Surgical audit: the value of a morbidity and mortality conference

The role of morbidity and mortality rounds in medical education: a scoping review

CONTEXT

There is increasing focus on how health care professionals can be trained effectively in quality improvement and patient safety principles. The morbidity and mortality round (MMR) has often been used as a tool with which to examine and teach care quality, yet little is known of its implementation and educational outcomes.

OBJECTIVES

The objectives of this scoping review are to examine and summarise the literature on how the MMR is designed and delivered, and to identify how it is evaluated for effectiveness in addressing medical education outcomes.

METHODS

A literature search of the PubMed, MEDLINE, PsycInfo and Cochrane Library databases was conducted for articles published from 1980 to 1 June 2016. Publications in English describing the design, implementation and evaluation of MMRs were included. A total of 67 studies were identified, including eight survey-based studies, four literature reviews, one ethnographic study, three opinion papers, two qualitative observation studies and 49 case studies of education programmes with or without formal evaluation. Study outcomes were categorised using Donald Moore's framework for the evaluation of continuing medical education (CME).

RESULTS

There is much heterogeneity within the literature regarding the implementation, delivery and goals of the MMR. Common design components included explicit programme goals and objectives, the case selection process, case presentation models and some form of case analysis. Evaluation of CME outcomes for MMR were mainly limited to learner participation, satisfaction and self-assessed changes in knowledge.

CONCLUSIONS

The MMR is widely utilised as an educational tool to promote medical education, patient safety and quality improvement. Although evidence to guide the design and implementation of the MMR to achieve measurable CME outcomes remains limited, there are components associated with positive improvements to learning and performance outcomes.

Morbidity and mortality conference, grand rounds, and the ACGME's core competencies

Morbidity and Mortality (M&M) Conferences are an Accreditation Council for Graduate Medical Education (ACGME) mandated educational series that occur regularly at all institutions that have residency training programs. The potential for learning from medical errors, complications, and unanticipated outcomes is immense--provided that the focus is on education, as opposed to culpability. The education innovation described in this manuscript is the manner in which we have used the ACGME Outcome Project's 6 core competencies as the structure upon which the cases discussed at our M&M conference are framed. When presented at grand rounds in a novel format, M&M conference has not only maintained support for the quality improvement efforts in the Department, but has served to improve the educational impact of the conference.

Infantile hypertrophic pyloric stenosis: long-term audit from a general surgical unit

This article describes a 22 year experience of a general surgical unit in the treatment of infantile hypertrophic pyloric stenosis (IHPS). The hospital course of 229 IHPS patients is reviewed. The male:female ratio was 3.6:1, median age 6 weeks (range 2-26 weeks) with a positive family history in 8.3%. The diagnosis of IHPS was established clinically by palpation of a "pyloric tumour" during a pre operative test meal/clinical examination in 92.6%; in the remainder, the diagnosis was made radiologically. Ramstedt's pyloromyotomy was performed within 5 days of admission in 74% of patients and within 10 days of admission in 89%. The median post-operative hospital stay was 10 days (range 3-60 days). Wound morbidity occurred in 10.0% wound infection (7.3%) and wound dehiscence (2.6%). However, wound morbidity was reduced in the second half of the series, partly by greater utililisation of non-absorbable suture in place of chromic catgut for wound closure. Mucosal penetration was suspected in 14.8% of cases. Repeat pyloromyotomy was necessary in 1.3%. One baby died (0.4%)- this was in the early part of the series and was directly attributable to fluid and electrolyte disorder. We conclude that Ramstedt's pyloromyotomy for infantile hypertrophic pyloric stenosis can be performed with acceptable morbidity and minimal mortality in a general surgical unit.

A review of the nature and activity of a general surgical service in Ireland

The steady increase in hospital costs has led to demands for closer scrutiny of activity levels, workloads and outcomes. This study sought to examine these parameters in a typical district general surgical unit in this country. In the five year period 1985-89, 11,227 inpatient and 3,354 outpatient procedures were performed; 83% of the inpatient procedures were elective and 17% were emergency surgical operations. All inpatient procedures were categorized: minor (41%), intermediate (42%) and major (17%). A prospective one year review in 1990/1991 confirmed the accuracy of the retrospective data. During that year 2,335 inpatient operations and 765 outpatient operations were performed, of which 80.5% of the inpatient operations were elective and 19.5% were emergency procedures. Of these 16.6% were major, 34.4% intermediate and 49% were minor operations. 60% of the operations were performed by consultants. The in-hospital surgical mortality for the 1 year prospective review was 1.35% and the perioperative mortality was 0.64%. The overall operation morbidity rate was 9% and the procedure-related morbidity was 4.7%. The wound infection rate was 2%. Of the common operations performed throughout the six year study period appendicectomies and external hernia operations accounted for 20% of the caseload; 14% were urological, 7% were breast and 6% were biliary operations. The average waiting time for elective admissions was less than 4 weeks. The average length of hospital stay and the bed occupancy rates did not change.

Surgical audit under scrutiny--a prospective study

Surgical audit must be shown to improve clinical practice and patient outcome if its widespread introduction is to be enthusiastically embraced by surgeons. Retrospective studies on hospital activity by their nature are often incomplete and unreliable. A 12-month prospective review (July 1990-June 1991) of the activity, morbidity and mortality that occurred within a district general surgical unit is analysed. During the study period, 3,927 patients were admitted to the unit, of whom 1,649 were elective and 2,278 (58%) were emergency cases. 48 patients (1.2%) were transferred to external specialist centres. 41% of the admissions did not require surgery. There were 2,335 in-patient and 765 out-patient operations performed. Using the BUPA classification (n = 3100), there were 388 major (12.5%), 802 intermediate (25.9%) and 1910 minor (61.6%) procedures. There were 15 perioperative and 38 non-operative (27 metastatic carcinoma) deaths. 80% of the perioperative deaths were high risk, elderly patients with acute abdominal pathology. 369 complications (39 in non-operative cases) were recorded among both in- and out-patients: 212 systemic, 133 local/wound and 24 major/life threatening. The perioperative mortality rate was 0.6%. The operative morbidity rate was 9.0% and the procedure-related morbidity 4.7%. The wound infection rate was 2%. In a non-specialist, general surgical unit with a broad case mix, it is possible to provide a standard of care and practice that produces very low mortality and an acceptable morbidity rate.

Surgical emergencies in Ireland. An audit of the emergency surgical caseload of an Irish district general hospital

Emergency cases are an increasing part of the workload of a general surgical unit. Little accurate quantitative data is presently available on the nature and impact of this workload on a typical district general surgical service. This study reports the results of a prospective one year audit of the emergency cases dealt with by a typical Irish district general surgical service. The general surgical service admitted 2,278 patients acutely, which represented 58% of the total number of admissions to the service. Eighteen patients required immediate transfer for specialist neurosurgical (11), vascular (6) or plastics (1) treatment. Of those cases admitted 1,396 (61.3%) were males and 882 (38.7%) were females. There were 1,786 (78%) adults and 492 (21.6%) paediatric cases. Abdominal pain (48.0%), head injury (23.8%) and urological problems (11.0%) accounted for the majority of the caseload. Within the abdominal pain group, the pre-dominant diagnoses were non-specific abdominal pain (36.0%), appendicitis (19.5%), cholecystitis/obstructive jaundice (10.8%) and peptic ulcer disease (10.0%). There were 456 emergency operations performed, representing 19.5% of all the inpatient general surgical procedures. 328 (72%) of these were performed out of normal working hours. Only 12% of the procedures were major. The commonest operations were appendicectomy (51%), abscess drainage (13%), wound toilet (13%) and laparotomy (11%). The emergency peri-operative mortality was 1.1%. The positive appendicectomy rate was 92%.

Developing a system for surgical audit

A system for surgical audit, which has been developed during a 6 year period in an active surgical unit of a teaching hospital, is described. Following a review of the first 3 years of our computerized audit, major modifications to the audit processes and computer program were made. The key lessons for systematic practical surgical audit include the collection of essential data only, establishing audit processes within current department practices, verification of data by consultants, and the provision of incentives for all users. The current system is proving a valuable resource for quality assurance, surgical training and departmental management.
