A retrospective review of serious infections in febrile infants 0–90 days old

Background: Fever without source in infants is a common clinical problem that accounts for many ambulatory care visits and hospitalisations. Currently, there is no reliable method of identifying those at risk of serious infection (SI). Objective: The goal of this study was to determine the incidence and identify the predictors of SI in febrile infants who presented to the emergency department (ED). Methods: This was a single-centre retrospective cohort study of children presenting to a Singapore tertiary hospital paediatric unit between 1 July 2018 and 31 December 2018. Children were included if they were aged 0–90 days and presented to the ED with a fever. SI was defined as urinary tract infection (UTI), sepsis, bacteraemia, meningitis (viral and bacterial), enterocolitis, osteomyelitis, abscess or pneumonia. Results: Of the 659 infants, 161 (24.4%) were diagnosed with SI. Meningitis (49.7%) was the most common SI, followed by UTI (45.3%), enterocolitis (5.6%), sepsis (3.1%) and bacteraemia (2.5%). Factors significantly associated with SI were aged 29–60 days, male sex, Severity Index Score (SIS) <10, absolute neutrophil counts >10×109/L, C-reactive protein (CRP) >20 mg/L and procalcitonin >0.5 ng/mL. Multivariate analysis entering all these items retained only male sex, SIS <10 and CRP >20. Conclusion: Among hospitalised infants aged 0–90 days, the incidence of SI was 24.4%, and invasive bacterial infection was 0.6%. Meningitis was the most common SI followed by UTI. SIS and CRP can be used to predict SI in infants <90 days old.

Telehealth Attitudes, Training, and Preparedness Among First-Year Internal Medicine Residents in the COVID-19 Era.

Introduction: Telehealth, especially the use of real-time video and phone visits in ambulatory care, is increasingly important in the wake of the COVID-19 pandemic. The current state of internal medicine (IM) interns' telehealth training at the start of residency is unknown. Objective: To characterize the attitudes, training, and preparedness of IM interns regarding the use of telehealth video and phone visits in ambulatory care. Materials and Methods: We conducted a cross-sectional survey of IM interns at four IM residency programs in the United States in 2020. Results: One hundred fifty-six surveys were analyzed (response rate 82%). Seventy-five percent of interns rated training in the use of real-time video and phone visits for ambulatory care as important or very important. The vast majority received no training (74%) or clinical experience (90% no prior video visits, 81% no prior phone visits) during medical school. More interns believed that primary care may be effectively delivered via video visits compared with phone visits (77% vs. 35%). Most interns (69%) missed clinical time during medical school due to the COVID-19 pandemic; 41% felt that the pandemic negatively affected their ambulatory care preparation. Overall, the majority of interns (58%) felt prepared for primary care; only 12% felt prepared to deliver primary care using either video or phone visits. Conclusions: Although IM interns had favorable attitudes toward video and phone visits, few had training or clinical experience; most felt unprepared. Residency programs may need to close training gaps for current interns in conducting telehealth video and phone visits.

Antibiotic Prescriptions among China Ambulatory Care Visits of Pregnant Women: A Nationwide Cross-Sectional Study.

Background: Antibiotic use in pregnant women at the national level has rarely been reported in China. Objectives: We aimed to investigate antibiotic prescriptions during pregnancy in ambulatory care settings in China. Methods: Data of 4,574,961 ambulatory care visits of pregnant women from October 2014 to April 2018 were analyzed. Percentages of Antibiotic prescriptions by different subgroups and various diagnosis categories and proportions of inappropriate antibiotic prescriptions for different subgroups were estimated. Food and Drug Administration (FDA) pregnancy categories were used to describe the antibiotic prescription patterns. The 95% confidence intervals (CIs) were estimated using the Clopper––Pearson method or Goodman method. Results: Among the 4,574,961 outpatient visits during pregnancy, 2.0% (92,514 visits; 95% CI, 2.0–2.0%) were prescribed at least one antibiotic. The percentage of antibiotic prescriptions for pregnant women aged >40 years was 4.9% (95% CI, 4.7–5.0%), whereas that for pregnant women aged 26–30 years was 1.5% (95% CI, 1.4–1.5%). In addition, percentages of antibiotic prescriptions varied among different trimesters of pregnancy, which were 5.4% (95% CI, 5.3–5.4%) for the visits in the first trimester of pregnancy and 0.5% (95% CI, 0.4–0.5%) in the third trimester of pregnancy. Furthermore, the percentages of antibiotic prescriptions substantially varied among different diagnosis categories and nearly three-quarters of antibiotic prescriptions had no clear indications and thus might be inappropriate. In total, 130,308 individual antibiotics were prescribed; among these, 60.4% (95% CI, 60.0–60.8%) belonged to FDA category B, 2.7% (95% CI, 2.1–3.5%) were classified as FDA category D and 16.8% (95% CI, 16.2–17.4%) were not assigned any FDA pregnancy category. Conclusions: Antibiotic prescriptions in ambulatory care during pregnancy were not highly prevalent in mainland China. However, a substantial proportion of antibiotics might have been prescribed without adequate indications. Antibiotics whose fetal safety has not been sufficiently illustrated were widely used in pregnant women.

US cost-effectiveness and budget impact of point-of-care NAAT for streptococcus.

In the United States, approximately 12 million individuals seek medical care for pharyngitis each year, accounting for about 2% of ambulatory care visits. Although the gold standard for diagnosing group A streptococcus (GAS) is culture, it is time intensive. Rapid antigen detection tests (RADT) with or without culture confirmation are commonly used instead. Although RADT provide results quickly, they generally have lower test sensitivity. Recently, point-of-care nucleic acid amplification tests (POC NAAT) have emerged. This study evaluates the cost-effectiveness and budget impact to the US payer of adopting POC NAAT. This study was a cost-effectiveness analysis, with costs and outcomes calculated via a decision tree. A decision-tree model quantified costs and outcomes associated with a GAS diagnostic strategy using POC NAAT compared with RADT + culture confirmation. Model inputs were derived from the published literature. Model outputs included costs and clinical effects: quality-adjusted life-days lost, GAS and antibiotic complications, number of patients appropriately treated, and antibiotic utilization. Sensitivity and scenario analyses were performed. Base-case analysis projected that a POC NAAT strategy would cost $44 per patient compared with $78 for RADT + culture. Compared with RADT + culture, POC NAAT would increase the number of appropriately treated patients and avert unnecessary use of antibiotics. The budget impact of POC NAAT was -0.4% relative to current budget over 5 years. Findings were robust in sensitivity analyses. Our results suggest that POC NAAT would be less costly and more effective than RADT + culture; POC NAAT adoption may yield cost savings to US third-party payers. Access to POC NAAT is important to optimize GAS diagnosis and treatment decisions in the United States.

Spending on Cardiovascular Disease and Cardiovascular Risk Factors in the United States: 1996 to 2016.

Spending on cardiovascular disease and cardiovascular risk factors (cardiovascular spending) accounts for a significant portion of overall US health care spending. Our objective was to describe US adult cardiovascular spending patterns in 2016, changes from 1996 to 2016, and factors associated with changes over time. We extracted information on adult cardiovascular spending from the Institute for Health Metrics and Evaluation's disease expenditure project, which combines data on insurance claims, emergency department and ambulatory care visits, inpatient and nursing care facility stays, and drug prescriptions to estimate >85% of all US health care spending. Cardiovascular spending (2016 US dollars) was stratified by age, sex, type of care, payer, and cardiovascular cause. Time trend and decomposition analyses quantified contributions of epidemiology, service price and intensity (spending per unit of utilization, eg, spending per inpatient bed-day), and population growth and aging to the increase in cardiovascular spending from 1996 to 2016. Adult cardiovascular spending increased from $212 billion in 1996 to $320 billion in 2016, a period when the US population increased by >52 million people, and median age increased from 33.2 to 36.9 years. Over this period, public insurance was responsible for the majority of cardiovascular spending (54%), followed by private insurance (37%) and out-of-pocket spending (9%). Health services for ischemic heart disease ($80 billion) and hypertension ($71 billion) led to the most spending in 2016. Increased spending between 1996 and 2016 was primarily driven by treatment of hypertension, hyperlipidemia, and atrial fibrillation/flutter, for which spending rose by $42 billion, $18 billion, and $16 billion, respectively. Increasing service price and intensity alone were associated with a 51%, or $88 billion, cardiovascular spending increase from 1996 to 2016, whereas changes in disease prevalence were associated with a 37%, or $36 billion, spending reduction over the same period, after taking into account population growth and population aging. US adult cardiovascular spending increased by >$100 billion from 1996 to 2016. Policies tailored to control service price and intensity and preferentially reimburse higher quality care could help counteract future spending increases caused by population aging and growth.

Characterizing the Epidemiology and Provider Landscape of Male Infertility Care in the United States

ObjectiveTo characterize the epidemiology of male factor infertility and identify which types of providers are treating infertile men in the United States. Materials and methodsThe National Ambulatory Medical Care Survey was queried between 2006 and 2016 for all ambulatory care visits. Men with a diagnosis of infertility were identified by international classification of disease coding. Comorbidities, demographic and visit information were abstracted from the patients’ medical record by a combination of trained surveyors and physicians. The survey data was weighted to create nationally representative estimates, and a combination of Chi-squared and Student's t-tests were utilized to determine significance. Result(s)Among the 8.7 billion patient visits between 2006 and 2016, there were 3,422,000 male encounters with a diagnosis of male factor infertility. The most common provider type for male factor infertility encounters was urology (42.12%) followed by primary care (39.79%), gynecology (7.05%) and all other provider types (11.01%). A significant number of men seen for infertility had comorbidities such as cancer (115,000 men, 3.36%) diabetes (267,000 men, 7.81%), depression (301,000 men, 8.8%), and active tobacco use (857,000 men, 30.3%). ConclusionIn a nationally representative sample, more than 50% of ambulatory care visits for male factor infertility were not seen by urologists. These men also had a significant number of comorbidities for a relatively young cohort, emphasizing the importance of multidisciplinary care for men with a diagnosis of infertility.

Emergency Department and Ambulatory Care Visits in the First Twelve Months of Coverage Under Medicaid Expansion: A Group-Based Trajectory Analysis

More than 17 million people have gained health insurance coverage through the Patient Protection and Affordable Care Act's Medicaid expansion. Few studies have examined heterogeneity within the Medicaid expansion population. We do so based on time-varying patterns of emergency department (ED) and ambulatory care use, and characterize diagnoses associated with ED and ambulatory care visits to evaluate whether certain diagnoses predominate in individual trajectories. We used group-based multitrajectory modeling to jointly estimate trajectories of ambulatory care and ED utilization in the first 12 months of enrollment among Pennsylvania Medicaid expansion enrollees from 2015 to2017. Among 601,877 expansion enrollees, we identified 6 distinct groups based on joint trajectories of ED and ambulatory care use. Mean ED use varied across groups from 3.4 to 48.7 visits per 100 enrollees in the first month and between 2.8 and 44.0 visits per 100 enrollees in month 12. Mean ambulatory visit rates varied from 0.0 to 179 visits per 100 enrollees in the first month and from 0.0 to 274 visits in month 12. Rates of ED visits did not change over time, but rates of ambulatory care visits increased by at least 50% among 4 groups during the study period. Groups varied on chronic condition diagnoses, including mental health and substance use disorders, as well as diagnoses associated with ambulatory care visits. We found substantial variation in rates of ED and ambulatory care use across empirically defined subgroups of Medicaid expansion enrollees. We also identified heterogeneity among the diagnoses associated with these visits. This data-driven approach may be used to target resources to encourage efficient use of ED services and support engagement with ambulatory care clinicians.

Resource Use Among Diabetes Patients Who Mainly Visit Primary Care Physicians Versus Medical Specialists: a Retrospective Cohort Study.

It is not uncommon for medical specialists to predominantly care for patients with certain chronic conditions rather than primary care physicians (PCPs), yet the resource implications from such patterns of care are not well understood. To assess resource use of diabetes patients who predominantly visit a PCP versus a medical specialist. Retrospective cohort study of diabetes patients aging into the traditional Medicare program. Patients were attributed to a PCP or medical specialist annually based on a preponderance of ambulatory care visits and categorized according to whether attribution changed year to year. Propensity score weighting was used to balance baseline demographic characteristics, diabetes complications, and underlying health conditions between patients attributed to PCPs and to medical specialists. Spending and utilization were measured up to 3 patient-years. A total of 141,558 patient-years. Total visits, unique physicians, hospital admissions, emergency department visits, procedures, imaging, and tests. Each year, roughly 70% of patients maintained attribution to a PCP and 15% to a medical specialist relative to the previous year. After propensity weighting, patients continuously attributed to a PCP versus medical specialist from 1 year to the next had lower average total payer payments ($10,326 [SD $57,386] versus $14,971 [SD $74,112], P<0.0001) and lower total patient out-of-pocket payments ($1,707 [SD $6,020] versus $2,443 [SD $7,984], P<0.0001). Rates of hospitalization, emergency department visits, procedures, imaging, and tests were lower among patients attributed to PCPs as well. Older adults with diabetes who receive more of their ambulatory care from a PCP instead of a medical specialist show evidence of lower resource use.

33. Telemedicine in Pediatric and Adolescent Gynecology

<h3>Background</h3> Telemedicine is broadly used to define medical care delivered remotely through telecommunication technology. This practice is recognized as an alternative strategy to traditional healthcare delivery with comparable health outcomes, and it has been rapidly expanded further in the context of the COVID-19 pandemic. While our clinicians have found telemedicine to be a helpful and innovative approach to medicine, its use specific to pediatric and adolescent gynecology has not been published. The primary outcome of this study was to determine the feasibility of virtual visits for ambulatory care in pediatric and adolescent gynecology. <h3>Methods</h3> This was a retrospective study on the use of telemedicine by the gynecology division at a tertiary pediatric hospital from January 1, 2020, to June 1, 2020. Video-based virtual visits through a hospital-supported software were conducted during the eligible time period. Patient demographics, visit diagnoses, and operational characteristics of the completed visits were obtained. The study received IRB approval. <h3>Results</h3> There were a total of 654 virtual visits for 614 patients. Ninety-one percent of patients were in-state (558/654), and the median age of patients seen was 17 years (range 0 – 37 years). Five hundred and two out of 654 visits were return visits (76.8%), 115/654 were new patient visits (17.6%), and 32/654 (4.89%) were post-operative follow-up. The median duration of a virtual visit was 12 minutes and 39 seconds (range 5 minutes to over 1 hour). The most common gynecologic diagnoses were dysmenorrhea/endometriosis (N=485), abnormal uterine bleeding (N=225), and pelvic pain (N=82). Visits were further assessed to determine if a follow-up in-person visit was needed within 90 days after the virtual visit. From the 654 virtual visits, 14 follow-up visits were in-person; 5 were within 30 days from initial virtual visit, 6 were within 60 days, and 3 were within 90 days. The most common complaints that prompted an in-person follow-up were contraception administration (depot medroxyprogesterone, intrauterine device) (N=4), vulvovaginal symptoms (N=4), congenital anomaly exam (N=1), abnormal uterine bleeding exam (N=1), and an ovarian cyst (N=1). <h3>Conclusions</h3> Telemedicine is a feasible method for healthcare delivery in pediatric and adolescent gynecology with low rates of short interval in-person follow-up required. Virtual visits can be conducted for a range of patients with a variety of gynecologic conditions, upon initial presentation and follow-up.

Four-Month Clinical Status of a Cohort of Patients After Hospitalization for COVID-19

Little is known about long-term sequelae of COVID-19. To describe the consequences at 4 months in patients hospitalized for COVID-19. In a prospective uncontrolled cohort study, survivors of COVID-19 who had been hospitalized in a university hospital in France between March 1 and May 29, 2020, underwent a telephone assessment 4 months after discharge, between July 15 and September 18, 2020. Patients with relevant symptoms and all patients hospitalized in an intensive care unit (ICU) were invited for further assessment at an ambulatory care visit. Survival of hospitalization for COVID-19. Respiratory, cognitive, and functional symptoms were assessed by telephone with the Q3PC cognitive screening questionnaire and a checklist of symptoms. At the ambulatory care visit, patients underwent pulmonary function tests, lung computed tomographic scan, psychometric and cognitive tests (including the 36-Item Short-Form Health Survey and 20-item Multidimensional Fatigue Inventory), and, for patients who had been hospitalized in the ICU or reported ongoing symptoms, echocardiography. Among 834 eligible patients, 478 were evaluated by telephone (mean age, 61 years [SD, 16 years]; 201 men, 277 women). During the telephone interview, 244 patients (51%) declared at least 1 symptom that did not exist before COVID-19: fatigue in 31%, cognitive symptoms in 21%, and new-onset dyspnea in 16%. There was further evaluation in 177 patients (37%), including 97 of 142 former ICU patients. The median 20-item Multidimensional Fatigue Inventory score (n = 130) was 4.5 (interquartile range, 3.0-5.0) for reduced motivation and 3.7 (interquartile range, 3.0-4.5) for mental fatigue (possible range, 1 [best] to 5 [worst]). The median 36-Item Short-Form Health Survey score (n = 145) was 25 (interquartile range, 25.0-75.0) for the subscale "role limited owing to physical problems" (possible range, 0 [best] to 100 [worst]). Computed tomographic lung-scan abnormalities were found in 108 of 171 patients (63%), mainly subtle ground-glass opacities. Fibrotic lesions were observed in 33 of 171 patients (19%), involving less than 25% of parenchyma in all but 1 patient. Fibrotic lesions were observed in 19 of 49 survivors (39%) with acute respiratory distress syndrome. Among 94 former ICU patients, anxiety, depression, and posttraumatic symptoms were observed in 23%, 18%, and 7%, respectively. The left ventricular ejection fraction was less than 50% in 8 of 83 ICU patients (10%). New-onset chronic kidney disease was observed in 2 ICU patients. Serology was positive in 172 of 177 outpatients (97%). Four months after hospitalization for COVID-19, a cohort of patients frequently reported symptoms not previously present, and lung-scan abnormalities were common among those who were tested. These findings are limited by the absence of a control group and of pre-COVID assessments in this cohort. Further research is needed to understand longer-term outcomes and whether these findings reflect associations with the disease.

Does Housing Improve Health Care Utilization and Costs? A Longitudinal Analysis of Health Administrative Data Linked to a Cohort of Individuals With a History of Homelessness.

Individuals who are homeless have complex health care needs, which contribute to the frequent use of health services. In this study, we investigated the relationship between housing and health care utilization among adults with a history of homelessness in Ontario. Survey data from a 4-year prospective cohort study were linked with administrative health records in Ontario. Annual rates of health encounters and mean costs were compared across housing categories (homeless, inconsistently housed, housed), which were based on the percentage of time an individual was housed. Generalized estimating equations were applied to estimate the average annual effect of housing status on health care utilization and costs. Over the study period, the proportion of individuals who were housed increased from 37% to 69%. The unadjusted rates of ambulatory care visits, prescription medications, and laboratory tests were highest during person-years spent housed or inconsistently housed and the rate of emergency department visits was lowest during person-years spent housed. Following adjustment, the rate of prescription claims remained higher during person-years spent housed or inconsistently housed compared with the homeless. Rate ratios for other health care encounters were not significant (P>0.05). An interaction between time and housing status was observed for total health care costs; as the percentage of days housed increased, the average costs increased in year 1 and decreased in years 2-4. These findings highlight the effects of housing on health care encounters and costs over a 4-year study period. The rate of prescription medications was higher during person-years spent housed or inconsistently housed compared with the homeless. The cost analysis suggests that housing may reduce health care costs over time; however, future work is needed to confirm the reason for the reduction in total costs observed in later years.

Does socio-economic status influence the effect of multimorbidity on the frequent use of ambulatory care services in a universal healthcare system? A population-based cohort study

BackgroundFrequent healthcare users place a significant burden on health systems. Factors such as multimorbidity and low socioeconomic status have been associated with high use of ambulatory care services (emergency rooms, general practitioners and specialist physicians). However, the combined effect of these two factors remains poorly understood. Our goal was to determine whether the risk of being a frequent user of ambulatory care is influenced by an interaction between multimorbidity and socioeconomic status, in an entire population covered by a universal health system.MethodsUsing a linkage of administrative databases, we conducted a population-based cohort study of all adults in Quebec, Canada. Multimorbidity (defined as the number of different diseases) was assessed over a two-year period from April 1st 2012 to March 31st 2014 and socioeconomic status was estimated using a validated material deprivation index. Frequents users for a particular category of ambulatory services had a number of visits among the highest 5% in the total population during the 2014–15 fiscal year. We used ajusted logistic regressions to model the association between frequent use of health services and multimorbidity, depending on socioeconomic status.ResultsFrequent users (5.1% of the population) were responsible for 25.2% of all ambulatory care visits. The lower the socioeconomic status, the higher the burden of chronic diseases, and the more frequent the visits to emergency departments and general practitioners. Socioeconomic status modified the association between multimorbidity and frequent visits to specialist physicians: those with low socioeconomic status visited specialist physicians less often. The difference in adjusted proportions of frequent use between the most deprived and the least deprived individuals varied from 0.1% for those without any chronic disease to 5.1% for those with four or more chronic diseases. No such differences in proportions were observed for frequent visits to an emergency room or frequent visits to a general practitioner.ConclusionEven in a universal healthcare system, the gap between socioeconomic groups widens as a function of multimorbidity with regard to visits to the specialist physicians. Further studies are needed to better understand the differential use of specialized care by the most deprived individuals.

Addressing Antibiotic Overuse in the Outpatient Setting: Lessons From Behavioral Economics

Addressing Antibiotic Overuse in the Outpatient Setting: Lessons From Behavioral Economics

Incidence of Medically Attended Acute Respiratory Illnesses Due to Respiratory Viruses Across the Life Course During the 2018/19 Influenza Season.

BackgroundWhile multiple respiratory viruses circulate in humans, few studies have compared the incidence of different viruses across the life course. We estimated the incidence of outpatient illness due to 12 different viruses during November 2018 through April 2019 in a fully enumerated population.MethodsWe conducted active surveillance for ambulatory care visits for acute respiratory illness (ARI) among members of Kaiser Permanente Washington (KPWA). Enrolled patients provided respiratory swab specimens which were tested for 12 respiratory viruses using RT-PCR. We estimated the cumulative incidence of infection due to each virus overall and by age group.ResultsThe KPWA population under surveillance included 202,562 individuals, of whom 2,767 (1.4%) were enrolled in the study. Influenza A(H3N2) was the most commonly detected virus, with an overall incidence 21 medically attended illnesses per 1,000 population; the next most common viruses were influenza A(H1N1) (18 per 1,000), coronaviruses (13 per 1,000), respiratory syncytial virus (RSV, 13 per 1,000), and rhinovirus (9 per 1,000). RSV was the most common cause of medically attended ARI among children aged 1-4 years; coronaviruses were the most common among adults aged ≥65 years.ConclusionsConsistent with other studies focused on single viruses, we found that influenza and RSV were major causes of acute respiratory illness in persons of all ages. In comparison, coronaviruses and rhinovirus were also important pathogens. Prior to the emergence of SARS-CoV-2, coronaviruses were the second-most common cause of medically attended ARI during the 2018/19 influenza season.

Short-term outcomes of endometriosis surgery in Ontario: A population-based cohort study.

Our objective was to compare the short-term outcomes by type of surgical management of endometriosis in Ontario, Canada and to characterize the population of women undergoing surgical management of endometriosis. We conducted a population-based cohort study including women aged 18-50years undergoing same-day or inpatient surgery for endometriosis from 1 April 2002 through 31 March 2018. Surgery was classified as minimally invasive hysterectomy (MIH), total abdominal hysterectomy (TAH) or minor or major conservative (uterus-preserving) surgery. Outcomes examined included length of stay, intraoperative complications, postoperative complications, emergency department visits, ambulatory care visits, and readmission. We estimated the relative risk of these outcomes in minor, major conservative surgery and TAH vs MIH adjusted for age, income quintile, parity, and comorbidities. A total of 85605 patients underwent surgery, 12.9% MIH, 22.1% TAH, 36.3% major conservative, and 28.6% minor conservative. The mean age at index surgery was 37.6±7.7years. Before surgery, 70.6% of patients had visited a physician for pain at least once (64.7% MIH, 69.5% TAH, 71.1% major conservative and 73.4% minor conservative) and 23.5% of patients had sought infertility consultation (5.7% MIH, 6.6% TAH, 29.3% major conservative and 37.1% minor conservative). The overall risk of intraoperative and postoperative complications was 1.5% and 4.7%, respectively. In adjusted models, compared with those undergoing minor conservative surgery, those having major conservative surgery were 1.77 (95% CI 1.49-2.11) times as likely to experience an intraoperative complication, those having MIH and TAH were 2.55 (95% CI 2.08-3.13) and 2.34 (95% CI 1.93-2.82) times as likely to do so, respectively. Similarly, compared with those undergoing minor conservative surgery, those having major conservative surgery were 2.60 (95% CI 2.30, 2.93) times as likely to experience any postoperative complication, and those having MIH and TAH were 4.69 (95% CI 4.11-5.36) and 5.38 (95% CI 4.76-6.09) times as likely to do so, respectively. Approximately one-third of patients undergoing surgical management for endometriosis in Ontario between 2002 and 2018 had a hysterectomy. Overall, complications following surgery were low, and dependent on extent of surgery. These results should help to inform preoperative counseling for patients and health policy development for providers.

Virtual care use before and during the COVID-19 pandemic: a repeated cross-sectional study.

Background:The coronavirus disease 2019 (COVID-19) pandemic is thought to have increased use of virtual care, but population-based studies are lacking. We aimed to assess the uptake of virtual care during the COVID-19 pandemic using comprehensive population-based data from Ontario.Methods:This was a repeated cross-sectional study design. We used administrative data to evaluate changes in in-person and virtual visits among all residents of Ontario before (2012–2019) and during (January–August 2020) the COVID-19 pandemic. We included all patients who had an ambulatory care visit in Ontario. We excluded claims for patients who were not Ontario residents or had an invalid or missing health card number. We compared monthly or quarterly virtual care use across age groups, neighbourhood income quintiles and chronic disease subgroups. We also examined physician characteristics that may have been associated with virtual care use.Results:Among all residents of Ontario (population 14.6 million), virtual care increased from 1.6% of total ambulatory visits in the second quarter of 2019 to 70.6% in the second quarter of 2020. The proportion of physicians who provided 1 or more virtual visits per year increased from 7.0% in the second quarter of 2019 to 85.9% in the second quarter of 2020. The proportion of Ontarians who had a virtual visit increased from 1.3% in 2019 to 29.2% in 2020. Older patients were the highest users of virtual care. The proportion of total virtual visits that were provided to patients residing in rural areas (v. urban areas) declined significantly between 2012 and 2020, reflecting a shift in virtual care to a service increasingly used in urban centres. The rates of virtual care use increased similarly across all conditions and across all income quintiles.Interpretation:Our findings show that Ontario’s approach to virtual care led to broad adoption across all provider groups, patient age, types of chronic diseases and neighborhood income. These findings have policy implications, including use of virtual care billing codes, for the ongoing use of virtual care during the second wave of the pandemic and beyond.

Impact of Psychiatric Comorbidity on Health Care Use in Rheumatoid Arthritis: A Population‐Based Study

ObjectivePsychiatric comorbidity is frequent in rheumatoid arthritis (RA) and complicates treatment. The present study was undertaken to describe the impact of psychiatric comorbidity on health care use (utilization) in RA.MethodsWe accessed administrative health data (1984–2016) and identified a prevalent cohort with diagnosed RA. Cases of RA (n = 12,984) were matched for age, sex, and region of residence with 5 controls (CNT) per case (n = 64,510). Within each cohort, we identified psychiatric morbidities (depression, anxiety, bipolar disorder, and schizophrenia [PSYC]), with active PSYC defined as ≥2 visits per year. For the years 2006–2016, annual rates of ambulatory care visits (mean ± SD per person) categorized by provider (family physician [FP], rheumatologist, psychiatrist, other specialist), hospitalization (% of cohort), days of hospitalization (mean ± SD), and dispensed drug types (mean ± SD per person) were compared among 4 groups (CNT, CNT plus PSYC, RA, and RA plus PSYC) using generalized linear models adjusted for age, sex, rural versus urban residence, income quintile, and total comorbidities. Estimated rates are reported with 95% confidence intervals (95% CIs). We tested within‐person and RA‐PSYC interaction effects.ResultsSubjects with RA were mainly female (72%) and urban residents (59%), with a mean ± SD age of 54 ± 16 years. Compared to RA without PSYC, RA with PSYC had more than additive (synergistic) visits (standardized mean difference [SMD] 10.92 [95% CI 10.25, 11.58]), hospitalizations (SMD 13% [95% CI 0.11, 0.14]), and hospital days (SMD 3.63 [95% CI 3.06, 4.19]) and were dispensed 6.85 more medication types (95% CI 6.43, 7.27). Cases of RA plus PSYC had increased visits to FPs (an additional SMD 8.92 [95% CI 8.35, 9.46] visits). PSYC increased utilization in within‐person models.ConclusionManaging psychiatric comorbidity effectively may reduce utilization in RA.

Growth of Ambulatory Virtual Visits and Differential Use by Patient Sociodemographics at One Urban Academic Medical Center During the COVID-19 Pandemic: Retrospective Analysis.

BackgroundDespite widespread interest in the use of virtual (ie, telephone and video) visits for ambulatory patient care during the COVID-19 pandemic, studies examining their adoption during the pandemic by race, sex, age, or insurance are lacking. Moreover, there have been limited evaluations to date of the impact of these sociodemographic factors on the use of telephone versus video visits. Such assessments are crucial to identify, understand, and address differences in care delivery across patient populations, particularly those that could affect access to or quality of care.ObjectiveThe aim of this study was to examine changes in ambulatory visit volume and type (ie, in-person vs virtual and telephone vs video visits) by patient sociodemographics during the COVID-19 pandemic at one urban academic medical center.MethodsWe compared volumes and patient sociodemographics (age, sex, race, insurance) for visits during the first 11 weeks following the COVID-19 national emergency declaration (March 15 to May 31, 2020) to visits in the corresponding weeks in 2019. Additionally, for visits during the COVID-19 study period, we examined differences in visit type (ie, in-person versus virtual, and telephone versus video visits) by sociodemographics using multivariate logistic regression.ResultsTotal visit volumes in the COVID-19 study period comprised 51.4% of the corresponding weeks in 2019 (n=80,081 vs n=155,884 visits). Although patient sociodemographics between the COVID-19 study period in 2020 and the corresponding weeks in 2019 were similar, 60.5% (n=48,475) of the visits were virtual, compared to 0% in 2019. Of the virtual visits, 61.2% (n=29,661) were video based, and 38.8% (n=18,814) were telephone based. In the COVID-19 study period, virtual (vs in-person) visits were more likely among patients with race categorized as other (vs White) and patients with Medicare (vs commercial) insurance and less likely for men, patients aged 0-17 years, 65-74 years, or ≥75 years (compared to patients aged 18-45 years), and patients with Medicaid insurance or insurance categorized as other. Among virtual visits, compared to telephone visits, video visits were more likely to be adopted by patients aged 0-17 years (vs 18-45 years), but less likely for all other age groups, men, Black (vs White) patients, and patients with Medicare or Medicaid (vs commercial) insurance.ConclusionsVirtual visits comprised the majority of ambulatory visits during the COVID-19 study period, of which a majority were by video. Sociodemographic differences existed in the use of virtual versus in-person and video versus telephone visits. To ensure equitable care delivery, we present five policy recommendations to inform the further development of virtual visit programs and their reimbursement.

How Can One Strengthen a Tiered Healthcare System through Health System Reform? Lessons Learnt from Beijing, China.

How one can reshape the current healthcare sector into a tiered healthcare system with clarified division of functions between primary care facilities and hospitals, and improve the utilization of primary care, is a worldwide problem, especially for the low and middle-income countries (LMICs). This paper aimed to evaluate the impact of the Beijing Reform on healthcare-seeking behavior and tried to explain the mechanism of the change of patient flow. In this before and after study, we evaluated the changes of outpatient visits and inpatient visits among different levels of health facilities. Using the monitored and statistical data of 373 healthcare institutions 1-year before and 1-year after the Beijing Reform, interrupted time series analysis was applied to evaluate the impact of the reform on healthcare-seeking behavior. Semi-structured interviews were used to further explore the mechanisms of the changes. One year after the reform, the flow of outpatients changed from tertiary hospitals to community health centers with an 11.90% decrease of outpatients in tertiary hospitals compared to a 15.01% increase in primary healthcare facilities. The number of ambulatory care visits in primary healthcare (PHC) showed a significant upward trend (P < 0.10), and the reform had a significant impact on the average number of ambulatory care visits per institution in Beijing’s tertiary hospitals (p < 0.10). We concluded that the Beijing Reform has attracted a substantial number of ambulatory care visits from hospitals to primary healthcare facilities in the short-term. Comprehensive reform policies were necessary to align incentives among relative stakeholders, which was a critical lesson for other provinces in China and other LMICs.
