A standardized patient education class as a vehicle to improving shared decision-making and increasing access to breast reconstruction

Shared decision-making is a key component of patient-centered care and has been shown to improve patient satisfaction and quality of life. Herein, we study the impact of a standardized patient education class for prospective breast reconstruction patients on clinic efficiency, access to care, and perception on shared decision-making. The number of new patient consultations per clinic, as well as average duration of the first individual clinic encounter, was compared before and after the introduction of a standardized education class given by the senior author to all new breast reconstruction patients. To evaluate patients' perception of shared decision-making, the 9-item Shared Decision-Making Questionnaire (SDM-Q9) and the Satisfaction with Information scale of the BREAST-Q Reconstruction Module were electronically distributed among the patients and compared between the two groups. Introduction of the patient education class was associated with a significant reduction in the duration of new patient encounters compared to historic controls (31.8 min vs. 53.5 min, p<0.01) along with permitting a 43% increase in new patient visits. No differences in self-perceived patient education and autonomy were seen between class participants and historic controls in the SDM-Q9 scores (p = 0.58) and BREAST-Q scores (p = 0.14). The introducing a standardized patient education class translated into a significant reduction in the duration of individual new patient encounters, thereby increasing patient access to care, while maintaining high-quality standards of self-perceived patient education and shared decision-making.

Abstract P6-12-06: Shared decision making (SDM) in routine care treatment of breast cancer patients - A survey of patients following surgery

Abstract Introduction: The aim of shared decision making (SDM) is a treatment decision in which patients are meaningfully involved. Many preference-sensitive decisions have to be made in breast cancer treatment and little is known about the implementation of SDM. We therefore investigated the process of SDM in routine care treatment. Methods: All breast cancer patients who underwent surgery in four German breast centers between 07/2016 and 07/2018 were invited to take part. The experienced decision-making process was assessed using the German version of the 9-item SDM questionnaire (PEF-FB-9). Furthermore, satisfaction with care with focus on patient participation was assessed using the ZAPA questionnaire. PEF-FB-9 and ZAPA items were summed up and transformed into a total score ranging from 0 to 100. The higher the total score the higher the experienced degree of participation and satisfaction, respectively. Participants were asked to separately rate decision-making consultations with their inpatient hospital doctors, outpatient gynecologists, outpatient oncologists and primary care providers (PCP). In addition, satisfaction with decision, participation preferences as well as other items for the complete decision process were queried. Results: Of 1,068 approached patients, 563 with a median age of 62 (31-92) filled in the survey (response rate: 53%). 81% had breast conserving surgery, 19% mastectomy. Consultations were assessed most often for hospital doctors (n=484). Gynecologists (n=270), oncologists (n=174) and PCP (n=64) were evaluated less often. Hospital doctors (mean (M): 75, standard deviation (SD): 22) and oncologists (M: 74, SD: 22) achieved the highest PEF-FB-9 scores indicating the highest degree of SDM. Gynecologists and PCP were rated almost as good with mean scores of 71 (SD: 23) and 69 (SD: 28), respectively. The mean score for all groups of doctors was 74 (SD: 21), less than 4% of patients reported SDM scores &amp;lt;25. The values for satisfaction with decision were distributed as follows: PCP (M: 90, SD: 16), hospital doctors (M: 89, SD: 16), oncologists (M: 89, SD: 17), gynecologists (M: 85, SD: 22). Conclusions: Overall, patients reported to have experienced SDM in many situations where treatment decisions were necessary. Patients were quite satisfied with the quality of information and their participation in medical decisions. However, we do not know whether non-respondents might have had different experiences regarding their treatment decision-making.

Psychometric Evaluation of the Japanese 9-Item Shared Decision-Making Questionnaire and Its Association with Decision Conflict and Patient Factors in Japanese Primary Care.

Introduction: This study aimed to verify the internal consistency and validity of the Japanese version of the 9-item Shared Decision-Making Questionnaire (SDM-Q-9) and investigate the association among patient factors, shared decision-making experienced by patients, and patients’ decision conflict during the treatment decision process in primary outpatient settings in Japan. Methods: Patients who visited a primary care outpatient unit for the first time and completed the Japanese version of SDM-Q-9 and the Decisional Conflict Scale (DCS) immediately after consultation were included. The internal consistency of SDM-Q-9 was assessed using Cronbach’s alpha coefficient. Factor analysis and structural equation modeling were used to investigate structural construct validity. The relationship among patient-perceived experiences of shared decision-making, decision conflict, and patient factors was evaluated using correlation analysis. Results: A total of 131 patients with chronic diseases (55.0% females, 28.2% aged ≥ 70 years) were included in this analysis. Cronbach’s alpha for the Japanese version of SDM-Q-9 was 0.917, indicating a high degree of internal consistency. Confirmatory factor analysis indicated that the Japanese version of SDM-Q-9 had a one-factor structure. Spearman’s rank correlation analysis indicated that the correlation between SDM-Q-9 and DCS was −0.577 (p < 0.05), indicating a significant inverse correlation and convergent validity. Older age was positively associated with perceived support of the physician in understanding all information. Conclusions: We confirmed that the Japanese version of SDM-Q-9 was both reliable and valid for use in Japanese primary care settings. In addition, we found a clear association between shared decision-making and decisional conflict of patients.

Determinants of satisfactory patient communication and shared decision making in patients with multiple myeloma.

To identify determinants of shared decision making in patients with multiple myeloma (MM) to facilitate the design of a program to maximize the effects of shared decision making. This prospective longitudinal study recruited 276 adult patients (52% male, mean age 62.86 y, SD 15.45). Each patient completed the eHealth Literacy Scale (eHEALS), Multidimensional Trust in Health Care Systems Scale (MTHCSS), Patient Communication Pattern Scale (PCPS), and 9-Item Shared Decision-Making Questionnaire (SDM-Q-9) at baseline and the SDM-Q-9 again 6 months later. One family member of the patient completed the Family Decision-Making Self-Efficacy (FDMSE) at baseline. Structural equation modeling (SEM) was used to investigate the associations between eHealth literacy (eHEALS), trust in the health care system (MTHCSS), self-efficacy in family decision making (FDMSE), patient communication pattern (PCPS), and shared decision making (SDM-Q-9). SEM showed satisfactory fit (comparative fit index = 0.988) and significant correlations between the following: eHealth literacy and trust in the health care system (β = 0.723, P < 0.001); eHealth literacy and patient communication pattern (β = 0.242, P < 0.001); trust in the health care system and patient communication pattern (β = 0.397, P < 0.001); self-efficacy in family decision making and patient communication pattern (β = 0.264, P < 0.001); eHealth literacy and shared decision making (β = 0.267, P < 0.001); and patient communication pattern and shared decision making (β = 0.349, P < 0.001). Patient communication and eHealth literacy were found to be important determinants of shared decision making. These factors should be taken into consideration when developing strategies to enhance the level of shared decision making.

Validating patient and physician versions of the shared decision making questionnaire in oncology setting.

Background: This study investigated the psychometric properties of the 9-Item Shared Decision-Making Questionnaire (SDM-Q-9) and the 9-Item Shared Decision-Making Questionnaire–Physician version (SDM-Q-Doc) using comprehensive and thorough psychometric methods in an oncology setting. Methods: Cancer survivors (n=1783; 928 [52.05%] males) and physicians (n=154; 121[78.58%] males) participated in this study. Each cancer survivor completed the SDM-Q-9. Physicians completed the SDM-Q-Doc for each of their cancer patient. Confirmatory factor analysis (CFA) and Rasch model were used to test the psychometric properties of SDM-Q-9 and SDM-Q-Doc. Results: SDM-Q-9 and SDM-Q-Doc demonstrated unidimensional structure in CFA and Rasch model. In addition, the measurement invariance was supported for both SDM-Q-9 and SDM-QDoc across sex using the multigroup CFA. Rash analysis indicates no differential item functioning(DIF)across sex for all the SDM-Q-9 and SDM-Q-Doc items. SDM-Q-9 and SDM-Q-Doc were moderately correlated (r=0.41; P<0.001). Conclusion: SDM-Q-9 and SDM-Q-Doc are valid instruments to assess shared decision making in the oncology setting.

Psychometric properties of the Shared Decision-Making Questionnaire (SDM-Q-9) in oncology practice

Background/Objective: This study sought to assess the psychometric properties of the 9-item Shared Decision-Making Questionnaire (SDM-Q-9) in patients with resected, non-metastatic cancer and eligible for adjuvant chemotherapy. Method: A total of 568 patients were recruited from a multi-institutional, prospective, transversal study. Patients answered the SDM-Q-9 after visiting their medical oncologist who, in turn, completed the SDM-Q–Physician version. Reliability, factorial structures [exploratory factor analysis (EFA), confirmatory factor analysis (CFA)], and convergent validity of the SDM-Q-9 scores were explored. Results: SDM-Q-9 showed a clear factorial structure, compatible with a strong and replicable general factor and a secondary group factor, in patients with resected, non-metastatic cancer. Total sum scores derived from the general factor showed good reliability in terms of omega coefficient: .90. The association between patient and physician perception of SDM was weak and failed to reach statistical significance. Males and patients over 60 years of age displayed the greatest satisfaction with SDM. Conclusions: SDM-Q-9 can aid in evaluating SDM from the cancer patients’ perspective. SDM-Q-9 is helpful in studies examining patient perspectives of SDM and as an indicator of the degree of quality and satisfaction with health care and patient-physician relationship.

OP126 Shared Decision-Making Influences Patients’ Adoption Of Stents In China

Introduction:Shared decision-making (SDM) is an essential component of patient-centered care, involving communication and discussions between physicians and patients on various options to meet their health needs. This study examines the current situation of patients’ participation in decision-making in relation to the clinical application of drug-eluting stents (DES). Further, the impact of patients’ involvement in decision-making on patients' adoption of DES was analyzed, with a view to providing research outcomes to guide clinical practice.Methods:A cross-sectional study was conducted from July to December 2016 in selected hospitals in Fujian Province, Sichuan Province, and Shanghai in China. Patients with coronary heart disease completed a survey, which contained the 9-item Shared Decision-Making Questionnaire (SDM-Q-9) about satisfaction with decision-making processes, and questions on DES. Data were analyzed with cluster analysis, correlation analysis, multivariate logistic regression, and multivariate linear regression.Results:One hundred and seventy-nine patients with coronary heart disease from 15 hospitals in the three regions completed the questionnaire. There were good validity and reliability for SDM-Q-9, with Cronbach's alpha as 0.96 and intra-class correlations 0.59–0.79 (all P &lt; 0.01). Among these respondents, 42.1 percent adopted DES, 83.4 percent were supportive of SDM and 61.33 percent thought they had better communication with physicians regarding decision-making. Patients’ level of SDM involvement was found to be positively associated with their satisfaction with the decision-making process (P &lt; 0.001) and their adoption of DES (P &lt; 0.05). Also, satisfaction with shared decision-making regarding treatment was positively associated with adoption of DES (P &lt; 0.001).Conclusions:Most of the patients with coronary heart disease preferred SDM, and SDM was found to be an important predictor of patients’ satisfaction with decision-making processes and adoption of DES. Better communication between physicians and patients is needed in order to improve patients’ satisfaction and promote the appropriate use of DES technology in China.

Psychometric properties of the SDM-Q-9 questionnaire for shared decision-making in multiple sclerosis: item response theory modelling and confirmatory factor analysis

BackgroundShared decision-making is a cornerstone of patient-centred care. The 9-item Shared Decision-Making Questionnaire (SDM-Q-9) is a brief self-assessment tool for measuring patients’ perceived level of involvement in decision-making related to their own treatment and care. Information related to the psychometric properties of the SDM-Q-9 for multiple sclerosis (MS) patients is limited. The objective of this study was to assess the performance of the items composing the SDM-Q-9 and its dimensional structure in patients with relapsing-remitting MS.MethodsA non-interventional, cross-sectional study in adult patients with relapsing-remitting MS was conducted in 17 MS units throughout Spain. A nonparametric item response theory (IRT) analysis was used to assess the latent construct and dimensional structure underlying the observed responses. A parametric IRT model, General Partial Credit Model, was fitted to obtain estimates of the relationship between the latent construct and item characteristics. The unidimensionality of the SDM-Q-9 instrument was assessed by confirmatory factor analysis.ResultsA total of 221 patients were studied (mean age = 42.1 ± 9.9 years, 68.3% female). Median Expanded Disability Status Scale score was 2.5 ± 1.5. Most patients reported taking part in each step of the decision-making process. Internal reliability of the instrument was high (Cronbach’s α = 0.91) and the overall scale scalability score was 0.57, indicative of a strong scale. All items, except for the item 1, showed scalability indices higher than 0.30. Four items (items 6 through to 9) conveyed more than half of the SDM-Q-9 overall information (67.3%). The SDM-Q-9 was a good fit for a unidimensional latent structure (comparative fit index = 0.98, root-mean-square error of approximation = 0.07). All freely estimated parameters were statistically significant (P < 0.001). All items presented standardized parameter estimates with salient loadings (>0.40) with the exception of item 1 which presented the lowest loading (0.26). Items 6 through to 8 were the most relevant items for shared decision-making.ConclusionsThe SDM-Q-9 presents appropriate psychometric properties and is therefore useful for assessing different aspects of shared decision-making in patients with multiple sclerosis.

Validation of the Spanish version of the 9‐item Shared Decision‐Making Questionnaire

To translate and assess the psychometric properties of the 9-item Shared Decision-Making Questionnaire (SDM-Q-9) for measuring patients' perceptions of how clinicians' performance fits the SDM process. Cross-sectional study. Data were collected in primary care health centres. Patients suffering from chronic diseases and facing a medical decision were included in the study. The original German SDM-Q-9 was translated to Spanish using the process of cross-cultural adaptation of self-reported measures as the methodological model for Spanish translation. Reliability (internal consistency) and construct validity [exploratory (EFA) and confirmatory factor analysis (CFA)] were assessed. The final Spanish version of the SDM-Q-9 was tested in a primary care sample of 540 patients. The SDM-Q-9 presented adequate reliability and acceptable validity. Internal consistency yielded a Cronbach's alpha of 0.885 for the whole scale. EFA showed a two-factorial solution, and for the CFA, the best solution was obtained with a one-dimensional factor with the item 1 excluded, which produced the best indexes of fit. The Spanish version of the SDM-Q-9 showed adequate reliability and acceptable validity parameters among primary care patients. The SDM-Q-9 is suitable for use in Spain and other Spanish-speaking countries with similarly organized health-care systems. The use of the SDM-Q-9 may contribute to the evaluation of SDM process from the patient's perspective.
