Knowledge, perception and practice of health professionals regarding blood pressure measurement methods: a scoping review.

OBJECTIVE: Guideline-concordant performance of accurate blood pressure measurement (BPM), whether the modality is home (HBPM), ambulatory (ABPM), automated (AOBP) or office (OBPM), is dependent on proper technique. Knowledge, perception and practice of health professionals for BPM is crucial and has been partly studied, but a thorough review has never been reported. A scoping review of global studies was conducted to synthesize published data on this topic. METHODS: An Arksey and O'Malley methodological framework was used. Keywords were identified and extraction was completed to April 2019 using CINAHL and MEDLINE. Studies were classified as positive for knowledge, perception and practice if the majority (>50%) of reported responses were favourable, and negative otherwise. If specific results were not reported, the author's conclusions were used to classified. RESULTS: Seventy-two studies were identified: 25 HBPM, 14 ABPM, two AOBP, 40 OBPM. For knowledge, the percentage of negative studies were higher for HBPM (40%) and OBPM (68%) and lower for ABPM (14%) regarding BPM techniques. For perception, the number of negative studies were lower for HBPM (20%) and ABPM (7%) regarding usefulness of BPM methods in hypertension management. For practice, the number of negative studies were higher for HBPM (48%), ABPM (71%), OBPM (73%) and AOBP (50%) regarding implementation of hypertension guidelines. CONCLUSION: The results of this scoping review demonstrate adequate perception of BPM but suboptimal knowledge and practice. Education is still needed to improve knowledge and practice. Future efforts should focus on improving what we know and what we do when measuring BP.

The feasibility of home self-assessment of vital signs and symptoms: A new key to telehealth for individuals?

OBJECTIVE: During the COVID-19 pandemic, social distancing and self-isolation called for innovative, readily implementable, and effective short-term health solutions. The objective of this study was to assess the feasibility of self-assessment of vital signs and symptoms with electronic transmission of results, by self-isolating individuals with positive SARS-CoV-2 polymerase chain reaction (PCR) test. The secondary objective was to describe the association between the presence of abnormal vital signs and severe symptoms as well as their evolution over time. METHOD: Participants with positive SARS-CoV-2 PCR test were asked to perform twice daily standardized vital signs measurements and self-assessment of symptoms for 14 consecutive days. All data were transmitted electronically through a mobile application and a web-based platform. Participants were provided with decision support tools based on the severity of their condition and a weekly nurse practitioner telephone follow-up. Abnormal values for vital signs and severe symptoms were determined. Per participant and per days, proportions of abnormal vital signs and severe symptoms were calculated. RESULTS: Data from 46 participants (mean age 54.1 ± 6.9 years, 54% male) were available for analysis. On average, participants performed the standardized self-assessment for 12.3 ± 3.4 days (89% performed at least 7 measurement days and 61% completed all 14 days). The highest proportions abnormal values for vital signs were for oximetry (20.1%) and respiratory rate (12.1%). The highest proportions of severe symptoms were for fatigue (16.9%) and myalgia. (10.2%). The combined proportion of abnormal vital signs and severe symptoms was maximal on day 1 with 20.3% of total measurements, with a linear decrease to 3.5% on day 14. CONCLUSION: Remote initiation of home measurements of vital signs and symptoms, self-management of these measures, accompanied by a decision support tool and supported by preplanned nurse follow-up are feasible. This could allow to opening up new insight for the care of sick individuals.

Screening for hypertension in adults during emergency department consultation: a systematic review.

A large proportion of patients affected with hypertension go undetected. A systematic review was conducted to assess the performance of a screening strategy in adults using blood pressure measurement at the time of an emergency department consultation. A systematic literature search on Embase, CINHAL and Medline was carried out. This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Diagnostic Test Accuracy. Intervention studies with adults including at least one blood pressure measurement for all participants were included. A repeat blood pressure assessment had to have been carried out to assess the validity of the elevated blood pressure value within the next few days after the emergency department initial visit. Out of 1030 articles identified, published between 1985 and 2018, 10 articles met the inclusion criteria. There were no randomized clinical trials. Mean age of participants was 51.6 years. A single study reports that blood pressure screening was measured according to hypertension guidelines referred to in the study. The average follow-up rate was 61.9% (95% confidence interval 45.5-78.3). For diagnostic confirmation, four studies used a blood pressure measurement method based on the reported guidelines. Half of the patients (50.2%) with elevated blood pressure during the emergency department visit had blood pressure corresponding to uncontrolled elevated blood pressure at follow-up measurement. The contribution of emergency department to the screening for hypertension, by recognizing the presence of elevated blood pressure and then making a referral for diagnostic confirmation, could provide an opportunity to detect a large number of people with hypertension.

Screening for hypertension: an elevated office blood pressure measurement is valuable, adding an automated one is even better.

BACKGROUND: Previous studies have examined the relevance of hypertension (HTN) screening in walk-in clinics. So far, no valid algorithm has been proposed on how to integrate HTN screening in this context. The aim of our study was to assess, in a walk-in clinic setting, the HTN screening strategy for performing an automated office blood pressure (AOBP) measurement following an initially high office blood pressure (OBP) measurement. PATIENTS AND METHODS: Included participants were adults with nonemergent medical conditions and an initial walk-in clinic OBP between systolic 140 and/or diastolic 90 mmHg and systolic 180 and/or diastolic 110 mmHg. AOBP was performed with patients unattended. The 24-h ambulatory blood pressure measurement (ABPM) was used as the diagnostic threshold. RESULTS: Fifty participants were included in the study. The overall HTN prevalence as confirmed by the 24-h ABPM was 46% [95% confidence interval (CI): 32.19-59.81]. After an elevated OBP, AOBP over diagnostic thresholds occurred in 32 patients and were confirmed by ABPM in 20 participants, leading to a 62.5% positive predictive value (95% CI: 51.5-72.3%). Measurements under the AOBP diagnostic threshold occurred in 18 patients and were confirmed by ABPM in 15 participants, leading to a negative predictive value of 83.3% (95% CI: 62.3-93.8%). CONCLUSION: In a walk-in clinic, an elevated OBP is a useful screening tool due its ability to recognize nearly one in two patients as actually hypertensive. Adding an AOBP makes it possible to specify what course of action to take. This ultimately results in better targeting of patients for an ABPM referral.

Spastic diplegia and other motor disturbances in infants receiving interferon-alpha.

OBJECTIVE: To determine how frequently the use of -interferon (-IFN) is associated with the development of spastic diplegia. STUDY DESIGN AND METHODS: Meta-analysis of 600 English manuscripts published January 1991 to June 2002 reporting -IFN use in infants/children. We identified 3,113 children 18 years of age or younger and an estimated 3,055 children 12 years of age or younger who received -IFN therapy. Sixty-nine percent were treated for chronic hepatitis and 14% for vascular neoplasms. OUTCOME MEASURE: Neurologic examination to confirm spastic diplegia or a motor developmental disturbance other than spastic diplegia such as hyperactive deep tendon reflexes, gait disturbances, or impaired fine motor control. RESULTS: Including our index case, 11 of 441 children with vascular lesions developed spastic diplegia and an additional 16 of 441 developed a motor developmental disturbance. All of these children were less than 1 year of age at initiation of therapy. Mean age of initiation and duration of -IFN therapy were not significantly different between groups (P >.05); however, motor developmental disturbances improved with cessation of therapy, whereas spastic diplegia did not. No child receiving treatment for chronic hepatitis developed neurologic complications; however, only 49 children were less than 1 year of age at initiation of therapy. CONCLUSION: -IFN should not be used in infants under 1 year of age unless life-threatening conditions do not respond to any other form of treatment. If -IFN must be used, children should have monthly neurologic examinations. If a motor developmental disturbance is detected and -IFN therapy can be discontinued, it should be.

An evaluation of epidural analgesia following circumferential belt lipectomy.

BACKGROUND: Belt lipectomy combines traditional abdominoplasty with a circumferential excision of skin and fat, with resultant buttock and lateral thigh lifts. Because of the extensive nature of the procedure, postoperative pain management can be difficult. Epidural analgesia has been shown to be efficacious in treating postoperative pain. This study compares the postoperative use of epidural analgesia with more traditional pain management regimens in a large series of belt lipectomy patients. METHODS: Charts of 62 belt lipectomy patients were examined retrospectively. Postoperative pain control regimen, pain scores, total amount of opioids administered, and side effects encountered were recorded. Twenty-seven patients had traditional pain control regimens, opioids on demand, and pain control pumps. Thirty-five patients received epidural analgesia as their primary mode of postoperative pain control. RESULTS: Pain scores and total nonepidural opioids used were lower in the epidural analgesia group on postoperative days 0 and 1 compared with the nonepidural group. The two groups converged on postoperative days 2 through 5, sharing similar pain scores and opioid use after discontinuation of epidural analgesia. The incidence of side effects was similar in the two groups, with the exception of pruritus, which was much more prominent in the epidural group. Eight of the 35 epidural patients (23 percent) experienced transient and minor complications associated with epidural therapy; several resolved spontaneously, whereas the balance resolved with cessation or modification of the epidural infusion. CONCLUSIONS: Epidural analgesia is more effective than traditional pain control methods in reducing immediate postoperative pain in belt lipectomy patients. On the basis of these findings, epidural analgesia should also be considered for postoperative pain management in other truncal procedures.
