RESUMO
Background Knowledge sharing is a process by which information is exchanged between peers, colleagues, or, at a higher level, between institutions and organizations. This study aimed to assess the barriers to knowledge sharing among medical students at private and public-sector medical colleges in Riyadh, Saudi Arabia. Methodology An online questionnaire was used to collect data from four medical colleges. Students were selected by non-probability convenience sampling. The English-language questionnaire included 12 questions related to knowledge sharing based on a Likert scale of one to five, with one denoting strongly disagreeing and five strongly agreeing. Out of the 520 questionnaires, 497 (96%) were received and analyzed using SPSS version 23 (IBM Corp., Armonk, NY, USA). Results A total of 497 respondents completed our questionnaire. Most were males (67.8%). Our results revealed that statements such as "afraid to provide the wrong information," "people only share with those who share with them," and "too busy/lack of time" were the most perceived barriers to knowledge sharing (mean = 3.95, 3.61, and 3.60, respectively). Furthermore, female opinions on statements such as "lack of relationship," "afraid to provide the wrong information," "do not know what to share," and "shyness to provide own opinions" were more dominant than male opinions. This difference was found to be statistically significant (p-values = 0.007, 0.020, 0.002, and 0.009, respectively). Conclusions Our study indicated that barriers such as "afraid to provide the wrong information" and "people only share with those who share with them" are important barriers that hinder the process of knowledge sharing. Moreover, most students agreed that "too busy/lack of time" and "lack of relationship" are barriers to knowledge sharing. In addition, statements such as "lack of relationship," "afraid to provide the wrong information," "do not know what to share," and "shyness to provide own opinions" were acknowledged as barriers by female students more than male students. There is a need in the curriculum to structure various types of activities that inspire and promote knowledge exchange among students. Further research is needed to validate our findings.
RESUMO
Background Among psoriatic patients, psoriatic arthritis is the most common and most impactful comorbidity. In most cases, it occurs after the onset of psoriasis. Detecting and treating it early is crucial for rheumatologists and dermatologists. Objectives The study aimed to determine the prevalence of psoriatic arthritis among recognized cases of psoriasis, as well as to determine the clinical features of psoriasis that are linked to a greater prevalence of psoriatic arthritis at King Abdulaziz Medical City (KAMC), Riyadh. Methods A retrospective cohort study of 487 psoriatic patients diagnosed between 2015 and 2023 was conducted at KAMC, Riyadh. The study included subjects aged 18 years or older with a psoriasis diagnosis documented by a dermatologist and a psoriatic arthritis diagnosis documented by a rheumatologist based on the Classification Criteria for Psoriatic Arthritis (CASPAR). Patients younger than 18 years, diagnosed with psoriatic arthritis concurrently with psoriasis, or within 90 days of psoriasis diagnosis, or who lack a documented diagnosis of psoriasis by a dermatologist were excluded. The study evaluated demographic data and medical variables concerning psoriasis (age at onset, type of psoriasis, site of psoriasis, and nail dystrophy) and psoriatic arthritis. SPSS Statistics version 25 (IBM Corp., Armonk, NY) was used to conduct statistical analysis. The p-value of 0.05 was used to evaluate statistical significance. Results Overall, 487 patients had psoriasis in this study. Of these, 49 (10%) were diagnosed with psoriatic arthritis. The mean ± standard deviation of the age of the psoriasis group was 41.7 ± 15.6 years, with 264 (54.2%) females and 223 (44.8%) males. The clinical features of psoriasis that were linked to a greater frequency of psoriatic arthritis in our study included female gender (71.4%), plaque psoriasis (95.9%), psoriatic lesions involving the extremities (75%), scalp (42.9%), and trunk (36.7%), nail dystrophy (28.6%), as well as the involvement of three or more sites (40.8%) at the time of their initial diagnosis of psoriasis. Conclusion Our study indicated that 10% of Saudi patients with psoriasis had psoriatic arthritis. Moreover, the present study shows that patients with greater psoriatic lesions at initial presentation are more likely to develop psoriatic arthritis.
