Patients undergoing surgery who have concurrent mental health or substance use disorders and receive music therapy are significantly more medically complex than their counterparts receiving standard care, according to research published in the Journal of Integrative and Complementary Medicine. The finding, from investigators at University Hospitals Connor Whole Health, underscores the need for tailored perioperative care pathways that account for comorbid psychiatric conditions.

Mental health comorbidities reshape surgical risk profiles
The University Hospitals Connor Whole Health research team identified that surgical patients with documented mental health or substance use disorders who received music therapy interventions presented with substantially higher acuity markers than those in the control group. These patients carried an elevated burden of concurrent chronic diseases, required more intensive medication management, and demonstrated greater physiological vulnerability during the perioperative window.
The distinction between the study population and standard surgical cohorts reflects an overlooked reality in perioperative medicine: clinical updates on surgical preparation rarely account for the medical complexity amplified by untreated or under-managed psychiatric illness. Patients taking psychotropic medications face altered pharmacokinetics during anesthesia, while those with active substance use disorders carry risks of withdrawal, drug interactions, and compromised wound healing.
Music therapy as a targeted intervention in complex cases
Music therapy emerged in this cohort not as a luxury amenity but as a pragmatic clinical tool for patients whose surgical outcomes were already at higher risk. The investigators found that patients receiving music therapy—typically administered pre- and post-operatively—showed engagement markers consistent with reduced anxiety and improved pain perception, though longer hospital stays persisted compared to usual care groups.
This paradox—that a therapeutic intervention correlates with extended length of stay—likely reflects case-mix rather than intervention failure. The researchers note that patients selected for music therapy were already identified as higher-risk by clinical teams, meaning the therapy was appropriately allocated to the most vulnerable populations. Access to quality and safety measures in perioperative care varies widely, and structured music therapy protocols may be concentrated in academic health systems serving more severely ill populations.
Implications for perioperative care pathways
The findings challenge assumptions that all surgical patients benefit equally from standard protocols. Clinicians preparing patients with mental health comorbidities for surgery must now consider expanded pre-operative assessment, closer anesthesia coordination for those on psychotropic medications, and post-operative monitoring that accounts for psychiatric vulnerability. The BMJ and other perioperative journals have emphasized that psychiatric-surgical caseload requires dedicated liaison psychiatry resources, yet such support remains unevenly distributed across hospital systems.
Length of stay, while appearing unfavorable in this comparison, may reflect appropriate clinical judgment rather than poor outcomes. Extended admission allowed for closer monitoring of withdrawal risk, medication adjustment, and psychosocial support—interventions that prevent readmission and serious adverse events in this high-risk group.
Patients with mental health or substance use disorders undergoing surgery demonstrate significantly elevated medical complexity markers, including higher rates of polypharmacy, chronic disease burden, and psychiatric hospitalization history, necessitating integrated perioperative care pathways that bridge surgical and psychiatric specialties.

Key takeaways
- Surgical patients with mental health comorbidities show medical complexity rates 34–78% higher across multiple markers (chronic disease, medication burden, psychiatric history) than standard surgical populations
- Music therapy in this cohort appears to serve a risk-stratification function, concentrating interventions where clinical need is highest, rather than a universal enhancement
- Extended hospital stays in the music therapy group likely reflect appropriate clinical caution for vulnerable patients rather than treatment failure, and may prevent harmful readmissions
- Perioperative protocols must integrate psychiatric assessment, psychotropic medication management, and liaison psychiatry support to optimize outcomes in this growing surgical demographic
Frequently asked questions
Why did patients receiving music therapy stay longer in hospital?
The extended length of stay likely reflects appropriate clinical complexity rather than harm from the intervention. Patients selected for music therapy were already flagged as higher-risk by clinical teams. Longer stays allowed for safer monitoring of psychiatric symptoms, substance withdrawal, and psychotropic medication adjustment—interventions that reduce serious adverse events and readmission rates in this vulnerable population.
How does mental illness affect surgical outcomes?
Mental health and substance use disorders increase perioperative risk through multiple mechanisms: altered anesthetic metabolism due to chronic medication use, physiological stress responses that complicate wound healing, reduced adherence to post-operative protocols, and withdrawal syndromes. Research in the New England Journal of Medicine confirms that psychiatric comorbidity independently predicts surgical complications, longer stays, and readmission, underscoring the need for integrated care.
Should all surgical patients with mental health conditions receive music therapy?
The study does not establish music therapy as a universal standard; rather, it demonstrates that targeted interventions work best when allocated to higher-risk patients identified through perioperative psychiatric screening. Implementation should be guided by individual clinical assessment, resource availability, and integrated pathways involving both surgical and psychiatric teams, rather than universal prescription.
As surgical populations grow older and comorbidity burden rises globally, the integration of psychiatric expertise into perioperative care is no longer optional. Health systems must invest in liaison psychiatry services, formalized screening protocols for mental health and substance use, and staff training in managing psychotropic medication interactions during anesthesia. The University Hospitals Connor Whole Health findings provide an evidence base for advocating these structural changes, particularly in resource-constrained settings where psychiatric-surgical coordination remains rare.
