Abstract

Background

The DoloTest is a newer health-related quality of life (HRQoL) monitoring instrument for pain, not yet validated for headache.

Aims

To examine the usefulness of the DoloTest in a specialized headache center.

Methods

The sample consisted of patients referred to psychologists from the Danish Headache Center (DHC) for whom the test was carried out at start of, end of, and 6 months after treatment. Points on eight scales of the test were measured (values ranged from 0 to 100), then totaled (0 to 800). Scores were analyzed using Wilcoxon Signed Ranks test. The correlation between headache days and DoloTest scores were computed using linear regression adjusted for age. Qualitative feedback on usefulness of the test were gathered from psychologists.

Results

Of 135 patients included, 105 completed treatment. On average, headache days decreased from 22 days per month at start of treatment (SD 9.0, median 29) to 18 days at end of treatment (SD 10.8, median 19) (p<0.001). At end of treatment, DoloTest scores improved for pain (p=0.015) and reduced energy and strength (p=0.034). At 6 months’ follow-up, total scores improved (p=0.034), as well as component scores for pain (p=0.010), problems with strenuous activity (p=0.045) and reduced energy and strength (p=0.012). Correlation between reduced headache days and improved DoloTest scores was 0.303 (p=0.028). Psychologists found the test useful in monitoring and evaluating patients.

Conclusions

The DoloTest was useful for psychoeducation and for monitoring the effect of headache treatment.

Implications

The DoloTest is a potential HRQoL monitoring instrument for headache patients. We recommend further validation studies.

Research funding: No external funding has been given to this project.

Conflict of interest: The authors declare no conflicts of interest of relevance to this project.

Informed consent: Informed consent was obtained from all participants.

Ethical approval: As a service and quality improvement project, the project fell outside the scope of research ethics review in Denmark. The DoloTest was part of the standard evaluation procedure carried out by psychologists at the Danish Headache Center. All central person registry (CPR) numbers were replaced with project identification codes (numbers and letters) to ensure anonymity. Only one psychologist (DKN) had access to all the patients’ CPR numbers. Two authors (MLW and MKN) had access to raw data in anonymized form during statistical analysis.Permission was granted by EvidenceProfile ApS, Denmark to use the DoloTest at the DHC for a trial period. EvidenceProfile ApS, Denmark did not receive any data from the project, and did not have any influence on the decision to publish results of the study. Neither the DHC nor the authors received monetary compensation from EvidenceProfile ApS, Denmark.
