Risk Factors for Emergency Department Unscheduled Return Visits

Experience of admission and readmission to the emergency department for patients with acute abdominal pain: A qualitative study

BACKGROUND

Abdominal pain is one of the most common complaints when patients are admitted to emergency departments (ED). Unfortunately, many of these patients are readmitted to the ED shortly after initial discharge. The perspectives of these patients have not yet been explored.

PURPOSE

The study aimed to explore how patients readmitted with acute abdominal pain in the ED experienced their initial admission, the time after discharge, and the cause of readmission.

METHODS

The study had a qualitative explorative design with a phenomenological-hermeneutic approach. Semi-structured individual telephone interviews were conducted with 14 patients readmitted with acute abdominal pain.

RESULTS

The analysis showed four themes: 1) being vulnerable during hospitalisation, 2) the meaning of information during hospitalisation, 3) discharged without being diagnosed, and 4) readmitted in the pursuit of relief. The patients wanted more knowledge and better communication despite their vulnerable condition. Patients were discharged whilst still in pain, and uncertainty of the situation at home contributed to mistrust of the health professionals.

CONCLUSION

Patients' experience of the first ED admission due to acute abdominal pain was loneliness, minimal contact with healthcare professionals, and lack of information and involvement in pain management. Discharge was associated with feelings of insignificance and contributed to a fear of death. Pain was the main reason for readmission. Patients described how multiple readmissions contributed to being taken seriously by healthcare professionals.

The risk factors of the 72-h unscheduled return visit admission to emergency department in adults below 50 years old

BACKGROUND

An unscheduled return visit (URV) to the emergency department (ED) within 72-h is an indicator of ED performance. An unscheduled return revisit (URV) within 72-h was used to monitor adverse events and medical errors in a hospital quality improvement program. The study explores the potential factors that contribute to URV to the ED within 72-h and the unscheduled return revisit admission (URVA) in adults below 50 years old.

METHODS

The case-control study enrolled 9483 URV patients during 2015-2020 in National Cheng-Kung University Hospital. URVA and URV non-admission (URVNA) patients were analyzed. The Gini impurity index was calculated by decision tree (DT) to split the variables capable of partitioning the groups into URVA and URVNA. Logistic regression is applied to calculate the odds ratio (OR) of candidate variables. The α level was set at 0.05.

RESULTS

Among patients under the age of 50, the percentage of females in URVNA was 55.05%, while in URVA it was 53.25%. Furthermore, the average age of URVA patients was 38.20 ± 8.10, which is higher than the average age of 35.19 ± 8.65 observed in URVNA. The Charlson Comorbidity Index (CCI) of the URVA patients (1.59 ± 1.00) was significantly higher than that of the URVNA patients (1.22 ± 0.64). The diastolic blood pressure (DBP) of the URVA patients was 85.29 ± 16.22, which was lower than that of the URVNA (82.89 ± 17.29). Severe triage of URVA patients is 21.1%, which is higher than the 9.7% of URVNA patients. The decision tree suggests that the factors associated with URVA are "severe triage," "CCI higher than 2," "DBP less than 86.5 mmHg," and "age older than 34 years". These risk factors were verified by logistic regression and the OR of CCI was 2.42 (1.50-3.90), the OR of age was 1.84 (1.50-2.27), the OR of DBP less than 86.5 was 0.71 (0.58-0.86), and the OR of severe triage was 2.35 (1.83-3.03).

CONCLUSIONS

The results provide physicians with a reference for discharging patients and could help ED physicians reduce the cognitive burden associated with the diagnostic errors and stress.

Predictors of 72-h unscheduled return visits with admission in patients presenting to the emergency department with abdominal pain

BACKGROUND

Unscheduled return visits (URVs) to the emergency department (ED) constitute a crucial indicator of patient care quality.

OBJECTIVE

We aimed to analyze the clinical characteristics of patients who visited the ED with abdominal pain and to identify the risk of URVs with admission (URVAs) from URVs without admission (URVNAs).

METHODS

This retrospective study included adult patients who visited the ED of Taipei Medical University Hospital because of abdominal pain and revisited in 72 h over a 5-year period (January 1, 2014, to December 31, 2018). Multivariable logistic regression analysis was employed to identify risk factors for URVAs and receiver operating characteristic (ROC) curve analysis was performed to determine the efficacy of variables predicting URVAs and the optimal cut-off points for the variables. In addition, a classification and regression tree (CART)-based scoring system was used for predicting risk of URVA.

RESULTS

Of 702 eligible patients with URVs related to abdominal pain, 249 had URVAs (35.5%). In multivariable analysis, risk factors for URVAs during the index visit included execution of laboratory tests (yes vs no: adjusted odds ratio [AOR], 4.32; 95% CI 2.99-6.23), older age (≥ 40 vs < 40 years: AOR, 2.10; 95% CI 1.10-1.34), Level 1-2 triage scores (Levels 1-2 vs Levels 3-5: AOR, 2.30; 95% CI 1.26-4.19), and use of ≥ 2 analgesics (≥ 2 vs < 2: AOR, 2.90; 95% CI 1.58-5.30). ROC curve analysis results revealed the combination of these 4 above variables resulted in acceptable performance (area under curve: 0.716). The above 4 variables were used in the CART model to evaluate URVA propensity.

CONCLUSIONS

Elder patients with abdominal pain who needed laboratory workup, had Level 1-2 triage scores, and received ≥ 2 doses of analgesics during their index visits to the ED had higher risk of URVAs.

Return Rates for Opioid versus Nonopioid Management of Patients with Abdominal Pain in the Emergency Department

BACKGROUND

Research suggests that opioid treatment for abdominal pain, which comprises a large proportion of patients presenting to the emergency department (ED), may contribute to long-term opioid use without significant benefits with regard to symptom management.

OBJECTIVES

This study seeks to assess the association between opioid use for management of abdominal pain in the ED and return ED visits for abdominal pain within 30 days for patients discharged from the ED at initial presentation.

METHODS

We conducted a retrospective, multicenter observational study of adult patients presenting to and discharged from 21 EDs with a chief concern of abdominal pain between November 2018 and April 2020. The proportion of 30-day return visits to the ED for patients who received opioid analgesics was compared with a reference group of patients who only received acetaminophen, nonsteroidal anti-inflammatory drugs (NSAIDs), or both.

RESULTS

Of the 4745 patients, 1304 (27.5%) received opioids and 1101 (23.2%) only received either acetaminophen, NSAIDs, or both. Among those given opioids, 287 (22.0%) returned to the ED for abdominal pain within 30 days, compared with 162 (14.7%) of those in the reference group (odds ratio 1.57, 95% confidence interval 1.27-1.95, p-value < 0.001).

CONCLUSION

Patients given opioids for abdominal pain in the ED had 57% increased odds of a return ED visit within 30 days compared with those given only acetaminophen or NSAIDs. This warrants further research on the use of nonopioid analgesics in the ED, especially in patients with anticipated discharge.

Upstreamist leaders: how risk factors for unscheduled return visits (URV) to the emergency department can inform integrated healthcare

PURPOSE

This paper aims to report on research undertaken in an National Health Service (NHS) emergency department in the north of England, UK, to identify which patients, with which clinical conditions are returning to the emergency department with an unscheduled return visit (URV) within seven days. This paper analyses the data in relation to the newly introduced Integrated Care Boards (ICBs). The continued upward increase in demand for emergency care services requires a new type of "upstreamist", health system leader from the emergency department, who can report on URV data to influence the development of integrated care services to reduce further demand on the emergency department.

DESIGN/METHODOLOGY/APPROACH

Patients were identified through the emergency department symphony data base and included patients with at least one return visit to emergency department (ED) within seven days. A sample of 1,000 index visits between 1 January 2019-31 October 2019 was chosen by simple random sampling technique through Excel. Out of 1,000, only 761 entries had complete data in all variables. A statistical analysis was undertaken using Poisson regression using NCSS statistical software. A review of the literature on integrated health care and its relationship with health systems leadership was undertaken to conceptualise a new type of "upstreamist" system leadership to advance the integration of health care.

FINDINGS

Out of all 83 variables regressed with statistical analysis, only 12 variables were statistically significant on multi-variable regression. The most statistically important factor were patients presenting with gynaecological disorders, whose relative rate ratio (RR) for early-URV was 43% holding the other variables constant. Eye problems were also statistically highly significant (RR = 41%) however, clinically both accounted for just 1% and 2% of the URV, respectively. The URV data combined with "upstreamist" system leadership from the ED is required as a critical mechanism to identify gaps and inform a rationale for integrated care models to lessen further demand on emergency services in the ED.

RESEARCH LIMITATIONS/IMPLICATIONS

At a time of significant pressure for emergency departments, there needs to be a move towards more collaborative health system leadership with support from statistical analyses of the URV rate, which will continue to provide critical information to influence the development of integrated health and care services. This study identifies areas for further research, particularly for mixed methods studies to ascertain why patients with specific complaints return to the emergency department and if alternative pathways could be developed. The success of the Esther model in Sweden gives hope that patient-centred service development could create meaningful integrated health and care services.

PRACTICAL IMPLICATIONS

This research was a large-scale quantitative study drawing upon data from one hospital in the UK to identify risk factors for URV. This quality metric can generate important data to inform the development of integrated health and care services. Further research is required to review URV data for the whole of the NHS and with the new Integrated Health and Care Boards, there is a new impetus to push for this metric to provide robust data to prioritise the need to develop integrated services where there are gaps.

ORIGINALITY/VALUE

To the best of the authors' knowledge, this is the first large-scale study of its kind to generate whole hospital data on risk factors for URVs to the emergency department. The URV is an important global quality metric and will continue to generate important data on those patients with specific complaints who return back to the emergency department. This is a critical time for the NHS and at the same time an important opportunity to develop "Esther" patient-centred approaches in the design of integrated health and care services.

[Risk factors associated with emergency service re-visits in frailty diabetic patients who consult for hypoglycaemia]

INTRODUCTION AND OBJECTIVES

Emergency department (ED) visits due to hypoglycaemia are frequent in elderly patients. The main objective of the study is to evaluate the risk factors associated to ED re-visits at 90days in elderly patients who visited ED with an episode of hypoglycaemia.

MATERIAL AND METHODS

A retrospective observational study was designed, including elderly diabetic patients (>65years) attended in a fragility area of an ED for an episode of hypoglycaemia. To evaluate the risk factors associated to ED re-visits at 90days a multivariate analysis with logistic regression was performed, including those variables related to comorbidity and antidiabetic treatment with a P<0.2 in a previous univariate analysis.

RESULTS

106 patients were included. %HbA1c value was available in 87 (82.1%) patients. Ten (11.5%) patients presented a value of HbA1c ≤5.5%. Antidiabetic treatment was changed to 63 (59.4%) patients at discharge. Thirty-eight (36.1%) patients re-visited the ED at 90days, 9 for glycaemic alterations. The risk factors associated to 90days ED re-visit were: being man (OR: 3.62 [95%CI: 1.24-10.51)), treatment modified at discharge (OR: 0.31 [0.11-0.91]) and to present an HbA1c value ≤5.5% (OR: 5.33 [1.16-14.51]).

CONCLUSIONS

Fragile patients with diabetes who visit ED for hypoglycaemia present, in high frequency, HbA1c values lower than those recommended, being associated to an increase of ED re-visit risk at 90days.

90-Day Return Visit to the Emergency Department After an Initial Neurosurgical Evaluation

OBJECTIVE

This study evaluated emergency department (ED) neurosurgical reevaluation rates and their causes. Identifying the most significant reasons that make patients return to the ED for a neurosurgical reevaluation can help implement changes to reduce the economic and medical burden of patient turnover.

METHODS

All patients undergoing neurosurgical reevaluation at our institution's ED after an initial neurosurgical evaluation were enrolled in a prospective 3-month longitudinal registry. Inclusion criteria were all adult patients 21 years of age or older previously evaluated by neurosurgery at our institution's ED who return within 90 days for a neurosurgical reevaluation.

RESULTS

We found an overall 90-day ED neurosurgical return visit rate of 2.1%. During the study, 34 patients returned to the ED for a neurosurgical reevaluation. Patients returned for a neurosurgical reevaluation at a median of 23.5 days after the initial neurosurgery evaluation. The principal causes for a return visit were altered mental status, headache, and wound infections. Among the returning patients, 59% required hospitalization and 50% required an operation.

CONCLUSIONS

To our knowledge, this is the first study to prospectively collect data to estimate the 90-day ED return visit rate for a neurosurgical reevaluation following an initial ED neurosurgical evaluation. Some patients still use the ED to get continued care of their condition despite having access to their primary care physician. Better communication, social worker coordination, and prompt follow-up appointments at the neurosurgical outpatient clinic may reduce return visits.

Abdominal Pain in the Emergency Department: Missed Diagnoses

Abdominal pain is the most common chief complaint in the Emergency Department. Abdominal pain is caused by a variety of gastrointestinal and nongastrointestinal disorders. Some frequently missed conditions include biliary pathology, appendicitis, diverticulitis, and urogenital pathology. The Emergency Medicine clinician must consider all aspects of the patient's presentation including history, physical examination, laboratory testing, and imaging. If no diagnosis is identified, close reassessment of pain, vital signs, and physical examination are necessary to ensure safe discharge. Strict verbal and written return precautions should be provided to the patient.
