An assessment of the association between patient characteristics and timely lung cancer treatment.

PURPOSE: Prior data have demonstrated relationships between patient characteristics, the use of surgery to treat lung cancer, and the timeliness of treatment. Our study examines whether these relationships were observable in 2019 in patients with Medicare Advantage health plans being treated for lung cancer. METHODS: Claims data pertaining to patients with Medicare Advantage health plans who had received radiation therapy (RT) or surgery to treat lung cancer within 90 days of diagnostic imaging were extracted. Other databases were used to determine patients' demographics, comorbidities, the urbanicity of their ZIP code, the median income of their ZIP code, and whether their treatment was ordered by a physician at a hospital. Multivariable logistic and Cox Proportional Hazards models were used to assess the association between patient characteristics, receipt of surgery, and time to non-systemic treatment (surgery or RT), respectively. RESULTS: A total of 2,682 patients were included in the analysis. In an adjusted analysis, patients were significantly less likely to receive surgery if their first ordering physician was based in a hospital, if they were older, if they had a history of congestive heart failure (CHF), if they had a history of chronic obstructive pulmonary disease, or if they had stage III lung cancer. Likewise, having stage III cancer was associated with significantly shorter time to treatment. CONCLUSIONS: Within a Medicare Advantage population, patient demographics were found to be significantly associated with the decision to pursue surgery, but factors other than stage were not significantly associated with time to non-systemic treatment.

An assessment of the association between patient race and prior authorization program determinations in the context of radiation therapy.

BACKGROUND: When a physician determines that a patient needs radiation therapy (RT), they submit an RT order to a prior authorization program which assesses guideline-concordance. A rule-based clinical decision support system (CDSS) evaluates whether the order is appropriate or potentially non-indicated. If potentially non-indicated, a board-certified oncologist discusses the order with the ordering physician. After discussion, the order is authorized, modified, withdrawn, or recommended for denial. Although patient race is not captured during ordering, bias prior to and during ordering, or during the discussion, may influence outcomes. This study evaluated if associations existed between race and order determinations by the CDSS and by the overall prior authorization program. METHODS: RT orders placed in 2019, pertaining to patients with Medicare Advantage health plans from one national organization, were analyzed. The association between race and prior authorization outcomes was examined for RT orders for all cancers, and then separately for breast, lung, and prostate cancers. Analyses controlled for the patient's age, urbanicity, and the median income in the patient's ZIP code. Adjusted analyses were conducted on unmatched and racially-matched samples. RESULTS: Of the 10,145 patients included in the sample, 8,061 (79.5%) were White and 2,084 (20.5%) were Black. Race was not found to have a significant association with CDSS or prior authorization outcomes in any of the analyses. CONCLUSIONS: CDSS and prior authorization outcomes suggested similar rates of clinical appropriateness of orders for patients, regardless of race. IMPLICATIONS: Prior authorization utilizing rule-based CDSS was capable of enforcing guidelines without introducing racial bias.

The association between provider characteristics and post-catheterization interventions.

OBJECTIVES: To examine whether the demographics of providers' prior year patient cohorts, providers' historic degree of catheter-based fractional flow reserve (FFR) utilization, and other provider characteristics were associated with post-catheterization performance of percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). STUDY DESIGN: A retrospective, observational analysis of outpatient claims data was performed. METHODS: All 2018 outpatient catheterization claims from a national organization offering commercial and Medicare Advantage health plans were examined. Claims were excluded if the patient had a prior catheterization in 2018, had any indications of CABG or valvular heart disease in the prior year of claims, or if the provider had ≤10 catheterization claims in 2017. Downstream PCI and CABG were determined by examining claims 0-30 days post-catheterization. Using multivariate mixed effects logistic regression with provider identity random effects, the association between post-catheterization procedures and provider characteristics was assessed, controlling for patient characteristics. RESULTS: The sample consisted of 31,920 catheterization claims pertaining to procedures performed by 964 providers. Among the catheterization claims, 8,554 (26.8%) were followed by PCI and 1,779 (5.6%) were followed by CABG. Catheterizations performed by providers with older prior year patient cohorts were associated with higher adjusted odds of PCI (1.78; CI: 1.26-2.53), even after controlling for patient age. Catheterizations performed by providers with greater historic use of FFR had significantly higher adjusted odds of being followed by PCI (1.73; CI: 1.26-2.37). CONCLUSION: Provider characteristics may impact whether patients receive a procedure post-catheterization. Further research is needed to characterize this relationship.

A Description of Outcomes Experienced by Patients Whose Orders for Peripheral Artery Revascularization Were Reviewed by a Nondenial Prior Authorization Program.

OBJECTIVE: After a nondenial prior authorization program evaluates orders for peripheral artery revascularization (PAR), ordering physicians sometimes withdraw their orders based upon program recommendations. Some patients with withdrawn orders receive PAR if claudication does not resolve. To characterize patient outcomes under this program, we evaluated whether associations existed between the withdrawal of patients' initial PAR orders and the presence of claims for PAR and claims mentioning intermittent claudication (IC) in the following 16 weeks. METHODS: Orders for PAR placed from 1/1/19 to 9/30/19 for patients with Medicare Advantage health plans were extracted from a national healthcare organization's database. Claims data from 0 to 16 weeks following the order were reviewed to determine if patients had downstream PAR claims, or if they had emergency department or hospital claims mentioning IC. Chi-square tests were used to assess the association between order withdrawal and downstream PAR, as well as claims mentioning IC. Multivariate logistic regressions were run to assess the same, controlling for patient age, sex, urbanicity, local median income, state obesity rate, type of PAR, ordering physician specialty, and whether PAR was ordered in a hospital setting. RESULTS: Of 1588 orders meeting inclusion criteria, 71.9% (1038/1444) of authorized orders and 61.1% (88/144) of withdrawn orders were followed by PAR within 16 weeks, a significant difference (P < .01). Relatedly, 69.8% (1008/1444) of authorized orders and 70.8% (102/144) of withdrawn orders were followed by IC claims, an insignificant difference. Multivariate logistic regressions showed patients with withdrawn PAR orders had significantly lower adjusted odds of PAR (OR: 0.63; 95% CI: 0.44-0.91), but an insignificant difference in their adjusted odds of IC (OR: 1.10; CI: 0.76-1.64). CONCLUSIONS: Although patients with withdrawn PAR orders were significantly less likely to receive PAR in the subsequent 16 weeks, no association was found between withdrawn PAR orders and subsequent claims mentioning IC.

Utilization Trends of a Government-Sponsored Health Insurance Program in South India: 2014 to 2018.

OBJECTIVES: To characterize the utilization trends associated with the Aarogyasri health insurance scheme in Andhra Pradesh, India. METHODS: This is a retrospective cross-sectional study including participants enrolled in the Aarogyasri health insurance scheme, with recorded claims pertaining to inpatient care from quarter 3, 2014 through quarter 2, 2018. The main outcome measure, was annual utilization by service category, trended to characterize changes in the mean claim amount and the median length of stay. Mortality by service category was also trended. Mann-Kendall correlation was used to evaluate trends. Additionally, interdistrict migration for care in 2014 versus 2018 was examined to evaluate changes in access to care. RESULTS: The distribution of claims by caste significantly shifted over time, with members of backward castes and scheduled tribes filing more claims, and members of other castes and scheduled castes filing fewer claims. The median age of patients significantly increased, rising from 44.0 years in 2014 to 46.0 years in 2018. The nominal mean claim amount in 2018 was 105.4% of the 2014 average, but the 2018 real mean claim amount was 90.3% of the 2014 average. The median length of stay significantly decreased from 5 to 4 days. Mortality rates after procedures significantly decreased from 2.4% to 2.1%. Interdistrict migration to access care remained high among beneficiaries from the districts YSR Kadapa and West Godaveri in 2014 and 2018. CONCLUSIONS: Over time, the value delivered by Aarogyasri improved. More patients received care at lower real per claim cost, with a concurrent decline in mortality.

Characterizing Cardiac Catheterization Utilization in a US Population with Commercial or Medicare Advantage Health Plans.

Background: Health plans and health systems need to understand the demand for common healthcare services to ensure adequate access to care. Utilization of cardiac catheterization is of particular interest, because it is relatively common and has the potential for variation across subpopulations, similar to the level of geographical variation in heart disease in the United States. Objectives: To illustrate how the utilization of cardiac catheterization has changed over time in a US population with commercial and Medicare Advantage health plans, and how it differs between subpopulations. Methods: Cardiac catheterization claims data from 2012 to 2018 were extracted from the database of a national healthcare organization offering commercial and Medicare Advantage health plans. Contemporaneous health plan enrollment data and government data were used to determine the patients' characteristics. Annual catheterizations per 1000 patients for the population as a whole and for subpopulations were determined using claims data. Spearman's rank-order correlation was used to assess the monotonicity of trends. Catheterization utilization for each subpopulation was compared with that of the population average. A second, patient-level analysis was used to determine the factors predictive of patients' catheterization utilization in 2018. Results: Across the overall population, the rate of cardiac catheterization was stable from 2012 to 2018. An adjusted analysis of 2018 data showed that catheterization utilization was significantly associated with older age, male sex, residence in a rural zip code, residence in a lower-income zip code, and residence in a state with a high obesity rate. The trendlines of the relative utilization of catheterization in subpopulations over time revealed similar patterns. Conclusion: Marked differences were observed in the rates of cardiac catheterization utilization between the subpopulations in our study. Overall, these data show a direct correlation between geographic residence, obesity level, wealth, and the rate of cardiac catheterization utilization. To ensure adequate access to care, health plans and health systems should explore the implications of disproportionately high demand for cardiac catheterization in populations from lower-income areas, higher obesity rate states, rural patients, and older patients.

Generating value with mental health apps.

BACKGROUND: Although apps are increasingly being used to support the diagnosis, treatment and management of mental illness, there is no single means through which costs associated with mental apps are being reimbursed. Furthermore, different apps are amenable to different means of reimbursement as not all apps generate value in the same way. AIMS: To provide insights into how apps are currently generating value and being reimbursed across the world, with a particular focus on the situation in the USA. METHOD: An international team performed secondary research on how apps are being used and on common pathways to remuneration. RESULTS: The uses of apps today and in the future are reviewed, the nature of the value delivered by apps is summarised and an overview of app reimbursement in the USA and other countries is provided. Recommendations regarding how payments might be made for apps in the future are discussed. CONCLUSIONS: Currently, apps are being reimbursed through channels with other original purposes. There may be a need to develop an app-specific channel for reimbursement which is analogous to the channels used for devices, drugs and laboratory tests.

Impact of the Artificial Nudge.

RATIONALE AND OBJECTIVES: Artificial intelligence (AI) is playing a growing role in the field of radiology. This article seeks to help readers quantify its impact when put into practice, using a lung nodule flagger as an example. MATERIALS AND METHODS: The one-time and ongoing costs associated with AI are explored. Costs are divided into three categories: direct costs, costs associated with operational changes, and downstream costs. Examples of each are provided. RESULTS: A framework for estimating the financial impact of AI is provided. CONCLUSION: The impact of AI is quantifiable, but estimates of its financial impact may not be portable across contexts. Different organizations may implement AI in different ways due to differences in clinical practices. Furthermore, different organizations have different hurdle rates for their investments. Finally, international cost-effectiveness analyses may not be generalizable due to differences in both practice patterns and the valuation placed upon quality. When quantifying the impact of AI, organizations should consider relying upon pilots and data from other similarly-situated organizations.

Health Care Utilization and Pain Outcomes Following Early Imaging for Low Back Pain in Older Adults.

BACKGROUND: Professional societies have provided inconsistent guidance regarding whether older patients should receive early imaging for low back pain, in the absence of clinical indications. The study assesses the implications of early imaging by evaluating its association with downstream utilization in an elderly population. METHODS: Patients were included if they had a Medicare Advantage plan, had claims-based evidence of low back pain in 2014, and lacked conditions justifying early imaging. The outcomes examined were short-term, nonchronic, and chronic opioid use, steroid injections, and spinal surgery in the following 730 days, and persistent low back pain at 180 to 365 days. Morphine dose equivalents of opioid use was used as a measure of intensity. Logistic and γ regressions were used to assess the association between imaging in the first 6 weeks and the outcomes. RESULTS: Among the 57,293 patients meeting inclusion criteria, the mean age was 71.2, and 26,606 (46.4%) received early imaging. Early imaging was associated with increased adjusted odds of short-term (odds ratio [OR], 1.21; 95% CI, 1.15 to 1.28), nonchronic (OR, 1.78; 95% CI, 1.69 to 1.88), and chronic (OR, 1.13; 95% CI, 1.07 to 1.18) opioid use, as well as steroid injections (OR, 2.55; 95% CI, 2.28 to 2.85) and spinal surgery (OR, 3.40; 95% CI, 2.97 to 3.90). Patients that received early imaging were more likely to experience persistent pain (OR, 1.09; 95% CI, 1.05 to 1.14) and used significantly more morphine dose equivalents if they had nonchronic opioid use. CONCLUSIONS: Early imaging for low back pain in older individuals was common, and was associated with greater utilization of downstream services and persistent pain.

Outpatient facility-based order variation in combined imaging.

OBJECTIVE: Combined computed tomography (CT) occurs when one anatomical area is simultaneously imaged both without and with contrast, or two overlapping anatomical areas are imaged concurrently. While this has been studied in a Traditional Medicare population, it has not been studied in other populations subject to prior authorization. This study explores between-facility variation in ordering and receiving orders to render combined CT in a mixed commercial and Medicare Advantage population. METHODS: Orders for CT abdomen (without/with contrast), CT thorax (without/with contrast), and concurrent CT brain and sinus authorized by a prior authorization company from 2013-2017, pertaining to patients with commercial or Medicare Advantage health plans from one national insurer, were extracted. Orders were issued and rendered by both hospitals and nonhospitals. The analysis was performed separately for each anatomical area in two ways: orders were grouped by ordering facility, and by designated rendering facility. For each facility, the ratio of combined to total orders was calculated, and analysis of variance was used to determine whether there were significant differences in this rate by year. The association between health plan type and combined imaging rates was assessed. RESULTS: Combined rates [ratio±standard deviation] for abdomen, thorax, and brain/sinus were 0.306±0.246, 0.089±0.142, and 0.002±0.01 respectively when the analysis was conducted according to ordering facility, and 0.311±0.178, 0.096±0.113, and 0.001±0.006 when the analysis was conducted according to designated rendering facility. Combined CT abdomen and CT thorax rates decreased monotonically from 2013 to 2017, decreases that were significant (P < .01) regardless of whether orders were grouped by ordering or rendering facility. Combined CT abdomen and CT thorax rates significantly differed between orders pertaining to people with commercial and Medicare Advantage plans. DISCUSSION: Variability was greater when orders were grouped by ordering facility, rather than rendering facility. Health plan type may influence whether a patient receives combined CT.

Determinants of outcomes following outpatient placement of implantable cardioverter defibrillators in a Medicare Advantage population.

BACKGROUND: Recipients of ICD are likely to have several risk factors that could interfere with successful use of implantable cardioverter defibrillators (ICDs). HYPOTHESIS: Age, sex, and factors indicated in claims are associated with one-year mortality and complications after ICD placement. METHODS: Adult Medicare Advantage patients who underwent outpatient ICD implantation from January 2014 to September 2015 were included. Age, sex, Charlson Comorbidity Index (CCI), prior year hospitalization and emergency department (ED) visit, diabetes, heart failure, ischemic heart disease, and indicators of the need for pacing were evaluated as risk factors. Mortality and device-related complications (lead and nonlead) were assessed at one-year post-procedure using Kaplan-Meier and Cox Proportional Hazard analysis. RESULTS: Among 8450 patients who underwent implantation, 1-year event-free survival was 80.1%, based on an overall composite measure of complications and mortality. Adjusted survival analysis showed that age ≥ 65, male sex, incremental increase in CCI, heart failure, prior year hospitalization, ED visit, and prior year pacing procedure were significant predictors of mortality. Age ≥ 65, male sex, and prior year hospitalization were significant predictors of a composite measure of device-related complications. CCI and prior hospitalization were significant predictors of a composite measure of any adverse outcome. CONCLUSIONS: Results suggest most patients in an older population do not experience adverse outcomes in the year following ICD implantation. The risk of mortality may be greater in men, patients over the age of 65, and patients with greater general morbidity, heart failure, or a history of a pacing procedure.

Presentation at computed tomography (CT) scan of the thorax and first year diagnostic and treatment utilization among patients diagnosed with lung cancer.

BACKGROUND: As Medicare expands the use of computed tomography (CT) for diagnosing lung cancer, there is increased opportunity to diagnose lung cancer in asymptomatic patients. This descriptive study characterizes the disease-specific diagnostic and treatment services that patients with a positive diagnosis following CT received, stratified by presentation at CT. METHODS: Patients who were diagnosed with lung cancer following CT in 2013, had no history of lung cancer, survived at least 1 year, were aged 55-80 years, and had Medicare Advantage insurance were included. Patients were grouped based upon presentation at CT: morbidities unrelated to lung cancer, classic lung cancer symptoms, and cancer syndromes. Patients with none of these factors were categorized into a no diagnoses/symptoms group. The type and intensity of services used in the year following the CT was reported for each group. RESULTS: 1,261 patients were included. Early treatment services were most common in the group with morbidities unrelated to lung cancer (13.7%) and least common in the cancer syndromes group (6.6%). Advanced treatment services were used by 47.3% of the cancer syndromes group versus 23.5% of the no diagnoses/symptoms group. CONCLUSIONS: The intensity of disease-specific diagnostic and treatment services varied by presentation at CT. Patients with no symptoms or morbidities at the time of CT less frequently received advanced interventions. Learning about the utilization patterns of others with a similar presentation at CT may help patients with positive lung cancer diagnoses engage in shared decision making and in norming their experiences against those of other similarly-situated patients.

The Economic Benefits of Mobile Apps for Mental Health and Telepsychiatry Services When Used by Adolescents.

This article describes the benefits resulting from the use of mobile applications for mental health and telepsychiatry. Potential direct benefits include substitution for other forms of care, prevention of higher-acuity illness, higher rate of psychiatrist use, increased competition of services driving lower treatment costs, lower operating costs for psychiatrists, fewer missed appointments, and revenue for application developers. Potential indirect benefits include improved physical health, enhanced current and future productivity, and reduced demands on caregivers. A return on investment analysis framework is then presented as a generalized means for evaluating the return on investment of specific health care interventions.

Do Case Rates Affect Physicians' Clinical Practice in Radiation Oncology?: An Observational Study.

Case rate payments combined with utilization monitoring may have the potential to improve the quality of care by reducing over and under-treatment. Thus, a national managed care organization introduced case rate payments at one multi-site radiation oncology provider while maintaining only fee-for-service payments at others. This study examined whether the introduction of the payment method had an effect on radiation fractions administered when compared to clinical guidelines. The number of fractions of radiation therapy delivered to patients with bone metastases, breast, lung, prostate, and skin cancer was assessed for concordance with clinical guidelines. The proportion of guideline-based care ascertained from the payer's claims database was compared before (2011) and after (2013) the payment method introduction using relative risks (RR). After the introduction of case rates, there were no significant changes in guideline-based care in breast, lung, and skin cancer; however, patients with bone metastases and prostate cancer were significantly more likely to have received guideline-based care (RR = 2.0 and 1.1, respectively, p<0.05). For the aggregate of all cancers, the under-treatment rate significantly declined (p = 0.008) from 4% to 0% after the introduction of case rate payments, while the over-treatment rate remained steady at 9%, with no significant change (p = 0.20). These findings suggest that the introduction of case rate payments did not adversely affect the rate of guideline-based care at the provider examined. Additional research is needed to isolate the effect of the payment model and assess implications in other populations.

The increased financial burden of further proposed orthopaedic resident work-hour reductions.

BACKGROUND: Increased funding for graduate medical education was not provided during implementation of the eighty-hour work week. Many teaching hospitals responded to decreased work hours by hiring physician extenders to maintain continuity of care. Recent proposals have included a further decrease in work hours to a total of fifty-six hours. The goal of this study was to determine the direct cost related to a further reduction in orthopaedic-resident work hours. METHODS: A survey was delivered to 152 residency programs to determine the number of full-time equivalent (FTE) physician extenders hired after implementation of the eighty-hour work-week restriction. Thirty-six programs responded (twenty-nine university-based programs and seven community-based programs), encompassing 1021 residents. Previous published data were used to determine the change in resident work hours with implementation of the eighty-hour regulation. A ratio between change in full-time equivalent staff per resident and number of reduced hours was used to determine the cost of the proposed further decrease. RESULTS: After implementation of the eighty-hour work week, the average reduction among orthopaedic residents was approximately five work hours per week. One hundred and forty-three physician extenders (equal to 142 full-time equivalent units) were hired to meet compliance at a frequency-weighted average cost of $96,000 per full-time equivalent unit. A further reduction to fifty-six hours would increase the cost by $64,000 per resident. With approximately 3200 orthopaedic residents nationwide, sensitivity analyses (based on models of eighty and seventy-three-hour work weeks) demonstrate that the increased cost would be between $147 million and $208 million per fiscal year. For each hourly decrease in weekly work hours, the cost is $8 million to $12 million over the course of a fiscal year. CONCLUSIONS: Mandated reductions in resident work hours are a costly proposition, without a clear decrease in adverse events. The federal government should consider these data prior to initiating unfunded work-hour mandates, as further reductions in resident work hours may make resident education financially unsustainable.
