Effectiveness of Existing Insomnia Therapies for Patients Undergoing Hemodialysis : A Randomized Clinical Trial.

BACKGROUND: Chronic insomnia is common in patients undergoing in-center hemodialysis, yet there is limited evidence on effective treatments for this population. OBJECTIVE: To compare the effectiveness of cognitive behavioral therapy for insomnia (CBT-I), trazodone, and placebo for insomnia in patients undergoing long-term hemodialysis. DESIGN: Randomized, multicenter, double-blinded, placebo-controlled trial. (ClinicalTrials.gov: NCT03534284). SETTING: 26 dialysis units in Albuquerque, New Mexico, and Seattle, Washington. PARTICIPANTS: Patients with Insomnia Severity Index (ISI) score of 10 or greater, with sleep disturbances on 3 or more nights per week for 3 or more months. INTERVENTION: Participants were randomly assigned to 6 weeks of CBT-I, trazodone, or placebo. MEASUREMENTS: The primary outcome was the ISI score at 7 and 25 weeks from randomization. RESULTS: A total of 923 patients were prescreened, and of the 411 patients with chronic insomnia, 126 were randomly assigned to CBT-I (n = 43), trazodone (n = 42), or placebo (n = 41). The change in ISI scores from baseline to 7 weeks with CBT-I or trazodone was no different from placebo: CBT-I, -3.7 (95% CI, -5.5 to -1.9); trazodone, -4.2 (CI, -5.9 to -2.4); and placebo, -3.1 (CI, -4.9 to -1.3). There was no meaningful change in ISI scores from baseline to 25 weeks: CBT-I, -4.8 (CI, -7.0 to -2.7); trazodone, -4.0 (CI, -6.0 to -1.9); and placebo, -4.3 (CI, -6.4 to -2.2). Serious adverse events (SAEs), particularly serious cardiovascular events, were more frequent with trazodone (annualized cardiovascular SAE incidence rates: CBT-I, 0.05 [CI, 0.00 to 0.29]; trazodone, 0.64 [CI, 0.34 to 1.10]; and placebo, 0.21 [CI, 0.06 to 0.53]). LIMITATION: Modest sample size and most participants had mild or moderate insomnia. CONCLUSION: In patients undergoing hemodialysis with mild or moderate chronic insomnia, there was no difference in the effectiveness of 6 weeks of CBT-I or trazodone compared with placebo. The incidence of SAEs was higher with trazodone. PRIMARY FUNDING SOURCE: National Institutes of Health/National Institute of Diabetes and Digestive and Kidney Diseases.

Sleep-HD trial: short and long-term effectiveness of existing insomnia therapies for patients undergoing hemodialysis.

BACKGROUND: Patients with end-stage kidney disease (ESKD) treated with hemodialysis (HD) experience many distressing symptoms. One frequently reported symptom is insomnia. There are unique issues about HD treatments and schedules that disrupt regular sleep/wake routines and possibly contribute to the high severity of insomnia. Despite evidence for broad-ranging health effects of insomnia, very few clinical trials have tested the efficacy of treatments for HD patients. Cognitive-behavioral therapy for insomnia (CBT-I) is a recommended first-line therapy but largely inaccessible to HD patients in the United States, partly because they commit considerable amounts of time to thrice-weekly dialysis treatments. Another important reason could be the logistical and reimbursement challenges associated with providing behavioral health care at the dialysis center. CBT-I delivered by telehealth can overcome barriers to access, but its efficacy has never been rigorously tested for these patients. Pharmacotherapy is the most widely used treatment for insomnia; however, some drugs presently used are unsafe as they are associated with a higher risk for death for HD patients (benzodiazepines and zolpidem-like drugs). The efficacy and safety of other medications (trazodone) for the treatment of insomnia has never been tested for patients treated with HD. METHODS: This trial tests the short- and long-term comparative effectiveness of 6-week treatment with telehealth CBT-I, trazodone, or medication placebo. This will be accomplished with a randomized controlled trial (RCT) in which 126 participants treated with HD in community-based dialysis facilities with chronic insomnia will be assigned 1:1:1 to telehealth CBT-I, trazodone, or medication placebo, respectively; short-term effectiveness of each treatment arm will be determined at the end of 6-weeks of treatment and long-term effectiveness at 25-weeks. The primary and secondary patient-reported outcomes will be assessed with computer-based telephone interviewing by research scientists blinded to treatment assignment; additional secondary outcomes will be assessed by participant interview and actigraphy. DISCUSSION: This clinical RCT will provide the first evidence for the comparative effectiveness of two distinct approaches for treating chronic insomnia and other patient-reported outcomes for patients receiving maintenance HD.

Telementoring for improving primary care provider knowledge and competence in managing chronic pain: A randomised controlled trial.

Introduction: Primary care providers are frequently unprepared to manage chronic pain adequately due in part to insufficient professional training. This study evaluated the effect of a telementoring intervention on knowledge and perceived competence related to chronic pain management. Methods: The study design was a cluster randomised controlled trial. Primary care clinics that were part of the University of Washington Medicine Telehealth network were the unit of randomization. Primary care providers comprised the intervention group (n = 23) and the control group (n = 18). Providers in the intervention group attended telementoring sessions through the TelePain programme and presented patient cases at the beginning and end of their enrolled patients' 12-week study period. TelePain sessions included a didactic presentation and telementoring for specific patient cases by a panel of pain specialists from the disciplines of pain medicine, internal medicine, anaesthesiology, rehabilitation medicine, psychiatry, addiction medicine, nursing and complementary and integrative pain management. Providers' baseline and end-of-study knowledge and perceived competence in managing chronic pain were assessed by three questionnaires: Knowledge and Attitudes Survey Regarding Pain, the KnowPain-12 and the Perceived Competence Scale. Results: Knowledge (Z = ­0.34, p = 0.97 (Knowledge and Attitudes Survey Regarding Pain) and Z = 0.49, p = 0.62 (KnowPain-12)) and perceived competence (Z = ­0.74, p = 0.46) did not increase for providers in the intervention group compared with providers in the control group. These providers attended on average 12.5 sessions (range 0­31) while participating in the study. Discussion: Further research is recommended to establish the effectiveness of this telementoring intervention.

Contractile forces in platelet aggregates under microfluidic shear gradients reflect platelet inhibition and bleeding risk.

Platelets contract forcefully after their activation, contributing to the strength and stability of platelet aggregates and fibrin clots during blood coagulation. Viscoelastic approaches can be used to assess platelet-induced clot strengthening, but they require thrombin and fibrin generation and are unable to measure platelet forces directly. Here, we report a rapid, microfluidic approach for measuring the contractile force of platelet aggregates for the detection of platelet dysfunction. We find that platelet forces are significantly reduced when blood samples are treated with inhibitors of myosin, GPIb-IX-V, integrin αIIbß3, P2Y12, or thromboxane generation. Clinically, we find that platelet forces are measurably lower in cardiology patients taking aspirin. We also find that measuring platelet forces can identify Emergency Department trauma patients who subsequently require blood transfusions. Together, these findings indicate that microfluidic quantification of platelet forces may be a rapid and useful approach for monitoring both antiplatelet therapy and traumatic bleeding risk.

Comparative Efficacy of Therapies for Treatment of Depression for Patients Undergoing Maintenance Hemodialysis: A Randomized Clinical Trial.

Background: Although depression is common among patients receiving maintenance hemodialysis, data on their acceptance of treatment and on the comparative efficacy of various therapies are limited. Objective: To determine the effect of an engagement interview on treatment acceptance (phase 1) and to compare the efficacy of cognitive behavioral therapy (CBT) versus sertraline (phase 2) for treating depression in patients receiving hemodialysis. Design: Multicenter, parallel-group, open-label, randomized controlled trial. (ClinicalTrials.gov: NCT02358343). Setting: 41 dialysis facilities in 3 U.S. metropolitan areas. Participants: Patients who had been receiving hemodialysis for at least 3 months and had a Beck Depression Inventory-II score of 15 or greater; 184 patients participated in phase 1, and 120 subsequently participated in phase 2. Intervention: Engagement interview versus control visit (phase 1) and 12 weeks of CBT delivered in the dialysis facility versus sertraline treatment (phase 2). Measurements: The primary outcome for phase 1 was the proportion of participants who started depression treatment within 28 days. For phase 2, the primary outcome was depressive symptoms measured by the Quick Inventory of Depressive Symptoms-Clinician-Rated (QIDS-C) at 12 weeks. Results: The proportion of participants who initiated treatment after the engagement or control visit did not differ (66% vs. 64%, respectively; P = 0.77; estimated risk difference, 2.1 [95% CI, -12.1 to 16.4]). Compared with CBT, sertraline treatment resulted in lower QIDS-C depression scores at 12 weeks (effect estimate, -1.84 [CI, -3.54 to -0.13]; P = 0.035). Adverse events were more frequent in the sertraline than the CBT group. Limitation: No randomized comparison was made with no treatment, and persistence of treatment effect was not assessed. Conclusion: An engagement interview with patients receiving maintenance hemodialysis had no effect on their acceptance of treatment for depression. After 12 weeks of treatment, depression scores were modestly better with sertraline treatment than with CBT.

Risk interval analysis of emergency room visits following colonoscopy in patients with inflammatory bowel disease.

BACKGROUND AND AIMS: Prior studies suggest that colonoscopy may exacerbate inflammatory bowel disease (IBD) symptoms. Thus, our study aimed to determine risk of emergency room (ER) visits associated with colonoscopy among IBD patients and evaluate potential modifiers of this risk. METHODS: The study population included IBD patients in the Multi-Payer Claims Database who were >20 years old and had a colonoscopy from 2007-2010. We used a self-controlled risk interval design and mixed-effects Poisson regression models to calculate risk ratios (RR) and 95% confidence intervals (CI) comparing the incidence of ER visits in the 1-4 weeks following colonoscopy (risk interval) to the incidence of ER visits in the 7-10 weeks after colonoscopy (control interval). We also conducted stratified analyses by patient characteristics, bowel preparation type, and medication. RESULTS: There were 212,205 IBD patients with at least 1 colonoscopy from 2007-2010, and 3,699 had an ER visit during the risk and/or control interval. The risk of an ER visit was higher in the 4-week risk interval following colonoscopy compared to the control interval (RR = 1.24; 95% CI: 1.17-1.32). The effect was strongest in those <41 years old (RR = 1.60; 95% CI: 1.21-2.11), in women (RR = 1.32; 95% CI: 1.21-1.44), and in those with sodium phosphate bowel preparation (RR = 2.09; 95% CI: 1.02-4.29). Patients using immunomodulators had no increased risk of ER visits (RR = 0.75; 95% CI: 0.35-1.59). CONCLUSIONS: Our results suggest that there is an increased risk of ER visits following colonoscopy among IBD patients, but that immunomodulators and mild bowel preparation agents may mitigate this risk.

Acceptability of mHealth augmentation of Collaborative Care: A mixed methods pilot study.

OBJECTIVE: To assess the feasibility and acceptability of a mobile health platform supporting Collaborative Care. METHOD: Collaborative Care patients (n=17) used a smartphone app to transmit PHQ-9 and GAD-7 scores and sensor data to a dashboard used by one care manager. Patients completed usability and satisfaction surveys and qualitative interviews at 4weeks and the care manager completed a qualitative interview. Mobile metadata on app usage was obtained. RESULTS: All patients used the app for 4weeks, but only 35% (n=6) sustained use at 8weeks. Prior to discontinuing use, 88% (n=15) completed all PHQ-9 and GAD-7 measures, with lower response rates for daily measures. Four themes emerged from interviews: understanding the purpose; care manager's role in supporting use; benefits of daily monitoring; and privacy / security concerns. Two themes were user-specific: patients' desire for personalization; and care manager burden. CONCLUSIONS: The feasibility and acceptability of the mobile platform is supported by the high early response rate, however attrition was steep. Our qualitative findings revealed nuanced participant experiences and uncovered some concerns about mobile health. To encourage retention, attention may need to be directed toward promoting patient understanding and provider engagement, and offering personalized patient experiences.

Racial Disparities in Outpatient Mental Health Service Use Among Children Hospitalized for Traumatic Brain Injury.

OBJECTIVE: To examine racial differences in mental health service utilization after hospitalization for traumatic brain injury (TBI) among children with Medicaid insurance. DESIGN AND MAIN MEASURES: Retrospective analysis of the MarketScan Multi-State Medicaid database from 2007 to 2012 was performed. Outpatient mental health service utilization (psychiatric and psychological individual and group services) was compared at TBI hospitalization, from discharge to 3 months and from 4 to 12 months after discharge, between children of non-Hispanic white (NHW), non-Hispanic black (NHB), Hispanic, and "Other" racial groups. Multivariable mixed-effects Poisson regression models with robust standard errors were utilized. RESULTS: A total of 5674 children (aged <21 years) were included in the study. There were no differences by race/ethnicity in mental health service utilization during hospitalization. At 3 months postdischarge, NHB children and children in the "Other" racial category were significantly less likely to receive outpatient mental health services than NHW children (NHB relative risk [RR] = 0.84; 95% confidence interval [CI], 0.72-0.98; Other RR = 0.72; 95% CI, 0.57-0.90). At 12 months, all racial minority children were significantly less likely to receive outpatient mental health services than NHW children (NHB RR = 0.84; 95% CI, 0.75-0.94; Hispanic RR = 0.72; 95% CI, 0.55-0.94; Other RR = 0.71; 95% CI, 0.60-0.84). CONCLUSIONS: Racial disparities in utilization of outpatient mental health services exist for minority children hospitalized for TBI and insured by Medicaid. Future research should focus on improving transitions of care from inpatient to outpatient services for these children.

Use of Self-management Interventions for Chronic Pain Management: A Comparison between Rural and Nonrural Residents.

Individuals with chronic pain who live in rural communities often lack access to pain specialists and rely on primary care providers who may be less prepared. Research has indicated that rural residents with chronic pain are more likely to receive an opioid prescription than nonrural residents. Although self-management approaches are available for chronic pain management, it is unclear to what extent rural residents use these interventions. This study compares usage of self-management interventions and opioid-based analgesics for chronic pain management between rural and nonrural residents. This study is a secondary analysis of baseline data from a randomized controlled trial evaluating a telehealth intervention for chronic pain management. Participants, recruited from primary care clinics, were 65 rural residents and 144 nonrural residents with similar demographic characteristics. Differences in the use of self-management interventions, pain intensity, and opioid dose were evaluated between rural and nonrural residents. Rural residents (n = 50, 77%) were less likely to use self-management interventions compared with nonrural residents (n = 133, 92%) (p = .019). Opioids were taken for pain relief by 76% of the rural residents compared with 52% of the nonrural residents. A disparity exists in the use of self-management interventions for chronic pain management by rural residents compared with nonrural residents. Further study is needed to determine if this is related to the lack of access to specialists and/or pain management training of primary care providers. Nurses can play an essential role in addressing this disparity by educating patients about self-management interventions.

Patient-oriented health technologies: Patients' perspectives and use.

BACKGROUND: For patient-oriented mobile health tools to contribute meaningfully to improving healthcare delivery, widespread acceptance and use of such tools by patients are critical. However, little is known about patients' attitudes toward using health technology and their willingness to share health data with providers. AIMS: To investigate primary care patients' comfort sharing health information through mobile devices, and patients' awareness and use of patient portals. METHODS: Patients (n=918) who visited one of 6 primary care clinics in the Northwest US completed a survey about health technology use, medical conditions, and demographics. RESULTS: More patients were comfortable sharing mobile health information with providers than having third parties store their information (62% vs 30%, Somers D=.33, p<0.001). Patients older than 55 years were less likely to be comfortable sharing with providers (AORs 0.37-0.42, p<0.01). Only 39% of patients knew if their clinic offered a patient portal; however, of these, 67% used it. Health literacy limitations were associated with lower portal awareness (AOR=0.55, p=0.005) but not use. Portal use was higher among patients with a chronic condition (AOR= 3.18, p=0.004). CONCLUSION: Comfort, awareness, and use of health technologies were variable. Practices introducing patient-facing health technologies should promote awareness, address concerns about data security, and provide education and training, especially to older adults and those with health literacy limitations. Patient-facing health technologies provide an opportunity for delivering scalable health education and self-management support, particularly for patients with chronic conditions who are already using patient portals.

TelePain: Primary Care Chronic Pain Management through Weekly Didactic and Case-based Telementoring.

Chronic pain is a significant problem among military personnel and a priority of the military health system. The U.S. Army Surgeon General's Pain Management Task Force recommends using telehealth capabilities to enhance pain management. This article describes the development and evaluation of a telehealth intervention (TelePain) designed to improve access to pain specialist consultation in the military health system. The study uses a wait-list controlled clinical trial to test: 1) effectiveness of the intervention, and 2) interviews to assess barriers and facilitators of the intervention implementation. The intervention involves a didactic presentation based on the Joint Pain Education Curriculum followed by patient case presentations and multi-disciplinary discussion via videoconference by clinicians working in the military health system. A panel of pain specialists representing pain medicine, internal medicine, anesthesiology, rehabilitation medicine, psychiatry, addiction medicine, health psychology, pharmacology, nursing, and complementary and integrative pain management provide pain management recommendations for each patient case. We use the Pain Assessment Screening Tool and Outcomes Registry (PASTOR) to measure patient outcomes, including pain, sleep, fatigue, anxiety, and depression. This article reports some of the challenges and lessons learned during early implementation of the TelePain intervention. Weekly telephone meetings among the multisite research team were instrumental in problem solving, identifying problem areas, and developing solutions. Solutions for recruitment challenges included additional outreach and networking to military health providers, both building on.

The Family Communication Study: A randomized trial of prospective pediatric palliative care consultation, study methodology and perceptions of participation burden.

BACKGROUND: To describe the study methods, baseline characteristics and burden of study procedures of an intervention designed to reduce family stress symptoms through early support from the palliative care team. Length of stay of ≥8days was the trigger for early palliative care involvement. METHODS: Cluster-randomized trial with children as the unit of randomization. Up to 3 family members per child were recruited. Family stress symptoms were recorded at baseline, discharge from the ICU, and 3months post-enrollment. Questionnaire burden was assessed on a 1-10 point scale at each time point and open-ended comments were analyzed to describe the participants' experience in the study. RESULTS: 380 family members of 220 children (control=115 children and 204 family members; intervention=105 children and 176 family members) were recruited, which represented 50% of all eligible families. Most family participants were parents (86% control; 92% intervention) and female (66% both groups). Retention rates were high through the 3-month follow-up: 93% and 90% for the control and intervention groups respectively. Questionnaire burden was very low: mean (sd) scores were 1.1 (1.6), 0.7 (1.5), and 0.9 (1.6) for the baseline, discharge and follow-up questionnaires, respectively. Comments suggest that participation was beneficial by promoting reflection and self-awareness about stress, coping and resilience, and feeling cared for because the intervention and questionnaires focused on their own well-being. CONCLUSIONS: The participants' comments regarding the focus on them as the point of intervention reflects the value of conducting research with family members of seriously ill children during ICU stays.

Feeding Neonates by Cup: A Systematic Review of the Literature.

Objective WHO and UNICEF recommend cup feeding for neonates unable to breastfeed in low-resource settings. In developed countries, cup feeding in lieu of bottle feeding in the neonatal period is hypothesized to improve breastfeeding outcomes for those initially unable to breastfeed. Our aim was to synthesize the entire body of evidence on cup feeding. Methods We searched domestic and international databases for original research. Our search criteria required original data on cup feeding in neonates published in English between January 1990 and December 2014. Results We identified 28 original research papers. Ten were randomized clinical trials, 7 non-randomized intervention studies, and 11 observational studies; 11 were conducted in developing country. Outcomes evaluated included physiologic stability, safety, intake, duration, spillage, weight gain, any and exclusive breastfeeding, length of hospital stay, compliance, and acceptability. Cup feeding appears to be safe though intake may be less and spillage greater relative to bottle or tube feeding. Overall, slightly higher proportions of cup fed versus bottle fed infants report any breastfeeding; a greater proportion of cup fed infants reported exclusive breastfeeding at discharge and beyond. Cup feeding increases breastfeeding in subgroups (e.g. those who intend to breastfeed or women who had a Caesarean section). Compliance and acceptability is problematic in certain settings. Conclusions Further research on long-term breastfeeding outcomes and in low-resource settings would be helpful. Research data on high risk infants (e.g. those with cleft palates) would be informative. Innovative cup feeding approaches to minimize spillage, optimize compliance, and increase breastfeeding feeding are needed.

Rationale and design of A Trial of Sertraline vs. Cognitive Behavioral Therapy for End-stage Renal Disease Patients with Depression (ASCEND).

Major Depressive Disorder (MDD) is highly prevalent in patients with End Stage Renal Disease (ESRD) treated with maintenance hemodialysis (HD). Despite the high prevalence and robust data demonstrating an independent association between depression and poor clinical and patient-reported outcomes, MDD is under-treated when identified in such patients. This may in part be due to the paucity of evidence confirming the safety and efficacy of treatments for depression in this population. It is also unclear whether HD patients are interested in receiving treatment for depression. ASCEND (Clinical Trials Identifier Number NCT02358343), A Trial of Sertraline vs. Cognitive Behavioral Therapy (CBT) for End-stage Renal Disease Patients with Depression, was designed as a multi-center, 12-week, open-label, randomized, controlled trial of prevalent HD patients with comorbid MDD or dysthymia. It will compare (1) a single Engagement Interview vs. a control visit for the probability of initiating treatment for comorbid depression in up to 400 patients; and (2) individual chair-side CBT vs. flexible-dose treatment with a selective serotonin reuptake inhibitor, sertraline, for improvement of depressive symptoms in 180 of the up to 400 patients. The evolution of depressive symptoms will also be examined in a prospective longitudinal cohort of 90 HD patients who choose not to be treated for depression. We discuss the rationale and design of ASCEND, the first large-scale randomized controlled trial evaluating efficacy of non-pharmacologic vs. pharmacologic treatment of depression in HD patients for patient-centered outcomes.

Two Hundred Thirty-Six Children With Developmental Hydrocephalus: Causes and Clinical Consequences.

Few systematic assessments of developmental forms of hydrocephalus exist. We reviewed magnetic resonance images (MRIs) and clinical records of patients with infancy-onset hydrocephalus. Among 411 infants, 236 had hydrocephalus with no recognizable extrinsic cause. These children were assigned to 1 of 5 subtypes and compared on the basis of clinical characteristics and developmental and surgical outcomes. At an average age of 5.3 years, 72% of children were walking independently and 87% could eat by mouth; in addition, 18% had epilepsy. Distinct patterns of associated malformations and syndromes were observed within each subtype. On average, children with aqueductal obstruction, cysts, and encephaloceles had worse clinical outcomes than those with other forms of developmental hydrocephalus. Overall, 53% of surgically treated patients experienced at least 1 shunt failure, but hydrocephalus associated with posterior fossa crowding required fewer shunt revisions. We conclude that each subtype of developmental hydrocephalus is associated with distinct clinical characteristics, syndromology, and outcomes, suggesting differences in underlying mechanisms.

"Polio Eradication" Game May Increase Public Interest in Global Health.

BACKGROUND: Interactive games that highlight global health challenges and solutions are a potential tool for increasing interest in global health. To test this hypothesis, we developed an interactive "Polio Eradication" (PE) game and evaluated whether playing or watching was associated with increased public interest in global health. MATERIALS AND METHODS: The PE game is a life-size, human board game that simulates PE efforts. Four players-a researcher, a transportation expert, a local community coordinator, and a healthcare worker-collaborate as an interdisciplinary team to help limit ongoing and future polio outbreaks in Pakistan, represented on the game board. Participants who played or observed the game and those who did not participate in the game, but visited noninteractive global health exhibits, completed a survey on participation outcomes. We used relative risk regression to examine associations between cofactors and change in global health interest. RESULTS: Three variables predicted increased global health interest among the game participants: Having little or no previous global health knowledge prior to playing the game (risk ratio [RR]=1.28; 95 percent confidence interval [CI], 1.13-1.45), not currently being involved in global health (RR=1.41; 95 percent CI, 1.07-1.85), and visiting Seattle (RR=1.25; 95 percent CI, 1.04-1.51). CONCLUSIONS: Our results suggest that a hands-on, interactive game may increase the public's interest in global health, particularly among those with minimal previous knowledge of or involvement in global health activities.

Visits to US emergency departments by 20- to 29-year-olds with toothache during 2001-2010.

BACKGROUND: Visits to emergency departments (EDs) for dental symptoms are on the rise, yet reliance on EDs for dental care is far from ideal. ED toothache visits represent opportunities to improve access to professional dental care. METHODS: This research focuses on 20- to 29-year-olds, who account for more ED toothache visits than do other age groups. The authors analyzed publicly available ED visit data from the National Hospital Ambulatory Medical Care Survey (NHAMCS) from 2001 through 2010. They assessed trends in ED toothache visit rates compared with back pain and all cause ED visits during the past decade. The authors used NHAMCS data for years 2009 and 2010 to characterize the more recent magnitude, relative frequency, and independent risk factors for ED toothache visits. Statistical analyses accounted for the complex sampling design. RESULTS: The average annual increase in ED visit rates among 20- to 29-year-olds during 2001-2010 was 6.1% for toothache, 0.3% for back pain, and 0.8% for all causes of ED visits. In 2009 and 2010, 20- to 29-year-olds made an estimated 1.27 million ED visits for toothaches and accounted for 42% of all ED toothache visits. Toothache was the fifth most common reason for any ED visit and third most common for uninsured ED visits by 20- to 29-year-olds. Independent risk factors for ED toothache visits were being uninsured or Medicaid-insured. CONCLUSIONS: Younger adults increasingly rely on EDs for toothaches-likely because of barriers to accessing professional dental care. Expanding dental coverage and access to affordable dental care could increase options for timely dental care and decrease ED use for dental symptoms. PRACTICAL IMPLICATIONS: Though additional research is needed to better understand why younger adults disproportionately use the ED for toothaches, findings from this study suggest the importance of maintaining access to a dental home from childhood through adolescence and subsequently into early adulthood.
