It will be realized that Fig. 1 illustrate only this aspect of the diagram disclosure needed for component, and in actual embodiment In, system 100 may include the additional components other than those of shown component.For example, system 100 may include being used for The battery or other power supplys powered for system 100 or the device for system 100 to be connected to main power source.
In more detail, as mentioned above, system 100 is configured for assessment performance data.Memory 106 includes table Show the director data of the set of instruction.Processor 102 is configured as that the set of described instruction is communicated and executed with memory.Letter The set of Yan Zhi, described instruction make processor 102 when the execution of processor 102 by system 100: acquisition is related to performance indicators Multiple performance data records of connection;Classified according to the performance indicators to each performance data record;Identify the performance Multiple variables of the classification are contributed in data record;It is determined based on the multiple variable and performance indicators and described The relevant multiple observation results of at least one variable in multiple variables;And the multiple observation result is delivered for being presented to User.The observation result be considered " it was found that " and can referred to as " it was found that ".For example, observation result (or discovery) It is considered the result based on the analysis to performance data.
The performance data record can be related to any kind of activity or performance of task previously executed.With this side Formula, the performance data record may be considered that including history or passing data.Each performance data record can for example be related to Single-unit activity or task and/or it is related to special entity.For example, each performance data record can relate in health care environment And movable or task performance relevant to particular patient.Fig. 2 shows the multiple performance data records being disposed in table 200 Example.In this example, every row in table 200 is related to the process for the particular patient for being numbered as 1 to N.In table 200 Each column includes and is related to performed process and/or be related to and executes the associated number of the particular variables of patient of process about it According to.Column 202 indicate the gender of patient (' M ' is used for male, and ' F ' is used for women);Whether column 204 indicate patient by certain medical Situation, in this case, the specific medical conditions be diabetes (if patient really by the medical condition, for ' Y ', if it is not, then being ' N ');The age of the instruction patient of column 206;Process relevant to patient is responsible for or is executed in the instruction of column 208 Consulting staff cognizance code or number;Column 210 indicate the waiting time of patient (that is, being placed on from patient with process Waiting list on duration on date for being performed to the process on date for waiting).In other examples, the waiting Time can be variously defined.
It will be realized that may will include than more data records shown in table 200.In some examples, data Library may include hundreds of or thousands of performance data records.For example, database may include being related to and entire hospital or healthy group The record of the relevant performed all medicals of the patient knitted.Furthermore, it will be appreciated that the amount of available data is depended on, Each data record may include more or fewer data (that is, table 200 may include more or fewer column).For example, number According to library may include the instruction of the type of performed process, the instruction of the priority of the process (for example, the process whether Optionally executed or patient be that the process is awaited orders), the instruction whether disposed privately of patient is (for example, at as payment The part set), the instruction of medical facilities that is disposed of patient etc..
Each performance data record is associated with one or more performance indicators.In example shown in Fig. 2, the table Existing data record is associated with the performance indicators for involving waiting for the time.Specifically, the performance indicators involve ensuring that patient etc. Wait be longer than the target or expectation of the time (for example, six weeks) for the definition being directed in the waiting list of process.If process is defining Period in be performed, then the specific condition can be considered having met or having met the performance indicators.However, if stream Cheng Wei is interior at the defined time period to be performed, then the specific condition is not considered having met or having met the performance indicators.Such as Mentioned above, performance indicators can be referred to as crucial performance indicators (KPI), and these indexs can for example be used to comment Estimating special entity, company or tissue, to meet one group of guide how well.
In some examples, performance data record can be associated with multiple performance indicators, so that the data record can Performance is assessed be used to compare multiple performance indicators.For example, data record can be showed with involve waiting for the time first Index and be related to process has how successful second performance indicators associated (such as in example above in the case where disposing specific medical conditions In).In this example, the data record can be used to assess the success of waiting time and/or process.
Once the performance data record has been collected, described instruction just makes the processor 102 of system 100 according to described Performance indicators classify to each performance data record.The classification of each performance data record can be and classified based on two-value Mechanism, thus if meeting specific criteria (or one group of standard), data record is classified as meet the performance Index, and if being unsatisfactory for specific criteria (or one group of standard), it is classified as not meet the performance indicators.It is above In the example discussed with reference to Fig. 2, whether each data record (1 to N) can meet the requirement about the waiting time according to it To classify.For example, if the waiting time of greatest expected is six weeks (that is, 42 days), in data shown in Fig. 2 In, data record 1,2, N-1 and N may be considered that and met the waiting time standard, because its waiting time is both less than 42 days, and data record 3 and 4 may be considered that and not meet waiting time standard, because its waiting time is longer than 42 days.
In some embodiments, performance indicators associated with each performance data record can be transformed into classification type Or rule.Therefore, in such embodiments, the set of the described instruction in memory 106 is stored in when by processor 102 The processor can also be made to generate the classification standard for being directed to the performance indicators when execution.As above, the classification standard can To be two-value classification, such as according to whether meet the standard to classify.For example, the classification standard may include about Whether the instruction of the performance indicators is met.In some embodiments, the performance indicators can be transformed into classification standard, make Obtaining data record can be according to whether there are problems that classifying about the classification standard (that is, problem or worry).Example Such as, it if data record meets classification standard (for example, the waiting time is less than the duration defined), can be classified The problem of having ' N ', being not present with instruction about the specific criteria;However, if the data record is unsatisfactory for classification standard (example Such as, the waiting time is longer than the duration of definition), then it can be classified ' Y ', exist with instruction about the specific criteria The problem of.
For example by medical professional each record can will be distributed to the classification of data record or by responsible Consulting staff is manually done after process, such as rule-based automated procedure can be used and be automatically completed.? In some embodiments, classifying rules can automatically be speculated according to data.For example, such as information gain cut-off and/or cluster Technology may be used to determine whether each data record meets classification standard.In one example, passing performance data Record is stored with particular order (for example, with sequence of the waiting time of rising), and mean shift clustering method is applied To find the turning point in data.Recording those of on turning point will be classified as be unsatisfactory for the contingency table for performance indicators Standard, and record will be classified as meet the classification standard those of under turning point.In some embodiments, contingency table Standard, such as maximum latency can be determined based on the requirement illustrated in one group of guide.In some embodiments, machine Device learning art can be used to automatically determine classification standard or rule.
For performance indicators come determine classification standard embodiment in, make the processor to each performance data record Carrying out classification may include that the processor is made to be classified according to the classification standard to each performance data record.
In some embodiments, update can be provided for user or change performance indicators or differently described point of definition The option of class standard.For example, user can update institute in the case where the classification standard requires process to be performed in six weeks Standard is stated to require process to be performed within the different periods (such as surrounding).
The instruction being stored in memory 106 also makes the processor identification performance number when being executed by processor 102 According to the multiple variables for contributing to classification in record.In the performance data record, there may be the multiple changes for contributing to classification Amount (such as, if meet the performance indicators).In the example that reference Fig. 2 is discussed, whether specific process is being wanted Any variable being included in data record can be depended on by being performed in the waiting time asked.For example, being directed to specific condition Be not able to satisfy the target latency time can with the gender of patient, with patient whether by specific medical conditions, with the age of patient, To the consulting staff for being responsible for the process or related with any other factor or variable that can be included in data record Connection.Some variables, the gender of such as patient, it is impossible to have strong tribute to whether the process is completed within the target latency time Offer influence.However, its dependent variable, is such as responsible for the consulting staff of the process, relatively strong influence can have.Such as institute above It mentions, hundreds of or thousands of (or even more) a data records can be collected and be evaluated, and each data are remembered Record may include tens of or hundreds of data fields, wherein each data field in the data field may be constructed about Whether the variable or contribution factor of classification standard are met.In addition, if there are other contribution factors, then some contribution factors can be with More strongly contribute.For example, specific consulting staff can contribute to the longer waiting time, but only when the certain types of stream of execution Cheng Shi, or only when executing process in certain medical facility.It is thus impossible to which enough manually interpret all data and establishment Which variable most contributes to specific classification by force.
In some embodiments, processor 102 is made to identify that the multiple variable may include that come from the processor will The data of multiple performance data records are supplied to one or more prediction models.Various prediction models can be used, to identify Show the contribution variable in data record.In some embodiments, can be used machine learning model, such as neural network and/ Or deep learning network.In some embodiments, identify that the multiple variable may include using one or more mode discoveries Model, decision tree, rule generate model, and/or maximum information gain model.The performance data are recorded in it and have been classified It can be fed in one or more prediction models later to be trained to the model.In this way, the mould Which variable is type can learn or which kind of combination of variable most contributes to specific classification by force.For example, the model can learn Which factor most contributes to satisfaction (or being unsatisfactory for) waiting time target by force.
Various data processings and data analysis technique can be used to analyze the output of the data from various prediction models, with Just determine which prediction model identifies the variable most contributed by force.Including ' area below recipient's characteristic working curve ' (AUC) prediction performance measurement can be used to assess the prediction model.AUC measurement instruction covers more true targets and introduces Tradeoff between more vacation candidates.Cross-Validation technique can be used for the measurement of more various prediction models.Specifically, exist In cross validation, partial data is taken out, and the rest part of data be used to construct prediction model.Constructed model is then It is used to compare taken out data and carried out prediction.The prediction is compared with the actual value of the performance indicators, in terms of Calculate the prediction performance measurement.
According to the analysis of prediction model and the output of prediction model, which prediction model optimum prediction can be provided about Performance measurement is determined (according to the variable for contributing to classification).It is then possible to select to be confirmed as providing the pre- of optimal representation It surveys model, and may be used to determine whether as discussed below associated with the data one by the variable that the prediction model determines A or multiple observation results.
It may include some changes for contributing to carried out classification by force by multiple variables that optimum prediction model identifies Amount and some variables for not contributing to carried out classification by force.Therefore, in some embodiments, can execute to variable Further analysis so that variable is included in short-list, and identify which variable is most related.It is described more in some examples Each variable in a variable can be compared with each of the multiple variable its dependent variable (for example, changing on it Generation).
By the analysis or filtering according to one or more measurement, it can quantitatively reduce the multiple variable.Due to Comparing each variable and its each dependent variable may be large-scale and data-intensive task, therefore in some embodiments In, the system can reduce comparison task by limiting the quantity of compared variable.Can about when and its dependent variable Which variable may provide most useful information and be determined when comparing.Such determination for example can be by analyzing previous user Behavior, passing analysis record are (that is, result of the similar data analysis technique previously executed) and/or relevant to performance indicators Document (for example, guide) Lai Jinhang.Such as when analyzing the waiting time, prediction model can indicate the consultation of doctors for being responsible for the process Doctor is about whether the strong contribution factor for meeting performance indicators.Divide according to passing KPI data relevant to the waiting time Analysis, the system can speculate that the period of season and the moon are especially relevant when considering the waiting time of consulting staff.Institute The system of stating can also speculate that the type for the process to be performed is the notable contribution factor to the waiting time.When it is to other It is continually investigated then, such as this can be speculated in the analysis of KPI.Therefore, in this example, the system can be with For every consulting staff in terms of being broken down into its serving-time distribution of season and the moon and performed process class Data are analyzed in terms of type.
In one embodiment, all text elements of variable associated with performance indicators and/or guide can root Recorded according to passing performance data record analysis of history, and maximally related variable can be identified as relative to The variable that its dependent variable is further analyzed.In other embodiments, all unique values of variable can be transformed into item I1, I2, I3 ... IN }, wherein performance indicators continuous item (such as classification standard) is subset { I ' 1, I ' 2, I ' 3 ... the I ' of the item K }, wherein k < N.Frequent item set mining can be used to identify the item frequently occurred with performance indicators continuous item.In other realities It applies in example, " word2vec " method can be used for the user for identifying that expression is registered as performance indicators continuous item and background item The term vector of the distributional semantic model of behavior and the term vector of other performance indicators parsing.It shows close with performance indicators term vector The activity and/or behavior of similitude can be identified as the variable for further analyzing.
By analyzing passing performance data record, the performance trend with the time can be identified, allow user's energy Whether enough activities of rapidly saying and the performance of task are totally improving or are deteriorating.Such understanding can permit about in table The particular variables identified in existing data record are made decision, such as so that the performance of difference is enhanced.
In example above, the determination for the variable that be compared with one another and be analyzed is by being made by the system Decision automatically carry out.However, in some embodiments, user can choose the change that be compared with one another and be analyzed Amount.For example, in some embodiments, user be considered that the age of patient may contribute to by force for execute process etc. To the time, and therefore, before its dependent variable is put into short-list and is analyzed, user can choose patient age work For strobe utility.
It is intended to reduce the size for the data set to be analyzed to the analysis that the multiple variable executes, so that the analysis can To be performed faster, and to require less process resource.This data analysis can be referred to as " alternate analysis ", by This big data set " being sliced " and " dicing ", to assess particular variables relative to its specific dependent variable, but are not necessarily to Consider all variables in data set.
In some embodiments, certain variables may seem to contribute to by force specific classification (for example, particular variables can be seemingly Lead to the longer waiting time), but there may be why these variables are contributed by force and these variables are inevitable The reason of.For example, specific process can the process be need to performed before one month period patient view's result.? Under such circumstances, process can be requested, particular patient is made to be added to waiting list, but since patient must be observed knot Fruit one month, necessarily it can be extended one month for the waiting time of the process.In this case, wherein tribute The factor of offering be inevitable and be it is known, can be ignored or for the contribution factor of variable by from analysis It removes.
In some embodiments, multiple performance indicators can be interested, or can be relevant.In such model Example in, the system can provide multiresolution analysis, wherein variable associated with a performance indicators can relative to Another associated variable of performance indicators is analyzed.
Therefore, it is however generally that, the instruction being stored in memory can make the processor when being executed by a processor The multiple variable is filtered according at least one measurement.In some embodiments, at least one measurement may include using The measurement that family defines.As mentioned above, the big of the data set to be analyzed will be reduced by being filtered to the multiple variable Small, thus reduction analyzes the data and determines time and the processing capacity of the observation result.The multiple variable can be with The one or more measurements being filtered according to it automatically or by user are manually selected by the system.As solved above It releases, the measurement can be based on its dependent variable, and such as, such as whether the process is optional process, about its execution The age of the patient of the process, the hospital for executing the process or facility etc..Variable is filtered can make user from Removed in data set it is incoherent, useless in assessment, and/or be considered it is trifling (for example, in classification be not it is important because Element) data.
Filtering can be used to reduce the size for the data set to be analyzed, to include and be considered most contributing to point by force The relevant data of the variable of class.In some embodiments, be filtered to variable may include using baseline or threshold value;It drops to Variable can be ignored from analysis or omits those of under baseline or threshold value, and variable can those of on baseline or threshold value To be included in analysis and further be considered.In some examples, the baseline or threshold value can by user setting, and And for example may include statistically significant p- value or the variable to be considered number of thresholds.
Once performing analysis to the multiple variable, the variable just for example can be in the contribution made to classification Sequence in terms of classify.For example, be confirmed as most by force contribute to classification those of variable can be ranked as height In be confirmed as on classification almost without contribution influence those of variable.The variable of highest level is (for example, the first 10 most contribute Variable) it is used as from the subset of the variable of result from its determination.In some embodiments, the subset of variable can be with one A little other modes (for example, using baseline as discussed above or threshold value) determine.
The instruction being stored in memory make when being executed by a processor the processor based on the multiple variable come Determine multiple observations relevant at least one variable in the performance indicators and the multiple variable as mentioned above As a result.In some examples, the observation result can the subset based on the variable for using method as described above to establish come It determines.Observation result discussed herein is considered following opinion, because the observation result provides pair for user The slave initial data for the data being analyzed is to user's not obvious opinion immediately.
Observation result is considered the summary to the data analyzed, and allows users to infer about being considered Data the most important and related fact.For example, in the case where discussing herein, wherein analysis is directed to various meetings Examine the waiting time of doctor, wherein the waiting time is broken down into week and season, and observation result is confirmed as and specific consulting staff C03 is related.According to an example, the system can determine the observation of " C03: 6.1,6.4,7.2 weeks average to Q2, Q3, Q4 " As a result.In other words, it is determined during season Q2 based on the data analyzed for the specific consulting staff with identifier C03 Waiting time be average 6.1 weeks, the waiting time during season Q3 be averaged 6.4 weeks, and during season Q4 etc. It is 7.2 weeks average to the time.In another example, wherein for every consulting staff waiting time about process whether be Option program (that is, patient chooses with the process, rather than the process is ordered by medical professional) Lai Jinhang is commented Estimate, system can determine the sight of " C15 average 6.2 weeks in optional priority, other are in the range from 3.2 weeks to 5.8 week " Examine result.In other words, for the specific consulting staff with identifier C15, determine that the waiting time for optional process is flat Equal 6.2 weeks, and for other (non-optional) programs, the waiting time is averagely between 3.2 weeks and 5.8 weeks.Although only give herein Gone out the observation of two examples as a result, it will be appreciated that, the system can be determined based on many variables it is many observe as a result, And it is decomposed with being permitted various ways.
In some embodiments, the instruction in the memory can make the processor when being executed by the processor It classifies before delivering the multiple observation result for presentation to the multiple observation result.The observation result can be by Graduation, or the subset of observation result can be identified or be selected by considering the statistical significance of the observation result.Cause This, making the processor may include that the processor is made to calculate each observation result to the graduation of the multiple observation result Statistical significance.In some embodiments, the set of described instruction can make the processor when being executed by the processor It is classified according to statistical significance calculated to the multiple observation result.For example, being considered to have relatively higher statistics The observation result of conspicuousness can be ranked as higher than the relatively lower observation result of its statistical significance.In some examples In, p- value (that is, probability value) can be used to measure in the statistical significance for observing result, and thus lower p- value instruction is bigger Statistical significance.In some embodiments, the statistical significance (for example, p- value) can together with the observation result by It is presented to the user.
It in some embodiments, may include the scoring system according to definition to the multiple graduate process of result of observing System scores to the embodiment.Maximally related observation knot is considered with those of highest score observation result Fruit, and therefore, it can be ranked in the list of the multiple observation result higher.The observation result of these greater degrees It is considered " primarily observing result " or " primary opinion ".In some embodiments, it is ranked in baseline or threshold value water Observation result or scoring are less than those of threshold quantity observation result and can be saved in any other analysis those of under flat Slightly or it is ignored.
In this way, the system can be considered dividing priority to observation result, and in position more outstanding In presented (that is, higher in graduate list) for user there is those of higher priority to observe result.Higher priority Observation result be given more weights because these observation results can be used by a user in carry out it is relatively small change so as to Improve activity relevant to performance indicators or the aggregate performance of task.For example, if result is apparent from high priority Be waiting time of specific consulting staff gradually to become longer within recent months, then it can indicate consulting staff Workload it is too big.This may not be from initial data immediately it will be apparent that particularly in view of that can have to the waiting time The every other variable influenced.By providing this analysis for user, user can take any necessary operation to change Kind waiting time performance, such as the workload by reducing consulting staff.Family is not used only and more readily identifies any performance for this Related problem, and enable other potential problems processed (for example, the workload energy of consulting staff in early stage It is enough to be contracted by before it becomes too big).In addition, by the quantity of reduction variable (for example, by filtering, dividing priority And graduation), it to be contracted by by the data volume that processor is analyzed, thus reduce processing load and calculate the time.
In other embodiments, other technologies can be used to classify in the observation result.For example, the system can be with For the error of the classification of each variable analysis data record in variable relevant to performance indicators.Based on minimum quantity Those of variable observation result of missing classification can be used as preferred (greater degree) observation result and be put into candidate name It is single.
In other embodiments, it can analyze and have been classified as being unsatisfactory for specific mark associated with the performance indicators The subset (for example, having been classified as that there is those of " problem " to show data record) of quasi- performance data record, and can With counting accuracy and sensitivity.F- score (that is, harmomic mean of accuracy and sensitivity) or g- mean value (that is, sensitivity and The geometric mean of specificity) it can be calculated for each performance data record in subset, and there is highest f- score The record (for example, those of f- score or g- mean value on threshold value with definition data record) of (or g- mean value) can be by It is included in short-list.It can be used as preferred observation result quilt with those the associated observation results that record for being included in short-list It is included in short-list.
