Investigating Barriers to Tuberculosis Evaluation in Uganda Using Geographic Information Systems.

ABSTRACT: Reducing geographic barriers to tuberculosis (TB) care is a priority in high-burden countries where patients frequently initiate, but do not complete, the multi-day TB evaluation process. Using routine cross-sectional study from six primary-health clinics in rural Uganda from 2009 to 2012, we explored whether geographic barriers affect completion of TB evaluation among adults with unexplained chronic cough. We measured distance from home parish to health center and calculated individual travel time using a geographic information systems technique incorporating roads, land cover, and slope, and measured its association with completion of TB evaluation. In 264,511 patient encounters, 4,640 adults (1.8%) had sputum smear microscopy ordered; 2,783 (60%) completed TB evaluation. Median travel time was 68 minutes for patients with TB examination ordered compared with 60 minutes without (P < 0.010). Travel time differed between those who did and did not complete TB evaluation at only one of six clinics, whereas distance to care did not differ at any of them. Neither distance nor travel time predicted completion of TB evaluation in rural Uganda, although limited detail in road and village maps restricted full implementation of these mapping techniques. Better data are needed on geographic barriers to access clinics offering TB services to improve TB diagnosis.

Project description:BACKGROUND:The World Health Organization recommends strategies to improve urban design, public transportation, and recreation facilities to facilitate physical activity for non-communicable disease prevention for an increasingly urbanized global population. Most evidence supporting environmental associations with physical activity comes from single countries or regions with limited variation in urban form. This paper documents variation in comparable built environment features across countries from diverse regions. METHODS:The International Physical Activity and the Environment Network (IPEN) study of adults aimed to measure the full range of variation in the built environment using geographic information systems (GIS) across 12 countries on 5 continents. Investigators in Australia, Belgium, Brazil, Colombia, the Czech Republic, Denmark, China, Mexico, New Zealand, Spain, the United Kingdom, and the United States followed a common research protocol to develop internationally comparable measures. Using detailed instructions, GIS-based measures included features such as walkability (i.e., residential density, street connectivity, mix of land uses), and access to public transit, parks, and private recreation facilities around each participant's residential address using 1-km and 500-m street network buffers. RESULTS:Eleven of 12 countries and 15 cities had objective GIS data on built environment features. We observed a 38-fold difference in median residential densities, a 5-fold difference in median intersection densities and an 18-fold difference in median park densities. Hong Kong had the highest and North Shore, New Zealand had the lowest median walkability index values, representing a difference of 9 standard deviations in GIS-measured walkability. CONCLUSIONS:Results show that comparable measures can be created across a range of cultural settings revealing profound global differences in urban form relevant to physical activity. These measures allow cities to be ranked more precisely than previously possible. The highly variable measures of urban form will be used to explain individuals' physical activity, sedentary behaviors, body mass index, and other health outcomes on an international basis. Present measures provide the ability to estimate dose-response relationships from projected changes to the built environment that would otherwise be impossible.

Project description:BackgroundNumerous studies have revealed widespread clinician frustration with the usability of electronic health records (EHRs) that is counterproductive to adoption of EHR systems to meet the aims of health-care reform. With poor system usability comes increased risk of negative unintended consequences. Usability issues could lead to user error and workarounds that have the potential to compromise patient safety and negatively impact the quality of care.[1] While there is ample research on EHR usability, there is little information on the usability of laboratory information systems (LISs). Yet, LISs facilitate the timely provision of a great deal of the information needed by physicians to make patient care decisions.[2] Medical and technical advances in genomics that require processing of an increased volume of complex laboratory data further underscore the importance of developing user-friendly LISs. This study aims to add to the body of knowledge on LIS usability.MethodsA survey was distributed among LIS users at hospitals across the United States. The survey consisted of the ten-item System Usability Scale (SUS). In addition, participants were asked to rate the ease of performing 24 common tasks with a LIS. Finally, respondents provided comments on what they liked and disliked about using the LIS to provide diagnostic insight into LIS perceived usability.ResultsThe overall mean SUS score of 59.7 for the LIS evaluated is significantly lower than the benchmark of 68 (P < 0.001). All LISs evaluated received mean SUS scores below 68 except for Orchard Harvest (78.7). While the years of experience using the LIS was found to be a statistically significant influence on mean SUS scores, the combined effect of years of experience and LIS used did not account for the statistically significant difference in the mean SUS score between Orchard Harvest and each of the other LISs evaluated.ConclusionsThe results of this study indicate that overall usability of LISs is poor. Usability lags that of systems evaluated across 446 usability surveys.

Project description:BackgroundAccessing surgical repair poses challenges to women living with female genital fistula who experience intersectional vulnerabilities including poverty, gender, stigma and geography. Barriers to fistula care have been described qualitatively in several low- and middle-income countries, but limited effort has been made to quantify these factors. This study aimed to develop and validate composite measures to assess barriers to accessing fistula repair in Nigeria and Uganda.MethodsThis quantitative study built on qualitative findings to content validate composite measures and investigates post-repair client surveys conducted at tertiary hospitals in Northern and Southern Nigeria and Central Uganda asking women about the degree to which a range of barriers affected their access. An iterative scale development approach included exploratory and confirmatory factor analyses of two samples (n = 315 and n = 142, respectively) using STATA 13 software. Reliability, goodness-of-fit, and convergent and predictive validity were assessed.ResultsA preliminary 43-item list demonstrated face and content validity, triangulated with qualitative data collected prior to and concurrently with survey data. The iterative item reduction approach resulted in the validation of a set of composite measures, including two indices and three sub-scales. These include a Financial/Transport Inaccessibility Index (6 items) and a multidimensional Barriers to Fistula Care Index of 17 items comprised of three latent sub-scales: Limited awareness (4 items), Social abandonment (6 items), and Internalized stigma (7 items). Factor analyses resulted in favorable psychometric properties and good reliability across measures (ordinal thetas: 0.70-0.91). Higher levels of barriers to fistula care are associated with a woman living with fistula for longer periods of time, with age and geographic settings as potential confounders.ConclusionsThis set of composite measures that quantitatively captures barriers to fistula care can be used separately or together in research and programming in low- and middle-income countries.
