Clinical Audit: From 2 Different Sources
A MEDICAL AUDIT carried out by health professionals.
a quality-improvement process that seeks to improve patient care and outcomes through systematic review. Aspects of the structure, processes, and outcomes of care are selected and systematically evaluated against explicit criteria. Where indicated, changes are implemented at an individual, team, or service level and further monitoring is used to confirm improvement in health-care delivery. The assessment, evaluation, and improvement of quality then forms a cycle of activity (audit cycle) that promotes sustained improvement (see diagram).
A distinction may be made between clinical audit, which refers to total care (involving doctors, nurses, paramedical staff, etc.), and medical audit, which refers to medical care specifically performed by doctors, although in practice the two terms are often used interchangeably.

Systematically developed statements which assist clinicians and patients to decide on appropriate treatments for speci?c conditions. The guidelines are attractive to health managers and patients because they are potentially able to reduce variation in clinical practice. This helps to ensure that patients receive the right treatment of an acceptable standard. In England and Wales, the NATIONAL INSTITUTE FOR CLINICAL EXCELLENCE (NICE) is developing national guidelines with advice from health-care professionals and patients to improve clinical e?ectiveness of NHS care. Some doctors have reservations about guidelines because (1) health-care managers might use them primarily to contain costs; (2) in?exibility would discourage clinical innovations; (3) they could encourage litigation by patients. (See also HEALTH CARE COMMISSION; MEDICAL LITIGATION.)... clinical guidelines
An information system that collects, stores and transmits information that is used to support clinical applications (e.g. transmission of laboratory test results, radiology results, prescription drug orders). Electronic medical records are one method by which clinical information systems can be created.... clinical information system
Clinical information, excluding information about treatment and intervention. Clinical information that does not record an intervention is by nature a clinical observation. The observer may be the patient or related person (information about symptoms, family history, occupation or lifestyle) or a health care professional (information about physical signs, measurements, properties observed or diagnoses). While information about the nature of a planned or performed treatment is excluded by the definition, clinical observations may be recorded on the results of a treatment, on progress during the course of a treatment, or on the result of a treatment.... clinical observation
A multidisciplinary set of daily prescriptions and outcome targets for managing the overall care of a specific type of patient, e.g. from pre-admission to post-discharge for patients receiving inpatient care. Clinical pathways are often intended to maintain or improve quality of care and decrease costs for patients in particular diagnosis-related groups.... clinical pathway

A conclusion that an intervention has an effect that is of practical meaning to older persons and health care providers. Even though an intervention is found to have a statistically significant effect, this effect may not be clinically significant. In a trial with a large number of participants, a small difference between treatment and control groups may be statistically significant, but clinically unimportant. In a trial with few participants, an important clinical difference may be observed that does not achieve statistical significance. (A larger trial may be needed to confirm that this is a statistically significant difference).... clinical significance

Initially driven by anxiety about the possibility of medical negligence cases, clinical risk management has evolved into the study of IATROGENIC DISEASE. The ?rst priority of risk managers is to ensure that all therapies in medicine are as safe as possible. Allied to this is a recognition that errors may occur even when error-prevention strategies are in place. Lastly, any accidents that occur are analysed, allowing a broader understanding of their cause. Risk management is generally centred on single adverse events. The threat of litigation is taken as an opportunity to expose unsafe conditions of practice and to put pressure on those with the authority to implement change. These might include senior clinicians, hospital management, the purchasing authorities, and even the Secretary of State for Health. Attention is focused on organisational factors rather than on the individuals involved in a speci?c case.... clinical risk management
A test on human volunteers of the effectiveness and safety of a drug. A trial can also involve systematic comparison of alternative forms of medical or surgical treatment for a particular disorder. Patients involved in clinical trials have to give their consent, and the trials are approved and supervised by an ethics committee.... trial, clinical

(APD, central auditory processing disorder, CAPD) a series of conditions characterized by difficulty in hearing and processing auditory information, especially in poor acoustic environments, despite normal or near-normal ear function. It may be due to genetic factors, maturational delay in the central nervous system, or focal abnormalities of the central nervous system (such as tumours). Treatments include *hearing therapy, *auditory skills training, educational support, use of *assistive listening devices, and training with computerized therapy tools.... auditory processing disorder
(See EVIDENCE-BASED MEDICINE.) Clinical trials aim to evaluate the relative effects of di?erent health-care interventions. They are based on the idea that there must a fair comparison of the alternatives in order to know which is better. Threats to a fair comparison include the play of chance and bias, both of which can cause people to draw the wrong conclusions about how e?ective a treatment or procedure is.
An appreciation of the need to account for chance and bias has led to development of methods where new treatments are compared to either a PLACEBO or to the standard treatment (or both) in a controlled, randomised clinical trial. ‘Controlled’ means that there is a comparison group of patients not receiving the test intervention, and ‘randomised’ implies that patients have been assigned to one or other treatment group entirely by chance and not because of their doctor’s preference. If possible, trials are ‘double-blind’ – that is, neither the patient nor the investigator knows who is receiving which intervention until after the trial is over. All such trials must follow proper ethical standards with the procedure fully explained to patients and their consent obtained.
The conduct, e?ectiveness and duplication of clinical trials have long been subjects of debate. Apart from occasional discoveries of deliberately fraudulent research (see RESEARCH FRAUD AND MISCONDUCT), the structure of some trials are unsatisfactory, statistical analyses are sometimes disputed and major problems have been the – usually unwitting – duplication of trials and non-publication of some trials, restricting access to their ?ndings. Duplication occurs because no formal international mechanism exists to enable research workers to discover whether a clinical trial they are planning is already underway elsewhere or has been completed but never published, perhaps because the results were negative, or no journal was willing to publish it, or the authors or funding authorities decided not to submit it for publication.
In the mid 1980s a proposal was made for an international register of clinical trials. In 1991 the NHS launched a research and development initiative and, liaising with the COCHRANE COLLABORATION, set out to collect systematically data from published randomised clinical trials. In 1994 the NHS set up a Centre for Reviews and Dissemination which, among other responsibilities, maintains a database of research reviews to provide NHS sta? with relevant information.
These e?orts are hampered by availability of information about trials in progress and unpublished completed trials. With a view to improving accessibility of relevant information, the publishers of Current Science, in 1998, launched an online metaregister of ongoing randomised controlled trials.
Subsequently, in October 1999, the editors of the British Medical Journal and the Lancet argued that the case for an international register of all clinical trials prior to their launch was unanswerable. ‘The public’, they said, ‘has the right to know what research is being funded. Researchers and research funders don’t want to waste resources repeating trials already underway.’ Given the widening recognition of the importance to patients and doctors of the practice of EVIDENCE-BASED MEDICINE, the easy availability of information on planned, ongoing and completed clinical trials is vital. The register was ?nally set up in 2005.... clinical trials
a device similar to a *cochlear implant except that the electrode stimulates the auditory parts of the *brainstem rather than the cochlea. It is used to restore hearing of profoundly deaf people who have had damage to both auditory nerves and are hence unsuitable for cochlear implantation. It consists of an electrode that is permanently implanted on the surface of the brainstem. An external device with a microphone and an electronic processing unit pass information to the electrode using radio-frequency waves. The implant is powered by batteries in the external part of the device. It is most commonly used in patients with *neurofibromatosis type II who have had bilateral *vestibular schwannomas.... auditory brainstem implant

(CCGs) self-governing bodies set up by the Health and Social Care Act 2012, following the abolition of *primary care trusts and *strategic health authorities, to commission most NHS services in England. CCGs are formed of all GP practices within a given geographical area, and all GP practices must belong to a clinical commissioning group. All CCGs have their own constitution and governing body, which (in addition to GPs) must include at least one registered nurse and at least one secondary care specialist doctor. There are currently 195 CCGs in England.... clinical commissioning groups

In North America, it is common for hospitals to employ a clinical ethicist or provide a formal clinical ethics consultation service. In the UK, clinical *ethics committees are increasingly common in the NHS.... clinical ethics
(CGI) rating scales commonly used by clinicians to measure symptom severity and treatment response in treatment studies of patients with psychiatric illnesses. Many researchers consider them to be a good tool to measure the clinical utility or relevance of a given treatment. The Clinical Global Impression–Severity scale (CGI-S) is used to rate the severity of the patient’s symptoms relative to the clinician’s past experience with patients who have the same diagnosis. Scores range from 1 (normal) to 7 (extremely ill). The Clinical Global Impression–Improvement scale (CGI-I) measures change in the patient’s presentation from baseline. Scores range from 1 (very much improved) to 7 (very much worse). A score of 4 indicates no change.... clinical global impression

(OSCE) a type of examination used increasingly in the health sciences (medicine, dentistry, nursing, physiotherapy, pharmacy) to assess clinical skills in examination, communication, medical procedures, and interpretation of results. The examination usually takes the form of a circuit of stations around which each candidate moves after a specified time interval (5–10 minutes) at each station. Stations are a mixture of interactive and noninteractive tasks. Some have an examiner and a simulated patient, either an actor for assessment of communication or history-taking skills or a manikin of a specific part of the body (e.g. to demonstrate how to use an auriscope). Other stations have investigation results with a list of questions that are to be completed on computer-marked examination papers. Each station has a different examiner and the stations are standardized with specific marking criteria, thus enabling fairer comparison with peers.... objective structured clinical examination
(OAD, King–Kopetzky syndrome) hearing difficulty, especially in noisy environments, in an individual with a normal *audiogram: a form of *auditory processing disorder. Treatment includes *hearing therapy.... obscure auditory dysfunction
