Main Outcome Measure

Objective. To determine the frequency and interhospital variation of bilirubin testing and identified hyperbilirubinemia in a large health maintenance organization. Design. Retrospective cohort study. Setting. Eleven Northern California Kaiser Permanente hospitals. Subjects. A total of 51 387 infants born in 1995–1996 at ≥36 weeks' gestation and ≥2000 g. Main Outcome Measure. Bilirubin tests and maximum bilirubin levels recorded in the first month after birth. Results. The proportion of infants receiving ≥1 bilirubin test varied across hospitals from 17% to 52%. The frequency of bilirubin levels ≥20 mg/dL (342 μmol/L) varied from .9% to 3.4% (mean: 2.0%), but was not associated with the frequency of bilirubin testing (R2 = .02). Maximum bilirubin levels ≥25 mg/dL (428 μmol/L) were identified in .15% of infants and levels ≥30 mg/dL (513 μmol/L) in .01%. Conclusions. Significant interhospital differences exist in bilirubin testing and frequency of identified hyperbilirubinemia. Bilirubin levels ≥20 mg/dL were commonly identified, but levels ≥25 mg/dL were not.

The Relationship

ObjectiveTo examine the relationship between visit-to-visit systolic blood pressure (SBP) variability and patient-reported outcome measure of disability in multiple sclerosis (MS) patients.DesignA retrospective cohort study of individuals with MS who completed a patient-determined disease steps (PDDS) scale between 2011 and 2015 at an MS specialty clinic.ParticipantsIndividuals with MS for whom both a completed PDDS scale and ≥3 SBP measures within the prior 12 months of the survey were available.Main outcome measureParticipants were grouped into three classes of disability (no or mild (PDDS 0–1), moderate (2–3), severe (4–7)). SBP variability was calculated as within-subject SD using all SBP measures taken during the past 12 months. SBP variability was analysed by Tertile groups.ResultsNinety-two subjects were included in this analysis. Mean PDDS score was 2.22±1.89. Compared with subjects in Tertile 1 (lowest variability), the odds of being in a higher disability group was 3.5 times higher (OR=3.48; 95% CI: 1.08 to 11.25; p=0.037) in Tertile 2 and 5.2 times higher (OR=5.19; 95% CI: 1.53 to 17.61; p=0.008) in Tertile 3 (highest variability), independent of mean SBP, age, sex, race/ethnicity, body mass index and comorbidities (p for trend=0.008). Mean PDDS scores were 1.52±1.18 in Tertile 1, 2.73±1.02 in Tertile 2 and 2.42±0.89 in Tertile 3 after adjusting for the same covariates.ConclusionsOur results show a significant gradient relationship between SBP variability and MS-related disability. More research is needed to determine the underlying pathophysiological relationship between SBP variability and MS disability progression.

ObjectivesTo identify aspects of the organisation and delivery of acute inpatient services for people with dementia that are associated with shorter length of hospital stay.Design and settingRetrospective cohort study of patients admitted to 200 general hospitals in England and Wales.Participants10 106 people with dementia who took part in the third round of National Audit of Dementia.Main outcome measureLength of admission to hospital.ResultsThe median length of stay was 12 days (IQR=6–23 days). People with dementia spent less time in hospital when discharge planning was initiated within 24 hours of admission (estimated effect −0.24, 95% CI: −0.29 to −0.18, p<0.001). People from ethnic minorities had shorter length of stay (difference −0.066, 95% CI: −0.13 to −0.002, p=0.043). Patients with documented evidence of discussions having taken place between their carers and medical staff spent longer in hospital (difference 0.26, 95% CI: 0.21 to 0.32, p<0.001). These associations held true in a subsample of 669 patients admitted with hip fracture and data from 74 hospitals with above average carer-rated quality of care.ConclusionsThe way that services for inpatients with dementia are delivered can influence how long they spend in hospital. Initiating discharge planning within the first 24 hours of admission may help reduce the amount of time that people with dementia spend in hospital.

ObjectivesEvidence showed that the prevalence of sexual violence during the whole human trafficking period was high. However, the distribution of sexual violence along the stages of the trafficking cycle is unclear. This study aimed to determine the prevalence of sexual violence at each stage of trafficking and factors associated with it among Ethiopian trafficked females.DesignA retrospective cohort study was conducted to study trafficking returnees regarding their previous experiences at each stage of trafficking.SettingsData were collected at immigration offices in three border towns of Ethiopia located bordering Sudan, Kenya and Djibouti.ParticipantsSix hundred and seventy-one women who were trafficked from Ethiopia were recruited into the study consecutively. They were recruited when they came back home via the three border towns either by deportation or voluntary return.Outcome measureThe outcome variable was sexual violence.ResultsThe prevalence of sexual violence was estimated at 10% (95% CI 7.9 to 12.5) during predeparture, 35.0% (95% CI 31.5 to 38.7) travelling period, 58.1% (95% CI 54.2 to 61.8) at destination and 19.5% (95% CI 15.2 to 24.6) detention stages. The odds of sexual violence among returnees aged 14–17 years was about twofold when compared with that of women aged 26–49 years (adjusted OR (AOR)=1.97; 95% CI 1.11 to 3.52). Similarly, being smuggled initially (AOR=1.54; 95% CI 1.09 to 1.93), restricted freedom (AOR=1.45; 95% CI 1.13 to 1.86) and time spent at each stage of trafficking (AOR=1.028; 95% CI 1.024 to 1.033) were positively associated with sexual violence.ConclusionsThe prevalence of sexual violence at each stage of trafficking after departure was high. This could imply that victims might be affected by subsequent negative sexual health outcomes. Young age, initially being smuggled and time spent at each stage of the trafficking process were positively associated with the events of sexual violence. Efforts must be made on modifiable factors such as ‘smuggling’ to minimise subsequent sexual violence during trafficking.
