Rates of surgical management of distal radius fractures are increasing internationally despite the higher cost and limited outcome evidence to support this shift. This study examines the epidemiology of distal radius fractures and asks if the same shift has occurred in Ontario, Canada (population 13.9 million).This population-based, retrospective cohort study examined distal radius fractures in people aged 18 years and older over a 10-year period (2004–2013). The incidence analyses were based on the first occurrence of a fracture within a 2-year time period. The number of fractures, age-adjusted incidence rates and frequency of fracture treatment type by year were assessed. We used a Poisson regression with robust standard errors to determine if there was a statistically significant change in the frequency of fracture treatment type over time.There were 25 355 distal radius fractures among Ontarians 18 years of age and older in 2013. Between 2004 and 2013, the age-adjusted incidence rate for people 35 years of age and older was stable, between 2.32 and 2.70 per 1000 population. Rates of cast immobilization remained stable between 82% and 84%. Of those patients treated surgically, the rate of open reduction and internal fixation rose from 7% in 2004 to 13% in 2013 at the expense of other types of surgical management.In Ontario, rates of cast immobilization are stable and there has been a movement toward open reduction and internal fixation among patients treated surgically.Le taux de prise en charge chirurgicale des fractures du radius distal augmente partout dans le monde, malgré le coût supérieur de l’intervention et le manque de données probantes sur les issues. Cette étude se penche sur l’épidémiologie des fractures du radius distal et cherche à savoir si cette augmentation se reflète en Ontario, au Canada (population : 13,9 millions).Cette étude de cohorte rétrospective basée sur la population examinait les fractures du radius distal chez les personnes âgées de 18 ans et plus sur une période de 10 ans (de 2004 à 2013). Les analyses de l’incidence étaient fondées sur la première occurrence de fracture en 2 ans. Le nombre de fractures, le taux d’incidence ajusté en fonction de l’âge et la fréquence annuelle des types de traitement des fractures ont été évalués. Nous avons utilisé une régression de Poisson avec des erreurs types robustes pour déterminer s’il y avait des changements statistiquement significatifs dans la fréquence des types de traitement des fractures au fil du temps.Il y a eu 25 355 fractures du radius distal chez les Ontariens de 18 ans et plus en 2013. Entre 2004 et 2013, le taux d’incidence ajusté en fonction de l’âge pour les personnes de 35 ans et plus était stable, entre 2,32 et 2,70 pour 1000 personnes. Le taux d’immobilisation plâtrée est demeuré stable entre 82 % et 84 %. Chez les patients traités par chirurgie, le taux de réduction chirurgicale et de fixation interne est passé de 7 % en 2004 à 13 % en 2013, au détriment des autres types de prise en charge chirurgicale.En Ontario, le taux d’immobilisation plâtrée est demeuré stable et il y a eu une augmentation de la réduction chirurgicale et de la fixation interne chez les patients traités par chirurgie.

In the age of information and patient-centered care, new methods of delivering postoperative care must be developed and evaluated.To determine whether follow-up care delivered via a mobile app can be used to avert in-person follow-up care visits compared with conventional, in-person follow-up care in the first 30 days following ambulatory surgery.A randomized clinical trial was conducted from February 1 to August 31, 2015, among ambulatory patients undergoing breast reconstruction at an academic ambulatory care hospital. Patients were randomly assigned to receive follow-up care via a mobile app or at an in-person visit during the first 30 days after the operation. Analysis was intention-to-treat.The primary end point was the number of in-person follow-up visits during the first 30 days after the operation. Secondary end points were the number of telephone calls and emails to health care professionals, patient-reported convenience and satisfaction scores, and rates of complications.Of the 65 women in the study (mean [SD] age, 47.7 [13.4] years), 32 (49%) were in the mobile app group, and 33 (51%) were in the in-person follow-up care group. Those in the mobile app group attended a mean of 0.66 in-person visits, vs 1.64 in-person visits in the in-person follow-up care group, for a difference of 0.40 times fewer in-person visits (95% CI, 0.24-0.66; P .001) and sent more emails to their health care professionals during the first 30 days after the operation (mean, 0.65 vs 0.15; incidence rate ratio, 4.13; 95% CI, 1.55-10.99; P = .005) than did patients in the in-person follow-up care group. This statistically significant difference was maintained at 3 months postoperatively. The mobile app group reported higher convenience scores than the in-person follow-up care group (incidence rate ratio, 1.39; 95% CI, 1.09-1.77; P = .008). There was no difference between groups in the number of telephone communications, satisfaction scores, or complication rates.Patients undergoing ambulatory breast reconstruction can use follow-up care via a mobile app to avert in-person follow-up visits during the first 30 days after the operation. Mobile app follow-up care affects neither complication rates nor patient-reported satisfaction scores, but it improves patient-reported convenience scores.clinicaltrials.gov Identifier: NCT02318953.

Background: Women’s College Hospital (WCH) offers specialized surgical procedures, including ambulatory breast reconstruction in post-mastectomy breast cancer patients. Most patients receiving ambulatory surgery have low rates of postoperative events necessitating clinic visits. Increasingly, mobile monitoring and follow-up care is used to overcome the distance patients must travel to receive specialized care at a reduced cost to society. WCH has completed a feasibility study using a mobile app (QoC Health Inc, Toronto) that suggests high patient satisfaction and adequate detection of postoperative complications. Objective: The proposed cost-effectiveness study models the replacement of conventional, in-person postoperative follow-up care with mobile app follow-up care following ambulatory breast reconstruction in post-mastectomy breast cancer patients. Methods: This is a societal perspective cost-effectiveness analysis, wherein all costs are assessed irrespective of the payer. The patient/caregiver, health care system, and externally borne costs are calculated within the first postoperative month based on cost information provided by WCH and QoC Health Inc. The effectiveness of telemedicine and conventional follow-up care is measured as successful surgical outcomes at 30-days postoperative, and is modeled based on previous clinical trials containing similar patient populations and surgical risks. Results: This costing assumes that 1000 patients are enrolled in bring-your-own-device (BYOD) mobile app follow-up per year and that 1.64 in-person follow-ups are attended in the conventional arm within the first month postoperatively. The total cost difference between mobile app and in-person follow-up care is $245 CAD ($223 USD based on the current exchange rate), with in-person follow-up being more expensive ($381 CAD) than mobile app follow-up care ($136 CAD). This takes into account the total of health care system, patient, and external borne costs. If we examine health care system costs alone, in-person follow-up is $38 CAD ($35 USD) more expensive than mobile app follow-up care over the first postoperative month. The baseline difference in effect is modeled to be zero based on clinical trials examining the effectiveness of telephone follow-up care in similar patient populations. An incremental cost-effectiveness ratio (ICER) is not reportable in this scenario. An incremental net benefit (INB) is reportable, and reflects merely the cost difference between the two interventions for any willingness-to-pay value (INB=$245 CAD). The cost-effectiveness of mobile app follow-up even holds in scenarios where all mobile patients attend one in-person follow-up. Conclusions: Mobile app follow-up care is suitably targeted to low-risk postoperative ambulatory patients. It can be cost-effective from a societal and health care system perspective.

ObjectiveThe primary aim of this study was to describe the prevalence of select oncogenic viruses within vulvar squamous cell carcinoma (VSCC) and their association with human immunodeficiency virus (HIV) status in women in Botswana, where the national HIV prevalence is the third highest in the world.MethodsA cross-sectional study of biopsy-confirmed VSCC specimens and corresponding clinical data was conducted in Gaborone, Botswana. Polymerase chain reaction (PCR) and immunohistochemistry (IHC) viral testing were done for Epstein-Barr virus, human papillomavirus (HPV) strains, and Kaposi sarcoma herpesvirus, and PCR viral testing alone was done for John Cunningham virus.ResultsHuman papillomavirus prevalence by PCR was 100% (35/35) among tested samples. Human papillomavirus type 16 was the most prevalent HPV strain (82.9% by PCR, 94.7% by either PCR or IHC). Kaposi sarcoma herpesvirus prevalence by PCR had a significant association with HIV status (P = 0.013), but not by IHC (P = 0.650).ConclusionsThe high burden of HPV, specifically HPV16, in vulvar squamous cell cancer in Botswana suggests a distinct HPV profile that differs from other studied populations, which provides increased motivation for HPV vaccination efforts. Oncogenic viruses Kaposi sarcoma herpesvirus and Epstein-Barr virus were also more prevalent in our study population, although their potential role in vulvar squamous cell cancer pathology is unclear.
