Recent years have seen an increasing shift towards providing care in the community, epitomised by the role of Children's Community Nursing (CCN) teams. However, there have been few attempts to use robust evaluative methods to interrogate the impact of such services. This study sought to evaluate whether reduction in secondary care costs, resulting from the introduction of 2 CCN teams, was sufficient to offset the additional cost of commissioning. ⋯ The study represents an important first step in understanding the role of such teams as a means of providing a high quality of paediatric care in an era of limited resource. While the cost saving from released paediatric bed days was not sufficient to demonstrate cost-effectiveness, the analysis does not incorporate wider measures of health care utilisation and nonmonetary benefits resulting from the CCN teams.

Open and honest discussion between healthcare providers and patients and families affected by error is considered to be a central feature of high quality and safer patient care, evidenced by the implementation of open disclosure policies and guidance internationally. This paper discusses the perceived enablers that UK doctors and nurses report as facilitating the enactment of open disclosure. ⋯ Greater openness in relation to adverse events requires health professionals to recognise candour as a professional and moral duty, exemplified in the behaviour of senior clinicians and that seems more likely to occur in a nonpunitive, learning environment. Recognising incident disclosure as part of ongoing respectful and open communication with patients throughout their care is critical.

Diagnostic uncertainty is often encountered in a medical practice. Patients with ambiguous, uncertain, and undiagnosed problems are frequently referred for second opinions. Comparing referral diagnoses to final diagnoses provides an opportunity to determine how frequently final diagnoses vary and changes the direction of medical care. ⋯ Referrals to advanced specialty care for undifferentiated problems are an essential component of patient care. Without adequate resources to handle undifferentiated diagnoses, a potential unintended consequence is misdiagnoses resulting in treatment delays and complications leading to more costly treatments.

Observational Study
Perioperative hypothermia during hip fracture surgery: An observational study.
Elderly patients are at high risk of accidental perioperative hypothermia. The primary objective of this study was to measure the changes in body temperature and the incidence of hypothermia in elderly patients undergoing hip fracture surgery. ⋯ These results indicate that despite the use of active warming methods for most patients, significant hypothermia is still an issue amongst elderly patients undergoing hip fracture surgery. Further improvement is necessary to prevent hypothermia in this high-risk group of patients.

Comparative Study
A comparison of approaches for stratifying on the propensity score to reduce bias.
Stratification is a popular propensity score (PS) adjustment technique. It has been shown that stratifying the PS into 5 quantiles can remove over 90% of the bias due to the covariates used to generate the PS. Because of this finding, many investigators partition their data into 5 quantiles of the PS without examining whether a more robust solution (one that increases covariate balance while potentially reducing bias in the outcome analysis) can be found for their data. Two approaches (referred to herein as PSCORE and PSTRATA) obtain the optimal stratification solution by repeatedly dividing the data into strata until balance is achieved between treatment and control groups on the PS. These algorithms differ in how they partition the data, and it is not known which is better, or if either is better than a 5-quantile default approach, for reducing bias in treatment effect estimates. ⋯ Investigators should routinely use stratification approaches that obtain the optimal stratification solution, rather than simply partitioning the data into 5 quantiles of the PS. Moreover, MMWS (in conjunction with an optimal stratification approach) should be considered as an alternative to IPTW in studies that use PS weights.
