A method and system for analyzing the durability of a patient placed for therapeutic purposes

Area

The present invention relates to a method and system for analyzing the durability of a body to be placed in a patient for therapeutic purposes.

Background In medicine, various pieces of a patient are placed in a patient for therapeutic purposes. Such items include, for example, dental fillings, dental implants, dental masses, dental crowns and dentures. In the medical field, for example, the following may be mentioned: an artificial joint, a bone screw, a bone nail, a prosthesis, a silicone prosthesis, a heart valve, a pacemaker. The piece may also be another piece of treatment used for permanent or temporary placement in an animal or human.

15 For example, in the field of dentistry, the materials industry is producing new fillers and other materials at an accelerating rate. Up to yearly replacement products are now possible. Tooth fillers, though. * ·: Are permanently placed in the body, but are counted out of the body,: Y: therefore they do not require normal medical testing prior to commissioning. The utility of various materials is nowadays most often tested in trial-type experimental conditions, whereby the actual utility is only known afterwards in normal clinical work. Look here, ···. for reference, P.J.B. Leemboel, M.A. Van't Hof and F.J. De Haan:

Survival studies of dental restorations: criteria, methods and analyzes. Journal 25 of Rehabilitation 1989, Volume 16, pages 387-394. Actual working • •; [: there is therefore no beach.

The principle of clinical research is to achieve, as early as possible, a categorization that is as accurate as possible; the stage is able to register possible failures. Thus, for example, in the caries / 30 caries, there is talk of initial caries, stagnant caries: “and remineralized caries. At these stages, the dentist will monitor: "whether the caries are progressing to the extent that it may require treatment. On the material side, for example, implants may have significant bone loss after the first two years, which then stops. with scientific follow-up, it j 2 109243 would seem to have failed. See T. Albrektsson and GA Zarb for reference, Current Interpretations of the Osseointegrated Response: Clinical Significance, International Journal of Prosthodontics 1993, Volume 6, pages 95-103.

5 In clinical practice, caries have certainly improved when the dentist makes a point. See M.A., incorporated herein by reference. Larm, J.l. Virtanen, R.S. Bloigu: Timing the First Restorations in Permanent Teeth: A New System for Oral Health Determination. Journal of Dentistry 1995, Volume 23, Number 6, pages 347-352. Likewise, the implant or site 10 will certainly have failed only when it has to be removed from the mouth. See I.A., incorporated herein by reference. Mjör, J.E. Dahl and J.E. Moorhead: Age of Restoration at Replacement in Permanent Teeth in General Dental Practice. Acta Odontologica Scandinavica 2000, 58, pages 97-101.

In practice, these clinical failures are distinct from the scientific failures.

In Europe, there are less stringent requirements for testing the usability of fillers as for, for example, pharmaceuticals, although manufacturing processes and products are audited by various rating agencies, for example, for toxicity. . before the CE marking was granted. Follow-up of endurance::: 20 comes with a trial-type trial design and, for example, a new filler for ADA (American Dental Αεί '·' sociation) approval will only be obtained after 5 years of research on endurance monitoring by ADA approval. way.

:: In practice, an ADA-approved product may have been withdrawn from the market and: ": replaced with a new product before it has even been approved.

Thus, the durability of fillers is tested in a trial type.

Trial studies often use Kaplan-Maier statistical analytical methods. Although excipients are not required for the type of pharmaceutical product good clinical ···. practice applied research, the results of large trial runs are long delayed and expensive to implement. In addition to trial-type studies ..: '30 is associated with '' calibrated researcher 'problem. Researcher calibration implies that: a researcher should always be able to perform a certain procedure in the same way, for example, tooth replacement always as well. In practice, this is almost impossible, whereby the researcher's non-calibration causes his or her own difficult to estimate error in the trial.

35 Thus, according to the prior art, nursing activities produce statistical health information in the form of so-called. status, which describes the current state of health, and de- 109243 cursus, a description of care as a daily procedure. In dentistry, health information is currently compiled into individual indexes such as DMF and DMFS. Similarly, research will collect new health information using, for example, Kaplan-Meier analysis and develop new ti-5 pediatric analysis and imaging models. Material Research conducts multi-year triads, often multi-center studies, that track product life cycles. Nursing and research are completely separate entities.

BRIEF DESCRIPTION OF THE INVENTION It is an object of the invention to provide an improved method for analyzing the durability of a patient placed for therapeutic purposes and an improved system for analyzing the durability of a patient placed for therapeutic purposes. In one aspect of the invention there is provided a method according to claim 1 for analyzing the durability of a patient insert for therapeutic purposes. In one aspect of the invention, there is provided a system according to claim 8 for analyzing the durability of a body to be placed in a patient for therapeutic purposes. Other preferred embodiments of the invention are claimed in the dependent claims.

. ! The invention is based on the fact that, in addition to the trial study, the durability of paragraph 20 is followed, after its introduction, by utilizing normal • | farm care.

List of figures

Preferred embodiments of the invention will be described by way of example with reference to the accompanying drawings, in which: Figure 1 illustrates a system for analyzing the durability of a patient insert for therapeutic purposes; Figure 2 shows the user interface of the system of Figure 1; Figure 3 shows the status markings; Figure 4 illustrates a simplification of status markings; Figures 5 and 6 illustrate performing a Survival analysis; Fig. 7 is a flowchart illustrating a method for analyzing the durability of a body placed in a patient for Hoi An purposes.

Description of Embodiments

Referring to Figure 1, a system for analyzing the durability of a patient placed for therapeutic purposes is described. System 15 comprises at least one computer-implemented patient information system 100, 102, 104 for monitoring and billing for treatment management of a unit placed on a patient for therapeutic purposes, and cap. . to record the effect of the burn on the patient. Figure 1 shows clarity; therefore, only three patient information systems 100, 102, 104 are described, but in practice, there may be a very large number of patient information systems, for example. ·: Thousands or tens of thousands.

:. * · · The effects of the paragraph are preferably status markings of the patient's medical record stored in the patient information system 100, 102, 104. An increasing proportion of the medical community is or is in the process of moving to electronic medical records.

·. : For example, there are hundreds, ··· [different methods of registering dental health as a part of patient care in digital form in dental status worldwide. What all these clinical-routine methods have in common is that the state of the tooth in a healthy, carious or patched state is encoded in digital! in terms of. These dental statuses can be followed by changes in dental health from tooth decay to salary decision, for example, with scientifically acceptable accuracy, even though health research is done by a "non-calibrated" clinical dentist, if the number of status is large and many.

109243 5

All patient information systems 100, 102, 104 track patient billing and statistics operations, most often coded daily. These essential patient records are monitored for patient billing and / or procedure statistics, and are not intended for scientific analysis according to prior art 5, nor have they been used for scientific analysis.

In the system of Figure 1, the decuration of patient care, i.e., a list of procedures for patient care, is used to monitor in real time the persistence of tooth fillings or other structures on a single tooth and / or tooth surface. On the one hand, it is monitored when a piece needs to be repaired in one way or another, and on the other hand when a piece has to be permanently replaced. Thus, by monitoring the changes in the status markings and procedure entries of the individual patient record in the patient information system 100, 102, 104, the durability of paragraph 15 can be reviewed.

Figure 3 shows the status registration. The teeth are coded according to common practice by dividing the teeth into upper and lower teeth. The upper and lower teeth are then divided further to the left and right of the centerline. . side teeth. Viewed from the front, the upper left is; .: 20 first block, upper right second block, bottom right third block, and lower left block 4. The teeth are numbered in each block starting from the middle stone. That is, the front teeth are 1 and 2, the incisors 3, the intermediate teeth 4. '·: and 5 and the canines 6, 7 and 8. Since a person has a maximum of 32 teeth (including wisdom teeth), the last figure is the wisdom tooth 8.

25 The tooth can now be referred to as a number formed by a block and a tooth number. For example, 11 is the first tooth to the left of the middle stone tooth to the left, and 41 is the opposite lower tooth. from the center line to the left. Table 1 describes the codes for the teeth.

•: i '18 17 16 15 14 13 12 11 21 22 23 24 25 26 27 28: I 48 | 47 I 46 l 45 | 44 | 43 l 42 | 41 l 31 | 32 l 33 l 34 | 35 | 36 l 37 | Table 30

Fig. 3 depicts the seven teeth 11, 12, 13, 14, 15, 16, and 17 on the left side of the upper jaw, which are missing from the patient because they have not either erupted or been removed to avoid problems.

The tooth has four or five surfaces. The front and corner teeth 11, 12, 13 have four surfaces: a first side surface 302, a second side surface 304, a third to a side surface 306, and a fourth side surface 308. The rear teeth 14, 15, 16, 17 have four side surfaces 302, 304, 306, 308 in addition to the chewing surface 300. The front and corner teeth 11, 12, 13 do not have a chewing surface 300, but are thought to have only a pu screw or a chewing point.

j The horizontal axis of Figure 3 illustrates the condition of each tooth at a specific time point. When the surface 300, 302, 304, 306, 308 is not marked, as in block 310, then the tooth is healthy. For example, tooth 12 is healthy on all surfaces at all six inspections 0, 1, 2, 3, 4, 5.

The first patch of the tooth is the "" birth ", i.e., the tracking al-15 bullet, which is recorded on the surface on which it is" born "using the vertical line described in block 312. For example, the first side surface 302 of the tooth 11 is provided with a location at the first inspection. Similarly, at the first inspection, for example, a tooth is disposed on the chewing surface 300 of the tooth 17.

·,; As long as the marking remains unchanged, the tooth will retain its "birth" state, that is, its first position until the follow-up time runs out; \ c leads to "censorship" of tracking.

• If the tooth filling is replaced with a new one, this is "event 1", "* i, which is illustrated by the change from a vertically lined block 312 to a cross-lined block 314. In principle, you may need to repeat more than 25 times; For example, the filling of the bite surface 300 of the tooth 17 is replaced: first with a new filling in inspection 2, and a second time with a new one. '. I make the stuffing at inspection 4.

If the tooth filling falls off, this is '' event 2 ''. In this case, the j 30 tooth returns to its hole space, unless it is immediately repainted. Figure -...: in section 3, this is described as having previously been line-lined or cross-lined; the surface becomes white. For example, tooth 15 is patched on inspection 3, ....: on inspection 4 the filling is still in place, but then on inspection 5 the filling has fallen off. If the tracking ends with Event 2, censorship 35 is marked as this event, which is counted in the statistical calculations as a censored event with a zero tracking time.

109243 7 This per se complicated data registered in dentist status charts is reduced to simple event data in a preferred embodiment by recording only changes that are obtained directly from the procedure list by day or from the Revision Check status as shown in Figure 4. The change is, for example, the placement, resettlement, or termination of the item in the patient. This will greatly simplify the enormous amount of data registered in successive status charts. This is clearly evident when comparing Figures 3 and 4 with each other. Unchanged fillings are removed from the file. Only changes, ie first 10 patches, refills, or drips, are recorded.

For example, the changes of tooth 17 are: filling birth 400 for puff surface 300 in inspection 0, filling replacement 402 for biting surface 300 in inspection 2, filling birth for fourth side surface 308 in inspection 2, and dripping 404 from fourth side surface 308 in inspection 4.

15 The only change in the tooth 16 is the birth of the filling on the 406 chewing surface at 300 inspection 3.

Changes in tooth 15 are: birth of filler 408 on chewing surface 300 on check 3, dripping of filler 410 on chewing surface 300 on check 5.

; The only change in the tooth 14 is the birth of the filling 412 on the second side '·' · 'surface 304 in Inspection 3.

'. '·: There are no changes for teeth 13 and 12.

Changes in tooth 11 are: filling 414 on first side surface 302 in inspection 0, and filling 416 on first side surface 25 on surface 302 in inspection 1.

The system of Figure 1 also comprises computer-implemented. ,: The analysis system 120, based on the effects, forms the analysis chapter ···. ' burn resistance. The assay system 120 preferably utilizes winding analysis to analyze the strength of the piece. In scientific trial type-30 studies, dental health and / or fillers in the mouth are purged; The time of onset is monitored digitally during the Survival period, which is the most commonly used scientific statistical method to estimate the significance of observed survival, IT · time, by most complex computer programs. In the past, for drawing Survival curves, the data had to be modified in order to allow further analysis of the data using the statistical software used (eg SAS or SPSS). 8 109243 requires the above programming skills and adequate command of the statistical software used. See M.K.B., which is incorporated herein by reference.

Palmar: Survival Analysis - A Practical Approach, Chichester Wiley cop. 1995.

In the system of Figure 1, the 5 patient records collected from routine dental care, such as fillers in the "de-Cursus" section of the treatment document, are included in Survival monitoring. Various fillers on different teeth and tooth surfaces are monitored for Survival, whereby the placement of the filler in the mouth is recorded from the decursus markings to the accuracy of the day, and the filler interval, this interval, Survival time, automatically becomes 10 for each filler, dentist, and .

Connected to nationwide and continental networks, it provides real-time information on the practical persistence of different fillers, as well as changes in the slope of Survival curves for thousands of blind users. All of these follow-up can be performed at different levels of care (basic, specialist, and advanced specialist care) so that individual patient records are by no means recognizable.

The simplified status markings illustrated in Figure 4 may be pictorial; as described in Section 5, customize for dental treatment. The marking 520 describes the "birth" of the filling, i.e. the first patching, marking; *, the tag 522 "event 1" or padding change, the tag 524 '' event j 2 "or padding, and the tag 526" censorship "or" stop tracking. "It is interesting in this modification that for example, the filling on the first side surface of the tooth 17 was created in Inspection 0 and replaced with a new infill in Inspection 2. Thus, the first infill lasted 500 times in the timeline. • another padding was found in check 4. Thus, the second padding lasted for the time period depicted on timeline 502. The second new padding lasted at least the time period depicted on the timeline • 30,504 because at the end of follow-up in check 5 it was: still in place.

Similarly, in Fig. 4, timelines 506, 508, 510, 512, 514, 516 describing the durability of their fillings are also formed for other teeth.

In Figure 6, the fill times for each tooth surface of each tooth are plotted against time-space. It should be noted that the time space is now different from that of Figures 3, 4 and 5. The horizontal axis represents the passage of time, and the control sequence numbers as in Figures 3, 4 and 5. Thus, for example, the filling on the other side surface of the tooth 11 has lasted the longest.

Figures 3, 4, 5 and 6 were only intended to illustrate the processing performed in the system. In practice, of course, the processing is done by numerical calculation and not by drawing graphs, except for the sake of illustration, the graphs are drawn.

The system comprises means 112, 114, 116, 122,124 for collecting from the patient information system 100, 102, 104 the effects on the analysis system 120. FIG. 10 is a 1 patient information system 100, 102, 104 comprising an actual patient information system with databases 110, and means 112 for The data 114 is transmitted by means of communication means 116, such as a fixed or wireless connection 15, to an analysis system 120. The necessary data can also be transferred to a storage medium 114 and stored on a computer memory, e.g. to the location of the analysis system 120, where the data is then read from the storage medium to the analysis system 120.

The data can also be printed on paper and then entered by computer writers; 20 to the analysis system 120. This embodiment can be used, e.g. where paper documents are produced for treatment statistics or treatment insurance claims. There are also other known ways of transmitting information in the context of:; computer system can be used. The patient information system 100 and the analysis system 120 can also be integrated into a single-site integrated system, whereby data transfer is performed from one system to another, preferably utilizing the capabilities of the systems to provide the most efficient data transfer possible. · Using various communication ports provided by the computer or the programming languages used: '' '.

In one embodiment, the analysis system 120 then comprises: the communication means 122 receiving the transferred intermediate file 114. The intermediate file 114 may be edited by the means 124 before being stored in the intermediate file 126. Thus, the contents 126 of the various patient information systems 100, 102, 104 are compiled. The 35 data contained in the intermediate file 126 are then subjected to the actual Survival analysis by the analysis software 128.

109243 10

Thus, the patient information system 100, 102, 104 comprises means 112 for generating a status tag intermediate file 114, which is transmitted over the communication link or by other suitable means to the analysis system.

The means 112 and the means 124 are, in a sense, alternate with each other.

The means 112 may modify the structure of the intermediate file 114 before transferring it over the communication link to the analysis system 120. This reduces the need for the required data transfer capacity. On the other hand, the means 124 can only be modified in the analysis system 120. This reduces the need to make changes to each patient information system 100, 102, 104, i.e., receives the information as received from each patient information system and then edits it to the appropriate common data structure format. Of course, a solution is also possible in which the functionality of the devices 112 and 124 is decentralized to both the patient information system 100, 102, 104 and the analysis system 120.

The operating principle is that any dental status or procedure in which the teeth are examined and treated at specific intervals is compiled into an intermediate file 126. This results in a digital file 126 of all statuses in digital form which contains at least the following information: monitoring. . time, tooth condition, '' birth '', events, censorship, tooth number,; 20 tooth surface, patch material. Table 2 describes this structure of the intermediate file '·'. · *. The intermediate file 126 may also contain other information, such as the patient's personal identification code and gender, the municipality of the clinic location, in the form of * ··, the user of the person performing the operation (that is, the doctor or dentist). In one preferred embodiment, the intermediate file 126 does not contain the personal identification data of 25 patients for privacy reasons.

It should be noted that while patient information systems 100, 102, 104. . Even if they use different codes and storage formats, for example, from different fillers, the codes can be aligned so that intermediate file 126 has *: * only one type of code for fillers, which makes it easier to analyze the material using survival analysis.

Figure 2 illustrates the system interface. The intermediate file 126 can be formed by the analysis system 120 using Survival analysis. at least one of the following data: tooth space shelf life, tooth space shelf life by material, tooth space shelf life by ham-35 masseurs, and tooth space shelf life by geographical area. The example describes the persistence of a patch. On screen 200, the user can enter 109243 11 different parameters in display selection section 204. In selection section 204, area 206 is selected as municipal code 564, field 208 is age group 19, field 210 is gender selected, field 212 is selected all surfaces, field 214 is selected all 5 are selected as substances and all teeth are selected in field 216. The user then presses button 218, whereupon the desired Survival analysis is performed. The result of the Survival analysis is shown in the graph section 202 of the display 200.

In summary, the analysis system 120 operates as follows: • A) The user selects the type of survival analysis of his choice from the main menu.

15 B) Open a cohort definition form to enter the data required for analysis.

t C) Constructing an SQL query (Structured Query Language) to be performed on the intermediate file 126 based on the user's choice.

: D) Save the search results to a job file.

20 E) Calculate from the work file, by statistical unit, the Survival times and statuses required for Survival analysis.

F) Perform a Survival analysis.

109243 12 G) Draw a survival curve based on the estimates from the analysis.

If necessary, steps C-G are repeated until all desired Survival curves are drawn.

5 The curve in the vertical axis describes the position instability in percent. That is, if the instability is 0%, then all the places are still in place, and if the instability is 100%, all the places are dropped or replaced. The horizontal axis represents time in years. So this is a set of Kaplan-Meier curves, which can easily be interpreted as the 10 goodnesses of the place materials. The matrix YM appears to be best tolerated by its curve 220. The second best matrix is by curve 222 AM. The locator LC is the third most durable by curve 226, and the worst locator is L1 by curve 224. Examination of the curves may also reveal other information, for example, that after just over eleven years, all fillers made from the L1 material have either been dropped or replaced.

Thus, in the system, new materials are tested in nursing, the sustainability of which is researched through Survival analysis. The research activity automatically utilizes all care activities; · · 20 digital tracking information produced by the patient, regardless of the method used to record the information in the context of treatment. Although the example only describes the durability of fillers, it is clear that the system can be used to analyze the durability of any body used for treatment. Innovation: ·· This system means that data collected for health statistical and billing purposes is automatically converted into scientific Survival information without the need to edit the original health files, and without revealing the patient's personal information. when compiling summary data. The well-known mathematical and statistical processing techniques can be implemented as a simple curve generated by the Visual Basic program, * '30 bars, which shows directly the differences between the various materials, however, without statistical significance calculation. It is possible to do this when the intermediate files are processed by the currently commercially available statistical computer! programs.

As already stated above, the patient information system 100, 102, 104 and the analysis system 120 are implemented on a computer, in particular software running on a computer processor, for example, each required function 109243 13 is implemented as a separate program module. The actual patient information system 110, the means 112, 124, the analysis software 128 are thus implemented as program modules. The database and intermediate files 114, 126 of the actual patient information system 110 are implemented in ways known to those skilled in the art, for example as file structures or databases. The communication means 116 and 122 are implemented, for example, by a combination of software and hardware such as a modem or a network card. The computer program may be designed to run on a normal general purpose personal computer, a laptop computer, a computer network server or other prior art computer. System components can also be implemented as a hardware solution, such as one or more Application Specific Integrated Circuits (ASICs), or as operating logic built from discrete components. In selecting the means of implementation, one skilled in the art will consider, for example, the processing power required and the cost of manufacture. Various hybrid implementations of software and hardware are also possible.

Referring now to Figure 7, a method for analyzing the durability of a patient placed for therapeutic purposes will now be described. Execution of the method begins at block 700.

. 1i 20 In block 702, the body is placed in the set I | for therapeutic purposes v .: Patients.

.'J In block 704, to control treatment outcome, the effect of the paragraph in different patients is examined repeatedly. Then, in block 706, the character; ·> · Affect the computerized patient information system 100, 102, 104 25 for treatment tracking and billing.

The operations of the blocks 702, 704, 706 can be repeated during the tracking time. . in principle, unlimited. The repetition is illustrated by arrow 708, according to which block 708 goes to block 702. Operations 702, 704, 706 can be performed geographically at different locations, for example, in different locations, 11 to 30 different countries, and even on different continents.

'': Then, in block 712, the effects on the computer-implemented analysis system 120 are collected from at least one patient information system 100, 102, | 104. In principle, this procedure can be performed at any time, regardless of procedures 702, 704, 706. The only condition is that procedures 702, 35 704, 706 have been performed to a sufficient number of patients for the result of the analysis to be reliable. The dashed arrow 710 illustrates the temporal relationship between blocks 706 and 712. The arrow 714 illustrates the repetition of the operation of block 712.

Finally, in block 718, an analysis of the durability of the piece is made based on the effects in the analysis system 120. This operation 5 can be performed after block 712 has been performed, this dependency is illustrated by the dashed arrow from block 712 to block 718. The execution of the method is terminated in block 720.

The method may be modified according to the appended dependent claims. Since their contents have been described above in connection with system 10, the description will not be repeated here.

Although the invention has been described above with reference to the example of the accompanying drawings, it is clear that the invention is not limited thereto, but can be modified in many ways within the scope of the inventive idea set forth in the appended claims. 1 ·
