How much psychological distress is experienced at home by patients with palliative care needs in Germany? A cross-sectional study using the Distress Thermometer.

OBJECTIVE: The aims of the present study were (1) to describe the prevalence of psychosocial distress in palliative care patients living at home and the related factors, and (2) to test implementation of the Distress Thermometer (DT) within a home-based palliative care service. METHOD: Ours was a 15-month prospective study beginning in September of 2013 in western Germany with consecutive patients cared for by a home care palliative care service. The research was implemented during the first visit by the home care team. Patients were excluded if they were under 18 years of age, mentally or physically unable to complete the assessment questionnaires as judged by their healthcare worker, or unable to understand the German language. During the first encounter, the Distress Thermometer (DT), a Problem List (PL), and a structured questionnaire for evaluation were applied and sociodemographic and medical data collected. RESULTS: A total of 103 patients (response rate = 70%; mean age = 67; female = 54%; married = 67%; oncological condition = 91%; Karnofsky Performance Status [KPS] score 0-40 = 34%, 50-70 = 60%, >80 = 6%) were included. The incidence of distress (DT score ≥4) was 89.3% (mean = 6.3 ± 2.5). No statistical association was found between level of distress and sociodemographic or medical factors. The five most reported problems were "fatigue" (90%), "getting around" (84%), "eating" (63%), "bathing/dressing" (60%), and "sleep" (57%). The number of problems reported correlated with level of distress (ρ = 0.34). The DT was comprehensible, and 80% considered its completion as unremarkable, while 14% found it "relieving." SIGNIFICANCE OF RESULTS: A significant proportion of patients treated at home reported symptoms of distress. The most oft-mentioned problems were physical and emotional in nature. The findings of our study highlight the importance of creating new concepts and structures in order to address the psychosocial needs of patients in home care with palliative needs.

Accuracy of the Distress Thermometer for home care patients with palliative care needs in Germany.

OBJECTIVE: Our aim was to examine the accuracy of the German version of the Distress Thermometer (DT) compared with the Hospital Anxiety and Depression Scale (HADS) in patients with palliative care needs living at home. METHOD: Ours was a 15-month cross-sectional study beginning in September of 2013 in Germany with consecutive patients cared for by a palliative home care service. The survey was implemented during the initial visit by a home care team. Patients were excluded if they were under 18 years of age, mentally or physically unable to complete the assessment questionnaires as judged by their healthcare worker, or unable to understand the German language. During the first encounter, the DT and HADS were applied, and sociodemographic and medical data were collected. RESULTS: A total of 89 persons completed both the HADS and DT questionnaires (response rate = 59.7%; mean age = 67 years; female = 55.1%; married = 65.2%; living home with relatives = 73.0%; oncological condition = 92.1%; Karnofsky Performance Scale [KPS] score: 0-40 = 30.3%, 50-70 = 57.3%, >80 = 6.7%). The mean DT score was 6.3 (±2.3), with 84.3% of participants scoring above the DT cutoff (≥4). The mean HADStotal score was 17.9 (±7.8), where 64% of participants had a total HADS score (HADStotal) ≥15, 51.7% reported anxiety (HADSanxiety ≥ 8), and 73% reported depression (HADSdepression ≥ 8). Using the HADS as a gold standard, a DT cutoff score ≥5 was optimal for identifying severe distress in patients with palliative care needs, with a sensitivity of 93.0%, a specificity of 34.4%, a positive predictive value (PPV) of 73.3%, and likelihood ratios LR+ = 1.42 (<3) and -LR = 0.203 (<0.3). SIGNIFICANCE OF RESULTS: The DT performed satisfactorily compared to the HADS in screening for distress in our study and can be employed as an instrument for identification of patients with distress. Consequent to the high prevalence of distress, we recommend its routine use for screening distressed persons at home with palliative care needs in order to offer adequate support.
