Quantifying the association between doula care and maternal and neonatal outcomes.

BACKGROUND: The United States suffers from an increasing rate of severe maternal morbidity, paired with a wide disparity in maternal health by race. Doulas are posited to be a useful resource to increase positive outcomes and to decrease this disparity. OBJECTIVE: This study aimed to evaluate the association between doula care and a broad range of maternal and neonatal outcomes in various subpopulations. STUDY DESIGN: This was a retrospective cohort study of deliveries that were recorded from January 2021 to December 2022 at a single institution where they received prenatal care. The exposure was receipt of doula care prenatally and at delivery. We evaluated both the maternal (cesarean delivery, cesarean delivery of nulliparous, term, singleton, vertex infant, vaginal birth after cesarean, gestational hypertension, preeclampsia, postpartum emergency department visit, readmission, and attendance of postpartum office visit) and neonatal (neonatal intensive care unit admission, unexpected complications in term newborns, breastfeeding, preterm delivery, and intrauterine growth restriction) outcomes. Because our institution previously employed targeted outreach by offering doula services to patients at highest risk, we used multiple methods to generate an appropriate comparison population. We conducted a multivariate logistic regression and conditional regressions using propensity scores to model the likelihood of doula care to generate adjusted risk differences associated with doula care. Analyses were repeated in populations stratified by race (White vs Black) and then by payor status (public vs commercial). RESULTS: Our cohort included 17,831 deliveries; 486 of those received doula care and 17,345 did not. Patients who received doula care were more likely to self-report Black race, be publicly insured, and to live in a more disadvantaged neighborhood. Regardless of the analytical approach, for every 100 patients who received doula care, there were 15 to 34 more vaginal births after cesarean (adjusted risk difference, 15.6; 95% confidence interval, 3.8-27.4; adjusted risk difference, 34.2; 95% confidence interval, 0.046-68.0) and 5 to 6 more patients who attended a postpartum office visit (adjusted risk difference, 5.4; 95% confidence interval, 1.4-9.5; adjusted risk difference, 6.8; 95% confidence interval, 3.7-9.9) when compared with those who did not receive doula services. Infants born to these patients were 20% more like likely to be exclusively breastfed (adjusted risk ratio, 1.22; 95% confidence interval, 1.07-1.38), and doula care was associated with 3 to 4 fewer preterm births (adjusted risk difference, -3.8; 95% confidence interval, -6.1 to -1.5; -4.0; 95% confidence interval, -6.2 to -1.8) for every 100 deliveries that received doula care. Results were consistent regardless of race or insurance. Results were also consistent when doula care was redefined as having at least 3 prenatal encounters with a doula. CONCLUSION: Doula care was associated with more vaginal births after cesarean delivery, improved attendance of postpartum office visits, improved breastfeeding rates, and fewer preterm deliveries. The effect of doula care was consistent across race and insurance status.

Clinical Outcomes Associated With a Remote Postpartum Hypertension Monitoring Program.

OBJECTIVE: To evaluate differences in health care utilization and guideline adherence for postpartum individuals with hypertensive disorders of pregnancy (HDP) who are engaged in a remote monitoring program, compared with usual care. METHODS: This was a retrospective cohort study of postpartum individuals with HDP who delivered between March 2019 and June 2023 at a single institution. The primary exposure was enrollment in a remote hypertension management program that relies on patient home blood pressure (BP) measurement and centralized nursing team management. Patients enrolled in the program were compared with those receiving usual care. Outcomes included postpartum readmission, office visit within 6 weeks postpartum, BP measurement within 10 days, and initiation of antihypertensive medication. We performed multivariable logistic and conditional regression in a propensity score matched cohort. Propensity scores, generated by modeling likelihood of program participation, were assessed for even distribution by group, ensuring standardized bias of less than 10% after matching. RESULTS: Overall, 12,038 eligible individuals (6,556 participants, 5,482 in the control group) were included. Program participants were more likely to be White, commercially insured, be diagnosed with preeclampsia, and have higher prenatal and inpatient postpartum BPs. Differences in baseline factors were well-balanced after implementation of propensity score. Program enrollment was associated with lower 6-week postpartum readmission rates, demonstrating 1 fewer readmission for every 100 individuals in the program (propensity score-matched adjusted risk difference [aRD] -1.5, 95% CI, -2.6 to -0.46; adjusted risk ratio [aRR] 0.78, 95% CI, 0.65-0.93). For every 100 individuals enrolled in the program, 85 more had a BP recorded within 10 days (propensity score-matched aRD 85.4, 95% CI, 84.3-86.6), and six more had a 6-week postpartum office visit (propensity score-matched aRD 5.7, 95% CI, 3.9-7.6). Program enrollment was also associated with increased initiation of an antihypertensive medication postpartum (propensity score-matched aRR 4.44, 95% CI, 3.88-5.07). CONCLUSION: Participation in a postpartum remote BP monitoring program was associated with fewer postpartum hospital readmissions, higher attendance at postpartum visits, improved guideline adherence, and higher rates of antihypertensive use.

Leveraging data to support health equity in an integrated delivery and finance system.

Introduction: To accelerate healthcare transformation and advance health equity, scientists in learning health systems (LHSs) require ready access to integrated, comprehensive data that includes information on social determinants of health (SDOH). Methods: We describe how an integrated delivery and finance system leveraged its learning ecosystem to advance health equity through (a) a cross-sector initiative to integrate healthcare and human services data for better meeting clients' holistic needs and (b) a system-level initiative to collect and use patient-reported SDOH data for connecting patients to needed resources. Results: Through these initiatives, we strengthened our health system's capacity to meet diverse patient needs, address health disparities, and improve health outcomes. By sharing and integrating healthcare and human services data, we identified 281 000 Shared Services Clients and enhanced care management for 100 adult Medicaid/Special Needs Plan members. Over a 1-year period, we screened 9173 (37%) patients across UPMC's Women's Health Services Line and connected over 700 individuals to social services and supports. Conclusions: Opportunities exist for LHSs to improve, expand, and sustain their innovative data practices. As learnings continue to emerge, LHSs will be well positioned to accelerate healthcare transformation and advance health equity.

Postpartum Ambulatory Blood Pressure Patterns Following New-Onset Hypertensive Disorders of Pregnancy.

Importance: After a hypertensive disorder of pregnancy, hypertension can worsen in the postpartum period following hospital discharge. Risk factors for ongoing hypertension and associated outcomes have not been well characterized. Objective: To identify risk factors and characterize outcomes for individuals with ongoing hypertension and severe hypertension following hospital discharge post partum through a hospital system's remote blood pressure (BP) management program. Design, Setting, and Participants: This cohort study involved a population-based sample of individuals with a new-onset hypertensive disorder of pregnancy (preeclampsia or gestational hypertension) and no prepregnancy hypertension who delivered between September 2019 and June 2021. Participants were enrolled in a remote BP monitoring and management program at a postpartum unit at a referral hospital. Data analysis was performed from August 2021 to January 2023. Exposure: Inpatient postpartum BP categories. Main Outcomes and Measures: The primary outcomes were readmission and emergency department visits within the first 6 weeks post partum. Logistic regression was used to model adjusted odds ratios (aORs) and 95% CIs. Results: Of 2705 individuals in the cohort (mean [SD] age, 29.8 [5.7] years), 2214 (81.8%) had persistent hypertension post partum after hospital discharge, 382 (14.1%) developed severe hypertension after discharge, and 610 (22.6%) had antihypertensive medication initiated after discharge. Individuals with severe hypertension had increased odds of postpartum emergency department visits (aOR, 1.85; 95% CI, 1.17-2.92) and hospital readmissions (aOR, 6.75; 95% CI, 3.43-13.29) compared with individuals with BP normalization. When inpatient postpartum BP categories were compared with outpatient home BP trajectories to inform optimal thresholds for inpatient antihypertensive medication initiation, there was significant overlap between postdischarge BP trajectories among those with inpatient systolic BP greater than or equal to 140 to 149 mm Hg and/or diastolic BP greater than or equal to 90 to 99 mm Hg and those with systolic BP greater than or equal to 150 mm Hg and/or diastolic BP greater than or equal to 100 mm Hg. Conclusions and Relevance: This cohort study found that more than 80% of individuals with hypertensive disorders of pregnancy had ongoing hypertension after hospital discharge, with approximately 14% developing severe hypertension. These data support the critical role of remote BP monitoring programs and highlight the need for improved tools for risk stratification and consideration of liberalization of thresholds for medication initiation post partum.

An Exploration of Support for Clinical Education Partners.

INTRODUCTION: Effective academic-clinical partnerships require a greater understanding of how academic programs can best support clinical education (CE) faculty. This study aimed to determine resources and support that clinical partners need. REVIEW OF LITERATURE: As the number of physical therapist (PT) programs, cohort sizes, and CE weeks have risen, so has demand for CE sites. Conversely, staffing reductions, increased administrative duties, and rising productivity expectations have decreased the time available for clinical instruction. To promote a successful CE experience, there must be a renewed understanding of CE faculty needs. SUBJECTS: Clinical education faculty affiliated with any of the 8 contributing programs from the Ohio-Kentucky Consortium participated in survey research (n = 24) and subsequent interview (n = 4) and focus group (n = 6) research. METHODS: Constructivist grounded theory design was used to explore the needs of CE faculty. Academic and clinical partners developed the initial survey and used survey results to establish interview questions. The investigators iteratively assessed data saturation and clarity of results of coded survey, interview, and focus group data to determine whether the study's aims of identifying CE faculty needs had been met. RESULTS: The aggregated results yielded 5 main themes of Director of Clinical Education support for CE faculty needs: student readiness for CE experience; effective academic-clinical partner communication; collaborative management of exceptional students; judicious standardization of CE processes; and provision of CE faculty development resources. DISCUSSION AND CONCLUSION: Clinical education faculty have noted challenges that affect their ability to mentor students. They want academic programs to be more collaborative and proactive with communication, resources, and support. Future research should address aids and barriers to proactive communication, resource provision, and academic-clinical partner collaboration.

The effect of a neonatal sleep intervention on maternal postpartum hypertension: a randomized trial.

BACKGROUND: In nonpregnant adults, poor sleep is associated with higher blood pressure. Poor sleep is common in the postpartum period and is often attributed to infant caretaking needs. However, its effects on cardiovascular health in individuals with a hypertensive disorder of pregnancy are unknown. OBJECTIVE: This study aimed to determine the effect of a neonatal sleep intervention on maternal postpartum blood pressure in individuals with a hypertensive disorder of pregnancy. STUDY DESIGN: In this single-institution pilot randomized controlled trial from July 2021 to March 2022, 110 individuals with a hypertensive disorder of pregnancy were randomized to receive a neonatal sleep intervention (SNOO responsive bassinet) plus usual care of safe sleep education (n=54) or usual care alone (n=56). Remote follow-up visits were conducted at 1 week, 6 weeks, and 4 months after delivery and involved blood pressure and weights, sleep and mood questionnaires, and self-reported infant and maternal sleep logs. Based on institutional data, the sample size had 80% power to detect a 4.5-mm Hg difference in the primary outcome of mean arterial pressure at 6 weeks after delivery. RESULTS: Baseline characteristics were similar between the arms. At 1 week after delivery, the intervention arm had lower mean arterial pressure and less antihypertensive medication use than the control arm (99±10 vs 103±7 mm Hg [P=.04] and 23% vs 35% [P=.15], respectively). At 6 weeks after delivery, mean arterial pressure was similar between arms (93±8 vs 94±8 mm Hg; P=.54), but there was a lower rate of antihypertensive use in the intervention arm (15% vs 26%; P=.19). Scores from maternal sleep and mood questionnaires at 6 weeks after delivery and self-reported infant and maternal sleep duration at 6 weeks and 4 months after delivery were similar between arms (P>.05). CONCLUSION: The SNOO responsive bassinet as a neonatal sleep intervention did not result in improved mean arterial pressure at 6 weeks after delivery after hypertensive disorders of pregnancy.

Obstetric operating room staffing and operating efficiency using queueing theory.

INTRODUCTION: Strategies to achieve efficiency in non-operating room locations have been described, but emergencies and competing priorities in a birth unit can make setting optimal staffing and operation benchmarks challenging. This study used Queuing Theory Analysis (QTA) to identify optimal birth center operating room (OR) and staffing resources using real-world data. METHODS: Data from a Level 4 Maternity Center (9,626 births/year, cesarean delivery (CD) rate 32%) were abstracted for all labor and delivery operating room activity from July 2019-June 2020. QTA has two variables: Mean Arrival Rate, λ and Mean Service Rate µ. QTA formulas computed probabilities: P0 = 1-(λ/ µ) and Pn = P0 (λ/µ)n where n = number of patients. P0…n is the probability there are zero patients in the queue at a given time. Multiphase multichannel analysis was used to gain insights on optimal staff and space utilization assuming a priori safety parameters (i.e., 30 min decision to incision in unscheduled CD; ≤ 5 min for emergent CD; no greater than 8 h for nil per os time). To achieve these safety targets, a < 0.5% probability that a patient would need to wait was assumed. RESULTS: There were 4,017 total activities in the operating room and 3,092 CD in the study period. Arrival rate λ was 0.45 (patients per hour) at peak hours 07:00-19:00 while λ was 0.34 over all 24 h. The service rate per OR team (µ) was 0.87 (patients per hour) regardless of peak or overall hours. The number of server teams (s) dedicated to OR activity was varied between two and five. Over 24 h, the probability of no patients in the system was P0 = 0.61, while the probability of 1 patient in the system was P1 = 0.23, and the probability of 2 or more patients in the system was P≥2 = 0.05 (P3 = 0.006). However, between peak hours 07:00-19:00, λ was 0.45, µ was 0.87, s was 3, P0 was 0.48; P1 was 0.25; and P≥2 was 0.07 (P3 = 0.01, P4 = 0.002, P5 = 0.0003). CONCLUSION: QTA is a useful tool to inform birth center OR efficiency while upholding assumed safety standards and factoring peaks and troughs of daily activity. Our findings suggest QTA is feasible to guide staffing for maternity centers of all volumes through varying model parameters. QTA can inform individual hospital-level decisions in setting staffing and space requirements to achieve safe and efficient maternity perioperative care.

Factors associated with postpartum initiation of anti-hypertensive medication after hospital discharge among individuals with hypertensive disorders of pregnancy in a remote monitoring program.

Importance: Following a hypertensive disorder of pregnancy, hypertension can worsen in the postpartum period following hospital discharge. Risk factors for hypertension exacerbation and associated outcomes have not been well characterized. Objective: We sought to identify risk factors and characterize outcomes for individuals requiring initiation of anti-hypertensive medication following hospital discharge postpartum through our hospital system's remote blood pressure management program. Design: We performed a cohort study of individuals delivered between 9/2019-6/2021 and enrolled in our remote blood pressure monitoring program, which utilizes standardized protocols for anti-hypertensive medication initiation postpartum. Setting: Postpartum unit at a referral hospital. Participants: Population-based sample of individuals with a hypertensive disorder of pregnancy (HDP, preeclampsia or gestational hypertension) and no pre-pregnancy hypertension. Exposure: Anti-hypertensive medication initiation timing: no anti-hypertensive medications, initiation prior to hospital discharge postpartum, and initiation after hospital discharge postpartum. Main outcomes: Postpartum readmission and emergency room visits. Results: Of 2,705 individuals in our cohort, 1,458 (54%) required no anti-hypertensive medications postpartum, 637 individuals (24%) were discharged on anti-hypertensive medications, and 610 (23%) required initiation of anti-hypertensive agents after discharge. Utilizing an inpatient threshold of ≥ 150/100 mmHg in line with current obstetric guidelines for medication initiation postpartum fails to identify 385 (63%) of individuals who required medication initiation after discharge. These individuals had higher home blood pressures, increased odds of Emergency Room visits [aOR 2.22 (95%CI 1.65-2.98)] and hospital readmissions postpartum [aOR 5.73 (95%CI 3.72-8.82)] compared with individuals discharged on no medications. Conclusions and Relevance: Over 20% of individuals with hypertensive disorders of pregnancy required initiation of anti-hypertensive medications after hospital discharge. Current blood pressure guidelines for medication initiation fail to identify the majority of these individuals during delivery hospitalization. These data support the critical role of remote blood pressure monitoring programs and highlight the need for improved tools for risk strati cation and liberalization of thresholds for medication initiation postpartum.

Perceptions and knowledge of COVID-19 vaccine safety and efficacy among vaccinated and non-vaccinated obstetric healthcare workers.

The COVID-19 vaccines are highly effective in preventing COVID-19 illness; however, pregnant people were not included in the original COVID-19 vaccine trials, with resultant conflicting recommendations from health organizations regarding vaccinations for this high-risk population. Pregnant and lactating healthcare workers (HCWs), along with people planning a pregnancy, identified as "obstetric HCWs" in our study, were among the first to make decisions regarding vaccinating themselves against COVID-19. Given that HCWs are key sources of information and access to vaccinations, this study was conducted to understand the perceptions and knowledge of obstetric HCWs regarding the COVID-19 vaccine. An electronic survey to HCWs at a tertiary care institution in Pittsburgh, PA identified 83 obstetric HCWs, of which 65 (78.3%) received at least one dose of the either the Pfizer or Moderna COVID-19 vaccine, and 18 (21.7%) had not received any doses of vaccine. Pregnancy status influenced more people not to receive than to receive the vaccine. We found that both vaccinated and non-vaccinated obstetric HCWs had accurate knowledge regarding the COVID-19 vaccine. However, compared to non-vaccinated obstetric HCWs, vaccinated obstetric HCWs tended to endorse beliefs regarding herd immunity, believed they had a higher chance of acquiring COVID-19, and felt that the COVID-19 vaccine was safe for fetuses and people who were pregnant, lactating, breastfeeding, or planning a pregnancy. This study offers insight into obstetric individuals' perceptions and knowledge of the COVID-19 vaccine, and highlights areas where additional education and outreach may help obstetric individuals make informed decisions on receiving the COVID-19 vaccine.

Neighborhood disadvantage and the racial disparity in postpartum hypertension.

BACKGROUND: Postpartum hypertension is the leading cause of postpartum readmission and has long-lasting cardiovascular effects. Black patients have higher incidence rates of hypertensive disorders after delivery and subsequent severe maternal morbidity. Neighborhood advantage, a marker of social determinants of health, has not been studied concerning postpartum hypertension. Moreover, the interplay between race and neighborhood advantage and their effect on postpartum hypertension have not been previously explored. OBJECTIVE: This study aimed to evaluate the association between neighborhood-level social determinants of health and postpartum hypertension and explore whether these factors explain previously documented racial disparities. STUDY DESIGN: This study included a retrospective cohort of people enrolled in a remote monitoring program of postpartum hypertension at the time of delivery within 1 health network from March 2019 to September 2021. Patients were eligible for enrollment after a diagnosis of hypertensive disorder during pregnancy or delivery. We further limited the cohort to self-reported Black and White patients with blood pressures recorded at 3 weeks and 6 weeks postpartum. The neighborhood advantage for each person at the time of delivery was classified using the area deprivation index, an accepted surrogate of social determinants of health and our primary exposure. The secondary exposure was self-reported race. Study outcomes of interest were hypertensive status (stage 1 hypertension: ≥130 to 139/80 to 89 mm Hg; stage 2 hypertension: ≥140/90 mm Hg) at 3 and 6 weeks after delivery. In addition, hypertensive status by neighborhood area deprivation index using logistic regression was molded. In secondary analyses, a case-control cohort matched on the area deprivation index was created, and conditional logistic regression was used to evaluate race. Finally, mixed-effects models modeling hypertension by race and clustering within the area deprivation index were used. RESULTS: Of 4193 people enrolled, 2722 were Black or White and had blood pressure data recorded at 3 weeks after delivery, and 1126 had blood pressure data recorded at 6 weeks after delivery. After accounting for prenatal body mass index, smoking status, type of hypertension, and antihypertensives prescribed at discharge, persons living in the most disadvantaged neighborhoods were twice as likely (adjusted odds ratio, 2.03; 95% confidence interval, 1.53-2.69) to develop stage 2 hypertension at 21 days after delivery and 1.67 times more likely (95% confidence interval, 1.06-2.64) to develop stage 2 hypertension at 6 weeks after delivery than persons living in the most advantaged neighborhoods. Both associations were attenuated after adjusting for race. When people with stage 2 hypertension were matched on area deprivation index with normotensive counterparts, Black patients were still 3 to 4 times more likely to develop stage 2 hypertension at 3 (adjusted odds ratio, 3.00; 95% confidence interval, 1.95-4.63) and 6 (adjusted odds ratio, 4.61; 95% confidence interval, 2.05-10.36) weeks after delivery. This association remained after clustering within a neighborhood at 3 (adjusted odds ratio, 3.12; 95% confidence interval, 2.41-4.06) and 6 (adjusted odds ratio, 2.99; 95% confidence interval, 1.96-4.54) weeks after delivery. There was no significant difference in stage 1 hypertension. CONCLUSION: Neighborhood advantage was associated with the development of persistent hypertension at 3 and 6 weeks after delivery. This association did not explain the racial disparity in sustained high blood pressure.

Implementation of a universal postpartum blood pressure monitoring program: feasibility and outcomes.

BACKGROUND: New-onset postpartum preeclampsia has a higher risk of maternal morbidity and mortality than preeclampsia with antepartum onset, underscoring the need for earlier identification of elevated blood pressure among patients with this condition. Given the decrease in healthcare engagement, which is typical of the postpartum period, new-onset postpartum hypertension often goes unrecognized. Currently, there are no recommendations for universal postpartum blood pressure surveillance in women without hypertensive disorders of pregnancy. With the shift to telemedicine because of the COVID-19 pandemic, our institution's approach was to distribute blood pressure cuffs to women receiving any portion of their prenatal care virtually, thus also providing access to an opportunity for blood pressure measurement during the postpartum period for all women. OBJECTIVE: To explore the feasibility of a patient-driven universal postpartum home blood pressure monitoring program in women without a previous diagnosis of a hypertensive disorder. STUDY DESIGN: This was a prospective observational study of all postpartum women who were discharged from our institution from July 2020 through June 2021 and who were not previously identified to have hypertension. A clinical algorithm was developed and followed. All the women received discharge educational materials and were called at a 1-week interval by a nurse to review blood pressure and preeclampsia symptoms. The maternal demographics and delivery outcomes were recorded. RESULTS: Of the 10,092 deliveries during the study period, 5959 (59%) were successfully contacted. 352 were excluded, as they did not deliver at the primary hospital; 1052 (18%) had a previous hypertensive disorder of pregnancy diagnosis; 1522 (26%) did not have a blood pressure cuff; and 1841 (31%) planned to take their blood pressure at a later time. Precautions and blood pressure parameters were given to this last group. Of the remaining 1192, 222 (19%) had an initial elevated blood pressure. Of these, 98 had a second elevated blood pressure on recheck; 17 were referred to the emergency room for evaluation, with 8 being diagnosed with severe preeclampsia; and the remainder were recommended to follow with their obstetrical provider and enrolled in our institution's remote blood pressure management program. Of the 1192 women, 8% potentially had a new diagnosis of a hypertensive disorder of pregnancy, with 0.7% having severe hypertension. Women with elevated blood pressures were more likely to be of non-Hispanic Black race and have a higher early pregnancy body mass index than those without elevated blood pressures. CONCLUSION: Our study indicates that a patient-driven postpartum blood pressure monitoring program is feasible and may be incorporated using existing resources. In addition, our findings suggest that the incidence of new-onset postpartum hypertensive disorders of pregnancy may be higher than previously assessed in retrospective cohorts. Thus, there may be a role for closer surveillance of all women with patient-driven home blood pressure monitoring, particularly those with risk factors or in the setting of limited resources.

Mobile Remote Monitoring of Intimate Partner Violence Among Pregnant Patients During the COVID-19 Shelter-In-Place Order: Quality Improvement Pilot Study.

BACKGROUND: Intimate partner violence (IPV) is one of the leading causes of pregnancy-related death. Prenatal health care providers can offer critical screening and support to pregnant people who experience IPV. During the COVID-19 shelter-in-place order, mobile apps may offer such people the opportunity to continue receiving screening and support services. OBJECTIVE: We aimed to examine cases of IPV that were reported on a prenatal care app before and during the implementation of COVID-19 shelter-in-place mandates. METHODS: The number of patients who underwent voluntary IPV screening and the incidence rate of IPV were determined by using a prenatal care app that was disseminated to patients from a single, large health care system. We compared the IPV screening frequencies and IPV incidence rates of patients who started using the app before the COVID-19 shelter-in-place order, to those of patients who started using the app during the shelter-in-place order. RESULTS: We found 552 patients who started using the app within 60 days prior to the enforcement of the shelter-in-place order, and 407 patients who used the app at the start of shelter-in-place enforcement until the order was lifted. The incidence rates of voluntary IPV screening for new app users during the two time periods were similar (before sheltering in place: 252/552, 46%; during sheltering in place: 163/407, 40%). The overall use of the IPV screening tool increased during the shelter-in-place order. A slight, nonsignificant increase in the incidence of physical, sexual, and psychological violence during the shelter-in-place order was found across all app users (P=.56). Notably, none of the patients who screened positively for IPV had mentions of IPV in their medical charts. CONCLUSIONS: App-based screening for IPV is feasible during times when in-person access to health care providers is limited. Our results suggest that the incidence of IPV slightly increased during the shelter-in-place order. App-based screening may also address the needs of those who are unwilling or unable to share their IPV experiences with their health care provider.

Racial Differences in Postpartum Blood Pressure Trajectories Among Women After a Hypertensive Disorder of Pregnancy.

Importance: Maternal morbidity and mortality are increasing in the United States, most of which occur post partum, with significant racial disparities, particularly associated with hypertensive disorders of pregnancy. Blood pressure trajectory after a hypertensive disorder of pregnancy has not been previously described. Objectives: To describe the blood pressure trajectory in the first 6 weeks post partum after a hypertensive disorder of pregnancy and to evaluate whether blood pressure trajectories differ by self-reported race. Design, Setting, and Participants: This prospective cohort study included deliveries between January 1, 2018, and December 31, 2019. Women with a clinical diagnosis of a hypertensive disorder of pregnancy were enrolled in a postpartum remote blood pressure monitoring program at the time of delivery and were followed up for 6 weeks. Statistical analysis was performed from April 6 to 17, 2020. Main Outcomes and Measures: Mixed-effects regression models were used to display blood pressure trajectories in the first 6 weeks post partum. Results: A total of 1077 women were included (mean [SD] age, 30.2 [5.6] years; 804 of 1017 White [79.1%] and 213 of 1017 Black [20.9%]). Systolic and diastolic blood pressures were found to decrease rapidly in the first 3 weeks post partum, with subsequent stabilization (at 6 days post partum: mean [SD] peak systolic blood pressure, 146 [13] mm Hg; mean [SD] peak diastolic blood pressure, 95 [10] mm Hg; and at 3 weeks post partum: mean [SD] peak systolic blood pressure, 130 [12] mm Hg; mean [SD] peak diastolic blood pressure, 85 [9] mm Hg). A significant difference was seen in blood pressure trajectory by race, with both systolic and diastolic blood pressure decreasing more slowly among Black women compared with White women (mean [SD] peak systolic blood pressure at 1 week post partum: White women, 143 [14] mm Hg vs Black women, 146 [13] mm Hg; P = .01; mean [SD] peak diastolic blood pressure at 1 week post partum: White women, 92 [9] mm Hg vs Black women, 94 [9] mm Hg; P = .02; and mean [SD] peak systolic blood pressure at 3 weeks post partum: White women, 129 [11] mm Hg vs Black women, 136 [15] mm Hg; P < .001; mean [SD] peak diastolic blood pressure at 3 weeks post partum: White women, 84 [8] mm Hg vs Black women, 91 [13] mm Hg; P < .001). At the conclusion of the program, 126 of 185 Black women (68.1%) compared with 393 of 764 White women (51.4%) met the criteria for stage 1 or stage 2 hypertension (P < .001). Conclusions and Relevance: This study found that, in the postpartum period, blood pressure decreased rapidly in the first 3 weeks and subsequently stabilized. The study also found that, compared with White women, Black women had a less rapid decrease in blood pressure, resulting in higher blood pressure by the end of a 6-week program. Given the number of women with persistent hypertension at the conclusion of the program, these findings also appear to support the importance of ongoing postpartum care beyond the first 6 weeks after delivery.

A Postpartum Remote Hypertension Monitoring Protocol Implemented at the Hospital Level.

OBJECTIVE: To evaluate the feasibility, acceptability, and compliance of a remote blood pressure monitoring protocol implemented as a quality improvement measure at the hospital level for management of hypertension in postpartum women after hospital discharge. METHODS: This is an ongoing quality improvement project that included women admitted to the postpartum unit of a single tertiary care hospital. We designed nursing call center-driven blood pressure management and treatment algorithms, which were initiated after hospital discharge until 6 weeks postpartum. Women are eligible to participate if they have a diagnosis of chronic hypertension, superimposed preeclampsia, gestational hypertension, preeclampsia, or postpartum hypertension and have access to a text messaging-enabled smartphone device. After identification by an obstetric care provider, women are enrolled into the program, which is automatically indicated in the electronic medical record. Maternal, obstetric, and sociodemographic data were obtained from the electronic medical record. RESULTS: Between February 2018 and January 2019, we enrolled 499 patients. Here we report on the first 409 enrolled patients. Participants include 168 (41%) with gestational hypertension, 179 (44%) with preeclampsia with no history of chronic hypertension, 49 (12%) with chronic hypertension with superimposed preeclampsia, and 13 (3%) with postpartum preeclampsia. One hundred seventy-one (42%) participants had antihypertensives initiated or titrated through the program. Three hundred forty women (83%) continued the program beyond 3 weeks postpartum, and 360 (88%) attended an in-person 6-week postpartum visit. Two hundred thirty-five out of 250 women who completed a postprogram survey (94%) reported satisfaction with the program. CONCLUSION: In this study, we detail results from an ongoing remote blood pressure monitoring program. We demonstrate high compliance, retention, and patient satisfaction with the program. This is a feasible, scalable remote monitoring program connected to the electronic medical record.

Announcements Versus Conversations to Improve HPV Vaccination Coverage: A Randomized Trial.

OBJECTIVE: Improving provider recommendations is critical to addressing low human papillomavirus (HPV) vaccination coverage. Thus, we sought to determine the effectiveness of training providers to improve their recommendations using either presumptive "announcements" or participatory "conversations." METHODS: In 2015, we conducted a parallel-group randomized clinical trial with 30 pediatric and family medicine clinics in central North Carolina. We randomized clinics to receive no training (control), announcement training, or conversation training. Announcements are brief statements that assume parents are ready to vaccinate, whereas conversations engage parents in open-ended discussions. A physician led the 1-hour, in-clinic training. The North Carolina Immunization Registry provided data on the primary trial outcome: 6-month coverage change in HPV vaccine initiation (≥1 dose) for adolescents aged 11 or 12 years. RESULTS: The immunization registry attributed 17 173 adolescents aged 11 or 12 to the 29 clinics still open at 6-months posttraining. Six-month increases in HPV vaccination coverage were larger for patients in clinics that received announcement training versus those in control clinics (5.4% difference, 95% confidence interval: 1.1%-9.7%). Stratified analyses showed increases for both girls (4.6% difference) and boys (6.2% difference). Patients in clinics receiving conversation training did not differ from those in control clinics with respect to changes in HPV vaccination coverage. Neither training was effective for changing coverage for other vaccination outcomes or for adolescents aged 13 through 17 (n = 37 796). CONCLUSIONS: Training providers to use announcements resulted in a clinically meaningful increase in HPV vaccine initiation among young adolescents.

Organizational correlates of adolescent immunization: findings of a state-wide study of primary care clinics in North Carolina.

OBJECTIVE: To analyze organizational correlates of immunization coverage among adolescents served by high-volume primary care providers in North Carolina. METHODS: We randomly selected 91 clinics with at least 200 active records for patients ages 11-18 in the North Carolina Immunization Registry. For the 105,121 adolescents served by these clinics, we obtained immunization status for 6 vaccines, including human papillomavirus (HPV) vaccine (females only); meningococcal conjugate; and tetanus, diphtheria, and pertussis booster (Tdap). RESULTS: Clinics specializing in pediatrics had higher coverage for meningococcal vaccine (OR=1.79, 95% CI: 1.25-2.55), Tdap vaccine (OR=1.22, 95% CI: 1.00-1.50), and childhood vaccines. However, pediatric clinics had lower coverage for HPV vaccine initiation (OR=0.70, 95% CI: 0.52-0.94). Other correlates, which varied by vaccine, included policies related to vaccine documentation and the age at which clinics recommended vaccines. CONCLUSION: Overall, adolescents were more likely to receive vaccines, except HPV vaccine, if they attended a pediatric clinic with supportive clinical policies.

The HPV vaccine: are dosing recommendations being followed?

The aims of this study were to determine the percentage of females who after initiating the human papillomavirus (HPV) vaccine series, both completed it and completed it on-time, as well as to examine factors associated with series completion and on-time completion. Using data from the North Carolina Immunization Registry, of 138,823 females analyzed, 55% completed the series, and 28% completed it on-time. Over 83% of those who initiated the vaccine series in 2006 completed it by the final study date, as compared to 32% of those who initiated the vaccine in 2009. On-time dosing rates, however, are declining, and have been hovering at 25% for the last two years of the study. Factors such as African-American race and public funding were significantly associated with lower rates of on-time dosing as well as series completion when compared to White race and private funding, respectively. Among girls and young women who initiate the HPV vaccination series, overall completion rates are low, but if given enough time most of those who begin the series will complete it. Our results suggest that strategies to improve the timely completion of the HPV vaccination series may be needed.
