1335 POSTURAL HYPOTENSION QUALITY IMPROVEMENT PROJECT - HOW GOOD WE ARE IN MEASURING IT?

Abstract

Abstract Introduction A large proportion of Morriston Hospital’s acute medical take consists of elderly patients admitted with falls. Postural hypotension is a cause of syncope and fall which contributes to morbidity, disability and death in cases of injury in the frail and elderly population1. Hence, diagnosing and treating postural hypotension is crucial. It is important that the measurement of lying-standing blood pressure (LSBP) is consistent to ensure reliability of results as this would affect patients’ management. The aim of this project is to assess how postural hypotension is diagnosed in various clinical areas and assess the quality of detection. Methods We designed a survey to identify baseline variation in method and accuracy in measuring postural hypotension and compared it against National Audit in-patient Falls RCP “Falls and fragility Fracture Audit Programme”1. The survey was distributed across acute and general clinical areas involving staff nurses, healthcare assistants and junior doctors. We collected and analysed the data, implemented outcomes and re-conducted the second PDSA. Grand Round presentation and worked-based tutorial sessions based on the above was our intervention. Results 57 staff members (acute medical, surgical wards and emergency department) participated. PDSA2 showed improvement of >25% of participants allowing patients to rest before initial BP measurement compared to PDSA1. There is an improvement of approximately 7% in repositioning the patient. 47% measured standing BP between 1-3mins at PDSA1 and this has doubled in PDSA2. Conclusions This study showed the importance in ensuring consistency in measuring LSBP. There was significant variation in timing and measurements which have impacted the results and interpretation of postural hypotension. The education sessions had positive impact and is also a sustainable practice. Reference 1. Falls Prevention in Hospital, 2022.
