Economic and Health Care Resource Use Burden of Systemic Sclerosis.

OBJECTIVE: To describe the health care resource use (HCRU) and costs of patients with systemic sclerosis (SSc) prior to and after diagnosis. METHODS: This retrospective study used a claims data set (Merative MarketScan; 2015-2019). Eligible patients with SSc were identified by diagnosis codes and required at least 24 months of enrollment without an SSc diagnosis before their first SSc claim and at least 12 months of enrollment thereafter. Total HCRU and costs were reported for three intervals: 2 years and 1 year before and 1 year after index diagnosis. A general population cohort without SSc was matched 1:1 to the SSC cohort on age and sex for comparison. RESULTS: Eligibility criteria identified 902 patients with SSc (mean age: 54 years old; 85% female). Mean per-member per year costs increased each year from $22,383 to $29,708 to $47,095, 2 years before, 1 year before, and 1 year after index diagnosis versus $10,232 to $9656 to $9714 in the general population cohort. Outpatient settings represented the largest proportion of cost 1 year after SSc diagnosis ($16,392), followed by prescription drugs ($10,692), physician office ($10,523), and inpatient ($9448) settings. CONCLUSION: Patients with SSC accrued greater costs and required more services than a general population cohort. These elevated expenditures and HCRU were observed at least 2 years before an SSc diagnosis and increased over time, reflecting both the progressive, multisystem nature of SSc and potential challenges in diagnosis. These findings suggest that SSc poses a substantial burden on the US health care system and highlights the need for early diagnosis and effective therapies.

Association Between Treatment Progression, Disease Refractoriness, and Burden of Illness Among Hospitalized Patients With Status Epilepticus.

Importance: Status epilepticus (SE) is associated with poor clinical outcomes and high cost. Increased levels of refractory SE require treatment with additional medications and carry increased morbidity and mortality, but the associations between SE refractoriness, clinical outcomes, and cost remain poorly characterized. Objective: To examine differences in clinical outcomes and costs associated with hospitalization for SE of varying refractoriness. Design, Setting, and Participants: A cross-sectional study of 43 988 US hospitalizations from January 1, 2016 to December 31, 2018, was conducted, including patients with primary or secondary International Statistical Classification of Diseases, Tenth Revision, diagnosis specifying "with status epilepticus." Exposure: Patients were categorized by administration of antiseizure drugs given during hospitalization. Low refractoriness denoted treatment with none or 1 intravenous antiseizure drug. Moderate refractoriness denoted treatment with more than 1 intravenous antiseizure drug. High refractoriness denoted treatment with 1 or more intravenous antiseizure drug, more than 1 intravenous anesthetic, and intensive care unit admission. Main Outcomes and Measures: Outcomes included discharge disposition, hospital length of stay, intensive care unit length of stay, hospital-acquired conditions, and cost (total and per diem). Results: Among 43 988 hospitalizations for SE, 22 851 patients (51.9%) were male; mean age was 49.9 years (95% CI, 49.7-50.1 years). There were 14 694 admissions (33.4%) for low refractory, 10 140 (23.1%) for moderate refractory, and 19 154 (43.5%) for highly refractory SE. In-hospital mortality was 11.2% overall, with the highest rates among patients with highly (18.9%) compared with moderate (6.3%) and low (4.6%) refractory SE (P < .001 for all comparisons). Median hospital length of stay was 5 days (interquartile range [IQR], 2-10 days) with greater length of stay in highly (8 days; IQR, 4-15 days) compared with moderate (4 days; IQR, 2-8 days) and low (3 days; IQR, 2-5 days) refractory SE (P < .001 for all comparisons). Patients with highly refractory SE also had greater hospital costs, with median costs of $25 105 (mean [SD], $41 858 [$59 063]) in the high, $10 592 (mean [SD], $18 328 [$30 776]) in the moderate, and $6812 (mean [SD], $11 532 [$17 228]) in the low refractory cohorts (P < .001 for all comparisons). Conclusions and Relevance: Status epilepticus apparently continues to be associated with a large burden on patients and the US health system, with high mortality and costs that increase with disease refractoriness. Interventions that prevent SE from progressing to a more refractory state may have the potential to improve outcomes and lower costs associated with this neurologic condition.

New-Onset Gout as an Independent Risk Factor for Returning to Dialysis After Kidney Transplantation.

BACKGROUND: The causal relationship between gout and renal transplant outcomes is difficult to assess due to multiple interacting covariates. This study sought to estimate the independent effect of new-onset gout on renal transplant outcomes using a methodology that accounted for these interactions. METHODS: This study analyzed data on patients in the US Renal Data System (USRDS) who received a primary kidney transplant between 2008 and 2015. The exposure was new-onset gout, and the primary endpoint was returning to dialysis >12 months postindex date (transplant date). A marginal structural model (MSM) was fitted to determine the relative risk of new-onset gout on return to dialysis. RESULTS: 18 525 kidney transplant recipients in the USRDS met study eligibility. One thousand three hundred ninety-nine (7.6%) patients developed new-onset gout, and 1420 (7.7%) returned to dialysis >12 months postindex. Adjusting for baseline and time-varying confounders via the MSM showed new-onset gout was associated with a 51% increased risk of return to (RR, 1.51; 95% CI, 1.03-2.20). CONCLUSIONS: This finding suggests that new onset gout after kidney transplantation could be a harbinger for poor renal outcomes, and to our knowledge is the first study of kidney transplant outcomes using a technique that accounted for the dynamic relationship between renal dysfunction and gout.

A Retrospective Cohort Study of the Effect of Gout on Mortality Among Patients with a History of Kidney Transplantation.

BACKGROUND Kidney transplantation is associated with increased prevalence of gout. However, evidence of the effect of gout on long-term kidney transplantation outcomes is mixed. This study examined mortality risk among patients with a history of kidney transplantation with vs. without gout. MATERIAL AND METHODS A retrospective study was conducted using Medicare Fee-for-Service administrative claims of patients with a history of kidney transplantation. Cox proportional hazards models determined the effect of gout on all-cause mortality, controlling for confounders, including comorbid mortality risk, via the Charlson Comorbidity Index. Because the relationships between gout and components of the Charlson Comorbidity Index are also debated, 3 different model assumptions were used: 1) gout shares a common cause with these comorbidities, 2) gout is upstream of these comorbidities, 3) the effect of gout on mortality is modified by these comorbidities. RESULTS Gout increased the risk of all-cause mortality in the unadjusted model (hazard ratio: 1.44, 95% CI 1.27-1.63) and after adjustment for demographics and transplant vintage (hazard ratio: 1.16, 95% CI 1.02-1.32). Gout was not a significant risk after adjustment for baseline Charlson Comorbidity Index (hazard ratio: 1.03, 95% CI 0.90-1.17). Gout was associated with greater mortality among patients without baseline comorbidities (Charlson Comorbidity Index=0; hazard ratio: 3.48, 95% CI 1.27-9.57) in the stratified model. CONCLUSIONS Among patients with a history of kidney transplantation, gout did not have an independent effect on all-cause mortality. However, gout was a predictor of mortality among patients with no comorbidities, suggesting that gout is an early warning sign of poor health in kidney transplantation patients.

Immunosuppressant Use and Gout in the Prevalent Solid Organ Transplantation Population.

INTRODUCTION: Gout is a common comorbidity among solid organ transplantation patients and is usually attributed to the use of cyclosporine. This study aims to evaluate the prevalence of gout among solid organ transplantation patients to determine the prevalence in the tacrolimus era. RESEARCH QUESTIONS: To what degree is cyclosporine still used among prevalent solid organ transplantation patients? How prevalent is gout in the solid organ transplantation population not being treated by cyclosporine? METHODS: Immunosuppressant regimens and gout prevalence among prevalent solid organ transplantation patients were assessed using retrospective claims data for a representative sample of commercially insured patients. For comparison to the prevalent solid organ transplantation population, immunosuppressant use at time of transplantation was compiled from published reports. RESULTS: Between 2012 and 2016, the use of cyclosporine declined while use of tacrolimus increased, with greater cyclosporine use among prevalent versus incident solid organ transplantation patients. The prevalence of gout was 18.3%, 9.3%, and 9.1% for solid organ transplantation patients on cyclosporine, tacrolimus, and neither, respectively. Among all solid organ transplantation patients with gout, 66.6% and 21.5% were on tacrolimus versus cyclosporine. The prevalence of gout among noncyclosporine solid organ transplantation patients was significantly higher than in the general population without solid organ transplantation. DISCUSSION: Despite declining cyclosporine use, gout prevalence remains high, with the majority of patients with gout receiving tacrolimus rather than cyclosporine. In summary, gout remains a frequent comorbidity of solid organ transplantation.

Costs Associated with the Treatment of Low Back Disorders: A Comparison of Surgeons and Physiatrists.

BACKGROUND: Spine care is costly and subject to wide variability. Defining costs and patterns of care for different specialties is critical to improving value. OBJECTIVE: Determine costs, utilization, and differences therein for nonoperative and operative specialists in treating low back disorders. We hypothesized costs associated with nonoperative specialists would be lower. DESIGN: Retrospective cohort. SETTING: Medicare Limited Data Set (5% sample), 2011 to 2014. PARTICIPANTS: A total of 170 011 patients saw a primary care provider for a low back disorder between 1 July 2011, and 1 January 2013. Excluding those seen for a low back disorder in the preceding 6 months, final cohorts totaled 11 829 patients subsequently evaluated by a physiatrist (specialist in physical medicine and rehabilitation; 3183 patients) or surgeon (orthopedic or neurosurgeon; 8646 patients) within the following 6 months. MAIN OUTCOME MEASURES: Total Medicare expenditures, spine-specific costs, spine surgical rates over 24 months. RESULTS: Cohorts had comparable demographics, initial diagnoses, and baseline mean per-member per-month (PMPM) total spending. Mean 2-year spine-specific spending was $3978 for the physiatrist cohort and $7387 for the surgeon cohort. Comparatively, the physiatrist cohort had lower total mean 2-year spine-specific spending (-$3409; 95% confidence interval [CI] -$3824 to -$2994), mean PMPM total spending (-$122/mo; CI -$184 to -$60), and surgical rate (7.8% vs. 18.9%, risk ratio [RR] = 0.41; CI 0.36-0.47). Surgery predominantly drove cost differential. Mean PMPM total spending for both cohorts remained elevated at 24 months compared to baseline mean spending (physiatrist: +$293; CI $447 to $138; surgeon: +$325; CI $425 to $225). CONCLUSIONS: Following a new episode of a low back disorder, substantial costs were seen for those subsequently evaluated by a physiatrist or surgeon. Costs were considerably lower for those first seen by a physiatrist. Patients in both cohorts displayed long-term increases in health care costs. Our data suggest that early engagement in nonoperative care, when appropriate, may improve value.

Prevalence of Gout in the Surviving United States Solid Organ Transplantation Population.

PURPOSE: Although incidence and survival are frequent topics within the solid organ transplantation (SOT) literature, the size of the surviving SOT population is not well known. Existing studies of gout in patients with SOT have focused on the incident SOT population. This analysis was performed to characterize the prevalent SOT population and the prevalence of gout within it. METHODS: This study includes the 2017 United States (US) population size of recipients of kidney, heart, liver, and lung transplants that was estimated by combining primary transplant recipient cohort sizes (1988-2017) with previously published survival rates for each annual cohort's time since transplantation (0-29 years). Gout among prevalent patients with SOT was assessed using Medicare and commercial claims. RESULTS: A total of 637,231 US patients received a primary kidney (393,953), liver (142,186), heart (66,637), or lung (34,455) transplant between 1988 and 2017. An estimated 356,000 (55.8%) recipients were alive in 2017 (233,000 kidney; 78,700 liver; 29,300 heart; 14,700 lung). Gout was identified in 11% of prevalent patients with SOT in 2016. Higher rates of gout were seen in recipients of kidney (13.1%) and heart (12.7%) compared to recipients of liver (6.7%) and lung (5.6%) (P < .0001 in both datasets). Active diagnosed gout prevalence in the US population without a SOT history was 1.1% in 2016. CONCLUSIONS: Hundreds of thousands of US patients are living with a transplanted organ today and these numbers are likely to increase. In patients with SOT, gout is a frequent comorbidity of which physicians should be aware. This study suggests a markedly higher rate of gout among transplant recipients compared to the general US population.

Gout Severity in Recipients of Kidney Transplant.

PURPOSE: This retrospective analysis of medical chart data was performed to compare severity and treatment of gout in patients with or without a history of kidney transplantation (KT). METHODS: Via an online survey, a panel of board-certified US nephrologists (N = 104) provided the following deidentified chart data for their 3 most recent patients with gout: age, sex, serum uric acid, numbers of swollen or tender joints, visible tophi, gout flare events (prior 12 months), gout drug treatment history, and KT history. The presence of "severe, uncontrolled gout" was defined as: serum uric acid ≥ 7.0 mg/dL, ≥1 tophi and ≥2 flares in the last 12 months, and history of xanthine oxidase inhibitor treatment. RESULTS: Twenty-five out of 312 (8.0%) gout patients had a history of KT. Univariate analysis found that patients with gout and history of kidney transplants had: greater prevalence of severe uncontrolled gout (27% vs 8%, P = .007) and tophi (36% vs 17%, P = .030), and higher rates of failure or physician perceived contraindication to allopurinol (44% vs 23%, P = .028). CONCLUSION: This study provides preliminary evidence that gout in patients with history of KT is more severe and poses greater challenges to pharmacologic management. Although gout has been linked to worse outcomes among kidney recipients in the literature, there are presently no publications on gout severity among patients with KT in comparison to other patients with gout. Further investigation of disease severity and appropriate, effective treatment options in recipients of kidney transplant with a diagnosis of gout, especially prior to the transplant, is warranted.

Addressing the risk of bacterial contamination in platelets: a hospital economic perspective.

BACKGROUND: Bacterially contaminated platelets (PLTs) remain a serious risk. The Food and Drug Administration has issued draft guidance recommending hospitals implement secondary testing or transfuse PLTs that have been treated with pathogen reduction technology (PRT). The cost implications of these approaches are not well understood. STUDY DESIGN AND METHODS: We modeled incurred costs when hospitals acquire, process, and transfuse PLTs that are PRT treated with INTERCEPT (Cerus Corp.) or secondary tested with the PLT PGD Test (Verax Biomedical). RESULTS: Hospitals will spend $221.27 (30.0%) more per PRT-treated apheresis PLT unit administered compared to a Zika-tested apheresis PLT unit that is irradiated and PGD tested in hospital. This difference is reflected in PRT PLT units having: 1) a higher hospital purchase price ($100.00 additional charge compared to an untreated PLT); 2) lower therapeutic effectiveness than untreated PLTs among hematologic-oncologic patients, which contributes to additional transfusions ($96.05); or 3) fewer PLT storage days, which contributes to higher outdating cost from expired PLTs ($67.87). Only a small portion of the incremental costs for PRT-treated PLTs are offset by costs that may be avoided, including primary bacterial culture, secondary bacterial testing ($26.65), hospital irradiation ($8.50), Zika testing ($4.47), and other costs ($3.03). CONCLUSION: The significantly higher cost of PRT-treated PLTs over PGD-tested PLTs should interest stakeholders. For hospitals that outdate PLTs, savings associated with expiration extension to 7 days by adding PGD testing will likely be substantially greater than the cost of implementing PGD-testing. Our findings might usefully inform a hospital's decision to select a particular blood safety approach.

Perceptions of medical errors in cancer care: an analysis of how the news media describe sentinel events.

OBJECTIVE: To analyze the print news media's coverage of sentinel events involving cancer patients. METHODS: Using LexisNexis, we identified English-language newspaper articles covering medical errors in cancer care between January 1, 2000, and December 31, 2010. Articles were coded for 3 major themes using a standardized abstraction instrument: narrative statements and point of view most prominently represented, attribution of blame, and orientation toward patient safety. We also abstracted country where the newspaper was published, type of error event, and extent of patient harm. RESULTS: We analyzed 64 articles from 37 print newspaper syndications that circulated in 6 countries/regions. Reports of medical errors rarely were framed from the point of view of a safety expert or the responsible clinician (13% and 3%, respectively) compared with the patient and legal points of view (both 30%). Articles held individual clinicians (41%) and hospital systems (28%) responsible for most errors. Four in 10 articles failed to present medical errors as "systems" problems. Article perspective varied considerably by country, with 53% of articles from the UK and 63% from Australia and New Zealand judged as negatively slanted compared with 14% in the United States and Canada. CONCLUSIONS: In reports of medical errors involving cancer patients, the news media regularly blame individual clinicians for mistakes and fail to present a systems-based understanding of these events.

Disparities in evaluation of patients with rectal bleeding 40 years and older.

BACKGROUND & AIMS: Rectal bleeding is associated with colorectal cancer. We characterized the evaluation of patients aged 40 years and older with rectal bleeding and identified characteristics associated with inadequate evaluation. METHODS: We conducted a retrospective review of records of outpatient visits that contained reports of rectal bleeding for patients aged 40 years and older (N = 480). We studied whether patient characteristics affected whether or not they received a colonoscopy examination within 90 days of presentation with rectal bleeding. Patient characteristics included demographics; family history of colon cancer and polyps; and histories of screening colonoscopies, physical examinations, referrals to specialists at the index visit, and communication of laboratory results. Data were collected from medical records, and patient income levels were estimated based on Zip codes. RESULTS: Nearly half of the patients presenting with rectal bleeding received colonoscopies (48.1%); 81.7% received the procedure within 90 days. A history of a colonoscopy examination was more likely to be reported in white patients compared with Hispanic or Asian patients (P = .012 and P = .006, respectively), and in high-income compared with low-income patients (P = .022). A family history was more likely to be documented among patients with private insurance than those with Medicaid or Medicare (P = .004). A rectal examination was performed more often for patients who were white or Asian, male, and with high or middle incomes, compared with those who were black, Hispanic, female, or with low incomes (P = .027). White patients were more likely to have their laboratory results communicated to them than black patients (P = .001). CONCLUSIONS: Sex, race, ethnicity, patient income, and insurance status were associated with disparities in evaluation of rectal bleeding. There is a need to standardize the evaluation of patients with rectal bleeding.

Multisite parent-centered risk assessment to reduce pediatric oral chemotherapy errors.

PURPOSE: Observational studies describe high rates of errors in home oral chemotherapy use in children. In hospitals, proactive risk assessment methods help front-line health care workers develop error prevention strategies. Our objective was to engage parents of children with cancer in a multisite study using proactive risk assessment methods to identify how errors occur at home and propose risk reduction strategies. METHODS: We recruited parents from three outpatient pediatric oncology clinics in the northeast and southeast United States to participate in failure mode and effects analyses (FMEA). An FMEA is a systematic team-based proactive risk assessment approach in understanding ways a process can fail and develop prevention strategies. Steps included diagram the process, brainstorm and prioritize failure modes (places where things go wrong), and propose risk reduction strategies. We focused on home oral chemotherapy administration after a change in dose because prior studies identified this area as high risk. RESULTS: Parent teams consisted of four parents at two of the sites and 10 at the third. Parents developed a 13-step process map, with two to 19 failure modes per step. The highest priority failure modes included miscommunication when receiving instructions from the clinician (caused by conflicting instructions or parent lapses) and unsafe chemotherapy handling at home. Recommended risk assessment strategies included novel uses of technology to improve parent access to information, clinicians, and other parents while at home. CONCLUSION: Parents of pediatric oncology patients readily participated in a proactive risk assessment method, identifying processes that pose a risk for medication errors involving home oral chemotherapy.

US Cancer Center Implementation of ASCO/Oncology Nursing Society Chemotherapy Administration Safety Standards.

PURPOSE: Because cancer chemotherapy is a high-risk intervention, ASCO and the Oncology Nursing Society (ONS) established in 2009 consensus- and evidence-based national standards for the safe administration of chemotherapy. We sought to assess the implementation status of the ASCO/ONS chemotherapy administration safety standards. METHODS: A written survey of chemotherapy practices was sent to National Cancer Institute-designated cancer centers. Implementation status of each of 31 chemotherapy administration safety standards was self-reported. RESULTS: Forty-four (80%) of 55 eligible centers responded. Although the majority of centers have fully implemented at least half of the standards, only four centers reported full implementation of all 31. Implementation varied by standard, with the poorest implementation of standards that addressed documentation of chemotherapy planning, agreed-on intervals for laboratory testing, and patient education and consent before initiation of oral or infusional chemotherapy. CONCLUSION: Given wide variation in the implementation of ASCO/ONS chemotherapy administration safety standards at US cancer centers, there are significant opportunities for improvement.
