Development and pilot-testing of patient decision aid for use among Chinese patients with primary open-angle glaucoma

Factors Influencing Participation in Shared Decision-Making Among Patients with Glaucoma in China: A Cross-Sectional Study

Purpose

To explore the level of participation in shared decision-making by patients with glaucoma and identify influencing factors, to subsequently provide references to promote shared decision-making in ophthalmology, and achieve patient-centered care.

Patients and Methods

A questionnaire was completed by 148 patients with glaucoma who had been admitted to a specialized ophthalmic hospital in China, between October 2021 and January 2022. The participants' responses to the nine-item Shared Decision-Making Questionnaire (SDM-Q-9) and a general information survey were analyzed to determine their level of participation in shared decision-making and influencing factors. Multiple linear regression was used to identify factors that influence shared decision-making at the time of clinical practice.

Results

The mean score of SDM-Q-9 was 71.73±21.27 (n=140). Multiple linear regression analysis showed that patients with negative attitudes towards participation in decision-making (P=0.023) and those who had rural insurance (P=0.017) had significantly lower SDM-Q-9 scores than those with positive attitudes and those with medical insurance. Patients who were more satisfied with their medical service had higher SDM-Q-9 scores (P<0.05).

Conclusion

Patients with glaucoma presented a high level of shared decision-making. Patients' attitudes towards participating in decision-making, the payment method of medical expenses, and the level of satisfaction with medical services are factors that influence their level of participation in shared decision-making.

Randomized Control Trial of the Impact of Patient Decision Aid Developed for Chinese Primary Open-Angle Glaucoma Patients

INTRODUCTION

Patient decision aid (PDA) is a tool to prompt shared decision-making. The aim of this study was to evaluate the impact of a PDA on Chinese primary open-angle glaucoma patients.

METHODS

All subjects were randomized into control and PDA group. The questionnaires, including 1) glaucoma knowledge; 2) 8-item Morisky medication adherence scale (MMAS-8); 3) 10-item glaucoma medication adherence self-efficacy scale (GMASES-10); and 4) 16-item decision conflict scale (DCS), were evaluated at baseline, 3- and 6-month follow-up.

RESULTS

Totally, 156 subjects participated in this study, including 77 in the control group and 79 in the PDA group. Compared to the control group, PDA group showed around 1 point more improvement in disease knowledge at both 3 and 6 months (both p < 0.05), 2.5 (95% CI: [1.0, 4.1]) and 1.9 (95% CI: [0.2, 3.7]) points more improvement in GMASES-10 at 3 and 6 months, respectively, and reduction in DCS by 8.8 (95% CI: [4.6, 12.9]) points more at 3 months and 13.5 (95% CI: [8.9, 18.0]) points more at 6 months. No difference was detected in MMAS-8.

CONCLUSION

PDA led to improvement in disease knowledge and self-confidence in medication adherence and reduced decision conflict compared to control group for at least 6 months.

Health literacy and ophthalmology: A scoping review

As of 2020, it is estimated that 43.3 million people are blind, and an additional 553 million have mild to severe vision impairment.⁵⁰ At least 1 billion worldwide have a vision impairment that could have been prevented or has yet to be addressed.⁵⁴ Poor health literacy may be a significant contributor to the prevalence of eye disease. With implications on disease burden, progression, and health outcomes, a greater understanding of the role health literacy plays in ophthalmology is needed. This is the first scoping review to assess the impact of health literacy on eye health outcomes and blindness, including ocular screening rates and/or follow-up rates, treatment adherence, and self-care practices. PubMed, Embase, and CINAHL databases were searched systematically through November 12, 2021, and we evaluated the association between health literacy and ophthalmic outcomes in 4 domains: clinical outcomes, treatment adherence rates, screening and/or follow-up rates, and self-care practices. There is evidence to suggest that health literacy is associated with ophthalmic outcomes in all these domains. To better understand how health literacy impacts eye health, further longitudinal studies examining the effect of health literacy (using standardized health literacy measures) on ophthalmic outcomes are needed. We believe a specific ophthalmic health literacy survey could help achieve this goal and help target interventions to ultimately improve outcomes among ophthalmology patients.

Encounter glaucoma decision Aid trial

PURPOSE

A decision aid facilitates patient engagement in the decision-making process in ophthalmic practice. In particular, patients with open-angle glaucoma will benefit from such an intervention as it enhances their knowledge, compliance, and satisfaction with the healthcare services.

METHODS

The Encounter Glaucoma Decision Aid (GDA) was delivered to 145 patients with open-angle glaucoma at the King Khaled Eye Specialist Hospital. Evaluation was done using a pre-validated, semi-structured questionnaire. We compared the patients' knowledge, compliance, and decision conflict scale at baseline, before receiving Encounter GDA, and again three months later.

RESULTS

The average age of the participants was 56.82 years. Most of the participants were male (67.6%). The mean duration since the participants were diagnosed with glaucoma was 9.39 years. After using Encounter GDA, 80% of participants had a statistically significant improvement in their level of knowledge, moving from poor to good (P = 0.001). There was also a statistically significant increase in adherence to medication, from 41.4% to 65.5% (P = 0.001). The decision conflict score decreased significantly after using Encounter GDA (before it was 60.94 ± 21.60 vs. after 19.18 ± 17.83).

CONCLUSION

Using GDA cards as an educational measure has a significant effect on improving patient's knowledge and adherence to medications.

Development and Validation of Nutrition Literacy Assessment Instrument for Chinese Pregnant Women

The study was designed to develop and validate the nutrition literacy assessment instrument for pregnant women in China (NLAI-P). The dimension, components and questions of NLAI-P were identified via literature review and expert consultation. A panel of experts evaluated the content validity. The construct validity was evaluated by using the exploratory factor analyses (EFA) and confirmatory factor analyses (CFA). Cronbach’s α coefficient and split-half reliability were applied for examining the reliability. The NLAI-P was divided into 3 dimensions including knowledge, behavior and skill dimension. Findings showed NLAI-P possessed the satisfactory content validity (content validity index = 0.98, content validity ratio = 0.97), acceptable construct validity (χ2/df = 1.82, GFI = 0.86, AGFI = 0.84, RMSEA = 0.046) and good reliability (Cronbach’s α coefficient = 0.82). The average scores of NLAI-P were 46.59 ± 9.27. With the adjustment of confounding factors, education level presented a significantly positive correlation with NLAI-P scores. In conclusion, NLAI-P were valid and reliable to inspect NL level of pregnant women in China. Poor NL was prevalent among Chinese pregnant women. Based on the education level, taking targeted propaganda and education measures would achieve the optimal effect. NLAI-P can be applied as the tool for monitoring and assessing NL of pregnant women, and facilitate the designation of targeted interventions policies.

Shared Decision Making in Ophthalmology: A Scoping Review

PURPOSE

Shared decision making (SDM) has been associated with improved patient satisfaction and outcomes in both medical and surgical specialties, but its role in ophthalmology has not been systematically examined. Using a scoping review of the literature, the purpose of this study was to explore the characteristics, implementation, and outcomes of SDM in ophthalmology.

DESIGN

Scoping review of the literature.

METHODS

Searches were conducted in PubMed, Embase, Web of Science, and the Cochrane Central Register of Controlled Trials through August 2021 for SDM in ophthalmology. The resulting 1602 studies were screened by 2 independent reviewers with 57 full-text articles examined for inclusion of an ophthalmologic diagnosis, as well as discussion of SDM or patient decision aids. Nineteen studies were eligible and qualitatively coded for 11 predetermined codes, which included patient outcomes, patient and physician requests for SDM, and methods of implementation.

RESULTS

Of 19 included studies, all emphasized the value of SDM for ophthalmology and 2 studies reported improved patient outcomes. The most commonly examined topics were chronic ophthalmic diseases, such as cataracts and glaucoma. Limitations to SDM implementation were also universally discussed, including patients' lack of disease knowledge, communication barriers, and time restrictions. Although patient decision aids are an effective tool to mitigate these limitations, these have only been established for the subjects of cataracts and glaucoma.

CONCLUSION

SDM is a methodology for patient-centered care that is regarded as a potentially useful tool in the field of ophthalmology. However, significant barriers exist to its effective implementation. Evidence-based research on if and how these barriers should be attenuated, as well as the development of additional patient decision aids for different ophthalmic diseases, are needed.

Development and Pilot-Testing of a Patient Decision-Making Aid for Nutrition in Age-Related Macular Degeneration

OBJECTIVE

We described the development and pilot-testing of an application based patient decision-making aid (PDA) for nutrition in age-related macular degeneration (AMD). Alpha-testing and beta-testing were performed to explore the PDA's usability, acceptability, and comprehensibility in the design stage and in "real-life" conditions.

METHODS

A nutrition PDA was developed in this study by a multidisciplinary steering committee that consisted of ophthalmologists, nurses, nutritionists, and methodologists using a systematic development process. The PDA was based on a smartphone native installation and a free-to-use app. First, based on information from literature reviews and focus group interviews for needs assessment, we developed a decision aid prototype. Second, we conducted the alpha testing to explore the acceptability, usability, and comprehensibility of the PDA prototype among 18 AMD patients. Third, a before/after study was conducted to assess changes in the attitudes, risk perceptions, intentions, knowledge, decisional conflicts, and decision self-efficacy of 33 AMD patients.

RESULTS

The alpha test proved that the nutrition PDA is acceptable and usable. In the beta test, after the AMD participants used the PDA, their scores for knowledge [mean = 13.3, standard deviation (SD) = 2.92], attitude (mean = 18.97, SD = 2.19), decision self-efficacy (mean = 23.94, SD = 6.04), and preparation significantly increased (mean = 26.30, SD = 4.90), and their score for decisional conflict significantly decreased (mean = 10.15, SD = 3.66). There was no significant difference in anxiety (mean = 2.64, SD = 1.08) before and after the use of the PDA. The mean score in the system usability scale was above 70 (mean = 72.61; SD = 5.38), which indicates the good usability of the PDA. With regard to the PDA acceptability, the scores for satisfaction with its comprehensibility, satisfaction with its attractiveness, and satisfaction with its emotional support were 5.49 (SD = 1.03), 5.30 (SD = 1.40), and 4.91(SD = 1.07), respectively, which show its adequate acceptability.

CONCLUSION

Our study showed that the nutrition PDA was an acceptable and suitable instrument for AMD patients and fit the values of all its stakeholders. This study is an important step in supporting shared decision-making, which has the potential to provide a more patient-centered and value-based nutrition health system for individuals with different types of AMD.

Development of a Patient Decision Aid to Help People Living with Inflammatory Bowel Disease

BACKGROUND: Patient decision aid (PDA) is a tool, which helps the improvement of shared decisionmaking and is a part of the paradigm shift from physician-centered decisions to patient-centered shared decision making. In this study, we aimed to describe the process used to develop a PDA for facilitating shared decision-making about treatment in patients with inflammatory bowel disease (IBD) who need medication (corticosteroid, azathioprine, anti-TNF, and infliximab) or surgery. METHODS: The development process of PDA included: 1) The development of a prototype based on literature review and interview 2) 'Alpha' testing with patients and clinicians 3) 'Beta' testing in real conditions and 4) The production of a final version. This process took about 12 months (2019-2020). The participants were adult patients with IBD, gastroenterologists, and nurses. RESULTS: The final PDA contains four important sections: 1) Introduction about IBD disease, the purpose of developing PDA, and emphasis on shared decision-making 2) Benefits and risks of main medicines 3) The success rate as well as the incidence of complications after surgery, and 4) The conclusion about patients' satisfaction with PDA to choose the treatment options. Besides, PDA evaluation in the real world setting showed that 100% of physicians (n=4) and 86% of patients (n=12) were completely satisfied with the content of the PDA and considered it applicable and useful. CONCLUSION: This PDA can help patients participate in the shared decision-making process and select the best medical and surgical treatment methods. The feedback received from clinicians and patients showed their satisfaction with using the PDA.

Patient experience of treatment decision making for wet age-related macular degeneration disease: a qualitative study in China

OBJECTIVES

This study aimed to investigate the experience of patients with wet age-related macular degeneration (wAMD) in treatment decision-making process.

DESIGN

A descriptive qualitative study was designed by using semistructured interviews, and the data analysis was conducted with the thematic analysis approach.

PARTICIPANTS AND SETTING

A convenient and purposive sample of 21 participants diagnosed with wAMD was recruited from May 2018 to September 2018. The study was conducted in the Eye Clinic of Southwest Hospital of Army Medical University in Chongqing located in the southwest of China.

RESULTS

The mean age of the participants was 64.48 years (ranging 50-81 years), and the duration of the disease ranged from 6 months to 48 months. Four major themes were identified from the original data analysis. These themes included facing the darkness (choosing from light and darkness and living in pain), constraints on decision making (doctor-oriented decision making, inadequacy of options and time), weighing alternatives (family influence, financial burden and maintaining social function) and decision-making support (professional decision-making assistance and peer support).

CONCLUSION

This is a qualitative study attempting to explore the patient experience of treatment decision making for wAMD disease in China. Previous literature has focused on treatment effect and symptoms, rather than the individual experience and the wide contexts from a sociocultural perspective. Further studies, such as cross-sectional studies, can be used to describe the status and determine the influencing factors of decision0making process, so as to develop an impact factor model of decision making and to formulate an intervention for patients with wAMD.

Interventions to improve participation in health-care decisions in non-Western countries: A systematic review and narrative synthesis

Background

Patients' participation in medical decision making is an important aspect of patient‐centred care. However, there is often uncertainty about its applicability and feasibility in non‐Western countries.

Objective

To provide an overview and assessment of interventions that aimed to improve patients' participation in decision making in non‐Western countries.

Method

Ovid Medline, Embase, Cochrane Central Register of Controlled Trials, CINAHL, Ovid MEDLINE(R) Epub Ahead of Print, In‐Process, Other Non‐Indexed Citations, without Revisions and Daily Update and Database of Abstracts of Reviews of Effects, were searched from respective inception to February 2018. Studies were included if they (a) were randomized controlled trials, before‐and‐after studies and interrupted time series studies; (b) were conducted in non‐Western countries; (c) aimed to improve patients' participation in dyadic decision making; and (d) reported outcomes relevant to patient participation in decision making. Studies were excluded if they included children, were about triadic decision making or solely focused on information provision without reporting outcomes related to patient participation. Narrative synthesis method was used for data analysis and presentation.

Results

A total of 17 studies, 6 RCTs and 11 non‐RCTs, were included across ten countries. Intervention strategies included patient and/or provider communication skills training, decision aids and a question prompt material. Whilst most of the studies reported increased patient participation, those interventions which had provider or patient training in communication skills were found to be more effective.

Conclusion

Interventions to improve patient participation, within the context of dyadic decision making, in non‐Western countries can be feasible and effective if communication skills training is provided for health‐care providers and/or patients.
