Development of a Multimodal, Personalized Intervention of Virtual Reality Integrated Within Physiotherapy for Patients With Complex Chronic Low-Back Pain

Background: Chronic low-back pain (CLBP) is the leading cause of years lived with disability. Physiotherapy is the most common treatment option for CLBP, but effects are often unsatisfactory. Virtual reality (VR) offers possibilities to enhance the effectiveness of physiotherapy treatment. Primary aim was to develop and test a personalized VR intervention integrated within a physiotherapy treatment for patients with CLBP.Methods: This study describes an intervention development process using mixed methods design that followed the Medical Research Council (MRC) framework. This involved a cocreation process with patients, physiotherapists, and researchers. A draft intervention was constructed based on a literature review and focus groups, and subsequently tested in a feasibility study and evaluated in focus groups. Focus group data were analyzed using thematic analysis. This intervention development process resulted in a final intervention.Results: Focus group data showed that VR and physiotherapy can strengthen each other when they are well integrated, and that VR needs to be administered under the right conditions including flawless technology, physiotherapists with sufficient affinity and training, and the right expectations from patients. The draft intervention was considered feasible after evaluation by four patients and three physiotherapists and was further complemented by expanding the training for physiotherapists and improving the protocols for physiotherapists and patients. The final intervention consisted of a 12-week physiotherapy treatment with three integrated VR modules: pain education, physical exercise, and relaxation.Conclusion: Using the MRC framework in cocreation with the end users, a personalized VR intervention integrated within a physiotherapy treatment for patients with CLBP was developed. This intervention was found to be feasible and will subsequently be evaluated for (cost-)effectiveness in a cluster randomized controlled trial

Epidemiology of Limb Amputations and Prosthetic Use During COVID-19 Pandemic in the Netherlands

Objective: To evaluate the trends in the incidence of major limb amputations and the prevalence of Dutch prosthetic users at the national level in The Netherlands between 2012 and 2021 (during the COVID-19 pandemic). Local hospitals in The Netherlands reported a doubling of major lower limb amputations during COVID-19, information about a change in the incidence of major upper limb amputations was not reported. We could not confirm this remarkable increase in major lower limb amputations in our institution, nor did we observe a change in the incidence of major upper limb amputations. We hypothesize that the COVID-19 pandemic had no effect on the number of major limb amputations. Design: Observational retrospective study analyzing national open-access databases of health insurance claims. Setting: The Dutch national opensource database www.opendisdata.nl was used to retrieve the incidence of limb amputations in the period 2012-2021, stratified by the level of amputation and the cause of amputation. The results were verified using the www.gipdatabank.nl databank. This period included 4 intervals of nationwide COVID-19 lockdowns. Participants: 60,848 patients who underwent limb amputations at the upper or lower extremity in the Netherlands from 2012 to 2021 (N=60,848) were included in this study. Intervention: Not applicable. Main Outcome Measures: Upper- and lower-limb amputation and prosthetic use. Results: Data were retrieved for a total of 60,848 patients in the Netherlands, who underwent 68,180 amputations of the upper and lower extremities at any level from 2012 to 2021, including 22,095 major amputations of the lower extremities. The ongoing trend of stable numbers of major lower-limb amputations from 2012 to 2019 continued in 2020 and 2021. The verification of these data at the level of prosthetic users confirmed that the annual trends were unchanged. Conclusion: The reported increased numbers of major lower-limb amputations during the COVID-19 pandemic in the Netherlands could not be confirmed using nationwide epidemiologic data

Risk Factors for Adhesion-Related Readmission and Abdominal Reoperation after Gynecological Surgery: A Nationwide Cohort Study

More than half of women in developed countries undergo surgery during their lifetime, putting them at risk of adhesion-related complications. Adhesion-related complications include small bowel obstruction, chronic (pelvic) pain, subfertility, and complications associated with adhesiolysis during reoperation. The aim of this study is to predict the risk for adhesion-related readmission and reoperation after gynecological surgery. A Scottish nationwide retrospective cohort study was conducted including all women undergoing a gynecological procedure as their initial abdominal or pelvic operation between 1 June 2009 and 30 June 2011, with a five-year follow-up. Prediction models for two- and five-year risk of adhesion-related readmission and reoperation were constructed and visualized using nomograms. To evaluate the reliability of the created prediction model, internal cross-validation was performed using bootstrap methods. During the study period, 18,452 women were operated on, and 2719 (14.7%) of them were readmitted for reasons possibly related to adhesions. A total of 2679 (14.5%) women underwent reoperation. Risk factors for adhesion-related readmission were younger age, malignancy as indication, intra-abdominal infection, previous radiotherapy, application of a mesh, and concomitant inflammatory bowel disease. Transvaginal surgery was associated with a lower risk of adhesion-related complications as compared to laparoscopic or open surgeries. The prediction model for both readmissions and reoperations had moderate predictive reliability (c-statistics 0.711 and 0.651). This study identified risk factors for adhesion-related morbidity. The constructed prediction models can guide the targeted use of adhesion prevention methods and preoperative patient information in decision-making
