  Background: Wells score comprises subjective elements, making physicians reluctant to use Wells score or cause them to use it incorrectly. Objectives: To develop and internally validate a prediction score that is objective and simple for evaluating suspected deep vein thrombosis (DVT), with a safety comparable with that of Wells score. Methods: We performed a post hoc analysis using data from the Ri-Schedule study (NCT02486445) involving suspected DVT patients at Østfold Hospital’s Emergency Department, Norway (2015-2018). Candidate variables were identified through bootstrapping technique, with a confirmed DVT diagnosis as the outcome variable. Sensitivity, specificity, negative predictive value (NPV), and positive predictive values (PPV) were estimated and compared with the 2-tier Wells score. Results: Among 1312 patients (median age, 64 years [IQR, 52-73]; 55% women), 19.9% were diagnosed with DVT. Exploration of 30 variables identified tenderness along deep veins and previous venous thromboembolism as significant predictors (selection frequency >60% in 1000 bootstrapping samples). The derived score categorized 450 patients with 0 items as unlikely to have DVT, of whom 8.0% were diagnosed with DVT, compared with 8.2% in DVT unlikely category according to Wells score. Compared with Wells score, the derived score demonstrated sensitivity of 86.2 (95% CI, 81.4-90.2) vs 80.1 (95% CI, 74.7-84.8), specificity of 39.4 (95% CI, 36.4-42.4) vs 55.3 (95% CI, 52.2-58.3), NPV of 92.0 (95% CI, 89.4-94.0) vs 91.8 (95% CI, 89.7-93.5), and PPV of 26.1 (95% CI, 24.8-27.5) vs 30.8 (95% CI, 28.9-32.8). When incorporating D-dimer cutoff of <0.5 mg/mL, the derived score had sensitivity of 99.6 (95% CI, 97.9-99.9), specificity of 16.1 (95% CI, 13.1-18.4), NPV of 99.4 (95% CI, 96.0-99.9), and PPV of 22.8 (95% CI, 22.3-23.3). Conclusion: The derived DVT score, with 2 objective variables, had a comparable safety with that of the Wells score. However, an external validation is mandated prior to clinical use.

  Aim: The aim of this study was to explore patients' experiences after gynaecological day surgery one and 30 days postoperatively, as well as potential factors influencing these experiences. Design: The study had a multicentre, quantitative, longitudinal design. Methods: The study was conducted in three different hospitals' day surgical unit and included patients undergoing gynaecological surgery in general anaesthesia. We used a questionnaire including the European Quality of Life tool (EQ5D3L), the Quality-of-Recovery-15 questionnaire (QoR-15) and items relating to patient experiences, the first day (T1, n = 444) and 30 days (T2, n = 193) after surgery. Data were collected in the period March 2019 to March 2020. Results: Results show that patients mainly had positive experiences and ranged quality of recovery high, even though some areas needed improvement. Patient scores on the QoR-15 relating to their experiences 24 h postoperative were rated higher at T1 than at T2. Twenty per cent of the respondents experienced complications such as infection, haemorrhage and pain. About 1/5 of these contacted healthcare services, and three per cent was hospitalized. EQ5D score was the only factor that made an statistically significant impact on patients' experiences with quality of recovery (R2 .169, F = 82.87). However, this effect was weak.

  Bakgrunn: Operasjonssykepleiefaget består av flere kunnskapsdimensjoner og litteraturgjennomgang viser at den komplekse kompetansen er lite identifisert og beskrevet. Hensikt: Hensikten med denne studien var å undersøke operasjonssykepleiernes opplevde kompetanse i forhold til arbeidskrav de møter og sett i forhold til spesifikke kompetanseområder. Metode: En kvantitativ tverrsnittstudie med et spørreskjema ble anvendt til å kartlegge opplevd kompetanse, i perioden våren 2012. Antall respondenter var 30. Databearbeidingen er framstilt med deskriptiv statistikk. Resultat: Operasjonssykepleierne opplevde godt samsvar mellom opplevd kompetanse og avdelingens arbeidskrav, høyest innenfor teknisk kompetanse, lavest innenfor pårørendekompetanse. Best gjennomsnittlig skår fikk de med 10–14 års erfaring. Konklusjon: Resultatet viste at operasjonssykepleierne i stor grad opplevde å ha en tilfredsstillende kompetanse i forhold til arbeidskrav. Studien kan bidra til å fokusere på viktige spørsmål knyttet til kompetanseutvikling, også innenfor ikke-tekniske kompetanseområder. Dette kan gi avdelingen data som kan være med i planleggingen av kompetanseprogram både for den enkelte utøver og for avdelingen som helhet.
