mess with formal calculations every time a lab test comes back

This stuff seems too mathematical. No busy physician would have the time to mess with formal calculations every time a lab test comes back:http://gim.unmc.edu/dxtests/Basintro.htm

The sensitivity and specificity of a diagnostic test


The sensitivity and specificity of a diagnostic test depends on more than just the "quality" of the test--they also depend on the definition of what constitutes an abnormal test.
The paper titled as Applying the Revised Chinese JCQ to Assess Psychosocial Work Conditions in Taiwan’s Hospital Workers was completed in this month.

We know the ConQuest software to plot the multi-dimensional distribution of samples


It is amazing for us to know and learn the Rasch model's ConQuest software which can treat the multi-dimensional subscale using in health care.

Statistical data on internet released by Government

http://140.109.120.173/stat/stat.htm

In Taiwan we surfing webs on something about the statistical information on internet released by government, which can be used by researches and someone who are interested.
The information released on internet about the healthcare can be learned and transformed to the contries they need.

SEM to show the relation between variables and domains


SEM: structure equation modeling
Like the chart in the right sided hand,
The 40-ietm questionnaire can be shown in an ideal way.

using ConQuest to plot the multidimensionality


This is the mental examination in a hospital. We used the ConQuest software to analyze data and get the plot like that on right side hand.

A good idea to be brought out

When studing the Rasch model in designing scale, a wonderful idea was yielded.
Why we cannot design a scale for evaluating someone's ability about that using chopsticks.
Dr. Roberto was told to learn using chopstick in Taiwan. After practising it over many weeks and knowing it very well. \
Why we do not design a scale in evaluating abilities of persons and comparing it as well as obtaining a logit value of that ability level to reveal the result of practising chopstick in Taiwan.
That is also said that what is the performance of using chopstick by Dr. Roberto, which can be evaluated and brought back to tell his father what is the level of the performance. That is not only said I have known it. The amount of that performance results should be qualitified.

What is the main purpose when traveling study in Chi-Mei


We propose a flow to describe what is the main purpose when traveling study in Chi-Mei, which is from the beginning of wishing to know the medical quality to the end of that so-called foundation of medical quality: tools used via Rasch model.
Why? because that Rasch model can help evaluating, monitoring, predicting and detecting abnormal responses through fit statistics of quality control.

Quality indicator management to improve achievement ( Economic analysis on 4 quadrants)

We discussed on "quality indicator management to improve achievement", which was using the economic analysis to interprter it.

The effects are displayed with the areas of A,B,C and D, given the patient minimum requirement for quality on Line 1 or even upgrading to Line 2 which will let the area of A or B in term of the quality curve of C1 to be disappeared.
Therefore, as encountering the possible developement on patient's requirement upgrading all the time, we should be also takeing efforts on the quality(i.e. curve 1) to be upgraded as to curve 2 in a bit to let the advandage of competition areas to keep on existed.

In the analysis, the quality level will be decided by cost (investment), indicator management, custormers' satisfaction level(revenues of a hospital). That will be necessary for us to efficiently invest our efforts, money or time(X axis) on indicator management, which will then be let the performance of hospital revenue and custormers' satisfaction level higher and higher and eventually attain another higher level of quality curve as c2 in quadrant 1, which will also be allowing another newly-developed areas such as C and D ( so called Access) to be appeared.

The lesson on this analysis tells us that an efficient indicator management in a hospital plays an important role, not only for the suitable indicator we recruit but also for the analysis tools we implement. If then, the cost(on right X axis) we invest will be be a cost-effectiveness compared with the revenue (on left X axis).

A famous cronic desease hospital's health care to be visited

we have visited a hospital in charge of the cronic disease and feel impresive very much about its success.

Rasch and Continuous Variableshttp://www.rasch.org/rmt/rmt211.pdf
Question: Can Rasch analyze continuous response-level data, such as time and distance?
Answer: There are Rasch models for continuous observations, but processes are rarely truly continuous.
Rasch is formulated in terms of distinguishable qualitative advances.
How much better, faster, more accurate, does a performance need to be for it to be noticeably better?
Think of the same thing in human weight. Our weight varies all day long, so it is not until it has changed by 2 kilos that we really notice a difference. ( Just for the sample-average)
The basic approach in Rasch is to start by categorizing really begining increments.
If those are analyzed successfully, we can then reduce the size of the increments until we reach the level where further reduction introduces more randomness than information into the data.

There are several indicators of over-categorization.
One is that the model polytomous category probability curves start to look a mess, instead of an advancing range of hills. Another is that, as the number of categories increase, the sample-person “test” reliability falls far behind the value predicted by the Spearman-Brown Prophecy Formula.
Going from 2 categories (one decisioner item) to 3 categories (two decisions per item) is some
what like doubling the test length, but not so efficient.
So given the reliability, R(m), for an m-category rating scale, we would predict the reliability for an (m+1) category rating scale to be appreciably better, in the range:R(m) < color="#cc0000">keep track of the reliability as we increase the number of categories. When reliability not longer shows a reasonable increasing (or starts to decrease) we have overcategorized. John M. Linacre

quality control technique required to supervise and validate test items andperson responses.

The analysis of fit evaluates how well our data cooperate with the construction of measurement.
Analysis of fit gives us a tool to monitor the responses of persons anditems .
We can evaluate any set of items or persons to determine wheremisfit occurs .
Fit analysis provides the quality control techniquerequired to supervise and validate test items andperson responses.
When fit is within our guidelines, we have the control required to feel confident about item calibration and person measurement.
When misfit is discovered we can locate its occasions and begin further study of the items or persons involved.
The analysis of fit is never completed because continued use of the instrument requires that we constantly monitor item and person responses to maintain quality control .

Many physicians in Chi-Mei can speek spanish language...

We have met several physicians in Chi-Mei who can speak flunt spanish. Dr. Roberto have had a chat with them. A very delight experience that is remeriable has kept in my mind...

BSC comparing performances using many-faceted Rasch model


A paper of "Comparisons of Hospital Balanced Scorecard Performances Using Many-Facet Rasch Model: Predict and Detect" was reviewed.

We know that the balanced scorecard (BSC) has been implemented worldwide in every hospital. Many executives are encouraged to compare, and even predict or detect performances WITHIN and BETWEEN hospitals year by year.

The many-facet Rasch Model (MFRM) could be applied to analyze BSC data.


The same scenario can be designed as the indication management for assessment on examinees, judges and items, which are inspected and monitored periodly and continuously to let medical quality upgraged through the process of learning, practising and habit-shapping.
A picture is worth a thousand words is a proverb that refers to the idea that complex stories can be described with just a single still image, or that an image may be more influential than a substantial amount of text. It also aptly characterizes the goals of visualization where large amounts of data must be absorbed quickly.



Innovative job descriptions


We talked about the job description and how to design the employees' role and directions of future learning. An innovative way regarding the talents for employees is proposed and dicussed.
"Amazing" was the answer and response from "Dr. Roberto".

A graphical health report constructed as a KIDMAP Using Rasch Analysis of IRT Mode

The new issue that generates a KIDMAP for a graphical health report is for us a flash experience to know the quality improvemnet when adopting an appropriate approacht to measure them. The topic will encourage us to know even the health examination can be investigated and compared with each other so as to improve them.
A proverb tells us that an improvement is always derived from a comparison..
Good luck and have a nice learning process.....

Rasch analysis of Picker 2004 Questionnaire

"Rasch analysis of Detecting Most Unfitted Items on Questionnaire of Picker Institute: Outpatient Survey for 2004" is our research material recently which helps us know more about the data analysis and report generation.
How to conduct a survey for quality improvement is an important issue. We will indeed have the chance to pratice it ones more again....

A Survey of the prevalence of thoracic scoliosis in Taiwan

Objective: Survey the prevalence of thoracic scoliosis through the chest x-ray examination of labor’s annual health.
Using univariate logistic regression was found that, the odds ratio for female was 2.61(95% CI: 1.93-3.51), old age and obesity (BMI>27) had protective effect.
We can see that a study of surveying some regarding the chest x-ray examination of labor’s annual health is a interesting matter in healthcare.
If we could use another method like somehow the Rasch analysis to examine the abnormal interactions on items and persons, a newly developped resarch may be devived from that would-be published paper we have read in this week.

maximum likelihood estimate

We talked about the MLE. Maybe it seems somewhat difficult for us to explain the real meaning of MLE, but there are several examples we used to let us know that made it easily undetstood.
Note that the maximum likelihood estimator may not be unique, or indeed may not even exist.

Maximum likelihood estimation (MLE) is a popular statistical method used for fitting a mathematical model to some data. Modeling real world data by estimating maximum likelihood offers a way of tuning the free parameters of the model to provide a good fit.

For examples, you are willing to assume that heights are normally distributed with some unknown mean and variance. The sample mean is then the maximum likelihood estimator of the population mean, and the sample variance is a close approximation to the maximum likelihood estimator of the population variance

In Taiwan, any one can check the record which they had seen the doctor on internet if they have the card of MOICA Certification






More informationfor detail at http://moica.nat.gov.tw/html/en/index.htm
http://moica.nat.gov.tw/html/matter/9707/index.htm
Because in Taiwan, evey persons almost are recruited in the system of heatlh care coverage. any one who have seen the doctor will keep the record in hospital computer and then check it on internet to see how much money had been reibursed or claimed by that specific hospital or other related informaiton by means of a so-called MOICA card issued by the Taiwan government.


Who should be concerned for abnormal item responded by the examinee...

1
Chest X-ray; 2Urine dipstick; 6 triglyceride; 4 hematin; 9 SGPT; 3 WBC; 5 cholesterol
7 blood sugar; 8 Creatinine

As for the service lenght in the hospital, the yougest needs to care for SGPT
For age, aged employees not well on Creatinine(8), yongest ones well on X-ray

For gender, Urine dipstick happened onto Female,but SGPT not well onto Male.


SGPT of physician performed not well, but surpassed on Urine dipstick






Under the condition of patient privacy, we render the service of most unexpected response report disclosing the item to be rechecked or concerned for further examination....







any difference between groups for health ability?

difference in
difference in service length for the hospital

No difference in age No difference in gender...






No difference in dept, i.e., administration, nurse, technician and physiscian.




Aug/ 10 will be the date of presentation for telling them what I have known in Chi-Mei

1> describe the Web-blog and introduce what I have veiw in Chi-Mei
2> the referring system for making appointment which can be adopted in Nicaragua whithin 2 years.
3> coorporation with hospitals between the two contries vis internet meeting of which we will connect to Nicaragua at 9:30
4> the health examination using Rasch analysis will be introduced in that presentation which will let the employees know the measurement plays a vital role while implementing the health promotion in an organization. We will also compare the group health status with each other in a hospital. Very interesting is it in that presentation date...
Date: Aug. 10
Time: 9:00 - 10:00
Participants: employees of Chi-Mei who interested in that topic.

7/26-7/30 course: Kidmap for health report of employees using WINSPEPS Rasch analysis








We will plan to research on the health report and analysis of a hospital's employees using Rasch analysis to know if the health statuses of them are good or not. It is of interest for us to introduce the method to others and to let a hospital to implement the health promotion.
Aug. 10 will be the presentataion date. Next week will be excise it and know how to run the data and interprete the reports.

weekend in Tai nan



two fabulous days, I went to pick up stones with Mr. Ke and his fammily. He brought us, to a National Park in the mountains. Impressive, how they take care of Nature, also their tolerance. Mrs. Ke is so nice, she was too kind to us.
