Clinical characteristics of depressed patients with comorbid diabetes mellitus

Kellner's Symptom Questionnaire, a Highly Sensitive Patient-Reported Outcome Measure: Systematic Review of Clinimetric Properties

INTRODUCTION

Patient-reported outcomes (PROs) are of increasing importance in clinical medicine. However, their evaluation by classic psychometric methods carries considerable limitations. The clinimetric approach provides a viable framework for their assessment.

OBJECTIVE

The aim of this paper was to provide a systematic review of clinimetric properties of the Symptom Questionnaire (SQ), a simple, self-rated instrument for the assessment of psychological symptoms (depression, anxiety, hostility, and somatization) and well-being (contentment, relaxation, friendliness, and physical well-being).

METHODS

The PRISMA guidelines were used. Electronic databases were searched from inception up to March 2019. Only original research articles, published in English, reporting data about the clinimetric properties of the SQ, were included.

RESULTS

A total of 284 studies was selected. The SQ has been used in populations of adults, adolescents, and older individuals. The scale significantly discriminated between subgroups of subjects in both clinical and nonclinical settings, and differentiated medical and psychiatric patients from healthy controls. In longitudinal studies and in controlled pharmacological and psychotherapy trials, it was highly sensitive to symptoms and well-being changes and discriminated between the effects of psychotropic drugs and placebo.

CONCLUSIONS

The SQ is a highly sensitive clinimetric index. It may yield clinical information that similar scales would fail to provide and has a unique position among the PROs that are available. Its use in clinical trials is strongly recommended.

A comparison of baseline sociodemographic and clinical characteristics between major depressive disorder patients with and without diabetes: a STAR*D report

BACKGROUND

Patients with major depressive disorder (MDD) have high rates of medical comorbidities which can impair MDD treatment. Yet little is known regarding associations between the presence of a serious comorbidity and MDD treatment. The purpose of this study was to examine the baseline sociodemographic and clinical characteristics of MDD outpatients with and without diabetes mellitus to evaluate possible associations between these characteristics and the presence of comorbid diabetes.

METHODS

We gathered baseline sociodemographic and clinical data for 4041 participants with non-psychotic MDD who enrolled in the STAR*D, a large-scale depression treatment protocol, and made comparisons between participants with and without diabetes.

RESULTS

Participants with diabetes were more likely to be male, older, black, Hispanic, unemployed, and have less education, a lower income, higher mental functioning, lower physical functioning, atypical features, increased appetite, psychomotor slowing and leaden paralysis, and were less likely to have concurrent alcohol abuse/dependence, mood reactivity or problems with concentration. We found no significant differences between groups regarding depression severity.

LIMITATIONS

The primary limitation is the lack of a clinical diagnosis of diabetes.

CONCLUSIONS

We found no difference in depression severity between participants with and without diabetes. Diabetes was associated with physical symptoms of depression. Thus treatments for these participants should be directed toward these symptoms.

The association between antidepressant use and hypoglycaemia in diabetic patients: a nested case-control study

PURPOSE

Hypoglycaemia is a limiting factor for glycaemic management of diabetes with intensive insulin and/or oral antidiabetic drug (OAD) regimen. Case reports suggest that antidepressants may interfere with blood glucose metabolism in patients with diabetes mellitus potentially increasing the risk of clinically relevant hypoglycaemia. Comorbid depression treated with antidepressants could therefore further complicate glycaemic control. We have carried out a nested case-control study among diabetic patients to assess the risk of hypoglycaemia requiring hospitalisation associated with the use of antidepressants.

METHODS

Diabetic patients treated with insulin and/or OADs were selected from the Dutch Pharmo system. Exposure to antidepressants was the primary determinant investigated. Use of antidepressants was further subclassified based on the receptor binding profile to investigate whether specific pharmacological properties could explain a potential influence on glucose homeostasis. Conditional logistic regression was used to estimate odds ratios and to adjust for confounding factors.

RESULTS

From the base cohort (40 600 patients), 549 (1.35%) cases were identified and 1897 controls were selected. Current use of any antidepressant was not associated with a significantly higher risk of hypoglycaemia requiring hospitalisation (OR: 1.36 (95%CI: 0.84-2.20)). A trend for a higher risk on hypoglycaemia was identified for antidepressants with high affinity for the serotonin reuptake transporter. The risk on severe hypoglycaemia was increased after 3 years of use (OR: 2.75 (95%CI: 1.31-5.77)).

CONCLUSIONS

It is important for diabetic patients using antidepressants for more than 3 years to pay attention for symptoms of hypoglycaemia and strict blood glucose self-monitoring.

Perspectives of patients with type 2 diabetes following a critical cardiac event - an interpretative approach

AIM

This study aimed to gain in-depth understanding of the actual hospital and home experience of patients with diabetes and a critical cardiac event to assist in developing a pertinent diabetes self-management programme.

BACKGROUND

Type 2 diabetes can lead to cardiac complications requiring critical nursing care. Patients with diabetes and a history of cardiac disease are at greater risk of a further cardiac event. Greater self-efficacy or confidence in regulating diabetes and reducing the risk of a further cardiac event can be achieved through self-management programmes. However, the start of such a programme within the critical care environment presents challenges to critical care staff. It is important to understand patients' experiences and needs to improve quality of care.

DESIGN

An interpretive approach comprising open-ended interviews was used to collect data from patients with type 2 diabetes experiencing a cardiac event who had a coronary care unit admission in 2002-2003.

FINDINGS

The findings revealed that patients with diabetes who had a critical cardiac event experienced considerable feelings of hopelessness and fatigue. Patients also had concerns in the areas of self-confidence and confidence in health professionals. Patients indicated that greater self-confidence and confidence in health professionals would help their ability to manage their daily lives.

CONCLUSION

This paper provides in-depth understanding of the perspectives of patients with type 2 diabetes who have also been hospitalized for a critical cardiac event. This study concluded that further research is needed to fully explore whether enhancing self-confidence for these patients will lead to improved diabetes management, reduced negative feelings and more positive health outcomes.

RELEVANCE TO CLINICAL PRACTICE

The themes identified in this study provide direction and strategies for nursing staff to improve patients' confidence levels and reduce their feelings of hopelessness and fatigue.
