perspective. Factors important to patients for surgical success after stone surgery have not been explored. We looked to determine patient factors important for surgical success, changes in such factors before and after surgery, and the quantity of criteria reduction for surgical success.METHODS: Established stone patients scheduled for renal stone surgery completed a modified patient centered outcome questionnaire (PCOQ) before and 6-8 weeks after surgery. The modified PCOQ evaluated multiple domains including: pain, hematuria, urinary symptoms, infections, emotional distress, and activity of daily living impairment. Patients rated their current, desired, and expected levels within each domain as well as levels for surgical success. Patient were also queried on the importance of being stone free.RESULTS: Our cohort consisted of 59 patients, 68% female with a mean age of 54.9 years. Prior stone history was reported in 69% and 51% underwent prior stone surgery. Ureteroscopy was performed in 58% of patients and 42% underwent percutaneous nephrolithotomy. 62% of patients were stone free after surgery based on follow up renal ultrasound. 64% of patients rated pain as the most important factor for surgical success, while 13% rated being stone free as most important. The top 3 reported factors for success were pain (85%), activity of daily living impairment (44%) and stone free status (29%). Subjects who rated pain as their most important factor, on average, required a 78% reduction in symptoms for surgery to be considered successful. There was a statistically significant decrease in mean levels of symptoms for all domains after surgery (p < 0.0001).CONCLUSIONS: Success after stone surgery has long been synonymous with stone free rates, but the paradigm may be shifting. Definitions for surgical success for stone disease should now incorporate the patient perspective. Within our cohort, patients' definitions of success were varied and revolved around pain and symptom resolution with daily activities. Patients not only seek relief from symptoms, but large reductions are required for surgery to be considered successful. However, most patients did not require complete resolution of symptoms to consider treatment a success. Provider insight into individual patient's success criteria may help with shared decision making, preoperative counseling and postoperative patient satisfaction.
Discussing and conducting research on end-of-life issues is often difficult. However, it is important to initiate a dialogue about various topics surrounding death and dying. This paper looks at the available scientific literature relating to oxygen use at the end of life, describes associated attitudes and beliefs, and presents some brief examples of institutional practices. The aim is to stimulate thoughtful reflection and encourage research on this important topic. There is limited research regarding oxygen use at the end of life, and many questions remain. Despite the difficulty with research in this area, there is a need to expand the data and awareness in this field. Several authors have questioned the use of oxygen in end-of-life care, and the evidence that oxygen use may not always be indicated is growing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
