Capacity management of nursing staff as a vehicle for organizational improvement

<p>Abstract</p> <p>Background</p> <p>Capacity management systems create insight into required resources like staff and equipment. For inpatient hospital care, capacity management requires information on beds and nursing staff capacity, on a daily as well as annual basis. This paper presents a comprehensive capacity model that gives insight into required nursing staff capacity and opportunities to improve capacity utilization on a ward level.</p> <p>Methods</p> <p>A capacity model was developed to calculate required nursing staff capacity. The model used historical bed utilization, nurse-patient ratios, and parameters concerning contract hours to calculate beds and nursing staff needed per shift and the number of nurses needed on an annual basis in a ward. The model was applied to three different capacity management problems on three separate groups of hospital wards. The problems entailed operational, tactical, and strategic management issues: optimizing working processes on pediatric wards, predicting the consequences of reducing length of stay on nursing staff required on a cardiology ward, and calculating the nursing staff consequences of merging two internal medicine wards.</p> <p>Results</p> <p>It was possible to build a model based on easily available data that calculate the nursing staff capacity needed daily and annually and that accommodate organizational improvements. Organizational improvement processes were initiated in three different groups of wards. For two pediatric wards, the most important improvements were found to be improving working processes so that the agreed nurse-patient ratios could be attained. In the second case, for a cardiology ward, what-if analyses with the model showed that workload could be substantially lowered by reducing length of stay. The third case demonstrated the possible savings in capacity that could be achieved by merging two small internal medicine wards.</p> <p>Conclusion</p> <p>A comprehensive capacity model was developed and successfully applied to support capacity decisions on operational, tactical, and strategic levels. It appeared to be a useful tool for supporting discussions between wards and hospital management by giving objective and quantitative insight into staff and bed requirements. Moreover, the model was applied to initiate organizational improvements, which resulted in more efficient capacity utilization.</p

Printing of complex free-standing microstructures via laser-induced forward transfer (LIFT) of pure metal thin films

A combined approach of laser-induced forward transfer (LIFT) and chemical etching of pure metal films is studied to fabricate complex, free-standing, 3-dimensional gold structures on the few micron scale. A picosecond pulsed laser source with 515 nm central wavelength is used to deposit metal droplets of copper and gold in a sequential fashion. After transfer, chemical etching in ferric chloride completely removes the mechanical Cu support leaving a final free-standing gold structure. Unprecedented feature sizes of smaller than 10 μm are achieved with surface roughness of 0.3 to 0.7 μm. Formation of interfacial mixing volumes between the two metals is not found confirming the viability of the approach

Correlation and Relative Prognostic Value of Fractional Flow Reserve and Pd/Pa of Nonculprit Lesions in ST-Segment-Elevation Myocardial Infarction

BACKGROUND: The applicability of resting indices to guide noninfarct-related artery revascularization in ST-elevation myocardial infarction is unknown. METHODS: We analyzed the correlation and prognostic value of fractional flow reserve (FFR) and resting distal coronary to aortic pressure ratio (Pd/Pa) in all patients of the Compare-Acute trial in whom, after successful primary percutaneous coronary intervention, the noninfarct-related artery was interrogated by both and treated medically. The treating cardiologist was blinded to these values. The primary end point was the composite of target vessel (interrogated noninfarct-related artery) related nonfatal target vessel myocardial infarction and target vessel repeat revascularization at 36 months. RESULTS: Five hundred seventeen patients (665 vessels) were included. On receiver-operating characteristic analysis, the optimal Pd/Pa cut off for FFR≤0.80 was 0.905 (C statistic: 0.894). The diagnostic accuracy of Pd/Pa was 80.15% (95% CI, 76.91%-83.12%) with respect to FFR. During the 36-month follow-up, 130 target vessel revascularization and 14 target vessel myocardial infarction occurred. FFR and Pd/Pa had a diagnostic accuracy to predict these events of 62.86% (95% CI, 59.06%-66.54%) and 56.84% (95% CI, 52.98%-60.64%), respectively (P=0.20). When they were discrepant, FFR was significantly better than Pd/Pa in identifying which vessels could be safely deferred (P=0.048). CONCLUSIONS: Immediately after successful primary percutaneous coronary intervention, resting Pd/Pa has a diagnostic accuracy of 80% with respect to FFR measured in the noninfarct-related artery. FFR is not significantly superior in predicting target vessel myocardial infarction and target vessel revascularization during 36 months of follow-up but, in case FFR and Pd/Pa are discrepant, FFR is superior in identifying which nonculprit vessels can be safely deferred.

The Natural History of Nonculprit Lesions in STEMI: An FFR Substudy of the Compare-Acute Trial

Objectives: The aim of this study was to determine the prognostic value of fractional flow reserve (FFR) in non-infarct-related arteries (IRAs) in ST-segment elevation myocardial infarction (MI). Background: Patients with ST-segment elevation MI often present with multivessel disease. The treatment of non-IRAs is debated. The applicability of FFR has not been widely proved. Methods: Outcomes were analyzed in all patients in the Compare-Acute (Comparison Between FFR Guided Revascularization Versus Conventional Strategy in Acute STEMI Patients With MVD) trial in whom, after successful primary percutaneous coronary intervention, non-IRAs were interrogated using FFR and treated medically. The treating cardiologist was blinded to the FFR value. The primary endpoint was the composite of cardiovascular mortality, target vessel–related (non-IRA with FFR measurement at primary percutaneous coronary intervention) nonfatal MI, and target vessel revascularization: major adverse cardiac events (MACE) at 24 months. Results: A total of 751 patients (963 vessels) were included. Target non-IRAs with MACE had lower FFR compared with those without (0.78 vs. 0.84, respectively; p < 0.001). The median FFR of non-IRAs with TVR was lower than that of those without (0.79 vs. 0.85, respectively; p < 0.001). The difference was significant in all vessels. The median FFR of target non-IRAs with MI was lower than that of those without (0.79 vs. 0.84, respectively; p = 0.016). The MACE rate was significantly (p < 0.001) higher in the lowest of FFR tertiles (<0.80) compared with the others (0.80 to 0.87 and ≥0.88). Conclusions: In patients with ST-segment elevation MI with multivessel disease, FFR measured in the medically treated non-IRA immediately after successful primary percutaneous coronary intervention shows a nonlinear and inverse risk continuum of MACE. Importantly, worsening prognosis is demonstrated around the cutoff of 0.80

Long-term safety of adalimumab in clinical trials in adult patients with Crohn's disease or ulcerative colitis

BACKGROUND: Adalimumab is used to treat moderate to severe Crohn's disease (CD) and ulcerative colitis (UC) when conventional therapies fail. AIM: To update long-term adalimumab safety from CD and UC trials; the previous report was CD only, 3160 patients/3402 patient-years (PYs). METHODS: Treatment-emergent adverse events (AEs; first dose to 70 days after last dose/December 31, 2015) in adults in phase 2/3 and 3/3b trials and open-label extensions were coded using Medical Dictionary for Regulatory Activities (MedDRA-v18.1). Rates were assessed as events/100 (E/100 PYs). RESULTS: The database (16 trials; CD, N = 3606; UC, N = 1739) represented 4145 and 3397 PYs of exposure, respectively. For CD, incidences of any AEs with adalimumab were 60.8%-65.1%, depending on dose, and 71.5% with placebo; for UC, the incidences were 53.5%-54.8% and 56.1%, respectively. Rates of any AEs (CD, 605 E/100 PYs; UC, 361 E/100 PYs), serious AEs (CD, 36.1 E/100 PYs; UC, 18.9 E/100 PYs), and malignancies (CD, 1.2 E/100 PYs; UC, 1.0 E/100 PYs) were similar between current and prior analyses. Apparent rate of opportunistic infections was lowered to 0.3 and 0.2 E/100 PYs for CD and UC, respectively, by recent MedDRA changes excluding oral candidiasis and tuberculosis. Standardised incidence ratios for malignancies were similar to the general population (CD, 1.45 [95% CI, 0.90-2.22]; UC, 1.36 [95% CI, 0.84-2.07]). Demyelinating disorders were uncommon (CD, 0.1 E/100 PYs; UC, <0.1 E/100 PYs). CONCLUSIONS: Patients with moderately to severely active Crohn's disease or ulcerative colitis continued to experience acceptable safety with adalimumab, without new safety signals.status: publishe

Rationale and design of the future optimal research and care evaluation in patients with acute coronary syndrome (Force-acs) registry: Towards “personalized medicine” in daily clinical practice

Diagnostic and treatment strategies for acute coronary syndrome have improved dramatically over the past few decades, but mortality and recurrent myocardial infarction rates remain high. An aging population with increasing co-morbidities heralds new clinical challenges. Therefore, in order to evaluate and improve current treatment strategies, detailed information on clinical presentation, treatment and follow-up in real-world patients is needed. The Future Optimal Research and Care Evaluation in patients with Acute Coronary Syndrome (FORCE-ACS) registry (ClinicalTrials.gov Identifier: NCT03823547) is a multi-center, prospective real-world registry of patients admitted with (suspected) acute coronary syndrome. Both non-interventional and interventional cardiac centers in different regions of the Netherlands are currently participating. Patients are treated according to local protocols, enabling the evaluation of different diagnostic and treatment strategies used in daily practice. Data collection is performed using electronic medical records and quality-of-life questionnaires, which are sent 1, 12, 24 and 36 months after initial admission. Major end points are all-cause mortality, myocardial infarction, stent thrombosis, stroke, revascularization and all bleeding requiring medical attention. Invasive therapy, antithrombotic therapy including patient-tailored strategies, such as the use of risk scores, pharmacogenetic guided antiplatelet therapy and patient reported outcome measures are monitored. The FORCE-ACS registry provides insight into numerous aspects of the (quality of) care for acute coronary syndrome patients

Mindfulness-based cognitive therapy for patients with medically unexplained symptoms: A cost-effectiveness study

Item does not contain fulltextOBJECTIVE: Our aim was to assess cost-effectiveness of mindfulness-based cognitive therapy (MBCT) compared with enhanced usual care (EUC) in treating patients with persistent medically unexplained symptoms(MUS). METHODS: A full economic evaluation with a one year time horizon was performed from a societal perspective. Costs were assessed by prospective cost diaries. Health-related Quality of Life was measured using SF-6D. Outcomes were costs per Quality-Adjusted Life Year (QALY). Bootstrap simulations were performed to obtain mean costs, QALY scores and incremental cost-effectiveness ratios (ICERs). RESULTS: MBCT participants (n=55) had lower hospital costs and higher mental health care costs than patients who received EUC (n=41). Mean bootstrapped costs for MBCT were euro6269, and euro5617 for EUC (95% uncertainty interval for difference: -euro1576; euro2955). QALYs were 0.674 for MBCT and 0.663 for EUC. MBCT was on average more effective and more costly than EUC, resulting in an ICER of euro56,637 per QALY gained. At a willingness to pay of euro80,000 per QALY, the probability that MBCT is cost-effective is 57%. CONCLUSION: Total costs were not statistically significantly different between MBCT and EUC. However, MBCT seemed to cause a shift in the use of health care resources as mental health care costs were higher and hospital care costs lower in the MBCT condition. Due to the higher drop-out in the EUC condition the cost-effectiveness of MBCT might have been underestimated. The shift in health care use might lead to more effective care for patients with persistent MUS. The longer-term impact of MBCT for patients with persistent MUS needs to be further studied
