ABSTRACT
PURPOSE: Given the increasing prevalence of chronic kidney disease in people with spina bifida, we sought to determine if this is associated with an increase in end stage kidney disease. We examined population based data to measure the frequency of procedures to establish renal replacement therapy-a marker for end stage kidney disease-among patients with spina bifida. MATERIALS AND METHODS: We used the Healthcare Cost and Utilization Project State Inpatient Database and State Ambulatory Surgery and Services Database from Florida, Kentucky, Maryland and New York (2000 to 2014), which include encounter level data. With a diagnosis code based algorithm we identified all procedural encounters made by patients with spina bifida. We determined the percentage of these encounters that were for facilitating renal replacement therapy (ie arteriovenous anastomosis, renal transplantation). We assessed for changes over time in this percentage with the Cochran-Armitage trend test. Bivariate analysis was performed using chi-square test. RESULTS: Of all procedures performed on patients with spina bifida over this time the proportion of procedures performed to establish renal replacement therapy significantly decreased in both the inpatient and outpatient settings (p=0.042 and p <0.001, respectively). People with spina bifida undergoing procedures to establish renal replacement therapy were, on average, young adults (mean age 34.5 and 36.0 years) with a high prevalence hypertension (75.8% of inpatients, 68.6% of outpatients). CONCLUSIONS: The frequency of surgeries to initiate renal replacement therapy among people with spina bifida undergoing procedures is low and is not increasing. This highlights the importance of consistent care throughout adolescence and young adulthood, and hypertension screening.

IMPORTANCE: The benefits of public payment policy may extend to private populations through "spillover" effects. If cost-saving efforts in Medicare also reduce costs among commercially insured patients, Medicare payment systems could be a versatile policy tool in future reform efforts. OBJECTIVES: To determine whether physicians who participated in a Medicare Accountable Care Organization (ACO) reduced spending among their commercial patients. DESIGN: This was a retrospective, longitudinal study which was conducted using Blue Cross Blue Shield of Michigan (BCBSM) claims data from 2010 to 2015. We compared patients seen by physicians who participated in a Medicare ACO to patients whose physicians were not part of an ACO. We used a difference-in-differences (DIDs) design to test whether physician participation in an ACO was associated with reduced spending among their commercially insured patients. We also tested for heterogeneous effects: we assessed whether spillovers were larger among patients with clinical conditions (acute myocardial infarction, pneumonia, congestive heart failure) that have previously been targeted by Medicare payment programs. SETTING: This was a population-based study of commercially insured patients in Michigan. PARTICIPANTS: Patients who experienced a significant clinical episode (eg, labor and delivery, acute myocardial infarction) between 2010 and 2015. EXPOSURE: Our patient-level exposure is treatment by a Medicare ACO-affiliated physician. MAIN OUTCOMES AND MEASURES: Medical spending of 0-90 days and 91-365 days after a clinical episode. RESULTS: Patients in the exposure group (n=54,750) and in the control group (n=137,883) were similar in demographic characteristics of age, sex, and type of clinical episodes. Adjusted mean 90-day spending in the preexposure period was $21,292 among the exposure group and $21,157 among the comparison group; these means declined to $21,250 and $20,995 in the postperiod, yielding a DIDs estimate of $119 [95% confidence interval (CI), -$170 to $408]. Adjusted means for 91-365 days spending in the preperiod were $4258 among the exposure group and $4251 among the comparison group; these means rose to $4338 and $4421 in the postperiod, yielding a DIDs estimate of -$90 (95% CI, -$312 to $132). We also separately examined patients with conditions that have been targeted by other Medicare payment programs. Among these patients, 90-day spending did not differ between exposure and comparison groups (DIDs, -$223; 95% CI, -$2037 to $1591), although 91-365 days spending decreased among the exposure group with marginal statistical significance (DIDs, -$1160; 95% CI, -$2459 to $140). CONCLUSIONS AND RELEVANCE: Physicians who participated in Medicare ACOs did not reduce spending among most of their commercially insured patients. Medicare policy is unlikely to confer significant spillover benefits to the commercially insured population.

BACKGROUND: There are no clinical guidelines on best practices for the use of bronchoscopy and esophagoscopy in diagnosing head and neck cancer. This retrospective cohort study examined variation in the use of bronchoscopy and esophagoscopy across hospitals in Michigan. METHODS: A total of 17,828 patients were identified with head and neck cancer in the 2006 to 2010 Michigan State Ambulatory Surgery Databases. A hierarchical, mixed-effect logistic regression was used to examine whether a hospital's risk-adjusted rate of concurrent bronchoscopy or esophagoscopy was associated with its case volume (< 100, 100-999, or ≥ 1000 cases per hospital) for those undergoing diagnostic laryngoscopy. RESULTS: Of 9218 patients undergoing diagnostic laryngoscopy, 1191 (12.9%) received concurrent bronchoscopy and 1675 (18.2%) underwent concurrent esophagoscopy. The median hospital rate of bronchoscopy was 2.7% (range, 0%-61.1%), and low-volume (odds ratio [OR] = 27.1; 95% confidence interval [CI] = 1.9, 390.7) and medium-volume (OR = 28.1; 95% CI = 2.0, 399.0) hospitals were more likely to perform concurrent bronchoscopy compared to high-volume hospitals. The median hospital rate of esophagoscopy was 5.1% (range, 0%-47.1%), and low-volume (OR = 9.8; 95% CI = 1.5, 63.7) and medium-volume (OR = 8.5; 95% CI = 1.3, 55.0) hospitals were significantly more likely to perform concurrent esophagoscopy relative to high-volume hospitals. CONCLUSIONS: Patients with head and neck cancer who are undergoing diagnostic laryngoscopy are much more likely to undergo concurrent bronchoscopy and esophagoscopy at low- and medium-volume hospitals than at high-volume hospitals. Whether this represents overuse of concurrent procedures or appropriate care that leads to earlier diagnosis and better outcomes merits further investigation.

To evaluate providers' perspectives regarding the delivery of prenatal care to women with psychosocial risk factors. A random, national sample of 2,095 prenatal care providers (853 obstetricians and gynecologists (Ob/Gyns), 270 family medicine (FM) physicians and 972 midwives) completed a mailed survey. We measured respondents' practice and referral patterns regarding six psychosocial risk factors: adolescence (age ≤19), unstable housing, lack of paternal involvement and social support, late prenatal care (>13 weeks gestation), domestic violence and drug or alcohol use. Chi square and logistic regression analyses assessed the association between prenatal care provider characteristics and prenatal care utilization patterns. Approximately 60 % of Ob/Gyns, 48.4 % of midwives and 32.2 % of FM physicians referred patients with psychosocial risk factors to clinicians outside of their practice. In all three specialties, providers were more likely to increase prenatal care visits with alternative clinicians (social workers, nurses, psychologists/psychiatrists) compared to themselves for all six psychosocial risk factors. Drug or alcohol use and intimate partner violence were the risk factors that most often prompted an increase in utilization. In multivariate analyses, Ob/Gyns who recently completed clinical training were significantly more likely to increase prenatal care utilization with either themselves (OR 2.15; 95 % CI 1.14-4.05) or an alternative clinician (2.27; 1.00-4.67) for women with high psychosocial risk pregnancies. Prenatal care providers frequently involve alternative clinicians such as social workers, nurses and psychologists or psychiatrists in the delivery of prenatal care to women with psychosocial risk factors.

BACKGROUND: It is unknown whether changes in study sponsorship have affected the proportion of prospective research on surgery, radiotherapy, and pharmacotherapy for head and neck squamous cell carcinoma (HNSCC) being published over time. PATIENTS AND METHODS: We examined prospective studies from PubMed, Ovid MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials from 1980, 1985, 1990, 1995, 2000, 2005, and 2010. Chi-squared tests were used to identify significant associations between sponsorship and authorship, treatments within study protocols, and presentation of results, whereas time-based trends were analyzed using the Cochran-Armitage test. RESULTS: Among 309 articles, industry (70, 22.7%) and the U.S. government (65, 21%) were the most common sponsors. There was a significant increase in the proportion of industry-sponsored research (p for trend = .013) and a decline in U.S. government-sponsored research (p for trend = .001) over time. The inclusion of surgery in treatment protocols declined over the past four decades (p for trend = .003). Protocols incorporating pharmacotherapy were more likely to have industry support than those without pharmacotherapy (p = .001), whereas protocols with radiotherapy (p = .003) or surgery (p = .002) were less likely to have industry support. CONCLUSION: Industry is the predominant sponsor of prospective HNSCC research, with an emphasis on pharmacotherapy.

Despite expectations that Medicare accountable care organizations (ACOs) would curb health care spending, their effect has been modest. One possible explanation is that ACOs' inability to prohibit out-of-network care limits their control over spending. To examine this possibility, we examined the association between out-of-network care and per beneficiary spending using national Medicare data for 2012-15. While there was no association between out-of-network specialty care and ACO spending, each percentage-point increase in receipt of out-of-network primary care was associated with an increase of $10.79 in quarterly total ACO spending per beneficiary. When we broke down total spending by place of service, we found that out-of-network primary care was associated with higher spending in outpatient, skilled nursing facility, and emergency department settings, but not inpatient settings. Our findings suggest an opportunity for the Medicare program to realize substantial savings, if policy makers developed explicit incentives for beneficiaries to seek more of their primary care within network.

The Medicare Shared Savings Program (MSSP) adjusts savings benchmarks by beneficiaries' baseline risk scores. To discourage increased coding intensity, the benchmark is not adjusted upward if beneficiaries' risk scores rise while in the MSSP. As a result, accountable care organizations (ACOs) have an incentive to avoid increasingly sick or expensive beneficiaries. We examined whether beneficiaries' exposure to the MSSP was associated with within-beneficiary changes in risk scores and whether risk scores were associated with entry to or exit from the MSSP. We found that the MSSP was not associated with consistent changes in within-beneficiary risk scores. Conversely, beneficiaries at the ninety-fifth percentile of risk score had a 21.6 percent chance of exiting the MSSP, compared to a 16.0 percent chance among beneficiaries at the fiftieth percentile. The decision not to upwardly adjust risk scores in the MSSP has successfully deterred coding increases but might discourage ACOs to care for high-risk beneficiaries in the MSSP .

BACKGROUND: Initial evaluations of the Pioneer and Shared Savings Programs have shown modest savings associated with care receipt in a Medicare accountable care organization (ACO). Whether these savings are affected by disease chronicity and the mechanisms through which they occur are unclear. In this context, we examined the association between Medicare ACO implementation and episode spending for 2 different cardiovascular conditions. METHODS AND RESULTS: We analyzed a 20% sample of national Medicare data, identifying fee-for-service beneficiaries aged ≥65 years admitted for acute myocardial infarction (AMI) or congestive heart failure (CHF) between January 2010 and October 2014. We distinguished admissions to hospitals participating in a Medicare ACO from those to hospitals that were not. We calculated 365-day, price-standardized episode spending made on behalf of these beneficiaries, differentiating between early (index admission to 90 days postdischarge) and late payments (91-365 days postdischarge). Using an interrupted time series design, we fit longitudinal multivariable models to estimate the association between hospital ACO participation and episode spending. Our study included 153 476 beneficiaries admitted for AMI to 401 ACO participating hospitals and 2597 nonparticipating hospitals and 260 420 beneficiaries admitted for CHF to 412 ACO participating hospitals and 2796 nonparticipating hospitals. On multivariable analysis, admission to an ACO participating hospital was not associated with changes in early episode spending (AMI, $95 per beneficiary; 95% CI, -$481 to $671; CHF, $158; 95% CI, -$290 to $605). However, it was associated with significant reductions in late episode spending for both cohorts (AMI, -$680; 95% CI, -$1348 to -$11; CHF, -$889; 95% CI, -$1465 to -$313). CONCLUSIONS: For beneficiaries with AMI or CHF, admission to ACO participating hospitals was not associated with changes in early episode spending, but it was associated with significant savings during the late episode. ACO effects on late episode spending may complement other value-based payment reforms that target the early episode.

Growth of an aging US population, coupled with implementation of the Patient Protection and Affordable Care Act, will pose logistical challenges for the primary care provider (PCP) workforce for the foreseeable future. In particular, the burden of otolaryngologic care placed on PCPs is substantial, based on research dating back to the 1970s and confirmed by a recent analysis of the US National Ambulatory Medical Care Survey. Collaboration between the otolaryngology and primary care communities will be needed to ensure that PCPs gain adequate exposure and training in routine otolaryngology care to improve the clinical management of ear, nose, and throat conditions in an expanding population.
