Introduction

Introduction: For years, rising EMS call

volumes have taxed resources in EMS

jurisdictions. A significant problem of

utilization by frequent 911 callers has contributed to transports and ED utilization, some of which may be

unnecessary. Solutions to this have

been limited for field providers.

Setting: MCFRS

The Montgomery County Fire Rescue Service (MCFRS) is an all-hazard combination system that provides a tiered emergency medical service response and transport in urban/suburban/rural settings. MCFRS responds to 80,000 medical incidents and transports close to 65, 000 patients per year in a basic and advanced life support deployment model.

How busy are we?

Respond to ~ 100,000 EMS calls per year 60,210 BLS in 2015 38, 276 ALS in 2015

Call volume increases each year,

however our resources do not as much

Setting

Past Practice For Super Users pre-2015

Transport to Emergency Department Ad hoc referral to Adult Protective Services

No partnerships with other agencies (HHS)

Feedback/follow-up to field providers difficult

Super User Defined

Four (4) or more calls to 911 in any

30 day period for medical related assistance during study period

Purpose of Study

Purpose: To study the initial effect a new

EMS partnership with our County’s HHS that could intervene with services for 911 “Super-users”, with alternate option for patients besides EMS activation

Montgomery County Non-Emergency

Integrated Community Care Coordination

MC-NIC 3

Methodology

Study Design: Retrospective comparison of

transports before and after partnership

Identified the most frequent 911 users by

medical and dispatch records, and targeted them for partnership with MC-HHS

We retrospectively reviewed call volumes

before and after intervention

Used a new ePCR system for retrospective

14 month study of the scope of the problem that may be impacted by intervention.

Results

 Table 1: Data

 Results: The highest users (N=14) generating

128 calls in the quarter ending in March 2015 were referred to HHS, which enhanced services available to them. They were primarily vulnerable adults. In the Quarter after intervention, their cumulative call volume decreased to 47 (64%).

Results

In a second phase, we developed field

referral and e-PCR search programs to identify super-users over a 14 month period from April 2015 to July 2016. There were 265 patients with > 10 calls in study period accounting for 4,393 e-PCRs

Of those, the top super-users (N=20) accounted

for 797 responses.

Conclusions

 We showed that super users in our large system are

ften vulnerable adults.

 A partnership between MCFRS and MC-HHS had

preliminary impacts on call volumes generated by a cohort of the highest users

 A second phase identified the magnitude of EMS

patients this partnership might reach. This preliminary multi-phase partnership and its interventions show potential to stem growing EMS overutilization.

 More studies are needed to prospectively prove the

value and best practices of these programs.

Limitations



Retrospective review of only two sources of data, CAD and ePCR, and small numbers



Did not identify the percentages of calls for true emergencies versus low acuity



This study supports an association between changes entailed in the partnership and reduced call volumes but not a cause-and- effect relationship



Not every patient who is classified as super user sustains level of frequency, so may cease to be a super user with or without MC-HHS
