Comparing the clinical outcomes of lumbar transforaminal vs interlaminar epidural steroid injections in a registry cohort.

Background: Transforaminal and interlaminar approaches are both common means of performing epidural steroid injection. Comparative effectiveness data on outcomes of these approaches is available but has yielded mixed results. Objective: Compare the effect of transforaminal vs interlaminar delivery of epidural steroids on patient-reported pain severity. Design: Retrospective Cohort Study. Methods: A retrospective review of prospectively collected interventional spine procedure registry data between December 2011 and July 2017 from a single academic medical center. Those who received epidural steroid injections and had prospectively collected index pain data (11-point Numeric Rating Scale [NRS]) recorded in the patient's chart prior to the procedure and at a 3 month follow up appointment were included. The outcome of interest was ≥50% reduction in pain as measured using a NRS for back and/or leg pain. To evaluate true predictive odds of success, multivariable logistic regression modeling was used to determine the odds of achieving improved pain. Results: Of the 73 patients included in the study, 61 (84%) reported radicular pain, 49 (67%) reported back pain, and eleven (15%) had symptoms consistent with claudication, pain characteristics were not mutually exclusive. Fifty-one (70%) underwent transforaminal epidural steroid injection, while 22 (30%) underwent interlaminar injection. When claudication and radicular pain groups were combined into a single "leg pain" category (n = 66), 26/46 (57% 95% CI 41-71%) patients undergoing transforaminal and 6/20 (30% 95% CI 12-54%) patients undergoing interlaminar injections achieved ≥50% leg pain reduction on NRS (p = 0.048). Transforaminal epidural steroid injections were associated with higher odds of ≥50% reduction in leg pain in both the unadjusted model (OR 3.2, p = 00.034) and after adjustment for presence of radicular pain on presentation and the type of steroid used (OR 3.6, p = 0.042). Conclusion: In this clinical practice registry, patients treated with transforaminal epidural steroid injection were more likely to achieve ≥50% reduction in radicular or neurogenic/claudicatory leg pain compared to those treated with interlaminar epidural steroid injection.

The association between preoperative epidural steroid injections and postoperative cervical and lumbar surgical site infections: A systematic review and meta-analysis.

Background: Is there a statistically significant association between preoperative epidural steroid injections (ESI) and postoperative cervical and lumbar spinal surgery infections (SSI)? Methods: A systematic review and meta-analysis was completed of patients 18 years or older who underwent elective cervical or lumbar spinal surgery. Those who underwent surgery with preoperative ESI were compared to those without. We assessed for differences in postoperative SSI incidence. Electronic literature databases were searched through October 2022. Peer-reviewed publications that included raw data regarding epidural exposure and non-exposure were included. Case reports, case series, abstracts, editorials, or publications that did not include raw data were excluded. Odd's ratios (OR) were calculated from the raw data collected. Meta-analysis was done using RevMan v5 with a fixed effects model. Results: We identified 16 articles for inclusion. When not controlling for the type of surgery and time from ESI to surgery, there was a statistically significant OR between preoperative ESI and postoperative SSI. The association persisted when the ESI was performed within 30 days or 31-90 days of the surgery. No association was discovered when evaluating only cervical spine surgeries. The evidence is assigned a "moderate" GRADE rating. Conclusions: Our analysis shows a small, time-dependent, statistically significant association between preoperative ESI and postoperative lumbar SSI may exist. However, the OR produced, while statistically significant, are close enough to 1.0 that clinically, the effect size is "small." The number needed to treat for an ESI in the appropriate clinical setting is, at worst, 3. The number needed to harm, meaning the number of patients who undergo an ESI at any time before their spine surgery and then develop a SSI, is 111 patients. Ultimately, the surgical sparing potential from an ESI outweighs the SSI risk based on our findings.

Current trends in the technical performance of lumbar zygapophyseal joint interventions.

Objective: To survey how interventional pain physicians are currently performing lumbar facet interventions, with an emphasis on fellowship training. Design: Survey Study. Methods: An online electronic survey disseminated via Research Electronic Data Capture (REDCap) software to current and expired attending physician members of the Spine Intervention Society (SIS). Responses were stratified by fellowship training type: ACGME Pain Medicine (APM), ACGME Sports Medicine (ASM), Interventional Spine and Musculoskeletal Medicine (ISMM), or None. Results: As a whole, a majority of respondents indicated on independent questions they require 2 diagnostic medial branch blocks (MBBs) performed with 0.5 â€‹cc or less of anesthetic to result in at least 75% pain relief before proceeding with a radiofrequency neurotomy (RFN), performed via parallel approach with 18g or larger needle and 10 â€‹mm active tip and a lesion of at least 80-85° C and 90-119 â€‹s of duration. Statistically significant differences as stratified by APM vs ISMM fellowship training included: the use of corticosteroids at the time of RFN (43/79 (54.4%) vs 16/63 (25.4%), typically treating 3 segments or more 22/79 (27.8%) vs 7/73 (9.6%), and MBB volume injectate of ≥ 1 â€‹cc 22/79 (27.8%) vs 7/63 (11.1%) respectively. Conclusions: There is largely agreement upon the technical performance of lumbar facet interventions by members of SIS. Physicians who completed an APM fellowship were more likely to report using corticosteroids at the time of RFN, using higher anesthetic volumes and treating 3 or more spinal segments.

Bullying, Discrimination, Harassment, Sexual Harassment, and the Fear of Retaliation During Surgical Residency Training: A Systematic Review.

BACKGROUND: The negative effects of bullying, discrimination, harassment, and sexual harassment (BDHS) on well-being and productivity of surgical residents in training have been well documented. Despite this, little has changed over the past decade and these behaviors continue. The purpose of this study was to determine the prevalence of each abusive behavior experienced by residents, identify the perpetrators, and examine the reporting tendency. METHODS: A systematic review of articles published between 2010 and 2020 in the MEDLINE, EMBASE, and Cochrane databases was performed following PRISMA guidelines. The following search terms were used: bullying, harassment, sexual harassment, discrimination, abuse, residency, surgery, orthopedic surgery, general surgery, otolaryngology, obstetrics, gynecology, urology, plastic surgery, and training. RESULTS: Twenty-five studies with 29,980 surgical residents were included. Sixty-three percent, 43, 29, and 27% of surgical residents experienced BDHS, respectively. Female residents reported experiencing all BDHS behaviors more often. Thirty-seven percent of resident respondents reported burnout, and 33% reported anxiety/depression. Attending surgeons, followed by senior co-residents, were the most common perpetrators. Seventy-one percent did not report the behavior to their institution. Fifty-one percent stated this was due to fear of retaliation. Of those who reported their experiences, 56% stated they had a negative experience reporting. CONCLUSION: Our review demonstrates high prevalence rates of BDHS experienced by residents during surgical training, which have been associated with burnout, anxiety, and depression. The majority of residents did not report BDHS due to fear of retaliation. Residency programs need to devise methods to have a platform for residents to safely voice their complaints.

Development and Implementation of an International Virtual Didactic Series for Physical Medicine and Rehabilitation Graduate Medical Education During COVID-19.

ABSTRACT: Coronavirus disease of 2019 presented significant challenges to residency and fellowship programs. Didactic lectures were particularly affected as redeployment of faculty and trainees, limitations on in-person gathering, and other barriers limited opportunities for educational engagement. We sought to develop an online didactic series to address this gap in graduate medical education.Lecturers were recruited via convenience sample and from previous Association of Academic Physiatrists presenters from across the United States and Canada; these presented via Zoom during April and May 2020. Lecturers and content reflected the diverse nature of the specialty. Learning objectives were adapted from the list of board examination topics provided by the American Board of Physical Medicine and Rehabilitation.Fifty-nine lectures were presented. Maximum concurrent live viewership totaled 4272 and recorded lecture viewership accounted for an additional 6849 views, for a total of at least 11,208 views between the date of the first lecture (April 9, 2020) and May 1, 2021. Live viewers of one of the lectures reported participating from several states and 16 countries.The Association of Academic Physiatrists-led virtual didactics augmented graduate medical education during the coronavirus disease of 2019 pandemic, and data confirm that the lectures have continued to enjoy a high level of viewership after the cessation of live lectures.

The interrater reliability of the novel Udby classification of Modic Changes: A first estimate.

Background: Modic change grading is heterogeneous, inconsistent, and lacks a single nomenclature across the published literature. A new method of Modic change classification has been established by Dr. Peter Udby which hopes to unify how Modic changes are classified while also adding grading of the cranial/caudal extent of the Modic change across the vertebral body from the respective endplate involved to best capture the clinically relevant information of Modic changes. Methods: Twenty magnetic resonance images of potential basivertebral nerve ablation candidates were independently reviewed by two board-certified and fellowship trained neuroradiologist and two board-certified and fellowship-trained interventional spine physiatrists for the presence and characterization of Modic changes using the newly described Udby classification. 100% agreement of all four reviewers of Modic change presence, Type, and Udby classification was required to be classified as agreement. There were 480 total data points each with 10 unique choices to compare across the four independent reviewers. Results: The kappa value of their agreement was 0.5899 (95% CI 0.4860-0.6939). Conclusion: This study, requiring unanimous agreement between 4 physicians in application of the Udby classification, demonstrated an interrater reliability score of 0.5899 (95% CI 0.4860-0.6939). While this figure provides a first estimate, larger scale research is necessary before definitive claims regarding the interrater agreement validity of the Udby characterization system may be made.

Characteristics of ambulatory spine care visits in the United States, 2009-2016.

BACKGROUND: Back pain is a leading reason for seeking care in the United States (US), and is a major cause of morbidity. OBJECTIVE: To analyze demographic, patient, and visit characteristics of adult ambulatory spine clinic visits in the United States from 2009-2016. METHODS: Data from the National Ambulatory Medical Care Survey from 2009-2016 were used and were sample weighted. RESULTS: Most patients presenting for ambulatory spine care were 45-64 years (45%), were most commonly female (56.8%), and private insurance (45%) and Medicare (26%) were most common payors. The percentage of visits for spine care done at a primary care setting was 50.1% in 2009-2010 and 48.3% in 2014-2015. Approximately 15.5% were seen in orthopedic surgery clinics in 2009-2010 and 7.3% in 2015-2016. MRI was utilized in 11.7% in 2009-2010 and 11.0% in 2015-2016. Physical therapy was prescribed in 13.2% and narcotic analgesic medications were prescribed in 36.2% of patients in 2015-2016. CONCLUSIONS: MRI was used more frequently than guidelines recommended, and physical therapy was less frequently utilized despite evidence. A relatively high use of opiates in treatment of back pain was reported and is concerning. Although back pain represents a substantial public health burden in the United States, the delivery of care is not evidence-based.

The Effectiveness of Intraosseous Basivertebral Nerve Radiofrequency Neurotomy for the Treatment of Chronic Low Back Pain in Patients with Modic Changes: A Systematic Review.

OBJECTIVE: Determine the effectiveness of intraosseous basivertebral nerve radiofrequency neurotomy for the treatment of chronic low back pain with type 1 or 2 Modic changes. DESIGN: Systematic review. POPULATION: Persons aged ≥18 years with chronic low back pain with type 1 or 2 Modic changes. INTERVENTION: Intraosseous basivertebral nerve radiofrequency neurotomy. COMPARISON: Sham, placebo procedure, active standard care treatment, or none. OUTCOMES: The primary outcome of interest was the proportion of individuals with ≥50% pain reduction. Secondary outcomes included ≥10-point improvement in function as measured by Oswestry Disability Index as well as ≥2-point reduction in pain score on the Visual Analog Scale or Numeric Rating Scale, and decreased use of pain medication. METHODS: Three reviewers independently assessed publications before May 15, 2020, in MEDLINE and Embase and the quality of evidence was evaluated using the Grades of Recommendation, Assessment, Development, and Evaluation framework. RESULTS: Of the 725 publications screened, seven publications with 321 participants were ultimately included. The reported 3-month success rate for ≥50% pain reduction ranged from 45% to 63%. Rates of functional improvement (≥10-point Oswestry Disability Index improvement threshold) ranged from 75% to 93%. For comparison to sham treatment, the relative risk of treatment success defined by ≥50% pain reduction and ≥10-point Oswestry Disability Index improvement was 1.25 (95% confidence interval [CI]: .88-1.77) and 1.38 (95% CI: 1.10-1.73), respectively. For comparison to continued standard care treatment the relative risk of treatment success defined by ≥50% pain reduction and ≥10-point Oswestry Disability Index improvement was 4.16 (95% CI: 2.12-8.14) and 2.32 (95% CI: 1.52-3.55), respectively. CONCLUSIONS: There is moderate-quality evidence that suggests this procedure is effective in reducing pain and disability in patients with chronic low back pain who are selected based on type 1 or 2 Modic changes, among other inclusion and exclusion criteria used in the published literature to date. Success of the procedure appears to be dependent on effective targeting of the BVN. Non-industry funded high-quality, large prospective studies are needed to confirm these findings.

Factors Influencing Fellowship Decision Making During Physical Medicine & Rehabilitation Residency.

ABSTRACT: Previous surveys have demonstrated an increasing trend among graduating physiatry residents who desired to pursue a subspecialty fellowship. There has been sparse information on whether residents start their training with a subspecialty interest in mind and what factors influenced them to choose a fellowship. This article describes a prospective survey in the 2019-2020 academic year in which 175 responses were collected representing 65 (78.3%) of the 83 physical medicine and rehabilitation programs with graduating residents. Nearly 3 in 4 (73.7%, 129/175) reported matching into a fellowship, and among those, 79.8% (103/129) had matched into a pain, spine, or sports medicine fellowship. At the start of residency, 62.3% (109/175) were planning to pursue a fellowship, with 54.9% (96/175) planning to focus on either pain, sports, or spine medicine. Most respondents (72.2%) did not change their initial subspecialty focus during their residency training. Forty-six percent agreed that their anticipated subspecialty influenced their choice of residency program. The results of this survey demonstrate that most graduating residents are matriculating into fellowship training with pain, spine, and/or sports medicine being among the top choices. These results underscore the importance of subspecialty interests of trainees at the start of their residency and how training may influence their subspecialty interest.

Effect of Microfracture on Functional Outcomes and Subchondral Sclerosis Following Distraction Arthroplasty of the Ankle Joint.

BACKGROUND: Treatment for post-traumatic osteoarthritis (PTOA) of the ankle remains challenging. Distraction arthroplasty (DA) is an alternative for patients who are averse to or poor candidates for arthrodesis or joint replacement. The purpose of this study was to examine the role of microfracture (MFX) and concentrated bone marrow aspirate (CBMA) on the outcome of patients undergoing DA for end-stage PTOA of the ankle joint. METHODS: Ninety-five patients who underwent DA for the treatment of end stage PTOA from 2009 to 2014 were selected from the hospital ankle registry. Demographic data, functional activity levels, complications, and radiographs taken at 6, 12, 24, and 36 months postoperatively were reviewed. Foot and Ankle Outcome Scores (FAOS) were obtained at the same time intervals. A total of 78 patients were included in this study. Interventions were divided into 4 groups for comparison: DA+MFX (n = 8), DA+MFX+CBMA (n = 35), DA+CBMA (n = 22), and DA alone (n = 13). RESULTS: Patients undergoing DA+MFX or DA+MFX+CBMA had significantly worse motion (P = .003) when compared with DA alone. Patients undergoing MFX had significantly reduced postoperative joint space and a greater length of time to return to activity when compared to subgroups not using MFX (P = .01). The use of MFX was associated with significantly lower FAOS scores. CONCLUSION: The current study showed no benefit from MFX when combined with DA in the treatment of PTOA. CBMA may have helped mitigate the adverse effect of MFX but conferred no benefit when used with DA alone. DA remains a useful alternative to ankle arthrodesis and arthroplasty in patients with PTOA. However, MFX and biologic augmentation using CBMA appeared to have no additional benefit. LEVEL OF EVIDENCE: Level III, comparative study.

Overactive bladder in an integrated delivery system: a longitudinal cohort study.

BACKGROUND: Overactive bladder (OAB) is common and morbid. Medication and diagnosis claims may be specific, but lack sensitivity to identify patients with overactive bladder. We used an "electronic health record (EHR) phenotype" to identify cases and describe treatment choices and anticholinergic burden for OAB. METHODS: We conducted a retrospective cohort study in a large, integrated health delivery system between July 2011 and June 2012 (2-year follow-up). We examined care from primary care and specialty clinics, medication and procedure use, and anticholinergic burden for each patient. RESULTS: There were 7362 patients with an EHR OAB phenotype; 50% of patients were > 65 years old, 74% were female, and 83% were white. The distribution of care included primary care physician (PCP)/specialty co-management (25% of patients); PCP care only (18%); urology only (13%); or some other combination of specialty care (33%). Only 40% of patients were prescribed at least 1 OAB medication during the study. The mean duration of prescribed medication was 1.5 months (95% confidence interval [CI], 1.4 to 1.6 months; range, < 1 month to 24 months). Independent predictors of receipt of an OAB medication included increasing age (odds ratio [OR], 1.4 for every 10 years; 95% CI, 1.4 to 1.5), women (OR, 1.6 compared with men; 95% CI, 1.4 to 1.8), diabetes (OR, 1.3; 95% CI, 1.1 to 1.5), and certain sources of care compared with PCP-only care: PCP/specialty co-management (OR, 1.8; 95% CI, 1.5 to 2.0), urology (OR, 2.2; 95% CI, 1.8 to 2.6), and multiple specialists (OR, 1.4; 95% CI, 1.2 to 1.8). Very few patients received other treatments: biofeedback (< 1%), onabotulinumtoxinA (2%), or sacral nerve stimulation (1%). Patients who received OAB medications had significantly higher anticholinergic burden than patients who did not (anticholinergic total standardized daily dose, 125 versus 46; P < .001). CONCLUSIONS: Although OAB is common and morbid, in a longitudinal study using an EHR OAB phenotype 40% of patients were treated with OAB medication and only briefly.

Patient-centered care innovations by accountable care organizations: Lessons from leaders.

Although there is a widespread belief that ACOs must be patient-centered to be successful, evidence to guide them in achieving that goal has been lacking. This case report examines four ACO innovators in patient-centered care that together represent urban, suburban and rural populations with a broad range of economic, racial, ethnic and geographic diversity. Seven patient-centeredness strategies emerged: transform primary care practices into patient-centered medical homes; move upstream to address social and economic issues; use both high-tech and high-touch to identify and engage high-risk patients; practice a whole-person orientation; optimize patient-reported measures; treat patients like valued customers; and incorporate patient voices into governance and operations. Exemplars prioritized direct care interventions perceived as central to financial and clinical success, and organizational maturity played a role. Activities that decreased the traditional system's authority, such as incorporating patient voices, were less popular. Local practice factors were important, and a mixture of mission and margin energized front-line staff in implementing patient-centered care as "the right thing to do." Unresolved questions remain that are related to the impact of individual and multiple interventions and how successful interventions can be disseminated widely. In order for patient-centeredness innovations to enable transformation, providers, payers and policymakers alike must consciously adopt strategies that nurture it.

Patient Presentations in Outpatient Settings: Epidemiology of Adult Head Trauma Treated Outside of Hospital Emergency Departments.

BACKGROUND: While deaths, hospitalizations, and emergency department visits for head trauma are well understood, little is known about presentations in outpatient settings. Our objective was to examine the epidemiology and extent of healthcare-seeking adult (18-64 years) head trauma patients presenting in outpatient settings compared with patients receiving nonhospitalized emergency department care. METHODS: We used 2004-2013 MarketScan Medicaid/commercial claims to identify head trauma patients managed in outpatient settings (primary care provider, urgent care) and the emergency department. We examined differences in demographic and injury-specific factors, Centers for Disease Control and Prevention-defined head trauma diagnoses, and extent of and reasons for postindex visit ambulatory care use within 30/90/180 days by index visit location, as well as annual and monthly variations in head trauma trends. We used outpatient incidence rates to estimate the US nationwide outpatient burden. RESULTS: A total of 1.19 million index outpatient visits were included (emergency department: 348,659). Nationwide, they represented a weighted annual burden of 1.16 million index outpatient cases. These encompassed 46% of all known healthcare-seeking head trauma in 2013 (outpatient/emergency department/inpatient/fatalities) and increased in magnitude (+31%) from 2004 to 2013. One fourth (27%) of office/clinic visits led to diagnosis with concussion on index presentation (urgent care: 32%). Distributions of demographic factors varied with index visit location while injury-specific factors were largely comparable. Subsequent visits reflected high demand for follow-up treatment, increased concussive diagnoses, and sequelae-associated care. CONCLUSIONS: Adult outpatient presentations of head trauma remain poorly understood. The results of this study demonstrate the extensive magnitude of their occurrence and close association with need for follow-up care.

Reduction of Blood Loss by Tranexamic Acid Following Total Hip and Knee Arthroplasty: A Meta-Analysis.

BACKGROUND: This study involved a meta-analysis of 36 published studies to examine the efficacy of intravenous (IV) and intra-articular (IA) tranexamic acid (TXA) in reducing blood loss, drain output, thromboembolic complications, and hospital stay following total hip and total knee arthroplasty. This study also evaluated whether treatment with a combination of both IA and IV TXA has an effect on these outcomes. Lastly, this study attempted to analyze the method and technique of TXA administration in order to establish a best practice for its use in reducing overall blood loss in arthroplasty procedures. METHODS: MEDLINE, Embase, and the Cochrane Library database were screened. Studies comparing IV TXA with IA TXA or with combined IV and IA TXA were included. Data including total blood loss, drain output, thromboembolic complications, and hospital stay, where available, were analyzed using meta-analysis with fixed effects. Results are presented as the standardized mean difference (SMD), and meta-regression was employed to explore plausible demographic contributions to heterogeneity. RESULTS: Twenty-eight randomized controlled trials, 3 prospective cohort studies, and 5 retrospective cohort studies with 5,499 patients were included in this review. IA administration during total knee arthroplasty showed a significant advantage in terms of total blood loss (SMD = -0.14, 95% confidence interval [CI] = -0.027 to -0.02, I = 78.2%) and drain output (SMD = -0.30, 95% CI = -0.43 to -0.18). There was no significant difference between IV and IA administration in total hip arthroplasty. Combined IA plus IV TXA was associated with a significant reduction in blood loss versus IV TXA alone in both total knee arthroplasty and total hip arthroplasty. IV TXA dosing varied, as 14 (39%) of the studies used a weight-based approach while 22 (61%) used a standard dose. Twenty-seven (96%) of 28 studies of IA administration used standard dosing while 1 study followed a weight-based protocol. There was no difference in symptomatic thromboembolic complications, with overall rates in total knee arthroplasty and total hip arthroplasty of 1.0% and 1.0% for IV administration and 1.1% and 0.3% for IA administration, respectively. There was no difference in length of hospital stay for IV versus IA TXA administration. CONCLUSIONS: IA TXA, either alone or in conjunction with IV TXA, reduces total blood loss and/or drain output in total knee arthroplasty and total hip arthroplasty. Optimal methodology remains to be clarified; however, there are substantial economic benefits of utilizing either IV or IA TXA, with greater cost benefits when using IA TXA. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Conscious status is associated with the likelihood of trauma centre care and mortality in patients with moderate-to-severe traumatic brain injury.

OBJECTIVE: To assess the relationship between The International Classification of Diseases, Ninth Revision, Clinical Modification-derived conscious status and mortality rates in trauma centres (TC) vs. non-trauma centres (NTC). METHODS: Patients in the 2006-2011 Nationwide Emergency Department Sample meeting, The Centers for Disease Control and Prevention criteria for traumatic brain injury (TBI), with head/neck Abbreviated Injury Scale (AIS) scores ≥3 were included. Loss of consciousness (LOC) was computed for each patient. Primary outcomes included treatment at a level I/II TC vs. NTC and in-hospital mortality. We compared logistic regression models controlling for patient demographics, injury characteristics, and AIS score with identical models that also included LOC. RESULTS: Of 66,636 patients with isolated TBI identified, 15,761 (23.6%) had missing LOC status. Among the remaining 50,875 patients, 59.0% were male, 54.0% were ≥65 years old, 56.7% were treated in TCs, and 27.3% had extended LOC. Patients with extended LOC were more likely to be treated in TCs vs. those with no/brief LOC (71.1% vs. 51.4%, p < 0.001). Among patients aged <65, TC treatment was associated with increased odds of mortality [Adjusted Odds Ratio (AOR) 1.79]; accounting for LOC substantially mitigated this relationship [AOR 1.27]. Similar findings were observed among older patients, with reduced effect size. CONCLUSION: Extended LOC was associated with TC treatment and mortality. Accounting for patient LOC reduced the differential odds of mortality comparing TCs vs. NTCs by 60%. Research assessing TBI outcomes using administrative data should include measures of consciousness.

The Epidemiology of Pediatric Head Injury Treated Outside of Hospital Emergency Departments.

BACKGROUND: Although head trauma-related deaths, hospitalizations, and emergency department visits are well characterized, few studies describe pediatric patients presenting outside of emergency departments. We compared the epidemiology and extent of healthcare-seeking pediatric (0-17 years) patients presenting in outpatient settings with those of patients seeking nonhospitalized emergency department care. METHODS: We used MarketScan Medicaid and commercial claims, 2004-2013, to identify patients managed in two outpatient settings (physician's offices/clinics, urgent care) and the emergency department. We then examined differences in demographic and injury-specific factors, Centers for Disease Control and Prevention-defined head trauma diagnoses, the extent of and reasons for post-index visit ambulatory care use within 30/90/180 days, and annual and monthly variations in head trauma trends. Outpatient incidence rates in 2013 provided estimates of the nationwide US outpatient burden. RESULTS: A total of 1,683,097 index visits were included, representing a nationwide burden in 2013 of 844,660 outpatient cases, a number that encompassed 51% of healthcare-seeking head trauma that year and that substantially increased in magnitude from 2004 to 2013. Two-thirds (68%) were managed in outpatient settings. While demographic distributions varied with index-visit location, injury-specific factors were comparable. Seasonal spikes appeared to coincide with school sports. CONCLUSIONS: There is an urgent need to better understand the natural history of head trauma in the >800,000 pediatric patients presenting each year for outpatient care. These outpatient injuries, which are more than double the number of head trauma cases recorded in the hospital-affiliated settings, illustrate the potential importance of expanding inclusion criteria in surveillance and prevention efforts designed to address this critical issue.

Occupational Variation in End-of-Life Care Intensity.

BACKGROUND: End-of-life (EOL) care intensity is known to vary by secular and geographic patterns. US physicians receive less aggressive EOL care than the general population, presumably the result of preferences shaped by work-place experience with EOL care. OBJECTIVE: We investigated occupation as a source of variation in EOL care intensity. METHODS: Across 4 states, we identified 660 599, nonhealth maintenance organization Medicare beneficiaries aged ≥66 years who died between 2004 and 2011. Linking death certificates, we identified beneficiaries with prespecified occupations: nurses, farmers, clergy, mortuary workers, homemakers, first-responders, veterinary workers, teachers, accountants, and the general population. End-of-life care intensity over the last 6 months of life was assessed using 5 validated measures: (1) Medicare expenditures, rates of (2) hospice, (3) surgery, (4) intensive care, and (5) in-hospital death. RESULTS: Occupation was a source of large variation in EOL care intensity across all measures, before and after adjustment for sex, education, age-adjusted Charlson Comorbidity Index, race/ethnicity, and hospital referral region. For example, absolute and relative adjusted differences in expenditures were US$9991 and 42% of population mean expenditure ( P < .001 for both). Compared to the general population on the 5 EOL care intensity measures, teachers (5 of 5), homemakers (4 of 5), farmers (4 of 5), and clergy (3 of 5) demonstrated significantly less aggressive care. Mortuary workers had lower EOL care intensity (4 of 5) but small numbers limited statistical significance. CONCLUSION: Occupations with likely exposure to child development, death/bereavement, and naturalistic influences demonstrated lower EOL care intensity. These findings may inform patients and clinicians navigating choices around individual EOL care preferences.
