Antimicrobial self-medication is common in most low and middle income countries (LMICs). However there has been no systematic review on non-prescription antimicrobial use in these settings. This review thus intended to establish the burden, risk factors and effects of antimicrobial self-medication in Low and Middle Income Countries. In 2012, we registered a systematic review protocol in PROSPERO (CRD42012002508). We searched PubMed, Medline, Scopus, and Embase databases using the following terms; “self-medication”, “non-prescription”, ‘self-treatment’, “antimicrobial”, “antimalarial”, “antibiotic”, “antibacterial” “2002-2012” and combining them using Boolean operators. We performed independent and duplicate screening and abstraction of study administrative data, prevalence, determinants, type of antimicrobial agent, source, disease conditions, inappropriate use, drug adverse events and clinical outcomes of antibiotic self-medication where possible. We performed a Random Effects Meta-analysis. A total of thirty four (34) studies involving 31,340 participants were included in the review. The overall prevalence of antimicrobial self-medication was 38.8 % (95 % CI: 29.5-48.1). Most studies assessed non-prescription use of antibacterial (17/34: 50 %) and antimalarial (5/34: 14.7 %) agents. The common disease symptoms managed were, respiratory (50 %), fever (47 %) and gastrointestinal (45 %). The major sources of antimicrobials included, pharmacies (65.5 %), leftover drugs (50 %) and drug shops (37.5 %). Twelve (12) studies reported inappropriate drug use; not completing dose (6/12) and sharing of medicines (4/12). The main determinants of antimicrobial self-medication include, level of education, age, gender, past successful use, severity of illness and income. Reported negative outcomes of antimicrobial self-medication included, allergies (2/34: 5.9 %), lack of cure (4/34: 11.8 %) and causing death (2/34: 5.9 %). The commonly reported positive outcome was recovery from illness (4/34: 11.8 %). The prevalence of antimicrobial self-medication is high and varies in different communities as well as by social determinants of health and is frequently associated with inappropriate drug use.

The objective of the review was to synthesize evidence of barriers and facilitators to the integration of mental health services into PHC from existing literature. The structure of the review was guided by the SPIDER framework which involves the following: Sample or population of interest—primary care providers (PCPs); Phenomenon of Interest—integration of mental health services into primary health care (PHC); Design—influenced robustness and analysis of the study; Evaluation—outcomes included subjective outcomes (views and attitudes); and Research type—qualitative, quantitative, and mixed methods studies. Studies that described mental health integration in PHC settings, involved primary care providers, and presented barriers/facilitators of mental health integration into PHC were included in the review. The sources of information included PubMed, PsycINFO, Cochrane Central Register of Controlled trials, the WHO website, and OpenGrey. Assessment of bias and quality was done using two separate tools: the Critical Appraisal Skills Program (CASP) qualitative checklist and the Effective Public Health Practice Project Quality Assessment Tool for Quantitative Studies. Twenty studies met the inclusion criteria out of the 3353 search results. The most frequently reported barriers to integration of mental health services into PHC were (i) attitudes regarding program acceptability, appropriateness, and credibility; (ii) knowledge and skills; (iii) motivation to change; (iv) management and/or leadership; and (v) financial resources. In order to come up with an actionable approach to addressing the barriers, these factors were further analyzed along a behavior change theory. We have shown that the integration of mental health services into PHC has been carried out by various countries. The analysis from this review provides evidence to inform policy on the existing barriers and facilitators to the implementation of the mental health integration policy option. Not all databases may have been exhausted. PROSPERO 2016 (Registration Number: CRD42016052000 ) and published in BMC Systematic Reviews August 2017.

Self-medication with antimicrobial agents is a common form of self-care among patients globally with the prevalence and nature differing from country to country. Here we assessed the prevalence and predictors of antimicrobial self-medication in post-conflict northern Uganda. A cross-sectional study was carried out using structured interviews on 892 adult (≥18 years) participants. Information on drug name, prescriber, source, cost, quantity of drug obtained, and drug use was collected. Households were randomly selected using multistage cluster sampling method. One respondent who reported having an illness within three months in each household was recruited. In each household, information was obtained from only one adult individual. Data was analyzed using STATA at 95% level of significance. The study found that a high proportion (75.7%) of the respondents practiced antimicrobial self-medication. Fever, headache, lack of appetite and body weakness were the disease symptoms most treated through self-medication (30.3%). The commonly self-medicated antimicrobials were coartem (27.3%), amoxicillin (21.7%), metronidazole (12.3%), and cotrimoxazole (11.6%). Drug use among respondents was mainly initiated by self-prescription (46.5%) and drug shop attendants (57.6%). On average, participants obtained 13.9±8.8 (95%CI: 12.6–13.8) tablets/capsules of antimicrobial drugs from drug shops and drugs were used for an average of 3.7±2.8 days (95%CI: 3.3–3.5). Over half (68.2%) of the respondents would recommend self-medication to another sick person. A high proportion (76%) of respondents reported that antimicrobial self-medication had associated risks such as wastage of money (42.1%), drug resistance (33.2%), and masking symptoms of underlying disease (15.5%). Predictors of self-medication with antimicrobial agents included gender, drug knowledge, drug leaflets, advice from friends, previous experience, long waiting time, and distance to the health facility. Despite knowledge of associated risks, use of self-medication with antimicrobial drugs in management of disease symptoms is a common practice in post-conflict northern Uganda.

In Uganda, there are over one million people with HIV/AIDS. When advanced, this disease is characterized by life-threatening opportunistic infections. As the formal health sector struggles to confront this epidemic, new medicines from traditional sources are needed to complement control efforts. This study was conducted to document herbal medicines used in the treatment of HIV/AIDS and related opportunistic infections, and to document the existing knowledge, attitudes and practices related to HIV/AIDS recognition, control and treatment in Sembabule, Kamuli, Kabale and Gulu districts in Uganda. In this study, 25 traditional medicine practitioners (TMPs) were interviewed using structured questionnaires. The TMPs could recognize important signs and symptoms of HIV/AIDS and its associated opportunistic infections. The majority of practitioners treated patients who were already receiving allopathic medicines including antiretroviral drugs (ARVs) prescribed by allopathic practitioners. There were 103 species of medicinal plants identified in this survey. Priority plants identified include Aloe spp., Erythrina abyssinica, Sarcocephalus latifolius, Psorospermum febrifugum, Mangifera indica and Warburgia salutaris. There was low consensus among TMPs on the plants used. Decoctions of multiple plant species were commonly used except in Gulu where mono-preparations were common. Plant parts frequently used were leaves (33%), stem bark (23%) and root bark (18%). About 80% of preparations were administered orally in variable doses over varied time periods. The TMP had insufficient knowledge about packaging and preservation techniques. Numerous medicinal plants for treatment of HIV/AIDS patients were identified in the four districts surveyed and the role of these plants in the management of opportunistic infections warrants further investigation as these plants may have a role in Uganda's public health approach to HIV/AIDS control.

Our aim was to explore peer counselors' work and their role in supporting patients' adherence to antiretroviral treatment (ART) in resource-limited settings in Ethiopia and Uganda. Qualitative semi-structured interviews were conducted with 79 patients, 17 peer counselors, and 22 providers in ART facilities in urban and rural areas of Ethiopia and Uganda. Two main categories with related subcategories emerged from the analysis. The first main category, peer counselors as facilitators of adherence, describes how peer counselors played an important role by acting as role models, raising awareness, and being visible in the community. They were also recognized for being close to the patients while acting as a bridge to the health system. They provided patients with an opportunity to individually talk to someone who was also living with HIV, who had a positive and life-affirming attitude about their situation, and were willing to share personal stories of hope when educating and counseling their patients. The second main category, benefits and challenges of peer counseling, deals with how peer counselors found reward in helping others while at the same time acknowledging their limitations and need of support and remuneration. Their role and function were not clearly defined within the health system and they received negligible financial and organizational support. While peer counseling is acknowledged as an essential vehicle for treatment success in ART support in sub-Saharan Africa, a formal recognition and regulation of their role should be defined. The issue of strategies for disclosure to support adherence, while avoiding or reducing stigma, also requires specific attention. We argue that the development and implementation of support to peer counselors are crucial in existing and future ART programs, but more research is needed to further explore factors that are important to sustain and strengthen the work of peer counselors.
