Proton beam therapy and treatment for localized prostate cancer: If you build it, they will come

ED use made 17 759 visits over the study period, while the 1928 patients with frequent ED use made 12 289 visits. Ap- proximately half (49.8%) of all ED visits occurred on week- days, while BMC primary care practices were open. Most ED visits were for low-severity conditions. Comment. Emergency department use by primary care patients at an urban safety-net hospital was high, though most visits were of low severity. One possible reason for this is lack of access to primary care, 4 with few available appointments to see a PCP. While data on time to third next available appointment, a standard measure of pri- mary care access, 5 are not available for the primary care practices during the study period, other practice met- rics suggest that access may have been a problem. For example, missed primary care appointment rates were high, averaging 24.5%. High missed appointment rates are often correlated with long wait times to schedule ap- pointments. 6 In addition, monthly telephone call statis- tics show that only between 72.4% and 88.1% of patient telephone calls were answered by the primary care call center over the study period. It is possible that patients called the practices with an urgent problem, did not have their telephone call answered promptly, and decided to seek care in the ED instead. Indeed, 13% of telephone calls were abandoned by patients over the study period (patients called and subsequently hung up while they were kept on hold). The fact that nearly half of all ED visits took place during the hours of primary care clinic op- eration further suggests that appointment availability may have been an issue. In addition, a sizable minority, roughly one-fifth, of primary care is provided by residents, 7 who have limited availability when they are not in clinic. It is also possible that Massachusetts health reform has af- fected access to primary care. As newly insured patients have entered primary care in large numbers, it is pos- sible that access to primary care has worsened for other patients. Massachusetts has been a bellwether for the imple- mentation of health reform and will be a bellwether for the transformation of primary care, with the move away from fee-for-service payments and the introduction of global payments for health care. Overall ED volume has continued to increase in Massachusetts after health re- form. 8 It is unclear if changes in primary care practice and payment will be sufficient to reduce high levels of ED use among patients at an urban safety-net hospital.
