Risk factors of major complications after flap surgery in the treatment of stage III and IV pressure injury in people with spinal cord injury/disorder: a retrospective cohort study.

STUDY DESIGN: Retrospective cohort study. OBJECTIVES: To identify risk factors associated with major complications after flap surgery in people with spinal cord injury or disorder (SCI/D) and stage III and IV pressure injury (PI). SETTING: Swiss hospital specialized in the treatment of people with SCI/D using the Basel Decubitus Approach. METHODS: We examined 60 risk factors for major postoperative complications in PIs over sacrum/coccyx, ischium or trochanter between 01/2016 and 12/2021. We performed descriptive analysis and computed global p-values using likelihood ratio tests adjusted for clustering of PIs in individuals. RESULTS: We included 220 PI treatment procedure from 149 individuals. The study population consisted of 163 (74%) men, 133 (60%) traumatic SCI, 136 (58%) stage IV PI, 198 (90%) individuals with paraplegia, 93 (42%) with osteomyelitis, and 85 (39%) with recurrent PI. Major complications 42 (19%) occurred more often in individuals with stage IV PI (p < 0.01), individuals without osteomyelitis (p < 0.03), and individuals with pathological blood concentrations of cystatin c (p < 0.028), calcium (p < 0.048), and vitamin B12 (p < 0.0049) as well as normal blood concentrations of HbA1c (p < 0.033). Immobilization (p < 0.0089) and hospital stay (p < 0.0001) of individuals with major complications was longer. CONCLUSION: In the Basel Decubitus Approach, stage IV PI, absence of osteomyelitis, reduced vitamin B12 and calcium, elevated cystatin c, and normal HbA1c should be addressed to reduce major complications.

Effect of a computerized decision support system on the treatment approach of stage III or IV pressure injury in patients with spinal cord injury: a feasibility study.

BACKGROUND: Stage III and IV pressure injuries (PIs) in patients with spinal cord injury (SCI) require complex interdisciplinary and interprofessional treatment approaches that are difficult to implement. Practical aspects, such as information exchange and coordination, remain challenging. We investigated whether a computerized decision support system (CDSS) could increase treatment adherence and improve clinical outcomes and interprofessional collaboration. METHOD: In this feasibility study, a core team developed the initial treatment process and adapted it based on several discussions with clinical experts and information technologists. The CDSS followed the Basel Decubitus Approach and was used in a clinic specializing in SCI. Thirty patients with SCI admitted for stage III/IV PI between July 2016 and May 2017 were randomly allocated to standard or CDSS-supported care. Between-group differences in treatment adherence, complication rates, length of stay, and costs were analyzed using descriptive statistics. The use of the CDSS and potential barriers and facilitators were evaluated through interprofessional focus groups, transcribed verbatim, and thematically analyzed (30 participants). RESULTS: No differences in SCI characteristics, comorbidities, or PI characteristics (localization: ischium [number (n) = 19 PI, 63%], sacrum [n = 10 PI, 33%], recurrent PI [n = 21, 70%]) were found between the two groups. Furthermore, no statistically significant differences were observed in treatment adherence, frequency of major (20% vs. 13% between CDSS and control group) and minor (33% vs 27%) complications, and length of stay (98 [±28] vs 81 [±23] days). Healthcare professionals found the CDSS to be helpful for visualizing the treatment process. However, the high workload and difficulties in the information technology processes, such as missing reminders, slow computer performance and data processing, and poor accessibility, hindered the effective implementation of the CDSS. CONCLUSION: The implementation of the CDSS to support the treatment of stage III/IV PI in patients with SCI was feasible and included definitions of milestones, interventions, and outcomes. However, to assess the impact of the CDSS, a longer observation period is required. Further, the technical difficulties must be addressed, and solid integration of the CDSS into the clinical information system is necessary. TRIAL REGISTRATION: This quality improvement project received a declaration of no objection from the Ethics Committee of Northwest and Central Switzerland (EKNZ UBE-16/003), and ethical approval was received for the focus groups (EKNZ Req-2017-00860).

Treatment approaches of stage III and IV pressure injury in people with spinal cord injury: A scoping review.

CONTEXT: The treatment of pressure injury (PI) stage III and IV in people with spinal cord injury or spinal cord disorder (SCI/D) requires a multidisciplinary and surgical involvement. OBJECTIVES: This scoping review aims to identify published relevant surgical multidisciplinary treatment approaches, describe the elements and evaluate the effectiveness of the approaches. METHODS: We searched PubMed and Medline databases for studies about treatment approaches for people aged ≥18 years with chronic SCI/D and PI stage III or IV over ischium, trochanter or sacrum published between January 1990 and December 2021 in English or German language. Two independent reviewers screened the articles. One reviewer extracted information on study author(s), year of publication, study title, study design, country of origin, sample size as well as data on elements and effectiveness of the approaches. RESULTS: 10 different approaches were described in two retrospective cohort studies, three case series, five discussion papers, one review and one guideline. All approaches included debridement, flap surgery, pressure relief and immobilization as well as infection control. Some approaches described elements such as risk screening (7/10), osteomyelitis treatment (8/10), nutritional therapy (8/10), physiotherapy, occupational therapy and psychology (6/10), spasticity control (7/10), and prevention and education (6/10). Only one study reported on the effectiveness of the approaches. CONCLUSION: There are key elements for surgical multidisciplinary treatment approaches. However, due to differences in the content of some of these elements and missing elements in some approaches, comparability is difficult and the effectiveness of the complex approaches remains uncertain.

Osteomyelitis and antibiotic treatment in patients with grade IV pressure injury and spinal cord lesion-a retrospective cohort study.

STUDY DESIGN: Retrospective cohort study. OBJECTIVES: To analyze characteristics and treatment of osteomyelitis (OM) in the treatment of grade IV pressure injury (PI) in patients with spinal cord injury/disorder (SCI/D) following the Basel Decubitus Concept. SETTING: Acute care and rehabilitation clinic specialized in SCI/D. METHODS: Patients with SCI/D were admitted for grade IV PI treatment between 1st January 2010 and 28th February 2015. Patients, SCI/D, and PI characteristics were collected from chart reviews. Descriptive statistics and differences between groups with and without OM were evaluated. RESULTS: In total, 117 patients (87 male, 30 female) with 130 PI grade IV were included. In 95 patients (81%), OM was diagnosed histologically. In 87 cases, more than one bacterial species was involved. Out of 49 different bacterial species, Enterococcus faecalis and Staphylococus aureus were most frequently observed. Amoxicillin/clavulanic acid and ciprofloxacin were the most frequently used out of 24 different antibiotics. Length of antibiotic treatment varied between <8 days and >91 days with 31 patients receiving antibiotics for about 8 weeks. Complications occurred in all groups of antibiotic duration. Having a paraplegia, no OM and sacral PI was associated with increased complication rates, but the number of patients did not allow comprehensive risk factor analysis. CONCLUSION: Because the variety of patients concerning SCI/D, PI, and OM characteristics did not show a conclusive relation between length of antibiotic treatment and complication rates, the development of a subgroup specific treatment concept for PI in patients with SCI/D would be favorable to further optimize antibiotic treatment.
