OPINION
Opinion by
Relators1 — corporate healthcare entities operating nursing homes, or individuals connected to those operations, in Upshur County — are defendants in four healthcare liability actions pending in the trial court since August 2003. Each action alleges negligence in care of one of four nursing home residents leading to the death of that resident. Plaintiffs filed three expert reports in each of the four cases, which, according to Relators, are substantially similar. Relators filed motions to dismiss in each of the cases based on alleged failure to file the expert report required by former Article 4590i. The trial court denied Relators’ motions to dismiss.2 In this case, we consider the petition for writ of mandamus arising from trial court cause number 545-03, the Richardson case.3
Relators challenged the adequacy of the expert reports, arguing (1) that the expert reports failed to show that the author was qualified to render an expert opinion on causation and (2) that the expert reports failed to adequately state a causal link between alleged breaches of standards of care and the death of the patient. The *852trial court denied Relators’ motions to dismiss, ruling that the expert reports were adequate. Relators seek a writ of mandamus from this Court directing the trial court to dismiss the four cases. We deny the mandamus request for the following reasons.
To be entitled to mandamus relief, a petitioner must show that the trial court clearly abused its discretion and that the relator has no adequate remedy by appeal. In re McAllen Med. Ctr., Inc., 275 S.W.3d 458 (Tex., 2008) (orig.proceeding). In their quest for mandamus relief, Relators rely heavily on language from McAllen Medical Center discussing the availability of mandamus relief in healthcare liability lawsuits governed by former Article 4590L Although in the past, one serious hurdle for those seeking mandamus relief was to establish that the right to appeal was not an adequate remedy, McAllen Medical Center stands for the proposition that parties who unsuccessfully sought dismissal under former Article 4590i did not necessarily have an adequate remedy by appeal. That conclusion depended “on a careful analysis of costs and benefits of interlocutory review.” Id. at 464; In re Prudential Ins. Co. of Am., 148 S.W.3d 124, 136 (Tex.2004) (orig.proceeding); see also In re Dep’t of Family & Protective Servs., 273 S.W.3d 637 (Tex., 2009) (original proceeding) (“Whether a clear abuse of discretion can be adequately remedied by appeal depends on a careful analysis of the costs and benefits of interlocutory review.”).
The majority opinion in McAllen Medical Center noted that, in enacting the statute, the Texas Legislature had already balanced most of the relevant costs and benefits for the judicial branch and, therefore, denying mandamus in certain cases would defeat the goal of the Legislature’s act. McAllen Med. Ctr., 275 S.W.3d at 465. The opinion also pointed out that interlocutory review of the denial of motions to dismiss based on the expert report requirements became available by statute in 2003, but the review was not made retroactive, leaving denied motions in pending cases reviewable, if at all, only by mandamus.4
McAllen Medical Center also discusses considerations that would disqualify a healthcare liability case from mandamus relief:
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.
Id. at 467.
We can see the development and application of McAllen Medical Center in the Methodist Healthcare series of cases. In 2005, the San Antonio court had denied mandamus relief on the basis that an adequate remedy by appeal existed to challenge a trial court’s denial of a motion to dismiss for failure to provide adequate expert reports. See In re Methodist Healthcare Sys. of San Antonio, Ltd., 256 S.W.3d 313 (Tex.App.-San Antonio 2005, orig. proceeding). Years later, the Texas Supreme Court disposed of that relator’s petition for mandamus relief, relying on McAllen Med*853ical Center to conclude that the San Antonio court should not have denied relief on the basis that an adequate remedy by appeal existed. See In re Methodist Healthcare Sys. of San Antonio, Ltd., 256 S.W.3d 263 (Tex.2008) (original proceeding). Having been directed to reconsider, the San Antonio court concluded that the relators failed to show that the trial court had clearly abused its discretion and denied the petition on that basis. See In re Methodist Healthcare Sys. of San Antonio, Ltd., No. 04-05-00305-CV, 2008 WL 5251357, 2008 Tex.App. LEXIS 9340 (Tex.App.-San Antonio Dec. 17, 2008, orig. proceeding) (mem.op.).
This case has been pending since August 2003 and was set for trial for February 9, 2009, only to be continued by the trial court pending resolution of this petition by this Court. This situation seems to be precisely like the cases described in McAllen Medical Center wherein appeal would be an adequate remedy. That language explained that the statutory scheme governing healthcare liability claims was intended to avoid extensive discovery and prolonged litigation in frivolous cases and noted that, in some cases — older, more extensively worked cases — mandamus review could frustrate that legislative intent. Such is the case here. Here — considering the long time the case has been pending in the trial court, the imminence of trial, and the amount of discovery that has been completed — mandamus relief could frustrate that very legislative intent.
Therefore, based on the authority of McAllen Medical Center, we hold that an appeal would be adequate remedy for the review of the trial court’s ruling on the expert reports and that, therefore, mandamus review is not available.5
We, therefore, deny the petition for writ of mandamus.
