Trends in Human Papillomavirus Vaccination in Commercially Insured Children in the United States.

OBJECTIVES: The human papillomavirus (HPV) vaccine was recommended in 2006 for girls and in 2011 for boys. The Healthy People 2020 goal for 2-dose HPV vaccination coverage is 80% by age 15 for girls and boys. We used nationwide population-based data to describe trends in HPV vaccination in children. METHODS: We conducted a cohort study nested within the MarketScan health care database between January 2003 and December 2017. Children were followed from the year they turned 9 until HPV vaccination, insurance disenrollment, or the end of the year when they turned 17, whichever came first. We estimated the cumulative incidence of at least 1- and 2-dose HPV vaccination, stratified by birth year, sex, and state. In secondary analyses, we evaluated the association between state-level vaccination policies and HPV vaccination coverage. RESULTS: This study included 7 837 480 children and 19.8 million person-years. The proportion of 15-year-old girls and boys with at least a 1-dose HPV vaccination increased from 38% and 5% in 2011 to 57% and 51% in 2017, respectively; the proportion with at least a 2-dose vaccination went from 30% and 2% in 2011 to 46% and 39% in 2017, respectively. By 2017, 2-dose HPV vaccination coverage varied from 80% in Washington, District of Columbia, among girls to 15% in Mississippi among boys and was positively correlated with legislation for HPV vaccine education and pediatrician availability. CONCLUSIONS: Despite the increasing trends in uptake, HPV vaccine coverage among commercially insured children in the United States remains behind target levels, with substantial disparities by state.

Current Status and Future Challenges of Liver Transplantation Programs in Chile.

Liver transplantation (LT) was performed for the first time in Chile in 1969, but only since the 1990s has it been systematically performed. Our health system is strongly centralized, which is a severe limitation for the patients who need to be evaluated and subsequently listed. Although proper human and technological resources are available and our results are comparable to international outcomes (overall patient survival at 1, 5, and 10 years of 82%, 70%, and 64%, respectively), we are limited because of a severe scarcity of grafts, which translates into an availability of approximately 7 organs per million persons and a wait-list dropout rate of 40% every year. Thus, our main challenge for the next few years is to improve access to LT among the populations from the extreme regions of the country and overall to improve the availability of grafts by increasing the awareness of physicians in intensive care units and emergency departments, to develop living donor LT programs, to educate the population in order to decrease family refusal, and to reinforce the system of potential donor detection. Although hard work is mandatory for these improvements, none of these tasks seem to be unreachable in the midterm.

Trends in opioid use in commercially insured and Medicare Advantage populations in 2007-16: retrospective cohort study.

OBJECTIVE: To describe trends in the rate and daily dose of opioids used among commercial and Medicare Advantage beneficiaries from 2007 to 2016. DESIGN: Retrospective cohort study of administrative claims data. SETTING: National database of medical and pharmacy claims for commercially insured and Medicare Advantage beneficiaries in the United States. PARTICIPANTS: 48 million individuals with any period of insurance coverage between 1 January 2007 and 31 December 2016, including commercial beneficiaries, Medicare Advantage beneficiaries aged 65 years and over, and Medicare Advantage beneficiaries under age 65 years (eligible owing to permanent disability). MAIN ENDPOINTS: Proportion of beneficiaries with any opioid prescription per quarter, average daily dose in milligram morphine equivalents (MME), and proportion of opioid use episodes that represented long term use. RESULTS: Across all years of the study, annual opioid use prevalence was 14% for commercial beneficiaries, 26% for aged Medicare beneficiaries, and 52% for disabled Medicare beneficiaries. In the commercial beneficiary group, quarterly prevalence of opioid use changed little, starting and ending the study period at 6%; the average daily dose of 17 MME remained unchanged since 2011. For aged Medicare beneficiaries, quarterly use prevalence was also relatively stable, ranging from 11% at the beginning of the study period to 14% at the end. Disabled Medicare beneficiaries had the highest rates of opioid use, the highest rate of long term use, and the largest average daily doses. In this group, both quarterly use rates (39%) and average daily dose (56 MME) were higher at the end of 2016 than the low points observed in 2007 for each endpoint (26% prevalence and 53 MME). CONCLUSIONS: Opioid use rates were high during the study period of 2007-16, with the highest rates in disabled Medicare beneficiaries versus aged Medicare beneficiaries and commercial beneficiaries. Opioid use and average daily dose have not substantially declined from their peaks, despite increased attention to opioid abuse and awareness of their risks.

PSA screening, prostate biopsy, and treatment of prostate cancer in the years surrounding the USPSTF recommendation against prostate cancer screening.

BACKGROUND: The 2012 United States Preventive Services Task Force recommendation against screening for prostate cancer has impacted rates of prostate-specific antigen (PSA) screening and appears to be associated with declining prostate cancer incidence. Our objective was to characterize health care utilization that may explain these observed trends. METHODS: MarketScan claims, which capture >30 million privately insured patients in the United States, were queried for all men aged 40-64 years for the years 2008-2014. PSA testing, prostate biopsy, prostate cancer diagnosis, and definitive local treatment were determined using associated International Classification of Diseases, Ninth Revision and Current Procedural Terminology, Fourth Edition codes. RESULTS: There were approximately 6 million qualifying men with a full year of data. PSA testing, prostate biopsy, and prostate cancer detection declined significantly between 2009 and 2014, most notably after 2011. The prostate biopsy rate per 100 patients with a PSA test decreased over the study period from 1.95 (95% confidence interval [CI], 1.92-1.97) to 1.52 (95% CI, 1.50-1.54). Prostate cancer incidence per prostate biopsy increased over the study period from 0.36 (95% CI, 0.35-0.36) to 0.39 (95% CI, 0.39-0.40). Of new prostate cancer diagnoses, the proportion managed with definitive local treatment decreased from 69% (95% CI, 69%-70%) to 54% (95% CI, 53%-55%). Both PSA testing and prostate cancer incidence decreased significantly after 2011 (P < .001). CONCLUSION: In a large cohort of privately insured men, PSA testing, prostate biopsy, prostate cancer incidence, and local definitive treatment for prostate cancer decreased between 2008 and 2014, most notably after 2011. This decrease may be driven by differential referral patterns from primary care providers to urologists. Cancer 2018;124:2733-2739. © 2018 American Cancer Society.

How Have Health Insurers Performed Financially Under the ACA' Market Rules?

Issue: The Affordable Care Act (ACA) transformed the market for individual health insurance, so it is not surprising that insurers' transition was not entirely smooth. Insurers, with no previous experience under these market conditions, were uncertain how to price their products. As a result, they incurred significant losses. Based on this experience, some insurers have decided to leave the ACA's subsidized market, although others appear to be thriving. Goals: Examine the financial performance of health insurers selling through the ACA's marketplace exchanges in 2015--the market's most difficult year to date. Method: Analysis of financial data for 2015 reported by insurers from 48 states and D.C. to the Centers for Medicare and Medicaid Services. Findings and Conclusions: Although health insurers were profitable across all lines of business, they suffered a 10 percent loss in 2015 on their health plans sold through the ACA's exchanges. The top quarter of the ACA exchange market was comfortably profitable, while the bottom quarter did much worse than the ACA market average. This indicates that some insurers were able to adapt to the ACA's new market rules much better than others, suggesting the ACA's new market structure is sustainable, if supported properly by administrative policy.

Erythropoiesis-stimulating agent use among non-dialysis-dependent CKD patients before and after the trial to Reduce Cardiovascular Events With Aranesp Therapy (TREAT) using a large US health plan database.

BACKGROUND: In a landmark study, TREAT (Trial to Reduce Cardiovascular Events With Aranesp Therapy) examined the use of erythropoiesis-stimulating agent (ESA) therapy to treat anemia among patients with chronic kidney disease (CKD) and found no benefit compared to placebo. STUDY DESIGN: A retrospective observational design was used to determine the impact of TREAT on clinical practice. SETTING & PARTICIPANTS: A large US health plan database with more than 1.2 million claims for patients with non-dialysis-dependent CKD stages 3 and 4. FACTOR: ESA prescribing 2 years before and after publication of TREAT. OUTCOMES: Rate of ESA prescribing for ESA-naive and -prevalent cohorts. MEASUREMENTS: (1) Monthly ESA prescribing in the 2 years before and after publication of TREAT (ordinary least squares regression), (2) adjusted likelihood of prescribing ESA after TREAT (clustered logistic regression), and (3) probability of receiving ESA therapy based on anemia status (χ(2) test). RESULTS: For patients with CKD stage 3, the proportion prescribed ESA therapy declined from 17% pre-TREAT to 11% post-TREAT (a 38% decline), and for those with CKD stage 4, from 34% to 27% (a 22% decline). Prescribing of ESA therapy was declining even before TREAT, but the decline accelerated in the post-TREAT period (stage 3: change of slope, -0.08 [P<0.001]; stage 4: change of slope, -0.16 [P<0.001]). ESA prescribing declined after TREAT regardless of anemia status; among patients with hemoglobin levels <10g/dL, only 25% of patients with CKD stage 3 and 33% of patients with stage 4 were prescribed ESAs 2 years after TREAT, a notable 50% decline. After adjusting for all covariates, the probability of prescribing ESAs was 35% lower during the 2-year period after versus before publication of TREAT (OR, 0.65; 95% CI, 0.63-0.67). LIMITATIONS: The cumulative effect of adverse safety concerns in the period before TREAT also influenced physician prescribing of ESA therapy and could not be separated from the influence of TREAT. CONCLUSIONS: TREAT appears to be a watershed study that was followed by a marked decline in ESA prescribing for patients with CKD.

The growing financial burden of health care: national and state trends, 2001-2006.

The financial burden of health care--the ratio of total out-of-pocket spending for health care services and premiums to total family income--continues to increase nationally. As a result of this trend, more people have been exposed to high costs and lack essential services. This study examines trends nationally and among selected states between 2001 and 2006. The results show considerable state-to-state variation associated mainly with differences in family income and, to a lesser extent, out-of-pocket spending for insurance premiums. Nationally, middle- and higher-income people with private insurance experienced the largest increases in financial burden. Moreover, almost 30 percent of the U.S. population either had a high financial burden of health costs or were uninsured. These facts underscore that escalating health care costs affect all socioeconomic strata, not just the poor.
