BACKGROUND: Case detection delay (CDD) in leprosy is defined as the period between the onset of the first signs and symptoms and the time of diagnosis. A tool, consisting of a questionnaire and a detailed guide for researchers, which includes photos of typical skin signs and notes on establishing the timing of events, was developed to determine this period of delay in months in recently diagnosed leprosy patients. The aims of the study were to determine the reliability and consistency of this CDD assessment tool. METHODS: This study was conducted in Ethiopia, Mozambique and Tanzania. Two types of consistency were considered: over time (test-retest reliability) and across different researchers (interrater reliability). A CDD questionnaire was administered to 167 leprosy patients who were diagnosed within 6 months prior to their inclusion. One month later, the same or another researcher re-administered the CDD questionnaire to the same patients. Both test-retest and interrater reliability were assessed using the intraclass correlation coefficient (ICC), where a value greater than or equal to 0.7 is considered acceptable. RESULTS: In this study, 10 participants (6.0%) were under 15 years of age, and 56 (33.5%) were women. In the test-retest assessment, the mean CDD from the first and second interviews was 23.7 months (95% CI 14.4-34.8) and 24.0 months (95% CI 14.8-33.2), respectively. The ICC for test-retest reliability was 0.99 (95% CI 0.994-0.997). For the interrater reliability assessment, the first and second interviews revealed a mean CDD of 24.7 months (95% CI 18.2-31.1) and 24.6 months (95% CI 18.7-30.5), respectively, with an ICC of 0.90 (95% CI 0.85-0.94). A standard error of measurement of 0.46 months was found in the test-retest and 1.03 months in the interrater measurement. Most answers given by participants during the first and second interviews were matching (≥86%). Most non-matching answers were

Introduction: Suboptimal doctor-patient communication drives inappropriate prescribing of antibiotics. We evaluated a communication intervention for general practitioners (GPs) in multicultural Dutch cities to improve antibiotic prescribing for respiratory tract infections (RTI). Methods: This was a non-randomized controlled before-after study. The study period was pre-intervention November 2019 – April 2020 and post-intervention November 2021 – April 2022. The intervention consisted of a live training (organized between September and November 2021), an E-learning, and patient material on antibiotics and antibiotic resistance in multiple languages. The primary outcome was the absolute number of prescribed antibiotic courses indicated for RTIs per GP; the secondary outcome was all prescribed antibiotics per GP. We compared the post-intervention differences in the mean number of prescribed antibiotics between the intervention (N = 25) and the control group (N = 110) by using an analysis of covariance (ANCOVA) test, while adjusting for the pre-intervention number of prescribed antibiotics. Additionally, intervention GPs rated the training and their knowledge and skills before the intervention and 3 months thereafter. Results: There was no statistically significant difference in the mean number of prescribed antibiotics for RTI between the intervention and the control group, nor for mean number of overall prescribed antibiotics. The intervention GPs rated the usefulness of the training for daily practice a 7.3 (on a scale from 1–10) and there was a statistically significant difference between pre- and post-intervention on four out of nine items related to knowledge and skills. Discussion: There was no change in GPs prescription behavior between the intervention and control group. However, GPs found the intervention useful and showed some improvement on self-rated knowledge and communication skills.

Background: Leprosy is an infectious disease with a slow decline in global annual caseload in the past two decades. Active case finding and post-exposure prophylaxis (PEP) with a single dose of rifampicin (SDR) are recommended by the World Health Organization as measures for leprosy elimination. However, more potent PEP regimens are needed to increase the effect in groups highest at risk (i.e., household members and blood relatives, especially of multibacillary patients). The PEP++ trial will assess the effectiveness of an enhanced preventive regimen against leprosy in high-endemic districts in India, Brazil, Bangladesh, and Nepal compared with SDR-PEP. Methods: The PEP++ study is a cluster-randomised controlled trial in selected districts of India, Brazil, Bangladesh, and Nepal. Sub-districts will be allocated randomly to the intervention and control arms. Leprosy patients detected from 2015 − 22 living in the districts will be approached to list their close contacts for enrolment in the study. All consenting participants will be screened for signs and symptoms of leprosy and tuberculosis (TB). In the intervention arm, eligible contacts receive the enhanced PEP++ regimen with three doses of rifampicin (150 − 600 mg) and clarithromycin (150 − 500 mg) administered at four-weekly intervals, whereas those in the control arm receive SDR-PEP. Follow-up screening for leprosy will be done for each individual two years after the final dose is administered. Cox’ proportion hazards analysis and Poisson regression will be used to compare the incidence rate ratios between the intervention and control areas as the primary study outcome. Discussion: Past studies have shown that the level of SDR-PEP effectiveness is not uniform across contexts or in relation to leprosy patients. To address this, a number of recent trials are seeking to strengthen PEP regimens either through the use of new medications or by increasing the d

Background Contact tracing has been a key component of COVID-19 outbreak control. Backward contact tracing (BCT) aims to trace the source that infected the index case and, thereafter, the cases infected by the source. Modelling studies have suggested BCT will substantially reduce SARS-CoV-2 transmission in addition to forward contact tracing.AimTo assess the feasibility and impact of adding BCT in practice. Methods We identified COVID-19 cases who were already registered in the electronic database between 19 February and 10 March 2021 for routine contact tracing at the Public Health Service (PHS) of Rotterdam-Rijnmond, the Netherlands (pop. 1.3 million). We investigated if, through a structured questionnaire by dedicated contact tracers, we could trace additional sources and cases infected by these sources. Potential sources identified by the index were approached to trace the source's contacts. We evaluated the number of source contacts that could be additionally quarantined. Results Of 7,448 COVID-19 cases interviewed in the study period, 47% (n = 3,497) indicated a source that was already registered as a case in the PHS electronic database. A potential, not yet registered source was traced in 13% (n = 979). Backward contact tracing was possible in 62 of 979 cases, from whom an additional 133 potential sources were traced, and four were eligible for tracing of source contacts. Two additional contacts traced had to stay in quarantine for 1 day. No new COVID-19 cases were confirmed. Conclusions The addition of manual BCT to control the COVID-19 pandemic did not provide added value in our study setting.

Background: Access to HIV testing is crucial for detection, linkage to treatment, and prevention. In less urbanised areas, reliance on general practitioners (GPs) for HIV testing is probable, as sexual health centres (SHC) are mostly located within urbanised areas. Limited insight into individuals undergoing HIV testing stems from sparse standard registration of demographics at GPs. This cross-sectional study aims (1) to assess and compare HIV testing at the GP and SHC, and (2) to assess population- and provider-specific HIV incidence. Methods: Individual HIV testing data of GPs and SHC were linked to population register data (aged ≥ 15 years, Rotterdam area, 2015–2019). We reported the proportion HIV tested, and compared GP and SHC testing rates with negative binomial generalised additive models. Data on new HIV diagnoses (2015–2019) from the Dutch HIV Monitoring Foundation relative to the population were used to assess HIV incidence. Results: The overall proportion HIV tested was 1.14% for all residents, ranging from 0.41% for ≥ 40-year-olds to 4.70% for Antilleans. The GP testing rate was generally higher than the SHC testing rate with an overall rate ratio (RR) of 1.61 (95% CI: 1.56–1.65), but not for 15-24-year-olds (RR: 0.81, 95% CI: 0.74–0.88). Large differences in HIV testing rate (1.36 to 39.47 per 1,000 residents) and GP-SHC ratio (RR: 0.23 to 7.24) by geographical area were observed. The GPs’ contribution in HIV testing was greater for GP in areas further away from the SHC. In general, population groups that are relatively often tested are also the groups with most diagnoses and highest incidence (e.g., men who have sex with men, non-western). The overall incidence was 10.55 per 100,000 residents, varying from 3.09 for heterosexual men/women to 24.04 for 25–29-year-olds. Conclusions: GPs have a pivotal role in HIV testing in less urbanised areas further away from the SHC, and among some population groups. A relatively high incidence often follows relat

Background: Leprosy is a public health burden in Indonesia with a high number of new cases every year and a high proportion of disability among new cases. Case detection delay (CDD) can contribute to ongoing transmission and increased disability chances among leprosy patients. This study aimed to establish the CDD of leprosy and the factors associated with detection delay in Indonesia. Method: Community-based study with a cross-sectional design. Data were collected through interviews about sociodemographic and behavioral factors, anticipated stigma, and duration of CDD. Leprosy classification and case detection methods were obtained from health service records. A random sample was taken of 126 leprosy patients registered between 1st October 2020 and 31st March 2022 in the Tegal regency in the Central Java Province. Data were analysed by descriptive and analytical statistics using multiple linear regression. Results: The mean CDD, patient delay, and health system delay were 13.0 months, 9.7 months, and 3.2 months, respectively. Factors associated with longer CDD are younger age (below 35 years), male, found through passive case detection, and not having a family member with leprosy. Factors associated with longer patient delay were being younger (below 35 years), being male, not having a family member with leprosy, and anticipated stigma of leprosy. It was not possible to reliably identify factors associated with health system delay. Conclusion: CDD in leprosy should be reduced in Indonesia. The Indonesian National Leprosy Control Program (NLCP) is advised to adopt an integrated intervention programme combining active case detection with targeted health education to reduce CDD and thereby preventing disabilities in people affected by leprosy.

Objectives Areas with high sexually transmitted infection (STI) testing rates may not require additional strategies to improve testing. However, it may be necessary to intervene in areas with elevated STI risk, but with low STI testing rates. We aimed to compare STI-related risk profiles and STI testing rates by geographical area to determine areas for improvement of sexual healthcare access. Design Cross-sectional population-based study. Setting Greater Rotterdam area, the Netherlands (2015-2019). Participants All residents aged 15-45 years. Individual population-based register data were matched with laboratory-based STI testing data of general practitioners (GPs) and the only sexual health centre (SHC). Outcome measures Postal code (PC) area-specific STI risk scores (based on age, migratory background, education level and urbanisation), STI testing rates and STI positivity. Results The study area consists of approximately 500 000 residents aged 15-45 years. Strong spatial variation in STI testing, STI positivity and STI risk was observed. PC area testing rate ranged from 5.2 to 114.9 tests per 1000 residents. Three PC clusters were identified based on STI risk and testing rate: (1) high-high; (2) high-low; (3) low, independently of testing rate. Clusters 1 and 2 had comparable STI-related risk and STI positivity, but the testing rate differed greatly (75.8 vs 33.2 per 1000 residents). Multivariable logistic regression analysis with generalised estimating equation was used to compare residents in cluster 1 and cluster 2. Compared with cluster 1, residents in cluster 2 more often did not have a migratory background, lived in less urbanised areas with higher median household income, and more distant from both GP and SHC. Conclusion The determinants associated with individuals living in areas with high STI-related risk scores and low testing rates provide leads for improvement of sexual healthcare access. Opportunities for further exploration include GP education

Background Case detection delay (CDD) is associated with grade 2 disability (G2D) in leprosy, a substantial disease burden worldwide. The standardized CDD questionnaire was developed to determine the period of CDD and its related factors. In Indonesia, the incidence of leprosy and G2D is high and an instrument to measure CDD is lacking. This study describes the translation and cross-cultural adaptation process and evaluates the CDD questionnaire in the Indonesian context. Methods We first did forward–backward translation into Bahasa Indonesia and cross-culturally adapted the CDD questionnaire. We then performed face-to-face three-step test interviews in a pilot test to evaluate the understanding of leprosy patients and the content validity of the CDD questionnaire (n = 15). Finally, the reliability and construct validity of the CDD questionnaire were tested in 50 leprosy patients in Tegal Regency, Indonesia. Results The interviews showed that leprosy patients understood the CDD questionnaire well. The content and construct validity were adequate according to linguistic validation and statistical hypothesis testing. The internal consistency test with a Cronbach alpha showed that the CDD questionnaire measures one underlying construct. The reproducibility test, including the test–retest reliability and agreement test, indicated excellent reliability. Conclusions The version of the CDD questionnaire in Bahasa Indonesia is an instrument with good validity and reliability to determine CDD in Indonesia. We recommend its implementation in the leprosy control programme of Indonesia for monitoring early case detection and thereby avoiding leprosy disability.

Yaws is a chronic, highly contagious skin and bone infection caused by Treponema pallidum subspecies pertenue, usually affecting children in impoverished and remote communities. Yaws lesions have thick yellow crusts on pink papillomas that ulcerate and leave deep scars. Yaws cases were confirmed in the Liguasan Marsh, Mindanao Island group, Southern Philippines, in 2017, but there were no cases confirmed in the Luzon and Visayas Island groups. We aimed to detect at least one active or latent yaws case in the island groups of Luzon and Visayas. Active yaws surveillance was conducted by inviting healthcare providers to report yaws suspects. Five remote villages were included in the case detection surveys: three in Luzon and two in the Visayas Island groups. Two indigenous peoples communities were included: Aetas of Quezon and Dumagat/Remontados of Rizal provinces. Trained field personnel conducted free skin check-ups of children, household contacts, and community members. Yaws suspects underwent point-of-care serologic tests for T. pallidum and nontreponemal antibodies. A total of 239 participants were screened for skin diseases, and 103 had serologic tests. Only the Aetas of Quezon province, Luzon, had confirmed yaws cases. Nineteen cases (54.3%) were detected among 35 Aetas: five active yaws (four children, one adult), two latent yaws (adults), and 12 past yaws (1 child, 11 adults). An 8-year-old boy had yaws with skeletal deformities. We report the first yaws cases among the Aetas of Quezon, Luzon Island group. Active yaws surveillance and case detection in remote areas and among indigenous peoples should continue.

SETTING: India has the highest number of new TB cases worldwide. The participation of private providers (PPs) in the National TB Elimination Programme (NTEP) has remained suboptimal. OBJECTIVE: To explore the experiences, barriers and facilitators about their participation in the NTEP as perceived by PPs working in varied settings. DESIGN: Focus group discussions and in-depth interviews were used to engage PPs to obtain their views on participation in the NTEP. Framework and thematic content analysis was used to analyse qualitative data. RESULTS: Non-availability of a comprehensive range of diagnostics and lack of flexibility in the NTEP were barriers to participation in NTEP. PPs were predisposed to think that NTEP was for those who could not afford to purchase medications. Attitudes and previous experiences with NTEP made them sceptical about the NTEP regimen. Although more frequent interactions were sought with NTEP, some bitterness about previous interactions was perceived. CONCLUSION: Challenges identified by PPs for the NTEP include improvement of the quality of TB care, especially at the lower levels of care, availability of a comprehensive range of diagnostics, being friendly to PPs and patients, more frequent interactions with PPs, and more caring conversations with patients at NTEP centres.
