最近，国际上对在一项研究中结合定性和定量方法的兴趣激增-通常称为混合方法研究。这是及时考虑为什么以及如何混合方法研究中使用的卫生服务研究（HSR）。1994年至2004年期间，由英国HSR研究专员资助的75项混合方法研究的提案和报告的文献分析。对从这些研究中抽取的20名研究人员进行了面对面的半结构化访谈。18%（119/647）的HSR研究被归类为混合方法研究。在文献中，综合性是使用混合方法研究的主要驱动力，研究人员希望解决比单独使用定量方法更广泛的问题。受访者详细阐述了这一点，确定了定性研究的必要性，以参与健康，卫生保健干预措施的复杂性，以及研究发生的环境。采用混合方法的动机并不总是基于混合方法研究对解决研究问题的内在价值;它们可能是战略性的，例如，为了获得资金。混合方法的研究中使用的评价，包括随机和非随机设计;调查和实地考察探索性研究;和仪器的开发。研究所采用的方法数量有限，特别是调查和个别访谈，但所用方法的作用范围很广。混合方法研究在英国的高铁中很常见。它的使用是由实用主义而不是原则驱动的，其动机是单独使用定量方法来解决医疗保健研究的复杂性以及其他更具战略性的收益。方法结合在一系列的上下文中，但新兴的方法学的贡献，从HSR领域的混合方法的研究，目前仅限于定性方法和随机对照试验相结合的单一背景。卫生服务研究人员可以进一步促进混合方法研究的发展，在仪器开发，调查和实地考察，以及非随机评价的背景下。
Recently, there has been a surge of international interest in combining qualitative and quantitative methods in a single study – often called mixed methods research. It is timely to consider why and how mixed methods research is used in health services research (HSR). Documentary analysis of proposals and reports of 75 mixed methods studies funded by a research commissioner of HSR in England between 1994 and 2004. Face-to-face semi-structured interviews with 20 researchers sampled from these studies. 18% (119/647) of HSR studies were classified as mixed methods research. In the documentation, comprehensiveness was the main driver for using mixed methods research, with researchers wanting to address a wider range of questions than quantitative methods alone would allow. Interviewees elaborated on this, identifying the need for qualitative research to engage with the complexity of health, health care interventions, and the environment in which studies took place. Motivations for adopting a mixed methods approach were not always based on the intrinsic value of mixed methods research for addressing the research question; they could be strategic, for example, to obtain funding. Mixed methods research was used in the context of evaluation, including randomised and non-randomised designs; survey and fieldwork exploratory studies; and instrument development. Studies drew on a limited number of methods – particularly surveys and individual interviews – but used methods in a wide range of roles. Mixed methods research is common in HSR in the UK. Its use is driven by pragmatism rather than principle, motivated by the perceived deficit of quantitative methods alone to address the complexity of research in health care, as well as other more strategic gains. Methods are combined in a range of contexts, yet the emerging methodological contributions from HSR to the field of mixed methods research are currently limited to the single context of combining qualitative methods and randomised controlled trials. Health services researchers could further contribute to the development of mixed methods research in the contexts of instrument development, survey and fieldwork, and non-randomised evaluations.
