Abstract
BACKGROUND Insured patients who receive out-of-network care may receive a "balance bill" for the difference between the practitioner's charge and their insurer's contracted rate. In 2017, California banned balance billing for anesthesia care. This study examined the association between California's law and subsequent payments for anesthesia care. The authors hypothesized that, after the law's implementation, there would be no change in in-network payment amounts, and that out-of-network payment amounts and the portion of claims occurring out-of-network would decline. METHODS The study used average, quarterly, California county-level payment data (2013 to 2020) derived from a claims database of commercially insured patients. Using a difference-in-differences approach, the change was estimated in payment amounts for intraoperative or intrapartum anesthesia care, along with the portion of claims occurring out-of-network, after the law's implementation. The comparison group was office visit payments, expected to be unaffected by the law. The authors prespecified that they would refer to differences of 10% or greater as policy significant. RESULTS The sample consisted of 43,728 procedure code-county-quarter-network combinations aggregated from 4,599,936 claims. The law's implementation was associated with a significant 13.6% decline in payments for out-of-network anesthesia care (95% CI, -16.5 to -10.6%; P < 0.001), translating to an average $108 decrease across all procedures (95% CI, -$149 to -$64). There was a statistically significant 3.0% increase in payments for in-network anesthesia care (95% CI, 0.9 to 5.1%; P = 0.007), translating to an average $87 increase (95% CI, $64 to $110), which may be notable in some circumstances but did not meet the study threshold for identifying a change as policy significant. There was a nonstatistically significant increase in the portion of claims occurring out-of-network (10.0%, 95% CI, -4.1 to 24.2%; P = 0.155). CONCLUSIONS California's balance billing law was associated with significant declines in out-of-network anesthesia payments in the first 3 yr after implementation. There were mixed statistical and policy significant results for in-network payments and the proportion of out-of-network claims. EDITOR’S PERSPECTIVE

Freestanding Ambulatory Surgery Centers and Patients Undergoing Outpatient Knee Arthroplasty. JAMA Netw Open 2023; 6:e2328343. [PMID: 37561458 PMCID: PMC10415959 DOI: 10.1001/jamanetworkopen.2023.28343] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/10/2022] [Accepted: 06/30/2023] [Indexed: 08/11/2023] Open
Abstract
Importance In 2018, Medicare removed total knee arthroplasty from the list of inpatient-only procedures, resulting in a new pool of patients eligible for outpatient total knee arthroplasty. How this change was associated with the characteristics of patients undergoing outpatient knee arthroplasty at hospital-owned surgery centers (HOSCs) vs freestanding ambulatory surgery centers (FASCs) is unknown. Objectives To describe the characteristics of patients undergoing outpatient, elective total and partial knee arthroplasty in 2017 and 2018 and to compare the cohorts receiving treatment at FASCs and HOSCs. Design, Setting, and Participants This observational retrospective cohort study included 5657 patients having elective, outpatient partial and total knee arthroplasty in the Florida and Wisconsin State Ambulatory Surgery Databases in 2017 and 2018. Prior admissions were identified in the State Inpatient Database. Statistical analysis was performed from March to June 2022. Main Outcomes and Measures Characteristics of patients undergoing surgery at a FASC vs a HOSC in 2017 and 2018 were compared. Results A total of 5657 patients (mean [SD] age, 64.2 [9.9] years; 2907 women [51.4%]) were included in the study. Outpatient knee arthroplasties increased from 1910 in 2017 to 3747 in 2018 and were associated with an increase in total knee arthroplasties (474 in 2017 vs 2065 in 2018). The influx of patients undergoing outpatient knee arthroplasty was associated with an amplification of differences between the patients treated at FASCs and the patients treated at HOSCs. Patients with private payer insurance seen at FASCs increased from 63.4% in 2017 (550 of 867) to 72.7% in 2018 (1272 of 1749) (P < .001), while the percentage of patients with private payer insurance seen at HOSCs increased, but to a lesser extent (41.6% [427 of 1027] in 2017 vs 46.4% [625 of 1346] in 2018; P < .001). In 2017, the percentages of White patients seen at FASCs and HOSCs were similar (85.0% [737 of 867] vs 88.2% [906 of 1027], respectively); in 2018, the percentage of White patients seen at FASCs had increased and was significantly different from the percentage of White patients seen at HOSCs (90.6% [1585 of 1749] vs 87.9% [1183 of 1346]; P = .01). Both types of facilities saw an increase from 2017 to 2018 in the percentage of patients from communities of low social vulnerability, but this increase was greater for FASCs (FASCs: 6.7% [58 of 867] in 2017 vs 33.9% [593 of 1749] in 2018; HOSCs: 7.6% [78 of 1027] in 2017 vs 21.2% [285 of 1346] in 2018). Finally, while FASCs and HOSCs had cared for a similar portion of patients with prior admissions in 2017 (7.8% [68 of 867] vs 9.4% [97 of 1027], respectively; P = .25), in 2018, FASCs cared for fewer patients with prior admissions than HOSCs (4.0% [70 of 1749] vs 8.1% [109 of 1346]; P < .001). Conclusions This study suggests that the increase in the number of patients undergoing outpatient knee arthroplasty in 2018 corresponded to FASCs treating a greater share of patients who were White, covered by private payer insurance, and healthier. These findings raise a concern that as more operations transition to the outpatient setting, variability in access to FASCs may increase, leaving hospital-owned centers to bear a greater share of the burden of caring for more vulnerable patients with more severe illness.

The Price-Quality Mismatch: Are Negotiated Prices for Total Joint Arthroplasty Associated With Hospital Quality in a Large California Health System? Clin Orthop Relat Res 2023; 481:1061-1068. [PMID: 36729581 PMCID: PMC10194750 DOI: 10.1097/corr.0000000000002489] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Accepted: 10/20/2022] [Indexed: 02/03/2023]
Abstract
BACKGROUND Price variations in healthcare can be caused by quality or factors other than quality such as market share, negotiating power with insurers, or hospital ownership model. Efforts to improve care value (defined as the ratio between health outcomes and price) by making healthcare prices readily accessible to patients are driven by the assumption this can help patients more easily identify high-quality, low-price clinicians and health systems, thus reducing price variations. However, if price variations are driven by factors other than quality, then strategies that involve payments for higher-quality care are unlikely to reduce price variation and improve value. It is unknown whether prices for total joint arthroplasty (TJA) are correlated with the quality of care or whether factors other than quality are responsible for price variation. QUESTIONS/PURPOSES (1) How do prices insurers negotiate for TJA paid to a single, large health system vary across payer types? (2) Are the mean prices insurers negotiate for TJA associated with hospital quality? METHODS We analyzed publicly available data from 22 hospitals in a single, large regional health system, four of which were excluded owing to incomplete quality information. We chose to use data from this single health system to minimize the confounding effects of between-hospital reputation or branding and geographic differences in the cost of providing care. This health system consists of large and small hospitals serving urban and rural populations, providing care for more than 3 million individuals. For each hospital, negotiated prices for TJA were classified into five payer types: commercial in-network, commercial out-of-network, Medicare Advantage (plans to which private insurers contract to provide Medicare benefits), Medicaid, and discounted cash pay. Traditional Medicare plans were not included because the prices are set statutorily, not negotiated. We obtained hospital quality measures from the Centers for Medicare and Medicaid Services. Centers for Medicare and Medicaid Services quality measures included TJA-specific complication and readmission rates in addition to hospital-wide patient survey star rating (measure of patient care experience) and total performance scores (aggregate measure of clinical outcomes, safety, patient experience, process of care, and efficiency). We evaluated the association between the mean negotiated hospital prices and Centers for Medicare and Medicaid Services quality measures using Pearson correlation coefficients and Spearman rho across all payer types. Statistical significance was defined as p < 0.0025. RESULTS The mean ± SD overall negotiated price for TJA was USD 54,500 ± 23,200. In the descriptive analysis, the lowest negotiated prices were associated with Medicare Advantage (USD 20,400 ± 1800) and Medicaid (USD 20,300 ± 8600) insurance plans, and the highest prices were associated with out-of-network care covered by commercial insurance plans (USD 78,800 ± 9200). There was no correlation between the mean negotiated price and TJA complication rate (discounted cash price: r = 0.27, p = 0.29; commercial out-of-network: r = 0.28, p = 0.26; commercial in-network: r = -0.07, p = 0.79; Medicare Advantage: r = 0.11, p = 0.65; Medicaid: r = 0.03, p = 0.92), readmission rate (discounted cash price: r = 0.19, p = 0.46; commercial out-of-network: r = 0.24, p = 0.33; commercial in-network: r = -0.13, p = 0.61; Medicare Advantage: r = -0.06, p = 0.81; Medicaid: r = 0.09, p = 0.74), patient survey star rating (discounted cash price: r = -0.55, p = 0.02; commercial out-of-network: r = -0.53, p = 0.02; commercial in-network: r = -0.37, p = 0.13; Medicare Advantage: r = -0.08, p = 0.75; Medicaid: r = -0.02, p = 0.95), or total hospital performance score (discounted cash price: r = -0.35, p = 0.15; commercial out-of-network: r = -0.55, p = 0.02; commercial in-network: r = -0.53, p = 0.02; Medicare Advantage: r = -0.28, p = 0.25; Medicaid: r = 0.11, p = 0.69) for any of the payer types evaluated. CONCLUSION There is substantial price variation for TJA that is not accounted for by the quality of care, suggesting that a mismatch between price and quality exists. Efforts to improve care value in TJA are needed to directly link prices with the quality of care delivered, such as through matched quality and price reporting mechanisms. Future studies might investigate whether making price and quality data accessible to patients, such as through value dashboards that report easy-to-interpret quality data alongside price information, moves patients toward higher-value care decisions. CLINICAL RELEVANCE Efforts to better match the quality of care with negotiated prices such as matched quality and price reporting mechanisms, which have been shown to increase the likelihood of choosing higher-value care in TJA, could improve the value of care.

Abstract
The coronavirus disease 2019 public health emergency (PHE) caused extensive job loss and loss of employer-sponsored insurance. State Medicaid programs experienced a related increase in enrollment during the PHE. However, the composition of enrollment and enrollee changes during the pandemic is unknown. This study examined changes in Medicaid enrollment and population characteristics during the PHE. A retrospective study documenting changes in Medicaid new enrollment and disenrollment, and enrollee characteristics between March and October 2020 compared to the same time in 2019 using full-state Medicaid populations from 6 states of a wide geographical region. The primary outcomes were Medicaid enrollment and disenrollment during the PHE. New enrollment included persons enrolled in Medicaid between March and October 2020 who were not enrolled in January or February, 2020. Disenrollment included persons who were enrolled in March of 2020 but not enrolled in October 2020. The study included 8.50 million Medicaid enrollees in 2020 and 8.46 million in 2019. Overall, enrollment increased by 13.0% (1.19 million) in the selected states during the PHE compared to 2019. New enrollment accounted for 24.9% of the relative increase, while the remaining 75.1% was due to disenrollment. A larger proportion of new enrollment in 2020 was among adults aged 27 to 44 (28.3% vs 23.6%), Hispanics (34.3% vs 32.5%) and in the financial needy (44.0% vs 39.0%) category compared to 2019. Disenrollment included a larger proportion of older adults (26.1% vs 8.1%) and non-Hispanics (70.3% vs 66.4%) than in 2019. Medicaid enrollment grew considerably during the PHE, and most enrollment growth was attributed to decreases in disenrollment rather than increases in new enrollment. Our results highlight the impact of coronavirus disease 2019 on state health programs and can guide federal and state budgetary planning once the PHE ends.

Adoption of hospital diagnosis-related group financing in Switzerland and the availability of computed tomography scanners. HEALTH ECONOMICS 2022; 31:2537-2557. [PMID: 36046948 DOI: 10.1002/hec.4594] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/19/2021] [Revised: 07/13/2022] [Accepted: 08/17/2022] [Indexed: 06/15/2023]
Abstract
We study the relationship between diagnosis-related group (DRG) financing and the availability of computed tomography (CT) scanners in Switzerland. A number of Swiss hospitals switched to DRG payment for a portion of their payments progressively between 2002 and 2011. As of 2012, all hospitals were required to use DRG payment for a substantial portion of reimbursement. We conducted two main analyses. First, we studied hospitals switching in 2002-2011 and estimated event study models to compare changes in CT availability before and after the adoption of DRG financing, using the hospitals that did not switch during this time as a comparison group. In the second, we compared trends in CT availability before and after 2012, for the hospitals that switched in that year. In both analyses, we find a statistically significant association between the switch to DRG financing and lower levels of CT availability.

Prevalence, Burden, and Sources of Out-of-Network Billing in Elective Hand Surgery: A National Claims Database Analysis. J Hand Surg Am 2022; 47:934-943. [PMID: 35927122 DOI: 10.1016/j.jhsa.2022.06.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/03/2021] [Revised: 04/09/2022] [Accepted: 06/01/2022] [Indexed: 02/02/2023]
Abstract
PURPOSE Surprise out-of-network (OON) bills can represent a considerable cost burden on patients. However, OON billing remains underexplored in elective, outpatient surgery procedures, which have greater latitude for patient choice. We aimed to answer the following questions: (1) What is the prevalence and magnitude of OON charges in hand surgery? (2) What are the sources of OON charges? and (3) What factors are associated with OON charges? METHODS We analyzed patient-level data from the Clinformatics Data Mart database. We identified patients undergoing carpal tunnel release, trigger finger release, wrist ganglion removal, de Quervain release, limited palmar fasciectomy, or thumb carpometacarpal arthroplasty at in-network facilities with an in-network primary surgeon. The primary outcome was the proportion of surgical episodes with at least 1 OON charge. Secondary outcomes included the magnitude of potential balance bills (portion of OON bill exclusive of the standardized payment and expected patient cost-sharing), sources of OON charges, and factors associated with OON charges. RESULTS Of 112,211 elective hand surgery episodes, 8% (9,158) had at least 1 OON charge. OON charges ranged from $1,154 (95% confidence interval, $1,018-$1,289) for wrist ganglion removal to $3,162 (95% confidence interval, $2,902-$3,423) for thumb carpometacarpal arthroplasty. In episodes with OON charges, the major sources of OON charges were anesthesiologists (75% of episodes), durable medical equipment (10% of episodes), and pathologists (9% of episodes). Site of service, geographic region, and health exchange-purchased plans were highly associated with OON charges. CONCLUSIONS Out-of-network billing can represent a substantial cost burden to patients and should be considered in perioperative decision-making in elective hand surgery. CLINICAL RELEVANCE Understanding the potential costs related to OON services during a surgical episode, and its drivers, allows surgeons to consider detailed cost discussions during perioperative decision making.

Is Low-value Testing Before Low-risk Hand Surgery Associated With Increased Downstream Healthcare Use and Reimbursements? A National Claims Database Analysis. Clin Orthop Relat Res 2022; 480:1851-1862. [PMID: 35608508 PMCID: PMC9473771 DOI: 10.1097/corr.0000000000002255] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/23/2021] [Accepted: 05/05/2022] [Indexed: 02/04/2023]
Abstract
BACKGROUND Minor hand procedures can often be completed in the office without any laboratory testing. Preoperative screening tests before minor hand procedures are unnecessary and considered low value because they can lead to preventable invasive confirmatory tests and/or procedures. Prior studies have shown that low-value testing before low-risk hand surgery is still common, yet little is known about their downstream effects and associated costs. Assessing these downstream events can elucidate the consequences of obtaining a low-value test and inform context-specific interventions to reduce their use. QUESTIONS/PURPOSES (1) Among healthy adults undergoing low-risk hand surgery, are patients who receive a preoperative low-value test more likely to have subsequent diagnostic tests and procedures than those who do not receive a low-value test? (2) What is the increased 90-day reimbursement associated with subsequent diagnostic tests and procedures in patients who received a low-value test compared with those who did not? METHODS In this retrospective, comparative study using a large national database, we queried a large health insurance provider's administrative claims data to identify adult patients undergoing low-risk hand surgery (carpal tunnel release, trigger finger release, Dupuytren fasciectomy, de Quervain release, thumb carpometacarpal arthroplasty, wrist ganglion cyst, or mass excision) between 2011 and 2017. This database was selected for its ability to track patient claims longitudinally with direct provision of reimbursement data in a large, geographically diverse patient population. Patients who received at least one preoperative low-value test, including complete blood count, basic metabolic panel, electrocardiogram, chest radiography, pulmonary function test, and urinalysis within the 30-day preoperative period, were matched with propensity scores to those who did not. Among the 73,112 patients who met our inclusion criteria (mean age 57 ± 14 years; 68% [49,847] were women), 27% (19,453) received at least one preoperative low-value test and were propensity score-matched to those who did not. Multivariable regression analyses were performed to assess the frequency and reimbursements of subsequent diagnostic tests and procedures in the 90 days after surgery while controlling for potentially confounding variables such as age, sex, comorbidities, and baseline healthcare use. RESULTS When controlling for covariates such as age, sex, comorbidities, and baseline healthcare use, patients in the low-value test cohort had an adjusted odds ratio of 1.57 (95% confidence interval [CI] 1.50 to 1.64; p < 0.001) for a postoperative use event (a downstream diagnostic test or procedure) compared with those who did not have a low-value test. The median (IQR) per-patient reimbursements associated with downstream utilization events in patients who received a low-value test was USD 231.97 (64.37 to 1138.84), and those who did not receive a low-value test had a median of USD 191.52 (57.1 to 899.42) (adjusted difference when controlling for covariates: USD 217.27 per patient [95% CI 59.51 to 375.03]; p = 0.007). After adjusting for inflation, total additional reimbursements for patients in the low-value test cohort increased annually. CONCLUSION Low-value tests generate downstream tests and procedures that are known to provide minimal benefit to healthy patients and may expose patients to potential harms associated with subsequent, unnecessary invasive tests and procedures in response to false positives. Nevertheless, low-value testing remains common and the rising trend in low-value test-associated spending demonstrates the need for multicomponent interventions that target change at both the payer and health system level. Such interventions should disincentivize the initial low-value test and the cascade that may follow. Future work to identify the barriers and facilitators to reduce low-value testing in hand surgery can inform the development and revision of deimplementation strategies.

Abstract
IMPORTANCE Longer time to surgery (TTS) for hip fractures has been associated with higher rates of postoperative complications and mortality. Given that more than 300 000 adults are hospitalized for hip fractures in the United States each year, various improvement programs have been implemented to reduce TTS with variable results, attributed to contextual patient- and system-level factors. OBJECTIVE To catalog TTS improvement programs, identify their results, and categorize program strategies according to Expert Recommendations for Implementing Change (ERIC), highlighting components of successful improvement programs within their associated contexts and seeking to guide health care systems in implementing programs designed to reduce TTS. EVIDENCE REVIEW A systematic review was conducted per the Preferred Reporting Items for Systematic Reviews and Meta-analyses guideline. Three databases (MEDLINE/PubMed, EMBASE, and Cochrane Trials) were searched for studies published between 2000 and 2021 that reported on improvement programs for hip fracture TTS. Observational studies in high-income country settings, including patients with surgical, low-impact, nonpathological hip fractures aged 50 years or older, were considered for review. Improvement programs were assessed for their association with decreased TTS, and ERIC strategies were matched to improvement program components. FINDINGS Preliminary literature searches yielded 1683 articles, of which 69 articles were included for final analysis. Among the 69 improvement programs, 49 were associated with significantly decreased TTS, and 20 programs did not report significant decreases in TTS. Among 49 successful improvement programs, the 5 most common ERIC strategies were (1) assess for readiness and identify barriers and facilitators, (2) develop a formal implementation blueprint, (3) identify and prepare champions, (4) promote network weaving, and (5) develop resource-sharing agreements. CONCLUSIONS AND RELEVANCE In this systematic review, certain components (eg, identifying barriers and facilitators to program implementation, developing a formal implementation blueprint, preparing intervention champions) are common among improvement programs that were associated with reducing TTS and may inform the approach of hospital systems developing similar programs. Other strategies had mixed results, suggesting local contextual factors (eg, operating room availability) may affect their success. To contextualize the success of a given improvement program across different clinical settings, subsequent investigation must elucidate the association between interventional success and facility-level factors influencing TTS, such as hospital census and type, teaching status, annual surgical volume, and other factors.

The relationship between provider age and opioid prescribing behavior. THE AMERICAN JOURNAL OF MANAGED CARE 2022; 28:223-228. [PMID: 35546585 DOI: 10.37765/ajmc.2022.89143] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 06/15/2023]
Abstract
OBJECTIVES The relationship between provider age and quality of care is theoretically indeterminate. Older providers are more experienced, which could lead to a positive relationship between age and quality, but providers' practice patterns could become outdated as technology and scientific knowledge change, which could lead to a negative relationship between age and quality. However, little work has investigated the provider age/quality relationship, and no work has investigated the relationship between provider age and opioid prescribing behavior. STUDY DESIGN We analyze Medicare Part D data to investigate how opioid prescribing differs by provider age. METHODS We use regression analysis to estimate the effect of provider age, holding other factors constant. RESULTS We find that older providers prescribe significantly more opioids, with the gap between older and younger providers increasing from 2010 to 2015. CONCLUSIONS Assuming that older physicians follow patterns of previous generations, anticipated retirement of older providers and entry by younger providers will tend to reduce opioid volumes, undoing at least in part the rapid increase since 2000.

Analysis of Medicare Payments and Patient Outcomes With Pre-Operative Imaging for Carotid Endarterectomy. Ann Vasc Surg 2021; 76:179-184. [PMID: 34153493 DOI: 10.1016/j.avsg.2021.06.001] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2021] [Revised: 05/18/2021] [Accepted: 06/06/2021] [Indexed: 11/29/2022]
Abstract
OBJECTIVE The use of radiographic evaluation of carotid disease may vary, and current guidelines do not strongly recommend the use of cross-sectional imaging (CSI) prior to surgical intervention. We sought to describe the trends in preoperative carotid imaging and evaluate the associated clinical outcomes and Medicare payments for patients undergoing carotid endarterectomy (CEA) for asymptomatic carotid disease. METHODS We used a 20% Medicare sample from 2006 to 2014 identifying patients undergoing CEA for asymptomatic disease. We evaluated preoperative carotid ultrasound and CSI use: CT or MRI of the neck prior to CEA. We calculated average payments of each study from the carrier file and revenue center file. Imaging payments included both the professional component (PC) and the technical component (TC). Claims with a reimbursement of $0 and studies where payment for both the TC and PC could not be identified were excluded from the overall calculation to determine average payment per study. Inpatient reimbursements according to DRG 37-39 were calculated. We compared hospital length of stay (LOS), in hospital stroke, carotid re-exploration, and mortality according to CSI use. RESULTS A total of 58,993 CEAs were identified with pre-operative carotid imaging. The average age was 74.8 ± 7.5 years, and 56.0% were men. A total of 19,678 (33%) patients had ultrasound alone with an average of (2.4 ± 1.9) exams prior to CEA. A total of 39,315 patients underwent CSI prior to CEA with 2.5 ± 2.1 ultrasounds, 0.95 ± 0.86 neck CTs and 0.47 ± 0.7 MRIs per patient. The average payment for ultrasound was $140 ± 40, $282 ± 94 for CT and $410 ± 146 for MRI. The average inpatient reimbursements were $7,413 ± 4,215 for patients without CSI compared with $7,792 ± 3,921 for patients with CSI, P < 0.001. The average LOS during CEA admission was 2.5 ± 3.7days. Patients with CSI had a slightly lower percentage of patients being discharged by postoperative day 2 compared with ultrasound alone (88.9% vs. 91.5%, respectively, P < 0.001). The overall in-hospital stroke rate was 0.38% and carotid re-exploration rate was 1.0% and there was no statistical significant difference between groups. Median follow-up was 3.9 years, and mortality at 8 years was 50% and did not statistically differ between groups. CONCLUSIONS Our analysis found preoperative imaging to include CSI in nearly two-thirds of patients prior to CEA for asymptomatic disease. As imaging and inpatient payments were higher with patients with CSI further work is needed to understand when CSI is appropriate prior to surgical intervention to appropriately allocate healthcare resources.

BACKGROUND Carpal tunnel syndrome is the most common upper-extremity nerve compression syndrome. Over 500,000 carpal tunnel release (CTR) procedures are performed in the U.S. yearly. We estimated the cost-effectiveness of endoscopic CTR (ECTR) versus open CTR (OCTR) using data from published meta-analyses comparing outcomes for ECTR and OCTR. METHODS We developed a Markov model to examine the cost-effectiveness of OCTR versus ECTR for patients undergoing unilateral CTR in an office setting under local anesthesia and in an operating-room (OR) setting under monitored anesthesia care. The main outcomes were costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios (ICERs). We modeled societal (modeled with a 50-year-old patient) and Medicare payer (modeled with a 65-year-old patient) perspectives, adopting a lifetime time horizon. We performed deterministic and probabilistic sensitivity analyses (PSAs). RESULTS ECTR resulted in 0.00141 additional QALY compared with OCTR. From a societal perspective, assuming 8.21 fewer days of work missed after ECTR than after OCTR, ECTR cost less across all procedure settings. The results are sensitive to the number of days of work missed following surgery. From a payer perspective, ECTR in the OR (ECTROR) cost $1,872 more than OCTR in the office (OCTRoffice), for an ICER of approximately $1,332,000/QALY. The ECTROR cost $654 more than the OCTROR, for an ICER of $464,000/QALY. The ECTRoffice cost $107 more than the OCTRoffice, for an ICER of $76,000/QALY. From a payer perspective, for a willingness-to-pay threshold of $100,000/QALY, OCTRoffice was preferred over ECTROR in 77% of the PSA iterations. From a societal perspective, ECTROR was preferred over OCTRoffice in 61% of the PSA iterations. CONCLUSIONS From a societal perspective, ECTR is associated with lower costs as a result of an earlier return to work and leads to higher QALYs. Additional research on return to work is needed to confirm these findings on the basis of contemporary return-to-work practices. From a payer perspective, ECTR is more expensive and is cost-effective only if performed in an office setting under local anesthesia. LEVEL OF EVIDENCE Economic and Decision Analysis Level I.

Abstract
Background Prostate cancer is the most common cancer in men and second leading cause of cancer-related deaths. Changes in screening guidelines, adoption of active surveillance (AS), and implementation of high-cost technologies have changed treatment costs. Traditional cost-effectiveness studies rely on clinical trial protocols unlikely to capture actual practice behavior, and existing studies use data predating new technologies. Real-world evidence reflecting these changes is lacking. Objective To assess real-world costs of first-line prostate cancer management. Design setting and participants We used clinical electronic health records for 2008-2018 linked with the California Cancer Registry and the Medicare Fee Schedule to assess costs over 24 or 60 mo following diagnosis. We identified surgery or radiation treatments with structured methods, while we used both structured data and natural language processing to identify AS. Outcome measurements and statistical analysis Our results are risk-stratified calculated cost per day (CCPD) for first-line management, which are independent of treatment duration. We used the Kruskal-Wallis test to compare unadjusted CCPD while analysis of covariance log-linear models adjusted estimates for age and Charlson comorbidity. Results and limitations In 3433 patients, surgery (54.6%) was more common than radiation (22.3%) or AS (23.0%). Two years following diagnosis, AS ($2.97/d) was cheaper than surgery ($5.67/d) or radiation ($9.34/d) in favorable disease, while surgery ($7.17/d) was cheaper than radiation ($16.34/d) for unfavorable disease. At 5 yr, AS ($2.71/d) remained slightly cheaper than surgery ($2.87/d) and radiation ($4.36/d) in favorable disease, while for unfavorable disease surgery ($4.15/d) remained cheaper than radiation ($10.32/d). Study limitations include information derived from a single healthcare system and costs based on benchmark Medicare estimates rather than actual payment exchanges. Patient summary Active surveillance was cheaper than surgery (-47.6%) and radiation (-68.2%) at 2 yr for favorable-risk disease, which decreased by 5 yr (-5.6% and -37.8%, respectively). Surgery was less costly than radiation for unfavorable risk for both intervals (-56.1% and -59.8%, respectively).

Abstract
In health care, vertical integration - common ownership of producers of complementary services - may have both pro- and anti-competitive effects. We use data on 40 million commercially-insured individuals from the Health Care Cost Institute to construct price indices for office visits to general-practice and specialist physicians for the years 2008-2012. Controlling for generalist market concentration, we find that generalists charge higher prices when they are integrated with specialists, and that the effect of integration is larger in more concentrated specialist markets. Conversely, controlling for specialist market concentration, specialists charge higher prices when integrated with generalists, with larger effects in more concentrated generalist markets. Our results suggest that multispecialty practice enhances physician market power.

Abstract
Despite a vast literature on the determinants of prescription opioid use, the role of health insurance plans has received little attention. We study how the form of Medicare beneficiaries' drug coverage affects the volume of opioids they consume. We find that enrollment in Medicare Advantage, which integrates drug coverage with other medical benefits, significantly reduces beneficiaries' likelihood of filling an opioid prescription, as compared to enrollment in a stand-alone drug plan. Approximately half of this effect was due to fewer fills from prescribers who write a very large number of opioid prescriptions.

Abstract
IMPORTANCE Although surprise medical bills are receiving considerable attention from lawmakers and the news media, to date there has been little systematic study of the incidence and financial consequences of out-of-network billing. OBJECTIVE To examine out-of-network billing among privately insured patients with an inpatient admission or emergency department (ED) visit at in-network hospitals. DESIGN, SETTING, AND PARTICIPANTS A retrospective analysis using data from the Clinformatics Data Mart database (Optum), which includes health insurance claims for individuals from all 50 US states receiving private health insurance from a large commercial insurer was conducted of all inpatient admissions (n = 5 457 981) and ED visits (n = 13 579 006) at in-network hospitals between January 1, 2010, and December 31, 2016. Data were collected and analyzed in March 2019. EXPOSURES Receipt of a bill for care from at least 1 out-of-network physician or medical transport service associated with patient admission or ED visit. MAIN OUTCOMES AND MEASURES The incidence of out-of-network billing and the potential amount of patients' financial liability associated with out-of-network bills from the admission or visit. RESULTS Of 5 457 981 inpatient admissions and 13 579 006 ED admissions between 2010 and 2016, the percentage of ED visits with an out-of-network bill increased from 32.3% to 42.8% (P < .001) during the study period, and the mean (SD) potential financial responsibility for these bills increased from $220 ($420) to $628 ($865) (P < .001; all dollar values in 2018 US$). Similarly, the percentage of inpatient admissions with an out-of-network bill increased from 26.3% to 42.0% (P < .001), and the mean (SD) potential financial responsibility increased from $804 ($2456) to $2040 ($4967) (P < .001). CONCLUSIONS AND RELEVANCE Out-of-network billing appears to have become common for privately insured patients even when they seek treatment at in-network hospitals. The mean amounts billed appear to be sufficiently large that they may create financial strain for a substantial proportion of patients.

The Usability and Feasibility of Conjoint Analysis to Elicit Preferences for Distal Radius Fractures in Patients 55 Years and Older. J Hand Surg Am 2019; 44:846-852. [PMID: 31495523 DOI: 10.1016/j.jhsa.2019.07.010] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/14/2018] [Revised: 05/10/2019] [Accepted: 07/23/2019] [Indexed: 02/02/2023]
Abstract
PURPOSE Eliciting patient preferences is one part of the shared decision-making process-a process of decision making focused on the values and preferences of the patient. We evaluated the usability and feasibility of a point-of-care conjoint analysis tool for preference elicitation for shared decision making in the treatment of distal radius fractures in patients over the age of 55 years. METHODS Twenty-seven patients 55 years of age or older with a displaced distal radius fracture were recruited from a hand and upper extremity clinic. A conjoint analysis tool was created describing the attributes of care (eg, return of grip strength) of surgical and nonsurgical treatment. This tool was administered to patients to determine their preferences for the treatment attributes when choosing between surgical and nonsurgical treatment. Patients completed a System Usability Scale (SUS) to evaluate usability, and time to complete the tool was measured to evaluate feasibility. RESULTS Patients considered the conjoint analysis tool to be usable (SUS, 91.4; SD, 10.9). Mean time to complete the tool was 5.1 minutes (SD, 1.4 minutes). The most important attributes driving the decision for surgical treatment were return of grip strength at 1 year and time spent in a cast or brace. The most important attributes driving the decision for nonsurgical treatment were use of anesthesia during treatment and return of grip strength at 1 year. CONCLUSIONS A point-of-care conjoint analysis tool for distal radius fractures in patients 55 years and older can be used to elicit patient preferences to inform the shared decision-making process. Further investigation evaluating the effect of preference elicitation on treatment choice, involvement in decision making, and patient-reported outcomes are needed. CLINICAL RELEVANCE A conjoint analysis tool is a simple, structured process physicians can use during shared decision making to highlight trade-offs between treatment options and elicit patient preferences to inform treatment choices.

Abstract
PURPOSE The aim of this study was to characterize the demographics, usage patterns and complication rates of clomiphene use in male patients. MATERIALS AND METHODS We retrospectively analyzed male patients from ages 20 to 55 years old who were prescribed clomiphene citrate from 2001 to 2014 using the Truven Health MarketScan, a US claims database. We collected data regarding associated medical diagnoses, diagnostic testing, duration of use, and reported side effects including thrombotic events, vision problems, gynecomastia, mental disorders, liver disease, nausea, or skin problems. RESULTS In total, 12,318 men took clomiphene and represented the primary study cohort, with a mean age of 37.8 years. The percentage of men prescribed clomiphene increased over the study period, as did the average age of clomiphene users. Associated diagnoses included male infertility (52.0%), testicular hypofunction (13.5%), erectile dysfunction (2.4%), and low libido (0.4%). Associated testing included semen analysis (43.7%), testosterone (23.5%), luteinizing hormone (19.3%), and follicle-stimulating hormone (21.1%) levels. The median time of clomiphene use was 3.6 months, with 63% of men stopping within 6 months. No increased risk of reported clomiphene side effects were apparent in men taking the medication. CONCLUSIONS There is a rising prevalence of clomiphene usage without associated adverse side effects in the US. The variability in associated diagnoses, diagnostic testing, and duration of use suggest a need for greater awareness of the proper evaluation and treatment of the men who are prescribed clomiphene.

Abstract
BACKGROUND Total knee arthroplasty is a commonly performed procedure and an important contributor to national health care spending. Reducing the incidence of readmission could have important consequences for patient well-being and relevant financial implications. Whether regional anesthesia techniques are associated with decreased readmission rates and costs among privately insured patients remains unknown. METHODS Using administrative claims data, we identified 138,362 privately insured patients 18-64 years of age who underwent total knee arthroplasty between 2002 and 2013. We then examined whether the use of a nerve block was associated with decreases in readmission rates and related costs during the 90 days after discharge. Our analyses were adjusted for potential confounding variables including medical comorbidities and previous use of opioids and other medications. RESULTS After adjusting for patient demographics, comorbidities, and preoperative medication use, the adjusted 90-day readmission rate was 1.8% (95% confidence interval [CI], 1.1-2.4) among patients who did not receive a block compared to 1.7% (95% CI, 1.1-2.4) among patients who did (odds ratio, 0.99; 95% CI, 0.91-1.09; P = .85). The adjusted readmission-related postoperative cost for patients who did not receive a block was $561 (95% CI, 502-619) and $574 (95% CI, 508-639) for patients who did (difference, $13; 95% CI, -75 to 102; P = .74). This lack of statistically significant differences held for subgroup and sensitivity analyses. CONCLUSIONS Nerve blocks were not associated with improved measures of long-term postoperative resource use in this younger, privately insured study population.

Abstract
OBJECTIVE To estimate the relationship between outcomes of care and medical practices' structure and use of organized care improvement processes. DATA SOURCES/STUDY SETTING We linked Medicare claims data to our national survey of physician practices (2012-2013). Fifty percent response rate; 1,040 responding practices; 31,888 physicians; 868,213 attributed Medicare beneficiaries. STUDY DESIGN Cross-sectional observational analysis of the relationship between practice characteristics and total spending, readmissions, and ambulatory care-sensitive admissions (ACSAs), for all beneficiaries and five categories of beneficiary defined by predicted need for care. PRINCIPAL FINDINGS Practices with 100+ physicians and 50-99 physicians had, respectively, annual spending per high-need beneficiary that was $1,870 (12.5 percent) and $1,824 higher than practices with 1-2 physicians, and readmission rates 1.64 and 1.71 higher. ACSA rates did not vary significantly by practice size. Outcomes did not vary significantly by ownership or by practices' use of organized processes to improve care. CONCLUSIONS Large practices had higher spending and readmission rates than the smallest practices, especially for high-need beneficiaries. There were no significant performance differences between physician-owned and hospital-owned practices. Policy makers should consider the effects of specific policies on provider organization, pending further research to learn which types of practice provide better care.

Abstract
Physician practices have been growing in size, and becoming more commonly owned by hospitals, over time. We use survey data on physician practices surveyed at two points in time, linked to Medicare claims data, to investigate whether changes in practice size or ownership are associated with changes in the use of care management, health information technology (HIT), or quality improvement processes. We find that practice growth and becoming hospital-owned are associated with adoption of more quality improvement processes, but not with care management or HIT. We then investigate whether growth or becoming hospital-owned are associated with changes in Medicare spending, 30-day readmission rates, or ambulatory care sensitive admission rates. We find little evidence for associations with practice size and ownership, but the use of care management practices is associated with lower rates of ambulatory care sensitive admissions.

Abstract
OBJECTIVES To assess whether the characteristics and capabilities of individual practices intending to join the early Medicare accountable care organization (ACO) programs differed from those of practices not intending to join. STUDY DESIGN Data from a 2012-2013 national survey of 1398 physician practices were linked to 2012 Medicare beneficiary claims data to examine differences between practices intending to join a Medicare ACO and practices not intending to join a Medicare ACO. METHODS Differences were examined with regard to patient sociodemographic characteristics and disease burden, practice characteristics and capabilities, and cost and quality measures. Logistic regression was used to examine the differences. RESULTS Practices intending to join were more likely to have better care management capabilities (odds ratio [OR], 1.72; P <.003), health information technology functionality (OR, 1.87; P <.001), and use of quality improvement methods (OR, 1.52; P <.04). They were also more likely to have had prior pay-for-performance experience (OR, 1.59; P <.02) and less likely to be physician-owned (OR, 0.51; P <.001). However, the practices with the greater capabilities still used half or less of them. CONCLUSIONS Physician practices that intended to join the early ACO programs had greater capabilities and experience to manage risk than those practices that decided not to join. The early ACO programs thus attracted the more capable physician practices, but those practices still fell short of implementing key recommended behaviors. The findings have implications for future physician practice selection into ACOs.

Abstract
Managed competition is a concept that was born in California and has achieved a measure of acceptance there. As California and the United States as a whole continue to struggle with the challenge of providing high-quality health care at a manageable cost, it is worth asking whether managed competition-with its tools for harnessing market forces-continues to hold promise as a means of improving value in health care, and whether the standard conceptualization of managed competition should be modified in any way. In this article we reflect on four aspects of California's health care ecosystem that provide insights into these questions: integrated delivery systems, patients' choice of health plans, quality measurement, and new health care marketplace architectures such as Covered California and private insurance exchanges. Overall, while California's experience with managed competition has resulted in some challenges and adaptations, it also gives reason to believe that principles of managed competition continue to have the potential to be a powerful force toward creating a more efficient health care system.

Abstract
This study aims to evaluate whether cancer treatments differ in infertile men compared to men who have undergone vasectomy and age-matched controls. We analyzed subjects from the Truven Health MarketScan Claims database from 2001 to 2009. Infertile men were identified through diagnosis and treatment codes. Comparison groups included vasectomized men and an age-matched cohort who were not infertile and had not undergone vasectomy. We considered cancer types previously associated with infertility that were diagnosed after the diagnosis of infertility. The treatment regimens were determined based on the presence of claims with CPT codes for chemotherapy (CTX), radiation (RTX) or surgical treatment (ST) for each entity in all study groups. Cases with multimodal treatments were also identified. As a result, CTX was similarly distributed among the infertile, vasectomized, and control groups. In contrast, RTX treatment length was shorter in infertile men. The frequency of multimodal treatment (i.e., radiation and chemotherapy) was twofold lower in men with infertility compared to other men. By focusing on treatment patterns for each cancer type among these groups, the duration of RTX and CTX was shorter in infertile men diagnosed with NHL compared to controls. We conclude that Infertile men diagnosed with cancer and specific cancer types experience different treatment courses, with shorter RTX and less combined RTX/CTX compared to fertile and vasectomized men. These differences could reflect differences in stage at presentation, biological behavior, or treatment responses in infertile men.

Abstract
OBJECTIVES To examine the association between annual premiums for health plans available in Federally Facilitated Marketplaces (FFMs) and the extent of competition and integration among physicians and hospitals, as well as the number of insurers. STUDY DESIGN We used observational data from the Center for Consumer Information and Insurance Oversight on the annual premiums and other characteristics of plans, matched to measures of physician, hospital, and insurer market competitiveness and other characteristics of 411 rating areas in the 37 FFMs. METHODS We estimated multivariate models of the relationship between annual premiums and Herfindahl-Hirschman indices of hospitals and physician practices, controlling for the number of insurers, the extent of physician-hospital integration, and other plan and rating area characteristics. RESULTS Premiums for Marketplace plans were higher in rating areas in which physician, hospital, and insurance markets were less competitive. An increase from the 10th to the 90th percentile of physician concentration and hospital concentration was associated with increases of $393 and $189, respectively, in annual premiums for the Silver plan with the second lowest cost. A similar increase in the number of insurers was associated with a $421 decrease in premiums. Physician-hospital integration was not significantly associated with premiums. CONCLUSIONS Premiums for FFM plans were higher in markets with greater concentrations of hospitals and physicians but fewer insurers. Higher premiums make health insurance less affordable for people purchasing unsubsidized coverage and raise the cost of Marketplace premium tax credits to the government.

Abstract
There is ongoing debate about how prices paid to providers by Medicare Advantage plans compare to prices paid by fee-for-service Medicare. We used data from Medicare and the Health Care Cost Institute to identify the prices paid for hospital services by fee-for-service (FFS) Medicare, Medicare Advantage plans, and commercial insurers in 2009 and 2012. We calculated the average price per admission, and its trend over time, in each of the three types of insurance for fixed baskets of hospital admissions across metropolitan areas. After accounting for differences in hospital networks, geographic areas, and case-mix between Medicare Advantage and FFS Medicare, we found that Medicare Advantage plans paid 5.6 percent less for hospital services than FFS Medicare did. Without taking into account the narrower networks of Medicare Advantage, the program paid 8.0 percent less than FFS Medicare. We also found that the rates paid by commercial plans were much higher than those of either Medicare Advantage or FFS Medicare, and growing. At least some of this difference comes from the much higher prices that commercial plans pay for profitable service lines.

Abstract
Objectives To identify trends in concurrent use of a benzodiazepine and an opioid and to identify the impact of these trends on admissions to hospital and emergency room visits for opioid overdose.Design Retrospective analysis of claims data, 2001-13.Setting Administrative health claims database.Participants 315 428 privately insured people aged 18-64 who were continuously enrolled in a health plan with medical and pharmacy benefits during the study period and who also filled at least one prescription for an opioid.Interventions Concurrent benzodiazepine/opioid use, defined as an overlap of at least one day in the time periods covered by prescriptions for each drug. Main outcome measures Annual percentage of opioid users with concurrent benzodiazepine use; annual incidence of visits to emergency room and inpatient admissions for opioid overdose.Results 9% of opioid users also used a benzodiazepine in 2001, increasing to 17% in 2013 (80% relative increase). This increase was driven mainly by increases among intermittent, as opposed to chronic, opioid users. Compared with opioid users who did not use benzodiazepines, concurrent use of both drugs was associated with an increased risk of an emergency room visit or inpatient admission for opioid overdose (adjusted odds ratio 2.14, 95% confidence interval 2.05 to 2.24; P<0.001) among all opioid users. The adjusted odds ratio for an emergency room visit or inpatient admission for opioid overdose was 1.42 (1.33 to 1.51; P<0.001) for intermittent opioid users and 1.81 (1.67 to 1.96; P<0.001) chronic opioid users. If this association is causal, elimination of concurrent benzodiazepine/opioid use could reduce the risk of emergency room visits related to opioid use and inpatient admissions for opioid overdose by an estimated 15% (95% confidence interval 14 to 16).Conclusions From 2001 to 2013, concurrent benzodiazepine/opioid use sharply increased in a large sample of privately insured patients in the US and significantly contributed to the overall population risk of opioid overdose.

[PMID: 27639202 DOI: 10.1016/j.jhealeco.2016.08.006] [Citation(s) in RCA: 38] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/02/2015] [Revised: 08/19/2016] [Accepted: 08/27/2016] [Indexed: 06/06/2023]
Abstract
In this paper, we estimate how hospital ownership of physicians' practices affects their patients' hospital choices. We match data on the hospital admissions of Medicare beneficiaries, including the identity of their physician, with data on the identity of the owner of their physician's practice. We find that a hospital's ownership of a physician dramatically increases the probability that the physician's patients will choose the owning hospital. We also find that patients are more likely to choose a high-cost, low-quality hospital when their physician is owned by that hospital.

Abstract
Although there has been significant interest from health services researchers and policy makers about recent trends in hospitals' ownership of physician practices, few studies have investigated the strengths and weaknesses of available data sources. In this article, we compare results from two national surveys that have been used to assess ownership patterns, one of hospitals (the American Hospital Association survey) and one of physicians (the SK&A survey). We find some areas of agreement, but also some disagreement, between the two surveys. We conclude that full understanding of the causes and consequences of hospital ownership of physicians requires data collected at the both the hospital and the physician level. The appropriate measure of integration depends on the research question being investigated.

The Affordable Care Act reduces emergency department use by young adults: evidence from three States. Health Aff (Millwood) 2016; 33:1648-54.

Abstract
The Affordable Care Act (ACA) extended eligibility for health insurance for young adults ages 19-25. This extension may have affected how young adults use emergency department (ED) care and other health services. To test the impact of the ACA on how young adults used ED services, we used 2009-11 state administrative records from California, Florida, and New York to compare changes in ED use in young adults ages 19-25 before and after the ACA provision was implemented with changes in the same period for people ages 26-31 (the control group). Following implementation of the ACA provision, the younger group had a decrease of 2.7 ED visits per 1,000 people compared to the older group--a relative change of -2.1 percent. The largest relative decreases were found in women (-3.0 percent) and blacks (-3.4 percent). This relative decrease in ED use implies a total reduction of more than 60,000 visits from young adults ages 19-25 across the three states in 2011. When we compared the probability of ever using the ED before and after implementation of the ACA provision, we found a minimal decrease (-0.4 percent) among the younger group compared to the older group. This suggests that the change in the number of visits was driven by fewer visits among ED users, not by changes in the number of people who ever visited the ED.

Abstract
IMPORTANCE Chronic opioid use imposes a substantial burden in terms of morbidity and economic costs. Whether opioid-naive patients undergoing surgery are at increased risk for chronic opioid use is unknown, as are the potential risk factors for chronic opioid use following surgery. OBJECTIVE To characterize the risk of chronic opioid use among opioid-naive patients following 1 of 11 surgical procedures compared with nonsurgical patients. DESIGN, SETTING, AND PARTICIPANTS Retrospective analysis of administrative health claims to determine the association between chronic opioid use and surgery among privately insured patients between January 1, 2001, and December 31, 2013. The data concluded 11 surgical procedures (total knee arthroplasty [TKA], total hip arthroplasty, laparoscopic cholecystectomy, open cholecystectomy, laparoscopic appendectomy, open appendectomy, cesarean delivery, functional endoscopic sinus surgery [FESS], cataract surgery, transurethral prostate resection [TURP], and simple mastectomy). Multivariable logistic regression analysis was performed to control for possible confounders, including sex, age, preoperative history of depression, psychosis, drug or alcohol abuse, and preoperatice use of benzodiazepines, antipsychotics, and antidepressants. EXPOSURES One of the 11 study surgical procedures. MAIN OUTCOMES AND MEASURES Chronic opioid use, defined as having filled 10 or more prescriptions or more than 120 days' supply of an opioid in the first year after surgery, excluding the first 90 postoperative days. For nonsurgical patients, chronic opioid use was defined as having filled 10 or more prescriptions or more than 120 days' supply following a randomly assigned "surgery date." RESULTS The study included 641 941 opioid-naive surgical patients (169 666 men; mean [SD] age, 44.0 [12.8] years), and 18 011 137 opioid-naive nonsurgical patients (8 849 107 men; mean [SD] age, 42.4 [12.6] years). Among the surgical patients, the incidence of chronic opioid in the first preoperative year ranged from 0.119% for Cesarean delivery (95% CI, 0.104%-0.134%) to 1.41% for TKA (95% CI, 1.29%-1.53%) The baseline incidence of chronic opioid use among the nonsurgical patients was 0.136% (95% CI, 0.134%-0.137%). Except for cataract surgery, laparoscopic appendectomy, FESS, and TURP, all of the surgical procedures were associated with an increased risk of chronic opioid use, with odds ratios ranging from 1.28 (95% CI, 1.12-1.46) for cesarean delivery to 5.10 (95% CI, 4.67-5.58) for TKA. Male sex, age older than 50 years, and preoperative history of drug abuse, alcohol abuse, depression, benzodiazepine use, or antidepressant use were associated with chronic opioid use among surgical patients. CONCLUSIONS AND RELEVANCE In opioid-naive patients, many surgical procedures are associated with an increased risk of chronic opioid use in the postoperative period. A certain subset of patients (eg, men, elderly patients) may be particularly vulnerable.

Abstract
172 Background: Little evidence is available to help patients and providers, payers and policymakers find the highest-quality hospitals for cancer surgery. We initiated a groundbreaking effort in California ( www.calqualitycare.org ) to publicly report hospital cancer surgery volume data online. Methods: With financial support from the nonprofit California HealthCare Foundation, we assembled a multidisciplinary team to oversee the project and ensure sound methodology. We obtained existing hospital discharge summary data from the California Office of Statewide Health Planning and Development (OSHPD). We selected cancer surgeries eligible for display through comprehensive review of the literature addressing the association of hospital volume and mortality. We found eleven cancer sites with sufficient evidence of association including bladder, brain, breast, colon, esophagus, liver, lung, pancreas, prostate, rectum, and stomach. Experts advised volume calculation and display of results. Leaders of low volume hospitals were interviewed to understand the reasons for low volume. Results: In 2014, about 60% of cancer surgeries in California were performed at hospitals in the top 20% of volume, but many hospitals performed low numbers of complex procedures, with the per hospital median number of surgeries for esophageal, pancreatic, stomach, liver, or bladder cancer surgeries at 4 or less. Low-volume hospitals included rural and urban hospitals, with small and large bed sizes, and teaching and non-teaching status. At least 670 Californians received cancer surgery at hospitals that performed only one or two surgeries for a particular cancer site; 72% of those patients lived within 50 miles of a top-20% volume hospital. Conclusions: This project demonstrates the potential for public information about hospital volumes to point patients towards high-volume and away from low-volume hospitals. Data regarding 2014 volumes are now available online.

Increased risk of incident chronic medical conditions in infertile men: analysis of United States claims data. Fertil Steril 2015; 105:629-636.

Abstract
OBJECTIVE To determine the incidence of chronic medical conditions of men with infertility. DESIGN Retrospective cohort study. SETTING Not applicable. PATIENT(S) Subjects contained within the Truven Health MarketScan claims database from 2001 to 2009. INTERVENTION(S) Not applicable. MAIN OUTCOME MEASURE(S) The development of chronic medical conditions including hypertension, diabetes, hyperlipidemia, renal disease, pulmonary disease, liver disease, depression, peripheral vascular disease, cerebrovascular disease, heart disease, injury, alcohol abuse, drug abuse, anxiety disorders, and bipolar disorder. RESULT(S) In all, 13,027 men diagnosed with male factor infertility were identified with an additional 23,860 receiving only fertility testing. The average age was 33.1 years for men diagnosed with infertility and 32.8 years for men receiving testing alone. After adjusting for confounding factors, men diagnosed with male factor infertility had a higher risk of developing diabetes (hazard ratio [HR] 1.30, 95% confidence interval [CI] 1.10-1.53), ischemic heart disease (HR 1.48, 95% CI 1.19-1.84), alcohol abuse (HR 1.48, 95% CI 1.07-2.05), and drug abuse (1.67, 95% CI 1.06-2.63) compared with men who only received infertility testing. Similar patterns were identified when comparing those with male factor infertility to vasectomized men. The association between male factor infertility and later health outcomes were strongest for men with longer follow-up. CONCLUSION(S) In this cohort of patients in a national insurance database, men diagnosed with male factor infertility had a significantly higher risk of adverse health outcomes in the years after an infertility evaluation. These findings suggest the overall importance of men's reproductive health and warrant additional investigation to understand the association and identify interventions to improve outcomes for these patients.

Does health plan generosity enhance hospital market power? JOURNAL OF HEALTH ECONOMICS 2015; 44:54-62. [PMID: 26402570 DOI: 10.1016/j.jhealeco.2015.08.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/28/2015] [Revised: 08/05/2015] [Accepted: 08/11/2015] [Indexed: 06/05/2023]
Abstract
We test whether the generosity of employer-sponsored health insurance facilitates the exercise of market power by hospitals. We construct indices of health plan generosity and the price and volume of hospital services using data from Truven MarketScan for 601 counties from 2001 to 2007. We use variation in the industry and union status of covered workers within a county over time to identify the causal effects of generosity. Although OLS estimates fail to reject the hypothesis that generosity facilitates the exercise of hospital market power, IV estimates show a statistically significant and economically important positive effect of plan generosity on hospital prices in uncompetitive markets, but not in competitive markets. Our results suggest that most of the aggregate effect of hospital market structure on prices found in previous work may be coming from areas with generous plans.

Patients' preferences explain a small but significant share of regional variation in medicare spending. Health Aff (Millwood) 2015; 33:957-63.

Abstract
This study assessed the extent to which differences in patients' preferences across geographic areas explained differences in traditional fee-for-service Medicare spending across Dartmouth Atlas of Health Care Hospital Referral Regions (HRRs). Preference measures were based on results of a survey that asked patients questions about their physicians, their own health status, and the care they would want in their last six months of life. We found that patients' preferences explained 5 percent of the variation across HRRs in total Medicare spending. In comparison, supply factors, such as the number of physicians, specialists, and hospital beds, explained 23 percent, and patients' health and income explained 12 percent. We also explored the relative importance of preferences in determining three components of total spending: spending at the end of life, inpatient spending, and spending on physician services. Relative to supply factors, health, and income, patients' preferences explained the largest share of variation in end-of-life spending and the smallest share of variation in spending on physician services. We conclude that variation in preferences contributes to differences across areas in Medicare spending. Medicare policy must consider both supply factors and patients' preferences in deciding how much to accommodate area variation in spending and the extent to which that variation should be subsidized by taxpayers.

Abstract
We examined the consequences of contractual or ownership relationships between hospitals and physician practices, often described as vertical integration. Such integration can reduce health spending and increase the quality of care by improving communication across care settings, but it can also increase providers' market power and facilitate the payment of what are effectively kickbacks for inappropriate referrals. We investigated the impact of vertical integration on hospital prices, volumes (admissions), and spending for privately insured patients. Using hospital claims from Truven Analytics MarketScan for the nonelderly privately insured in the period 2001-07, we constructed county-level indices of prices, volumes, and spending and adjusted them for enrollees' age and sex. We measured hospital-physician integration using information from the American Hospital Association on the types of relationships hospitals have with physicians. We found that an increase in the market share of hospitals with the tightest vertically integrated relationship with physicians--ownership of physician practices--was associated with higher hospital prices and spending. We found that an increase in contractual integration reduced the frequency of hospital admissions, but this effect was relatively small. Taken together, our results provide a mixed, although somewhat negative, picture of vertical integration from the perspective of the privately insured.

Abstract
The emergency department (ED) is the source of most hospital admissions; provides care for patients with no other point of access to the health care system; receives advanced care referrals from primary care physicians; and provides surveillance data on injuries, infectious diseases, violence, and adverse drug events. Understanding the changes in the profile of disease in the ED can inform emergency services administration and planning and can provide insight into the public's health. We analyzed the trends in the diagnoses seen in California EDs from 2005 to 2011, finding that while the ED visit rate for injuries decreased by 0.7 percent, the rate of ED visits for noninjury diagnoses rose 13.4 percent. We also found a rise in symptom-related diagnoses, such as abdominal pain, along with nervous system disorders, gastrointestinal disease, and mental illness. These trends point out the increasing importance of EDs in providing care for complex medical cases, as well as the changing nature of illness in the population needing immediate medical attention.

Abstract
BACKGROUND Drug-eluting stents (DES) have largely replaced bare-metal stents (BMS) for percutaneous coronary intervention (PCI). It is uncertain, however, whether introduction of DES had a significant impact on the comparative effectiveness of PCI versus coronary artery bypass graft surgery (CABG) for death and myocardial infarction (MI). METHODS We identified Medicare beneficiaries aged ≥66 years who underwent multivessel CABG or multivessel PCI and matched PCI and CABG patients on propensity score. We defined the BMS era as January 1999 to April 2003 and the DES era as May 2003 to December 2006. We compared 5-year outcomes of CABG and PCI using Cox proportional hazards models, adjusting for baseline characteristics and year of procedure and tested for a statistically significant interaction (P(int)) of DES era with treatment (CABG or PCI). RESULTS Five-year survival improved from the BMS era to the DES era by 1.2% for PCI and by 1.1% for CABG, and the CABG:PCI hazard ratio was unchanged (0.90 vs 0.90; P(int) = .96). Five-year MI-free survival improved by 1.4% for PCI and 1.1% for CABG, with no change in the CABG:PCI hazard ratio (0.81 vs 0.82; P(int) = .63). By contrast, survival-free of MI or repeat coronary revascularization improved from the BMS era to the DES era by 5.7% for PCI and 0.9% for CABG, and the CABG:PCI hazard ratio changed significantly (0.50 vs 0.57, P(int) ≤ .0001). CONCLUSIONS The introduction of DES did not alter the comparative effectiveness of CABG and PCI with respect to hard cardiac outcomes.

Abstract
IMPORTANCE Physician practice consolidation could promote higher-quality care but may also create greater economic market power that could lead to higher prices for physician services. OBJECTIVE To assess the relationship between physician competition and prices paid by private preferred provider organizations (PPOs) for 10 types of office visits in 10 prominent specialties. DESIGN AND SETTING Retrospective study in 1058 US counties in urbanized areas, representing all 50 states, examining the relationship between measured physician competition and prices paid for office visits in 2010 and the relationship between changes in competition and prices between 2003 and 2010, using regression analysis to control for possible confounding factors. EXPOSURES Variation in the mean Hirschman-Herfindahl Index (HHI) of physician practices within a county by specialty (HHIs range from 0, representing maximally competitive markets, to 10,000 in markets served by a single [monopoly] practice). MAIN OUTCOMES AND MEASURES Mean price paid by county to physicians in each specialty by private PPOs for intermediate office visits with established patients (Current Procedural Terminology [CPT] code 99213) and a price index measuring the county-weighted mean price for 10 types of office visits with new and established patients (CPT codes 99201-99205, 99211-99215) relative to national mean prices. RESULTS In 2010, across all specialties studied, HHIs were 3 to 4 times higher in the 90th-percentile county than the 10th-percentile county (eg, for family practice: 10th percentile HHI = 1023 and 90th percentile HHI = 3629). Depending on specialty, mean price for a CPT code 99213 visit was between $70 and $75. After adjustment for potential confounders, depending on specialty, prices at the 90th-percentile HHI were between $5.85 (orthopedics; 95% CI, $3.46-$8.24) and $11.67 (internal medicine; 95% CI, $9.13-$14.21) higher than at the 10th percentile. Including all types of office visits, price indexes at the 90th-percentile HHI were 8.3% (orthopedics; 95% CI, 5.0%-11.6%) to 16.1% (internal medicine; 95% CI, 12.8%-19.5%) higher. Between 2003 and 2010, there were larger price increases in areas that were less competitive in 2002 than in initially more competitive areas. CONCLUSIONS AND RELEVANCE More competition among physicians is related to lower prices paid by private PPOs for office visits. These results may inform work on policies that influence practice competition.
