Associations among claims-based care fragmentation, self-reported gaps in care coordination, and self-reported adverse events.

BACKGROUND: Fragmentation of care (that is, the use of multiple ambulatory providers without a dominant provider) may increase the risk of gaps in communication among providers. However, it is unclear whether people with fragmented care (as measured in claims) perceive more gaps in communication among their providers. It is also unclear whether people who perceive gaps in communication experience them as clinically significant (that is, whether they experience adverse events that they attribute to poor coordination). METHODS: We conducted a longitudinal study using data from the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study, including a survey on perceptions of healthcare (2017-2018) and linked fee-for-service Medicare claims (for the 12 months prior to the survey) (N = 4,296). We estimated correlation coefficients to determine associations between claims-based and self-reported numbers of ambulatory visits and ambulatory providers. We then used logistic regression to determine associations between claims-based fragmentation (measured with the reversed Bice-Boxerman Index [rBBI]) and self-reported gaps in care coordination and, separately, between claims-based fragmentation and self-reported adverse events that the respondent attributed to poor coordination. RESULTS: The correlation coefficient between claims-based and self-report was 0.37 for the number of visits and 0.38 for the number of providers (p < 0.0001 for each). Individuals with high fragmentation by claims (rBBI ≥ 0.85) had a 23% increased adjusted odds of reporting any gap in care coordination (95% CI 3%, 48%) and, separately, a 61% increased adjusted odds of reporting an adverse event that they attributed to poor coordination (95% CI 11%, 134%). CONCLUSIONS: Medicare beneficiaries with claims-based fragmentation also report gaps in communication among their providers. Moreover, these gaps appear to be clinically significant, with beneficiaries reporting adverse events that they attribute to poor coordination.

Health Status, Persistent Symptoms, and Effort Intolerance One Year After Acute COVID-19 Infection.

BACKGROUND: The long-term prevalence and risk factors for post-acute COVID-19 sequelae (PASC) are not well described and may have important implications for unvaccinated populations and policy makers. OBJECTIVE: To assess health status, persistent symptoms, and effort tolerance approximately 1 year after COVID-19 infection DESIGN: Retrospective observational cohort study using surveys and clinical data PARTICIPANTS: Survey respondents who were survivors of acute COVID-19 infection requiring Emergency Department presentation or hospitalization between March 3 and May 15, 2020. MAIN MEASURE(S): Self-reported health status, persistent symptoms, and effort tolerance KEY RESULTS: The 530 respondents (median time between hospital presentation and survey 332 days [IQR 325-344]) had mean age 59.2±16.3 years, 44.5% were female and 70.8% were non-White. Of these, 41.5% reported worse health compared to a year prior, 44.2% reported persistent symptoms, 36.2% reported limitations in lifting/carrying groceries, 35.5% reported limitations climbing one flight of stairs, 38.1% reported limitations bending/kneeling/stooping, and 22.1% reported limitations walking one block. Even those without high-risk comorbid conditions and those seen only in the Emergency Department (but not hospitalized) experienced significant deterioration in health, persistent symptoms, and limitations in effort tolerance. Women (adjusted relative risk ratio [aRRR] 1.26, 95% CI 1.01-1.56), those requiring mechanical ventilation (aRRR 1.48, 1.02-2.14), and people with HIV (aRRR 1.75, 1.14-2.69) were significantly more likely to report persistent symptoms. Age and other risk factors for more severe COVID-19 illness were not associated with increased risk of PASC. CONCLUSIONS: PASC may be extraordinarily common 1 year after COVID-19, and these symptoms are sufficiently severe to impact the daily exercise tolerance of patients. PASC symptoms are broadly distributed, are not limited to one specific patient group, and appear to be unrelated to age. These data have implications for vaccine hesitant individuals, policy makers, and physicians managing the emerging longer-term yet unknown impact of the COVID-19 pandemic.

An Evaluation of a Perinatal Education and Support Program to Increase Breastfeeding in a Chinese American Community.

INTRODUCTION: In 2015, a community health center implemented a multipronged, Chinese language, health education initiative to increase breastfeeding. Perinatal education, hospital visits after delivery, and postpartum support were implemented to provide informational and emotional support. This study evaluates the impact of the breastfeeding program for Chinese American women. METHODS: This is a quasi-experimental study to assess the change in any and exclusive breastfeeding at 4-6 weeks postpartum. A difference-in-differences regression analysis was used to determine change in breastfeeding attributable to the program at an intervention site after adjusting for change in a control site during the same period. Change in breastfeeding was also examined by sociodemographic characteristics. RESULTS: A total of 1475 women who received perinatal care at two community center sites in 2014 and 2016 were included in the study. Within the women who received the intervention, any breastfeeding increased by 24 percentage points to 71% and exclusive breastfeeding increased by 13 percentage points to 27%. After adjusting for the change in the control group during the same period, the increases in any and exclusive breastfeeding attributable to the program were 17 (p < 0.01) and 9 percentage points (p < 0.05), respectively. Primiparous women and those who have been in the US longer than 5 years experienced the highest increase in any breastfeeding from the program. Exclusive breastfeeding was most improved in those with non-Medicaid insurance. CONCLUSIONS: A bilingual and bicultural breastfeeding program incorporated into routine pregnancy care at an intervention site experienced increases in both any and exclusive breastfeeding, even after adjusting for changes in breastfeeding in a control group. SIGNIFICANCE STATEMENT: What is known on this subject? Chinese Americans are the least likely to breastfeed among all ethnicities in New York City. Cultural and language barriers plus the lack of Chinese language resources contribute to low breastfeeding rates. What this study adds? A bilingual and bicultural breastfeeding program of perinatal education and postpartum support incorporated into routine pregnancy care increased both any and exclusive breastfeeding in a Chinese American population. Increase in any breastfeeding was the greatest in primiparous women and those who had been in the US for a longer time and increase in exclusive breastfeeding was greatest in women not using Medicaid insurance.

Measuring overweight and obesity in Chinese American children using US, international and ethnic-specific growth charts.

OBJECTIVE: The aim is to determine the disparity between the overweight and obesity prevalence of Chinese American school-aged children and adolescents as measured by the Centers for Disease Control and Prevention (CDC) growth reference and the prevalence as measured by international and ethnic-specific-growth references. DESIGN: This retrospective, cross-sectional study measured overweight and obesity prevalence among a paediatric population using the CDC, International Obesity Task Force (IOTF), World Health Organization (WHO) and an ethnic Chinese growth curve. SETTING: A community health centre in New York City, USA. PARTICIPANTS: Chinese American children aged 6-17 years in 2017 (N 9160). RESULTS: The overweight prevalence was 24 % (CDC), 23 % (IOTF), 30 % (WHO) and 31 % (China). The obesity prevalence was 10 % (CDC), 5 % (IOTF), 10 % (WHO) and 10 % (China). When disaggregated by age and sex, the difference was the most prominent in girls; using the China reference compared with using the CDC reference almost doubles the overweight prevalence (school-aged: 31 v. 17 %, P < 0·001, adolescent: 27 v. 14 %, P < 0·001) and the obesity prevalence (school-aged: 11 v. 5 %, P < 0·001, adolescent: 7 v. 4 %, P < 0·001). CONCLUSIONS: Use of the CDC reference compared with the Chinese ethnic-specific reference results in lower overweight and obesity prevalence in Chinese American girls. Almost half of the girls who were overweight and half of the girls who were obese were not identified using the CDC reference. Using ethnic-specific references or ethnic-specific cut-points may help improve overweight identification for Chinese American children.

Reductions in renin-angiotensin system inhibitors following hospitalization for heart failure.

AIMS: Limited data are available that evaluate the efficacy of renin-angiotensin system inhibitor (RASI) dose-reduction in older adults with heart failure with reduced ejection fraction following a heart failure hospitalization. METHODS AND RESULTS: We examined a 5% random sample of Medicare beneficiaries with prescription coverage who were discharged to home following a hospitalization for heart failure with reduced ejection fraction between 1 January 2007 and 30 June 2018 and were treated with RASI prior to hospitalization. We classified patients into three mutually exclusive groups based on RASI dosage before (prescription fills up to 90 days prior to) and after a hospitalization (prescription fills up to 365 days that were most proximate to the discharge date as possible)-same/increased dose, dose-reduction, and discontinuation. We examined associations between RASI prescribing patterns and outcomes (mortality and all-cause readmission at 30 days and 1 year) using Cox proportional hazards models. Among 12 794 unique older adults, 36.8% experienced a RASI reduction following their hospitalization for HFrEF-15.7% had a dose-reduction and 21.1% had a discontinuation. Neither dose-reduction nor discontinuation was associated with 30-day mortality. Discontinuation was associated 1-year mortality, 30-day all-cause readmission, and 1-year all-cause readmission, whereas dose-reduction was not. CONCLUSION: RASI dose-reduction occurs in 1 out of 7 HF hospitalizations. In contrast to RASI discontinuation, RASI dose-reduction was not associated with adverse short or long-term outcomes. These findings indicate that RASI dose-reduction is preferred over RASI discontinuation in selected situations where RASI reduction is needed.

Association of Healthy Lifestyle and Incident Polypharmacy.

BACKGROUND: Polypharmacy, commonly defined as taking ≥5 medications, is an undesirable state associated with lower quality of life. Strategies to prevent polypharmacy may be an important priority for patients. We sought to examine the association of healthy lifestyle, a modifiable risk factor, with incident polypharmacy. METHODS: We performed a secondary analysis of the REasons for Geographic and Racial Differences in Stroke (REGARDS) cohort study, including 15,478 adults aged ≥45 years without polypharmacy at baseline. The primary exposure was healthy lifestyle at baseline as measured by the Healthy Behavior Score (HBS), a cumulative assessment of diet, exercise frequency, tobacco smoking, and sedentary time. HBS ranges from 0-8, whereby 0-2 indicates low HBS, 3-5 indicates moderate HBS, and 6-8 indicates high HBS. We used multinomial logistic regression to examine the association between HBS and incident polypharmacy, survival without polypharmacy, and death. RESULTS: Higher HBS (i.e., healthier lifestyle) was inversely associated with incident polypharmacy after adjusting for sociodemographic and baseline health variables. Compared with participants with low HBS, those with moderate HBS had lower odds of incident polypharmacy (odds ratio [OR] 0.85; 95% confidence interval [CI], 0.73-0.98) and lower odds of dying (OR 0.74; 95% CI, 0.65-0.83). Participants with high HBS had even lower odds of both incident polypharmacy (OR 0.75; 95% CI, 0.64-0.88) and death (OR 0.62; 95% CI, 0.54-0.70). There was an interaction for age, where the association between HBS and incident polypharmacy was most pronounced for participants aged ≤65 years. CONCLUSIONS: Healthier lifestyle was associated with lower risk for incident polypharmacy.

Brain fog in long COVID limits function and health status, independently of hospital severity and preexisting conditions.

Importance: The U.S. government has named post-acute sequelae of COVID-19 (longCOVID) as influential on disability rates. We previously showed that COVID-19 carries a medical/functional burden at 1 year, and that age and other risk factors of severe COVID-19 were not associated with increased longCOVID risk. Long-term longCOVID brain fog (BF) prevalence, risk factors and associated medical/functional factors are poorly understood, especially after mild SARS-CoV-2 infection. Methods: A retrospective observational cohort study was conducted at an urban tertiary-care hospital. Of 1,032 acute COVID-19 survivors from March 3-May 15, 2020, 633 were called, 530 responded (59.2 ± 16.3 years, 44.5% female, 51.5% non-White) about BF prevalence, other longCOVID, post-acute ED/hospital utilization, perceived health/social network, effort tolerance, disability. Results: At approximately 1-year, 31.9% (n = 169) experienced BF. Acute COVID-19 severity, age, and premorbid cardiopulmonary comorbidities did not differ between those with/without BF at 1 year. Patients with respiratory longCOVID had 54% higher risk of BF than those without respiratory longCOVID. BF associated with sleep disturbance (63% with BF vs.29% without BF, p < 0.0001), shortness of breath (46% vs.18%, p < 0.0001), weakness (49% vs.22%, p < 0.0001), dysosmia/dysgeusia (12% vs.5%, p < 0.004), activity limitations (p < 0.001), disability/leave (11% vs.3%, p < 0.0001), worsened perceived health since acute COVID-19 (66% vs.30%, p < 0.001) and social isolation (40% vs.29%, p < 0.02), despite no differences in premorbid comorbidities and age. Conclusions and relevance: A year after COVID-19 infection, BF persists in a third of patients. COVID-19 severity is not a predictive risk factor. BF associates with other longCOVID and independently associates with persistent debility.

Physician Perspectives on the Use of Beta Blockers in Heart Failure With Preserved Ejection Fraction.

ß-blockers are commonly used in heart failure with preserved ejection fraction (HFpEF), even in the absence of a compelling indication and despite the potential to cause harm. Identifying reasons for ß-blocker prescription in HFpEF could permit the development of strategies to reduce unnecessary use and potentially improve medication prescribing patterns in this vulnerable population. We administered an online survey regarding ß-blocker prescribing behavior to physicians trained in internal medicine or geriatrics (noncardiology physicians) and to cardiologists at 2 large academic medical centers. The survey assessed the reasons for ß-blocker initiation, agreement regarding initiation and/or continuation of ß-blockers by another clinician, and deprescribing behavior. The response rate was 28.2% (n = 231). Among respondents, 68.2% reported initiating ß-blockers in patients with HFpEF. The most common reason for initiating a ß-blocker was for treatment of an atrial arrhythmia. Notably, 23.7% of physicians reported initiating a ß-blocker without an evidence-based indication. When a ß-blocker was considered not necessary, 40.1% of physicians reported they were rarely or never willing to deprescribe. The most common reason for not deprescribing a ß-blocker when the physician felt that a ß-blocker was unnecessary was the concern about interfering with another physicians' treatment plan (76.6%). In conclusion, a significant proportion of noncardiology physicians and cardiologists report prescribing ß-blockers to patients with HFpEF, even when evidence-based indications are absent, and rarely deprescribe ß-blockers in these scenarios.

Weight Status Change in Chinese American Children over a Ten-Year Period: Retrospective Study of a Primary Care Pediatric Population.

Weight change from childhood to adolescence has been understudied in Asian Americans. Known studies lack disaggregation by Asian subgroups. This retrospective study assessed the weight status change in 1500 Chinese American children aged 5−11 years from an urban primary care health center between 2007 and 2017. Weight status was categorized using the 2000 CDC growth charts into "underweight/normal weight" and "overweight/obese." The overweight/obesity prevalence in 2007 and 2017 were determined. McNemar's test and logistic regression were performed. The prevalence of overweight/obesity decreased from 29.9% in 2007 to 18.6% in 2017. Children who were overweight/obese at 5−11 years had 10.3 increased odds of staying overweight/obese over time (95% CI = 7.6−14.0, p < 0.001) compared to their underweight/normal weight counterparts. Of the children who were overweight/obese in 2007, 45.7% remained overweight/obese ten years later. Childhood overweight/obesity strongly predicts adult overweight/obesity in Chinese Americans. Targeted education and intervention are warranted to prevent adult obesity.

Development of a Practice-based Community Outreach Intervention to Prevent Inequities in COVID-19 Vaccinations.

Despite disproportionately higher rates of morbidity and mortality from COVID-19 among Black and Hispanic adults in the United States, ethnoracial disparities in vaccination rates emerged rapidly. The objective of this quality improvement study was to rapidly develop and implement an equity-focused community outreach intervention that facilitated COVID-19 vaccine appointments. Using the Plan-Do-Study-Act model, this multipronged, primary care-based outreach intervention developed call/recall systems that addressed vaccine hesitancy and facilitated real-time vaccine scheduling. Through 5058 calls to 2794 patients, 1519 patients were successfully reached. Of the 750 patients eligible for vaccine scheduling, 129 (17.2%) had a vaccine appointment scheduled by the caller and 72 (9.6%) indicated a plan to self-schedule. Low confidence in the vaccine was the most cited reason for declining assistance with a vaccine appointment. Primary care practices may wish to consider introducing similar outreach interventions in the future to address ethnoracial inequities in vaccination distribution.

Hyperglycemia in Acute COVID-19 is Characterized by Adipose Tissue Dysfunction and Insulin Resistance.

COVID-19 has proven to be a metabolic disease resulting in adverse outcomes in individuals with diabetes or obesity. Patients infected with SARS-CoV-2 and hyperglycemia suffer from longer hospital stays, higher risk of developing acute respiratory distress syndrome (ARDS), and increased mortality compared to those who do not develop hyperglycemia. Nevertheless, the pathophysiological mechanism(s) of hyperglycemia in COVID-19 remains poorly characterized. Here we show that insulin resistance rather than pancreatic beta cell failure is the prevalent cause of hyperglycemia in COVID-19 patients with ARDS, independent of glucocorticoid treatment. A screen of protein hormones that regulate glucose homeostasis reveals that the insulin sensitizing adipokine adiponectin is reduced in hyperglycemic COVID-19 patients. Hamsters infected with SARS-CoV-2 also have diminished expression of adiponectin. Together these data suggest that adipose tissue dysfunction may be a driver of insulin resistance and adverse outcomes in acute COVID-19.

Hyperglycemia in acute COVID-19 is characterized by insulin resistance and adipose tissue infectivity by SARS-CoV-2.

Individuals infected with SARS-CoV-2 who also display hyperglycemia suffer from longer hospital stays, higher risk of developing acute respiratory distress syndrome (ARDS), and increased mortality. Nevertheless, the pathophysiological mechanism of hyperglycemia in COVID-19 remains poorly characterized. Here, we show that hyperglycemia is similarly prevalent among patients with ARDS independent of COVID-19 status. Yet among patients with ARDS and COVID-19, insulin resistance is the prevalent cause of hyperglycemia, independent of glucocorticoid treatment, which is unlike patients with ARDS but without COVID-19, where pancreatic beta cell failure predominates. A screen of glucoregulatory hormones revealed lower levels of adiponectin in patients with COVID-19. Hamsters infected with SARS-CoV-2 demonstrated a strong antiviral gene expression program in the adipose tissue and diminished expression of adiponectin. Moreover, we show that SARS-CoV-2 can infect adipocytes. Together these data suggest that SARS-CoV-2 may trigger adipose tissue dysfunction to drive insulin resistance and adverse outcomes in acute COVID-19.

The Association of Grandparent Care with Childhood Overweight and Obesity in Chinese American Families.

BACKGROUND: Grandparents are often the caretakers of children in Chinese American families. Studies have shown that Chinese grandparents underestimate the weight of their grandchildren and associate food with increased height and strength. This study examines the association of grandparental care with weight status in Chinese American children and adolescents. METHODS: This is a cross-sectional study of 12,029 Chinese American pediatric patients ages 2-19 at a community health center in New York City in 2015. Grandparental care was defined as child care provided by at least one grandparent. Multivariable logistic regression was conducted to assess for association between having a grandparent caretaker and weight status in the age groups 2-5, 6-11, and 12-19 while adjusting for sex, place of birth, neighborhood poverty, and two-parent households. RESULTS: Approximately 12% of Chinese American children in this population had a grandparent caretaker. Children and adolescents with grandparent caretakers are more likely to be overweight than their counterparts with no grandparent caretakers at ages 6-11 (odds ratio [OR]: 1.48; 95% confidence interval [CI]: 1.23-1.79) and ages 12-19 (OR: 1.54; 95% CI: 1.18-2.02). No association was found between grandparental care and overweight in ages 2-5 nor with obesity in any age group. CONCLUSIONS: Grandparental care is associated with the weight of school-age children and adolescents. Targeted education on appropriate nutrition for the child's age is needed for grandparents who take care of children.

Update on Chinese American Childhood Obesity Prevalence in New York City.

Prevalence of overweight and obesity was measured in 12,275 Chinese American children and adolescents, ages 2-19, who were patients at a large federally qualified health center in 2015. Demographic characteristics sex, age, and birthplace were further stratified to explore disaggregated prevalence. Comparison of this 2015 cohort to an ethnically similar study cohort from the same health center in 2004 showed that the overall prevalence in overweight and obesity dropped to 21% from previously recorded 24%. US Born school-aged males continue to have the highest prevalence of overweight and obesity at 36%. School-aged children have higher odds of being overweight or obese (OR 1.61, P < 0.001; OR 1.99, P < 0.001) compared to adolescents. Although the foreign-born females had the lowest prevalence of overweight and obesity (12%), they were the only group in 2015 to have increased prevalence in overweight and obesity since 2004 (by 5.8%).

Patient Navigation Program for Colorectal Cancer Screening in Chinese Americans at an Urban Community Health Center: Lessons Learned.

Colorectal cancer is a major cause of cancer-related deaths in Asian Americans, yet Asian Americans have the lowest colorectal cancer screening rates in New York City. The Charles B. Wang Community Health Center implemented a patient navigation program to increase colorectal cancer screening. This report describes the lessons learned from the program.
