Identifying relevant subgroups in patients with low back pain (LBP) is considered important to guide physical therapy practice and to improve outcomes. The aim of the present study was to assess the cost-effectiveness of a modified version of Delitto's classification-based treatment approach compared with usual physical therapy care in patients with sub-acute and chronic LBP with 1 year follow-up.
All patients were classified using the modified version of Delitto's classification-based system and then randomly assigned to receive either classification-based treatment or usual physical therapy care. The main clinical outcomes measured were; global perceived effect, intensity of pain, functional disability and quality of life. Costs were measured from a societal perspective. Multiple imputations were used for missing data. Uncertainty surrounding cost differences and incremental cost-effectiveness ratios was estimated using bootstrapping. Cost-effectiveness planes and cost-effectiveness acceptability curves were estimated.
In total, 156 patients were included. The outcome analyses showed a significantly better outcome on global perceived effect favoring the classification-based approach, and no differences between the groups on pain, disability and quality-adjusted life-years. Mean total societal costs for the classification-based group were
The classification-based treatment approach as used in this study was not cost-effective in comparison with usual physical therapy care in a population of patients with sub-acute and chronic LBP.
在腰痛(LBP)患者中识别相关亚组被认为对于指导物理治疗实践和改善结局很重要。本研究的目的是评估改良版 Delitto 分类治疗方法与亚急性和慢性 LBP 患者 1 年随访期间的常规物理治疗护理相比的成本效益。
所有患者均使用改良版 Delitto 分类系统进行分类,然后随机分为接受分类治疗或常规物理治疗护理。主要临床结局指标包括:整体感知效果、疼痛强度、功能障碍和生活质量。从社会角度测量成本。使用多重插补处理缺失数据。使用自举法估计成本差异和增量成本效益比的不确定性。绘制成本效益平面和成本效益接受曲线。
共纳入 156 例患者。结果分析显示,分类治疗方法在整体感知效果方面有显著改善,而在疼痛、残疾和质量调整生命年方面两组间无差异。分类组的总社会成本平均为
与常规物理治疗护理相比,本研究中使用的基于分类的治疗方法在亚急性和慢性 LBP 患者人群中不具有成本效益。
