Validity and item response theory properties of the Alcohol Use Disorders Identification Test for primary care alcohol use screening in Mozambique (AUDIT-MZ).

BACKGROUND: No validated tools exist to screen for substance use or dependence in Mozambique. The aim of this study was to validate the Alcohol Use Disorder Identification Test (AUDIT) for use in primary care settings in Mozambique. METHODS: The study administered a final adapted Mozambican 10-item AUDIT (AUDIT-10-MZ) to 502 individuals from antenatal, postpartum, and general outpatient consultations in three Ministry of Health primary health care clinics in Sofala Province, Mozambique. The study evaluated the AUDIT-10-MZ against the MINI 5.0-MZ as a gold standard diagnostic tool. RESULTS: Using the MINI 5.0-MZ, 16 (3.2%) of the sample tested positive for alcohol dependence and 3 (0.6%) tested positive for harmful alcohol use. The full AUDIT-10-MZ had acceptable internal consistency (α = 0.74); however, the shorter AUDIT-C-MZ had a higher alpha value than the full AUDIT screener (α = 0.79). The AUDIT-10-MZ performed well for screening in primary care, achieving areas under the receiver operating characteristic curves (AUROCs) of 0.94 (95% CI: 0.91, 0.96) for alcohol dependence. The AUDIT-C-MZ also performed well with an AUROC of 0.88 (95% CI: 0.80, 0.96) for alcohol dependence. Using a cut-off of ≥6, the AUDIT-10-MZ achieved a sensitivity of 68.8% and specificity of 92.0% for screening for alcohol dependence; a cut-off of ≥3 for the AUDIT-C-MZ achieved a sensitivity of 56.3% and specificity of 90.7%. CONCLUSIONS: Both the AUDIT-10-MZ and AUDIT-C-MZ are valid instruments for screening for alcohol dependence in Mozambique. The AUDIT-C-MZ performed particularly well and providers could use it as a brief screener in primary care settings. Optimal cut-points will depend on weighing false positives and false negatives but could be employed at ≥ 6 or ≥ 7 for the AUDIT-10-MZ and at ≥ 2 or ≥ 3 for the AUDIT-C-MZ. Future implementation research is needed to examine how best to integrate screening for substance use or dependence in primary care settings in Mozambique and other similar LMICs.

The prevalence of hypertension and its distribution by sociodemographic factors in Central Mozambique: a cross sectional study.

BACKGROUND: Hypertension (HTN) is a major risk factor for cardiovascular diseases, and its prevalence has been rising in low- and middle-income countries. The current study describes HTN prevalence in central Mozambique, association between wealth and blood pressure (BP), and HTN monitoring and diagnosis practice among individuals with elevated BP. METHODS: The study used data from a cross-sectional, representative household survey conducted in Manica and Sofala provinces, Mozambique. There were 4101 respondents, aged ≥20 years. We measured average systolic and diastolic BP (SBP and DBP) from three measurements taken in the household setting. Elevated BP was defined as having either SBP ≥140 or DBP ≥90 mmHg. RESULTS: The mean age of the participants was 36.7 years old, 59.9% were women, and 72.5% were from rural areas. Adjusting for complex survey weights, 15.7% (95%CI: 14.0 to 17.4) of women and 16.1% (13.9 to 18.5) of men had elevated BP, and 7.5% (95% CI: 6.4 to 8.7) of the overall population had both SBP ≥140 and DBP ≥90 mmHg. Among participants with elevated BP, proportions of participants who had previous BP measurement and HTN diagnosis were both low (34.9% (95% CI: 30.0 to 40.1) and 12.2% (9.9 to 15.0) respectively). Prior BP measurement and HTN diagnosis were more commonly reported among hypertensive participants with secondary or higher education, from urban areas, and with highest relative wealth. In adjusted models, wealth was positively associated with higher SBP and DBP. CONCLUSIONS: The current study found evidence of positive association between wealth and BP. The prevalence of elevated BP was lower in Manica and Sofala provinces than the previously estimated national prevalence. Previous BP screening and HTN diagnosis were uncommon in our study population, especially among rural residents, individuals with lower education levels, and those with relatively less wealth. As the epidemiological transition advances in Mozambique, there is a need to develop and implement strategies to increase BP screening and deliver appropriate clinical services, as well as to encourage lifestyle changes among people at risk of developing hypertension in near future.

Cascade Analysis: An Adaptable Implementation Strategy Across HIV and Non-HIV Delivery Platforms.

BACKGROUND: Cascades have been used to characterize sequential steps within a complex health system and are used in diverse disease areas and across prevention, testing, and treatment. Routine data have great potential to inform prioritization within a system, but are often inaccessible to frontline health care workers (HCWs) who may have the greatest opportunity to innovate health system improvement. METHODS: The cascade analysis tool (CAT) is an Excel-based, simple simulation model with an optimization function. It identifies the step within a cascade that could most improve the system. The original CAT was developed for HIV treatment and the prevention of mother-to-child transmission of HIV. RESULTS: CAT has been adapted 7 times: to a mobile application for prevention of mother-to-child transmission; for hypertension screening and management and for mental health outpatient services in Mozambique; for pediatric and adolescent HIV testing and treatment, HIV testing in family planning, and cervical cancer screening and treatment in Kenya; and for naloxone distribution and opioid overdose reversal in the United States. The main domains of adaptation have been technical-estimating denominators and structuring steps to be binary sequential steps-as well as logistical-identifying acceptable approaches for data abstraction and aggregation, and not overburdening HCW. DISCUSSION: CAT allows for prompt feedback to HCWs, increases HCW autonomy, and allows managers to allocate resources and time in an equitable manner. CAT is an effective, feasible, and acceptable implementation strategy to prioritize areas most requiring improvement within complex health systems, although adaptations are being currently evaluated.

Barriers to access and adherence to tuberculosis services, as perceived by patients: A qualitative study in Mozambique.

INTRODUCTION: Tuberculosis (TB) continues to be a leading cause of death in Sub-Saharan Africa, including Mozambique. While diagnostic methods and total notifications are improving, significant gaps remain between total numbers of TB cases annually, and the number that are notified. The purpose of this study was to elicit Mozambican patients with drug sensitive TB (DS-TB), TB/HIV and Multi drug resistant tuberculosis (MDR-TB) understanding and assessment of the quality of care for DS-TB, HIV/TB and MDR-TB services in Mozambique, along with challenges to effectively preventing, diagnosing and treating TB. MATERIALS AND METHODS: Qualitative data was collected via separate focus group discussions consisting of patients with DS-TB, TB/HIV and MDR-TB at four health centers in Sofala and Manica Province, Mozambique, to describe knowledge on TB, HIV and MDR-TB, and identify barriers to access and adherence to services and their recommendations for improvement. A total of 51 patients participated in 11 discussions. Content analysis was done and main themes were identified. RESULTS: Focus groups shared a number of prominent themes. Respondents identified numerous challenges including delays in diagnosis, stigma related with diagnosis and treatment, long waits at health facilities, the absence of nutritional support for patients with TB, the absence of a comprehensive psychosocial support program, and the lack of overall knowledge about TB or multi drug resistant TB in the community. DISCUSSION: TB patients in central Mozambique identified many challenges to effectively preventing, diagnosing and treating tuberculosis. Awareness strengthening in the community, continuous quality monitoring and in-service training is needed to increase screening, diagnosis and treatment for TB, HIV/TB and MDR-TB.
