Dr Fischbein claims that our criticism of planned home birth from the perspective of the professional responsibility of obstetricians does not succeed. Ethical analysis of planned home birth, like ethical analysis of all topics in obstetric and medical ethics, should be both evidence-based and argument-based.

On the topic of patient safety, Dr Fischbein states that the need for transport can be predicted in “experienced hands” but provides no documentation for this claim. The Birthplace in England study reported on transport rates as high as 45%. Dr Fischbein bears the burden of proof to identify evidence-based criteria for the reliable prediction of the need for transport and fails altogether to meet this professional obligation. He then states that “pain relief and prolonged labor” do not indicate unsafe clinical conditions, again without supporting documentation. The claim that the experience in another country does not apply in the United States requires Dr Fischbein to demonstrate the disanalogy, which he does not do.

Dr Fischbein states that a cesarean delivery rate in the hospital setting of 24% results in an unacceptable increased morbidity when compared to the out-of-hospital cesarean delivery rate of 6%. As applied to planned home birth, the claim is absurd, inasmuch as cesarean deliveries are not performed in the home setting. Even if the comparison were not absurd, simply reporting the rates of a procedure in the absence of outcomes data does not count as evidence-based reasoning. Worse, the paper that Dr Fischbein cites provides outcomes data on care in birth centers. Planned birth at home, the focus of our paper, is not planned birth at a birth center. The outcomes in the latter cannot be represented as the outcomes of the former. The disanalogy is obvious–and egregious.

Regarding patient satisfaction, our point in citing the Dutch experience was–and remains–that in one of the most highly developed home birth systems in the world there are significant rates of failure to achieve patient satisfaction. A dissatisfaction rate of 17% is high per se and therefore intrinsically clinically significant. Asserting the obvious corollary of 83% satisfaction should be read for what it is: an attempt to distract the reader from a substantial, documented problem with planned home birth. Dr Fischbein then states that he disagrees with national efforts to improve the homelike setting of hospital delivery without any supporting reasons. Asserting conclusions in the absence of supporting reasons is what Plato–long ago–had Socrates in the Dialogues characterize as “mere opinion,” which never counts as argument-based reasoning.

As to cost-effectiveness, we emphasized that analyzing the cost of home birth by comparing charges for home birth to charges for hospital birth is incomplete and therefore potentially misleading. Dr Fischbein’s invocation of relative costs of vaginal vs cesarean delivery does not address relative overall cost. His claims about comparative cost are therefore incomplete and misleading.

As to women’s rights, Dr Fischbein invokes the ethical analysis of vaginal birth after cesarean delivery by Charles, who argues that the autonomy of pregnant women is justifiably constrained by the professional judgment of obstetricians about what is medically reasonable. Dr Fischbein neglects to inform his reader that Charles bases her argument explicitly on our approach to obstetric ethics. Having rejected our approach (albeit without any supporting argument), Dr Fischbein invokes a paper based on it. Dr Fischbein succeeds in both deceiving his reader and violating the principle of noncontradiction. This principle forbids simultaneously holding a proposition and its denial to be true and is therefore a disabling mistake in both evidence-based and argument-based reasoning.

Planned home birth is a serious topic in obstetric ethics. Judgments about its ethical acceptability must therefore be deliberative–explicitly appealing to the results of evidence-based and argument-based reasoning. Dr Fischbein’s letter does neither and therefore makes no serious contribution to how obstetricians should understand their professional responsibility concerning planned home birth.
