- Case volume per 100 000 population and perioperative mortality rate (POMR) are key indicators to monitor and strengthen surgical services. However, comparisons of POMR have been restricted by absence of standardised approaches to when it is measured, the ideal denominator, need for risk adjustment, and whether data are available. We aimed to address these issues and recommend a minimum dataset by analysing four large mixed surgical datasets, two from well-resourced settings with sophisticated electronic patient information systems and two from resource-limited settings where clinicians maintain locally developed databases.

- The proportion of patients who die during or after surgery, otherwise known as the perioperative mortality rate (POMR), is a credible indicator of the safety and quality of operative care. Its accuracy and usefulness as a metric, however, particularly one that enables valid comparisons over time or between jurisdictions, has been limited by lack of a standardized approach to measurement and calculation, poor understanding of when in relation to surgery it is best measured, and whether risk-adjustment is needed. Our aim was to evaluate the value of POMR as a global surgery metric by addressing these issues using 4, large, mixed, surgical datasets that represent high-, middle-, and low-income countries.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- BACKGROUND: Aggregate and risk-stratified perioperative mortality rates (POMR) are well-documented in high-income countries where surgical databases are common. In many low-income and middle-income country (LMIC) settings, such data are unavailable, compromising efforts to understand and improve surgical outcomes. We undertook a systematic review to determine how POMR is used and defined in LMICs and to inform baseline rates.METHODS: We searched PubMed for all articles published between Jan 1, 2009, and Sept 1, 2014, reporting surgical mortality in LMICs. Search criteria, inclusion and exclusion criteria, and study assessment methodology are reported in the appendix. Titles and abstracts were screened independently by two reviewers. Full-text review and data extraction were completed by four trained clinician coders with regular validation for consistency. We extracted the definition of POMR used, clinical risk scores reported, and strategies for risk adjustment in addition to reported mortality rates.FINDINGS: We screened 2657 abstracts and included 373 full-text articles. 493 409 patients in 68 countries and 12 surgical specialties were represented. The most common definition for the numerator of POMR was in-hospital deaths following surgery (55·3%) and for the denominator it was the number of operative patients (96·2%). Few studies reported preoperative comorbidities (41·8%), ASA status (11·3%), and HIV status (7·8%), with a smaller proportion stratifying on or adjusting mortality for these factors. Studies reporting on planned procedures recorded a median mortality of 1·2% (n=121 [IQR 0·0-4·7]). Median mortality was 10·1% (n=182 [IQR 2·5-16·2) for emergent procedures.INTERPRETATION: POMR is frequently reported in LMICs, but a standardised approach for reporting and risk stratification is absent from the literature. There was wide variation in POMR across procedures and specialties. A quality assessment checklist for surgical mortality studies could improve mortality reporting and facilitate benchmarking across sites and countries.FUNDING: None.

Measuring the migration of surgical specialists
- 2020

Tidskriftsartikel (refereegranskat)abstract
- Background: The lack of access to essential surgical care in low-income countries is aggravated by emigration of locally-trained surgical specialists to more affluent regions. Yet, the global diaspora of surgeons, obstetricians, and anesthesiologists from low-income and middle-income countries has never been fully described and compared with those who have remained in their country of origin. It is also unclear whether the surgical workforce is more affected by international migration than other medical specialists. In this study, we aimed to quantify the proportion of surgical specialists originating from low-income and middle-income countries that currently work in high-income countries. Methods: We retrieved surgical workforce data from 48 high-income countries and 102 low-income and middle-income countries using the database of the World Health Organization Global Surgical Workforce. We then compared this domestic workforce with more granular data on the country of initial medical qualification of all surgeons, anesthesiologists, and obstetricians made available for 14 selected high-income countries to calculate the proportion of surgical specialists working abroad. Results: We identified 1,118,804 specialist surgeons, anesthesiologists, or obstetricians from 102 low-income and middle-income countries, of whom 33,021 (3.0%) worked in the 14 included high-income countries. The proportion of surgical specialists abroad was greatest for the African and South East Asian regions (12.8% and 12.1%). The proportion of specialists abroad was not greater for surgeons, anesthesiologists, or obstetricians than for physicians and other medical specialists (P = .465). Overall, the countries with the lowest remaining density of surgical specialists were also the countries from which the largest proportion of graduates were now working in high-income countries (P = .011). Conclusion: A substantial proportion of all surgeons, anesthesiologists, and obstetricians from low-income and middle-income countries currently work in high-income countries. In addition to decreasing migration from areas of surgical need, innovative strategies to retain and strengthen the surgical workforce could involve engaging this large international pool of surgical specialists and instructors.

A New Approach to Evidence Synthesis in Traumatic Brain Injury : A Living Systematic Review
- 2021

Forskningsöversikt (refereegranskat)abstract
- Living systematic reviews (LSRs) are online summaries of health care research that are updated as new research becomes available. This new development in evidence synthesis is being trialled as part of the Collaborative European NeuroTrauma Effectiveness Research in Traumatic Brain Injury (CENTER-TBI) project. We will develop and sustain an international TBI knowledge community that maintains up-to-date, high quality LSRs of the current state of knowledge in the most important questions in TBI. Automatic search updates will be run three-monthly, and newly identified studies incorporated into the review. Review teams will seek to publish journal updates at regular intervals, with abridged updates available more frequently online. Future project stages include the integration of LSR and other study findings into "living" clinical practice guidance. It is hoped these efforts will go some way to bridging current temporal disconnects between evidence, guidelines, and practice in TBI.
