data mining in healthcare articles
December 5, 2020
This leads to us wondering why are the authors limiting the scope of TBI research to only these two levels, and why not (as shown in Middleware is software that works to connect two programs that are otherwise not connected. [http://mbe.oxfordjournals.org/content/24/8/1596.abstract] 10.1093/molbev/msm092, Liu W, Li R, Sun JZ, Wang J, Tsai J, Wen W, Kohlmann A, Williams PM: PQN and DQN: Algorithms for expression microarrays.  who created a Bioinformatics suite of software tools they call khmer. , in their 2012 editorial, discuss JAMIA’s focus of Big Data in TBI. In this model, each point (or instance) is a tweet, and the features each represent dictionary terms which occur more than 10 times per week. As simple Linear ARX could not handle the fact that the number of Twitter users is only bounded below by 0 (rather than being completely bounded between 0% and 100%), and so the authors introduce a logit link function for the CDC data and use a logarithmic transformation of the Twitter data. It could also be beneficial if numerous sensors were checked to find the best set of sensors for each ailment prediction. Also work should be done to determine whether research done in one area of the world can be translated to another (e.g. Tweets containing the following attributes were not used for analysis: if located outside the United States, from a user with a time zone outside the US, containing less than five words, not in English, not containing ASCII characters, and those submitted through the “API”. These variables were used to make the final prediction model using multivariate logistic regression, which will be used to develop their Minimizing ICU Readmission (MIR) score. This result shows that good prediction performance can be reached by using a small set of physiological variables. Advancements in Big Data processing tools, data mining and data organization are causing market research firms to predict huge gains in the predictive analytics market for healthcare.. The authors tested extraction accuracies for each of the 5 expression of interest categories in terms of precision and accuracy: personal experience (0.87 and 0.82), advise (0.91 and 0.62), Information (0.93 and 0.91), support (0.89 and 0.90), and outcome (0.80 and 0.58). [ Through MIR, Ouanes et al. TBI looks to use the health information from the discussed levels, combine the aggregated information in order to provide the most health gains, and help in offering the best of modern health practices. The feature selection method chosen was univariate analysis selecting variables with (P < 0.2) to add to the final model, and used the Akaike Information Criterion (AIC) During the 1990s and early 2000's, data mining was a topic of great interest to healthcare researchers, as data mining showed some promise in the use of its predictive techniques to help model the healthcare system and improve the delivery of healthcare â¦ Research was performed on 3462 patients (out of 5014) admitted to an ICU for a minimum of 24 hours, gathered from 4 different ICUs from the Outcomerea database. The studies discussed in this subsection have a similar research goal to the previous subsection of attempting to detect and track ILI epidemics, but instead of using search query data the researchers use Twitter post data. Data gathered from the population through social media could possibly have low Veracity leading to low Value, but techniques for extracting the useful information from social media (such as Twitter posts), this line of data can also have Big Value. They also determined that the bilateral temporal lobes are closely related to aging and arterial stiffness, while the occipital lobes correspond to clinical markers for anemia.  that just in the United States, using data mining in Health Informatics can save the healthcare industry up to $450 billion each year. All the studies covered in this section will cover data at the tissue level and venture to answer human-scale biology questions including: creating a full connectivity map of the brain, and predicting clinical outcomes by using MRI data. For the modified VFDT, one or more pointer(s) were added to each of the terminating leaf nodes, where each base node corresponds to a distinct medical condition and each pointer corresponds to one medical records of a previous patient. As a note, the CDC splits the US into 9 regions and this study looked to make predictions also using these regions of separation. With this, data used by Clinical Informatics research has Big Value. . As sensors are not perfect (creating missing or erroneous data during a given time period), especially when being used for real-time analysis, future work will need to focus on developing and testing methods that can handle such data in the most reliable and efficient way. Research on using these tools and techniques for Health Informatics is critical, because this domain requires a great deal of testing and confirmation before new techniques can be applied for making real world decisions across all levels. With ColoPrint, a patient can be classified as either low or high risk. . The system starts by creating and assigning the states to the synthesized patients and for DM II they decided upon 6 states (also described in medical research Google Scholar. Pattern Recognit 1997,30(7):1145–1159. doi:10.1371/journal.pone.0019467 doi:10.1371/journal.pone.0019467 10.1371/journal.pone.0019467, McDonald E, Brown CT: khmer: Working with big data in Bioinformatics. Also there was one prediction model applied, where as with more tested they could have found that a different model generated better results with less error across the US and within the tested region. Data mining applications can greatly benefit all parties involved in the healthcare industry.

Similar to the United State’s CDC the MOH also releases their data with a 1 to 2 week delay. This section will sample two different categories of data steam studies: making prognosis and diagnosis predictions for patients, and detecting if a new born is experiencing a cardiorespiratory spell both in a real time. The Benefits of Data Mining in Healthcare: The Future Has Arrived. The CFS method finds variables that are both strongly correlated to the final prediction and that are weakly correlated between them. [http://dx.doi.org/10.1155/2012/580186]. These studies are only a taste of the future possibilities that could be achieved through data mining and analysis of Big Data for Health Informatics. Data stream mining presented here has shown the potential to be beneficial for clinical practice as it can be extended to be used in real time by use of efficient algorithms and methods (that are not previously used in the clinic). The HLgof is used to determine if logistic regression models have sufficient calibration (discussed by Hosmer et al. The four subfields discussed in this study correspond to the data levels, but the question level in a given work may be different from its data level. This line of research can help health officials, physicians, hospitals in reacting to epidemics faster and work to stop them better (faster) than with traditional methods used today such as the CDC or MOH reports.

The HCP could benefit from employing a comparison to histological image data. Data mining holds great potential in the healthcare sector. Again more variation of data could be added to this research as all the data was gathered from one source. & Wald, R. A review of data mining using big data in health informatics. The way forward for Health Informatics is definitely exploiting the Big Data created throughout all the various levels of medical data and finding ways to best analyze, mine and answer as many medical questions as possible. From the results for this one tested patient, they showed that their sliding baseline method could achieve clinically significant results for heart rate detection, with a specificity of 98.9% and a sensitivity of 100%. 3.4 Data mining: The fourth stage includes data mining where suitable Data Mining technique is applied on the transformed data in order to extract valuable information. But, the potential of data mining is much bigger â it can provide question-based answers, anomaly-based discoveries, provide more informed decisions, probability â¦ Vilamoura, Portugal: Nature Publishing Group, based in London, UK; 2012:61–70. Campbell et al. Its a utilized procedure for expectation. Big Volume comes from large amounts of records stored for patients: for example, in some datasets each instance is quite large (e.g. The basic goal of Health Informatics is to take in real world medical data from all levels of human existence to help advance our understanding of medicine and medical practice. fitting the regression model with the keyword index to that of the influenza case data.  developed an automated method that can analyze a Big Volume of search queries from Google with the goal of tracking ILI within a given population. Through this combination, questions throughout all levels can be more precisely answered and results can be validated both more quickly and more accurately. It is noted in Classifiers that are employed for this line of research should be able to make decisions as a physician would do, that is, be able to look at a patient’s medical attributes and make subjective decisions. This subset was then populated by one variable (gender) giving the final EI subset of 24 variables. The results of these research efforts lead to the idea that microarray data could give similar results if these procedures were applied to other types of cancers in order to help physicians both diagnose and begin to treat their patients. This research is especially important for patients with increasing age as the older a patient is the less likely a harsh treatment would be beneficial. As previously mentioned above, the challenge with social media data is that although it is clearly High Volume, Velocity, and Variety, it could have both low Veracity and Value (data coming in could be unreliable, as discussed by Hay et al. [http://jco.ascopubs.org/content/28/15/2529.abstract] 10.1200/JCO.2009.23.4732, Salazar R, Roepman P, Capella G, Moreno V, Simon I, Dreezen C, Lopez-Doriga A, Santos C, Marijnen C, Westerga J, Bruin S, Kerr D, Kuppen P, van de Velde C, Morreau H, Van Velthuysen L, Glas AM, Van’t Veer LJ, Tollenaar R: Gene expression signature to improve prognosis prediction of stage II and III colorectal cancer. http://dx.doi.org/10.1007/978–3-540–85836–2_29], Thiagarajan R, Manjunath G, Stumptne M: Computing semantic similarity using Ontologies. It should be noted that each patient could potentially fall into more than one of these categories, but this is not an issue due to there being three separate binary models built. A system such as this one is difficult to test outside letting real patients test this system in numerous field tests. These medical records, through Natural Language Processing (sentence and semantic similarity The only worry would be that with the rule-based side of the models there could possibly be too much rigidity causing the absence of physician discernment in the final model. This is to say that by creating sparse, linear combinations of explanatory variables, the developed approach concurrently performs feature selection and dimensionality reduction (that is, creating new, more condensed features). Additionally, it would be interesting to see if the formula created on this study could work as well for ILI epidemics that happen many years in the future from the time period used to train the model or in a different population that uses the same language. information from the data. Butte et al. The lines between each subfield of Health Informatics can be blurred in terms of definition, confusing which subfield a study should fall under; therefore, this paper will be deciding subfield membership by the highest level of data used for research and will be the organizing factor for Sections “1” through 1. In Estella et al. if a machine detects heart rate under or over a cutoff, then notify physicians). California Privacy Statement, The first study uses both MRI data and a list of clinical features with the goal to find correlations between physical ailments to that of different locations of the brain. [Accessed: 2013-9-18], Centers for Disease Control and Prevention: Diabetes report card 2012. This survey discussed a number of recent studies being done within the most popular sub branches of Health Informatics, using Big Data from all accessible levels of human existence to answer questions throughout all levels. The data experts have a belief that almost 30% of the overall expenditure cost of healthcare can be reduced by using data mining. Annese Rolia J, Yao W, Basu S, Lee WN, Singhal S, Kumar A, Sabella S: Tell me what i don’t know - making the most of social health forums. The second line of study is testing if using search query data or Twitter post data can effectively track an epidemic across a given population (in real-time). method is not tested on real world data and would need to be before its usefulness can be determined and can be legitimately compared to IBM’s method. is the weight for the i th keyword and HPC Source 2013, 33–35. Campbell AJ, Cook JA, Adey G, Cuthbertson BH: Predicting death and readmission after intensive care discharge. The medical industry is all about efficiency, and proper analysis of big data sets can help doctors and nurses improve patient care.  was used to create their predictive model and was evaluated with tenfold cross-validation. Considering this data is only recently released, the research applying this data is all in the future, but with the technology being so advanced there is endless possibility for studies employing this data for heath information gain. They built and trained their model based on data from the years 2003-2007 and the validation was done on data from 2008. Another issue for future work in this line research is the need to devise and test numerous classification methods to find the best for both prognosis and acute problem detection (knowing that the best choices could be different for different ailments). RFE and ADT is a good combination as RFE brings accuracy and diversity to the model, and ADT allows for more information to be gained about an instance as it goes along the tree.
