RESUMO

PURPOSE: This cross-sectional prospective study measured utility values of upper eyelid dermatochalasis to quantify its impact on quality of life and assess cost-effectiveness of upper blepharoplasty. METHODS: Utility of dermatochalasis was assessed using the standard reference gamble and time trade-off methods, with dual anchor points of perfect eye function and perfect health. The utility value obtained was used to create a Markov model and run a cost-effectiveness analysis of blepharoplasty as a treatment for dermatochalasis while utilizing the societal perspective. RESULTS: One hundred three patients with dermatochalasis recruited from an urban outpatient ophthalmology clinic completed the utility survey. The authors determined utility values for dermatochalasis ranging from 0.74 to 0.92 depending on the measurement method (standard reference gamble/time trade-off) and anchor points. The cost-effectiveness analysis yielded an incremental cost-effectiveness ratio of $3,146 per quality-adjusted life year, well under the conventional willingness-to-pay threshold of $50,000 per quality-adjusted life year. Probabilistic sensitivity analysis with Monte Carlo simulation demonstrated that blepharoplasty would be cost-effective in 88.1% of cases at this willingness-to-pay threshold. CONCLUSIONS: Dermatochalasis has an impact on quality of life that is significantly associated with level of perceived functional impairment. Rising health care costs have underscored the importance of providing value-based treatment to patients, and the results of this study suggest that blepharoplasty is a cost-effective treatment option for symptomatic bilateral upper eyelid dermatochalasis.

RESUMO

OBJECTIVE: To explore whether using a single matched or composite outcome might affect the results of previous randomized controlled trials (RCTs) testing exercise for non-specific low back pain (NSLBP). The first objective was to explore whether a single matched outcome generated greater standardized mean differences (SMDs) when compared with the original unmatched primary outcome SMD. The second objective was to explore whether a composite measure, composed of matched outcomes, generated a greater SMD when compared with the original primary outcome SMD. DESIGN: We conducted exploratory secondary analyses of data. SETTING: Seven RCTs were included, of which 2 were based in the USA (University research clinic, Veterans Affairs medical center) and the UK (primary care clinics, nonmedical centers). One each were based in Norway (clinics), Brazil (primary care), and Japan (outpatient clinics). PARTICIPANTS: The first analysis comprised 1) 5 RCTs (n=1033) that used an unmatched primary outcome but included (some) matched outcomes as secondary outcomes, and the second analysis comprised 2) 4 RCTs (n=864) that included multiple matched outcomes by developing composite outcomes (N=1897). INTERVENTION: Exercise compared with no exercise. MAIN OUTCOME MEASURES: The composite consisted of standardized averaged matched outcomes. All analyses replicated the RCTs' primary outcome analyses. RESULTS: Of 5 RCTs, 3 had greater SMDs with matched outcomes (pooled effect SMD 0.30 [95% confidence interval {CI} 0.04, 0.56], P=.02) compared with an unmatched primary outcome (pooled effect SMD 0.19 [95% CI -0.03, 0.40] P=.09). Of 4 composite outcome analyses, 3 RCTs had greater SMDs in the composite outcome (pooled effect SMD 0.28 [95% CI 0.05, 0.51] P=.02) compared with the primary outcome (pooled effect SMD 0.24 [95% CI -0.04, 0.53] P=.10). CONCLUSIONS: These exploratory analyses suggest that using an outcome matched to exercise treatment targets in NSLBP RCTs may produce greater SMDs than an unmatched primary outcome. Composite outcomes could offer a meaningful way of investigating superiority of exercise than single domain outcomes.

RESUMO

BACKGROUND: Yoga interventions can improve function and reduce pain in persons with chronic low back pain (cLBP). OBJECTIVE: Using data from a recent trial of yoga for military veterans with cLBP, we analyzed the incremental cost-effectiveness of yoga compared with usual care. METHODS: Participants (n=150) were randomized to either 2× weekly, 60-minute yoga sessions for 12 weeks, or to delayed treatment (DT). Outcomes were measured at 12 weeks, and 6 months. Quality-adjusted life years (QALYs) were measured using the EQ-5D scale. A 30% improvement on the Roland-Morris Disability Questionnaire (primary outcome) served as an additional effectiveness measure. Intervention costs including personnel, materials, and transportation were tracked during the study. Health care costs were obtained from patient medical records. Health care organization and societal perspectives were examined with a 12-month horizon. RESULTS: Incremental QALYs gained by the yoga group over 12 months were 0.043. Intervention costs to deliver yoga were $307/participant. Negligible differences in health care costs were found between groups. From the health care organization perspective, the incremental cost-effectiveness ratio to provide yoga was $4488/QALY. From the societal perspective, yoga was "dominant" providing both health benefit and cost savings. Probabilistic sensitivity analysis indicates an 89% chance of yoga being cost-effective at a willingness-to-pay of $50,000. A scenario comparing the costs of yoga and physical therapy suggest that yoga may produce similar results at a much lower cost. DISCUSSION/CONCLUSIONS: Yoga is a cost-effective treatment for reducing pain and disability among military veterans with cLBP.

RESUMO

OBJECTIVES: The primary aim of this study was to examine differences in yoga practice between persons with and without chronic pain. Secondarily, we describe use of the Essential Properties of Yoga Questionnaire, Short Form (EPYQ-SF) for self-report. DESIGN: Participants were members of an existing cohort of veterans who completed a 2015-2016 survey focused on pain and nonpharmacological health practices. Cohort members who reported yoga in the past year [n=174 (9.4%) of 1850] were eligible for the present study, which used multiple-contact mixed-mode survey methodology to collect data on yoga practices. The EPYQ-SF was used to assess properties and context of yoga practice. Practice patterns were compared for participants with and without chronic pain. To explore potential reasons for reported yoga practice patterns, focused semistructured interviews were conducted with a subset of participants. RESULTS: Of 174 participants contacted, 141 (82%) returned the yoga questionnaire and 110 (78% of respondents) were still practicing yoga. Among yoga practitioners, 41 (37%) had chronic pain. Practitioners with chronic pain reported gentler (2.8 vs. 3.1, 5-point scale) and less active (2.9 vs. 3.3) yoga practice than those without. Those with chronic pain attended yoga studios less frequently and reported shorter yoga practices than those without. Most yoga practice was self-directed and at home. CONCLUSIONS: Differences in yoga practice of persons with and without chronic pain have implications for implementation of yoga interventions for chronic pain. Future interventions should focus on alternative individual delivery formats or addressing barriers to group practice among people with chronic pain.

RESUMO

BACKGROUND: Growth-based drug susceptibility testing (DST) is the reference standard for diagnosing drug-resistant tuberculosis (TB), but standard time to result (TTR) is typically ≥ 3 weeks. Rapid tests can reduce that TTR to days or hours, but accuracy may be lowered. In addition to the TTR and test accuracy, the cost of a diagnostic test may affect whether it is adopted in clinical settings. We examine the cost-effectiveness of rapid diagnostics for extremely drug-resistant TB (XDR-TB) in three different high-prevalence settings. METHODS: 1128 patients with confirmed TB were enrolled at clinics in Mumbai, India; Chisinau, Moldova; and Port Elizabeth, South Africa. Patient sputum samples underwent DST for first and second line TB drugs using 2 growth-based (MGIT, MODS) and 2 molecular (Pyrosequencing [PSQ], line-probe assays [LPA]) assays. TTR was the primary measure of effectiveness. Sensitivity and specificity were also evaluated. The cost to perform each test at each site was recorded and included test-specific materials, personnel, and equipment costs. Incremental cost-effectiveness ratios were calculated in terms of $/day saved. Sensitivity analyses examine the impact of batch size, equipment, and personnel costs. RESULTS: Our prior results indicated that the LPA and PSQ returned results in a little over 1 day. Mean cost per sample without equipment or overhead was $23, $28, $33, and $41 for the MODS, MGIT, PSQ, and LPA, respectively. For diagnosing XDR-TB, MODS was the most accurate, followed by PSQ, and LPA. MODS was quicker and less costly than MGIT. PSQ and LPA were considerably faster but cost more than MODS. Batch size and personnel costs were the main drivers of cost variation. CONCLUSIONS: Multiple factors must be weighed when selecting a test for diagnosis of XDR-TB. Rapid tests can greatly improve the time required to diagnose drug-resistant TB, potentially improving treatment success, and preventing the spread of XDR-TB. Faster time to result must be weighed against the potential for reduced accuracy, and increased costs. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02170441 .

RESUMO

Yoga-based practices (YBP) typically involve a combination of movement sequences, conscious regulation of the breath, and techniques to engage attention. However, little is known about whether effects of YBP result from the synergistic combination of these components, or whether a subset may yield similar effects. In this study we compared the effect of a movement-focused practice and a breath-focused practice on stress parameters (perceived stress and salivary cortisol) and sustained attention (response inhibition) in yoga naïve university students. While participants of both programs showed a reduction in perceived stress and salivary cortisol, only the breath-focused group showed improvements in sustained attention. In addition, improvement in sustained attention was correlated with reduction in perceived stress but not with reduction in salivary cortisol. We discuss these findings in the context of a theoretical framework outlining bottom-up neurophysiological and top-down neurocognitive mechanisms hypothesized to be engaged by YBP.

RESUMO

BACKGROUND: The loss of mobility during aging impacts independence and leads to further disability, morbidity, and reduced life expectancy. Our objective was to examine the feasibility and safety of conducting a randomized controlled trial of yoga for older adults at risk for mobility limitations. METHODS: Sedentary older adults (n = 46; age 60-89) were recruited and randomized to either yoga or a health education comparison group. Yoga sessions (60-min) occurred 2x weekly, and 90-min health education sessions occurred weekly, for 10 weeks. The primary outcomes were recruitment rate, intervention attendance, and retention at assessments. Adverse event rates and participant satisfaction were also measured. Physical performance measures of gait, balance, and strength and self-report outcome measures were administered at baseline and 10-weeks. RESULTS: Recruitment lasted 6 months. Retention of participants at the 10-week follow-up was high (89% - performance measures; 98% - self-report questionnaires). Attendance was good with 82% of yoga and 74% of health education participants attending at least 50% of the sessions. No serious adverse events were reported. Patient satisfaction with the interventions was high. The mean effect size for the physical performance measures was 0.35 with some over 0.50. The mean effect size for self-report outcome measures was 0.36. CONCLUSIONS: Results indicate that it is feasible to conduct a larger RCT of yoga for sedentary older adults at risk for mobility problems. The yoga and comparison interventions were safe, well accepted, and well attended. Effect sizes suggest yoga may have important benefits for this population and should be studied further.

RESUMO

BACKGROUND AND AIMS: The extent to which hepatitis C (HCV) treatment uptake is improved following introduction of interferon-free direct-acting antiviral (DAA) treatments is unknown. The purpose of this study was to determine HCV patient engagement and barriers to care for accessing DAA treatments in a real-world setting. METHODS: Patients with HCV viremia at high risk for fibrosis were identified using the Veterans Affairs (VA) registry within San Diego's VA in October 2014. Patients not enrolled in HCV clinic were systematically contacted by letter and phone. Logistic regression was used to examine patient factors associated with subsequent engagement in care over 12-20 months. RESULTS: In the local registry of 2089 patients, 481 were identified with high-risk fibrosis scores. Of those, 380 (79%) were eligible for antiviral treatment, and 178/380 (47%) patients were actively followed in clinic. The remaining 202/380 (53%) patients were never seen by a HCV clinic provider or lost to follow-up. Of these, 114/380 (30%) of the treatment-eligible cohort remained non-engaged in care following outreach. Compared with patients engaged in care, non-engaged patients were significantly more likely to have homelessness, COPD comorbidity, or active alcohol or/and drug use. Overall 74.4% of patients engaged in HCV clinic received antiviral treatment. CONCLUSIONS: A significant portion of eligible HCV patients could not be engaged in treatment after a programmatic outreach effort. These data indicate that more sustained or innovative outreach efforts are needed in order to maximize treatment access, with specific interventions targeting those with unstable housing and active alcohol/substance use disorders.

RESUMO

BACKGROUND: The spectrum of gastroenterology-related diseases related to obesity is growing. Few clinical tools exist to aid in clinician-guided dietary counseling. GOALS: (1) Develop and validate a 1-page diet history form that would provide information on dietary factors that can contribute to gastrointestinal (GI) illness and to assess adherence to the Mediterranean diet; and (2) evaluate the form in a general GI clinic to determine its potential utility as a clinical tool. STUDY: A 1-page diet history form was developed and underwent qualitative and quantitative validation in comparison to a formal diet evaluation by a registered dietitian. The form was then evaluated in consecutive patients attending a general GI clinic, and analyzed for overall diet content, compliance with a Mediterranean diet, and presence of high-risk (red flag) dietary behaviors. RESULTS: The form was evaluated in 134 patients. In a validation cohort (n=30) the qualitative dietary components measured were highly concordant with a formal dietary interview. Total daily calorie intake correlated with formal dietary review (R=0.61), but tended to underestimate total calories due to less precision in portion size. The prospective cohort (n=104) patients had a mean body mass index of 29.8. Overall, 52.9% were obese, 50% had metabolic syndrome, and 51% had a primary GI illness directly impacted by dietary factors (gastroesophageal reflux, irritable bowel, fatty liver). Overall, 85.6% of patients documented red flag behaviors. Patients with obesity trended for more red flags than overweight or normal body mass index groups. CONCLUSION: A 1-page diet questionnaire correlated well with formal dietary assessment and identified clinically relevant dietary interventions in a high percentage of GI patients.

RESUMO

BACKGROUND: Algorithms for the diagnosis, management, and follow-up have been proposed for patients hospitalized for inflammatory bowel disease (IBD) colitis flare. The degree to which providers adhere to these algorithms is unknown. This study evaluated the quality of care in IBD patients hospitalized for disease-associated exacerbations and factors correlated with higher degrees of care. METHODS: Retrospective chart review of 34 patients during 60 admissions to the medicine service for IBD colitis exacerbation between 2005 and 2012 at the Veterans Affairs San Diego Medical Center. Examined factors included laboratory testing, timing of consultation and intravenous steroids, abdominal imaging, endoscopic examination, venous thromboembolism (VTE) prophylaxis, narcotic use, Clostridium difficile and cytomegalovirus testing, symptomatology at discharge, timing of follow-up, and rates of readmission and mortality. RESULTS: Quality of care varied among the factors studied, ranging from 30.5 % for pharmacologic VTE prophylaxis to 84.7 % for gastroenterology consultation within 24 h. Of 60 admissions, 22 % were not tested for C. difficile. Fifteen percent of patients were discharged before meeting commonly used discharge criteria. Eighty percent were seen in clinic at any time post-discharge; 6.7 % were readmitted; 10 % were lost to follow-up; 1.7 % opted for outside follow-up; and 1.7 % expired. CONCLUSIONS: The quality of care for patients admitted with IBD colitis flares is variable. These data outline opportunities for improvement, particularly in regard to pain management, VTE prophylaxis, and follow-up. Further studies are needed to test intervention strategies for practice improvement.

RESUMO

BACKGROUND & AIMS: Patients with hepatitis C virus (HCV) infection with psychiatric disorders and/or substance abuse face significant barriers to antiviral treatment. New strategies are needed to improve treatment rates and outcomes. We investigated whether an integrated care (IC) protocol, which includes multidisciplinary care coordination and patient case management, could increase the proportion of patients with chronic HCV infection who receive antiviral treatment (a combination of interferon-based and direct-acting antiviral agents) and achieve a sustained virologic response (SVR). METHODS: We performed a prospective randomized trial at 3 medical centers in the United States. Participants (n = 363 patients attending HCV clinics) had been screened and tested positive for depression, post-traumatic stress disorder, and/or substance use; they were assigned randomly to groups that received IC or usual care (controls) from March 2009 through February 2011. A midlevel mental health practitioner was placed at each HCV clinic to provide IC with brief mental health interventions and case management, according to formal protocol. The primary end point was SVR. RESULTS: Of the study participants, 63% were non-white, 51% were homeless in the past 5 years, 64% had psychiatric illness, 65% were substance abusers within 1 year before enrollment, 57% were at risk for post-traumatic stress disorder, 71% had active depression, 80% were infected with HCV genotype 1, and 23% had advanced fibrosis. Over a mean follow-up period of 28 months, a greater proportion of patients in the IC group began receiving antiviral therapy (31.9% vs 18.8% for controls; P = .005) and achieved a SVR (15.9% vs 7.7% of controls; odds ratio, 2.26; 95% confidence interval, 1.15-4.44; P = .018). There were no differences in serious adverse events between groups. CONCLUSIONS: Integrated care increases the proportion of patients with HCV infection and psychiatric illness and/or substance abuse who begin antiviral therapy and achieve SVRs, without serious adverse events.

RESUMO

OBJECTIVES: We examined the impact of transitioning clients from a mental health clinic to a patient-centered medical home (PCMH) on mental health recovery. METHODS: We drew data from a large US County Behavioral Health Services administrative data set. We used propensity score analysis and multilevel modeling to assess the impact of the PCMH on mental health recovery by comparing PCMH participants (n = 215) to clients receiving service as usual (SAU; n = 22,394) from 2011 to 2013 in San Diego County, California. We repeatedly assessed mental health recovery over time (days since baseline assessment range = 0-1639; mean = 186) with the Illness Management and Recovery (IMR) scale and Recovery Markers Questionnaire. RESULTS: For total IMR (log-likelihood ratio χ(2)[1] = 4696.97; P < .001) and IMR Factor 2 Management scores (log-likelihood ratio χ(2)[1] = 7.9; P = .005), increases in mental health recovery over time were greater for PCMH than SAU participants. Increases on all other measures over time were similar for PCMH and SAU participants. CONCLUSIONS: Greater increases in mental health recovery over time can be expected when patients with severe mental illness are provided treatment through the PCMH. Evaluative efforts should be taken to inform more widespread adoption of the PCMH.

RESUMO

IMPORTANCE: In older adults reduced mobility is common and is an independent risk factor for morbidity, hospitalization, disability, and mortality. Limited evidence suggests that physical activity may help prevent mobility disability; however, there are no definitive clinical trials examining whether physical activity prevents or delays mobility disability. OBJECTIVE: To test the hypothesis that a long-term structured physical activity program is more effective than a health education program (also referred to as a successful aging program) in reducing the risk of major mobility disability. DESIGN, SETTING, AND PARTICIPANTS: The Lifestyle Interventions and Independence for Elders (LIFE) study was a multicenter, randomized trial that enrolled participants between February 2010 and December 2011, who participated for an average of 2.6 years. Follow-up ended in December 2013. Outcome assessors were blinded to the intervention assignment. Participants were recruited from urban, suburban, and rural communities at 8 centers throughout the United States. We randomized a volunteer sample of 1635 sedentary men and women aged 70 to 89 years who had physical limitations, defined as a score on the Short Physical Performance Battery of 9 or below, but were able to walk 400 m. INTERVENTIONS: Participants were randomized to a structured, moderate-intensity physical activity program (n = 818) conducted in a center (twice/wk) and at home (3-4 times/wk) that included aerobic, resistance, and flexibility training activities or to a health education program (n = 817) consisting of workshops on topics relevant to older adults and upper extremity stretching exercises. MAIN OUTCOMES AND MEASURES: The primary outcome was major mobility disability objectively defined by loss of ability to walk 400 m. RESULTS: Incident major mobility disability occurred in 30.1% (246 participants) of the physical activity group and 35.5% (290 participants) of the health education group (hazard ratio [HR], 0.82 [95% CI, 0.69-0.98], P = .03).Persistent mobility disability was experienced by 120 participants (14.7%) in the physical activity group and 162 participants (19.8%) in the health education group (HR, 0.72 [95% CI, 0.57-0.91]; P = .006). Serious adverse events were reported by 404 participants (49.4%) in the physical activity group and 373 participants (45.7%) in the health education group (risk ratio, 1.08 [95% CI, 0.98-1.20]). CONCLUSIONS AND RELEVANCE: A structured, moderate-intensity physical activity program compared with a health education program reduced major mobility disability over 2.6 years among older adults at risk for disability. These findings suggest mobility benefit from such a program in vulnerable older adults. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT01072500.

RESUMO

BACKGROUND: Interventions that promote adaptive emotion regulation (ER) skills reduce pain in patients with chronic pain; however, whether the effects of yoga practice on chronic low back pain (CLBP) are due to improvements in ER remains to be examined. OBJECTIVE: This study will test whether the effects of yoga on CLBP (improved pain severity and interference) are mediated by improved ER, the extent to which effects are related to specific aspects of ER, and the role of pain sensitization as a mediator or moderator of effects. In this study, pain sensitization will be assessed by quantitative sensory testing and gene expression profiles to examine whether pain sensitization moderates yoga's effects on pain or whether yoga and ER abilities reduce pain sensitization, leading to decreased pain severity and interference. METHODS: For this 2-arm parallel group blinded randomized controlled trial, we will enroll 204 adults with CLBP who will be randomized to receive the yoga (n=102) or a control stretching and strengthening (n=102) intervention, which are delivered via web-based synchronous biweekly 75-minute sessions over 12 weeks. Participants are encouraged to practice postures or exercises for 25 minutes on other days using accessible prerecorded practice videos that are sent to participants digitally. Participants will be assessed at 5 time points: baseline, midintervention (6 weeks), postintervention (12 weeks), and 3- and 6-month follow-ups. Assessments of ER, pain severity and interference, pain sensitivity including somatosensory and gene expression profiles, and physical strength and flexibility will be conducted at each visit. The fidelity of the interventions is assessed using a manualized checklist to evaluate recorded group sessions to ensure consistent instructor delivery. RESULTS: The primary outcome will be the mean change in pain severity as measured by the Brief Pain Inventory-Short Form at 12 weeks. The primary mechanism of action is ER measured by change in the Difficulties in Emotion Regulation Scale total score. Secondary outcomes include pain sensitivity, physical strength and flexibility, pain interference, and quality of life. A mediation path analysis and series of moderated mediation path analyses will be conducted to test the study hypotheses. As of January 2024, we have enrolled 138 participants. We expect the study to be completed by May 2025. CONCLUSIONS: The study will provide important data for evaluating whether improvements in ER are responsible for reduced pain perception and pain sensitivity as well as increased quality of life in the context of chronic pain. The study findings have important implications for determining the mechanism of action for yoga and possibly other mind-body interventions as nonpharmacological therapies for pain management. The results of the study will inform the content, delivery, and measures for intervention trials involving yoga as a modality for relieving pain and improving function.

RESUMO

OBJECTIVE: Diabetes is associated with reduced health-related quality of life (HRQoL). Information on the relationship between HRQoL and glucose-lowering medications in recently diagnosed type 2 diabetes (T2D) is limited. We assessed changes in HRQoL in participants with T2D receiving metformin plus one of four glucose-lowering medications in Glycemia Reduction Approaches in Diabetes: A Comparative Effectiveness Study (GRADE). RESEARCH DESIGN AND METHODS: A total of 5,047 participants, baseline mean age 57 years, with <10 years T2D duration and glycated hemoglobin level 6.8-8.5% and taking metformin monotherapy, were randomly assigned to glargine, glimepiride, liraglutide, or sitagliptin. HRQoL was evaluated at baseline for 4,885 participants, and at years 1, 2, and 3, with use of the self-administered version of the Quality of Well-being Scale (QWB-SA) and SF-36 physical (PCS) and mental (MCS) component summary scales. Linear models were used to analyze changes in HRQoL over time in intention-to-treat analyses. RESULTS: None of the medications worsened HRQoL. There were no differences in QWB-SA or MCS by treatment group at any time point. PCS scores improved with liraglutide versus other groups at year 1 only. Greater weight loss during year 1 explained half the improvement in PCS scores with liraglutide versus glargine and glimepiride. Liraglutide participants in the upper tertile of baseline BMI showed the greatest improvement in PCS scores at year 1. CONCLUSIONS: Adding liraglutide to metformin in participants within 10 years of T2D diagnosis showed improvement in the SF-36 PCS in comparisons with the other medications at 1 year, which was no longer significant at years 2 and 3. Improvement was related to weight loss and baseline BMI.

RESUMO

BACKGROUND & AIMS: The Veterans Health Administration (VHA) is the largest single provider of care for hepatitis C virus (HCV) infection in the United States. We analyzed the cost effectiveness of treatment with the HCV protease inhibitors boceprevir and telaprevir in a defined managed care population of 102,851 patients with untreated chronic genotype 1 infection. METHODS: We used a decision-analytic Markov model to examine 4 strategies: standard dual-therapy with pegylated interferon-alfa and ribavirin (PR), the combination of boceprevir and PR triple therapy, the combination of telaprevir and PR, or no antiviral treatment. A sensitivity analysis was performed. Sources of data included published rates of disease progression, the census bureau, and VHA pharmacy and hospitalization cost databases. RESULTS: The estimated costs for treating each patient were $8000 for PR, $31,300 for boceprevir and PR, and $41,700 for telaprevir and PR. Assuming VHA treatment rates of 22% and optimal rates of sustained virologic response, PR, boceprevir and PR, and telaprevir and PR would reduce relative liver-related deaths by 5.2%, 10.9%, and 11.5%, respectively. Increasing treatment rates to 50% would reduce liver-related deaths by 12%, 24.7%, and 26.1%, respectively. The incremental cost-effectiveness ratios were $29,184/quality-adjusted life-years for boceprevir and PR and $44,247/quality-adjusted life-years for telaprevir and PR vs only PR. With the current 22% treatment rate, total system-wide costs to adopt boceprevir and PR or telaprevir and PR would range from $708 to $943 million. CONCLUSIONS: Despite substantial up-front costs of treating HCV-infected patients in the VHA with PR, or telaprevir and PR, each regimen improves quality of life and extends life expectancy by reducing liver-related morbidity and mortality, and should be cost effective. Further efforts to expand access to direct-acting antiviral therapy are warranted.

RESUMO

BACKGROUND AND AIM: Iron deficiency anemia (IDA) is a common problem among the elderly, and often no cause is identified after routine upper endoscopy and colonoscopy exams. The purpose of this study was to determine the long-term outcomes and predictors of gastrointestinal pathology and death in patients with endoscopy-negative IDA. METHODS: This was a retrospective review of consecutive endoscopy negative-IDA patients during 2002-2004 at the VA San Diego Healthcare System. RESULTS: Mean age was 69.3 years (range 42-93), and included 105 men and nine women. Mean length of follow-up was 65.1 months. IDA resolved in 56 patients. None of these patients developed evidence of any clinically significant gastrointestinal pathology. The remaining 58 patients had persistent anemia (n = 47) or recurrent anemia (n = 11). Only 2/47 patients with persistent anemia were found to have clinically significant but benign gastrointestinal pathology during follow-up. In contrast, 6/11 patients with recurrent anemia were subsequently found to have gastrointestinal pathology. Deaths during follow-up occurred in 7 (12.5 %) patients with resolved anemia, compared with 20 (34.5 %) patients with recurrent or persistent anemia (p = 0.006). Significant independent predictors of death included persistent or recurrent anemia, anti-platelet or anticoagulant use, and congestive heart failure. CONCLUSIONS: Patients with iron deficiency anemia and negative upper endoscopy and colonoscopy often have a favorable outcome, especially if the anemia resolves with treatment. In patients with recurrent anemia a malignancy within reach of standard endoscopy and colonoscopy are possible, and repeating these procedures is warranted before consideration of further investigations.

RESUMO

PURPOSE: Cataracts are the leading cause of blindness worldwide and cause visual impairment for millions of adults in the United States. We compared the sensitivity of a vision-specific health-related quality of life (HRQOL) measure to that of multiple generic measures of HRQOL before and at 2 time points after cataract surgery. METHODS: Participants completed 1 vision-specific and 5 generic quality of life measures before cataract surgery, and again 1 and 6 months after surgery. Random effects modeling was used to measure changes over the three assessment points. RESULTS: The NEI-VFQ25 total score and all 11 subscales showed significant improvements during the first interval (baseline and 1 month). During the second interval (1-6 months post-surgery), significant improvements were observed on the total score and 5 of 11 NEI-VFQ25 subscales. There were significant increases in HRQOL during the first interval on some preference-based generic HRQOL measures, though changes during the second interval were mostly non-significant. None of the SF-36v2™ or SF6D scales changed significantly between any of the assessment periods. CONCLUSIONS: The NEI-VFQ25 was sensitive to changes in vision-specific domains of QOL. Some preference-based generic HRQOL measures were also sensitive to change and showed convergence with the NEI-VFQ25, but the effects were small. The SF-36v2™ and SF-6D did not change in a similar manner, possibly reflecting a lack of vision-related content. Studies seeking to document both the vision-specific and generic HRQOL improvements of cataract surgery should consider these results when selecting measures.

RESUMO

PURPOSE: The purpose of this study was to create and validate a mental health subscale for the Quality of Well-Being Self-Administered (QWB-SA). METHODS: The QWB-SA and other measures such as the Profile of Mood States (POMS), Medical Outcomes Study 36 Item Short Form (SF-36), EuroQOL 5D (EQ-5D), and Health Utilities Index Mark 2 (HUI) were administered to three samples: a general population (N = 3,844), a non-psychiatric medical population (N = 535), and a psychiatric population (N = 915). Independent expert ratings of which items represented the construct of mental health were used along with psychometric methods to develop and validate a 10-item QWB-SA mental health scale. RESULTS: The mental health scale demonstrated high internal consistency (Cronbach's alpha = 0.827-0.842) and strong correlations with other measures of mental health, such as the POMS (r = -0.77), mental health scale from the SF-36 (r = 0.72), EQ-5D mood item (r = 0.61), and HUI Emotion Scale (r = 0.59). It was not highly correlated with measures of physical health. Among the psychiatric population, the new mental health scale was moderately correlated with indicators of psychiatric problem severity. CONCLUSIONS: It is now possible to report outcomes and relationships with mental health in studies that use the QWB-SA. This new mental health subscale can also be used with the large volume of previously collected data using the QWB-SA to examine the impact of illnesses and interventions on mental health-related quality of life.

RESUMO

In addition to higher morbidity and mortality, Black adults have reported lower self-rated health than White adults. The purpose of this study was to evaluate the diminishing difference in self-rated health between races from 1972 to 2008. Data from 37,936 participants over a 36-year span of the General Social Survey were used to evaluate the effects of race and time on self-rated health. Results confirmed that Black adults reported significantly worse health than White adults. Overall health was rated slightly better across both groups as time went on ([Formula: see text] = .002, P < .0005). However, this increase in health ratings has slowed, even reversing with a decline in health ratings as of late ([Formula: see text] = -.014, P = .001). Significant interactions between race and time indicated that the racial difference on this self-rated health measure has changed over time. The rate of change in the difference has slowed over time ([Formula: see text] = -.010, P = .021), suggesting that the reduction in the racial difference in self-rated health may be decelerating.
