The determinative question here, rather, is subjective: Did the defendants “know[ ] that [Broughton] face[d] a substantial risk of serious harm and disregard[ ] that risk by failing to take reasonable measures to abate it”? Farmer, 511 U.S. at 847, 114 S.Ct. 1970. At summary judgment, Broughton was required to “make a showing sufficient to establish the existence” of deliberate indifference, see Celotex Corp. v. Catrett, 477 U.S. 317, 322, 106 S.Ct. 2548, 91 L.Ed.2d 265 (1986), because he shoulders “the onerous burden of proving the [defendants’] subjective knowledge” at trial, see Comstock, 273 F.3d at 703.
.
To start, Broughton argues that medical staff “failed to follow the written protocols regarding the screening of inmates.” That fact, even if true, hardly establishes deliberate indifference. We have long recognized that “the right to medical care for serious medical needs does not encompass the right ‘to be screened correctly for suicidal tendencies.’ ” Id. at 702; see also Taylor v. Barkes, — U.S. -, 135 S.Ct. 2042, 2044, 192 L.Ed.2d 78 (2015) (per curiam) (“No decision of this Court establishes a right to the proper implementation of adequate suicide prevention protocols.”).
Broughton next argues that the medical staff should have been alerted to his serious risk of suicide. He bases this claim on his “complaints of withdrawal symptoms” and his “lack of access to his insomnia medication.” As we have acknowledged, “[s]uicide is a difficult event to predict and prevent and often occurs without wam-ing.” Gray v. City of Detroit, 399 F.3d 612, 616 (6th Cir. 2005). Thus, in the suicide context, a plaintiff must show that there was a “strong,” “obvious,” or “clearly foreseeable” likelihood “that he would attempt to take his own life in such a manner that failure to take adequate precautions amounted to deliberate indifference.” Id. (quoting Barber v. City of Salem, 953 F.2d 232, 239-40 (6th Cir. 1992)).
Broughton’s symptoms and behaviors did not clearly indicate a risk of self-harm. Rather, his complaints were primarily relevant to the physical indicators of withdrawal—complaints that were promptly and appropriately addressed by the medical staff. See Grose v. Carr. Med. Servs., Inc., 400 Fed.Appx. 986, 988 (6th Cir. 2010) (noting there was “no proof that [medical staff] perceived [plaintiffs] ailment as anything other than [the physical symptoms of] overuse syndrome”); Crocker ex rel. Estate of Tarzwell v. Cty. of Macomb, 119 Fed.Appx. 718, 723 (6th Cir. 2005) (per curiam) (noting that there was no evidence that the decedent “exhibited suicidal tendencies at any time between his arrest and his suicide”). The only prescription medication Broughton did not receive was Ambien, which was reasonably withheld because he admitted to abusing the drug by “snort[ing]” it. Further, even if this treatment somehow neglected Brough-ton’s risk of suicide, it is well-settled that ordinary negligence or medical malpractice cannot satisfy the subjective component of deliberate indifference: “When a prison doctor provides treatment, albeit carelessly or inefficaciously, to a prisoner, he has not displayed a deliberate indifference to the prisoner’s needs, but merely a degree of incompetence which does not rise to the level of a constitutional violation.” Comstock, 273 F.3d at 703.
Broughton goes on to argue that the defendants had general “knowledge” of his past “mental health problems.” But there is no evidence to suggest these particular defendants had actual knowledge of Broughton’s past suicidal thoughts—if anything, the record indicates that the doctors and nurses were surprised by his attempted suicide. See Grabow v. Cty. of Macomb, 580 FedAppx. 300, 304, 310 (6th
