Abstract

 

BACKGROUND:

 

The effect of the preoperative exposure to controlled substances such as benzodiazepines and sedative/hypnotics on prolonged opioid consumption after hand surgery is not known.

 

QUESTIONS/PURPOSES:

 

(1) Is preoperative exposure to benzodiazepines and sedative/hypnotics associated with greater numbers of filled postoperative opioid prescriptions after hand surgery? (2) Is a positive history of the use of more than one controlled substance, a mood disorder, or smoking associated with greater numbers of filled opioid prescriptions after surgery? (3) Is preoperative exposure to opioids associated with greater numbers of filled postoperative opioid prescriptions after hand surgery?

 

METHODS:

 

Patients undergoing upper extremity surgery at one academic outpatient surgical center were prospectively enrolled. The Pennsylvania Drug Monitoring Program (PDMP) website was used to document prescriptions of opioids, benzodiazepines, and sedative/hypnotics filled 6 months before and after the procedure. Patients were grouped into exposed or naïve cohorts depending on whether a prescription was filled 6 months before surgery. Smoking history (current or previous smoking was considered positive) and a history of mood and pain disorders (as noted in the medical history), were collected from the outpatient and the operating room electronic medical record.

 

RESULTS:

 

After controlling for age, gender, and other confounding variables, we found that a history of exposure to benzodiazepines is associated with a greater number of filled postoperative opioid prescriptions (not-exposed, 1.2 ± 1.3; exposed, 2.2 ± 2.5; mean difference, 1.0; 95% confidence interval [CI], 0.5-1.5; p < 0.001); likewise, exposure to sedative/hypnotics is associated with greater opioid prescription fills (not-exposed, 1.2 ± 1.4; exposed, 2.3 ± 2.9; mean difference, 1.1; 95% CI, 0.3-1.9; p = 0.006). Patients who had used more than one controlled substance had more filled opioid prescriptions when compared with those not using more than one controlled substance (3.9 ± 3.5 versus 2.1 ± 1.2; mean difference, 1.8; 95% CI, 0.8-2.8; p = 0.002); patients with mood disorders also had more filled prescriptions when compared with those without mood disorders (2.0 ± 2.5 versus 0.9 ± .8; mean difference, 1.1; 95% CI, 0.7-1.5; p < 0.001); and finally, smoking history is associated with more filled prescriptions (1.9 ± 2.3 versus 1.2 ± 1.5, mean difference, 0.8; 95% CI, 0-1.4; p = 0.040).

 

CONCLUSIONS:

 

Patients exposed to benzodiazepines and sedative/hypnotics have prolonged use of opioids after surgery. Undergoing outpatient upper extremity surgery and being prescribed an opioid did not change the patterns of controlled substance use. Based on the results of this study, we are now more aware of the potential problems of patients with exposure to controlled substances, and are more attentive about reviewing their history of substance use in the PDMP website, an important resource. In addition, we now provide much more detailed preoperative counseling regarding the use and abuse of opioid medication in patients with exposure to benzodiazepines, sedatives, and those with a smoking history and mood disorders.Level of Evidence Level II, therapeutic study.

Well they were presumably prescribed (sadly) for a reason in the months pre op.

Possibly for sleep if in pain etc.

But fascinating little study.

I don’t think opioids are used much over here post op, I never had any after total hip replacement, was told to buy ibuprofen and paracetamol. @))) And yes it hurt. They let me have my pregabalin and put a line through diazepam. Glad only in two nights!,

Uk is a tad short of cash at the moment.
