Laboratuarda numune reddedilme nedenleri ve red oranlarının azaltılması

Objective: Sample rejection is an important step in the laboratory related with the patient safety. Periodical analysis of rejected samples is necessary to define the causes of rejection and follow-up the requirements for staff training. In this study, we aimed to put forth the efficiency of trainings by analyzing the amount of rejected samples in Yozgat State Hospital. Materials and methods: Taken from laboratory information system (LIS), rejected sample statistics related to 8 month-data before training was compared with 8-month data after training between 07.2015 and 10.2016 are examined. These datas were compared in itself and to each other. All statistical analyses were performed using the SPSS (V15). Results: Before training, the average number of patients for the analysis included months was 34,733 [standard deviation (SD) ± 4031], the number of rejected samples was 397.7 (SD ± 85.3) and the average rejection percentage was 1.13 (min-max: 1–1.29). The average number of patients for the after training months was 39,426 (SD ± 4779), the number of rejected samples was 343.2 (SD ± 57.7) and the average rejection percentage was 0.87 (min-max: 0.62–0.98), Rejected sample rates were significantly lower interms of statistics in the after-training group (p = 0.0001). Conclusion: Staff training takes a very important place preventing these mistakes. As it can be seen in our study, training helps decreasing rejection rates. It is suggested to schedule more trainings in order to decrease the rates to lower degrees.Amaç: Numune reddi, laboratuarda hasta güvenliği ile ilgili önemli bir önlemdir. Reddedilen örneklerin periyodik olarak analizi, personelin eğitimin ihtiyaçlarını belirlenmesi ve personele gerekli eğitimlerin verilerek numune güvenliğinin sağlanmasına hizmet eder. Bu çalışmada, Yozgat Devlet Hastanesinde reddedilen numunelerin analiz ederek eğitimlerin etkinliğini ortaya koymayı amaçladık. Materyal-Metod: Numune reddi ile ilgili bilgiler 07,2015 ve 10,2016 tarihleri arasını kapsayacak şekilde Laboratuvar bilgi sisteminden (LIS) alındı. Eğitimden önceki 8 aylık verilerle ile eğitimden sonraki 8 aylık veriler kendi içlerinde ve birbirleriyle karşılaştırıldı. Tüm istatistiksel analizler SPSS (V15) kullanılarak yapıldı. Sonuçlar: Eğitimden önceki sekiz aylık dönem de ortalama hasta sayısı 34.733 (SD ± 4031), reddedilen numune sayısı 397,7 (SD ± 85,3) ve ortalama reddedilme yüzdesi 1,13 (min-max: 1–1,29) olarak bulunmuştur. Egzersiz sonrası aylardaki ortalama hasta sayısı 39.426 (SD ± 4779), reddedilen numune sayısı 343,2 (SD ± 57,7) ve ortalama reddedilme yüzdesi 0,87 (min-max: 0,62–0,98) bulunmuştur. Reddedilen numune oranları, eğitim sonrası grupta istatistiksel olarak anlamlı ölçüde düşük bulundu (p = 0,0001). Tartışma: Personel eğitimi, laboratuvar hataları önlemede çok önemli bir yer tutmaktadır. Çalışmamızda görülebileceği gibi, eğitim numune reddedilme oranlarının düşürülmesine yardımcı olmaktadır. Numune red oranları düşürmek için daha fazla ve iyi planlanmış eğitimlerin yapılması önerilmektedir

Banking Competition, Financial Liberalization and Economic Growth: Evidence from Turkish Economy during the 1990-2014 Period

After 1950s, economics literature embraced a gradually increasing pattern of studies on economic growth. Empirical studies on the relations among competition in the banking sector, which provides financing to real investments, financial liberalization and economic growth have been increasing since late 1980s. These studies, which have their roots in McKinnon and Shaw approach, investigate whether financial liberalization leads to efficiency rise in the financial sector resulting in economic growth through low cost loans. The objective of this study is to test the relationship among competition in the Turkish Banking Sector, financial liberalization and economic growth over 1990-2014 period using annual time-series data. The findings suggest that over the study period, competition is positively and liberalization is negatively related to economic growth in Turkey.  Keywords: Banking competition, H statistics, liberalization, economic growth, Turkish economy JEL Classifications: G21, L11, O1

Bleeding risk in patients with acute coronary syndrome in a Turkish population results from the Turkish acute coronary syndrome registry (TACSER) study

Objective Bleeding is one of the most important causes of mortality in patients with acute coronary syndrome (ACS). This study therefore aimed to investigate bleeding risk in patients with ACS who were scheduled to receive dual antiplatelet therapy (DAPT) in Turkey. Methods This was a multicentre, observational, cross-sectional cohort study. The study population included 963 patients with ACS from 12 centres in Turkey. We used the Predicting Bleeding Complication in Patients Undergoing Stent Implantation and Subsequent Dual Antiplatelet Therapy (PRECISE-DAPT) score to predict the bleeding risk for all the patients. The patients were divided into high (>= 25) or low (= 25). Compared with the male patients, the female patients had higher PRECISE-DAPT scores (28.2 +/- 15.7 vs 18.4 +/- 13.6,P = 25 was 53%, while among the male patients, the score occurred at a rate of 22%. The female patients had lower haemoglobin (Hb) levels than the male patients (12.1 +/- 1.7 vs 13.8 +/- 1.9,P < .001) and lower creatinine clearance (70.7 +/- 27.5 vs 88.7 +/- 26.3,P < .001). The in-hospital bleeding rates were higher among the patients with high PRECISE-DAPT scores than among those who did not have high scores. Furthermore, the patients with high PRECISE-DAPT scores had a higher in-hospital mortality rate compared with those with low PRECISE-DAPT scores (1% vs 0%,P = .11). Conclusions The mean PRECISE-DAPT score was high among the patients with ACS in this study, indicating that the bleeding tendency was high. This study showed that the PRECISE-DAPT score may help physicians determine the type and duration of DAPT, especially in patients with ACS in Turkey
