O07.02 - The preferred and actual levels of involvement in decision-making among patients considering adjuvant chemotherapy (ACT) for non-small-cell lung cancer (NSCLC). (ID 2038)
10:30 - 12:00 | Author(s): M. Stockler
Patients with cancer have varying preferences for involvement in decision-making between active, collaborative and passive roles. Previous studies suggest that many patients prefer a more active role than they experienced, and a more active role over time[MSA(1] . We sought the preferred and actual level of involvement in decision-making among patients considering ACT after resection of early NSCLC.
98 patients completed a self-administered questionnaire at baseline (before ACT, if they were having it) and at 6 months (after ACT, if they had it). Preferred and actual level of involvement in decision-making were assessed by the Control Preferences Scale (CPS) and trichotomised into active, collaborative, and passive roles. Health-related quality of life (HRQL) data were assessed by the Patient DATA Form. Differences on the original CPS scale between preferred and actual roles and between preferred roles over time were assessed with the Wilcoxon signed-rank test. Determinants of preference for an active role were assessed with chi-square tests of association in 2x2 tables, summarising by odds ratios (ORs). Wilcoxon rank-sum (WRS) tests were used to assess differences in survival benefits required to make ACT worthwhile between patients preferring active and less active roles.
Most patients were male (55%) with a median age of 64 years (range, 43-79 years), married (74%) and previous smokers (82%). The majority had had a lobectomy (85%), adenocarcinoma histology (63%), and half (46%) had stage II disease. 83 patients decided to have ACT (85%), 15 declined ACT (15%). ACT was most commonly 4 cycles (71%) of cisplatin/ vinorelbine (73%). Preferred role in decision-making at baseline (n=98) was active in 26 (27%), collaborative in 46 (47%), and passive in 26 (27%); and at 6 months (n=73) was active in 15 (21%), collaborative in 37 (51%) and passive in 21 (29%). Preferred decision-making roles were stable over time (p=0.5). Actual decision-making roles at baseline (n=98) were active in 24 (24%), collaborative in 47 (48%), and passive in 27 (28%). There was concordance between preferred and actual decision-making roles at baseline (p=0.4). Preferring a more active role was associated with university education (p=0.02, OR 2.9) and worse HRQL during ACT: physical well-being (p=0.05, OR 4.4), overall well-being (p=0.02, OR 5.5), sleep (p=0.03, OR 8.4) and shortness of breath (p=0.01, OR 7.6). Patients who preferred an active decision-making role judged larger survival benefits to make ACT worthwhile than patients who preferred a passive role (eg extra survival time of 1 year v 6 months, WRS p=0.03; extra survival rate of 17.5% v 2.5%, WRS p <0.01).
Patients with recently resected NSCLC varied in their preferred roles in decision-making about ACT with most patients preferring a collaborative role. Their preferences were stable over time, and were concordant with their perceived actual role in decision-making at baseline. Preferences for an active role in decision-making were associated with judging larger survival benefits necessary to make ACT worthwhile. Clinicians should elicit and consider patients’ preferences for involvement in decision-making when discussing ACT for NSCLC.
