Cholera in India: an analysis of reports, 1997-2006.

OBJECTIVE: To more accurately define the annual incidence of cholera in India, believed to be higher than reported to the World Health Organization (WHO). METHODS: We searched the biomedical literature to extract data on the cases of cholera reported in India from 1997 to 2006 and compared the numbers found to those reported annually to WHO over the same period. The latter were obtained from WHO's annual summaries of reported cholera cases and National health profile 2006, published by India's Central Bureau of Health Intelligence. FINDINGS: Of India's 35 states or union territories, 21 reported cholera cases during at least one year between 1997 and 2006. The state of West Bengal reported cases during all 10 years, while the state of Maharashtra and the union territory of Delhi reported cases during nine, and Orissa during seven. There were 68 outbreaks in 18 states, and 222 038 cases were detected overall. This figure is about six times higher than the number reported to WHO (37 783) over the same period. The states of Orissa, West Bengal, Andaman and Nicobar Islands, Assam and Chhattisgarh accounted for 91% of all outbreak-related cases. CONCLUSION: The reporting of cholera cases in India is incomplete and the methods used to keep statistics on cholera incidence are inadequate. Although the data are sparse and heterogeneous, cholera notification in India is highly deficient.

Feasibility, reliability and validity of a new assessment form for use with basic surgical trainees.

BACKGROUND: To establish feasibility, reliability and validity of a newly designed basic surgical training (BST) assessment form. METHODS: The assessment form was evaluated among trainees on the South-east Scotland BST rotation over 18 months. Feasibility was indicated by response rate. Reliability was determined using test-retest analysis and internal consistency of each domain determined by Cronbach's alpha and item-total correlation. Construct validity was evaluated by determining improvement in performance after 1 year of training. RESULTS: Response rate was high (889 of 984 forms [90%]), with similar representation from all disciplines. A highly significant positive correlation was found between test-retest scores for all domains (rho: I, 0.736; II, 0.875; III, 0.671; IV, 0.826; V, 0.859; P = 0.0001 all domains, Spearman's). Internal consistency was excellent for each domain, with Cronbach's alpha ranging from 0.82 to 0.95. Item-total correlation coefficients were greater than the required 0.4 for all but one task. In 101 assessments carried out after 1 year of training, significant improvement in scores was found for all domains except clinical skills (time 0 to time 1 year median [interquartile range]: I, 81 [26 to 100] to 100 [100 to 100], P = 0.008; II, 17 [-19 to 52] to 72 [36 to 100], P = 0.015; III, 85 [51 to 100] to 100 [87 to 100], P = 0.018; IV, 82 [44 to 100] to 92 [69 to 100], P = 0.211; V, 27 [-33 to 64] to 76 [32 to 100], P = 0.004). CONCLUSIONS: The new assessment form is feasible, reliable and valid and would therefore be suitable for extended use with basic surgical trainees.

Role of the surgical trainee in upper gastrointestinal resectional surgery.

The 'New Deal' set out by the Department of Health in 1991, together with the introduction of specialist 6-year training grades by Calman in 1993, has resulted in a decrease in available training time for surgeons in the UK. There is also an emerging belief that surgical procedures performed by trainees might compromise patient outcome. This study examines the level of trainee experience in a specialist gastrointestinal unit and whether operation by a trainee surgeon adversely affects patient outcome. All patients in the University Department of Surgery, Royal Infirmary, Edinburgh, undergoing oesophagogastric, hepatic or pancreatic resection between January 1994 and December 1996 were entered into the study. The early clinical outcome (in-hospital mortality and morbidity, considered in three groups: anastomotic leak, other technique-related complications and non-technique-related complications) was evaluated with regard to the grade of surgeon (consultant or trainee) performing the operation. Of the 222 patients undergoing major upper gastrointestinal resection during the study period, 100 (45%) were operated on by trainees. Trainees were assisted and closely supervised by consultants in all but six resections. There was no major difference in mortality rate (consultant, 4.1% vs trainee, 5%), incidence of non-technique-related complications (consultant, 6.7% vs trainee, 7.1%), anastomotic leaks (consultant, 10.7% vs trainee, 5%) or technique-related complications (consultant, 18.9% vs trainee, 15%) between the two grades of surgeon. In a specialist unit, the early clinical outcome of patients undergoing major upper gastrointestinal resection by supervised trainees is no worse than in those operated on by consultants. Participation of trainees in such complex procedures enhances surgical training and does not jeopardise patient care.

Preoperative fasting: current practice and areas for improvement.

Preoperative fasting aims to increase patient safety by reducing the risk of adverse events during general anaesthesia. However, prolonged fasting may be associated with dehydration, hypoglycaemia and electrolyte imbalance as well as patient discomfort. We aimed to examine compliance with the current best practice guidelines in a large surgical unit and to identify areas for improvement. Adult patients undergoing elective and emergency general, orthopaedic, gynaecology and vascular surgery procedures in the Royal Infirmary of Edinburgh were surveyed over a 3-month period commencing November 2011. A standardised questionnaire was used to collect information on the duration of preoperative fasting and the advice administered by medical and nursing staff. 292 patients were included. Median fast from solids was 13.5 h for elective patients (IQR 11.5-16) and 17.38 h for emergency patients (IQR 13.68-28.5 h). Similarly, the median fast from fluids was 9.36 h for elective patients (IQR 5.38-12.75 h) and 12.97 h for emergency patients (IQR 8.5-16.22 h). The instructions that elective patients received contributed to prolonged fasting times. The median fast for elective patients fully compliant with fasting advice would be 10 h for solids (IQR 8.75-12 h) and 6.25 h (IQR 3.83-9.25 h) for clear fluids. Elective patients fasted for longer than recommended confirming that clinical practice is slow to change. The use of universal fasting instructions and patient choice are factors that unnecessarily prolong preoperative fasting, which however appears to be multifactorial. Service improvement by abbreviation of the observed fasting periods will rely on targeted staff education and effective clinical communication by provision of written information for both elective and emergency surgical patients. The routine use of preoperative nutritional supplements may need to be re-examined when further evidence is available.

Validity of surgical simulation for the assessment of operative skill.

BACKGROUND: Surgical simulators are being promoted as a means of assessing a surgeon's technical skills. Little evidence exists that simulator performance correlates with actual technical ability. This study was undertaken to determine the criterion and construct validity of currently available surgical simulations in the evaluation of technical skill. METHODS: Simulator assessment was carried out on 36 basic surgical trainees, 37 surgically naïve first-year medical students and 16 experienced general surgical consultants. Some 26 trainees and 36 students underwent repeat assessment after 6 months. A previously validated, 19-point technical skill assessment form, based on direct observation of trainee performance in the operating theatre, was also completed by each trainee's supervising consultant. RESULTS: An insignificant or weak correlation was found between simulator performance and both duration of basic surgical experience and consultant assessment of technical skill. Six months of basic surgical training led to an improvement in performance, not seen in an untrained control group, in only one of the six simulations tested. Discrimination between surgically naïve and experienced subjects was only demonstrated, in part, for four of the six tasks. CONCLUSION: The assessment of technical skill needs to be improved. Work is needed to establish the reliability and validity of currently available simulation models before they are formally introduced for high-stakes assessment.

Consultant surgeons' opinion of the skills required of basic surgical trainees.

BACKGROUND: Accurate and appropriate assessment of surgical trainees requires clear determination of the skills needed for surgical competence. This study was designed to identify those skills, rank them in order of importance and translate them into behavioural terms. METHODS: A Delphi technique, using anonymous postal questionnaires, was used. All consultant surgeons in South-East Scotland were asked to identify the skills they expected of surgical trainees. Skills identified were then returned to all consultants for weighting. Differences among specialties in the importance of each item were identified using analysis of variance. RESULTS: The qualities identified fell into five domains: technical skills, clinical skills, interaction with patients and relatives, teamwork, and application of knowledge. Consultants from all specialties gave high weightings to the generic domains of clinical skills, teamwork, and interaction with patients and relatives. CONCLUSION: This study has identified the skills considered necessary by consultant surgeons in Scotland for a successful surgical career. Contrary to expectation, consultant surgeons value many generic skills more highly than technical skills, indicating that they value well rounded doctors, not just those with technical ability. The characteristics identified are being used to develop an assessment tool for use on basic surgical trainees.

The effect of superficial venous surgery on generic health-related quality of life.

BACKGROUND: Superficial venous surgery (SVS) is associated with a significant improvement in disease-specific health related quality of life (HR-QoL) but the effect on generic HR-QoL remains uncertain. The aim of this study was to determine the effect of SVS on responses to the Short Form [SF]-36, the most widely used generic HR-QoL instrument. METHOD: Two hundred and three patients undergoing SVS completed the SF-36 pre-operatively and 24 months post-operatively. Scores for the 8 SF-36 domains [physical (PF) and social functioning (SF), role limitation due to physical (RP) and emotional (RE) problems, mental health (MH), vitality (V), pain (P), and general health perception (HP)] were calculated and normalised using UK standard data. RESULTS: Pre-operatively, patients scored significantly lower (worse) than the general UK population in PF, RP and P. Surgery was associated with a significant improvement in PF and P (45.3 vs. 42.5 and 48.9 vs. 43.8 postop vs. preop, p<0.001, WSR) at 2 years. CONCLUSION: SVS leads to a statistically and clinically significant improvement in the physical components of the SF-36. These data will allow the clinical benefits of SVS to be compared with other interventions so helping informing decisions about how venous surgery should be prioritised appropriately within the NHS.
