    Assessment of Hypertension Management and Outcomes at an Indianapolis Student-Run Free Clinic
    (Johns Hopkins University Press, 2017) Wahle, Benjamin; Meyer, Kathryn; Faller, Meredith; Kochhar, Komal; Sevilla, Javier
    Purpose. To characterize the quality of health care at student-run free clinics (SRFCs) by analyzing hypertension management and outcomes at the Indiana University Student Outreach Clinic (IUSOC). Methods. A retrospective review of medical records was conducted for hypertensive patients managed at IUSOC over 15 months (N = 64). Indiana University Student Outreach Clinic’s hypertension control rate was compared with National Health and Nutrition Examination Survey (NHANES) data. Results. Blood pressure control rates increased significantly over the study period. Indiana University Student Outreach Clinic’s control rate did not differ significantly with the NHANES national average, but was significantly greater than the NHANES group with no usual source of care. Similarly, IUSOC patients without insurance or with unknown insurance status had greater control rates than an uninsured NHANES group, but did not differ significantly from an insured NHANES group. Conclusions. Despite unfavorable demographic characteristics, records for patients with hypertension who used IUSOC as a regular provider of primary care compared favorably with national data.

    Distal and Proximal Influences on Self-Reported Oral Pain and Self-Rated Oral Health Status in Saudi Arabia: Retrospective Study Using a 2017 Nationwide Database
    (JMIR, 2024-12-20) Abogazalah, Naif; Yiannoutsos, Constantin; Soto-Rojas, Armando E.; Bindayeld, Naif; Yepes, Juan F.; Martinez Mier, Esperanza Angeles; Biostatistics and Health Data Science, Richard M. Fairbanks School of Public Health
    Background: Oral health significantly influences overall well-being, health care costs, and quality of life. In Saudi Arabia, the burden of oral diseases, such as dental caries and periodontal disease, has increased over recent decades, driven by various lifestyle changes. Objective: To explore the associations between proximal (direct) and distal (indirect) influences that affect oral pain (OP) and self-rated oral health (SROH) status in the Kingdom of Saudi Arabia (KSA) using an adapted conceptual framework. Methods: This retrospective cross-sectional study used data from a national health survey conducted in KSA in 2017. The sample included adults (N=29,274), adolescents (N=9910), and children (N=11,653). Sociodemographic data, health characteristics, and access to oral health services were considered distal influences, while frequency and type of dental visits, tooth brushing frequency, smoking, and consumption of sweets and soft drinks were considered proximal influences. Path analysis modeling was used to estimate the direct, indirect, and total effects of proximal and distal influences on OP and SROH status. Results: The mean age of adult respondents was 42.2 years; adolescents, 20.4 years; and children, 10.58 years. Despite OP reports from 39% of children, 48.5% of adolescents, and 47.1% of adults, over 87% across all groups rated their oral health as good, very good, or excellent. A higher frequency of tooth brushing showed a strong inverse relationship with OP and a positive correlation with SROH (P<.001). Frequent dental visits were positively associated with OP and negatively with SROH (P<.001). Sweet consumption increased OP in adolescents (β=0.033, P=.007) and negatively affected SROH in children (β=-0.086, P<.001), adolescents (β=-0.079, P<.001), and adults (β=-0.068, P<.001). Soft drink consumption, however, was associated with lower OP in adolescents (β=-0.034, P=.005) and improved SROH in adolescents (β=0.063, P<.001) and adults (β=0.068, P<.001). Smoking increased OP in adults (β=0.030, P<.001). Distal influences like higher education were directly linked to better SROH (β=0.046, P=.003) and less OP (indirectly through tooth brushing, β=-0.004, P<.001). For children, high household income correlated with less OP (β=-0.030, P=.02), but indirectly increased OP through other pathways (β=0.024, P=.003). Lack of access was associated with negative oral health measures (P<.001). Conclusions: Among the KSA population, OP and SROH were directly influenced by many proximal and distal influences that had direct, indirect, or combined influences on OP and SROH status.

    Risk Factors for Unplanned Higher-Level Re-Amputation and Mortality after Lower Extremity Amputation in Chronic Limb-Threatening Ischemia
    (MDPI, 2024-07-10) Guerra, Andres; Guo, Michelle; Boyd, Riley M.; Zakharevich, Marina; Hoel, Andrew W.; Vavra, Ashley K.; Chung, Jeanette W.; Ho, Karen J.; Surgery, School of Medicine
    Background: The factors associated with unplanned higher-level re-amputation (UHRA) and one-year mortality among patients with chronic limb-threatening ischemia (CLTI) after lower extremity amputation are poorly understood. Methods: This was a single-center retrospective study of patients who underwent amputations for CLTI between 2014 and 2017. Unadjusted bivariate analyses and adjusted odds ratios (AOR) from logistic regression models were used to assess associations between pre-amputation risk factors and outcomes (UHRA and one-year mortality). Results: We obtained data on 203 amputations from 182 patients (median age 65 years [interquartile range (IQR) 57, 75]; 70.7% males), including 118 (58.1%) toe, 20 (9.9%) transmetatarsal (TMA), 37 (18.2%) below-knee (BKA), and 28 (13.8%) amputations at or above the knee. Median follow-up was 285 days (IQR 62, 1348). Thirty-six limbs (17.7%) had a UHRA, and the majority of these (72.2%) were following index forefoot amputations. Risk factors for UHRA included non-ambulatory status (AOR 6.74, 95% confidence interval (CI) 1.74–26.18; p < 0.10) and toe pressure < 30 mm Hg (AOR 4.89, 95% CI 1.52–15.78; p < 0.01). One-year mortality was 17.2% (n = 32), and risk factors included coronary artery disease (AOR 3.93, 95% CI 1.56–9.87; p < 0.05), congestive heart failure (AOR 4.90, 95% CI 1.96–12.29; p = 0.001), end-stage renal disease (AOR 7.54, 95% CI 3.10–18.34; p < 0.001), and non-independent ambulation (AOR 4.31, 95% CI 1.20–15.49; p = 0.03). Male sex was associated with a reduced odds of death at 1 year (AOR 0.37, 95% CI 0.15–0.89; p < 0.05). UHRA was not associated with one-year mortality. Conclusions: Rates of UHRA after toe amputations and TMA are high despite revascularization and one-year mortality is high among patients with CLTI requiring amputation.
