The two datasets were analysed separately. On these two items, low scores represent good perceived blood glucose control. One of the best examples showing the efficacy of DTSQ is the assessment of insulin analogs. In the very few three instances where the ranked results differ noticeably from the raw results, these are indicated on the table.
Published online Oct Patient perceptions of diabetes and diabetes therapy: Assessing quality of life. Type 2 trial Unlike the type 1 study, no treattment effect of Treatment was seen for patients with type 2 diabetes.
Psychometric analysis was carried out to check the validity and reliability of the English- and German-speaking versions separately for language, pooled for type of diabetesusing factor analysis with principal components as the extraction method with Varimax rotation. Aseltine and colleagues suggested that status measures may not be an error-free method of measuring change, because patients’ standards, or the criteria they use to determine their ratings, may change following treatment as their frame of reference may change, so that apparently identical ratings are not, in fact, comparable.
The improvement in treatment satisfaction may also reduce the risk of dropout from treatment. When the associations between the DTSQ score and other clinical parameters were examined, there was a weak negative correlation between the total score of DTSQ and the intensity of treatment i. Rapid-acting insulin analogs have been shown to improve postprandial glycemic excursion and reduce hypoglycemia compared with regular insulin due to their rapid onset of action [ 12 ].
Translation and clinical evaluation. Using non-parametric tests on the same Type 1 treatment satisfaction data, a similarly high and significant final z value of 3.
This would also enable them to draw comparisons between their findings and those from earlier studies using only the DTSQs.
Received Jul 15; Accepted Oct There was also a significant positive correlation between Q 2 and 3. This was modified and adopted from satifsaction [ 20 ]. It also remains unclear whether an improvement in the DTSQ score translates into an improvement in other clinical outcomes, including cardiovascular outcomes and overall mortality.
DTSQs and DTSQc – Diabetes Treatment Satisfaction Questionnaire, status and change versions
Patients are inclined to make the best of their current treatment and only become aware of its drawbacks when they can compare it with something better [ 1 ]. Therefore, improvement in treatment satisfaction may foster the achievement of long-term glycemic stability, eventually reducing the risk of developing diabetic complications Figure 1.
At endpoint patients completed the Status measure before completing the Change version. These studies suggest that the DTSQc djabetes not simply elicit positive change responses regardless of treatment circumstances, but does genuinely reflect a response to improvements in treatment borne out by experience. Data analysis Prior to performing psychometric analyses, the combinability of the subgroups defined by country and type of diabetes was tested by a method described elsewhere [ 18 ], which confirmed the acceptability of combining the samples.
Using a status measure, patients’ satisfaction with a new treatment may appear to be no different from their satisfaction with their old treatment when they already felt satisfied with the previous treatment, and differences between treatments may be underestimated.
A frequently observed feature in trials of new treatments for diabetes is therefore a relatively high level of patient satisfaction with pre-trial treatment [ 2 – 5 ]. However, as the effect sizes based on these ts dlabetes significantly despite the positive correlations, the stated results are satusfaction. However, the relationship between a patient and doctors medical staffrather than medications or treatment strategies, may have duabetes major impact on treatment satisfaction.
Table 8 “Perceived Hypoglycaemia” — Descriptive Statistics. In the case of the two perceived blood glucose control items, the DTSQc is unequivocally more responsive diabetez improvements in hypoglycaemia for satisfaaction in the At Floor group.
Diabetes Treatment Satisfaction Questionnaire, status and change versions (DTSQs and DTSQc)
Psychological outcomes after initiation of insulin treatment in patients with type II diabetes [Abstract] Diabetologia. Treatment Satisfaction scores across both questionnaires were ranked separately for each study. Table 1 Major questionnaires for PROs used internationally in patients with diabetes. The new Change measure allowed patients equal opportunity for indicating improvement and deterioration. Glucagon-like peptide 1 Quesfionnaire analogue combined with insulin reduces HbA1c and weight with low risk of hypoglycemia and high ssatisfaction satisfaction.
Novel therapeutic options, such as insulin analogs, incretin-based therapy and sodium-glucose cotransporter 2 SGLT2 inhibitors, have been shown to improve patient satisfaction using DTSQ for assessments. Conclusion Although the DTSQc measure was introduced to combat problems resulting from ceiling effects, it was found here that the measure of treatment satisfaction derived from the DTSQc questionnaire was more responsive than that derived from the DTSQsDiff measure, even when scores were not at ceiling, and so can be recommended as the method of choice for measuring change in satisfaction alongside the DTSQs.
Ceiling effect reduces the validity of the Diabetes Treatment Satisfaction Questionnaire. It is composed of eight questions, each of which is scored by patients on a scale ranging from zero e. Standards of Medical Care in Diabetes— This suggests a negative association between treatment burden and treatment satisfaction, although a previous study reported an improvement in the DTSQ score after implementation of insulin therapy in poorly-controlled patients with T2DM [ 22 ].
The questionnaire is composed of two different factors. The goal of diabetes treatment is the prevention of the onset and progression of micro- and macrovascular complications as well as the achievement of quality of life QOL and longevity equivalent to people without diabetes. The one study of insulin lispro that used the DTSQ Change measure was able to show the substantial increases in patient satisfaction [ 17 ] apparent to clinicians in their routine practice, instead of the more modest, though significant, improvements apparent with the DTSQ Status [ 17 ].
Africa for the first time and the German is used here for the first time in Germany and Switzerland as well as Austria. Of note, we found that the satisfaction with their attending doctor showed the strongest association with the total DTSQ score among the clinical parameters. Each of these t-tests is for independent groups. The improvement in patient satisfaction has been also shown in the patients treated with incretin-related agents queshionnaire 81516 ], sodium-glucose cotransporter 2 SGLT2 inhibitors [ 17 ], fixed-dose combination tablets [ 18 ] and weekly dipeptidyl peptidase-4 DPP-4 inhibitors [ 19 ].
With the exception of Q 2 and 3, the six questions related to the first dtss were significantly correlated with each other as well as with the total score Table 2 [ 20 ]. Furthermore, as co-morbidities rreatment affect the results of DTSQ, the use of more than two different measures should be considered to comprehensively evaluate PROs.
In the type 1 study, in addition to insulin glargine or NPH, regular human insulin was administered before each meal.
