DESIGN: Qualitative study utilising semi-structured in-depth interviews. The interviews were conducted in English language.
SETTING: Different healthcare facilities across the UAE. These facilities were accessed for data collection over a period of 3 months from January 2023 to March 2023.
PARTICIPANTS: 14 purposively selected healthcare practitioners.
INTERVENTION: No specific intervention was implemented; this study primarily aimed at gaining insights through interviews.
PRIMARY AND SECONDARY OUTCOMES: To understand the implications of language barriers on service quality, patient safety, and healthcare providers' well-being.
RESULTS: Three main themes emerged from our analysis of participants' narratives: Feeling left alone, Trying to come closer to their patients and Feeling guilty, scared and dissatisfied.
CONCLUSIONS: Based on the perspectives and experiences of participating healthcare professionals, language barriers have notably influenced the delivery of healthcare services, patient safety and the well-being of both patients and practitioners in the UAE. There is a pressing need, as highlighted by these professionals, for the inclusion of professional interpreters and the provision of training to healthcare providers to enhance effective collaboration with these interpreters.
METHODS: In this study, a systematic review and a meta-analysis study were conducted on CT phantom for resolution study especially based on the low contrast detectability (LCD). Furthermore, the association between the CT parameter such as tube voltage and the type of reconstruction algorithm, the amount of phantom scanning affecting the image quality and the exposure dose were also investigated in this study. We utilize PubMed, ScienceDirect, Google Scholar and Scopus databases to search related published articles from the year 2011 until 2020. The notable keywords comprise "computed tomography", "CT phantom", and "low contrast detectability". Of 52 articles, 20 articles are within the inclusion criteria in this systematic review.
RESULTS: The dichotomous outcomes were chosen to represent the results in terms of risk ratio as per meta-analysis study. Notably, the noise in iterative reconstruction (IR) reduced by 24%, 33% and 36% with the use of smooth, medium and sharp filters, respectively. Furthermore, adaptive iterative dose reduction (AIDR 3D) improved image quality and the visibility of smaller less dense objects compared to filtered back-projection. Most of the researchers used 120 kVp tube voltage to scan phantom for quality assurance study.
CONCLUSION: Hence, optimizing primary factors such as tube potential reduces the dose exposure significantly, and the optimized IR technique could substantially reduce the radiation dose while maintaining the image quality.
METHODS: This is a single-center, cross-sectional study using in-patient data maintained by the Case-Mix Unit of a teaching hospital in Malaysia from 2016 to 2017. The study included all patients with International Classification of Disease (ICD) code 164 (stroke, not specified as hemorrhage or infarct). The significance of association was determined using nonparametric tests in the form of the Mann-Whitney U test and the Kruskal-Wallis test.
RESULTS: A total of 162 stroke patients from 2016 to 2017 from Case-Mix database were included in the study. The age ranged from 31 to 97 years old. The minimum and maximum LOS for patients with stroke ranged from 1 to 17 days. The severity of illness was found to be significantly associated with longer LOS (p < 0.001); however, age, sex, and presence of co-morbidities did not show any significant association.
CONCLUSION: Despite its limitations, this study is an essential first step to examine the characteristics of patients with stroke and to determine the factors associated with LOS.
MATERIALS AND METHODS: We traced CT scans of 106 knees with no patellofemoral pathology from 59 subjects from the database system and converted all 2-D images into 3-D models to determine the values for each parameter. We compared the intra- and interobserver reliability of each method using intraclass correlation (ICC) and Bland-Altman method.
RESULTS: The values of TT-TG measured by 2-D and 3-D methods were 16.1 ± 4.6 mm and 16.2 ± 4.2 mm, respectively. The ICC values of both methods were comparable (95% limits of agreement between the same observer: - 3.3 to 3.8 mm versus - 2.4 to 2.7 mm and different observers: - 4.3 to 4.9 mm versus - 3.9 to 2.7 mm), with 3-D method results in narrower limits of agreement.
CONCLUSION: TT-TG measurement is reliable using the 2-D method without using advanced radiographic software. The 3-D method of measuring TT-TG provides measurement with narrower variation when compared with the 2-D method. However, both TT-TG distances' measurement methods in the current study were comparable as the variations are not significant.
METHODS: Retrospective analysis of medical records of patients in the COVID-19 wards of three tertiary care hospitals to assess antibiotic use during the sixth COVID-19 wave.
RESULTS: A total of 284 patients were included, most were male (66.9%), aged 30-50 years (50.7%) with diabetes mellitus the most common comorbidity. The most common symptoms at presentation were cough (47.9%) and arthralgia-myalgia (41.5%). Around 3% were asymptomatic, 34.9% had mild, 30.3% moderate, and 23.6% had severe disease, with 8.1% critical. Chest X-ray abnormalities were seen in 43.3% of patients and 37% had elevated white cell counts, with 35.2% having elevated C-reactive protein levels. Around 91% COVID-19 patients were prescribed antibiotics during their hospital stay, with only a few with proven bacterial co-infections or secondary bacterial infections. Most antibiotics were from the 'Watch' category (90.8%) followed by the 'Reserve' category (4.8%), similar to previous COVID-19 waves.
CONCLUSION: There continued to be excessive antibiotics use among hospitalized COVID-19 patients in Pakistan. Urgent measures are needed to address inappropriate prescribing including greater prescribing of Access antibiotics where pertinent.
