BACKGROUND: Biosimilars are biologic drugs that have the potential to increase the efficiency of healthcare spending and curb drug-related cost increases. However, their introduction into hospital formularies through initiatives such as non-medical switching must be carefully orchestrated so as not to cause treatment discontinuation or result in increased health resource utilization, such as additional visits or laboratory tests, among others. This retrospective cohort study aims to assess the impact of the introduction of CT-P13 on the healthcare expenditures of patients who were treated with originator infliximab or CT-P13.
METHODS: Gastroenterology, immunoallergology and rheumatology patients treated between September 2017 and December 2020 at a university hospital in Western Switzerland were included and divided into seven cohorts, based on their treatment pathway (i.e., use and discontinuation of CT-P13 and/or originator infliximab). Costs in Swiss francs were obtained from the hospital\'s cost accounting department and length of stay was extracted from inpatient records. Comparisons of costs and length of stay between cohorts were calculated by bootstrapping.
RESULTS: Sixty immunoallergology, 84 rheumatology and 114 gastroenterology patients were included. Inpatient and outpatient costs averaged (sd) CHF 1,611 (1,020) per hospital day and CHF 4,991 (6,931) per infusion, respectively. The mean (sd) length of stay was 20 (28) days. Although immunoallergology and rheumatology patients had higher average costs than gastroenterology patients, differences in costs and length of stay were not formally explained by treatment pathway. Differences in health resource utilization were marginal.
CONCLUSIONS: The introduction of CT-P13 and the disruption of patient treatment management were not associated with differences in average outpatient and inpatient costs and length of stay, in contrast to the results reported in the rest of the literature. Future research should focus on the cost-effectiveness of non-medical switching policies and the potential benefits for patients.

BACKGROUND: Most studies on the impact of the COVID-19 pandemic on depression burden focused on the earlier pandemic phase specific to lockdowns, but the longer-term impact of the pandemic is less well-studied. In this population-based cohort study, we examined the short-term and long-term impacts of COVID-19 on depression incidence and healthcare service use among patients with depression.
METHODS: Using the territory-wide electronic medical records in Hong Kong, we identified all patients aged ≥ 10 years with new diagnoses of depression from 2014 to 2022. We performed an interrupted time-series (ITS) analysis to examine changes in incidence of medically attended depression before and during the pandemic. We then divided all patients into nine cohorts based on year of depression incidence and studied their initial and ongoing service use patterns until the end of 2022. We applied generalized linear modeling to compare the rates of healthcare service use in the year of diagnosis between patients newly diagnosed before and during the pandemic. A separate ITS analysis explored the pandemic impact on the ongoing service use among prevalent patients with depression.
RESULTS: We found an immediate increase in depression incidence (RR = 1.21, 95% CI: 1.10-1.33, p < 0.001) in the population after the pandemic began with non-significant slope change, suggesting a sustained effect until the end of 2022. Subgroup analysis showed that the increases in incidence were significant among adults and the older population, but not adolescents. Depression patients newly diagnosed during the pandemic used 11% fewer resources than the pre-pandemic patients in the first diagnosis year. Pre-existing depression patients also had an immediate decrease of 16% in overall all-cause service use since the pandemic, with a positive slope change indicating a gradual rebound over a 3-year period.
CONCLUSIONS: During the pandemic, service provision for depression was suboptimal in the face of increased demand generated by the increasing depression incidence during the COVID-19 pandemic. Our findings indicate the need to improve mental health resource planning preparedness for future public health crises.

BACKGROUND: Children in metro Shelby County, Tennessee, have disproportionally high asthma-related health care resource use (HRU) compared with those in other regions in Tennessee.
OBJECTIVE: To describe the goals, logistics, and outcomes of the Changing High-Risk Asthma in Memphis through Partnership (CHAMP) program implemented to improve pediatric asthma care in Shelby County.
METHODS: CHAMP established a multidisciplinary team with dedicated medical staff and community health workers, implemented a 24/7 call line to improve access to care, established a patient data registry to address fragmented care, assigned community health educators to improve asthma education and social needs, and partnered with services to address environmental triggers and social determinants of health. Patients eligible for CHAMP are Shelby County residents aged 2 to 18 years with high-risk asthma enrolled in Tennessee\'s Medicaid managed care program. Health care resource use outcomes 1-year pre- and post-CHAMP enrollment were analyzed for patients who had completed 1 year of CHAMP between January 2013 and December 2022. The 24/7 call line data between November 2013 and December 2022 were analyzed.
RESULTS: CHAMP has enrolled 1348 children; 945 have completed 1 year (63% male; 90% identified as Black). At 1-year post-CHAMP enrollment, patients had 58%, 68%, 42%, and 53% reductions in emergency department visits, inpatient and observation visits, urgent care visits, and total asthma exacerbations, respectively. The number of asthma exacerbations per patient significantly decreased from 2.97 to 1.40 at 1-year post-CHAMP enrollment. Of the calls made to the 24/7 call line, 58% occurred after hours and 52% led to issue resolution without a medical facility visit.
CONCLUSIONS: CHAMP successfully decreased asthma HRU in children with high-risk asthma in Shelby County by implementing initiatives that targeted barriers to asthma care.

UNASSIGNED: The objective of this systematic review was to assess the clinical, economic, and health resource utilization outcomes associated with the use of prefilled syringes in medication administration compared with traditional preparation methods.
UNASSIGNED: We conducted a systematic literature review to evaluate outcomes such as medication errors, wastage, time savings, and contamination in prefilled syringes. Our search encompassed multiple databases, including PubMed and Embase, for studies published between January 1, 2017, and November 1, 2022.
UNASSIGNED: Peer-reviewed publications meeting our inclusion criteria underwent rigorous screening, including title, abstract, and full-text article assessments, performed by two reviewers.
UNASSIGNED: Among reviewed articles, 24 met our eligibility criteria. Selected studies were primarily observational (46%) and conducted in Europe (46%). Our findings indicated that prefilled syringes consistently reduced medication errors (by 10%-73%), adverse events (from 1.1 to 0.275 per 100 administrations), wastage (by up to 80% of drug), and preparation time (from 4.0 to 338.0 seconds) (ranges varied by drug type, setting, and dosage). However, there was limited data on contamination. Economically, prefilled syringes reduced waste and error rates, which may translate into overall savings.
UNASSIGNED: This review highlights the value of prefilled syringes, which can streamline medication delivery, save nursing time, and reduce preventable medication errors. Moreover, prefilled syringes have the potential to minimize medication wastage, optimizing resource utilization and efficiency in health care settings.
UNASSIGNED: Our findings provide new insights into clinical and economic benefits of prefilled syringe adoption. These benefits include improved medication delivery and safety, which can lead to time and cost reductions for health care departments, hospitals, and health systems. However, further real-world research on clinical and economic outcomes, especially in contamination, is needed to better understand the benefits of prefilled syringes.

A phase 3 trial (ClincialTrials.gov identifier NCT02730299) of omidubicel-onlv, a nicotinamide-modified allogeneic hematopoietic progenitor cell therapy manufactured from a single umbilical cord blood (UCB) unit, showed faster hematopoietic recovery, reduced rate of infections, and shorter hospital stay compared with patients randomized to standard UCB. This prospective secondary analysis of the phase 3 trial characterized resource utilization in the first 100 days post-transplantation with omidubicel-onlv compared with UCB. This analysis examined resource utilization, including hospital length of stay, hospital care setting, visits by provider type, rate of transfusions, and readmissions, among the 108 treated patients (omidubicel-onlv, n = 52; UCB, n = 56) from day 0 to day 100 post-transplantation. Demographics were generally balanced between the 2 arms, except a higher proportion of females (52% versus 37%) and older median age (40 years versus 36 years) were noted in the omidubicel-onlv arm. Compared with patients receiving UCB transplantation, patients receiving omidubicel-onlv had a shorter average total hospital length of stay (mean, 41.2 days versus 50.8 days; P = .027) in the first 100 days post-transplantation and more days alive and out of the hospital (mean, 55.8 days versus 43.7 days; P = .023). Fewer patients died in the omidubicel-onlv arm compared with the UCB arm (12% vs 16%) before day 100 post-transplantation. During primary hospitalization (ie, time from transplantation to discharge), fewer patients receiving omidubicel-onlv required intensive care unit (ICU) admission (10% versus 23%) and spent fewer days in the ICU (mean, .4 day versus 4.7 days; P = .028) and transplant unit (mean, 25.3 days versus 32.9 days; P = .022) compared with those receiving UCB. Patients receiving omidubicel-onlv required fewer outpatient consultant and nonconsultant visits and fewer platelet or other transfusions within 100 days from transplantation. Our findings suggest that faster hematopoietic recovery in omidubicel-onlv patients is associated with significantly shorter hospital stay and reduced healthcare resource use compared with UCB.

In this review, we examine the current landscape of health resource utilization and cost-effectiveness data in the care of patient populations with immune thrombotic thrombocytopenic purpura. We focus on the therapeutic (therapeutic plasma exchange, glucocorticoids, rituximab, caplacizumab) and diagnostic (ADAMTS13 assay) health technologies employed in the care of patients with this rare disease. Health resource utilization and cost-effectiveness data are limited to the high-income country context. Measurement of TTP-specific utility weights in the high-income country context and collection of health resource utilization data in the low- and middle-income country settings would enable an evaluation of country-specific quality-adjusted life expectancy and cost-effectiveness of these therapeutic and diagnostic health technologies. This quantification of value is one way to mitigate cost concerns where they exist.

BACKGROUND: Literature on 30-day readmission in adults with sickle cell disease (SCD) is limited. This study examined the overall and age-stratified rates, risk factors, and healthcare resource utilization associated with 30-day readmission in this population.
METHODS: Using the Nationwide Readmissions Database, a retrospective cohort study was conducted to identify adult patients (aged ≥ 18) with SCD in 2016. Patients were stratified by age and followed for 30 days to assess readmission following an index discharge. The primary outcome was 30-day unplanned all-cause readmission. Secondary outcomes included index hospitalization costs and readmission outcomes (e.g., time to readmission, readmission costs, and readmission lengths of stay). Separate generalized linear mixed models estimated the adjusted odds ratios (aORs) for associations of readmission with patient and hospital characteristics, overall and by age.
RESULTS: Of 15,167 adults with SCD, 2,863 (18.9%) experienced readmission. Both the rates and odds of readmission decreased with increasing age. The SCD complications vaso-occlusive crisis and end-stage renal disease (ESRD) were significantly associated with increased likelihood of readmission (p < 0.05). Age-stratified analyses demonstrated that diagnosis of depression significantly increased risk of readmission among patients aged 18-to-29 years (aOR = 1.537, 95%CI: 1.215-1.945) but not among patients of other ages. All secondary outcomes significantly differed by age (p < 0.05).
CONCLUSIONS: This study demonstrates that patients with SCD are at very high risk of 30-day readmission and that younger adults and those with vaso-occlusive crisis and ESRD are among those at highest risk. Multifaceted, age-specific interventions targeting individuals with SCD on disease management are needed to prevent readmissions.

UNASSIGNED: Hemostatic agents are used to control surgical bleeding; however, some patients experience disruptive bleeding despite the use of hemostats. In patients receiving hemostats, we compared clinical and economic outcomes between patients with vs without disruptive bleeding during a variety of surgical procedures.
UNASSIGNED: This was a retrospective analysis of the Premier Healthcare Database. Study patients were age ≥18 with a hospital encounter for one of 9 procedures with evidence of hemostatic agent use between 1-Jan-2019 and 31-Dec-2019: cholecystectomy, coronary artery bypass grafting (CABG), cystectomy, hepatectomy, hysterectomy, pancreatectomy, peripheral vascular, thoracic, and valve procedures (first procedure = index). Patients were grouped by presence vs absence of disruptive bleeding. Outcomes evaluated during index included intensive care unit (ICU) admission/duration, ventilator use, operating room time, length of stay (LOS), in-hospital mortality, and total hospital costs; 90-day all-cause inpatient readmission was also evaluated. Multivariable analyses were used to examine the association of disruptive bleeding with outcomes, adjusting for patient, procedure, and hospital/provider characteristics.
UNASSIGNED: The study included 51,448 patients; 16% had disruptive bleeding (range 1.5% for cholecystectomy to 44.4% for valve). In procedures for which ICU and ventilator use is not routine, disruptive bleeding was associated with significant increases in the risks of admission to ICU and requirement for ventilator (all p≤0.05). Across all procedures, disruptive bleeding was also associated with significant incremental increases in days spent in ICU (all p≤0.05, except CABG), LOS (all p≤0.05, except thoracic), and total hospital costs (all p≤0.05); 90-day all-cause inpatient readmission, in-hospital mortality, and operating room time were higher in the presence of disruptive bleeding and varied in statistical significance across procedures.
UNASSIGNED: Disruptive bleeding was associated with substantial clinical and economic burden across a wide variety of surgical procedures. Findings emphasize the need for more effective and timely intervention for surgical bleeding events.

Anxiety disorders are highly prevalent and are associated with a significant humanistic and economic burden. This study evaluates the impact of anxiety symptoms on direct and indirect costs and quality of life in individuals with self-reported and unrecognized anxiety symptoms.
The 2019 US National Health and Wellness Survey database was analyzed to compare individuals with anxiety symptoms to individuals without symptoms, stratified by responses to a yes/no question about experiencing anxiety symptoms, and further stratified by severity of symptoms based on GAD-7 scores. Individuals who responded \'yes\' were characterized as having self-reported anxiety symptoms, and those who responded \'no\' were screened for unrecognized anxiety symptoms.
Overall, 44.0 % of the population experienced anxiety symptoms, of which 32.5 % self-reported experiencing anxiety, while an additional 11.5 % had mild to severe symptoms but did not self-identify as having anxiety. Both groups experienced significantly worse quality of life, and higher direct and indirect costs than a control group who had no anxiety symptoms (GAD-7 ≤ 4). Individuals with more severe anxiety symptoms experienced worse outcomes.
The data were cross-sectional, so causality could not be determined. Outcomes were based on self-report, and are therefore subject to reporting and recall bias. Prevalence and severity were assessed using the GAD-7, and not clinically validated.
A substantial proportion of the population experiences anxiety symptoms without recognizing it. Anxiety symptoms had a significant impact on quality of life, direct costs, and indirect costs, representing a considerable burden that increased with severity of illness.

Chronic cough (cough that persists for ≥ 8 weeks) can cause a range of physical symptoms and psychosocial effects that significantly impair patients\' quality of life. Refractory chronic cough (RCC) and unexplained chronic cough (UCC) are challenging to diagnose and manage, with substantial economic implications for healthcare systems.
This retrospective multicenter non-interventional study aimed to characterize the profile and health resource consumption of patients with RCC or UCC who attended outpatient clinics at Spanish hospitals. Data were collected from medical records of patients with RCC or UCC for up to 3 years before study inclusion.
The patient cohort (n = 196) was representative of the chronic cough population (77.6% female, mean age 58.5 years). Two-thirds of patients (n = 126) had RCC. The most frequently visited doctors were pulmonologists (93.4% of patients) and primary care physicians (78.6%), with a mean of 5 visits per patient over three years\' observation. The most common diagnostic tests were chest x-ray (83.7%) and spirometry with bronchodilation (77.0%). The most commonly prescribed treatments were proton pump inhibitors (79.6%) and respiratory medications (87.8%). Antibiotics were prescribed empirically to 56 (28.6%) patients. Differences between RCC or UCC groups related mainly to approaches used to manage cough-associated conditions (gastroesophageal reflux disease, asthma) in patients with RCC.
RCC and UCC are responsible for high health resource utilization in Spanish hospitals. Specific treatments targeting the pathological processes driving chronic cough may provide opportunities to reduce the associated burden for patients and healthcare systems.
