Development of a Framework to Describe Functions and Practice of Community Health Workers.

There is evidence to support the effectiveness of community health workers (CHWs), as they practice in a wide range of health care settings; yet, the perceived value of CHWs suffers from a lack of uniform credentialing and from a dearth of billing and payment structures to recognize their individual work. In turn, credentialing and billing for the work of CHWs is hampered by widely variable regulation, conflicting job titles and position descriptions, and general confusion about CHW identity, sometimes complicated by service boundaries that overlap with those of other health care and social service occupations. This article presents evidence from a rapid review of the CHW literature from 2003 to 2018. It includes clinical trials, meta-analyses, and policy reports summarizing more than 200 CHW interventions intended to improve patient health status or care delivery. The evidence is used to identify CHW roles, responsibilities, behaviors, and competencies. Four categories of CHW practice are developed from the evidence: peer CHW, general CHW, clinical CHW, and health navigator. A framework is proposed to recognize unique CHW roles, promote and further integrate varied levels of CHW function into health care-related organizations, and to inform decisions regarding certification, education, and payment for CHW services in the United States.

Who are community health workers and what do they do? Development of an empirically derived reporting taxonomy.

Objectives: To develop an empirically-informed reporting taxonomy for Community Health Worker (CHW) services to address concerns about the transparency and consistency of descriptions of these interventions in the existing literature. Methods: We undertook in-depth interviews (n = 43) with CHWs and service staff working in four case studies selected using maximum variation sampling. Interviewees were encouraged to talk about the service, how they had become involved with the service, the CHW role and relationship with clients. Results: Thematic analysis identified recurrent cross-case observations which we classed as 'who CHW are' and 'what CHW do'. CHW's personal characteristics comprised the sub-groups knowledge and skills, personal qualities, similarity to client and voluntary/paid status; role characteristics comprised time and continuity, settings, limited responsibility, core task and enacted philosophies. Conclusions: We have developed a conceptual framework for reporting CHW interventions based on the existing literature and our own empirical work. Compared with existing work in the field, the taxonomy uses nomenclature that minimizes current overlap and confusion, and provides a more complete description of CHW characteristics.

Who is a community health worker? - a systematic review of definitions.

BACKGROUND: Community health workers (CHWs) can play vital roles in increasing coverage of basic health services. However, there is a need for a systematic categorisation of CHWs that will aid common understanding among policy makers, programme planners, and researchers. OBJECTIVE: To identify the common themes in the definitions and descriptions of CHWs that will aid delineation within this cadre and distinguish CHWs from other healthcare providers. DESIGN: A systematic review of peer-reviewed papers and grey literature. RESULTS: We identified 119 papers that provided definitions of CHWs in 25 countries across 7 regions. The review shows CHWs as paraprofessionals or lay individuals with an in-depth understanding of the community culture and language, have received standardised job-related training of a shorter duration than health professionals, and their primary goal is to provide culturally appropriate health services to the community. CHWs can be categorised into three groups by education and pre-service training. These are lay health workers (individuals with little or no formal education who undergo a few days to a few weeks of informal training), level 1 paraprofessionals (individuals with some form of secondary education and subsequent informal training), and level 2 paraprofessionals (individuals with some form of secondary education and subsequent formal training lasting a few months to more than a year). Lay health workers tend to provide basic health services as unpaid volunteers while level 1 paraprofessionals often receive an allowance and level 2 paraprofessionals tend to be salaried. CONCLUSIONS: This review provides a categorisation of CHWs that may be useful for health policy formulation, programme planning, and research.

Exposició a tuberculosi pulmonar en una unitat neonatal: decisions diagnòstiques i terapèutiques / Exposición a tuberculosis pulmonar en una unidad neonatal: decisiones diagnósticas y terapéuticas / Exposure to pulmonary tuberculosis in a neonatal unit: diagnostic and therapeutic decisions

Fonament: els nounats tenen un risc incrementat de patir malaltia tuberculosa greu a causa de la seva condició d'immunosupressió. Objectiu: avaluar la incidència d'infecció tuberculosa o malaltia latent en una cohort de nounats exposats a un treballador sanitari d'una unitat neonatal diagnosticat de malaltia tuberculosa pulmonar, així com descriure les estratègies per al seu diagnòstic i tractament. Mètode: per al cribratge inicial es va fer una prova de tuberculina (PT) i una radiografia (Rx) toràcica. En cas de dubte, es practicaria una tomografia axial computada (TC) i un QuantiFERON(R)-TB Gold test. Descartada la infecció, es va iniciar tractament amb isoniazida fins als 6 mesos. A aquesta edat, es va fer una segona PT. Resultats: seixanta nounats van estar exposats al cas índex. La PT va ser negativa tant a l'inici com als 6 mesos. Un nadó presentava una imatge dubtosa en la radiografia toràcica, però la TC i el QuantiFERON(R)-TB Gold test van ser normals. El 88,6% dels nounats van iniciar profilaxi, es va contraindicar en el 3% i hi va haver negativa dels pares en el 8%. Tan sols un pacient va presentar efectes secundaris per isoniazida. El 78% dels casos va completar la profilaxi. Als 12 mesos no es va detectar cap cas de tuberculosi. Conclusions: la incidència d'infecció tuberculosa en nounats hospitalitzats exposats és baixa, però, a causa de la gravetat potencial, la profilaxi amb isoniazida fins als 6 mesos i un cribratge precoç amb una PT i una Rx toràcica poden ser una estratègia vàlida per minimitzar el risc

Fundamento. Los neonatos tienen un riesgo incrementado de sufrir enfermedad tuberculosa grave dada su condición de inmunosupresión. Objetivo. Evaluar la incidencia de infección tuberculosa o enfermedad latente en una cohorte de neonatos expuestos a un trabajador sanitario de una unidad neonatal diagnosticado de enfermedad tuberculosa pulmonar, así como describir las estrategias para su diagnóstico y tratamiento. Método. Para el cribado inicial se realizó una prueba de tuberculina (PT) yuna radiografía (Rx) torácica. En caso de duda, se practicaría tomografía axial computerizada (TC) y prueba del QuantiFERON®-TB Gold test. Descartada la infección, se inició tratamiento con isoniazida hasta los 6 meses. A esta edad se practicó una segunda PT. Resultados. Sesenta neonatos fueron expuestos. La PT fue negativa tanto al inicio como a los 6 meses. Un neonato presentaba una imagen dudosa en la radiografía torácica, pero la TC y el QuantiFERON®-TB Gold test fueron normales. El 88,6% de los neonatos iniciaron profilaxis, se contraindicó en el 3% y hubo negativa de los padres en el 8%. Tan sólo un paciente presentó efectos secundarios por isoniazida. El 78% de los casos completó la profilaxis. A los 12 meses no se detectó ningún caso de tuberculosis. Conclusiones. La incidencia de infección tuberculosa en neonatos hospitalizados expuestos es baja, pero, debido a la potencial gravedad, la profilaxis con isoniazida hasta los 6 meses y un cribado precoz con una PT y una Rx torácica pueden ser una estrategia válida para minimizar el riesgo (AU)

Background. Neonates have an increased risk to suffer severe tuber culosis due to their immunosuppressed condition. Objective. To assess the incidence of tuberculosis infection or latent disease in a cohort of newborns exposed to a healthcare worker of the neonatal unit, diagnosed with pulmonary tuberculosis disease, as well as describe diagnostic and treatment strategies. Method. Tuberculin skin test (TST) and chest X-rays were performed at the initial screening. Chest computed tomography (CT) and QuantiFERON®-TB Gold test were performed on cases where chest X-ray was not clear. Once all diagnostic tests were negative, infants were treated with isoniazid up to 6 months of age. At this age, a second TST was performed. Results. 60 newborns were exposed. TST were negative at baseline and at 6 months. One infant had an abnormal chest X-ray, with normal findings on CT and QuantiFERON®-TB Gold test. 88.6% neonates started with prophylaxis, it was contraindicated in 3% and was refused by the parents in 8%. Isoniazid was withdrawn due to side effects in only 1 infant. Prophylaxis was completed by 78% of patients. At 12 months, no cases of tuberculosis were reported. Conclusions. The tuberculous infection incidence in hospitalized neonates exposed is low but, due to the potential severity, prophylaxis with isoniazid until 6 months and an early screening with TST and chest X-ray is a valid strategy to minimized risks (AU)
