Background Drug related problems interfere with the desired treatment outcomes of type 2 Diabetes mellitus. This study was conducted to determine prevalence of drug related problems and associated factors among patients with type 2 Diabetes Mellitus in public health institutions of Kemisse town, northeast Ethiopia from May 01 to 30, 2019. Methods Institution based retrospective cross sectional study was conducted among type 2 Diabetes Mellitus patents on follow up at public health institutions of Kemisse town, northeast Ethiopia. Result From the total of 156 patients included in the study, 126 (80.8%) patients have at least one drug related problem with a total of 149 drug related problems. The most prevalent drug related problems were need for additional drug therapy 60 (40.3%) followed by non-compliance 51 (34.2%) and unnecessary drug therapy 12 (8%). Identified causes of need for additional drug therapy were the need for prophylactic drug therapy (statins and antiplatelet), 83.3%; presence of untreated medical condition (Hypertension, diabetic nephropathy and diabetic foot ulcer), 11.7%; and the need for combination therapy for better efficacy, 5%. This study revealed that age ≥45 years (AOR = 5.59, 95% CI = 1.38–20.64, P = 0.016), presence of comorbid condition (AOR = 3.22, 95% CI = 1.75–13.47, P = 0.014 and emergency visit in the last one year (AOR = 5.08, 95% CI = 1.14–18.71, P = 0.033) were significantly associated with the occurrence of drug related problems. Conclusion A total of 149 drug related problems were identified in 80.8% of type 2 diabetes mellitus patients. The three most prevalent drug related problems were need for additional drug therapy 60 (40.3%) followed by non-compliance 51 (34.2%) and unnecessary drug therapy 12 (8%). Additionally, age ≥45 years (AOR = 5.59, P = 0.016), presence of comorbidity (AOR = 3.22, P = 0.014) and emergency visit in the last one year (AOR = 5.08, P = 0.033) were significantly associated with the occurrence of drug related problem.

This study aims to evaluate yield performance of faba bean (Vicia faba L.) varieties with data from field experiment that was conducted at Alarigeta testing site of Bonga Agricultural Research Center in the 2012 and 2013 cropping seasons using six improved faba bean varieties with the local check. The improved varieties included in the study were Cs-20-DK, Degaga, Tumsa, Hachalu, Dosha, and Walki. These varieties were assigned to the Randomized Complete Block Design with three replications. In this experiment, yield and yield related traits of the improved varieties were measured and evaluated against the performance of the local check. The combined analysis of the over year experiment showed significant (P<0.05) differences among varieties for most of the parameters studied such as grain yield, number of pods per plant, hundred seed weight, days to flowering and maturity. The varieties Tumsa and Hachalu were found to be high yielder with the value of 6.31 and 5.86 tons ha -1 , respectively. Selected farmers around the experimental site made the assessment on the performance of the evaluated varieties at flowering and physiological maturity stages. They evaluated and ranked these varieties using their own criteria. According to their perception on the performance of the varieties they also ranked Tumsa and Dosha at the first and second level, respectively. The results obtained from the statistically analysis combining the farmers' preference revealed that Tumsa, and Dosha were the best performing varieties in all measured traits as compared to others. Therefore, varieties Tumsa and Dosha could be used for popularization and wider production by the farmers in the study area and in the farming communities of similar agro-ecologies. Use of the appropriate technology packages and optimum crop management practices along with these varieties is also recommended in order to attain maximum productivity.
