Abstract

Objectives:

This study aimed to examine the real-world healthcare resource utilization (HCRU) and direct costs among chronic bronchitis (CB) patients treated with chronic obstructive pulmonary disease (COPD) maintenance medications.

Methods:

This retrospective analysis utilized administrative claims data from 14 US commercial managed care plans. Eligible patients were ≥40 years old, had ≥2 years of continuous enrollment, ≥1 CB (ICD-9-CM code 491.xx) hospitalization or emergency department (ED) visit or ≥2 office visits between 1/1/2004 and 5/31/2011, and had ≥2 pharmacy fills for COPD medications during follow-up (first fill served as the index date). All-cause and COPD-related HCRU and costs were assessed during follow-up. Multivariate models were utilized to identify predictors of total costs.

Results:

Treated CB patients (n?=?17,382; 50.6% female; mean age 66.7 (SD?=?11.4) years) had a mean of 7.6 (SD?=?6.3) COPD maintenance medication fills during follow-up. Overall, 32.6% of patients had ≥1 COPD-related inpatient hospitalizations, 12.9% had ≥1 ED visit, and 81.8% had ≥1 office visit. Mean all-cause and COPD-related total costs were $25,747 (SD?=?$51,105) and $12,609 (SD?=?$36,801), respectively, during follow-up. Among the sub-group with ≥1 exacerbation during baseline year, 42.3% had ≥1 COPD-related inpatient hospitalization, 18.5% had ≥1 ED visit, and 88.2% had ≥1 office visit. Mean follow-up all-cause and COPD-related total costs were $29,861 (SD?=?$49,799) and $16,784 (SD?=?$34,170), respectively. The number of baseline exacerbations was a significant predictor of all-cause and COPD-related total costs during follow-up.

Limitations:

This study lacked standard measures of CB severity; however, severity proxies were utilized.

Conclusion:

HCRU and costs among CB patients were substantial during follow-up, despite treatment with COPD maintenance medications. Additional interventions aiming to prevent or reduce HCRU and costs among CB patients warrant exploration.  相似文献

Abstract

Purpose: This study aimed to evaluate the healthcare resource utilization (HCRU) and costs for patients with severe aplastic anemia (SAA) using US claims data.

Methods: This retrospective, observational database study analyzed claims data from the Truven MarketScan databases. SAA patients aged ≥2?years identified between 2014 and 2017 who were continuously enrolled for 6?months before their first SAA treatment or blood transfusion, with a ≥6-month follow-up, were included. Baseline demographics and comorbidities were evaluated. Monthly all-cause and SAA-related HCRU and direct costs in the follow-up period were analyzed and differences were presented for all patients and across age groups.

Results: With an average follow-up period of 21.5?months, 939 patients were included in the study. Monthly all-cause and SAA-related HCRU [mean (SD)] were 1.65 days (2.61 days) and 0.18 days (0.70 days) for length of stay, 0.18 (0.23) and 0.01 (0.04) for hospital admissions, 0.25 (0.30) and 0.02 (0.07) for ER visits, 2.24 (1.40) and 0.46 (0.99) for office visits, and 2.90 (2.64) and 0.55 (1.31) for outpatient visits, respectively. On average, SAA patients received 0.15 (0.57) blood transfusions per month. Mean monthly all-cause direct costs were $28,280 USD ($36,127) [US dollars, mean (SD)]. Direct costs related to admissions were $11,433 USD (SD $25,040), followed by $624 USD ($1,703) for ER visits, $528 USD ($694) for office visits, $7,615 USD ($13,273) for outpatient visits, and $5,998 USD ($11,461) for pharmacy expenses. Monthly SAA-related direct costs averaged $7,884 USD (SD $16,254); of these costs, $1,608 USD ($7,774) were from admissions, $47 USD ($257) from ER visits, $127 USD ($374) from office visits, $1,462 USD ($4,994) from outpatient visits, and $4,451 USD ($10,552) from pharmacy expenses.

Conclusion: SAA is associated with high economic burden, with costs comparable to blood malignancies, implying that US health plans should consider appropriately managing SAA while constraining the total healthcare costs when making formulary decisions.  相似文献

Abstract

Aims: The current study examined the association between insufficient major depressive disorder (MDD) care and healthcare resource use (HCRU) and costs among patients with prior myocardial infarction (MI) or stroke.

Methods: This was a retrospective study conducted using the MarketScan Claims Database (2010–2015). The date of the first MI/stroke diagnosis was defined as the cardiovascular disease (CVD) index date and the first date of a subsequent MDD diagnosis was the index MDD date. Adequacy of MDD care was assessed during the 90 days following the index MDD date (profiling period) using 2 measures: dosage adequacy (average fluoxetine equivalent dose of ≥20?mg/day for nonelderly and ≥10?mg/day for elderly patients) and duration adequacy (measured as the proportion of days covered of 80% or higher for all MDD drugs). Study outcomes included all-cause and CVD-related HCRU and costs which were determined from the end of the profiling period until the end of study follow-up. Propensity-score adjusted generalized linear models (GLMs) were used to compare patients receiving adequate versus inadequate MDD care in terms of study outcomes.

Results: Of 1,568 CVD patients who were treated for MDD, 937 (59.8%) were categorized as receiving inadequate MDD care. Results from the GLMs suggested that patients receiving inadequate MDD care had 14% more all-cause hospitalizations, 4% more all-cause outpatient visits, 17% more CVD-related outpatient visits, 13% more CVD-related emergency room (ER) visits, higher per patient per year CVD-related hospitalization costs ($21,485 vs. $17,756), higher all-cause outpatient costs ($2,820 vs. $2,055), and higher CVD-related outpatient costs ($520 vs. $434) compared to patients receiving adequate MDD care.

Limitations: Clinical information such as depression severity and frailty, which are potential predictors of adverse CVD outcomes, could not be ascertained using administrative claims data.

Conclusions: Among post-MI and post-stroke patients, inadequate MDD care was associated with a significantly higher economic burden.  相似文献

Abstract

Objective:

To evaluate chronic obstructive pulmonary disease (COPD)-related expenditure and hospitalisation in COPD patients treated with tiotropium versus alternative long-acting bronchodilators (LABDs).

Methods:

Data were from the Thomson Reuters MarketScan Research Databases. COPD patients ≥35 years with at least one LABD claim between July 1, 2004 and June 30, 2006 were classified into five cohorts based on index LABD: monotherapy with tiotropium, salmeterol/fluticasone propionate, formoterol fumarate, or salmeterol or combination therapy. Demographic and clinical characteristics were evaluated for a 6-month pre-period and COPD-related utilisation and total costs were evaluated for a 12-month follow-up period. LABD relationship to COPD-related costs and hospitalisations were estimated by multivariate generalised linear modelling (GLM) and multivariate logistic regression, respectively.

Results:

Of 52,274 patients, 53% (n?=?27,457) were male, 71% (n?=?37,271) were ≥65?years, and three LABD cohorts accounted for over 90% of the sample [53% (n?=?27,654) salmeterol/fluticasone propionate, 23% (n?=?11,762) tiotropium, and 15% (n?=?7755) combination therapy]. Patients treated with salmeterol/fluticasone propionate (p?<?0.001), formoterol fumarate (p?=?0.032), salmeterol (p?=?0.004), or with combination therapy (p?<?0.001) had higher COPD-related costs and a greater risk of inpatient admission (p?<?0.01 for all) versus tiotropium.

Limitations:

These data are based on administrative claims and as such do not include clinical information or information on risk factors, like smoking status, that are relevant to this population.

Conclusions:

Patients treated with tiotropim had lower COPD-related expenditures and risk of hospitalisation than patients treated with other LABDs  相似文献

Abstract

Objectives:

To describe treatment patterns and healthcare burden among individuals with suspected pulmonary arterial hypertension (PAH), as identified through a practice guideline-based healthcare claims algorithm.

Methods:

Adults with evidence of PAH from 1 January 2004 (commercial and Medicaid) or 1 July 2006 (Medicare Advantage) through 30 June 2008 were identified. Given the lack of an ICD-9 code for PAH, an algorithm was developed requiring: (1) ≥1 claim for PAH medication (index date); (2) ≥1 claim with a pulmonary hypertension diagnosis code in the 6-month pre-index period (baseline) or within 90 days post-index; (3) a right heart catheterization or pulmonary hypertension-related inpatient stay during baseline or within 90 days post-index; and (4) continuous health plan enrollment for 6 months pre-index and ≥6 months post-index. Patients with PAH-specific medications during baseline were excluded. Treatment patterns, healthcare utilization, and costs were assessed during the period ending with the earlier of health plan disenrollment or 31 December 2008.

Results:

Among the 521 included patients, 69% were female. Most patients (94%) initiated treatment with monotherapy (most commonly sildenafil or bosentan), and 12.7% of all patients augmented their therapy by the end of the observation period. The medication possession ratio was 0.96 each for ambrisentan (SD?=?0.04), bosentan (SD?=?0.04), and sildenafil (SD?=?0.05). Overall, 72.6% of patients discontinued therapy with a mean of 149 (SD?=?170) days until discontinuation. A mean (SD) of 2.14 (1.82) all-cause office and 1.64 (1.98) outpatient visits occurred per patient per month. Mean PAH-related healthcare costs were $6617 per patient per month, comprising 71% of all-cause costs. The guideline-based algorithm may not have perfectly captured patients with PAH.

Conclusions:

Patients with suspected PAH were likely to initiate treatment with oral monotherapy, had high compliance rates, and received close ambulatory follow-up. PAH-related costs constituted the majority of all-cause healthcare costs.  相似文献

Aims: To describe healthcare resource utilization (HCRU) and costs among biologic-treated psoriasis patients in the US, overall and by disease severity.

Materials and methods: IQVIA PharMetrics Plus administrative claims data were linked with Modernizing Medicine Data Services Electronic Health Record data and used to select adult psoriasis patients between April 1, 2010 and December 31, 2014. Eligible patients were classified by disease severity (mild, moderate, severe) using a hierarchy of available clinical measures. One-year outcomes included all-cause and psoriasis-related outpatient, emergency department, inpatient, and pharmacy HCRU and costs.

Results: This study identified 2,130 biologic-treated psoriasis patients: 282 (13%) had mild, 116 (5%) moderate, and 49 (2%) severe disease; 1,683 (79%) could not be classified. The mean age was 47.6 years; 45.4% were female. Relative to mild psoriasis patients, patients with moderate or severe disease had more median all-cause outpatient encounters (28.0 [mild] vs 32.0 [moderate], 36.0 [severe]), more median psoriasis-related outpatient encounters (6.0 [mild] vs 7.5 [moderate], 8.0 [severe]), and a higher proportion of overall claims for medications that were psoriasis-related (28% [mild] vs 37% [moderate], 34% [severe]). Relative to mild psoriasis patients, patients with moderate or severe disease had higher median all-cause total costs ($37.7k [mild] vs $42.3k [moderate], $49.3k [severe]), higher median psoriasis-related total costs ($32.7k [mild] vs $34.9k [moderate], $40.5k [severe]), higher median all-cause pharmacy costs ($33.9k [mild] vs $36.5k [moderate], $36.4k [severe]), and higher median psoriasis-related pharmacy costs ($32.2k [mild] vs $33.9k [moderate], $35.6k [severe]).

Limitations: The assessment of psoriasis disease severity may not have necessarily coincided with the timing of biologic use. The definition of disease severity prevented the assessment of temporality, and may have introduced selection bias.

Conclusions: Biologic-treated patients with moderate or severe psoriasis cost the healthcare system more than patients with mild psoriasis, primarily driven by higher pharmacy costs and more outpatient encounters.  相似文献

Abstract

Objectives:

Few studies have characterized healthcare resource utilization among patients with idiopathic pulmonary fibrosis. The objective of this study is to assess healthcare resource utilization among patients with idiopathic pulmonary fibrosis as compared to members without this condition.

Methods:

Patients newly diagnosed with idiopathic pulmonary fibrosis were identified from a national administrative claims database (2006–2011) as having ≥2 claims with idiopathic fibrosing alveolitis, or ≥1 claim with idiopathic fibrosing alveolitis and ≥1 claim with post-inflammatory pulmonary fibrosis (earliest claim with idiopathic fibrosing alveolitis denoted the index date), a procedure of lung biopsy or high-resolution computed tomography within ±90 days of the index date, 12-month pre-index continuous enrollment, plus ≥2 confirmatory idiopathic fibrosing alveolitis diagnoses after the procedure. For each idiopathic pulmonary fibrosis patient, three members without the condition were matched by age/gender/region/payer type. Demographic/clinical characteristics were measured during the 1-year pre-index period. Healthcare resource utilization was assessed by quarter during 1-year pre- and post-index periods. Generalized estimating equation models controlling for patient characteristics were constructed to estimate adjusted post-index healthcare resource utilization.

Results:

In total, 1735 patients with idiopathic pulmonary fibrosis and 5205 without (mean age?=?71.5 years; 46.1% female) were included. Adjusted results revealed idiopathic pulmonary fibrosis patients were more likely to use healthcare resources than members without the condition 1-year post-index (number of hospitalizations, emergency room visits, and outpatients visits: 0.63 vs 0.31, 0.62 vs 0.48, and 5.7 vs 3.1 per person-year, respectively).

Conclusions:

Healthcare resource utilization is considerably higher among patients with idiopathic pulmonary fibrosis than members without the condition. Effective treatments for patients with idiopathic pulmonary fibrosis are needed to help reduce burden of healthcare resource use.  相似文献

Abstract

Background:

Idiopathic pulmonary fibrosis is a life-threatening condition, and few data concerning the impact on healthcare utilization and associated costs are available. The objective of this study was to describe the burden of illness (comorbidity, healthcare resource utilization, and associated costs) in patients with idiopathic pulmonary fibrosis.

Methods:

Two cohorts (patients with idiopathic pulmonary fibrosis and matched controls) were retrospectively identified from US claims databases between January 1, 2001 and September 30, 2008. Cases with idiopathic pulmonary fibrosis were defined by age of 55 years or older and either two or more claims with a code for idiopathic fibrosing alveolitis (ICD-9 516.3), or one claim with ICD 516.3 and a subsequent claim with a code for post-inflammatory pulmonary fibrosis (ICD-9 515). The prevalence and incidence of pre-selected comorbidities, healthcare resource utilization (hospital, outpatient, drugs), and direct medical costs were assessed in each cohort.

Results:

A total of 9286 patients with idiopathic pulmonary fibrosis were identified. When compared with age- and gender-matched controls, these patients were at significantly increased risk for comorbidities including pulmonary hypertension and emphysema. The all-cause hospital admission rate (0.5 per person-year) and the all-cause outpatient visit rate (28.0 per person-year) were both ~2-fold higher than in controls. Total direct costs for patients with idiopathic pulmonary fibrosis were $26,378 per person-year; the incremental costs over controls were $12,124 (2008 value).

Conclusions:

Patients with idiopathic pulmonary fibrosis experience increased comorbidity, healthcare resource utilization, and direct medical costs compared to controls.  相似文献

Aim: To estimate direct and indirect costs in patients with a diagnosis of cluster headache in the US.

Methods: Adult patients (18–64 years of age) enrolled in the Marketscan Commercial and Medicare Databases with ≥2 non-diagnostic outpatient (≥30 days apart between the two outpatient claims) or ≥1 inpatient diagnoses of cluster headache (ICD-9-CM code 339.00, 339.01, or 339.02) between January 1, 2009 and June 30, 2014, were included in the analyses. Patients had ≥6 months of continuous enrollment with medical and pharmacy coverage before and after the index date (first cluster headache diagnosis). Three outcomes were evaluated: (1) healthcare resource utilization, (2) direct healthcare costs, and (3) indirect costs associated with work days lost due to absenteeism and short-term disability. Direct costs included costs of all-cause and cluster headache-related outpatient, inpatient hospitalization, surgery, and pharmacy claims. Indirect costs were based on an average daily wage, which was estimated from the 2014?US Bureau of Labor Statistics and inflated to 2015 dollars.

Results: There were 9,328 patients with cluster headache claims included in the analysis. Cluster headache-related total direct costs (mean [standard deviation]) were $3,132 [$13,396] per patient per year (PPPY), accounting for 17.8% of the all-cause total direct cost. Cluster headache-related inpatient hospitalizations ($1,604) and pharmacy ($809) together ($2,413) contributed over 75% of the cluster headache-related direct healthcare cost. There were three sub-groups of patients with claims associated with indirect costs that included absenteeism, short-term disability, and absenteeism?+?short-term disability. Indirect costs PPPY were $4,928 [$4,860] for absenteeism, $803 [$2,621] for short-term disability, and $3,374 [$3,198] for absenteeism?+?disability.

Conclusion: Patients with cluster headache have high healthcare costs that are associated with inpatient admissions and pharmacy fulfillments, and high indirect costs associated with absenteeism and short-term disability.  相似文献

Aim: To estimate the healthcare utilization and costs in elderly lung cancer patients with and without pre-existing chronic obstructive pulmonary disease (COPD).

Methods: Using Surveillance, Epidemiology and End Results (SEER)-Medicare data, this study identified patients with lung cancer between 2006–2010, at least 66 years of age, and continuously enrolled in Medicare Parts A and B in the 12 months prior to cancer diagnosis. The diagnosis of pre-existing COPD in lung cancer patients was identified using ICD-9 codes. Healthcare utilization and costs were categorized as inpatient hospitalizations, skilled nursing facility (SNF) use, physician office visits, ER visits, and outpatient encounters for every stage of lung cancer. The adjusted analysis was performed using a generalized linear model for healthcare costs and a negative binomial model for healthcare utilization.

Results: Inpatient admissions in the COPD group increased for each stage of non-small cell lung cancer (NSCLC) compared to the non-COPD group per 100 person-months (Stage I: 14.67 vs 9.49 stays, p?<?.0001; Stage II: 14.13 vs 10.78 stays, p?<?.0001; Stage III: 28.31 vs 18.91 stays, p?<?.0001; Stage IV: 49.5 vs 31.24 stays, p?<?.0001). A similar trend was observed for outpatient visits, with an increase in utilization among the COPD group (Stage I: 1136.04 vs 796 visits, p?<?.0001; Stage II: 1325.12 vs 983.26 visits, p?<?.0001; Stage III: 2025.47 vs 1656.64 visits, p?<?.0001; Stage IV: 2825.73 vs 2422.26 visits, p?<?.0001). Total direct costs per person-month in patients with pre-existing COPD were significantly higher than the non-COPD group across all services ($54,799.16 vs $41,862.91). Outpatient visits represented the largest cost category across all services in both groups, with higher costs among the COPD group ($41,203 vs $31,140.08).

Conclusion: Healthcare utilization and costs among lung cancer patients with pre-existing COPD was ~2–3-times higher than the non-COPD group.  相似文献

Objective Hidradenitis suppurativa (HS) is often treated by surgery. The risk of recurrence after surgery is common and the consequences are substantial, but neither has been quantified using a claims database. This study aimed to estimate the burden associated with non-curative surgery in HS patients.

Methods A retrospective analysis was performed of health insurance claims data from Q1 1999 to Q2 2011 in a US claims database. The analysis included 2668 adults with ≥1 diagnosis of HS and ≥1 claim for skin surgery within 6 months after diagnosis. Healthcare resource utilization and medical costs were compared using multivariate regressions.

Results Overall, 46% of HS patients had ≥1 indicator of non-curative surgery. The incidences of inpatient, emergency department, and outpatient visits were 88%, 40%, and 30% higher, respectively, for patients with non-curative surgery vs patients without indicator of non-curative surgery (all p?<?0.001). Average medical costs were $11,858 and $6427 for patients with and without indicators of non-curative surgery, respectively. The difference of $4185 (p?<?0.001) was mainly driven by inpatient costs (difference = $2685; p?<?0.001).

Limitations Indicators of non-curative HS surgery were defined based on an empirical algorithm.

Conclusions Non-curative HS surgery occurred in almost half of all cases and represents a significant burden on patients and payers in terms of resource utilization and costs.  相似文献
