Learning style theories: matching preceptors, learners, and teaching strategies in the perioperative setting.

Individuals have unique learning styles that develop in childhood and remain constant throughout adulthood. One approach to orienting and training staff and students is to match individuals with a preceptor with a similar learning style. Benefits of matching learning styles and using appropriate teaching strategies for each learning style include decreased anxiety and increased staff and student satisfaction. This is a US government work. There are no restrictions on its use.

Responses of lactating dairy cows to copper source, supplementation rate, and dietary antagonist (iron).

Forty-eight lactating Holstein cows were fed low-Cu diets with 500 mg of supplemental Fe/kg of dry matter (DM), a Cu antagonist, for a 30-d Cu-depletion period. After depletion, two Fe treatments (0 and 500 mg of Fe/kg of dietary DM) and five Cu treatments (2 x 5 factorial arrangement) were compared over 83 d. The Cu treatments were control (basal diet containing 8 mg of Cu/kg of DM) and either 15 or 30 mg of supplemental Cu/kg of dietary DM from either CuSO4 or Cu-lysine. Feeding 500 mg of supplemental Fe/kg of DM (in addition to basal dietary concentration of 140 mg Fe/kg) depressed liver Cu in the absence of Cu supplementation. Apparent Cu retention, estimated from Cu intake minus fecal Cu, was increased greatly by Cu supplementation immediately after the depletion period but declined to very low net retention by d 45 of the 83-d experiment. There were no differences detected between CuSO4 and Cu-lysine except a tendency over time for Cu-lysine to maintain higher plasma Cu, especially in the absence of the Fe antagonist.

Measurement of user performance and attitudes assists the initial design of a computer user display and orientation method.

OBJECTIVE: The objective of our study was to assess the acceptability of a proposed user interface to visually interfaced computer-assisted anesthesia record (VISI-CAARE), before the application was begun. The user interface was defined as the user display and its user orientation methods. METHODS: We designed methods to measure user performance and attitude toward two different anesthesia record procedures: (1) the traditional pen and paper anesthetic record procedure of our hospital, and (2) VISI-CAARE. Performance measurements included the reaction speed (identifying the type and time of an event) and completion speed (describing the event). Performance also included accuracy of the recorded time of the event and accuracy of the description. User attitude was measured by (1) the physician's rating on a scale of 0 to 9 of the potential usefulness of computers in anesthesia care; (2) willingness to use the future application in the clinical environment; and (3) user suggestions for change. These measurements were used in a randomized trial of 21 physicians, of which data from 20 were available. RESULTS: After exposure to VISI-CAARE, the experimental subjects' ranking of computer usefulness in anesthesia care improved significantly (4.2 +/- 1.1 to 7.6 +/- 1.5, p = 0.0001), as did controls' (5.2 +/- 2.6 to 8 +/- 1.5, p = 0.0019). All the volunteers were willing to try the proposed prototype clinically, when it was ready. VISI-CAARE exposure was associated with faster and more accurate reaction to events over the traditional pen and paper machine, and slower and more accurate description of events in an artificial mock setting. VISI-CAARE 1.1 demonstrated significant improvements in both reaction speed and completion speed over VISI-CAARE 1.0, after changes were made to the user display and orientation methods. CONCLUSION: With graphic user interface prototyping environments, one can obtain preliminary user attitude and performance data, even before application programming is begun. This may be helpful in revising initial display and orientation methods, while obtaining user interest and commitment before actual programming and clinical testing.

Development of a case management plan for aortoiliac bypass graft surgery patients.

Case management can reduce health care costs of the aortoiliac bypass graft surgery patient by eliminating unnecessary services, preventing duplication of services, and preventing costly readmissions in high-risk patients. This can be achieved through use of a case management plan that incorporates critical pathways, perioperative clinical nurse specialists as nurse case managers, ad hoc group practices, and patient and family participation.

Post-traumatic upper airway obstruction secondary to a lingual artery hematoma.

An accident victim presented with maxillofacial trauma complicating a head injury. After the airway was secured by tracheostomy, surgical exploration revealed a lingual artery hematoma. This case illustrates the progressive airway occlusion seen with this disorder and the importance of repeated oral examinations.

Medical information management: improving the transfer of research results to presurgical evaluation.

We designed a medical information management (MIM) system to 1) identify high-risk patients (with cardiopulmonary dysfunction or undergoing major surgery), and 2) augment traditional mechanisms for referring high-risk patients to respiratory specialists. We define MIM as the combination of techniques that solicit, record, transfer, analyze, and distribute patient data according to designated protocols. A randomized trial compared 247 control subjects with 272 surgical patients assisted by information management. Data analysis focused on patients with cardiopulmonary impairment. The results showed that the MIM assisted patients received (1) more preoperative respiratory assessments (83.2 per cent vs. 9.2 per cent) than controls, 2) more preoperative respiratory therapy (37.9 per cent vs. 8.0 per cent) and 3) fewer postoperative respiratory complications (8.4 per cent vs. 16.1 per cent) than controls. These findings suggest that a MIM system can be an effective auxiliary mechanism for improving presurgical care.

Use of a computerized respiratory care record system to study utilization of IPPB therapy.

Increases in the utilization of respiratory therapy and the need to avoid its misuse have placed increasing management responsibilities on medical and technical supervisors of respiratory care services. To improve our managerial capabilities we designed a computerized respiratory care record system. Respiratory therapists use specially designed forms to record initial respiratory assessments and subsequent progress notes. A computer program allows secretaries to enter information from the forms into a data base. Another program tabulates information from the data base. As an example of the usefulness of this system we present a study of the utilization of intermittent positive-pressure breathing (IPPB) therapy in patients undergoing intrathoracic or upper abdominal surgery. Although all such patients were routinely educated preoperatively in the use of IPPB, chest physiotherapy, and incentive spirometry, the study revealed that only 14% of the patients received IPPB postoperatively, whereas more than 90% received chest physiotherapy and incentive spirometry. As a result of our findings we are saving time and money by discontinuing routine IPPB education for this population.

Computer assisted patient evaluation (CAPE): a multi-purpose computer system for an anesthesia service.

We have designed and built a database management system, the computer assisted patient evaluation (CAPE) system, for use in patient management, research, and administration in our anesthesia practice. An important part of the system is the use of specially designed forms on which anesthesiologists record patient histories and management information during the course of patient care. The forms provide means for convenient and complete record keeping, as well as for direct computerization. We demonstrate the flexibility and utility of the CAPE system by presenting a series of examples of its use. These include development and implementation of a preoperative screening program to identify patients at high risk of postoperative respiratory complications; a study of anesthesia technique and outcome; auditing for quality of care; and utilization review of respiratory therapy.
