How rural is All of Us? Comparing characteristics of rural participants in the National Institute of Health's All of Us Research Program to other national data sources.

PURPOSE: The National Institute of Health's All of Us Research Program represents a national effort to develop a database to advance health research, especially among individuals historically underrepresented in research, including rural populations. The purpose of this study was to describe the rural populations identified in the All of Us Research Program using the only proxy measure currently available in the dataset. METHODS: Currently, the All of Us Research Program provides a proxy measure of rurality that identifies participants who self-reported delaying care due to far travel distances associated with living in rural areas. Using the All of Us Controlled Tier Dataset v6, we compared sociodemographic and health characteristics of All of Us rural participants identified via this proxy to rural US residents from nationally representative data sources using chi-squared tests. RESULTS: 3.1% of 160,880 All of Us participants were rural, compared to 15%-20% of US residents based on commonly accepted rural definitions. Proportionally more rural All of Us participants reported fair or poor health status, history of cancer, and history of heart disease (P<.01). CONCLUSIONS: The All of Us measure may capture a subset of underserved participants who live in rural areas and experience health care access barriers due to distance. Researchers who use this proxy measure to characterize rurality should interpret their findings with caution due to differences in population and health characteristics using this proxy measure rural compared to other commonly used rural definitions.

Quit Happens: A community clinic-based, multitiered smoking cessation intervention.

OBJECTIVES: To evaluate the "Quit Happens" program launched to reduce tobacco use in low-income populations in a federally qualified nonprofit health center with clinics in Washington and Idaho. Quit Happens was implemented in 2015 and involved a public health nurse, patient, provider, clinic, health system, and community components. DESIGN AND SAMPLE: This smoking cessation program was assessed using a pre-post evaluation design. Nine clinics in a single system of federally qualified nonprofit health centers participated in this program. INTERVENTION: The Quit Happens program was implemented across nine clinics in Washington and Idaho. A specialized public health nurse led the tobacco cessation training of all clinic staff and assisted with development of the smoking cessation program. The 5A model was used as the framework for the training. MEASUREMENTS: The proportion of patients identifying as a current or former smoker was measured using data extracted from electronic health records. RESULTS: Declines in patient reports of currently smoking were observed between 2016 and 2018. The percent of current smokers identified in electronic health records decreased 18.7% and percent of former smokers doubled. CONCLUSION: This community-based tobacco cessation program had wide clinic and community support and self-reported smoking behavior declined over time. A public health nurse's leadership in offering training and program development around tobacco cessation to a local community organization can contribute to reductions in smoking rates.

Hospital factors associated with higher costs in pediatric blunt abdominal trauma: A national study.

BACKGROUND/PURPOSE: Our objective was to evaluate hospital factors, including children's hospital status, associated with higher costs for blunt solid organ pediatric abdominal trauma. METHODS: We queried the 2012 Healthcare Cost and Utilization Project (HCUP) Kid's Inpatient Database (KID) for patients 18 years or younger with low-grade and high-grade blunt abdominal trauma. We calculated total hospital costs and adjusted cost ratios (CR) controlling for patient and hospital-level characteristics. RESULTS: The 2012 KID included 882 low-grade and 222 high-grade pediatric abdominal trauma patients. Median (interquartile range) per hospitalization costs were similar at children's and nonchildren's hospitals for both low-grade (children's = $6575 [$4333-$10,862], nonchildren's $7027 [$4230-$12,219] p = 0.47) and high-grade (children's = $10,984 [$6211- $20,007] nonchildren's $10,156 [$5439-$18,404] p = 0.55) groups. Adjusted cost ratios demonstrated higher costs in the West and among investor owned hospitals for low-grade and high-grade injuries, respectively. Costs at rural hospitals were higher in both groups (low-grade CR = 2.35 95% CI 2.02, 2.74, high-grade CR = 2.78 95% CI 2.13, 3.63) compared to urban teaching hospitals. Cost ratios did not differ based on children's hospital status. CONCLUSION: Hospital costs were similar for children's and nonchildren's hospitals caring for pediatric abdominal trauma. Costs at rural hospitals are higher and may suggest financial instability or nonstandardized care of pediatric trauma patients. LEVEL OF EVIDENCE: III.

Impact of an Advanced Imaging Utilization Review Program on Downstream Health Care Utilization and Costs for Low Back Pain.

BACKGROUND: Early magnetic resonance imaging (MRI) for acute low back pain (LBP) has been associated with increased costs, greater health care utilization, and longer disability duration in workers' compensation claimants. OBJECTIVES: To assess the impact of a state policy implemented in June 2010 that required prospective utilization review (UR) for early MRI among workers' compensation claimants with LBP. RESEARCH DESIGN: Interrupted time series. SUBJECTS: In total, 76,119 Washington State workers' compensation claimants with LBP between 2006 and 2014. MEASURES: Proportion of workers receiving imaging per month (MRI, computed tomography, radiographs) and lumbosacral injections and surgery; mean total health care costs per worker; mean duration of disability per worker. Measures were aggregated monthly and attributed to injury month. RESULTS: After accounting for secular trends, decreases in early MRI [level change: -5.27 (95% confidence interval, -4.22 to -6.31); trend change: -0.06 (-0.01 to -0.12)], any MRI [-4.34 (-3.01 to -5.67); -0.10 (-0.04 to -0.17)], and injection [trend change: -0.12 (-0.06 to -0.18)] utilization were associated with the policy. Radiograph utilization increased in parallel [level change: 2.46 (1.24-3.67)]. In addition, the policy resulted in significant decreasing changes in mean costs per claim, mean disability duration, and proportion of workers who received disability benefits. The policy had no effect on computed tomography or surgery utilization. CONCLUSIONS: The UR policy had discernable effects on health care utilization, costs, and disability. Integrating evidence-based guidelines with UR can improve quality of care and patient outcomes, while reducing use of low-value health services.

Variation in CT pediatric head examination radiation dose: results from a national survey.

OBJECTIVE. The purpose of this article is to examine the variation in radiation dose, CT dose index volume (CTDIvol), and dose-length product (DLP) for pediatric head CT examinations as a function of hospital characteristics across the United States. MATERIALS AND METHODS. A survey inquiring about hospital information, CT scanners, pediatric head examination protocol, CTDIvol, and DLP was mailed to a representative sample of U.S. hospitals. Follow-up mailings were sent to nonrespondents. Descriptive characteristics of respondents and nonrespondents were compared using design-based Pearson chi-square tests. Dose estimates were compared across hospital characteristics using Bonferroni-adjusted Wald test. Hospital-level factors associated with dose estimates were evaluated using multiple linear regressions and modified Poisson regression models. RESULTS. Surveys were sent out to 751 hospitals; 292 responded to the survey, of which 253 were eligible (35.5% response rate, calculated as number of hospitals who completed surveys [n = 253] divided by sum of number who were eligible and initially consented [n = 712] plus estimated number who were eligible among those who refused [n = 1]). Most respondents reported using MDCT scanners (99.2%) and having a dedicated pediatric head CT protocol (93%). Estimated mean reported CTDIvol values were 27.3 mGy (95% CI, 24.4-30.1 mGy), and DLP values were 390.9 mGy × cm (95% CI, 346.6-435.1 mGy × cm). These values did not vary significantly by region, trauma level, teaching status, CT accreditation, number of CT scanners, or report of a dedicated pediatric CT protocol. However, estimated CTDIvol reported by children's hospitals was 19% lower than that reported by general hospitals (p < 0.01). CONCLUSION. Most hospitals (82%) report doses that meet American College of Radiology accreditation levels. However, [corrected] the mean CTDI(vol) at children's hospitals was approximately 7 mGy (21%, adjusted for covariates), lower than that at nonchildren's hospitals.

Hospital-level factors associated with use of pediatric radiation dose-reduction protocols for head CT: results from a national survey.

OBJECTIVES: To examine hospital-level factors associated with the use of a dedicated pediatric dose-reduction protocol and protective shielding for head CT in a national sample of hospitals. METHODS: A mixed-mode (online and paper) survey was administered to a stratified random sample of US community hospitals (N = 751). Respondents provided information on pediatric head CT scanning practices, including use of a dose-reduction protocol. Modified Poisson regression analyses describe the relative risk (RR) of not reporting the use of a pediatric dose-reduction protocol or protective shielding; multivariable analyses adjust for census region, trauma level, children's hospital status, and bed size. RESULTS: Of hospitals that were contacted, 38 were ineligible (no CT scanner, hospital closed, do not scan infants), 1 refused, and 253 responded (35.5% response rate). Across all hospitals, 92.6% reported using a pediatric dose-reduction protocol. Modified Poisson regression showed that small hospitals (0-50 beds) were 20% less likely to report using a protocol than large hospitals (>150 beds) (RR: 0.80, 95% confidence interval [CI]: 0.65-0.99; adjusted for covariates). Teaching hospitals were more likely to report using a protocol (RR: 1.10, 95% CI: 1.02-1.19; adjusted for covariates). After adjusting for covariates, children's hospitals were significantly less likely to report using protective shielding than nonchildren's hospitals (RR: 0.64, 95% CI: 0.56-0.73), though this may be due to more advanced scanner type. CONCLUSION: Results from this study provide guidance for tailored educational campaigns and quality improvement interventions to increase the adoption of pediatric dose-reduction efforts.

Health care utilization and costs associated with adherence to clinical practice guidelines for early magnetic resonance imaging among workers with acute occupational low back pain.

OBJECTIVE: To estimate health care utilization and costs associated with adherence to clinical practice guidelines for the use of early magnetic resonance imaging (MRI; within the first 6 weeks of injury) for acute occupational low back pain (LBP). DATA SOURCES: Washington State Disability Risk Identification Study Cohort (D-RISC), consisting of administrative claims and patient interview data from workers' compensation claimants (2002-2004). STUDY DESIGN: In this prospective, population-based cohort study, we compared health care utilization and costs among workers whose imaging was adherent to guidelines (no early MRI) to workers whose imaging was not adherent to guidelines (early MRI in the absence of red flags). DATA COLLECTION/EXTRACTION METHODS: We identified workers (age>18) with work-related LBP using administrative claims. We obtained demographic, injury, health, and employment information through telephone interviews to adjust for baseline differences between groups. We ascertained health care utilization and costs from administrative claims for 1 year following injury. PRINCIPAL FINDINGS: Of 1,770 workers, 336 (19.0 percent) were classified as nonadherent to guidelines. Outpatient and physical/occupational therapy utilization was 52-54 percent higher for workers whose imaging was not adherent to guidelines compared to workers with guideline-adherent imaging; utilization of chiropractic care was significantly lower (18 percent). CONCLUSIONS: Nonadherence to guidelines for early MRI was associated with increased likelihood of lumbosacral injections or surgery and higher costs for out-patient, inpatient, and nonmedical services, and disability compensation.
