This сase provides us with an opportunity to examine whether blood test evidence obtained by the State pursuant to a written release of medical records, independent of the implied consent statute, may be admissible at trial in an operating while intoxicated (OWI) case. The district court suppressed the defendant’s blood test after concluding that a written release of hospital records executed by the defendant was insufficient to waive the physician-patient privilege. Upon our discretionary review of the district court’s ruling, we reverse and remand for further proceedings.
I. Background Facts and Proceedings
In the early evening of February 11, 2004, Jay Demaray lost control of his car on an icy road in Bremer County. The car slid into the ditch and became immobile. After Demaray climbed out of the ditch, аnother driver lost control of his car and struck him. Demaray was injured.
Deputy Dennis Miller, of the Bremer County sheriffs office, was dispatched to the scene. He spoke to Demaray and noticed the smell of alcohol on his breath. Upon inquiry, Demaray admitted he consumed one beer. Demaray was then taken by ambulance to a hospital in Waterloo because of his injuries. Deputy Miller did not perform sobriety tests on Demaray at the accident scene, and he did not accompany Demaray to the hospital. He was the only deputy on call that evening and remained at the accident scene. However, Deputy Miller made a request for another law enforcement officer to go to the hospital to obtain a blood sample from Dema-ray.
Between 8:00 and 8:30 p.m., a deputy from the Black Hawk County sheriffs office went to the hospital to invoke implied consent. However, he was unable to see Demaray because a doctor was treating his injuries. Shortly after 11:00 p.m., Deputy Miller arrived at the hospital. Deputy Miller went to see Demaray, who was in the intensive care unit with a fractured pelvis. By that time, almost four hours had passed since he was originally dispatched to the accident scene. Deputy Miller believed it was too late to invoke implied consent, even though Demaray had not been arrested or asked to submit to a preliminary screening test. See Iowa Code § 321 J.6(2) (“If the peace officer fails to offer a test within two hours after the preliminary screening test is administered or refused or the arrest is made, whichever occurs first, a test is not required, and there shall be no revocation under section 321J.9.” (Emphasis added.)). Deputy Miller instead asked Dema-ray to give his consent for the hospital to release his medical records, which included results of a blood test the hospital performed for treatment purposes. At 11:06 p.m., Demaray signed a release form presented to him by Deputy Miller, which had been obtаined from hospital personnel. The form stated:
*62 I hereby authorize Allen Hospital to disclose and deliver to Deputy Dennis Miller the following requested information regarding Jay Edward Demaray for the purpose of accident investigation[:] ... All medical information regarding accident on 02/11/04.
I understand that I may revoke this authorization at any time.
Demaray’s medical records showed he had a bloоd-alcohol concentration of .10 when the hospital collected his blood at 8:52 p.m.
On March 1, 2004, the State charged Demaray with OWI, first offense, in violation of Iowa Code section 321J.2. Demaray filed a motion to suppress the medical records obtained by Deputy Miller. De-maray argued that the blood test results were not admissible because the blood sample was not taken in comрliance with the implied consent statute. See Iowa Code § 321 J. 11 (“Only a licensed physician, licensed physician’s assistant as defined in section 148C.1, medical technologist, or registered nurse, acting at the request of a peace officer, may withdraw a specimen of blood for the purpose of determining the alcohol concentration or the presence of a controlled substance or other drugs.” (Emphasis added.)). The State resisted the motion, arguing that the implied consent statute is not the exclusive means by which an officer can obtain blood test results in OWI cases.
The district court granted the motion to suppress. It held the blood test results were privileged, and that the consent by Demaray “did not constitute a consent” for the medical information to be used against him at trial and did not “constitute a waiver of his physician/patient privileges.” The State applied for, and we granted, discretionary review.
II. Standard of Review
‘When the admission of evidence depends on the interpretation of a statute, we review for correction of errors of law.”
State v. Palmer,
III. Merits
Our implied consent law is found in chapter 321J of the Iowa Code. “[T]he general purpose of chapter 321J ‘is to reduce the holocaust on our highways’ ” due to drunk drivers, and the implied consent law is one means to achieve this goal.
Id.
at 860-61 (quoting
Severson v. Sueppel,
To achieve this goal, chapter 321J provides authority for chemical testing of bodily substances from persons suspected of driving while intoxicated. [Section 321J.6] is known as Iowa’s implied consent law. The premise underlying implied consent is that “a driver impliedly agrees to submit to a test in return for the privilege of using the public highways.” In reality, however, the statute normally requires the express consent of the driver before a test is administered. If the driver refuses the test, the State must revoke his or her driver’s license.
Although the laudable goal of reducing deaths caused by drunk drivers сould be most easily accomplished by the State’s unfettered ability to invoke the implied consent law, the legislature has, nevertheless, placed limitations on the circumstances under which section 321J.6 applies. Only when the requirements of section 321J.6 have been met may the State make a suspected drunk *63 driver choose between chemical testing for the presence of alcohol or the loss of his or her driver’s license.

... Section 321J.6 contains the primary conditions limiting the circumstances under which Iowa peace officers may require submission to chemical testing. To rely on the implied consent authorized by section 321J.6, the State must show (1) the withdrawal of bodily substances and the chemical test were “administered at the written request of a peace officer having reasonable grounds to believe that the [defendant] was operating a motor vehicle in violation of section 321J.2” and (2) one of six specified conditions exists.
Id. at 861-62 (citations omitted; second alteration in original). The six conditions listed in the statute to invoke implied consent are:
а. A peace officer has lawfully placed the person under arrest for violation of section 321J.2.
б. The person has been involved in a motor vehicle accident or collision resulting in personal injury or death.
c. The person has refused to take a preliminary breath screening test provided by this chapter.
d. The preliminary breath screening test was administered and it indicated an alcohol concentration equal to or in excess of the level prohibited by section 321J.2.
e. The preliminary breath screening test was administered to a person operating a commercial motor vehicle as defined in section 321.1 and it indicated an alcohol concentration of 0.04 or more.
f The preliminary breath screening test was administered and it indicated an alcohol concentration less than the level prohibited by section 321J.2, and the peace officer has reasonable grounds to believe that the person was under the influence of a controlled substance, a drug other than alcohol, or a combination of alcohol and another drug. g. The preliminary breath screening test was administered and it indicated an alcohol concentration of .02 or more but less than .08 and the person is under the age of twenty-one.
Iowa Code § 321J.6(l)(a )-(g).
The second condition was applicable to Demaray. See id. § 321J.6(1)(6) (“The person has been involved in a motor vehicle aсcident or collision resulting in personal injury or death.”). However, instead of invoking implied consent procedures to obtain a blood sample, Deputy Miller used a means not included within the statute: he asked for consent to obtain the blood test the hospital had taken earlier for treatment purposes. See id. § 321J.11 (“Only a licensed physician, ... acting at the request of a peace officer, may withdraw a specimen of blood for the purpose of determining the alcohol concentration or the presence of a controlled substance or other drugs.” (Emphasis added.)); see also id. § 321J.6(1) (noting that a test under the implied consent statute “shall be administered at the written request of a peace officer ” (emphasis added)). Therefore, the first issue we face is whether section 321J.11 is the exclusive means by which law enforcement may obtain a blood sample from a defendant in an OWI case.
Section 321J. 18 seemingly answers the exclusive-means question:
This chapter does not limit the introduction of any competent evidence bearing on the question of whether a person was under the influence of an alcoholic beverage or a controlled substance or other drug, including the results of chemical tests of specimens of blood, breath, or urine obtained more than two *64 hours after the person was operating a motor vehicle.
Id.
§ 321J.18. In commenting on this section, we have said, it expresses our legislature’s intent that the chapter “not ... be construed as limiting the introduction of competent evidence bearing on whether an accused was intoxicated.”
State v. Charlson,
Nevertheless, Demaray argues that our prior case of
State v. Wallin,
We read Wallin to stand for the proposition that the statutory implied consent procedure must be followed, but only when the implied consent procedures are invoked. Thus, our holding in
Wallin
is not contrary to section
We now reiterate that the implied consent law is not the exclusive means by which the State may obtain blood test evidence from a defendant in an OWI proceeding.
See
Iowa Code § 321J.18 (“This chapter dоes not limit the introduction of any competent evidence bearing on the question of whether a person was under the influence of an alcoholic beverage .... ”). In this case, the officer did not invoke the implied consent procedures, and consequently, we do not judge the admissibility of the blood test under the standards applicable to the implied consent standards. Instead, the blоod test was obtained by means of a release of medical records. Thus, we turn to the standard described in section
“ ‘Competent evidence’ is evidence that is admissible and relevant on the point in issue.”
State v. Kramer,
Of course, evidence covered by a privilege is generally not admissible, absent a waiver.
See generally
1 John W. Strong et al.,
McCormick on Evidence
§ 72 (5th ed.1999) [hereinafter
McCormick on Evidence
]. It is undisputed that the medical records containing thе results of Demaray’s blood test were covered by the physician-patient privilege.
See
Iowa
*65
Code § 622.10(1) (codifying the privilege);
State v. Henneberry,
The physician-patient privilege may be waived by the defendant’s disclosure or consent to disclosure of the -privileged information. 1
McCormick on Evidence
§ 103, at 413;
see Eldrenkamp,
In deciding whether Demaray waived the privilege in this case by executing the written release, we first note that he does not claim he involuntarily signed the release authorizing the hospital to disclose his records to Deputy Miller. He has therefore waived the issue, and we do not address it. See Iowa RApp. P. 6.14(l)(c) (“Failure in the brief to state, to argue or to cite authority in support of an issue may be deemed waiver of that issue.”). Instead, we consider the scope of the written waiver executed by Demaray.
The district court held that Dema-ray’s releasе of his medical records did “not constitute a consent for the use of *66 medical information against him at trial,” and did not “constitute a waiver of his physician/patient privileges.” The district court relied on the broad authority given to the State under the implied consent law to obtain and use blood test results at trial as a reason to strictly limit the scope of the release to use for investigatоry purposes, not use in a subsequent criminal prosecution. We disagree with this reasoning.
First, there is no reason to limit the scope of a medical records release by a defendant because the State could have invoked implied consent procedures. Such rationale is contrary to the legislative intent expressed in section 321J.18 for the implied consent statute not to limit other compеtent evidence of intoxication, including evidence of other tests.
Second, consent to release medical records to law enforcement for investigative purposes does not preclude the use of the records in a criminal prosecution resulting from the investigation. The purpose for which medical information is released is not necessarily a limitation on the usе of the information, especially when the purpose and the use are closely related. The important focus is on the concept of confidentiality. When Demaray consented to the hospital’s release of his medical records to Deputy Miller, he destroyed the confidentiality between him and his doctor by allowing the information to be communicated to a third party.
See

McCormick on Evidence
§ 103, аt 413 (stating patient’s disclosure of the information waives the privilege);
State v. Randle,
IV. Conclusion
The procedures under the impliеd consent statute are not the exclusive means by which the results of a blood test may be obtained. Consent may be obtained independently of the statute. When Demaray *67 consented to the release of his medical records to Deputy Miller, he destroyed the confidentiality necessary to assert the physician-patient privilege. In other words, the release of the records waived the privilege. Thus, the district court erred in granting Demaray’s motion to suppress.
We therefore reverse and remand for further proceedings.
REVERSED AND REMANDED.
