Incidence and Cost of Ankle Sprains in United States Emergency Departments

Background: Ankle sprains represent a common injury in emergency departments, but little is known about common complications, procedures, and charges associated with ankle sprains in emergency departments. Hypothesis: There will be a higher incidence of ankle sprains among younger populations (≤25 years old) and in female patients. Complications and procedures will differ between ankle sprain types. Lateral ankle sprains will have lower health care charges relative to medial and high ankle sprains. Study Design: Descriptive epidemiological study. Level of Evidence: Level 3. Methods: A cross-sectional study of the 2010 Nationwide Emergency Department Sample was conducted. Outcomes such as charges, complications, and procedures were compared using propensity score matching between lateral and medial as well as lateral and high ankle sprains. Results: The sample contained 225,114 ankle sprains. Female patients sustained more lateral ankle sprains (57%). After propensity score adjustment, lateral sprains incurred greater charges than medial ankle sprains (median [interquartile range],

Among complications, pain in the limb (1.92% vs 0.52%, P = 0.03), sprain of the foot (2.96% vs 0.70%, P < 0.01), and abrasion of the hip/leg (1.57% vs 0.35%, P = 0.03) were more common in lateral than medial ankle sprain events. Among procedures, medial ankle sprains were more likely to include diagnostic radiology (97.91% vs 83.62%, P < 0.01) and less likely to include medications than lateral ankle sprains (0.87% vs 2.79%, P < 0.01). Hospitalizations were more common following high ankle sprains than lateral ankle sprains (24 [6.06%] vs 1 [0.25%], P < 0.01). Conclusion: Ankle sprain emergency department visits account for significant health care charges in the United States. Age- and sex-related differences persist among the types of ankle sprains. Clinical Relevance: The health care charges associated with ankle sprains indicate the need for additional preventive measures. There are age- and sex-related differences in the prevalence of ankle sprains that suggest these demographics may be risk factors for ankle sprains.

PATIENT CHARACTERISTICS, HEALTH OUTCOMES, AND PREDICTORS OF ORGAN FAILURE OR REJECTION OF ORGAN TRANSPLANT RECIPIENTS IN THE UNITED STATES

Abstract This study explores the relationship between adult obesity prevalence and obesity-related state policymaking in the United States. We examine whether 2009 obesity prevalence and the change in prevalence between 2000 and 2009 are associated with obesity-related state laws and regulations introduced or enacted between 2009 and 2011. Policies that exclusively target youth are eliminated from our analysis. Adult obesity prevalence increased in all 50 states over the decade studied, with a slight decrease in Washington, DC. Increases in prevalence are significantly associated with fewer policies in the South and Midwest Census regions and the East North Central and South Atlantic Census divisions. Findings suggest the need for greater advocacy and an opportunity for obesity to rise on state policy agendas.

Emergency Department Visits Associated With Ankle Sprains In The United States

Abstract Aim: To estimate the healthcare utilization and costs in elderly lung cancer patients with and without pre-existing chronic obstructive pulmonary disease (COPD). Methods: Using Surveillance, Epidemiology and End Results (SEER)-Medicare data, this study identified patients with lung cancer between 2006–2010, at least 66 years of age, and continuously enrolled in Medicare Parts A and B in the 12 months prior to cancer diagnosis. The diagnosis of pre-existing COPD in lung cancer patients was identified using ICD-9 codes. Healthcare utilization and costs were categorized as inpatient hospitalizations, skilled nursing facility (SNF) use, physician office visits, ER visits, and outpatient encounters for every stage of lung cancer. The adjusted analysis was performed using a generalized linear model for healthcare costs and a negative binomial model for healthcare utilization. Results: Inpatient admissions in the COPD group increased for each stage of non-small cell lung cancer (NSCLC) compared to the non-COPD group per 100 person-months (Stage I: 14.67 vs 9.49 stays, p < .0001; Stage II: 14.13 vs 10.78 stays, p < .0001; Stage III: 28.31 vs 18.91 stays, p < .0001; Stage IV: 49.5 vs 31.24 stays, p < .0001). A similar trend was observed for outpatient visits, with an increase in utilization among the COPD group (Stage I: 1136.04 vs 796 visits, p < .0001; Stage II: 1325.12 vs 983.26 visits, p < .0001; Stage III: 2025.47 vs 1656.64 visits, p < .0001; Stage IV: 2825.73 vs 2422.26 visits, p < .0001). Total direct costs per person-month in patients with pre-existing COPD were significantly higher than the non-COPD group across all services (
