-
Modified Braden Scale score of 14 or less. The Modified Braden Scale score is calculated as follows:
Braden Scale score (Ranges from 6 to 23)
- 1 for Low Serum Albumin
- 1 for Type II Diabetes
-
Anticipated length of stay of at least 4 days
-
BMI < 35
-
Participants capable of giving informed consent, or if appropriate, participants having an acceptable individual capable of giving consent on the participant's behalf.
- Existing pressure injuries above Stage II and injuries classified as DTI or unstageable
- Neuromuscular blocking drugs & myasthenia gravis: may prevent the ability of electrical stimulation to induce muscular contraction
- Unstable spinal, pelvic, or hip fractures that may be displaced by a forced contraction
- Rhabdomyolysis
- Use of a Pacemaker
- Skin breakdown over the gluteal regions that would preclude the use of surface electrodes.

Group Intervention Description Standard of Care Standard of Care Therapy Standard of care treatment for pressure injuries is turning the patient every two hours. IES Device + Standard of Care IES System Intermittent electrical stimulation system. Charged pulses will be administered to bilateral gluteus maximus through surface electrodes. Stimulation occurs at 30 Hz for 10s every 10 minutes. The intervention is administered 24/7 and added to the standard of care management. Standard of care is defined as turning the patient every two hours. IES Device + Standard of Care Standard of Care Therapy Intermittent electrical stimulation system.

- Primary Outcome Measures
Name Time Method Clinical course of pressure injury over time Patients will be assessed daily for pressure injury location and stage through treatment completion, an average of 14 days. Chauhan Weighted Trajectory Analysis (CWTA) will be used to compare the morbidity associated with sacral and ischial pressure injuries through time. A one-sided Chauhan logrank test at a significance of 0.05 will be used to assess for superiority of the experimental arm over the control arm.
- Secondary Outcome Measures
Name Time Method Cox Regression Analysis Final analysis will be performed at end of study (expected completion 2 years) Cox-regression analysis will be used to determine whether the implementation of the IES device is associated with a significant difference in sacral and ischial pressure injury time-to-event occurrence between treatment groups.
Relative Risk Final analysis will be performed at end of study (expected completion 2 years) Relative risk of sacral and ischial pressure injuries will be compared between treatment groups using a 2x2 contingency table with a 95% confidence interval.
Clinical course of pressure injury in subgroups Patients will be assessed daily for pressure injury location and stage through treatment completion, an average of 14 days. Chauhan Weighted Trajectory Analysis (CWTA) will be used to compare the morbidity associated with sacral and ischial pressure injuries through time. A one-sided Chauhan logrank test at a significance of 0.05 will be used to assess superiority.
Kaplan-Meier Time-to-Event Analysis Final analysis will be performed at end of study (expected completion 2 years) A Kaplan Meier Curve and logrank Test (one-sided significance at p \< 0.05) will be used to evaluate a difference in sacral and ischial pressure injury time-to-event morbidity between groups. An "event" is defined as the development of any stage/class of pressure ulcer.
Description of adverse events related to IES Final analysis will be performed at end of study (expected completion 2 years) We will report frequency and severity of skin changes underlying the electrodes, categorized as i) transient erythema after electrode removal, ii) non-transient skin changes after electrode removal, iii) skin breakdown under electrode.
Observed Counts of Pressure Injuries Final analysis will be performed at end of study (expected completion 2 years) Descriptive statistics and Chi-square testing will be used to compare in incidence rates and proportion between the treatment groups for sacral and ischial pressure injuries classified as Stage I-IV or Unstageable
Onset Time Final analysis will be performed at end of study (expected completion 2 years) Descriptive statistics will be used to report the central tendency and spread of the onset time of a sacral and ischial pressure injury for both treatment groups and for injuries classified as Stage I-IV or Unstageable
Duration of Inpatient Stay Final analysis will be performed at end of study (expected completion 2 years) Descriptive statistics will be used to report the central tendency and spread of the duration of inpatient stay for both treatment groups
