  • What is a medical record? A medical record is a confidential record that is kept for each patient by a healthcare professional or organisation. It contains the patient's personal details (such as name, address, date of birth), a summary of the patient's medical history, and documentation of each event, including symptoms, diagnosis, treatment and outcome. Relevant documents and correspondence are also included. Traditionally, each healthcare provider involved in a patient's care has kept an independent record, usually paper based. The main purpose of the medical record is to provide a summary of a person's contact with a healthcare provider and treatment provided to ensure appropriate healthcare. Information from medical records also provides the essential data for monitoring patient care, clinical audits and assessing patterns of care and service delivery. In the current environment the medical record also forms the first link in the information chain producing the depersonalised aggregated coded data for statistical purposes. As every health professional, coder, manager and patient knows, considerable effort is invested in writing, filing, sorting, searching, retrieving, issuing and recovering the medical record, in whole or in part. There is no doubt that the ready availability of well organised, legible, accurate and comprehensive clinical notes can play a very significant role in the clinical decision making process and assisting in the provision of quality healthcare.
  • The Good European Health Record Document ID: Requirements for Clinical Comprehensiveness Version: 1.3 Document Date: 8.1.93 Workpackage: 1-4 2 The Historical Background of Clinical Records Some of the oldest surviving examples of medical recording are papyri from ancient Egypt which contain details of surgery and prescriptions. There has always been a recognised need for those involved in healing or treatment to pass on details of successful procedures or potions either by written methods or through an oral tradition. It is also likely that individual practitioners attempted to describe what they saw and what they did but this was not a widespread practice. The earliest surviving records that describe individual patients in the United Kingdom belong to St Bartholomew’s Hospital and date from its foundation in 1123 AD 1. This was in the reign of Henry I who established the first public records office in England. By the mid nineteenth century individual physicians often kept some notes about their patients but these were usually kept in books according to physician, one book for each year, with the patients filed in alphabetical order. This chronological method of recording meant episodes of illness were considered in isolation. As people became more interested in the cause of illness, the importance of reviewing past events was realised. In 1907 St Mary’s Hospital started a system of unit notes where the patient and not the disease episode became the unit for record compilation. The unit record received extensive development and evaluation at the Presbyterian Hospital in New York where it was implemented in 1916.
  • In 1969 Weed published a book "Medical records, medical education and patient care“ which introduced a method of structuring a record, the Problem Orientated Medical Record (POMR) 10. This was a format for clinical recording consisting of a problem list, a data base (that is, the history, physical examination and laboratory findings), and then, written out separately for each problem, a plan (diagnostic, therapeutic and educational) and a daily SOAP (subjective, objective, assessment and plan) progress note. The problem list was kept at the front of the medical record and served as an index for the reader so that each problem could be followed through until it was resolved. This system widely influenced note keeping by recognising the four distinct phases of the clinical decision making process: data collection; formulation of problems (not necessarily diagnoses); devising a management plan; reviewing the situation and revising the plan if necessary. However the POMR was not widely adopted exactly as Weed proposed because it proved to be too time consuming. The individual note entries were classified according to problem but were still entered sequentially in date order, making it a time consuming process to acquire a retrospective picture of events within one problem 11 CLICK The electronic health record is a life to death record, containing summary information about key health and healthcare related events. CLICK It will contain some key personal clinical characteristics which don’t change much – if at all - over time. For example blood group, allergies etc CLICK We see the EHR getting populated from a variety of different sources. CLICK So over the life of an individual we can imagine various health, healthcare or life events happening – in early years there will be important information about vaccinations etc. Where there may be a more substantial event takes place – for example a case of appendicitis – then as well as basic information about the event a small block of more detailed information may be attached to the EHR record. CLICK Events continue over time, building up the life to death record.
