Implementing shared governance: a false start.

A case study of the implementation of shared governance in a large teaching hospital in Western Canada has been presented. The project was placed in jeopardy due to two major contingencies: turnover in the chief nursing executive position, and a sudden reduction in the operating budget of the nursing division necessitating significant layoffs. Other factors that threatened the survival of shared governance included lack of systematic, long-range planning; the number and diversity of major changes introduced concurrently in the nursing division; and insufficient support systems to sustain organizational change. In particular, some senior and first-line managers could not adapt to or accept the radical philosophical change and so they were unable to empower their staff and to provide the necessary reinforcement needed to ensure the success of shared governance. This combination of these factors contributed to the loss of momentum in the implementation of shared governance. Lowered morale in the wake of layoffs, together with union grievances, and lack of clarity of the role to be played by union representatives in shared governance produced conflict and confrontation within the nursing division and between union and management. Despite the difficulties encountered, there remains optimism and commitment to the challenge of making shared governance succeed. As this article goes to press, remarkable strides have been made in addressing the described issues. A task force composed primarily of staff nurses has developed a "customized" model of governance that meets the needs of the hospital and deals with the identified flaws of the first implementation attempt. The organization is optimistic that by taking time to develop a solid foundation for the proposed change and tending carefully to the details of decision-making processes, an effective structure to support the professional role of the nursing staff will be a reality.

Strategy for management of distal ileal Crohn's disease.

We have determined the outcome of a defined policy for the management of distal ileal Crohn's disease using a prospective computer-based analysis of 139 patients diagnosed between 1970 and 1988 with a mean follow-up of 10 years. The policy in outline consists of conservative treatment for acute obstructive episodes, resection or strictureplasty for recurrent obstructive episodes, surgical treatment for abscess and fistula formation and specific medical treatment (corticosteroids, immunosuppressive therapy or metronidazole) for symptomatic non-obstructive disease. Twenty-nine patients had a benign course without resection. The remainder were treated surgically at some time but only 28 of these patients had specific treatment before operation. Thirty-three needed more than one resection and five needed more than three surgical procedures. Immediate, early or delayed surgical treatment did not affect the reoperation rates or the long-term outcome. Eleven patients died, ten of causes unrelated to Crohn's disease. Of the 128 living patients, 114 are fit and well, and only two are currently taking specific medication. Fourteen are unwell of whom six either need or have refused further surgery which could restore them to good health. This management policy has achieved excellent long-term results in nearly all patients, and our findings suggest that the timing of surgery and its nature are more important in determining outcome than specific medical therapy.

Prognosis after surgery for colonic Crohn's disease.

The long-term prognosis including operation rates, the incidences of recurrent disease, morbidity and mortality and current status has been analysed in a group of 360 patients with Crohn's colitis grouped according to the primary site of macroscopic disease at diagnosis. The group has been followed from diagnosis for a mean period of 14.9 years. The overall operation rate was 76 per cent. Prolonged spontaneous or drug induced remission occurred at all sites: right-sided disease (11 per cent), extensive colonic disease (21 per cent) and left-sided disease (38 per cent). The cumulative reoperation rates at 5 and 10 years after right hemicolectomy were 26 and 46 per cent, after colectomy and ileorectal anastomosis 46 and 60 per cent, and after panproctocolectomy 10 and 21 per cent, respectively. There was a twofold excess mortality rate from related Crohn's disease deaths during the period of review, but the mortality rate has fallen with time. There have only been 11 related deaths in the last decade, of which eight were probably unavoidable. The current status of most patients is good, although treatment has included a permanent stoma in less than half (41 per cent) the patients still under review. Currently all but 14 patients are well and symptom-free and only 16 are receiving specific medical treatment. Until the aetiology of Crohn's colitis is understood, if medical treatment has failed to resolve symptoms, appropriate surgical treatment in experienced hands is an effective way of restoring patients with chronic persistent symptoms to good health.

Mortality in Crohn's disease--a clinical analysis.

We have examined the causes of death and the changing pattern of mortality over time among 769 patients with Crohn's disease under long-term review between 1944 and 1984. One hundred and fifty-six patients have died. The cause of death could not be classified in five. The deaths were divided into those related directly to Crohn's disease and unrelated deaths from incidental causes. The cause and age at death among 59 unrelated deaths was similar to that expected in the general population. The common causes of related deaths were sepsis, digestive tract cancer, pulmonary embolus and metabolic disorders. There were 30 deaths after surgery, usually from sepsis after emergency surgical treatment. There have been fewer deaths in recent years and the cause of death has altered. Sepsis and electrolyte imbalance have declined in importance and cancer of the digestive tract is now the most common cause of related death. Occasional death from sepsis occurs in elderly patients. Elective rather than emergency surgical treatment and the routine use of antimicrobial prophylaxis before surgery has probably reduced mortality. With the exception of cancer of the digestive tract the appropriate medical and surgical treatment of patients with Crohn's disease can eliminate excess mortality previously associated with the disorder.
