From office tools to community supports: The need for infrastructure to address the social determinants of health in paediatric practice.

Previous research has highlighted the importance of addressing the social determinants of health to improve child health outcomes. However, significant barriers exist that limit the paediatrician's ability to properly address these issues. Barriers include a lack of clinical time, resources, training and education with regard to the social determinants of health; awareness of community resources; and case-management capacity. General practice recommendations to help the health care provider link patients to the community are insufficient. The objective of the current article was to present options for improving the link between the office and the community, using screening questions incorporating physician-based tools that link community resources. Simple interventions, such as routine referral to early-year centres and selected referral to public health home-visiting programs, may help to address populations with the greatest needs.

Des recherches antérieures ont fait ressortir l'importance de tenir compte des déterminants sociaux de la santé pour améliorer la santé des enfants. Cependant, des obstacles importants empêchent les pédiatres de bien se pencher sur la question, incluant le manque de temps clinique, de ressources, de formation et d'enseignement sur les déterminants de la santé, la connaissance des ressources communautaires et la capacité de gestion des cas. Les recommandations faites en pratique générale pour aider le dispensateur de soins à orienter les patients vers des ressources communautaires ne suffisent pas. Le présent article vise à présenter des moyens de faire de meilleurs liens entre le cabinet et la communauté, à l'aide de questions de dépistage intégrant des outils médicaux qui dirigent les patients vers des ressources communautaires. Des interventions simples, telles que l'orientation systématique vers des centres de la petite enfance et l'orientation sélective vers des programmes de visite à domicile par la santé publique, peuvent contribuer à servir les populations qui ont les besoins les plus criants.

Evaluation of Intracardiac Pressures Using Subharmonic-aided Pressure Estimation with Sonazoid Microbubbles.

Purpose To investigate if the right ventricular (RV) systolic and left ventricular (LV) diastolic pressures can be obtained noninvasively using the subharmonic-aided pressure estimation (SHAPE) technique with Sonazoid microbubbles. Materials and Methods Individuals scheduled for a left and/or right heart catheterization were prospectively enrolled in this institutional review board-approved clinical trial from 2017 to 2020. A standard-of-care catheterization procedure was performed by advancing fluid-filled pressure catheters into the LV and aorta (n = 25) or RV (n = 22), and solid-state high-fidelity pressure catheters into the LV and aorta in a subset of participants (n = 18). Study participants received an infusion of Sonazoid microbubbles (GE HealthCare), and SHAPE data were acquired using a validated interface developed on a SonixTablet (BK Medical) US scanner, synchronously with the pressure catheter data. A conversion factor, derived using cuff-based pressure measurements with a SphygmoCor XCEL PWA (ATCOR) and subharmonic signal from the aorta, was used to convert the subharmonic signal into pressure values. Errors between the pressure measurements obtained using the SHAPE technique and pressure catheter were compared. Results The mean errors in pressure measurements obtained with the SHAPE technique relative to those of the fluid-filled pressure catheter were 1.6 mm Hg ± 1.5 [SD] (P = .85), 8.4 mm Hg ± 6.2 (P = .04), and 7.4 mm Hg ± 5.7 (P = .09) for RV systolic, LV minimum diastolic, and LV end-diastolic pressures, respectively. Relative to the measurements with the solid-state high-fidelity pressure catheter, the mean errors in LV minimum diastolic and LV end-diastolic pressures were 7.2 mm Hg ± 4.5 and 6.8 mm Hg ± 3.3 (P ≥ .44), respectively. Conclusion These results indicate that SHAPE with Sonazoid may have the potential to provide clinically relevant RV systolic and LV diastolic pressures.

The Effect of Aromatherapy in the Management of Cancer-Related Pain at the End of Life: A Pilot Study.

BACKGROUND: The use of clinical aromatherapy for managing pain has been studied in surgical patients and in women during childbirth. However, there are limited data on the use of aromatherapy for alleviating cancer-related pain, particularly at the end of life. OBJECTIVES: This pilot study identifies the pre- and postimplementation effects of aromatherapy on pain level, pain perception, and the use of oral morphine equivalent among patients with cancer at the end of life. METHODS: A survey was conducted to assess participant pain levels preimplementation of aromatherapy. Participants were then asked to rate their pain and describe how they felt 15 minutes postimplementation of aromatherapy. A chart review comparing oral morphine equivalent use pre- and postimplementation of aromatherapy was also performed. FINDINGS: Postimplementation of aromatherapy, mean pain scores and 24-hour oral morphine equivalent use decreased. Participants also described an improved pain experience and found aromatherapy to be soothing.

Greater number of weekly stairs climbed is associated with lower low back pain prevalence among female but not male physical therapists.

INTRODUCTION: Certain cardiovascular health benefits of stair climbing are now widely accepted, but no prior studies have as yet been found linking the quantity of stairs climbed to low back pain (LBP) morbidity. Low back pain is a common musculoskeletal impairment, and research has begun to show an association between LBP and gluteus maximus (GM) weakness. With stair climbing being the activity which most activates GM, the aim of the present research was to assess the relationship between stair ambulation and LBP prevalence. The hypothesis of this cross-sectional study was that individuals with LBP would report a significantly lower numbers of stair flights climbed compared with individuals without LBP. METHODS: A survey tool was developed and distributed via email to a convenience sample of orthopedic physical therapists. Survey items included information regarding medical history, physical activity, workplace, and LBP factors, using a one-year prevalence period. RESULTS: A total of 363 respondents took the survey and, after application of exclusion criteria, 248 records remained in our final sample. When analyzing all genders together, non LBP (NLBP) respondents reported a mean of 51.62 flights climbed per week; and LBP respondents reported 37.82 flights climbed per week, with P = 0.077. When males and females were analyzed separately, a statistically significant difference in mean number of flights of stairs climbed was found among female respondents (61.51 flights climbed for NLBP and 35.61 flights climbed for LBP females; P = 0.031). When analyzed based on chronicity of LBP, an even stronger association between stairs climbed and LBP prevalence was found for female respondents with acute LBP (P = 0.009). CONCLUSIONS: More weekly stairs climbed was associated with a lower LBP prevalence among females, especially with respect to acute LBP. Randomized, longitudinal research is, however, required to confirm a relationship between stair climbing and LBP.

Noninvasive Evaluation of Cardiac Chamber Pressures Using Subharmonic-Aided Pressure Estimation With Definity Microbubbles.

BACKGROUND: Noninvasive and accurate assessment of intracardiac pressures has remained an elusive goal of noninvasive cardiac imaging. OBJECTIVES: The purpose of this study was to investigate if errors in intracardiac pressures obtained noninvasively using contrast microbubbles and the subharmonic-aided pressure estimation (SHAPE) technique are <5 mm Hg. METHODS: In a nonrandomized institutional review board-approved clinical trial (NCT03243942), patients scheduled for a left-sided and/or right-sided heart catheterization procedure and providing written informed consent were included. A standard-of-care catheterization procedure was performed advancing clinically used pressure catheters into the left and/or right ventricles and/or the aorta. After pressure catheter placement, patients received an infusion of Definity microbubbles (n = 56; 2 vials diluted in 50 mL of saline; infusion rate: 4-10 mL/min) (Lantheus Medical Imaging). Then SHAPE data was acquired using a validated interface developed on a SonixTablet scanner (BK Medical Systems) synchronously with the pressure catheter data. A conversion factor (mm Hg/dB) was derived from SHAPE data and measurements with a SphygmoCor XCEL PWA device (ATCOR Medical) and was combined with SHAPE data from the left and/or the right ventricles to obtain clinically relevant systolic and diastolic ventricular pressures. RESULTS: The mean value of absolute errors for left ventricular minimum and end diastolic pressures were 2.9 ± 2.0 and 1.7 ± 1.2 mm Hg (n = 26), respectively, and for right ventricular systolic pressures was 2.2 ± 1.5 mm Hg (n = 11). Two adverse events occurred during Definity infusion; both were resolved. CONCLUSIONS: These results indicate that the SHAPE technique with Definity microbubbles is encouragingly efficacious for obtaining intracardiac pressures noninvasively and accurately.

Subharmonic microbubble emissions for noninvasively tracking right ventricular pressures.

Right heart catheterization is often required to monitor intra-cardiac pressures in a number of disease states. Ultrasound contrast agents can produce pressure modulated subharmonic emissions that may be used to estimate right ventricular (RV) pressures. A technique based on subharmonic acoustic emissions from ultrasound contrast agents to track RV pressures noninvasively has been developed and its clinical potential evaluated. The subharmonic signals were obtained from the aorta, RV, and right atrium (RA) of five anesthetized closed-chest mongrel dogs using a SonixRP ultrasound scanner and PA4-2 phased array. Simultaneous pressure measurements were obtained using a 5-French solid state micromanometer tipped catheter. Initially, aortic subharmonic signals and systemic blood pressures were used to obtain a calibration factor in units of millimeters of mercury per decibel. This factor was combined with RA pressures (that can be obtained noninvasively) and the acoustic data from the RV to obtain RV pressure values. The individual calibration factors ranged from -2.0 to -4.0 mmHg/dB. The subharmonic signals tracked transient changes in the RV pressures within an error of 0.6 mmHg. Relative to the catheter pressures, the mean errors in estimating RV peak systolic and minimum diastolic pressures, and RV relaxation [isovolumic negative derivative of change in pressure over time (-dP/dt)] by use of the subharmonic signals, were -2.3 mmHg, -0.8 mmHg, and 2.9 mmHg/s, respectively. Overall, acoustic estimates of RV peak systolic and minimum diastolic pressures and RV relaxation were within 3.4 mmHg, 1.8 mmHg, and 5.9 mmHg/s, respectively, of the measured pressures. This pilot study demonstrates that subharmonic emissions from ultrasound contrast agents have the potential to noninvasively track in vivo RV pressures with errors below 3.5 mmHg.

Advance Care Planning and Goals-of-Care Decisions Among Veterans With Malignancy.

BACKGROUND: There is a limited knowledge base about factors affecting advance directives and code status decisions among veterans with malignancy. In addition, few studies have focused on the benefit of palliative care (PC) in goals-of-care discussions among veterans with cancer. OBJECTIVES: This study examined advance care planning and goals-of-care decisions among veterans with malignancy. METHODS: Demographic and clinical data were obtained using retrospective chart analysis. Patient characteristics were analyzed using univariate descriptive statistics. To compare patients with and without a do-not-resuscitate (DNR) decision, chi-square test was performed. FINDINGS: More than half of the patients in the study were referred to PC within one year of their cancer diagnosis. Most had documented metastatic disease at the time of their PC referral. Veterans with prostate cancer were more likely to elect full code status. In this study, White veterans were more likely to choose a DNR order than African American veterans.

Comparing Central Aortic Pressures Obtained Using a SphygmoCor Device to Pressures Obtained Using a Pressure Catheter.

BACKGROUND: This study compared aortic pressures estimated using a SphygmoCor XCEL PWA device (ATCOR, Naperville, IL) noninvasively with aortic pressures obtained using pressure catheters during catheterization procedures and analyzed the impact of a linear-fit function on the estimated pressure values. METHODS: One hundred and thirty-six patients scheduled for cardiac catheterization procedure were enrolled in IRB approved studies. Catheterization procedures were performed according to standard-of-care to acquire aortic pressure measurements. Immediately after the catheterization procedure with the pressure catheters removed, while the patients were still in the catheterization laboratory, central aortic pressures were estimated with the SphygmoCor device (using its inbuilt transfer function). The error between measured and estimated aortic pressures was evaluated using Bland-Altman analysis (n = 93). A linear-fit was performed between the measured and estimated pressures, and using the linear equation the error measurements were repeated. A bootstrap analysis was performed to test the generalizability of the linear-fit function. In a subset of cases (n = 13), central aortic pressure values were also obtained using solid-state high-fidelity catheters (Millar, Houston, TX), and the error measurements were repeated. RESULTS: The magnitude of errors between the measured and estimated aortic pressures (mean errors >6.4 mm Hg; mean errors >8.0 mm Hg in the subset) were reduced to less than 1 mm Hg after using the linear-fit function derived in this study. CONCLUSIONS: For the population examined in this study, the SphygmoCor data must be used with the linear-fit function to obtain aortic pressures that are comparable to the measurements obtained using pressure catheters.

Pharmacy Students' Perspectives on Interprofessional Learning in a Simulated Patient Care Ward Environment.

Objective. To assess pharmacy students' opinions of an interprofessional learning (IPL) course in their final year of the Bachelor of Pharmacy program at The University of Auckland. Methods. Pharmacy students participated in the second day of a two-day simulation-based course, WardSim, alongside medical and nursing students in an acute care, hospital ward setting. After finishing the course, all students were asked to complete a questionnaire. The responses of pharmacy, nursing, and medical students on the scaled questions were compared. An in-depth thematic analysis of the pharmacy students' responses to the open-ended questions was completed using an iterative process. Results. Significant differences were found among the students' responses regarding the prioritization of care, systematic assessment of patients, and communication strategies. Pharmacy students had less favourable responses regarding the IPL experience than medical and nursing students. However, overall responses were positive. Some of the themes that emerged among the pharmacy students' responses included: learning communication tools, being assertive in communicating with other health care professionals, and understanding their own and others' roles in the health care team. Furthermore, some pharmacy students reported feeling underprepared for and underutilized during patient care scenarios. Conclusion. An IPL experience in an acute patient care setting demonstrated clear and beneficial learning outcomes for pharmacy students, especially in regards to communicating and understanding their roles and those of others on their team. Tailoring the pre-work or scenarios for the IPL experience to be more pharmacy orientated and having pharmacy students participate on both days may improve the preparedness for IPL.

Non-Invasive Intra-cardiac Pressure Measurements Using Subharmonic-Aided Pressure Estimation: Proof of Concept in Humans.

This study evaluated the feasibility of employing non-invasive intra-cardiac pressure estimation using subharmonic signals from ultrasound contrast agents in humans. This institutional review board-approved proof-of-concept study included 15 consenting patients scheduled for left and right heart catheterization. During the catheterization procedure, Definity was infused intra-venously at 4-10 mL/min. Ultrasound scanning was performed with a Sonix RP using pulse inversion, three incident acoustic output levels and 2.5-MHz transmit frequency. Radiofrequency data were processed and subharmonic amplitudes were compared with the pressure catheter data. The correlation coefficient between subharmonic signals and pressure catheter data ranged from -0.3 to -0.9. For acquisitions with optimum acoustic output, pressure errors between the subharmonic technique and catheter were as low as 2.6 mmHg. However, automatically determining optimum acoustic output during scanning for each patient remains to be addressed before clinical applicability can be decided.

Use of a fictitious community-based virtual teaching platform to aid in the teaching of pharmacy practice skills: Student perspectives after initial implementation.

BACKGROUND: Providing patient-centred care requires pharmacy students to learn how to interact effectively and understand individual differences that can influence patients' health. The School of Pharmacy at The University of Auckland, New Zealand (NZ), developed a virtual teaching platform, called NZ Pharmville, which consisted of twenty-one community-based patients who are members of six families; each family had a video vignette associated with it. Bachelor of Pharmacy (BPharm) students, enrolled in the third year pharmacy practice course, were able to view these recorded vignettes as part of their weekly pre-laboratory work for the course. All the clinical cases within the course were based on this community, with the aim of increasing the realism in the practical sessions and increasing patient-centred learning. This study aimed to explore the perspectives of pharmacy students regarding the integration of this virtual community into a third year undergraduate pharmacy practice course. METHODS: An anonymous, voluntary survey which consisted of twenty-one items, 13 requiring a Likert scale response and 8 requiring free text responses, was distributed to all students who had completed the third year pharmacy practice course. The responses to the questions were collated and analysed. Responses to questions one to thirteen were recorded in Excel, and results were presented as the combination of strongly agree and agree, strongly disagree and disagree and neutral. Responses to free text questions were read multiple times before being coded by two members of the research team into broad themes aligned to the overall aims of the evaluation. RESULTS: Eighty-six (80.4 %) of the eligible students completed the survey and the majority of responses were positive towards the benefits of using the virtual community in the course. Responses indicated that many of the students found the integration of the virtual community to be useful preparation for their practical sessions and the majority of students felt that the vignettes made it easier to develop empathy for the patients rather than reading about them. CONCLUSION: The use of virtual communities, for example, NZ Pharmville, show promise as a platform to aid in teaching and learning. The resources in NZ Pharmville allow students ongoing access to patient video clips that attempt to depict a real life situation, and enable students to engage with the fictional characters. The virtual community provided an educational experience which was well received by students. This teaching method appeared to promote active patient-centered learning and allowed students to reflect on and revisit these skills on a weekly basis.

Is there potential for the future provision of triage services in community pharmacy?

BACKGROUND: Worldwide the demands on emergency and primary health care services are increasing. General practitioners and accident and emergency departments are often used unnecessarily for the treatment of minor ailments. Community pharmacy is often the first port of call for patients in the provision of advice on minor ailments, advising the patient on treatment or referring the patient to an appropriate health professional when necessary. The potential for community pharmacists to act as providers of triage services has started to be recognised, and community pharmacy triage services (CPTS) are emerging in a number of countries. This review aimed to explore whether key components of triage services can be identified in the literature surrounding community pharmacy, to explore the evidence for the feasibility of implementing CPTS and to evaluate the evidence for the appropriateness of such services. METHODS: Systematic searches were conducted in MEDLINE, EMBASE and International Pharmaceutical Abstracts (IPA) databases from 1980 to March 2016. RESULTS: Key elements of community pharmacy triage were identified in 37 studies, which were included in the review. When a guideline or protocol was used, accuracy in identifying the presenting condition was high, with concordance rates ranging from 70 % to 97.6 % between the pharmacist and a medical expert. However, when guidelines and protocols were not used, often questioning was deemed insufficient. Where other health professionals had reviewed decisions made by pharmacists and their staff, e.g. around advice and referral, the decisions were considered to be appropriate in the majority of cases. Authors of the included studies provided recommendations for improving these services, including use of guidelines/protocols, education and staff training, documentation, improving communication between health professional groups and consideration of privacy and confidentiality. CONCLUSION: Whilst few studies had specifically trialled triage services, results from this review indicate that a CPTS is feasible and appropriate, and has the potential to reduce the burden on other healthcare services. Questions still remain on issues such as ensuring the consistency of the service, whether all pharmacies could provide this service and who will fund the service.

Noninvasive LV pressure estimation using subharmonic emissions from microbubbles.

To develop a new noninvasive approach to quantify left ventricular (LV) pressures using subharmonic emissions from microbubbles, an ultrasound scanner was used in pulse inversion grayscale mode; unprocessed radiofrequency data were obtained with pulsed wave Doppler from the aorta and/or LV during Sonazoid infusion. Subharmonic data (in dB) were extracted and processed. Calibration factor (mm Hg/dB) from the aortic pressure was used to estimate LV pressures. Errors ranged from 0.19 to 2.50 mm Hg when estimating pressures using the aortic calibration factor, and were higher (0.64 to 8.98 mm Hg) using a mean aortic calibration factor. Subharmonic emissions from ultrasound contrast agents have the potential to noninvasively monitor LV pressures.

Noninvasive estimation of dynamic pressures in vitro and in vivo using the subharmonic response from microbubbles.

The purpose of this study was to develop and validate a noninvasive pressure estimation technique based on subharmonic emissions from a commercially available ultrasound contrast agent and scanner, unlike other studies that have either adopted a single-element transducer approach and/ or use of in-house contrast agents. Ambient pressures were varied in a closed-loop flow system between 0 and 120 mmHg and were recorded by a solid-state pressure catheter as the reference standard. Simultaneously, the ultrasound scanner was operated in pulse inversion mode transmitting at 2.5 MHz, and the unprocessed RF data were captured at different incident acoustic pressures (from 76 to 897 kPa). The subharmonic data for each pulse were extracted using band-pass filtering with averaging, and subsequently processed to eliminate noise. The incident acoustic pressure most sensitive to ambient pressure fluctuations was determined, and then the ambient pressure was tracked over 20 s. In vivo validation of this technique was performed in the left ventricle (LV) of 2 canines. In vitro, the subharmonic signal could track ambient pressure values with r(2) = 0.922 (p < 0.001), whereas in vivo, the subharmonic signal tracked the LV pressures with r(2) > 0.790 (p < 0.001) showing a maximum error of 2.84 mmHg compared with the reference standard. In conclusion, a subharmonic ultrasound-based pressure estimation technique, which can accurately track left ventricular pressures, has been established.
