Cost-effectiveness of cardiac troponin I in a systematic chest pain evaluation protocol: use of cardiac troponin I lowers length of stay for low-risk cardiac patients.
We evaluated several measures of clinical and fiscal interest to assess the effect of adding an automated cardiac troponin I (c-TnI) assay to our current cardiac panel, which consists of creatine kinase MB (CK-MB), myoglobin, total CK activity, and a calculated CK-MB relative index. Samples were collected on admission and at 3, 6, and 8 hours after admission as part of our diagnostic protocol. ⋯ We found that adding c-TnI to our testing regimen decreased LOS for the large test population. Within this large test population, patients classified as low risk for acute myocardial infarction experienced statistically and clinically significant shorter LOS and lower total and variable hospital costs; for patients with unstable angina, there was an increase (though not statistically significant) in laboratory costs.

Outcomes research is the fifth discipline of the fifth generation of managed care: utility of a single troponin-T.
The fifth generation of managed care is disease management. Diseases have measurable risk in providing laboratory and medical services. The link between managing services and managing risk can be aided by leveraging the laboratory. We wish to remodel laboratory services to fit the needs of the use, thereby using the laboratory for competitive advantage by redesigning a desired output using a formal structured process. Outcomes research is the systems framework for the remodeling process through the link of laboratory output to clinical and financial outcomes. A process redesign model connects the use of laboratory tests to improved medical services by leveraging resources to achieve measurable improvement over current results. This view of outcomes research seeks both competitive advantage and measurable improvements in quality. ⋯ The study supports our hypothesis that the laboratory can systematically redesign its technology strategy and participate in the construction of a clinical pathway for the discharge from ED or admitting decisions with a test 98% sensitive for identifying patients with serious coronary ischemia by 3.5 hours after the onset of symptoms.

Nonacetylated salicylates are frequently used in the treatment of musculoskeletal complaints and pain management in older patients because of their possible lower gastrointestinal and renal toxicity as compared with other nonsteroidal anti-inflammatory agents. We report five patients with chronic salicylate intoxication seen at the Atlanta VA Medical Center. All charts of patients diagnosed with salicylate toxicity were reviewed, and cases with acute, intentional intoxication were excluded. ⋯ A significantly decreased urate level and a wide anion gap were consistent findings as well. Two of the patients improved after hydration and discontinuation of use of the drug, two required alkalinization of the urine, and one required dialysis. Clinicians need to be more aware of the potential toxicity, including life-threatening complications, with the use of salicylates, particularly in high risk populations such as elderly patients and patients with multiple medical problems.

The tricyclic antidepressant imipramine has shown analgesic effect in human clinical and experimental pain studies. The aim of the present study was to test the effect of imipramine on a pure short-term nociceptive stimulus with pin-prick pain quality. In a randomized, placebo-controlled, double-blind, crossover study, the hypoalgesic effect of a single oral dose of 100 mg imipramine was investigated in 10 healthy volunteers. ⋯ This study demonstrates the important fact that a drug may show clear analgesic effect in some experimental pain models while it is without effect in other models; e.g. imipramine is known to affect pain tolerance and summation thresholds. Pre-clinical tests of potentially analgesic drugs should therefore be based on different pain-stimulation modalities.

The aims of this study were: (1) to compare two groups of patients with chronic pain conditions (work-related muscular pain, mainly low back pain, and fibromyalgia) in general coping and pain-specific coping; (2) to examine the relationship between general and pain-specific coping and, (3) to examine the influence of state-trait anxiety on general and pain-specific coping. The sample included 80 individuals (range=19-70 years; mean=47; SD=9.9), who were patients at two pain management clinics for examination of their physical and psychosocial health conditions and consideration on disability pension. The patients were asked to respond to theStrategies to Handle Stress Questionnaire, theCoping Strategies Questionnaireand theState-Trait Anxiety Inventory. ⋯ Anxiety-prone patients with fibromyalgia might benefit from psychological support in the process of coping with pain.
