Expanding the enablement framework and testing an evaluative instrument for diabetes patient education.

BACKGROUND: Strategies to delay or prevent complications from diabetes include diabetes patient education. Diabetes educators seek to provide education that meets the needs of clients and influences positive health outcomes. AIMS: (1) To expand prior research exploring an enablement framework for patient education by examining perceptions of patient education by persons with diabetes and (2) to test the mastery of stress instrument (MSI) as a potential evaluative instrument for patient education. METHOD: Triangulated data collection with a convenience sample of adults taking diabetes education classes. Half the sample completed audio-taped semi-structured interviews pre, during and posteducation and all completed the MSI posteducation. Qualitative data were analysed using latent content analysis, descriptive statistics were completed. RESULTS: Qualitative analysis revealed content categories similar to previous work with prenatal participants, supporting the enablement framework. Statistical analyses noted congruence with psychometric findings from development of MSI; secondary qualitative analyses revealed congruency between MSI scores and patient perceptions. CONCLUSIONS: Mastery is an outcome congruent with the enablement framework for patient education across content areas. Mastery of stress instrument may be a instrument for identification of patients who are coping well with diabetes self-management, as well as those who are not and who require further nursing interventions.

Single-blind, prospective, randomized study of cefmetazole and cefoxitin in the treatment of postcesarean endometritis.

OBJECTIVE: The purpose of this study was to compare the clinical efficacy and safety of cefmetazole given by IV push with that of parenterally administered cefoxitin for the treatment of endometritis following cesarean delivery. METHODS: In a single-blind, multicenter, prospective, randomized study, 355 patients with endometritis after cesarean delivery were enrolled and received medication. Administered was either cefmetazole sodium, 2 g by IV push over 1 min q 8 h, or cefoxitin sodium, 2 g IV q 6 h in a 2:1 ratio. The patients were followed for clinical responses and side effects. RESULTS: The cure rate for cefmetazole was 89% and for cefoxitin it was 79% (P = 0.006). The adverse events were similar in both groups. CONCLUSIONS: Cefmetazole was significantly more effective than cefoxitin in the treatment of endometritis following cesarean delivery.

Hypertension in diabetic clinic patients and their siblings.

The prevalence of hypertension was investigated in a systematically chosen sample of patients attending a diabetic clinic. One hundred ninety-one patients were classified as Type 1 (insulin-dependent), 183 were classified as Type 2 (non-insulin-dependent) and 12 were deemed unclassifiable. Two hundred fifty-five control subjects attending non-medical out-patient clinics were also examined under similar conditions. Hypertension was significantly (p less than 0.001) more common among Type 2 patients (38%) than among Type 1 patients (15%) or control subjects (16%). The difference between Type 2 patients and control subjects, but not between Type 2 and Type 1 patients, persisted when the influences of age and body mass index were controlled. We also investigated the prevalence of hypertension among the siblings of the hypertensive patients identified, together with a matched normotensive group. One hundred eighty-eight siblings were examined and historical details were obtained for a further 451 siblings. When age and body mass index were controlled for in examined siblings, the risk of hypertension was greater in those with a hypertensive proband than in those with a normotensive proband, in the control (p less than 0.06) and Type 1 (p less than 0.02) groups.(ABSTRACT TRUNCATED AT 250 WORDS)

Diabetic control and the renin-angiotensin system, catecholamines, and blood pressure.

Diabetic ketoacidosis is usually associated with marked secondary hyperaldosteronism. Plasma levels of renin, angiotensin II, and aldosterone are markedly raised before treatment in most patients, with values falling rapidly toward normal as metabolic control is restored. In a few patients, mostly those with long-term complications of diabetes, plasma levels of renin, angiotensin II, and aldosterone before treatment remain within the normal range. In moderately hyperglycemic patients who have glycosuria but not ketonuria, plasma levels of all three substances are significantly higher than when control is improved. Occasionally, moderately hyperglycemic patients have mild secondary hyperaldosteronism. Improved metabolic control in such patients causes a rise in plasma volume and a rise in total exchangeable sodium, the latter to levels significantly above normal. Plasma catecholamine levels are markedly elevated in diabetic ketoacidosis, probably as a consequence of the ketoacidotic state. In nonketotic patients with moderate hyperglycemia, basal plasma norepinephrine levels are normal; catecholamine responses to exercise may be exaggerated, however. Epidemiological and animal studies suggest a relationship between blood pressure and blood glucose levels. There are few clinical studies of the effects of altering metabolic control of diabetes on blood pressure, and this is an important area for further study.
