Relevance of chest radiography in pediatric inpatients with asthma.

INTRODUCTION: The goals of this study are to identify factors associated with ordering of chest radiographs (CXR's) in children hospitalized with acute asthma exacerbations and determine the overall clinical impact of these CXR's. METHODS: A retrospective study was performed with children ≥ 2 years of age admitted from our emergency department (ED) between 6/1/2011 and 5/31/2012 with a primary diagnosis of acute asthma exacerbation or status asthmaticus. Patients were excluded if they had been on antibiotics prior to the emergency visit, received continuous albuterol or intravenous magnesium during the hospitalization, or had another chronic disease affecting lung function. RESULTS: 180 of the 405 children in the study (44%) had CXR's ordered, of which 18 (10%) had imaging that altered the patient's treatment plan. There were six cases of radiologist-diagnosed pneumonia, nine cases of atelectasis treated with antibiotics and three cases of pneumothorax. Factors associated with CXR ordering were: fever at home or in the ED (OR 4.5, 95% CI 2.8-7.4), triage oxygen saturation less than or equal to 92% (OR 1.8, 95% CI 1.2-2.7) and age 4 years or less (OR 2.3, 95% CI 1.4-3.7). Patients with treatment-altering CXR's were more likely to have oxygen saturations less than or equal to 92% (OR 4.2, 95% CI 1.4-13.0; p = 0.006) or fever in the ED (OR 3.8, 95% CI 1.0-13.6; p < 0.05). No patients with triage oxygen saturation above 96% had a treatment-altering CXR. CONCLUSIONS: The majority of CXR's ordered in pediatric inpatients with asthma exacerbation do not provide clinically relevant information.

Exploring pre-school vision screening in primary care offices in Alabama.

PURPOSE: To investigate practices, barriers, and facilitators of universal pre-school vision screening (PVS) at pediatric primary care offices. METHODS: Focus group sessions (FGS) were moderated on-site at nine pediatric practices. A semi-structured topic guide was used to standardize and facilitate FGS. Discussions were audiotaped, and transcriptions were used to develop themes. All authors reviewed and agreed on the resultant themes. RESULTS: FGS included 13 physicians and 32 nurses/certified medical assistants (CMAs), of whom 82% personally conducted some facet of PVS. In all practices, nurses/CMAs tested visual acuity (most using a non-recommended test), and physicians completed vision screening with external observation, fix/follow, red reflex, and cover test. Facilitators included (1) accepting that PVS is a routine part of the well-child visit, and (2) using an electronic medical record with prompts to record acuity (eight of nine practices). Barriers were related to difficulty testing pre-schoolers, distractions in the office setting, time constraints, and limited reimbursement. CONCLUSIONS: Responsibility for PVS is shared by physicians and nurses/CMAs; thus, interventions to improve PVS should target both. Few practices are aware of new evidence-based PVS tests; thus, active translational efforts are needed to change current primary care practices.

Knowledge, attitudes, and environment: what primary care providers say about pre-school vision screening.

PURPOSE: To evaluate knowledge, attitudes, and environment of primary care providers, and to develop a conceptual framework showing their impact on self-reported pre-school vision screening (PVS) behaviors. METHODS: Eligible primary care providers were individuals who filed claims with Medicaid agencies in Alabama, South Carolina, or Illinois, for at least eight well child checks for children aged 3 or 4 years during 1 year. Responses were obtained on-line from providers who enrolled in the intervention arm of a randomized trial to improve PVS. We calculated a summary score per provider per facet: (1) for behavior and knowledge, each correct answer was assigned a value of +1; and (2) for attitudes and environment, responses indicating support for PVS were assigned a value of +1, and other responses were assigned -1. RESULTS: Responses were available from 53 participants (43 of 49 enrolled pediatricians, 8 of 14 enrolled family physicians, one general physician, and one nurse practitioner). Recognizing that amblyopia often presents without outward signs was positively related to good PVS: [odds ratio (OR) = 3.9; p = 0.06]. Reporting that "preschool VS interrupts patient flow" posed a significant barrier (OR = 0.2; p = 0.05). Providers with high summed scores on attitudes (OR = 6.0; p = 0.03), or knowledge and attitudes (OR = 11.4; p < 0.001) were significantly more likely to report good PVS behavior. There was a significant trend between the number of "good" scores on knowledge, attitudes or environment, and "good" PVS behavior (p = 0.04). CONCLUSIONS: PVS is influenced by positive attitudes, especially when combined with knowledge about amblyopia. Interventions to improve PVS should target multiple facets, emphasizing (1) asymptomatic children are at risk for amblyopia, (2) specific evidence-based tests have high testability and sensitivity for amblyopia in pre-school children, and (3) new tests minimize interruptions to patient flow.

Experimental study on drying and moisture re-adsorption kinetics of an Indonesian low rank coal.

The drying kinetics of an Indonesian low rank coal and moisture re-adsorption of the dried coal using a thermobalance and a climatic chamber were investigated. Results show that the drying kinetics is best represented by two stages, as a constatnt rate stage followed by a rate decay stage. The water removal rate is dependent mainly on drying temperature and coal sample size. The apparent activation energy (E) of drying was 26.58 kJ/mol. A rate equation for drying of the coal was obtained from the experimental data. The moisture re-adsorption rate was dependent on drying temperature, coal particle size, and relative humidity of the atmosphere.

The Employment Experience of Recent Graduates From US Radiation Oncology Training Programs: The Practice Entry Survey Results From 2012 to 2017.

PURPOSE: The Practice Entry Survey presentation is a highly anticipated session for the radiation oncology (RO) resident at the American Society for Radiation Oncology annual meeting. Each year the senior author reports the employment outcomes and job market experiences for the most recently graduated RO residents. METHODS: The Practice Entry Survey has been continuously administered annually to graduated RO residents since 1984 via the Association of Residents in Radiation Oncology directory. Six years of individual-level data, from 2012 to 2017, were readily available for analysis. The questionnaire queries the workforce placement experience and collects debt, salary, and benefits information. Respondents were subgrouped by practice type (academic vs private practice), and results were tested for trends over time. RESULTS: Survey data were collected from 302 recently graduated residents. There were 7 in fellowship and 1 practicing internationally, leaving 294 eligible for analysis. They identified themselves as working in either an academic setting (n = 150 [51%]) or private practice (n = 144 [49%]). First-year salaries for those in private practice were more than those in academics ($303,000; [interquartile range, $270,000-$375,000] versus $280,000 [interquartile range, $260,000-$325,000]; P < .01). With regard to the job search, 21.8% of respondents found their jobs through the online American Society for Radiation Oncology Career Center, while most respondents, 77.2%, found their jobs through other means. Respondents also ranked the items they found to be most helpful during the interview process. CONCLUSIONS: These data can help gauge the competitiveness of an offer as well as what to expect during the job hunt and interview process.

Low-Cost Carbon Fibre Derived from Sustainable Coal Tar Pitch and Polyacrylonitrile: Fabrication and Characterisation.

Preparation of high-value pitch-based carbon fibres (CFs) from mesophase pitch precursor is of great importance towards low-cost CFs. Herein, we developed a method to reduce the cost of CFs precursor through incorporating high loading of coal tar pitch (CTP) into polyacrylonitrile (PAN) polymer solution. The CTP with a loading of 25% and 50% was blended with PAN and their spinnability was examined by electrospinning process. The effect of CTP on thermal stabilization and carbonisation of PAN fibres was investigated by thermal analyses methods. Moreover, electrospun PAN/CTP fibres were carbonised at two different temperatures i.e., 850 °C and 1200 °C and their crystallographic structures of resulting such low-cost PAN/CTP CFs were studied through X-ray diffraction (XRD) and Raman analyses. Compared to pure PAN CFs, the electrical resistivity of PAN/25% CTP CFs significantly decreased by 92%, reaching 1.6 kΩ/sq. The overall results showed that PAN precursor containing 25% CTP resulted in balanced properties in terms of spinnability, thermal and structural properties. It is believed that CTP has a great potential to be used as an additive for PAN precursor and will pave the way for cost-reduced and high-performance CFs.

Quantitative pediatric vision screening in primary care settings in Alabama.

PURPOSE: Alabama Medicaid reimburses "objective" vision screening (VS), i.e., by acuity or similar quantitative method, and well child checks (WCCs) separately. We analyzed the frequency of each service obtained. METHODS: Claims for WCC and VS provided between October 1, 2002 and September 30, 2003 for children aged 3 to 18 years, and summary data for all enrolled children, were obtained from Alabama Medicaid. We used univariate analysis followed by logistic regression to explore the potential influence of factors (patient age, provider type, and provider's volume of WCCs) on the receipt of VS at pre-school ages. RESULTS: Children receiving WCCs were 55% black, 40% white, and 5% other. Percentages of children with WCC claims were highest at 4 years (57%) and thereafter declined to 30% at 6 to 14 years and to <10% at 18 years. Nearly all VS (>98% at each age) occurred the same day as the WCC. Pediatricians provided 68% of all WCCs. Multivariate analysis, after adjusting for nesting of pre-school patients within provider, showed the odds ratios (ORs) of VS were increased by patient age (5 years vs. 3 years, OR = 3.57, p < 0.0001), nonphysician provider type (nonphysician vs. pediatrician, OR = 1.80, p = 0.0004) and high WCC volume (at or above vs. below the median number (n = 8) of WCC per provider per year (OR = 7.11, p < 0.0001)). Because VS rates were high when attendance to WCC visits was low, few enrolled children received VS at any age (6% at the age of 3, 13% at the age of 4, and a maximum of 20% at the age of 5). CONCLUSIONS: National efforts to reduce preventable vision loss from amblyopia are hampered because children are not available for screening and because providers miss many opportunities to screen vision at pre-school age. Efforts to improve VS should target pediatrician-led practices, because these serve greater numbers of children.

Dataset for the estimation of costs for direct contact condenser.

The dataset on equations and procedures for the estimation of detailed capital and annual costs for direct contact condenser are presented. Full dataset on four design cases relevant to the comparisons on the costs of air and oxy-fuel direct contact condenser is given. The data are presented in this format to allow the comparison with those from other researchers in this field. The data presented are related to the article entitled "A comparative study on the design of direct contact condenser for air and oxy-fuel combustion flue gas based on Callide Oxy-fuel Project" (Liu et al., 2018) [1].

Ethics in the Legal and Business Practices of Radiation Oncology.

Ethical issues arise when a professional endeavor such as medicine, which seeks to place the well-being of others over the self-interest of the practitioner, meets granular business and legal decisions involved in making a livelihood out of a professional calling. The use of restrictive covenants, involvement in self-referral patterns, and maintaining appropriate comity among physicians while engaged in the marketplace are common challenges in radiation oncology practice. A paradigm of analysis is presented to help navigate these management challenges.

Improving Inpatient Asthma Management: The Implementation and Evaluation of a Pediatric Asthma Clinical Pathway.

INTRODUCTION: Asthma exacerbations are a leading cause of pediatric hospitalizations. Despite national guidelines, variability exists in the use and dosing of bronchodilators, oxygen management, and respiratory assessments of patients. We aimed to implement an inpatient Asthma Clinical Pathway (Pathway) to standardize care and reduce length of stay (LOS). METHODS: A respiratory therapy-driven Pathway was designed for inpatient asthma management. The Pathway included standardized respiratory therapy assessments, bronchodilator dosing, and protocols for progression and clinical worsening. We monitored key process measures. Patients admitted to the Pathway during pilot implementation (March to December 2011) were compared retrospectively with a "Usual Care" cohort admitted during the same period. We compared average LOS, average billed charges per hospitalization (charges), and 30-day readmissions between groups. Statistical process control charts were utilized to analyze LOS and charges for all asthma admissions following Pathway implementation (March 2011 to September 2016). Readmissions and Pathway removals were balancing measures. RESULTS: During pilot, Pathway patients (n = 153) compared with "Usual Care" patients (n = 166) had shorter LOS (0.95 versus 1.86 days; P < 0.001) and lower charges ($7,413 versus $11,078; P < 0.001). Readmission rates were not significantly different between groups. LOS for all asthma admissions (n = 3,429) decreased from 2.30 to 1.44 days (P < 0.001) following Pathway implementation. Charges remained stable. The readmission rate (per 100 discharges) for all asthma was 2.42 and not significantly different between Pathway and non-Pathway groups. CONCLUSIONS: Pathway implementation reduced LOS and stabilized charges while not increasing readmission rates. The Pathway facilitated sustainable widely adopted improvements in asthma care.

Measuring resident physicians' performance of preventive care. Comparing chart review with patient survey.

BACKGROUND: The Accreditation Council for Graduate Medical Education has suggested various methods for evaluation of practice-based learning and improvement competency, but data on implementation of these methods are limited. OBJECTIVE: To compare medical record review and patient surveys on evaluating physician performance in preventive services in an outpatient resident clinic. DESIGN: Within an ongoing quality improvement project, we collected baseline performance data on preventive services provided for patients at the University of Alabama at Birmingham (UAB) Internal Medicine Residents' ambulatory clinic. PARTICIPANTS: Seventy internal medicine and medicine-pediatrics residents from the UAB Internal Medicine Residency program. MEASUREMENTS: Resident- and clinic-level comparisons of aggregated patient survey and chart documentation rates of (1) screening for smoking status, (2) advising smokers to quit, (3) cholesterol screening, (4) mammography screening, and (5) pneumonia vaccination. RESULTS: Six hundred and fifty-nine patient surveys and 761 charts were abstracted. At the clinic level, rates for screening of smoking status, recommending mammogram, and for cholesterol screening were similar (difference <5%) between the 2 methods. Higher rates for pneumonia vaccination (76% vs 67%) and advice to quit smoking (66% vs 52%) were seen on medical record review versus patient surveys. However, within-resident (N=70) comparison of 2 methods of estimating screening rates contained significant variability. The cost of medical record review was substantially higher ($107 vs $17/physician). CONCLUSIONS: Medical record review and patient surveys provided similar rates for selected preventive health measures at the clinic level, with the exception of pneumonia vaccination and advising to quit smoking. A large variation among individual resident providers was noted.

Implementing achievable benchmarks in preventive health: a controlled trial in residency education.

PURPOSE: To evaluate the Preventive Health Achievable Benchmarks Curriculum, a multifaceted improvement intervention that included an objective, practice-based performance evaluation of internal medicine and pediatric residents' delivery of preventive services. METHOD: The authors conducted a nonrandomized experiment of intervention versus control group residents with baseline and follow-up of performance audited for 2001-2004. All 130 internal medicine and 78 pediatric residents at two continuity clinics at the University of Alabama School of Medicine, Birmingham, participated. Performance of preventive care was assessed by structured chart review. The multifaceted feedback curriculum included individualized performance feedback, academic detailing by faculty, and collective didactic sessions. The main outcome was difference in receipt of preventive care for patients seen by intervention and control residents, comparing baseline and follow-up. RESULTS: Charts were reviewed for 3,958 patients. Receipt of preventive care increased for patients of intervention residents, but not for patients of control residents. For the intervention group, significant increases occurred for five of six indicators in internal medicine: smoking screening, quit smoking advice, colon cancer screening, pneumonia vaccine, and lipid screening; and four of six in pediatrics: parental quit smoking advice, car seats, car restraints, and eye alignment (p < .05 for all). For control residents, no consistent improvements were seen. There was greater improvement for intervention than for control residents for four of six indicators in internal medicine, and two of six in pediatrics. CONCLUSIONS: Using a multifaceted feedback curriculum, the authors taught residents about the care they provide and improved documented patient care.

Hearing screening practices among a national sample of primary care pediatricians.

The objective of this study was to describe variations in hearing screening using a survey mailed to a national sample of primary care pediatricians prior to the 2003 American Academy of Pediatrics (AAP) hearing screening guidelines. Of the 390 primary care respondents, only 303 (78%) performed audiometry, routinely beginning at age 3 (32%), 4 (44%), or 5 (17%); 81% defined abnormal audiometry primarily as failure to hear at a specified decibel level: 15 dB hearing level (HL) (<1%), 16 to 20 dB HL (10%), 21 to 25 dB HL (23%), 26 to 30 dB HL (44%), 31 to 40 dB HL (16%), and more than 40 dB HL (6%). This study serves as a baseline for comparison with postguideline practices.

Differences in preventive health quality by residency year. Is seniority better?

BACKGROUND: It is assumed that the performance of more senior residents is superior to that of interns, but this has not been assessed objectively. OBJECTIVE: To determine whether adherence to national guidelines for outpatient preventive health services differs by year of residency training. DESIGN: Cross-sectional study. PARTICIPANTS: One hundred twenty Internal Medicine residents, postgraduate year (PGY)- 1 and PGY -2, attending a University Internal Medicine teaching clinic between June 2000 and May 2003. MEASUREMENTS: We studied 6 preventive health care services offered or received by patients by abstracting data from 1,017 patient records. We examined the differences in performance between PGY-1 and PGY-2 residents. RESULTS: Postgraduate year-2 residents did not statistically outperform PGY-1 residents on any measure. The overall proportion of patients receiving appropriate preventive health services for pneumococcal vaccination, advising tobacco cessation, breast and colon cancer screening, and lipid screening was similar across levels of training. PGY-1s outperformed PGY-2s for tobacco use screening (58%, 51%, P = .03). These results were consistent after accounting for clustering of patients within provider and adjusting for patient age, gender, race and insurance, resident gender, and number of visits during the measurement year. CONCLUSIONS: Overall, patients cared for by PGY-2 residents did not receive more outpatient preventive health services than those cared for by PGY-1 residents. Efforts should be made to ensure quality patient care in the outpatient setting for all levels of training.

Hearing screening at well-child visits.

OBJECTIVES: To determine hearing screening failure rates in primary care settings and to examine the referral practices in response to an abnormal screening test. METHODS: We enrolled a convenience sample of children between 3 and 19 years of age who were undergoing hearing screening during a well-child visit. A failure was defined as missing any frequency (1000, 2000, or 4000 Hz) in either ear at 20-dB hearing level. The pediatrician made the decision of whether to refer the patient for further evaluation. RESULTS: Three academic and 5 private practices enrolled 1061 children. Sixty-seven children (7%) were unable to complete the screening. Of the 948 children who completed the screen, a total of 852 children (90%) passed the screening and 96 children (10%) failed. After multivariable logistic regression analysis, the only statistically significant factor predictive of a failed screen was developmental delay (P = .02). Of the 96 children who failed the hearing screening, 57 (59%) had no further evaluation, 12 (13%) were rechecked, and 27 (28%) were referred. Similar percentages were seen with children who could not be screened. CONCLUSIONS: Although 10% of the children failed hearing screening, pediatricians neither rechecked nor referred more than half of these children. Screening that does not result in action for those failing the screening wastes resources and fails to properly identify hearing impairment in children.

Multicomponent Internet continuing medical education to promote chlamydia screening.

BACKGROUND: Low Chlamydia trachomatis screening rates create an opportunity to test innovative continuing medical education (CME) programs. Few studies of Internet-based physician learning have been evaluated with objective data on practice patterns. DESIGN: This randomized controlled trial tested a multicomponent Internet CME (mCME) intervention for increasing chlamydia screening of at-risk women aged 16 to 26 years. SETTING: Eligible physician offices had > or =20 patients at risk for chlamydia as defined by the Health Plan Employer Data and Information Set (HEDIS), had at least one primary care physician (internal medicine, family medicine/general practice, pediatrics) with Internet access, and participated in the study managed care organization. The 191 randomized primary care offices represented 20 states. INTERVENTION: The intervention, available from February to December 2001, consisted of four case-based learning modules, was tailored in real time to each physician based on theory of behavior change, and included office-level feedback of chlamydia screening rates. MAIN OUTCOME MEASURE: HEDIS chlamydia screening rates for the pre-intervention (2000) and post-intervention (2002) periods. RESULTS: Pre-intervention screening rates for the intervention and comparison offices were 18.9% and 16.2% (p =0.135). Post-intervention screening rates for the intervention and comparison offices were 15.5% and 12.4%, respectively (p =0.044, adjusting for baseline performance). CONCLUSIONS: The substantial decline in chlamydia screening rates observed in the comparison offices was significantly attenuated for the intervention offices. The mCME favorably influenced chlamydia screening by primary care physicians.

Improving physician performance through Internet-based interventions: who will participate?

BACKGROUND: The availability of Internet-based continuing medical education is rapidly increasing, but little is known about recruitment of physicians to these interventions. OBJECTIVE: The purpose of this study was to examine predictors of physician participation in an Internet intervention designed to increase screening of young women at risk for chlamydiosis. METHODS: Eligibility was based on administrative claims data, and eligible physicians received recruitment letters via fax and/or courier. Recruited offices had at least one physician who agreed to participate in the study by providing an email address. After one physician from an office was recruited, intensive recruitment of that office ceased. Email messages reminded individual physicians to participate by logging on to the Internet site. RESULTS: Of the eligible offices, 325 (33.2%) were recruited, from which 207 physicians (52.8%) participated. Recruited versus nonrecruited offices had more eligible patients (mean number of eligible patients per office: 44.1 vs 33.6; P < .001), more eligible physicians (mean number of eligible physicians per office: 6.2 vs 4.1; P < .001), and fewer doctors of osteopathy (mean percent of eligible physicians per office who were doctors of osteopathy: 20.5% vs 26.4%; P = .02). Multivariable analysis revealed that the odds of recruiting at least one physician from an office were greater if the office had more eligible patients and more eligible physicians. More participating versus nonparticipating physicians were female (mean percent of female recruited physicians: 39.1% vs 27.0%; P = .01); fewer participating physicians were doctors of osteopathy (mean percent of recruited physicians who were doctors of osteopathy: 15.5% vs 23.9%; P = .04) or international medical graduates (mean percent of recruited physicians who were international graduates: 12.3% vs 23.8%; P = .003). Multivariable analysis revealed that the odds of a physician participating were greater if the physician was older than 55 years (OR = 2.31; 95% CI = 1.09-4.93) and was from an office with a higher Chlamydia screening rate in the upper tertile (OR = 2.26; 95% CI = 1.23-4.16). CONCLUSIONS: Physician participation in an Internet continuing medical education intervention varied significantly by physician and office characteristics.

Identifying physician-recognized depression from administrative data: consequences for quality measurement.

BACKGROUND: Multiple factors limit identification of patients with depression from administrative data. However, administrative data drives many quality measurement systems, including the Health Plan Employer Data and Information Set (HEDIS). METHODS: We investigated two algorithms for identification of physician-recognized depression. The study sample was drawn from primary care physician member panels of a large managed care organization. All members were continuously enrolled between January 1 and December 31, 1997. Algorithm 1 required at least two criteria in any combination: (1) an outpatient diagnosis of depression or (2) a pharmacy claim for an antidepressant Algorithm 2 included the same criteria as algorithm 1, but required a diagnosis of depression for all patients. With algorithm 1, we identified the medical records of a stratified, random subset of patients with and without depression (n = 465). We also identified patients of primary care physicians with a minimum of 10 depressed members by algorithm 1 (n = 32,819) and algorithm 2 (n = 6,837). RESULTS: The sensitivity, specificity, and positive predictive values were: Algorithm 1: 95 percent, 65 percent, 49 percent; Algorithm 2: 52 percent, 88 percent, 60 percent. Compared to algorithm 1, profiles from algorithm 2 revealed higher rates of follow-up visits (43 percent, 55 percent) and appropriate antidepressant dosage acutely (82 percent, 90 percent) and chronically (83 percent, 91 percent) (p < 0.05 for all). CONCLUSIONS: Both algorithms had high false positive rates. Denominator construction (algorithm 1 versus 2) contributed significantly to variability in measured quality. Our findings raise concern about interpreting depression quality reports based upon administrative data.
