The effect of COVID-19 on the non-COVID health outcomes of crisis-affected peoples: a systematic review.

BACKGROUND: The COVID-19 pandemic posed considerable risks to populations affected by humanitarian crises in low- and middle-income countries (LMICs). However, there is limited understanding of how the pandemic may have affected non-COVID health outcomes among crisis-affected populations. Our aim was to examine the evidence on the impact of the COVID-19 pandemic on non-COVID-19 health outcomes for crisis-affected populations in LMICs. METHODS: A systematic review methodology was applied following PRISMA guidelines. Eligibility criteria were: crisis-affected populations in LMICS; COVID-19; and all health topics, except for sexual and reproductive health which was covered in a linked review. Five bibliographic databases and additional grey literature sources were searched. The search period was from 2019 to 31 July 2022. Eligible papers were extracted and analysed using a narrative synthesis approach based on the study objectives and relevant health access and systems frameworks. A quality appraisal was also conducted. FINDINGS: 4320 articles were screened, and 15 eligible studies were identified and included in this review. Ten studies collected health outcomes data. Eight related to mental health, which generally showed worse mental health outcomes because of the pandemic, and pandemic-related stressors were identified. Two studies assessed physical health outcomes in children, while none addressed physical health outcomes among adults. Nine studies reported on access to healthcare, revealing worse access levels due to the pandemic and noting key barriers to care. Seven studies reported on the impact on health systems, with key challenges including reduced and distorted health care funding, reduced staff capacity, interrupted medicines and supplies, weak information and mixed-messaging, and weak leadership. All fifteen studies on the social determinants of health, particularly highlighting the effect of increasing poverty, the role of gender, and food insecurity on health outcomes. The quality of papers was limited overall. CONCLUSION: This review found some limited evidence indicating negative mental health effects, increased barriers to accessing care, damage to health systems and magnified impacts on the social determinants of health for crisis-affected people during the COVID-19 pandemic. However, the small number and limited quality of the studies make the overall strength of evidence quite weak.

Surgical antibiotic prophylaxis administration practices.

SETTING: A referral hospital in Kavre, Nepal. OBJECTIVES: To assess 1) compliance with National Antibiotic Treatment Guidelines (NATG), specifically, whether the administration of surgical antibiotic prophylaxis (SAP) (initial dosing and redosing) was in compliance with NATG for patients who were and were not eligible, and 2) development of surgical site infections (SSIs) among patients who underwent surgery in the Department of General Surgery (July-December 2019). DESIGN: This was a retrospective cohort analysis. RESULTS: The analysis included 846 patients, of which 717 (85%) patients were eligible for SAP and 129 (15%) were ineligible. Of those eligible, 708 (99%) received the initial dose; while 65 (50%) of the ineligible did not receive any dose. Of those who received the initial dose, 164 (23%) were eligible for redosing. Of these, only 23 (14%) received at least one redosing and 141 (86%) did not receive it. Overall compliance with NATG was achieved in 75% (632/846) of patients. SSIs occurred in 23 (3%) patients, 8 (35%) of whom did not have SAP administered according to NATG. CONCLUSION: A relatively high overall compliance with NATG for SAP administration was reported. Recommendations were made to improve compliance among those who were ineligible for SAP and those who were eligible for redosing.

LIEU: Un hôpital de référence du district de Kavre, Népal. OBJECTIFS: Évaluer 1) le respect des directives nationales sur les traitements antibiotiques (NATG), plus particulièrement si l'administration d'une antibioprophylaxie chirurgicale (SAP) (dose initiale et nouvelle dose) respectait les directives NATG pour les patients qui y étaient ou non éligibles ; et 2) le développement d'infections du site opératoire (SSI) chez les patients ayant subi une intervention chirurgicale dans le service de Chirurgie Générale (juillet­décembre 2019). MÉTHODE: Il s'agissait d'une analyse de cohorte rétrospective. RÉSULTATS: L'analyse a inclus 846 patients, dont 717 (85%) étaient éligibles à une SAP et 129 (15%) n'y étaient pas éligibles. Parmi ceux qui y étaient éligibles, 708 (99%) ont reçu la dose initiale, alors que 65 (50%) des patients non éligibles n'ont reçu aucune dose. Parmi ceux ayant reçu la dose initiale, 164 (23%) étaient éligibles à une nouvelle dose. Parmi ces derniers, seuls 23 (14%) ont reçu au moins une nouvelle dose et 141 (86%) n'en ont pas reçu. Les directives NATG ont été respectées chez 75% (632/846) des patients. Des SSI ont été observées chez 23 (3%) patients ; pour huit (35%) de ces patients, la SAP n'avait pas été administrée conformément aux directives NATG. CONCLUSION: Un respect global relativement élevé des directives NATG pour l'administration de la SAP a été rapporté. Des recommandations ont été émises pour améliorer le respect de ces directives chez les patients non éligibles à la SAP et chez ceux éligibles à une nouvelle dose.

Attrition during pre-ART and ART time periods among adolescents enrolled in Integrated HIV Care Programme in Myanmar, 2005-2017.

Retaining adolescents (aged 10-19 years), living with HIV (ALHIV) on antiretroviral therapy (ART) is challenging. In Myanmar, 1269 ALHIV were under an Integrated HIV Care (IHC) Programme by June 2017 and their attrition (death and lost to follow-up) rates were not assessed before. We undertook a cohort study using routinely collected data of ALHIV enrolled into HIV care from July 2005 to June 2017 and assessed their attrition rates in June 2018 by time-to-event analysis. Of 1269 enrolled, 197(16%) and of 1054 initiated ART, 224 (21%) had an attrition defining event. The pre-ART and ART attrition rates were 21.8 (95% CI 19.0-25.1) and 6.4 (95% CI 5.6-7.3) per 100 person-years follow-up, respectively. The factors 'at enrolment' that were associated with higher hazards of attrition were: (1) WHO stage 3 or 4; (2) haemoglobin <10 gm/dl; (3) no documented CD4 cell counts, hepatitis B and C test results; and (4) injection drug use. Baseline hazards were high during the initial 1-2 years and after 5-6 years. The pre-ART and ART attrition rates in ALHIV were lower than those in Africa but higher than the children under IHC. This warrants designing and implementing additional care tailored to the needs of ALHIV under IHC.

IPT in people living with HIV in Myanmar: a five-fold decrease in incidence of TB disease and all-cause mortality.

SETTING: Myanmar, a country with a high human immunodeficiency virus-tuberculosis (HIV-TB) burden, where the tuberculin skin test or interferon-gamma release assays are not routinely available for the diagnosis of latent tuberculous infection. OBJECTIVE: To assess the effect of isoniazid (INH) preventive therapy (IPT) on the risk of TB disease and mortality among people living with HIV (PLHIV). DESIGN: A retrospective cohort study of routinely collected data on PLHIV enrolled into care between 2009 and 2014. RESULTS: Of 7177 patients (median age 36 years, interquartile range 31-42; 53% male) included in the study, 1278 (18%) patients received IPT. Among patients receiving IPT, 855 (67%) completed 6 or 9 months of INH. Patients who completed IPT had a significantly lower risk of incident TB than those who never received IPT (adjusted hazard ratio [aHR] 0.21, 95%CI 0.12-0.34) after controlling for potential confounders. PLHIV who received IPT had a significantly lower risk of death than those who never received IPT (PLHIV who completed IPT, aHR 0.25, 95%CI 0.16-0.37; those who received but did not complete IPT, aHR 0.55, 95%CI 0.37-0.82). CONCLUSION: Among PLHIV in Myanmar, completing a course of IPT significantly reduced the risk of TB disease, and receiving IPT significantly reduced the risk of death.

Childhood TB in Myanmar: trends in notification, profile and treatment outcomes in the private sector.

SETTING: Myanmar National Tuberculosis (TB) programme (NTP). OBJECTIVE: To describe 1) the trends in childhood TB (aged ⩾ 14 years) notification from 2014 to 2017 and quantify the private sector contribution to this notification; and 2) the profile and treatment outcomes of childhood TB managed in the private sector in 2016. STUDY DESIGN: This was an observational study involving the review of routine records and reports of the NTP public-private mix (PPM) projects managed by the Myanmar Medical Association and Population Service International. RESULTS: The total number of childhood TB notified has declined from 36 314 in 2014 to 28 723 in 2017 (average annual decline = 2607 cases per year). The private sector contribution to the notification remained between 17% and 19%. Of the 5616 childhood TB cases diagnosed and treated under the two PPM projects in 2016, 99% were clinically diagnosed and 5459 (97.7%) had successful treatment outcomes. Children aged ⩾10 years, males, those with bacteriologically confirmed TB, those treated in the regions or states of Mandalay, Chin and Shan had a higher risk of an unfavourable outcome (lost to follow-up, death, move to second-line treatment and not evaluated). CONCLUSION: Childhood TB notification is showing a declining trend. One of five notified childhood TB cases was diagnosed and treated in the private sector, where the successful treatment rate was high.

Treatment outcome of tuberculosis patients detected using accelerated vs. passive case finding in Myanmar.

SETTING: Several projects involving accelerated or active case finding (ACF) of tuberculosis (TB) cases are being implemented in Myanmar. However, there is a concern that patients detected using ACF have poorer TB treatment outcomes than those detected using passive case finding (PCF). OBJECTIVE: To assess differences in the demographics, clinical profile and treatment outcomes of patients detected using ACF and PCF. DESIGN: Retrospective cohort study of TB patients diagnosed and enrolled for treatment during 2014-2016. RESULTS: Of 16 048 patients enrolled, 2226 (16%) were detected using ACF; the treatment success rate (cured and completed) was 88%. A higher proportion of cases detected using ACF were aged 55 years, human immunodeficiency virus (HIV) negative and sputum smear-positive pulmonary TB. After adjusting for differences in demographic and clinical characteristics, we found that treatment outcomes in patients detected using ACF and PCF were not significantly different (adjusted relative risk [aRR] 0.89, 95%CI 0.78-1.00). Male sex, age  55 years, patients with a previous history of TB and HIV positivity were independently associated with unsuccessful outcomes. CONCLUSION: ACF detected a significant proportion of TB cases in study townships; treatment outcomes in cases detected using ACF and those detected using PCF were similar. More tailored interventions are needed to improve treatment outcomes in patients at a higher risk of unsuccessful treatment outcomes.

How many sputum samples should be examined during follow-up of tuberculosis patients in Myanmar: two or one?

Setting: Ten selected microscopy centres in Sagaing Region, Myanmar, functioning under an external quality assurance system with no reported major errors. Objective: To assess the pattern of serial sputum results (NN, both smear-negative; NP, first smear-negative and second smear-positive; PN, first smear-positive and second smear-negative; and PP, both smear-positive) among follow-up sputum microscopy examinations of tuberculosis (TB) patients (end of intensive phase, mid-continuation phase and end of treatment) conducted from 1 November 2017 to 15 April 2018. Design: Cross-sectional study using secondary data (laboratory registers). Results: Of 2001 examinations, 94 (4.7%) were smear-positive: 66 PP (3.3%), 12 PN (0.6%) and 16 NP (0.8%); 75% of NP results were scanty. The proportion of NP results was 0.8% (95%CI 0.5-1.3), i.e., 125 smears (95%CI 77-200) were required to detect one additional smear-positive result in the second sample. Of the 16 NP results (15 patients), 14 were tested using Xpert® MTB/RIF and none had rifampicin resistance. During the continuation phase of treatment, 13 became smear-negative, one remained smear-positive and one had unknown follow-up smear status. Conclusion: The benefit of the second sputum sample for monitoring anti-tuberculosis treatment was negligible. Given the favourable resource implications (reduced laboratory workload and costs), we recommend changing the policy from two sputum smears to one during follow-up sputum examinations of TB patients.

Contexte : Dix centres de microscopie sélectionnés de la région de Sagaing, Myanmar, fonctionnant avec un système d'assurance de qualité externe sans erreurs majeures rapportées.Objectif : Evaluer les profils de séries de résultats de crachats (NN, deux frottis négatifs ; NP, premier frottis négatif et deuxième frottis positif ; PN, premier frottis positif et deuxième frottis négatif ; et PP, deux frottis positifs) parmi les examens de suivi de microscopie de crachats de patients TB (à la fin de la phase intensive, au milieu de la phase de continuation et à la fin du traitement) réalisés du 1e novembre 2017 au 15 avril 2018.Schéma : Etude transversale grâce à des données secondaires (registres de laboratoire).Résultats : Sur 2001 examens, 94 (4,7%) ont eu un frottis positif : 66 (3,3%) PP ; 12 (0,6%) PN ; 16 (0,8%) NP ; 75% des NP avaient de rares bacilles. La proportion de NP a été de 0,8% (IC95% 0,5­1,3), impliquant qu'il a fallu 125 frottis (IC95% 77­200) pour détecter un frottis positif supplémentaire dans un deuxième échantillon. Sur les 16 NP (15 patients), 14 ont été testés par Xpert® MTB/RIF et aucun n'a eu de résistance à la rifampicine. Lors de la continuation du traitement, 13 sont devenus à frottis négatif, un patient est resté à frottis positif et un autre a eu un frottis de suivi « indéterminé ¼.Conclusion : Le bénéfice du deuxième échantillon de crachats pour le suivi du traitement antituberculeux a été négligeable. Devant les implications favorables en termes de ressources (charge de travail et coûts réduits pour le laboratoire), nous recommandons de modifier la politique de deux frottis de crachats à un seul lors du suivi de patients TB par examens des crachats.

Marco de Referencia: Diez centros de microscopia escogidos en la región de Sagaing de Birmania, que funcionan con un sistema externo de garantía de la calidad y no notifican errores importantes.Objetivos: Evaluar el perfil de los resultados seriados del esputo (NN, ambas baciloscopias negativas; NP, primera baciloscopia negativa y segunda positiva; PN, primera baciloscopia positiva y segunda negativa; y PP, ambas baciloscopias positivas) en las baciloscopias de esputo de seguimiento de los pacientes con tuberculosis (TB) (al final de la fase intensiva, en medio de la fase de continuación y al final del tratamiento), realizadas del 1° de noviembre del 2017 al 15 de abril del 2018.Métodom: Fue este un estudio transversal que utilizó datos secundarios (los registros de laboratorio).Resultados: De las 2001 baciloscopias realizadas, 94 (4,7%) fueron positivas, a saber: 66 (3,3%) PP; 12 (0,6%) PN; 16 (0,8%) NP; 75% de los resultados NP se notificaron como 'escasos bacilos'. La proporción de resultados NP fue 0,8% (IC95% 0,5­1,3), lo cual indica que se precisaron 125 baciloscopias a fin de detectar una baciloscopia positiva adicional en la segunda muestra (IC95% 77­200). De los 16 casos NP (15 pacientes), 14 se examinaron mediante la prueba Xpert® MTB/RIF y ninguno exhibió resistencia a rifampicina. Durante la fase de continuación del tratamiento, en 13 casos la baciloscopia se hizo negativa, uno permaneció positivo y en otro caso el resultado de la baciloscopia de seguimiento era 'desconocido'.Conclusión: La utilidad de una segunda muestra de esputo en la supervisión del tratamiento antituberculoso fue insignificante. Teniendo en cuenta sus repercusiones económicas favorables (disminución de la carga de trabajo y los costos de laboratorio), se recomienda cambiar la norma de practicar dos muestras de esputo por una sola muestra, durante las baciloscopias de seguimiento de los pacientes con TB.

Sputum smear-positive, Xpert® MTB/RIF-negative results: magnitude and treatment outcomes of patients in Myanmar.

Setting: Myanmar's National Tuberculosis Programme (NTP) uses the Xpert® MTB/RIF assay to diagnose rifampicin (RMP) resistance in sputum smear-positive (Sm+) pulmonary tuberculosis (TB) patients. The Xpert test may occasionally yield negative results (Xpert-) for Mycobacterium tuberculosis complex, indicating a false-positive sputum smear result, false-negative Xpert result or infection with non-tuberculous mycobacteria (NTM). Patients with NTM may respond poorly to first-line anti-tuberculosis treatment. Objective: To assess the burden of Sm+, Xpert- results at the national level and treatment outcomes of Sm+, Xpert- patients in Yangon Region. Design: A cohort study involving a retrospective record review of routinely collected NTP data. Result: In 2015 and 2016, 4% of the 25 359 Sm+ patients who underwent Xpert testing nationally were Sm+, Xpert-. Similarly, in the Yangon Region, 5% of the 5301 Sm+ patients were also Xpert- and were treated with first-line anti-tuberculosis regimens. Smear grade (scanty/1+) and age ⩾65 years were associated with Sm+, Xpert- results. The 88% treatment success rate for this group was similar to that of Sm+, Xpert+ patients without RMP resistance. Conclusion: Approximately 4-5% of Sm+ TB patients were Xpert-. There is an urgent need to formulate guidelines on how to reassess and manage these patients.

Contexte : Le programme national tuberculose du Myanmar (PNT) recourt au test Xpert® MTB/RIF pour diagnostiquer la résistance à la rifampicine (RMP) chez les patients atteints de tuberculose (TB) pulmonaire à frottis de crachats positif (Sm+). Les résultats du test Xpert peuvent parfois être négatifs (Xpert­) pour le complexe Mycobacterium tuberculosis indiquant soit un résultat de frottis de crachats faussement positif, soit un résultat de test Xpert faussement négatif ou une infection à mycobactéries non-tuberculeuse (NTM). Les patients atteints de NTM peuvent répondre de façon médiocre au traitement anti-tuberculose de première ligne.Objectif : Evaluer la proportion de patients Sm+/Xpert­ au niveau national et les résultats du traitement dans la région de Yangon.Schéma : Etude de cohorte impliquant une revue rétrospective des dossiers de données recueillies en routine par le PNT.Résultats: Au niveau national, en 2015 et 2016, 4% des 25 359 patients Sm+ qui ont eu un test Xpert ont été Xpert­. De même, dans la région de Yangon, 5% des 5301 patients Sm+ ont été Xpert­ et ils ont été traités avec des protocoles anti-tuberculose de première ligne. Le grade du frottis (rare/1+) et l'âge ⩾ 65 ans ont été associés aux résultats Sm+/Xpert­. Le taux de succès du traitement a été de 88% ce qui a été similaire aux résultats des patients Sm+/Xpert+ sans résistance à la RMP.Conclusion : La proportion de patients TB Sm+/Xpert­ a été d'environ 4­5%. Il y a un besoin urgent de formuler des directives sur la manière de réévaluer et de prendre en charge de façon optimale ces patients.

Marco de referencia: En el Programa Nacional contra la Tuberculosis (PNT) de Birmania se utiliza la prueba Xpert® MTB/RIF con el fin de diagnosticar la resistencia a rifampicina (RMP) en los pacientes con diagnóstico de tuberculosis (TB) pulmonar y baciloscopia positiva (Sm+). El resultado de la prueba Xpert en ocasiones puede ser negativa para el complejo Mycobacterium tuberculosis, lo cual puede corresponder ya sea a un resultado positivo falso de la baciloscopia del esputo, un resultado negativo falso de la prueba Xpert o a la infección por una micobacteria atípica. Los pacientes infectados por micobacterias atípicas pueden tener una respuesta deficiente al tratamiento antituberculoso de primera línea.Objetivo: Evaluar la proporción de casos SM+, Xpert­ a escala nacional y los desenlaces terapéuticos de estos pacientes en la región de Yangon.Método: Se realizó un estudio de cohortes retrospectivo a partir del análisis de los datos corrientes recogidos en las historias clínicas en el PNT.Resultados: A escala nacional, en el 2015 y el 2016, el 4% de los 25 359 pacientes Sm+ que realizaron la prueba Xpert obtuvo un resultado negativo. Asimismo, en la región de Yangon, el 5% de los 5301 pacientes con Sm+ tuvo un resultado negativo de la prueba Xpert y recibió tratamiento con esquemas antituberculosos de primera línea. Los factores que se asociaron con Sm+ y una prueba Xpert­ fueron el grado de la baciloscopia (bacilos escasos o 1+) y la edad a ⩾ 65 años. La tasa de éxito terapéutico en estos casos fue 88%, una proporción equivalente a los desenlaces de los pacientes Sm+ y Xpert+, sin resistencia a RMP.Conclusión: La proporción de pacientes con Sm+ y Xpert­ fue del 4% al 5%. Existe una necesidad urgente de formular directrices sobre la forma reevaluar estos pacientes y tratarlos de manera óptima.
