Arthroscopic meniscectomy for degenerative meniscal tears reduces knee pain but is not cost-effective in a routine health care setting: a multi-center longitudinal observational study using data from the osteoarthritis initiative.

OBJECTIVES: It is disputed whether arthroscopic meniscectomy is an (cost-) effective treatment for degenerative meniscus tears in day-to-day clinical practice. The objective of this study was to assess the cost-effectiveness of arthroscopic meniscectomy in subjects with knee osteoarthritis, in routine clinical practice, while taking into account the increased risk for future knee replacement surgery. We compared cost-effectiveness of arthroscopic meniscectomy compared to no surgery. DESIGN: We used a state transition (Markov) simulation model to evaluate the cost-effectiveness of arthroscopic meniscectomy compared to no surgery in subjects with knee osteoarthritis (age range 45-79 years). Data used in the preparation of the current study were obtained from the Osteoarthritis Initiative (AOI) database. We applied a 9 years' time horizon (which is equal to the current OAI study follow up period), and evaluated cost-effectiveness from a societal perspective. The main outcome measure was the incremental cost-effectiveness ratio (Euros per quality adjusted life-year (QALY) gained). RESULTS: Arthroscopic meniscectomy was associated with 8.09 (SD ± 0.07) QALYs at a cost of € 21,345 (SD ± 841), whereas the no surgery was associated with 8.05 (SD ± 0.07) QALYs at a cost of € 16,284 (SD ± 855). For arthroscopic meniscectomy, the incremental cost per QALY gained was € 150,754. CONCLUSIONS: In day-to-day clinical practice, arthroscopic meniscectomy in subjects with knee osteoarthritis is associated with € 150,754 per QALY gained, which exceeds the generally accepted willingness to pay (WTP) (range € 20,000-€ 80,000).

Quality of life after different procedures for regional control in oral cancer patients: cross-sectional survey.

OBJECTIVES: To examine health utilities in patients with cT1-2 oral cavity squamous cell carcinoma following different diagnostic and treatment modalities for the neck and to investigate the relation between shoulder morbidity and health utility. DESIGN: Cross-sectional survey. SETTING: Two Dutch hospitals. PARTICIPANTS: Four subgroups of patients with oral cavity cancer who underwent watchful waiting, sentinel lymph node biopsy, elective supraomohyoid neck dissection or therapeutic modified radical neck dissection. MAIN OUTCOME MEASURES: Patients received the EuroQol-5D-3L questionnaire and the shoulder disability questionnaire. Mean health utility, visual analogue scale and shoulder disability scores were calculated. RESULTS: A total of 181 patients (62%) returned the questionnaires. Mean health utilities, adjusted for age, gender and time since treatment were 0.804, 0.863, 0.834 and 0.794 for the watchful waiting, sentinel lymph node biopsy, supraomohyoid neck dissection and modified radical neck dissection subgroups, respectively. Mean shoulder disability scores (higher score means more shoulder complaints) for these subgroups were 8.64, 10.57, 18.92 and 33.66. Patients with shoulder complaints had a mean utility of 0.78 while patients without shoulder complaints had a mean utility of 0.90. CONCLUSIONS: This study shows that more invasive procedures appear to result in lower health utility. The high health utility for patients after sentinel lymph node biopsy supports a role for this procedure in patients with oral cancer.
