Using quality improvement to address social determinants of health needs in perinatal care.

There are unacceptable racial inequities in perinatal outcomes in the United States. Social determinants of health (SDOH) are associated with health outcomes and contribute to disparities in maternal and newborn health. In this article, we (1) review the literature on SDOH improvement in the perinatal space, (2) describe the SDOH work facilitated by the Illinois Perinatal Quality Collaborative (ILPQC) in the Birth Equity quality improvement initiative, (3) detail a hospital's experience with implementing strategies to improve SDOH screening and linkage to needed resources and services and (4) outline a framework for success for addressing SDOH locally. A state-based quality improvement initiative can facilitate implementation of strategies to increase screening for SDOH. Engaging patients and communities with specific actionable strategies is key to increase linkage to needed SDOH resources and services.

Reducing severe maternal morbidity for birthing persons with severe hypertension through a statewide quality improvement initiative.

BACKGROUND: Hypertensive disorders of pregnancy are a leading preventable cause of severe maternal morbidity and maternal mortality worldwide. OBJECTIVE: To assess the improvement in hospital care processes and patient outcomes associated with hypertensive disorders of pregnancy after introduction of a statewide Severe Maternal Hypertension Quality Improvement Initiative. STUDY DESIGN: A prospective cohort design comparing outcomes before and after introduction of the Illinois Perinatal Quality Collaborative statewide hypertension quality improvement initiative among 108 hospitals across Illinois. Participating hospitals recorded data for all cases of new-onset severe hypertension (>160 mm Hg systolic or >110 mm Hg diastolic) during pregnancy through 6 weeks postpartum from May 2016 to December 2017. Introduction of the statewide quality improvement initiative included implementation of severe maternal hypertension protocols, standardized patient education and discharge planning, rapid access to medications and standardized treatment order sets, and provider and nurse education. The main outcome measure was the reduction of severe maternal morbidity for pregnant/postpartum patients with severe hypertension. Key process measures include time to treatment of severe hypertension, frequency of provider/nurse debriefs, appropriate patient education, and early postpartum follow-up. RESULTS: Data were reported for 8073 cases of severe maternal hypertension. The frequency of patients with new-onset severe hypertension treated within 60 minutes increased from 41% baseline to 87% (P<.001) at the end of the initiative. The initiative was associated with increased proportion of patients receiving preeclampsia education at discharge (41% to 89%; P<.001), scheduling follow-up appointments within 10 days of discharge (68% to 83%; P<.001), and having a care team debrief after severe hypertension was diagnosed (17% to 59%; P<.001). Conversely, severe maternal morbidity was reduced from 11.5% baseline to 8.4% (P<.002) at the end of the study period. Illinois hospitals have achieved time to treatment goal regardless of hospital characteristics including geography, birth volume, and patient mix. CONCLUSION: Introduction of a statewide quality improvement effort was associated with improved time to treatment of severe hypertension and increased frequency of provider/nurse debriefs, appropriate patient education, and early postpartum follow-up scheduled at discharge, and reduced severe maternal morbidity.

Implementation of perinatal quality collaborative statewide initiative improves obstetrical opioid use disorder care and outcomes.

BACKGROUND: Maternal deaths resulting from opioid use disorder have been increasing across the United States. Opioid use disorder among pregnant persons is associated with adverse pregnancy outcomes, including preterm birth, along with racial disparities in optimal opioid use disorder care. OBJECTIVE: This study aimed to evaluate whether the Illinois Perinatal Quality Collaborative implementation of the Mothers and Newborns affected by Opioids - Obstetric quality improvement initiative was associated with improvement in opioid use disorder identification, provision of optimal opioid use disorder care for birthing patients, and reduction in racial gaps in optimal opioid use disorder care. STUDY DESIGN: Using a prospective cohort design, hospitals reported monthly key measures for all patients with opioid use disorder at delivery between July 2018 and December 2020. The Illinois Perinatal Quality Collaborative facilitates collaborative learning opportunities, rapid response data, and quality improvement support. Generalized linear mixed-effects regression models were used to evaluate improvement in optimal opioid use disorder care, including increases in linkages to medication-assisted treatment, recovery treatment services, and naloxone counseling across time, and to determine whether optimal opioid use disorder care was associated with positive outcomes, such as lower odds of preterm birth. RESULTS: A total of 91 hospitals submitted data on 2095 pregnant persons with opioid use disorder. For the primary outcomes, the rates of patients receiving medication-assisted treatment and recovery treatment services improved across the initiative from 41% to 78% and 48% to 67%, respectively. For the secondary outcomes, the receipt of recovery treatment services and both recovery treatment services and medication-assisted treatment provided prenatally before delivery admission was associated with lower odds of preterm birth (adjusted odds ratio: 0.67 [95% confidence interval, 0.50-0.91] and 0.49 [95% confidence interval, 0.31-0.75], respectively). During the first quarter of the initiative, Black patients with opioid use disorder were less likely to be linked to medication-assisted treatment than White patients (23% vs 48%, respectively); however, an increase in medication-assisted treatment rates across the initiative occurred for all patients, with the greatest improvement for Black patients with an associated reduction in this disparity gap with >70% of both Black and White patients linked to medication-assisted treatment. CONCLUSION: The Mothers and Newborns affected by Opioids - Obstetric initiative was associated with improvement in optimal opioid use disorder care for pregnant patients across Illinois hospitals, additionally racial disparities in opioid use disorder care was reduced across the initiative. Our findings implicate how optimal opioid use disorder care can improve pregnancy outcomes and close persistent racial gaps for pregnant individuals with opioid use disorder.

A Mixed Methods Evaluation of a Quality Improvement Model to Optimize Perinatal and Primary Care in the Community Health Setting.

PURPOSE: Many maternal deaths occur beyond the acute birth encounter. There are opportunities for improving maternal health outcomes through facilitated quality improvement efforts in community settings, particularly in the postpartum period. We used a mixed methods approach to evaluate a collaborative quality improvement (QI) model in 6 Chicago Federally Qualified Health Centers (FQHCs) that implemented workflows optimizing care continuity in the extended postpartum period for high-risk prenatal patients. METHODS: The Quality Improvement Learning Collaborative focused on the implementation of a registry of high-risk prenatal patients to link them to primary care and was implemented in 2021; study data were collected in 2021-2022. We conducted a quantitative evaluation of FQHC-reported aggregate structure, process, and outcomes data at baseline (2020) and monthly (2021). Qualitative analysis of semistructured interviews of participating FQHC staff focused on the experience of participating in the collaborative. RESULTS: At baseline, none of the 6 participating FQHCs had integrated workflows connecting high-risk prenatal patients to primary care; by the end of implementation of the QI intervention, such workflows had been implemented at 19 sites across all 6 FQHCs, and 54 staff were trained in using these workflows. The share of high-risk patients transitioned to primary care within 6 months of delivery significantly increased from 25% at baseline to 72% by the end of implementation. Qualitative analysis of interviews with 11 key informants revealed buy-in, intervention flexibility, and collaboration as facilitators of successful engagement, and staffing and data infrastructure as participation barriers. CONCLUSIONS: Our findings show that a flexible and collaborative QI approach in the FQHC setting can help optimize care delivery. Future evaluations should incorporate the patient experience and patient-level data for comprehensive analysis.

Optimizing accuracy of birth certificate data through a statewide quality improvement initiative in Illinois.

OBJECTIVE: This study examines improvement in birth certificate accuracy during a statewide quality improvement initiative. STUDY DESIGN: Participating hospitals systematically sampled 10 delivery medical records per month and compared them to corresponding birth certificates for accuracy. Accuracy was computed before implementing the initiative (Aug-Oct 2014), end of phase 1 (July 2015) and end of phase 2 (Nov-Dec 2015). Accuracy data was aggregated and compared across time points using a linear mixed model and by hospital characteristics. RESULTS: 105 hospitals participated. Birth certificate accuracy increased between baseline (89.59%) and end of phase 2 (97.00%, p < 0.001). Percent accuracy at baseline was lowest in hospitals serving at-risk populations (p < 0.01). These hospitals showed relatively greater increases in overall accuracy with no difference in accuracy by the end of the initiative. CONCLUSIONS: A statewide QI effort contributed to improvements in birth certificate accuracy. Hospitals serving at-risk populations exhibited the greatest benefit and improvement.

Exogenous Application of Methyl Salicylate Induces Defence in Brassica against Peach Potato Aphid Myzus persicae.

Plants use a variety of secondary metabolites to defend themselves against herbivore insects. Methyl salicylate (MeSA) is a natural plant-derived compound that has been used as a plant defence elicitor and a herbivore repellent on several crop plants. The aim of this study was to investigate the effect of MeSA treatment of Brassica rapa subsp. chinensis ('Hanakan' pak choi) on its interactions with peach potato aphids, Myzus persicae, and their natural enemy, Diaeretiella rapae. For this, we selected two concentrations of MeSA (75 mg/L and 100 mg/L). Our results showed that aphid performance was significantly reduced on plants treated with MeSA (100 mg/L). In a cage bioassay, the MeSA (100 mg/L)-treated plants showed lower adult survival and larviposition. Similarly, the MeSA (100 mg/L)-treated plants had a significantly lower aphid settlement in a settlement bioassay. In contrast, the M. persicae aphids did not show any significant difference between the MeSA (75 mg/L)-treated and control plants. In a parasitoid foraging bioassay, the parasitoid D. rapae also did not show any significant difference in the time spent on MeSA-treated and control plants. A volatile analysis showed that the MeSA treatment induced a significant change in volatile emissions, as high numbers of volatile compounds were detected from the MeSA-treated plants. Our results showed that MeSA has potential to induce defence in Brassica against M. persicae and can be utilised in developing sustainable approaches for the management of peach potato aphids.

Comparison of Home-Blenderized Formula and Commercial Enteral Formulas for Gastrostomy Tube-Fed Children: A Retrospective, Prospective Cohort Study.

Background Blenderized gastrostomy tube feedings (BGTFs) consist of pureed table foods and liquids that are administered as enteral tube feedings. Compared to commercial enteral formulas (CEFs), BGTF has been shown to have fewer side effects. Despite these results, apprehensions have been raised about microbial contamination, nutritional deficiencies or surplus, risk of gastrostomy tube (GT) blockages, and lack of consistency in clinical outcomes. The goal of this retrospective, prospective, 18-month-long study is to report the clinical and nutritional outcomes of GT-dependent pediatric patients who attended a multidisciplinary feeding clinic. Methodology After Institutional Review Board (IRB) approval and consent were obtained, 25 children who were receiving tube feeding via G were enrolled in a retrospective, prospective, observational, cohort study from August 2019 to February 2021. A multidisciplinary team was formed, and multivariate logistic regression was performed comparing subjects on BGTF versus CEF, per os diet versus nil per os, CEF versus homemade blenderized tube feeding (HBTF) versus blenderized tube feeding (BTF), and how they compared at the beginning and end of the study. Results The mean age of the patients was 4.4 years (SD ±2.2). Gastroesophageal reflux disease (GERD) and short bowel syndrome (SBS) were the most common comorbid gastrointestinal (GI) conditions. Of the 25 patients enrolled in the study, seven were initially on BGTF, while 14 ended the study on BGTF. There were no statistically significant differences in malnutrition status, feeding intolerance, emergency room visits, hospitalizations, and GT blockages between all different comparison groups when comparing between the CEF versus HBTF versus commercial blenderized tube feeding (CBTF) groups. Of the patients who were in the BGTF group, there was a resolution of vitamin A deficiency, vitamin D deficiency, and anemia (n = 1). In total, two patients had resolved vitamin deficiencies, namely, vitamins A and D. Conclusions When comparing BGTF and CEF, there was no statistically significant difference in outcomes. This study suggests that BGTF is at least equivalent to CEF in clinical outcomes, meaning BGTF should be considered standard nutrition for GT-dependent patients.

Medical cannabis in schools: The experiences of caregivers.

Objectives: Implementing medical cannabis (MC) into a child's daily routine can be challenging and there is a lack of guidance for its therapeutic use in schools in Canada. Our objective was to learn about the experiences of caregivers of school-aged children who require MC. Methods: Qualitative description was used and caregivers were interviewed about MC in schools and in general. The transcripts were entered into Dedoose software for qualitative analysis and content analysis was performed. Sentences and statements were ascribed line by line into meaning units and labelled with codes, and organized according to categories and subcategories. Results: Twelve caregivers of school-aged children who take MC participated. The most common reasons for treatment were drug-resistant epilepsy (DRE), autism, or other developmental disorders. Approximately half of the participants' children (n = 6) took MC during the school day and most (5/6) perceived their experiences to be positive or neutral but reported a lack of knowledge about MC. While data saturation was not reached regarding MC in schools, rich dialogues were garnered about MC in general and three categories were identified: challenges (subcategories stigma, finding an authorizer, cost, dosing, and supply); parents as advocates (subcategories required knowledge, attitudes, skills, and sources of information); and caregiver relief for positive outcomes. Conclusions: Caregivers demonstrate remarkable tenacity despite the many challenges associated with MC use. Education and practice change are needed to ensure that children using MC can benefit from or continue to experience its positive outcomes within the school environment and beyond.

Factors Affecting Pollination and Pollinators in Oil Palm Plantations: A Review with an Emphasis on the Elaeidobius kamerunicus Weevil (Coleoptera: Curculionidae).

Pollination is crucial for oil palm yield, and its efficiency is influenced by multiple factors, including the effectiveness of Elaeidobius kamerunicus weevils as pollinators in Southeast Asia. Weevils transfer pollen between male and female flowers, leading to successful fertilization and fruit development, which contributes to higher oil palm yields and increased production of valuable oil. Understanding and conserving the weevil population is important for sustainable oil palm cultivation practices. The interaction between pollinators, including weevils, and environmental factors is complex, involving aspects such as pollinator behavior, abundance, diversity, and effectiveness, which are influenced by weather, landscape composition, and pesticide use. Understanding these interactions is critical for promoting sustainable pollination practices, including effective pest management and maintaining optimal pollinator populations. This review discusses various abiotic and biotic factors that affect pollination and pollinators in oil palm plantations, with a particular focus on weevils as primary pollinators. Factors such as rainfall, humidity, oil palm species, temperature, endogamy, parasitic nematodes, insecticides, predators, and proximity to natural forests can impact the weevil population. Further research is recommended to fill knowledge gaps and promote sustainable pollination practices in the oil palm industry.

What Can State Medical Boards Do to Effectively Address Serious Ethical Violations?

State Medical Boards (SMBs) can take severe disciplinary actions (e.g., license revocation or suspension) against physicians who commit egregious wrongdoing in order to protect the public. However, there is noteworthy variability in the extent to which SMBs impose severe disciplinary action. In this manuscript, we present and synthesize a subset of 11 recommendations based on findings from our team's larger consensus-building project that identified a list of 56 policies and legal provisions SMBs can use to better protect patients from egregious wrongdoing by physicians.

Medical Cannabis in Canadian Schools: A Scoping Review of Existing Policies.

Objective: An increasing number of children and youth in Canada are taking medical cannabis for complex medical conditions. While they deserve safe and consistent access to pharmacotherapy throughout the day, administrative policies on cannabis use in schools are inconsistent. A scoping review identified policies and publications associated with medical cannabis in Canadian schools. Methods: Five databases (Scopus, PubMed, CINAHL, EMBASE, and Web of Science) were searched to identify scientific literature. Legislation in each province and territory and Ministry of Education webpages were reviewed for pertinent laws and policies regarding cannabis use in schools. Results: The scientific search resulted in 1289 articles. The five included articles pertain to implications for school nurses in the United States, which are not relevant to the Canadian context. A search of Ministry of Education websites identified only one policy with information regarding medical cannabis in schools (from Ontario). Federal legislation (the Cannabis Act) does not specifically address medical cannabis in schools, and there is a lack of consistency in terminology and clarity within provincial and territorial laws. All provinces and territories prohibit smoking and vaping of cannabis on school property and some provinces prohibit any method of cannabis consumption. Conclusions: In Canada, there is a lack of guidance for medical cannabis administration, storage, and disposal in schools, with some policies explicitly prohibiting this type of treatment. This shifts the burden to families to individually create plans school by school. A federally harmonized approach to supporting children who take cannabis for medical purposes ought to be explored.

Predicting Postpartum Transition to Primary Care in Community Health Centers.

INTRODUCTION: Although the transition to primary care after routine postpartum care has been recommended to mitigate adverse maternal outcomes, little is known about real-world transition patterns. The objective of this study was to describe the patterns and predictors of transition in a postpartum cohort receiving care at federally qualified health centers and a subcohort of clinically high-risk patients. METHODS: Electronic health record data collected between 2017 and 2019 were analyzed in 2021 for unadjusted analyses and multivariable regression models for both the full and high-risk cohorts. The primary outcome was completion of a primary care visit within 6 months of delivery. Primary predictors in both cohorts were insurance loss, postpartum visit, first-trimester visit, and medical visit within the year prepregnancy; for the full cohort, high-risk status was also studied. RESULTS: The full cohort (N=7,926) analysis showed that 17.3% completed a primary care visit. In unadjusted and adjusted analysis, all 5 predictors were significantly associated with primary care visit completion; 25.0% of high-risk patients completed a primary care visit, and patients who lost insurance had 66% lower odds of primary care visit completion (95% CI=0.24, 0.48). In unadjusted and adjusted analysis for the high-risk cohort (n=1,956, 24.7% of full cohort), all predictors except postpartum visit were significantly associated with primary care visit completion. CONCLUSIONS: Postpartum patients at federally qualified health centers transitioned to primary care at low rates; insurance loss was one significant barrier to care. Strategies to increase continuity, including improving insurance access, should be studied. Future research is needed to study structural inequity, the impact of primary care on maternal outcomes, and patient experience.

Improving the Timely Delivery of Antihypertensive Medication for Severe Perinatal Hypertension in Pregnancy and Postpartum.

OBJECTIVE: Sustained blood pressures ≥160/110 during pregnancy and the postpartum period require timely antihypertensive therapy. Hospital-level experiences outlining the efforts to improve timely delivery of care within 60 minutes have not been described. The objective of this analysis was to assess changes in care practices of an inpatient obstetrical health care team following the implementation of a quality improvement initiative for severe perinatal hypertension during pregnancy and the postpartum period. STUDY DESIGN: In January 2016, NorthShore University HealthSystem Evanston Hospital launched a quality improvement initiative focusing on perinatal hypertension, as part of a larger, statewide quality initiative via the Illinois Perinatal Quality Collaborative. We performed a retrospective cohort study of all pregnant and postpartum patients with sustained severely elevated blood pressure (two severely elevated blood pressures ≤15 minutes apart) with baseline data from 2015 and data collected during the project from 2016 through 2017. Changes in clinical practice and outcomes were compared before and after the start of the project. Statistical process control charts were used to demonstrate process-behavior changes over time. RESULTS: Comparing the baseline to the last quarter of 2017, there was a significant increase in the administration of medication within 60 minutes for severe perinatal hypertension (p <0.001). Implementation of a protocol for event-specific debriefing for each severe perinatal hypertension episode was associated with increased odds of the care team administering medication within 60 minutes of the diagnosis of severe perinatal hypertension (adjusted odds ratio 3.20, 95% confidence interval 1.73-5.91, p < 0.01). CONCLUSION: Implementation of a quality improvement initiative for perinatal hypertension associated with pregnancy and postpartum improved the delivery of appropriate and timely therapy for severely elevated blood pressures and demonstrated the impact of interdisciplinary communication in the process. KEY POINTS: · Process of hospital-level implementation of a state quality improvement initiative.. · Evidence of improvement in care delivery for severe perinatal hypertension (HTN).. · Episode related debriefing by the clinical team improved perinatal HTN care..

Existing validated clinical prediction rules for predicting response to physiotherapy interventions for musculoskeletal conditions have limited clinical value: A systematic review.

OBJECTIVE: To systematically review clinical prediction rules (CPRs) that have undergone validation testing for predicting response to physiotherapy-related interventions for musculoskeletal conditions. STUDY DESIGN AND SETTING: PubMed, EMBASE, CINAHL and Cochrane Library were systematically searched to September 2020. Search terms included musculoskeletal (MSK) conditions, physiotherapy interventions and clinical prediction rules. Controlled studies that validated a prescriptive CPR for physiotherapy treatment response in musculoskeletal conditions were included. Two independent reviewers assessed eligibility. Original derivation studies of each CPR were identified. Risk of bias was assessed with the PROBAST tool (derivation studies) and the Cochrane Effective Practice and Organisation of Care group criteria (validation studies). RESULTS: Nine studies aimed to validate seven prescriptive CPRs for treatment response for MSK conditions including back pain, neck pain, shoulder pain and carpal tunnel syndrome. Treatments included manipulation, traction and exercise. Seven studies failed to demonstrate an association between CPR prediction and outcome. Methodological quality of derivation studies was poor and for validation studies was good overall. CONCLUSION: Results do not support the use of any CPRs identified to aid physiotherapy treatment selection for common musculoskeletal conditions, due to methodological shortcomings in the derivation studies and lack of association between CPR and outcome in validation studies.

Advances in Maternal Fetal Medicine: Perinatal Quality Collaboratives Working Together to Improve Maternal Outcomes.

State-based perinatal quality collaboratives (PQCs) address preventable causes of maternal and infant morbidity and mortality by implementing statewide quality improvement (QI) initiatives. They work with hospital clinical teams, obstetric provider and nursing leaders, patients and families, public health officials, and other stakeholders to provide opportunities for collaborative learning, rapid-response data, and QI science support to achieve clinical culture change. PQCs show that the application of collaborative improvement science methods to advance evidence-informed clinical practices using QI strategies contributes to improved perinatal outcomes. With appropriate staffing, infrastructure, and partnerships, PQCs can achieve sustainable improvements in perinatal care.

Development of the REACH (Real Education About Cannabis and Health) Program for Canadian Youth.

BACKGROUND: Because cannabis use in children can have negative consequences, the recent legalization of recreational cannabis for adults in Canada creates an urgent need for youth education. METHOD: A multidisciplinary clinical rotation was developed wherein nursing and pharmacy students collaborated with youth (grades 7 through 10) to construct an educational program about cannabis. Four schools participated, representing a variety of socioeconomic demographics. Feedback was solicited from students and stakeholders. The purpose of this project was to create REACH (Real Education About Cannabis and Health), a toolkit and curriculum resource that includes lesson plans for teachers covering the science of cannabis, social science implications, peer pressure, decision making and harm reduction, videos featuring youth testimonials, and supplemental resources. RESULTS: Preliminary feedback suggests the materials are engaging and informative. CONCLUSION: A collaboration of health science students with youth in schools resulted in an authentic and relatable educational program about cannabis. Future studies will evaluate REACH's effectiveness in seventh- and ninth-grade students. [J Nurs Educ. 2020;59(8):465-469.].

A Framework to Harness the Power of Quality Collaboratives to Improve Perinatal Outcomes.

The Illinois Perinatal Quality Collaborative developed a framework for successfully engaging teams and implementing statewide obstetric and neonatal quality improvement (QI) initiatives. This framework includes: (1) engaging hospitals to create an environment of improvement; (2) motivating hospital teams to facilitate change at their hospital; and (3) supporting hospital teams through the 3 pillars of QI-collaborative learning opportunities, rapid-response data, and QI support-to achieve initiative goals and improve outcomes for mothers and newborns. Utilizing this framework, the Illinois Perinatal Quality Collaborative Severe Maternal Hypertension Initiative engaged teams and achieved initiative goals.

Comparison of two different radiofrequency ablation systems for renal artery denervation: Evaluation of short-term and long-term follow up.

OBJECTIVES: To assess the clinical efficacy of renal artery denervation (RAD) in our center and to compare the efficacy of two different radiofrequency (RF) systems. BACKGROUND: Several systems are available for RF renal denervation. Whether there is a difference in clinical efficacy among various systems remains unknown. METHODS: Renal artery denervation was performed on 43 patients with resistant hypertension using either the single electrode Symplicity Flex (n = 20) or the multi-electrode EnligHTN system (n = 23). Median post-procedural follow-up was 32.93 months. The primary outcome was post-procedural change in office blood pressure (BP) within 1 year (short-term follow-up). Secondary outcomes were change in office BP between 1 and 4 years (long-term follow-up) and the difference in office BP reduction between the two systems at each follow-up period. RESULTS: For the total cohort, mean baseline office BP (systolic/diastolic) was 174/94 mmHg. At follow-up, mean changes in office BP from baseline were -19.70/-11.86 mmHg (P < 0.001) and -21.90/-13.94 mmHg (P < 0.001) for short-term and long-term follow-up, respectively. The differences in office BP reduction between Symplicity and EnligHTN groups were 8.96/1.23 mmHg (P = 0.42 for systolic BP, P = 0.83 for diastolic BP) and 9.56/7.68 mmHg (P = 0.14 for systolic BP, P = 0.07 for diastolic BP) for short-term and long-term follow-up, respectively. CONCLUSIONS: In our cohort, there was a clinically significant office BP reduction after RAD, which persisted up to 4 years. No significant difference in office BP reduction between the two systems was found.
