Even though the server responded OK, it is possible the submission was not processed. This brilliant guide to medical informatics is an easy to read overview of the basic concepts of information and communication technologies in healthcare. Not only does the book cover the complexities and implications of the increasing use of information technology in healthcare, but it also explores the basic principles of informatics that govern clinical decisions and behaviour.
As before, the emphasis throughout the book is clinically relevant. New to this restructured and updated edition is a section on searching for, structuring and using information, new material on evidence-based medicine and discussion of the internet and patient use.

Textbooks, journal articles, clinical guidelines, image libraries, and material designed for patient education are increasingly becoming available electronically. Discussing individual electronic health records and relevant reference material with patients is preferable to discussing general information about their problem. If Ms Patel and her surgeon are discussing whether she may need a lumpectomy or a simple mastectomy, then the ability to view a relevant image and brief text making the comparison will probably be more effective than a comprehensive treatise on all the possible procedures.
In lumpectomy, the surgeon removes the In simple mastectomy, the surgeon breast cancer and some normal tissue removes the whole breast. Some lymph around it.

During the discussion of a potentially serious problem like Comparison of lumpectomy and mastectomy—simple diagrams with brief breast cancer, the issue of prognosis will probably arise.
Until text can be effective in consultations. In a few cases such as head injury or seriously ill patients in the intensive care unit accurate, well calibrated clinical prediction rules like the Glasgow coma scale are available. Problems with information retrieval during consultations Although much information is at hand, it is often difficult to find the most clinically relevant items.
Studies measuring the use of information resources during consultations showed individual clinicians accessed the resources only a few times a month.
To encourage clinicians to make more use of these information resources, other approaches to information retrieval during the encounter are being studied.

Dr McKay also says that Ms Smith should be referred to a renal physician, Dr Jones, and a community dietitian for further assessment. Ms Smith agrees, and Dr McKay telephones the hospital to discuss these matters during the consultation. Dr McKay then uses an electronic referral form on the hospital outpatient booking website to provide the information required by colleagues at the local hospital.

J Am Med Inform Assoc ; Summary The strengths of human thought processes may be complemented by the strengths of electronic tools. The initial costs of developing and implementing new information systems may be high, but the costs thereafter can be lower than the non-electronic source that is being replaced. Lower costs and better outcomes mean that informatics tools are moving from an era of hype to one in which real benefits are seen.

Clinical management system support information Arranging follow-up support design systems At the end of a hospital outpatient visit a decision is made about whether hospital, a GP, or shared care is most appropriate for the patient.
In reality, neither are doing so. To avoid such errors, healthcare systems have developed ways of integrating multiple service providers Functional and clinical outcomes and proactive measures see chronic care model opposite. Overview of the chronic care model. Adapted from Wagner EH. Often, patients are If follow-up at hospital is needed then asked to book their next appointment as they leave the clinic.
GP follow-up If the hospital team decide that the patient requires medical supervision, but no other hospital resources, the primary care team may be asked to resume sole responsibility for care.
This is the simplest option for hospitals because it only needs a discharge letter to be sent. Most practices in the United Kingdom and other industrialised countries have the technology and systems to support a call-recall system for screening. Although this can be extended to support GP follow-up of chronic diseases, few practices are able to harness such systems to long term clinical care. This will probably change in countries like the United Kingdom, where achieving targets is increasingly important.
Shared care Although shared care seems the most complex of the three follow-up options, done properly, it may be the best for the patient.
An integrated service takes responsibility for all patients with the problem it is set up to deal with. Specialists ensure that healthcare services are configured to respond effectively to Sharing information across health systems. Clinical data for example, data patients with problems, and to support clinicians working in the on prescribing or blood pressure in one part of the health system that have community.
Good, but often asynchronous, communication between colleagues with complementary skills is vital. In some systems, records may be seen by clinicians irrespective of where they are working.
No matter consultation, written material about their problem, or what arrangement is made for follow-up by the health website addresses that provide further information.
Data, often from patient records, are then collected to confirm whether standards are being met, or if there are any defects to treasure. Failure to hit the target for example, to offer annual blood pressure and renal function tests to Ms Smith , is an opportunity to improve the service.

For example, medical doctors would be reviewing the laboratory test and radiology test results, the physical examination, the routine ward measurements, the feedback from the nursing staff as well as the patient history, in order to combine this information with their cognitive skills, knowledge and experience, to assess the health condition of a patient and conclude a diagnosis and an appropriate treatment plan.
Prior to the hospital admission: data collected during the triage phase. During the triage phase, health professionals determine the priority of patients' treatments based on the severity of their condition.
It result in determining the order and priority of emergency treatment, transport and destination for the patient. These data have been ordered by the medical doctor in charge and Laboratory Information System LIS receives this order, and as soon as the samples arrive at the hospital laboratories, there is a variable required time for each test to be processed.
As soon as this is done, the results are uploaded via the LIS and the Electronic Medical Record would then be updated with the laboratory test result. The physician will then be notified and timely review the results, in order to make informed decisions.
Radiology department: medical images, segmentation and handling of images using DICOM systems, assessments from radiologists. Pharmacy: including Rx, re -stocking and ordering Patient assessment: medical diagnosis, ordering of laboratory examinations, decisions of the appropriate medication.
During a patient hospitalization, there is typically only one primary patient diagnosis. This is the diagnosis which, in the majority of the cases, is considered to be the main reason that led to the decision for a patient admission to the hospital.
Secondary diagnoses, are either pre-existing diseases usually chronic conditions or were diagnosed during the hospital stay.
Tracking down medication: dosage, method of administration e. Nurses will be responsible for the management of the medication administering to the patient, according to the physician guidelines. Discharge data: discharge destination, discharge method, discharge outcome s. Data produced by the patient: patient experiences surveys have recently become the norm and it is widely recognized that the patient feedback does matter.

Hospital budgeting is not a trivial process by any means and requires multidisciplinary work of people who know the healthcare market, understand health economics and reimbursement challenges, and health professionals who can foresee the healthcare delivery challenges.
A Diagnosis-Related Group DRG is a statistical system of classifying any inpatient stay, into groups for the purposes of payment. The DRG classification system divides possible diagnoses into more than 20 major body systems and subdivides them into almost groups for the purpose of Medicare reimbursement3.
Hospital Quality of Care Evaluation and Quality improvement data: we will devote a separate chapter for this very important topic, to discuss the strategic goals of the healthcare system, discuss the dimensions of the quality of care and patient safety and strategies for the healthcare system to assess the quality of health care delivery. The HCAHPS results posted on Hospital Compare allow consumers to make fair and objective comparisons between hospitals and with state and national averages on important measures of patients' perspectives of care.
The survey asks a random sample of recently discharged adult patients to give feedback about topics like how well nurses and doctors communicated, how responsive hospital staff were to patient needs, how well the hospital managed patients' pain, and the cleanliness and quietness of the hospital environment.
Patients are the best sources of information on these topics. Source: Medicare. For the majority of the cases, any data comes from reference data, or in other words data dictionaries, which, as mentioned earlier in this chapter, are predefined lists specifying the acceptable input. This is an enormous list of approximately 68, different codes, following a hierarchical organization.
Each code represents a medical condition. The doctor needs to decide which code would accurately describe the patient condition, and to select the appropriate ICD code for that condition.
There are several levels of depth in ICD and the diagnosis often does not reach the deepest level for a condition. ICD is not the only classification system in use. For the vast majority of in-hospital data, there is existing one or more classification systems, which standardizes the data entry and retrieval process. Chapter 7 will cover some of the most important classification systems and standards which are used by the major health care providers in the United States.
Numeric data, such as physiological measurements and laboratory test results are captured and entered into the Electronic Medical Records without any modifications and without any use of reference data. In this section, we will discuss health care data of various data types. Numeric data allow a much more efficient data manipulation and therefore a more effective use of data to produce aggregated information and make other simple of more advanced calculations. Numbers often come from clinical measurements in hospitals, like, for instance, vital sign measurements.
These data have to be entered into the system indicating the exact value of the measurement. Acceptable decimal precision varies, according to the nature of the data and the precision of the measurement device, if used.
Many numeric data in everyday practice are derived data. For example, the 24h fluid intake and fluid output are used to calculate the fluid balance of a patient. Laboratory examination results are very often in numeric format. These are often accompanied by the reference normal values. An Electronic Medical Record, nowadays, is expected to have those normal values integrated.
Therefore, during data entry, when a laboratory test result for a patient is off bounds, this should be indicated with the use of a different color and potentially a notification should be generated.
It should be mentioned, though, that very often, there are different normal value bounds for different age groups and patient gender. This should be taken into account in such implementations, which should automatically recognize the patient demographics and present personalized notifications for a patient, which are in accordance with patient attributes such as gender and age group.
Comparison of new examination results with previous results of the current and recent hospital stays is of uttermost importance for health care professionals, so that they can better assess the disease progression, re-evaluate the therapeutic plan and make a more informed assessment of the patient prognosis. It is therefore, important, for comparisons to be made, and the result of these comparisons should be notified to the physician. She was therefore admitted as an emergency hypertension case.
As soon as the patient was admitted, she received hydralazine IV, and was been monitored with the use of a bedside monitor. Nurses have been checking the monitor every hour and updating the patient record with the blood pressure value.
Examples of laboratory tests that produce numeric data are numerous. Numeric data are also often accessed and utilized by professionals indirectly involved in patient care. An example can the number of vacant beds in a hospital department. Some numeric data is used by the hospital quality department or healthcare policy makers.
Usually these data are in the form of indicators: for example, the mortality and morbidity during the month June , and the number of cases of infectious diseases divided by the number of patients admitted during a set time period. Boolean Data: Boolean data types in health care can only have two values usually denoted true and false , which represent the truth values of logic and Boolean algebra. Did the patient undergo a surgical operation in the past? Does the patient receive any drugs?
Admission of Patients: Did the patient arrive at the hospital with an ambulance? Was the admission an emergency one? Non-directly related with the patient care: Does the patient have an insurance plan? Alphanumeric Data: also frequently generated during the healthcare process. Data in healthcare can be images: the medical imaging methods below produce data in the form of images. Medical images are generated by medical imaging devices.
Images are usually compressed with simple lossless and near-lossless methods and usually require large storage space. It includes a file format definition and a network communications protocol. There are other obvious data in the form of images in some healthcare organizations, like a patient photo which is uploaded into the Electronic Medical Record.
The trend is to reduce the use of free text data as much as possible: Information in the form of codes is assigned to each separate concept with significant benefits related to the data quality. The advantages of using classification systems are also significant to researchers, since they can save significant amount of time for data preparation, trying to manually merge descriptions of conditions with different wording different syntactic but same meaning same semantic.
Chapter 7 outlines the importance of classification systems and discusses a selection of some critical standards. In other words, the table will provide to you an idea about the location where new data is being generated in a hospital.
