IN RE MCALLEN MEDICAL CENTER, INC., d/b/a McAllen Medical Center and Universal Health Services, Inc., Relator, 275 S.W.3d 458

Justice BRISTER delivered the opinion of the Court, in which Justice HECHT, Justice MEDINA, Justice GREEN, Justice JOHNSON and Justice WILLETT joined. Appellate courts cannot afford to grant interlocutory review of every claim that a trial court has made a pre-trial mistake. But we cannot afford to ignore them all either. Like “instant replay” review now so common in major sports, some calls are so important — and so likely to change a contest’s outcome — that the inevitable delay of interim review is nevertheless worth the wait.

Although mandamus review is generally a matter within our discretion, our place in a government of separated powers requires us to consider also the priorities of the other branches of Texas government. One of those is implicated here— repeated findings by the Legislature that traditional rules of litigation are creating an ongoing crisis in the cost and availability of medical care. To meet this crisis, the Legislature declared that plaintiffs must support health care claims with expert reports shortly after filing, something they have long had to do at trial.

This expedited deadline will of course never accomplish the purposes of the Texas Legislature unless it is enforced by Texas courts. Four years ago, this Court denied several petitions seeking mandamus relief when the statutorily required reports were allegedly inadequate. The courts of appeals have disagreed since then whether this action means that mandamus review is never available in such eases — several concluding that it does, and several concluding that it does not. We granted the petition here to settle the question.

We now hold that mandamus relief is available when the purposes of the health care statute would otherwise be defeated. I. Background The relator hospital, McAllen Medical Center, granted credentials to Dr. Francisco Bracamontes to perform thoracic surgery at the hospital. Dr. Bracamontes got his medical education in Mexico, was licensed to practice medicine in Texas, and had completed a three-year fellowship at the Texas Heart Institute in Houston.

But he was not board certified in thoracic surgery, as only physicians who have completed residencies at accredited U.S. hospitals are eligible for such certification. In 1999, competing mass-tort cases involving treatment by Dr. Bracamontes were filed — one as a class action, and this case by 400 plaintiffs representing 224 former patients. As required by statute, the plaintiffs in this case submitted expert reports regarding all 224 patients, all signed by Dr. Jetta Brown. The hospital moved to dismiss on the basis (among others) that Dr. Brown was not qualified to comment on the issues here.

After sitting on the motion for four years, the trial court finally denied it. The hospital then sought mandamus relief in the Thirteenth Court of Appeals, which was denied. The hospital now requests mandamus relief in this Court. To be entitled to such relief, a petitioner must show that the trial court clearly abused its discretion and that the relator has no adequate remedy by appeal. We address each in turn. I. Clear Abuse of Discretion A. Negligent Credentialing In her initial reports, Dr.

Brown addressed a single claim against the hospital: that it had been negligent in “hiring, retention and supervision of Dr. Francisco Bracamontes.” We have held that such claims are health care liability claims. Thus, they had to be supported within 180 days of filing by an expert report signed by a person with knowledge, training, or experience concerning the applicable standard of care. The curriculum vitae the plaintiffs submitted for Dr. Brown was a model of brevity. It lists where she went to high school and college, but not medical school.

It discloses a “general surgery internship,” but not when it took place or how long it was. For employment, it shows two years practicing emergency medicine (1978-80), twenty years in solo family practice (1980— 2000), five years “specializing in medical-legal issues” (1995-2000), and a “house call business in general medicine” since 2000. It lists no hospitals where she is on staff, or has been for twenty years, though in her reports Dr. Brown says she has worked as a “surgical assistant” and attended “heart catherizations” [sic] regarding some of her patients.

There is nothing else in either the CV or the reports to suggest she has special knowledge or expertise regarding hospital credentialing. On this record, the plaintiffs have not established Dr. Brown’s qualifications. “The standard of care for a hospital is what an ordinarily prudent hospital would do under the same or similar circumstances.” Nothing in the record here shows how Dr. Brown is qualified to address this standard. Nor can we infer that she may have some knowledge or expertise that is not included in the record.

Moreover, “a negligent ereden-tialing claim involves a specialized standard of care” and “the health care industry has developed various guidelines to govern a hospital’s credentialing process.” Dr. Brown’s reports contain no reference to any of those guidelines, or any indication that she has special knowledge, training, or experience regarding this process. Nor was Dr.

Brown qualified merely because she is a physician; “given the increasingly specialized and technical nature of medicine, there is no validity, if there ever was, to the notion that every licensed medical doctor should be automatically qualified to testify as an expert on every medical question.” As the plaintiffs’ only reports supporting the credentialing claims against the hospital were submitted by a doctor who was not qualified for that purpose, the trial court committed a clear abuse of discretion by concluding these reports were adequate. B.

Other Causes of Action In addition to their credentialing claim, the plaintiffs pleaded that Dr. Bra-camontes was the hospital’s agent, and thus was vicariously liable for his negligence. This claim is viable only if the doctor was negligent, so it too is a health care liability claim and must be supported by an expert report. But nothing in Dr. Brown’s reports suggest the hospital controlled the details of his medical tasks (a requirement for hospital liability), and the plaintiffs do not argue otherwise on appeal.

But they do argue that even if then-expert reports were inadequate, dismissal would be improper as to their fraud, fraudulent concealment, civil conspiracy, and misrepresentation claims as these do not involve health care. Their pleadings show otherwise. The civil conspiracy they alleged was that the defendants “conspired to commit malicious physician credentialing and fraud”; the fraud, fraudulent concealment, and misrepresentations they pleaded related to “material facts regarding Dr. Bracamontes’ qualifications to perform cardiac surgery.” These are simply clandestine credentialing claims.

Finally, the plaintiffs asserted that the hospital advertised all its heart surgeons as board certified, and sought economic damages “because Dr. Braca-montes performed cardiac surgery when he was not qualified as represented, and the Defendants failed to provide the promised quality of medical services.” “Health care liability claim” does not include claims unrelated to a departure from accepted standards of medical care, health care, or safety. But as the plaintiffs’ advertising claims specifically related to whether Dr.

Bracamontes was “qualified as represented” and attacked the “quality of medical services” they received, they were inseparable from a health care claim regarding the standards of hospital care. A person cannot avoid the statutory expert-report requirements by artful pleading. As all the acts and omissions the plaintiff alleged against the hospital concerned its credentialing decision, they are governed by our conclusion above that their reports were inadequate. III.

No Adequate Remedy by Appeal Whether a clear abuse of discretion can be adequately remedied by appeal depends on a careful analysis of costs and benefits of interlocutory review. As this balance depends heavily on circumstances, it must be guided by analysis of principles rather than simple rules that treat cases as categories. The most frequent use we have made of mandamus relief involves cases in which the very act of proceeding to trial — regardless of the outcome — would defeat the substantive right involved.

Thus we have held appeal is not an adequate remedy when it will mean: • forcing parties to trial in a case they agreed to arbitrate; • forcing parties to trial on an issue they agreed to submit to appraisers; • forcing parties to a jury trial when they agreed to a bench trial; • forcing parties to trial in a forum other than the one they contractually selected; • forcing parties to trial with an attorney other than the one they properly chose; • forcing parties to trial with an attorney who should be attending the Legislature; and • forcing parties to trial with no chance for one party to prepare a defense.

In each of these cases, it was argued that no harm would come from the trial— perhaps the case would settle, and perhaps fee and interest awards could remedy the expense and delay of trying the case twice. But in each case we granted mandamus relief. Some fee and interest reimbursements are uncollectible, and some sunk costs (such as time taken from other work) are unrecoverable regardless. Further, a legal rule that no harm could possibly accrue to anyone so long as the attorneys get paid to try the case twice appears at least a little self-interested.

Of course, mandamus is generally unavailable when a trial court denies

summary judgment, no matter how meritorious the motion. But parties are not “entitled” to

summary judgment in the same way they are entitled to arbitration, their chosen attorney, or an expert report like those here.

Summary judgments were unknown at common law, and appeared in Texas cases only with adoption of the rule in 1949. Even if the merits could be decided only one way, jury trials may still be important both for justice and the appearance of doing justice. Moreover, trying a case in which

summary judgment would have been appropriate does not mean the case will have to be tried twice— as it will if the first trial is conducted in the wrong time, place, or manner. By contrast, insisting on a wasted trial simply so that it can be reversed and tried all over again creates the appearance not that the courts are doing justice, but that they don’t know what they are doing. Sitting on our hands while unnecessary costs mount up contributes to public complaints that the civil justice system is expensive and outmoded. Here, the Legislature has already balanced most of the relevant costs and benefits for us.

After extensive study, research, and hearings, the Legislature found that the cost of conducting plenary trials of claims as to which no supporting expert could be found was affecting the availability and affordability of health care — driving physicians from Texas and patients from medical care they need. Given our role among the coordinate branches of Texas government, we are in no position to contradict this statutory finding.

If (as appears to be the case here) some trial courts are either confused by or simply opposed to the Legislature’s requirement for early expert reports, denying mandamus review would defeat everything the Legislature was trying to accomplish. The plaintiffs point out that when the Legislature mandated interlocutory review of expert reports in 2003, it did not make those procedures retroactive. But the Legislature’s decision to forego interlocutory review of all pending cases in no way suggests it intended interlocutory review of none of them.

Some appellate courts had already begun reviewing such cases by mandamus before 2003, and retroactive application might have raised constitutional challenges to the statute that prospective application did not. Moreover, for cases about to go to trial in 2008, mandating interlocutory review could have slowed disposition rather than expediting it. So we disagree that the Legislature’s provision for mandatory review in future cases suggests it intended to prohibit review in cases already pending. For many of the same reasons, we acknowledge that mandamus review should not be granted in every pre-2003 case.

The statute was intended to preclude extensive discovery and prolonged litigation in frivolous cases; review by mandamus may actually defeat those goals if discovery is complete, trial is imminent, or the existing expert reports show a case is not frivolous. But if the legislative purposes behind the statute are still attainable through mandamus review, Texas courts should not frustrate those purposes by a too-strict application of our own procedural devices. Applying those principles here, we hold that appeal would not be an adequate remedy in this case.

This appears to be precisely the kind of case the Legislature had in mind when it enacted the expert report requirements. The 224 patients initially involved in this consolidated suit had nothing in common other than their doctor. The plaintiffs assert no precedent for consolidating hundreds of malpractice claims by different patients with different health problems and different courses of treatment; their only explanation is that they wanted to save money on filing fees.

The hospital promptly objected to the plaintiffs’ expert reports, but the trial judge refused to rule on the objection for four years, even though the hospital repeatedly reminded the judge and asked for a ruling in the interim. Meanwhile, the hospital’s attorneys had to attend numerous docket calls and status conferences, and moved for

summary judgment against 200 plaintiffs whose claims were barred by limitations — motions the trial court granted, but which the hospital should never have had to file. Unquestionably, the hospital could have avoided significant expense and delay had the trial court followed the law as set out in the statute; unquestionably, the hospital will continue to incur costs and delay in the future if we deny relief today. Accordingly, we hold the hospital has shown it has no adequate remedy by appeal. This holding is not (as the dissent argues) a sudden departure from Walker v.

Packer, That case was not “seminal” as it represented not the seed of Texas mandamus jurisprudence (which stretches back almost two centuries) but an effort in 1992 to prune some of its branches. The seminal case was actually Bradley v.

McCrabb, issued while Texas was still a republic, which held that mandamus was not limited to cases where there was “no other legal operative remedy,” but would issue when “other modes of redress are inadequate or tedious” or when mandamus affords “a more complete and effectual remedy.” We mentioned this “more lenient standard” in Walker, but found it unworkable as it “would justify mandamus review whenever an appeal would arguably involve more cost or delay than mandamus.” But while rejecting a standard allowing mandamus almost always, we did not adopt a standard allowing it almost never.

To the contrary, we said there would be “many situations” in which mandamus would be appropriate: Nor are we impressed with the dissenters’ claim that strict adherence to traditional mandamus standards will signal an end to effective interlocutory review for some parties or classes of litigants. There are many situations where a party will not have an adequate appellate remedy from a clearly erroneous ruling, and appellate courts will continue to issue the extraordinary writ.

In describing when an appeal would be “inadequate,” we listed several situations “[i]n the discovery context alone” that “come to mind”: • when disclosure of privileged information or trade secrets would “materially affect the rights of the aggrieved party”; •when discovery “imposes a burden on the producing party far out of proportion to any benefit that may obtain to the requesting party”; •when a “party’s ability to present a viable claim or defense at trial is vitiated or severely compromised by the trial court’s discovery error”; and • when “the missing discovery cannot be made part of the appellate record ... and the reviewing court is unable to evaluate the effect of the trial court’s error.” By mentioning these instances only as ones that “come to mind,” the Court clearly did not limit mandamus to them.

And almost immediately after Walker we began recognizing additional instances in which an appeal would be inadequate, including: •when a trial court refused to compel arbitration; • when an appellate court denied an extension of time to file an appellate record; •when a trial court refused to compel discovery until 30 days before trial; • when a trial court denied a special appearance in a mass tort case; and • when a trial court imposed a monetary penalty on a party’s prospective exercise of its legal rights.

The problem with defining “inadequate” appeals as each situation “comes to mind” was that it was hard to tell when mandamus was proper until this Court said so. So almost four years ago we tried to describe the public and private interest factors that courts should balance in deciding whether the benefits of mandamus outweighed the detriments in each particular case. There is no reason this analysis should entangle appellate courts in incidental trial court rulings any more than Walker’s ad hoc categorical approach.

For example, some privileged or confidential matters may be so innocuous or incidental that the burden of reviewing an order to produce them outweighs the benefits of such a review; in such cases, a balancing approach would prevent entanglement while Walken’s categorical approach might require it. The balancing analysis we have followed for some years now merely recognizes that the adequacy of an appeal depends on the facts involved in each case. The facts in this case do not involve delay and expense alone, as the dissent alleges.

The Legislature determined that cases like this one were rendering health care unavailable or unaffordable in areas of Texas like the one where this ease was filed. The Legislature’s insistence that plaintiffs produce adequate expert reports is almost as old as this Court’s attempt in Walker to define adequate appeals. We disagree with the dissent that this Court’s priorities should trump those adopted by the people through their legislative representatives. IV. Dismissal or Amendment?

Finally, the plaintiffs argue that if mandamus relief is granted, they are still entitled to seek an additional 30-day “grace period” from the trial court to amend their expert reports. Under the facts and statute at issue here, that option is not available. Unlike the current statute, the statute applicable before 2003 allowed a grace period to correct inadequate reports only if the inadequacy was the result of an accident or mistake: Notwithstanding any other provision of this section, if a claimant has failed to comply with a deadline established by Subsection (

d) of this

section and after hearing the court finds that the failure of the claimant or the claimant’s attorney was not intentional or the result of conscious indifference but was the result of an accident or mistake, the court shall grant a grace period of 30 days to permit the claimant to comply with that subsection. In a motion filed the morning of the hearing on their reports, the plaintiffs requested such an extension for two reasons. First, they sought an additional 30 days to get the medical records of 11 plaintiffs, none of whom remain in the case.

And as negligent eredentialing caused harm to the plaintiffs only if Dr. Bracamontes’s privileges should have been revoked before they were treated, them own medical records could not establish that claim. Second, the plaintiffs alleged that any inadequacies in their reports were the result of accident or mistake rather than conscious indifference. In Walker v. Gutierrez, we held that a report that completely omitted one of the elements required by statute could not be an accident or mistake because “a party who files suit on claims subject to

article 4590i is charged with knowledge of the statute and its requirements.” Here, the plaintiffs’ attorneys are charged with knowledge that they needed an expert in hospital credentialing, and with the qualifications (or lack thereof) of Dr. Brown. Her curriculum vitae showed she was a solo family practitioner, and revealed neither experience in hospital administration nor even staff privileges at any hospital. At the hearing on the hospital’s motion to dismiss, the trial court admitted deposition testimony by Dr. Brown that she had not had staff privileges at any hospital for several years.

On this record, the trial court would have no discretion to conclude that the plaintiffs thought Dr. Brown was qualified due to an accident or mistake. * * * Because the trial court abused its discretion in failing to grant the hospital’s motion to dismiss, we conditionally grant the writ of mandamus and order the trial court to vacate its order and enter a new order dismissing the plaintiffs’ claims against the hospital. We are confident the trial court will comply, and our writ will issue only if it does not.
