Adherence of Clinical Practice Guidelines for Oropharyngeal Dysphagia in Parkinson Disease to Trustworthy Standards: A Systematic Survey.

The search used snowball sampling via personal networks, which may have missed some guidance documents. The identified guidelines were predominantly from North America and Europe, limiting global generalizability. The researchers did not contact guideline authors to verify methodological details, so their assessment may underestimate actual rigor if it was simply not reported. The NEATS tool does not evaluate the clinical appropriateness or effectiveness of the recommendations themselves, only their methodological quality.

The authors of this survey declared no conflicts of interest. The survey assessed guidelines developed by various professional societies, some of which had disclosed funding, but the survey itself was independent.

Do not interpret the lack of specific recommendations as evidence that interventions are ineffective. The guidelines are methodologically weak and vague, not necessarily clinically wrong. Use individualized assessment and current best evidence rather than adhering strictly to these low-quality guidelines.
