The chief subject of this assignment is ICD, one of the nomenclatures which influence the cryptography and categorization methods. The execution of coding and categorization is based on the Electronic Health Records ( EHR ) of the inbound and outbound patients. Before traveling straight into chief subject, I need to discourse what is EHR? What are the benefits and disadvantages of EHR? Why controlled Terminology is required for an EHR? What are the different cryptography and categorization systems? What can I anticipate in ICD-11? ``
Electronic Health Records:
Electronic Health Records comes from the epoch of patient records where the chief subject of patient records are to derive medical cognition, for clinical research intents, for farther usage of informations and can easy be a opportunity of doing determination by analyzing the record in an unambiguous mode. Patient Records are many types and they are developed harmonizing to the usage in demand of today 's life [ 2 ] .

Even though the chief intent of all types of medical records are same, like to educate clinicians, support for charge intents, support for clinical research and for epidemiological surveies, It besides has disadvantages depending upon the type of medical record and maintaining mind these disadvantages many new sorts of patient records have now come across [ 3 ] .
In Paper-based medical record, the accessing of patient informations is made easy, but it has some restrictions like, no such patient has merely one wellness attention forces and no wellness attention force has merely one patient because one patient can hold may be more than one doctor and every doctor needs to look into old records like what prescription has been given and what should be the following process to follow, and those records can non be accessed immediately because paper based can remain merely at one topographic point, some may be losing, some can non be understood by other doctors due to their hapless hand-writing. These restrictions are non really utile in order to do a proper determination [ 3 ] . It besides has some advantages like paper based systems are less expensive and recording of informations is non really complex [ 2 ] .
This can be overcome by presenting Computer-Based Patient Records or Electronic Medical Records, where wellness attention suppliers can easy entree patient 's whole wellness certification under individual wellness organisation and most of import is this information can accessed by merely licensed clinicians which can avoid security issues to maintain privateness of patient informations. When compared to informations storage it has disadvantages like, it requires more infinite to enter a patient information in a digital format than Paper based patient record, and besides considered to be more expensive due to the investings in hardware, package and besides the information saved will be lost if whole computing machine system clangs or fails to work [ 2 ] .
Electronic Health Records ( EHR ) which has the capableness to entree patient 's wellness certification under several wellness organisations which is permitted to entree by merely accredited clinicians. The benefits by the EHR to the wellness attention professionals are as follows:
Easy Access to Patient Data: Easy entree to all integrated patient informations taking from simple sort of informations.
The doctors can do an effectual Clinical Decision Support.
Portability: The doctors can entree patient informations anyplace even in ambulatory conditions besides and besides through portable devices.
Clinical Order Entry: EHR can supply new clinical qui vives depending on the informations entered in electronic patient record. It besides has the capableness to demo some literature based on your entry, most of import is qui vives can warn clinicians about the dose of drugs and besides some allergic reactions.
Quick Transfer of Information is possible through several wellness organisations through EHR can be possible [ 2 ] .
EHR besides has some disadvantages:
Understanding of patient informations without proper nomenclature is non possible for EHR.
Collection of Data is impossible in EHR without controlled nomenclature. So, that is ground why medical controlled nomenclature is really of import for the EHR which is discussed in item in the undermentioned process [ 2 ] .
Why do we necessitate Medical Terminology?
Terminology is defined as a standard set of footings to denote a set of constructs [ 4 ] and Clinical Terminology trades about the constructs used in footings of statements in a medical record i.e. significance should be same if we use different constructs to do statements. For Example, This patient has an Endocrine disease and This patient has an Diabetes are said to considered as Terminological because constructs used to do statements denotes same intending [ 5 ] .
Medical Terminology has some standard words or phrases to stand for what has happened to the patient, it does non let doctors to compose something in their ain words. So by stand foring harmonizing to criterions, every doctor whether he belongs to same wellness organisation or different wellness organisation can be able to cognize what had happened to the patient [ 6 ] .
The chief end of Medical Terminology can be enhanced if all the patient has electronic patient records and patient centered information should be entered into the electronic based patient records so that it can be like Re-use of information for clinical and secondary intents and can be shared across different organisations, establishments [ 5 ] .
Positions on Medical Terminology:
Data Abstraction- procedure of abstracting the recorded informations and so delegate a label to the abstracted information ( delegating some specific term which can state whole significance ) from the nomenclature itself [ 7 ] .
Data Representation is delegating codifications to each of the findings done to the patient like research lab findings, physical findings, type of drug administered [ 7 ] .
Encoding of medical cognition is besides of import to portion the cognition or direct the informations to other clinical systems. This encryption is done in such a manner that computing machines can utilize it [ 7 ] .
Benefits of encoding medical cognition: It allows for Alerts in footings of medical specialty prescriptions so that doctor can be cognizant of this state of affairs before he can turn to to the patient [ 10 ] . It can salvage a batch of clip for the doctors or admittance sections without rhenium come ining the patient record after analyzing the patient for multiple times [ 7 ] .
Why Controlled Vocabulary and Coding systems for Terminology are of import?
In past old ages, Imprecision and deficiency of Standardized Controlled Vocabulary has been a major assert for the wellness attention sphere. This is due to the complication between standardisation of medical cognition and nomenclature ( set of constructs ) . The structuring of medical informations in footings of acquisition, entering and storage is of import because it raises the confusion between the nomenclature and significances of the informations. For illustration, one doctor wants to seek for a word 'Diabetes ' , which in fact merely detects patients who are recorded as precisely with 'Diabetes ' as diagnosing but non with patients who are recorded as 'Diabetic ' [ 9 ] and sing another illustration, one doctor declares and records informations as patient has 'shortness of breath ' and another doctor records as 'dyspnea ' , though the patient has same sort of disease but while recovering the patient informations can be displayed as patient with shortness of breath or dyspnoea depending upon the preciseness of the word entered at the retrieval country [ 8 ] . This is the chief job originating in footings of controlled vocabularies.
This job can be solved by the Controlled Terminologies or Clinical cryptography systems which contain the list of standard set of footings which can expose the words denoted under the same set of criterions. For illustration, it can recover all the information of patients enduring from 'Diabetes ' or organize 'Dyspnea ' because these footings are registered under a same set of significances and besides physician can come in or enter the patient informations in different types of degrees. This is the chief advantages of controlled clinical nomenclatures or coding systems [ 7 ] .
Clinical Coding and Classification Systems:
International Classification of Diseases ( ICD ) developed by WHO is the categorization of diseases and other wellness jobs by analyzing the wellness job records and critical records. It has the capableness to sort the diseases in a hierarchical manner so that wellness attention forces can easy recover and place the utile information. It is non merely used for retrieval intent but besides to roll up the population, morbidity and mortality statistics [ 11 ] .
Purpose of ICD:
The chief intent of ICD is the systematic agreement and in a structuring format by comparing and analyzing the causes of mortality and morbidity informations collected from different states. The recording of the information is automatically converted from words to alphanumeric codifications which enable easy storage and retrieval of informations [ 11 ] .
The chief primary purpose to develop ICD to come in mortality statistics based on the decease certifications and subsequently depending on the alterations of different ICD 's taking ICD-1 to now utilizing ICD-10, the group decided to besides include morbidity statistics for diagnostic intents. It besides has the capableness to sort diseases based on the marks, symptoms and unnatural findings where any wellness attention forces can easy derive cognition in an unambiguous mode. It is besides used for charge intents [ 9 ] .
Structure of ICD-10:
Taking from old versions of ICD to late developed version of ICD-10, the construction of ICD follows same construction which was antecedently proposed by William Farr. The construction of ICD-10 is based on Epidemic diseases, general diseases, local diseases, developmental diseases, hurts [ 9 ] .
The construction of the list of categorization of diseases can be shown in the below tabular array [ 9 ] , which is divided into separate columns each column has Chapters, Codes and Description of that diseases [ 9 ] .
It has list of 21 chapters and a set of codifications are assigned to each chapter. Each codification has foremost missive as an Alphabet and each Alphabet is assigned to each chapter but in chapter 2 Neoplasms has D alphabet and besides D alphabet in Diseases of blood.
In general, codifications are assigned as three character codifications which is said to be chief or core categorization of a disease and sub classs of that disease can be denoted as four character classs. To be explain more in item, sing one sort of disease from the tabular array, say Chapter 2 Neoplasm which has codifications from C00-D48 and subcategories which are malignant tumor of Neoplasm are assigned as codifications C00.0-D48.9 three characters followed by an extension with a point. The ICD-10 codifications are denoted in alphameric codifications whereas ICD-9 is denoted merely in numeral codifications merely. There are fresh U codifications in ICD-10 [ 9 ] .
Table: Division of ICD codifications into Chapters [ 9 ] .
Troubles in ICD-10:
There is no possibility of naming the constructs once more under anatomical parts for the constructs which are one time represented in a individual hierarchy. For illustration, if some disease caused by chest malignant neoplastic disease is mentioned in Chapter 2, it can non be mentioned once more in the anatomical parts of diseases covering chapter 6- chapter 16. Even though chest malignant neoplastic disease is related to anatomical part chest, it can non be covered in chapters of anatomical parts. This is the chief drawback of ICD-10 [ 9 ] .
If we want to update a new codification which surely fits under some chief codification for illustration, see chief codification C00 for some disease and we want to update some disease which absolutely suits under chief codification as a sub class codification, it is non at all possible by ICD-10, because updating requires an empty infinite to make full which says that it is non possible to update on behalf of already used codifications [ 9 ] .
The purpose of alterations is to non alter the full construction of the old versions, have to see how to develop an easy manner of accessing medical cognition is possible without any complications, confusions, struggles.
The freshly developed versions includes most ( major nucleus ) of the content, construction every bit same as old versions, merely minor alteration and based on that merely minor alterations can be possible depending on the troubles raised by utilizing the present versions and those troubles are avoided and expected non to see in the hereafter development of versions.
When compared with alterations based on ICD-9 and ICD-10 alterations made are:
Expanded from a individual 3-digit ICD-9 class ( 001 ) to a 3 digit ICD-10 five classs ( A00-A005 ) .
ICD-9 numeral codifications to ICD-10 alpha numeral codifications.
Transfering from one codification to other codification in the categorizations [ 11 ] .
Future Version of ICD ( ICD-11 ) :
What I expect to be changed from ICD-10 to ICD-11:
`` Depending upon the troubles raised in ICD-10, the constructs based on diseases of anatomical parts should be included in anatomical parts constructs because even if person who are non so familiar with some hard footings which denotes the disease can easy be happen the information in anatomical parts and everyone knows the anatomical parts where disease is really in the patient organic structure. So, disease under anatomical parts is of import '' .
`` Categorization of diseases, mortality and morbidity statistics can be done individually under separate chapters for Adults, Neonatal attention, Small kids, Old people so that they can easy distinguish for determination support. This will be a job in footings of dose of drugs and thereby allergic reactions caused by them because dose factor is really less for grownups when compared to little kids '' .
`` Particular sort of categorization can be best thoughts when Neonatal attention is taken into consideration due to most of them are affected by bosom diseases or tumor at a really early age '' .
`` As far EHR is concerned, it is really of import in every wellness organisations so that information can be readily available for the doctors where they can treat in an efficient mode. EHR with Controlled Terminologies and Clinical Coding Classification Systems are besides of import for an easy entree to the medical cognition. More figure of nomenclatures are being developed by recognized organisations like WHO, National Centre for Health Statistics ( NCHS ) where doctors can anticipate an easy manner of accessing medical cognition For Example, function ( associating ) of nomenclature with ICD like SNOMED CT which one of the controlled clinical nomenclature '' .
