Effects of physician-nurse substitution on clinical parameters: a systematic review and meta-analysis.

ABSTRACT:

Background

Physicians' shortage in many countries and demands of high-quality and affordable care make physician-nurse substitution an appealing workforce strategy. The objective of this study is to conduct a systematic review and meta-analysis of randomised controlled trials (RCTs) assessing the impact of physician-nurse substitution in primary care on clinical parameters.

Methods

We systematically searched OVID Medline and Embase, The Cochrane Library and CINAHL, up to August 2012; selected peer-reviewed RCTs comparing physician-led care with nurse-led care on changes in clinical parameters. Study selection and data extraction were performed in duplicate by independent reviewers. We assessed the individual study risk of bias; calculated the study-specific and pooled relative risks (RR) or weighted mean differences (WMD); and performed fixed-effects meta-analyses.

Results

11 RCTs (N = 30,247) were included; most were from Europe, generally small with higher risk of bias. In all studies, nurses provided care for complex conditions including HIV, hypertension, heart failure, cerebrovascular diseases, diabetes, asthma, Parkinson's disease and incontinence. Meta-analyses showed greater reductions in systolic blood pressure (SBP) in favour of nurse-led care (WMD -4.27 mmHg, 95% CI -6.31 to -2.23) but no statistically significant differences between groups in the reduction of diastolic blood pressure (DBP) (WMD -1.48 mmHg, 95%CI -3.05 to -0.09), total cholesterol (TC) (WMD -0.08 mmol/l, 95%CI -0.22 to 0.07) or glycosylated haemoglobin (WMD 0.12%HbAc1, 95%CI -0.13 to 0.37). Of other 32 clinical parameters identified, less than a fifth favoured nurse-led care while 25 showed no significant differences between groups.

Limitations

disease-specific interventions from a small selection of healthcare systems, insufficient quantity and quality of studies, many different parameters.

Conclusions

trained nurses appeared to be better than physicians at lowering SBP but similar at lowering DBP, TC or HbA1c. There is insufficient evidence that nurse-led care leads to better outcomes of other clinical parameters than physician-led care.

Project description:ImportancePopulation-based findings on physician suicide are of great relevance because this is an important and understudied topic.ObjectiveTo evaluate male and female physician suicide risks compared with the general population from 1980 to date and test whether there is a reduction of SMR in cohorts after 1980 compared with before 1980 via a meta-analysis, modeling studies, and a systematic review emphasizing physician suicide risk factors.Data sourcesThis study uses studies retrieved from PubMed, Scielo, PsycINFO, and Lilacs for human studies published by October 3, 2019, using the search term "(((suicide) OR (self-harm) OR (suicidality)) AND ((physicians) OR (doctors)))." Databases were also searched from countries listed in articles selected for review. Data were also extracted from an existing article by other authors to facilitate comparisons of the pre-1980 suicide rate with the post-1980 changes.Study selectionOriginal articles assessing male and/or female physician suicide were included; for the meta-analysis, only cohorts from 1980 to the present were included.Data extraction and synthesisThe preregistered systematic review and meta-analysis followed Cochrane, PRISMA, and MOOSE guidelines. Data were extracted into standardized tables per a prespecified structured checklist, and quality scores were added. Heterogeneity was tested via Q test, I2, and τ2. For pooled effect estimates, we used random-effects models. The Begg and Egger tests, sensitivity analyses, and meta-regression were performed. Proportional mortality ratios were presented when SMR data could not be extracted.Main outcomes and measuresSuicide SMRs for male and female physicians from 1980 to the present and changes over time (before and after 1980).ResultsOf 7877 search results, 32 articles were included in the systematic review and 9 articles and data sets in the meta-analysis. Meta-analysis showed a significantly higher suicide SMR in female physicians compared with women in general (1.46 [95% CI, 1.02-1.91]) and a significantly lower suicide SMR in male physicians compared with men in general (0.67 [95% CI, 0.55-0.79]). Male and female physician SMRs significantly decreased after 1980 vs before 1980 (male physicians: SMR, -0.84 [95% CI, -1.26 to -0.42]; P < .001; female physicians: SMR, -1.96 [95% CI, -3.09 to -0.84]; P = .002). No evidence of publication bias was found.Conclusions and relevanceIn this study, suicide SMR was found to be high in female physicians and low in male physicians since 1980 but also to have decreased over time in both groups. Physician suicides are multifactorial, and further research into these factors is critical.
