Quality improvement intervention to increase colorectal cancer screening at the primary care setting: a cluster-randomised controlled trial.

BACKGROUND: Approximately 81% of deaths in Argentina are from chronic non-communicable diseases and 21% caused by cancer. Colorectal cancer (CRC) is the second most frequent cancer in Argentina. Even though CRC screening has been recommended for adults from 50 to 75 years old by using a faecal immunochemical test (FIT) annually, screening rates remain below 20% in the country. METHODS: We conducted an 18-month, two-arm, pragmatic cluster-randomised controlled trial evaluating the effect of a quality improvement intervention, based on the Plan-Do-Study-Act cycles, considering barriers and catalysts to articulate theory and practice, to increase CRC screening rates using FITs at primary care level. The study involved ten public primary health centres in Mendoza province, Argentina. The primary outcome measure was the rate of effective CRC screening. Secondary outcomes were the rate of participants with a positive FIT, tests with invalid results and the rate of participants referred for colonoscopy. RESULTS: Screening was effective in 75% of the participants in the intervention arm vs 54.2% in the control arm, OR 2.5 (95% CI 1.4 to 4.4, p=0.001). These results remained unchanged after adjusting for individual demographic and socioeconomic characteristics. Regarding secondary outcomes, the overall prevalence of positive tests was 17.7% (21.1% in the control arm and 14.7% in the intervention arm, p=0.3648). The overall proportion of participants with inadequate test results was 5.2% (4.9% in the control arm vs 5.5% in the intervention arm, p=0.8516). All the participants with positive tests were referred for colonoscopy in both groups. CONCLUSIONS: An intervention based on quality improvement strategies proved to be highly successful in increasing effective CRC screening in Argentina's primary care setting within the public healthcare system.

Development of physical activity and food built environment quality indicators for chronic diseases in Argentina.

Although obesity and non-communicable disease (NCD) prevention efforts to-date have focused mainly on individual level factors, the social and physical environments in which people live are now widely recognized as important social determinants of health. Obesogenic environments promote higher dietary energy intakes and sedentary behaviors, thus contributing to the obesity/NCD burden. To develop quality indicators (QIs) for measuring food and physical activity (PA)-built environments in municipalities. A literature review was conducted. Based on the best practices identified from this review, a draft set of candidate QI was retrieved. The initial 67 QIs were then evaluated by a modified Delphi panel of multidisciplinary health professionals (n = 40) to determine their relevance, validity, and feasibility in 3 rounds of voting and threaded discussion using a modified RAND/University of California, Los Angeles Appropriateness Methodology. Response rate for the panel was 89.4%. All final 42 QIs were rated as highly relevant, valid, and feasible (median rating ≥ 7 on a 1-9 scale), with no significant disagreement. The final QI set addresses for the PA domain: (i) promotion of PA; and (ii) improvements in the environment to strengthen the practice of PA; and for Food environment domain: (i) promotion of healthy eating; (ii) access to healthy foods; and (iii) promotion of responsible advertising. We generated a set of indicators to evaluate the PA and food built environment, which can be adapted for use in Latin American and other low- and middle-income countries.

The built environment has a considerable effect on health indicators such as physical activity, eating behavior, and community. There is considerable research evidence demonstrating a direct relationship between our built environments and our health. In Argentina, the Healthy Municipalities and Communities Program focuses in health promotion interventions. It was developed to seek collaboration among community members, local government authorities and other stakeholders in order to improve quality of life. However, up to date, there has not been a homogenous measure to evaluate how well a particular locality or a whole municipality supports the health and wellbeing its residents. The proposed study aims to develop a set of local valid and common measures in order to evaluate what is happening within a particular municipality. A designated group of local experts will select a set of final measures trough out an iterative multistage process in order to combine opinion into group consensus. We will ask the panel to rate, discuss and re-rate the proposed measures (based on the existing evidence). This will study provide an evaluative tool to inform policy making and program implementation, and to guide programs and initiatives aimed at combating obesogenic environments in municipalities and communities.

A multifaceted intervention to improve syphilis screening and treatment in pregnant women in Kinshasa, Democratic Republic of the Congo and in Lusaka, Zambia: a cluster randomised controlled trial.

BACKGROUND: Despite international recommendations, coverage of syphilis testing in pregnant women and treatment of those found seropositive remains limited in sub-Saharan Africa. We assessed whether combining the provision of supplies with a behavioural intervention was more effective than providing supplies only, to improve syphilis screening and treatment during antenatal care. METHODS: In this 18-month, cluster randomised controlled trial, we randomly assigned (1:1) 26 urban antenatal care clinics in Kinshasa, Democratic Republic of the Congo, and Lusaka, Zambia, to receive a behavioural intervention (opinion leader selection, academic detailing visits, reminders, audits and feedback, and supportive supervision) plus supplies for syphilis testing and treatment (intervention group) or to receive supplies only (control group). The primary outcomes were proportion of pregnant women who had syphilis screening out of the total who attended the clinic; and the proportion of women who had treatment with benzathine benzylpenicillin out of those who tested positive for syphilis at their first antenatal care visit. This trial is registered at ClinicalTrials.gov, number NCT02353117. FINDINGS: The 18-month study period was Feb 1, 2016, to July 14, 2017. 18 357 women were enrolled at the 13 intervention clinics and 17 679 women were enrolled at the 13 control clinics at their first antenatal care visit. Syphilis screening was done in a median of 99·9% (IQR 99·0-100·0) of women in the intervention clinics and 93·8% (85·0-98·9) in the control clinics (absolute difference 6·1% [95% CI 1·1-14·1]; p=0·00092). Syphilis treatment at the first visit was done in a median of 100% (IQR 99·7-100·0) of seropositive women in intervention clinics and 43·2% (2·6-83·2) of seropositive women in control clinics (absolute difference 56·8% [12·8-99·0]; p=0·0028). INTERPRETATION: A behavioural intervention, together with the provision of supplies, can lead to more than 95% of women being screened and treated for syphilis. The sole provision of supplies is sufficient to reach such levels of screening coverage but is not sufficient to ensure high levels of treatment. FUNDING: Bill & Melinda Gates Foundation.

Single-Use Devices in Argentina: Cost Comparison Analysis of a "Re-Use" versus a "Single-Use" Policy for Trocars, Endocutters, Linear Cutters, and Harmonic Scalpels.

BACKGROUND: Re-use of medical devices labeled and marketed for single use only is a current practice around the world. OBJECTIVES: To estimate the average difference per surgery in device-related costs (DRCs) when performed with single-use devices under a single-use policy (SUP) instead of a re-use policy (RP) from the perspective of the private health sector of Argentina. METHODS: An analytical model was developed in Microsoft Excel and populated with data from a literature review, a Delphi-like panel, and local cost estimations. Four single-use devices were selected for analysis: plastic trocars, endocutters, linear cutters, and harmonic scalpels. DRCs were expressed in 2012 US dollars and divided into four cost categories: devices, adverse events, device failure, and surgical time extension. Outputs were expressed as DRCs per surgery under a SUP, under a RP, the difference between them expressed in US dollars (Diff_$), and the difference between them expressed as a percentage of surgery costs (Diff_%S). Deterministic and probabilistic sensitivity analyses were performed to analyze the impact of uncertainty on results. RESULTS: Expected DRCs per surgery were as follows: for trocars: SUP, US $424.6; RP, US $244.2; Diff_$, US $-180.4; and Diff_%S, -3.8%; for endocutters: SUP, US $1667.4; RP, US $1102.3; Diff_$, US $-565.1; and Diff_%S, -11.1%; for linear cutters: SUP, US $1228.1; RP, US $1045.9; Diff_$, US $-182.2; and Diff_%S, -3.4%; and for harmonic scalpels: SUP, US $1040.9; RP, US $292.4; Diff_$, US $-748.5; and Diff_%S, -14.8%. Sensitivity analyses showed results to be robust. CONCLUSIONS: RP was shown to be less costly in all devices and scenarios considered. Nevertheless, the real frequency of adverse events and their cost implications are still uncertain. More research is needed to assess the effectiveness and safety of these off-label policies.
