Global evidence of gender equity in academic health research: a scoping review.

OBJECTIVES: To chart the global literature on gender equity in academic health research. DESIGN: Scoping review. PARTICIPANTS: Quantitative studies were eligible if they examined gender equity within academic institutions including health researchers. PRIMARY AND SECONDARY OUTCOME MEASURES: Outcomes related to equity across gender and other social identities in academia: (1) faculty workforce: representation of all genders in university/faculty departments, academic rank or position and salary; (2) service: teaching obligations and administrative/non-teaching activities; (3) recruitment and hiring data: number of applicants by gender, interviews and new hires for various rank; (4) promotion: opportunities for promotion and time to progress through academic ranks; (5) academic leadership: type of leadership positions, opportunities for leadership promotion or training, opportunities to supervise/mentor and support for leadership bids; (6) scholarly output or productivity: number/type of publications and presentations, position of authorship, number/value of grants or awards and intellectual property ownership; (7) contextual factors of universities; (8) infrastructure; (9) knowledge and technology translation activities; (10) availability of maternity/paternity/parental/family leave; (11) collaboration activities/opportunities for collaboration; (12) qualitative considerations: perceptions around promotion, finances and support. RESULTS: Literature search yielded 94 798 citations; 4753 full-text articles were screened, and 562 studies were included. Most studies originated from North America (462/562, 82.2%). Few studies (27/562, 4.8%) reported race and fewer reported sex/gender (which were used interchangeably in most studies) other than male/female (11/562, 2.0%). Only one study provided data on religion. No other PROGRESS-PLUS variables were reported. A total of 2996 outcomes were reported, with most studies examining academic output (371/562, 66.0%). CONCLUSIONS: Reviewed literature suggest a lack in analytic approaches that consider genders beyond the binary categories of man and woman, additional social identities (race, religion, social capital and disability) and an intersectionality lens examining the interconnection of multiple social identities in understanding discrimination and disadvantage. All of these are necessary to tailor strategies that promote gender equity. TRIAL REGISTRATION NUMBER: Open Science Framework: https://osf.io/8wk7e/.

Wage losses among spouses of women with nonmetastatic breast cancer.

BACKGROUND: The aim of this study was to evaluate the wage losses incurred by spouses of women with nonmetastatic breast cancer in the 6 months after the diagnosis. METHODS: A prospective cohort study of spouses of women diagnosed with nonmetastatic breast cancer who were recruited in 8 hospitals in the province of Quebec (Canada) was performed. Information for estimating wage losses was collected by telephone interviews conducted 1 and 6 months after the diagnosis. Log-binomial regressions were used to identify personal, medical, and employment characteristics associated with experiencing wage losses, and generalized linear models were used to identify characteristics associated with the proportion of usual wages lost. RESULTS: Overall, 829 women (86% participation) and 406 spouses (75% participation) consented to participate. Among the 279 employed spouses, 78.5% experienced work absences because of breast cancer. Spouses were compensated for 66.3% of their salary on average during their absence. The median wage loss was $0 (mean, $1820) (2003 Canadian dollars). Spouses were more likely to experience losses if they were self-employed or lived 50 km or farther from the hospital. Among spouses who experienced wage losses, those who were self-employed or whose partners had invasive breast cancer lost a higher proportion of wages. CONCLUSIONS: Although spouses took some time off work, for many, the resulting wage losses were modest because of compensation received. Still, the types of compensation used may hide other forms of burden for families facing breast cancer.

Health system costs of potentially inappropriate prescribing in Ontario, Canada: a protocol for a population-based cohort study.

INTRODUCTION: Adverse drug events (ADEs) are common in older persons and contribute significantly to emergency department visits, hospitalisations and mortality. ADEs are often due to potentially inappropriate prescriptions (PIP) or potentially inappropriate omissions (PIO), and are avoidable if inappropriate prescriptions or omissions are identified and prevented. Identifying PIP/PIO at the population level through the application of PIP/PIO assessment tools to health administrative data can provide a unique opportunity to assess the economic burden of PIP/PIO on the healthcare system beyond medication costs which is yet to be done. The objective of this study is to assess the economic burden associated with PIP/PIO and to estimate the incremental costs associated with distinct PIP/PIO in the province of Ontario. METHODS AND ANALYSIS: We will conduct a retrospective cohort study using Ontario's health administrative databases. Eligible patients aged 66 years and older who were prescribed at least one medication between 1 April 2003 and 31 March 2014 (approximately 2.4 million patients) will be included. Population attributable fraction methodology will be used to assess the overall burden of PIP in Ontario, while regression analyses will be used to estimate the incremental costs of having specific PIP criteria and aid in prioritising targets for intervention. ETHICS AND DISSEMINATION: This study was approved by the Institutional Review Board at Sunnybrook Health Sciences Centre, Toronto, Canada. Dissemination will occur via publication, presentation at national and international conferences, and knowledge exchange with various stakeholders.

Cost effectiveness of the addition of a comprehensive CT scan to the abdomen and pelvis for the detection of cancer after unprovoked venous thromboembolism.

IMPORTANCE: Unprovoked venous thromboembolism (VTE) can be the first manifestation of cancer. It is unclear if extensive screening for occult cancer including a comprehensive computed tomography (CT) scan of the abdomen/pelvis is cost-effective in this patient population. OBJECTIVE: To assess the health care related costs, number of missed cancer cases and health related utility values of a limited screening strategy with and without the addition of a comprehensive CT scan of the abdomen/pelvis and to identify to what extent testing should be done in these circumstances to allow early detection of occult cancers. PARTICIPANTS AND SETTING: Cost effectiveness analysis using data that was collected alongside the SOME randomized controlled trial which compared an extensive occult cancer screening including a CT of the abdomen/pelvis to a more limited screening strategy in patients with a first unprovoked VTE, was used for the current analyses. MAIN OUTCOMES AND MEASURES: Analyses were conducted with a one-year time horizon from a Canadian health care perspective. Primary analysis was based on complete cases, with sensitivity analysis using appropriate multiple imputation methods to account for missing data. RESULTS: Data from a total of 854 patients with a first unprovoked VTE were included in these analyses. The addition of a comprehensive CT scan was associated with higher costs ($551 CDN) with no improvement in utility values or number of missed cancers. Results were consistent when adopting multiple imputation methods. CONCLUSIONS AND RELEVANCE: The addition of a comprehensive CT scan of the abdomen/pelvis for the screening of occult cancer in patients with unprovoked VTE is not cost effective, as it is both more costly and not more effective in detecting occult cancer.

Effectiveness of a hospital-initiated smoking cessation programme: 2-year health and healthcare outcomes.

BACKGROUND: Tobacco-related illnesses are leading causes of death and healthcare use. Our objective was to determine whether implementation of a hospital-initiated smoking cessation intervention would reduce mortality and downstream healthcare usage. METHODS: A 2-group effectiveness study was completed comparing patients who received the 'Ottawa Model' for Smoking Cessation intervention (n=726) to usual care controls (n=641). Participants were current smokers, >17 years old, and recruited during admission to 1 of 14 participating hospitals in Ontario, Canada. Baseline data were linked to healthcare administrative data. Competing-risks regression analysis was used to compare outcomes between groups. RESULTS: The intervention group experienced significantly lower rates of all-cause readmissions, smoking-related readmissions, and all-cause emergency department (ED) visits at all time points. The largest absolute risk reductions (ARR) were observed for all-cause readmissions at 30 days (13.3% vs 7.1%; ARR, 6.1% (2.9% to 9.3%); p<0.001), 1 year (38.4% vs 26.7%; ARR, 11.7% (6.7% to 16.6%); p<0.001), and 2 years (45.2% vs 33.6%; ARR, 11.6% (6.5% to 16.8%); p<0.001). The greatest reduction in risk of all-cause ED visits was at 30 days (20.9% vs 16.4%; ARR, 4.5% (0.4% to 8.7%); p=0.03). Reduction in mortality was not evident at 30 days, but significant reductions were observed by year 1 (11.4% vs 5.4%; ARR 6.0% (3.1% to 9.0%); p<0.001) and year 2 (15.1% vs 7.9%; ARR, 7.3% (3.9% to 10.7%); p<0.001). CONCLUSIONS: Considering the relatively low cost, greater adoption of hospital-initiated tobacco cessation interventions should be considered to improve patient outcomes and decrease subsequent healthcare usage.

Communication Development in Early-Identified Children With Mild Bilateral and Unilateral Hearing Loss.

PURPOSE: This clinical focus article provides preliminary findings from a multicenter longitudinal study investigating auditory and communication development in children with mild bilateral or unilateral hearing loss of any degree. METHOD: A total of 100 children (55 with mild bilateral or unilateral hearing loss and 45 with normal hearing) underwent 1 or more assessments from a battery of auditory and language measures. RESULTS: Children up to age 4 years demonstrated auditory and language skills similar to those of children with normal hearing. CONCLUSIONS: Factors that affect outcomes in communication development will be explored as additional data are collected in this ongoing study.

Economic evaluation of a hospital-initiated intervention for smokers with chronic disease, in Ontario, Canada.

INTRODUCTION: Cigarette smoking causes many chronic diseases that are costly and result in frequent hospitalisation. Hospital-initiated smoking cessation interventions increase the likelihood that patients will become smoke-free. We modelled the cost-effectiveness of the Ottawa Model for Smoking Cessation (OMSC), an intervention that includes in-hospital counselling, pharmacotherapy and posthospital follow-up, compared to usual care among smokers hospitalised with acute myocardial infarction (AMI), unstable angina (UA), heart failure (HF), and chronic obstructive pulmonary disease (COPD). METHODS: We completed a cost-effectiveness analysis based on a decision-analytic model to assess smokers hospitalised in Ontario, Canada for AMI, UA, HF, and COPD, their risk of continuing to smoke and the effects of quitting on re-hospitalisation and mortality over a 1-year period. We calculated short-term and long-term cost-effectiveness ratios. Our primary outcome was 1-year cost per quality-adjusted life year (QALY) gained. RESULTS: From the hospital payer's perspective, delivery of the OMSC can be considered cost effective with 1-year cost per QALY gained of $C1386, and lifetime cost per QALY gained of $C68. In the first year, we calculated that provision of the OMSC to 15 326 smokers would generate 4689 quitters, and would prevent 116 rehospitalisations, 923 hospital days, and 119 deaths. Results were robust within numerous sensitivity analyses. DISCUSSION: The OMSC appears to be cost-effective from the hospital payer perspective. Important consideration is the relatively low intervention cost compared to the reduction in costs related to readmissions for illnesses associated with continued smoking.

Validity of standard gamble estimated quality of life in acute venous thrombosis.

INTRODUCTION: The standard gamble is considered the 'gold standard' technique for measuring quality of life. We recently used the standard gamble to estimate quality of life in acute venous thrombosis, and found unexpected variability in the responses. The current study aimed to explore the reasons for variability by comparing the standard gamble technique in patients with acute venous thrombosis to other quality of life measurement tools. MATERIALS AND METHODS: Thrombosis clinic patients treated for venous thrombosis were eligible to participate. Patients evaluated their current health state by performing a standard gamble interview, reporting on a visual analogue scale, completing the SF-36 and disease specific questionnaires (PEmb-Qol and VEINES-QOL/Sym). Validity was assessed by correlating the standard gamble utilities with the other methods. Test-retest reliability, responsiveness and acceptability were also assessed. RESULTS: Forty-four patients were interviewed, with 16 attending for a repeat interview. The median standard gamble utility was 0.97 (0.84-1.0), SF-6D 0.64 (0.59 - 0.80) and visual analogue score 70 (60 - 80). Participants with pulmonary embolism had lower standard gamble estimates than those with deep vein thrombosis. There was good discriminant validity in that the standard gamble estimates were not associated with risk taking behavior, negative outlook, sex or education. Test-retest reliability with the standard gamble was moderate and there was evidence of a ceiling effect. CONCLUSIONS: Standard gamble utilities are higher than other methods of measuring quality of life in venous thrombosis. The choice of utility values adopted in studies will impact on future economic studies.

Estimating quality of life in acute venous thrombosis.

IMPORTANCE: Future funding for new treatments in venous thromboembolism will be guided by cost-utility analyses. There is little available information on the utility of acute venous thromboembolism, limiting the validity of economic analyses. OBJECTIVE: To measure the quality of life in the health states relating to thromboembolism cost-utility analyses. DESIGN: A prospective cohort study. SETTING: A single-center, university-affiliated thrombosis clinic. PARTICIPANTS: Two hundred sixteen thrombosis clinic patients with a history of lower limb deep vein thrombosis (DVT) or pulmonary embolism (PE). EXPOSURES: Participants consented to take a standard gamble interview. Each participant rated the quality of life in acute DVT, acute PE, and bleeding complication health states. MAIN OUTCOMES AND MEASURES: The standard gamble measured quality of life (utility value) for acute DVT, acute PE, major intracranial bleeding event, minor intracranial bleeding event, and gastrointestinal bleeding event. RESULTS: Two hundred fifteen responses were included in the analysis. Twenty-six percent had experienced both PE and DVT; 54%, DVT alone; and 20%, PE alone. Forty-two percent had experienced more than 1 episode of thrombosis, and 23% had had cancer-associated thrombosis. We found the median utility for acute DVT was 0.81 (interquartile range [IQR], 0.55-0.94); acute PE, 0.75 (IQR, 0.45-0.91); major intracranial bleeding event, 0.15 (IQR, 0.00-0.65); minor intracranial bleeding event, 0.75 (IQR, 0.55-0.92); and gastrointestinal bleeding event, 0.65 (IQR, 0.15-0.86). The median length of symptoms for DVT or PE was 1 week (IQR, <1-3 weeks). CONCLUSIONS AND RELEVANCE: To our knowledge, this is the largest published study on utilities in which the participants had personal experience of venous thromboembolism. We present unique information for economic analyses but have also identified future challenges for research in this area. Our summary results differ from those previously published, and we found wide variation in individual responses.

Out-of-pocket costs in the year after early breast cancer among Canadian women and spouses.

BACKGROUND: We lack comprehensive information about the extent of out-of-pocket costs after diagnosis of early breast cancer and their effects on the family's financial situation. METHODS: This longitudinal study assessed out-of-pocket costs and wage losses during the first year after diagnosis of early breast cancer among Canadian women and spouses. Out-of-pocket costs for treatments and follow-up, consultations with other practitioners, home help, clothing, and natural health products were estimated, with information collected from telephone interviews. Generalized linear models were used to identify women at risk of having higher costs and the effects of out-of-pocket costs on perceptions of the family's financial situation. RESULTS: Overall, 829 women (participation, 86.2%) and 391 spouses participated. Women's median net out-of-pocket costs during the year after diagnosis were $1002 (2003 Canadian dollars; mean = $1365; SD = $1238), and 74.4% of these costs resulted from treatments and follow-up. Spouses' median costs were $111 (mean = $234; SD = $320), or 9% of couples' total expenses. In multivariable analyses, the percentage of women with out-of-pocket costs of $1773 or more (upper quartile) was statistically significantly associated with higher education, working at diagnosis, living more than 50 km from the hospital where surgery was performed, and having two and three different types of adjuvant treatment (all 2-sided P values ≤ .01). However, when considered simultaneously with wage losses, out-of-pocket costs were not associated with perceived deterioration in the family's financial situation; rather, wage losses were the driving factor. CONCLUSIONS: Overall, out-of-pocket costs from breast cancer for the year after diagnosis are probably not unmanageable for most women. However, some women were at higher risk of experiencing financial burden resulting from these costs.

Ottawa panel evidence-based clinical practice guidelines for aerobic walking programs in the management of osteoarthritis.

OBJECTIVE: To update the Evidence-Based Clinical Practice Guidelines (EBCPGs) on aerobic walking programs for the management of osteoarthritis (OA) of the knee. DATA SOURCES: A literature search was conducted using the electronic databases MEDLINE, PubMed, and the Cochrane Library for all studies related to aerobic walking programs for OA from 1966 until February 2011. STUDY SELECTION: The literature search found 719 potential records, and 10 full-text articles were included according to the selection criteria. The Ottawa Methods Group established the inclusion and exclusion criteria regarding the characteristics of the population, by selecting adults of 40 years old and older who were diagnosed with OA of the knee. DATA EXTRACTION: Two reviewers independently extracted important information from each selected study using standardized data extraction forms, such as the interventions, comparisons, outcomes, time period of the effect measured, and study design. The statistical analysis was reported using the Cochrane collaboration methods. An improvement of 15% or more relative to a control group contributes to the achievement of a statistically significant and clinically relevant progress. A specific grading system for recommendations, created by the Ottawa Panel, used a level system (level I for randomized controlled studies and level II for nonrandomized articles). The strength of the evidence of the recommendations was graded using a system with letters: A, B, C+, C, D, D+, or D-. DATA SYNTHESIS: Evidence from 7 high-quality studies demonstrated that facility, hospital, and home-based aerobic walking programs with other therapies are effective interventions in the shorter term for the management of patients with OA to improve stiffness, strength, mobility, and endurance. CONCLUSIONS: The greatest improvements were found in pain, quality of life, and functional status (grades A, B, or C+). A common limitation inherent to the EBCPGs is the heterogeneity of studies included with regards to the characteristics of the population, the interventions, the comparators, the outcomes, the period of time, and the study design. It is strongly recommended to use the Cochrane Risk of Bias Summary assessment to evaluate the methodologic quality of the studies and to consider avenues for future research on how aerobic walking programs would be beneficial in the management of OA of the hip.

Comparing multiple competing interventions in the absence of randomized trials using clinical risk-benefit analysis.

BACKGROUND: To demonstrate the use of risk-benefit analysis for comparing multiple competing interventions in the absence of randomized trials, we applied this approach to the evaluation of five anticoagulants to prevent thrombosis in patients undergoing orthopedic surgery. METHODS: Using a cost-effectiveness approach from a clinical perspective (i.e. risk benefit analysis) we compared thromboprophylaxis with warfarin, low molecular weight heparin, unfractionated heparin, fondaparinux or ximelagatran in patients undergoing major orthopedic surgery, with sub-analyses according to surgery type. Proportions and variances of events defining risk (major bleeding) and benefit (thrombosis averted) were obtained through a meta-analysis and used to define beta distributions. Monte Carlo simulations were conducted and used to calculate incremental risks, benefits, and risk-benefit ratios. Finally, net clinical benefit was calculated for all replications across a range of risk-benefit acceptability thresholds, with a reference range obtained by estimating the case fatality rate - ratio of thrombosis to bleeding. RESULTS: The analysis showed that compared to placebo ximelagatran was superior to other options but final results were influenced by type of surgery, since ximelagatran was superior in total knee replacement but not in total hip replacement. CONCLUSIONS: Using simulation and economic techniques we demonstrate a method that allows comparing multiple competing interventions in the absence of randomized trials with multiple arms by determining the option with the best risk-benefit profile. It can be helpful in clinical decision making since it incorporates risk, benefit, and personal risk acceptance.

Evaluating survivorship care plans: results of a randomized, clinical trial of patients with breast cancer.

PURPOSE: An Institute of Medicine report recommends that patients with cancer receive a survivorship care plan (SCP). The trial objective was to determine if an SCP for breast cancer survivors improves patient-reported outcomes. PATIENTS AND METHODS: Women with early-stage breast cancer who completed primary treatment at least 3 months previously were eligible. Consenting patients were allocated within two strata: less than 24 months and ≥ 24 months since diagnosis. All patients were transferred to their own primary care physician (PCP) for follow-up. In addition to a discharge visit, the intervention group received an SCP, which was reviewed during a 30-minute educational session with a nurse, and their PCP received the SCP and guideline on follow-up. The primary outcome was cancer-related distress at 12 months, assessed by the Impact of Event Scale (IES). Secondary outcomes included quality of life, patient satisfaction, continuity/coordination of care, and health service measures. RESULTS: Overall, 408 survivors were enrolled through nine tertiary cancer centers. There were no differences between groups on cancer-related distress or on any of the patient-reported secondary outcomes, and there were no differences when the two strata were analyzed separately. More patients in the intervention than control group correctly identify their PCP as primarily responsible for follow-up (98.7% v 89.1%; difference, 9.6%; 95% CI, 3.9 to 15.9; P = .005). CONCLUSION: The results do not support the hypothesis that SCPs are beneficial for improving patient-reported outcomes. Transferring follow-up to PCPs is considered an important strategy to meet the demand for scarce oncology resources. SCPs were no better than a standard discharge visit with the oncologist to facilitate transfer.

Out-of-pocket costs for accessing adjuvant radiotherapy among Canadian women with breast cancer.

PURPOSE: Patients with breast cancer incur out-of-pocket costs when they receive adjuvant radiation. These treatments are administered in dedicated centers on a daily basis over 4 to 5 weeks. We assessed the extent of out-of-pocket costs to access radiotherapy and identified women at risk of experiencing higher costs. PATIENTS AND METHODS: This prospective study was conducted among 800 women from eight Quebec hospitals (participation, 86%), of whom 693 women received adjuvant radiotherapy. Costs to access treatment (transportation, parking, lodging, and meals) were estimated on the basis of information collected by telephone interviews. Generalized linear models were used to identify women at risk of having higher costs. RESULTS: Mean and median total costs (including financial aid received) to access radiotherapy were 445 Canadian dollars (Can$; standard deviation, Can$407) and Can$311, respectively. Women who lived at home but far from the radiotherapy center had the highest risk of experiencing weekly costs of at least Can$122 (highest quartile; prevalence ratio [PR], 5.8; 95% CI, 4.7 to 7.1) followed by women who lived away from home and farther from the center (PR, 4.5; 95% CI, 3.4 to 6.0) and by women who lived away from home and closer to the center (PR, 2.14; 95% CI, 1.3 to 3.5). When women stayed at a cancer lodge during treatment, costs were reduced by 80%. CONCLUSION: Considered in and of themselves, out-of-pocket costs for access to radiotherapy appeared relatively modest. Financial assistance initiatives for women who lived away from home during treatments contributed to a substantial reduction of access costs. These efforts should be maintained, but financial assistance should also target patients with cancer who live at home during treatments but have to travel relatively long distances on a daily basis.

(Correcting) misdiagnoses of asthma: a cost effectiveness analysis.

BACKGROUND: The prevalence of physician-diagnosed-asthma has risen over the past three decades and misdiagnosis of asthma is potentially common. OBJECTIVE: to determine whether a secondary-screening-program to establish a correct diagnosis of asthma in those who report a physician diagnosis of asthma is cost effective. METHOD: Randomly selected physician-diagnosed-asthmatic subjects from 8 Canadian cities were studied with an extensive diagnostic algorithm to rule-in, or rule-out, a correct diagnosis of asthma. Subjects in whom the diagnosis of asthma was excluded were followed up for 6-months and data on asthma medications and heath care utilization was obtained. Economic analysis was performed to estimate the incremental lifetime costs associated with secondary screening of previously diagnosed asthmatic subjects. Analysis was from the perspective of the Canadian healthcare system and is reported in Canadian dollars. RESULTS: Of 540 randomly selected patients with physician diagnosed asthma 150 (28%; 95%CI 19-37%) did not have asthma when objectively studied. 71% of these misdiagnosed patients were on some asthma medications. Incorporating the incremental cost of secondary-screening for the diagnosis of asthma, we found that the average cost savings per 100 individuals screened was $35,141 (95%CI $4,588-$69,278). CONCLUSION: Cost savings primarily resulted from lifetime costs of medication use averted in those who had been misdiagnosed.

Cost-effectiveness of epinephrine and dexamethasone in children with bronchiolitis.

OBJECTIVE: Using data from the Canadian Bronchiolitis Epinephrine Steroid Trial we assessed the cost-effectiveness of treatments with epinephrine and dexamethasone for infants between 6 weeks and 12 months of age with bronchiolitis. METHODS: An economic evaluation was conducted from both the societal and health care system perspectives including all costs during 22 days after enrollment. The effectiveness of therapy was measured by the duration of symptoms of feeding problems, sleeping problems, coughing, and noisy breathing. Comparators were nebulized epinephrine plus oral dexamethasone, nebulized epinephrine alone, oral dexamethasone alone, and no active treatment. Uncertainty around estimates was assessed through nonparametric bootstrapping. RESULTS: The combination of nebulized epinephrine plus oral dexamethasone was dominant over the other 3 comparators in that it was both the most effective and least costly. Average societal costs were $1115 (95% credible interval [CI]: 919-1325) for the combination therapy, $1210 (95% CI: 1004-1441) for no active treatment, $1322 (95% CI: 1093-1571) for epinephrine alone, and $1360 (95% CI: 1124-1624) for dexamethasone alone. The average time to curtailment of all symptoms was 12.1 days (95% CI: 11-13) for the combination therapy, 12.7 days (95% CI: 12-13) for no active treatment, 13.0 days (95% CI: 12-14) for epinephrine alone, and 12.6 days (95% CI: 12-13) for dexamethasone alone. CONCLUSION: Treating infants with bronchiolitis with a combination of nebulized epinephrine plus oral dexamethasone is the most cost-effective treatment option, because it is the most effective in controlling symptoms and is associated with the least costs.

Effect of exercise training on physical fitness in type II diabetes mellitus.

UNLABELLED: Few studies have compared changes in cardiorespiratory fitness between aerobic training only or in combination with resistance training. In addition, no study to date has compared strength gains between resistance training and combined exercise training in type II diabetes mellitus (T2DM). PURPOSE: We evaluated the effects of aerobic exercise training (A group), resistance exercise training (R group), combined aerobic and resistance training (A + R group), and sedentary lifestyle (C group) on cardiorespiratory fitness and muscular strength in individuals with T2DM. METHODS: Two hundred and fifty-one participants in the Diabetes Aerobic and Resistance Exercise trial were randomly allocated to A, R, A + R, or C. Peak oxygen consumption (V O(2peak)), workload, and treadmill time were determined after maximal exercise testing at 0 and 6 months. Muscular strength was measured as the eight-repetition maximum on the leg press, bench press, and seated row. Responses were compared between younger (aged 39-54 yr) and older (aged 55-70 yr) adults and between sexes. RESULTS: VO(2peak) improved by 1.73 and 1.93 mL O(2)*kg(-1)*min(-1) with A and A + R, respectively, compared with C (P < 0.05). Strength improvements were significant after A + R and R on the leg press (A + R: 48%, R: 65%), bench press (A + R: 38%, R: 57%), and seated row (A + R: 33%, R: 41%; P < 0.05). There was no main effect of age or sex on training performance outcomes. There was, however, a tendency for older participants to increase VO(2peak) more with A + R (+1.5 mL O(2)*kg(-1)*min(-1)) than with A only (+0.7 mL O(2)*kg(-1)*min(-1)). CONCLUSIONS: Combined training did not provide additional benefits nor did it mitigate improvements in fitness in younger subjects compared with aerobic and resistance training alone. In older subjects, there was a trend to greater aerobic fitness gains with A + R versus A alone.

Validity of information obtained from a method for estimating cancer costs from the perspective of patients and caregivers.

PURPOSE: We describe a method we developed for estimating cancer costs from the perspective of patients and caregivers and evidence supporting validity of estimates obtained. METHODS: To increase validity, interview questions were anchored to treatments; costs were divided into their components; most questions focused on facts; and the research team combined responses into cost estimates. Evidence for validity comes from a prospective study of breast cancer costs using this method. RESULTS: Estimates obtained using interview responses were similar to those from independent sources. Women reported being reimbursed $205 on average for prosthesis (government reimbursement =$200); paying $15.48 per night at cancer lodge (average rate =$17.52); receiving government illness insurance for 14.6 weeks at 53% of usual salary (governmental program covers 15 weeks at 55%). A priori hypotheses about relations of costs with other characteristics were also confirmed. For example, patients' weekly travel costs increased as a function of distance from the radiotherapy center, with patients living <25, 25-49 and ≥50 km away spending $54, $141 and $240, respectively (P<.0001); and the proportion of annual salary lost was 37% for self-employed workers compared to 18% for employees (P<.0001). CONCLUSIONS: Evidence to date supports the validity of estimates obtained using this method.

Treatment cost effectiveness in acute otitis media: A watch-and-wait approach versus amoxicillin.

In Canada, antimicrobial treatment is the most common approach for acute otitis media. The aim of the present study was to compare the cost effectiveness of treatment with amoxicillin versus a watch-and-wait approach (WAIT) within a Canadian pediatric setting. Four hundred eighty-eight children, six months to five years of age, who participated in a randomized controlled trial were included in the study. The average medication costs per patient were higher for the amoxicillin group ($17.26) than for the WAIT group ($4.33). However, both health care ($148.44 versus $162.48) and patient costs ($23.50 versus $31.87) were greater for the WAIT group. The mean cost of treatment for the amoxicillin group was $189.20, compared with $198.68 for the WAIT group. Amoxicillin may be cost effective in treating children with acute otitis media. The potential development of antimicrobial resistance was not addressed in the present study.
