Penicillin allergy skin testing as an antibiotic stewardship intervention reduces alternative antibiotic exposures in hematopoietic stem cell transplant recipients.

BACKGROUND: Antibiotic allergy de-labeling using penicillin allergy skin testing (PAST) can reduce the use and cost of alternative, non-ß-lactam antibiotics in general inpatient populations. This strategy's role in hematopoietic stem cell transplant (HSCT) recipients is unclear. METHODS: This study aimed to determine the effect of a pre-transplant PAST protocol on antibiotic use, days of therapy (DOT), and cost in an immunocompromised population at a single center from 7/1/2010-2/1/2019. Patients who received chimeric antigen receptor (CAR) T-cell therapy and those who underwent transplantation in the outpatient setting were excluded. RESULTS: Of 1560 patients who underwent inpatient HSCT during the study period, 208 reported ß-lactam allergy (136/844 [16%] pre- and 72/716 [10%] post-implementation; P < .001). PAST was performed on 7% and 54% of HSCT recipients pre- and post-implementation, respectively. Only two positive PAST were noted. There were no adverse reactions to PAST. There were no significant differences in the disease and transplant characteristics between the two groups. Days of therapy and cost of alternative antibiotics significantly decreased post-implementation (mean 788 vs 627 days, P = .01; mean $24 425 vs $17 518, P = .009). CONCLUSION: Penicillin allergy skin testing adjudicates reported ß-lactam allergy in HSCT recipients, lowering use, DOT, and cost of alternative antibiotics and promoting effective formulary agents to treat immunocompromised HSCT recipients.

Patient-reported outcomes in systemic AL amyloidosis with functional assessment of cancer therapy-general (FACT-G) and patient-reported outcomes measurement information system-global health (PROMIS-GH) in a real-world population.

We performed an observational study on health-related quality of life (HRQoL) in patients with AL amyloidosis diagnosed between 2012 and 2017 at our institution. A total of 81 patients were included, with a median age of 64 years. The mean FACT-G (Functional Assessment of Cancer Therapy-General) total score at baseline (≤2 months from diagnosis) was 74 (±15), compared to a normative score of 80 (±18) in the general U.S. population. Significant HRQoL deficit was noted only in the functional well-being (FWB) domain of FACT-G. Using PROMIS-GH (Patient-Reported Outcomes Measurement Information System-Global Health) at baseline (n = 18), a greater deficit was noted in the global physical health (GPH) compared to global mental health (GMH) domain. FACT-FWB and PROMIS-GPH domain scores were able to significantly discriminate between revised Mayo stages. Development and validation of an amyloid-specific PRO instrument incorporating specific domains of interest is urgently needed to pursue patient-centered drug development.

Psychosocial Assessment of Candidates for Transplant (PACT) as a tool for psychological and social evaluation of allogeneic hematopoietic cell transplantation recipients.

Psychosocial Assessment of Candidates for Transplant (PACT) is a tool originally developed to address psychosocial risks in solid organ transplant recipients and has the potential for application to hematopoietic cell transplantation (HCT) recipients. In a retrospective cohort study, we reviewed 404 adult allogeneic HCT cases from 2003 to 2014 to identify predictors of adverse psychosocial status as determined by PACT. Final PACT rating was poor/borderline (score 0-1) in 5%, acceptable (score 2) in 22%, good (score 3) in 44%, and excellent (score 4) in 29% recipients. In multivariable regression, higher PACT score was associated with White race (odds ratio [OR] 2.95, P < 0.001), having a related donor (OR 1.61, P = 0.015), and a higher quality of life score (OR 1.22/ 10-point increase in FACT-BMT total score, P < 0.001). PACT score correlated with all quality of life subscales. The final PACT score was associated with non-relapse mortality (HR 0.82/ 1-point increase, p = 0.03) in multivariable analysis that considered patient and disease factors, but not in models that also included transplant-related factors and performance status. PACT score was not associated with overall survival. PACT can be considered as part of a comprehensive psychosocial assessment for identifying patients who may require additional resources around allogeneic HCT.

Community Risk Score for Evaluating Health Care Disparities in Hematopoietic Cell Transplantation.

There is a critical need for tools to comprehensively describe disparities in hematopoietic cell transplant (HCT) recipients. We conducted a retrospective cohort study to evaluate a Community Risk Score (CRS) tool for this purpose. CRS included 10 community health indicators based on county or state of residence obtained from several secondary data sources and a composite score was assigned to each county (range 0 to 40), that was further categorized into six tiers (I to VI) with higher tiers indicating poor community health. CRS was assessed for 509 allogeneic and 1033 autologous HCT recipients from 2003 to 2013. Our cohort represented allogeneic and autologous HCT recipients from 300 and 431 unique ZIP codes from 99 and 125 counties in 15 and 16 states, although 86% and 90% patients were from Ohio, respectively. A greater proportion of patients had adverse individual community risk indicators in higher-risk tiers (P < .001 for trend for all). In multivariable analysis, clear trends toward association of CRS with outcomes were not observed. For autologous HCTs, Tier III has higher risks of relapse mortality (hazard ratio [HR] 2.2, P = .02) and all-cause mortality (HR 1.8, P = 0.03). In conclusion, CRS was able to categorize patients into groups representing greater levels of health care disparities. We did not see a clear association between CRS and transplant outcomes, although our cohort was limited to a relatively small group of counties. Community-based risk score model may serve as a tool for evaluating disparities in HCT recipients, but its validation in a nationally representative cohort of patients is needed.

Association of Socioeconomic Status with Chronic Graft-versus-Host Disease Outcomes.

Chronic graft-versus host disease (GVHD) is a chronic and disabling complication after hematopoietic cell transplantation (HCT). It is important to understand the association of socioeconomic status (SES) with health outcomes in patients with chronic GVHD because of the impaired physical health and dependence on intensive and prolonged health care utilization needs in these patients. We evaluated the association of SES with survival and quality of life (QOL) in a cohort of 421 patients with chronic GVHD enrolled on the Chronic GVHD Consortium Improving Outcomes Assessment study. Income, education, marital status, and work status were analyzed to determine the associations with patient-reported outcomes at the time of enrollment, nonrelapse mortality (NRM), and overall mortality. Higher income (P = .004), ability to work (P < .001), and having a partner (P = .021) were associated with better mean Lee chronic GVHD symptom scores. Higher income (P = .048), educational level (P = .044), and ability to work (P < .001) also were significantly associated with better QOL and improved activity. In multivariable models, higher income and ability to return to work were both significantly associated with better chronic GVHD Lee symptom scores, but income was not associated with activity level, QOL, or physical/mental functioning. The inability to return to work (hazard ratio, 1.82; P = .019) was associated with worse overall mortality, whereas none of the SES indicators were associated with NRM. Income, race, and education did not have statistically significant associations with survival. In summary, we did not observe an association between SES variables and survival or NRM in patients with chronic GVHD, although we found some association with patient-reported outcomes, such as symptom burden. Higher income status was associated with less severe chronic GVHD symptoms. More research is needed to understand the psychosocial, biological, and environmental factors that mediate this association of SES with major HCT outcomes.

Predicting risk of venous thromboembolism in hospitalized cancer patients: Utility of a risk assessment tool.

Inpatient venous thromboembolism (VTE) is a priority preventable illness; risk in cancer varies and prophylaxis is inconsistently used. A previously validated tool (Khorana Score, [KS]) identifies VTE risk in cancer outpatients with 5 easily available variables but has not been studied in the inpatient setting. We evaluated the validity of KS in predicting VTE risk in hospitalized cancer patients. We conducted a retrospective cohort study of consecutive oncology inpatients at the Cleveland Clinic from 11/2012 to 12/2014 (n = 3531). Patients were excluded for VTE on admission (n = 304), incomplete KS data (n = 439) or other reasons (n = 8). Data collected included demographics, cancer type, length of stay (LOS), anticoagulant use, and laboratory values. Multivariate risk factors were identified with stepwise logistic regression, confirmed with bootstrap analysis. Of 2780 patients included, 106 (3.8%) developed VTE during hospitalization. Median age was 62 (range, 19-98) years and 56% were male. Median LOS was 5 (range, 0-152) days. High risk KS (≥ 3) was significantly associated with VTE in uni- and multivariate analyses (OR 2.5, 95% [confidence interval] CI 1.3-4.9). Other significant variables included male gender (OR 1.67, 1.1-2.53), older age (OR 0.86, 0.75-0.99) and use of anticoagulants (OR 0.57, 0.39-0.85). Recursive partitioning analysis suggested optimal cut point for KS is 2 (OR 1.82, 1.23-2.69). This is the first report validating KS as a risk tool to predict VTE in hospitalized cancer patients. Using this tool could lead to more consistent and successful application of inpatient thromboprophylaxis.

Association of Socioeconomic Status with Outcomes of Autologous Hematopoietic Cell Transplantation for Multiple Myeloma.

Autologous hematopoietic cell transplantation (AHCT) is standard therapy for eligible patients with multiple myeloma. Health care disparities can influence transplantation outcomes. However, the association of socioeconomic status (SES), a major indicator of health care disparities, with outcomes in patients with myeloma after AHCT has not been previously described. We analyzed 346 consecutive AHCT recipients with myeloma who underwent transplantation between 2003 and 2013 in this retrospective cohort study. Zip code of residence at the time of AHCT was obtained to assess annual household income based on 2010 US census data (median, $49,054; range, $16,546 to $127,313). SES groups were divided into < $45,000 (low; n = 120), $45,000 to $60,000 (middle; n = 116), and > $60,000 (high; n = 110). The low-income cohort had smallest portion of Caucasians (69% versus 89% versus 91%); otherwise, patient, disease, and transplantation characteristics were comparable among cohorts or different without significant patterns found. Median follow-up was 49 months. There was no difference among SES groups in overall survival, progression-free survival, nonrelapse mortality, or relapse in univariate and multivariable analysis. Similarly, SES was not associated with survival in a subset analysis of 303 patients who had survived for 1 year after transplantation.

Assessment of clinical workload for general and specialty genetic counsellors at an academic medical center: a tool for evaluating genetic counselling practices.

With genomics influencing clinical decisions, genetics professionals are exponentially called upon as part of multidisciplinary care. Increasing demand for genetic counselling, a limited workforce, necessitates practices improve efficiency. We hypothesised that distinct differences in clinical workload exist between various disciplines of genetic counselling, complicating practice standardisation and patient volume expectations. We thus sought to objectively define and assess workload among various specialties of genetic counselling. Twelve genetic counsellors (GCs), representing 9.3 clinical FTE, in general or specialty (cancer, cardiovascular or prenatal) services at an academic health system developed a data collection tool for assessing time and complexity. Over a 6-week period, the data were recorded for 583 patient visits (136 general and 447 specialty) and analysed comparing general versus specialty GCs. Variables were compared with hierarchical linear models for ordinal or continuous data and hierarchical logistic models for binary data. General GCs completed more pre- and post-visit activities (P=0.011) and spent more time (P=0.009) per case. General GCs reported greater case discussion with other providers (P<0.001), literature review (P=0.026), exploring testing options (P=0.041), electronic medical record review (P=0.040), insurance preauthorization (P=0.05) and fielding patient inquiries (P=0.003). Lesser redundancy in referral indication was observed by general GCs. GCs in general practice carry a higher pre- and post-visit workload compared with GCs in specialty practices. General GCs may require lower patient volumes than specialty GCs to allow time for additional pre- and post-visit activities. Non-clinical activities should be transferred to support staff.

Ocular adnexal lymphoma: assessment of a tumor-node-metastasis staging system.

PURPOSE: To assess distribution, correlations, and prognostic effect of tumor (T), node (N), and metastasis (M) staging on relapse and survival. DESIGN: Retrospective clinical review. PARTICIPANTS: Sixty-three patients diagnosed with primary ocular adnexal lymphoma (OAL) between January 1986 and November 2011. METHODS: Complete ocular examination and systemic evaluation were performed. Patients were staged according to the American Joint Committee on Cancer (AJCC) seventh edition tumor-node-metastasis (TNM) clinical staging system for OAL and followed every 6 to 12 months (median follow-up, 27.9 months). MAIN OUTCOME MEASURES: Relapse defined as lymphoma recurrence in the initial site of presentation, the contralateral ocular adnexal structures, or other systemic site and overall survival. RESULTS: There were 40 men (63.5%). The median age was 65 years (range, 24-85 years). The affected site was the conjunctiva in 27 patients (42.9%), orbit in 38 patients (60.3%), and eyelid in 3 patients (4.8%). The histologic subtype was extranodal marginal zone lymphoma (EMZL) in 51 patients (81.0%). A total of 14 patients (23.3%) had T1, 42 patients (70.0%) had T2, 1 patient (1.7%) had T3, and 3 patients (5.0%) had T4 disease. A total of 48 patients (82.8%) had N0 disease, and 10 patients (17.2%) had N1-4 disease. M stage was M0 in 47 patients (81.0%) and M1 in 11 patients (19.0%). With advanced T stage, there was an increase in both N1-4 (P = 0.045) and M1 disease (P = 0.041). M1 disease was greater among patients with N1-4 disease compared with N0 stage (50.0% vs. 12.5%, P = 0.003). Overall, 18 patients (28.6%) relapsed and 6 patients (9.5%) died. In Cox analysis, relapse was not associated with T stage (hazard ratio [HR], 1.14 per 1 level increase, P = 0.71), N stage (HR, 1.47; P = 0.51 N1-4 vs. N0), or M stage (HR, 1.22; P = 0.76 M1 vs. M0). T stage was not associated with survival (HR, 0.86; P = 0.81), whereas N1-4 had marginally worse survival than N0 (HR, 5.35; P = 0.07), and M1 had worse survival than M0 (HR, 9.27; P = 0.008). CONCLUSIONS: The TNM staging system for primary OAL is useful for precise characterization of extent of local disease. Although T stage does not predict relapse or survival, N1-4 and M1 stages indicated less favorable survival.

Esophageal submucosa: the watershed for esophageal cancer.

OBJECTIVES: Submucosal esophageal cancers (pT1b) are considered superficial, implying good survival. However, some are advanced, metastasizing to regional lymph nodes. Interplay of cancer characteristics and lymphatic anatomy may create a watershed, demarcating low-risk from high-risk cancers. Therefore, we characterized submucosal cancers according to depth of invasion and identified those with high likelihood of lymph node metastases and poor survival. METHODS: From 1983 to 2010, 120 patients underwent esophagectomy for submucosal cancers at Cleveland Clinic. Correlations were sought among cancer characteristics (location, dimensions, histopathologic cell type, histologic grade, and lymphovascular invasion [LVI]), and their associations with lymph node metastasis were identified by logistic regression. Associations with mortality were identified by Cox regression. RESULTS: As submucosal invasion increased, cancer length (P < .001), width (P < .001), area (P < .001), LVI (P = .007), and grade (P = .05) increased. Invasion of the deep submucosa (P < .001) and LVI (P = .06) predicted lymph node metastases: 45% (23/51) of deep versus 10% (3/29) of middle-third and 7.5% (3/40) of inner-third cancers had lymph node metastases, as did 46% (12/26) with LVI versus 18% (17/94) without. Older age and lymph node metastases predicted worse 5-year survival: 94% for younger pN0 patients, 62% for older pN0 patients, and 36% for pN1-2 patients regardless of age. CONCLUSIONS: Submucosal cancer characteristics and lymphatic anatomy create a watershed for regional lymph node metastases in the deep submucosa. This previously unrecognized divide distinguishes superficial submucosal cancers with good survival from deep submucosal cancers with poor survival. Aggressive therapy of more superficial cancers is critical before submucosal invasion occurs.

Clinical predictors and algorithm for the genetic diagnosis of pheochromocytoma patients.

PURPOSE: Six pheochromocytoma susceptibility genes causing distinct syndromes have been identified; approximately one of three of all pheochromocytoma patients carry a predisposing germline mutation. When four major genes (VHL, RET, SDHB, SDHD) are analyzed in a clinical laboratory, costs are approximately $3,400 per patient. The aim of the study is to systematically obtain a robust algorithm to identify who should be genetically tested, and to determine the order in which genes should be tested. EXPERIMENTAL DESIGN: DNA from 989 apparently nonsyndromic patients were scanned for germline mutations in the genes VHL, RET, SDHB, SDHC, and SDHD. Clinical parameters were analyzed as potential predictors for finding mutations by multiple logistic regression, validated by bootstrapping. Cost reduction was calculated between prioritized gene testing compared with that for all genes. RESULTS: Of 989 apparently nonsyndromic pheochromocytoma cases, 187 (19%) harbored germline mutations. Predictors for presence of mutation are age <45 years, multiple pheochromocytoma, extra-adrenal location, and previous head and neck paraganglioma. If we used the presence of any one predictor as indicative of proceeding with gene testing, then 342 (34.6%) patients would be excluded, and only 8 carriers (4.3%) would be missed. We were also able to statistically model the priority of genes to be tested given certain clinical features. E.g., for patients with prior head and neck paraganglioma, the priority would be SDHD>SDHB>RET>VHL. Using the clinical predictor algorithm to prioritize gene testing and order, a 44.7% cost reduction in diagnostic process can be achieved. CONCLUSIONS: Clinical parameters can predict for mutation carriers and help prioritize gene testing to reduce costs in nonsyndromic pheochromocytoma presentations.

Clinical predictors for germline mutations in head and neck paraganglioma patients: cost reduction strategy in genetic diagnostic process as fall-out.

Multiple genes and their variants that lend susceptibility to many diseases will play a major role in clinical routine. Genetics-based cost reduction strategies in diagnostic processes are important in the setting of multiple susceptibility genes for a single disease. Head and neck paraganglioma (HNP) is caused by germline mutations of at least three succinate dehydrogenase subunit genes (SDHx). Mutation analysis for all 3 costs approximately US$2,700 per patient. Genetic classification is essential for downstream management of the patient and preemptive management of family members. Utilizing HNP as a model, we wanted to determine predictors to prioritize the most heritable clinical presentations and which gene to begin testing in HNP presentations, to reduce costs of genetic screening. Patients were tested for SDHB, SDHC, and SDHD intragenic mutations and large deletions. Clinical parameters were analyzed as potential predictors for finding germline mutations. Cost reduction was calculated between prioritized gene testing compared with that for all genes. Of 598 patients, 30.6% had SDHx germline mutations: 34.4% in SDHB, 14.2% SDHC, and 51.4% SDHD. Predictors for an SDHx mutation are family history [odds ratio (OR), 37.9], previous pheochromocytoma (OR, 10.9), multiple HNP (OR, 10.6), age

Symptom evaluation in palliative medicine: patient report vs systematic assessment.

PURPOSE: This study examined symptoms reported by patients after open-ended questioning vs those systematically assessed using a 48-question survey. MATERIALS AND METHODS: Consecutive patients referred to the palliative medicine program at the Cleveland Clinic Foundation were screened. Open-ended questions were asked initially followed by a 48-item investigator-developed symptom checklist. Each symptom was rated for severity as mild, moderate, or severe. Symptom distress was also evaluated. Data were collected using standardized pre-printed forms. RESULTS: Two hundred and sixty-five patients were examined and 200 were eligible for assessment. Of those assessed, the median age was 65 years (range 17-90), and median ECOG performance status was 2 (range 1-4). A total of 2,397 symptoms were identified, 322 volunteered and 2,075 by systematic assessment. The median number of volunteered symptoms was one (range zero to six). Eighty-three percent of volunteered symptoms were moderate or severe and 17% mild. Ninety-one percent were distressing. Fatigue was the most common symptom identified by systematic assessment but pain was volunteered most often. The median number of symptoms found using systematic assessment was ten (0-25). Fifty-two percent were rated moderate or severe and 48% mild. Fifty-three percent were distressing. In total, 69% of 522 severe symptoms and 79% of 1,393 distressing symptoms were not volunteered. Certain symptoms were more likely to be volunteered; this was unaffected by age, gender, or race. CONCLUSION: The median number of symptoms found using systematic assessment was tenfold higher (p<0.001) than those volunteered. Specific detailed symptom inquiry is essential for optimal palliation in advanced disease.

The financial benefits of acute inpatient palliative medicine: an inter-institutional comparative analysis by all patient refined-diagnosis related group and case mix index.

Financial comparisons of acute care hospital services are possible using the Centers for Medicare & Medicaid Services case mix index (CMI) and All Patient Refined-Diagnosis Related Group (APR-DRG) data. We compared The Cleveland Clinic's Inpatient Palliative Medicine (CCIPM) acute care unit's CMI and APR-DRG data with national and peer institution data. Total mean charges per admission to the CCIPM unit were 7,800 dollars lower than at other peer institutions despite an equivalent severity of illness and longer length of stay and higher mortality in the CCIPM unit. The lower charges were due primarily to lower laboratory and pharmaceutical charges. We conclude that an acute inpatient palliative medicine unit operating within a comprehensive integrated palliative medicine program is cost-effective in providing specialized care for people with advanced disease.

Race is a fundamental prognostic indicator for 2325 northeastern Ohio women with infiltrating breast cancer.

The goal of this research was to determine if race, independent of socioeconomic status, is a prognostic indicator for women diagnosed with infiltrating breast cancer. We hypothesized that black patients would present with breast cancers having less favorable prognostic indicators relative to white patients, regardless of socioeconomic status. Using data collected prospectively in our institutional review board approved breast center patient registry and 2000 Census Tract data for northeastern Ohio, we compared tumor size, node status, hormone receptor status, clinical outcomes, and socioeconomic status for patients who were self-described as either black or white and who had been diagnosed with infiltrating breast cancer. The chi-square test, t-test, log-rank test, and Cox proportional hazards analysis were used to analyze the data. Kaplan-Meier outcome curves were generated. Data were available for 2325 women, including 313 who were black and 2012 who were white. Compared to white patients, black patients were more likely to have positive axillary nodes and to have hormone receptor-negative tumors. Black patients were also more likely to have positive axillary nodes associated with smaller tumors. Independent of socioeconomic status, black patients were more likely to have poorer overall survival and disease-free survival rates for breast cancer relative to white patients. The prognostic significance of race was not dependent on a concomitant relationship with socioeconomic status.

Combined bronchoscopy, mediastinoscopy, and thoracotomy for lung cancer: who benefits?

OBJECTIVES: Surgical staging and resection of lung cancer may be done as 1 operation (combined) or 2 (staged). This study evaluates the safety and efficiency of these treatment strategies. METHODS: From 1998 to July 2001, 343 patients underwent bronchoscopy, mediastinoscopy, and thoracotomy without induction chemoradiotherapy by 3 surgeons. Fifty-seven patients were staged and 286 combined. Staged patients had higher clinical stage (P <.001). Propensity-matched groups were compared to adjust for this and other differences. Factors associated with safety and efficiency were identified by propensity-adjusted multivariable analysis. RESULTS: Mortality and morbidity were similar for both strategies. Efficiency, measured by shorter operative time (1.2 hours) and lower cost (25%), was better for combined strategy (P <.001). Hospital stay was similar, but revenue was 12% higher for the staged strategy (P <.001). In propensity-matched comparisons excluding surgeon, results were similar to the above. Comparisons including surgeon demonstrated similar cost and revenue for both strategies. Increased mortality and morbidity were associated only with patient and tumor characteristics: male gender, worsening Eastern Cooperative Oncology Group performance status, and increasing pathological node classification. All measures of efficiency worsened with increasing pathological classifications. Staged strategy was associated with increased operative time and revenue, while one surgeon and patient smoking history were associated with increased hospital stay and costs. CONCLUSIONS: The combined strategy provides efficient, safe health care for clinically operable lung cancer patients, but it may not be as financially rewarding as the staged strategy. Treatment strategy is only 1 of many determinants of efficiency.

The business of palliative medicine--Part 2: The economics of acute inpatient palliative medicine.

Economic feasibility is a major factor in the viability of established acute inpatient palliative medicine. Several clinical, administrative, and financial parameters determine the financial health of inpatient care. Financial management metrics include case mix index (CMI) (as determined by the Federal Register as an assigned relative weight to the diagnosis-related group (DRG) reflecting resource consumption), direct costs, indirect costs, contribution margin, and in the future of all patient revised-DRG (APR-DRG). Both census and length of stay will have a major impact on these financial metrics. The type of patient referral and clinical decisions will influence direct costs and revenues. In the future, an international CMI or APR-DRG will allow palliative inpatient units to compare disease severity, resource utilization, and outcome measures.
