Medical Education and Training

Dr. Kamau earned her Doctor of Medicine degree from the University of Nairobi, where she developed a strong foundation in internal medicine, complex disease management, and patient-centered clinical care.

She later completed her Internal Medicine residency training at the University of Oklahoma, where she further refined her expertise in diagnosing and managing complex medical conditions affecting adult patients.

Internal Medicine training provides a comprehensive understanding of the interconnected systems that influence healing. Conditions such as:

• diabetes

• cardiovascular disease

• kidney dysfunction

• malnutrition

• vascular compromise

frequently contribute to delayed wound healing.

Dr. Kamau’s training enables her to evaluate wounds within the full medical context of the patient rather than focusing solely on the skin surface. This systemic perspective forms the foundation of her approach to chronic wound management.

---

Board-Certified Internal Medicine Expertise

As a Board-Certified Internal Medicine physician, Dr. Kamau approaches wound care through the lens of whole-patient medicine.

Chronic wounds rarely exist in isolation. They often develop because of underlying physiologic dysfunction that impairs tissue repair.

Common systemic contributors include:

• diabetes and poor glycemic control

• peripheral vascular disease

• venous insufficiency

• cardiac disease

• renal impairment

• malnutrition

• neuropathy

• immobility

• medication side effects

• chronic inflammation

By addressing these root contributors alongside local wound treatment, Dr. Kamau’s approach improves healing potential and reduces the risk of complications such as infection, hospitalization, or limb loss.

This integrated medical strategy is a key differentiator between physician-directed wound care and fragmented treatment models that rely solely on topical wound management.

Founder of Midwest Wellness & Wound Care

Dr. Kamau founded Midwest Wellness & Wound Care to address a critical gap in post-acute medicine.

Many patients with chronic wounds live in environments where transportation to specialty wound clinics is difficult or unsafe. Skilled nursing residents, assisted living residents, and homebound individuals often experience delays in wound evaluation simply because they cannot easily travel to outpatient facilities.

The mobile wound care model solves this problem by bringing advanced wound care directly to the patient.

Under Dr. Kamau’s leadership, Midwest Wellness & Wound Care provides physician-directed bedside wound care services that allow patients to receive specialized treatment in the environment where they live.

This model improves:

• access to care

• early wound detection

• treatment timeliness

• interdisciplinary communication

• patient comfort and safety

It also allows physicians to observe real-world factors affecting wound healing, including mobility limitations, pressure exposure, nutritional status, and environmental risks.

---

Dr. Kamau currently holds active medical licenses in numerous states across the United States, allowing her organization to expand access to physician-directed wound care services across diverse regions.

States where Dr. Kamau is licensed in over 40 states. 

Operating across multiple states requires a deep understanding of regulatory frameworks, payer policies, and state medical board requirements.

Dr. Kamau’s leadership includes oversight of:

• multi-state physician licensing

• Medicare credentialing

• payer enrollment

• corporate practice of medicine compliance

• telemedicine regulations

• Medicare Administrative Contractor policy alignment

This regulatory fluency allows Midwest Wellness & Wound Care to expand safely while maintaining strict compliance with healthcare laws and reimbursement guidelines.

Mobile Wound Care: Bringing Advanced Treatment to the Bedside

Mobile wound care represents a major advancement in how chronic wounds are treated.

Traditional wound care models rely heavily on outpatient clinics or hospital-based services, which can create barriers for medically fragile patients.

Dr. Kamau’s physician-directed mobile wound care model places advanced wound care directly at the bedside.

Patients may receive care in:

• skilled nursing facilities

• assisted living communities

• rehabilitation centers

• long-term care facilities

• private residences

By eliminating transportation barriers, patients receive faster evaluations and more consistent follow-up.

Early intervention is one of the most important factors influencing wound healing outcomes.

Chronic Wounds Treated

Dr. Kamau’s clinical program manages a wide range of wound conditions commonly seen in post-acute medicine.

These include:

Diabetic Foot Ulcers
Neuropathy, vascular compromise, and metabolic dysfunction contribute to tissue breakdown.

Pressure Injuries
Prolonged pressure restricts blood flow and damages tissue.

Venous Leg Ulcers
Venous insufficiency and edema lead to chronic lower extremity wounds.

Arterial Ulcers
Poor arterial circulation limits oxygen delivery to tissues.

Post-Surgical Wounds
Incisions may fail to heal due to infection or systemic illness.

Traumatic Wounds
Skin tears and injuries are common in elderly populations.

Chronic Non-Healing Wounds
Persistent wounds require a comprehensive medical approach.

---

Structured Wound Evaluation

Every wound evaluation follows a standardized clinical protocol that includes:

• precise wound location documentation

• wound length, width, and depth measurement

• tissue type identification

• exudate evaluation

• periwound assessment

• infection surveillance

• perfusion evaluation

• pressure offloading strategies

This structured methodology supports accurate monitoring of wound progression and Medicare-compliant documentation.

---

Advanced Wound Treatment Modalities

Treatment plans are tailored to each patient and may include:

• conservative sharp debridement

• antimicrobial dressings

• moisture-balance therapy

• collagen-based wound matrices

• compression therapy

• edema management

• negative pressure wound therapy

• cellular and tissue-based products when appropriate

---

Medicare-Aligned Documentation

Providing wound care in long-term care environments requires careful adherence to Medicare documentation standards.

Dr. Kamau’s program emphasizes:

• medical necessity documentation

• CPT coding accuracy

• ICD-10 diagnosis specificity

• Local Coverage Determination adherence

• wound progression documentation

• treatment response monitoring

---

Telemedicine Services

In addition to mobile wound care, Dr. Kamau oversees telemedicine services that expand access to medical care.

Services may include:

• primary care consultations

• chronic disease follow-up

• medication management

• behavioral health support

• preventive care evaluations

Telehealth allows patients to receive ongoing medical support between in-person visits while maintaining continuity of care.
