  4. Can patient characteristics predict benefit from epidural corticosteroid injections for lumbar spinal stenosis symptoms?

    The Spine Journal 15(11):2319 (2015) PMID 26096484

    Epidural corticosteroid injections are commonly used to treat back and leg pain associated with lumbar spinal stenosis. However, little is known about which patient characteristics may predict favorable responses. The aim was to identify patient characteristics associated with benefits from epid...

    Contemporary Clinical Trials 45(Pt B):157 (2015) PMID 26493088 PMCID PMC4674321

    Diagnostic imaging is often the first step in evaluating patients with back pain and likely functions as a "gateway" to a subsequent cascade of interventions. However, lumbar spine imaging frequently reveals incidental findings among normal, pain-free individuals suggesting that treatment of the...

    Prospective cohort study. To determine whether there are distinct trajectories of back pain and function among older adults and to identify characteristics that distinguish among patients with substantially different prognoses. Although the differential diagnosis and course of low back pain amon...
  7. Short-term improvements in disability mediate patient satisfaction after epidural corticosteroid injections for symptomatic lumbar spinal stenosis.

    Spine 40(17):1363 (2015) PMID 26010037

To identify mediators of the effect of lumbar epidural injections of corticosteroid plus lidocaine on patient satisfaction at 6 weeks postinjection in patients with lumbar spinal stenosis. We hypothesized that short-term...
  8. Clinical outcomes of early and later physical therapist services for older adults with back pain.

    The Spine Journal 15(8):1744 (2015) PMID 25849809

    The timing of physical therapy (PT) services and its association with later function and pain are not clear, especially in older adults. The purpose of this study was to compare clinical outcomes of patients receiving early or later PT services with those not receiving PT among older adults pres...

  10. Problem areas identified as important to older adults with lumbar spinal stenosis.

    The Spine Journal 15(7):1636 (2015) PMID 25791366

    There is growing concern that patient-reported outcomes (PROs) commonly used in clinical research evaluating treatments such as epidural steroid injections (ESIs) for lumbar spinal stenosis may not adequately capture outcomes of greatest importance to older adults. The purpose of the study was t...
  11. Association of early imaging for back pain with clinical outcomes in older adults.

    JAMA 313(11):1143 (2015) PMID 25781443

    In contrast to the recommendations for younger adults, many guidelines allow for older adults with back pain to undergo imaging without waiting 4 to 6 weeks. However, early imaging may precipitate interventions that do not improve outcomes. To compare function and pain at the 12-month follow-up ...
  12. Variation in CT pediatric head examination radiation dose: results from a national survey.

    American Journal of Roentgenology 204(3):W293 (2015) PMID 25714315

    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 abo...
  13. Comparative effectiveness of combined digital mammography and tomosynthesis screening for women with dense breasts.

    Radiology 274(3):772 (2015) PMID 25350548 PMCID PMC4455673

    To evaluate the effectiveness of combined biennial digital mammography and tomosynthesis screening, compared with biennial digital mammography screening alone, among women with dense breasts. An established, discrete-event breast cancer simulation model was used to estimate the comparative clini...
  14. The clinical course of pain and function in older adults with a new primary care visit for back pain.
