Leadership Empowerment Behaviors and Nurse’s Intention to Leave in Al Wakra Hospital- HMC

2025-09-19T09:50:41+07:00

Nurse turnover is a global challenge that significantly impacts healthcare systems, leading to staffing shortages, increased workload, and compromised patient care. Despite growing literature on LEB, limited research exists on its impact on turnover intentions among nurses in Qatar. This study aims to examine the relationship between LEB and nurses’ intention to leave in Al Wakra Hospital, Qatar. It also explores demographic, structural, and organizational factors contributing to turnover intentions. A cross-sectional study design was employed, surveying registered nurses at Al Wakra Hospital. The study utilized the Leadership Empowering Behavior Questionnaire (LEBQ) and the Turnover Intention Scale (TIS-6) to assess the relationship between leadership empowerment and nurses’ intention to leave. Data were collected through an online survey and analysed using descriptive and inferential statistics, including Pearson correlation and multiple regression analysis. The study found a moderate level of perceived leadership empowerment (mean score 86.9 ± 20.4) and a significant turnover intention (mean score 45.1 ± 13.8). Nurses who perceived higher levels of leadership empowerment reported lower turnover intentions (r = -0.28, p < 0.05). Higher turnover intentions were observed among nurses holding advanced degrees (p = 0.021). No significant differences were found in turnover intentions based on age, gender, or shift type. Leadership empowerment behaviors are inversely related to turnover intentions among nurses in Qatar. Enhancing leadership empowerment strategies, particularly in areas such as information sharing and decision-making autonomy, may help reduce nurse turnover. The findings provide valuable insights for healthcare policymakers and administrators in developing targeted retention strategies.

Impact of Chronic Kidney Disease on Biochemical Profiles and Clinical Outcomes: A Cross-Sectional Comparative Study

Chronic kidney disease (CKD) represents a major global health challenge, marked by a gradual and irreversible decline in renal function. In this cross-sectional case–control investigation, we examined the biochemical and clinical alterations observed in CKD patients compared with age- and sex-matched healthy individuals. The study assessed key biochemical indicators including serum creatinine, blood urea nitrogen (BUN), glomerular filtration rate (GFR), electrolytes, calcium, phosphate, hemoglobin, hematocrit, and albumin. Additionally, common clinical manifestations such as hypertension, edema, fatigue, and dyspnea were documented. Statistical analysis revealed significant increases in creatinine, BUN, phosphate, and potassium among CKD patients (p < 0.05), while GFR, hemoglobin, hematocrit, and albumin levels were markedly decreased. Hypertension (75%) and edema (57.5%) emerged as the most prevalent clinical signs. These findings underscore the necessity of early biochemical screening and clinical monitoring to delay disease progression and minimize complications.

Use of Complementary and Alternative Medicine in Cancer and Its Impact on Survival: A Systematic Review

2026-01-04T06:59:52+07:00

The use of complementary and alternative medicines (CAMs) among cancer patients has increased steadily over the years in response to the search for a more comprehensive method for the relief and care of these patients. The incorporation of traditional Chinese medicines (TCM), herbs, and naturopathic medicines within the field of oncology still has an unclear effect on the survival rate. This systematic review integrates available evidence from empirical studies exploring the interface between the usage of CAM and survival benefits in relation to overall survival (OS), progression-free survival (PFS), or quality of life (QOL) in patients with cancer. In this study, eleven peer-reviewed articles, which include randomized controlled trials, cohorts, and case series, were analyzed according to the PRISMA 2020 guidelines. Data were extracted from the PubMed, Scopus, Web of Science, and Embase database, ranging from 2000-2025. They were assessed for their quality using the RoB 2, which is the Cochrane RoB. The results showed variable findings. Studies like Johnson et al. (2018) and others, such as Ma et al. (2011), indicated a poorer outcome in patients substituting CAM for Western medication, owing largely to drug refusal. Meanwhile, the outcome showed improved OS and PFS for combined CAM strategies, starting from 30% up to 70%, as seen in studies conducted by Li et al. (2019), Xu et al. (2021), and Zhao et al. (2024). The quality of life, as well as decreased toxicity, was likewise documented. CAM, when used adjunctively, may enhance survival and well-being; however, substitution for standard care is associated with reduced survival. Integrative, patient-centered oncology models emphasizing safe, evidence-informed CAM use are recommended.
