The Rationale behind Your Design Development
CPOE- Computer Provider Order Entry, along with Clinical Decision Support can enhance the safety of medicine prescription (Kuperman, et al., 2007). The rationale for the development of the physician order entry with CDSS comprises of process enhancement, support for cost-based decisions, support also for clinical decisions, as well as optimization of physicians' timeframe. Also, CPOE with CDS systems is considered one of the best ways to enhance health care service and improved safety of the patients. When the electronic records of the patients become increasingly accessible, the systems will inevitably become the method that medical care staffs will choose. It is a complex process creating a CPOE/CDS system. Indeed, some of them fail even after consuming a lot of resources and time.
How to Implement the CPOE/CDS System
CPOE presents many advantages and disadvantages. If it is not implemented in stages, one is likely to experience the full extent of its pitfalls. It must start with viewing it in the laboratory. The next steps include addition of dictations, viewing of images, basic chart and eventually graduated to CPOE system on form. Even with such pre-implementation precautions, the system can still confuse physicians...
Practicum Objective There is a high degree of interrelation between theory, practice and research. Research is the starting point. It involves the gathering of knowledge, and then this knowledge is used to build theories. The theories are then put to the test, first in the research process and then if that is successful theories are put into practice in the real world. Real world practice then becomes the basis for the
Reducing Patient Waiting Time for Better Patient Outcomes Step 1 Most healthcare institutions start their day with the intention of perfectly managing their time schedules. While the expected outcome is excellent patient outcome many practices often end up bringing in more patients into a schedule that is already overloaded hence requiring more time to attend to the scheduled patients (Capko, 2015). The outcome of the busy schedules is inefficiency, bottlenecks, frustration, and
Ethics in EOL Decisions Finding Common Ground in EOL Care Decisions Churchill (2014) presents to readers a case study to highlight some of the ethical and moral issues that will occur during end-of-life (EOL) decisions. The case study is not a factual event, but represents the mean severity and complexity of the EOL struggles experienced by the typical stakeholders. In this example, the treating physician has unsuccessfully tried to convince the adult
Patient Handoffs Majority of the medical errors take place in the patient's handoffs. A shift among the doctors is a common practice. There are a number of old patients who approach around 16 different doctors in a year, while young patients who are healthy refer to normal physicians and to specialists as well (Philibert, 2008). In a hospital normally, less attention is given to the patient by his primary doctor, while
Many advocates of the move feel that lower patient to nurse ratio would lead to additional savings because it would reduce nurse turnover rate, lawsuits, complications and length of stay. Nursing unions in the state of California have asked for a PTN ratio of 3 to 1. The health association however agreed on 5 to 1 which sound more reasonable than the originally proposed 10 to 1. (Rothberg, 2005) Patient
patient falls in U.S. healthcare institutions is staggering. They increase insurance costs, staff pressure, and even more accidental injuries other than falls. Research has shown that there are a number of ways patient falls may be mitigated: more nursing rounds, patient exercise, and body awareness conditioning. Tai Chi is a Chinese martial art that is practices for both defense training and health benefits, as well as longevity. The overall
