Blood pressure measurement: assessing staff knowledge

A survey on personnel awareness of the factors affecting accurate blood pressure measurement in the medical centres of Jahrom County

Aims and objectives

The main purpose of this study was to determine the clinical skill of the medical personnel on level of awareness of standard methods used during blood pressure measurement.

Background

Blood pressure measurement is one of the vital clinical proficiencies the hospital personnel must be equipped with. Results from different surveys highlight the importance of awareness amongst medical personnel in controlling blood pressure.

Design

Descriptive cross-sectional study.

Methods

Using standardized questionnaires devised by the researcher, data were collected from 302 participants working in healthcare centres in Jahrom. The extracted data were analysed using SPSS.

Results

Observations showed that 10-20% of the participants had wide knowledge of influential factors affecting blood pressure measurement. Moreover, there was a meaningful relation between holding higher degrees and accurate blood pressure measurement (p < .05). Nevertheless, besides the personnel holding lower degrees, those holding higher educational degrees also had dearth of knowledge of factors affecting blood pressure measurement.

Conclusions

The overall findings of this study indicate that the knowledge among the hospital personnel in determining factors affecting blood pressure measurement was inadequate.

Nurse effects on measurement error in household biosocial surveys

Background

Biosocial survey data are in high demand, yet little is known about the measurement quality of health measures collected by nurses in respondents’ homes. Our objective was to analyze the degree to which nurses influence measurement in anthropometric and physical performance indicators collected from respondents in two nationally-representative UK biosocial surveys.

Methods

The English Longitudinal Survey of Ageing and the UK Household Longitudinal Study – Understanding Society were used to analyze fourteen anthropometric and physical performance measures covering weight, height, pulse, grip strength, and lung capacity. Cross-classified multilevel models were used to estimate “nurse effects” on measurement error.

Results

Overall, there is a medium effect of nurses on measurement. Across all measures collected in both studies, nurses explain around 13% of all measurement variation. Variation in specific measures range between approximately 2 and 25%. Grip strength and lung capacity are more heavily influenced by nurses than are height, weight, and pulse. Lastly, nurse characteristics explain only a very small proportion of nurse measurement variation.

Conclusion

Objective health measures collected by nurses in household biosocial surveys are susceptible to non-trivial amounts of measurement variation. Nurse ID numbers should be regularly included in biosocial data releases to allow researchers to account for this unnecessary source of variation. Further, researchers are advised to conduct sensitivity analyses using control variables that account for nurse variation to confirm whether their substantive findings are influenced by nurse measurement effects.

Blood Pressure Measurement Training Program and Adherence of Public Health Nurses to BP Measurement Guidelines

Objective

To compare the level of adherence of public health nurses to BP measurement guidelines based on their knowledge if the guidelines and skills in BP measurement before and after Blood Pressure Measurement Training Program (BPMTP).

Methods

An experimental pre- and post-test design using two-staged cluster randomization was conducted. 118 PHNs (mean age ± 38.45 years, mean years of experience ± 13.45 years; 84.1% women) from six districts in Manila were equally assigned to either the BPMTP group or control group. Structured instruments were used.

Results

Demographic characteristics, current BP measurement practices, and level of adherence to BP measurement guidelines based on knowledge of the guidelines and skills in BP measurement were equivalent in both groups at baseline. Nurses in the BPMTP group showed improved adherence (p=<0.05) compared to nurses in the control group. Both groups did not show significant change in their skill on recording, interpretation, and referral (p=1.000).

Conclusion

This study showed that Blood Pressure Measurement Training Package is feasible in improving adherence of nurses based on their increased knowledge of the BP measurement guidelines and skills in BP measurement. A larger-scale study is warranted to show that BPMTP can potentially improve clinical management of hypertension in public health clinics globally.

The 2015 Canadian Hypertension Education Program recommendations for blood pressure measurement, diagnosis, assessment of risk, prevention, and treatment of hypertension

The Canadian Hypertension Education Program reviews the hypertension literature annually and provides detailed recommendations regarding hypertension diagnosis, assessment, prevention, and treatment. This report provides the updated evidence-based recommendations for 2015. This year, 4 new recommendations were added and 2 existing recommendations were modified. A revised algorithm for the diagnosis of hypertension is presented. Two major changes are proposed: (1) measurement using validated electronic (oscillometric) upper arm devices is preferred over auscultation for accurate office blood pressure measurement; (2) if the visit 1 mean blood pressure is increased but < 180/110 mm Hg, out-of-office blood pressure measurements using ambulatory blood pressure monitoring (preferably) or home blood pressure monitoring should be performed before visit 2 to rule out white coat hypertension, for which pharmacologic treatment is not recommended. A standardized ambulatory blood pressure monitoring protocol and an update on automated office blood pressure are also presented. Several other recommendations on accurate measurement of blood pressure and criteria for diagnosis of hypertension have been reorganized. Two other new recommendations refer to smoking cessation: (1) tobacco use status should be updated regularly and advice to quit smoking should be provided; and (2) advice in combination with pharmacotherapy for smoking cessation should be offered to all smokers. The following recommendations were modified: (1) renal artery stenosis should be primarily managed medically; and (2) renal artery angioplasty and stenting could be considered for patients with renal artery stenosis and complicated, uncontrolled hypertension. The rationale for these recommendation changes is discussed.

Knowledge of correct blood pressure measurement procedures among medical and nursing students

This study reports on the level of knowledge about correct blood pressure (BP) measurement procedures among 175 third-year and 176 sixth-year students at a medical faculty and 58 third-year students at a nursing college. Only 51.8% of all students thought that they knew how to measure BP correctly (28.6% in the third year and 61.9% in the sixth year at the medical faculty and 91.4% at the nursing college). Among sixth-year medical students, 12.5% knew the appropriate cuff size, 35% that the stethoscope diaphragm should not be placed under the cuff, and 43% that the cuff deflation rate affects BP measurement. Among nursing students, 33% knew the appropriate cuff size, 22% that an outpatient's BP should be measured more than once during each visit, and 55% that a diagnosis of hypertension can only be made if the BP is elevated on more than one visit.

Infection control and management of MRSA: assessing the knowledge of staff in an acute hospital setting

Much of the recent work in tackling meticillin-resistant Staphylococcus aureus (MRSA) has focused on hygiene in hospitals, but it is unclear how much hospital staff know about the treatment and management of patients who are colonized or infected with MRSA. The aim of this study was to assess the knowledge and perceived practice of staff regarding MRSA and its management in an acute hospital setting. A further aim was to determine what staff felt was needed in terms of information or education on the risks, management and treatment of MRSA. A questionnaire survey was carried out through group administration during a study day and by face-to-face interviews. Subjects included in the questionnaire were infection and colonization, treatment, and the availability of local support and advice. There were 174 responses, divided equally between doctors and nurses. Knowledge on many aspects of MRSA and its management was deficient, although the majority of participants who felt that they required additional information about MRSA acknowledged this. The survey confirmed that assumptions should not be made about adequate knowledge and expertise of staff in relation to MRSA. Gaps in awareness of aspects of care and management were highlighted and information and educational needs identified.

The need for nurses to have in service education to provide the best care for clients with chest drains

Chest drains are a widespread intervention for patients admitted to acute respiratory or cardiothoracic surgery care areas. These are either inserted intraoperatively or as part of the conservative management of a respiratory illness or thoracic injury. Anecdotally there appears to be a lack of consensus among nurses on the major principles of chest drain management. Many decisions tend to be based on personal factors rather than sound clinical evidence. This inconsistency of treatment regimes, together with the lack of evidence-based nursing care, creates a general uncertainty regarding the care of patients with chest drains. This study aimed to identify the nurses' levels of knowledge with regard to chest drain management and identify and to ascertain how nurses keep informed about the developments related to the care of patients with chest drains. The data were collected using survey method. The results of the study revealed deficits in knowledge in a selected group of nurses and a paucity of resources. Nurse managers are encouraged to identify educational needs in this area, improve resources and the delivery of in service and web-based education and to encourage nurses to reflect upon their own knowledge deficits through portfolio use and ongoing professional development.

Blood Pressure Measurement Education and Evaluation Program improves measurement accuracy in community-based nurses: A pilot study

PURPOSE

Pilot study was developed to determine if a blood pressure measurement training program would improve guideline knowledge and technique in community-based nurses (n= 6).

METHODS

American Heart Association guidelines were used to develop the Blood Pressure Measurement Education and Evaluation Program (BEEP). Data on guideline knowledge, device quality, measurement technique, terminal digit bias, range of error, and attitude of change were collected prior and after BEEP.

CONCLUSIONS

BEEP development was feasible and acceptable. The device score was 100%. Knowledge improved but not statistically significant (p= 0.64), as did terminal digit bias. Technique prior to BEEP was poor (T= 15) but improved significantly after BEEP (T= 26 on a scale of 32, p= 0.0006). Range of error decreased but was only significant in the diastolic pressure (p= 0.02).

IMPLICATIONS FOR PRACTICE

BEEP is feasible. Baseline blood pressure measurement technique is poor in community-based nurses. Our study suggests that this poor technique can benefit from an educational program and result in improved blood pressure measurement accuracy.

Nurses’ knowledge of chest drain care: an exploratory descriptive survey

Chest drains are a common feature of patients admitted to acute respiratory or cardio-thoracic surgery care areas. Chest drains are either inserted intraoperatively or as part of the conservative management of a respiratory illness or thoracic injury. Anecdotally, there appears to be a lack of consensus among nurses on the major principles of chest drain management. Many decisions tend to be based on personal factors rather than sound clinical evidence. This inconsistency of treatment regimes, together with the lack of evidence-based nursing care, creates a general uncertainty regarding the care of patients with chest drains. This study aimed to identify the nurses' levels of knowledge with regard to chest drain management. The research objective of this study was to describe the nurses' levels of knowledge regarding the care of the patient with chest drains. The data were collected using survey method. The results of the study revealed deficits in knowledge in a select group of nurses. Several service-led options exist with regard to improving knowledge in this area, such as service study days as well as ward-based tutorials. However, in an era of increasing accountability together with the impetus for each nurse to provide evidence-based care, it is crucial for individual nurse responsibility in the pursuit of knowledge in this area. Nurses must be supported by local practice development and through personal portfolio use to identify gaps in knowledge and seek appropriate training and resources.

The importance of accurately assessing orthostatic hypotension

Potential adverse outcomes of orthostatic hypotension (OH) range from mild symptoms of dizziness to more severe consequences of falls, fractures, and immobility. OH can be a significant problem among patients who use psychotropic medications. Clinical practitioners have observed that OH assessment among patients receiving psychotropic medications is often overlooked or inaccurate. This article addresses two areas critical to the development of a clinical standard for measuring orthostatic blood pressure: a review of procedural inconsistencies regarding OH assessment and recommendations for obtaining accurate orthostatic measurements.
