Identification of latent classes in patients who are receiving biotherapy based on symptom experience and its effect on functional status and quality of life.

PURPOSE/OBJECTIVES: to identify subgroups of patients receiving biotherapy with pain, fatigue, sleep disturbance, and depression and to determine functional status and quality of life differences between subgroups. DESIGN: a descriptive, prospective, cohort study design. SETTING: internet-based survey. SAMPLE: 187 patients with cancer receiving biotherapy. METHODS: pain intensity, Piper Fatigue Scale, General Sleep Disturbance Scale, Center for Epidemiological Studies-Depression, Karnofsky Performance Scale, and the Multidimensional Quality of Life Scale-Cancer were used at two time points one month apart (T1 and T2). Latent profile analysis identified subgroups. MAIN RESEARCH VARIABLES: biotherapy, symptoms, functional status, and quality of life. FINDINGS: At T1 (N = 187), five patient subgroups were identified, ranging from subgroup 1 (mild fatigue and sleep disturbance) to subgroup 5 (severe on all four symptoms). At T2 (N = 114), three patient subgroups were identified, ranging from subgroup 1 (mild pain, fatigue, and sleep disturbance without depression) to subgroup 3 (mild pain, moderate fatigue, and sleep disturbance with severe depression). At each time point, the patient subgroup with the most severe symptoms showed significantly lower functional status and quality of life. CONCLUSIONS: as with other cancer treatments, biotherapy can be divided into similar patient subgroups with four prevalent symptoms. Subgroups of patients differ in functional status and quality of life as a result of symptom severity. IMPLICATIONS FOR NURSING: clinicians should assess and identify patients with severe levels of the four prevalent symptoms and offer appropriate interventions. Future study is needed to investigate the factors that contribute to symptom severity and to examine the occurrence of symptom clusters that may place patients at increased risk for poorer outcomes.

Mucositis pain induced by radiation therapy: prevalence, severity, and use of self-care behaviors.

Pain from radiation therapy (RT)-induced mucositis is a significant clinical problem for patients with head and neck cancer (HNC). The purpose of this study was to determine the pattern, severity, and time course of RT-induced mucositis pain; self-care behaviors (SCBs) used to manage mucositis pain; and the effectiveness of these behaviors in relieving such pain. Forty-nine patients with HNC were assessed using the MacDibbs Mouth Assessment Tool to determine the severity of RT-induced mucositis pain over their course of RT and at a one-month follow-up visit. All patients developed pain due to RT-induced mucositis. A Self-Care Diary was used weekly by patients to record SCBs and their effectiveness. The most effective SCBs for RT-induced mucositis pain were mouth rinsing and using oral analgesics. However, more severe pain with swallowing was not managed well throughout the study. Future studies need to test more effective strategies to manage RT-induced mucositis pain.
