A Systematic Approach to Evidence-Based Design for Measurable Health and Wellness Outcomes: Curating and Translating Evidence to Practice.

OBJECTIVES: Evaluating evidence from peer-review literature for use in evidence-based design is often challenging for the design disciplines, requiring access to the peer-reviewed literature, expertise in evaluating methods and findings, and translating the results into actionable design and operational recommendations. PURPOSE: The purpose of this methods paper is to elucidate the process for systematic evaluation of research to translate evidence into practical application to improve design for occupant health and wellness. BACKGROUND: Researchers have found strong connections in environmental design influence on health and wellness that have proven to be substantiative in the effort to improve health and well-being. Design has the capacity to encourage healthy choices and decisions within the built environment. Translation of evidence into applied design solutions may improve public health. METHODS: A protocol is presented that culminates in the translation of evidence into design recommendations focused on improving occupant health. The protocol includes preparation for the literature search and review, search strategy, study selection, data analysis, and development of the literature review. RESULTS: After evaluation of the evidence is completed, there were several positive findings in the example that stakeholders could utilize to improve the health of building occupants with programs and design to support nutrition, physical activity, and circadian entrainment. CONCLUSIONS: There are a variety of software tools and processes to utilize in the curation of evidence to improve the built environment with relevant design recommendations and operational considerations affecting the personal, social, and economic health of our society.

Decontamination of metals from firefighter turnout gear.

Firefighters are exposed to many different contaminants during structural fires. Moreover, if their protective gear is not successfully decontaminated, firefighters are at risk of being repeatedly exposed to contaminants from previous fires. Thus, the successful removal of contaminants from firefighter turnout gear is necessary to prevent or reduce repeated exposure risks. Laundering methods can reduce the probability of re-exposure to contaminants, such as heavy metals, thus reducing repeated exposure risks. In this study, the efficiencies of heavy metal removal from the firefighter turnout gear outer textile by Decon7 cleaning solution and a standard reference detergent were compared. Nitric acid digests were used to extract metals from textile samples, which were cut from small sections of firefighter jackets, before and after their laundering with either cleaning solution. Inductively coupled plasma mass spectrometry (ICP-MS) was utilized to determine metal contents, including arsenic (As), antimony (Sb), cadmium (Cd), chromium (Cr), and lead (Pb) concentrations. Results from multiplicate samples indicated that, on average, Decon7 was significantly more efficient than a standard detergent in decreasing the concentrations of the five metals studied herein.

Validation of Cardiovascular End Points Ascertainment Leveraging Multisource Electronic Health Records Harmonized Into a Common Data Model in the ADAPTABLE Randomized Clinical Trial.

BACKGROUND: The ADAPTABLE trial (Aspirin Dosing: A Patient-Centric Trial Assessing Benefits and Long-Term Effectiveness) is the first randomized trial conducted within the National Patient-Centered Clinical Research Network to use the electronic health record data formatted into a common data model as the primary source of end point ascertainment, without confirmation by standard adjudication. The objective of this prespecified study is to assess the validity of nonfatal end points captured from the National Patient-Centered Clinical Research Network, using traditional blinded adjudication as the gold standard. METHODS: A total of 15 076 participants with established atherosclerotic cardiovascular disease were randomized to two doses of aspirin (81 mg and 325 mg once daily). Nonfatal end points (hospitalization for nonfatal myocardial infarction, nonfatal stroke, and major bleeding requiring transfusion of blood products) were captured with the use of programming algorithms applied to National Patient-Centered Clinical Research Network data. A random subset of end points was independently reviewed by a disease-specific expert adjudicator. The positive predictive value of the programming algorithms were calculated separately for end points listed as primary and as nonprimary diagnoses. RESULTS: A total of 225 end points were identified (91 myocardial infarction events, 89 stroke events, and 45 bleeding events), including 142 (63%) that were listed as primary diagnoses. Complete source documents were missing for 14% of events. The positive predictive value were 90%, 72%, and 93% for hospitalizations for myocardial infarction, stroke, and major bleeding, respectively, as compared to adjudication. When only primary diagnoses were considered, positive predictive value were 93%, 91%, and 97%, respectively. When only nonprimary diagnoses were considered, positive predictive value were 82%, 36%, and 71%. CONCLUSIONS: As compared with blinded adjudication, clinical end point ascertainment from queries of the National Patient-Centered Clinical Research Network distributed harmonized data was valid to identify hospitalizations for myocardial infarction in ADAPTABLE. The proportion of contradicted events was high for hospitalizations for bleeding and strokes when nonprimary diagnoses were analyzed, but not when only primary diagnoses were considered.

Bacteria Associated with Healthcare-Associated Infections on Environmental Samples Obtained from Two Fire Departments.

(1) Background: Firefighters spend about 64% of their time responding to medical emergencies and providing medical care without a patient history, which can render them vulnerable to healthcare-associated infections (HAI). Infection prevention, control, and surveillance systems have been instituted at hospitals. However, the prevalence of firefighters' exposure to HAI is unknown. The objective of this study was to document evidence of HAI on surfaces in fire stations and engines to inform disinfection procedures and identify which pathogens might contribute to occupational exposures. (2) Methods: High-touch or high-use surfaces of two fire departments were sampled during five separate occasions. One fire station from one fire department was sampled over a 4-week period, whereas four fire stations were sampled from a different fire department only once. Sampled surfaces included: entryway floor, washing machine, medical bag, back seat of engine, keyboard of reporting computer, engine console, and uniform pants. (3) Results: Multiple statistical models determined that bacterial contamination was similar between the two fire departments and their stations. Keyboards were the most contaminated surface for all fire stations and departments, E. coli was the most common bacteria detected, and C. difficile was the least detected bacteria. Adjustments for rates of contamination found that contamination rates varied between fire stations. (4) Conclusions: Comprehensive environmental sampling and clinical studies are needed to better understand occupational exposures of firefighters to HAI.

Comparative Effectiveness of Aspirin Dosing in Cardiovascular Disease.

BACKGROUND: The appropriate dose of aspirin to lower the risk of death, myocardial infarction, and stroke and to minimize major bleeding in patients with established atherosclerotic cardiovascular disease is a subject of controversy. METHODS: Using an open-label, pragmatic design, we randomly assigned patients with established atherosclerotic cardiovascular disease to a strategy of 81 mg or 325 mg of aspirin per day. The primary effectiveness outcome was a composite of death from any cause, hospitalization for myocardial infarction, or hospitalization for stroke, assessed in a time-to-event analysis. The primary safety outcome was hospitalization for major bleeding, also assessed in a time-to-event analysis. RESULTS: A total of 15,076 patients were followed for a median of 26.2 months (interquartile range [IQR], 19.0 to 34.9). Before randomization, 13,537 (96.0% of those with available information on previous aspirin use) were already taking aspirin, and 85.3% of these patients were previously taking 81 mg of daily aspirin. Death, hospitalization for myocardial infarction, or hospitalization for stroke occurred in 590 patients (estimated percentage, 7.28%) in the 81-mg group and 569 patients (estimated percentage, 7.51%) in the 325-mg group (hazard ratio, 1.02; 95% confidence interval [CI], 0.91 to 1.14). Hospitalization for major bleeding occurred in 53 patients (estimated percentage, 0.63%) in the 81-mg group and 44 patients (estimated percentage, 0.60%) in the 325-mg group (hazard ratio, 1.18; 95% CI, 0.79 to 1.77). Patients assigned to 325 mg had a higher incidence of dose switching than those assigned to 81 mg (41.6% vs. 7.1%) and fewer median days of exposure to the assigned dose (434 days [IQR, 139 to 737] vs. 650 days [IQR, 415 to 922]). CONCLUSIONS: In this pragmatic trial involving patients with established cardiovascular disease, there was substantial dose switching to 81 mg of daily aspirin and no significant differences in cardiovascular events or major bleeding between patients assigned to 81 mg and those assigned to 325 mg of aspirin daily.

Chemical exposures from upholstered furniture with various flame retardant technologies.

Upholstered furniture is often manufactured with polyurethane foam (PUF) containing flame retardants (FRs) to prevent the risk of a fire and/or to meet flammability regulations, however, exposure to certain FRs and other chemicals have been linked to adverse health effects. This study developed a new methodology for evaluating volatile organic compound (VOC) and FR exposures to users of upholstered furniture by simulating use of a chair in a controlled exposure chamber and assessing the health significance of measured chemical exposure. Chairs with different fire-resistant technologies were evaluated for VOC and FR exposures via inhalation, ingestion, and dermal contact exposure routes. Data show that VOC exposure levels are lower than threshold levels defined by the US and global indoor air criteria. Brominated FRs were not detected from the studied chairs. The organophosphate FRs added to PUF were released into the surrounding air (0.4 ng/m3 ) and as dust (16 ng/m2 ). Exposure modeling showed that adults are exposed to FRs released from upholstered furniture mostly by dermal contact and children are exposed via dermal and ingestion exposure. Children are most susceptible to FR exposure/dose (2 times higher average daily dose than adults) due to their frequent hand to mouth contact.

SARS-CoV-2 Viability on 16 Common Indoor Surface Finish Materials.

AIM: This study investigated the stability of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on 16 common environmental surface materials. BACKGROUND: SARS-CoV-2 is the causative agent of severe coronavirus disease, a significant public health concern that quickly led to a pandemic. Contamination of environmental surface materials is of concern, with previous studies identifying long-term detection of infectious particles on surfaces. These contaminated surfaces create an increased risk for contact transmission. METHODS: Surface materials were inoculated with 10,000 plaque forming units and samples were collected 4, 8, 12, 24, 30, 48, and 168 hours post infection (hpi). Viral titers were determined for each sample and time point using plaque assays. Nonparametric modeling utilized the Turnbull algorithm for interval-censored data. Maximum likelihood estimates for the survival curve were calculated. Parametric proportional hazards regression models for interval censored data were used to explore survival time across the surface materials. RESULTS: There was a sharp decline in recoverable virus after 4 hpi for all tested surfaces. By 12 hpi, infectious SARS-CoV-2 was recoverable from only four surfaces; and by 30 hr, the virus was recoverable from only one surface. There were differences in survival curves based on the materials although some groups of materials are similar, both statistically and practically. CONCLUSIONS: While very low amounts of infectious SARS-CoV-2 are recoverable over time, there remains a risk of viral transmission by surface contamination in indoor environments. Individuals and institutions must follow appropriate procedures to decontaminate indoor environment and increase diligence for hand hygiene and personal protective equipment.

Indoor Finish Material Influence on Contamination, Transmission, and Eradication of Methicillin-Resistant Staphylococcus aureus (MRSA).

OBJECTIVE: The purpose of this study was to evaluate environmental surface materials used in healthcare environments for material composition, methicillin-resistant Staphylococcus aureus (MRSA) viability, and a comparison of two disinfectants, a bleach germicidal cleaner and Decon7, a novel disinfectant. BACKGROUND: Contaminated environmental surfaces have been associated with outbreaks of healthcare-associated illness (HAIs). One in every 20 patients in U.S. acute care hospitals acquire a healthcare-associated illness, leading to consequences such as elevated morbidity, mortality, and a decrease in quality of life. In the patient environment, MRSA can remain viable from hours to up to 14 days. METHODS: Environmental surface materials were evaluated as new and worn. Material composition and properties were assessed to evaluate surface integrity and the influence on the disinfection of MRSA. Inoculated materials were used to assess MRSA viability over time and the efficacy of a manufacturer's recommended cleaning and disinfection product compared to a novel disinfectant. RESULTS: Environmental surface materials respond differently in appearance and roughness, when mechanically worn. When measuring MRSA survival, at 24 hr, MRSA colony forming unit (CFU) counts were reduced on the copper sheet surface and solid surface with cupric oxide. By 72 hr, all MRSA counts were zero. Bleach and the novel disinfectant were equally effective at disinfecting MRSA from all surface types. CONCLUSIONS: This study highlights a gap in knowledge about the impact of type and wear of environmental surface materials used in healthcare environments on contamination with epidemiologically important organisms. In conclusion, environmental surface material wear, properties, and cleaning and disinfection efficacy are important factors to consider when addressing HAIs.

Healthy Behaviors through Behavioral Design-Obesity Prevention.

Evidence for behavior modification for improved health outcomes was evaluated for nutrition, physical activity (PA), and indoor environmental quality (IEQ). The databases searched included LISTA, PubMed, and Web of Science, with articles rated using an a priori baseline score of 70/100 to establish inclusion. The initial search produced 52,847 articles, 63 of which were included in the qualitative synthesis. Thirteen articles met inclusion for nutrition: cafeteria interventions, single interventions, and vending interventions. Seventeen articles on physical activity were included: stair use, walking, and adjustable desks. For IEQ, 33 articles met inclusion: circadian disruption, view and natural light, and artificial light. A narrative synthesis was used to find meaningful connections across interventions with evidence contributing to health improvements. Commonalities throughout the nutrition studies included choice architecture, increasing the availability of healthy food items, and point-of-purchase food labeling. Interventions that promoted PA included stair use, sit/stand furniture, workplace exercise facilities and walking. Exposure to natural light and views of natural elements were found to increase PA and improve sleep quality. Overexposure to artificial light may cause circadian disruption, suppressing melatonin and increasing risks of cancers. Overall, design that encourages healthy behaviors may lower risks associated with chronic disease.

The Significance of Harm Reduction as a Social and Health Care Intervention for Injecting Drug Users: An Exploratory Study of a Needle Exchange Program in Fresno, California.

Infectious disease remains a significant social and health concern in the United States. Preventing more people from contracting HIV/AIDS or Hepatitis C (HCV), requires a complex understanding of the interconnection between the biomedical and social dimensions of infectious disease. Opiate addiction in the US has skyrocketed in recent years. Preventing more cases of HIV/AIDS and HCV will require dealing with the social determinants of health. Needle exchange programs (NEPs) are based on a harm reduction approach that seeks to minimize the risk of infection and damage to the user and community. This article presents an exploratory small-scale quantitative study of the injection drug using habits of a group of injection drug users (IDUs) at a needle exchange program in Fresno, California. Respondents reported significant decreases in high risk IDU behaviors, including sharing of needles and to a lesser extent re-using of needles. They also reported frequent use of clean paraphernalia. Greater collaboration between social and health outreach professionals at NEPs could provide important frontline assistance to people excluded from mainstream office-based services and enhance efforts to reduce HIV/AIDS or HCV infection.

The influence of flooring on environmental stressors: a study of three flooring materials in a hospital.

OBJECTIVE: Three flooring materials, terrazzo, rubber, and carpet tile, in patient unit corridors were compared for absorption of sound, comfort, light reflectance, employee perceptions and preferences, and patient satisfaction. BACKGROUND: Environmental stressors, such as noise and ergonomic factors, effect healthcare workers and patients, contributing to increased fatigue, anxiety and stress, decreased productivity, and patient safety and satisfaction. METHODS: A longitudinal comparative cohort study comparing three types of flooring assessed sound levels, healthcare worker responses, and patient Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) ratings over 42 weeks. A linear mixed model analysis was conducted to determine significant differences between the means for participant responses and objective sound meter data during all three phases of the study. RESULTS: A significant difference was found for sound levels between flooring type for equivalent continuous sound levels. Carpet tile performed better for sound attenuation by absorption, reducing sound levels 3.14 dBA. Preferences for flooring materials changed over the course of the study. The HCAHPS ratings aligned with the sound meter data showing that patients perceived the noise levels to be lower with carpet tiles, improving patient satisfaction ratings. CONCLUSIONS: Perceptions for healthcare staff and patients were aligned with the sound meter data. Carpet tile provides sound absorption that affects sound levels and influences occupant's perceptions of environmental factors that contribute to the quality of the indoor environment. Flooring that provides comfort underfoot, easy cleanability, and sound absorption influence healthcare worker job satisfaction and patient satisfaction with their patient experience.

Evidence-based interventions for cancer treatment-related mucositis: putting evidence into practice.

Mucositis is an inflammatory process that can involve the mucosal epithelial cells from the mouth to the rectum. Historically, mucositis and stomatitis were used interchangeably, but momentum has increased toward more specific terminology since the 2000s. Stomatitis refers to inflammatory diseases of the mouth, including the mucosa, dentition, periapices, and periodontium, whereas mucositis refers more globally to an inflammatory process involving the mucous membranes of the oral cavity and the gastrointestinal tract. In addition, differentiation is needed regarding mucositis involving the oral cavity and the remainder of the gastrointestinal tract that require use of a scope-type device for close examination. As a result, oral cavity mucositis has been the focus of the majority of the studies reported to date. The mucous membranes beyond the oral cavity are more challenging to view, so the mouth has been presented as revealing potential changes in the gastrointestinal tract. However, because of the variation in morphology, function of different locations, and risks associated with procedures to validate that speculation, evidence is limited. The purpose of this article is to review evidence-based interventions for mucositis, particularly in the oral cavity, and provide clinicians with guidelines for nursing interventions.

Academic and nursing aptitude and the NCLEX-RN in baccalaureate programs.

Accurately predicting NCLEX-RN® success has a positive impact on all nursing education stakeholders. This study focused on the ability to predict NCLEX-RN pass rates on the basis of prenursing academic aptitude variables and the Assessment Technologies Institute (ATI) nursing aptitude program. The ATI predictors were the Test of Essential Academic Skills (TEAS) and fi ve ATI subject tests: Fundamentals, Medical Surgical, Nursing Care of Children, Mental Health, and Maternal Newborn. The prenursing variables comprised the prenursing grade point average, a prerequisite communication course, and the ATI TEAS composite subscores of TEAS Reading, TEAS Math, TEAS Science, and TEAS English. This study included participants from four baccalaureate nursing programs in the California State University system. Results of canonical correlation, multiple linear regression, and logistic regression revealed a significant correlation among prenursing, ATI scores, and NCLEXRN fi rst-try pass rates. Prediction of NCLEX-RN success rate using standardized testing data was supported, with the strongest predictors being the ATI Medical Surgical and ATI Mental Health tests.

The role of flooring as a design element affecting patient and healthcare worker safety.

OBJECTIVE: The objective of this study was to review, identify, and synthesize the literature on patient and healthcare worker safety related to flooring. The topic of flooring in the design of healthcare facilities is complex: healthcare associated infections, push/pull limitations, falls and fall injuries, and noise as a contributing factor to quality of care. BACKGROUND: Most hospitals have not been explicitly designed to enhance patient safety. Recommendations from the Agency for Healthcare Research and Quality (AHRQ) include preventing patient falls, reducing infections, and preventing medication errors as the areas of emphasis of evidence-based design to improve patient safety and quality of care. METHODS: A review of the literature was conducted through search engines using a predefined list of keywords to identify studies about flooring and the safety of patients and healthcare workers. Inclusion criteria included peer-reviewed theoretical and empirical studies published in English from 1982 to 2012. Final inclusion was obtained based on an analysis of research design. RESULTS: Of those 27 articles that met inclusion, 7 focused on healthcare associated infections; 9 focused on slips, trips and falls; 7 articles focused on noise; and 4 focused on fatigue. The studies are profiled in tables and organized by environmental variable. CONCLUSIONS: Though a limited number of studies met the criteria for this review, the evidence base is emerging to design for safety. Recommendations for future research and practical application of design are provided. KEYWORDS: Evidence-based design, literature review, patients, safety, staff.

Assessment of a service provider self-study method to promote interorganizational and community collaboration.

With an emphasis by both public and private funding sources on community-level service integration, many social service organizations have been required to shift from traditional "silo" models of service delivery to increased community-based collaboration and service coordination. There is a paucity of research to identify successful methods to achieve these goals. This article describes a self-study method used to engage service providers in a community development effort designed to meet the needs identified by local residents within their community and empower a rural, unincorporated community with scarce resources. It also reports qualitative outcomes that assessed the utility of a self-study method to achieve collaboration and community empowerment. Communication, ownership, input, and investment among providers appear to be key components to achieving long-term sustainability and success. Implications for the utility of the self-study method for achieving community service integration that aligns with basic principles of community development are discussed.

Accelerated healing of cutaneous leishmaniasis in non-healing BALB/c mice using water soluble amphotericin B-polymethacrylic acid.

Cutaneous leishmaniasis (CL) is a neglected tropical disease that causes prominent skin scaring. No water soluble, non-toxic, short course and low cost treatment exists. We developed a new water soluble amphotericin B-polymethacrylic acid (AmB-PMA) using established and scalable chemistries. AmB-PMA was stable for 9 months during storage. In vitro, it was effective against Leishmania spp. promastigotes and amastigote infected macrophages. It was also less toxic and more effective than deoxycholate-AmB, and similar to liposomal AmB. Its in vivo activity was determined in both early and established CL lesion models of Leishmania major infection in genetically susceptible non-healing BALB/c mice. Intradermal AmB-PMA at a total dose of 18 mg of AmB/kg body weight led to rapid parasite killing and lesion healing. No toxicity was seen. No parasite relapse occurred after 80 days follow-up. Histological studies confirmed rapid parasite clearance from macrophages followed by accelerated fibroblast mediated tissue repair, regeneration and cure of the infection. Quantitative mRNA studies of the CL lesions showed that accelerated healing was associated with increased Tumour Necrosis Factor-α and Interferon-γ, and reduced Interleukin-10. These results suggest that a cost-effective AmB-PMA could be used to pharmacologically treat and immuno-therapeutically accelerate the healing of CL lesions.

Cocaethylene formation following ethanol and cocaine administration by different routes.

Ethanol alters the hepatic biotransformation of cocaine, resulting in transesterification to a novel active metabolite, cocaethylene. Because of first pass metabolism, oral drug administration might be expected to produce relatively larger concentrations of cocaethylene than would intravenous or smoked administration. We, therefore, compared the effects of route of cocaine administration on the formation and elimination of cocaethylene. Six experienced cocaine users were tested in 6 sessions, approximately 1 week apart. Deuterium-labeled cocaine (d5) was administered in all conditions. Oral cocaine-d5 2.0 mg/kg, intravenous cocaine-d5 1.0 mg/kg, and smoked cocaine-d5 (200 mg) were administered after oral ethanol 1.0 g/kg or placebo. A small, intravenous dose of deuterated cocaethylene (d3) also was administered with all conditions for determination of cocaethylene formation. Physiologic and subjective effects were recorded and plasma cocaine-d5, cocaethylene-d5, cocaethylene-d3, and benzoylecgonine-d5 were measured by gas chromatography-mass spectrometry. About 24% (± 11) of intravenous cocaine was converted to cocaethylene. The oral route (34% ± 20) was significantly greater than from the smoked route (18% ± 11) and showed a trend toward significance for greater formation of cocaethylene compared to the intravenous route. Within each route, the cocaine-ethanol combination produced greater increases in heart rate and rate-pressure product than cocaine alone. Global intoxication effects across time after smoking or intravenous administration were significantly greater when cocaine and ethanol were both given. Administration of cocaine by different routes alters the amount of cocaethylene formed through hepatic first-pass effects. Increased cardiovascular and subjective effects might explain the toxicity and popularity of the combined drugs.

The resurgence of granulocyte transfusions.

Granulocyte transfusion can be used as supportive therapy in patients with life-threatening neutropenia caused by bone marrow failure or in patients with neutrophil dysfunction. Emerging evidence demonstrates the benefits of granulocyte transfusions to treat infections in patients after treatment with high-dose chemotherapy, particularly the chemotherapy associated with conditioning for hematopoietic stem cell transplant. There has been an increased interest in the use of therapeutic granulocyte transfusion in recent years due to the ability to use granulocyte colony-stimulated factors to produce higher doses of granulocytes for transfusion. Other factors that influence the outcome of transfusion include the type of infection being treated, the likelihood of recipient marrow recovery, and recipient alloimmunization. This article provides a historical perspective on granulocyte transfusion and an overview of its clinical use.
