RESUMO

BACKGROUND: The creation of a patient blood management (PBM) certification program by The Joint Commission (TJC) and Association for the Advancement of Blood and Biotherapies (AABB) provides validation of an existing PBM program. MATERIALS AND METHODS: A team of subject matter experts in PBM formed a working group to develop a structured approach to guide PBM programs through the PBM certification. Program challenges and metrics were reviewed. RESULTS: Initial steps to establishing PBM certification include a multidisciplinary working group and hospital administration buy-in. Development of policies and procedures individualized to the facility will standardize practice. An institutional transfusion committee can provide PBM oversight including enforcing compliance. Using resources such as TJC and AABB standards and tools including electronic medical records (EMR) can track and trend hospital PBM performance and identify improvement opportunities. A gap analysis tool helps implementation. Challenges might include maintaining a PBM program during a merger, slow responsiveness of information systems (IS) to requests, PBM education for both the Transfusion Safety Officer (TSO) and hospital staff with constant turnover. Available metrics from one hospital system showed good compliance with transfusion thresholds (average all products: 97.9%, 2019, 2020). In 2020, through educational efforts the cost savings were $124,856.70 compared to 2019. Regarding single unit transfusion of RBCs, this was 62.25% (2019), 63.75% (2020), 72.00% (2021), and surpassed the target goal of 60%. CONCLUSIONS: Obtaining PBM certification highlights the success of an institution's PBM program. Facilities that have achieved PBM certification have seen significant reductions in transfusions and considerable cost savings.

RESUMO

Assessment of arterio-venous fistula (AVF) blood flow (ABF) is vital in hemodialysis (HD) patients. Currently, no non-invasive and contact-free technique is available to accurately measure ABF in routine clinical practice. In this study, we developed a novel approach using video image processing (VIP) to measure the change in optic flow in the skin. We the tested the hypothesis that the change in optical flow, expressed as the change in pixels between consecutive frames, is related to ABF. We recorded AVF videos in 40 HD patients using a digital camera and processed them by VIP technique. We then compared the actual ABF as measured by routine online clearance (ABFOLC) and the amplitude (AMP) of optical flow. Technical and procedural errors rendered VIP invalid in 13 patients. In the remaining 27 patients the optical flow AMP was significantly lower in patients with low (<;900 ml/min) ABFOLC compared to patients with normal (≥900 ml/min) ABFOLC (AMP 3.4±1*103 vs 5.2±1.4 *103 [pixels], p<;0.01). In these 27 patients AMP correlated with ABFOLC (R2=0.71, p<;0.0001). While more extensive research is necessary, these preliminary results indicate the potential usefulness of the VIP technique to identify low ABF.

RESUMO

BACKGROUND: Anorexia nervosa is a psychiatric disorder characterized by restrictive eating, low body weight, and severe bone loss. Recent data show a deleterious relationship between low circulating sodium levels and bone mass, and relative or absolute hyponatremia is a known complication of anorexia nervosa. Clinical studies of other medical conditions associated with hyponatremia suggest that detrimental effects of low sodium levels on health are seen even within the normal range. We hypothesized that women with anorexia nervosa and relatively low plasma sodium levels would have lower bone mineral density (BMD) than those with higher plasma sodium levels. METHOD: In a cross-sectional study (January 1, 1997-December 31, 2009) of 404 women aged 17 to 54 years (mean ± standard error of the mean [SEM] age = 25.6 ± 0.3 years) who met DSM-IV criteria for anorexia nervosa, we measured BMD using dual-energy x-ray absorptiometry. Bone mineral density was compared in women with plasma sodium levels < 140 mmol/L (midpoint of normal range) versus those with plasma sodium levels ≥ 140 mmol/L and in women with hyponatremia (plasma sodium < 135 mmol/L) versus those without. The study was conducted at the Neuroendocrine Unit of Massachusetts General Hospital, Boston. RESULTS: Women with plasma sodium levels < 140 mmol/L had significantly lower BMD and t and z scores versus those with plasma sodium levels ≥ 140 mmol/L at the anterior-posterior (AP) spine (mean ± SEM z scores = -1.6 ± 0.1 vs -1.3 ± 0.1, P = .004) and total hip (mean ± SEM z scores = -1.2 ± 0.1 vs -0.9 ± 0.1, P = .029). In a model controlling for age, BMI, psychiatric drug use, and disease duration, differences in BMD and t and z scores remained significant at the AP spine. Women with hyponatremia had significantly lower BMD and t and z scores versus those without hyponatremia at the AP spine (mean ± SEM z scores = -2.2 ± 0.3 vs -1.3 ± 0.1, P = .009), lateral spine (mean ± SEM z scores = -2.4 ± 0.4 vs -1.5 ± 0.1, P = .031), and total hip (mean ± SEM z scores = -2.5 ± 0.5 vs -1.0 ± 0.1, P < .0001). In a model controlling for age, BMI, psychiatric drug use, and disease duration, differences in BMD and z and t scores remained significant at all sites. CONCLUSIONS: These data suggest that relative plasma sodium deficiency may contribute to anorexia nervosa-related osteopenia.
