Multimodal Assessment and Intramodal Comparison of Imaging Techniques for Pediatric Pulmonary Vein Stenosis with Pulmonary Hypertension.

Pulmonary vein stenosis (PVS) is a rare, serious, and progressive disease in the pediatric population. Evaluation is complex and involves multimodality imaging. Diagnosis is important as early treatment to prevent progressive pulmonary hypertension and right ventricular dysfunction is essential. Adult studies have shown good correlation between various imaging modalities; however, there are limited data in children. This is a single-center retrospective pilot study to determine the reliability of measurement of pulmonary vein stenosis and pulmonary hypertension across different imaging modalities-computed tomography angiography (CTA), echocardiography (echo), lung perfusion scan (LPS), and cardiac catheterization (cath). PVS was defined as > 2 mmHg by echo and cath and/or 50% reduction in diameter by CTA. Patients had to have an echo, CTA and cath performed within a 1-month timeframe of one another to be included in the study, with LPS data included if testing was completed at initial evaluation. Fifteen total patients were enrolled; 87% were categorized as primary PVS; a condition not directly related to direct injury or prior surgical intervention. Twenty-seven total stenotic pulmonary veins were identified (mean 1.8, range 1-4). CTA had a slightly better agreement with cath than echo in identifying PVS in different vein locations except in the LLPV. Additionally, echo and CTA had excellent sensitivity (91%) and specificity (100%) compared to cath for diagnosis of PH. We conclude that non-invasive imaging of echo and CTA has an acceptable correlation to cardiac catheterization for screening and initial evaluation of PVS and PH, as directly related to PVS, in pediatrics.

Walking together in friendship: Learning about cultural safety in mainstream mental health services through Aboriginal Participatory Action Research.

OBJECTIVE: Culturally safe service provision is essential to improving social and emotional wellbeing among Aboriginal and Torres Strait Islander communities, and to eliminating health inequities. Cultural safety is about ensuring that all people have a safe and healing journey through services, regardless of their cultural background. In this project, we aim to (1) understand how Aboriginal and Torres Strait Islander peoples conceptualise cultural safety, and (2) co-design a qualitative interview for the next phase of this project, where we plan to learn about experiences of cultural safety within mental health services. METHODS: We conducted six focus groups (in one metro and two regional areas, Western Australia). Following an Aboriginal Participatory Action Research methodology, we yarned with Aboriginal and Torres Strait Islander mental health service users, carers, community members, mental health professionals and Cultural Healers about cultural safety. RESULTS: Participants described a culturally safe service as one where Aboriginal cultural knowledges, life experiences, issues and protocols are understood and acknowledged, and reported that mainstream mental health services are not currently culturally safe. Participants emphasised the importance of building trust, rapport, reciprocity and following appropriate relational processes when designing a qualitative interview for the next phase. CONCLUSIONS: A lack of cultural safety in mental health services is likely to contribute to the disparity in outcomes between Aboriginal and Torres Strait Islander peoples and non-Indigenous Australians. Embedding cultural safety into research design allows for authentic community engagement and facilitates knowledge sharing around ways to improve cultural safety in mental health services.

Evaluating a social and emotional well-being model of service piloted in Aboriginal Community Controlled Health Services in Western Australia: an Aboriginal Participatory Action Research approach.

INTRODUCTION: The delivery of services to improve Aboriginal health and well-being must centre culture and integrate a social and emotional well-being understanding and approaches. These approaches are essential in increasing access to, and engagement with, health services, as well as ensuring culturally safe, person-centred and community-centred care. This study will evaluate the Aboriginal Health Council of Western Australia's social and emotional well-being model of service being piloted in five Aboriginal Community Controlled Health Services across five of Western Australia's regions. The model of service includes the establishment of interdisciplinary social and emotional well-being teams and a four-pillar approach to service delivery. METHODS AND ANALYSIS: An Aboriginal Participatory Action Research methodology will be undertaken which calls for Indigenous leadership and governance, capacity-building of community co-researchers and engagement in reflexive practice. The evaluation will take a mixed-methods approach to data collection, including at each pilot site, yarns with up to five clients engaging with social and emotional well-being services; qualitative interviews with up to five service providers at each site, and up to five key knowledge holders from stakeholders including funders and commissioning bodies; the collection of clinical data; facilitated discussion using the social and emotional well-being Systems Assessment Tool; and document analysis and cost-estimation. Analysis will be guided by a client journey mapping framework, and data will be collectively analysed through a socioecological framework to understand the connections and inter-relatedness between client outcomes and experiences, social and emotional well-being team and service provider experiences, service systems and governance structures. ETHICS AND DISSEMINATION: This evaluation was approved by the Western Australian Aboriginal Health Ethics Committee (HREC1204). The findings will be disseminated through the production of an evaluation report and academic publications and presentations. Findings will also be disseminated through community forums and plain language summaries. These outputs will detail evaluation findings and recommendations, the process of evaluation through an Aboriginal Participatory Action Research approach and the collaborative stakeholder relationship-building that underpinned the project.

Co-designing research with Aboriginal and Torres Strait Islander consumers of mental health services, mental health workers, elders and cultural healers.

INTRODUCTION: The disparity in mental health outcomes compared with non-Indigenous Australians means that there is an urgent need to develop an evidence base around how services can better support Aboriginal and Torres Strait Islander communities. A critical first step is to embed cultural safety into research methodologies. OBJECTIVE: Here, we aim to establish the foundation of a research project through co-designing a qualitative interview with Aboriginal and Torres Strait Islander consumers and community members about experiences of cultural safety with mainstream mental health services. DESIGN: Voices of Aboriginal and Torres Strait Islander peoples must be empowered across all stages of research. An Aboriginal-led research team conducted focus groups to understand clear, sensitive, and culturally appropriate ways of asking about experiences in mental health care, to co-design an interview on this topic. Participants were Aboriginal and Torres Strait Islander consumers of mental health services, carers, mental health workers, Elders and Cultural Healers, living in Metropolitan and Regional Western Australia. FINDINGS: Results suggest that Indigenous governance, together with investing in ongoing, and meaningful cultural awareness and cultural safety training (cultural awareness being a first step towards safety) for non-Indigenous researchers, together with taking the time to build respectful partnerships with communities through ongoing consultation, were appropriate and comprehensive methods of co-designing an interview. DISCUSSION: The process of working with Aboriginal and Torres Strait Islander peoples in research is as important as the outcome. Aboriginal and Torres Strait Islander leadership, self-determination, and relationship building with communities are essential. CONCLUSION: Empowering co-design methodologies are flexible, iterative, and ensure that the experiences and views of participants are valued, leading to more meaningful results.

Economical defence of resources structures territorial space use in a cooperative carnivore.

Ecologists have long sought to understand space use and mechanisms underlying patterns observed in nature. We developed an optimality landscape and mechanistic territory model to understand mechanisms driving space use and compared model predictions to empirical reality. We demonstrate our approach using grey wolves (Canis lupus). In the model, simulated animals selected territories to economically acquire resources by selecting patches with greatest value, accounting for benefits, costs and trade-offs of defending and using space on the optimality landscape. Our approach successfully predicted and explained first- and second-order space use of wolves, including the population's distribution, territories of individual packs, and influences of prey density, competitor density, human-caused mortality risk and seasonality. It accomplished this using simple behavioural rules and limited data to inform the optimality landscape. Results contribute evidence that economical territory selection is a mechanistic bridge between space use and animal distribution on the landscape. This approach and resulting gains in knowledge enable predicting effects of a wide range of environmental conditions, contributing to both basic ecological understanding of natural systems and conservation. We expect this approach will demonstrate applicability across diverse habitats and species, and that its foundation can help continue to advance understanding of spatial behaviour.

Tract metastasis in patients with long-term pleural catheter-computed tomography diagnosis and longitudinal assessment.

OBJECTIVES: Long-term indwelling pleural catheters (IPC), used for the management of malignant pleural mesothelioma (MPM), may lead to catheter tract metastasis (CTM). While computed tomography (CT) is valuable for diagnosis, no studies have assessed CT manifestations of CTM. Our goal is to describe the incidence, CT appearances, and temporal evolution of CTM in MPM. METHODS: A retrospective review of CT of 90 consecutive patients with MPM and IPC. In patients with CTM, a longitudinal assessment was performed for CT appearance at diagnosis and over time, interval from insertion to diagnosis and rate of progression. RESULTS: The incidence of CTM was 26% (23/90), in 22 men (54-83 years, mean 73 years). CTM manifested with focal lesion (3 to 60 mm, mean 25 mm) in the subcutaneous tissue at the insertion site. Abnormalities of sub-adjacent skin and fat stranding were present in 16/24 (66%) and 11/24 (46%), respectively, enlargement of chest wall musculature in 11/24 (46%), and dilated subcutaneous vessels in 4/24 (17%) patients. On follow-up, 53% had enlargement of focal lesion. The average rate of progression was 3.5 mm/month, compared to 0.79 mm/month for pleural thickening (p = 0.03). The time between IPC insertion and CTM diagnosis varied from 58 to 1375 days (median 408 days); 83% occurred after IPC removal. Reporting radiologists described focal abnormality at the insertion site in only 9/23 (39%) patients. CONCLUSIONS: CTM is commonly overlooked and underreported by radiologists. CT invariably demonstrates focal subcutaneous lesion in the procedure tract, most commonly after IPC removal. Ancillary findings, notably serratus or latissimus dorsi muscle enlargement, are novel finding that can assist in CT detection and diagnosis. KEY POINTS: • Catheter tract metastasis (CTM), resulting from indwelling pleural catheter to manage malignant pleural mesothelioma, invariably manifested on CT as a focal subcutaneous lesion at the site of insertion, more commonly after catheter removal. • Ipsilateral muscle enlargement is a newly described CT finding that can assist in the detection and diagnosis. • Catheter tract metastasis was commonly overlooked by radiologists, reported in only 39% of cases.

Evidence of economical territory selection in a cooperative carnivore.

As an outcome of natural selection, animals are probably adapted to select territories economically by maximizing benefits and minimizing costs of territory ownership. Theory and empirical precedent indicate that a primary benefit of many territories is exclusive access to food resources, and primary costs of defending and using space are associated with competition, travel and mortality risk. A recently developed mechanistic model for economical territory selection provided numerous empirically testable predictions. We tested these predictions using location data from grey wolves (Canis lupus) in Montana, USA. As predicted, territories were smaller in areas with greater densities of prey, competitors and low-use roads, and for groups of greater size. Territory size increased before decreasing curvilinearly with greater terrain ruggedness and harvest mortalities. Our study provides evidence for the economical selection of territories as a causal mechanism underlying ecological patterns observed in a cooperative carnivore. Results demonstrate how a wide range of environmental and social conditions will influence economical behaviour and resulting space use. We expect similar responses would be observed in numerous territorial species. A mechanistic approach enables understanding how and why animals select particular territories. This knowledge can be used to enhance conservation efforts and more successfully predict effects of conservation actions.

The Children's Data Network: Harnessing the scientific potential of linked administrative data to inform children's programs and policies.

The Children's Data Network (CDN) is a data and research collaborative focused on the linkage and analysis of administrative records. In partnership with public agencies, philanthropic funders, affiliated researchers, and community stakeholders, we seek to generate knowledge and advance evidence-rich policies that improve the health, safety, and well-being of the children of California. Given our experience negotiating access to and working with existing administrative data (and importantly, data stewards), the CDN has demonstrated its ability to perform cost-effective and rigorous record linkage, answer time-sensitive policy- and program-related questions, and build the public sector's capacity to do the same. Owing to steadfast and generous infrastructure and project support, close collaboration with public partners, and strategic analyses and engagements, the CDN has promoted a person-level and longitudinal understanding of children and families in California and in so doing, informed policy and program development nationwide. We sincerely hope that our experience-and lessons learned-can advance and inform work in other fields and jurisdictions.

Early Readmission to Hospital in Patients With Cancer With Malignant Pleural Effusions: Analysis of the Nationwide Readmissions Database.

BACKGROUND: Hospital readmissions are costly to health-care systems and represent a measure of quality care. Patients with cancer with malignant pleural effusions (MPEs) are at high risk for rehospitalization; however, risk factors for readmissions in this population are not well described. Understanding the incidence and risk factors for readmission could facilitate the development of a readmission reduction strategy in this patient population. METHODS: We conducted a retrospective cohort study using the Nationwide Readmissions Database (NRD) (2014 sample) to determine the proportion of all-cause, unplanned, 30-day readmissions to hospital among patients with MPEs. Survey weighting methods that accounted for the NRD sampling design were used to generate nationally representative estimates. We used multivariable logistic regression to determine predictors of early readmission. RESULTS: There were 27,900 unplanned readmissions after 108,824 index hospitalizations for MPEs, a rate of 25.6% (95% CI, 25.0%-26.3%). The mortality rate during readmission to hospital was 17.3% (n = 4,840; 95% CI, 16.6%-18.1%). Mean cost per readmission was $15,452 ± $415, with total aggregate costs of > $400 million. Predictors of early readmission included having Medicaid insurance status, treatment with thoracentesis only, and discharge to a care facility or home health care. CONCLUSIONS: One in four patients with cancer and MPEs are readmitted to hospital within 30 days of discharge, and nearly one in five die during the readmission. Nondefinitive management with thoracentesis led to more readmissions. A further understanding of factors that drive preventable readmissions could significantly improve quality of care in this population.

Expanding Home-Based Primary Care to American Indian Reservations and Other Rural Communities: An Observational Study.

BACKGROUND/OBJECTIVES: Home-based primary care (HBPC) is a comprehensive, interdisciplinary program to meet the medical needs of community-dwelling populations needing long-term care (LTC). The U.S. Department of Veterans Affairs (VA) expanded its HBPC program to underserved rural communities, including American Indian reservations, providing a "natural laboratory" to study change in access to VA LTC benefits and utilization outcomes for rural populations that typically face challenges in accessing LTC medical support. DESIGN: Pretest-Posttest quasi-experimental approach with interrupted time-series design using linked VA, Medicare, and Indian Health Service (IHS) records. SETTING: American Indian reservations and non-Indian communities in rural HBPC catchment areas. PARTICIPANTS: 376 veterans (88 IHS beneficiaries, 288 non-IHS beneficiaries) with a HBPC length of stay of 12 months or longer. MEASUREMENTS: Baseline demographic and health characteristics, activities of daily living (ADL), previous VA enrollment, and hospital admissions and emergency department (ED) visits as a function of time, accounting for IHS beneficiary and functional statuses. RESULTS: For HBPC users, VA enrollment increased by 22%. At baseline, 30% of IHS and non-IHS beneficiaries had 2 or more ADLs impairments; IHS populations were younger (P < .001) and had more diagnosed chronic diseases (P = .007). Overall, hospital admissions decreased by 0.10 (95% confidence interval (CI) = -0.14 to -0.05) and ED visits decreased by 0.13 (95% CI = -0.19 to -0.07) in the 90 days after HBPC admission (Ps < .001) and these decreases were maintained over 1 year follow-up. Before HBPC, probability of hospital admission was 12% lower for IHS than non-IHS beneficiaries (P = .02). CONCLUSION: Introducing HBPC to rural areas increased access to LTC and enrollment for healthcare benefits, with equitable outcomes in IHS and non-IHS populations.

Development and Application of Human Renal Proximal Tubule Epithelial Cells for Assessment of Compound Toxicity.

Kidney toxicity is a major problem both in drug development and clinical settings. It is difficult to predict nephrotoxicity in part because of the lack of appropriate in vitro cell models, limited endpoints, and the observation that the activity of membrane transporters which plays important roles in nephrotoxicity by affecting the pharmacokinetic profile of drugs is often not taken into account. We developed a new cell model using pseudo-immortalized human primary renal proximal tubule epithelial cells. This cell line (SA7K) was characterized by the presence of proximal tubule cell markers as well as several functional properties, including transporter activity and response to a few well-characterized nephrotoxicants. We subsequently evaluated a group of potential nephrotoxic compounds in SA7K cells and compared them to a commonly used human immortalized kidney cell line (HK-2). Cells were treated with test compounds and three endpoints were analyzed, including cell viability, apoptosis and mitochondrial membrane potential. The results showed that most of the known nephrotoxic compounds could be detected in one or more of these endpoints. There were sensitivity differences in response to several of the chemicals between HK-2 and SA7K cells, which may relate to differences in expressions of key transporters or other components of nephrotoxicity pathways. Our data suggest that SA7K cells appear as promising for the early detection of renal toxicants.

Transposition of the great arteries--outcomes and time interval of early neonatal repair.

BACKGROUND: This study evaluates the relationship of morbidity and resource utilization with the timing of early neonatal repair of transposition of the great arteries and intact ventricular septum (d-TGA/IVS). METHODS: All patients with d-TGA/IVS who underwent arterial switch in the first 14 days of life, between January 2000 and May 2011, were reviewed. Patients undergoing repair at ≤ 4 days of age were categorized as group I, 5 to 7 days as group II, and 8 to 14 days as group III. Outcomes included mortality, morbidity, and resource utilization. RESULTS: Hospital survival was 69 (98.6%) of 70. The length of stay (LOS) and total charges were lowest in group I--15.5 days compared to group II--18.0 days and group III--23.5 days (P = .005); group I--US$128,219 compared to group II--US$141,729 and group III--US$217,427 (P = .0006). Using regression analysis to account for potentially confounding effects of multiple variables and treating time as a continuous variable demonstrated that age at surgery was significantly associated with total LOS (P = .029), hospital charges (P = .029) and intensive care unit charges (P = .002). Younger age at repair was not associated with worse outcomes for any measure of morbidity. CONCLUSIONS: Earlier repair of d-TGA/IVS was associated with decreased resource utilization and no detriment to clinical outcomes. Further analysis based on a larger cohort of patients is needed to verify these results that have important implications for improving the value of care.

Community fall prevention programs: comparing three InSTEP models by levels of intensity.

The Fall Prevention Center of Excellence designed three progressive-intensity fall prevention program models, Increasing Stability Through Evaluation and Practice (InSTEP), to reduce risk in community-dwelling older adults. Each model included physical activity, medical risk, and home safety components and was implemented as a 12-week program for small class sizes (12-15 people) in community and senior centers. Change in fall rates and fall risk factors was assessed using a battery of performance tests, self-reports of function, and fall diaries in a 3-group within-subjects (N = 200) design measured at baseline, immediately postintervention, and at 3 and 9 months postintervention. Overall, participants experienced a reduction in falls, improved selfperception of gait and balance, and improved dynamic gait function. The medium-intensity InSTEP model significantly (p = .003) reduced self-reported falls in comparison with the other models. InSTEP is a feasible model for addressing fall risk reduction in community-dwelling older adults.

Guidelines for conducting bulletproof workplace investigations: Part II--searches, surveillance, and other legal issues.

A proper and thorough investigation can help avoid or successfully defend lawsuits. When conducting workplace investigations, employers must take care to conduct reasonable searches and not violate employees' rights to privacy. This article addresses privacy and other legal issues surrounding the use of various types of electronic surveillance including wiretapping, video/photography, and monitoring of e-mail. While conducting such searches, employers must be vigilant in their efforts to avoid liability for defamation and to properly document the investigation. Guidance is provided on these issues along with advice on the recommendation and/or remedial action that may result from the investigation and a checklist of additional considerations when conducting investigations resulting from harassment.

Selective analysis of cell-free DNA in maternal blood for evaluation of fetal trisomy.

OBJECTIVE: To develop a novel prenatal assay based on selective analysis of cell-free DNA in maternal blood for evaluation of fetal Trisomy 21 (T21) and Trisomy 18 (T18). METHODS: Two hundred ninety-eight pregnancies, including 39 T21 and seven T18 confirmed fetal aneuploidies, were analyzed using a novel, highly multiplexed assay, termed digital analysis of selected regions (DANSR™). Cell-free DNA from maternal blood samples was analyzed using DANSR assays for loci on chromosomes 21 and 18. Products from 96 separate patients were pooled and sequenced together. A standard Z-test of chromosomal proportions was used to distinguish aneuploid samples from average-risk pregnancy samples. DANSR aneuploidy discrimination was evaluated at various sequence depths. RESULTS: At the lowest sequencing depth, corresponding to 204,000 sequencing counts per sample, average-risk cases where distinguished from T21 and T18 cases, with Z statistics for all cases exceeding 3.6. Increasing the sequencing depth to 410,000 counts per sample substantially improved separation of aneuploid and average-risk cases. A further increase to 620,000 counts per sample resulted in only marginal improvement. This depth of sequencing represents less than 5% of that required by massively parallel shotgun sequencing approaches. CONCLUSION: Digital analysis of selected regions enables highly accurate, cost efficient, and scalable noninvasive fetal aneuploidy assessment.

Thromboelastography in the assessment of bleeding following surgery for congenital heart disease.

BACKGROUND: Perioperative bleeding is common in pediatric cardiac surgery patients. Traditional laboratory tests do not adequately characterize coagulation derangements in patients with bleeding. We sought to establish preoperative thromboelastography parameters in children prior to cardiopulmonary bypass, to compare thromboelastography assessment with standard coagulation parameters postoperatively, and to assess thromboelastography in children with significant hemorrhage. METHODS: Sixty patients requiring cardiopulmonary bypass were enrolled in a prospective observational study of perioperative thromboelastography. Thromboelastography measures were obtained preoperatively, intraoperatively after protamine administration, upon admit to the intensive care unit, and when patients were treated for bleeding. Thromboelastography measures were not used for clinical care. Postoperative thromboelastography measurements were compared with the standard coagulation parameters. Intraoperative thromboelastography, postoperative thromboelastography, and clinical outcomes were compared among patients who did and did not have significant postoperative bleeding. RESULTS: Preoperative thromboelastography parameters were similar to other published normal values for pediatric patients. Transfusion recommendations based on thromboelastography measurements were significantly different from those based on the standard coagulation testing. Thromboelastography measures after initial protamine administration were significantly different in patients with postoperative bleeding. This difference was not present upon arrival to the intensive care unit. Patients with significant bleeding tended to cease bleeding when clinical interventions were in agreement with recommendations based on thromboelastography. CONCLUSIONS: Pediatric patients with significant postoperative bleeding after surgery are more likely to have abnormal thromboelastography early after cessation of cardiopulmonary bypass. Thromboelastography illustrates derangements in the coagulation system and may aid in the treatment of postoperative bleeding.

Do correlates of dual use by American Indian and Alaska Native Veterans operate uniformly across the Veterans Health Administration and the Indian Health Service?

OBJECTIVE: To determine if the combined effects of patient-level (demographic and clinical characteristics) and organizational-level (structure and strategies to improve access) factors are uniformly associated with utilization of Indian Health Service (IHS) and/or Veterans Health Administration (VHA) by American Indian and Alaska Native (AIAN) Veterans to inform policy which promotes dual use. METHODS: We estimated correlates and compared two separate multilevel logistic regression models of VHA-IHS dual versus IHS-only and VHA-IHS dual versus VHA-only in a sample of 18,892 AIAN Veterans receiving care at 201 VHA and IHS facilities during FY02 and FY03. Demographic, diagnostic, eligibility, and utilization data were drawn from administrative records. A survey of VHA and IHS facilities defined availability of services and strategies to enhance access to healthcare for AIAN Veterans. RESULTS: Facility level strategies that are generally associated with enhancing access to healthcare (e.g., population-based services and programs, transportation or co-location) were not significant factors associated with dual use. In both models the common variable of dual use was related to medical need, defined as the number of diagnoses per patient. Other significant demographic, medical need and organizational factors operated in opposing manners. For instance, age increased the likelihood of dual use versus IHS-only but decreased the likelihood of dual use versus VHA-only. CONCLUSIONS: Efforts to enhance access through population-based and consumer-driven strategies may add value but be less important to utilization than availability of healthcare resources needed by this population. Sharing health records and co-management strategies would improve quality of care while policies allow and promote dual use.

A survey-based assessment of United States clinical laboratory response to the 2009 H1N1 influenza outbreak.

CONTEXT: The recent outbreak of pandemic influenza created enormous economic, logistical, and analytical challenges for clinical laboratories. Laboratory response represented a critical element in the care of affected patients, but little has been published regarding this aspect of the pandemic. OBJECTIVE: To assess the overall response of clinical diagnostic laboratories across the United States to the initial phase of the 2009 H1N1 influenza A pandemic. DESIGN: A 24-question survey was developed and distributed by e-mail to determine current influenza testing practices and how those practices were changed in response to the outbreak of 2009 H1N1 influenza. The survey was distributed to participants in the College of American Pathologists proficiency testing programs related to viral diagnostics. Survey questions focused on laboratory safety, communication of results, testing volume and resources, and whether changes in resource allocation or laboratory practice were anticipated in preparation for the 2009-2010 influenza season. RESULTS: A total of 24.3% (931) of laboratories responded to the survey. Overall, few laboratories reported changes in methodology in response to the 2009 H1N1 influenza outbreak, although, notably, the number of centers using molecular amplification methods more than doubled, from 41 to 91. Turn-around time for result reporting and safety methods used were largely as expected for individual testing modalities. Shortages in staffing, testing supplies, and personal protective equipment were reported, but most sites were able to maintain operations and did not feel that patient care was negatively affected. CONCLUSION: This report provides a comprehensive picture of clinical laboratory responses in the early stages of the 2009 H1N1 influenza pandemic. These data should assist in the continued laboratory management of this outbreak and in planning for future emerging infections.

Your workers may be contingent but your liability for them is certain: Part III: other employment issues.

Hiring contingent workers can significantly help health care employers reduce labor costs while maintaining the staff required for quality patient care. However, a number of federal laws create legal land mines that await the unsuspecting employer. This article, the concluding part of a 3-part examination of contingent employment, addresses additional issues including benefits, tax implications, workers' compensation, contract considerations, and the screening of potential staffing partners.
