Law, public health, and the diabetes epidemic

Benefits and risks of standardization, harmonization and conformity to opinion in clinical laboratories

Large laboratory systems that include facilities with a range of capabilities and capacity are being created within consolidated healthcare systems. This paradigm shift is being driven by administrators and payers seeking to achieve resource efficiencies and to conform practice to the requirements of computerization as well as the adoption of electronic medical records. Although standardization and harmonization of practice improves patient care outcomes and operational efficiencies, administratively driven practice conformity (conformity to opinion) also has serious drawbacks and may lead to significant system failure. Juxtaposition of the distinct philosophical approaches of physicians and scientists (i.e. "professionalism") versus administrators and managers (i.e. "managerialism") towards bringing about conformity of the laboratory system inherently creates conflict. Despite an administrative edict to "perform all tests using the same methods" regardless of available "best practice" evidence to do so, medical/scientific input on these decisions is critical to ensure quality and safety of patient care. Innovation within the laboratory system, including the adoption of advanced technologies, practices, and personalized medicine initiatives, will be enabled by balancing the relentless drive by non-medical administration to meet "business" requirements, the medical responsibility to provide the best care possible, and customizing practice to meet individual patient care needs.

Motivational interviewing to explore culturally and linguistically diverse people's comorbidity medication self-efficacy

AIMS AND OBJECTIVES

To examine the perceptions of a group of culturally and linguistically diverse participants with the comorbidities of diabetes, chronic kidney disease and cardiovascular disease to determine factors that influence their medication self-efficacy through the use of motivational interviewing.

BACKGROUND

These comorbidities are a global public health problem and their self-management is more difficult for culturally and linguistically diverse populations living in English-speaking communities. Few interventions have been tested in culturally and linguistically diverse people to improve their medication self-efficacy.

DESIGN

A series of motivational interviewing telephone calls were conducted in the intervention arm of a randomised controlled trial using interpreter services.

METHODS

Patients with these comorbidities aged ≥18 years of age whose preference it was to speak Greek, Italian or Vietnamese were recruited from nephrology outpatient clinics of two Australian metropolitan hospitals in 2009.

RESULTS

The average age of the 26 participants was 73·5 years. The fortnightly calls averaged 9·5 minutes. Thematic analysis revealed three core themes which were attitudes towards medication, having to take medication and impediments to chronic illness medication self-efficacy. A lack of knowledge about medications impeded confidence necessary for optimal disease self-management. Participants had limited access to resources to help them understand their medications.

CONCLUSION

This work has highlighted communication gaps and barriers affecting medication self-efficacy in this group. Culturally sensitive interventions are required to ensure people of culturally and linguistically diverse backgrounds have the appropriate skills to self-manage their complex medical conditions.

RELEVANCE TO CLINICAL PRACTICE

Helping people to take their medications as prescribed is a key role for nurses to serve and protect the well-being of our increasingly multicultural communities. The use of interpreters in motivational interviewing requires careful planning and adequate resources for optimal outcomes.

Associations between depression and diabetes in the community: do symptom dimensions matter? Results from the Gutenberg Health Study

Objectives

While a bidirectional relationship between diabetes and depression has been established, there is little knowledge if the associations are due to somatic-affective or cognitive-affective dimensions of depression.

Research Design and Methods

In a population-based, representative survey of 15.010 participants we therefore studied the associations of the two dimensions of depression with diabetes and health care utilization among depressed and diabetic participants. Depression was assessed by the Patient Health Questionnaire PHQ-9.

Results

We found a linear and consistent association between the intensity of depression and the presence of diabetes increasing from 6.9% in no or minimal depression to 7.6% in mild, 9% in moderate and 10.5% in severe depression. There was a strong positive association between somatic-affective symptoms but not with cognitive-affective symptoms and diabetes. Depression and diabetes were both independently related to somatic health care utilisation.

Conclusions

Diabetes and depression are associated, and the association is primarily driven by the somatic-affective component of depression. The main limitation of our study pertains to the cross-sectional data acquisition. Further longitudinal work on the relationship of obesity and diabetes should differentiate the somatic and the cognitive symptoms of depression.

Diabetes as a risk factor for poorer early postoperative outcomes after shoulder arthroplasty

BACKGROUND

Although diabetes has been associated with increased perioperative morbidity and mortality after hip and knee arthroplasty, its impact on early postoperative outcomes after shoulder replacement remains relatively unexplored. The purpose of the study was to determine the association of diabetes with in-hospital death, complications, length of stay, non-homebound disposition, and cost in patients undergoing shoulder arthroplasty.

METHODS

By use of the Nationwide Inpatient Sample database for the year 2011, an estimated 66,485 patients having undergone shoulder arthroplasty were identified and separated into groups with (21%) and without (79%) diabetes mellitus. Comparisons of specific outcome measures between diabetic and nondiabetic cohorts were performed by bivariate and multivariable analyses with logistic regression modeling.

RESULTS

Diabetes mellitus was independently associated with in-hospital death, a number of perioperative complications, prolonged hospital stay, and increased non-homebound disposition after shoulder arthroplasty. The presence of diabetes was not associated with increased hospital cost.

CONCLUSION

Patients with preexisting diabetes are at higher risk for perioperative morbidity and mortality after shoulder arthroplasty. Future prospective research should explore in more detail the relationship between diabetes and shoulder arthroplasty outcomes.
