Cost Comparison of Collagenase Clostridium Histolyticum and Fasciectomy for Treatment of Dupuytren's Contracture in the Australian Health System

Collagenase clostridium histolyticum injection versus limited fasciectomy for the treatment of Dupuytren's disease: a systematic review and meta-analysis of comparative studies

INTRODUCTION

The aim of the present study is to systematically review the literature on well-selected comparative studies for meta-analysis on outcome differences between collagenase clostridium histolyticum (CCH) injection and limited fasciectomy (LF) for Dupuytren's disease.

MATERIALS AND METHODS

PubMed/Medline, Embase, and the Cochrane Library were searched for comparative studies assessing differences in outcomes of CCH and LF. Effect estimates were pooled across studies using random effects models and presented as weighted mean difference (MD) and odds ratio (OR) with corresponding 95% confidence interval (CI).

RESULTS

A total of 11 studies encompassing 1'051 patients was included (619 patients in the CCH and 432 in the LF group). The residual contracture at a minimal average follow-up of three months was higher in the CCH group than in the LF group (27.8 vs. 16.2°, MD 11.6°, 95% CI [8.7, 14.5°], p < 0.001). The recurrence rate was significantly higher in the CCH group (25.8 vs. 9.3%, OR 5.2, 95% CI [1.5, 18.8], p = 0.01) while the rate of severe complications was significantly higher in the LF group (0.3 vs. 7.3%, OR 0.12, 95% CI [0.03, 0.42], p = 0.001).

CONCLUSIONS

Evidence of the present study confirms that CCH injection has a higher rate of disease recurrence whereas LF carries a higher risk for severe complications. It's imperative that the trade-off between these aspects is considered, keeping in mind that CCH injections may be repeated in case of disease recurrence without increasing procedure related risks, especially in complex cases.

Clostridium Histolyticum Collagenase Underdosed for Multicord Injection in Dupuytren's Disease: A Retrospective Cohort Study

An underdosing of collagenase clostridium histolyticum (0.32 mg) is proposed as a potentially effective option in patients with additional cords in the same hand, after the first cord has been treated with the regular dose of 0.58 mg. The aim of this study was to analyze whether this additional dose is tolerated and effective.

METHODS

Patients with Dupuytren's disease affecting MCP joints with at least two independent pathological cords, causing deformity of two digits, were considered, with their written informed consent, for a simultaneous injection of the two cords with a single vial of collagenase. Digits treated with the standard dose of 0.58 mg were compared with digits injected with the smaller dose of 0.32 mg. Passive extension deficit and range of motion were evaluated after injection. Complications were also compared.

RESULTS

A total of 26 patients (29 hands) were included in the study. Of these, nine patients had two independent cords within one hand, and 17 patients had a single cord (three of these with a cord in each hand). Thirty-five digits were injected, 23 with 0.58 mg and 12 with 0.32 mg. Apart from a smaller mean percentage variation in passive extension deficit within 24 hours in the 0.58-mg dose compared with 0.32 mg (29% versus 40%, P = 0.031), no other differences emerged if a dose of 0.32 mg is used instead of 0.58 mg, in terms of selected outcome measures and rate of complications (P > 0.05).

CONCLUSION

Underdosing collagenase clostridium histolyticum is equally effective in the treatment of Dupuytren's disease.

Collagenase and the Treatment of Dupuytren Contracture: Efficacy of Treatment and Patient Satisfaction

Background: Collagenase clostridium histolyticum has become a widely used treatment in the management of Dupuytren disease. The aims of this study are to assess the immediate success of treatment of Dupuytren contracture with collagenase injection, to measure long-term patient-rated outcomes, to determine whether the risk factors for the disease impacted outcomes and to report complications of collagenase treatment. Methods: A prospective study was performed in a tertiary referral centre. Measurements were recorded pre-treatment, day 1 and day 90. Patient-rated outcome scores were measured using Disability of the Arm, Shoulder and Hand questionnaire (DASH) and the Michigan Hand Questionnaire (MHQ) at minimum 36 months post-injection. Results: The study included 45 patients with 53 hands with a mean age of 65.7 years. The treatment was successful in 62% of patients with the greatest improvement in the metacarpal-phalangeal joint of the little finger. Diabetes, epilepsy, gender, alcohol intake and positive family history had no statistically significant predictive value on successful outcomes. Patient satisfaction at 41 months was high with mean MHQ score of 97.3. Conclusions: Collagenase is effective in the treatment of Dupuytren contracture, with disease involving the little finger showing the greatest benefit. Risk factors for development of Dupuytren disease had no effect on successful outcome and long-term satisfaction rates are high. Level of Evidence: Level III (Therapeutic).

Dupuytren's disease: using needles more across the world

In this article we take an international perspective on the use of needles, either percutaneous needle fasciotomy (PNF) or Clostridial Collagenase Histiolyticum (CCH), in treating Dupuytren's Disease (DD). Worldwide, PNF is now used more frequently. The CCH has been withdrawn from non-USA markets, which lessens its use. Different patients have different preferences, while different surgeons have different skills and opinions. The surgeon should fully consider the patient's preference and should also, in view of the scarcity of surgical resource and the potential hazard of surgery, reconsider and expand the use of a needle rather than an operation. In the future, a cheaper, yet equally safe and effective alternative to CCH, will provide a useful clinical tool for those cords, which, in the surgeon's personal Venn diagram, are too challenging for PNF, but the patient does not want to have surgery.

Cost Analysis and National Trends in the Treatment of Dupuytren Contracture Comparing Collagenase Injection, Needle Fasciotomy, and Open Fasciectomy Procedures

BACKGROUND

Dupuytren contracture (DC) is a common disorder characterized by progressive fibrosis of palmar fascia. This study analyzed cost trends of 3 common treatments for DC: fasciotomy, fasciectomy, and collagenase injection (CI)/cord manipulation.

METHODS

The Vizient Clinical Data/Resource Manager electronic database was reviewed for all procedures for the treatment of DC at participating hospitals in the United States (US) from October 1, 2015, to September 1, 2019. Cases were placed into 1 of 3 categories: (1) CI, (2) needle fasciotomy (NF), and (3) open fasciectomy (OF). Total and direct costs were averaged for each procedure and compared nationally and regionally. Temporal trends and specific market share were analyzed. One-tailed t test and Pearson correlation analysis was performed (P < 0.05 and r > 0.9 or r < -0.9 was considered significant).

RESULTS

A total of 22,974 total cases were identified. A total of 16,966 OF, 3962 NF, and 2046 CI were performed. There was a nearly a 4-fold increase in number of procedures to treat DC from 2015 to 2018. Market share percentage of each procedure stayed relatively similar over time. However, market share percentage differed between procedures. Needle fasciotomy had the lowest market share percentage approximately 7%. Collagenase injection had the highest average cost at US $4453.66 and was significantly higher than OF at US $3394.90 and NF at US $2010.75. Cost and distribution of procedures were further analyzed by geographic regions. In 2018, 32% of procedures performed were in the Northeastern US, 29% in the Midwestern US, 23% in the Southern US, and 16% in the Western US. Total number of Dupuytren procedures increased more than 300% in all regions across the US from 2015 to 2018. In every region, NF was the lowest cost intervention. Cost of OF and CI varied between regions and was often the most expensive intervention.

CONCLUSIONS

Treatment of DCs with NF seems to be the least costly treatment option. Needle fasciotomy seems to be the least commonly performed procedure. Regional data show variations in the cost of OF and CI. However, OF has the majority market share nationally and regionally. Although the cost of these procedures seems to vary regionally, the type of procedures being performed seem to be similar across regions.

Modified dynamic high-frequency ultrasound-guided needle aponeurotomy for Dupuytren's contracture

The aim of this report was to introduce the use of modified dynamic high-frequency ultrasound-guided needle aponeurotomy for Dupuytren's contracture. From January 2014 to February 2019, the technique was used in 42 consecutive patients who suffered from Dupuytren's contracture: 38 male and 4 female; mean age, 57 years (range, 32-80 years). Assessments comprised total active extension deficit and total active flexion of the fingers, active range of motion, Disabilities of the Arm, Shoulder and Hand (DASH) score, and EQ-5D index. Recurrence was defined as ≥20° flexion contracture. Compared to the opposite hand, preoperative total active extension deficit and total active flexion were 105° ± 32° and 221° ±  33°, respectively. The mean active range of motion of the metacarpophalangeal, proximal interphalangeal and distal interphalangeal joints was 42° ± 24°, 37° ± 26° and 62° ± 14°, respectively. Mean follow-up was 27 months (range, 24-35 months). There were no cases of tendon rupture or neurovascular injury. Total active extension deficit and total active flexion at the final follow-up were 17° ± 11° and 225° ± 32°, respectively. The mean active range of motion of metacarpophalangeal, proximal interphalangeal and distal interphalangeal joints was 73° ± 28°, 89° ± 24° and 63° ± 16°, respectively. The pre- and post-operative DASH scores were 18 ± 10 and 5 ± 2, respectively. Health-related quality of life on EQ-5D index improved from 0.72 ± 0.28 pre-operatively to 0.88 ± 0.72 post-operatively (p < 0.05). Recurrence rates in the metacarpophalangeal joint and proximal interphalangeal joint were 7% and 11%, respectively. The modified dynamic high-frequency ultrasound-guided needle aponeurotomy is a safe and effective way to treat Dupuytren's contractures. Ultrasound visualization ensures that the cords can be completely transected. Dynamic ultrasound decreases the risk of iatrogenic injury to the neurovascular bundles and tendons, and decreases the recurrence rate. LEVEL OF EVIDENCE: Therapeutic study, level IV.

Focused electromagnetic high-energetic extracorporeal shockwave (ESWT) reduces pain levels in the nodular state of Dupuytren's disease-a randomized controlled trial (DupuyShock)

Dupuytren’s disease is a progressive fibroproliferative disorder of the hand. In the nodular stage of Dupuytren’s disease, pain might limit daily hand activities and progress to finger contractures. Focused electromagnetic high-energetic extracorporeal shockwave therapy (ESWT) may reduce pain in Dupuytren’s nodules (Tubiana N). In this prospective, randomized, blinded, placebo-controlled single center trial, we enrolled 52 patients (mean age, 58.2 ± 9.2) with painful nodular Dupuytren disease Tubiana N. Randomization was done to either (group A) 3 treatments with focused electromagnetic high-energetic ESWT (2000 shots, 3 Hz, 0.35 mmJ/mm²/hand, Storz Duolith SD1, n = 27) or (group B) placebo ESWT (2000 shots, 3 Hz, 0.01 mJ/mm²/hand, n = 25) in a weekly interval. Primary outcome was the level of pain on a visual analogue scale (VAS 0–10) at 3/6/12/18 months, secondary outcomes were patient-related outcome measures (DASH score, MHQ score, URAM scale), grip strength, patient’s satisfaction, and Dupuytren’s disease progression over 18 months follow-up. Focused ESWT significantly improved outcomes. Pain was reduced from 3.6 ± 1.8 to 1.9 ± 1.2 at three, to 1.4 ± 0.7 at six, to 1.7 ± 1.6 after 12 months and 1.9 ± 0.8 after 18 months in the intervention group (47% reduction, p < 0.05). In the placebo group, pain on VAS increased from 2.2 ± 1.4 to 3.4 ± 1.7 at three, to 3.4 ± 1.8 at six, to 3.4 ± 1.4 at 12 and 3.1 ± 1.1 at 18 months (35% increase, p < 0.05). Quality-of-life score tended to improve in the intervention group (MHQ, 77 ± 19 to 83 ± 12; DASH, 12 ± 18 to 10 ± 9) while it deteriorated in the placebo group as Dupuytren’s disease was progressing (MHQ, 79 ± 15 to 73 ± 17; DASH, 6 ± 10 to 14 ± 13). The strength of the affected hand and fingers did not change significantly in either of the groups. Patients’ satisfaction was higher in the intervention group for symptom improvement (56% vs. 12%) and reduction of disease progression (59% vs. 24%). Any Dupuytren-related intervention was performed in 26% in the intervention group and in 36% in the placebo group within 18 months of follow-up (n.s.). Focused electromagnetic high-energetic ESWT can significantly reduce pain in painful nodules in Dupuytren’s disease in an 18-month perspective. (ClinicalTrials.gov Identifier: NCT01184586).

Healthcare Costs and Resource Use of Patients with Dupuytren Contracture Treated with Collagenase Clostridium Histolyticum or Fasciectomy: A Propensity Matching Analysis

Objective

Studies examining differences in US healthcare resource utilization (HCRU) and associated healthcare costs between collagenase clostridium histolyticum (CCH) and fasciectomy for Dupuytren contracture (DC) are limited. This study evaluated US HCRU and direct healthcare cost for the treatment of DC in privately insured patients using insurance claims.

Methods

This retrospective observational cohort study analyzed data from large nationwide insurance claims databases; it included individuals diagnosed with DC between July 1, 2011, and June 30, 2017, who were adults at index date (date of first treatment: CCH or fasciectomy). Participants had continuous health plan coverage 24 months pre-index and 12 months post-index date. All-cause and DC-related HCRU and healthcare costs from the payers’ perspective were compared between propensity score–matched cohorts. Generalized linear models assessed factors associated with all-cause total healthcare costs.

Results

Of 83,983 patients diagnosed with DC, 1932 adults receiving fasciectomy and 953 adults receiving CCH were included. The mean ± standard deviation total all-cause healthcare cost was significantly lower with CCH than with fasciectomy (US$11,897 ± US$14,633 versus US$15,528 ± US$22,254, respectively; P<0.001). After propensity score matching, 702 and 999 patients remained in the CCH and fasciectomy cohorts, respectively. In this analysis, all-cause and DC-related total costs were significantly lower in the CCH cohort versus the fasciectomy cohort (all-cause: US$11,044 ± US$12,856 versus US$12,912 ± US$19,237, respectively, P=0.02; DC-specific: US$3417 ± US$3671 versus US$5800 ± US$4985, P<0.001), mainly due to the lower frequency of outpatient visits. CCH treatment and the use of a consumer-driven healthcare plan were associated with lower healthcare costs.

Conclusion

Based on matched cohort data, adjusted 1-year healthcare costs for CCH-treated individuals were significantly lower compared with costs for fasciectomy-treated individuals.

Treatment of Dupuytren's disease using one full dose of Clostridiumhistolyticum collagenase at a lower concentration: Retrospective analysis of clinical outcomes

Clostridiumhistolyticum collagenase (CHC) is rapidly becoming a mainstream treatment option for Dupuytren's disease for hand surgeons. We performed a retrospective study of the efficacy of this substance at a lower concentration, but a higher total dose than recommended by the manufacturer. Thirty-nine patients with 43 affected hands were treated and analyzed at a mean follow-up of 27 months. Subgroup analysis was done for patients who received treatment in one or two joints (group A), and for patients who received treatment in more than two joints (group B). We found that our CHC solution is safe and effective when simultaneously treating as many as four joints affected by Dupuytren's disease. Patients in group B had a lower (but non-significant) treatment failure rate compared to patients in group A. Also, higher satisfaction rates were observed in group B, again non-significant. No major complications were observed in any group. CHC use is associated with only minor complications. The results are consistent even when up to four joints are treated with one dose. LEVEL OF EVIDENCE: III.

contribution of Australian research to Dupuytren’s disease

Introduction: While the history and epidemiology of Dupuytren's disease (DD) is well documented, its aetiology and risk factors, pathogenesis and treatment to this day are still being studied. This paper explores and summarises the significant contributions Australian researchers have made to the understanding of DD and its treatment methodologies.  Methods: We performed a systematic search on EMBASE from 1947 until March 2019 to identify all English literature using keywords: ‘Dupuytren/Dupuytrens/Dupuytren’s disease’ and ‘Australia/Australian/Australasian’. Relevant articles were also identified through bibliographic links. A separate search was conducted using Google Scholar, Research Gate and PubMed using the same keywords. In total, 40 articles were identified. A library search was also conducted, with one book identified with an Australian author. The Royal Australasian College of Surgeons Journal of Surgery was also analysed for published abstracts pertaining to DD from conference presentations between 2014 to 2019. Results and discussion: We present a narrative discussion of Australian research that has contributed to the understanding of DD from its aetiology to treatment methodologies.  Conclusion: Numerous Australians have made significant contributions to the understanding of DD, its pathogenesis, development and multiple treatment modalities, both non-surgical and surgical. Dupuytren’s disease is a progressive disease that reoccurs despite our best efforts and will continue to be a topic of focus for some time to come.

Collagenase injections for Dupuytren disease: 3-year treatment outcomes and predictors of recurrence in 89 hands

Background and purpose - Few prospective studies have reported the long-term effect durability of collagenase injections for Dupuytren disease. We assessed the 3-year treatment outcome of collagenase injections and predictors of recurrence.Patients and methods - We conducted a single-center prospective cohort study. Indication for collagenase injection was palpable Dupuytren's cord and active extension deficit (AED) ≥ 20° in the metacarpophalangeal (MCP) and/or proximal interphalangeal (PIP) joint. From November 2012 through June 2013, we treated 86 consecutive patients (92 hands, 126 fingers). A hand therapist measured joint contracture before, 5 weeks, and 3 years after injection. The patients rated their treatment satisfaction. Primary outcome was proportion of treated joints with ≥ 20° AED worsening between the 5-week and 3-year measurements. We analyzed predictors of recurrence.Results - 3-year outcomes were available for 83 of the 86 patients (89 hands, 120 treated fingers). Between the 5-week and 3-year measurements, AED worsened by ≥ 20° in 17 MCP (14%) and 28 PIP (23%) joints. At 3 years, complete correction (passive extension deficit 0-5°) was present in 73% of MCP and 35% of PIP joints. Treatment of small finger PIP joint contracture, greater pretreatment contracture severity, and previous fasciectomy on the treated finger were statistically significant predictors of recurrence. Treatment satisfaction was rated as very satisfied or satisfied in 59 of 87 hands. No long-term treatment-related adverse events were observed.Interpretation - 3 years after collagenase injections for Dupuytren disease, improvement was maintained and treatment satisfaction reported in two-thirds of the treated hands, with no adverse events. Complete contracture correction was achieved in 3 of 4 MCP joints, but in only a third of the PIP joints.

Using tongue depressors to aid cord localization during collagenase injection for Dupuytren disease

The aim of this paper was to introduce a simple and effective method to aid in isolation and stabilization of Dupuytren cords for collagenase injection. Tongue depressors were used to isolate and stabilize the cord during the injection procedure. The area to be injected was sterilely prepared. An assistant was then directed to place a tongue depressor on both sides of the cord. A total of 35 patients with Dupuytren disease were treated. Follow-up lasted two years. Post-operative Disabilities of the Arm, Shoulder and Hand (DASH) scores was 4±2. Health-related quality of life measured with the EQ-5D index was 0.89±0.4. Recurrence rates of metacarpophalangeal joint and proximal interphalangeal joint were 11% and 14% respectively, using a flexion contracture of 20° to define recurrence. Collagenase treatment using a modified injection method with the aid of tongue depressors are a safe, effective way to treat Dupuytren contractures of the fingers. The technique can isolate the cord, which improves visualization of the cord. It may allow improved accuracy with needle placement and helps to decrease the complications and recurrence.
