How do I reduce variation in red blood cell transfusion practices in a large integrated health care system?

BACKGROUND: Reducing variation in transfusion practices can prevent unwarranted transfusions, an outcome that improves quality of care and patient safety, while lowering costs and eliminating waste of blood. We developed and assessed a system-wide initiative to reduce variation in red blood cell (RBC) transfusion in terms of both transfusion utilization and the number of units transfused. INTERVENTION DESIGN AND METHODS: Our initiative combined a single-unit default order for RBC transfusion in hemodynamically stable, non-bleeding patients with a "Why Give 2 When 1 Will Do?" Choosing Wisely campaign, while also promoting a restrictive hemoglobin threshold (Hb <7 g/dl). This multimodal intervention was implemented across an academic medical center (AMC) with over 950 beds and 10 community hospitals. RESULTS: Between our baseline (CY 2020) and intervention period (CY 2021), single-unit orders increased from 57% to 70% of all RBC transfusion orders (p < .001). The greatest change in ordering practices was at community hospitals, where single-unit orders increased from 46% to 65% (p < .001). Over the same time period, the system-wide mean (SD) Hb result prior to transfusion fell from 7.3 (0.05) to 7.2 g/dl (0.04) (p < .05). We estimate this effort saved over 4000 units of blood and over $4 million in direct and indirect costs in its first year. DISCUSSION: By combining a single-unit default setting in the RBC order with a restrictive hemoglobin threshold, we significantly reduced variation in ordering practices. This effort demonstrates the value of single-unit policies and "nudges" in system-wide patient blood management initiatives.

The reliability of in-home measures of height and weight in large cohort studies: Evidence from Add Health.

BACKGROUND: With the emergence of obesity as a global health issue an increasing number of major demographic surveys are collecting measured anthropometric data. Yet little is known about the characteristics and reliability of these data. OBJECTIVES: We evaluate the accuracy and reliability of anthropometric data collected in the home during Wave IV of the National Longitudinal Study of Adolescent to Adult Health (Add Health), compare our estimates to national standard, clinic-based estimates from the National Health and Nutrition Examination Survey (NHANES) and, using both sources, provide a detailed anthropometric description of young adults in the United States. METHODS: The reliability of Add Health in-home anthropometric measures was estimated from repeat examinations of a random subsample of study participants. A digit preference analysis evaluated the quality of anthropometric data recorded by field interviewers. The adjusted odds of obesity and central obesity in Add Health vs. NHANES were estimated with logistic regression. RESULTS: Short-term reliabilities of in-home measures of height, weight, waist and arm circumference-as well as derived body mass index (BMI, kg/m2)-were excellent. Prevalence of obesity (37% vs. 29%) and central obesity (47% vs. 38%) was higher in Add Health than in NHANES while socio-demographic patterns of obesity and central obesity were comparable in the two studies. CONCLUSIONS: Properly trained non-medical field interviewers can collect reliable anthropometric data in a nationwide, home visit study. This national cohort of young adults in the United States faces a high risk of early-onset chronic disease and premature mortality.

Opportunities for increasing human papillomavirus vaccine provision in school health centers.

BACKGROUND: Uptake of human papillomavirus (HPV) vaccine remains low among adolescents in the United States. We sought to assess barriers to HPV vaccine provision in school health centers to inform subsequent interventions. METHODS: We conducted structured interviews in the fall of 2010 with staff from all 33 school health centers in North Carolina that stocked HPV vaccine. RESULTS: Centers had heterogeneous policies and procedures. Out-of-pocket costs for children and youth to receive privately purchased HPV vaccine were a key barrier to providing HPV vaccine within school health centers. Other barriers included students not returning consent forms, costs to clinics of ordering and stocking privately purchased HPV vaccine, and difficulty using the statewide immunization registry. Most (82%) school health centers were interested in hosting interventions to increase HPV vaccine uptake, especially those that the centers could implement themselves, but many had limited staff to support such efforts. Activities rated as more likely to raise HPV vaccine uptake were student incentives, parent reminders, and obtaining consent from parents while they are at school (all ps < .05). CONCLUSIONS: Although school health centers reported facing several key barriers to providing HPV vaccine, many were interested in partnering with outside organizations on low-cost interventions to increase HPV vaccine uptake among adolescents.

Early lessons learned from extramural school programs that offer HPV vaccine.

BACKGROUND: There has been little evaluation of school-located vaccination programs that offer human papillomavirus (HPV) vaccine in US schools without health centers (ie, extramural programs). This article summarizes lessons learned from such programs. METHODS: In July to August 2010, 5 programs were identified. Semistructured, in-depth telephone interviews were conducted with program representatives about practical aspects of planning and implementation, including configuration and effectiveness. RESULTS: Most programs offered HPV vaccine as part of a broader effort to increase uptake of adolescent vaccines. Respondents stressed the importance of building partnerships with local school systems throughout all aspects of the planning and implementation phases. All programs offered HPV vaccine at no cost to students. Most did not have a mechanism to bill private insurance, and some found Medicaid reimbursements to be a challenge. Programs achieved modest rates of initiation of the 3-dose HPV vaccine series (median 10%); however, among those who initiated the series, completion rates were high (median 78%). HPV vaccine uptake was lowest for a program that offered only HPV vaccine. CONCLUSIONS: Extramural programs may increase uptake of vaccines and decrease absenteeism due to noncompliance with vaccine requirements for school entry. Until extramural programs in the US receive better access to billing private insurers and Medicaid, sustainability of these programs relies on grant funding. Better integration of extramural school-located vaccine programs with existing local healthcare and other programs at schools is an area for growth.

Discordance in national estimates of hypertension among young adults.

BACKGROUND: In the United States, where coronary heart disease (CHD) is the leading cause of mortality, CHD risk assessment is a priority and accurate blood pressure (BP) measurement is essential. METHODS: Hypertension estimates in the National Longitudinal Study of Adolescent Health (Add Health), Wave IV (2008)-a nationally representative field study of 15,701 participants aged 24-32-was referenced against NHANES (2007-2008) participants of the same age. We examined discordances in hypertension, and estimated the accuracy and reliability of blood pressure in the Add Health study. RESULTS: Hypertension rates (BP: ≥ 140/90 mm Hg) were higher in Add Health compared with NHANES (19% vs. 4%), but self-reported history was similar (11% vs. 9%) among adults aged 24-32. Survey weights and adjustments for differences in participant characteristics, examination time, use of antihypertensive medications, and consumption of food/caffeine/cigarettes before blood pressure measurement had little effect on between-study differences in hypertension estimates. Among Add Health participants interviewed and examined twice (full and abbreviated interviews), blood pressure was similar, as was blood pressure at the in-home and in-clinic examinations conducted by NHANES III (1988-1994). In Add Health, there was minimal digit preference in blood pressure measurements; mean bias never exceeded 2 mm Hg; and reliability (estimated as intraclass correlation coefficients) was 0.81 and 0.68 for systolic and diastolic BPs, respectively. CONCLUSIONS: The proportion of young adults in NHANES reporting a history of hypertension was twice that with measured hypertension, whereas the reverse was found in Add Health. Between-survey differences were not explained by digit preference, low validity, or reliability of Add Health blood pressure data, or by salient differences in participant selection, measurement context, or interview content. The prevalence of hypertension among Add Health Wave IV participants suggests an unexpectedly high risk of cardiovascular disease among US young adults and warrants further scrutiny.

Best practices for preventing musculoskeletal disorders in masonry: stakeholder perspectives.

Brick masons and mason tenders report a high prevalence of work-related musculoskeletal disorders (WMSDs), many of which can be prevented with changes in materials, work equipment or work practices. To explore the use of "best practices" in the masonry industry, NIOSH organized a 2-day meeting of masonry stakeholders. Attendees included 30 industry representatives, 5 health and safety researchers, 4 health/safety specialists, 2 ergonomic consultants, and 2 representatives of state workers' compensation programs. Small groups discussed ergonomic interventions currently utilized in the masonry industry, including factors affecting intervention implementation and ways to promote diffusion of interventions. Meeting participants also identified various barriers to intervention implementation, including business considerations, quality concerns, design issues, supply problems, jobsite conditions and management practices that can slow or limit intervention diffusion. To be successful, future diffusion efforts must not only raise awareness of available solutions but also address these practical concerns.

Effects of safety and health training on work-related injury among construction laborers.

OBJECTIVES: This study was designed to evaluate the effects of safety and health training on work-related injury in the construction industry. METHODS: Union health insurance records, union training records, and workers compensation data for 1993 and 1994 were analyzed for more than 8000 construction laborers in Washington State. RESULTS: After controlling for demographic factors, laborers who received safety and health training during the study period were 12% (95% confidence interval [CI] = 0.75-1.02) less likely than nontrained laborers to file for workers compensation. Among workers 16 to 24 years old, training was associated with a 42% (95% CI = 0.35-0.95) reduction in claims. CONCLUSIONS: These findings provide evidence of the effectiveness of safety and health training in preventing occupational injuries among construction laborers, particularly among younger workers. However, the results cover only a limited time and the long-term effects remain unclear.

Comparative in vitro pediculicidal efficacy of treatments in a resistant head lice population in the United States.

OBJECTIVE: To compare the pediculicidal activity of 5 head lice products available in the United States on head lice from south Florida. DESIGN: In vitro pediculicidal product comparison. SETTING: Lice Source Services, Inc, located in Plantation, Fla, a clinic for the treatment and grooming of individuals with pediculosis capitis. PARTICIPANTS: Head lice were collected from healthy clients with Pediculus capitis that came to Lice Source Services, Inc, to seek their services. INTERVENTIONS: Within 2 to 6 hours of capture, lice were placed in continuous direct contact with the pediculicide products and observed at regular intervals. Results were compared with findings of a recent study of a treatment-sensitive population of head lice conducted in Panama. MAIN OUTCOME MEASURE: Percentage of lice dead at regular observation intervals between 5 minutes and 3 hours of continuous exposure to the pediculicides. RESULTS: Two prescription products, Ovide lotion (0.5% malathion) and 1% lindane shampoo, were ranked in the same order as in 2 previous studies (first and last, respectively). The order of effectiveness from most to least effective was as follows: Ovide lotion, A-200 shampoo (a natural pyrethrin product synergized with piperonyl butoxide), undiluted Nix (1% permethrin), diluted Nix, RID (a natural pyrethrin product synergized with piperonyl butoxide), and 1% lindane shampoo. CONCLUSIONS: There were statistically significant differences in the efficacy of all the products when compared with the results found in the recent study in Panama, except for Ovide lotion. Of those tested, Ovide was the only pediculicide in the United States that had not become less effective. The difference in efficacy of 1% lindane, Nix, and pyrethrins between the Panama and Florida studies supports the argument that some head lice in the United States have become resistant to these treatments.
