Clinical implementation of value based healthcare: Impact on outcomes for lung cancer patients.

Value based Healthcare (VBHC) focuses on patient centered outcomes, by incorporating Patient Reported Outcome Measures (PROMS). Expectations on the benefits of VBHC are high, but few data are available that validate its routine use. We wanted to investigate if VBHC is feasible and beneficial for lung cancer patients in clinical practice. METHOD: We developed a digital transmural care pathway for lung cancer patients. During systemic therapy, patients digitally reported side effects weekly. Every six weeks, quality of life was reported trough EORTC questionnaires. Case-mix variables, treatment approaches and outcome indicators were systematically collected. We evaluated the compliance of the patients with the digitally reporting system and the impact of the care pathway on patient centered outcomes such as emergency department (ED) visits, time spent on the oncology day clinic, survival and quality of death. RESULTS: 221 lung cancer patients were included in the care pathway. 3091 weekly questionnaires were digitally collected. Compliance with the weekly digital follow-up was 92%: 2835 of 3091 questionnaires were completed. Patients in the care pathway had significantly less ED visits (3.5% vs 4.8%, p 0.04) and a shorter length of stay at the day clinic (2.5 h vs 4.1 h, p < 0,05) compared to routine clinical care. In stage IV lung cancer patients, overall survival was significantly higher in the care pathway (447 days (95% CI 379-663)) compared to routine care (286 days (95% CI 191-400)) (p = 0,025). CONCLUSION: Implementation of value based healthcare is feasible and beneficial in daily clinical care for lung cancer patients.

Clubbing and hypertrophic osteoarthropathy: insights in diagnosis, pathophysiology, and clinical significance.

BACKGROUND: Digital clubbing and hypertrophic osteoarthropathy (HOA) form a diagnostic challenge. Subtle presentations of clubbing are often missed. The underlying pathophysiology remains unclear. Establishing a differential diagnosis based on nonspecific signs can be cumbersome. Finally, the prognostic value of clubbing and HOA remains unclear. OBJECTIVE: This article reviews clinical criteria and pathophysiology of clubbing and HOA. A diagnostic algorithm is proposed, based on etiology and current insights. The prognostic impact on associated diseases is discussed. METHODS: The Internet databases Medline and Embase were searched. Articles were selected based on relevance of abstract, article type and impact of the journal. RESULTS: Diagnostic criteria include Lovibond's profile sign, distal/interphalangeal depth ratio and Schamroth's sign. Three pathophysiological causes of clubbing can be distinguished: hypoxia, chronic inflammation and aberrant vascularization. A prominent role for vascular endothelial growth factor is suggested. Associated symptoms and clinical signs should guide the initial diagnostic evaluation. Finally, clubbing is a negative prognostic factor in certain pulmonary disorders, including cystic fibrosis.
