Randomized clinical trial of the effectiveness of emergency day surgery against standard inpatient treatment

Improving Quality Metrics with a Day-only Skin Abscess Protocol: Experience from Australia

BACKGROUND

Skin abscesses are a common emergency presentation often requiring incision and drainage; however, issues with theatre access lead to delays in management and high costs. The long-term impact in a tertiary centre of a standardised day-only protocol is unknown. The aim was to evaluate the impact of day-only skin abscess protocol (DOSAP) for emergency surgery of skin abscesses in a tertiary institution in Australia and to provide a blueprint for other institutions.

METHODS

A retrospective cohort study analysed several time periods: Period A (July 2014 to 2015, n = 201) pre-DOSAP implementation, Period B (July 2016 to 2017, n = 259) post-DOSAP, and Period C (July 2018 to 2022, n = 1,625) prospectively analysed four 12-month periods to assess long-term utilisation of DOSAP. Primary outcomes were length of stay and delay to theatre. Secondary outcome measures included theatre start time, representation rates and total costs. Statistical analysis using nonparametric methods was used to analyse the data.

RESULTS

There was a significant decrease in ward length of stay (1.25 days vs. 0.65 days, P < 0.0001), delay to theatre (0.81 days vs. 0.44 days, P < 0.0001) and theatre start time before 10AM (44 cases vs. 96 cases, P < 0.0001) after implementation of DOSAP. There was a significant decrease in median cost of admission of $711.74 after accounting for inflation. Period C reported 1,006 abscess presentations successfully managed by DOSAP over the four-year period.

CONCLUSION

Our study demonstrates the successful implementation of DOSAP in an Australian tertiary centre. The ongoing utilisation of the protocol demonstrates the ease of applicability.

Current and Projected Financial Burden of Emergency General Surgery for Adults in Scotland's Single Payer Healthcare System: A Cost Analysis of Hospital Admissions

OBJECTIVE

To calculate the current and projected financial burden of EGS hospital admissions in a single-payer healthcare system.

SUMMARY OF BACKGROUND DATA

EGS is an important acute care service, which demands significant healthcare resources. EGS admissions and associated costs have increased over time, associated with an aging demographic. The National Health Service is the sole provider of emergency care in Scotland.

METHODS

Principal, high and low Scottish population projections were obtained for 2016 until 2041. EGS admission data were projected using an ordinary least squares linear regression model. An exponential function, fitted to historical length of hospital stay (LOS) data, was used to project future LOS. Historical hospital unit cost per bed day was projected using a linear regression model. EGS cost was calculated to 2041 by multiplying annual projections of population, admission rates, LOS, and cost per bed day.

RESULTS

The adult (age >15) Scottish population is projected to increase from 4.5 million to 4.8 million between 2016 and 2041. During this time, EGS admissions are expected to increase from 83,132 to 101,090 per year, cost per bed day from £786 to £1534, and overall EGS cost from £187.3 million to £202.5 million.

CONCLUSIONS

The future financial burden of EGS in Scotland is projected to increase moderately between 2016 and 2041. This is in sharp contrast to previous studies from settings such as the United States. However, if no further reductions in LOS or cost per bed day are made, especially for elderly patients, the cost of EGS will rise dramatically.

Fast-track ambulatory abscess pathway: an Australian streamlined emergency surgery pathway

BACKGROUND

Superficial skin abscesses account for a significant burden of emergency surgical admissions. The aim of this study was to evaluate the effectiveness of an ambulatory care pathway for emergently treating abscesses of the body requiring operative drainage.

METHOD

A retrospective study of a prospective patient database was performed, using randomized patient selection. Patient demographics, length and cost of stay were compared between patients undergoing operative management for skin abscess before and after the implementation of the fast-track ambulatory abscess pathway (FAAP).

RESULTS

In total, 100 patients were analysed with 50 in the pre-ambulatory care pathway group and 50 in the FAAP group. The pre-ambulatory care pathway group had a mean age of 37.7 ± 15.8 years versus FAAP group of 35.3 ± 14.5 years. Total length of stay for the group was 85 versus 17 days with a mean comparison of 1.7 days versus 0.34 days (P < 0.001). This translated into a total cost saving of $74 100 in the FAAP group, with a mean comparison cost between the groups of $2884 versus $1402 (P < 0.001). Both reductions in length of stay and cost of stay were statistically significant after implementation of the pathway.

CONCLUSION

This is the first Australian study to report the findings from an ambulatory care pathway for an emergency surgical intervention. We have shown that skin abscesses presenting through emergency can be managed as a day-case procedure, thereby decreasing these patients' overall length and cost of stay.

Management of superficial abscesses: scope for day case surgery

Background. Patients presenting with superficial abscesses are often regarded as low priority and given a less efficient service. Aim. The aim of this study was to investigate the efficiency of emergency treatment of superficial abscesses and to identify areas for service improvement. Method. A retrospective case review of patients admitted to Derriford Hospital, Plymouth, over a four-month period. Results. Ninety-seven patients were included in the study. Seventy two (74%) arrived between 08.00 and 16.00 hours. Overall, 75 patients (77%) were referred on weekdays with 22 patients (23%) during weekends. Seventy-two patients (74%) had treatment under a general anaesthetic. Sixty-three percent of operations occurred within the working day. The time interval between admission and surgery ranged from 52 minutes to 38 hours (mean ± SD 16 ± 9.15). The length of admission ranged from 5.3 hours to 11 days (mean 36 hours). Of the one hundred overnight beds used by the 97 patients, 30 nights were spent awaiting surgery and 70 following surgery and awaiting discharge. Conclusion. Eighty-nine percent of the patients would have been suitable for treatment as day cases. This review shows that a simple service redesign has the potential of reducing inpatient bed occupancy and improving the patient's journey.

Reimbursement systems, organisational forms and patient selection: evidence from day surgery in Norway

Cream skimming can be defined as the selective treatment of patients that demand few resources while providing high economic refunds. We test whether cream skimming occurs after the introduction of DRG-based activity-based financing (ABF) in Norway in 1997 and if the problem further increased after the 2002 organizational reform when hospitals were turned into trusts. The DRG-system offers the same economic reimbursement for patients classified within day-surgical DRGs irrespective of whether the patient receives same-day treatment or in-patient care over several days. This provides potential for cream skimming and allows us to investigate cream skimming within the actual diagnoses. Patient data from the period 1999-2005 is analyzed. Waiting times are used as indicators of patient selection and analyzed as a function of severity within each diagnosis, controlling for age and gender of the patient, as well as institutional and time-dependent variables. The analysis gives some evidence of cream skimming in the first period of ABF, in particular within the lighter orthopaedic diagnoses. However, cream skimming does not increase after the 2002 organizational reform but is stable, and for some DRGs even reduced. The study indicates that cream skimming may occur if reimbursement systems are not particularly sophisticated. Softening of budget constraints after the hospital reform of 2002 may explain why cream skimming does not increase after the reform. However, further investigation into this mechanism is needed.

A methodology to estimate the potential to move inpatient to one day surgery

BACKGROUND

The proportion of surgery performed as a day case varies greatly between countries. Low rates suggest a large growth potential in many countries. Measuring the potential development of one day surgery should be grounded on a comprehensive list of eligible procedures, based on a priori criteria, independent of local practices. We propose an algorithmic method, using only routinely available hospital data to identify surgical hospitalizations that could have been performed as one day treatment.

METHODS

Moving inpatient surgery to one day surgery was considered feasible if at least one surgical intervention was eligible for one day surgery and if none of the following criteria were present: intervention or affection requiring an inpatient stay, patient transferred or died, and length of stay greater than four days. The eligibility of a procedure to be treated as a day case was mainly established on three a priori criteria: surgical access (endoscopic or not), the invasiveness of the procedure and the size of the operated organ. Few overrides of these criteria occurred when procedures were associated with risk of immediate complications, slow physiological recovery or pain treatment requiring hospital infrastructure. The algorithm was applied to a random sample of one million inpatient US stays and more than 600 thousand Swiss inpatient stays, in the year 2002.

RESULTS

The validity of our method was demonstrated by the few discrepancies between the a priori criteria based list of eligible procedures, and a state list used for reimbursement purposes, the low proportion of hospitalizations eligible for one day care found in the US sample (4.9 versus 19.4% in the Swiss sample), and the distribution of the elective procedures found eligible in Swiss hospitals, well supported by the literature. There were large variations of the proportion of candidates for one day surgery among elective surgical hospitalizations between Swiss hospitals (3 to 45.3%).

CONCLUSION

The proposed approach allows the monitoring of the proportion of inpatient stay candidates for one day surgery. It could be used for infrastructure planning, resources negotiation and the surveillance of appropriate resource utilization.
