Objective: In previous studies, venous ulcers (VUs) have been found to occur more often in patients with lower socioeconomic status. The aim of this study was to explore if socioeconomic factors influence the delay of referral to a vascular service or the time to healing after superficial venous intervention.

Method: In this prospective study, patients answered a questionnaire about the duration and recurrence of their VU, comorbidities, body mass index (BMI), smoking, alcohol, social and physical activities, ambulatory status, education, marital status, housing, perceived economic status and dependence on home care. Postoperative complications, VU healing and recurrence were noted one year after superficial venous intervention.

Results: A total of 63 patients were included in this study (30 females and 33 males), with a mean age of 71.2 years (range: 37-92 years). Duration of the present VU in patients was: <3 months in 48%; 3-6 months in 27%; 6-12 months in 11%; and >12 months in 14%. Risk factors for delayed referral were recurrent VU (odds ratio (OR): 4.92; p=0.021); walking impairment (OR: 5.43; p=0.009) and dependence on home care (OR: 4.89: p=0.039) in a univariable analysis. The latter was the only significant finding in a multivariable analysis with socioeconomic risk factor (OR: 4.89; p=0.035). In 85% of patients, their VU healed without recurrence during one year follow-up. Healing took longer if the patients: were of older age (p=0.033); had a normal BMI (independent samples t-test, p=0.028); had a recurrent VU (OR: 5.00; p=0.049); or walking impairment (Fishers exact test, OR: 9.14; p=0.008), but no significant socioeconomic risk factors were found.

Conclusion: In this study, socioeconomic factors were not important risk factors for delayed referral of VU patients to a vascular service or prolonged healing time after superficial venous intervention.

Objective: The presence of peripheral artery disease (PAD) in patients with diabetic foot ulcers (DFUs) is a significant risk factor for chronicity and amputation. Ankle-brachial pressure index (ABPI) is a screening tool for PAD. Brachial systolic pressure measurement, used as a denominator in the calculation of ABPI, produces inaccurate results in patients with obesity and the presence of heavy clothing. The wrist, however, is easily accessible, and the ankle-wrist pressure index (AWPI), if comparable with ABPI, may be useful in screening selected patients. This study aimed to assess the efficacy of AWPI in diagnosing perfusion in DFUs and compare it to ABPI in patients with DFUs.

Method: ABPI and AWPI were calculated by measuring systolic blood pressure in the arteries of the ankle, arm and wrist with a handheld Doppler. Actual perfusion was determined by the presence or absence of PAD by duplex ultrasound.

Results: A total of 46 lower extremities in 41 patients were studied. The prevalence of PAD was 61%. Duplex ultrasound confirmed that the sensitivity of ABPI and AWPI in detecting PAD in patients with DFUs was 67.9% and 71.4% respectively, whereas the specificity of ABPI and AWPI was 94.4% and 88.9% respectively. On receiver operating characteristic analysis, the area under the curve of ABPI and AWPI was 0.804 and 0.795, respectively. A statistically significant positive correlation between ABPI and AWPI was found (r=0.986; p<0.001).

Conclusion: There was a good correlation between ABPI and AWPI over a wide range of values. ABPI and AWPI may have a similar role in predicting perfusion in patients with DFUs. AWPI could be used in place of ABPI in selected patients in whom measuring ABPI may be difficult.

Objective: To evaluate the use and performance of a gelling fibre dressing (Biatain Fiber; Coloplast A/S, Denmark) in the management of wounds in community nursing practice.

Method: A sub-analysis of the prospective, observational, real-world VIPES (Observatoire en Ville des Plaies ExSudatives) study was conducted. Patients with exuding wounds, for which nurses chose to apply the gelling fibre as a primary dressing, were included. Outcomes included assessments of wound condition and patient/nurse opinion.

Results: Overall, 149 patients with acute (n=52; 34.9%) or hard-to-heal (chronic) (n=97; 65.1%) wounds were included. At baseline, mean±standard deviation wound age was 351.5±998.2 days, 108 (72.5%) wounds were moderately-to-highly exuding, and 126 (84.6%) showed exudate pooling in the wound bed. At the last follow-up visit, 29 (19.5%) wounds had healed, within a median of 36 days, and 64 (43.0%) were progressing towards healing. From baseline to the last follow-up visit, significant reductions in wound surface area (p<0.05), depth (p<0.01), exudate level (p<0.0001), and in the proportion of wounds with sloughy tissue (p<0.0001) were observed. Most wounds had no (n=86; 58.5% (two missing values)) or low exudate pooling (n=45; 30.6% (two missing values)) at the last visit and proportions of patients with healthy wound edges/periwound skin increased from baseline. At the last visit, wounds were considered improved by nurses in 71.4% (n=105) of cases, and by patients in 66.7% (n=98) of cases (two patients missing).

Conclusion: Patients who received treatment with the gelling fibre experienced improvements in the condition of a range of complex wounds. This analysis highlights the importance of adequate exudate management, and indicates how the selection of an appropriate wound dressing can encourage healing progression.

Objective: A hard-to-heal wound is defined as a wound that failed to proceed through the normal phases of wound healing in an orderly and timely manner. The purpose of this article is to describe the impact of hard-to-heal wounds on the wellbeing, quality of life (QoL) and satisfaction with QoL of patients in Oman with hard-to-heal wounds.

Method: A descriptive cross-sectional study of patients with hard-to-heal wounds attending three tertiary care hospitals using a self-reported questionnaire was conducted.

Results: A total of 275 patients took part in the study. Patients reported a low wellbeing score (67.06±19.72), moderate QoL score (52.18±25.07) and moderate satisfaction scores (68.91±23.88). Significant mean differences were reported with age, sex, educational level, monthly income and type of wound all at p<0.05.

Conclusion: The findings of this study demonstrated that hard-to-heal wounds could influence the wellbeing, QoL and overall satisfaction with QoL of patients.

Objective: Multiple techniques are available for closing skin defects, such as skin grafts, flaps and tissue expansion. The tissue extender MID SEW (MID, France) was developed to achieve dermatotraction or suture reinforcement. The aim of this study was to evaluate the effectiveness and safety of this innovative silicone extender for large surgical wounds.

Method: A single-centre retrospective and observational study on an unselected consecutive cohort of patients treated with a tissue extender was conducted. Indications, initial and final wound surfaces, and adverse events (AEs) were retrieved from electronic medical records. The main outcome measure was the time to complete wound closure.

Results: We identified 50 patients from July 2017 to December 2018. Patients underwent cutaneous tumour-wide excision (n=44), or pilonidal disease surgical treatment (n=6). The average initial wound area was 53.3±42.4cm². Healing was complete, without secondary dehiscence, within the first seven days after device withdrawal for 41 patients (82%). At least one AE was experienced by eight patients (16%) during the study period: five inflammation; five wound dehiscence; two skin necrosis; and one pain.

Conclusion: This case series suggests that the tissue extender may be effective and safe in its dermatotraction and suture reinforcement indications in the treatment of large wounds after wide excision of skin cancer or treatment of pilonidal disease.

Objective: The objective of this study was to evaluate whether a systematic image assessment protocol using SPY Elite images (LifeCell Corp., US) of viable tissue at the periphery of the surgical field was associated with positive wound healing outcomes following mastectomy and breast reconstruction.

Method: Patients undergoing mastectomy and subsequent breast reconstruction surgery at a single tertiary medical centre were included. SPY images were prospectively analysed using a systematic image assessment protocol, and an absolute value of mean fluorescence was calculated by measuring peripheral, in-situ tissue from each image. Patient medical records were retrospectively reviewed for demographics, surgical characteristics and postoperative outcomes. These variables were statistically tested for associations with mean fluorescence.

Results: A total of 63 patients were included in the final analysis. We found that objectively determined mean fluorescence values were not statistically significantly associated with postoperative complications.

Conclusion: In this study, objectively measured mean fluorescence values representing breast tissue remaining after dissection showed little utility in the assessment of postoperative wound healing outcomes as they did not identify patients who would later have complications of wound healing.
