Evaluation of Causes and Rate of Wastage of Blood and its Components – An Important Quality Indicator in Blood Banks.

Background: The evaluation of wastage of blood products represents an important element in the appropriate use of blood components, a critical control point in the system of blood administration. Discarding or wastage of blood can be attributed to several reasons namely time expiry, wasted import, non-usage of ordered blood, broken bags and seal with leakage, hemolytic reasons, clotted blood, returned after 30 min, and miscellaneous others.Wasting of blood and blood components are an inefficient use of resources and may be avoided. The present study was undertaken with aim of primarily to determine the frequency of blood products wasting and secondarily to determine the factors that affect blood products wastage at our institute. Methods: The present study is a retrospective cross sectional descriptive study conducted in a tertiary teaching hospital located in South Delhi catering to low socioeconomic population. Blood component wastage was defined as components that did not meet the required standards of hospitals or fractionation centres during collection, processing and storage. The main reasons included expiry date, inappropriate volume, haemolysis of red blood cells (RBCs), contamination of plasma or platelets with RBCs, blood bag leakage, reactive infectious disease tests and inappropriate temperature during storage or transportation. The required data from clinical units and blood bank were collected and analyzed for a period of 7 years. Results: A total of 13728 blood units were received during the specified period. Overall wasted factor was of 18.5% with maximum wastage of platelet concentrate units (53.7%). Analyzing the causes of blood and blood product wastage in the hospital for this study showed that blood and blood product wastage were associated with many causes of which the common causes, included the expiration of the usability period (69.2%), sero-reactivity for infectious diseases (13.7%) and Quality Control units (9.2%). Conclusion: Blood is an irreplaceable precious resource which needs to be properly utilized with minimal wastage. Although present study was limited due to its retrospective nature but it still outlines the importance to emphasize that measures should be taken into account for formulating guidelines, effective policies, and training efforts for personnel.

Evaluation of the Validity of Vial Sizes for the Efficient Use of Tocilizumab Formulations / 医薬品情報学

Objective: Tocilizumab and infliximab are biologic drugs that are widely used for the treatment of rheumatoid arthritis (RA). The dosage of these injectable RA drugs is calculated based on body weight. However, injectable RA drugs are used only once due to stability and sterility concerns. For expensive biologic drugs, drug disposal wastage needs to be reduced. Tocilizumab is approved in three vial sizes: 80, 200, and 400 mg. In this study, we evaluated the validity of these tocilizumab vial sizes to help resolve the issue of excess residual drug.Methods: A log-normal distribution was assumed for body weight, and 10,000 hypothetical cases were created using the programming language R. We analyzed the average wasted dose rate per vial (%) by gender after considering different vial size combinations.Results: The average wasted dose rate per vial of tocilizumab was estimated to be 3.7% for males and 4.7% for females.Conclusion: The three vial sizes of 80, 200, and 400 mg are reasonable for tocilizumab. The average wasted dose rate per vial of infliximab was estimated to be 17.7% for males and 22.6% for females. The average wasted dose rate per vial was lower for tocilizumab than infliximab. Tocilizumab is administered in a dose range of 200 to 1,100 mg with three different vial sizes in multiples of 40 mg. However, infliximab is administered in a dose range of 50 to 400 mg with a single vial size of 100 mg. Multiple vial sizes should be prepared to ensure the efficient use of limited medical resources. It is also expected that the method employed for this hypothetical case model will be applied to other drugs for which disposal wastage is a problem and used to set appropriate vial size combinations.

Oxygen as a drug and scarce commodity: Do we use it rationally?

Medical grade oxygen is classified as a drug and needs to be prescribed by a qualified healthcare professional. Oxygen therapy is prescribed to people who cannot maintain normal blood oxygen saturation while breathing atmospheric air. The coronavirus disease 2019 (COVID-19) pandemic highlighted the importance of the rational use of this scarce commodity. This study investigated oxygen therapy practices in adult ward patients. Methods: A cross-sectional study design with an analytical component was used in the adults' wards at a National District Hospital and the Pelonomi Academic Hospital in Bloemfontein. Data were collected from patient files, interviews and oxygen measurements of adult patients that received oxygen. Results: One hundred and fifteen patients were included in the study, of whom 47.0% received oxygen without an oxygen prescription. Around 62.3% of the patients with prescriptions did not receive oxygen as prescribed. The prescriptions and oxygen administration for COVID-19 patients were better than for non­COVID-19 patients. A quarter of the patients possibly received oxygen therapy unnecessarily. Conclusion: Poor oxygen therapy practices were identified, including prescription errors, oxygen administration errors and oxygen wastage. A protocol should be developed and implemented for the prescription and administration of oxygen therapy. Training should occur to prevent oxygen wastage. Contribution: This study highlighted poor oxygen practices and prescriptions, as well as oxygen wastage in the absence of local oxygen therapy guidelines.

Re-exposure animal bite management among incident animal bite cases in a secondary care Hospital in Delhi, India

Complete postexposure prophylaxis with 4 doses of anti-rabies vaccine (ARV) in a previously vaccinated (nonna飗e) individual results in administration of two extra ARV doses resulting in wastages of precious resources comprising vaccine logistics, human resources, physician, and patient time. This cross-sectional study conducted in a secondary care hospital in Delhi among 175 incident animal bite cases observed 39 (22.3%) had an animal-bite history within the previous 5 years. A total of 19 (10.8%) cases reported a history of complete ARV vaccination during a previous animal-bite exposure. However, in the absence of supportive patient medical documentation, all the animal bite cases without exception were prescribed a full course of ARV irrespective of their previous exposure status. Rabies immunoglobulins (anti rabies serum) were also re-administered in 13 (81.2%) cases. National guidelines for rabies prophylaxis should, therefore, consider the inclusion of an explicit decision-making algorithmic mechanism when the health-care provider is confronted with this situation carrying the potential for hidden vaccine wastage.

Assessment of vaccine wastage in an immunization clinic of a tertiary care hospital, Kolkata, West Bengal

Background: Universal Immunization Programme was launched by Government of India in 1985 with the aim of immunizing all children and pregnant women across the country free of cost. However high vaccine wastage and lack of proper vaccine management could not meet the demand and increased the cost.Methods: A descriptive record based study was conducted in the immunization clinic of KPC Medical College and Hospital. Vaccination records of all children and pregnant women attending clinic from 1st July 2018 to 30th June 2019 was retrieved from the immunization registers.Results: Wastage rate was found to be highest for bacillus Calmette–Guérin vaccine vaccine (68.9%) and lowest for oral polio vaccine (27.7%). Wastage rate was higher for 10 dose vial vaccine compared to 5 dose vial and 20 dose vial vaccine and the differences were statistically significant (p<0.00001).The wastage rate was higher for lyophilized vaccine compared to liquid vaccine and for injectable vaccine compared to oral vaccine. These differences were also statistically significant (p<0.00001).Conclusions: Thus regular monitoring of immunization sessions should be done to estimate the vaccine wastage in each session. Reducing wastage is expected to increase the quality and efficiency of the programme and also reduce the cost without compromising the coverage.

Plate Wastage Among Hospitalized Cancer Patients

@#Introduction: Plate wastage in hospital contributes to malnutrition-related complications including longer hospitalization among cancer patients. The objective of this study was to determine the relationship between patients’ experiences of access to food hospital and plate wastage among hospitalized cancer patients. Methods: Two hundred and thirty-one cancer patients in the National Cancer Institute, Malaysia were recruited for this study. All eligible patients were undergoing cancer treatments and provided with informed consent. Data obtained included socio-demographic characteristics and patients’ experiences of access to food hospital which will contribute to plate wastage. Plate wastage was determined by weighing the unwanted food left on the plate. Results: Prevalence of plate wastage among cancer patients was high at approximately 54%. The appearance of food served was associated with higher plate wastage (p<0.01). Conclusion: This finding shows that the prevalence of plate wastage was high which may inhibit food consumption and affecting nutritional status among cancer patients with oncologic treatment. Effective strategies that address factors associated with plate wastage should be taken among hospitalized cancer patients

O objetivo deste estudo foi avaliar a adequação nutricional das refeições servidas e consumidas e quantificar o desperdício de alimentos em Centros de Educação Infantil de Maceió/AL. Foram analisadas por três dias não consecutivos, pelo método de pesagem direta, as refeições de 359 crianças (17 e 63 meses). O desperdício de alimentos foi determinado pelo índice de resto-ingestão e o valor nutricional das refeições servidas e consumidas foram comparadas com os valores de referência do PNAE para energia, carboidrato, proteína, lipídio, vitaminas A e C, ferro, cálcio, zinco, magnésio e fibra. Dos 85 alimentos/preparações presentes no cardápio, 58 (68%) apresentaram percentual de resto-ingestão, superior a 10%. As refeições servidas e consumidas atenderam aproximadamente 50% do recomendado para energia e macronutrientes. A diferença entre as médias dos nutrientes ofertados e consumidos foi estatisticamente significante (p < 0,05) para fibra, vitamina A, vitamina C, cálcio, ferro e zinco.

Abstract Analyzing quantitative and qualitative aspects of school meals represents the initial stage to ensure that the National School Food Program (PNAE) is an effective space for the promotion of healthy eating habits and establishing individual rights. The objective of this study was to evaluate the nutritional adequacy of meals served and consumed, as well as quantifying food waste in Child Daycare Centers in Maceió, in the state of Alagoas. All meals served and consumed by 359 children (aged 17 to 63 months) were analyzed by the direct weighing method for three non-consecutive days in all institutions. Food waste was determined by the leftover factor and the nutritional value of meals served and consumed was compared to the PNAE reference values regarding energy, carbohydrates, protein, lipids, vitamins A and C, iron, calcium, zinc, magnesium and fiber. Of the 85 meals/preparations featured on the menu, 58 (68%) revealed a high leftover percentage; in excess of 10%. The meals served and consumed met approximately 50% of the recommended energy and macronutrient values. The difference between the averages of the nutrients offered and consumed was statistically significant (p < 0.05) for fiber, vitamin A, vitamin C, calcium, iron and zinc.

Risk Management Study for Preventing Population Decline in the Low Fertility Age

PURPOSE: The purpose of this study is to identify variation in pregnancy wastage prevalence by type and age among married women aged 15~44 in Korea. METHODS: The study data is based on 3% patient sample data extracted from the Health Insurance Review & Assessment Service in 2011 and 2014. For analysis, ANOVA and t-tests were performed using the SAS program. All data was weighted. RESULT: The number of women experiencing pregnancy wastage in Korea was approximately 110,000 and 114,000 in 2011 and 2014 respectively, figures 20% higher than the equivalent numbers of births in both cases. Of wastage types, spontaneous abortion was shown to have the highest prevalence, while the 30 to 34 years category represented the highest prevalence among age groups. Test outcomes regarding age difference demonstrated that, in 2011, the average maternal age in the “other abortion” type was older than that for spontaneous abortion. Age was shown to have a significant effect on surgery status; surgery experience was associated positively with maternal age. CONCLUSION: In this study, we defined terms for pregnancy wastages, derived the diseases codes related to pregnancy wastages, and ascertained the status of pregnancy wastage among women in Korea. Consequently, we suggest that the problem of pregnancy wastage in Korea should be recognized not only as a personal, but also a community, social, and national issue.

Harvesting the uncollected fruits of other people's intellectual labour / Beneficiarse de los frutos inutilizados del trabajo intelectual ajeno / Colhendo os frutos não coletados do trabalho intelectual de outras pessoas

Abstract: Intellectual property regimes necessarily create artificial scarcity leading to wastage, both by blocking follow-up research and impeding access to those who are not able to pay the full retail price. After revising the traditional arguments to hinder access to people's intellectual labour, we examine why we should be more open to allow free-riding of inventive efforts, especially in cases where innovators have not secured the widest access to the fruits of their research. We do so by questioning the voluntariness involved in the consumption of objects of innovation, restating the positive social externalities that arise when wider access to the fruits of innovation is facilitated, and examining the eventual harms innovators face.

Resumen: Los regímenes de propiedad intelectual crean necesariamente una escasez artificial que conduce al despilfarro, tanto mediante el bloqueo de investigación derivada y al prohibir el acceso a aquellos que no son capaces de pagar el precio total de venta. Después de analizar los argumentos tradicionales para limitar el acceso al trabajo intelectual ajeno, examinaremos por qué debemos ser más abiertos en permitir el uso gratuito de los esfuerzos inventivos ajenos, especialmente en los casos en que los innovadores no han ofrecido el más amplio acceso a los frutos de sus investigaciones. Para este propósito cuestionaremos la voluntariedad involucrada en el consumo de los objetos de la innovación, mencionaremos las externalidades sociales positivas que surgen cuando se facilita un mayor acceso a los frutos de la innovación, y haremos un examen del tipo de daños que los innovadores eventualmente enfrentan.

Resumo: Os regimes de propriedade intelectual criam, necessariamente, escassez artificial, levando ao desperdício, tanto por meio do bloqueio de pesquisa de acompanhamento quanto pelo impedimento dreo acesso àqueles que não são capazes de pagar o preço comercial total. Após rever os argumentos tradicionais para dificultar o acesso ao trabalho intelectual, nós examinamos porque nós devemos ser mais abertos e permitir o parasitismo dos esforços inovadores, especialmente em casos no qual os inovadores não têm assegurado o acesso mais amplo aos frutos de sua pesquisa. Nós o fazemos por questionar a voluntariedade envolvida no consumo de objetos de inovação, reafirmando as externalidades sociais positivas que surgem quando o acesso mais amplo dos resultados da inovação é facilitado, e examinar a eventuais prejuízos que os inovadores possam enfrentar.

Green synthesis of silver nanoparticles using aqueous extract of saffron (Crocus sativus L.) wastages and its antibacterial activity against six bacteria

Objective To synthesis silver nanoparticles (AgNPs) by using extract of saffron (Crocus sativus L.) wastages and to test their antibacterial activity against six bacteria. Methods In this paper, the synthesis of AgNPs using aqueous extract of saffron wastage as a green method without any chemical stabilizer and reducer is demonstrated. The synthesized AgNPs were determined by UV–vis spectrum, high resolution transmission electron microscopy, X-ray diffraction, and Fourier transmission infrared spectroscopy analysis. Results UV–vis spectrum showed a peak at 450 nm due to excitation of surface plasmon vibrations. Fourier transmission infrared spectroscopy showed that nanoparticles were capped with plant secondary metabolites. X-ray diffraction analysis also demonstrated that the size range of the synthesized nanoparticles was 12–20 nm. Transmission electron microscope image illustrated AgNPs with spherical shape and an average size of 15 nm. The result of antibacterial activities showed that the biosynthesized AgNPs had an inhibiting activity against Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumonia, Shigella flexneri and Bacillus subtilis. Conclusions The biosynthesized AgNPs showed significant antibacterial effect against Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumonia, Shigella flexneri and Bacillus subtilis, so, it can be used in biomedical applications.

Lessons learnt from a measles outbreak in Madang Province, Papua New Guinea, June 2014 – March 2015

Objective: This study examined measles vaccine wastage during an outbreak response in Madang Province of Papua New Guinea from June 2014 to March 2015. Methods: Vaccine wastage was defined as the number of doses received by a health centre minus the total number of doses administered during and returned following the outbreak vaccination campaign. Vaccine data were collected from the Provincial Health Information Office, the Provincial Vaccine Store register and clinic and health centre immunization registers for calculating the vaccine wastage. Interviews were conducted with all 48 health centres involved in the outbreak response using a structured questionnaire to explore the reasons for vaccine wastage. Results: Of the 154 110 doses issued by Madang Province during the outbreak, a total of 85 236 (55%) doses were wasted. The wastage varied by district from 31% to 90%. The total cost of the vaccine wastage was estimated to be 589 810 Kina (US$ 196 604). None of the health centres maintained vaccine stock registers. Most health centres indicated multiple failures in cold chain logistics. Almost 40% of health centres reported incorrectly diluting vaccines. The same percentage of health centres reported using incorrect injection techniques. Discussion: Regular audits of cold chain logistics, staff training and improved processes for recording vaccine administration and wastage will decrease vaccine wastage during vaccine-preventable disease outbreaks and also benefit routine immunization activities.

Emotions toward water consumption: Conservation and wastage / Emociones hacia el consumo de agua: desperdicio y sostenibilidad

Water is a key element for the human survival but unsustainable patterns of water consumption are still evident. Many factors influence water conservation but the existing literature investigating psychological determinants of water conservation have so far focused on cognitive or motivational factors. However, there is growing evidence for the important role of emotions as predictors of environmental engagement in general and water conservation in particular. The present article contributes to this recognition of the role of emotions by reporting two studies on the development and validation of a measure to access negative emotions regarding water wastage, the Rating Scale of Emotions towards Water Wastage (RSEWW). Results confirmed that this 12-item scale form a unidimensional measure that reliably predict participants' behavioral intention to participate in activities for the water conservation. Theoretical and practical implications from the findings are discussed in relation to the extant literature.

El agua es un elemento clave para la supervivencia humana, pero los patrones no sostenibles de consumo de agua siguen siendo evidentes. Muchos factores influyen en la conservación del agua, pero la literatura existente que investiga los determinantes psicológicos de la conservación del agua, hasta el momento, se han centrado en los factores cognitivos o motivacionales. Sin embargo, existe una creciente evidencia de la importancia del papel de las emociones como predictores de la participación en la conservación del medio ambiente en general y del agua en particular. El presente articulo contribuye a este reconocimiento del papel de las emociones en la exposición de 2 estudios sobre el desarrollo y validación de una medida para acceder a las emociones negativas con respecto a desperdicio de agua, la Escala de Evaluación de las Emociones hacia el Desperdicio de Agua (Rating Scale of Emotions towards Water Wastage [RSEWW]). Los resultados confirmaron que esta escala de 12 items forma una medida unidimensional que prevé de manera fiable la intención de conducta de los participantes para intervenir en las actividades para la conservación de agua. Implicaciones teóricas y prácticas de los hallazgos se discuten en relación con la literatura existente.

Geração de resíduos sólidos em um restaurante de um Hotel da Serra Gaúcha, Rio Grande do Sul, Brasil / Solid waste generation in a hotel restaurant in Serra Gaúcha, Rio Grande do Sul, Brasil

RESUMOEstudos sobre a geração de resíduos sólidos e desperdício de alimentos em restaurantes são importantes e necessários para a gestão gastronômica e definição de planos de gerenciamento de resíduos sólidos. Essa pesquisa avaliou o balanço mássico de um restaurante de um hotel na Região Turística Uva e Vinho no Rio Grande do Sul. Foram coletados dados durante períodos de alta e baixa temporada, caracterizados pela ocorrência ou não de eventos na região (nove semanas intercaladas). Todos os alimentos crus e processados (utilizados no preparo das refeições e oferecidos aos hóspedes) e os resíduos gerados foram quantificados. Constatou-se que o desperdício de alimentos ocorre, em geral, devido à oferta ser maior do que o consumo. Conclui-se sobre a importância do desenvolvimento de estudos direcionados à geração e descarte de resíduos sólidos em restaurantes no sentido de otimizar os procedimentos no planejamento gastronômico, reduzir o desperdício de alimentos e adotar técnicas de reaproveitamento e de tratamento desses resíduos.

ABSTRACTStudies on the generation of solid waste and food waste in restaurants are important and necessary for the culinary management and the definition of plans for solid waste management. This research evaluated the mass balance of a hotel restaurant in the touristic region Uva e Vinho in Rio Grande do Sul Data were collected during periods of high and low season, characterized by the occurrence of events in the region (nine weeks interspersed). All raw and processed food (used in the preparation of meals and offered to guests) and waste generated were quantified. It was found that the food waste generally occurs because the supply is larger than the consumption. We conclude on the importance of the development of studies directed to the generation and disposal of solid waste in restaurants in order to optimize the procedures in the gastronomic planning, reduce food waste and adopt techniques of reuse and treatment of this residues.

Evaluation of ‘Wastage Rate’ of Blood and Components – An Important Quality Indicator in Blood Banks.

Aims: To evaluate the wastage rate of blood and components in a newly established blood bank of a teaching hospital in West Bengal. Study Design: Retrospective study. Place and Duration of Study: Department of Transfusion Medicine, IQ City Medical College and Narayana Multispeciality Hospital, Durgapur between April 2014 and October 2014. Methodology: The study recorded the discarding of whole blood and component units due to various reasons viz. over-collection and under-collection of blood from donors; RBC contamination of plasma and platelets; blood bag leakages; presence of hemolysis, clots, lipemic appearance, greenish and yellowish (icterus) discoloration; expiry date and seroreactivity for infectious diseases. The wastage rate was calculated thereafter using appropriate formula. Results: Out of total 1241 blood bags which were collected from donors during the study period, 1176 units were separated into components and rest 65 units were kept as whole blood units. Total 93 (7.49%) blood bags were discarded, of which 27 (2.18%) were whole blood bags and 66 were components. The total number of whole blood units issued during this period was 38 and components issued during this period were 693. Therefore, the wastage rate of whole blood units and components can be calculated as: Wastage rate of whole blood = 27/38 x100 = 71% Wastage rate of components = 66/693 x100 = 9.52% Conclusion: The rate of discarded blood components or “wastage rate” is one of those indicators and has been listed third among the ten quality indicators recommended by National Accreditation Board for Hospitals and Health Care providers. It is important to monitor this parameter for judicious management of blood bank inventory.

Medicines Wastage at a Tertiary Hospital in Dar Es Salaam Tanzania.

Medicines wastage is a problem in health care delivery systems, however the extent of this wastage and associated factors in many health care settings is less known. The objective of this study was to assess medicines wastage and its associated factors in a hospital setting in Dar es Salaam city Tanzania. Specifically to determine major types of medicines wasted and to identify factors contributing towards the wastage. A cross sectional study was carried out at a tertiary hospital, where patient files were analyzed for last admission treatment information for the year 2012. Results show that about 56.3% of medicines prescribed were dispensed to patients. Out of the dispensed medicines, 730 medicines dosages were wasted. Anti-infective medicines wastage was 18.9%, cardiovascular medicines (8.9%) and the other categories was 23.7% of the total medicines dispensed. The factors contributing to medicines wastage were excess (44%), pilferage (26.5%), patient death and change/stop of medicines. Excess supply and pilferage were the major contributing factors. Measures should therefore be taken to mitigate the sources of wastage identified by this study so as to ensure availability of medicines and their rational use in hospital settings.

Maternal Risk Factors & Pregnancy Wastage in a Rural Population of Jammu District.

To study the association of maternal risk factors with pregnancy wastage, a prospective study was conducted for a period of one year among 305 pregnant rural women registered with fifty Anganwadi centres in field practice area of Department of Community Medicine, GMC Jammu. All the potential participants were interviewed in person using semi-structured, pre-tested proformae and evaluated clinically. All pregnant women were then followed to study the outcome in terms of abortion, live birth or still birth. Various maternal risk factors like anaemia, Hypertension, Ante partum Haemorrhage, Albuminuria, Glucosuria were studied and their association with pregnancy wastage was analysed using chi-square test. Out of 305 pregnancies followed, 43(14.1%) ended in pregnancy loss i.e. 34 abortions and 9 still births. Pregnancy wastage was statistically significantly associated with anaemia, H.T., APH and Glucosuria. Anaemia was found to independently affect adverse pregnancy outcome on multivariate analysis. Pregnancy wastage in our set up is mainly due to preventable and treatable risk factors which should be taken care of to prevent the wastage.
