RESUMO

INTRODUCTION: Screening household contacts of TB patients and providing TB preventive therapy (TPT) is a key intervention to end the TB epidemic. Global and timely implementation of TPT in household contacts, however, is dismal. We adapted the 7-1-7 timeliness metric designed to evaluate and respond to infectious disease outbreaks or pandemics, and assessed the feasibility, enablers and challenges of implementing this metric for screening and management of household contacts of index patients with bacteriologically-confirmed pulmonary TB in Karachi city, Pakistan. METHODS: We conducted an explanatory mixed methods study with a quantitative component (cohort design) followed by a qualitative component (descriptive design with focus group discussions). RESULTS: From January-June 2023, 92% of 450 index patients had their household contacts line-listed within seven days of initiating anti-TB treatment ("first 7"). In 84% of 1342 household contacts, screening outcomes were ascertained within one day of line-listing ("next 1"). In 35% of 256 household contacts eligible for further evaluation by a medical officer (aged ≤5 years or with chest symptoms), anti-tuberculosis treatment, TPT or a decision for no drugs was made within seven days of symptom screening ("second 7"). The principal reason for not starting anti-tuberculosis treatment or TPT was failure to consult a medical officer: only 129(50%) of 256 contacts consulted a medical officer. Reasons for poor performance in the "second 7" component included travel costs to see a medical officer, loss of daily earnings and fear of a TB diagnosis. Field staff reported that timeliness metrics motivated them to take prompt action in household contact screening and TPT provision and they suggested these be included in national guidelines. CONCLUSIONS: Field staff found "7-1-7" timeliness metrics to be feasible and useful. Integration of these metrics into national guidelines could improve timeliness of diagnosis, treatment and prevention of TB within households of index patients.

RESUMO

Background: The quality of pharmacovigilance data is important for guiding medicine safety and clinical practice. In baseline and follow-up studies after introducing interventions to improve the quality of reporting of Individual Case Safety Reports (ICSRs) in Sierra Leone, we compared (a) timeliness and completeness of reporting and (b) patient outcomes classified as 'recovering'. Methods: Baseline (January 2017-December 2021) and follow-up (June 2022-April 2023) studies of ICSRs in the national pharmacovigilance database. Interventions introduced following recommendations from the baseline study included: updating standard operating procedures and guidelines, setting performance targets follow-up of patient outcomes, and training. Results: There were 566 ICSRs in the baseline study and 59 in the follow-up study. Timelines (reporting < 30 days) improved by five-fold (10% at baseline to 47% in follow-up). For the completeness of variables in ICSRs (desired threshold ≥ 90%),this was 44% at baseline and increased to 80% in the follow-up study. 'Recovering' outcomes reduced from 36% (baseline study) to 3% (follow-up study, p < 0.001). Conclusions: Significant improvements in timeliness, completeness, and validation of ICSRs were observed following operational research in Sierra Leone. While enhancing pharmacovigilance and patient safety, this study highlights the important synergistic role operational research can play in improving monitoring and evaluation systems.

RESUMO

(1) Background: Surgical antibiotic prophylaxis (SAP) is important for reducing surgical site infections. The development of a dedicated hospital SAP guideline in the Dhulikhel Hospital was a recommendation from a baseline study on SAP compliance. Compliance with this new guideline was enhanced through the establishment of a hospital committee, the establishment of an antibiotic stewardship program and the funding and training of healthcare professionals. Using the baseline and a follow-up study after introducing dedicated hospital SAP guidelines, we compared: (a) overall compliance with the SAP guidelines and (b) the proportion of eligible and non-eligible patients who received initial and redosing of SAP; (2) Methods: A before-and-after cohort study was conducted to compare SAP compliance between a baseline study (July 2019-December 2019) and a follow-up study (January 2023-April 2023); (3) Results: A total of 874 patients were in the baseline study and 751 in the follow-up study. Overall SAP compliance increased from 75% (baseline) to 85% in the follow-up study (p < 0.001). Over 90% of those eligible for the initial dose of SAP received it in both studies. Inappropriate use for those not eligible for an initial dose was reduced from 50% to 38% (p = 0.04). For those eligible for redosing, this increased from 14% to 22% but was not statistically significant (p = 0.272); (4) Conclusions: Although there is room for improvement, introduction of dedicated SAP guidelines was associated with improved overall SAP compliance. This study highlights the role of operational research in triggering favorable interventions in hospital clinical care.

RESUMO

Many patients with tuberculosis (TB) have comorbidities, risk determinants and disability that co-exist at diagnosis, during and after TB treatment. We conducted an observational cohort study in 11 health facilities in China to assess under routine program conditions (i) the burden of these problems at the start and end of TB treatment and (ii) whether referral mechanisms for further care were functional. There were 603 patients registered with drug-susceptible TB who started TB treatment: 84% were symptomatic, 14% had diabetes, 14% had high blood pressure, 19% smoked cigarettes, 10% drank excess alcohol and in 45% the 6 min walking test (6MWT) was abnormal. Five patients were identified with mental health disorders. There were 586 (97%) patients who successfully completed TB treatment six months later. Of these, 18% were still symptomatic, 12% had diabetes (the remainder with diabetes failed to complete treatment), 5% had high blood pressure, 5% smoked cigarettes, 1% drank excess alcohol and 25% had an abnormal 6MWT. Referral mechanisms for the care of comorbidities and determinants worked well except for mental health and pulmonary rehabilitation for disability. There is need for more programmatic-related studies in other countries to build the evidence base for care of TB-related conditions and disability.

RESUMO

Background: Improving tuberculosis (TB) care in key populations is an operational research priority in the Kyrgyz Republic. Here, we describe the characteristics of TB/HIV co-infected individuals, their affiliations with key country-wide population groups, and their TB treatment outcomes. Methods: This was a cohort study using national programmatic data (2018-2022). The key population groups included people with increased exposure to TB, limited access to TB services, and increased risk of acquiring TB. Results: Among 693 individuals with TB/HIV co-infection, the majority (58%) of individuals were from two regions of the Kyrgyz Republic (Chui and Bishkek). Eighty-four percent (84%) individuals had one or more affiliations to eight key population groups, with 49% of the individuals affiliated to ≥2 groups and 92% of the individuals were on both antiretroviral treatment and cotrimoxazole preventive therapy. Overall, 406 (59%) of the individuals had successful outcomes and 287 (41%) of the individuals had unsuccessful outcomes. Unsuccessful outcomes increased from 36% (n-39) with TB/HIV alone to 47% (n-86) with affiliations to ≥3 key population groups (P-0.03). Unsuccessful outcomes were associated with co-morbidities (diabetes mellitus and hepatitis B/C), migration, alcohol use, and extrapulmonary TB. Conclusions: For a long time, people with TB/HIV co-infection have been recognized as a "double priority". Affiliation to key populations accentuates their status to "triple priority". We advocate for increased attention and equity towards these populations.

RESUMO

INTRODUCTION: Infection prevention and control (IPC) is crucial to limit health care-associated infections and antimicrobial resistance. An operational research study conducted in Sierra Leone in 2021 reported sub-optimal IPC performance and provided actionable recommendations for improvement. METHODS: This was a before-and-after study involving the national IPC unit and all twelve district-level secondary public hospitals. IPC performance in 2021 (before) and in 2023 (after) was assessed using standardized World Health Organization checklists. IPC performance was graded as: inadequate (0-25%), basic (25.1-50%), intermediate (50.1-75%), and advanced (75.1-100%). RESULTS: The overall IPC performance in the national IPC unit moved from intermediate (58%) to advanced (78%), with improvements in all six core components. Four out of six components achieved advanced levels when compared to the 2021 levels. The median score for hospitals moved from basic (50%) to intermediate (59%), with improvements in six of eight components. Three of four gaps identified in 2021 at the national IPC unit and four of seven at hospitals had been addressed by 2023. CONCLUSIONS: The study highlights the role of operational research in informing actions that improved IPC performance. There is a need to embed operational research as part of the routine monitoring of IPC programs.

RESUMO

Objective: This study aimed to determine the performance of infection prevention and control (IPC) programs in eight core components in level 2 and level 3 hospitals across all provinces in Colombia. Methods: This cross-sectional study used self-assessed IPC performance data voluntarily reported by hospitals to the Ministry of Health and Social Protection during 2021. Each of the eight core components of the World Health Organization's checklist in the Infection Prevention and Control Assessment Framework contributes a maximum score of 100, and the overall IPC performance score is the sum of these component scores. IPC performance is graded according to the overall score as inadequate (0-200), basic (201-400), intermediate (401-600) or advanced (601-800). Results: Of the 441 level 2 and level 3 hospitals, 267 (61%) reported their IPC performance. The median (interquartile range [IQR]) overall IPC score was 672 (IQR: 578-715). Of the 267 hospitals reporting, 187 (70%) achieved an advanced level of IPC. The median overall IPC score was significantly higher in private hospitals (690, IQR: 598-725) than in public hospitals (629, IQR: 538-683) (P < 0.001). Among the core components, scores were highest for the category assessing IPC guidelines (median score: 97.5) and lowest for the category assessing workload, staffing and bed occupancy (median score: 70). Median overall IPC scores varied across the provinces (P < 0.001). Conclusions: This countrywide assessment showed that 70% of surveyed hospitals achieved a self-reported advanced level of IPC performance, which reflects progress in building health system resilience. Since only 61% of eligible hospitals participated, an important next step is to ensure the participation of all hospitals in future assessments.

RESUMO

Objectives: To assess antibiotic susceptibility of World Health Organization (WHO) priority bacteria (Acinetobacter baumannii, Escherichia coli, Klebsiella pneumoniae, Salmonella spp., Staphylococcus aureus, and Streptococcus pneumoniae) in blood cultures at the Orinoquía regional hospital in Colombia. Methods: This was cross-sectional study using routine laboratory data for the period 2019-2021. Data on blood samples from patients suspected of a bloodstream infection were examined. We determined: the total number of blood cultures done and the proportion with culture yield; the characteristics of patients with priority bacteria; and the type of bacteria isolated and antibiotic resistance patterns. Results: Of 25 469 blood cultures done, 1628 (6%) yielded bacteria; 774 (48%) of these bacteria were WHO priority pathogens. Most of the priority bacteria isolated (558; 72%) were gram-negative and 216 (28%) were gram-positive organisms. Most patients with priority bacteria (666; 86%) were hospitalized in wards other than the intensive care unit, 427 (55%) were male, and 321 (42%) were ≥ 60 years of age. Of the 216 gram-positive bacteria isolated, 205 (95%) were Staphylococcus aureus. Of the 558 gram-negative priority bacteria isolated, the three most common were Escherichia coli (34%), Klebsiella pneumoniae (28%), and Acinetobacter baumannii (20%). The highest resistance of Staphylococcus aureus was to oxacillin (41%). For gram-negative bacteria, resistance to antibiotics ranged from 4% (amikacin) to 72% (ampicillin). Conclusions: Bacterial yield from blood cultures was low and could be improved. WHO priority bacteria were found in all hospital wards. This calls for rigorous infection prevention and control standards and continued surveillance of antibiotic resistance.

RESUMEN Objetivos. Evaluar la sensibilidad a los antibióticos de las bacterias incluidas en la lista prioritaria de la Organización Mundial de la Salud (OMS) (Acinetobacter baumannii, Escherichia coli, Klebsiella pneumoniae, Salmonella spp., Staphylococcus aureus y Streptococcus pneumoniae) en hemocultivos en el Hospital Regional de la Orinoquía en Colombia. Métodos. Se trata de un estudio transversal que empleó datos rutinarios de laboratorio del período comprendido entre los años 2019 y 2021. Se examinaron datos de muestras de sangre de pacientes con presunción clínica de infección del torrente sanguíneo. Se determinó el número total de hemocultivos realizados y la proporción cultivos con resultados, las características de los pacientes con bacterias prioritarias, así como el tipo de bacterias aisladas y los patrones de resistencia a los antibióticos. Resultados. De 25 469 hemocultivos realizados, se aislaron bacterias en 1628 (6%); 774 (48%) con agentes patógenos prioritarios de la OMS. La mayoría de las cepas bacterianas prioritarias aisladas (558; 72%) eran gramnegativas y 216 (28%), organismos grampositivos. La mayoría de los pacientes con bacterias prioritarias (666; 86%) fueron hospitalizados en salas distintas de la unidad de cuidados intensivos, 427 (55%) eran varones y 321 (42%) tenían 60 años o más. De las 216 bacterias grampositivas aisladas, 205 (95%) eran Staphylococcus aureus. De las 558 bacterias prioritarias gramnegativas aisladas, las tres más comunes fueron Escherichia coli (34%), Klebsiella pneumoniae (28%) y Acinetobacter baumannii (20%). La mayor resistencia de Staphylococcus aureus fue a la oxacilina (41%). Entre las bacterias gramnegativas, la resistencia a los antibióticos varió del 4% (amikacina) al 72% (ampicilina). Conclusiones. El aislamiento de bacterias en los hemocultivos fue bajo y podría mejorarse. Se encontraron bacterias de la lista prioritaria de la OMS en todas las salas del hospital, por lo que es necesario aplicar rigurosas normas de prevención y control de infecciones y realizar una vigilancia continua de la resistencia a los antibióticos.


RESUMO Objetivos. Avaliar a suscetibilidade a antibióticos das bactérias consideradas prioritárias pela Organização Mundial da Saúde (OMS) (Acinetobacter baumannii, Escherichia coli, Klebsiella pneumoniae, Salmonella spp., Staphylococcus aureus e Streptococcus pneumoniae) em hemoculturas coletadas no hospital regional de Orinoquía na Colômbia. Métodos. Estudo transversal utilizando dados laboratoriais de rotina do período 2019-2021. Foram examinados os dados de amostras de sangue de pacientes com suspeita de infecção de corrente sanguínea. Determinamos o número total de hemoculturas realizadas e a proporção de culturas com rendimento, as características dos pacientes com bactérias prioritárias, e o tipo de bactéria isolada e padrões de resistência a antibióticos. Resultados. Das 25.469 hemoculturas realizadas, 1.628 (6%) foram positivas para bactérias, sendo que 774 (48%) dessas bactérias eram da lista de agentes patogênicos prioritários da OMS. A maioria das bactérias prioritárias isoladas (558; 72%) eram gram-negativas e 216 (28%) eram gram-positivas. A maioria dos pacientes com bactérias prioritárias (666; 86%) estava internada em enfermaria, e não em unidade de terapia intensiva. 427 (55%) eram homens e 321 (42%) tinham ≥ 60 anos de idade. Das 216 bactérias gram-positivas isoladas, 205 (95%) eram Staphylococcus aureus. Das 558 bactérias gram-negativas prioritárias isoladas, as três mais frequentes foram Escherichia coli (34%), Klebsiella pneumoniae (28%) e Acinetobacter baumannii (20%). O Staphylococcus aureus apresentou maior resistência à oxacilina (41%). Entre as bactérias gram-negativas, a resistência aos antibióticos variou entre 4% (amicacina) e 72% (ampicilina). Conclusões. O rendimento bacteriano das hemoculturas foi baixo e pode ser melhorado. As bactérias consideradas prioritárias pela OMS foram encontradas em todas as enfermarias do hospital. Os achados exigem normas rigorosas de prevenção e controle de infecção, e vigilância contínua da resistência bacteriana a antibióticos.

RESUMEN Objetivo. El objetivo de este estudio es determinar el desempeño de los programas de prevención y control de infecciones (PCI) en relación con ocho componentes básicos en hospitales de nivel 2 y 3 de todas las provincias de Colombia. Métodos. En este estudio transversal se emplearon datos de autoevaluación del desempeño de los programas de PCI informados voluntariamente al Ministerio de Salud y Protección Social por parte de los hospitales durante el 2021. Cada uno de los ocho componentes básicos de la lista de verificación de la Organización Mundial de la Salud incluidos en el Marco de evaluación de prevención y control de infecciones al nivel de establecimientos de atención de salud recibe una puntuación máxima de 100, y la puntuación general del desempeño del programa es la suma de las puntuaciones de estos componentes. Este desempeño se califica según la puntuación general como inadecuado (0-200), básico (201-400), intermedio (401-600) o avanzado (601-800). Resultados. De los 441 hospitales de nivel 2 y nivel 3, 267 (61%) informaron datos sobre su desempeño. La mediana (rango intercuartil [IQR]) de la puntuación general fue de 672 (IQR: 578-715). De los 267 hospitales que proporcionaron información, 187 (70%) alcanzaron el nivel avanzado. La mediana de la puntuación general fue significativamente mayor en los hospitales privados (690, IQR: 598-725) que en los hospitales públicos (629, IQR: 538-683) (p < 0,001). En el caso de los componentes básicos, las puntuaciones más altas fueron para la categoría que evalúa las directrices de PCI (puntuación mediana: 97,5) y más bajas para la categoría que evalúa la carga de trabajo, la dotación de personal y la ocupación de camas (puntuación mediana: 70). La mediana de las puntuaciones generales de PCI varió entre las provincias (p < 0,001). Conclusiones. Esta evaluación a nivel nacional mostró que el 70% de los hospitales encuestados lograron un nivel avanzado autoinformado del desempeño en cuanto a la PCI, lo que refleja el progreso en fortalecimiento de la resiliencia del sistema de salud. Dado que solo participó el 61% de los hospitales que reunían las condiciones, el siguiente paso importante es garantizar la participación de todos los hospitales en futuras evaluaciones.


RESUMO Objetivo. Este estudo teve o objetivo de determinar o desempenho de programas de prevenção e controle de infecções (PCI) quanto a oito componentes centrais em hospitais secundários e terciários de todas as províncias da Colômbia. Métodos. Este estudo transversal utilizou dados de desempenho autoavaliado de PCI enviados voluntariamente pelos hospitais ao Ministério da Saúde e Proteção Social em 2021. Cada um dos oito componentes centrais da lista de verificação na Estrutura de Avaliação de Prevenção e Controle de Infecções da Organização Mundial da Saúde contribui com uma pontuação máxima de 100. A pontuação total de desempenho de PCI é a soma das pontuações nesses componentes. De acordo com a pontuação total, o desempenho de PCI é classificado nas seguintes categorias: inadequado (0-200), básico (201-400), intermediário (401-600) ou avançado (601-800). Resultados. Dos 441 hospitais secundários e terciários, 267 (61%) informaram o desempenho de PCI. A mediana (intervalo interquartil [IIQ]) da pontuação total de PCI foi 672 (IIQ: 578-715). Dos 267 hospitais que disponibilizaram informações, 187 (70%) alcançaram um nível de PCI avançado. A mediana da pontuação total de PCI foi significativamente maior nos hospitais privados (690, IIQ: 598-725) do que nos públicos (629, IIQ: 538-683) (p < 0,001). Entre os componentes centrais, as pontuações mais altas foram observadas na categoria de avaliação das diretrizes de PCI (pontuação mediana: 97,5), ao passo que as mais baixas ocorreram na categoria de avaliação da carga de trabalho, dotação de pessoal e taxa de ocupação de leitos (pontuação mediana: 70). As medianas das pontuações totais de PCI variaram entre províncias (p < 0,001). Conclusões. Esta avaliação nacional mostrou que 70% dos hospitais pesquisados alcançaram um nível avançado de desempenho autorrelatado de PCI, o que demonstra progresso no desenvolvimento de resiliência no sistema de saúde. Como apenas 61% dos hospitais elegíveis participaram, um próximo passo importante é assegurar a participação de todos os hospitais em futuras avaliações.

RESUMO

INTRODUCTION: Safety of the environment in which vegetables are grown, marketed and consumed is paramount as most are eaten raw. Irrigation sources include open drains and streams, which are often contaminated with human and animal waste due to poor sanitation infrastructure. In irrigated vegetable farms using such sources in Ghana, we assessed Escherichia coli counts, antibiotic resistance patterns and resistant genes on irrigated lettuce. METHODS: A cross-sectional study was conducted between January-May 2022, involving five major vegetable farms in Ghana. RESULTS: Escherichia coli was found in all 25 composite lettuce samples analyzed. Counts expressed in CFU/g ranged from 186 to 3000, with the highest counts found in lettuce irrigated from open drains (1670) and tap water using hose pipes (3000). Among all bacterial isolates, resistance ranged between 49% and 70% for the Watch group of antibiotics, 59% for the Reserved group and 82% were multidrug-resistant. Of 125 isolates, 60 (48%) were extended-spectrum beta-lactamase-producing, of which five (8%) had the blaTEM-resistant gene. CONCLUSIONS: Lettuce was contaminated with Escherichia coli with high levels of antibiotic resistance. We call on the Ghana Ministry of Food and Agriculture, Food and Drugs Authority and other stakeholders to support farmers to implement measures for improving vegetable safety.

RESUMO

Introduction: Qualitative studies are often inadequately reported, making it difficult to judge their appropriateness for decision making in public health. We assessed the publication characteristics and quality of reporting of qualitative and mixed-method studies from the Structured Operational Research and Training Initiative (SORT IT), a global partnership for operational research capacity building. Methods: A cross-sectional analysis of publications to assess the qualitative component using an adapted version of the Consolidated Criteria for Reporting Qualitative Research (COREQ) checklist. Results: In 67 publications involving 18 countries, 32 journals and 13 public health themes, 55 were mixed-methods studies and 12 were qualitative studies. First authorship from low-and-middle-income (LMIC) countries was present in 64 (96%), LMIC last authorship in 55 (82%), and female first authorship in 30 (45%). The mean LMIC institutions represented per publication was five (range 1-11). Sixty-three (94%) publications were open access. Reporting quality was graded as 'good' to 'excellent' in 60 (89%) publications, 'fair' in five (8%) and 'poor' in two (3%). Conclusion: Most SORT IT publications adhered to COREQ standards, while supporting gender equity in authorship and the promotion of LMIC research leadership. SORT IT plays an important role in ensuring quality of evidence for decision making to improve public health.

RESUMO

Background: An efficient ambulance service is a vital component of emergency medical services. We determined the emergency ambulance response and transport times and ambulance exit outcomes in Bhutan. Methods: A cross-sectional study involving real-time monitoring of emergency ambulance deployments managed by a central toll-free (112) hotline (20 October 2021 to 20 January 2022) was carried out. Results: Of 5092 ambulance deployments, 4291 (84%) were inter-facility transfers, and 801 (16%) were for emergencies. Of the latter, 703 (88%) were for non-pregnancy-related emergencies (i.e., medical, surgical, and accidents), while 98 (12%) were for pregnancy-related emergencies. The median ambulance response and patient transport times were 42 (IQR 3-271) and 41 (IQR 2-272) minutes, respectively. The median round-trip distance travelled by ambulances was 18 km (range 1-186 km). For ambulance exit outcomes that were pregnancy-related (n = 98), 89 (91%) reached the health facility successfully, 8 delivered prior to ambulance arrival at the scene or in the ambulance during transport, and 1 had no outcome record. For the remaining 703 non-pregnancy deployments, 29 (4.1%) deployments were deemed not required or refusals, and 656 (93.3%) reached the health facility successfully; 16 (2.3%) died before the ambulance's arrival at the scene, and 2 (0.3%) were not recorded. Conclusions: This first countrywide real-time operational research showed acceptable ambulance exit outcomes.

RESUMO

The transfer of antibiotic resistance from animals to humans is of concern in recent times. One potential source of such transfer is the untreated poultry excreta used as manure in farming. We aim to identify bacterial isolates and antibiotic susceptibility patterns of Escherichia coli in poultry excreta in Sierra Leone. This was a cross-sectional study of fresh poultry excreta samples collected from four commercial poultry sites in Freetown, Sierra Leone, from June−September 2021. Bacterial isolates were tested against eight antibiotics using established standards. Of 100 samples, 93 showed Escherichia coli (93%): of those, eight isolates also had Salmonella (8%). E. coli was 100% resistant to all three 'Watch' drugs (erythromycin, cefoxitin and streptomycin) and tetracycline. E. coli was least resistant to ampicillin (12%), followed by chloramphenicol (35%). The prevalence of multidrug resistance was 95.6%. Multiple antibiotic resistance index ranged from 0.5−0.7 (optimal < 0.2), indicating high prior exposure to antibiotics in these poultries. Such high levels of resistance in E. coli isolated from poultry excreta could pose a serious threat to humans. We recommend (i) routine surveillance to monitor antibiotic resistance in poultry excreta, (ii) using poultry excreta as manure only after treatment and (iii) restricting the use of antibiotics as prophylactics and growth promoters in poultry feeds.

RESUMO

INTRODUCTION: Good Infection prevention and control (IPC) is vital for tackling antimicrobial resistance and limiting health care-associated infections. We compared IPC performance before (2019) and during the COVID-19 (2021) era at the national IPC unit and all regional (4) and district hospitals (8) in Sierra Leone. METHODS: Cross-sectional assessments using standardized World Health Organizations IPC checklists. IPC performance scores were graded as inadequate = 0-25%, basic = 25.1-50%, intermediate = 50.1-75%, and advanced = 75.1-100%. RESULTS: Overall performance improved from 'basic' to 'intermediate' at the national IPC unit (41% in 2019 to 58% in 2021) and at regional hospitals (37% in 2019 to 54% in 2021) but remained 'basic' at district hospitals (37% in 2019 to 50% in 2021). Priority gaps at the national IPC unit included lack of: a dedicated IPC budget, monitoring the effectiveness of IPC trainings and health care-associated infection surveillance. Gaps at hospitals included no assessment of hospital staffing needs, inadequate infrastructure for IPC and lack of a well-defined monitoring plan with clear goals, targets and activities. CONCLUSION: Although there is encouraging progress in IPC performance, it is slower than desired in light of the COVID-19 pandemic. There is urgent need to mobilize political will, leadership and resources and make a quantum leap forward.
