Background Ethiopia is a multilingual and multinational federation with Addis Ababa serving as both the capital city of Oromia regional state and the seat of the Ethiopian federal government. Nevertheless, only Amharic is considered as the working language of the city and federal offices, including hospitals. As a result, Afaan Oromoo-speaking patients may be facing language barriers in the healthcare settings in Addis Ababa. Language barriers have the capacity to affect patients’ experience of care and treatment outcomes. This study, hence, examined the impacts of language barriers on the healthcare access and quality for the Afaan Oromoo-speaking patients in public hospitals in Addis Ababa. Methods In-depth interviews with patients (N = 27) and key informant interviews with healthcare providers (N = 9) were conducted in six public hospitals found in Addis Ababa. All the interviews were audio-taped and transcribed verbatim. A thematic analysis technique was employed to address the study objectives. Results The study participants indicated the widely existing problem of language discordance between patients and healthcare providers. The impacts of language barriers on the patients include preventable medical errors, low treatment adherence, low health-seeking behavior, additional treatment cost, increased length of hospital stays, weak therapeutic relation, social desirability bias, less confidence, and dissatisfaction with the healthcare. For the healthcare providers, language barriers are affecting their ability to take patient history, perform diagnoses and provide treatment, and have also increased their work burden. The use of ad hoc interpreters sourced from bilingual/multilingual patients, patient attendants, volunteer healthcare providers, and other casual people has been reported to deal with the problem of language barriers. Conclusion A significant number of Afaan Oromoo-speaking patients are facing language barriers in accessing quality healthcare in public hospitals in Addis Ababa, and this constitutes structural violence. As a way out, making Afaan Oromoo an additional working language of the public hospitals in Addis Ababa, the assignment of professional interpreters, and a hiring system that promotes the recruitment of qualified multi-lingual healthcare providers are suggested.

Background Khat (Catha edulis) is a plant commonly found in the horn of Africa whose leaves are chewed for their psycho-stimulant effects. Several studies have demonstrated the association between khat use and mental health problems. Nevertheless, evidence is mixed and inconsistent, warranting further review of available studies. This scoping review is aimed at investigating the content and quality of evidence base on the associations between khat use and mental health disorders and suggesting avenues for further research. Methods We used a scoping review methodology to map the existing evidence using PubMed, SCOPUS, Embase, and CINAHL databases. Primary studies focusing on the association between any pattern of khat use and any form of mental health disorders are included. The review focused on all age groups, any study design, all geographical locations, and any publication year. The terms used for searching eligible studies include khat, mental disorders, and various alternative terminologies. Narrative review is employed to present findings. Results 7,121 articles were found, of which 108 were eligible, conducted across 12 different countries. The majority of the studies was done during the last ten years and the studies mostly employed cross-sectional design. About 10 different categories of mental health disorders have been identified as showing associations with khat use. Despite many contradictory findings between the studies, most of the evidence base suggests that khat use is associated with mental health disorders. Non-specific psychological distress is the most frequently mentioned mental health problem (reported in 26.9% of the studies). Khat use as a predictor variable is mostly assessed using a ‘yes/no’ category, and as a result, dose-dependent effects of khat use on mental health are not given much consideration. Conclusion Although most of the studies associate khat use with mental health disorders, the causal relationships are inconclusive given the cross-sectional design of the studies, and the presence of potential confounders and several forms of biases. Available studies also report contradictory findings. Further studies are recommended using prospective designs, standardized and valid measures of khat use, and focusing on specific types of mental health disorders.
