RESUMEN
OBJECTIVE: Although 72-hour return visits are a frequently reported metric for pediatric patients discharged from the emergency department (ED), the basis for this metric is not established. Our objective was to statistically derive a cutoff time point for the characterization of pediatric return visits. METHODS: We performed a retrospective cohort study using data of patients discharged from any of 44 pediatric EDs. We selected the first encounter per patient from January 1 to December 31, 2019, as the index encounter and included the first return visit within 30 days. We constructed a cumulative hazard curve to characterize the timing of return visits and constructed a multivariable adaptive regression spline model to identify a hinge point in return visit presentations. We identified the association between admission for early return visits and admission for late return visits using generalized linear mixed modeling. RESULTS: Of 1,986,778 index ED discharges, 193,605 (9.7%) ED return visits were included. A double-exponential decay model demonstrated superior fit compared with a single exponential model ( P < 0.0001). Multivariable adaptive regression spline modeling identified a hinge at 7 days. When comparing proportions of return visits leading to hospitalization between early (23.8%) and late (15.1%) return visits, early visits (≤7 days) had higher adjusted odds of hospital admission (adjusted odds ratio, 1.73; 95% confidence interval, 1.69-1.77) relative to late return visits (>7 days). Findings were similar in sensitivity analyses within age subgroups, Census region, and in which the diagnosis (using the Diagnosis and Grouping System) was the same between the index and return visit. Among return visits that occurred within 7 days of the index visit, 46.3% had the same diagnosis grouping in both visits. CONCLUSIONS: An empirically derived 7-day cutoff may be more appropriate for characterization of pediatric return visits to the ED. Encounters after this period had lower adjusted odds of admission.

OBJECTIVES: To determine how frequently patients revisit the emergency department after an initial encounter, and to describe revisit capture rates for the same hospital, health system, and geographic region. DATA SOURCES/STUDY SETTING: Florida state data from January 1, 2010, to June 30, 2011, from the Healthcare Cost and Utilization Project. STUDY DESIGN: This is a retrospective cohort study of emergency department return visits among Florida adults over an 18-month period. We evaluated pairs of index and 30-day return emergency department visits and compared capture rates for hospital, health system, and geographic units. DATA COLLECTION/EXTRACTION METHODS: Data were obtained from the Agency for Healthcare Research and Quality's Healthcare Cost and Utilization Project and the American Hospital Association Annual Survey Database. PRINCIPAL FINDINGS: Among 9,416,212 emergency department visits, 22.6 percent (2,124,441) were associated with a 30-day return. Seventy percent (1,477,772) of 30-day returns occurred to the same hospital. The 30-day return capture rates were highest within the same geographic area: county-level capture at 92 percent (IQR=86-96 percent) versus health system capture at 75 percent (IQR = 68-81 percent). CONCLUSIONS: Acute care utilization patterns are often independent of health system boundaries. Current population-based health care models that attribute patients to a single provider or health system may be strengthened by considering geographic patterns of acute care utilization.

OBJECTIVE: To estimate binge eating disorder (BED) prevalence according to DSM-5 and DSM-IV-TR criteria in US adults and to estimate the proportion of individuals meeting DSM-5 BED criteria who reported being formally diagnosed. METHODS: A representative sample of US adults who participated in the National Health and Wellness Survey were asked to respond to an Internet survey (conducted in October 2013). Assessments included 3-month, 12-month, and lifetime BED prevalence based on DSM-5 and DSM-IV-TR criteria and demographics, psychiatric comorbidities, and self-esteem (Rosenberg Self-Esteem Scale). Descriptive statistics are provided. Prevalence estimates were calculated using poststratification sampling weights. RESULTS: Of 22,397 respondents, 344 (women, n = 242; men, n = 102) self-reported symptoms consistent with DSM-5 BED symptom criteria. The 3-month, 12-month, and lifetime DSM-5 prevalence estimates (95% CIs) projected to the US population were 1.19% (1.04%-1.37%), 1.64% (1.45%-1.85%), and 2.03% (1.83%-2.26%), respectively. The 12-month and lifetime projected DSM-IV-TR prevalence estimates were 1.15% (1.00%-1.32%) and 1.52% (1.35%-1.70%), respectively. Of respondents meeting DSM-5 BED criteria in the past 12 months, 3.2% (11/344) reported receiving a formal diagnosis. Compared with non-BED respondents, respondents meeting DSM-5 BED criteria in the past 12 months were younger (mean ± SD age = 46.01 ± 14.32 vs 51.59 ± 15.80 years; P < .001), had a higher body mass index (mean ± SD = 33.71 ± 9.36 vs 27.96 ± 6.68 kg/m²; P < .001), and had lower self-esteem (mean ± SD score = 16.47 ± 6.99 vs 23.33 ± 6.06; P < .001). CONCLUSIONS: DSM-5 BED criteria resulted in higher BED prevalence estimates than with DSM-IV-TR criteria. Most BED respondents did not report being formally diagnosed, indicating an unmet need in BED recognition and diagnosis.

BACKGROUND: We previously reported results of the phase III, randomized, noninferiority trial comparing bendamustine-rituximab (BR) with standard R-CHOP (rituximab/cyclophosphamide/doxorubicin/vincristine/prednisone)/R-CVP (rituximab/cyclophosphamide/vincristine/prednisone) in previously untreated advanced indolent non-Hodgkin and mantle cell lymphomas. Here we report health-related quality of life (HRQOL) results from the trial. METHODS: HRQOL, as measured by the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30), was a secondary end point. Differences between group means in global health status (GHS), 5-item functioning, and 9 symptoms/single-item measures at week 1 of cycle 1 and end-of- cycles 3 and 6 were examined using the screening (baseline) score as a covariate in analysis of covariance. RESULTS: Overall EORTC QLQ-C30 compliance was 75.2%, 89.5%, and 89.9% at week 1 of cycle 1 and end-of-cycles 3 and 6, respectively. Patients treated with BR reported improvements in Cognitive Functioning, Physical Functioning, Social Functioning, Emotional Functioning, and GHS as well as reduction in dyspnea, constipation, and fatigue at some, but not all, time points. Patients treated with standard therapy reported less nausea/vomiting at one time point. CONCLUSION: Compared with patients treated with standard therapy, patients treated with BR reported better quality of life in several areas.

OBJECTIVES: Although 72-hour emergency department (ED) revisits are increasingly used as a hospital metric, there is no known empirical basis for this 72-hour threshold. The objective of this study was to determine the timing of ED revisits for adult patients within 30 days of ED discharge. METHODS: This was a retrospective cohort study of all nonfederal ED discharges in Florida and Nebraska from April 1, 2010, to March 31, 2011, using data from the Agency for Healthcare Research and Quality (AHRQ) Healthcare Cost and Utilization Project (HCUP). ED discharges were followed forward to identify ED revisits occurring at any hospital within the same state within 30 days. The cumulative hazard of an ED revisit was plotted. Parametric and nonparametric modeling was performed to characterize the rate of ED revisits. RESULTS: There were 4,782,045 ED discharges, with 7.5% (95% confidence interval [CI] = 7.4% to 7.5%) associated with 3-day revisits, and 22.4% (95% CI = 22.3% to 22.4%) associated with 30-day revisits, inclusive of the 3-day revisits. A double-exponential model fit the data best (p < 0.0001), and a single hinge point at 9 days (multivariate adaptive regression splines [MARS] model) yielded the best linear fit to the data, suggesting 9 days as the most reasonable cutoff for identification of acute ED revisits. Multiple stratified and subgroup analyses produced similar results. Future work should focus on identifying primary reasons for potentially avoidable return ED visits instead of on the revisit occurrence itself, thus more directly measuring potential lapses in delivery of high-quality care. CONCLUSIONS: Almost one-quarter of ED discharges are linked to 30-day ED revisits, and the current 72-hour ED metric misses close to 70% of these patients. Our findings support 9 days as a more inclusive cutoff for studies of ED revisits.

This study investigated predictors of pneumococcal polysaccharide vaccine (PPV) use among older adults in Brazil. Respondents aged ≥50 from 2011 National Health and Wellness Survey in Brazil who had ever (vs never) received PPV were compared on comorbid risk, sociodemographics and vaccination behaviors. Logistic regression and decision tree analyses predicted PPV receipt as a function of the measures. Among 3195 respondents, 8.7% reported ever receiving PPV (10.4% among those at risk). Adjusting for covariates, adults classified as high or moderate risk had significantly greater odds of pneumococcal vaccination (odds ratios [ORs]: 2.42 or 1.36, respectively), as were those who received flu vaccinations (OR: 2.21) or were parents/guardians of a vaccinated child (OR: 6.48). In Brazil, child vaccination appears to be the dominant predictor of adult PPV uptake, followed by influenza vaccination. Higher disease risk was a significant predictor, but most older at-risk adults (89.6%) did not receive PPV.

OBJECTIVES: Pegylated-interferon-α (IFN-α)-based therapies for viral hepatitis C (HCV) are effective, but they are associated with several adverse events (AEs). The primary objectives of this study were to quantify the burden of IFN-α-based treatment and to measure the prevalence and burden of IFN-α-related AEs in Japan. METHODS: A cross-sectional survey was administered online to patients with HCV in 2013. Patients who were currently taking IFN-α-based therapy (n = 188) were compared with patients who were taking a liver protectant but not IFN-α-based therapy (n = 180) and with patients who were untreated (n = 365) on measures of health-related quality of life (using the Hepatitis Quality of Life Questionnaire, version 2), work productivity, and health care resource use, controlling for sociodemographic characteristics and health history. Among patients taking IFN-α-based therapy, the prevalence and burden of AEs was examined on the same set of health outcomes as noted above along with treatment satisfaction and adherence. RESULTS: Compared with untreated patients, patients using IFN-α reported poorer health-related quality of life (physical component summary score, 50.13 vs. 52.04; mental component summary score, 44.12 vs. 47.97), more overall work impairment (32.73 vs. 25.64), more physician visits in the past 6 months (14.51 vs. 8.36), and an increased likelihood of an emergency room visit (odds ratio = 7.25) and hospitalization (odds ratio = 4.05) (all P < 0.05). The mean number of AEs was 6.05 for patients using IFN-α. All AEs were associated with poorer health outcomes (particularly the mental component summary score), and most were also associated with lower treatment satisfaction and medication adherence. CONCLUSIONS: A significant patient burden for IFN-α treatment itself and various AEs was observed. The results suggest that effective, non-IFN-α-based treatments may reduce the societal burden.
RESUMEN
BACKGROUND: The availability of the tyrosine-kinase inhibitor (TKI), imatinib, and later introduction of second generation TKIs, dasatinib and nilotinib, have not only improved clinical outcomes of patients with chronic myeloid leukemia (CML), but also provide multiple therapeutic options for CML patients. Despite the widespread use of these oral therapies, little is known about the impact of different treatment regimens on patient-reported outcomes (PROs) among CML patients. The objective of this study was to assess the impact of patient-reported treatment restrictions and negative medication experiences (NMEs) on satisfaction and other health outcomes among patients with CML treated with oral TKIs. METHODS: Participants recruited from survey panels and patient networks in the United States (US) and Europe completed an online questionnaire. Respondents included adults (≥ 18 years) with chronic-phase CML currently on TKI treatment. Study variables included treatment difficulty (i.e., difficulty in following treatment regimens), CML dietary/dosing requirements, NMEs, and validated PROs assessing treatment satisfaction, health-related quality of life (HRQoL), activity impairment, and non-adherence. Structural equation models assessed associations among variables, controlling for covariates. RESULTS: 303 patients with CML (US n=152; Europe n=151; mean age 51.5 years; 46.2% male) completed the questionnaire. Approximately 30% of patients reported treatment difficulties; treatment difficulty was higher among nilotinib (63.3%) than among dasatinib (2.6%) or imatinib (19.2%) treated patients (p<0.0001). Non-adherence was generally low; however, patients on nilotinib vs. imatinib reported missing doses more often (p<0.05). Treatment satisfaction was associated with significantly increased HRQoL (p<0.05) and lower activity impairment (p<0.01). NMEs were associated with decreased treatment satisfaction (p<0.01) and HRQoL (p<0.05), and greater activity impairment (p<0.01). Higher overall treatment restrictions were associated with greater treatment difficulty (p<0.001), which correlated with non-adherence (p<0.01). CONCLUSIONS: Treatment satisfaction and NMEs are important factors associated with HRQoL among patients with CML. Increased treatment restrictions and associated difficulty may affect adherence with TKIs. Choosing a CML treatment regimen that is simple and conveniently adaptable in patients' normal routine can be an important determinant of HRQoL and adherence.

UNLABELLED: Pain is a complex multidimensional experience that includes overall intensity/magnitude, unpleasantness/bothersomeness (affect), location, and quality. However, there is a paucity of research examining the importance of pain quality to patient functioning; most research focuses only on the intensity and affective components of pain. This study sought to address this gap by examining, in a sample of patients with carpal tunnel syndrome (CTS), the associations between pain quality and 2 domains of patient functioning: pain interference and sleep quality. We found that measures of pain quality contributed to the prediction of pain interference and sleep quality over and above the effects of global pain intensity and unpleasantness. In our sample, both throbbing and itchy pain emerged as contributing the most unique variance to the prediction of patient functioning. The findings indicate that the presence of pain described as throbbing or itchy, regardless of the overall magnitude of pain, may make patients with CTS particularly vulnerable to the negative impact of pain on quality of life. The findings support the need for experimental studies to determine if treatments can be identified that address these 2 pain qualities, and if effective treatments for these qualities in particular result in significant improvement in the quality of life of patients with CTS. PERSPECTIVE: A growing body of research supports the importance of assessing multiple domains of pain in clinical and research settings. The current findings suggest the possibility that, in patients with carpal tunnel syndrome, itchy and throbbing pain may play key roles in patient functioning above and beyond global pain intensity and unpleasantness. More research is needed to confirm this finding, and whether treatments can be identified that address these pain qualities specifically.

OBJECTIVE: To compare, using a within-woman analysis, the severity, duration, and relapse of menstrual vs nonmenstrual episodes of migraine during treatment with usual migraine therapy. BACKGROUND: Studies comparing the clinical characteristics of menstrual and nonmenstrual migraine attacks have yielded conflicting results, contributing to disagreement regarding whether menstrual migraine attacks are clinically more problematic than nonmenstrual migraine attacks. METHODS: Post hoc within-woman analysis of the usual-care phase (month 1) of a 2-month, multicenter, prospective, open-label study at 21 US medical practices (predominantly primary care). Participants were women > or =18 years of age with regular predictable menstrual cycles (28 +/- 4 days) who self-reported a > or =1-year history of migraine attacks occurring between days -2 and +3 (menses onset = day +1) and > or =8 such attacks within the previous 12 cycles. Migraine treatment episodes were categorized as menstrual (occurring on days -2 to +3 of menses) or nonmenstrual (occurring on days +4 to -3 of menses). Pain severity, functional impairment, duration, relapse in 24 hours, and use of rescue medication were compared. Sources of variability (within- or between-patient) were determined using mathematical modeling. The http://www.clinicaltrial.gov code for trial is NCT00904098. RESULTS: Women (n = 153; intent to treat) reported 212 menstrual (59.2%) and 146 nonmenstrual (40.8%) migraine treatment episodes. Compared with nonmenstrual treatment episodes, menstrual episodes were more likely to cause impairment (unadjusted odds ratio, 1.65, 95% CI, 1.05-2.60; P = .03), were longer (unadjusted hazard ratio 1.68; 95% CI, 1.31-2.16; P < .001), and were more likely to relapse within 24 hours (unadjusted odds ratio, 2.66; 95% CI, 1.25-5.68; P = .01). Within-patient effects accounted for only 18-33% of the total variance in these outcomes. CONCLUSIONS: Post hoc, within-woman analysis of migraine treatment episodes categorized based on International Headache Society criteria showed that menstrual treatment episodes were more impairing, longer lasting, and more likely to relapse than nonmenstrual treatment episodes in this selected population of women with frequent menstrual migraine. The current analysis indicates that most of the variability in these outcomes is due to differences between headache types and not within-patient differences for a given type of headache, suggesting that menstrual episodes are potentially treatable. These findings underscore the differences between menstrual and nonmenstrual episodes of migraine and the need to offer effective migraine treatment to women.

UNLABELLED: Item Response Theory (IRT) is being increasingly used to develop and evaluate outcome measures. However, many pain measures, including those that assess pain quality, have yet to be evaluated from the IRT perspective. The current study evaluated the scales of a commonly used measure of pain quality (the Pain Quality Assessment Scale, or PQAS) using IRT analyses in 3 samples of patients with chronic pain. The findings indicated variability in the precision of the scales, suggesting that all 3 of the PQAS scales are precise when pain is severe and that the Paroxysmal and Deep scales but not necessarily the Surface scale are precise when pain is of moderate or lower severity. In addition, 2 potential problems with the 11 (ie, 0 to 10) response levels used for the PQAS items were identified: (1) a high degree of overlap between adjacent response levels and (2) a lack of interval scaling. Research is needed to determine the extent to which these problems do, or do not, threaten the validity of the PQAS items and scales as outcome measures in pain clinical trials. PERSPECTIVE: IRT analyses provide important information about the psychometric and practical qualities of pain measures that is not provided by standard (classical test theory) analyses. IRT analyses of the PQAS subscales indicate that some of the scales are more precise than others at different levels of pain severity and provide important directions for further research to better understand the PQAS. IRT analyses would probably similarly provide important information concerning the utility of other measures commonly used in pain research.

BACKGROUND: Osteoarthritis (OA) and cardiovascular disease (CVD) share age and obesity as risk factors, but may also be linked by pathogenic mechanisms involving metabolic abnormalities and systemic inflammation. This study compared the prevalence of OA and metabolic syndrome (MetS) in subjects with OA versus the general population without OA to determine whether having OA predicts increased cardiovascular risk. METHODS: National Health and Nutrition Examination Survey III data were used as a representative sample of the general US population. Subjects included adults aged > or = 18 years with records of history, physical, radiographic, and laboratory data adequate to assess for diagnoses of MetS and OA. Logistic regression was used to examine the association between MetS and population-weighted variables. RESULTS: The general population sample included 7714 subjects (weighted value representing 174.9 million population), of whom 975 subjects had OA (weighted value 17.5 million) and 6739 did not (weighted value 157.4 million). Metabolic syndrome was prevalent in 59% of the OA population and 23% of the population without OA. Each of the 5 cardiovascular risk factors that comprise MetS was more prevalent in the OA population versus the population without OA: hypertension (75% vs 38%), abdominal obesity (63% vs 38%), hyperglycemia (30% vs 13%), elevated triglycerides (47% vs 32%), and low high-density lipoprotein cholesterol (44% vs 38%). Metabolic syndrome was more prevalent in subjects with OA regardless of sex or race. The association between OA and MetS was greater in younger subjects and diminished with increasing age. Having OA at age 43.8 years (mean age of the general population) was associated with a 5.26-fold (SE = 1.58, P < 0.001) increased risk of MetS. This association remained strong when obesity was controlled for in additional regression models. CONCLUSIONS: Osteoarthritis is associated with an increased prevalence of MetS, particularly in younger individuals. Global cardiovascular risk should be assessed in individuals aged < or = 65 years with OA, and should be considered when prescribing analgesics for OA patients.

UNLABELLED: To examine the use of extended-release (ER) opioids relative to immediate-release (IR) opioids in chronic opioid prescription episodes, pharmacy claim data from a national health plan database were analyzed. Enrollees having at least 1 pharmacy claim for an opioid formulation between June 2003 and May 2006, and at least 1 year of continuous enrollment after their first observed pharmacy claim were included. Opioid prescription episodes were created by combining contiguous days of therapy, allowing for a maximum of 7 days between refills (>or=8 d = new episode). Outcomes are reported in the form of probabilities and odds ratios (ORs). A total of 3,993,011 opioid prescription episodes were derived from 1,967,898 enrollees. Overall, prescription episodes involving IR preparations (97.7%) were more prevalent than episodes using ER preparations (2.3%). The odds of an ER preparation being prescribed chronically (>or=60 d) were approximately 11 times that of an IR preparation (OR = 10.7); however, the majority of chronic prescription episodes used IR formulations (84.8%). When stratified by prescriber type (specialist vs nonspecialists), the probability of a specialist prescribing ER opioids in these chronic prescription episodes was 19.1% versus 13.7% for nonspecialists. Specialists were about 50% more likely to prescribe ER opioids relative to nonspecialists (OR = 1.49). PERSPECTIVE: This analysis suggests that the availability of pain-treatment guidelines, recommendations, and education alone may not be enough to influence opioid-prescribing practices in the treatment of chronic pain.

OBJECTIVE: In controlled trials of analgesics, the primary outcome variable is most often a measure of global pain intensity. However, because pain is associated with a variety of pain sensations, the effects of analgesic treatments on different sensations could go undetected if specific pain qualities are not assessed. This study sought to evaluate the utility of assessing the multiple components of non-neuropathic pain in an analgesic clinical trial. METHODS: A secondary analysis was performed using data from a clinical trial involving 140 individuals with low back pain who were converted from prestudy opioids to an equianalgesic dose of an extended release (ER) formulation of oxymorphone (OPANA ER), which was then titrated to a stable dose [defined as visual analog scale Asunto(s)

RESUMEN
OBJECTIVE: To provide a better empirical understanding of the dimensionality of neuropathic and non-neuropathic pain quality. METHOD: An exploratory factor analysis (FA) was performed with baseline pain quality data [assessed using the Pain Quality Assessment Scale (PQAS)] from patients with osteoarthritis of the knee (n=368) and low back pain (n=455) who had participated in a series of analgesic clinical trials. The results of the FA were then confirmed in a sample of patients with neuropathic pain secondary to carpal tunnel syndrome (n=138). Comparisons between the diagnostic groups on scale scores derived from the FA results were also made using t tests. RESULTS: Three clear pain quality factors emerged that seemed to represent (1) paroxysmal pain sensations (PQAS descriptors: shooting, sharp, electric, hot, and radiating), (2) superficial pain (itchy, cold, numb, sensitive, and tingling), and (3) deep pain (aching, heavy, dull, cramping, and throbbing). The PQAS tender pain item did not load strongly on any of the 3 factors. DISCUSSION: The findings support the hypothesis that pain qualities cluster into distinct groups. If replicated in additional samples, the pain quality domains identified may provide clinicians and researchers with a useful way to summarize data from pain quality measures, and may also provide meaningful end points that would allow for treatment differentiation between various pharmacologic entities.
