Description

Documentation system for doctor and hospital

The present invention is generally related to a system for documentation, analysis, reporting and quality assurance. More specifically, the present invention is related to an intelligent multimedia system for documentation, analysis, reporting and quality assurance for use in health- and hospital environments. The system uses time connected sequences of several types of entry data.

The requirements for documentation in hospital environments are constant increasing at the same time as the amount of data is increasing drastically, and nevertheless data of the type multimedia data (e.g. video). There exists different systems for storage of documents and electronic procedures fore use in hospitals and equivalent environments. These existing systems are often based on standard procedures having little flexibility in relation to the large variations among patients and their case history, treatment needs etc. Some of these existing systems are addressed towards telemedicine, and deals only with pure storage of data and are arranged for medical treatment where the patient and medical personnel are not situated on the same geographical location. Today's systems are expensive and little flexible in relation to adjustment to the user (doctors) needs and interaction with other systems. The existing systems are often connected to a single instrument and can not handle several different entry data or give the possibility to analyze and simple and quickly retrieve stored information. They are not made with a view on efficient reporting and quality assurance, and are little flexible in the terms of complex connection of all the different systems, sensors, medical equipment etc. to be found in hospitals.

The patent publication WO 2006/119396 A2 describes a system for delivery of medical services where medical personnel and patient are not located at the same geographical place. During a patient examination, the medical personnel can see the electronic journal of the patient and input new medical information in the journal being stored in a database. These patient journals are also connected to order of laboratory examinations and the results from these, pharmacies and order of medicines, order of x-ray examinations etc. A database connected to a surveillance system for medical decisions, where the database contains registers for medical decisions, and used as a template for procedures during medical examinations. The patent publication EP 1262902 Al describes an electronic procedure which step by step assists a dentist in performing odontological examinations. Different odontological standard procedures are stored on a central server. The individual dentist offices download these procedures when needed, and the dentist can follow the procedure for the examination on a screen.

The patent publication US 2006/0137699 Al describes a system for delivery of data with destination information to a medical device.

There exist some solutions for analysing i.a. text, video and audio. Qualis Research Associates in the US has a product called Etnograph, which is a data tool for systematising text based qualitative data. The Etnograph has a search function for text data which labels the data with code words and performs further analysis which can be retrieved for later use. The data tool has application within health, library, market analysis etc.

The German company Mangold GmbH has developed a software (Interact) being a tool used in interaction analysis of behaviour between parents and children, married couples and group behaviour. Behaviour between for example parents and children is filmed by means of for instance a video camera, and the video is stored digitally and analysed by means of Interact. Interact makes it possible to change between stored events, and can play of different video fragments several times making it possible to go into detail in the video. External data such as for example physiological information can be included in the analysis process. Interact offers different possibilities for visualisation and analysis of video and other sensor data, and gives i.a. possibility to choose fixed-term events and to compare different events. The software can also be used for analysis of sound, video and other types of sensor data.

Nihon Koheden is leading in Japan on production, development and distribution of medical electronic equipment for use in i.e. sleep analysis, neurology and cardiology. This company has developed a system called Neurofax EEG which combines EEG (Elektroencefalogram, neurophysiological measurement and registration of the brain's electrical activity) and video. In this system, it is possible to define events, for i.e., epilepsy studies, and to track comments, and to quickly jump between different events.

In many health companies, the transition from a paper based to an electronic system is relatively new. There are still some hospitals that have not started to use electronic aids within documentation in any great extent. Even though some electronic aids exist on hospitals, there are still many hospitals having a paper based journal system. This makes the documentation process on hospitals little effective, and at needs for post analysis of for example an operation, it is often difficult and time consuming to find the correct documentation. This ineffective system is nor a very good basis for quality assurance. The existing electronic systems are isolated systems that do not communicate with each other at all, or in a limited and not sufficient way. Doctors use video equipment and images, but there exists no satisfactory good solutions for handling of multimedia data, and quick editing and retrieval of video sequences and specific events.

It is therefore a need for a system which simplifies and increases the efficiency of the documentation, analysis and reporting of operations and examinations, a system to be used in education and research within the hospital and health sector, and that provides quality assurance. It is a need for a system having "intelligent" characteristics so that the documentation takes place based on previously stored time connected documentation, information, procedures and events about a patient based on several types of entry data. There will be a need for a system having direct connection to necessary information about patients, and that at the same time stores video and other sensor data together with operator input (events, comments etc). It is also a need for a system handling large amounts of multimedia data, where sensor data and operator input is searchable information so that one easily can perform analysis and make adjusted reports to those needing this.

Control of quality and safety in patient treatments are very important, and it is therefore a need for one system having responsibility for and taking care of the documentation of data to secure quality and safety in patient treatments, instead of the traditional paper based documentation. Especially, this will be valid for documentation and follow-up of deviations, for example at an incorrect treatment or when unexpected complications arise during an operation. The present invention secures an efficient and correct treatment of patients in all phases of a treatment, and solves the problems more and more hospitals have in relation to increased demands for retrievable documentation, quality assurance and efficiency improvement. The present invention is a costumer adapted multimedia system for documentation, analysis, reporting and quality assurance which simplifies, increases the efficiency and increases the quality of the hospital work. The system has access to previously stored information about patients and procedures, and chooses a setup for data collection themselves based on this information or according to input from medical personnel. The system registers and stores information from sensors (camera, microphone, ultrasound device, pulse sensor etc) and medical personnel while an examination or operation is proceeding. The system chooses setup for reporting (result documentation) on the basis of input from medical personnel and distributes reports to those recipients following from the chosen setup, including update of information about the patient. With this system, necessary documentation will be prepared so that next segment in the treatment can start without loss of time. The system will also secure sufficient documentation in the case of complications (for example incorrect treatment) during an operation. The present invention makes it possible to establish a library of "interesting cases" which can be used in teaching contexts or as help in difficult situations. On the basis of this library, the system gives the possibility to establish a "best practice" for various cases. The present invention is a useful tool for planning, documentation and quality assurance of important hospital functions. Such a system with "intelligent" characteristics gives the possibility to efficiency improvement and improvement of quality in relation to existing hospital documentation systems.

The above mentioned needs and lacks are covered by the following description and the enclosed patent claim 1.

The invention will now be described with reference to the enclosed figures.

Fig. 1 is a sketch showing use of the system through the whole process for treatment of a patient.

Fig. 2 illustrates the system architecture. Fig. 1 shows how the system is used throughout the whole process at treatment of a patient. The upper part of Fig. 1 describes the steps consultation 1, examinations and sampling 2, diagnosis 3 and selection of treatment 4. The lower part of Fig. 1 describes the following steps comprising operation procedure 5, operation 6, analysis, evaluation and reporting 7 and training 8. All these steps can exchange data by means of for example being connected to a network and the server(s) 9. The treatment process of a patient begins with that the patients comes to a consultation 1 to a doctor. In the room where the consultation 1 takes place, computers are situated, for example a laptop, a device for recording sound (for example a microphone connected to PC in relation to speech recognition software) and various examination instruments such as for example ultrasound and MR. The doctor uses the computer to collect previously stored information about the patient and to enter in new information. Previously stored information can for example be name, date of birth, weight, height, previous case history. This information is collected by the doctor from an electronic patient journal and/or data from the server(s) 9. During the consultation 1, the doctor performs simple examinations of a patient who for example has pain in his left knee. The doctor registers new or changed information about the patient, and his/hers evaluation of the illness. This information is stored on the server(s) 9. On the basis of the consultation 1, it can be necessary to perform more thorough examination and sampling 2, such as for example MR-scanning, ultrasound, blood test etc. All instruments being used in the examination and the sampling 2, such as for example MR-device and x-ray device, are connected to the computer so that the result from the examinations 2 is visible on the computer screen so that the doctor can analyse it. The doctor or the medical personnel performing these examinations and sampling 2 can input comments, both by speech and written, in relation to MR and x-ray image. These comments are stored together with the images on the server(s) 9. During an examination and sampling 2, for example an x-ray examination, several x-ray images will off course be taken, and some of these shows if it is a fracture in the knuckles or of it is for example a meniscus injury. These relevant x-ray images will be connected to a report to the electronic patient journal, while all the images are stored on the server 9.

Then, a diagnosis 3 is made on the basis of the examination and sampling 2, possibly in combination with the previous relevant case history of the patient. All these data being relevant for the diagnostics 3 is fetched via the electronic journal of the patient. The electronic journal contains only one summary of the most important information related to the patient. If the doctor needs more detailed information about the patient in relation to the diagnostics 3 it is possible to fetch all information stored related to the patient from the server(s) 9. The doctor making the diagnostics 3 will usually explain the results of the examination and the sampling 2 and give a verbal interpretation of them to the patient. This verbal interpretation will be useful and applicable later in the patient treatment, and it is therefore necessary to store this verbal interpretation. A microphone is connected to the computer such that the verbal interpretation can be stored on the server(s) 9. The system according to the present invention stores the verbal interpretations of the doctor in connection to for example x-ray and ultrasound image of the patients knee such that there is a connection between image and sound. The doctor can also store written comments in addition to the oral. This information being the result of a diagnostics 3 is stored together with indexes, such that it will be simple to retrieve for example MR images showing meniscus injuries. Sound will also be stored together with indexes so that it is searchable.

Based on the diagnosis 3 of the patient, for example meniscus injury in the left knee, further treatment 4 is selected. If it is not possible to treat the meniscus injury by means of physical therapy and exercise, it will then be natural to operate the patient's knee.

Based on diagnosis and previously stored multimedia data about the patient's knee injury, an operation procedure 5 will be selected. The present invention has a procedure unit containing standard procedures for different operations, and in this example a procedure for meniscus operation will be selected. These procedures are individually adjusted by the doctor to the individual patient. Multimedia data (images, comments, sensor data etc) from previous examinations 2 is connected to the selected operation procedure 5 and one decides which selection possibilities that shall be used in the procedure 5. An example of selection in the operation procedure 5 can be to operate the meniscus in left or right knee. In addition, for example the patient's weight is used to decide the amount of drugs/anaesthesia that shall be used. The operation procedure 5 is designed such that it contains a description of what shall be performed before the operation, how the operation shall be performed step by step, and what shall be performed after the operation. The different steps have connections to previously stored information about the patient being necessary in the relevant step. The stored information is fetched from the server(s) 9. The operation procedure 5 also gives a message to the medical personnel if something must be documented besides the standard.

For example, if the painful knee of the patients is due to a meniscus injury and the necessary treatment is an operation, it will be obvious to use an operation procedure 5 for arthroscopy. The procedure 5 for this operation will be shown on a screen in the surgery. Both a keyboard and foot pedals can be connected to the computer and can be used by the medical personnel to communicate with the system during an operation 6. This procedure 5 shows step by step what shall be performed by the doctor and other medical personnel, both relating to the medical being performed, which equipment being necessary in addition to what shall be documented etc. In the surgery, at least one camera is installed continuously filming the whole operation 6. It can be one or more cameras filming from different angles. In addition, a microphone is connected which records all sound/speech during the operation 6. The first step in the operation procedure 5 can for example be to find all the necessary equipment, for example scalpel, pincette, arthroscopy devices etc. The responsible person for the equipment ticks of a check list connected to the procedure 5 on the screen as he/her finds equipment. The consumption of equipment is reported to the hospital storage of medical equipment such that the stock of goods can be updated according to how much equipment is taken out in relation to for example the meniscus operation. When all equipment is found, and all the points in the check list are ticked, the responsible person presses a button on the keyboard or possibly a foot pedal to indicate that this step in the procedure 5 is performed. The next step in the operation procedure 5 can be to find different medicines needed during the operation 6. for example anaesthetic, pain-killers, antibiotics etc. The responsible person for medication uses information about for example the patient's weight, length etc to calculate the amount of medicine. The medicine responsible registers the amount of medicine to be used in the operation 6 such that it is stored on the server(s) 9, and is information fetched when needed in the future. If situations arises during the operation 6 that leads to that the patient must have additional medicine, the medicine responsible also registers this in the system. The amount and type of medicine being used in the operation 6 is reported to the medicine storage such that the stock of goods for medicines is always updated. When the medicine step in the procedure 5 is performed, a button on the keyboard or a foot pedal is pushed to indicate that this step is finished. The operation procedure 5 keeps track of how far the doctor and the medical personnel have reached in the procedure 5. The procedure 5 contains steps to be performed throughout the whole operation 6 of the patient from start to end. The doctor or the medical personnel goes from step to step by filling out a check list, pushing a button on a keyboard, foot pedal or similar.

The structure and data flow in the system makes it simple for the users to communicate with the system. During the preparatory steps of the operation procedure 5, i.e. before the operation 6 starts, the doctor and the medical personnel performing the preparations will be able to use a keyboard to communicate with the documentation system. On the other hand, during the operation 6, it will not be favourable for a doctor to use a keyboard to communicate with the documentation system. During the operation 6 it will probably be more favourable for the doctor to use a foot pedal to indicate that a step in the operation procedure 5 is finished. Another alternative for communication with the documentation system is speech recognition. A microphone is connected to the computer in the surgery, and the computer contains software for speech recognition. The doctor and the medical personnel then gives oral message to the documentation system to for example proceed to the next step in the operation procedure 5. The microphone is also used by the doctor and the medical personnel to store oral comments connected to the different steps in the procedure 5, and also other storage of information. It can be different persons being responsible for the different steps in the operation procedure 5. Every step involves documentation of what is executed, and assures that sufficient documentation will be available for the next user at any time in the procedure 5. Thereby, unnecessary waiting or multiple jobholding can be avoided.

The operation procedure 5 states clearly if something should be documented beyond the continuous video and sound recording. An example of that can be that the lying position of the patient is documented with an image before the patient is made ready for operation. In addition to video and sound recording, it will be continuous surveillance and logging of physiological variables, for example the body temperature of the patient and blood pressure. If these parameters exceeds or goes below the normal values, for example if the body temperature of the patients sinks, the system will give information about this, and also give the message that this must be documented. During an operation 6 unexpected situations can arise which is not automatically logged and monitored by the system. In such cases, the medical personnel must manually activate extra documentation, for example adjust the angle of a camera towards a desired position. As previously mentioned, the system stores video, sound and other sensor data (for example pulse, blood pressure, EKG). The system stores these multimedia data together with a categorisation of what is observed, i.e. event categories. Speech recognition is used for indexing (tagging) of video to connect video to an event categorisation. The use of "tagging" is a known technique for a person skilled in the art. This makes it possible to search in the multimedia data by using keywords specifying categories and attributes. Sound is also indexed with searchable keywords, such that it is also possible to search in sound in the same way as video. A video clip and/or sound clip matching the search criteria is fetched when searching. An example of such a search can be to search for video clips dealing with knee operations or to search for sequences in sound files where the word meniscus is mentioned. This categorisation and storage of multimedia data takes place in real time. This makes it easy to find a specific time scheduled event at a later opportunity. Definitions of categories and attributes that can be used by the system as bookmarks will be important for the efficiency of the system. An example of a category can be knee operation, and attributes can be left knee, meniscus, athlete. By means of this categorisation, it will be simple to perform detailed search, for example to find an example of a knee operation of an athlete having a meniscus injury in the left knee.

After the operation 6 is finished, analysis, evaluation and reporting 7 is performed. AU multimedia data stored during the operation 6 will be available on the server(s) 9 for use when analysing, evaluating and reporting. As previously mentioned, storage of multimedia data is performed in real time, but some data are stored and connected to the video taken under an operation 6 in the phase of analysis, evaluation and reporting 7.

During an operation 6, the medical personnel is very often stressed such that they do not have time to input detailed information and comments on the way. At the analysis of the operation 6, the medical personnel will often input detailed information about the operation 6 connected to time scheduled sequences in the video. Reports 7 are formed after all operations 6, giving a summary of the operation 6. The system handles reporting 7 (result documentation) automatically. On the basis of input from medical personnel, the system selects the correct setup for reporting 7, and generates relevant reports after for example a meniscus operation. The reports are made on the basis of the operation procedure 5 and connected to stored multimedia data from the operation 6. The reports are customised based on who the recipient is, and the recipient of the report gets only access to the information relevant for them. The system distributes the reports to recipients as a result of a selected setup. There will be different recipients of reports, for example the patient's family doctor and the doctor who performed the operation, the cancer register receives reports on cancer operations, the storage and the purchasing department gets reports on how much and what type of equipment that is used during an operation 6 etc. A report can also be sent to the patient's regular pharmacy such that the pharmacy can get a message of which medicines the patient shall have after the operation. Then, this medicine will be ready and packaged when the patient arrives at the pharmacy to get it. The reports are preferably distributed in an electronic way, but with a possibility to print the report on paper. The report also includes updates of information about the patient if that is necessary. This reporting 7 and updates of patient information leads to that necessary documentation is prepared such that the next segment in the treatment of the patient can start without large loss of time. A report for updating of the electronic journal will also be made.

If deviations or complications arise during or after an operation, it will be relevant to perform thorough analysis and reporting 7 in the future. With this documentation system, it is simple to find the video and other data from the whole operation 5 that can be studied and analysed to find the source for the complication. It is not necessary to look through the whole video of the operation to find the sequence where for example the artery is cut, but by means of the search function, this sequence is found directly. The system is also useful in cases related to patient compensation, and gives definite evidence of which treatment that was given.

Documentation of actions and information related to a treatment of a patient, for example a treatment of a meniscus injury, will be useful to use regarding training 8. The system will have a large amount of stored multimedia data dealing with patient information, treatments and operations of patients with different illnesses, and on the basis of individual situations. These stored data will be used to establish a library of "'interesting cases" for use in training or as a help in difficult situations. All the different cases will contribute to establish a best practice for different cases. This experience database will be searchable regarding specific events (categories and attributes, as previously mentioned) for use in for example training and quality assurance. The system will also be an efficient tool for sharing experiences and giving good advice to colleagues both in a daily operating situation and in a more educational situation. The system comprises the software making it simple to perform accurate and good analysis and evaluations of a patient treatment.

In addition to documentation of the technical performance in a hospital, medical office etc., the system can also be used to document the flow of patients (logistics). This can be done with time registration and/or tracking of patients. Tracking of patients can for example be performed by means of RFID or bar codes on bracelet worn by the patients.

The system is flexible regarding user adjustment. Different users of the system have different needs when using the system, and therefore the system will have a flexibility that makes it adjustable on the basis of user needs. Most users of the system will have some shared general needs for the system, but at the same time there are needs for individual adjustment. A psychiatry unit will for example need a type of adjustment not necessary for a surgical unit. The system is customised and adjusted to the individual user, i.e. for the individual doctor, unit or department and an integrated solutions for the whole hospital. Where different system is used in different units in hospitals today, the present invention will be an integrated system that is easy to use and has the same design and structure in interface irrespective of the system is used in a gynaecological unit or in a skin unit. This makes the system easy to recognize and the threshold for using the system is lower.

In addition to flexibility, it is important that the system also maintains information security. The system is placed under strict requirements regarding protection of privacy, data security and certification. Patient information is sensitive data, and it is therefore important to have a security level ensuring this. In combination with focus on information security, it is also important that the system easily can be connected to or installed on existing infrastructure (PC^"s, network, etc) in hospitals. By using existing infrastructure the costs to start using the system will be heavily reduced.

Fig. 2 shows a simplified sketch of the systems architecture. The system is build up around one or more servers 9 performing storage of multimedia data and communicates with a number of user units 10, 11 , 12, 13. 14. The system units can generally be divided into two categories, units for data collection 10, 11, 12, 14 and units for planning, analysis and reporting 10. The server(s) 9 and a procedure unit 13 not belonging to these categories come in addition. The data collection from consultations 1, examinations and sampling 2, operations 6 and evaluation and analysis 7 basically takes place in the examination room 11, surgery 12 and medical office 10, while the other activities takes place in medical offices 10 by means of software installed on a standard stationary or portable PC. The system's software gives a user interface for presentation, manipulation and analysis of multimedia data. The servers 9 communicate with the units located at places visited by the patients in a treatment course, for example examination room 11 and surgery 12. In addition, the server(s) 9 communicates with the PC's in the medical offices 10, documentation unit/procedure unit 13 comprising different procedures 5. The software on the PC's in the medical offices 10 gives efficient tools for performing analysis, evaluation and reporting 7 of examinations 2 and operations 6, exchange of experiences and consultancy both in a daily operating situation and in a training situation 8.

External expertise 14 can also be connected to the system. This external expertise 14 can for example be an expert doctor who gives expert help during for example an operation 6 where the hospital does not have such available expertise. All communication with the external expertise 14 takes place via telecommunication, equivalent to a standard video conference. The external expertise 14 has access to all information and operation procedure 5 at the same level as the medical personnel situated in the surgery 12. This communication between external expertise 14 and the medical personnel in the surgery 12 will also be stored on the system's server(s) 9 as time continuous sequences in categories based on several types of input data, such as in the surgery 12.

The system treats large amounts of complex multimedia data, and therefore it can be necessary to have an own limited network specially designed to send and handle this type of and amount of data. Such a special network prevents loading existing infrastructure. The amount of data and types of data also involves use of local data storage on servers. The system is designed so that it can be connected to existing networks, for example a normal Ethernet, such that computers or other units located outside the system's own network can also have access to the data on the server(s) 9. Then, external computers or other units must send a request to the system to get approval to access these data. Such an external computer can for example be a computer of the family doctor. The equipment located in an examination room 11 and in the surgery 12 comprises computers (work stations), screens, keyboard, video camera, camera, microphone, foot pedals and other necessary sensors (EEG, ultrasound etc.) for documentation of events. The number and type of sensor is dependent on the type of operation, available equipment etc. Work stations in the medical offices 10 do not treat data amounts being so large and complex, so that these computers can be connected via a normal Ethernet network.

Usually, a doctor is located in an examination room 11 in addition to the patient. The examination room 11 has. as previously mentioned, a computer in addition to a number of different sensors. Examples of sensors located in an examination room 11 are video camera, microphone, ultrasound and MR. In a surgery 12, a collection of medical personnel will be located who shall treat the patient together. This interaction will be useful to observe regarding efficiency improvement, for example by mounting an extra camera so that one can analyse this in the future.

There are different requirements for design, noise level, cleanness etc. for equipment to be located in a hospital environment. The computers located in the medical offices 10 are used for "normal^*' office work, in addition to evaluation and reporting 7 of data. No medical examinations 2 are performed in these medical offices 10, and therefore can the computers in the medical offices 10 be standard computers, such as for instance a laptop. Consultations 1 and examinations 2 of patients that do not require antiseptic equipment are performed in examination rooms 1 1. A consultationl or an examination 2 performed in an examination room 11 can be for example ultrasound. As the examinations 2 perfoπned in the examination room 11 do not require antiseptic equipment, one can here also use standard equipment such as a laptop, microphone, camera etc. However, there are strict requirements for antiseptic equipment in a surgery 12. It is important that all equipment, both medical and other equipment, are antiseptic to avoid i.a. to avoid infections on the patient. It is therefore important that cameras, microphones, pedals. screens etc are protected by or produced of an outer material approved for use in surgeries. An alternative can be to place the system in a separate box fulfilling the requirements to be in antiseptic environments. In addition to the requirement of antiseptic equipment, it is also important that the equipment does not produce to much noise (sound, electromagnetic waves etc) such that it interrupts other medical equipment being used during the operation 6, or that it has a disturbing influence on the medical personnel located in the surgery 12.

Summarized, the present invention relates to a system for documenting, analysing and reporting events and information in relation to the treatment of patients, such that one gets increased quality and efficiency in the treatment. The system is connected to a storage containing previously documented events and information about at least one patient where documented events and information in the storage is categorised and searchable. The system comprises a set of procedures for examination and operation of patients including a set of actions, and tools for fetching and analysing of documented events and information from the storage related to the actions in the procedure. In addition, the system is arranged to categorise and store actions and information registered during and after performance of procedures in the storage.

This leads to a system that contributes to increased efficiency and quality assurance of documentation during treatment of patients. The system communicates with all computers and systems, and medical sensors such that data registered by these is stored, and contains operation procedures adjusted to the individual patient on the basis of previous registered information about the patient. The system gives the users a possibility to search efficient and simple in a large amount of multi media data.

The system is arranged to document events and information taking place during treatment of a patient by multimedia data, where multimedia data can comprise video, sound, image and/or data from medical sensors. This leads to complete information about a patient, possibly also about the medical teamwork, being documented during a treatment process.

The system in the present invention is arranged to generate reports based on documented events and information located in storage, such that the reports are customised for the relevant case and patient, and thereby contains all relevant information about for example the relevant operation that has taken place and relevant information from the previous treatments of the patient. The system is also arranged to distribute the reports to recipients based on the stored events and information. This leads to that all relevant parts participating in the treatment of a patient and has needs for information receives a customised report.

Events and information being stored is categorised based on actions in the procedure. This leads to that the stored data are simple to find and are searchable. It is possible to directly retrieve a relevant action/sequence in for example a video of an operation in stead of looking through the whole movie to find the action/sequence.

The stored events and information belonging to the same action in the procedure are connected and synchronised in time. This causes that if one sees for example a specific video clip from an operation video, this video will be connected to for example a sound file containing the comments from the doctor, measurement of heart beat and/or x-ray images from the relevant body part such that at a future analysis of the operation, the person performing the analysis can have complete information about the desired action.

The system is arranged to document and analyse how the treatment is performed by the medical personnel to thereby improve the efficiency and quality in the treatment, or to be used in relation to demands for compensations for incorrect treatment.
