Abstract

Keywords: Role of nurses; holistic approach; evidence based medicine; critical pathways

Optimal care of the burn patient requires a distinctive multidisciplinary approach. Positive patient outcomes are dependent on the composition of the burn care team and close collaboration among its members. At the centre of this team is the burn nurse, the coordinator of all patient care activities. The complexity and multisystem involvement of the burn patient demand that the burn nurse possess a broad-based knowledge of multisystem organ failure, critical care techniques, diagnostic studies and rehabilitative and psychosocial skills. The nurse oversees the total care of the patient, coordinating activities with other disciplines such as occupational and physical therapy, social services, nutritional services and pharmacy. At the same time, the burn nurse is also a specialist in wound care. As a burn wound heals, either spontaneously or through excision and grafting, the nurse is responsible for wound care and for noting subtle changes that require immediate attention, prevention of infection and pain management. The nurse's role is continuously expanding. Nurses are conducting nursing research and contributing to evidence-based practice of burn care. Practice guidelines, critical pathways and nursing care plans are all tools that help define and refine the nurse's role in burn care.

Evidence-Based Practice

Recent advances in health care technology, public disclosure and published information as well as a realization that we are obligated to reduce prohibitive health care costs are some of the several factors that have promoted the interest in and development of evidence-based practice or a more objective, scientific approach to health care. Previous standards of care, based largely on experience, are now being used as a control in randomized clinical trials. Both are evaluated using specific endpoints such as cost, benefit and risk. ^[1] Barnsteiner and Provost ^[2] suggest that there are both research and nonresearch elements in evidence-based practice. Clinical judgment and critical thinking are equally vital to the process.

Practice Guidelines

Practice guidelines have evolved from the evidence-based practice revolution. They are intended to provide recommendations based on critical reading and interpretation of the current literature for managing specific problems. They attempt to define not only the best but also the most cost-effective treatment. When correctly written, practice guidelines can help minimize practice variances that lead to poor patient outcomes and high health care costs. Because burn centres are few in number and are geographically scattered, there are few burn-focused multicentre trials. Many burn research studies involve only one centre, animal models and small sample sizes. Their limited strength of any demonstrated findings and study conclusions is obvious. There are currently a minimal number of randomized controlled clinical trials that have validated burn clinical care practices. Of the few that do exist, many have been extrapolated from research performed in other critical care patient populations. Recent efforts by the American Burn Association to initiate and support collaboration between burn centres to conduct multicentre trials are on-going. The resulting research studies should generate evidence-based practice and greatly impact future burn care. Additionally, the American Burn Association Committee on Organization and Delivery of Burn Care has published updated Practice Guidelines that were originally published in 2000 as a supplement to the Journal of Burn Care and Rehabilitation. The revised and updated recommendations represent the work of the 2004 to 2006 Committee on the Organization and Delivery of Burn Care. ^[3]

Critical Pathways

Critical pathways that were developed in the late 1990s as another measure to guide medical and nursing practice are more detailed disease and institution-specific protocols that are usually based on practice guidelines. They define the sequence of standardized, multidisciplinary processes or critical events that must occur in order for a particular patient to move toward desired outcomes within a defined period of time. The goal is to use an interdisciplinary perspective to identify expectations of patient care, improve quality care as demonstrated by improving patient outcomes, decreasing length of stay, decreasing readmissions, decreasing costs and increasing patient satisfaction. ^[4] They define anticipated length of stay, delineate desired outcomes and goals, provide directions for care, identify the best practice model for a specific group of patients, promote collaboration between disciplines and provide an opportunity for continuous improvement in care delivery.

Critical pathways represent the standard of care in average cases and were developed in response to economic incentives and pressures as they encourage the proper use of resources, which in turn reduces waste of time, energy and material. They promote well-coordinated, well-communicated continuity of care through collaborative practice and facilitate adherence to regulations imposed by regulatory bodies, reduce length of stay and resource utilization and reduce practice variances and adverse outcomes. [Table - 1] summarizes some of the various purposes that are served by critical pathways.

Implementation of critical pathways is challenged by many pros and cons. While they provide a useful guideline in assessment, intervention and evaluation, they must be constantly monitored and updated based on the patient's response to therapy. Further, they must be individualized for each patient's needs. ^[5] They should not to be construed as a cookbook mentality. They are not laws that must be rigidly followed. Contrary to popular belief, they do not annihilate individuality. It is important to remember that they are guidelines that outline the current standards of care. They also provide a useful educational tool for all members of the burn care team as they reflect each team member's responsibilities. The nurse spends the most time with a patient and is in the best position to monitor progress, report changes and coordinate activities of other team members. Critical pathways are most commonly depicted along two axes, one representing time and one representing aspects of care, including laboratory studies, consult services, nutrition, pharmaceutical support, patient education, etc.

Another useful element of critical pathways is their ability to identify variances, or unexpected events, both positive and negative. The analysis of these variances provides an excellent framework for a quality improvement program and can help focus improvement efforts in any of the four major areas: caregiver or provider, hospital or system, patient or family and/or community variance.

Nursing Diagnoses and Care Plans

During all phases of injury, assessment by the nurse must focus on early detection or prevention of complications associated with moderate to severe burn injury. Frequent monitoring is required to assess indices of essential organ function. A list of the more common actual or potential nursing diagnoses for patients with thermal injuries in the resuscitative, acute and rehabilitative phases of care is presented in [Table - 2]. ^[6]

The nurse's goal is to deliver patient-focused care using a holistic approach. In order to accomplish this, the nursing process was introduced in the 1950s and has served as the framework for nursing care delivery ever since. The process uses a scientific method to combine systems theory with the art of nursing. It entails both problem-solving techniques and a decision-making process. ^[7] The nursing process consists of five steps, which together facilitate the delivery of high-quality, individualized patient care. The five steps are as follows:

Assessment is the first step of the process and is a systemic approach to collecting information about the patient. It includes not only symptoms and physiologic factors but also social, cultural, psychological and spiritual aspects of the patient's life.

Diagnosis, the second step, is the nurse's analysis of the assessment. It is sometimes also referred to as needs identification.

Outcomes/planning uses the two previous steps to determine patient goals, both long- and short term, desired outcomes and appropriate nursing interventions. These outcomes and interventions are written as the nursing care plan and serve as a written guide for all health care professionals. An example of a written nursing care plan for the patient in the resuscitative and acute care phases of a major burn injury is provided in by Molter et.al and Ahrns-Klas. ^[8],[9]

Implementation is the action portion of the nursing process and care plan.

Evaluation of both the patient's response to interventions and progress toward achieving outcome goals is critical. Both need to be documented and the plan of care modified accordingly.

The nursing process is both dynamic and interactive. It is a continuous cycle of logical progression from one step to the next. Because each step relies of the accuracy of the previous step, data must be validated. Clearly, the plan that is developed from the nursing process must be adjusted based on the interactions with other disciplines in order to meet the continuously changing needs of the patient. In creating the care plan, the nurse uses theory, nursing judgment and clinical expertise. In many ways, the nursing process and written plan of care help define the nurse's role. By using the nursing process, the nurse is able to establish autonomy and a common ground within the practice of nursing through nursing diagnoses. The continuous review of the care plan facilitates evaluation and documentation of outcomes and helps provide the basis for establishing standards of care.
