Visual ability of patients seeking outpatient low vision services in the United States.

ABSTRACT: IMPORTANCE:Most patients with low vision are elderly and have functional limitations from other health problems that could add to the functional limitations caused by their visual impairments. OBJECTIVE:To identify factors that contribute to visual ability measures in patients who present for outpatient low vision rehabilitation (LVR) services. DESIGN, SETTING, AND PARTICIPANTS:As part of a prospective, observational study of new patients seeking outpatient LVR, 779 patients from 28 clinical centers in the United States were enrolled in the Low Vision Rehabilitation Outcomes Study (LVROS) from April 25, 2008, through May 2, 2011. The Activity Inventory (AI), an adaptive visual function questionnaire, was administered to measure overall visual ability and visual ability in 4 functional domains (reading, mobility, visual motor function, and visual information processing) at baseline before LVR. The Geriatric Depression Scale, Telephone Interview for Cognitive Status, and Medical Outcomes Study 36-Item Short-Form Health Survey physical functioning questionnaires were also administered to measure patients' psychological, cognitive, and physical health states, respectively. MAIN OUTCOMES AND MEASURES:Predictors of visual ability and functional domains as measured by the AI. RESULTS:Among the 779 patients in the LVROS sample, the mean age was 76.4 years, 33% were male, and the median logMAR visual acuity score was 0.60 (0.40-0.90 interquartile range). Correlations were observed between logMAR visual acuity and baseline visual ability overall (r?=?-0.42) and for all functional domains. Visual acuity was the strongest predictor of visual ability (P ?

Project description:PurposeTo characterize functional complaints of new low-vision rehabilitation patients.DesignProspective observational study.ParticipantsThe Low Vision Rehabilitation Outcomes Study recruited 819 patients between 2008 and 2011 from 28 clinical centers in the United States.MethodsNew patients referred for low-vision rehabilitation were asked, "What are your chief complaints about your vision?" before their appointment. Full patient statements were transcribed as free text. Two methods assessed whether statements indicated difficulty in each of 13 functional categories: (1) assessment by 2 masked clinicians reading the statement, and (2) a computerized search of the text for specific words or word fragments. Logistic regression models were used to predict the influence of age, gender, and visual acuity on the likelihood of reporting a complaint in each functional category.Main outcome measuresPrevalence and risk factors for patient concerns within various functional categories.ResultsReading was the most common functional complaint (66.4% of patients). Other functional difficulties expressed by at least 10% of patients included driving (27.8%), using visual assistive equipment (17.5%), mobility (16.3%), performing in-home activities (15.1%), lighting and glare (11.7%), and facial recognition and social interactions (10.3%). Good agreement was noted between the masked clinician graders and the computerized algorithm for categorization of functional complaints (median κ of 0.84 across the 13 categories). Multivariate logistic regression models demonstrated that the likelihood of reading difficulties increased mildly with age (odds ratio, 1.4 per 10-year increment in age; 95% confidence interval, 1.3-1.6), but did not differ with visual acuity (P = 0.09). Additionally, men were more likely to report driving difficulties and difficulties related to lighting, whereas women were more likely to report difficulty with either in-home activities or facial recognition or social interaction (P<0.05 for all). Mobility concerns, defined as walking difficulty and out-of-home activities, showed no relationship to gender, age, or visual acuity.ConclusionsReading was the most commonly reported difficulty, regardless of the patient's diagnosis. Neither visual acuity nor gender were predictive of reading concerns, although, age showed a small effect. Addressing reading rehabilitation should be a cornerstone of low-vision therapy.

Project description:BackgroundIn the United States (U.S.), annual influenza vaccination has been recommended for all persons aged ≥6 months with the Healthy People 2020 coverage target of 70%. However, vaccination coverage has remained around 42-49% during the past eight influenza seasons. We sought to quantify influenza vaccination coverage and factors associated with vaccination in persons seeking outpatient medical care for an acute respiratory illness (ARI).MethodsWe enrolled outpatients aged ≥6 months with ARI from >50 U.S. clinics from 2011 to 2012 through 2018-2019 influenza seasons and tested for influenza with molecular assays. Vaccination status was based on documented receipt of the current season's influenza vaccine. We estimated vaccination coverage among influenza-negative study participants by study site, age, and season, and compared to state-level influenza coverage estimates in the general population based on annual immunization surveys. We used multivariable logistic regression to examine factors independently associated with receipt of influenza vaccines.ResultsWe enrolled 45,424 study participants with ARI who tested negative for influenza during the study period. Annual vaccination coverage among influenza-negative ARI patients and the general population in the participating states averaged 55% (range: 47-62%), and 52% (range: 46-54%), respectively. Among enrollees, coverage was highest among adults aged ≥65 years (82%; range, 80-85%) and lowest among adolescents aged 13-17 years (38%; range, 35-41%). Factors significantly associated with non-vaccination included non-White race, no college degree, exposure to cigarette smoke, absence of high-risk conditions, and not receiving prior season influenza vaccine.ConclusionsInfluenza vaccination coverage over eight seasons among outpatients with non-influenza respiratory illness was slightly higher than coverage in the general population but 15% lower than national targets. Increased efforts to promote vaccination especially in groups with lower coverage are warranted to attain optimal health benefits of influenza vaccine.

Project description:Importance:Benzodiazepines are implicated in a growing number of overdose-related deaths. Objectives:To quantify patterns in outpatient benzodiazepine prescribing and to compare them across specialties and indications. Design, Setting, and Participants:This serial cross-sectional study (January 1, 2003, through December 31, 2015) used nationally representative National Ambulatory Medical Care Survey data. The yearly population-based sample of outpatient visits among adults, ranging from 20?884 visits in 2003 (representing 737 million visits) to 24?273 visits in 2015 (representing 841 million visits) was analyzed. Prescribing patterns were examined by specialty and indication and used to calculate the annual coprescribing rate of benzodiazepines with other sedating medications. Data were analyzed from July 1, 2017, through November 30, 2018. Main Outcomes and Measures:Annual benzodiazepine visit rate. Results:Among the 386 457 ambulatory care visits from 2003 through 2015, a total of 919 benzodiazepine visits occurred in 2003 and 1672 in 2015, nationally representing 27.6 million and 62.6 million visits, respectively. The benzodiazepine visit rate doubled from 3.8% (95% CI, 3.2%-4.4%) to 7.4% (95% CI, 6.4%-8.6%; P?<?.001) of visits. Visits to primary care physicians accounted for approximately half of all benzodiazepine visits (52.3% [95% CI, 50.0%-54.6%]). The benzodiazepine visit rate did not change among visits to psychiatrists (29.6% [95% CI, 23.3%-36.7%] in 2003 to 30.2% [95% CI, 25.6%-35.2%] in 2015; P?=?.90), but increased among all other physicians, including primary care physicians (3.6% [95% CI, 2.9%-4.4%] to 7.5% [95% CI, 6.0%-9.5%]; P?<?.001). The benzodiazepine visit rate increased slightly for anxiety and depression (26.6% [95% CI, 22.6%-31.0%] to 33.5% [95% CI, 28.8%-38.6%]; P?=?.003) and neurologic conditions (6.8% [95% CI, 4.8%-9.5%] to 8.7% [95% CI, 6.2%-12.1%]; P?<?.001), but more so for back and/or chronic pain (3.6% [95% CI, 2.6%-4.9%] to 8.5% [95% CI, 6.0%-11.9%]; P?<?.001) and other conditions (1.8% [95% CI, 1.4%-2.2%] to 4.4% [95% CI, 3.7%-5.2%]; P?<?.001); use did not change for insomnia (26.9% [95% CI, 19.3%-36.0%] to 25.6% [95% CI, 15.3%-39.6%]; P?=?.72). The coprescribing rate of benzodiazepines with opioids quadrupled from 0.5% (95% CI, 0.3%-0.7%) in 2003 to 2.0% (95% CI, 1.4%-2.7%) in 2015 (P?<?.001); the coprescribing rate with other sedating medications doubled from 0.7% (95% CI, 0.5%-0.9%) to 1.5% (95% CI, 1.1%-1.9%) (P?<?.001). Conclusions and Relevance:The outpatient use of benzodiazepines has increased substantially. In light of increasing rates of overdose deaths involving benzodiazepines, understanding and addressing prescribing patterns may help curb the growing use of benzodiazepines.

Project description:BackgroundSpecialty societies in the United States identified low-value tests and procedures that contribute to waste and poor health care quality via implementation of the American Board of Internal Medicine Foundation's Choosing Wisely initiative.ObjectiveTo develop claims-based algorithms, to use them to estimate the prevalence of select Choosing Wisely services and to examine the demographic, health and health care system correlates of low-value care at a regional level.DesignUsing Medicare data from 2006 to 2011, we created claims-based algorithms to measure the prevalence of 11 Choosing Wisely-identified low-value services and examined geographic variation across hospital referral regions (HRRs). We created a composite low-value care score for each HRR and used linear regression to identify regional characteristics associated with more intense use of low-value services.PatientsFee-for-service Medicare beneficiaries over age 65.Main measuresPrevalence of selected Choosing Wisely low-value services.Key resultsThe national average annual prevalence of the selected Choosing Wisely low-value services ranged from 1.2% (upper urinary tract imaging in men with benign prostatic hyperplasia) to 46.5% (preoperative cardiac testing for low-risk, non-cardiac procedures). Prevalence across HRRs varied significantly. Regional characteristics associated with higher use of low-value services included greater overall per capita spending, a higher specialist to primary care ratio and higher proportion of minority beneficiaries.ConclusionsIdentifying and measuring low-value health services is a prerequisite for improving quality and eliminating waste. Our findings suggest that the delivery of wasteful and potentially harmful services may be a fruitful area for further research and policy intervention for HRRs with higher per-capita spending. These findings should inform action by physicians, health systems, policymakers, payers and consumer educators to improve the value of health care by targeting services and areas with greater use of potentially inappropriate care.

Project description:Gender-affirming surgery (GAS) is among the most rapidly growing and expanding subfields in plastic surgery due to increased awareness, decreased stigma, rising demand, and improved access for transgender and gender non-conforming individuals (TGNC). In order to address potential barriers and facilitators in GAS education and training, there is a need to explore the experiences of TGNC individuals. The purpose of this study was to qualitatively explore the factors that influence TGNC patient experiences in surgical consultation for GAS. Targeted recruitment was used to recruit and enroll participants who identified as TGNC and who had undergone consultation with a surgeon to discuss GAS. Semi-structured interviews were used to explore patient experiences with GAS. Recorded audio from these interviews was later transcribed verbatim. Open coding of these transcripts was then performed independently by 3 individual members of the research team using the consensual qualitative coding methods. Fifteen interviews were conducted (transmale, n = 7; transfemale, n = 4; gender non-conforming/non-binary, n = 4). Participants frequently expressed worry and frustration over insurance coverage and exorbitant out-of-pocket expense, whether actual or perceived. Logistical barriers were the most frequently cited category of barriers. The majority of participants made at least 1 reference to relying on others during the process of insurance pre-authorization. The majority of participants described their interactions with surgeons as positive, indicating that they felt comfortable during consultation and that their surgeons ensured their understanding. Our findings provide important insight into this often stressful and challenging process. Ensuring a welcoming, safe, and gender-affirming environment and experience for these individuals is essential. These findings may help to guide future education for medical students, trainees, clinic staff, and surgeons, as well as to direct changes necessary to improve the patient experience in clinics and hospitals for TGNC individuals undergoing consultation for GAS.

Project description:Involvement of clinical pharmacists in the ICU attenuates costs, avoids adverse drug events, and reduces morbidity and mortality. This survey assessed services and activities of ICU pharmacists.DesignA 27-question, pretested survey.Setting1,220 U.S. institutions.SubjectsCritical care pharmacists.InterventionsElectronic questionnaire of pharmacy services and activities across clinical practice, education, scholarship, and administration.Measurements and main resultsA total of 401 (response rate of 35.4%) surveys representing 493 ICUs were completed. Median daily ICU census was 12 (interquartile range, 6-20) beds with 1 (interquartile range, 1-1.5) pharmacist full-time equivalent per ICU. Direct clinical ICU pharmacy services were available in 70.8% of ICUs. Pharmacists attended rounds 5 days (interquartile range, 4-5 d) per week with a median patient-to-pharmacist ratio of 17 (interquartile range, 12-26). The typical workweek consisted of 50% (interquartile range, 40-60%) direct ICU patient care, 10% (interquartile range, 8-16%) teaching, 8% (interquartile range, 5-18%) order processing, 5% (interquartile range, 0-20%) direct non-ICU patient care, 5% (interquartile range, 2-10%) administration, 5% (interquartile range, 0-10%) scholarship, and 0% (interquartile range, 0-5%) drug distribution. Common clinical activities as a percentage of the workweek were reviewing drug histories (28.5%); assessing adverse events (27.6%); and evaluating (26.1%), monitoring (23.8%), and managing (21.4%) drug therapies. Services were less likely to occur overnight or on weekends. Telemedicine was rarely employed. Dependent prescriptive authority (per protocol or via practice agreements) was available to 51.1% of pharmacists and independent prescriptive authority was provided by 13.4% of pharmacists. Educational services most frequently provided were inservices (97.6%) and experiential training of students or residents (89%). Education of ICU healthcare members was provided at a median of 5 times/mo (interquartile range, 3-15 times/mo). Most respondents were involved with ICU or departmental policies/guidelines (84-86.8%) and 65.7% conducted some form of scholarship.ConclusionsICU pharmacists have diverse and versatile responsibilities and provide several key clinical and nonclinical services. Initiatives to increase the availability of services are warranted.
