Pandemia De Gripe — Plano De Contingência Nacional Do Sector Da Saúde Para A Pandemia De Gripe

Objectives

Portugal’s National Contingency Plan provides a health-sector framework for preparing for, detecting and responding to influenza pandemics across seasonal, interpandemic, pandemic-alert and pandemic periods. Its overarching purpose is to minimise mortality, illness severity, transmission, social disruption and economic effects, while maintaining essential health and other critical services.[1][2][3][4]

• Strengthen health information, epidemiological surveillance, laboratory capacity and risk assessment to identify novel influenza subtypes, cases, outbreaks and changes in disease impact promptly.[5][6][7]
• Contain sporadic zoonotic infections and delay the entry and spread of a pandemic virus through early detection, isolation, contact management, targeted antivirals, personal protection and proportionate social-distancing measures.[3][8][9]
• Minimise established-pandemic impact by adapting outpatient and inpatient care, maintaining essential services, reducing healthcare-associated transmission, protecting health workers and allocating scarce resources transparently.[8][10][11][12]
• Organise action across four functional areas: health information for risk assessment, including epidemiological surveillance; prevention, containment and control; communication; and evaluation.[13][14][8]
• Deliver specific, interdependent operational plans for public-health measures, outpatient care, inpatient care, vaccines and medicines, communication, health information and evaluation.[1][14][15]
• Maintain plans as flexible instruments that are reviewed and updated in response to epidemiological developments, scientific evidence, technical knowledge and social or technological change.[16][17][14]

The plan frames preparedness as a whole-of-society responsibility: public and private organisations, other ministries, civil society, communities and the population are expected to prepare contingency arrangements, because a pandemic response exceeds the resources of the Ministry of Health alone.[1][14][18]

Priority intervention areas include protecting individuals through hand and respiratory hygiene and personal protective equipment; managing social contact, travel and public gatherings; providing dedicated ambulatory influenza services; preparing hospitals and reference facilities; securing medicines and vaccines; sustaining risk communication; and supporting recovery and learning between pandemic waves.[10][19][20][21][22]

Implementation

Implementation uses a multi-level command-and-control model spanning national, regional, local and institutional levels. The Directorate-General of Health leads the National Contingency Plan and coordinates regional plans, while equivalent committees and operational groups adapt and implement measures within their areas of responsibility.[23][24][25]

• Coordinate strategic direction through the National Influenza Committee, chaired by the Director-General of Health and National Health Authority, and operational delivery through the National Operational Influenza Group, specialist groups and the National Advisory Council.[24][26]
• Assign regional leadership to Regional Health Administrations and Regional Health Authorities, supported by local and institutional influenza committees, operational groups, public-health services, health centres and hospitals.[25][27][28]
• Support autonomous regions to adopt organisational arrangements considered appropriate by their respective governments.[29][3]
• Integrate human and veterinary health authorities, particularly for zoonotic influenza risks, epidemiological investigation and preventive action.[30][14][31]
• Coordinate internationally with the World Health Organization, European Commission, European Centre for Disease Prevention and Control, European surveillance mechanisms and neighbouring Spain.[17][32][33]

The Integrated Influenza Information System, SIIG, is the central information architecture. It is intended to integrate existing clinical, laboratory, mortality, emergency-care, vaccination, pharmacovigilance, medicine, absenteeism and veterinary-information sources, alongside epidemic intelligence, epidemiological investigations and special studies.[6][7][34][35]

• Use SIIG to provide timely information for risk assessment, risk management, early warning, resource planning, decision-making and communication, without unnecessarily duplicating primary data-collection systems.[36][37][38]
• Develop the Information System Supporting Care Provision for Influenza, SIAPC-G, to record influenza-care encounters, follow patients, support electronic prescribing, control antiviral dispensing and prevent duplicate treatment for the same episode.[39][40][41]
• Monitor clinical incidence, virological characteristics, complications, mortality, healthcare use, absenteeism, medicine consumption, vaccine and antiviral effectiveness and safety, and the societal impact of influenza.[42][43][44]

Healthcare delivery is based primarily on existing services, reorganised for surge demand. Dedicated Influenza Attendance Services, known as SAG, provide segregated ambulatory assessment, triage, treatment, referral and follow-up, supported by Saúde 24 telephone triage and local call centres.[2][20][45]Hospitals prepare internal plans, reference hospitals manage suspected zoonotic cases during alert phases, dedicated hospitals may be activated at the start of a pandemic, and wider hospital or field capacity may be used if demand escalates.[46][47][48]

Medicine and vaccine arrangements rely on the Strategic Medicines Reserve for Influenza, managed through the Directorate-General of Health, the National Authority of Medicines and Health Products, the National Institute of Medical Emergency and the Institute for Health Informatics and Financial Management. The reserve includes bulk oseltamivir intended to treat 2.5 million people in phase 6 and provide chemoprophylaxis for priority groups, although the plan does not specify monetary values for this procurement.[49][50][51]

Evaluation is embedded throughout planning and implementation. Internal evaluation is led by the relevant influenza committees and operational groups, while the National Influenza Committee evaluates regional plans, regional committees evaluate local and institutional plans, and international bodies including the European Centre for Disease Prevention and Control may assess the national plan.[52][53][54]Evaluation should examine relevance, implementation, effectiveness, efficiency and impact, communicate findings quickly and use intervals between pandemic waves to correct weaknesses.[55][54]

The source does not specify an overall budget, detailed funding allocations, quantified resource gaps or a consolidated set of numerical performance targets.[3][32][56]

Monitoring & Evaluation

The plan establishes a multi-level monitoring and evaluation system that combines integrated surveillance, risk assessment, periodic plan revision and internal and external review across national, regional, local and institutional levels.[3][52][53]

• Use the Integrated Influenza Information System (SIIG) to integrate clinical, laboratory, mortality, healthcare-use, medicine-consumption, absenteeism, pharmacovigilance and veterinary-surveillance information for risk assessment and decision-making.[6][42][7]
• Combine indicator-based surveillance with event-based epidemic intelligence, drawing on routine data, official reports, media, electronic networks, international sources, news and rumours, then filter and validate signals before initiating investigation or control measures.[57][58][36]
• Monitor influenza through weekly clinical notifications, laboratory surveillance, incidence estimates, virus characterisation, geographical spread, severe complications, mortality, health-service demand and medicine consumption.[59][60][61][62]
• Transmit National Influenza Surveillance System information weekly to the European Influenza Surveillance Scheme, supporting European activity monitoring and early outbreak identification.[59]
• Use SIAPC-G, the Information System Supporting Care Provision for Influenza, to record influenza consultations, follow patients, control antiviral prescribing and dispensing, prevent duplicate prescriptions and contribute data to SIIG.[39][40][41][63]
• Monitor daily mortality, including cause, age, sex and place of residence, and develop absenteeism monitoring among health professionals, school populations and other groups as proxy measures of outbreak impact.[39][40][64]
• Track hospital impact through measurable indicators including urgent attendances, admissions, case fatality, intensive-care demand, occupancy, length of stay, medicine consumption, staff illness and absenteeism.[65]
• Review pandemic scenarios as epidemiological knowledge develops, using modelled cases, consultations, hospitalisations and deaths to guide preparedness, capacity planning and resource allocation.[66][67][68]
• Conduct internal evaluations led nationally by the Directorate-General of Health and National Influenza Committee, with Regional, Local and Institutional Influenza Committees evaluating plans at their respective levels.[3][53]
• Undertake external review of regional plans by the National Influenza Committee, of local and institutional plans by Regional Influenza Committees, and of the national plan by international assessors including the European Centre for Disease Prevention and Control, European Commission and World Health Organization Regional Office for Europe.[53]
• Prepare evaluation plans that define objectives, methodology, standards, data sources, indicators, communication channels, analytical arrangements and evaluation frequency.[69][53][55]
• Conduct concurrent evaluation during plan development, updating and implementation, assess final outcomes and impact after the pandemic, and use intervals between waves to identify weaknesses and implement corrective action.[70][55][21]
• Issue and disseminate evaluation reports containing conclusions and proposals for future action, while using checklists where appropriate to assess plan adequacy, implementation, effectiveness, efficiency and impact.[54]

Although the plan specifies broad monitoring domains, surveillance mechanisms and evaluation responsibilities, most extracts do not provide numerical performance targets, standard reporting templates, comprehensive reporting deadlines or accountability sanctions.[3][69][54]

Costing & Financing

The plan identifies substantial resource needs for pandemic preparedness and response, particularly strategic antiviral and medicine reserves, vaccines, information systems, personal protective equipment, hospital capacity, staffing, communications and logistics, but generally does not quantify budgets or funding gaps.[6][71][72][49]

• Maintain the Strategic Medicines Reserve for Influenza under Directorate-General of Health leadership, with technical and operational management by the National Authority of Medicines and Health Products.[49][50]
• Use national and institutional reserves, decentralised procurement, stock forecasting and controlled prescribing to maintain availability of medicines, personal protective equipment and other consumables.[73][74][75]
• Base antiviral stock requirements on projected weekly illness scenarios and retain bulk oseltamivir centrally until authorised mobilisation and pharmaceutical fractionation.[49][76][77]
• Provide oseltamivir sufficient for treatment of 2.5 million people during pandemic phase 6, alongside post-exposure chemoprophylaxis for priority groups.[51][78]
• Maintain oseltamivir capsules and zanamivir for influenza activity phases 3, 4 and 5, with smaller decentralised stocks held by Autonomous Regions and Regional Health Administrations.[79][78]
• Review the Strategic Medicines Reserve annually and when scientific, clinical, epidemiological or pharmaceutical-supply developments require revision.[76]
• Use stock rotation, annual National Health Service procurement, wholesale distribution and custody agreements to reduce expiry, obsolescence, holding costs and the financial burden of reserve formation.[80][81]
• Assign Regional Health Administrations and health centres responsibility for budgets for Influenza Care Service building works, equipment, consumables and extraordinary-work compensation.[82][83]
• Invest in SIIG infrastructure, communications, user equipment, alternative systems and workforce capacity, recognising that system creation and maintenance require substantial financing.[32][84]
• Consider costs, social disruption, public acceptance and resource availability when selecting isolation, quarantine, travel restrictions, school closures and other public-health measures.[85][86][87]

The plan identifies financing through the General State Budget for the approved national antiviral reserve proposal in 2005, and identifies a Calouste Gulbenkian Foundation-funded epidemiological-surveillance research project, but no monetary allocation is provided for either.[88][89]

No consolidated budget, unit-cost schedule, financing framework, quantified funding gap or formal economic model is specified for the overall contingency plan.[84][72][90]
