RESUMEN
Introduction: Mental health triage is a new nursing practice concept that is less studied and defined, especially among Iranian nurses. Therefore, this study aimed to explain the concept of mental health triage from the perspective of psychiatric emergency department (ED) nurses. Methods: This qualitative study collected data using semi-structured interviews with psychiatric ED nurses. Sampling was purposive and continued until data saturation. Analysis was conducted using conventional content analysis, as described in Griesheim and Landman approach. Results: 15 psychiatric ED nurses with the mean age of 35.13 ± 8.44 years were interviewed (60% male). Finally, two themes, five categories, and 16 sub-categories emerged from data analysis. Two themes emerged, including mental health triage meaning and mental health triage structure. The former included two categories of the nature and characteristics of mental health triage, and the latter consisted of three categories of mental state exploration from surface to depth, safety control measures, and the degree of emergency. According to the "degree of emergency" category, nurses could not make triage decisions based on their perceptions in an acceptable way. Conclusion: Psychiatric ED nurses have an appropriate understanding of mental health triage meaning. However, according to these nurses, its structure is associated with shortcomings that limit the provision of mental health triage services and reduce their quality.
RESUMEN
To assess the efficacy alternative medicine in the treatment of nausea and vomiting of pregnancy (NVP), three major databases of PubMed, Cochrane Library and Scopus were systematically searched since inception until January 14 2019 to investigate the effects of herbal medicines on NVD. The quality assessment of studies was performed according to Jadad scale. All studies showed that ginger had a positive effect on nausea in pregnant women. Unlike others studies, one study reported that ginger was not beneficial to the treatment of vomiting. Herbal medicines such as matricaria chamomilla, elettaria cardamomum, pomegranate and spearmint syrup, lemon provide safe and effective medical alternatives for treating pregnant women with mild to moderate NVD. The results suggested that ginger were more effective than vitamin B, but at the dose of 35-500 mg ginger, vitamin B6 and ginger had identical effect. However, over a longer treatment period (60 days), vitamin B6 was proved to be more effective than ginger. The same effect was observed in the comparison of quince and vitamin B6 as well as ginger and doxylamine plus pyridoxine. Mentha did not generated a positive effect on nausea and vomiting. However, this finding should be considered in the light of the above limitations.IMPACT STATEMENTWhat is already known on the subject? Previous systematic reviews have shown the superiority of ginger over the placebo. Lemon, chamomile and Mentha have been found to be more effective than the placebo.What do the results of this study add? This systematic review confirmed the results of previous systematic reviews in a larger sample size. Ginger was more effective than vitamin B, but at the dose of 35-500 mg ginger, vitamin B6 and ginger had identical effect. However, over a longer treatment period (60 days), vitamin B6 was proved to be more effective than ginger.What are the implications of these findings for clinical practice and further research? Matricaria chamomilla, elettaria cardamomum, pomegranate and spearmint syrup, lemon and ginger can be recommended to pregnant women for alleviation of NVP.
