Disparities in Care for Low-Income Patients with Cirrhosis: Implementing an Innovative Outpatient Clinic for Refractory Ascites in a Safety Net Hospital.

BACKGROUND: Disparities in life-saving interventions for low-income patients with cirrhosis necessitate innovative models of care. AIM: To implement a novel generalist-led FLuid ASPiration (FLASP) clinic to reduce emergency department (ED) care for refractory ascites. SETTING: A large safety net hospital in Los Angeles. PARTICIPANTS: MediCal patients with paracentesis in the ED from 6/1/2020 to 1/31/2021 or in FLASP clinic or the ED from 3/1/2021 to 4/30/2022. PROGRAM DESCRIPTION: According to RE-AIM, adoption obtained administrative endorsement and oriented ED staff. Reach engaged ED staff and eligible patients with timely access to FLASP. Implementation trained FLASP clinicians in safer, guideline-based paracentesis, facilitated timely access, and offered patient education and support. PROGRAM EVALUATION: After FLASP clinic opened, significantly fewer ED visits were made by patients discharged after paracentesis [rate ratio (RR) of 0.33 (95% CI 0.28, 0.40, p < 0.0001)] but not if subsequently hospitalized (RR = 0.88, 95% CI 0.70, 1.11). Among 2685 paracenteses in 225 FLASP patients, complications were infrequent: 39 (1.5%) spontaneous bacterial peritonitis, 265 (9.9%) acute kidney injury, and 2 (< 0.001%) hypotension. FLASP patients rated satisfaction highly on a Likert-type question. DISCUSSION: Patients with refractory ascites in large safety net hospitals may benefit from an outpatient procedure clinic instead of ED care.

Trends in Race/Ethnicity of Pediatric Residents and Fellows: 2007-2019.

BACKGROUND AND OBJECTIVES: A diverse pediatric workforce reflecting the racial/ethnic representation of the US population is an important factor in eliminating health inequities. Studies reveal minimal improvements over time in the proportions of underrepresented in medicine (URiM) physicians; however, studies assessing trends in pediatric URiM trainee representation are limited. Our objective was to evaluate longitudinal trends in racial/ethnic representation among a cross-section of US pediatric trainees and to compare it to the US population. METHODS: Repeated cross-sectional study of graduate medical education census data on self-reported race/ethnicity of pediatric residents and subspecialty fellows from 2007 to 2019. To evaluate trends in URiM proportions over time, the Cochran-Armitage test was performed. Data on self-reported race/ethnicity of trainees were compared with the general population data over time by using US Census Bureau data. RESULTS: Trends in URiM proportions were unchanged in residents (16% in 2007 to 16.5% in 2019; P = .98) and, overall, decreased for fellows (14.2% in 2007 to 13.5% in 2019; P = .002). URiM fellow trends significantly decreased over time in neonatal-perinatal medicine (P < .001), infectious diseases (P < .001), and critical care (P = .006) but significantly increased in endocrinology (P = .002) and pulmonology (P = .009). Over time, the percentage of URiM pediatric trainee representation was considerably lower compared to the US population. CONCLUSIONS: The continued underrepresentation of URiM pediatric trainees may perpetuate persistent health inequities for minority pediatric populations. There is a critical need to recruit and retain pediatric URiM residents and subspecialty fellows.

Quantitative Computed Tomography Assessment of Bone Deficits in Ambulatory Children and Adolescents with Spina Bifida: Importance of Puberty.

Pathologic fractures of the femur and tibia are common in youth with spina bifida (SB). These fractures may be associated with deficient bone accrual due to decreased ambulation and skeletal loading. This prospective cohort study used quantitative computed tomography (QCT) to assess three-dimensional (3D) bone properties in children and adolescents with SB. Eighty-three ambulatory youth with SB underwent QCT imaging of the tibia at up to four annual visits between ages 6 to 16 years (294 total visits averaging 3.5 visits/patient). A total of 177 controls without disability and 10 non-ambulatory youth with SB underwent imaging once. Bone geometric properties (cortical bone area, cross-sectional area, cortical thickness, cortical density, and moments of inertia) were measured at the mid-diaphysis (50% of bone length); cross-sectional area, cancellous density, and density-weighted area were measured in the proximal (13% of bone length) and distal (90% of bone length) metaphyses. Bone properties were compared between the ambulatory SB and control participants, among SB neurosegmental subgroups (sacral, low lumbar, mid lumbar and above) as a function of pubertal stage (prepubertal, pubertal, postpubertal), and considering SB type (myelomeningocele, lipomyelomeningocele) using linear mixed effects models adjusted for sex, age, height percentile, and body mass index (BMI) percentile. Only cancellous density of both metaphyses and weighted area of the proximal metaphysis differed between ambulatory children with SB and controls before puberty. However, significant deficits in all bone properties manifested during and after puberty as moderate bone growth in the SB group failed to keep pace with the large increases normally observed during puberty. The bone deficits primarily affected patients with myelomeningocele, and similar deficits were observed at all neurosegmental levels except that cancellous density was closer to normal in the sacral group. Descriptive analysis of the 10 non-ambulatory youth with SB showed greater bone deficits than ambulatory children, particularly for cancellous density in the distal metaphysis. © 2020 The Authors.

Improved fracture prediction using different fracture risk assessment tool adjustments in HIV-infected women.

OBJECTIVES: A fracture risk assessment tool (FRAX) using clinical risk factors (CRFs) alone underestimates fracture risk in HIV-infected men. Our objective was to determine whether accuracy of FRAX would be improved by considering HIV as a cause of secondary osteoporosis, and further improved with addition of dual-energy X-ray absorptiometry parameters in HIV-infected women. DESIGN: Subgroup analysis of Women's Interagency HIV Study. METHODS: We included 1148 women (900 HIV-infected and 248 uninfected) over age 40 with data to approximate FRAX CRFs and 10-year observational data for incident fragility fractures; 181 (20%) HIV-infected women had dual-energy X-ray absorptiometry data. Accuracy of FRAX was evaluated by the observed/estimated ratios of fracture in four models: CRFs alone; CRFs with HIV included as a cause of secondary osteoporosis; CRFs and femoral neck bone mineral density (FN BMD); and CRFs, FN BMD and trabecular bone score. RESULTS: FRAX using CRFs were less accurate in HIV-infected than uninfected women for major osteoporotic (observed/estimated ratio: 5.05 vs. 3.26, P < 0.001) and hip fractures (observed/estimated ratio: 19.78 vs. 7.94, P < 0.001), but improved when HIV was included as a cause of secondary osteoporosis. Among HIV-infected women, FRAX accuracy improved further with addition of FN BMD (observed/estimated ratio: 4.00) for hip fractures, but no further with trabecular bone score. CONCLUSION: FRAX using CRFs alone underestimated fracture risk more in older HIV-infected women than otherwise similar uninfected women. Accuracy is improved when including HIV as a cause of secondary osteoporosis for both major osteoporotic and hip fractures, whereas addition of FN BMD only improved accuracy for hip fracture.

The Effect of Utilization Review on Emergency Department Operations.

STUDY OBJECTIVE: Increasingly, hospitals are using utilization review software to reduce hospital admissions in an effort to contain costs. Such practices have the potential to increase the number of unsafe discharges, particularly in public safety-net hospitals. Utilization review software tools are not well studied with regard to their effect on emergency department (ED) operations. We study the effect of prospectively used admission decision support on ED operations. METHODS: In 2012, Los Angeles County + University of Southern California Medical Center implemented prospective use of computerized admission criteria. After implementation, only ED patients meeting primary review (diagnosis-based criteria) or secondary review (medical necessity as determined by an on-site emergency physician) were assigned inpatient beds. Data were extracted from electronic medical records from September 2011 through December 2013. Outcomes included operational metrics, 30-day ED revisits, and 30-day admission rates. Excluding a 6-month implementation period, monthly summary metrics were compared pre- and postimplementation with nonparametric and negative binomial regression methods. All adult ED visits, excluding incarcerated and purely behavioral health visits, were analyzed. The primary outcomes were disposition rates. Secondary outcomes were 30-day ED revisits, 30-day admission rate among return visitors to the ED, and estimated cost. RESULTS: Analysis of 245,662 ED encounters was performed. The inpatient admission rate decreased from 14.2% to 12.8%. Increases in discharge rate (82.4% to 83.4%) and ED observation unit utilization (2.5% to 3.4%) were found. Thirty-day revisits increased (20.4% to 24.4%), although the 30-day admission rate decreased (3.2% to 2.8%). Estimated cost savings totaled $193.17 per ED visit. CONCLUSION: The prospective application of utilization review software in the ED led to a decrease in the admission rate. This was tempered by a concomitant increase in ED observation unit utilization and 30-day ED revisits. Cost savings suggest that resources should be redirected to the more highly affected ED and ED observation unit, although more work is needed to confirm the generalizability of these findings.

Hormone replacement therapy and the association with coronary heart disease and overall mortality: clinical application of the timing hypothesis.

Conclusions from randomized controlled trial (RCT) data over the past 10 years has spanned from presumed harm to consistency with observational data that hormone replacement therapy (HRT) decreases the risk for coronary heart disease (CHD) as well as overall mortality in women who are recently postmenopausal. Multiple clinical studies including randomized trials and observational studies converge with animal experimentation to show a consistency that HRT decreases CHD risk and overall mortality in primary prevention when HRT is started at the time of or soon after menopause. The totality of data supports the "timing" hypothesis that posits that HRT effects are dependent on when HRT is started in relation to age and/or time-since-menopause. The totality of data shows that HRT decreases CHD and overall morality when started in women who are less than 60 years old and/or less than 10 years postmenopausal, providing a "window-of-opportunity". Further evidence shows that women who start HRT when in their 50s and continued for 5-30 years that there is an increase of 1.5 quality-adjusted life-years (QALYs). Additionally, HRT is highly cost-effective at $2438 per QALY gained. The totality of data converges to show a consistency between randomized trials and observational studies that when started in women at or near menopause and continued long-term, HRT decreases CHD and overall mortality compared with women who do not use HRT.

Chinese-language montreal cognitive assessment for cantonese or mandarin speakers: age, education, and gender effects.

The Montreal Cognitive Assessment Chinese-Language Los Angeles version (MoCA-ChLA) was developed and administered during an in-home interview to 1,192 participants (mean age 62.5 years, mean education 11.6 years) in a population-based Chinese American Eye Study (CHES) in Los Angeles. The MoCA-ChLA score (mean ± SD) was 23.8 ± 4.2 with little ceiling and no floor effects. The score increased with higher education, decreased with advancing age, and was not related to gender. Compared to the education 1-6 years group, the mean MoCA-ChLA score was 2.6 and 4.6 higher in the education 7-11 and 12-20 years groups, respectively. The Mandarin- (n = 612) and Cantonese- (n = 612) speaking subgroups performed comparably; Cronbach's alpha of the MoCA-ChLA score was 0.78 and 0.79 for these two groups, respectively. Item response theory analysis showed good discriminating power for executive function and memory. These properties support the MoCA-ChLA as a useful screening tool for aging and dementia studies for Mandarin or Cantonese speakers.

Hip fracture in postmenopausal women after cessation of hormone therapy: results from a prospective study in a large health management organization.

OBJECTIVE: Millions of women in the United States and across the globe abruptly discontinued postmenopausal hormone therapy (HT) after the initial Women's Health Initiative trial publication. Few data describing the effects of HT cessation on hip fracture incidence in the general population are available. We evaluated the impact of HT cessation on hip fracture incidence in a large cohort from the Southern California Kaiser Permanente health management organization. METHODS: In this longitudinal observational study, 80,955 postmenopausal women using HT as of July 2002 were followed up through December 2008. Data on HT use after July 2002, antiosteoporotic medication use, and occurrence of hip fracture were collected from the electronic medical record system. Bone mineral density (BMD) was assessed in 54,209 women once during the study period using the dual-energy x-ray absorptiometry scan. RESULTS: After 6.5 years of follow-up, age- and race-adjusted Cox proportional hazard models showed that women who discontinued HT were at 55% greater risk of hip fracture compared with those who continued using HT (hazard ratio, 1.55; 95% CI, 1.36-1.77). Hip fracture risk increased as early as 2 years after cessation of HT (hazard ratio, 1.52; 95% CI, 1.26-1.84), and the risk incrementally increased with longer duration of cessation (P for trend < 0.0001). Longer duration of HT cessation was linearly correlated with lower BMD (ß estimate [SE]) = -0.13 [0.003] T-score SD unit per year of HT cessation; P < 0.0001). CONCLUSIONS: Women who discontinued postmenopausal HT had significantly increased risk of hip fracture and lower BMD compared with women who continued taking HT. The protective association of HT with hip fracture disappeared within 2 years of cessation of HT. These results have public health implications with regard to morbidity and mortality from hip fracture.

Factors influencing driving status in an older Latino population.

OBJECTIVE: The study aims at examining factors associated with driving status and self-reported driving difficulty, with particular attention to vision and cognitive impairment. METHOD: This study uses cross-sectional data from 421 elderly Latino participants in the Los Angeles Latino Eye Study (LALES) along with cognitive screening, and comparison is by driving status (currently driving, used to drive, never drove) and self-reported difficulty driving among current drivers. RESULTS: Current drivers were more educated and reported better health.Those who never drove were less acculturated.Those who gave up driving had more visual impairment and lower scores on mental status testing. Self-reported difficulties among current drivers were associated with more health problems but not cognitive difficulties. DISCUSSION: Elderly Latinos have a lower driving rate than the general older population. There are significant differences between older Latinos who continue to drive versus those who never drove or have stopped driving. Poorer cognitive performance and poorer vision are associated with driving cessation.

Category fluency in a latino sample: associations with age, education, gender, and language.

The authors know of no published studies that have evaluated the effect of Spanish- versus English-language on category fluency within a sample of United States Latinos only. As part of a pilot study for the institution of a cognitive screening program in a cohort of Latinos, we assessed category fluency (fruits, vegetables, and "other" supermarket items) in a sample of 90 self-identified Latino community residents (aged 52-84, 0-18 years of education). The primary demographic correlates of category fluency were age and education. The decrement in naming of fruits with age was limited to the older old subjects (>age 70). Relatively younger old subjects (aged 61-70) did not differ from middle-aged subjects on category fluency. Gender showed little relationship to category naming. Persons naming in Spanish named significantly fewer 'other supermarket' items, but did not differ from English speakers in the more common fluency categories of fruits and vegetables. This analysis of category fluency in an ethnically homogenous sample with a wide range of formal education provided an evaluation of the effects of chosen language free of possible confounding by cultural differences, and also provided a more complete evaluation of the influence of education on category fluency.
