Suspicious Index in Lyme Carditis - pre-test probability in a patient with new high-degree AV block.
The SILC Score (Lyme Carditis) is a infectious scoring tool used in paediatric practice. Suspicious Index in Lyme Carditis - pre-test probability in a patient with new high-degree AV block. It scores 5 criteria and interprets the total across 3 bands, so the number always arrives with the severity it implies rather than on its own. In PediAid each criterion is shown as a labelled option with the weight it carries, so the total can be checked rather than taken on trust.
5. They are Constitutional symptoms (fever, malaise, arthralgia, dyspnoea); Erythema migrans rash; Outdoor activity or residence in an endemic area; Male sex; Age < 50 years.
The total is interpreted as: any score - Low probability: score 0-2 - low probability of Lyme carditis. Investigate other causes of AV block; a permanent pacemaker may be appropriate; 3 points or more - Intermediate: score 3-6 - intermediate probability. Send Lyme serology and consider empirical antibiotics before committing to a permanent pacemaker; 7 points or more - High probability: score ≥7 - high probability of Lyme carditis. Treat with antibiotics; AV block is usually reversible, so avoid a permanent pacemaker until treated.
No. It is a structured way to record and communicate severity. A clinician concerned about a child should act on that concern regardless of the total.
Purpose is to avoid unnecessary permanent pacemakers - Lyme-related AV block usually resolves with antibiotic therapy.
Yes. Score definitions are bundled with the PediAid app, so the score computes without a connection.
