Answers✅

To determine whether sufficient evidence exists to prescribe glucosamine for a patient who
has osteoarthritis (OA) of the knee, the family nurse practitioner reviews three article
summaries. Place the article summaries in sequential order of strength of evidence from
strongest to weakest:

1. Investigators conducted a retrospective review of 1000 charts of patients who were
diagnosed with OA and had glucosamine on their medication list. The investigators assessed
the pain rating scale at the time the glucosamine was prescribed and compared this score
with the pain rating scale three months after the medication had been prescribed. They also
reviewed the progress notes and included only patients for whom clinicians stated in the
note that the patient took the medication regularly.

2. Investigators randomly assigned a group of 1600 patients with OA of the knee to receive
either a placebo or glucosamine for six months. The goal was to determine if glucosamine
and/or chondroitin treats pain related to OA of the knee and could help prevent structural
damage. The study found no benefit for pain relief for the study group compared with the
placebo group.

3. Researchers evaluated the benefit of glucosamine for osteoarthritis of the hip and/or knee
by searching MEDLINE and the Cochrane database for studies that investigated this
question. The researchers included only studies that were double-blind, placebo-controlled,
randomized trials of at least four weeks duration and tested glucosamine's effectiveness in
treating OA in the knee or hip. Fifteen studies were included in the analysis and the
investigators applied a statistical formula to evaluate these studies, giving the larger studies
more weight.
