BARIATRIC NURSING AND SURGICAL PATIENT CARE Volume 5, Number 1, 2010 ª Mary Ann Liebert, Inc. DOI: 10.1089=bar.2009.9940 Original Articles Applying Middle-Range Nursing Theory to Bariatric Surgery Patients: Experiencing Transitions Shannon Reedy, MS, CRNP,1 and Kay Blum, PhD, CRNP 2 Abstract Obesity has reached epidemic levels in the United States, and bariatric surgery is becoming an increasingly prevalent intervention. Nurses play an integral role in the care of these patients before, during, and after surgery. Using theory in practice provides a systematic, organized space that promotes a comprehensive yet individualized approach to patient problems. Middle-range theories, such as the theory of experiencing transitions, can easily be used for research and practice development. The theory was described and evaluated for substantive foundations, structural integrity, and functional adequacy. The evaluation demonstrates the use of the theory in nursing practice and research with patients experiencing the transitions associated with bariatric surgery. aspects affected by obesity such as well-being, quality of life, and social stigmatization.7–9 Multiple studies, as demonstrated in a 2005 meta-analysis, have shown the safety and efficacy of bariatric surgery as a treatment for morbid obesity.10 The rate of bariatric surgery increased from 26.8 to 43.7 per 100,000 covered lives between 2001 and 2006.11 In 2006, estimated rates of bariatric surgery were around 180,000 and are expected to steadily rise.3 Introduction Significance of the problem O besity has reached epidemic levels in the United States. According to the Center for Disease Control’s 2007 statistics, Colorado was the only state with obesity prevalence rates less than 20% and three states had obesity rates at 30% or higher.1 From 2005 to 2006, 34.3% of adult Americans were obese.2 From 2003 to 2004 the prevalence of extreme obesity (defined as a body mass index higher than or equal to 40 kg=m2) was 4.8%, approximately 15 million Americans.3 Projections are that 51.5% of adults will be obese by 2030 and that 100% of adults will be obese by 2102.4 Obesity has been linked to numerous chronic health conditions including hypertension, hyperlipidemia, sleep apnea, type 2 diabetes, and heart disease.5 Obesity-associated conditions significantly increase hospital length of stay, mortality, and overall healthcare costs.6 In addition, there are a multitude of psychosocial Physical outcomes of surgery Studies have shown that bariatric surgery is more effective than nonsurgical weight-loss treatments for patients with a body mass index (BMI) of 40 kg=m2.10,12 Bariatric surgery results in dramatic weight loss over a very short time. A 2004 meta-analysis examined 136 studies with a total of 22,094 patients found that the overall percentage of excess weight loss for bariatric procedures was 62.1%.13 Patients commonly experience weight loss of 100 pounds or more 1University of Maryland Medical System, Adult and Gerontological Nurse Practitioner Program, University of Maryland School of Nursing, Baltimore, Maryland. 2University of Maryland Medical System, University of Maryland School of Nursing, Baltimore, Maryland. 35 36 during the first year. The physical changes are intricately interwoven with the psychological changes. Much like a small tap will shatter a glass that is already cracked, the dramatic weight loss may shatter one or more relationships that were already strained. Psychosocial outcomes of surgery Well-designed bariatric surgery programs include psychological evaluation and counseling designed to help potential surgical candidates develop realistic expectations about the effects of weight loss on their happiness and their relationships. While bariatric surgery patients typically report increased quality of life, improved relationship satisfaction, and improved sexual satisfaction, untoward consequences may result.14 For example, disease-related deaths are reduced after bariatric surgery, yet deaths from accidents and suicide increase by a factor of 1.58.15 A preoperatively dysfunctional marriage will likely still be dysfunctional postoperatively and after weight loss. Well-meaning friends and family members may sabotage the change in eating patterns out of habit, out of the need to control, or as a deliberate attempt due to personal gain in maintaining the patient’s obesity. The loss of friends, loss of family support, or divorce may result. These losses may also sabotage the weight loss. Theory-Guided Nursing Care A nurse’s role in helping patients with the positive outcomes and potential negative outcomes of bariatric surgery is significant. Incorporating theory into practice is vital for the future of bariatric nursing, but selecting a theory that is fitting to the practice problem is essential. Using theory in practice provides a systematic, organized space that promotes a comprehensive yet individualized approach to patient problems. Middle-range theories can easily be used for research and practice development. This article looks at the use of one middle-range theory, the theory of experiencing transitions (ET), and its applicability to bariatric nursing practice and research. As leaders in patient care, nurses need to continue to develop guidelines for the care of this vulnerable population. Incorporating nursing Bariatric Nursing, vol. 5, no. 1, 2010 REEDY AND BLUM theory into this process involves investigating themes. Change is a recurrent theme in bariatric nursing care. Change is endless in healthcare, and change, regardless of the type, has an impact on the patient. Subsequently, change is often associated with transition; therefore, transition may be viewed as a central concept in nursing of bariatric patients. Meleis and colleagues16 developed ET to help describe how individuals experience the multiple transitions each person goes through during a lifetime. The theory of ET proposes that a key role of nurses is to assist patients in managing life transitions. With every surgical intervention, every birth and every death, there are a multitude of transitions. Bariatric surgery, with the dramatic weight loss, the profound changes in eating and approach to food, as well as the resulting changes in body image—all of which affect relationships—must be considered a transition and not merely a change. The person who undergoes this dramatic transformation experiences multiple transitions. The role of the bariatric nurse is to help that person draw on personal and professional resources that assist in a positive and satisfying transition. Theory of Experiencing Transitions Transitional theory has its origin in sociology and anthropology. Van Gennep discussed transitions in his book The Rites of Passage long before the middle-range nursing theory ET emerged.17 The theoretical framework for ET (Figure 1) can be divided into three areas: nature of transitions, transitional conditions, and patterns of response.16 Types, patterns, and properties are considered the nature of transitions. Transition conditions can be either facilitating or inhibiting. Process indicators and outcome indicators are considered patterns of response.16 Nature of transitions Types of transitions include developmental, health=illness, situational, and organizational. Developmental transitions include life span transitions such as adolescence, aging, pregnancy, childbirth, and death. Diagnosis of disease, surgical procedures, and rehabilitation are health=illness transitions. Persons undergoing bariatric surgery often have one or more MIDDLE-RANGE THEORY AND BARIATRIC SURGERY PATIENTS Nature of Transitions Types Transition Conditions Patterns of Response Personal Patterns Properties 37 Process Indicators Society Outcome Indicators Community NURSING THERAPEUTICS FIG. 1. Experiencing transitions. comorbidities that, over time, have led them to identify with that chronic disease process or to identify themselves by their obesity. These changes in identify are the product of previous transitions but are amenable to change with the right help. Situational transitions are transitions such as divorce resulting from the changes in interpersonal dynamics in the family now that the formerly obese individual has changed the way they see the world and their role in it. Organizational transitions could be those associated with change in leadership within the family or other social or professional groups.16 A once passive, obese wife may now find her voice after her weight loss and disrupt the family’s status quo. Patterns of transitions are many. They can be single, multiple, sequential, simultaneous, related, or unrelated.16 When the transition occurs singly, it occurs in absence of any other transition. Multiple transitions are likely more common. This means that at least two transitions are occurring at once. An example of multiple transitions is transitioning from morbid obesity to normal weight, a new body image as well as a new interpersonal dynamic. The transitions can occur sequentially, one after the other or they can occur simultaneously. The transitions can be related to each other, such as the transition from obesity to normal weight. The transitions could be unrelated, such as losing weight and completing a college degree. In addition to varying types and patterns, the experience of a transition also has many properties. Awareness, engagement, change and difference, transition time span, and critical points and events are all properties of a transition. Awareness refers to a person’s recogni- tion of the transition. Awareness is considered an important property of a transition.16 Chick and Meleis purported that if a person was not aware of the transition that they may not actually be going through a transition.18 There is some discourse over the idea. In 2000, Meleis et al. posed that awareness by the person is not a necessity for a transition to begin.16 They suggested that someone else, such as a nurse, could be aware of the transition, which could then serve as the starting point of the transition. Engagement is another property of a transition and refers to active, deliberate involvement in the transition. Engagement relies very heavily on awareness. A person is unable to become engaged in their transition if they are unaware of the transition. Engagement involves seeking out information and being active in the transition process. Someone who has decided to undergo bariatric surgery would be transitioning to a nonobese body image. Engagement for this person would be seeking professional help to deal with the change in interaction with others, to deal with people who would sabotage their weight loss, or just to discuss their own inner changes. These are deliberate activities that require awareness of both the transition and the day-to-day issues that determine the success of the transition. Engagement in the strategies improves the likelihood of that success. A third property of transitions is change and difference. Meleis and colleagues16 note the lack of reciprocity between change and transition. They state that change and difference cannot by thought of synonymously with transition. All transitions involve change, but not all change is related to transition. Transitions Bariatric Nursing, vol. 5, no. 1, 2010 38 are both the result of change and result in change.16 Change should be thought of as an occurrence that precipitates a transition or that occurs because of a transition. In contrast, difference refers more to perception than an occurrence. Feeling different or having a different expectation is not the same as a change. For instance, a 100-pound weight loss is a dramatic change, but some people look in the mirror and perceive no difference because they still see the obese person in the mirror. Time span as a property of transitions refers to the period from when the transition began until it ended. Placing a time span on a transition is difficult. It can be particularly difficult to determine the end of a transition in many cases. The end of a transition typically occurs when a new period of stability occurs.16 When a person loses all the weight they can after the procedure, the physical change is complete, but the transition continues until the weight change is incorporated into the self. For a period, they may have trouble dealing with the changes to their life, their body, and their health. Determining exactly when the transition ends may prove to be difficult. One could say when a person reaches a point where they have stabilized and have come to terms with the weight loss and the other associated changes is when the transition has ended. Meleis and colleagues also indicate that a transition may lie dormant and reemerge.16 Alternatively, patients may experience several transitions surrounding the same type of transition. If someone transitions from obese to normal weight, stabilizes, and then regains the expected 10% of body weight several months later, you could say that they had a reemergence of an old transition or have begun a new transition. Critical points and events are the final property of transitions and are not apparent in every transition. They are specific markers that identify a point in the transition. Often critical points are either the beginning or the end of the transition.16 The decision to undergo bariatric surgery is a critical point in embracing a permanent solution for obesity. Often this decision takes place in the presence of a history of unsuccessful attempts or very successful weight loss that could not be maintained. Knowledge of occurrences, feelings, symptoms, and changes that typically occur around critical points Bariatric Nursing, vol. 5, no. 1, 2010 REEDY AND BLUM in a transition allow a nurse to help patients through transitions. Transitional conditions Many conditions affect a transition. Personal, community, or society conditions can either facilitate or inhibit a transition. Personal conditions include meanings, cultural beliefs and attitudes, socioeconomic status, and preparation and knowledge. Meanings may have positive or negative influence over a transition. Meaning refers to the perception the person experiencing the transition has about the transition. The person undergoing bariatric surgery and the change in eating understands the difficulty of the choice and may be hurt when others dismiss the surgery as ‘‘the easy way out.’’ Cultural belief and attitudes play a large role in transitions. In a culture where women feel they are valued based on their weight and appearance, they may choose bariatric surgery to achieve the acceptance they desire only to experience marginalization for some other reason, thereby decreasing the perceived value of the sacrifice related to the demands of the surgery and eating changes that are required. Perhaps this explains why some persons regain all their weight.19,20 Socioeconomic status is an important condition in a transition because it may impact how people handle their transition. If a person does not have an automobile, they may not seek out support groups that could help them deal with unmet expectations. Preparation and knowledge regarding an impeding or current transition may be facilitative or inhibitory. In nursing we choose to believe that planning and preparation reduces or eliminates these unrealistic expectations, but the individual may or may not modify expectations based on the information they are given. An example might be acknowledgement of the information, but the refusal or inability to personalize the information. Lack of knowledge may inhibit transition.16 Community conditions can influence transitions as much as personal conditions. The community resources in some areas are much greater than in others.16 If a bariatric surgery patient lives near a hospital that has a postoperative support group, she may experience her transition very differently than a woman who does not have that available in her community. MIDDLE-RANGE THEORY AND BARIATRIC SURGERY PATIENTS Societal conditions can also facilitate or inhibit transitions. Meleis and colleagues use gender inequity as an example of how a transitional event can be affected by society.16 A woman may place her healthcare needs below those of her family in some societies. Women are more empowered, in some societies, to seek care for conditions such as obesity than in others. Patterns of response Process indicators and outcome indicators describe how a person moves through and arrives at the end of a transition. These indicators are often thought of as consequences of a transition, but they can occur at any time throughout the transition. An outcome need not happen at the end of the transition. Nursing assessment of these indicators should occur to determine whether a person is making a healthy or unhealthy transition. Nursing interventions and therapeutics can then take place to facilitate the transition.16 Process indicators include feeling connected, interacting, location and being situated, and developing confidence and coping. Feeling connected refers to personal contacts and connections to friends, family, and health professionals.16 Feeling connected to friends and family offers social support, where feeling connected to healthcare workers can provide a source of information. Interacting with others is important in the process of the transition. How people interact with each other differs greatly and can have an enormous impact on transitioning. There may also be groups or individuals who have a vested interest in the individual remaining obese, and they may actively or passively try to sabotage that person’s success with weight loss. There may be others who are simply afraid for the patient to have surgery. If it is a family member or close friend, the individual who has chosen bariatric surgery may have to choose between losing weight and harming the relationship with their family or friends. The nurse can help to increase awareness of the outcomes for the individual if they continue in the self-defeating patterns versus actively engaging in a new pattern of interaction. Location and being situated can be important when a patient experiences a transition. Hospitalization versus staying at home during an 39 illness has an affect on how someone transitions. This also refers to a person’s comfort with where they are in their transition. Confidence and coping show how a person has developed strategies for managing their condition. Meleis and colleagues describe it as the accumulation of experiences and thought transformation that results in wisdom.16 Outcome indicators include mastery and fluid integrative identities. The time at which the outcome indicators are assessed is important.16 Outcome indicators examined too early may not be complete, and those examined too late may be influenced by other transitions. Mastery indicates the skills that have developed to deal with the situations. Mastery of the transition in the self or body image might include knowledge of its effect on eating patterns, monitoring weights, taking vitamins properly, and making appropriate medical appointments. Fluid, integrative identity describes the restructuring of the person’s identity to include the transition. The person’s being actually changes as part of or because of the transition. This change is a dynamic process. Experiencing Transitions in Terms of Bariatric Surgery Transition is a concept that has broad nursing applications as well as specific application to bariatric surgery patients. The ET theory provides a framework to examine how bariatric surgery patients transition and how nursing interventions might affect them. Bariatric surgery patients experience a multitude of transitions. Bariatric surgery can be viewed as a health=illness type of transition but may also encompass situational and organizational transitions. Long before surgery, patients may begin to experience a transition as single, multiple, sequential, or simultaneous. At some point they surrender to the fact that they are not able to lose weight without surgical intervention. Personal, community, and societal conditions may have an impact on their decision to have surgery. The process of thinking about weight loss may be the beginning of their first transition. Awareness of the transition that they will go through is paramount. Successful weight loss and maintenance of that weight loss requires active engagement on the part of Bariatric Nursing, vol. 5, no. 1, 2010 40 the patient and cannot be achieved by a passive subject. A critical event, one of the properties of a transition, may be their first visit with the bariatric surgeon. Or, surgery may be seen as the critical event. Preparation and knowledge is instrumental in the success or failure of bariatric surgery. Massive weight loss causes changes that are incomprehensible to the patient and their family. Massive weight loss is not just a physical change; it is well documented that some patients suffer from family crises after weight-loss surgery. Occasionally a spouse becomes jealous and insecure about themselves when their spouse loses weight. Weight loss increases the self-esteem of the bariatric surgery patient, and they may be unwilling to put up with belittling behavior that they previously felt they deserved. These psychosocial issues may create other transitions for the patient to go through. Not only could ET theory be used to examine the transitions of patients, it could be used to examine the transitions of their family members and how nursing interventions could assist them as well. Evaluation of Experiencing Transitions Theory Theories are not inherently good or bad. Their value lies in the ability to help a researcher or provider apply a systematic framework to the evaluation and=or solution for a particular problem. By evaluating theories, we can determine the usefulness of a theory and determine areas where further work can be done to improve it. Using Smith’s framework, ET theory was evaluated for substantive foundations, structural integrity, and functional adequacy.21 Substantive foundations The assessment of substantive foundations is based on four criteria. The first criterion evaluates whether the theory is within the focus of the discipline of nursing. Although transition theories are rooted within the discipline of anthropology, ET theory is certainly within the discipline of nursing. If one defines nursing as caring for and about human beings throughout their life span as they experience health and illness, then exploring and assisting individuals Bariatric Nursing, vol. 5, no. 1, 2010 REEDY AND BLUM through transitions would seem to exemplify that definition. The ability of the theory framework to suggest interventions that help guide nurses working with bariatric surgery patients as they transition from obese to normal weight supports the focus of the discipline of nursing. The theory then meets this criterion. The second criterion requires that the assumptions are specified and are congruent with the focus. The assumptions of ET theory are not explicitly mentioned in the description of the model; however, they can be inferred from the discussion. They are: 1) transitions are complex and multidimensional, 2) awareness of the transition is a requirement for the process, and 3) each individual brings their own personal meanings and resources to common transitions making each transition process unique. These assumptions are consistent with the focus of nursing practice in bariatric surgery. The third criterion requires that the theory provide a substantive description, explanation, or interpretation of a named phenomenon at the middle-range level of discourse. The named phenomenon is transition. The theory of ET provides an excellent description, explanation, and interpretation of the transitional process. It clarifies concepts from previous works, distinguishes transition from change, guides practice, and poses questions for further research. Transition is at the middle-range level in that it is defined in a measurable way and can be operationalized in both research and practice settings. The fourth criterion requires that the origins are rooted in practice and research experience. Schumacher and Meleis performed an extensive review of the literature in their 1994 article on transitions.22 Meleis and colleagues again searched the literature for studies using nursing transition theory to develop and define concepts of ET.16 Kralik et al. identified a multitude of papers published on transitions between 1994 and 2004 by searching CINAHL, Medline, SocioFile, and Psychlit (www.lib.uidaho.edu= tutorial=psychlit_database.htm) databases.23 Many studies have used transition theory in their research and practice. Skärsäter and Willman used ET theory to gain a deeper understanding of the concept of transition in the recovery process associated with major depression and to suggest nursing MIDDLE-RANGE THEORY AND BARIATRIC SURGERY PATIENTS interventions to support the recovery process.24 Weiss and colleagues used Meleis’ theory to identify predictors and outcomes of adult medical-surgical patients.25 In practice, Wilkins and Woodgate used ET theory to provide a framework for how nurses could assist with transitions in siblings of children with cancer.26 Davies evaluated whether ET theory could be used to assist relatives of patients admitted to nursing home with their transition.27 Structural integrity The first criterion of structural integrity is that the concepts are clearly defined. The concepts in ET theory are very easy to understand. They are individually described and defined. In addition, they are used in examples so that they can be understood in context. The second criterion of structural integrity is that the concepts within the theory are at the middle-range level of abstraction. The main concepts of ET theory—transition, personal facilitators and inhibitors of transition, patterns of response, and nursing therapeutics—are middle-range concepts because they can be operationalized and measured.24 The third criterion of structural integrity is that there are no more concepts than needed to explain the phenomena. Overall, the concepts adequately explain the phenomena of transitions. In the concept of transition conditions, there is some interaction. The three main areas are personal, community, and society. Even though there are separate categories for community and society, personal conditions include cultural beliefs and attitudes and socioeconomic status. These three concepts could be delineated a bit further as could nursing therapeutics, which is not addressed in the discussion.16 The forth criterion of structural integrity is that the concepts and relationships among them are logically represented with a model. Experiencing transitions theory uses a logical flowchart-type model. Meleis and colleagues developed a concept map and included it with their 2000 publication ‘‘Experiencing Transitions: An Emerging Middle-Range Theory.’’16 The model is easily understood and outlines all of the key concepts of the theory. 41 Functional adequacy The four criteria of functional adequacy are the following: 1. The theory can be applied to a variety of practice environments and client groups. 2. Empirical indicators have been identified for concepts of the theory. 3. There are published examples of use of the theory in practice. 4. There are published examples of research related to the theory, and the theory has evolved through scholarly inquiry. The criteria have significant overlap and will be analyzed jointly below. The ET theory has been used in many practice environments and with many patient populations. There are multiple published examples of research and use in practice although none have been done with bariatric surgery patients. Of particular relevance to bariatric surgery is the identification of empirical indicators that can be applied consistently. This will lead to better plans of care and more generalizable research results that will impact large numbers of patients. One salient point to note about the evolution of this theory through scholarly inquiry is that one or more of the authors have revised the theory several times. After the theory was used in nursing research, researchers reexamined the theory and built on the new knowledge. This shows the optimal use of a theory and appropriate use of research to support and improve a theory. It has certainly developed through scholarly inquiry about patient transition. Conclusion about utility and appropriateness The theory of ET meets most of the criteria for evaluation of a middle-range theory. This evaluation has demonstrated the use of the theory in nursing practice and research with patients experiencing the transitions associated with bariatric surgery. Application to Research and Practice in Bariatric Surgery Patients Once the utility and appropriateness of ET theory has been established through objective critique, it must be applied to actual research and clinical problems to be useful. A problem Bariatric Nursing, vol. 5, no. 1, 2010 42 that can be addressed both from a research standpoint and in practice is the problem of postoperative weight gain that approaches or exceeds preoperative weight.28 A potential research question that can be addressed using the ET model is: Does preparation and knowledge decrease the incidence of weight gain to preoperative weight in Roux-en-Y gastric bypass patients? A qualitative study might ask, ‘‘What are the lived experiences of Roux-en-Y gastric bypass patients who regained their preoperative weight?’’ Those answers could guide the development of programs to prepare patients to deal with the issues postoperatively or perhaps create a better way of screening patients who are appropriate for the procedure. A quantitative study might hypothesize that a perioperative standardized counseling and education intervention about the pitfalls of postoperative weight gain will result in a 10% weight gain at the 2-year follow-up. The design for the study might be a randomized control group trial of a standardized education and counseling program preoperatively, in addition to counseling in the preoperative waiting period prior to surgery. It may also include patient-driven access to a counseling provider postoperatively while the control group receives usual care. The primary endpoint for the study would be weight gain at the 2-year follow-up visit. A related practice problem might be that a number of postoperative patients who are gaining weight have noticed a sense of loneliness and disconnection at 1 year after surgery when the frequency of office visits decreased, family support has leveled off with acceptance of the patient’s weight loss, and eating patterns have become routine and several friends have ended relations. The model predicts that this outcome pattern is an expectation of the successful transition from obese to normal weight. Although this is an expected outcome, it is a problem for the patient and could impact further weight gain as old eating habits creep back in. Counseling for this patient that incorporates cultural beliefs, personal meaning, and supportive connections is directed toward mastery— operationalized as developing skills in making new connections and developing confidence that obesity had eroded. Nursing therapeutics are a Bariatric Nursing, vol. 5, no. 1, 2010 REEDY AND BLUM ‘‘black box’’ in that they have not been elaborated. Specific research into interventions hypothesized from propositions from the model has not been reported. Using the model and testing hypotheses about interventions with patients experiencing the transitions of bariatric surgery will inform both the care of these patients and the model itself.16 The provider is left then with the opportunity to define the intervention specific to that patient or group of patients based on emerging research and individual strengths. Conclusion Much of how bariatric surgery patients transition and how nurses and other providers assist them is left unresearched. Nurse researchers need to use well-established theories such as ET theory to provide evidence for the care that we provide these patients. In addition, ET can be used jointly by many other healthcare disciplines whose practice includes psychiatry, medicine, sociology, and rehabilitation in the care of these patients. Overall, research needs to be done using this middle-range theory in the care of bariatric surgery patients. Having a theoretical basis for research and practice will make treatment more uniform and research more comparable. This will lead to a more comprehensive and holistic approach to the care of patients who have bariatric surgery. More research will increase our knowledge of transitions and how we, as nurses, can help patients manage their transition and anticipate future transitions. In addition, further qualitative research may help find gaps in the theory and allow us to build upon an already comprehensive theory. Disclosure Statement No competing financial interests exist.
