Official title: Anxiety Surrounding Supracondylar Pin Removal in Children: A Randomized Controlled Trial

Status Not yet recruiting

Clinical Trial Summary

This study aims to determine if removing supracondylar pins immediately following cast removal and prior to X-ray decreases patient and parent/guardian anxiety compared to pin removal following cast removal and X-ray. The research team hypothesizes that patient anxiety response will be lower when pins are removed immediately following cast removal compared to our current standard of care. Secondarily, this study will determine if there is an association between patient anxiety response and their parent's/guardian's anxiety.

Clinical Trial Description

Supracondylar humerus (SCH) fractures are one of the most common pediatric injuries. These fractures are reported as the second most common pediatric fracture, constituting about 18% of all pediatric fractures and approximately 60% of all elbow fractures. The median age of injury is between 3 and 8 years old, peaking at 5 to 6 years old. The gold standard for treating displaced SCH fractures is closed reduction and percutaneous pinning (CRPP); pins are almost always removed three to four weeks post-surgery in outpatient clinics, without anesthesia.

Many would assume that patients experience anxiety during pin removal, but no studies to our knowledge quantified a patient's physiological and behavioral response during this procedure. However, there have been many in-depth investigations of these responses during cast removal procedures, where heart rate (HR) is used as a psychological indicator of anxiety. Additionally, Merkel et al. developed the Face, Legs, Activity, Cry and Consolability (FLACC) Scale which is a valid and reliable tool to quantify pain behaviors in children. Further research showed that the FLACC Scale was also sensitive to painless procedures (i.e. intravenous insertion), and therefore, it can be considered a composite of pain and distress (anxiety).

Anxiety in the medical setting has been linked to future adverse effects for children. Previous publications have shown that patients with anxiety in the perioperative setting have increased postoperative pain, maladaptive behavior, and long-term anxiety with future medical visits. Preoperative anxiety in children also has been reported to have similar negative effects on behavior. It is plausible that an anxiety-provoking procedure, such as pin removal, would have similar effects.

The primary purpose of the first phase of this study (IRB-P00028933), which took place from 2018 to 2020, was to quantify the anxiety experienced by patients undergoing pin removal in clinic following closed reduction and percutaneous pinning (CRPP) for SCH fractures. Now that the first phase is complete, the research team is interested in taking this research another step forward to see how healthcare providers can reduce patient and parent anxiety in clinical settings. Before the first phase of this study, there were no known studies that quantified a patient's physiological and behavioral response during a postoperative pin removal procedure, as CRPP is the gold standard treatment for displaced supracondylar humerus (SCH) fractures. The findings of the primary purpose of the first phase ultimately demonstrated that all patients undergoing pin removal experience an anxiety response, therefore highlighting an area of clinical practice in need of a targeted to help decrease patient anxiety and improve patient experience.

Patients currently proceed with the following clinical flow on the day of their pin removal:

(1) patients first present to the cast room for cast removal, (2) radiographs are obtained to confirm alignment and fracture stability, and (3) patients are seen by their provider in an orthopaedic clinic room for pin removal. While this process is streamlined in a busy orthopaedic clinic, it could still take up to an hour of time. After cast removal may also be the first time a patient sees the pins and this added time before pin removal could escalate anxiety. It is evident in the literature that an X-ray prior to pin removal is unnecessary, as it does not change clinical management. Anxiety in the medical setting has been linked to future adverse effects for children, such as increased postoperative pain, maladaptive behavior, and long-term anxiety with future medical visits. It is plausible that an anxiety-provoking procedure, such as pin removal, could have similar effects. Ultimately, the findings of the first phase of our study provide the groundwork for future research efforts in techniques to minimize anxiety for the pediatric patient having to undergo pin removal. Something as simple as changing the clinic flow of our current pin removal process, such as removing pins immediately following cast removal and prior to X-ray, may decrease the overall time waiting for pin removal and decrease patient anxiety.

Therefore, the primary aim of this study is to determine if removing supracondylar pins immediately following cast removal and prior to X-ray decreases patient and parent/guardian anxiety compared to pin removal following cast removal and X-ray. It is hypothesized that patient anxiety response will be lower when pins are removed immediately following cast removal compared to our current standard of care. Secondarily, this study will aim to determine if there is an association between patient anxiety response and their parent's/guardian's anxiety.

After consenting to participate in the trial, patients will be randomized to one of two treatment arms--the intervention or the control-that will be evaluated for this study. We will measure patient and parent/guardian anxiety on the day of pin removal. We plan to randomize patients into two clinical flows: standard of care clinic flow (control treatment) and change in clinic flow (new treatment).

Control Group Patients in the control group will: 1. Go to cast room for cast removal, 2. Go to radiology for X-ray, 3. Will be seen in clinic room for pin removal. These steps are our current standard of care. An orthopedic, cast room technician bivalves and removes the top half of the patient's cast. In radiology, anteroposterior (AP) and lateral X-ray views are obtained to confirm radiographic healing. In the clinic room, a surgeon or nurse removes the pins using pin removal pliers.

Intervention Group Patients in the treatment group will: 1. Go to cast room for cast removal,

2. Have pins immediately pulled after cast removal, 3. Go to radiology for X-ray, 4. Will be seen in clinic room by provider

In both groups, the study coordinator will record FLACC score and HR for patients and STAIS-5 score for parents/guardian. Training to administer the FLACC will include discussion led by the PI (Yi-Meng Yen, MD, PhD) about the 5 categories, clarification of defining characteristics for behaviors, and scoring techniques. Additionally, the study coordinator has already been trained to administer the FLACC and can also teach other study coordinators. If multiple study coordinators are used to administer the FLACC, reliability will be assessed. ;
