Forecasting is often defined as the estimation of the value of a variable (or set of variables) at some future point in time (Goodier, 2010). It can be applied to a number of different situations when there is uncertainty about the future and the data collected can aid in decisions that need to be made (Armstrong, 2001). In relation to healthcare, forecasting models have been used to aid their sector’s departments to plan staff rota schedules, ensuring that a sufficient amount of senior staff are available at any given time throughout the day, week, month and year. As explained previously, a fundamental factor that causes overcrowding is a limited supply of resources to treat patients, leading to a longer time spent in an Emergency …show more content…
These models can be characterised as consisting of a time trend, a seasonal factor, a cyclical element and an error term (Kennedy, 2008.) Unlike casual or economic forecasting, where it is assumed there is a historical relationship between a dependent and an independent variable will be consistent in the future, time series models assume the historical components of the model will repeat itself. Research has been undertaken to develop a generalised forecasting model that uses a method that can accurately predict future the attendees and resources needed at Emergency Departments.
1.3.3 Long Range Forecasting for Future Attendees An early attempt to predict attendees was conducted by Milner (1988) who’s study on a single Emergency Department within the UK attempted support to healthcare planning by forecasting annual first, return and total attendances at EDs for Trent districts and the whole of the Trent region. The data of annual first, return and total attendances were collected over a training period of 10 years and evaluated over a period of 1 year using an Autoregressive Integrated Moving Average (ARIMA) method for modelling which falls into time series model category. This method for forecasting this type of data has been supported by other researchers, who state that ARIMA forecasting techniques should be considered for a time series that’s contains a trend or seasonal or non-stationary data. The results
Appropriate nurse staffing is a complex topic that has arisen as a nationwide healthcare issue within the profession of Registered Nurses (RN). To truly understand the concept of staffing one must understand that staffing and scheduling are often at times used interchangeably although Mensik (2014) noted a distinct difference between the two (p. 2). The American Nurse Association [ANA] (2012) has defined appropriate nurse staffing “as a match of registered nurse expertise with the needs of the recipient of nursing care services in the context of the practice setting and situation” (p. 6). Scheduling, in contrast, involves taking into account factors such as a unit’s historical census numbers along with anticipated surgical volumes
A visit to the emergency department (ED) is usually associated with negative thoughts by most people. It creates preconceived images of overcrowded waiting rooms and routine long waits for treatment (Jarousse, 2011). From 1996 to 2006, ED visits increased annually from 90.3 million to 119.2 million (32% increase). During this same time period, the number of EDs has declined by 186 facilities creating the age old lower supply and greater demand concept (Crane & Noon, 2011). There are many contributing factors that have led to an increase in ED visits. A few of these key drivers include lack of primary care access, rising of the uninsured population, dwindling mental health services, and the growing elderly
In the first medical surgical unit, it is forecasted there will be 14,007 patient days in 2015 with the 5:1 ratio, there needs to be 2,802 staff members in this unit. In the second medical surgical unit, there will be 14,086 patient days in 2015 and will need 2,817 staff members. The third unit will have 10,846 patient days and will need 2,170 staff members to meet the standard ratio. The final unit will have 9,936 patient days in 2016 and will need 1,987 staff members.
| "Dynamic models, usually computer-based, that allow the forecaster to make assumptions about the internal variables and external environment in the model" is a definition for which of the following forecasting methodologies?
Assess the current Models of Care in their Emergency Departments using the given criteria It is recognised that not all of the Models of Emergency Care are applicable for all NSW Emergency Departments. Decisions to implement them will be made based on the staff, patient presentations and space available in the ED to operate each model. Assess the potential to introduce models to their hospitals that may improve patient care and flow, the patient experience and clinical outcomes
14 million Canadians visit Emergency Departments (ED) every year, and also reported to having the highest use of EDs (Ontario Hospital Association, 2006). ED overcrowding in Canada has become an epidemic. ED overcrowding has been defined as “a situation in which the demand for emergency services exceeds the ability of an (emergency) department to provide quality care within acceptable time frames” (Ontario Ministry of Health and Long Term Care, 2014). This has been an ongoing problem across Canada. Ontario has developed an initiative to reduce ED wait times by implementing a variety of strategies and collaborating with other institutions. This paper describes the Emergency Room National Ambulatory Intuitive (ERNI), an
Queuing is feature of our daily life, whether in an airport, a post office or Emergency Departments(ED), few of us wishes to wait too long for service. The clinical cost of waiting too long for urgent treatment in an ED is all too long for service. Following media headlines, pooled with powerful political agenda lead to, in the late 1990s and the early 2000s many ED in the UK were struggling with high demand and poor patient flow. During this period it
The additional revenues that were collected due to increase in ICU capacity by 20 beds enhanced the total ED revenues by 10%.4 The efficiency of care delivery is decreased when patients are diverted to other hospitals, they have to wait for long period to receive care or if they are placed on the floors where they do not belong. This is seen often due to delay in discharging patients.3 These delays and inefficiencies are the primary cause of decreased satisfaction among patients, their families, hospital employees, and physicians. They also result in avoidable increases in patient length-of-stay, reduced quality of care, and lost or diminished hospital revenue.3
Hospital emergency room wait times are the talk of the United States right now. Long wait times can contribute to the problems that decrease the quality of our health care system. Emergency room wait times depend on how busy the day is going, how long it takes for each patient to be seen, and how much staff is on duty. Wait times are also based on your injury as well. If you are there for a broken toe versus a head injury, you are going to be seen after the patient with the head injury despite the fact that you were there first. A case study researched and and written by Kevin Tuttle explains a challenge with a mission to decrease the wait times in the emergency room department.
The SST will require data collected from all computers used to monitor access to the admission system. Additional data will have specific times at which the patient reported to various stations of treatment, and when the patient was discharged. A multivariate trend forecasting method will be more appropriate in this setting; the use of multiple variables about the item being forecasted allows seasons and cycles to be combined with other variables and improve forecast accuracy (Langabeer, 2008). This will give operation managers better forecasting abilities as they will be able to see trends.

This research is trying to answer the question of how to reduce overcrowding in emergency rooms? Would people would want to access published wait times provided on the internet, and would this guide a patient make decisions on where they receive their care. The hypothesis being one, crowding maybe reduced with having upfront information, and therefore also provide increased patient satisfaction due to waiting less. Patients would have more choices available to them such as

Forecasting involves using past data to generate a number, set of numbers, or scenario that corresponds to a future occurrence. It is absolutely essential to short-range and long-range planning.
Business forecasting is the process of studying historical performance for the purpose of using the information gained to project future business conditions so that decisions can be made today that will assist in the achievement of certain goals. Forecasting involves taking historical date and using it to project future data with a mathematical model. Forecasts are extensively used to support business decisions and direct the work of operations managers. In this paper I will introduce different types of forecasting techniques.
