Brief Summary

Background: Our pilot study showed that the prevalence of headaches is 43.5% among nurses working in critical care units in a medical center in Taiwan. In the pilot study, 70% nurses with headache are willing to participate in this intervention study with essential oil. The effect of aromatherapy (essential oils through smelling) is convenient for nurses but still lacks strong evidences regarding relieving headaches. Purpose: Thus, in this intervention study, we will examine whether the necklace with essential oil can (1) improve the pain intensity and frequency of headache; (2) reduce the score of headache disability inventory (HDI) and (3) improve the nurses' quality of life and care quality. Method: Cluster randomized control trial from 16 critical care units at a medical center in Taiwan. The International Classification of Headache Disorders (ICHD, 3rd edition) was used to identify the headache type as "migraine" or "tension-type headache." We will recruit the nurses from 16 critical care units who has migraine or tension-type headache and cluster random assign (according to the ward unit) to group A and B. The intervention of necklace with essential oil will use to compare with the other group. According to power analysis and possible attrition rate, 103 nurses will be recruited. All participants will be asked to complete self-administrated questionnaires, including headache information questions, headache disability inventory (HDI), Migraine Specific Quality of Life Questionnaire version 2.1 (MSQv2.1), Copenhagen burnout inventory (CBI), Service Quality Scale (SERVQUAL), Intention to leave inventory (ITL), Depression, Anxiety and Stress Scale (DASS-21), Tasks Undone-13 (TU-13). The quantitative data will analyze by percentage, mean, standard deviation, chi-square test, and generalized estimating equation (GEE). Expected outcomes and future implications: The aromatherapy (necklace with essential oil) can reduce the pain intensity, frequency, disability of headaches, as well as enhance nurses' quality of life and care quality.

Outcome Measures

Primary Outcomes (9)

  • Changes of Headache Diary

    The Headache Diary measured the participants to record the condition of headache with 12 items. The investigators will analyzed the intensity, frequency, duration, location, quality, symptoms, time and medicine use, and the duration (hours) of wearing the necklace with essential oil. At the meanwhile, we also collect the perceived busy level of the work day to control the association between the workload and headache. Thus, the participants have to write the diary everyday for 9 weeks and we will remind them by the text. The diary also mixes in the short-form McGill pain questionnaire (SF-MPQ) that was developed by Melzack in 1975 and revised in 1987 and it developed from the different type of headache depending on the pain intensity and quality (Melzack, 1975). The investigators simplified the contents and transfer to code so that the participants can easily fill out the diary every day.

    The participants will be assessed among pre-test week 1 (T1) and persistent to fill out the headache diary every day for 9 weeks (totally 63 days)

  • Changes of Headache Disability Inventory (HDI)

    The Headache Disability Inventory (HDI) measured the burden caused by chronic headaches with 27 items (French et al., 2000). Each item scored from 1 to 3 (1= always happened; 3 = never happened). The higher score indicated the higher impacts of headache on emotional function and daily life.

    The participants will be assessed among pre-test week 1 (T1), week 5 (T2) and week 10 (T3)

  • Changes of Migraine Specific Quality of Life Questionnaire version 2.1 (MSQv2.1)

    The Migraine Specific Quality of Life Questionnaire version 2.1 (MSQv2.1) measured the quality of life of migraine and headache patients, including the function, limitation, burden and impacts of the migraine with 14 items (Bagley et al., 2011). Each item was scored from 1 to 6 (1= always happened; 6 = never happened). The higher score indicated the higher impact of headache on quality of life. Cronbach's alphas are 0.79-0.85 (Bagley et al., 2011).

    The participants will be assessed among pre-test week 1 (T1), week 5 (T2) and week 10 (T3)

  • Changes of Copenhagen Burnout Inventory (CBI)

    The Copenhagen Burnout Inventory (CBI) measured occupational burnout with 21 items (Yah et al, 2008). The questionnaire is including subscales-personal burnout, work-related burnout, client-related burnout, and over-commitment to work. Each item scored from 1 to 5 (1= never happened, 5 = always happened). The higher scores indicated the stronger work burnout. Cronbach's alphas are 0.89-0.95 (Yang et al, 2014).

    The participants will be assessed among pre-test week 1 (T1), week 5 (T2) and week 10 (T3)

  • Changes of Service Quality Scale (SERVQUAL)

    The Service Quality Scale (SERVQUAL) measured the care quality of nurses in the hospital, including the four domains: trustworthiness, responsiveness, promise and empathy with 28 Likert's scale items (Teng et al., 2007). Each item scored from 1 to 5 (1= strongly disagree; 5 = strongly agree). The higher score indicated the higher confidence on their care quality.

    The participants will be assessed among pre-test week 1 (T1), week 5 (T2) and week 10 (T3)

  • Changes of Intention to Leave Inventory (ITL)

    The Intention to Leave Inventory (ITL) measured the intention to leave the organization and their future career plan with 7 Likert's scale items (Teng, Shyu, \& Chang, 2007). Each item scored from 1 to 7 (1= strongly disagree; 7 = strongly agree). The higher score indicated the higher strongly intention to leave the organization.

    The participants will be assessed among pre-test week 1 (T1), week 5 (T2) and week 10 (T3)

  • Changes of Depression, Anxiety and Stress Scale (DASS-21)

    The Depression, Anxiety and Stress Scale (DASS-21) measured the level of depression, anxiety and stress during the past week recently by 21 items (Moussa, 2001). Each item scored from 1 to 4 (1= strongly disagree; 4 = strongly agree). The higher score indicated more frequency of feeling depression, anxiety and stress (Lovibond \& Lovibond, 2004). Cronbach's alphas were 0.87-0.94 (Black et al., 2015).

    The participants will be assessed among pre-test week 1 (T1), week 5 (T2) and week 10 (T3)

  • Demographic and Headache Information Questionnaire

    The Demographic Questionnaire included the birth date, sex, marital status, amenorrhea, education, unit, working years and rank. Although the necklace's colors are distributed randomly, considering the color may also affect the participants 'mood or the condition of headache, therefore, The investigators also survey the subject's preference of color to control the potential effect. The Headache Information Questionnaire was modified from the International Classification of Headache Disorders (ICHD, 3rd edition) to identify the headache type as "migraine" or "tension-type headache. Items included pain intensity, frequency, onset of the times, symptoms, locations, etc.

    The participants will be assessed at pre-test week 1 (T1)

  • Tasks Undone-13

    The tasks undone-13 measured the missed care with 13 items (Aiken et al; Ball et al., 2013; Schubert, 2007). Each item scored from 0 to 1 (0 = left done, 1 = done and NA= not applicable) The higher score indicated the volume of care left done. Cronbach's alpha = 0.73 (Lucero et al., 2009) and content validity index is 0.70-0.91 (Squires et al., 2013)。

    The participants will be assessed among pre-test week 1 (T1), week 5 (T2) and week 10 (T3)
