---|---|---|
Advanced-level associate clinician | A professional clinician with advanced competencies to diagnose and manage the most common medical, maternal, child health and surgical conditions, including obstetric and gynaecological surgery (e.g., caesarean sections). Advanced-level associate clinicians are generally trained for 4 to 5 years post secondary education in established higher-education institutions and/or 3 years post initial associate clinician training. The clinicians are registered, and their practice is regulated by their national or subnational regulatory authority. | Assistant medical officer, clinical officer (e.g., in Malawi), medical licentiate practitioner, health officer (e.g., Ethiopia), physician assistant, surgical technician, medical technician, nonphysician clinician |
Associate clinician | A professional clinician with basic competencies to diagnose and manage common medical, maternal, child health and surgical conditions. They may also perform minor surgery. The prerequisites and training can be different from country to country. However, associate clinicians are generally trained for 3 to 4 years post secondary education in established higher-education institutions. The clinicians are registered, and their practice is regulated by their national or subnational regulatory authority. | Clinical officer (e.g., in Tanzania, Uganda, Kenya, Zambia), medical assistant, health officer, clinical associate, nonphysician clinician |
Auxiliary nurse | Has some training in secondary school. A period of on-the-job training may be included and sometimes formalized in apprenticeships. An auxiliary nurse has basic nursing skills and no training in nursing decision making. The level of training varies between countries from a few months to 2–3 years. | Auxiliary nurse, nurse assistant, enrolled nurses |
Auxiliary nurse midwife | Has some training in secondary school and typically a period of on-the-job training. Like an auxiliary nurse, an auxiliary nurse midwife has basic nursing skills and no training in nursing decision making. They possess some of the competencies in midwifery but are not fully qualified as midwives. | Auxiliary midwife |
Midwife | A person who has been assessed and registered by a state midwifery regulatory authority or similar regulatory authority. Their education lasts 3, 4 or more years in nursing school and leads to a university or postgraduate university degree or the equivalent. A registered midwife has the full range of midwifery skills. | Registered midwife, midwife, community midwife |
Nurse | A graduate who has been registered to practice after examination by a state board of nurse examiners or similar regulatory authority. Education includes 3, 4 or more years in nursing school and leads to a university or postgraduate university degree or the equivalent. A registered nurse has the full range of nursing skills. | Registered nurse, nurse practicioner, clinical nurse specialist, advance practice nurse, licensed nurse, BS nurse, nurse clinician |
Levels of Evidence | |
---|---|
Level 1 | Evidence obtained from at least one properly designed randomized controlled trial. |
Level II-1 | Evidence obtained from well-designed controlled trials without randomization. |
Level II-2 | Evidence obtained from well-designed cohort or case–control analytic studies, preferably from more than one center or research group. |
Level II-3 | Evidence obtained from multiple time series with or without the intervention. Dramatic results in uncontrolled experiments could also be regarded as this type of evidence. |
Level III | Opinions of respected authorities based on clinical experience, descriptive studies or reports of expert communities. |
Study design | Criteria |
---|---|
Systematic reviews | ■ Comprehensiveness of sources/search strategy used |
■ Standard appraisal of included studies | |
■ Validity of conclusions | |
■ Recency and relevance | |
Case–control studies | ■ Accurate ascertainment of cases |
■ Nonbiased selection of cases/controls with exclusion criteria applied equally to both | |
■ Response rate | |
■ Diagnostic testing procedures applied equally to each group | |
■ Appropriate attention to potential confounding variables | |
Randomized controlled trials (RCTs) and cohort studies | ■ Initial assembly of comparable groups: |
■ For RCTs: adequate randomization, including concealment and whether potential confounders were distributed equally among groups | |
■ For cohort studies: consideration of potential confounders with either restriction or measurement for adjustment in the analysis; consideration of inception cohorts | |
■ Maintenance of comparable groups (includes attrition, crossovers, adherence, contamination) | |
■ Important differential loss to follow-up or overall high loss to follow-up | |
■ Measurements: equal, reliable and valid (includes masking of outcome assessment) | |
■ Clear definition of interventions | |
■ All important outcomes considered | |
■ Analysis: adjustment for potential confounders for cohort studies or intention-to-treat analysis for RCTs | |
Diagnostic accuracy studies | ■ Screening test relevant, available for primary care, adequately described |
■ Study uses a credible reference standard, performed regardless of test results | |
■ Reference standard interpreted independently of screening test | |
■ Handles indeterminate results in a reasonable manner | |
■ Spectrum of patients included in study | |
■ Sample size | |
■ Administration of reliable screening test |

☆Disclosure of interest: none.
☆☆Contribution to authorship: M.I.R. designed the search strategy. M.I.R. and C.G.M. did the data abstraction. Both authors contributed to writing and editing the manuscript.
★Details of ethics approval: As a systematic review of published literature, no ethic submission was required.
★★Implications: Task sharing of female sterilization to midlevel providers is a common practice globally. The evidence for the safety and efficacy of this practice is sparse. The desire to scale up availability of reproductive health services rapidly must not compromise quality of care. Rigorous evaluation and monitoring of programs can assist with both goals.
