BACKGROUND |
Increased anxiety correlates with increased complications after acute myocardial infarction. Anxiety levels and use of anxiolytic agents have not been compared between smokers and nonsmokers hospitalized because of acute myocardial infarction. |
OBJECTIVES |
To compare anxiety level, sociodemographic factors, and clinical variables between smokers and nonsmokers hospitalized with acute myocardial infarction and to examine predictors of use of beta-blockers and anxiolytic agents among smokers and nonsmokers. |
METHODS |
Secondary data analysis of a prospective multisite study on anxiety in 181 smokers and 351 nonsmokers with acute myocardial infarction. Anxiety was measured by using the State Trait Anxiety Inventory and the anxiety subscale of the Basic Symptom Inventory within 72 hours of admission. |
RESULTS |
Smokers reported higher anxiety levels than nonsmokers reported on both anxiety scales. Female smokers reported the highest anxiety and peak pain levels of all, yet women were the least likely to receive anxiolytic agents. Smoking status was not a predictor for anxiety level when sex, peak pain, use of beta-blockers in... |
CONCLUSIONS |
Older female smokers are at risk for complications because they are older than their male counterparts and less likely to receive beta-blockers and antianxiety medications in the emergency department.Carbon-Doped Boron Nitride Nanomesh: Stability and Electronic Properties of Adsorbed Hydrogen and Oxygen |

OBJECTIVES |
To determine the agreement between patient-reported symptoms of chest pain, dyspnea, and cough and the documentation of these symptoms by physicians in the electronic medical record. |
METHODS |
Symptoms reported on patient-provided information forms between January 1, 2006, and June 30, 2006, were compared with those identified by natural language processing of the text of clinical notes from care providers. Terms that represent the 3 symptoms were used to search clinical notes electronically with subsequent ... |
RESULTS |
Symptoms reported by 1119 patients age 18 years or older were compared with the nonnegated terms identified in their clinical notes. Positive agreement was 74, 70, and 63 for chest pain, dyspnea, and cough, while negative agreement was 78, 76, and 75, respectively. Kappa statistics were 0.52 (95% confidence interval [C... |
CONCLUSIONS |
We found discordance between patient self-report and documentation of symptoms in the medical record. This discordance has important implications for research studies that rely on symptom information for patient identification and may have clinical implications that must be evaluated for potential impact on quality of ... |
