Treatment costs for patients with Streptococcus suis infection in Northern Thailand: a hospital-based observational study of 14-year data

BackgroundStreptococcus suis (S.suis) is a neglected zoonotic disease that imposes a significant economic burden on healthcare and society. To our knowledge, studies estimating the cost of illness associated with S.suis treatment are limited, and no study focuses on treatment costs and potential key drivers in Thailand. This study aimed to estimate the direct medical costs associated with S.suis treatment in Thailand and identify key drivers affecting high treatment costs from the provider’s perspective.MethodsA retrospective analysis of the 14-year data from 2005–2018 of confirmed S.suis patients admitted at Chiang Mai University Hospital (CMUH) was conducted. Descriptive statistics were used to summarize the data of patients’ characteristics, healthcare utilization and costs. The multiple imputation with predictive mean matching strategy was employed to deal with missing Glasgow Coma Scale (GCS) data. Generalized linear models (GLMs) were used to forecast costs model and identify determinants of costs associated with S.suis treatment. The modified Park test was adopted to determine the appropriate family. All costs were inflated applying the consumer price index for medical care and presented to the year 2019.ResultsAmong 130 S.suis patients, the average total direct medical cost was 12,4675 Thai baht (THB) (US$ 4,016), of which the majority of expenses were from the “others” category (room charges, staff services and medical devices). Infective endocarditis (IE), GCS, length of stay, and bicarbonate level were significant predictors associated with high total treatment costs. Overall, marginal increases in IE and length of stay were significantly associated with increases in the total costs (standard error) by 132,443 THB (39,638 THB) and 5,490 THB (1,715 THB), respectively. In contrast, increases in GCS and bicarbonate levels were associated with decreases in the total costs (standard error) by 13,118 THB (5,026 THB) and 7,497 THB (3,430 THB), respectively.ConclusionsIE, GCS, length of stay, and bicarbonate level were significant cost drivers associated with direct medical costs. Patients’ clinical status during admission significantly impacts the outcomes and total treatment costs. Early diagnosis and timely treatment were paramount to alleviate long-term complications and high healthcare expenditures.

Healthcare Resource Utilization and Cost Burden of BCG-Treated Non-Muscle Invasive Bladder Cancer Patients in Germany: A Retrospective Claims Analysis.

Intermediate and high-risk non-muscle-invasive bladder cancer (NMIBC) is typically managed with transurethral resection of the bladder tumour (TURBT) followed by intravesical Bacillus Calmette-Guérin (BCG) immunotherapy; however, NMIBC patients can become refractory or unresponsive to BCG treatment, and/or progress to muscle-invasive bladder cancer (MIBC). Healthcare resource utilization (HCRU) and costs in these patient populations are high. A retrospective longitudinal cohort design of adult (≥18 years) patients with bladder cancer and BCG treatment (01/01/2012-31/12/2017) was conducted using data from a representative subset of the German statutory health insurance database. During the follow-up period after last BCG, patients were categorized into subgroups of No further NMIBC treatment, Continuous treatment for NMIBC, or MIBC evidence; HCRU and costs were tabulated for each subgroup and for the entire cohort. A total of 1049 patients met the study inclusion criteria (mean age, 70.9 years; 84.8% male). Across the different subgroups, patients showing MIBC evidence had more than two times higher hospitalization rates compared to the other subgroups. Overall, the entire BCG-treated cohort's total direct medical cost including hospitalizations, outpatient care and drugs was €33.9 million and €9250 per patient-year. Cost for patients with MIBC evidence was much higher, at €17,983 per patient-year, than patients with No further NMIBC treatment (€6617) and patients with Continuous treatment for NMIBC (€7786). Across the subgroups, hospitalization was the largest driver of cost and contributed the most to cost for those with MIBC evidence. The overall cost burden of this BCG-treated cohort of 1049 patients is high (€38 million whereof 4.1 million are indirect costs) over a mean follow-up of 3.9 years; economic burden is especially substantial for patients who fail BCG treatment and those who progress.

Perioperative Analgesics and Anesthesia as Risk Factors for Postoperative Chronic Opioid Use in Patients Undergoing Total Knee Arthroplasty: A Retrospective Cohort Study Using Japanese Hospital Claims Data.

Patients with chronic postsurgical pain are commonly prescribed opioids chronically because of refractory pain although chronic opioid use can cause various severe problems. We aimed to investigate postoperative chronic opioid use and its association with perioperative pain management in patients who underwent a total knee arthroplasty in a Japanese real-world clinical setting. We conducted a retrospective cohort study using an administrative claims database. We used a multivariate logistic regression analysis to examine the association between perioperative analgesic and anesthesia prescriptions and postoperative chronic opioid use. We calculated all-cause medication and medical costs for each patient. Of the 23,537,431 patient records, 14,325 patients met the criteria and were included in the analyses. There were 5.4% of patients with postoperative chronic opioid use. Perioperative prescriptions of weak opioids, strong and weak opioids, and the α2δ ligand were significantly associated with postoperative chronic opioid use (adjusted odds ratio [95% confidence interval], 7.22 [3.89, 13.41], 7.97 [5.07, 12.50], and 1.45 [1.13, 1.88], respectively). Perioperative combined prescriptions of general and local anesthesia were also significantly associated with postoperative chronic opioid use (3.37 [2.23, 5.08]). These medications and local anesthesia were more commonly prescribed on the day following surgery, after routinely used medications and general anesthesia were prescribed. The median total direct costs were approximately 1.3-fold higher among patients with postoperative chronic opioid use than those without postoperative chronic opioid use. Patients who require supplementary prescription of analgesics for acute postsurgical pain are at high risk of postoperative chronic opioid use and these prescriptions should be given careful consideration to mitigate the patient burden.

Determinants of Cost for Outpatient Hysterectomy for Benign Indications in a Nationwide Sample.

To identify surgeon-level variation in cost to produce an outpatient hysterectomy for benign indications in the United States. A sample of patients undergoing outpatient hysterectomy in October 2015 to December 2021, excluding those with a diagnosis of gynecologic malignancy, was obtained from the Vizient Clinical Database. The primary outcome was total direct hysterectomy cost, which is a modeled cost to produce care. Patient, hospital, and surgeon covariates were analyzed with mixed-effects regression, which included surgeon-level random effects to capture unobserved differences influencing cost variation. The final sample included 264,717 cases performed by 5,153 surgeons. The median total direct cost of hysterectomy was $4,705 (interquartile range $3,522-6,234). Cost was highest for robotic hysterectomy ($5,412) and lowest for vaginal hysterectomy ($4,147). After all variables were included in the regression model, approach was the strongest of the observed predictors, but 60.5% of the variance in costs was attributable to unexplained surgeon-level differences, implying a difference in costs between the 10th and 90th percentiles of surgeons of $4,063. The largest observed determinant of cost to produce an outpatient hysterectomy for benign indications in the United States is approach, but differences in cost are attributable primarily to unexplained differences among surgeons. Standardization of surgical approach and technique and surgeon awareness of surgical supply costs could address these unexplained cost variations.

Direct Medical Costs and Accordance of INA-CBG's Claims on Covid-19 Patients at Anutapura Hospital

Background: The pandemic Covid-19 has had an impact on various aspects of life, both socially and economically. One of the government's responsibilities is in financing the treatment of Covid-19 patients, which is stated in the Decree of the Minister of Health of the Republic of Indonesia Number HK.01.07/MENKES/5673/2021 regarding technical instructions for claiming the cost of Covid-19 services. Objectives: This study aimed to determine the average direct medical costs and according to the INA-CBGs rates for Covid-19 patients and the effect of length of stay, severity and comorbidities on the total cost from a hospital perspective. Material and Methods: This study was an observational descriptive study, used a sample of patients diagnosed with Covid-19 inpatients at Anutapura Hospital Palu in 2020. The sample was used 134 patients, who met the inclusion and exclusion criteria. The data collected includes patient characteristics, direct medical costs (consultation fees, visits, rooms, medical procedures, medical devices, examinations and drugs) and INA-CBGS rates. Results: the Covid-19 patients were hospitalized for 14 days (65.67%) with severe severity (92.54%), patients without comorbidities (comorbidities) (74.63%) and included in the group with INA-CBGs code was A-4-13-III (92.54%). The average direct medical cost of the patient was Rp. 5,371,333, with the largest cost being the room fee, which was 32.57% of the total cost. The average INA-CBG's tariff was Rp. 123,019,851. Conclusions: The INA-CBGs tariff was higher than direct medical costs with a difference of Rp. 117,648,518. The results of the linear regression test, it was found that there was a partial or simultaneous effect between length of hospitalization, severity and incidence of comorbidities on total direct medical costs.

Updated estimate of the annual direct medical cost of screening and treatment for human papillomavirus associated disease in the United States.

The annual direct medical cost attributable to human papillomavirus (HPV) in the United States over the period 2004-2007 was estimated at $9.36 billion in 2012 (updated to 2020 dollars). The purpose of this report was to update that estimate to account for the impact of HPV vaccination on HPV-attributable disease, reductions in the frequency of cervical cancer screening, and new data on the cost per case of treating HPV-attributable cancers. Based primarily on data from the literature, we estimated the annual direct medical cost burden as the sum of the costs of cervical cancer screening and follow-up and the cost of treating HPV-attributable cancers, anogenital warts, and recurrent respiratory papillomatosis (RRP). We estimated the total direct medical cost of HPV to be $9.01 billion annually over the period 2014-2018 (2020 U.S. dollars). Of this total cost, 55.0% was for routine cervical cancer screening and follow-up, 43.8% was for treatment of HPV-attributable cancer, and less than 2% was for treating anogenital warts and RRP. Although our updated estimate of the direct medical cost of HPV is slightly lower than the previous estimate, it would have been substantially lower had we not incorporated more recent, higher cancer treatment costs.

Economic Burden of Cervical and Head and Neck Cancer in Taiwan from a Societal Perspective.

Head and neck cancers (HNC) are increasingly recognized as important human papillomavirus (HPV)-related malignancies in addition to cervical cancer (CC). However, data on the socioeconomic impact of HNC and CC in Taiwan are limited. A retrospective cohort study was conducted to estimate the total direct medical cost and indirect productivity loss from CC and HNC between 2014 and 2015. Patient data from the Taiwan National Cancer Registry were analyzed, with matched non-cancer controls from the Taiwan National Healthcare Reimbursement Database. Indirect costs due to premature deaths were calculated using public data from Taiwanese government reports. In the direct cost analysis, 2083 patients with newly diagnosed CC and 11,078 with newly diagnosed HNC (10,036 males) were identified between 2014 and 2015 and followed up through the end of 2016 or until death. The total direct medical costs incurred in 2014 and 2015 due to HNC were 11.54 times higher in males than in females, and 4.55 times higher than CC. Indirect cost analysis showed the total annual productivity loss was New Taiwan Dollar (NTD) $12 billion in 2019, and 79.99% was attributed to male HNC. In Taiwan, the socioeconomic burden associated with male HNC is high and greater than that seen with CC. While not all HNCs are attributable to HPV infection, prevention of HNC through HPV vaccination should be considered for both sexes.

Economic burden of type 2 diabetes in Iran: A cost-of-illness study.

Type 2 diabetes mellitus (T2DM) is a prevalent public health problem worldwide, and the economic burden of the disease poses one of the main challenges for health systems in low- and middle-income countries. This study aimed to estimate the economic burden of T2DM in Iran, in 2018. This was a cost-of-illness study. Three hundred and seventy-five patients with T2DM who were referred to Imam Reza and Sina's educational and therapeutic centers and Asad Abadi clinic in Tabriz, Iran, in 2018 were included. A researcher-constructed checklist was used for data collection. Data were analyzed using EXCEL and SPSS software version 22. Total economic burden of diabetes was estimated at 152,443,862,480.3 (purchasing power parity[PPP], Current International $) (approximately 7.69% of GDP, PPP, Current International $). The mean total direct and indirect costs were 11,278.68 (PPP) (62.35% of mean total cost) and 6808.88 (PPP, Current International $) (37.64% of the total cost), respectively. The mean total direct medical cost and the direct nonmedical cost were 10,819.43 (PPP, Current International $) (59.81% of mean total cost) and 459.24 (PPP, Current International $) (2.53% of mean total cost) per patient, respectively. Besides, the mean direct medical cost was 6.18 times the total per capita expenditure on health, and the total direct medical cost was 8.9% times the total expenditure on health. Diabetes imposes a substantial economic burden on patients, health systems, and the whole economy. Besides, since the cost of the disease in patients treated with insulin and those with diabetes complications is significantly higher, the reinforcement of self-care measures and focusing on modifying lifestyle (dietary modification and physical activity) in patients with T2DM can significantly reduce the costs of the disease.

Healthcare Scheme to Overcome Financial Burden Associated with Chemoradiation Therapy in Head and Neck Cancer Patients: A Retrospective Single Centre Study.

Head and neck cancer (HNC) is third highest prevalent cancer among Indian which constitutes about 25-30% of all the cancer in India. Further, out-of-pocket expenditure (OOPE) covers around 67% of total healthcare expenditure and direct medical cost is key factor responsible for raised OOPE in India. Thus, we aimed to quantify total direct medical cost and OOPE associated with HNC management among HNC patients using "Ayushman Bharat Arogya Karnataka scheme" (ABArK scheme). A retrospective study was conducted for the duration of 6 months to collect the data related to total direct medical cost, coverage of "ABArK Scheme" and OOPE of past 2 years of HNC patients. The data of HNC patients above 18 years of age utilizing "ABArK scheme" were included in the study whereas data of patients utilizing other healthcare schemes and incomplete data on target schemes were excluded. A total of 196 patients (54.1%) utilized the "ABArK Scheme" out of 362 HNC patients treated in past 2 years. Among 196 patients, males (76.5%) were predominant over females (23.5%) with the mean age of 53.60 ± 11.58 years. We found that INR 17,370,279 as the total direct medical expenditure for the management of HNC patients of which around 87.465% was covered by "ABArK Scheme" minimizing the OOPE up to INR 3,297,970. Thus, Introduction and implementation of novel healthcare policies like "ABArK Scheme" can counteract financial burden of cancer management by significantly reducing OOPE which could be milestone achievement for the low-middle income countries like India.

Assessing challenges and opportunities of treating breast cancer in Lesotho

Background: It has been estimated that, more than 60% of the new breast cancer cases and 70% of related deaths will be seen in Low-Middle Income Countries in the coming 20 years. In Lesotho, out of 228 women, 177 had heard about breast cancer while 72.9% had heard of breast cancer screening. Given limited treatment facilities and options in Lesotho, many patients die soon after diagnosis, before they are able to access treatment; to date this cannot be quantified. Another challenge that affects breast cancer management is treatment and travel-related costs, particularly for those not living close to the medical centre. Most patients are coming with advanced disease stage and are sent home for home-based care, some of which could have been prevented with early screening. Aim: The aim of study is to determine challenges faced by breast cancer patients, the cost to the health system and the opportunities this may bring to the country. Methods: A quantitative cross-sectional, prospective and retrospective study was conducted on 45 breast cancer patients who were initiated chemotherapy at the only cancer treatment centre in Lesotho; Senkatana oncology clinic located at the Botshabelo complex in Maseru. Results: The majority of patients were facing challenges of arranging transport to the doctor (83.3%, n=15), of being far from the healthcare facilities even if transportation was available (77.8%, n=14), paying for healthcare (83.3%, n=15), paying for transport (77.8%, n=14) and paying for diagnostic test (88.9%, n=16) in all ages. Majority of patients who presented for care and treatment late faced challenges more than those who presented earlier. Diagnostic and monitoring laboratory test constituted 64.5% of total direct medical costs followed by 24.7 % from chemotherapy. Conclusion: The challenges faced by breast cancer patients are of financial and practical nature and they get higher for patients who presented at advanced stage for care and treatment. In order to improve breast cancer care and treatment outcome at lower costs efforts for breast cancer awareness need to be intensified so that patients presented early at the health centers. In term of direct medical cost, the largest cost came from the diagnostic and monitoring laboratory tests.

Out-of-pocket expenditure on non-communicable diseases during Covid-19. A cross-sectional study from a semi-urban area of Kannur, Kerala

IntroductionNon-communicable disease (NCD) care was drastically affected during the COVID-19 pandemic. Therefore, this study aimed to estimate the cost incurred for NCD care during the pandemic and also to compare the cost of care of private and public facility utilizers. MethodsThis community-based cross-sectional analytical study was conducted among 316 individuals aged 30 years and above from selected primary care facility service areas in Kannur district, Kerala. The total cost of illness for all NCDs was calculated from the patient's perspective and was estimated using a bottom-up approach. Direct, indirect, and total costs were summarized using the median with IQR. A median regression analysis was done to find the factors associated with total cost. ResultsThe total median direct medical cost was ₹400.0 (120–2360.0), and the total median direct non-medical cost was ₹720.0 (300.0–1200.0). The total median cost of NCD care was ₹1200.0.0 (200.0–3990.0). There was a significant association between the place of NCD service utilization and cost. The cost of availing care from private [₹2497.5 (455.0–6490.0)] was much higher compared to public facilities [₹120.0 (0–1000.0)]. ConclusionThe expenditure on NCD care during COVID-19 was high and for a private facility utilizer, it was much higher compared to a government facility utilizer. Strengthening the services through subcentres can reduce travel expenses, hence the non-medical cost of NCD care.

Pharmacotherapy Analysis for Hospitalized Patients with COVID-19 (Prescriptions, Costs, and Outcomes)

Background: The COVID-19 pandemic has caused many economic problems worldwide, in Iran as well, causing Hospitals to face many financial problems. Objectives: Based on documented data on pharmacotherapy, costs, and its effectiveness, this study aimed to analyze the costs and outcomes of hospitalized patients with COVID-19 under pharmacotherapy in Iran. Methods: This research was a retrospective analytical descriptive study. Relevant data of the COVID-19 hospitalized patients’ were extracted from the Hospital’s Medical Records Department. All items of direct medical costs, such as visits, nursing services, consuming materials, laboratories, imaging, medical operations, medications, and beds, were extracted by reviewing COVID-19 hospitalized patients’ files in different wards of the Shohada Ashayer Hospital in Khorramabad city in 2021. Results: A total of 399 patients were examined in this study. The total direct medical costs per patient was 338.63 US$. Of note, the highest cost was related to medicine (32.56%), more than the cost of bed (22.77%). The most commonly used drugs were Lopinavir (95%) and Azithromycin (90%), and the highest medicine cost per patient was related to Immunoglobulin (64.32 US$) and Remdesivir (46.91 US$). Conclusion: Medicine and hospitalization costs accounted for the largest share of the total treatment costs of patients. Therefore, reducing bed costs requires home treatments and outpatient injections. Furthermore, due to rising drug costs, prescriptions should be based on standard treatment protocols.

Lyme borreliosis in Belgium: a cost-of-illness analysis

BackgroundLyme borreliosis (LB) is the most common tick-borne disease in Europe and North America, yet its economic burden remains largely unknown. This study aimed to estimate the economic cost associated with the different clinical manifestations of LB in Belgium.MethodsAn incidence approach and societal perspective were used to estimate the total cost-of-illness for LB in Belgium. Costs were calculated for patients with erythema migrans (EM) or disseminated/late LB, including patients who developed post-treatment Lyme disease syndrome (PTLDS). Direct medical, direct non-medical (transportation & paid help) and indirect non-medical costs (productivity losses) were included in the analysis. Ambulatory cost data were collected through a prospective cohort study from June 2016 to March 2020, in which patients with LB were followed up 6 to 12 months after diagnosis. Hospitalization costs were retrieved from the Minimal Clinical Data registry, a mandatory registry for all Belgian hospitals, linked to the Minimal Financial Data registry. Costs were expressed in 2019 euros.ResultsThe total annual cost associated with clinical manifestations of LB in Belgium was estimated at €5.59 million (95% UI 3.82–7.98). Of these, €3.44 million (95% UI 2.05–5.48) or 62% was related to disseminated/late LB diagnoses and €2.15 million (95% UI 1.30–3.26) to EM. In general, direct medical costs and productivity losses accounted for 49.8% and 46.4% of the total costs, respectively, while direct non-medical costs accounted for only 3.8%. The estimated mean costs were €193 per EM patient and €5,148 per disseminated/late LB patient. While patients with PTLDS seemed to have somewhat higher costs compared to patients without PTLDS, the number of patients was too small to have representative estimates.ConclusionsWe estimate the total annual direct medical costs, direct non-medical and indirect non-medical costs associated with LB to exceed €5.5 million per year, almost evenly distributed between EM (40%) and disseminated/late LB (60%). EM costs 26 times less per patient but occurs also 16 times more frequently than disseminated/late LB. The cost burden remains limited by comparison to other infectious diseases due to the relative lower incidence.

Clinical and economic burden of drug-susceptible tuberculosis in Indonesia: national trends 2017–19

The global incidence of tuberculosis is decreasing, yet it remains high in Indonesia. The Indonesian National Tuberculosis Program facilitates mandatory notification, which enables early detection and treatment, minimises complications, prevents transmission, and decreases deaths. This study aimed to assess the characteristics, trends, and economic burden of notified drug-susceptible tuberculosis cases registered in this system from 2017 to 2019. We performed a multiyear cross-sectional study focusing on drug-susceptible tuberculosis notified cases, incidence, geographical tuberculosis case distribution, treatment outcomes, and costs in Indonesia using data from Sistem Informasi Tuberkulosis (2017-19). The settings were Indonesian health-care facilities that provide tuberculosis control programmes and services. Eligible patients were those who were diagnosed with drug-susceptible tuberculosis and notified to Sistem Informasi Tuberkulosis. Between 2017 and 2019, notified cases increased from 429 219 to 523 614 individuals, corresponding to an increase in incidence from 167 cases per 100 000 to 196 cases per 100 000. In 2019, more than 250 cases per 100 000 inhabitants were notified in Jakarta, North Sulawesi, Gorontalo, and Papua. Treatment success rate increased from 363 098 (84·60%) of 429 219 in 2017 to 452 966 (86·51%) of 523 614 in 2019, with a relatively stable mortality, changing from 3·15% to 3·05%. HIV status was increasingly confirmed, with unknown status decreasing from 66·21% to 43·68%. The costs of visits and monitoring and drug regimens were relatively stable, with total direct medical costs slightly increasing from US$39·40 to $40·40 per case. Progress was made on drug-susceptible tuberculosis management in Indonesia. However, further intensified efforts, including case-finding, optimising diagnosis, and cost-effective tuberculosis management are required if Indonesia is to achieve the 2025 WHO End Tuberculosis Strategy target incidence of fewer than 55 cases per 100 000 people. These data are an important starting point for understanding drug-susceptible tuberculosis dynamics in Indonesia and optimising its management.

Significant healthcare burden and life cost of spinal muscular atrophy: real-world data.

The aim of this study is to quantify the mortality rate, direct healthcare costs, and cumulative life costs of pediatric patients with spinal muscular atrophy (SMA) type 1, type 2, and type 3 born in Hong Kong. Data were collected from genetically confirmed SMA patients born in or after 2000 from the Hospital Authority medical database. Patients were followed up from birth until they died, left Hong Kong, reached 18years, or initiated disease-modifying treatment. Study outcomes included incidence risks of mortality, cumulative direct medical costs-attendances of special outpatient clinics, emergency department, allied health services, and mean length of stay in hospitals over time. Total direct medical costs were calculated as unit costs multiplied by utilization frequencies of corresponding healthcare services at each age. Seventy-one patients with SMA were included. Over a median follow-up period of 6years, the overall incidence rate of death was 5.422/100 person-years (95%CI 3.542-7.945/100 person-years). 67.7% and 11% of deaths occurred in SMA1 and SMA2 groups, respectively. The median age of death was 0.8years in SMA1 and 10.9years in SMA2. The mean cumulative direct medical costs in overall SMA, SMA1, SMA2 and SMA3 groups per patient were US$935,570, US$2,393,250, US$413,165, and US$40,735, respectively. Our results confirmed a significantly raised mortality and extremely high healthcare burden for patients with SMA especially SMA type 1 and 2 without disease-modifying treatment. Study evaluating health and economic impact of newborn screening and early treatment is needed.

Adherence, Persistence, Readmissions, and Costs in Medicaid Members with Schizophrenia or Schizoaffective Disorder Initiating Paliperidone Palmitate Versus Switching Oral Antipsychotics: A Real-World Retrospective Investigation.

Long-acting injectable antipsychotic agents have been suggested to improve adherence and patient outcomes in schizophrenia or schizoaffective disorder. The purpose of this study was to assess medication use patterns (i.e., medication adherence, persistence), hospital and emergency department readmissions, and total direct medical costs of Oklahoma Medicaid members with schizophrenia or schizoaffective disorder switching from an oral antipsychotic (OAP) to once-monthly paliperidone palmitate (PP1M) or to another OAP (OAP-switch). A historical cohort analysis was conducted from 1 January 2016 to 31 December 2020 among adults aged ≥ 18 and ≤ 64years with schizophrenia or schizoaffective disorder who were previously treated with an OAP. The first claim for PP1M or a new OAP defined the study index date. Members who transitioned from PP1M to 3-month formulation (PP3M) were included (i.e., PP1M/PP3M). Proportion of days covered (PDC), 45-day treatment gaps, 30-day readmissions to hospitals or emergency department, and total direct medical costs were assessed using multivariable, machine-learning least absolute shrinkage, and selection operator (Lasso) regressions controlling for numerous demographic, clinical, mental health, and provider characteristics. Among 295 Medicaid members meeting full inclusion criteria, 183 involved PP1M/PP3Ms (44 PP1M cases transitioned to PP3M) and 112 involved an OAP-switch. The multivariable-adjusted odds of readmission were significantly associated with a 45-day treatment gap (p < 0.05) and non-adherence (i.e., PDC < 80%) (p < 0.05). Relative to PP1M/PP3Ms, the multivariable analyses also indicated that OAP-switch was associated with an 18.5% lower PDC, 92.3% higher number of 45-day treatment gaps, and an approximately 90% higher odds of all-cause 30-day readmission (p < 0.05). The adjusted pre- to post-index change in cost was approximately 49% lower for OAP-switches versus PP1M/PP3Ms (p < 0.001), although unadjusted post-index costs did not differ between groups (p = 0.440). This real-world investigation of adult Medicaid members with schizophrenia or schizoaffective disorder observed improved adherence and persistence with fewer readmissions with PP1M/PP3Ms versus OAP-switches.

ALLERGY-RELATED HEALTHCARE RESOURCE USE AND COSTS IN PATIENTS WITH MULTIPLE VERSUS SINGLE FOOD ALLERGIES

<h3>Introduction</h3> Clinical and economic burden associated with food allergy and allergic diseases is not well characterized, particularly for patients with multiple food allergies (MFA). We explore healthcare resource utilization (HRU) and annual cost estimates of those living with food allergy (FA). <h3>Methods</h3> Patients with ≥1 insurance claim for FA or anaphylactic reaction due to food in 2015-2018, and with continuous enrollment in a health plan ≥12 months before and after the first FA/reaction (index) were identified from the US MarketScan claims databases. Single FA (SFA) cases were defined as those having only 1 documented food allergen (excluding allergy to an unknown food); MFA cases were those with >1 document food allergen. The associations between MFA and 1-year post-index allergy-related HRU and costs were estimated using multivariable regression analysis. <h3>Results</h3> Patients with MFA (N=32,595) and SFA (N=94,802) had mean(SD) age of 11(12) and 20(18) years and were 43% and 52% female. For MFA/SFA cohorts, annual incidences of allergy-related hospitalizations were 2.7%/2.5%, emergency department visits were 16%/11%, and outpatient visits were 80%/54%. After baseline adjustment and compared with SFA, MFA was associated with greater likelihood of: allergy-related hospitalizations (odds ratio [OR][95%CI]: 1.42[1.30,1.55]); emergency department visits (OR[95%CI]: 1.84[1.76,1.91]); outpatient visits (incidence rate ratio: 1.27[1.26,1.28]), p<0.001). In the MFA/SFA cohorts, the estimated 1-year total direct medical costs (95%CI) were $1103 ($1045,$1160)/$760 ($727,$793), respectively. <h3>Conclusion</h3> Allergy-related clinical and economic burden is high in patients with FA, and greater in patients with MFA compared with SFA, highlighting unmet need for treatment and disease management.

Cost-effectiveness and cost-utility of add-on, low-dose prednisolone in patients with rheumatoid arthritis aged 65+: The pragmatic, multicenter, placebo-controlled GLORIA trial

BackgroundThe GLORIA placebo-controlled trial found a favorable balance of benefit and harm for two years of prednisolone (5 mg/day) as add-on treatment for rheumatoid arthritis (RA) patients aged 65+. This study evaluated the cost-effectiveness of low-dose prednisolone in the treatment of RA. MethodsThe economic evaluation had a societal perspective with a time horizon of two years. Cost data were collected with questionnaires and from recorded events, and valued with standard Dutch unit prices of 2017. The primary effectiveness outcome was the disease activity score in 28 joints (DAS28). For cost-utility, quality-adjusted life years (QALYs) were estimated from the EuroQol-5 Dimension (EQ-5D) questionnaire. Bootstrapping assessed the uncertainty around the average differences in costs and health outcomes. ResultsIn total, 444 of 451 randomized patients were included in the modified intention-to-treat analysis. Patients had median four active comorbidities at baseline. Mean total costs over two years were k€10.8 in the prednisolone group, k€0.5 (95% CI –4.0; 1.8) lower than in the placebo group. Total direct medical costs were k€0.5 (95% CI –4.0; 1.5) lower in the prednisolone group. The mean number of QALYs was similar in both groups (difference 0.02 [–0.03; 0.06] in favor of prednisolone). The DAS28 was 0.38 lower in the prednisolone group than in the placebo group (0.19; 0.56). ConclusionWith greater effectiveness (DAS28) at non-significantly lower costs, low-dose, add-on prednisolone is cost-effective for RA compared to placebo over two years. QALYs were equal in both groups, most likely due to the impact of multiple comorbidities.

Cost-effectiveness of insulin degludec/insulin aspart versus biphasic insulin aspart in Chinese population with type 2 diabetes.

To evaluate the long-term cost effectiveness of insulin degludec/insulin aspart (IDegAsp) vs. biphasic insulin aspart 30 (BIAsp 30) for the treatment of people with type 2 diabetes mellitus (T2DM) inadequately managed on basal insulin in China. The CORE (the Center for Outcomes Research) Diabetes Model, which has been published and verified, was used to simulate disease progression and calculate the total direct medical costs, life years (LYs) and quality-adjusted life years (QALYs) over 30 years, from the perspective of Chinese healthcare system. The patient demographic information and clinical data needed for the model were gathered from a phase III treat-to-target clinical trial (NCT02762578) and other Chinese cohort studies. Medical costs on treating diabetes were calculated based on clinical trial and local sources. The diabetes management and complications costs were derived from published literature. A discounting rate of 5% was applied to both health and cost outcomes. And one-way and probabilistic sensitivity analyses were carried out to test the reliability of the results. Compared with BIAsp 30, treatment with IDegAsp was associated with an incremental benefit of 0.001 LYs (12.439 vs. 12.438) and 0.280 QALYs (9.522 vs. 9.242) over a 30-year time horizon, and increased CNY (Chinese Yuan) 3,888 (390,152 vs. 386,264) for total costs. IDegAsp was cost-effective vs. BIAsp 30 therapy with an incremental cost-effectiveness ratio of CNY 13,886 per QALY gained. Results were robust across a range of sensitivity analyses. Compared with BIAsp 30, IDegAsp was a cost-effective treatment option for people with T2DM with inadequate glycemic management on basal insulin in China.

The economic burden of low back pain in KwaZulu-Natal, South Africa: A prevalence-based cost-of-illness analysis from the healthcare provider's perspective.

Low back pain (LBP) is a multifactorial and the most prevalent musculoskeletal disorder, whose economic burden is of global concern. Evidence suggests that the burden of LBP in increasing and will continue rising with the greatest burden occurring in low-and-middle-income-countries (LMICs). This study sought to determine the economic burden of LBP in KwaZulu-Natal, South Africa from the providers perspective. We used a retrospective prevalence-based cost-of-illness methodology to estimate the direct medical cost of LBP. Direct medical costs constituted costs associated with healthcare utilisation in inpatient care, outpatient care, investigations, consultations, and cost of auxiliary devices. We used diagnostic-specific data obtained from hospital clinical reports. All identifiable direct medical costs were estimated using a top-down approach for costs associated with healthcare and a bottom-up approach for costs associated with inpatient and outpatient care. The prevalence of chronic low back pain CLBP was 24.3% (95% CI: 23.5-25.1). The total annual average direct medical costs associated with LBP was US$5.4 million. Acute low back pain (ALBP) and CLBP contributed 17% (US$0.92 million) and 83% (US$4.48 million) of the total cost, respectively. The per patient total annual average direct medical cost for ALBP and CLBP were US$99.43 and US$1,516.67, respectively. The outpatient care costs contributed the largest share (38.9%, US$2.10 million) of the total annual average direct medical cost, 54.9% (US$1.15 million) of which was attributed to nonsteroidal-anti-inflammatory drugs (NSAIDs). The total average cost of diagnostic investigations was estimated at US$831,595.40, which formed 15.4% of the average total cost. The economic burden of LBP is high in South Africa. Majority of costs were attributed to CLBP. The outpatient care costs contributed the largest share percent of the total cost. Pain medication was the main intervention strategy, contributing more than half of the total outpatient costs. Measures should be taken to ensure guideline adherence. Focus should also be placed towards development of prevention measures to minimise the cost.
