Prevalence of sexually transmitted infections (STIs), associations with sociodemographic and behavioural factors, and assessment of the syndromic management of vaginal discharge in women with urogenital complaints in Mozambique.

In Mozambique, sexually transmitted infections (STIs) are estimated to be prevalent, but diagnosis and treatment of curable STIs rely only on syndromic management. We examined the prevalence of four non-viral STIs and HIV-1/2, based on etiological diagnosis, associations with sociodemographic and behavioural factors, and the STI diagnostic accuracy of the vaginal discharge syndromic management in women with urogenital complaints in Maputo, Mozambique. A cross-sectional study was performed in Maputo, Mozambique, February 2018-January 2019, enrolling 924 women of reproductive age with urogenital complaints. Endocervical/vaginal swabs were sampled and chlamydia, gonorrhoea, trichomoniasis and Mycoplasma genitalium infections were diagnosed using a multiplex real-time PCR (AmpliSens; InterLabServices). Serological testing was performed for HIV-1/2. A structured questionnaire collected metadata. All data were analyzed in STATA/IC 12.1 using descriptive statistics, chi-square tests and logistic regression model. About 40% of the women were less than 24 years old, 50.8% were single, 62.1% had their sexual debut between 12 and 17 years of age, and the main complaint was vaginal discharge syndrome (85%). The prevalence of chlamydia was 15.5%, trichomoniasis 12.1%, gonorrhoea 4.0%, M. genitalium 2.1%, and HIV-1/2 22.3%. The vaginal discharge syndrome flowchart had a sensitivity of 73.0%-82.5% and a specificity of 14%-15% for the detection of any individual non-viral STI in women with urogenital complaints. In total, 19.2% of the symptomatic women with chlamydia, trichomoniasis or gonorrhoea would not be detected and accordingly treated using the vaginal discharge syndromic management (missed treatment) and 70.0% of the women would be treated despite not being infected with any of these three STIs (overtreatment). In conclusion, a high prevalence of especially chlamydia, trichomoniasis, and HIV-1/2 was found in women of childbearing age with urogenital complaints in Maputo, Mozambique. Syndromic management of vaginal discharge revealed low accuracy in the detection of STIs in symptomatic women, especially low specificity, which resulted in under-treatment of STI-positive cases and incorrect or over-treatment of women with urogenital complaints, many of whom were negative for all the non-viral STIs. Etiological diagnosis is imperative for effective management of STIs in symptomatic and asymptomatic women.

Environmental bacterial and fungal contamination in high touch surfaces and indoor air of a paediatric intensive care unit in Maputo Central Hospital, Mozambique in 2018.

Background: The hospital environment serves as a reservoir of microorganisms which may be associated with healthcare-associated infections (HCAI). The study of environmental contamination with microorganisms is a method for the assessment of hospital environmental hygiene. We sought to evaluate the environmental colonisation of a national reference hospital unit, using the total aerobic colony count (ACC) and the isolated microorganisms, as assessment tools. Methods: A cross-sectional study was conducted in the Paediatric Intensive Care Unit (PICU) of the Hospital Central de Maputo during a four-week period in 2018. Surfaces and air were sampled before and after room cleaning, using swabs and passive air method. Those samples were processed at the microbiology laboratory where total ACC levels were evaluated, and microorganisms were isolated, identified and assessed for antibiotic susceptibility. Discussion: Comparison of the total median ACC of the indoor air (287 cfu/m3 before and 195 cfu/m3 after) and surfaces (0.38 cfu/cm2 before and 0.33 cfu/cm2 after) before and after room cleaning did not show significant differences (P>0.05). Microorganisms of epidemiological importance, including coagulase negative staphylococci (CoNS), Klebsiella pneumoniae and Serratia odorifera were isolated and all of these three were multi-drug resistant (MDR). Conclusion: The results showed controlled contamination levels on high touch surfaces in the patient environment and a high level of contamination of the indoor air suggesting deficiencies in the PICU environmental decontamination process. There was evidence of the presence of fungi and MDR species of epidemiological importance in the context of HCAI.

Evaluation of the Mozambique Antiretroviral Therapy (MozART) database as an antiretroviral therapy patient surveillance system, 2017-2018.

Introduction: Mozambique antiretroviral therapy is a database used to monitor patients receiving antiretroviral treatment (ART). This study's objective was to evaluate the system for the purpose to monitor patients receiving ART. Methods: data from 287,052 patients who started ART from January to December 2017 were verified, and retention in care was assessed for 2018 in Mozambique. The Centers for Disease Control and Prevention guidelines for evaluating public health surveillance systems were used to conduct the evaluation. Simplicity, flexibility, data quality, representativeness and stability attributes were evaluated. Results: a total of 93% (266,880/287,052) of patients on ART were adults ≥15 years old, and 65% (186,677/287,052) were female. The system was complex, it involved four organisations and its management was online. Data quality was moderate with 19% (1,533,885/8,037,456) of empty variable fields, 0.04% (123/287,052) observations with birth date later than the initial ART date, 0.2% (424/287,052) and 23% (68,039/287,052) with initial ART date and diagnosis date, later than the next ART pickup date. Nationally, 19%(31/161) of the districts did not have data in the information system. MozART cover health facilities with electronic patient tracking systems. Hence did not represent all patients on ART. While it was not possible to add variables of the electronic patient tracking, the system was stable as neither data or server interruptions were reported. Conclusion: the system was useful, stable, with moderate data quality, complex, not flexible and not representative. We recommend to health facilities and partners to develop and distribute procedures for data validation and completeness and report all patient tracking variables in the system.

Evaluation of the multidrug-resistant tuberculosis surveillance system in Maputo City, Mozambique in the period 2017-2018.

Introduction: multidrug-resistant tuberculosis (MDR-TB) remains a public health problem worldwide. In Mozambique, cases of MDR-TB have increased annually. In 2018, 1,206 cases were reported, as compared to 943 cases in 2017. The aim of this study was to assess the surveillance system for multidrug-resistant tuberculosis in Maputo City. Methods: an extract from the national database was considered for a cut-out of the City of Maputo in the period 2017-2018; the study was conducted per the guidelines of the Centers for Disease Control and Prevention, where the description of the system was carried out, and evaluation of the attributes. Each attribute was evaluated according to the established criteria and parameters. Results: the surveillance system is based on the collection of data in health centers. Four hundred and six cases of MDR-TB were notified, of which 56.8% (231/406) were male and 95.9% (386/406) were ≥15 years. The system was complex with 4 levels of information transmission. With regard to flexibility, there was no changing the variables in the database. Acceptability was good. The quality of the data was regular with discrepancy of data of 14.5%. The system was considered stable as there was no system interruption. Timeliness with case notification monthly. The system sensitivity was 72.9%, the positive predictive value (PPV) was 2.3% and regarding utility the system has fulfilled its objectives. Conclusion: the system was not flexible, the data quality was regular, had moderate sensitivity and low positive predictive value. Continuous assessment of data and scale up the diagnosis for the detection of cases of MDR-TB is recommended.

Evaluation of the health information system for monitoring and evaluating the voluntary medical male circumcision program in Mozambique, 2013-2019.

Introduction: the prevalence of human immunodeficiency virus (HIV) in Mozambique has increased from 11.5% in 2009 to 13.2% in 2015. The Mozambique Ministry of Health (MOH) developed a 5-year strategy (2013-2017) for male voluntary medical circumcision (VMMC) to increase in the provinces where there is the greatest number of HIV. We aimed to evaluate the health information system for monitoring and evaluating VMMC in Mozambique from 2013-2019. Methods: we reviewed the records of the National Health Information System for Monitoring and Evaluation (SIS-MA) database for VMMC of the MOH. The evaluation was based on the updated guidelines for the evaluation of public health surveillance systems of the Centers for Disease Control and Prevention. Results: the coverage rate for VMMC in Mozambique in the period under study was (89%) (1,784,335/2,000,000). The system was expected to circumcise for the year 2019 (162,052) and 390,590 was reached, exceeding the target 241.0% (390,590/162,052). Of the total number of men circumcised, 0.7% (12,391/1,784,335) were HIV-positive (previously tested) and 0.4% (6,382/1,784,335) had a record of adverse events in the period under review (2013-2019). Zambézia Province had the highest VMMC coverage (in numbers) at 16.0% (396,876/2,476,395) while Maputo City had the least 19.7% (107,104/543,096). The system was able to operate both online and offline and continue functioning with introducing new changes (e.g. the new male circumcision complication reporting). Conclusion: the system was representative, flexible, simple, with good data quality and low acceptability. We recommended continuous and routine entry of quality data into the system, guide organizations for improved functioning.
