OPINION
Appellant challenges the district court’s dismissal of her medical-malpractice claim against respondent. Appellant contends that respondent’s 15- to 17-hour delay in diagnosing and treating her eye infection caused her to lose vision in one eye. Respondent moved to dismiss the action pursuant to Minn.Stat. § 145.682 (2002), contending that appellant’s expert affidavit failed to detail a chain of causation. Appellant contested the motion, arguing that respondent’s motion- was untimely under Minn. R. Gen Pract. 115.03 and the court’s scheduling order and that the expert affidavit was substantively sufficient under Minn.Stat. § 145.682. The district court determined that it had the authority to hear the untimely motion and dismissed the case, finding that appellant’s expert affidavit failed to meet the substantive requirements of MinmStat. § 145.682 and Minn. R. Evid. 702. We affirm.
FACTS
In the spring of 1999, appellant Leslie Maudsley suffered from advanced glaucoma, which caused her to ' experience impaired vision in both eyes. In April 1999, Maudsley sought treatment from respondent Jonathan E. Pederson, M.D. Peder-
On May 27, 1999, Pederson performed surgery on Maudsley’s left eye; she experienced no complications from the surgery. On June 17, 1999, Pederson performed surgery on Maudsley’s right eye. Mauds-ley was scheduled for a post-operative check-up appointment on the morning of June 28. Ten days after the surgery, on June 27, 2002, Maudsley called Pederson complaining of problems with her right eye. Maudsley and Pederson agree that Maudsley told Pederson she was experiencing pain and seeing black dots — symptoms consistent with mild and normal postoperative bleeding. But the parties dispute whether Maudsley also told Pederson she was experiencing “intense pain” and an eye “hemorrhage” — symptoms consistent with infection.
Claiming that he believed Maudsley had normal post-operative symptoms, Peder-son advised Maudsley to wait and see him at her scheduled appointment the next morning, 15-17 hours later. When she attended her appointment the next morning, Pederson diagnosed the right eye as infected and sent her to a vitreoretinal specialist, who identified the infection as streptococcal endophthalmitis. Maudsley ultimately lost all vision in her right eye. Maudsley claims that the 15- to 17-hour delay in diagnosis caused her vision loss.
Maudsley filed a complaint on May 8, 2001, claiming medical malpractice. On May 31, 2002, Maudsley submitted Dr. Harvey Rosenblum’s expert affidavit. Dr. Rosenblum’s affidavit gave the following statement on causation:
It is more likely than not that if treatment had been initiated on June 27, rather than June 28, Leslie Maudsley would not have lost the vision in her right eye. She may have suffered some impairment to that vision, but she would not have lost it totally. When infections are present, it is generally true that better outcomes are the result of earlier treatment; in fact every hour counts.
After receiving Dr. Rosenblum’s affidavit, Pederson requested that Maudsley supplement the affidavit because it lacked specific information regarding causation. On June 27, 2002, Maudsley submitted an amended affidavit, which added the following sentence: “It is more likely then [sic] not that if treatment had been initiated on June 27, 1999, that Leslie Maudsley would have recovered from the infection and had the vision she had at the time surgery was performed on June 17,1999.”
On August 8, 2002, Pederson sent Maudsley a second letter stating that the amended affidavit suffered from the same deficiency regarding causation. Seven months later, in March 2003, Pederson brought a motion, identified as a “motion in limine,” to strike Maudsley’s expert affidavit as inadequate and to dismiss Mauds-ley’s claim with prejudice pursuant to Minn.Stat. § 145.682. Pederson served notice of the motion via a letter on March 27, 2003, and served motion papers on March 31, 2003. The motion was set for hearing on April 9, 2003, the scheduled date of the pretrial conference.
Maudsley filed a response to the motion on April 7, 2003, claiming that the motion was a dispositive motion and untimely under Minn. R. Gen. Pract. 115.03 and the court’s scheduling order. Maudsley also argued that the affidavit was substantively
ISSUES
I. Did the district court err by hearing Pederson’s motion to dismiss pursuant to Minn.Stat. § 145.682 when Pederson failed to comply with the formal notice requirements for filing a dispositive motion?
II. Did the district court abuse its discretion by granting Pederson’s motion to dismiss pursuant to Minn.Stat. § 145.682?
ANALYSIS
I
Maudsley argues that the district court erred by granting Pederson’s motion for dismissal pursuant to Minn.Stat. § 145.682 (2002) because it was untimely under Minn. R. Gen. Pract. 115.03 and the district court’s scheduling order. Minn. R. Gen. Pract. 115.03 requires that a party file dispositive motions 28 days prior to the hearing; the district court’s scheduling order required that dispositive motions be heard at least ten days prior to the pretrial/settlement conference.
Under Minnesota law, a plaintiff who brings a medical-malpractice claim must file an affidavit that identifies (1) qualified experts who intend to testify; (2) the substance of their testimony; and (3) a summary of the basis for the experts’ opinions. Minn.Stat. § 145.682, subd. 4(a). Failure to comply with the affidavit requirements mandates that the district court, upon motion, dismiss the plaintiffs claim with prejudice.
Id.,
subd. 6;
Lind-berg v. Health Partners, Inc.,
The district court acknowledged that Pederson’s motion was untimely, but relying on
Lombardo v. Seydow-Weber,
Here, both parties and the district court acknowledge that although the motion was labeled as a “motion in limine,” it was, in fact, a dispositive motion to dismiss, and it did not comply with the notice requirements of either Minn. R. Gen. Pract. 115.03 or the court’s pretrial/settlement conference order. But nothing in Minn.Stat. § 145.682 prevents the district court from hearing an untimely motion. And whether or not to enforce its own scheduling order is clearly within the district court’s discretion. Moreover, in the comments to Minn. R. Gen. Pract. 115, the advisory task force explained that “[t]he time limits of [the rules of general practice] may be readily modified by the court.” Minn. R. Gen. Pract. 115.03, 1997 advisory comm. note. Accordingly,’ we conclude that the district court did not err by hearing Pederson’s motion to dismiss.
We are concerned, however, about the timing of Pederson’s motion. We recognize that Minn.Stat. § 145.682 does not prescribe time limits within which motions to dismiss must be brought. But the primary purpose of the statute is to eliminate nuisance malpractice suits. Os
lund v. United States,
II
Maudsley also contends that the district court erred by dismissing her case because her expert affidavit is substantively sufficient under Minn.Stat. § 145.682. The district court found that Maudsley’s expert affidavit failed to: (1) provide the specific details concerning the expert’s expected testimony as required by Minn. Stat. § 145.682; and (2) provide a causal link between Maudsley’s loss of vision and the defendant’s alleged delay in diagnosing streptococcal endophthalmitis.
Minn.Stat. § 145.682 was enacted by the legislature to eliminate frivolous medical-negligence lawsuits by requiring that plaintiffs file affidavits verifying that their alleged claims are well founded.
Stroud v. Hennepin County Med. Ctr.,
In cases commencing after this opinion is filed ... we will expect a more complete disclosure.... [P]laintiffs will be expected to set forth, by affidavit or answers to interrogatories, specific details concerning their experts’ expected testimony, including the applicable standard of care, the acts or omissions that plaintiffs allege violated the standard of care and an outline of the chain of causation that allegedly resulted in damage to them.
Lindberg,
Maudsley argues that her expert affidavit contained sufficient details as to causation and was similar to the expert trial testimony admitted at trial in two cases.
See Demgen v. Fairview Hosp.,
c. Had the ultrasound test been performed, it would have revealed abnormally low amniotic fluid levels (i.e., the presence of Oligohydramnios). In combination with the markedly abnormal fetal heart rate tracing, this finding would dictate the need for an immediate caesarean section.
d. In a hospital comparable to that at issue, the applicable standard of care would dictate that such an emergency caesarean section be accomplished within 53 minutes, prior to this fetus dying. The failure to have the appropriate tests completed delayed having a caesarean section performed. Failing to have the appropriate tests completed was a direct cause of the fetus’ death....
e.Had such an emergency caesarean section been timely performed, a live birth would have resulted.
(a) the paramedics played a substantial part in [Blatz’s] brain injury * * * because of the delay; (b) [ejvery second is .critical because the brain, when deprived of oxygen, is extremely sensitive; (c) there’s only a certain window within which the brain must be reperfused and reoxygenated or irreversible damage will occur; (d) the period for which the brain can be without oxygen before permanent damage occurs is five minutes; (e) if persons are resuscitated within the five-minute window, the outcome is [ujsually good, without any perceptible irreversible brain damage; and (f) the longer * * * outside [the] 5-minute window resuscitation occurs, the more irreversible brain damage occurs.
Here, Maudsley’s affidavit contained the following language:
Causation. ...
It is more likely than not that if treatment had been initiated on June 27, rather than June 28, Leslie Maudsley would not have lost the vision in her right eye. She may have suffered some impairment to that vision, but she would not have lost it totally. When infections are present it is generally the rule that better outcomes are the result of earlier treatment; in fact every hour counts. It is more likely then not that if treatmenthad been initiated on June 27, 1999 that Leslie Maudsley would have recovered from the infection and had the vision she had at the time surgery was performed on June 17,1999.
Compared with the detailed affidavits in
Blatz
and
Demgen,
the general statements in Maudsley’s affidavit are not sufficient to satisfy the strict standard for expert affidavits. The primary purpose of an expert affidavit is to illustrate “how” and “why” the alleged malpractice caused the injury.
Teffeteller,
Because our analysis of this issue is dispositive, we do not reach whether the district court erred by excluding Mauds-ley’s expert under Minn. R. Evid. 702.
DECISION
We affirm the district court’s decision to dismiss Maudsley’s ease and conclude that the district court did not err by hearing Pederson’s motion to dismiss under Minn. Stat. § 145.682. Further, because Mauds-ley’s expert affidavit failed to set forth a detailed chain of causation explaining how and why Pederson’s delay in treatment resulted in Maudsley’s loss of vision, the district court did not abuse its discretion by dismissing Maudsley’s case with prejudice. We encourage parties to bring motions to dismiss early in the proceedings so that these cases may be resolved expeditiously.
Affirmed.
