The iBLAD study: patient-reported outcomes in bladder cancer during oncological treatment: a multicenter national randomized controlled trial.

ABSTRACT:

Background

Patient-reported outcomes (PROs) are getting widely implemented, but little is known of the impact of applying PROs in specific cancer diagnoses. We report the results of a randomized controlled trial (RCT) of the active use of PROs in patients with locally advanced or metastatic bladder cancer (BC) undergoing medical oncological treatment (MOT) with focus on determining the clinical effects of using PROs during chemo- or immunotherapy compared to standard of care.

Methods

We recruited patients from four departments of oncology from 2019 to 2021. Inclusion criteria were locally advanced or metastatic BC, initiating chemo- or immunotherapy. Patients were randomized 1:1 between answering selected PRO-CTCAE questions electronically once weekly with a built-in alert-algorithm instructing patients of how to handle reported symptoms as a supplement to standard of care for handling of side effects (intervention arm (IA)) vs standard procedure for handling of side effects (control arm (CA)). No real-time alerts were sent to the clinic when PROs exceeded threshold values. Clinicians were prompted to view the completed PROs in the IA at each clinical visit. The co-primary clinical endpoints were hospital admissions and treatment completion rate. Secondary endpoints were overall survival (OS), quality of life (EORTC's QLQ-C30 and QLQ-BLM30) and dose reductions.

Results

228 patients with BC were included, 76% were male. 141 (62%) of the patients had metastatic disease. 51% of patients in the IA completed treatment vs. 56% of patients in the CA, OR 0.83 (95% CI 0.47-1.44, p = 0.51). 41% of patients in the IA experienced hospitalization vs. 32% in the CA, OR 1.48 (95% CI 0.83-2.65, p = 0.17). OS was comparable between the two arms (IA: median 22.3mo (95% CI 17.0-NR) vs. CA: median 23.1mo (95% CI 17.7-NR). Patient and clinician compliance was high throughout the study period (80% vs 94%).

Conclusions

This RCT did not show an effect of PRO on completion of treatment, hospitalizations or OS for BC patients during MOT despite a high level of patient and clinician compliance. The lack of real-time response to alerts remains the greatest limitation to this study.

Project description:A previous randomized, controlled trial of tai chi showed improvements in objectively measured balance and other motor-related outcomes in patients with Parkinson's disease. This study evaluated whether patient-reported outcomes could be improved through exercise interventions and whether improvements were associated with clinical outcomes and exercise adherence. In a secondary analysis of the tai chi trial, patient-reported and clinical outcomes and exercise adherence measures were compared between tai chi and resistance training and between tai chi and stretching exercise. Patient-reported outcome measures were perceptions of health-related benefits resulting from participation, assessed by the Parkinson's Disease Questionnaire (PDQ-8) and Vitality Plus Scale (VPS). Clinical outcome measures included motor symptoms, assessed by a modified Unified Parkinson's Disease Rating Scale-Motor Examination (UPDRS-ME) and a 50-foot speed walk. Information on continuing exercise after the structured interventions were terminated was obtained at a 3-month postintervention follow-up. Tai chi participants reported significantly better improvement in the PDQ-8 (-5.77 points, P = 0.014) than did resistance training participants and in PDQ-8 (-9.56 points, P < 0.001) and VPS (2.80 points, P = 0.003) than did stretching participants. For tai chi, patient-reported improvement in the PDQ-8 and VPS was significantly correlated with their clinical outcomes of UPDRS-ME and a 50-foot walk, but these correlations were not statistically different from those shown for resistance training or stretching. However, patient-reported outcomes from tai chi training were associated with greater probability of continued exercise behavior than were either clinical outcomes or patient-reported outcomes from resistance training or stretching. Tai chi improved patient-reported perceptions of health-related benefits, which were found to be associated with a greater probability of exercise adherence. The findings indicate the potential of patient perceptions to drive exercise behavior after structured exercise programs are completed and the value of strengthening such perceptions in any behavioral intervention.

Project description:IntroductionLung cancer is the most common cancer in China, with the highest mortality rate. Surgery is the primary treatment for early lung cancer. However, patients with lung cancer have a heavy burden of symptoms within 3 months after surgery, which seriously affects their quality of life (QOL). The symptom management model based on the patient-reported outcome (PRO) is considered the best caregiving model. The clinical evidence about the symptom management of lung cancer within 3 months after the operation is very limited. Herein, we propose a randomized controlled trial to evaluate the PRO score-based monitoring and alert system for follow-up on psychological and physiological symptoms of lung cancer patients within 3 months after surgery and further investigate the effect of intervention measures based on this PRO score-based system.Methods and analysisThis multicenter, open-label, randomized, parallel superiority trial will be conducted at four hospitals in China. A total of 440 lung cancer patients will be recruited in this study, who will be randomly assigned to the intervention group or the control group in a ratio of 1:1. Any of the target symptoms reaches the preset threshold (score ≥ 4), the patients will accept the symptom management advices based on the PRO. The patients in the control group will follow the current standard procedure of symptom management. The symptom management system is an electronic management system based on WeChat mini programs. All patients will be evaluated for symptoms through the lung cancer module of the MDASI lung cancer-specific scale on the day before surgery, days 1, 3, 5, and 7 after surgery, and once a week during the 12-week post-discharge period. Simultaneously, the EORTC QLQ-C30 scale will be used to evaluate patients' quality of life at baseline and the fourth and twelfth week after the surgery. The mean number of symptom threshold events of the intervention and the control groups were compared by t-test, and the changes of PRO were compared by a mixed effect model. The primary endpoint has been set as the 12-week post-discharge period.DiscussionThis study will test the feasibility of the symptom management system based on the mobile social media applet in postoperative caregiving and the efficacy of psychiatrist-assisted treatment and provide evidence in managing the symptoms of patients in the medium and long term.Trials registrationTrials registration number: ChiCTR 2200058876, Registered 18 April 2022.

Project description:ObjectiveTelephone based health coaching (TBHC) seems to be a promising approach to foster self-management in patients with chronic conditions. The aim of this study was to evaluate the effectiveness of a TBHC on patient-reported outcomes and health behavior for people living with chronic conditions in Germany.MethodsPatients insured at a statutory health insurance were randomized to an intervention group (IG; TBHC) and a control group (CG; usual care), using a stratified random allocation before giving informed consent (Zelen's single-consent design). The TBHC was based on motivational interviewing, goal setting, and shared decision-making and carried out by trained nurses. All outcomes were assessed yearly for three years. We used mixed effects models utilizing all available data in a modified intention-to-treat sample for the main analysis. Participants and study centers were included as random effects. All models were adjusted for age, education and campaign affiliation.ResultsOf the 10,815 invited patients, 4,283 returned their questionnaires at baseline. The mean age was 67.23 years (SD = 9.3); 55.5% were female. According to the model, TBHC was statistically significant superior to CG regarding 6 of 19 outcomes: physical activity in hours per week (p = .030) and in metabolic rate per week (p = .048), BMI (p = .009) (although mainly at baseline), measuring blood pressure (p< .001), patient activation (p< .001), and health literacy (p< .001). Regarding stages of change (p = .005), the IG group also showed statistically different results than the CG group, however the conclusion remains inconclusive. Within-group contrasts indicating changes from baseline to follow-ups and significant between-group comparisons regarding these changes supported the findings. Standardized effect sizes were small. TBHC did not show any effect on mental QoL, health status, alcohol, smoking, adherence, measuring blood sugar, foot monitoring, anxiety, depression and distress. Campaign-specific subgroup effects were detected for 'foot monitoring by a physician' and 'blood sugar measurement'.ConclusionTBHC interventions might have small effects on some patient reported and behavioral outcomes.Practice implicationsFuture research should focus on analyzing which intervention components are effective and who profits most from TBHC interventions.RegistrationGerman Clinical Trials Register (Deutsches Register Klinischer Studien; DRKS): DRKS00000584.
