Considering the known challenges facing newly graduated nurses, there are possibilities to implement preventive actions. The aim of the current study was to evaluate the effects of a preventive intervention among newly graduated nurses, supporting proactive strategies for sleep and recuperation in relation to work related stress and shift work.
Approximately 20% of all Swedish nurses experiences very high levels of burnout symptoms at some point during the first years of practice. Many factors are likely to be involved, and when developing methods to facilitate the nurse's transition from education into working life, a variety of stressors at both the organisational and individual level have to be considered. Previously, incomplete recovery has been suggested to mediate the relation between stressful working conditions and health impairment. For many, starting working as a nurse also means an introduction to shiftwork, which inevitably affects opportunities for sleep and recuperation due to interference with the circadian and homeostatic regulation of sleep. Given the vital role of sleep and recovery in the relationship between stress and development of impaired health, effective strategies for sleep and recuperation are hypothesised to be crucial in preventing the development of stress-related symptoms among nurses. In addition, lack of sleep and recuperation results in fatigue, which is a major safety hazard threatening patient safety. The aim of the current study was to evaluate a preventive intervention for new nurses, supporting strategies for sleep and recuperation in relation to work related stress and shift work.
Recruitment Newly graduated nurses were recruited at five Swedish hospitals. The recruitment was done via the introduction programmes, except from at one of the hospitals (which did not have such a programme) where the nurses instead were recruited via the different clinics. In total the intervention was implemented in eight different cohorts during 2017 and 2018. Approximately 462 newly graduated nurses were invited to participate in the study and 207 joined and answered the baseline questionnaire (45%).
Design The participants were randomly assigned to intervention and control groups. The participants were followed with questionnaires Participants were followed with either questionnaires or questionnaires + intesive measures using diary, actigraphy and cognitive tests. Questionnaires were filled in before the intervention (baseline), one month after the intervention (post), and at six months after the intervention (follow-up). The intensive measure was conducted at baseline and post intervention.
The participants also got a short questionnaire to fill out at the start of session two and three, and two weeks after session three, in which they filled out which strategies they had used during the last couple of weeks. After the last session, participants were asked to evaluate the intervention using a short questionnaire.
The intervention The intervention was a preventive programme focusing on beneficial strategies for sleep and recuperation in relation to work stress and shift work. The programme included three 2.5 hours-group sessions every second week. The sessions were taking place at work during working hours. The intervention was based on knowledge from research on sleep, stress and work hours, as well as on cognitive behavioural therapy (CBT) techniques for sleep and stress management modified for shift workers. The regulation of sleep and wakefulness was explained by the three factors: 1) circadian rhythm, 2) homeostatic process, and 3) stress, referred to as the sleep formula. How these factors interacts with irregular work hours was explained. Participants were encouraged to reflect on their daily habits related to sleep and recovery. Also, a CBT-model for analysing behaviours in stressful work situations were used in order to encourage participants to reflect on their usual behaviours and possible alternatives. As homework between sessions, the participants were encouraged to try possibly beneficial strategies for sleep and recuperation. The participants got written material, after every session, covering the content of the session. In addition, the participants got access to an adapted version of the biomathematical model (ArturNurse) to give participants an estimation of expected sleep lengths and fatigue levels together with tips of possible strategies to optimise sleep in relation to different shifts.

| Bädda för Kvalitet | Behavioral | A group-administered preventive programme focusing on beneficial strategies for sleep and recuperation, in relation to work related stress and shift work. The intervention was based on knowledge from previous research on sleep, stress and work hours, as well as on cognitive behavioural therapy (CBT) techniques for sleep and stress management, modified for shift workers. Participants were encouraged to discuss and reflect on personal habits related to sleep and recovery. As homework between sessions, the participants were encouraged to try possibly beneficial strategies for sleep and recuperation. All participants got written material covering the content of the session, during each sessions. In addition, an adapted version of a biomathematical model ("ArturNurse") was used to give participants an estimation of expected sleep lengths and fatigue levels together with tips of possible strategies to optimise sleep in relation to different shifts. |
| Measure | Description | Time Frame |
|---|---|---|
| Change in insomnia symptoms (subjective measure) | Insomnia Severity Index (ISI) which consists of 7 questions related to sleep e.g. "How satisfied are you with your current sleep pattern?" (0 = very satisfied, 4 = very dissatisfied). The total score is summarised with a minimum score 0, maximum score 28. Higher scores indicate more sleep problems. | In order to detect change measures were made at baseline, 4 weeks after the intervention and 6 months after the intervention. |
| Change in sleep quality (subjective measure) | Karolinska Sleep Questionnaire (KSQ) from which a sleep quality index was formed based on four questions e.g. "Have you had problems falling asleep the past month"? etc : Minimum score 1, maximum score 6. Lower scores indicate worse sleep quality. | In order to detect change measures were made at baseline, 4 weeks after the intervention and 6 months after the intervention. |
| Change in Dysfunctional beliefs and attitudes about sleep (subjective measure) | Dysfunctional Beliefs and Attitudes about Sleep (DBAS) consists of 10 statements regarding beliefs and attitudes to sleep e.g. "I am concerned that chronic insomnia may have serious consequences on my physical health"; "When I have trouble sleeping, I should stay in bed and try harder" (strongly agree - strongly disagree): Minimum score 0, maximum score 10. Higher scores indicate more dysfunctional sleep-related cognitions. | In order to detect change measures were made at baseline, 4 weeks after the intervention and 6 months after the intervention. |
| Change in sleep (subjective measure) | Karolinska Sleep Diary (KSD). KSD includes bedtime; time of awakening; sleep latency (the time it takes to fall asleep); feelings of worry and stress at bedtime (1 very worried/aroused - 5 very calm/relaxed); and the following questions: Did you have difficulties falling asleep? (1 = very; 5 = not at all) How did you sleep? (1 = very badly; 5 = very good); Did you have a restless sleep? (1 = very much so; 5 = not at all); Did you wake up very early without being able to fall asleep? (1 = much too early; 5 = no). These four latter questions constitutes a sleep quality index, minimum score 1, maximum score 5: Lower scores indicate worse sleep quality. |
| Measure | Description | Time Frame |
