Abstract
Introduction
Falls are a major cause of morbidity and mortality in patients over 65. Unrecognised postural hypotension is a significant and treatable contributor. Training nurses and health-care assistants (HCAs) in correct measurement technique can be challenging, as these groups are rarely able to fully attend single sessions due to urgent clinical commitments, night duties and staff-shortages.
We aimed to improve the frequency and quality of lying-standing blood pressure (LSBP) measurement in a Geriatric inpatient cohort.
Methods
3 PDSA cycles were performed over a 10-month period on a single Care of the Elderly ward, including an initial audit in March 2021. The outcome measures were 1. the percentage of non-bedbound patients having LSBP correctly measured (5-min recumbent, 1 and 3 min standing readings), assessed by chart review and 2. the understanding and confidence of measurers in correct technique, as assessed by a questionnaire.
The intervention was developed into three separate days of ad-hoc mobile teaching sessions to allow reinforcement of knowledge. Trainers moved from bay-to-bay delivering a 5-minute pre-prepared presentation/demonstration on the indications and correct technique of LSBP measurement. This was repeated throughout each day until all measurers had participated.
Results
On initial assessment, only 21% (6/28) of non-bedbound patients had LSBP correctly measured. This improved to 44% (8/18) by July and 62% (8/13) by December 2021.
When sampled, measurers had sustained improvements from July (n=8) to December (n=7), in terms of self-rated confidence (mean 4.4/5 vs 4.9/5), correct technique (25% vs 100%), interpretation of results (25% vs 43%) and knowledge of contraindications to measurement (88% vs 100%).
Conclusions
We describe a strategy using ad-hoc mobile teaching sessions to train nurses and HCAs to measure LSBP in a Geriatric inpatient cohort, which resulted in sustained improvements. We believe this technique is readily applicable to other units and areas of practice.
