Toelichting

Embolisatie bij patiënten met pelvic venous disorder

Uitkomst 2: Geen substantiële financiële gevolgen

Uit de toetsing volgt dat de aanbeveling(en) niet breed toepasbaar zijn (<5.000 patiënten) en daarom naar verwachting geen substantiële financiële gevolgen zal hebben voor de collectieve uitgaven.

GRADE

Definitie

Hoog

• er is hoge zekerheid dat het ware effect van behandeling dichtbij het geschatte effect van behandeling ligt;
• het is zeer onwaarschijnlijk dat de literatuurconclusie klinisch relevant verandert wanneer er resultaten van nieuw grootschalig onderzoek aan de literatuuranalyse worden toegevoegd.

Redelijk

• er is redelijke zekerheid dat het ware effect van behandeling dichtbij het geschatte effect van behandeling ligt;
• het is mogelijk dat de conclusie klinisch relevant verandert wanneer er resultaten van nieuw grootschalig onderzoek aan de literatuuranalyse worden toegevoegd.

Laag

• er is lage zekerheid dat het ware effect van behandeling dichtbij het geschatte effect van behandeling ligt;
• er is een reële kans dat de conclusie klinisch relevant verandert wanneer er resultaten van nieuw grootschalig onderzoek aan de literatuuranalyse worden toegevoegd.

Zeer laag

• er is zeer lage zekerheid dat het ware effect van behandeling dichtbij het geschatte effect van behandeling ligt;
• de literatuurconclusie is zeer onzeker.

Implicaties van sterke en zwakke aanbevelingen voor verschillende richtlijngebruikers

Sterke aanbeveling

Zwakke (conditionele) aanbeveling

Voor patiënten

De meeste patiënten zouden de aanbevolen interventie of aanpak kiezen en slechts een klein aantal niet.

Een aanzienlijk deel van de patiënten zouden de aanbevolen interventie of aanpak kiezen, maar veel patiënten ook niet. 

Voor behandelaars

De meeste patiënten zouden de aanbevolen interventie of aanpak moeten ontvangen.

Er zijn meerdere geschikte interventies of aanpakken. De patiënt moet worden ondersteund bij de keuze voor de interventie of aanpak die het beste aansluit bij zijn of haar waarden en voorkeuren.

Voor beleidsmakers

De aanbevolen interventie of aanpak kan worden gezien als standaardbeleid.

Beleidsbepaling vereist uitvoerige discussie met betrokkenheid van veel stakeholders. Er is een grotere kans op lokale beleidsverschillen. 

Cluster/richtlijn: Cluster arteriële en veneuze pathologie, richtlijn diepe veneuze ziekte

Uitgangsvraag/modules:   Module 4. Wat zijn de voordelen van embolisatie van bekkenvenen in vergelijking met een conservatieve behandeling (of geen behandeling) bij patiënten met pelvic venous disorder?

Database(s): Embase.com, Ovid/Medline

Datum:  4-4-2024, 10-6-2024

Periode: nvt

Talen: geen restrictie

Literatuurspecialist: Ingeborg van Dusseldorp

Toelichting:

10-6-2024

Er wordt nogmaals kritisch gekeken, waarbij de PICO iets scherper wordt weergegeven en de terminologie iets verandert.

P = patiënten met insufficiënte bekkenvenen

I  = embolisatie

Omdat het totaal aantal referenties boven de 500 komt, worden in eerste instantie de SRs en Clinical trials, RCTs aangeboden

4-4-2024

Voor deze vraag is gezocht met de concepten:

Pelvic venous disorder EN embolisatie

Omdat de limitering vanaf 2000 slechts van toepassing was op een klein aantal referenties, is besloten om geen limitering op tijd toe te passen

Te gebruiken voor richtlijntekst:

In de databases Embase.com en Ovid/Medline is op 10-6-2024 systematisch gezocht naar systematische reviews, clinical trials en RCTs over embolisatie bij patienten met insufficiënte bekkenvenen. De literatuurzoekactie leverde  208 unieke treffers op.
