Global patient outcomes after elective surgery: prospective cohort study in 27 low-, middle- and high-income countries.

BACKGROUND: As global initiatives increase patient access to surgical treatments, there remains a need to understand the adverse effects of surgery and define appropriate levels of perioperative care. METHODS: We designed a prospective international 7-day cohort study of outcomes following elective adult inpatient surgery in 27 countries. The primary outcome was in-hospital complications. Secondary outcomes were death following a complication (failure to rescue) and death in hospital. Process measures were admission to critical care immediately after surgery or to treat a complication and duration of hospital stay. A single definition of critical care was used for all countries. RESULTS: A total of 474 hospitals in 19 high-, 7 middle- and 1 low-income country were included in the primary analysis. Data included 44 814 patients with a median hospital stay of 4 (range 2-7) days. A total of 7508 patients (16.8%) developed one or more postoperative complication and 207 died (0.5%). The overall mortality among patients who developed complications was 2.8%. Mortality following complications ranged from 2.4% for pulmonary embolism to 43.9% for cardiac arrest. A total of 4360 (9.7%) patients were admitted to a critical care unit as routine immediately after surgery, of whom 2198 (50.4%) developed a complication, with 105 (2.4%) deaths. A total of 1233 patients (16.4%) were admitted to a critical care unit to treat complications, with 119 (9.7%) deaths. Despite lower baseline risk, outcomes were similar in low- and middle-income compared with high-income countries. CONCLUSIONS: Poor patient outcomes are common after inpatient surgery. Global initiatives to increase access to surgical treatments should also address the need for safe perioperative care. STUDY REGISTRATION: ISRCTN5181700

CONTRAST : gamification of arm-hand training for stroke survivors

This paper describes the design of a serious game that supports arm-hand training for stroke survivors aiming to render rehabilitation training enjoyable and sustainable. The design of this game was based on combining well-known game-design principles and principles of task-oriented training. Most importantly the game involves the manipulation of every day physical objects and the game's difficulty is dynamically adapted to the patient's performance. The game was evaluated in actual training with two stroke patients for a period of a week. Their feedback shows the promise of this approach; the study motivates the further development of game content and further extension of adaptability features

Prevalence of vertebral deformities and symptomatic vertebral fractures in corticosteroid treated patients with rheumatoid arthritis

Objective. This study was designed to determine whether the prevalence of vertebral deformities in patients with rheumatoid arthritis (RA) treated with corticosteroids (Cs) is higher than in RA patients not receiving Cs therapy. Patients and methods. This multicentre cross-sectional study included 205 patients with RA who were receiving Cs orally on a daily basis and 205 patients with RA who did not receive Cs, matched for sex and age. Vertebral deformities were scored according to the Kleerekoper method. Results. Vertebral deformities were found in 52 (25%) patients on Cs and in 26 (13%) patients not on Cs. Sixteen (8%) patients in the group on Cs had experienced clinical manifestations of an acute vertebral fracture in the past vs only three patients (1.5%) among those not on Cs. The use of Cs tended to increase the risk of developing a vertebral deformity [adjusted odds ratio (OR) 1.56, 95% confidence interval (CI) 0.81-2.99] and symptomatic vertebral fracture (adjusted OR 1.42, 95% CI 0.24-8.32). Each 1-mg increase in the current daily Cs dose increased the risk of a vertebral deformity (adjusted OR 1.05, 95% CI 0.98-1.13) and of a symptomatic vertebral fracture (adjusted OR 1.05, 95% CI 0.89-1.24). Conclusion. There is a higher prevalence of vertebral deformities and clinical manifestations of vertebral fractures in patients on Cs than in those not on Cs. Our data indicate that the use of Cs and each 1-mg increase in the current daily Cs dose may increase the risk of development of a vertebral deformity and symptomatic vertebral fracture in patients with RA
