Abstract Ore flow has been identified as one of the critical points developing novel mining method Raise Caving (RC). The focus this contribution is on key issues ore-flow and how to encounter them enable a safe, efficient, economic operation. In de-stressing phase RC, narrow, tabular slots are developed via raises, only blast swell drawn, hence they stay filled with blasted material at all tim...

BACKGROUND Hospital readmissions are serious and costly events, and readmission rates are considered to be an indicator of quality in health care management. Several models to identify patients at risk of unplanned readmissions have been developed in Western countries, but little is known about their performance in other countries. This paper reports the possible utility of one such model devel...

HYPOTHESIS To test our hypothesis that unplanned return to the operating room (OR) is a useful quality indicator, we examined how often and for what reasons patients go back to the OR in a broad-based general surgery practice. DESIGN AND SETTING Prospective cohort study at a rural tertiary care center. PATIENTS Consecutive series of 3044 patients undergoing general surgery procedures in the...

BACKGROUND Adverse drug events are a leading cause of hospitalization among older people. Up to half of all medication-related hospitalizations are potentially preventable. The objective of this study was to investigate and compare the association between medication regimen complexity and number of medications with unplanned hospitalizations over a 3-year period. METHODS Data were analyzed fo...

IMPORTANCE Patients undergoing total laryngectomy are at high risk for hospital readmission. Hospital readmissions are increasingly scrutinized because they are used as a metric of quality care and are subject to financial penalties. OBJECTIVE To determine the rate of, reasons for, and risk factors that predict 30-day unplanned readmission for patients undergoing total laryngectomy. DESIGN,...

OBJECTIVE to develop and validate the Drug Derived Complexity Index (DDCI), a predictive model derived from drug prescriptions able to stratify the general population according to the risk of death, unplanned hospital admission, and readmission, and to compare the new predictive index with the Charlson Comorbidity Index (CCI). DESIGN Population-based cohort study, using a record-linkage analy...

BACKGROUND Increasing numbers of elderly patients are undergoing long-term dialysis. However, the role of dialysis in survival and quality of life is unclear, and poor outcomes may be associated with comorbidities rather than with age only. The initiation of unplanned dialysis in elderly patients with chronic kidney disease (CKD) has been reported to be associated with poor survival. We evaluat...

The number of avoidable cardiac arrests and unplanned admissions to ICU in step-down units (SDUs) remains too high. We have previously shown how a data fusion index, based on the integration of vital signs continuously monitored in SDUs, can identify the cardio-respiratory instability which often precedes these adverse events [1]. We show how the correlations between vital signs, captured in a ...

OBJECTIVE To investigate fertility treatment, twin births, and unplanned pregnancies in pregnant women with eating disorders in a population-based sample. DESIGN A longitudinal population-based birth cohort (Generation R). SETTING Rotterdam, the Netherlands. SAMPLE Women from the Generation R study who reported a history of (recent or past) anorexia nervosa (n = 160), bulimia nervosa (n =...

BACKGROUND Integration of family planning services into HIV care was implemented in South Africa as a core strategy aimed at reducing unintended pregnancies among childbearing women living with HIV. However, it is unclear whether this strategy has made any significant impact at the population level. This paper describes the prevalence and correlates of self-reported unplanned pregnancy among HI...
