Guideline requirements. Question: In your opinion, what must a good set of guidelines have for you to consider implementing it? Please indicate how important the following aspects are to you. (N = 3098; response categories Very important/Somewhat important were combined)

		Rotated Component Matrix
	Very important/ Somewhat important (%)	Component 1(Variance Explanation: 56.8%)	Component 2(Variance Explanation: 13.8%)	Component 3 (Variance Explanation: l.: 10.6%)	Component 4 (Variance Explanation: 9.5%)
It should be as easy as possible to implement	90	0.401	0.804	0.277	−0.047
It must be ensured that the recommendations have a sound legal basis	87	0.304	0.904	0.074	0.131
It should provide easily comprehensible algorithms or diagnostic and therapeutic approaches (i.e., using diagrams)	85	0.884	0.302	0.200	−0.086
It must specify red flags, i.e., particularly important warning signs that indicate clinical pictures in need of further clarification	84	0.768	0.531	0.194	−0.030
The benefits of its recommendations for action must be evidence-based and scientifically valid	83	0.909	0.213	0.221	0.074
General practitioners should be involved in the development of guidelines or have tested guidelines in a practice setting before publication	79	0.028	0.447	0.833	0.168
The recommendations for action should conform to the applicable fee schedule to ensure that physician costs are covered	76	0.134	0.882	0.072	0.324
It should provide concrete ranges for laboratory values (e.g., for blood testing)	65	0.757	0.367	0.043	0.454
It should provide clear information on when or for how long a wait-and-see approach is appropriate and when referral is indicated	64	0.752	0.323	0.117	0.476
The guidelines must provide intelligent recommendations for the delegation of tasks for the entire practice team	51	0.292	−0.037	0.880	0.117
It should be an S3 guideline (highest evidence level)	41	−0.016	−0.111	0.736	0.554
Guideline-compliant training courses must be available	39	0.091	0.230	0.240	0.892
