Abstract

Study Design: Systematic review. Objective: To evaluate the effectiveness of pipelines in increasing enrollment of underrepresented students into graduate healthcare programs. Materials and Methods: Eight databases (CINAHL, Medline, Nursing and Allied Health Premium, OVID, ScienceDirect, Education Index, Proquest, Google Scholar) were searched in October 2021. Inclusion criteria: studies investigating the effect of pipeline programs on enrollment of underrepresented students in individual graduate healthcare programs within the USA. Studies evaluating a pipeline program where students went on to be enrolled at another institution were excluded. Two reviewers screened articles, extracted data and assessed study quality, with a third reviewer resolving disputes. Primary data collected was percentage of underrepresented students enrolled per cohort. Additional data included the profession of the healthcare program, entrance point into the pipeline and interventions used in the pipeline. Study quality was assessed using the National Institutes of Health Quality Assessment Tool for pre/post studies with no control group. Results: After duplicates were removed, 1524 studies were evaluated, with five studies included. Following initiation of a pipeline, fifteen institutions reported increased enrollment of underrepresented students, three reported decreased enrollment, and one reported no change. All studies were of low quality for drawing associative conclusions. Conclusion: Pipelines may be effective at increasing underrepresented students enrolled in graduate healthcare programs. Results are limited in scope, representing only medical and dental programs, and lacking in long-term outcomes.

TL;DR

This systematic review evaluated whether pipeline programs increase enrollment of underrepresented minority (URM) students in graduate healthcare programs, finding that 15 of 19 programs reported increased enrollment after pipeline initiation. However, all five included studies were rated low quality for drawing associative conclusions, and evidence was limited to medical and dental programs.

Key findings

  • Of 19 graduate-level healthcare programs (3 medical, 16 dental) across five studies, 15 reported increased URM enrollment following pipeline initiation, three reported decreased enrollment, and one reported no change.
  • All five studies were judged to have poor-quality evidence for drawing associative conclusions, largely due to lack of statistical analysis of power and significance and unclear/ inconsistent delivery of pipeline interventions.
  • Common pipeline components were mentorship (n = 19), academic assistance (n = 18), application assistance (n = 17), financial assistance (n = 16), priority admission (n = 2), and social support/advising after admission (n = 3).
  • Sixteen programs admitted students at the undergraduate level, two at the high school level, and one at a combination of high school and undergraduate levels; the time between pre- and post-pipeline outcomes ranged from one to eleven years, with only one study reporting interim years.

Methods

  • Systematic review conducted per PRISMA guidelines and prospectively registered with PROSPERO (ID CRD42021281463); eight databases (CINAHL, Medline, Nursing and Allied Health Premium, OVID, ScienceDirect, Education Index, Proquest, Google Scholar) were searched in October 2021 with no publication date restrictions.
  • Inclusion criteria: studies investigating the effect of a pipeline on enrollment of URM students within an individual graduate-level clinical healthcare program in the USA; studies where students enrolled at another institution, non-US institutions, or lacking both pre- and post-intervention data were excluded.
  • From 2228 records identified (1524 after duplicate removal), 1407 were excluded on title/abstract and 118 full texts reviewed, yielding five included studies; two reviewers independently screened, extracted data, and assessed quality, with a third resolving disputes. Quality was assessed with the NIH Quality Assessment Tool for pre-post studies with no control group.

Limitations

  • Stated by the authors: (1) homogeneity of health professions included (medical and dental only), (2) low quality of evidence with unclear significance, (3) lack of long-term outcome data, (4) lack of clarity and consistency in applying the pipeline intervention, and (5) age of the included studies (all at least 10 years old).
  • Stated: none of the studies evaluated or reported the significance of enrollment changes, and 18 of 19 programs reported post-pipeline outcomes at only a single time point, making sustainability unclear.
  • Stated: no study commented on the consistency with which services were applied across participants, making it difficult to isolate the effect of the pipeline or any specific component amid potential confounders.
  • Evident from the text: the review's conclusions rest on only five studies, and the authors note generalizability is difficult given the narrow set of professions represented.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
