Prehospital risk stratification in patients with chest pain.

OBJECTIVES: The History, ECG, Age, Risk Factors and Troponin (HEART) Score is a decision support tool applied by physicians in the emergency department developed to risk stratify low-risk patients presenting with chest pain. We assessed the potential value of this tool in prehospital setting, when applied by emergency medical services (EMS), and derived and validated a tool adapted to the prehospital setting in order to determine if it could assist with decisions regarding conveyance to a hospital. METHODS: In 2017, EMS personnel prospectively determined the HEART Score, including point-of-care (POC) troponin measurements, in patients presenting with chest pain, in the north of the Netherlands. The primary endpoint was a major adverse cardiac event (MACE), consisting of acute myocardial infarction or death, within 3 days. The components of the HEART Score were evaluated for their discriminatory value, cut-offs were calibrated for the prehospital setting and sex was substituted for cardiac risk factors to develop a prehospital HEART (preHEART) Score. This score was validated in an independent prospective cohort of 435 patients in 2018. RESULTS: Among 1208 patients prospectively recruited in the first cohort, 123 patients (10.2%) developed a MACE. The HEART Score had a negative predictive value (NPV) of 98.4% (96.4-99.3), a positive predictive value (PPV) of 35.5% (31.8-39.3) and an area under the receiver operating characteristic curve (AUC) of 0.81 (0.78-0.85). The preHEART Score had an NPV of 99.3% (98.1-99.8), a PPV of 49.4% (42.0-56.9) and an AUC of 0.85 (0.82-0.88), outperforming the HEART Score or POC troponin measurements on their own. Similar results were found in a validation cohort. CONCLUSIONS: The HEART Score can be used in the prehospital setting to assist with conveyance decisions and choice of hospitals; however, the preHEART Score outperforms both the HEART Score and single POC troponin measurements when applied by EMS personnel in the prehospital setting.

Limited impact on patient experience of access of a pay for performance scheme in England in the first year.

BACKGROUND: Improvement of access to general practice is a priority in England. In 2006/07 an annual national survey of patient experience of access was introduced, with financial incentives to practices based on the findings of the survey among their own patients. OBJECTIVES: To describe changes in patient experience of access over the first two years of the survey and incentive scheme, and identify respondent and practice characteristics associated with patient experience of access. DESIGN AND METHODS: The study included 222 general practices in the east of England, which had completed the access survey in 2006/07 and 2007/08. We compared proportions of patients reporting satisfaction with different aspects of access in each year. In explanatory regression models, we investigated the associations between improvement of reported access and respondent and practice characteristics. RESULTS: There were some small improvements in reported access between the two surveys, although satisfaction with opening hours declined marginally. The explanatory analysis showed that larger practices, a higher proportion of respondents from ethnic minority groups, and higher deprivation were associated with patient reports of worse access. These variables and practice response rates did not explain the amount of change between the two years. CONCLUSIONS: The launch of the incentive scheme was not followed by convincing improvements in patient experience of access. Practices with deprived populations or with a high proportion of ethnic minority survey respondents are perceived as offering worse access, were not more likely to achieve improvements, and additional support should be considered to help these practices.
