State procurement law: facilitating the collaboration between health department and school of public health.

The mark of an "academic health department" includes shared activity by academic and practice partners sustained over time. Despite a long history of productive interactivity, the Pennsylvania Department of Health and the University of Pittsburgh's Graduate School of Public Health often faced administrative hurdles in contracting for projects of mutual interest. Seeking to overcome these hurdles, the Commonwealth of Pennsylvania and the University of Pittsburgh's Graduate School of Public Health negotiated a Master Agreement on the basis of statutes designating both as "public procurement units." This provided a template for project specifications, standard financial terms, and a contracting process. Since taking effect, the Master Agreement has supported projects in policy development, capacity building, workforce development, program evaluation, data analysis, and program planning. This experience suggests an approach potentially useful for other states and localities seeking to solidify academic health department partnerships either envisioned for the future or already in place.

The importance of nursing homes in the spread of methicillin-resistant Staphylococcus aureus (MRSA) among hospitals.

BACKGROUND: Hospital infection control strategies and programs may not consider control of methicillin-resistant Staphylococcus aureus (MRSA) in nursing homes in a county. METHODS: Using our Regional Healthcare Ecosystem Analyst, we augmented our existing agent-based model of all hospitals in Orange County (OC), California, by adding all nursing homes and then simulated MRSA outbreaks in various health care facilities. RESULTS: The addition of nursing homes substantially changed MRSA transmission dynamics throughout the county. The presence of nursing homes substantially potentiated the effects of hospital outbreaks on other hospitals, leading to an average 46.2% (range, 3.3%-156.1%) relative increase above and beyond the impact when only hospitals are included for an outbreak in OC's largest hospital. An outbreak in the largest hospital affected all other hospitals (average 2.1% relative prevalence increase) and the majority (~90%) of nursing homes (average 3.2% relative increase) after 6 months. An outbreak in the largest nursing home had effects on multiple OC hospitals, increasing MRSA prevalence in directly connected hospitals by an average 0.3% and in hospitals not directly connected through patient transfers by an average 0.1% after 6 months. A nursing home outbreak also had some effect on MRSA prevalence in other nursing homes. CONCLUSIONS: Nursing homes, even those not connected by direct patient transfers, may be a vital component of a hospital's infection control strategy. To achieve effective control, a hospital may want to better understand how regional nursing homes and hospitals are connected through both direct and indirect (with intervening stays at home) patient sharing.

Data for preparedness metrics: legal, economic, and operational.

Tracking progress toward the goal of preparedness for public health emergencies requires a foundation in evidence derived both from scientific inquiry and from preparedness officials and professionals. Proposed in this article is a conceptual model for this task from the perspective of the Centers for Disease Control and Prevention-funded Preparedness and Emergency Response Research Centers. The necessary data capture the areas of responsibility of not only preparedness professionals but also legislative and executive branch officials. It meets the criteria of geographic specificity, availability in standardized and reliable measures, parameterization as quantitative values or qualitative distinction, and content validity. The technical challenges inherent in preparedness tracking are best resolved through consultation with the jurisdictions and communities whose preparedness is at issue.

The adaptive response metric: toward an all-hazards tool for planning, decision support, and after-action analytics.

Local health departments are organized, resourced, and operated primarily for routine public health services. For them, responding to emergencies and disasters requires adaptation to meet the demands of an emergency, and they must reallocate or augment resources, adjust work schedules, and, depending on severity and duration of the event, even compromise routine service outputs. These adaptations occur to varying degrees regardless of the type of emergency or disaster. The Adaptive Response Metric was developed through collaboration between a number of California health departments and university-based preparedness researchers. It measures the degree of "stress" from an emergency response as experienced by local health departments at the level of functional units (eg, nursing, administration, environmental services). Pilot testing of the Adaptive Response Metric indicates its utility for emergency planning, real-time decision making, and after-action analytics.

Using Bayesian influence diagrams to assess organizational performance in 4 California county health departments, April-July 2009.

A Bayesian influence diagram is used to analyze interactions among operational units of county health departments. This diagram, developed using Bayesian network analysis, represents a novel method of analyzing the internal performance of county health departments that were operating under the simultaneous constraints of budget cuts and increased demand for services during the H1N1 threat in California, April-July 2009. This analysis reveals the interactions among internal organizational units that degrade performance under stress or, conversely, enable a county health department to manage heavy demands effectively.

Geospatial analytics to evaluate point-of-dispensing sites for mass immunizations in Allegheny County, Pennsylvania.

CONTEXT: Public health agencies use mass immunization locations to quickly administer vaccines to protect a population against an epidemic. The selection of such locations is frequently determined by available staffing levels and in some places, not all potential sites can be opened, often because of a lack of resources. Public health agencies need assistance in determining which n sites are the prime ones to open given available staff to minimize travel time and travel distance for those in the population who need to get to a site to receive treatment. OBJECTIVE: Employ geospatial analytical methods to identify the prime n locations from a predetermined set of potential locations (eg, schools) and determine which locations may not be able to achieve the throughput necessary to reach the herd immunity threshold based on varying R0 values. DESIGN: Spatial location-allocation algorithms were used to select the ideal n mass vaccination locations. SETTING: Allegheny County, Pennsylvania, served as the study area. MAIN OUTCOME MEASURES: The most favorable sites were selected and the number of individuals required to be vaccinated to achieve the herd immunity threshold for a given R0, ranging from 1.5 to 7, was determined. Locations that did not meet the Centers for Disease Control and Prevention throughput recommendation for smallpox were identified. RESULTS: At R0 = 1.5, all mass immunization locations met the required throughput to achieve the herd immunity threshold within 5 days. As R0s increased from 2 to 7, an increasing number of sites were inadequate to meet throughput requirements. CONCLUSIONS: Identifying the top n sites and categorizing those with throughput challenges allows health departments to adjust staffing, shift length, or the number of sites. This method has the potential to be expanded to select immunization locations under a number of additional scenarios.

School closure as an influenza mitigation strategy: how variations in legal authority and plan criteria can alter the impact.

BACKGROUND: States' pandemic influenza plans and school closure statutes are intended to guide state and local officials, but most faced a great deal of uncertainty during the 2009 influenza H1N1 epidemic. Questions remained about whether, when, and for how long to close schools and about which agencies and officials had legal authority over school closures. METHODS: This study began with analysis of states' school-closure statutes and pandemic influenza plans to identify the variations among them. An agent-based model of one state was used to represent as constants a population's demographics, commuting patterns, work and school attendance, and community mixing patterns while repeated simulations explored the effects of variations in school closure authority, duration, closure thresholds, and reopening criteria. RESULTS: The results show no basis on which to justify statewide rather than school-specific or community-specific authority for school closures. Nor do these simulations offer evidence to require school closures promptly at the earliest stage of an epidemic. More important are criteria based on monitoring of local case incidence and on authority to sustain closure periods sufficiently to achieve epidemic mitigation. CONCLUSIONS: This agent-based simulation suggests several ways to improve statutes and influenza plans. First, school closure should remain available to state and local authorities as an influenza mitigation strategy. Second, influenza plans need not necessarily specify the threshold for school closures but should clearly define provisions for early and ongoing local monitoring. Finally, school closure authority may be exercised at the statewide or local level, so long as decisions are informed by monitoring incidence in local communities and schools.

Preparedness for pandemics: does variation among states affect the nation as a whole?

OBJECTIVE: Since states' public health systems differ as to pandemic preparedness, this study explored whether such heterogeneity among states could affect the nation's overall influenza rate. DESIGN: The Centers for Disease Control and Prevention produced a uniform set of scores on a 100-point scale from its 2008 national evaluation of state preparedness to distribute materiel from the Strategic National Stockpile (SNS). This study used these SNS scores to represent each state's relative preparedness to distribute influenza vaccine in a timely manner and assumed that "optimal" vaccine distribution would reach at least 35% of the state's population within 4 weeks. The scores were used to determine the timing of vaccine distribution for each state: each 10-point decrement of score below 90 added an additional delay increment to the distribution time. SETTING AND PARTICIPANTS: A large-scale agent-based computational model simulated an influenza pandemic in the US population. In this synthetic population each individual or agent had an assigned household, age, workplace or school destination, daily commute, and domestic intercity air travel patterns. MAIN OUTCOME MEASURES: Simulations compared influenza case rates both nationally and at the state level under 3 scenarios: no vaccine distribution (baseline), optimal vaccine distribution in all states, and vaccine distribution time modified according to state-specific SNS score. RESULTS: Between optimal and SNS-modified scenarios, attack rates rose not only in low-scoring states but also in high-scoring states, demonstrating an interstate spread of infections. Influenza rates were sensitive to variation of the SNS-modified scenario (delay increments of 1 day versus 5 days), but the interstate effect remained. CONCLUSIONS: The effectiveness of a response activity such as vaccine distribution could benefit from national standards and preparedness funding allocated in part to minimize interstate disparities.

Would school closure for the 2009 H1N1 influenza epidemic have been worth the cost?: a computational simulation of Pennsylvania.

BACKGROUND: During the 2009 H1N1 influenza epidemic, policy makers debated over whether, when, and how long to close schools. While closing schools could have reduced influenza transmission thereby preventing cases, deaths, and health care costs, it may also have incurred substantial costs from increased childcare needs and lost productivity by teachers and other school employees. METHODS: A combination of agent-based and Monte Carlo economic simulation modeling was used to determine the cost-benefit of closing schools (vs. not closing schools) for different durations (range: 1 to 8 weeks) and symptomatic case incidence triggers (range: 1 to 30) for the state of Pennsylvania during the 2009 H1N1 epidemic. Different scenarios varied the basic reproductive rate (R(0)) from 1.2, 1.6, to 2.0 and used case-hospitalization and case-fatality rates from the 2009 epidemic. Additional analyses determined the cost per influenza case averted of implementing school closure. RESULTS: For all scenarios explored, closing schools resulted in substantially higher net costs than not closing schools. For R(0) = 1.2, 1.6, and 2.0 epidemics, closing schools for 8 weeks would have resulted in median net costs of $21.0 billion (95% Range: $8.0 - $45.3 billion). The median cost per influenza case averted would have been $14,185 ($5,423 - $30,565) for R(0) = 1.2, $25,253 ($9,501 - $53,461) for R(0) = 1.6, and $23,483 ($8,870 - $50,926) for R(0) = 2.0. CONCLUSIONS: Our study suggests that closing schools during the 2009 H1N1 epidemic could have resulted in substantial costs to society as the potential costs of lost productivity and childcare could have far outweighed the cost savings in preventing influenza cases.

The evidence base for effectiveness of preparedness training: a retrospective analysis.

OBJECTIVES: In 2007, the Centers for Disease Control and Prevention (CDC) commissioned an Evidence-Based Gaps Collaboration Group to consider whether past experience could help guide future efforts to educate and train public health workers in responding to emergencies and disasters. METHODS: The Group searched the peer-reviewed literature for preparedness training articles meeting three criteria: publication during the period when CDC's Centers for Public Health Preparedness were fully operational, content relevant to emergency response operations, and content particular to the emergency response roles of public health professionals. Articles underwent both quantitative and qualitative analyses. RESULTS: The search identified 163 articles covering the topics of leadership and command structure (18.4%), information and communications (14.1%), organizational systems (78.5%), and others (23.9%). The number of reports was substantial, but their usefulness for trainers and educators was rated only "fair" to "good." Thematic analysis of 137 articles found that organizational topics far outnumbered leadership, command structure, and communications topics. Disconnects among critical participants--including trainers, policy makers, and public health agencies--were noted. Generalizable evaluations were rare. CONCLUSIONS: Reviews of progress in preparedness training for the public health workforce should be repeated in the future. Governmental investment in training for preparedness should continue. Future training programs should be grounded in policy and practice needs, and evaluations should be based on performance improvement.

Demonstrating excellence in the scholarship of practice-based service for public health.

Practice-based scholarship in public health addresses community health issues. The accredited schools of public health (SPHs) have played a significant role in defining and implementing the multidisciplinary, interprofessional, ecological approach to improving the health and safety of communities through academic public health practice. These schools have addressed the challenges raised by the Institute of Medicine for enhancing academic-practice linkages. The Association of Schools of Public Health (ASPH) established the Council of Public Health Practice Coordinators (Practice Council), whose members are delegates from each of the SPHs accredited by the Council on Education for Public Health (CEPH); there were 40 as of 2008. The Practice Council's priorities are to (1) promote greater commitment to scholarship in public health practice-based research, teaching, and service within SPHs, and (2) facilitate recognition and reward for practice-based scholarship in academic institutions. Extensive alignment of efforts by the Practice Council, SPHs, federal agencies, private institutions, and the practice sector have invigorated scholarship in academic public health practice.

Education for the public health profession: a new look at the Roemer proposal.

Demands for a high level of professionalism in public health practice, and concomitant strengthening of public health education to match 21st-century community challenges provide an opportunity to reconsider the current paradigm for professional degrees in public health. In this article, we consider whether the currently typical public health education meets the requirements of a professional education, examine the current state of public health education, and provide a rationale for renewed emphasis on the doctor of public health (DrPH) degree. We also present one potential three-year DrPH curriculum to stimulate further discussion, while acknowledging the multiple challenges that face any school of public health moving to implement such an education.

A public health training center experience: professional continuing education at schools of public health.

The Public Health Training Center (PHTC) national program was first established at accredited schools of public health in 2000. The PHTC program used the US Health Resources and Services Administration's grants to build workforce development programs, attracting schools as training providers and the workforce as training clients. This article is a reflection on the experience of two schools, whose partnership supported one of the PHTCs, for the purpose of opening a conversation about the future of continuing education throughout schools and degree programs of public health. This partnership, the Pennsylvania & Ohio Public Health Training Center (POPHTC), concentrated its funding on more intensive training of public healthcare workers through a relatively narrow inventory of courses that were delivered typically in-person rather than by distance-learning technologies. This approach responded to the assessed needs and preferences of the POPHTC's workforce population. POPHTC's experience may not be typical among the PHTCs nationally, but the collective experience of all PHTCs is instructive to schools of public health as they work to meet an increasing demand for continuing education from the public health workforce.

Cost-Effective Drug Switch Options After Unsuccessful Treatment With an SSRI for Depression.

OBJECTIVE: Multiple treatment options are available for patients who do not respond to initial treatment for major depressive disorder. Previous results show that bupropion, sertraline, and venlafaxine are comparable in terms of therapeutic effectiveness following unsuccessful treatment with citalopram. In this study, we extended these results by incorporating costs of treatment to determine if one option was more cost-effective relative to others. METHODS: In the STAR*D (Sequenced Treatment Alternatives to Relieve Depression) trial, 727 patients were randomly assigned to a switch drug treatment during level 2; 239 (33%) were assigned to bupropion, 238 (33%) to sertraline, and 250 (34%) to venlafaxine. For each study medication, the total costs included the costs of the medication, other concomitant medication and antidepressants, and health care facility utilization. Effectiveness was measured as remission and response. Cost-effectiveness was assessed as net health benefits. Stochastic analysis was performed by using the bootstrapping method. RESULTS: During level 2, mean medication costs were significantly higher for venlafaxine than for bupropion and sertraline ($968, $607, and $703, respectively). There were no significant differences among the switch medications in costs for other medications and health care facility utilization. Although the total costs were significantly different for the three medications (p=.025), none of the pairwise differences between medications were significant. Also, after jointly estimating costs and effects, the analyses found that net health benefits were not significantly different among the three drugs. CONCLUSIONS: After unsuccessful treatment with citalopram, the switch options of bupropion, sertraline, and venlafaxine were not significantly different from each other in terms of cost-effectiveness.

Cross-sector leadership development for preparedness.

After fall 2001, scientists and professionals recognized the importance of integrating public health with traditional first-response professions in planning and training for disasters. However, operationalizing this approach among professionals in the field confronted barriers that were both inter-cultural and jurisdictional. The Pennsylvania Preparedness Leadership Institute (PPLI) is a collaboration of the Pennsylvania Department of Health and the University of Pittsburgh Center for Public Health Preparedness. Team members are recruited from public health, emergency medicine, emergency management, hospitals, and public safety agencies from each of nine multi-county regions in Pennsylvania. Each team takes on a year-long project that addresses a strategic problem as a focus for capacity-building within its region. Unexpectedly during PPLI's first year in operation, a hepatitis-A outbreak tested whether one regional team could successfully mount the necessary integrated response. This experience, as well as the planned evaluation for PPLI, demonstrated both the successful processes and the positive impact of this integrated leadership training initiative.
