In 1957, the ﬁrst American research fellow began work in Professor Hirsch’s biomechanics laboratory. Thereafter, each year one or two research fellows from the United States and other parts of the world spent a year or two in the bio- 141 Who’s Who in Orthopedics mechanics laboratory under his direction, per- Carl Hirsch was known to all by his Swedish forming research and learning the application of nickname, “Calle. In exchange fellows from overseas and for all visit- Sweden, it is common for a physician aspiring to ing orthopedic surgeons. It was a rare visitor to an academic position to perform research and his clinic in Uppsala, Göteborg, or Stockholm then to write a thesis to attain the advanced degree who was not brought to the Hirsch’s home, which of Med Dr. After the thesis has been written and was ﬁlled with modern Swedish paintings and submitted to the university, the candidate must sculpture, for a typical Swedish meal. These defend the work publicly before a panel of three activities were presided over by his ﬁrst wife, experts. She was a woman of is then usually published as a supplement to great warmth, and through her hospitality she did Acta Orthopedica Scandinavica. The inﬂuence of much to make the families of the research fellows a medical educator on the next generation of from overseas feel at home and comfortable in a medical educators in Sweden can thus be meas- new environment. During the period from Carl had a great facility for making friends, 1960 to 1973, 40 doctoral theses were produced which made it easy for his students to develop a under the direction of Carl Hirsch, seven by close relationship with him. In 1971, the Carl orthopedic surgeons spent shorter periods of time Hirsch Föreningen, a society of former American in his biomechanics laboratory. Carl States and was usually to be found at the annual Hirsch died on June 19, 1973, at the age of 60. An academic career requires a nice balance between patient care, research, and education. It is rare to ﬁnd capabilities in all three areas com- bined in one man. In the area of research, the 40 doctoral theses attest to his ability as a researcher and research director. He established an excellent biomechanics laboratory, which has served as a model for many others throughout the world. He had the ability to pose a problem to a person and then gently to lead, push, and encourage that person to completion of the work. In the area of medical education, he played an important role in Sweden, acting as an advisor to the Swedish gov- ernment in the ﬁeld of orthopedic surgery and rehabilitation. He was a corresponding member Arthur Ralph HODGSON of the American Orthopedic Association and an honorary member of the American Academy of 1915–1993 Orthopedic Surgeons, the Shriners, and the Israeli Orthopedic Association. He was also a member of Arthur Ralph Hodgson was born in Uruguay to the French, British, and Swiss Associations, and British parents. He was schooled at home by was active in the Société Internationale de his mother. He received his medical education Chirurgie Orthopédique et de Traumatologie. Like all of his generation, Hodgson went into the army and served in India, Burma, and Singapore. At the time of his discharge at the end of World War II, Hodgson was a Lieutenant Colonel. After his discharge, Hodgson returned to England for additional training. In 1951, Hodgson was appointed senior lec- turer and head of the Orthopedic and Trauma Unit in the Department of Surgery at the University of Hong Kong. It was here that he began his impor- tant work on the treatment of tuberculosis of the spine. The large number of patients and the lack of facilities for long-term conservative treatment made a more aggressive approach necessary and led Hodgson to seek a more radical surgical solu- tion to the problem. He accomplished this by exploiting the anterior approach to the spine with drainage of the abscess, removal of sequestrae, Albert HOFFA and correction of the deformity.
This is the basic principle underlying the development of objective structured clinical examinations (OSCEs) purchase line xalatan medications list form. Several other structured clinical examinations have been developed in recent years generic xalatan 2.5 ml on line symptoms miscarriage, including Written tests can assess knowledge acquisition and reasoning ability purchase xalatan 2.5 ml amex symptoms 1974, but they modified OSCEs—such as the Royal College of Physicians’ cannot so easily measure skills Practical Assessment of Clinical Examination Skills (PACES) and the objective structured long case (OSLER). This article focuses mainly on OSCEs to illustrate the principles of skill based assessment. OSCEs The objective structured clinical examination (OSCE) was introduced over 30 years ago as a reliable approach to assessing basic clinical skills. It is a flexible test format based on a circuit of patient based “stations. Standardised patients are lay people trained to present patient problems realistically. The validity of interactions with real patients, however, may be higher than that with standardised patients, but standardised patients are particularly valuable when communication skills are being tested. OSCE stations may be short (for eample, five minutes) or Patient-doctor interaction for assessing clinical performance long (15-30 minutes). Scoring is done with a task specific checklist or a combination of checklist and rating scale. The scoring of the students or trainees may be done by observers (for example, faculty members) or patients and standardised patients. Design The design of an OSCE is usually the result of a compromise between the assessment objectives and logistical constraints; however, the content should always be linked to the curriculum, What skills should trainees have acquired as this link is essential for validity. Using many short stations should generate scores that are sufficiently reliable for making pass-fail decisions within a reasonable testing time. The number of students, time factors, and the availability of appropriate space must also be considered. Questions to answer when designing an OSCE 32 Skill based assessment Planning Planning is critical. Patients and standardised patients can be Tasks to do ahead recruited only after stations are written. Checklists must be reviewed before being printed, and their format must be x Create blueprint x Set timeline (how long do we need? The result is increased cost x Print marking sheets, make signs and wasted time. Several x Plans for the examination day: diagram of station layout; directions methods for setting standards have been used, with the Angoff for examiners, standardised patients, and staff; possible registration method described below being the most commonly used. Costs OSCE costs vary greatly because the number of stations determines the number of standardised patients, examiners, and staff required. Whether or not faculty members volunteer to write cases, set standards, and examine is also a significant The fixed costs of running an OSCE factor. Developing the stations Administering an OSCE twice in one day OSCE stations have three components. The stem must clearly state the task—for example, “in the next eight minutes, conduct a relevant physical examination. These items should be In the next eight minutes, conduct a relevant physical examination reviewed and edited to ensure that (a) they are appropriate for the level of training being assessed, (b) they are task based, and (c) they are observable (so the observer can score them). The length of the checklist depends on the clinical task, the Checklist Examiner to fill in box for each item that trainee successfully completes time allowed, and who is scoring. A checklist for a five minute Marks station that is testing history taking may have up to 25 items if a ❑ Drapes patient appropriately 2 faculty observer is doing the scoring. If a patient or standardised ❑ Inspects abdomen 1 patient is doing the scoring, then fewer items should be used.

If I went into the bathroom, I just had time to wash my hands and hobble back to the bed. If I was in there to go to the bathroom, I could never stay long enough to brush my teeth. People with arthritis often describe immobilizing and painful stiffness, especially on awaking in the morning or after prolonged sitting. Like the tin woodsman from The Wizard of Oz after a rainfall, they feel rusted in place, painfully unable to ﬂex, bend, or move. Jimmy Howard, in his late forties, feels “like somebody’s in there with a hammer and a chisel, just chiseling away. Then one day I was walking, and, whoa, it really started—excruciat- ing pain. I’d be in the supermarket, and I’d have to grab onto peo- ple I don’t know. If I tell them to help me, and my knee’s still locked, I can’t go no place. Cynthia Walker, in her mid thirties, has two children under ﬁve years old. Her rheumatoid arthritis primarily affects her ankles, knees, and wrists. With rheumatoid arthritis, when you’re immobile, when you lie on the couch, on a bed, your joints are very relaxed. You really have to put pressure on the ﬂoor for quite a while for your joints to hold your weight, to put one foot in front of the other, and sometimes you just can’t stand up anymore. If a child yells for you or you need to be somewhere fast, it’s a problem.... And the child is screaming, and the crutches are upstairs because you left them upstairs that morning. You want to get just two rooms over, but that two rooms might as well be two miles. My knees don’t work, and if I get down on the ﬂoor, how the hell am I going to get back up? They also attempt steroid injections, acupuncture, heating pads or cold compresses, pool therapy, massage, and prayer. Some- times physicians explicitly say they can do nothing more for the pain, leav- ing people angry, frustrated, and disheartened (chapter 8). Nevertheless, most people say they are stoic, refusing to “give in” to pain. Despite her older children’s protests, Mattie Harris sweeps her kitchen ﬂoor when it’s dirty; she can’t “sit there and see something that needs to be done. Even those with self-described high pain thresholds may eventually try surgery Sensations of Walking / 29 in an attempt—sometimes successful, sometimes not—to eliminate pain and restore function. Mike Campbell Mike Campbell, a retired maintenance man in his mid sixties, had os- teoarthritis of both knees. He and his wife, Betty, occupied an in-law apart- ment upstairs in their daughter’s home outside a New England picture postcard town. We met on a perfect autumn day, crimson and golden leaves swirling in the wind, pumpkins on every stoop. The air smelled wonderful and woodsy when I and Ron, my administrative assistant and driver, emerged from the car onto a bed of needles from towering pine trees. From the driveway, we saw only the side of the house, with steep, wooden stairs leading to a second ﬂoor door. Ron reported that we were meeting in the daughter’s living room downstairs. Campbell, a big man, ruddy in a hale and hearty way, sat in a wing- back chair at one end of an immaculate living room dotted with china ﬁg- urines. Having had his second knee replaced several weeks previously, he had crutches propped against the wall, and his left knee appeared thickly padded. Campbell had not planned on retiring from building maintenance two years previously.
Short answer order genuine xalatan on-line medicine 4211 v, open ended that this assumed superiority is limited questions are not suitable for assessing factual knowledge; use multiple choice questions instead buy on line xalatan symptoms stomach ulcer. Short answer buy line xalatan nail treatment, open ended questions should be aimed at the aspects of competence that cannot be tested in any other way. Essays Essays are ideal for assessing how well students can summarise, hypothesise, find relations, and apply known procedures to new situations. They can also provide an insight into different aspects of writing ability and the ability to process information. Unfortunately, answering them is time consuming, so their reliability is limited. When constructing essay questions, it is essential to define the criteria on which the answers will be judged. A common pitfall is to “over-structure” these criteria in the pursuit of objectivity, and this often leads to trivialising the questions. Some structure and criteria are necessary, but too detailed a structure provides little gain in reliability and a considerable loss of validity. Essays involve high costs, so they should be used sparsely and only in cases where short answer, open ended questions or multiple choice questions are not appropriate. Key losing too much reliability feature questions seem to measure problem solving ability 30 Written assessment validly and have good reliability.
