Foundation of evidence-based decision making for health care managers, part 1: systematic review

Decentralizing evidence-based decision-making in resource limited setting: A case of SNNP region, Ethiopia

BACKGROUND

Access to and the use of accurate, valid, reliable, timely, relevant, legible and complete information is vital for safe and reliable healthcare. Though the study area has been implementing standardized Health Management Information System (HMIS), there was a need for information on how well structures were utilizing information and this study was designed to assess HMIS data utilization.

METHODS

Facility based retrospective study was conducted in Southern Nations Nationalities and People's Region (SNNPR) in April, 2017. We included data from 163 sample facilities. Data use was evaluated by reviewing eight items from performance monitoring system that included activities from problem identification to monitoring of proposed action plans. Each item reviewed was recoded to yes or no and summed to judge overall performance.

RESULTS

About half (52%) of woredas, 26.2% health centers (HCs), 25% hospitals and 6.2% health posts (HPs) reviewed their performance monthly but only 20% woredas, 6.2% HCs, 1.5% HPs and no hospital prepared action plans after reviewing performance. Summary of 8 items assessed showed that majority of facilities (87.5% hospitals, 81.5% HPs and 70.8% HCs) were poor in data utilization.

CONCLUSIONS

Only about half of woredas and below one-fifth of health facilities were utilizing HMIS data and a lot to move to catch-up country's information revolution plan. Lower health care systems should be supported in evidence-based decision-making and progress should be monitored routinely quantitatively and/or qualitatively.

Clinical and Health System Determinants of Venous Thromboembolism Event Rates After Hip Arthroplasty: An International Comparison

BACKGROUND

Routinely collected hospital data provide increasing opportunities to assess the performance of health care systems. Several factors may, however, influence performance measures and their interpretation between countries.

OBJECTIVE

We compared the occurrence of in-hospital venous thromboembolism (VTE) in patients undergoing hip replacement across 5 countries and explored factors that could explain differences across these countries.

METHODS

We performed cross-sectional studies independently in 5 countries: Canada; France; New Zealand; the state of California; and Switzerland. We first calculated the proportion of hospital inpatients with at least one deep vein thrombosis (DVT) or pulmonary embolism by using numerator codes from the corresponding Patient Safety Indicator. We then compared estimates from each country against a reference value (benchmark) that displayed the baseline risk of VTE in such patients. Finally, we explored length of stay, number of secondary diagnoses coded, and systematic use of ultrasound to detect DVT as potential factors that could explain between-country differences.

RESULTS

The rates of VTE were 0.16% in Canada, 1.41% in France, 0.84% in New Zealand, 0.66% in California, and 0.37% in Switzerland, while the benchmark was 0.58% (95% confidence interval, 0.35-0.81). Factors that could partially explain differences in VTE rates between countries were hospital length of stay, number of secondary diagnoses coded, and proportion of patients who received lower limb ultrasound to screen for DVT systematically before hospital discharge. An exploration of the French data showed that the systematic use of ultrasound may be associated with over detection of DVT but not pulmonary embolism.

CONCLUSIONS

In-hospital VTE rates after arthroplasty vary widely across countries, and a combination of clinical, data-related, and health system factors explain some of the variations in VTE rates across countries.

Foundation of evidence-based decision making for health care managers-part II: meta-analysis and applying the evidence

This article is a continuation of a 2-part series that seeks to build the skills of health care managers and supervisors in critically reading and interpreting systematic reviews and meta-analyses. The first article, part I, defined the types of systematic reviews and outlined the process of conducting them. This article, part II, focuses on meta-analysis, a type of systematic review. This article explains the additional procedures associated with meta-analyses and describes the potential shortcomings of both systematic reviews and meta-analyses. Finally, this article provides a way for health care managers and supervisors to appraise systematic reviews and meta-analyses and to determine whether the evidence applies to their problems and settings.
