TITLE DEAL Shared Decision Making in psychiatric inpatient care to enhance participation and autonomy. PURPOSE AND AIMS The purpose is to investigate patients' participation and autonomy in psychiatric inpatient care and the potential of Shared Decision Making (SDM) to strengthen patients' participation in clinical decision making. PRIMARY OUTCOME: Does SDM improve patient participation? SECONDARY OUTCOMES: Does the use of SDM improve clinical outcomes (length of inpatient days, length of involuntary care, number of inpatient episodes and completed outpatient visits)? Does outcomes of SDM relate to gender, socio-economical background, severity of disease, level of function, diagnosis and compulsory/voluntary care? How does patients and doctors experience SDM in psychiatric inpatient care regarding discharge planning? What are the ethical and legal implications of practicing SDM in Swedish psychiatric care? SDM DEFINED SDM as it will be pursued in this project consists of three steps: To introduce choice. To discuss the options. To make a shared decision. SDM aims to help patients to explore personal preferences, make informed decisions and achieve active participation in the decision-making process. From the perspective of patient autonomy, SDM goes beyond mere informed consent. The practice of SDM is meant to empower the patient to active participation. METHOD SDM in psychiatric inpatient care will be evaluated in a randomized controlled trial with SDM vs treatment as usual (TAU). The decision studied is the planning of care in the process of discharge from hospital. Quantitative methodology is used to measure the level of perceived participation and clinical outcomes. The qualitative parts of the study will focus on the process of implementing SDM in inpatient psychiatric care, and to identify ethically and legally complex situations in the use of SDM. RECRUITMENT PROCESS Informed consent will be obtained from all participants. The participants will be randomized to either SDM or TAU. The randomization is conducted by slots of 40 persons per ward (20 SDM and 20 TAU) by SPSS random number series. RESEARCH QUESTIONS The primary outcome of patient perceived participation (including the decision making process) will be answered quantitatively with the questionnaires Dyadic OPTION, SURE, Collaborate and SDM-Q-9, and qualitatively with interviews by phone 3 weeks after discharge. The interviews will be audio recorded and analyzed using qualitative content analysis. Perceived participation will be measured at inclusion at the ward and after the discharge planning conversation in both the SDM and TAU group with the questionnaires. Clinical effects (secondary outcomes) will be studied by number of: inpatient days, days of compulsory care, inpatient episodes, completed outpatient visits, completed decisions and emergency visits one year after the discharge. Information will be obtained from clinical records. Clinical and social factors will be related to level of participation. Data collected: gender, level of education, severity of illness (CGI-S), level of function (GAF) and voluntary/compulsory admission at inclusion, quality of life at discharge (EQ-5D) and clinical diagnosis at discharge (clinical records). The patient-doctor decision talks will be recorded and analyzed using qualitative content analysis, focusing on ethical and legal questions. STUDY PLAN The study starts in the fall of 2019 with a short education for the doctors and staff at the wards in the form of a seminar on SDM in a recovery perspective. The written decision support, a step-by-step manual to facilitate SDM is used in role plays and simulations to prepare the staff. Patients receive an illustrated and easy-to-read information and decision guide. During 2019-2021 patients will be recruited. This will include informed consent to participate in the study, to collect clinical data from medical records (12 months in retrospect and 12 months prospective from day of discharge), to recorded decision talks and to conduct a telephone interview three weeks after discharge. Follow up data will be collected in 2021-2022, publication of results is planned in 2022. DATA ANALYSIS A power estimation based on the results of the pilot study with a power of 80% and an ? error probability of 0.05 gave a Cohens d of 0,672. G*Power was also used for an a priori estimation with a power of 80% and an ? error probability of 0.05. A Cohen´s d of 0.5 was chosen since there is a greater risk of contamination between groups in the randomized study. This gave a group size of n=53 persons needed in each group. The dropout rate in the pilot study of 50% is with adjustments and new approaches still reasonable to estimate to approximately 30%. Group sizes were estimated to n=80 persons and the total inclusion number of N=160 persons. The groups (SDM vs TAU) will be compared for difference in mean rank, using a Wilcoxon-Mann-Whitney test, regarding their perceived participation in the decision process, which is the primary outcome. For the secondary outcomes comparison between the two groups with t-tests, comparing means will include number of inpatient days, number of inpatient episodes, number of involuntary inpatients days and completed outpatient visits. For other secondary outcomes, such as the relation between patient perceived participation and social/clinical factors, a multifactor analysis will be used.
