'It just has to click':Internists' views of: what constitutes productive interactions with chronically ill patients

Background: According to the Chronic Care Model, productive interactions are crucial to patient outcomes. Despite productive interactions being at the heart of the Model, however, it is unclear what constitutes such an interaction. The aim of this study was to gain a better understanding of physician views of productive interactions with the chronically ill. Method: We conducted a qualitative study and interviewed 20 internists working in an academic hospital. The data were analyzed using a constructivist approach of grounded theory. To categorize the data, a coding process within which a code list was developed and tested with two other coders was conducted. Results: The participants engaged in goal-directed reasoning when reflecting on productive interactions. This resulted in the identification of four goal orientations: (a) health outcome; (b) satisfaction; (c) medical process; and (d) collaboration. Collaboration appeared to be conditional for reaching medical process goals and ultimately health outcome and satisfaction goals. Achieving rapport with the patient ('clicking,' in the term of the participants) was found to be a key condition that catalyzed collaboration goals. Clicking appeared to be seen as a somewhat unpredictable phenomenon that might or might not emerge, which one had to accept and work with. Goal orientations were found to be related to the specific medical context (i.e., a participant's subspecialty and the nature of a patient's complaint). Conclusions: The participants viewed a productive interaction as essentially goal-directed, catalyzed by the two parties clicking, and dependent on the nature of a patient's complaint. Using the findings, we developed a conceptual process model with the four goal orientations as wheels and with clicking in the center as a flywheel. Because clicking was viewed as important, but somewhat unpredictable, teaching physicians how to click, while taking account of the medical context, may warrant greater attention

The relationship between glycaemic control and mortality in patients with type 2 diabetes in general practice (ZODIAC-11)

Background The relationship between the degree of glycaemic control and mortality remains an important topic of discussion.Aim This study aimed to investigate this relationship.Design of study Prospective cohort study.Setting Primary care.Method A total of 1145 patients with type 2 diabetes were enrolled in the Zwolle Outpatient Diabetes project Integrating Available Care (ZODIAC) in 1998. Their survival status was recorded in September 2004. Mortality ratios were calculated using standardised mortality ratios (SMRs). Associations between haemoglobin A1c (HbA1c) levels and mortality were studied with a Cox proportional hazard model. HbA1c levels were studied as continuous and as categorical variables.Results A total of 335 patients died after a median follow-up period of 5.8 years. The SMR (95% confidence interval [CI]) for total mortality was 1.86 (95% CI = 1.66 to 2.06) and 2.24(95% CI = 1.91 to 2.61) for cardiovascular mortality. For each 1% increase in HbA1c there was a 21% increase in the hazard ratio for total mortality. When compared with the target HbA1c group (HbA1c 6.5-7%), the group with very poor glycaemic control (HbA1c &gt;9%) had a hazard ratio of 2.21 (95% CI = 1.42 to 3.42) for total mortality. The group with normal glycaemic control (HbA1cConclusion HbA1c level was associated with mortality and this effect seemed largely attributable to patients who were in really poor glycaemic control. The absence of differences in mortality in the groups with lower HbA% levels supports the position that there is no basis for continually decreasing the therapeutic target HbA1c level in patients with type 2 diabetes mellitus.</p

Cruising for Olivia: Lesbian Celebrity and the Cultural Politics of Coming out in Sport

Objective The relationship between low birth weight and elevated blood pressure in adult life is well established but presently unexplained. Both microvascular dysfunction and insulin resistance have been proposed as a possible explanation. We have examined the relation between birth weight and blood pressure in 30 healthy subjects exhibiting a wide range of insulin sensitivity, and assessed whether microvascular function and/or insulin resistance may underlie this relationship. Methods Birth weight data were obtained from birth announcements. Blood pressure was measured with an ambulatory blood pressure monitor and insulin sensitivity was assessed by the hyperinsulinaemic, euglycaemic clamp technique. Microvascular function, i.e. capillary recruitment and endothelium-dependent and -independent vasodilatation in the skin, was evaluated by videomicroscopy and iontophoresis of acetylcholine and sodium nitroprusside. Results Birth weight was significantly associated with blood pressure (r = -0.50; P <0.05), capillary recruitment (r = +0.52; P <0.05), acetylcholine-mediated vasodilatation (r = +0.40; P <0.05), insulin sensitivity (r = +0.62; P <0.01) and waist-to-hip ratio (r = -0.42; P <0.05). Regression analysis showed a significant association of birth weight with 24 h systolic blood pressure (regression coefficient: -7.6 mmHg/kg; 95% confidence interval: -13.0 to -1.0). Adjustment for capillary recruitment and waist-to-hip ratio decreased the regression coefficient by 39 and 41%, respectively. The results were similar after adjustment for age, sex or body mass index. Conclusion These results suggest that capillary recruitment and body fat distribution may partly explain the relationship between birth weight and blood pressure.

Urinary albumin excretion rate during angiotension II infusion in microalbuminuric patients with insulin and non-insulin- dependent diabetes mellitus

As angiotensin-converting enzyme inhibition is accompanied by a marked decrease in glomerular protein loss, the hypothesis was tested that an increase of the glomerular transcapillary hydraulic pressure difference by exogenous angiotensin II would increase microalbuminuria in patients with insulin (IDDM) and non-insulin-dependent diabetes mellitus (NIDDM). Acute effects of increasing doses of angiotensin II (1, 3 and 6 ng/kg/min) were studied on mean arterial pressure (MAP), glomerular filtration rate (GFR), effective renal plasma flow (ERPF), filtration fraction (FF), total renal vascular resistance (TRVR), and urinary albumin excretion rate (UAER) in 11 IDDM and 11 NIDDM microalbuminuric patients. Angiotensin II infusion changed MAP from 100 +/- 3 mmHg at baseline to 105 +/- 3, 111 +/- 3, and 116 +/- 3 mmHg (P < 0.001), ERPF from 542 +/- 29 to 478 +/- 24, 429 +/- 23, and 382 +/- 19 ml/min (P < 0.001), FF from 20.2 +/- 0.06 to 23.1 +/- 0.7, 27.1 +/- 1.1, and 29.8 +/- 1.2% (P < 0.001), and TRVR from 9454 +/- 809 to 11,158 +/- 930, 13,310 +/- 1206, and 15,538 +/- 1362 dyne s cm-5 (P < 0.001). GFR and UAER, however, did not change significantly. Therefore, during angiotensin II infusion ERPF decreased, while FF and TRVR increased. As UAER and GFR remained unchanged, the presumed rise in intraglomerular capillary pressure by exogenous angiotensin II did not increase UAER. We suggest that during manipulation of the renin-angiotensin system, as in other renal diseases with proteinuria, factors other than glomerular transcapillary hydraulic pressure determine the degree of urinary albumin loss in microalbuminuric IDDM and NIDDM patients
