Trends in Retention and Decay of Basic Surgical Skills: Evidence from Addis Ababa University, Ethiopia: A Prospective Case-Control Cohort Study.

INTRODUCTION: While prior studies have evaluated surgical skills simulation and retention in highly resourced environments, there is paucity of data on the retention of surgical skills taught in simulation laboratory to undergraduate students, and virtually none from low-resource settings. We aimed to evaluate the trends in retention/decay of surgical skills among medical students in Ethiopia and determine whether regular intervention in the form of intermittent skills testing can aid retention. METHODS: Forty-four final year medical students were randomly divided into two cohorts of 22 students each. All 44 were trained in surgical instrument identification, simple interrupted suturing and one-handed knot tying. A previously validated, standardized assessment was performed before training, immediately after training, and then at 6 weeks, 3 months, 6 months and 1 year for cohort 1, and before training, immediately after training, and at 6 months and 1 year for cohort 2. All areas learned were tested for general decay. RESULTS: The baseline mean scores of surgical skills were 3.8/30 for instrument identification, 3.3/15 for one-handed knot tying, and 1.35/15 for suturing. At the end of the training, mean scores improved to 26.6/30, 11.2/15 and 11.1/15 (instrument identification +599% and +772%, knot tying +447% and +417%, suturing +237% and +260%, respectively, for Cohort I and II). At 6 months and 1 year, there was a significant drop in all the three areas tested, especially in knot tying and suturing. There was no statistically significant difference between the two cohorts. CONCLUSIONS: While our surgical skills course is an effective means to teach surgical skills to medical students, there is significant decay in abilities after 6 months. Conducting regular assessments does not appear to have any effect in helping students retain these skills. We recommend such surgical skills training be conducted at appropriate intervals, such as just before internship, to prepare student for active surgical practice.

HIV-infected adolescents have low adherence to antiretroviral therapy: a cross-sectional study in Addis Ababa, Ethiopia.

INTRODUCTION: For antiretroviral therapy (ART) to work effectively, adherence is very crucial. However, most studies done on ART adherence are either on children or on adults. There is limited information on the level of adherence among adolescents. METHODS: Using a cross-sectional study design, we interviewed 273 HIV-infected adolescents receiving ART from three hospitals in Addis Ababa. We used a structured questionnaire to measure adherence levels using patient self-reports. Bivariate and multivariate methods were used for analysis. RESULTS: We interviewed 273 adolescents aged 13 to 19 years, and 144 (52.7%) of the participants were girls. Their mean age was 15.4 years (SD± 1.75). The self-reported adherence rate of the respondents was 79.1% (216/273). On bivariate analysis, variables like WHO clinical stage, being on Cotrimoxazole Prophylactic Therapy (CPT), marital and living status of the parent, whether parent was on ART or not and having special instructions for ART medications were associated with optimum adherence. However of those, only WHO stage IV (adjusted OR, 12.874 95% CI, 2.079-79.706), being on CPT (adjusted OR, 0.339 95% CI, 0.124-0.97) and adolescents with widowed parent (adjusted OR, 0.087 with 95% CI, 0.021-0.359) were found to be significantly associated with optimum ART adherence. CONCLUSION: The level of self-reported ART adherence among HIV-infected adolescents at the three hospitals was below the recommended threshold. Though earlier presentation of adolescents to care should be encouraged, more targeted adherence support should be planned for those who present at an early stage of their illness.

Prevalence and factors associated with diabetes mellitus and impaired fasting glucose level among members of federal police commission residing in Addis Ababa, Ethiopia.

BACKGROUND: The prevalence of diabetes mellitus and factors associated with it, nowadays, are increasing in alarming rates among different occupational groups. Of these occupational groups are Police officers that, often, are exposed to unique life styles and stressful situations which may lead to diabetes mellitus and other cardiovascular diseases. Due to this reason, the present study was conducted to assess the prevalence and factors associated with diabetes mellitus and impaired fasting glucose level among members of federal police commission residing in Addis Ababa, Ethiopia. METHODS: A cross-sectional study design was conducted from April to May 2015. Multistage and systematic random sampling techniques were employed to select the study participants. The study population was federal police commission members living in Addis Ababa and served for at least a year. The data were collected using structured questionnaire, physical examinations and blood samples, based on the WHO stepwise approach. Data were entered in to SPSS version 20.0 and descriptive statistics and logistics regression were used for analysis. RESULTS: Out of the 1003 eligible subjects, 936 (93.3%) police officers have participated in this study. The prevalence of overall impaired glucose homeostasis (IGH) was 120 (13%) of which 47 (5%) were diabetes and 73 (8%) were impaired fasting glucose. Whereas police rank, history of first degree relative who suffered from diabetes, hypertension and waist hip ratio showed a statistical significance with prevalence of diabetes mellitus, age, family history, hypertension, BMI and waist hip ratio were found to be associated with impaired fasting glucose. CONCLUSION: The study identified a high prevalence of IGH among the police officers. A priority should be given on preventive strategies of diabetes mellitus, as that of communicable diseases, by Federal Police Commission Health Service Directorate, Federal Ministry of Health and other concerned partners.
