Impact of COVID-19 pandemic on depression incidence and healthcare service use among patients with depression: an interrupted time-series analysis from a 9-year population-based study.

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.

Age-related differences in risks and outcomes of 30-day readmission in adults with sickle cell disease.

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). CONCLUSION: 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.

Assessing the Clinical, Economic, and Health Resource Utilization Impacts of Prefilled Syringes Versus Conventional Medication Administration Methods: Results From a Systematic Literature Review.

OBJECTIVE: 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. DATA SOURCES: 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. STUDY SELECTION AND DATA EXTRACTION: Peer-reviewed publications meeting our inclusion criteria underwent rigorous screening, including title, abstract, and full-text article assessments, performed by two reviewers. DATA SYNTHESIS: 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. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE: 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. CONCLUSION AND RELEVANCE: 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.

Characteristics and Management of Patients with Refractory or Unexplained Chronic Cough in Outpatient Hospital Clinics in Spain: A Retrospective Multicenter Study.

PURPOSE: 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. METHODS: 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. RESULTS: 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. CONCLUSION: 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.

The impact of bone mineral density screening on incident fractures and healthcare resource utilization among postmenopausal breast cancer survivors treated with aromatase inhibitors.

Bone mineral density screening prior to initiating aromatase inhibitor therapy was associated with lower incident bone fractures and healthcare resource utilization among postmenopausal breast cancer survivors. INTRODUCTION: Postmenopausal women with hormone receptor-positive breast cancer (BC) often receive aromatase inhibitor (AI) therapy. However, AIs induce bone loss and BC survivors are at an increased risk of bone fractures. This study determined whether receipt of baseline dual-energy x-ray absorptiometry (DXA) screening is associated with decreased incident fractures and lower healthcare resource utilization. METHODS: We retrospectively analyzed 22,713 stage 0-III primary BC survivors who received AI therapy ≤ 1 year prior to BC diagnosis from the Medicare-Linked Surveillance, Epidemiology, and End-Results database. We categorized DXA screening for those who had a procedural claim within 12 months prior through 6 months after first AI claim. We used propensity score methods to assess the association of DXA screening with bone fractures and health resource utilization. RESULTS: Of the study cohort, 62% received a DXA screening. Women with comorbid dementia, renal disease, and congestive heart failure were less likely to receive a DXA. After adjusting for confounders, BC survivors who received a DXA had a 32% decreased risk of any bone fracture compared to those who did not (hazard ratio (HR): 0.68, 95% confidence interval (CI): 0.60-0.76, p < 0.001). Similarly, those who received a DXA were less likely to be hospitalized (HR 0.73 (0.62-0.86)) or use outpatient services (HR 0.85 (0.74-0.97)). CONCLUSIONS: Bone density screening is associated with decreased incident bone fractures and a lower likelihood of utilizing healthcare resource for fracture-related events. Postmenopausal BC survivors treated with AIs should undergo appropriate bone density screening to reduce morbidity, mortality, and health care expenses.

Clinical and societal burden of incident major depressive disorder: A population-wide cohort study in Stockholm.

OBJECTIVE: Major depressive disorder (MDD) is a highly prevalent condition and a significant contributor to global disability. The vast majority of MDD is handled by primary care, but most real-life studies on MDD only include data from secondary care. The aim of this study was therefore to estimate the total clinical and societal burden of incident MDD including data from all healthcare levels in a large well-defined western European healthcare region. METHODS: Population-wide observational study included healthcare data from Region Stockholm, Sweden's largest region with approximately 2.4 million inhabitants. All patients in Region Stockholm having their first unipolar MDD episode between January 1, 2012, and December 31, 2018, were included. The sample also included matched study population controls. Outcomes were psychiatric and non-psychiatric comorbid conditions, antidepressant therapy use, healthcare resource utilization, work loss, and all-cause mortality. RESULTS: In the study period, 137,822 patients in Region Stockholm were diagnosed with their first unipolar MDD episode. Compared with matched controls, MDD patients had a higher burden of non-psychiatric and psychiatric comorbid conditions, 3.2 times higher outpatient healthcare resource utilization and 8.6 times more work loss. MDD was also associated with a doubled all-cause mortality compared with matched controls (HR: 2.2 [95% CI: 2.0-2.4]). CONCLUSIONS: The high mortality, morbidity, healthcare resource utilization, and work loss found in this study confirms that MDD is associated with individual suffering and low functioning leading to substantial costs for patients and society. These findings should motivate additional efforts in improving outcomes for MDD patients.

Burden of influenza hospitalization among high-risk groups in the United States.

BACKGROUND: Seasonal influenza poses a substantial clinical and economic burden in the United States and vulnerable populations, including the elderly and those with comorbidities, are at elevated risk for influenza-related medical complications. METHODS: We conducted a retrospective cohort study using the IQVIA PharMetrics® Plus claims database in two stages. In Stage 1, we identified patients with evidence of medically-attended influenza during influenza seasons from October 1, 2014 to May 31, 2018 (latest available data for Stage 1) and used a multivariable logistic regression model to identify patient characteristics that predicted 30-day influenza-related hospitalization. The findings from Stage 1 informed high-risk subgroups of interest for Stage 2, where we selected cohorts of influenza patients during influenza seasons from October 1, 2014 to March 1, 2019 and used 1:1 propensity score matching to patients without influenza with similar high-risk characteristics to compare influenza-attributable rates of all-cause hospital and emergency department (ED) visits during follow-up (30-day and in the index influenza season). RESULTS: In Stage 1, more than 1.6 million influenza cases were identified, of which 18,509 (1.2%) had a hospitalization. Elderly age was associated with 9 times the odds of hospitalization (≥65 years vs. 5-17 years; OR = 9.4, 95% CI 8.8-10.1) and select comorbidities were associated with 2-3 times the odds of hospitalization. In Stage 2, elderly influenza patients with comorbidities had 3 to 7 times higher 30-day hospitalization rates compared to matched patients without influenza, including patients with congestive heart failure (41.0% vs.7.9%), chronic obstructive pulmonary disease (34.6% vs. 6.1%), coronary artery disease (22.8% vs. 3.8%), and late-stage chronic kidney disease (44.1% vs. 13.1%; all p < 0.05). CONCLUSIONS: The risk of influenza-related complications is elevated in the elderly, especially those with certain underlying comorbidities, leading to excess healthcare resource utilization. Continued efforts, beyond currently available vaccines, are needed to reduce influenza burden in high-risk populations.

The Child & Youth CompreHensIve Longitudinal Database for Deep Brain Stimulation (CHILD-DBS).

PURPOSE: Deep brain stimulation (DBS) is a common tool for the treatment of movement disorders in adults; however, it remains an emerging treatment modality in children with a growing number of indications, including epilepsy and dystonia. The Child & Youth CompreHensIve Longitudinal Database of DBS (CHILD-DBS) study aims to prospectively collect relevant data on quality of life (QoL), safety, efficacy, and long-term neurodevelopmental outcomes following DBS in children. METHODS: Data are collected and managed using the Research Electronic Data Capture (REDCap). This database aims to collect multicentre comprehensive and longitudinal clinical, QoL, imaging and electrophysiologic data for children under the age of 19 undergoing DBS. RESULTS: Both general and indication-specific measures are collected at baseline and at four time points postoperatively: 6 months, 1 year, 2 years, and 3 years. The database encompasses QoL metrics for children, including the PedsQL (Pediatric Quality of Life Inventory, generic), QOLCE (Quality of Life in Childhood Epilepsy Questionnaire, parent-rated), CHU 9D (Child Health Utility 9D), and KIDSCREEN. Caregiver clinical and QoL metrics, including QIDS (Quick Inventory of Depressive Symptomatology), GAD-7 (Generalized Anxiety Disorder 7-item scale), and CarerQoL-7D (The Care-related Quality of Life Instrument), are similarly prospectively collected. Healthcare resource utilization is also assessed before and after DBS. Lastly, stimulation parameters and radiographic and electrophysiologic data are collected within the database. CONCLUSIONS: The development of the current prospective paediatric DBS database with carefully selected physical and psychosocial outcomes and assessments will complement existing efforts to enhance and facilitate multisite collaboration to further understand the role of DBS in childhood.

Patterns and predictors of opioid use among migraine patients at emergency departments: A retrospective database analysis.

OBJECTIVES: To compare medication use and health resource utilization between migraineurs with evidence of opioid use at emergency department visit versus no opioid use at emergency department visit, and to examine predictors of opioid use among migraineurs at emergency department visits. METHODS: This was a retrospective study using REACHnet electronic health records (December 2013 to April 2017) from Baylor Scott & White Health Plan. The index date was defined as the first migraine-related emergency department visit after ≥6 months of enrollment. Adult patients with a migraine diagnosis and ≥6 months of continuous enrollment before and after their index dates were included. Descriptive statistics and bivariate analyses were used to compare medication use and health resource utilization between opioid users and non-opioid users. Multivariable logistic regression was used to examine predictors of opioid use at emergency department visits. RESULTS: A total of 788 migraineurs met eligibility criteria. Over one-third (n = 283, 35.9%) received ≥1 opioid medication during their index date emergency department visit. Morphine (n = 103, 13.1%) and hydromorphone (n = 85, 10.8%) were the most frequently used opioids. Opioid users had more hospitalizations and emergency department visits during their pre-index period (both p < 0.05). Significant (p < 0.05) predictors of opioid use at emergency department visits included past migraine-related opioid use (2-4 prescriptions, Odds Ratio = 1.66; 5-9 prescriptions, Odds Ratio = 2.12; ≥10 prescriptions, Odds Ratio = 4.43), past non-migraine-related opioid use (≥10 prescriptions, Odds Ratio = 1.93), past emergency department visits (1-3 visits, Odds Ratio = 1.84), age (45-64 years, Odds Ratio = 1.45), and sleep disorder (Odds Ratio = 1.43), controlling for covariates. CONCLUSION: Opioids were commonly given to migraineurs at emergency departments. Previous opioid use, health resource utilization, age, and specific comorbidities might be used to identify migraineurs with a high risk of opioid use.

Informing Targeted Interventions to Optimize the Cascade of HIV Care Using Cluster Analyses of Health Resource Use Among People Living with HIV/AIDS.

Increased awareness of the secondary preventive benefits of antiretroviral treatment (ART) has strengthened the desire to optimize health care systems' response to HIV/AIDS. We identified clusters of health resource utilization (HRU) among people living with HIV (PLHIV) to inform targeted interventions aimed to optimize the cascade of HIV care. Using linked population-level health databases in British Columbia, Canada, we selected two analytic samples of PLHIV with 3 years of follow-up between 2006-2011 that were classified as intermittently retained in care or intermittently engaged in ART, and executed a probabilistic model-based clustering analysis for each sample with 5 and 9 quarterly HRU variables, respectively. We found clear HRU profile differences among both samples with similar HIV-related care: one featured active involvement in non-HIV care, the other little or no health care interaction following linkage to care. Differential reengagement intervention strategies capitalizing on missed opportunities in non-HIV care and further engaging physicians delivering HIV care are needed to optimize the response to the HIV epidemic.

Endoscopic ultrasound for rectal cancer staging: A population-based study of utilization, impact on treatment patterns, and survival.

BACKGROUND AND AIM: Optimal rectal cancer (RC) outcomes depend on accurate locoregional staging. The study sought to describe the impact of endoscopic ultrasound (EUS) on RC treatment patterns and survival. METHODS: Using the Surveillance, Epidemiology, and End Results-Medicare database, the study identified patients with RC between 2005 and 2007. The study excluded patients with stage IV disease, those not enrolled in Medicare parts A and B, those enrolled in managed care, and those staged with pelvic magnetic resonance imaging (because of low numbers). The study then compared outcomes between patients who received EUS and computed tomography of the abdomen and pelvis (CTAP) to those staged with CTAP alone after propensity score matching. RESULTS: Between 2005 and 2007, we identified 3,408 nonmetastatic RC patients. Compared with patients staged with CTAP alone, those who received EUS and CTAP were younger (median age: 75 vs 76 years, P < 0.0001), more likely men (57.6% vs 48.7%, P < 0.0001), with a lower Charlson comorbidity index (P < 0.0001). Predictors of EUS included socioeconomic status (highest vs lowest) (odds ratio [OR] 1.87, 95% confidence interval [CI] 1.4-2.5), care by a gastroenterologist (OR 1.713, 95% CI 1.38-2.13), and care in a teaching hospital (OR 1.68, 95% CI 1.35-2.08). Receipt of neoadjuvant chemoradiation was higher in EUS-staged patients (50.3% vs 16.0%, P < 0.0001). EUS-staged patients had longer overall survival compared with those staged with CTAP alone (60 vs 57 months), but this was not statistically significant (P = 0.24). CONCLUSION: Endoscopic ultrasound in RC staging is associated with higher utilization of neoadjuvant chemoradiation without a significant difference in overall survival.

Estimating asthma control questionnaire (ACQ) scores from claims data.

BACKGROUND: Asthma control is the main focus of treatment guidelines. Valid instruments such as the Asthma Control Questionnaire (ACQ) require prospective survey. These surveys may be challenging for large population health applications. OBJECTIVE: To develop an algorithm for estimating ACQ-5 scores from commonly available claims data. METHODS: Data was derived from four prospective surveys including the ACQ-5 combined with retrospective claims of Kaiser Permanente of Colorado (KPCO) patients. The statistical approach consisted of derivation and validation of a prediction algorithm including medical and pharmacy claims data using stepwise regression elimination. Validation was conducted by estimating mean squared error (MSE) and mean absolute error (MAE) in one hundred split-sample iterations. Ordinary least squares (OLS), Tobit and Median regression were used. RESULTS: There were 2,657 individuals with valid ACQ-5 scores, claims and eligibility at baseline. The following had statistically significant associations with ACQ-5 scores: gender, use of oral corticosteroids and short-acting beta agonists, the number of asthma drug classes, and emergency and outpatient visits. Average MSE and MAE were similar for the estimation and validation samples. CONCLUSION: This research provides preliminary results of the feasibility of predicting ACQ-5 scores using commonly available medical and pharmacy claims data. The resulting algorithm may facilitate public health and population level analyses of asthma control. Future studies in different populations will be important to validate the algorithm.

Impact of plerixafor (mozobil) on hospital efficiency: A single center experience.

Plerixafor (Mozobil) in combination with granulocyte colony-stimulating factor (G-CSF) has shown to increase mobilization of peripheral blood stem cells (PBSC) as compared to G-CSF alone in patients undergoing autologous stem cell transplantation (ASCT). However, up to 25% of patients treated with G-CSF alone still fail mobilization. Adding plerixafor to poor mobilizers allows to rescue these patients from mobilization failure and to reduce the number of apheresis sessions. The goal of this retrospective study was to capture the impact of plerixafor on treatment outcome and on apheresis department efficiency. The latter was measured in terms of time-slots lost, that is, the number of apheresis sessions scheduled but not carried out due to poor mobilization, and the number of elective apheresis sessions performed for patients undergoing extracorporeal photopheresis (ECP). Hospital records of patients treated before and after introduction of plerixafor were collected and analyzed. With plerixafor, the mobilization failure rate dropped from 12% to 4% and the mean number of time-slots lost per patient dropped from 1.39 to 0.89. Additional drug costs due to plerixafor were partially balanced by a reduction in apheresis sessions, resulting in an additional cost of 759€ per ASCT candidate. More importantly, with the use of plerixafor, the availability of time-slots turned from erratic to predictable such that freed capacity could be dedicated to other apheresis procedures. As a result, the number of ECP sessions increased from 0 in 2005 to 685 sessions in 2014.

Health-Related Quality of Life and Health Resource Utilization in Patients with Primary Immunodeficiency Disease Prior to and Following 12 Months of Immunoglobulin G Treatment.

PURPOSE: Health-related quality of life (HRQOL) has not been examined in patients with predominant antibody deficiency both pre- and post-immunoglobulin G (IgG) treatment initiation. HRQOL and health resource utilization (HRU) were assessed in newly diagnosed patients with primary immunodeficiency disease (PIDD) pre- and 12 months post-IgG treatment initiation. METHODS: Adults (age ≥18 years) completed the 36-item Short Form Health Survey, version 2; pediatric patients (PP)/caregivers completed the Pediatric Quality of Life Inventory (PedsQL). Scores were compared with normative data from the US general population (GP) and patients with other chronic conditions (OCC). RESULTS: Seventeen adult patients (APs), 8 PPs, and 8 caregivers completed baseline assessments. APs had significantly lower baseline mean physical component summary scores versus GP (37.4 vs 50.5, p < 0.01) adults with chronic back pain (44.1, p < 0.05) or cancer (44.4, p < 0.05) and lower mental component summary scores versus GP (41.6 vs 49.2, p < 0.05). PPs had lower PedsQL total (63.1 vs 82.7), physical summary (64.5 vs 84.5), and psychosocial summary (62.5 vs 81.7) scores versus GP. Post-IgG treatment, 14 APs, 6 PPs, and 8 caregivers completed assessments. Hospital admissions (0.2 versus 1.8, p < 0.01), serious infections (3.3 versus 10.9, p < 0.01) and antibiotic prescriptions (3.0 versus 7.1; p < 0.01) decreased significantly overall. While APs reported significant improvement in role-physical (p = 0.01), general health (p < 0.01), and social functioning (p = 0.02) and caregivers in vitality (p < 0.01), PPs did not. CONCLUSIONS: Pre-IgG treatment, patients with PIDD experienced diminished HRQOL versus GP and patients with OCC; post-treatment, HRU decreased and certain HRQOL aspects improved for APs and caregivers.

Cognitive status is a determinant of health resource utilization among individuals with a history of falls: a 12-month prospective cohort study.

SUMMARY: Falls are a costly public health problem worldwide. The literature is devoid of prospective data that identifies factors among fallers that significantly drive health care resource utilization. We found that cognitive function--specifically, executive functions--and cognitive status are significant determinants of health resource utilization among older fallers. INTRODUCTION: Although falls are costly, there are no prospective data examining factors among fallers that drive health care resource utilization. We identified key determinants of health resource utilization (HRU) at 6 and 12 months among older adults with a history of falls. Specifically, with the increasing recognition that cognitive impairment is associated with increased falls risk, we investigated cognition as a potential driver of health resource utilization. METHODS: This 12-month prospective cohort study at the Vancouver Falls Prevention Clinic (n = 319) included participants with a history of at least one fall in the previous 12 months. Based on their cognitive status, participants were divided into two groups: (1) no mild cognitive impairment (MCI) and (2) MCI. We constructed two linear regression models with HRU at 6 and 12 months as the dependent variables for each model, respectively. Predictors relating to mobility, global cognition, executive functions, and cognitive status (MCI versus no MCI) were examined. Age, sex, comorbidities, depression status, and activities of daily living were included regardless of statistical significance. RESULTS: Global cognition, comorbidities, working memory, and cognitive status (MCI versus no MCI ascertained using the Montreal Cognitive Assessment (MoCA)) were significant determinants of total HRU at 6 months. The number of medical comorbidities and global cognition were significant determinants of total HRU at 12 months. CONCLUSION: MCI status was a determinant of HRU at 6 months among older adults with a history of falls. As such, efforts to minimize health care resource use related to falls, it is important to tailor future interventions to be effective for people with MCI who fall.

The association of lung function and St. George's respiratory questionnaire with exacerbations in COPD: a systematic literature review and regression analysis.

BACKGROUND: This study investigated the relationship between changes in lung function (as measured by forced expiratory volume in one second [FEV1]) and the St. George's Respiratory Questionnaire (SGRQ) and economically significant outcomes of exacerbations and health resource utilization, with an aim to provide insight into whether the effects of COPD treatment on lung function and health status relate to a reduced risk for exacerbations. METHODS: A systematic literature review was conducted in MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials to identify randomized controlled trials of adult COPD patients published in English since 2002 in order to relate mean change in FEV1 and SGRQ total score to exacerbations and hospitalizations. These predictor/outcome pairs were analyzed using sample-size weighted regression analyses, which estimated a regression slope relating the two treatment effects, as well as a confidence interval and a test of statistical significance. RESULTS: Sixty-seven trials were included in the analysis. Significant relationships were seen between: FEV1 and any exacerbation (time to first exacerbation or patients with at least one exacerbation, p = 0.001); between FEV1 and moderate-to-severe exacerbations (time to first exacerbation, patients with at least one exacerbation, or annualized rate, p = 0.045); between SGRQ score and any exacerbation (time to first exacerbation or patients with at least one exacerbation, p = 0.0002) and between SGRQ score and moderate-to-severe exacerbations (time to first exacerbation or patients with at least one exacerbation, p = 0.0279; annualized rate, p = 0.0024). Relationships between FEV1 or SGRQ score and annualized exacerbation rate for any exacerbation or hospitalized exacerbations were not significant. CONCLUSIONS: The regression analysis demonstrated a significant association between improvements in FEV1 and SGRQ score and lower risk for COPD exacerbations. Even in cases of non-significant relationships, results were in the expected direction with few exceptions. The results of this analysis offer health care providers and payers a broader picture of the relationship between exacerbations and mean change in FEV1 as well as SGRQ score, and will help inform clinical and formulary-making decisions while stimulating new research questions for future prospective studies.

Switching from Cigarettes to Heated Tobacco Products in Japan-Potential Impact on Health Outcomes and Associated Health Care Costs.

BACKGROUND: Japan's rising health expenditure, driven by an aging population, coincides with growing demands for increased spending. Reducing smoking-related costs could alleviate the burden on the health care system. Despite efforts to promote smoking cessation, success has been limited, indicating a need for strategies beyond cessation. METHODS: Using a status quo simulation based on hospital resource data from the Japanese Ministry of Health, Labor, and Welfare, we examine the impact of heated tobacco products (HTPs) on the prevalence of four smoking-attributable diseases (chronic obstructive pulmonary disease, ischemic heart disease, stroke, and lung cancer) and the related direct health care costs. The baseline scenario assumes a 50% switch from combustible cigarettes to HTPs, with a 70% risk reduction. A sensitivity analysis was conducted to assess the effects of parameter variations. RESULTS: If 50% of smokers replaced combustible tobacco products with HTPs, 12 million patients could be averted equivalent to JPY 454 billion in health care savings. Prefectures located in the north and south of Japan would benefit the most. CONCLUSIONS: Considering the heterogeneous prevalence rates, a one-size-fits-all tobacco control approach is ineffective. Japan should prioritize cost-efficient measures that promote public health and economic benefits. Encouraging smokers to switch to reduced-risk products, raising awareness of health risks, and adopting a harm-based taxation model can drive positive change. Public-private partnerships can further enhance harm reduction efforts. With a combination of tax reforms, revised regulations, collaborations, and ongoing research, Japan can create a more effective and comprehensive approach to tobacco control.

Does the introduction of an infliximab biosimilar always result in savings for hospitals? A descriptive study using real-world data.

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.

Clinical and Economic Burden Associated with Disruptive Surgical Bleeding: A Retrospective Database Analysis.

Background: 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. Methods: 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. Results: 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. Conclusion: 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.

The burden of anxiety among a nationally representative US adult population.

BACKGROUND: 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. METHODS: 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. RESULTS: 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. LIMITATIONS: 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. CONCLUSION: 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.
