Many Older Doctors Plan to Phase out Their Practice
The results of a new survey indicate that 48 percent of physicians between 50 and 65 years of age are planning to reduce or end their clinical practice in the next 1 to 3 years.The findings also suggest that many older physicians believe that their younger counterparts do not have the work ethic they do.
The survey,which was conducted by Merritt Hawkins&Associates,a Texas-based physician search and consulting firm,suggests that many older physicians are simply unhappy with the chan- ges that have taken place in medicine over the years.
"When Baby Boom doctors entered medicine they had control over how they practiced and the fee they charged .But the rules changed on them in mid-stream and now many are looking for a ticket out."Mark Smith,executive vice president of Merritt Hawkins&Associates,said in a state-ment.
"Our study is the only one I am aware of that examines the career plans of physicians in the 50-65 age group."This age group represents more than one-third of all physicians in the U.S. If they stop working in the coming years,it will have a"significant impact"on the overall supply of physicians,Smith told Reuters Health.
The results of the survey ,which included 1,170 respondents(调查对象),show that 24 per-cent of older physicians are planning to leave clinical practice all together in the next 1 to 3 years. Specifically,14 percent said they were planning on retiring,7 percent said they were looking for a medical job a non-patient care setting,and 3 percent said they were seeking a job in a non-medi-cal field.
For those physicians not leaving clinical practice,many said they would make changes to re- duce the number of patients they treat. For instance,12 percent said they would begin working part-time,8 percent said they planned to stop taking new patients or markedly reduce their patient load,and 4 percent expressed a desire to work on a temporary basis.
When asked about the work ethic of physicians entering practice today,68 percent of the re-spondents said that these younger doctors are not as dedicated or as hard working as physicians who entered practice 20 to 30 years ago.
Fifty-seven percent of older physicians said they would not recommend medicine as a career to their own children.Similarly,44 percent said they would not select medicine as a career if they were starting out today.
" The most ominous(不祥的)finding is that about one half of physicians surveyed plant to ei-ther abandon patient care in the next 1 to 3 years,or significantly reduce the number of patients they see."Smith said."The U .S.already is facing a widespread shortage of physicians,should ol- der,‘workhorse’physicians choose to opt out of patient care access to medical services will be fur-ther restricted."
