Emergency Room Wait Time Summary

Better Essays
The article that I have chosen discusses the analysis of emergency room wait time issues via computer simulation. The analysis was made by John T. Blake and Michael W. Carter from the Department of Mechanical and Industrial Engineering at the University of Toronto. Many patients want to receive treatment as fast as possible and despise the idea of waiting. Although the article was written in 1996, the problem with long emergency room wait time still occurs today even at the most modern and advanced hospitals. Even with the many measures that have been implemented in the hospitals to reduce waiting time and prioritize patients with an emergency situation, it is still impossible to please every single patient. According to the study that …show more content…
This caused delays in the delivery of primary care and not all of the requests could be accommodated in a timely manner. The amount of workload that a casualty officer received also proved to be another factor that increased patients’ waiting time. Casualty officers are typically responsible for the care of five or six patients. Besides that, they are also responsible for supervising one or two medical residents. As a result, casualty officers have to finish determining at least one patient’s final disposition, while observing and directing residents before they can see another patient.

The Phase II of Blake’s and Carter’s observation study involves constructing a simulation model and identifying any critical factors. The simulation model was validated against actual data from the hospital to ensure that it was capable of reproducing the function of the emergency room. A 2k factorial experiment was designed to quantify the issues that were believed to affect patient wait time. Using the analysis of variance (ANOVA) techniques, it was evident that casualty officer and resident availability and the interaction between them are significant components of patient wait

Just like what was mentioned in a case study conducted by Albert Felix Imahsunu, in manufacturing industries, the focus of production control is on the flow of materials. However, in hospitals and other similar institutions, the most important process is the flow of patients, while the flow of materials is secondary. Imahsunu further explained that production control has specific requirements that the factory has to follow to make the end-products and a set schedule for the delivery, whereas for the healthcare industries, there is rarely a fixed standard for product specifications. Not only do the highly trained professionals (medical specialists) generate requests for service, but they are also involved in delivering the service (Imahsunu, 2014, p. 16). Also, medical care is not something that can be stocked and put as

    In doing research, one tends to find several “causes” for the current nursing shortage, but hospital administrators are still not in agreement regarding any one main cause. Hospitals and researchers have no idea what could be the cause. All that is known is that ”Prolonged shortages also might reduce the quantity of patient care, increase operating and labor costs, and decrease the efficiency and effectiveness of care provided” (Buerhaus et al.). With the cause being unknown, it becomes even harder to keep nurses in the work…

    More and more are rooms getting used for other then its purpose, doctors using the staff to help with their procedure because they do not want to call extra staff in. This causes a longer wait time and probable using that staff to help triage, or help with a critical patient. Nothing can be done about it because of politics of either hospital or state. Another statement that is similar as to the previous “Use of the ED continues to grow, while the number of ED declines.” Also tries to justify that that even though the rooms are constantly filled, but are they really being used for what it meant to? No because even though out patient procedure happen which is…

    In Doctor’s Hospital because of the lack of the decision-making it started facing information systems challenges. First, there were backlogs in both emergency department (ED) and outpatient areas. Secondly, enhancing capacity management software could interrupt or to slow down the existing flow process of Hospital’s construction. Finally, project steering committee which is the most important for system acquisition is stalled. Therefore, system acquisition interrupted mostly because of the absence of a full-time…

    Because each patient isn’t given the proper attention, it is extremely difficult to accurately monitor the patient, leading to failure to observe the patient’s changing condition. The structure of a chaotic environment affects all members of the ED, while physicians are feeling pressured to assess and evaluate as many patients as humanly possible, leading to unsafe discharges. Oftentimes, these unsafe discharges are witnessed by their nurses, but have too many tasks to get done to realize their patients have even been discharged. This leads to the failure to question patient discharge, which is one of many critical responsibilities nurses must adhere…

    The patient movement and available beds are a major issue, not only in the ED, but in the entire hospital. A patient can not be moved to a unit that is full, or one that does not have enough nurses to care for said patient. The admitted patient awaiting transfer remains in the ED’s bed and care, which impedes the flow of new patients and consumes valuable resources, including the ED nurse. Many people would jump to the conclusion that if the hospital just increased the department’s staff, then it would simply compensate for the increased amount of patients. However, the problem isn’t that simple.…

    The study discovered that orders written on paper caused an increase in wait times and delays in diagnosis due to not being able to properly read the order. (Taner, Sezen, Atwat 274-290). The next contributor is that doctors are placing unspecific orders. For example, they are ordering a CT scan of the chest but not specifying if it is to be with or without contrast. When the nurses contact the scheduling department, they are often guessing at the contrast requirements.…

    The patient would often change their mind and require extra talking to in order to relay their needs to other treatment team members. Having various health issues made this a more complex case than some others. Unfortunately with psychological and addiction issues, patients, including this one, are often seen back within months if not weeks with the same medical diagnosis in which they were previously admitted for. Watts, Steveson, and Adams (2017), found that patients with low health literacy have more hospital readmissions and use the emergency department more often. From a healthcare standpoint, readmission is an occurrence that is avidly avoided but in cases such as this one, are frequently…

    However, doctors are the ones that focus on patients’ symptoms, not what is in their pockets. It is true that inside an office, doctors care for patients, yet the time to get there can be tedious. Since healthcare is an expensive system, doctors can be picky at which insurance to accept. This can prolong the illness and discourage patients from seeking treatment. Growing up I have personally experienced such dilemma.…

    The complexity in providing care to Geriatric patients who experience many challenges both medical and psychosocial issues – can’t see, can’t drive, can’t remember, can’t get up and down, can’t pay bills, too many specialists, can’t keep track of medications.

More than ever, I often feel the sense of powerlessness when I take care of some patients.
