Monitoring retention in care: using multiple laboratory tests as an indicator for HIV medical care.

Retention in care is an important strategy for HIV prevention. Unfortunately, surveillance systems were not designed to capture face-to-face visits with HIV health care providers to assess retention in care. Instead, HIV-related laboratory tests are used as a surrogate measure. This study estimated the sensitivity (90%) and specificity (28%) of two HIV-related laboratory tests separated by at least 90 days for two face-to-face visits among people receiving HIV-related health care in Oregon. Overall accuracy of the surrogate was good but slightly overestimated the proportion of people living with HIV/AIDS actually retained in care.

Imagining and implementing healthy city interventions: Combined results from parallel concept mapping exercises in Montreal with community members and stakeholders.

OBJECTIVE: Built environment interventions provide structural solutions to complex urban challenges. Though community voices are part of municipal decision-making, planners and public health professionals need tools to better integrate their perspectives for desired changes (what) when implementing built environment interventions (how). We present two simultaneous concept mapping exercises conducted in Montréal, Canada, to facilitate the consideration of these dimensions. METHODS: Community members were prompted about neighbourhood changes that could improve their quality of life; stakeholders were prompted about factors that contribute to successful implementation of interventions. Through each exercise, items were generated, grouped, and rated on importance and feasibility. Concept maps were produced using multidimensional scaling and hierarchical cluster analysis. The clusters identified by community members and stakeholders were combined into a Community × Stakeholder Matrix, which supported discussions on interventions with the research's Advisory Committee. RESULTS: Thirty-two community members generated 41 responses, which resulted in 6 clusters: (1) strengthen public transportation, (2) reduce space dedicated to cars, (3) foster local social connections, (4) develop quality cycling infrastructure, (5) improve pedestrian accessibility, and (6) green the city. Thirty-seven stakeholders generated 40 items, which resulted in 5 clusters: (1) collaboration with stakeholders and citizens, (2) planning and evaluation, (3) common vision for the future, (4) regulatory framework and funding, and (5) context-informed approach. CONCLUSION: Capturing the collective vision of our urban environments and the processes underlying change through concept mapping can lead to more successful changes. We propose combining understandings of the what and how into a matrix to support evaluation and strategic planning of interventions and better integrate community voices into operational planning.

RéSUMé: OBJECTIF: Les interventions sur le cadre bâti peuvent offrir des solutions structurelles aux défis urbains complexes. Bien que les communautés fassent partie du processus décisionnel municipal, les urbanistes et les professionnels de la santé publique ont besoin d'outils pour mieux intégrer leurs perspectives sur les changements souhaités (le quoi) dans la mise en œuvre réussie des programmes et des interventions sur l'environnement bâti (le comment). Nous présentons deux exercices simultanés de cartographie conceptuelle menés à Montréal, Canada, visant à capter ces dimensions de mise en œuvre. MéTHODES: Les membres de la communauté ont été sondés sur les changements dans leur quartier qui seraient susceptibles d'améliorer leur qualité de vie, tandis que des acteurs municipaux ont été sondés sur les facteurs qui contribuent à la réussite de la mise en œuvre des interventions urbaines. Pour chaque exercice, des items ont été générés, regroupés et notés en fonction de leur importance et de leur faisabilité. Des cartes conceptuelles ont été produites à l'aide d'analyse multivariée d'étalonnage multidimensionnel et d'une analyse hiérarchique ascendante. Les regroupements identifiés par les membres de la communauté et les acteurs municipaux ont été combinés dans une matrice communauté × acteurs municipaux, qui a encadré une discussion sur les interventions sur le cadre bâti avec le comité consultatif du programme de recherche. RéSULTATS: Trente-deux membres de la communauté ont généré 41 réponses uniques, qui ont formé 6 regroupements : (1) renforcer les transports en commun, (2) réduire l'espace dédié aux voitures, (3) favoriser le lien social local, (4) développer des infrastructures cyclables de qualité, (5) améliorer l'accessibilité piétonne, et (6) verdir la ville. Trente-sept acteurs municipaux ont généré 40 éléments uniques, qui ont mené à 5 regroupements : (1) collaboration avec les parties prenantes et les citoyens, (2) planification et évaluation, (3) vision commune pour l'avenir, (4) cadre réglementaire et financement, et (5) approche contextuelle. CONCLUSION: En captant la vision collective sur nos environnements urbains et la compréhension des processus sous-jacents au changement avec la cartographie conceptuelle, les transformations urbaines peuvent être plus réussies et plus inclusives. Nous proposons de combiner les perspectives sur le quoi et le comment dans une matrice pour soutenir l'évaluation et la planification stratégique d'interventions, tout en promouvant l'intégration des voix de la communauté dans la planification opérationnelle de l'aménagement urbain.

Female Inmates with Diabetes: Results from Changes in a Prison Food Environment.

OBJECTIVE: The prevalence of diabetes among Oregon prison inmates has increased by 50% in the last 5 years. The Healthy Food Access Project (HFAP) was implemented in the minimum-security facility at the Oregon Coffee Creek Correctional Facility to reduce the risk of chronic disease (including diabetes) and improve nutrition among female prison inmates. The intervention reduced the menu from 3,000 to 2,200 calories per day and provided nutrition education. We evaluated the effectiveness of HFAP on female inmates with diabetes on two outcomes: the effect of the reduced calorie menu on glycemic control and other biometric measures, and the calories purchased from commissary foods. METHOD: We conducted a quasiexperimental study among all female inmates with diabetes living at the prison on August 28, 2013. Exposed inmates resided in the minimum-security facility for a minimum of 90 days after August 1, 2012 (when a reduced calorie menu was implemented); unexposed inmates resided primarily or exclusively in the medium-security facility. Medical chart abstractions were conducted to collect biometric data and mixed effects models described the differences in biometric trends between exposed and unexposed participants. Commissary receipts were collected to measure calories purchased. RESULTS: Of the 63 female inmates with diabetes, 24 were exposed to the intervention and 39 were unexposed. Exposed inmates reduced their hemoglobin A1c levels by 0.04 percentage points per month compared with 0.01 percentage points per month among unexposed inmates. Changes in body mass index depended on the amount of time they had served at the prison. Participants purchased an average of 1,094 calories from the commissary per day. Exposed inmates did not purchase more calories from the commissary after HFAP implementation. CONCLUSION: Exposure to HFAP supported modest improvement in glycemic control among female inmates with diabetes, and inmates exposed to HFAP did not purchase more calories from the commissary.
