Assessing Community Needs Among Spanish-Speaking Patients in a Free Clinic Setting.

INTRODUCTION AND OBJECTIVES: La Clínica Latina is a free clinic that strives to meet the healthcare needs of the Spanish-speaking population of Franklin County, Ohio, including metropolitan Columbus. As a student-run free clinic, care is provided each week by volunteer medical students and resident physicians under the administrative leadership of the medical student board and clinical supervision of licensed physicians. Patients served by the clinic have a multitude of chronic health conditions, which are managed by clinic volunteers through the delivery of over 1500 appointments per year. In order to better serve the rapidly growing patient population, this study describes the delivery and results of an assessment aimed at understanding the needs that are being met sufficiently at the clinic and what pitfalls still exist in the clinic's provision of care. METHODS: By delivering a survey inquiring about the experiences of patients at La Clínica Latina, clinic workflow can be optimized for the provision of patient-centered care. RESULTS: Insights collected from a convenience sample of 30 patients demonstrate mobile phone use as the primary mode of communication with clinic volunteers, previously under-appreciated musculoskeletal health concerns, longer than desired wait times after check-in, and variable experiences of health literacy by patient gender. CONCLUSION: By addressing each of these insights in updates to clinic workflow, La Clínica Latina may prove to become an even more useful resource to the region's growing Hispanic population.

Comparative Effectiveness of Hybrid Closed-Loop Automated Insulin Delivery Systems Among Patients with Type 1 Diabetes.

BACKGROUND: Clinical trials have demonstrated the efficacy and safety of hybrid closed-loop (HCL) systems, yet few studies have compared outcomes in the real-world setting. METHOD: This retrospective study analyzed patients from an academic endocrinology practice between January 1, 2018, and November 18, 2022. The inclusion criteria were diagnosis code for type I diabetes (T1D), >18 years of age, new to any HCL system [Medtronic 670G/770G (MT), Tandem Control IQ (CIQ), or Omnipod 5 (OP5)], and availability of a pump download within three months. The outcomes included %time in range (TIR) of 70 to 180 mg/dL, %time below range (TBR) <70 mg/dL at 90 days, and HbA1c for 91 to 180 days. RESULT: Of the 176 participants, 47 were MT, 74 CIQ, and 55 OP5. Median (25%, 75%) change in HbA1c was -0.1 (-0.8, 0.3), -0.6 (-1.1, -0.15), and -0.55 (-0.98, 0)% for MT, CIQ, and OP5, respectively, (P = .04). TIR was 70 (57, 76), 67 (59, 75), and 68 (60, 76)% (P = .95) at 90 days while TBR was 2 (1, 3), 1 (0, 2), and 1 (0, 1)%, respectively, (P = .002). The %time in automated delivery was associated with TIR and change in HbA1c. After controlling other factors including %time in automated delivery, HCL type was not an independent predictor of change in HbA1c nor TIR but remained a significant predictor of TBR. CONCLUSION: There were significant reductions in HbA1c in CIQ and OP5. TIR was similar across pumps, but TBR was highest with MT. The %time in automated delivery likely explains differences in change in HbA1c but not TBR between HCL systems.

Effect of Lower Extremity Nerve Decompression in Patients With Painful Diabetic Peripheral Neuropathy: The Diabetic Neuropathy Nerve Decompression Randomized, Observation Group and Placebo Surgery-Controlled Clinical Trial.

OBJECTIVE: To evaluate the effect of nerve decompression on pain in patients with lower extremity painful diabetic peripheral neuropathy (DPN). BACKGROUND: Currently, no treatment provides lasting relief for patients with DPN. The benefits of nerve decompression remain inconclusive. METHODS: This double-blinded, observation and same-patient sham surgery-controlled randomized trial enrolled patients aged 18 to 80 years with lower extremity painful DPN who failed 1 year of medical treatment. Patients were randomized to nerve decompression or observation group (2:1). Decompression-group patients were further randomized and blinded to nerve decompression in either the right or left leg and sham surgery in the opposite leg. Pain (11-point Likert score) was compared between decompression and observation groups and between decompressed versus sham legs at 12 and 56 months. RESULTS: Of 2987 screened patients, 78 were randomized. At 12 months, compared with controls (n=37), both the right-decompression group (n=22) and left-decompression group (n=18) reported lower pain (mean difference for both: -4.46; 95% CI: -6.34 to -2.58 and -6.48 to -2.45, respectively; P < 0.0001). Decompressed and sham legs equally improved. At 56 months, compared with controls (n=m 14), pain was lower in both the right-decompression group (n=20; mean difference: -7.65; 95% CI: -9.87 to -5.44; P < 0.0001) and left-decompression group (n=16; mean difference: -7.26; 95% CI: -9.60 to -4.91; P < 0.0001). The mean pain score was lower in decompressed versus sham legs (mean difference: 1.57 95% CI: 0.46 to 2.67; P =0.0002). CONCLUSIONS: Although nerve decompression was associated with reduced pain, the benefit of surgical decompression needs further investigation as a placebo effect may be responsible for part or all of these effects.

Applying National Diabetic Care Standards for the Management of a Hispanic Population Attending a Free Clinic.

BACKGROUND: National quality measures set goals for diabetes management. Hispanic populations are higher risk for diabetes and associated complications, especially low-income communities. Research suggests free clinics provide suboptimal diabetes management. Our quality improvement project aims to improve diabetes management in the Hispanic free clinic population. METHODS: Clínica Latina's volunteer medical students and physicians serve predominantly uninsured Spanish-speaking patients. Established diabetes patients that attended clinic during the study were included. Data was collected regarding patients' diabetes care for two months, then analyzed compared to quality metrics. We implemented paper checklists and electronic medical record (EMR) smart phrases for volunteers to utilize in managing diabetes. RESULTS: 32 patients were included in the study. At baseline, 78% had an A1C check in the past 3 months, 81% were on a statin. In the past year, 81% had a lipid panel, 19% had an eye exam, 63% had a diabetic foot exam, 53% had a urine microalbumin-creatinine screening. After interventions, 97% had an A1C check, 93% were on a statin, 91% had a lipid panel, 31% had an eye exam, 75% had a foot exam, 63% had a urine microalbumin-creatinine. Patients with an LDL < 100 increased from 62 to 66%. The mean A1C did not statistically significantly change. Volunteer smart phrase utilization increased from 37 to 59.1%. CONCLUSION: We implemented a checklist and EMR smart phrase to optimize diabetes management in a student-run Hispanic free clinic, which improved quality metrics. Low-resource clinics serving Spanish-speaking populations may benefit from similar interventions to improve diabetic care.

The Impact of a Diabetes Transitions of Care Clinic on Hospital Utilization and Patient Care.

BACKGROUND: There is currently limited guidance from the American Diabetes Association regarding transitions of care for patients with diabetes. OBJECTIVE: This study's aim was to determine the impact of a diabetes-specific transitions of care clinic (TOCC) on hospital utilization and patient outcomes in recently discharged patients with diabetes. METHODS: This retrospective study evaluated patients seen by TOCC as compared with similar patients discharged from the study institution the year prior. The primary outcome was a composite of the number of unique patients with readmissions/emergency department (ED) visits within 30 days of discharge. Secondary outcomes included a subcomponent analysis of readmissions/ED visits, index hospital length of stay (LOS), and to describe clinical interventions made in clinic. This study was approved by the institutional review board of the Office of Responsible Research Practice at the Ohio State University Wexner Medical Center. RESULTS: There were 165 patients in the TOCC group and 157 in the control group based on the matching criteria. There was a statistically significant decrease in the primary outcome in the TOCC group versus the control group (18% vs 36%, P < 0.001). In evaluation of its subcomponents, there was a statically significant decrease in patients with readmissions (11% vs 26%, P < 0.001) but not ED visits (10% vs 17%, P = 0.096). The LOS for the TOCC group was shorter at 4 days versus 5 days in the control group (P = 0.055). CONCLUSIONS AND RELEVANCE: The implementation of a diabetes-specific TOCC can decrease both readmissions and ED visits and may impact hospital LOS. In addition, a TOCC can be used to identify gaps in preventive care. The results from this study may help support the creation of similar TOCC at other institutions.

COVID-19 Vaccination Rates and Vaccine Hesitancy Among Spanish-Speaking Free Clinic Patients.

We sought to assess COVID-19 vaccination rates, as well as attitudes and beliefs towards the vaccine, of patients in a Spanish-speaking student-run free clinic in Columbus, Ohio. A cross-sectional study was performed. Surveys were distributed to all individuals over 18 years who presented to La Clínica Latina between July, 2022 and September, 2022. A convenience sample was used: patients in the waiting room and their accompanying family members or friends were invited to participate. Subjects were excluded if under the age of 18 or over the age of 75, or if non-Spanish speaking. Of the 158 individuals who agreed to participate in our study, 146 responded to the question regarding vaccination status, revealing 90.4% of respondents had received a COVID-19 vaccination. Most respondents learned about the vaccine from social media (26.4%) or television (22.7%). The majority of participants sought answers to questions surrounding the vaccine by asking their doctor (49.1%). The most common reason among unvaccinated participants for not undergoing vaccination was fear of an adverse reaction to the vaccine (n = 11). We found that a large proportion (90.4%) of individuals seeking care at a Spanish-speaking free clinic were vaccinated against COVID-19. Our study also provides perspective on the means of health knowledge acquisition and behaviors in this predominantly Latinx patient population in central Ohio. We can utilize our results to optimize and tailor clinic services and initiatives for COVID-19 boosters to meet the needs of this community.

Hypothyroidism Prevalence in the United States: A Retrospective Study Combining National Health and Nutrition Examination Survey and Claims Data, 2009-2019.

Previous estimates determined prevalence of hypothyroidism (HT) to be 4.6% of the US population. This study aimed to update estimates of HT prevalence in the United States by retrospective analysis of 2 datasets. Data on HT type (overt or subclinical HT) and treatment were collected from the 2009-2010 and 2011-2012 National Health and Nutrition Examination Survey (NHANES) cycles. From the Optum administrative claims database, medical and pharmacy claims were collected between January 1, 2012, and December 31, 2019. Patients were defined as having HT if, per given year, they had >1 prescription for HT treatment, >1 claim indicating an HT diagnosis, or thyroid-stimulating hormone levels >4.0 mIU/L (NHANES arm). For both studies, treatment was defined as any evidence of synthetic or natural thyroid hormone replacement, identified by pharmacy claims or patient surveys. Data are reported as percentage of patients with HT and treatments received. Between 2009 and 2012, HT prevalence remained around 9.6% of the US population. The administrative claims dataset showed that HT prevalence grew from 9.5% in 2012 to 11.7% in 2019 and that >78% of patients received thyroxine (T4) monotherapy. Similarly, the NHANES dataset showed that T4 replacement therapy was the most common treatment for HT. From 2012-2019, patients with untreated HT grew from 11.8% to 14.4%. The prevalence of HT in the United States has steadily increased since 2009. Likewise, the percentage of hypothyroid-diagnosed patients not receiving treatment also increased, suggesting that the increased prevalence may be due to increased cases of subclinical HT.

Predictors of change in hypoglycemia unawareness among patients with type 1 diabetes.

AIMS: To analyse predictors of hypoglycemia unawareness (HU) and improvement in Clarke score in clinical practice. MATERIALS AND METHODS: We retrospectively identified patients with type 1 diabetes (T1D) at an academic T1D clinic who completed HU surveys 6-12 months apart. HU (Clarke score ≥4) and improvement in Clarke score (decrease by ≥1 point or more clinically relevant ≥2 point) were assessed in univariable relationships and using multivariable logistic regression. RESULTS: Of the 300 participants, median diabetes duration was 19 years, 47 had HU at baseline, and 91 had an improvement by 1 point while 21 had an improvement by 2 points. Patients with baseline Clarke score ≥4 who had ≥1 or ≥2 point improvement had lower filtration rate (eGFR) than those who did not. After adjustment for other variables, gender (male OR 0.33, 95% CI 0.15, 0.74), log diabetes duration (OR 6.40, 95% CI 2.84, 14.5), and eGFR <60 ml/min/1.73 m2 (5.56, 95% CI 1.98, 15.6) were independent predictors of baseline HU. Continuous glucose monitoring use (OR 2.04, 95% CI 1.20, 3.48) and log diabetes duration (OR 1.78, 95% CI 1.22, 2.60) were independent predictors of 1 point improvement and eGFR <60 ml/min/1.73 m2 (OR 10.5, 95% CI 3.64, 30.0) and an education visit (OR 2.64, 95% CI 1.01, 6.89) were independent predictors of 2 point improvement in Clarke score. CONCLUSIONS: Diabetes duration, gender, and eGFR were independent predictors of HU. Improvement in Clarke score is possible in patients with long-standing T1D, underscoring the need for additional study.

Interferon gamma mediates the reduction of adipose tissue regulatory T cells in human obesity.

Decreased adipose tissue regulatory T cells contribute to insulin resistance in obese mice, however, little is known about the mechanisms regulating adipose tissue regulatory T cells numbers in humans. Here we obtain adipose tissue from obese and lean volunteers. Regulatory T cell abundance is lower in obese vs. lean visceral and subcutaneous adipose tissue and associates with reduced insulin sensitivity and altered adipocyte metabolic gene expression. Regulatory T cells numbers decline following high-fat diet induction in lean volunteers. We see alteration in major histocompatibility complex II pathway in adipocytes from obese patients and after high fat ingestion, which increases T helper 1 cell numbers and decreases regulatory T cell differentiation. We also observe increased expression of inhibitory co-receptors including programmed cell death protein 1 and OX40 in visceral adipose tissue regulatory T cells from patients with obesity. In human obesity, these global effects of interferon gamma to reduce regulatory T cells and diminish their function appear to instigate adipose inflammation and suppress adipocyte metabolism, leading to insulin resistance.

Influence of Literacy, Self-Efficacy, and Social Support on Diabetes-Related Outcomes Following Hospital Discharge.

Objective: To evaluate the relationship between health literacy, social support, and self-efficacy as predictors of change in A1c and readmission among hospitalized patients with type 2 diabetes (T2D). Methods: This is a secondary analysis of patients with T2D (A1c >8.5%) enrolled in a randomized trial in which health literacy (Newest Vital Sign), social support (Multidimensional Scale of Perceived Social Support), and empowerment (Diabetes Empowerment Scale-Short Form) was assessed at baseline. Multivariable models evaluated whether these concepts were associated with A1c reduction at 12 weeks (absolute change, % with >1% reduction, % reaching individualized target) and readmission (14 and 30 days). Results: A1c (N=108) decreased >1% in 60%, while individualized A1c target was achieved in 31%. After adjustment for baseline A1c and potential confounders, health literacy was associated with significant reduction in A1c (Estimate -0.21, 95% CI -0.40, -0.01, p=0.041) and >1% decrease in A1c (OR 1.37, 95% CI 1.08, 1.73, p=0.009). However, higher social support was associated with greater adjusted odds of reaching the individualized A1c target (OR 1.63, 95% CI 1.04, 2.55, p=0.32). Both higher empowerment (OR 0.23, 95% CI 0.08, 0.64, p=0.005) and social support (OR 0.57, 95% CI 0.36, 0.91, p=0.018) were associated with fewer readmissions by 14 days, but not 30 days. Conclusion: The study indicates that health literacy and social support may be important predictors of A1c reduction post-discharge among hospitalized patients with T2D. Social support and diabetes self-management skills should be addressed and early follow-up may be critical for avoiding readmissions. Clinical Trial: NCT03455985.
