What happens after a single surgical intervention for hidradenitis suppurativa? A retrospective claims-based analysis

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.     

Patient- and clinician-reported satisfaction with pharmacological stress agents for single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI)

Abstract

Objective:

The objective of this study was to compare clinician and patient measures of satisfaction with two pharmacological stress agents (PSA), regadenoson and dipyridamole, used in Single Photon Emission Computed Tomography (SPECT) Myocardial Perfusion Imaging (MPI).

Methods:

This observational study included patients who had undergone SPECT MPI with regadenoson or dipyridamole, as well as the clinician/clinical technologist who performed the test. Mean scores for individual item and domain scores of the main outcome measures were computed as well as the effect sizes (ES) of the mean difference in scores between treatment groups. Statistical significance of the mean item and domain score differences were assessed via Mann-Whitney tests.

Main outcomes measures:

Two self-report questionnaires which had beeb previously developed and validated: Patient Satisfaction/Preference Questionnaire (PSPQ) and Clinician Satisfaction/Preference Questionnaire (CSPQ).

Results:

A total of 87 patients (68 received regadenoson, 19 received dipyridamole) and nine clinicians/clinical technologists took part in the study. Patients had a mean age of 66.8?±?12.2 years, and 56.3% were male. Compared to dipyridamole, use of regadenoson was associated with greater clinician satisfaction on all items and domains of the CSPQ (p?<?0.001 for all comparisons). Among patients, regadenoson was associated with less bother and greater satisfaction than dipyridamole for all items on the PSPQ. These patients reported less stinging at the injection site (ES?=??0.66) and less nervousness during injection (ES?=??0.60). The PSPQ found that regadenoson patients were more satisfied with their PSA than dipyridamole patients in all areas.

Limitations:

This study utilized a relatively small sample size of dipyridamole patients and lacked an adenosine group. A broader sampling of professionals would also help demonstrate generalizability.

Conclusion:

Both patients and clinicians reported higher satisfaction with regadenoson compared to dipyridamole for SPECT-MPI. Clinicians were particularly satisfied with the preparation and administration aspects of the drug, while patients rated it highly on convenience and reduced incidence of side-effects.     

Medical resource utilisation and healthcare costs in patients with chronic hepatitis C viral infection and thrombocytopenia

Abstract

Background:

Thrombocytopenia is a significant risk for patients with chronic HCV infection and a common side-effect of treatment with pegylated (PEG) interferon (IFN). Thrombocytopenia predisposes patients to bleeding and requirements for platelet transfusions, and may thus place an increased burden on patients and on medical resource utilisation.

Scope:

In a retrospective analysis of an integrated, longitudinal database of medical and pharmacy claims and laboratory results in a US commercial health (insurance) plan, patients with chronic hepatitis C viral (HCV) infection were identified by reviewing ICD-9-CM HCV-, chronic liver disease-, and cirrhosis-related diagnoses. Medical resource utilisation and laboratory results were evaluated during the year following the HCV diagnosis index date as well as during the baseline year prior to that index date. Medical resource utilisation was determined by comparing outpatient visits, emergency department (ER) visits, and inpatient hospital stays for HCV patients with or without thrombocytopenia.

Findings:

HCV patients diagnosed with thrombocytopenia had a greater incidence of bleeding events (27.3 vs. 9.9%), platelet transfusions (8.5 vs. <1%), liver disease-related ambulatory visits (10.4 vs. 4.4; odds ratio [OR]?=?2.3; p?<?0.001), ER visits (OR?=?8.6; p?<?0.01), and inpatient hospital stays (OR?=?17.7; p?<?0.01) during the study period compared with HCV patients without a thrombocytopenia diagnosis. HCV patients with thrombocytopenia had significantly higher overall healthcare costs ($37,924 vs. $12,174; p?<?0.001) and liver disease-related costs ($14,569 vs. $4107; p?<?0.001) than patients without thrombocytopenia.

Limitations:

Administrative claims data are subject to coding errors; additionally, the patient population may not be completely representative of the general chronic HCV population.

Conclusions:

Diagnosis of thrombocytopenia in patients with HCV is associated with increased incidence of certain comorbidities, complications, and medical interventions, and significantly increased medical resource utilisation.     

Clinical comorbidities,treatment patterns,and direct medical costs of patients with osteoarthritis in usual care: a retrospective claims database analysis

Abstract

Objective:

Comorbidities and resource utilization among patients with osteoarthritis (OA) in clinical practice have been infrequently characterized. The purpose of this study was to examine comorbidities, pain-related pharmacotherapy, and direct medical costs of patients with OA in clinical practice.

Method:

This retrospective cohort analysis used medical and pharmacy claims data from the LifeLink? Database. OA patients (ICD-9-CM codes 715.XX) were matched (age, gender, and region) with individuals without OA. Comorbidities, pain-related pharmacotherapy, and direct medical costs (pharmacy, outpatient, inpatient, total) were examined for the calendar year 2008.

Results:

The sample consisted of 112,951 OA patients and 112,951 controls (mean age: 56.9 [SD?=?9.5] years; 62% female). Relative to controls, OA patients were significantly more likely (p?<?0.0001) to have comorbidities, including musculoskeletal (84.3 vs. 37.1%) and neuropathic pain (22.0 vs. 6.1%) conditions, depression (12.4 vs. 6.4%), anxiety (6.6 vs. 3.5%), and sleep disorders (11.9 vs. 4.2%). OA patients were significantly more likely (p?<?0.0001) to receive pain-related medications, including opioids (40.7 vs. 17.1%), NSAIDs (37.1 vs. 11.5%), tramadol (9.8 vs. 1.8%), and adjunctive medications for treating depression, anxiety, and insomnia. Mean [SD] total direct medical costs were more than two times higher among OA patients ($12,905 [$21,884] vs. $5099 [$13,855]; p?<?0.001) and median costs were more than three times higher ($6188 vs. $1879; p?<?0.0001). Study limitations include potential errors in coding and recording; overestimation of the comorbidity burden; inability to link condition of interest, OA, with prescribed medications; and possible underestimation of the true costs of OA, because indirect costs were not considered and the direct costs were from a third party payer (commercial insurance) perspective.

Conclusion:

The patient burden of OA was characterized by a high prevalence of comorbidities. The payer burden was also substantial, with significantly greater use of pain-related and adjunctive medications, and higher direct medical costs.     

Resource utilization and healthcare costs for acute coronary syndrome patients with and without diabetes mellitus

Abstract

Objective:

This study compared differences in healthcare costs and resource utilization for acute coronary syndrome (ACS) patients with and without diabetes mellitus (DM).

Methods:

A retrospective cohort study of a large, US employer-based claims database identified adults hospitalized for ACS between 01/01/2005 and 12/31/2006 and categorized them based on DM status. Resource utilization and costs during the index hospitalization and in the 12-month follow-up period were compared for ACS patients with and without DM using the propensity score stratification bootstrapping method, adjusting for differences in demographic and clinical characteristics.

Results:

Of 12,502 patients who met selection criteria, 3,040 (24%) had a history of DM and 9,462 (76%) did not. Patients with DM were older, female, and had higher rates of previous cardiovascular and renal diseases. After the propensity score stratification, patients with DM incurred higher index hospitalization costs ($32,577 vs. $29,150, p?<?0.01) as well as higher total follow-up healthcare costs ($35,400 vs. $24,080, p?<?0.01), including higher inpatient ($17,278 vs. $11,247, p?<?0.01), outpatient ($12,357 vs. $8,853, p?<?0.01), and pharmacy costs ($5,765 vs. $3,980, p?<?0.01).

Limitations:

General limitations exist with any retrospective claims database analysis including potential diagnostic or procedural coding inaccuracies. Additionally, the patient population was representative of a working-age population with employer-sponsored health insurance and results may not be generalizable to other patient populations.

Conclusions:

DM is significantly associated with increased healthcare resource utilization and costs for ACS patients.     

The real-world economic impact of home-based video electroencephalography: the payer perspective

Abstract

Aims: Electroencephalography (EEG) is an established method to evaluate and manage epilepsy; video EEG (VEEG) has significantly improved its diagnostic value. This study compared healthcare costs and diagnostic-related outcomes associated with outpatient vs inpatient VEEG among patients with epilepsy in the US.

Materials and methods: This study used Truven MarketScan Commercial and Medicare Supplemental claims databases. Patients with a VEEG between July 1, 2013 and December 31, 2016 were identified. Index event was the first VEEG claim, which was used to determine inpatient and outpatient cohorts. Continuous health plan enrollment 6?months pre- and 12?months post-index VEEG was required. Primary outcomes were costs during the index event and 12?months post index. A generalized linear model with gamma distribution and a log link was used to estimate adjusted index and post-index costs.

Results: Controlling for baseline differences, epilepsy-related cost of index VEEG was significantly lower for the outpatient ($4,098) vs the inpatient cohort ($13,821; p?<?0.0001). The cost differences observed at index were maintained in the post-index period. The 12-month post-index epilepsy-related costs were lower in the outpatient cohort ($6,114 vs $12,733, p?<?0.0001). Time from physician referral to index VEEG was significantly shorter in the outpatient cohort (30.6 vs 42.5?days). Patients in the inpatient cohort were also more likely to undergo an additional subsequent follow-up inpatient VEEG (p?<?0.0001).

Limitations: Administrative claims data have limitations, including lack of data on clinical presentation, disease severity, and comprehensive health plan information. Generalizability may be limited to a US insured population of patients who met study criteria.

Conclusions: Index VEEG was less costly in an outpatient vs inpatient cohort, and costs were lower during the follow-up period of 12?months, suggesting that outpatient VEEG can be provided to appropriate patients as a less costly option. There were fewer follow-up tests in the outpatient cohort with similar pre- and post-index diagnoses.     

Indirect costs associated with metastatic breast cancer

Abstract

Objective:

To compare the indirect costs of productivity loss between metastatic breast cancer (MBC) and early stage breast cancer (EBC) patients, as well as their respective family members.

Methods:

The MarketScan® Health and Productivity Management database (2005–2009) was used. Adult BC patients eligible for employee benefits of sick leave and/or short-term disability were identified with ICD-9 codes. Difference in sick leave and short-term disability days was calculated between MBC patients and their propensity score matched EBC cohort and general population (controls) during a 12-month follow-up period. Generalized linear models were used to examine the impact of MBC on indirect costs to patients and their families.

Results:

A total of 139 MBC, 432 EBC, and 820 controls were eligible for sick leave and 432 MBC, 1552 EBC, and 4682 controls were eligible for short-term disability (not mutually exclusive). After matching, no statistical difference was found in sick leave days and the associated costs between MBC and EBC cohorts. However, MBC patients had significantly higher short-term disability costs than EBC patients and controls (MBC: $6166?±?$9194 vs EBC: $3690?±?$6673 vs Controls: $558?±?$2487, both p?<?0.001). MBC patients had more sick leave cost than controls ($2383?±?$5539 vs $1282?±?$2083, p?<?0.05). Controlling for covariates, MBC patients incurred 47% more short-term disability costs vs EBC patients (p?=?0.009). Older patients (p?=?0.002), non-HMO payers (p?<?0.05), or patients not receiving chemotherapy during follow-up (p?<?0.001) were associated with lower short-term disability costs. MBC patients’ families incurred 39.7% (p?=?0.06) higher indirect costs compared to EBC patients’ families after controlling for key covariates.

Conclusion:

Productivity loss and associated costs in MBC patients are substantially higher than EBC patients or the general population. These findings underscore the economic burden of MBC from a US societal perspective. Various treatment regimens should be evaluated to identify opportunities to reduce the disease burden from the societal perspective.     

Medical resource use and costs associated with chylomicronemia

Abstract

Background:

The prevalence of severe hypertriglyceridemia (TG?>?1000?mg/dl) is estimated at 150–400 per 100,000 individuals in North America. Severe hypertriglyceridemia in the fasting state is associated with increased acute pancreatitis risk and is a sign of chylomicronemia which reflects the accumulation in the bloodstream of chylomicrons, the large lipoprotein particles produced in the gut after a meal.

Objective:

To assess medical resource use and costs associated with chylomicronemia.

Methods:

Patients with chylomicronemia of different causes (≥2 diagnoses with ICD-9 code 272.3) were identified from a large US claims database (years 2000 to 2009) and matched 1:1 to controls free of chylomicronemia based on age, gender, demographics, comorbidities, and use of lipid lowering drugs. During a 1-year study period, medical resource use and costs associated with chylomicronemia or acute pancreatitis were compared between matched cases and controls.

Results:

Among 6472 matched pairs, annual per-patient medical costs, calculated independently of the occurrence of acute pancreatitis, were significantly greater by $808 for chylomicronemia cases vs controls ($8029 vs $7220, p?<?0.01), half of which was attributable to chylomicronemia-related services (p?<?0.01). Chylomicronemia cases with a history of acute pancreatitis (n?=?46) had greater rates of inpatient visits (p?<?0.05) and greater average costs for subsequent acute pancreatitis or abdominal pain (p?<?0.01) as well as greater total medical costs ($33,587 vs $4402, p?<?0.01) vs matched controls. The average episode of acute pancreatitis (n?=?104 episodes) generated medical costs of $31,820, almost entirely due to inpatient stays.

Limitations:

Triglyceride levels were not available to characterize disease severity.

Conclusions:

Patients with chylomicronemia, and especially those with a history of acute pancreatitis, incurred significantly greater total medical costs compared with individuals without chylomicronemia but with an otherwise comparable health profile.     

Evaluating medical resource utilization and costs associated with thrombocytopenia in chronic liver disease patients

Abstract

Objective:

Thrombocytopenia (TCP), defined as platelet counts <150,000/µL, is a common complication of severe chronic liver disease (CLD). This retrospective study estimated the prevalence of thrombocytopenia in a large population of CLD patients and compared medical resource utilization and medical care costs by TCP status.

Methods:

A retrospective analysis was conducted on a longitudinal administrative claims database from a large US commercial health plan. Patients assigned CLD diagnosis codes from January 1, 2000–December 31, 2003 were identified; annual ambulatory visits, ER visits, inpatient stays, and general and CLD-related medical care costs for patients with vs without TCP (identified using diagnosis codes and platelet count data if available) were compared.

Results:

Of 56,445 patients with an ICD-9-CM diagnosis for CLD, 1289 (2.3%) had a diagnosis for TCP. CLD patients with vs without a TCP diagnosis had >2.5-times the annual number of liver disease-related ambulatory visits (3.6 vs 1.4; odds ratio [OR]?=?2.6, p?<?0.01); were 13-times more likely to have a liver-related inpatient stay (OR?=?13.0, p?<?0.01); were nearly 4-times more likely to have a liver-related ER visit (OR?=?3.9, p?<?0.01); had 3.5-fold greater mean annual overall medical care costs ($43,560 vs $12,270, p?<?0.01); and had 7-fold greater annual liver disease-related medical care costs ($9940 vs $1420, p?<?0.01). Similar results were seen for patients with platelet count data indicating TCP.

Limitations:

CLD and TCP are not always diagnosed, nor is diagnosis uniform or standardized; administrative claims data are subject to coding errors, and individuals covered are not necessarily representative of the general US population. The number of CLD patients in this study with TCP (n?=?1289) is small relative to that expected in the general US population.

Conclusions:

In this analysis, CLD patients with TCP used significantly more medical resources and incurred significantly higher medical care costs than those without TCP.     

Medical costs and healthcare resource use in patients with lupus nephritis and neuropsychiatric lupus in an insured population

Abstract

Objective:

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that can affect multiple organ systems, including the kidneys (lupus nephritis) and the central nervous system (neuropsychiatric lupus, or NPSLE). The healthcare costs and resource utilization associated with treating lupus nephritis and NPSLE in a large US managed care plan were studied.

Methods:

SLE subjects ≥18 years of age and with claims-based evidence of nephritis or neuropsychiatric conditions were identified from a health plan database. An index date was set as a randomly drawn date from all qualifying claims during 2003–2008 for study subjects. Subjects were matched on the basis of demographic and clinical characteristics to unaffected controls. Costs and resource use were determined during a fixed 12-month post-index period.

Results:

Nine hundred and seven lupus nephritis subjects were matched to controls, and 1062 subjects with NPSLE were matched to controls. Mean overall post-index healthcare costs were significantly higher among subjects with lupus nephritis in comparison to matched controls ($33,472 vs $5347, p?<?0.001). Similarly, mean overall post-index healthcare costs were significantly higher among subjects with NPSLE compared to controls ($30,341 vs $4646, p?<?0.001). Subjects with lupus nephritis or NPSLE had higher mean post-index numbers of ambulatory visits, specialist visits, emergency department visits and inpatient hospital stays, compared to controls (all p?<?0.001).

Limitations:

Additional research, such as medical chart review, could provide validation for the claims-based identification of lupus nephritis and NPSLE subjects. Also, indirect costs were not evaluated in this study.

Conclusion:

Subjects with lupus nephritis or NPSLE have high costs and resource use, compared to unaffected controls.     

Treatment patterns and resource utilization and costs among patients with pulmonary arterial hypertension in the United States

Abstract

Objective:

To explore treatment patterns and resource utilization and cost for subjects with pulmonary arterial hypertension (PAH).

Research design:

Retrospective claims database analysis of 706 patients with PAH enrolled in a large, geographically diverse US managed-care organization.

Results:

In the final sample of PAH patients treated with bosentan (n?=?251) or sildenafil (n?=?455), average age was 57 years, 86% of patients were commercially insured, and 52% of patients were male. Gender distribution varied significantly across subgroups, with a lower proportion of males in the bosentan (30%) subgroup compared with the sildenafil group (64%) (p?<?0.001). Average baseline Charlson comorbidity score was 2.4. Average numbers of fills per month were 0.8 and 0.4 for bosentan and sildenafil patients, respectively (p?<?0.001). Over 80% of patients received only one PAH treatment in the first 90 days following the index date, with 28% of bosentan and 13% of sildenafil patients receiving combination therapy (p?<?0.001). Over one-third of bosentan patients and one-quarter of sildenafil patients experienced a dose increase in the follow-up period (p?=?0.009). Sixteen percent of sildenafil patients experienced a dose decrease in the follow-up period, while a smaller proportion of patients receiving bosentan (4%) experienced a dose decrease (p?<?0.001). On average, number of PAH-related per subject per month (PSPM) inpatient stays and emergency department visits and PSPM length of inpatient stays were statistically similar between the subgroups. PAH-related PSPM healthcare costs were high for both subgroups, with average monthly costs of $5,332 and $3,632 among bosentan and sildenafil patients, respectively (p?=?0.003). Differences in total costs were driven mainly by differences in pharmacy expenditures.

Conclusions:

Of the oral agents approved for treating PAH at the time of this study, sildenafil was most commonly prescribed as index therapy and was also associated with the lowest costs, largely due to significantly lower pharmacy costs. This study is characterized by limitations inherent to claims database analyses, such as the potential for coding errors and lack of information on whether a drug was taken as prescribed. Furthermore, PAH severity (WHO functional class) was not assessed.     

Economic outcomes of exenatide vs liraglutide in type 2 diabetes patients in the United States: results from a retrospective claims database analysis

Abstract

Objective:

The safety and efficacy of the GLP-1 receptor agonists exenatide BID (exenatide) and liraglutide for treating type 2 diabetes mellitus (T2DM) have been established in clinical trials. Effective treatments may lower overall treatment costs. This study examined cost offsets and medication adherence for exenatide vs liraglutide in a large, managed care population in the US.

Methods:

This was a retrospective cohort analysis comprising adult patients with T2DM who initiated exenatide or liraglutide between 1/1/2010 and 6/30/2010 and had 6 months pre-index and post-index continuous eligibility. Patients were propensity score-matched to controls for baseline differences. Medication adherence was measured by proportion of days covered (PDC). Paired t-test and McNemar’s test were used to compare outcomes.

Results:

Matched exenatide and liraglutide cohorts (n?=?1347 pairs) had similar average total 6-month follow-up costs ($6688 vs $7346). However, exenatide patients had significantly lower mean pharmacy costs ($2925 vs $3272, p?<?0.001). Among liraglutide patients, patients receiving the 1.8?mg dose had significantly higher average total costs compared to those receiving the 1.2?mg dose ($8031 vs $6536, p?=?0.026), with higher mean pharmacy costs in the 1.8?mg cohort ($3935 vs $3146, p?<?0.001). There were no significant differences in inpatient or outpatient costs or medication adherence between groups (mean PDC: exenatide 56% vs liraglutide 57%, p?=?0.088).

Limitations:

The study assumed that all information needed for case classification and matching of cohorts was present and not differential across cohorts. The study did not control for covariates that were unavailable, such as HbA1c and duration of diabetes.

Conclusions:

Patients initiating exenatide vs liraglutide for T2DM had similar medication adherence and total healthcare costs; however, exenatide patients had significantly lower total pharmacy costs. Patients prescribed 1.8?mg liraglutide had significantly higher costs compared to those on 1.2?mg.     

One-year follow-up healthcare costs of patients hospitalized for transient ischemic attack or ischemic stroke and discharged with aspirin plus extended-release dipyridamole or clopidogrel

Abstract

Objective:

To examine healthcare costs among patients hospitalized for transient ischemic attack or ischemic stroke (TIA/stroke) and prescribed aspirin plus extended-release dipyridamole (ASA-ERDP) or clopidogrel (CLOPID) within 30 days post-discharge using a retrospective claims database from a large US managed care organization.

Methods:

Adult patients with ≥1 hospitalizations for TIA/stroke between January 2007–July 2009 and ≥1 claims for an oral anti-platelet (OAP) were observed for 1 year before and after the first TIA/stroke hospitalization or until death, whichever came first. Cohorts were defined by the first claim for ASA-ERDP or CLOPID within 30 days post-discharge. A generalized linear model, adjusting for demographics, baseline comorbidities and costs, compared total follow-up costs (medical?+?pharmacy) between ASA-ERDP and CLOPID patients.

Results:

Of 6377 patients (2085 ASA-ERDP; 4292 CLOPID) who met the selection criteria, mean (SD) age was 69 (13) years and 50% were male. Unadjusted mean total follow-up costs were lower for ASA-ERDP than CLOPID ($26,201 vs $30,349; p?=?0.002), of which average unadjusted medical and pharmacy costs were $22,094 vs $26,062 (p?=?0.003) and $4107 vs $4288 (p?=?0.119), respectively. Multivariate modeling indicated that the following were associated with higher total costs (all p?<?0.05): higher baseline Quan-Charlson comorbidity score, history of atrial fibrillation and myocardial infarction, index stroke hospitalization, death post-discharge, and index CLOPID use. Adjusted mean total follow-up costs for CLOPID were 9% higher than ASA-ERDP (cost ratio: 1.09; p?=?0.038).

Conclusion:

In this study, compared to CLOPID patients, ASA-ERDP patients were observed to have lower total costs 1 year post-discharge TIA/stroke hospitalization, driven primarily by lower medical costs. Further research into the real-world impact of OAP therapies on clinical and economic outcomes of patients with stroke/TIA is warranted. The findings of this study should be considered within the limitations of an administrative claims analysis, as claims data are collected for the purpose of payment.     

Short-term disability in solid tumor patients with bone metastases and skeletal-related events

Abstract

Objective:

The skeleton is a common site of metastasis in patients with solid tumors. These patients often experience pain and reduced quality-of-life. This analysis evaluated the time and costs associated with short-term disability use among solid tumor patients with bone metastases (BM) and skeletal-related events (SREs).

Methods:

Data from patients 18–64 years old with solid tumors and BM, eligible for short-term disability benefits between January 1, 2002 and December 31, 2010, were extracted from MarketScan Research Databases. Short-term disability hours and costs associated with BM and SREs were evaluated.

Results:

Overall, 1098 patients met the criteria. For all patients with BM, the monthly mean short-term disability hours were 17.7?h pre-BM diagnosis and increased to 60.2?h post-BM diagnosis (p?<?0.001). The corresponding mean monthly short-term disability costs were $277 and $963 in the pre- and post-BM diagnosis periods, respectively (p?<?0.001). Monthly mean short-term disability hours were higher for the cohort of patients with SREs (21.2?h pre-SRE diagnosis and 67.4?h post-SRE diagnosis) than for those without an SRE (8.6?h pre-SRE diagnosis and 14.4?h post-SRE diagnosis) (p?<?0.001). Similarly, the corresponding monthly mean short-term disability costs were higher for patients with SREs ($625 and $1259 pre- and post-SRE diagnosis, respectively) than for patients without an SRE ($452 and $612 pre- and post-SRE diagnosis, respectively) (p?<?0.001). Results of a multivariate analysis indicated that SREs were associated with an additional 39.4 short-term disability hours and $613 in short-term disability costs per month (p?<?0.001).

>Conclusion:

Short-term disability hours and costs increased significantly when patients with solid tumors developed BM and SRE.
