    Studies in Health Technology and Informatics
    Patient experience (PX) is an important evaluation criterion for quality in healthcare. Compared to patient satisfaction, however less research has focused on the development of instruments to measure experiences of patients and their families. In the article, we describe the process of developing a PX questionnaire for the parents of pediatric patients in the context of children's hospital and illustrate the questionnaire items for measuring PX. The phases of the development process included retrospective interviews, description of the themes influencing PX and the metrics for measuring PX, as well as iterative development of three versions of questionnaires including data gathering and factor analysis. The final versions of the surveys suggested for implementation at the hospitals include eight PX statements for the outpatient clinic and five statements for the ward. Compared to satisfaction surveys, the developed surveys emphasize the aspects of parent's attitude towards the illness, support for families, and daily arrangements with a child patient. © 2019 American Psychological Association Inc.

    Background and objectives Increased donor age is one of the most important risk factors for delayed graft function (DGF), and previous studies suggest that the harmful effect of cold ischemia time is increased in kidneys from older donors. Our aim was to study the association of increased donor age and cold ischemia time with the risk of delayed graft function in a large cohort kidney transplants from the current era. Design, setting, participants, & measurements The Scientific Registry of Transplant Recipients was used for this observational, retrospective registry analysis to identify all deceased donor kidney transplantations in the United States between 2010 and September 2018, who were on dialysis pretransplantation (n=90,810). The association of donor age and cold ischemia time with the risk of DGF was analyzed in multivariable models adjusted for recipient characteristics (age, race, sex, diabetes, calculated panel-reactive antibodies, pretransplant dialysis duration) and donor characteristics (cause of death, sex, race, body mass index, creatinine, donation after circulatory death status, history of hypertension, and HLA mismatch). Results Cold ischemia time and donor age were independently associated with the risk of DGF, but the risk of DGF was not statistically significantly lower in donor age categories between 50 and 64 years, compared with donors ?65 years. The harmful association of cold ischemia time was not higher in kidneys from older donors in any age category, not even among donation after circulatory death donors. When donor risk was assessed with kidney donor profile index, although a statistically significant interaction with cold ischemia time was found, no practically meaningful increase in cold-ischemia susceptibility of kidneys with a high kidney donor profile index was found. Conclusions We were unable to demonstrate an association between donor age and DGF. The association of longer cold ischemia time with the risk of DGF was not magnified in older or more marginal donors.

    Seksuaalirikostilastot, jotka perustuvat viranomaisten tietoon tulleisiin raiskauksiin, ovat pitkään olleet noususuuntaiset, mutta edustavat ainoastaan murto-osaa kaikista raiskauksista. Tutkimuksemme tavoitteena oli selvittää muutoksia raiskauksiin liittyvissä tekijöissä 1900-luvun jälkimmäisellä puoliskolla ja näiden mahdollista yhteyttä viranomaisten tietoon tulleiden raiskausten määrän nousuun. Aineistosta kerättiin tietoa laajalti itse tapahtumaan sekä uhriin ja tekijään liittyen. Tiedot kerättiin kaikista Helsingin oikeuslääkäriasemalle seksuaalirikostutkimuksiin tulleista joka kymmenenneltä vuodelta vuodesta 1952 vuoteen 2002. Aineistomme koostuu 378 tapauksesta. Vuodesta 1982 eteenpäin uhrien iässä on nähtävissä selkeä painopisteen siirtymä alle 16-vuotiaista 17-32-vuotiaisiin. Vuotta 2002 lähestyttäessä alati kasvava osa uhreista on tapahtumia edeltävästi käyttänyt alkoholia ja raiskauksia tapahtuu öisin aiempaa useammin. Aineistossamme on kyselytutkimuksiin verrattuna yliedustettuna tapaukset, joissa tekijä on uhrille tuntematon. Tilastoitujen raiskausten määrän nousu liittynee enemmän muutoksiin raiskaukseen suhtautumisessa ja ilmoitusherkkyyden lisääntymiseen kuin raiskausten olosuhteiden muutoksiin.

    Objectives To study whether self-reported health problems predict sickness absence (SA) from work in employees from different industries. Methods The results of a health risk appraisal (HRA) were combined with archival data of SA of 21 608 employees (59% female, 56% clerical). Exposure variables were self-reported health problems, labelled as ' work disability (WD) risk factors' in the HRA, presence of problems with occupational well-being and obesity. Age, socioeconomic grading and the number of SA days 12 months before the survey were treated as confounders. The outcome measure was accumulated SA days during 12-month follow-up. Data were analysed separately for males and females. A Hurdle model with negative binomial response was used to analyse zero-inflated count data of SA. Results The HRA results predicted the number of accumulated SA days during the 12-month follow-up, regardless of occupational group and gender. The ratio of means of SA days varied between 2.7 and 4.0 among those with ' WD risk factors' and the reference category with no findings, depending on gender and occupational group. The lower limit of the 95% CI was at the lowest 2.0. In the Hurdle model, ' WD risk factors', SA days prior to the HRA and obesity were additive predictors for SA and/or the accumulated SA days in all occupational groups. Conclusion Self-reported health problems and obesity predict a higher total count of SA days in an additive fashion. These findings have implications for both management and the healthcare system in the prevention of WD. © Author(s) (or their employer(s)) 2019. Re-use permitted under CC BY-NC. No commercial re-use.

    Despite gastric cancer being rare nowadays in Western countries, it remains one of the leading causes of cancer death worldwide. The course of the disease varies, so the individual gastric cancer patient’s prognosis is difficult to determine. The need for new biomarkers is crucial. The aim of this study was to evaluate the prognostic value of serum matrix metalloproteinase-8, serum tissue inhibitor of metalloproteinase-1, and tissue matrix metalloproteinase-8 in patients with gastric cancer. Preoperative serum samples from 233 patients with gastric cancer were retrospectively analyzed. Serum levels of matrix metalloproteinase-8 were analyzed with immunofluorometric assay, and tissue inhibitor of metalloproteinase-1 levels were determined by enzyme-linked immunosorbent assay. We also determined the tissue expression of matrix metalloproteinase-8 in 276 gastric cancer samples by immunohistochemistry. Survival data and death causes came from patient records, the Population Register Center of Finland, and Statistics Finland. Patients with a low (131 ng/mL) serum matrix metalloproteinase-8 level had a considerably unfavorable prognosis (p = 0.002). Those patients with a high (≥170 ng/mL) serum tissue inhibitor of metalloproteinase-1 level also had a poor prognosis (p <0.001), and the latter remained significant in multivariable analysis (hazard ratio = 1.85; 95% confidence interval: 1.26–2.72; p = 0.002). The molar ratio of serum matrix metalloproteinase-8 and tissue inhibitor of metalloproteinase-1 levels with low (0.30) molar ratios predicted a worse prognosis (p = 0.020). Tissue matrix metalloproteinase-8 did not influence prognosis. These results suggest that serum matrix metalloproteinase-8, tissue inhibitor of metalloproteinase-1, and the ratio of matrix metalloproteinase-8/ tissue inhibitor of metalloproteinase-1 may prove useful biomarkers for prediction of prognosis in patients with gastric cancer. © The Author(s) 2018.
