Out-of-hours primary care (OOH-PC) has emerged as a promising solution to improve efficiency, accessibility, and quality of care and to reduce the strain on emergency departments. As this modality gains traction in diverse healthcare settings, it is increasingly important to fully assess its societal value-for-money and conduct thorough process evaluations. However, current economic evaluations mostly emphasise direct- and short-term effect measures, thus lacking a broader societal perspective.

This study offers a comprehensive overview of current effect measures in OOH-PC evaluations and proposes additional measures from the evaluation of integrated care programmes.

First, we systematically identified the effect measures from published cost-effectiveness studies and classified them as process, outcome, and resource use measures. Second, we elaborate on the incorporation of ‘productivity gains’, ‘health promotion and early intervention’, and ‘continuity of care’ as additional effects into economic evaluations of OOH-PC. Seeking care affects personal and employee time, potentially resulting in decreased productivity. Challenges in taking time off work and limited access to convenient care are often cited as barriers to accessing primary care. As such, OOH-PC can potentially reduce opportunity costs for patients. Furthermore, improving access to healthcare is important in determining whether people receive promotional and preventive services. Health promotion involves empowering people to take control of their health and its determinants. Given the unscheduled nature and the fragmented or rotational care in OOH-PC, the degree to which interventions and modalities provide continuity should be monitored, assessed, and included in economic evaluations. Continuity of care in primary care improves patient satisfaction, promotes adherence to medical advice, reduces reliance on hospitals, and reduces mortality.

Although it is essential to also address local settings and needs, the integration of broader scope measures into OOH-PC economic evaluations improves the comprehensive evaluation that aligns with welfare gains.

There is a paucity of data guiding treatment duration of oral vancomycin for Clostridiodes difficile infection (CDI) in patients requiring concomitant systemic antibiotics.

To evaluate prescribing practices of vancomycin for CDI in patients that required concurrent systemic antibiotics and to determine whether a prolonged duration of vancomycin (>14 days), compared to a standard duration (10–14 days), decreased CDI recurrence.

In this retrospective cohort study, we evaluated adult hospitalized patients with an initial episode of CDI who were treated with vancomycin and who received overlapping systemic antibiotics for >72 hours. Outcomes of interest included CDI recurrence and isolation of vancomycin-resistant Enterococcus (VRE).

Among the 218 patients included, 36% received a standard duration and 64% received a prolonged duration of treatment for a median of 13 days (11–14) and 20 days (16–26), respectively. Patients who received a prolonged duration had a longer median duration of systemic antibiotic overlap with vancomycin (11 vs 8 days; P < .001) and significantly more carbapenem use and infectious disease consultation. Recurrence at 8 weeks (12% standard duration vs 8% prolonged duration; P = .367), recurrence at 6 months (15% standard duration vs 10% prolonged duration; P = .240), and VRE isolation (3% standard duration vs 9% prolonged duration; P = .083) were not significantly different between groups. Discontinuation of vancomycin prior to completion of antibiotics was an independent predictor of 8-week recurrence on multivariable logistic regression (OR, 4.8; 95% CI, 1.3–18.1).

Oral vancomycin prescribing relative to the systemic antibiotic end date may affect CDI recurrence to a greater extent than total vancomycin duration alone. Further studies are needed to confirm these findings.

Inpatient surgical site infections (SSIs) cause morbidity in children. The SSI rate among pediatric ambulatory surgery patients is less clear. To fill this gap, we conducted a multiple-institution, retrospective epidemiologic study to identify incidence, risk factors, and outcomes.

We identified patients aged <22 years with ambulatory visits between October 2010 and September 2015 via electronic queries at 3 medical centers. We performed sample chart reviews to confirm ambulatory surgery and adjudicate SSIs. Weighted Poisson incidence rates were calculated. Separately, we used case–control methodology using multivariate backward logistical regression to assess risk-factor association with SSI.

In total, 65,056 patients were identified by queries, and we performed complete chart reviews for 13,795 patients; we identified 45 SSIs following ambulatory surgery. The weighted SSI incidence following pediatric ambulatory surgery was 2.00 SSI per 1,000 ambulatory surgeries (95% confidence interval [CI], 1.37–3.00). Integumentary surgeries had the highest weighted SSI incidence, 3.24 per 1,000 ambulatory surgeries (95% CI, 0.32–12). The following variables carried significantly increased odds of infection: clean contaminated or contaminated wound class compared to clean (odds ratio [OR], 9.8; 95% CI, 2.0–48), other insurance type compared to private (OR, 4.0; 95% CI, 1.6–9.8), and surgery on weekend day compared to weekday (OR, 30; 95% CI, 2.9–315). Of the 45 instances of SSI following pediatric ambulatory surgery, 40% of patients were admitted to the hospital and 36% required a new operative procedure or bedside incision and drainage.

Our findings suggest that morbidity is associated with SSI following ambulatory surgery in children, and we also identified possible targets for intervention.

Neuroanatomical abnormalities in first-episode psychosis (FEP) tend to be subtle and widespread. The vast majority of previous studies have used small samples, and therefore may have been underpowered. In addition, most studies have examined participants at a single research site, and therefore the results may be specific to the local sample investigated. Consequently, the findings reported in the existing literature are highly heterogeneous. This study aimed to overcome these issues by testing for neuroanatomical abnormalities in individuals with FEP that are expressed consistently across several independent samples.

Structural Magnetic Resonance Imaging data were acquired from a total of 572 FEP and 502 age and gender comparable healthy controls at five sites. Voxel-based morphometry was used to investigate differences in grey matter volume (GMV) between the two groups. Statistical inferences were made at p < 0.05 after family-wise error correction for multiple comparisons.

FEP showed a widespread pattern of decreased GMV in fronto-temporal, insular and occipital regions bilaterally; these decreases were not dependent on anti-psychotic medication. The region with the most pronounced decrease – gyrus rectus – was negatively correlated with the severity of positive and negative symptoms.

This study identified a consistent pattern of fronto-temporal, insular and occipital abnormalities in five independent FEP samples; furthermore, the extent of these alterations is dependent on the severity of symptoms and duration of illness. This provides evidence for reliable neuroanatomical alternations in FEP, expressed above and beyond site-related differences in anti-psychotic medication, scanning parameters and recruitment criteria.
