RESUMO
OBJECTIVES: Previous reviews have concluded that interventions including psychoeducation are effective in preventing relapse in bipolar disorder, but the efficacy of psychoeducation itself has not been systematically reviewed. Our aim was to evaluate the efficacy of psychoeducation for bipolar disorder in preventing relapse and other outcomes, and to identify factors that relate to clinical outcomes. METHODS: We employed the systematic review of randomized controlled trials of psychoeducation in participants with bipolar disorder not in an acute illness episode, compared with treatment-as-usual, and placebo or active interventions. Pooled odds ratios (ORs) for non-relapse into any episode, mania/hypomania, and depression were calculated using an intent-to-treat (ITT) analysis, assigning dropouts to relapse, with a sensitivity analysis in which dropouts were assigned to non-relapse (optimistic ITT). RESULTS: Sixteen studies were included, eight of which provided data on relapse. Although heterogeneity in the data warrants caution, psychoeducation appeared to be effective in preventing any relapse [n = 7; OR: 1.98-2.75; number needed to treat (NNT): 5-7, depending on the method of analysis] and manic/hypomanic relapse (n = 8; OR: 1.68-2.52; NNT: 6-8), but not depressive relapse. Group, but not individually, delivered interventions were effective against both poles of relapse; the duration of follow-up and hours of therapy explained some of the heterogeneity. Psychoeducation improved medication adherence and short-term knowledge about medication. No consistent effects on mood symptoms, quality of life, or functioning were found. CONCLUSIONS: Group psychoeducation appears to be effective in preventing relapse in bipolar disorder, with less evidence for individually delivered interventions. Better understanding of mediating mechanisms is needed to optimize efficacy and personalize treatment.

OBJECTIVE: To describe the use of non-invasive ventilation (NIV) in adults presenting with status asthmaticus to Middlemore Hospital Critical Care Complex (CCC, South Auckland, New Zealand) from 2000 to 2015. METHOD: Retrospective review of all adult asthma admissions to the Hospital CCC between 2000 and 2015. Demographic, physiological, treatment data and blood gas results were recorded. RESULTS: There were 265 asthma admissions to Middlemore Hospital CCC during the study period. The median age was 34 years; 64% were female. NIV was used in 186 admissions, of which eight went on to require intubation and invasive mechanical ventilation (IMV). Twenty-three other admissions received IMV without a trial of NIV and a further 58 were managed with medical care only. The average pH for all admissions was 7.23 and the IMV group had an average pH of 6.99. Forty-five admissions presented with a Glasgow Coma Scale (GCS) score of ≤10. Twenty-five of these were managed with NIV with only one requiring subsequent intubation. The mean duration of NIV in this group was 5 h (range 1-17 h) with a mean ICU and hospital length of stay of 17 h and 3.5 days, respectively. All patients in this group effectively lowered the pCO2 over a 2 h period with NIV having an average drop of 5.9 kPa and IMV 3.4 kPa. CONCLUSION: The use of NIV appears to be safe and effective in patients with severe asthma, including selected patients with an altered level of consciousness. NIV was well tolerated with a low need for subsequent intubation.
