Development of an Acute Care Plastic Surgery Service in the Saskatoon Health Region: Effects on flexor tendon management

Prevention of postoperative adhesions after flexor tendon repair with acellular dermal matrix in Zones III, IV, and V of the hand: A randomized controlled (CONSORT-compliant) trial

BACKGROUND

Various techniques have been attempted for preventing postoperative flexor tendon adhesion, such as modification of suture technique, pharmacological agents, and mechanical barriers. However, there is no evidence of the efficacy of these methods in clinical settings. In this study, we present the long-term outcomes of a randomized prospective study in which acellular dermal matrix (ADM) was used to prevent postoperative adhesions after tendon injury in the hand.

METHODS

From January 2017 to January 2020, all patients with an acute single flexor tendon injury in hand Zones III, IV, or V were candidates. A single-digit, total tendon rupture repaired within 48 hours, from the index finger to the little finger, was included in the study. Patients were randomly allocated to either a control or ADM group. Complications and the range of movements were recorded. Functional outcomes and a patient satisfaction questionnaire were evaluated after 12 months following the tendon repair surgery. The present study is adhered to the CONSORT guidelines.

RESULTS

A total of 25 patients was enrolled in the study: 13 patients in the ADM group and 12 in the control group. According to Buck-Gramcko II criteria, the postoperative functional outcome score was 14.38 ± 1.71 in the ADM group and 13.08 ± 1.82 in the control group (P value = .0485). Patient satisfaction was recorded at 8.38 ± 1.44 in the ADM group and 7.08 ± 1.58 in the control group (P value = .0309), a significant difference. There were no differences in complications between the 2 groups.

CONCLUSION

The beneficial effects of ADM after tendon repair were confirmed by improved postoperative functional outcome at flexor Zones III, IV, and V, preventing peritendinous adhesions and acting effectively as an anti-adhesive barrier.

Implementing and evaluating the efficacy of an acute care urology model of care in a large community hospital

INTRODUCTION

We implemented an acute care urology (ACU) model at a large Canadian community hospital to determine the impacts on safe and timely care of patients with renal colic. The model includes a dedicated ACU surgeon, a clinic for emergency department (ED) referrals, and additional daytime operating room (OR) blocks for urgent cases.

METHODS

We conducted a chart review of 579 patients presenting to the ED with renal colic. Data was collected before (pre-intervention, September to November 2015) and after (post-intervention, September to November 2016) implementation of the ACU model. Secondary methods of evaluation included surveying patients and 20 ED physicians to capture subjective feedback.

RESULTS

Of the 579 patients presenting with renal colic,194 were diagnosed with an obstructing kidney stone and were referred to urology for outpatient care. The ED-to-clinic time was significantly lower for those in the ACU model (p<0.001). Furthermore, the ACU clinic resulted in significantly more patients being referred for outpatient care (p=0.0004). There was also higher likelihood that patients would successfully obtain an appointment post-referral (p=0.0242). The number of after-hours and weekend surgeries decreased significantly after dedicated ACU daytime OR blocks were added in September 2015 (p<0.0001). All surveyed patients rated the care as either "excellent" or "very good," and all physicians believed the ACU model has improved patient care.

CONCLUSIONS

The ACU model has shown benefit in ensuring timely followup for ED patients, reducing use of after-hour OR time, and improving patient and physician satisfaction.
