Opportunities for Interactive Communication in Mechanically Ventilated Critically Ill Patients: A Video-Based Observational Study.

Background: Mechanically ventilated critically ill patients need the opportunity to communicate their physical and psychosocial concerns to nurses. However, these patients face the unique problem of lacking even the opportunity to communicate. Aims: The study aimed to describe the characteristics of communication opportunities for critically ill mechanically ventilated patients. Methods: The study was designed as a video-based descriptive observational study. Participants included seven mechanically ventilated critically ill patients at the intensive care unit, coronary care unit, or high care unit who were conscious and seven registered nurses (seven pairs). Videos were recorded continuously from 8 am to 4 pm, and the footage was then descriptively analyzed. Data collection took place between July 2019 and June 2020. Results: The total recording time was 668.0 minutes. Of these 668.0 minutes, nurses stayed in the Conversation Area of the Patient for 279.6 minutes, and of these 279.6 minutes, two-way face-to-face communication between nurse and patient occurred for 78.0 minutes. Of these 78.0 minutes, communications were started by nurses for 47.2 minutes (174 scenes) and by patients for 24.2 minutes (36 scenes). The patient-started two-way communication scenes included 37 instances of Patient-Intentional-Action that triggered the start of communication. Actions using the upper limbs were observed in 20 instances and represented the most frequently used body part. The head/face, lower limbs, or trunk were also used in some of the actions. Gestures were the most commonly used action type (14 instances). Other types included lip movement, grimace, leg flex/extension, and cough. Conclusions: We found that nurses tended to start communication more frequently than patients did and that patients demonstrated Patient-Intentional-Action with a variety of actions using various body parts. Communication opportunities for patients were created when nurses took the initiative to start communication or when they noticed and responded to the Patient-Intentional-Action. Our findings demonstrate that nurses need to recognize and always respond to Patient-Intentional-Action and to take the initiative in communicating rather than waiting for the patient to do so.

Identifying periodicity in nurse call occurrence: Analysing nurse call logs to obtain information for data-based nursing management.

AIM: To verify our hypothesis that 'there is periodicity in nurse call occurrence'. BACKGROUND: It is difficult to plan nursing management because nursing tasks can vary widely, seemingly at random. One of the most useful pieces of information for decision-making is periodicity. If periodicity is present, it should be possible to predict the occurrence of tasks and make preventive strategies. In this study, we focused on the nurse call, which plays an important role in nursing practice. METHOD: We used nurse call logs that accumulated automatically when patients pushed the button. Data were obtained from 1 January 2014 to 30 September 2017 (1,369 days) in a university hospital. The total number was 5,982,935. Periodicity was verified by the autocorrelation function. RESULTS: The value of the autocorrelation function increased regularly, which demonstrates there was periodicity in nurse call occurrence. CONCLUSION: Our hypothesis was accepted. The presence of periodicity indicates that nurse call occurrence is not a random event but has a pattern. IMPLICATIONS FOR NURSING MANAGEMENT: If we can identify patterns such as the time that nurse calls frequently occur, managers can implement two strategies: one, assigning more nurses and two, moving tasks other than nurse calls to another time.

A Large Difference in Dose Timing of Basal Insulin Introduces Risk of Hypoglycemia and Overweight: A Cross-Sectional Study.

INTRODUCTION: Basal insulin should be injected at the same time each day, but people with diabetes sometimes mistime their injections. It is not known whether irregular daily dose timing affects diabetes-related factors. We report here our evaluation of the effects of deviations from a regular dosing schedule on glycemic control and hypoglycemia on patients treated with long-acting insulin (insulin glargine U100). We also consider the effects of ultra-long-acting insulin (insulin degludec) in this context. METHODS: Nineteen individuals with type 1 diabetes and 58 with type 2 diabetes were enrolled. Demographic data on all participants were retrieved from their medical records. Variation in dose timing was determined as the difference between the time of the earliest mistimed dose and the time of the latest mistimed dose, for each participant, over a 2-week period. All participants completed the Summary of Diabetes Self-Care Activities questionnaire, Problem Areas in Diabetes scale and 5-Item World Health Organization Well-being Index. Glargine U100 was switched to degludec in those individuals with type 2 diabetes who achieved inadequate glycemic control or suffered from frequent hypoglycemic episodes or who required two injections per day, and changes in hemoglobin A1c level and frequency of hypoglycemic episodes during the 12-week period were compared. RESULTS: A greater difference in dose timing was related to a higher frequency of hypoglycemic episodes and overweight in persons with type 2 diabetes. Smoking, drinking and living alone were independently associated with a greater difference in dose timing. Insulin degludec decreased the frequency of hypoglycemia and improved glycemic control in participants whose dose mistiming was >120 min. CONCLUSION: Fixed dose timing should be employed for basal insulin, as a larger difference in dose timing worsens diabetes-related factors. Insulin degludec improved glycemic control and lowered the hypoglycemia rate in persons with more irregular dose timing.

Effects of tryptophan-rich breakfast and light exposure during the daytime on melatonin secretion at night.

BACKGROUND: The purpose of the present study is to investigate effects of tryptophan intake and light exposure on melatonin secretion and sleep by modifying tryptophan ingestion at breakfast and light exposure during the daytime, and measuring sleep quality (by using actigraphy and the OSA sleep inventory) and melatonin secretion at night. METHODS: Thirty three male University students (mean ± SD age: 22 ± 3.1 years) completed the experiments lasting 5 days and 4 nights. The subjects were randomly divided into four groups: Poor*Dim (n = 10), meaning a tryptophan-poor breakfast (55 mg/meal) in the morning and dim light environment (<50 lx) during the daytime; Rich*Dim (n = 7), tryptophan-rich breakfast (476 mg/meal) and dim light environment; Poor*Bright (n = 9), tryptophan-poor breakfast and bright light environment (>5,000 lx); and Rich*Bright (n = 7), tryptophan-rich breakfast and bright light. RESULTS: Saliva melatonin concentrations on the fourth day were significantly lower than on the first day in the Poor*Dim group, whereas they were higher on the fourth day in the Rich*Bright group. Creatinine-adjusted melatonin in urine showed the same direction as saliva melatonin concentrations. These results indicate that the combination of a tryptophan-rich breakfast and bright light exposure during the daytime could promote melatonin secretion at night; further, the observations that the Rich*Bright group had higher melatonin concentrations than the Rich*Dim group, despite no significant differences being observed between the Poor*Dim and Rich*Dim groups nor the Poor*Bright and Rich*Bright groups, suggest that bright light exposure in the daytime is an important contributor to raised melatonin levels in the evening. CONCLUSIONS: This study is the first to report the quantitative effects of changed tryptophan intake at breakfast combined with daytime light exposure on melatonin secretion and sleep quality. Evening saliva melatonin secretion changed significantly and indicated that a tryptophan-rich breakfast and bright light exposure during the daytime promoted melatonin secretion at this time.
