Cost comparison of pressure ulcer preventive dressings: hydrocolloid dressing versus transparent polyurethane film.

OBJECTIVE: To evaluate and compare the costs of using a transparent polyurethane film (PF) and hydrocolloid dressing (HD) in the prevention of pressure ulcers (PUs). METHOD: This descriptive, observational, longitudinal, comparative study was conducted in the intensive care units, coronary care unit and medical clinic of a charity hospital in Brazil. Data were collected during a 30-day study period, consisting of physical examination, assessment of risk factors for PU development and application of the Braden scale, which were performed at inclusion in the study and once daily during hospitalisation. Either PF or HD was applied bilaterally in the sacral and trochanteric regions for prevention of PUs in patients at a moderate to high risk of PUs according to the Braden scale, and costs of using PU preventive dressings were estimated. RESULTS: The mean total costs per dressing change per patient when using the HD and PF to prevent PUs were 413.60 BRL and 74.04 BRL, respectively. There were significant between-group differences in mean costs for all variables, except for saline solution and nurse-technician services. CONCLUSION: Results showed that the mean cost per dressing change per patient was lower when using the transparent PF than when using the HD.

Impact of surgical wound dehiscence on health-related quality of life and mental health.

OBJECTIVE: To assess the impact of surgical wound dehiscence on health-related quality of life and mental health. Dehiscence of surgical wounds is a serious postoperative complication associated with high morbidity and mortality. METHOD: Sixty-one adult patients, who had undergone neurological, general, colorectal, orthopaedic, gynaecological, plastic, cardiovascular, urological or neurological surgery in a university hospital in Brazil, were assessed between 30 and 180 days after surgery. Twenty participants who achieved complete wound healing were allocated to the control group and 41 participants who developed surgical wound dehiscence were allocated to the dehiscence group. Patients unable to complete the questionnaires because of cognitive impairment and those who declined to participate or died were excluded from the study. Data were collected using a questionnaire assessing sociodemographic and clinical characteristics of participants; the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36); and the Beck Depression Inventory (BDI). RESULTS: Surgical wound dehiscences were 0.5-30 cm in length, 0.5-7 cm in depth, and located in the arms, legs or trunk. There were significant between-group differences in mean scores on the physical functioning (p<0.01), role physical (p<0.01), social functioning (p=0.01), and bodily pain (p=0.01) dimensions of the SF-36. Participants with wound dehiscence reported significantly higher BDI scores (more depressive symptoms) than controls (p=0.01). CONCLUSION: Surgical wound dehiscence had a negative impact on the physical functioning, role physical, social functioning, and bodily pain dimensions of health-related quality of life and on mental health.

Using transparent polyurethane film and hydrocolloid dressings to prevent pressure ulcers.

OBJECTIVE: To compare the performance and effectiveness of a hydrocolloid dressing (HD) and a transparent polyurethane film (PF) in preventing pressure ulcer (PU) development. METHOD: The study was conducted in the intensive care unit, coronary care unit and medical clinic of the Holy House of Mercy of Passos, Brazil. Data were collected 48 hours after admission and during hospitalisation. The Braden scale was used for PU risk assessment. Consecutive eligible patients without PUs were randomly assigned by lottery to the two groups, either the HD or PF group. RESULTS: Of the 160 eligible patients, significant between-group differences were found in the mean total number of dressing changes (HD, 6.09±1.655 changes; PF, 5.59±2.036 changes; p=0.010), and mean number of dressing changes in the sacral region (HD, 2.50±0.871; PF, 2.05±0.825; p=0.001), with the PF group requiring significantly fewer changes than the HD group. The most common reasons for changing dressings in both groups were moisture (PF 51.1%; HD 47.9%) and shear (HD 43%; PF 38.9%), with a significant difference in shear between groups. The incidence of PUs was significantly lower (p=0.038) in the PF group (8.7%) compared with that in the HD group (15%). CONCLUSION: The results suggest that the transparent polyurethane film had a better performance and was more effective than the hydrocolloid dressing in preventing PU development.

Impact of compression therapy using Unna's boot on the self-esteem of patients with venous leg ulcers.

OBJECTIVE: To assess self-esteem in patients with venous leg ulcers treated with Unna's boot. • METHOD: A descriptive, analytic, clinical study was conducted from June 2010 to May 2011 in an outpatient wound care clinic in São Paulo, Brazil. Patients of both sexes, aged ≥18 years, who had had a venous leg ulcer for more than one year and a Doppler ankle brachial index ranging from 0.8-1.0 were consecutively selected for inclusion. Patients were treated with wound dressings and Unna's boot. Self-esteem was assessed using the Brazilian version of the Rosenberg Self-Esteem Scale (RSE) at inclusion (baseline) and after 4, 8, and 12 months of compression therapy using Unna's boot. The scale is reverse-scored; thus lower scores indicate higher levels of self-esteem. • RESULTS: The patients showed a slight but significant improvement in self-esteem after 4 months of treatment (mean RSE score=17.12) compared with baseline (mean RSE score=24.90). However, a marked and significant improvement in self-esteem was observed after 8 months (mean RSE score=7.40) and 12 months (mean RSE score=2.10) of compression therapy using Unna's boot. • CONCLUSION: Patients with venous leg ulcers treated with Unna's boot for 12 months showed a significant improvement in self-esteem • DECLARATION OF INTEREST: All authors declare that no competing financial interests exist. There was no external funding for this study.

Quality of life and self-esteem in patients with paraplegia and pressure ulcers: a controlled cross-sectional study.

OBJECTIVE: To evaluate health-related quality of life (HRQoL) and self-esteem in patients with traumatic spinal cord injury (SCI) and pressure ulcers. METHOD: This study was a controlled cross-sectional study. HRQoL was assessed using the generic Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) questionnaire and the Rosenberg Self-Esteem/UNIFESP-EPM Scale. A total of 120 patients with traumatic SCI were included in the sample, of which 60 had pressure ulcers and were assigned to the study group, and 60 had no pressure ulcers and were assigned to the control group. Statistical analysis was performed using the chi-square test, Fisher's exact test, and Student's t-test. RESULTS: Of the 60 patients in the study group, 83.3% were men and the mean age was 38.17 years (SD = 9.08 years). When compared with controls, patients in the study group reported significantly lower scores (worse health status) on all SF-36 subscales (p less than or equal to 0.0013) except for general health (p=0.109). The RSE/UNIFESP-EMP scale total score indicated that patients with pressure ulcers had significantly lower self-esteem than controls (p<0.001). CONCLUSION: Pressure ulcers had an adverse impact on the HRQoL and self-esteem of patients with SCI. DECLARATION OF INTEREST: There were no external sources of funding for this study. The authors have no conflicts of interest to declare.

Feelings of powerlessness in patients with venous leg ulcers.

OBJECTIVE: To assess feelings of powerlessness in patients with venous leg ulcers. METHOD: An exploratory, descriptive, analytic, cross-sectional study was conducted at the Plastic Surgery Outpatient Clinic of the São Paulo Hospital (HSP) and at the Outpatient Wound-Care Clinic of the Sorocaba Hospital Complex (CHS), Brazil, from May 2010 to April 2012. Sixty patients with venous leg ulcers (VLUs), of both sexes, aged greater than or equal to 18 years, from the two outpatient wound-care clinics were selected to participate in the study. All participants responded to the Powerlessness Assessment Tool (PAT) for adult patients. Statistical analysis was performed using the Chi-square test, Mann-Whitney U test and Kruskal-Wallis test at a significance level of 5% (p<0.05). RESULTS: Forty-four (73%) patients were women and 38 (63%) were aged 61-70 years. Eight (13%) patients were alcoholics and 46 (77%) were smokers. Thirty-two (53%) patients had a VLU for more than 10 years; the ulcer area ranged from 11-20 cm2 in 19 (32%) patients and was >30 cm2 in 18 (30%) patients. Mean total PAT score was 47.83 ± 7.99 and ranged from 51-60 for 31 (52%) patients and from 41-50 for 19 (32%) patients. CONCLUSION: Most patients with venous leg ulcers reported high PAT scores, revealing the presence of strong feelings of powerlessness. DECLARATION OF INTEREST: The authors have no conflicts of interest to declare.

The impact of compression therapy with Unna's boot on the functional status of VLU patients.

OBJECTIVE: To assess disability in patients with venous leg ulcers treated with compression therapy with Unna's boot. METHOD: A descriptive analytic case control study was conducted from June 2010 to May 2011 in an outpatient wound care clinic in interior Brazil. Fifty patients of both sexes, aged 18 years or above, who had had a venous leg ulcer for more than 1 year and a Doppler ankle-brachial index of 0.8-1.0 were selected for the study. Patients were treated with wound dressings and Unna's boot. Disability was assessed using the 20-item Stanford Health Assessment Disability Scale (HAQ-20). Statistical analysis was performed using the Student's t-test, the Kruskal-Wallis test and the chi-square test of independence, all at a significance level of 0.05 (p < 0.05). RESULTS: The mean overall HAQ score at inclusion (baseline) was 2.98, indicating impaired functional capacity. After 8 and 12 months of compression treatment with Unna's boot, the mean overall HAQ scores were 1.35 and 1.0, respectively, indicating good functional capacity. CONCLUSION: Patients with venous leg ulcer reported severe difficulty or serious disability in their daily functioning at baseline; after 8 months of treatment with Unna's boot, these patients were able to perform activities of daily living.

Feelings of powerlessness and hope for cure in patients with chronic lower-limb ulcers.

OBJECTIVE: To assess feelings of powerlessness and hope for cure in patients with chronic venous leg ulcers (VLUs) and diabetic foot ulcers (DFUs). METHOD: A clinical, analytical, descriptive study was conducted from April to September 2012 in a wound-care clinic in Brazil, on consecutive patients presenting withVLUs and DFUs. The Powerlessness AssessmentTool for Adult Patients (PAT) and the Herth Hope Index (HHI) were used.Total PAT scores range 12-60 and the higher the score, the stronger the feelings of powerlessness. The HHI ranges 12-48, with higher scores indicating higher levels of hope RESULTS: In total, 80 consecutive patients were recruited (40 VLU and 40 DFU). Mean PAT score was 53.3 +/- 9.6 (range 21-60) for DFU patients and 34.3 +/- 7.7 (range 21-60; p = 0.001) forVLU patients, suggesting these individuals had strong feelings of powerlessness. The mean HHI was 16.5 +/- 16.5 (range 12-40) for DFU patients and 27.5 +/- 27.5 (range 12-40; p = 0.001) for patients with VLUs, indicating low levels of hope. CONCLUSION: The results suggest that patients with DFUs had stronger feelings of powerlessness regarding their condition and less hope of recovery compared with patients with VLUs.

Spirituality and subjective wellbeing in patients with lower-limb ulceration.

OBJECTIVE: To assess subjective wellbeing and spirituality in patients with either venous leg ulcers (VLUs) or diabetic foot ulcers (DFUs). METHOD: This was a prospective, descriptive, analytical study conducted from December 2011 to October 2012. The study was approved by the Institutional Research Ethics Committee. A convenience, non-probability sample of 80 patients with either VLUs (n=40) or DFUs (n=40) were consecutively selected from an outpatient clinic of a university hospital in the city of Pouso Alegre, Brazil. Most participants were practising Catholics. The Subjective Wellbeing Scale and Spirituality Self-Rating Scale were administered to all participants. RESULTS: Thirty-two (80%) patients with foot ulcers and 22 (55%) patients with leg ulcers reported going to church sometimes or rarely. Most participants regarded religiosity and spirituality as synonymous, and living with the ulcers was seen as a punishment. The mean scores on the positive affect, negative affect, and life satisfaction components of the Subjective Wellbeing Scale were 2.48, 1.57 and 1.88, respectively, for patients with DFUs, and 2.55, 1.55 and 1.50, respectively, for patients with VLUs, with significant difference in life satisfaction between groups (p=0.003). The mean score on the Spirituality Self-Rating Scale was 11.40 for patients with VLUs and 12.85 for those with DFUs, showing that the participants had low levels of spirituality. CONCLUSION: VLUs and DFUs had a negative impact on subjective wellbeing and spirituality, but patients with DFUs showed poorer subjective wellbeing and spirituality than those with VLUs.
