Evaluation of Expectations and Expectation Fulfillment in Patients Treated for Trapeziometacarpal Osteoarthritis

Purpose

To determine the main reasons why patients with trapeziometacarpal osteoarthritis (TMC OA) seek treatment, their pretreatment expectations for the final outcome, fulfillment after one year, and predictors of fulfillment of the expectation.

Methods

We included 163 patients with TMC OA. They filled out questionnaires assessing expectations and functional status before and at 3, 6, and 12 months after treatment.

Results

Pain reduction was the most important reason why 65% of all patients sought treatment, whereas 17% and 13% requested treatment to improve hand function and activities of daily living, respectively. No patients considered improved appearance of the hand to be the main reason for undertaking treatment. Expectations before treatment were anticipated to be totally or mostly fulfilled by 93% of surgically treated patients and 59% of patients treated with corticosteroid injection. After one year, 77% of surgically treated patients rated their expectations as completely or mostly fulfilled, compared with 24% of patients treated with corticosteroid injections. Including all variables before treatment in a best-fit regression model, fulfillment of patients’ expectations could not be sufficiently predicted. However, with addition to the model of the outcome of pain at one year, 48% of the variance of fulfilled expectations could be accounted for.

Conclusions

Patients with TMC OA predominantly visit hand surgeons seeking treatment to reduce pain, whereas function and aesthetics have minor roles. Based on variables before treatment, no prediction can be made regarding whether expectations will be fulfilled after treatment because residual pain at one year contributes considerably to the variance in fulfilled expectations. Clinicians should assess patients’ expectations before treatment and explain realistic treatment outcomes to obtain best treatment results.

Materials and Methods

Between September 2011 and November 2012, 163 patients with radiographically confirmed TMC OA who received either corticosteroid injection or surgical treatment (trapeziectomy with ligament reconstruction and tendon interposition) were included in the study. Exclusion criteria were diseases other than TMC OA as the main condition at the time of clinical consultation, rheumatoid arthritis, concomitant surgery on other digits, legal incompetence, poor general health condition precluding study

Results

Of the 163 patients included in this analysis, 105 (64%) underwent surgery and 58 (36%) received corticosteroid injection treatment (Table 1). At one year, 94 surgical patients (89%) and 37 patients who received steroid injections (64%) were available for follow-up. In the surgical group, the MHQ pain score decreased from a mean of 65 (± 16) points before treatment to 24 (± 23) at one year (P ≤ .001), whereas patients with corticosteroid injections had before-treatment and one-year MHQ pain

Discussion

Analysis of patient expectations for treatment for TMC OA revealed that pain reduction was the most important reason why patients sought treatment, whereas improving the appearance of the hand was of minor importance. The anticipated fulfillment of expectations before treatment in the surgery group was higher than in the corticosteroid injection group. One year after initiation of treatment, more than three-quarters of surgically treated patients rated expectations to be mostly to completely

      This study shows that the pre-treatment expectation score was significantly higher in surgically treated patients with DRF. Frouzakis et al.18 demonstrated that patients treated with surgical intervention had higher pre-treatment expectations than those treated with steroid injection for trapeziometacarpal osteoarthritis, although they were not statistically compared. Their finding was consistent with ours and could be interpreted to mean that patients treated with surgical interventions may be psychologically primed to obtain better outcomes after treatment, while those treated with conservative managements may have expected their treatment to be inadequate.

      The DASH-DLV, PRWHE-DLV, and SF-12 are 3 validated questionnaires. Furthermore, the patients were asked to choose from an 8-option list indicating why they requested the operation (Table 1).17 We reported descriptive statistics as medians and interquartile ranges (IQRs) because of their nonnormal distribution, or as absolute values.

      Because the number of patients treated in our clinic during the study period exceeded 260, we included all patients treated in our clinic during the study period. Because both patients with overly high and very low expectations have been suggested to be less satisfied, we hypothesized that there might be an optimum for CEQ Expectancy Score.12,13,16,18-22 We therefore tested whether our multivariable regression model would better fit the data when a nonlinear effect of the CEQ Expectancy Score was included, using splines.

      For the latter, we analyzed the score for the dominant hand. The satisfaction questionnaire (based on previous reports on patient satisfaction after treatment of CMC thumb joint arthritis) differentiated between sides.23,24 We asked patients why they sought treatment based on 8 items: improvement of (1) thumb function, (2) thumb appearance, (3) power, (4) pain, (5) daily activities, (6) activities of leisure, (7) return to work, or (8) other.
