Trainees randomized to cadaveric training performed better ankle fracture fixations and irradiated patients less during surgery compared to standard-trained trainees. This effect, which was previously unknown, is likely to be a consequence of the intervention. Further study is required.

How All-Payer Claims Databases (APCDs) Can be Used to Examine Changes in Professional Spending: Experience from the Rhode Island APCD.

States are increasingly the focus of health care spending reform efforts given political deadlock at the federal level. Using the Rhode Island All-Payer Claims Database (APCD) from 2016 to 2019, a modified National Uniform Claim Committee (NUCC) provider taxonomy, and the 2021 Restructured BETOS Classification System (RBCS), we evaluate professional spending trends in commercial and Medicaid populations, identify specialties and clinical service categories driving trends, and examine price and volume contributions to spending changes. We found that professional spending from 2016-2019 in Medicaid is increasing faster than professional spending in commercial (5.2% vs. 2.7% annually). We also found that nurse practitioner and physician assistant evaluation and management (E&M), behavioral health services E&M, anesthesia, diagnostic radiology imaging, and orthopedic procedures were among the largest areas of spending increase during the study period in Rhode Island. Three-year trends showed heterogeneity in whether volume or price was primarily responsible for these spending increases.

The Burden and Treatment of Chronic Constipation Among US Nursing Home Residents.

OBJECTIVE: To evaluate the burden of chronic constipation (CC) and the use of drugs to treat constipation (DTC) in 2 complementary data sources. DESIGN: Retrospective cohort study. SETTING AND PARTICIPANTS: US nursing home residents aged ≥65 years with CC. METHODS: We conducted 2 retrospective cohort studies in parallel using (1) 2016 electronic health record (EHR) data from 126 nursing homes and (2) 2014-2016 Medicare claims, each linked with the Minimum Data Set (MDS). CC was defined as (1) the MDS constipation indicator and/or (2) chronic DTC use. We described the prevalence and incidence rate of CC and the use of DTC. RESULTS: In the EHR cohort, we identified 25,739 residents (71.8%) with CC during 2016. Among residents with prevalent CC, 37% received a DTC, with an average duration of use of 19 days per resident-month during follow-up. The most frequently prescribed DTC classes included osmotic (22.6%), stimulant (20.9%), and emollient (17.9%) laxatives. In the Medicare cohort, a total of 245,578 residents (37.5%) had CC. Among residents with prevalent CC, 59% received a DTC and slightly more than half (55%) were prescribed an osmotic laxative. Duration of use was shorter (10 days per resident-month) in the Medicare (vs EHR) cohort. CONCLUSIONS AND IMPLICATIONS: The burden of CC is high among nursing home residents. The differences in the estimates between the EHR and Medicare data confirm the importance of using secondary data sources that include over-the-counter drugs and other treatments unobservable in Medicare Part D claims to assess the burden of CC and DTC use in this population.

Psychosocial interventions and mental health in patients with cardiovascular diseases living in low- and middle-income countries: A systematic review and meta-analysis.

OBJECTIVE: Mental health issues are closely associated with symptoms and outcomes of cardiovascular diseases (CVDs). The magnitude of this problem is alarmingly high in low and middle-income countries (LMICs). This systematic review and meta-analysis aimed to examine the effectiveness of psychosocial interventions on mental health outcomes among patients with CVDs living in LMICs. METHODS: This review includes Randomized controlled trials (RCTs) and quasi-experimental studies conducted on adult patients who had a CVD and/or hypertension and located in LMICs. Studies published in English between 2010 and March, 2021 and which primarily reported mental health outcomes of resilience, self-efficacy, Quality of life (QoL), depression and anxiety were included. Studies were screened, extracted and critically appraised by two independent reviewers. Meta-analysis was conducted for RCTs and narrative summaries were conducted for all other studies. PRISMA guidelines were followed for reporting review methods and findings. RESULTS: 109 studies included in this review reported educational, nursing, behavioral and psychological, spiritual, relaxation, and mindfulness interventions provided by multidisciplinary teams. 14 studies reported self-efficacy, 70 reported QoL, 62 reported one or both of anxiety and depression, and no study was found that reported resilience as an outcome in this population. Pooled analysis showed improvements in self-efficacy and QoL outcomes. The majority of studies showed improvement in outcomes, though the quality of the included studies varied. CONCLUSION: Patients with CVDs in LMICs may experience improved mental health through the use of diverse psychosocial interventions. Evaluations are needed to investigate whether the impact of interventions on mental health are sustained over time.

TRIPLE C reporting principles for case study evaluations of the role of context in complex interventions.

BACKGROUND: Guidance and reporting principles such as CONSORT (for randomised trials) and PRISMA (for systematic reviews) have greatly improved the reporting, discoverability, transparency and consistency of published research. We sought to develop similar guidance for case study evaluations undertaken to explore the influence of context on the processes and outcomes of complex interventions. METHODS: A range of experts were recruited to an online Delphi panel, sampling for maximum diversity in disciplines (e.g. public health, health services research, organisational studies), settings (e.g. country), and sectors (e.g. academic, policy, third sector). To inform panel deliberations, we prepared background materials based on: [a] a systematic meta-narrative review of empirical and methodological literatures on case study, context and complex interventions; [b] the collective experience of a network of health systems and public health researchers; and [c] the established RAMESES II standards (which cover one kind of case study). We developed a list of topics and issues based on these sources and encouraged panel members to provide free text comments. Their feedback informed development of a set of items in the form of questions for potential inclusion in the reporting principles. We circulated these by email, asking panel members to rank each potential item twice (for relevance and validity) on a 7-point Likert scale. This sequence was repeated twice. RESULTS: We recruited 51 panel members from 50 organisations across 12 countries, who brought experience of a range of case study research methods and applications. 26 completed all three Delphi rounds, reaching over 80% consensus on 16 items covering title, abstract, definitions of terms, philosophical assumptions, research question(s), rationale, how context and complexity relates to the intervention, ethical approval, empirical methods, findings, use of theory, generalisability and transferability, researcher perspective and influence, conclusions and recommendations, and funding and conflicts of interest. CONCLUSION: The 'Triple C' (Case study, Context, Complex interventions) reporting principles recognise that case studies are undertaken in different ways for different purposes and based on different philosophical assumptions. They are designed to be enabling rather than prescriptive, and to make case study evaluation reporting on context and complex health interventions more comprehensive, accessible and useable.

Comparing ambulatory commercial spending in Rhode Island and Massachusetts, 2016-2019.

OBJECTIVE: To evaluate trends and drivers of commercial ambulatory spending and price variation. DATA SOURCES AND STUDY SETTING: Commercial claims data from the Massachusetts and Rhode Island All-Payer Claims Databases from 2016 to 2019. STUDY DESIGN: Observational study of spending in major ambulatory care settings. We calculated per member per year spending, average price, and utilization rates to consider drivers of spending, and constructed site-specific price indices to evaluate price variation. DATA COLLECTION/EXTRACTION METHODS: We analyzed commercial claims data from All-Payer Claims Databases in the two states. PRINCIPAL FINDINGS: Ambulatory spending levels in Massachusetts were 38.0% higher than those in Rhode Island in 2019. Overall utilization rates were similar, but Massachusetts had a 6.2 percentage point higher share of visits occurring in hospital outpatient departments (HOPD). Average prices were 31.5% higher in Massachusetts in 2016 and 36.4% higher in 2019. We observed extensive price variation in both states across both office and HOPD settings. CONCLUSIONS: States seeking to address increases in health care spending, including those with cost growth benchmarks and rate review policies, should consider additional interventions that mitigate market failures in the establishment of commercial health care prices.

Assessment of a Price Index for Hospital Outpatient Department Services Using Commercial Claims Data in Massachusetts.

This cross-sectional study assesses a market basket price index to evaluate hospital outpatient department price levels and growth.

Effect of sterile vs clean gloves for cervical checks in labor on maternal infection at term: a randomized trial.

BACKGROUND: Intrapartum infection usually warrants immediate delivery and impacts 5-12% of term pregnancies, with the most commonly identified pathogenic organism being of the Ureaplasma genus. When performing cervical examinations during labor, providers in the United States commonly use sterile gloves, although there are no data currently to support that this practice reduces rates of infection. Furthermore, in nearly all other settings of Gynecologic care, aside from surgery in an operating room, nonsterile gloves are used. Even though the uterus could be sterile in normal pregnancies, the provider performing the cervical examination must traverse the milieu of vaginal bacteria in order to reach the cervix to perform the exam, introducing vaginal microbiota into the uterus regardless of the type of glove used. This prospective randomized controlled study examines whether the type of glove used (sterile vs clean) impacts the rates of intrapartum infection in patients receiving cervical examinations during labor or induction of labor at term.. OBJECTIVE: This study aimed to evaluate if the glove type (sterile vs clean) used for cervical examinations during labor affects the rates of intrapartum and postpartum infection. STUDY DESIGN: This randomized controlled trial assigned eligible and consenting participants to receive cervical examinations during labor with either sterile powder-free polyvinyl chloride examination gloves (current routine practice, control group) or clean powder-free nitrile examination gloves (nonsterile, experimental group). The primary outcome was rates of intrapartum infection (chorioamnionitis). Sample size calculations estimated that 300 participants would be needed with a rate of infection of 10% in the control group and 20% in the experimental group to demonstrate difference between the groups; however, the rates of infection were much lower than expected, at 5.4% and 4.4% in the sterile and clean glove group, respectively. At this point, it was determined futile to continue the study because a sample size of >29,000 participants would be needed, which would not be achievable at a single tertiary care referral center with approximately 3500 deliveries per year. The study was approved by the Eastern Virginia Medical School Institutional Review Board (IRB 21-09-FB-0206), and was registered at ClinicalTrials.gov (identifier NCT05603624; https://clinicaltrials.gov/ct2/show/NCT05603624). RESULTS: A total of 163 participants with singleton pregnancies completed the study; 74 (45%) were randomized to the sterile glove group, and 89 (55%) were randomized to the clean glove group. In the sterile glove group, 4 (5.4%) developed intrapartum infection (chorioamnionitis) and 1 (1.3%) developed postpartum infection (endometritis). In the clean glove group, 4 (4.4%) developed intrapartum infection and 2 (2.2%) developed postpartum infection. There was no significant difference in rates of intrapartum infection (P=1.0) or postpartum infection (P=1.0), or combined rates of infection (including both chorioamnionitis and endometritis; P=.99) between the sterile and the clean glove group. When comparing the participants from both groups who had any intrapartum or postpartum infection (n=11) with those who had no infection (n=152), the former were more likely to be nulliparous (P=.01), have lower gravidity (P<.01) and parity (P<.01), have longer times from first cervical examination to delivery (P=.02), have longer times from rupture of membranes to delivery (P=.0001), undergo cesarean delivery (P=.0002), and experience postpartum hemorrhage (P=.001). Although participants who were in labor for a longer time also likely had more cervical examinations, these data could suggest that duration of labor (P=.02) is more closely associated with infectious morbidity compared with the number of cervical examinations (P=.15). CONCLUSION: Using clean gloves for cervical examinations during labor is unlikely to increase risk of infection, and could reduce cost by up to 92.4% at our institution, saving over $25,000 annually.

Transitions in care between hospital and community settings for individuals with a substance use disorder: A systematic review.

BACKGROUND AND AIMS: Individuals with a substance use disorder (SUD) have high rates of hospital service utilization including emergency department (ED) presentations and hospital admissions. Acute care settings offer a critical opportunity to engage individuals in addiction care and improve health outcomes especially given that the period of transition from hospital to community is challenging. This review summarizes literature on interventions for optimizing transitions in care from hospital to community for individuals with a SUD. METHODS: The literature search focused on key terms associated with transitions in care and SUD. The search was conducted on three databases: MEDLINE, CINAHL, and PsychInfo. Eligible studies evaluated interventions acting prior to or during transitions in care from hospital to community and reported post-discharge engagement in specialized addiction care and/or return to hospital and were published since 2010. RESULTS: Title and abstract screening were conducted for 2337 records. Overall, 31 studies met inclusion criteria, including 7 randomized controlled trials and 24 quasi-experimental designs which focused on opioid use (n = 8), alcohol use (n = 5), or polysubstance use (n = 18). Interventions included pharmacotherapy initiation (n = 7), addiction consult services (n = 9), protocol implementation (n = 3), screening, brief intervention, and referral to treatment (n = 2), patient navigation (n = 4), case management (n = 1), and recovery coaching (n = 3). CONCLUSIONS: Both pharmacologic and psychosocial interventions implemented around transitions from acute to community care settings can improve engagement in care and reduce hospital readmission and ED presentations. Future research should focus on long-term health and social outcomes to improve quality of care for individuals with a SUD.

Assessing technical skill in ankle fracture surgery from the postoperative radiograph : pilot development and validation of a final product analysis core outcome set.

AIMS: To identify a core outcome set of postoperative radiographic measurements to assess technical skill in ankle fracture open reduction internal fixation (ORIF), and to validate these against Van der Vleuten's criteria for effective assessment. METHODS: An e-Delphi exercise was undertaken at a major trauma centre (n = 39) to identify relevant parameters. Feasibility was tested by two authors. Reliability and validity was tested using postoperative radiographs of ankle fracture operations performed by trainees enrolled in an educational trial (IRCTN 20431944). To determine construct validity, trainees were divided into novice (performed < ten cases at baseline) and intermediate groups (performed ≥ ten cases at baseline). To assess concurrent validity, the procedure-based assessment (PBA) was considered the gold standard. The inter-rater and intrarater reliability was tested using a randomly selected subset of 25 cases. RESULTS: Overall, 235 ankle ORIFs were performed by 24 postgraduate year three to five trainees during ten months at nine NHS hospitals in England, UK. Overall, 42 PBAs were completed. The e-Delphi panel identified five 'final product analysis' parameters and defined acceptability thresholds: medial clear space (MCS); medial malleolar displacement (MMD); lateral malleolar displacement (LMD); tibiofibular clear space (TFCS) (all in mm); and talocrural angle (TCA) in degrees. Face validity, content validity, and feasibility were excellent. PBA global rating scale scores in this population showed excellent construct validity as continuous (p < 0.001) and categorical (p = 0.001) variables. Concurrent validity of all metrics was poor against PBA score. Intrarater reliability was substantial for all parameters (intraclass correlation coefficient (ICC) > 0.8), and inter-rater reliability was substantial for LMD, MMD, TCA, and moderate (ICC 0.61 to 0.80) for MCS and TFCS. Assessment was time efficient compared to PBA. CONCLUSION: Assessment of technical skill in ankle fracture surgery using the first postoperative radiograph satisfies the tested Van der Vleuten's utility criteria for effective assessment. 'Final product analysis' assessment may be useful to assess skill transfer in the simulation-based research setting. Cite this article: Bone Jt Open 2022;3(6):502-509.

Frequency Of Indirect Billing To Medicare For Nurse Practitioner And Physician Assistant Office Visits.

Nurse practitioners (NPs) and physician assistants (PAs) represent a growing share of the health care workforce, but much of the care they provide cannot be observed in claims data because of indirect (or "incident to") billing, a practice in which visits provided by an NP or PA are billed by a supervising physician. If NPs and PAs bill directly for a visit, Medicare and many private payers pay 85 percent of what is paid to a physician for the same service. Some policy makers have proposed eliminating indirect billing, but the possible impact of such a change is unknown. Using a novel approach that relies on prescriptions to identify indirectly billed visits, we estimated that the number of all NP or PA visits in fee-for-service Medicare data billed indirectly was 10.9 million in 2010 and 30.6 million in 2018. Indirect billing was more common in states with laws restricting NPs' scope of practice. Eliminating indirect billing would have saved Medicare roughly $194 million in 2018, with the greatest decrease in revenue seen among smaller primary care practices, which are more likely to use this form of billing.

Freestyle Deliberate Practice Cadaveric Hand Surgery Simulation Training for Orthopedic Residents: Cohort Study.

BACKGROUND: Cadaveric simulation training may be part of the solution to reduced quantity and quality of operative surgical training in the modern climate. Cadaveric simulation allows the early part of the surgical learning curve to be moved away from patients into the laboratory, and there is a growing body of evidence that it may be an effective adjunct to traditional methods for training surgical residents. It is typically resource constrained as cadaveric material and facilities are expensive. Therefore, there is a need to be sure that any given cadaveric training intervention is maximally impactful. Deliberate practice (DP) theory as applied to cadaveric simulation training might enhance the educational impact. OBJECTIVE: The objectives of this study were (1) to assess the impact of a freestyle DP cadaveric hand surgery simulation training intervention on self-reported operative confidence for 3 different procedures and (2) to assess the subjective transfer validity, perceived educational value, and simulation fidelity of the training. METHODS: This study used validated questionnaires to assess the training impact on a cohort of orthopedic residents. The freestyle course structure allowed the residents to prospectively define personalized learning objectives, which were then addressed through DP. The study was conducted at Keele Anatomy and Surgical Training Centre, a medical school with an integrated cadaveric training laboratory in England, United Kingdom. A total of 22 orthopedic surgery residents of postgraduate year (PGY) 5-10 from 3 regional surgical training programs participated in this study. RESULTS: The most junior (PGY 5-6) residents had the greatest self-reported confidence gains after training for the 3 procedures (distal radius open reduction internal fixation, flexor tendon repair, ulnar shortening osteotomy), and these gains diminished with resident seniority. The confidence gains were proportional to the perceived procedural complexity, with the most complex procedure having the lowest pretraining confidence score across all experience levels, and the greatest confidence increase in posttraining. Midstage (PGY 7-8) residents reported receiving the highest level of educational benefit from the training but perceived the simulation to be less realistic, compared to either the junior or senior residents. The most senior residents (PGY 9-10) reported the greatest satisfaction with the self-directed, freestyle nature of the training. All groups reported that they were extremely likely to transfer their technical skill gains to their workplace, that they would change their current practice based on these skills, and that their patients would benefit as a result of their having undertaken the training. CONCLUSIONS: Freestyle, resident-directed cadaveric simulation provides optimum DP conditions whereby residents can target their individualized learning needs. By receiving intensive, directed feedback from faculty, they can make rapid skill gains in a short amount of time. Subjective transfer validity potential from the training was very high, and objective, quantitative evidence of this is required from future work.
