American Diabetes Association Glycemic Targets: At endpoint patients completed the Status measure before completing the Change version. National Center for Biotechnology InformationU. Greatment R, Hopkins A, editor. A principal inclusion criterion was level of glycosylated haemoglobin GHb at Visit 1: Queztionnaire, as co-morbidities may affect the results of DTSQ, the use of more than two different measures should be considered to comprehensively evaluate PROs.

Abstract The efficacy of diabetes treatment should not be evaluated solely by HbA1c levels as they should also focus on patient-reported outcomes PROssuch as patient satisfaction, diaabetes and quality of teeatment. Change in treatment satisfaction Type 1 trial Treatment Satisfaction increased overall in both the insulin glargine and NPH treatment groups, but with a significantly greater increase in the insulin glargine group. These results suggest that the patients who experience a greater burden of hyperglycemia also tend to experience a greater burden of hypoglycemia, while the satisfacfion of hypoglycemia is more strongly correlated with reduced treatment satisfaction compared to the burden of hyperglycemia.

These results emphasize the importance of patient satisfaction in the assessment of diabetes treatment, which cannot be fully assessed by glycemic indices, including HbA1c.

Howorka and colleagues [ 17 ] have already found the German DTSQc to perform well with Austrian patients with type 1 diabetes comparing meal-related insulins. All communality estimates exceeded the criterion of 0. The first factor consisted of the six treatment satisfaction items, and the second factor consisted of the two subjective metabolic control items.

In conclusion, the study demonstrated that the underlying dimensions of the DTSQ for both groups were treatment satisfaction and hyper- and hypoglycemia, all measures had excellent reliability 5 , and well-being is an important predictor of treatment satisfaction for both groups of patients. These findings were consistent with those reported in the U.

The first factor assesses treatment satisfaction and consists of six questions Q 1, 4, 5, 6, 7 and 8. These six questions showed good internal consistency, with a Cronbach alpha score of 0. Treatment satisfaction is assessed as the sum of the scores of the six questions on the first factor total score 36 , with a higher score indicating higher treatment satisfaction.

The other reasons for this wide usage of DTSQ include the following: 1 it is able to assess treatment satisfaction irrespective of the treatment methods used, including dietary therapy, therapy with oral hypoglycemic agents OHAs or insulin therapy; 2 it is relatively easy to answer and places a smaller burden on patients, since the questions are simple and there are only eight items, which is fewer compared to other questionnaires; and 3 the results can be directly compared to those obtained in other countries internationally.

One of the best examples showing the efficacy of DTSQ is the assessment of insulin analogs. 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 ].

They also allow patients to inject at mealtimes, which promotes convenience when compared with regular insulin, which requires injection 30 mins before a meal. However, studies have shown the same efficacy of rapid-acting insulin analogs compared with regular insulin in terms of HbA1c levels. These results emphasize the importance of patient satisfaction in the assessment of diabetes treatment, which cannot be fully assessed by glycemic indices, including HbA1c.

To date, the assessment of PROs, including DTSQ, is essential for evaluating the efficacy of novel anti-diabetic agents and assessing the glucose-lowering effect related to HbA1c levels. The improvement in patient satisfaction has been also shown in the patients treated with incretin-related agents [ 8 , 15 , 16 ], sodium-glucose cotransporter 2 SGLT2 inhibitors [ 17 ], fixed-dose combination tablets [ 18 ] and weekly dipeptidyl peptidase-4 DPP-4 inhibitors [ 19 ].

The results have been reported previously. However, although the original articles were written in Japanese, we would like to describe the study briefly [ 20 , 21 ]. Questionnaires regarding the clinical parameters were also conducted simultaneously and the relationships of these clinical parameters with DTSQ scores were assessed.

The questionnaires were filled out anonymously and the patients answered the questionnaires in the waiting room outside the examination room. With the exception of Q 2 and 3, the six questions related to the first factor were significantly correlated with each other as well as with the total score Table 2 [ 20 ]. There was also a significant positive correlation between Q 2 and 3.

Q 2 was negatively correlated with Q 1, while Q 3 was negatively correlated with Q 4, 5, 8 and the total score. These results suggest that the patients who experience a greater burden of hyperglycemia also tend to experience a greater burden of hypoglycemia, while the burden of hypoglycemia is more strongly correlated with reduced treatment satisfaction compared to the burden of hyperglycemia.

This was modified and adopted from reference [ 20 ]. Total score was calculated as the sum of scores of Q 1, 4, 5, 6, 7 and 8. 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. 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 ].

There was no apparent correlation between total DTSQ score and age or sex in our cohort. Correlations between total DTSQ score and clinical parameters. No or only modest associations between HbA1c levels and DTSQ score have also been reported [ 11 , 13 , 14 ], which is consistent with our results.

This indicates that treatment satisfaction is not necessarily related to glycemic control. This suggests that patients with higher treatment satisfaction also experience higher self-efficacy, resulting in better adherence to therapy. These results indicate that the assessment of treatment satisfaction with DTSQ may predict dropout from therapy. On the contrary, an improvement in treatment satisfaction, which can be assessed with DTSQ, may reduce the risk of dropout.

The results have been reported previously. Translation and clinical evaluation. Diabetes Treatment Satisfaction Questionnaire: In the case of the two perceived blood glucose control items, the DTSQc is unequivocally more responsive to improvements in hypoglycaemia for those in the At Floor group. This article has been cited by other articles in PMC. In this review, we summarize the current topics in DTSQ, introducing our own experience, and discuss the role of PROs in diabetes treatment.

Furthermore, as co-morbidities may affect the results of DTSQ, the use of more than two different measures should be considered to comprehensively evaluate PROs. Howorka et al [ 17 ] found in a crossover study that patients who went back in the second phase from lispro to standard soluble insulin showed a decline in satisfaction on the retrospective measure, indicating that the DTSQc does not always invoke positive responding.

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 ]. DTSQ is now translated into more than languages, including Japanese [ 11 ], and is one of the most widely used questionnaires in the field of diabetes. There was also a significant positive correlation between Q 2 and 3.

Skewed satisfaction scores reflect a real phenomenon and not a failure of the scale, so changing the scale is not a good solution. Since the DTSQc is a measure of comparative satisfaction, a measure of absolute Satisfaction should always be used at baseline using the original Status version of the DTSQ, to enable researchers to put the findings of the Change measure into context, i.

JV carried out analyses of the effect sizes, and contributed to the interpretation and to manuscript preparation. These results emphasize the importance of patient satisfaction in the assessment of diabetes treatment, which cannot be fully assessed by glycemic indices, including HbA1c.

This suggests that patients with higher treatment satisfaction also experience higher self-efficacy, resulting in better adherence to therapy. Another potential concern with a retrospective measure of change is that it might reflect a socially desirable tendency to report improved satisfaction whatever the treatment rather than genuine change.
