RT Journal A1 Plochg T, Klazinga NS T1 SPecialization in health care JF JAMA JO JAMA YR 2012 FD May 16 VO 307 IS 19 SP 2025 OP 2025 DO 10.1001/jama.2012.3582 UL http://dx.doi.org/10.1001/jama.2012.3582 AB To the Editor: Dr Detsky and colleagues1 suggested that medical specialization may have gone too far because it leads toward escalating costs without clear benefits. However, we believe the authors could have been more firm and provocative in their conclusions. A population-based approach toward assessing the appropriateness of specialization also needs to assess the responsiveness and flexibility of the existing licensing and certification mechanisms and consider the whole health care workforce instead of just the medical profession.
