Asthma patient education: current utilization in pulmonary training programs

The national guidelines for the diagnosis and management of asthma published in April of 1997 emphasized patient education in asthma management. It is unclear how often patient education is included in asthma management clinics. We sought to determine how often education programs are available by surveying teaching hospitals with training programs in pulmonary and critical care medicine. Using this survey, we also determined the reason programs are not offered and whether computer resources are routinely available to utilize computer-delivered patient educational materials. We sent mail questionnaires to 163 training programs in the United States. We had a response rate of 72% (117 of 163). Of the 117 programs responding, 75 (64%) reported having a formal asthma patient education program. Most (72%) were in university teaching hospitals. A majority of respondents (84%) believed that compensation for their efforts was inadequate, and those hospitals with no formal asthma education program reported that financial cost and time requirements were the primary reasons for not having such a program. Despite the fact that many programs did not have a patient education component, 96% (72 of 75) of respondents with an educational program viewed patient education as an effective patient self-management tool. Of all programs surveyed, 85% reported they would use a high-quality computer-based asthma education program if one was available. Implementation of such a program is feasible, with 69% of programs surveyed having a personal computer in their clinic and 60% having Internet access. We conclude that most training directors believe that patient asthma education is important and effective; however, cost and time issues remain barriers to its implementation. Computer-based educational programs delivered over the Internet are feasible, could address some of these limitations, and are acceptable to most programs.

A model intervention for elder abuse and dementia

This article describes a 2-year collaborative project in Cleveland, OH, that improved the reporting and management of potential and suspected elder abuse situations involving persons with dementia. Educational curricula for cross-training, screening tools, and referral protocols were developed and tested for staff and volunteers in adult protective services and dementia care. A handbook for caregivers of persons with dementia was produced that enables caregivers to self-identify elder abuse risk and seek appropriate interventions to prevent abuse. Project organization, implementation, and evaluation are discussed along with strategies for replication in other communities.

Realizing the promise: delivering pulmonary continuing medical education over the Internet

STUDY OBJECTIVES

Continuing medical education (CME) is meant to bridge the gap between new scientific observations and clinical practice. However, traditional CME has not been effective at altering the behaviors of physicians. One reason for this failure of traditional CME programs may be their inflexibility. In traditional CME, the clinician does not choose the topic, the pace of the program, or the place of learning, and the CME material cannot be easily delivered to the point of care where the clinician needs the information. Computers and computer networks have the potential to accomplish these goals. CME has begun to appear on the Internet; however, there have been few evaluations of its usefulness, acceptance, and effectiveness. Over the last 18 months, we have developed three on-line pulmonary CME programs, and we have delivered them on the Virtual Hospital, the University of Iowa's digital health sciences library on the Internet. We report our initial experience with this CME material.

DESIGN

We measured the frequency with which the Internet-delivered CME is accessed by monitoring page accessions and by using a log file analysis program (Analog 1.2.3; University of Cambridge Statistical Laboratory; Cambridge, UK). In addition, we collected all completed CME examinations and evaluation forms submitted by registered users.

MEASUREMENTS AND RESULTS

We have found that the frequency with which the Internet-delivered CME is accessed has continued to increase with time (2.3-fold increase over 18 months), that evaluations of technical and content issues are strongly favorable, and that some clinicians have been willing to pay to receive CME through the medium of the Internet.

CONCLUSIONS

We feel that with adequate peer review and quality control, physicians will use the Internet-delivered CME. However, several obstacles to wide use remain. These obstacles include issues regarding training in using the Internet for physicians, reluctance of physicians to participate in on-line commerce, and the current unavailability of CME to be delivered in small-grained quantities to the point of care. As these issues are addressed, we feel that on-line CME will represent an increasingly important CME medium for clinicians.

Outcome of the treatment for sarcoidosis

The clinical characteristics and pathology of sarcoidosis are well defined; however, the optimal therapy for this disorder remains unclear. Although patients respond, acutely, to corticosteroid therapy, it is not clear that these agents ultimately alter the natural history of this disease. These observations and that corticosteroids have significant side effects suggest that only patients who will clearly benefit from corticosteroid therapy should be treated. In a prospective study of patients' with sarcoidosis (n = 98), we limited our use of corticosteroids to those patients who had objective evidence of recent deterioration in lung function or serious extrapulmonary disease. All patients with sarcoidosis fulfilling these criteria were treated with corticosteroids. Patients were tapered off corticosteroids after they were treated for 1 yr. Of the 98 study subjects, 91 had not received therapy for the disease and 7 were on therapy before entry into the study. Of the 91 previously untreated patients, 55 were observed without therapy and 36 were treated with corticosteroids. Of those who were observed off therapy, only eight deteriorated. Of these latter patients, six responded and stabilized with the administration of corticosteroids for treatment of the underlying disease, to antibiotics for an associated bronchiectasis, or to diuretics for treatment for congestive heart failure; two were lost to follow-up. None of these six patients deteriorated while receiving corticosteroids. Of the 36 patients who deteriorated and were treated with corticosteroids, 20 remained stable and 16 improved clinically. Of the 37 patients who were eventually tapered off corticosteroids, five deteriorated and required reinitiation of corticosteroid therapy.(ABSTRACT TRUNCATED AT 250 WORDS)

Plasma fibronectin levels during cardiopulmonary bypass

Plasma fibronectin, also called cold-insoluble globulin, is a cryoprecipitable glycoprotein with both opsonic and adhesive activities. It binds to collagen, actin, and heparin and can form soluble as well as cryoprecipitable complexes in the cold. Fibronectin augments particulate phagocytosis by the reticuloendothelial system and can influence lung vascular permeability. Plasma fibronectin deficiency is temporally associated with respiratory failure in septic surgical, trauma, and burn patients. We measured plasma fibronectin and albumin levels in nine adults undergoing elective cardiopulmonary bypass to determine whether dilution alone could account for the changes in plasma fibronectin. Plasma fibronectin concentration decreased 17% with the surgical trauma of opening of the chest and placement of the vascular cannulas. On heparinization and initiation of cardiopulmonary bypass, plasma fibronectin fell an additional 48% (P less than 0.001), whereas albumin concentration (corrected for albumin in the pump prime) fell only 25% (P less than 0.001), emphasizing that dilution was not the only mechanism contributing to the decline in plasma fibronectin. Fibronectin levels began to increase after discontinuation of cardiopulmonary bypass and in association with diuresis, but unexpectedly they remained subnormal until 4 days postoperation. Thus the decline in fibronectin concentration with cardiopulmonary bypass may be due to dilution as well as opsonic consumption and possible complexing with heparin in the cold.

Reversal of opsonic deficiency in surgical, trauma, and burn patients by infusion of purified human plasma fibronectin. Correlation with experimental observations

Plasma fibronectin deficiency has been documented in critically ill surgical, trauma, and burn patients. Human plasma fibronectin was isolated by gelatin-Sepharose affinity chromatography and evaluated with respect to its opsonic activity following pasteurization, its in vivo clearance kinetics, and its short-term influence on cardiovascular hemodynamics in postoperative septic sheep. Six patients with low plasma fibronectin levels were also evaluated with respect to temporal changes of immunoreactive fibronectin and opsonic activity following infusion of fibronectin at a dose calculated to elevate the plasma fibronectin level to 400 micrograms/ml. With utilization of three different in vitro radioisotopic phagocytic assays, i.e., liver slice assay, peritoneal macrophage monolayer assay, and Kupffer cell monolayer assay, retention of opsonic activity by fibronectin following pasteurization was documented. The normal biphasic kinetics associated with plasma clearance of fibronectin were also not altered by pasteurization. In postoperative septic sheep with hemodynamic instability, intravenous infusion of 500 mg of purified human fibronectin initiated no abnormal hemodynamic response. Indeed, as compared with placebo, the infusion of fibronectin into the postoperative septic sheep resulted in a more stable systemic vascular resistance and pulmonary vascular resistance with a higher arterial pressure. It also elevated immunoreactive fibronectin levels (p less than 0.05) and increased opsonic activity (p less than 0.05). Surgical, trauma, and burn patients (ages 18 to 80 years) with low plasma fibronectin levels (160 to 236 micrograms/ml) manifested no disturbance in cardiovascular, respiratory, or hematologic parameters following fibronectin infusion (590 to 988 mg per patient), but did display an early increase of opsonic activity. This standardized, pasteurized, and opsonically active preparation of purified human plasma fibronectin (5.0 mg/ml after reconstitution) has utility for future randomized clinical trials in injured patients with sepsis.
