Backgroun.: South Asian.population. are vuln.rable to poor health outcomes associated with climate due to the region.s complex topography, poverty, lack of education. an. population.den.ity. Physician., bein. highly trusted members of society, can.help mitigate climate chan.e effects in.their coun.ries. Objectives: The presen. study assessed perception. of physician. from four South Asian.coun.ries (Ban.ladesh, Bhutan. In.ia, an. Pakistan.. We hypothesized that physician. from these coun.ries will be aware an. kn.wledgeable about health effects of climate chan.e. Methods: We con.ucted a cross-section.l on.in. survey of physician. between.March an. July 2022. Data of 201 physician. was an.lyzed usin. the Kruskal-Wallis test an. Dun.’s post hoc method. Results: Physician. from four South Asian.coun.ries were attun.d to the health risks associated with climate chan.e. A majority of physician. (86.6%) believed that climate chan.e would make health con.ition. in.their coun.ries more severe or frequen. (Ban.ladesh 83.3%;Bhutan.70%;In.ia 91% an. Pakistan.90.8%). The most common.health effect related to climate chan.e was illn.sses related to reduced outdoor air quality (54.3%). Common.barriers to discuss climate chan.e with patien.s from all four coun.ries were physician.’ lack of kn.wledge (stron.ly agree, 13.8%;agree 47.7%) in.how to approach the issue with patien.s, lack of time (stron.ly agree, 12%;agree, 48%) an. their perception.that patien.s were n.t in.erested in.kn.win. about climate chan.e (stron.ly agree, 8.6%;agree, 42.6%). More than.half (56.2%) of the physician. reported n. train.n. (Ban.ladesh, 51.7%;Bhutan. 80%;In.ia, 44.6%;Pakistan. 63.1%) an. approximately 30% reported less than.20 hours of train.n. (Ban.ladesh, 28.3%;Bhutan. 15.0%;In.ia, 39.3%;Pakistan. 27.7%) in.climate-chan.e-related health effects. Con.lusion.
