Session 1: Organization of Health Related Data Using Computer Packages Learning Tasks By the end of this session students are expected to be able to: • Explain concepts of electronic data storage and arrangement • Demonstrate electronic filing and application of security to electronic data • Explain the methods of summarizing data What is Data Storage • Data storage Data storage is the recording (storing) of information (data) in a storage medium. Numerate four (4) storage media i. Handwriting ii. Phonographic recording iii. Magnetic tape iv. Optical discs List four (4) electronic Data storage formats i. Music ii. Video iii. Document iv. Pictures HMIS NOTES B.Boy List five (5) storage devices i. CD ii. DVD iii. Internal Hard disk iv. External Hard disk v. Flash vi. FDD vii. Memory card Numerate Three (3) common type’s data storage i. Hard drive ii. USB flash drive iii. Memory card. Explanation of each type of Storage • Hard drive (HD) o The term "hard drive" is actually short for "hard disk drive." o The term "hard disk" refers to the actual disks inside the drive. o The hard drive is a non-volatile memory hardware device that permanently stores and retrieves data on a computer. Non-volatile memory is a term used to describe any memory or storage that is saved regardless if the power to the computer is on or off. The best example of non-volatile memory and storage is a computer hard drive, flash memory, and ROM. HMIS NOTES B.Boy o A hard drive is a secondary storage device that consists of one or more platters to which data is written using a magnetic head, all inside of an air-sealed casing. o A typical hard drive is only slightly larger than a human hand and can hold over 100 GB of data. • USB flash drive o A USB flash drive is a device used for data storage that includes a flash memory and an integrated Universal Serial Bus (USB) interface. o Most USB flash drives are removable and rewritable. o Physically, they are small, durable and reliable. o The larger their storage space, the faster they tend to operate. o USB flash drives are mechanically very robust because there are no moving parts. o They derive the power to operate from the device to which they are connected (typically a computer) via the USB port. o A USB flash drive may also be known as a flash drive or USB drive. • Memory card o A memory card is a type of storage device that is used for storing media and data files. o It provides a permanent and non-volatile medium to store data and files from the attached device. Define the Term Memory Card Memory cards are commonly used in small, portable devices, such as cameras and phones. List five (5) most popular forms of memory cards are: i. Secure Digital (SD) card ii. Compact Flash (CF) card iii. Smart Media iv. Memory Stick v. Multi Media Card (MMC) HMIS NOTES B.Boy In the healthcare system, data are store in the electronic systems, and these systems are called electronic health records (EHR) and electronic medical records (EMR) Define the following Terms • Electronic Health Records o An electronic health record (EHR) is a digital version of a patient’s paper chart. o It contains a patient’s medical history, diagnoses, medications, treatment plans, immunization dates, allergies, radiology images, and laboratory and test results in electronic format. o It is health information that is created and managed by authorized providers in a digital format capable of being shared with other providers across more than one health care organization. • Electronic Medical Records o Electronic medical records (EMRs) are a digital version of the paper charts in the clinician’s office. o EMR contain medical information used by clinicians mostly for diagnosis and treatment.. o An EMR contains the medical and treatment history of the patients in one practice. o Information in EMRs cannot easily be shared out of the medical practice. o The patient’s record can easily be printed out and shared with other members of the care team. HMIS NOTES B.Boy ELECTRONIC FILLING Filling A filing system is a plan or method of arranging documents in a prescribed order. The purpose of filing documents is to enable a quick retrieval of complete information Whenever it is required. Requirements of a good filing system o Simplicity-The filing method must be easy to understand and simple to operate. o Easy access-Documents should be easily identified and located to enable speedy pulling and filing. o Security-Documents should be safely kept and well preserved. o Tracer system-The whereabouts of documents removed from the storage must be known. Methods of Filing in Medical Records There are four common methods of filing patient records used in health facilities o Alphabetical o Chronological o Geographical o Numerical HMIS NOTES B.Boy Explanation of each method Alphabetical Filing System • Alphabetical filing is a very commonly used method for filing in general. • Examples of alphabetical filing system are, Abdallah, followed by Bakari, then Charles. Chronological Filing System Chronological filing means filing in time order. • It is used in combination with another method. • Letters for example are usually filed alphabetically according to name or subject and within each group in date order. Example of chronological filing system is, those patients who are expected to be admitted on 14th February 2010, Abdallah/14, Bakari/14, Charles/14. The 14 is a filing position in filing waiting list. • The waiting list is having filing position from 1 up to 31 according to dates. Geographical Filing System Geographical filing is based on geographical units like countries, regions, and town. • Very often it is
