For example, when writing a procedural document for the first time – the initial draft will be version 0. It has been developed to comply with national requirements relating to the care and maintenance of endoscopes. The Health and Social Care Act 2008 Code of Practice on Infection Prevention and Control requires healthcare providers to ensure decontamination of reusable medical devices takes place in compliant facilities that are designed for the process of decontaminating medical devices through validated processing systems and controlled environmental conditions to ensure all potential environmental, cross-infection, handling and medical device usage risks are minimised. The policy provides detail on; Responsibilities of the endoscope user and managers of Endoscopy units Specific guidance for different endoscopes including rigid and flexible types. The highest standards of cleaning and decontamination must be achieved in order to prevent cross-infection. These national recommendations contain Essential Quality Requirements, which all organisations are expected to comply with, as well as Best Practice guidance, to which organisations are expected to work towards, encompassing non-mandatory policies and procedures that aim to further minimise risks to patients, deliver better patient outcomes and achieve cost efficiencies. Standard infection control precautions also apply to use, care, decontamination and maintenance of endoscopes; these must be applied rigorously during all procedures involving potentially contaminated endoscopes. It applies to all types of endoscope used throughout the Trust and to all staff involved in the use, care, decontamination and maintenance of endoscopes. Ensuring that if used in departments without direct access to the decontamination unit, endoscopes are kept moist and are transported to the decontamination unit immediately after use in an appropriate container, in line with the guidance in this policy. Ensuring that flexible, heat labile endoscopes are appropriately stored in a designated climate controlled drying cabinet or other approved storage area and are reprocessed before use in accordance with guidance in this policy Ensuring that rigid and heat stable endoscopes are stored in clean, dry conditions when not in use. Standard precautions including handwashing, gloving and the use of barrier precautions such as aprons (where appropriate) must be used and high standards of personal hygiene are required from staff. Endoscopes should be transferred from the point of use to the decontamination area as soon as possible, following the procedures in 7. Future purchasing and service developments must recognise the recommendations for best practice for automated centralised decontamination of such devices. Scopes must be able to tolerate approved decontamination methods and comply with this policy. The Department purchasing the accessory is responsible for carrying out risk assessment prior to purchase to ensure single use only. This is in addition to the requirement to document the endoscope number in the patient’s records. These must include: An environment that allows flows of work to pass from “dirty” to “clean” without crossover or potential for cross-contamination. Thorough cleaning of all lumens must be achieved prior to automatic processing with a chemical disinfectant / sterilant. After use: Care, Decontamination & Maintenance of Endoscopes & Similar Devices Policy Version No 6. If endoscopes are allowed to dry during this period, soil will be difficult to remove. Therefore endoscopes should be transferred from the point of use to the decontamination area as soon as possible and an appropriate dedicated container must be used. Manual cleaning: Follow local protocols which should be based on instructions provided by the endoscope manufacturer, as endoscopes vary in construction and therefore the method of cleaning required.
Cerebral aneurysms are abnormalities of the arteries gastritis diet plan uk purchase sevelamer 800mg on-line, often found at the base of the brain diet while having gastritis proven sevelamer 400mg. Eighty to gastritis symptoms home remedies purchase sevelamer 800 mg online eight five percent of these lesions are in the anterior cerebral circulation (internal carotid artery and its branches) gastritis diet mayo order sevelamer 800 mg on line, with the remainder located in the posterior circulation (vertebral arteries and its branches). Multiple cerebral aneurysms are found in approximately twenty five percent of cases. Small areas of rounded or irregular swellings in the arteries can cause the vessel walls to become weak and prone to rupture, leading to a hemorrhagic stroke. Ruptured intracranial aneurysms account for approximately eighty percent of non-trauma subarachnoid hemorrhages. Death can occur if the intracranial pressure is high enough to cause irreversible structural damage or halt cerebral perfusion. The prevalence of aneurysms is two hundred times higher than the annual incidence of subarachnoid hemorrhage, leading to the conclusion that most aneurysms do not rupture. Treatment of the ruptured aneurysm is recommended as soon as tolerable by the patient, with the goal of obliterating the aneurysm within one to three days after the hemorrhage. Microsurgical aneurysm clipping and endovascular coil embolization are two very popular treatments. In microsurgical clipping, the neurosurgeon opens the dura, identifies the parent vessel and the ruptured aneurysm, and clips the aneurysm to exclude it from circulation. Endovascular coiling uses a micro-catheter threaded through a guide catheter to the origin of the ruptured aneurysm. Once inside the aneurysm, platinum coils are inserted into the sac until the aneurysm is densely packed. Coil therapy requires serial monitoring of patients and follow-up cerebrovascular imaging to detect the occasional risk of coil compaction or aneurysm recanalization. Initial treatment yields approximately seventy percent of patients experiencing ninety five to one hundred percent occlusion of the aneurysm. However, twenty five to thirty percent of patients do not have complete obliteration of their aneurysms, and recanalization can occur. The decision to proceed with open surgical clipping or endovascular treatment of an intracranial aneurysm after subarachnoid hemorrhage depends on both aneurysm-specific factors (location, size, morphology, and presence of thrombus), and patient-specific factors (age, density of the subarachnoid hemorrhage, patient preference, and other medical comorbidities). Concussions occur when the head or body is hit hard, or violently jarred or shaken. This causes the brain to crash into the skull, resulting in a disturbance of brain function. Problems can persist for months or even years in as many as thirty percent of patients. More than ten years ago, a federal study labeled concussions as “a serious public health problem”, costing the United States an estimated eighty billion dollars per year. Regardless of how a concussion occurs whether it is due to an accident, athletic event, or combat it can lead to permanent loss of higher level mental processes. As the media continues to keep the issue of concussions in the forefront of the news, researchers are working with imaging modalities to better detect the subtle brain damage that concussions can cause. By preventing and repairing the damage that accompanies mild traumatic brain injuries, we may be able to limit their long-term effects. Concussion researchers are finding that symptom resolution is not necessarily injury resolution. A concussion is not a single pathology, but many different injuries with different symptoms. Patients with more severe symptoms, such as persistent headaches and difficulty concentrating or remembering things, showed the most substantial differences in their images. A concussion can place stresses and strains on the fiber tracts between the two halves of the brain that make up the corpus callosum, disrupting both the physical and functional connections between the two halves. Imaging data was reviewed for patients suffering with the concussion effects of vestibulopathy, which includes dizziness, imbalance, and visual problems, as well as those with ocular convergence insufficiency, a condition in which the eyes do not turn inward properly when focusing on a nearby object. Previous thought held that vestibulopathy was related to the inner ear, rather than to a brain injury. The microbleeds were distributed throughout the brain, whereas the linear lesions were found mainly in one area, and were more likely to be associated with injury to adjacent brain tissue. It was hypothesized that the linear lesions may represent a type of vascular injury seen in the brain tissue studies of people with more severe traumatic brain injury. Researchers hypothesized that the increased levels of carbon dioxide would most closely simulate the physiologic challenge that occurs when physical activity is resumed. The widening of blood vessels as a result of the increased carbon dioxide may be an indicator of acute injury and contribute to recurrent headache symptoms. The test is performed at rest, where it can measure the brain’s overall level of activity. Athletes who had experienced concussions without residual symptoms performed as well as control athletes on neuropsychological and mild exercise tests that are commonly used to determine if an athlete has recovered from a concussion. Activity representing the strength of connections between the left and right halves of the brain was lower, or weaker, suggesting that the injured athletes had not fully healed ten days after their concussions symptom resolutions were not necessarily injury resolutions. Both sets of athletes were scanned again after mild exercise tests, which revealed similar brain activity in both groups. These results suggest that treating concussed athletes with certain mild exercises may warrant further study. These patients showed increased frontal connectivity around the medial prefrontal cortex, which is thought to represent brain neuroplasticity operating in recovery and neural repair after injury. Researchers also found reduced connectivity in the posterior cingulate cortex and parietal regions of the brain, which correlates clinically with neurocognitive dysfunction. This is a degenerative condition caused by a buildup of tau protein that has been associated with memory loss, confusion, progressive dementia, depression, suicidal behavior, personality changes, abnormal gait and tremors. The athletes also displayed more depressive symptoms, and scored lower on clinical assessment tests, demonstrating evidence of cognitive loss. Bacteria and viruses are the most common infections, but parasites, fungi, and other microorganisms can also invade the brain. An infectious agent can cause inflammation of the area that it invades; the area then lends its name to the infectious disease. Meningitis is the inflammation of the meninges, which are the three layers of membranes that surround the brain and spinal cord, including the cerebrospinal fluid. Meningitis is typically either viral or bacterial, with viral infections being two to three times more common. Viral meningitis causes milder symptoms, requires no specific treatment, and typically goes away without complications. Bacterial meningitis is much more serious, and can result in a learning disability, speech defects, hearing loss, seizures, loss of extremity function or amputation, permanent brain damage, and even death. Up to fifteen percent of the survivors of bacterial meningitis are left with permanent complications and health issues. The overall incidence of bacterial meningitis in the United States has decreased significantly since 1998, as a result of widespread vaccination. It usually occurs in isolated cases, as opposed to epidemics, and approximately two-thirds of all cases are in children. Bacterial meningitis is more common in males, and occurs more often in late winter and early spring. From a worldwide perspective, bacterial meningitis is still common, and is a serious threat to global health. It particularly affects the African continent, with regular epidemics in sub-Saharan and West Africa, areas also known as “the meningitis belt. A vaccine against pneumococcal meningitis can also prevent other forms of infection. It is not effective in children under the age of two years, but it is recommended for all those over the age of sixty five, and for younger people with certain chronic medical conditions. The meningococcal vaccine is used to control outbreaks in certain regions of the country, in overcrowded environments (such as college dormitories), and as a preventive measure for travelers outside the U. Hib vaccines are now part of routine pediatric immunizations, and have significantly reduced the occurrence of serious Hib disease. Most of the bacterias that cause meningitis are not very contagious, requiring the exchange of respiratory and throat secretions through coughing, sneezing, or kissing, to spread the bacteria. The exception is meningococcal meningitis, which has an increased risk of spreading to those in the same household, those with prolonged contact, or those in direct contact with a patient’s oral secretions.
These indicators detect enzymes of Geobacillus stearothermophilus (the test organism for steam sterilizers) by reading a fluorescent product produced by the enzymatic breakdown of a nonfluorescent 29 substrate gastritis symptoms in cats buy generic sevelamer 800 mg line. There are six classes of chemical indicators (see Table 2 gastritis diet therapy 400 mg sevelamer amex, ‘International Classes of Steam Chemical Indicators’) gastritis symptoms livestrong discount sevelamer 800 mg line. Routine monitoring of sterilizers involves the assessment of physical parameters of the sterilizer cycle gastritis diet ùåíÿ÷èé proven sevelamer 400mg, chemical indicators and biological indicators. Facilities that use ethylene oxide for sterilization must comply with the requirements of the designated substance regulation – 38 ethylene oxide (O. Best Practices for Cleaning, Disinfection and Sterilization in All Health Care Settings | May 2013 41 Recommendations 51. A biological indicator shall be used to test the sterilizer each day and for each type of cycle that it is used; in every load subjected to ethylene oxide sterilization; and in every load containing implantable devices. Sterilizers shall be subjected to rigorous testing and monitoring on installation and following disruptions to their normal activity. Effective sterilization is impaired if all the necessary parameters of the process are not met. These include, but are not limited to, the following: Decontamination and sterilization areas must meet the requirements for processing space as noted in Appendix C, ‘Recommendations for Physical Space for Reprocessing’, and shall not be located in the operative procedure room or near any potential source of contamination, such as sinks, hoppers, linen or 1 trash disposal areas. Best Practices for Cleaning, Disinfection and Sterilization in All Health Care Settings | May 2013 42 Recommendation 58. Reprocessing Endoscopy Equipment/Devices For the purposes of this document, endoscopes will be considered to be of two types: Critical Endoscope: Endoscopes used in the examination of critical spaces, such as joints and sterile cavities. Semicritical Endoscope: Fibreoptic or video endoscopes used in the examination of the hollow viscera. These endoscopes generally invade only semicritical spaces, although some of their components might enter tissues or other critical spaces. Semicritical endoscopes require a minimum of high-level disinfection prior to use. Opinions differ regarding the reprocessing requirements for flexible bronchoscopes and cystoscopes. Since they are entering a sterile cavity, it is preferred that bronchoscopes and cystoscopes be sterilized; however, if the cystoscope or bronchoscope is not compatible with sterilization, high-level disinfection is the minimum requirement. Due to the complexity of their design, flexible fibreoptic and video endoscopes (‘semicritical endoscopes’) 14,40 require special cleaning and handling. Endoscopic cleaning shall take place immediately following 14 completion of the clinical procedure, as soil residue in endoscope lumens dries rapidly, becoming very difficult to remove. Best Practices for Cleaning, Disinfection and Sterilization in All Health Care Settings | May 2013 44 Soak and manually clean all immersible endoscope components with water and a recommended cleaning agent prior to automated or further manual disinfection or sterilization. The following steps must be included in the disinfection/sterilization procedure: Choose a disinfectant that is compatible with the endoscope. Depending on the intended use of the device, tap water followed by a 70-90% alcohol 41 rinse may be acceptable. High-level disinfection of cystoscopes should be followed by a sterile water 29 43 rinse. A disposable sheath/condom placed over the endoscope during use reduces the numbers of microorganisms 44 on the scope but does not eliminate the need for cleaning/disinfection/sterilization between uses. If reusable biopsy forceps/brushes are used, they must be meticulously cleaned prior to sterilization using ultrasonic cleaning. Best Practices for Cleaning, Disinfection and Sterilization in All Health Care Settings | May 2013 46 14, 40 Record the endoscope number in the client/patient/resident record. Individuals responsible for reprocessing endoscopes shall be specially trained and shall meet the facility’s written endoscope processing competency requirements, including ongoing education and training and annual competency testing. Endoscope cleaning shall commence immediately following completion of the clinical procedure. Patency and integrity of the endoscope sheath shall be verified through leak testing, performed after each use. Final drying of semicritical endoscopes shall be facilitated by flushing all channels with filtered air, followed by 70% isopropyl alcohol, followed by forced air purging of the channels. Semicritical endoscopes shall be stored hanging vertically in a dedicated, closed, ventilated cabinet outside of the decontamination area and procedure room. Healthcare settings shall have policies in place providing a permanent record of endoscope use and reprocessing, as well as a system to track endoscopes and clients/patients/residents that includes recording the endoscope number in the client/patient/resident record. Unacceptable Methods of Disinfection/Sterilization the following methods of disinfection/sterilization are not recommended. Boiling water is inadequate for the destruction of bacterial spores and some viruses. It is not 23 an acceptable method of disinfection/sterilization for medical equipment/devices. Glass bead sterilizers are difficult to monitor for effectiveness, have inconsistent heating resulting in cold spots, and often have trapped air which affects the sterilization process. Glass bead sterilization is not an acceptable method of 23, 47 sterilization for medical equipment/devices. Chemiclaves are occasionally used in 48 dentistry, although steam sterilization is preferred due to the lack of penetration achieved in a chemiclave and 49 an overall failure rate of almost 5%. If used, a chemiclave must be monitored with mechanical, chemical and biological monitors as is any other sterilizer. Because of the environmental risks associated with formaldehyde, this method of 50 sterilization is no longer considered to be acceptable. If used, the process must be closely monitored, local regulations for hazardous waste disposal must be followed and air sampling for toxic vapours may be indicated. Home microwaves have been shown to inactivate bacteria, viruses, mycobacteria and some spores, however there may not be even 29 distribution of microwave energy over the entire device. More research and testing are required to validate the use of microwave ovens for sterilization. The use of microwave ovens for sterilization of medical 23, 29 equipment/devices is not currently acceptable. A written procedure must be established for the recall and reprocessing of improperly reprocessed medical 1, 2 equipment/devices. All equipment/devices in each processed load must be recorded to enable tracking in the event of a recall. Facilities should consider implementing commercial instrument tracking systems to facilitate identification of patients in the event of a recall. Best Practices for Cleaning, Disinfection and Sterilization in All Health Care Settings | May 2013 49 Health care settings shall have a process for receiving and disseminating medical device alerts and recalls 14 originating from manufacturers or government agencies. Reusable medical devices that have been recalled due to a reprocessing failure shall be reprocessed prior to use. If a failed chemical indicator is found, the contents of the package shall be reprocessed before use. A procedure shall be established for the recall of improperly reprocessed medical equipment/devices. Health care settings shall have a process for receiving and disseminating medical device alerts and recalls originating from manufacturers or government agencies. Single-Use Medical Equipment/Devices Health care settings must not internally reprocess single use medical equipment/devices. Critical and semi critical medical equipment/devices labelled as single-use must not be reprocessed and re-used unless the 51, 52 reprocessing is done by a licensed reprocessor. Health care settings that wish to have their single-use medical equipment/devices reprocessed by a licensed reprocessor should ensure that the reprocessor’s facilities and procedures have been certified by a regulatory authority or an accredited quality system auditor to ensure the cleanliness, sterility, safety and functionality of 53 rd the reprocessed equipment/devices. If a facility enters into a contract with a 3 party reprocessor, the liability for adverse outcomes in the event of improper sterilization, or changes to equipment functionality, must be clear to both parties. In order to have single-use critical or semicritical medical equipment/devices reprocessed by one of these facilities, there must be processes for: tracking and labelling equipment/devices recalling improperly reprocessed medical equipment/devices assuring proof of sterility or high-level disinfection testing for pyrogens maintenance of equipment/device functionality and integrity quality assurance and quality control reporting adverse events provision of good manufacturing procedures. Best Practices for Cleaning, Disinfection and Sterilization in All Health Care Settings | May 2013 50 Single-use medical equipment/devices are usually labelled by the manufacturer with a symbol: Whereas reusable medical equipment/devices are sold with instructions for proper cleaning and sterilization, no such instructions exist for single-use medical equipment/devices. Furthermore, manufacturers often have not provided data to determine whether the equipment/device can be thoroughly cleaned, whether the materials can withstand heat or chemical sterilization, or whether delicate mechanical and electrical components will 51 continue to function after one or more reprocessing cycles. In circumstances where the manufacturer does not approve of reuse, the facility may bear the brunt of legal responsibility in establishing when and under what conditions reuse of medical equipment/devices presents no increased risk to clients/patients/residents and that a reasonable standard of care was adhered to in the reuse of the equipment/device. This would involve written policies, extensive testing of reprocessing protocols and strict adherence to quality assurance investigations.
