Effect of Medical Scribes on Throughput, Revenue, and Patient and Provider Satisfaction: A Systematic Review and Meta-analysis.

STUDY OBJECTIVE: Documentation in the medical record increases clerical burden to clinicians and reduces time available to spend with patients, thereby leading to less efficient care and increased clinician stress. Scribes have been proposed as one approach to reduce this burden on clinicians and improve efficiency. The primary objective of this study is to assess the effect of scribes on throughput, revenue, provider satisfaction, and patient satisfaction in both the emergency department (ED) and non-ED setting.

METHODS: PubMed, Scopus, the Cumulative Index of Nursing and Allied Health Literature, Latin American and Caribbean Health Sciences Literature database, Google Scholar, the Cochrane Database of Systematic Reviews, and the Cochrane Central Register of Controlled Trials were searched for studies assessing the effect of scribes versus no scribes on the following outcomes: patients per hour, relative value units (RVUs) per hour, RVUs per encounter, clinic length of stay, time to disposition, ED length of stay, ED length of stay for admitted patients, ED length of stay for discharged patients, provider satisfaction, and patient satisfaction. Data were dual extracted into a predefined work sheet, and quality analysis was performed with the Newcastle-Ottawa Scale or Cochrane Risk of Bias Tool. Subgroup analyses were planned between ED versus non-ED studies.

RESULTS: We identified 39 studies comprising greater than 562,682 patient encounters. Scribes increased patients treated per hour by 0.30 (95% confidence interval [CI] 0.10 to 0.51). Scribes increased RVUs per encounter by 0.14 (95% CI 0.03 to 0.24) and RVUs per hour by 0.55 (0.30 to 0.80). There was no difference in time to disposition (5.74 minutes; 95% CI -2.63 to 14.10 minutes) or ED length of stay (-3.44 minutes; 95% CI -7.68 to 0.81 minutes), although a difference was found in clinic length of stay (5.74 minutes; 95% CI 0.42 to 11.05 minutes). Fourteen of 16 studies reported favorable provider satisfaction with a scribe. Seven of 18 studies reported favorable patient satisfaction with a scribe. No studies reported negative provider or patient satisfaction with scribes.

CONCLUSION: Overall, we found that scribes improved RVUs per hour, RVUs per encounter, patients per hour, provider satisfaction, and patient satisfaction. However, we did not identify an improvement in ED length of stay. Future studies are needed to determine the cost-benefit effect of scribes and ED volume necessary to support their use.
