Background: Medicare reimbursement is known to exhibit geographic variation for inpatient orthopedic procedures. This study determined whether US geographic variations also exist for commonly performed hand surgeries. Methods: Using the Medicare Provider Utilization and Payment Data (2012-2013) from Centers for Medicare & Medicaid Services, we analyzed regional physician charges/payments for common outpatient hand surgeries. Results: The most commonly performed procedures in the United States were open carpal tunnel release (n = 21 944), trigger finger release (n = 15 345), endoscopic carpal tunnel release (n = 7106), and basal joint arthroplasty/ligament reconstruction and tendon interposition (n = 2408). A range of average Medicare physician reimbursements existed based on geographic region for basal joint arthroplasty ($669-$571), endoscopic carpal tunnel release ($400-$317), open carpal tunnel release ($325-$261), and trigger finger release ($215-$167). The latter three exhibited statistically significant variation across geographic regions with regard to both charges and physician reimbursement. However, the overall percentage physician reimbursement (70%-79%) to charges was similar across all geographic regions. Conclusions: In conclusion, further research is warranted to determine why regional or geographic variations in physician payments exist in the United States for commonly performed hand surgeries.

Waldenström's Macroglobulinemia

Abstract Background: Waldenstrom’s Macroglobulinemia (WM) is an uncommon subtype of B cell malignancy. The updated trend of its incidence in the United States has not been reported. Objective: To better understand the incidence and epidemiological features of WM in the United States. Methods: We conducted a population-based incidence study with 1463 patients (pts) with WM identified from the Surveillance, Epidemiology, and End Results (SEER) tumor registries over 17 years. From the SEER data, 78,558 pts of all ages diagnosed with non-Hodgkin’s lymphoma (NHL) were identified between 1988 and 2004 in 9 SEER areas. Of these pts, 1463 had pathologically confirmed WM, accounting for 2% of NHL. The incidence with 95% confidence intervals were generated from SEER*Stat Software and was age-adjusted to the U.S. year 2000 standard population. Annual Percent Change (APC)for the incidence was calculated and considered to be statistically significant if p value was less than 0.05. The crude 1-year survival rate was calculated as the ratio of the number of pts who survived over 1 year and the number of pts diagnosed with WM. Results: Of the1463 pts with WM, median age at diagnosis was 73. Overall incidence rate was 0.37/100,000/year, which increased with age from 0.03 in pts aged <50 to 1.03 in pts aged 60–69 and 2.76 in pts aged 80 or older. The age-adjusted incidence did not change significantly from 0.34 in 1988 compared with 0.36 in 2004. Therefore was no significant Annual Percent Change (0.97%, p>0.05). Incidence of WM was higher in men (0.52) than in women (0.26) (P<0.001). There were substantial geographic variations (p<0.001) in the incidence of WM. The age-adjusted incidence was highest in Seattle (0.49) and lowest in Atlanta (0.19). The incidence was higher in Caucasians (0.40) than in African-Americans (0.17) and other races (0.20). Annual Percentage Change was 1.3% in Caucasians (p<0.05). Conclusion: The overall incidence of Waldenstrom’s Macroglobulinemia did not change significantly from 1988 to 2004, and was significantly higher in male Caucasians. There were substantial geographical variations in the incidence of Waldenstrom’s Macroglobulinemia in the United States.

The Relationship

Among the myriad collateral consequences of the high level of incarceration in the United States is its detrimental effects on public health. Just as there are geographic variations in level of incarceration within the United States, so too are there variations in health outcomes. This study examines the relationship between incarceration rates and population health for a national sample of counties from 2015, with a focus on how this relationship is influenced by both region (South vs. non-South) and whether a jurisdiction is rural. To obtain unbiased estimates of the effect of incarceration rates on two alternate health outcomes, it employs two-stage least-squares modeling, which accounts for the endogeneity of incarceration rates when determining their effect on population health. Results indicate that level of incarceration has a detrimental effect on both mortality (i.e., premature death) and morbidity (i.e., self-reported health), and that these effects are more pronounced in rural and Southern counties. Implications of these findings for both policy and research are considered.

Breastfeeding Practices

Background: To better track progress in achieving the Healthy People 2020 goals, the Centers for Disease Control and Prevention (CDC) publishes an annual Breastfeeding Report Card (BRC) that represents a compilation of data on breastfeeding practices in all states. With data drawn from the CDC National Immunization Survey, the BRC provides an especially valuable source of information about geographic trends in breastfeeding and related support activities. Research aim: This study aimed to identify important geographic trends in both breastfeeding practices and support structures in the United States, highlighting their spatial disparities. Methods: Exploratory spatial data analysis, including local indicators of spatial association, is combined with spatial regression models to highlight geographic variations in breastfeeding practices and support. Results: Geographic variation in both breastfeeding practices and allied support exists within the United States. Geographic hot spots of breastfeeding are found in the western and northeastern sections of the United States, and cool spots are located primarily in the Southeast. Regression results suggested that unemployment and demographic diversity are negatively associated with breastfeeding rates, whereas higher education and the presence of International Board Certified Lactation Consultants® (IBCLCs®) are positively connected to persistent breastfeeding practices. Further, although the availability of professional support (IBCLC) strengthened nationwide between 2011 and 2016, the availability of mother-to-mother support (La Leche League) softened. Conclusion: Although breastfeeding initiation rates continue to increase in the United States, rates of exclusive breastfeeding at 3 and 6 months remain low, displaying significant geographic variation. The ability to pinpoint lagging regions can help to efficiently allocate additional breastfeeding support resources and interventions.
