Cervicale tractie
Uitgangsvraag
Welke rol heeft cervicale tractie in de behandeling van CRS?
Aanbeveling
Zie af van het verrichten van cervicale tractie bij patiënten met een cervicaal radiculair syndroom gezien de onduidelijke positieve effecten en de mogelijke bijwerkingen na de interventie.
Overwegingen
Voor- en nadelen van de interventie en de kwaliteit van het bewijs
In deze module worden verschillende fysiotherapeutische interventies geëvalueerd als behandeling van patiënten met cervicaal radiculair syndroom (CRS). In totaal zijn er twintig RCTs gevonden die de half harde halskraag, cervicale tractie, oefentherapie, neurodynamische mobilisatie of manuele therapie onderzochten. De bewijskracht voor de cruciale uitkomstmaten ‘disability’, ‘functioneren’, en ‘kwaliteit van leven’ was voor alle interventies zeer laag, behalve voor de interventie oefentherapie. Voor oefentherapie resulteerde de bewijskracht in laag m.b.t. de cruciale uitkomstmaten.
De zeer lage bewijskracht betekent dat andere studies kunnen leiden tot nieuwe inzichten. De studiepopulaties en interventies waren niet altijd goed met elkaar te vergelijken en daarnaast bevatten de studies enkele methodologische beperkingen. Daarom kunnen er op basis van de literatuur geen harde conclusies geformuleerd worden.
Bij patiënten met een CRS is er sprake van bewegend disfunctioneren mede op basis van de aanwezige radiculaire (en soms neuropathische) pijn en andere sensorische en motorische disfuncties vanwege de radiculopathie. Na het verdwijnen van de oorzaak van een CRS, verdwijnen niet altijd alle disfuncties zonder een specifiek daarop gerichte interventie (Hides, 1996). Fysiotherapie kan een aanvulling zijn op het natuurlijk herstelproces bij patiënten met een CRS en, ook ná een eventuele chirurgische interventie, essentieel zijn in het herstellen van ontstane disfuncties zoals spierkrachtverlies. Een fysiotherapeutisch behandelprogramma is altijd multimodaal (Thoomes, 2022).
Waarden en voorkeuren van patiënten (en evt. hun verzorgers)
Het is de mening van de werkgroep dat de beslissing om fysiotherapeutische begeleiding te zoeken vooral aan de patiënt over moet worden gelaten. Als de patiënt besluit zich te laten begeleiden door een fysiotherapeut, is het wel wenselijk dat de behandelend fysiotherapeut ruime ervaring heeft met het behandelen en begeleiden van patiënten met een CRS, om onnodige exacerbaties of bijwerkingen te voorkomen.
De belangrijkste doelen van de fysiotherapeutische interventies zijn afhankelijk van het stadium waar de aandoening zich in bevindt. In de initiële, reactieve fase waarin de reactiviteit van de zenuwwortel nog voorop staat, zal de focus vooral liggen op uitleg en advies hoe de verergering van klachten het best te voorkomen is. Daarbij zijn correct gebruik van effectieve pijnmedicatie (in overleg met de (huis)arts) en wellicht het overwegen van het gebruik van een half harde halskraag in de eerste drie tot maximaal 6 weken (met een bijpassend afbouw beleid) van belang. Self-empowerment van de patiënt is nu ook al van belang. In de subacute fase zal de focus van de interventies verschuiven naar een meer actieve aanpak, rekening houdend met de belastbaarheid van de individuele patiënt. Hierin kunnen de interventies die de werkgroep voorstelt allemaal een rol spelen. In de eindfase van herstel verschuift de focus van de fysiotherapeutische interventies nog meer naar zelfredzaamheid van de patiënt en het geven van de tools waarmee hij/zij zijn eigen belastbaarheid en individuele disfuncties zelf actief verder gestructureerd kan verbeteren.
Kosten (middelenbeslag)
Er is weinig bekend over de kosteneffectiviteit van fysiotherapie bij patiënten met CRS (Alvin, 2014). In 2019 vergeleek één studie chirurgie (ACDF) met conservatief beleid van cervicale epidurale injecties in combinatie met fysiotherapie (Rihn, 2019). Deze analyses suggereerde dat ACDF kosten-effectiever is ($6.768) in vergelijking met cervicale epidurale injecties in combinatie met fysiotherapie (Rihn, 2019). Daarnaast is onderzocht dat het merendeel van de kosten gerelateerd aan CRS, veroorzaakt wordt door het diagnostisch traject (Barton, 2019).
Davidson (2020) rapporteerde de kosten van niet-operatieve therapie voorafgaand aan ACDF-chirurgie in Amerika. De totale directe kosten van alle niet-operatieve therapieën voorafgaand aan ACDF-chirurgie waren $17.255.828 met $1.278 aan fysiotherapie per patiënt als hoogste gemiddelde gefactureerde dollars.
Op basis van kostenanalyses (Barton, 2019; Rihn, 2019; Davidson, 2020) is het dus aannemelijk dat vanuit het oogpunt van kosteneffectiviteit, fysiotherapie aanbevolen kan worden. Daarbij moet opgemerkt worden dat voor sommige subgroepen een andere overweging kan gelden en de beste managementstrategie bij elke patiënt individueel beoordeeld moet worden. Zo kunnen de volgende variabelen geassocieerd zijn met een beter resultaat van de operatie: korte duur van pijn, vrouwelijk geslacht, lage gezondheidskwaliteit, hoge niveaus van angst vanwege nek-/armpijn, lage zelfredzaamheid en een hoge mate van angst vóór de behandeling (Engquist, 2015). In de module ‘Timing chirurgische behandeling’ spreekt de werkgroep zich hier ook nog verder over uit.
Aanvaardbaarheid, haalbaarheid en implementatie
Op het gebied van aanvaardbaarheid, haalbaarheid en implementatie voorziet de werkgroep geen grote uitdagingen. Patiënten met een CRS ervaren klachten van het bewegend functioneren. Fysiotherapeuten zijn de experts in het bewegend (dis)functioneren. Zeker gezien de direct toegankelijke positie in de eerstelijnszorg, zijn zij daarmee bij uitstek geschikt om een belangrijke rol in te spelen in een conservatieve behandelstrategie.
De beschreven interventies in deze module vallen in principe allemaal binnen het beroepscompetentieprofiel van de fysiotherapie (KNGF, 2021). Echter worden niet alle interventies in het basis curriculum van de algemeen fysiotherapeut gedoceerd. Onder andere de manipulaties en de neurodynamische mobilisaties maken deel uit van de specialisatie opleiding tot manueel therapeut. Zo worden manueel therapeuten opgeleid tot het behandelen van complexe problemen van het bewegen (dis)functioneren (KNGF, 2021; NVMT, 2023). De werkgroep adviseert daarom om bij het inzetten van een conservatief beleid, patiënten ter overweging mee te geven een manueel therapeut te consulteren.
Hoewel fysiotherapeuten direct toegankelijk zijn, wordt de bekostiging voor een groot deel vanuit de Aanvullende Verzekering (AV) vergoed. Slechts een beperkt deel van de zogenaamde “chronische aandoeningen” (de zgn. lijst Borst of Bijlage 1. van het Besluit zorgverzekering) wordt vanuit de Basisverzekering vergoed. Niet iedereen in Nederland heeft een AV zodat, dus vanuit financieel oogpunt bekeken hebben niet alle patiënten vergelijkbare toegang heeft tot fysiotherapie. Dit kan een mogelijke barrière zijn voor patiënten.
Rationale van de aanbeveling: weging van argumenten voor en tegen de interventie
De bewijskracht voor de uitkomsten pijn, beperkingen, functie en psycho-sociale uitkomsten op basis van beschikbare literatuur is zeer laag. Ofwel, het is onduidelijk is of cervicale tractie een gunstig effect heeft bij patiënten met CRS. Gezien de biomechanische implausibiliteit van de interventie, het vóórkomen van bijwerkingen na de interventie, in combinatie met de uitkomst van een systematische review (Colombo, 2020) is het de mening van de werkgroep dat cervicale tractie niet aanbevolen dient te worden bij patiënten met CRS.
Onderbouwing
Achtergrond
Er is grote variatie in de afwachtende, niet-chirurgische aanpak bij patiënten met een cervicaal radiculair syndroom, momenteel is onduidelijk welke rol fysiotherapie heeft in de behandeling van patiënten met een CRS. Het natuurlijk beloop van een CRS is meestal gunstig (Wong, 2014). Door fysiotherapie wordt gepoogd het natuurlijke beloop van een CRS te bespoedigen. Doel van de fysiotherapeutische behandeling is het verminderen van klachten en (daarmee) het terugkeren in de activiteiten van het dagelijks leven. In deze module worden verschillende, in recente wetenschappelijke literatuur voorgestelde, fysiotherapeutische interventies geëvalueerd.
Conclusies
2a. Cervical traction: Pain (critical)
Very low GRADE |
The evidence is uncertain about cervical traction decreasing pain in patients with cervical radiculopathy, and this effect tends to diminish when additional treatment approaches (such as manual therapy or exercise) are adopted. The evidence is very uncertain whether mechanical traction is preferential over manual traction.

Samenvatting literatuur
2. Cervical traction
Description of studies for treatment with cervical traction
Five RCTs reported on outcomes after treatment with cervical traction for patients with cervical radiculopathy.
Bukhari (2016) aimed to determine the effects of mechanical and manual traction, when performed in addition to manual therapy and home exercises. Patients were randomized into a group receiving a single session of mechanical traction (n =15), applied for 10 minutes with a 10 second pull and 5 seconds rest, with 10% of body weight, or into a group receiving a single session of manual traction (n = 21), applied 10 times with a 10 second pull and 5 seconds rest. Both groups received manual therapy through segmental mobilization after the cervical traction. Patients in both groups were advised to do a home exercise program with active range of motion, stretching, and isometric strengthening exercises, 3 days a week for 6 weeks. Pain on a NRS and disability (NDI, from 0 to 50) were assessed after 6 weeks.
In Fritz (2014)’s RCT, the effectiveness of cervical traction in addition to exercises was examined. Patients were randomized into a group receiving either mechanical traction (n = 31), over-the-door traction (n = 27) or a control group receiving physiotherapy sessions (n = 28). Patients in all three groups received 10 individual physiotherapy sessions over 4 weeks, plus an active exercise program to be performed daily on the days between therapy session. Mechanical traction was performed intermittently with 60 seconds pull and 20 seconds relaxation, for 15 minutes during the individual therapy sessions, whereas continuous over-the-door traction was administered with a device for 15 minutes at home, daily on days of no physical therapy sessions. Outcome measures assessed were disability (NDI) and pain, after 4 weeks, 6 months, and 12 months.
Moustafa (2014) investigated the immediate and long-term effects of a multimodal program with the addition of two different traction approaches. All included patients received a multimodal program with pain relief methods (consisting of infrared radiation for 15 minutes, interferential therapy for 20 minutes at 100 Hz and massage); muscle strengthening exercises twice daily, which increase in duration or resistance during the treatment; and thoracic spine manipulation through thrust techniques. The control group (n = 72) received this multimodal treatment only. The ventroflexion traction group (n = 72) received in addition to the multimodal treatment intermittent traction with increasing force, and an on/off cycle of 50/10 for 20 minutes. The H-reflex based traction group (n = 72) received a similar traction protocol as the ventroflexion traction group, only with a different head posture. All interventions were performed 3 times a week for 4 weeks. Disability (NDI, scoring from 0 to 50) and pain (NRS) were assessed after 4 weeks and 12 months.
The study of Ojoawo (2018) compared the effects of cervical traction and transverse oscillatory pressure to a control group in patients with cervical radiculopathy. The control group (n = 25) received active exercises, ice packs to the cervical region for 7 minutes, and massage. A second group (n = 25) received in addition to control treatment over-the-door cervical traction with a water bath loaded to 10% of the patient’s body weight, for 15 minutes. To the last group (n = 25), transverse oscillatory pressure (TOP) was administered by the therapist manually, on the side of the pain, for 3 times 20 seconds, with 2 minutes of rest in between. They also received the treatment of the control group. All interventions were given twice a week for 6 weeks, after which pain (VAS) and disability (NDI) were assessed.
The study of Young (2009) examined the effects of manual therapy and exercise, with or without the addition of cervical traction. Consecutive patients with unilateral upper-extremity pain were randomized into a mechanical traction group (n = 45), which received intermittent traction for 15 minutes (increasing traction force per visit) with an on/off cycle of 50/10, and the cervical spine at 15 degrees flexion angle, or a sham traction group (n = 36) with equal traction protocol, yet with a maximum of 2.3 kg applied force. Both groups received sessions including: postural education; manual therapy of the upper and mid-thoracic spine through thrust- or non-thrust manipulation, after which they received non-thrust manipulation of the cervical spine (30 seconds or 15-20 repetitions); isometric and strengthening exercises of neck and shoulders. These sessions were on average 2 times per week for 4.2 weeks. In addition, patients in both groups received a home exercise program. The outcome assessment was at 4 weeks. Pain (NRS), disability (NDI, scoring from 0 to 50), function (Patient-Specific Functional Scale, PSFS) and psychosocial outcomes were measured.

Active comparison (C2):
|
As the focus of the research question lies on cervical traction, patients receiving different types of mechanical traction in the studies of Fritz (2014) and Moustafa (2014) have been analyzed as one intervention group.
2a. Pain
All authors reporting on cervical traction, reported on the outcome of pain, after 4 weeks (Bukhari 2016, Ojoawo 2018) or 6 weeks (Fritz 2014, Moustafa 2014, Young 2009). All scores on VAS were converted to values on a 0 to 10 scale, to enable comparison between studies. The results from the studies are presented in Figure 2a. For the traction-group of Ojoawo (2018), the population is divided by the number of comparisons in which it was used (divided over comparison 2.1.1. and 2.1.3.).
Figure 2a. Studies comparing treatment with cervical traction to standard treatment or sham traction (C1); or manual therapy, exercise, or manual traction (C2), for the outcome pain.
For the passive control groups (C1; comparisons 2.1.1 and 2.1.2 from figure 2a), a pooled result in mean difference of -0.70 [95% CI -2.08 to 0.68] is found. For the active control groups (C2, comparisons 2.1.3, 2.1.4 and 2.1.5), a pooled mean difference in pain score of
-0.64 [95%CI -1.23 to -0.05] is calculated. Despite the latter being significant, both numbers are not clinically relevant and need to be interpreted with caution, due to the large methodological and statistical heterogeneity (I2 = 73% and I2 = 76%, respectively).
2b. Disability
All studies reported on disability through the NDI. Scores that have been reported on a 0 to 50 scale have been multiplied by 2 (Buhari 2016; Moustafa 2014; Young 2009), to ensure comparison with scores from 0 to 100. The results from the studies are presented in Figure 2b.
A pooled result in mean difference of NDI for passive comparison C1 of 0.46 [95% CI –-7.25 to 8.18] is found (Figure 2b; 2.2.1 and 2.2.2), and for active comparison C2 (Figure 2b; 2.2.3, 2.2.4, 2.2.5) a value of -6.18 [95% CI -20.53 to 8.17]. For this last comparison, large methodological and statistical heterogeneity are present (I2 = 98%), with the study from Moustafa (2014) only including patients with proven discogenic complaints (possibly explaining the deviating result found in this study).
Figure 2b. Studies comparing treatment with cervical traction to standard treatment or sham traction (C1); or manual therapy, exercise, or manual traction (C2), for the outcome disability.
Results on the outcome disability are presented by Young (2009), on the PSFS as well, using a scale from 0 to 10 (higher scores representing higher function). After 4 weeks of treatment, the traction group had a mean score of 7.0 (SD 3.8), whereas the sham-traction group scored 6.7 (SD 4.3); resulting in a mean difference of 0.29 [95%CI -1.8 to 1.2]. This difference is not statistically significant, nor clinically relevant.
2c. Function, 2d. Quality of life, 2e. Return to work, 2f. Drug consumption
The outcomes quality of life, return to work, and drug consumption were not reported in the studies.
2g. Psychosocial outcomes
Young (2009) reported on psychosocial outcomes in both treatment groups by using the FABQ, on the physical activity and work subscale. A mean difference of -1.8 [95%CI -6.6 to 3.0] was found on the physical activity subscale in favour of traction compared to sham-traction, as higher scores denote higher levels of fear-avoidance. A mean difference of 2.9 [95% -8.1 to 13.9] was found on the work subscale (indicating that sham traction renders better results). Results of both comparisons were not statistically different, nor clinically relevant.
2h. Adverse effects
For 76 patients (88.4%), Fritz (2014) had adverse-reaction data available. A total of 43 patients (56.6%) reported at least 1 reaction perceived as treatment related; most commonly neck pain (42.1%), arm pain (25.0%) and stiffness (19.7%). Of all these reported adverse reactions, 5.6% was rated as severe. The authors report no differences among treatment groups in number, type, duration or severity of adverse reactions.
Level of evidence of the literature
2. Cervical traction
2a. Cervical traction: Pain (critical)
The level of evidence regarding the outcome measure pain was downgraded by 3 levels to very low because of possible selective outcome reporting and selection bias (-1, risk of bias); conflicting results (-1, inconsistency); and a low number of included patients with the interval of the pooled estimate crossing the border of clinical relevance (-1, imprecision).
2b. Cervical traction: Disability (critical)
The level of evidence regarding the outcome measure disability was downgraded by 3 levels to very low because of possible selective outcome reporting and selection bias (-1, risk of bias); conflicting results (-1, inconsistency); a low number of included patients with the pooled estimate crossing the border of clinical relevance and clinical difference (-1, imprecision).
2d. Cervical traction: Quality of life (critical); 2e. Cervical traction: Return to work (important); 2f. Cervical traction: Drug consumption (important)
The outcomes quality of life, return to work, and drug consumption were not reported and could not be graded.
2g. Cervical traction: Psychosocial outcomes (important)
The level of evidence regarding the outcome measure psychosocial outcomes was downgraded by 3 levels to very low because of possible selection bias and possible selective outcome reporting (-1, risk of bias); and a low number of included patients with the interval of the estimate crossing a border of clinical relevance (-2, imprecision).
2h. Cervical traction: Adverse effects (important)
The level of evidence regarding the outcome measure adverse effects was downgraded by 3 levels to very low because of large loss of follow-up and possible selective outcome reporting (-1, risk of bias); and the inclusion of a single study with a low number of included patients (-2, imprecision).
Zoeken en selecteren
A systematic review of the literature was performed to answer the following question:
What is the effect of physiotherapy compared to watchful waiting and/or other forms of physiotherapy in patients with cervical radiculopathy?
P: | Patients with cervical radiculopathy |
I: | Physiotherapy |
C: |
C1. Usual care/ watchful waiting/ placebo or sham (passive control) C2. Other forms of physiotherapy (active control) |
O: | Pain, disability, function, quality of life, return to work, psychosocial outcomes, drug consumption, adverse effects |
Relevant outcome measures
The guideline development group considered pain, disability, function, and quality of life as a critical outcome measure for decision making; and return to work, drug consumption, psychosocial outcomes, and adverse effects as an important outcome measure for decision making.
The working group did not define the outcome measures listed above a priori, but used the definitions used in the described study.
The working group defined a 10% difference for continuous outcome measures (weighted mean difference), 10% for dichotomous outcome measures informing on relative risk (0.91 ≤ RR ≥ 1.1), and standardized mean difference (SMD=0,2 (small); SMD=0,5 (medium); SMD=0,8 (large). This decision was based on the minimal important change scores described in the article by Ostelo (2008), in accordance with the Dutch Lumbosacral Radicular syndrome guideline (2020).
Search and select (Methods)
The databases Medline (via OVID) and Embase (via Embase.com) were searched with relevant search terms from January 1st, 2000 until April 25th, 2022. The detailed search strategy is depicted under the Methods tab. The systematic literature search resulted in 339 hits. Studies were selected based on the following criteria:
- Systematic review and/or meta-analysis, with detailed search strategy, risk of bias assessment, and results of individual studies available; or randomized controlled trial (RCT);
- Patients aged ≥ 18 years;
- studies including ≥ 30 (15 in each study arm) patients;
- studies according to the PICO. Any type of physiotherapy performed in the Netherlands as an intervention, and described placebo/ sham, usual care, no treatment, or other forms of physiotherapy performed in the Netherlands as a comparison; and
- full-text English or Dutch language publication.
A total of 57 studies were initially selected based on title and abstract screening. After reading the full text 37 studies were excluded (see the Table with reasons for exclusion under the Methods tab), and 20 studies were included.
Results
Twenty RCTs were included in the analysis of the literature. Important study characteristics and results are summarized in the evidence tables. The assessment of the risk of bias is summarized in the risk of bias tables. The results are analysed for five different intervention types, in line with the formulated sub questions:
- cervical collar
- cervical traction
- exercise
- neurodynamic mobilisation
- manual therapy
Table 1 gives a summary of the different measures or instruments used for the assessment of analysed outcomes.

1. Studies reporting on the use of a collar |
|||||||
Aksoy, 2018 |
Probably yes
Reason: use of a computer-generated randomization Table, yet randomization process not described. |
Probably no
Reason: no allocation process described. |
Probably no
Reason: Patients, care provider not blinded. Outcome assessor was blinded, yet blinding of data analysts not reported. |
Probably no
Reason: Loss to follow-up was infrequent (max. 10%) in intervention and control group. However, no imputation methods were used. |
Unclear
Reason: No protocol available or previously published. |
Probably no

Probably no
Reason: Patients, physiotherapists and investigators not blinded (blinding of data analysts not reported) |
Probably no
Reason: Loss to follow-up was infrequent in intervention and control group. Inadequate imputation methods were used (last observation carried forward). Sample size not reached, possibly underpowered. |
Definitely no
Reason: secondary outcomes in protocol included time to work, persistent symptoms and surgery; in study report these are sick leave, satisfaction, and use of analgesics |

Inbreng patiëntenperspectief
Er werd aandacht besteed aan het patiëntenperspectief door een afgevaardigde van de Nederlandse Vereniging van Rugpatiënten ‘de Wervelkolom’ te betrekken in de werkgroep. De verkregen input is meegenomen bij het opstellen van de uitgangsvragen, de keuze voor de uitkomstmaten en bij het opstellen van de overwegingen (zie kop ‘Waarden en voorkeuren van patiënten’). De conceptrichtlijn is tevens voor commentaar voorgelegd aan de Nederlandse Vereniging van Rugpatiënten ‘de Wervelkolom’ en de eventueel aangeleverde commentaren zijn bekeken en verwerkt.
Kwalitatieve raming van mogelijke financiële gevolgen in het kader van de Wkkgz
Bij de richtlijn is conform de Wet kwaliteit, klachten en geschillen zorg (Wkkgz) een kwalitatieve raming uitgevoerd of de aanbevelingen mogelijk leiden tot substantiële financiële gevolgen. Bij het uitvoeren van deze beoordeling zijn richtlijnmodules op verschillende domeinen getoetst (zie het stroomschema op de Richtlijnendatabase).
Uit de kwalitatieve raming blijkt dat er waarschijnlijk geen substantiële financiële gevolgen zijn, zie onderstaande tabel.
Module |
Uitkomst raming |
Toelichting |
Fysiotherapie (5 deelmodules) |
Geen financiële gevolgen |
Hoewel uit de toetsing volgt dat de aanbeveling(en) breed toepasbaar zijn (5.000-40.000 patiënten), volgt ook uit de toetsing dat het overgrote deel (±90%) van de zorgaanbieders en zorgverleners al aan de norm voldoet en het geen nieuwe manier van zorgverlening of andere organisatie van zorgverlening betreft. Er worden daarom geen financiële gevolgen verwacht. |
Werkwijze
AGREE
Deze richtlijnmodule is opgesteld conform de eisen vermeld in het rapport Medisch Specialistische Richtlijnen 2.0 van de adviescommissie Richtlijnen van de Raad Kwaliteit. Dit rapport is gebaseerd op het AGREE II instrument (Appraisal of Guidelines for Research & Evaluation II; Brouwers, 2010).
Knelpuntenanalyse en uitgangsvragen
Tijdens de voorbereidende fase inventariseerde de werkgroep de knelpunten in de zorg voor patiënten met CRS. Tevens zijn er knelpunten aangedragen door Ergotherapie Nederland, het Nederlands Huisartsen Genootschap, Nederlandse Vereniging van Ziekenhuizen, Nederlandse Vereniging van Revalidatieartsen, Vereniging van Oefentherapeuten Cesar en Mensendieck, Zorginstituut Nederland, Zelfstandige Klinieken Nederland, via enquête. Op basis van de uitkomsten van de knelpuntenanalyse zijn door de werkgroep concept-uitgangsvragen opgesteld en definitief vastgesteld.
Uitkomstmaten
Na het opstellen van de zoekvraag behorende bij de uitgangsvraag inventariseerde de werkgroep welke uitkomstmaten voor de patiënt relevant zijn, waarbij zowel naar gewenste als ongewenste effecten werd gekeken. Hierbij werd een maximum van acht uitkomstmaten gehanteerd. De werkgroep waardeerde deze uitkomstmaten volgens hun relatieve belang bij de besluitvorming rondom aanbevelingen, als cruciaal (kritiek voor de besluitvorming), belangrijk (maar niet cruciaal) en onbelangrijk. Tevens definieerde de werkgroep tenminste voor de cruciale uitkomstmaten welke verschillen zij klinisch (patiënt) relevant vonden.
Methode literatuursamenvatting
Een uitgebreide beschrijving van de strategie voor zoeken en selecteren van literatuur is te vinden onder ‘Zoeken en selecteren’ onder Onderbouwing. Indien mogelijk werd de data uit verschillende studies gepoold in een random-effects model. Review Manager 5.4 werd gebruikt voor de statistische analyses. De beoordeling van de kracht van het wetenschappelijke bewijs wordt hieronder toegelicht.
Beoordelen van de kracht van het wetenschappelijke bewijs
De kracht van het wetenschappelijke bewijs werd bepaald volgens de GRADE-methode. GRADE staat voor ‘Grading Recommendations Assessment, Development and Evaluation’ (zie http://www.gradeworkinggroup.org/). De basisprincipes van de GRADE-methodiek zijn: het benoemen en prioriteren van de klinisch (patiënt) relevante uitkomstmaten, een systematische review per uitkomstmaat, en een beoordeling van de bewijskracht per uitkomstmaat op basis van de acht GRADE-domeinen (domeinen voor downgraden: risk of bias, inconsistentie, indirectheid, imprecisie, en publicatiebias; domeinen voor upgraden: dosis-effect relatie, groot effect, en residuele plausibele confounding).
GRADE onderscheidt vier gradaties voor de kwaliteit van het wetenschappelijk bewijs: hoog, redelijk, laag en zeer laag. Deze gradaties verwijzen naar de mate van zekerheid die er bestaat over de literatuurconclusie, in het bijzonder de mate van zekerheid dat de literatuurconclusie de aanbeveling adequaat ondersteunt (Schünemann, 2013; Hultcrantz, 2017).

Bij het beoordelen (graderen) van de kracht van het wetenschappelijk bewijs in richtlijnen volgens de GRADE-methodiek spelen grenzen voor klinische besluitvorming een belangrijke rol (Hultcrantz, 2017). Dit zijn de grenzen die bij overschrijding aanleiding zouden geven tot een aanpassing van de aanbeveling. Om de grenzen voor klinische besluitvorming te bepalen moeten alle relevante uitkomstmaten en overwegingen worden meegewogen. De grenzen voor klinische besluitvorming zijn daarmee niet één op één vergelijkbaar met het minimaal klinisch relevant verschil (Minimal Clinically Important Difference, MCID). Met name in situaties waarin een interventie geen belangrijke nadelen heeft en de kosten relatief laag zijn, kan de grens voor klinische besluitvorming met betrekking tot de effectiviteit van de interventie bij een lagere waarde (dichter bij het nuleffect) liggen dan de MCID (Hultcrantz, 2017).
Overwegingen (van bewijs naar aanbeveling)
Om te komen tot een aanbeveling zijn naast (de kwaliteit van) het wetenschappelijke bewijs ook andere aspecten belangrijk en worden meegewogen, zoals aanvullende argumenten uit bijvoorbeeld de biomechanica of fysiologie, waarden en voorkeuren van patiënten, kosten (middelenbeslag), aanvaardbaarheid, haalbaarheid en implementatie. Deze aspecten zijn systematisch vermeld en beoordeeld (gewogen) onder het kopje ‘Overwegingen’ en kunnen (mede) gebaseerd zijn op expert opinion. Hierbij is gebruik gemaakt van een gestructureerd format gebaseerd op het evidence-to-decision framework van de internationale GRADE Working Group (Alonso-Coello, 2016a; Alonso-Coello 2016b). Dit evidence-to-decision framework is een integraal onderdeel van de GRADE methodiek.
Formuleren van aanbevelingen
De aanbevelingen geven antwoord op de uitgangsvraag en zijn gebaseerd op het beschikbare wetenschappelijke bewijs en de belangrijkste overwegingen, en een weging van de gunstige en ongunstige effecten van de relevante interventies. De kracht van het wetenschappelijk bewijs en het gewicht dat door de werkgroep wordt toegekend aan de overwegingen, bepalen samen de sterkte van de aanbeveling. Conform de GRADE-methodiek sluit een lage bewijskracht van conclusies in de systematische literatuuranalyse een sterke aanbeveling niet a priori uit, en zijn bij een hoge bewijskracht ook zwakke aanbevelingen mogelijk (Agoritsas, 2017; Neumann, 2016). De sterkte van de aanbeveling wordt altijd bepaald door weging van alle relevante argumenten tezamen. De werkgroep heeft bij elke aanbeveling opgenomen hoe zij tot de richting en sterkte van de aanbeveling zijn gekomen.
In de GRADE-methodiek wordt onderscheid gemaakt tussen sterke en zwakke (of conditionele) aanbevelingen. De sterkte van een aanbeveling verwijst naar de mate van zekerheid dat de voordelen van de interventie opwegen tegen de nadelen (of vice versa), gezien over het hele spectrum van patiënten waarvoor de aanbeveling is bedoeld. De sterkte van een aanbeveling heeft duidelijke implicaties voor patiënten, behandelaars en beleidsmakers (zie onderstaande tabel). Een aanbeveling is geen dictaat, zelfs een sterke aanbeveling gebaseerd op bewijs van hoge kwaliteit (GRADE gradering HOOG) zal niet altijd van toepassing zijn, onder alle mogelijke omstandigheden en voor elke individuele patiënt.
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. |
Organisatie van zorg
In de knelpuntenanalyse en bij de ontwikkeling van de richtlijnmodule is expliciet aandacht geweest voor de organisatie van zorg: alle aspecten die randvoorwaardelijk zijn voor het verlenen van zorg (zoals coördinatie, communicatie, (financiële) middelen, mankracht en infrastructuur). Randvoorwaarden die relevant zijn voor het beantwoorden van deze specifieke uitgangsvraag zijn genoemd bij de overwegingen. Meer algemene, overkoepelende, of bijkomende aspecten van de organisatie van zorg worden behandeld in de module Organisatie van zorg.
Commentaar- en autorisatiefase
De conceptrichtlijnmodule werd aan de betrokken (wetenschappelijke) verenigingen en (patiënt) organisaties voorgelegd ter commentaar. De commentaren werden verzameld en besproken met de werkgroep. Naar aanleiding van de commentaren werd de conceptrichtlijnmodule aangepast en definitief vastgesteld door de werkgroep. De definitieve richtlijnmodule werd aan de deelnemende (wetenschappelijke) verenigingen en (patiënt) organisaties voorgelegd voor autorisatie en door hen geautoriseerd dan wel geaccordeerd.
