 Due to blood supply problems, the cost of blood processing, and the complications of blood transfusion, it is very important to observe the indications for blood transfusion. In addition, necessary precautions should be taken for blood transfusion. Therefore, this study was performed to evaluate the criteria for receiving blood products as well as transfusion complications in patients referring to the emergency department. 

 This study was a descriptive-analytical and cross-sectional study. All patients who referred to Imam Hossein and Shohadaye Tajrish Hospitals and needed to receive blood products during 36 months from April 2016 to March 2018 were evaluated. The data collection tool was a researcher-made checklist that included demographic characteristics, injection indication, and transfusion complications. After collection, the data were entered into SPSS statistical software version 18 and analyzed using Chi-square and Fisher's exact tests. 

 The mean age of patients was 43.51 ± 20.05 years. Sex distribution showed that 61.5% were male. The results showed that the amount of blood products consumed was 2041.28±161.309 units for all patients and 410.89±52.056 units in the emergency department. O and AB blood groups had the highest and lowest frequencies, respectively. In terms of injection indication, trauma was the most common. A difference was observed between the amounts of reserved and consumed products in the emergency department: 357.25±62.105 units for packed cells, 123.33±28.238 units for fresh frozen plasma, 71.533±21.313 units for blood platelets, and 53.78±12.069 units for cryoprecipitate. In terms of complications, shivering (22 cases) was the most common. The results showed that the difference between the mean reserve of compressed blood cells in 2016 and 2017 was significant (P = 0.029). There was also a significant difference between reserved platelete units in 2016 and 2018 (P=0.031). 

 Blood reservation should be done according to specific instructions, and quantitative and qualitative control in the field of blood reservation and consumption in medical centers is necessary. Also, reducing the number of unnecessary injections of blood product units to patients can be one of the effective factors in reducing the complications of blood transfusion.

Since the blood product should be in certain conditions from the time of blood donation to injection to the patient, the necessary care should be taken and certain monitoring of blood should be made. Therefore, medical personnel should be expert in blood transfusion science, which has many importance in Iranian law and Imamie jurisprudence.

The present research methodology is descriptive-analytical and based on the library analysis of legal regulations and jurisprudence.

In Imamie jurisprudence, there should be three rules that include: Indulgence (presentation of necessary warnings to medical staff and transfer of education to blood-borne patients), the need for the elimination of probable losses (the need to provide training to reduce the probable potential losses due to the ignorance of the medical staff of the transfer of blood), as well as the requirement to warn al-Jahal (medical staff) that should be trained in curative care about the blood that is in their care.

The basis of consumer include: the need to attract trained people in the blood center, the need to use the trained personnel in the quality assurance section, to establish a general educational program for the whole blood transfusion department, the need for training the Central Transfusion Committee (CTC), the Senior Medical Assistance Commitment to Provide Training, which can be considered as the most basic legal basis for the expertise of medical personnel for transfusion medicine.

Excessive blood request is a common problem in hospitals. For this purpose, there are some programs called the Maximum Surgical Blood Ordering Schedule (MSBOS) for proper management of blood demand. The aim of this study was to evaluate the demand for blood and blood consumption in different parts of the Children's Medical Center, Tehran.

In the retrospective study, from 2006 to 2016, 17,696 blood transfusions from all 19 parts of the hospital were reviewed. The ratio of blood consumption to the antibody screening test was studied. The second study was conducted on cross-match to transfusion (C/T) Ratio on 15,310 cross-matched blood requests that were measured in the hospital in 2017.

The results of the first study showed of 176696 blood transfusion requests, 77% were consumed. The first study showed that the highest demand was for the surgical department and the lowest request was for the NICU department. C/T Ratio was 1.3 in the second study.
 

The first study showed that 23% of the donated blood was unused. This proves that performance of antibody screening test would bring about economic savings and time reduction in blood preparation especially in emergency situations. The results of the second study (C/T ratio mean = 1.3) indicated the correct blood ordering procedures performed by the hospital have led to blood saving.

One of the most fundamental rights of consumers of blood products should be the right to health, according to which the right should be recognized by the Blood Transfusion Organization and all necessary measures to collect healthy and safe blood to the consumer. The main purpose is to establish relationships between consumers of blood products and explain the various aspects of their right to health as their most fundamental right.
 

This descriptive-analytical study is based on library analysis of legal regulations and jurisprudence. Therefore, the present study did not have a definite sampling because of its qualitative nature.
 

This right is supported by jurisprudential rules such as the rule of no-harm, casuality and loss, and there are precise enforcement guarantees in jurisprudence that can serve as a general basis for blood transfusion and blood products, and in Iranian law as well. The right basis is found, and this right is specifically mentioned in the Statute of the Organization and in the Executive By-Law of the Activities of Blood Banks and Blood Consumer Centers.
 

 

Ultimately, about the consumer of blood products, the right to health has been acknowledged as the institution of blood monitoring and care. According to the Hemovigilance Division, the Blood Quality Assurance Division fulfills this obligation as well as the legislator responsible for blood bank. There have also been commitments to the need for healthy blood, which affirm the respect for the right of consumer of blood products to the right to health.

The improvement of the quality of health care services, the enhancement of the safety in services, the establishment of patient satisfaction, and hemovigilance are some of the main factors which illustrate the necessity of using new technologies in health care services. RFID is a type of wireless technology which can help to increase the quality of services provided in hospitals. The purpose of this study is to identify waste in the blood use in hospitals, apply tracking tools to improve the use of blood products, and reduce the loss of blood.
The research is based on the real and tangible need in the hospital environments and it is an applicable research. To find the impact of RFID system on the improvement of service quality and the reduction of the blood wastage, it was put to a simulation test that was favored over the real test for the reasons of cost effectiveness. In this study, after reviewing the current situation and identifying the causes of blood wastage, “Discrete Event” simulation and Enterprise Dynamic (ED) software were used to simulate the proposed model and improvement scenario (using RFID).
Simulation results show that the average total loss of blood products, after implementation of RFID (over six months), has experienced a decrease rate of about 75%.
RFID system can affect the inventory management, and make real-time tracking and recording of information possible thereby ensuring more accuracy in blood transfusion attempts.

Every single donated blood unit is a valuable capital. The aim of this study is to evaluate the rate of blood consumption in Kerman hospitals and suggest solutions to reduce the blood wastage. This 4-year study evaluates the blood usage and wastage in three selected Kerman hospitals one affiliated to a university hospital، the other to the Social Security Organization، and the last to the private sector. The average usage of pack RBCs is higher than other products in the three hospitals: the university hospital 4190. 25 ± 765. 66 units per year، the Social Security Organization affiliated hospital 1660. 75 ± 162. 31 units per year، and the private hospital 231. 8 ± 62. 9 units per year. Annually، in the university hospital the average request of blood per active bed is 15. 09 units/bed and the average usage is 14. 8 units/bed; cross matched to transfused blood (C/T) rate is not detectable due to inappropriate cross match registry in the university hospital. In the Social Security Organization affiliated hospital، the average blood request is 6. 1 units/bed and the average blood usage is 4. 9 units/bed; the C/T ratio is 1. 6. In the private hospital، the average blood request is 5. 2 units/bed and the average blood usage is 4. 4 units/bed; the C/T ratio is 2. 9. The evidence shows that the blood usage in Kerman hospitals is approximately similar to the global standards. Since the preparation of a blood unit costs a lot of financial and intellectual charges، improving blood usage based on international standards is necessary.

Wrong blood transfusion brings about adverse complications. Case: we present a 62 year old male with history of chemotherapy for his leukemia. 400mL of blood had been administered before we became aware that it was mismatched. Transfusion was immediately terminated and the supportive therapy began. He was transferred to the intensive care unit. After three days when the liver enzymes were normal, he was discharged.

In this patient, despite mismatched blood transfusion, surprisingly no adverse events happened; the probable explanation is that immunosuppresion due to chemotherapy helped prevent serious complications. However, measures should be taken in the first place to prevent blood transfusion errors and to this end multiple preadministration checking is strongly advised.

Blood bank refrigerators play the main role in blood safety and appropriate blood production. Confirmation of their functions to maintain temperature stability with a PM program is compulsory. The main objective of this study is to identify the level of maintenance and regional climate effects on blood bank refrigerators in different blood centers. In order to study the level of maintenance and possible regional climate effects on each blood bank refrigerator، a survey on 85 local refrigerators in seven regional blood centers was carried out. In this survey، along with the amount of temperature leakage from the body and glass insulators، the quality of ribbons used was also evaluated. The results obtained from this study showed the degree of temperature leakage on bodies of the fridges، metal doors، and glasses to be varied due to different factors like room humidity and temperature changes، air flow around refrigerators، and spaces between refrigerators and other appliances or wall. This study contributes to a higher knowledge level of local manufacturers on how better to produce blood bank refrigerators to be compatible with different climate conditions of Iran.

Blood transfusion committees supervise the blood quality, preparation process of blood transfusion, blood transfusion indications, appropriate use of blood products, and report on blood transfusion complications. The aim of the present study was to evaluate hospital blood transfusion committees in Tehran (2008-2009). In this retrospective study, 143 hospital blood transfusion committees were reviewed. Received reports from hospital committees were the basic data for evaluation. According to the hospital blood bank regulations, appropriate data were extracted from their reports. Statistical analysis was performed by SPSS 19 software. Out of 143 hospitals, 38(27%) submitted their performance reports of the blood transfusion committees to the Tehran Blood Transfusion Center. Committees’ reports were studied based on six performance indicators. The most frequent reported indicator was about reports of the number of committees formed (76%) and the least frequent reported indicator was about transfusion complications (4%). Other reported indicators in descending order included preparation process of blood transfusion (66%), report statistics for the number of blood transfusions (42%), reports about blood transfusion indications (34%) and reports about training programs (28%). Mean scores of monthly transfusions in public and private hospitals were 5.7(2.5-9) and 7.1(4.3-10), respectively with significant differences (p<0.01). None of military hospitals had submitted their reports of monthly transfusion when we were conducting the present study. Findings show an increase in activities of Tehran hospital blood transfusion committees by 20% compare d with the last study in 2005-2006, but more training programs should run to improve the performance quality of the committees.
