What does the answer mean? A qualitative study of how palliative cancer patients interpret and respond to the Edmonton Symptom Assessment System

The Edmonton Symptom Assessment System (ESAS) is a well-known self-reporting tool for symptom assessment in palliative care. Research has shown that patients experience difficulties in the scoring and interpretation, which may lead to suboptimal treatment. The aims were to examine how palliative care cancer patients interpreted and responded to the ESAS. Eleven patients (3 F/8 M), median age 65 (34–95) with mixed diagnoses were interviewed by means of cognitive interviewing, immediately after having completed the ESAS. The highest mean scores were found with tiredness (6.3) and oral dryness (5.7). The results showed that sources of error were related to interpretation of symptoms and differences in the understanding and use of the response format. The depression and anxiety symptoms were perceived as difficult to interpret, while the appetite item was particularly prone to misunderstandings. Contextual factors, such as mood and time of the day, influenced the answers. Lack of information and feedback from staff influenced the scores. Some patients stated that they scored at random because they did not understand why and how the ESAS was used. The patients’ interpretation must be considered in order to minimize errors. The ESAS should always be reviewed with the patients after completion to improve symptom management, thereby strengthening the usability of the ESAS.

Preoperative predictors of adherence to dietary and physical activity recommendations and weight loss one year after surgery

BACKGROUND Weight loss and weight loss maintenance vary considerably between patients after bariatric surgery. Postoperative weight gain has partially been explained by lack of adherence to postoperative dietary and physical activity recommendations. However, little is known about factors related to postoperative adherence. OBJECTIVES The aim of this study was to examine psychological, behavioral, and demographic predictors of adherence to behavior recommendations and weight loss 1 year after bariatric surgery. SETTING Oslo University Hospital. METHODS In a prospective cohort study, 230 patients who underwent Roux-en-Y gastric bypass were recruited from Oslo University hospital from 2011 to 2013. They completed a comprehensive questionnaire before and 1 year after surgery. Weight was measured preoperatively, on the day of surgery, and 1-year postoperatively. RESULTS Mean body mass index was 44.9 kg/m(2) (standard deviation [SD] = 6.0) preoperatively and 30.6 kg/m(2) (SD = 5.2) 1 year after surgery. Patients lost on average 29.2 % (SD = 8.2) of their initial weight. Predictors of dietary adherence were years with dieting experience, readiness to limit food intake, and night eating tendency. Preoperative physical activity and planning predicted postoperative physical activity whereas predictors of weight loss were higher frequency of snacking preoperatively, greater past weight loss, and lower age. CONCLUSION Several preoperative psychological predictors were related to postoperative adherence to dietary and physical activity recommendations but were not associated with weight loss. Interventions targeting psychological factors facilitating behavior change during the initial postoperative phase are recommended as this might improve long-term outcomes.

Psychosocial characteristics associated with symptom perception 1 year after gastric bypass surgery—a prospective study☆

BACKGROUND The experience of symptoms after bariatric surgery, such as pain, dumping, and fatigue, may affect behavior, quality of life, and the need for healthcare consultations. Attention to and interpretation of symptoms are influenced by psychological and contextual factors. Prospective studies of psychological factors predicting physical symptom perception after bariatric surgery are scarce. OBJECTIVES To explore associations of preoperative negative affect and history of stressful and traumatic events with frequency and intensity of self-reported symptoms 1 year after Roux-en-Y gastric bypass (RYGB). SETTING University hospital. METHODS Questionnaire data were collected before and 1 year after RYGB from 230 patients. Negative affect and stressful events were measured preoperatively. The participants reported the number and impact of various physical symptoms postoperatively. RESULTS The most common symptoms reported to have a high impact on behavior were fatigue (32.8%) and dumping (28.4%). Reporting more symptoms was associated with preoperative anxiety (r = .22, P = .001) and the number of stressful life events (r = .21, P = .002). Participants with a probable preoperative anxiety disorder reported a higher impact of fatigue, pain, dumping, and diarrhea after surgery, while those with a probable mood disorder and a history of traumatic sexual/violent events reported a higher impact of dumping. CONCLUSION Preoperative anxiety symptoms and stressful experiences were associated with a higher perceived impact of symptoms, such as dumping, fatigue, and pain after RYGB. The evaluation of psychological characteristics associated with symptom perception may be relevant when managing symptoms that are not responsive to other treatment measures.
