How Do Quality of Life (QoL) and Symptom Burden Evolve in Inpatient Palliative Care (PC) Patients following One Week of Care in a Specialized Palliative Care Unit (PCU)? A Comparison of Two Groups, with One Receiving Specialized Outpatient Palliative Care Prior to Admission

Abstract

Purpose: This study sought to investigate changes in quality of life (QoL) and symptom burden among palliative care patients undergoing one week of inpatient care in a specialized palliative care unit (PCU). The patient population was stratified into two groups, with one group pretreated from pre-admission palliative care (PC) provided by an outpatient multidisciplinary PC team, while the other group did not receive such support prior to admission. Although the average duration of treatment at a PCU in Germany is 1–2 weeks, the question also arises as to whether a significant improvement in symptom burden and QoL can be expected after just one week of PC in a PCU. Methods: PC patients with various cancer entities were prospectively included in a non-randomized study. Patients in group 1 received outpatient specialized PC prior to admission, while patients in group 2 did not. Over an 8-month period, we gathered data from one academic cancer center, utilizing the EORTC QLQ-C30, one of the most widely used patient-reported outcome (PRO) instruments to assess health-related QoL in cancer patients. Patients completed the QLQ-C30 at T0 (admission or one day later) and T1 (one week later), enabling the assessment of potential changes in their QoL and symptom burden over time. Results: A total of 103 patients (51.5% male) were enrolled (group 1: 42%, group 2: 58%). At T0, there were no significant differences regarding QLQ-C30 scores between groups 1 and 2, except from global health/QoL (group 1 mean 20.7, group 2 mean 25.6, p = 0.026). Over the course of one week several significant and clinically relevant changes were found: Emotional functioning demonstrated an uplift in both groups (group 1: mean 41.5 IQR 33 vs. 53.1 IQR 50, p = 0.014, group 2: mean 48.2 IQR 46 vs. 56.8 IQR 58, p = 0.029), as did the global health status (group 1: M 20.7 IQR 17 vs. 36.2 IQR 33, p < 0.001, group 2: M 25.6 IQR 25 vs. 35.3 IQR 33, p < 0.001). Nausea and vomiting showed a reduction (group 1: M 29.9 IQR 17 vs. 6.8 IQR 0, p < 0.001, group 2: M 22.6 IQR 17 vs. 8.2 IQR 0, p < 0.001), along with a notable decline in pain (group 1: M 67.4 IQR 67 vs. 25.3 IQR 17, p < 0.001, group 2: M 73.1 IQR 83 vs. 29.7 IQR 17, p < 0.001). A decrease was observed in insomnia (group 1: M 63.6 IQR 67 vs. 27.6 IQR 33, p < 0.001, group 2: M 60.1 IQR 67 vs. 27.6 IQR 33, p < 0.001). There were no significant differences between groups 1 and 2 in the extent of improvement in the various symptom scales from T0 to T1. Conclusion: The findings of our study demonstrate that QoL and several symptoms prevalent in cancer patients cared for in the PCU experienced significant enhancement over the span of just one week. Both groups, patients receiving specialized outpatient PC prior to admission and those without, equally benefited from inpatient PC. All mentioned changes from T0 to T1 are considered not only significant but clinically relevant.
