Quality and cost improvement of healthcare via complementary measurement and diagnosis of patient general health outcome using electronic health record data: research rationale and design.

In this evolving 'third era of health', one of the US Health Care Reform Act's goals is to effectively facilitate the primary care physician's ability to better diagnose and manage the health outcome of the outpatient. That goal must include research on the complementary quantitative-qualitative assessment and rating of the patient's health status. This paper proposes an overview of the rationale and design of a research program for a balanced measurement and diagnostic clinical decision support system (CDSS) of the changing general health status of the patient -including disease- using electronic health record (EHR) data. The rationale, objectives, health metric-diagnostic tools architecture, simulation-optimization, and clinical trials are outlined. Resources, time frames, costs, feasibility, healthcare benefits and data-integration of the project are delineated. The basis and components of the research program to achieve an automated-CDSS to complement physician's clinical judgment, calculating a mathematical 'health equation' from each patient's EHR database, assisting physician-patient collaboration to diagnose, and improve general health outcomes is described. Use of multiple dimensional index, ways of classification, and causal factors' assessments, to arrive at the EHR-based CDSS algorithm-software providing a general health level and state rating of the patient are proposed. Its application could provide a compass for the general practitioner's best choice and use of the myriad of healthcare educational and technological options available with lower costs for everyday clinical practice and research. It could advance the approaches and focus of the 'eras of diseases', to the promising 'era of health', in an integrated, general approach to 'health.'

The evidence for a narrower thyrotropin reference range is compelling.

Debate and controversy currently surround the recommendations of a recent consensus conference that considered issues related to the management of early, mild, or so-called subclinical hypothyroidism and hyperthyroidism. Intimately related to the controversy is the definition of the normal reference range for TSH. It has become clear that previously accepted reference ranges are no longer valid as a result of both the development of more highly sensitive TSH assays and the appreciation that reference populations previously considered normal were contaminated with individuals with various degrees of thyroid dysfunction that served to increase mean TSH levels for the group. Recent laboratory guidelines from the National Academy of Clinical Biochemistry indicate that more than 95% of normal individuals have TSH levels below 2.5 mU/liter. The remainder with higher values are outliers, most of whom are likely to have underlying Hashimoto thyroiditis or other causes of elevated TSH. Importantly, data indicating that African-Americans with very low incidence of Hashimoto thyroiditis have a mean TSH level of 1.18 mU/liter strongly suggest that this value is the true normal mean for a normal population. Recognition and establishment of a more precise and true normal range for TSH have important implications for both screening and treatment of thyroid disease in general and subclinical thyroid disease in particular.

Optimal thyrotropin level: normal ranges and reference intervals are not equivalent.

This paper marshals arguments in support of a narrower, optimal or true normal range for thyrotropin (TSH) of 0.4 to 2.5 mIU/L, based on clinical results and recent information on the relatively stable and narrow range of values in patients without thyroid disease. The terminology used for TSH results is clarified in an attempt to help physicians interpret, explain, and respond to TSH test results for their patients.

Discovery of unsuspected thyroid pathologic conditions after trauma to the anterior neck area attributable to a motor vehicle accident: relationship to use of the shoulder harness.

OBJECTIVE: To alert physicians to the possibility of antecedent trauma to the neck in patients presenting with a thyroid nodule or with symptoms and signs related to the thyroid gland. METHODS: We present five case reports in which the cause of thyroid nodular disease was suspected to have been trauma to the anterior neck area during an earlier motor vehicle accident in which the shoulder harness impacted the neck. RESULTS: In five female patients, shoulder harness trauma from an automobile accident led to the subsequent discovery of a thyroid lesion. Four of the five patients underwent surgical removal of the thyroid nodule. Although traumatic injury of the thyroid may be common, we found only one report in the medical literature regarding the discovery of a thyroid nodule or thyroiditis in the setting of traffic accident-related trauma to the thyroid gland. CONCLUSION: In the initial assessment of patients with thyroid nodular disease, we emphasize the importance of obtaining a detailed and comprehensive history, including inquiry about trauma to the neck. Prompt diagnostic accuracy will help avoid unnecessary costs and risks in the workup of such patients.
