Depression symptomatology and diagnosis: discordance between patients and physicians in primary care settings
<p>Abstract</p> <p>Background</p> <p>To examine the agreement between depression symptoms using an assessment tool (PHQ-9), and physician documentation of the same symptoms during a clinic visit, and then to examine how the presence of these symptoms affects depression diagnosis in primary care settings.</p> <p>Methods</p> <p>Interviewer administered surveys and medical record reviews. A total of 304 participants were recruited from 2321 participants screened for depression at two large urban primary care community settings.</p> <p>Results</p> <p>Of the 2321 participants screened for depression 304 were positive for depression and of these 75.3% (n = 229) were significantly depressed (PHQ-9 score ≥ 10). Of these, 31.0% were diagnosed by a physician with a depressive disorder. A total of 57.6% (n = 175) of study participants had both significant depression symptoms and functional impairment. Of these 37.7% were diagnosed by physicians as depressed. Cohen's Kappa analysis, used to determine the agreement between depression symptoms elicited using the PHQ-9 and physician documentation of these symptoms showed only slight agreement (0.001–0.101) for all depression symptoms using standard agreement rating scales. Further analysis showed that only suicidal ideation and hypersomnia or insomnia were associated with an increased likelihood of physician depression diagnosis (OR 5.41 P sig < .01 and (OR 2.02 P sig < .05 respectively). Other depression symptoms and chronic medical conditions had no affect on physician depression diagnosis.</p> <p>Conclusion</p> <p>Two-thirds of individuals with depression are undiagnosed in primary care settings. While functional impairment increases the rate of physician diagnosis of depression, the agreement between a structured assessment and physician elicited and or documented symptoms during a clinical encounter is very low. Suicidality, hypersomnia and insomnia are associated with an increase in the rate of depression diagnosis even when physician and self report of the symptom differ. Interventions that emphasize the use of routine structured screening of primary care patients might also improve the rate of diagnosis of depression in these settings. Further studies are needed to explore depression symptom assessment during physician patient encounter in primary care settings.</p

Enzyme estimates of infarct size correlate with functional and clinical outcomes in the setting of ST-segment elevation myocardial infarction
Background: Cardiac biomarkers are routinely obtained in the setting of suspected myocardial
ischemia and infarction. Evidence suggests these markers may correlate with functional and clinical
outcomes, but the strength of this correlation is unclear. The relationship between enzyme
measures of myocardial necrosis and left ventricular performance and adverse clinical outcomes
were explored.
Methods: Creatine kinase (CK) and CK-MB data were analyzed, as were left ventricular ejection
fraction (LVEF) by angiogram, and infarct size by single-photon emission computed tomography
(SPECT) imaging in patients in 2 trials: Prompt Reperfusion In Myocardial-infarction Evolution
(PRIME), and Efegatran and Streptokinase to Canalize Arteries Like Accelerated Tissue
plasminogen activator (ESCALAT). Both trials evaluated efegatran combined with thrombolysis for
treating acute ST-segment elevation myocardial infarction (STEMI).
Results: Peak CK and CK area-under-the-curve (AUC) correlated significantly with SPECTdetermined
infarct size 5 to 10 days after enrollment. Peak CK had a statistically significant
correlation with LVEF, but CK-AUC and LVEF correlation were less robust. Statistically significant
correlations exist between SPECT-determined infarct size and peak CK-MB and CK-MB AUC.
However, there was no correlation with LVEF for peak CK-MB and CK-MB AUC. The combined
outcome of congestive heart failure and death were significantly associated with CK AUC, CK-MB
AUC, peak CK, and peak CK-MB measurements.
Conclusion: Peak CK and CK-MB values and AUC calculations have significant correlation with
functional outcomes (LVEF- and SPECT-determined infarct size) and death or CHF outcomes in
the setting of STEMI. Cardiac biomarkers provide prognostic information and may serve as valid
endpoint measurements for phase II clinical trials
