Despite this inherent hazardous nature of the health care wastes, their treatment and disposal remains neglected and unattended within the urban municipal waste systems in Kenya. The national healthcare waste management plan is yet to be implemented, consequently leaving the management of the health care facilities (HCFs) without a reference on how to manage their wastes. The goal of this study was to provide data that can be used to improve HCWM by analyzing the existing practices currently adopted by the health care facilities. The general objective was to carry out a situation analysis on the management of health care wastes in nongovernment health care facilities. This was a descriptive crosssectional study that assessed health care waste management (HCWM) in 24 nongovernmental (12 mission and 12 private owned) HCFs in the Nairobi provinc...

This was a cross-sectional descriptive study. A total of 300 adult outpatients were randomly selected while they were consulting their general practitioner. The M.I.N.I. Plus interview five was used to diagnose psychiatric disorders and suicide risk. Thus, 56.3 % of the sample (n = 169) presented one or more psychiatric disorders. The most prevalent disorders were Affective (39.0 %), Anxiety (31.3 %), and Somatoform (13.0 %). Regarding specific disorders, the most common were Major Depressive Disorder (26.3 %), Agoraphobia (16.7 %), Pain Disorder (12.5 %), Generalized Anxiety Disorder (9.3 %) and Bipolar Disorder (9 %). We found three cases of Bulimia Nervosa (1 %); 29.7 % had more than one current mental disorder. Suicide risk was present in 12.7 % of participants. No associations were identified between socio-demographic factors and the presence of mental disorder. Suicide risk was higher in women and in patients who came from slum areas. Gastric pain was positively associated with presence of mental disorder. High prevalence of mental disorders and suicide risk calls for integrating mental health services in primary health care; in particular, this study highlights the importance of differentiating between specific types of mental disorders (which require different therapeutic approaches), and of diagnosing comorbidities.
