<h3>Quality Indicator Bank</h3>
<p class="mb-3">The <strong>Nordic Lung Cancer Quality Indicator Bank</strong> is a curated set of candidate quality indicators for the Nordic diagnostic pathway, grouped by screening, diagnosis, MDT and core outcomes. These are proposals for the Nordic community to prioritise — rating and discussion take place on LinkedIn, and agreed indicators feed the <strong>NTOG Nordic common data elements</strong>. Candidate indicators, not finalised standards.</p>

<h2>Key differences</h2>
<div class="content-card">
<ul class="compact-list">
<li><strong>Structure:</strong> Sweden and Norway use unified national programmes, while Denmark uses modular disease- and modality-specific documents.</li>
<li><strong>Implementation:</strong> Sweden and Norway are closely linked to national healthcare pathways. Denmark is strongly specialty-group driven.</li>
<li><strong>Accessibility:</strong> Sweden, Norway and Denmark are openly accessible. Finland requires professional login.</li>
<li><strong>Granularity:</strong> Denmark provides the most subspecialised document structure. Sweden offers the most comprehensive single-programme format.</li>

<h2>Frequently asked questions</h2>
<div class="row g-4 mt-1">
<div class="col-lg-6">
<h3 class="h5">Is there a single unified Nordic lung cancer treatment guideline?</h3>
<p>No. There is currently no single unified Nordic lung cancer treatment guideline; each Nordic country has its own national guideline system. NTOG supports harmonisation by providing access to the national guidelines, highlighting differences and identifying areas suitable for Nordic alignment.</p>
</div>
<div class="col-lg-6">
<h3 class="h5">How does NTOG support guideline harmonisation?</h3>
<p>NTOG provides access to all the Nordic national guidelines and identifies areas suitable for Nordic alignment — including a Nordic Lung Cancer Quality Indicator Bank for community discussion. NTOG links to the national guidelines but does not restate or compare them; treatment guidance remains nationally governed.</p>
</div>
<div class="col-lg-6">
<h3 class="h5">Is NTOG working on lung cancer screening guidance?</h3>
<p>Yes. NTOG members are working on Nordic collaboration in lung cancer screening and pulmonary nodule follow-up, including implementation of low-dose CT screening, management of incidental pulmonary nodules, and development of a Pan-Nordic approach.</p>
