Background: Emergency departments (EDs) serve as an accessible gateway to healthcare system wherein numerous patients consider it a prime choice for medical complaints. Frequency of ED revisits, causes, and its burden are necessary to assess quality of care provided to patients and identify factors that leads to revisit.
Patients and Methods: Electronic and printed medical records of all patients who revisited ED from January to May 2016 within 72 hours of initial visit were reviewed. Patients’ cause of revisit were classified to three categories: patient-, physician- and system-related factors. Common complaints that require revisits were also collected. Descriptive analysis was performed and categorical variables were represented by the frequency; percentages and continuous variables were presented as median, and range if data did not follow normal distribution.
Results: Of the 79,279 patients who visited ED during the study period, 1.3% (1000) patients revisited within 72 hours; 51.3% (n=513) were males, with a mean age of 31.5 years (SD=17.7 years) where majority (57.1%) had no comorbidity recorded. The most attributed factors for revisit were as follows: patient-related causes 635 patients (63.5%), physician-related factors 167 patients (16.7%), and system-related factors 42 patients (4.2%); 15.6% were found not related to the initial visit. Recurrence of the same complaint was the highest among patient-related factors (80.5%), inadequate management and no improvement of symptoms in 71.3% among the physician-related factors. The most common ED revisit complaint was fever 29.1% (n=291). Outcomes of the revisit were mainly patient discharge 96.7% (n=967), admission 1.2% (n=12) and death in 0.2% (n=2).
Conclusion: Recurrence of the same complaint with no symptoms improvement and suboptimal management of physicians contributed to most of the ED revisits within 72 hours. Encouraging physicians to provide clear instructions in educating patients on discharge regarding disease progression and its red flags as to when a return to ED, might help in reducing revisit rate.

Introduction

Emergency Department (ED) return visit is a known quality indicator for patient care and safety in EDs worldwide. Patients returning to the ED within a short period from initial presentation contribute to overcrowding1–4 which leads to delayed treatment, patient displeasure, waste of ED resources and increased costs of health care.1,2,5,6

Patients who return to the ED within 72 hours of discharge are often recognized to have received inappropriate treatment or evaluation.7 Return visit rates of more than 5% may reflect poor quality of care, and rates less than 1% indicate undue risk aversion.8 ED return visits within 72-hours can be categorized into three groups, namely: illness-related, physician-related and patient-related ED returns.9 In illness-related ED returns, the patient receives appropriate medical care, but disease progression causes the ED return visit. In physician-related ED returns, the patient returns due to the physician’s misconduct. Unexpected ED return visits were found to be associated with medical errors in treatment, follow-up care, prognosis, and information.10 In patient-related ED return visits there is no clear evidence of lapses in medical care and return visits are mainly patient-initiated. However, it is difficult to differentiate between the disease course nature, sub-optimal therapy, patient anxiety, and medical error misbehavior as the cause of the ED return visit.11 Other factors such as increasing age of the patient, illness severity, and inexperienced or junior physicians were found to be associated with ED return visits.10,12–16

One study conducted at a hospital in Canada on ED return visits showed that of the 9935 ED visits, 289 (2.9%) were within 72 hours. Most unscheduled ED return visits were classified as low-acuity (45.3%), and in most of them (88.6%), patients were treated in the ED and discharged home.17 Another study by Lerman and Kobernick reported that of the 64,336 ED visits during the period of the study, 255 returned to ED within 72 hours. Of them, 83 (32.5%) ED return visits were avoidable by better education of patients or medical care on the initial visit.18

With rising ED return visit rates, there has been an increasing need to address the problem of overcrowding.19,20 Analyzing factors associated with ED return visit will help in decreasing avoidable ED return visits and reducing the financial health care burdens. The global data propose that a rate of early ED return visits of approximately 3% is an acceptable estimation of the average international return visit rate.21 However, there is a debate in the literature about the acceptable rate of ED return rates and the factors associated with ED revisits. The time span of early ED return visits may identify the rate of early return visits to the ED. Longer time spans increases the rate of early ED return visits and include patients who are either frequent attendees, with chronic disease, or unrelated attendance. Most of the studies used a 72-hour period between initial and following visits.21 Furthermore, some studies included all early ED return visits with both related and unrelated diagnoses,11,22,23 and other studies included only early ED return visits with related diagnoses.13

In this study, we aimed to identify the rate and characteristics of return visit at our ED within 72 hours from the initial visit and to determine clinical and demographic factors that include patient age, acuity of triage level, and presence of comorbidities, clinician education level and diagnoses. Likewise, we also hope to determine the underlying factors associated with unscheduled ED return visits and thereby help the application of strategies to address overcrowding, communication improvement and promote patient care.

Patients and Methods

Study Design and Setting

A retrospective observational study where electronic and printed medical record review of all patients who revisited the emergency department of King Fahad University Hospital (KFHU)– Eastern province of Saudi Arabia, within 72 hours of their initial emergency visit was conducted. KFHU has an ED annual visit of approximately 200,000 patients per year.

Description and metrics of the department showed patient to staff ratio is 3:1 in the observation unit and 1:1 in resuscitation and trauma area. 46 physicians (24 Saudi and 22 non- Saudi). Time to provider of 26.6 minutes and average length of stay in the department is 2.6 hours.

We chose 72 hours as a revisit cutoff in this study as comparable to previous studies made with similar outcomes and this is only for unscheduled revisits.

Study Duration

The study included patients who revisited the emergency department within the period from January 2016 to May 2016. This five-month period was chosen to overcome the seasonal variation that might influence the revisit rate.

Study Variables

In this study, revisit was defined as the patient visiting the ED after 72 hours from their initial ED visit. Predetermined factors chosen with an agreement by investigating team prior to the study start were used where the revisit reasons were categorized to physician-related, patient-related and system-related factors. Physician-related included suboptimal management defined as misdiagnosis and complications of treatment; patient-related factors included recurrence of same complaints, no improvement of symptoms, and complication of a disease; whereas system-related factors included follow-up, called back for abnormal investigations, unscheduled refill of medication and for admission.

Source of Data

Authors identified patients included in the study within a five-month period using a generated electronic report from hospital patient- visit database. A previously designed and pre-piloted tested data form was used to collect patient data from the electronic and printed medical records by co-investigators who are ED residents and interns (FK, AA, SA, DA, YB) that were trained by the principal investigator (PI). In case of any disparity or clarity, the PI was contacted to resolve the disagreement.

The data form is attached as a supporting information.

Eligibility Criteria

We included all patients who revisited the ED within 72 hours of their initial emergency visit within the study period. All patients were included irrespective of their age or gender. We excluded patients who came after 72 hours and patients who were seen in other EDs, as no previous visit data were available.

Statistical Analysis

All categorical variables were represented by the frequencies and percentages. Data normality was tested by the Kolmogorov–Smirnov test. Variables presented as mean and standard deviation (SD) or median with inter-quartile range (IQR) as appropriate.

Continuous variables were presented as a median and range if the data did not follow the normal distribution.

Results

79,279 patients visited ED during the study period, among them, 1000 patients had to revisit within 72 hours which represents 1.3%. Of those 513 (51.3%) were males, and 48.7% (n=487) were females with a mean age of 31.5 years (SD=17.7 years). Most of patients (57.1%) had no comorbidity, followed by hypertension (11%), and bronchial asthma 10.5%. The demographic characteristics of the study participants are shown in Table 1 while their past medical history is shown in Figure 1.

Characteristics of the Initial Visits and the Revisits

Initial ED assessment of subjects were carried out by residents in training 63.5% (n=635), followed by 13.5% (n=135) assessed by the general practitioners, 11.9% (n=119) by specialists (board certified EM physicians), Consultants (licensed after 3 years of certification) assessed 0.5% (n=5) of subjects, and in 10.6% (n=106) the assessor was unclear during the chart review and that was not statistically significant between both groups p value = 0.569.

The order of treatment was organized based on the degree of urgency with three different triage levels (III, IV, V), the triage level III accounts for 2.7% (n=27), followed by triage level IV with 62.4% (n=624) and the triage level V with 34.9% (n=349) p value = 0.711. The outcome of treatment was assessed with a discharge rate of 95.7% (n=957), followed by discharged against medical advice (DAMA) 0.9%, lack of availability of bed 0.4%, admission of 0.3%.

Most of the revisit patients were of triage category IV with 59.8% (n=594). The outcomes of the revisit to the ED were mainly discharge of 96.7% (n=967), admission of 1.2% (n=12) and death in 0.2% (n=2). The characteristics of the initial visit and the revisits are shown in Table 2.

Table 2 Characteristics of the Initial Visit and the Revisits

Causes and Complaints of the Revisits

Patient-related causes for ED revisits were the most reported attributed factors seen in 635 patients (63.5%), followed by physician-related factors in 167 patients (16.7%) and the least were system-related factors seen in 42 patients (4.2%). The frequencies of physician, patient, and system-related causes of ED visits are shown in Figures 24, respectively.

Figure 3 The frequency of patient-related causes of ED revisits.

Figure 4 The frequency of system-related causes of ED revisit.

The recurrence of the same complaint was the highest among the patient-related factors (80.5%) and suboptimal management and no improvement of symptoms in 71.3% among the physician-related factors. The most common ED revisit complaints were fever 29.1% (n=291), then abdominal pain and vomiting in 12.4% (n=124), followed by body and back pain in 9.7% (n=97), headache in 9.5% (n=95), cough in 8.5% (n=85), trauma in 6% (n=60), dizziness in 3% (n=30), shortness of breath in 2% (n=20) and others 19.8% (n=198).The complaints of initial visits and revisits are shown in Table 3. Furthermore, those factors can be overlapped due to different reasons however, the final determination of which factor was the main cause of the revisit was based on the investigators agreement. Agreement of 100% was observed with regards to inter-rater reliability between physicians who evaluated charts.

Discussion

In this study 79,279 patients visited the ED during the study period. We found that the overall proportion of ED return visits within three days was 1.6%. This was consistent with multiple studies published on ED return visits rates using a determination of return visits of within 72 hours after the initial ED visits, with results ranging between 1.3% to 7.5%.11,13,22–24 Most of these studies included early ED returns using both related and unrelated diagnoses. One retrospective study in Florida and Nebraska published a rate of all ED return visits as up to 7.5%.23 Another study, conducted at a medical center in northern Taiwan, reported that the monthly ED return visit rates ranged from 1.3% to 2.4%.24 Another study at a regional hospital in central Taiwan reported higher monthly rates ranging from 2.85% to 6.25%.11 Keith et al22 reviewed the charts of all ED patients in a US-based hospital; they found that 455 (3.4%) of the 13,261 patients returned to the ED within 72 hours. Another study conducted in Singapore reported a return rate of 2% excluding the returns for unrelated diagnoses.13 Our study showed that both genders have almost equal chances of early ED return visits. In contrast with other studies, where another study in Taiwan on the ecology of medical care published that a higher proportion of men (87.6/1000 vs 81.0/1000) received emergency services in 2005 compared with women.25 Multiple studies found that women were more health conscious and that men usually delay seeking medical help until later stage of their diseases.26,27 Moreover, women may have a lower rate of employment, giving them more time to visit doctors.28

Our study found a mean age of 31.5 years for ED patients who had return visits, where previous study in comparison found that people aged more than 64 years composed the majority of patients with early ED return visits.21 Most of the revisit patients were of triage category IV with 59.8% (n=594) using Canadian Triage and Acuity Scale (CTAS). Resident physicians initially managed 63.5% (n=635) of the revisit patients because the high-acuity patients are generally more unwell and usually seen by senior physicians (specialists and consultants), while the lower acuity patients (category IV) are seen by junior physicians (residents) that may be associated to more ED return visits. These findings were consistent with the previous studies which reported that junior or inexperienced clinicians were associated with ED return visits.12,13 The outcomes of the revisit to the ED were mainly discharged since most of the revisits were category IV in their initial visit. Majority of them had no comorbidities, which is expected due to mean young age in our study compared to other studies, followed by hypertension and bronchial asthma. In our study, the most common ED revisits complaints were fever, then abdominal pain and vomiting, followed by back pain. Recurrence of the same complaint was the highest among the patient-related factors and suboptimal management and no improvement of symptoms in among the physician-related factors. Compared with other studies they found factors associated with higher risk for early return visits ED diagnoses were heart problems, abdominal pain or viral infections.29 Other studies have identified the three greatest risk factors in the 72-hour re-attendees group; they found that heart problems, viral infection, and abdominal pain were the most significant risk factors.9,11,30,31

A literature review on early ED return visits showed that there were variations in the probable causes and that they remain not clearly defined.1,7,9,11,18,22,30,32,33 In the future, we aim to look beyond the index visit and investigate if there was a considerable difference in diagnosis and disposition status between the index and ED return visit. Also, it would be essential to examine admission outcomes of the ED return in the subgroup of 72-hour who were admitted on their return visit, particularly complication rates, as research published showed that patients who are admitted on the ED return visit have poor outcomes.34 We conclude that this study is one of the first to analyze ED return visits in the Middle East population. Our rate of return visit might indicate the quality of care given at the ED. These findings would help in conducting further research as well as directing future strategies to decrease markedly avoidable ED return visit.

We believe that the strength of our study is being conducted in one of the largest and busiest emergency departments in the Eastern Province of Saudi Arabia, with annual visits between 180,000–200,000 visits/year, which gives a good sample to calculate the frequency of revisit rate among population on this region. However, a higher rate of discharge in our department was found and is mostly related to many people with low acuity complaints in this region prefer to go to the ED which is considered easier access than primary health care centers. Nevertheless, as this retrospective study relied on accurate data collection and documentation, interpretation may have been limited by information or selection bias. This study was conducted over a 5 month period however, this cannot guarantee overcoming seasonal variation which can lead to different presentations which might affect the results. During extraction of patient information from files and electronic records, we were unable to obtain some detailed information about some of the patients; we did not have information on some patient characteristics, such as compliance with treatments, socioeconomic status, level of education, and confidence in their primary care, which are associated with ED return visits and might confound the results. And finally, this study was also limited by being a single center experience and no other centers data can be compared. Also there was no evidence that the non-reattenders did not seek other EDs in the region for medical treatment.

Conclusion

In this study, recurrence of the same complaint, no improvement of symptoms and sub-optimal management by the physician, as well as being initially assessed by a resident physician contributed to most of the ED returns within 72 hours. Even though there is no direct evidence of this, accentuating and encouraging physicians to giving patients clear instructions and education on the disease process upon discharge and identifying red flags for when to return to the ED might help in decreasing the revisits rate.
