How should I write orders for an elderly immobile diabetic patient with peripheral vascular disease who has a stage III infected sacral pressure ulcer?

Orders for Stage III Infected Sacral Pressure Ulcer in Elderly Immobile Diabetic Patient with Peripheral Vascular Disease

This patient requires emergency multidisciplinary intervention within 24 hours due to the combination of infection and peripheral vascular disease, which creates exceptionally high amputation and mortality risk. 1

Immediate Emergency Orders (Within 24 Hours)

Vascular Assessment - STAT

• Measure ankle-brachial index (ABI), toe pressures, and transcutaneous oxygen pressure (TcPO2) immediately to quantify ischemia severity 2, 1
• Order urgent vascular imaging (color Doppler ultrasound, CT angiography, or MR angiography) to define arterial anatomy 2, 1
• STAT vascular surgery consultation if toe pressure <30 mmHg or TcPO2 <25 mmHg 2, 1
• Note: Do not rely on ABI alone in diabetic patients due to arterial calcification causing falsely elevated readings 1

Infection Management - STAT

• Obtain deep tissue cultures via surgical debridement or wound base scraping before initiating antibiotics (if patient clinically stable enough for brief delay) 3
• Blood cultures x2 sets 3
• Initiate broad-spectrum IV antibiotics empirically covering gram-positive (including MRSA if local prevalence >20%), gram-negative, and anaerobic organisms 2, 1, 3
  • Suggested regimen: Vancomycin PLUS piperacillin-tazobactam OR imipenem-cilastatin 3
  • Adjust based on culture results and local antibiograms 2

Surgical Intervention - STAT

• STAT surgical consultation for sharp debridement of all necrotic tissue, eschar, and surrounding callus 1, 3
• Imaging (X-ray and/or MRI of sacrum) to evaluate for osteomyelitis 3
• Consider deep abscess drainage if present 3

Wound Care Orders

Pressure Redistribution

• Place patient on alternating pressure mattress or air suspension bed immediately (69-76% relative risk reduction in pressure ulcer progression) 4
• Reposition every 2-4 hours (4-hourly schedule acceptable with specialized mattress) 4
• Avoid placing patient supine on sacrum; maintain 30-degree lateral positioning 4
• Australian medical-grade sheepskin under patient if alternating pressure unavailable (58% risk reduction), though less preferred 4

Wound Management Protocol

• Sharp surgical debridement of necrotic tissue and callus at bedside every 2-3 days until clean granulation tissue visible 1, 5
• Cleanse wound with pH-balanced cleanser (not soap and water) 4
• Apply moisture-retentive dressing appropriate for exudate level 5
• Photograph wound and measure length × width × depth in centimeters every 3 days 5
• Document percentage of granulation tissue, slough, eschar, and necrotic tissue 5

Metabolic Optimization Orders

Glycemic Control

• Target blood glucose <140 mg/dL 1, 5
• Insulin sliding scale with correction factor; administer prandial insulin immediately after meals 5
• Check fingerstick glucose before meals and at bedtime 5

Nutrition

• Consult dietitian for high-protein diet (1.25-1.5 g/kg/day) 5
• High-protein oral nutritional supplements TID if intake <75% of meals 5
• Monitor daily calorie counts 5

Incontinence Management (if applicable)

• Structured skin care protocol with pH-balanced cleanser for each incontinence episode 4
• Moisture barrier cream to periwound skin 4
• Consider rectal tube or fecal management system if severe diarrhea 4

Cardiovascular Risk Management

• Statin therapy (high-intensity) 2, 1
• Antiplatelet agent (aspirin 81 mg daily OR clopidogrel 75 mg daily) 2, 1
• Blood pressure control targeting <140/90 mmHg 1
• Smoking cessation counseling and pharmacotherapy if applicable 2, 1

Monitoring Orders

• Daily wound assessment documenting size, drainage character/amount, periwound erythema, warmth, induration 5
• Daily inflammatory markers (ESR, CRP) to evaluate treatment response 3
• Monitor for fever, increased confusion, worsening pain, or increased drainage 5
• Reassess for revascularization if ulcer does not improve within 6 weeks despite optimal management 2

Antibiotic Duration

• Minimum 2-4 weeks for severe soft tissue infection depending on clinical response 3
• Minimum 4-6 weeks if osteomyelitis confirmed 3

Critical Pitfalls to Avoid

• Never delay revascularization consultation while attempting medical management alone—infected ischemic ulcers are surgical emergencies 1
• Do not use antiseptic-only treatments; proper wound care with appropriate dressings is essential 1
• Failure to identify osteomyelitis and inadequate surgical debridement are the most common causes of treatment failure 3
• Infection increases metabolic demand while ischemia prevents adequate perfusion—this vicious cycle requires breaking both components simultaneously 1

Multidisciplinary Team Coordination

• Daily rounds with wound care nurse, vascular surgery, infectious disease, endocrinology (if available), and primary team 2, 1
• Weekly reassessment by full team if healing progresses; more frequent if deteriorating 5
