Purpose: This study aimed to translate and culturally adapt the self-report and parent-proxy Health-Related Quality of Life Measure for Children with Epilepsy (CHEQOL-25) into Vietnamese and to evaluate their reliability.

Methods: Both English versions of the self-report and parent-proxy CHEQOL-25 were translated and culturally adapted into Vietnamese by using the Principles of Good Practice for the Translation and Cultural Adaptation Process. The Vietnamese versions were scored by 77 epileptic patients, who aged 8–15 years, and their parents/caregivers at neurology outpatient clinic of Children Hospital No. 2 – Ho Chi Minh City. Reliability of the questionnaires was determined by using Cronbach’s coefficient α and intra-class correlation coefficient (ICC).

Results: Both Vietnamese versions of the self-report and parent-proxy CHEQOL-25 were shown to be consistent with the English ones, easy to understand for Vietnamese children and parents. Thus, no further modification was required. Cronbach’s α coefficient for each subscale of the Vietnamese version of the self-report and parent-proxy CHEQOL-25 was 0.65 to 0.86 and 0.83 to 0.86, respectively. The ICC for each subscale of the self-report and parent-proxy CHEQOL-25 was in the range of 0.61 to 0.86 and 0.77 to 0.98, respectively.

Conclusion: The Vietnamese version of the self-report and parent-proxy CHEQOL-25 were the first questionnaires about quality of life of epileptic children in Vietnam. This Vietnamese version was shown to be reliable to assess the quality of life of children with epilepsy aged 8–15 years.

Since 2011, English for Specific Purposes (ESP) curriculum in Faculty of Pharmacy, University of Medicine and Pharmacy at Ho Chi Minh City (Vietnam) has been changed in accordance with pharmaceutical specialization orientation and did apply the active learning-learner centered teaching methods. Our study used three self-administered questionnaires to collect the feedbacks from sophomores, final-year and pharmacist graduating in 2016 in evaluating ESP course effectiveness. Data analyzed with STATA 13 indicated that English lecturers made efforts to organize the active learning activities in ESP class but their target has neither been effective nor met the required students’ needs in academic purposes as well as their occupational purposes. In addition, students’ passivity and lack of apparent motivation made it more difficult to apply the active learning method. Generally, final-year pharmacy students and newly graduated pharmacists, besides their moderate English competence, had a low frequency in using English. It is also found that there exists the relationship between final-year pharmacy students’ frequency of using English, their English competence and pharmaceutical specialization as well as that between English use frequency and occupation.

Background: Enteral nutrition therapy via nasogastric tube can be administered through continuous or intermittent feeding methods for critically ill patients. However, there has not been existing consensus on the superiority of either method for mechanically ventilated patients due to insufficient evidence comparing the effectiveness of the two methods. The present study aimed to compare the impact of continuous versus intermittent feeding methods on gastrointestinal intolerance in mechanically ventilated patients.

Methods: 41 mechanically ventilated patients in the intensive care unit, University Medical Center, Ho Chi Minh City, Vietnam from 3/2017 to 5/2017 were enrolled in a randomized controlled trial. They were randomly and equally assigned to the two study groups and monitored for 4 consecutive days on incidence of gastrointestinal intolerance including high gastric residual volume, abdominal distention, diarrhea, and tube occlusion.

Results: There was statistically significant difference when comparing the gastric residual volumes between two groups with a median at 0.93ml (0.09-1.93) versus 11.61ml (7.61-17.28) (p < 0.001). The mean number of abdominal distention episodes in the continuous group was significantly lower than in the intermittent group (2.8 ± 2.66 versus 8.29 ± 5.1 episodes, respectively, p < 0.001). The diarrhea scores were not significantly different (p < 0.05) and there were no cases of occlusion recorded in the two groups.

Conclusions: Continuous feeding method offered less gastrointestinal intolerance than intermittent feeding method by reducing gastric residual volumes and limiting abdominal distention. The feeding method did not increase the risk of tube obstruction if it was flushed regularly.

  • Pages 6-11

Background: Assessments of professional behaviors such as professionalism Mini clinical examination (PMEX) and OSCE (POSCE) are playing an important role in driving the practice professionalism in medical training. Simulation-based assessment or POSCE has been used to evaluate several professional attributes. However, few evidence of content validity proving that whether POSCE is really measuring specific professional attributes have been reported in medical education literature.

Methods:  The four-step process of developing FM POSCE was analyzed to highlight the validity evidence according framework of Downing (2003). Group of 5 independent FM experts from Vietnam, Boston University, US and Liege, Belgium evaluated the blueprints, scenarios and item lists on a scale (1-totally disagree to 5-totally agree) regarding to what extent test blueprint, cases and item lists were relevant to the content domains and cultural context. The results of their evaluation were considered as an evidence of content validity. The mean and standard deviation of the scores given by them were calculated using SPSS, 20.0.

Results: Important evidence of content validity were found in the process of developing POSCE. Content experts’ evaluation showed that all professional attributes represented medical professionalism. However, the adequacy of professional attributes to evaluate the broad construct of professionalism was controversial (M=3.75, SD=0.95). Cases are relevant to assess these professional attributes and culture. Only the cases of “Respecting the patient” and “Making altruistic decision” contained some inappropriate marking items (M=3.75, SD=0.95; M=3.00, SD=0.92).  

Discussion and conclusion: FM POSCE developed in Vietnamese context can assess six specific professional attributes. This study suggested a process of developing POSCE that has several features such as using both sources of expertise and medical literature to build up the content of POSCE to improve the content validity.

Pursuing a targeted dream specialty and a research career: Opinions and observations from a fifth-year medical student’s perspective

Letter to Editor
  • Gehad Mohamed Tawfik,
  • Pages 1-4

With our fast-pacing life, numerous learning and scientific sources and information are available and required for medical students to boost their skills since their early life to accommodate with the great knowledge they take. Medical students should re-elaborate what they studied and exploit knowledge clinically. A good doctor is a good observer, so eyes should be kept on while mentor managing patients in order to add more to our medical notions. A seed to become a great future doctor starts by searching for a specialty that fits your personality, to practice it as a volunteer, to gain its skills earlier. So when you graduate, you have more time to gain other learning experience. As long as you practice it, the more chance to become one of its experts. Managing your patient as a relative, not as a bag of money, is very important to be applied. Inability to diagnose a patient is not a shame, so never let a patient go home without referring him to another doctor who has more experience than you. Having a background in other medical specialties will help you recognize common signs of other related medical conditions that could lead you to refer him to right specialty doctor. Joining a research lab will keep you updated with new inventions, drugs, algorithms, and guidelines, which will help you become more acknowledged with medical problems that you were unaware of. Time management is the key to success as a researcher without affecting your daily life activities and study requirements.

  • Pages 5-11

Background: The Diabetes Distress Scale (DDS) is a valid instrument to measure diabetes distress included in American Diabetes Association and Canadian Diabetes Association guidelines but not available in Vietnamese. This study translated and culturally adapted the DDS to assess diabetes distress of Vietnamese type 2 diabetics and evaluated its internal consistency, face and content validity.

Methods: The translation process followed standard guidelines for adaptation of an instrument: forward translation, back translation, synthesis, evaluation by an expert panel and pretest. The expert panel included three English specialists as linguistic experts and six content experts in multidisciplinary areas relevant to the study. The pretest was conducted on a sample of 31 type 2 diabetics in the Endocrinology outpatient clinic at Trung Vuong hospital. Content validity was determined based on experts’ concurrence using content validity index for items (I-CVI). Face validity is assessed by participants in pretest. Internal consistency was measured using Cronbach’s alpha.

Results: Final version was equivalent with the original English version and easy to understand. I-CVI of 17 items were 1.00 in linguistic experts and greater than 0.83 in content experts. All 31 participants involved in the pretest commented that the items were very clear and acceptable regarding their socioeconomic background. Cronbach’s alpha coefficient was 0.76 – 0.93 for each subscale and 0.94 for the overall.

Conclusion: Vietnamese version of the DDS was reliable, face and content-valid to assess diabetes distress in type 2 diabetics among Vietnamese.
