Background: Pressure Ulcers (PU) §Incidence and costs of PU in USA l 280,000 hospital in-patients in 1993 rose 63% to 455,000 in 2003 1 l 257,412 Stage III / IV PU Medicare patients cost >$11 B in 2007 2 §Heavy clinical and caregiver burdens, worse in elderly l 72.3% of hospital in-patients with a PU were > 65 years of age 1 §PU reduce quality of life, increase costs of care l $37,800 mean charge/hospital stay principally for PU 1 §Evidence-based care heals most Stage II PU in < 12 weeks 3,4 §Inconsistent protocols of care impair PU prevention and healing efforts 5 1 Healthcare Cost & Utilization Project, AHRQ, 2006 2 CMS, 2007 3 Kerstein M. et al.

Rationale: The brewing PU storm § Professionals and institutions are held accountable for PU development and management. § Consistent evidence-based management improves PU incidence and outcomes. §Differences among PU protocols and guidelines confuse caregivers reducing consistency and quality of care and outcomes.
Objectives of AAWC Pressure Ulcer Care Initiative (PUCI) 1 § Evaluate current PU guideline recommendations l to assess need for one comprehensive, content- validated PU guideline 1 §Compile content validated unified list of all current PU guideline recommendations §Provide best evidence for each recommendation l to empower PU professionals and caregivers 1 Bolton L., et al. Ostomy Wound Management 2008; 54(11):22-30.
AAWC Pressure Ulcer Care Initiative (PUCI): Methods §Timeline: January, 2008 - February, 2009 lGuideline and literature searches: Jan-Oct, 08 lCompile, simplify published PU guideline items: Feb-Nov 08 lContent validate PUCI recommendations: Nov 08-Feb 09 lAnnotate recommendations with best evidence: Feb 08-ongoing §Funding: No industry funding to date lAAWC provided meeting room at SAWC08 and lAAWC connections for 12 teleconferences §Personnel: Volunteer AAWC-Member Guideline Team: l4 CWOCNs l3 CWCNs l2 Physicians l2 Physical Therapists (1 with PhD) l2 PhDs
AAWC PUCI: Methods §AAWC PUCI Content Validation Survey l Each recommendation rated for clinical relevance 1 = Not relevant 2 = Unable to assess relevance without further information 3 = Relevant but needs minor attention 4 = Very relevant and succinct §Evidence from MEDLINE, EMBASE searches l AHRQ (former AHCPR) criteria for levels of evidence Level A: At least 2 human pressure ulcer RCTs Level B: > 2 human PU non-randomized CTs or one plus a RCT Level C: Less than 2 controlled trials; opinion or case series l Each PUCI recommendation annotated with best 3 studies
AAWC PUCI: Results to date §Compiled 380 recommendations from: l 10 National Guideline Clearinghouse PU guidelines l Wound Healing Society PU guideline l Draft NPUAP, EPUAP PU guidelines
DifferencesImplications for Practice Definitions Improper or inconsistent staging, documentation affects outcomes and related reimbursement Procedures Inconsistent measurement and monitoring of progress delays recognition of impaired healing Content Effective interventions: Support surfaces? Nutrition? Care may be inconsistent if content is not uniform. Focus Provider focused content: e.g. RN, PT. Patient focus improves PU prevention, diagnosis and care. Evidence Level A ranged from 2 human PU RCTs to animal studies. Inconsistent clinical relevance of evidence. Validation Content validation adds validity and clarity to recommendations, reducing legal liability. Example Guideline Differences
Example Differences In Pressure Ulcer Measurement Methods Geometric (longest length x longest perpendicular width) measurements validated as an effective measure of total wound area and as a strong predictor of wound healing (p<0.05; n =260 wound patients) 1 1 Kantor J, Margolis DJ. 1. Arch Dermatol 1998; 134: 1571-1574. Ulcer orientation may change over time increasing error of Body Axis measurements e.g. head-toe may not be longest length. Geometric method avoids this error improving ability to monitor pressure ulcer progress: Across care settings During each episode of care Geometric Method of Measuring PU Length and Width
AAWC PUCI Content Validity Survey Survey and Respondent Characteristics §Content validation survey to1700 AAWC members + 40,000 readers of O/WM, open to all. §Clinical relevance ratings of recommendations 1 = Not relevant 2 = Too confusing to decide 3 = Relevant, need to improve 4 = Relevant and succinct §Respondents: N= 31 (26 female, 5 male) l 20 Nurse professionals (10 WOCNs, 1 NP, 1 CWCN) l 6 Physical Therapists l 2 Physicians (Physiatrist, Plastic Surgeon) l 2 Ph. D. l 1 Podiatric specialist §Most time spent in acute inpatient (61%) or outpatient (33%) care, home care (55%), office practice (50%), or group practice (33%)

Conclusions §Diverse guideline recommendations reduce consistency of PU care, confuse professionals and diminish outcomes. §To improve PU care consistency and outcomes AAWC GD tested content validity of published PU recommendations §Most recommendations had strong content validity (> 0.90) §Areas of confusion included some aspects of: l Psycho-social/quality of life l Skin and pressure ulcer evaluation l Skin and pressure care modalities for: Cleansing Debridement Advanced adjunctive therapies § Next steps: l AAWC GD compile evidence supporting all recommendations l Retain recommendations with A-level evidence and/or CVI > 0.75
