Allocation of scarce resources in a pandemic: rapid systematic review update of strategies for policymakers

OBJECTIVE

In pandemics like COVID-19, the need for medical resources quickly outpaces available supply. policymakers need strategies to inform decisions about allocating scarce resources.

STUDY DESIGN AND SETTING

We updated a systematic review on evidence-based approaches and searched databases through May 2020 for evaluation of strategies for policymakers.

RESULTS

The 201 identified studies evaluated reducing demand for healthcare, optimizing existing resources, augmenting resources, and adopting crisis standards of care. Most research exists to reduce demand (n = 149); 39 higher quality studies reported benefits of contact tracing, school closures, travel restrictions, and mass vaccination. Of 28 strategies to augment resources, 6 higher quality studies reported effectiveness of establishing temporary facilities, use of volunteers, and decision support software. Of 23 strategies to optimize existing resources, 12 higher quality studies reported successful scope of work expansions and building on existing interagency agreements. Of 15 COVID-19 studies, 5 higher quality studies reported on combinations of policies and benefits of community-wide mask policies.

CONCLUSION

Despite the volume, the evidence base is limited; few strategies were empirically tested in robust study designs. The review provides a comprehensive overview of the effects of strategies to allocate resources and provides critical appraisal to identify the best available evidence.

The impact of disasters on emergency department resources: review against the Sendai framework for disaster risk reduction 2015-2030

BACKGROUND

Emergency departments (EDs) are often first to feel the intra-hospital effects of disasters. Compromised care standards during disasters eventuate from increased demands on health resources; the facilities, supplies, equipment and manpower imperative for a functioning healthcare facility. Emergency departments must understand the effect of disasters on their health resources. This paper examines the impact on resources within the ED as a result of a disaster and provides a review against the United Nations Office for Disaster Risk Reduction's Sendai Framework for Disaster Risk Reduction 2015-2030 priorities.

METHOD

An integrative literature review design was utilised. Articles were extracted from databases and search engines. The Preferred Reporting Items of Systematic reviews and Meta-Analysis Guidelines for systematic literature reviews were used.

RESULTS

Seven papers met inclusion criteria. Disaster consumable stocking was used to mitigate disaster risk and improve resilience. Logistical challenges were exacerbated by poor building design. Ineffective human resource management, communications failure, insufficient ED space, diminished equipment and supplies and unreliable emergency power sources were described.

CONCLUSIONS

Disaster planning and preparedness strategies can address health resource deficits, increasing ED resilience. Further retrospective case studies are required to greater understand the effects of disasters on ED health resources.

Pattern and spectrum of tornado injury and its geographical information system distribution in Yancheng, China: a cross-sectional study

OBJECTIVES

Few studies of tornado injuries have considered differences related to damage levels and Enhanced-Fujita (EF) scale ratings. This study aimed to evaluate the pattern, spectrum and geographical distribution of injuries related to the Yancheng tornado and provide guidelines for effective emergency medical strategies.

SETTING

The study was conducted at three hospitals which treated patients with injuries related to the tornado in Yancheng, China.

PARTICIPANTS

We obtained the records of 451 patients with tornado-related injuries. Of these, 401 valid trauma medical records were included; 50 other records were excluded for insufficient information. Informed consent was obtained from all patients by telephone.

MAIN OUTCOME MEASURES

We analysed patients' injury sites and types and used the abbreviated injury scale (AIS) to standardise injury severity. Geographical information system and non-parametric tests were used to analyse the effects of geographical factors on casualties.

RESULTS

Women, middle-aged/elderly individuals (age>45 years) and children/adolescents (<18 years) accounted for 51.62%, 77.30% and 12.47% of injured patients, respectively. This caused a dumbbell-shaped age distribution. Head (46.63%), body surface (39.90%) and lower-limb (29.43%) injuries were common, as were soft-tissue injuries (90.77%), fractures (38.90%) and organ damage (19.70%). Minor injuries (AIS=1) were common (60.85%), whereas critical/fatal injuries (AIS≥5) were very rare (2.50%). Although the densities of injury varied among damage levels and EF ratings for different areas, area-wise differences in injury severity (AIS scores) were not significant (p>0.05).

CONCLUSION

We recommend the use of helmets to prevent head injuries caused by tornadoes and suggest prioritising the treatment of high-risk head and multiple-organ injuries. Additionally, medical rescuers should follow the 'same quality and different quantity' principle: the injured in all affected areas should receive equal attention, but numbers of medical personnel should be allocated based on the level of effects from the tornado.

Findings from an Assessment and Inventory of a Regional, Decentralized Stockpile

Stockpiles can aid with healthcare surge that occurs after a disaster, and experts recommend that these caches be assessed at least annually to ensure supply integrity. The purpose of this study was to assess a regional stockpile to determine its viability and readiness. An assessment was performed in the summer and fall of 2016 on a regionally funded stockpile that was decentralized through a regional network of 15 local hospitals. Each supply was assessed to determine whether the correct amount was present, if it was in a safe and usable condition (ie, deployable), and whether it had expired. Stockpiled materials were categorized by the type of supply or equipment for analysis. The percent of deployable materials was calculated for each item, each category of supplies, and for the entire cache. Almost all sites (93.3%, n = 14) reported that they inventory their cache at least once a year. On average, 60.1% of each site's cache materials were present and deployable (range: 22.1%-87.5%). The best-maintained supplies included personal protective equipment (79.4% deployable) and general medical supplies (73.5% deployable). Decontamination equipment and pediatric supplies had the lowest percentages of deployability (29.0% and 37.7%, respectively). Although almost all sites claimed to assess the stockpile annually, results from this study indicate that almost half of the supplies are either missing or in an unusable condition. This not only represents wasted resources, but it could also hinder disaster response, leading to increased morbidity and mortality. Facilities may need to invest in infrastructure to maintain stockpiled materials after purchase to ensure viability.

Surge capacity principles: care of the critically ill and injured during pandemics and disasters: CHEST consensus statement

BACKGROUND

This article provides consensus suggestions for expanding critical care surge capacity and extension of critical care service capabilities in disasters or pandemics. It focuses on the principles and frameworks for expansion of intensive care services in hospitals in the developed world. A companion article addresses surge logistics, those elements that provide the capability to deliver mass critical care in disaster events. The suggestions in this article are important for all who are involved in large-scale disasters or pandemics with injured or critically ill multiple patients, including front-line clinicians, hospital administrators, and public health or government officials.

METHODS

The Surge Capacity topic panel developed 23 key questions focused on the following domains: systems issues; equipment, supplies, and pharmaceuticals; staffing; and informatics. Literature searches were conducted to identify evidence on which to base key suggestions. Most reports were small scale, were observational, or used flawed modeling; hence, the level of evidence on which to base recommendations was poor and did not permit the development of evidence-based recommendations. Therefore, the panel developed expert opinion-based suggestions using a modified Delphi process. Suggestions from the previous task force were also included for validation by the expert panel.

RESULTS

This article presents 10 suggestions pertaining to the principles that should guide surge capacity and capability planning for mass critical care, including the role of critical care in disaster planning; the surge continuum; targets of surge response; situational awareness and information sharing; mitigating the impact on critical care; planning for the care of special populations; and service deescalation/cessation (also considered as engineered failure).

CONCLUSIONS

Future reports on critical care surge should emphasize population-based outcomes as well as logistical details. Planning should be based on the projected number of critically ill or injured patients resulting from specific scenarios. This should include a consideration of ICU patient care requirements over time and must factor in resource constraints that may limit the ability to provide care. Standard ICU management forms and patient data forms to assess ICU surge capacity impacts should be created and used in disaster events.

Disaster preparedness and families of children with special needs: a geographic comparison

Over eleven million children in the United States have special health care needs. These unique needs can burden community and emergency responders after a disaster, complicating rescue and recovery efforts and generating reunification needs. Family disaster preparedness can help to moderate the extent that community resources are utilized by preparing families to be self-sustaining after a disaster and streamline access to medical care when needed. This study explored differences in two populations of families of children with special health care needs to determine if geographic differences exist in preparedness levels and whether a brief education intervention would prove successful in increasing baseline preparedness levels across both populations. A brief education intervention was delivered by trained community health educators to 210 families of children with special health care needs. A quasiexperimental pre-posttest design was used to compare baseline preparedness levels and 1 month follow-up levels. Although there was no difference in preparedness levels based on geographic location, both populations demonstrated a statistically significant increase in preparedness levels post-intervention. This study provides additional evidence that a brief education intervention helps to increase preparedness levels among families of children with special health care needs.
