Effects of patient satisfaction and confidence on the success of treatment of combined rheumatic disease and interstitial lung disease in a multidisciplinary outpatient clinic

Objectives Multidisciplinary discussions (MDDs) have emphasized improve medical services and outcomes. We used a multidisciplinary approach to explore whether patient emotional satisfaction and confidence affected treatment outcomes in rheumatic disease (RD)-related interstitial lung disease (ILD). Methods From December 2015 to April 2017, we evaluated 23 patients with RD and ILD and 21 with idiopathic pulmonary fibrosis (IPF). Patients with RD and ILD were managed with MDDs. Patients with IPF received standardized medical care by the same pulmonologist. All patients completed brief multiple-choice questionnaires exploring their perceptions of their illnesses and their attitudes toward medical treatment, and completed the Patient Health Questionnaire-2. Results The MDD patients could more easily identify disease symptoms regardless of age stratification (under 65 age: P = 0.020, 65 years or older: P = 0.003). Among the 65 years or older group, it shows higher levels of illness perception in terms of disease timeline in the MDD group (P = 0.035). Also, the MDD group reported higher levels of satisfaction in terms of the explanations they received and their involvement in discussion, and greater satisfaction with medical staff. However, the groups did not differ significantly between treatment outcomes such as changes in forced vital capacity, the diffusion capacity of carbon monoxide, or changes in high-resolution computed tomography. Conclusions MDDs afforded satisfactory management compared with standardized medical care. The MDD group felt better attention fromand satisfaction with medical staff, and had greater identification in their treatment. Further research engaging in MDDs with a comparable control group is required.
