RESUMO

BACKGROUND: Dry eye disease (DED) is a disorder characterized by loss of tear film homeostasis that causes ocular surface inflammation and damage. The incidence of DED increases with age. Cyclosporine ophthalmic solution 0.09% (CEQUA®; OTX-101), cyclosporine ophthalmic emulsion 0.05% (Restasis®; CsA), and lifitegrast ophthalmic solution 5% (Xiidra®; LFT) are anti-inflammatory agents indicated for DED. This analysis compared treatment patterns in patients with DED receiving OTX-101, CsA, or LFT. METHODS: This real-world, retrospective, longitudinal cohort study utilized Symphony Health Integrated Dataverse claims from July 2019 to June 2021. The dataset included all patients with OTX-101 claims and patients with CsA or LFT claims randomly selected 2:1 to OTX-101. Patients were sorted into 3 cohorts based on index treatment. Index date was that of first treatment claim, and follow-up period was from index date to end of clinical activity or data availability. Time to treatment discontinuation (TTD), probability of discontinuation, and treatment persistence were assessed for OTX-101 vs. CsA, then OTX-101 vs. LFT. Subgroup analysis was performed based on age and prior DED treatment. Kaplan-Meier analysis and log-rank test were used to examine TTD. A logistic model evaluated association between index treatment and discontinuation. Unadjusted and adjusted odds ratios, 95% confidence intervals, and P-values were reported, with statistically significant associations based on P-values < 0.05. RESULTS: Overall, 7102 patients (OTX-101 n = 1846; CsA n = 2248; LFT n = 3008) were eligible. Median TTD was 354 days for patients receiving OTX-101 vs. 241 days for CsA and 269 days for LFT. Log-rank test indicated TTD was significantly longer for patients on OTX-101 vs. CsA (P = 0.033). Patients on CsA were 35% more likely to discontinue treatment than patients on OTX-101; OTX-101 and LFT groups had similar discontinuation rates. After 360 days, 49.8% of patients receiving OTX-101 remained on treatment vs. 39.4% of patients on CsA (P = 0.036) and 44.0% of patients on LFT (P = 0.854). CONCLUSIONS: Patients receiving OTX-101 remained on treatment significantly longer and were significantly less likely to discontinue treatment than patients on CsA. Older patients remained on OTX-101 significantly longer than CsA. These findings highlight treatment pattern differences in patients with DED receiving these anti-inflammatory agents.

RESUMO

BACKGROUND: Trifluridine/tipiracil (FTD/TPI) and regorafenib prolong survival for patients with refractory metastatic colorectal cancer (mCRC); limited comparative effectiveness data exist. MATERIALS AND METHODS: A retrospective, longitudinal cohort study of patients with mCRC who initiated FTD/TPI or regorafenib (index therapy) between 2012 and 2017 at a U.S. tertiary oncology center, Dana-Farber Cancer Institute, was conducted. Using best tumor response assessments, real-world overall response rates (rwORR) and disease control rates (rwDCR) were described and analyzed using logistic regression. Survival rate was examined for each month after index therapy using Kaplan-Meier. Overall survival (OS) was assessed using Cox proportional hazards models. Subgroup analyses among patients with index therapy as second- or third-line were performed. RESULTS: One hundred twenty-six and 95 patients were treated with FTD/TPI or regorafenib as index therapy, respectively. Patients treated with FTD/TPI versus regorafenib had a better response (rwORR 52.5% vs. 34.2%; adjusted odds ratio [OR] = 2.6; all p value <.05; rwDCR 64.2% vs. 46.1%; adjusted OR = 2.5; all p value <.05). Similar findings were observed for FTD/TPI versus regorafenib as second- or third-line therapy (rwORR 54.8% vs. 25.9%; adjusted OR = 4.1; all p value <.05; rwDCR 69.0% vs. 37.0%; adjusted OR = 4.9; all p value <.05). A greater proportion of patients treated with FTD/TPI versus regorafenib survived at 3 months (86.2% vs. 73.4%; p value = .016) and 4 months (79.6% vs. 65.8%; p value = .017). Adjusted OS hazard ratio for FTD/TPI versus regorafenib was 0.80, p value = .157. CONCLUSION: Patients treated with FTD/TPI had better tumor response and disease control than patients treated with regorafenib. Subgroup analysis in second- or third-line suggests that early use of FTD/TPI may have clinical benefits. IMPLICATIONS FOR PRACTICE: In this retrospective cohort study, patients with refractory metastatic colorectal cancer treated with trifluridine/tipiracil (FTD/TPI) were significantly less likely than those treated with regorafenib to have dose modifications and more likely to have higher real-world objective response rate (rwORR) and real-world disease control rate (rwDCR) while treated. Patients treated with FTD/TPI versus regorafenib had significantly higher odds of having rwORR or rwDCR in adjusted analyses. Monthly survival rates were higher overall in patients treated with FTD/TPI versus regorafenib in the first 6 months of follow-up, particularly at months 3 and 4. This study offers insight into patients' treatment experience in real-world clinical settings.

RESUMO

OBJECTIVES: Combination regimens of antiepileptic drugs (AEDs) with various mechanisms of action (MOA) are commonly used in patients with refractory epilepsy. However, outcomes related to combination AEDs with novel MOA, such as perampanel (PER), are not well described. This study compared healthcare resource utilization (HRU) among recipients of PER-based combinations versus recipients of other non-PER-based combinations. METHODS: This retrospective study used claims data from the Symphony Health's IDV® (Integrated Dataverse) database (August 2012 to July 2018). Patients were aged ≥12 years with epilepsy or non-febrile convulsions, were treated with AED combinations, and had ≥12 and ≥6 months pre- and post-index date, respectively (date of initiation of the second AED in the combination). AEDs were categorized based on MOA: selective non-competitive antagonist of AMPA receptors (i.e., PER), sodium channel blocker (SC), synaptic vesicle protein 2A binding (SV2), and gamma-aminobutyric acid analog (G). Patients were then classified into MOA-based cohorts: PER + SC, PER + SV2, PER + G, SC + SC, SC + SV2, SC + G, SV2 + G, and G + G. HRU outcomes were evaluated during follow-up and compared between PER-based cohorts and non-PER-based cohorts. RESULTS: On average, patients in the PER + SC (N = 3,592), PER + SV2 (N = 2,200), and PER + G (N = 1,313) cohorts were younger and had a lower Quan-Charlson comorbidity index than those in non-PER-based cohorts. PER + SC and PER + SV2 users had significantly fewer all-cause hospitalizations than non-PER-based users (adjusted RR range: 0.66-0.89, all P < 0.05), while PER + G recipients had fewer all-cause hospitalizations than recipients of SV2 + G and G + G (adjusted RR range: 0.92-0.94). Similar trends were observed for epilepsy-related hospitalizations. Across all comparisons, PER-based combinations were associated with significantly lower rates of all-cause clinic/office/outpatient visits relative to non-PER-based combinations (adjusted RR range: 0.69-0.86, all P < 0.05). SIGNIFICANCE: Results showed that patients treated with PER-based combinations had fewer all-cause and epilepsy-related hospitalizations, and fewer all-cause clinic/office/outpatient visits compared with patients treated with most other non-PER-based combinations.

RESUMO

BACKGROUND: Trifluridine and tipiracil (FTD + TPI) and regorafenib (REG) are approved treatments for the treatment of refractory metastatic colorectal cancer (mCRC). This study assesses adherence and duration of therapy with FTD + TPI versus REG and explores the effect of sequencing on adherence. MATERIALS AND METHODS: Adults diagnosed with mCRC were identified in the IQVIA Real-World Data Adjudicated Claims: U.S. database (October 2014-July 2017). The observation period spanned from the index date (first dispensing of FTD + TPI or REG) to the earliest of a switch to another mCRC agent, the end of continuous enrollment, or the end of data availability. Medication possession ratio (MPR), proportion of days covered (PDC), and persistence and time to discontinuation (gap ≥45 days) were compared between FTD + TPI and REG users and among switchers (FTD + TPI-to-REG vs. REG-to-FTD + TPI). RESULTS: A total of 469 FTD + TPI and 311 REG users were identified. FTD + TPI users had higher compliance with an MPR ≥80% (odds ratio [OR], 2.47; p < .001) and PDC ≥80% (OR, 2.77; p < .001). FTD + TPI users had better persistence (82.8% vs. 68.0%; p < .001) and lower risk of discontinuation (hazard ratio [HR], 0.76; p = .006). Among switchers (96 FTD + TPI-to-REG; 83 REG-to-FTD + TPI), those switching from FTD + TPI to REG were more likely to have an MPR ≥80% (OR, 2.91; p < .001) and PDC ≥80% (OR, 4.60; p < .001) compared with REG-to-FTD + TPI switchers while treated with these drugs. Additionally, FTD + TPI-to-REG switchers had a lower risk of first treatment discontinuation (HR, 0.66; p = .009). CONCLUSION: FTD + TPI users had significantly higher adherence and persistence, and patients who were treated with FTD + TPI before switching to REG also had higher adherence and persistence outcomes. IMPLICATIONS FOR PRACTICE: Trifluridine plus tipiracil (FTD + TPI) and regorafenib (REG) prolong survival in refractory metastatic colorectal cancer (mCRC) but have different tolerability profiles. This study assessed real-world adherence to treatment with FTD + TPI versus REG and compared outcomes among patients who switched from FTD + TPI to REG and vice versa. FTD + TPI was associated with significantly higher medication adherence and longer time to discontinuation than REG. Patients treated with FTD + TPI prior to switching to REG also showed higher adherence outcomes. Findings could help inform decision making regarding the choice and sequencing of treatment with FTD + TPI versus REG in patients with mCRC.

RESUMO

OBJECTIVE: The purpose of this study was to evaluate changes in health care resource utilization following the initiation of perampanel for the treatment of epilepsy in the United States. METHODS: Health care claims from Symphony Health's Integrated Dataverse database between December 2012 and November 2015 were analyzed. Patients newly initiated on perampanel, having ≥1 epilepsy (International Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM] code 345.xx, ICD-10-CM code G40.xxx) or nonfebrile convulsion (ICD-9-CM code 780.39, ICD-10-CM code R56.9) diagnosis, and having ≥6 months of baseline and observation periods were included. Patients <12 years old at perampanel initiation were excluded. RESULTS: Of the 2,508 perampanel patients included in the study, the mean [median] (±standard deviation [SD]) age was 35.8 [34] (±16.0) years and 56.2% were female. The mean [median] (±SD) observation duration was 459.8 [462] (±146.3) days in the postperampanel period. The postperampanel period was associated with significantly lower rates of all health care resource utilization outcomes than the pre-period. For the post- versus pre-period, perampanel users had 42.3 versus 53.8 overall hospitalizations per 100 person-years (rate ratio [RR] = 0.80, p < 0.001) and 1,240.2 versus 1,343.8 outpatient visits per 100 person-years (RR = 0.91, p < 0.001). Epilepsy-related hospitalizations and outpatient visits were 25.2 versus 33.6 per 100 person-years (RR = 0.76, p < 0.001) and 327.0 versus 389.0 per 100 person-years (RR = 0.84, p < 0.001), respectively. Additionally, a significantly lower rate of status epilepticus in the post-period (1.8 events per 100 person-years) was observed compared to the pre-period (4.4 events per 100 person-years; RR = 0.43, p < 0.001). The monthly time trend of hospitalizations showed an increasing trend leading up to the initiation of perampanel, after which the hospitalizations decreased steadily. SIGNIFICANCE: Use of perampanel for the treatment of epilepsy was associated with significant reduction in all-cause and epilepsy-related health care resource utilization, including hospitalizations, especially for status epilepticus, and outpatient visits.

RESUMO

INTRODUCTION: We analyzed the burden of illness of sporadic inclusion body myositis (sIBM) patients and the costs to the healthcare system. METHODS: A retrospective cohort analysis of 333 sIBM patients aged ≥ 50 years was performed using United States (U.S.) claims data. sIBM patients were matched in a 1:5 ratio to randomly selected individuals with ≥1 healthcare encounter within the year of index date. RESULTS: sIBM patients presented with higher rates of disease- and muscle-related conditions, such as myalgia, myositis, muscle weakness, dysphagia, pneumonia, and falls. Use of healthcare resources, including physical therapy, office visits, emergency room (ER) visits, and hospitalizations, was greater in sIBM patients. This was also reflected in significantly higher overall healthcare costs in the sIBM population driven mainly by more all-cause office visits, all-cause ER visits and hospitalizations. CONCLUSIONS: sIBM imposes a substantial burden on U.S. patients in terms of additional healthcare usage and associated costs. Muscle Nerve 56: 861-867, 2017.

RESUMO

PURPOSE: To evaluate the budget impact (BI) of adopting perampanel for adjunctive treatment of partial-onset seizures (POS), with or without secondarily generalized seizures, and the adjunctive treatment of primary generalized tonic-clonic seizures (PGTCS) in patients 12years or older in the United States. METHODS: A BI model was developed to estimate the potential BI of adopting adjunctive perampanel from a US payer (direct costs only) and societal (direct and indirect costs) perspective over a 5-year period. Efficacy data for perampanel and antiepileptic drug (AED) maintenance therapy were obtained from perampanel phase III clinical trials. Drug, direct medical (healthcare provider, emergency room, and hospitalizations), and indirect (productivity loss) costs were obtained from appropriate sources (e.g., AnalySource® Online [wholesale acquisition costs], 2013 Optum Insight Clinformatics Database [market share percentages, direct medical costs per unit], and 2011-2013 National Health and Wellness Survey [NHWS; healthcare resource utilization, overall work impairment, and baseline distribution of patients across the 4 health states]). Mapping of seizure frequency to medical resource utilization and work impairment was obtained from Kantar Health's NHWS. RESULTS: In a hypothetical health plan of 1 million members, 660 (0.066%) members ≥12years old had uncontrolled POS (395 [59.8%]) or PGTCS (265 [40.2%]). During the first 5years of adoption of perampanel, absolute BI (including drug, direct medical, and indirect costs) was $852, $2124, $3855, $5318, and $6397, respectively, for a cumulative absolute BI of $18,545. Drug cost was estimated to increase by $13,888, $34,646, $62,863, $86,728, and $104,326, respectively; however, this cost would be mostly offset by decreases in direct medical ($5041, $12,576, $22,818, $31,481, and $37,869, respectively) and indirect ($7995, $19,946, $36,190, $49,929, and $60,060, respectively) costs. Total per-member-per-month cost (drug and direct medical costs) was estimated to increase by $0.0007, $0.0018, $0.0033, $0.0046, and $0.0055 from years 1 to 5. CONCLUSIONS: Based on results of this BI model, increased cost of adopting perampanel in a health plan of 1 million members would be minimal for payers, and societal costs would be close to neutral.

RESUMO

BACKGROUND: Epilepsy is a complex disorder that can affect patients' medical, psychological, and social well-being. The purpose of this study was to evaluate the patient-reported outcome (PRO) measures of health-related quality of life (HRQoL), satisfaction, and adherence in adult patients diagnosed with epilepsy treated with perampanel in the United States (US). METHODS: A US-based, multicenter, observational cross-sectional survey was completed by 61 patients taking perampanel with or without other antiseizure medications (ASMs). Respondents were ≥18 years old, had a physician-confirmed diagnosis of epilepsy, used perampanel for ≥4 months, and provided informed consent. Patients responded to questions concerning their demographic characteristics, treatment history, experiences before perampanel, experiences while taking perampanel, HRQoL, treatment satisfaction, and medication adherence. RESULTS: Patients (N=61) were 42.8 years old on average; majority were female (63.9%) and white (75.4%). Mean time on perampanel was 2.5 years, with sodium channel blockers often (55.7%) used concomitantly with perampanel. Patients reported, on average, 5.5 (standard deviation [SD]=13.2) seizures/month after initiating perampanel, whereas these same patients reported experiencing 20.4 (SD=60.0) seizures/month prior to perampanel. When comparing their experience on perampanel with their experience with previous ASMs, more patients "strongly agreed" that perampanel allowed them to live a more normal life (36.1% vs 27.5%) and worked as intended if they missed taking a dose (16.4% vs 7.8%). Average satisfaction scores were high, with ratings of 71.8 for effectiveness, 84.0 for convenience, and 71.9 for global satisfaction (0-100 scores). Perampanel use was associated with improvements in HRQoL and fewer symptoms of depression and anxiety. The majority of patients were adherent (62.3%) to perampanel. DISCUSSION: Perampanel use was associated with reductions in number of seizures, better HRQoL, and high adherence rates. These results provide initial evidence that perampanel can be an effective, tolerable, and valid option for patients with epilepsy in the real world.

RESUMO

BACKGROUND: Trifluridine/tipiracil (FTD/TPI) and regorafenib (REG) prolong survival in refractory metastatic colorectal cancer (mCRC) and have similar indications with different side-effect profiles. The present study compared real-world treatment patterns with FTD/TPI and REG for mCRC in a large, representative US claims database. MATERIALS AND METHODS: Retrospective data from the US Symphony Health Solutions' Integrated Dataverse database were analyzed for adult mCRC patients receiving FTD/TPI or REG from October 2014 to July 2016. The index date was the first FTD/TPI or REG prescription date. The observation period spanned from the index date to the end of data collection, end of continuous clinical activity, or treatment switch. Adherence was assessed using the medication possession ratio and proportion of days covered at 3 months. The time to discontinuation was assessed over the observation period with gaps of 45, 60, or 90 days. Outcomes were compared between the cohorts using logistic regression and Cox proportional hazards models adjusting for baseline characteristic differences. RESULTS: A total of 1630 FTD/TPI patients and 1425 REG patients were identified. The FTD/TPI patients were 80% more likely to have a medication possession ratio of ≥ 0.80 compared with the REG patients (odds ratio, 1.80; P < .001) and more than twice as likely to have a proportion of days covered of ≥ 0.80 (odds ratio, 2.66; P < .001) at 3 months. The FTD/TPI patients were 37% less likely to discontinue their treatment compared with the REG patients when using the 60-day gap (hazard ratio, 0.63; P < .001). Similar results were found using the 45- and 90-day gaps. CONCLUSION: mCRC patients taking FTD/TPI were significantly more likely to adhere to and comply with therapy compared with those taking REG.

RESUMO

BACKGROUND: In Breast International Group (BIG) 1-98, a randomized, double-blind trial comparing 5 years of initial adjuvant therapy with letrozole versus tamoxifen in postmenopausal women with hormone receptor-positive early breast cancer, letrozole significantly improved disease-free survival by 19% and reduced risk of breast cancer recurrence by 28% and distant recurrence by 27%. PATIENTS AND METHODS: A Markov model was used to estimate the incremental cost per quality-adjusted life year (QALY) gained with 5 years of initial adjuvant therapy with letrozole versus tamoxifen from a US health care system perspective. Probabilities and costs of breast cancer recurrence and treatment-related adverse events and health-state utilities were based on published results of BIG 1-98 and other published studies. Costs and QALYs were estimated over the lifetime of a cohort of postmenopausal women with hormone receptor-positive early breast cancer, aged 60 years at initiation of therapy. In our base case, we assumed that benefits of letrozole on risk of breast cancer recurrence are maintained for 5 years after therapy discontinuation ("carry-over effect") and examined the effects of this assumption on results in sensitivity analyses. RESULTS: Under base-case assumptions, letrozole yields an additional 0.409 QALYs versus tamoxifen at an additional cost of $9705, yielding a cost per QALY gained for letrozole versus tamoxifen of $23,743 (95% confidence interval, $14,087-$51,129). Assuming no carry-over effects, letrozole yields 0.264 QALYs at a cost of $10,341, for a cost per QALY gained of $39,098 (95% confidence interval, $23,968- $83,501). CONCLUSION: In postmenopausal women with hormone receptor-positive early breast cancer, initial adjuvant treatment with letrozole is cost-effective from the US health care system perspective.

RESUMO

OBJECTIVE: This study assessed disruption of first-line treatments initiated after the approval of the first CDK 4/6 inhibitor, palbociclib, among post-menopausal women with HR+/HER2- metastatic breast cancer (mBC) in the US. METHODS: Post-menopausal women with HR+/HER2- mBC who initiated first-line endocrine therapy or chemotherapy (index therapy) between February 3, 2015 (palbociclib approval date) and February 29, 2016 (end of data) were identified from the Symphony Source Lx database. Patients were required to have continuous quarterly activity (defined as ≥1 pharmacy or medical claim) for 12 months prior to and 1 month after the initiation of the index therapy (index date). Treatment disruption was defined as a treatment gap of ≥60 days or adding an agent after the original therapy. Kaplan-Meier analyses were conducted to estimate treatment disruption rates during the 6 months following the index date. Patients without treatment disruption were censored at the end of continuous quarterly activity or end of data. RESULTS: A total of 8,160 and 2,153 eligible patients initiated endocrine therapy or chemotherapy as their first-line mBC treatment, with a median follow-up of 6.7 and 7.6 months, respectively. The three most prevalent metastatic sites were bone (28.1-42.2%), liver (8.8-17.3%), and lung (8.6-9.5%). Overall, 37.7% (n = 3,074) of patients receiving endocrine therapy and 86.1% (n = 1,852) of patients receiving chemotherapy encountered treatment disruption at 6 months (log-rank test p < .05). CONCLUSIONS: Treatment disruption rates of first-line therapies were sub-optimal among post-menopausal women with HR+/HER2- mBC, primarily driven by chemotherapy users. New therapies or interventions are needed to reduce treatment disruption in this patient population.

RESUMO

BACKGROUND: This study described real-world palbociclib dosing patterns and associated impacts on treatment costs for HR+/HER2- metastatic breast cancer (mBC) in the US. METHODS: Postmenopausal women with HR+/HER2- mBC who initiated palbociclib-based therapy (initiation date = index date) between 02/03/2015 (palbociclib approval) and 02/29/2016, and continuous quarterly activity 1 year before and 6 months after the index date, were identified in the Symphony Health Solutions database. Rates of 1) dose reduction (≥25 mg dose decrease/daily), and 2) reduction or interruption (>60 day gap in continuous drug supply) were assessed using Kaplan-Meier analyses. Drug wastage cost was estimated based on overlapping days between two prescription fills: the last original dose fill and the first reduced dose fill. RESULTS: 1,242 patients initiated palbociclib-based therapy (mean age = 62.7 years, median follow-up = 8.7 months). During the 12-month post-index period, across the first four lines, dose reduction rates were 31.9-33.7% and dose reduction/interruption rates were 63.5-80.9%. A total of 411 (33.1%) patients changed dose, among whom 128 (31.1%) experienced prescription fill overlap (average = 11.1 days). Mean potential drug wastage cost among patients with fill overlap was $5,471. CONCLUSIONS: Most patients receiving palbociclib experienced dose reduction or interruption early in treatment; the associated drug wastage may lead to considerable costs.

RESUMO

This study estimated the total medical cost of care and described characteristics of patients with constipation in the United States. The 2001 National Ambulatory Medical Care Survey, National Hospital Ambulatory Medical Care Survey, and National Hospital Discharge Survey were used to provide national estimates. Patients diagnosed with constipation, or whose constipation was a reason for the visit, were identified. Medicare reimbursement rates based on recognized diagnostic and procedural codes were used to value each visit related to constipation. Constipation was a diagnosis or reason for seeking care in an estimated 5.7 million ambulatory visits and was the primary diagnosis or reason for 2.7 million of those visits. Of these visits, 1,838,493 were outpatient physician, 297,927 were outpatient hospital, and 555,432 were emergency department. Constipation was the primary diagnosis in 38,361 additional inpatient visits. Total cost was dollar 235 million per year, with 55% incurred from inpatient care and 23%, 16%, and 6% from ED, outpatient physician, and outpatient hospital settings, respectively. Constipation is treated primarily in ambulatory settings, but the costs of inpatient care exceed those of ambulatory care.

RESUMO

BACKGROUND: There is a paucity of data on mortality and causes of death (CoDs) in patients with sporadic inclusion body myositis (sIBM), a rare, progressive, degenerative, inflammatory myopathy that typically affects those aged over 50 years. OBJECTIVE: Based on patient records and expertise of clinical specialists, this study used questionnaires to evaluate physicians' views on clinical characteristics of sIBM that may impact on premature mortality and CoDs in these patients. METHODS: Thirteen physicians from seven countries completed two questionnaires online between December 20, 2012 and January 15, 2013. Responses to the first questionnaire were collated and presented in the second questionnaire to seek elaboration and identify consensus. RESULTS: All 13 physicians completed both questionnaires, providing responses based on 585 living and 149 deceased patients under their care. Patients were reported to have experienced dysphagia (60.2%) and injurious falls (44.3%) during their disease. Over half of physicians reported that a subset of their patients with sIBM had a shortened lifespan (8/13), and agreed that bulbar dysfunction/dysphagia/oropharyngeal involvement (12/13), early-onset disease (8/13), severe symptoms (8/13), and falls (7/13) impacted lifespan. Factors related to sIBM were reported as CoDs in 40% of deceased patients. Oropharyngeal muscle dysfunction was ranked as the leading feature of sIBM that could contribute to death. The risk of premature mortality was higher than the age-matched comparison population. CONCLUSIONS: In the absence of data from traditional sources, this study suggests that features of sIBM may contribute to premature mortality and may be used to inform future studies.

RESUMO

Irritable bowel syndrome (IBS) is a common gastrointestinal motility disorder that typically affects persons of working age and is costly to employers. The financial burden attributable to the direct (use of healthcare resources) and indirect (missed days from work [absenteeism] and loss of productivity while at work [presenteeism]) costs of IBS is similar to that of other common long-term medical disorders, such as asthma, migraine, hypertension, and congestive heart failure. The symptoms of IBS are significantly bothersome and place a substantial burden on the personal and working lives of patients. As with other long-term medical conditions that have a significant impact on productivity, directed efforts by employers can address IBS in the workplace and thereby potentially decrease its impact. In this article, the symptoms of IBS and its impact on patients and on society as a whole are discussed; options are outlined by which employers can help reduce the total costs of IBS, including lost productivity (both absenteeism and presenteeism), in the workplace.

RESUMO

Irritable bowel syndrome (IBS) has been associated with substantial time lost from work (absenteeism) and reduced productivity at work (presenteeism), which are the indirect costs of illness. This article presents a productivity model demonstrating the indirect costs associated with IBS and the reduction in those costs for a cohort of female employees hypothetically treated with tegaserod, a new selective serotonin (5-hydroxytryptamine [5-HT]) type 4 (5-HT4) receptor agonist, which is approved by the US Food and Drug Administration for treating women with IBS-C. The model is based on economic and epidemiologic published literature and clinical trial results. In this model, tegaserod treatment resulted in 1882 dollars in avoided lost productivity per treated female employee. Considering only the benefits of decreased work loss and the costs of medical therapy, the model predicts a benefit/cost ratio of 3.75 in the base case. From an employer's perspective, medical therapy for IBS with tegaserod is cost-effective under a series of assumptions for the treatment of women with IBS with constipation.

RESUMO

Irritable bowel syndrome (IBS) is a long-term and episodic medical disorder shown to have an impact on work productivity and health-related quality of life (QOL). The objective of this study was to assess the impact of IBS on work productivity and on health-related QOL in an employed population in the United States and to quantify the cost of these factors to the employer. A 2-phase survey was sent to the workforce of a large US bank to assess the presence of IBS among employees and to measure their work productivity (absenteeism [time lost from work] and presenteeism [reduced productivity at work]) and health-related QOL. Forty-one percent of the 1776 employees responding to both phases of the survey met the Rome II criteria for IBS. Employees with IBS reported a 15% greater loss in work productivity because of gastrointestinal symptoms than employees without IBS and had significantly lower Medical Outcomes Study Short Form 36 (SF-36) scores than those without IBS. IBS was associated with a 21% reduction in work productivity, equivalent to working less than 4 days in a 5-day workweek. Employees with IBS also had significantly lower scores on all domains of the SF-36, indicating poorer functional outcomes. Reduced work productivity and diminished QOL of these magnitudes may have substantial financial impact on employers.

RESUMO

We sought to develop a budget impact model that assesses the economic effect of adding tegaserod for the management of irritable bowel syndrome (IBS) with constipation to the formulary of a managed care organization (MCO). The model estimates the per patient economic impact and the per member, per month (PMPM) economic impact of patients 6 months before and 6 months after the initiation of tegaserod. Resource utilization data, taken from medical and pharmacy administrative claims data, were based on a retrospective, longitudinal study of 3365 patients administered tegaserod through a large, geographically diverse MCO. Costs were estimated for 2 patient subgroups, women with IBS and other gastrointestinal (GI) diagnoses. Sensitivity analyses were performed by varying several model input parameters. The base-case model resulted in an incremental PMPM budget impact associated with the use of tegaserod of 0.01 dollars. Total per patient budget impact (for all resources, including tegaserod) for a 6-month period was 274.34 dollars for women with IBS and 301.84 dollars for women with other GI diagnoses. Overall, 25.9% (29.0% for women with IBS group and 21.9% for women with other GI diagnoses group) of the cost of tegaserod was offset by decreases in resource utilization. Key drivers of post-tegaserod reductions in resource costs were hospital stays, outpatient office visits, emergency department visits, endoscopic procedures, and nonendoscopic procedures. Tegaserod therapy can decrease GI-related resource utilization, resulting in a significant cost-offset percentage. When the associated budget impact of adding tegaserod to its formulary is absorbed across an entire MCO population, the PMPM impact of tegaserod is small.

RESUMO

This study sought to determine the real-world effectiveness of tegaserod therapy on gastrointestinal (GI)-related resource utilization in a managed care population with a retrospective, longitudinal pre-/post-parallel cohort study of tegaserod users and a matched reference cohort of tegaserod nonusers through medical and pharmacy claims data from a large, geographically diverse, managed care organization. Continuously enrolled benefit-eligible patients newly initiated on tegaserod therapy (index prescription) were identified between August 1, 2002, and June 30, 2003, and were categorized (using International Statistical Classification of Diseases, 9th Revision, Clinical Modification codes) as having irritable bowel syndrome (IBS) or another GI-related disorder (e.g., gastroesophageal reflux disease). GI-related resource utilization (office visits, hospitalizations, emergency department visits, endoscopic and nonendoscopic procedures, and GI drug prescriptions) was determined for the 6-month period before and after the index prescription date for tegaserod users and nonusers. The study population consisted of 3365 tegaserod users and 3364 matched nonusers. Within-cohort differences before and after therapy were tested using the Wilcoxon signed rank test. The mean age of 3365 tegaserod users and 3364 matched nonusers was 47 years (+/-15 years); 92% were women, 47% had an index diagnosis of IBS, and 53% had an index diagnosis of another GI-related disorder. Within-cohort GI resource utilization comparisons before and after therapy initiation showed significant decreases (P < .01) in all utilization categories, except GI drug prescriptions, for tegaserod users; these decreases were not consistently observed for matched nonusers. Tegaserod use appeared to be associated with consistent decreases in GI-related resource utilization after 6 months of therapy; similarly consistent reductions were not observed in tegaserod nonusers. These early findings suggest that tegaserod may provide important clinical and economic benefits.

RESUMO

BACKGROUND: The objective of this study was to measure the direct costs of treating irritable bowel syndrome (IBS) and the indirect costs in the workplace. This was accomplished through retrospective analysis of administrative claims data from a national Fortune 100 manufacturer, which includes all medical, pharmaceutical, and disability claims for the company's employees, spouses/dependents, and retirees. METHODS: Patients with IBS were identified as individuals, aged 18 to 64 years, who received a primary code for IBS or a secondary code for IBS and a primary code for constipation or abdominal pain between January 1, 1996, and December 31, 1998. Of these patients with IBS, 93.7% were matched based on age, sex, employment status, and ZIP code to a control population of beneficiaries. Direct and indirect costs for patients with IBS were compared with those of matched controls. RESULTS: The average total cost (direct plus indirect) per patient with IBS was 4527 dollars in 1998 compared with 3276 dollars for a control beneficiary (P<.001). The average physician visit costs were 524 dollars and 345 dollars for patients with IBS and controls, respectively (P<.001). The average outpatient care costs to the employer were 1258 dollars and 742 dollars for patients with IBS and controls, respectively (P<.001). Medically related work absenteeism cost the employer 901 dollars on average per employee treated for IBS compared with 528 dollars on average per employee without IBS (P<.001). CONCLUSION: Irritable bowel syndrome is a significant financial burden on the employer that arises from an increase in direct and indirect costs compared with the control group.
