The Effect of Histopathologic Analysis and Tissue Cultures on Inpatient Management of Cellulitis and Pseudocellulitis

March 20, 2025 updated by: Ben H Kaffenberger, Ohio State University
The Investigators wish to study the value of dermatologic testing assessments in differentiating between cellulitis and pseudocellulitis in the inpatient setting. The Investigators propose that by utilizing cutaneous biopsies and tissue cultures in patients that have been admitted to inpatient internal medicine teams, the investigators may be able to improve multiple measures of hospital efficiency in patients presenting with cellulitis-like symptoms, by more accurately recognizing cellulitis from pseudocellulitis. The patient will undergo encrypted digital imaging for his or her condition. This image will then be sent to the study investigators, along with basic clinical information on the skin evaluation form. The study investigators will develop a differential diagnosis and then the patient will undergo a skin biopsy. The patient will then be randomized to one of two arms using a random number generator: A) Skin biopsies and tissue cultures recorded and published in patient's medical chart as they would be in a standard of care procedure B) Skin biopsies and tissue cultures consultation performed but not published in the patient's medical chart unless medically necessary. Information will be collected from medical records in IHIS. Patients will be contacted by phone 30 days after discharge.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 99 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Patient's ages 18 to 99 years that present in the ED with pseudocellulitis or cellulitis.

Description

Inclusion Criteria:

  • admitted inpatient to The Ohio State University Wexner Medical Center Internal Medicine ward with cellulitis-like symptoms, including but not limited to the following: tenderness, redness, swelling, expansive lesion.
  • Affecting one or more extremities
  • are at least 90 days post any associated operation of the extremity
  • are above the age of 18
  • Participants will be patients with cellulitis or pseudocellulitis.
  • Patients who have recurrent cellulitis will be eligible for enrollment into the study, but only once.

Exclusion Criteria:

  • Patients who are pregnant
  • Prisoners
  • Patients may not have trauma, ulcer, or puncture wound to the area
  • May not be transferred from another hospital
  • May not be admitted to the Cancer Hospital or with a known active solid organ or hematologic cancer other than nonmelanoma skin cancer

Design Details

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The feasibility of conducting a larger study will be conducted, by establishing patient enrollment rates
Time Frame: At study completion, around 2 years after study start
According to the NIH: The goal of pilot work is not to test hypotheses about the effects of an intervention, but rather, to assess the feasibility/acceptability of an approach to be used in a larger scale study. We will use descriptive statistics to monitor patient enrollment and pilot data on additional secondary outcomes for inferential statistics.
At study completion, around 2 years after study start

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in antibiotic use (antibiotics/day administered) over the course of the hospitalizations
Time Frame: 1 year
Cellulitis is a common type of bacterial skin infection. Pseudocellulitis is a skin infection that is very similar to cellulitis and is often misdiagnosed as cellulitis
1 year
The rate of participant readmission within 30 days
Time Frame: 1 year
The investigators will examine 30 day readmission rates between standard care and interventional care
1 year
Length of hospitalization as measured in days
Time Frame: 1 year
The investigators will examine hospital length-of-stay in patients randomized to interventional vs standard care
1 year

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
May 25, 2018

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
