Context and objectiveThe negative consequences of inadequate nursing handovers on patient safety are widely acknowledged, both within the literature as in practice. Evidence regarding strategies to improve nursing handover is, however, lacking. This study investigates the effect of a tailored, blended curriculum on nurses’ perception of handover quality.MethodsWe used a pre-test/post-test design within four units of a Belgian general hospital. Our educational intervention consisted of an e-learning module on professional communication and a face-to-face session on the use of a structured method for handovers. All nurses completed this blended curriculum (n=87). We used the Handover Evaluation Scale (HES) to evaluate nurses’ perception of handover quality before and after the intervention. The HES was answered by 87.4% of the nurses (n=76 of 87) before and 50.6% (n=44 of 87) after the intervention. Confirmatory factor analysis was used to assess the validity of the HES.ResultsThe original factor structure did not fit with our data. We identified a new HES structure with acceptable or good fit indices. The overall internal consistency of our HES structure was considered adequate. Perception of nurses on Relevance of information showed a significant improvement (M=53.19±4.33 vs M=61.03±6.01; p=0.04). Nurses also felt that the timely provision of patient information improved significantly (M=4.50±0.34 vs M=5.16±0.40; p=0.01).ConclusionThe applied intervention resulted in an improved awareness on the importance of Relevance of information during handovers. After our intervention, the nurses’ perception of the HES item ‘Patient information is provided in a timely manner’ also improved significantly. We are aware that the educational intervention is only the first step to achieve the long-term implementation of a culture of professional communication based on mutual support.

COVID-19 is currently a major health problem worldwide. Indonesia is one of the countries affected and is in the 21st position with the most positive cases of Covid in the world. Children who are exposed to the Covid-19 virus usually only cause mild symptoms or even cause no symptoms. This makes children a source of spreading the virus without realizing it. Therefore, education on how to prevent the transmission of Covid-19 (Clean and Healthy Living Behavior) is important to prevent children from being exposed to the Covid-19 virus and becoming a source of infection without realizing it. To determine the effect of comic education and leaflets on increasing the knowledge of parents of elementary school students about PHBS for preventing the transmission of the Covid-19 virus. This study used a quasy experimental design with a desaign pre-post test group design involving 68 parents of grade V students who were selected by cluster random sampling. Knowledge data collection is carried out online. There were differences in respondents' knowledge of the effect of comics education media use (p = 0,) and leaflets (p = 0,). There is an effect of nutrition education through comics and leaflets on knowledge about Clean and Healthy Living Behaviors in parents of elementary school students as an effort to prevent the transmission of the Covid-19 virus. ABSTRAK COVID-19 saat ini menjadi masalah kesehatan paling utama di seluruh dunia. Indonesia menjadi salah satu negara yang terdampak dan menduduki posisi ke-21 dengan kasus positif Covid terbanyak di dunia. Anak yang terpapar virus Covid-19 biasanya hanya menimbulkan gejala ringan atau bahkan tidak menimbulkan gejala. Hal ini membuat anak menjadi sumber penyebaran virus tanpa disadari. Oleh sebab itu, edukasi mengenai cara pencegahan penularan Covid-19 (Perilaku Hidup Bersih dan Sehat) penting dilakukan untuk mencegah anak terpapar virus Covid-19 dan menjadi sumber penularan tanpa disadari. Mengetahui efektivitas edukasi komik dan leaflet terhadap peningkatan pengetahuan orangtua siswa sekolah dasar mengenai PHBS untuk pencegahan penularan virus Covid-19. Penelitian ini menggunakan desain quasy experimental dengan rancangan pre-post test group desaign dengan melibatkan 68 orangtua siswa kelas V yang dipilih dengan cluster random sampling. Pengambilan data pengetahuan dilakukan secara daring. Ada perbedaan pengetahuan responden terhadap efektivitas penggunaan media edukasi komik (p=0,) dan leaflet (p=0,). Media komik dan leaflet dapat meningkatkan pengetahuan mengenai Perilaku Hidup Bersih dan Sehat pada orangtua siswa sekolah dasar sebagai upaya pencegahan penularan virus Covid-19.

Background: Communication in the intensive care setting (ICS) is critical for both the patient and the medical staff to provide efficient care and thus alleviate possible patient adverse effects. Persons with complex communication needs are particularly vulnerable in ICSs and therefore require additional communication support.Aim: This study focused on the perspectives of nurses about communication with patients with communication needs in ICSs using paper-based communication boards, namely the translated Vidatak EZ Board, before and after a training session.Setting: A 1650-bed public hospital with a 26-bed ICS in a semi-urban, low socio-economic area in South Africa served as the research setting.Methods: A quasi-experimental pre-test post-test group design with withdrawal and a control group was used. Data were gathered using a custom-designed questionnaire completed by ICS nurse participants recruited from a public hospital.Results: Responses of some nurses did not change in post-test 1, but their responses did change in post-test 2. Some of the nurses’ perspectives changed, as expected from the pre-test to post-test 1. Nurses recommended specific adaptations to the communication board.Conclusions: Most nurses agreed that communication is crucial in ICSs and that a communication board can be implemented; however, limited success was observed implementing the board following a short training. The inter-professional collaboration between nurses and speech-language therapists to provide optimal health care to patients in ICS is emphasised.
