Sources of inaccuracy in the measurement of adult patients' resting blood pressure in clinical settings: a systematic review.

摘要: Background: To interpret blood pressure (BP) data appropriately, healthcare providers need to be knowledgeable of the factors that can potentially impact accuracy BP measurement and contribute variability between measurements. Methods: A systematic review studies quantifying inaccuracy. Medline CINAHL databases were searched for empirical articles reviews published up June 2015. Empirical included if they reported a study was relevant adult patients' resting at upper arm in clinical setting (e.g. ward or office); identified specific source inaccuracy; quantified its effect. Reference lists additional articles. Results: total 328 included. They investigated 29 potential sources inaccuracy, categorized as relating patient, device, procedure observer. Significant directional effects found 27; however, some, inconsistent direction. Compared with true BP, significant individual ranged from -23.6 R33 mmHg SBP - 14 R23 DBP. Conclusion: single value outside expected range should interpreted caution not taken definitive indicator deterioration. Where is abnormally high low, further measurements averaged. Wherever possible, values recorded graphically within ranges. This may reduce inaccuracy scope misinterpretations based on small, likely erroneous misleading, changes.
