Factors affecting fistula failure in patients on chronic hemodialysis: a population-based case-control study.

BACKGROUND: With advancement of hemodialysis (HD) technique, late fistula failure (LFF) remains a problem significantly affecting life quality of patients. We attempt to identify factors affecting LFF in patients on chronic HD in Taiwan from the National Health Insurance Research Database. METHODS: This case-control study enrolled patients over 18 years old and who received regular HD for more than 3 months. LFF was defined as the first fistula failure episode beyond 3 months of chronic HD. We analyzed characteristics, comorbidities and medicine and investigated the association factors of LFF by logistic regression model. A trend test was conducted for risk in different provider levels. Sensitivity tests were conducted to test consistency. RESULTS: Of 1558 patients recruited, 772 (49.6%) were identified as LFF cases and 786 were identified as controls. The data showed that patients with diabetes mellitus (DM) had 42% increased rate of LFF. Patients receiving more than 10 HD sessions per month had a 90% increased rate of LFF; patients receiving chronic HD in private clinics had a 49% reduction rate of LFF. There were no significant differences in age, dialysis frequency, and comorbidities among different provider levels. There was a significant trend of risk reduction of the event from medical centers, regional hospitals, district hospitals, to private clinics. The sensitivity tests revealed similar results. CONCLUSIONS: The factors associated with LFF include DM and receiving more HD sessions; on the contrary, receiving HD in private clinics is associated with less risk of LFF.

Effectiveness of green tea mouthwash for improving oral health status in oral cancer patients: A single-blind randomized controlled trial.

BACKGROUND: Painful oral mucositis or trismus, caused by cancer therapy, reduces patients' willingness to maintain basic oral hygiene and eventually results in a poor oral health status. Using mouth rinses and cleaning the tongue are popular ways to improve the oral health status. OBJECTIVES: To evaluate the effectiveness of green tea mouthwash for improving the oral health status in oral cancer patients undergoing cancer treatment. DESIGN: This was a prospective, single-blind, randomized, controlled trial. SETTINGS: Patients were recruited from a major regional teaching hospital that provides specialist cancer care services in Chia-Yi, Taiwan, from July 2018 to June 2020. PARTICIPANTS: A total of 63 patients met the following criteria: > 20 years old; newly diagnosed with oral cancer by a physician; treated with oral surgery within one month prior; and completion of follow-up, with or without chemotherapy or radiation therapy. The exclusion criteria were mental illness; an acute and severe illness; complete edentulism; and inability to open the mouth more than 1 cm. METHODS: Patients were randomly assigned to 2 groups: the mouthwash with green tea (intervention) group or the tap water (control) group. After each teeth-brushing procedure, those in the intervention group rinsed the mouth with 100 ml of a green tea solution for 60 seconds, and those in the control group rinsed the mouth with 100 ml of tap water for 60 seconds. The primary outcome was the oral health status, which was evaluated according to the Oral Assessment Guide and measured at baseline and at every monthly outpatient follow-up until six months by the same nurse. RESULTS: There were 31 subjects in the intervention group and 30 subjects in the control group in the final analysis. The results of t-test showed that compared with baseline, the improvement in the oral health status in the intervention group was significantly better than that in the control group at 4 months after the intervention began. At 4 to 6 months after the intervention began, the oral health status score in the intervention group significantly decreased, by 1.71, 2.97 and 2.93 points, respectively, compared with that in the control group. CONCLUSIONS: The oral health status can be improved and maintained for a long time with the continuous use of green tea mouthwash. Green tea mouthwash is a simple, natural, effective and safe intervention that should be recognized as a nonpharmacological treatment option for protecting the oral mucosa.

A Profile of Novice and Senior Nurses' Communication Patterns during the Transition to Practice Period: An Application of the Roter Interaction Analysis System.

Novice nurses' successful transition to practice is impacted by their interactions with senior nurses. Ensuring that novice nurses are adequately supported during their transition to practice has wide-ranging and significant implications. The aim of this study is to explore the communication patterns between novice and senior nurses by applying an interaction analysis technique. Trimonthly onboarding evaluations between novice and senior nurses were recorded. The Roter Interaction Analysis System was adapted and deployed to identify communication patterns. In total, twenty-two interactions were analyzed. Senior nurses spoke more (64.5%). Task-focused exchange was predominant amongst senior (79.7%) and novice (59.5%) nurses. Senior nurses' talk was concentrated in clusters of information-giving (45%) and advice or instructions (17.2%), while emotional expression (1.4%) and social talk (0.4%) were rare. Novice nurses' talk was concentrated in clusters-information giving (57%) and positive talk (39.5%). The communication patterns between senior and novice nurses during the onboarding period indicate aspects of novice nurse transition that could be addressed, such as encouraging novice nurses to use these interactions to communicate more, or emphasizing the importance of social talk. These insights can be used to inform mentorship and preceptorship training to ensure that senior nurses are able to adequately support novice nurses through all parts of the transition to practice period.
