Association Between Radiologic Incidental Findings and Resource Utilization in Patients Admitted With Chest Pain in an Urban Medical Center.

BACKGROUND: Increasing use of testing among hospitalized patients has resulted in an increase in radiologic incidental findings (IFs), which challenge the provision of high-value care in the hospital setting. OBJECTIVE: To understand impact of radiologic incidental findings on resource utilization in patients hospitalized with chest pain. DESIGN: Retrospective observational cross sectional study. SETTING: Academic medical center. PARTICIPANTS: Adult patients hospitalized with principal diagnosis of chest pain. MEASUREMENTS: Demographic, imaging, and length of stay (LOS) data were abstracted from the medical charts. We used multiple logistic regression to evaluate factors associated with radiologic IFs and negative binomial regression to evaluate the association between radiologic IFs and LOS. RESULTS: 1811 consecutive admissions with chest pain were analyzed retrospectively over a period of 24 months; 376 patients were included in the study after exclusion criteria were applied and readmissions removed. Of these, 197 patients (52%) had 364 new radiologic IFs on imaging; most IFs were of minor (50%) or moderate clinical significance (42%), with only 7% of major significance. Odds of finding radiologic IFs increased with age (adjusted odds ratio, 1.04; 95% confidence interval [CI], 1.01-1.06) and was associated with a 26% increase in LOS (adjusted incidence rate ratio, 1.26; 95% CI, 1.07-1.49). CONCLUSION: Radiologic IFs were very common among patients hospitalized with chest pain of suspected cardiac origin and independently associated with an increase in the LOS. Interventions to address radiologic IFs may reduce LOS and, thereby, support high-value care. Journal of Hospital Medicine 2017;12:323-328.

Management of Cocaine-Induced Myocardial Infarction: 4-Year Experience at an Urban Medical Center.

OBJECTIVES: In 2008, the American Heart Association and the American College of Cardiology released guidelines for the management of cocaine-induced myocardial infarction (CIMI). We hypothesized that CIMI patients are likely to receive less invasive and more conservative management than patients with MI without history of cocaine use. METHODS: We conducted a retrospective analysis on patients younger than 65 years presenting with acute MI between April 1, 2008 and December 31, 2012. Patients were classified as cocaine-negative MI or CIMI based on either urine toxicology results or self-reported cocaine use. Categorical and continuous variables were compared using χ(2) or t test as appropriate. The primary outcome was cardiac catheterization or stress testing. The secondary outcome was a 30-day readmission rate for major adverse cardiovascular events. Multiple logistic regression models calculated odds ratios (ORs) for the primary outcomes adjusting for patient demographics and comorbidities. RESULTS: Of 378 MI patients, 4.2 % had CIMI. CIMI patients were younger (50 vs 54 years; P < 0.01) predominantly African American (56% vs 16%, P < 0.01), and mostly active smokers (88% vs 58%, P = 0.02). They were more likely to receive stress testing (adjusted OR 3.61, 95% confidence interval 1.04-12.53) and less likely to undergo cardiac catheterization (adjusted OR 0.12, 95% confidence interval 0.03-0.45). The 30-day readmission rate for major adverse cardiovascular events was higher in CIMI compared with cocaine-negative MI patients (38% vs 13%; P = 0.03). CONCLUSIONS: The use of cocaine in patients presenting with acute MI appears to impact management decisions of providers. Patient-centered postdischarge arrangements need better coordination for this patient group to optimize their follow-up care.
