Brief mindful coloring for stress reduction in nurses working in a Hong Kong hospital during COVID-19 pandemic: A randomized controlled trial.

BACKGROUND: Effective interventions to promote well-being at work are required to reduce the prevalence and consequences of stress and burnout especially during the COVID-19 pandemic. This study determined the effects of mindful coloring on perceived stress levels, mental well-being, burnout, and state and trait mindfulness levels for nurses during COVID-19. METHODS: This was a single-center, two-armed, parallel, superiority, blinded randomized controlled trial. Seventy-seven participants were randomly allocated (by computer-generated sequence) to either mindful coloring (n = 39) or waitlist control groups (n = 38). Twenty-seven nurses in the mindful coloring group and 32 in the control group were included in the full compliance per protocol analysis. The mindful coloring intervention included participants viewing a 3-minutes instructional video and coloring mandalas for at least 5 working days or 100 minutes in total during a 10-day period. Participants in both groups completed the Perceived Stress Scale (total score 0-40), short Warwick-Edinburgh Mental Well-being Scale (total score 7-35), Maslach Burnout Inventory-Human Services Survey for Medical Personnel (3 subscales), Five Facets Mindfulness Questionnaire-Short Form (total score 24-120) and Mindful Attention Awareness Scale-State version (total score 0-30) instruments. The primary outcome was the perceived stress level. RESULTS: Baseline prevalence of moderate to high perceived stress level was high (79.2%). There was a large mindful coloring effect on reducing mean perceived stress levels (Mean difference [MD] in change between groups -3.0, 95% CI: -5.0 to -1.00; Cohen's d = 0.80). Mindful coloring may lead to a small improvement in mental well-being level (P = .08), with an improvement found in the intervention group (MD 0.9, 95% CI 0.0-1.8, P = .04) through enhanced state mindfulness (P < .001). There were no effects on changing burnout subscales or trait mindfulness levels. No adverse reactions were reported. CONCLUSION: Coloring mandalas may be an effective low-cost brief intervention to reduce perceived stress levels through enhancing state mindfulness and it may promote mental well-being. Hospitals may promote or provide mindful coloring as a self-care and stress-relief practice for nurses during their off hours or work breaks.

Effect of preoperative education and ICU tour on patient and family satisfaction and anxiety in the intensive care unit after elective cardiac surgery: a randomised controlled trial.

BACKGROUND: Preoperative education may help participants to psychologically prepare themselves for surgery, but the outcomes of such preparation have rarely been assessed in patients requiring postoperative care in the intensive care unit (ICU) as well as in family members. OBJECTIVE: To assess the effect of a preoperative multifaceted education intervention on patient and family satisfaction levels in the ICU and measures of perioperative patients' anxiety and depression. TRIAL DESIGN: Single-centre, two-armed, parallel, superiority, randomised controlled trial. Healthcare professionals in ICU and outcome assessor were blinded to treatment allocation. PARTICIPANTS: 100 elective coronary artery bypass grafting±valve surgery patients and their family members. INTERVENTIONS: Preoperative education comprising of a video and ICU tour in addition to standard care (treatment), versus standard care (control). OUTCOMES: Patient and family satisfaction levels with ICU using validated PS-ICU23 and FS-ICU24 questionnaires (0-100), respectively; change in perioperative anxiety and depression scores between 1 day presurgery and 3 days postsurgery. RESULTS: Among 100 (50 treatment, 50 control) patients and 98 (49 treatment, 49 control) family members, 94 (48 treatment, 46 control) patients and 94 (47 treatment, 47 control) family members completed the trial. Preoperative education was associated with higher overall patient (mean difference (MD) 6.7, 95% CI 0.2 to 13.2) and family (MD 10.0, 95% CI 3.8 to 16.3) satisfaction scores. There was a weak association between preoperative education and a reduction in patient's anxiety scores over time (MD -1.7, 95% CI -3.5 to 0.0). However, there was no evidence of a treatment effect on patient's depression scores over time (MD -0.6, 95% CI -2.3 to 1.2). CONCLUSION: Providing comprehensive preoperative information about ICU to elective cardiac surgical patients improved patient and family satisfaction levels and may decrease patients' anxiety levels.

Patient and family satisfaction levels in the intensive care unit after elective cardiac surgery: study protocol for a randomised controlled trial of a preoperative patient education intervention.

INTRODUCTION: Patients and their families are understandably anxious about the risk of complications and unfamiliar experiences following cardiac surgery. Providing information about postoperative care in the intensive care unit (ICU) to patients and families may lead to lower anxiety levels, and increased satisfaction with healthcare. The objectives of this study are to evaluate the effectiveness of preoperative patient education provided for patients undergoing elective cardiac surgery. METHODS AND ANALYSIS: 100 patients undergoing elective coronary artery bypass graft, with or without valve replacement surgery, will be recruited into a 2-group, parallel, superiority, double-blinded randomised controlled trial. Participants will be randomised to either preoperative patient education comprising of a video and ICU tour with standard care (intervention) or standard education (control). The primary outcome measures are the satisfaction levels of patients and family members with ICU care and decision-making in the ICU. The secondary outcome measures are patient anxiety and depression levels before and after surgery. ETHICS AND DISSEMINATION: Ethical approval has been obtained from the Joint Chinese University of Hong Kong-New Territories East Cluster Clinical Research Ethics Committee (reference number CREC 2015.308). The findings will be presented at conferences and published in peer-reviewed journals. Study participants will receive a 1-page plain language summary of results.

Randomized controlled trial comparing adaptive-support ventilation with pressure-regulated volume-controlled ventilation with automode in weaning patients after cardiac surgery.

BACKGROUND: Adaptive-support ventilation (ASV) is a minute ventilation-controlled mode governed by a closed-loop algorithm. With ASV, tidal volume and respiratory rate are automatically adjusted to minimize work of breathing. Studies indicate that ventilation in ASV enables more rapid weaning. The authors conducted a randomized controlled trial to determine whether ventilation in ASV results in a shorter time to extubation than pressure-regulated volume-controlled ventilation with automode (PRVCa) after cardiac surgery. METHODS: Fifty patients were randomly assigned to ASV or PRVCa after elective coronary artery bypass grafting. Respiratory weaning progressed through three phases: phase 1 (controlled ventilation), phase 2 (assisted ventilation), and phase 3 (T-piece trial), followed by extubation. The primary outcome was duration of intubation (sum of phases 1-3). Secondary outcomes were duration of mechanical ventilation (sum of phases 1 and 2), number of arterial blood gas samples, and manual ventilator setting changes made before extubation. RESULTS: Forty-eight patients completed the study. The median duration of intubation was significantly shorter in the ASV group than in the PRVCa group (300 [205-365] vs. 540 [462-580] min; P < 0.05). This difference was due to a reduction in the duration of mechanical ventilation (165 [120-195] vs. 480 [360-510] min; P < 0.05). There were no significant differences between the ASV and PRVCa groups in the number of arterial blood gas samples taken or manual ventilator setting changes made. CONCLUSIONS: ASV is associated with earlier extubation, without an increase in clinician intervention, when compared with PRVCa in patients undergoing uncomplicated cardiac surgery.

Expanding ICU facilities in an epidemic: recommendations based on experience from the SARS epidemic in Hong Kong and Singapore.

Epidemics have the potential to severely strain intensive care resources and may require an increase in intensive care capability. Few intensivists have direct experience of rapidly expanding intensive care services in response to an epidemic. This contribution presents the recommendations of an expert group from Hong Kong and Singapore who had direct experience of expanding intensive care services in response to the epidemic of severe acute respiratory syndrome. These recommendations cover training, infection control, staffing, communication and ethical issues. The issue of what equipment to purchase is not addressed. Early preparations should include fit testing of negative pressure respirators, training of reserve staff, sourcing of material for physical modifications to the ICU, development of infection control policies and training programmes, and discussion of triage and quarantine issues.
