A best-worst scaling survey of medical students' perspective on implementing shared decision-making in China.

BACKGROUND: The objective of this study was to ascertain the importance rankings of factors affecting the implementation of shared decision-making (SDM) in medical students in China and determine whether these factors were consistent across the respondents' individual characteristics. METHOD: Students studying clinical medicine were recruited from three medical universities in China. A cross-sectional online survey using best-worst object scaling with a balanced incomplete block design was adopted to investigate their preference towards implementing SDM in China. Count analysis, multinomial logit analysis and mixed logit analysis were used to estimate the preference heterogeneity of the SDM factors among respondents. RESULTS: A total of 574 medical students completed the online survey. The three most important factors for implementing SDM were trust and respect, (providing) high-quality medical information and multi-disciplinary collaboration. The mixed logit regression model identified significant heterogeneity in SDM preferences among respondents, and sub-group analysis showed that some heterogeneities varied in respondents by sex, study programs and their experience of visiting doctors. CONCLUSION: The importance rankings provide rich information for implementing SDM and facilitate the reform of education in medical schools in China. However, the heterogeneities in SDM preference need further explorations.

Clinical assessment of preventing febrile nonhemolytic transfusion reaction by leukocyte-depleted blood transfusion.

The objective was designed to assess the clinical efficiency of preventing febrile nonhemolytic transfusion reactions (FNHTR) with transfusion of leukocyte-depleted RBC and platelet concentrates. One hundred patients with cirrhosis of liver, gastric ulcer and cancer were selected to receive RBC concentrates with leukocyte filtration. Another group of 50 patients with liver necrosis, gastric ulcer and cancer were selected to receive non-filtered RBC concentrates. Two hundred and forty patients with acute or chronic leukemia, aplastic anemia, multiple myeloma, thrombocytopenia purpura, diabetes mellitus, cirrhosis of liver, upper gastrointestinal hemorrhage, severe hepatitis, burn and cancer post radioactive or chemical treatment were divided into two group with 120 patients in each one and selected randomly to receive platelet concentrates. The incidence rates of FNHTR in all patients were investigated. Results showed that there was no FNHTR in 100 transfusions with leukocyte-depleted RBC concentrates. Eight out of 50 patients with non-filtrated RBC concentrates showed FNHTR. The incidence of FNHTR was sixteen (16%) in non-filtrated transfusion. Twenty-five and 7 patients manifested FNHTR respectively in non-filtrated or filtrated platelets transfusions. The incidence of FNHTR was 20.83% and 5.83% respectively in non-filtrated or filtrated platelet transfusion. It is concluded that leukocyte-depleted RBC and platelet concentrates reduces FNH TR in blood transfusion.
