Generalized Indicator

When designing power facilities, the problem usually arises of comparing their possible options for performance, taking into account consumer quality. A common and easy-to-implement method is the formation of a generalized indicator, however, subjectivity is inherent in it, given this, the task of developing algorithms and methods that objectively consider the quality indicators of an energy object becomes especially urgent. It is argued that, in accordance with the condition for making a decision on the type of the synthesizing function, the main object of uncertainty, respectively, of the quality indicator, which is inherently subjective, is the vector of the significance coefficients of the weight coefficients. The presented algorithms in conditions of uncertainty that allow you to build a generalized quality criterion for energy facilities. For a comprehensive assessment of the quality of energy facilities, it is proposed to use the methods of arbitrary summary indicators, namely: the method of arbitrary summary indicators, the method of priority of private quality indicators and the method of minimizing the deviation of the summary quality indicator. It is proposed to reduce the influence of subjective factors in determining the weight coefficients, it is advisable to use a combination of these methods. For the method of minimizing the deviation of the aggregate indicator, using the principle of objectivity, an algorithm for determining the weight coefficients has been developed, taking into account that in the area of permissible changes in parameters, the value of the criterion will be minimal. Accordingly, to solve the problem of comparing the options for constructing energy facilities, which includes the determination of weight coefficients for the formation of a composite indicator, it is necessary to use the results of expert assessment that are supplemented by calculation methods that will reduce the subjective factor that is inherent in the method of expert assessment.

Care Evaluation

Funnel plots are graphical tools to assess and compare clinical performance of a group of care professionals or care institutions on a quality indicator against a benchmark. Incorrect construction of funnel plots may lead to erroneous assessment and incorrect decisions potentially with severe consequences. We provide workflow-based guidance for data analysts on constructing funnel plots for the evaluation of binary quality indicators, expressed as proportions, risk-adjusted rates or standardised rates. Our guidelines assume the following steps: (1) defining policy level input; (2) checking the quality of models used for case-mix correction; (3) examining whether the number of observations per hospital is sufficient; (4) testing for overdispersion of the values of the quality indicator; (5) testing whether the values of quality indicators are associated with institutional characteristics; and (6) specifying how the funnel plot should be constructed. We illustrate our guidelines using data from the Dutch National Intensive Care Evaluation registry. We expect that our guidelines will be useful to data analysts preparing funnel plots and to registries, or other organisations publishing quality indicators. This is particularly true if these people and organisations wish to use standard operating procedures when constructing funnel plots, perhaps to comply with the demands of certification.

We conducted a systematic review of clinical guidelines (CGs) to examine the methodological approaches of quality indicator derivation in CGs, the frequency of quality indicators to check CG recommendations in routine care, and clinimetric properties of quality indicators. We analyzed the publicly available CG databases of the Association of the Scientific Medical Societies in Germany (AWMF) and National Institute for Health and Care Excellence (NICE). Data on the methodology of subsequent quality indicator derivation, the content and definition of recommended quality indicators, and clinimetric properties of measurement instruments were extracted. In Germany, no explicit methodological guidance exists, but 3 different approaches are used. For NICE, a general approach is used for the derivation of quality indicators out of quality standards. Quality indicators were defined in 34 out of 87 CGs (39%) in Germany and for 58 out of 133 (43%) NICE CGs. Statements regarding measurement properties of instruments for quality indicator assessment were missing in German and NICE documents. Thirteen pairs of CGs (32%) have associated quality indicators. Thirty-four quality indicators refer to the same aspect of the quality of care, which corresponds to 27% of the German and 7% of NICE quality indicators. The development of a standardized and internationally accepted methodology for the derivation of quality indicators relevant to CGs is needed to measure and compare quality of care in health care systems.

<p><strong>ABSTRACT</strong></p><p><strong>Background: </strong>Medication reconciliation at transitions of care increases patient safety. Collection of an accurate best possible medication history (BPMH) on admission is a key step. National quality indicators are used as surrogate markers for BPMH quality, but no literature on their accuracy exists. Obtaining a high-quality BPMH is often labour- and resource intensive. Pharmacy students are now being assigned to obtain BPMHs, as a cost-effective means to increase BPMH completion, despite limited information to support the quality of BPMHs obtained by students relative to other health care professionals.</p><p><strong>Objectives: </strong>To determine whether the national quality indicator of using more than one source to complete a BPMH is a true marker of quality and to assess whether BPMHs obtained by pharmacy students were of quality equal to those obtained by nurses.</p><p><strong>Methods: </strong>This prospective trial compared BPMHs for the same group of patients collected by nurses and by trained pharmacy students in the emergency departments of 2 sites within a large health network over a 2-month period (July and August 2016). Discrepancies between the 2 versions were identified by a pharmacist, who determined which party (nurse, pharmacy student, or both) had made an error. A panel of experts reviewed the errors and ranked their severity.</p><p><strong>Results: </strong>BPMHs were prepared for a total of 40 patients. Those prepared by nurses were more likely to contain an error than those prepared by pharmacy students (171 versus 43 errors, <em>p </em>= 0.006). There was a nonsignificant trend toward less severe errors in BPMHs completed by pharmacy students. There was no significant difference in the mean number of errors in relation to the specified quality indicator (mean of 2.7 errors for BPMHs prepared from 1 source versus 4.8 errors for BPMHs prepared from ≥ 2 sources, <em>p </em>= 0.08).</p><p><strong>Conclusions: </strong>The surrogate marker (number of BPMH sources) may not reflect BPMH quality. However, it appears that BPMHs prepared by pharmacy students had fewer errors and were of similar quality (in terms of clinically significant errors) relative to those prepared by nurses.</p><p><strong>RÉSUMÉ</strong></p><p><strong>Contexte : </strong>L’établissement du bilan comparatif des médicaments au moment du transfert des soins accroît la sécurité des patients. L’obtention d’un meilleur schéma thérapeutique possible (MSTP) exact à l’admission en est une étape clé. Des indicateurs nationaux de la qualité sont utilizes comme critères de substitution pour évaluer la qualité des MSTP, mais il n’y a pas de documentation se penchant sur leur exactitude. Obtenir un MSTP de grande qualité est souvent exigeant sur le plan du personnel et des ressources. Des étudiants en pharmacie se voient maintenant confier l’élaboration de MSTP, une façon peu coûteuse d’accroître les taux de réalisation de MSTP; or, il n’y a que peu d’information pour valider le degré de qualité des MSTP obtenus par des étudiants en comparaison avec ceux produits par d’autres professionnels de la santé.</p><p><strong>Objectifs : </strong>Déterminer si l’indicateur national de qualité basé sur le recours à plus d’une source de renseignements pour réaliser un MSTP est un vrai marqueur de qualité et évaluer la qualité relative des MSTP de la part des étudiants en pharmacie et du personnel infirmier.</p><p><strong>Méthodes : </strong>Dans la présente étude prospective réalisée sur une période de deux mois (en juillet et en août 2016), les chercheurs ont comparé les MSTP recueillis auprès du même groupe de patients par du personnel infirmier et par des étudiants en pharmacie qualifiés dans les services des urgences de deux établissements faisant partie d’un important réseau de santé. Un pharmacien relevait les divergences entre les deux versions du MSTP et imputait l’erreur soit au personnel infirmier, soit à l’étudiant en pharmacie ou soit aux deux parties. Un groupe d’experts a étudié les erreurs et leur a accordé une cote selon leur degré de gravité.</p><p><strong>Résultats : </strong>Des MSTP ont été réalisés auprès de 40 patients. Ceux préparés par le personnel infirmier étaient plus susceptibles de contenir une erreur que ceux établis par les étudiants en pharmacie (171 contre 43 erreurs, <em>p </em>= 0,006). On a noté une tendance non significative selon laquelle les erreurs commises par les étudiants en pharmacie étaient moins graves. Aucune différence significative n’a été relevée quant au nombre moyen d’erreurs par rapport à l’indicateur de qualité (2,7 pour les MSTP provenant d’une source contre 4,8 pour les MSTP provenant de deux sources ou plus, <em>p </em>= 0,08).</p><p><strong>Conclusions : </strong>Le critère de substitution (nombre de sources pour le MSTP) pourrait ne pas être représentatif de la qualité du MSTP. Cependant, il semble que les MSTP préparés par les étudiants en pharmacie comportaient moins d’erreurs et étaient de qualité comparable (quant aux erreurs cliniquement significatives) à ceux établis par le personnel infirmier.</p>

The aim of the research is to study the effect of protein-containing ingredients of animal and plant origin on the quality indicators of yoghurt for the scientific substantiation of its recipe composition. Micellar casein and spelled flour are characterized by high nutritional value, exhibit functional and technological properties and can significantly affect the quality indicators of yogurt. To confirm this, the possibility of complete replacement of the structure stabilizer in the composition of yoghurt with micellar casein and spelled flour, both separately and in various ratios, was studied. As a single criterion for optimizing the recipe composition of yoghurt at various ratios between casein and spelled flour, product quality indicators were used: the degree of syneresis, effective viscosity, organoleptic indicators. The optimal values of the single criteria were obtained at different ranges of ratios between natural ingredients, which don’t allow developing uniform recommendations for the formulation of a new type of yogurt. Therefore, to study the combined effect of protein and spelled flour on the characteristics of yoghurt and the coefficients of their significance, a complex quality indicator was used. This indicator was determined as a function of estimates of single quality indicators, converted to scaled values, taking into account the coefficients of significance of individual indicators. Using a complex quality indicator, the ranges of optimal values of the content of micellar casein and spelled flour in yoghurt were established. So, when adding casein in an amount of 1.25 to 3.0 % and spelled flour - from 0.75 to 1.50 %, the quality of yoghurt reached its maximum value. The use of these ingredients alone showed a significantly lower technological effect in comparison with their compositions. Therefore, a conclusion was made about the synergistic interaction of casein and spelled flour, as well as the advisability of using the compositional composition of these ingredients in the yogurt technology

Background: Although a number of quality indicators for palliative care have been implemented worldwide, evidence regarding the performance of palliative care teams is scarce. Aim: Evaluating the quality of palliative care using quality indicators; to describe the variation in quality between palliative care teams; and to suggest quality benchmarks for these teams. Design: A repeated cross-sectional study design to collect quality indicator data by means of a validated quality indicator set in 36 Belgian palliative care teams at home and in hospitals. Risk-adjustment procedures, taking into account patient-mix, were applied to suggest benchmarks. Participants: Between 2014 and 2017, five quality measurements with questionnaires were conducted in 982 patients receiving palliative care, 4701 care providers and 1039 family members of deceased patients. Results: A total of 7622 assessments were received. Large risk-adjusted variations between the different palliative care teams were identified in: regularly updating patient files (IQR: 12%–39%), having multidisciplinary consultations about care objectives (IQR: 51%–73%), discussing end-of-life care decisions with patients (IQR: 26%–71%–92%), relieving shortness of breath (IQR: 57%–78%), regularly assessing pain (IQR: 43%–74%) and symptoms by means of validated scales (IQR: 23%–60%), initiating palliative care at least 2 weeks before death (IQR: 30%–50%), and weekly contact with the GP in the last 3 months of life (IQR 16%–43%). Conclusion: The large risk-adjusted variation found across the quality indicator scores suggest that repeated and standardized quality improvement evaluations can allow teams to benchmark themselves to each other to identify areas of their palliative care delivery that need improvement.

Background. A comprehensive commodity evaluation of the developed motor fuels with the use of biocomponents with the use of expert evaluation was carried out. The advantages in terms of operational and ecological properties over the basic analogues of A-95 gasoline and L-grade diesel fuel of domestic production are proved. The economic efficiency of the developed fuel compositions is proved and substantiated. Materials and methods. The object of research is motor fuels with biocom­ponents. The subject of research – operational and environmental properties of motor fuels with bio­components. A-95 gasoline and L-grade diesel fuel manufactured by PJSC Ukrtatnafta were identified as basic samples. Calculation and expert methods were used in conducting a comprehensive assess­ment of the quality of motor fuels. The complex quality indicator of the developed A-95 gasoline with biocompo­nents was determined on the basis of operational and ecological properties according to the follo­wing indicators: octane number; fractional composition; density; corrosion on a copper plate; sulfur content; volume fraction of aromatic hydrocarbons; volume fraction of benzene. A group of qualified experts was involved to establish the ranks of quality indicators. Results. Experts assessed the importance of selected indicators to assess the level of quality by ranking them. The comprehensive quality indicator is calculated on the basis of experimental and baseline values of performance and environmental performance indicators to deter­mine the consumer benefits of developed fuels with biocomponents over baseline. As a result of the calculations, it was determined that the complex quality indi­cator of the proposed fuels Q> 1, which indicates a higher level of quality compared to the basic fuel samples. Conclusion. It is established that the complex quality indicators of the developed fuels are for gasoline A-95 with biocomponents – 1.17, and for B L brand with biocom­ponents – 2.04, which indicates the qualitative advantages of the latter compared to ana­logues. Thus, in general, comprehensive indicators of the quality of performance of deve­loped fuels with biocomponents prove the feasibility of their production and use in vehicles.
