INTRODUCTION: Healthcare workforces are currently facing multiple challenges, including aging populations; increasing prevalence of long-term conditions; and shortfall of registered nurses. Employing non-registered support workers is common across many countries to expand service capacity of nursing teams. One task delegated to non-registered support workers is medication administration, which is considered a complex task, with associated risks. This is an important topic given the predicted global increase in patients requiring assistance with medication in community settings. This review explores the evidence on delegation of medication administration from registered nurse to non-registered support workers within community settings, to better understand factors that influence the process of delegation and its impact on service delivery and patient care. METHODS: The review followed key principles of Critical Interpretative Synthesis and was structured around Preferred Reporting Items for Systematic Reviews and Meta‐analysis guidelines. Literature searches were conducted in MEDLINE, CINAHL, Embase, and ProQuest-British Nursing Index databases. Twenty studies were included. RESULTS: Findings are reported under four themes: 1, Regulatory and contextual factors; 2, Individual and team level factors; 3, Outcomes of delegation; and 4, Process of implementation and evaluation. Delegation was found to be a complex phenomenon, influenced by a myriad of interconnecting factors at the macro, meso, micro level. At the macro level, the consistency and clarity of government and state level regulations was found to facilitate or impede delegation of medication administration. Lack of clarity at the macro level, impacted at meso and micro levels, resulting in confusion around what medication administration could be delegated and who held responsibility. At the micro level, central to the interpretation of success was the relationship between the delegator and delegatee. This relationship was influenced by personal views, ...
Objectives: Depression symptom questionnaires are not for diagnostic classification. Patient Health Questionnaire-9 (PHQ-9) scores >= 10 are nonetheless often used to estimate depression prevalence. We compared PHQ-9 >= 10 prevalence to Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (SCID) major depression prevalence and assessed whether an alternative PHQ-9 cutoff could more accurately estimate prevalence. Study Design and Setting: Individual participant data meta-analysis of datasets comparing PHQ-9 scores to SCID major depression status. Results: A total of 9,242 participants (1,389 SCID major depression cases) from 44 primary studies were included. Pooled PHQ-9 >= 10 prevalence was 24.6% (95% confidence interval [CI]: 20.8%, 28.9%); pooled SCID major depression prevalence was 12.1% (95% CI: 9.6%, 15.2%); and pooled difference was 11.9% (95% CI: 9.3%, 14.6%). The mean study-level PHQ-9 >= 10 to SCID-based prevalence ratio was 2.5 times. PHQ-9 >= 14 and the PHQ-9 diagnostic algorithm provided prevalence closest to SCID major depression prevalence, but study-level prevalence differed from SCID-based prevalence by an average absolute difference of 4.8% for PHQ-9 >= 14 (95% prediction interval: -13.6%, 14.5%) and 5.6% for the PHQ-9 diagnostic algorithm (95% prediction interval: -16.4%, 15.0%). Conclusion: PHQ-9 >= 10 substantially overestimates depression prevalence. There is too much heterogeneity to correct statistically in individual studies. ; Canadian Institutes of Health Research (CIHR) KRS-134297 PCG155468 PJT-162206 Fonds de recherche du Quebec -Sante (FRQS) Postdoctoral Training Fellowships FRQS Research Institute of the McGill University Health Centre G.R.

Researchers increasingly use meta-analysis to synthesize the results of several studies in order to estimate a common effect. When the outcome variable is continuous, standard meta-analytic approaches assume that the primary studies report the sample mean and standard deviation of the outcome. However, when the outcome is skewed, authors sometimes summarize the data by reporting the sample median and one or both of (i) the minimum and maximum values and (ii) the first and third quartiles, but do not report the mean or standard deviation. To include these studies in meta-analysis, several methods have been developed to estimate the sample mean and standard deviation from the reported summary data. A major limitation of these widely used methods is that they assume that the outcome distribution is normal, which is unlikely to be tenable for studies reporting medians. We propose two novel approaches to estimate the sample mean and standard deviation when data are suspected to be non-normal. Our simulation results and empirical assessments show that the proposed methods often perform better than the existing methods when applied to non-normal data. ; anadian Institutes of Health Research (CIHR) KRS-134297 Fonds de recherche du Quebec -Sante (FRQS) Canadian Institutes of Health Research (CIHR) Canadian Institutes of Health Research (CIHR) FRQS Masters Training Awards Vanier Canada Graduate Scholarship FRQS Postdoctoral Training Fellowship Research Institute of the McGill University Health Centre G.R.
