Aims: The DIALOG scale has been implemented as a routine patient outcome and experience measure (PROM/PREM) in a mental health trust in East London since 2017. The resulting healthcare dataset was used to estimate satisfaction with life and treatment aspects over time and factors associated with it.
Methods: Variables available from the Trust were DIALOG items, service level, clinical and basic demographic data. Data was extracted in February 2019. Data is described using a range of descriptive statistics and looking at the subgroups: treatment stage, diagnosis, service type. Predictors for average DIALOG scores across patients was explored with clustered linear regression models. A fixed effect model was chosen to estimate the impact of clinical and service related variables on patient's average DIALOG scores over time. Sensitivity analyses with the whole data set and complete cases were carried out.
Results: Of the original 18,481 DIALOG records 12, 592 were kept after data cleaning (5646 patients). The average DIALOG score was 4.8 (SD 1.0) on the 7-point scale. Average satisfaction with life aspects (PROM) was 4.65 (SD 1.1) and with treatment aspects (PREM) was 5.25 (SD 1.17). Across all 11 items, "job situation" scored lowest (mean 4.05) and "meetings with professionals" highest (mean 5.5). Satisfaction for all items increased over time (average increase 0.47). The largest increase was in "mental health" (0.94) and the smallest in "family relationships" (0.34).
Conclusions: Patients in mental healthcare services were "fairly satisfied" in both life and treatment aspects with improvements seen over time. These results will act as a benchmark for clinical services currently implementing DIALOG across the UK and inform local service developments.
