Clinical chemistry laboratory test overuse in a cardiology clinic: a single-center study.

Diagnostic laboratory tests are frequently overused in healthcare entities, leading to an increased strain on laboratory resources, additional workload, and wastage of resources. Continuous monitoring of test ordering behavior is crucial to evaluate clinical necessity. This cross-sectional study aimed to estimate the necessity of ordering clinical chemistry tests in the cardiology clinic of a tertiary center in Saudi Arabia. We retrieved medical records of patients diagnosed with cardiovascular problems admitted at the cardiology clinic in 2020. The frequency and percentages of the ordered tests were calculated upon admission and follow-up, and the difference between necessary and unnecessary tests was compared for each category. Test ordering assessment included cardiac, renal, and liver functions, blood gases, thyroid and diabetic profile, iron indices, hormones, water and electrolytes, and inflammatory markers. The results showed a large number of clinical chemistry tests ordered without clinical necessity. While the number of necessary tests was significantly higher than that of unnecessary tests, 21% of the tests ordered between June-December 2021 at the center were unnecessary. Further studies are necessary to identify driving factors and develop strategies to reduce the overutilization of diagnostic laboratory tests in clinical practice. Eliminating this phenomenon will reduce the risk of unnecessary medical interventions and associated costs, improve patient outcomes, and reduce the overall burden on the healthcare system.

The prevalence and associated factors of shisha use among smokers attending three primary healthcare centers in Qatar, 2020.

INTRODUCTION: Smoking is one of the most serious health issues. One form of tobacco use, shisha, is prevalent in the Eastern Mediterranean Region. There is a misconception among smokers that waterpipe use poses no harm to human health. In Qatar, the Global Adult Tobacco Survey in 2013 has shown that 3.4% of adults in the country were current waterpipe users. Nevertheless, there remains a scarcity of data on the knowledge and practice of shisha smokers in Qatar. METHODS: This was a cross-sectional study across three primary healthcare (PHC) centers in Qatar between September and December 2020. A convenient sampling technique was employed to enroll participants. Upon consent, an interview was conducted to collect data from adult smokers (aged ≥18 years). Descriptive and analytic statistics were used when appropriate. RESULTS: A total of 281 individuals participated in this study. Nearly half (48.8%) were current shisha users and almost three-quarters (72.9%) had inadequate knowledge in this regard. In addition, only one-fifth (19.5%) of participants attended smoking cessation clinics at the primary healthcare centers and a quarter (25%) of the respondents managed to quit smoking before relapsing. A significant association was found between the shisha knowledge of participants and their nationality (Qatari), employment status (unemployed), smoking status (current smoker), and duration of smoking. CONCLUSIONS: The study results convey a high prevalence of shisha use (47.8%), inadequate shisha knowledge (72.9%), and lack of awareness about available smoking cessation services (46.6%) among the participants. Further research is recommended to generate evidence on the determinants of shisha use and knowledge among the attendees of primary healthcare centers in Qatar.

Learning style among family medicine residents, Qatar.

Different learning style among family medicine residents is important to adjust the educational program that meet their needs and make the educational process fruitful to improve their academic performance. This study is aiming to assess learning styles among family medicine residents in Qatar. This cross-sectional descriptive study was conducted at the West Bay family medicine training center, Doha, Qatar, where all family medicine residents were invited to participate using self-administered validated questionnaire based on David Kolb model of experiential learning that has been extensively used in medical education research. Demographic data were assessed and analyzed as the predictor variables. Data were collected from 38 residents with response rate 76% revealing that the predominant pattern in postgraduate year one (PGY1) is activist in 65% and theorist in 55% while PGY2 tends to be reflector in 45% and theorist in 35% and in PGY3-4 changed to be 70-75% activist and 40-55% (reflector and pragmatic). General learning style pattern among all residents tend to be in the following order: activist 60.5%, then reflector 44.7%, followed by pragmatism 34.2% and finally theorist 36.8%. Learning style assessment is important and can be used to determine which teaching modalities will be best accepted and most effective for family medicine residents which should be considered while planning, designing, and implementing their educational program.

Correlation between ST segment shift and cardiac diastolic function in patients with acute myocardial infarction.

BACKGROUND: Diastolic dysfunction is the early sign of myocardial ischemia that usually occurs earlier than ECG changes. AIM OF THE STUDY: To determine the existence of a correlation between ST segment shift and diastolic dysfunction among patients with AMI. METHODS: Fourty six patients with significant ST segment elevation or depression and having symptoms of acute myocardial infarction for <12 h were enrolled in this study. Patients were examined for serial ECG, cardiac enzymes, and echocardiography. RESULTS: There was no significant correlation between ST segment elevation or depression and majority of the diastolic indices. Few diastolic parameters; such as, E/A ratio of the mitral valve and deceleration time of the tricuspid valve showed a direct correlation with the ECG changes. Whereas, the Tei Index of the LV function showed a borderline correlation to the ST segment elevation at discharge. CONCLUSION: Overall, there was no correlation between either ST segment elevation or depression and the LV or RV diastolic function in patients with acute coronary syndrome (ACS). Improvement of the ST segment total score was associated with improvement of the diastolic function grades at discharge. Moreover, this association has shown an evidence of dose response relationship, the more improvement in total score at discharge the more improvement in diastolic function grade level.
