Pressure Injury and Spinal Cord Injury

More than 85% of people with SCI and SB will develop a pressure injury (PI) in their lifetime. At any one time, more than 30% of people with SCI and SB in Australia have a pressure injury. The prevalence rate in adults with SB is estimated to be 34%26. The social and economic impact of PI on the individual, family and community is immense and can have long term physical and psychological consequences.

SCI and SB-specific factors amplify risk

SCI and SB-specific risk factors increase exposure to extra pressure or reduce the skin’s ability to tolerate pressure.

Pressure Injury Risk
Tissue Tolerance
Impaired Mobility
Impaired Activity
Impaired Sensory Perception

Pressure

As a result of a SCI or SB, people are more susceptible to the effects of direct pressure due to: (i) impaired or absent protective sensation below the level of injury (e.g. loss of pain, temperature, pressure and light touch sensation), (ii) muscle paralysis which limits mobility, ability to transfer and re-distribute body weight, often requiring a wheelchair or assistive device and, as a result, (iii) significant limitations to functional activity.

Extrinsic Factors

Extrinsic factors reducing tissue tolerance for people with SCI or SB include: (i) increased moisture from hyperhidrosis, long periods of sitting or from possible bladder or bowel incontinence; (ii) friction from reduced clearance during transfers, poorly fitting equipment or clothing; and (iii) shear from sliding down the bed, reduced lift or clearance when re-positioning, muscle spasticity or sliding forwards in a poorly set-up wheelchair.

  • Moisture
  • Friction
  • Shear

Intrinsic Factors

Intrinsic factors reducing tissue tolerance for people with SCI or SB include: (i) impaired circulation from autonomic nervous system and cardiovascular changes, and, decreased muscle pump reducing venous return and the delivery of oxygen to the muscles; (ii) use of medications that reduce alertness; (iii) increased risk of malnutrition; (iv) high prevalence of comorbidities and other chronic diseases; and (v) secondary conditions such as shoulder pain reducing the ability to lift and transfer body weight during daily mobility and self-care activities.

  • Demographics
  • Nutrition
  • Chronic illness
  • Pain
  • Skin
  • Temperature

Braden & Bergstrom (1987)

Psychosocial and lifestyle factors contribute significantly to PI development and the success of the management plan.

Lifestyle factors

This table23 can be used by health professionals and consumers to explain pressure injury development and target risk factors. Information is based on results from the University of Southern California (USC) and Rancho Los Amigos National Rehabilitation Center (RLANRC)’s Lifestyle Redesign® for Pressure Ulcer Prevention in Spinal Cord Injury project.

FACTOREXPLANATION
Perpetual danger Even when an individual implements preventive strategies, unforeseen circumstances may trigger pressure ulcer development.
Change or disruption of routine Development of a pressure ulcer may sometimes be traced to a single change that disrupts the existing risk equilibrium and produces a cascade of events.
Decay of prevention behaviours Distractions, forgetfulness, and other factors may reduce the frequency of performing prevention techniques, often without the individual even recognising it.
Lifestyle risk ratio This is the impact of the sum of physical or lifestyle liabilities, such as poor nutrition and inadequate finances, and buffers, such as a good support system and adherence to preventive strategies.
Individualisation The unique balance of risk and prevention factors at any given time for each person with spinal cord injury determines pressure ulcer development.
Simultaneous presence of prevention awareness and motivation Long-term prevention knowledge, short-term attention to the situation, and adequate motivation to perform the strategies must all be present to prevent pressure ulcer development.
Lifestyle trade-off The ways in which an individual balances the needs to engage in personally meaningful activities and to use rest and caution to prevent pressure ulcers change the risk balance.
Access to needed care, service, and supports The inability to obtain appropriate services, for various reasons, at the time they would be most beneficial or necessary increases pressure ulcer risk.

Assessment of ongoing pressure injury risk

Use the results of a comprehensive and systematic assessment of pressure ulcer risk factors to select and implement risk management strategies in individuals with spinal cord injury.20

All people with SCI and SB are at high risk of developing pressure injuries. There is no SCI and SB -specific PI risk assessment that has demonstrated reliability with this population. Currently the Braden Scale or the Waterlow Scale are most commonly used.

Braden Scale and the Waterlow Scale

All people with SCI and SB are at high risk of developing pressure injuries. Until a reliable and consistent SCI and SB -Specific pressure injury risk assessment is developed the Braden Scale or the Waterlow Scale is recommended.

Clark et al (2006) 9 describe a person’s risk profile in terms of interacting physical, mechanical, health-behaviour, psychological, social and environmental liabilities and buffers.

Risk stratification may be useful prior to a comprehensive assessment of cause and contributing factors.

Risk stratification

PERSONAL AND ENVIRONMENTAL CHARACTERISTICS

Risk may be further stratified based on a range of factors.



Protective Factors High Risk Most at Risk
  • Employed
  • Good pressure relieving routines
  • Completion of secondary or tertiary education
  • Social supports in place
  • Self-management / Health maintenance skills
  • High self-efficacy
  • Strong problem solving skills
  • Good adjustment to injury, coping skills, resilience
  • Within a health weight range
  • Past history of pressure injury (Stage 1, 2)
  • Smoking
  • 1 comorbidity
  • Infrequent incontinence (urinary/faecal)
  • Ageing or older when injured

  • Overweight or recent weight gain
  • Postural asymmetry (trunk, pelvis +/- mild contracture)
  • Increased number of complex transfers (e.g. car, commode)

  • ≥ 2 comorbidities
  • Frequent incontinence (urinary/faecal)
  • Recent trauma, fall or fracture
  • Severe mental health disorder

  • Isolation and reduced social support
  • Malnutrition
  • Obesity
  • Marked postural deformity / severe contractures of pelvis / hips
  • Musculoskeletal upper limb injury affecting transfer quality and ability to pressure relieve
  • Damaged, inappropriate or no equipment
  • Onset of new or acute illness, or significant change in social circumstances or daily routine

Children with SCI and SB

Children with SCI and SB will develop PIs due to the nature of development and participation in activity during childhood and adolescence. It is important to identify and mitigate risks and prevent a minor PI from developing into a more significant PI or chronic wound.

Additional risk factors include:

  • Playing and moving around on the ground between hard surfaces, such as concrete, gravel, rocks, rubber playground flooring, plastic playground equipment, and in sandpits.
  • Insect bites from playing on the ground, heat burn from sliding on play equipment, ingrown toenails.
  • Transferring and sitting on plastic classroom chairs, the classroom floor, school toilet seats and playground seats.
  • Quickly outgrowing equipment such as wheelchairs, cushions, backrests, postural supports, commodes, TLSO braces and footwear (and allowing for the period of time required to prescribe and order equipment).
  • Scoliosis and additional postural changes such as pelvic obliquity and hip dislocation impacting on positioning and functional mobility.
  • Limited insight into changing pressure injury risk for families and children who may receive little ongoing information about the implications of impaired sensation as they grow. They may demonstrate complacency with pressure management and routines to prevent pressure injury.
  • Not having the necessary information, skills or motivation to self manage PI risk with growing independence as an adolescent or young adult.
  • Exposure to risks as a normal part of growth and development during childhood and adolescence.

The Braden Q or the Glamorgan Paediatric Pressure Ulcer Risk Assessment Scale may be used in a paediatric population.

Spina Bifida

  • Children and adults with SB and hydrocephalus experience executive dysfunction with difficulty in organising, planning, initiating, problem-solving and dealing with novel tasks. 47 p.1
  • The Risk Stratification above may also be useful in determining risk for people with SB .
