Abstract Background Limitations of tuberculosis (TB) diagnostic tools and measures restrict proper TB control in places with high drug-resistant TB prevalence. This study aimed to explore gaps in the primary health care (PHC) TB services in Armenia compared to international standards on Assessment of Patients (AOP). Methods We applied mixed methods to assess the AOP standards in 30 outpatient TB centers using observational and documents/medical records review's standardized checklists, in-depth interviews, and focus group discussions. Evaluation was conducted in all 10 regions of Armenia and the capital city Yerevan. Joint Commission International Standards for Ambulatory Care, International Standards for TB Care, and WHO framework, served as a guideline for this assessment. Results PHC physicians are qualified for a set of examinations to diagnose TB. Planned reassessments are conducted continuously, though defined writings for the scope and content of reassessments administered by each clinical discipline is absent. Laboratory departments provide high quality services to the TB patients with the defined timeframes for reporting the results. Laboratory and radiology services staff is qualified and experienced. The biosafety rules are compliant with local and international standards. However, the location and conditions of the laboratory departments are mostly non-compliant with the standards. Lack of modern equipment restricts maintaining proper environmental controls, including ventilation systems. Laboratory technicians have little knowledge of the organization's safety management program and its relation to the laboratory safety program. The facilities have neither formal quality control programs regulated by documents and policies nor an identified radiation safety program protocol. Conclusions On the level of AOP standards, the PHC TB services in Armenia have satisfactory performance. However, assessed standards for this function required certain improvements. Key messages In Armenia, the tuberculosis care in PHC facilities presents high level of compliance for patient assessment international standards. To fully meet the standards, facilities need to reconstructed/renovated laboratories and establish the radiology and diagnostic equipment management, quality control and radiation safety programs.

Abstract Background High quality health promotion (HP) depends on a competent workforce for which professional development programmes for practitioners are essential. The “CompHP Core Competencies Framework in HP” defines crucial competency domains but a recent review concluded that the implementation and use of the framework is lacking. The aim was to develop and validate a self-assessment tool for HP competencies, which should help evaluate training courses. Methods A brief self-assessment tool was employed in 2018 in Austria. 584 participants of 77 training courses submitted their post-course assessment (paper-pencil, RR = 78.1%). In addition, longitudinal data are available for 148 participants who filled in a pre-course online questionnaire. Measurement reliability and validity was tested by single factor, bifactor, multigroup, and multilevel CFA. A SEM proved for predictive and concurrent validity, controlling gender and age. Results A bifactor model (X2/df=3.69, RMSEA=.07, CFI=.95, sRMR=.07) showed superior results with a strong general CompHP factor (FL>.65, wH=.90, ECV=.85), configurally invariant for two training programmes. On course level, there was only minimal variance between trainings (ICC<.08). Structurally, there was a significant increase in HP competencies when comparing pre- and post-course measurements (b=.33, p<.01). Participants showed different levels of competencies due to prior knowledge (b=.38, p<.001) and course format (b=.16, p<.06). The total scale had good properties (m = 49.8, sd = 10.3, 95%-CI: 49.0-50.7) and discriminated between groups (eg by training length). Conclusions The results justify the creation of an overall scale to assess core HP competencies. It is recommended to use the scale for evaluating training courses. The work compensates for the lack of empirical studies on the CompHP concept and facilitates a broader empirical application of a uniform competency framework for HP in accordance with international standards in HP and public health. Key messages The self-assessment tool provides a good and compact foundation for assessing HP competencies. It provides a basis for holistic, high quality and sustainable capacity building or development in HP.

Abstract. The SeaSWIR dataset consists of 137 ASD (Analytical Spectral Devices, Inc.) marine reflectances, 137 Total Suspended Matter (TSM) measurements and 97 turbidity measurements gathered at three turbid estuarine sites (Gironde, La Plata, Scheldt). The dataset is valuable because of the high quality measurements of the marine reflectance in the Short Wave InfraRed I region (SWIR-I: 1000–1200 nm) and SWIR-II (1200–1300 nm) and because of the wide range of TSM concentrations from 48 mg L−1 up to 1400 mg L−1. The ASD measurements were gathered using a detailed measurement protocol and were subjected to a strict quality control. The SeaSWIR marine reflectance is characterized by low reflectance at short wavelengths (

Background The quality of care for tuberculosis (TB) is deficient in high-burden countries and urgently needs improvement. However, comprehensively identifying the required improvements is challenging. Providing high-quality TB care is an important step toward improving patients’ quality of life and decreasing TB morbidity and mortality. Effective tools for assessing the quality of TB services using international standards and guidelines can identify existing gaps in services and inform improvements to ensure high-quality inpatient TB services. Objective This study aimed to develop evaluation instruments for defining the quality of provision of TB services. Methods To assess quality of services in the largest TB hospital in Armenia, we developed instruments based on the Joint Commission International Accreditation Standards for Hospitals, International Standards for TB Care, TB Laboratories Bio-Safety Standards, and the World Health Organization framework for conducting TB program reviews. A mixed methods approach was utilized, triangulating quantitative (checklists) and qualitative (in-depth interviews) results. A scoring system and strengths, weaknesses, opportunities, and treats analysis was applied to detail results for each of the 122 standards assessed. A scaling approach was used to present overall performances of inpatient services for eight patient-centered functions and five organization management functions. Results Overall, 40 in-depth interviews and 91 checklists (21 observations, 16 policy papers, 20 staff qualification documents, and 34 medical records) were developed, utilized, and analyzed to explore practices of health care professionals, assess inpatient treatment experience of patients and their family members, evaluate facility environmental conditions, and define the degree of compliance to standards. Conclusions The effective comprehensive evaluation instruments and methods developed in this study for quality of inpatient TB services support the implementation of similar effective assessments in other countries. It may also become a platform to develop similar approaches for assessing ambulatory TB services in resource-limited countries. International Registered Report Identifier (IRRID) DERR1-10.2196/13903

Abstract This study examines the extent to which Jordan is committed to principles of compulsory and free basic education, by analyzing legislation in light of constitutional and international standards regarding the right to education. Methodology includes quantitative assessment of these principles using a questionnaire distributed to students and their teachers in a number of public schools in three Jordanian governorates. Three focus group sessions composed of students and their teachers were held. The study suggests that, whilst the Jordanian Constitution has explicitly adopted such principles, Jordanian law yet includes provisions that diminish providing free basic education to all children of compulsory age and that mitigate the number of students who drop out of school. This study proposes amending the title of Chapter II of the Constitution and Article 20 to ensure that all children living in Jordan enjoy the right to education.

Abstract Background Opsonophagocytic assays (OPAs) are an important tool for assessing vaccine-induced functional antibody responses. OPAs are complex assays composed of many biological components (eg serum, complement sources, bacteria, and human phagocytes) which contribute to assay variability and may result in titer drift if not carefully controlled. Rigorous development and validation coupled with routine monitoring of assay performance are required to ensure that high-quality OPA serological data are consistently generated throughout the lifetime of existing and next-generation pneumococcal vaccines. Methods OPA specificity was demonstrated by competing functional antibody activity with pneumococcal polysaccharides. Assay qualification/validation assessed accuracy, precision, and sample linearity. Assay performance over time was assessed through the implementation of quality control serum data tracking systems and longterm serum proficiency panels that are routinely tested during assay performance. Human quality control sera are included on each assay plate to ensure that each plate meets pre-specified acceptance criteria. Proficiency serum panels are comprised of individual human serum samples derived from subjects immunized with pneumococcal vaccines and are used to monitor performance across a range of serological titers and over time. Results The OPAs were shown to be specific and reproducible. Monitoring of assay performance over time demonstrated that the assays are stable. For the 13 serotypes contained in 13vPnC reliable titers have been generated in over a decade of testing which is an essential prerequisite in the evaluation of next-generation pneumococcal conjugate vaccines such as 20vPnC, whose licensure depends on demonstration of non-inferiority to 13vPnC. Conclusion Maintenance and careful monitoring of high-quality assays to measure functional antibody responses, such as OPAs, is critical for the delivery of reliable serological data to support the advancement of pneumococcal vaccine programs. Pneumococcal OPAs must be rigorously maintained to ensure continuity of serological data over time and inform licensure decisions of next-generation vaccines as well as postmarketing and seroepidemiology studies.
