Trends in Health Information Systems and Applications Essay

Trends in Health Information Systems and Applications - Essay Example Overview – today's medical professionals work in an increasingly hurried environment; it is important to them they can access the right information at the right time when it is needed. The main problems identified in a medical practice which bother a lot are delays in obtaining patient information, misplaced laboratory test results, delays in updating of medical records and a host of other valid concerns such as incorrect vital physical details of a patient. Problem - the problem is really a question of properly managing the flow of information from those who obtained those records to giving the same information to those who need it the most – the medical practitioners. Present information systems used by hospitals, clinics and other medical institutions are often overwhelmed by a deluge of data. If not properly managed through the right information technologies, there is always the danger of mistakes being committed with a possibility of being sued for medical malpract ice. The identified need is to use technology that can provide the information in a proximate manner in terms of both time and space.

Calculation of Values Essay Example | Topics and Well Written Essays - 1250 words

Calculation of Values - Essay Example The following data are considered not valid for analysis: results that were reported erroneously (reporting errors) such as data with inappropriate units and "results reported as approximately 10, 100 or 1000 times greater or smaller than the majority of submitted results" (Croucher, 2004); results reported as not detected (n.d.); and results from participants not quoting a percentage recovery. Aside from these non-valid data, each report has the following points to be considered for removal of non-valid data. Results for total fat recorded without any reference to the use of an acid hydrolysis step; and nitrogen results that appeared to be for protein i.e. results approximately a factor of 6 greater than the majority of results (Knaggs, 2004a). Results reported as 0 ug/kg; results from participants not quoting a percentage recovery or stating na, EXCEPT for total AF, where participants submitted results that were the sum of their recovery corrected individual aflatoxins (Walker, 2005). Participants reporting not detected and subsequently assigned a result of 0g/kg; results from participants whose recovery is outside the range 70-110%; and results below the stated LOQ including results with no LOQ stated (Leach, 2005). The value of p estimates the limits ... t of 0g/kg; results from participants whose recovery is outside the range 70-110%; and results below the stated LOQ including results with no LOQ stated (Leach, 2005). ii) Minimizing the influence of outliers by the use of a robust statistical procedure to derive the mean iii) Normality (Kolmogorov - Smirnov test), or otherwise, of the distribution of the results is considered. iv) Assessment of the standard uncertainty () of the robust mean = /n, = the standard deviation of the robust mean n = the number of data points used to calculate the robust mean B. Target Standard Deviation for the Round The value of p estimates the limits of a satisfactory performance in a FAPAS proficiency test (FAPAS, 2002). In cases where the value of p does not reflect best practice for the analyses in question, the predictive models of the appropriate form of the Horwitz equation are valuable indicators of the best practice. This equation predicts a standard deviation from a given concentration (c) and requires c to be expressed as a dimensionless mass ratio (1ppm = 10-6 or % = 10-2) i) For analyte concentrations= (0.22c) / mr ii) For analyte concentrations 120 ppb and 13.8% = (0.2c0.8495) / mr iii) For analyte concentrations > 13.8 % = (0.01c0.5) / mr where, c = concentration (assigned value), expressed as a dimensionless mass ratio mr = dimensionless mass ratio. In all reports, the was calculated according to the equations above. In report 0141 however only the value of for the ash was estimated in this manner. The value of for moisture, total fat, nitrogen and hydroxyproline was derived from collaborative trial data assuming a linear relationship : = (RSDR / 100)c where, RSDR = Relative
