The COVID-19 pandemic has imposed challenges to health systems and institutions, which had to quickly create conditions to meet the growing health needs of the population. Thus, this study aimed to assess the impact of COVID-19 on professional nursing practice environments and to identify the variables that affected their quality. Quantitative, observational study, conducted in 16 Portuguese hospitals, with 1575 nurses. Data were collected using a questionnaire and participants responded to two different moments in time: the pre-pandemic period and after the fourth critical period of COVID-19. The pandemic had a positive impact on the Structure and Outcome components, and a negative trend in the Process component. The variables associated with the qualification of the components and their dimensions were predominantly: work context, the exercise of functions in areas of assistance to COVID-19 patients, length of professional experience and length of experience in the service. The investment in professional practice environments impacted the improvement of organizational factors, supporting the development of nurses’ work towards the quality of care. However, it is necessary to invest in nurses’ participation, involvement and professional qualifications, which are aspects strongly dependent on the institutions’ management strategies.

Aim To analyse the impact of COVID‐19 on professional nursing practice environments and patient safety culture. Background The relationship between work environments and patient safety has been internationally recognized. In 2020, the pandemic imposed enormous challenges, yet the impact on these variables remains unknown. Method This is a quantitative observational study, conducted in a Portuguese hospital, with 403 registered nurses. A self‐completion questionnaire was used. Results The impact on the Structure and Outcome components of nursing professional practice environments was positive. Although the Process component remained favourable to quality of care, a negative trend was confirmed in almost all dimensions. The results regarding safety culture showed weaknesses; ‘teamwork within units’ was the only dimension that maintained a positive culture. Conclusion Positive responses regarding patient safety were significantly associated with the quality of the nursing professional practice environment. The need to invest in all dimensions of safety culture emerges to promote positive professional environments. Implications for nursing management Improving professional nursing practice environments can be achieved through managers' investment in the participation and involvement of nurses in the policies and functioning of institutions, as well as promoting an open, fair and participatory safety culture that encourages reporting events and provides adequate support for professionals.

Brazilian popular medicine, in relation to phytotherapy/herbal medicine, is characterized by a great biodiversity and the contribution of different ethnic groups, allied to the transmission of knowledge by successive generations. In this context, the use of complementary medicines in health supplies a large part of the population's needs, and so it should be promoted in a rational way. Thus, a descriptive observational study was carried out on the knowledge of complementary medicines, with an emphasis on phytotherapy, among pharmacy students at a university in Brazil, with the objective of making a diagnosis of knowledge and perception on this topic. Among them, most did not demonstrate mastery of the subject, which is mainly due to the lack of addressing it during graduation, which is also the reason why they do not consider themselves able to work professionally with complementary medicines. However, most consider this practice important, making use of it and showing interest in courses on the subject. These studies corroborate with other Brazilian studies, demonstrating the need for a greater discussion on complementary medicines  and phytotherapy in the academic field to enable the education of qualified professionals to work in this area.

Background The COVID-19 pandemic reinforced the need to invest in nursing practice environments and health institutions were led to implement several changes. In this sense, this study aimed to analyze the impact of the changes that occurred in nursing practice  environments between the first and fourth critical periods of the pandemic. Methods Quantitative, observational study, conducted in a University Hospital, with the participation of 713 registered nurses. Data were collected through a questionnaire with sociodemographic and professional characterization and the Scale for the Environments Evaluation of Professional Nursing Practice, applied at two different points in time: from 1 to 30 June 2020 and from 15 August to 15 September 2021. Data were processed using descriptive and inferential statistics. Results Overall, the pandemic had a positive impact on nursing practice environments. However, the Process component remained favourable to quality of care, while the Structure and Outcome components only moderately favourable. Nurses working in Medicine Department services showed lower scores in several dimensions of the Structure, Process and Outcome components. On the other hand, nurses working in areas caring for patients with COVID-19 showed higher scores in several dimensions of the Structure, Process and Outcome components. Conclusions The pandemic had a positive impact on various dimensions of nursing practice environments, which denotes that regardless of the adversities and moments of crisis that may arise, investment in work environments will have positive repercussions. However, more investment is needed in Medicine Department services, which have historically been characterised by high workloads and structural conditions that make it difficult to promote positive and sustainable workplaces.
