Part 1: An Introduction to TIME
|
Patients referred to a wound care clinic must be prepared to heal. Despite innovative, new technologies such as growth factors, bio-engineered skin products, and vacuum-assisted closure, chronic wounds will not progress to healthy closure without consideration of a number of patient and wound factors. Clinicians must address key initial components of wound management treat the cause of the chronic wound, appraise patient-centered concerns, determine wound chronicity/location/dimensions/condition, and assess pain and ensure the wound bed is appropriately prepared. Only then can the maximum benefits from advanced wound care products be derived and wound healing achieved.

Part 2: TIME for Venous Ulcer Management
|
Chronic wounds present a unique set of challenges for wound care clinicians. Unlike acute wounds that progress through four phases to closure, chronic wounds become stuck in the intermediate phases and require intervention to remove the barriers to healing and to restart the healing process. Specific wound types, such as venous ulcers, require particular approaches within the realm of wound bed preparation to remove major obstacles to optimal closure of the chronic wound.

Part 3: The Role of Silver in Infection Control
|
Wound bed preparation is a new approach that integrates proven concepts to build a platform for the treatment of chronic wounds. It organizes currently approved medical procedures and products into a holistic approach that can be used to evaluate and remove barriers to the wound-healing process. Removal of such barriers allows for optimal wound repair and healing. To address these barriers, a systematic approach to the management of chronic wounds has been developed. The approach goes by the acronym TIME (tissue: non-viable or deficient; infection or inflammation; moisture imbalance; and edge of wound: non-advancing or undermined) the goal is to establish a well-vascularized wound bed that facilitates the effectiveness of other therapeutic measures.

Part 4: Debridement and the Role of Enzymes
|
An important aspect of the TIME principle is the need to address nonviable or deficient tissue and restore the wound base and extracellular matrix proteins. In acute wounds, wound debridement is an effective way to remove necrotic tissues and bacteria so the wound can heal with relative ease. This is not the case for chronic wounds, where much more than debridement needs to be addressed for optimal results. Chronic wounds, such as venous ulcers, have a necrotic burden consisting of both necrotic tissue and exudate as such, these wounds can be intensely inflammatory. They produce substantial amounts of exudate that interfere with healing and the effectiveness of therapeutic products such as growth factors and bioengineered skin. Therefore, in the context of wound bed preparation, clinicians need to remove not only eschar and frankly nonviable tissue, but also wound exudate.

Part 5: Moisture Imbalance and the Chronic Wound
|
Wound care has progressed rap idly during the last 20 years. If clinicians and their patients are to fully benefit from the sophisticated therapies currently available, as well as those currently under development, a greater understanding of the basis of proper wound care is essential. Unless the wound is properly prepared, neither conventional nor advanced therapies (eg, gene therapy, recombinant growth factors, or bioengineered skin grafts) will prove as effective as they can be.
|
Part 6: Infection and Inflammation
|
Wound infection delays wound closure. It prolongs the inflammatory phase of healing and often causes distress and discomfort for patients. Wound infections also have considerable financial implications due to increased length of hospital stay, the additional cost of antimicrobial therapy, and a higher incidence of related wound management complications.
|
Part 7: Protecting Skin from Breakdown
|
The prevalence of incontinence in the elderly increases this population’s risk for skin breakdown, particularly pressure ulcers. Moisture increases shear and friction on the skin, which affects skin permeability and barrier function. Enzymes present in urine and fecal matter exacerbate these negative effects; cleansing can be abrasive and further disrupt the skin’s natural chemical environment. Skin breakdown is costly. Treatment expensive and quality-of-life issues are challenging. Plus, because pressure ulcers awareness in both the public and judicial sectors has increased, the potential monetary and emotional expense of litigation must be considered.
|
Part 8: Burn Wound Care
|
Burn care is complex. It involves multisystem assessment, multidisciplinary care, and appropriate interventions. Only after the burn care professional is fairly certain the patient will survive the burn injury can treatment goals focus on burn wound closure. Inpatient hospital stays for burn patients range from a few days for small partial-thickness burns that heal on their own to several months for patients with large total body surface area burns and deep burns that often are exacerbated by other medical complications and require multiple surgeries to achieve wound closure.
|
Part 9: Incorporating a Dermal Substitute
|
During the normal process of wound healing, a series of molecular events prepare the wound for repair, deposition of new extracellular matrix, and eventually complete wound closure. This orderly process of cellular control is impaired in chronic wounds, delaying or interrupting the repair process.
|
Part 10: The Wound Bed Preparation Care Cycle
|
Wound bed preparation and the TIME principle facilitate evaluation and treatment of chronic wounds. Earlier articles in this series discussed the components of TIME and how this approach can be used to treat specific wound types such as venous ulcers and diabetic foot ulcers.
|
Part 11: A Concept for Pressure Ulcers
|
Pressure ulcers are a costly, often unpredictable challenge for clinicians. Although these wounds have been managed successfully for years, increased awareness among governing bodies and healthcare providers regarding the need for prompt, appropriate pressure ulcer management has sparked a renewed interest in improving care. The National Pressure Ulcer Advisory Panel (NPUAP) is currently revisiting its understanding of pressure ulcer physiology the results of its considerations potentially will affect the way pressure ulcers are staged and treated. Meanwhile, the Centers for Medicare and Medicaid Services (CMS) has increased scrutiny of pressure ulcer management in long-term care, introducing revisions to its pressure ulcer management guidelines; similar guideline implementation is anticipated for acute care. Pressure ulcers and their possible implication in substandard care litigation are fueling public awareness of the pressure ulcer conundrum. Obviously, diligent healthcare providers need to find the optimal balance between providing quality care and managing expenses.
|
Part 12: Benchmarking Outcomes
|
Attention to underlying wound etiology and factors that affect healing, combined with the TIME Principle for Wound Bed Preparation, can be a powerful model for healthcare providers who manage patients with chronic wounds. Wound bed preparation is an important part of the care process, as is the ability to evaluate and benchmark the effectiveness of individual treatment modalities and the overall quality of care provided within a facility. In addition, assessing performance can fuel a facility's outcomes-based quality improvement (OBQI) program and the ability to benchmark with others can help a facility achieve "best practice" status.
