Evaluation of the National Human Immunodeficiency Virus Surveillance System for the 2011 diagnosis year.

ABSTRACT: In 2009, the Centers for Disease Control and Prevention completed migration of all 59 surveillance project areas (PAs) from the case-based HIV/AIDS Reporting System to the document-based Enhanced HIV/AIDS Reporting System.We conducted a PA-level assessment of Enhanced HIV/AIDS Reporting System process and outcome standards for HIV infection cases.Process standards were reported by PAs and outcome standards were calculated using standardized Centers for Disease Control and Prevention SAS code.A total of 59 PAs including 50 US states, the District of Columbia, 6 separately funded cities (Chicago, Houston, Los Angeles County, New York City, Philadelphia, and San Francisco), and 2 territories (Puerto Rico and the Virgin Islands).Cases diagnosed or reported to the PA surveillance system between January 1, 2011, and December 31, 2011, using data collected through December 2012.Process standards for death ascertainment and intra- and interstate case de-duplication; outcome standards for completeness and timeliness of case reporting, data quality, intrastate duplication rate, risk factor ascertainment, and completeness of initial CD4 and viral load reporting.Fifty-five of 59 PAs (93%) reported linking cases to state vital records death certificates during 2012, 76% to the Social Security Death Master File, and 59% to the National Death Index. Seventy percent completed monthly intrastate, and 63% completed semiannual interstate de-duplication. Eighty-three percent met the 85% or more case ascertainment standard, and 92% met the 66% or more timeliness standard; 75% met the 97% or more data quality standard; all PAs met the 5% or less intrastate duplication rate; 41% met the 85% or more risk factor ascertainment standard; 90% met the 50% or more standard for initial CD4; and 93% met the same standard for viral load reporting. Overall, 7% of PAs met all 11 process and outcome standards.Findings support the need for continued improvement in HIV surveillance activities and monitoring of system outcomes.

Project description:BACKGROUND:Over the past decade, influenza surveillance has been established in several African countries including Zambia. However, information on the on data quality and reliability of established influenza surveillance systems in Africa are limited. Such information would enable countries to assess the performance of their surveillance systems, identify shortfalls for improvement and provide evidence of data reliability for policy making and public health interventions. METHODS:We used the Centers for Disease Control and Prevention guidelines to evaluate the performance of the influenza surveillance system (ISS) in Zambia during 2011-2017 using 9 attributes: (i) data quality and completeness, (ii) timeliness, (iii) representativeness, (iv) flexibility, (v) simplicity, (vi) acceptability, (vii) stability, (viii) utility, and (ix) sustainability. Each attribute was evaluated using pre-defined indicators. For each indicator we obtained the proportion (expressed as percentage) of the outcome of interest over the total. A scale from 1 to 3 was used to provide a score for each attribute as follows: <?60% (as obtained in the calculation above) scored 1 (weak performance); 60-79% scored 2 (moderate performance); ?80% scored 3 (good performance). An overall score for each attribute and the ISS was obtained by averaging the scores of all evaluated attributes. RESULTS:The overall mean score for the ISS in Zambia was 2.6. Key strengths of the system were the quality of data generated (score: 2.9), its flexibility (score: 3.0) especially to monitor viral pathogens other than influenza viruses, its simplicity (score: 2.8), acceptability (score: 3.0) and stability (score: 2.6) over the review period and its relatively low cost ($310,000 per annum). Identified weaknesses related mainly to geographic representativeness (score: 2.0), timeliness (score: 2.5), especially in shipment of samples from remote sites, and sustainability (score: 1.0) in the absence of external funds. CONCLUSIONS:The system performed moderately well in our evaluation. Key improvements would include improvements in the timeliness of samples shipments and geographical coverage. However, these improvements would result in increased cost and logistical complexity. The ISSS in Zambia is largely reliant on external funds and the acceptability of maintaining the surveillance system through national funds would require evaluation.

Project description:The National AIDS Program in Jordan has faced numerous challenges, including insufficient funding, limited resources, and complexities brought on by refugee influxes. The absence of a reliable HIV/AIDS surveillance system further complicates tracking and responding to the epidemic. This study aimed to evaluate the performance and functionality of the National AIDS Program and the HIV/AIDS surveillance system. A qualitative study was conducted to evaluate the National AIDS Program and the HIV/AIDS Surveillance System in Jordan. The study involved 14 key informants specialized in HIV/AIDS Surveillance Systems. Interviews were guided by an interview guide based on the Updated Centers for Disease Control and Prevention Guidelines for Evaluating Public Health Surveillance Systems. Data analysis was performed through directed content analysis. The Voluntary Counseling and Testing Center in Jordan confronts multiple challenges, including poor infrastructure, limited accessibility, and inadequate facilities. Additionally, there is a lack of effective coordination between the Voluntary Counseling and Testing center and the Chest Diseases and Migrant Health Directorate, particularly regarding testing for Tuberculosis. HIV screening in Jordan is hindered by various factors, including disease sensitivity. Voluntary Counseling and Testing lacks HIV/AIDS specialists AND staff adequate training and fails to adhere to updated treatment guidelines. Persistent deficiencies in human resources, equipment, and training continue to plague the HIV/AIDS Surveillance System. Key informants expressed dissatisfaction with the data's usefulness, citing concerns over poor data quality. The data were seldom used for prioritizing resources, identifying at-risk individuals, assessing HIV/AIDS risk factors, or evaluating prevention and control measures. The National AIDS Program and HIV/AIDS Surveillance System activities in Jordan are unstructured, poorly coordinated, and inefficient. Many gaps related to National AIDS Program and HIV/AIDS Surveillance System performance and data were identified. Recommendations include developing an electronic surveillance system for data collection, notification, and reporting, and building the capacities of HIV/AIDS healthcare providers in screening, diagnosis, and management.
