Health mediation does not reduce the readmission rate of frequent users of emergency departments living in precarious conditions: what lessons can be learned from this randomised controlled trial?

BACKGROUND

Severe overcrowding of emergency departments (EDs) affects the quality of healthcare. One factor of overcrowding is precariousness, but it has rarely been considered a key factor in designing interventions to improve ED care. Health mediation (HM) aims to facilitate access to rights, prevention, and care for the most vulnerable persons and to raise awareness among healthcare providers about obstacles in accessing healthcare. The primary aim was to determine whether HM intervention for frequent users of EDs (FUED) living in precarious conditions could reduce the readmission rate at 90 days.

METHODS

Between February 2019 and May 2022, we enrolled and interviewed 726 FUED in four EDs of southeastern France in this randomised controlled trial. The HM intervention started in the ED and lasted 90 days. In addition to the primary endpoint (first readmission at 90 days), secondary endpoints (readmission at 30 and 180 days, number of hospitalisations at 30, 90, 180 days, admissions for the same reasons as the first admission) were also studied. The outcomes were measured in the ED information systems. Statistical methods included an intention-to-treat analysis and a per-protocol analysis. Comparisons were adjusted for gender, age, ED, and health mediator.

RESULTS

46% of patients reported attending the ED because they felt their life was in danger, and 42% had been referred to the ED by the emergency medical dispatch centre or their GP; 40% of patients were considered to be in a serious condition by ED physicians. The proportion of patients who were readmitted at 90 days was high but did not differ between the control and the HM intervention groups (31.7% vs. 36.3%, p = 0.23). There was no significant difference in any of the secondary outcome measures between the control and HM intervention groups. Per-protocol analysis also showed no significant difference for the primary and secondary endpoints.

CONCLUSIONS

This randomised controlled trial did not show that our health mediation intervention was effective in reducing the use of emergency services by FUED living in precarious conditions. Some limitations are discussed: the duration of the intervention (90 days), the long-term effects (> 6 months), the involvement of the ED staff.

Use of Care Guides to Reduce Emergency Department Visits by High-Frequency Utilizers

BACKGROUND

High-frequency utilizers are defined as patients who present 10 or more times to the emergency department in a rolling 12-month period. High-frequency utilizers contribute to emergency department overcrowding and misuse of resources, and reduce the efficiency of health care systems. Care guides have proven to be an effective tool in reducing high-frequency utilizers.

OBJECTIVE

The objective of this quality improvement project was to determine if implementing a care guide for high-frequency utilizers to address the core needs of the patient and facilitate resources through case management consultation decreases the number of visits and the cost of unreimbursed care to the emergency department from high-frequency utilizers.

METHODS

We implemented care guides for high-frequency utilizers in September 2014. Prior to initiating the care guides, we educated the physicians, nurses, case managers, and social workers in the emergency department.

RESULTS

Following the implementation of the care guides, there was a steady decline in the number of high-frequency utilizers (338 in 2013-68 in 2021), the number of total emergency department visits by high-frequency utilizers (6025 in 2013-1033 in 2021), and unreimbursed care ($2,068,063 in 2013-$589,298 in 2021).

CONCLUSION

The use of care guides was a successful strategy in reducing emergency department visits and the cost of unreimbursed care by high-frequency utilizers by providing them with the education and resources they require to receive health care services in appropriate settings.

Social and demographic characteristics of frequent or high-charge emergency department users: A quantile regression application

OBJECTIVE

Heavy users of the emergency department (ED) are a heterogeneous population. Few studies have captured the social and demographic complexity of patients with the largest burden of ED use. Our objective was to model associations between social and demographic patient characteristics and quantiles of the distributions of ED use, defined as frequent and high-charge.

METHODS

We conducted a cross-sectional analysis of electronic health and billing records of 99 637 adults residing in an urban North Carolina county who visited an ED within Atrium Health, a large integrated health care system, in 2017. Mid-quantile and standard quantile regression models were used for count and continuous responses, respectively. Frequent and high-charge use outcomes were defined as the median (0.50) and upper quantiles (0.75, 0.95, 0.99) of the outcome distributions for total billed ED visits and associated charges during the study period. Patient characteristic predictors were: insurance coverage (Medicaid, Medicare, private, uninsured), total visits to ambulatory care during the study period (0, 1, >1), and patient demographics: age, gender, race, ethnicity, and living in an underprivileged community called a public health priority area (PHPA).

RESULTS

Results showed heterogeneous relationships that were stronger at higher quantiles. Having Medicaid or Medicare insurance was positively associated with ED visits and ED charges at most quantiles. Racial and geographic disparities were observed. Black patients had more ED visits and lower ED charges than their White counterparts at most quantiles of the outcome distributions. Patients living in PHPAs, had lower charges than their counterparts at the median but higher charges at the 0.95 and 0.99 quantiles.

CONCLUSIONS

The relationships between patient characteristics and frequent and high-charge use of the ED vary based on the level of use. These findings can be used to inform targeted interventions, tailored policy, and population health management initiatives.

After COVID-19: Improving the Patient's Outpatient Appointment Experience

As the COVID-19 pandemic diminishes, it is expected that patients will seek more outpatient appointments resulting in adverse patient and clinic experiences if there is a corresponding increase in missed appointments. This study's purpose was to determine if there was an association between advanced access scheduling, also known as open access or same day scheduling, and missed appointment rates for patients scheduled with preferred primary care physicians vis-a-vis nonpreferred primary care physicians. Patients prescheduled with primary care providers and over the age of 18 years were included in the study, which totaled 4815 visits. Study results demonstrated a statistically significant mean proportion difference between the national no-show rate and the study's no-show rate as well as a significant association between physician type and visit status. The results suggested the potential for improving the patient experience with advanced access scheduling if patients are scheduled with their preferred primary care physician. This study may promote positive patient experiences by providing patients and clinicians with an understanding of the significance surrounding advanced access scheduling thus decreasing missed appointments.
