References to “one embodiment,” “at least one embodiment,” “an embodiment,” “one example”, “an example”, “for example” and so on, indicate that the embodiment(s) or example(s) so described may include a particular feature, structure, characteristic, property, element, or limitation, but that not every embodiment or example necessarily includes that particular feature, structure, characteristic, property, element, or limitation. Furthermore, repeated use of the phrase “in an embodiment” does not necessarily refer to the same embodiment.
A “patient dataset” corresponds to historical data pertaining to one or more human subjects previously examined by a medical practitioner. In an embodiment, the patient dataset includes information pertaining to measured one or more physiological parameters. In an embodiment, the patient dataset is utilizable as a training dataset to train a classifier.
“Patients” refer to one or more human subjects that may receive medical treatment for an ailment/health condition.

Based on the measured one or more physiological parameters, a health condition of the patients is determined.
“One or more categories” correspond to a range of a health condition score. In an embodiment, the patients are categorized in the one or more categories based on the measured one or more physiological parameters. In an embodiment, a category in which a patient has been categorized is indicative of a range of the health condition score that may be associated with the patient. For example, if the one or more categories include two categories, i.e., category-1 and category-2. The health conditions score range for the category-1 is 0-25 and that for category-2 is 26-42. If a patient is categorized in category-2, the health condition score of the patient lies in the range of 26-42.
A “stroke score” refers to a score assigned to a human subject based on the measured one or more physiological parameters. In an embodiment, the stroke score is indicative of a severity of the stroke. In an embodiment, the stroke score is in accordance to a National Institute of Health Stroke Scale (NIHSS) score.

At step 102, a distribution of one or more physiological parameters associated with the one or more patients is determined. Prior to determining the distribution, a patient dataset is extracted from a database server. In an embodiment, the patient dataset includes at least a medical record data associated with each of the one or more patients. In an embodiment, the medical record data includes information pertaining to at least a measure of the one or more physiological parameters associated with a patient. In an embodiment, the one or more physiological parameters may include, but are not limited to, an age, a number of days between an onset of a medical condition and a first medical consultation, a hemoglobin count, an RBC count, a creatinine count, a serum sodium count, a blood albumin count, a blood platelet count, or a complete blood count.
A person having ordinary skill in the art would understand that the scope of the disclosure should not be limited to the above disclosed one or more physiological parameters. In an embodiment, the one or more physiological parameters may further include other types of physiological parameters. Further, the person having ordinary skill in the art would understand that the types of the one or more physiological parameters may vary based on the medical condition. For example, the one or more physiological parameters required for diagnosing a first health condition (e.g., a cardio-vascular disease) may be different from the one or more physiological parameters required for diagnosing a second health condition (e.g., osteoporosis).
Post extracting the patient dataset, the distribution of each of the one or more physiological parameters is determined on the entire patient dataset. In an embodiment, one or more curve fitting techniques are used to determine the distribution of the one or more physiological parameters. In an embodiment, the curve fitting techniques may involve determining a mathematical equation that can best fit the data points (or measure of the one or more physiological parameters across the patient dataset). For example, the age distribution of the patient dataset usually follows a Gaussian distribution curve. Similarly, the creatinine count distribution can be best described by an exponential distribution. Example distribution of the one or more physiological parameters is described in
In an embodiment, the patient dataset includes a measure of a health condition score for each of the one or more patients. In an embodiment, the health condition score is determined by the medical practitioner during the physical examination of the one or more patients. In an embodiment, determining the distribution of the one or more physiological parameters involves determining the distribution of the health condition score across the patient dataset. In an embodiment, the health condition score corresponds to a measure of a severity associated with a health condition or a disease. For example, a National Institute of Health Stroke Scale (NIHSS) is a measure of a stroke score.
A person having ordinary skill in the art would understand that the medical record data includes the measure of the health condition score. This health condition score may be used for training the classifier.
At step 104, a copula distribution is determined from a family of copula distributions. In an embodiment, the copula distribution is deterministic of a joint distribution of the one or more physiological parameters and the health condition score. In an embodiment, the one or more physiological parameters correspond to a d-dimensional variable with the various physiological parameters as the dimensions. In an embodiment, following equation is representative of the copula distribution:
F(x1,x2, . . . ,xd)=C(F1(x1), . . . ,Fd(xd)) (1)
where,
Fd(xd) corresponds to a univariate distribution of a physiological parameter; and
F corresponds to a multivariate distribution of the d-dimensional variable (i.e., the one or more physiological parameters).
In an embodiment, the determined copula distribution best defines the joint distribution of the one or more physiological parameters and the health condition score. To determine the copula distribution, the patient dataset is ranked based on a measure of a physiological parameter from the one or more physiological parameters. For instance, following is an example patient dataset:
Referring to Table 1 and Table 2, the one or more patients are ranked based on the NIHSS score. For instance, patient-1 is ranked 1st as the NIHSS score of the patient-1 is “2”. Similarly, the patient-6 is ranked 7th as the NIHSS score of the patient-6 is the highest among the other patients listed in the Table 1 (i.e., 19). Further, each physiological parameter from the one or more physiological parameters is ranked across the patient dataset as illustrated in Table 2.
In an embodiment, the copula distribution of the patient dataset and the copula distribution of the ranked patient dataset remain the same. In an embodiment, the copula distribution of the ranked patient dataset is referred as an empirical copula. Following equation represents the empirical copula:
where,
Ũ
f
l
=R
d
i
/n (3)
Rdi: Rank of the observation; and
n: Number of observations or the number of patients in the patient dataset;
Post defining the empirical copula, one or more parameters associated with the empirical copula are estimated. In an embodiment, the one or more parameters associated with the empirical copula include, but are not limited to, a correlation parameter. In an embodiment, Kendall's Tau based estimator or the Spearman's Rho estimator is used for estimating the one or more parameters of the empirical copula. A person having ordinary skill in the art would understand that the scope of the disclosure should not be limited to estimating the one or more parameters using the Kendall's Tau based estimator or the Spearman's Rho estimator. In an embodiment, various other known methods can be used for estimating the one or more parameters of the empirical copula.
As the copula distribution for the ranked patient dataset (i.e., empirical copula) and the original patient dataset is the same, the one or more parameters estimated for the empirical copula will be representative of the one or more parameters of the copula distribution for the original patient dataset. In an embodiment, the one or more estimated parameters are indicative of the copula distribution defining the joint distribution of the one or more physiological parameters and the health condition score. Some examples of the known copula distributions may include, but are not limited to, a Gaussian copula, a Gumbel copula, etc. Following equation represents a Gaussian copula distribution:
C
R
N(u1, . . . ,ud)=ØR(Ø−1(u1), . . . ,Ø−1(ud)) (4)
where,
Ø−1 refers to an inverse cumulative distribution function;
ud refers to a cumulative distribution of the a physiological parameter from the one or more physiological parameters; and
ØR refers to a joint cumulative distribution function.
At step 106, a Bayesian classifier is trained based on the determined copula distribution. In an embodiment, the Bayesian classifier classifies the one or more patients in one or more classes or categories based on the determined copula. As the copula is representative of the joint distribution or the multivariate distribution between the one or more physiological parameters and the health condition score, the copula is indicative of the relationship between the one or more physiological parameters and the health condition score.
In an embodiment, the one or more classes are determined by segregating the health condition score range. Such classes correspond to the one or more categories in which the one or more patients are categorized. In an embodiment, an input, pertaining to the number of classes or segregation of the health condition score range, is received from an administrator/medical practitioner. In an embodiment, a probability that a patient with a set of physiological parameters corresponds to a class from the one or more classes may be determined using the following equation:
P(ci|x)=f(x|ci)P(ci) (5)
where,
f(x|ci): Joint conditional probability function (determined from the copula); and
P(ci): Prior class probability of the class ci.
In an embodiment, the prior class probability of a class corresponds to a probability determined based on number of patients in a particular class. For example, if there are three classes and 30 patients have been classified in class-1, 25 patients have been classified in class-2 and 45 patients have been classified in class-3. In such a scenario, the prior probabilities of class-1, class-2, and class-3 are 0.3, 0.25, and 0.45, respectively.
Post training the Bayesian classifier, the Bayesian classifier is used for classifying a human subject in a category from the one or more categories. For example, the human subject arrives at the hospital with one or more symptoms that may be indicative of a medical condition. A medical practitioner may measure the one or more physiological parameters associated with the human subject. The measure of the one or more physiological parameters is fed to the Bayesian classifier and accordingly the Bayesian classifier categorizes the human subject in a category from the one or more categories. Based on the category in which the human subject has been categorized, the medical practitioner may suggest further course of action. The various courses of action have been described later in conjunction with
A person having ordinary skill in the art would understand that the scope of the disclosure is not limited to training the Bayesian classifier using a copula distribution. In an embodiment, various other classifiers such as a decision tree classifier, support vector machine, and Logistic regression may be used for classifying the human subject in the one or more categories. In an embodiment, such classifiers are first trained on the patient dataset prior to classifying the human subject.
A patient dataset 202 is extracted from the database server. The patient dataset 202 includes information pertaining to the one or more patients and respective measures of the one or more physiological parameters. For example, the patient dataset 202 may include a measure of the NIHSS score (depicted by 204), a hemoglobin measure (depicted by 206), a measure of creatinine (depicted by 208), and age of each of the one or more patients (depicted by 210). The distribution of each of the one or more physiological parameters is determined throughout the patient dataset 202 (as described in the step 102). For instance, the age parameter follows a Gaussian distribution (depicted by 218). Similarly, the NIHSS score follows an exponential distribution curve (depicted by 212). The hemoglobin measure and the creatinine measure follow the exponential distribution (depicted by 214) and the Gaussian distribution (depicted by 216), respectively.
Based on the distribution of the individual physiological parameters, a distribution of the copula is determined (as described in step 104). The copula is indicative of the joint distribution of the one or more physiological parameters. The copula distribution has been depicted by 220. Thereafter, based on the copula distribution, the Bayesian classifier is trained. The Bayesian classifier utilizes the joint probability distribution (determined from the copula) and the distribution of the one or more physiological parameters to classify the one or more patients in the one or more classes.
At step 302, a distribution of the one or more physiological parameters is determined across the patient dataset. In an embodiment, the one or more physiological parameters includes an age, a number of days between an onset of a stroke and a first medical consultation, a hemoglobin count, an RBC count, a creatinine count, a serum sodium count, a blood albumin count, a blood platelet count, or a complete blood count. The determination of the distribution has been described in the step 102. Additionally, along with the determination of the distribution of the one or more physiological parameters, the distribution of a stroke score is determined. In an embodiment, the stroke score corresponds to a score that has been assigned to the patient by the medical practitioner based on the measure of the one or more physiological parameters associated with the patient. In an embodiment, the stroke score is deterministic of a severity of the stroke. In an embodiment, the stroke score is an NIHSS score.
At step 304, a copula distribution, which is deterministic of the joint distribution between the one or more physiological parameters and the stroke score, is determined (as described in the step 104).
At step 306, a Bayesian classifier is trained based on the determined copula distribution (as described in the step 106). In an embodiment, the Bayesian classifier is capable of categorizing the one or more patients in the one or more categories based on the measure of respective physiological parameters. For example, the Bayesian classifier is trained to classify the one or more patients in one of the four classes (as depicted in the following table):
In an embodiment, an input, pertaining to the number of classes in which the one or more patients have to be categorized, is received from an administrator/medical practitioner. A person having ordinary skill in the art would understand that the scope of the disclosure is not limited to having only four classes. In an embodiment, the range of the stroke score can be further segregated to generate more than four classes.
At step 402, an input pertaining to a measure of the one or more physiological parameters is received from a medical practitioner. Prior to receiving the measure of the one or more physiological parameters, the medical practitioner examines the human subject. The examination of the human subject includes measuring the one or more physiological parameters using one or more sensors or blood work tests. Post determining the one or more physiological parameters, the medical practitioner inputs the measured one or more physiological parameters.
A person having ordinary skill in the art would understand that the scope of the disclosure is not limited to measuring the one or more physiological parameters by the medical practitioner. In an embodiment, the human subject may own the one or more sensors through which the human subject may himself/herself measure the one or more physiological parameters. Further, in an embodiment, the human subject may get the one or more physiological parameters measured from a pathological laboratory.
At step 404, a range of the stroke score is determined based on the measured one or more physiological parameters. In an embodiment, the Bayesian classifier is utilized to determine the range of the stroke score. As described in the flowchart 100, the Bayesian classifier is first trained on the patient dataset prior to determination of the range of the stroke score. The Bayesian classifier categorizes the human subject in one category from the one or more categories based on the one or more physiological parameters. In an embodiment, the category in which the human subject has been categorized is indicative of the range of the stroke score (refer table. 3). For example, if the Bayesian classifier categorizes the human subject in the class-2, the range of the stroke score is 11-20.
At step 406, the range of the stroke score is transmitted to at least a hospital authority. Further, the stroke score is transmitted to the medical practitioner. The medical practitioner may determine a severity of the stroke based on the category in which the human subject has been categorized. For example, as the human subject has been categorized in the class-2, the stroke is a moderate stroke. In an embodiment, following table illustrates the severity of the stroke versus the one or more categories:
Based on the severity of the stroke, the medical practitioner may plan the treatment of the human subject. For example, the medical practitioner may determine the dosage of the tPA medicine based on the severity of the stroke. Further, the medical practitioner may suggest admission of the human subject in the hospital based on the categorization.
The stroke score may be utilized by the hospital authorities to determine the type of care required by the human subject. Following table illustrates example actions that the hospital may have to take on receiving the stroke score:
In an embodiment, the care provided by the hospital authority may include, but not limited to, a treatment course for the human subject, an emergency care decision associated with the human subject, or a rehabilitation course for the human subject.
A person having ordinary skills in the art would understand that the scope of the disclosure is not limited to determining the stroke score for the human subject. In an embodiment, scores pertaining to various other health conditions such as Framingham risk score, and coronary heart disease risk score.
