Evaluating the Effectiveness of a Local Primary Care Incentive Scheme: A Difference-in-Differences Study

National financial incentive schemes for improving the quality of primary care have come under criticism in the United Kingdom, leading to calls for localized alternatives. This study investigated whether a local general practice incentive-based quality improvement scheme launched in 2011 in a city in the North West of England was associated with a reduction in all-cause emergency hospital admissions. Difference-in-differences analysis was used to compare the change in emergency admission rates in the intervention city, to the change in a matched comparison population. Emergency admissions rates fell by 19 per 1,000 people in the years following the intervention (95% confidence interval [17, 21]) in the intervention city, relative to the comparison population. This effect was greater among more disadvantaged populations, narrowing socioeconomic inequalities in emergency admissions. The findings suggest that similar approaches could be an effective component of strategies to reduce unplanned hospital admissions elsewhere.

Does an alignment of employment policies and individual preferences affect intention to stay in the profession? Evidence from Canadian Midwives

BACKGROUND

This study examines whether alignment of actual and preferred employment policies, including compensation method, employment status, and work schedule, affect midwives' intention to stay in the profession. The study further investigates the moderating effect of financial-rewards satisfaction and compares midwives' policy preferences in urban/rural practices.

METHODS

Cross-sectional survey data from 549 midwives across Canada were analysed through descriptive statistics, bivariate correlations, and hierarchical linear regressions. Further regression analysis separated data for urban/rural practicing midwives.

RESULTS

Three-quarters of the respondents are paid through a billable-course-of-care, while only one-third prefer this model. Another one-third prefer a combination of salary and billable-course-of-care. More than three-quarters of the respondents are independent contractors, but half prefer other forms of employee status. Lastly, half prefer a part-time work schedule, while others prefer full-time. Alignment of actual and preferred employment policies significantly explains midwives' intention to stay in the profession. Intentions to stay in the profession for urban midwives is significantly affected by the alignment of actual and preferred compensation methods, but not for rural ones. Both urban and rural midwives report similar preferences for employment status and work schedule policies. Furthermore, satisfaction with financial rewards is significantly associated with their intention to stay.

CONCLUSION

Policymakers can positively influence midwives' intention to stay in the profession by facilitating alignment of their actual and preferred employment policies.

Use of interrupted time series methods in the evaluation of health system quality improvement interventions: a methodological systematic review

BACKGROUND

When randomisation is not possible, interrupted time series (ITS) design has increasingly been advocated as a more robust design to evaluating health system quality improvement (QI) interventions given its ability to control for common biases in healthcare QI. However, there is a potential risk of producing misleading results when this rather robust design is not used appropriately. We performed a methodological systematic review of the literature to investigate the extent to which the use of ITS has followed best practice standards and recommendations in the evaluation of QI interventions.

METHODS

We searched multiple databases from inception to June 2018 to identify QI intervention studies that were evaluated using ITS. There was no restriction on date, language and participants. Data were synthesised narratively using appropriate descriptive statistics. The risk of bias for ITS studies was assessed using the Cochrane Effective Practice and Organisation of Care standard criteria. The systematic review protocol was registered in PROSPERO (registration number: CRD42018094427).

RESULTS

Of 4061 potential studies and 2028 unique records screened for inclusion, 120 eligible studies assessed eight QI strategies and were from 25 countries. Most studies were published since 2010 (86.7%), reported data using monthly interval (71.4%), used ITS without a control (81%) and modelled data using segmented regression (62.5%). Autocorrelation was considered in 55% of studies, seasonality in 20.8% and non-stationarity in 8.3%. Only 49.2% of studies specified the ITS impact model. The risk of bias was high or very high in 72.5% of included studies and did not change significantly over time.

CONCLUSIONS

The use of ITS in the evaluation of health system QI interventions has increased considerably over the past decade. However, variations in methodological considerations and reporting of ITS in QI remain a concern, warranting a need to develop and reinforce formal reporting guidelines to improve its application in the evaluation of health system QI interventions.
