Association between food insecurity and healthcare utilization among patients at a breast oncology center.

143 Background: A breast cancer (BC) diagnosis often creates or exacerbates financial stress. As a result, many patients with BC struggle with a lack of consistent access to nutritious food due to limited resources, a condition termed “food insecurity” (FI). We investigated the association between FI and healthcare utilization among breast oncology patients at our urban academic medical center. Methods: Screening for health-related social needs (HRSN) was conducted primarily through the electronic patient portal, at appointment registration for a breast oncology clinic visit. The 8-item HRSN survey included 2 questions on access to food resources and 1 question quantifying emergency department (ED) visits over the past year. Any level of food hardship or concern constituted a positive FI screen. We conducted a retrospective analysis among patients evaluated between 11/2/22 and 4/20/24. Clinical and demographic data were obtained from the electronic health record (EHR). We evaluated the association between FI and health care utilization measures (ED visits, inpatient admissions) with a Pearson's Chi-squared test and univariate logistic regression. Results: A total of 2820 patients were screened for HRSN and provided responses to at least 1 FI question, of which 19.7% (555) reported some level of FI. Food-insecure patients self-reported significantly higher rates of ED visits in the past 12 months compared to food-secure patients: 43.2% vs 22.6% reported at least 1 ED visit, respectively (p<0.001), and 25.0% vs 8.45% reported multiple ED visits, respectively (p<0.001). Overall, FI was associated with 2.5 times the odds of self-reporting at least 1 ED visit (univariate OR 2.47, p<0.001). Similarly, on review of EHR data, 33.3% of food-insecure patients had at least 1 ED visit (vs 20.0% of food-secure patients, p<0.001), and 6.13% had 3 or more ED visits (vs 2.83%, p<0.001) during the study period. On univariate analysis, food-insecure patients had double the odds of having at least 1 ED visit documented in the EHR (univariate OR 2.00, p<0.001). We examined reasons for ED presentations among 186 food-insecure patients with ED visits during the study period, and found that 23.8% had at least 1 cancer-related complaint (oncological treatment-related (16.8%) and/or BC symptom-related (8.6%)). The incidence of inpatient admissions during the study period was similar among food-insecure vs food-secure patients (19.8% vs 18.4%, p=0.467). Conclusions: In this analysis of FI and health care delivery measures, ED utilization was significantly higher among food-insecure patients. A quarter of food-insecure patients who presented to the ED had oncological complaints. FI may be a marker of unmet healthcare needs in patient with cancer, and targeted interventions focused on symptom monitoring and management are warranted to optimize healthcare utilization.

Impact of continuous glucose monitoring on emergency department visits and all-cause hospitalization rates among Medicaid beneficiaries with type 2 diabetes treated with multiple daily insulin or basal insulin therapy.

The increasing prevalence of diabetes in the United States continues to drive a steady rise in health care resource utilization, especially emergency department visits and all-cause hospitalizations, and the associated costs. To investigate the impact of continuous glucose monitoring (CGM) on emergency department visits and all-cause hospitalizations among Medicaid beneficiaries with type 2 diabetes (T2D) treated with multiple daily insulin injections (MDIs) or basal insulin therapy (BIT) in a real-world setting. In this retrospective, 12-month analysis, we used the Inovalon Insights claims dataset to evaluate the effects of CGM acquisition on emergency department visits and all-cause hospitalizations in the Managed Medicaid population. The analysis included 44,941 beneficiaries with T2D who were treated with MDIs (n = 35,367) or BIT (n = 9,574). Primary outcomes were changes in the number of emergency department visits and all-cause hospitalizations following 6 months after acquisition of CGM (post-index period) compared with 6 month prior to CGM acquisition (pre-index period). The first claim for CGM was the index date. Inclusion criteria were as follows: aged younger than 65 years, diagnosis of T2D, claims for short- or rapid-acting insulin (MDI group) or basal insulin (not rapid-acting) (BIT group), acquisition of a CGM device between January 1, 2017, and September 30, 2022, and continuous enrollment in their health plan throughout the pre-index and post-index periods. In the MDI group, all-cause inpatient hospitalization rates decreased from 3.25 to 2.29 events/patient-year (hazard ratio = 0.12; 95% CI = 0.11-0.13; P < 0.001) and emergency department visit rates decreased from 2.15 to 1.86 events/patient-year (hazard ratio = 0.52; 95% CI = 0.50-0.53; P < 0.001). In the BIT group, all-cause inpatient hospitalization rates decreased from 1.63 to 1.39 events/patient-year (hazard ratio = 0.11; 95% CI = 0.09-0.12; P < 0.001) and emergency department visit rates decreased from 1.60 to 1.43 events/patient-year (hazard ratio = 0.47; 95% CI = 0.44-0.50; P < 0.001). Acquisition of CGM is associated with significant reductions in emergency department visits and all-cause hospitalizations among people with T2D treated with MDIs or BIT.

Health service utilization, substance use treatment response, and death in patients with opioid use disorder and comorbid hepatitis C findings from prospective cohort study with administrative database linkage

BackgroundAmong patients with opioid use disorder (OUD), high rates of overdose and death have been reported in subgroups with Hepatitis C Virus (HCV). Evidence on the comorbid effect of HCV on clinical and substance use trajectories has been limited by small sample sizes, short follow-up, and heavy reliance on administrative data which lacks granularity on important prognostic factors. Additionally, few studies include populations on substance use treatment. AimTo establish the impact of HCV exposure (antibody positivity) on health care utilization patterns, substance use treatment response, and death in a cohort of patients with OUD on opioid agonist therapy (OAT). MethodsThis multi-center prospective cohort study recruited adult patients with OUD on OAT from 57 substance use treatment centers in Ontario, Canada. The study collected substance use outcomes, and classified patients with ≥50 % positive opioid urine screens over one year of follow-up as having poor treatment response. Additional data obtained via linkage with ICES administrative databases evaluated the relationship between HCV status, healthcare service utilization, and death over 3 years of follow-up. Multiple logistic regression models established the adjusted impact of HCV on various outcomes. ResultsAmong recruited participants (n = 3430), 44.10 % were female with a mean age of 38.64 years (Standard deviation: 10.96). HCV was prevalent in 10.6 % of the cohort (n = 365). Methadone was used most often (83.9 %, n = 2876), followed by sublingual buprenorphine (16.2 %, n = 554). Over the three-year follow-up, 5.3 % of patients died (n = 181). Unadjusted results reveal rates of hospitalization (all-cause, mental-health related, critical care) and emergency department visits (mental health-related), were significantly higher among HCV patients. Associations diminished in adjusted models. Active injection drug use exhibited the highest predictive risk for all outcomes. ConclusionA high degree of acute physical and mental illness and its resulting health service utilization burden is concentrated among patients with OUD and comorbid HCV. Future research should explore the role for targeted interventions and how best to implement integrated healthcare models to better address the complex health needs of HCV populations who inject drugs.

Association of health status and hospitalization risk for peripheral artery disease in the PORTRAIT registry.

Healthcare utilization for patients with peripheral artery disease (PAD) is high, but stratifying patients' risk of hospitalization at initial evaluation is challenging. We examined the association between health status at PAD presentation and risk of (1) combined all-cause hospital admissions and emergency department (ED) visits and (2) all-cause hospital admissions. Patients with claudication enrolled at US sites in the PORTRAIT registry were included. Health status was assessed using the Peripheral Artery Questionnaire (PAQ), a PAD-specific patient-reported outcome measure. Crude overall and cause-specific hospital admissions and ED visits were reported by PAQ overall summary score (PAQ-OS) ranges (0-24, 25-49, 50-74, and 75-100). Kaplan-Meier survival and unadjusted and adjusted Cox proportional hazards models examined the association between baseline PAQ scores and (1) combined all-cause hospital admissions or ED visits and (2) all-cause hospital admissions over 12 months. Of 796 patients, 349 (44%) had a hospital admission or ED visit over 12 months. Patients in the lowest (PAQ-OS = 0-24) versus the highest range (PAQ-OS = 75-100) had higher rates of 12-month (53.3% vs 22.4%) hospital admission and ED visits. In the adjusted model, each 10-point decrease in PAQ-OS was associated with a higher risk of all-cause hospital admission and ED visits (HR = 1.1, 95% CI 1.1-1.2, p < 0.0010) and all-cause hospital admission (HR = 1.1, 95% CI 1.1-1.2, p < 0.0010) at 12 months. PAD-specific health status is associated with an increased risk of healthcare utilization. Baseline health status may help stratify risk in patients with PAD, although replication and further validation of results are necessary.

Burden of Diabetes Mellitus in the Medically Underserved Rio Grande Valley.

Introduction Diabetes mellitus (DM) encompasses metabolic disorders characterized by elevated blood sugar. This study aimed to evaluate the prevalence and associated metrics of DM in the Rio Grande Valley (RGV), a low-income and medically underserved region in the United States, and compare these metrics to the national averages from 2012 to 2022. Methods A retrospective cross-sectional analysis was conducted using publicly accessible data from the Centers for Medicare and Medicaid Services (CMS). Metrics analyzed included DM prevalence, average principal cost, rates of emergency department visits, hospitalizations, screenings, and prevalence of obesity. Data from the RGV counties were compared to national averages using Mann-Whitney U tests, with a p-value of <0.05 considered significant. Results From 2012 to 2022, DM affected patients in the RGV (43.95%) at significantly higher rates than the national average (26.73%) (p < 0.001). Obesity prevalence in the RGV was at higher rates than the national average (24.41% vs. 15.55%, p < 0.01). The screening rates of DM exceeded the national average (10.64% vs. 5.09%, p < 0.001). The average principal cost for patients in the RGV ($1,920.45) to treat DM was significantly greater than the national average principal cost ($859.64) (p < 0.001). The RGV also reported higher rates of ED visits (16.82 vs. 8.82 per 1,000 beneficiaries, p < 0.001) and hospitalizations (7.75 vs. 3.82 per 1,000 beneficiaries, p < 0.001). Conclusion The RGV exhibits significantly higher rates of DM and DM-associated metrics compared to the national averages, highlighting substantial public health disparities.

Timely data on the dynamic drug supply is crucial in addressing the ongoing drug poisoning crisis. The team is exploring ways to share information with emergency responders, healthcare providers, government officials, and pwSUD.

ObjectiveTransitioning from hospitals to primary care brings significant challenges, including increased readmission rates, mortality, and costs due to information gaps. Alberta, Canada, addressed this by integrating 1000+ health systems and implementing Connect Care (CC), a Clinical Information System (CIS), to enhance patient safety and care coordination. In 2020, the Primary Health Care Integration Network (PHCIN) released the Home to Hospital to Home (H2H2H) Transitions Guideline and metrics to improve patient outcomes and system integration. ApproachThis study examines provincial data on H2H2H transitions measures from acute care hospitals using CC between April 1, 2022, and October 31, 2023, to assess transitions and support improvement efforts. CC data assesses transition components, including confirming primary care providers at hospital discharge, utilizing the LACE Readmission Risk Index, and ensuring timely discharge summary (DS) signoffs. It links with administrative data to evaluate post-discharge outcomes like primary care physician follow-up, unplanned readmissions, and Emergency Department (ED) visits. Results47 CC-implemented sites show nearly 80% discharges identified a primary care provider; less than 5% incorporated the LACE index in DS. About 90-93% of DS were signed within 24-72 hours. Approximately 62% of moderate-risk and 55% of high-risk discharges received timely follow-up. Readmission and ED visit rates within 7-30 days varied from 2-8% and 5-11% respectively. ConclusionIn conclusion, adopting CC and H2H2H transition metrics facilitates integrated care measurement, highlighting the need for risk index inclusion and high-risk discharge follow-up for improved patient transitions. Sustained initiatives are vital for optimal outcomes and system integration in Alberta.

The Impact of COVID-19 on Mental Health Outcomes among Recipients of Ontario Social Assistance Benefits

Objectives/ApproachWe linked the Ontario Social Assistance (OSA) Benefit Unit file from the Ministry of Children, Community and Social Services to provincial health administrative datasets housed at ICES to examine the impact of COVID-19 on Mental Health and Addictions (MHA) service use among OSA recipients. Those receiving OSA benefits for February 2020 were matched to Ontario residents not receiving benefits based on age (±1 year), sex, income, expected resource utilization, and area of residence (N=771,891 matched pairs). We computed rates of MHA-related emergency department (ED) visits and hospitalizations in the 16-month period before (November 2018-February 2020) and after (March 2020-June 2021) pandemic onset. ResultsMHA-related ED visit rates were much greater among OSA recipients (8.82 per 1,000 person-months) compared with matched controls (1.83 per 1,000 person-months) in the post-COVID period (Relative Rate [RR]=4.82; 95% Confidence Interval [95%CI] 4.75-4.89). Comparatively, MHA-related ED visit rates were also greater among OSA recipients (9.85 per 1,000 person-months) compared with controls (2.38 per 1,000 person-months) during the pre-COVID period (RR=4.13; 95%CI 4.08-4.18). The pre-COVID and post-COVID period RRs comparing OSA recipients and matched controls were significantly different (p&lt;0.001). Results were consistent when examining MHA-related hospitalizations. Conclusions/ImplicationsWhile MHA-related ED visits and hospitalizations rates were significantly higher in OSA recipients than matched controls in both time periods, this difference increased following the onset of COVID-19. Increased reliance on hospital-based MHA services post-COVID represents the greater ongoing need for, and/or reduced access to, MHA-related ambulatory care for OSA recipients during the pandemic.

Comparing health service use before and after transition to a supported housing model for clients who experience severe and persistent mental illness in southwestern Ontario, Canada

Objective and ApproachBeginning in 2018, a provincially-funded custodial housing model in Ontario, Canada transitioned to a supported housing model that allowed more autonomy for clients who experience severe and persistent mental illness (SPMI). The objective of this study was to compare health service use before and after transition to the new Community Homes for Opportunity (CHO) program in southwestern Ontario between 2017 and 2019. Information about clients who transitioned to the CHO program were obtained from the Ontario Ministry of Health and Long-Term Care and linked to health administrative data at ICES. Rates of emergency department (ED) visits, primary care visits, and specialist visits in the one year before and after implementation of the CHO program were compared using conditional Poisson models. ResultsOf the 368 clients, approximately 40% were female and the mean age was 57 years old. Compared to before the transition, clients had more primary care visits (rate ratio [RR] = 1.21; 95% CI: 1.07-1.37) and specialist visits (RR = 1.33; 95% CI: 1.11-1.60) within the year after transition to the CHO program. There was no significant change in the use of emergency department visits following the transition (RR = 1.20; 95% CI: 0.96-1.50). ConclusionsSupported housing may be associated with greater use of primary and specialist care for clients who experience SPMI. ImplicationsThe new supported housing model may encourage clients to use more personalized health care, according to their specific needs. Such personalized support is crucial for clients with complex health care needs.

New and Pre-existing Eating Disorders Among Adolescents and Young Adults During the COVID-19 Pandemic: A Population-Based Cohort Study

ObjectivesOur understanding of the contribution of new presentations versus pre-existing eating disorders during the COVID-19 pandemic is limited. This study aims to evaluate rates of emergency department (ED) visits and hospitalizations for eating disorders among adolescents and young adults (YA) new to care and those with pre-existing eating disorders during the pandemic. ApproachWe conducted a population-based cross-sectional study using linked health administrative data for Ontario residents aged 10-26 during the pre-pandemic (Jan. 1, 2017-Feb. 29, 2020) and pandemic periods (Mar. 1, 2020-Jun. 30, 2022). We used Poisson generalized estimating equations models to predict expected overall and monthly rates of eating disorder-related ED visits and hospitalizations among those with a new and pre-existing eating disorder. ResultsCompared with expected rates, ED visits increased during the pandemic among only adolescents with new eating disorders (adolescent RR 2.12, 95% CI [1.84,2.45]). Additionally, both adolescents and YA with pre-existing eating disorders experienced an increase in ED visits (RR 2.78, 95% CI [2.28, 3.38] and RR 1.52, 95% CI [1.25, 1.85], respectively). Similarly, hospitalizations for new presentations increased solely for adolescents (RR 1.48, 95% CI [1.34,1.64]), while hospitalizations for pre-existing eating disorders increased for both adolescents (RR 1.82, 95% CI [1.43,2.32]) and YA (RR 1.12, 95% CI [1.01,1.23]). ConclusionsThere was an increase in acute care visits for eating disorders during the pandemic, especially among adolescents and YA with pre-existing conditions. This differentiation is important in advancing our understanding of the pandemic's effects on adolescents and YA and the healthcare system receiving them.

Aortic Dissections in the Elderly: Older Age in Patients With Acute Aortic Syndromes Is Associated With Delayed Time to Surgery.

In the setting of acute aortic syndromes, timely access to definitive surgical repair is of paramount importance. Older patients, primarily septuagenarians and octogenarians, undergoing emergent ascending arch repair experience higher rates of mortality compared to younger patients. Despite this risk, studies show that surgical management is still superior to medical management for this patient population. The objective of this study is to determine if older age impacts the time from presentation to the start of surgery for patients with acute aortic syndromes undergoing surgical repair. This retrospective review included all patients with acute aortic syndromes who underwent emergent ascending aortic arch repair from January 2018 to May 2023 at a single academic institution. Our analysis compared outcomes for older patients (age 70 years and older) with younger patients (age less than 70 years). Primary outcomes included 30-day mortality, postoperative stay, time from emergency department presentation to the start of surgery, and time from diagnosis with computed tomography to the start of surgery. Secondary outcomes included postoperative complications. Outcomes were analyzed using chi-squared and Student's t-tests, with significance set at p<0.05. Of 107 patients included (male, N=57), 71 (66%) were under the age of 70 and 36 (34%) were 70 years of age or older. The younger cohort had more male and non-White patients, with no differences in rates of hypertension, dyslipidemia, and smoking history. With no difference in the rate of transfers from outside hospitals, we observed longer times from presentation to the start of surgery for older patients compared to younger patients (7 hours and 13 minutes vs. 6 hours 25 minutes; p=0.02) and also for time of diagnosis to the start of surgery (4 hours 22 minutes vs. 3 hours 54 minutes; p=0.006). Older patients had higher rates of intraoperative (0% vs. 17%, p<0.001) and 30-day (7% vs. 44%, p<0.001) mortality. There were no differences in length of stay or in rates of postoperative complications and surgery-related emergency department visits. Patients aged 70 and older experienced delays from the time of presentation to the start of surgery and from time of diagnosis to the start of surgery. Age should not delay an individual from receiving timely transfer to a tertiary center for a higher level of care to better assess the patient's operative candidacy and determine appropriate treatment.

Optimizing care pathways: A study of the urgent dispatch program and its impact on emergency department visits

IntroductionThe use of acute hospital-level care at home (hospital-at-home) for patients who are chronically ill has led to decreased medical costs, amount of sedentary time, and hospital admissions. Our large integrated healthcare system identified the need to develop a mechanism through which to decrease emergency department (ED) visits in this patient population by creating a home acute care program called Urgent Dispatch. The primary objective of this study was to determine the medical condition for referral and seven and 30-day ED visit rates. MethodsThis was a retrospective cohort of all patients referred to the Urgent Dispatch program from April 1, 2021, through February 28, 2022. We assessed encounters for patient demographics, referral source, reason for visit, number of at home visits, total number of days in the program, and determined if the patient had an ED encounter within seven and 30 days of participation in the program. The healthcare system includes 10 hospitals (academic, community and rural), 17 emergency departments (hospital-based and freestanding) and their associated outpatient clinics. ResultsA total of 2218 orders were placed with 1530 (70.8 %) resulting in enrollment in the Urgent Dispatch program. The majority were elderly (75 ± 15.6), white (70 %), female (64.4 %), and had Medicare as their primary insurance (82 %). The average number of visits made by Urgent Dispatch was 1.46 (SD ± 0.95). The average number of days enrolled in the program was 2.4 (SD ± 4.1). The top three referral sources to the program were outpatient primary care (42 %), home care (28 %) and emergency medicine (20 %). The top body systems requiring a visit were cardiovascular (22 %), general (18 %), and respiratory (17.2 %). Of the 1530 urgent dispatch referrals, 19.8 % (n = 303) had an ED visit within seven days, 12 % (n = 183) had an ED visit within eight to 30 days, and 68.2 % (n = 1044) had no ED visit. ConclusionA home-based care model of healthcare delivery for patients with chronic medical conditions can provide effective care, with 80.2 % of patients avoiding an ED visit within seven days and 68.2 % avoiding an ED visit within 30 days.

Risk factors and clinical outcomes associated with multiple as opposed to single pathogens detected on the gastrointestinal disease polymerase chain reaction assay

BackgroundThe use of gastrointestinal disease multiplex polymerase chain reaction (GI PCR) testing has become common for suspected gastrointestinal infection. Patients often test positive for multiple pathogens simultaneously through GI PCR, although the clinical significance of this is uncertain.MethodsThis retrospective cohort study investigated risk factors and clinical outcomes associated with detection of multiple (as opposed to single) pathogens on GI PCR. We included adult patients who underwent GI PCR testing from 2020 to 2023 and had one or more pathogens detected. We compared patients with multiple versus those with single pathogens and hypothesized that immunosuppression would be a risk factor for detection of multiple pathogens. We further hypothesized that, during the 90 days after GI PCR testing, patients with multiple pathogens would have worse clinical outcomes such as increased rates of emergency department (ED) visits, death, hospitalization, or ambulatory care visits.ResultsGI PCR was positive in 1341 (29%) of tested patients; 356 patients had multiple pathogens and 985 had one pathogen. The most common pathogens included Enteropathogenic Escherichia coli (EPEC, 27%), norovirus (17%), and Enteroaggregative E. coli (EAEC, 14%) in both multi- and singly positive patients. Immunosuppression was not associated with multiple pathogens (adjusted odds ratio [aOR] 1.35, 95% CI 0.96, 1.86). The factors most associated with multiple pathogens were Hispanic ethnicity (OR 1.86, 95% CI 1.42, 2.45) and chronic kidney disease (OR 1.69, 95% CI 1.13, 2.49). Patients with multiple pathogens were more likely to have ED visits during the 90 days after GI PCR testing (40% vs. 32%, p < 0.01), but they were not more likely to die, be hospitalized, or to have ambulatory medical visits.ConclusionsImmunosuppression was not associated with detection of multiple as opposed to single pathogens on GI PCR testing. There were worse clinical outcomes associated with detection of multiple pathogens, although these effects were modest.

Comparing Rates of Minimal Clinically Important Difference Between Manual and Robotic-Assisted Total Knee Arthroplasty

BackgroundDifferences in patient-reported outcome measures (PROMs) between manual total knee arthroplasty (mTKA) and robotic-assisted TKA (rTKA) have not been adequately assessed. We compared the minimal clinically important difference (MCID) for improvement (MCID-I) and worsening (MCID-W) between mTKA and rTKA patients. MethodsPatients who underwent primary TKA (874 mTKA and 439 rTKA) with complete preoperative and 1-year postoperative PROMs were retrospectively identified using a multihospital joint arthroplasty registry. Patient-Reported Outcomes Measurement Information System Physical Function Short Form 10a (PROMIS PF-10a), PROMIS Global – Physical, or Knee Injury and Osteoarthritis Outcome Score-Physical Function Short Form were collected. The MCID-I, MCID-W, and “no significant change” rates were calculated using distribution-based methods. Propensity score matching was performed to control for confounding. ResultsSimilar 90-day pulmonary embolism (P = 0.26), deep venous thrombosis (P = 0.67), and emergency department visit (P = 0.35) rates were found. The 90-day readmission rate for mTKA was 1.7 and 3.4% for rTKA (P = 0.08), and the overall revision rates were 2.2% for mTKA and 0.7% for rTKA (P = 0.07). Revision-free survival was 99% at one and 2 years for both groups (P = 0.65 and P = 0.43, respectively). There were no differences in the proportion of patients achieving MCID-I or MCID-W for PROMIS PF-10a, PROMIS Global – Physical, or Knee Injury and Osteoarthritis Outcome Score-Physical Function Short Form. The MCID-I for PROMIS PF-10a was achieved in 65.5 and 62.2% of patients who had mTKA and rTKA, respectively (P = 0.32). ConclusionsOur study demonstrated similar complication rates and MCID-I and MCID-W attainment rates between mTKA and rTKA patients. Future studies should assess MCID attainment rates in the long term and in larger cohorts comparing mTKA and rTKA.

End-of-Life Healthcare Utilization in Lewy Body Dementia.

Lewy body dementia (LBD) is the second most common neurodegenerative dementia in the US, presenting unique end-of-life challenges. This study examined healthcare utilization and care continuity in the last year of life in LBD. Medicare claims for enrollees with LBD, continuously enrolled in the year preceding death, were examined from 2011-2018. We assessed hospital stays, emergency department (ED) visits, intensive care unit (ICU) admissions, life-extending procedures, medications, and care continuity. We identified 45,762 LBD decedents, predominantly female (51.8%), White (85.9%), with average age of 84.1 years (SD 7.5). There was a median of 2 ED visits (IQR 1-5) and 1 inpatient stay (IQR 0-2). Higher age was inversely associated with ICU stays (Odds Ratio [OR] 0.96; 95% Confidence Interval [CI] 0.96-0.97) and life-extending procedures (OR 0.96; 95% CI 0.95-0.96). Black and Hispanic patients experienced higher rates of ED visits, inpatient hospitalizations, ICU admissions, life-extending procedures, and in-hospital deaths relative to White patients. On average, 15 (7.5) medications were prescribed in the last year. Enhanced care continuity correlated with reduced hospital (OR 0.72; 95% CI 0.70-0.74) and ED visits (OR 0.71; 95% CI 0.69-0.87) and fewer life-extending procedures (OR 0.71; 95% CI 0.64-0.79). This study underscored the complex healthcare needs of people with LBD during their final year, which was influenced by age and race. Care continuity may reduce hospital and ED visits and life-extending procedures.

Mental health service use among mothers and other birthing parents during the COVID-19 pandemic in Ontario, Canada

BackgroundParents have reported increased symptoms of depression and anxiety during the COVID-19 pandemic. This study evaluated changes in mental health and addiction (MHA)-related health service use among mothers and other birthing parents during the COVID-19 pandemic. MethodsWe conducted a repeated cross-sectional study using health administrative data in Ontario, Canada. The population included all mothers and birthing parents (≥1 child aged 1–18, no children <1 to exclude postpartum parents) between January 2016 and December 2021. We compared rates of MHA-related outpatient physician visits, hospitalizations, and emergency department (ED) visits during COVID-19 (March 2020–December 2021) to pre-COVID-19 (pre-March 2020). ResultsMHA-related outpatient visit rates increased by 17 % (rate ratio (RR) 1.17, 95 % CI 1.16–1.18) during COVID-19. Monthly utilization rates remained higher than expected across the COVID-19 period. MHA-related ED visit rates remained lower than expected during COVID-19, while MHA-related hospitalization rates returned to expected levels by August 2020. The largest relative increases in MHA-related outpatient visits during COVID-19 were in mothers and other birthing parents living in higher income (RR 1.20, 95 % CI 1.19–1.22) or urban areas (RR 1.20, 95 % CI 1.18–1.21), with children aged 1–3 years (RR 1.23, 95 % CI 1.20–1.25) and with no history of MHA-related health service use (RR 1.20, 95 % CI 1.19–1.21). LimitationsThis study only captured physician-delivered MHA-related health service use. ConclusionsThe COVID-19 pandemic was associated with an increase in MHA-related outpatient visits among mothers and other birthing parents. These findings point to the need for improvements in mental health service access.

Scheduled Follow-Up and Association with Emergency Department Use and Readmission after Trauma.

After traumatic injury, 13% to 14% of patients use the emergency department (ED) and 11% are readmitted within 30 days. Decreasing ED visits and readmission represents a target for quality improvement. This cohort study evaluates risk factors for ED visits and readmission after trauma, focusing on outpatient follow-up. We conducted a retrospective chart review of adult trauma admissions from January 1, 2018, to December 31, 2021. Our primary exposure was outpatient follow-up, primary outcome was ED use, and secondary outcome was readmission. Multivariable logistic regression evaluated the association between primary exposure and outcomes, adjusting for factors identified on unadjusted analysis. In total, 2,266 patients met inclusion criteria, with an 11.3% ED visit rate and 4.1% readmission rate. Attending follow-up did not have a significant association with ED visit (odds ratio 0.99, 95% CI 0.99 to 2.01, p = 0.05) or readmission rate (odds ratio 1.68, 95% CI 0.95 to 2.99, p = 0.08). Significant associations with ED use included non-White race, depression, anxiety, substance use disorder, discharge disposition, and being discharged with lines or drains. Significant associations with readmission included depression, anxiety, and discharge disposition. Emphasizing outpatient follow-up in trauma patients is not an effective target to decrease ED use or readmission. Future studies should focus on supporting patients with mental health comorbidities and investigating interventions to optimally engage with trauma patients after hospital discharge.

The extended impact of the COVID-19 pandemic on long-term care residents in Medicare with frailty or dual Medicaid enrollment.

Although many healthcare settings have since returned to pre-pandemic levels of operation, long-term care (LTC) facilities have experienced extended and significant changes to operations, including unprecedented levels of short staffing and facility closures, that may have a detrimental effect on resident outcomes. This study assessed the pandemic's extended effect on outcomes for LTC residents, comparing outcomes 1 and 2 years after the start of the pandemic to pre-pandemic times, with special focus on residents with frailty and dually enrolled in Medicare and Medicaid. Using Medicare claims data from January 1, 2018, through December 31, 2022, we ran over-dispersed Poisson models to compare the monthly adjusted rates of emergency department use, hospitalization, and mortality among LTC residents, comparing residents with and without frailty and dually enrolled and non-dually enrolled residents. Two years after the start of the pandemic, adjusted emergency department (ED) and hospitalization rates were lower and adjusted mortality rates were higher compared with pre-pandemic years for all examined subgroups. For example, compared with 2018-2019, 2022 ED visit rates for dually enrolled residents were 0.89 times lower, hospitalization rates were 0.87 times lower, and mortality rates were 1.17 higher; 2022 ED visit rates for frail residents were 0.85 times lower, hospitalization rates were 0.83 times lower, and mortality rates were 1.21 higher. In 2022, emergency department and hospital utilization rates among long-term residents were lower than pre-pandemic levels and mortality rates were higher than pre-pandemic levels. These findings suggest that the pandemic has had an extended impact on outcomes for LTC residents.

Racial and ethnic associations with interstitial lung disease and healthcare utilization in patients with systemic sclerosis.

Racial and ethnic differences in presentation and outcomes have been reported in systemic sclerosis (SSc) and SSc-interstitial lung disease (ILD). However, prior studies have limited diversity. We aim to evaluate if there are racial/ethnic differences associated with ILD, time intervals between SSc and ILD and with emergency department (ED) visit or hospitalization rates. Clinical and sociodemographic variables were extracted for 756 patients with SSc from longitudinal health records in an integrated health-system. Logistic regression models analyzed the association of covariates with ILD and age at SSc-ILD. Healthcare outcomes were analyzed with complementary log-log regression models. Overall, 33.7% of patients in the cohort had an ILD code, with increased odds for Asian (odds ratio [OR], 2.60; 95% confidence interval [CI], 1.29-5.28; p=0.008) compared with White patients. The predicted age in years of SSc-ILD was younger for Hispanic (estimate, -6.5; 95% CI, -13--0.21; p = 0.04) and Black/African American patients (-10; 95% CI -16--4.9; p < 0.001) compared with White patients. Black/African American patients were more likely to have an ILD code before an SSc code (59% compared with 20.6% of White patients), and the shortest interval from SSc to ILD (3 months). Black/African American (HR, 2.59; 95% CI 1.47-4.49; p = 0.001) and Hispanic patients (HR 2.29; 95% CI 1.37- 3.82; p = 0.002) had higher rates of an ED visit. We found that odds of SSc-ILD differed by racial/ethnic group, minoritized patients had earlier age of presentation, and greater rates of an ED visit.

Oral Antibiotics and Risk of Serious Cutaneous Adverse Drug Reactions

Serious cutaneous adverse drug reactions (cADRs) are potentially life-threatening drug hypersensitivity reactions involving the skin and internal organs. Antibiotics are a recognized cause of these reactions, but no studies have compared relative risks across antibiotic classes. To explore the risk of serious cADRs associated with commonly prescribed oral antibiotics, and to characterize outcomes of patients hospitalized for them. Nested case-control study using population-based linked administrative datasets among adults aged 66 years or older who received at least 1 oral antibiotic between 2002 and 2022 in Ontario, Canada. Cases were those who had an emergency department (ED) visit or hospitalization for serious cADRs within 60 days of the prescription, and each case was matched with up to 4 controls who did not. Various classes of oral antibiotics. Conditional logistic regression estimate of the association between different classes of oral antibiotics and serious cADRs, using macrolides as the reference group. During the 20-year study period, we identified 21 758 older adults (median age, 75 years; 64.1% female) who had an ED visit or hospitalization for serious cADRs following antibiotic therapy and 87 025 matched controls who did not. In the primary analysis, sulfonamide antibiotics (adjusted odds ratio [aOR], 2.9; 95% CI, 2.7-3.1) and cephalosporins (aOR, 2.6; 95% CI, 2.5-2.8) were most strongly associated with serious cADRs relative to macrolides. Additional associations were evident with nitrofurantoin (aOR, 2.2; 95% CI, 2.1-2.4), penicillins (aOR, 1.4; 95% CI, 1.3-1.5), and fluoroquinolones (aOR, 1.3; 95% CI, 1.2-1.4). The crude rate of ED visits or hospitalization for cADRs was highest for cephalosporins (4.92 per 1000 prescriptions; 95% CI, 4.86-4.99) and sulfonamide antibiotics (3.22 per 1000 prescriptions; 95% CI, 3.15-3.28). Among the 2852 case patients hospitalized for cADRs, the median length of stay was 6 days (IQR, 3-13 days), 9.6% required transfer to a critical care unit, and 5.3% died in the hospital. Commonly prescribed oral antibiotics are associated with an increased risk of serious cADRs compared with macrolides, with sulfonamides and cephalosporins carrying the highest risk. Prescribers should preferentially use lower-risk antibiotics when clinically appropriate.
