In the late 1990s there was major concern regarding heroin use among the Nunga community in Adelaide. [Nunga is a generic term used for Aboriginal people from South Australia, similar to Koori's from Victoria and Nyungars from south-western Australia.] Heroin use was so common that community members reported that most families were affected by it in some way. There were few Nunga specific services provided, and those mainstream services available were not seen as culturally appropriate or for other reasons were difficult to access. In response to this, the Parks Community Health Centre, together with the Drug and Alcohol Services Council (DASC) [in 2005 the Drug and Alcohol Services Council (DASC) changed its name to Drug and Alcohol Services South Australia (DASSA)], and with the assistance of Nunkuwarrin Yunti Aboriginal Health Service [Adelaide's Aboriginal Community Controlled Health Service, based in the City Centre], commenced a programme offering treatment interventions for Nunga heroin users. The 'Way Out' Program commenced in March 1999. It is multi-faceted and includes an opioid substitution programme which is attracting and maintaining Nunga clients in greater numbers than ever before in South Australia. The programme locates the drug problem within a holistic view of the individual's health. It utilises networks throughout the Nunga community and in recent years has formed a strong working partnership with the Aboriginal Kinship Program [the Aboriginal Kinship Program (Department of Human Services, Metropolitan Health Division) works with Aboriginal families and individuals seeking support for family members in relation to illicit drug issues by providing support, referral, follow-up and advocacy services]. The 'Way Out' Program is succeeding in making essential treatment services available to Aboriginal people using heroin within Adelaide. This article provides an overview of the programme.

ImportanceCommunication and adoption of modern study design and analytical techniques is of high importance for the improvement of clinical research from observational data.ObjectiveTo compare a modern method for statistical inference, including a target trial emulation framework and doubly robust estimation, with approaches common in the clinical literature, such as Cox proportional hazards models.Design, Setting, and ParticipantsThis retrospective cohort study used longitudinal electronic health record data for outcomes at 28-days from time of hospitalization within a multicenter New York, New York, hospital system. Participants included adult patients hospitalized between March 1 and May 15, 2020, with COVID-19 and not receiving corticosteroids for chronic use. Data were analyzed from October 2021 to March 2022.ExposuresCorticosteroid exposure was defined as more than 0.5 mg/kg methylprednisolone equivalent in a 24-hour period. For target trial emulation, exposures were corticosteroids for 6 days if and when a patient met criteria for severe hypoxia vs no corticosteroids. For approaches common in clinical literature, treatment definitions used for variables in Cox regression models varied by study design (no time frame, 1 day, and 5 days from time of severe hypoxia).Main Outcomes and MeasuresThe main outcome was 28-day mortality from time of hospitalization. The association of corticosteroids with mortality for patients with moderate to severe COVID-19 was assessed using the World Health Organization (WHO) meta-analysis of corticosteroid randomized clinical trials as a benchmark.ResultsA total of 3298 patients (median [IQR] age, 65 [53-77] years; 1970 [60%] men) were assessed, including 423 patients who received corticosteroids at any point during hospitalization and 699 patients who died within 28 days of hospitalization. Target trial emulation analysis found corticosteroids were associated with a reduced 28-day mortality rate, from 32.2%; (95% CI, 30.9%-33.5%) to 25.7% (95% CI, 24.5%-26.9%). This estimate is qualitatively identical to the WHO meta-analysis odds ratio of 0.66 (95% CI, 0.53-0.82). Hazard ratios using methods comparable with current corticosteroid research range in size and direction, from 0.50 (95% CI, 0.41-0.62) to 1.08 (95% CI, 0.80-1.47).Conclusions and RelevanceThese findings suggest that clinical research based on observational data can be used to estimate findings similar to those from randomized clinical trials; however, the correctness of these estimates requires designing the study and analyzing the data based on principles that are different from the current standard in clinical research.
