Educational outreach in diabetes to encourage practice nurses to use primary care hypertension and hyperlipidaemia guidelines (EDEN): a randomized controlled trial.

OBJECTIVE: To determine the effectiveness of specialist nurse delivered education in primary care to improve control of hypertension and hyperlipidaemia in patients with diabetes. DESIGN AND SETTING: Practice-level randomized controlled trial, Salford, England. SUBJECTS: From 44 practices, 10 303 subjects presenting in general practice with raised blood pressure (= 140/80 mmHg), raised total cholesterol (= 5.0 mmol/l) or both. INTERVENTIONS: Practices were randomized to receive either the intervention for hyperlipidaemia or for hypertension; practices acted as control for the intervention not received. Specialist nurses arranged a schedule of visits with general practitioners and general practice nurses, reminding them of diabetes protocols and clinical targets. They provided educational materials and protocols used in secondary care for nurse and doctor interventions including stepping up pharmacotherapy when necessary. Practices received a list of patients in their practice who were poorly controlled at their last annual review; new and recalled patients were targeted. OUTCOME MEASURES: At subsequent annual review, blood pressure and total cholesterol values were obtained from the Salford electronic diabetes register for patients from participating practices. RESULTS: Overall, specialist nurse-led educational outreach to primary care was associated with no improvement in patients achieving target after 1 year-odds ratio (OR): 1.03 (95% CI 0.95-1.11; P = 0.52). Similar results were achieved with hyperlipidaemia OR: 1.04 (95% CI 0.88-1.23; P = 0.62) and hypertension OR: 1.01 (95% CI 0.80-1.27; P = 0.93). CONCLUSION: This study provides evidence that the use of specialist nurses to perform educational outreach to improve target adherence to patients with diabetes in primary care is not effective.

Interventions for improving information management in family practice.

Information management training has been neglected in family practice in the UK in the past. An adult learning model for such training is introduced. A pilot study using the adult learning approach showed improvements in information management processes over the six-month study period. The research project described in this paper compares the effectiveness of on-site training using adult learning methods, written information, and no intervention, in 33 family practices in the UK. Nine of the eleven practices in the on-site training group completed the training sessions and provided data, whereas only four of the eleven practices in the written information group provided data, and only three of the eleven practices in the control group did so. Preliminary analysis demonstrates that on-site training practices made considerable changes to the information systems in their practices, and appreciated the importance of high-quality data, both for patient care and reporting requirements. Full comparisons of data quality and information management methods are presented, and an assessment of priority training needs for maximum benefit is made.

Improving information management in family practice: testing an adult learning model.

Information management training has been neglected in family practice in the UK in the past. An adult learning model for such training is introduced. A pilot study using the adult learning approach showed improvements in information management processes over the six-month study period. The research project described in this paper compares the effectiveness of on-site training using adult learning methods, written information, and no intervention, in 33 family practices in the UK. Nine of the eleven practices in the on-site training group completed the training sessions and eight provided full data, whereas only one of the eleven practices in the written information group, and only one of the eleven practices in the control group provided full data. Preliminary analysis demonstrates that on-site training practices made considerable changes to the information systems in their practices, and appreciated the importance of high-quality data, both for patient care and reporting requirements. Full comparisons of data quality and information management methods are presented, and an assessment of priority training needs for maximum benefit is made.

Changing patterns of intra-aortic balloon pump assistance.

Intra-aortic balloon pump assistance (IABPA) for cardiogenic shock is well established. The response to balloon pumping and patient survival are better after low output from cardiotomy than after myocardial infarction. Elective use of IABPA preoperatively allows an extra margin of safety for patients with acute coronary insufficiency, significant left main coronary artery stenosis, or depressed left ventricular function. However, advances in monitoring techniques during the induction of anesthesia and weaning from cardiopulmonary bypass support, as well as improved methods for myocardial preservation, have reduced the requirements for elective IABPA. Current indications for preoperative IABPA include: patients with acute coronary insufficiency who are totally unresponsive to full medical management and who continue to have pain and electrocardiographic changes at rest, and patients with serious left main coronary artery stenosis who also have acute coronary insufficiency or depressed left ventricular function. The survival of patients with valvular heart disease and left ventricular dysfunction is not improved with preoperative IABPA, while most patients with depressed left ventricular function from coronary artery disease may now undergo revascularization uneventfully, although inevitably some will still require postoperative IABPA.

Optimal myocardial protection.

The low mortality and perioperative infarction rates for aortocoronary bypass (ACB) make them unsuitable for evaluating the adequacy of myocardial protection. Enzymatic and functional measurements were found to be sensitive and specific indicators of myocardial injury. A prospective concurrent study of 78 patients undergoing triple ACB was conducted to evaluate the effectiveness of three popular methods of myocardial protection. Group I (32 patients) had a single dose of cold (4 degrees C) potassium cardioplegic (CPC) solution infused inducing a mean myocardial temperature (MMT) of 31 +/- 4 degrees C/min. Group II (23 patients) had multiple doses of CPC solution 8nducing a MMT of 22 +/- 2 degrees C/min. Group III (23 patients) had intermittent anoxic arrest at a MMT of 28 +/- 1 degrees C. The groups were not randomized but had comparable clinical symptoms and catheterization findings. Serial measurements of cardiac specific creatine kinase (CK-MB) revealed a peak in enzymatic activity occurring 60 minutes following ACB. The highest CK-MB was significantly (P less than 0.01) lower in group II (25 +/- 8 IU/liter) than group I (50 +/- 8 IU/liter), or group III (68 +/- 14 IU/liter). Myocardial performance was evaluated after ACB by serially measuring left ventricular stroke work index (SW) and left atrial pressure (LAP) in response to volume loading. The rise in SW was significantly (P less than 0.01) greater in group II (3.0 +/- 0.7 gm.m/sq m/mm Hg) than in group I (1.4 +/- 0.7) or group III (1.8 +/- 0.9). The highest SW attained was higher (P less than .01) in group II (43 +/- 7 gm.m/sq m) than group I (19 +/- 6) or group III (34 +/- 8) at comparable LAP values (group I: 20 +/- 5 mm Hg; group II: 18 +/- 3; group III: 18 +/- 4). Post-operative clinical evaluation failed to differentiate among the three groups. The more sensitive indices, however, demonstrated the superiority of cold, multidose cardioplegia in providing optimal myocardial protection.

Combination of membrane oxygenator support and pulmonary lavage for acute respiratory failure.

A 24-year-old woman with chronic granulocytic leukemia and alveolar proteinosis required extracorporeal membrane oxygenator support for respiratory failure refractory to conventional therapy. During perfusion, each lung was lavaged with 10 L. of normal saline. The lavage led to marked clearing of the lungs and improvement in pulmonary function. Extracorporeal support was terminated successfully after 54 hours. The patient died 2 weeks later with bone marrow insufficiency and overwhelming sepsis. Pulmonary lavage is technically feasible during venovenous oxygenator bypass, and may be of value, since such lavage debrides alveoli as well as the bronchial tree. Because pulmonary lavage provides a possible means of improving pulmonary function, it seems worthy of consideration as an adjunct to membrane oxygenator support.

Cardiorespiratory failure secondary to peripheral pulmonary emboli. Survival following a combination of prolonged extracorporeal membrane oxygenator support and pulmonary embolectomy.

A 19-year-old woman developed cardiorespiratory failure from multiple, peripheral pulmonary emboli apparently developing over the preceding 3 weeks. She was not considered to be an operative candidate. However, when 3 days of intravenous heparin infusion and 30 hours of membrane oxygenator support failed to improve the pulmonary pathology, pulmonary embolectomy was performed. The membrane oxygenator support had to be continued for 34 hours following the operation before it was successfully discontinued. The patient made a complete recovery.
