Strategies for maintaining and strengthening the health care workers during epidemics: a scoping review.

INTRODUCTION: During epidemics such as COVID-19, healthcare workers (HCWs) face several challenges, leading to a shortage and weakening of human resources. To address this issue, employing effective strategies is essential in maintaining and strengthening human resources during outbreaks. This study aimed to gather and classify strategies that could retain and strengthen human health resources during epidemics. METHODS: In this scoping review, all studies published about strategies for maintaining and strengthening HCWs in epidemics were collected from 4 international databases, including PubMed, Embase, Scopus, and Web of Science. The English language articles published after 2000 up until June 2022 recommended specific strategies regarding the research question. Then, they were analyzed and classified according to thematic analysis based on Braun and Clarke 6 phases protocols. RESULTS: In total, 9405 records were screened, of which 59 articles were included, and their full texts were reviewed. Fifty factors were identified and classified into five themes: Instruction, Protection, Supporting, Caring, and Communication. Most of the suggestions were conducted in high-income countries and related to the Supporting theme. DISCUSSION: The majority of strategies discussed in the literature addressed only one or two aspects of human resources. This study provides a holistic perspective on these issues by providing a thematic map of different strategies for strengthening and maintaining HCWs during epidemics. Considering the multidimensionality of human nature, it is suggested that policymakers and managers of health systems provide facilities that simultaneously address a wide range of needs.

The Effect of L-Arginine Oral Supplementation on the Improvement of Cardiovascular Function and Pulmonary Artery Pressure in Patients with Major and Intermedia ß-Thalassemia.

Background: Thalassemia is the most common inherited anemia in worldwide. Heart failure is the most common cause of mortality and morbidity in patients with major and intermedia ß-thalassemia. This study aimed to evaluate the effect of oral administration of L-arginine on the improvement of systolic Pulmonary Artery Pressure (PAP) and cardiac function in patients with major and intermedia ß-thalassemia. Methods: This randomized clinical trial was done on 88 patients with ß-thalassemia admitted to Ali Asghar Hospital, Tehran, Iran between 2020 and 2021. Echocardiography was performed for all the patients before the intervention. Afterwards, the patients were randomly divided into two groups of placebo and L-arginine. The patients underwent echocardiography after eight weeks and were compared with respect to the results. Results: The mean blood transfusion interval was 20.21 d in the placebo group and 17.14 d in the L-arginine group (P=0.082). The results revealed no significant difference between the two groups regarding the mean levels of Hemoglobin (Hb) and ferritin, frequency of splenectomy. However, the mean PAP significantly decreased from 32.88 to 26.02 in the L-arginine group (P=0.009), but did not change in the placebo group. Nonetheless, no significant change was observed in the mean Ejection Fraction (EF) before and after L-arginine administration. Conclusion: L-arginine administration prevented the increase of PAP and was effective in preventing cardiovascular disorders including increased systolic PAP in patients with major and intermedia B-thalassemia. However, the results have to be confirmed in further studies with larger sample sizes.
