Surprise Surprise !!!!!! The Agency for Health Research and Quality
(AHRQ) recently released a survey showing a 63%increase in pressure ulcer occurrence in acute carehospitals from ```1993 to 2003 (Russo,2006)

In a review of 218 research articles (Lyder, 2002),
it was reported the cost of treatment to range from$500 to $40,000 per ulcer and that a singlehospital stay due to a pressure ulcer often exceeds$200,000 in costs. These financial considerationsfail to take into account the additional pain andsuffering experienced by the patients.
The Advisory Board Company estimated that60,000 deathseach year are associated with complications from
pressureulcers (Hiser, 2006; Brem & L der, 2004).

Risk factors for pressure ulcer development and theirprofile differ significantly across different healthcare scenarios with an underlying commondenominator underscoring the necessity tounderstand the pathophysiology of their
development. In acute care settings the incidence is highly variable-
5% to 15% (some reporting even higher values)
In long term settings the incidence varies between20% to 33%
In home care settings incidence varies between 0% to17%
Some wards have reported 0% pressure ulcer ratesfor long periods of time!!!!
Some obstetric wards have reported pressure ulcerrates in excess of 0.2% with a bias towards under
reporting!!!!! What is gong on?? Why is the risk so variable????
Pressure sores are they similar acrossdifferent settings.the clinical

Patients at risk of pressure ulcer development PROBLEM AREA 1 Traditionally certain patient subgroups have beenconsidered to be high risk for pressure ulcer
development -Elderly-Those with physical impairments due to amultitude of causes (neurological deficits, polytrauma, malignancies, thermal burns etc.)
Traditionally physicians and nurses undertook amore specific assessment of pressure ulcerdevelopment in only these specific settings oftenidentifying points for intervention too late whenmanifest pressure ulcers emerged.

Any patient who is bed fast and or chair fastshould be considered at risk for pressureulcer development.*
So dont harp on the illness in the scenario-offer screening assessment to all patientswith above risk characteristics points ofintervention will obviously depend on the
illness in scenario.

CAUTION -1
Pressure ulcers take hours to develop butmay take >7 days to manifest.
(what is seen today may be the result ofminor neglect in continuum of patient care
many days ago) CAUTION -2

THANK YOU 1962 THANK YOU 1987 There have been a multitude of scales available for
researchers which are still being validated acrossdifferent clinical scenarios.
But EPUAP and NPUAP have suggested following scalesto be used across different clinical profiles
GENERAL SURGICAL PATIENT - BRADEN SCALE* INDIVIDUAL RECEIVING PALLIATIVE CARE - Marie Curie
Centre Hunters Hill Risk Assessment Tool ORBraden Scale OR Norton Scale.
PEDIATRIC PATIENTS BRADEN Q SCALE. ICU PATIENTS Cubbin Jackson Scale**
**this scale and clinical scenario is not mentioned in the EPUAP and NPUAP clinicalguidelines.
*this scale has also been validated in an ongoing study in similar subset of Indianpatients (163) in Safdarjung Hospital Assessment of risk factors inpressure sores-A Tertiary Care Centre Experience, Chintamani,

PROBLEM AREA 2 - Strangely, this will NEVER HAPPEN with this
measure alone There is no decrease in pressure ulcer incidence
was found which might be attributed to use ofan assessment scale.
However, the use of scales increases theintensity and effectiveness of prevention
interventions *
Why ??? Further answers in anatomical andpathophysiological and psychosocial profiles ofpressure sores and the derived prevention andtreatment philosophy.

Actually the average number of bed sores noted over a periodof time in persons susceptible to bed sores is >1 (1.7 inmany studies)
Can you see how effects of nearby areas can alter themicrobiological profile of bacteria found in pressure sores ( Ecoli in wounds near the anus) (beta hemolytic streptococciand coagulase negative staph in wounds over occiput andother areas). Surprisingly pseudomonas aeruginosa isinfrequently found in pressure ulcers found in Indian studies(unless cocomitantly diabetes was present) *. Many bacteriamay be present in chronic wounds which may be mere
contaminants and colonisers but not critical colonisers orinfective (how about acinetobacter isolated in nonprogressive and slowly healing wounds)

It became clearly apparent to policy makersupon closer inspection that expensivemattresses and elaborate scoring systemsalone would give unsatisfactory results ifcontinuing care philosophy at all points ofhealth care including home did not includethe comprehensive elements of patienteducation and training, health provider
awareness, structured risk assessment,skin care and appropriately goal directedinterventions including nutritionalinterventions.

Annual incidence rates in developed world 20% to 30%and prevalence rates 10% to 30% with most commonsites being ischium, sacrum and trochanter.
25% of pressure ulcers in the community were classified assevere (Grade 3 or 4).
Other epidemiological studies indicate that 36% to 50% ofpersons with SCI who develop pressure ulcers willsubsequently develop another ulcer within 1 yearfollowing initial healing.
Individuals with paraplegia have the highest rate of recurrence, estimated at 80% (Wilhelmi &Neumeister,2002).
Our experience at Safdarjung Hospital (83 patients)
Patients with polytraumaand spinal cord injury as a groupdeveloped pressure ulcers more commonly than othergroup of patients.
Hemiplegics were least prone to develop pressure ulcersover the duration of hospital stay.
Paraplegic patients constituted the maximum number of
patients in the cohort but were found to develop pressureulcers at a rate similar to quadriplegics over the duration

Interesting insight into the behavioral patterns and risk of developingpressure ulcers once patients with SCI are discharged home
Patients who remain ulcer free perform on an
average 7.8 transfers from the wheelchair ascompared to 4.2 transfers for the patients whofrequently develop ulcers.
Patients who remained ulcer free were morelikely to be found with a positive employment
status. Finally, each group was asked what self-practices
they believed to be the most important inpreventing serious pressure ulcers. Statisticallysignificant differences betweengroups,ps < .05, were noted for three success factors:Participants in the ulcer-free group were morelikely to identify general activity level orsquirming (shifting in their chair) andsensation in the buttocks as important successfactors; those in the pressure ulcer group weremore likely to identify frequent skin checks and

In addition to the usual risk factors, certain additional risk factors havebeen identified
history of vascular disease
treatment with Dopamine or Dobutamine, intermittent haemodialysis(IHD) or continuous veno-venous haemofiltration (CVVH)
mechanical ventilation.
Also preventive measures were statistically positively associated withpressure ulcers grade 2-4: turning, floating heels, alternatingmattresses, adequate prevention.*
But some recent studies have concluded that There is no relationshipbetween pressure ulcer development and APACHE II score, or anymedication that affects skin integrity. The frequency of turning andrepositioning and patients with an emergency admission to the
ICU/HCU can be the prognostic indicators for developing scoringsystem in critical care settings. Relevance to clinical practice**
