Comparing the accuracy of brief versus long depression screening instruments which have been validated in low and middle income countries: a systematic review

BackgroundGiven the high prevalence of depression in primary health care (PHC), the use of screening instruments has been recommended. Both brief and long depression screening instruments have been validated in low and middle income countries (LMIC), including within HIV care settings. However, it remains unknown whether the brief instruments validated in LMIC are as accurate as the long ones.MethodsWe conducted a search of PUBMED, the COCHRANE library, AIDSLINE, and PSYCH-Info from their inception up to July 2011, for studies that validated depression screening instruments in LMIC. Data were extracted into tables and analyzed using RevMan 5.0 and STATA 11.2 for the presence of heterogeneity.ResultsNineteen studies met our inclusion criteria. The reported prevalence of depression in LMIC ranged from 11.1 to 53%. The area under curve (AUC) scores of the validated instruments ranged from 0.69-0.99. Brief as well as long screening instruments showed acceptable accuracy (AUC≥0.7). Five of the 19 instruments were validated within HIV settings. There was statistically significant heterogeneity between the studies, and hence a meta-analysis could not be conducted to completion. Heterogeneity chi-squared = 189.23 (d.f. = 18) p<.001.ConclusionBrief depression screening instruments in both general and HIV-PHC are as accurate as the long ones. Brief scales may have an edge over the longer instruments since they can be administered in a much shorter time. However, because the ultra brief scales do not include the whole spectrum of depression symptoms including suicide, their use should be followed by a detailed diagnostic interview.

Household antimicrobial self-medication: a systematic review and meta-analysis of the burden, risk factors and outcomes in developing countries

BackgroundAntimicrobial 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.MethodsIn 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.ResultsA 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 %).ConclusionThe 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.

Sensitivity and specificity of clinician administered screening instruments in detecting depression among HIV-positive individuals in Uganda

Depressive disorders are highly prevalent in Africa where diseases such as HIV/AIDS are common. The aim of this study was to assess the validity of commonly used depression screening instruments in a setting characterized by low literacy, where patients may not be able to self-administer depression scales. We explored the validity of the Patient Health Questionaire-9 (PHQ-9), Centre for Epidemiological Surveys for Depression (CES-D), and the Kessler-10 (K-10), using the Mini International Neuropsychiatric Instrument (MINI) as a gold standard in 368 persons living with HIV/AIDS (PLWHA) in Uganda. The shorter versions of the K-10 and PHQ-9 were extracted to assess their performance in comparison to the longer versions. We used STATA 11.2 to analyze the data. The prevalence of a MINI defined depression in this patient sample was 17.4%. The three instruments all performed well, with areas under the curve (AUC) ranging from 0.82 to 0.96. The PHQ-9 showed the best performance characteristics with an AUC of 0.96, a sensitivity of 91.6%, and specificity 81.2%. The extracted versions performed more modestly. All three instruments showed good properties as screening tools; the PHQ-9 has particularly high sensitivity and specificity, and so can be considered useful for screening HIV-positive patients for depression.

The Association between Aids Related Stigma and Major Depressive Disorder among HIV-Positive Individuals in Uganda

Background Major depressive disorder in people living with HIV/AIDS (PLWHA) is common and may be associated with a number of factors, including AIDS-related stigma, decreased CD4 levels, increased opportunistic infections and sociodemographic variables. The extent to which AIDS-related stigma is associated with major depressive disorder among PLWHA has not been well studied in sub-Saharan Africa. The objective of this study was to examine the associations between major depressive disorder, AIDS-related stigma, immune status, and sociodemographic variables with the aim of making recommendations that can guide clinicians. Methods We assessed 368 PLWHA for major depressive disorder, as well as for potentially associated factors, including AIDS-related stigma, CD4 levels, presence of opportunistic infections, and sociodemographic variables. Results The prevalence of major depressive disorder was 17.4%, while 7.9% of the participants had AIDS related stigma. At multivariable analysis, major depressive disorder was significantly associated with AIDS-related stigma [OR = 1.65, CI (1.20–2.26)], a CD4 count of ≥200 [OR 0.52 CI (0.27–0.99)], and being of younger age [0.95, CI (0.92–0.98). Conclusions Due to the high burden of major depressive disorder, and its association with AIDS related stigma, routine screening of PLWHA for both conditions is recommended. However, more research is required to understand this association.

The association between depression, quality of life, and the health care expenditure of patients with diabetes mellitus in Uganda

BACKGROUND Depression is one of the commonest neuropsychiatric disorders in patients with diabetes mellitus (DM) and is associated with poor glycaemic control, vascular complications, a low quality of life and increased health care expenditure. Co-morbid DM and depression remains poorly identified and inadequately treated in sub-Saharan Africa. METHODS We conducted a cross-sectional survey of 437 patients with DM at 3 DM clinics in Uganda. Participants were assessed for depression, blood sugar levels, diabetic neuropathy, quality of life, and health care expenditures. RESULTS The prevalence of depression was 34.8%. Depressed participants were more likely to be suicidal [OR=3.81, (CI 2.87-5.04)], younger [OR=3.98 CI (1.20-13.23)], un-employed [OR=1.99(CI 1.04-3.81)], and having lost a spouse [OR=2.36 (CI 1.29-4.31)]. Overall quality of life was poor [OR=0.67 (CI 0.47-0.96)], they scored poorer in the physical [OR=0.97, (CI 0.95-0.99)], psychological [OR=1.05 (CI 1.03-1.07)], and environmental [OR=0.97, (CI 0.95-0.99)] domains. They had an increased likelihood of incurring direct out-of-pocket payments for health care services [OR=1.56 (CI 1.03-2.36)], and were more likely to be impoverished [OR=1.52 (CI 1.01-2.28)]. LIMITATION The cross sectional nature of this study makes it difficult to examine causation. More studies are required in order to better understand the associations and impact of the factors examined above on patient outcomes. CONCLUSIONS Depression is highly prevalent among patients with DM in Uganda, and is associated with a number of adverse outcomes. A holistic approach that focuses on the depression management among patients with diabetes is recommended.

Neuropsychiatric perspectives on nodding syndrome in northern Uganda: a case series study and a review of the literature

BACKGROUND Nodding Syndrome (NS), previously called Nodding Disease, is a chronic and debilitating illness affecting thousands of children aged 3-18 years in post-conflict Northern Uganda and South Sudan. Characterised by malnutrition, stunted growth, mental retardation and seizures, some researchers have designated it as epilepsy. With reports appearing in Northern Uganda in1997, NS reached epidemic proportions around 2000-2003 when people were moved into Internally Displaced Peoples (IDP) camps. Investigations for infections (onchocerciasis) and toxins have been inconclusive as to cause, treatment or outcome. No study has addressed the possible relationship of NS to childhood war-trauma experiences. OBJECTIVE To explore a possible relationship of exposure to prolonged war-trauma and the emergence of epidemic NS in Northern Uganda. METHOD This study was a case-series descriptive psychiatric naturalistic field observations of NS cases from homesteads in Northern Uganda and psychiatric investigations and treatment of NS cases referred to Mulago National Referral and Teaching Hospital. RESULTS Detailed Psychiatric clinical evaluations and field observations revealed that NS children had been exposed to severe war-related psychological and physical trauma as well as non-specific CNS insults including untreated CNS infections/infestations and malnutrition possibly causing seizures. Many children suffered post-traumatic stress disorder (PTSD) and depression. CONCLUSION NS could present as an association of childhood complex PTSD, (called Developmental Trauma Disorder), occurring in the chronically war-traumatised children of Northern Uganda, complicated by severe prolonged depression with its characteristic symptoms of psychomotor retardation, anxiety, anhedonia and anorexia. This, coupled with food shortages, resulted in malnutrition, wasting and stunted growth with severe avitaminoses. Many children had seizures. All this calls for multi-disciplinary treatment approaches.

Qualitative study of the influence of antidepressants on the psychological health of patients on antiretroviral therapy in Uganda.

The study set out to explore how HIV-positive individuals conceptualise and describe depression and its manifestation in their lives, and how this may change over time in the context of antiretroviral therapy (ART) and antidepressant treatment. We conducted in-depth interviews using a semi-structured interview guide with 26 adult HIV-positive clients receiving ART in Uganda. We asked the participants to describe their depression and its impact on their general health, physical functioning and psychological wellbeing, as well as the influences of receiving ART or antidepressant treatment. Although depressive experience among the patients was largely described in terms of criteria in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR), some of the symptoms used to describe depression, such as ‘thinking too much’ or worrisome thoughts, did not fit into the DSM-IV criteria. The participants attributed their depression to news of the HIV diagnosis, a fear of dying, the potential socioeconomic consequences of their HIV infection on their family, ART side-effects and continued bad health. Their subjective reports indicated that the treatment of depression with antidepressants had made a positive impact on their general and psychological health. These findings highlight the need for models of HIV care that integrate mental health services and promote the diagnosis and treatment of depression in culturally sensitive ways so as to improve the quality of life and health outcomes for clients. However, keeping the particular study design in mind, these findings should be interpreted as preliminary.

Impact of antidepressant therapy on cognitive aspects of work, condom use, and psychosocial well-being among HIV clients in Uganda.

Objective: Depression has been found to impede several health outcomes among people living with HIV, but little research has examined whether depression treatment mitigates this influence. We assessed the impact of antidepressant therapy on measures of work, condom use, and psychosocial well-being among depressed HIV clients in Uganda. Methods: Paired t-tests and McNemar tests were used to assess change in survey data collected from participants at initiation of antidepressant therapy (baseline) and 6 months later. Results: Ninety-five participants completed the 6-month assessment, of whom 82 (86%) responded to treatment (defined as Patient Health Questionnaire-9 score < 5). Among study completers, work functioning improved significantly, as did measures of self-efficacy related to condom use and work (as well as general self-efficacy), and internalized HIV stigma declined; however, actual engagement in work activity and consistent condom use did not show significant change. Similar findings were observed among treatment responders. Conclusions: Antidepressant treatment benefits functional capacity, psychological well-being, and cognitive intermediary factors that may be essential for behavioral change related to work and condom use, but supplementary therapeutic strategies may be needed to impact more direct behavioral change.

A Structured Protocol Model of Depression Care versus Clinical Acumen: A Cluster Randomized Trial of the Effects on Depression Screening, Diagnostic Evaluation, and Treatment Uptake in Ugandan HIV Clinics

Depression is common among people living with HIV, and it has consequences for both HIV prevention and treatment response, yet depression treatment is rarely integrated into HIV care in sub-Saharan Africa, partly due to the paucity of mental health professionals. We conducted a cluster randomized controlled trial of two task-shifting models to facilitating depression care delivered by medical providers: one that utilized a structured protocol, and one that relied on clinical acumen, in 10 HIV clinics in Uganda. Both models started with routine depression screening of all clients at triage using the 2-item Patient Health Questionnaire (PHQ-2), from which we enrolled 1252 clients (640 at structured protocol clinics, 612 at clinical acumen clinics) who had screened positive over 12 months. We compared the two models on (1) proportion of all client participants, and those clinically depressed (based on survey-administered 9-item PHQ-9>9), who received post-screening evaluation for depression using the PHQ-9; and (2) proportion of clinically depressed who were prescribed antidepressant therapy. Linear probability regression analyses were conducted using a wild cluster bootstrap to control for clustering; patient characteristics, clinic size and time fixed effects were included as covariates. Among all client participants, those in the structured protocol arm were far more likely to have received further evaluation by a medical provider using the PHQ-9 (84% vs. 49%; beta = .33; p = .01). Among the clinically depressed clients (n = 369), the advantage of the structured protocol model over clinical acumen was not statistically significant with regard to PHQ-9 depression evaluation (93% vs. 68%; beta = .21; p = .14) or prescription of antidepressants (69% vs. 58%; beta = .10; p = .50), in part because only 30% of clients who screened positive were clinically depressed. These findings reveal that in both models depression care practices were widely adopted by providers, and depression care reached most depressed clients. The structured protocol model is advantageous for ensuring that positively screened clients receive a depression evaluation, but the two models performed equally well in ensuring the treatment of depressed clients in the context of strong supervision support.

Giving "Sadness" a Name: The Need for Integrating Depression Treatment into HIV Care in Uganda.

Depression is common among people living with HIV/AIDS (PLWHA) in sub-Saharan Africa (SSA), and can have significant consequences for HIV disease progression, treatment response and prevention. Yet mental health services are limited in most HIV care programs in this region, in part due to severe shortages of mental health professionals. To address the need for establishing an effective, sustainable model for integrating depression treatment into HIV care in SSA, we have embarked upon a 3-year research project, INDEPTH Uganda (INtegrating DEPression Treatment and in HIV care in Uganda), to evaluate a task-sharing, protocolized approach to providing antidepressant care in ten HIV clinics in Uganda. In this paper we share our experiences with two treated cases identified during the initial days of implementation, which we believe highlight the potential value and policy implications for task shifting depression care models in under-resourced settings.
