ALS vs BLS: EMS System Structures and Tiered Care
This paper examines the structure and effectiveness of emergency medical services (EMS) systems, focusing on how advanced life support (ALS) professionals are deployed across different models. It outlines the roles of paramedics, critical care paramedics, and emergency care practitioners within single-tier ALS systems, such as those used in Portland and Washington County. The paper then contrasts these with two-tiered systems that incorporate basic life support (BLS) units, illustrating operational and financial challenges using a New Jersey case example. The analysis concludes that single-tier ALS systems may offer greater efficiency, cost-effectiveness, and quality of patient care in many contexts.

What makes this paper effective
- Clearly defines each ALS professional role before moving into comparative analysis, giving readers the conceptual grounding needed to evaluate the arguments that follow.
- Uses a concrete real-world example (New Jersey's two-tiered system) to illustrate abstract operational and financial inefficiencies, making the argument tangible and credible.
- Maintains a measured, evidence-acknowledging tone by noting that the superiority of all-ALS systems has not been conclusively established in research, which strengthens academic integrity.
Key academic technique demonstrated
This paper demonstrates comparative analysis grounded in applied examples. Rather than arguing from theory alone, it anchors each claim about system design in observable operational realities — such as ALS crews arriving in separate Ford Explorers with no transport capability — to show how structural choices produce tangible consequences for cost and care quality.
Structure breakdown
The paper opens by introducing EMS system models and defining the three ALS professional types. It then shifts to two-tiered and multi-tiered alternatives, describing how dispatch protocols and staffing arrangements differ. The final section weighs financial and operational trade-offs before offering a reasoned conclusion favoring single-tier ALS systems. The structure follows a definition-then-comparison pattern well suited to short analytical papers at the undergraduate level.
Introduction to EMS System Models
There are many different emergency medical services (EMS) systems that utilize advanced life support (ALS) professionals in different ways. Some EMS systems place an ALS professional on all first-response units, as seen in Portland and Washington County. The ALS group is a team of highly trained individuals who provide advanced medical care to patients in transit; their training exceeds that of a standard EMT.
ALS Professionals and Their Roles
Generally, ALS teams are composed of three types of professionals (FCEMS, N.d.):
Paramedic (EMT-P) — Paramedics are licensed individuals who can perform tasks beyond those of an EMT. These tasks include cardiac monitoring, intubation, and administering intravenous medications.
Critical Care Paramedic (CCEMTP) — Critical care paramedics are similar to standard paramedics but are certified to provide a higher level of care to patients in critical conditions. Through their specialized training, they are authorized to operate sensitive equipment typically found only in intensive care units (ICUs), and to perform procedures such as blood administration and chest tube insertion, among others.
Emergency Care Practitioner (ECP) — ECPs are paramedics who have obtained special certifications to conduct expanded clinical practices.
Although the all-ALS concept intuitively appears to provide a higher level of care in emergency situations, this has not been conclusively established in the research literature.
