Level 4 seizure monitoring unit admissions are associated with reduced long-term health care costs.

This study was undertaken to determine whether admission to dedicated seizure monitoring units (SMUs) result in reduced health care use (HCU). This was a retrospective open cohort study covering the years 2010-2018 of patients residing in Alberta, Canada, who were referred to the Calgary Comprehensive Epilepsy Program and admitted to a level 4 SMU. Patients were required to have ≥3 years pre- and postadmission follow-up. The outcome was the change in trajectory of composite HCU (primary care, specialist outpatient visits, emergency department visits, and hospitalizations) for the 3 years prior to and 3 years following SMU admission using the point of admission as the "index date." Secondary outcomes were HCU limited to specific settings. We excluded the first 30 days following the point of admission to mitigate the confounding admission would have on the postadmission HCU trajectory. We used adjusted restricted maximum likelihood linear and nonlinear effects models to determine trajectories expressed as Canadian dollars. A total of 315 of 600 (53%) patients met eligibility criteria. Mean age was 40 years (SD = 17.4), 176 (56%) were female, 220 (70%) had focal epilepsy, and 60 (19%) had functional seizures or physiologic seizure mimics without epilepsy as adjudicated by the attending physician at the point of discharge. Mean per person health care costs increased by CAD$341.28 (95% confidence interval [CI] = -25.17 to 707.74) for each successive 6-month interval prior to SMU admission (p = .07). Following admission, mean per person costs decreased by CAD$802.34 (95% CI = 699.62-905.06, p < .001) for each successive 6-month interval up to 3 years postdischarge. Similar trends were noted for primary and specialist care, emergency department, admitted care, and when nonlinear models were applied. Admission to an SMU is associated with significant and enduring declines in HCU. Each 6-months following discharge overall HCU declined by a mean of CAD$802.34 and acute inpatient, emergency department, and outpatient physician interactions declined by 25%, 26%, and 18% respectively. Comprehensive epilepsy care not only reduces morbidity and mortality but also reduces cost.

The Effect of Mandatory Medicaid HMOs on Health Access, Utilization, and Health Outcomes for Children

ObjectiveMandatory enrollment into Medicaid-contracted Health Maintenance Organizations (HMOs) is the most common form of Medicaid managed care (MMC), but the effects of this enrollment on children are unclear. We leveraged variation in MMC implementation within and across states over time to examine the effect of mandatory Medicaid HMO enrollment on children’s access, utilization, and health outcomes. MethodsUsing Medical Expenditure Panel Survey data from 2000 to 2018 and multivariable regression models, we estimated the effects of living in a county with mandatory Medicaid HMO enrollment only, compared to other MMC types and FFS combined in one comparison group, on outcomes for children under 18 years. We also evaluated potential effect heterogeneity across age, race/ ethnicity, and for children with special healthcare needs (CSHCNs). ResultsThere were small and non-significant associations between mandatory HMO enrollment and most outcome measures. However, mandatory HMO enrollment was associated with a 1.8 percentage-point decline in the likelihood of having a usual source of care,95% CI[-0.035,-0.001], a 4.2 percentage-point increase in the likelihood of delayed access to care,95% CI[0.012,0.072], and a 2.2 percentage-point reduction in the likelihood of having any outpatient physician visits, 95% CI[-0.043,-0.0004], compared to other MMC and FFS combined in one group. Mandatory HMO enrollment was associated with more difficulty seeing a specialist for CSHCNs. ConclusionsOverall, there is little evidence that mandatory Medicaid HMO enrollment has discernable and consistent effects across a broad range of outcomes. Evaluating how mandatory Medicaid HMOs affect more nuanced healthcare measures especially for children with greater healthcare needs remains an important future research question.

Prescription of antibiotics for urinary tract infections in outpatient care in Bavaria: An analysis of routine data.

Patients with urinary tract infection (UTI) in German outpatient care are usually treated by general practitioners (GPs), as well as by other specialties. To prevent antibiotic resistances and side effects, German guidelines recommend fosfomycin, nitrofurantoin, pivmecillinam and nitroxoline as first-line treatments, and advice against broad-spectrum antibiotics such as fluoroquinolones and cephalosporins. However, data from the European Centre for Disease Prevention and Control indicates a significant proportion of second-line antibiotics in German outpatient care. Our aim was to analyze whether antibiotic prescription has changed over time in accordance with guidelines. In addition, we aimed to investigate whether specialties prescribe different antibiotics for UTIs and whether prescription varies according to patient age and sex. For patients receiving more than one antibiotic, we wanted to determine whether subsequent prescriptions show a change in substances and specialties involved. This retrospective study involved routine data (2013 to 2019) provided by the Bavarian Association of Statutory Health Insurance Physicians. Data on diagnoses and prescriptions were transmitted from outpatient care physicians on a quarterly basis. UTI patients ≥12 years were included. We analyzed 1.7 million UTI prescription cases. In females, shares of fluoroquinolones decreased sharply over time, while shares of first-line substances fosfomycin and pivmecillinam increased. Gynecologists showed the highest shares of first-line substances compared to GPs and urologists. Fluoroquinolone shares decreased in all three specialty groups. In females, older patients showed lower shares of first-line substances than younger patients. If a second or third antibiotic was prescribed, fosfomycin shares decreased, while shares of nitrofurantoin, nitroxoline and cephalosporins increased. Our findings show a trend towards a more guideline-adherent prescribing in the treatment of UTI, with a significant increase of shares of fosfomycin and pivmecillinam, especially in women, and a sharp decrease of shares of fluoroquinolones.

Evaluation of an Automated Decision Aid for the Further Referral of Emergency Room Patients—A Prospective Cohort Study.

Instruments for the initial evaluation of emergency room patients as an aid to their onward referral to ambulatory care structures are a matter of current interest. In this study, we assess the safety of the software application SmED-Kontakt+ for this purpose. SmED is an abbreviation for Strukuturierte Medizinische Ersteinschätzung Deutschland, "structured initial medical evaluation in Germany." In this prospective cohort study, we compared the recommendations of SmED-Kontakt+ concerning the time and place of further care with those of the treating physicians. The subjects were adult patients who were able to walk and had presented themselves to the emergency room. Whenever SmED-Kontakt+ assessed the situation less critically than the physicians, and in 5% of the remaining cases, the potential endangerment of patient safety was assessed by an expert panel (expected value <1%). In a total of 1840 cases, SmED-Kontakt+ agreed with the physicians' assessment in 353 (19%). The assessment of SmED-Kontakt+ was more critical in 1221 cases (66%) and less critical in 266 (15%; potential undertriage). There was potential endangerment in 49 cases (2.7%; 95% confidence interval [2.0; 3.5]). Potential endangerment was less common among patients in the more urgent recommendation categories [0.1; 2.6] and more common in the categories of a recommended outpatient physician visit or telephone consultation within or beyond 24 hours [2.4; 17.2]. SmED-Kontakt+ generally assessed these patients' needs for further care as more urgent than the treating physicians did. Nevertheless, the percentage of potentially endangered patients was higher than expected. We conclude that further care should be provided in timely fashion with an obligatory appointment. The sites of further ambulatory care should be immediately accessible and properly equipped. Patients should not be referred for further care at later times on the basis of an SmED-Kontakt+ assessment.

Prevalence of a dual diagnosis of mental illness and substance use disorder in Ontario, Canada: a retrospective cohort study using linked administrative data

ObjectivePopulation-based prevalence estimates of co-occurring mental illness and substance use disorder (herein dual diagnosis) are scarce and derived from a single source (e.g., survey data) which may lead to underestimation of prevalence. We linked administrative data to a representative mental health survey in Ontario, Canada to estimate dual diagnosis prevalence using a data triangulation method. Approach We retrospectively linked the 2002 and 2012 Canadian Community Health Survey on Mental Health (CCHS-MH) to emergency department, inpatient hospital, and outpatient physician records in Ontario, Canada. Mental illness and substance use disorder were ascertained though self-report, Composite International Diagnostic Interview screening, and linked administrative health records. We estimated 1-year, 5-year, and lifetime prevalence of dual diagnosis. ResultsOf the CCHS-MH survey participants, 14,790 (99.8%) were included in the study. The 1-year, 5-year, and lifetime prevalence of dual diagnosis was 2.3%, 4.8%, and 9.8%, respectively, which attenuated to 2.1%, 4.1%, and 8.4%, respectively, when tobacco use disorder was removed from substance use disorder ascertainment. ConclusionDual diagnosis is more common in the general population than previously estimated. Considering barriers to accessing care for both mental illness and substance use disorders among people with dual diagnosis annually, our 5-year prevalence estimate is likely most informative for health system planning. ImplicationsIn the context of increased health burden, barriers to care access, and challenges to effective treatment associated with dual diagnosis, our findings present a case for increased investment in integrated models of mental healthcare and addiction medicine.

Abstract P117: Provider Concordance to the Current 2017 High Blood Pressure (BP) Clinical Practice Guidelines and Patient Blood Pressure Control

Introduction: The AHA/ACC 2017 High BP guidelines introduced key changes, compared to previous guidelines, including a new hypertension definition (≥130/80 mm Hg) and lower medication thresholds for patients at cardiovascular risk. The impact of provider adherence to these guidelines on patient BP control has not been fully explored. Methods: We identified 3,749 new stage 1 hypertension patients (7,214 visits) and 11,013 new stage 2 hypertension patients (33,321 visits), aged ≥18, from the Vanderbilt University Medical Center database. We scrutinized outpatient BP levels, prescribed medications, follow-up visits, lab results, demographics, comorbid conditions, and physician notes from January 2018 to December 2022. This data was compared to hypertension treatment criteria developed from the 2017 guidelines that was validated by six hypertension experts. Active primary care patients (with 1 visit per year) were included. Mixed-effects Poisson regression and mixed-effects linear regression examined the relationship between guideline adherence and controlled BP (&lt;130/80 mm Hg) and continuous BP, respectively. Results: Among stage 1 hypertension visits, 12.2% were treated with at least one antihypertensive drug according to guidelines, resulting in a 13% increase in BP control and a reduction in systolic BP by 2.02 mm Hg. For stage 2 hypertension visits, 26% received treatment with at least two first-line antihypertensive drug classes, leading to a 45% increase in BP control and reductions in systolic and diastolic BP by 3.79 mm Hg and 1.93 mm Hg, respectively. No significant difference in BP control was observed among stage 2 patients treated with two versus one first-line drug. Adherence to follow-up guidelines resulted in a 24% improvement in BP control for stage 1 patients and stage 2 patients when their follow-up visit occurred within 1 month. Subsequent follow-up visits within 1-month improved BP control by 34% if BP was not controlled previously. Additionally, 42.4% of patients with uncontrolled BP for 1 month received an increase in medication dose or a change/addition of medication class and showed a 7% increase in BP control within next month. Conclusion: Provider adherence to recommended antihypertensive drug treatment guidelines (12%-26%), follow-up assessments guidelines (29%-37%), and treatment intensification (42.4%) were poor. However, patients treated according to the guidelines showed significant improved BP control.

Virtual Triage Early Detection of Inappropriate Care Seeking Intent Among Patients With Life-Threatening Cardiac Symptoms

Reports indicate that only 19% of patients with prodromal symptoms of sudden cardiac arrest seek the appropriate level of care acuity, which may be due partly to individuals being unable to distinguish which acute symptoms require urgent care. This study evaluated the degree to which patient-users of artificial intelligence-based virtual triage presenting with prodromal symptoms of a possibly life-threatening cardiac condition intended to seek the needed emergency care. A dataset of 746,282 virtual triage patient-users was examined to assess the characteristics of those reporting symptoms of potentially life-threatening cardiac conditions with no intention to seek emergency care. Of 3,968 patient-users over age 35 with severe cardiac symptoms, 89.4% did not plan to seek emergency care. A majority of patient-users did not appear to understand the level of care acuity to seek, or planned to engage self-care or to visit an outpatient physician, instead of seeking emergency care. These findings reinforce the need for much improved patient education among patients at risk for potentially life-threatening cardiac symptoms which require urgent medical care. Virtual triage (or symptom checkers) with care referral may have value in patient engagement and education to achieve this objective.

Mental health service use among mothers and other birthing parents during the COVID-19 pandemic in Ontario, Canada

BackgroundParents have reported increased symptoms of depression and anxiety during the COVID-19 pandemic. This study evaluated changes in mental health and addiction (MHA)-related health service use among mothers and other birthing parents during the COVID-19 pandemic. MethodsWe conducted a repeated cross-sectional study using health administrative data in Ontario, Canada. The population included all mothers and birthing parents (≥1 child aged 1–18, no children <1 to exclude postpartum parents) between January 2016 and December 2021. We compared rates of MHA-related outpatient physician visits, hospitalizations, and emergency department (ED) visits during COVID-19 (March 2020–December 2021) to pre-COVID-19 (pre-March 2020). ResultsMHA-related outpatient visit rates increased by 17 % (rate ratio (RR) 1.17, 95 % CI 1.16–1.18) during COVID-19. Monthly utilization rates remained higher than expected across the COVID-19 period. MHA-related ED visit rates remained lower than expected during COVID-19, while MHA-related hospitalization rates returned to expected levels by August 2020. The largest relative increases in MHA-related outpatient visits during COVID-19 were in mothers and other birthing parents living in higher income (RR 1.20, 95 % CI 1.19–1.22) or urban areas (RR 1.20, 95 % CI 1.18–1.21), with children aged 1–3 years (RR 1.23, 95 % CI 1.20–1.25) and with no history of MHA-related health service use (RR 1.20, 95 % CI 1.19–1.21). LimitationsThis study only captured physician-delivered MHA-related health service use. ConclusionsThe COVID-19 pandemic was associated with an increase in MHA-related outpatient visits among mothers and other birthing parents. These findings point to the need for improvements in mental health service access.

Возможности консервативной тактики ведения пациентов с гипертрофией и воспалением глоточной миндалины

Patients who suffer from pharyngeal tonsil hypertrophy or inflammation are very common visitors in outpatient physicians’ practice. Hypertrophy of the pharyngeal tonsil may be accompanied by persistent difficulty in nasal breathing and complications whilst adenoditis in the absence of a significant impact on the child’s quality of life and associated complications had not been regarded as a ‘pathology’ in pediatric physicians’ practice until the patient is reached the age of 7 to 9 years old. The purpose of this research was to compare the regimens of the use of the homeopathic medications in patients with pharyngeal tonsil hypertrophy or inflammation. Materials and methods used: a single-center controlled randomized observation of the use of homeopathic medications of a single active substance had been conducted in pediatric patients aged 1 to 18 y/o with pharyngeal tonsil hypertrophy or inflammation. The study included patients with pharyngeal tonsil hypertrophy or inflammation who had previously taken homeopathic single-substance medications, including in combination with standard treatment. Depending on the choice of patients (repetition of the homeopathic single-substance medications intake or prophylactic regimen) the patients were then divided into comparison groups. All of the patients had undergone both the routine examination and the ENT endoscopy, the parents’/caregivers’ satisfaction with the treatment results was then assessed using the 5-point Likert scale as well as the incidence of acute respiratory infections (ARI) in children while taking homeopathic medicines (compared to the period without taking them) and the willingness to use homeopathic medicines in the future. Results: after the ENT endoscopy (reduction in the size of the pharyngeal tonsil in 38% of cases, p≤0.001) and the parents’/caregivers’ survey (reduction in the ARI frequency in 62% of cases and high satisfaction with the treatment results), the majority of parents/caregivers have assessed the repetition of the repetition of the homeopathic single-substance medications intake as rather more effective in treatment of patients with inflammation of the pharyngeal tonsil of varying degrees of hypertrophy. Conclusion: the use of homeopathic medicines in patients with pharyngeal tonsil hypertrophy or inflammation has showed good effectiveness. According to the ENT endoscopy results before v. after the treatment and the parents’/caregivers’ survey it is preferable to repeat the homeopathic single-substance medications intake in the next adenoiditis episode. The parents’/caregivers’ readiness to go on with the homeopathic medicines’ intake ranges from 50% to 78%.

Secondary Stroke Prevention in People With Schizophrenia.

People with schizophrenia are less likely than those without to be treated for cardiovascular disease. We aimed to evaluate the association between schizophrenia and secondary preventive care after ischemic stroke. In this retrospective cohort study, we used linked population-based administrative data to identify adults who survived 1 year after ischemic stroke hospitalization in Ontario, Canada between 2004 and 2017. Outcomes were screening, treatment, and control of risk factors, and receipt of outpatient physician services. We used modified Poisson regression to model the relative risk of each outcome among people with and without schizophrenia, adjusting for age and other factors. Among 81 163 people with ischemic stroke, 844 (1.04%) had schizophrenia. Schizophrenia was associated with lower rates of screening for hyperlipidemia (60.5% versus 66.0%, adjusted relative risk [aRR] 0.88 [95% CI, 0.84-0.93]) and diabetes (69.4% versus 73.9%, aRR 0.93 [95% CI, 0.89-0.97]), prescription of antihypertensive medications (91.2% versus 94.7%, aRR 0.96 [95% CI, 0.93-0.99]), achievement of target lipid levels (low-density lipoprotein <2 mmol/L) (30.6% versus 34.6%, aRR 0.86 [95% CI, 0.78-0.96]), and outpatient specialist visits (55.3% versus 67.8%, aRR 0.78 [95% CI, 0.74-0.83]) or primary care physician visits (94.5% versus 98.5%; aRR 0.96 [95% CI, 0.95-0.98]) within 1 year. There were no differences in prescription of antilipemic, antiglycemic, or anticoagulant medications, or in achievement of target hemoglobin A1c ≤7%. People with stroke and schizophrenia are less likely than those without to receive secondary preventive care. This may inform interventions to improve poststroke care and outcomes in those with schizophrenia.

Potential and limitations of secondary prevention of noncommunicable diseases: data from a survey of Russian outpatient physicians

Aim. To identify potential and limitations of secondary prevention of noncommunicable diseases in outpatient clinics of various Russian cities.Material and methods. Outpatient physicians from 16 Russian cities took part in the cross-sectional study. A total of 545 general practitioners took part in the survey. The survey was carried out using a previously prepared questionnaire at the National Medical Research Center for Therapy and Preventive Medicine. It consisted of 11 blocks of questions, including sex and age characteristics, the prevalence of various diseases, adherence to therapy, preferential provision of medications, consultation assistance by hospital-based physicians and coverage of doctors and nursing staff. Answers were offered in several gradations to each question. Depending on the population, cities were divided into 4 following subgroups: population &gt;2 million people (Moscow and St. Petersburg), population of 1-2 million people (Samara, Rostov-onDon, Krasnodar, Krasnoyarsk, Omsk), population of 0,4-1 million people (Vladivostok, Ulyanovsk, Penza, Kursk, Kirov, Tomsk) and population &lt;400 thousand people (Nalchik, Saransk, Ivanovo).Results. In all Russian cities, among men visited a clinic, 37% were people in the age range of 50-60 years. Second place was taken by men aged 60-65 years (30%). Most often, patients present with chronic coronary artery disease (39%), followed by type 2 diabetes (22,6%). Patients present with symptoms of heart failure in 17,7% of cases. Cancer account for 11,5% in the structure of visits. A similar frequency was found for chronic obstructive pulmonary diseases (9,2%). Every third patient is partially adherent to drug correction; partial non-adherence is detected 2 times less, while complete nonadherence is &lt;3%. On average, 67% of doctors from different cities declare 75% achievement of target levels of risk factors, while one in five declare 50% achievement of recommended indicators. In most cases, physicians report minor problems during hospitalization. Every fifth doctor reported no problems, while every tenth respondent noted difficulties in hospitalizing patients. In every second case, partial staffing is noted. Moreover, a comparable trend is observed among doctors and nursing staff. In megacities and small towns the situation is somewhat better compared to cities with a population of 0,4 to 2 million.Conclusion. To optimize the secondary prevention of noncommunicable diseases, a number of measures at the outpatient healthcare level should be taken. This includes educational work on adherence to drug and non-drug treatment correction, expanding coverage of preferential medication provision, improving interaction with hospitalbased doctors and coverage of doctors and nursing staff.

Physician Follow-Up of Pediatric and Young Adult Emergency Department Visits for Substance Use in Ontario, Canada

PurposeTo study the proportion and predictors of outpatient physician follow-up within 60 days of substance-related emergency department (ED) visits for Ontario youth. MethodsWe examined administrative data on substance-related ED visits before and during the COVID-19 pandemic among youths aged 10–24 years in Ontario, Canada. Substance-related visits were identified using International Classification of Diseases-10-CA codes. We described demographic characteristics, receipt of mental health services in the year before the ED visit, disposition from the ED, and follow-up services within 60 days of the ED visit. ResultsBetween April 1, 2017, and May 31, 2021, 64,236 youth had at least one ED visit for substance use. Visits for alcohol were the most common (49%), followed by cannabis (32.3%). ED visits for all substances were more prevalent during the pandemic than prepandemic, except visits for alcohol. The receipt of follow-up physician care for substance use was low (33.2% prepandemic) but increased during the pandemic (41.7%; adjusted odds ratio 1.34, 95% CI 1.28, 1.39) and varied between substances. Mental health service history in the year before the substance-related ED visit had the strongest association with receipt of follow-up physician care within 60 days (adjusted odds ratio 6.86, 95% CI 6.57, 7.17). DiscussionYouth frequently do not receive physician follow-ups within two months of the substance-related ED visit, although higher follow-up proportions were seen during the pandemic after the implementation of virtual care. Further research is required to understand why follow-up is low and to examine interventions that can increase connection to care.

Socio-Cultural and Professional Integration of Foreign-Born and Foreign-Educated Physicians in German Outpatient Care: an Interview-Based Study in Baden-Württemberg and Hessen

Introduction In recent years, it has become increasingly hard to fill outpatient physician vacancies in all parts of Germany. This development is particularly pronounced in general practice. At the same time, the number of doctors trained abroad is increasing, predominantly in the inpatient sector. In the next few years, foreign-born and -trained physicians will presumably be increasingly active also in the field of family medicine. The aim of this study was to explore experiences, support needs and possible improvements from the perspective of such physicians in the outpatient sector with a focus on primary care.Method In this qualitative study, semi-structured interviews were conducted with physicians not raised and trained in Germany and working in the outpatient setting in Germany. The evaluation was carried out by means of qualitative content analysis. Categories were derived in a deductive-inductive manner.Results Thirteen physicians (of which nine were primary care physicians) were interviewed. Next to the deductively derived main categories (departure, des-orientation, adaptation) four subcategories as overarching problems emerged in the interviews: Administrative tasks, communication and professional as well as social adaptation / integration in Germany. Proposed solutions were categorized in structuring measures (official, easily accessible guidelines for physician migration, paid qualification period), specific preparatory courses for the outpatient sector, and personal support such as mentoring and networking of outpatient physicians in training.Conclusions Some of the problem areas mentioned were similar to those known from the inpatient setting. To support sustainable recruitment in the outpatient sector, specific preparatory courses and the promotion of networking among physicians appeared to be additional measures that would benefit physicians applying for positions in the outpatient sector and also easy to implement.

Identifying Predictors of Heart Failure Readmission in Patients From a Statutory Health Insurance Database: Retrospective Machine Learning Study.

Patients with heart failure (HF) are the most commonly readmitted group of adult patients in Germany. Most patients with HF are readmitted for noncardiovascular reasons. Understanding the relevance of HF management outside the hospital setting is critical to understanding HF and factors that lead to readmission. Application of machine learning (ML) on data from statutory health insurance (SHI) allows the evaluation of large longitudinal data sets representative of the general population to support clinical decision-making. This study aims to evaluate the ability of ML methods to predict 1-year all-cause and HF-specific readmission after initial HF-related admission of patients with HF in outpatient SHI data and identify important predictors. We identified individuals with HF using outpatient data from 2012 to 2018 from the AOK Baden-Württemberg SHI in Germany. We then trained and applied regression and ML algorithms to predict the first all-cause and HF-specific readmission in the year after the first admission for HF. We fitted a random forest, an elastic net, a stepwise regression, and a logistic regression to predict readmission by using diagnosis codes, drug exposures, demographics (age, sex, nationality, and type of coverage within SHI), degree of rurality for residence, and participation in disease management programs for common chronic conditions (diabetes mellitus type 1 and 2, breast cancer, chronic obstructive pulmonary disease, and coronary heart disease). We then evaluated the predictors of HF readmission according to their importance and direction to predict readmission. Our final data set consisted of 97,529 individuals with HF, and 78,044 (80%) were readmitted within the observation period. Of the tested modeling approaches, the random forest approach best predicted 1-year all-cause and HF-specific readmission with a C-statistic of 0.68 and 0.69, respectively. Important predictors for 1-year all-cause readmission included prescription of pantoprazole, chronic obstructive pulmonary disease, atherosclerosis, sex, rurality, and participation in disease management programs for type 2 diabetes mellitus and coronary heart disease. Relevant features for HF-specific readmission included a large number of canonical HF comorbidities. While many of the predictors we identified were known to be relevant comorbidities for HF, we also uncovered several novel associations. Disease management programs have widely been shown to be effective at managing chronic disease; however, our results indicate that in the short term they may be useful for targeting patients with HF with comorbidity at increased risk of readmission. Our results also show that living in a more rural location increases the risk of readmission. Overall, factors beyond comorbid disease were relevant for risk of HF readmission. This finding may impact how outpatient physicians identify and monitor patients at risk of HF readmission.

Association Between Medicare Site-Based Payment Policy, Physician Practice Characteristics, and Vertical Integration Among Oncologists.

Medicare's differential payments for services delivered in physician offices versus hospital outpatient settings incentivize hospital-physician integration (ie, vertical integration) across many specialties, but evidence for oncologists is mixed. We examined the association of Medicare site-based payment policy and physician practice characteristics, including service volume and diversity, with vertical integration among oncologists in 2013-2019. Using the Medicare Provider Utilization and Payment Data and Medicare Data on Provider Practice and Specialty in 2013-2019, we extracted nonintegrated medical/hematologic oncologists (hereafter oncologists) in 2013 and followed them through 2019. We quantified the incentives from Medicare site-based payment policy using the hospital-office ratio-total Medicare payments if all services were delivered in the hospital outpatient department (HOPD) versus physician office. Vertical integration was defined as billing >10% of services to HOPD in a year. Multivariable linear probability regressions estimated the association between hospital-office ratio and vertical integration in 2014-2019 with and without accounting for provider characteristics. In 2013, the average hospital-office ratio was 1.63, which increased to 1.99 in 2018. A 25th-to-75th percentile increase in the hospital-office ratio was negatively associated with integration (-1.01 percentage points [ppts], 95% CI = -1.45 to -0.57, p < .001) not accounting for physician practice characteristics; this association was attenuated (-0.30 ppts, 95% CI = -0.67 to 0.07, p = .11) after adjusting for these characteristics. Higher baseline (ie, 2013) service volume (Quartile4 v Quartile1 = -3.00 ppts, 95% CI = -4.42 to -1.59, p < .001), more diverse services (Quartile4 v Quartile1 = -3.55 ppts, 95% CI = -4.97 to -2.13, p < .001), and urban location (-5.23 ppts, 95% CI = -6.89 to -3.57, p < .001) were more strongly associated with vertical integration. Compared to Medicare site-based payment policy, oncologists' practice characteristics emerged as more potent factors for integration and should be considered to ensure the intended impacts of site-based payment reform. Our finding raises questions about the effectiveness of ongoing movements toward site-neutral payment for drug administration services to deter vertical integration in oncology.

A self-reported symptom-based decision-making model helps to rule out outpatient cases at low risk for CRC before colonoscopy

ObjectivesEffective exclusion of low-risk symptomatic outpatient cases for colorectal cancer (CRC) remains diagnostic challenges. We aimed to develop a self-reported symptom-based decision-making model for application in outpatient scenarios. MethodsIn total, 8233 symptomatic cases at risk for CRC, as judged by outpatient physicians, were involved in this study at seven medical centers. A decision-making model was constructed using 60 self-reported symptom parameters collected from the questionnaire. Further internal and external validation cohorts were built to evaluate the discriminatory power of the CRC model. The discriminatory power of the CRC model was assessed by the C-index and calibration plot. After that, the clinical utility and user experience of the CRC model were evaluated. ResultsNine symptom parameters were identified as valuable predictors used for modeling. Internal and external validation cohorts verified the adequate discriminatory power of the CRC model. In the clinical application step, all 17 physicians found the model easy to grasp, 99.9 % of the patients were satisfied with the survey form. Application of this model detected all CRC cases. The total consistency ratio of outpatient cases undergoing colonoscopy was 81.4 %. None of the low-risk patients defined by the CRC model had been diagnosed with CRC. ConclusionThis multicenter study developed and validated a simple and user-friendly decision-making model covering self-reported information. The CRC model has been demonstrated to perform well in terms of rapid outpatient decision-making scenarios and clinical utility, particularly because it can better rule out low-risk outpatient cases.

A Dwindling Matter: An Analysis of Medicare Reimbursement for Endocrine Surgery Procedures from 2000-23.

To evaluate Medicare reimbursement trends for endocrine surgeries from 2000-23. As the population ages, demand for endocrine surgeries is expected to increase. Understanding reimbursement trends is essential to ensure the financial sustainability of endocrine surgery. Data were extracted from Medicare Inpatient and Outpatient Hospital datasets, National Summary, and Physician Fee Look-up Files for nine common thyroid, parathyroid and adrenal surgeries. Data were adjusted for inflation. Descriptive statistics, compound annual growth rate (CAGR), and linear regression models were built to evaluate practice and reimbursement trends. From 2000-23, there was a 63.8% increase in endocrine surgery volume. However, inflation-adjusted average procedure reimbursements decreased by 43.2% from $1709 to $972 (CAGR -2.4%), which is the largest decrease for any surgical subspecialty reported in the published literature. At the current CAGR, the average estimated reimbursement is projected to decrease to $868 by 2030 (P<0.001). Average facility reimbursements for inpatient and outpatient hospitalizations increased. However, substantial practice pattern shifts in the study period led to decreased overall facility reimbursements, with a $17.9 million decrease in total inpatient reimbursements between 2016-21 that was only partially offset by a $3.2 million increase in outpatient hospital reimbursements. Medicare procedure reimbursements for endocrine surgeries have been outpaced by inflation, with large decreases since 2000. Concurrent changes in practice patterns have also resulted in markedly fewer inpatient stays leading to lower total facility reimbursements. Our data raise concern over the financial sustainability of the endocrine surgery field as the demand for endocrine surgery procedures increases.

Impact of COVID-19 on psychoactive medication use among individuals with intellectual and developmental disabilities in Ontario, Canada: A repeated cross-sectional study

BackgroundEvidence for worsening mental health among individuals with intellectual and developmental disabilities (IDD) during COVID-19 sparked concerns for increased use of psychoactive medications. ObjectiveTo examine the impact of COVID-19 on psychoactive medication use and clinical monitoring among individuals with IDD in Ontario, Canada. MethodsWe conducted a repeated cross-sectional study among individuals with IDD and examined weekly trends for psychoactive medication dispensing and outpatient physician visits among those prescribed psychoactive medications between April 7, 2019, and March 25, 2023. We used interventional autoregressive integrated moving average models to determine the impact of the declaration of emergency for COVID-19 (March 17, 2020) on the aforementioned trends. ResultsThe declaration of emergency for COVID-19 did not significantly impact psychoactive medication use among individuals with IDD. Provision of clinical monitoring remained relatively stable, apart from a short-term decline in the weekly rate of outpatient physician visits following the declaration of emergency for COVID-19 (step estimate: 21.26 per 1000 individuals [p < 0.01]; ramp estimate: 0.88 per 1000 individuals [p = 0.01]). When stratified by mode of delivery, there was a significant shift towards virtual care (step estimate: 78.80 per 1000 individuals; p < 0.01). The weekly rate of in-person physician visits gradually increased, returning to rates observed prior to the COVID-19 pandemic in January 2023. ConclusionAlthough access to clinical care remained relatively stable, the shift towards virtual care may have negatively impacted those who encounter challenges communicating via virtual mediums. Future research is required to identify the support systems necessary for individuals with IDD during virtual health care interactions.

Resident-led improvement project to screen for primary hyperaldosteronism in patients with resistant hypertension in an outpatient clinic

Clinical practice guidelines recommend screening for primary hyperaldosteronism (PH) in patients with resistant hypertension. However, screening rates are low in the outpatient setting. We sought to increase screening rates for...
