Factors influencing willingness to participate in ophthalmic clinical trials and strategies for effective recruitment.

AIM: To explore the factors influencing individuals' willingness to participate in ophthalmic clinical trials. METHODS: A questionnaire survey was conducted from January to April 2021 among patients and their family members at Zhongshan Ophthalmic Center, Sun Yat-sen University, in Guangzhou, China. The survey gathered data on respondents' willingness, demographic and socioeconomic profiles, as well as their reasons and concerns regarding engagement in clinical trials. RESULTS: Of the 1078 residents surveyed (mean age 31.2±13.1y; 65.8% females) in Guangzhou, 749 (69.5%) expressed a willingness to participate in future ophthalmic clinical trials. Specific characteristics associated with greater willingness included a younger age, lower annual income, higher education, prior participation experience, previous ophthalmic treatment, and a better understanding of clinical trials. With the exception of age, these characteristics were significantly linked to a higher willingness. The primary barrier to participation, expressed by 64.8% of those willing and 54.4% of those unwilling, was "Uncertain efficacy". In terms of motivations, the willing group ranked "Better therapeutic benefits" (35.0%), "Professional monitoring" (34.3%), and "Trust in healthcare professionals" (33.1%) as their top three reasons, whereas the unwilling participants indicated "Full comprehension of the protocol" (46.2%) as the key facilitator. CONCLUSION: This study reveals a substantial willingness to participate in ophthalmic clinical trials and demonstrates the predictive role of demographic and socioeconomic factors. Variations in motivators and concerns between willing and unwilling participants highlight the significance of tailored recruitment strategies. Importantly, the need for and trust in healthcare professionals stand out as powerful motivations, underscoring the importance of enhancing physician-patient relationships, adopting patient-centered communication approaches, and addressing individualized needs to improve accrual rates.

The lived experiences of patients undergoing acellular porcine corneal stroma transplantation.

To explore the lived experiences of patients undergoing acellular porcine corneal stroma (APCS) transplantation, a descriptive, qualitative design was performed. A purposive sample of 13 patients who underwent APCS transplantation to treat progressive infectious keratitis were enrolled in the semi-structured, open-ended interviews. The taped and transcribed interviews were analyzed using a thematic analysis approach. Alterations in the transparency of APCS grafts were accompanied by a gradual improved visual acuity (before surgery: 1.38± 0.91 logMAR; 3mo postoperatively: 0.40±0.24 logMAR, respectively). Accordingly, in terms of lived experiences, the patients generally reported "negative" experiences before the operation and during the early postoperative period, but this was greatly improved 3mo after surgery. Four main themes were derived: anxiety and fear, stigma, lifestyle change, and gratitude and insights. Conclusively, health care professionals should provide holistic care for patients, proactively promoting patients' physical and mental health.
