Post-op Acetaminophen vs NSAID Use on Lumbar Spinal Fusion Outcomes

Measure the impact of treatment on total opioid use during the hospital stay

Track opioid use after discharge for the first 4-6 weeks

Track opioid use after discharge for the first 3 months; assess for continued opioid use

Track opioid use after discharge for the first 1 year; assess for continued opioid use

Track total opioid use after discharge for the first 2 years; assess for continued opioid use

Validated pain scale; will be completed by patient Minimum Score: 0 \& Maximum score 100 A lower score is representative of a low pain level

The Brief Pain Inventory (BPI) is a self-administered questionnaire for chronic pain conditions. The BPI gives two main scores: a pain severity score and a pain interference score. The pain severity score is calculated from the four items about pain intensity. Each item is rated from 0, no pain, to 10, pain as bad as you can imagine, and contributes with the same weight to the final score, ranging from 0 to 40. The pain interference score corresponds to the item on pain interference. The seven sub-items are rated from 0, does not interfere, to 10, completely interferes, and contributes with the same weight to the final score, ranging from 0 to 70. The first item, pain drawing diagrams (painful and most painful areas) and the items on pain relief treatment or medication (list of the treatments and amount of relief) do not contribute to the scoring.

Ileus, nausea/vomiting, first bowel movement, first flatus, treated pruritis will be identified and recorded

The Veterans RAND 12 Item Health Survey (VR-12) is a brief, generic, multi-use, self-administered health survey comprised of 12 items. The instrument is primarily used to measure health related quality of life, to estimate disease burden and to evaluate disease-specific benchmarks with other populations. The 12 items in the questionnaire correspond to eight principal physical and mental health domains including general health perceptions; physical functioning; role limitations due to physical and emotional problems; bodily pain; energy-fatigue, social functioning and mental health.. The 12 items are summarized into two scores, a "Physical Health Summary Measure {PCS-physical component score}" and a "Mental Health Summary Measure {MCS-mental component score}". Score range is 0 to 100, higher score denotes a better outcome. This score range apply to both PCS and MCS.

The Oswestry Disability Index (ODI) is the most commonly used outcome-measure questionnaire for low back pain in a hospital setting. It is a self-administered questionnaire divided into ten sections designed to assess limitations of various activities of daily living. Each section is scored on a 0-5 scale, 5 representing the greatest disability. The index is calculated by dividing the summed score by the total possible score, which is then multiplied by 100 and expressed as a percentage. Thus, for every question not answered, the denominator is reduced by 5. If a patient marks more than one statement in a question, the highest scoring statement is recorded as a true indication of disability.
