Carbon footprint of patient journeys through primary care: a mixed methods approach

Abstract

BackgroundThe NHS has a target of cutting its carbon dioxide (CO 2 ) emissions by 80% below 1990 levels by 2050. Travel comprises 17% of the NHS carbon footprint. This carbon footprint represents the total CO 2 emissions caused directly or indirectly by the NHS. Patient journeys have previously been planned largely without regard to the environmental impact. The potential contribution of 'avoidable' journeys in primary care is significant. AimTo investigate the carbon footprint of patients travelling to and from a general practice surgery, the issues involved, and potential solutions for reducing patient travel. Design and settingA mixed methods study in a medium-sized practice in Yorkshire. MethodDuring March 2012, 306 patients completed a travel survey. GIS maps of patients' travel (modes and distances) were produced. Two focus groups (12 clinical and 13 non-clinical staff) were recorded, transcribed, and analysed using a thematic framework approach. ResultsThe majority (61%) of patient journeys to and from the surgery were made by car or taxi; main reasons cited were 'convenience', 'time saving', and 'no alternative' for accessing the surgery. Using distances calculated via ArcGIS, the annual estimated CO 2 equivalent carbon emissions for the practice totalled approximately 63 tonnes. Predominant themes from interviews related to issues with systems for booking appointments and repeat prescriptions; alternative travel modes; delivering health care; and solutions to reducing travel. ConclusionThe modes and distances of patient travel can be accurately determined and allow appropriate carbon emission calculations for GP practices. Although challenging, there is scope for identifying potential solutions (for example, modifying administration systems and promoting walking) to reduce 'avoidable' journeys and cut carbon emissions while maintaining access to health care.

Carbon footprint of robotically‐assisted laparoscopy, laparoscopy and laparotomy: a comparison

“…The scope of other healthcare carbon footprinting studies has been an all‐encompassing audit of healthcare delivery that, again, assumes the environmental effect of individual clinical processes to be equivalent . This subset of research consistently finds the aggregate contribution of clinical processes to be one factor in assessments that also include non‐clinical processes (e.g.…”

“…Every item in the operating room, including the surgeon, is transported there largely by fossil fuel‐consuming vehicles. The environmental effect of that transport and procurement has been thoroughly addressed in previous research . Our analysis also excludes the GHG emissions arising from the manufacture of capital goods used in the life cycle of the clinical process, as outlined in the BSI PAS 2050 guidelines.…”

Molecular epidemiology of HIV-1 infection in Europe: An overview

“…The Estonian CRF06_cpx strain was likely originated in Africa (Zetterberg et al, 2004), and although it has been reported in other European countries, it is a minority variant in all studies performed outside Estonia. Conversely, subtype A dominates in Latvia and Lithuania, where the HIV-1 epidemic is otherwise very similar and driven by injecting drug use (Andrews et al, 2013;Popa et al, 2013). More recently CRF02_AG has been increasingly detected among PWID in Russia and is probably linked with the CRF02_AG epidemics in Central Asia (Bobkova, 2013).…”

Assisted dying

“…It was interesting to note that both authors of the article Initial management of dyspepsia in primary care were secondary care physicians. 1 In their otherwise practical approach to managing this common problem, no mention was made of upper gastrointestinal symptoms occasionally being the only early warning of possible ovarian malignancy. Many GPs would now consider arranging a CA125 blood test.…”
