Wait Times in Outpatient Centers Compared to Traditional Emergency Rooms

It is reasonable to suggest that many if not most people find themselves in need of urgent medical care at some point in their lives and until a few years ago, the traditional emergency room was the only option available. Over the past 20 years or so, though, there has been an explosion in the number of outpatient centers that provide a wide range of urgent medical care including various surgical procedures. This growth in the number of outpatient centers has resulted in an increased interest in determining how efficient these respective healthcare venues are in treating patients. To this end, this paper reviews the relevant literature concerning traditional emergency rooms and outpatient centers and proposes a strategy for recruiting and selecting a sample population to compare the average waiting times for each. An overview of the characteristics of the target and accessible populations is followed by a description of the proposed sampling strategy with its strengths and limitations. A discussion concerning the proposed recruitment plan is followed by a description of the inclusion and exclusion criteria that will be used for sample selection. Finally, an assessment of relevant contextual factors regarding the proposed setting of the study is followed by a summary of the research and important findings concerning the foregoing issues in the conclusion.

Characteristics of Target and Accessible Population

The scenario is probably familiar to any healthcare consumer who has sought medical care in a traditional emergency room. In all likelihood, there will be dozens of patients and their family members waiting for care and even if a consumer is fortunate enough to find an emergency room that is not crowded, the potential for new cases to arrive at any second means that waiting times can be extended indefinitely for non-life threatening cases. In this regard, Alijani and Kwun (2015) emphasize that, "Without a doubt, when looking at healthcare reform, we cannot overlook the problem of overcrowding and lengthy waiting times in most emergency rooms" (p. 2).

Lengthy waiting times in emergency rooms adversely affect the level of patient satisfaction (which is an area of quality concern for accrediting organizations such as the Joint Commission), but they also create a situation in which patients tend to experience higher levels of suboptimal clinical outcomes as well. For instance, Alijani and Kwun add that, "Long waiting times not only affect patient satisfaction, they increase the risk of death and hospital readmission for patients who have been discharged from the emergency department" (p. 2). Despite efforts to reform the healthcare system in the United States, most authorities agree that many Americans, especially those without health insurance, will continue to rely on emergency rooms as their primary source of medical care in the future (Alijani & Kwun, 2015).

Some indication of the extent of the problem can be discerned from the most recent statistics reported by the U.S. Centers for Disease Control which are set forth in Table 1 below.

As can be seen from the statistical breakdown in Table 1 above, just over one quarter (27%) of the 136.3 million emergency room patients treated in 2011 were seen within 15 minutes of their arrival, and it is reasonable to posit that these cases were the most severe, arrived by ambulance and/or occurred during extremely rare periods of low demand. It is noteworthy that just around 29% of the emergency room visits shown in Table 1 above were injury related, indicating that the a significant percentage of healthcare consumers seeking care at emergency rooms do so for alternative reasons. For example, studies have shown that 13% of emergency room patients are malingering with secondary objectives most often including obtaining food, shelter, prescription drugs, financial gain, or the avoidance of jail, work, or family responsibilities (Brady, Schur & Newman, 2013).

There are some other factors that can create inordinately long waiting times at emergency rooms as well. For instance, Hsia, Kellermann and Shen (2011) report that:

health care system, hospital emergency departments (also known as emergency rooms [ERs]) are unique in their legal obligation to treat all patients in need, without regard for their ability to pay. As a result, emergency rooms often serve as the 'safety net of the safety net,' offering a place of last resort for uninsured and underinsured patients who lack other options for care. (p. 1)

In fact, even some insured patients may opt for medical care at an emergency room when they are required to wait inordinately long periods of time for appointments from their primary healthcare providers. In this regard, Kovner and Knickman (2005) point out that, "Medicaid patients have historically adapted to long wait times for appointments at some clinics and outpatient departments (60 days or more in many cases) by using emergency rooms for routine care" (p. 619). These statistics indicate that waiting times at virtually any emergency room are highly unpredictable and that treatment may be delayed for all but the most critical cases at any given time. A typical emergency room waiting room is depicted in Figure 1 below.

Against this backdrop, it is little wonder that healthcare consumers would be interested in a more efficient alternative, especially for urgent care needs that do not require tertiary healthcare services and these issues are discussed further below as they relate to the burgeoning outpatient clinic industry.

The majority of surgeries that are performed in outpatient clinics in the United States today involve the eye, ear, nose/mouth/pharynx, and skin (Wier & Steiner, 2015). In fact, the outpatient clinics were the venue for a majority of surgeries performed in the United States in 2011 on the ear (91.8%), nose/mouth/pharynx (86.7%) and skin (76.1%) (Wier & Steiner, 2015). By contrast, the majority of obstetrical surgeries (97.7%) were performed in inpatient settings and just 2.3% were performed in outpatient clinics (Wier & Steiner, 2015). Likewise, cardiovascular and respiratory surgeries were only performed in outpatient clinics 28.3% and 13.1% of the time in 2012, respectively (Wier & Steiner, 2015). At present, there are approximately 10,000 such outpatient clinics operating in the United States (Urgent care center vs. emergency room, 2016) compared to about 1,779 emergency rooms (Hsia, Kellermann & Shen, 2011). A typical outpatient clinic waiting room is depicted in Figure 2 below.

As noted above, the average waiting time for receiving emergency medical care can have a profound impact on the quality of clinical outcomes. Calculating the precise average respective waiting times for emergency rooms and outpatient clinics, though, is complicated by a number of factors. For instance, according to one industry analyst, "The average emergency room has a wait time of 2.4 hours, whereas urgent care centers are able to see walk-in patients within 15-45 minutes. However, that wait time does not express the time patients will spend waiting for services while in the doctor's office" (Urgent care center vs. emergency room, 2016, para. 4).

Nevertheless, ceteris paribus, patients will typically been seen faster in outpatient clinics because the services they offer are more specialized and limited (Urgent care center vs. emergency room, 2016). As also noted above, waiting times in either venue can vary depending on the exigencies of the day, and the potential for more urgent cases to arrive just as a patient is about to be seen exists irrespective of whether the setting is an emergency room or outpatient clinic (Urgent care center vs. emergency room, 2016). In this regard, one industry analyst emphasizes that, "Depending on the number of people waiting and the severity of sickness or illness, the wait can be as little as a few minutes or as long as a few hours" (Urgent care center vs. emergency room, 2016, para. 5).

As noted above, however, the likelihood that individuals will be seen and treated more rapidly in outpatient clinics compared to traditional emergency rooms is clear: "That said, most urgent care patients wait less than 15 minutes while the average emergency room patient waits over 2 hours" (Urgent care center vs. emergency room, 2016, para. 5). Moreover, the potential for adverse clinical outcomes in emergency room settings increases as overcrowded conditions increase. In this regard, Kilcoyne and Dowling (2010) stress that, "Overcrowded emergency departments are a high risk environment for medical errors and pose a threat….....
