RESUMO
OBJECTIVES: This study had two objectives: to examine associations between extended high-frequency (EHF) thresholds, demographic factors (age, sex, race/ethnicity), risk factors (cardiovascular, smoking, noise exposure, occupation), and cognitive abilities; and to determine variance explained by EHF thresholds for speech perception in noise, self-rated workload/effort, and self-reported hearing difficulties. DESIGN: This study was a retrospective analysis of a data set from the MUSC Longitudinal Cohort Study of Age-related Hearing Loss. Data from 347 middle-aged adults (45 to 64 years) and 694 older adults (≥ 65 years) were analyzed for this study. Speech perception was quantified using low-context Speech Perception In Noise (SPIN) sentences. Self-rated workload/effort was measured using the effort prompt from the National Aeronautics and Space Administration-Task Load Index. Self-reported hearing difficulty was assessed using the Hearing Handicap Inventory for the Elderly/Adults. The Wisconsin Card Sorting Task and the Stroop Neuropsychological Screening Test were used to assess selected cognitive abilities. Pure-tone averages representing conventional and EHF thresholds between 9 and 12 kHz (PTA(9 - 12 kHz)) were utilized in simple linear regression analyses to examine relationships between thresholds and demographic and risk factors or in linear regression models to assess the contributions of PTA(9 - 12 kHz) to the variance among the three outcomes of interest. Further analyses were performed on a subset of individuals with thresholds ≤ 25 dB HL at all conventional frequencies to control for the influence of hearing loss on the association between PTA(9 - 12 kHz) and outcome measures. RESULTS: PTA(9 - 12 kHz) was higher in males than females, and was higher in White participants than in racial Minority participants. Linear regression models showed the associations between cardiovascular risk factors and PTA(9 - 12 kHz) were not statistically significant. Older adults who reported a history of noise exposure had higher PTA(9 - 12 kHz) than those without a history, while associations between noise history and PTA(9 - 12 kHz) did not reach statistical significance for middle-aged participants. Linear models adjusting for age, sex, race and noise history showed that higher PTA(9 - 12 kHz) was associated with greater self-perceived hearing difficulty and poorer speech recognition scores in noise for both middle-aged and older participants. Workload/effort was significantly related to PTA(9 - 12 kHz) for middle-aged, but not older, participants, while cognitive task performance was correlated with PTA(9 - 12 kHz) only for older participants. In general, PTA(9 - 12 kHz)did not account for additional variance in outcome measures as compared to conventional pure-tone thresholds, with the exception of self-reported hearing difficulties in older participants. Linear models adjusting for age and accounting for subject-level correlations in the subset analyses revealed no association between PTA(9 - 12 kHz)and outcomes of interest. CONCLUSIONS: EHF thresholds show age-, sex-, and race-related patterns of elevation that are similar to what is observed for conventional thresholds. The current results support the need for more research to determine the utility of adding EHF thresholds to routine audiometric assessment with middle-aged and older adults.
RESUMO
OBJECTIVE: To estimate the marginal cost differences and care delivery process of a telerehabilitation vs outpatient session. DESIGN: This study used a time-driven activity-based costing approach including (1) observation of rehabilitation sessions and creation of manual time stamps, (2) structured and recorded interviews with 2 occupational therapists familiar with outpatient therapy and 2 therapists familiar with telerehabilitation, (3) collection of standard wages for providers, and (4) the creation of an iterative flowchart of both an outpatient and telerehabilitation session care delivery process. SETTING: Telerehabilitation and outpatient therapy evaluation. PARTICIPANTS: Three therapists familiar with care deliver for telerehabilitation or outpatient therapy (N=3). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Marginal cost difference between telerehabilitation and outpatient therapy evaluations. RESULTS: Overall, telerehabilitation ($225.41) was more costly than outpatient therapy ($168.29) per session for a cost difference of $57.12. Primary time drivers of this finding were initial phone calls (0 minutes for OP therapists vs 35 minutes for TR) and post documentation (5 minutes for OP vs 30 minutes for TR) demands for telerehabilitation. CONCLUSIONS: Telerehabilitation is an emerging platform with the potential to reduce costs, improve health care inequities, and facilitate better patient outcomes. Improvements in documentation practices, staffing, technology, and reimbursement structuring would allow for a more successful translation.

Community Health Worker (CHW) interventions have shown potential to reduce inequities for underserved populations. However, there is a lack of support for CHW integration in the delivery of health care. This may be of particular importance in rural areas in the Unites States where access to care remains problematic. This review aims to describe CHW interventions and their outcomes in rural populations in the US. Peer reviewed literature was searched in PubMed and PsycINFO for articles published in English from 2015 to February 2021. Title and abstract screening was performed followed by full text screening. Quality of the included studies was assessed using the Downs and Black score. A total of 26 studies met inclusion criteria. The largest proportion were pre-post program evaluation or cohort studies (46.2%). Many described CHW training (69%). Almost a third (30%) indicated the CHW was integrated within the health care team. Interventions aimed to provide health education (46%), links to community resources (27%), or both (27%). Chronic conditions were the concern for most interventions (38.5%) followed by women's health (34.6%). Nearly all studies reported positive improvement in measured outcomes. In addition, studies examining cost reported positive return on investment. This review offers a broad overview of CHW interventions in rural settings in the United States. It provides evidence that CHW can improve access to care in rural settings and may represent a cost-effective investment for the healthcare system.

Introduction: Cost studies of telehealth (TH) and virtual visits are few and report mixed results of the economic impact of virtual care and TH. Largely missing from the literature are studies that identify the cost of delivering TH versus in-person care. The objective was to demonstrate a modified time-driven activity-based costing (TDABC) approach to compare weighted labor cost of an in-person pediatric clinic sick visit before COVID-19 to the same virtual and in-person sick-visit during COVID-19. Methods: We examined visits before and during COVID-19 using: (1) recorded structured interviews with providers; (2) iterative workflow mapping; (3) electronic health records time stamps for validation; (4) standard cost weights for wages; and (5) clinic CPT billing code mix for complexity weighs. We examined the variability in estimated time using a decision tree model and Monte Carlo simulations. Results: Workflow charts were created for the clinic before COVID-19 and during COVID-19. Using TDABC and simulations for varying time, the weighted cost of clinic labor for sick visit before COVID-19 was $54.47 versus $51.55 during COVID-19. Discussion: The estimated mean labor cost for care during the pandemic has not changed from the pre-COVID period; however, this lack of a difference is largely because of the increased use of TH. Conclusions: Our TDABC approach is feasible to use under virtual working conditions; requires minimal provider time for execution; and generates detailed cost estimates that have "face validity" with providers and are relevant for economic evaluation.

OBJECTIVE: To characterize health care utilization and costs associated with care after diagnosis of Kawasaki disease including adherence to guidelines for echocardiograms. STUDY DESIGN: We analyzed children hospitalized for Kawasaki disease using 2015-2017 national Truven MarketScan commercial claims data. The mean 90-day prehospitalization utilization and costs were quantified and compared with the 90 days posthospitalization via Wilcoxon 2-sample test. Adherence to echocardiogram guidelines was examined using multivariable logistic regression to identify factors associated with adherence. RESULTS: The mean total payments 90 days prior to hospitalization ($2090; n = 360) were significantly lower than those after discharge ($3778), though out of pocket costs were higher ($400 vs $270) (P < .0001). There was an increase in office visits, medical procedures, and echocardiograms after discharge. A majority of health care utilization before hospitalization occurred in the 7 days immediately prior to the date of admission; 51% obtained an echocardiogram within the first 2 weeks, and 14% were completely adherent with recommendations. Children with greater utilization prior to admission were more likely to adhere to American Heart Association guidelines for follow-up echocardiograms (OR 1.03, 95% CI 1.01-1.06). CONCLUSIONS: Outpatient health care expenditure nearly doubles after Kawasaki disease hospital discharge when compared with prehospitalization, suggesting the financial ramifications of this diagnosis persist beyond costs incurred during hospitalization. A significant portion of patients do not receive guideline recommended follow-up echocardiograms. This issue should be explored in more detail given the morbidity and mortality associated with this diagnosis.

Background: Since 2003, the University of Mississippi Medical Center has operated a robust telehealth emergency department (ED) network, TelEmergency, which enhances access to emergency medicine-trained physicians at participating rural hospitals. TelEmergency was developed as a cost-control measure for financially constrained rural hospitals to improve access to quality, emergency care. However, the literature remains unclear as to whether ED telehealth services can be provided at lower costs compared with traditional in-person ED services. Introduction: Our objective was to empirically determine whether TelEmergency was associated with lower ED costs at rural hospitals when compared with similar hospitals without TelEmergency between 2010 and 2017. Materials and Methods: A panel of data for 2010-2017 was constructed at the hospital level. Hospitals with TelEmergency (n = 14 hospitals; 112 hospital-years) were compared with similar hospitals that did not use TelEmergency from Arkansas, Georgia, Mississippi, and South Carolina (n = 102; 766 hospital-years), matched using Coarsened Exact Matching. The relationship between total ED costs and treatment (e.g., participation in TelEmergency) was predicted using generalized estimating equations with a Poisson distribution, a log link, an exchangeable error term, and robust standard errors. Results: After controlling for ownership type, critical access hospital status, year, and size, TelEmergency was associated with an estimated 31.4% lower total annual ED costs compared with similar matched hospitals that did not provide TelEmergency. Conclusions: TelEmergency utilization was associated with significantly lower total annual ED costs compared with similarly matched hospitals that did not utilize TelEmergency. These findings suggest that access to quality ED care in rural communities can occur at lower costs.

Background/Objective: An efficient and accurate strategy for identifying children with asthma at high-risk for exacerbation is needed. The objective of this study is to conduct a longitudinal examination of the asthma medication ratio (AMR) (#of controller medication claims/(# of controller medication claims + # of rescue medication claims)) in Medicaid-funded children with asthma. This measure has the potential to be a near real-time risk assessment tool.Methods: We conducted a retrospective analysis of 2013-2014 Truven Health Medicaid data. We analyzed pharmacy and medical claims for a cohort of children with asthma. We identified patients age 2-17 years with at least one claim for an inhaled corticosteroid. We calculated an AMR for rolling 3-month periods and examined the proportion who were classified as low risk (AMR ≥ .5), high-risk (AMR < .5) and no medication claims (no asthma medication claims). Using logistic regression, we tested how the AMR predicted severe exacerbations.Results: 214,452 eligible children were identified. The mean age is 7.8 years. 8-9% had a high-risk AMR in any given period. High-risk AMR is associated with increased odds of a severe exacerbation in the subsequent 3 months (compared to all other children) (OR 1.7-1.9 depending on time period evaluated).Conclusions: In this analysis of Medicaid-insured children with asthma, we found that the AMR is a reliable predictor of exacerbations. This will inform the development of an AMR-based risk assessment and communication intervention.

OBJECTIVES: The present study evaluates the items of the Hearing Handicap Inventory for the Elderly and Hearing Handicap Inventory for Adults (HHIE/A) using Mokken scale analysis (MSA), a type of nonparametric item response theory, and develops updated tools with optimal psychometric properties. DESIGN: In a longitudinal study of age-related hearing loss, 1447 adults completed the HHIE/A and audiometric testing at baseline. Discriminant validity of the emotional consequences and social/situational effects subscales of the HHIE/A was assessed, and nonparametric item response theory was used to explore dimensionality of the items of the HHIE/A and to refine the scales. RESULTS: The HHIE/A items form strong unidimensional scales measuring self-perceived hearing handicap, but with a lack of discriminant validity of the two distinct subscales. Two revised scales, the 18-item Revised Hearing Handicap Inventory and the 10-item Revised Hearing Handicap Inventory-Screening, were developed from the common items of the original HHIE/A that met the assumptions of MSA. The items on both of the revised scales can be ordered in terms of increasing difficulty. CONCLUSIONS: The results of the present study suggest that the newly developed Revised Hearing Handicap Inventory and Revised Hearing Handicap Inventory-Screening are strong unidimensional, clinically informative measures of self-perceived hearing handicap that can be used for adults of all ages. The real-data example also demonstrates that MSA is a valuable alternative to classical psychometric analysis.

Background: Studies show that telestroke (TS) improves rural access to care and outcome for stroke patients receiving TS services, but population health impacts of TS are not known. We examine impacts associated with South Carolina's (SC) statewide TS network on an entire state population of patients suffering acute ischemic stroke (AIS) as TS became available across SC counties. Methods: A population health study using Donabedian's conceptual model and an ecological design to describe the change observed over time in use of thrombolysis and endovascular therapy (EVT) as the SC TeleStroke Network (SCTN) diffused across SC counties. Changes in county rates of stroke mortality and discharge destination are reported. The unit of interest is the population rate for AIS patients living in a SC county. Patients' county of residence at the time of hospitalization defined county cohorts. Relative risks were estimated using logistic regression adjusted for age >75 years. Results: Overall tissue plasminogen activator (tPA) rate was 6.28%, and EVT rate was 1.10%. Patients living where SCTN was available had a 25% higher likelihood of receiving tPA (adjusted relative risk [ARR] = 1.25, 95% confidence interval [CI] = 1.15-1.36) and lower risks of mortality (ARR = 0.91; 95% CI = 0.84-0.99) or discharge to skilled nursing (ARR = 0.93; 95% CI = 0.89-0.97). Conclusions: TS diffusion affects the structure of the health system serving a county, as well as the processes of care delivered in the emergency department; these changes are associated with measurable population health improvements. Results support a population benefit of TS implementation.

OBJECTIVES: Although many individuals with hearing loss could benefit from intervention with hearing aids, many do not seek or delay seeking timely treatment after the onset of hearing loss. There is limited data-based evidence estimating the delay in adoption of hearing aids with anecdotal estimates ranging from 5 to 20 years. The present longitudinal study is the first to assess time from hearing aid candidacy to adoption in a 28-year ongoing prospective cohort of older adults, with the additional goal of determining factors influencing delays in hearing aid adoption, and self-reported successful use of hearing aids. DESIGN: As part of a longitudinal study of age-related hearing loss, a wide range of demographic, biologic, and auditory measures are obtained yearly or every 2 to 3 years from a large sample of adults, along with family, medical, hearing, noise exposure, and hearing aid use histories. From all eligible participants (age ≥18; N = 1530), 857 were identified as hearing aid candidates either at baseline or during their participation, using audiometric criteria. Longitudinal data were used to track transition to hearing aid candidacy and hearing aid adoption. Demographic and hearing-related characteristics were compared between hearing aid adopters and nonadopters. Unadjusted estimated overall time (in years) to hearing aid adoption and estimated delay times were stratified by demographic and hearing-related factors and were determined using a time-to-event analysis (survival analysis). Factors influencing rate of adoption in any given time period were examined along with factors influencing successful hearing aid adoption. RESULTS: Age, number of chronic health conditions, sex, retirement status, and education level did not differ significantly between hearing aid adopters and nonadopters. In contrast, adopters were more likely than nonadopters to be married, of white race, have higher socioeconomic status, have significantly poorer higher frequency (2.0, 3.0, 4.0, 6.0, and 8.0 kHz) pure-tone averages, poorer word recognition in quiet and competing multi-talker babble, and reported more hearing handicap on the Hearing Handicap Inventory for the Elderly/Adults emotional and social subscales. Unadjusted estimation of time from hearing aid candidacy to adoption in the full participant cohort was 8.9 years (SE ± 0.37; interquartile range = 3.2-14.9 years) with statistically significant stratification for race, hearing as measured by low- and high-frequency pure-tone averages, keyword recognition in low-context sentences in babble, and the Hearing Handicap Inventory for the Elderly/Adults social score. In a subgroup analysis of the 213 individuals who adopted hearing aids and were assigned a success classification, 78.4% were successful. No significant predictors of success were found. CONCLUSIONS: The average delay in adopting hearing aids after hearing aid candidacy was 8.9 years. Nonwhite race and better speech recognition (in a more difficult task) significantly increased the delay to treatment. Poorer hearing and more self-assessed hearing handicap in social situations significantly decreased the delay to treatment. These results confirm the assumption that adults with hearing loss significantly delay seeking treatment with hearing aids.

The objective of this quality improvement study was to evaluate whether electronic health record system timers and event logs can measure the efficiency and quality of a clinical process in an electronic health record. Using an experimental pre- and post-nonrandomized prospective cohort design, the researchers introduced a newly defined admission patient history essential data set and examined the electronic health record event files and timers to analyze the nursing experience from an efficiency and quality perspective. The researchers evaluated efficiency by measuring the time and clicks required to complete an admission history. The average active time spent documenting the admission patient history decreased by 72% from the preintervention measure (mean = 9.30 minutes) to the postintervention measure (mean = 2.55 minutes). The number of clicks decreased by 76% from the preintervention number of clicks (mean = 151.5) to the postintervention number of clicks (mean = 35.93). The quality of documentation was measured as the proportion of completed essential items and the frequency of completing an assessment in one sequence. The capture of essential data elements improved by almost 6%, and admission patient history data completed in one sequence increased by 24%. These study results demonstrate that system timers and event logs can measure the preintervention and postintervention changes in efficiency and quality of a defined clinical workflow into an electronic health record.

OBJECTIVE: To determine if improvement in Inhaled Corticosteroid (ICS) prescribing in the pediatric emergency department (PED) can be sustained after transition from intense intervention to low-intervention phase, and to determine ICS fill rates. METHODS: A Quality Improvement (QI) project began in Aug 2012. Results through Feb 2014 were previously published. In Feb 2014 interventions were scaled back to determine the sustainability of QI success. Eligible patients included children aged 2-17 seen in the PED for asthma between Feb 2014 and Sept 2016. The primary change when moving to the low-intervention phase was stopping monthly attending feedback. The primary outcome was the proportion of patients who were prescribed an ICS at the time of PED discharge. The secondary objective of this study was to determine the proportion of patients who filled their ICS prescription in the 6 months following Emergency Department (ED) visit. RESULTS: The goal rate of ICS prescribing was 75%. After transition to the low-intervention phase, the ICS prescribing rate was maintained at a median of 79% through Sept 2016. ICS fill rate in the first 30 days following ED visit was 89%, although this quickly fell to below 40% for months 2-6. CONCLUSIONS: The ICS prescribing rate remained the goal of 75% over a 2.5-year period after transition to a low-intervention phase. High ICS fill rates immediately after ED visit have been demonstrated. However, rapid decline in these rates over subsequent months suggests a need for future efforts to focus on long-term ICS adherence among children with ED visits for asthma.

OBJECTIVE: To improve the practical use of the short forms (SFs) developed from the item bank, we compared the measurement precision of the 4- and 8-item SFs generated from a motor item bank composed of the FIM and the Minimum Data Set (MDS). DESIGN: The FIM-MDS motor item bank allowed scores generated from different instruments to be co-calibrated. The 4- and 8-item SFs were developed based on Rasch analysis procedures. This article compared person strata, ceiling/floor effects, and test SE plots for each administration form and examined 95% confidence interval error bands of anchored person measures with the corresponding SFs. We used 0.3 SE as a criterion to reflect a reliability level of .90. SETTING: Veterans' inpatient rehabilitation facilities and community living centers. PARTICIPANTS: Veterans (N=2500) who had both FIM and the MDS data within 6 days during 2008 through 2010. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Four- and 8-item SFs of FIM, MDS, and FIM-MDS motor item bank. RESULTS: Six SFs were generated with 4 and 8 items across a range of difficulty levels from the FIM-MDS motor item bank. The three 8-item SFs all had higher correlations with the item bank (r=.82-.95), higher person strata, and less test error than the corresponding 4-item SFs (r=.80-.90). The three 4-item SFs did not meet the criteria of SE <0.3 for any theta values. CONCLUSIONS: Eight-item SFs could improve clinical use of the item bank composed of existing instruments across the continuum of care in veterans. We also found that the number of items, not test specificity, determines the precision of the instrument.

This study compared disability levels between community-dwelling adults in the United States and South Korea using two national surveys of the United States and Korean National Health and Examination Survey (NHANES and KNHANES). The Rasch common-item equating method was used to create the same measurement framework and compared average disability levels. The disability levels between the two countries were estimated using the current disability estimation method (percentage of people having disability based on a single question). A higher percentage of American adults (20.5%) showed disability than the Korean adults (9.6%) based on the current estimation method; however, using the Rasch model American adults had significantly less disability (Mean = -3.00 logits, SD = 1.67) than the Korean adults (Mean = -2.48 logits, SD = 2.13). Complementary to comparisons of the frequency of disability, comparison of the combined magnitude and strength of disability across countries provides new information that may better inform public health and policy decisions.

PURPOSES: To compare measurement accuracy of test forms with varied number of items (13, 8, and 4 items) generated from the self-care physical function item bank composed of Functional Independence Measure (FIM™) and the Minimum Data Set (MDS). METHODS: Retrospective data analysis of 2499 Veterans who completed both FIM and MDS within 6 days. We compared measurement accuracy between the converted FIM (FIMc) motor score generated from the MDS and the original FIM (FIMa) motor score (13 items) at: (a) individual-level using point differences, and (b) group-level using function-related group (FRG). RESULTS: The differences of mean FIMa and FIMc scores were between 0.05 and 1.07 points for all test forms. Over 81% of FIMc from MDS_13 were within 15 points of the FIMa. 81-90% of FRGs generated by the FIM short forms was identical to those generated by the FIMa for stroke, lower limb amputation, knee and hip replacement; and 59.9-90.5% by all MDS test forms. All MDS test forms had above 74% agreement with same or adjacent FMGs (ICC 0.65-0.91). CONCLUSIONS: The accuracy is dependent on the comparison level (i.e., individual or group), length of the test and which FRG is used. Our results partially support using existing instruments-without decreasing the number of the items-to generate a continuum of care measurement.

BACKGROUND: An accurate perception of weight status is important to prevent childhood obesity. OBJECTIVE: We investigated whether parents and health professionals accurately identify children's weight status. METHODS: On the 2012 National Health and Nutrition Examination Survey: National Youth Fitness Survey, parents and health professionals rated the same child's weight status as overweight or healthy. The sensitivity and specificity of their answers were computed by comparing parents' and health professionals' ratings to the age growth chart from the US Centers for Disease Control and Prevention. RESULTS: Participants were 1571 children. Parents' sensitivity and specificity were 0.386 and 0.992, respectively. Health professionals' sensitivity and specificity were 0.343 and 0.981, respectively. CONCLUSIONS: Parents and health professionals demonstrate low sensitivity in identifying children's weight status. Health professionals should use the Centers for Disease Control and Prevention categories to more accurately identify children who are overweight.

OBJECTIVE: Administrative data are used for research, quality improvement, and health policy in severe sepsis. However, there is not a sepsis-specific tool applicable to administrative data with which to adjust for illness severity. Our objective was to develop, internally validate, and externally validate a severe sepsis mortality prediction model and associated mortality prediction score. DESIGN: Retrospective cohort study using 2012 administrative data from five U.S. states. Three cohorts of patients with severe sepsis were created: 1) International Classification of Diseases, 9th Revision, Clinical Modification codes for severe sepsis/septic shock, 2) Martin approach, and 3) Angus approach. The model was developed and internally validated in International Classification of Diseases, 9th Revision, Clinical Modification, cohort and externally validated in other cohorts. Integer point values for each predictor variable were generated to create a sepsis severity score. SETTING: Acute care, nonfederal hospitals in New York, Maryland, Florida, Michigan, and Washington. SUBJECTS: Patients in one of three severe sepsis cohorts: 1) explicitly coded (n = 108,448), 2) Martin cohort (n = 139,094), and 3) Angus cohort (n = 523,637) INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Maximum likelihood estimation logistic regression to develop a predictive model for in-hospital mortality. Model calibration and discrimination assessed via Hosmer-Lemeshow goodness-of-fit and C-statistics, respectively. Primary cohort subset into risk deciles and observed versus predicted mortality plotted. Goodness-of-fit demonstrated p value of more than 0.05 for each cohort demonstrating sound calibration. C-statistic ranged from low of 0.709 (sepsis severity score) to high of 0.838 (Angus cohort), suggesting good to excellent model discrimination. Comparison of observed versus expected mortality was robust although accuracy decreased in highest risk decile. CONCLUSIONS: Our sepsis severity model and score is a tool that provides reliable risk adjustment for administrative data.

OBJECTIVES: Our objectives were to evaluate trends in percutaneous endoscopic gastrostomy (PEG) tube placement rate and timing in acute stroke patients. We hypothesized that noncompliance with clinical practice guidelines for timing of tube placement and an increase in placement occurred because of a decrease in length of hospital stay. METHODS: We conducted a retrospective observational study of archival hospital billing data from the Florida state inpatient healthcare cost and utilization project database from 2001 to 2012 for patients with a primary diagnosis of stroke. Outcome measures were timing of PEG tube placements by year (2006-2012), rate of placements by year (2001-2012), and length of hospital stay. Univariate analyses and simple and multivariable logistic regression analyses were conducted. RESULTS: The timing of gastrostomy tube placement remained stable with a median of 7 days post admission from 2006 through 2012. The proportion of tubes that were placed at or after 14 days and thereby met the guideline recommendations varied from 14.09% in 2006 to 13.41% in 2012. The rate of tube placement in stroke patients during the acute hospital stay decreased significantly by 25% from 6.94% in 2001 to 5.22% in 2012 (P < .0001). The length of hospital stay for all stroke patients decreased over the study period (P < .0001). CONCLUSIONS: The vast majority of PEG tube placements happen earlier than clinical practice guidelines recommend. Over the study period, the rate of tubes placed in stroke patients decreased during the acute hospital stay despite an overall reduced length of stay.

This study demonstrated the development of a measurement model for gross upper-extremity function (GUE). The dependent variable was the Rasch calibration of the 27 ICF-GUE test items. The predictors were object weight, lifting distance from floor, carrying, and lifting. Multiple regression was used to investigate the contribution that each independent variable makes to the model with 203 outpatients. Object weight and lifting distance were the only statistically and clinically significant independent variables in the model, accounting for 83% of the variance (p < 0.01). The model indicates that, with each one pound increase in object weight, item challenge increases by 0.16 (p < 0.00) logits, and with each one inch increase in distance lifted from floor, item challenge increased by 0.02 logits (p < 0.02). The findings suggest that the majority of the variance of the measurement model for the ICF-GUE can be explained by object weight and distance lifted from the floor.

BACKGROUND AND PURPOSE: Randomized trials have indicated a benefit for endovascular therapy in appropriately selected stroke patients at 3 months, but data regarding outcomes at 12 months are currently lacking. METHODS: We compared functional and quality-of-life outcomes at 12 months overall and by stroke severity in stroke patients treated with intravenous tissue-type plasminogen activator followed by endovascular treatment as compared with intravenous tissue-type plasminogen activator alone in the Interventional Management of Stroke III Trial. The key outcome measures were a modified Rankin Scale score ≤2 (functional independence) and the Euro-QoL EQ-5D, a health-related quality-of-life measure. RESULTS: 656 subjects with moderate-to-severe stroke (National Institutes of Health Stroke Scale ≥8) were enrolled at 58 centers in the United States (41 sites), Canada (7), Australia (4), and Europe (6). There was an interaction between treatment group and stroke severity in the repeated measures analysis of modified Rankin Scale ≤2 outcome (P=0.039). In the 204 participants with severe stroke (National Institutes of Health Stroke Scale ≥20), a greater proportion of the endovascular group had a modified Rankin Scale ≤2 (32.5%) at 12 months as compared with the intravenous tissue-type plasminogen activator group (18.6%, P=0.037); no difference was seen for the 452 participants with moderately severe strokes (55.6% versus 57.7%). In participants with severe stroke, the endovascular group had 35.2 (95% confidence interval: 2.1, 73.3) more quality-adjusted-days over 12 months as compared with intravenous tissue-type plasminogen activator alone. CONCLUSIONS: Endovascular therapy improves functional outcome and health-related quality-of-life at 12 months after severe ischemic stroke.
