12 GPs were invited to take part in a study in which the GPs would undertake training in out-patient techniques, to determine suitability of patients for arthroscopic surgery. The GPs would undertake to counsel the patients regarding the procedure itself and the post operative rehabilitation. They were then referred by means of a set referral form which included specific guidelines which allowed patients to be put directly onto the consultant’s waiting list. The patients would then be sent for surgery directly and be seen immediately pre-operatively by the operating consultant and consented. This group of direct access arthroscopy patients (36) were compared to a contemporaneous consecutive series of patients who had been referred in the normal manner and were undergoing operation at the time of the study period (October 1998 to April 2000. In the group of patient submitted for direct access arthroscopy three patients had improved such that when they were offered admission dates they declined. A further three patients were deemed unsuitable for direct access arthroscopy and the referral was rejected by the consultant. Two patients declined three separate admission dates and were discharged, and a final patient did not attend his admission date. This left 27 patients who were admitted for direct access arthroscopy service. Of these, one patient was cancelled pre-operatively by the consultant as she had recently been admitted for investigation of cardiac abnormalities procedure and was therefore considered unfit for day case general anaesthetic procedure. Of the 26 patients who underwent arthroscopy all were discharged home the same day, and reviewed in the out-patient clinic at six weeks, and they were asked to complete a Patient Satisfaction Questionnaire, and were discharged from further review at that time. When compared to a contemporaneous group of patients who had undergone arthroscopic surgery via the routine referral procedure, the group of patients admitted via the direct access route waited on average ten weeks (range 6 – 12) from GP consultation and referral to operation date. This compared to 41 week for the combined total out-patient and in-patient waiting times for the routine access group (range 18 – 132 weeks). Findings at arthroscopy were similar in the two groups with mostly meniscal lesions (18/26 direct access group compared to 15/26 routine access group). The therapeutic operation rate, i.e. procedures beyond simple diagnostic arthroscopy were undertaken, was high in both groups, 68% of the direct access group and 72% of the routine access group. Pre-operative diagnosis accuracy by the GPs was significantly higher in the direct access group of referrals. 65% of direct access referrals had the correct diagnosis made by the GP in the referral compared to 18% of correct diagnosis in the group undergoing routine referrals. Post operative recovery in terms of return to work , return to activities of daily living and discharge from clinic was the same in the two groups. Patient satisfaction was comparable in both groups. In conclusion direct access arthroscopy reduces significantly the time the surgery and the number of visits by patients to primary or secondary care physicians. GP diagnostic rates were comparable to previously reported figures for registrar/middle grade pre-operative diagnostic rates for patients undergoing knee artrhoscopy. There was a high therapeutic operation rate suggesting few, if any inappropriate procedures were undertaken. The direct access arthroscopy service requires considerable time on the part of the consultant in both setting up the study and training the GPs to a reasonable standard and monitoring referrals and undertaking pre-operative screening of patients awaiting arthroscopy. There was a high inappropriate referral rate in that only 26 patients out of the 36 referred eventually underwent arthroscopic surgery. Although feasible we feel that direct access knee arthroscopy service needs refinement if it is to continue. We intend to introduce an orthopaedic practitioner who will accept referrals from GPs and then screen patients before placing patients on the consultant’s inpatient waiting list. Also the mechanism of extra lists needs to be put in place to ensure direct access patients do not “jump the queue” of patients who are already awaiting arthroscopic surgery.
We have assessed the results of 34 simple excisions of the trapezium, with no additional soft-tissue procedures, in 30 patients. At a median follow-up of five years (2 to 22), 16 thumbs (47%) were completely painfree and a further 10 (29%) were slightly painful after use. Nineteen thumbs (56%) had no functional disability, but thumb-pinch strength was reduced by about 20%. No patient had painful degeneration at the scaphotrapezial pseudarthrosis.
