Health Informatics Assignment Week 10 to 12
Week 10 Questions
- What is meant by the standard view of appropriate use of medical information systems? Identify three key criteria for determining whether a particular use or user is appropriate.
- Can quality standards for system developers and maintainers simultaneously safe-guard against error and abuse and stimulate scientific progress? Explain your answers. Why is there an ethical obligation to adhere to a standard of care?
- Identify (a) two major threats to patient confidentiality, and (b) policies or strategies that you propose for protecting confidentiality against these threats.
- Many prognoses by humans are subjective and are based on faulty memory or incomplete knowledge of previous cases. What are the two drawbacks to using objective prognostic scoring systems to determine whether to allocate care to individual patients?
- People who are educated about their illnesses tend to understand and to follow instructions, to ask insightful questions, and so on. How can the World Wide Web improve patient education? How, on the other hand, might Web access hurt traditional physician–patient and nurse–patient relationships?
Week 11 Questions
- A comparison of different user interfaces for a computer-based medical record system, conducted while the system is under development.
- A site visit by the U.S. National Library of Medicine’s Biomedical Library Review Committee to the submitters of a competing renewal of a research grant.
- A noted consultant on user interface design being invited to spend a day at an academic department to offer suggestions regarding the prototype of a new system.
- Patient chart reviews conducted before and after the introduction of an information resource, without the reviewer being told anything about the nature of the information resource or even that the intervention is the information resource.
- Videotapes of attending rounds on a service where a knowledge resource has been implemented and periodic interviews with members of the ward team.
- Determination of whether a new version of a resource executes a standard set of performance tests at the speed the designers projected.
- Patients being randomly assigned such that their medical records are maintained either by a new computer system or by standard procedures, and then an investigator seeking to determine whether the new system affects clinical protocol recruitment and compliance.
- A mock debate at a research-group retreat.
Week 12 Questions
Limitations of the system: This needs a higher initial expenditure than its paper equivalent attributable to equipment, software, training, and support expenses. The individual and material considerations also control the technical problems. Health professionals and other main staff might just have to take a lot of time off their jobs to understand how to use another program and to change their working environment using the process efficiently. These other problems involved with computer-based systems is indeed the capacity for noticeable and also failures. When the software system breaks down, encryption method can be inaccessible for an unspecified time. Digital records collapse one map at a time. And from the other side, if the typical journal graph were inaccessible up to 10 percent of cases, this will be equal to a 10 percent offline in case of average patient. Acquire of this knowledge explicitly from the practitioner is a major objective of health imaging as it offers another very timely, accurate, and valuable information. Nevertheless, the target is obscure. The time charge of doctor input might become high, so the physician input might be difficult or impossible in certain environments. While new hardware components are developed or enhanced each year none of which has been time-competitive with dictation or handwriting.
- Physicians may enter data directly or may record data on a paper worksheet(encounter form) for later transcription by a data-entry worker. What are two advantages and two disadvantages of each method?
- Discuss the relative advantages and disadvantages of entry of free text instead ofentry of fully coded information. Describe an intermediate or compromise method.
