Buprenorphine prescribing and treatment accessibility in response to regulation changes due to the COVID-19 public health emergency.

BACKGROUND: In 2021, over 80,000 fatal overdoses occurred in the United States. Since 2020, the federal government has enacted multiple regulatory changes around buprenorphine prescribing for opioid use disorder (OUD) to increase access to buprenorphine. This study aims to explore trends in buprenorphine treatment initiation pre- and post-public health emergency to evaluate changes in the context of X-waiver relaxations and telehealth allowances. METHODS: In a cross-sectional study, all RI residents who filled a buprenorphine prescription at a pharmacy in Rhode Island (RI), Massachusetts, and Connecticut between January 2017 and December 2023 were obtained from the RI Prescription Drug Monitoring Program (PDMP). The study excluded buprenorphine products not approved for OUD treatment from the analysis. Identified individuals had initiated buprenorphine for OUD during the study period if they did not have a prior prescription or if they had >30 days without buprenorphine exposure between their prescriptions. Spearman's rank correlation tests were used to identify significant associations between outcomes and regulation changes. RESULTS: The average number of patients dispensed buprenorphine did not significantly change over the study period, however the average number of initiates significantly decreased (ρ = -0.38255, p = .0003). The average number of providers prescribing CII-CV substances in RI has increased 3.4 % over the study period. The average percentage of prescribers in the PDMP prescribing buprenorphine for OUD doubled (ρ = 0.96075, p < .0001). CONCLUSION: Though efforts have been made to increase buprenorphine initiation, buprenorphine initiates remain well below pre-PHE levels. Efforts must continue to eliminate existing barriers to treatment and improve access to individuals seeking treatment.

Compassion and equity-focused clinical genomics training for health professional learners.

There remains an urgent need for expanded genomics training in undergraduate medical education, especially as genetic and genomic assessments become increasingly important in primary care and routine clinical practice across specialties. Physician trainees continue to report feeling poorly prepared to provide effective consultation or interpretation of genomic test results. Here we report on the development, pilot implementation, and evaluation of an elective offering for pre-clinical medical students called the Sanford Precision Health Scholars Immersive Learning Experience (PHS), which was designed leveraging genetic counseling expertise as one means to address this need. This 9-week course, piloted in Fall 2021 at UC San Diego, afforded students the opportunity to build technical skills and competencies in clinical genomics while identifying, addressing, and engaging with pervasive health disparities in genomics. Interactive exercises focused students' learning on strategies for empathic and compassionate patient interactions while supporting the application of concepts and knowledge to future practice. Upon completion of the course, participants reported increases in confidence related to skills required for clinical genomics practice. Drawing on learnings from this pilot implementation, recommendations for refining the program include deepening pedagogical engagement with ethical issues, expanding the offering to trainees across health professions, including pharmacy students, and incorporating an optional experiential learning component. Educational offerings, like PHS, that are designed with the input of genetic counseling expertise may ease pressures on the genetic counseling profession by building a more genomic-literate healthcare workforce that can better support efforts to expand access for patients.

Socioeconomic status and healthcare utilization disparities among children with epilepsy in the United States: Results from a nationally representative sample.

Epilepsy affects 1% of the US population. Healthcare disparities are well-studied among adults with epilepsy but less so among children. We examined whether children with epilepsy (1) have lower income than or (2) utilize the emergency department (ED) differently from children without epilepsy, and (3) if income moderates ED utilization. Data from the 2016-2019 National Survey of Children's Health were used to identify children with active "epilepsy or seizure disorder". Children with versus without epilepsy were compared. Income and ED visits were modeled with logistic and Poisson regressions. This analysis included 131,326 children; 835 were diagnosed with epilepsy. Estimated population prevalence of epilepsy was 0.6%. Children from higher-income-households were less likely to have epilepsy (aOR: 0.7). Children with epilepsy were more likely to visit EDs (aOR = 10.2), see healthcare professionals (aOR: 2.7), and receive care from specialists (aOR: 10.3). Income moderated the relationship between having epilepsy and ED visits. 7.7% of children with epilepsy did not receive needed healthcare. Some barriers were acquiring appointments (aOR: 3.9) and transportation (aOR: 4.7). In conclusion, children with epilepsy were more likely than children without epilepsy to live in lower-income-households, visit EDs, see healthcare professionals, and not receive needed healthcare. Barrier-specific policy interventions may improve medical access for children with epilepsy.

Disparities in time to prostate cancer treatment initiation before and after the Affordable Care Act.

BACKGROUND: Delayed access to care may contribute to disparities in prostate cancer (PCa). The Affordable Care Act (ACA) aimed at increasing access and reducing healthcare disparities, but its impact on timely treatment initiation for PCa men is unknown. METHODS: Men with intermediate- and high-risk PCa diagnosed 2010-2016 and treated with curative surgery or radiotherapy were identified in the National Cancer Database. Multivariable logistic regression modeled the effect of race and insurance type on treatment delay >180 days after diagnosis. Cochran-Armitage test measured annual trends in delays, and joinpoint regression assessed if 2014, the year the ACA became fully operationalized, was significant for inflection in crude rates of major delays. RESULTS: Of 422,506 eligible men, 18,720 (4.4%) experienced >180-day delay in treatment initiation. Compared to White patients, Black (OR 1.79, 95% CI 1.72-1.87, p < 0.001) and Hispanic (OR 1.37, 95% CI 1.28-1.48, p < 0.001) patients had higher odds of delay. Compared to uninsured, those with Medicaid had no difference in odds of delay (OR 0.94, 95% CI 0.84-1.06, p = 0.31), while those with private insurance (OR 0.57, 95% CI 0.52-0.63, p < 0.001) or Medicare (OR 0.64, 95% CI 0.58-0.70, p < 0.001) had lower odds of delay. Mean time to treatment significantly increased from 2010 to 2016 across all racial/ethnic groups (trend p < 0.001); 2014 was associated with a significant inflection for increase in rates of major delays. CONCLUSIONS: Non-White and Medicaid-insured men with localized PCa are at risk of treatment delays in the United States. Treatment delays have been consistently rising, particularly after implementation of the ACA.

Trends in Initiate Pediatric Opioid Prescriptions in Rhode Island: 2017-2021.

OBJECTIVE: To analyze recent trends in initiate pediatric opioid prescriptions dispensed in Rhode Island. METHODS: All Rhode Island residents aged 0-17 years with an initiate opioid prescription dispensed between January 1, 2017 and December 31, 2021 were obtained from the Rhode Island Prescription Drug Monitoring Program. Analyses were conducted to investigate trends related to patient demographics, prescription characteristics, diagnosis codes, and prescriber type. RESULTS: From 2017-2021, there was a decrease in the number of unique pediatric patients dispensed an initiate prescription, the number of initiate pediatric opioid prescriptions, and the initiate prescription dosage. Initiate opioid prescriptions were primarily related to dental-related diagnoses, and dentists and oral and maxillofacial (OMF) surgeons comprised the largest category of prescriber type. CONCLUSION: Initiate pediatric opioid prescriptions have decreased in Rhode Island in recent years. However, there remain opportunities to educate prescribers on reducing opioid exposure to vulnerable populations, including the use of alternate analgesics.

Economic impact of nature-based tourism.

Protected areas (PAs) can help address biodiversity loss by promoting conservation while fostering economic development through sustainable tourism. Nature-based tourism can generate economic benefits for communities in and around PAs; however, its impacts do not lend themselves to conventional impact evaluation tools. We utilize a Monte Carlo simulation approach with econometric estimations using microdata to estimate the full economic impact of nature-based tourism on the economies surrounding three terrestrial and two marine PAs. Simulations suggest that nature-based tourism creates significant economic benefits for communities around PAs, including the poorest households, and many of these benefits are indirect, via income and production spillovers. An additional tourist increases annual real income in communities near the PAs by US$169-$2,400, significantly more than the average tourist's expenditure. Conversely, lost tourism due to the COVID-19 pandemic and economic costs of human-wildlife conflict have disproportionately large negative impacts on local incomes.

Cost-effectiveness analysis of tumor molecular testing in stage III endometrial cancer.

BACKGROUND: Standard of care for adjuvant treatment of stage III endometrial cancer includes chemotherapy and radiation. In addition to stage, tumor molecular profiles may predict treatment outcomes, and prospective clinical trials are ongoing. However, tumor molecular testing is costly and time-consuming. Our objective was to evaluate the cost-effectiveness of tumor molecular testing in stage III endometrial cancer. METHODS: A Markov decision model compared two strategies for stage III endometrial cancer: Tumor Molecular Testing (TMT) versus No TMT. TMT included sequential POLE next generation sequencing, mismatch repair immunohistochemistry (IHC), and p53 IHC. POLE-mutated patients were assigned to adjuvant radiation therapy; all others including controls were assigned to adjuvant chemoradiation. First recurrences were treated with 6 cycles of carboplatin and paclitaxel. Second recurrences were treated with pembrolizumab alone for mismatch repair deficient patients and both pembrolizumab and lenvatinib for other patients. Sensitivity analyses were performed to test model robustness. RESULTS: Compared to No TMT, TMT was cost saving with equivalent effectiveness. On one-way sensitivity analysis, TMT remained cost saving over all parameter ranges. TMT was also favored on probabilistic sensitivity analysis in 80% of iterations at a willingness-to-pay threshold of $100,000/quality adjusted life-year (QALY) gained. However, when TMT was compared to mismatch repair IHC alone, TMT cost $182,798/QALY gained. CONCLUSIONS: In this model of patients with stage III endometrial cancer, TMT was cost saving compared to No TMT. However, when compared to mismatch repair IHC alone, TMT was economically unfavorable.

Cost-effectiveness of invasive monitoring strategies in epilepsy surgery.

OBJECTIVE: Drug-resistant epilepsy occurs in up to 40% of patients with epilepsy who may be considered for epilepsy surgery. For drug-resistant focal epilepsy, up to 50% of patients require invasive monitoring prior to surgery. Of the most common invasive monitoring strategies (subdural electrodes [SDEs] and stereo-electroencephalography [sEEG]), the most cost-effective strategy is unknown despite substantial differences in morbidity profiles. METHODS: Using data collected from an internationally representative sample published in available systematic reviews and meta-analyses, this economic evaluation study employs a decision analysis model to simulate the risks and benefits of SDE and sEEG invasive monitoring strategies. In this model, patients faced differing risks of morbidity, mortality, resection, and seizure freedom depending on which invasive monitoring strategy they underwent. A range of cost values was obtained from a recently published single-center cost-utility analysis. The model considers a base case simulation of a characteristic patient with drug-resistant epilepsy using clinical parameters obtained from systematic reviews of invasive monitoring available in the literature. The main outcome measure was the probability of a positive outcome after invasive monitoring, which was defined as improvement in seizures without a complication. Cost-effectiveness was measured using an incremental cost-effectiveness ratio (ICER). RESULTS: Invasive monitoring with sEEG had an increased cost of $274 and increased probability of effectiveness of 0.02 compared with SDEs, yielding an ICER of $12,630 per positive outcome obtained. Sensitivity analyses varied parameters widely and revealed consistent model results across the range of clinical parameters reported in the literature. One-way sensitivity analyses revealed that invasive monitoring strategy costs were the most influential parameter for model outcome. CONCLUSIONS: In this analysis, based on available observational data and estimates of complication costs, invasive monitoring with either SDEs or sEEG was nearly equivalent in terms of cost-effectiveness.

Aided recall of The Real Cost e-cigarette prevention advertisements among a nationally representative sample of adolescents.

E-cigarette use among youth remains a significant public health concern. In 2018, The Real Cost campaign began disseminating messages about the harms of vaping, primarily using digital media. We sought to determine the prevalence of aided recall of The Real Cost e-cigarette prevention ads and identify potential differences by participant characteristics. Participants were a nationally representative sample of adolescents living in United States (US) households recruited by the National Opinion Research Center (NORC) at the University of Chicago's AmeriSpeak panel in September and October of 2020. A total of 623 adolescents completed the survey. Analyses were weighted to represent the distribution of youth in the US, and effect sizes for individual characteristics were estimated using an adjusted marginalized two-part model. Seventy-one percent of adolescents recalled at least one of the five The Real Cost e-cigarette prevention ads, with individual ad recall ranging from a low of 38.8% (for Magic) to a high of 50.1% (for Narrative). Adjusted estimates of aided recall identified significantly higher recall among Black adolescents and those that used social media at medium or high frequencies (p < 0.05). Results support ongoing efforts by the FDA to reach youth with e-cigarette prevention messages using primarily digital media.

Trends in Acromioplasty Utilization During Arthroscopic Rotator Cuff Repair: An Epidemiological Study of 139,586 Patients.

INTRODUCTION: Acromioplasty remains very common during rotator cuff repair (RCR) despite limited evidence of clinical efficacy. This study observed the incidence of acromioplasty from 2010 to 2018 in Texas using a publicly available database. METHODS: A total of 139,586 records were analyzed from the Texas Healthcare Information Collection database ranging from 2010 to 2018. These cases were divided into those with and without acromioplasty (N = 107,427 and N = 32,159, respectively). Acromioplasty use was standardized as the number of acromioplasties per RCR (acromioplasty rate). Two subgroup analyses were conducted: surgical institution type and payor status. RESULTS: In 2010, acromioplasty occurred in 84% of all RCR cases with nearly continuous decline to 74% by 2018 (P < 0.001). All subgroups followed this pattern except teaching hospitals which displayed insignificant change from 2010 to 2018 (P = 0.99). The odds of receiving acromioplasty in patients with neither Medicare nor Medicaid was higher than those with Medicare or Medicaid coverage (odds ratio = 1.36, P < 0.001). DISCUSSION: Overall acromioplasty rates decreased modestly, but markedly, beginning in 2012. Despite this small decrease in acromioplasty rate, it remains a commonly performed procedure in conjunction with RCR. Both the academic status of the surgical facility and the payor status of the patient affect the acromioplasty rate.

Eliminating the Low-Prevalence Effect in Visual Search With a Remarkably Simple Strategy.

The low-prevalence effect in visual search occurs when rare targets are missed at a disproportionately high rate. This effect has enormous significance for health and public safety and has proven resistant to intervention. In three experiments (Ns = 41, 40, and 44 adults), we documented a dramatic reduction of the effect using a simple cognitive strategy requiring no training. Instead of asking participants to search for the presence or absence of a target, as is typically done in visual search tasks, we asked participants to engage in "similarity search"-to identify the display element most similar to a target on every trial, regardless of whether a target was present. When participants received normal search instructions, we observed strong low-prevalence effects. When participants used similarity search, we failed to detect the low-prevalence effect under identical visual conditions across three experiments.

Metal(loid) accumulation in the leaves of the grey mangrove (Avicennia marina): Assessment of robust sampling requirements and potential use as a bioindicator.

This study assessed the appropriate sampling design required for quantifying variability in metal accumulation in the leaf tissues of A. marina, a dominant mangrove inhabiting Australian estuaries, by applying a hierarchical nested sampling design to sample mangroves at various levels of biological and spatial hierarchies (leaf, branch, tree, site). It was revealed that most variation in metal accumulation occurred among trees and branches, with insignificant variation between sites and among leaves. We also examined the accumulation of metal (loid)s in the leaf tissues collected from six locations across the Georges River estuary in southern Sydney, which differ in metal contamination history. Prospect Creek and Salt Pan Creek were the most contaminated locations, which exceeded sediment quality guideline values for Cu (66.71 ± 2.18 µg/g), Zn (317.14 ± 46.14 µg/g) and Pb (81.02 ± 2.79 µg/g). All metal(loid) concentrations in leaf tissues were much lower than their concentrations in sediment, but essential metals exhibited greater mobility. Out of 10 metal(loid)s, Mn, Co and Pb in leaves showed linear relationships (R2 = 0.28-0.47) with sediment, indicating that mangrove leaves may be used as a bioindicator of environmental loads for these metals.

One-year cost-effectiveness of callosotomy vs vagus nerve stimulation for drug-resistant seizures in Lennox-Gastaut Syndrome: A decision analytic model.

OBJECTIVE: Palliative epilepsy surgery via corpus callosotomy (CC) or vagus nerve stimulation (VNS) is commonly employed for drug-resistant seizures in Lennox-Gastaut Syndrome (LGS). VNS is less effective at reducing seizures but has fewer adverse events, CC is more effective for seizure control, particularly atonic seizures, but can be associated with serious adverse events, and yet their relative cost-effectiveness remains unknown. METHODS: To determine which option is most cost-effective, a decision analytic model was developed to evaluate the risks and benefits of CC and VNS at 1 year based on costs in the United States. Our primary outcome measure was positive seizure outcomes, defined as >50% seizure reduction without procedural complications. RESULTS: CC had a 15% greater likelihood of a positive seizure outcome, but per patient costs were $68 147 more than VNS, or $451 952 per positive seizure outcome gained. One-way sensitivity analyses demonstrate that probabilities of seizure freedom or reduction by VNS or CC and CC cost were most influential on results. When considering atonic seizures, CC had a 27% greater positive outcome likelihood than VNS, the same incremental cost, and cost $250 556 per positive seizure outcome gained. SIGNIFICANCE: This exploratory model suggests that VNS is more cost-effective relative to CC at 1 year.

Design and assessment of a penile fracture simulation model.

OBJECTIVE: To design and assess a novel penile fracture simulation model for teaching penile fracture repair. METHODS: We used a validated circumcision simulator to create a model. Foreskin for a circumcision was divided into two halves. A transverse slit ("simulated fracture") was created on one part of the first half of the foreskin (mimicking "tunica") and was applied over the penile model. A red jelly tablet ("clot") was placed underneath the cut. A second full-length of foreskin was applied over it to cover the defect. The model was assessed by participants and expert faculty at the Urology Simulation Boot Camp. Evaluation was performed using a 5-point Likert Scale questionnaire. Data was analysed using Microsoft Excel and IBM SPSS Statistics V25. The intra-class correlation was calculated using a "One-way random model". RESULTS: Twenty-two urology trainees and four experts participated in the evaluation. The majority of trainees strongly agreed (59%, n = 13) the model is useful for training with experts similarly agreeing in 75% of cases. The appearance of penile fracture was considered good by both trainees (68%, n = 14) and faculty (75%). Overall, the ability of the model to represent a realistic simulation of the task was considered excellent by 23% of participants and good by 64%. Personal confidence after simulation in managing a similar situation was considered high among trainees. The main difficulties reported were related to fascial planes and urethra. CONCLUSION: This is the first simulation model for penile fracture repair and has demonstrated face validity at a national urology bootcamp.

Insufficient Access: Naloxone Availability to Laypeople in Arizona and Indiana, 2018.

OBJECTIVES: To understand naloxone availability to laypeople in Arizona (Ariz.) and Indiana (Ind.). METHODS: Multi-source search conducted from May-December 2018 identifi ed the extent of naloxone availability to laypeople. Internet searches, email follow up, and phone interviews occurred with registered naloxone providers. RESULTS: Th ere were 89 naloxone providers in each state. Laypeople were ineligible for access for over half of registered naloxone providers in Ariz. (60.7%) and Ind. (55.1%). Naloxone access was mostly (67.4%) passive in Ariz. but was actively distributed in Ind. (67.4%). Syringe service programs (SSP) were the most frequently identifi ed providers of naloxone to laypeople in Ariz. (20.0%). In Ind., local health departments were most frequently identifi ed as layperson naloxone providers (75.0%). CONCLUSIONS: Less than half of registered naloxone providers allowed layperson access in Arizona and Indiana. Th e lack of layperson access highlights the need to review organization practice and state policy to ensure increased layperson access.

Coincident rapid expansion of two SARS-CoV-2 lineages with enhanced infectivity in Nigeria.

The emergence of new SARS-CoV-2 variants with enhanced transmissibility or decreased susceptibility to immune responses is a major threat to global efforts to end the coronavirus disease 2019 (COVID-19) pandemic. Disparities in viral genomic surveillance capabilities and efforts have resulted in gaps in our understanding of the viral population dynamics across the globe. Nigeria, despite having the largest population of any nation in Africa, has had relatively little SARS-CoV-2 sequence data made publicly available. Here we report the whole-genome sequences of 74 SARS-CoV-2 isolates collected from individuals in Oyo State, Nigeria in January 2021. Most isolates belonged to either the B.1.1.7 Alpha "variant of concern" or the B.1.525 Eta lineage, which is currently considered a "variant of interest" containing multiple spike protein mutations previously associated with enhanced transmissibility and possible immune escape. Nigeria has the highest reported frequency of the B.1.525 lineage globally with phylogenetic characteristics consistent with a recent monophyletic origin and rapid expansion. Spike protein from the B.1.525 lineage displayed both increased infectivity and decreased neutralization by convalescent sera compared to Spike proteins from other clades. These results, along with indications that the virus is outpacing the B.1.1.7 lineage in Nigeria, suggest that the B.1.525 lineage represents another "variant of concern" and further underline the importance of genomic surveillance in undersampled regions across the globe.

Is outpatient shoulder arthroplasty safe in patients aged ≥65 years? A comparison of readmissions and complications in inpatient and outpatient settings.

BACKGROUND: Recent studies indicate that outpatient total shoulder arthroplasty (TSA) is cost-effective and may have a low complication rate similar to inpatient TSA. However, existing studies have included younger patient cohorts who typically possess fewer medical comorbidities. Patients aged ≥65 years are commonly enrolled in Medicare, which has traditionally designated TSA as an inpatient-only procedure. The purpose of this study was to compare surgical complication rates and 90-day readmission rates between inpatient and outpatient TSA performed in adults aged ≥65 years. METHODS: Medical records for all patients aged ≥65 years who underwent primary anatomic or reverse TSA by a single surgeon from July 2015 to May 2020 were reviewed. Patients were preselected for outpatient or inpatient surgery based on lack of significant cardiopulmonary comorbidities and patient preference. Demographics, body mass index (BMI), and American Society of Anesthesiologists (ASA) scores were collected in addition to emergency department (ED) visits and readmissions within 90 days of the index surgery. Relationships among frequency and types of complications and surgical setting (inpatients vs. outpatient) were assessed. Complication rates and demographic variables between inpatient and outpatient procedures were compared. Logistic regressions were performed to account for interacting predictor variables on the odds of having complications. RESULTS: A total of 145 shoulders (138 patients; 95 male, 43 female) were included in the analysis, of which 98 received inpatient TSA and 47 received outpatient TSA. Average age was 75.5 ± 7.2 for inpatient TSA and 70.5 ± 4.5 for outpatient TSA (P < .001). Patient age (P < .001), ASA score ≥3 (P < .001), and reverse TSA (P = .002) were significantly positively correlated with receiving inpatient surgery. There were 16 complications (16.3%) in the inpatient group and 9 complications (19.1%) in the outpatient group (P = .648). There were no significant differences in the frequency of postoperative complications, return to the ED, or reoperations between inpatient and outpatient procedures (P > .05). Each 1-year increase in age increased the predicted odds of having a surgical complication by 14% (odds ratio = 1.14; P = .021), irrespective of surgical setting. Those who underwent inpatient TSA had a significantly higher frequency of 90-day readmission (inpatient=16, outpatient=1; P = .034). CONCLUSIONS: Postoperative complications and ED returns were not significantly different between inpatient and outpatient TSA. Each 1-year increase in age increased the odds of postoperative surgical complications by 14%, regardless of surgical setting. Outpatient TSA was found to be safe for appropriately selected patients aged ≥65 years, and re-evaluation of TSA as an inpatient-only procedure should be considered.
