ABSTRACT

OBJECTIVES: Hospital Episode Statistics data are used for healthcare planning and hospital reimbursements. Reliability of these data is dependent on the accuracy of individual hospitals reporting Secondary Uses Service (SUS) which includes hospitalisation. The number and coding accuracy for Parkinson's disease hospital admissions at a tertiary centre in Birmingham was assessed. STUDY DESIGN: Retrospective, routine-data-based study. METHODS: A retrospective electronic database search for all Parkinson's disease patients admitted to the tertiary hospital over a 4-year period (2009-2013) was performed on the SUS database using International Classification of Disease codes, and on the local inpatient electronic prescription database, Prescription and Information Communications System, using medication prescriptions. Capture-recapture methods were used to estimate the number of patients and admissions missed by both databases. RESULTS: From the two databases, between July 2009 and June 2013, 1068 patients with Parkinson's disease accounted for 1999 admissions. During these admissions, the Parkinson's disease was coded as a primary or secondary diagnosis. Ninety-one percent of these admissions were recorded on the SUS database. Capture-recapture methods estimated that the number of Parkinson's disease patients admitted during this period was 1127 patients (95% confidence interval: 1107-1146). A supplementary search of both SUS and Prescription and Information Communications System was undertaken using the hospital numbers of these 1068 patients. This identified another 479 admissions. SUS database under-estimated Parkinson's disease admissions by 27% during the study period. CONCLUSION: The accuracy of disease coding is critical for healthcare policy planning and must be improved. If the under-reporting of Parkinson's disease admissions on the SUS database is repeated nationally, expenditure on Parkinson's disease admissions in England is under-estimated by approximately £61 million per year.

ABSTRACT

OBJECTIVES: To determine the incidence of bile duct reconstruction (BDR) following laparoscopic cholecystectomy (LC) and to identify associated risk factors. BACKGROUND: Major bile duct injury (BDI) requiring reconstruction is a serious complication of cholecystectomy. METHODS: All LC and attempted LC operations in England between April 2001 and March 2013 were identified. Patients with malignancy, a stone in bile duct or those who underwent bile duct exploration were excluded. This cohort of patients was followed for 1 year to identify those who underwent BDR as a surrogate marker for major BDI. Logistic regression was used to identify factors associated with the need for reconstruction. RESULTS: In total, 572,223 LC and attempted LC were performed in England between April 2001 and March 2013. Five hundred (0.09 %) of these patients underwent BDR. The risk of BDR is lower in patient that do not have acute cholecystitis [odds ratio (OR) 0.48 (95 % CI 0.30-0.76)]. The regular use of on-table cholangiography (OTC) [OR 0.69 (0.54-0.88)] and high consultant caseload >80 LC/year [OR 0.56 (0.39-0.54)] reduced the risk of BDR. Patients who underwent BDR were 10 times more likely to die within a year than those who did not require further surgery (6 vs. 0.6 %). CONCLUSIONS: The rate of BDR following laparoscopic cholecystectomy in England is low (0.09 %). The study suggests that OTC should be used more widely and provides further evidence in support of the provision of LC services by specialised teams with an adequate caseload (>80).

ABSTRACT

BACKGROUND: The aim of this study was to investigate whether the increased mortality previously identified for surgery performed on Fridays was apparent following major elective colorectal resections and how this might be affected by case mix. METHODS: Patients undergoing elective colorectal resections in England from 2001 to 2011 were identified using Hospital Episode Statistics. Propensity scores were used to match patients having operations on a Friday in a 1 : 1 ratio with those undergoing surgery on other weekdays. Multivariable analyses were used to investigate overall deaths within 1 year of operation. RESULTS: A total of 204,669 records were extracted for patients undergoing major elective colorectal resections. Patients who had surgery on Fridays were more deprived (4780 (17.1 per cent) of 27,920 versus 28,317 (16.0 per cent) of 176,749; P < 0.001), a greater proportion had had an emergency admission in the 3 previous months (7870 (28.2 per cent) of 27,920 versus 48,623 (27.5 per cent) of 176,749; P = 0.019), underwent minimal access surgery (4565 (16.4 per cent) of 27,920 versus 23,783 (13.5 per cent) of 176,749; P < 0.001) and had surgery for benign diagnoses (6502 (23.3 per cent) of 27,920 versus 38,725 (21.9 per cent) of 176,749; P < 0.001) than those who had surgery on Mondays to Thursdays. In a matched analysis the odds ratio for 30-day mortality after colorectal resections performed on Fridays compared with other weekdays was 1.25 (95 per cent c.i. 1.13 to 1.37); odds ratios for 90-day and 1-year mortality were 1.16 (1.07 to 1.25) and 1.10 (1.04 to 1.16) respectively. CONCLUSION: Patients selected for colorectal resections on Fridays had a higher mortality rate than patients operated on from Monday to Thursday and had different characteristics, suggesting that increased mortality may reflect patient factors rather than hospital variables alone.
