”Ventetid” for start på strålebehandling ved hoved-hals kræft i Danmark 1968-2008

Konklusion 6 marts 2007:

Hvad har vi lært?

Der er ingen data der støtter at ventetid er harmløs og uden forringelse af prognosen – derimod er der stort set entydige data som klart viser at selv kort ventetid indebærer en risiko for en markant reduktion af mulighederne for helbredelse

– det er derfor videnskabeligt bevist (hvor det er undersøgt) at ventetid medfører en forringelse for helbredelsesmulighederne og dermed en dårligere prognose

– formodentlig skal en væsentlig del af det efterslæb vi har i Danmark vedrørende resultater af cancerbehandling ses i lyset heraf – både i form af ventetider for nydiagnostiserede patienter og pga. manglende udnyttelse af de screenings-muligheder der foreligger

DAHANCA -databaseWHAT’S IMPORTANT

COLLECTION with a “Carrot” – not a stick

Obviously benefit for the persons who input data

Only collect what will be used (we miss it anyway)

Access for the users (they “own” the data)

Alert and control system

Feedback (control, verification, revision)

(remember: a data base is a “living” thing)

DAHANCA.dk

DAHANCA -databaseWHAT’S IMPORTANT (cont..)

Easy input and (research) access (to own data)

Webbased – accessible from all computers

Flexible and not to big

Quality

Connected with biobank (DCB?)

Good clinical data from protocolized studies with associated biobank material is worth more than gold)

DAHANCA.dk

DAHANCA -databaseWHAT’S IMPORTANT (cont..)

USE IT(e.g. annual question)

Ph.d. studies, publications…

DAHANCA.dk

>150 publicationer based on the database4 DMSc and 18 (6 ongoing) Ph.d studies.

Web site for extract of database

Meget begrænset mulighed for elektronisk opfølgning af data!

Paradox: Vi har lov til at kende data, - vi har de praktiske og tekniske muligheder for at fådata - men det må vi ikke elektronisk (og de er ikke længere på papir).

Dette er de kliniske (kræft) databasers største trussel –og den er tæt på at være fatal.
