COVID-19 Solutions Are Climate Solutions: Lessons From Reusable Gowns.

The COVID-19 pandemic has laid bare the inadequacy of the U.S. healthcare system to deliver timely and resilient care. According to the American Hospital Association, the pandemic has created a $202 billion loss across the healthcare industry, forcing health care systems to lay off workers and making hospitals scramble to minimize supply chain costs. However, as the demand for personal protective equipment (PPE) grows, hospitals have sacrificed sustainable solutions for disposable options that, although convenient, will exacerbate supply strains, financial burden, and waste. We advocate for reusable gowns as a means to lower health care costs, address climate change, and improve resilience while preserving the safety of health care workers. Reusable gowns' polyester material provides comparable capacity to reduce microbial cross-transmission and liquid penetration. In addition, previous hospitals have reported a 50% cost reduction in gown expenditures after adopting reusable gowns; given the current 2000% price increase in isolation gowns during COVID-19, reusable gown use will build both healthcare resilience and security from price fluctuations. Finally, with the United States' medical waste stream worsening, reusable isolation gowns show promising reductions in energy and water use, solid waste, and carbon footprint. The gowns are shown to withstand laundering 75-100 times in contrast to the single-use disposable gown. The circumstances of the pandemic forewarn the need to shift our single-use PPE practices to standardized reusable applications. Ultimately, sustainable forms of protective equipment can help us prepare for future crises that challenge the resilience of the healthcare system.

Impact of Education on Knowledge and Practice of Kala Azar Preventive Measures among Seasonal and Migrant Agricultural Workers in Northwest Ethiopia.

Kala azar occurs among seasonal and migrant agricultural workers in northwest Ethiopia and accounts for almost 60% of the disease burden in the country. We conducted a quantitative study on the level of knowledge and practice of this vulnerable group in relation to kala azar transmission and acceptability of its vector control tools. A total of 403 workers were randomly selected from eight farms using a purposive sampling technique. Knowledge and practice scores were calculated based on 12 and 9 core questions, respectively. Binary logistic regression was used to identify factors associated with knowledge and practice. A large gap in knowledge of the disease and the vector was evident with 61.8%, 24.6%, and 13.6% of the workers having poor, moderate, and good levels of knowledge scores, respectively. Similarly, 95% of the seasonal workers reported poor level of use of protective measures against the bite of the sand fly vector. Good level of knowledge about kala azar and its sand fly vector was statistically associated with formal education (adjusted odds ratio [AOR] = 2.11; 95% CI = 1.17, 3.80; P < 0.05) and previous exposure to health education (AOR = 4.72; 95% CI = 1.99, 11.16; P < 0.001). Despite poor current knowledge and practice, a large proportion of the study participants showed interest in using vector control tools if made available, with 78% of the seasonal and migrant workers expressing some willingness to pay for different measures that can protect against sand fly bites. Therefore, we strongly recommend that comprehensive health education and vector control programs should be provided to these workers.

Surgeon Personal Protection: An Underappreciated Benefit of Positive-pressure Exhaust Suits.

BACKGROUND: Positive-pressure exhaust suits cost more than standard surgical gowns, and recent evidence suggests that they do not decrease infection risk. As a result, some hospitals and surgeons have abandoned positive-pressure exhaust suits in favor of less expensive alternatives. We propose that in addition to their original purpose of decreasing infection rates, positive-pressure exhaust suits may also improve personal protection for the surgeon and assistants, perhaps justifying their added costs. QUESTIONS/PURPOSES: (1) Do positive-pressure exhaust suits decrease exposure to particulate matter during TKA? (2) What areas covered by gowning systems are at risk of exposure to particulate matter? METHODS: Three surgical gowning systems were tested: (1) surgical gown, face mask, surgical skull cap, protective eyewear; (2) surgical gown, face mask, surgical protective hood, protective eyewear; and (3) positive-pressure exhaust suit. For each procedure, a cadaver knee was injected intraarticularly and intraosseously with a 5-µm fluorescent powder mixed with water (1 g/10 mL). After gowning in the standard sterile fashion, the primary surgeon and two assistants performed two TKAs with each gowning system for a total of six TKAs. After each procedure, three independent observers graded skin exposure of each surgical participant under ultraviolet light using a standardized scale from 0 (no exposure) to 4 (gross exposure). Statistical analysis was performed using Friedman's and Nemenyi tests. The interrater reliability for the independent observers was also calculated. RESULTS: The positive-pressure exhaust suits had less surgeon and assistant exposure compared with other systems (p < 0.001). The median overall exposure grade for each gowning system was 4 for System 1 (range, 3-4), 2.5 for System 2 (range, 2-3), and 0 for System 3 (range, 0-0). In pairwise comparisons between gowning systems, the positive-pressure exhaust suits had less exposure than gowning System 1 (difference of medians: 4, p < 0.001) and gowning System 2 (difference of medians: 2.5, p = 0.038). There was no difference found in exposure between Systems 1 and 2 (difference of medians: 1.5, p = 0.330). When gowning Systems 1 and 2 were removed, particulate matter was found in places that were covered such as the surgeon's beard, lips, inside the nostrils, behind the protective eyewear around the surgeon's eye, and in both eyebrows and eyelashes. CONCLUSIONS: The positive-pressure exhaust suits provided greater personal protection with each procedure than the other two gowning systems. CLINICAL RELEVANCE: With conventional gowns, particulate matter was found in the surgeon's eyelashes, under the face mask around the mouth, and inside the nostrils. Despite recent evidence that certain types of positive-pressure exhaust suits may not decrease infection, there is a clear benefit of surgeon protection from potentially infectious and harmful patient substances. Despite their added costs, hospitals and surgeons should weigh this protective benefit when considering the use of positive-pressure exhaust suits.

An Assessment of Household and Individual-Level Mosquito Prevention Methods during the Chikungunya Virus Outbreak in the United States Virgin Islands, 2014-2015.

Recent large-scale chikungunya virus (CHIKV) and Zika virus epidemics in the Americas pose a growing public health threat. Given that mosquito bite prevention and vector control are the main prevention methods available to reduce transmission of these viruses, we assessed adherence to these methods in the United States Virgin Islands (USVI). We interviewed 334 USVI residents between December 2014 and February 2015 to measure differences in mosquito prevention practices by gender, income, presence of CHIKV symptoms, and age. Only 27% (91/334) of participants reported having an air conditioner, and of the 91 with air-conditioners, 18 (20%) reported never using it. Annual household income > $50,000 was associated with owning and using an air conditioner (41%; 95% confidence interval [CI]: 28-53% compared with annual household income ≤ $50,000: 17%; 95% CI: 12-22%). The majority of participants reported the presence of vegetation in their yard or near their home (79%; 265) and a cistern on their property (78%; 259). Only 52 (16%) participants reported wearing mosquito repellent more than once per week. Although the majority (80%; 268) of participants reported having screens on all of their windows and doors, most (82%; 273) of those interviewed still reported seeing mosquitoes in their homes. Given the uniformly low adherence to individual- and household-level mosquito bite prevention measures in the USVI, these findings emphasize the need for improved public health messaging and investment in therapeutic and vaccine research to mitigate vector-borne disease outbreaks.

Profiles of law enforcement agency body armor policies-A latent class analysis of the LEMAS 2013 data.

The life-saving benefits of body armor have been well-documented, and law enforcement agency (LEA) body armor wear requirements have been cited by police officers as one of the most important reasons for them to wear body armor. However, research on LEAs' policies and practices regarding body armor is scarce. This study examined whether there are different agency-level profiles of various body armor-related policies, and related these body armor policy profiles to agency characteristics, size, location, etc. U.S. LEAs fell into four distinct profiles based on their body armor policies. Close to half of the LEAs had comprehensive coverage of body armor policies in all aspects. However, nearly one in five LEAs had very weak body armor policies in all aspects. The rest of the LEAs split into two groups, each with different strengths and weaknesses on selection, training, fitting, wearing, and inspection policies. Sheriff's offices and smaller LEAs were found to have weaker policies. In contrast, LEAs with a community policing emphasis and those with body armor grants were found to have stronger body armor polices, especially when it comes to mandatory wearing polices. Findings from the study provide a portrait of the current state of LEA body armor policies, and provide guidance for improving LEAs' body armor policies and practices.

Elimination of Routine Contact Precautions for Endemic Methicillin-Resistant Staphylococcus aureus and Vancomycin-Resistant Enterococcus: A Retrospective Quasi-Experimental Study.

OBJECTIVE To evaluate the impact of discontinuation of contact precautions (CP) for methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE) and expansion of chlorhexidine gluconate (CHG) use on the health system. DESIGN Retrospective, nonrandomized, observational, quasi-experimental study. SETTING Two California hospitals. PARTICIPANTS Inpatients. METHODS We compared hospital-wide laboratory-identified clinical culture rates (as a marker of healthcare-associated infections) 1 year before and after routine CP for endemic MRSA and VRE were discontinued and CHG bathing was expanded to all units. Culture data from patients and cost data on material utilization were collected. Nursing time spent donning personal protective equipment was assessed and quantified using time-driven activity-based costing. RESULTS Average positive culture rates before and after discontinuing CP were 0.40 and 0.32 cultures/100 admissions for MRSA (P=.09), and 0.48 and 0.40 cultures/100 admissions for VRE (P=.14). When combining isolation gown and CHG costs, the health system saved $643,776 in 1 year. Before the change, 28.5% intensive care unit and 19% medicine/surgery beds were on CP for MRSA/VRE. On the basis of average room entries and donning time, estimated nursing time spent donning personal protective equipment for MRSA/VRE before the change was 45,277 hours/year (estimated cost, $4.6 million). CONCLUSION Discontinuing routine CP for endemic MRSA and VRE did not result in increased rates of MRSA or VRE after 1 year. With cost savings on materials, decreased healthcare worker time, and no concomitant increase in possible infections, elimination of routine CP may add substantial value to inpatient care delivery.

Parafricta Bootees and Undergarments to Reduce Skin Breakdown in People with or at Risk of Pressure Ulcers: A NICE Medical Technologies Guidance.

As part of the development of the National Institute for Health and Care Excellence (NICE) Medical Technologies Guidance on Parafricta Bootees and Undergarments to reduce skin breakdown in people with, or at risk of, pressure ulcers, the manufacturer (APA Parafricta Ltd) submitted clinical and economic evidence, which was critically appraised by an External Assessment Centre (EAC) and subsequently used by the Medical Technologies Advisory Committee (MTAC) to develop recommendations for further research. The University of Birmingham and Brunel University, acting as a consortium, were commissioned to act as the EAC, independently appraising the submission. This article is an overview of the original evidence submitted, the EAC's findings and the final NICE guidance. Very little comparative evidence was submitted to demonstrate the effectiveness of Parafricta Bootees or Undergarments. The sponsor submitted a simple cost analysis to estimate the costs of using Parafricta in addition to current practice-in comparison with current practice alone-in hospital and community settings separately. The analysis took a National Health Service (NHS) perspective. The basis of the analysis was a previously published comparative study, which showed no statistical difference in average lengths of stay between patients who wore Parafricta Undergarments and Bootees, and those who did not. The economic model incorporated the costs of Parafricta but assumed shorter lengths of stay with Parafricta. The sponsor concluded that Parafricta was cost saving relative to the comparators. The EAC made amendments to the sponsor's analysis to correct for errors and to reflect alternative assumptions. Parafricta remained cost saving in most analyses, and the savings per prevalent case ranged from £757 in the hospital model to £3455 in the community model. All analyses were severely limited by the available data on effectiveness-in particular, a lack of good-quality comparative studies.

Barriers and Facilitators to Scaling Up the Non-Pneumatic Anti-Shock Garment for Treating Obstetric Hemorrhage: A Qualitative Study.

BACKGROUND: Obstetric hemorrhage (OH), which includes hemorrhage from multiple etiologies during pregnancy, childbirth, or postpartum, is the leading cause of maternal mortality and accounts for one-quarter of global maternal deaths. The Non-pneumatic Anti-Shock Garment (NASG) is a first-aid device for obstetric hemorrhage that can be applied for post-partum/post miscarriage and for ectopic pregnancies to buy time for a woman to reach a health care facility for definitive treatment. Despite successful field trials, and endorsement by safe motherhood organizations and the World Health Organization (WHO), scale-up has been slow in some countries. This qualitative study explores contextual factors affecting uptake. METHODS: From March 2013 to April 2013, we conducted 13 key informant interviews across four countries with a large burden of maternal mortality that had achieved varying success in scaling up the NASG: Ethiopia, India, Nigeria, and Zimbabwe. These key informants were health providers or program specialists working with the NASG. We applied a health policy analysis framework to organize the results. The framework has five domains: attributes of the intervention, attributes of the implementers, delivery strategy, attributes of the adopting community, the socio-political context, and the research context. RESULTS: The interviews from our study found that relevant facilitators for scale-up are the simplicity of the device, local and international champions, well-developed training sessions, recommendations by WHO and the International Federation of Gynecology and Obstetrics, and dissemination of NASG clinical trial results. Barriers to scaling up the NASG included limited health infrastructure, relatively high upfront cost of the NASG, initial resistance by providers and policy makers, lack of in-country champions or policy makers advocating for NASG implementation, inadequate return and exchange programs, and lack of political will. CONCLUSIONS: There was a continuum of uptake ranging in both speed and scale. Ethiopia while not the first country to use the NASG has the most rapid scale-up, followed by Nigeria, then India, and finally Zimbabwe. Increasing the coverage of the NASG will require collaboration with local NASG champions, greater NASG awareness among clinicians and policymakers, as well as stronger political will and advocacy.

Burn Center Barrier Protocols During Dressing Change: A National Survey.

Infection control is a critical component of post-burn care with prevention of infection serving as a major cause of decreasing morbidity and mortality. One potential deterrent for infection is barrier protection during dressing changes; however, no evidence-based standard has been established among burn centers. The purpose of this study is to describe the current barrier techniques of American burn centers. A 24-question survey was sent to 121 burn center nurse managers within the United States. The survey was comprised of yes or no questions with comment sections available for further detail. Questions were constructed to gain insight into the variation and commonality that may exist between burn center barrier protocols. Forty-one out of 121 centers (34%) responded. Centers reported the use of head covers, masks, gowns, and gloves during admission of a new burn (71%, 82%, 95%, and 100% respectively); daily dressing changes (64%, 80%, 97%, and 100% respectively); postoperative dressing changes (64%, masks 80%, 97%, and 100% respectively); and dressing changes of a nonburn (66%, 82%, 97%, and 100% respectively). Burn centers reported their use of sterile gloves and gowns during typical burn dressing changes as occurring 20% and 10% of the time, respectively. Estimates for costs of these garments annually ranged from $0 to $250,000. A calculation performed for this study demonstrated that barrier garments used for dressing changes nationwide is approximately $2.43 million. We demonstrated the immense cost, to an institution and nationwide, of barrier garments used solely for dressing changes.

Value of extended warming in patients undergoing elective surgery.

Perioperative temperature management is imperative for positive surgical outcomes. This study assessed the clinical and wellbeing benefits of extending normothermia by using a portable warming gown. A total of 94 patients undergoing elective surgery were enrolled. They were randomized pre-operatively to either a portable warming gown or the standard warming procedure. The warming gown stayed with patients from pre-op to operating room to postrecovery room discharge. Core temperature was tracked throughout the study. Patients also provided responses to a satisfaction and comfort status survey. The change in average core temperature did not differ significantly between groups (P = 0.23). A nonsignificant 48% relative decrease in hypothermic events was observed for the extended warming group (P = 0.12). Patients receiving the warming gown were more likely to report always having their temperature controlled (P = 0.04) and significantly less likely to request additional blankets for comfort (P = 0.006). Clinical outcomes and satisfaction were improved for patients with extended warming.

Use of insecticide-treated school uniforms for prevention of dengue in schoolchildren: a cost-effectiveness analysis.

BACKGROUND: Dengue-related illness is a leading cause of hospitalization and death, particularly among children. Practical, acceptable and affordable measures are urgently needed to protect this age group. Schools where children spend most of their day is proposed as an ideal setting to implement preventive strategies against day-biting Aedes mosquitoes. The use of insecticide-treated school uniforms is a promising strategy currently under investigation. METHODS: Using a decision-analytic model, we evaluated the cost-effectiveness of the use of insecticide-treated school uniforms for prevention of dengue, compared with a "do-nothing" alternative, in schoolchildren from the societal perspective. We explored how the potential economic value of the intervention varied under various scenarios of intervention effectiveness and cost, as well as dengue infection risk in school-aged children, using data specific to Thailand. RESULTS: At an average dengue incidence rate of 5.8% per year in school-aged children, the intervention was cost-effective (ICER≤$16,440) in a variety of scenarios when the intervention cost per child was $5.3 or less and the intervention effectiveness was 50% or higher. In fact, the intervention was cost saving (ICER<0) in all scenarios in which the intervention cost per child was $2.9 or less per year and the intervention effectiveness was 50% or higher. The results suggested that this intervention would be of no interest to Thai policy makers when the intervention cost per child was $10.6 or higher per year regardless of intervention effectiveness (ICER>$16,440). CONCLUSIONS: Our results present the potential economic value of the use of insecticide-treated uniforms for prevention of dengue in schoolchildren in a typical dengue endemic setting and highlight the urgent need for additional research on this intervention.

[Cost analysis comparing single-use (Ambu® aScope™) and conventional reusable fiberoptic flexible scopes for difficult tracheal intubation]. / Analyse de coût comparant les fibroscopes à usage unique (Ambu®aScope™) et les fibroscopes réutilisables pour l'intubation difficile.

OBJECTIVE: Recommendations on difficult tracheal intubation constrain each surgical block to have a fiberscope available. Reusable fiberscope presents the problem of availability, the risk of non-conventional infections transmission and the cost. Single-use fiberscopes are presently available (Ambu® aScope™). This medico-economic study aims to assess the cost of using a reusable fiberscope as compared to the single use fiberscope. STUDY DESIGN: Cost minimization analysis. MATERIAL: Reusable fiberscope Pentax® FB 15P (Pentax France, Argenteuil) and single-use fiberscope Ambu® aScope™ (Ambu A/S, Ballerup, Denmark). METHOD: Minimization-cost analysis conducted between 2006 and 2012. The amortization cost per utilization for two reusable fiberscopes took into account the acquisition and maintenance costs, as well as the costs related to disinfection. The cost of the single use fiberscope was calculated according to its acquisition cost. RESULTS: The total cost of the reusable material was 55,874€ over 6years, corresponding to a unitary cost of 206€ per fiberscopy. During this period, 780 sterilizations were carried out for a total cost of 32,611€. Acquisition and maintenance costs were respectively 18,382€ and 4880€. The cost of the single use fiberscope is of 200€ per fiberscopy. CONCLUSION: This medico-economic evaluation shows that the utilization cost of single use and reusable fiberscopes are very close. This should be analyzed at the light of some benefits of using single use devices for the difficult tracheal intubation.
