State of the Union: Timeliness to Antibiotics in Open Fractures

Impact of 24-hour pharmacy call response on time to antibiotics in open fractures

PURPOSE

Open fractures are associated with significant morbidity after trauma, which is driven, in part, by infection. Current literature and guidelines recommend that this patient population receive antimicrobial prophylaxis within 1 hour of emergency department (ED) arrival to minimize the risk of infection. The primary aim of this study was to investigate whether the addition of a trauma response to a pharmacy resident on-call program resulted in antibiotic administration within 1 hour of presentation to a higher proportion of patients with open fractures.

METHODS

This was a retrospective, observational, quasi-experimental analysis that was conducted at an academic medical facility with a level 1 trauma center for patients presenting to the ED from January 2019 to December 2020 (preimplementation period) and from January 2021 to December 2022 (postimplementation period). Patients were included if they were 18 years of age or older and presented to the ED with an open fracture(s). Patients with independent fractures of fingers and those who died in route to or in the ED were excluded. The primary outcome was the proportion of patients with antibiotic administration within 1 hour of ED presentation for patients with open extremity fractures.

RESULTS

A total of 292 patients met the eligibility criteria (49% in the preimplementation group and 51% in the postimplementation group). Patients were predominantly male (61% vs 58%), with an overall median age of 46 years. Following implementation of the on-call pharmacy resident trauma response, a significantly higher proportion of patients received antibiotics within 1 hour of presentation (70% vs 83%; P = 0.019). The median (interquartile range) time to antimicrobial administration was also significantly shorter in the postimplementation group (31 [16-68] minutes vs 19 [10-50] minutes; P = 0.005).

CONCLUSION

The addition of a 24-hour on-call pharmacy resident response in the ED was associated with improved antibiotic administration within 1 hour of presentation in patients with open fractures.

Prehospital Antibiotic Administration for Suspected Open Fractures: Joint COT/OTA/ACEP/NAEMSP/NAEMT Position Statement

One of the primary concerns associated with open fractures is the development of a fracture-related infection (FRI). To minimize the risk of developing an FRI and subsequent morbidity, prophylactic antibiotics should be administered to patients with open fractures as soon as possible. While the antibiotic recommendations for severe open fractures are somewhat debatable, the use of a cephalosporin remains a mainstay of prophylactic treatment. Though administration of prehospital antibiotics does represent an expansion of EMS responsibilities, there have been several other treatment expansions in the prehospital setting, such as the administration of tranexamic acid and the application of pelvic binders. The administration of antibiotics, specifically cefazolin, is inexpensive, technically simple, and does not require special storage. The following recommendations are supported by and represent consensus of the COT, OTA, ACEP, NAEMSP and NAEMT with regards to prehospital antibiotic prophylaxis for suspected fractures: In a responsive patient with no history of penicillin or cephalosporin allergy, the administration by EMS of a 1st generation cephalosporin should be performed after the management of life threats. This intervention should not delay transport.In an obtunded patient, the administration by EMS of a 1st generation cephalosporin should be performed after the management of life-threats. This intervention should not delay transport.In a responsive patient with a documented penicillin allergy, the administration by EMS of a 1st generation cephalosporin should be performed with close monitoring after the management of life-threats. This intervention should not delay transport.

Implementation of a Trauma Bay Checklist Improves Antibiotic Prophylaxis Compliance in Open Extremity Fractures

BACKGROUND

Best practice guidelines from the ACS recommend that patients with open fractures receive antibiotics within 1-hour of presentation. Checklists are effective mechanisms for improving safety and compliance in surgical settings. The current study investigates implementation of a trauma bay checklist, referred to as MARTY, to improve administration of antibiotics in open extremity fractures at a level I trauma center.

METHODS

Retrospective pre-post design. Population consisted of trauma alerts from January to December 2021 (pre-MARTY) and 2022 (post-MARTY) with open fractures. Outcome measures included antibiotics administered within 1-hour of presentation and in the trauma bay. Bivariate and multivariate analyses were performed to estimate differences in both measures.

RESULTS

Our sample included 339 encounters, 174 pre-MARTY and 165 post-MARTY implementation. In the pre-MARTY period, 57.5% of encounters received antibiotics within 1-hour of presentation with 46.0% occurring in the trauma bay, in comparison to 65.5% and 54.5% in the post-MARTY period. In adjusted models, there were greater odds of antibiotic administration within 1-hour (OR = 1.654, P = .038) and prior to leaving the trauma bay (OR = 1.660, P = .041) than pre-MARTY. Encounters with higher-grade fractures were more likely to receive timely antibiotics (P<=.001).

DISCUSSION

Our study estimates improved compliance of antibiotic administration after implementation of MARTY after adjusting for encounter characteristics. Findings from this study demonstrate improved compliance, but this compliance is often still lacking in those with higher injury severity scores. Findings from this study may be used to inform approaches to further improve trauma care.

Factors affecting early antibiotic delivery in open tibial shaft fractures

INTRODUCTION

The incidence of infection in open tibial shaft injuries varies with the severity of the injury with rates ranging from roughly 2% for Gustilo-Anderson type I to nearly 43% for type IIIB fractures. As with all fractures, timely antibiotics administration in the emergency department (ED) is an essential component of fracture management and infection prevention. This study identifies factors associated with the expedient administration of antibiotics for open tibial shaft fractures.

METHODS

This retrospective study identified patients treated for open tibial shaft fractures at an academic level 1 trauma center between 2015 and 2021. Open fractures were identified by reviewing patient charts. We used chart reviews to gather demographics, fracture characteristics, postoperative outcomes, trauma activation, and time to antibiotic order, delivery, and operating room. Univariate analysis was used to compare patients who received antibiotics within 1 h of ED presentation to those who did not. Multivariate analysis was performed to investigate factors associated with faster delivery of antibiotics.

RESULTS

Among 70 ED patients with open tibial shaft fractures, 39 (56%) received early administration of antibiotics. Arrival at the ED via emergency medical service (EMS) as opposed to walking in (98% vs. 74%, p = 0.01) and trauma activation (90% vs. 52%, p < 0.001) were significantly more common in the early administration group than the late group. The early group had shorter intervals between antibiotic order and delivery (0.02 h vs. 0.35 h, p = 0.007). Multivariate analysis suggested that trauma activation, EMS arrival, and arrival during non-overnight shifts were independent predictors of a shorter time to antibiotic administration (odds ratios 11.9, 30.7, and 5.4, p = 0.001, 0.016, and 0.013, respectively).

DISCUSSION

Earlier antibiotic delivery is associated with non-overnight arrival at the ED, arrival via EMS, and a coordinated trauma activation. Our findings indicate that in cases where administering antibiotics is critical to achieving positive outcomes, it is advisable to initiate a coordinated trauma response. Furthermore, hospital personnel should be attentive to the need for rapid administration of antibiotics to patients with open fractures who arrive via walk-in or during late-night hours.

Contemporary management of open extremity fractures: What you need to know

ABSTRACT

Open extremity fractures are high-risk injuries prone to significant complications, including soft tissue loss, bone defects, infection, infected nonunion, and the necessity for limb amputation. Large-scale multicenter prospective studies from the Lower Extremity Assessment Project and the Major Extremity Trauma Research Consortium have provided novel scientific insights pertinent to the timeliness and appropriateness of specific treatment modalities aimed at improving outcomes of patients with open extremity injuries. These include the imperative for early administration of intravenous antibiotics within 3 hours of injury, preferably within 1 hour of hospital admission. Unlike the proven value of early antibiotics, the time to initial surgical debridement does not appear to affect infection rates and patient outcomes. Recent evidence-based consensus guidelines from the American Academy of Orthopedic Surgeons provide scientific guidance for preventing surgical site infections in patients with open extremity fractures and support the decision making of limb salvage versus amputation in critical open extremity injuries. Patient survival represents the overarching priority in the management of any trauma patient with associated orthopedic injuries. Therefore, the timing and modality of managing open fractures must take into account the patient's physiology, response to resuscitation, and overall injury burden. The present review was designed to provide a state-of-the-art overview on the recommended diagnostic workup and management strategies for patients with open extremity fractures, based on the current scientific evidence.

Time Savings and Safety of EMS Administration of Antibiotics for Open Fractures

INTRODUCTION

Early administration of antibiotics for open fractures reduces serious bone and soft tissue infections. The effectiveness of antibiotics in reducing these infections is time-dependent, with various surgical associations recommending administration within one hour of injury, or within one hour of patient arrival to the emergency department (ED). The extent to which prehospital antibiotic administration in these situations might reduce the time to treatment has not been previously reported. The purpose of this study was to describe current prehospital use of antibiotics for traumatic injury, to assess the safety of prehospital antibiotic administration, and to estimate the potential time-savings associated with antibiotic administration by EMS clinicians.

METHODS

This was a retrospective analysis of the 2019 through 2022 ESO Data Collaborative research data set. Included subjects were patients that had a linked ICD-10 code indicating an open extremity fracture and who received prehospital antibiotics. Time to antibiotic administration was calculated as the elapsed time from EMS dispatch until antibiotic administration. The minimum potential time saved by EMS antibiotic administration was calculated as the elapsed time from administration until ED arrival. To assess safety, epinephrine and diphenhydramine administration were used as proxies for the adverse events of anaphylaxis and minor allergic reactions.

RESULTS

There were 523 patients meeting the inclusion criteria. The median (and interquartile range [IQR]) elapsed time from EMS dispatch until antibiotic administration was 31 (IQR: 24-41) minutes. The median potential time savings associated with prehospital antibiotic administration was 15 (IQR: 8-22) minutes. Notably, 144 (27.5%) of the patients who received prehospital antibiotics had total prehospital times exceeding one hour. None of the patients who received antibiotics also received epinephrine for presumed anaphylaxis.

CONCLUSIONS

EMS clinicians were able to safely administer antibiotics to patients with open fractures a median of 15 min before arrival at the hospital, and 99% of the patients receiving antibiotics had them administered within one hour of EMS dispatch. EMS administration of antibiotics may be a safe way to increase compliance with recommendations for early antibiotic administration for open fractures.

Nurse-Initiated Protocol to Improve Timely Antibiotic Administration in Pediatric Open Fractures

BACKGROUND

Early administration of antibiotics in the presence of open fractures is critical in reducing infections and later complications. Current guidelines recommend administering antibiotics within 60 min of patient arrival to the emergency department, yet trauma centers often struggle to meet this metric.

OBJECTIVES

This study aims to evaluate the impact of a nurse-initiated evidence-based treatment protocol on the timeliness of antibiotic administration in pediatric patients with open fractures.

METHODS

A retrospective pre-post study of patients who met the National Trauma Data Standard registry inclusion criteria for open fractures of long bones, amputations, or lawn mower injuries was performed at a Midwestern United States Level II pediatric trauma center. The time of patient arrival and time of antibiotic administration from preimplementation (2015-2020) to postimplementation (2021-2022) of the protocol were compared. Patients transferred in who received antibiotics at an outside facility were excluded.

RESULTS

A total of N = 73 participants met the study inclusion criteria, of which n = 41 were in the preimplementation group and n = 32 were in the postimplementation group. Patients receiving antibiotics within 60 min of arrival increased from n = 24/41 (58.5%) preimplementation to n = 26/32 (84.4%) postimplementation (p< .05).

CONCLUSIONS

Our study demonstrates that initiating evidence-based treatment orders from triage helped decrease the time from arrival to time of antibiotic administration in patients with open fractures. We sustained improvement for 24 months after the implementation of our intervention.
