Key result
Although 13 of 15 major hypertension guidelines recommended measuring blood pressure in both arms, only seven provided justification, one cited evidence, and none described the appropriate technique.
Hypertension guidelines frequently recommend dual-arm blood pressure measurement but rarely provide the necessary justification, evidence, or practical techniques to encourage physician adherence.
Answers are grounded in this paper and cite their sources.
Unsupported dual-arm BP recommendations may limit adherence; leaves open rigorous evidence and technique standardization in future guidelines.
For at least 25 years, hypertension guidelines have suggested measuring blood pressure in both arms, but GPs' acceptance of this is low. Current and past versions of major guidelines were identified to review and assess the degree to which they provided justification, evidence, and a description of dual-arm measurement techniques. It is suggested that if guidelines better justified recommendations and cited primary literature to support claims, a greater percentage of practitioners might accept and adhere to such guidance.

Parker et al. (2009) conducted a review in Hypertension (n=15). Dual-arm blood pressure measurement recommendations was evaluated on Proportion of guidelines providing justification, evidence, and technique description for dual-arm measurement. Although 13 of 15 major hypertension guidelines recommended measuring blood pressure in both arms, only seven provided justification, one cited evidence, and none described the appropriate technique.
