The National Hospital Care Survey is a unique source of data on rare diseases
Strashny A , Alford J , Rappole C , Santo L . Value Health 2022 OBJECTIVES: This study aims to demonstrate the usefulness of the National Hospital Care Survey (NHCS) for studying rare diseases. METHODS: NHCS contains data on millions of hospital patients from participating US hospitals, including diagnoses coded using 10th revision of International Classification of Diseases, Clinical Modification, making it likely that some of the patients have a diagnosed rare disease. The data for 2016 are unweighted and are not nationally representative. The Orphanet Nomenclature Pack lists 877 10th revision of the International Classification of Diseases codes that correspond to 536 rare diseases. Using Orphanet Nomenclature Pack, we identified NHCS patients with diagnosed rare diseases. We demonstrate the usefulness of NHCS for studying rare diseases by reporting, for each rare disease, the number of patients in NHCS with the disease, the average number of hospital encounters per patient, the average length of hospital stay, and the percent of patients who died either in-hospital or within 90 days after discharge. RESULTS: In just 1 year of NHCS, we identified hundreds of rare diseases with ≥30 patients each (313 rare diseases in the inpatient setting and 273 in the emergency department setting). Although 10th revision of the International Classification of Diseases, Clinical Modification codes identify a small percent of known rare diseases, 12.9% of inpatient patients and 3.4% of emergency department patients had a diagnosed rare disease. CONCLUSIONS: NHCS is a rich source of administrative and electronic health record data on hospital patients with rare diseases, providing unique variables and observations on many patients. Although the percent of patients with each rare disease is low, a large percent of hospital patients has a rare disease. |
NIOSH's Respiratory Health Division: 50 years of science and service
Cummings KJ , Johns DO , Mazurek JM , Hearl FJ , Weissman DN . Arch Environ Occup Health 2018 74 1-15 The year 2017 marked the 50th anniversary of NIOSH's Respiratory Health Division (RHD). RHD began in 1967 as the Appalachian Laboratory for Occupational Respiratory Diseases (ALFORD), with a focus on coal workers' pneumoconiosis. ALFORD became part of NIOSH in 1971 and added activities to address work-related respiratory disease more generally. Health hazard evaluations played an important role in understanding novel respiratory hazards such as nylon flock, diacetyl, and indium-tin oxide. Epidemiologic and laboratory studies addressed many respiratory hazards, including coal mine dust, silica, asbestos, cotton dust, beryllium, diesel exhaust, and dampness and mold. Surveillance activities tracked the burden of diseases and enhanced the quality of spirometry and chest radiography used to screen workers. RHD's efforts to improve scientific understanding, inform strategies for prevention, and disseminate knowledge remain important now and for the future. |
A review of public health training needs assessment approaches: Opportunities to move forward
Joly BM , Coronado F , Bickford BC , Leider JP , Alford A , McKeever J , Harper E . J Public Health Manag Pract 2018 24 (6) 571-577 CONTEXT: Assessing training needs of the public health workforce is crucial for creating professional development opportunities to improve knowledge, competence, and effectiveness of this workforce. DISSEMINATION: Regional Public Health Training Centers (RPHTCs) assess workforce training needs and deliver training based on identified needs. To determine training priorities, several needs assessment surveys have been administered by RPHTCs and national public health member organizations. EVALUATION: This study identified the types of training questions being asked to public health practitioners in the various assessment surveys implemented by RPHTCs and national membership organizations. Although the surveys measured similar overarching constructs, multiple approaches with limited consistency were used to measure training needs. DISCUSSION: Although successful in responding to the needs of their targeted constituents, the limited consistency among survey types makes generalization of findings difficult. Disseminating common metrics and aggregate survey findings would increase efficiency in determining workforce training needs and developing targeted training. |
Cancer screening among a population-based sample of insured women
Alford SH , Leadbetter S , Rodriguez JL , Hawkins NA , Scholl LE , Peipins LA . Prev Med Rep 2015 2 15-20 PURPOSE: Screening has been shown to lower the morbidity and mortality for breast, cervical, and colorectal cancers. Despite the availability of cancer screening, nearly 70,000 women die each year from these cancers. We conducted a study in 2008 within a privately-insured patient population of women who were members of an integrated health care system in Southeastern Michigan, for whom information on ovarian cancer risk as well as personal and family history of cancer was available. METHODS: We used a population-based, weighted stratified random sample of women from a single health care institution to assess the proportion with up-to-date breast, cervical, and colorectal screening. Multivariable analyses were conducted to identify predictors of screening behavior. RESULTS: In our study, women reported cervical and breast cancer screening above 90% and colorectal cancer screening above 75%. CONCLUSIONS: The results of our study hold promise that Healthy People 2020 cancer screening objectives might be obtainable as access to health insurance is expanded among US residents. |
Effectiveness of practices for improving the diagnostic accuracy of non ST elevation myocardial infarction in the emergency department: a Laboratory Medicine Best Practices systematic review
Layfield C , Rose J , Alford A , Snyder SR , Apple FS , Chowdhury FM , Kontos MC , Newby LK , Storrow AB , Tanasijevic M , Leibach E , Shaw C , Liebow EB , Christenson RH . Clin Biochem 2015 48 204-12 OBJECTIVES: This article is a systematic review of the effectiveness of four practices (assay selection, decision point cardiac troponin (cTn) threshold selection, serial testing, and point of care testing) for improving the diagnostic accuracy Non-ST-Segment Elevation Myocardial Infarction (NSTEMI) in the Emergency Department. DESIGN AND METHODS: The CDC-funded Laboratory Medicine Best Practices (LMBP) Initiative systematic review method for quality improvement practices was used. RESULTS: The current ACC/AHA guidelines recommend using cardiac troponin assays with a 99th percentile upper reference limit (URL) diagnostic threshold to diagnose NSTEMI. The evidence in this systematic review indicates that contemporary sensitive cTn assays meet the assay profile requirements (sensitivity, specificity, PPV, and NPV) to more accurately diagnose NSTEMI than alternate tests. Additional biomarkers did not increase diagnostic effectiveness of cTn assays. Sensitivity, specificity, and NPV were consistently high and low PPV improved with serial sampling. Evidence for use of point of care cTn testing was insufficient to make recommendation, though some evidence suggests that use may result in reduction to patient length of stay and costs. CONCLUSIONS: Based on the review of and the LMBP recommendation criteria, we recommend the use of cardiac troponin assays without additional biomarkers using the 99th percentile URL as the clinical diagnostic threshold for the diagnosis of NSTEMI. We recommend serial sampling with one sample at presentation and at least one additional second sample taken at least 6h later to identify a rise or fall in the troponin level. No recommendation is made either for or against the use of point of care tests.

Characteristics associated with genetic counseling referral and BRCA1/2 testing among women in a large integrated health system.
Bellcross CA , Peipins LA , McCarty FA , Rodriguez JL , Hawkins NA , Hensley Alford S , Leadbetter S . Genet Med 2014 17 (1) 43-50 BACKGROUND: Evidence shows underutilization of cancer genetics services. To explore the reasons behind this underutilization, this study evaluated characteristics of women who were referred for genetic counseling and/or had undergone BRCA1/2 testing. METHODS: An ovarian cancer risk perception study stratified 16,720 eligible women from the Henry Ford Health System into average-, elevated-, and high-risk groups based on family history. We randomly selected 3,307 subjects and interviewed 2,524 of them (76.3% response rate). RESULTS: Among the average-, elevated-, and high-risk groups, 2.3, 10.1, and 20.2%, respectively, reported genetic counseling referrals, and 0.8, 3.3, and 9.5%, respectively, reported having undergone BRCA testing. Personal breast cancer history, high risk, and perceived ovarian cancer risk were associated with both referral and testing. Discussion of family history with a doctor predicted counseling referral, whereas belief that family history influenced risk was the strongest BRCA testing predictor. Women perceiving their cancer risk as much higher than other women their age were twice as likely (95% confidence interval: 2.0-9.6) to report genetic counseling referral. CONCLUSION: In a health system with ready access to cancer genetic counseling and BRCA testing, women who were at high risk underutilized these services. There were strong associations between perceived ovarian cancer risk and genetic counseling referral, and between a belief that family history influenced risk and BRCA testing. |
Prevalence and healthcare actions of women in a large health system with a family history meeting the 2005 USPSTF recommendation for BRCA genetic counseling referral.
Bellcross CA , Leadbetter S , Alford SH , Peipins LA . Cancer Epidemiol Biomarkers Prev 2013 22 (4) 728-35 BACKGROUND: In 2005, the United States Preventive Services Task Force (USPSTF) released guidelines which outlined specific family history patterns associated with an increased risk for BRCA1/2 mutations, and recommended at-risk individuals be referred for genetic counseling and evaluation for BRCA testing. The purpose of this study was to assess the prevalence of individuals with a USPSTF increased-risk family history pattern, the frequency with which specific patterns were met, and resulting healthcare actions among women from the Henry Ford Health System. METHODS: As part of a study evaluating ovarian cancer risk perception and screening, 2,524 randomly selected participants completed a detailed interview (response rate 76%) from an initial eligible cohort of 16,720 women. RESULTS: Approximately 6% of participants had a family history fulfilling one or more of the USPSTF patterns. Although 90% of these women had shared their family history with their provider, less than 20% had been referred for genetic counseling and only 8% had undergone genetic testing. Caucasian women with higher income and education levels were more likely to receive referrals. Among the 95 participants in the total study cohort who reported BRCA testing, 78% did not have a family history that met one of the USPSTF patterns. CONCLUSIONS: These results suggest a higher prevalence of women with an increased-risk family history than originally predicted by the USPSTF, and lack of provider recognition and referral for genetic services. IMPACT: Improvements in healthcare infrastructure and clinician education will be required to realize population level benefits from BRCA genetic counseling and testing. |
Recruiting women for a study on perceived risk of cancer: influence of survey topic salience and early versus late response
Leadbetter S , Hawkins NA , Scholl LE , McCarty FA , Rodriguez JL , Freedner-Maguire N , Alford SH , Bellcross CA , Peipins LA . Prev Chronic Dis 2013 10 E75 INTRODUCTION: Understanding the characteristics of early and late survey responders has implications for recruitment efforts and for informing potential response bias. The main objective of this analysis was to examine survey responder status (ie, early vs late response) by sociodemographic characteristics and by salience of study variables among respondents. METHODS: We analyzed data from a survey on family cancer history and perceived cancer risk among women at a large managed health-care organization. For baseline and 12-month follow-up surveys, we defined early versus late responder status according to the 95th percentile of the number of days it took to obtain completed interviews. RESULTS: We found no significant associations between responder status and sociodemographic characteristics at baseline or follow-up. At baseline, early responders were significantly more likely than late responders to have a personal history of breast cancer (5.2% vs 3.4%, P = .04) and to have been referred for genetic counseling (4.6% vs 2.0%, P = .004). The association between personal history of breast cancer and responder status persisted at follow-up; only 3.5% of late responders at baseline were also late responders at follow-up. Follow-up survey nonresponse rates did not vary by baseline responder status. CONCLUSION: Survey topic salience is associated with early response and is important for recruitment. However, once recruited, late responders do not remain late responders at follow-up, suggesting that extra efforts made to recruit late responders are worthwhile. Health-related agencies that conduct surveys should consider survey salience in survey administration and recruitment strategies. |
