BackgroundSleep quality in hospitalized Canadian General Internal Medicine patients is not well characterized. Our goals were to characterize hospital sleep quality in this population and identify potentially modifiable barriers to good sleep.MethodsGIM inpatients at a quaternary centre in Edmonton, Canada completed a survey, including the Verran-Snyder Halpern (VSH) questionnaire, to characterize the previous night’s sleep within 48 hours prior to discharge. A chart review was also completed to assess comorbidities, discharge diagnoses, and pharmaceutical sleep aid use.ResultsPatients reported significantly worse nighttime sleep duration in hospital compared with home (mean 5.5 versus 7.0 hours per night, p < 0.0001). Sleep quality was poor, as measured by the VSH disturbance (mean 371), effectiveness (190), and supplementation (115) subscales. Variables independently associated with poorer sleep duration in multivariable regression include prior diagnosis of sleep disorder and multi-patient occupancy rooms. Age, sex, admitting diagnosis, length of stay, frequency of vital checks, and use of sleep pharmaceuticals during the index hospitalization were not associated with sleep duration. The most frequently reported reasons for poor sleep included noise (59%), nursing interruptions (30%), uncomfortable beds (18%), bright lights (16%), unfamiliar surroundings (14%), and pain (9%).ConclusionsSleep quality for GIM inpatients is significantly worse in hospital than at home. There is a need to test non-pharmacologic interventions to address the most frequently identified factors causing poor sleep hygiene for GIM inpatients.

Background: Point-of-care ultrasound (POCUS) is increasingly used in internal medicine, but a lack of trained faculty continues to limit the spread of POCUS education. Using a framework based on organizational change theories, this study sought to identify barriers and enablers for hospital-based practicing internists to learn and use POCUS in clinical practice. Methods: We invited practicing internists at six North American institutions to participate in an electronic survey on their opinions regarding 39 barriers and enablers. Results: Of the 342 participants invited, 170 participated (response rate 49.3%). The top barriers were lack of training (79%), lack of handheld ultrasound devices (78%), lack of direct supervision (65%), lack of time to perform POCUS during rounds (65%), and lack of quality assurance processes (53%). The majority of participants (55%) disagreed or strongly disagreed with the statement "My institution provides funding for POCUS training." In general, participants' attitudes towards POCUS were favourable, and future career opportunities and the potential for billing were not considered significant factors by our participants in the decision to learn or use POCUS. Conclusions: This survey confirms the perceived importance of POCUS to practicing internists. To assist in closing faculty development gap, interventions should address training, supervision, quality assurance processes, availability of handheld devices, as well as dedicated time to perform POCUS during clinical care.

Although mean differences from 2-observer auscultation were acceptable, when tested on their owners, most home BP devices were not accurate to within 5 mm Hg. Ensuring acceptable accuracy of the device-owner pairing should be prioritized.

Purpose: Vitamin D De ciency is common, particularly in northern latitudes. We examined the association between vitamin D status and hypertension in late pregnancy.Methods: A case-control study was conducted during two time periods: SeptemberOctober, 2008, and January-March, 2009, in women near term. A case was de ned as having two or more documented blood pressure readings above 140/90 (either/or) at any time during pregnancy (n=78). Controls had at least two blood pressure readings, with none above 140/90 during pregnancy (n=109). Serum 25-hydroxyvitamin D (25(OH)D) was measured in all participants.Results: In the summer, 13% of controls and 29% of the cases had 25(OH) D levels < 50 nmol/L. During the winter, these numbers rose to 44% and 49% respectively. Both cases and controls were more likely to be vitamin D de cient in the winter (p=0.002). ere was a negative correlation between BMI and 25(OH)D (r=-0.202, p=0.002). In univariate analysis, cases had lower 25(OH)D (p=0.046), but also higher body mass index, so that in multivariate analysis 25(OH)D status was no longer signi cant. ere was no di erence in mean oral daily vitamin D intake (dietary intake and supplements, 746 and 785 IU respectively). Controls gained less weight in pregnancy. ere was a negative correlation between the highest blood pressure measured in pregnancy and 25(OH)D levels (r= -0.118; p=0.012).Conclusion: ere is a high prevalence of vitamin D de ciency in pregnant women recruited in Saskatoon, Saskatchewan. Women with low circulating vitamin D concentrations are more likely to have hypertension.
