Background

An influenza pandemic is a rare, high impact event. Few have occurred. Governments must plan, because the health, economic, and social impact of a pandemic can be sudden and severe. Challenges include dealing with inherent uncertainty and anticipating the “worst-case scenario” [1]. Pandemic plans assume that many conditions and circumstances will remain under control, and that needed resources will be available.

Each government should update its legal authority to promote alignment with the directive of the World Health Organization’s (WHO) Global Agenda on Influenza for the development and implementation of national preparedness plans [2, 3]. Most pandemic plans use a worst-case scenario with features drawn from 1918 [4,5,6,7]. Methods for anticipating possible consequences based on these estimates extend beyond traditional strategic planning [8,9,10].

The scope of pandemic plans is influenced by culture, beliefs, and perspectives of the planner and of the intended users [11]. Soon after its 56th World Health Assembly in 2003, a WHO directive called for member states to prepare for influenza pandemics [12]. Hong Kong published the first (unofficial) plan in 1997 following the avian influenza outbreak there. Since then, governments worldwide have drawn up pandemic plans based on the assumption of a pandemic arising from highly pathogenic H5N1 (“bird flu”). Aside from dealing with increased morbidity and mortality and strengthening the ‘surge capacity’ of a health system, the next most crucial task is the prevention or mitigation of any interruption of “essential services”. These include continuation of power supplies, water, transport, and telecommunication upon which business continuity depends.

In its Comparative analysis of national pandemic influenza preparedness plans, the WHO listed the following elements of the assessment of the state or quality of preparedness plans: (1) planning and coordination, (2) situation monitoring and assessment, (3) prevention and containment, (4) health system response, and (5) communication [13]. A subsequent analysis of European plans found many plans fail to address preparation for disruption of essential services [14].

World Health Organization called for plans to guide users in three key domains: health and medical intervention, continuity of organisation, and crisis communication. Under health, plans should address measures relevant to public health including vaccination, hygiene, quarantine, and drugs such as antivirals. Under organisation, plans should address responsibilities of authorities plus legal and administrative frameworks. This includes essential supplies, services, and staff. Crisis communication should be part of the overall governance and management of any disaster [15]. Plans often assume that hospitals will remain operational and will be able to attend to the quickly rising number of patients; in addition, plans address hospital surge capacity during pandemic.

We aimed to review official Australian pandemic preparedness planning documents in place at the time of the 2009 pandemic; to identify areas of consistencies, inconsistencies, and gaps; to determine clarity and ease of interpretation for end-users; and to compare thoroughness of planning for health and medical functions versus critical infrastructure.

Methods

We identified and collected documents from 2008 to 2009 that indicated in their titles relevance for pandemic influenza preparedness during the pandemic of 2009. We conducted a review of Australian and State Government sources in print, on official websites, and from other internet resources. We reviewed plans by supranational organisations such as the WHO.

We constructed a typology based on types of pandemic planning documents [16]. We identified subsets of organisational units as ‘authors’ including departmental units with jurisdiction over pandemic-related activities, such as ‘Health’, ‘Transport’, ‘Attorney-General’s Department’. We found 160 documents. Documents at State, Territory, and National levels were retained for the study. We categorised the plans using internationally accepted planning standards informed by the International Organization for Standardization (ISO) [17, 18], the literature on project management [19], and pandemic planning controls [20,21,22].

Following criteria and a checklist established by WHO [21, 23], we sought to assess plans representing state, Commonwealth, and supranational bodies on details for planning health and essential services. We reviewed each document for its coverage of (1) health and medical intervention, (2) continuity of the organisation, and (3) crisis communication.

We also assessed consideration of specific needs of Aboriginal and Torres Strait Islanders, and populations at-risk for complications of influenza [24]. We searched Australian plans because of reports that the needs of these populations had been overlooked in pandemic planning [25].

We used the methodological approach of Mounier-Jack et al. in their analysis of European plans [26]. We considered a document to be relevant to pandemic preparedness if it specified pandemic planning as its purpose, and if it had been issued by the Australian Federal or State Governments, and was current just before or during in the year 2009.

Overall, we selected 10 Australian preparedness plans. Our sample contained two Australian Government plans and one from each of the eight Australian states or territories (see listing of plans in Tables 2 and 3). We examined each for its usefulness for informing readers about health- and non-health-related measures in Australia.

Scoring of plans

Pandemic preparedness plans are meant to cover a wide range of topics including readiness of hospitals and availability of health supplies, especially of relevant drugs and pharmaceuticals usually stockpiled in anticipation. We classified these as ‘health criteria’. We classified as ‘non-health criteria’ the technical and organisational aspects (for example, equipment and communication, respectively) and a range of underlying or interconnected enabling systems (“essential goods and services”).

We assigned six categories to rate plans against the WHO Influenza Pandemic Preparedness Checklist [23]. We ranked plans under two categories: (a) guidance related to hygiene, health, and treatment (“health factors planning”) and (b) guidance related to essential/critical systems (“critical systems’ planning”). We applied a scale to assess a plan’s standard interventions for pandemic planning: “personal hygiene”, “social distancing”, “vaccines”, antivirals”, “antibiotics”, “pneumococcal vaccines”, and instructions regarding the use of drugs. Pneumococcal vaccine and antibiotics prevent and treat secondary bacterial infections that may result from pandemic influenza. We also checked for statements regarding the special needs of Aboriginal and Torres Strait Islander people in each plan [27].

We scored plans next on their references to external systems, and critical and essential services. Table 1 shows major dimensions of the infrastructure components and systems summarised.

Table 1 Essential infrastructure

Two members of our team independently scored the categories (RI, CRM). Where the reviewers’ assessments differed by two points or more, they discussed until they were able to reach agreement. Scores for each criterion ranged from a possible 0–3, with 3 representing complete and comprehensive instructions, 2 making general remarks about the topic, 1 offering at least the keyword in the text, and 0 representing no mention of it. The maximum possible score for health criteria for any plan was 21, and for non-health criteria was 18. While there is some subjectivity in scoring 1–3, the score of zero was not contestable, as it reflects the absence of consideration of a variable.

Results

The search for planning documents yielded 160 items from which we identified 10 as eligible. In reviewing those, we found health interventions to have been covered more comprehensively than essential services, although most noted the importance of essential services. Each approached pandemic planning as a serious undertaking. Several offered strategies to reduce or prevent death and disease.

Table 2 shows the health-related criteria. Most of the plans assumed preparation would be for a worst-case scenario based on the 1918 experience. We found extensive variations in the level of detail on personal hygiene, social distancing (to avoid transmission), and the use of medications and drugs. While some documents (Plans 1, 3, and 5) emphasised hygiene or vaccination (Plan 4), others (Plans 2, 6, 7, and 8) only mentioned it or some pointed to other sources (Table 2). The most comprehensive plan, Plan 5 (Victoria) [28], presented readers with consistent details on “external systems” and all “health-related intervention” options including antibiotics and pneumococcal vaccines. The latter two topics were not mentioned by almost half of the reviewed plans.

Table 3 shows critical infrastructure considerations. All but two plans (Plans 5, 8) failed to provide details of critical/essential systems, apparently assuming such systems would remain intact (Table 3). Plans did not provide adequate consideration of potential failure of critical elements during an emergency. One (Plan 5) that introduced ‘infrastructure’ noted it “assists individuals and communities in the management of their daily lives, but also forms an important role of community identity”. Four out of the 10 plans made no reference to the need for power and utilities or for any preparation to ensure their availability. Two plans (6 and 7) did not mention “essential systems”.

Seven of the 10 plans failed to mention computerised systems necessary for communication and databases. Four plans (2, 3, 4, and 7) included very little about the importance of electricity supplies and telecommunications. Most proposed preparedness measures that relied on the availability of uninterrupted critical services such as internet or computers. The pandemic outbreak of 2009 helps us to understand the importance of reliable and continuous information and media interaction and crisis communication (Table 3). This feature appeared prominently in non-pandemic-related disaster plans. Only one (Plan 2) discussed the need for crisis communication in detail and provided instructions. No plans mentioned the use of social media.

Staffing and absenteeism. Two plans did not mention staff absenteeism during pandemics (6 and 9). Staffing in hospitals and stockpiling of drugs, often discussed in conjunction with transport, are closely related to health; three plans (1, 5, and 8) discussed them in detail.

Plans other than Plan 2 appeared to be ‘top-down’, describing “State governance arrangements” or “ how government will work” rather than what steps organisations should take. One plan provided “additional information” in appendices or as attachments (Plan 10) [29].

Overall, information about “health-related interventions”, especially influenza vaccination, was better than that about “external systems”. Four plans ranked in the bottom half in both categories. Five of ten plans did not mention pneumococcal vaccines, and 6 of 10 did not mention antibiotics.

The same plans that scored high on “health-related intervention” also contained the most information on “essential services” (Plans 3 and 5). Plan 5 (Victoria) ranked highest for both health (18/21 points) and non-health (11/18 points). Scores across plans ranged from 6 to 18 for health, and 2–11 for non-health criteria. Scores were low for Aboriginal and Torres Strait Islander needs in pandemic planning (Table 2). Indigenous people were not mentioned at all in 3 plans nor covered adequately in 2 other plans, and no plan received a score of 3 for this criterion.

Discussion

The influenza pandemic plans during the 2009 pandemic showed considerable variation in detail, consistency, completeness, and usability. Planning for critical infrastructure ranked consistently lower than the health coverage, making this as an area for improvement. A lack of clarity about the intended end-user (hospital manager, clinician, or health department policy maker) further limits the usefulness of these plans.

The WHO had recommended planners to pay “attention to the need to ensure adequate supplies of vaccine, antiviral agents, and other vital medicines” [12, 30]. Yet coverage of pharmaceutical interventions varied widely, with some (antibiotics and pneumococcal vaccines) entirely omitted in several plans. Secondary bacterial infections are a major cause of preventable death and illness during pandemics, causing up to 30% of deaths [31]; therefore, prevention and treatment of bacterial complications should be routinely covered in pandemic plans.

Staffing and stockpiling of drugs dominate the interpretation of what might be considered under “essential services” with little attention to the need for power and telecommunications. Planners focused on the health system and assumed that the critical infrastructure upon which the health system depends would function normally. This is a vulnerability for continuity of any health system.

The literature addresses crisis communication as central to disaster management [15, 32, 33] but only one plan addressed this well. Planners have not factored in the arrival and availability of internet-based social media and their potential usefulness or impact [34, 35].

The pandemic of 2009 caused disproportionate morbidity and mortality in Indigenous people [36]. The “Australian National Action Plan for Human Influenza Pandemic” [37] had simply overlooked Aboriginal and Torres Strait Islanders, a finding consistent with reports by other sources that these populations had been “forgotten” in core Australian planning documents [27]. Yet Aboriginal and Torres Strait Islander people are at higher risk for influenza and its complications and with an overall higher exposure to communicable diseases [38].

As early as 2006, the National Aboriginal Community Controlled Health Organisation had called for specific preparedness for Aboriginal and Torres Strait Islander populations, fearing they would be disproportionally affected in a pandemic [39]. The geographical remoteness of many communities and their often low socio-economic status would make any outbreak potentially devastating [40]. Flint et al. showed a “disproportionate impact” with significant higher hospitalisation rates [41], and members of the Aboriginal population representing 20% of confirmed cases of influenza [42]. Massey et al. stated that “It was clear to many respondents that the policies and plans had been developed without respectful engagement with communities and this was a barrier to their acceptance and implementation” [25].

Health care providers found generic planning documents to be useful and applied them in the field [43]. Revised versions of Australian planning documents [44] addressed the specific needs of vulnerable minorities [42, 45]. In the Australian Health Management Plan for Pandemic Influenza current in 2017, at-risk groups including the Aboriginal and Torres Strait Islander people are included, with recommendations for tailored health care services and other services [46].

Absenteeism of staff working in health care facilities dominates preparedness and preferential vaccination is often the top item mentioned [47]. Essential services outside of the health system may also be impacted by high rates of absenteeism, a possibility unaccounted for by many plans [48]. Any systemic failures could cripple systems that rely on power and telecommunication, and this in turn could disable the health system [49, 50]. Governments do not own, nor have direct control over, most services and businesses that run components of “critical infrastructure” [51]. Even if able to intervene, in a crisis government may not have the expertise or resources to keep privatised systems operational should their owners become unavailable [52].

A limitation of most plans is lack of rigorous version control and vulnerability to political electoral cycles. Within less than 1 year from 2009 to 2010, almost half of all Australian State and Federal government website locations had changed, sometimes after an election, when the entire departments vanished or changed names. The Internet itself is a critical resource and highly dependent on others, something users and planners need to consider.

Preparedness plans need to incorporate established standards for good governance and business continuity. They need to apply evidence-based instruments and specify the intended audience or end-user [53, 54]. Most plans do not include ‘return to normal’ guidance. That could be particularly useful for health services [55].

Limitations of this study include subjectivity in scoring of plans, despite our method for bringing the scorers to agreement through discussion. There are other vulnerable groups during a pandemic besides Indigenous people, such as pregnant women, health workers, the immunosuppressed; we did not examine attention to such groups, but this is a research gap that should be addressed.

Conclusion

Coordination, rationalisation, and the connection of pandemic planning across sectors and jurisdictions would result in better preparedness. Plans should apply standards; be consistent, easy to access, read, and comprehend; and address infrastructure domains of preparedness. Planners should include and consult with all categories of stakeholders, especially those most vulnerable. Prevention and treatment of bacterial pneumonia must be routinely included in pandemic plans.

The plans we reviewed at the onset of the 2009 pandemic have since been revised several times, including in late 2009, to address gaps which became apparent during the pandemic [51]. Planning for rare events of potentially high impact requires resources and tight cooperation. Despite availability of relevant knowledge, many plans appear to work from unsubstantiated assumptions and fail to consider proven methods. A single plan or a series of consistent plans, which are accessible, cover health and non-health factors, and specify intended end-users would improve pandemic preparedness.
