RESUMEN
Importance: Maternal emergency department (ED) use before or during pregnancy is associated with worse obstetrical outcomes, for reasons including preexisting medical conditions and challenges in accessing health care. It is not known whether maternal prepregnancy ED use is associated with higher use of the ED by their infant. Objective: To study the association between maternal prepregnancy ED use and risk of infant ED use in the first year of life. Design, Setting, and Participants: This population-based cohort study included all singleton livebirths in all of Ontario, Canada, from June 2003 to January 2020. Exposures: Any maternal ED encounter within 90 days preceding the start of the index pregnancy. Main Outcomes and Measures: Any infant ED visit up to 365 days after the index birth hospitalization discharge date. Relative risks (RR) and absolute risk differences (ARD) were adjusted for maternal age, income, rural residence, immigrant status, parity, having a primary care clinician, and number of prepregnancy comorbidities. Results: There were 2â¯088â¯111 singleton livebirths; the mean (SD) maternal age was 29.5 (5.4) years, 208â¯356 (10.0%) were rural dwelling, and 487â¯773 (23.4%) had 3 or more comorbidities. Among singleton livebirths, 206â¯539 mothers (9.9%) had an ED visit within 90 days before the index pregnancy. ED use in the first year of life was higher among infants whose mother had visited the ED before pregnancy (570 per 1000) vs those whose mother had not (388 per 1000) (RR, 1.19 [95% CI, 1.18-1.20]; ARD, 91.1 per 1000 [95% CI, 88.6-93.6 per 1000]). Compared with mothers without a prepregnancy ED visit, the RR of infant ED use in the first year was 1.19 (95% CI, 1.18-1.20) if its mother had 1 prepregnancy ED visit, 1.18 (95% CI, 1.17-1.20) following 2 visits, and 1.22 (95% CI, 1.20-1.23) after at least 3 maternal visits. A low-acuity maternal prepregnancy ED visit was associated with an adjusted odds ratio (aOR) of 5.52 (95% CI, 5.16-5.90) for a low-acuity infant ED visit, which was numerically higher than the pairing of a high-acuity ED use between mother and infant (aOR, 1.43, 95% CI, 1.38-1.49). Conclusions and Relevance: In this cohort study of singleton livebirths, prepregnancy maternal ED use was associated with a higher rate of ED use by the infant in the first year of life, especially for low-acuity ED use. This study's results may suggest a useful trigger for health system interventions aimed at reducing some ED use in infancy.

OBJECTIVE: To evaluate the use of point-of-care ultrasound (POCUS) for the assessment of patients experiencing first-trimester bleeding or abdominal pain by family physicians working in family medicine clinics following first-trimester POCUS training and certification. DESIGN: Multisite, retrospective chart review. SETTING: Two hospital-affiliated academic family medicine clinics in Toronto, Ont. PARTICIPANTS: Twelve family physicians who completed a first-trimester POCUS training and certification course. MAIN OUTCOME MEASURES: The primary outcome was the proportion of family physicians using POCUS during their evaluations of patients in the first trimester of pregnancy in the 6 months following the FPs' successful completion of the Family Medicine Obstetrical Ultrasound (FaMOUS) course. Secondary outcomes included indications for POCUS use, diagnostic accuracy of POCUS compared with radiologist-interpreted ultrasound, pregnancy outcomes, and emergency department visits within 10 days of the index family medicine clinic visit. RESULTS: Of the 12 certified family physicians, 7 (58.3%) used POCUS during their assessments of first-trimester patients during the study period. The FPs used POCUS with 56 patients for the following indications: 11 (19.6%) had only vaginal bleeding, 5 (8.9%) had only abdominal pain, and 8 (14.3%) had both vaginal bleeding and abdominal pain; the indication for 32 patients (57.1%) was unclear. Forty-six patients (82.1%) underwent a subsequent radiologist-interpreted ultrasound within 10 days of the index POCUS test. Compared with radiologist-interpreted ultrasound, POCUS had a sensitivity of 91.3% (95% CI 79.2% to 97.6%) for documenting intrauterine pregnancy and a sensitivity of 81.4% (95% CI 66.6% to 91.6%) for documenting the presence of fetal cardiac activity. CONCLUSION: Following a first-trimester POCUS certification course, family physicians used POCUS for the assessment of first-trimester patients with varying frequency and for indications other than vaginal bleeding or abdominal pain. Further study is needed to assess the clinical impact of office-based POCUS, unforeseen barriers and facilitators to its use, and patient and provider preferences.

Importance: Emergency department (ED) use during pregnancy may be associated with worse obstetrical outcomes, possibly because of differences in access to health care. It is not known whether ED use before pregnancy is associated with serious adverse maternal and perinatal outcomes. Objective: To study the association between prepregnancy ED use and adverse maternal and perinatal outcomes. Design, Setting, and Participants: This population-based cohort study was conducted in Ontario, Canada, and included all livebirths and stillbirths from April 2003 to January 2020. Exposures: Main exposure was any ED encounter within 90 days preceding the start of the index pregnancy. Main Outcomes and Measures: Primary outcome was a composite of severe maternal morbidity (SMM) from 20 weeks' gestation to 42 days' post partum. Secondary outcomes included severe neonatal morbidity (SNM) from 0 to 27 days, neonatal death, and stillbirth. Relative risks (RRs) were adjusted for maternal age, income, and rurality. Results: Of 2â¯130â¯245 births, there were 2â¯119â¯335 livebirths (99.5%) and 10â¯910 stillbirths (0.5%). The mean (SD) maternal age was 29.6 (5.4) years, 212â¯478 (9.9%) were rural dwelling, and 498â¯219 (23%) had 3 or more comorbidities. Among all births, 218â¯011 (9.7%) had a prepregnancy ED visit. The rate of SMM was higher among women with a prepregnancy ED visit than those without (22.3 vs 16.5 per 1000 births), with an RR of 1.34 (95% CI, 1.30-1.38) and an adjusted RR (aRR) of 1.37 (95% CI, 1.33-1.42). Compared with no prepregnancy ED visit, the aRR was higher in those with 1 (1.29; 95% CI, 1.24-1.34), 2 (1.51; 95% CI, 1.42-1.61), and 3 or more (1.74; 95% CI, 1.61-1.90) ED visits. Prepregnancy ED visits for a hematological (aRR, 13.60; 95% CI, 10.48-17.64), endocrine (aRR, 4.96; 95% CI, 3.72-6.62), and circulatory (aRR, 2.27; 95% CI, 1.68-3.07) conditions were associated with the highest aRRs for SMM. The rate of SNM was higher among newborns whose mother visited the ED within 90 days before pregnancy (68.2 vs 55.4 per 1000 births; aRR, 1.24; 95% CI, 1.22-1.26) as was the risk of neonatal death (aRR, 1.26; 95% CI, 1.16-1.37) and stillbirth (aRR, 1.18; 95% CI, 1.11-1.25). Conclusions and Relevance: In this study, ED use was common before pregnancy. These findings suggest that ED use may not only reflect a woman's access to prepregnancy care but also higher future risk of severe maternal and perinatal morbidity, potentially offering a useful trigger for health system interventions to decrease adverse pregnancy outcomes.

BACKGROUND: There is a paucity of effective management strategies to prevent prolonged symptoms following mild traumatic brain injury (mTBI), and emerging evidence suggesting possible benefits of exercise. The objective of this trial was to determine whether adult patients presenting to the emergency department (ED) with a diagnosis of acute mTBI prescribed light exercise were less likely to develop persistent postconcussion symptoms (PCS). METHODS: This was a randomized controlled trial conducted in three Canadian EDs. Consecutive, adult (18-64 years) ED patients with an mTBI sustained within the preceding 48 hours were eligible for enrollment. The intervention group received discharge instructions prescribing 30 minutes of daily light exercise, and the control group was given standard mTBI instructions advising gradual return to exercise following symptom resolution. The primary outcome was the proportion of patients with PCS at 30 days, defined as the presence of three or more symptoms on the Rivermead Post-concussion Symptoms Questionnaire (RPQ). RESULTS: A total of 367 patients were enrolled (control group, n = 184; intervention, n = 183). Median age was 32 years and 201 (57.6%) were female. There was no difference in the proportion of patients with PCS at 30 days (control, 13.4% vs intervention, 14.6%; ∆1.2%, 95% confidence interval [CI] = -6.2 to 8.5). There were no differences in median change of RPQ scores, median number of return health care provider visits, median number of missed school or work days, or unplanned return ED visits within 30 days. Participants in the control group reported fewer minutes of light exercise at 7 days (30 vs 35; ∆5, 95% CI = 2 to 15). CONCLUSION: In this trial of prescribed early light exercise for acute mTBI, there were no differences in recovery or health care utilization outcomes. Results suggest that early light exercise may be encouraged as tolerated at ED discharge following mTBI, but this guidance is not sufficient to prevent PCS.

BACKGROUND: Peripregnancy emergency department use may be common, but data specific to health care systems like that in Canada are lacking. As prior research was limited to livebirths, omitting pregnancies ending in miscarriage or induced abortion, the current study quantified and characterized emergency department use among women in Ontario with a recognized pregnancy. METHODS: This retrospective population-based cohort study included all recognized pregnancies among Ontario residents aged 10-55 years with an estimated date of conception between Apr. 1, 2002, and Mar. 31, 2017. We defined peripregnancy emergency department use as any emergency department visit during pregnancy or within 42 days after pregnancy. We used modified Poisson regression with a robust error variance to generate relative risks (RRs) and 95% confidence intervals (CIs) for the outcome of any peripregnancy emergency department use in association with maternal age, parity, residential income quintile, location of residence, immigrant status, antenatal care provider and number of comorbidities within 120 days before the clinical start of the pregnancy (expressed as total number of Aggregated Diagnosis Groups [ADGs] obtained with the Johns Hopkins Adjusted Clinical Group System). All RRs, except for number of comorbidities, were further adjusted for number of ADGs. RESULTS: Peripregnancy emergency department use occurred in 1 075 991 (39.4%) of 2 728 236 recognized pregnancies, including 35.8% of livebirths, 47.3% of stillbirths, 73.7% of miscarriages and 84.8% of threatened abortions. A peripregnancy emergency department visit was more likely among women who were less than 25 years of age (adjusted RR 1.16, 95% CI 1.16-1.17), were nulliparous (adjusted RR 1.13, 95% CI 1.13-1.13), resided in the lowest income quintile area (adjusted RR 1.16, 95% CI 1.15-1.16) or in a rural area (adjusted RR 1.50, 95% CI 1.50-1.51), were Canadian-born (adjusted RR 1.22, 95% CI 1.22-1.23), were not seen by an obstetrician (adjusted RR 1.66, 95% CI 1.54-1.80) or had a greater number of ADGs. Emergency department use peaked in the first trimester and in the first week postpartum. Compared to women residing in urban areas, those residing in rural areas had an odds ratio (OR) of 3.44 (95% CI 3.39-3.49) for 3 or more emergency department visits. Women with 3-4 (OR 1.99, 95% CI 1.97-2.01), 5-6 (OR 3.55, 95% CI 3.49-3.61), or 7 or more (OR 7.59, 95% CI 7.39-7.78) prepregnancy comorbidities were more likely to have 3 or more peripregnancy emergency department visits than were those with 2 or fewer comorbidities. INTERPRETATION: Peripregnancy emergency department use occurred in nearly 40% of pregnancies, notably in the first trimester and early in the postpartum period. Efforts are needed to streamline rapid access to ambulatory obstetric care during these peak periods, when women are susceptible to miscarriage or a complication after a livebirth.

OBJECTIVES: It is estimated that 15%-25% of patients with a mild traumatic brain injury (MTBI) diagnosed in the emergency department (ED) will develop postconcussive syndrome. The objective of this study was to determine if patients randomized to graduated return to usual activity discharge instructions had a decrease in their Post-Concussion Symptom Score (PCSS) 2 weeks after MTBI compared to patients who received usual care MTBI discharge instructions. METHODS: This was a pragmatic, randomized trial of adult (18-64 years) patients of an academic ED (annual census 60,000) diagnosed with MTBI occurring within 24 hours of ED visit. The intervention group received cognitive rest and graduated return to usual activity discharge instructions, and the control group received usual care discharge instructions that did not instruct cognitive rest or graduated return. Patients were contacted by text message or phone 2 and 4 weeks post-ED discharge and asked to complete the PCSS, a validated, 22-item questionnaire, to determine if there was a change in their symptoms. Secondary outcomes included change in PCSS at 4 weeks, number follow-up physician visits, and time off work/school. RESULTS: A total of 118 patients were enrolled in the study (58 in the control group and 60 in the intervention). The mean (±SD) age was 35.2 (±13.7) years and 43 (36.4%) were male. There was no difference with respect to change in PCSS at 2 weeks (10.5 vs. 12.8; ∆2.3, 95% confidence interval [CI] = 7.0 to 11.7) and 4 weeks post-ED discharge (21.1 vs 18.3; ∆2.8, 95% CI = 6.9 to 12.7) for the intervention and control groups, respectively. The number of follow-up physician visits and time off work/school were similar when the groups were compared. Thirty-eight (42.2%) and 23 (30.3%) of patients in this cohort had ongoing MTBI symptoms (PCSS > 20) at 2 and 4 weeks, respectively. CONCLUSIONS: Results from this study suggest graduated return to usual activity discharge instructions do not impact rate of resolution of MTBI symptoms 2 weeks after ED discharge. Given that patients continue to experience symptoms 2 and 4 weeks after MTBI, more investigation is needed to determine how best to counsel and treat patients with postconcussive symptoms.
