In reality, there are always a number of barriers to educational events or courses by-theme-initiative/ implementing any programme and these vary depending on the for key staf healthcare-associated- local situation. The table below lists the most Health Education England commonly reported barriers. See chapter 13 for more information on education and competencies, including examples from other countries. Breaking down the view that Sell the benefts, and highlight the stewardship team are the the threats; promote the police and developing co- positive efect on patient operative working to improve outcomes with lack of patient care. The secret of change is to focus all of your energy, not on fghting the old, but on building the new. If youve made it this far in the book, you understand the importance of antimicrobial stewardship: It enhances individual patient outcomes and improves public health. You may be surprised to learn of good work that is already being done at your hospital or clinic. But perhaps with a specifc resource or structural modifcation, even more remarkable things could be accomplished! If so, take heart: that is an opportunity for change, and you may be the one to take the lead. As a rough start, one pharmacist should probably be hired for at least The word resources is often used as a euphemism for money. But, if the level of patient complexity Certainly, funding is an important consideration. Think of resources as human requirements have been recently suggested and provide helpful and technical. Human Resources: Antimicrobial stewardship starts with people: That is why its fun! Human resources estimates and funding for antibiotic stewardship teams are urgently needed Other human resources should be assured. Microbiologists are also important partners, and there should be a plan for robust collaboration between stewardship and the clinical laboratory. Micro lab directors can provide antibiotic resistance data, guide providers at the point of care with savvy messaging, and implement rapid diagnostic testing to facilitate prompt de- escalation of empiric therapy. Nurses and Clinical Ofcers are front-line partners in care, and may have a large impact upon the success or failure of stewardship programs. Understanding their needs and securing their partnership should be a top priority. These activities require expertise, and asking the stewardship leaders to take this on may "Pharmaceutical (296)" fickr photo by Doug Waldron negatively impact their productivity. Finally, is there assistance for the stewards in arranging meetings, Efective stewardship programs are led by pharmacists and tracking projects, and staying organised? Each leaders time assistance can make all the diference between efective should be protected for stewardship activities. In large centres, stewardship may be a full-time job, whereas in smaller hospitals a reduced fraction of efort may be appropriate. The best stewards are clinically active and visible to front-line providers; this earns trust and paves the way for acceptance of their recommendations. But, because clinical medicine requires tremendous time and energy, these questions require clear answers: Will stewardship leaders be paid for their time, or will they have to apply for grants to support their wages? The ideal ratio of stewards to patients is uncertain, and likely depends on the setting (for example, inpatient versus ambulatory). This provides antimicrobial stewards would probably be teamwork, because so many stakeholders with rich opportunities to support decisions in real time, mine are involved. But, only if they have access to the leaders is essential, and both should understand their roles and information. For instance, if the physician thinks of the pharmacist as an assistant or subordinate, then the pharmacists job satisfaction may be reduced. If the pharmacist expects the physician to review every intervention, then progress may be painfully slow. This relationship should be structured in the most equitable and efcient way possible. Will the stewards be nested within the infection prevention team, or will they be considered a separate entity? Will they be held accountable for their work, and if so, what criteria will be used to determine accountability? Hospital executives are important stakeholders, but because stewardship touches so many lives in so many ways, it may be difcult for non-clinicians to grasp the programs tremendous importance. The pharmacist and physician stewardship leaders should know precisely what their supervisors want and expect to "Health and Medical Cloud" fickr photo by perspecphoto88 hear regarding progress and impact. Executive sponsors need to know that they are getting a good return on their investment, so they may focus Does your centre embrace computerised order entry? Is the on cost savings as measured by pharmacy expenditure, days of medical record electronic, and if so is it searchable? These are fne metrics, as described pharmacy database online, and if so can reports be generated below although tracking them can be a chore. If so, does it track are set, the stewards should know what the implications are if antibiotic orders or actual administrations, for instance via they are missed.
Clinical Presentation Patients with this condition will present in a variety of ways (Table 1) order 100mg vermox with amex hiv infection every year. Patients with chronic disease often have other manifestations of their liver disease including jaundice generic 100 mg vermox with amex hiv infection brain, ascites and gastrointestinal bleeding. The usual physical signs and laboratory abnormalities associated with advanced liver disease may be present. These physical findings include muscle wasting, jaundice, peripheral edema, and ascites. Occasionally fetor hepaticus, a sickly-sweet smell from the mercaptanes in the breath, will be present. Hepatic encephalopathy is characterized by changes in personality, consciousness, behavior and neuromuscular function. West Haven Criteria for Hepatic Encephalopathy Stage Consciousness Intellect and Behaviour Neurological findings 0 - Normal - Normal - Normal exam 1 - Mild lack of - Shortened attention span - Mild asterixis or tremor awareness Impaired attention or subtraction 2 - Lethargic - Disoriented - Obvious asterixis - Inappropriate behavior - Slurred speech 3 - Somnolent but - Gross disorientation - Muscular rigidity and clonus arousable - Bizarre behaviour - Hyperreflexia 4 - Coma - Coma - Decerebrate posturing First Principles of Gastroenterology and Hepatology A. The earliest feature is often reversal of the diurnal sleep pattern or subtle personality changes and irritability. Asterixis (asymmetric flapping motions of the outstretched, dorsiflexed hands) can be easily checked in a routine clinical exam. Hepatic encephalopathy associated with acute liver failure has a rapid onset and progression. It is usually complicated with cerebral edema, which can lead to seizures and lateralizing neurologic signs. Occasionally, a refractory pattern emerges leading to debilitating syndromes such as dementia, spastic paresis, cerebellar degeneration and extrapyramidal movement disorders. When approaching a patient with severe liver disease who has an altered level of consciousness or other neurological features, it is important to rule out other causes of changes in mental status and neurologic disease. One may need to distinguish the neurologic changes commonly seen in patients with alcoholic liver disease and Wilson disease. It may reflect either a reversible metabolic encephalopathy, brain atrophy, brain edema or any combination of these conditions. The mechanisms of brain dysfunction in liver failure are not clearly known (Table 3). Encephalopathy probably results from a number of mechanisms that include, in part, one or more toxic products that originate in the gut that are usually metabolized by the liver entering the systemic circulation and reaching the brain. Ammonia derived from colonic bacteria and from deamination of dietary glutamine in the small bowel is absorbed into the portal circulation. The intact liver clears almost all of portal vein ammonia, converting it to glutamine and preventing its entry into the systemic circulation. In severe liver disease, ammonia reaches the systemic circulation because of spontaneously created vascular shunts within and around the hepatocytes and the inability of the liver to metabolize the ammonia. Increased blood-brain barrier permeability likely facilitates the entrance of ammonia and other toxic metabolites into the brain. Another hypothesis proposes that increased levels of short-chain fatty acids and aromatic amino acids associated with decreased levels of branched-chain amino acids cause production of false neurotransmitters. Thus, the synergistic action of ammonia with other toxins likely accounts for many of the abnormalities occurring in liver failure, such as the changes in blood- to-brain transport of neurotransmitter precursors, the metabolism of amino acid neurotransmitters and cerebral glucose oxidation. It is usually based on the clinical impression, but this sometimes makes a definite diagnosis difficult. If the patient is unable to sit forward, then gripping the examiners hand could elicit the same oscillatory movement. Upon examination of the motor system, focal deficits are typically not seen, and should prompt further investigations to search for an alternate diagnosis such as intracranial bleeding or an ischemic event. Unless the liver shows signs of spontaneous recovery, these patients should be considered for urgent orthotopic liver transplantation. Management may include elective ventilation, mannitol infusion and intracranial pressure monitoring. Provision of meticulous medical and nursing care to these confused and often comatose patients is very important for their recovery, and to avoid potential complications. Dehydration, hyponatremia, hypokalemia and alkalosis (often the result of diuretic therapy) should be corrected. Shaffer 541 In conjunction with treating the potential triggering events, the next goal of therapy is to lower the level of neurotoxic substances by emptying nitrogenous wastes from the gut. Often these patients have already lost significant muscle mass, and restricting dietary protein only worsens this problem. A commonly used laxative is lactulose, a synthetic disaccharide that is degraded by intestinal bacteria into lactate and acetate to produce stool acidification and an osmotic diarrhea. The daily dose of lactulose should be titrated to produce two to four soft, acidic (pH<6. For most patients, this will be between 15-30 cc orally once to four times per day. Patients will often complain of an excessively sweet taste, flatulence, diarrhea and cramping as the most common side effects. Overdosing can lead to excessive diarrhea, which can result in fluid and electrolyte depletion. Although lactulose is considered by most to be the mainstay of therapy, randomized controlled studies proving the efficacy are lacking.
Can also be due to a stiff knee Abnormal pelvic rotation: Weakness of hip flexors on the swing side acceleration purchase 100 mg vermox amex hiv infection cycle. If there is a discrepancy then flex both knees to isolate the discrepancy to above or below the knee Apparent leg length discrepancy: measure umbilicus to medial melleolus discount 100 mg vermox free shipping hiv viral infection symptoms. If discrepancy but no real leg length discrepancy then postural cause Palpation: Groin: lumps: hernias, lymph nodes, femoral artery aneurysm pain is not hip pain Check for ilio-tibial band pain over the greater trochanter pain is not hip pain Range of motion: always state start and end: from X to Y degrees (eg adduction from 0 to 30 degrees) Compare sides Thomas test for fixed flexion deformity (ie not full extension): Bring up good leg with hand under the spine. When pelvis starts to flex the bad leg wont be able to remain straight if there is fixed flexion deformity. Patient lies with limb in lateral rotation and leg looks short Location: key issue is disruption of blood flow to the femoral head. If disrupted (via a fracture at or above a basicervical fracture) avascular necrosis Treatment: Operative mostly. Neck of femur: leg externally rotated, dislocation: leg internally rotated (in points out and out point in) Femoral shaft Fracture: Clinical: Mostly young adults. Soft tissue swelling/effusion takes up to a day Always ask about knees: Locking: question carefully to distinguish from pain-induced hamstring spasm Giving way Musculo-skeletal 253 Swelling Function: Difficulty with stairs (going up or down? Look for Bakers cyst protrusion of the synovium into the popliteal fossa Look: Get on bed Swelling Muscle wasting: measure thigh circumference Bony deformity Arthroscopy scars Get them to push their knee down into the bed to test: Extension (fixed flexion deformity) For muscle wasting in vastus medialis Can measure angles with a goniometer Feel: Feel for temperature compared with rest of leg and with other knee Feel for effusion (Meniscal pathology often produces an effusion) Stroke/bulge test Patellar tap Palpate joint line along tibial plateau (watch their face): Tenderness here may indicate a meniscal tear, above or below the joint line the meniscus wont be causing it. If damaged traumatically then urgent surgery (the key knee injury where you wouldnt wait for the swelling to go down before operating) Flex their knee. Measure distance from heel to buttock Poster Cruciate Ligament: o Feet back down on the bed leaving both their knees in 90 flexion. Extending the leg will cause pain/clicking Lateral lemniscus: internally rotate the tibia on the femur, apply varus pressure. Now Push it into Varus, this tests the lateral collateral ligament Lay the leg flat and repeat with the knee in full extension: tests all structures not just the collateral ligaments. If cant then effusion/synovitis Site on edge of bed with legs handing over: Look at the direction that the patellar points in. Have the patient flex and extend at the knee should follow an inverted J course Grind or Friction Test Straighten the leg with your hand over the patella Will cause painful grating if the central portion of the articular cartilage is damaged Patella apprehension test: Press the patella laterally and hold it slightly subluxed Watch the persons face and ask them to flex their knee If they grimace or show signs of pain then the test is positive and is diagnostic of recurrent patellar subluxation or dislocation. Check the Hip (pain is referred to the knee from there) Check the Ankle and the foot pulses, and distal neurology Knee Injury General principles of ligament injury: Pain + slight joint opening good (strain/partial rupture) No pain + big joint opening bad (complete rupture) Always x-ray adequately. Aim is to preserve as much of the meniscus as possible Lateral/Medial Collateral Ligament: Most common knee ligament injury Medial is attached to the medial meniscus. But if it is, consider check for fibular head fracture and common peroneal nerve damage Mechanical: Blow to medial/lateral side of knee pushing the joint into varus/valgus Presentation: Tenderness over ligament (unless complete rupture no pain), pain worse under varus/valgus stress, effusion Management: Isolated tears heal well without operating. May have ongoing instability Anterior Cruciate Ligament: Prevents posterior displacement of the femur on the tibia and hyperextension. Quads exercises decrease backwards tibial sag Patella Fractures: Comminuted: from blow to flexed knee (eg knee against dashboard). Put patella together (usually hard) or remove it (patellaectomy) Stellate: blow to patella that cracks but doesnt displace fragments. Patellar aching after prolonged sitting due to softening or fibrillation of the patellar articular cartilage. Conservative treatment: vastus medialis strengthening Disruption of extensor mechanism: Rupture of Rectus Femoris: sudden violent contraction transverse tear. Conservative treatment: ice, elevation, analgesia, mobilisation within limits of comfort. Functional deficit negligible Ruptured Quadriceps tendon: sudden violent contraction. Repair if weakness or extensor lag Dislocation of the Patella: Sharp twisting motion on flexed knee or blow to side of leg haemarthrosis ( swelling) and medial tenderness (medial structures torn). Primary concern is distal circulation reduce at scene of injury if possible Aspirate and irrigate if necessary, splint for 4 weeks Physio to strengthen quads (necessary for patella stability) If recurrent then? Most common with patellar dislocation Haemarthrosis and fat from cancellous bone causing a fat-fluid line on lateral radiograph If small then remove, if large then reattach Chondral separations or flaps: Fragments of articular cartilage. Due to imbalance of extensors and flexors (eg previous polio) Crowding of the toes: rheumatoid arthritis Sausage deformity of the toes: psoriasis, ankylosing spondylitis and Reiters disease Inspect transverse and longitudinal arch: Pes Planus: Flat feet. Need to assess circulation and sensation in toes Treatment: Closed fractures need to be observed for compartment syndrome and soft tissue damage. Obtain fracture alignment and start weight bearing early Open fractures require immediate antibiotics, debridement, then stabilization and rehab Distal fibial fracture: Check even, clear joint space around the ankle Check ankle joint is not subluxed Check ligaments on the other side (eg Deltoid). If damaged unstable Classified as A, B, C1 or C2 If stable, cast for symptomatic relief for 6 weeks Diastasis: = Dislocation where no true joint exists Musculo-skeletal 257 Separation of the distal tibia and fibula. Leads to incongruity of the tibial-talus joint Ruptured deltoid: always exclude proximal fibular fracture (Maisoneuve Fracture) Dislocation of the ankle: reduce urgently (ie before lengthy transport) otherwise ischaemia of overlying skin Achilles Tendon Rupture: Mechanism: Forced dorsiflexion against resistance (eg jumping, due to a forward lunge in squash) an eccentric injury Presentation: Lie on stomach with foot over end of the bed. Foot doesnt move when calf is squeezed Management: Hold the ends together until healed either surgical or conservative. Pain or abnormal movement indicates a fracture Treatment: Dislocated or displaced fractures of the nasal bones need to be repositioned accurately. May require fixation with wires or external fixation Orbital Fractures If direct trauma to the orbit or eye, look for orbital fracture Diplopia and the abnormal position of the eye should lead to the diagnosis Treatment: Surgery th th 258 4 and 5 Year Notes Maxilla Le Fort classification of maxillary fractures: 1: through the maxilla, leaving nose and orbits intact 2: through the maxilla, into the orbit and across the nose leaving the lateral side of the face mobile 3: same as 2 but fracture extends through the lateral wall of the orbit and across the nose All maxillary fractures are an emergency because the lateral wall of the face may be unstable and can fall backwards to obstruct the airway. Neonates consider S agalactiae, Haemophilus and N gonorrhoea (did they have bacterial conjunctivitis soon after birth? X- ray shows marginal erosions and destruction of sub-chondral bone (like Rheumatoid but different distribution). Adjacent joints sore but some movement still possible Vascular supply to bone is compromised and infection spreads to surrounding soft tissue Differential diagnosis: Septic arthritis Cellulitis Trauma (Facture) Tumour Aetiology: Trauma/surgery direct introduction of bacteria Direct extension from infective site: eg dental infection jaw, diabetic foot bones of foot Haematogenous seeding: Commonest site in children is metaphysis of the long bones. Epiphyseal growth plate acts as a barrier to the spread of infection to the joint. May spread through Haversian and Volkmanns canal system to form a subperiosteal abscess (requires drainage) In adults, haematological spread less common. Also cancellous bone of vertebral bodies, may compression fracture Eg: sluggish blood flow easy thrombosis following trauma predisposes to infection (esp staph aureus) Pathology: Inflammatory response oedema compromise vascular supply necrosis spread of infection through cortices pus under periosteum shearing of periosteum further disruption to blood vessels Causative organisms: Under one year: staph aureus, strep agalactiae, E coli.
